[Prior art]
Conventionally, a toilet device is provided with a cleaning function, a heater, a deodorizing mechanism, and the like, and these are controlled using a seating sensor or the like. This seating sensor detects seating when light is blocked from the light emitting unit and the light receiving unit, and can operate a cleaning mechanism or the like depending on the detection position. In addition, in the speed governing device used to ease toilet lid falling rotation used for toilet lids, etc., it is not involved in the control of the seating sensor (human body detection sensor), and the seating sensor is always activated (switch-on). ) State, it operates even when the toilet lid is in a closed state, causing a malfunction of the cleaning mechanism. Japanese Laid-Open Patent Publication No. 6-123187 discloses a speed governor for a rotating body that solves this problem. In order to prevent malfunctions by switching the operating state of a seating sensor that detects an object according to the position of a rotating body such as a toilet lid, braking is applied in one direction of the rotating body that is supported so as to be freely opened and closed. The speed control device for the rotating body to be applied has a switch means for operating the detecting means for detecting the presence of the object in the open state of the rotating body and stopping the detecting means in the closed state of the rotating body in conjunction with opening and closing of the rotating body. A construction technique is disclosed.

Each of the above means can be operated by the main body switch panel 2. The main body 10 has warm water cleaning means 6 and warm air drying means (not shown) including cleaning nozzles 61 and 62 and the like. The main body 10 includes a toilet seat 81 and a toilet lid 82 and is disposed above a ceramic toilet bowl 83.
[0014]
The main body switch panel 2 is arranged on the upper surface of the side portion of the main body 10.
[0015]
The main body switch panel 2 includes a stop button 20 for stopping operations such as anal washing, bidet washing, and hot air drying, an anal washing operation button 21, a soft anal washing operation button 29 capable of soft washing, and a bidet washing operation. A button 22 and a dry button 23 for blowing warm air are provided.
[0016]
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. Although not shown, the toilet device is provided with a switch button that enables selection of energization of the hot water heater or toilet seat heater described later. Therefore, switching from the normal mode to the power saving mode (or vice versa) can be selected.
[0017]
As shown in FIG. 1, the toilet lid rotating shaft 201 and the toilet seat rotating shaft 205 are coaxial on the periphery of the rotating portion of the toilet lid 82 and the toilet seat 81. The toilet lid rotating shaft 201 coupled to the toilet lid 82 and the toilet seat rotating shaft 205 coupled to the toilet seat 81 are provided with a speed control device 300 that applies braking in the closing direction of the toilet lid 82 and the toilet seat 81, respectively. Yes.
[0018]
2A is a partial cross-sectional view of the speed governor 300, FIG. 3 is a view as viewed from the direction A in FIG. 2A (the substrate 400 is omitted), and FIG. 2B is a view of FIG. It is a BB sectional view.
[0019]
As shown in FIG. 2A, the speed control case of the speed control device 300 is composed of a speed control device case 304 composed of three members 301, 302, and 303 in assembling. In the speed control case 304, a toilet lid rotating body 201 coupled to the toilet lid 82 and a toilet seat rotating body 205 coupled to the toilet seat 81 are partially stored. Further, speed control means 305 and 306 for braking in one direction of the toilet lid rotation shaft 201 are formed. The speed control means 305 and 306 have oil space portions 305 and 306 formed therein. Oil such as silicon oil having viscosity is sealed in the oil spaces 305 and 306.
[0020]
As shown in FIGS. 2B, 3, and 5 (enlarged detailed explanatory diagram of FIG. 3), the toilet lid rotating shaft 201 has two protruding portions 201 a protruding in the radial direction. In the rotation direction of the protrusion 201 a, the valve body 201 c is loosely fitted in a through hole 201 b that extends through the protrusion 201 a so that the valve body 201 c can freely move in the rotation direction of the toilet lid rotation shaft 201.
[0021]
Here, as shown in FIG. 4, the valve body 201c opens between the valve body 201c and the through hole 201b when the toilet lid rotating shaft 201 is rotated in the A direction (toilet lid opening direction), and the oil is in the gap. The braking force does not work by flowing through. Further, when the toilet lid rotation shaft 201 is rotated in the A direction, the valve body claw portion 201d and the through hole are brought into contact with each other, and the valve body 201c is stopped.
[0022]
On the other hand, when the valve body 201c is rotated in the B direction (toilet lid closing direction), the through hole 201b is sealed by the valve body 201c, and when the valve body 201c is further rotated in the B direction, a braking force in the B direction works due to the resistance of oil.
[0023]
The toilet seat rotating shaft 205 also has a structure in which a braking force acts in the toilet seat rotating closing direction by a valve body and a through-hole disposed in the speed adjusting means 306, similarly to the toilet lid rotating shaft 201.
[0024]
FIG. 5 is an explanatory diagram showing the relationship between the detection sensor 401 and the detected object 500. On the toilet lid rotating shaft 201, a detection object 500 made of a magnet is disposed in the vicinity of the detection sensor 401. A substrate 400 is fixed to the other end 301 of the toilet lid rotating shaft 201 on the governor case 305 side by a substrate fixing screw SK. A detection sensor 401 comprising a Hall IC or a reed switch is disposed on this board, and a signal indicating the opening / closing state of the toilet lid 82 is sent to the microcomputer control device of the toilet device via a lead wire (not shown). Note that the other end 301 of the governor case 305 has a case body 301, 302, 303 fixed to the case body with a screw SH.
[0025]
The lead wire has a plurality of lead wire solder holes 401 formed on the substrate 400. The substrate is fixed by four substrate fixing screws SK.
[0026]
In FIG. 5, the position A by the rotation of the toilet lid rotating shaft 201 is the position of the detected object 500 where the opening angle θ = 0 ° of the toilet lid 82 and the position B is the opening angle θ = 65 ° of the toilet lid 82. It is.
[0027]
With this structure, the detection sensor 401 detects the opening / closing of the toilet lid 83 from the proximity state of the detection object 500 at the A position to the separation state of the B position.
[0028]
【The invention's effect】
The present invention has the following effects.
[0029]
That is, the speed governor case includes a rotating shaft coupled to the rotating body, speed adjusting means for braking in one direction of the rotating shaft, and a detection object disposed on the rotating shaft, Since the speed control device case is provided with a detection sensor disposed in the vicinity of the detected object, and the detection sensor detects at least two different positions of the rotating shaft. Since the shield member is not required and the space for the shield member is not required, it is compact, the number of parts can be reduced, and the cost is advantageous.
