Description

Aspects of the present invention are sanitary equipment having a toilet bowl main body, an electrically controlled water supply device that supplies washing water to the toilet bowl main body, and a control device that instructs the water supply device to be driven at regular time intervals. Regarding equipment.

Generally, in public sites, toilet rooms are equipped with multiple sanitary facilities. It is known that these sanitary equipment are provided with a control device for instructing the discharge of cleaning water at regular time intervals as equipment protection cleaning in order to discharge the filth stayed in the drain pipe. (For example, Patent Document 1)

Japanese Unexamined Patent Publication No. 2010-12127

However, in the configuration of Patent Document 1, cleaning the toilet bowl at regular time intervals means that when the energization start timing is the same (breaker is turned on), water supply and drainage are performed at the same timing, and a plurality of sanitary facilities The running water pressure of the washing water supplied to the toilet bowl was reduced due to the simultaneous supply of water from the equipment (including the case where the water supply timing was slightly affected), and the drainage for each sanitary equipment was performed in the same drain pipe. In some cases, there is a problem that there is a concern about problems caused by the local increase in the amount of wastewater due to the confluence of wastewater.

The present invention has been made to solve the above problems, and prevents equipment protection cleaning from being performed from a plurality of sanitary equipment at the same timing (considering a time lag between some sanitary equipment). The purpose is.

In the sanitary equipment according to claim 1 in order to achieve the above object, the toilet bowl body, the electrically controlled water supply device that supplies washing water to the toilet bowl body, and the water supply device at regular time intervals. In the sanitary equipment having the control device instructing the drive in, the control device changes the drive timing of the water supply device at the first time after the power of the control device is turned on from the fixed time according to a predetermined condition. It is characterized by.
Therefore, even if the energization start timing (breaker is turned on) of the sanitary equipment in the toilet room is the same at the public site, the equipment protection cleaning at the first time is different for each sanitary equipment. Further, in the second and subsequent equipment protection cleanings, the timing of the equipment protection cleaning at the first time is different, so even after a certain time interval elapses, it differs for each sanitary equipment. That is, the washing water is not discharged from the plurality of sanitary equipment to each toilet body at the same time.
Therefore, when water is supplied from multiple sanitary equipment at the same time (including the case where the water supply timing is slightly affected), the hydraulic pressure of the washing water supplied to the toilet body is reduced, and the drainage of each sanitary equipment is reduced. It is possible to prevent problems caused by a local increase in the amount of drainage due to the confluence of drainage when the same drainage pipe is used.

Further, in the sanitary equipment according to claim 2, the predetermined condition is a preset random number.
Therefore, even if the energization start timing (breaker is turned on) to the sanitary equipment in the toilet room is the same at the public site, there is a possibility that the energization start timing will be the same or extremely close to each other in each sanitary equipment. Because it is low, the hydraulic pressure of the wash water supplied to the toilet bowl body due to the simultaneous supply of water from multiple sanitary equipment (including the case where the water supply timing is slightly affected) and the drainage of each sanitary equipment are reduced. It is possible to prevent problems caused by a local increase in the amount of drainage due to the confluence of drainage when the same drainage pipe is used.

Further, in the sanitary equipment according to claim 3, the predetermined condition is a history of use of the toilet bowl body after the power is turned on.
Therefore, when the toilet bowl body is used many times based on the usage history, the time until the equipment protection cleaning at the first time is shortened.
Therefore, in sanitary equipment that is frequently used and there is a high possibility that filth stays in the drainage pipe, equipment protection cleaning can be performed in a shorter time than other sanitary equipment, which is efficient.

Further, in the sanitary equipment according to claim 4, the control device has a remote controller that receives an operation from the user, and the predetermined condition is a transmission code type of the remote controller that is set in advance. To do.
Therefore, even if the energization start timing (breaker is turned on) to the sanitary equipment in the toilet room is the same at the public site, the energization start timing does not match in each sanitary equipment, and a plurality of sanitary equipment When the running pressure of the washing water supplied to the toilet bowl body due to the simultaneous water supply (including the case where the water supply timing is slightly affected) and the drainage of each sanitary equipment are performed by the same drain pipe. It is possible to prevent problems caused by a local increase in the amount of drainage due to the confluence of drainage.

According to the present invention, even when the energization start timing (breaker is turned on) of the sanitary equipment in the toilet room is the same at a public site, the equipment protection cleaning at the first time is different for each sanitary equipment. Further, in the second and subsequent equipment protection cleanings, the timing of the equipment protection cleaning at the first time is different, so even after a certain time interval elapses, it differs for each sanitary equipment. That is, the washing water is not discharged from the plurality of sanitary equipment to each toilet body at the same time.
Therefore, the running pressure of the washing water supplied to the toilet bowl body due to the simultaneous water supply from multiple sanitary equipment (including the case where the water supply timing is slightly affected) and the drainage of each sanitary equipment are the same drainage. It is possible to prevent problems caused by a local increase in the amount of drainage due to the confluence of drainage when the pipe is used.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, similar components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate.

