Description

  Aspects of the present invention generally relate to a bathroom dryer.

  When the user takes a bath, water drops adhere to the bathroom floor and side walls. This water droplet contains dirt such as detergent and human body sebum. Such dirt is a nutrient for mold. Also, the bathroom is often an environment sufficient for mold to grow in terms of temperature and humidity.

  For example, the washroom floor is considered to be a portion where water droplets are easily attached in the bathroom and mold is likely to occur. On the other hand, the material of the washing floor is changed and the shape of the washing floor is devised. Thereby, drainage can be improved and generation | occurrence | production of mold | fungi can be suppressed. Moreover, a bathroom drying device for drying the inside of the bathroom may be installed in the bathroom. This bathroom drying device promotes drying by, for example, sending air to a washroom floor that is considered to be easily soiled. Thereby, generation | occurrence | production of mold | fungi can be suppressed.

Japanese Patent Laid-Open No. 9-72559

  When the user takes a bath, steam (water vapor) is generated in the bathroom. This vapor also contains dirt such as detergents and human sebum. When such steam reaches the ceiling of the bathroom, condensation occurs on the ceiling due to the difference between the temperature of the steam and the temperature of the ceiling. That is, the water droplets containing dirt adhere not only to the washing floor and the side walls, but also to the ceiling surface. For this reason, mold may occur on the ceiling. In addition, when mold occurs on the ceiling, mold may spread throughout the bathroom due to spores released by the mold. On the other hand, since the conventional bathroom drying apparatus dries the washing floor and the side wall considered to be easily soiled, it is difficult to suppress the occurrence of mold on the ceiling.

  This invention is made | formed based on recognition of this subject, and it aims at providing the bathroom drying apparatus which can suppress generation | occurrence | production of the mold | fungi in a ceiling.

1st invention dries the bathroom which has a ceiling, It is the bathroom drying apparatus installed in the said ceiling, Comprising: The inlet which sucks in air, and the blower outlet which blows off the air suck | inhaled from the said inlet into the said bathroom And a control unit that controls the air blowing operation that blows air from the air outlet toward the ceiling and forms an air flow along the ceiling, and the air blowing operation is performed. The component of water vapor generated in the bathroom out of the absolute humidity of the air blown out from the outlet is less than the component of water vapor generated in the bathroom out of the absolute humidity of the air in the bathroom. This is a bathroom drying device.

According to this bathroom drying apparatus, air is blown out from the air outlet toward the ceiling in the air blowing operation, and an air flow is formed along the ceiling. In this air, the amount of water vapor generated in the bathroom is small. As a result, even when water vapor containing sebum or the like is generated in the bathroom during bathing by the user, the air blown from the outlet covers the ceiling, so that the water vapor generated in the bathroom is applied to the ceiling. The amount reached can be reduced. Further, even when water droplets adhere to the ceiling due to condensation, dirt on the ceiling can be suppressed because there is little sebum contained in the water droplets. Therefore, generation | occurrence | production of the mold resulting from the stain | pollution | contamination of a ceiling can be suppressed. Furthermore, since mold spores can be prevented from scattering from the ceiling to the entire bathroom, generation of mold in the entire bathroom can be suppressed.

  A second invention further comprises a dehumidifying part provided in the air passage in the first invention, wherein the suction port sucks air from inside the bathroom during the air blowing operation, and the air outlet The bathroom drying apparatus is characterized in that air sucked from the bathroom and dehumidified by the dehumidifying unit is blown out.

  According to this bathroom drying apparatus, the air in the bathroom is sucked from the suction port, dehumidified, and then blown out into the bathroom. That is, the bathroom drying device circulates the air in the bathroom. When air is taken in from outside the bathroom, the temperature of the air taken in varies depending on the season. For example, in winter, the user may feel cold while taking a bath because the temperature of the outside air is low. On the other hand, by circulating the air in the bathroom, the difference between the temperature of the air blown from the outlet and the temperature in the bathroom can be reduced. Thereby, for example, the cold felt by the user can be suppressed, and condensation on the ceiling of the bathroom can be suppressed.

