Description

[Technical Field]

[0001] The present invention relates to a bathroom sterilization system that can sterilize a bathroom using sterilizing water such as ozone water. [Background technology]

[0002] Specific examples of bathroom sterilization systems include those described in Patent Documents 1 and 2. The bathroom sterilization systems described in these documents are equipped with a sterilizing water / non-sterilizing water spraying device that can perform a sterilizing water spraying process in which ozone water, which is sterilizing water, is sprayed into the bathroom from a nozzle located at the top of the bathroom, and a non-sterilizing water spraying process in which ordinary water, such as tap water, which is non-sterilizing water, is sprayed. According to this configuration, after disinfecting the bathroom with ozone water, ordinary water (non-ozone water) can be sprayed into the bathroom to rinse away the ozone water. This prevents a large amount of ozone water and the ozone gas liberated from the ozone water from remaining in the bathroom for a long period of time. As a result, if there are components or parts in the bathroom that are not resistant to ozone water, these components or parts can be protected. Furthermore, if the ozone gas concentration in the bathroom is high, the strong odor characteristic of ozone can be unpleasant for the user and potentially harmful to the user's health. However, this configuration can mitigate such risks.

[0003] However, the above-mentioned prior art still has room for improvement, as will be described below.

[0004] For example, when a disinfectant water spraying process is being performed as part of a bathroom disinfection process, a user may operate a remote control to stop the bathroom disinfection process. In this case, in the prior art, control corresponding to the remote control operation is performed to stop the disinfectant water spraying process and the bathroom disinfection process. After the disinfection process is stopped, no special operational control is performed. However, if the disinfectant water spraying process is interrupted midway, the disinfectant water (ozone water) that had been sprayed up until that point remains in the bathroom. This can lead to deterioration of components and parts that are not resistant to ozone water, and the concentration of ozone gas in the bathroom can increase, causing the user to feel uncomfortable due to the ozone odor. Therefore, it is desirable to appropriately suppress such risks.

[0005] As disinfectant water, there are other types of disinfectant water besides ozone water, such as hypochlorous acid water, but when using such other types of disinfectant water, the same situation as described above can occur. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2020-48858 [Patent Document 2] Japanese Patent Application Publication No. 2019-166278 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention was conceived in light of the circumstances described above, and its objective is to provide a bathroom sterilization system that can prevent sterilized water and its free gases from remaining in the bathroom for a long period of time if the bathroom sterilization process is stopped midway, and can appropriately prevent or suppress discomfort to the user. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides the following technical solutions.

[0009] The bathroom sterilization system provided by the present invention comprises a sterilizing water / non-sterilizing water spraying device capable of performing a sterilizing water spraying process and a non-sterilizing water spraying process into a bathroom, a ventilation device capable of performing a bathroom ventilation process that exhausts the air in the bathroom to the outside, and an operating means that can be operated to start the sterilization treatment of the bathroom, wherein the bathroom sterilization treatment is a process that sequentially performs at least the sterilizing water spraying process, the non-sterilizing water spraying process as a sterilizing water rinsing process after the sterilizing water spraying process, and the subsequent bathroom ventilation process, and is characterized in that when the bathroom sterilization treatment is stopped during the sterilizing water spraying process, a specified maintenance operation is started, and this maintenance operation is configured to sequentially perform the sterilizing water rinsing process and the subsequent bathroom ventilation process.

[0010] This configuration provides the following effects. That is, when the bathroom sterilization process is stopped midway through the disinfectant water spraying process, a predetermined maintenance operation (a disinfectant water rinsing process and a subsequent bathroom ventilation process) is then performed. This prevents the disinfectant water already sprayed in the bathroom from remaining, and also actively expels liberated or volatilized gases from the disinfectant water outside the bathroom. This effectively eliminates problems such as excessive deterioration of bathroom components and parts that are not resistant to disinfectant water, and unpleasant odors caused by the increased concentration of liberated or volatilized gases from the disinfectant water in the bathroom.

