Description

  The present invention relates to a cooking device, and more particularly, to a cooking device having a grill chamber in which a pullable grill door is installed.

  The heating cooker that is built into the system kitchen furniture or sink, or set on the kitchen cabinet, etc. is a heating means (induction heating coil, radiant heating type electricity) for heating the object to be heated placed on the upper surface. Heater, gas burner, etc.) and a grill heating chamber (electric heater, gas burner, etc. are installed) for heating an object to be heated inserted from the side. In the grill heating chamber, a tray for taking in and out the object to be heated (as another example, a placement net for placing fish etc. is also installed), and the tray and the grill door are integrated. Therefore, when the tray is pushed into the grill heating chamber, the grill heating chamber is sealed by the grill door. In addition, a handle is provided on the grill door to facilitate the tray insertion and removal.

Therefore, the cook can put a hand on the handle to put in and out the tray and close the grill heating chamber. In addition, outside air is sucked into the grill heating chamber, and smoke generated by heating is discharged from a predetermined exhaust port. Normally, the air is sucked from the side where the cook stands (the same in the front) and exhausted from the side far from the cook (the same in the rear).
Therefore, a technique is known in which a handle is provided with a vent so that the handle is not overheated by radiation or electric heat from the grill heating chamber, and the handle is cooled by air passing through the vent (see, for example, Patent Document 1). ).

Japanese Utility Model Publication No. 2-137610 (page 3-4, FIG. 2)

  However, although the invention disclosed in Patent Document 1 is devised to cool the handle so that the handle is not overheated by radiation or electric heat from the grill heating chamber, it does not prevent overheating of the grill door itself. . In particular, the grill door usually has a transparent window (view window) through which the inside of the heating chamber can be seen. Although this portion is covered with heat-resistant glass, it becomes hot due to the high heat of the grill heating chamber. Therefore, an adult cook may accidentally touch a grill door or transparent window that has been hot for a predetermined period of time after cooking or after cooking, or a child may touch it inadvertently. There was a risk of it.

  In view of the above, an object of the present invention is to provide a cooking device that prevents a hand or finger from touching a grill door or a transparent window.

A heating cooker according to the present invention comprises a grill heating chamber capable of storing an object to be heated, an openable grill door installed in front of the grill heating chamber, and a heating element for heating the grill heating chamber. A cooking device comprising:
A guard body is provided in front of the grill door.

  In the cooking device according to the present invention, since the front surface of the grill door is covered with the guard body, contact of a hand or a finger to the grill door or the transparent window that becomes high temperature is prevented. Therefore, the comfort at the time of cooking or installing in a kitchen etc. improves.

  The heating bodies 72a and 72b are both induction heating type heating bodies, and the heating body 72c at the rear center position is a radiation type electric heating body known as an induction heating type heating body or a radiant heater.

(Grill door)
3 to 6 schematically show a grill door in the heating cooker according to the embodiment of the present invention, and FIG. 3 (b) is a cross-sectional view in plan view, FIG. 4 is a perspective view seen obliquely from the rear to the front, FIG. 5 is a perspective view showing an air passage, and FIG. 6 (a) is a side view. FIG. 6B is a cross-sectional view of the central portion viewed from the side, and FIG. 6B is a cross-sectional view of the side portion viewed from the side.

(Grill door)
In FIG. 6, the grill door 40 connects the front plate 41 on the upper front side and the front plate 45 on the lower front side, the back plate 42 on the rear surface, the outer periphery of the front plate 41 and the front plate 45, and the outer periphery of the back plate 42. A box having an outer peripheral plate 43 to be operated.
The front plate 41 is made of heat-resistant glass having a rectangular outer periphery, and a transparent window 41w (indicated by double diagonal lines in FIG. 7) is formed. That is, an impermeable heat-resistant coating surface is formed on the entire back surface except the transparent window 41w, and only the transparent window 41w is not subjected to the heat-resistant coating, so that transparency is ensured. The lower end portion 41c of the front plate 41 is inserted into a vertical groove formed in the upper end portion of the front plate 45 and fixed by fixing means (not shown) such as screws.
The back plate 42 is made of metal having a rectangular outer periphery, and has an opening 42 w. The back plate 42 is arranged substantially parallel to the front plate 41 with a sealant 121 interposed therebetween. And the outer peripheral board 43 (substantially rectangular cylinder shape) integrally extended ahead from the outer periphery of the backplate 42, and the inner peripheral board 44 (substantially rectangular shape) integrally extended ahead from the opening part 42w (same as inner periphery). Tube-like).

