Embodiment 1.

Fig. 1 is a perspective view showing an external appearance of a dehumidifier 100 according to embodiment 1. Fig. 2 is a vertical sectional view showing the structure of the dehumidifier 100 according to embodiment 1. Here, the left-right direction on the paper surface in fig. 2 is taken as the front-rear direction of the dehumidifier 100. The vertical direction on the paper surface in fig. 2 is the vertical direction of the dehumidifier 100. That is, in fig. 2, the front direction of the paper surface is the left of the dehumidifier 100. In fig. 2, the back direction of the paper surface is the right direction of the dehumidifier 100.

The dehumidifier 100 includes a housing 1. The housing 1 is a part that serves as a casing of the dehumidifier 100. The frame 1 is formed in a vertically long box-like shape that can stand by itself, for example. In addition, the dehumidifier 100 may be provided with wheels 2, for example. For example, as shown in fig. 2, the wheels 2 are provided at the bottom of the frame 1. By the wheels 2, the dehumidifier 100 can move.

The housing 1 has a suction port 3 formed therein. The suction port 3 is an opening for taking in air into the housing 1. The suction port 3 is formed, for example, on the rear surface of the housing 1. Further, the housing 1 is formed with an air outlet 4. The air outlet 4 is an opening for blowing air from the inside of the housing 1 to the outside. The outlet 4 is formed, for example, in an upper portion of the front surface of the housing 1. The shape of the air outlet 4 is, for example, a rectangle extending in the left-right direction of the housing 1.

An air passage 5 is formed inside the housing 1. Air passage 5 is a space from suction port 3 to discharge port 4. Further, as an example of the blowing mechanism, the dehumidifier 100 includes an air blowing fan 6a and a fan motor 6. The blower fan 6a is a fan that generates an airflow in the air passage 5 from the suction port 3 toward the discharge port 4. A fan motor 6 is connected to the blower fan 6 a. The fan motor 6 is a motor that rotates the blower fan 6 a.

For example, as shown in fig. 2, the blower fan 6a and the fan motor 6 are provided inside the housing 1. The blower fan 6a is disposed in the air passage 5. In air passage 5 of the present embodiment, air is caused to flow from air inlet 3 to air outlet 4 by air sending fan 6 a. Air is blown out from the air outlet 4 by the blower fan 6 a. In air passage 5, the side having suction port 3 is the upstream side, and the side having discharge port 4 is the downstream side. That is, in the present embodiment, the air flows from the upstream side to the downstream side in the air passage 5.

As an example of a dehumidifying mechanism for removing moisture contained in air, the dehumidifier 100 includes a dehumidifying unit 7. The dehumidification section 7 is, for example, a device that condenses moisture in the air. The dehumidification section 7 discharges the condensed moisture. For example, the dehumidifying unit 7 drops the condensed moisture downward as liquid water. The air is dehumidified by the dehumidification section 7 by removing moisture from the air. The air dehumidified by the dehumidification section 7 becomes dry air.

The dehumidification section 7 is, for example, a device using a heat pump circuit. The dehumidification section 7 condenses moisture in the air by using, for example, an evaporator in the heat pump circuit. The dehumidifying unit 7 may be a desiccant type device, for example. The desiccant type device includes an adsorbent that adsorbs moisture in air and a heat exchanger. The moisture adsorbed by the adsorbent is condensed by the heat exchanger.

The dehumidification section 7 is provided inside the housing 1, for example. The dehumidifier 7 is disposed in the air duct 5. For example, the dehumidifying unit 7 is disposed between the suction port 3 and the blower fan 6 a. That is, the dehumidifying unit 7 of the present embodiment is disposed upstream of the blower fan 6 a. In the present embodiment, the suction port 3, the dehumidification section 7, the blower fan 6a, and the blow-out port 4 are arranged in this order from the upstream side to the downstream side.

The dehumidifier 100 includes a water storage unit 8. The water storage unit 8 is a part for storing the water discharged from the dehumidifying unit 7. For example, as shown in fig. 2, the reservoir 8 is an open-topped vessel. The water storage part 8 is provided inside the housing 1 and below the dehumidifying part 7. The water storage unit 8 is detachably provided from the housing 1, for example. The water storage unit 8 receives water dropped from the dehumidifying unit 7 from an opening in the upper part and stores the water.

