JP 2002-364035 A Tomi No.3052344

  However, in the device described in Patent Document 1, in addition to the water temperature sensor and the LED, a control device, a power source, or a wiring for connecting the control device, the water temperature sensor, and the LED are necessary, and the configuration of the device is complicated. There is also a problem that, as a result, the apparatus becomes expensive.

  In addition, since it is necessary to install components such as temperature sensors and LEDs in the piping before piping, it is not easy to mount, and the device cannot be easily mounted after piping. .

  Further, in the water guiding device described in Patent Document 2, a part of the water guiding tube is integrally manufactured with a material in which water-soluble liquid crystal ink or thermochromic ink (registered trademark) is mixed with a plastic raw material, or one of metal water guiding devices. Since the portion is covered with the material, since the hot water directly touches the ink component, depending on the ink component, the human body may be affected.

  In addition, when a fluid other than warm water is flowed, the fluid directly touches the ink component, so depending on the ink component, the ink component may be dissolved, and in this case, the temperature of the fluid cannot be displayed. There is a possibility.

  The present invention has been made in view of these problems, and an object of the present invention is to provide a water guide device with a temperature display function that is safe with a simple structure for the temperature of a fluid flowing inside a pipe.

  The invention according to claim 1, which has been made to solve such a problem, is a water guiding device (1) having a temperature display function that is attached to a pipe (80) and displays the temperature of a fluid flowing in the pipe (80). The first member (10), the temperature sensitive material (30), the second member (20), and the sealing means (50, 52, 60) are provided.

  The first member (10) seals the fluid flowing in the pipe (80) directly so that the fluid does not leak to the outside of the pipe (80), and the temperature sensitive material (30) includes the first member (10). ) Is arranged on at least a part of the surface opposite to the surface in contact with the fluid, and changes depending on the temperature. Moreover, the 2nd member (20) is arrange | positioned on the surface opposite to the surface which the fluid of the 1st member (10) directly contacts, and it is comprised so that the temperature sensitive material (30) can be visually recognized.

  When the fluid in the pipe (80) leaks from the first member (10), the sealing means (50, 52, 60) penetrates between the first member (10) and the second member (20). It is mounted between the first member (10) and the second member (20).

According to such a water guiding device (1) with a temperature display function, the temperature of the fluid flowing in the pipe (80) can be easily and safely confirmed. This will be described below.
The first member (10) is in direct contact with the fluid flowing in the pipe (80). Therefore, if the temperature of the fluid in the pipe (80) changes, the temperature of the first member (10) changes. Then, the color of the temperature sensitive material (30) arranged on the surface opposite to the surface in contact with the fluid of the first member (10) changes.

  Here, the 2nd member (20) is arrange | positioned on the surface side opposite to the surface which the fluid of 1st member (10) directly contacts, and also it comprises so that a temperature sensitive material (30) can be visually recognized. Has been. Therefore, the changed color of the temperature sensitive material (30) can be visually recognized from the outside.

  That is, a light-emitting element such as an LED, a control device, or a wiring component is not required, and the temperature-sensitive material (30) is disposed on the surface opposite to the surface of the first member (10) that is in direct contact with the fluid. With the simple structure of covering with (20), the temperature of the fluid flowing in the pipe (80) can be confirmed.

  Further, the sealing means (50, 52, 60) prevents fluid from penetrating between the first member (10) and the second member (20). Therefore, during use of the water guiding device (1) with a temperature display function, the fluid permeates between the first member (10) and the second member (20), wets the temperature sensitive material (30), and erodes. Therefore, the component of the temperature sensitive material (30) does not melt into the fluid and flows out to the outside.

  Therefore, for example, when the fluid flowing in the pipe (80) such as a kitchen or a shower is warm water, the component of the temperature sensitive material (30) does not flow out of the kitchen or bathroom, so the component of the temperature sensitive material (30) Regardless of this, it can be safe without adversely affecting the human body.

  Further, since the temperature sensitive material (30) is not wetted or eroded by the fluid, it is possible to prevent the temperature sensitive material (30) from deteriorating. Therefore, the lifetime of the temperature sensitive material (30) can be kept long.

  Further, since the temperature sensitive material (30) is sealed between the first member (10) and the second member (20) by the sealing means (50, 52, 60), the sealing means (50, 52, 60). ) Is an elastic body such as packing, the first member 10) and the second member (20) can be easily separated, so that the temperature sensitive material (30) can be easily replaced.

  For example, since the outside air temperature changes depending on the season, change to a temperature-sensitive material (30) with a different sensitivity range according to the season, and change the color of the same color to the temperature change of the fluid regardless of the season. Can do. In addition, since the outside air temperature has a large regional difference, it can be replaced with a temperature sensitive material (30) having a different sensitivity range according to the region.

  Furthermore, since the temperature sensitive material (30) can be easily replaced, for example, if the water guiding device (1) with a temperature display function is applied to a shower head, a mixing faucet, or the like used in a bathtub or a washroom. The user can also enjoy by exchanging the temperature sensitive material (30) with various colors and sensitivities according to the mood.

  Note that “disposing the temperature-sensitive material (30) on the surface opposite to the surface of the first member (10) in direct contact with the fluid” means, for example, that the temperature-sensitive material (30) formed in a tape shape is the first member. It means to wrap around the outer surface of (10) or to apply or spray a paint-like temperature sensitive material (30) on the outer surface of the first member (10).

  Further, in this column, in order to facilitate understanding of the invention, the reference numerals used in the “Mode for Carrying Out the Invention” column are attached as necessary, which means that the scope of claims is limited by this reference numeral. Not what you want.

  Thus, when the first member (10) and the second member (20) are formed in a cylindrical shape, for example, the first member (10) and the second member (20) may be attached to the tip of a water discharge port such as a shower head or a mixing plug. It is also easy to attach to a joint.

