Japanese Unexamined Patent Publication No. 10-21608

After the cleaning in the bathroom is completed, the bathtub and the washing floor are in a wet state due to the water discharged for cleaning, and there is residual water for cleaning. Generally, if the water discharged for cleaning remains as residual water without evaporating, black mold is likely to occur in the vicinity of the portion where the residual water exists. Therefore, in order to suppress the generation of black mold, it is desirable that the residual water easily evaporates. However, after the cleaning in the bathroom is completed, the humidity in the bathroom is high due to the water discharged for cleaning, so that the evaporation of the residual water may be slow. Therefore, there is a risk that black mold will occur.

Further, when ventilation is performed after the watering by the watering means is completed as in the cleaning system described in Patent Document 1, it takes a long time until the humidity in the bathroom is lowered by the ventilation and the residual water is easily evaporated. May be required. As a result, the generation of black mold may not be effectively suppressed.

The present invention has been made based on the recognition of such a problem, and an object of the present invention is to provide a bathroom system capable of suppressing the generation of black mold in a bathroom.

The first invention is a cleaning device that cleans at least a part of a bathroom floor, a wall, and a bathtub by discharging washing water, a ventilation device provided in the bathroom to ventilate the bathroom, and the cleaning device. The control unit includes a control unit that interlocks and controls the ventilation device and the ventilation device, and the control unit is said to be running a cleaning mode in which at least a part of the washing place floor, the wall, and the bathtub is washed by the cleaning device. It is a bathroom system characterized in that a ventilation mode for ventilating the bathroom is executed by a ventilation device.

According to this bathroom system, the ventilation mode is executed while the cleaning mode is being executed, so that the increase in humidity in the bathroom can be suppressed from the time when the cleaning equipment is discharging water from the washing floor or the bathtub. It is possible to easily evaporate the residual water of the discharged washing water. As a result, the generation of black mold in the bathroom can be effectively suppressed.

A second aspect of the present invention, in the first invention, the ventilation mode includes a first mode in which ventilation is performed with a first air volume and a second mode in which ventilation is performed with a second air volume larger than the first air volume. However, the control unit is a bathroom system characterized in that the second mode is executed during the execution of the cleaning mode.

According to this bathroom system, it is possible to further suppress an increase in humidity in the bathroom by executing the second mode in which the air volume is large while the cleaning mode is being executed. This makes it possible to further suppress the generation of black mold in the bathroom.

A third aspect of the invention is the bathroom system according to the first or second aspect, wherein the control unit stops the ventilation mode after a predetermined time has elapsed from the end of the cleaning mode.

According to this bathroom system, since the ventilation mode is continued until a predetermined time elapses after the end of the cleaning mode, it is possible to suppress an increase in humidity in the bathroom even after the end of the cleaning mode. This makes it easier to evaporate the residual water of the washing water discharged from the washing equipment.

A fourth aspect of the invention is the second invention, in the case where the control unit has executed either the first mode or the second mode before the execution of the cleaning mode, the control unit has executed the cleaning mode after the end of the cleaning mode. It is a bathroom system characterized by executing any one of the first mode and the second mode.

According to this bathroom system, after the cleaning mode ends, the control unit automatically executes the ventilation mode before the cleaning mode is started. As a result, even if the ventilation mode is switched during the cleaning mode, the user does not need to return to the original ventilation mode, which is convenient.

A fifth aspect of the present invention includes, in the first invention, the ventilation mode includes a first mode in which ventilation is performed with a first air volume and a second mode in which ventilation is performed with a second air volume larger than the first air volume. When the ventilation mode is stopped at the start of the cleaning mode, the control unit executes the second mode during the execution of the cleaning mode, and executes the first mode at the start of the cleaning mode. If so, the bathroom system is characterized in that the first mode is executed during the execution of the cleaning mode.

According to this bathroom system, efficient ventilation can be performed by controlling the air volume of ventilation during the cleaning mode based on the state of the ventilation mode at the start of the cleaning mode. For example, by executing the first mode while the cleaning mode is being executed, it is possible to suppress an increase in power consumption as compared with the case of executing the second mode. Further, by executing the first mode while the cleaning mode is being executed, it is possible to suppress the operating noise (fan operating noise) of the ventilation equipment as compared with the case of executing the second mode.

A sixth aspect of the invention is the bathroom system according to any one of the first to fifth aspects, wherein the control unit executes the ventilation mode at the same time as the start of the cleaning mode.

According to this bathroom system, since the ventilation in the bathroom is performed from the start of the washing mode, it is possible to further suppress the increase in the humidity in the bathroom. This makes it possible to further suppress the generation of black mold in the bathroom.

According to the aspect of the present invention, there is provided a bathroom system capable of suppressing the generation of black mold in the bathroom.

