  The dehumidifier 100 includes a wind direction changing unit 10. FIG. 5 is a cross-sectional view showing the configuration of the wind direction changing unit 10 according to the first embodiment. FIG. 5 schematically shows a part of the cross section of the dehumidifier 100 at the position BB in FIG. The up, down, left, and right directions on the paper surface in FIG. 5 correspond to the up, down, left, and right directions on the paper surface in FIG.

  The wind direction changing unit 10 determines the direction in which air is sent 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 moving the wind direction changing unit 10. The blowing direction is determined by the state of the wind direction changing unit 10. The wind direction changing unit 10 of the present embodiment is an example of a wind direction determining unit. The wind direction changing unit 10 is arranged near the air outlet 4.

  The wind direction changing unit 10 has a vertical louver 11 as an example of a first changing unit that changes the direction in which air is sent from the air outlet 4 to the vertical direction. The vertical louver 11 is formed in conformity with the shape of the air outlet 4. The up-down louver 11 of the present embodiment is a rectangular frame-shaped member extending in the left-right direction. As an example, the vertical louver 11 includes, as shown in FIG. 5, three plate-shaped members extending in the horizontal direction. The up-down louver 11 of the present embodiment has a rectangular opening extending in the left-right direction. The vertical louver 11 is rotatably formed so that the direction of the opening is changed up and down. The vertical louver 11 is attached to the housing 1 via, for example, a shaft 11a extending in the horizontal direction. The vertical louver 11 is formed rotatably around the shaft 11a.

  The wind direction changing unit 10 has a first motor 12 for moving the vertical louver 11. The first motor 12 is provided inside the housing 1. The first motor 12 rotates the vertical louver 11 via the gear 12a, the gear 12b, and the gear 12c. When the vertical louver 11 rotates, the orientation of the opening of the vertical louver 11 is changed to the vertical direction. As a result, the blowing direction is changed to the vertical direction.

  Further, the wind direction changing unit 10 has a left-right louver 13 as an example of a second changing unit that changes the direction in which air is sent from the air outlet 4 to the left-right direction. The left-right louver 13 is formed by a plate-shaped member extending in the vertical direction. As an example, the left-right louver 13 includes six plate-shaped members extending in the vertical direction. The six plate-shaped members extending in the vertical direction are arranged at equal intervals, for example.

  The left-right louver 13 is arranged inside the frame-shaped up-down louver 11. As an example, the left-right louver 13 is attached to the up-down louver 11 via an axis (not shown) extending along the up-down direction. The left-right louver 13 is rotatable about an axis along the up-down direction. In addition, as an example, the vertical louvers 11 and the horizontal louvers 13 are arranged so that the horizontal center of the vertical louvers 11 and the horizontal center of the entire horizontal louvers 13 coincide.

  The wind direction changing unit 10 has a second motor 14 for moving the left and right louvers 13. The second motor 14 is provided inside the housing 1. The wind direction changing unit 10 also has a link 15. The link 15 is connected to the rear part of the left-right louver 13, for example. The link 15 is connected to the second motor 14. The left and right louvers 13 and the second motor 14 are connected via a link 15.

  When the second motor 14 is driven, the link 15 moves. When the link 15 moves, the left-right louver 13 rotates in conjunction with the link 15. As an example, the left-right louver 13 rotates about an axis along the up-down direction that attaches the left-right louver 13 to the up-down louver 11. By rotating the left-right louver 13, the blowing direction is changed to the left-right direction.

  The link 15 is formed so as to interlock with the vertical louver 11. When the vertical louver 11 moves, the link 15 moves together with the vertical louver 11. When the link 15 moves, the left-right louver 13 connected to the link 15 also moves. When the vertical louver 11 moves, the horizontal louver 13 moves together with the link 15 that interlocks with the vertical louver 11. In this way, the horizontal louvers 13 move in the same direction as the vertical louvers 11 move.

  The dehumidifier 100 also includes a sensor unit 16. In the present embodiment, the sensor unit 16 is arranged inside the frame-shaped vertical louver 11. As an example, the sensor unit 16 is arranged at the center position of the vertical louver 11 in the horizontal direction.

  FIG. 6 is a front view of the sensor unit 16 according to the first embodiment. FIG. 7 is a sectional view showing the structure of the sensor unit 16 according to the first embodiment. FIG. 7 shows a cross section of the sensor unit 16 at the CC position in FIG. The front direction of the paper surface of FIG. 6 is the front direction of the sensor unit 16. The vertical direction on the paper surface of FIG. 6 is the vertical direction of the sensor unit 16. In FIG. 7, the right direction on the paper surface is the front direction of the sensor unit 16, and the left direction on the paper surface is the back direction of the sensor unit 16. The up-down direction on the paper surface of FIG. 7 is the up-down direction of the sensor unit 16.

  As shown in FIGS. 6 and 7, the sensor unit 16 has a sensor case 17. The sensor case 17 is a member that serves as an outer frame of the sensor unit 16. As an example, the sensor case 17 is formed in a tubular shape. The sensor case 17 is supported, for example, by a shaft (not shown) extending in the vertical direction. The sensor case 17 is supported, for example, by a shaft (not shown) extending in the left-right direction. The sensor case 17 can rotate around these axes.

