Description

  TECHNICAL FIELD The present invention relates to a mold generation preventing device that suppresses the generation of mold in a bathroom, and more particularly to a mold generation preventing apparatus having a dehumidifying function for reducing the relative humidity in a bathroom.

  In general households, bathroom dryers installed in bathrooms are becoming popular. By heating the bathroom, for example, even when the outside air temperature is low, such as in winter, a rapid change in temperature can be suppressed and comfortable bathing can be performed. Also, by ventilating and flowing cool air, you can enjoy a comfortable bathing in the summer and prevent mold in the bathroom. Furthermore, the clothes can be washed at any time regardless of the weather by drying in the bathroom.

In consideration of the fact that the bathroom is originally a high-humidity space, more efficiently drying clothes and preventing mold, it is desirable to add a dehumidifying function to the bathroom dryer. As a means for realizing such a dehumidifying function, for example, a technique has been proposed in which moisture in the bathroom is adsorbed using an adsorbent such as zeolite or silica gel and regenerated and discharged out of the bathroom (for example, Patent Documents). 1 and 2).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a bathroom 400 to which a mold generation preventing apparatus 1 according to the present invention is applied. FIGS. 2 and 4 are sectional views illustrating the configuration of the mold generation preventing apparatus 1. FIG. 3 is a mold generating apparatus 1 according to the present invention. It is the top view seen from the bottom at the time of attaching a main body to the bathroom 400 ceiling.

  As shown in FIG. 1, a resin bathroom 400 is provided with a bathtub 5 and a floor panel 7 serving as a washing place. The mold prevention device 1 according to the present invention is attached to the ceiling of a bathroom 400.

As shown in FIGS. 2 and 4, the fungus generation preventing apparatus 1 according to the present invention has a main body formed in a rectangular parallelepiped shape, with a circulation inlet 110, a circulation outlet 120, and a regeneration inlet on the lower surface. An opening is formed as 210. Further, a regeneration exhaust port 220 for connecting an exhaust duct connecting the outdoor unit and the main body is formed above the side surface of the main body of the apparatus 1.
In the apparatus 1 main body, a circulation path 100 formed so that air in the bathroom 400 sucked from the circulation inlet 110 is exhausted from the circulation outlet 120 into the bathroom 400 again, and a regeneration inlet And a delivery path 200 formed so that the air in the bathroom 400 sucked in from 210 is exhausted from the regeneration exhaust port 220 to the outdoors.

The circulation path 100 and the delivery path 200 are each partitioned by a partition wall 15, and a through hole that penetrates the circulation path 100 and the delivery path 200 is formed in a part of the partition wall 15, and the moisture adsorption member 10 circulates in the through hole. One is placed so as to extend both within the route 100 and within the delivery route 200.
The moisture adsorbing member 10 is formed of a zeolite or silica gel into a disk shape, and is a porous body such as a honeycomb structure in order to increase the adsorption surface area.

  The moisture adsorbing member 10 circulates in the circulation path 100 and the delivery path 200 by slowly rotating at a constant speed with a substantially center as a rotation axis (not shown). That is, the moisture adsorbing portion that has adsorbed moisture in the circulation path 100 rotates slowly, and thus comes into the delivery path 200 after a predetermined time.

A first blower 20 (fan) is disposed downstream of the moisture adsorbing member 10 in the circulation path 100, and the air in the bathroom 400 is sucked from the circulation inlet 110 and passes through the moisture adsorbing member 10. An air flow is formed so that air is blown out from the circulation outlet 120.
In addition, a second blower 50 (fan) is disposed on the downstream side of the moisture adsorbing member 10 in the delivery path 200, and the air in the bathroom 400 is sucked from the regeneration inlet 210 to remove the moisture adsorbing member 10. An air flow for discharging the passed air from the regeneration exhaust port 220 is formed.
Here, the air volume created by the first blower 20 is larger than the volume created by the second blower 50.

  A heating device 40 is attached in the vicinity of the upstream side of the moisture adsorbing member 10 in the regeneration path. In order to desorb the moisture adsorbed on the moisture adsorbing member 10, the heating device 40 heats the air taken from the regeneration inlet 210 and applies the heated air to the moisture adsorbing member 10 to remove the moisture. Acts to desorb.

