  The air path switching unit 39 includes a damper 40 that switches the air path. The damper 40 receives a driving force of a damper motor, which will be described later, via a cam 40a, and rotates around a shaft 40b to perform an opening / closing operation. The fan case 37 communicates with the air path switching unit 39 and includes a blower outlet 41 on the lower surface, and communicates with the air path switching unit 39 and includes an exhaust port 42 on one side surface. In this case, depending on the position of the damper 40, an air passage communicating from the suction port 38 to the air outlet 41 or an air passage communicating from the suction port 38 to the exhaust port 42 is formed.

  FIG. 6A shows a state in which the damper 40 is fully closed. When the damper 40 is fully closed, the air passage to the exhaust port 42 is blocked, and a circulation air passage 43 a communicating from the suction port 38 to the blower outlet 41 is formed. For this reason, the position where the damper 40 is fully closed is referred to as the circulation position of the damper 40.

  FIG. 6B shows a state where the damper 40 is fully opened. When the damper 40 is fully opened, the air path to the air outlet 41 is blocked, and a ventilation air path 43b communicating from the suction port 38 to the exhaust port 42 is formed. For this reason, the position where the damper 40 is fully opened is referred to as a ventilation position of the damper 40.

  FIG. 6C shows a state in which the damper 40 is at an intermediate position between the circulation position and the ventilation position. When the damper 40 is set at an intermediate position between the circulation position and the ventilation position, both a circulation air path 43a communicating from the intake port 38 to the outlet 41 and a ventilation air path 43b communicating from the intake port 38 to the exhaust port 42 are formed. .

The ion generator 44 is an example of an ion generating means, and an ion emission surface is exposed to a circulation air passage 43a formed by setting the damper 40 to a circulation position or a circulation ventilation position.

The ion generator 44 generates both positive ions and negative ions or negative ions. The principle of generation of positive ions and negative ions is that a corona discharge is caused by boosting and applying an AC voltage taken from a household AC power source or the like between a pair of electrodes opposed so as to interpose a dielectric, Oxygen or water in the air is ionized by receiving energy by ionization, and H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). The main ions are emitted.

These H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of the floating bacteria and chemically react to generate H ₂ O ₂ or .OH as an active species. Since H ₂ O ₂ or .OH exhibits a very strong activity, they can surround and inactivate airborne bacteria in the air. Here, .OH is one kind of active species, and represents radical OH.

  Accordingly, in association with the operation of the fan unit 32, approximately the same number of positive ions and negative ions are generated, and air containing approximately the same number of positive ions and negative ions is blown, thereby allowing floating bacteria contained in the circulating air to 1 can inactivate both floating bacteria in the air in the bathroom 101 shown in FIG.

  The heater unit 33 is an example of a heating unit constituted by an electric heater, and is provided in the above-described air outlet 41. As shown in FIG. 6A, when the position of the damper 40 is set to the circulation position and the fan 35 is rotationally driven by the fan motor 36, air is sucked from the suction port 38 and blown out from the blower outlet 41 through the circulation air passage 43a. When the heater unit 33 is energized, the heater unit 33 is heated to heat the air passing through the outlet 41 and warm air is blown out from the outlet 41. Here, as the heater section 33, for example, a PTC (Positive Temperature Coefficient) heater can be used.

  A temperature detection sensor 69 is attached to a portion of the fan case 37 corresponding to the suction port 38. The temperature detection sensor 69 is for detecting the temperature of the bathroom 101.

  As shown in FIG. 5, the main body case 34 is open at the lower surface so that the suction port 38 and the air outlet 41 of the fan portion 32 are exposed. The front panel 26 is attached to the lower surface opening of the main body case 34.

  The front panel 26 is configured to be detachable from the main body case 34. The front panel 26 includes a suction grill 45 facing the suction port 38 of the fan part 32, and a blow grill 46 facing the blower outlet 41 of the fan part 32. A filter 47 is replaceably attached to the back side of the suction grill 45 of the front panel 26.

  The main body case 34 includes an exhaust duct connecting portion 48 that communicates with the exhaust port 42 of the fan portion 32 on one side surface. As shown in FIG. 1, the exhaust duct 8 is connected to the exhaust duct connection portion 48.

  The operation of the bathroom air conditioner 3 will be described. When the fan motor 36 is driven to rotate, the fan 35 of the fan unit 32 rotates. When the fan 35 rotates, the air in the bathroom 101 is sucked from the suction port 38 of the fan part 32 through the suction grill 45 of the front panel 26.

  When the position of the damper 40 is at the circulation position shown in FIG. 6A, the circulation air passage 43a from the suction port 38 to the blowout port 41 is formed in the fan portion 32, so that the air sucked from the suction port 38 The air passes through the passage 43a and is blown out into the bathroom 101 from the air outlet 41 through the air outlet grill 46 of the front panel 26.

  Since the heater portion 33 is disposed at the outlet 41 of the circulation air passage 43a, the air passing through the circulation air passage 43a is heated by the heater portion 33 and blown out from the outlet grill 46 by driving the heater portion 33. . As a result, when the fan motor 36 is rotationally driven with the damper 40 as the circulation position, when the heater unit 33 is driven, hot air is blown into the bathroom 101 while circulating the air in the bathroom 101. it can.

  When the position of the damper 40 is in the ventilation position shown in FIG. 6B, the ventilation air passage 43b from the suction port 38 to the exhaust port 42 is formed in the fan part 32, so that the air sucked from the suction port 38 is ventilated. The air passes through the passage 43b and the exhaust port 42, and further passes through the exhaust duct 8 shown in FIG. Thereby, when the fan motor 36 is rotationally driven with the damper 40 as the ventilation position, steam and moisture in the bathroom 101 are exhausted.

  When the position of the damper 40 is in the circulation ventilation position shown in FIG. 6C, both the circulation air passage 43 a from the suction port 38 to the blowout port 41 and the ventilation air passage 43 b from the suction port 38 to the exhaust port 42 in the fan portion 32. Thus, a part of the air sucked from the suction port 38 passes through the circulation air passage 43a and is blown out from the blower outlet 41 into the bathroom 101 through the blowout grill 46 of the front panel 26, and the other is a ventilation airway. 43 b and the exhaust port 42, and further exhausted from the exhaust grill 8 a to the outside through the exhaust duct 8 shown in FIG. 1.

  Thereby, when the fan motor 36 is rotationally driven with the damper 40 as the circulation ventilation position, when the heater unit 33 is not driven, the steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101. Is done. In addition, when the heater unit 33 is driven, steam and moisture in the bathroom 101 are exhausted while circulating air in the bathroom 101 and blowing hot air into the bathroom 101.

  The mist generator 2 is connected to the downstream side of the mixing valve 68. That is, the electromagnetic valve unit 2A of the mist generator 2 is connected to the water supply pipe 2a on the downstream side of the mixing valve 68 (see FIG. 1). The temperature of the hot water supplied to the mist generator 2 is adjusted by switching the mixing ratio of the hot water whose temperature has been raised by the heating device 67 and the water supplied from the mist water supply pipe 63b.