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

  The sensor case 17 is provided so that the front surface of the sensor case 17 faces the air blowing direction. As described above, the sensor case 17 is mechanically connected to the link 15 or the left and right louvers 13. The sensor case 17 is interlocked with the left-right louver 13. The sensor case 17 moves in the same direction as the left-right louver 13 moves.

  Further, as described above, the left-right louver 13 moves together with the up-down louver 11. When the vertical louver 11 moves, the sensor case 17 interlocks with the vertical louver 11. The sensor case 17 moves in the same direction as the vertical louver 11 moves. In this way, even when the air blowing direction is changed, the front surface of the sensor case 17 faces the changed air blowing direction.

  The sensor case 17 of the present embodiment has a sensor window 17a. The sensor window 17a is formed in the front part of the sensor case 17, as shown in FIGS. 6 and 7. The sensor window 17a is made of a material having a high infrared transmittance. The material having a high infrared transmittance is, for example, silicon. Here, the region where the air blown out from the air outlet 4 hits is hereinafter referred to as a blower region. The sensor window 17a is arranged and formed so that infrared rays radiated from this air-blowing area are transmitted.

  The sensor section 16 has a surface temperature detecting section 18 as an example of the surface temperature detecting means. The surface temperature detection unit 18 is a device that detects the surface temperature of an object in a non-contact state. In the present embodiment, the surface temperature detecting unit 18 receives the infrared light transmitted through the sensor window 17a, and detects the surface temperature of the target object that emits the infrared light. The surface temperature detecting unit 18 detects the surface temperature of the air blowing area. That is, the surface temperature detection unit 18 detects the surface temperature of the object on which the air sent from the air outlet 4 is hit.

  The structure of the surface temperature detection unit 18 will be described in more detail. The surface temperature detector 18 is provided inside the sensor case 17. The surface temperature detector 18 is arranged on the back side of the sensor window 17a. As an example, the surface temperature detector 18 uses a thermoelectromotive force. The surface temperature detecting unit 18 that detects the surface temperature by using thermoelectromotive force has an infrared absorbing film and a thermistor.

  The infrared absorption film of the surface temperature detection unit 18 absorbs the infrared light transmitted through the sensor window 17a. The infrared absorbing film has a heat sensitive portion. The heat-sensitive portion of the infrared absorbing film heats up by absorbing the infrared rays that have passed through the sensor window 17a. The heat-sensitive part of the infrared absorbing film serves as a hot junction. Further, the thermistor of the surface temperature detecting unit 18 detects the temperature of the part of the infrared absorbing film which is not the heat sensitive part. A portion of the infrared absorbing film that is not a heat sensitive portion becomes a cold junction. The surface temperature detection unit 18 detects the surface temperature of the region that emits infrared rays absorbed by the infrared absorption film from the temperature difference between the hot junction and the cold junction. In this way, the surface temperature detection unit 18 detects the surface temperature of the air blowing area.

  The air blowing area, which is an area where the air sent out from the air outlet 4 hits, is changed together with the air blowing direction. The surface temperature detection unit 18 provided inside the sensor case 17 moves together with the sensor case 17. Further, as described above, the sensor case 17 moves together with the vertical louver 11 and the horizontal louver 13. That is, the surface temperature detector 18 moves together with the vertical louver 11 and the horizontal louver 13. The sensor window 17a formed in the front part of the sensor case 17 also moves together with the vertical louver 11 and the horizontal louver 13. As a result, the surface temperature detecting unit 18 can detect the surface temperature of the changed blast area even when the blast area is changed.

  Further, the sensor unit 16 has an irradiation unit 19 as an example of an irradiation unit that irradiates visible light. The irradiation unit 19 has a light source 19a and a lens 19b. The lens 19b is provided on the front portion of the sensor case 17. As an example, the lens 19b is arranged below the sensor window 17a. The light source 19 a is provided inside the sensor case 17. The light source 19a is provided on the back side of the lens 19b.

  The light source 19a emits visible light. The light source 19a is, for example, an LED. The light source 19a may be a laser diode. In the present embodiment, the light source 19a emits visible light in the front direction. As an example, the light source 19a emits visible light having a luminous intensity of 1000 mcd or more. Further, as an example, the light source 19a emits green visible light. The color of visible light emitted from the light source 19a is not limited to green. The color of visible light emitted by the light source 19a may be orange or the like.

  The lens 19b is for condensing visible light emitted from the light source 19a. The lens 19b is, for example, a plano-convex lens made of acrylic resin. The material of the lens 19b may be, for example, polycarbonate resin or glass. Further, the lens 19b may be a Fresnel lens.

  The portion of the sensor case 17 between the light source 19a and the lens 19b is formed of, for example, a material that transmits visible light emitted by the light source 19a. An opening may be formed in a portion of the sensor case 17 between the light source 19a and the lens 19b. In the present embodiment, visible light emitted from the light source 19a in the front direction reaches the lens 19b.

