FIG. 5 schematically shows a part of a cross section of the dehumidifier 100 at the BB position in FIG. The vertical and horizontal directions on the paper surface in FIG. 5 correspond to the vertical and horizontal 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. The direction in which air is sent out from the blower outlet 4 is hereinafter referred to as the blowing direction. The air blowing direction is changed by the movement of the wind direction changing unit 10. The air blowing direction is determined by the state of the wind direction changing unit 10. The wind direction changing unit 10 according to the present embodiment is an example of a wind direction determining unit. The wind direction changing unit 10 is disposed in the vicinity of the air outlet 4.

The wind direction change part 10 has the up-down direction louver 11 as an example of the 1st change part which changes the direction in which air is sent from the blower outlet 4 to an up-down direction. The vertical louver 11 is formed according to the shape of the air outlet 4. The vertical 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 three plate-like members extending in the left-right direction as shown in FIG. The vertical louver 11 of the present embodiment has a rectangular opening extending in the left-right direction. The vertical louver 11 is formed to be rotatable 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 to be rotatable about 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 opening direction of the vertical louver 11 is changed to the vertical direction. Thereby, a ventilation direction is changed to an up-down direction.

Moreover, the wind direction change part 10 has the left-right direction louver 13 as an example of the 2nd change part which changes the direction in which air is sent from the blower outlet 4 to the left-right direction. The left-right direction louver 13 is formed by a plate-like member extending in the up-down direction. As an example, the left-right louver 13 includes six plate-like members extending in the up-down direction. The six plate-like members extending in the vertical direction are arranged at equal intervals, for example.

The left-right direction louver 13 is disposed inside the frame-like vertical direction louver 11. As an example, the left-right direction louver 13 is attached to the up-down direction louver 11 via an axis (not shown) along the up-down direction. The left-right direction louver 13 is rotatable about an axis along the vertical direction. As an example, the vertical louver 11 and the horizontal louver 13 are arranged such that the horizontal center of the vertical louver 11 coincides with the horizontal center of the entire horizontal louver 13.

The wind direction changing unit 10 has a second motor 14 for moving the left-right direction louver 13. The second motor 14 is provided inside the housing 1. Further, the wind direction changing unit 10 has a link 15. This link 15 is connected to the rear part of the left-right direction louver 13, for example. The link 15 is connected to the second motor 14. The left-right direction louver 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 vertical direction in which the left-right louver 13 is attached to the vertical louver 11. As the left-right louver 13 rotates, the blowing direction is changed to the left-right direction.

Further, the link 15 is formed so as to be interlocked 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 up-down direction louver 11 moves, the left-right direction louver 13 moves together with the link 15 interlocked with the up-down direction louver 11. In this way, the horizontal louver 13 moves in the same direction as the vertical louver 11 moves.

In addition, the dehumidifier 100 includes a sensor unit 16. In the present embodiment, the sensor unit 16 is disposed inside the frame-like vertical louver 11. As an example, the sensor unit 16 is disposed at a central position in the left-right direction of the up-down direction louver 11.

FIG. 6 is a front view of the sensor unit 16 according to the first embodiment. FIG. 7 is a cross-sectional view illustrating 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 side of the paper surface of FIG. 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 surface direction of the sensor unit 16. The vertical direction on the paper surface of FIG. 7 is the vertical 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 cylindrical shape. For example, the sensor case 17 is supported by a shaft (not shown) extending in the vertical direction. The sensor case 17 is supported by, for example, 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 in the left-right direction of the vertical louver 11. The sensor case 17 is connected to the left-right louver 13 via the link 15. The sensor case 17 may be provided directly on the left-right louver 13 without using the link 15.

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

Also, 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 is interlocked with the vertical louver 11. The sensor case 17 moves in the same direction as the vertical louver 11 moves. In this way, the front surface of the sensor case 17 faces the changed air blowing direction even when the air blowing direction is changed.

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. The sensor window 17a is formed of a material having a high infrared transmittance. A material having a high infrared transmittance is, for example, silicon. Here, the area where the air sent out from the outlet 4 will be referred to as a blowing area hereinafter. The sensor window 17a is arranged and formed so that infrared rays radiated from the air blowing region are transmitted.

The sensor unit 16 includes a surface temperature detection unit 18 as an example of a surface temperature detection unit. The surface temperature detection unit 18 is a device that detects the surface temperature of an object in a non-contact state. In this Embodiment, the surface temperature detection part 18 detects the surface temperature of the target object which emitted the said infrared rays by receiving the infrared rays which permeate | transmitted the sensor window 17a. The surface temperature detection 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 that is hit by the air sent out from the air outlet 4.