  The heating device 40 uses a nichrome wire heater, a PTC heater, or the like, but is intended to desorb moisture from the moisture adsorbing member 10 and therefore needs to be heated to a high temperature. Cost.

  As shown in FIG. 3, humidity detection means 24 for detecting the relative humidity in the bathroom 400 is located at a position away from the circulation inlet 110, the circulation outlet, and the regeneration inlet 210 on the bottom surface of the main body of the apparatus 1. It is attached. The humidity detecting means 24 is accommodated in a small box, and a dew condensation preventing heating device (heater) for preventing the humidity detecting means 24 from condensing is also accommodated near the humidity detecting means 24 in the box.

  Further, a cover 2 (not shown) for making the appearance flat is attached to the lower part of the main body of the apparatus 1. The cover 2 has a circulation inlet 110, a circulation outlet, and a regeneration inlet. An introduction channel 300 connected to 210 is formed.

  Although details will be described in detail later, the mold prevention device 1 of the present invention feeds back the relative humidity detected by the humidity detecting means 24 to a control device built in the device 1, thereby rotating the moisture adsorbing member 10. The operation of the first blowing device 20, the second blowing device 50, and the heating device 40 is controlled.

  Here, the significance of attaching the humidity detecting means 24 to the above-described position will be described. It is important for the relative humidity detected by the humidity detecting means 24 to accurately grasp the relative humidity in the bathroom 400, particularly in the vicinity of the floor surface 7 in the bathroom 400 where residual water tends to remain and mold tends to propagate. By accurately detecting the relative humidity of the place where mold in the bathroom 400 is likely to propagate, it becomes unnecessary to over-operate more than necessary within the range where mold does not propagate. In particular, when the device 1 is operated, it is necessary to start the heating device 40 that consumes power, so over-specification operation is an important technical issue that must be solved in the present age when energy saving has become a social problem. is there.

First, when the humidity detecting means 24 is disposed downstream of the moisture adsorbing member 10 in the circulation path 100, the relative humidity of the air dehumidified by the moisture adsorbing member 10 is detected. This is not preferable because it may be detected lower than a place where breeding is easy.
In addition, when the humidity detection means 24 is arranged on the downstream side of the moisture adsorbing member 10 in the delivery path 200, the relative humidity of the air containing the moisture desorbed from the moisture adsorbing member 10 is detected by the heating device 40. This is not preferable because mold in the bathroom 400 may be detected higher than a place where it is easy to breed.
Next, when the humidity detection means 24 is arranged upstream of the moisture adsorbing member 10 in the circulation path 100, the air flow in the path is increased by the first blower 20, so the humidity detection means 24 is accommodated. This is not preferable because it causes the temperature of the dew condensation prevention heating device 40 in the box to be cooled, and the humidity detection means 24 is dewed, so that mold in the bathroom 400 may be detected higher than a place where it can easily propagate.
Similarly, even when the humidity detection unit 24 is arranged on the downstream side of the moisture adsorption member 10 in the delivery path 200, the problem when the humidity detection unit 24 is arranged on the upstream side of the moisture adsorption member 10 in the circulation path 100. It is common and not preferable.

  In view of the above-described problems, the humidity detecting means 24 in the present embodiment is attached to the bottom surface of the main body of the apparatus 1 at a position away from the circulation inlet 110, the circulation outlet, and the regeneration inlet 210. It is possible to detect the relative humidity close to the place where mold in the bathroom 400 is likely to breed, and it is not necessary to overdrive, so energy saving can be achieved.

  Next, the significance of disposing the second blower 50 on the downstream side of the moisture adsorbing member 10 in the delivery path 200 will be described. When the second blower device 50 is arranged upstream of the moisture adsorbing member 10 in the delivery path 200, the air acts in a direction to push out the moisture adsorbing member 10. Since the main body of the apparatus 1 is attached to a limited space in the ceiling part of the bathroom 400, it is desired that the apparatus 1 is designed to have a compact size. Therefore, the distance which connects the 2nd air blower 50 and the water | moisture-content adsorption | suction member 10 cannot be earned greatly. In such a state, when air is applied to the moisture adsorbing member 10 by the second air blower, spots are formed in a portion through which the air passes. That is, there is a problem that moisture is difficult to desorb at locations where heated air in the delivery path 200 is difficult to contact.