  Visible light emitted from the light source 19a is condensed by passing through the lens 19b. The visible light condensed by the lens 19b is easily visible. The visible light collected by the lens 19b is emitted to the outside of the sensor case 17 and the housing 1. The light source 19a and the lens 19b are provided so that the visible light condensed by the lens 19b is emitted in the front direction of the sensor case 17.

  As described above, the front surface of the sensor case 17 faces the air blowing direction. The visible light collected by the lens 19b is emitted in the blowing direction. The light source 19a and the lens 19b are provided in the sensor case 17. The light source 19 a and the lens 19 b move together with the sensor case 17. As described above, the sensor case 17 moves together with the vertical louver 11 and the horizontal louver 13. That is, the light source 19 a and the lens 19 b move together with the vertical louver 11 and the horizontal louver 13. Therefore, even when the blowing direction is changed, the visible light condensed by the lens 19b is emitted in the changed blowing direction. The user can confirm the blowing direction by looking at the visible light that is easily visible.

  Here, the area irradiated with the visible light condensed by the lens 19b is referred to as an irradiation area 30. In other words, the irradiation area 30 is an area illuminated by visible light that is in a state where it is easily visible.

  The light source 19a and the lens 19b are arranged and formed so that at least a part of the irradiation area 30 is included in the air blowing area. The user can confirm the air blowing area by looking at the irradiation area 30 illuminated by the visible light. Further, as an example, the light source 19a and the lens 19b may be arranged and formed such that the entire irradiation region 30 is included in the air blowing region. As an example, the light source 19a and the lens 19b are arranged and formed so that the irradiation region 30 at a position 1 m away from the housing 1 is a circle having a diameter of 60 mm. The size and shape of the irradiation area 30 are not limited to those in this embodiment. The shape of the irradiation region 30 may be, for example, a rectangle or the like.

  As described above, the surface temperature detecting unit 18 of the present embodiment detects the surface temperature of the air blowing area. The surface temperature detection unit 18 may detect the surface temperature of the target object included in the irradiation region 30. That is, the surface temperature detection unit 18 may detect the surface temperature of the object illuminated by visible light. For example, the sensor window 17a may be arranged and formed so that infrared rays emitted from the irradiation region 30 are transmitted. As an example, the surface temperature detection unit 18 detects the surface temperature of the entire irradiation region 30.

  In addition, the dehumidifier 100 of this embodiment includes a control device 20 and an operation unit 21. The control device 20 is connected to each device included in the dehumidifier 100.

The setting button 21c is for setting the dehumidifier 100. The setting button 21c transmits to the control device 20 a signal according to the operation by the user.

  The operation key 21d is an example of operation means for transmitting an operation instruction. The operation key 21d is for moving the wind direction changing unit 10. The operation key 21d is, for example, a cross key. The operation key 21d transmits to the control device 20 a signal according to the operation by the user. Hereinafter, the signal transmitted by the operation key 21d to the control device 20 is also referred to as an operation instruction. Upon receiving the operation instruction, the control device 20 operates based on the received operation instruction. The operation keys 21d may be keys other than the cross key.

The surface temperature detection unit 18 converts the detected surface temperature information into an electric signal such as a voltage. The surface temperature detection unit 18 transmits the converted electric signal to the control device 20. The control device 20 controls the fan motor 6, the dehumidifying unit 7, the first motor 12, the second motor 14, and the irradiation unit 19 based on the electric signal from the surface temperature detection unit 18.

  As shown in FIG. 8, the control device 20 of the present embodiment has an operation control unit 20a, a storage unit 20b, a temperature determination unit 20c, a setting unit 20d, and an irradiation control unit 20e.

  The operation control unit 20a controls the first motor 12 and the second motor 14 based on the operation instruction from the operation key 21d. As described above, when the first motor 12 and the second motor 14 move, the blowing direction is changed. The operation control unit 20a of the present embodiment is an example of a wind direction control means for controlling the direction in which air is sent out from the air outlet 4.

  The storage unit 20b is an example of a storage unit. In the storage unit 20b, for example, a plurality of operation modes are set in advance. For example, the operation control unit 20a executes the process of one operation mode from the plurality of operation modes set in the storage unit 20b based on the signal from the mode selection button 21b. 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 based on the signal from the mode selection button 21b.

  As an example, the plurality of operation modes set in the storage unit 20b include the first mode. The first mode is an operation mode in which dry air is concentratedly supplied to a narrow range. When the dehumidifier 100 operates with the first mode selected, the wind direction changing unit 10 is fixed without swinging. Thereby, for example, a small amount of dry air is applied to an object such as a small amount of shoes or a small amount of clothes 31.

  In addition, the plurality of operation modes set in the storage unit 20b include, for example, the second mode. The second mode is a mode for suppressing the occurrence of dew condensation. When the dehumidifier 100 operates in the state in which the second mode is selected, the surface temperature detection unit 18 detects a low temperature place in the room, and the dry air is sent toward the low temperature place. As a result, the temperature of the cold place in the room rises and the room dries. In this way, the occurrence of condensation is suppressed.