  Next, operation | movement of the heat pump hot-water supply apparatus 4 is demonstrated.

  Water is supplied from the water supply pipe 63 to the tank 60 of the hot water storage tank unit 54. The water supplied to the tank 60 is supplied to the water heat exchanger 56 of the heat pump unit 53 through the cold water pipe 61b.

  In the heat pump unit 53, the air is supplied to the air heat exchanger 55 by the fan 55a, heat exchange is performed with the refrigerant flowing through the refrigerant pipe 57, and the temperature of the refrigerant rises. The refrigerant whose heat has been exchanged by the air heat exchanger 55 is compressed by the compressor 58, whereby the temperature further rises.

  The refrigerant that has been compressed by the compressor 58 and raised in temperature is supplied to the water heat exchanger 56. Thereby, in the water heat exchanger 56, heat exchange is performed between the refrigerant whose temperature has increased due to heat exchange and compression with the atmosphere and the water supplied from the hot water storage tank unit 54, and hot water is generated. . The refrigerant heat-exchanged by the water heat exchanger 56 is expanded by the expansion valve 59 to lower the temperature, and is supplied to the air heat exchanger 55 again.

  Moreover, the hot water produced | generated by exchanging heat with the water heat exchanger 56 is returned to the tank 60 by the hot water piping 61a. Accordingly, the tank 60 stores hot water and water in a state where the upper side is stratified with a high temperature on the upper side and a lower temperature on the lower side. The hot water stored in the tank 60 is taken in by the intake pipe 62. Here, when the temperature of the supplied hot water is high, the switching valve 62c takes hot water from the high temperature portion intake pipe 62a, and when the temperature of the supplied hot water is low, the hot water is taken from the intermediate temperature portion intake pipe 62b.

  The hot water taken by the water intake pipe 62 is mixed with the water supplied from the branch water supply pipe 63 b by the hot water supply mixing valve 64. The temperature of hot water supplied from the hot water supply pipe 65 is adjusted by switching the mixing ratio of hot water and water with the hot water supply mixing valve 64. The hot water supplied from the hot water supply pipe 65 is distributed to the bathroom 101, the washroom 102, and the kitchen 103.

  On the other hand, the hot water supplied from the hot water supply pipe 65 is supplied to the mist generator 2 through the mist hot water supply pipe 65a (water supply pipe 2a) after the temperature and the hot water supply pressure are controlled by the temperature / pressure control device 52A. That is, the temperature / pressure control device 52A raises the hot water supply pressure of the hot water supplied to the mist hot water supply pipe 65a by the pressurization device 66. Thereby, the hot water supplied from the heat pump water heater 51A is raised to a hot water supply pressure suitable for generation of mist in the mist generator 2.

  The hot water supplied to the mist hot water supply pipe 65a and having the hot water supply pressure raised by the pressurizing device 66 is heated by the heating device 67 to raise the temperature. The hot water supplied from the heat pump water heater 51A is limited to the hot water supply temperature set in the bathroom 101 or the like, but the temperature is raised by the heating device 67 of the temperature / pressure control device 52A, so that the heat pump water heater 51A side Regardless of the limitation of the hot water supply temperature, the temperature of the hot water supplied to the mist generator 2 is controlled.

  For example, the temperature of the hot water supplied to the mist generator 2 can be raised from the hot water supply temperature of the hot water supplied from the heat pump water heater 51A. Further, by mixing the hot water supplied from the mist hot water supply pipe 65a with a controlled hot pressure and the water supplied from the mist hot water supply pipe 63b by the mixing valve 68, the mixing ratio of the hot water and water is switched to generate mist. The temperature of the hot water supplied to the apparatus 2 can be controlled. For example, it is possible to supply only water.

  The hot water from the mist hot water supply pipe 65a may be supplied to the mist generator 2 as it is without providing the pressurizing device 66, the heating device 67, and the mixing valve 68.

<Operation of bath mist (silver ion mist on) mode>
When the silver ion mist button 7c is pushed by the mist remote controller 7 and the silver ion mist is turned on, and then the bath mist button 7b is pushed and the bath mist is turned on, or by the air conditioning remote controller 6, the silver ion mist button 6c is turned on. When the bath mist button 6b is pressed and the bath mist is turned on, the bath mist (silver ion mist on) mode is entered and the operation of this mode is started.

  FIG. 11 is a flowchart showing the operation in the bath mist (silver ion mist on) mode.

  In step ST1, the operation is started when the silver ion mist is turned on and then the bath mist is turned on.

  Next, in step ST2, the heater unit 33 of the bathroom air conditioner 3 is energized, and the heater unit 33 is heated. Further, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is fully closed, that is, the circulation position (see FIG. 6A).

  In this case, since the circulation air path 43a from the suction port 38 to the blower outlet 41 is formed in the fan part 32, the air sucked from the suction port 38 passes through the circulation air path 43a and is warmed by the heater part 33. The air is blown into the bathroom 101 from the air outlet 41 through the air outlet grill 46 of the front panel 26.

  Next, in step ST3, the nozzle unit 2C is controlled and rotated so that the nozzle 2m faces the bathtub 101b. This prevents mist from being applied to the person's head.

  Next, wastewater treatment is performed in step ST4. In this case, in the solenoid valve unit 2A, the solenoid valve 2d (solenoid valve 1) and the solenoid valve 2f (solenoid valve 3) are opened (see FIG. 2). Hot water supplied from the heat pump hot water supply device 4 through the water supply pipe 2a is supplied to the drain pipe 2c via the electromagnetic valve 2d, the silver ion unit 2g, and the electromagnetic valve 2f (see FIGS. 1 and 2).

  Next, in step ST5, the silver ion unit 2g is energized, and silver ions are eluted from the silver ion unit 2g into warm water. In this case, the silver ion concentration is controlled to a high concentration, for example, 300 ppb, by controlling the value of the applied voltage or the ratio of the application time when the voltage is intermittently applied.

  As a result, the hot water supplied to the drain pipe 2c contains high-concentration silver ions, and the drain pipe 2c and the drain pan 101c are subjected to antibacterial activity, thereby effectively preventing the growth of fungi such as fungi. Is done.

  Next, in step ST6, based on the detection output of the temperature detection sensor 2h disposed in the electromagnetic valve unit 2A, the temperature of the hot water supplied to the electromagnetic valve unit 2A via the water supply pipe 2a is equal to or higher than a predetermined value. For example, it is determined whether or not the angle is 35 ° or more. After the temperature becomes equal to or higher than the predetermined value, the process proceeds to step ST7.

  In step ST7, mist generation processing is performed. As described above, by performing the mist generation process after the temperature of the hot water supplied to the electromagnetic valve unit 2A becomes equal to or higher than a predetermined value, a person existing in the bathroom 101 feels chills by the mist. Not to be.

