Description

The present invention relates to a bathroom system for disinfecting a bathroom.

Users are highly dissatisfied with the bacteria and mold stains in the bathroom. In order to suppress this, for example, as described in Patent Document 1, a mist of electrolyzed water (sterilized water) is sprayed into the bathroom from an electrolyzed water spraying device attached to the ceiling of the bathroom. A bathroom ventilation fan is known that disinfects the bathroom and then ventilates it.

In addition, as described in Patent Document 2, electrolyzed water is sprayed from an electrolyzed water spray unit attached to the ceiling of the bathroom, causing stains such as slime caused by yeast bacteria etc. that grow on the bathroom floor. A bathroom heating/ventilating fan is known that effectively suppresses the growth of yeast and the like in the bathroom by performing a drying operation and a blowing operation after that.

Japanese Patent Application Publication No. 2006-292183 JP2019-165831A

In the devices described in Patent Documents 1 and 2, which are the prior art described above, electrolyzed water (sterilized water) is sprinkled from the ceiling of the bathroom, so the electrolyzed water accumulates on visible areas and targets for sterilization. It cannot be applied to the back side or gaps of objects.

Therefore, in conventional devices, it is possible to use a ventilation fan to circulate the air in the bathroom after spraying electrolyzed water to make the electrolyzed water work, but if the mist of sprayed electrolyzed water has a fine particle size, As the electrolyzed water evaporates, the concentration of the active ingredients in the electrolyzed water decreases, and by the time it reaches the back surface or crevice of the object to be sterilized, the sterilizing effect is lost. Furthermore, the mist of electrolyzed water adheres to various parts of the bathroom, resulting in water stains and deteriorating the appearance.

In order to solve the problems in the prior art described above, the inventors of the present invention have conducted extensive research, and have taken into consideration the conventional methods of spraying distance of sterilizing water, concentration of water landing, amount of water landing, etc. This technology has been developed further by dissolving the active ingredients of the sterilizing water vaporized after spraying, which are not used for sterilization in the conventional technology, into the remaining water in the bathroom. It was discovered that the disinfectant can be applied to every corner of the bathroom to sterilize a wider area within the bathroom.

The present invention was made in order to solve the problems of the prior art, and provides a bathroom system that can efficiently sterilize the bathroom by distributing the active ingredients of vaporized sterilizing water throughout the bathroom. is intended to provide.

In order to solve the above-mentioned problems, the present invention provides a bathroom system that disinfects the inside of a bathroom, and includes a sterilizing water device that includes a sterilizing water spouting part that sprays sterilizing water into the bathroom. , a ventilation/circulation device that performs a ventilation operation to exhaust the air in the bathroom to the outside, a ventilation/circulation device that performs a circulation operation to circulate the air in the bathroom, and a control unit that controls the sterilized water device and the ventilation/circulation device. The control unit controls the ventilation/circulation device and the sterilized water device to discharge sterilized water while circulating air, and starts discharging sterilized water while circulating air and then starts discharging sterilized water. The period from the end of sterilizing water spouting is called the sterilizing water spouting process, and the period from the end of sterilizing water spouting to the end of air circulation with air being circulated is the sterilizing water non-spraying process. step, and the control unit controls the ventilation/circulation device and the sterilization water device so that the time of the sterilization water spouting step is longer than the time of the sterilization water non-spouting step; controls the sterilizing water device to intermittently spout sterilizing water during the sterilizing water spouting period.
According to the present invention configured in this way, the control unit controls the ventilation/circulation device and the sterilized water device so that the length of the sterilized water spouting step is longer than the length of the sterilized water non-spouting step. Since the control is performed, the active ingredients remaining in the bathroom after spraying the sterilizing water can be thoroughly distributed in the bathroom, and the active ingredients of the sterilizing water can be spread throughout the bathroom. On the other hand, the applicant has obtained new knowledge that even if spraying of disinfectant water is continued for a long time, the concentration of disinfectant water in the bathroom becomes saturated. Therefore, in the present invention, the control unit is further configured to control the sterilizing water spouting section of the sterilizing water device to intermittently spout sterilizing water during the sterilizing water spouting step. did. This makes it possible to prevent the continuous application of an unnecessarily large amount of sterilizing water, while effectively distributing the active ingredients of the sterilizing water throughout the bathroom.

In the present invention, preferably, the control unit operates the sterilizing water device so that the length of time between the spouting intervals of the sterilizing water that is intermittently spouted is shorter than the time of the sterilizing water non-discharging step. Control.
In the present invention configured in this way, the control unit controls the removal so that the length of time between spouting of the sterilizing water that is intermittently spouted is shorter than the time of the sterilizing water non-spraying process. Since the sterilizing water device is controlled, the interval between spouting sterilizing water, which is performed multiple times intermittently, does not take that long, and there is enough time for the sterilizing water to finally be distributed throughout the bathroom. This allows the disinfectant water to work more effectively in the bathroom.

In the present invention, preferably, the control unit controls the ventilation/circulation device to circulate the air in the bathroom after the sterilized water device discharges the sterilized water, and then to ventilate the bathroom. control.
In the present invention configured in this way, the control unit is configured to circulate the air in the bathroom after the sterilized water device discharges sterilized water, and then to ventilate the bathroom. Since the ventilation and circulation equipment is controlled, it is possible to prevent humidity from rising due to residual disinfectant water in the bathroom and to suppress mold stains.

According to the bathroom system of the present invention, the active ingredients of the vaporized sterilizing water can be distributed throughout the bathroom, making it possible to efficiently sterilize the bathroom.

Temporal changes in the spatial concentration of sterilized water in the bathroom between the ON time and the OFF time of sterilized water when sterilized water is continuously spouted by the bathroom system according to the embodiment of the present invention FIG.

First, the basic principle of a bathroom system according to an embodiment of the present invention will be explained with reference to FIG. FIG. 1 is a diagram for explaining the basic principle of a bathroom system according to an embodiment of the present invention.
As shown in Figure 1, conventionally, sterilizing water with free chlorine concentration A is spouted from a nozzle, and when the sterilizing water reaches the target point to sterilize, it reaches the "effective concentration B". In addition, the "amount of water landing" and "action time" at the point where the sterilizing water reaches are also important.

This conventional technique has a problem in that the sterilizing water sprayed from the nozzle evaporates (vaporizes) before reaching the destination, resulting in a decrease in the concentration of the sterilizing water. Therefore, it was necessary to spray sterilized water by taking into account the concentration x amount of water landing x duration of action at the arrival point, making it difficult to sterilize a large area of the bathroom.

Here, the active ingredients of the sterilizing water that have been volatilized (vaporized) are not utilized for sterilization work until the sterilizing water reaches the destination from the nozzle. We have discovered that the active ingredients of (vaporized) sterilizing water can be used for sterilizing work. That is, first, the bathroom is closed, and in this state, the volatilized (vaporized) sterilizing water is dissolved in the residual water remaining on the bathroom washing area floor, bathtub apron, behind the counter, walls, etc., and thereby, This makes it possible to efficiently sterilize the bathroom by distributing the active ingredients of the vaporized sterilizing water throughout the bathroom.

