The operation unit 5 is provided on the upper surface of the housing 1. The operation unit 5 has a display unit 5a. For example, the water storage tank 6 is detachably provided in the housing 1.

  The operation unit 5 is, for example, a push button or a touch panel. The display unit 5a is, for example, a liquid crystal display or a touch panel. The touch panel can serve as both the operation unit 5 and the display unit 5a.

  FIG. 2 is a schematic configuration diagram showing the inside of the dehumidifier in the first embodiment.

  As shown in FIG. 2, the dehumidifier includes a blower fan 7, a temperature sensor 8, a humidity sensor 9, a dehumidifying unit 10, a water level sensor 11, and a control unit 12. Inside the housing 1, an air passage extending from the suction port 2 to the air outlet 3 is formed. The blower fan 7, the temperature sensor 8, the humidity sensor 9, and the dehumidifying unit 10 are provided in the air path. The temperature sensor 8 and the humidity sensor 9 are disposed closer to the suction port 2 than the dehumidifying unit 10. The blower fan 7 is disposed closer to the air outlet 3 than the dehumidifying unit 10. The control unit 12 is electrically connected to the operation unit 5, the display unit 5 a, the blower fan 7, the temperature sensor 8, the humidity sensor 9, the dehumidifying unit 10, and the water level sensor 11.

  The operation unit 5 receives an operation by a user of the dehumidifier. The operation received by the operation unit 5 is, for example, an operation for turning on or off the power supply of the dehumidifier. The operation received by the operation unit 5 is, for example, an operation for determining the operation mode of the dehumidifier.

  The display unit 5a displays information indicating the usage state of the dehumidifier with, for example, characters, symbols, images, and the like. The display unit 5a may display information by, for example, lighting and blinking of a lamp.

  The blower fan 7 generates an airflow from the suction port 2 toward the blowout port 3 in the air path. That is, the blower fan 7 functions as a blower that blows out the air sucked into the housing 1 from the suction port 2 through the blowout port 3.

  The temperature sensor 8 detects the temperature of air sucked into the housing 1 from the suction port 2. That is, the temperature sensor 8 functions as a temperature detection unit that detects the temperature of the indoor air A. The humidity sensor 9 detects the humidity of the air sucked into the housing 1 from the suction port 2. That is, the humidity sensor 9 functions as a humidity detection unit that detects the humidity of the room air A. Signals indicating detection results by the temperature sensor 8 and the humidity sensor 9 are transmitted to the control unit 12.

  The dehumidifying unit 10 removes moisture from the passing air. That is, the dehumidifying unit 10 removes moisture contained in the room air A and generates dry air B. The water removed from the room air A by the dehumidifying unit 10 is stored in the water storage tank 6 as condensed water. The water level sensor 11 functions as a water amount detection unit that detects the amount of water stored in the water storage tank 6. A signal indicating the detection result by the water level sensor 11 is transmitted to the control unit 12.

  The dehumidification part 10 should just be what can remove and condense the water | moisture content in air. For example, the dehumidifying unit 10 may use a method of condensing moisture in the air in an evaporator of a heat pump circuit. The dehumidifying unit 10 may use, for example, a desiccant method in which moisture in the air removed by the adsorbent is condensed by a heat exchanger.

  The control unit 12 can control the operations of the display unit 5 a, the blower fan 7, and the dehumidifying unit 10 based on the operation received by the operation unit 5. The control unit 12 can control the operations of the display unit 5 a, the blower fan 7, and the dehumidifying unit 10 based on at least one of detection results from the temperature sensor 8, the humidity sensor 9, and the water level sensor 11.

  For example, when the control unit 12 detects that the operation mode of the dehumidifier is determined as the clothing drying mode by the operation received by the operation unit 5, the control unit 12 drives the blower fan 7 and the dehumidifying unit 10. Thereby, the indoor air A is taken into the inside of the housing 1 from the suction port 2 as indicated by arrows in FIGS. The room air A is dehumidified by the dehumidifying unit 10 to become dry air B. The dry air B is blown out into the room from the air outlet 3 as shown by arrows in FIGS. The dry air B passes through the louver 4 when blown out from the air outlet 3.

