Description

[Technical Field]

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

[0002] A specific example of a bathroom sterilization system is one that includes an ozone water spraying device that can spray ozone water, which is sterilizing water, into the bathroom, as described in Patent Document 1, for example. With this configuration, ozone water with a disinfecting effect is sprayed into the bathroom, thereby disinfecting various parts of the bathroom, such as the walls, and suppressing the growth of mold, bacteria, and other microorganisms.

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

[0004] In other words, when ozone water is sprayed into a bathroom, ozone gas is liberated from the ozone water. If the ozone gas concentration in the bathroom becomes high, the odor characteristic of ozone becomes strong, making the user feel uncomfortable and potentially harming the user's health. In response to this, after spraying ozone water into the bathroom to disinfect it, the bathroom is typically ventilated and dried using, for example, a ventilation fan or a bathroom dryer, to sufficiently reduce the ozone concentration. However, if the bathroom door louver is blocked during ventilation, or if dust clogs a portion of the exhaust fan's exhaust port, preventing the exhaust fan from performing at its full potential, the ozone gas concentration in the bathroom may not decrease sufficiently for a long period of time. If the user were to operate a specific switch under such circumstances and restart the disinfecting water spraying process, the ozone gas concentration in the bathroom would rise significantly (see the comparative example in Figure 5, described later), potentially posing a risk to the user's health. Therefore, it is desirable to appropriately prevent such situations.

[0005] In addition, disinfectant water other than ozone water includes, for example, 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 Application Publication No. 2024-2058 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention was conceived under the circumstances described above, and its objective is to provide a bathroom sterilization system that can appropriately prevent the concentration of gases, such as liberated gases from sterilizing water, from becoming excessively high when sterilizing a bathroom. [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 disinfecting water spraying device capable of executing a disinfecting water spraying process into the bathroom to disinfect the bathroom, and an operating means capable of operating the device to perform the disinfecting water spraying process, and a re-sterilization prohibition period in which the operation-on operation by the operating means is invalid for a predetermined period after the disinfecting water spraying process by the disinfecting water spraying device has ended, and the disinfecting water spraying process is prohibited from being performed again. The present invention is characterized in that it is configured to be between.

[0010] This configuration provides the following effects. That is, when a disinfecting water spraying process is executed to disinfect the bathroom, if not much time has passed since the disinfecting water spraying process was completed and the user attempts to re-execute the disinfecting water spraying process during the re-sterilization prohibition period, the operation is invalidated and the disinfecting water spraying process is not re-executed. Therefore, unlike the conventional technology, it is possible to prevent the concentration of the free gas or volatile gas from the disinfecting water from becoming excessively high, which would be caused by the disinfecting water spraying process being re-executed at a stage when not much time has passed since the disinfecting water spraying process was completed and the concentration of the free gas or volatile gas from the disinfecting water in the bathroom has not yet sufficiently decreased. As a result, it is possible to appropriately prevent or suppress the user from feeling uncomfortable or harming the user's body due to a high concentration of free gas or volatile gas from the disinfecting water.

[0011] In the present invention, preferably, the device further includes an alarm means capable of performing an alarm operation to inform the user that the operation is invalid when the user turns on the device during the re-sterilization prohibition period.

[0012] According to this configuration, when a user turns on the device to execute the disinfecting water spraying process during the re-sterilization prohibition period and the operation is invalidated, a predetermined notification operation is performed. Therefore, the user can accurately detect that the operation on the device has been invalidated based on the fact that the current time is the re-sterilization prohibition period, which is convenient.

[0013] In the present invention, preferably, the period from the start to the end of the disinfecting water spraying process is also included in the re-sterilization prohibition period, and even if the disinfecting water spraying process is stopped midway, the disinfecting water spraying process is prohibited from being executed again until the re-sterilization prohibition period ends.