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 perspective view illustrating a bathroom having a bathroom system according to an embodiment.
FIG. 1 shows an example of a bathroom in which the bathroom system 100 (see FIG. 2) according to the embodiment is installed.
As shown in FIG. 1, the bathroom 500 has a first wall 541, a second wall 542, a third wall 543, and a fourth wall 544 in an arrangement generally corresponding to the four sides of a rectangular parallelepiped. The second wall 542 faces the first wall 541, and the fourth wall 544 faces the third wall 543. The first wall 541 and the second wall 542 are connected to the third wall 543 and the fourth wall 544, respectively.

For convenience of explanation, in the present specification, the direction from the second wall 542 (the wall on the back side in FIG. 1) to the first wall 541 (the wall on the front side in FIG. 1) is referred to as "forward", and the direction opposite to this. Is "backward". In addition, the direction perpendicular to the front-back direction and the up-down direction is the horizontal direction.

A bathtub 510 is provided on the side of the fourth wall 544, and a washroom floor 520 (bathroom washroom floor) is provided between the bathtub 510 and the third wall 543. That is, the bathtub 510 and the washing floor 520 both extend in the front-rear direction and are arranged side by side. The washing floor 520 is in contact with a part of the first wall 541 and a part of the second wall 542 in addition to the third wall 543.

The washroom floor 520 is provided with a drainage port 521. The drainage port 521 is provided near the center of the washroom floor 520 in the front-rear direction and at the end of the washroom floor 520 on the side of the bathtub 510 in the lateral direction. The washing floor 520 is provided with a gentle drainage gradient (inclination) toward the drainage port 521 (for example, about 1 to 5 °). The surface of the washing floor 520 is hydrophilically coated.

A counter 530 is provided on a part of the second wall 542 (on the rear side of the bathroom 500) in contact with the washing floor 520. A mirror, a water tap, a shower hose, and the like are appropriately provided on the second wall 542 of the bathroom 500.

FIG. 2 is a block diagram illustrating the bathroom system according to the embodiment.
As shown in FIG. 2, the bathroom system 100 includes a cleaning device 200, a ventilation device 300, a control unit 30, and an operation unit 35.

The cleaning device 200 is provided in the bathroom 500. The cleaning device 200 has, for example, a spout for discharging the washing water, a solenoid valve for opening and closing a flow path for guiding the washing water from a water supply source (water pipe or the like) to the spout. The cleaning device 200 discharges the cleaning water supplied from the water supply source to at least a part of the washing floor 520, the walls (first to fourth walls 541 to 544) and the bathtub 510 of the bathroom 500. Thereby, the cleaning device 200 cleans at least a part of the washing floor 520, the wall and the bathtub 510. In the example shown in FIG. 1, the cleaning device 200 is a cleaning device 200a (floor cleaning device) provided on the counter 530 and for cleaning the washing floor 520.

The ventilation device 300 is provided in the bathroom 500 and has a ventilation means (fan) for ventilating the bathroom. For example, the ventilation device 300 may further have a heater. The ventilation device 300 can, for example, ventilate, heat, and dry the bathroom.

The control unit 30 is an electric circuit having, for example, a microcomputer. The control unit 30 is connected to each of the cleaning device 200 and the ventilation device 300. The connection between the control unit 30 and the cleaning device 200 and the connection between the control unit 30 and the ventilation device 300 may be a wired connection or a wireless connection. Each of the cleaning device 200 and the ventilation device 300 operates based on the signal (command) transmitted from the control unit 30. In the example shown in FIG. 1, the control unit 30 is installed on the ceiling 545 of the bathroom 500. However, the arrangement of the control unit 30 is arbitrary. Further, the control unit 30 may be appropriately divided and arranged on a plurality of substrates or the like. For example, a part of the control unit 30 may be arranged in the cleaning device 200 or the ventilation device 300.

The control unit 30 performs interlocking control in which one operation of the cleaning device 200 and the ventilation device 300 is linked to the other operation. That is, the control unit 30 controls the operation of one of the cleaning device 200 and the ventilation device 300 based on the operating state of the other. The details of this interlocking control will be described later.

Further, the bathroom system 100 has an operation unit 35 (remote controller) for the user to operate the cleaning device 200 and the ventilation device 300. The operation unit 35 is provided inside the bathroom 500 or outside the bathroom 500 (for example, a dressing room adjacent to the bathroom 500). The operation unit 35 is connected to the control unit 30 by wire or wirelessly. By operating a button (switch) provided on the operation unit 35, the user can start / stop the operation of the cleaning device 200 and the ventilation device 300, and change the operation setting. Specifically, when the user operates the operation unit 35, a signal corresponding to the operation is transmitted to the control unit 30. The control unit 30 transmits a signal (command) to each of the cleaning device 200 and the ventilation device 300 based on the signal from the operation unit 35.