  In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2f (electromagnetic valve 3) is closed and the electromagnetic valve 2e (electromagnetic valve 2) is opened (see FIG. 2). In this case, the hot water supplied from the heat pump hot water supply device 4 through the water supply pipe 2a is supplied to the nozzle pipe 2b via the electromagnetic valve 2d, the silver ion unit 2g, and the electromagnetic valve 2e (see FIGS. 1 and 2).

  In step ST8, the value of the applied voltage of the silver ion unit 2g is changed, and the concentration of silver ions eluted from the silver ion unit 2g into warm water is a concentration that does not affect the human body and has an antibacterial effect. Controlled to a low concentration, for example 100 ppb.

  Thereby, warm water is supplied from the nozzle pipe 2b to each nozzle 2m of the nozzle unit 2C and is ejected into the bathroom 101 as mist. And since this hot water contains silver ions, antibacterial action is carried out on the inner wall and floor surface of the bathroom 101 and further on the air passage of the bathroom air conditioner 3, and the propagation of fungi such as fungi in these is effective. To be prevented.

  Next, in step ST9, it is determined whether the bathing mist button 7b or 6b has been pressed to turn off the bathing mist, or whether the operation stop button 7d has been pressed to instruct a stop. When bathing mist is turned off or a stop is instructed, the process proceeds to step ST10. In step ST10, the operation of the bathroom air conditioner 3 is stopped. That is, energization to the heater unit 33 and the fan motor 36 of the bathroom air conditioner 3 is stopped.

  Next, in step ST11, the energization to the silver ion unit 2g is stopped, and the elution of silver ions from the silver ion unit 2g to the hot water is stopped. In step ST12, a water draining process is performed. In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2d (electromagnetic valve 1) is closed and the electromagnetic valve 2f (electromagnetic valve 3) is opened (see FIG. 2). As a result, the hot water remaining in the nozzle pipe 2b is supplied to the drain pipe 2c via the electromagnetic valves 2e and 2f (see FIGS. 1 and 2).

  Then, in step ST13, it is determined whether or not a predetermined time required for the water draining process, for example, 3 seconds has elapsed. When the predetermined time has elapsed, the process proceeds to step ST14. In step ST14, stop processing is performed. In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2e (electromagnetic valve 2) and the electromagnetic valve 2f (electromagnetic valve 3) are closed (see FIG. 2). At this time, the nozzle unit 2C is also controlled, and the direction of the nozzle 2m is returned to the original position.

  After this stop process, a series of operations in the bathing mist (silver ion mist on) mode is completed in step ST15.

<Other operation of bath mist (silver ion mist on) mode>
In the flowchart of FIG. 11, when the bath mist is turned off or a stop is instructed, the mist generating device 2 immediately drains water, but hot water containing high-concentration silver ions is removed. The drainage treatment may be performed after draining the drain pipe 2c.

  The flowchart of FIG. 12 is such that the drainage process is performed after the drainage process. In FIG. 12, steps corresponding to those in FIG. 11 are denoted by the same reference numerals, and detailed description thereof is omitted.

  After stopping operation | movement of the bathroom air conditioner 3 by step ST10, it progresses to step ST16. In step ST16, waste water treatment is performed. In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2e (electromagnetic valve 2) is closed and the electromagnetic valve 2f (electromagnetic valve 3) is opened (see FIG. 2). Hot water supplied from the heat pump hot water supply device 4 through the water supply pipe 2a is supplied to the drain pipe 2c via the electromagnetic valve 2d, the silver ion unit 2g, and the electromagnetic valve 2f (see FIGS. 1 and 2).

  Next, in step ST17, the value of the applied voltage of the silver ion unit 2g is changed, and the concentration of silver ions eluted from the silver ion unit 2g into warm water is again controlled to a high concentration, for example, 300 ppb. .

  As a result, the hot water supplied to the drain pipe 2c contains high-concentration silver ions, and the drain pipe 2c and the drain pan 101c are antibacterial again, so that fungi such as fungi can propagate effectively. Is prevented.

  Next, in step ST18, it is determined whether or not a predetermined time necessary for wastewater treatment for antibacterial, for example, 5 seconds has elapsed. When the predetermined time has elapsed, the process proceeds to step ST11, the generation of silver ions is stopped, and then the water draining process is performed in step ST12 ′.

  In this step ST12 ′, in the electromagnetic valve unit 2A, the electromagnetic valve 2d (electromagnetic valve 1) is closed and the electromagnetic valve 2e (electromagnetic valve 2) is opened, so that the electromagnetic valve control differs from step ST12 in the flowchart of FIG. As a result, both the solenoid valve 2e (solenoid valve 2) and the solenoid valve 2f (solenoid valve 3) are opened, and the hot water remaining in the nozzle pipe 2b causes the solenoid valves 2e and 2f to be opened. And supplied to the drain pipe 2c (see FIGS. 1 and 2).

<Operation of bathing mist mode>
When the bath mist button 7b is pressed by the mist remote controller 7 to turn on the bath mist, or when the bath mist button 6b is pressed by the air conditioning remote controller 6 to turn on the bath mist, the bath mist mode is entered and the operation of this mode is started. Is done.

  FIG. 13 is a flowchart showing the operation of this bathing mist mode.

  In step ST21, the operation is started by turning on the bath mist.

  Next, in step ST22, the heater 33 of the bathroom air conditioner 3 is energized, and the heater 33 is heated. Further, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is fully closed, that is, the circulation position (see FIG. 6A).

  In this case, since the circulation air path 43a from the suction port 38 to the blower outlet 41 is formed in the fan part 32, the air sucked from the suction port 38 passes through the circulation air path 43a and is warmed by the heater part 33. The air is blown into the bathroom 101 from the air outlet 41 through the air outlet grill 46 of the front panel 26.

  Next, in step ST23, the nozzle unit 2C is controlled and rotated so that the nozzle 2m faces toward the bathtub 101b. This prevents mist from being applied to the person's head.

  Next, wastewater treatment is performed in step ST24. In this case, in the solenoid valve unit 2A, the solenoid valve 2d (solenoid valve 1) and the solenoid valve 2f (solenoid valve 3) are opened (see FIG. 2). Hot water supplied from the heat pump hot water supply device 4 through the water supply pipe 2a is supplied to the drain pipe 2c via the electromagnetic valve 2d, the silver ion unit 2g, and the electromagnetic valve 2f (see FIGS. 1 and 2).

  Next, in step ST25, based on the detection output of the temperature detection sensor 2h disposed in the electromagnetic valve unit 2A, the temperature of the hot water supplied to the electromagnetic valve unit 2A via the water supply pipe 2a is equal to or higher than a predetermined value. For example, it is determined whether or not the angle is 35 ° or more. After the temperature becomes equal to or higher than the predetermined value, the process proceeds to step ST26.

  In step ST26, mist generation processing is performed. As described above, by performing the mist generation process after the temperature of the hot water supplied to the electromagnetic valve unit 2A becomes equal to or higher than a predetermined value, a person existing in the bathroom 101 feels chills by the mist. Not to be.