[0014] This configuration provides the following effects. In other words, even if the disinfecting water spraying process is stopped midway and then immediately attempted to be restarted, the period falls within the re-sterilization prohibition period, making it possible to prevent the disinfecting water spraying process from being restarted. When the disinfecting water spraying process is stopped midway, disinfecting water was sprayed into the bathroom before the cancellation, so a certain amount of free gas or volatile gas from the disinfecting water is present in the bathroom. According to the above configuration, restarting the disinfecting water spraying process in such a situation is avoided, which is even more preferable in terms of preventing the concentration of the gas from becoming abnormally high.

[0015] In the present invention, the prohibition period for re-sterilization is preferably a period during which it is expected that the concentration of free gas or volatile gas from the sterilizing water in the bathroom will exceed a predetermined safety standard concentration if the sterilizing water spraying process is restarted after the sterilizing water spraying process has been completed or stopped midway.

[0016] This configuration can appropriately prevent the problem of the concentration of free gas or volatile gas exceeding a predetermined safety standard concentration due to an excessively short re-sterilization prohibition period, while also appropriately avoiding the problem of user inconvenience due to an excessively long re-sterilization prohibition period.

[0017] In the present invention, preferably, a re-sterilization prohibition period changing means is further provided, which is capable of changing at least one of the start, end, and length of the re-sterilization prohibition period.

[0018] With this configuration, the size of the bathroom, the capacity of the disinfectant water spraying device, the needs of the user, etc. This is convenient because it makes it possible to set an appropriate period for prohibiting re-sterilization, taking into consideration various conditions, such as the desire for re-sterilization.

[0019] In the present invention, preferably, the device further comprises control means that, when the re-sterilization prohibition period is set to ON, can turn the re-sterilization prohibition period to OFF by performing a specific operation or process.

[0020] This configuration provides the following effects. That is, for example, if the disinfecting water spraying device breaks down, the maintenance worker may want to immediately perform a test run of the disinfecting water spraying device. However, in such a case, if the re-sterilization prohibition period is set to ON, it would be difficult to perform the test run (re-execution of the disinfecting water spraying process). In contrast, by performing a specific operation or process, the re-sterilization prohibition period can be set to OFF, making it possible to properly perform the test run, which is highly flexible.

[0021] 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]

DETAILED DESCRIPTION OF THE INVENTION

[0023] Preferred embodiments of the present invention will now be described in detail with reference to the drawings.

[0024] The bathroom sterilization system SY shown in Figures 1 and 2 includes a bathroom drying device A incorporating a sterilizing water sprayer 4. The bathroom drying device A is configured by combining a main body A0 installed on the ceiling 10 of the bathroom 1 in which the bathtub 11 is installed, with 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, the disinfecting water sprayer 4 is an ozone water sprayer that can spray ozone water into the bathroom 1, but it can also spray tap water instead of ozone water.

[0025] Bathroom drying apparatus A is configured to 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, etc. It also includes bathroom remote control 81A and kitchen remote control 81B.

[0026] The main body A0 of the bathroom drying device A includes a blower fan 30 (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 cover these components. It also includes a temperature sensor Sb and a humidity sensor Sc for detecting the room temperature and humidity of the bathroom 1.

[0027] Blower fan 30 draws air from bathroom 1 through air inlet 35a located on the underside of housing 34, and can blow air into bathroom 1 through louver 36 located at the air outlet. The orientation of louver 36 can be changed by a motor (not shown), and the air outlet angle when blowing air can be changed as needed.

[0028] Heat exchanger 31 heats the air drawn into blower fan 30 through air inlet 35a, and heated hot water can be supplied to heat exchanger 31 from water heater 8 as the heating medium. When blower fan 30 is driven and heated hot water is supplied from water heater 8 to heat exchanger 31, the air drawn in through air inlet 35a is heated, and warm air is blown into bathroom 1 through louver 36. When bathroom drying device A is in bathroom drying operation, the warm air blowing and ventilation by ventilation fan 32 are carried out in parallel. 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 36.

