A button 22 and a dry button 23 for blowing warm air are provided.
[0032]
Further, a toilet seat button 30 for adjusting the temperature of the toilet seat and a hot water button 31 for adjusting the water temperature of a shower or the like are arranged. Further, although not shown, a wide cleaning on / off button, a cleaning position advance button, and a backward button for adjusting the spread of cleaning are provided. In addition, a strength button for adjusting the strength of washing, a strength button for washing composed of weak buttons, and a human body detection sensor S for detecting the presence or absence of a human body are disposed on the upper surface of the side of the main body 10. Further, although not shown, the human body local washing apparatus is provided with a switch button that enables selection of energization of the hot water heater or toilet seat heater described later.
[0033]
An automatic opening / closing device 200 serving as a driving device is disposed on the shaft 201 that is coaxial with the toilet lid 82 and the toilet seat 81 and is connected to at least the toilet lid 82 around the rotating portion of the toilet lid 82 and the toilet seat 81. Has been. The automatic opening / closing device 200 is a device that detects the presence or absence of a person and opens or closes the toilet lid 82.
[0034]
As shown in FIG. 2, a resistor 204 is disposed on the shaft 201 of the automatic opening / closing device 200. A position detection sensor 202 is disposed at a position facing this resistor 204. As the shaft 201 rotates, the resistor 204 and the position detection sensor 202 are separated from each other or face each other.
[0035]
2 is a diagram conceptually showing the automatic opening / closing device 200 of FIG. 1. Specifically, the position detection sensor 202 and the resistor 204 are viewed from the axial direction of the shaft 201 as shown in FIG. As shown in the figure, the brush B fixed to the gear G slides on the resistor 204 of the potentiometer substrate 202 corresponding to the position detection sensor, so that the signal to the microcomputer is 0V from the closed position to 5V at the open position. Changes linearly. Using this signal, the automatic opening / closing operation of the toilet lid is controlled by a microcomputer.
[0036]
That is, the shaft 201 serving as the output shaft detects the presence or absence of a human body and automatically opens the toilet lid. At this time, since the shaft 201 rotates, the position detection sensor 202 and the resistor 204 are separated from each other, so that the signal to the microcomputer changes from 0V to 5V.
[0037]
FIG. 4 is a block diagram of the position detection sensor 202 for detecting opening / closing of the toilet lid, the microcomputer M, the toilet seat heating heater H1, and the hot water heating heater H2. The microcomputer M is disposed in the control board of the human body local cleaning device. From this block diagram, the toilet lid position detection sensor 202 detects the open / closed state of the toilet lid 83, the signal from the toilet lid position detection sensor 202 is taken into the microcomputer, and the toilet lid heater is detected by the ON / OFF signal output from the microcomputer. H1 and hot water heater H2 are turned ON / OFF.
[0038]
FIG. 5 is an exploded perspective view of the automatic opening / closing device 200 in which a motor, a gear, and the like serving as a driving device are accommodated before being engaged with the upper case 10A. The upper case 10A has a stepped front surface, and a rectangular enclosure 101 is integrally formed with the upper case 10A inside the stepped portion 10AD of the upper case 10A. A plurality of engagement holes 102 and 103 are provided through the surface of the surrounding portion 101.
[0039]
On the other hand, the automatic opening / closing device 200 is provided with engaging projections 202 and 203 that can engage with the engaging holes 102 and 103. As shown in FIG. 7, the engaging protrusion 202 is composed of a claw portion 202A and a substantially L-shaped elastic member 202B. (FIG. 7 is a cross-sectional view taken along the line AA in FIG. 6. FIG. 6 is a cross-sectional view seen from the direction P in FIG. 5.) The elastic member 202A is movable in the left-right direction in FIG. For this reason, the claw portion 202A and the engagement hole 102 can be engaged with each other by an elastic action. Note that the same action can be performed between the engagement protrusion 203 and the engagement hole 103 in FIG.
[0040]
Further, a buffer member 300 made of a polyurethane resin material, a foamed urethane resin material or the like is interposed between the automatic opening / closing device 200 and the surrounding portion 101. The buffer member 300 is fixed to the surface of the automatic opening / closing device 200 in advance. When the automatic opening / closing device 200 having such a structure is assembled in the direction P in FIGS. 5 and 7, the claw portions 202A, 203A of the engagement protrusions 202, 203 of the automatic opening / closing device 200 can be touched into the engagement holes 102, 103 with one touch. Can be inserted and engaged.
[0041]
The toilet seat 81 is fixed to the large-diameter shaft 201A of the shaft 201 of the assembled automatic opening / closing apparatus 200, and the toilet lid 82 is fixed to the small-diameter shaft 201.
[0042]
With the above structure, it has a soundproof effect that prevents the rotation sound of the motor and gear housed in the automatic switchgear from coming out of the device body, and a vibrationproof effect that does not transmit the vibration of the motor and gear to the body case The impact load generated when sitting on the user's toilet seat can be absorbed, and the automatic opening / closing device can be assembled to the case with one touch.
[0043]
Further, by providing a slight gap (about 2 mm) between the claw portions 202A and 203A of the engagement protrusions 202 and 203 and the engagement holes 102 and 103, the user can sit on the toilet seat 81 (the shaft 201). The load can be absorbed in this gap, and the relaxation action is further increased, and there is no possibility of damage to the engagement protrusions 202 and 203 and the automatic opening / closing device 200.
[0044]
Further, by disposing the automatic opening / closing device 200 on the upper case 10A, the switch board SWB and the like (control means) such as LEDs, switches, and automatic opening / closing control circuits assembled in the upper case (FIG. 5). ) Can be shortened, and the wiring between the switch board SWB and the main body control board disposed on the lower case 10B can be minimized. In addition, the tape for fixing the wiring can be reduced.
[0045]
Further, since the wiring of the automatic opening / closing device 200 does not intersect between the upper case 10A and the lower case 10B, it is possible to prevent the wiring of the upper case 10A and the lower case 10B from being caught. Inexpensive 【0046】
【The invention's effect】
The present invention has the following effects.
[0047]
That is, the main body case, a shaft for pivotally supporting the toilet seat or the toilet lid, and an automatic opening / closing device that houses a drive means for driving the toilet seat or the toilet lid so as to be opened and closed. Either one of the opening / closing devices is provided with an engaging protrusion, the other is provided with an engaging hole for engaging with the engaging protrusion, and a buffer means is provided between the main body case and the automatic opening / closing device. Since the toilet device is characterized by being arranged, it has a soundproof effect that prevents the rotation sound of the motor and gear housed in the automatic opening and closing device from coming out of the device body, and the vibration of the motor and gear is suppressed. It has an anti-vibration effect that is not transmitted to the main body case, can absorb the impact load generated when sitting on the toilet seat of the user, and can be assembled to the case with a single touch.