  Furthermore, on the back surface (rear surface) of the transparent window 41w, a flat plate-shaped inner transparent window 120 (double hatched in FIG. 7) made of heat-resistant glass having a size covering the whole is installed. Yes. At this time, a frame-shaped sealing material 121 made of heat-resistant rubber or the like is disposed around the transparent window 41w of the front plate 41, and the transparent window 41w and the inner transparent window 120 face each other with the sealing material 121 interposed therebetween. A heat insulating layer S composed of a sealed air layer is formed between the opposing surfaces.

Since the front end surface of the inner peripheral plate 44 is in contact with the rear surface of the inner transparent window 120, it is held between the front plate 41 and the inner peripheral plate 44 in a state where the sealing material 121 and the inner transparent window 120 overlap each other. Has been.
Therefore, the front plate 41, the back plate 42, the U-shaped range of the upper portion of the outer peripheral plate 43, the upper side of the inner peripheral plate 44, and a part of the sealing material 121 and the inner transparent window 120 are surrounded. An upper door space 49U is formed. Further, it is surrounded by the front plate 45, the back plate 42, the U-shaped range of the lower portion of the outer peripheral plate 43, the lower side of the inner peripheral plate 44, and a part of the sealing material 121 and the inner transparent window 120. A lower door space 49L is formed.
That is, the grill door 40 is divided into two spaces, an upper door space 49U and a lower door space 49L.

(Vent hole)
In FIG. 3A, a handle 50 protruding forward is provided on the front surface of the front plate 45 of the grill door 40, and intake holes 45 a and 45 b penetrating to the side of the front plate 45 are formed. Yes. In FIG. 3, the intake holes 45a and 45b show six round holes, but the number and shape thereof are not limited thereto.
In FIG. 4, a side blow hole 46 and a central blow hole 47 are formed in the back plate 42 of the grill door 40 (this will be described in detail separately).

The term “side to the front plate 45” refers to a range that does not coincide with the position of the hand when the user places the hand 50 on the handle 50, for example, a central range in the width direction of the front plate 45. The portion excluding 100 to 150 mm indicates a range near the side edges 41 a and 41 b of the front plate 41.
Therefore, the handle 50 over the entire width of the front plate 41 as shown in FIG. 3 indicates a range near the side edges 41a and 41b, excluding about 100 to 150 mm which is the central range of the handle 50. Or when the handle 50 is installed in the range of about 100-150 mm which is the center range of the width direction of the surface board 41, the range near side edge 41a, 41b except the handle 50 is pointed out.

(Handle)
The handle 50 is installed over substantially the entire width of the front plate 45, and the end portions 50a and 50b of the handle 50 (the same as the end portions 52a and 52b of the handle portion 52) are respectively left and right of the front plate 45. Installed on both side edges (fixed with screws).
The handle 50 includes a flange portion 51 that extends substantially horizontally toward the front of the front plate 45, a handle portion 52 that is substantially parallel to the front plate 45 (exactly in an arch shape) and extends in the vertical direction, The rear wall 55 in contact with the front surface has a substantially h-shaped cross section in a side view formed integrally. Then, a pair of partition walls 53a and 53b that connect the handle portion 52 and the rear wall 55 are installed with a predetermined gap therebetween.
Further, an elongated slit 90 is formed at a corner portion where the flange portion 51 of the handle 50 and the rear wall 55 cross each other so as to penetrate the flange portion 51 vertically.

(Handle space)
Therefore, a central handle space 59c (substantially square pillar shape) is formed which is surrounded by the central portion of the handle portion 52 and the rear wall 55 and the pair of partition walls 53a and 53b and whose upper portion is covered by the central portion of the flange portion 51. Yes.
Further, a side handle space 59a (substantially right triangular prism shape) surrounded by the side portion of the handle portion 52 and the rear wall 55 and one partition wall 53a and covered with the side portion of the flange portion 51 in the upper part. Similarly, a side handle space 59b (which is surrounded by the side portion of the handle portion 52 and the rear wall 55 and the other partition wall 53b and is covered by the side portion of the flange portion 51 in the upper part is similarly formed. (Substantially right triangular prism shape) is formed.

