Abstract
A heater includes: a power source for supplying power; a heating section for receiving power from the power source and converting the received power into heat energy; an electrical leakage breaker circuit for cutting off a power transfer from the power source to the heating section; and a control section for receiving leaked current information from the electrical leakage breaker circuit and operating the electrical leakage breaker circuit when the leaked current amount exceeds a preset amount or electrical leakage breaker state information is stored, wherein when the power transfer is cut off, the control section stores the electrical leakage breaker state information.
Claims13
A heater comprising:
- a power source for supplying power;
- a heating section for receiving power from the power source and converting the received power into heat energy;
- an electrical leakage breaker circuit for cutting off power transfer from the power source to the heating section;
- and
- a control section for receiving leaked current information from the electrical leakage breaker circuit and operating the electrical leakage breaker circuit when the leaked current amount exceeds a preset amount, or operating the electrical leakage breaker circuit when electrical leakage breaker state information is stored,
- wherein when the power transfer is cut off, the control section stores the electrical leakage breaker state information.
A method for breaking current leakage in a heater including an electrical leakage breaker circuit, comprising:
- confirming whether the heater is operating or not, referring to the electrical leakage breaker state information in the heater;
- heating to produce heat energy using the heater when the heater is operating;
- determining whether current or voltage which is supplied to the heater during the heating is within preset range or not;
- operating the electrical leakage breaker circuit and cutting off the power source when the heater is not in an operating state, or the current or voltage supplied to the heater is out of a preset range;
- and
- storing heater electrical leakage breaker state information when the power source of the heater is cut off.
A bidet comprising:
- a power source for supplying power;
- a heating section for receiving power from the power source and heating washing water;
- an electrical leakage breaker circuit for cutting off a power transfer from the power source to the heating section;
- and
- a control section for receiving information of leaked current from the electrical leakage breaker circuit and operating the electrical leakage breaker circuit when the leaked current amount exceeds a preset amount, or operating the electrical leakage breaker circuit when electrical leakage breaker state information is stored,
- wherein when the power transfer is cut off, the control section stores the electrical leakage breaker state information.
A bidet comprising:
- a power source for supplying power;
- a toilet seat having a heater which is heated through power received from the power source;
- an electrical leakage breaker circuit for cutting off a power transfer from the power source to the heater;
- and
- a control section for receiving leaked current information from the electrical leakage breaker circuit and operating the electrical leakage breaker circuit when the leaked current amount exceeds a preset amount, or operating the electrical leakage breaker circuit when electrical leakage breaker state information is stored,
- wherein when the power transfer is cut off, the control section stores the electrical leakage breaker state information.
