Description

[Detailed Description of the Invention] Industrial Field of Application: The present invention relates to a toilet seat cleaning device that is particularly suitably installed in Western-style flush toilets that require a fee.

Conventional technology: For paid toilets equipped with Western-style flush toilets, it is especially important to take care not to cause discomfort to users, and for the toilet seats, a method of using disposable cover paper or a purification method by flushing is adopted. be done.

Problems the invention aims to solve: The method of purifying the toilet seat by flushing is superior to the method of using disposable paper covers because the seat is kept in a clean state before use, but it is not currently in practical use. The following operations are performed: the operation of raising the toilet seat, the operation of carrying the toilet seat into the back room of the toilet room, the operation of washing the toilet seat while rotating it, the operation of drying the toilet seat after washing, and the operation of returning the toilet seat to its normal state. The mechanism for sequentially performing these steps is quite complex.

Means for solving the problem: The present invention is to arrange a Western-style flush toilet with the rear end of the toilet close to the toilet wall, and to install the toilet in the back room of the toilet room, which is separated from the toilet room by the toilet wall. A toilet seat with an extension that enters into the toilet room is provided, and a toilet seat advancement/retraction device, a flushing device using a rotating brush, a draining unit, and a drying blower are housed in the back room of the toilet room, and a signal is emitted when a user leaves the seat. The toilet seat is characterized by being provided with a control device that performs control to move the toilet seat backward into the rear chamber of the toilet room while operating the flushing device, and then advance the toilet seat to the use position while operating the drying blower.

The signal is generated by a switch activated by the weight of the user, for example a pressure sensitive switch.
It is desirable that the operation of flushing water into the toilet bowl be performed by the control device as well as by the user's operation.

Effect: In the above-mentioned system, the toilet seat is purified in the process of linear movement given to the toilet seat, and the amount of water used to clean the toilet seat and the amount of air sent to dry the valve seat are reduced. is relatively small, and purification is completed in a relatively short time.

Embodiment: In FIG. 1, 1 is a toilet room, 2 is a rear room of the toilet room, and 3 is a partition wall that partitions the toilet room 1 and the back room 2. The term "behind" here refers to the toilet bowl 4 as a reference. The toilet seat 5 has an extension 6 that enters into the rear chamber 2 of the toilet room, and is moved backward into the rear chamber 2 by motor-driven rollers 7. In order to minimize the overall length of the toilet seat 5 with the extension 6, the toilet bowl 4 is provided close to the partition wall 3. 8 and 9 are instructions for the toilet seat.

The toilet seat 5 is washed and purified by a flushing device 10 provided in the rear chamber 2, and is moved back to a position where its front end exceeds the draining portion 11. The washing device 10 uses a rotating brush, and after washing the toilet seat 5, the brush stops rotating and is raised to a non-operating position.

After the toilet seat 5 has been washed, it is dried by the blower 12 when it is moved forward to return to its normal state.

13 is a water supply valve to the washing device 10, 14 is a pressure sensitive switch that detects when the user leaves the seat, and 15 is a pressure sensitive switch that detects that the valve seat 5 has reached the end of the backward stroke.

Control device 16 for the various elements pointed out above
This is shown in FIGS. 2 and 3, divided into a process in which the toilet seat 5 is retreated into the rear chamber 2 and a process in which the toilet seat 5 is advanced and returned to its normal state.

Figure 2 shows the predetermined time after the user leaves the seat (for example, 15
The operation according to the signal S ₁ which is valid after (seconds) is indicated. That is, when the signal S ₁ is issued, the water supply valve 1
The electromagnetic actuator MV-13 of No. 3 is operated to open the valve, and the brush drive motor M-10 of the flushing device 10 starts rotating, and at the same time, the motor M-7 that drives the roller 7 moves the toilet seat 5 backward. The toilet seat 5 is started to rotate as if it were to be rotated, and the toilet seat 5 is washed and purified during the backward stroke.

A signal _S2 for advancing the toilet seat 5 is issued to a pressure sensitive switch 15 which detects the end of the backward stroke of the toilet seat 5. Signal S ₂ can be generated by optical or electromagnetic means. The toilet seat 5 moves forward when the signal _S2 is generated.

FIG. 3 shows the operation of each part due to the generation of signal _S2 . That is, when the signal _S2 is issued, the electromagnetic actuator MV-13 closes the water supply valve 13, the brush drive motor M-10 of the flushing device 10 stops, and the brush rises above the toilet seat 5 to drive the roller 7. The motor M-7 rotates in the direction of advancing the toilet seat 5, and at the same time, the motor M-1 of the drying blower 12 rotates.
2 starts rotating. When the toilet seat 5 returns to its normal state, each part is reset by the signal _S3 issued by the pressure sensitive switch 14. The signal _S3 also operates the toilet flushing water discharge valve MV-5.

In addition to washing with water, it is desirable to perform sterilization, and a roller for applying disinfectant alcohol or the like is provided near the draining section 11.

Effects of the invention: This invention enables the use of a Western-style toilet without discomfort. Currently, Western-style toilets that clean and purify the toilet seat are not installed in Japan, and the reason why they are rarely seen in other countries is because the operating mechanism of such toilet seats is complicated, and the disadvantages in terms of cost and installation space are large. I think that the. The present invention provides a solution to this problem, and the present invention consists of placing some simple devices along the toilet seat which is given linear movement.

[Brief explanation of drawings]

Figure 1 is a diagram showing the mechanism of the toilet seat purifying device according to the present invention, and Figures 2 and 3 explain the operation of the control device that controls each part of Figure 1, dividing it into the backward stroke and forward stroke of the toilet seat. It is an explanatory diagram.