An example of the cleaning device 200 (cleaning device 200a) will be described with reference to FIG.
FIG. 3 is a schematic diagram illustrating the cleaning equipment of the bathroom system according to the embodiment.
FIG. 3 shows a side view of the vicinity of the counter 530 of the bathroom 500.
The cleaning device 200a has a nozzle portion 10a protruding below the counter 530. The nozzle portion 10a is arranged at a position separated from the washing place floor 520 at the lower part of the counter 530. For example, the nozzle portion 10a is installed near the center of the washing floor 520 in the lateral direction.

A water supply pipe 51 is provided outside the bathroom 500 (for example, behind the second wall 542). The water supply pipe 51 is connected to a water pipe (not shown). As a result, tap water is supplied to the cleaning device 200a from the water supply pipe 51.

Inside the counter 530 (between the top plate 531 and the lower cover 532), the first strainer 53a, the first solenoid valve 54a, the second solenoid valve 54b, the pressure regulating valve 55, and the vacuum breaker 57 are reversed. A check valve 56, a functional water generation unit 20, a second strainer 53b, and an electric motor 17 are provided. The first strainer 53a is connected to the water supply pipe 51, and the tap water flow path is branched into two in the downstream of the first strainer 53a.

One flow path on the downstream side of the first strainer 53a directly supplies tap water (an example of washing water) to the nozzle portion 10a via the first solenoid valve 54a. By opening the first solenoid valve 54a, tap water is supplied to the nozzle portion 10a.

In the other flow path on the downstream side of the first strainer 53a, a second electromagnetic valve 54b, a pressure regulating valve 55, a vacuum breaker 57, a check valve 56, a functional water generator 20, and a second strainer 53b are arranged in this order from the upstream side. It is connected and supplies functional water (an example of washing water) to the nozzle portion 10a.

The first solenoid valve 54a and the second solenoid valve 54b perform an operation of opening the flow path of tap water and an operation of closing the flow path of tap water, respectively. The pressure regulating valve 55 controls the pressure of the supplied tap water. As a result, the flow rate of tap water supplied to the functional water generation unit 20, which will be described later, can be adjusted as desired. By adjusting the flow rate of tap water supplied to the functional water generation unit 20, the flow rate of the functional water supplied to the nozzle unit 10a is adjusted. The flow rate of tap water may be adjusted by using the second solenoid valve 54b.

The functional water is, for example, sterilized water having a sterilizing (or sterilizing) function. Fuctional water contains, for example, hypochlorous acid. In this example, the functional water generation unit 20 is an electrolytic cell (electrolytic cell) having an anode and a cathode. The functional water generation unit 20 applies a voltage between the anode and the cathode to electrolyze the tap water flowing between the electrodes to generate low-concentration hypochlorous acid. Since tap water contains chloride ions, hypochlorous acid is produced by electrolyzing the chloride ions.

The functional water is not limited to those containing hypochlorous acid. For example, the functional water may be a solution containing metal ions such as silver ion copper ion or zinc ion, a solution containing electrolytic chlorine or ozone, acidic water, alkaline water or the like. The functional water generation unit 20 is not limited to the electrolytic cell, and may have any configuration capable of generating sterilized water.

At least a part of the strainers 53a and 53b, the solenoid valves 54a and 54b, the pressure regulating valve 55, the vacuum breaker 57, the check valve 56, the functional water generator 20 and the electric motor 17 is provided outside the counter 530 or outside the bathroom 500. It is also possible to be.

The first solenoid valve 54a, the second solenoid valve 54b, the pressure regulating valve 55, and the functional water generation unit 20 are appropriately controlled by the control unit 30. Thereby, the sprinkling of tap water from the nozzle portion 10a and the sprinkling of the functional water from the nozzle portion 10a can be controlled independently of each other.

Specifically, the first solenoid valve 54a and the second solenoid valve 54b open and close the flow path of tap water based on the signal from the control unit 30. As a result, the flow rate of tap water supplied to the downstream side is controlled. Further, the functional water generation unit 20 switches ON / OFF of the electrolytic chamber based on the signal from the control unit 30. In this way, the control unit 30 can control the concentration of various components in the functional water, the flow rate of the washed water discharged (flow rate per unit time), and the total amount of the washed water discharged.

Further, the nozzle portion 10a is provided with a water discharge port 12 (opening). The nozzle portion 10a discharges the washing water (tap water or functional water) supplied from the upstream from the water discharge port 12 onto the washing place floor 520 of the bathroom 500 by water pressure. As a result, dirt on the washing floor 520 (for example, sebum, dirt, hair, etc. from the human body) can be washed away to the drain port 521, and the bacteria on the washing floor 520 can be sterilized. The washing water discharged from the nozzle portion 10a is, for example, in the form of a mist.

The position and orientation of the nozzle portion 10a can be varied so as to change the area on the washing floor 520 where the washing water is discharged. Specifically, the nozzle portion 10a is rotationally driven by the electric motor 17. The electric motor 17 includes, for example, a stepping motor.

The electric motor 17 is controlled by the control unit 30. By controlling the electric motor 17 based on the signal from the control unit 30, the rotation angle and rotation speed of the nozzle unit 10a change.

