機能を備えた自動洗浄装置の提供を目的とする。Conventionally, automatic cleaning equipment did not have an antifreeze function. Therefore, measures to prevent freezing are necessary in cold regions. As a measure to prevent freezing, the residual water remaining in the washing water supply and drainage channel from the water supply pipe to the drainage channel via the urinal or washbasin should be discharged to a freeze-free area such as underground, or a small amount of water should be placed in this washing water supply and drainage channel. 2- There is a method of constantly running a large amount of water. However, draining the residual water requires a lot of time and effort, and constantly running water has the problem of increasing the amount of wasted washing water. The above problem is particularly serious in public facilities equipped with a large number of urinals and wash basins. SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide an automatic cleaning device having an anti-freeze function that periodically supplies anti-freeze wash water depending on the ambient temperature of the equipment.

防止する。The apparatus of the present invention will be explained based on embodiments shown in the drawings. (First Embodiment) FIG. 1 is a block diagram showing a first embodiment of the present invention device installed in a urinal facility, and FIG. 2 is a flowchart showing the control operation of the same embodiment. The device 10 of the present invention cleans by inputting a human body detection sensor 2 that detects a user, a cleaning valve 3 provided in the middle of a cleaning water supply pipe 6 connected to a urinal, and a detection signal from the human body detection sensor 2. A control circuit 14 outputs an opening/closing signal to the toilet valve 3, and a temperature detector 4-11 detects the temperature inside the toilet, which is the ambient temperature of the equipment. This control circuit 14 includes a human body detection circuit 19 that controls the opening and closing of the cleaning valve 3 based on the human body detected by the human body detection sensor 2, a timer circuit 15 that controls the opening and closing of the cleaning valve 3 every cycle, and a temperature detection circuit that controls this cycle. Vessel 1
A cleaning cycle setting circuit 12 is incorporated to set the anti-freezing time according to the detected temperature. A power supply circuit 18 is connected to the control circuit 14 and the cleaning valve 3, respectively. Control circuit 14 operates as shown in the flowchart of FIG. First, when the control circuit 14 receives a start command using a push button switch or the like, it resets the timer flag of the timer circuit 15 and the human body flag of the human body detection circuit 19 to the O state. The cleaning cycle setting circuit 12 detects the detected temperature R of the temperature detector 11.
is input, the detected temperature R and the condition temperature C (Cr,
C2, C3), the antifreeze time D (Dl,
C2, C3) or equipment maintenance time E is determined. The condition temperature C has a relationship of CI <02 <03, and the time period E has a relationship of Di <C2<C3<E. The antifreeze time is the interval required to prevent the urinal equipment from freezing at the condition temperature C, and is determined in advance through experiments or the like. Equipment maintenance time E refers to the interval required to replenish evaporated water so as not to lose the water sealing function of the drain trap provided in the urinal. Incidentally, in determining the period S, in this embodiment, the condition temperature C is defined stepwise as 01, C2, and C3, but the period S is not limited to this in any way, and the period S is determined depending on the time. It is also possible to find E as a function of the conditional temperature C, and then substitute the detected temperature R into the conditional temperature C of this function to calculate E. Furthermore, if it is not necessary to replenish water to the drain trap, the equipment maintenance time E may be set to infinity. When the timer circuit 15 receives the signal from the cleaning cycle setting circuit 12, the timer flag is initially in the O state, so
After starting the timer body provided in the timer circuit 15 and setting the timer flag to 1, a signal is output to the human body detection circuit 19. When receiving the signal from the cleaning cycle setting circuit 12 again, the timer circuit 15 compares the elapsed time value T from the timer start with the cycle S determined by the cleaning cycle setting circuit 12 since the timer flag is 1. do. When the elapsed time value T does not exceed the period S (T<S), the signal is output as is to the human body detection circuit 19, and conversely, when the elapsed time value T is greater than the period S (
If T≧S), cleaning is instructed, the timer body is reset, the timer flag is set to O, and a signal is output to the human body detection circuit 19. Furthermore, the timer circuit 15 receives a return signal from the cleaning cycle setting circuit 12 and repeats the above routine. When flushing is commanded from the timer circuit 15, the flushing valve 3 (see FIG. 1) opens for a set time and supplies flushing water to the urinal via the flushing water supply pipe 6. Supplied washing water (to prevent freezing with running water action,
