Description

The present invention relates to a urinal device that cleans a bowl portion with washing water.

Conventionally, a flush toilet that supplies washing water to the bowl portion after use is known. In flush toilets, a trap that fills the sealed water is connected to the downstream of the bowl, and urine is stored in the sealed water after the user urinates. At this time, by supplying the washing water to the bowl part, the urine adhering to the bowl part is washed away, and the sealing water containing the urine is replaced with the washing water. As a result, the urine remaining in the bowl etc. is washed away before the germs in the urine proliferate significantly, and the generation of ammonia and the generation of urine stones are suppressed to prevent the generation of odor and the clogging of the drain pipe by the urine stones. doing.

By the way, in response to the growing environmental awareness in recent years, high water-saving performance is required even for urinals. However, in a flush toilet as described above, a single flush to the bowl part flushes the urine adhering to the bowl portion, replaces and discharges the urine in the trap, and flushes the urine in the drain pipe. Therefore, it is difficult to maintain the hygiene of urinals simply by reducing the amount of wash water used.

As an example of a urinal device that meets the demand for high water-saving performance, tap water containing chloride ions is electrolyzed by an electrolytic cell, and hypochlorous acid water produced by electrolysis is used as wash water. There is one (Patent Document 1). This urinal device can efficiently maintain the hygiene of the urinal by discharging hypochlorous acid water having a bactericidal action into the bowl portion as washing water.

Japanese Unexamined Patent Publication No. 2014-173270

In the process of electrolyzing tap water, calcium and the like adhere to the electrode plate provided inside the electrolytic cell. Therefore, the more electrolyzed the electrode plate is, the more deposits are attached and the lower the performance of the electrode plate is. In the urinal device of Patent Document 1 described above, the bowl portion is washed with hypochlorous acid water every time the user uses it, and regular cleaning with hypochlorous acid water is performed at regular intervals. Therefore, by frequently generating hypochlorous acid water by electrolysis, the catalyst layer is peeled off from the surface of the electrode plate, the electrode plate is consumed, and calcium adheres, resulting in significant deterioration of the electrolytic cell. It will promote.

The present invention has been made to solve the above-mentioned problems, and in a urinal device for washing a bowl portion with washing water, it is efficient to wash with functional water having a bactericidal action at an appropriate timing. The purpose is to maintain the hygiene of the urinal.

The urinal device according to one aspect of the present invention is a small urinal device that performs a cleaning operation of supplying either water supplied from a water supply source or functional water capable of decomposing ammonia to the bowl portion as cleaning water after use. A urinal device, provided with an electrolytic tank having an electrode, and a functional water generating means for generating hypochlorous acid water as the functional water from the water supplied from the water supply source by energizing the electrodes . A washing water supply means for supplying the washing water to the bowl portion and a control means for controlling the washing operation are provided, and the control means responds to the usage status of the urinal device when the washing operation is performed. It is determined whether the water supplied from the water supply source or the functional water is supplied from the washing water supply means to the bowl portion, and the control means is further washed with the hypochlorite water. When performing the operation, the current value flowing through the electrode is changed according to the frequency of use of the urinal device.

According to the urinal device configured in this way, it is determined whether the water supplied from the water supply source or the functional water is supplied to the bowl portion according to the usage status of the urinal device. Usually, by generating functional water capable of decomposing ammonia from water supplied from a water supply source, electric power is consumed and deterioration of the functional water generating means is promoted. Therefore, according to the urinal device configured in this way, by performing the cleaning with the functional water at an appropriate timing in the cleaning operation performed after use, the urinal can be efficiently cleaned as compared with the case where the cleaning with the functional water is performed every time. Hygiene can be maintained. Further, by supplying the hypochlorous acid water as the functional water generated by the functional water generating means to the bowl portion, the hygiene of the urinal can be efficiently maintained. In addition, when the urinal device is used frequently, the number of washings is large and the amount of ammonia produced is small, so the current value flowing through the electrodes is lower and the concentration of hypochlorous acid water is lower than when the urinal device is used less frequently. To do. Normally, the deterioration of the electrolytic cell accelerates as the value of the current flowing through the electrodes increases. That is, by changing the current value flowing through the electrode according to the frequency of use of the urinal device in the cleaning operation, the concentration of hypochlorous acid water can be appropriately changed and the deterioration of the electrolytic cell can be suppressed.

