Description

  Aspects of the invention generally relate to a bathroom system.

2. Description of the Related Art Conventionally, an apparatus for cleaning a bathroom by discharging water is known. For example, the cleaning system described in Patent Literature 1 includes a watering means for spraying water in a bathtub and a washing place, and a detergent spraying means for spraying detergent in the bathtub and the washing place.
Furthermore, the cleaning system of Patent Document 1 has ventilation means for ventilating the inside of the bathroom. Patent Document 1 describes that the inside of a bathroom after washing is dried by a ventilation means.

Japanese Patent Laid-Open No. 10-216068

  After washing in the bathroom, the bathtub and washing floor are wet due to the water discharged for washing, and there is residual washing water. In general, when the water discharged for cleaning does not evaporate and remains as residual water, black mold tends to occur near the portion where the residual water exists. Therefore, in order to suppress the occurrence of black mold, it is desirable that the residual water is easily evaporated. However, after completion of cleaning in the bathroom, the water in the bathroom is high due to the water discharged for cleaning, and thus evaporation of residual water may be slow. For this reason, black mold may be generated.

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

  This invention is made | formed based on recognition of this subject, and it aims at providing the bathroom system which can suppress generation | occurrence | production of the black mold in a bathroom.

  A first aspect of the present invention is a cleaning device that cleans at least a part of a bathroom floor, walls, and a bathtub by discharging water, a ventilation device that is provided in the bathroom and ventilates the bathroom, and the cleaning device. And a control unit that interlocks and controls the ventilation device, and the control unit is configured to execute the cleaning mode in which the cleaning device cleans at least a part of the wash floor, the wall, and the bathtub. In the bathroom system, a ventilation mode for ventilating the bathroom is executed by a ventilation device.

  According to this bathroom system, since the ventilation mode is executed during the execution of the cleaning mode, it is possible to suppress an increase in humidity in the bathroom from when the cleaning equipment is spitting water on the washing floor or the bathtub. It is possible to easily evaporate the residual water of the discharged wash water. Thereby, generation | occurrence | production of the black mold in a bathroom can be suppressed effectively.

  In a second aspect based on the first aspect, 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 larger than the first air volume. And the said control part is a bathroom system characterized by performing the said 2nd mode during execution of the said washing | cleaning mode.

  According to this bathroom system, an increase in humidity in the bathroom can be further suppressed by executing the second mode in which the air volume is large during the execution of the cleaning mode. Thereby, generation | occurrence | production of the black mold in a bathroom can be suppressed more.

  A third invention is the bathroom system according to the first or second invention, wherein the control unit stops the ventilation mode after a predetermined time has elapsed since the cleaning mode was completed.

  According to this bathroom system, since the ventilation mode is continued until a predetermined time has elapsed after the end of the cleaning mode, an increase in humidity in the bathroom can be suppressed even after the end of the cleaning mode. Thereby, the remaining water of the cleaning water discharged from the cleaning device can be more easily evaporated.

  In a fourth aspect based on the second aspect, the control unit performs the first mode or the second mode before the execution of the cleaning mode. One of the first mode and the second mode is executed.

  According to this bathroom system, the ventilation mode before the start of the cleaning mode is automatically executed by the control unit after the end of the cleaning mode. Thereby, 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.

  In a fifth aspect based on the first aspect, 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 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 it is, 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 during execution of the cleaning mode, it is possible to suppress an increase in power consumption compared to the case of executing the second mode. Further, by executing the first mode during the execution of the cleaning mode, it is possible to suppress the operation sound of the ventilator (the operation sound of the fan) compared to the case of executing the second mode.

  A sixth invention is the bathroom system according to any one of the first to fifth inventions, wherein the control unit executes the ventilation mode simultaneously with the start of the cleaning mode.

  According to this bathroom system, since ventilation in the bathroom is performed from the start of the cleaning mode, an increase in humidity in the bathroom can be further suppressed. Thereby, generation | occurrence | production of the black mold in a bathroom can be suppressed more.

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

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 a bathroom system 100 (see FIG. 2) according to the embodiment is installed.
As illustrated in FIG. 1, the bathroom 500 includes a first wall 541, a second wall 542, a third wall 543, and a fourth wall 544 that are arranged substantially corresponding to four side surfaces 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 this specification, the direction from the second wall 542 (the back wall in FIG. 1) to the first wall 541 (the near wall in FIG. 1) is defined as “front”, and the opposite direction. Is “backward”. Further, a direction perpendicular to the front-rear direction and the up-down direction is defined as a lateral direction.