  In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2f (electromagnetic valve 3) is closed and the electromagnetic valve 2e (electromagnetic valve 2) is opened (see FIG. 2). In this case, the hot water supplied from the heat pump hot water supply device 4 through the water supply pipe 2a is supplied to the nozzle pipe 2b via the electromagnetic valve 2d, the silver ion unit 2g, and the electromagnetic valve 2e (see FIGS. 1 and 2). Thereby, warm water is supplied from the nozzle pipe 2b to each nozzle 2m of the nozzle unit 2C and is ejected into the bathroom 101 as mist.

  Next, in step ST27, it is determined whether or not the bath mist button 7b or 6b is pressed to turn off the bath mist, or the operation stop button 7d is pressed and a stop is instructed. When bathing mist is turned off or stop is instructed, the process proceeds to step ST28. In step ST28, the operation of the bathroom air conditioner 3 is stopped. That is, energization to the heater unit 33 and the fan motor 36 of the bathroom air conditioner 3 is stopped.

Next, a water draining process is performed in step ST29. In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2d (electromagnetic valve 1) is closed and the electromagnetic valve 2f (electromagnetic valve 3) is opened (see FIG. 2). Thereby, the hot water remaining in the nozzle pipe 2b is supplied to the drain pipe 2c via the electromagnetic valves 2e and 2f (see FIGS. 1 and 2).
Next, in step ST30, it is determined whether or not a predetermined time required for the water draining process, for example, 3 seconds has elapsed. When the predetermined time has elapsed, the process proceeds to step ST31. In step ST31, stop processing is performed. In this case, in the electromagnetic valve unit 2A, the electromagnetic valve 2e (electromagnetic valve 2) and the electromagnetic valve 2f (electromagnetic valve 3) are closed (see FIG. 2). At this time, the nozzle unit 2C is also controlled, and the direction of the nozzle 2m is returned to the original position.

  After this stop process, a series of operations in the bathing mist mode is completed in step ST32.

  In step ST23, the nozzle unit 2C is controlled so that the nozzle 2m is rotated toward the bathtub 101b. However, the bather is directly exposed to the mist so that the nozzle 2m is rotated toward the washing area 101e. May be. Furthermore, the bather may be able to select the bathtub 101b side and the washing area 101e side by an operation button (not shown).

<Operation of ventilation standard (silver ion mist on) mode>
When the silver ion mist button 6c is pushed by the air-conditioning remote control 6 to turn on the silver ion mist, and then the ventilation button 6g is pushed to turn on the ventilation standard, the ventilation standard (silver ion mist on) mode is set. The mode operation is started. This mode constitutes the first operation mode.

  FIG. 14 is a flowchart showing the operation in the ventilation standard (silver ion mist on) mode.

  In step ST41, the operation is started when the silver ion mist is turned on and then the ventilation standard is turned on.

  Next, in step ST42, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is fully opened, that is, the ventilation position (see FIG. 6B).

  In this case, since the ventilation air passage 43b from the suction port 38 to the exhaust port 42 is formed in the fan section 32, the air sucked from the suction port 38 passes through the ventilation air passage 43b and the exhaust port 42, and 1 is exhausted from the exhaust grill 8a to the outside through the exhaust duct 8 shown in FIG. 1 (ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted.

  Next, in step ST43, in the mist generating device 2, hot water from which silver ions have been eluted is supplied to each nozzle 2m of the nozzle unit 2C and is ejected into the bathroom 101 as mist. In this case, the silver ion concentration is a concentration that does not affect the human body by controlling the value of the applied voltage or the ratio of the application time when the voltage is applied intermittently, and a low concentration that has an antibacterial action, for example, Controlled to 100 ppb.

  The operation until the mist is ejected in step ST43 corresponds to the operation from step ST3 to step ST8 in the bathing mist mode shown in FIG. 11, for example.

  In this manner, mist containing silver ions is ejected into the bathroom 101 in a state where the ventilation operation is performed. In this case, since this mist passes through the ventilation air passage 43b and the exhaust port 42, and further exhausts from the exhaust grill 8a to the outside through the exhaust duct 8, antibacterial action of the ventilation path is performed. Bacteria growth is effectively prevented.

  Next, in step ST44, it is determined whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the process proceeds to step ST45. In step ST45, the mist ejection in the mist generator 2 is stopped. The operation until the mist ejection is stopped in step ST45 corresponds to, for example, the operation from step ST11 to step ST14 in the bathing mist mode shown in FIG.

  Next, in step ST46, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST47, the fan ventilation operation of the bathroom air conditioner 3 is stopped, and then, in step ST48, a series of operations in the ventilation standard (silver ion mist on) mode ends.

<Operation of ventilation standard mode>
When the ventilation button 6g is pressed by the air-conditioning remote controller 6 to turn on the ventilation standard, the ventilation standard mode is set and the operation of this mode is started.

  FIG. 15 is a flowchart showing the operation in the ventilation standard mode.

  In step ST51, the operation is started when the ventilation standard is turned on.

  Next, in step ST52, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is fully opened, that is, the ventilation position (see FIG. 6B).

  In this case, since the ventilation air passage 43b from the suction port 38 to the exhaust port 42 is formed in the fan section 32, the air sucked from the suction port 38 passes through the ventilation air passage 43b and the exhaust port 42, and 1 is exhausted from the exhaust grill 8a to the outside through the exhaust duct 8 shown in FIG. 1 (ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted.

  Next, in step ST53, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, the operation of the fan ventilation operation of the bathroom air conditioner 3 is stopped in step ST54, and thereafter, the series of operations in the ventilation standard mode ends in step ST55.

<Operation of bathroom drying (silver ion mist on) mode>
When the silver ion mist button 6c is pressed by the air-conditioning remote controller 6 to turn on the silver ion mist, and then the ventilation button 6g is pressed to turn on the bathroom drying, the bathroom drying (silver ion mist on) mode is set. The mode operation is started. This mode constitutes the fourth operation mode.

  FIG. 16 is a flowchart showing the operation in the bathroom drying (silver ion mist on) mode.

  In step ST61, the operation is started by turning on the silver ion mist and then turning on the bathroom drying.

  Next, in step ST62, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 6C).

  In this case, since both the circulation air passage 43a from the suction port 38 to the blowout port 41 and the ventilation air passage 43b from the suction port 38 to the exhaust port 42 are formed in the fan part 32, the air sucked from the suction port 38 Is partly blown into the bathroom 101 through the circulation air passage 43a from the air outlet 41 through the air outlet grill 46 of the front panel 26, and the other is passed through the ventilation air passage 43b and the exhaust port 42, as shown in FIG. Exhaust air is exhausted from the exhaust grill 8a through the exhaust duct 8 shown (circulation ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101.