Further, in the urinal device according to one aspect of the present invention, when the control means performs the cleaning operation, if the frequency of use of the urinal device is less than the first predetermined frequency, the functional water is used. When the urinal device is used more frequently than the first predetermined frequency while being supplied from the washing water supply means to the bowl portion, the water supplied from the water supply source is supplied from the washing water supply means. It may be supplied to the bowl portion.

According to the urinal device configured in this way, when the urinal device is used infrequently, functional water capable of decomposing ammonia is supplied from the washing water supply means to the bowl portion during the washing operation. When the urinal device is frequently used, the water supplied from the water supply source is supplied to the bowl portion from the washing water supply means. Normally, ammonia is produced by the decomposition of urobilin, which is excreted as urine from the human body, by bacteria over several tens of minutes to several hours. Therefore, when the urinal device is used frequently, the number of washings is large, so that the time for urobilin to change to ammonia is not sufficient and the amount of ammonia produced is small, but if the urinal device is used less frequently. Since the washing interval is long, the amount of ammonia produced increases because there is sufficient time for the urobilin to change to ammonia. As a result, the hygiene of the urinal can be maintained more efficiently than in the case of cleaning with the functional water every time by performing the cleaning with the functional water at an appropriate timing in the cleaning operation.

Further, in the urinal device according to one aspect of the present invention, the control means may perform periodic cleaning for supplying the functional water to the bowl portion at a time determined according to the usage status of the urinal device. Good.

According to the urinal device configured in this way, a time is set according to the usage status of the urinal device, and regular cleaning with functional water is performed at the set time. As a result, the hygiene of the urinal can be efficiently maintained by performing regular cleaning with functional water at an appropriate timing.

Further, in the urinal device according to one aspect of the present invention, the control means may perform the periodic cleaning when the elapsed time after the previous use of the urinal device exceeds a predetermined predetermined time. Good.

According to the urinal device configured in this way, when a predetermined time is exceeded from the previous use, that is, when the predetermined time is exceeded after the previous cleaning of the bowl portion, periodic cleaning with functional water is performed. As a result, the hygiene of the urinal can be efficiently maintained by performing regular cleaning with functional water at an appropriate timing.

Further, in the urinal device according to one aspect of the present invention, the control means uses the urinal device frequently when the elapsed time after the previous use of the urinal device exceeds a predetermined predetermined time. If is less than the second predetermined frequency, the periodic cleaning may be performed.

According to the urinal device configured in this way, when the urinal device is used less frequently when the predetermined time has been exceeded since the previous use, that is, when the predetermined time has been exceeded since the bowl portion was washed last time. Periodically wash with functional water (if it is less than the second predetermined frequency). As a result, the hygiene of the urinal can be efficiently maintained by performing regular cleaning with functional water at an appropriate timing.

Further, in the urinal device according to one aspect of the present invention, the control means may set the frequency of performing the periodic cleaning according to the frequency of use of the urinal device at a predetermined time.

According to the urinal device configured in this way, the frequency of performing regular cleaning is set at a predetermined time, and if the urinal device is used frequently at that time, the frequency of performing regular cleaning is set low. If the urinal device is used infrequently, set the frequency of regular cleaning to be high. As a result, the hygiene of the urinal can be efficiently maintained by appropriately setting the frequency of performing regular cleaning according to the frequency of use of the urinal device.

Further, in the urinal device according to one aspect of the present invention, the functional water generating means includes an electrolytic cell having an electrode, and when the electrode is energized, the functional water is supplied from the water supply source. The control means may change the value of the current flowing through the electrode according to the frequency of use of the urinal device when the periodic cleaning is performed with the hypochlorite water. Good.