Next, a bathroom in which a bathroom system according to an embodiment of the present invention is used will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view showing a bathroom in which a bathroom system according to an embodiment of the present invention is used, and FIG. 3 is an enlarged perspective view of the vicinity of the counter in FIG. 2.
As shown in FIG. 2, the bathroom 1 includes a first wall 2, a second wall 4, a third wall 6, and a fourth wall 8, which form four sides of a substantially rectangular parallelepiped. A bathtub 10 is provided on the second wall 4 side, and a washing area floor 12 is provided below between the fourth wall 8 and the bathtub 10. A drain port 14 is provided near the bathtub 10 on the floor 12 of this washing area, and hot water is discharged from the drain port 14 to the outside.

A counter 16 is provided on a part of the third wall 6 side. Above the counter 16 on the third wall 6, a mirror, a water tap, a shower hose, etc. are provided. A water discharging device 22 for discharging sterilized water and tap water (water), which constitutes a part of the bathroom system 20 according to the present embodiment, is provided on the lower surface side of the counter 16.

A ceiling 24 is attached to the upper ends of the first wall 2 to the fourth wall 8 described above, and a bathroom is provided on the ceiling 24 for ventilating and drying the air in the bathroom 1 that constitutes a part of the bathroom system 20. A drying device 26 is provided. As will be described later, this bathroom drying device 26 is for ventilating and circulating the air in the bathroom, and is also a device for vaporizing the sterilized water discharged by circulating the air. This corresponds to "ventilation/circulation equipment" and/or "circulation equipment."
Further, outside the bathroom 1, an operation panel 28 for operating the bathroom system 20 and a control device 30 for controlling the operations of the water discharging device 22 and the bathroom drying device 26 described above are provided.

As a modification, the operation panel 28 may be formed as an operation screen displayed on the screen of an electronic device such as a smartphone or a remote control. That is, the operation panel 28 may form an operation section that receives operation input from the user using operation buttons on such an operation screen. At this time, an operation panel 28 of an electronic device such as a smartphone or a remote control is electrically connected to the control unit 30 by wireless communication such as the Internet or infrared communication.
In addition, as another modification, the operation panel 28 may include a voice operation section that receives operation input from the user through voice input, or a voice operation section that accepts operation input from the user through gesture operation input using the user's fingers or the like (for example, when using It may be a gesture operation unit (such as a gesture operation unit that detects the user's hand or the like by holding the user's finger or the like over a predetermined space for a certain period of time, detects it as an operation input, and accepts the operation input, etc.).

As shown in FIG. 3, the counter 16 has a top plate 16a and a lower cover 16b, and is spaced upward from the washing area floor 12.

Next, the water discharging device 22 will be explained with reference to FIGS. 4 to 8. 4 is a partial sectional view of the water discharging device taken along the line IV-IV in FIG. 2, FIG. 5 is a front view showing the nozzle part of the water discharging device, and FIG. FIG. 7 is a perspective view showing how sterilizing water is being sprayed from the sterilizing water nozzle opening of the nozzle part of the water discharging device, and FIG. 8 is a sectional view of the nozzle part of the water discharging device. It is a perspective view showing a state where tap water is being sprinkled from a nozzle opening for retained water.

As shown in FIG. 4, a water spouting device 22 is provided inside the counter 16 (between the top plate 16a and the lower cover 16b), and this water spouting device 22 protrudes downward from the lower cover 16b of the counter 16. A nozzle section 32 is provided.
As also shown in FIG. 3, the nozzle part 32 is arranged at the lower part of the counter 16 at a position spaced apart from the washing area floor 12, and furthermore, the nozzle part 32 is arranged near the horizontal center of the counter 16, that is, the washing area floor. It is provided near the center in the horizontal direction of 12.

Returning to FIG. 4, the water discharging device 22 includes a first strainer 36, a first solenoid valve 38, a second solenoid valve 40, a pressure regulating valve 42, a vacuum breaker 44, a check valve 46, and a sterilized water generator. A section 48 and a second strainer 50 are provided. The first strainer 36 is connected to an external water supply pipe (not shown), and the tap water flow path branches into two downstream of the first strainer 36. Note that the vacuum breaker 44 may not be provided.

One flow path 51 on the downstream side of the first strainer 36 is configured to directly supply tap water to the nozzle portion 32 via the first solenoid valve 38 . By opening the first solenoid valve 38, tap water is supplied to the nozzle section 32. The first electromagnetic valve 38 and the nozzle section 32 provided in one of the channels 51 spray tap water onto the washing area floor 12 to form residual water on the washing area floor 12 .

The other flow path 52 on the downstream side of the first strainer 36 includes, in order from the upstream side, a second solenoid valve 40, a pressure regulating valve 42, a vacuum breaker 44, a check valve 46, a sterilized water generator 48, and a second strainer. 50 is connected to supply sterilized water to the nozzle section 32. Note that the vacuum breaker 44 may not be provided.

The first solenoid valve 38 and the second solenoid valve 40 are configured to open the above-described flow paths 51 and 52 for tap water and to close the flow paths 51 and 52 for tap water, respectively. .

The pressure regulating valve 42 is designed to control the pressure of the supplied tap water. Thereby, the flow rate of tap water supplied to the sterilized water generating section 48, which will be described in detail later, can be adjusted to a desired value. By adjusting the flow rate of tap water supplied to the sterilized water generating section 48, the flow rate of the sterilized water supplied to the nozzle section 32 is adjusted. Note that, instead of or in addition to the pressure regulating valve 42, the second electromagnetic valve 40 may be used to adjust the flow rate of tap water.

The sterilized water generating section 48 is an electrolytic chamber (electrolytic cell) having an anode and a cathode. The sterilized water generation unit 48 generates sterilized water containing hypochlorous acid by applying a voltage between an anode and a cathode and electrolyzing tap water flowing between these electrodes. It has become. Since tap water contains chloride ions, hypochlorous acid is produced by electrolyzing the chloride ions. Here, the nozzle section 32 corresponds to a "sterilizing water spouting section."

The first electromagnetic valve 38, the second electromagnetic valve 40, the pressure regulating valve 42, and the sterilized water generating section 48 are controlled by the control device 30 as appropriate. Thereby, the sprinkling of tap water from the nozzle part 32 and the sprinkling of sterilizing water from the nozzle part 32 can be controlled independently from each other.

Specifically, the first solenoid valve 38 and the second solenoid valve 40 open and close the tap water channels 51 and 52 based on signals from the control device 30. Thereby, the flow rate of tap water supplied to the downstream side is controlled. Furthermore, the sterilizing water generation unit 48 switches the electrolysis chamber ON/OFF based on a signal from the control device 30 . In this way, the control device 30 controls the concentration of various constituent components in the sterilized water, the instantaneous flow rate (flow rate per unit time) of tap water and sterilized water, and the total amount of sterilized water that is spouted. can be controlled.

The above-mentioned sterilized water is functional water that has the function of reducing bacteria, mold, and yeast, and is, for example, water containing hypochlorous acid. Since tap water contains chloride ions, hypochlorous acid is produced by electrolyzing the chloride ions. As a result, the electrolyzed water changes into a liquid containing hypochlorous acid (HOCl). This hypochlorous acid is vaporized and becomes sterilized water gas (Cl ₂ O). This dichlorine monoxide is the active ingredient of sterilizing water gas.