[0029] Ventilation fan 32 is a fan that can exhaust 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 35a, 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 of bathroom 1 can be increased or decreased.

[0030] As described above, the disinfecting water sprayer 4 is an apparatus (ozone water sprayer) capable of selectively spraying either ozone water as disinfecting water or tap water as non-disinfecting water. The disinfecting water sprayer 4 includes a water supply pipe 60 that receives tap water from the outside, an on-off valve Va such as an electromagnetic valve provided midway along the water supply pipe 60, a temperature sensor Sa for detecting water temperature, an ozone water generator 42 provided downstream thereof, and a nozzle 43 provided at the end of the water supply pipe 60. The ozone water generator 42 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. The ozone water is sprayed, for example, over almost the entire area of ​​each side wall surface 12 of bathroom 1 except for the area near the upper end, bathtub 11, and almost the entire area of ​​floor surface 13. When the ozone water generating device 42 is turned off, tap water can be sprayed from the nozzle 43.

[0031] Control unit 5 is configured using a microcomputer and other components, and performs operational control and data processing for each component of bathroom drying device A. It also controls disinfectant water sprayer 4 to execute a series of operational processes, including a disinfectant water spraying step of spraying ozone water into bathroom 1, a non-disinfectant water spraying step of spraying tap water into bathroom 1, a disinfectant water rinsing step after the disinfectant water spraying step, and a bathroom drying step after the disinfectant water rinsing step is completed. Details of these processes will be described later.

[0032] The control unit 5 is capable of wireless data communication with the remote control 2 via the communication unit 50. The remote control 2 is, for example, portable, and includes a communication circuit (not shown) for wirelessly communicating with the control unit 5 via the communication unit 50, a control unit 22, a plurality of operation switches 20 for issuing various operation commands, a display unit 21 configured using a liquid crystal display or the like and capable of displaying various types of data, a speaker SP, and the like. The operation switch 20 corresponds to an example of the "operation means" of the present invention, and is capable of turning on the operation (turning on the sterilization treatment switch) to execute the sterilizing water spraying process. However, the "operation means" of the present invention may be means different from the operation switch 20 (for example, an operation switch provided in a location different from the remote control 2).

[0033] The control unit 22 cooperates with the control unit 5 to control the operation of the disinfecting water sprayer 4 and to process various data, the details of which will be described later. One of the control units 22, 5 (control unit 22 in Figs. 1 and 2) is provided with a memory unit 22a, which is capable of storing data relating to the re-disinfection prohibition period P described later. The combination of the control unit 22 equipped with the memory unit 22a and the operation switch 20 corresponds to an example of the "re-sterilization prohibition period changing means" and the "control means" of the present invention.

[0034] Next, an example of the operational processing procedure executed in the bathroom sterilization system SY will be described with reference to the flowchart shown in Figure 3. The operation of the system will also be described.

[0035] In this embodiment, the "sterilization process for bathroom 1" is a process in which each step is performed sequentially, with a set consisting of a non-sterilized water spraying step, a sterilized water spraying step, a sterilized water rinsing step, and a bathroom drying step, as shown in Figure 4(a). The specific content of each step will be described later.

[0036] First, when the user operates the switch using remote control 2 to start the sterilization process of bathroom 1, ventilation fan 32 starts to operate and the non-sterilized water spraying process also starts (S1: YES, S2, S3). As mentioned above, the non-sterilized water is, for example, tap water. The non-sterilizing water spraying process is expected to have a pre-cleaning effect, using tap water to wash away dirt from various parts of the bathroom 1. It is also useful for lowering the room temperature of the bathroom 1 if the room temperature is high. If the room temperature of the bathroom 1 is still 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-sterilizing water spraying process serves to lower the room temperature of the bathroom 1 before the sterilizing water spraying process is executed, thereby eliminating the risk of the ozone gas concentration becoming excessively high. When the room temperature of the bathroom 1 is high, such as immediately after a user has finished bathing, the non-sterilizing water spraying process can be executed to sufficiently lower the room temperature of the bathroom 1.