  In a third aspect based on the first aspect, the suction port sucks air from outside the bathroom during the air blowing operation, and the blowout port blows air sucked from outside the bathroom into the bathroom. This is a bathroom drying device.

  According to this bathroom drying apparatus, air is sucked from outside the bathroom that does not contain water vapor generated in the bathroom. Thereby, the quantity of the water vapor | steam generate | occur | produced in the bathroom in the air which blows off along the ceiling of a bathroom can further be reduced. Therefore, the occurrence of mold can be further suppressed.

  4th invention is further provided with the temperature detection means which detects the temperature in the said bathroom in any 1st-3rd invention, The rise per unit time of the temperature detected by the said temperature detection means The bathroom drying apparatus is characterized in that the air blowing operation is started when a predetermined value or more is reached.

  According to this bathroom drying apparatus, for example, when the temperature in the bathroom rises by a predetermined value or more per unit time due to a bathing action such as taking a shower, the air blowing operation is started. When a user takes a bathing action such as taking a shower, water vapor is generated in the bathroom, and the temperature in the bathroom rises. For this reason, when the temperature in the bathroom rises by a predetermined value or more per unit time, it is considered that condensation is likely to occur in the bathroom. Therefore, by performing the air blowing operation when the temperature in the bathroom rises by a predetermined value or more per unit time, it is possible to suppress water droplets including dirt from adhering to the ceiling. There is no need for the user to start operation of the bathroom drying device every time the user takes a bath.

  5th invention is further equipped with the heating part provided in the said air path in any one 1st-4th invention, The said blower outlet was heated by the said heating part in the said ventilation operation. It is a bathroom drying apparatus characterized by blowing out air.

  According to this bathroom drying apparatus, the ceiling of a bathroom can be warmed by blowing heated air. Thereby, even if it is a case where water vapor | steam reaches | attains a ceiling, the difference of the temperature of water vapor | steam and the temperature of a ceiling can be made small, and it can suppress that dew condensation arises on a ceiling.

  The sixth invention is the invention according to any one of the first to fifth inventions, wherein after the start of the air blowing operation, the temperature detected by the temperature detecting means for detecting the temperature in the bathroom is lowered by a predetermined value or more. It is a bathroom drying device characterized by continuing the air blowing operation.

  According to this bathroom drying apparatus, even when a bathing action such as taking a shower is completed, air is blown out toward the ceiling until the temperature in the bathroom decreases by a predetermined value or more. Even after the completion of the bathing action, water vapor generated in the bathroom due to the bathing action may remain in the bathroom. By continuing to blow out air until the temperature in the bathroom decreases, it is possible to suppress the water vapor remaining in the bathroom from reaching the ceiling. Therefore, it is possible to suppress water droplets containing dirt from adhering to the ceiling due to condensation.

  According to the aspect of the present invention, there is provided a bathroom drying apparatus capable of suppressing the occurrence of mold on the ceiling.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic perspective view showing a bathroom in which a bathroom drying apparatus according to an embodiment of the present invention is installed.
As shown in FIG. 1, the bathroom drying apparatus 100 according to this embodiment is installed in a bathroom 10.
The bathroom 10 includes a washroom floor 13, a side wall 12, and a ceiling 11. The bathroom 10 is a space defined by the four wall surfaces of the side wall 12, the ceiling 11, and the floor surface. Furthermore, the bathroom 10 has a bathtub 14 provided adjacent to the washing floor 13.
The bathroom drying apparatus 100 is installed on the ceiling 11 of such a bathroom 10, for example. For example, the bathroom drying apparatus 100 is located above the bathtub 14.

FIG. 2 is a schematic diagram illustrating a main configuration of the bathroom drying apparatus according to the present embodiment. In FIG. 2, the air path system and the electrical system are shown together.
FIG. 3 is a schematic cross-sectional view illustrating the bathroom drying apparatus according to this embodiment.
FIG. 4 is a block diagram illustrating a bathroom drying apparatus according to this embodiment.