In addition, the dehumidifier 100 may be provided with a filter 9. The filter 9 is provided inside the housing 1, for example. The filter 9 is provided to cover the suction port 3 from the inside of the housing 1. The filter 9 prevents dust from entering the inside of the housing 1.

The dehumidifier 100 includes an air direction changing unit 10. Fig. 3 is a sectional view showing the structure of the airflow direction changing unit 10 according to embodiment 1. The vertical and horizontal directions on the paper surface in fig. 3 correspond to the vertical and horizontal directions of the dehumidifier 100 of the present embodiment.

The airflow direction changing unit 10 is a portion that determines the direction in which air is blown out from the air outlet 4. Hereinafter, the direction in which the air is blown out from the air outlet 4 is referred to as the blowing direction. The blowing direction is changed by operating the airflow direction changing unit 10. The airflow direction changing unit 10 is disposed, for example, in the vicinity of the air outlet 4. The airflow direction changing unit 10 is an example of an airflow direction determining mechanism.

For example, as shown in fig. 1 and 3, the wind direction changing unit 10 includes a vertical louver 11 as an example of the first changing unit. The vertical louver 11 is formed in a shape matching the shape of the outlet 4, for example. The vertical louver 11 of the present embodiment is a rectangular frame-shaped portion extending in the horizontal direction of the housing 1. As an example, as shown in fig. 3, the vertical louver 11 has three plate-like portions extending in the left-right direction. The vertical louver 11 has, for example, a rectangular opening extending in the horizontal direction. The vertical louver 11 is formed to be rotatable about a horizontal axis.

The airflow direction changing unit 10 includes a first motor 12 for operating a vertical louver 11. The first motor 12 is provided inside the housing 1, for example. The first motor 12 rotates the vertical louver 11 via, for example, a gear 12a, a gear 12b, and a gear 12 c. When the up-down louver 11 is rotated, the direction of the opening of the up-down louver 11 is changed within a plane perpendicular to the axis in the left-right direction. This changes the blowing direction in the vertical direction.

As shown in fig. 1 and 3, for example, the wind direction changing unit 10 includes a left-right direction louver 13 as an example of the second changing unit. The left-right direction louver 13 has a plate-like portion extending in the up-down direction. For example, the left-right direction louver 13 has six plate-like portions extending in the up-down direction. Six plate-like portions extending in the vertical direction are arranged at equal intervals, for example. The left-right direction louver 13 is formed to be rotatable about a vertical axis. The left-right direction louver 13 is disposed inside the vertical direction louver 11, for example. The vertical louver 11 and the horizontal louver 13 are disposed so that, for example, the center positions in the horizontal direction coincide with each other.

The airflow direction changing unit 10 includes a second motor 14 for operating the left-right direction louver 13. The second motor 14 is provided inside the housing 1, for example. The airflow direction changing unit 10 includes a link 15. The link 15 is connected to the rear portion of the left-right direction louver 13, for example. 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 left-right direction louver 13 is rotated via the link 15. The blowing direction is changed in the left-right direction by rotating the left-right direction louver 13 about the vertical axis.

The left-right direction louver 13 is formed to be rotatable about a left-right direction axis. The link 15 is connected to the vertical louver 11. When the vertical louver 11 is operated, the link 15 is operated together with the vertical louver 11. When the link 15 is operated, the left-right direction louver 13 is operated together with the link 15. That is, when vertical louver 11 is operated, horizontal louver 13 is operated together with vertical louver 11. The left-right direction louver 13 operates in the same direction as the direction in which the up-down direction louver 11 operates.

The dehumidifier 100 includes a sensor unit 16. The sensor unit 16 is disposed inside the vertical louver 11, for example. The sensor unit 16 is disposed, for example, at the center in the lateral direction of the vertical louver 11.