According to the urinal device configured in this way, in regular cleaning, when the urinal device is frequently used, the number of cleanings is large and the amount of ammonia produced is small, so that the current flows through the electrodes as compared with when the frequency of use is low. Lower the current value and lower the concentration of hypochlorite water. As a result, the concentration of hypochlorous acid water can be appropriately changed by changing the value of the current flowing through the electrodes depending on the frequency of use of the urinal device in regular cleaning, and deterioration of the electrolytic cell can be suppressed.

According to the present invention, in a urinal device for cleaning a bowl portion with washing water, the hygiene of the urinal can be efficiently maintained by performing cleaning with functional water having a bactericidal action at an appropriate timing.

<Composition of urinal device>
First, the urinal device according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing a configuration of a urinal device according to the present embodiment. FIG. 2 is an overall perspective view of the urinal body according to the present embodiment.

As shown in FIGS. 1 and 2, the urinal device 1 includes a urinal body 10, a human body detecting means 20, a flow path switching valve 30, a functional water generating means 40, and a first washing water supply means 50. A second wash water supply means 60 and a control means 70 are provided.

The urinal body 10 has a bowl portion 11 and a drain trap 12. The drain trap 12 is provided on the downstream side of the bowl portion 11 and forms a sealing water inside the drain trap 12. As a result, the drain trap 12 can prevent bad odors and pests from invading the toilet room or the like from a horizontal drainage pipe (not shown) provided behind the urinal device 1.

The human body detecting means 20 is an infrared light emitting / receiving type ranging sensor capable of detecting a user who is in front of the urinal body 10, that is, a user who is located at a position separated forward from the urinal body 10.

The flow path switching valve 30 is in a state where the water supplied from the water supply source 5 (for example, a water supply or a tank) is guided to the first washing water supply means 50 based on the signal transmitted from the control means 70, and the supply. The state in which the water supplied from the water source 5 is guided to the second washing water supply means 60 is switched.

The first washing water supply means 50 has a spreader 51, and supplies water supplied from the water supply source 5 via the flow path switching valve 30 to the bowl portion 11 of the urinal body 10.

The second washing water supply means 60 has a water sprinkling section 61, and the water supplied from the water supply source 5 via the flow path switching valve 30 and dropletized water is sprinkled from the sprinkling section 61 to the urinal body. It is supplied to the bowl portion 11 of 10. The water supplied from the sprinkler portion 61 to the bowl portion 11 of the urinal body 10 can dissolve ammonia. The diameter of the dropletized water sprinkled by the second washing water supply means 60 is, for example, about 10 micrometers (μm) or more and 12000 μm or less.

By controlling the flow path switching valve 30, the control means 70 supplies wash water from the spreader 51 of the first wash water supply means 50 or the sprinkler 61 of the second wash water supply means 60 to the urinal body 10. Control the cleaning operation. The control means 70 includes a storage unit 71 and a timer 72. The storage unit 71 stores information about the number of times the urinal device 1 has been used within at least the last 24 hours (1 day). The term "use of the urinal device 1" as used herein means that the user approaches the front of the urinal body 10 and then stands still to urinate in front of the urinal body 10 and finishes urinating. The operation of the user from the front of the urinal body 10 until it is separated. The human body detecting means 20 detects the movement of the user, and the human body detecting means 20 sends a signal to the control means 70, so that the storage unit 71 of the control means 70 stores the number of times the urinal device 1 has been used as one time. To the toilet.

Here, the mechanism of ammonia generation is, for example, as follows.
That is, when urine is urinated in the toilet bowl, the urine adheres to the surface of the toilet bowl or stays in the sealing water (retained water) of the trap portion. General bacteria present in the air or on the surface of the toilet bowl adhere to the accumulated urine. General bacteria absorb nutrients from urine, activate the activity of releasing urease enzyme, and promote the suppression of urea decomposition by urease enzyme. Urea is decomposed into ammonia and carbon dioxide, and the ammonia contributes to the malodor. In addition, when the hydrogen ion concentration (pH) of the decomposition product is biased to alkaline due to the generated ammonia and the pH is biased to alkaline beyond 8.0 to 8.5, the calcium ions dissolved in the urine become difficult. It becomes a soluble calcium compound (calcium phosphate, etc., also generally called urinary stone). This urinary stone becomes a hotbed of bacteria, and the process so far is repeated at an accelerating rate to generate more ammonia. It takes several tens of minutes to several hours after the urine stays in the sealed water for the pH to rise.