  As illustrated in FIG. 2, the bathroom drying apparatus 100 includes an air path 116, a heating unit 118, a control unit 120, a fan 122, and a dehumidifying unit 123. The air passage 116 has a suction port 112 (first suction part 112a) and a blower port 114. The bathroom drying apparatus 100 further includes temperature detection means 125 (see FIGS. 3 and 4). Moreover, the blower outlet 114 may have the movable part 124 (electric louver).

  The bathroom drying apparatus 100 is, for example, a built-in (ceiling embedded) type. That is, as shown in FIG. 3, the upper part of the bathroom drying apparatus 100 is located above the ceiling 11 and is disposed outside the bathroom 10 when installed on the ceiling 11. The lower part of the bathroom drying apparatus 100 is located below the ceiling 11 and is disposed inside the bathroom 10.

  The air path 116 shown in FIG. 2 is an air passage provided inside the housing 111 of the bathroom drying apparatus 100. The air passage 116 connects the inlet 112 and the outlet 114.

  The blower outlet 114 and the suction inlet 112 are each connected to the bathroom 10. As a result, the air passage 116 communicates with the interior of the bathroom 10 via the inlet 112 (first inlet 112a) and the outlet 114.

  The fan 122 is provided inside the air passage 116. The fan 122 includes, for example, a motor. When the fan 122 (motor) is energized, the motor rotates and the fan 122 is driven. As a result, the fan 122 generates an air flow in the air passage 116.

  As shown by the arrow A1 in FIGS. 2 and 3, the suction port 112 sucks air in the bathroom according to the operation of the fan 122. The sucked air passes through the air passage 116 and is guided to the air outlet 114 by the fan 122. As shown by an arrow A <b> 2 shown in FIGS. 2 and 3, the air outlet 114 blows out air sucked by the air inlet 112 into the bathroom 10.

  The movable part 124 (electric louver) changes the direction of the air blown out from the blower outlet 114. By changing the angle of the louver relative to the bathroom 10, the direction in which air is blown out can be changed. Note that the electric louver is not necessarily provided.

  The heating unit 118 is provided inside the air path 116. In the example of FIG. 2, the heating unit 118 is located between the fan 122 and the outlet 114 on the air path 116. The heating unit 118 is, for example, an electric heater. When the heating unit 118 is energized, the heating unit 118 heats the air in the air passage 116. That is, the heating unit 118 heats the air sucked by the suction port 112. Thereby, the heated air can be blown out from the blower outlet 114. Note that the heating unit 118 is not necessarily provided.

  The dehumidifying unit 123 is provided inside the air passage 116. In the example of FIG. 2, the dehumidifying unit 123 is located between the fan 122 and the suction port 112 on the air path 116. The dehumidifying unit 123 dehumidifies the air sucked from the suction port 112.

  The dehumidifying part 123 is a cooling part provided on the air path 116, for example. The cooling unit performs dehumidification by condensing water vapor contained in the air. For example, a member such as a metal is disposed as the dehumidifying unit 123. For example, a plurality of metal plates can be used for the dehumidifying unit 123. The air sucked from the suction port 112 is cooled by touching the metal plate. Thereby, the water vapor | steam contained in the air condenses on a metal plate. As a result, the amount of water vapor contained in the air that has passed through the dehumidifying unit 123 can be reduced.

As the dehumidifying unit 123, an internal air path for cooling air may be used. The air path is lengthened depending on the shape of the internal air path. Thereby, the contact area of the member and air which form an internal air path is enlarged, and air is cooled when passing an internal air path. Metal may be used as the material of the member forming the internal air path. In addition, a compressor or a heat pump may be used for the dehumidifying unit 123. The dehumidifying unit 123 may be provided with a pipe through which a refrigerant passes. When the air and the tube come into contact with each other, condensation occurs around the tube. A cooling element or the like (Peltier element or the like) may be used. Further, the dehumidifying unit 123 may be a hygroscopic substance. For example, as the dehumidifying part 123, a desiccant such as zeolite or silica gel can be used.
In the following description, it is assumed that the dehumidifying unit 123 is a compressor type dehumidifier.

