There are some (see, for example, Patent Document 1).
JP 2004-28481 A

  Such a conventional dehumidifier needs a sensible heat exchanger for recovering the moisture absorbed by the dehumidification rotor. For this reason, there was a problem that the apparatus was increased in size.

  In addition, it is necessary to form a circulation passage in which the heater, the regeneration unit of the dehumidification rotor, and one passage of the sensible heat exchanger are connected in an annular shape. For this reason, there has been a problem that the apparatus configuration becomes complicated and expensive.

  In addition, since there is no means for increasing the enthalpy of air supplied to the radiator, there is a problem that the operating pressure of the heat pump is lowered in a low temperature environment, the heat absorption capacity is lowered, and the dehumidification amount is reduced. .

  In addition, since there is no means for increasing the enthalpy of the air supplied to the heat absorber, there is a problem that the enthalpy difference between the heat absorber and the supply air is reduced and the dehumidification amount is reduced in a low temperature environment.

  The present invention solves the above-mentioned conventional problems, realizes a dehumidifying operation with a heat pump and a dehumidifying rotor with a small and simple configuration, ensures a dehumidifying amount even in a low temperature environment, and performs an efficient dehumidifying operation throughout the year. The aim is to provide a dehumidifier to obtain.

  In order to achieve the above-described object, the first problem-solving means taken by the present invention is to supply a heat absorber (10) into a main body (1) having an inlet (2) and an outlet (4). The heat pump (13) that absorbs heat from the air and dissipates heat to the supply air in the radiator (12), absorbs moisture from the supply air in the moisture absorption section (26), and is heated in the regeneration section (27) to release moisture. The dehumidifying rotor (22) to be regenerated, the heater (23) for heating the air to be supplied to the regenerating unit (27) and the regenerating unit (27), and the radiator ( 12) to the first supply path (16) to be supplied to the outlet (4) and discharged from the outlet (4), and air is sucked from the inlet (2) and supplied to the heat absorber (10) to be supplied to the outlet (4). ) From the second supply path (17) In the dehumidification rotor (22), at least a part of the air supplied to the radiator (12) passes through the moisture absorbing part (26) and at least a part of the air supplied to the heat absorber (10). Is arranged so as to pass through the reproducing section (27).

  The first problem solving means has the following action. That is, in the first supply path (16), the air sucked into the main body (1) from the suction port (2) is supplied to the radiator (12) and heated by the heat radiation of the heat pump (13). At this time, at least a part of the air supplied to the radiator (12) is supplied to the moisture absorption part (26) of the dehumidification rotor (22).

  The air supplied to the moisture absorption part (26) is absorbed by moisture and the humidity is lowered, and the temperature rises due to the adsorption heat of the dehumidification rotor (22) and the residual heat of the heater (23), and the enthalpy increases. Since the air with increased enthalpy is supplied to the radiator (12), the operating pressure of the heat pump (13) increases. On the other hand, in the second supply path (17), air sucked into the main body (1) from the suction port (2) is supplied to the heat absorber (10) and is cooled and dehumidified by heat absorption of the heat pump (13). . At this time, at least a part of the air supplied to the heat absorber (10) is supplied to the regeneration unit (27) of the dehumidification rotor (22). The air supplied to the regeneration unit (27) is heated by the heater (23) and becomes high temperature, and the enthalpy increases. By supplying this high-temperature air to the regeneration unit (27), the dehumidification rotor (22) regenerates the moisture that has been absorbed into the high-temperature air. By containing the released moisture, the air is humidified and part of the sensible heat is converted into latent heat to become high-temperature and high-humidity air. Since this high-temperature, high-humidity air is supplied to the heat absorber (10), the enthalpy difference is expanded, high-efficiency heat absorption is performed, and the high-temperature, high-humidity air is cooled. The water saturated during this cooling process is recovered as condensed water. The condensed water includes both moisture absorbed by the dehumidification rotor (22) from the supply air in the moisture absorption section (26) and moisture removed by cooling the air supplied from the suction port (2) to the heat absorber (10). Is included.

  And the air heated with the heat radiator (12) and the air cooled and dehumidified with the heat absorber (10) are discharged | emitted from a blower outlet (4) outside a main body (1). In the above operation, the optimum air volume for heat radiation of the heat pump (13) does not necessarily match the optimum air volume for moisture absorption of the dehumidifying rotor (22).

  Therefore, by supplying a part of the air supplied to the radiator (12) to the moisture absorption part (26) so as to alleviate the difference between the optimum air volumes, the heat radiation of the heat pump (13) and the moisture absorption of the dehumidification rotor (22) can be reduced. It is done efficiently. Further, the air volume optimal for the heat absorption of the heat pump (13) does not necessarily match the air volume optimal for the regeneration of the dehumidifying rotor (22). Therefore, by supplying a part of the air supplied to the heat absorber (10) to the regenerator (27) so as to alleviate the difference between the optimum air volumes, the heat absorption of the heat pump (13) and the regeneration of the dehumidification rotor (22) can be performed. It is done efficiently.

It is discharged from the exhaust port (3) to the outside of the main body (1). Since the exhaust port (3) is opened on a surface different from the opening surface of the air outlet (4) of the main body (1), the air exhausted from the air outlet (4) and the air exhausted from the exhaust port (3) Are discharged in different directions. Therefore, it becomes difficult to mix the air discharged from the air outlet (4) and the air discharged from the exhaust port (3). Here, when the switching means (19) switches the discharge destination of the first supply path (16) to the exhaust port (3), from the exhaust port (3), the heat of adsorption of the dehumidification rotor (22), the heater (23 ) Residual heat and heat exhaust heat from the dehumidifier such as heat pump (13) is discharged, and the air outlet (4) is cooled by the heat absorption of the heat pump (13) that does not include the exhaust heat.

