DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device for heating a toilet seat.

[0002]

2. Description of the Related Art Conventionally, a heater built in a toilet seat is energized to heat the toilet seat. However, since the heater is continuously energized, there is much waste due to heat dissipation from the toilet seat, and electric power is not consumed. However, there was a problem that was wasted.

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and is directed to a toilet seat heating device capable of effectively heating the toilet seat only when the toilet seat is used to obtain a power saving effect. The first gist of the present invention is to provide a capacitor that stores in advance a current to be supplied to a heater built in a toilet seat, a human body sensor that detects in advance the use of the toilet seat, and a sensor from the human body sensor. A switch means for supplying a discharge current of the capacitor to the heater before the user sits on the toilet seat according to the sensing signal. A second gist is that the heater is not energized when the toilet seat is opened within a predetermined time after the human body sensor detects a human body. A third aspect is that a voltage drop unit that drops a voltage is provided, and the capacitor is charged with the voltage dropped by the voltage drop unit when the toilet is not used.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a toilet bowl, in which a toilet seat 3 is provided on a toilet body 2 of the toilet bowl 1 so as to be openable and closable, and a low tank 4 is provided upright at a rear portion of the toilet body 2. On the front side of the low tank 4, there is provided a human body detection sensor 5 which senses the human body of the user when the user stands in front of the toilet body 2 and emits a detection signal. A seating sensor 6 that emits a seating signal when a user sits on the toilet seat 3 is provided on the lower surface side of the toilet seat 3 and the like. Toilet seat open signal generator 3a
However, the toilet seat 3 is provided, for example, in the vicinity of a rotation axis of the toilet seat 3, and a heater 7 for heating the toilet seat 3 is built in the toilet seat 3.

In this example, the circuit configuration is as shown in the block diagram of FIG. 2. A voltage drop means 9 is connected to a power supply 8 of a general commercial power supply of 100 volts or 200 volts. 9 for example 100 volts to 2
A rectifier 10 for rectifying to DC is provided downstream of the voltage drop means 9, and a resistor 1 is provided downstream of the rectifier 10.
1 is provided, and a capacitor 12 is further connected in parallel, so that the rectified current is stored in the capacitor 12.

The resistor 11 is provided so that a breaker does not fly when the capacitor 12 is charged. By providing the resistor 11, the wiring can be formed by a relatively thin wiring. Further, a switch means 13 is provided downstream of the condenser 12,
The switch unit 13 includes a switch unit 13 a having a contact for opening and closing the heater 7 built in the toilet seat 3.
And a control unit 13b for opening and closing the switch unit 13a.
The control unit 13b is configured to receive a signal from the human body sensor 5 and the control unit 13b receives a signal from the seating sensor 6 and the toilet seat opening signal generator 3a. Is input. The capacitor 12 is formed of a small-sized and large-capacity electric double-layer capacitor. The human body sensor 5 is constituted by an infrared sensor or an ultrasonic sensor, and the seat sensor 6 is constituted by, for example, a capacitance type sensor.

In such a configuration, the current which is transformed to a low voltage of, for example, about 24 volts by the voltage drop means 9 and rectified by the rectifier 10 is stored in the capacitor 12, and in this state, the toilet 1 When the user stands before the user, the human body sensor 5 detects the human body and the control unit 13b
And the control unit 13b recognizes that the toilet is in a use state and closes the switch unit 13a. As a result, the electric charge stored in the capacitor 12 is rapidly and rapidly discharged to the heater 7 in a short time.
Can be heated in a short time, and the toilet seat 3 is instantaneously warmed before the user sits on the toilet seat 3, so that the user can obtain a good feeling of use without feeling cold in the buttocks. .

That is, in this embodiment, the use of the toilet seat 3 is detected in advance by the human body detecting sensor 5, and a large current from the condenser 12 is supplied to the heater 7 before the user sits on the toilet seat 3. It is possible to create a state in which the toilet seat 3 is properly warmed when sitting on the toilet seat 3. In addition,
When the user sits on the toilet seat 3, the seating sensor 6 senses the seating state and sends a signal to the control unit 13b. At this time, the switch unit 13a is opened via the control unit 13b, and thereafter the heater 7 is turned on. Can be configured so as not to be energized, and the heater 7 rapidly raises the temperature by the large current from the capacitor 12 and is thereafter cut off, so that the toilet seat 3 is maintained in a good heat retaining state by preheating. Is done. In addition, since the energization is cut off, the power saving effect can be improved.

When a seating signal is input from the seating sensor 6, the control unit 13b may perform control to maintain the switch unit 13a in the closed state. After the large current is passed, a weak current is continuously passed, and the heater 7 is continuously heated. It should be noted that, after the user leaves, the control unit 13b opens the switch unit 13a by a signal from the seating sensor 6,
The energization of the heater 7 is stopped, and a power saving state is set. In addition,
In this example, since the voltage drop means 9 reduces the current of, for example, 100 volts to a current of about 24 volts, the toilet seat 3 is provided in a toilet installed in, for example, a unit bath where water tends to splash. In some cases, safety is improved.

[0010] For example, when a man performs urination, even if the human body sensor 5 detects a man, the man immediately opens the toilet seat 3 for urine. At this time, the toilet seat open signal generator 3a Sends a signal to the control unit 13b. In this case, the control unit 13b can keep the switch unit 13a in the open state and control so that the heater 7 is not energized. Can be configured so that the heater 7 is not energized unnecessarily.

[0011]

According to the toilet seat heating apparatus of the present invention, a capacitor for preliminarily storing a current to be supplied to a heater built in the toilet seat, a human body sensor for previously detecting use of the toilet seat, and a sensing from the human body sensor. Before the user sits on the toilet seat, by providing a switch means for passing the discharge current of the capacitor to the heater before the user sits on the toilet seat, the use of the toilet seat is detected in advance by the human body sensor, and before the user sits on the toilet seat, The electric charge stored in the condenser is rapidly discharged to the heater in a short period of time, and the heater is rapidly heated, so that when the user sits down, the toilet seat can be heated well, giving a good feeling of use. And the heater is not normally energized, so that the power saving effect can be improved.

Further, when the toilet seat is opened within a predetermined time after the human body sensor detects the human body, the heater is not energized, so that when the male uses the toilet for urination. In this case, the toilet seat is opened and used without sitting on the toilet seat, and in this case, the heater is not wastefully energized, and the power saving effect can be improved.

[0013] Further, a voltage drop means for dropping a voltage is provided, and the capacitor is charged with the voltage dropped by the voltage drop means when the toilet is not used, so that the capacitor is used as a low voltage by the voltage drop means. Therefore, for example, there is an effect that the safety can be enhanced and used even in a toilet seat installed in a unit bath where water is likely to be applied.
