Description

  The present invention relates to a refrigerator structure having a high energy saving effect.

  FIG. 18 is a cross-sectional view of the basic structure of a freezer compartment of a conventional refrigerator.

  As shown in FIG. 18, a gasket 12 is provided at the end of the inner surface of the door 11 over the entire circumference, and a metal contact member formed on the front surface of the partition 13 that forms the receiving surface of the gasket 12. 14 and gasket 12 are brought into close contact with each other to prevent cold air from leaking to the outside.

  Cold air generated by a cooler 15 installed on the back of the main body is blown out from the discharge port 17 on the back of the freezer compartment 25 by a fan 16 to cool the food stored therein.

  Then, the cold air that has cooled the food reaches the upper front part of the storage cases 18 and 19, as shown by the arrows, and the space between the inner wall of the door 11 and the front surfaces of the storage cases 18 and 19, and the bottom surface of the storage case 19. Circulation returns from the return duct 21 to the cooler 15 through the space with the bottom wall of the storage chamber.

The heat radiating pipe 23 uses a high-temperature refrigerant pipe in a refrigeration cycle (not shown), and the heat of the partition 13 is heated to a high temperature by the heat. The front upper air was heated and the cooling efficiency was reduced.

  In order to prevent this, a mechanism has been proposed in which a seal member 24 indicated by a two-dot chain line is provided in the upper space portion of the storage case 18 in the vicinity of the partition 13 to shield the cold air flow toward the gasket 12 (for example, Patent Document 1).

  However, in the above-described conventional configuration, in order to prevent the cool air in the storage chamber from being heated by heat exchange with the heated metal abutting member, a seal member is provided on the partition body so as to avoid contact with the storage case. The cool air flow to the metal contact member is shielded in contact, but if the sealing performance deteriorates due to aging deterioration of the seal member, etc., the cold air cannot be shielded, and the high temperature metal contact member and heat There was a problem that the cooling efficiency was lowered due to the replacement and heating the cold air.

  As shown in FIG. 1, the box body 101 of the refrigerator 100 includes an outer box 102 mainly using a steel plate and an inner box 103 molded with a resin such as ABS. Between them, for example, a foam heat insulating material such as hard foam urethane is filled. The refrigerator 100 is insulated from the surroundings mainly by the box body 101. The box body 101 is divided into a plurality of storage rooms. A refrigeration room 104 as a storage room is arranged at the top of the box body 101, a vegetable room 105 as a storage room at the bottom of the refrigeration room 104, and a freezing room 106 as a storage room at the bottom.

  The front opening of each storage chamber is closed by a door 117, a door 118, and a door 119 so as to be opened and closed.

  The refrigerator compartment 104 is set to a lower limit of a temperature at which it does not freeze for refrigerated storage, and is usually set in a range of 1 ° C to 5 ° C. The vegetable room 105 is set to a temperature equal to or slightly higher than that of the refrigerated room 104, and is usually set in a range of 2 ° C to 7 ° C. The freezer compartment 106 is set in a freezing temperature zone for frozen storage, and is usually set in the range of −22 ° C. to −15 ° C. The freezer compartment 106 may be set at a low temperature of, for example, −30 ° C. or −25 ° C. in order to improve the frozen storage state. In addition, the vegetable room 105 can be switched to a freezing room and is set up to −18 ° C., but will be described as a vegetable room in the following description.

  A machine room 107 is provided in the lowermost region of the freezer compartment 106 at the bottom of the box body 101. The machine room 107 accommodates high-pressure components of the refrigeration cycle such as the compressor 108 and a dryer (not shown) for removing moisture.

  As shown in FIG. 2, a cooling chamber 109 that generates cold air is provided on the back surface of the freezing chamber 106. Between the freezer compartment 106 and the cooling chamber 109, a back partition wall 110 having heat insulation is provided. The rear surface partition wall 110 is for forming a cold air conveying air passage to each room and partitioning it from each room. A cooler 111 is disposed in the cooling chamber 109. A cooling fan 112 is disposed in the upper space of the cooler 111 to blow the cold air cooled by the cooler 111 by a forced convection method to the refrigerator compartment 104, the vegetable compartment 105, and the freezer compartment 106. In the lower space of the cooler 111, a radiant heater 113 made of a glass tube is provided for defrosting the frost and ice adhering to the cooler 111 and its periphery during cooling. Further, at the lower part of the radiant heater 113, a drainage tray 114 for receiving defrosted water generated at the time of defrosting and draining it outside the warehouse is provided, and an evaporating dish 116 is provided outside the warehouse on the downstream side.