Stop or decrease By stopping or reducing the heat generation of the heater (23), the temperature rise of the air supplied to the heater (23) is reduced. Since the air whose temperature rise has been reduced is supplied to the regenerating unit (27), the dehumidifying rotor (22) is regenerated by the regenerating unit (27), and the temperature of the air converted from sensible heat to latent heat decreases. Since the air whose temperature has decreased is supplied to the heat absorber (10), the temperature of the air that has been cooled and dehumidified by the heat absorber (10) also decreases. Since this cooler air is discharged from the air outlet (4) or the exhaust port (3), the feeling of cold air is further improved.

  Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic cross-sectional view of a dehumidifier according to Embodiment 1 of the present invention.

  As shown in FIG. 1, a suction port 2 is formed on one side surface of a main body 1 formed in a substantially rectangular parallelepiped shape, an exhaust port 3 is formed above the suction port 2, and a blower port 4 is opened on a side surface opposite to the exhaust port 3. A filter 5 that captures foreign matter is provided on the opening surface of the mouth 2, and a wind direction changing means 6 that changes the air discharge direction is provided at the air outlet 4. Further, in the main body 1, a compressor 8 is disposed on the bottom plate 7, a heat absorber 10 is disposed above the compressor 8 via a support plate 9, and a heat radiator 12 is disposed above the heat absorber 10 via a partition wall 11, The compressor 8, the heat absorber 10, and the radiator 12 are connected by piping to form a sealed circuit, and a refrigerant that is a working fluid, for example, an HCFC refrigerant (chlorine, hydrogen, fluorine, carbon in the molecule) VFC), HFC refrigerant (including hydrogen, carbon and fluorine atoms in the molecule), natural refrigerants such as hydrocarbon and carbon dioxide, etc. are used to form a vapor compression heat pump 13 Yes.

  The heat absorber 10 and the radiator 12 are configured by a fin tube type heat exchanger in which a plurality of fins are inserted into a hairpin tube so as to allow air circulation, and in the pipe connecting the heat absorber 10 and the radiator 12. A not-shown throttling mechanism, for example, a capillary tube or an expansion valve is interposed.

  Further, when viewed from the suction port 2, the air blowing means 14 is disposed on the rear stage side of the radiator 12, and the air blowing means 15 is disposed on the rear stage side of the heat absorber 10. A supply path 16 and a second supply path 17 that is a blowing path of the blowing means 15 are formed separately. A general blower composed of a fan, a motor, a casing and the like is used for the blower unit 14 and the blower unit 15.

  The blowing means 14 communicates with the radiator 12 on the suction side and communicates with the blower outlet 4 on the discharge side. Therefore, when the blowing means 14 is activated, air is sucked from the suction port 2 and supplied to the radiator 12 to be blown out. The ventilation operation | movement discharged | emitted from 4 is performed. Further, since the air blowing means 15 communicates with the heat absorber 10 on the suction side and communicates with the air outlet 4 on the discharge side, when the air blowing means 15 is operated, air is sucked from the air inlet 2 and supplied to the heat absorber 10. The ventilation operation | movement discharged | emitted from the blower outlet 4 is performed.

  When the compressor 8 is operated here, the refrigerant circulates in the sealed circuit in the order of the radiator 12, the expansion mechanism (not shown), and the heat absorber 10, and the high-temperature and high-pressure refrigerant compressed by the compressor 8 blows in the radiator 12. The low-temperature and low-pressure refrigerant that has radiated heat to the air supplied by 14 and expanded by the expansion mechanism absorbs heat from the air supplied by the blower 15 in the heat absorber 10, and the heat pump 13 is activated.

  The air passage 18 that connects the air outlet 4 and the exhaust port 3 is provided with switching means 19 that switches the discharge destination of the first supply path 16 to either the air outlet 4 or the exhaust port 3. The switching means 19 has a damper mechanism that closes the air passage 18, and when the switching means 19 is set to the position A, the discharge side of the air blowing means 14 and the outlet 4 communicate with each other and the passage to the exhaust port 3 is blocked. It becomes a state. Moreover, when the switching means 19 is set to the position B, the discharge side of the air blowing means 14 and the exhaust port 3 communicate with each other and the passage to the air outlet 4 is closed. In this way, the switching means 19 is configured to switch the discharge destination of the first supply path 16 to either the blowout port 4 or the exhaust port 3. In order to change the position of the switching means 19, the operation unit 20 on the upper surface of the main body 1 may be provided with a lever portion interlocked with the damper mechanism and manually executed by the user, or an electric motor may be installed in the damper mechanism. May be executed by operating the electric motor with an operation button or the like provided on the operation unit 20. When the switching means 19 is manually operated by lever operation, a magnet is provided in the switching means 19, and a position detector 21 such as a Hall element is disposed at any position, for example, the position A side. It is preferable that 19 positions can be detected.

  A dehumidification rotor 22 is rotatably disposed on the windward side of the heat absorber 10 and the radiator 12 in the main body 1 so as to straddle the first supply path 16 and the second supply path 17. A heater 23 is arranged on the windward side of the rotor 22 on the second supply path 17 side. The dehumidifying rotor 22 is configured by supporting a hygroscopic agent on a cylindrical structure having a honeycomb structure or a corrugated structure capable of ventilating in the axial direction. The hygroscopic agent preferably has high hygroscopicity and has heat resistance that can withstand the heat generated by the heater 23 during regeneration. For example, an inorganic adsorption type hygroscopic agent such as silica gel or zeolite, an organic polymer electrolyte (ion For example, a hygroscopic agent such as an exchange resin) or an absorbent hygroscopic agent such as lithium chloride can be used. The hygroscopic agent is not limited to one type, and two or more types of the above-described hygroscopic agents may be used in combination. A drive motor 24 is connected to the rotating shaft portion of the dehumidification rotor 22, and the dehumidification rotor 22 rotates as the drive motor 24 rotates. At this time, the rotation speed of the dehumidification rotor 22 is set to about 10 to 40 rotations per hour.