The configuration of the surface temperature detector 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 disposed on the back side of the sensor window 17a. As an example, the surface temperature detector 18 uses a thermoelectromotive force. The surface temperature detection unit 18 that detects the surface temperature using the thermoelectromotive force has an infrared absorption film and a thermistor.

The infrared absorption film of the surface temperature detection unit 18 absorbs infrared rays transmitted through the sensor window 17a. The infrared absorbing film has a heat sensitive part. The heat-sensitive portion of the infrared absorbing film is heated by absorbing infrared rays that have passed through the sensor window 17a. The heat sensitive part of the infrared absorbing film becomes a hot junction. The thermistor of the surface temperature detector 18 detects the temperature of a portion that is not a heat sensitive portion of the infrared absorption film. The portion that is not the heat-sensitive portion of the infrared absorbing film becomes a cold junction. The surface temperature detection part 18 detects the surface temperature of the area | region which emitted the infrared rays absorbed by the infrared rays absorption film from the temperature difference of said warm junction and cold junction. Thus, the surface temperature detection part 18 detects the surface temperature of a ventilation area | region.

The air blowing area, which is the area where the air sent out from the air outlet 4 hits, is changed together with the air blowing direction. The surface temperature detector 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. Further, the sensor window 17 a formed in the front portion of the sensor case 17 also moves together with the vertical louver 11 and the horizontal louver 13. Thereby, even when the ventilation area | region is changed, the surface temperature detection part 18 can detect the surface temperature of the ventilation area | region after a change.

In addition, the sensor unit 16 includes an irradiation unit 19 as an example of an irradiation unit that emits visible light. The irradiation unit 19 includes a light source 19a and a lens 19b. The lens 19 b is provided on the front portion of the sensor case 17. As an example, the lens 19b is disposed 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. 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 from 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 a plano-convex lens made of, for example, an acrylic resin. The material of the lens 19b may be, for example, polycarbonate resin or glass. 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 a material that transmits visible light emitted from the light source 19a, for example. Note that an opening may be formed in the sensor case 17 between the light source 19a and the lens 19b. In the present embodiment, the 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 collected by the lens 19b is easily visible. Visible light collected by the lens 19 b is irradiated toward the outside of the sensor case 17 and the housing 1. The light source 19 a and the lens 19 b are provided so that visible light collected by the lens 19 b is irradiated in the front direction of the sensor case 17.

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

Here, an area to which the visible light condensed by the lens 19b is irradiated is referred to as an irradiation area 30. In other words, the irradiation area 30 is an area illuminated by visible light that is easily visible.

The light source 19a and the lens 19b are arranged and formed so that at least a part of the irradiation region 30 is included in the blowing region. The user can check the blowing area by looking at the irradiation area 30 illuminated by the visible light. As an example, the light source 19a and the lens 19b may be arranged and formed so that the entire irradiation region 30 is included in the 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 region 30 are not limited to the present embodiment. The shape of the irradiation region 30 may be, for example, a rectangle.

As described above, the surface temperature detection 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 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 detector 18 detects the surface temperature of the entire irradiation region 30.

In addition, the dehumidifier 100 according to the present embodiment includes a control device 20 and an 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 operation unit 21 is for the user to operate the dehumidifier 100. The operation unit 21 is provided on the rear surface side of the upper surface of the housing 1, for example. As an example, the operation unit 21 includes an operation button 21a, a mode selection button 21b, a setting button 21c, and an operation key 21d.

The operation button 21a is for starting and stopping the operation of the dehumidifier 100. The mode selection button 21b is for selecting an operation mode of the dehumidifier 100. The control device 20 and the operation unit 21 are electrically connected. The operation button 21 a and the mode selection button 21 b of the operation unit 21 transmit a signal corresponding to the operation from the user to the control device 20. The setting button 21c is for setting the dehumidifier 100. The setting button 21 c transmits a signal corresponding to the operation from the user to the control device 20.

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

The operation unit 21 transmits a signal corresponding to the operation from the user to the control device 20. When receiving the signal from the operation unit 21, 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 received signal.

Further, the control device 20 is electrically connected to the surface temperature detection unit 18 as shown in FIG. The surface temperature detector 18 converts the detected surface temperature information into an electrical signal such as a voltage. The surface temperature detection unit 18 transmits the converted electrical 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 electrical signal from the surface temperature detection unit 18.

As shown in FIG. 8, the control device 20 of the present embodiment includes 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 an 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 part 20a of this Embodiment is an example of the wind direction control means for controlling the direction in which air is sent out from the blower outlet 4. FIG.