Or refill the urinal drain trap. The human body detection circuit 19, to which the output signal of the timer circuit 15 is first input after the start command, detects a human body as No (i.e., there is no user in front of the urinal) based on the detection signal from the human body detection sensor 2. When this is confirmed, the reset human body flag is in one state of 0, so the signal is returned to the cleaning cycle setting circuit 12. The human body detection circuit 19 receives the signal from the timer circuit 15 again, and when it confirms that the human body has been detected as YES (that is, there is a user in front of the urinal), the human body flag is set to O, so the human body flag is set to 1. After instructing pre-cleaning, a signal is returned to the cleaning cycle setting circuit 12. The cleaning valve 3 (see Figure 1) that receives the command for preliminary cleaning opens for a set time and supplies preliminary cleaning water to the urinal via the cleaning water supply piping 6. Perform cleaning. The human body detection circuit 19 in use confirms that the human body has been detected as YES, and since the human body flag is 1, the routine of returning the signal to the cleaning cycle setting circuit 12 is repeated. When the errand is finished and the user is no longer present, the human body detection circuit 19 confirms that the human body detection is No, and since the human body flag is in the state of 1, the human body flag is set to the state of O, and the main cleaning is commanded. After resetting the timer body of the timer circuit 15 and setting the timer flag to 0, the signal is returned to the cleaning cycle setting circuit 12. Here, the reason why the timer start and the timer flag are set to O is that the main cleaning can be substantially regarded as antifreeze cleaning. The cleaning valve 3 (see FIG. 1) that receives the main cleaning command opens for a set time and supplies main cleaning water to the urinal via the cleaning water supply pipe 6. As described above, the device 10 of the present invention determines the period S for controlling the opening and closing of the cleaning valve 3 to be a time corresponding to the ambient temperature of the urinal equipment, and opens the cleaning valve 3 for a predetermined time every period to prevent freezing. Prevent urinal equipment from freezing by cleaning or maintaining the equipment. Note that since preliminary cleaning is not essential, the preliminary cleaning command may be omitted. (Second Embodiment) Fig. 3 is a block diagram showing a second embodiment of the present invention device installed in a handwash facility or washbasin facility (hereinafter simply referred to as "handwash facility"), and Fig. 4 is the same. 2 is a flowchart showing the control operation of the embodiment.The device 20 of the present invention includes a human body (hand) detection sensor 2 that detects a user's hand held out below a faucet 27 of a hand wash basin 25.
2, a cleaning valve 23 provided in the middle of the cleaning water supply pipe 26 connected to the faucet 27, and a human body (hand) detection sensor 2.
The control circuit 34 inputs the detection signal No. 2 and outputs an opening/closing signal to the cleaning valve 23, and a temperature detector 31 detects the temperature inside the washroom, which is the ambient temperature of the equipment. This control circuit 34 includes a human body detection circuit 39 that controls the opening and closing of the cleaning valve 23 based on the human body detected by the human body detection sensor 22, a timer circuit 35 that controls the opening and closing of the cleaning valve 23 every cycle, and a temperature detection circuit that controls this cycle. A cleaning cycle setting circuit 32 that sets the antifreeze time according to the detected humidity of the container 31.
It incorporates. Control circuit 34 and cleaning valve 23
A power supply circuit 38 is connected to each of them. Regarding the contents of the cleaning cycle setting circuit 32 and the timer circuit 35,
Since they are substantially the same as the cleaning cycle setting circuit 12 and the timer circuit 15 in the first embodiment, their explanation will be omitted. The control circuit 34 operates as shown in FIG. 4, but the difference from the first embodiment is the human body detection circuit 39. When the human body detection circuit 39 receives the output signal of the timer circuit 35 and confirms that the human body is detected as No (i.e., water spouting is not required) based on the detection signal from the human body detection sensor 22, After issuing a command to stop cleaning, a signal is returned to the cleaning cycle setting circuit 32. Human body detection circuit 39
The signal is input from the timer circuit 15 again, and the human body (
When the hand) detection is confirmed as YES (that is, the state that requires water spouting), a command is given to maintain cleaning (faucet water spouting), the timer body of the timer circuit 35 is reset, and the timer flag is set to the O state. The signal is returned to the cleaning cycle setting circuit 32. The cleaning valve 23 (see FIG. 3), which has received a command to maintain cleaning, is opened and remains open until the command to stop cleaning is received. The device 20 of the present invention determines the cycle S for controlling the opening and closing of the cleaning valve 23 to be a time corresponding to the ambient temperature of the wash basin equipment, and opens the cleaning valve 23 for a predetermined time every cycle to perform antifreeze cleaning or maintain the equipment. Clean and prevent handwash equipment from freezing.