  The temperature determination unit 20c makes a determination based on the electric signal transmitted from the surface temperature detection unit 18. The temperature determination unit 20c is an example of a determination unit that makes various determinations. In the present embodiment, storage unit 20b stores information on the reference value of the surface temperature. The temperature determination unit 20c determines the surface temperature based on the temperature information included in the electric signal from the surface temperature detection unit 18 and the reference value information stored in the storage unit 20b.

  Information on the reference value of the surface temperature is stored in the storage unit 20b as a table. FIG. 9 is a diagram schematically showing the information of the reference value of the surface temperature stored in the storage unit 20b of the first embodiment. The storage unit 20b stores information on the first temperature Th1 and the second temperature Th2, which are examples of the reference value of the surface temperature.

  The first temperature Th1 and the second temperature Th2 are reference values for determining whether or not there is a person in the air blowing direction with respect to the housing 1. The first temperature Th1 and the second temperature Th2 are set based on the human body temperature or the skin surface temperature. The first temperature Th1 is, for example, 35 ° C. The second temperature Th2 is, for example, 37 ° C. It should be noted that the first temperature Th1 and the second temperature Th2 may be set as temperatures lower than the body temperature of the person in consideration of clothes or the like worn by the person.

  Here, the temperature range from the first temperature Th1 which is the lower limit value to the second temperature Th2 which is the upper limit value is defined as the first reference Tr1. In the present embodiment, the temperature determination unit 20c determines whether the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1. This determination is a determination as to whether or not there is a person in the blowing direction with respect to the housing 1. The dehumidifier 100 of the present embodiment stops the irradiation of visible light when the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1. The first reference Tr1 is an example of a reference temperature range for determining the presence or absence of a person.

  In addition, the storage unit 20b may store information on the third temperature Th3, which is an example of the reference value of the surface temperature. The third temperature Th3 is set as a temperature for determining whether or not an object such as laundry is dried. The temperature of an object such as laundry containing water becomes lower than the ambient temperature. As an example, the temperature of the dried object becomes equal to or higher than the ambient temperature. The third temperature Th3 is set based on the air temperature, for example. The third temperature Th3 is 20 ° C., for example. Here, the temperature range in which the lower limit value is the third temperature Th3 is the second reference Tr2. As shown in FIG. 9, the first reference Tr1 and the second reference Tr2 may overlap. As an example, the temperature determination unit 20c determines whether the surface temperature detected by the surface temperature detection unit 18 is within the second reference Tr2. This determination is a determination as to whether or not the drying of the object has been completed.

  The setting unit 20d sets the setting direction in the storage unit 20b according to the signal from the setting button 21c. The setting button 21c transmits a signal to the setting unit 20d when pressed when the irradiation unit 19 is emitting visible light. When the setting unit 20d receives the signal from the setting button 21c, the setting unit 20d sets the direction in which the visible light is emitted by the irradiation unit 19 at that time in the storage unit 20b as the setting direction. The setting button 21c and the setting unit 20d in the present embodiment are an example of setting means for setting the setting direction.

  The irradiation control unit 20e controls the irradiation unit 19. In the present embodiment, the irradiation control unit 20e controls the light source 19a of the irradiation unit 19. The irradiation control unit 20e is an example of irradiation control means. The irradiation control unit 20e controls the light source 19a based on the determination result of the temperature determination unit 20c.

  FIG. 10 is a diagram showing an example of the configuration of the control device 20 according to the first embodiment. Each function of the operation control unit 20a, the storage unit 20b, the temperature determination unit 20c, the setting unit 20d, and the irradiation control unit 20e of the control device 20 in the present embodiment is realized by, for example, a processing circuit. The processing circuit may be the dedicated hardware 200. The processing circuit may include a processor 201 and a memory 202. A part of the processing circuit may be formed as dedicated hardware 200, and the processing circuit may further include a processor 201 and a memory 202. In the example shown in FIG. 10, a part of the processing circuit is formed as dedicated hardware 200. Further, in the example illustrated in FIG. 10, the processing circuit further includes a processor 201 and a memory 202 in addition to the dedicated hardware 200.

  A processing circuit, some of which is at least one dedicated hardware 200, may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. .

  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, the setting unit 20d, and the irradiation control unit 20e of the control device 20 are 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 realizes the function of each unit by reading and executing the program stored in the memory 202. The processor 201 is also called a CPU (Central Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. The memory 202 corresponds to, for example, a RAM, a ROM, a flash memory, a nonvolatile or volatile semiconductor memory such as an EPROM and an EEPROM, or a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.

  As described above, the processing circuit uses hardware, software, firmware, or a combination thereof to function the operation control unit 20a, the storage unit 20b, the temperature determination unit 20c, the setting unit 20d, and the irradiation control unit 20e of the control device 20. Can be realized. The configuration of the dehumidifier 100 is not limited to the configuration in which the operation is controlled by the single controller 20. The dehumidifier 100 may be configured so that its operation is controlled by cooperation of a plurality of devices.