[0037] The non-sterilized water spraying step ends, for example, when its execution time reaches a predetermined first time (S4: YES, S5). However, instead of this, it may end when the amount of non-sterilized water sprayed reaches a predetermined amount. This method of controlling the end time based on the amount of sprayed water instead of time can also be applied to cases where the sterilized water spraying step ends at the second time in step S8 described below, or where the sterilized water rinsing step ends when the third time in step S11 is reached.

[0038] After the non-sterilized water spraying step is completed, the sterilized water spraying step is started (S6). In this disinfecting water spraying process, ozone water is used to disinfect and clean various parts of bathroom 1. When the disinfecting water spraying process starts, re-disinfection prohibition period P is set to ON (S7). Here, the re-sterilization prohibition period P is a period during which, even if the disinfecting water sprayer 4 is turned on using the operation switch 20, the operation is invalidated and the disinfecting water spraying process is prohibited from being re-executed. This re-sterilization prohibition period P is a period during which, if the disinfecting water spraying process is restarted after the disinfecting water spraying process has been completed or stopped midway, the concentration of ozone gas as free gas in the disinfecting water in the bathroom 1 is expected to exceed a predetermined safety standard concentration UC (e.g., 0.1 ppm). The specific range (length of time, etc.) of the re-sterilization prohibition period P can be determined, for example, based on tests or the results of computer simulations. Furthermore, various factors such as the total amount of ozone gas generated during the sterilization water spraying process, the volume of the bathroom 1, the rate of ozone reduction due to natural decomposition, and the amount of ozone gas emitted from the bathroom 1 due to ventilation can be taken into account based on the amount of ozone generated per unit time by the sterilization water spraying device 4. It may be determined based on the calculation results taking into consideration the above conditions. The sterilized water spraying step ends when the execution time reaches a predetermined second time (S8: YES, S9).

[0039] After the disinfecting water spraying step is completed, the disinfecting water rinsing step is started (S10). This disinfecting water rinsing process is a process in which tap water is sprayed into bathroom 1 from nozzle 43, and by this process, disinfecting water adhering to and remaining in various parts of bathroom 1 is washed away and drained to the outside through a drain outlet (not shown) of bathroom 1. As a result, disinfecting water is prevented from remaining adhering to various parts of bathroom 1 for an unnecessarily long period of time. The disinfecting water rinsing process ends when its execution time reaches a predetermined third time (S11: YES, S12).

[0040] After the disinfectant water rinsing process is completed, a bathroom drying process is initiated, which involves blowing warm air into bathroom 1 (S13). Preferably, the rotation speed of ventilation fan 32 is set higher than the normal speed. This bathroom drying process allows bathroom 1 to be kept dry and not wet with ozone water or tap water. It also promotes the release of ozone gas. This bathroom drying process ends when the humidity in bathroom 1 has decreased to a predetermined value (S14: YES, S15). However, instead, the bathroom drying process can be configured to end when the execution time reaches a predetermined fourth time or when the ventilation volume of bathroom 1 reaches a predetermined value.

[0041] On the other hand, as an example, the re-sterilization prohibition period P is set as a period in which it is set to ON at the start of the sterilization water spraying process (time t2) and set to OFF when a predetermined time T1 has elapsed (time t5) from the end of the bathroom drying process (time t4), as shown in Figure 4(a). In this case, if a switch operation (operation ON operation) is performed to restart the sterilization process at time t10, for example, between the times t4 and t5, the following control is executed. That is, the switch operation is an attempt to restart the sterilization process during the re-sterilization prohibition period P, and this operation is invalid (S16: NO, S21: YES, S22: YES, S23). Therefore, the sterilization process of bathroom 1 is not restarted. This prevents the second sterilization process from being executed shortly after the first sterilization process has finished.