[0011] In the present invention, it is preferable that even if the sterilization treatment of the bathroom is stopped within a predetermined period after the end of the sterilization water spraying process, the maintenance operation is started after the sterilization treatment is stopped.

[0012] This configuration provides the following effects. That is, even if the sterilization treatment of the bathroom is stopped after the sterilizing water spraying process is completed, the sterilizing water that has already been sprayed may remain in the bathroom, just as if the sterilizing water spraying process was stopped midway. Even in such a case, the maintenance operation is started after that, so that the sterilized water is discharged from the bathroom and the free gas or volatile gas from the sterilized water is discharged appropriately, and problems caused by the sterilized water and the gas can be appropriately resolved.

[0013] In the present invention, it is preferable that during the maintenance operation, an operation to turn off the maintenance operation by operating the operating means is invalid.

[0014] This configuration provides the following effects. In other words, if the maintenance operation is stopped midway, there is a risk that the sterilized water or free or volatile gases from the sterilized water will remain in the bathroom. In contrast, with the above configuration, the user cannot stop the maintenance operation midway by operating the operating means, so it is possible to appropriately eliminate the above-mentioned risk.

[0015] In the present invention, preferably, the apparatus further comprises a notification means for notifying, during the maintenance operation, the time required from the present time until the maintenance operation is completed.

[0016] This configuration is convenient because it allows the user to know when the maintenance operation will be completed.

[0017] In the present invention, it is preferable that the sterilization treatment of the bathroom is completed before the start of the sterilizing water spraying step. When the power supply is stopped, the maintenance operation is not performed.

[0018] This configuration provides the following effects. In other words, if the bathroom sterilization process is stopped before the sterilizing water spraying step starts, and maintenance operation is performed afterwards, unlike the above configuration, the maintenance operation would be wasted or nearly wasted.In contrast, the above configuration can eliminate such waste.

[0019] In the present invention, it is preferable that when a predetermined first abnormality occurs during the execution of the bathroom sterilization process, which requires the operation of the bathroom sterilization system to be stopped, the bathroom sterilization process is stopped at that point, and the maintenance operation is not performed thereafter.

[0020] With this configuration, when a specified first abnormality occurs, which is a serious abnormality that requires the operation of the bathroom sterilization system to be stopped, not only is the bathroom sterilization process stopped, but subsequent maintenance operations are also not performed, thereby appropriately avoiding, for example, the system being operated in a dangerous state.

[0021] In the present invention, it is preferable that a bathroom drying process for drying the bathroom can also be executed, and when a specified second abnormality that does not require the operation of the bathroom sterilization system to be stopped occurs between the start of the bathroom sterilization process and the start of the sterilizing water spraying process, the bathroom sterilization process is stopped at that point, and thereafter the sterilizing water spraying process is omitted, and the non-sterilizing water spraying process, the bathroom ventilation process, and the bathroom drying process are executed sequentially.

[0022] With this configuration, if a predetermined second abnormality occurs before the disinfecting water spraying process is initiated, which is a relatively minor abnormality that does not require the bathroom disinfection system to be shut down, the bathroom disinfection process is stopped at that point, thereby appropriately preventing the disinfecting water spraying process from being performed in an inappropriate manner. On the other hand, after the bathroom disinfection process is stopped, the non-disinfecting water spraying process, the bathroom ventilation process, and the bathroom drying process are performed sequentially, resulting in a bathroom cleaning process similar to the bathroom disinfection process, allowing the bathroom to be restored to a hygienic state that the user originally intended. Furthermore, the bathroom drying process is finally performed, preventing the bathroom from remaining wet with non-disinfecting water or the like, thereby preventing mold and mildew. This also prevents discomfort to the user.

