The upper case 130 may further include one or a plurality of second grooves 133 positioned adjacent to the first groove 132. The one or more second grooves 133 may have a desiccant therein. Accordingly, the upper case 130 may prevent the main heating heater 120 from malfunctioning due to moisture or moisture.

The lower case 140 may be coupled to a lower portion of the upper case 130. That is, the lower case 140 may be located under the metal case 110. Accordingly, the lower surface of the lower case 140 may be in contact with the left toilet. The lower case 140 may have a convex shape in a direction opposite to the upper case 130. That is, the lower case 140 may have a convex shape toward the lower side. Accordingly, a hollow portion 105 may be formed between the upper case 130 and the lower case 140.

The lower case 140 may be formed of a synthetic resin. The lower case 140 may be made of the same material as the upper case 130. Accordingly, the upper case 130 and the lower case 140 may be coupled through a vacuum fusion method.

One or more elastic bodies 142 may be coupled to the lower case 140. The one or more elastic bodies 142 may be rubbers. The lower case 140 may include one or more third grooves 141 on which the one or more elastic bodies 142 are seated.

The toilet seat 100 for the bidet according to the first embodiment of the present invention may further include a temperature sensing unit 300 for detecting the surface temperature of the metal case 110. The temperature sensing unit 300 may be electrically connected to the control unit 31 of the function control unit 30. Accordingly, the toilet seat 100 for the bidet according to the first embodiment of the present invention can efficiently control the surface temperature of the metal case 110.

The temperature sensor 310 may detect the surface temperature of the metal case 110. The temperature sensor 310 may be a thermistor element whose resistance value varies according to temperature. The temperature sensor 310 may be located between the main hot wire heater 120 and the metal case 110. In this case, the temperature sensing unit 300 may pass through the main insulation layer 122 of the main heating wire heater 120. To this end, the main heating wire heater 120 may include a sensor through hole 120h. The sensor through hole 120h may be located between the patterns of the main heating wire 121.

The temperature sensor 310 may be attached to an upper surface of the main hot wire heater 120. To this end, the temperature sensing unit 300 may further include a second molding member 322 covering the temperature sensor 310 and the first molding member 321.

The temperature sensor 310 may be wrapped by a pair of sensor metal foils 300a. The pair of sensor metal foils 300a may be aluminum or copper clad with relatively high heat transfer efficiency.

The temperature sensor 310 may be located between the main heating wire 121 of the main heating wire heater 120. That is, the temperature sensor 310 may be located between the patterns of the main heating wire 121. Accordingly, the temperature sensor 310 may detect the surface temperature of the metal case 310 more precisely.

Here, the two main heating wires 121a and 121b positioned adjacent to the temperature sensor 310 may have a modified pattern so as not to overlap with the temperature sensor 310. For example, the two main heating wires 121a and 121b having the second width W1 from another adjacent main heating wire 121 may be formed in the second width in the region 121h in which the temperature sensor 310 is located. It may have a pattern having a third width (W) relatively small compared to (W1). Accordingly, the two main heating wires 121a and 121b may have a pattern that avoids the region 121h in which the temperature sensor 310 is located.

The first molding member 321 may surround the temperature sensor 310. Accordingly, the first molding member 321 may prevent the pair of lead wires 311 from being separated from the temperature sensor 310. That is, the first molding member 321 may maintain an electrical connection between the temperature sensor 310 and the pair of lead wires 311.

The tube 340 may prevent the pair of lead wires 311 from being damaged by an external environment. The tube 340 may cover a portion of each lead wire 311. The partial region may be located at an end portion of each lead wire 311. For example, when the temperature sensing unit 300 passes through the main heating wire heater 120, the tube 340 is the second main insulation of the sheathed wire 330 and the main heating wire heater 120. An end portion of each of the lead wires 311 positioned between the layers 122B may be wrapped. Accordingly, each lead wire 311 adjacent to the temperature sensor 310 may have flexibility. Therefore, the temperature sensor 310 may be attached at an appropriate position according to the pattern of the main heating wire 121.

The shrink tube 350 may prevent the electrical connection between the pair of lead wires 311 and the sheathed wire 330 to be blocked by an external environment. That is, the contraction tube 350 may surround the coupling region between the pair of lead wires 311 and the sheathed wire 330. For example, when the pair of lead wires 311 and the sheathed wire 330 are electrically connected by welding, the shrink tube 350 may be connected to the pair of lead wires 311. The welding point G between the sheathed wires 330 may be wrapped.
