BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seating position detecting device for detecting the position of the buttocks of a human body sitting on the toilet seat of a Western-style toilet, and a hot water washing device using the seating position detecting device.

[0002]

2. Description of the Related Art As is well known, a hot water washing apparatus is designed to wash a buttocks by jetting hot water from a nozzle toward a buttocks of a human body sitting on a toilet seat. It has a mechanism to supply hot water to the water.

As this nozzle, there is a nozzle in which a nozzle body is inserted into a cylinder, the nozzle body is advanced by hot water pressure, and hot water is ejected from the tip of the nozzle body. As another nozzle, there is a swing-type nozzle in which a nozzle arranged below a hip is swung by operating a handle disposed on a side of the Western-style toilet.

[0004]

In any of the above types of nozzles, the position of the tip of the nozzle during the cleaning operation (when hot water is jetted) is constant. Therefore, the user seated on the toilet seat needs to adjust the buttocks position so that the jet of water jetted upward from below hits the location to be washed.

[0005] If hot water is spouted with the buttock position incorrect, the hot water scatters around the toilet.

[0006]

According to a first aspect of the present invention, there is provided a seating position detecting device, wherein a plurality of human body detecting sensors are provided at different positions in the front-rear direction of the toilet seat, and a plurality of human body detecting sensors are provided on the toilet seat based on a signal from the sensor detecting the human body. Is detected.

According to a second aspect of the present invention, there is provided a seating position detecting device located at a position rearward of the toilet seat and higher than the upper surface of the seated toilet seat.
The location, providing a distance sensor for measuring a distance to the seated person,
The buttock position on the toilet seat is detected based on the detection distance of the sensor.

According to a third aspect of the present invention, there is provided a hot water washing apparatus having a nozzle for jetting hot water toward a buttocks of a human body sitting on a toilet seat. A nozzle position adjusting device is provided which adjusts the front-back position of the nozzle according to the hip position detected by the position detecting device.

According to a fourth aspect of the present invention, there is provided a hot water washing apparatus having a nozzle for jetting hot water toward a buttocks of a human body seated on a toilet seat, wherein the seating position detecting device according to the first or second aspect is provided. An alarm device for outputting an alarm when the buttocks position detected by the position detection device is out of a predetermined regular position is provided.

[0010]

In the seating position detecting device according to the first aspect, since a plurality of sensors are provided in the front-rear direction of the toilet seat, the buttocks position is determined from the sensor that detects the human body and the sensor that does not detect the human body. Can be detected.

In the seating position detecting device according to the second aspect,
At the rear of the toilet seat and above the top of the seat
The position in the front-back direction of the human body, that is, the buttocks position can be detected from the distance between the human body and the distance measurement sensor provided at the upper position .

According to the third aspect of the present invention, since the nozzle position is adjusted according to the position of the buttocks, the hot water always hits the required washing position of the buttocks.

According to the fourth aspect of the present invention, an alarm is output if the buttocks position is incorrect, so that the seated person can recognize that the buttocks position is incorrect.

FIG. 7 shows a capacitance sensor 6 for detecting the buttocks.
FIG. 8 is a plan view of the toilet seat 62 provided with
FIG. 9 is a circuit block diagram of a seating position detecting device using 0, and FIG. 9 is a time chart showing the operation of the circuit.

A plurality of sensors 60 are provided on the back surface of the toilet seat 62 in the front-rear direction. A pair of electrodes of each sensor is input to the monostable oscillator of the seating position detecting device shown in FIG. This monostable oscillator has a frequency from a reference oscillator (for example, 50 kHz to 100 kHz).
KHz) output, and the monostable oscillator Q output and the monostable oscillator Q output are input to the NOR circuit. The output of the NOR circuit is output through a detection circuit, an amplifier, and a switching circuit. Constant voltage _Vcc
Are connected to the respective electrodes of the sensor 60 via the resistors R ₁ and R ₂ . Further, a voltage obtained by dividing the constant voltage _Vcc by the variable resistor 64 is input to the monostable oscillator.

The operation of the capacitance comparison type seating position detecting device is as follows.

The output of the reference oscillator is input to two monostable oscillators as reference inputs and triggers them. In the monostable oscillator, the pulse width of the Q output changes according to the time constant of the resistance R ₁ and the capacitance C ₁ of the sensor 60. The monostable oscillator includes a resistor R ₂ and a capacitance C _{2 of the} sensor 60.
Changes the pulse width of the Q output. The output ( Q , Q) of the monostable oscillator is input to the NOR circuit. When the pulse width of each Q output of the monostable oscillator is the same, the output of the NOR circuit becomes 0. The change in the pulse width is proportional to the change in the capacitances C ₁ and C ₂ . By changing R ₁ and R ₂ so that the pulse width of the Q output of each monostable oscillator becomes the same and keeping the equilibrium state, the influence of the capacitance around C ₁ and C ₂ can be ignored. Adjust it to In this case, the output (Q, Q ) of the monostable oscillator is (0, 1), as shown in FIG.
Or (1, 0), and the output of the NOR circuit becomes 0.
Even when the human body is seated on the toilet seat and slight changes in C ₁ and C ₂ occur, there occurs a time zone in which the outputs (Q, Q ) of the monostable oscillator are both (0, 0). Becomes 1. Therefore, when the buttocks of the human body are present on the sensor 60, the NOR circuit outputs a rectangular wave AC signal. This AC output is rectified by a detection circuit to form a pulsating flow near DC, and further transmitted to a switching circuit through a DC amplifier. It is output to the outside as a digital human body detection signal by a switching circuit. The buttocks position is determined from the arrangement of the sensor 60 that detects the human body and the sensor 60 that does not detect the human body.

The seating position detecting device shown in FIGS. 7 and 8 has the following advantages. (1) The output changes depending on the balance between C ₁ and C ₂ , so that the sensitivity is high; (2) The margin for noise can be widened; Good temperature characteristics;