Fig. 4 is a front view of the sensor unit 16 according to embodiment 1. Fig. 5 is a sectional view showing the structure of the sensor unit 16 of embodiment 1. The front direction of the paper of fig. 4 is the front direction of the sensor unit 16. The vertical direction on the paper surface of fig. 4 is the vertical direction of the sensor unit 16. In fig. 5, the right direction on the paper surface is the front direction of the sensor section 16, and the left direction on the paper surface is the back direction of the sensor section 16. The vertical direction on the paper of fig. 5 is the vertical direction of the sensor unit 16.

For example, as shown in fig. 1, 3, 4, and 5, the sensor unit 16 includes a sensor housing 17. The sensor case 17 is a part that serves as an outer frame of the sensor unit 16. For example, the sensor housing 17 has a cylindrical shape. The sensor housing 17 is formed to be rotatable about a vertical axis and a horizontal axis.

The sensor housing 17 is connected to the link 15 at, for example, the center of the vertical louver 11 in the lateral direction. The sensor housing 17 is connected to the left-right direction louver 13 via a link 15. The sensor housing 17 may be provided directly on the left-right direction louver 13 without the link 15, for example.

The sensor housing 17 is disposed with the front direction facing the blow-out direction. When the left-right direction louver 13 is operated, the sensor housing 17 is operated together with the left-right direction louver 13. The sensor housing 17 operates in the same direction as the direction in which the left-right direction louver 13 operates. When the blowing direction is changed, the front direction of the sensor case 17 also faces the changed blowing direction.

The sensor housing 17 may have a sensor window 17a on the front surface side, for example. The sensor window 17a is formed of a material having high infrared transmittance. The material having high infrared transmittance is, for example, a silicon wafer. The sensor window 17a is formed to transmit infrared rays radiated from a region to which air blown out from the air outlet 4 is blown. Hereinafter, the area to which the air blown out from the air outlet 4 is blown is referred to as an air-blowing area.

As an example of the surface temperature detection means, the sensor portion 16 may have a surface temperature detection portion 18. The surface temperature detecting unit 18 is a portion that detects the surface temperature of the target region in a non-contact state. The surface temperature detection unit 18 is formed by: the target area for detecting the surface temperature coincides with or is close to the blowout area.

The surface temperature detection unit 18 is provided inside the sensor housing 17. The surface temperature detection unit 18 is disposed on the back side of the sensor window 17 a. The surface temperature detector 18 uses a mechanism utilizing thermal electromotive force, for example. The surface temperature detecting unit 18 includes, for example, an infrared absorbing film and a thermistor. The infrared absorbing film of the surface temperature detecting section 18 absorbs the infrared rays transmitted through the sensor window 17 a.

The infrared absorbing film has a thermosensitive portion. The heat sensitive portion of the infrared absorbing film is heated by absorbing the infrared rays transmitted through the sensor window 17 a. The heat sensitive portion of the infrared absorbing film becomes the hot junction. The thermistor detects the temperature of a portion other than the thermosensitive portion of the infrared absorbing film, which is an example of the cold junction. The surface temperature detecting unit 18 detects the surface temperature of the area emitting the infrared rays absorbed by the infrared absorbing film, that is, the blown-out area, based on the temperature difference between the hot junction and the cold junction.

The blowing region is changed together with the blowing direction. The surface temperature detection unit 18 provided inside the sensor housing 17 operates together with the sensor housing 17. That is, surface temperature detecting unit 18 operates together with left-right direction louver 13. The surface temperature detection unit 18 can detect the surface temperature of the changed blowing region even when the blowing region is changed, for example.

As an example of the irradiation mechanism for irradiating visible light, the sensor unit 16 includes an irradiation unit 19. The irradiation unit 19 includes, for example, a light source 19a and a lens 19 b. The lens 19b is provided at a front portion of the sensor housing 17. The lens 19b is disposed below the sensor window 17a, for example. The light source 19a is provided on the back of the lens 19b and inside the sensor housing 17, for example.

The light source 19a irradiates visible light. The light source 19a is, for example, an LED. The light source 19a may be a laser diode, for example. The light source 19a is, for example, a light source having a luminous intensity of 1000mcd or more. The light source 19a irradiates, for example, green visible light. The visible light emitted by the light source 19a may be other than green, for example, orange.