(Through hole)
And the through-holes 56a and 56b are formed in the rear surface wall 55 in the side handle space 59a and 59b of substantially right triangular prism shape. With the handle 50 installed, the through holes 56a and 56b coincide with the intake holes 45a and 45b, respectively, and an air passage is formed by the through hole 56a and the intake hole 45a, respectively. It has come to be. That is, it becomes an intake passage that communicates with the lower door space 49L of the grill door 40. Accordingly, indoor air such as kitchen is sucked from the side handle spaces 59a and 59b into the lower door space 49L of the grill door 40 via the intake passage.

Further, the handle 50 cannot be directly recognized because the intake holes 45a and 45b are covered with the handle 52 in a front view.
And since it is an "arch shape" that gradually protrudes toward the front center in plan view, in the range close to the end portions 50a, 50b of the handle portion 52, the interval between the handle portion 52 and the rear wall 55 becomes narrow, It has become difficult for the user to place his / her fingers. That is, since the user's fingers do not enter the side handle spaces 59a and 59b, the intake holes 45a and 45b are not likely to be blocked during cooking. In the unlikely event that the pressure in the grill heating chamber 20 rises and the hot air flows backward, the intake holes 45a and the through holes 56a that communicate with each other, or the side handle spaces 59a from the intake holes 45b and the through holes 56b that communicate with each other. 59b, even when hot air flows out, since only the lower part is open, the hot air flows downward and the hot air does not touch the user's fingers (see FIG. 6B). ).

Further, since the central handle space 59c is formed by the partition walls 53a and 53b, it is more difficult for the user to hang his / her fingers to the side of the partition walls 53a and 53b or to move the fingers to the side. It has become.
The handle 50 has a substantially h-shaped cross section and is a box having an opening at the bottom, and thus has a large second moment of section. However, the rigidity of the handle 50 is increased by providing the partition walls 53a and 53b. It is getting bigger. Further, the handle 50 (including the partition wall 53) may be formed integrally with the front plate 45.

(Blowout hole)
In FIG. 4, penetrating side blowing holes 46 a and 46 b (hereinafter sometimes collectively referred to as “side blowing holes 46”) in the range near the side edges 42 a and 42 b of the back plate 42 of the grill door 40, A central blowout hole 47 is formed in the center area of the back plate 42.

  4 and 5, the side blow-out holes 46 are arranged “sideward” in the same manner as the intake holes 45 a and 45 b formed in the front plate 45, but they are in the vertical direction with respect to the intake holes 45 a and 45 b. The phase does not match (is shifted). Therefore, the intake air (air) that has passed through the through hole 56a and the intake hole 45a and the through hole 56b and the intake hole 45b does not directly enter the side blowout hole 46, but collides with the back plate 42 and the lower door. After filling the space 49L, the air is blown out from the side blow hole 46 and the central blow hole 47 to the grill heating chamber 20.

  At this time, since the opening area of the central blowing hole 47 is larger than the opening area of the side blowing hole 46, the blowing of intake air does not concentrate on the side blowing holes 46 close to the suction holes 45a and 45b. Therefore, since the amount of blowout from the central blowout hole 47 far from the intake holes 45a and 45b is secured, a relatively uniform wind flow is formed over the entire width of the grill heating chamber 20, and uniform cooling of the object to be heated. Is possible.

  Further, the passages of the through holes 56a and the intake holes 45a formed at the left and right end portions of the rear wall 55 and the passages of the through holes 56b and the intake holes 45b serve as an intake passage that leads from the outside of the grill door 40 to the door space 49. Therefore, since fresh indoor air becomes intake air and fills the lower door space 49L, the transparent window 41w and the handle 50 are cooled by the intake air.

  In addition, in FIG. 4, although the side blowing hole 46 and the center blowing hole 47 are each long holes, the shape, quantity, and arrangement | positioning range are not limited to this. For example, each may be constituted by a plurality of round holes. At this time, if the number of the round holes formed per unit area or the opening area (diameter of the round hole) is set closer or larger in the central blowing hole 47 than in the side blowing hole 46, grill heating is performed. A uniform wind flow over the entire width is formed in the chamber 20.