  The control unit 12 controls the dehumidifying unit 10 according to the amount of water detected by the water level sensor 11. For example, when the control unit 12 detects that the amount of water in the water storage tank 6 is equal to or greater than a preset value based on a signal from the water level sensor 11, the control unit 12 stops the operation of the dehumidifying unit 10.

  FIG. 3 is an enlarged schematic perspective view showing the louver in the first embodiment.

  As shown in FIG. 3, the dehumidifier includes a wind direction plate 13, a wind direction plate driving motor 14, and a louver driving motor 15. A plurality of wind direction plates 13 are provided inside the louver 4 along the vertical direction. The wind direction plate 13 is provided so as to be able to rotate left and right within a certain angle range. The individual wind direction plates 13 can also form different angles with respect to the louver 4. The louver 4 is provided so as to be rotatable up and down within a certain angle range. The wind direction plate driving motor 14 and the louver driving motor 15 are electrically connected to the control unit 12.

  As shown in FIG. 3, the dehumidifier includes an infrared sensor 16 and an irradiation unit 17. The infrared sensor 16 and the irradiation part 17 are attached to the wind direction board 13 arrange | positioned at the center of the louver 4, for example. The infrared sensor 16 and the irradiation unit 17 are electrically connected to the control unit 12.

  The wind direction plate driving motor 14 rotates the wind direction plate 13 left and right within a certain angle range. That is, the wind direction plate driving motor 14 changes the direction of the wind direction plate 13 in the horizontal direction. The individual wind direction plates 13 can also face in different directions. The louver driving motor 15 rotates the louver 4 up and down within a certain angle range. That is, the louver drive motor 15 changes the direction of the louver 4 in the vertical direction. The direction of the dry air B blown out from the blower outlet 3 changes according to the direction of the wind direction plate 13 and the louver 4. That is, the louver 4, the wind direction plate 13, the wind direction plate driving motor 14, and the louver driving motor 15 function as a wind direction changing unit that changes the direction of the air blown out from the air outlet 3.

  The infrared sensor 16 detects the surface temperature of the object. When the infrared sensor 16 is attached to the wind direction plate 13, the infrared sensor 16 detects the surface temperature of the object in the same direction as the direction of the wind direction plate 13 and the louver 4. In this case, the range in which the surface temperature can be detected by the infrared sensor 16 is equivalent to the range in which the dry air B blown from the blowout port 3 can be blown. The infrared sensor 16 functions as a dryness detection unit that detects the dryness of an object to be dried such as laundry that has been dried indoors. The dryness is, for example, the surface temperature itself of the material to be dried or a value calculated from the surface temperature. A signal indicating the detection result by the infrared sensor 16 is transmitted to the control unit 12.

  The dryness detection by the infrared sensor 16 is performed periodically, for example. The detection of the dryness by the infrared sensor 16 may be performed, for example, when necessary according to the control of each unit by the control unit 12.

  The irradiation unit 17 emits light. The irradiation unit 17 uses, for example, an LED light source or a laser light source. When the irradiation unit 17 is attached to the wind direction plate 13, the irradiation unit 17 emits light in the same direction as the direction of the wind direction plate 13 and the louver 4. In this case, the range in which the light from the irradiation unit 17 can be irradiated is equivalent to the range in which the dry air B blown from the blowout port 3 can be blown.

  The control unit 12 can control the operations of the wind direction plate driving motor 14, the louver driving motor 15, and the irradiation unit 17 based on the operation received by the operation unit 5. The control unit 12 can control operations of the display unit 5 a, the blower fan 7, the dehumidifying unit 10, the wind direction plate driving motor 14, the louver driving motor 15, and the irradiation unit 17 based on the detection result by the infrared sensor 16. Is possible.

  Control part 12 sets up a plurality of blowable areas as what divided the whole range which can blow dry air B which blows off from blower outlet 3. FIG. The number of blowable areas can be set to an arbitrary number of two or more. The air blowable area may be set so as to be lined up on the left and right. The air blowable area may be set so as to be lined up and down.

