  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a perspective view of a toilet facility according to an embodiment, FIG. 2 is a control block diagram thereof, and FIG. 3 is a control flowchart thereof.

  A toilet seat box 2 is installed on the upper surface of the rear part of the toilet body 1 having the toilet bowl 1a. The toilet seat box 2 is provided with an overhanging portion 2 a that protrudes to the side of the toilet body 1. A toilet seat 3 and a toilet lid 4 are attached to the toilet seat box 2 so as to be able to turn upside down. In the toilet seat box 2, an opening / closing drive device 5 including a motor and a gear for raising and lowering the toilet seat 3 and the toilet lid 4 is provided. The toilet seat box 2 is provided with a seating sensor 6 for detecting seating on the toilet seat 3. As the seating sensor 6, various sensors such as a capacitance sensor and a limit switch for detecting up and down of the toilet seat support shaft can be used. In the toilet seat box 2, a cleaning valve device 7 (FIG. 2) is provided for supplying cleaning water to the toilet bowl 1a and cleaning the bowl.

  The toilet seat box overhanging portion 2a is provided with a human body detection sensor 10 for detecting a human body in the vicinity of the toilet body 1, and a control circuit 12 in addition to a flash switch 11 for operating the flush valve device 7. A circuit board is provided. As shown in FIG. 2, signals from the sensors 6 and 10 and the flash switch 11 are input to the control circuit 12, and the control circuit 12 controls the opening / closing drive device 5, the cleaning valve device 7, and the dimmer 13.

  Although not shown in the drawings, this toilet equipment is provided with a warm water cleaning device, a warm air fan, a toilet seat heater and the like for the human body.

  A light control body 13 is provided in a portion of the toilet lid 4 that overlaps the inner region of the inner periphery of the toilet seat 3. The light control body 13 has a structure in which a liquid crystal device having a liquid crystal layer sandwiched between transparent electrodes is laminated on a transparent resin plate. The dimmer 13 becomes transparent when a voltage is applied between the electrodes, and becomes opaque when the voltage application is canceled.

  Next, the toilet lid rotation operation and flush (toilet bowl washing) operation of this toilet equipment will be described with reference to FIG.

  When the flash switch 11 is operated, the process proceeds from step 21 to step 22 to determine whether the human body is seated on the toilet seat 3, and if it is seated, the process proceeds to step 28 and the cleaning valve device 7 is opened for a predetermined time. As a bowl wash. After the bowl cleaning is completed, the process returns to step 21.

  If no seating is detected in step 22, the process proceeds to step 23. If the toilet lid 4 is closed, the process proceeds to steps 25 and 26, where the light adjusting body 13 is made transparent and the bowl is washed. Then, the light adjusting body 13 is made opaque and the process returns to step 21.

  When the toilet lid 4 is open in Step 23, the process proceeds to Steps 24-27. After the toilet lid 4 is closed, the dimmer 13 is made transparent and washed in the same manner as described above, and then the dimmer 13 is made opaque. And return to step 21.

  Thus, in this embodiment, if the flush switch 11 is operated when the human body is not seated, the bowl washing is performed after the toilet lid 4 is closed, so that the washing noise does not spread to the surroundings.

  Moreover, since the light control body 13 is made transparent during bowl washing | cleaning, the washing | cleaning condition can be visually recognized. Moreover, since the light control body 13 is made opaque except at the time of bowl washing | cleaning, the inside of a bowl is not visible and aesthetics are good.

  It should be noted that a switch for switching between transparent and opaque of the light control body 13 may be provided so that the light control body 13 can be made transparent only when desired by the user.

  A transparent plate may be used in place of the light control body 13 so that the inside of the toilet bowl 1a can be viewed at all times. The dimmer 13 and the transparent plate may be omitted.

  If the toilet seat 3 is open when the toilet lid 4 is closed, the toilet seat 3 is also turned down together.

  Another cleaning control example will be described with reference to FIG.

If seating is detected in step 31, the process proceeds to step 32 and waits until seating is not detected. When it becomes the seating not detected, the process proceeds to step 33, the seating time returns to the step 31 is regarded as the toilet not used when shorter than the predetermined time t _0. When sitting time is _{t 0} or more, consider that there is used the toilet, the process proceeds to step 34, while waiting (step 34, 35).

  If the flash switch 11 is operated during this time, the process proceeds from step 35 to step 36, the toilet lid 4 is closed when the toilet lid 4 is open (step 37), and immediately when the toilet lid 4 is closed. Washing is performed (step 38). Thereafter, the process returns to step 31. Since the bowl washing is performed with the toilet lid 4 closed as described above, the quietness is good.

  Although the control of the light control body is omitted in FIG. 4, it may be performed in the same manner as in the above embodiment, or the light control body may be omitted or a transparent plate may be provided.

In FIG. 4, control is performed based on the detection signal of the seating sensor 6, but control may be performed based on the detection signal of the human body detection sensor 10. An example of such control is shown in FIG. In FIG. 5, if the human body detection sensor 10 detects the human body, the flow advances from step 31a to step 32a, the subsequent body is no longer detected, the process proceeds from step 32a to step 33a, or the detection time of the predetermined time t ₁ or not To determine. When the detection time is shorter than t ₁ is regarded as toilet nonuse, the flow returns to step 31a. When the detection time is t ₁ or considers that there is used the toilet, the process proceeds to step 34a, waits for a predetermined time.

  After a predetermined time has passed, the process proceeds to step 35a to check whether or not the flash switch 11 has been operated immediately before the human body is no longer detected (at the time of leaving), for example, within 1 minute before leaving, preferably within 30 seconds before leaving, If it is operated during this time, it is considered that the toilet bowl has been washed, and the process returns to step 31a. When the flush switch 11 is not operated, the process proceeds to step 36. When the toilet lid 4 is open, the toilet lid 4 is closed (step 37), and when the toilet lid 4 is closed, the bowl is washed immediately (step 37). Step 38). Thereafter, the process returns to step 31a.

  In FIG. 5, when the flash switch 11 is operated before leaving, the operations of steps 31 to 34 and 36 in FIG. 5 are executed to perform the bowl washing with the toilet lid 4 closed. May be.

  In FIG. 5, automatic flushing is not performed if the flash switch 11 is operated immediately before leaving, but if the flash switch 11 is operated during the period from human body detection to human body non-detection, Automatic cleaning may not be performed.

  The above embodiment is an example of the present invention, and the present invention may take other forms.

It is a perspective view of toilet bowl equipment concerning an embodiment. It is a control block diagram of the toilet equipment which concerns on embodiment. It is a control flowchart of the toilet equipment which concerns on embodiment. It is a flowchart which shows another example of washing | cleaning. It is a flowchart which shows another example of washing | cleaning.