  The rear partition wall 110 has a discharge port 115 for guiding the cool air generated by the cooler 111 to the freezer compartment 106 by the cooling fan 112 and a suction for returning the cool air circulated in the freezer compartment 106 to the cooler 111. A mouth 117 is provided.

  A storage case 126 for storing foods is disposed in the freezer compartment 106. The storage case 126 is pulled out together with the drawer.

  As shown to FIG. 3A, the gasket 121 is provided in the edge part of the inner surface of the door 119 over the perimeter (it is the same also in the refrigerator compartment 104 and the vegetable compartment 105). The gasket 121 prevents the cool air inside the freezer compartment 106 and the vegetable compartment 105 from leaking to the outside by being in close contact with a metal contact member 123 provided on the front surface of the partition 122. Here, the partition 122 is formed of a resin that is a member that vertically separates the vegetable compartment 105 and the freezing compartment 106.

  Furthermore, the partition 122 forms a suppressing portion 124 in the vicinity of the contact member 123 (downward in the case of the present embodiment). The suppression unit 124 is a part of the partition 122 that prevents the contact member 123 from directly contacting the inner space of the vegetable compartment 105 or the freezing compartment 106, and the temperature of the vegetable compartment 105 or the freezing compartment 106 rises due to heat conduction. That is restrained. Thus, the suppression part 124 is a heat conduction suppression part which suppresses the heat conduction which generate | occur | produces when an object, ie, solid, contact | abuts among the suppression parts which suppress heat | fever penetration | invasion.

  Further, a heat radiating pipe 131 is disposed at a portion of the partition 122 that contacts the back surface of the contact member 123. The heat radiating pipe 131 is a tube body for preventing the front portion of the partition 122, that is, the contact member 123 from condensing, and the heat radiating pipe 131 has a high temperature refrigerant in the refrigeration cycle (not shown) inward. It is in circulation. Therefore, the contact member 123 is heated by heat exchange with the high-temperature refrigerant to suppress the occurrence of condensation.

As shown in FIGS. 4 and 5, the suppressing portion 124 is below the abutting member 123 and is located in the partition 12.
2 across the entire width direction. Moreover, the opening part 128 is provided in the both ends of the width direction of the suppression part 124. FIG. The opening 128 has a protruding shape protruding outward in the width direction, and is inserted into an insertion hole 127 provided in a portion corresponding to both side walls of the inner box 103. By inserting the opening 128 into the box body 101 as described above, the front portion of the partition 122 is fixed to the box body 101.

  As shown in FIG. 6, a heat insulating member 134 is disposed on the inner side of the heat radiating pipe 131 disposed on the back surface of the contact member 123. The heat insulating member 134 suppresses heat from entering from the heat radiating pipe 131 into the cabinet through the partition 122. Further, the foamed heat insulating material 130 is filled in the suppressing portion 124 provided in the lower portion of the contact member 123. Thereby, the heat insulation efficiency of the suppression part 124 is improved and it is suppressing that a heat | fever penetrate | invades directly into the store | warehouse | chamber from the contact member 123. FIG.

  In addition, the partition body 122 is provided with an air hole 132 that communicates the inside and the outside of the suppressing portion 124 in addition to the opening portion 128, so that the foam heat insulating material is filled through the opening portion 128 on the side surface of the partition body 122. The fluidity of 130 can be improved, and the foam insulating material 130 can be surely filled in the entire restraining portion 124 to ensure heat insulation. The air holes 132 are provided from the suppressing portion 124 toward the back side of the refrigerator 100, and the partition 122 further includes a foam heat insulating material storage space 133 on the back side of the air holes 132, thereby The foam insulation 130 is prevented from overflowing into the storage chamber.

  As shown in FIG. 7, the partition 122 includes an upper partition plate 135 and a lower partition plate 136, and is formed by combining the upper partition plate 135 and the lower partition plate 136 vertically. In addition, the suppression unit 124 is also configured by the upper partition plate 135 and the lower partition plate 136. The partition 122 suppresses heat exchange between the upper and lower partition plates 136 and the lower partition plate 136 by sandwiching the heat insulating member 137 between the upper and lower temperature zones.

