The control unit 12 is electrically connected to the operation unit 5, the display unit 5a, the air-sending fan 7, the temperature sensor 8, the humidity sensor 9, the dehumidification unit 10, and the water level sensor 11.

The operation unit 5 accepts the operation of the user of the dehumidifier. The operation accepted by the operation unit 5 is, for example, an operation of turning on or off the power of the dehumidifier. The operation accepted 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 use status of the dehumidifier by, for example, characters, symbols, and images. The display unit 5a may display information such as lighting and blinking of a lamp.

The air-supply fan 7 generates an air flow from the air inlet 2 to the air outlet 3 in the air path. That is, the blower fan 7 functions as a blower section that blows air sucked from the suction port 2 into the inside of the housing 1 through the blowout port 3.

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

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

The dehumidifier 10 is only required to remove moisture from the air and condense it. The dehumidifying unit 10 may be a person that condenses moisture in the air using, for example, an evaporator in a heat pump circuit. The dehumidifying unit 10 may be a desiccant system that uses a heat exchanger to condense moisture in the air removed by the adsorbent, for example.

The louver 4 is provided so as to be rotatable up and down within a fixed angle range. The wind vane driving motor 14 and the blind 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 irradiating 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 fixed angular range. That is, the wind direction board driving motor 14 changes the direction of the wind direction board 13 laterally. Each of the wind direction plates 13 may face a different direction. The louver drive motor 15 rotates the louver 4 up and down within a fixed angle range. That is, the blind driving motor 15 changes the direction of the blind 4 in the vertical direction. The direction of the dry air B blown from the air outlet 3 is changed in accordance with the directions of the wind directing 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 mounted on the wind direction plate 13, it detects the surface temperature of an object located in the same direction as the direction of the wind direction plate 13 and the shutter 4. in In this case, the range in which the surface temperature can be detected by the infrared sensor 16 is the same as the range in which the dry air B blown out from the blowout port 3 can be sent out. The infrared sensor 16 is, for example, a dryness detection unit that detects the dryness of a to-be-dried object such as laundry to be dried indoors. The dryness is, for example, the surface temperature of the object to be dried or a value calculated from the surface temperature. A signal indicating a detection result of the infrared sensor 16 is transmitted to the control unit 12.

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

The irradiating unit 17 irradiates light. The 17 series uses, for example, an LED light source or a laser light source. When the irradiating part 17 is attached to the wind direction board 13, it irradiates light in the same direction as the direction of the wind direction board 13 and the louver 4. In this case, the range in which the light from the irradiation section 17 can be irradiated is the same as the range in which the dry air B blown out from the blowout port 3 can be sent out.

The control unit 12 controls the operations of the wind vane driving motor 14, the blind driving motor 15 and the irradiation unit 17 based on the operations accepted by the operation unit 5. The control unit 12 controls the operations of the display unit 5a, the air-sending fan 7, the dehumidifying unit 10, the wind vane driving motor 14, the blind driving motor 15, and the irradiation unit 17 based on the detection result of the infrared sensor 16.

The control unit 12 sets a plurality of air-supplyable areas as a unit that divides the entire range of the dry air B that can be sent out from the air outlet 3. The number of air supply regions can be set to any number of two or more. The air supply area may be set to be aligned in the left and right directions. The air supply area may be set up and down.

The control unit 12 displays a blowable area on the display unit 5a. The operation unit 5 accepts a selection operation for selecting a ventilation target region from a plurality of ventilation possible regions displayed on the display unit 5a. When the control unit 12 accepts the selection operation in the operation unit 5, the control unit 12 operates the wind direction changing unit so as to supply air to the air supply target area selected by the selection operation.

The irradiating unit 17 irradiates light when, for example, the operating unit 5 accepts a selection operation. When the irradiating part 17 is attached to the wind direction board 13, it irradiates in the same direction as the blowing direction of the dry air B. That is, the control unit 12 operates the wind direction changing unit to change the irradiation direction of the light from the irradiation unit 17 so as to irradiate the light in the direction indicating the area to be blown. The irradiating unit 17 functions as a means for visually indicating a region to be blown to a user. In addition, the irradiation unit 17 may irradiate light when the operation unit 5 receives a specific operation different from the selection operation.

Fig. 4 is a diagram showing an example of display contents of a display unit according to the first embodiment. Fig. 5 is a schematic diagram showing an example of the operation of the dehumidifier of the first embodiment.

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

Fig. 5 shows a state in which the air-supplyable region in the center of the three air-supplyable regions of Fig. 4 is selected as the air-ventilation target region. In this case, the dry air B blown from the dehumidifier is blown to the area to be blown. In addition, the light from the irradiating unit 17 is irradiated to the air blowing target area.

The control content of the control unit 12 will be described in detail below.

The control unit 12 operates the wind direction changing unit, for example, so as to blow air only to a fixed period of time for the air supply target area selected by the selection operation. The fixed time may be a preset person or may be arbitrarily input using the operation unit 5. The control unit 12 may stop the operations of the blower fan 7 and the wind direction changing unit after the fixed time elapses, for example. In addition, the control unit 12 may operate the wind direction changing unit after the fixed time has elapsed, for example, to blow a part or all of the air-supplyable area that is not selected as the air-ventilation area.