The lens 19b condenses the visible light irradiated from the light source 19 a. The lens 19b is, for example, a lenticular lens of acrylic resin. The material of the lens 19b may be polycarbonate resin or glass, for example. The lens 19b may be a fresnel lens.

A portion between the light source 19a and the lens 19b in the sensor housing 17 is formed of, for example, a member that is transmissive to visible light irradiated with the light source 19 a. In addition, a portion between the light source 19a and the lens 19b in the sensor housing 17 may be opened, for example. The lens 19b is irradiated with visible light emitted from the light source 19 a.

The lens 19b condenses the visible light irradiated from the light source 19 a. The visible light condensed by the lens 19b is easily visible indoors, for example. The light source 19a and the lens 19b are provided so that the visible light condensed by the lens 19b is irradiated in the front direction of the sensor housing 17. That is, the visible light condensed by the lens 19b is irradiated in the blowing direction.

The visible light condensed by the lens 19b is irradiated to the outside of the housing 1. Here, a region irradiated with the visible light condensed by the lens 19b is set as the irradiation region 30. The light source 19a and the lens 19b are disposed such that the irradiation region 30 at a distance of 1m from the housing 1 is a circle having a diameter of 60mm, for example. The size and shape of the irradiation region 30 are not limited to this example.

The light source 19a and the lens 19b are provided in the sensor housing 17. The light source 19a and the lens 19b operate together with the sensor housing 17. That is, for example, even when the blowing direction is changed, the visible light condensed by the lens 19b is irradiated in the changed blowing direction.

The dehumidifier 100 includes a control device 20 and an operation unit 21. For example, as shown in fig. 2, the control device 20 is provided inside the housing 1. For example, as shown in fig. 1 and 2, the operation unit 21 is provided on the rear surface side of the upper surface of the housing 1. The control device 20 is connected to the operation unit 21.

The control device 20 is connected to each device provided in the dehumidifier 100. The control device 20 controls each device provided in the dehumidifier 100. The control device 20 is connected to, for example, the fan motor 6, the dehumidifying unit 7, the first motor 12, the second motor 14, and the irradiation unit 19. The controller 20 controls, for example, the fan motor 6, the dehumidifying unit 7, the first motor 12, the second motor 14, and the irradiation unit 19.

The control device 20 is connected to the surface temperature detection unit 18, for example. The surface temperature detection unit 18 converts information of the detected surface temperature into an electrical signal such as a voltage. The surface temperature detecting unit 18 outputs the converted electric signal to the control device 20. The control device 20 operates based on, for example, an electric signal from the surface temperature detection unit 18.

The operation unit 21 is a part for a user to operate the dehumidifier 100. The operation unit 21 includes, for example, an operation button 21a, a mode selection button 21b, a setting button 21c, and operation keys 21 d. The operation button 21a is used to start or stop the operation of the dehumidifier 100.

The mode selection button 21b is used to select an operation mode of the dehumidifier 100. The mode selection button 21b transmits a signal corresponding to an operation from the user to the control device 20, for example. The setting button 21c is used to set the dehumidifier 100. The setting button 21c transmits a signal to the control device 20 in response to an operation from the user, for example.

The operation key 21d is an example of an operation mechanism for transmitting an operation instruction. The operation key 21d is used to operate the airflow direction changing unit 10. The operation key 21d is, for example, a cross key. The operation key 21d transmits an operation instruction corresponding to an operation from the user to the control device 20. When receiving the operation instruction, the control device 20 operates based on the received operation instruction. The operation key 21d may be a key other than a cross key.

Fig. 6 is a diagram showing the control device 20 according to embodiment 1. Fig. 6(a) is a diagram showing an example of the configuration of the control device 20. For example, the control device 20 includes an operation control unit 20a, a storage unit 20b, a temperature determination unit 20c, and a setting unit 20 d. The operation control unit 20a is an example of a control mechanism that controls each device provided in the dehumidifier 100. The operation control unit 20a controls the first motor 12 and the second motor 14 based on, for example, an operation instruction from the operation key 21 d.