FIG. 1 is a block diagram showing a main configuration of a sanitary equipment according to the present embodiment.
In FIG. 1, the flow of water is indicated by a solid arrow, and the flow of a signal is indicated by a broken line arrow.

As shown in FIG. 1, the sanitary equipment 1 includes a human body detection sensor 10, an operation unit 20 (remote controller), a control device 30, a water supply device 40, and a toilet bowl 50.

The human body detection sensor 10 is a pyroelectric sensor using an infrared signal, and detects a person who has entered a toilet room (not shown). The human body detection sensor 10 may be a microwave sensor such as a Doppler sensor. When a sensor using the Doppler effect of microwaves or a sensor that detects an object to be detected based on the amplitude (intensity) of the microwave transmitted and reflected is used as the human body detection sensor 10, the human body is detected. The sensor 10 can detect the presence of the user through the door of the toilet room. That is, the human body detection sensor 10 can detect the user before entering the toilet room.

The operation unit 20 is a remote controller and is installed on the wall surface of the toilet room. When operated, the operation unit 20 supplies wash water from the water supply source 60 to the toilet bowl 50 via the water supply device 40, opens and closes the toilet lid, and so on. Various functions such as can be operated.
Specifically, when the operation unit 20 detects the switch operation, it transmits a wireless control signal according to the detection. The control device 30 receives the radio control signal transmitted from the operation unit 20 and executes an operation according to the radio control signal. That is, the operation unit 20 instructs the control device 30 to execute a predetermined operation according to the operation of the user, and remotely controls the control device 40.

The control device 30 is a control circuit including an IC element, and operates the water supply device 40 based on a signal from a human body detection sensor 10 for detecting a user in front of the toilet bowl 50, an operation unit 20, and the like. Can be controlled. Further, the control device 30 controls the operation of the water supply device 40 in order to discharge the filth stayed in the drain pipe 70, and supplies the cleaning water to the toilet bowl 50 at regular time intervals as equipment protection cleaning.
Further, the control device 30 has a random number generation means 32 inside.

The water supply device 40 is a solenoid valve, and opens and closes a flow path for supplying the washing water supplied from the water supply source 60 to the toilet bowl 50 by an electric signal received from the control device 30.

Next, the operation of setting the initial equipment protection cleaning start timing (driving timing of the water supply device 40) performed in the first embodiment of the present invention will be described.
FIG. 2 is a flowchart showing an operation of setting the initial equipment protection cleaning start timing performed in the first embodiment of the present invention.

After turning on the power of the sanitary equipment 1, first, the time T1 for setting when to start the equipment protection cleaning at the first time is determined.

First, in step S01, the random number generation means 32 generates a random number R.
Specifically, the microcomputer in the control device 30 generates a random number R by using the function of a random function for generating a random value (range of 0 to 10).

In step S02, the time T1 until the equipment protection cleaning at the first time is determined by the following formula based on the random number R generated in step S01.
T1 = 120- (R × 5) (minutes)

Since the time until the equipment protection cleaning at the first time is changed, even if the energization start timing (breaker is turned on) to the sanitary equipment 1 in the toilet room is the same at the public site, the equipment protection cleaning at the first time Is different for each sanitary equipment 1. Further, even in the second and subsequent equipment protection cleanings, since the equipment protection cleaning timing at the first time is different, it is different for each sanitary equipment 1 even after a certain time interval elapses. That is, the washing water is not discharged from the plurality of sanitary equipment 1 to each toilet bowl 50 at the same time.
Therefore, the running pressure of the washing water supplied to the toilet bowl 50 due to the simultaneous water supply from the plurality of sanitary equipment 1 (including the case where the water supply timing is slightly affected) and the drainage of each sanitary equipment 1. It is possible to prevent a problem caused by a local increase in the amount of drainage due to the confluence of drainage when the above is performed in the same drainage pipe 70.

Further, since the random number R is used, it is less likely that the energization start timings of each sanitary equipment 1 are the same or extremely close to each other. The hydraulic pressure of the wash water supplied to the toilet bowl 50 due to the water supply to the toilet bowl 50, and the amount of drainage due to the confluence of the drainage when the drainage for each sanitary equipment 1 is performed in the same drain pipe 70. It is possible to prevent problems caused by the local increase in the amount of water.

In step S03, the timer 1 for timing the time T1 determined in step S02 is started.
Here, the timer 1 starts from 0 seconds.

Next, the operation of the equipment protection cleaning performed in the first embodiment of the present invention will be described.
FIG. 3 is a flowchart showing the operation of equipment protection cleaning performed in the first embodiment of the present invention.

In step S100, the control device 30 determines whether or not the equipment protection cleaning is performed at the first time.
If it is the equipment protection cleaning at the first time, the process proceeds to step S110, and if it is the second and subsequent times, the process proceeds to step S120.

In step S110, the control device 30 determines whether or not the timer 1 has elapsed the time T1 determined in step S02.
If it is determined that the lapse has passed (S110: Yes), the process proceeds to step S111, and if it is determined that the lapse has not passed (S110: No), the flow of equipment protection cleaning is repeated.