  The control unit 12 causes the display unit 5a to display a blowable area. The operation unit 5 receives a selection operation for selecting a blow target area from a plurality of blowable areas displayed on the display unit 5a. When the operation unit 5 receives a selection operation, the control unit 12 operates the wind direction changing unit so that air is blown to the air blowing target area selected by the selection operation.

  For example, the irradiation unit 17 emits light when the operation unit 5 receives a selection operation. When the irradiation unit 17 is attached to the wind direction plate 13, the irradiation unit 17 is irradiated in the same direction as the blowing direction of the dry air B. That is, the control part 12 changes the irradiation direction of the light from the irradiation part 17 by operating a wind direction change part so that light may be irradiated to the direction which shows a ventilation object area. The irradiation unit 17 serves as a means for visually indicating the air blowing target area to the user. Note that the irradiation unit 17 may emit light when the operation unit 5 receives a specific operation different from the selection operation.

  FIG. 4 is a diagram illustrating an example of display contents on the display unit in the first embodiment. FIG. 5 is a conceptual diagram illustrating an example of the operation of the dehumidifier in the first embodiment.

  FIG. 4 shows a state in which three air blowable areas are displayed on the display unit 5a, assuming that the entire range in which the dry air B can be blown is divided into left and right parts. The user selects an air blowing target area by performing a selection operation on the operation unit 5.

  FIG. 5 shows a state in which the middle blowable area of the three blowable areas in FIG. 4 is selected as the blow target area. In this case, the dry air B blown out from the dehumidifier is blown to the blow target area. Moreover, the light from the irradiation part 17 is irradiated with respect to the said ventilation target area.

  Hereinafter, the contents of control by the control unit 12 will be described in detail.

  For example, the control unit 12 operates the wind direction changing unit so that air is blown for a certain period of time with respect to the air blowing target area selected by the selection operation. The predetermined time may be set in advance or may be arbitrarily input using the operation unit 5. The control part 12 may stop operation | movement of the ventilation fan 7 and a wind direction change part, for example, after the said fixed time passes. Moreover, even if the control part 12 operates the wind direction change part so that it may blow with respect to the one part or all part of the ventilation possible area which is not selected as a ventilation object area after the said fixed time passes, for example. Good.

  The operation unit 5 can also accept a selection operation for selecting a plurality of air blowing target areas. When a plurality of air blowing target areas are selected, for example, the control unit 12 operates the wind direction changing unit so that the air is uniformly blown to all the air blowing target areas. On the other hand, when no air blowing target area is selected, the control unit 12 operates the air direction changing unit so that, for example, air is uniformly blown to all air blowing areas.

  The operation unit 5 can also accept a selection operation in which the user designates a priority order and selects a plurality of blowing target areas. The priority order is specified based on, for example, the order in which individual air blowing target areas are selected from a plurality of air blowing possible areas displayed on the display unit 5a. When a priority order is designated and a plurality of blowing target areas are selected, for example, the control unit 12 blows to a blowing target area with a higher priority for a certain period of time, and then moves to a blowing target area with the next highest priority. The wind direction changing unit is operated so that the air is blown for a certain time. That is, for example, the control unit 12 operates the wind direction changing unit so that each of the air blowing target areas is blown for a certain period of time in descending order of priority.

  The control unit 12 may control the display unit 5 a based on the dryness of the object to be dried detected by the infrared sensor 16. For example, the control unit 12 may change the display of the air blowing target area on the display unit 5a according to the change in the dryness detected from the air blowing target area by the infrared sensor 16. That is, the control unit 12 may cause the display unit 5a to display the progress of drying of the object to be dried existing in the air blowing target area. The display on the display unit 5a is changed by, for example, changing the color and blinking.

  For example, the control unit 12 may change the display of the blowable area on the display unit 5a according to a change in the dryness detected from the blowable area that is not selected as the blow target area. That is, the control unit 12 may cause the display unit 5a to display the progress of drying of the object to be dried that exists in the blowable area that is not the blowing target area.