[0042] FIG. 5 shows a comparison example with this embodiment. In this comparison example, at time t10, a switch is operated to restart the sterilization process, starting the second sterilization process. As a result, as shown in FIG. 5(b), the ozone gas concentration in bathroom 1 decreases after the end of the first sterilizing water spraying process at time t3, but then begins to increase after the second sterilization process begins. Therefore, if the ozone gas concentration has not decreased sufficiently at time t10, there is a risk that the ozone gas concentration will subsequently exceed the specified safety standard concentration UC, which is not very healthy for humans. In this embodiment, the bathroom drying process is performed, and although essentially all of the ozone gas should be exhausted from bathroom 1 to the outside during this process, there are cases where the exhaust of ozone gas is insufficient for some reason. In such cases, the ozone gas concentration is more likely to exceed the safety standard concentration UC. In contrast, in the example of this embodiment, as shown in Fig. 4(b), the ozone gas concentration does not increase after time t10, so it is possible to appropriately avoid the problems that occur in the comparative example.

[0043] In step S23, when the retry operation to start sterilization is invalidated, an announcing operation is performed to notify the user of this fact (S24). This announcing operation may be performed by using a predetermined sound (various sound effects, buzzer sound, melody sound, etc.) using the speaker SP of the remote control 2. The notification action is an action of outputting a message (including a button) or a voice message. Of course, instead of or in addition to this, the notification action may be an action of displaying a message on the display unit 21. By performing such a notification action, the user can easily sense that the retry operation to start sterilization has been invalidated, and the risk of mistaking this for a malfunction of the remote control 2 can be eliminated or reduced.

[0044] Thereafter, when the set time of the re-sterilization prohibition period P reaches a predetermined time, the re-sterilization prohibition period P is switched to OFF (S25: YES, S26). When the re-sterilization prohibition period P is switched OFF, the switch operation for starting sterilization is no longer invalidated, so it becomes possible to start the sterilization process again appropriately. This also applies when the set time of the re-sterilization prohibition period P reaches the predetermined time after the bathroom drying process is completed (S16: YES, S26).

[0045] However, unlike the above-described series of operational controls, the disinfectant water spraying process may be interrupted midway due to a switch operation to stop the disinfection process of bathroom 1 during the disinfectant water spraying process (S8: NO, S19: YES, S20). In this case, if a switch operation to resume the disinfection process is subsequently performed during the re-disinfection prohibition period P, the operation is invalidated (S21: YES, S22: YES, S23), and subsequent steps S24 to S26 are the same as those described above. Even if the disinfectant water spraying process is interrupted midway, ozone gas is still being generated in bathroom 1 during the period leading up to the interruption. Therefore, if the disinfectant water spraying process were to be immediately performed again under such circumstances, there is a risk that the ozone gas concentration in bathroom 1 would exceed the safety standard concentration UC. However, this embodiment appropriately avoids this risk. If the operation of step S21 is performed outside the re-sterilization prohibition period P, the non-sterilized water spraying step of the second sterilization process is started (S22: NO, S3).

[0046] The disinfectant water rinsing process and the bathroom drying process may also be interrupted midway, but in this case, the same operational processing as when the disinfectant water spraying process is interrupted midway is executed (S17: YES, S20..., S18: YES, S20...). Therefore, even in these cases, the ozone gas concentration in bathroom 1 can be appropriately prevented or suppressed from exceeding the safety standard concentration UC.

[0047] The bathroom sterilization system SY of this embodiment is capable of changing at least one of the start, end, and length of the re-sterilization prohibition period P, for example, by operating the remote control 2. Note that the start of the re-sterilization prohibition period P is, for example, the start time t2 of the sterilizing water spraying process in the above example, but this may also be the start time t1 of the non-sterilizing water spraying process (when the switch is operated to start the sterilization process of the bathroom 1), as shown in Figure 6(a).