  Next, in step ST63, in the mist generating device 2, hot water from which silver ions have been eluted is supplied to each nozzle 2m of the nozzle unit 2C and is ejected into the bathroom 101 as mist. In this case, the silver ion concentration is controlled to a high concentration, for example, 300 ppb, by controlling the value of the applied voltage or the ratio of the application time when the voltage is intermittently applied.

  The operation until the mist is ejected in step ST63 corresponds to, for example, the operations of steps ST5 and ST7 in the bathing mist mode shown in FIG.

  In this way, mist containing silver ions is ejected into the bathroom 101 while the circulation ventilation operation is performed. In this case, the mist causes antibacterial action on the inner wall and floor surface of the bathroom 101, and the growth of fungi such as fungi in these is effectively prevented.

  Next, in step ST64, it is determined whether or not the bathroom lighting switch 69B is turned on. In step ST65, it is determined whether or not a human body is detected by the human body detection sensor 69A. When the bathroom lighting switch 69B is not turned on and the human body is not detected by the human body detection sensor 69A, the process proceeds to step ST66.

  When the bathroom lighting switch 69B is turned on in step ST64, or when a human body is detected in step ST65, the process proceeds to step ST67. In this step ST67, the value of the applied voltage of the silver ion unit 2g is changed, and the concentration of silver ions eluted from the silver ion unit 2g into hot water is a concentration that does not affect the human body and has an antibacterial effect. The concentration is controlled, for example, 100 ppb.

  After step ST67, it is determined in step ST68 whether or not the bathroom lighting switch 69B is turned on. In step ST69, it is determined whether or not a human body is detected by the human body detection sensor 69A. If at least the bathroom lighting switch 69B is turned on or a human body is detected by the human body detection sensor 69A, the process returns to step ST68, and these determinations are repeated.

  However, when the bathroom lighting switch 69B is not turned on and a human body is not detected by the human body detection sensor 69A, the process returns to step ST63, and the value of the applied voltage of the silver ion unit 2g is changed. The concentration of silver ions eluted from the ion unit 2g into warm water is again controlled to a high concentration, for example, 300 ppb.

  As described above, when the bathroom lighting switch 69B is turned on and there is a possibility that there is a person in the bathroom 101, or when a human body is detected by the human body detection sensor 69A and there is a person in the bathroom 101, it is ejected as a mist. Since the concentration of silver ions in hot water is changed from 300 ppb to 100 ppb, it is possible to prevent the human body in the bathroom 101 from being affected, and the silver ion concentration remains high when there is no person in the bathroom 101. Therefore, the antibacterial action of the inner wall and floor surface of the bathroom 101 can be sufficiently enhanced.

  In step ST66, it is determined whether or not a predetermined time has elapsed. When the predetermined time has not elapsed, the process returns to step ST64, and when the predetermined period has elapsed, the process proceeds to step ST70. In step ST70, the mist ejection in the mist generating device 2 is stopped. The operation until the mist ejection is stopped in step ST70 corresponds to, for example, the operation from step ST11 to step ST14 in the bathing mist mode shown in FIG.

  Next, in step ST71, the bathroom air conditioner 3 performs the circulation ventilation operation, and the above-described positive ions and negative ions are generated from the ion generator 44. Thus, since positive ions and negative ions are released into the bathroom 101 in a state where the circulation ventilation operation is performed, the effect of suppressing the generation of mold on the inner wall and floor surface of the bathroom 101 is increased. .

  Next, in step ST72, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST73, the circulation ventilation operation and ion generation operation of the bathroom air conditioner 3 are stopped, and thereafter, in step ST74, a series of operations in the bathroom drying (silver ion mist on) mode is performed. finish.

  Note that human detection by the human detection means is performed using both the bathroom lighting switch 69 in step ST68 and the human body detection sensor 69A in step ST69, but only one of the bathroom lighting switch 69 and the human body detection sensor 69A is used. May be used. The person detecting means may be a door opening / closing sensor for detecting the opening / closing of a bathroom door, as long as it can directly or indirectly detect the presence of a person, such as a bathroom lighting switch 69 or a human body detection sensor 69A. It is not limited to.

  Moreover, although the damper 40 was set as the circulation ventilation position (refer FIG. 6C) by step ST71 and step ST62, it is good also considering only step ST71 as a circulation position (refer FIG. 6A). Further, without providing step ST62, the mist containing silver ions may be ejected from the mist generating device 2 in step ST63 without driving the fan unit 32 of the bathroom air conditioner 3.

<Operation in bathroom drying mode>
When the ventilation button 6g is pressed by the air-conditioning remote controller 6 and the bathroom drying is turned on, the bathroom drying mode is set, and the operation of this mode is started.

  FIG. 17 is a flowchart showing the operation in the bathroom drying mode.

  In step ST81, the operation starts when the bathroom drying is turned on.

  Next, in step ST82, the fan motor 36 of the bathroom air conditioner 3 is energized, and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 6C).

  In this case, since both the circulation air passage 43a from the suction port 38 to the blowout port 41 and the ventilation air passage 43b from the suction port 38 to the exhaust port 42 are formed in the fan part 32, the air sucked from the suction port 38 Is partly blown into the bathroom 101 through the circulation air passage 43a from the air outlet 41 through the air outlet grill 46 of the front panel 26, and the other is passed through the ventilation air passage 43b and the exhaust port 42, as shown in FIG. Exhaust air is exhausted from the exhaust grill 8a through the exhaust duct 8 shown (circulation ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101.

  In step ST82, the ion generator 44 generates the aforementioned positive ions and negative ions. Thus, since positive ions and negative ions are released into the bathroom 101 in a state where the circulation ventilation operation is performed, generation of mold on the inner wall and floor surface of the bathroom 101 can be suppressed.

  Next, in step ST83, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST84, the circulation ventilation operation and the ion generation operation of the bathroom air conditioner 3 are stopped, and then, in step ST85, a series of operations in the bathroom drying mode ends.

<Operation in heating mode>
When the heating button 6f is pressed by the air-conditioning remote controller 6 to turn on the heating, the heating mode is set, and the operation of this mode is started.

  FIG. 18 is a flowchart showing the operation in the heating mode.

  In step ST91, the operation is started by turning on the heating.

  Next, in step ST92, the heater unit 33 of the bathroom air conditioner 3 is energized, and the heater unit 33 is heated. Further, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is fully closed, that is, the circulation position (see FIG. 6A).

  In this case, since the circulation air path 43a from the suction port 38 to the blower outlet 41 is formed in the fan part 32, the air sucked from the suction port 38 passes through the circulation air path 43a and is warmed by the heater part 33. Then, the air is blown out from the air outlet 41 into the bathroom 101 through the air outlet grill 46 of the front panel 26 (circulation operation). Thereby, the inside of the bathroom 101 is warmed.

  Next, in step ST93, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, the operation of the bathroom air conditioner 3 is stopped in step ST94. That is, energization to the heater unit 33 and the fan motor 36 of the bathroom air conditioner 3 is stopped. Thereafter, in step ST95, a series of operations in the heating mode ends.