The functional water generating means 40 can generate functional water from the water supplied from the water supply source 5 via the flow path switching valve 30 based on the signal transmitted from the control means 70. Fuctional water can dissolve and decompose ammonia.

The functional water generating means 40 includes an electrolytic cell 41 having an anode plate 42 and a cathode plate 43 inside as electrodes, and energizes the anode plate 42 and the cathode plate 43 based on a signal transmitted from the control means 70. It can electrolyze tap water and miscellaneous water flowing inside. Here, tap water contains chloride ions. Chloride ions are contained in water sources (for example, groundwater, dam water, river water, etc.) as salt (NaCl), calcium chloride (CaCl ₂ ), and the like. Therefore, hypochlorous acid water is generated by electrolyzing chloride ions. As a result, the water electrolyzed by the functional water generating means 40 (electrolyzed water) is changed to functional water containing hypochlorous acid (hypochlorous acid water).
Hypochlorite water functions as a deodorant component or a bactericidal component. Hypochlorite water can dissolve ammonia, decompose it, or sterilize general sterilization.

When the functional water generating means 40 generates the functional water based on the signal transmitted from the control means 70, the second washing water supply means 60 sprinkles the functional water generated by the functional water generating means 40. It is supplied from 61 to the bowl portion 11 of the urinal body 10.
On the other hand, when the functional water generating means 40 does not generate the functional water, the second washing water supply means 60 is the water supplied from the water supply source 5 via the flow path switching valve 30 and the functional water generating means 40. (This water is called fresh water. Fresh water is tap water or miscellaneous water supplied from the water supply source 5.) Is supplied from the sprinkler portion 61 to the bowl portion 11 of the urinal body 10.

According to the present embodiment, the second washing water supply means 60 supplies water to the bowl portion 11 of the urinal body 10 and exists around the ammonia generated inside the bowl portion 11 and the bowl portion 11. Dissolves and decomposes at least one of the ammonia. The ammonia existing around the bowl portion 11 means, for example, ammonia floating around the bowl portion 11 or ammonia floating around the bowl portion 11. As a result, the second washing water supply means 60 can suppress the odor caused by ammonia generated from the urinal device 1.
In addition, the first washing water supply means 50 can supply water to the bowl portion 11 of the urinal body 10 to remove urine adhering to the urinal body 10 and remove foreign matter such as body hair. Further, the first washing water supply means 50 can supply water to the drain trap 12 of the urinal body 10 and replace the sealing water inside the drain trap 12 with the newly supplied water.

The water sprinkled from the second wash water supply means 60 and dropleted water is efficient at least one of the ammonia generated inside the bowl portion 11 and the ammonia existing around the bowl portion 11. Dissolves. As a result, when the second washing water supply means 60 sprinkles the dropletized water from the sprinkler portion 61 to the bowl portion 11 of the urinal body 10, the odor of ammonia generated from the urinal device 1 is further increased. It can be suppressed.

The functional water sprinkled from the second washing water supply means 60 dissolves and decomposes at least one of the ammonia generated inside the bowl portion 11 and the ammonia existing around the bowl portion 11. As a result, when the second washing water supply means 60 sprinkles the functional water, for example, even if the water in which ammonia is dissolved adheres around the urinal body 10 and evaporates, the odor due to ammonia is generated again. Can be suppressed.

<Control flow in cleaning operation of urinal device>
Next, with reference to FIGS. 3 and 4, the control flow in the cleaning operation of the urinal device of the present embodiment will be described. FIG. 3 is a flowchart for explaining a control flow in the cleaning operation of the urinal device of the present embodiment. FIG. 4 is a flowchart for explaining a control flow in determining periodic cleaning of the urinal device of the present embodiment. The control means 70 always repeats the control flow shown in FIG. 3 when the power is on.

