Description

[Technical Field]

[0001] The present invention relates to a bathroom sterilization system capable of sterilizing a bathroom using sterilizing water such as ozone water, and a sterilizing water spraying device used to configure this system. [Background technology]

[0002] Specific examples of bathroom sterilization systems include those described in Patent Documents 1 to 3. The bathroom sterilization systems described in these documents have a sterilizing water sprayer installed on the ceiling or other part of the bathroom, and ozone water as sterilizing water can be sprayed into the bathroom from the nozzle of this sterilizing water sprayer. Spraying ozone water into the bathroom provides the sterilizing effect of the ozone water, which is preferable for keeping the bathroom hygienic.

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

[0004] That is, the nozzle of the disinfectant water sprayer is configured to spray disinfectant water at a substantially uniform amount to each part of the bathroom. However, the degree of dirt in the bathroom is not uniform throughout, and generally, the washing area is often dirtier than the area where the bathtub is installed. For this reason, in the above-mentioned conventional technology, when disinfectant water is sprayed into the bathroom, a sufficient disinfecting effect is obtained in the area where the bathtub is installed, but a sufficient disinfecting effect is not obtained in the washing area. It is desirable to be able to appropriately resolve this issue. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2024-2058 [Patent Document 2] Japanese Patent Publication No. 2024-2325 [Patent Document 3] Japanese Patent Application Laid-Open No. 2024-2326 [Patent Document 4] Patent No. 6827169 [Patent Document 5] Patent No. 5104100 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention was conceived under the circumstances described above, and its objective is to provide a bathroom sterilization system that can eliminate the risk of insufficient sterilization of the washing area and effectively sterilize almost the entire bathroom, as well as a sterilizing water sprayer for use in the system. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides the following technical solutions.

[0008] A bathroom sterilization system provided by a first aspect of the present invention comprises a bathroom in which a bathtub installation area and a washing area are adjacent to each other, and a disinfecting water spraying device capable of spraying disinfecting water into the bathroom using a nozzle located at or above the bathroom, wherein the nozzle has an internally hollow nozzle main body with a cylindrical peripheral wall, and a plurality of nozzle holes provided in the peripheral wall so that disinfecting water supplied into the nozzle main body can be sprayed radially outward from the peripheral wall, and the nozzle is located above the bathtub installation area or at an upper position closer to the bathtub installation area than the center of the washing area, and the plurality of nozzle holes include a plurality of first nozzle holes provided at intervals in the circumferential direction around the entire peripheral area of ​​the peripheral wall so that the disinfecting water can be sprayed radially in all four directions of the peripheral wall. and a plurality of second nozzle holes that are located above or below the plurality of first nozzle holes and are provided in a limited area of ​​the peripheral wall that is biased toward the washing area so that the disinfecting water can be sprayed in a concentrated manner toward the washing area.

[0009] This configuration provides the following effects. That is, because disinfecting water is sprayed radially from the nozzle's multiple first nozzle holes in all directions around the peripheral wall of the nozzle, the disinfecting water can be applied to a wide area of ​​the bathroom, such as the area where the bathtub is installed, the washing area, and their side walls. On the other hand, the disinfecting water sprayed from the multiple second nozzle holes can be sprayed intensively onto the washing area. Therefore, even if the washing area is dirtier than the bathtub area, it is possible to eliminate the problem of insufficient or slightly insufficient disinfection of the washing area, effectively disinfect each part of a wide area (almost the entire area) of the bathroom, and keep the bathroom hygienic.

[0010] In the present invention, preferably, each of the first nozzle holes opens obliquely downward from the nozzle body, and each of the second nozzle holes is located above each of the first nozzle holes and opens horizontally or in a direction closer to horizontal than each of the first nozzle holes.

[0011] With this configuration, disinfecting water is sprayed obliquely downward from each first nozzle hole. In contrast, disinfecting water is sprayed horizontally or approximately horizontally from each second nozzle hole located above each first nozzle hole. Therefore, it is possible to prevent the disinfecting water sprayed from each first nozzle hole and the disinfecting water sprayed from each second nozzle hole from interfering with each other. If the disinfecting water sprayed from each first and second nozzle hole interferes with each other, it may be difficult to properly spray disinfecting water to the desired disinfecting water spray target area. However, with the above configuration, it is possible to appropriately eliminate such a risk.