  As shown in FIGS. 8 and 9, the upper partition plate 135 includes a convex portion 140, and the position of the upper and lower partition plates in the front-rear direction is regulated by fitting with the concave portion 142 provided in the lower partition plate 136. . By fitting the convex portion 140 and the concave portion 142, the appearance quality is ensured and the outflow of the foam heat insulating material is achieved. Further, by engaging with the claw portion 141 provided on the upper partition plate 135 and the concave portion 143 provided on the lower partition plate 136, the vertical position of the upper and lower partition plates is regulated, ensuring appearance quality and foam insulation. We are trying to control the outflow of materials.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the flow of cold air in the freezer compartment 106 will be described. The cool air cooled by the cooler 111 is forcibly blown from the discharge port 115 to the upper, middle, and lower stages in the freezer compartment 106 by the cooling fan 112 that rotates as the motor rotates. The cold air blown out blows the storage case 126 to cool the food stored. As shown by the arrow, the cool air that has cooled the food is sucked from the suction port 117 through the gap between the storage case 126 and the inner box bottom wall, and returns to the cooler 111.

  As described above, when the cold air circulates in the freezer compartment 106, it is heated by exchanging heat with a relatively high-temperature portion such as a wall surface. The abutting member 123 heated by the heat radiating pipe 131 is hot against the cold air, but the abutting member 123 and the cold air are in direct contact with each other by providing the suppression portion 124 at the lower part of the abutting member 123. Has been avoided. Accordingly, it is possible to suppress the warming of the cold air, improve the cooling efficiency, and consequently reduce the power consumption.

  In addition, since the cooling of the cold air can be suppressed, the cold air circulates at a low temperature, so that the entire temperature distribution in the freezer compartment 106 can be kept uniform.

  Moreover, by providing the suppression part 124 in the lower part of the contact member 123, the contact between the gasket 121 and the cold air can be reduced, and heat exchange via the gasket 121 can be suppressed. Furthermore, since the gasket 121 comes into contact with the abutting member 123 and becomes relatively high in temperature, contact with cold air is suppressed, so that the heat exchange suppressing effect can be further improved. In order to exhibit this effect, it is desirable that the step in the front-rear direction between the contact member 123 and the partition front surface 122a is 5 mm or less. When the level difference becomes large, it becomes difficult to close the gap between the gasket 121 and the partition front surface portion 122a with the flexibility of the gasket 121, and the heat exchange suppressing effect is reduced.

  Due to the above effects, the contact member 123 is cooled by heat exchange with the contact member 123, and the contact member 123 is prevented from being condensed due to a sudden temperature difference between the inside and outside of the contact member 123. You can also.

  Moreover, the heat exchange from the heat radiating pipe to the surface in contact with the cold air can be further suppressed by filling the foamed heat insulating material 130 having high heat insulating efficiency in the suppressing portion 124 provided below the contact member 123.

  The partition 122 is configured by sandwiching and assembling a heat insulating member 137 between an upper partition plate 135, a lower partition plate 136, and upper and lower partitions.

  The partition body 122 is provided with an opening 128 having a convex peripheral edge on both side surfaces of the restraining portion 124, and the convex opening 128 is inserted into and fixed to the insertion hole 127 provided in the inner box 103. Is done. Since the partition 122 includes the convex opening 128, the opening 128 can be protruded from the inner box 103 toward the outer box 102, so that it becomes easy to fill the foam heat insulating material 130 inside the suppressing part 124. . For this reason, the filling property of the foam heat insulating material 130 in the suppression part 124 can be improved. Further, by setting the gap between the convex opening 128 and the insertion hole 127 to 1 mm or less, the foam heat insulating material 130 flowing from the opening 128 leaks into the storage room of the refrigerator, and impairs the quality in the cabinet. Suppress. By fixing the convex opening 128 to the insertion hole 127, the front-rear positional relationship between the partition 122 and the inner box 103 is determined, so that the front-rear position of the partition 122 can be restricted.

  Since the foam heat insulating material 130 injected from the openings 128 at both ends of the suppressing portion 124 has a characteristic that it does not easily flow in a sealed space, an air hole 132 is provided in the center of the suppressing portion 124 for allowing air in the space to escape. As a result, the foamed heat insulating material 130 can be reliably filled in the suppressing portion 124.