  A bathtub 510 is provided on the fourth wall 544 side, and a washing floor 520 (bathroom washing floor) is provided between the bathtub 510 and the third wall 543. That is, the bathtub 510 and the washing ground floor 520 both extend in the front-rear direction and are arranged in the horizontal direction. 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 washing floor 520 is provided with a drain outlet 521. The drain outlet 521 is provided in the vicinity of the center in the front-rear direction of the washing floor 520 and at the end on the bathtub 510 side in the lateral direction of the washing floor 520. The washing floor 520 is provided with a gentle (for example, about 1 to 5 °) drainage gradient (inclination) toward the drain outlet 521. Further, the surface of the washing floor 520 is coated with a hydrophilic coating.

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

FIG. 2 is a block diagram illustrating a bathroom system according to the embodiment.
As illustrated 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 includes, for example, a water outlet that discharges cleaning water, and an electromagnetic valve that opens and closes a flow path that leads the cleaning water from a water supply source (such as a water pipe) to the water outlet. 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. Accordingly, the cleaning device 200 cleans at least a part of the washing floor 520, the wall, and the bathtub 510. In the example illustrated in FIG. 1, the cleaning device 200 is a cleaning device 200 a (floor cleaning device) that is provided in the counter 530 and cleans the washing floor 520.

  The ventilation device 300 is provided in the bathroom 500 and has ventilation means (fan) for ventilating the bathroom. For example, the ventilation device 300 may further include a heater. For example, the ventilation device 300 can perform ventilation, heating, and drying in a 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 wired connection or wireless connection. Each of the cleaning device 200 and the ventilation device 300 operates based on a 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. In addition, the control unit 30 may be appropriately divided and arranged on a plurality of substrates. For example, a part of the control unit 30 may be disposed on the cleaning device 200 or the ventilation device 300.

  The control unit 30 performs linked control that links one operation of the cleaning device 200 and the ventilation device 300 with the other operation. That is, the control unit 30 controls the other operation based on one operation state of the cleaning device 200 and the ventilation device 300. Details of the interlock control will be described later.

  In addition, the bathroom system 100 includes an operation unit 35 (remote control) for a user to operate the cleaning device 200 and the ventilation device 300. The operation unit 35 is provided in 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 wireless. The user can start / stop the operation of the cleaning device 200 and the ventilation device 300 or change the operation setting by operating a button (switch) provided on the operation unit 35. 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.

With reference to FIG. 3, an example (cleaning apparatus 200a) of the cleaning apparatus 200 will be described.
Drawing 3 is a mimetic diagram which illustrates washing equipment of a bathroom system concerning an embodiment.
FIG. 3 shows a state in which the vicinity of the counter 530 of the bathroom 500 is viewed from the side.
The cleaning device 200 a has a nozzle portion 10 a that protrudes below the counter 530. The nozzle portion 10 a is disposed at a position separated from the washing floor 520 below 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). Thereby, tap water is supplied from the water supply pipe 51 to the cleaning device 200a.

  Inside the counter 530 (between the top plate 531 and the lower cover 532), a first strainer 53a, a first electromagnetic valve 54a, a second electromagnetic valve 54b, a pressure regulating valve 55, a vacuum breaker 57, The stop valve 56, the functional water generator 20, the second strainer 53b, and the electric motor 17 are provided. The 1st strainer 53a is connected with the water supply pipe 51, and the flow path of tap water has branched into two in the downstream of the 1st strainer 53a.

  One flow path on the downstream side of the first strainer 53a supplies tap water (which is an example of cleaning water) directly to the nozzle portion 10a via the first electromagnetic valve 54a. Tap water is supplied to the nozzle part 10a by opening the first electromagnetic valve 54a.

  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 (which is an example of cleaning water) to the nozzle portion 10a.

  The first solenoid valve 54a and the second solenoid valve 54b perform an operation of opening the tap water flow path and an operation of closing the tap water flow path, respectively. The pressure regulating valve 55 controls the pressure of the supplied tap water. Thereby, the flow volume of the tap water supplied to the functional water production | generation part 20 mentioned 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 functional water supplied to the nozzle unit 10a is adjusted. You may adjust the flow volume of tap water using the 2nd solenoid valve 54b.