[0012] In the present invention, preferably, the peripheral wall portion of the nozzle is formed with an inclined cylindrical wall portion whose outer diameter decreases toward the bottom, and a non-inclined cylindrical wall portion located above this inclined cylindrical wall portion, and each of the first nozzle holes is provided in the inclined cylindrical wall portion, while each of the second nozzle holes is provided in the non-inclined cylindrical wall portion.

[0013] This configuration provides the following effects. That is, when the depth direction (drilling direction) of each first nozzle hole is aligned with a direction perpendicular to the outer surface of the inclined cylindrical wall portion, each first nozzle hole opens facing obliquely downward. Furthermore, when the depth direction (drilling direction) of each second nozzle hole is aligned with a direction perpendicular to the outer surface of the non-inclined cylindrical wall portion, each second nozzle hole opens horizontally. Therefore, when manufacturing a nozzle, the process of providing each first nozzle hole that opens facing obliquely downward and the process of providing each second nozzle hole that is located above each first nozzle hole and opens horizontally can be simplified and streamlined.

[0014] In the present invention, the first and second nozzle holes are preferably nozzle holes that spray sterilizing water in the form of threads.

[0015] With this configuration, compared to spraying disinfecting water as a mist, it is possible to more effectively deliver disinfecting water to the desired disinfecting water spray target area, thereby enhancing the disinfecting effect. Furthermore, when disinfecting water is sprayed as a mist, a phenomenon in which gas containing disinfecting components is liberated or volatilized from the disinfecting water before the disinfecting water reaches the bathroom wall surface or the like (e.g., a phenomenon in which ozone gas is liberated from ozone water used as disinfecting water) is likely to occur. In contrast, with the above configuration, it is possible to suppress such a phenomenon and further enhance the disinfecting effect.

[0016] In the present invention, preferably, the device further comprises a bathroom drying device that is installed above or on the top of the bathroom and is capable of blowing air into the bathroom from a louver for blowing air, and a housing that houses the blower, and the disinfectant water sprayer is assembled to the bathroom drying device, and the nozzle and the louver are both provided on the underside of the housing, and the louver is positioned on the side of the nozzle opposite to the side on which each of the second nozzle holes in the peripheral wall is provided.

[0017] With this configuration, the disinfecting water sprayer is assembled to the bathroom drying device, and the two devices can be integrated to suitably achieve a compact overall size and reduced manufacturing costs. Also, the disinfecting water sprayed from each second nozzle hole of the nozzle does not proceed toward the louver, so the louver does not get wet with the disinfecting water.

[0018] In the present invention, preferably, the disinfecting water ejected from each of the first nozzle holes travels at a position lower than the louvers and does not fall on the louvers.

[0019] This configuration prevents the louvers from getting wet even with the disinfecting water sprayed from each of the first nozzle holes of the nozzle, thereby keeping the louvers dry and preventing mold and mildew, and also preventing the disinfecting water from dripping below the louvers.

[0020] A disinfectant water spraying device provided by a second aspect of the present invention is installed and used above or above a bathroom in which a bathtub installation area and a washing area are adjacent to each other, and is equipped with a nozzle for spraying disinfectant water into the bathroom from above or above, the nozzle having an internally hollow nozzle main body with a cylindrical peripheral wall, and a plurality of nozzle holes provided in the peripheral wall so that disinfectant water supplied into the nozzle main body can be sprayed radially outward from the peripheral wall, and is a disinfectant water spraying device characterized in that the plurality of nozzle holes include a plurality of first nozzle holes provided at intervals in the circumferential direction around the entire peripheral area of ​​the peripheral wall so that the disinfectant water can be sprayed radially in all four directions of the peripheral wall, and a plurality of second nozzle holes located above or below the plurality of first nozzle holes and provided in a limited circumferential area of ​​the peripheral wall.

[0021] A disinfecting water spraying device configured in this manner is useful for constructing a bathroom disinfection system provided by the first aspect of the present invention, and can achieve the effects already described for the bathroom disinfection system.