  In the present embodiment, the air hole 132 is provided at one central position, but it may be provided at a place other than the center or at a plurality of places depending on the flow state of the foam heat insulating material 130. Since the foamed heat insulating material 130 filled in the suppressing part 124 tends to leak outside through the gap existing in the suppressing part 124, there is a high possibility of leaking from the air hole 132. Therefore, by providing the foamed heat insulating material storage space 133 that can store the leaked foam heat insulating material 130 on the storage chamber side of the air hole, the foam heat insulating material 130 that has flowed in more than the volume of the suppressing portion 124 is positively insulated by foaming. By flowing into the material storage space 133, the foam heat insulating material 130 is prevented from leaking to the exterior side or the storage chamber side and deteriorating the exterior quality.

  Further, in the process of filling the foam heat insulating material 130 between the outer box 102 and the inner box 103, the suppression unit 124 is also filled, so that the man-hours and the number of parts can be reduced.

Further, in order to fit the upper partition plate 135 and the lower partition plate 136 constituting the suppressing portion 124 respectively, the upper partition plate 135 has a convex portion 140 and a claw portion 141, and the lower partition plate has concave portions 142 and 143. Provided. In this specification, in order to minimize the amount of material used without increasing the number of parts, the restraining portion 124 is composed of only the upper partition plate 135 and the lower partition plate 136, so that the upper and lower partition plates are assembled. This is to suppress a gap between components that sometimes occurs in the suppressing portion 124.

  By fitting the convex portion 140 provided on the upper partition plate with the concave portion 142 provided on the lower partition plate, the upper and lower partition plates are pushed out by the foaming pressure when the foam insulating material 130 is filled in the suppression portion 124, thereby It is possible to suppress the generation of a gap between the two parts, and to suppress the appearance-side partition body front surface portion 122a from being deformed and being pushed forward from the metal contact member 123, thereby deteriorating the appearance quality due to the deformation. Suppress. Further, by engaging the claw portion 141 provided on the upper partition plate with the recess 143 provided on the lower partition plate, it is possible to suppress the occurrence of a gap between the parts of the upper and lower partition plates constituting the suppression portion 124 as described above. Therefore, it is suppressed from being deformed downward by the foaming pressure.

  Further, in the deformation due to the foaming pressure of the upper and lower partition plates constituting the restraining portion 124, the strength of the parts is improved, the partition body 122 constituting the restraining portion 124 is pressed from the front by the foaming jig, and further pressed from below by the movable jig. . Thereby, it can suppress that the foaming heat insulating material 130 which a foaming pressure exerts leaks to the external appearance side, and the partition body 122 which comprises the control part 124 deform | transforms, and can ensure appearance quality.

  By making the appearance shape of the partition front surface portion 122a, which is the appearance side of the partition body 122 constituting the suppressing portion 124 in the present invention, to be rectangular, it has a sense of unity with peripheral components such as the contact member 123 and the inner box 103. Let This is because when the door 119 is opened, when the periphery of the partition body is exposed, the appearance quality is not impaired, and the effect of suppressing heat exchange after the door is closed is exhibited. Although the appearance of the front surface 122a of the partitioning body is considered to be the most beautiful, the shape of the non-rectangular shape such as a curved shape has a sense of unity as a whole due to the shape of the peripheral parts, etc. In this case, it is possible to consider other shapes.

  In addition, although the heat insulating member 137 is sandwiched between the upper and lower partition plates in the partition 122, the heat insulating effect may be obtained by filling the foam heat insulating material instead of the heat insulating member 137.

  As described above, the refrigerator 100 according to the present embodiment uses the partition 122 to divide the inside of the box body 101 into a plurality of storage rooms to which cold air is supplied. A door that can be opened and closed is provided in front of each storage room. The door is provided with a gasket 121 that is in close contact with a metal contact member 123 formed on the front side of the partition 122.

