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 is a bathroom drying apparatus which dries a bathroom which has a washroom floor, a side wall, and a ceiling, Comprising: The suction port which sucks in the air in the said bathroom, and the air suck | inhaled by the said suction mouth into the said bathroom An air passage having a blow-out opening, a heating unit that heats air sucked by the suction port, a bath detection unit that detects that the user bathes, and the bath detection unit that allows the user to take a bath And a control unit that performs a first control for controlling the heating unit so that the ceiling is heated by the air blown out from the outlet toward the ceiling. This is a featured bathroom drying device. The blower outlet is air blown from the blower outlet into a first range that blows air directly toward the ceiling and a second range that blows air directly toward the side wall or the wash floor. The movable part which changes the direction of the is included. The bathing detection means detects or receives information related to a preliminary operation performed before the user bathes, and transmits a signal related to the information to the control unit. The controller warms the ceiling before the user bathes by positioning the movable part in the first range based on the signal and performing the first control.

According to this bathroom drying apparatus, the temperature difference between the steam generated in the bathroom and the ceiling during bathing by the user can be reduced by heating the ceiling of the bathroom. Thereby, even if the steam reaches the ceiling, it is possible to suppress the occurrence of condensation. By suppressing the condensation on the ceiling, it is possible to suppress the occurrence of mold on the ceiling. 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. Moreover, since the first control to warm the ceiling is started based on the preliminary operation such as the start of hot water filling in the bathtub or the entrance to the dressing room, the time until the user starts bathing is used effectively. And warm the ceiling. Therefore, when the user starts bathing, the ceiling can be kept warm, and the occurrence of condensation on the ceiling can be suppressed. Thereby, it can suppress efficiently that mold | fungi generate | occur | produce on a ceiling.

According to a second invention, in the first invention, the control unit further performs a second control for controlling the heating unit so that the interior of the bathroom is warmed by the air blown from the air outlet. The bathroom drying device is characterized in that the amount of air blown from the outlet in the first control is smaller than the amount of air blown from the outlet in the second control.

  According to this bathroom drying apparatus, the air volume in the first control for heating the ceiling is smaller than the air volume in the second control for heating the interior of the bathroom. Thereby, in 1st control, warm air can be made to stay in ceiling vicinity, and a ceiling can be warmed efficiently.

The third invention is the first or second aspect of the invention, the front Symbol controller, the second control for controlling the heating unit as in the bathroom is warmed by the air blown from the air outlet second 3rd control which implements 1 control alternately is performed, the said movable part is controlled so that air blows off toward the 1st area | region of the said ceiling from the said blower outlet in said 1st control, and said 2nd control In the third control, the movable portion is controlled so that air is blown out from the outlet to the second area of the washing floor and the side wall, and in the third control, the first area with respect to the area of the first area is controlled. The bathroom drying apparatus is characterized in that the ratio of the amount of heat of air blown toward the second area is higher than the ratio of the amount of heat of air blown toward the second area with respect to the area of the second area.

  According to this bathroom drying apparatus, the ceiling is warmed before the user takes a bath, and the interior of the bathroom is further warmed. At this time, the amount of heat of air blown toward the ceiling is relatively large. Thereby, a ceiling can be warmed in a short time compared with the case where air is blown out in the same way in all directions. For example, when the ceiling warming is started in response to the filling of the hot water in the bathtub, even if the steam generated during the filling of the hot water reaches the ceiling, the ceiling is warmed in a short time, so that the occurrence of condensation is suppressed. Cheap.

According to a fourth aspect of the present invention based on the third aspect , in the third control, the control unit performs the first control according to a length of time for performing the first control and a length of time for performing the second control. It is a bathroom drying apparatus characterized by controlling the amount of heat of air blown toward the region and the amount of heat of air blown toward the second region.

  According to this bathroom drying apparatus, the amount of heat of the blown air can be adjusted according to the length of time, and the control is simple. For this reason, switching between the first control and the second control can be performed smoothly.

  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 passage 116, a heating unit 118, a control unit 120, and a fan 122. The air passage 116 has a suction port 112 and an air outlet 114. Furthermore, the bathroom drying apparatus 100 includes a bathing detection unit 110 (see FIGS. 1 and 4).

  In this example, the bathroom drying apparatus 100 is 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 suction inlet 112 and the blower outlet 114 each lead to the bathroom 10. As a result, the air passage 116 communicates with the interior of the bathroom 10 through the suction port 112 and the air 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 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.