[0023] Other features and advantages of the present invention will become more apparent from the following description of the preferred embodiments of the invention, which proceeds with reference to the accompanying drawings. [Brief explanation of the drawings]

[Figure 4] 3 is a flowchart showing an example of an operational processing procedure executed in the bathroom sterilization system shown in FIGS. 1 and 2. DETAILED DESCRIPTION OF THE INVENTION

[0025] Preferred embodiments of the present invention will now be described in detail with reference to the drawings.

[0026] The bathroom sterilization system SY shown in Figures 1 and 2 is equipped with a sterilized water / non-sterilized water spraying device 4. The bathroom drying device A is comprised of a main body A0 installed on the ceiling 10 of the bathroom 1 where the bathtub 11 is installed, and a separate remote control 2. In this embodiment, ozone water is used as the sterilized water, and tap water is used as the non-sterilized water, which will be described later. As will be described later, sterilized water / non-sterilized water sprayer 4 can selectively spray either ozone water or tap water from nozzle 43 into bathroom 1.

[0027] Bathroom drying apparatus A can receive hot water from water heater 8. Water heater 8 can supply hot water to bathtub 11 via piping 80, and also has the function of supplying general hot water to the kitchen and other areas. It also has bathroom remote control 81A and kitchen remote control 81B.

[0028] The main body A0 of the bathroom drying device A includes a blower 6 having a blower fan 60 (also called a circulation fan), a heat exchanger 31 for heating air, a ventilation fan 32 for the bathroom 1, a control unit 5, and housings 34, 34a that house these components.

[0029] By driving blower fan 60, blower device 6 can draw air from bathroom 1 through air inlet 62 provided on the underside of housing 34 and blow air into bathroom 1 via louver 61 provided at the air outlet. Louver 61 can rotate around support shaft 61a, and the angle of rotation (air blowing direction) can be freely changed using a motor (not shown) as a drive source.

[0030] Heat exchanger 31 heats the air drawn into blower fan 60 through air inlet 62, and heated hot water can be supplied to heat exchanger 31 from water heater 8 as the heating medium. When blower fan 60 is driven and heated hot water is supplied from water heater 8 to heat exchanger 31, the air drawn in through air inlet 62 is heated, and heated air (warm air) is blown into bathroom 1 through louver 61. When bathroom drying device A is in bathroom drying mode, the warm air blowing and bathroom ventilation by ventilation fan 32 are carried out in parallel, as described below. When the supply of heated hot water to heat exchanger 31 is stopped, unheated air (unheated air) can be blown into bathroom 1 through louver 61.

[0031] Ventilation fan 32 is an example of the "ventilation device" defined in this invention, and is a fan for exhausting air (including ozone gas, described below) from bathroom 1 to the outdoors. When ventilation fan 32 is operated, air from bathroom 1 is drawn into housing 34 through air inlet 62, enters the area where ventilation fan 32 is installed, and is exhausted to the outdoors through exhaust outlet 37. Preferably, the rotation speed of ventilation fan 32 is variable, so that the ventilation air volume in bathroom 1 can be increased or decreased.

[0032] As described above, disinfected water / non-sterilized water sprayer 4 is an apparatus that can selectively perform either a disinfected water spraying step in which ozone water as disinfected water is sprayed into bathroom 1, or a non-sterilized water spraying step in which tap water as non-sterilized water is sprayed into bathroom 1. This disinfected water / non-sterilized water sprayer 4 is equipped with a water supply piping section 7 that receives tap water from the outside, a water sealing section 7A provided in this water supply piping section 7, an ozone water generator 42 provided in the water sealing section 7A, and a spray nozzle 43 located at the end of the water supply piping section 7. In addition, water supply piping section 7 is further equipped with an on-off valve Va such as a solenoid valve, a flow rate sensor Sa, a temperature sensor Sb for detecting water temperature, a pressure reducing valve 79, and first and second atmosphere release valves V1 and V2.