  The heater 23 is disposed in the vicinity of the dehumidification rotor 22, and the air supplied to the dehumidification rotor 22 through the heater 23 and the dehumidification rotor 22 itself are heated by the heat generated by the heater 23. Further, a reflector 25 is disposed on the opposite side of the heater 23 from the dehumidifying rotor 22, and the radiant heat dissipated by the heater 23 is reflected by the reflector 25 to the dehumidifying rotor 22. The heater 23 may be capable of performing a heat generating operation. For example, a nichrome heater, a halogen heater, a carbon heater, a sheathed heater, a PTC heater, or the like can be used. In particular, when a PTC heater is employed, the heat generation amount is adjusted according to the air temperature supplied by the self-temperature controllability of the PTC heater, and the air temperature supplied to the dehumidifying rotor 22 is controlled to be substantially constant. Become. For example, when the temperature of the air supplied to the PTC heater is low, that is, in the winter, the amount of heat generated by the PTC heater increases and the power consumption increases, and when the temperature of the air supplied to the PTC heater is high, that is, in summer. However, the amount of heat generated by the PTC heater is reduced and the power consumption is also reduced. When the PTC heater is employed in this manner, a stable amount of heat can be supplied to the dehumidifying rotor 22 throughout the year. The reflecting plate 25 may be any material that can reflect the radiant heat dissipated by the heater 23, and can be formed by bending a glossy metal plate such as an aluminum plate or a stainless steel plate. Further, if the reflection plate 25 is formed so as to also fix the heater 23, the fixture for the heater 23 is not required, and the configuration can be simplified. Further, the reflection plate 25 can also act as a light shielding plate for blocking light emitted from the heat generation of the heater 23 from leaking from the suction port 2.

  Thus, since the dehumidification rotor 22 and the heater 23 are arrange | positioned in the upstream of the heat absorber 10 and the heat radiator 12, when the ventilation means 14 performs air blowing operation, the air attracted | sucked from the suction inlet 2 will be 1st supply. A part is supplied to the path 16, a part is supplied to the dehumidification rotor 22, and the rest is supplied to the radiator 12. Further, when the air blowing means 15 performs the air blowing operation, the air sucked from the suction port 2 is guided to the second supply path 17, a part is supplied to the dehumidifying rotor 22 through the heater 23, and the rest is the heat absorber 10. To be supplied. In this way, the dehumidification rotor 22 is in direct contact with the air sucked from the suction port 2 in the first supply path 16, and in the second supply path 17, the air heated to the high temperature by being heated by the heater 23. Contact with. The hygroscopic agent carried on the dehumidifying rotor 22 absorbs moisture from air with relatively high humidity and low temperature, and releases moisture to air with relatively low humidity and high temperature. The rotor 22 absorbs moisture from the air supplied in the first supply path 16, releases moisture to the air heated by the heater 23 in the second supply path 17, and is regenerated. Accordingly, a portion of the dehumidification rotor 22 located in the first supply path 16 serves as a moisture absorbing part 26 that absorbs moisture from the supply air, and a part located in the second supply path 17 releases the moisture to the supply air and regenerates it. Will work as 27. Furthermore, since the radiant heat dissipated by the heater 23 is supplied to the reproducing unit 27 by the reflector 25, moisture is more easily released, and the regeneration of the dehumidifying rotor 22 is promoted. Further, since the dehumidification rotor 22 is rotated by the drive motor 24, the moisture absorbent carried on the dehumidification rotor 22 continuously moves in the first supply path 16 and the second supply path 17, and in the moisture absorption section 26. The moisture absorption operation and the moisture release operation in the regeneration unit 27 are continuously performed.

  The air from which moisture has been removed by moisture absorption in the moisture absorption section 26 increases in temperature and enthalpy due to adsorption heat of the dehumidification rotor 22 and residual heat of the heater 23 and is supplied to the radiator 12 on the leeward side. By supplying the air with increased enthalpy to the radiator 12, the operating pressure of the heat pump 13 increases, and heat absorption capability can be ensured particularly at low temperatures such as in winter. In addition, the air from which moisture has been released in the regenerating unit 27 is in a high temperature and high humidity state, and the enthalpy increases and is supplied to the heat absorber 10 on the leeward side. Since this high enthalpy air is supplied to the heat absorber 10, the enthalpy difference is increased and a highly efficient heat absorption operation is performed, and the supplied air is cooled below its saturation temperature. Moisture saturated in this cooling process drops downward as condensed water, is received by a drain pan (not shown), and then stored in a drain tank 28 detachably disposed between the bottom plate 7 and the support plate 9. The condensed water includes both the moisture absorbed by the dehumidifying rotor 22 in the moisture absorbing section 26 and the moisture removed by cooling the air supplied directly from the suction port 2 to the heat absorber 10. Further, when a predetermined amount of condensed water accumulates in the drain tank 28, the float switch as the water level detecting means 29 operates, and the operation of the dehumidifier is stopped to prevent overflow from the drain tank 28.

  The air that has passed through the radiator 12 in the first supply path 16 becomes high-temperature air including exhaust heat such as adsorption heat in the moisture absorption section 26, residual heat of the heater 23, and heat dissipation of the heat pump 13 in the radiator 12. 14 is sucked. The hot air blown out from the blowing means 14 is discharged from the outlet 4 to the outside of the main body 1 when the switching means 19 is set at the position A, and when the switching means 19 is set at the position B, It is discharged from the exhaust port 3 to the outside of the main body 1. The low-temperature air cooled by passing through the heat absorber 10 in the second supply path 17 is sucked into the blower 15 and then discharged from the blower outlet 4 to the outside of the main body 1. Therefore, when the switching means 19 is set to the position B, only the low-temperature air that has passed through the heat absorber 10 is discharged from the outlet 4. Thus, the heater 23, the dehumidifying rotor 22, the radiator 12 and the heat absorber 10, the air blowing means 14, and the air blowing means 15 are arranged in order in the horizontal direction in the main body 1 in this order from the suction port 2 side. The air sucked into the first supply path 16 by the air 14 is sucked and discharged by the air blowing means 14 without greatly changing the wind direction, so that the ventilation resistance in the first supply path 16 is reduced and the air volume is secured. It becomes easy and the blowing noise is reduced. Further, the air sucked into the second supply path 17 by the air blowing means 15 is also sucked into the air blowing means 15 without greatly changing the direction of the air flow. Noise will be reduced.

