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 heating 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. As a result, 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 heating device 300 is provided in the bathroom 500 and has a heating means (heater) for heating the bathroom. For example, the heating device 300 has a heater and a fan, and can heat, dry, and ventilate 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 heating device 300. The connection between the control unit 30 and the cleaning device 200 and the connection between the control unit 30 and the heating device 300 may be a wired connection or a wireless connection. Each of the cleaning device 200 and the heating 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 heating device 300.

The control unit 30 performs interlocking control in which one operation of the cleaning device 200 and the heating 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 heating 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 heating 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 heating 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 heating 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 heating 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 heating 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 heating device of the bathroom system according to the embodiment.

As shown in FIG. 4, the heating 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 heating 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 heating device 300 is located above the ceiling 545 and is arranged outside the bathroom 500. The lower part of the heating device 300 is located below the ceiling 545 and is arranged inside the bathroom 500.

The air passage 316 shown in FIG. 4 is an air passage provided inside the housing 311 of the heating 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 heating device 300 may be further provided with 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 heating device 300 executes a "heating operation" for warming the air inside the bathroom 500 and a "drying operation" for sending warm air to the inside of the bathroom 500 to dry the clothes in the bathroom 500 and the bathroom 500. be able to.

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.

Further, the heating device 300 may be capable of performing "ventilation operation" to ventilate the air inside the bathroom 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).

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 heating switch 35a, a drying switch 35b, a cleaning interlocking switch 35c, a bathtub cleaning switch 35d, and a floor cleaning switch 35e.
The heating switch 35a and the drying switch 35b are switches for operating the heating device 300. When the user operates the heating switch 35a, a signal is sent from the control unit 30 to the heating device 300, and the heating operation is started (or stopped). Similarly, when the user operates the drying switch 35b, a signal is sent from the control unit 30 to the heating device 300, and the drying operation is started (or stopped).

The cleaning interlocking switch 35c, the bathtub cleaning switch 35d, and the floor cleaning switch 35e are cleaning switches for operating the cleaning device 200. When the user operates the floor cleaning switch 35e, 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. When the user operates the bathtub cleaning switch 35d, 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, a signal is sent from the control unit 30 to the cleaning device 200a and the cleaning device 200b, and the cleaning interlocking mode is executed. In the cleaning interlocking mode, the cleaning operation of the cleaning device 200a (floor cleaning device) and the cleaning operation of the cleaning device 200b (bathtub cleaning device) are performed simultaneously while interlocking with each other. 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 heating device 300 by the control unit 30 will be described.
In this interlocking control, the control unit 30 is in a stopped state of the heating means 318 when the heating means 318 is stopped, based on the state of the heating means 318 when the washing water discharge operation by the cleaning device 200 is started. If the heating means 318 is operating, the output of the heating means 318 is reduced. An example of this interlocking control will be described with reference to FIG. 7.

FIG. 7 is a flowchart illustrating the operation of the bathroom system according to the embodiment.
When the user operates the cleaning switch (one of the cleaning interlocking switch 35c, the bathtub cleaning switch 35d, and the floor cleaning switch 35e) of the operation unit 35, the cleaning device 200 starts the cleaning operation (step S101). Along with this, the cleaning device 200 starts the operation of discharging the cleaning water into the bathroom 500.

The control unit 30 determines the state of the heating means 318 when the washing water discharge operation by the washing device 200 is started (step S102). The state of the heating means 318 is whether the heating means 318 is operating or stopped. The state in which the heating means 318 is operating is, for example, a state in which the heater is energized. The state in which the heating means 318 is stopped is, for example, a state in which the heater is not energized.

When the heating means 318 is stopped in step S102 (step S102: NO), the control unit 30 maintains the stopped state of the heating means 318, that is, the state of zero output (step S103). After that, the cleaning operation (water discharge operation) by the cleaning device 200 ends (step S105).

On the other hand, when the heating means 318 is operating in step S102 (step S102: YES), the control unit 30 lowers the output of the heating means 318 (step S104). After that, the cleaning operation (water discharge operation) by the cleaning device 200 ends (step S105).

As described above, when the heating means 318 is de-energized when the water discharge operation of the cleaning device 200 is started, the control unit 30 de-energizes (stops) the heating means 318 during the water discharge operation of the cleaning device 200. To maintain. On the other hand, when the heating means 318 is energized when the water discharge operation of the cleaning device 200 is started, the control unit 30 starts the water discharge operation of the output of the heating means 318 during the water discharge operation of the cleaning device 200. Make it lower than the output at the time.

The output of the heating means 318 is, for example, the power consumption (watt: W) of the heater. The timing for lowering the output may be substantially the same as when the water discharge operation is started, or may be after the water discharge operation is started (for example, immediately after). Further, "when the water discharge operation is started" may be, for example, when the cleaning switch of the operation unit 35 is operated, that is, when the cleaning operation is started.

When the temperature in the bathroom rises due to the heating device while the cleaning device is discharging water into the bathroom, the washing water discharged from the cleaning device becomes steam, and the amount of water vapor contained in the air in the bathroom increases. When air containing a large amount of water vapor reaches the ceiling or wall at a low temperature, the temperature difference causes dew condensation on the ceiling or wall. Mold may form on the part where water droplets adhere due to dew condensation.

