Description

  Aspects of the invention generally relate to a heated toilet seat apparatus.

  In order to suppress power consumption, an instantaneous heating toilet seat device that waits at a low temperature when not in use and warms a seating surface in a short time when in use is known. In the instant heating toilet seat device, the toilet seat is warmed in a short time with electric power larger than usual, so that the temperature of the seating surface may become abnormal before the safety device is turned off. Therefore, in the instantaneous heating toilet seat device, it is necessary to provide a safety device that reliably shuts off the power supply before the temperature of the seating surface becomes abnormal.

On the other hand, there is a heated toilet seat having a region of a temperature measuring unit in which a part of a cord-like heating element is meandered closely to increase the linear density (Patent Document 1). In the temperature measuring part of the heating toilet seat described in Patent Literature 1, a safety device that shuts off the power supply when an abnormal temperature is reached is installed via a lower foil body.
However, in the structure like the heating toilet seat described in Patent Document 1, the installation pattern of the heating elements is limited, and it is difficult to perform a flexible design as the design concept of the safety device.

A first adhesive 237 is provided between the second foil body 232 and the cord-like heating element 235 and between the first foil body 231 and the second foil body 232. The first adhesive 237 joins the second foil body 232 and the cord-like heating element 235. The first adhesive 237 joins the first foil body 231 and the second foil body 232. Thus, the cord-like heating element 235 is bonded and sandwiched between the first foil body 231 and the second foil body 232.

  A second adhesive 238 is provided between the first foil body 231 and the inner surface 223 of the toilet seat upper plate 220. The second adhesive 238 joins the first foil body 231 and the inner surface 223 of the toilet seat upper plate 220. Accordingly, the heating element body 230 is installed on the inner surface 223 of the toilet seat upper plate 220.

  Each of the first foil body 231 and the second foil body 232 is a metal foil. The thermal conductivity of the metal foil is higher than the thermal conductivity of the toilet seat upper plate 220. Examples of the first foil body 231 include an aluminum foil and a copper foil. Examples of the second foil body 232 include an aluminum foil and a copper foil.

  As shown in FIG. 3, the cord-like heating element 235 meanders between the first foil body 231 and the second foil body 232, and the entire first foil body 231 and the second foil body 232. It is arranged over. Further, as shown in FIG. 1, the heating element body 230 is provided over the entire seating surface 221 on the inner surface 223 of the toilet seat upper plate 220. Therefore, the cord-like heating element 235 meanders under the seating surface 221 and is disposed over the entire seating surface 221. The arrangement pattern of the cord-like heating elements 235 is not limited to the example shown in FIG. 3, and may be arranged in a spiral shape, for example.

  As shown in FIG. 5A and FIG. 5B, the temperature measuring unit 240 of the present embodiment includes a first foil body 241, a second foil body 242, and a cord-like heating element 245 (second Cord-like heating element). The cord-like heating element 245 is provided between the first foil body 241 and the second foil body 242. As the first foil body 241 and the second foil body 242 are bent as indicated by the arrows A1 and A2 shown in FIG. 5A, the safety device 250 has the first foil body 241 and the second foil body 242 folded. The foil body 242 is interposed.

  As shown in FIG. 5B, the first foil body 242 and the cord-like heating element 245, and between the first foil body 241 and the second foil body 242, An adhesive 247 is provided. The first adhesive 247 joins the second foil body 242 and the cord-like heating element 245 together. The first adhesive 247 joins the first foil body 241 and the second foil body 242. Thus, the cord-like heating element 245 is bonded and sandwiched between the first foil body 241 and the second foil body 242.

  A second adhesive 248 is provided between the first foil body 241 and the safety device 250 and between the first foil bodies 241 facing each other. The second adhesive 248 joins the first foil body 241 and the safety device 250. The second adhesive 248 joins the first foil bodies 241 facing each other.

The third adhesive 246 joins the second foil body 242 and the inner surface 223 of the toilet seat upper plate 220. That is, the third adhesive 246 corresponds to the second adhesive 238 described above with reference to FIG.