  FIG. 2 is a schematic cross-sectional view of the inlet opening surface of the dehumidifier shown in FIG.

  As shown in FIG. 2, the dehumidification rotor 22 is disposed at the opening of the suction port 2 so that the entire circumference can be seen, and a heat absorber 10 and a radiator 12 are partly disposed on the back side of the suction port. 2 are arranged side by side in the vertical direction so as to face the two openings. A partition wall 11 that divides the first supply path 16 and the second supply path 17 is installed on the back surface of the dehumidifying rotor 22 so as to cross the opening surface of the suction port 2. 12 is held. Therefore, the upper side of the partition wall 11 is the first supply path 16, the lower side of the partition wall 11 is the second supply path 17, and the portion of the dehumidification rotor 22 disposed in the first supply path 16 is the moisture absorption part 26.

  The air volume ratio between the air directly supplied to the radiator 12 and the air supplied to the radiator 12 via the moisture absorbing portion 26 in the first supply path 16 can be designed as appropriate, but the heat dissipation of the heat pump 13 and the dehumidifying rotor 22 can be designed appropriately. In order to effectively absorb the moisture, it is desirable to supply 10% to 70% of the entire air supplied to the radiator 12 to the moisture absorbing portion 26. The adjustment of the supply ratio is relatively easy by adjusting the ratio of the area covered by the dehumidification rotor 22 in the front surface area of the entire radiator 12 when viewed from the suction port 2 side. In order to supply 50% of the air supplied to the entire device 12 to the moisture absorbing portion 26, it is sufficient to cover about 50% of the front surface area of the radiator 12 with the dehumidifying rotor 22. Also, instead of supplying all the air that has passed through the dehumidifying rotor 22 to the radiator 12, a part of the air that has passed through the moisture absorbing portion 26 of the dehumidifying rotor 22 is directly discharged outside the main body 1 by bypassing the radiator 12. You may comprise. In this case, the area of the partition wall 11 may be widened, an opening may be provided in the partition wall 11, and a part of the air that has passed through the moisture absorption part 26 may be directly sucked into the blowing means 14. With such a configuration, the enthalpy applied to the radiator 12 is reduced and the heat absorption / dissipation capability of the heat pump 13 at a low temperature is lowered. However, the operating pressure of the heat pump 13 can be lowered at a high temperature, and the compressor 8 It can save energy by reducing the amount of work.

  Further, a heater 23 is provided on the windward side of the dehumidifying rotor 22 located in the second supply path 17, and the heater 23 is held on the windward side of the heater 23 and the radiant heat of the heater 23 is dehumidified on the side of the dehumidifying rotor 22. A fan-shaped reflecting plate 25 that reflects the light is disposed. Therefore, the portion covered with the reflection plate 25 of the dehumidifying rotor 22 as viewed from the opening of the suction port 2 becomes the reproducing unit 27. The reflector 25 is preferably formed so as to cover the entire heater 23 when viewed from the opening of the suction port 2. With this configuration, the radiant heat of the heater 23 can be reflected to the dehumidifying rotor 22 without leaking, and the heater 23 Can be shielded from leaking from the inlet 2. Although the air volume ratio between the air directly supplied to the heat absorber 10 and the air supplied to the heat absorber 10 via the regeneration unit 27 in the second supply path 17 can be designed as appropriate, the heat absorption of the heat pump 13 and the dehumidification rotor 22 can be designed appropriately. In order to effectively perform the regeneration, it is desirable to supply 10% to 70% of the entire air supplied to the heat absorber 10 to the regeneration unit 27. This adjustment of the supply ratio is relatively easy by adjusting the ratio of the area covered by the reflector 25 in the front area of the entire heat sink 10 when viewed from the suction port 2 side. In order to supply 30% of the air supplied to the entire vessel 10 to the regenerating unit 27, about 30% of the front surface area of the heat absorber 10 may be covered with the reflector 25.

  In addition, on the upstream side and the downstream side of the regeneration unit 27 in the rotation direction of the dehumidification rotor 22 in the second supply path 17, regions for supplying air from the suction port 2 directly to the dehumidification rotor 22 are provided. The pre-stage side of the dehumidification rotor 22 is the preheating part 30, and the rear stage side of the regeneration part 27 is the cooling part 31 of the dehumidification rotor 22. The preheating unit 30 is supplied with air that is sucked from the suction port 2 and heated slightly when passing through the vicinity of the heater 23 to rise in temperature. When this air heats the dehumidification rotor 22, the amount of heat used for increasing the sensible heat of the dehumidification rotor 22 in the regeneration unit 27 is reduced, and the heat of the heater 23 is used more effectively for moisture release. In the cooling unit 31, cooling by the supply air of the dehumidifying rotor 22 heated by the heater 23 in the regeneration unit 27 is performed. Thereby, in the moisture absorption part 26 located in the latter stage of the rotation direction of the cooling part 31, the dehumidification rotor 22 can start moisture absorption from an early stage. As described above, the preheating unit 30 applies the residual heat of the heater 23 to the dehumidifying rotor 22 to speed up the regeneration operation of the dehumidifying rotor 22, and the cooling unit 31 removes the residual heat of the heater 23 and accelerates the moisture absorption operation of the dehumidifying rotor 22. . In order to efficiently absorb and regenerate the dehumidifying rotor 22, the area ratio of the hygroscopic portion 26, the regenerating portion 27, the preheating portion 30, and the cooling portion 31 may be set as follows. That is, as the central angle of the dehumidifying rotor 22, the angle formed by the moisture absorption part 26 is in the range of 120 to 270 degrees, the angle formed by the regeneration part 27 is in the range of 60 to 120 degrees, and the angles formed by the preheating part 30 and the cooling part 31 are What is necessary is just to set to the range of 0 degree to 90 degree | times.

