[0024]
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. 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.
[0025]
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.
[0026]
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.
[0027]
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.
[0028]
Then, the flowchart regarding this invention is shown in. From the previous step A (P1), if the opening angle of the toilet seat or toilet lid is 10 ° or less in the determination at P2, the lock detection time is set to 500 msec (P3). If it is 10 ° or more, it is set (P4) at 50 msec, which is conventionally performed.
[0029]
After being set to 500 msec or 50 msec, it is determined in P5 whether the toilet seat is locked. If the toilet seat is locked, the control is terminated. If it is determined that the toilet seat is not locked, it is determined that there is no abnormality and the process proceeds to the next step B.
[0030]
FIG. 7 is a graph showing the relationship between the toilet seat opening angle (horizontal axis) and the lock detection time (vertical axis). From this graph, the lock detection time is 500 msec when the opening angle of the toilet seat is 10 ° or less, and the lock detection time is 50 msec when the opening angle of the toilet seat is 10 ° or more.
[0031]
A diagram represented by a dotted line represents a conventional lock detection time. Conventionally, the lock detection time is set to a fixed time of 50 msec from fully closed to fully open of the toilet seat.
[0032]
FIG. 6 is an operation diagram in which the toilet seat 81 rotates with respect to the toilet bowl 83 made of earthenware. From this figure, when the opening angle of the toilet seat is 10 ° or less, the lock detection time is set at 500 msec, and when it is 10 ° or more, it is set at 50 msec.
[0033]
In this embodiment, the predetermined angle has been described as 10 °. However, the predetermined angle is not limited to this, and is basically an angle of 30 ° or less, preferably 5 ° to 15 °. That is, if the predetermined angle is in the range of 5 ° to 15 °, setting a long lock detection time to a lower angle has the advantage that the pain of obstacles such as humans can be reduced. If the angle is less than 5 °, the angle when the motor is idle when the rubber is adsorbed is insufficient. In other words, due to idling, the signal from the motor is 5 ° but may not actually open. When it is 15 ° to 30 ° or more, pain may be felt when a hand or the like is taken out at a position with a high closing angle.
[0034]
In the present embodiment, the lock detection time below a predetermined angle near the toilet seat closing is controlled to be longer than the lock detection time above the predetermined angle. It is also possible to perform control to change the setting of the lock detection time to a short time when a predetermined time or more has elapsed since the instruction to open in the direction.
[0035]
That is, as shown in the flowchart of FIG. 8, the lock detection time is set to 500 msec (F2) from the previous step F1. Thereafter, in F3, it is determined whether or not the elapsed time from the instruction in the opening direction has passed 2 seconds. If the elapsed time is 2 seconds or more, the lock detection time can be reset to 50 msec. In addition, although this time was set to 2 seconds, it cannot be overemphasized that it can set arbitrarily.
[0036]
Further, in the present invention, the opening / closing angle of the toilet seat has been described as an example, but it can also be used for opening / closing the toilet lid instead of the toilet seat.
[0037]
【The invention's effect】
The present invention has the following effects.
[0038]
That is, when there is an instruction to open the toilet seat etc. in the toilet body, a drive device that pivotally supports the toilet seat etc. on the toilet body, and that drives the toilet seat etc. to open and close A control device comprising lock detecting means for detecting a stop time of the toilet seat or the like, wherein the lock detection time at a predetermined angle or less near the closing of the toilet seat or the like is set longer than the lock detection time at or above the predetermined angle Because it is a toilet device characterized by having a toilet seat, etc., the lock on the toilet seat, etc., placed on the back side of the toilet seat, etc., and the toilet seat, etc. are reliably detected due to adhesion, etc. It has the effect that it can do.