  The functional water is, for example, sterilized water having a function of sterilization (or sterilization). Functional water contains hypochlorous acid, for example. In this example, the functional water generator 20 is an electrolysis chamber (electrolyzer) having an anode and a cathode. The functional water generating unit 20 generates a low concentration hypochlorous acid by applying a voltage between the anode and the cathode and electrolyzing tap water flowing between the electrodes. Since tap water contains chloride ions, hypochlorous acid is generated by electrolyzing the chloride ions.

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

  At least a part of the strainers 53a and 53b, the electromagnetic 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 are provided outside the counter 530 and outside the bathroom 500. It is also possible.

  The first electromagnetic valve 54 a, the second electromagnetic valve 54 b, the pressure regulating valve 55, and the functional water generator 20 are appropriately controlled by the controller 30. Thereby, the sprinkling of the tap water from the nozzle part 10a and the sprinkling of the functional water from the nozzle part 10a can be controlled independently of each other.

  Specifically, the first electromagnetic valve 54 a and the second electromagnetic valve 54 b open and close the tap water flow path based on a signal from the control unit 30. Thereby, the flow volume of the tap water supplied downstream is controlled. The functional water generator 20 switches the electrolysis chamber ON / OFF and the like based on a signal from the controller 30. Thus, the control part 30 can control the density | concentration of the various structural components in functional water, the flow volume of the wash water discharged (flow volume per unit time), and the total amount of the wash water discharged.

  Moreover, the nozzle part 10a is provided with the water discharge port 12 (opening). The nozzle part 10a discharges the wash water (tap water and functional water) supplied from the upstream from the spout 12 to the wash floor 520 of the bathroom 500 by water pressure. Thereby, dirt (for example, sebum from human body, dirt, hair, etc.) on the wash floor 520 can be washed away to the drain outlet 521 or the surface of the wash floor 520 can be sterilized. The washing water discharged from the nozzle part 10a is, for example, in the form of a mist.

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

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

With reference to FIG.4 and FIG.5, an example of the ventilation apparatus 300 is demonstrated.
Drawing 4 is a mimetic diagram which illustrates the principal part composition of the ventilation equipment of the bathroom system concerning an embodiment. In FIG. 4, an air path system and an electrical system are shown together.
FIG. 5 is a cross-sectional view illustrating a ventilation device of the bathroom system according to the embodiment.

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

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

  An 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 inlet 312 and the outlet 314. The inlet 312 and the outlet 314 communicate with the bathroom 500, respectively. As a result, the air passage 316 communicates with the interior of the bathroom 500 via the inlet 312 and the outlet 314.

  The fan 322 is provided inside the air passage 316. The fan 322 includes a motor, for example. 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 arrow A1 in FIGS. 4 and 5, the suction port 312 sucks in 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 an arrow A <b> 2 shown in FIGS. 4 and 5, the air outlet 314 blows out air sucked by the air inlet 312 into the bathroom 500.

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

  When the heating unit 318 is energized, the heating unit 318 heats the air in the air passage 316. That is, the heating unit 318 heats the air sucked by the suction port 312. Thereby, the heated air can be blown out from the blower outlet 314.

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

  The control unit 30 is connected to the fan 322, the heating unit 318, and the damper 336. The control unit 30 controls the operation (energization) of the fan 322, the operation (energization) of the heating unit 318, and the operation of the damper 336. Accordingly, the ventilation device 300 performs “ventilation operation” for ventilating the air inside the bathroom 500, “heating operation” for heating the air inside the bathroom 500, or sending warm air into the bathroom 500 to send the bathroom 500 or the bathroom. A “dry operation” may be performed to dry the clothing in 500.

  In the ventilation operation, the control unit 30 closes the outlet 314 and opens the outlet 334 with the damper 336. 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 from the discharge port 334 to the outside or the like. Thereby, replacement of the air in the bathroom 500 (ventilation) can be performed.

  In the heating operation, the control unit 30 closes the discharge port 334 by the damper 336 and opens the air outlet 314. In this state, the control unit 30 operates the fan 322 and operates the heating unit 318 (energizes the heater). The air sucked from the inside of 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. Thereby, since the air in the bathroom 500 is heated by the heating means 318 while circulating, the temperature in the bathroom 500 rises.