[0022] 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 2] 2 is a schematic cross-sectional view of a main part of a bathroom drying device equipped with a disinfecting water spraying device that constitutes the bathroom disinfection system shown in FIG. 1.

[Figure 4] (a) is a cross-sectional view of the nozzle of the disinfecting water spraying device shown in Figure 2, (b) is a bottom view of arrow IVb in (a), and (c) is a cross-sectional view of IVc-IVc in (a). DETAILED DESCRIPTION OF THE INVENTION

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the drawings.

[0025] The bathroom sterilization system SY shown in Figures 1 and 2 includes a bathroom drying device A incorporating a sterilizing water sprayer B. The bathroom drying device A is configured by combining a main body A0 installed on the ceiling 10 of the bathroom 1 (corresponding to the upper or upper part of the bathroom 1) with a separate remote control 2. In this embodiment, the sterilized water is ozone water. As the non-sterilized water, tap water, for example, is used. Bathroom 1 is a room in which the area where bathtub 11 is installed (bathtub installation area 1b) and the washing area 1a are adjacent to each other, and is surrounded by a plurality of side walls 12 (including doors not shown).

[0026] 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.

[0027] Main body A0 of bathroom drying device A includes blower fan 60 (also called a circulation fan), heat exchanger 31 for heating air, ventilation fan 32 for bathroom 1, control unit 5, and housings 34, 34a that house these components. The blower fan 60 draws air from the bathroom 1 through an air intake port 62 provided on the underside of the housing 34, and can blow the air into the bathroom 1 through a blower louver 61 provided at the air outlet. The louver 61 is movable and can swing around a support shaft 61a by the driving force of a motor (not shown).

[0028] Heat exchanger 31 heats the air drawn into blower fan 60 through air intake port 62, and heated hot water can be supplied to heat exchanger 31 from water heater 8 as a medium for this heating. When blower fan 60 is driven and heated hot water is supplied from water heater 8 to heat exchanger 31, hot air is blown from louver 61 into bathroom 1, allowing bathroom 1 to dry. When the supply of heated hot water to heat exchanger 31 is stopped, unheated air (unheated air) can be blown from louver 61 into bathroom 1. Ventilation fan 32 can draw air from bathroom 1 into housing 34 through air inlet 62 and exhaust it to the outside through exhaust outlet 37.

[0029] The disinfecting water spraying device B is an apparatus capable of performing a disinfecting water spraying step of spraying ozone water as disinfecting water into the bathroom 1. However, it is also capable of performing a non-disinfecting water spraying step of spraying tap water as non-disinfecting water into the bathroom 1 instead of disinfecting water. This disinfecting water spraying device 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 9 provided in the water sealing section 7A, and a spray nozzle 4 located at the end of the water supply piping section 7. The 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.

[0030] The ozone water generator 9 is a type that generates ozone water by, for example, electrolyzing water. When the on-off valve Va is opened and the ozone water generator 9 is turned on, the ozone water generated in the ozone water generator 9 is sprayed from the nozzle 4 into the bathroom 1 (a sterilized water spraying process is executed). On the other hand, when the ozone water generator 9 is turned off, tap water is sprayed from the nozzle 4 toward the bathroom 1 (a non-sterilized water spraying process is executed).

[0031] The water sealing section 7A of the water supply piping section 7 is a section where water is stored when the on-off valve Va is closed and water supply to the water supply piping section 7 is stopped, and has a falling section 70 whose height decreases toward the downstream side, and a rising section 72 connected to the downstream side via a connecting section 71 and whose height increases toward the downstream side. Since the ozone water generating device 9 is provided in the water sealing section 7A, even when water supply to the water supply piping section 7 is stopped, the inside of the ozone water generating device 9 (hydroelectric The chamber for water flow in which the electrodes for gas decomposition are provided can be filled with water. If the water is discharged from the chamber and the chamber becomes dry, the amount of precipitates from the ozonated water or tap water increases, which may cause clogging or a decrease in the conductivity of the electrodes. However, according to this embodiment, such problems can be suppressed.

[0032] 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 4.