  In addition, as illustrated in FIG. 3, the bathroom drying apparatus 100 may further include a suction port 132 and a discharge port 134. Thereby, outside air (for example, the air of the dressing room provided adjacent to the bathroom 10) is sucked from the suction port 132 as indicated by an arrow A3. Further, by adjusting the position of the damper 136, the sucked air is discharged from the discharge port 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. The control unit 120 is connected to the bathing detection means 110, the fan 122, and the heating unit 118. The control unit 120 controls the operation (energization) of the fan 122 and the operation (energization) of the heating unit 118. As a result, the bathroom drying apparatus 100 performs a “drying operation” in which warm air is sent into the bathroom 10 to dry the bathroom 10. Further, the bathroom drying apparatus 100 performs “ventilation operation” for ventilating the air inside the bathroom 10, “heating operation” for heating the air inside the bathroom 10, and “ceiling warming operation” for heating the ceiling 11. can do.

  The bathing detection means 110 detects that the user of the bathroom 10 bathes. Here, “taking a bath” includes taking a bath by a user after a certain time. For example, the bathing detection unit 110 detects information related to a preliminary operation performed before the user bathes. The bathing detection unit 110 transmits a detection result (a signal corresponding to the detected information) to the control unit 120.

  When the bathing detection unit 110 detects that the user bathes, the control unit 120 performs the first control (ceiling warming mode) based on the signal transmitted from the bathing detection unit 110. In the first control, the control unit 120 controls the heating unit 118 and the fan 122 so that the ceiling 11 is warmed by the air blown from the outlet 114.

  Here, as an example, the user's preliminary operation before bathing is that the user gives an instruction to start filling the bathtub 14 to the water heater prior to bathing. In the example shown in FIG. 1, the bathing detection means 110 is a water level sensor installed in the bathtub 14. The water level sensor can detect that hot water filling is performed. As a result, it can be seen that the user has performed a preliminary operation instructing the start of hot water filling. That is, it is detected that the user takes a bath after filling with hot water.

  For the water level sensor, any method such as a capacitance type, a pressure type, a float type or an ultrasonic type can be used. The capacitance type is a method for detecting the dielectric constant of water (hot water). The pressure type is a method for detecting the pressure of water. The float type is a method for detecting a change in the position of a float (floating) caused by water. The ultrasonic method is a method of detecting reflection of ultrasonic waves on the water surface.

  Moreover, the bathing detection means 110 may detect that a button or the like provided on the remote controller 21 or the like of the water heater is instructed to start hot water filling as a preliminary operation. In this case, for example, the bathing detection unit 110 includes a signal receiving unit provided inside the bathroom drying apparatus 100 or the like. For example, when a button for instructing the start of hot water filling is pressed, a signal related to hot water filling is transmitted from the remote control 21 to the bathing detection means 110. The bathing detection means 110 can detect that the user bathes by receiving this signal. Note that the method of transmitting and receiving the signal may be any method such as wired or wireless.

  The preliminary operation may be that the user has entered the bathroom 10 or that the user has entered a dressing room provided adjacent to the bathroom 10. In this case, the bathing detection means 110 is a sensor that is provided in the bathroom 10 or the dressing room and detects a user's entrance. For example, an infrared light projecting / receiving type distance sensor can be used as the sensor for detecting entry. By detecting the human body, the user's entry can be detected. Thereby, for example, it can be detected that the user takes a bath after entering the dressing room.

  Moreover, the bathing detection means 110 may detect a user's operation on the bathroom drying apparatus 100 itself as a preliminary operation. For example, the user uses a function (for example, “ceiling warming”) of the bathroom drying apparatus 100 by pressing a button on the remote controller 20 for controlling the operation (operation) of the bathroom drying apparatus 100. In this case, bathing detection means 110 includes a button on remote controller 20. Thereby, you may detect that a user bathes after that.

  In addition, the detection of the user bathing may be performed by detecting the on / off of the lighting in the dressing room and receiving the signal. In addition, the detection of the user bathing may be received by a sensor such as a microphone that the water heater informs the user of the start of hot water filling or the end of hot water filling.

  Note that the bathing detection means 110 is not limited to the above operation, and may detect that the user is bathing. Moreover, bathing includes not only using the hot water stretched in the bathtub by the user but also using hot water (water) supplied from a shower or water provided in the bathroom 10.