  As shown in FIG. 3, the bathroom drying apparatus 100 may further include a discharge port 134. Thereby, by adjusting the position of the damper 136, the sucked air is discharged from the outlet 134 to the outside of the bathroom as indicated by an arrow A4.

  The control unit 120 is an electric circuit provided inside the housing 111 of the bathroom drying apparatus 100, for example. As shown in FIG. 4, the control unit 120 is connected to the fan 122, the heating unit 118, and the movable unit 124. The control unit 120 controls the operation (energization) of the fan 122, the operation (energization) of the heating unit 118, and the operation of the movable unit 124. When the dehumidifying unit 123 is a compressor or the like, the control unit 120 is connected to the dehumidifying unit 123 and controls the operation of the dehumidifying unit 123. As described above, the bathroom drying apparatus 100 sends “warm air” to the interior of the bathroom 10 to dry the bathroom 10, “heating operation” to warm the air in the bathroom 10, and ventilates the air in the bathroom “ Perform ventilation operation. Further, the bathroom drying apparatus 100 can execute a “blower operation” that blows out air along the ceiling 11 (or toward the ceiling 11).

  Moreover, the control part 120 is connected with the temperature detection means 125 and the remote control 20, for example by wire or radio | wireless. The temperature detection means 125 includes a thermometer (temperature sensor) that detects the temperature in the bathroom 10. The remote controller 20 is a remote controller for the user to instruct the bathroom drying apparatus 100 to drive. The control unit 120 controls the operation of the bathroom drying apparatus 100 based on signals from the temperature detection unit 125 and the remote controller 20.

FIG. 5A and FIG. 5B are schematic views illustrating the operation of the bathroom drying apparatus according to this embodiment.
FIG. 5A and FIG. 5B illustrate how the bathroom drying apparatus 100 blows air into the bathroom 10 from the air outlet 114.
In the operation of the bathroom drying apparatus 100, the fan 122 is controlled by the control unit 120, and air is blown out from the air outlet 114. At this time, the control unit 120 controls the direction (position) of the movable unit 124 relative to the bathroom 10 by rotating the movable unit 124. Thereby, the direction in which air is blown out from the blower outlet 114 is controlled.

In FIG. 5A, air is blown out from the outlet 114 to the ceiling 11 as indicated by an arrow A5 according to the position of the movable portion 124. For example, during the “air blowing operation”, air is blown out toward the ceiling 11 as shown in FIG.
In FIG.5 (b), according to the position of the movable part 124, as shown by arrow A6, air blows off toward the side wall 12 or the wash floor 13 from the blower outlet 114. As shown in FIG. For example, during the “drying operation”, air is blown out toward the washing floor 13 as shown in FIG.

  Thus, the bathroom drying apparatus 100 can change the direction in which air is blown out according to driving | operation. In addition, when the movable part 124 is not provided, the blower outlet 114 is arrange | positioned so that air blows off in the direction along the ceiling 11, for example.

Next, “blower operation” performed by the bathroom drying apparatus 100 will be described.
FIG. 6 is a schematic view illustrating the operation of the bathroom drying apparatus according to this embodiment.
The control unit 120 controls the fan 122, the heating unit 118, the dehumidifying unit 123, and the movable unit 124 based on a signal transmitted from the remote controller 20 or the temperature detection unit 125. Thereby, the control unit 120 controls the air blowing operation in which air is blown out from the blower outlet 114 along the ceiling 11.

  In this example, air in the bathroom 10 is sucked from the suction port 112 (first suction part 112a) in the air blowing operation. Then, the sucked air is blown into the bathroom 10 from the air outlet 114. That is, the air in the bathroom 10 circulates between the bathroom 10 and the bathroom drying device.