  When a plurality of blowing target areas are selected without specifying the priority order or when no blowing target areas are selected, the control unit 12 determines the dryness of the object to be dried detected by the infrared sensor 16. Based on this, the wind direction changing unit may be operated. In this case, for example, the controller 12 changes the wind direction so that air is given priority over the air blowing target area or the air blowable area where the object to be dried, which is determined to be slow in drying based on the degree of dryness, exists. To work.

  The control unit 12 may operate the wind direction changing unit based on the dryness of the object to be dried detected by the infrared sensor 16 when the priority order is designated and a plurality of air blowing target areas are selected. In this case, for example, after the control unit 12 determines that the object to be dried existing in the air blowing target area is dry based on the dryness detected from the air blowing target area currently being blown, Next, a wind direction change part is operated so that it may blow with respect to another ventilation object area with a high priority. That is, the control unit 12 operates the wind direction changing unit so that, for example, an object to be dried existing in a blower target area with a higher priority is dried and then blown to a blower target area with the next highest priority.

  When it is determined that the object to be dried existing in the air blowing target area or the air blowing area is dried based on the dryness detected by the infrared sensor 16, the control unit 12 performs the air blowing possible area or the air blowing in the display unit 5a. By changing the display of the possible area, the user may be notified that the object to be dried has dried. Moreover, the control part 12 may alert | report to a user that the to-be-dried object dries by sounding a buzzer sound etc. from the speaker which is not illustrated. When it determines with the to-be-dried material which exists in all the ventilation object areas and all the ventilation possible areas having dried, the control part 12 stops the driving | operation of the ventilation fan 7 and the dehumidification part 10, for example.

  FIG. 6 is a flowchart illustrating an example of the operation of the dehumidifier in the first embodiment.

  The control unit 12 determines whether or not a selection operation for selecting the air blowing target area has been performed (step S101). When it is determined in step S101 that the selection operation has been performed, the control unit 12 determines whether or not the priority order is specified (step S102).

  When it is determined in step S102 that the priority order is designated, the control unit 12 operates the wind direction changing unit so that the air is blown to the blowing target area having the highest priority order (step S103). Thereafter, the control unit 12 determines whether or not a certain time has elapsed (step S104). When it determines with fixed time not having passed in step S104, the control part 12 continues the ventilation to the said ventilation object area.

  When it determines with fixed time having passed in step S104, the control part 12 determines whether there exists a ventilation target area with the next highest order (step S105). When it is determined in step S105 that there is a blower target area with the next highest rank, the control unit 12 operates the wind direction changing unit so as to blow air to the blower target area with the next highest order (step S106). Thereafter, the control unit 12 determines whether or not a certain time has elapsed (step S107). When it determines with fixed time not having passed in step S107, the control part 12 continues the ventilation to the said ventilation object area.

  When it is determined in step S107 that the predetermined time has elapsed, the control unit 12 performs the process of step S105. When it determines with there being no blowing target area with the next highest order by step S105, the control part 12 stops the driving | operation of the ventilation fan 7 and the dehumidification part 10, for example.

  When it determines with selection operation not being performed by step S101, the control part 12 operates a wind direction change part so that it ventilates uniformly (step S108). When performed following the process of step S101, in step S108, the air is uniformly blown to all the blowable areas.

  When it is determined in step S102 that the priority order is not specified, the control unit 12 performs the process of step S108. When performed subsequent to the process of step S102, in step S108, air is uniformly blown to all the air blowing target areas.

  After step S108, the control unit 12 determines whether or not a certain time has elapsed (step S109). When it determines with fixed time not having passed in step S109, the control part 12 continues uniform ventilation. When it determines with fixed time having passed in step S109, the control part 12 stops the driving | operation of the ventilation fan 7 and the dehumidification part 10, for example.

  Note that the processing of step S104, step S107, and step S109 need not determine the passage of time. The process of step S104, step S107, and step S109 may determine whether the to-be-dried object which exists in the ventilation object area currently blown or the ventilation possible area dried, for example.