First, in step S1, the control means 70 determines whether or not the human body detecting means 20 detects the user in front of the urinal body 10 (step S1). When the human body detecting means 20 does not detect the user in front of the urinal body 10, the control means 70 determines whether or not two hours or more have passed since the timer 72 started (step S2). That is, in step S2, the control means 70 determines whether or not the elapsed time from the previous use of the urinal device 1 or the previous periodic cleaning exceeds 2 hours (first predetermined time). ..
If two hours or more have passed since the timer 72 started in step S2, the control means 70 makes a periodic cleaning determination (step S3). If two hours or more have not passed since the timer 72 started in step S2, the process returns to step S1 again. The periodic cleaning judgment will be described in detail later.

When the human body detecting means 20 detects the user in front of the urinal body 10 in step S1, the control means 70 resets the timer 72 (step S4). After that, the control means 70 determines whether or not the user detected in step S1 has left the front of the urinal body 10, that is, whether or not the user has finished urinating (step S5). The control means 70 repeats this determination until the user moves away from the front of the urinal body 10, that is, until the user finishes urinating.

When the user leaves the front of the urinal body 10 in step S5, the control means 70 supplies water from the spreader 51 of the first washing water supply means 50 to the bowl portion 11 of the urinal body 10, so-called ". This cleaning is performed (step S6).

Next, in the urinal device 1, after performing the "main cleaning" in step S6, either the water supplied from the water supply source 5 or the hypochlorite water as the functional water capable of decomposing ammonia is used. Is "sprinkled and washed" by supplying the water from the sprinkler 61 to the bowl 11.

After performing step S6, the control means 70 determines whether or not the number of times the urinal device 1 has been used within the last hour is less than 10 times, based on the information stored in the storage unit 71 (step). S7).
If the number of times the urinal device 1 has been used in the last hour is less than 10 times in step S7, then the control means 70 further uses the urinal device 1 less than 5 times in the last hour. Whether or not it is determined (step S8). When the urinal device 1 has been used less than 5 times in the last hour in step S8, the control means 70 energizes the anode plate 42 and the cathode plate 43 as electrodes so that a current value of 1.0 A flows. Then, the functional water (hypochlorous acid water) generated by the functional water generating means 40 is supplied from the sprinkling portion 61 of the second washing water supply means 60 to the bowl portion 11 of the urinal body 10 (step S9). ). On the other hand, when the urinal device 1 has been used 5 times or more in the last hour in step S8, the control means 70 has a current value of 0.5 A flowing through the anode plate 42 and the cathode plate 43 as electrodes. After being energized in this way, the functional water (hypochlorous acid water) generated by the functional water generating means 40 is supplied from the sprinkling portion 61 of the second washing water supply means 60 to the bowl portion 11 of the urinal body 10. (Step S10).
Further, when the urinal device 1 has been used 10 times or more in the last hour in step S7, the control means 70 uses the so-called fresh water supplied from the water supply source 5 as the second wash water supply means 60. It is supplied from the sprinkler portion 61 to the bowl portion 11 of the urinal body 10 (step S11).

After supplying the functional water or fresh water to the bowl portion 11 of the urinal body 10 in steps S9 to S11, the control means 70 starts the timer 72 (step S12) to control the cleaning operation of the urinal device 1. To finish. Even after the periodic cleaning determination is made in step S3, the process proceeds to step S12, the timer 72 is started, and the control of the cleaning operation of the urinal device 1 is terminated.

In the control flow described above, when the urinal device 1 performs the cleaning operation (sprinkling cleaning), the urinal device 1 has been used less than 10 times in the last hour (the urinal device 1 is used first. If the frequency is less than the predetermined frequency), the functional water is sprinkled on the bowl portion 11, while the urinal device 1 has been used 10 times or more within the last hour (the urinal device 1 is used first). If the frequency is less than the predetermined frequency), so-called fresh water supplied from the water supply source 5 is sprinkled on the bowl portion 11.
Further, in the urinal device 1, when the cleaning operation (sprinkling cleaning) is performed with functional water (hypochlorous acid water), the number of times the urinal device 1 is used (frequency of use of the urinal device 1) within the last hour If it is less than 5 times, the urinal device 1 is used the number of times (urinal) in the last 1 hour while energizing the anode plate 42 and the cathode plate 43 as electrodes so that a current value of 1.0 A flows. When the frequency of use of the device 1) is 5 times or more, energization is performed so that a current value of 0.5 A flows through the anode plate 42 and the cathode plate 43 as electrodes.