  This blowing operation is performed, for example, when the user is taking a bathing action (for example, using the shower 300) in the bathroom 10. When the user performs a bathing action, water vapor 310 is generated from hot water (or water) in the bathroom. In the air blowing operation, air with a small content of water vapor 310 generated in the bathroom is blown out from the outlet 114.

  For example, consider the absolute humidity of the air blown from the outlet 114 and the absolute humidity of the air in the bathroom 10 when the air blowing operation is performed. Here, absolute humidity is weight absolute humidity (kilogram / kilogram).

When the air blown from the blower outlet 114 is divided into the water vapor V1 and the dry air Dr1, the absolute humidity AH1 of the air blown from the blower outlet 114 is expressed by the following equation (1). The dry air Dr1 is the remainder obtained by removing the water vapor V1 from the air blown from the air outlet 114, and does not contain water vapor.
AH1 = mv1 / md1 (1)
Here, mv1 is the mass of the water vapor V1, and md1 is the mass of the dry air Dr1. Further, the mass mv1 of the water vapor V1 includes a mass ma1 of water vapor generated in the bathroom 10 and a mass mb1 of other water vapor. That is, AH1 = (ma1 + mb1) / md1 (2)
It is. Note that ma1 may be 0.

When the air in the bathroom 10 is divided into the dry air Dr2 and the water vapor V2, the absolute humidity AH2 of the air in the bathroom 10 is expressed by the following formula (3). The dry air Dr2 is the remainder obtained by removing the water vapor V2 from the air in the bathroom 10, and does not contain water vapor.
AH2 = mv2 / md2 (3)
Here, mv2 is the mass of the water vapor V2, and md2 is the mass of the dry air Dr2. Further, the mass mv2 of the water vapor V2 includes the mass ma2 of water vapor generated in the bathroom 10 and the mass mb2 of other water vapor. That is,
AH2 = (ma2 + mb2) / md2 (4)
It is.

At this time, during the air blowing operation, the component of water vapor generated in the bathroom 10 at the absolute humidity AH1 is smaller than the component of water vapor generated in the bathroom 10 at the absolute humidity AH2. That is,
ma1 / md1 <ma2 / md2 (5)
The relationship holds.

  In other words, the air blown from the blower outlet 114 during the air blowing operation includes the first mass (mv1 / md1) of water vapor with respect to the dry air of the unit mass. And the air in the bathroom 10 contains air vapor | steam of 2nd mass (mv2 / md2) with respect to dry air of unit mass during ventilation operation. The mass (ma1 / md1) of the water vapor generated in the bathroom 10 out of the first mass is smaller than the mass (ma2 / md2) of the water vapor generated in the bathroom 10 out of the second mass.

  When there is a humidity distribution in the bathroom 10, the average value of the humidity at a plurality of positions in the bathroom 10 can be considered as the humidity of the air in the bathroom 10. Alternatively, the humidity at the center position of the bathroom 10 may be considered as the humidity of the air in the bathroom 10.

  When the user is taking a bathing action, the air in the bathroom 10 contains a large amount of water vapor generated in the bathroom 10. Therefore, in this example, the air in the bathroom 10 is dehumidified by the dehumidifying unit 123. Then, the dehumidified air is blown out from the air outlet 114. Thereby, air with a small content of water vapor generated in the bathroom is blown out as in the above formula (5).

  As described above, air with a small content of water vapor generated in the bathroom 10 is blown out toward the ceiling 11. Thereby, generation | occurrence | production of the mold | fungi in the ceiling 11 can be suppressed. This will be described below.

  When the user takes a bath, water droplets adhere to the washing floor and side walls. Further, when water vapor is generated from the hot water used by the user during bathing and the water vapor reaches the ceiling, condensation occurs on the ceiling due to the difference between the temperature of the water vapor and the temperature of the ceiling. As a result, water droplets also adhere to the ceiling.