The sterilized water may be metal ion water (for example, water containing metal ions such as silver ions, copper ions, or zinc ions) or water containing ozone. For example, when tap water is electrolyzed, acid (H ⁺ ) is consumed at the cathode, and the pH increases near the cathode. That is, alkaline water is generated near the cathode. On the other hand, alkali (OH ^- ) is consumed at the anode, and the pH decreases near the anode. That is, acidic water is generated near the anode. By changing the flow rate in the sterilized water generating section 48, the concentration of the components contained in the sterilized water can be controlled. In this case, metal ions such as silver, copper or zinc ions, or ozone (O ₃ ) are the vaporized active ingredients.

Although the above-mentioned sterilized water generation unit 48 generates sterilized water by electrolysis, the invention is not limited to this, and for example, sterilized water can be generated by dissolving a sterilizing agent in tap water. You may also do so.

In the present embodiment, "effective" in the active ingredient of vaporized sterilizing water refers to, for example, a sterilization rate of bacteria, mold, and yeast adhering to an object of 10% or more. To be more specific, the vaporized sterilizing water reduces the amount of bacteria, mold, and yeast attached to the object by 90%. The vaporized sterilizing water is defined as being effective if the following results occur:

In this embodiment, the nozzle section 32 is rotatably driven by an electric motor 53, although details will be described later. The electric motor 53 includes, for example, a stepping motor. The electric motor 53 is controlled by the control device 30. Thereby, the rotation angle and rotation speed of the nozzle portion 32 are changed by controlling the electric motor 53 based on a signal from the control device 30 (see FIGS. 13 and 14). Furthermore, an operation panel 28 equipped with a switch for starting sterilization work is connected to the control device 30, allowing bathroom users to perform appropriate operations other than sterilization work. ing.

As shown in FIGS. 5 and 6, the nozzle part 32 includes a first water passage part (retained water passage part) 54, a second water passage part (sterilized water passage part) 56, and a retained water passage part 54. It has a nozzle opening 58 for retained water formed in the section 54 and a nozzle opening 60 for sterilized water formed in the sterilized water passage section 56.

The tap water that has passed through the first electromagnetic valve 38 is supplied into the first flow path section 54 and is spouted from the first nozzle opening 58. The sterilized water generated by the sterilized water generation section 48 is supplied into the second water storage section 56 and is spouted from the second nozzle opening 60.

As shown in FIGS. 7 and 8, tap water is spouted from the retained water nozzle opening 58 so that it spreads in the vertical direction V against the surface of the washing area floor 12 to form a vertical plate shape. The sterilizing water is also spouted (sprayed) from the nozzle opening 60 so that it spreads in the vertical direction V to form a vertical plate shape on the surface of the washing area floor 12. Furthermore, the nozzle part 32 is rotated around its axis by the electric motor 53, and the nozzle part 32 swings along the washing area floor 12 as shown by the arrow S1, so that the tap water and sterilized water are spread horizontally. Water can be spouted over a wide range (25 degrees to 335 degrees, etc.) (see Figures 13 and 14).

Next, the bathroom drying device 26 provided on the ceiling 24 of the bathroom 1 will be described with reference to FIGS. 9 and 10. FIG. 9 is a cross-sectional view showing the bathroom drying device 26 in the “ventilation damper open state (ventilation state)”, and FIG. 10 is a cross-sectional view showing the bathroom drying device 26 in the “ventilation damper closed state (circulation state)”. be. In this circulating state, heating before bathing, heating during bathing, and "discharge of sterilizing water" are performed by the bathroom system 20 according to this embodiment. Note that the arrows in the figure indicate the flow of air.

As shown in FIG. 9, the bathroom drying device 26 includes a housing 70, and a lower portion of the housing 70 communicates with the interior of the bathroom 1 through an opening 72. A fan 74 is provided inside the housing 70 and rotated by an electric motor (not shown), and the rotation of the fan 74 sucks air in the bathroom 1 . Further, an exhaust damper 76 and a heater 78 are provided downstream of the fan 74 within the housing 70 . Furthermore, an exhaust port 79 is provided downstream of the exhaust damper 76.

As shown in FIG. 9, when the bathroom 1 is ventilated by the bathroom drying device 26, the exhaust damper 76 is opened, and the air inside the bathroom 1 sucked by the fan 74 is discharged to the outside from the exhaust port 79. It has become so.

Next, as shown in FIG. 10, when heating the inside of the bathroom 1 before and during bathing, the exhaust damper 76 is operated to close, and the air inside the bathroom 1 sucked by the fan 74 is transferred to the heater 78. The heated air is returned to the bathroom 1 through the opening 72 and the louver 80. In this way, the air in the bathroom 1 is circulated between the bathroom drying device 26 and the air in the bathroom 1 is maintained at a desired temperature (for example, 20° C.).

Further, a louver 80 is attached to the opening 72 on the downstream side of the heater 78, and the louver 80 includes a plurality of blades 80a. These plurality of blades 80a are interlocked by an electric motor 80b via a link mechanism, and the user operates the operation panel 28 to tilt the plurality of blades 80a at a predetermined angle to send air into the bathroom 1. The direction can be adjusted. Furthermore, when drying and heating the inside of the bathroom 1, the plurality of blades 80a swing as shown by arrow S2.

When the bathroom system 20 according to this embodiment performs "discharge of sterilized water," as shown in FIG. The heated air returns to the bathroom 1 through the opening 72, and the air in the bathroom 1 is circulated between the bathroom dryer 26 and the bathroom dryer 26.

At this time, the plurality of blades 80a of the louver 80 may be fixed at a predetermined angle to perform the circulation operation (see FIGS. 15 and 16), or the circulation operation may be performed by a swinging movement shown by arrow S2. (See Figure 17).
When this "sterilizing water spouting" is performed, the bathroom 1 is not ventilated, so the air in the bathroom 1 is confined within the bathroom 1. Since the inside of the bathroom 1 is a closed space, the effective components of the sterilizing water that is sprayed into the bathroom 1 and vaporized can be distributed throughout the bathroom without being discharged outside the bathroom.

Here, one period (cycle) of the swing motion of the plurality of blades 80a of the louver 80 of the bathroom drying device 26 is preferably in the range of 10 seconds to 60 seconds. One period (one cycle) is the time required for the blade to make one round trip.

Furthermore, as described above, since the nozzle section 32 that spews sterilized water is provided below the counter 16, it is It acts as a windbreak. Therefore, the sterilized water immediately after being discharged from the nozzle section 32 is prevented from directly hitting the air discharged from the bathroom drying device 26.

Next, with reference to FIGS. 11 and 12, "pre-washing" and "sterilizing water spouting" executed by the bathroom system 20 according to this embodiment will be explained. FIG. 11 is a time chart showing the operation of the bathroom system according to the embodiment of the present invention, and FIG. 12 is a flow chart showing the operation of the bathroom system according to the embodiment of the present invention.