In particular, before cleaning, dirt (for example, sebum, dirt, etc.) is attached to the bathroom. Therefore, the washing water that has landed in the bathroom during washing contains dirt. When the washing water containing dirt becomes water vapor, the water vapor also contains water vapor, so that the water vapor adheres to the ceiling and walls of the bathroom. Such stains provide nutrients for mold. Therefore, if the heating means is operated during the water discharge operation of the cleaning device, it is considered that mold is particularly likely to occur.

On the other hand, according to the embodiment, the heating means 318 is stopped or the output of the heating means 318 is lowered during the operation of discharging the washing water by the washing device 200 by the interlocking control described above. As a result, it is possible to suppress that the washing water discharged from the washing device 200 becomes water vapor due to the temperature rise in the bathroom 500, and it is possible to suppress an increase in the amount of water vapor contained in the air in the bathroom 500. Therefore, it is possible to suppress the occurrence of dew condensation in the bathroom 500.

Further, the range of "reducing the output of the heating means" includes zero output, that is, de-energizing the heater. That is, the control unit 30 may stop the heating means 318 when the heating means 318 is operating based on the state of the heating means 318 when the water discharge operation is started. As a result, an increase in the amount of water vapor contained in the air in the bathroom 500 can be further suppressed, and the occurrence of dew condensation in the bathroom can be further suppressed.

The operation is invalidated or not accepted. As a result, the temperature inside the bathroom 500 can be suppressed from rising during the water discharge operation, and the occurrence of dew condensation in the bathroom 500 can be further suppressed.

Note that "operation is not accepted" means that, for example, the control unit 30 does not receive the signal transmitted from the operation unit 35. Further, "the operation is invalidated" means that, for example, the control unit 30 does not transmit a command based on a signal from the operation unit 35 to the heating device 300.

FIG. 9 is a flowchart illustrating the operation of the bathroom system according to the embodiment.
When the user operates the cleaning switch (one of the cleaning interlocking switch 35c, the bathtub cleaning switch 35d, and the floor cleaning switch 35e) of the operation unit 35, the cleaning device 200 starts the cleaning operation (step S101). Along with this, the cleaning device 200 starts the operation of discharging the cleaning water into the bathroom 500.

After that, during the water discharge operation (cleaning operation) of the cleaning device 200, when the heating switch 35a is pressed (step S301: YES), the control unit 30 is after the end of the cleaning operation by the cleaning device 200 (step S105). , The heating operation is started (step S303).

Further, during the water discharge operation of the cleaning device 200, when the drying switch 35b is pressed (step S304: YES), the control unit 30 performs the drying operation after the cleaning operation by the cleaning device 200 is completed (step S105). Start (step S306). It should be noted that steps S102 to S104 described with respect to FIG. 7 are also executed between steps S101 and S105 shown in FIG.

As described above, in this example, when the operation unit (heating switch 35a, drying switch 35b, etc.) is operated during the water discharge operation of the cleaning device 200, the heating means 318 is operated after the water discharge operation of the cleaning device 200 is completed. It is started or the output of the heating means is increased. As a result, the temperature inside the bathroom 500 can be suppressed from rising during the water discharge operation, and the occurrence of dew condensation in the bathroom 500 can be further suppressed.

Further, after the water discharge operation of the cleaning device 200 is completed, the operation of the heating means 318 is started or the heating means 318 is started according to the operation during the water discharge operation without the user operating the operation unit 35. The output of is increased. Therefore, it is not necessary for the user to operate the operation unit 35 again after the water discharge operation of the cleaning device 200 is completed, which is convenient.

Further, in the example shown in FIG. 9, after the cleaning operation is completed in step S105, the control unit 30 counts a predetermined time before executing steps S303 and S306 (steps S302 and S305).

That is, when the operation unit (heating switch 35a, drying switch 35b, etc.) is operated during the water discharge operation, the operation of the heating means 318 is started or the output of the heating means 318 is started after a predetermined time has elapsed from the completion of the water discharge operation. Is increased.

As a result, the cleaning water discharged from the cleaning device 200 into the bathroom 500 can be drained during a predetermined time after the water discharge operation of the cleaning device 200 is completed. Then, after the washing water in the bathroom 500 is drained to some extent, the operation of the heating means 318 is started, or the output of the heating means 318 is increased. As a result, it is possible to suppress that the washing water discharged from the washing device 200 becomes water vapor due to the temperature rise in the bathroom 500, and it is possible to suppress an increase in the amount of water vapor contained in the air in the bathroom 500. Therefore, it is possible to suppress the occurrence of dew condensation in the bathroom 500.

Although this predetermined time is arbitrary, it can be appropriately set based on the time required for draining the washing water. The predetermined time can be, for example, about 10 to 20 minutes.

Another example of the cleaning device 200 (cleaning device 200b) will be described with reference to FIG. FIG. 10 is a schematic diagram illustrating the cleaning equipment of the bathroom system according to the embodiment.

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.