  The refrigerator 100 includes a configuration that heats the contact member 123 and the gasket 121, and a suppression unit 124 that suppresses heat exchange between the cool air in the storage chamber and the contact member 123. Since the heat insulating material can be disposed between the contact member 123 and the storage chamber by the suppressing unit 124, the heat transfer to the surface where the contact member 123 that has become high temperature by the heat radiating pipe 131 and the cold air contact, Since the heat insulating material with low thermal conductivity is interposed, the temperature is reduced and the temperature rise of the surface in contact with the cold air can be prevented, and heat exchange can be suppressed. Accordingly, it is possible to suppress the warming of the cold air, improve the cooling efficiency, and consequently reduce the power consumption.

  In addition, as shown in FIG. 3A, the suppressing portion 124 is not only disposed above or below the contact member 123, but also above the contact member 123, as shown in FIG. 3B. And it may be arranged below.

It is possible to apply in combination.

  As shown in FIG. 10, a gasket 121 is provided on the entire periphery of the inner periphery of the door 119 (the same applies to the refrigerator compartment 104 and the vegetable compartment 105). The partition 122 is made of resin and is a member that divides the vegetable compartment 105 and the freezing compartment 106 vertically. Further, a metal contact member 123 is provided on the front surface of the partition 122, and the storage chamber is sealed by the contact member 123 and the gasket 121 being in close contact with each other.

  A heat radiating pipe 131 is disposed on the back of the contact member 123.

  Further, below the abutting member 123, a suppressing portion 124 configured by the partition body 122 is formed by the partition body 122. In the case of the present embodiment, the back side of the suppression unit 124 is in an open state, and the internal space of the suppression unit 124 and the internal space of the partition 122 are connected. A heat insulating member 137 is incorporated and fixed in the two integrated internal spaces.

  About the refrigerator comprised as mentioned above, the operation | movement / effect | action is demonstrated below. In addition, description about the operation | movement and effect | action similar to Embodiment 1 is abbreviate | omitted.

  By integrating the heat insulating member 137 disposed in the partition 122 up to the internal space of the suppressing portion 124 provided below the contact member 123, the number of parts and the number of man-hours can be reduced. Moreover, since the boundary between the suppressing unit 124 and the partition 122 is eliminated and the generation of gaps is suppressed, heat exchange between the storage chambers in different upper and lower temperature zones can be suppressed.

  In the present embodiment, the heat insulating member 137 is incorporated. However, instead of the heat insulating member 137, a foamed heat insulating material may be filled in the internal space of the partition body 122 including the suppressing portion 124. At this time, the foamed heat insulating material is filled in the internal space from the hole provided in the inner box 103 through the hole (not shown) provided in the partition 122.

And can be filled with foam insulation. For this reason, it is excellent in the heat insulation effect, and is particularly suitable when the temperature zones of the storage rooms partitioned by the heat insulation partition 150 are significantly different. Moreover, since the heat insulation partition part 150 is formed integrally with the inner box 103 formed by vacuum molding, the amount of material used can be suppressed.

  Further, by configuring only the front portion of the storage chamber with the partition 122, it is possible to attach the contact member 123 provided with the heat radiating pipe 131 on the back surface together with the suppressing portion 124 after the box body 101 is foamed. Workability can be improved.

  The partition 122 configured only in the front portion of the storage chamber is fixed with the heat insulating partition 150 and screws or the like. At this time, a gap may be generated between the components, and by attaching the seal member between the partition 122 and the heat insulating partition 150, it is possible to suppress the circulation of cool air from the gap.

  As described above, in the present embodiment, the partition 122 and the heat insulating partition 150 are used to partition the storage chambers of different temperature bodies, thereby exchanging heat between the cool air in the storage chamber and the contact member 123. By obtaining both the effect of suppressing and the high heat insulating effect of the heat insulating partition 150, the power consumption can be reduced.

  The upper and lower storage chambers that exist in different temperature zones are partitioned in a heat-insulated state by the partition 122 to stabilize the temperature inside the respective storage chambers. However, a slight gap is generated between the parts in the mounting portion between the partition 122 and the inner box 103. Through this gap, cold air leaks between the upper and lower storage chambers, making it difficult to exert the heat insulating effect of the partition 122. Moreover, depending on the case, it may become quality problems, such as the occurrence of frost due to cold air leakage.