The storage unit 20b is an example of a storage mechanism. For example, a plurality of operation modes are preset in the storage unit 20 b. The operation control unit 20a selects one operation mode from the plurality of operation modes set in the storage unit 20b, for example, based on a signal from the mode selection button 21 b. The operation control unit 20a controls the fan motor 6, the dehumidifying unit 7, the first motor 12, the second motor 14, and the irradiation unit 19, for example, based on the selected operation mode.

In the storage unit 20b of the present embodiment, a fixed concentrated mode is stored as one of a plurality of operation modes. The fixed concentrating mode is an operation mode used when shoes, a small amount of clothes 31, and the like are concentrated and dried by the dehumidifier 100, for example.

The temperature determination unit 20c is a unit that determines the surface temperature based on the electric signal output from the surface temperature detection unit 18. The storage unit 20b stores information of a reference value of the surface temperature, for example. The temperature determination unit 20c determines the surface temperature based on, for example, the electrical signal from the surface temperature detection unit 18 and the information of the reference value stored in the storage unit 20 b.

The setting unit 20d is a part for setting the setting direction in the storage unit 20b based on a signal from the setting button 21 c. When the setting button 21c is pressed when the irradiation unit 19 irradiates visible light, for example, a signal is transmitted to the setting unit 20 d. Upon receiving the signal from the setting button 21c, the setting unit 20d sets the direction in which the irradiation unit 19 irradiates the visible light to the setting direction in the storage unit 20 b. The setting button 21c and the setting unit 20d are examples of a setting means for setting a setting direction.

Fig. 6(b) is a hardware configuration diagram showing an example of the configuration of the control device 20. The functions of the operation control unit 20a, the storage unit 20b, the temperature determination unit 20c, and the setting unit 20d of the control device 20 are realized by, for example, a processing circuit. The processing circuitry may also be dedicated hardware 200. The processing circuit may also include a processor 201 and a memory 202. A part of the processing circuit may be dedicated hardware 200, and further include a processor 201 and a memory 202. Fig. 6(b) shows an example in which a part of the processing circuit is formed as dedicated hardware 200 and includes a processor 201 and a memory 202.

Such as a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof, corresponding to a processing circuit with a portion of at least one dedicated hardware 200.

When the processing circuit includes at least one processor 201 and at least one memory 202, the functions of the operation control unit 20a, the storage unit 20b, the temperature determination unit 20c, and the setting unit 20d of the control device 20 are realized by software, firmware, or a combination of software and firmware.

The software and firmware are described as programs and stored in the memory 202. The processor 201 reads and executes the program stored in the memory 202, thereby realizing the functions of the respective sections. The processor 201 is also referred to as a CPU (Central Processing Unit), a Central Processing Unit, a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. For example, nonvolatile or volatile semiconductor memories such as RAM, ROM, flash memory, EPROM, and EEPROM, or magnetic disks, flexible disks, optical disks, high-density magnetic disks, mini disks, and DVDs correspond to the memory 202.

In this way, the processing circuit can realize the functions of the operation control unit 20a, the storage unit 20b, the temperature determination unit 20c, and the setting unit 20d of the control device 20 by hardware, software, firmware, or a combination thereof. The configuration of the dehumidifier 100 is not limited to the configuration in which the operation is controlled by a single controller 20. The dehumidifier 100 may be configured to control the operation by cooperation of a plurality of devices.

Next, an example of the operation of the dehumidifier 100 will be described. The dehumidifier 100 is used indoors, for example. For example, the dehumidifier 100 starts to operate by pressing the operation button 21 a. For example, the operation button 21a pressed by the user sends a signal to the operation control unit 20 a. Upon receiving a signal from the operation button 21a, the operation control unit 20a drives the fan motor 6 and the dehumidifying unit 7.

When the fan motor 6 is driven, the blower fan 6a rotates. The blower fan 6a generates an air flow. For example, as shown in fig. 2, the indoor air P is taken in from the air inlet 3 into the housing 1 by the airflow generated by the blower fan 6 a. The indoor air P is dehumidified by the dehumidifier 7 to become dry air Q. The dry air Q is blown out from the air outlet 4 into the room by the airflow generated by the blower fan 6 a. The blowing direction of the dry air Q is determined by the airflow direction changing unit 10. The dehumidifier 100 starts to operate as described above.