An example of the ventilation device 300 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a schematic diagram illustrating a configuration of a main part of a ventilation device of a bathroom system according to an embodiment. In FIG. 4, the air passage system and the electric system are shown together.
FIG. 5 is a cross-sectional view illustrating the ventilation equipment of the bathroom system according to the embodiment.

As shown in FIG. 4, the ventilation device 300 has an air passage 316, a heating means 318 (heating unit, a heater), and a fan 322. The air passage 316 has a suction port 312 and an outlet 314.

In this example, the ventilation device 300 is a built-in (ceiling embedded) type. That is, as shown in FIG. 5, in the state of being installed on the ceiling 545, the upper portion of the ventilation device 300 is located above the ceiling 545 and is arranged outside the bathroom 500. The lower part of the ventilation device 300 is located below the ceiling 545 and is located inside the bathroom 500.

The air passage 316 shown in FIG. 4 is an air passage provided inside the housing 311 of the ventilation device 300. The air passage 316 connects the suction port 312 and the air outlet 314. The suction port 312 and the air outlet 314 each lead to the bathroom 500. As a result, the air passage 316 communicates with the inside of the bathroom 500 via the suction port 312 and the air outlet 314.

The fan 322 is provided inside the air passage 316. The fan 322 includes, for example, a motor. When the fan 322 (motor) is energized, the motor rotates and the fan 322 is driven. As a result, the fan 322 generates an air flow in the air passage 316.

As shown by the arrows A1 shown in FIGS. 4 and 5, the suction port 312 sucks the air in the bathroom according to the operation of the fan 322. The sucked air passes through the air passage 316 and is guided to the outlet 314 by the fan 322. As shown by the arrows A2 shown in FIGS. 4 and 5, the air outlet 314 blows the air sucked by the suction port 312 into the bathroom 500.

The heating means 318 is provided inside the air passage 316. In the example of FIG. 2, the heating means 318 is located between the fan 322 and the outlet 314 on the air passage 316. The heating means 318 is, for example, an electric heater and has a heating element that generates heat when energized. The heating means 318 may have any configuration capable of generating heat to warm the air.

When the heating means 318 is energized, the heating means 318 heats the air in the air passage 316. That is, the heating means 318 heats the air sucked by the suction port 312. As a result, the heated air can be blown out from the outlet 314.

Further, as shown in FIG. 5, the ventilation device 300 further has a suction port 332 and a discharge port 334. As a result, as shown by arrow A3, outside air (for example, air in a dressing room provided adjacent to the bathroom 500) is sucked in from the suction port 332. Further, by adjusting the position of the damper 336, the sucked air is discharged to the outside of the bathroom from the discharge port 334 as shown by the arrow A4.

The control unit 30 is connected to a fan 322, a heating means 318, and a damper 336. The control unit 30 controls the operation of the fan 322 (energization), the operation of the heating means 318 (energization), and the operation of the damper 336. As a result, the ventilation device 300 performs "ventilation operation" to ventilate the air inside the bathroom 500, "heating operation" to warm the air inside the bathroom 500, and sends warm air to the inside of the bathroom 500 to send warm air to the bathroom 500 and the bathroom. A "drying operation" can be performed to dry the clothes in 500.

In the ventilation operation, the control unit 30 closes the outlet 314 by the damper 336 and opens the outlet 334. In this state, the control unit 30 operates the fan 322. At this time, the heating means 318 is not operated (the heater is not energized). The air sucked from the bathroom 500 by the fan 322 is discharged to the outside or the like from the discharge port 334. As a result, the air in the bathroom 500 can be replaced (ventilated).

In the heating operation, the control unit 30 closes the discharge port 334 by the damper 336 and opens the outlet 314. In this state, the control unit 30 operates the fan 322 and operates the heating means 318 (energizes the heater). The air sucked from the bathroom 500 by the fan 322 is heated by the heating means 318 and then blown out from the outlet 314 into the bathroom 500. As a result, the air in the bathroom 500 is heated by the heating means 318 while circulating, so that the temperature in the bathroom 500 rises.

In the dry operation, the control unit 30 opens both the outlet 314 and the outlet 334 by the damper 336. In this state, the control unit 30 operates the fan 322 and operates the heating means 318. A part of the air sucked from the inside of the bathroom 500 by the fan 322 is discharged to the outside or the like from the discharge port 334. The remaining part of the sucked air is heated by the heating means 318 and then blown out from the outlet 314 into the bathroom 500 and circulates in the bathroom 500.

In the embodiment, the ventilation device 300 may not have the heating means 318 (heater), and may not perform the heating operation and the drying operation. The ventilation device 300 may have a ventilation means having an arbitrary configuration capable of replacing the air in the bathroom 500.

FIG. 6 is a perspective view illustrating an operation unit of the bathroom system according to the embodiment.
The operation unit 35 (remote controller) has a plurality of switches (buttons) such as a first ventilation switch 35a, a second ventilation switch 35b, a cleaning interlocking switch 35c, a bathtub cleaning switch 35d, and a floor cleaning switch 35e.