First, as shown in FIG. 11, the bathroom drying device 26 ventilates the air in the bathroom 1 for a "predetermined time" of 12 minutes from the start of operation (see FIG. 9). This ventilation operation is preferably performed for a period of 1 minute to 60 minutes, including 12 minutes. In this ventilation state, the water discharging device 22 sprays water onto the washing area floor 12 of the bathroom 1 to perform "pre-washing".
Note that the sterilizing water is not spouted during the 12 minutes during which these ventilation operations and pre-washing are performed.

Next, after 12 minutes have elapsed from the start, the bathroom dryer 26 closes the exhaust damper 76 to stop ventilation (see FIG. 10), and the bathroom dryer 26 closes the exhaust damper 76 and stops ventilation for 34 minutes. 78 is turned on to warm the air in the bathroom 1 and circulate the warmed air within the bathroom 1.
After 12 minutes have elapsed since the start, the water spouting device 22 stops spouting water for 4 minutes and stands by. Thereafter, the water discharging device 22 intermittently performs "discharge of sterilizing water" for 30 minutes, and then ends "discharging of sterilizing water." This "period from the start of discharging sterilized water while circulating air until the end of dispensing sterilized water" is defined as the sterilized water dispensing process. Here, the intermittent operation in intermittent water spouting (a state in which sterilized water is turned off) is not limited to the state in which sterilized water is completely stopped (the state in which sterilized water is not being spouted), and the sterilized water This includes cases where a small amount of water is spewed out. Specifically, this includes those that discharge sterilized water at a rate of 50 ml/min or less, or those that discharge sterilized water at a flow rate of 20% or less compared to when the sterilized water is turned on. . Details of the intermittent sterilizing water spouting performed during this sterilizing water spouting period will be described later.

Here, as is clear from FIG. 11, the time for circulating air with the heater ON is 34 minutes, and the time for intermittently spouting sterilizing water (sterilizing water spouting step) is approximately 30 minutes. Both time periods overlap by 30 minutes, and the circulation operation and the sterilizing water spouting are controlled to be executed simultaneously during this overlapping time period.

When the water discharging device 22 is performing "sterilizing water discharging," the bathroom drying device 26 closes the exhaust damper 76 to stop ventilation, and warms the air in the bathroom 1 with the heater 78, as described above. Since the air is circulated, the discharged sterilizing water evaporates and evaporates due to the circulating air. Circulation of warm air is effective in vaporizing the sterilizing water, but the sterilizing water can also be vaporized by simply blowing air with the heater 78 turned off.

The bathroom drying device 26 closes the exhaust damper 76 and stops ventilation for a "predetermined time" of 26 minutes after the above-mentioned heater ON circulation and sterilizing water spouting are completed. While keeping the inside of the bathroom 1 as a closed space, the heater 78 is turned off to circulate the air in the bathroom 1. This 26-minute period from the end of spouting of sterilizing water with air being circulated until the end of air circulation is defined as the non-spraying process of sterilizing water. This heater OFF circulation operation is preferably executed in the range of 0 minutes to 29 minutes, including 26 minutes. The control unit 30 controls the bathroom drying device 26 and the water spouting device 22 so that the time for the sterilizing water spouting step is longer than the time for the sterilizing water non-spraying step. Thereby, the active ingredients remaining in the bathroom 1 after spraying of the sterilizing water can be firmly distributed in the bathroom, and the active ingredients of the sterilizing water can be spread throughout the bathroom 1.
Further, the control unit 30 controls the water discharging device so that the length of time between the spouting intervals of the sterilizing water intermittently spouted in the sterilizing water spouting process is shorter than the time in the sterilizing water non-spraying process. 22. By doing this, it is possible to secure enough time for the sterilizing water to finally be distributed in the bathroom 1 without taking too much time between spouting of the sterilizing water, which is performed multiple times intermittently. This allows the sterilizing water to act more firmly in the bathroom 1.

After this 26-minute heater OFF circulation operation (sterilized water non-discharge process) is completed, the bathtub dryer 26 opens the exhaust damper 76 to ventilate the air in the bathroom 1 for 24 hours (Fig. 9 ), then end ventilation.
In this embodiment, it is important that this ventilation operation is performed 26 minutes (0 to 29 minutes) after the heater ON circulation and sterilizing water spouting are completed. Therefore, the heater OFF circulation operation may not be performed.

Next, a control flow executed by the bathroom system according to this embodiment will be described with reference to FIG. 12. The basic operation of the control flow shown in FIG. 12 and the explanation using FIG. 11 described above is the same. Note that in FIG. 12, "S" indicates each step.

As shown in FIG. 12, in S1, a switch provided on the operation panel 26 for starting the operation of the bathroom system is turned on. Proceeding to S2, ventilation operation by the bathroom drying device 26 is started, and at the same time, a "prewash" operation by the water spouting device 22 is also started. Details of this "prewash" operation will be described later.
Next, the process advances to S3, and it is determined whether 12 minutes have elapsed. The operation of S2 is continued until 12 minutes have elapsed.

This "pre-washing" operation by the water spouting device 22 allows the necessary amount of residual water to be formed on the washing area floor 12, and the active ingredients of the vaporized sterilizing water are dissolved in this residual water, resulting in further sterilization. effect can be obtained.

If it is determined in S3 that 12 minutes have elapsed, the process proceeds to S4, where the ventilation operation by the drying device 26 is stopped (the exhaust damper is closed), and the "prewash" operation by the water discharging device 22 is also stopped.

Next, the process proceeds to S5, and it is determined whether or not the water discharging device 22 has stopped the "prewash" operation and waited for 4 minutes. Until the 4-minute wait, the process proceeds to S6, where it is determined whether the temperature in the bathroom is 20°C or higher. If it is not 20°C or higher, the process proceeds to S7, where the heater 78 of the drying device 26 is turned on, and the temperature inside the bathroom is Performs circulation operation that warms and circulates the air. The operation in S7 is executed immediately after the exhaust gas of the drying device is stopped in S4 if the temperature in the bathroom is not 20° C. or higher. Furthermore, if it is determined in S6 that the bathroom temperature is 20° C. or higher, the process proceeds to S8, and the drying device performs a circulation operation in which air is circulated with the exhaust damper closed.

If it is determined in S5 that the water spouting device 22 has waited for 4 minutes, the process advances to S9 and the water spouting device 22 starts "discharging sterilizing water." Details of this "sterilizing water spouting" will be described later.

Next, the process advances to S10, and the water spouting device 22 determines whether 30 minutes have passed since "sterilizing water spouting" was started. Until 30 minutes have elapsed, the process proceeds to S11, where it is determined whether the temperature in the bathroom is 20°C or higher, and if it is not 20°C or higher, the process proceeds to S12, where the drying device 26 keeps the exhaust damper 76 closed. , the heater 78 is turned on to perform a circulation operation that warms and circulates the air in the bathroom. The operation in S12 is executed immediately after the water spouting device 22 spouts sterilizing water in S9 if the temperature in the bathroom is not 20° C. or higher. Furthermore, if it is determined in S11 that the bathroom temperature is 20° C. or higher, the process proceeds to S13, where the drying device 26 performs a circulation operation to circulate air with the exhaust damper 76 closed.

