## Abstract

A temperature-controllable heated seat includes: a housing providing a certain amount of internal space; heating wires disposed within the housing, having bent portions repeated from one end portion to the other end portion of the housing, and heating the housing upon receiving power; and a thermostat unit disposed at a periphery of the heating wires and controlling power supply to the heating wires such that the temperature of the housing does not exceed a pre-set temperature value.

## Claims

### Claim 1

A temperature-controllable heated seat comprising:
a housing providing a certain amount of internal space;
heating wires disposed within the housing, having bent portions repeated from one end portion to the other end portion of the housing, and heating the housing upon receiving power; and
a thermostat unit disposed at a periphery of the heating wires and controlling a power supply thereto, such that the temperature of the housing does not exceed a pre-set temperature value.

### Claim 2 (depends on 1)

The temperature-controllable heated seat of claim 1, wherein the thermostat unit is separated from the heating wires by a predetermined distance.

### Claim 3 (depends on 2)

The temperature-controllable heated seat of claim 2, wherein the predetermined distance ranges from 1 mm to 5 mm.

### Claim 4 (depends on 3)

The temperature-controllable heated seat of claim 3, wherein the pre-set temperature value ranges from 43 degrees Celsius to 47 degrees Celsius.

### Claim 5 (depends on 1)

The temperature-controllable heated seat of claim 1, wherein the thermostat unit is disposed above the heating wires.

### Claim 6 (depends on 5)

The temperature-controllable heated seat of claim 5, wherein the pre-set temperature value ranges from 40 degrees Celsius to 44 degrees Celsius.

### Claim 7 (depends on 1)

The temperature-controllable heated seat of claim 1, wherein the degree of precision of the thermostat unit ranges from 0.5 degrees Celsius to 2.5 degrees Celsius.

### Claim 8 (depends on 1)

The temperature-controllable heated seat of claim 1, wherein the thermostat unit comprises a thermostat and wire connection terminals, and the wire connection terminals and wires connected thereto are integrally molded.

### Claim 9

A temperature-controllable heated bidet comprising:
a toilet seat providing a certain amount of internal space;
heating wires disposed within the toilet seat, having bent portions repeated from one end portion to the other end portion of the toilet seat, and heating the toilet seat upon receiving power; and
a thermostat unit disposed at a periphery of the heating wires and controlling power supply to the heating wires such that the temperature of the toilet seat does not exceed a pre-set temperature value.

### Claim 10

A method for controlling a temperature of a heated bidet, the method comprising:
a toilet seat heating operation of heating a toilet seat by supplying power to heating wires;
a power cutoff operation of cutting a power supply by disconnecting the heating wires and a power source by a thermostat when the temperature of the toilet seat reaches a pre-set temperature value; and
a power re-supply operation of resuming power supply by connecting the heating wires and the power source by the thermostat when the temperature of the toilet seat is dropped to be lower than the pre-set temperature value.