[0033] As clearly shown in FIGS. 3 and 4, the nozzle 4 has a nozzle body 40, an upper cover 49, and a plurality of first and second nozzle holes 41a, 41b. Nozzle body 40 has a hollow interior, such as a cup shape, with a cylindrical peripheral wall 43 and a bottom wall 44 that closes the lower portion. Top cover 49 is connected to nozzle body 40 via fasteners 80, such as bolts, so as to close the top surface of nozzle body 40. Water supply piping 7 penetrates top cover 49, allowing ozone water or tap water to be supplied into nozzle body 40. Nozzle 4 is supported by an appropriate bracket 38, and nozzle body 40 is configured so that all or part of it protrudes below panel 35 on the underside of housing 34 of bathroom drying device A.

[0034] A portion of the peripheral wall 43 of the nozzle main body 40 near its lower end is an inclined cylindrical wall 43a whose outer and inner diameters decrease toward the bottom. The region of the peripheral wall 43 adjacent to and above the inclined cylindrical wall 43a is a non-inclined cylindrical wall 43b that is cylindrical (cylindrical) and not inclined in the vertical height direction.

[0035] The first and second nozzle holes 41a, 41b are holes for spraying ozone water or tap water. These first and second nozzle holes 41a, 41b are each formed as a circular hole with an opening diameter of, for example, about 0.7 mm, so that the ozone water or tap water can be sprayed in a thread-like form rather than as a mist.

[0036] The plurality of first nozzle holes 41a are arranged at an appropriate interval in the circumferential direction over the entire periphery of the inclined cylindrical wall portion 43a of the peripheral wall portion 43 so that ozone water or tap water can be sprayed radially in all directions of the peripheral wall portion 43. The depth direction (drilling direction) of the plurality of first nozzle holes 41a coincides with the thickness direction of the inclined cylindrical wall portion 43a, and the holes are open facing diagonally downward in the nozzle main body portion 40.

[0037] The second nozzle holes 41b are provided in the non-inclined cylindrical wall portion 43b so as to be positioned above the first nozzle holes 41a, and are spaced apart at appropriate intervals in the circumferential direction. However, the second nozzle holes 41b are not provided over the entire circumferential area of ​​the peripheral wall portion 43 (non-inclined cylindrical wall portion 43b), but are provided only in a region Sa that is approximately half of the non-inclined cylindrical wall portion 43b (see FIG. 4(c)). A region Sb on the opposite side of the peripheral wall portion 43 from the region Sa is a nozzle hole absent region Sb where the second nozzle holes 41b are not provided.

[0038] Here, the nozzle 4 is located above the bathtub installation area 1b (however, it can also be configured to be located above the bathtub installation area 1b rather than the center of the washing area 1a, for example, near the boundary between the bathtub installation area 1b and the washing area 1a). The area Sa where the plurality of second nozzle holes 41b are provided is used for supplying ozone water or tap water to the washing area 1a. The nozzle 4 has a peripheral wall 43 (non-inclined cylindrical wall 43b) biased toward the washing area 1a so that ozone water can be sprayed intensively onto the washing area 1a. The spraying of ozone water onto the washing area 1a does not only involve the ozone water directly falling onto the floor 13 of the washing area 1a, but also includes situations in which the ozone water hits the side wall 12 of the washing area 1a and flows onto the floor 13 of the washing area 1a. The first and second nozzle holes 41a, 41b may be arranged at the same or different pitches, and may have different opening diameters.

[0039] The air blowing louver 61 is provided on the underside of the housing 34, similar to the nozzle 4, but is located on the side of the nozzle 4 opposite the area Sa where the plurality of second nozzle holes 41b of the nozzle 4 are provided, i.e., on the side directly facing the nozzle hole absent area Sb. As a result, the ozone water ejected from the plurality of second nozzle holes 41b does not proceed toward the louver 61 and does not wet the louver 61. On the other hand, the ozone water is ejected obliquely downward from the plurality of first nozzle holes 41a. This ozone water advances below the louver 61 and does not get on the louver 61, regardless of the angle at which the louver 61 swings.

