For example, the user operates the operation key 21d while looking at the irradiation area 30. The operation key 21d transmits an operation instruction based on an operation from the user to the operation control unit 20a. The operation control unit 20a controls the first motor 12 and the second motor 14 based on the received operation instruction. Thereby, the up-down direction louver 11 and the left-right direction louver 13 move. The blowing direction is changed by moving the vertical louver 11 and the horizontal louver 13.

When the vertical louver 11 and the horizontal louver 13 move, the sensor case 17 also moves. The irradiation unit 19 provided in the sensor case 17 also moves. The irradiation unit 19 moves so as to irradiate light in the changed blowing direction. The irradiation area 30 moves according to the change of the blowing direction. The user operates the operation key 21d while observing the irradiation area 30, as shown in FIG. Thereby, the dry air Q concentrates on the clothes 31.

Here, the user may press the setting button 21c, for example, while the clothes 31 are illuminated by visible light. The setting button 21c pressed by the user transmits a signal to the setting unit 20d. When receiving the signal from the setting button 21c, the setting unit 20d sets the direction in which the visible light is irradiated by the irradiation unit 19 as the setting direction in the storage unit 20b. When the setting direction is set in the storage unit 20b, the operation control unit 20a controls the first motor 12 and the second motor 14 so that the blowing direction is fixed in the setting direction.

When the blowing direction is fixed in the setting direction, the dry air Q continues to be blown in the setting direction for a certain time. When the dry air Q is blown out, the surface temperature detection unit 18 detects the surface temperature of the blowing region. The surface temperature detector 18 converts the detected surface temperature information into an electrical signal. The surface temperature detection unit 18 transmits the converted electrical signal to the temperature determination unit 20c.

The temperature determination unit 20c determines the surface temperature based on the received electrical signal and reference value information stored in advance in the storage unit 20b. When it is determined by the temperature determination unit 20c that the surface temperature of the blowout region exceeds the reference value, the operation control unit 20a stops the fan motor 6 and the dehumidifying unit 7. Thereby, the operation of the dehumidifier 100 is completed.

In the above embodiment, the light source 19a of the irradiation unit 19 emits visible light when the fixed concentration mode is selected. For example, the light source 19a may start irradiation with visible light simultaneously with the start of the operation of the dehumidifier 100. For example, the light source 19a may stop the irradiation of visible light at the same time when the setting button 21c is pressed or after a certain time has elapsed since the setting button 21c was pressed.

In the above embodiment, the user can easily recognize the blowing direction of the dry air Q by looking at the irradiation region 30. Further, the user can easily change the blowing direction of the dry air Q to an arbitrary direction by the operation key 21d. The user can change the blowing direction of the dry air Q in an easy-to-understand state by looking at the irradiation region 30. The user can concentrate and dry the clothes 31 previously dried without moving the clothes 31 to be dried according to the dehumidifier 100.

In the above embodiment, the user can concentrate the dry air Q in an arbitrary direction by operating the setting button 21c. The dry air Q is reliably sent toward the clothes 31 without waste. If it is this example, the useless electricity bill by the ventilation to the thing which does not need to be dried will be reduced, for example. Further, the operation control unit 20 a stops the fan motor 6 based on the detection result of the surface temperature detection unit 18. Thereby, useless electricity bill is further reduced.

According to the above embodiment, it is possible to obtain the dehumidifier 100 that can more easily recognize the blowing direction of the dry air Q and can easily change the blowing direction of the dry air Q to an arbitrary direction. In addition, although the operation | movement which dries the clothes 31 was shown as an example in the said Example, the object from which the dry air Q is blown off is not restricted to the clothes 31. FIG. For example, the dehumidifier 100 can also be used when drying indoor wet places such as bathroom walls and floors.

The wind direction changing unit 10 that is an example of the wind direction determining unit may not include the vertical direction louver 11 and the horizontal direction louver 13. The structure of the wind direction changing unit 10 may be, for example, a nozzle-like structure that can move in the vertical and horizontal directions other than the above-described embodiment.

Moreover, the irradiation part 19 does not need to be provided in the sensor case 17, for example. Alternatively, the sensor case 17 may not be connected to the link 15. For example, the dehumidifier 100 may be configured such that the irradiation unit 19 and the wind direction changing unit 10 can operate independently. For example, the irradiation unit 19 may be moved by the control device 20 in accordance with the movement of the wind direction changing unit 10.

In the above embodiment, the operation key 21d of the operation unit 21 is provided on the housing 1. The user can change the blowing direction of the dry air Q by an easy operation of operating the operation key 21d on the housing 1. In addition, the dehumidifier 100 may be provided with the remote controller which has the operation key 21d instead of the operation part 21, for example. In this example, the user can operate the dehumidifier 100 at a position away from the housing 1. Moreover, the dehumidifier 100 may be provided with both the operation part 21 and the remote controller, for example.

Embodiment 2. FIG.

The description of the same configuration and operation as in Embodiment 1 is omitted. FIG. 8 is a diagram illustrating the operation of the dehumidifier 100 according to the second embodiment.

In the present embodiment, the lens 19b is a lens that splits visible light from the light source 19a into first visible light and second visible light. Thereby, the irradiation region 30 is divided into a first region 30a and a second region 30b. The first region 30a is a region irradiated with the first visible light. The second region 30b is a region irradiated with the second visible light. The first visible light has a luminous intensity higher than that of the second visible light, for example. That is, the first region 30a has higher illuminance than the second region 30b. The lens 19b in the present embodiment is an example of a dividing unit.

The first region 30a and the second region 30b are circular regions as shown in FIG. 8, for example.

In the present embodiment, the light source 19a and the lens 19b are formed and arranged so that the first region 30a is positioned inside the second region 30b. The first region 30a is located at the center of the second region 30b, for example. The first region 30a brighter than the second region 30b represents the blowing direction of the dry air Q. The user can easily recognize the blowing direction of the dry air Q by looking at the first region 30a.

Further, the light source 19a and the lens 19b are formed and arranged so that the blowing area of the dry air Q and the second area 30b are coincident with or close to each other. That is, the dry air Q blown out from the blower outlet 4 hits the second region 30b. The second area 30b represents a blowing area of the dry air Q. The user can recognize the blowing area of the dry air Q by looking at the second area 30b.

The user of the dehumidifier 100 according to the present embodiment can move the irradiation region 30 by operating the operation key 21d as in the first embodiment. The user can move the first region 30a and the second region 30b while viewing the first region 30a and the second region 30b. That is, the user can change the blowing direction and the blowing area of the dry air Q while recognizing the blowing direction and the blowing area of the dry air Q. For example, the user operates the operation key 21d so that the clothes 31 are located inside the second region. Thereby, the clothes 31 are evenly dried.

The shape and size of the first region 30a and the second region 30b are not limited to this example. For example, the shape of the second region 30b may be a rectangle. The dehumidifier 100 of the present embodiment may be operated in the fixed concentration mode shown in the first embodiment.