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 processing for one operation mode from among a plurality of operation modes set in the storage unit 20b based on a 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 a signal from the mode selection button 21b.

As an example, the first mode is included in the plurality of operation modes set in the storage unit 20b. The first mode is an operation mode in which dry air is intensively supplied in a narrow range. When the dehumidifier 100 operates in a state where the first mode is selected, the wind direction changing unit 10 is fixed without swinging. Thereby, for example, a concentrated 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 includes the second mode as an example. The second mode is a mode for suppressing the occurrence of condensation. When the dehumidifier 100 operates in a state where the second mode is selected, the surface temperature detection unit 18 detects a low temperature place in the room, and dry air is sent toward the low temperature place. Thereby, the temperature of the indoor low temperature place rises and it dries. In this way, the occurrence of condensation is suppressed.

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

The information on the reference value of the surface temperature is stored as a table in the storage unit 20b. FIG. 9 is a diagram schematically showing information on 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 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 35 ° C., for example. The second temperature Th2 is 37 ° C., for example. Note 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 worn by the person.

Here, a temperature range from the first temperature Th1 that is the lower limit value to the second temperature Th2 that is the upper limit value is defined as a 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 air blowing direction with respect to the housing 1. The dehumidifier 100 according to the present embodiment stops the irradiation of visible light when the surface temperature detected by the surface temperature detector 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.

Further, information on the third temperature Th3, which is an example of a reference value of the surface temperature, may be stored in the storage unit 20b. The third temperature Th3 is set as a temperature for determining whether an object such as laundry is dried. The temperature of an object such as laundry containing moisture is lower than the ambient temperature. As an example, the temperature of the object that has been dried is equal to or higher than the ambient temperature. The third temperature Th3 is set based on the temperature as an example. The third temperature Th3 is, for example, 20 ° C. Here, a temperature range in which the third temperature Th3 is a lower limit is defined as a 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 a setting direction in the storage unit 20b according to a signal from the setting button 21c. The setting button 21c transmits a signal to the setting unit 20d when pressed when the visible light is irradiated by the irradiation unit 19. When the setting unit 20d receives a signal from the setting button 21c, the setting unit 20d sets, in the storage unit 20b, a direction in which visible light is irradiated by the irradiation unit 19 at that time as a setting direction. The setting button 21c and the setting unit 20d in the present embodiment are an example of setting means for setting a 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 an irradiation control unit. 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 illustrating 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 a processing circuit, for example. The processing circuit may be 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. 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.

The processing circuit, part of which is at least one dedicated hardware 200, includes, 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, 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 is software. , Firmware, or a combination of software and firmware.

Software and firmware are described as programs and stored in the memory 202. The processor 201 reads out and executes the program stored in the memory 202, thereby realizing the function of each unit. The processor 201 is also referred to as 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 nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM and an EEPROM, or a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, and a DVD.

As described above, the processing circuit has 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 by hardware, software, firmware, or a combination thereof. Can be realized. The configuration of the dehumidifier 100 is not limited to a configuration in which the operation is controlled by the single control device 20. The dehumidifier 100 may be configured such that 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 illustrating the dehumidifier 100 during the operation of the first embodiment. FIG. 12 is a flowchart illustrating control of the irradiation unit 19 according to the first embodiment. With reference to the flowchart of FIG. 12, control of the irradiation part 19 based on the surface temperature detected by the surface temperature detection part 18 is demonstrated.

The dehumidifier 100 is used in a room such as a living room. 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 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 current. As shown in FIG. 4, the indoor air P is taken into the housing 1 from the suction port 3 by the blower fan 6 a. The room air P is dehumidified by the dehumidifying unit 7 to become dry air Q. The dry air Q is sent out from the blower outlet 4 into the room by the blower fan 6a. As described above, the dehumidifier 100 starts operation (step S101).

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

The blowing direction of the dry air Q is determined by the state of the wind direction changing unit 10. The irradiation part 19 irradiates visible light toward this ventilation direction. As shown in FIG. 11, the visible light irradiated in the blowing direction of the dry air Q illuminates the irradiation region 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 from the user to the operation control unit 20a.

The operation control unit 20a controls the first motor 12 and the second motor 14 based on the received operation instruction. Thereby, the up-down direction louver 11 and the left-right direction louver 13 move. The air blowing direction is changed by moving the vertical louver 11 and the horizontal louver 13. When the vertical louver 11 and the horizontal louver 13 move, the sensor unit 16 also moves. The irradiation unit 19 provided in the sensor case 17 of the sensor unit 16 also moves together. The irradiation unit 19 moves so as to irradiate visible light in the changed air blowing direction. The irradiation area 30 moves according to the change in the blowing direction (step S103).