[0040] Preferably, the louver 61 is capable of continuously blowing air onto the nozzle 4 for a predetermined period of time or more. With this configuration, if water droplets adhere to the nozzle 4, the air blowing action can remove or reduce the water droplets, thereby preventing the water droplets from falling below the nozzle 4.

[0041] Control unit 5 is configured using a microcomputer and other devices, and performs operational control and data processing for each component of bathroom drying apparatus A. Control unit 5 is also capable of wireless data communication with remote control 2 via communication unit 50 (however, control unit 5 and remote control 2 can alternatively be configured to communicate via wired cable). 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 configured using an LCD or other device and capable of displaying various data, and speaker SP. Control unit 22 and control unit 5 cooperate to perform operational control, such as sterilization of bathroom 1 using sterilizing water sprayer B, and various data processing.

[0042] In this bathroom sterilization system SY, control units 22, 5 can be used to carry out a bathroom sterilization process that executes a sterilizing water spraying process in which ozone water is sprayed into bathroom 1, but prior to this, a non-sterilizing water spraying process is carried out in which tap water is sprayed into bathroom 1 as a pre-cleaning step. After the sterilizing water spraying process is completed, a non-sterilizing water spraying process is carried out as a sterilizing water rinsing process. After that, a bathroom ventilation process using ventilation fan 32 and a bathroom drying process in which warm air is blown into bathroom 1 are carried out in sequence.

[0043] Next, the operation of the bathroom sterilization system SY will be described.

[0044] First, when the disinfecting water spraying process is performed, disinfecting water is sprayed radially from the multiple first nozzle holes 41a of the nozzle 4 toward all four sides of the peripheral wall portion 43 of the nozzle 4. This allows the disinfecting water to act on a wide area, such as the bathtub installation area 1b of the bathroom 1, the washing area 1a, and the surrounding side wall 12. On the other hand, the disinfecting water sprayed from the multiple second nozzle holes 41b is sprayed intensively onto the washing area 1a. Therefore, even if the washing area 1a is more seriously soiled than the bathtub installation area 1b, a large amount of disinfecting water can be sprayed onto this washing area 1a, effectively disinfecting it.

[0045] In addition, ozone water is sprayed from the first and second nozzle holes 41a and 41b of the nozzle 4. When the plurality of second nozzle holes 41b are positioned vertically, ozone water is sprayed horizontally from the plurality of second nozzle holes 41b. In contrast, the plurality of first nozzle holes 41a are positioned lower than the plurality of second nozzle holes 41b and spray ozone water obliquely downward. Therefore, the ozone water sprayed from each of the first and second nozzle holes 41a, 41b is less likely to interfere with each other. If the ozone water sprayed from each of the first and second nozzle holes 41a, 41b interfere with each other, it may be difficult to properly spray the ozone water to the desired disinfecting water spray target area. However, according to this embodiment, such a risk can be appropriately eliminated.

[0046] Furthermore, the ozone water is sprayed in a thread-like form from the first and second nozzle holes 41a, 41b. Therefore, compared to spraying ozone water as a mist, the ozone water can be more effectively delivered to the desired disinfectant water spray target area. Furthermore, when ozone water is sprayed as a mist, ozone gas is likely to be liberated from the ozone water before it reaches various parts of the bathroom 1, such as the sidewall 12. This increases the ozone gas concentration in the bathroom 1, resulting in a strong ozone odor, which may be unpleasant for the user. In contrast, this embodiment appropriately eliminates such concerns, and the entire bathroom 1 can be properly disinfected and kept hygienic through a disinfection process using ozone water.

[0047] During the ozone water spraying process, for example, ventilation fan 32 and blower fan 60 are both driven to simultaneously ventilate and circulate air in bathroom 1. In this case, louver 61 swings about support shaft 61a and protrudes below panel 35, but the ozone water sprayed from first and second nozzle holes 41a, 41b does not splash onto louver 61. This makes it possible to appropriately avoid problems such as ozone water splashing onto louver 61 and then dripping below nozzle 4, causing the user to get wet.