  A drain pan 32 is disposed under the heat absorber 10 so as to cover the lower end of the heat absorber 10, and water droplets condensed by the heat absorber 10 are configured to drop onto the drain pan 32 without leakage. The lower surface of the drain pan 32 is inclined so as to guide the dropped water droplets to the drain port 33, and a water receiving portion of a drain tank 28 that stores the water droplets is disposed below the drain port 33. In this way, the heat absorber 10 is disposed below the radiator 12, the drain pan 32 is disposed below the heat absorber 10, and the drain tank 28 is disposed below the drain pan 32, so that the condensed water generated in the heat absorber 10 can be smoothly drained. It can be guided to 28 and recovered.

  Furthermore, a grip portion 34 that can be stored around the operation portion 20 is provided on the upper surface of the main body 1, and a plurality of movable portions 35 are provided on the lower surface of the main body 1 so that the main body 1 can be moved in a grounded state. As a result, when the user moves the main body 1, it is possible to move the main body 1 while holding the grip portion 34 while being in a grounded state, thereby improving transportability.

  In addition, a room temperature sensor 36 that detects the temperature of the air sucked from the suction port 2 and a humidity sensor 37 that detects the humidity of the air are disposed at the corner of the opening of the suction port 2. A regeneration thermistor 38 that detects the temperature on the leeward side of the regeneration unit 27 is disposed on the back surface, and a heater thermistor 39 that detects the temperature in the vicinity of the heater 23 is disposed on the back surface of the heater 23 of the reflector 25. A coil temperature sensor 40 for detecting the temperature of the heat absorber 10 is attached to the side pipe of the heat absorber 10, and the room temperature sensor 36, humidity sensor 37, regeneration thermistor 38, heater thermistor 39, and coil temperature sensor 40 are detected. Although not shown, the value is output to the control means.

  FIG. 3 is a diagram illustrating a schematic configuration of the operation unit 20 of the dehumidifier according to Embodiment 1 of the present invention.

  As shown in FIG. 3, the operation unit 20 is provided with a plurality of operation buttons and display lamps, and is provided with a lever unit 41 for operating the switching means 19. As shown in FIG. 1, the lever portion 41 is interlocked with the damper mechanism of the switching means 19. When the lever portion 41 is set to the “dehumidifying operation” position, the switching means 19 switches to the position A in FIG. 1. Thus, the discharge side of the blowing means 14 and the outlet 4 communicate with each other, and the passage to the exhaust port 3 is closed. When the lever portion 41 is set to the “cold air operation” position, the switching means 19 is switched to the position B in FIG. 1 so that the discharge side of the air blowing means 14 communicates with the exhaust port 3 and the passage to the air outlet 4 is blocked. It becomes a state.

  The operation button 42 is a main power on / off switch of the dehumidifier, and the dehumidifier can be operated by turning on the operation button 42. The operation button 43 is an operation changeover switch. By operating the operation button 43, three types of operation modes of “low temperature mode”, “standard mode”, and “automatic mode” can be selected. The selection state of the operation mode can be confirmed by the lighting state of the display lamp at the upper part of the operation button 43. The operation button 44 is a switch for setting a wind direction changing range of the wind direction changing means 6 disposed at the blower outlet 4. The wind direction changing means 6 includes a louver part that defines the wind direction of the air discharged from the outlet 4 and a drive part that changes the angle of the louver part. Then, the louver part angle change range by the drive unit is set by operating the operation button 44, and the air direction change range of the exhaust air from the blower outlet 4 is switched to three stages of wide angle, upward direction, and downward direction. The selection state of the wind direction change range can be confirmed by the lighting state of the display lamp at the upper part of the operation button 44. The operation button 45 is a switch for setting the timer operation of the dehumidifier. By operating the operation button 45, the operation of the dehumidifier can be stopped after 2, 4 and 8 hours. This off timer selection state can be confirmed by the lighting state of the display lamp above the operation button 45.

  The operation button 46 is a selection switch for an internal drying operation for drying water droplets generated inside the main body 1, particularly the heat absorber 10. While the internal drying operation is being performed, the display lamp in the operation button 46 is lit to allow visual confirmation. The display unit 47 displays the humidity state of the space in which the main body 1 is installed, and performs display in three stages of a high humidity state, an appropriate humidity state, and a low humidity state based on the detection value of the humidity sensor 37. It is. Further, the indicator lamp 48 detects abnormality by detecting whether the drain tank 28 is full or not installed by the water level detection means 29, and these abnormalities are detected by the water level detection means 29. In this case, the display lamp 48 is lit to notify the user. The display lamp 49 detects an abnormal state based on detection values of the regeneration thermistor 38, the heater thermistor 39, and the coil temperature sensor 40, and notifies the abnormality. When the abnormal state is detected, the display lamp 49 is turned on. I am trying to inform you.

  FIG. 4 is a control block diagram of the dehumidifier according to Embodiment 1 of the present invention.

  As shown in FIG. 4, the microcomputer as the control means 50 includes detection values of the room temperature sensor 36, the humidity sensor 37, the regeneration thermistor 38, the heater thermistor 39, the coil temperature sensor 40, the water level detection means 29, and the position detector 21. And the instruction content of the operation unit 20 is input, and the operation of the dehumidifier is controlled by controlling the operations of the compressor 8, the air blowing means 14, the air blowing means 15, the drive motor 24, the heater 23, and the wind direction changing means 6. Like to do. For example, when the wind direction change range of the wind direction changing unit 6 is instructed by operating the operation button 44 on the operation unit 20 during the operation of the dehumidifier, the angle at which the control unit 50 is instructed to drive the wind direction changing unit 6 It will be controlled to operate within the change range.

  FIG. 5 is a list showing control operations in each operation mode of the dehumidifier according to Embodiment 1 of the present invention. The control means 50 is programmed to execute the control operations shown in this list.

