The blowing direction of the dry air Q is determined by the wind direction changing unit 10. As described above, the dehumidifier 100 starts to operate.

The user operates the mode selection button 21b after the operation of the dehumidifier 100 is started by the operation button 21a, for example. The following describes the operation when the user selects the fixed focus mode as an example of the operation of the dehumidifier 100.

The motion control unit 20a selects a fixed focus mode based on a signal from the mode selection button 21b. The operation control unit 20 a irradiates the light source 19 a of the irradiation unit 19 with visible light when the fixed focus mode is selected. 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 diagram showing the operation of the dehumidifier 100 according to the first embodiment. As shown in FIG. 7, the visible light irradiated toward the blowing direction of the dry air Q irradiates the irradiation area 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 a user's operation to the motion 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 louver 11 and the left-right louver 13 are moved. With up and down direction louver 11 and left and right direction The louver 13 moves to change the blowing direction.

When the up and down louver 11 and the left and right louver 13 move, the sensor case 17 also moves together. In addition, the irradiation section 19 provided in the sensor case 17 also moves. The irradiating part 19 moves to irradiate light in the changed blowing direction. The irradiation area 30 moves in accordance with the change in the blowing direction. The user, while looking at the irradiation area 30, for example, as shown in FIG. 7, operates the operation button 21d to illuminate the clothes 31 provided in advance. Thereby, the dry air Q is concentrated on the clothes 31.

Here, for example, the user may press the setting button 21c in a state where 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 the setting unit 20d receives a signal from the setting button 21c, the setting unit 20d sets the direction in which the irradiating unit 19 emits visible light to the storage unit 20b as the setting direction. When the setting direction is set in the memory unit 20b, the operation control unit 20a controls the first motor 12 and the second motor 14 to fix the blowing direction to the setting direction.

When the blowing direction is fixed in the set direction, the dry air Q is continuously blown in the set direction for a certain period of time. When the dry air Q is blown out, the surface temperature detection unit 18 detects the surface temperature of the blown-out area. The surface temperature detection unit 18 converts the detected surface temperature information into an electrical signal. The surface temperature detection section 18 transmits the converted electrical signal to the temperature determination section 20c.

The temperature determination unit 20c determines the surface temperature based on the received electrical signal and information of a reference value stored in the memory unit 20b in advance. When the temperature determination unit 20c determines that the surface temperature of the blowing area exceeds a reference value, the operation control unit 20a stops the fan motor 6 and the dehumidification unit 7. Thereby, the operation of the dehumidifier 100 is terminated.

In the above embodiment, when the fixed focus mode is selected, the irradiation section The light source 19a of 19 emits visible light. For example, when the operation of the dehumidifier 100 is started, the light source 19a may start to emit visible light. In addition, for example, the light source 19a may stop irradiation of visible light while the setting button 21c is being pressed, or after a certain period of time has elapsed after the setting button 21c is pressed.

In the above embodiment, the user can easily identify the blowing direction of the dry air Q by observing the irradiation area 30. In addition, the user can easily change the blowing direction of the dry air Q to an arbitrary direction by operating the button 21d. 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 move the clothes 31 to be dried in cooperation with the dehumidifier 100, and can collectively dry the clothes 31 air-dried beforehand.

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 blown to the clothes 31 without any waste. In this example, it is possible to reduce wasteful electricity costs caused by, for example, supplying air to a thing that does not need to be dried. The operation control unit 20 a stops the fan motor 6 based on the detection result of the surface temperature detection unit 18. This reduces wasteful electricity bills.

According to the embodiment described above, the dehumidifier 100 is obtained, it is easier to recognize the blowing direction of the dry air Q, and it is easier to change the direction in which the dry air Q is blown out to an arbitrary direction. In the above 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 in a place where the interior of a house such as a bathroom wall and a floor is wet.

The wind direction changing unit 10 as an example of the wind direction determining device may not include the vertical louver 11 and the horizontal louver 13. In addition to the above examples In addition, the structure of the wind direction changing unit 10 may be, for example, a nozzle-like structure capable of moving up, down, left, and right.

The irradiating portion 19 may not be provided on the sensor case 17, for example. Alternatively, the sensor case 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 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 keys 21 d of the operation section 21 are provided on the housing 1. The user can change the blowing direction of the dry air Q by an easy operation of the operation button 21 d on the housing 1. In addition, for example, the dehumidifier 100 may not include the operation unit 21, but may include a remote controller having an operation button 21d. In this example, the user can operate the dehumidifier 100 from a position away from the casing 1. In addition, for example, the dehumidifier 100 may include both the operation unit 21 and a remote controller.

Embodiment 2.

Next, Embodiment 2 will be described. The configuration of the dehumidifier 100 according to this embodiment is the same as that of the first embodiment, and is shown in FIGS. 1 to 6. The description of the same configuration and operation as those of the first embodiment is omitted. Fig. 8 is a diagram showing the operation of the dehumidifier 100 according to the second embodiment.

In this embodiment, the lens 19b is a lens that divides visible light from the light source 19a into first visible light and second visible light. Thereby, the irradiation area 30 is divided into a first area 30a and a second area 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. For example, the luminosity of the first visible light is greater than that of the second visible light. That is, the illuminance of the first region 30a is higher than that of the second region 30b. The lens 19b in this embodiment is an example of a division device.

The first region 30a and the second region 30b are, for example, circles shown in FIG. 8 Shaped area. For example, the light source 19a and the lens 19b are formed and arranged such that the first region 30a is a circle having a diameter of 60 mm. In addition, for example, the light source 19a and the lens 19b are formed and arranged such that the second region 30b is a circle having a diameter of 800 mm.

The light source 19a and the lens 19b in this embodiment are formed and arranged so that the first region 30a is positioned inside the second region 30b. The first region 30a is located, for example, in the center of the second region 30b. The first region 30a, which is brighter than the second region 30b, indicates the blowing direction of the dry air Q. The user can easily understand the blowing direction of the dry air Q by observing the first area 30a.

In addition, the light source 19a and the lens 19b are formed and arranged so that the blow-out area of the dry air Q and the second area 30b coincide or are close to each other. That is, the dry air Q blown from the blow-out port 4 is blown to the second region 30b. The second area 30b indicates a blowing area of the dry air Q. By observing the second area 30b, the user can recognize the blowing area of the dry air Q.

The user of the dehumidifier 100 of this embodiment can move the irradiation area 30 by operating the operation button 21d as in the first embodiment. The user can move the first area 30a and the second area 30b while visually recognizing them. That is, the user can change the blowing direction and the blowing area of the dry air Q in a state where the blowing direction and the blowing area of the dry air Q are recognized. For example, the user operates the operation button 21d so that the clothes 31 are located inside the second area. Thereby, the clothes 31 are uniformly 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 rectangular. In addition, the dehumidifier 100 according to the present embodiment can also be operated in the fixed concentrated mode shown in the first embodiment.

The dehumidifier 100 according to this embodiment includes a plurality of light sources 19a. The visible light source 19a may be selected by the user. For example, the user may select the light source 19 a that emits visible light by operating the operation unit 21. For example, when the user only wants to recognize the blowing direction of the dry air Q, the user may operate the operation unit 21 so that only the first area 30a is illuminated. In this example, only one of the first area 30a indicating the blowing direction of the dry air Q and the second area 30b indicating the blowing area of the dry air Q may be illuminated.