  In order to make full use of the adsorption capacity of the entire moisture adsorbing member 10, it is preferable that the moisture of the moisture adsorbing material is evenly desorbed (regeneration of the moisture adsorbing member 10) in the delivery path 200. In this embodiment, since air is sucked from the downstream side of the moisture adsorbing member 10, the air uniformly passes through the moisture adsorbing member 10 facing the delivery path 200, so that moisture is evenly removed. Can be separated. Therefore, since the adsorption capacity of the moisture adsorbing member 10 can be fully utilized at all times, the energy saving effect during the dehumidifying operation is great.

  The above-described positional relationship between the moisture adsorbing member 10 and the blower in the path is the same for the moisture adsorbing member 10 facing the circulation path 100 and the first blower 20.

  Further, a ventilation port 130 is formed on the downstream side of the moisture adsorbing member 10 and the first blower in the circulation path 100, to which a ventilation path that connects the outdoors and the main body of the apparatus 1 is connected. A damper 70 that can be opened and closed by a command from the control device is attached to the ventilation port 130. During the ventilation operation, the damper 70 is opened, and the air in the bathroom 400 sucked from the first blower device 20 is taken. The air is exhausted from the ventilation port 130 to the outside through the circulation inlet 110 and the moisture adsorbing member 10. At the same time, when a command for ventilation operation is input from the control device, the second blower device 50 is also activated, and the air in the bathroom 400 is exhausted from the regeneration exhaust port 220 through the regeneration intake port 210 and the moisture adsorbing member 10. On the other hand, during the dehumidifying operation (except during the ventilation operation), the damper 70 is in a closed state.

  Next, a control sequence when the mold generation preventing operation of the mold generating apparatus 1 in the configuration of this embodiment is operated will be described with reference to FIG.

Here, in this embodiment, the first predetermined value is 51% (relative humidity), and the second predetermined value is 60% (relative humidity).
First, when the user turns on the mold prevention operation mode switch with the remote control of the mold generating apparatus 1 installed on the inner wall of the bathroom next to the bathroom 400 (S1), a timer in a reset state built in the control apparatus. Is started (S2), the damper 70 is opened, and the first blower 20 and the second blower 50 are driven to execute the ventilation operation mode (S3). After the ventilation mode is executed for a predetermined time (30 minutes) (S4), the damper 70 is closed, the first blower 20 and the second blower 50 are stopped, and the ventilation mode is executed. (S5). At this time, the timer count is continued.

  When the ventilation operation is completed, the dehumidifying operation mode is subsequently entered. The dehumidifying operation mode is continued until the elapsed time from the start of the ventilation operation mode counted by a timer reaches 4 hours (S6). First, the first air blower 20, the second air blower 50, the heating device 40, and the moisture adsorbent are driven to perform dehumidification in the bathroom 400 (S7). The relative humidity in the bathroom 400 is constantly monitored by the humidity detecting means 24, and the dehumidifying operation mode is continuously executed until the relative humidity detected by the humidity detecting means 24 becomes 51% or less.

  In the dehumidifying operation mode, when the relative humidity detected by the humidity detecting means 24 becomes 51% or less (S8), the operation of the heating device 40 and the second blower device 50 is stopped, and the first blower device 20 and the moisture adsorbing member. The rotation drive of 10 continues (S9).

At this time, the meaning of continuing the rotational drive of the first blower 20 and the moisture adsorbing member 10 even after the relative humidity becomes 51% or less will be described below.
Dehumidification in the bathroom 400 in the present apparatus 1 is achieved by driving the first air blower 20 to allow moisture containing air to pass through the moisture adsorbing member 10 and adsorbing moisture in the air to the moisture adsorbing member 10. It is a mechanism to dry. That is, when the moisture adsorption capacity of the moisture adsorption member 10 is not saturated, the dehumidification in the bathroom 400 is still possible.