In this way, the circulating air warmed by the drying device 26 acts on the sterilizing water spouted from the water spouting device 22, causing the sterilizing water to vaporize, and the vaporized sterilizing water to be sterilized. The active ingredients of the water are dissolved in the residual water remaining on the washing area floor 12, thereby improving the sterilization effect. Note that when the temperature in the bathroom is 20° C. or higher, the sterilizing water can be easily vaporized even if the heater 78 is turned off.

If it is determined in S10 that 30 minutes have elapsed since the water spouting device 22 started spouting sterilizing water, the process proceeds to S14, where the heater 78 of the drying device 26 is turned off and the exhaust damper 76 is closed. Perform circulation operation. At this time, the "discharge of sterilizing water" by the water discharging device 22 is stopped.

Next, the process advances to S15, and it is determined whether 26 minutes have elapsed since the heater 78 of the drying device 26 was turned off in S14. If 26 minutes have elapsed, the process advances to S16 and the circulation operation with the exhaust damper 76 of the drying device 26 closed is stopped. Next, the process proceeds to S17, and in the drying device 26, ventilation operation is continued for 24 hours with the exhaust damper 76 open. Thereby, the bathroom sterilization operation by the bathroom system according to the present embodiment is completed.

Next, the "prewash" operation performed by the water discharging device 22 will be described with reference to FIG. 13. FIG. 13 is a configuration diagram and a table illustrating the "prewash operation" performed by the bathroom system according to the embodiment of the present invention.

As shown in FIG. 13, tap water is spouted (sprinkled) from the retained water nozzle opening 58 of the nozzle portion 32 of the water spouting device 22 toward the washing area floor 12 of the bathroom 1. At this time, since the nozzle part 32 can rotate (swing motion), it sequentially executes operation 1 → operation 2 → operation 3 → operation 4 → operation 5 → operation 6 → operation 7 → operation 8 → operation 9. do. At this time, in operations 6 and 9, tap water is not spouted (water spouting OFF). Moreover, the range of tap water discharged is from 25 degrees to 335 degrees. Furthermore, when discharging tap water, the angular velocity at which the nozzle part 32 rotates is slow in the central area (operations 3, 4, 5) of the washing area floor 12, and in the both side areas (operations 1, 2, 7, 8). The tap water is sprayed as quickly as possible, and as much tap water as possible is sprinkled onto the central area of the washing area floor 12. Further, operations 1 to 9 are performed for about 4 minutes, and the water spouting operation of the water spouting device 22 is performed over three rounds, so tap water is spouted for a total of about 12 minutes.

Here, the washing area floor 12 of the bathroom 1 has a drainage slope (for example, 0.1 degrees to 11 degrees) that slopes downward toward the drain port 14 to such an extent that a predetermined amount of stagnant tap water remains. Thereby, the amount of tap water that remains on the washing area floor 12 can be set to a desired amount in which the active ingredients of the vaporized sterilizing water are dissolved.

Next, the "sterilizing water spouting" operation performed by the water spouting device 22 will be described with reference to FIGS. 11 and 14. FIG. 14 is a configuration diagram and a table explaining the "sterilizing water discharging operation" performed by the bathroom system according to the embodiment of the present invention.

As shown in FIG. 14, sterilized water is spouted from the sterilized water nozzle opening 60 of the nozzle portion 32 of the water spouting device 22 toward the washing area floor 12 of the bathroom 1. At this time, since the nozzle part 32 can rotate (swing motion), it sequentially executes operation 1 → operation 2 → operation 3 → operation 4 → operation 5 → operation 6 → operation 7. These operations 1 to 7 constitute one cycle (period). Further, the spraying range of sterilizing water is in the range of 25 degrees to 335 degrees. In addition, the angular velocity at which the nozzle part 32 rotates is slow in the central area (action 2, movement 5) of the washing area floor 12, and fast in both side areas (action 1, movement 3, movement 4, movement 6). As much sterilizing water as possible is spouted into the central area of the area 12. Furthermore, in operation 7, the discharge of sterilizing water is turned off. As a result, the sterilizing water is spouted from the nozzle part 32 of the water spouting device 22 for 30 seconds (=0.5 minutes) in operations 1 to 6, and then in operation 7, the nozzle part 32 is It stops for 45 seconds (=0.75 minutes) and is in a standby state without spouting sterilizing water (water spouting OFF). This operation is repeated 24 times. In other words, the nozzle section 32 operates for 24 cycles (periods).

Next, FIGS. 15 and 16 show the flow of sterilized water sprayed from the sterilized water nozzle opening 60 and the air discharged into the bathroom 1 from the bathroom dryer 26 when the ventilation damper is closed (circulation state). Explain the relationship between FIG. 15 is a front perspective view showing how the sterilizing water is discharged during the circulation operation performed by the bathroom system according to the embodiment of the present invention, and FIG. It is a perspective view seen from the side showing the state of sterilization water discharging during operation.

First, as shown in FIGS. 15 and 16, the sterilizing water is sprayed from the sterilizing water nozzle opening 60 onto the surface of the washing area floor 12 in the vertical direction to form a vertical plate shape. Furthermore, the sterilizing water nozzle opening 60 is making a rocking motion along the surface of the bathroom washing area floor 12, as shown by arrow S1. At this time, the angle of the blade 80a of the louver 80 of the bathroom drying device 26 is such that the air flow F1 discharged from the bathroom drying device 26 into the bathroom 1 is near the center position ( It is set at an angle such that when it moves to a position near the 180 degree position in FIG. 14, it hits the side of the sterilizing water sprayed in the form of a vertical plate.

In this state, when the sterilizing water sprayed in the vertical plate shape moves near the center position (near the 180 degree position in Figure 14), the air flow F1 directly hits the side of the vertical plate-shaped sterilizing water. The sterilizing water is effectively diffused into the bathroom 1. Furthermore, the air discharged from the bathroom drying device 26 collides with the washing area floor 12 and bounces off, and the flow F2 of this bounced air hits the sterilizing water that is sprayed in the form of a vertical plate. In this way, a state in which the air flow F1 directly hits the side surface of the vertical plate-shaped sterilizing water and a state in which the rebounded air flow F2 indirectly hits the sterilizing water sprayed in the vertical plate shape are repeated. It has become.

Furthermore, in this state, the nozzle part 32 of the water discharging device 22 is provided at a position below the top plate 16a of the counter 16 and retracted from the tip of the top plate 16a (see FIG. 4). The air flow F1 discharged from the bathroom drying device 26 is prevented from directly hitting the sterilizing water immediately after being sprayed from the sterilizing water nozzle opening 60 of the nozzle portion 32. In this way, the top plate 16a of the counter 16 functions as a "windbreak".

Next, with reference to FIG. 17, a case will be described in which the blade 80a of the louver 80 of the bathroom drying device 26 performs the swinging motion shown by the arrow S2 in FIG. 10. FIG. 17 is a front perspective view showing how the bathroom system according to the embodiment of the present invention spouts sterilizing water during a circulating operation in which the louver swings.