  Although detailed explanation is omitted, when the heating is turned on after the silver ion mist is turned on, silver ions are contained in the bathroom 101 as in the above-described ventilation standard (silver ion mist on) mode. You may make it the mist by warm water spout. Thereby, the antibacterial effect in the bathroom 101 is acquired.

<Operation in cool breeze (silver ion mist on) mode>
When the air-conditioning remote controller 6 is pressed to turn on the silver ion mist button 6c to turn on the silver ion mist, and then the cool wind button 6e is pressed to turn on the cool wind, the cool wind (silver ion mist on) mode is set. Operation starts. This mode constitutes the second operation mode.

  FIG. 19 is a flowchart showing the operation in the cool breeze (silver ion mist on) mode.

  In step ST101, the operation is started by turning on the silver ion mist and then turning on the cool air.

  Next, in step ST102, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 6C).

  In this case, since both the circulation air passage 43a from the suction port 38 to the blowout port 41 and the ventilation air passage 43b from the suction port 38 to the exhaust port 42 are formed in the fan part 32, the air sucked from the suction port 38 Is partly blown into the bathroom 101 through the circulation air passage 43a from the air outlet 41 through the air outlet grill 46 of the front panel 26, and the other is passed through the ventilation air passage 43b and the exhaust port 42, as shown in FIG. Exhaust air is exhausted from the exhaust grill 8a through the exhaust duct 8 shown (circulation ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101.

  Next, in step ST103, in the mist generating device 2, hot water from which silver ions have been eluted is supplied to each nozzle 2m of the nozzle unit 2C, and is ejected into the bathroom 101 as mist. In this case, the silver ion concentration is a concentration that does not affect the human body by controlling the value of the applied voltage or the ratio of the application time when the voltage is applied intermittently, and a low concentration that has an antibacterial action, for example, Controlled to 100 ppb.

  The operation until the mist is ejected in step ST43 corresponds to the operation from step ST3 to step ST8 in the bathing mist mode shown in FIG. 11, for example.

  In this way, mist containing silver ions is ejected into the bathroom 101 while the circulation ventilation operation is performed. In this case, since this mist passes through the circulation air passage 43a and the ventilation air passage 43b, antibacterial action of these air passages is performed.

  Next, in step ST104, it is determined whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the process proceeds to step ST105. In step ST105, the mist ejection in the mist generator 2 is stopped. The operation until the mist ejection is stopped in step ST105 corresponds to, for example, the operation from step ST11 to step ST14 in the bathing mist mode shown in FIG.

  Next, in step ST106, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST107, the operation of the circulation ventilation operation of the bathroom air conditioner 3 is stopped, and then, in step ST108, a series of operations in the cool breeze (silver ion mist on) mode ends.

  In addition, although the damper 40 was made into the circulation ventilation position (refer FIG. 6C) by step ST102, it is good also as a circulation position (refer FIG. 6A). Furthermore, the fan circulation ventilation operation or the fan circulation operation may be performed after the mist spraying stop in step ST105 or during the mist spraying without driving the fan unit 32 of the bathroom air conditioner 3.

<Operation in cool breeze mode>
When the cool breeze button 6e is pressed by the air conditioner remote controller 6 to turn on the cool breeze, the cool breeze mode is set and the operation of this mode is started.

  FIG. 20 is a flowchart showing the operation in the cool breeze mode.

  In step ST111, the operation is started by turning on silver ion mist and then turning on cool air.

  Next, in step ST112, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 6C).

  In this case, since both the circulation air passage 43a from the suction port 38 to the blowout port 41 and the ventilation air passage 43b from the suction port 38 to the exhaust port 42 are formed in the fan part 32, the air sucked from the suction port 38 Is partly blown into the bathroom 101 through the circulation air passage 43a from the air outlet 41 through the air outlet grill 46 of the front panel 26, and the other is passed through the ventilation air passage 43b and the exhaust port 42, as shown in FIG. Exhaust air is exhausted from the exhaust grill 8a through the exhaust duct 8 shown (circulation ventilation operation). Thereby, steam and moisture in the bathroom 101 are exhausted while circulating the air in the bathroom 101.

  Next, in step ST113, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST114, the operation of the circulation ventilation operation of the bathroom air conditioner 3 is stopped, and then, in step ST115, the series of operations in the cool air mode ends.

<Operation of clothes drying (silver ion mist on) mode>
When the air-conditioning remote controller 6 is pressed to turn on the silver ion mist button 6c to turn on the silver ion mist, and then the clothes drying button 6d is pressed to turn on the clothes drying, the clothes drying (silver ion mist on) mode is set. This mode of operation is started. This mode constitutes the third operation mode.

  FIG. 21 is a flowchart showing the operation in the clothes drying (silver ion mist on) mode.

  In step ST121, the operation is started when the silver ion mist is turned on and then the clothes drying is turned on.

  Next, in step ST122, the heater unit 33 of the bathroom air conditioner 3 is energized, and the heater unit 33 is heated. Further, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 6C).

  In this case, in the fan part 32, both the circulation air path 43a from the suction port 38 to the blower outlet 41 and the ventilation air path 43b from the suction port 38 to the exhaust port 42 are formed. A part of the air sucked from the suction port 38 passes through the circulation air passage 43a, is heated by the heater 33, and blown out from the blower outlet 41 into the bathroom 101 through the blowout grill 46 of the front panel 26. Passes through the ventilation air passage 43b and the exhaust port 42, and is further exhausted from the exhaust grill 8a to the outside through the exhaust duct 8 shown in FIG. 1 (circulation ventilation operation). As a result, while the air in the bathroom 101 is circulated, the moisture in the bathroom 101 is exhausted, and the clothes are dried.

  Next, in step ST123, in the mist generating device 2, hot water from which silver ions are eluted is supplied to each nozzle 2m of the nozzle unit 2C, and is ejected into the bathroom 101 as mist. In this case, the silver ion concentration is controlled to a high concentration, for example, 300 ppb, by controlling the value of the applied voltage or the ratio of the application time when the voltage is intermittently applied. In this case, the rotation control of the nozzle unit 2C is performed so that the nozzle 2m faces the clothing so that the mist is applied to the clothing.

  The operation until the mist is ejected in step ST43 corresponds to, for example, the operations of steps ST5 and ST7 in the bathing mist mode shown in FIG.

  Thus, the mist containing silver ions is ejected into the bathroom 101 in a state where the heater is on and the circulation ventilation operation is performed. Thereby, the mist containing silver ions is applied to the clothing, so that the clothing is sterilized and the generation of odor during clothing is suppressed.

  Next, in step ST124, it is determined whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the process proceeds to step ST125. In this step ST125, the mist ejection in the mist generator 2 is stopped. The operation until the mist ejection is stopped in step ST125 corresponds to the operation from step ST11 to step ST14 in the bathing mist mode shown in FIG. 11, for example.