[0048] Furthermore, as shown in Fig. 1(b), the end time t3 of the sterilizing water spraying process can be set as the start time of the re-sterilization prohibition period P. In this case, the period during which the sterilizing water spraying process is performed does not fall under the re-sterilization prohibition period P, but this type of configuration is also possible in the present invention.

[0049] As mentioned above, the end of the re-sterilization prohibition period P can be set to the point when a predetermined time T1 has elapsed since the bathroom drying process, but this time T1 is not particularly limited and can be determined taking various conditions into consideration. Furthermore, the end of the re-sterilization prohibition period P does not necessarily have to be after the bathroom drying process has ended. For example, if exhausting of ozone gas from the bathroom 1 to the outside is almost completely completed during the bathroom drying process, and this can be accurately confirmed by the control unit 22, 5, etc., then the end time t4 of the bathroom drying process can be set to the end of the re-sterilization prohibition period P, as shown in Figure 6(c). More specifically, for example, if it is confirmed that the bathroom is sufficiently ventilated at the time the bathroom drying process has ended, or if a separately installed ventilation system is installed, the end of the re-sterilization prohibition period P can be set to the point when the bathroom drying process has ended. If it is confirmed that the ozone gas concentration measured using the ozone gas concentration sensor has dropped sufficiently, the re-sterilization prohibition period P may end simultaneously with the end of the bathroom drying process.

[0050] In the bathroom sterilization system SY of this embodiment, data related to the setting of the re-sterilization prohibition period P is stored in the memory unit 22a of the control unit 22, and more specifically, the data is stored in, for example, volatile memory (general RAM) of the memory unit 22a. Meanwhile, the power supply to the volatile memory of the memory unit 22a can be interrupted by a maintenance worker operating a specific switch using the remote control 2, or by performing other specific processing (for example, inserting or removing the power plug of the sterilizing water sprayer 4 into a power outlet). This interruption of the power supply can return the re-sterilization prohibition period P to its initial setting of OFF, even if it was previously set to ON.

[0051] This configuration provides the following advantages: For example, if the disinfecting water sprayer 4 breaks down and a maintenance worker repairing it attempts to test run the disinfecting water sprayer 4, it would be difficult to do so if the timing falls within the re-sterilization prohibition period P. However, with the configuration described above, the re-sterilization prohibition period P can be set to OFF by interrupting the power supply to the memory of the storage unit 22a, which conveniently enables the disinfecting water sprayer 4 to be properly test run. Unlike the above, the data regarding the re-sterilization prohibition period P may be stored in a non-volatile memory provided in the storage unit 22a.

[0052] 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 designed and modified within the intended scope of the present invention.

[0053] In the above-described embodiment, when the disinfecting water spraying step is performed, the non-disinfecting water spraying step is performed prior to the disinfecting water spraying step, but the present invention is not limited to this, and the disinfecting water spraying step may be performed without the non-disinfecting water spraying step. Furthermore, although it is preferable that the disinfecting water rinsing step and the bathroom drying step be both performed after the disinfecting water spraying step, it is also possible to omit either or both of these steps.

[0054] 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.

[0055] In the above-described embodiment, the disinfecting water spraying device is configured to also function as a non-disinfecting water spraying device, but the present invention is not limited to this. A non-disinfecting water spraying device may be provided separately from the disinfecting water spraying device. The disinfecting water spraying device may be configured to spray disinfecting water into a bathroom, and the specific method for generating disinfecting water or the concentration of specific components in the generated disinfecting water are not limited. The number of nozzles for spraying disinfecting water is not limited to one, and multiple nozzles may be used, and the specific number is not important. Furthermore, disinfecting water or non-disinfecting water may be sprayed intermittently, for example, at a predetermined short interval, instead of continuously.

[0056] In the above-described embodiment, the disinfecting water spraying device is incorporated into a bathroom drying device equipped with a blower fan and a ventilation fan, but the present invention is not limited to this, and it is also possible to configure the device so that it is not incorporated into a bathroom drying device.