As shown in FIG. 17, the plurality of blades 80a of the louver 80 of the bathroom drying device 26 performs a rocking motion as indicated by the arrow S2, so the air F1 discharged into the bathroom 1 from the hot air heater 26 also swings. . Thereby, the air F1 hits the side surface of the vertical plate-shaped sterilizing water sprayed from the sterilizing water nozzle opening 60, and the position at which the air F1 hits the side surface of the sterilizing water changes in the vertical direction.

At this time, as described above, since the vertical plate-shaped sterilizing water sprayed from the sterilizing water nozzle opening 60 is making the oscillating motion as indicated by the arrow S1, the air flow F1 is caused by the vertical plate-shaped sterilizing water. The state in which the air directly hits the side surface of the bathroom 1 and the state in which the rebounded air flow F2 indirectly hits the sterilizing water sprayed in the form of a vertical plate are repeated. The air F1 also oscillates, and the position where it hits the side surface of the sterilizing water changes.

Further, one cycle of the oscillating motion of the sterilizing water indicated by the arrow S1 and one cycle of the oscillating motion of the blade 80a of the louver 80 indicated by the arrow S2 are set to have different values. On the condition that the values of the two periods are different, one period of the oscillating movement of the sterilizing water is preferably in the range of 10 seconds to 400 seconds, and one period of the oscillating movement of the louver 80 is in the range of 10 seconds to 60 seconds. A range of seconds is preferred. In this case, one period of the oscillating motion of the sterilizing water may be shorter than one period of the oscillating motion of the louver 80.

Next, referring again to FIG. 11, the amount of air discharged from the bathroom drying device 26 into the bathroom 1 will be described. First, in the bathroom system 20 according to the present embodiment, the bathroom drying device 26 performs "heater ON circulation" while discharging sterilizing water (30 minutes of intermittent sterilizing water discharging) and even after discharging sterilizing water. 34 minutes" and "heater OFF circulation 26 minutes" to circulate air in the bathroom.

Furthermore, in the present embodiment, the air circulation volume during the "heater ON circulation for 34 minutes" executed by the bathroom drying device 26 when the water discharging device executes "intermittent sterilizing water discharging for 30 minutes" is determined by the first circulation. Assuming that the air volume is Q1, and the second circulating air volume is Q2 when the bathroom drying device 26 "circulates the heater OFF for 26 minutes" after discharging sterilizing water is finished, then "first circulating air volume Q1>second circulating air volume Q2". The bathroom drying device 26 is controlled so that the following relationship is established.

At this time, the circulating air volume during the "sterilizing water OFF time" (corresponding to 45 seconds of standby) when "30 minutes of intermittent sterilizing water spouting" by the water spouting device is executed is defined as the third circulating air volume Q3.
In this case, the bathroom drying device 26 is controlled so that the relationship between these three circulating air volumes is "first circulating air volume Q1≧third circulating air volume Q3>second circulating air volume Q2".

Here, on the condition that the first circulating air volume Q1, the second circulating air volume Q2, and the third circulating air volume Q3 satisfy the relationship of the above-mentioned formula, the first circulating air volume Q1 is 50 m ³ /h to 250 m ³ /h. The second circulating air volume Q2 is preferably in the range of 1 m ³ /h to 99 m ³ /h, and the third circulating air volume Q3 is preferably in the range of 2 m ³ /h to 250 m ³ /h.

Next, with reference to FIG. 11, the operation of circulating air in the bathroom by the bathroom system 20 according to this embodiment will be described. After the bathroom drying device 26 performs ventilation operation for 12 minutes, the bathroom drying device 26 circulates air for 34 minutes (heater ON circulation for 34 minutes), and the water spouting device 22 spouts sterilizing water (intermittent). 30 minutes of sterilizing water spout). Of this 30 minutes of intermittent sterilizing water spouting, the time during which sterilizing water is being spouted is 12 minutes (=30 seconds of water spouting x 24 cycles). Therefore, if the time period during which sterilizing water is spouted while air circulation is performed is defined as the first predetermined time period, the first predetermined time period is 12 minutes. Here, the first predetermined time is preferably in the range of 6 minutes to 60 minutes, including 12 minutes.

Furthermore, in the bathroom system 20 according to this embodiment, air is circulated without discharging sterilized water. This time consists of 26 minutes of heater OFF circulation, 30 minutes of intermittent sterilization water spouting after 4 minutes of standby, and 18 minutes (= 45 seconds of waiting time) during which sterilization water is not spouted for 24 cycles. x 24 cycles = 1080 seconds). In this embodiment, during the "second predetermined time" which is 44 minutes, which is 18 minutes added to the 26 minutes, after the sterilizing water is first spouted, the air is discharged without spouting the sterilizing water. I try to circulate it. This second predetermined time is preferably in the range of 30 minutes to 54 minutes, including 44 minutes.

In the bathroom system 20 according to this embodiment, the bathroom drying device 26 and the water discharging device 22 are controlled so that the second predetermined time described above is longer than the first predetermined time.

As a modified example, sterilized water may not be spouted intermittently but sterilized water may be spouted continuously.In this case, the second predetermined period of time, ie, the "heater OFF circulation" period, may be changed to the air circulation period. It is necessary to set the time during which sterilizing water is spouted while performing the sterilization process to be longer than the first predetermined time.

FIG. 18 shows the spatial concentration of sterilized water in the bathroom over time at the time when the sterilized water is turned on and when the sterilized water is turned off when the sterilized water is continuously spouted by the bathroom system according to the present embodiment. It is a line diagram showing a change.
As shown in Figure 18, when sterilizing water is continuously spouted (sprayed), by making the sterilizing water OFF time longer than the sterilizing water ON time, the sterilizing water is Since sterilized water remains in the bathroom even during the water OFF time, the active ingredients remaining in the bathroom can be distributed throughout the bathroom.

Furthermore, as shown in FIG. 11, in the bathroom system 20 according to the present embodiment, after 30 minutes of intermittent sterilizing water spouting, "24-hour ventilation" is performed by the bathroom drying device 26. Here, this ventilation operation is preferably performed for a period of 1 hour to 24 hours, including 24 hours.

Next, the basic operation of the bathroom system according to this embodiment will be explained with reference mainly to FIGS. 11 and 12.
First, after use, all parts of the bathroom 1 are wet due to high humidity. Furthermore, dirt (keratin) remains on the surface of the washing area floor 12. Therefore, first, a ventilation operation is performed. Ventilation can reduce the humidity in the bathroom. Next, after a certain amount of ventilation, for example 12 minutes, the ventilation is stopped.

Next, while performing a ventilation operation, water is spouted by the water spouting device 22 to pre-wash the washing area floor for, for example, 12 minutes, and dirt (keratin) on the floor is washed away into the drain port 14.
Next, hot air circulation (heater ON circulation) is performed by the bathroom drying device 26 for 34 minutes, for example, to raise the temperature in the bathroom and create an environment in which the sterilized water is easily vaporized.