  Next, in step ST126, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST127, the operation of the circulation ventilation operation of the bathroom air conditioner 3 is stopped, and then, in step ST128, the series of operations in the clothes drying (silver ion mist on) mode is completed.

  In addition, although the damper 40 was made into the circulation ventilation position (refer FIG. 6C) by step ST122, it is good also as a circulation position (refer FIG. 6A). Further, the fan circulation ventilation operation or the fan circulation operation may be performed after the mist spraying stop in step ST125 or during the mist spraying without driving the fan unit 32 of the bathroom air conditioner 3.

<Operation in clothes drying mode>
When the clothes drying button 6d is pressed by the air-conditioning remote controller 6 and the clothes drying is turned on, the clothes drying mode is set, and the operation in this mode is started.

  FIG. 22 is a flowchart showing the operation in the clothes drying mode.

  In step ST131, the operation starts when the clothes drying is turned on.

  Next, in step ST132, the heater unit 33 of the bathroom air conditioner 3 is energized, and the heater unit 33 is heated. Further, the fan motor 36 of the bathroom air conditioner 3 is energized and the fan 35 is rotated. In this case, the damper 40 is set to an intermediate position between the circulation position and the ventilation position, that is, the circulation ventilation position (see FIG. 6C).

  In this case, in the fan part 32, both the circulation air path 43a from the suction port 38 to the blower outlet 41 and the ventilation air path 43b from the suction port 38 to the exhaust port 42 are formed. A part of the air sucked from the suction port 38 passes through the circulation air passage 43a, is heated by the heater 33, and blown out from the blower outlet 41 into the bathroom 101 through the blowout grill 46 of the front panel 26. Passes through the ventilation air passage 43b and the exhaust port 42, and is further exhausted from the exhaust grill 8a to the outside through the exhaust duct 8 shown in FIG. 1 (circulation ventilation operation). As a result, while the air in the bathroom 101 is circulated, the moisture in the bathroom 101 is exhausted, and the clothes are dried.

  Next, in step ST133, it is determined whether the timer set time has elapsed. This timer setting time can be arbitrarily set by the user using, for example, the up / down key 6j of the air-conditioning remote controller 6. When the set time has elapsed, in step ST134, the operation of the circulation ventilation operation of the bathroom air conditioner 3 is stopped, and then, in step ST135, the series of operations in the clothes drying mode is completed.

<Notification of replacement time of silver ion unit>
As described above, the light emitting element 7e and the buzzer 7f of the mist remote controller 7 and the light emitting element 6h of the air conditioning remote controller 6 notify the user of the replacement time of the silver ion unit 2g arranged in the electromagnetic valve unit 2A. The control unit 5A of the bathroom air conditioner 3 to which the air conditioner remote controller 6 is connected and the power supply unit 2B to which the mist remote controller 7 is connected are connected. For example, in the control unit 5A of the bathroom air conditioner 3, the accumulated operation time from when the silver ion unit 2g is attached is managed. The control unit 5A always determines whether or not the operation accumulated time has reached a predetermined time corresponding to the replacement time, and determines that it is the replacement time when the operation accumulated time exceeds the predetermined time.

  Thus, when it is determined by the control unit 5A that it is time to replace, the light-emitting element 7e of the mist remote controller 7 and the light-emitting element 6h of the air-conditioning remote controller 6 are in a continuous light emission state or a flashing light emission state under the control of the control unit 5A. Also, the buzzer 7f of the mist remote controller 7 is an operation mode for eluting silver ions from the silver ion unit 2g into warm water or water, for example, bathing mist (silver ion mist on) mode, ventilation standard (silver ion mist on) mode, bathroom drying ( A buzzer sound is output when any one of the silver ion mist on) mode, the cool breeze (silver ion mist on) mode, and the clothes drying (silver ion mist on) mode is selected.

  In addition, although different from the above-described embodiment, it is determined whether or not the replacement time has been reached based on the number of ejection operations of mist (silver ion mist) containing metal ions such as silver ions from the mist generating device 2 ( Determination). The number of silver ion mist ejection operations may be the number of times that the silver ion mist buttons 6c and 7c are pressed and the operation mode in which silver ions are eluted is executed, or the number of times that a drive voltage is applied to the silver ion unit 2g. Other methods may be used.

<Main effects of the embodiment>
As described above, according to the bathroom system 1 shown in FIG. 1, the hot water discharged from the heat pump hot water supply device 4 is supplied to the electromagnetic valve unit 2A via the water supply pipe 2a. Then, silver ions having an antibacterial action are eluted in the hot water by the silver ion unit 2g disposed in the electromagnetic valve unit 2A. Therefore, the mist ejected from each nozzle 2m of the nozzle unit 2C contains silver ions, and although the mist which is warm water is ejected into the bathroom 101, the antibacterial of the inner wall and floor surface of the bathroom 101 is discharged. And the growth of mold fungi can be well prevented.

  Further, according to the bathroom system 1 shown in FIG. 1, when mist containing silver ions is ejected from each nozzle 2m of the nozzle unit 2C, hot water having a silver ion concentration of, for example, 300 ppb before and after mist ejection. Is allowed to flow through the drain pipe 2c, so that the drain pipe 2c and the drain pan 101c can be antibacterial, and the growth of fungi can be suppressed.

  Further, according to the bathroom system 1 shown in FIG. 1, when the bathroom air conditioner 3 is operated in the ventilation standard (silver ion mist on) mode, the ventilation operation is performed in cooperation with the mist generator 2. A mist containing silver ions in the bathroom 101 is ejected for a predetermined time, and the antibacterial of the ventilation air passage 43b can be performed by the silver ions, effectively preventing the growth of fungi such as fungi. it can.

  In addition, according to the bathroom system 1 shown in FIG. 1, when the bathroom air conditioner 3 is operated in the bathroom drying (silver ion mist on) mode, the circulation ventilation operation is performed in cooperation with the mist generator 2. Thus, the mist containing silver ions in the bathroom 101 is ejected for a predetermined time, and the inner wall and floor surface of the bathroom 101 can be antibacterized by the silver ions. The propagation of such bacteria can be effectively prevented.

  Further, according to the bathroom system 1 shown in FIG. 1, when the bathroom air conditioner 3 is operated in a cool breeze (silver ion mist on) mode, the circulation ventilation operation is performed in cooperation with the mist generator 2. In the bathroom 101, mist containing silver ions is ejected for a predetermined time. Since the mist containing silver ions passes through the circulation air passage 43a and the ventilation air passage 43b, the antibacterial effect of these air passages is effective. Can be done automatically.

  Further, according to the bathroom system 1 shown in FIG. 1, when the bathroom air conditioner 3 is operated in the clothes drying (silver ion mist on) mode, the heater is turned on and the circulation ventilation operation is performed in cooperation with the mist generating device 2. The mist containing silver ions in the bathroom 101 is ejected for a predetermined time in the bathroom 101, and the clothing contains mist containing silver ions. And the generation of odor during clothing can be suppressed.