[0033] The ozone water generator 42 is of a type that generates ozone water by, for example, electrolyzing water. When the on-off valve Va is opened and the ozone water generator 42 is turned on, the ozone water generated in the ozone water generator 42 is sprayed from the nozzle 43 toward the bathroom 1 (a disinfecting water spraying process is executed). In this disinfecting water spraying process, the disinfecting water (ozone The zonal water is sprayed onto, for example, almost the entire area of ​​each side wall surface 12 of the bathroom 1 except for the upper portions, the bathtub 11, and almost the entire floor surface 13 of the washing area 1a. On the other hand, when the ozone water generator 42 is turned off, tap water is sprayed from the nozzle 43 toward the bathroom 1 (the non-sterilized water spraying process is executed).

[0034] Nozzle 43 has a hollow nozzle body 43a into which ozone water or tap water flowing through water supply piping 7 flows, and multiple small-diameter nozzle holes 43b for spraying water are provided in the approximately cylindrical peripheral wall of nozzle body 43a. Nozzle 43 is supported by an appropriate bracket 38, and the entire nozzle body 43a or a region near the bottom thereof protrudes downward from panel 35 on the bottom side of bathroom drying device A. However, the specific configuration of nozzle 43 for sprinkling water is not limited to this.

[0035] The water sealing section 7A of the water supply piping 7 is a section where water is stored when the on-off valve Va is closed and water supply to the water supply piping 7 is stopped. It has a falling section 70 that decreases in height toward the downstream side, and a rising section 72 that is connected to the downstream side via a connecting section 71 and increases in height toward the downstream side. Because the ozone water generator 42 is provided in the water sealing section 7A, the inside of the ozone water generator 42 (the water flow chamber in which the electrodes for water electrolysis are provided) can be filled with water even when water supply to the water supply piping 7 is stopped. If the chamber is drained and becomes dry, the amount of precipitates from the ozone water or tap water increases, which can cause clogging or reduced electrode conductivity. However, this embodiment can prevent such problems.

[0036] The first and second atmosphere release valves V1 and V2 are both valves that are set to an open state when the on-off valve Va is in a closed state. The first atmosphere release valve V1 serves to prevent water from backflowing upstream from the water seal section 7A when negative pressure occurs upstream of the water supply piping section 7, and is positioned at a height of at least an appropriate dimension H above the highest water level of the water seal section 7A (the height of the piping section 74 connected to the water seal section 7A). The second atmosphere release valve V2 serves to drain water from the piping section 73 connected downstream of the water seal section 7A to the outside through the nozzle 43.

[0037] Control unit 5 is configured using a microcomputer and other devices, and performs operational control and data processing for each component of bathroom drying device A. Control unit 5 is also capable of wireless data communication with remote control 2 via communication unit 50. Remote control 2 is, for example, portable and includes a communication circuit (not shown) for wirelessly communicating with control unit 5 via communication unit 50, control unit 22, multiple operation switches 20 for issuing various operational commands, display unit 21, which is configured using an LCD display or the like and can display various data, and speaker SP. Multiple operation switches 20 are an example of the "operation means" defined in the present invention, and display unit 21 is an example of the "notification means" defined in the present invention. Control unit 5 and remote control 2 can also be configured to communicate via wired communication. Control unit 22 and control unit 5 cooperate with each other to control operations such as the sterilization process of bathroom 1 using sterilized water / non-sterilized water sprayer 4, and to process various data, the details of which will be described later.

[0038] Next, a specific example of the operational process executed in the bathroom sterilization system SY and its operation will be described.

[0039] In the bathroom sterilization system SY, it is possible to start the sterilization process of the bathroom 1 by performing a specific operation using the remote control 2. In this sterilization process of the bathroom 1, a predetermined number of steps S1 to S5 are grouped together and these steps are executed sequentially, as shown in Figure 3(a). Specifically, there are three steps: a non-sterilized water spraying step S1, a sterilized water spraying step S2, and a sterilized water rinsing step. The non-sterilized water spraying step S3, the bathroom ventilation step S4, and the bathroom drying step S5 are carried out in this order.