While hot air is being circulated, the water spouting device 22 intermittently (intermittently) spouts (sprays) sterilized water. Since the temperature in the bathroom increases, the sterilizing water is easily vaporized, and furthermore, by circulating hot air, the effective components of the vaporized sterilizing water can be spread to every corner of the bathroom 1. Furthermore, the active ingredients of the sterilizing water dissolve into the remaining water in the bathroom, exerting a sterilizing effect.

Next, the hot air circulation and sterilizing water spouting operations are stopped. Thereafter, the bathroom drying device 26 performs heater OFF circulation for 26 minutes, for example. At this time, heater ON circulation may be executed instead of heater OFF circulation. Furthermore, a ventilation operation may be performed during heater ON circulation.

Finally, the bathroom drying device 26 performs ventilation for 24 hours, for example, to dry the entire bathroom, and the sterilization work is completed.

Next, the effects of the bathroom system according to this embodiment will be explained.
First, in the bathroom system 20 according to the present embodiment, when the control device 30 receives a control command from the user, the bathroom drying device 26 performs the ventilation operation for a predetermined period of time, and then the bathroom drying device 26 Since the water spouting device 22 and the bathroom drying device 26 are controlled so that the circulating operation and water spouting device 22 executes the sterilizing water spraying operation and vaporizing the sterilized water, first, the water spouting device 22 and the bathroom drying device 26 are controlled so that the sterilizing water is easily vaporized. The humid air inside the bathroom 1 is exhausted to the outside, and then the sprayed (mist-like) sterilizing water is circulated inside the bathroom 1, so the active ingredients of the vaporized sterilizing water are poured into the bathroom 1. It can be distributed throughout the bathroom 1 to efficiently sterilize the inside of the bathroom 1.

Next, the control device 30 controls the water spouting device 22 and the bathroom drying device 26 so that at least a portion of the time periods in which the circulation operation of the bathroom drying device 26 and the sterilizing water spraying operation of the water spouting device 22 overlap overlap. Therefore, the circulation operation and the sterilizing water spraying operation can be performed at the same time, thereby actively vaporizing the sterilizing water and efficiently discharging the active ingredients of the vaporized sterilizing water into the bathroom 1 in a short time. It can be distributed within 1.

Next, the humidity in the bathroom 1 increases due to the sterilizing water sprayed into the bathroom 1, but if the ventilation operation is ended while the humidity remains elevated, mold and the like will grow in the bathroom 1, which is not desirable. Therefore, in the bathroom system 20 according to the present embodiment, the control device 30 causes the bathroom drying device 26 to restart the ventilation operation after the circulation operation of the bathroom drying device 26 and the sterilizing water spraying operation of the sterilizing water device are completed. Since the water discharging device 22 and the bathroom drying device 26 are controlled so as to execute the process, it is possible to prevent the growth of mold and the like in the bathroom 1.

Next, if the ventilation operation is performed immediately after the sterilizing water spraying operation of the water discharging device 22 ends, the effective components of the sterilizing water that have been distributed will also be immediately discharged to the outside of the bathroom 1, which is not preferable. Therefore, in the bathroom system 20 according to the present embodiment, the control device 30 controls the bathroom drying device 26 to restart ventilation after a predetermined period of time after the circulation operation of the bathroom drying device 26 and the sterilizing water spraying operation of the water discharging device 22 are completed. Since the water discharging device 22 and the bathroom drying device 26 are controlled to perform the operations, the effective components of the sterilizing water are not wasted.

Next, the control device 30 controls the water spouting device 22 and the bathroom drying device 26 so that the water spouting device 22 does not perform the sterilizing water spraying operation during the first ventilation operation performed by the bathroom drying device 26. It is possible to prevent wasteful use of bacterial water.

Next, in the bathroom system 20 according to the present embodiment, the water spouting device 22 spews water onto the washing area floor of the bathroom, and the control device 30 controls the water spouting device to spray water onto the bathroom washing area floor, and the control device 30 controls the water spouting device to spray water onto the washing area floor of the bathroom. Since the bathroom drying device 26 and the water spouting device 22 are controlled so as to spray water onto the washing area floor 12 of the bathroom, water is sprinkled onto the washing area floor 12 using the time during ventilation operation to remove sebum dirt, hair, etc. , to prepare for the subsequent sterilizing water spraying. Furthermore, since water is sprinkled during the ventilation operation, not only can the overall work time required for sterilizing the bathroom 1 be shortened, but also an increase in humidity due to water sprinkling can be suppressed.

Secondly, in the bathroom system 20 according to the present embodiment, the sterilized water is spread from the nozzle part 32 of the water discharging device 22 in the vertical direction to the surface of the washing area floor 12 of the bathroom 1 so as to form a vertical plate shape. Furthermore, the control device 30 controls the bathroom drying device 26 so that the air discharged into the bathroom 1 by the bathroom drying device 26 hits the side of the sterilizing water sprayed in a vertical plate shape. The sprayed sterilizing water can be efficiently diffused into the bathroom 1 by using the air discharged into the bathroom 1 by the drying device 26. Thereby, according to the present embodiment, the effective components of the sterilizing water can be vaporized and distributed throughout the bathroom 1 more efficiently.

Next, in the bathroom system 20 according to the present embodiment, a vertical plate-shaped sterilized water is sprayed from the nozzle part 32 of the water discharging device 22 so as to move along the surface of the washing area floor 12 of the bathroom 1, and the control device 30 shows a state in which the air discharged from the bathroom drying device 26 into the bathroom 1 hits the side surface of the sterilizing water sprayed in a vertical plate shape, and a state in which the air discharged into the bathroom 1 from the bathroom drying device 26 hits the washing area floor 12. The bathroom drying device 26 is controlled so that the air discharged from the bathroom drying device 26 into the bathroom 1 is vertically The sterilizing water directly hits the sides of the plate-shaped spray, and the sterilizing water is strongly dispersed, and the air that bounces off the wash area floor 12 indirectly hits the sides of the plate-shaped sterilizer. , the released sterilizing water can be diffused to the upper part of the bathroom 1. As a result, according to this embodiment, the effective components of the sterilizing water can be more efficiently vaporized and distributed throughout the bathroom.

In the bathroom system 20 according to the present embodiment, the control device 30 controls the bathroom drying device 26 so that the bathroom drying device 26 continues the circulation operation even after the nozzle section 32 of the water discharging device 22 finishes the sterilizing water spraying operation. Since the control is performed, the active ingredients of the sterilizing water can be firmly diffused in the bathroom 1 even after the sterilizing water is sprayed.

Since the sterilizing water immediately after being spouted from the sterilizing water spouting section spreads over a wide area, it is preferable to prevent the air discharged from the bathroom drying device 26 into the bathroom 1 from directly hitting the sterilizing water. For this reason, in this embodiment, a counter (windproof part) is provided to prevent the sterilized water immediately after being discharged from the nozzle portion 32 of the water discharging device 22 from directly hitting the air discharged from the bathroom drying device 26 into the bathroom 1. ) 16 is provided, so that after the sterilized water has spread thoroughly, the air discharged into the bathroom 1 from the bathroom drying device 26 can be directly applied to the sterilized water.