  Next, the operation of the dehumidifier 100 of this embodiment will be described. FIG. 11 is a diagram showing the dehumidifier 100 during the operation of the first embodiment. FIG. 12 is a flowchart showing control of the irradiation unit 19 of the first embodiment. Control of the irradiation unit 19 based on the surface temperature detected by the surface temperature detection unit 18 will be described with reference to the flowchart of FIG.

  The dehumidifier 100 is used indoors, such as a living room, for example. The dehumidifier 100 starts operation when the user presses the operation button 21a. The operation button 21a pressed by the user transmits a signal to the operation control unit 20a. When the operation control unit 20a receives the 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. As shown in FIG. 4, the room air P is taken into the housing 1 from the suction port 3 by the blower fan 6a. The indoor air P is dehumidified by the dehumidifying section 7 to become dry air Q. The dry air Q is blown out into the room from the air outlet 4 by the blower fan 6a. As described above, the dehumidifier 100 starts operating (step S101).

  When the operation control unit 20a drives the fan motor 6 and the dehumidifying unit 7, the operation control unit 20a causes the light source 19a of the irradiation unit 19 to emit visible light. Visible light emitted from the light source 19a is condensed by the lens 19b. The visible light condensed by the lens 19b is emitted in the blowing direction of the dry air Q (step S102). The process of step S101 and the process of step S102 described above may be performed simultaneously or in reverse order.

  The blowing direction of the dry air Q depends on the state of the wind direction changing unit 10. The irradiation unit 19 irradiates visible light in the blowing direction. As shown in FIG. 11, the visible light emitted in the blowing direction of the dry air Q illuminates the irradiation area 30. 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 by 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. As a result, the vertical louver 11 and the horizontal louver 13 move. By moving the vertical louvers 11 and the horizontal louvers 13, the blowing direction is changed. When the vertical louver 11 and the horizontal louver 13 move, the sensor unit 16 moves together. The irradiation unit 19 provided in the sensor case 17 of the sensor unit 16 also moves. The irradiation unit 19 moves so as to irradiate visible light in the changed blowing direction. The irradiation area 30 moves in accordance with the change in the blowing direction (step S103).

  The user of the dehumidifier 100 according to the present embodiment can visually recognize the blower area hit by the dry air Q by looking at the irradiation area 30 illuminated by visible light. For example, as shown in FIG. 11, the user operates the operation key 21d while looking at the irradiation region 30 so that the clothes 31 that have been installed in advance are illuminated with visible light. As a result, the dry air Q is intensively applied to the clothes 31. The user of the dehumidifier 100 of the present embodiment can easily recognize the blowing direction of the dry air Q by looking at the irradiation region 30.

  The user can easily change the blowing direction of the dry air Q to any direction by using the operation key 21d. The user can intensively apply the dry air Q to the clothes 31 by moving the irradiation area 30 toward the clothes 31 to be dried. The user can dry the clothes 31 with the dry air Q without moving the clothes 31 that have been previously dried according to the position of the dehumidifier 100. According to the present 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, the surface temperature detection unit 18 of the present embodiment detects the surface temperature of the air blowing area when the dehumidifier 100 is operating. The surface temperature detection unit 18 sends an electric signal including information on the detected surface temperature to the control device 20. The temperature determination unit 20c of the control device 20 determines the surface temperature based on the temperature information included in the electric signal from the surface temperature detection unit 18 and the reference value information stored in the storage unit 20b. As described above, the temperature determination unit 20c of the present embodiment determines whether the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1. This determination is a determination as to whether or not there is a person in the blowing direction with respect to the housing 1 (step S104).

  For example, when there is no person in the blowing direction with respect to the housing 1, the surface temperature detected by the surface temperature detection unit 18 is outside the first reference Tr1. When the temperature determination unit 20c determines that the surface temperature detected by the surface temperature detection unit 18 is outside the first reference Tr1, the processes after step S102 are executed again. When the temperature determination unit 20c determines that the surface temperature detected by the surface temperature detection unit 18 is outside the first reference Tr1, the irradiation control unit 20e causes the light source 19a to continue to emit light. Thereby, the irradiation of visible light by the irradiation unit 19 is continued.

  Further, for example, when there is a person in the air blowing direction with respect to the housing 1, the surface temperature detected by the surface temperature detecting unit 18 is within the first reference Tr1. When the temperature determination unit 20c determines that the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1, the irradiation control unit 20e causes the light source 19a to stop emitting light. As a result, the irradiation of visible light by the irradiation unit 19 is stopped (step S105).

  When the irradiation of the visible light by the irradiation unit 19 is stopped in step S105, the determination in step S104 is performed again. When the surface temperature detected by the surface temperature detection unit 18 is outside the first reference Tr1 while the irradiation of visible light from the irradiation unit 19 is stopped, the irradiation control unit 20e causes the light source 19a to resume light emission. As a result, the irradiation of visible light by the irradiation unit 19 is restarted. After the irradiation of visible light by the irradiation unit 19 is restarted, the determination of step S104 is performed again. When the surface temperature detected by the surface temperature detection unit 18 falls within the first reference Tr1 while the irradiation of the visible light by the irradiation unit 19 is restarted, the process of step S105 is executed again, and the visible light by the irradiation unit 19 is emitted. Irradiation stops.