  In the drying 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 unit 318. Part of the air sucked from the bathroom 500 by the fan 322 is discharged from the discharge port 334 to the outside or the like. The remaining part of the sucked air is heated by the heating means 318 and then blown out from the air outlet 314 into the bathroom 500 and circulates in the bathroom 500.

  In the embodiment, the ventilation device 300 may not include the heating unit 318 (heater), and may not perform the heating operation and the drying operation. The ventilation device 300 only needs to have a ventilation means having an arbitrary configuration that can replace 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 control) has a plurality of switches (buttons) such as a first ventilation switch 35a, a second ventilation switch 35b, a cleaning interlock switch 35c, a bathtub cleaning switch 35d, and a floor cleaning switch 35e.

  The control unit 30 has a ventilation mode in which the bathroom 500 is ventilated by the ventilation device 300. When the user operates one of the first ventilation switch 35a and 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 operates the ventilation means (fan 322) of the ventilation device 300, and causes the ventilation device 300 to execute the above-described ventilation operation.

  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 performs weak ventilation (or 24-hour ventilation), and the second mode is an operation mode in which the ventilation device 300 performs 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 power, and causes the ventilation device 300 to execute 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 power, and causes the ventilation device 300 to execute the ventilation operation.

  The second power (watts) of the fan 322 in the second mode is larger than the first power (watts) of the fan 322 in the first mode. Therefore, in the second mode, the rotational speed of the motor of the fan 322 is higher than that in the first mode. Accordingly, 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 cleaning mode in which at least a part of the washing floor 520, the walls (first to fourth walls 541 to 544) and the bathtub 510 is cleaned by the cleaning device 200. When the user operates any of the cleaning interlock 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 execute a bathroom cleaning operation (water discharge operation to the bathroom).

  The cleaning mode includes, for example, a floor cleaning mode, a bathtub cleaning mode, and a cleaning interlock 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 floor 520 is started. When the user operates the bathtub cleaning switch 35d, the control unit 30 executes the bathtub cleaning mode. Thereby, a signal is sent from the control unit 30 to a cleaning device 200b (tub cleaning device) described later, and cleaning of the bathtub 510 is started. Further, when the user operates the cleaning interlock switch 35c, the cleaning interlock mode is executed. Thereby, 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 (tub cleaning device) are interlocked with each other. While done at the same time. Thereby, the time which the bathroom 500 requires for cleaning can be shortened, and the effort which a user operates the operation part 35 can be saved. In the embodiment, there may be one cleaning device.

Next, interlocking control between the cleaning device 200 and the ventilation device 300 by the control unit 30 will be described.
In the interlock 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 drawings.

FIG. 7A to FIG. 7C are timing charts illustrating the operation of the bathroom system according to the embodiment.
In the timing chart, the horizontal axis represents time (t). FIG. 7A shows the timing when the user operates the cleaning switch (any one of the cleaning interlock switch 35c, the bathtub cleaning switch 35d, and the 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 interlock mode is executed. When the cleaning mode is OFF, none of the floor cleaning mode, the bathtub cleaning mode, and the cleaning interlock mode is executed. That is, when the cleaning mode is OFF, the bathroom 500 is not cleaned (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, the user operates the cleaning switch of the operation unit 35 at time T1. Then, as shown in FIG. 7B, at time T1, the control unit 30 starts the cleaning mode. The cleaning mode ends at time T3 after time T1. That is, the cleaning operation of the cleaning device 200 is performed between time T1 and time T3, and cleaning water is discharged from the cleaning device 200 into the bathroom 500. And as shown in FIG.7 (c), the control part 30 performs ventilation mode during execution of washing | cleaning mode, ie, between time T1-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 cleaning mode. That is, the ventilation operation of the ventilation device 300 is performed while the cleaning device 200 is discharging water to the washing floor 520 or the bathtub 510. Thereby, since the washing | cleaning apparatus 200 is discharging water, the raise of the humidity in the bathroom 500 can be suppressed. Therefore, it is possible to easily evaporate the remaining water of the cleaning water discharged from the cleaning device 200. Thereby, generation | occurrence | production of the black mold in the bathroom 500 can be suppressed effectively.