Thirdly, in the bathroom system 20 according to the present embodiment, the control device 30 controls the air discharged into the bathroom 1 by the bathroom drying device 26 to contact the side surface of the sterilized water sprayed and the side surface of the sterilized water of the air. Since the bathroom drying device 26 is controlled so that the position where it hits changes in the vertical direction, the air discharged from the bathroom drying device 26 into the bathroom 1 is used to efficiently spray the sprayed sterilized water into the bathroom 1. can be diffused within. As a result, according to this embodiment, the active ingredients of the sterilizing water can be more efficiently vaporized and distributed throughout the bathroom.

In the bathroom system 20 according to the present embodiment, the sterilized water is sprayed from the nozzle part 32 of the water discharging device 22 so as to move along the surface of the washing area floor 12 of the bathroom 1, so that it is sprayed from the bathroom drying device 26 into the bathroom 1. By using the discharged air, the sprayed sterilized water can be more efficiently diffused into the bathroom 1. As a result, according to this embodiment, the effective components of the sterilizing water can be vaporized and distributed throughout the bathroom more efficiently.

In the bathroom system according to the present embodiment, the control device 30 operates to change the time of one cycle of the swinging operation of the louver 80 of the bathroom drying device 26 and the spray direction of the sterilizing water nozzle opening 60 of the nozzle section 32. Since the bathroom drying device 26 and the water discharging device 22 are controlled so that the time of one cycle of Disinfectant water can be diffused. As a result, according to this embodiment, the active ingredients of the sterilizing water can be vaporized and distributed throughout the bathroom more efficiently.

In the bathroom system 20 according to the present embodiment, the control device 30 controls the bathroom drying device 26 so that the bathroom drying device 26 continues the circulation operation even after the nozzle section 32 of the water discharging device 22 finishes the sterilizing water spraying operation. Because of this control, even after spraying the sterilizing water, the active ingredients of the sterilizing water can be thoroughly diffused into the bathroom.

Since the sterilizing water immediately after being spouted from the sterilizing water spouting section spreads over a wide area, it is preferable to prevent the air discharged from the circulation device into the bathroom from directly hitting the sterilizing water. Therefore, in the bathroom system 20 according to the present embodiment, the sterilized water immediately after being discharged from the nozzle section 32 of the water discharging device 22 is prevented from directly hitting the air discharged from the bathroom drying device 26 into the bathroom 1. Since the counter (windproof part) 16 is provided, the air discharged into the bathroom 1 from the bathroom drying device 26 can be directly applied to the sterilized water after the sterilized water has spread thoroughly.

Fourthly, in the bathroom system 20 according to the present embodiment, the control device 30 controls the bathroom drying device 22 while discharging sterilizing water from the nozzle portion 32 of the water discharging device 22 and even after discharging the sterilizing water. controls the nozzle section 32 of the water spouting device 22 and the bathroom drying device 26 to perform a circulation operation that circulates the air in the bathroom 1, and further controls the air flow by the bathroom drying device 26 while spouting sterilized water. Since the bathroom drying device 26 is controlled so that the first circulating air volume is larger than the second circulating air volume after discharging the sterilizing water, a large amount of the sterilizing water is present in the bathroom 1. During this time, the circulating air volume is increased, which makes it possible to vaporize the highly concentrated active ingredients of the sterilizing water. On the other hand, there is a problem that the sterilized water leaks outside even during the circulation operation, but in this embodiment, after the sterilized water has been spouted, the circulation air volume is reduced, so that the sterilized water leaks out to the outside of the bathroom 1. It is also possible to reduce the amount of the active ingredients in the water, and the effective ingredients in the vaporized sterilizing water can be deposited all over the bathroom 1 by utilizing the time after the sterilizing water is spouted.

If sterilizing water is continued to be sprayed, the sterilizing water density (definition: ``sterilizing water concentration'' or ``amount of sterilizing water that can be dissolved in the air'') near the sterilizing water spray area becomes saturated. As a result, the vaporization efficiency of the sterilizing water decreases. In order to solve this problem, in this embodiment, sterilized water is spouted intermittently, that is, a sterilized water OFF time (time when sterilized water is not sprayed) is provided periodically, and this sterilized water OFF time is By replacing the saturated or nearly saturated air in the vicinity of the sterilizing water spray area, it is possible to suppress a decrease in the vaporization efficiency of the sterilizing water. As a result, according to this embodiment, the sterilizing water can be spread throughout the bathroom without spraying an unnecessarily large amount of sterilizing water. In addition, by discharging sterilized water intermittently, compared to continuous spraying of sterilized water, sterilized water can be saved, and the electrodes in the device that generates sterilized water can wear out. This also makes it possible to suppress energy consumption and power consumption.

In the bathroom system 20 according to the present embodiment, the control device 30 controls the third circulation air volume by the bathroom drying device 28 to be adjusted to the second circulation during the sterilization water OFF time of the intermittent spouting of sterilization water from the nozzle part 32 of the water spouting device 22. Since the bathroom drying device 26 is controlled to be larger than the air volume, the saturated or nearly saturated air near the sterilizing water spray area can be easily replaced even in a short period of time, and the evaporation efficiency of the sterilizing water can be improved even more effectively. can be suppressed from decreasing.

In the bathroom system 20 according to the present embodiment, the control device 30 circulates the air in the bathroom 1 after the nozzle part 32 of the water spouting device 22 spews sterilized water, and then performs ventilation in the bathroom 1. Since the bathroom drying device 26 is controlled so as to perform the following, it is possible to prevent an increase in humidity due to the sterilizing water remaining in the bathroom 1 and to suppress mold stains.

Fifth, in the bathroom system 20 according to the present embodiment, the control device 30 controls the nozzles of the bathroom drying device 26 and the water spouting device 22 to spout sterilized water while circulating air during the first predetermined time period. 32, and for a second predetermined period of time, the nozzles of the bathroom drying device 26 and the water spouting device 22 are configured to circulate air without spouting sterilized water after first spouting sterilized water. 32, the active ingredients remaining in the bathroom 1 after spraying sterilizing water can be distributed throughout the bathroom 1, and even a small amount of sterilizing water can be used efficiently without unnecessary spraying of sterilizing water. The active ingredients of the sterilizing water can be spread throughout the bathroom.

In the bathroom system 20 according to the present embodiment, the control device 30 determines that the second predetermined time (time during which air is circulated without discharging sterilized water after discharging sterilized water for the first time) is the first predetermined time (time during which air is circulated without discharging sterilized water). Since the nozzle section 32 of the bathroom drying device 26 and water spouting device 22 is controlled so that the time for discharging sterilized water while circulating the sterilized water is longer than the time for discharging sterilized water, As a result, the active ingredients can be applied to the entire bathroom over time without spraying an unnecessary large amount of sterilized water, and the active ingredients can be applied to every corner of the bathroom. This can prevent bacteria and mold stains.

In the bathroom system 20 according to the present embodiment, the control device 30 executes air circulation in the bathroom 1 after discharging sterilized water from the nozzle part 32 of the water discharging device 22, and then performs ventilation in the bathroom 1. Since the bathroom drying device 26 is controlled so as to perform the following, it is possible to prevent an increase in humidity due to the sterilizing water remaining in the bathroom 1 and to suppress mold stains.