In step S111, the control device 30 starts the equipment protection cleaning at the first time.
Specifically, the control device 30 opens the water supply device 40 (solenoid valve) and discharges the washing water to the toilet bowl 50.

In step S112, the control device 30 stops the timer 1.

In step S113, the control device 30 starts a timer 2 for timing the time T2 of the equipment protection cleaning performed at regular time intervals.
Here, the timer 2 is set to 4 hours as a fixed time interval.

In step S120, the control device 30 determines whether or not the timer 2 has passed T2.
If it is determined that the lapse has passed (S120: Yes), the process proceeds to step S121, and if it is determined that the lapse has not passed (S120: No), the flow of equipment protection cleaning is repeated.

In step S121, the control device 30 starts the second and subsequent equipment protection cleanings. Specifically, the control device 30 opens the water supply device 40 (solenoid valve) and discharges the washing water to the toilet bowl 50.

In step S122, the control device 30 restarts the timer 2.

Subsequently, the operation of setting the initial equipment protection cleaning start timing performed in the second embodiment of the present invention will be described.
FIG. 4 is a flowchart showing an operation of setting the initial equipment protection cleaning start timing performed in the second embodiment of the present invention.
Since the operation of the equipment protection cleaning performed in the second embodiment of the present invention is the same operation as the operation shown in FIG. 3 performed in the first embodiment of the present invention, the description thereof will be omitted.

The operation of setting the initial equipment protection cleaning start timing performed in the first embodiment of the present invention uses the random number R by the random number generating means 32, but in the second embodiment of the present invention, the user is large. Use the number of times the toilet bowl 50 is used.
After the power is turned on to the sanitary equipment 1, first, the number of times N of the user has used the toilet bowl 50 is set to 0, and the elapsed time is measured by a timer 3 (not shown) inside the control device 30.

In step S10, the control device 30 determines whether or not the elapsed time of the timer 3 exceeds one hour.
If it is determined that the elapsed time has been exceeded (S10: Yes), the process proceeds to step S11, and if it is determined that the elapsed time has not been exceeded (S10: No), step S06 is repeated.

In step S11, the control device 30 reads the number of times N of the toilet bowl 50 has been used by the user within one hour stored in the microcomputer.

In step S12, the control device 30 determines the time T1'until cleaning at the first time by the following formula based on the number of uses N read in step S11.
T1'= 60- (N x 5) (minutes)
If the time T1'before cleaning at the first time is negative, it is uniformly set to 0 minutes.

Therefore, when the number of times N of the toilet bowl 50 is used is large, the time until the equipment protection cleaning at the first time is shortened.
Therefore, in the sanitary equipment 1 having a large number of uses N and a high possibility that filth stays in the drainage pipe, the equipment protection cleaning can be performed in a shorter time than the other sanitary equipment 1, which is efficient.

In step S13, the control device 30 starts the timer 1 for timing the time T1'determined in step S11.

Subsequently, the operation of setting the initial equipment protection cleaning start timing performed in the third embodiment of the present invention will be described.
FIG. 5 is a flowchart showing an operation of setting the initial equipment protection cleaning start timing performed in the third embodiment of the present invention.
Since the operation of the equipment protection cleaning performed in the third embodiment of the present invention is the same operation as the operation shown in FIG. 3 performed in the first embodiment of the present invention, the description thereof will be omitted.

The operation of setting the initial equipment protection cleaning start timing performed in the first embodiment of the present invention uses the random number R by the random number generating means, but in the third embodiment of the present invention, the transmission code type of the remote controller Use (0 to 20).

First, in step S20, the control device 30 reads the code C of the remote controller body.
Specifically, in the sanitary equipment 1, the operation unit 20 and the control device 30 store common identification information. The plurality of sanitary equipment 1 provided in the toilet room store different identification information. That is, the code C of the remote controller body is different for each sanitary equipment 1. The code C of the main body, which is the identification information, is read.

In step S21, the time T1 until the equipment protection cleaning at the first time is determined by the following formula based on the code C of the main body read in step S20.
T1 ″ = 120- (C × 5) (minutes)

Therefore, even if the energization start timing (breaker is turned on) to the sanitary equipment 1 in the toilet room is the same at the public site, the energization start timing does not match in each sanitary equipment 1, and a plurality of sanitations are provided. The dynamic pressure of the washing water supplied to the toilet bowl 50 due to the simultaneous supply of water from the equipment 1 (including the case where the water supply timing is slightly affected) and the drainage of each sanitary equipment 1 are the same drain pipe 70. It is possible to prevent problems caused by a local increase in the amount of drainage due to the confluence of drainage in the case of the above.

In step S22, the timer T1 for timing the time T1 determined in step S02 is started.
Here, the timer T1 starts from 0 seconds.

The embodiments of the present invention have been described above. However, the present invention is not limited to these descriptions. Those skilled in the art with appropriate design changes regarding the above-described embodiment may also be used.
As long as it has the features of the present invention, it is included in the scope of the present invention. For example, the variable generation means included in the control device 30 is not limited to the examples, and can be appropriately changed, such as using the sitting time of the user on the toilet bowl 50 as the variable generation means.