[0048] Before and after the disinfecting water spraying process, a pre-cleaning process for the bathroom 1 and a non-sterilizing water spraying process as a disinfecting water rinsing process are performed. In this non-sterilizing water spraying process, tap water is sprayed into the bathroom 1 from the nozzle 4 instead of ozone water, but the manner in which this tap water is sprayed is the same as the manner in which ozone water is sprayed. That is, tap water is sprayed over a wide area of ​​the bathroom 1 from the multiple first nozzle holes 41a, and tap water is sprayed intensively into the washing area 1a from the multiple second nozzle holes 41b. Therefore, even if the washing area 1a is highly soiled, it is possible to effectively perform a pre-cleaning process using tap water and rinse off ozone water (sterilizing water rinsing). Of course, the tap water sprayed from the nozzle 4 does not splash on the louver 61.

[0049] In this embodiment, for example, after the non-sterilized water spraying step as the sterilized water rinsing step is completed, air can be continuously blown from louver 61 toward nozzle 4 for an appropriate period of time or more to remove or reduce water droplets adhering to the outer surface of nozzle 4. Therefore, water droplets falling below nozzle 4 can also be appropriately prevented.

[0050] Additionally, in this embodiment, the peripheral wall 43 of the nozzle 4 is formed with an inclined cylindrical wall portion 43a and a non-inclined cylindrical wall portion 43b located above it, and the first and second nozzle holes 41a, 41b are provided in these portions, respectively. This makes it easy to provide the first nozzle hole 41a as an opening facing diagonally downward and the second nozzle hole 41b as a horizontal opening located above the first nozzle hole 41a. This also helps reduce the manufacturing cost of the nozzle 4.

[0051] The present invention is not limited to the above-described embodiment. The specific configurations of the bathroom sterilization system and sterilizing water sprayer according to the present invention can be freely designed and modified within the intended scope of the present invention.

[0052] In the above-described embodiment, the first nozzle holes 41a open obliquely downward and the second nozzle holes 41b open horizontally, but the present invention is not limited to this. For example, both the first and second nozzle holes 41b may open obliquely downward or horizontally. Furthermore, while in the above-described embodiment, the second nozzle hole 41b is located above the first nozzle hole 41a, the present invention may be configured differently, with the second nozzle hole 41b located below the first nozzle hole 41a. If there is a risk that the disinfecting water (ozone water) sprayed from the first and second nozzle holes 41a, 41b may interfere with each other, a means for reducing this risk may be employed in which the first and second nozzle holes 41a, 41b are arranged to be offset from each other in the circumferential direction, so that the disinfecting water sprayed from the first and second nozzle holes 41a, 41b will be offset from each other in a plan view of the bathroom 1 and will not interfere with each other.

[0053] In the above-described embodiment, the first and second nozzle holes 41 a, 41 b are provided in one row each in the vertical height direction, but the present invention is not limited to this. Either or both of the first and second nozzle holes 41 a, 41 b may be provided in multiple rows in the vertical height direction (i.e., for example, a configuration may be adopted in which a plurality of first nozzle holes are provided in two upper and lower rows spaced apart in the circumferential direction, and above them a plurality of second nozzle holes are provided in two upper and lower rows spaced apart in the circumferential direction). In the present invention, it is also possible to configure the nozzle so that a nozzle hole other than the first and second nozzle holes (another nozzle hole that may also be called a third nozzle hole) is further provided in the nozzle, as long as the intended effect of the present invention is not impaired.

[0054] The disinfecting water may be sprayed from the first and second nozzle holes in the form of a mist rather than a thread. The specific opening diameter, opening shape, and number of the first and second nozzle holes can be freely changed. The disinfecting water may be sprayed continuously or intermittently at predetermined short intervals. The number of nozzles is not limited to one, but may be multiple.

[0055] The disinfectant water may be any liquid that exhibits disinfecting properties and is not limited to ozone water. For example, other types of disinfectant water, such as hypochlorous acid water, may also be used. Therefore, the disinfectant water generator is not limited to an ozone water generator. Furthermore, the specific method for generating disinfectant water and the concentration of specific components in the generated disinfectant water are not limited. The non-sterilized water is not limited to tap water, and water other than tap water, such as well water pumped up by a pump, can also be used.

[0056] In the above-described embodiment, the disinfecting 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.