[0040] Here, the non-sterilized water spraying step S1 corresponds to a preliminary cleaning step in which tap water is sprayed onto the bathroom 1 to wash away dirt from various parts of the bathroom 1 prior to the sterilized water spraying step S2. This non-sterilized water spraying step S1 also serves to lower the room temperature of the bathroom 1 if the room temperature is high. If the room temperature of the bathroom 1 remains high and ozone water is sprayed as described below, there is a risk that the ozone gas concentration in the bathroom 1 will become excessively high. In contrast, the non-sterilized water spraying step serves to lower the room temperature of the bathroom 1 before the sterilized water spraying step is executed, thereby eliminating the risk of the ozone gas concentration becoming excessively high. If the room temperature of the bathroom 1 is high, such as immediately after a user has finished bathing, the non-sterilized water spraying step can be executed to sufficiently lower the room temperature of the bathroom 1. The non-sterilized water spraying step S1 ends, for example, when its execution time reaches a predetermined time. This also applies to the other steps S2 to S5, but other conditions can also be used as the end conditions (for example, when the amount of spraying reaches a predetermined amount, when the degree of dryness reaches a predetermined state, etc.).

[0041] The disinfecting water spraying step S2 is a step of spraying ozone water into the bathroom 1, and therefore disinfects the bathroom 1 using the ozone water. The non-sterilized water spraying step S3 corresponds to a sterilized water rinsing step in which the ozone water sprayed into the bathroom 1 is washed away with tap water and then discharged to the outside through a drain (not shown) of the bathroom 1. This step S3 prevents the sterilized water from remaining on various parts of the bathroom 1 for an unnecessarily long period of time. Bathroom ventilation step S4 is a step of ventilating bathroom 1 to reduce the ozone gas concentration in bathroom 1. If the ozone gas concentration in bathroom 1 is high, ozone gas may leak outside bathroom 1, causing discomfort to residents with its ozone odor or posing a risk to the health of anyone who unexpectedly enters bathroom 1. Bathroom ventilation step S4 can appropriately reduce such risks. Ventilation fan 32 is kept on continuously from the start to the end of the sterilization process of bathroom 1, but during bathroom ventilation step S4, the driving speed of ventilation fan 32 is set higher than before. Bathroom drying step S5 is a step in which warm air is blown into bathroom 1 to dry it, which is preferable for keeping bathroom 1 hygienic. During this step, ventilation fan 32 is driven at the same speed as when bathroom ventilation step S4 is performed. The sterilization process for bathroom 1 is completed when bathroom drying step S5 is completed.

[0042] On the other hand, in this bathroom sterilization system SY, if the sterilization process of the bathroom 1 is stopped midway, a "maintenance operation" is executed under predetermined conditions. 3(b), the maintenance operation is performed after the non-sterilized water spraying step S6, which is a sterilized water rinsing step, is followed by the bathroom ventilation step S7. The execution times of the non-sterilized water spraying step S6 and the bathroom ventilation step S7 are the same as, for example, the non-sterilized water spraying step S3 and the bathroom ventilation step S4 in the bathroom sterilization treatment, but can also be different times.

[0043] Next, with reference to FIG. 4, the operational control of the bathroom sterilization system SY will be described in more detail.

[0044] First, the sterilization process of the bathroom 1 is started (S10), and then the remote control 2 may be operated to stop the sterilization process of the bathroom 1 (S11: YES). In this case, if the operation is performed before the sterilizing water spraying step S2, the sterilization process of the bathroom 1 is stopped at that point, and the maintenance operation is not performed thereafter (S12: YES, S13). If the sterilization process of the bathroom 1 is stopped without the sterilizing water spraying step S2 being performed, the maintenance operation However, according to the above-described operation process, such a waste does not occur.