  In the present invention, by providing the first restraining portion 160 that is a space without air convection between the attachment portion of the partition 122 and the inner box 103, a gap generated between the partition 122 and the inner box 103 is provided. It is possible to suppress the cool air passing up and down and to suppress the heat transfer. Further, by disposing a second suppression unit 161 different from the first suppression unit 160 closer to the outer box 102 than the first suppression unit 160, a plurality of spaces for suppressing the circulation of cold air may be provided. The heat transfer suppression effect can be improved. The first suppression unit 160 and the second suppression unit 161 are configured by ribs 162 of the upper partition plate 135.

  Further, the third suppressing portion 163 can form a space between the partition 122 and the inner box 103 due to the concave shape of the inner box 103, and can further suppress heat transfer. As described above, in the present embodiment, the upper side and the lower side of the partition 122 are each provided with the first suppression unit 160 and the second suppression unit in a double structure, and further the third suppression unit 163 is provided on the back side. By providing on the back side, heat transfer is reliably suppressed by providing a triple structure suppression part only on one storage chamber side.

  The communication space 165 in which the inner box hole 164 is opened in the inner box 103 located on the side surface and the back side of the joint between the partition 122 and the inner box 103 is filled with the foam heat insulating material 130 from the inner box hole 164. Since the sealing performance can be improved, the energy saving effect can be improved.

(Embodiment 5)
FIG. 14 is an enlarged cross-sectional view of the refrigerator in the fifth embodiment of the present invention.

In addition, although description is abbreviate | omitted about the part which can apply the structure similar to Embodiment 1-4 or the same technical idea, there is a malfunction by implementing this Embodiment in combination with the structure of the said Embodiment. As long as there is not, it is possible to apply in combination.

  As shown in FIG. 14, the partition 122 is constituted by a heat insulating member 137 between the upper partition plate 135 and the lower partition plate 136. The upper partition plate 135 includes a second restraining portion 161 that is a heat transfer restraining portion at an attachment portion with the inner box 103. The second suppressing portion 161 is configured between the upper partition plate 135 and the inner box 103. An inner box convex portion 166 is provided in the inner box 103 where the partition 122 and the inner box 103 are attached, and the gap with the upper partition plate 135 is partially reduced. Further, a fourth suppression portion 167 having functions of both a heat transfer suppression portion and a heat conduction suppression portion is formed on the storage compartment side of the upper partition plate 135. The inner box convex portion 166 is provided on both side surfaces and the back surface of the partition 122, and the fifth suppression portion 168 and the sixth suppression portion 169 are divided by the convex portion 166. The fourth suppressing portion 167 is substantially sealed only by the structure of the partition, and has a contact portion 167 a that is in surface contact with the inner box 103.

  Further, the second suppressing portion 161, the fourth suppressing portion 167, the fifth suppressing portion 168, the sixth suppressing portion 169, and the inner box convex portion are also located between the inner boxes 103 of the lower partition plate 136. It is provided in the same manner as the partition plate 135.

By providing convex portions formed in the inner box 103 on the both side surfaces and the back surface of the partition body in the mounting portion, it is possible to close the gap in the mounting portion and to block the flow of cold air. The fourth suppression portion 167 is formed by the upper partition plate 135, and the fourth suppression portion 167 is completely different from the second suppression portion 161 configured by the contact portion between the partition body 122 and the inner box 103. Since it is a separate space and is completely cut off from the storage room, it is a space without air convection, and the effect of suppressing heat transfer can be improved.

  In addition, the fourth restraining portion 167 has a contact portion 167a that is in surface contact with the inner box 103 and is provided on the storage chamber side. For example, the inner box molding shape with urethane foam of the inner box 103 is provided. Even if the internal space is displaced in the front-rear direction or the left-right direction due to variations in the air flow, it is possible to suppress the movement of the cold air because there is no air convection. Since there is no cold air intrusion into the suppression unit 167, heat transfer can be suppressed.

  Further, the fifth restraining portion 168 and the sixth restraining portion 169 are divided by the convex portion 166 of the inner box, so that the convex portion 166 is formed by the foaming pressure during the inner box molding with urethane foaming. Therefore, the sealing property of the fifth suppression unit 168 and the sixth suppression unit 169 can be further improved, and heat transfer can be suppressed.

  In the present embodiment, the inside of the fourth suppressing portion 167 is a closed space and is a hollow space, but a heat insulating material may be put inside, and in that case, the fourth suppressing portion 167 is further added. It goes without saying that the function as the heat conduction suppressing portion is improved because the heat insulation property of the material increases.