  Here, the moisture adsorbing member 10 immediately after the relative humidity becomes 51% or less (immediately after the interruption of the heating regeneration operation) has not yet reached a saturated state and has a moisture adsorbing capability. Therefore, even after the relative humidity becomes 51% or less, the adsorption capacity of the entire moisture adsorbing member 10 can be fully utilized by continuing the rotational drive of the first blower 20 and the moisture adsorbing member 10. It becomes. In the dehumidifying operation of this mold prevention device 1, the device that consumes the most power is the heating device 40. Even after the operation of the heating device 40 is stopped as in this embodiment, the dehumidifying operation (low humidity in the bathroom 400) is further performed. It is possible to dehumidify the interior of the bathroom 400 to a low humidity level where it is difficult for mold to occur by maximizing the adsorption capacity of the moisture adsorbent with low power consumption. At this time, since the second blower 50 is disposed on the downstream side of the moisture adsorbing member 10 in the delivery path 200, the refreshed (regenerated) area of the moisture adsorbing member 10 is increased. Therefore, the amount of decrease in humidity increases when the first blower 20 and the moisture adsorbent are rotationally driven with the heating device 40 and the second blower 50 stopped. Further, since the accuracy of the detection value detected by the humidity detecting means 24 is high, the dehumidifying operation necessary for preventing the occurrence of mold can be performed efficiently and efficiently, so that it is not necessary to perform an excessive operation and energy consumption can be saved.

  In addition, the significance of stopping the operation of the second blower at this time will be described. The mold generation prevention device 1 is configured such that the air in the bathroom 400 is discharged to the outside via the delivery path 200 by activating the second blower device 50. That is, by driving the second blower 50, the warm air in the bathroom 400 will be discharged outdoors. When the dehumidifying request is made, it is not preferable that the temperature in the bathroom 400 decreases because evaporation of residual water on the floor surface 7 and the like where mold tends to occur is slowed down. Further, when the air in the bathroom 400 is discharged to the outside, the air flows into the bathroom 400 from the louver provided at the lower part of the door of the bathroom 400 or the gap of the bathroom 400 window. Since the relative humidity inside the house is high during periods when the dehumidifying operation is most necessary during the rainy season or winter, there is a problem that the relative humidity inside the bathroom 400 increases due to the inflow of air outside the bathroom 400. Absent.

  According to this embodiment, since the second blower 50 is stopped after the relative humidity detected by the humidity detecting unit 24 is 51% or less, the temperature and the relative humidity in the bathroom 400 are reduced. Therefore, the interior of the bathroom 400 can be efficiently transferred to a desired low humidity environment in a short time.

  There is a correlation between mold suppression and relative humidity, and it is generally known that mold is suppressed and killed in a shorter time as the humidity is lowered. The ability to reduce the humidity by maximizing the adsorption capacity of the moisture adsorbing member 10 with low power consumption as in this embodiment has a great contribution in the present age when energy saving has become a social problem.

Again, the continuation of the control sequence after S9 of this mold | generation prevention apparatus 1 is demonstrated.
While stopping the operation of the heating device 40 and the second air blower 50, the first air blower 20 and the moisture adsorbing member 10 are continuously driven to rotate (S9), and the adsorbing capacity of the water adsorbing member 10 is also saturated. If it will be in the state, the residual water in the bathroom 400 floor 7 and the bathtub 5 evaporates, and the relative humidity detected by the humidity detection means 24 may eventually become 60% or more again (S10). In such a state, the heating device 40 and the second blower device 50 are restarted again. That is, the dehumidifying operation for operating the rotational drive of the first air blower 20, the second air blower 50, the heating device 40, and the moisture adsorbing member 10 is executed again (S7).

  After such intermittent operation of S6 to S10 is continued for a preset time (4 hours), the mold generation prevention operation of the mold generation prevention device 1 is automatically stopped.

  FIG. 9 shows a graph showing a change in relative humidity when the mold generation preventing apparatus 1 is operated in the mold generation preventing apparatus 1 in the configuration of the first embodiment described above. Even after the relative humidity becomes 51% or less as in the present embodiment, the rotation of the first air blower 20 and the moisture adsorbing member 10 is continued, so that the heating device 40 is operated at a relative humidity of 51%. It can be seen that the relative humidity has dropped to nearly 45% despite being stopped.

  Next, a second embodiment of the control sequence in the mold prevention device 1 will be described with reference to FIG. Here, only the differences of the second embodiment of the present invention from the first embodiment will be described, and the same components are denoted by the same reference numerals and description thereof is omitted.