[0045] Unlike the above, if an operation to stop the sterilization treatment of bathroom 1 is performed during the sterilizing water spraying step S2, the sterilization treatment of bathroom 1 is stopped at that point, and maintenance operation is then started (S12: NO, S20: YES, S21, S22). Furthermore, the time required from the current time until the maintenance operation is completed is displayed on display unit 21 of remote control 2 (S23). Note that the display of the required time may be configured to start when the operation in step S25 described below is performed, instead of when the maintenance operation starts.

[0046] The specific details of the maintenance operation have been described above, and the ozone water sprayed into bathroom 1 during the period up until disinfecting water spraying process S2 is stopped is discharged outside bathroom 1 in non-disinfecting water spraying process S6, and ozone gas is discharged outside bathroom 1 in bathroom ventilation process S7. This prevents ozone water and ozone gas from remaining in bathroom 1 for a long period of time, preventing deterioration of components and parts that are less resistant to ozone water and properly eliminating problems such as users feeling uncomfortable due to the ozone odor.

[0047] While the maintenance operation is in progress, any operation of the remote control 2 to stop the maintenance operation is invalidated, and the maintenance operation continues until it is completed (S24: NO, S25: YES, S26, S24: YES). This operational control prevents the maintenance operation from being interrupted midway, preventing a large amount of ozone water or ozone gas from remaining in the bathroom 1. Preferably, when an invalid operation is attempted, an operation rejection sound is generated so that the user can detect it.

[0048] Furthermore, unlike the above, even if an operation to stop the sterilization process of bathroom 1 is performed during a predetermined period after the end of sterilizing water spraying process S2, the same operational control as described above when sterilizing water spraying process S2 is stopped midway is executed (S20: NO, S27: YES, S21-S26). If sterilizing water spraying process S2 ends and, for example, non-sterilizing water spraying process S3, which serves as a sterilizing water rinse-off process, is stopped midway, the sterilizing water may not be sufficiently rinsed away, and a large amount of ozone water may remain in bathroom 1. According to the above operational control, maintenance operation is started afterward, thereby appropriately eliminating the above-mentioned risk.

[0049] If the operation to stop the sterilization treatment of bathroom 1 is performed after the end of sterilizing water spraying step S2 but not during the specified period, the sterilization treatment of bathroom 1 is stopped at the time of the operation, and no maintenance operation is performed thereafter (S27: NO, S28). In such a case, there is no need for maintenance operation, and unnecessary maintenance operation is appropriately avoided.

[0050] In this bathroom sterilization system SY, even if the remote control 2 is not operated to stop the sterilization process of the bathroom 1, the sterilization process of the bathroom 1 is configured to be stopped when an abnormality occurs (S11: NO, S14: NO, S15 to S19). The specific contents are as follows.

[0051] That is, with regard to abnormalities in this bathroom sterilization system SY, predetermined first and second abnormalities are determined in advance, and the data is stored in a memory unit that the control units 22,5 have. Here, the first abnormality is a serious abnormality, such as a motor abnormality in the ventilation fan 32 or a water leak from the water supply piping section 7, which means that the sterilization process in the bathroom 1 should not be performed and the bathroom sterilization system SY should be turned off. The second abnormality is, for example, an abnormality in the flow rate detection value of the water supply pipe section 7 or an abnormality in the water temperature detection value, and is not as serious as the first abnormality, but is a malfunction that may occur during the sterilization process of the bathroom 1. This is an abnormality that is thought to mean that the disinfected water spraying step S2 should not be carried out. It is possible to determine that the first and second abnormalities have occurred when a predetermined abnormal phenomenon occurs a predetermined number of times. For example, even if the phenomenon that is the subject of determination as to whether the second abnormality has occurred occurs only once, it is possible to prevent the occurrence of the second abnormality from being determined if the number of occurrences does not reach a predetermined number. Of course, it is also possible to determine that the second abnormality has occurred when the phenomenon occurs only once.

[0052] If the first abnormality occurs during the sterilization process of bathroom 1, the sterilization process of bathroom 1 is immediately stopped and maintenance operation is not performed (S15: YES, S16). This prevents a serious accident from occurring in the bathroom sterilization system SY.