Next, with reference to FIG. 4, the periodic cleaning determination in step S3 of FIG. 3 will be described. The urinal device 1 in the present embodiment is a urinal within the most recent day when the elapsed time after the previous use of the urinal device 1 exceeds a predetermined predetermined time (2 hours in the present embodiment). When the number of times the device 1 is used (the frequency of use of the urinal device 1) is less than 80 times, periodic cleaning is performed in which the functional water (hypochlorous acid water) is supplied from the sprinkler portion 61 to the bowl portion 11.

When the periodic cleaning determination is started, the control means 70 first resets the timer 72 (step S101). After that, the control means 70 determines whether or not the urinal device 1 has been used less than 80 times in the last day based on the information stored in the storage unit 71 (step S102).

If the number of times the urinal device 1 has been used in the last day is less than 80 times in step S102, then the control means 70 determines whether the number of times the urinal device 1 has been used less than 50 times in the last day. Is determined (step S103). When the urinal device 1 has been used less than 50 times in the last day in step S103, the control means 70 energizes the anode plate 42 and the cathode plate 43 as electrodes so that a current value of 1.0 A flows. Then, periodic cleaning is performed in which the functional water (hypochlorous acid water) generated by the functional water generating means 40 is supplied from the sprinkling portion 61 of the second washing water supply means 60 to the bowl portion 11 of the urinal body 10. (Step S104). On the other hand, when the urinal device 1 has been used 50 times or more in the last day in step S103, the control means 70 causes the anode plate 42 and the cathode plate 43 as electrodes to have a current value of 0.5 A. The functional water (hypochlorous acid water) generated by the functional water generating means 40 is supplied from the sprinkling portion 61 of the second washing water supply means 60 to the bowl portion 11 of the urinal body 10 on a regular basis. Washing is performed (step S105).
If the urinal device 1 has been used 80 times or more in the last day in step S102, the periodic cleaning determination is completed without performing the periodic cleaning.

In steps S104 and S105, after supplying the functional water (hypochlorous acid water) to the bowl portion 11 of the urinal body 10, the control means 70 ends the periodic cleaning determination.

In the control flow described above, when the elapsed time after the previous use exceeds a predetermined time (2 hours), the urinal device 1 has been used the number of times the urinal device 1 has been used (urinal device 1) within the most recent day. If the frequency of use of the device 1) is less than 80 times, periodic cleaning is performed to supply functional water to the bowl portion 11.
Further, when the urinal device 1 is regularly washed with functional water (hypochlorous acid water), the number of times the urinal device 1 is used (frequency of use of the urinal device 1) within the last day is less than 50 times. In this case, while energizing the anode plate 42 and the cathode plate 43 as electrodes so that a current value of 1.0 A flows, the number of times the urinal device 1 is used within the last day (frequency of use of the urinal device 1). When the number of times is 50 or more, energization is performed so that a current value of 0.5 A flows through the anode plate 42 and the cathode plate 43 as electrodes.

In the above embodiment, the periodic cleaning determination is made when the elapsed time after the previous use exceeds a predetermined predetermined time (2 hours), but the present invention is not limited to this.

The control flow in the cleaning operation of the urinal device of another embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a flowchart for explaining a control flow in the cleaning operation of the urinal device of another embodiment. FIG. 6 is a flowchart of the setting of the frequency of periodic cleaning of the urinal device of another embodiment. The steps similar to those of the present embodiment will be omitted, and only the different parts will be described.

First, in step S'1, the control means 70 determines whether or not the human body detecting means 20 detects the user in front of the urinal body 10 (step S'1). When the human body detecting means 20 does not detect the user in front of the urinal body 10 in step S'1, the control means 70 determines whether or not it is time to perform periodic cleaning (step S'2). .. This "whether or not it is time to perform regular cleaning" is determined based on the frequency of regular cleaning set at a predetermined time. In this embodiment, the time of day is 0 o'clock, which is a predetermined time when the frequency of regular cleaning is set.