  First, after the steps S1 to S8 are performed, when the relative humidity detected by the humidity detecting means 24 becomes 51% or less, the counting of the second timer in the reset state built in the control device is started (S21). ). At the same time, the operation of the heating device 40 and the second air blower 50 is stopped, and the rotational drive of the first air blower 20 and the moisture adsorbing member 10 is continued (S22). The rotational drive of the first air blower 20 and the moisture adsorbing member 10 is stopped when the counter of the second timer counts 20 minutes (S23), and when the relative humidity in the bathroom 400 becomes 60% or more again (S24). Then, the dehumidifying operation mode in which the operation of rotational driving of the first air blower 20, the second air blower 50, the heating device 40, and the moisture adsorbing member 10 is executed again is resumed (S6).

  Here, after the relative humidity becomes 51% or less, the significance of stopping the rotational drive of the first air blower 20 and the moisture adsorbing member 10 when the second timer counts 20 minutes will be described.

  As described in the above-described embodiment, the moisture adsorbing member 10 immediately after the relative humidity becomes 51% or less still retains the moisture adsorbing ability, and the first air blower 20 and the moisture adsorbing member 10 are retained. The air in the bathroom 400 can be further dehumidified by rotationally driving. However, the adsorption capacity of the moisture adsorbing member 10 is saturated because heating regeneration is not performed. After the saturated state is reached, dehumidification cannot be achieved even if moisture containing air is passed through the moisture adsorbing member 10. In other words, after the moisture adsorbing member 10 is saturated, the first air blower 20 and the rotation driving of the moisture adsorbing member do not contribute to dehumidification in the bathroom 400. It is preferable to set so that energy consumption required for rotational driving of the first blower 20 and the moisture adsorbing member 10 can be saved.

  Next, a third embodiment of the control sequence in the mold prevention device 1 will be described with reference to FIG. Here, only the points of the third embodiment of the present invention that are different from the first and second embodiments will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted.

  First, after performing the steps S1 to S8, when the relative humidity detected by the humidity detecting means 24 is 51% or less, the heating device 40 and the second blower device 50 are stopped and the first blower device is used. The rotational drive of 20 and the moisture adsorbing member 10 continues (S31). The rotational driving of the first blower 20 and the moisture adsorbing member 10 is stopped when the relative humidity detected by the humidity detecting means 24 is less than 45% (S32), and the relative humidity in the bathroom 400 is again 60%. If it becomes above (S33), the dehumidification operation mode which performs again the driving | operation of the rotational drive of the 1st air blower 20, the 2nd air blower 50, the heating apparatus 40, and the water | moisture-content adsorption | suction member 10 will restart (S7).

  Here, after the relative humidity becomes 51% or less, when the relative humidity detected by the humidity detecting means 24 becomes less than 45%, the rotational driving of the first blower 20 and the moisture adsorbing member 10 is stopped. Explain the significance of this.

  As described in the above-described embodiment, the moisture adsorbing member 10 immediately after the relative humidity becomes 51% or less retains the moisture adsorbing ability, and the first air blower 20 and the moisture adsorbing member 10 are connected. By rotating and driving, the air in the bathroom 400 can be further dehumidified. However, the adsorption capacity of the moisture adsorbing member 10 is saturated because heating regeneration is not performed. After the saturated state is reached, dehumidification cannot be achieved even if moisture containing air is passed through the moisture adsorbing member 10. That is, after the moisture adsorbing member 10 is saturated, the rotational drive of the first air blower 20 and the moisture adsorbing member 10 does not contribute to dehumidification in the bathroom 400. It is preferable to set the relative humidity so that energy consumption required for rotational driving of the first blower 20 and the moisture adsorbing member 10 can be saved.

  Next, a fourth embodiment of the control sequence in the mold prevention device 1 will be described with reference to FIG. Here, only differences from the first, second, and third embodiments of the fourth embodiment of the present invention will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted.

  First, after performing the steps S1 to S8, when the relative humidity detected by the humidity detecting means 24 is 51% or less, the heating device 40 and the second blower device 50 are stopped and the first blower device is used. The rotational drive of 20 and the moisture adsorbing member 10 continues (S41). In the rotational driving of the first blower 20 and the moisture adsorbing member 10, the amount of decrease in relative humidity per unit time (relative humidity decrease rate) detected by the humidity detecting means 24 is less than minus 0.5% / min. When the relative humidity in the bathroom 400 reaches 60% or more again (S43), the first blower 20, the second blower 50, the heating device 40, and the moisture adsorbing member 10 are rotationally driven. The dehumidifying operation mode for executing the operation again is resumed (S7).