The user operates the mode selection button 21b after, for example, starting the operation of the dehumidifier 100 using the operation button 21 a. Hereinafter, as an example of the operation of the dehumidifier 100, an operation in the case where the user selects the fixed concentrated mode will be described.

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

Fig. 7 is a diagram showing the operation of the dehumidifier 100 according to embodiment 1. As shown in fig. 7, the irradiation region 30 is irradiated with visible light irradiated in the blowing direction of the dry air Q. The user operates the operation keys 21d while observing the irradiation region 30, for example. The operation key 21d transmits an operation instruction based on an operation from the user to the operation control unit 20 a. The operation control unit 20a controls the first motor 12 and the second motor 14 based on the received operation instruction. Thereby, vertical louver 11 and horizontal louver 13 operate. The blowing direction is changed by operating the vertical louver 11 and the horizontal louver 13.

When vertical louver 11 and horizontal louver 13 are operated, sensor housing 17 is also operated. In addition, the irradiation portion 19 provided in the sensor case 17 also operates. The irradiation unit 19 operates to irradiate light in the changed blowing direction. The irradiation region 30 moves in accordance with the change in the blowing direction. For example, as shown in fig. 7, the user operates the operation keys 21d while viewing the irradiation region 30 to irradiate the preset clothes 31. Thereby, the dry air Q is concentrated on the laundry 31.

Here, the user can press the setting button 21c in a state where the clothing 31 is irradiated with visible light, for example. The setting button 21c pressed by the user transmits a signal to the setting unit 20 d. Upon receiving the signal from the setting button 21c, the setting unit 20d sets the direction in which the irradiation unit 19 irradiates the visible light to the setting direction in the storage unit 20 b. When the set 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 set 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 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 detecting unit 18 converts information of the detected surface temperature into an electric signal. The surface temperature detecting unit 18 sends the converted electric signal to the temperature determining unit 20 c.

The temperature determination unit 20c determines the surface temperature based on the received electric signal and the information of the reference value stored in the storage unit 20b in advance. When the temperature determination 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. This ends the operation of the dehumidifier 100.

In the above-described embodiment, when the fixed concentrating mode is selected, the light source 19a of the irradiation section 19 irradiates visible light. The light source 19a may start irradiation of visible light at the same time as the operation of the dehumidifier 100 is started, for example. The light source 19a may stop the irradiation of the visible light at the same time as the setting button 21c is pressed or after a certain time has elapsed from the pressing of the setting button 21 c.

In the above-described embodiment, the user can easily recognize the blowing direction of the dry air Q by observing the irradiation region 30. Further, the user can easily change the blowing direction of the dry air Q in an arbitrary direction by using the operation keys 21 d. The user can change the blowing direction of the dry air Q in a state that is easy to understand by observing the irradiation region 30. The user can collect and dry the laundry 31 to be dried in advance without moving the laundry 31 to be dried in cooperation with the dehumidifier 100.

In the above embodiment, the user can concentrate the drying air Q in an arbitrary direction by operating the setting button 21 c. The drying air Q is not wasted and is reliably delivered to the laundry 31. According to this example, for example, wasteful electricity charges due to blowing air to an object that does not need to be dried can be reduced. The operation control unit 20a stops the fan motor 6 based on the detection result of the surface temperature detection unit 18. This further reduces wasteful electricity charges.

According to the above embodiment, the dehumidifier 100 can be obtained which can more easily recognize the blowing direction of the dry air Q and can more easily change the blowing direction of the dry air Q to an arbitrary direction. In the above embodiment, the operation of drying the laundry 31 is shown as an example, but the object to which the dry air Q is blown is not limited to the laundry 31. For example, the dehumidifier 100 can be used for drying a wet place in a room such as a wall or a floor of a bathroom.

The airflow direction changing unit 10, which is an example of the airflow direction determining means, may not include the vertical louver 11 and the horizontal louver 13. The structure of the airflow direction changing unit 10 may be, for example, a nozzle-shaped structure that can be operated in the vertical and horizontal directions, in addition to the above-described embodiments.

