The left and right direction louver 13 has a plate-like portion that extends in the vertical direction. For example, the left and right direction louver 13 has six plate-like portions extending in the vertical direction. The six plate-like portions extending in the vertical direction are disposed, for example, at equal intervals. The louver 13 in the right and left direction is formed to be rotatable about an axis in the vertical direction. The left-right direction louver 13 is disposed, for example, inside the vertical louver 11 . The vertical direction louver 11 and the left-right direction louver 13 are disposed such that the positions in the center in the left-right direction coincide with each other.

The wind direction changing unit 10 has a second motor 14 for moving the left and right direction louvers 13. The second motor 14 is provided, for example, inside the casing 1. Further, the wind direction changing unit 10 has a link 15 . The link 15 is connected to, for example, the rear portion of the left and right direction louvers 13. The link 15 is connected to the second motor 14. That is, the left-right direction louver 13 and the second motor 14 are connected via the link 15. When the second motor 14 is driven, the louver 13 is rotated by the link 15 through the link 15 . The rotation of the louver 13 in the up-down direction is centered on the axis in the left-right direction, so that the blowing direction changes in the left-right direction.

Further, the left-right direction louver 13 is formed to be rotatable about an axis in the left-right direction. The link 15 is connected to the vertical louver 11. When the louver 11 moves up and down, the link 15 moves together with the up-and-down louver 11. When the link 15 moves, the left and right direction louver 13 and the link 15 move together. That is, when the louver 11 is moved up and down, the louver 13 and the louver 11 in the vertical direction move together.

The surface temperature detecting portion 18 has, for example, an infrared absorbing film and a thermistor. The infrared absorbing film of the surface temperature detecting portion 18 absorbs infrared rays that pass through the sensor window 17a.

The infrared absorbing film has a heat sensitive portion. The heat sensitive portion of the infrared absorbing film is heated by absorbing infrared rays that pass through the sensor window 17a. The heat sensitive portion of the infrared absorbing film is a warm junction. Further, the thermistor detects the temperature of a portion which is not a heat sensitive portion of the infrared absorbing film as an example of a cold junction. The surface temperature detecting unit 18 detects the surface temperature of the region (i.e., the blowing region) where the infrared ray absorbed by the infrared absorbing film is emitted from the temperature difference between the warm contact and the cold contact.

The blow-out area changes together with the blow-out direction. The surface temperature detecting portion 18 provided inside the sensor case 17 moves together with the sensor case 17. That is, the surface temperature detecting portion 18 moves together with the left-right direction louver 13.

The indoor air P is dehumidified by the dehumidifying unit 7 into dry air Q. The dry air Q is blown out from the air outlet 4 into the room by the air flow generated by the blower fan 6a. The blowing direction of the dry air Q is determined by the wind direction changing unit 10. As described above, the dehumidifier 100 starts operating.

The user operates the mode selection button 21b after the operation of the dehumidifier 100 is started by the operation button 21a, for example. Hereinafter, an operation when the user selects the fixed concentration mode will be described as an example of the operation of the dehumidifier 100.

The operation control unit 20a selects the fixed concentration mode based on the signal from the mode selection button 21b. When the fixed concentration mode is selected, the operation control unit 20a causes the light source 19a of the irradiation unit 19 to illuminate the visible light. The visible light is collected by the lens 19b. The visible light collected by the lens 19b is irradiated toward the blowing direction of the dry air Q.

Fig. 7 is a view showing the operation of the dehumidifier 100 of the first embodiment. As shown in Fig. 7, the visible light that is irradiated toward the blowing direction of the dry air Q illuminates the irradiation region 30. For example, the user operates the operation button 21d while looking at the irradiation area 30. The operation button 21d transmits an operation instruction based on the user's operation 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 louver 11 and the left-right direction louver 13 move up and down. The louver 11 and the left and right louver 13 are moved in the vertical direction to change the blowing direction.

