[Industrial applications]

 This invention relates to a heated toilet seat to be attached to a Western-style toilet.

[0002]

[Prior Art]

 Generally, a western-style toilet is attached with an O-type or U-type toilet seat. On the other hand, during cold seasons such as winter, the toilet seat is cold, which makes it difficult to sit down and is uncomfortable during defecation. Therefore, recently, toilet seats with a built-in heater and a heating function have been developed and are on the market. Such a heated toilet seat is, for example, as shown in FIG. 5, a heater (not shown) provided in the toilet seat 11 is turned on / off by a control switch 12 provided outside. The control switch 12 switches the heating temperature between a low temperature and a high temperature.

[0003]

[Problems to be solved by the device]

 However, the heated toilet seat has a problem that it cannot be confirmed whether the toilet seat 11 is in a warm state without touching it with a hand or the like. In addition, it is difficult to tell whether the heating temperature is low or high, so there is a problem of low-temperature burns if used for a long time without knowing the heating temperature. Further, the control switch 12 has a small portion showing ON / OFF, and the operation of checking the state of the switch becomes complicated, so that the user sometimes forgets to turn off the switch when going out.

The present invention has been made in view of such circumstances, and provides a heating toilet seat capable of confirming the on / off state of the heating function and how much the heating temperature has risen by visually observing the toilet seat. Is its purpose.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the heating toilet seat of the present invention is a toilet seat that is attached to a western-style toilet and has a heating function, and at least a part of its surface is formed in a temperature-sensitive discoloration area. When the area is heated by the heating function, the color tone changes from that at room temperature.

[0006]

[Action]

 That is, the heating toilet seat of the present invention is equipped with a heating function to warm the surface so that the skin does not feel cold even when it is directly touched when sitting. Then, when the toilet seat becomes warm, the temperature-sensitive discoloration area formed on at least a part of its surface changes to a color tone different from that at normal temperature, and it is notified that the toilet seat has warmed to an appropriate temperature. ing. For this reason, the warmth of the toilet seat and the on / off state of the heating function can be known at a glance, and low-temperature burns and forgetting to turn off the switch do not occur.

Next, this invention will be described in detail.

The heated toilet seat of the present invention is equipped with a heating function, and is formed by forming a temperature-sensitive discoloration area on at least a part of the surface thereof.

As the heating function, a conventionally known function such as a planar heater or a heater wire in which a heater circuit is sandwiched with a resin film or a resin sheet is used.

The above-described toilet seat is molded using a conventionally known resin that has heat resistance even when heated by a heater or the like, and has durability against the load of the human body. Examples of such a molding resin material include ABS (acrylonitrile-butadiene-styrene) resin, polystyrene resin, polypropylene resin and the like, which may be used alone or in combination.

Further, the temperature-sensitive color-changing region formed on at least a part of the surface of the toilet seat uses a temperature-sensitive color-changing ink that changes to a color tone different from that at room temperature when heated by a heating function. It is formed. Such a thermosensitive color-changing ink is not particularly limited, and a conventionally known thermosensitive color-changing ink can be used as it is. However, since the temperature range where the skin feels warm to the touch is about 38 to 40 ° C, it is preferable that the temperature changes to a color tone different from that at room temperature when the temperature exceeds 38 ° C. In particular, the temperature-sensitive color-changing ink that is hermetically contained in microcapsules made of epoxy-based resin, urea-based resin, etc., has a clear color tone and has excellent durability, as the temperature-sensitive color changes inside the ink. preferable.

The temperature-sensitive color-changing region is formed on the entire toilet seat by, for example, mixing the temperature-sensitive color-changing ink with a predetermined amount of the resin material for molding the toilet seat and kneading the mixture. In addition, a printed image is printed on a predetermined portion of the surface of the toilet seat with the above-mentioned temperature-sensitive color-changing ink to form a part or the entire surface of the toilet seat.

Two types of ink are used, a temperature-sensitive color-changing ink whose predetermined color tone changes when it exceeds 38 ° C. and a temperature-sensitive color-changing ink whose predetermined color tone changes when it exceeds 40 ° C. It is also possible to form a temperature sensitive color change area. By forming temperature-sensitive color-change regions in different temperature zones on the toilet seat in this way, the warmth (weak temperature / high temperature) of the toilet seat is notified by the change in color tone.

Next, examples will be described.