The user of the dehumidifier 100 according to the present embodiment can visually recognize the blow area where the dry air Q hits by looking at the irradiation area 30 illuminated with visible light. The user operates the operation key 21d while looking at the irradiation area 30 so that the clothes 31 that have been set in advance are illuminated with visible light, for example, as shown in FIG. Thereby, the dry air Q hits the clothes 31 intensively. 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 an arbitrary direction by the operation key 21d. The user can concentrate the dry air Q on the clothes 31 by moving the irradiation region 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 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 more 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 electrical 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 air 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, irradiation of visible light by the irradiation part 19 continues.

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 detection unit 18 is within the first reference Tr 1. 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. Thereby, irradiation of visible light by the irradiation part 19 stops (step S105).

When the irradiation of visible light by the irradiation unit 19 is stopped in step S105, the determination in step S104 is performed again. If 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. Thereby, irradiation of visible light by the irradiation unit 19 is resumed. After the irradiation of the visible light by the irradiation unit 19 is resumed, the determination in step S104 is performed again. When the surface temperature detected by the surface temperature detection unit 18 is within the first reference Tr1 while the irradiation of the visible light by the irradiation unit 19 is resumed, the process of step S105 is executed again, and the visible light by the irradiation unit 19 is displayed. Irradiation stops.

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

Hereinafter, the operation of the dehumidifier 100 in the first mode will be described 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 in FIG.

In the example shown in FIG. 13, the irradiation unit 19 emits visible light when the first mode process is executed. In addition, the irradiation part 19 may start irradiation of visible light simultaneously with the driving | operation of the dehumidifier 100 being started. Further, the irradiation unit 19 may start the irradiation of visible light at the same time when the setting button 21c is pressed or after a certain time has elapsed since the setting button 21c is pressed.

The user operates the operation key 21d to change the blowing direction and the irradiation region 30 (step S204). This step S204 corresponds to step S103 in FIG. Here, the user who has selected the first mode presses the setting button 21c in a state where the clothes 31 are illuminated by visible light, for example. The setting button 21c pressed by the user transmits a signal to the setting unit 20d. When receiving the signal from the setting button 21c, the setting unit 20d sets the direction in which the visible light is irradiated by the irradiation unit 19 as the setting direction in the storage unit 20b. When the setting direction is set in the storage unit 20b, the operation control unit 20a controls the first motor 12 and the second motor 14 so that the blowing direction is fixed in the setting direction (step S205).

When the blowing direction is fixed in the setting direction, the dry air Q continues to be blown out in the setting direction. The surface temperature detection unit 18 detects the surface temperature of the garment 31 that is struck by the dry air Q. 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 electrical 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 drying of the object has been completed (step S206).

As described above, when the blowing direction is fixed in the setting direction, the dry air Q continues to be blown out in the setting direction. The temperature determination unit 20c continues the determination in step S206 until the surface temperature of the garment 31 that is exposed to 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 falls within the second reference Tr2, the operation control unit 20a stops the fan motor 6, the dehumidifying unit 7, and the irradiation unit 19. Thereby, the operation of the dehumidifier 100 is completed (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 concentrate the dry air Q in an arbitrary direction by operating the setting button 21c. The dry air Q is reliably sent toward the specific clothes 31 without waste. Thereby, the useless electricity bill by the ventilation to the thing which does not need to be dried is reduced. Moreover, the dehumidifier 100 of this Embodiment will complete | finish operation | movement automatically, when drying of a target object is completed. Thereby, useless electricity bill is further reduced.

In addition, when the surface temperature detected by the surface temperature detection part 18 in said step S206 becomes in 2nd reference | standard 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 lapse of a certain time after the process of step S205 is performed.

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

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

When the processing in the second mode is being performed, the surface temperature detection unit 18 detects a surface temperature in a range that can be detected by the surface temperature detection unit 18 as well as the air blowing region. Based on the surface temperature detected by the surface temperature detector 18, the operation controller 20a controls the first motor 12 and the second motor 14 so that the dry air Q hits a cold place in the room (step S305). ). A low-temperature place is a place where the surface temperature is not more than a preset threshold value, for example. 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 electrical 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 where the dry air Q is hit has reached the same level as the surroundings (step S306).