The control unit 30 has a ventilation mode for ventilating the bathroom 500 by the ventilation device 300. When the user operates either the first ventilation switch 35a or the second ventilation switch 35b, the control unit 30 receives a signal corresponding to the operation and executes the ventilation mode. In the ventilation mode, the control unit 30 activates the ventilation means (fan 322) of the ventilation device 300 to cause the ventilation device 300 to perform the above-mentioned ventilation operation.

Further, the ventilation mode has a first mode in which ventilation is performed with a first air volume and a second mode in which ventilation is performed with a second air volume. The second air volume is larger than the first air volume. For example, the first mode is an operation mode in which the ventilation device 300 is made to perform weak ventilation (or 24-hour ventilation), and the second mode is an operation mode in which the ventilation device 300 is made to perform strong ventilation.

When the user operates the first ventilation switch 35a (24-hour ventilation switch), the control unit 30 receives a signal corresponding to the operation and executes the first mode. In the first mode, the control unit 30 operates the fan 322 with the first electric power to cause the ventilation device 300 to perform the ventilation operation. Similarly, when the user operates the second ventilation switch 35b (strong ventilation switch), the control unit 30 receives a signal corresponding to the operation and executes the second mode. In the second mode, the control unit 30 operates the fan 322 with the second electric power to cause the ventilation device 300 to perform the ventilation operation.

The second power (watt) of the fan 322 in the second mode is larger than the first power (watt) of the fan 322 in the first mode. Therefore, in the second mode, the rotation speed of the motor of the fan 322 is higher than that in the first mode. As a result, the second air volume in the second mode is larger than the first air volume in the first mode.

Further, the control unit 30 has a washing mode in which at least a part of the washing place floor 520, the walls (first to fourth walls 541 to 544) and the bathtub 510 is washed by the washing device 200. When the user operates any of the cleaning interlocking switch 35c, the bathtub cleaning switch 35d, and the floor cleaning switch 35e, the control unit 30 receives a signal corresponding to the operation and executes the cleaning mode. In the cleaning mode, the control unit 30 controls the cleaning device 200 to cause the cleaning device 200 to perform a cleaning operation (water discharge operation to the bathroom) of the bathroom.

The cleaning mode includes, for example, a floor cleaning mode, a bathtub cleaning mode, and a cleaning interlocking mode. For example, when the user operates the floor cleaning switch 35e, the control unit 30 executes the floor cleaning mode. As a result, a signal is sent from the control unit 30 to the cleaning device 200a (floor cleaning device), and cleaning of the washing place floor 520 is started. Further, when the user operates the bathtub cleaning switch 35d, the control unit 30 executes the bathtub cleaning mode. As a result, a signal is sent from the control unit 30 to the cleaning device 200b (bathtub cleaning device) described later, and cleaning of the bathtub 510 is started. Further, when the user operates the cleaning interlocking switch 35c, the cleaning interlocking mode is executed. As a result, a signal is sent from the control unit 30 to the cleaning device 200a and the cleaning device 200b, and the cleaning operation of the cleaning device 200a (floor cleaning device) and the cleaning operation of the cleaning device 200b (bathtub cleaning device) are interlocked with each other. But at the same time. As a result, the time required for cleaning the bathroom 500 can be shortened, and the time and effort for the user to operate the operation unit 35 can be saved. In the embodiment, the number of cleaning devices may be one.

Next, interlocking control between the cleaning device 200 and the ventilation device 300 by the control unit 30 will be described.
In this interlocking control, the control unit 30 executes the ventilation mode while the cleaning mode is being executed. This example will be described below with reference to the figures.

7 (a) to 7 (c) are timing charts illustrating the operation of the bathroom system according to the embodiment.
In the timing chart, the horizontal axis is time (t). FIG. 7A shows the timing at which the user operates the cleaning switch (cleaning interlocking switch 35c, bathtub cleaning switch 35d, floor cleaning switch 35e) of the operation unit 35. FIG. 7B shows the timing of execution (ON) and stop (OFF) of the cleaning mode. FIG. 7C shows the timing of execution (ON) and stop (OFF) of the ventilation mode.

When the cleaning mode is ON, at least one of the floor cleaning mode, the bathtub cleaning mode, and the cleaning interlocking mode is executed. When the cleaning mode is OFF, none of the floor cleaning mode, the bathtub cleaning mode, and the cleaning interlocking mode is executed. That is, when the cleaning mode is OFF, the bathroom 500 is not washed (water is discharged into the bathroom 500). Further, when the ventilation mode is ON, either the first mode or the second mode is executed. When the ventilation mode is OFF, neither the first mode nor the second mode is executed. That is, when the ventilation mode is OFF, the bathroom 500 is not ventilated.