  Next, the operation of the dehumidifier 100 of the present embodiment in the first mode will be described. FIG. 13 is a flowchart showing the operation of the dehumidifier 100 of the first embodiment in the first mode. Step S201 of FIG. 13 corresponds to step S101 of FIG. The dehumidifier 100 starts the operation when the user operates the operation button 21a (step S201).

  The user may operate the mode selection button 21b after starting the operation of the dehumidifier 100 with the operation button 21a. The user operates the mode selection button 21b to select the operation mode (step S202).

  The operation of the dehumidifier 100 in this first mode will be described below on the assumption that the user has selected the first mode. The operation control unit 20a executes the process of the first mode set in the storage unit 20b based on the signal from the mode selection button 21b. The operation control unit 20a causes the irradiation unit 19 to emit visible light (step S203). This step S203 corresponds to step S102 of FIG.

  In the example shown in FIG. 13, the irradiation unit 19 irradiates visible light when the processing in the first mode is executed. The irradiation unit 19 may start irradiation of visible light at the same time when the operation of the dehumidifier 100 is started. Further, the irradiation unit 19 may start irradiation of visible light at the same time as the setting button 21c is pressed, or after a certain time has elapsed after the setting button 21c was pressed.

  The user operates the operation key 21d to change the blowing direction and the irradiation area 30 (step S204). This step S204 corresponds to step S103 of FIG. Here, the user who has selected the first mode presses the setting button 21c while the clothes 31 are illuminated by visible light, for example. The setting button 21c pressed by the user sends a signal to the setting unit 20d. When the setting unit 20d receives 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 in the storage unit 20b as the setting direction. 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 air blowing direction is fixed in this set direction (step S205).

  When the blowing direction is fixed in the set direction, the dry air Q continues to be blown out in the set direction. The surface temperature detecting unit 18 detects the surface temperature of the clothes 31 on which the dry air Q is hit. The surface temperature detection unit 18 sends an electric signal including information on the detected surface temperature to the control device 20. The temperature determination unit 20c of the control device 20 determines the surface temperature based on the temperature information included in the electric signal from the surface temperature detection unit 18 and the reference value information stored in the storage unit 20b. The temperature determination unit 20c determines whether the surface temperature detected by the surface temperature detection unit 18 is within the second reference Tr2. This determination is a determination of whether or not the drying of the target object is completed (step S206).

  As described above, when the blowing direction is fixed in the set direction, the dry air Q continues to be blown out in the set direction. The temperature determination unit 20c continues the determination in step S206 until the surface temperature of the clothes 31 hit by the dry air Q falls within the second reference Tr2. The dry air Q continues to hit the clothes 31 until the surface temperature of the clothes 31 falls within the second reference Tr2. When the surface temperature detected by the surface temperature detection unit 18 is within the second reference Tr2, the operation control unit 20a stops the fan motor 6, the dehumidifying unit 7, and the irradiation unit 19. As a result, the operation of the dehumidifier 100 ends (step 207).

  The process shown in the flowchart of FIG. 13 is performed in parallel with the process shown in the flowchart of FIG. Even when the first mode is selected, the irradiation unit 19 stops the irradiation of visible light when the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1.

  The user of the dehumidifier 100 of the present embodiment can intensively send the dry air Q in any direction by operating the setting button 21c. The dry air Q is reliably sent to the specific clothes 31 without waste. As a result, wasteful electricity bills due to the air blow to the objects that do not need to be dried are reduced. Further, the dehumidifier 100 of the present embodiment automatically ends the operation when the drying of the object is completed. This further reduces wasteful electricity bills.

  In addition, when the surface temperature detected by the surface temperature detecting unit 18 in the above step S206 falls within the second reference Tr2, the process of step S202 may be performed again. Further, the determination in step S206 may not be performed. For example, the dehumidifier 100 may end the operation after a certain period of time in which the process of step S205 has been performed.

  Next, the operation of the dehumidifier 100 of the present embodiment in the second mode will be described. FIG. 13 is a flowchart showing the operation of the dehumidifier 100 of the first embodiment in the second mode. Step S301 of FIG. 14 corresponds to step S201 of FIG. Step S302 in FIG. 14 corresponds to step S202 in FIG. The description of step S301 and step S302 is omitted.

  Hereinafter, assuming that the user has selected the second mode in step S302, the operation of the dehumidifier 100 in this second mode will be described. The operation control unit 20a executes the process of the second mode set in the storage unit 20b based on the signal from the mode selection button 21b. The operation control unit 20a causes the irradiation unit 19 to emit visible light (step 303). This step S303 corresponds to step S203 of FIG. The user operates the operation key 21d to change the blowing direction and the irradiation area 30 (step S304). This step S304 corresponds to step S204 of FIG.

  When the processing in the second mode is being executed, the surface temperature detecting unit 18 detects the surface temperature not only in the air-blowing region but also in a range that the surface temperature detecting unit 18 can detect. The operation control unit 20a controls the first motor 12 and the second motor 14 so that the dry air Q hits a low temperature place in the room based on the surface temperature detected by the surface temperature detection unit 18 (step S305). ). The low temperature place is, for example, a place where the surface temperature is equal to or lower than a preset threshold value. This threshold is set in the storage unit 20b.