  Each of the first foil body 241 and the second foil body 242 is a metal foil. The thermal conductivity of the metal foil included in the temperature detector 240 is higher than the thermal conductivity of the metal foil included in the heating element body 230. Examples of the metal foil included in the temperature measuring unit 240 include an aluminum foil and a copper foil. For example, the metal foil included in the temperature detector 240 is a copper foil, and the metal foil included in the heating element body 230 is an aluminum foil. Note that the metal foils of the first foil body 241 and the second foil body 242 may be the same material.

  As shown in FIG. 5A, the cord-like heating element 245 is disposed over both sides of the bent portion 249 of the temperature detecting unit 240. A cord-like heating element 245 is provided in a spiral shape on each side of the bent portion 249 of the temperature detector 240. The linear density of the cord-like heating element 245 of the temperature measuring unit 240 is higher than the linear density of the cord-like heating element 235 of the heating element body 230. Note that the arrangement pattern of the cord-like heating elements 245 is not limited to the example shown in FIGS. 5 (a) and 5 (b). Details of other arrangement patterns of the cord-like heating element 245 will be described later.

  The cord-like heating element 235 included in the heating element body 230 is the same as the cord-like heating element 245 included in the temperature measuring unit 240. For this reason, in the present embodiment, the cord-like heating element 235 included in the heating element body 230 will be described as an example.

As shown in FIG. 6, the cord-like heating element 235 of the present embodiment includes a heater core wire 235a, a heating wire 235b, an insulator 235c, and a fusion material 235d.
The heater core wire 235a includes, for example, an aramid fiber. The diameter of the heater core wire 235a is, for example, about 0.14 millimeter (mm).
The heating wire 235b is wound around the heater core wire 235a. The heating wire 235b includes, for example, a copper alloy and an abdominal portion that covers the copper alloy. The copper alloy may contain tin. The stomach portion has, for example, polyurethane. The diameter of the heating wire 235b is, for example, about 0.08 mm.

The insulator 235c covers the heater core wire 235a and the heating wire 235b. The insulator 235c includes, for example, a fluororesin. The outer diameter of the insulator 235c is, for example, about 0.4 mm.
The fusing material 235d covers the insulator 235c. The fusing material 235d has a thermoplastic resin. The fusing material 235d has, for example, a polyester elastomer.

  The control unit 410 transmits a control signal and supplies power to the cord-like heating element 235 of the heating element body 230. Then, the cord-like heat generating body 235 of the heat generating body main body 230 can warm the seating surface 221 of the toilet seat 200 by generating heat when energized. That is, the cord-like heating element 235 of the heating element body 230 generates heat that is transmitted to the seating surface 221 of the toilet seat upper plate 220.

  As shown in FIG. 4, the heating element main body 230 is provided on the back surface (inner surface 223) of the seating surface 221. The heat generated in the cord-like heating element 235 of the heating element body 230 spreads over the entire seating surface 221 via at least one of the first foil body 231 and the second foil body 232. Therefore, the conductivity (thermal conductivity) of heat transmitted from the cord-like heating element 235 of the heating element body 230 to the seating surface 221 via at least one of the first foil body 231 and the second foil body 232 is compared. High. Therefore, the toilet seat upper plate 220 can be heated immediately, and the seating surface 221 can be heated immediately. Thereby, an immediate warming effect can be heightened.

  In addition, the control unit 410 transmits a control signal and supplies power to the cord-like heating element 245 of the temperature detection unit 240. Then, the cord-like heating element 245 of the temperature measuring unit 240 is energized and generates heat. The heat generated in the cord-like heating element 245 of the temperature measuring unit 240 is transmitted to the safety device 250 via at least one of the first foil body 241 and the second foil body 242.

  The heating toilet seat device 100 with the immediate warming effect enhanced warms the seating surface 221 in a relatively short time. Therefore, the safety device 250 needs to detect the abnormal temperature of the temperature measuring unit 240 before the temperature of the seating surface 221 becomes abnormal, and to reliably shut off the power supply. As described above, the linear density of the cord-like heating element 245 of the temperature measuring unit 240 is higher than the linear density of the cord-like heating element 235 of the heating element body 230. Therefore, the temperature of the safety device 250 heated by the cord-like heating element 245 of the temperature measuring unit 240 becomes higher than the temperature of the seating surface 221 heated by the cord-like heating element 235 of the heating element body 230. Further, the thermal conductivity of the metal foil included in the temperature measuring unit 240 is higher than the thermal conductivity of the metal foil included in the heating element body 230. Therefore, the speed at which the heat generated in the cord-like heating element 245 of the temperature measuring unit 240 is transmitted to the safety device 250 is faster than the speed at which the heat generated in the cord-like heating element 235 of the heating element body 230 is transmitted to the seating surface 221. Thereby, the safety device 250 can detect the abnormal temperature of the temperature detection unit 240 before the temperature of the seating surface 221 becomes abnormal, and can reliably shut off the power supply.