  In addition, since it can be attached to a water outlet such as a shower head or a mixer tap or as a joint of a pipe (80), it can be easily attached to a pipe (80) or a shower head already installed. be able to.

Further, since the pipe (80) is usually a standard product such as JIS standard, the first member (10) and the second member (20) can be easily manufactured to conform to the standard.
By the way, various materials can be considered for forming the second member (outer cylinder) (20). As described in claim 2 , when the whole is formed of a transparent resin material, Since it is easy to visually recognize the temperature sensitive material (30) provided on the surface of the member (inner cylinder) (10), the user can easily and accurately visually recognize the temperature change.

Moreover, since the resin material is easy to process, the decorativeness of the instrument can be enhanced by decorative processing or the like.
Furthermore, since the thermal conductivity of the resin material is lower than that of the metal material, a high-temperature fluid is in contact with the first member (10), or a high-temperature fluid is flowing inside the inner cylinder (10). In addition, by using the second member (outer cylinder) (20) as a resin material, it is possible to give a thermal insulation effect to the appliance and to avoid dangers such as burns.

Further, as described in claim 3 , the second member (outer cylinder) (20) is made of a resin that allows the temperature-sensitive material (30) on the outer surface of the first member (inner cylinder) (10) to be visually recognized. The second member (outer cylinder) (20) is reinforced by the metal portion when the window portion (24) and the metal fitting portion (20) formed of metal other than the window portion (24) are formed. Therefore, the strength of the water guiding device with temperature display is increased.

  Also, depending on the type of fluid flowing in the pipe (80), the resin may be deteriorated. Even in such a case, for example, if the portion that directly contacts the fluid is made of metal, the resin is protected. Therefore, it can be used regardless of the type of fluid.

Further, as described in claim 4 , when the first member (inner cylinder) (10) is made of metal, the thermal conductivity is higher than that of other materials such as plastic and rubber. Since the temperature change of the flowing fluid is transmitted to the temperature sensitive material (30) quickly, the temperature change of the fluid can be recognized more quickly.

Further, when the first member (inner cylinder) (10) is formed of a ceramic material as described in claim 5 , the metal first member (inner cylinder) (although the thermal conductivity is inferior to that of metal) Since it can be made lighter than 10), a water guide device (1) with a temperature display function that is easy to handle can be obtained.

Attach to the spout of the mixer tap 5 or the faucet 7. At this time, the water outlet of the mixer tap 5 and the faucet 7 is brought into contact with the packing 52 attached to the flange portion of the inner cylinder 10, and the screw inside the metal fitting 22 is screwed into the screw of the water outlet.

(Characteristics of water guiding device 1 with temperature display function)
In the water guiding device 1 with the temperature display function as described above, the hot water flowing in the pipe 80 flows into the inner cylinder 10, and the temperature of the wall surface of the inner cylinder 10 changes depending on the temperature of the fluid that has flowed in. Then, the color of the temperature-sensitive seal 30 disposed on the outer surface of the inner cylinder 10 changes.

Moreover, the metal fitting part 22 and the window part 24 of the outer cylinder 20 are attached to the outer side of the inner cylinder 10, and the temperature-sensitive seal 30 on the outer surface of the inner cylinder 10 can be visually recognized by the window part 24.
That is, a light-emitting element such as an LED, a control device, or wiring components are not required, and the piping 80 has a simple structure in which the temperature-sensitive seal 30 is disposed on the outer surface of the inner cylinder 10 and covered with the outer cylinder 20. The temperature of the hot water flowing inside can be confirmed.

  Further, the packing 50, 52 and the O-ring 60 prevent warm water from penetrating between the inner cylinder 10 and the outer cylinder 20. Accordingly, since the hot water does not permeate between the inner cylinder 10 and the outer cylinder 20 and does not wet the temperature-sensitive seal 30 during use of the water guiding device 1 with a temperature display function, the components of the temperature-sensitive seal 30 are dissolved in the fluid. It does not flow out to the outside.

In other words, since the components of the temperature-sensitive seal 30 do not flow out into the kitchen or bathroom, regardless of the components of the temperature-sensitive seal 30, it can be safe without adversely affecting the human body.
Moreover, since the temperature-sensitive seal 30 can be prevented from being deteriorated by being wet with hot water, the life of the temperature-sensitive seal 30 can be kept long.

Strength increases as a water guide with temperature display.

  Furthermore, since the inner cylinder 10 is made of metal, it has a higher thermal conductivity than other materials such as plastic and rubber. Therefore, since the temperature change of the hot water flowing through the inside is transmitted to the temperature-sensitive seal 30 quickly, the temperature change of the hot water can be recognized earlier.

Further, the inner cylinder 10 is formed with a taper of φ16 mm to φ5 from the outer side in the axial direction to the inner side at a thickness of 3 mm from the end where the flange is formed. That is, since the water conveyance part is wide and the water discharge part is narrow, a water-saving effect can also be obtained.

That is, the metal fitting part 22 and the window part 24 of the outer cylinder 20 in the water guiding device 1 of the first embodiment are integrally formed of a transparent resin, and the O-ring 60 is not necessary.

  Thus, if the whole is formed of a transparent resin material, the temperature-sensitive seal 30 provided on the outer surface of the inner cylinder 10 can be easily viewed, so that the user can easily and accurately visually recognize the temperature change. It is possible.

Moreover, since the resin material is easy to process, the decorativeness of the instrument can be enhanced by decorative processing or the like.
Furthermore, since the resin material has a lower thermal conductivity than the metal material, even if a fluid having a high temperature flows in the inner cylinder 10, the outer cylinder 70 can be made of a resin material to give a heat insulating effect to the instrument. Yes, you can avoid the risk of burns.