  The start of the ventilation mode may be simultaneously with the start of the cleaning mode (time T1). Thereby, since ventilation in the bathroom 500 is performed from the start of the cleaning mode, an increase in humidity in the bathroom can be further suppressed. The end of the ventilation mode may be before the end of the cleaning mode (time T3) or after the end of the cleaning mode.

FIG. 8A to FIG. 8D are timing charts illustrating the operation of the bathroom system according to the embodiment.
FIG. 8A shows the timing when 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, the user operates the cleaning switch of the operation unit 35 at time T4. Then, as shown in FIG. 8B, at time T4, the control unit 30 starts the cleaning mode. The cleaning mode ends at time T6 after time T4. That is, the cleaning operation of the cleaning device 200 is performed between time T4 and time T6, and cleaning water is discharged from the cleaning device 200 into the bathroom 500.

  In this example, as shown in FIGS. 8C and 8D, the first mode (weak ventilation) is executed before the start of the cleaning mode (time T4), and the second mode ( (Strong ventilation) is not implemented. 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 time T5 after time T4, and ends at time T6. The process 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 cleaning mode starts at time T4 and ends at time T6, as shown in FIGS. 8A and 8B.
The humidity H1 indicates a change in humidity in the bathroom when the ventilation mode is switched from the first mode to the second mode at the time T5 as described with reference to FIGS. 8C and 8D. .
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 a 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 time T4 to time T5, and ventilation is not performed after time T5.

  As shown in FIG. 9, after 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 an increase in humidity in the bathroom 500 and to make it easier to evaporate the remaining water of the cleaning water. it can. Thereby, generation | occurrence | production of the black mold in the bathroom 500 can be suppressed more.

  In the example of FIG. 8, the switching from the first mode to the second mode may be performed simultaneously with the start of the cleaning mode (time T4). Thereby, since ventilation is performed in the 2nd mode with big air volume from the start of washing | cleaning mode, the raise of the humidity in a bathroom can be suppressed more.

FIG. 10A to FIG. 10C are timing charts illustrating the operation of the bathroom system according to the embodiment.
FIG. 10A shows the timing when 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, the user operates the cleaning switch of the operation unit 35 at time T7. Then, as shown in FIG. 10B, at time T7, the control unit 30 starts the cleaning mode. The cleaning mode ends at time T9 after time T7. And as shown in FIG.10 (c), the control part 30 performs ventilation mode during execution of washing | cleaning mode, ie, between time T7-time T9.

  In this example, the ventilation mode is started at time T8 after time T7. Further, the ventilation mode ends at time T10 after time T9 when the cleaning mode ends. That is, the control unit 30 stops the ventilation mode after a predetermined time P1 has elapsed since the cleaning mode was completed. Thereby, since ventilation mode is continued until predetermined time passes after completion | finish of washing | cleaning mode, the raise of the humidity in the bathroom 500 can be suppressed even after completion | finish of washing | cleaning mode. Thereby, the remaining water of the cleaning water discharged from the cleaning 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 according to, for example, the speed at which the humidity in the bathroom 500 is lowered by the ventilation mode or the speed at which the wash 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 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 the ventilation mode has been executed when the cleaning switch is pressed, and if the ventilation mode has been executed, either the first mode or the second mode. Remembers if was executed.
When the cleaning switch is pressed (when the cleaning mode is started), if the ventilation mode is not executed, either the first mode or the second mode is executed during the cleaning mode. May be.

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

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

  When the second predetermined time has elapsed since the end of the cleaning mode (step S109: YES), the control unit 30 shifts to the ventilation mode stored in step S102 (step S110). That is, when the second mode is executed when the cleaning switch is pressed, the control unit 30 continues the second mode in step S110. If the first mode is being executed when the cleaning switch is pressed, the control unit 30 transitions from the second mode to the first mode in step S110.

  It should be noted that the second predetermined time in step S109 is arbitrarily determined as appropriate, similarly to the predetermined time P1 described with reference to FIG. The second predetermined time may be zero, and the control unit 30 may shift to the stored ventilation mode simultaneously with the end of the cleaning mode.

FIG. 12A to FIG. 12D are timing charts illustrating the operation of the bathroom system according to the embodiment. These figures represent an example of the operation described with reference to FIG.
FIG. 12A shows the timing when 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. 12C 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, the user operates the cleaning switch of the operation unit 35 at time T11. Then, as illustrated in FIG. 12B, at time T11, the control unit 30 starts the cleaning mode. The cleaning mode ends at time T14 after time T11.