When the up-and-down louver 11 and the left-right direction louver 13 move, the sensor case 17 also moves together. Further, the illuminating portion 19 provided in the sensor case 17 also moves. The illuminating unit 19 moves to illuminate the light toward the changed blowing direction. The irradiation area 30 moves in accordance with the change in the blowing direction. The user operates the operation button 21d while looking at the irradiation area 30, for example, as shown in FIG. In order to shine the clothes 31 set in advance. Thereby, the dry air Q is concentrated on the clothes 31.

Here, for example, the user may press the setting button 21c 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 irradiation unit 19 emits visible light in the storage unit 20b as the setting direction. 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 to fix the blowing direction in the setting direction.

When the blowing direction is fixed in the set direction, the dry air Q continues to blow out in the set direction for a certain period of time. When the dry air Q is blown out, the surface temperature detecting portion 18 detects the surface temperature of the blow-out region. The surface temperature detecting unit 18 converts the information of the detected surface temperature into an electrical signal. The surface temperature detecting unit 18 transmits the converted electric signal to the temperature determining unit 20c.

The temperature determining unit 20c determines the surface temperature based on the received electrical signal and the information of the reference value previously stored in the memory unit 20b. When the temperature determining unit 20c determines that the surface temperature of the blowing 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 ended.

In the above embodiment, when the fixed concentration mode is selected, the light source 19a of the illuminating unit 19 illuminates visible light. The light source 19a may also start to illuminate visible light, for example, while the operation of the dehumidifier 100 is started. Further, for example, the light source 19a may stop the irradiation of visible light after a predetermined period of time has elapsed after the setting button 21c is pressed or after the setting button 21c is pressed.

In the above embodiment, the user can easily recognize the blowing direction of the dry air Q by observing the irradiation area 30. In addition, the user can easily direct the direction in which the dry air Q is blown toward the arbitrary side by operating the button 21d. Change to. The user can change the blowing direction of the dry air Q in an easily understandable state by observing the irradiation area 30. The user does not need to cooperate with the dehumidifier 100 to move the clothes 31 to be dried, and the clothes 31 that have been air-dried in advance can be concentrated and dried.

In the above embodiment, the user can concentrate the dry air Q in any direction by operating the setting button 21c. The dry air Q is blown to the clothes 31 without any waste. In this example, it is possible to reduce the wasted electricity cost caused by, for example, blowing air to an object that does not need to be dried. Further, the operation control unit 20a stops the fan motor 6 based on the detection result of the surface temperature detecting unit 18. Thereby, the wasteful electricity bill is further reduced.

According to the above-described embodiment, the dehumidifier 100 is obtained, it is easier to recognize the direction in which the dry air Q is blown, and it is easier to change the direction in which the dry air is blown toward any direction. In the above-described embodiment, the operation of drying the clothes 31 is shown as an example, but the object to be blown by the dry air Q is not limited to the clothes 31. For example, the dehumidifier 100 can be used when a wall of a bathroom or a floor such as a floor is wetted in a room.

The wind direction changing unit 10 as an example of the wind direction determining device may not include the vertical louver 11 and the left and right louver 13 . In addition to the above-described embodiment, the structure of the wind direction changing portion 10 may be, for example, a nozzle-like structure that can move in the up, down, left, and right directions.

Further, the illuminating unit 19 may not be provided, for example, to the sensor case 17. Alternatively, the sensor housing 17 may not be connected to the connecting rod 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 can 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 button 21d of the operation unit 21 is provided in Housing 1. The user can change the blowing direction of the dry air Q by operating the easy operation of the operation button 21d on the casing 1. Further, for example, the dehumidifier 100 may not include the operation unit 21, and may be provided with a remote controller having an operation button 21d. In this example, the user can operate the dehumidifier 100 at a position away from the housing 1. Further, for example, the dehumidifier 100 may be provided with both the operation unit 21 and the remote controller.