  The surface temperature detection unit 18 detects the surface temperature of a low temperature place where the dry air Q is hit. The surface temperature detection unit 18 sends an electric signal including information on the detected surface temperature to the control device 20. The temperature determination unit 20c of the control device 20 determines the surface temperature based on the temperature information included in the electric signal from the surface temperature detection unit 18 and the reference value information stored in the storage unit 20b. The temperature determination unit 20c determines whether the surface temperature detected by the surface temperature detection unit 18 is within the second reference Tr2. This determination is a determination as to whether or not the temperature of the low-temperature place on which the dry air Q hits is about the same as the ambient temperature (step S306).

Temperature determination unit 20c, the surface temperature of the location where the dry air Q is hit by until the second reference in Tr2, continues the determination of step S306. When the surface temperature detected by the surface temperature detection unit 18 is within the second reference Tr2, the operation control unit 20a stops the fan motor 6, the dehumidifying unit 7, and the irradiation unit 19. As a result, the operation of the dehumidifier 100 ends (step 307). As a result, there is no part of the room where the temperature is low, and the occurrence of dew condensation is suppressed.

  In addition, when the surface temperature detected by the surface temperature detection unit 18 in the above step S307 falls within the second reference Tr2, the process of step S305 may be performed again. When the second mode is selected, the dehumidifier 100 may operate so that all of the cold places in the room are eliminated.

  The process shown in the flowchart of FIG. 14 is performed in parallel with the process shown in the flowchart of FIG. Even when the second mode is selected, the irradiation unit 19 stops the irradiation of visible light when the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1.

  The dehumidifier 100 of the above-mentioned embodiment stops irradiation of visible light when a person is present in the air blowing direction with respect to the housing 1. As a result, the visible light emitted from the irradiation unit 19 does not directly enter the eyes of the user. According to the above embodiment, the dehumidifier 100 that is more convenient for the user can be obtained.

  The surface temperature detection unit 18 and the temperature determination unit 20c in the above embodiment are examples of a person detection unit that detects a person. The dehumidifier 100 may include, for example, a sensor using a pyroelectric element as a person detecting unit. Further, the dehumidifier 100 may include a sensor for detecting a person by ultrasonic waves or a sensor for detecting a person by visible light as a person detecting means. The dehumidifier 100 may include a plurality of types of sensors that detect a person. In addition, the dehumidifier 100 may include a plurality of specific types of sensors that detect a person. Since the person detecting means is composed of a plurality of sensors, it is possible to detect a person with high accuracy without being affected by the environment such as temperature. Further, at least one of the plurality of sensors for detecting a person may be provided on the right side surface of the housing 1, for example. Further, at least one of the plurality of sensors for detecting a person may be provided on the left side surface of the housing 1, for example. By arranging a plurality of sensors for detecting a person in a dispersed manner, the range in which the presence of a person can be detected by the plurality of sensors becomes wider.

In the above embodiment, the presence or absence of a person is determined based on the surface temperature detected by the surface temperature detection unit 18. As a result, the presence or absence of a person is accurately determined. Further, the surface temperature detection unit 18 for detecting a person can determine whether the drying of the object such as the clothes 31 is completed. According to the above-described embodiment, the dehumidifier 100 with better usability can be obtained without adding unnecessary components. Further, in the above-described embodiment, the presence or absence of a person is determined based on the first reference Tr1 which is an example of the reference temperature range. As a result, the presence / absence of a person is more accurately determined.

  In addition, for example, the information of the second temperature Th2 may not be set in the storage unit 20b. The upper limit value of the first reference Tr1 may not be set. The temperature determination unit 20c may determine, for example, whether the surface temperature detected by the surface temperature detection unit 18 is equal to or higher than the first temperature Th1. This determination is a determination as to whether or not there is a person in the blowing direction with respect to the housing 1. For example, when there is no person in the air blowing direction with respect to the housing 1, the surface temperature detected by the surface temperature detection unit 18 becomes lower than the first temperature Th1. Further, for example, when there is a person in the air blowing direction with respect to the housing 1, the surface temperature detected by the surface temperature detecting unit 18 becomes the first temperature Th1 or more. As described above, the information about one of the first temperature Th1 and the second temperature Th2 may not be set in the storage unit 20b.

  Further, the reference values of the first temperature Th1, the second temperature Th2, the third temperature Th3, etc. may not be set as fixed values. The reference values of the first temperature Th1, the second temperature Th2, the third temperature Th3, and the like may be calculated by the control device 20 based on the room air temperature and the like, for example. The dehumidifier 100 may include a sensor or the like for measuring the indoor temperature. The indoor air temperature may be measured by the surface temperature detection unit 18.