  When the user takes a bath, water droplets adhere to the washing floor and side walls. Further, when steam is generated from the hot water used by the user during bathing and the steam reaches the ceiling 11 due to the difference between the temperature of the steam and the temperature of the ceiling, condensation occurs on 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, when the bathing detection unit 110 detects the user's bathing, the control unit 120 performs the first control to warm the ceiling. By heating the ceiling, the difference between the temperature of the steam generated during bathing by the user and the temperature of the ceiling can be reduced. Thereby, even if vapor | steam reaches | attains a ceiling, generation | occurrence | production of the dew condensation of a ceiling can be suppressed. Since it can suppress that a water droplet adheres to a ceiling, generation | occurrence | production of mold | fungi can be prevented.

  Moreover, 1st control is implemented based on the information regarding the preliminary | backup operation | movement before a user's bathing. For this reason, when the user starts bathing, the ceiling is in a warmed state. Thereby, generation | occurrence | production of the dew condensation of a ceiling can further be suppressed. Therefore, it is possible to efficiently suppress the occurrence of mold on the ceiling.

FIG. 5A and FIG. 5B are schematic views illustrating the operation of the bathroom drying apparatus according to this embodiment.
FIG. 5A illustrates a state in which the bathroom drying apparatus 100 performs “ceiling warming operation”. That is, FIG. 5A illustrates a state when the control unit 120 is performing the first control.
FIG. 5B illustrates a state in which the bathroom drying apparatus 100 is performing “heating operation”. At this time, the control unit 120 performs the second control (heating mode). In the second control, the control unit 120 controls the heating unit 118 and the fan 122 so that the interior of the bathroom 10 is warmed by the air blown from the air outlet 114. In heating operation, the cold in the bathroom is alleviated by sending warm air into the bathroom. For example, the interior of the bathroom is warmed by the heating operation before the user bathes.

  As indicated by an arrow A6 in FIG. 5B, when the second control is performed, a relatively strong hot air is sent into the bathroom 10. Thereby, a warm air flows, for example along the side wall 12 or the washing-room floor 13, and heats the whole bathroom efficiently.

  On the other hand, as shown by an arrow A5 in FIG. 5A, when the first control (ceiling warming mode) is performed, the air outlet 114 has a relatively weak momentum to allow hot air to enter the bathroom 10. Blow out. Due to the weak momentum, hot air tends to stay above the bathroom 10. For example, as shown in FIG. 5A, a hot air layer 30 is formed in the vicinity of the ceiling 11. Thereby, the ceiling 11 can be warmed efficiently.

  That is, according to the present embodiment, the amount of air blown from the outlet 114 in the first control (the amount of air per unit time) is smaller than the amount of air blown from the outlet 114 in the second control. Thereby, a ceiling can be warmed efficiently.

  In the example shown in FIGS. 5A and 5B, the first control and the second control are switched by changing the air volume. For example, the output of the fan 122 in the second control is higher than the output of the fan 122 in the first control.

  However, in the embodiment, the first control and the second control may be switched by changing the temperature of the hot air blown from the blower outlet 114. For example, the output of the heating unit 118 in the first control is set higher than the output of the heating unit 118 in the second control. Thereby, in the first control, relatively hot air is blown out. Since hot air tends to stay upward, for example, a hot air layer 30 is likely to be formed. Thereby, the ceiling 11 can be warmed efficiently.

  Note that both the air volume and the temperature may be changed as switching between the first control and the second control. Further, as will be described below, the first control and the second control may be switched by changing the direction in which the warm air is blown out. In this case, the air volume and temperature need not be changed. The first control and the second control may be switched by changing the combination of the direction in which the hot air is blown, the air volume, and the temperature as appropriate.

FIG. 6 is a schematic diagram illustrating a main configuration of another bathroom drying apparatus according to the present embodiment. In FIG. 6, the air path system and the electrical system are shown together.
FIG. 7 is a block diagram illustrating another bathroom drying apparatus according to this embodiment.
FIG. 8 is a schematic view illustrating the operation of another bathroom drying apparatus according to this embodiment.
The bathroom drying apparatus 100a illustrated in FIGS. 6 to 8 is similar to the bathroom drying apparatus 100 described with reference to FIGS. 1 to 4, and includes a suction port 112, an air passage 116, a heating unit 118, a control unit 120, a fan 122, and a bath. It has a detection means 110.
Furthermore, the bathroom drying apparatus 100a has an outlet 114a including a movable portion 124. Except the movable part 124, the blower outlet 114a is the same as the description regarding FIGS.