As shown in FIG. 7A, at time T1, the user operates the cleaning switch of the operation unit 35. Then, as shown in FIG. 7B, at time T1, the control unit 30 starts the cleaning mode. The wash mode ends at time T3 after time T1. That is, the cleaning operation of the cleaning device 200 is executed between the time T1 and the time T3, and the cleaning water is discharged from the cleaning device 200 into the bathroom 500. Then, as shown in FIG. 7 (c), the control unit 30 executes the ventilation mode during the execution of the cleaning mode, that is, between the time T1 and the time T3. In this example, the ventilation mode starts at time T2 after time T1 and ends at time T3.

Thus, in the embodiment, the ventilation mode is executed during the execution of the wash mode. That is, the ventilation operation of the ventilation device 300 is executed while the washing device 200 is discharging water to the washing place floor 520 and the bathtub 510. As a result, it is possible to suppress an increase in humidity in the bathroom 500 from the time when the cleaning device 200 is discharging water. Therefore, it is possible to easily evaporate the residual water of the washing water discharged from the washing device 200. As a result, the generation of black mold in the bathroom 500 can be effectively suppressed.

The ventilation mode may be started at the same time as the start of the washing mode (time T1). As a result, ventilation in the bathroom 500 is performed from the start of the cleaning mode, so that an increase in humidity in the bathroom can be further suppressed. Further, the end of the ventilation mode may be before the end of the washing mode (time T3) or after the end of the washing mode.

8 (a) to 8 (d) are timing charts illustrating the operation of the bathroom system according to the embodiment.
FIG. 8A shows the timing at which the user operates the cleaning switch of the operation unit 35. FIG. 8B shows the timing of execution (ON) and stop (OFF) of the cleaning mode. FIG. 8C shows the timing of execution (ON) and stop (OFF) of the first mode. FIG. 8D shows the timing of execution (ON) and stop (OFF) of the second mode.

As shown in FIG. 8A, at time T4, the user operates the cleaning switch of the operation unit 35. Then, as shown in FIG. 8B, at time T4, the control unit 30 starts the cleaning mode. The wash mode ends at time T6 after time T4. That is, the cleaning operation of the cleaning device 200 is executed between the time T4 and the time T6, and the cleaning water is discharged from the cleaning device 200 into the bathroom 500.

In this example, as shown in FIGS. 8 (c) and 8 (d), the first mode (weak ventilation) is executed before the start of the washing mode (time T4), and the second mode (the second mode (time T4) is executed. Strong ventilation) has not been performed. Then, the control unit 30 executes the second mode during the execution of the cleaning mode, that is, between the time T4 and the time T6. In this example, the ventilation mode is switched from the first mode to the second mode at the time T5 after the time T4 and ends at the time T6. It ends at time T6.

FIG. 9 is a graph illustrating the humidity in the bathroom.
FIG. 9 shows an example of the humidity in the bathroom when the washing mode starts at time T4 and ends at time T6, as shown in FIGS. 8A and 8B.
Humidity H1 indicates the change in humidity in the bathroom when the ventilation mode is switched from the first mode to the second mode at time T5, as described with respect to FIGS. 8 (c) and 8 (d). ..
Humidity H2 indicates a change in humidity in the bathroom when the ventilation mode is not switched at time T5 and the first mode is continued from time T4 to time T6.
Humidity H3 indicates the change in the humidity of the bathroom when the ventilation mode is stopped at time T5. That is, in the humidity H3, the first mode is executed from the time T4 to the time T5, and ventilation is not performed after the time T5.

As shown in FIG. 9, after the time T5 when the cleaning mode is being executed, the humidity H1 is lower than the humidity H2 and lower than the humidity H3. As described above, by executing the second mode in which the air volume is large during the execution of the cleaning mode, it is possible to further suppress the increase in humidity in the bathroom 500 and make it easier to evaporate the residual water of the cleaning water. can. Thereby, the generation of black mold in the bathroom 500 can be further suppressed.

In the example of FIG. 8, the switching from the first mode to the second mode may be performed at the same time as the start of the cleaning mode (time T4). As a result, since ventilation is performed in the second mode with a large air volume from the start of the cleaning mode, it is possible to further suppress an increase in humidity in the bathroom.

10 (a) to 10 (c) are timing charts illustrating the operation of the bathroom system according to the embodiment.
FIG. 10A shows the timing at which the user operates the cleaning switch of the operation unit 35. FIG. 10B shows the timing of execution (ON) and stop (OFF) of the cleaning mode. FIG. 10C shows the timing of execution (ON) and stop (OFF) of the ventilation mode.

As shown in FIG. 10A, at time T7, the user operates the cleaning switch of the operation unit 35. Then, as shown in FIG. 10B, at time T7, the control unit 30 starts the cleaning mode. The wash mode ends at time T9 after time T7. Then, as shown in FIG. 10 (c), the control unit 30 executes the ventilation mode during the execution of the cleaning mode, that is, between the time T7 and the time T9.