  As shown in FIG. 5, when the lever 41 on the operation unit 20 is set to the “dehumidifying operation” position, that is, when the switching unit 19 is switched to the position A, the position of the switching unit 19 is set to the position. The detector 21 detects and the control means 50 is set so that three operation modes of “low temperature mode”, “standard mode”, and “automatic mode” can be selected by operating the operation button 43. Here, when “low temperature mode” is selected, the control unit 50 operates the compressor 8, the blowing unit 14, the blowing unit 15, the drive motor 24, and the heater 23. Therefore, air is supplied from the suction port 2 to the first supply path 16 and the second supply path 17, and the dehumidification rotor 22 rotating by the drive motor 24 absorbs moisture from the supply air in the first supply path 16, and the second supply path In 17, the moisture desorbed by the dehumidifying rotor 22 is released from the air heated by the heater 23 and regenerated. The air that has passed through the dehumidification rotor 22 in the first supply path 16 rises in temperature due to the heat of adsorption and the residual heat of the heater 23, and is supplied to the radiator 12 together with the air directly supplied from the suction port 2. In the radiator 12, the refrigerant circulating by the operation of the compressor 8 radiates heat to the supply air. Since this supplied air includes air whose enthalpy has been increased in the moisture absorption section 26, the operating pressure of the heat pump 13 also increases under low temperature conditions such as winter. On the other hand, the air that has been released with moisture in the regeneration unit 27 of the second supply path 17 and becomes high temperature and humidity is supplied to the heat absorber 10 together with the air directly supplied from the suction port 2 and cooled by the heat absorption of the refrigerant. . The water saturated in the cooling process is collected in the drainage tank 28, and the air from which the water has been cooled and removed by the heat absorber 10 is discharged from the outlet 4 together with the air heated by the radiator 12 in the first supply path 16 to the outside of the main body 1. To be discharged.

  Further, when “standard mode” is selected by operating the operation button 43, it is further divided depending on the detection value of the room temperature sensor 36. When the detected value of the room temperature sensor 36 is a predetermined value, for example, less than 15 ° C., the same control operation as in the “low temperature mode” described above is performed. When the detection value of the room temperature sensor 36 is equal to or higher than a predetermined value, for example, 15 ° C. or higher, the compressor 8, the air blowing means 14, and the air blowing means 15 are activated, and the operations of the drive motor 24 and the heater 23 are stopped. As a result, the dehumidification rotor 22 does not perform the hygroscopic regeneration operation, and the dehumidifying operation of only the heat pump 13 is performed. That is, in the radiator 12, the refrigerant radiates heat to the air supplied from the suction port 2 through the first supply path 16, and in the heat absorber 10, from the air supplied from the suction port 2 through the second supply path 17. The refrigerant absorbs heat. And both the air which passed the heat radiator 12 and the heat absorber 10 is discharged | emitted from the blower outlet 4 to the main body 1 exterior. Here, the dehumidifying capacity of the heat pump 13 greatly depends on the room temperature condition, and the dehumidifying capacity tends to increase as the temperature increases. Therefore, when the room temperature is detected by the room temperature sensor 36 and the detected value is a predetermined value, which is 15 ° C. or higher in this example, the dehumidifying operation is performed only by the heat pump 13, thereby reducing the energy input to the heater 23 and improving the efficiency. Good dehumidification can be performed. Further, in the dehumidifying operation using only the heat pump 13, the temperature of the air discharged from the outlet 4 is lower than when the dehumidifying rotor 22 and the heater 23 are operated. Therefore, when the detected value of the room temperature sensor 36 is equal to or higher than a predetermined value, for example, 15 ° C. or higher, the temperature discharged from the outlet 4 is lowered to suppress the rise in the room temperature. Then, a temperature adjusting operation for raising the discharge temperature from the outlet 4 and raising the room temperature is performed. As a result, the temperature of the room in which the main body 1 is placed is adjusted to a desired region, that is, around 15 ° C.

  Further, when the “automatic mode” is selected by operating the operation button 43, it is further divided depending on the detection value of the humidity sensor 37. When the detected value of the humidity sensor 37 is a predetermined value, for example, 55% or more, the same control operation as in the “standard mode” described above is performed, and the compressor 8 and the air blowing means are operated when the room temperature is lower than the predetermined value, that is, lower than 15 ° C. 14, the air blowing means 15, the drive motor 24, and the heater 23 are operated, and when the room temperature is equal to or higher than a predetermined value, that is, 15 ° C. or higher, only the compressor 8, the air blowing means 14, and the air blowing means 15 are operated to perform the dehumidifying operation only for the heat pump 13. Done. When the detected value of the humidity sensor 37 is a predetermined value, for example, less than 55%, it is determined that the humidity is appropriate and the dehumidifying operation is stopped. That is, all the operations of the compressor 8, the blowing unit 14, the blowing unit 15, the drive motor 24, and the heater 23 are stopped and the standby state is set. If the humidity increases due to the stop of the dehumidifying operation and the detected value of the humidity sensor 37 reaches a predetermined value, for example, 55% or more, the dehumidifying operation is resumed. Thus, in the “automatic mode”, the humidity adjustment operation is performed based on the detection value of the humidity sensor 37, and the humidity of the space where the main body 1 is placed is in a desired region, that is, around 55%. Will be adjusted.

  When the lever 41 on the operation unit 20 is set to the “cold air operation” position, that is, when the switching unit 19 is switched to the position B, the position detector 21 indicates the position of the switching unit 19. Detecting and operating the operation button 43 by the control means 50, two kinds of operation modes of “standard mode” and “automatic mode” are set to be selectable, and “low temperature mode” is set to be unselectable. Here, when “standard mode” is selected, the control unit 50 operates the compressor 8, the blowing unit 14, and the blowing unit 15. As a result, air is supplied from the suction port 2 to the first supply path 16 and the second supply path 17. In the first supply path 16, the refrigerant dissipates heat to the supply air in the radiator 12, and in the second supply path 17, In the heat absorber 10, the refrigerant absorbs heat from the supply air. Therefore, high-temperature air heated by the radiator 12 is discharged from the exhaust port 3 as the discharge destination of the first supply path 16, and cooled by the heat absorber 10 from the outlet 4 as the discharge destination of the second supply path 17. The low temperature air is discharged. The user can obtain a cold wind feeling by this low-temperature air.