  In the above embodiment, the irradiation unit 19 is provided in the sensor case 17 together with the surface temperature detection unit 18. The irradiation unit 19 may be provided at a place apart from the surface temperature detection unit 18. Further, the dehumidifier 100 may be configured such that the irradiation unit 19 and the wind direction changing unit 10 can operate independently. The dehumidifier 100 may include, in addition to the first motor 12 and the second motor 14 for moving the wind direction changing unit 10, components for moving the irradiation unit 19 independently of the wind direction changing unit 10. . Further, the control device 20 may move the irradiation unit 19 provided at a position away from the wind direction changing unit 10 in accordance with the movement of the wind direction changing unit 10.

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

  In the above-described 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 a simple operation of operating the operation key 21d on the housing 1. The dehumidifier 100 may include a remote controller having operation keys 21d instead of the operation unit 21. This allows the user to operate the dehumidifier 100 at a position away from the housing 1. Further, the dehumidifier 100 may include both the operation unit 21 and the remote controller.

  Although the operation of drying the clothes 31 is described as an example in the above embodiment, the target to which the dry air Q is blown is not limited to the clothes 31. The dehumidifier 100 can also be used to dry indoor wet areas such as bathroom walls and floors.

Embodiment 2.
Next, a second embodiment will be described. The configuration of the dehumidifier 100 of the second embodiment is shown in FIGS. 1 to 10 as in the first embodiment. Descriptions of the same configurations and operations as those in the first embodiment will be omitted.

  FIG. 15 is a flowchart showing control of the irradiation unit 19 of the second embodiment. Steps S401 to S404 in the flowchart of FIG. 15 are the same as steps S101 to S104 in the flowchart of FIG. 12 of the first embodiment. The description of steps S401 to S404 will be omitted.

  In step S404, similarly to step S104 of the first embodiment, it is determined whether or not there is a person in the air blowing direction with respect to the housing 1. In step S404, the temperature determination unit 20c determines whether the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1.

  For example, when there is no person in the blowing direction with respect to the housing 1, the surface temperature detected by the surface temperature detection unit 18 is outside the first reference Tr1. When the temperature determination unit 20c determines that the surface temperature detected by the surface temperature detection unit 18 is outside the first reference Tr1, the processes after step 402 are executed again. When the temperature determination unit 20c determines that the surface temperature detected by the surface temperature detection unit 18 is outside the first reference Tr1, the irradiation control unit 20e causes the light source 19a to continue to emit light. Thereby, the irradiation of visible light by the irradiation unit 19 is continued.

  Further, for example, when there is a person in the air blowing direction with respect to the housing 1, the surface temperature detected by the surface temperature detecting unit 18 is within the first reference Tr1. When the temperature determination unit 20c determines that the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1, the irradiation control unit 20e causes the light source 19a to reduce the luminous intensity of the visible light emitted. As a result, the luminous intensity of the visible light emitted by the irradiation unit 19 decreases (step S405). In this embodiment, strong visible light is not emitted toward the user. For example, the glare when the user looks at the front of the irradiation unit 19 is reduced. Also, the amount of visible light that enters the human eye is reduced. According to the present embodiment, the dehumidifier 100 with good usability can be obtained as in the first embodiment. The process of the flowchart shown in FIG. 15 of the present embodiment may be executed in parallel with the process of the first mode or the process of the second mode, as in the first embodiment.

Embodiment 3.
Next, a third embodiment will be described. The basic configuration of the dehumidifier 101 of the third embodiment is similar to that of the dehumidifier 100 of the first and second embodiments. With respect to the dehumidifier 101, the description of the same configuration and operation as those of the dehumidifier 100 of the first and second embodiments will be omitted.

  FIG. 16 is a perspective view of the dehumidifier 101 of the third embodiment. Further, FIG. 17 is a block diagram showing the functions of the control device 23 of the third embodiment. The dehumidifier 101 of the present embodiment includes a buzzer 22 which is an example of a sounding device. The buzzer 22 is provided on the upper surface of the housing 1, for example. The arrangement of the buzzer 22 is not limited to this embodiment. Further, the buzzer 22 which is an example of the sounding device is electrically connected to the control device 23 of the dehumidifier 101 as shown in FIG. The buzzer 22 is controlled by the operation control unit 20a of the control device 23, for example. The function of the control device 23 of the present embodiment is realized by a processing circuit, similarly to the control device 20 of the first embodiment.

  FIG. 18 is a flowchart showing control of the irradiation unit of the third embodiment. Steps S501 to S505 in the flowchart of FIG. 18 are the same as steps S101 to S105 in the flowchart of FIG. 12 of the first embodiment. The description of steps S501 to S505 will be omitted.

  In the present embodiment, when the irradiation of visible light by the irradiation unit 19 is stopped in step S505, the buzzer 22 makes a sound. The buzzer 22 is operated by the control device 23 electrically connected to the buzzer 22. The dehumidifier 101 can notify the user of the possibility that the user may directly look at the visible light with the buzzer 22 included in the dehumidifier 101. According to the present embodiment, there is less possibility that the user directly looks at strong visible light. According to this embodiment, the dehumidifier 101 that is more convenient for the user can be obtained. The sounding device provided in the dehumidifier 101 is not limited to the buzzer 22 as long as it can emit a sound.

  The dehumidifier according to the present invention is used, for example, to dry an arbitrary object.
