は不十分であつた。(Problem that the invention aims to solve) However, in the conventional toilet bowl cleaning device as mentioned above, after the human body is sensed and pre-flushing is performed, flushing water is not supplied until the person leaves the toilet bowl, so the inner surface of the bowl is When wet with urine, this vaporizes and generates an odor, and there is a risk that the urine will bounce off the inner surface of the bowl and splash onto the user, so it is extremely difficult to bring odor components and dust into the workplace. It was inadequate as a toilet device for IC factories, food factories, etc.
そこで、便器使用中に亙り電磁弁を開弁し続け
て洗浄水を供給し続けることが考えられるが便器
使用時間が長くなる程、洗浄水の消費量が多く不
経済であるという問題点を残していた。 Therefore, one idea is to keep the solenoid valve open while the toilet is in use to continue supplying flushing water, but this leaves the problem that the longer the toilet is in use, the more flushing water is consumed, which is uneconomical. was.

うになつている。 The urinal 1, as shown in FIGS. 2 to 4,
A sensing unit 2 that senses a human body, a control unit 3 that operates based on a sensing signal from the sensing unit 2, and a solenoid valve 4c that is opened and closed by an output signal from the control unit 3.
In detail, the opening 1a of the urinal 1
A water passage 4a is formed along the entire circumference, and this water passage 4
Water supply pipe 4b leading out water a to the outside of clean room A
is connected to the water supply source via the water supply pipe 4.
b is provided with a solenoid valve 4c, and the solenoid valve 4c is electrically connected to the control unit 3, and the solenoid valve 4c is periodically opened in response to a command from the control unit 3 to flow the water from the water supply pipe 4b to the water passage 4a. Washing water is supplied intermittently, and the washing water flows along the inner wall of the urinal 1 from a large number of water holes 4d opened in the bottom wall of the water passage 4a, thereby washing the inside of the urinal 1. Washing water and urine from the washing device are discharged from the urinal 1 to the outside of the clean room A via a drain trap 5a and a drain pipe 5b.

である。 The sensing unit 2 is composed of a photoelectric sensor, and detects the human body standing in front of the urinal 1 when using the toilet, and sends the sensing signal to the control unit 3, making the control unit 3 recognize the start of the toilet. Urinal 1 formed so as not to obstruct the flow of clean air inside A
It is attached almost flush with the upper front wall 1b of the. As shown in FIG. 5, the mounting structure of the sensing part 2 is as shown in FIG.
At the same time, the light emitting and light receiving plate 2a at the front end of the sensing section is brought into contact with the outer surface of the front wall 1b, while the mounting screw shaft 2b at the rear end is attached to the inner surface of the front wall 1b with a bracket 6a and a nut 6b. It is fixed via the

置の無用な作動が防止されるものである。 That is, when the user stands in front of the urinal 1, the sensing section 2 senses the human body and sends the sensing signal to the control section 3. This sensing signal is canceled if the output is within a predetermined period of time, for example, 3 seconds, thereby preventing unnecessary operation of the toilet bowl cleaning device.

周期的な開閉動作が用便時間内で複数回繰り返さ
れる。 When the sensing signal is input to the control unit 3 for 3 seconds or more, the solenoid valve 4c of the toilet bowl cleaning device opens in response to a command from the control unit 3, and the toilet bowl B starts to be flushed before using the toilet. The opening time of the solenoid valve 4c is 1 second,
After the opening time has elapsed, the solenoid valve 4c closes and opens again 6 seconds later, and such periodic opening and closing operations of the solenoid valve 4c are repeated multiple times during the toileting time.
前記電磁弁４ｃの開弁及び閉弁時間は制御部３

作するものである。 The opening and closing times of the solenoid valve 4c are determined by the control unit 3.
The solenoid valve 4c is counted by a timer, and the solenoid valve 4c opens and closes at intervals of a set time in the control section.

である。 By the periodic opening/closing operation of the solenoid valve 4c, an appropriate amount of flushing water is intermittently supplied into the urinal 1 from before the start of urination to after the end of the urination, and water is constantly supplied to the inner wall of the urinal 1. It forms a film and cleans without leaving urine components behind, and there is no odor. That is, even if the user leaves the urinal 1 after urinating and the input of the sensing signal from the sensing section 2 to the control section 3 stops, the supply is continued by opening the solenoid valve 4c before stopping. The flushed water cleans the inside of the urinal 1.
（考案の効果）
本考案は、上記せる如き構成を有するため下記
の効果を奏する。(Effects of the invention) Since the invention has the above configuration, it has the following effects.

る。 While the toilet is in use, flushing water is supplied to the toilet bowl intermittently, and a water film is formed on the inner surface of the bowl of the urinal, and this water film prevents urine from adhering to the inner surface of the bowl and from splashing back. Therefore, while the toilet is in use, the total supply amount can be reduced while continuing to supply flushing water and creating a water film on the inner surface of the bowl.

なり節水が図れて経済的である。 Therefore, compared to conventional systems in which flushing water is not supplied until the user leaves the toilet bowl after sensing a human body and pre-flushing, urine may adhere to the inner surface of the bowl after pre-flushing and generate odor. In addition, the droplets do not bounce back onto the user, making it effective as a toilet device in clean rooms that require particularly high levels of cleanliness. It is economical as it consumes less water and saves water.