  Further, when “automatic mode” is selected by operating the operation button 43, it is classified according to the detection value of the humidity sensor 37. When the detected value of the humidity sensor 37 is not less than a predetermined value, for example, 55% or more, the same control operation as that in the “standard mode” described above is executed, and the detected value of the humidity sensor 37 is less than the predetermined value, for example, 55%. If it is less than that, it is determined that the humidity is appropriate and the dehumidifying operation is stopped. That is, the operation of the compressor 8, the air blowing means 14, and the air blowing means 15 is stopped and a standby state is entered. If the humidity increases due to the stop of the dehumidifying operation and the detected value of the humidity sensor 37 is equal to or higher than a predetermined value, that is, 55% or higher, the dehumidifying operation is restarted. As described above, in the “automatic mode”, the humidity adjustment operation is performed based on the detection value of the humidity sensor 37 as in the “dehumidifying operation”, and the humidity of the space in which the main body 1 is placed is desired. That is, it is adjusted to about 55%. As described above, when the lever portion 41 is set to the “cold air operation” position, the heater 23 does not operate regardless of which mode is selected with the operation button 43, so that the heat absorber 10 is cooled from the outlet 4. In addition, air having a temperature lower than room temperature is always supplied, and the feeling of cold wind is always maintained.

  When the “internal drying” operation is set by operating the operation button 46, the control unit 50 operates the blowing unit 14, the blowing unit 15, the drive motor 24, and the heater 23 to stop only the compressor 8. To do. When the compressor 8 is stopped, the heat pump 13 is not operated, and the cooling and dehumidifying operation from the supply air in the heat absorber 10 is stopped, and water droplets are not generated. The high-temperature air heated by the heater 23 is supplied to the heat absorber 10 through the dehumidifying rotor 22 to dry the condensed water droplets remaining on the heat absorber 10. Here, when a heater having a strong radiation component, such as a nichrome heater, is used as the heater 23, the temperature of the dehumidification rotor 22 located in the regenerating unit 27 and the leeward side temperature of the regenerating unit 27 while the rotation of the dehumidifying rotor 22 is stopped. Rises to an abnormal temperature, for example, 80 ° C. or higher, so that the heat of the heater 23 accumulated in the dehumidification rotor 22 is discharged to the first supply path 16 by operating the drive motor 24 and the air blowing means 14 and the vicinity of the regeneration unit 27. The temperature rise is suppressed. If the dehumidification rotor 22 is continuously rotated here, the moisture absorption / release operation is always performed in which the moisture absorbed by the moisture absorption unit 26 is released by the regeneration unit 27, so that the air supplied to the heat absorber 10 becomes highly humid. Drying efficiency may deteriorate. In such a case, it is effective to suppress the moisture absorption / release of the dehumidification rotor 22 by operating the drive motor 24 intermittently. The timing of this intermittent operation may be set by a timer or may be determined based on the temperature detected by the regeneration thermistor 38 provided leeward of the regeneration unit 27. For example, when the detection temperature of the regeneration thermistor 38 is equal to or higher than a set value, for example, 80 ° C. or higher, the drive motor 24 is operated to rotate the dehumidification rotor 22, and the detected temperature of the regeneration thermistor 38 is lower than the set value, for example, 80 ° C. If less, the drive motor 24 may be stopped to stop the rotation of the dehumidifying rotor 22.

  As described above, the control means 50 controls the compressor 8, the air blowing means 14, the air blowing means 15, the drive motor 24, and the heater 23 according to each operation mode, so that various operations suitable for the use environment and the user's preference are performed. A form can be realized.

  FIG. 6 is a graph showing the dehumidification capability characteristics in each operation mode of the dehumidifier of Embodiment 1 of the present invention.

  In the graph of FIG. 6, the horizontal axis represents the temperature of the room where the dehumidifier is installed, and the vertical axis represents the dehumidifying capacity. The broken line data indicates the dehumidifying ability characteristic when the lever part 41 is switched to “dehumidifying operation” and the “low temperature mode” is set with the operation button 43, and the dotted line data indicates that the lever part 41 is switched to “cold air operation”. Dehumidification capability characteristics when “standard mode” is set with the operation button 43, and solid line data are dehumidification capability characteristics when the lever unit 41 is switched to “dehumidification operation” and “standard mode” is set with the operation button 43. . As shown in FIG. 6, in the “cold air operation”-“standard mode”, the dehumidification capability is high due to dehumidification only by the endothermic action of the heat pump 13, and the dehumidification capability is greatly reduced particularly under low temperature conditions. In the “dehumidifying operation”-“low-temperature mode”, the heater 23 and the drive motor 24 are operated to add the moisture absorbing / releasing action of the dehumidifying rotor 22 to improve the dehumidifying ability. In particular, under low-temperature conditions, the operating pressure of the heat pump 13 is increased by supplying air to the radiator 12 that has increased in temperature due to adsorption heat of the dehumidifying rotor 22 and residual heat of the heater 23, and heating is performed in the heater 23 and the regeneration unit 27. By supplying humidified high enthalpy air to the heat absorber 10, it is possible to secure a difference in enthalpy from the refrigerant in the heat absorber 10 and suppress a decrease in the dehumidifying capacity. In the “dehumidifying operation”-“standard mode”, the heater 23 and the drive motor 24 are operated when the detected value of the room temperature sensor 36 is less than 15 ° C., and the heater 23 and the drive motor 24 are stopped when the detected value is 15 ° C. or more. Accordingly, when the room temperature is less than 15 ° C., the same dehumidifying ability as “dehumidifying operation”-“low temperature mode” is obtained, and when the room temperature is 15 ° C. or more, the same ability as “cold air operation” — “standard mode” is obtained. Thus, by controlling based on the detection value of the room temperature sensor 36, stable dehumidification can be performed throughout the year regardless of temperature conditions.