[0053] On the other hand, if the second abnormality described above occurs before disinfecting water spraying step S2 during the disinfection process of bathroom 1, the disinfection process is stopped, and the non-disinfecting water spraying step S3, bathroom ventilation step S4, and bathroom drying step S5 are sequentially executed with disinfecting water spraying step S2 omitted (S15: NO, S17: YES, S18, S19). This operational control prevents the execution of disinfecting water spraying step S2 when the second abnormality occurs, eliminating the possibility of an inappropriate disinfecting water spraying step S2 being executed, for example, by spraying too much or too little disinfecting water. Furthermore, the non-disinfecting water spraying step S3, bathroom ventilation step S4, and bathroom drying step S5 executed after the disinfection process of bathroom 1 is stopped perform a bathroom cleaning process similar to the disinfection process of bathroom 1, thereby restoring bathroom 1 to a hygienic state that the user originally intended. Finally, a bathroom drying step S5 is carried out to prevent the bathroom 1 from remaining wet with non-sterilized water, etc., and to effectively prevent mold, etc.

[0054] In contrast to the above, a second abnormality may occur during or after the disinfecting water spraying step S2. In this case, although not shown in Figure 4, the disinfecting process of bathroom 1 can be continued without being interrupted.

[0055] Preferably, when the first or second abnormality occurs, an error code indicating the content of the abnormality is displayed on the display unit 21. Furthermore, there are cases where a maintenance operation is performed in a state where some minor abnormality has occurred, even though a final determination that the first or second abnormality has occurred has not been reached. In such cases, for example, an error code indicating the content of the abnormality is displayed when the maintenance operation is completed.

[0056] The present invention is not limited to the above-described embodiment, and the specific configuration of each part of the bathroom sterilization system according to the present invention can be freely modified in various ways within the intended scope of the present invention.

[0057] In the above-described embodiment, when the disinfecting water spraying step is performed, a non-disinfecting water spraying step is performed prior to it, but the present invention is not limited to this, and the non-disinfecting water spraying step may be omitted, or a step other than the non-disinfecting water spraying step may be performed before the disinfecting water spraying step is performed. Also, in the above-described embodiment, the bathroom ventilation step and the bathroom drying step are performed as separate steps, but the bathroom ventilation step in the present invention can also be a step that serves as the bathroom drying step.

[0058] The disinfecting water is not limited to ozone water as long as it is a liquid that has a disinfecting effect. For example, other types of disinfecting water, such as hypochlorous acid water, can also be used. The non-sterilized water is not limited to tap water. For example, water other than tap water, such as well water pumped up by a pump, can also be used.

[0059] In the sterilized water / non-sterilized water spraying device 4 of the above embodiment, the ozone water generating device 42 is turned on. By switching it to off, it is possible to spray both sterilized water and non-sterilized water from one common nozzle 43, but the present invention is not limited to this. The sterilized water / non-sterilized water sprayer of the present invention may be configured, for example, as a combination of a sterilizing water sprayer capable of spraying sterilized water from a first nozzle and a non-sterilized water sprayer configured as a separate device from the sterilizing water sprayer and capable of spraying non-sterilized water from a second nozzle. The disinfectant water / non-sterilized water sprayer may be configured to spray disinfectant water and non-sterilized water into a bathroom, and the specific method for generating the disinfectant water and the concentration of specific components in the generated disinfectant water are not limited. The nozzle may be configured differently from the above-described embodiment, and multiple nozzles may be used instead of a single nozzle, and the specific number of nozzles is not important. Furthermore, disinfectant water and non-sterilized water may be sprayed intermittently, for example, at a predetermined short interval, instead of continuously.

[0060] In the above-described embodiment, the disinfected water / non-disinfected water spraying device is incorporated into the bathroom drying device, but the present invention is not limited to this, and it is also possible to configure it so that it is not incorporated into the bathroom drying device.