  The water droplets thus generated contain detergent, user's sebum and the like. For example, since water vapor generated in the bathroom 10 contains a lot of dirt such as sebum, water droplets generated on the ceiling due to condensation also contain sebum and the like. Such detergents and sebum are nutrients for mold. The bathroom is often an environment sufficient for mold to occur with respect to temperature and humidity. Therefore, the presence of nutrients makes it easy for mold to occur. For example, mold may grow at the location where the water droplets are attached.

  In particular, a lot of water (hot water) flows on the floor of the washroom during bathing. Therefore, in a conventional bathroom drying apparatus, drying is performed by sending warm air toward a wash floor or a side wall which is easy to get wet. Thereby, generation | occurrence | production of mold | fungi can be suppressed.

  Traditionally, it was thought that the wash floor was most likely to have dirty water droplets even in the bathroom. Therefore, in order to promote the flow of water and improve drainage on the washing floor, contrivances such as change of shape (gradient and unevenness) and material are made. However, according to the study by the inventors of the present application, it has been found that there may be more water droplets generated on the ceiling due to condensation than water droplets adhering to the washing floor. In addition, in the bathroom, the ceiling is not devised like the washroom floor, and furthermore, since it becomes water droplets from steam, it is difficult to drop water from the ceiling, it is a place where water droplets stay and the dirt is easy to accumulate was gotten. For this reason, when dew condensation occurs, it is considered that mold tends to occur on the ceiling. When mold occurs on the ceiling, this mold may release spores and spread the mold throughout the bathroom.

  As described above, since the conventional bathroom drying apparatus mainly dries easily contaminated portions such as the washing floor, it is difficult to effectively suppress the mold on the ceiling. On the other hand, in the bathroom drying apparatus 100 according to the present embodiment, air with a small content of water vapor generated in the bathroom 10 is blown out toward the ceiling 11. Thereby, as shown in FIG. 6, an air flow (air flow 320) is formed in the vicinity of the ceiling 11. For this reason, even if the water vapor 310 containing dirt rises toward the ceiling 11, it becomes difficult to reach the ceiling 11 by the airflow 320. Moreover, since the air blown toward the ceiling 11 is dehumidified air, the occurrence of condensation can be suppressed.

  Moreover, since the air blown toward the ceiling 11 is an air having a small content of water vapor generated in the bathroom 10, the amount of dirt such as sebum is also small. Therefore, the amount of dirt such as sebum contained in the airflow 320 is also small. For this reason, even if water droplets adhere to the ceiling 11 due to condensation, the sebum contained in the water droplets is small. Thereby, the stain | pollution | contamination of a ceiling can be suppressed. That is, the occurrence of mold caused by the dirt on the ceiling can be suppressed. Furthermore, mold spores can be prevented from scattering from the ceiling to the entire bathroom.

  Moreover, as already stated, in this example, the bathroom drying apparatus 100 circulates the air in the bathroom 10 in the blowing operation. By circulating the air in the bathroom 10, the difference between the temperature of the air blown from the outlet 114 and the temperature in the bathroom 10 can be reduced. Thereby, for example, since cold air outside the bathroom 10 is not taken into the bathroom 10 in winter or the like, the cold felt by the user can be suppressed and condensation on the ceiling of the bathroom can be suppressed.

  In the air blowing operation described above, the control unit 120 may control the operation of the heating unit 118 to heat the air sucked from the suction port 112. The ceiling 11 is warmed by the heated air being blown out from the air outlet 114. Thereby, even if it is a case where water vapor | steam reaches | attains a ceiling, it can suppress that dew condensation arises on a ceiling.

A specific example of the operation of the bathroom drying apparatus 100 will be further described.
FIG. 7 is a flowchart illustrating the operation of the bathroom drying apparatus according to this embodiment.
FIG. 8A to FIG. 8D are schematic views illustrating the operation of the bathroom drying apparatus according to this embodiment.