  Here, since the safety device 250 is provided in the temperature measuring unit 240, when the temperature measuring unit 240 is formed as a part of the heating element main body 230, the cord-like heating element 235 of the heating element main body 230 is arranged. The arrangement pattern may be restricted. Then, regarding the safety device 250, it may be difficult to make a flexible design.

  On the other hand, according to the present embodiment, the temperature measuring unit 240 is provided separately from the heating element main body 230. Therefore, the control unit 410 can control the operation of the heating element body 230 and the operation of the temperature detection unit 240 independently of each other. Moreover, the heat generating body main body 230 and the temperature detection part 240 can be arrange | positioned mutually independently. Thereby, according to the characteristic of the safety device 250, the temperature measuring unit 240 can be configured flexibly. That is, the safety device 250 can be designed flexibly.

  As shown in FIG. 1, when the temperature measuring unit 240 is provided on the inner surface 223 of the toilet seat upper plate 220 so as to be separated from the heating element body 230, the temperature measuring unit 240 is securely attached to the inner surface 223 of the toilet seat upper plate 220. It can be arranged. Further, a part of the heat generated in the cord-like heating element 245 of the temperature measuring unit 240 can be transmitted to the seating surface 221. Thereby, the energy saving of heat | fever can be implement | achieved.

  When the temperature detecting unit is provided on the inner surface of the main body 400 and is not provided on the inner surface 223 of the toilet seat upper plate 220 as in the two-dot chain line temperature measuring unit 240a shown in FIG. 1, the heating element main body 230 is seated. Surface 221 can be heated. Therefore, the seating surface 221 can be heated more stably.

  When the metal foil included in the temperature measuring unit 240 is a copper foil and the metal foil included in the heating element body 230 is an aluminum foil, the thermal conductivity of the copper foil is higher than the thermal conductivity of the aluminum foil. Therefore, the heat generated in the cord-like heating element 245 of the temperature detecting unit 240 is transmitted to the safety device 250 earlier than in the case where the heat generated in the cord-like heating element 235 of the heating element body 230 is transmitted to the seating surface 221. . As a result, the safety device 250 can be reliably operated and the power supply can be reliably shut off.

  In addition, when the metal foil which the temperature detection part 240 has is copper foil, and the metal foil which the heat generating body main body 230 has is aluminum foil, the linear density of the cord-shaped heat generating body 245 of the temperature detecting part 240 is the heating element main body 230. It may be lower than the linear density of the cord-like heating element 235. In this case, since the thermal conductivity of the copper foil is higher than the thermal conductivity of the aluminum foil, the degree of freedom in design of the cord-like heating element 235 of the heating element body 230 and the cord-like heating element 245 of the temperature measuring unit 240, respectively. Becomes higher.

FIG. 7A is a schematic perspective view illustrating another temperature detection unit of the present embodiment. FIG. 7B is a schematic plan view illustrating another temperature detection unit of the present embodiment.

  The temperature measuring unit 240b shown in FIG. 7 includes a first foil body 241 and a cord-like heating element 245. The first foil body 241 covers the outer periphery of the safety device 250. In other words, the safety device 250 is provided inside the first foil body 241 and is covered with the first foil body 241 on the outside. The cord-like heating element 245 is wound around the outside of the first foil body 241.

  The heat generated in the cord-like heating element 245 of the temperature measuring unit 240 is transmitted to the safety device 250 via the first foil body 241. The material of the first foil body 241 and the thermal conductivity of the first foil body 241 are as described above with reference to FIGS. The linear density of the cord-like heating element 245 of the temperature measuring unit 240 is higher than the linear density of the cord-like heating element 235 of the heating element body 230.

  According to this, the temperature detector 240 can be reduced in size, and the degree of freedom in designing the temperature detector 240 can be further increased. Moreover, the same effect as the effect mentioned above regarding FIGS. 3-6 is acquired.