  In addition, according to the bathroom system 1 shown in FIG. 1, when the bathroom air conditioner 3 is operated in the bathroom drying (silver ion mist on) mode, the circulation ventilation operation is performed in cooperation with the mist generator 2. The mist containing silver ions in the bathroom 101 is ejected for a predetermined time. When the bathroom lighting switch 69B is turned on and there is a possibility that there is a person in the bathroom 101, or the human body detection sensor 69A. When the human body is detected and there is a person in the bathroom 101, the concentration of silver ions in the hot water ejected as mist is changed from 300 ppb to 100 ppb, thereby preventing the human body in the bathroom 101 from being affected. In addition, when there is no person in the bathroom 101, the antibacterial action of the inner wall and floor of the bathroom 101 can be sufficiently enhanced.

  Further, according to the bathroom system 1 shown in FIG. 1, the replacement time of the silver ion unit 2g arranged in the electromagnetic valve unit 2A is changed according to the light emitting element 7e and buzzer 7f of the mist remote controller 7 and the light emitting element 6h of the air conditioning remote controller 6. Therefore, the user can easily know the replacement time of the silver ion unit 2g.

  Further, according to the bathroom system 1 shown in FIG. 1, the electromagnetic valve unit 2A is disposed in the vicinity of the inspection port 101a provided on the ceiling of the bathroom 101, and the silver disposed in the electromagnetic valve unit 2A. The ion unit 2g can be easily replaced, and maintenance is facilitated.

<Modification>
In the above-described embodiment, the flow path switching device is configured by the electromagnetic valve unit 2A (see FIG. 2), but detailed description is omitted, but other configurations, for example, configurations using a three-way electromagnetic valve or the like. Can also be adopted.

  In the above-described embodiment, the electromagnetic valve unit 2A is configured as shown in FIG. 2, and the silver ion unit 2g is attached in the electromagnetic valve unit 2A. However, as shown in FIG. 23, it is conceivable to attach the silver ion unit 2g to the outside of the electromagnetic valve unit 2Aa. In FIG. 23, parts corresponding to those in FIG.

  The solenoid valve unit 2Aa has the same configuration as that obtained by removing the silver ion unit 2g from the solenoid valve unit 2A. In this case, the silver ion unit 2g is attached to the nozzle pipe 2b connected to the connecting portion 2b ′. In this case, the silver ions can be eluted only in the hot water flowing through the nozzle pipe 2b, and the antibacterial effect by the mist ejected from each nozzle 2m of the nozzle unit 2C can be obtained when the electromagnetic valve unit 2A of FIG. 2 is used. The same. Although not connected here, if the silver ion unit 2g is connected to the connecting portion 2c ′, the antibacterial effect of the drain pipe 2c and the drain pan 101 can be obtained.

  In the above-described embodiment, the silver ion unit 2g is attached to the electromagnetic valve unit 2A, but it is also conceivable to attach this silver ion unit 2g to the hot water heater side. The silver ion unit 2g is attached in the vicinity of the hot water supply mixing valve 64 of the hot water supply pipe 65, for example, as shown in FIG. 24, parts corresponding to those in FIG. 7 are denoted by the same reference numerals and detailed description thereof is omitted.

  In this case, hot water in which silver ions are eluted can be supplied to all of the bathroom 101, the bathroom changing room 102, the kitchen 103, etc., to which hot water is supplied from the heat pump water heater 51A, and when this hot water is used, the antibacterial effect is caused by the silver ions. You will be able to get

  In the above-described embodiment, the hot water containing silver ions is ejected as mist from the nozzle 2m of the nozzle unit 2C. However, the hot water containing silver ions is used as a shower from the shower head. You may make it eject. By this shower, the wall surface and floor surface of the bathroom 101 can be antibacterial.

  In the above-described embodiment, silver ions are used as metal ions having antibacterial action, but other metal ions such as copper ions and zinc ions may be used.

  Moreover, in the above-described embodiment, the metal ions having antibacterial action, for example, silver ions, are eluted from the hot water. However, acidic electrolyzed water is generated from the hot water, and this acidic electrolyzed water is ejected from the nozzle 2m as a mist. You may make it make it.

  FIG. 25 shows the electrolyzed water generating unit 2D connected to the connecting portion 2b ′ of the electromagnetic valve unit 2Aa. In this electrolyzed water generating unit 2D, acidic electrolyzed water and alkaline electrolyzed water are generated according to the following principle. That is, a diaphragm is placed between two electrodes (anode and cathode) in an electrolytic cell, and an electrolysis auxiliary (NaCl) added to warm water (water) is flowed into the electrolytic cell for electrolysis. Thereby, acidic electrolyzed water is produced on the anode side and alkaline electrolyzed water is produced on the cathode side (diaphragm electrolysis).

  Chlorine gas is dissolved in the acidic electrolyzed water, and antibacterial action against microorganisms is obtained by the action of hypochlorous acid (HClO) generated from this chlorine gas. On the other hand, alkaline electrolyzed water produces sodium hydroxide (NaOH) that has a cleaning effect on protein-based and lipid-based soils.

  Here, the water supply pipe 71 of the electrolyzed water generating unit 2D is connected to the connecting portion 2b 'of the electromagnetic valve unit 2Aa, and hot water (water) is supplied to the electrolyzed water generating unit 2D via the electromagnetic valve 2C. Further, the acidic electrolyzed water drain pipe 72 of the electrolyzed water generating unit 2D is connected as a nozzle pipe to the connecting portion 2n of the nozzle unit 2C. Thereby, acidic electrolyzed water is ejected as mist, for example in the bathroom 101, from each nozzle 2m of the nozzle unit 2C. Further, the alkaline electrolyzed water drain pipe 73 of the electrolyzed water generating unit 2D is connected to the drain pipe 2c (not shown), and the alkaline electrolyzed water is discharged to the drain pan 101c through the drain pipe 2c.

  The pH of the acidic electrolyzed water generated by the electrolyzed water generating unit 2D is adjusted by adjusting the flow rate of warm water (water) supplied to the electrolyzed water generating unit 2D or the value of the voltage applied between the electrodes. Can be adjusted (see, for example, JP-A-6-246268).

  The following effects can be obtained by using this electrolytic generation unit 2D. For example, when slightly acidic electrolyzed water (about pH 6) is ejected as a mist from the nozzle 2m, the skin can be protected from various bacteria by bathing it in human skin. Moreover, when strong acidic electrolyzed water (about pH 2-3) is ejected as mist from the nozzle 2m, a strong antibacterial effect can be obtained. Further, by flowing alkaline electrolyzed water through the drain pipe 2c, the drain pipe 2c, the drain pan 101c, the drain port, and the like can be removed.

  Although it is conceivable to install the electrolyzed water generating unit 2D in the electromagnetic valve unit 2Aa, it is not preferable in terms of durability to pass the acidic electrolyzed water through the electromagnetic valve. Therefore, as shown in FIG. It is supposed to be attached to the outside of the electromagnetic valve unit 2Aa.
