Abstract

PURPOSE: To improve the quick heating property of a heated toilet seat and to improve an energy saving effect by making the temperature distribution of a toilet seat surface uniform, by composing this device of an excited coil for heating for generating a magnetic field with a current sent from a power source for induction heating and a heating element to generate heat with a guide current to be induced. CONSTITUTION: An induction heating type heated toilet seat 2 is composed of an excited coil 10 for heating, heating element 11 for guide current generation, and a toilet seat cover 12. When a human being sits down on the toilet seat, a sitting switch 17 is tuned on, a microcomputer 13 detects this sitting and starts an inverter power source 3 and, at the same time, a switching means 4 switches power from the inverter power source 3 to the side of the induction heating type heated toilet seat 2. Concerning the heated toilet seat 2, supplied power flows to the excited coil 10 for heating, a heating plate 11 is heated by the induction heating, and the human body is heated through the toilet seat cover 12. When power is supplied, concerning the induction heating, the guide current is instantaneously generated at the heating element 11 and, since there is a system to generate heat at the heating element 11, the toilet seat is heated just after sitting so that the uncomfortable feeling of coldness is not applied to the human body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet flush toilet seat device for flushing anus using warm water.

[0002]

2. Description of the Related Art Conventionally, in this type of technique, a heater 18 for a hot water unit for heating water as shown in FIG. 3 and a heater 19 for a heating toilet seat are composed of independent heating elements and have independent electric power. Heating control is performed in the supply path. Further, the heating toilet seat has a structure in which a tubing heater in which a metal heating element is coated with resin is pressed against the back surface of the resin toilet seat.

[0003]

However, in the above-mentioned structure, the heat transfer from the heating element is poor in the heating toilet seat, too.
There was a problem that the surface of the toilet seat could not be heated instantaneously.

The present invention solves such a problem. A hot water type toilet seat with a high energy saving effect is obtained by improving the immediate heating property of the heated toilet seat, inserting a heating toilet seat heater in the early stage of seating, and turning off the heater other than that. The purpose is to provide.

[0005]

In order to solve the above problems, an induction heating type heating toilet seat according to the present invention is a heating excitation coil for generating a magnetic field by an induction heating power source and a current sent from the induction heating power source. And a heating element that generates heat by an induction current induced by the heating exciting coil as a base body.

With the above arrangement, an induction current is generated in the heating element by the AC magnetic field induced by the AC power supplied from the induction heating power source to the heating excitation coil. This induced current instantly heats the heating element, and the toilet seat surface is instantly warmed.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to an induction heating power source for generating AC power, a heating excitation coil for generating a magnetic field by a current sent from the induction heating power source, and induction by the heating excitation coil. And a heating element that generates heat by an induced current.

When an alternating current is supplied from the induction heating power source to the heating excitation coil, the lines of magnetic force generated by the excitation coil penetrate through the heating element. When the direction of the lines of magnetic force changes according to the cycle of the supplied alternating current, an electric force that acts to prevent the change of the lines of magnetic force acts on the heating element, and a current in the direction opposite to the coil current flows in the heating element. Induced. This induced current causes the heating element to generate heat, which instantly warms the toilet seat surface.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, 1 is an induction heating hot water unit, 2 is an induction heating heating toilet seat, 3 is an induction heating inverter power source, 4 is power from the induction heating inverter power source 3, and the heating water unit 1 side and the heating toilet seat. Switching means for switching to the 2 side, 5 is a pump for pumping cleaning water, 6 is a scrubbing nozzle for spraying cleaning water, and 7 is a switching valve for nozzles. The induction heating hot water unit 1 is composed of a heating coil 8 and a heating pipe 9. The induction heating type heating toilet seat 2 is composed of a heating excitation coil 10, an induction current generating heating element 11, and a toilet seat cover 12. The heating exciting coil 10 which is a charging part, the heating element 11 for generating an induced current, and the heating toilet seat portion including the toilet seat cover 12 can be detached due to magnetic coupling.

Reference numeral 13 denotes a microcomputer, which has an operating unit 14, a hot water temperature sensor 15 attached to the outlet of the hot water unit 1, a temperature sensor 16 attached to the induction heating type heating toilet seat 2, and an inverter power supply 3 in response to input signals from a seating switch 17. The switching means 4 is controlled.

In the above structure, when a person sits down on the toilet seat due to a toilet, the seating switch 17 is turned on, and the microcomputer 13 detects the seating switch 17 to start the inverter power supply 3 and at the same time.
The switching means 4 switches the electric power from the inverter power supply 3 to the induction heating type heating toilet seat 2 side. The electric power supplied to the heating toilet seat 2 flows to the heating exciting coil 10 to heat the heating plate 11 by induction heating. As a result, the human body is heated via the toilet seat cover 12. Since this induction heating is a method in which an induction current is generated in the heating element 11 as soon as power is supplied, and the heating element 11 generates heat, the toilet seat is heated immediately after seating and is said to be cold to the human body. No discomfort.

Next, when the toilet is finished and the washing switch is turned on at the operation unit 14, the microcomputer 13 detects this and the pump motor 5 and the inverter power source 3 are started, and at the same time, the switching means 4 is switched from the inverter power source 3 to the switching means 4. The electric power of is switched to the hot water unit 1 side. The cleaning water sent from the pressure pump 5 is
Electric power supplied from the inverter power supply 3 is applied to the heating coil 8
And is heated by an induction current induced in the heating pipe 9 and flowing in the heating pipe 9.

The temperature of the heated washing water is detected by the hot water temperature sensor 1.
5. The temperature is controlled via the microcomputer 13.
The washing water whose heating is controlled is sprayed through the switching valve 7 to the washing nozzle 6 according to the purpose of use for anal washing or bidet washing to wash the local area.

[0014]

As described above, according to the hot water type flush toilet seat device of the present invention, the following effects can be obtained.

(1) Heating Toilet seat heating can be instantaneously heated, power supply can be stopped except when seated, without keeping the toilet seat in a heat-retaining state, and a great energy saving effect can be exerted. it can.

(2) By forming the heating element in a planar shape, the temperature distribution on the surface of the toilet seat is made uniform, and the comfort during seat heating is improved.

(3) Because of the induction heating structure, the charging part through which the current flows, the washing water, and the human body are not in direct contact with each other.
Therefore, safety against electric shock is enhanced. Further, the heating element toilet seat portion can be configured to be detachable from the heating excitation coil portion that is the charging portion, and the toilet seat surface can be easily cleaned and cleaned.