  As shown in FIG. 7, in step S <b> 101, the temperature detection unit 125 detects the temperature in the bathroom 10. The control unit 120 acquires information on the detected temperature. And the control part 120 determines the change per unit time of the detected temperature. FIG. 8A illustrates a change in bathroom temperature. For example, at time T1, a user starts a bathing action such as using a shower. At this time, the temperature in the bathroom 10 rises as shown in FIG. 8A due to the heat of hot water supplied from the shower. For this reason, the start of the user's bathing action can be detected by detecting the temperature in the bathroom 10. If the detected increase in temperature per unit time is equal to or greater than the predetermined value n1, step S102 is executed. The predetermined value n1 can be set as appropriate in order to detect the start of the user's bathing action.

  In step S102, the above-described air blowing operation (ceiling air blowing operation) is started. That is, the control unit 120 controls the heating unit 118, the fan 122, the dehumidifying unit 123, and the movable unit 124 (electric louver). FIG. 8B illustrates the operation of the heating unit 118 and the operation of the fan 122. For example, the air blowing operation is started between time T1 and time T2. That is, as shown in FIG. 8B, energization of the heating unit 118 and energization of the fan 122 are started. FIG. 8C illustrates the operation of the movable unit 124. The position of the movable unit 124 is controlled by the control unit 120 between the time T1 and the time T2. Thereby, the movable part 124 moves to a position where air is blown out toward the ceiling 11.

  Thereafter, as shown in FIG. 7, the air blowing operation is continued. For example, while the user is taking a bath, water vapor is continuously generated in the bathroom 10. For this reason, it is desirable to continue the air blowing operation while the user bathes. For example, while the user is taking a bath until time T3, as shown in FIG. 8A, the temperature of the bathroom is maintained high until time T3.

  While the air blowing operation is continued, the temperature detection unit 125 detects the temperature in the bathroom 10, and the control unit 120 acquires information on the detected temperature. In step S103, the control unit 120 determines the detected temperature change. As shown to Fig.8 (a), when a user's bathing action is complete | finished, the temperature in a bathroom will fall. For this reason, the end of the user's bathing action can be detected by detecting the temperature in the bathroom 10. When the detected temperature decrease is equal to or greater than the predetermined value n2, the control unit 120 ends the air blowing operation. When the detected decrease in temperature is less than the predetermined value n2, the control unit 120 continues the air blowing operation. The predetermined value n2 can be set as appropriate. For example, the air blowing operation ends when the temperature is decreased by a predetermined value n2 or more from the maximum temperature detected after the air blowing operation is started. For example, the air blowing operation ends at time T4. That is, as shown in FIG. 8B, at time T4, the energization of the heating unit 118 and the energization of the fan 122 are terminated. Moreover, as shown in FIG.8 (c), you may move the position of the movable part 124 after completion | finish of ventilation operation.

  During bathing by the user, water vapor is generated in the bathroom and condensation tends to occur. Therefore, the air blowing operation is performed in accordance with the user's bathing. Thereby, generation | occurrence | production of the stain | pollution | contamination of a ceiling and dew condensation can be suppressed. As described above, it is possible to detect the start of the user's bathing action by detecting the temperature in the bathroom 10 by the temperature detecting means 125. Since the air blowing operation is started in response to the temperature rise, the user himself / herself does not need to start the air blowing operation in the bathroom drying apparatus 100 every time the user takes a bath. Thereby, the usability of the bathroom drying apparatus 100 can be improved.

  In addition, after the bathing action is completed, water vapor generated in the bathroom by the bathing action may remain in the bathroom 10. The remaining water vapor may cause condensation on the ceiling 11. On the other hand, the bathroom drying apparatus 100 according to the embodiment continues the air blowing operation after the start of the air blowing operation until the temperature in the bathroom decreases by a predetermined value or more. That is, after the bathing action is completed, the air blowing operation is continued until the temperature drops by a predetermined value or more. Thereby, it can suppress that the water vapor | steam which remained in the bathroom 10 reaches | attains a ceiling after a bathing act. Therefore, the stain | pollution | contamination of the ceiling by dew condensation can be suppressed.