Moreover, you may form the side blowing hole 46 and the center blowing hole 47 over the full width of the backplate 42 (At this time, the boundary of the side blowing hole 46 and the center blowing hole 47 becomes unclear). At this time, if the opening area of the blowout holes (the diameter of a round hole) is increased as it approaches the center of the back plate 42 or the interval between the blowout holes is reduced as it approaches the center, the grill A uniform wind flow over the entire width is formed in the heating chamber 20.
Further, a guide plate (so-called “baffle plate”) or an orifice for guiding the wind flow may be formed in the lower door space 49L to make the flow of the blown air uniform.

(Seal packing)
In FIG. 4, a seal packing 48 is installed in a rectangular ring shape along the outer periphery of the back plate 42. When the grill door 40 is pushed rearward, the seal packing 48 comes into airtight contact with the periphery of the front opening 21 of the grill heating chamber, and air is supplied from a location other than the intake holes 45a and 45b. The cross section is a perfect circle, an ellipse, or a double circle.

(Guard body)
7 to 11 schematically illustrate a guard body attached to a grill door in a heating cooker according to an embodiment of the present invention, FIG. 7 is a front view, and FIG. 8 is a cross-sectional view in side view. FIG. 9 is a perspective view showing the attachment procedure, FIG. 10 is a perspective view showing the attached state, and FIG. 11 is a plan view showing the attached state.
7 to 11, the entire guard body 110 is formed of a metal wire. The guard body 110 includes a plurality of (for example, ten) horizontal bars 110a extending in front and parallel to each other at a predetermined (for example, 5 to 6 mm) facing interval, and left and right ends of the horizontal bars 110a. A plurality of vertically extending vertical bars 110b and a plurality of side bars 110c that are read at right and left ends of each horizontal bar 110a at right angles thereto and extend horizontally rearward. That is, each has a ladder shape in front view and side view.

(Guard leg front and back legs)
The pair of side bars 110c positioned on the uppermost side of the side bars 110c are connected by a connecting bar 110d, and the front leg 110e is connected to the horizontal bar 110a positioned on the lowermost side of the horizontal bars 110a. The rear leg 110 f is connected by the connecting piece 113.
That is, the front leg 110e is composed of a pair of vertical pieces 111e and one horizontal piece 112e, and has a U-shape when viewed from the front. The rear leg 110f is composed of a pair of vertical pieces 111f and one horizontal piece 112f, and has a U-shape when viewed from the front. The pair of left and right vertical pieces 111e and 111f are connected to each other by connecting pieces 113 at two upper and lower positions (the connecting pieces 113 are arranged on the left and right and up and down for a total of four pieces).

(Attaching the guard body)
The rear leg 110 f of the guard body 110 is inserted from above into the elongated slit 90 formed in the handle 50, and at this time, the front leg 110 e abuts on the front surface of the flange portion 51 of the handle 50. Accordingly, the guard body 110 is installed in such a manner that the flange portion 51 of the handle 50 is elastically sandwiched from the front and rear with the front legs 110e and the rear legs 110f.
Thereby, the guard body 110 can be fixed to the front position of the grill door 40 by pushing the rear leg 110f into the slit 90 without using a screw or the like.
At this time, the connecting piece 113 is in contact with the upper surface of the flange portion 51 of the handle 50, and serves as a “positioning stopper” when the rear leg 110f of the guard body 110 is inserted upward into the slit 90. Therefore, if the guard body 110 is inserted into the slit 90 to the dead end, it will be in a predetermined position, and as will be described later, the entire front surface of the transparent window 41w of the grill door 40 is covered with a predetermined interval.

Further, the horizontal bar 110a, the vertical bar 110b, and the side bar 110c are not separately connected to each other with a single wire, but are cut at a predetermined length, for example, the right and left ends of the horizontal bar 110a are bent at right angles. Alternatively, the horizontal bar 110a and the side bar 110c may be integrated into a single wire that is bent in a U shape.
Further, the front leg 110e is connected not only to the lowermost horizontal bar 110a but also to a plurality or all of the horizontal bars 110a, and the rear leg 110f is extended upward to be connected to the connecting bar 110d, whereby the entire guard body 110 is connected. The strength (particularly, the rigidity of the front legs 110e and the rear legs 110f) may be further increased.
In the figure, reference numeral 110g denotes a bent portion that is continuous with adjacent side bars 110c by bending the rear end of one side bar 110c into a U shape.