In this example, the ventilation mode is started at time T8 after time T7. Further, the ventilation mode ends at a time T10 after the time T9 when the cleaning mode ends. That is, the control unit 30 stops the ventilation mode after a predetermined time P1 has elapsed from the end of the cleaning mode. As a result, since the ventilation mode is continued until a predetermined time elapses after the end of the cleaning mode, it is possible to suppress an increase in the humidity in the bathroom 500 even after the end of the cleaning mode. As a result, the residual water of the washing water discharged from the washing device 200 can be more easily evaporated, and the generation of black mold can be further suppressed.

The predetermined time P1 is arbitrary, but can be appropriately determined, for example, according to the speed at which the humidity in the bathroom 500 drops depending on the ventilation mode and the speed at which the washing water discharged into the bathroom 500 is drained. .. The predetermined time P1 is, for example, about 10 to 20 minutes.

FIG. 11 is a flowchart illustrating the operation of the bathroom system according to the embodiment.
When the user presses the cleaning switch of the operation unit 35, the control unit 30 executes the cleaning mode (step S101). As a result, the cleaning device 200 starts cleaning the inside of the bathroom 500.

If the ventilation mode is executed when the cleaning switch is pressed (when the cleaning mode is started), the control unit 30 stores the ventilation mode (step S102). More specifically, the control unit 30 determines whether or not the ventilation mode was executed when the cleaning switch was pressed, and if the ventilation mode was executed, either the first mode or the second mode. Remember what was being done.
If the ventilation mode is not executed when the cleaning switch is pressed (when the cleaning mode is started), either the first mode or the second mode is executed during the cleaning mode. You may.

After that, the cleaning in the bathroom 500 is executed by the cleaning mode (step S103). During the execution of the cleaning mode, the control unit 30 continues the second ventilation mode when the ventilation mode stored in step S102 is the second mode (step S104: YES) (step S105). On the other hand, during the execution of the cleaning mode, if the ventilation mode stored in step 102 is not the second mode mode (step S104: NO), the control unit 30 shifts to the second mode (step S106).

When the first predetermined time elapses from the start of the cleaning mode (step S107: YES), the cleaning mode ends (step S108).

When the second predetermined time elapses after the cleaning mode ends (step S109: YES), the control unit 30 shifts to the ventilation mode stored in step S102 (step S110). That is, if the second mode was executed when the cleaning switch was pressed, the control unit 30 continues the second mode in step S110. If the first mode was executed when the cleaning switch was pressed, the control unit 30 shifts from the second mode to the first mode in step S110.

The second predetermined time in step S109 is appropriately and arbitrarily determined as in the predetermined time P1 described with respect to FIG. 10. Further, the second predetermined time may be zero, and the control unit 30 may shift to the stored ventilation mode at the same time as the end of the cleaning mode.

12 (a) to 12 (d) are timing charts illustrating the operation of the bathroom system according to the embodiment. These figures represent an example of the operation described with respect to FIG.
FIG. 12A shows the timing at which the user operates the cleaning switch of the operation unit 35. FIG. 12B shows the timing of execution (ON) and stop (OFF) of the cleaning mode. FIG. 12 (c) shows the timing of execution (ON) and stop (OFF) of the first mode. FIG. 12D shows the timing of execution (ON) and stop (OFF) of the second mode.

As shown in FIG. 12A, at time T11, the user operates the cleaning switch of the operation unit 35. Then, as shown in FIG. 12B, at time T11, the control unit 30 starts the cleaning mode. The wash mode ends at time T14 after time T11.

In this example, as shown in FIGS. 12 (c) and 12 (d), the first mode is executed before the start of the wash mode and at time T11. Therefore, the control unit 30 remembers that the first mode was executed as described with respect to step S102. Then, the control unit 30 executes the second mode while the cleaning mode is being executed. In this example, the ventilation mode is switched from the first mode to the second mode at time T13 after time T11.

After that, when the cleaning mode ends at time T14, the control unit 30 shifts to the stored ventilation mode as described with respect to step S110. That is, as shown in FIGS. 12 (c) and 12 (d), at time T14, the ventilation mode is switched from the second mode to the first mode.

As described above, in the example described with respect to FIGS. 11 and 12, if the control unit 30 has executed either the first mode or the second mode before the execution of the cleaning mode, the control unit 30 is cleaned after the end of the cleaning mode. Execute the mode that was executed before executing the mode.
That is, the ventilation mode before the cleaning mode is started is automatically executed by the control unit 30 after the cleaning mode ends. As a result, even when the ventilation mode is switched during the cleaning mode, the user does not need to return to the original ventilation mode, which is convenient.

FIG. 13 is a flowchart illustrating the operation of the bathroom system according to the embodiment.
Steps S201 to S203 are the same as steps S101 to S103 described with respect to FIG.