The irradiation unit 19 may not be provided in the sensor case 17, for example. Alternatively, the sensor housing 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 air direction changing unit 10 can operate independently. For example, the irradiation unit 19 may be operated by the control device 20 in accordance with the operation of the wind direction changing unit 10.

In the above embodiment, the operation keys 21d of the operation unit 21 are provided in the housing 1. The user can change the blowing direction of the dry air Q by an easy operation of the operation key 21d on the housing 1. In addition, the dehumidifier 100 may include a remote controller having an operation key 21d instead of the operation unit 21, for example. According to this example, the user can operate the dehumidifier 100 at a position away from the housing 1. The dehumidifier 100 may include both the operation unit 21 and a remote controller, for example.

Embodiment 2.

Next, embodiment 2 is explained. As with embodiment 1, the configuration of the dehumidifier 100 of the present embodiment is shown in fig. 1 to 6. The same configuration and operation as those in embodiment 1 will not be described. In the storage unit 20b of the present embodiment, a hunting focusing mode is stored as one of a plurality of operation modes. In the present embodiment, the irradiation region 30a is defined as a region to which visible light is irradiated.

The swing concentration mode is, for example, an operation mode used when drying the plurality of clothes 31 a. The swing concentration mode is an operation mode in which the dry air Q is blown out while changing the blowing direction. Hereinafter, in the present embodiment, the operation in the wobble concentration mode will be described.

For example, as in embodiment 1, after the user starts the operation of the dehumidifier 100 using the operation button 21a, the user operates the mode selection button 21 b. The operation control unit 20a selects, for example, the wobble concentration mode. When the swing concentration mode is selected, the operation control unit 20a causes the light source 19a of the irradiation unit 19 to irradiate visible light. The dry air Q is irradiated with visible light in the blowing direction. As in embodiment 1, the light source 19a may start irradiation of visible light at the same time as the operation of the dehumidifier 100, for example.

Fig. 8 is a diagram illustrating an operation of the dehumidifier 100 according to embodiment 2. The user moves the irradiation region 30a irradiated with the visible light irradiated from the irradiation section 19 by operating the operation keys 21 d. For example, as shown in fig. 8, the user presses the setting button 21c in a state where the left end clothing 31a is irradiated with visible light. When the setting button 21c is pressed, the direction in which the irradiation unit 19 irradiates the visible light is set to the first setting direction in the storage unit 20 b.

Next, for example, as shown in fig. 8, the user presses the setting button 21c in a state where the right clothing 31a is irradiated with visible light. When the setting button 21c is pressed, the direction in which the irradiation unit 19 irradiates the visible light is set to the second setting direction in the storage unit 20 b.

When the first setting direction and the second setting direction are 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 changed within a range between the first setting direction and the second setting direction. The dry air Q is blown out while swinging the vertical louver 11 and the horizontal louver 13. For example, as in embodiment 1, the dry air Q is blown out in a range between the first set direction and the second set direction until the surface temperature of the blowing region exceeds the reference value.

According to the present embodiment, the dry air Q is blown out to an arbitrary and wide range. The dry air Q is blown out while changing the blowing direction. According to the present embodiment, the dry air Q can be uniformly blown out to a wider range and an arbitrary object. In addition, as in embodiment 1, the user can easily recognize the blowing direction of the dry air Q. The user can specify the range of the blown dry air Q in an easily understandable state.

For example, a third setting direction and a fourth setting direction may be set in addition to the first setting direction and the second setting direction. The dehumidifier 100 of the present embodiment may be configured to change the blowing direction of the drying air Q in a range between a first setting direction, a second setting direction, a third setting direction, and a fourth setting direction, for example.

The dehumidifier 100 may be a dehumidifier in which embodiment 1 and embodiment 2 are combined. For example, the dehumidifier 100 may be configured to operate in both the fixed concentration mode shown in embodiment 1 and the swing concentration mode shown in embodiment 2.

The dehumidifier of the present invention is used for drying an arbitrary object.