Here, the setting of the frequency of periodic cleaning in another embodiment will be described once with reference to FIG. The control means 70 starts setting the frequency of periodic cleaning when the time reaches 0 o'clock, and first, based on the information stored in the storage unit 71, the urinal device 1 has been used less than 80 times in the last day. Whether or not it is determined (step S'101).
In step S'101, when the number of times the urinal device 1 has been used in the last day is less than 80 times, the control means 70 sets the frequency of performing the regular cleaning to 1.5 hours in the day. It is set to be performed at a single pace (step S'102). On the other hand, when the number of times the urinal device 1 has been used 80 times or more in the last day in step S'101, the control means 70 sets the frequency of performing the regular cleaning for 2 hours in the day. It is set to be performed once every time (step S'103).
In this way, once a day, the frequency of periodic cleaning is set according to the frequency of use of the urinal device 1.

As a result, for example, when the frequency of periodic cleaning is set so that the periodic cleaning is performed once every two hours in a day, the time of the periodic cleaning is 0:00, 2:00, and so on. It is held once every two hours, such as 4 o'clock, 6 o'clock, and so on. If the urinal device 1 is used at this time, periodic cleaning is performed when the urinal device 1 is not in use after the use is completed.

Here, the process returns to FIG. Based on the setting of the frequency of periodic cleaning shown in FIG. 6, it is determined in step S'2 whether or not it is the timing to perform periodic cleaning, and when it is the timing to perform periodic cleaning, the control means 70 serves as an electrode. Periodic cleaning is performed in which the electrode plate 42 and the cathode plate 43 are energized and the functional water (hypochlorous acid water) generated by the functional water generating means 40 is supplied from the sprinkler portion 61 to the bowl portion 11 (step S'3). ). If it is not the timing to perform the periodic cleaning in step S'2, the process returns to step S'1 again.

As shown in FIGS. 5 and 6, the number of times the urinal device 1 is used within the last day (frequency of use of the urinal device 1) when the time is 0 o'clock in the day (predetermined time). Set the frequency of regular cleaning according to. Specifically, when the number of times the urinal device 1 is used within the last day (frequency of use of the urinal device 1) is high, the frequency of regular cleaning is set to be low, while the frequency of regular cleaning is low. When the number of times the toilet bowl device 1 is used (frequency of use of the urinal device 1) is small, the frequency of periodic cleaning is set to be high. As a result, the frequency of periodic cleaning can be appropriately set according to the frequency of use of the urinal device 1, and the hygiene of the urinal can be efficiently maintained.

Further, in the present embodiment, when the elapsed time after the previous use exceeds a predetermined predetermined time (2 hours), whether or not to perform regular cleaning with functional water according to the frequency of use of the urinal device 1. However, the present invention is not limited to this, and when the elapsed time after the previous use exceeds a predetermined predetermined time (2 hours), the urinal device 1 is always used regardless of the frequency of use. Periodic cleaning with functional water may be performed.

Further, in the present embodiment, the main washing is performed with fresh water supplied from the water supply source 5 immediately after the user finishes urinating, and the watering washing performed after the main washing depends on the frequency of use of the urinal device 1. The present invention is not limited to this, and the present invention is not limited to this, and in the main cleaning performed immediately after the user finishes urinating, the functional water and the fresh water are used according to the frequency of use of the urinal device 1. You may use it properly.

Further, in the present embodiment, when performing the cleaning operation, functional water and fresh water are used properly according to the number of times the urinal device 1 has been used in the last hour, but the present invention is not limited to this, for example, cleaning. At the time of operation, functional water and fresh water may be used properly according to the time elapsed since the last use of the urinal device 1.

Further, in the present embodiment, the functional water produced by the functional water generating means 40 is hypochlorous acid water, but the present invention is not limited to this, and the function produced by the functional water generating means 40 is not limited to this.
