Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a local part of a human body using a strain amount detecting device.

2. Description of the Related Art As shown in JP-A-60-184136 and FIG. 3, a human body local cleaning device 1 comprises a toilet bowl 3 fixed to a floor 2 and a box-shaped cleaning water tank (cistern) 4 behind the toilet bowl 3. , A washing device main body 5 in front of the tank 4, and a toilet seat 6 on the toilet bowl 3. The toilet 3 is provided with a nozzle for discharging cleaning water at an appropriate temperature and a drying air discharge port for sending drying air at an appropriate temperature to a cleaned human body. Further, the tank 4 is provided in the cleaning device main body 5.
A heater for adjusting the temperature of the washing water from the water to an appropriate temperature, a dryer for adjusting the temperature of the air to the human body, a pump for pumping the washing water to a nozzle for discharging the washing water, and an electric circuit means for controlling the same. The electric circuit means in the cleaning device main body 5 generally has a receiving portion for receiving a signal from the control means 7 provided on the toilet wall, and operates the heater and the dryer in accordance with the received signal.

The control means 7 provided on the toilet wall has a flush water discharge switch, a dry air discharge switch, a knob or a switch for adjusting the water temperature, the water volume, the blast temperature, and the blast volume, and is further determined by operating these switches and the knob. A signal emission port for sending a signal to be transmitted. The signal from the signal discharge port is received by the receiving unit of the cleaning device main body 5 and sends necessary cleaning water and wind to the human body part.

For example, in an example using an optical signal, an upward optical signal from the remote control unit 7 is reflected on the toilet ceiling or a reflector on the upper part of the remote control unit 7 to change its direction downward. The light is received by the light receiving section on the top wall. Apart from such an optical signal, a wired electric signal may be transmitted to the cleaning device main body 5.

Problems to be Solved by the Present Invention For example, if the user inadvertently presses the hot water switch of the control means before sitting on the toilet seat, the hot water spouts from the nozzle, and stains not only the toilet floor but also the user's clothes. Will be. For this reason, when the user sits on the toilet seat, the human body local cleaning device senses the seating and turns on the electric circuit means of the cleaning device main body. In order to turn on the electric circuit means in this way, as shown in Japanese Utility Model Laid-Open No. 24799/1987, a part of the toilet seat is elastically deformed by the weight at the time of sitting on the toilet seat, and the micro switch is turned on. A configuration for setting the state is adopted. The amount of elastic deformation of a part of the toilet seat is
In order to make the contact longer than the stroke required for turning on the microswitch, when the user sits on the toilet seat, the user feels like the toilet seat sinks, and the feeling during use is deteriorated.

Therefore, an object of the present invention is to solve the above-mentioned disadvantages of the related art.

Means for Solving the Problems In order to solve the above-described problems, the present invention provides an electric switch connected to an operation switch by a distortion amount detecting device that senses the weight of a user when the user sits on a toilet seat. In order to make the circuit energizable, technical means for disposing the distortion amount detecting device between the front and rear legs on the back surface of the toilet seat is basically adopted.

When a person sits on the toilet seat, the toilet seat or its peripheral portion causes a distortion phenomenon due to body weight.In the present invention, this distortion is detected by the distortion amount detection device, and the electric circuit is turned on.
When the distortion disappears (when the person moves away from the toilet seat), the electric circuit is turned off, and even if the operation switch is pressed, the electric circuit is not operated.

Embodiment An example of a human body local cleaning apparatus to which the present invention can be applied is basically the same as the example shown in FIG. 3, so that the same components are denoted by the same reference numerals and description thereof is omitted here. I do.

A footrest 8 in front of and behind a toilet seat 6 which is held openably and closably on the toilet 3
The distortion amount detecting device 9 is attached to the back surface almost at the center in the middle, and the distortion amount detecting device 9 is incorporated in a circuit as shown in FIG.

The resistance value of the distortion amount detection device 9 is small when not seated, and the inverting input to the comparator 11 determined by the resistance value of the distortion amount detection device 9 and the voltage dividing resistor 10 of the reference voltage _VDD is a comparison voltage setting resistor.
When the input is smaller than the non-inverting input to the comparators 11, 12, the output of the comparator 11 becomes a HIGH signal, and the HIGH signal is input to the microcomputer input terminal 14.

On the other hand, when sitting, the resistance value of the distortion amount detecting device 9 is large, and the inverting input of the comparator 11 determined by the resistance value of the distortion amount detecting device 5 and the voltage dividing resistor 10 of the reference voltage _VDD becomes the comparative voltage setting resistor 12. , 13, the output of the comparator 11 becomes a LOW signal, and the microcomputer input terminal 14 receives the LOW signal.

That is, the microcomputer 15 determines that the HIGH signal of the microcomputer input terminal 14 is not seated and turns off the electric circuit means. The microcomputer 15 determines that the LOW signal of the microcomputer input terminal 14 is seated, and turns on the electric circuit means. In addition, 16
Denotes a noise removing capacitor, and 17 denotes a pull-up resistor.

In the above-described embodiment, when the user sits on the toilet seat, the toilet seat is distorted. Separately, distortion is given to the toilet seat in advance, and the distortion is eliminated by sitting on the toilet seat. May be detected to make the power supply possible.

Instead of attaching the distortion amount detecting device 9 to the toilet seat 6, the distortion amount detecting device 9 may be attached to a proper position of the cleaning device main body 5 that causes distortion similarly to the toilet seat 6. Apart from the example of FIG. 2, a resistor may be provided between the input and output of the comparator 11 to provide hysteresis between the non-seated, seated and non-seated operations. Separately from this, without using the comparator 11, the microcomputer input terminal 14 may be an analog input terminal, and depending on the magnitude of the voltage of the analog input terminal 14, the non-seated or seated state may be determined by the microcomputer 15,
Further, the above-mentioned hysteresis signal may be input to the microcomputer 15 to determine non-seating and sitting.

Effect The use of the strain amount detection device is highly reliable with no contact deterioration due to sparks due to the opening and closing of the contacts.