The operation unit 5 may also accept a selection operation for selecting a plurality of air supply target areas. When the control unit 12 selects a plurality of air supply target areas, for example, the air flow direction changing unit is operated so as to uniformly blow air to all the air supply target areas. On the other hand, when none of the air supply target areas is selected, the control unit 12 operates the wind direction changing unit so as to uniformly blow air to all the air supply target areas, for example.

The operation unit 5 can also accept a selection operation in which the user designates a priority order to select a plurality of air supply target areas. The priority order is specified based on, for example, the order in which the respective air supply target areas are selected from the plurality of air supply available areas displayed on the display section 5a. The control unit 12 selects a plurality of air supply target areas in a given priority order. For example, after the air is supplied to the air supply target area with a higher priority for a fixed time, the air is then supplied to the air supply target area with a higher priority for a fixed time The mode causes the wind direction changing unit to operate. That is, the control unit 12 operates the wind direction changing unit, for example, so as to blow air for each fixed time in the order of higher priority to each air blowing target area.

The control unit 12 is also detected based on the infrared sensor 16 The dryness control display part 5a of the object to be dried is displayed. The control unit 12 may change the display of the air supply target area on the display unit 5a in response to a change in the dryness detected from the air supply target area by the infrared sensor 16. That is, the control unit 12 may cause the display unit 5a to display the progress of the drying of the object to be dried existing in the air supply target area. The change displayed on the display section 5a is performed by, for example, changing color, flickering, or the like.

The control unit 12 may change the display of the air-supplyable region on the display unit 5a in response to a change in dryness detected in the air-supplyable region that has never been selected as the air-supplying region. 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-supplyable area that is not the air-supply target area.

The control unit 12 may also select a plurality of air supply target areas without specifying a priority order or a case where none of the air supply target areas are selected. Based on the dryness of the object to be dried detected by the infrared sensor 16, The wind direction changing unit is operated. In this case, for example, the control unit 12 operates the wind direction changing unit such that the air is preferentially blown to a target area or a blowable area in which the object to be dried has a slow progress in drying according to the degree of drying.

In the case where the control unit 12 selects a plurality of air supply target areas in a designated priority order, 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. In this case, for example, the control unit 12 determines the priority of the ventilation target area after determining that the dried object existing in the ventilation target area is dried based on the dryness detected from the current ventilation target area. The method of blowing air in the next-highest air-supply target area causes the wind direction changing unit to operate. That is, the control unit 12 has a higher priority, for example.

After the to-be-dried substance existing in the air supply target area dries, the air direction changing unit is operated by blowing air to the air supply target area with the highest priority. It is also possible that the control unit 12 changes the air supply target area on the display portion 5a when it is determined that the dried object exists in the air supply target area or air supply area based on the dryness detected by the infrared sensor 16. Or the display of the blowable area, thereby notifying the user that the dried object is dry. In addition, the control unit 12 notifies the user that the dried object is dry by making a beep sound or the like from a speaker (not shown). The control unit 12 determines that the objects to be dried exist in all the air supply target areas or all the air supply possible areas, and for example, the air supply fan 7 and the dehumidifying unit 10 are stopped.

Then, the control unit 12 determines whether a fixed time has elapsed (step S104). If it is determined in step S104 that the fixed time has not elapsed, the control unit 12 continues the air supply to the air supply target area.

When it is determined in step S104 that the fixed time has elapsed, the control unit 12 determines whether there is an air supply target region with a higher priority order (step S105). In the case where it is determined in step S105 that there is an air supply target area with the highest priority, the control unit 12 causes the air to be blown to the air supply target area with the next highest priority. Operate to the change unit (step S106). Then, the control unit 12 determines whether a fixed time has elapsed (step S107). If it is determined in step S107 that the fixed time has not elapsed, the control unit 12 continues the air supply to the air supply target area.

When it is determined in step S107 that the fixed time has elapsed, the control unit 12 performs the process of step S105. If it is determined in step S105 that there is no priority area for the air supply target, the control unit 12 stops the air supply fan 7 and the dehumidification unit 10.

When it is determined in step S101 that the selection operation has not been performed, the control unit 12 operates the wind direction changing unit in such a manner that air is uniformly supplied (step S108). In the case where the process subsequent to step S101 is performed, in step S108, the air is uniformly blown to all the air-supplyable regions.

When it is determined in step S102 that the priority order is not specified, the control unit 12 performs the process of step S108. In the case where the process subsequent to step S102 is performed, in step S108, the air is uniformly blown to all the air-supplyable regions.

After step S108, the control unit 12 determines whether a fixed time has elapsed (step S109). When it is determined in step S109 that the fixed time has not elapsed, the control unit 12 continues the uniform air supply. When it is determined in step S109 that the fixed time has elapsed, the control unit 12 stops the blower fan 7 and the dehumidifying unit 10, for example.

In addition, the processing in steps S104, S107, and S109 may not be the elapse of the judgment time. In the processing of steps S104, S107, and S109, it is also possible to determine, for example, whether or not the object to be dried exists in the current air supply target area or air supply available area.