  In this example, as shown in FIGS. 12C and 12D, the first mode is executed before the start of the cleaning mode and at time T11. Therefore, the control part 30 memorize | stores that 1st mode was performed as demonstrated regarding 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.

  Thereafter, 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. 12C and 12D, at time T14, the ventilation mode is switched from the second mode to the first mode.

As described above, in the example described with reference to FIGS. 11 and 12, when the controller 30 has executed either the first mode or the second mode before the execution of the cleaning mode, Run the mode that was running before the mode was run.
That is, the ventilation mode before the cleaning mode is started is automatically executed by the control unit 30 after the cleaning mode ends. Thereby, even if it is a case where ventilation mode is switched during washing | cleaning mode, a user does not need to return to the original ventilation mode, and it 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 reference to FIG.

  Thereafter, when the cleaning mode is being executed, if the control unit 30 stores 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 first mode is being executed when the cleaning mode is started, the execution of the first mode is maintained, and when the second mode is being executed, the second mode is executed. maintain. On the other hand, when the cleaning mode is being executed, the control unit 30 executes the second mode when storing 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 reference 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, when ventilation is not performed at the start of the cleaning mode, it is considered that the humidity in the bathroom 500 is relatively high at the start of the cleaning mode, so the second mode with a large air volume is executed.

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

  Thus, based on the state of the ventilation mode at the start of the cleaning mode, efficient ventilation can be performed by controlling the air volume of the ventilation during the cleaning mode. For example, by executing the first mode during execution of the cleaning mode, it is possible to suppress an increase in power consumption compared to the case of executing the second mode. In addition, by executing the first mode during the execution of the cleaning mode, it is possible to suppress the operation sound (fan operation sound) of the ventilation device 300 as compared to the case of executing the second mode.

With reference to FIG. 14, another example (cleaning device 200b) of the cleaning device 200 will be described. FIG. 14 is a schematic view illustrating a cleaning device 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 into the bathtub 510.
The cleaning device 200b includes a flow rate detection 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 path 608. Thereby, tap water that has passed through the water supply channel 608 is supplied from the water supply pipe 51 to the cleaning nozzle 601.

  In the water supply channel 608, a flow rate detection device 604, a water amount control device 605, and an electromagnetic valve 606 are provided in this order from the upstream side. The electromagnetic valve 606 performs an operation of opening the water supply channel 608 and an operation of closing the water supply channel 608. When the electromagnetic valve 606 is opened, tap water is supplied to the cleaning nozzle 601, and when the electromagnetic valve 606 is closed, water supply to the cleaning nozzle 601 is stopped.

  The cleaning nozzle 601 is provided in the bathtub 510. The water outlet 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 into the bathtub 510 from the water outlet 601a by water pressure. Thereby, the dirt in the bathtub 510 can be washed away to the drain outlet 512 of the bathtub 510. The cleaning water discharged from the cleaning nozzle 601 is, for example, in the form of a mist.

  The drain plug driving motor 624 can operate the thrust lock mechanism 623 via the wire cable 621. By operating the thrust lock mechanism 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 manual switch 620 provided on the rim or the like of the bathtub 510 to operate the thrust lock mechanism 623 and open / close the drain port 512.

  The flow rate detection device 604, the water amount control device 605, the electromagnetic valve 606, and the drain plug driving 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 electromagnetic valve 606 opens and closes the water supply channel 608 based on a signal from the control unit 30. Thereby, the water discharge and water stop of the washing nozzle 601 are switched. Further, the drain plug driving motor 624 opens and closes the drain port 512 based on a 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. Thereby, the water (hot water) remaining in the bathtub 510 is drained. After a predetermined time has elapsed after the drainage port 512 is opened and the drainage is performed, the control unit 30 opens the electromagnetic valve 606. Thereby, washing water is discharged from the washing nozzle 601 into the bathtub 510, and the inside of the bathtub 510 can be washed.

  Note that the cleaning device 200b may discharge functional water not only with tap water but also with the same configuration as the cleaning device 200a. Further, the cleaning device 200b may include a detergent tank and a pump inside, and spray the detergent from the cleaning nozzle 601 into the bathtub 510.