  Here, after the relative humidity becomes 51% or less, the first blower device at the stage where the amount of decrease in the relative humidity detected by the humidity detecting means 24 per unit time is less than minus 0.5% / min. 20 and the significance of stopping the rotational drive of the moisture adsorbing member 10 will be described.

  As described in the above-described embodiment, the moisture adsorbing member 10 immediately after the relative humidity becomes 51% or less retains the moisture adsorbing ability, and the first air blower 20 and the moisture adsorbing member 10 are connected. By rotating and driving, the air in the bathroom 400 can be further dehumidified. However, the adsorption capacity of the moisture adsorbing member 10 is saturated because heating regeneration is not performed. After the saturated state is reached, dehumidification cannot be achieved even if moisture containing air is passed through the moisture adsorbing member 10. That is, after the moisture adsorbing member 10 is saturated, the rotational drive of the first air blower 20 and the moisture adsorbing member 10 does not contribute to dehumidification in the bathroom 400, so the amount of decrease in relative humidity per unit time is reduced. By monitoring, the current adsorption capacity of the moisture adsorbing member 10 can be grasped, and energy consumption required for rotational driving of the first blower 20 and the moisture adsorbing member 10 can be saved, which is preferable.

  Next, another embodiment of the mounting position of the humidity detecting means 24 will be described as a fifth embodiment of the present mold prevention device 1.

  In the present embodiment, the humidity detecting means 24 is attached to a remote controller that is configured separately from the main body 1 of the mold prevention device 1. The remote control is further provided with a dew condensation preventing heating device 40 for preventing dew condensation between the transmitting antenna and the humidity detecting means 24, and is fixed to the inner wall surface of the bathroom 400 so that the relative humidity in the bathroom 400 can be detected. ing. Note that when the humidity detection information is transmitted from the remote controller, it may be wireless or wired.

  Relative humidity information in the bathroom 400 detected by the humidity detecting means 24 is transmitted from the transmission antenna of the remote control to the receiving unit of the mold generating device 1 body, and the relative humidity information received by the receiving unit is built in the device 1 body. The control device controls the rotational drive of the first blower device 20, the second blower device 50, the heating device 40, and the moisture adsorbing member 10 based on the relative humidity detection information.

  In the embodiment as described above, a general drying device such as a heating device (heater) or a blower device (fan) may be used as the dew condensation prevention unit for preventing the humidity detection unit 24 from dew condensation.

  Next, another embodiment other than the embodiments described above will be described. In the embodiment described so far, after the steps S1 to S8 are performed, the operation of the heating device 40 and the second blower device 50 is stopped when the relative humidity detected by the humidity detecting unit 24 is 51% or less. At the same time, the rotational drive of both the first air blower 20 and the moisture adsorbing member 10 has been continued. At this time, the rotational drive of the heating device 40, the second air blower 50, and the moisture adsorbing member 10 is stopped. At the same time, only the operation of the first blower 20 may be continued. Even in this case, since the operation of the first air blower 20 is continued, the moisture adsorption capability of the moisture adsorption member 10 facing the circulation path 100 can be used effectively, so the moisture adsorption member can be used with low power consumption. The maximum adsorption capacity of 10 can be used to reduce the humidity.

  Moreover, after performing the process of S1-S8, when the relative humidity which the humidity detection means 24 detects is 51% or less, while stopping the driving | operation of the heating apparatus 40 and the 2nd air blower 50, the 1st air blower The operation of 20 may be continued, and the rotation of the moisture adsorbing member 10 may be intermittently driven so that the inside of the delivery path 200 and the inside of the circulation path 100 are alternately switched periodically.

  Moreover, in the Example mentioned above, when switching from ventilation operation mode to dehumidification operation mode, although the operation | movement of the 1st air blower 20 and the 2nd air blower 50 was once stopped, You may make it transfer to the following process, with the driving | operation of the 2nd air blower 50 continued.

  Further, in the embodiment described above, the present mold prevention device 1 is attached to the ceiling of the bathroom 400, but it may be attached above the wall surface of the bathroom 400.