After that, during the execution of the cleaning mode, if the control unit 30 remembers that the ventilation mode is being executed in step S202 (step S204: YES), the control unit 30 maintains the execution of the ventilation mode (step S205). .. That is, when the cleaning mode is started, if the first mode is being executed, the execution of the first mode is maintained, and if the second mode is being executed, the execution of the second mode is executed. maintain. On the other hand, while the cleaning mode is being executed, the control unit 30 executes the second mode when it remembers that the ventilation mode is not executed in step S202 (step S204: No). That is, when neither the first mode nor the second mode is executed when the cleaning mode is started, the second mode is executed.

Subsequent steps S207 to S210 are the same as steps S107 to S110 described with respect to FIG.

As described above, when the ventilation mode is stopped at the start of the cleaning mode, the control unit 30 executes the second mode during the execution of the cleaning mode. That is, if ventilation is not performed at the start of the washing mode, it is considered that the humidity in the bathroom 500 is relatively high at the start of the washing mode, so that the second mode with a large air volume is executed.

On the other hand, if the control unit 30 has executed the first mode at the start of the cleaning mode, the control unit 30 executes the first mode during the execution of the cleaning mode. That is, if ventilation is performed in the first mode at the start of the washing mode, it is considered that the humidity in the bathroom 500 is relatively low at the start of the washing mode, so that the first mode with a small air volume is continued.

In this way, efficient ventilation can be performed by controlling the air volume of ventilation during the cleaning mode based on the state of the ventilation mode at the start of the cleaning mode. For example, by executing the first mode while the cleaning mode is being executed, it is possible to suppress an increase in power consumption as compared with the case of executing the second mode. Further, by executing the first mode while the cleaning mode is being executed, it is possible to suppress the operating noise (fan operating noise) of the ventilation device 300 as compared with the case of executing the second mode.

Another example of the cleaning device 200 (cleaning device 200b) will be described with reference to FIG. FIG. 14 is a schematic diagram illustrating the cleaning equipment of the bathroom system according to the embodiment.
The cleaning device 200b is a bathtub cleaning device that cleans the bathtub 510 by discharging cleaning water to the bathtub 510.
The cleaning device 200b includes a flow rate detecting device 604, a water amount control device 605, a solenoid valve 606, a cleaning nozzle 601, a water supply channel 608, a drain plug driving motor 624, and the like.

The cleaning nozzle 601 is connected to the water supply pipe 51 via the water supply channel 608. As a result, tap water that has passed through the water supply channel 608 is supplied from the water supply pipe 51 to the cleaning nozzle 601.

The water supply channel 608 is provided with a flow rate detecting device 604, a water amount control device 605, and a solenoid valve 606 in this order from the upstream side. The solenoid valve 606 performs an operation of opening the water supply passage 608 and an operation of closing the water supply passage 608. When the solenoid valve 606 opens, tap water is supplied to the cleaning nozzle 601 and when the solenoid valve 606 closes, the supply of water to the cleaning nozzle 601 is stopped.

The cleaning nozzle 601 is provided in the bathtub 510. The spout 601a of the cleaning nozzle 601 is exposed on the inner wall of the bathtub 510, for example. The cleaning nozzle 601 discharges the cleaning water (tap water) supplied from the upstream from the water discharge port 601a into the bathtub 510 by water pressure. As a result, the dirt in the bathtub 510 can be washed away to the drain port 512 of the bathtub 510. The washing water discharged from the washing nozzle 601 is, for example, in the form of a mist.

The drain plug drive motor 624 can operate the thrust lock mechanism portion 623 via the wire cable 621. By operating the thrust lock mechanism portion 623, the drain plug 622 can be moved up and down, and the drain port 512 can be opened and closed. The user can also operate the thrust lock mechanism portion 623 and open / close the drain port 512 by operating the manual switch 620 provided on the rim of the bathtub 510 or the like.

The flow rate detection device 604, the water amount control device 605, the solenoid valve 606, and the drain plug drive motor 624 are connected to the control unit 30 by wire or wirelessly, and are appropriately controlled by the control unit 30. That is, the solenoid valve 606 opens and closes the water supply channel 608 based on the signal from the control unit 30. As a result, the water discharge and the water stop of the cleaning nozzle 601 can be switched. Further, the drain plug drive motor 624 opens and closes the drain port 512 based on the signal from the control unit 30.

In the cleaning operation of the bathtub 510 by the cleaning device 200b, the control unit 30 first opens the drain port 512 by the drain plug driving motor 624. As a result, the water (hot water) remaining in the bathtub 510 is drained. A predetermined time has elapsed since the drain port 512 was opened, and after drainage is performed, the control unit 30 opens the solenoid valve 606. As a result, the washing water is discharged from the washing nozzle 601 into the bathtub 510, and the inside of the bathtub 510 can be washed.

The cleaning device 200b may discharge not only tap water but also functional water having the same configuration as the cleaning device 200a. Further, the cleaning device 200b may have a detergent tank or a pump inside, and the detergent may be sprayed from the cleaning nozzle 601 into the bathtub 510.