FIG. 8D is a table illustrating the amount of water (arbitrary unit) attached to the ceiling.
As shown in FIG. 8D, when the air blowing operation described with reference to FIGS. 8A to 8C is not performed, the amount of moisture attached to the ceiling by the user's bathing is 50. In contrast, when the air blowing operation described with reference to FIGS. 8A to 8C is performed, the amount of moisture attached to the ceiling by the user's bathing is 25. That is, it can be seen that the generation of condensation on the ceiling 11 is suppressed by blowing the air that has passed through the dehumidifying unit 123 and dried toward the ceiling 11.

FIG. 9 is a schematic view illustrating the main configuration of another bathroom drying apparatus according to this embodiment.
The bathroom drying apparatus 101 illustrated in FIG. 9 is different from the bathroom drying apparatus 100 described with reference to FIG. 2 in that the bathroom drying apparatus 101 includes the second suction portion 112b.

  That is, the bathroom drying apparatus 101 includes a heating unit 118, a control unit 120, a fan 122, and a dehumidifying unit 123, similarly to the bathroom drying apparatus 100. Furthermore, the bathroom drying apparatus 101 has an air passage 116a. The air passage 116a has a suction port 112 (a first suction portion 112a and a second suction portion 112b) and a blowout port 114. In the bathroom drying apparatus 101 as well, like the bathroom drying apparatus 100, the movable part 124 (electric louver) and the heating part 118 are not necessarily provided.

  The second suction part 112b communicates with the outside of the bathroom 10 (for example, a dressing room provided adjacent to the bathroom 10). As a result, the air passage 116a communicates with the outside via the second suction portion 112b. In addition, in FIG. 3, the 2nd suction part 112b is illustrated collectively.

  As shown by an arrow A5 in FIG. 9 (and FIG. 3), the suction port 112 (second suction part 112b) sucks air outside the bathroom 10 according to the operation of the fan 122. The sucked air is blown out into the bathroom 10 from the air outlet 114, for example.

  For example, the bathroom drying apparatus 101 may further include a damper 126. The damper 126 is located between the fan 122 and the first suction part 112a on the air passage 116a. The damper 126 is positioned between the fan 122 and the second suction part 112b on the air passage 116a. The damper 126 has, for example, a valve that adjusts the flow rate of air.

  Depending on the position (operation) of the damper 126, the flow rate of air sucked from the first suction portion 112a and the flow rate of air sucked from the second suction portion 112b can be adjusted. For example, the damper 126 can switch between a state in which air is sucked from the first suction part 112a and a state in which air is sucked from the second suction part 112b. Further, air may be sucked from both the first suction part 112a and the second suction part 112b. The operation of the damper 126 is controlled by the control unit 120, for example.

  The bathroom drying apparatus 101 performs a blowing operation of blowing air toward the ceiling 11 as in the description related to FIGS. 6 and 7. In this air blowing operation, the suction port 112 (second suction part 112b) can suck air from outside the bathroom. And the blower outlet 114 blows off the air sucked from the outside of the bathroom toward the ceiling 11. Air sucked from outside the bathroom is substantially free of water vapor generated in the bathroom. For this reason, the relationship of the above-mentioned formula (5) is established even during the air blowing operation of the bathroom drying apparatus 101.

  In the bathroom drying apparatus 101 as well, the amount of water vapor generated in the bathroom reaching the ceiling can be reduced by the air blowing operation, as in the description related to FIG. Furthermore, by taking in air outside the bathroom, the amount of water vapor generated in the bathroom in the air blown out along the ceiling of the bathroom can be further reduced. Thereby, even when condensation occurs on the ceiling, dirt such as sebum on the ceiling can be suppressed. Therefore, the occurrence of mold can be further suppressed.

  In addition, regarding the air sucked from outside the bathroom, the relationship of the above formula (5) is established even when the air does not pass through the dehumidifying unit 123. Therefore, when the second suction part 112b is provided, the dehumidifying part 123 is not necessarily provided.

  As described above, according to the present embodiment, air with a small content of water vapor generated in the bathroom is blown out toward the ceiling. Thereby, generation | occurrence | production of the mold | fungi in a ceiling can be suppressed.