  The movable part 124 changes the direction of the air blown from the blower outlet. The movable part 124 is an electric louver, for example. By changing the angle of the louver relative to the bathroom 10, the direction in which air is blown out can be changed. For example, as shown in FIG. 7, the movable unit 124 is electrically connected to the control unit 120, and the control unit 120 controls the operation of the movable unit 124.

  For example, the movable part 124 can move (rotate) in the range Sa as shown in FIG. The range Sa includes a first range S1 and a second range S2. In the first range S1, the movable portion 124 (louver) is in a state facing the direction of the ceiling 11, and in the second range S2, the movable portion 124 is in a state facing in the direction of the side wall 12 or the washing place floor 13.

That is, when the movable part 124 is in the first range S1, the air outlet 114a blows out air toward the first region R1 (at least a part of the ceiling 11).
When the movable part 124 is in the second range S2, the air outlet 114a blows out air toward the second region R2. Here, the second region R2 is at least a part of the side wall 12 (region R21) and at least a part of the washing floor 13 (region R22).

  In the first control for heating the ceiling, the control unit 120 controls the fan 122, the heating unit 118, and the movable unit 124 so that the position of the movable unit 124 is within the first range S1. In addition, in the second control for warming the bathroom, the control unit 120 controls the fan 122, the heating unit 118, and the movable unit 124 so that the position of the movable unit 124 is within the second range S2. As described above, by controlling the direction of the hot air using the movable portion 124, it is possible to perform a more efficient operation.

Next, a specific example of the operation of the bathroom drying apparatus 100a will be described.
FIG. 9 is a flowchart illustrating the operation of another bathroom drying apparatus according to this embodiment. FIG. 10A to FIG. 10B and FIG. 11A to FIG. 11C are schematic views illustrating the operation of another bathroom drying apparatus according to this embodiment.
In this example, the control unit 120 performs a third control that alternately performs a first control that warms the ceiling and a second control that warms the interior of the bathroom. Thereby, when a user takes a bath, the ceiling can be warmed and the interior of the bathroom can be warmed.

  In step S <b> 101 shown in FIG. 9, the bathroom drying apparatus 100 a detects the user's bathing by the bathing detection unit 110. This detection is similar to the bathroom drying apparatus 100 described with reference to FIGS. If it is detected that the user takes a bath, the process proceeds to step S102.

  In step S102, the control unit 120 performs the first control. At this time, warm air is blown out from the blower outlet 114a toward the ceiling 11 as indicated by an arrow A7 shown in FIG.

  At this time, the movable portion 124 moves within the first range S1. For example, the movable part 124 moves from the position P1 (the end of the first range S1) to the position P2 (the other end of the first range S1), and returns to the position P1 again. Note that the start position of the movement of the movable portion 124 is not limited to the position P1, and may be any position, for example, the position P2.

  The moving speed (absolute value of the rotational speed) of the movable part 124 in the first range S1 is, for example, V1 as shown in FIG. In addition, the vertical axis | shaft of Fig.11 (a) represents the moving speed of the movable part 124, and a horizontal axis represents time.

  As shown in step S103, the first control for warming the ceiling is continued until a predetermined time Tm1 elapses. The predetermined time Tm1 is, for example, the time until the position P1 is reached when the movable part 124 moves within the first range S1.

  When the predetermined time Tm1 has elapsed, in step S104, the control unit 120 performs the second control. At this time, as shown by an arrow A8 shown in FIG. 10B, warm air is blown out from the outlet 114a toward the side wall 12 or the washing floor 13.

  At this time, the movable portion 124 moves within the second range S2. For example, the movable part 124 moves from the position P1 (the end of the second range S2) to the position P3 (the other end of the second range S2), and returns to the position P1 again. The moving speed of the movable part 124 within the second range S2 is, for example, V2 as shown in FIG. V2 is larger than V1.

  As shown in step S105, the second control for heating the interior of the bathroom 10 is continued until a predetermined time Tm2 elapses. The predetermined time Tm2 is, for example, a time until the movable part 124 moves in the second range S2 and reaches the position P1 again.

The control unit 120 repeats steps S102 to S105 as described above. In this way, the first control and the second control are repeatedly performed alternately.
The third control by the control unit 120 ends when, for example, the user finishes bathing and instructs the bathroom drying apparatus from the remote controller 20 to “ventilation operation”. Alternatively, the user may instruct the bathroom drying apparatus to end the operation. The operation may be terminated when a predetermined time elapses using a timer or the like. In addition, the end of bathing may be detected using a sensor similar to the bathing detection means, and the operation may be automatically terminated.