The guard body 110 has a predetermined distance (for example, about 5 to 6 mm) between the plurality (for example, 10) of horizontal bars 110a as described above, and a user's finger is inserted between them from the front. I can't do it.
The guard body 110 is formed in a size that covers the entire front surface of the transparent window 41w of the grill door 40 with a predetermined interval in a state where the guard body 110 is attached to the front position of the grill door 40. Therefore, even if the transparent window 41w is heated to a high temperature inside the grill heating chamber 20 (up to 350 ° C. at the maximum), it is possible to prevent the user from inadvertently contacting the high temperature portion. it can.
Further, since the guard body 110 has a small contact area with the front plate 45 and the front plate 41 of the grill door 40, even if the front plate 45 and the front plate 41 are heated by the heat from the grill heating chamber 20, The temperature of the guard body 110 itself can be kept relatively low (for example, the temperature of the horizontal bar 110a is 50 ° C. or less even when the grill heating chamber 20 is at 300 ° C.).

(Grill door variations)
As described above, in order to facilitate understanding, the grill door 40 is described as being formed by the front plate 41, the back plate 42, the front plate 45, and the like, and the handle 50 is installed (connected) to the front plate 45. Such constituent members (same as constituent parts) may be obtained by connecting separate members to each other or by molding a single plate material. For example, the back plate 42, the outer peripheral plate 43, and the inner peripheral plate 44 may be integrally molded (for example, press molding or casting).

(Variation of heating element)
Further, as a part of the plurality of heating bodies 72 (see FIG. 2), a coil through which a high-frequency current flows and which heats an object to be heated by electromagnetic induction is shown, but the present invention is limited to this. It is not a thing, and this is not essential. For example, one heating body 72 may be an electric heater, a gas burner, or the like. At this time, the top plate 70 is removed according to the type of the heating body, and the types of the power switches 73 and 74 are changed. Alternatively, cooking may be performed only in the grill heating chamber 20, and the top surface may not be provided with heating means.
Further, the grill heating chamber 20 is shown in which an upper heater 23 and a lower heater 24 are arranged, but the present invention is not limited to this. For example, only one of the upper heater 23 and the lower heater 24 may be disposed. The upper heater 23 and the lower heater 24 may be a heating element (such as a nichrome wire or a halogen heater) by energization or a gas burner.

FIG. 12 is a cross-sectional view schematically showing a grill door in a heating cooker according to another embodiment of the present invention. As shown in FIG. 12, this embodiment is characterized in that the rear wall 55 of the handle portion 52 of the grill door 40 is deleted.
That is, the handle portion 52 is fixed to the front plate 45 via the flange portion 51 and the partition walls 53a and 53b. According to this, the weight of the grill door 40 can be reduced by deleting the rear wall 55, and the configuration can be further simplified, so that the assemblability is improved.

In addition, it is formed between the transparent window 41w (shown with double diagonal lines in FIG. 12) of the grill door 40 and the inner transparent window 120 (shown with double diagonal lines in FIG. 12) covering the transparent window 41w. The air introduced from the outside of the grill door 40 may be circulated through the lower door space 49L through the heat insulating layer S.
Specifically, if indoor fresh air is introduced into the passage from the outside of the grill door 40 through the intake holes 45a and 45b to the lower door space 49L by natural intake or forced intake by a fan, The temperature rise of the heat insulation layer S is suppressed by the intake air flow, and the transparent window 41w and the handle 50 are cooled more effectively.

  Further, the guard body 110 itself is formed of a material having low thermal conductivity (for example, plastic), or even if the guard body is made of metal, the main surface of the guard body 110 is entirely covered with a material having low thermal conductivity. (For example, including coating with a coating), or by raising the surface of fine fibers to reduce the temperature sensation when touched by the user, comfort and security of using the cooker It is also possible to increase the feeling.