The temperature determination unit 20c continues the determination in step S306 until the surface temperature of the place where the dry air Q is hit falls within the second reference Tr2. When the surface temperature detected by the surface temperature detection unit 18 falls within the second reference Tr2, the operation control unit 20a stops the fan motor 6, the dehumidifying unit 7, and the irradiation unit 19. Thereby, the operation of the dehumidifier 100 is completed (step 307). Thereby, the part which was the indoor low temperature disappears, and generation | occurrence | production of dew condensation is suppressed.

In addition, when the surface temperature detected by the surface temperature detection part 18 in said step S307 becomes in 2nd reference | standard 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 plurality of low-temperature places in the room disappear.

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 embodiment stops the irradiation of visible light when there is a person in the air blowing direction with respect to the housing 1. Thereby, the visible light irradiated from the irradiation part 19 does not enter into a user's eyes directly. According to the above embodiment, the dehumidifier 100 that is more convenient for the user can be obtained.

In addition, the surface temperature detection unit 18 and the temperature determination unit 20c in the above embodiment are an example of a person detection unit that detects a person. The dehumidifier 100 may include, for example, a sensor using a pyroelectric element as a human detection unit. Moreover, the dehumidifier 100 may be provided with a sensor for detecting a person using ultrasonic waves or a sensor for detecting a person using visible light as a person detecting unit. The dehumidifier 100 may include a plurality of types of sensors that detect people. The dehumidifier 100 may include a plurality of specific types of sensors that detect people. The person detection means is configured by a plurality of sensors, and can detect a person with high accuracy without being affected by an environment such as temperature. In addition, at least one of the plurality of sensors that detect a person may be provided on the right side surface of the housing 1, for example. In addition, at least one of the plurality of sensors that detect a person may be provided on the left side surface of the housing 1, for example. A plurality of sensors for detecting a person are arranged in a distributed manner, so that 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 / absence of a person is determined based on the surface temperature detected by the surface temperature detector 18. Thereby, the presence or absence of a person is accurately determined. In addition, the surface temperature detection unit 18 for detecting a person can determine whether an object such as the clothing 31 is completed. If it is said embodiment, the dehumidifier 100 which is more convenient is obtained, without adding a useless component. In the above embodiment, the presence / absence of a person is determined based on a first reference Tr1 that is an example of a reference temperature range. Thereby, the presence or absence of a person is determined with higher accuracy.

In the storage unit 20b, for example, information on the second temperature Th2 may not be set. The upper limit value of the first reference Tr1 may not be set. For example, the temperature determination unit 20c may determine 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 air blowing direction with respect to the housing 1. 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 less 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 detection unit 18 is equal to or higher than the first temperature Th1. Thus, information of one of the first temperature Th1 and the second temperature Th2 may not be set in the storage unit 20b.

Further, the reference values such as the first temperature Th1, the second temperature Th2, and the third temperature Th3 may not be set as fixed values. Reference values such as the first temperature Th1, the second temperature Th2, and the third temperature Th3 may be calculated by the control device 20 based on, for example, the indoor air temperature. The dehumidifier 100 may include a sensor for measuring the room temperature. The indoor air temperature may be measured by the surface temperature detector 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 location away from the surface temperature detection unit 18. Further, the dehumidifier 100 may have a configuration in which the irradiation unit 19 and the wind direction changing unit 10 can operate independently. The dehumidifier 100 may include components for moving the irradiation unit 19 independently of the wind direction changing unit 10 in addition to the first motor 12 and the second motor 14 for moving 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 that is an example of the wind direction determining unit may not include the vertical louver 11 and the horizontal louver 13. The wind direction changing unit 10 may have a nozzle-like structure that can move in the vertical and horizontal directions, for example, in addition to the above-described embodiment.

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

In the above embodiment, the operation of drying the garment 31 is shown as an example. However, the object to which the dry air Q is blown out is not limited to the garment 31. The dehumidifier 100 can also be used when drying indoor wet places such as bathroom walls and floors.

Embodiment 2. FIG.
Next, a second embodiment will be described. The configuration of the dehumidifier 100 according to the second embodiment is shown in FIGS. 1 to 10 as in the first embodiment. The description of the same configuration and operation as in the first embodiment is omitted.

FIG. 15 is a flowchart showing control of the irradiation unit 19 according to 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 from step S401 to step S404 is omitted.

In step S404, as in step S104 of the first embodiment, it is determined whether or not there is a person in the 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 air 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, irradiation of visible light by the irradiation part 19 continues.

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 detection unit 18 is within the first reference Tr 1. 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 emitted visible light. Thereby, the luminous intensity of the visible light irradiated by the irradiation part 19 falls (step S405). If it is this Embodiment, strong visible light will not be irradiated toward a 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 that is easy to use is 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 first mode process or the second mode process, as in the first embodiment.