  As described with reference to FIG. 11A, in this specific example, the moving speed of the movable portion 124 is adjusted. The predetermined time in steps S102 and S105 is determined by the moving speed of the movable portion 124. For this reason, the length of the execution time of the first control and the length of the execution time of the second control are adjusted by adjusting the moving speed.

  The amount of heat of the air blown toward the first region R1 is controlled by the length of time for which the first control is performed, that is, the length of time that the warm air is blown toward the first region R1. In addition, the amount of heat of the air blown toward the second region R2 is controlled by the length of time for performing the second control, that is, the length of time for which the warm air is blown toward the second region R2. .

In FIG. 11B, the vertical axis represents the amount of heat supplied to each region, and the horizontal axis represents time.
The ratio of the amount of heat (C1) of the air blown toward the first region R1 in steps S102 and S103 to the area (Ar1) of the first region R1 is C1 / Ar1.
The ratio of the amount of heat (C2) of the air blown toward the second region R2 in steps S104 and S105 to the area (Ar2) of the second region R2 is C2 / Ar2.
As shown in FIG. 11B, C1 / Ar1 is higher than C2 / Ar2.

  Thus, in the third control, the amount of heat of the air blown toward the first region R1 is controlled to be larger than the amount of heat of the air blown toward the second region R2. Thereby, a ceiling can be warmed in a short time compared with the case where air is blown out in the same way in all directions. For example, when the third control is started in response to hot water filling, even if steam generated during hot water filling reaches the ceiling, the ceiling is warmed in a short time, so that it is easy to suppress the occurrence of condensation.

The amount of heat (C1) may be considered as the amount of heat supplied to the first region R1 in the third control (temperature change of the first region R1), and the amount of heat (C2) is the second region R2 in the third control. It may be considered that the amount of heat supplied to (temperature change in the second region R2).
Further, in the examples of FIGS. 11A and 11B, the amount of heat (C1) includes the output (W) of the heating unit 118 in the first control, the time for performing the first control (predetermined time Tm1), The amount of heat (C2) corresponds to the product of the output (W) of the heating unit 118 in the second control and the time for performing the second control (predetermined time Tm2).

FIG. 11C is a table illustrating the amount of water (arbitrary unit) adhering to the ceiling.
When the ceiling temperature is room temperature, the amount of water adhering to the ceiling by the user's bathing is 30. On the other hand, when the ceiling temperature is set to 35 ° C., 40 ° C., and 45 ° C. by performing ceiling warming (first control) in advance of bathing, , 15, 5, 0. That is, it can be seen that condensation is suppressed by supplying a large amount of heat to the ceiling and raising the temperature of the ceiling.

  In the operation described above, switching between the first control and the second control is performed by the direction of the movable part 124 and the moving speed of the movable part 124. In this specific example, as described above, the time for each control is adjusted according to the moving speed of the movable portion 124, whereby the amount of heat of the blown air can be adjusted. At this time, the temperature of the warm air (the output of the heating unit 118) and the air volume (the output of the fan 122) are constant, for example. For this reason, control is easy. Therefore, it is possible to smoothly switch between the first control and the second control.

  However, in the embodiment, as shown in FIG. 12A, switching between the first control and the second control depends on the direction of the movable part 124 and the temperature of the hot air (output of the heating part). It may be done. For example, the temperature T1 of the warm air in the first control is set higher than the temperature T2 of the warm air in the second control. Thereby, it is possible to control the amount of heat as in FIG.

  Further, as shown in FIG. 12B, the switching between the first control and the second control may be performed by the direction of the movable portion 124 and the air volume (the output of the fan 122). For example, the air volume Av1 in the first control is made smaller than the air volume Av2 in the second control. Thereby, hot air tends to stay in the vicinity of the ceiling 11, and the ceiling 11 can be efficiently heated.

  In the switching between the first control and the second control, the direction of the movable part 124, the moving speed of the movable part 124, the air volume, and the temperature may be changed in appropriate combination.

  As described above, according to the present embodiment, the ceiling is warmed before the user bathes, thereby suppressing condensation on the ceiling during bathing. Thereby, it can suppress that mold | fungi generate | occur | produce on a ceiling.