  FIG. 7 is a list showing detection of various abnormal modes of the dehumidifier according to Embodiment 1 of the present invention and control operations at that time. The control means 50 is programmed to execute the control operations shown in this list.

  As shown in FIG. 7, when the drain tank 28 is full or when the drain tank 28 is not installed, the water level detection means 29 detects the water level abnormality of the drain tank 28, and the control means 50 is based on this detection result. However, the display lamp 48 is turned on to notify the abnormality, and the operation of the compressor 8, the blowing unit 14, the blowing unit 15, the drive motor 24, and the heater 23 is stopped. As a result, the dehumidifying operation is stopped and the overflow of condensed water is prevented.

  In addition, when a problem occurs in the rotation of the dehumidification rotor 22, for example, when the dehumidification rotor 22 is derailed or the drive motor 24 malfunctions, the temperature on the leeward side of the regeneration unit 27 increases. This temperature rise is detected by the regeneration thermistor 38, and when the detected temperature of the regeneration thermistor 38 becomes a predetermined value or higher, for example, 80 ° C. or higher, the control means 50 turns on the display lamp 49 to notify the abnormality and compresses the temperature. The operation of the machine 8, the drive motor 24, and the heater 23 is stopped to suppress further temperature rise. Then, after the air blowing means 14 and the air blowing means 15 are operated for a predetermined time, for example, 1 minute, and the heat in the main body 1 is discharged to the outside, the air blowing means 14 and the air blowing means 15 are stopped to shift to a standby state. As a result, the temperature increase on the leeward side of the reproducing unit 27 is suppressed. In this way, the temperature of the regeneration unit 27 leeward side is detected by the regeneration thermistor 38. When the detected value is less than a predetermined value, for example, less than 80 ° C., that is, when the dehumidifying rotor 22 rotates without any problem, the heater 23 And the dehumidifying rotor 22 increases the dehumidifying capacity by the moisture absorbing / releasing action. When the detected value is equal to or higher than a predetermined value, for example, 80 ° C. or higher, it is determined that the rotation of the dehumidifying rotor 22 has failed. The control operation is performed to suppress the temperature increase on the leeward side of the regeneration unit 27 and to ensure the temperature reliability.

  Further, when a problem occurs in the blowing operation of the blowing means 14, for example, when a malfunction of the fan motor occurs, air is not supplied to the radiator 12, so that the refrigerant cannot radiate heat and the pressure on the high pressure side of the heat pump 13 is increased. And the temperature rises. This temperature rise is detected by a thermostat provided in the compressor 8, and based on the detection result, the control means 50 turns on the display lamp 49 to notify the abnormality, and the compressor 8, the drive motor 24, and the heater 23. The operation is stopped to suppress further pressure and temperature rise of the heat pump 13. And after operating the ventilation means 15 for a predetermined time, for example, 1 minute, and discharging the heat | fever in the main body 1 outside, the ventilation means 15 is stopped and it transfers to a standby state. As a result, the pressure rise and temperature rise of the heat pump 13 are suppressed.

  In addition, when a problem occurs in the blowing operation of the blowing unit 15, for example, when the heater 23 is operated when a malfunction of the fan motor occurs, there is no ventilation to the heater 23 and the temperature in the vicinity of the heater 23 rises. To do. This temperature rise is detected by the heater thermistor 39, and when the detected temperature of the heater thermistor 39 becomes a predetermined value or higher, for example, 105 ° C. or higher, the control means 50 turns on the display lamp 49 to notify the abnormality and compresses The operation of the machine 8, the drive motor 24, and the heater 23 is stopped to suppress further temperature rise. And after operating the ventilation means 14 for a predetermined time, for example, 1 minute, and discharging the heat | fever in the main body 1 outside, the ventilation means 14 is stopped and it transfers to a standby state. As a result, the temperature rise near the heater 23 is suppressed. In this way, the heater thermistor 29 detects the temperature in the vicinity of the heater 23, and when the detected value is less than a predetermined value, for example, less than 105 ° C., that is, when the blowing operation of the blowing means 15 is performed without any problem. 23, the dehumidifying capacity of the dehumidifying rotor 22 is increased and the dehumidifying capacity is increased, and when the detected value is equal to or higher than a predetermined value, for example, 105 ° C. or higher, it is determined that a problem has occurred in the blowing operation of the blowing means 15; A control operation is performed in which the operation of the heater 23 is stopped to suppress temperature rise in the vicinity of the heater 23 to ensure temperature reliability.

  In addition, when a failure occurs in the air blowing operation of the air blowing means 15 when the heater 23 is stopped, air is not supplied to the heat absorber 10, so that the refrigerant cannot absorb heat and the pressure and temperature of the heat absorber 10 decrease. This temperature drop is detected by the coil temperature sensor 40 provided in the side pipe of the heat absorber 10, and based on the detection result, the control means 50 lights up the display lamp 49 to notify the abnormality, and the compressor 8 and The air blower 14 is stopped and the operation of the heat pump 13 is stopped. Thereby, the pressure drop of the heat pump 13 is suppressed, and freezing of the heat absorber 10 is suppressed.

  Further, when the dehumidifying operation of only the heat pump 13 is performed under the low temperature condition, that is, the “cold air operation” is performed, the heat absorber 10 is frosted, the heat absorbing capacity 10 of the heat pump 13 is lowered, and the temperature of the heat absorber 10 gradually increases. descend. This temperature drop is detected by the coil temperature sensor 40 provided in the side pipe of the heat absorber 10, and the control means 50 when the detected temperature of the coil temperature sensor 40 is less than a first set value, for example, less than 1 ° C. Activates the heater 23 and the drive motor 24, and supplies the heat amount of the heater 23 to the heat absorber 10 and the radiator 12 through the dehumidifying rotor 22. As a result, high-temperature air is supplied to the heat absorber 10, and the operating pressure of the heat pump 13 is increased, so that the operation for removing frost attached to the heat absorber 10 is performed. When the frost is sufficiently removed by this removal operation, the temperature of the heat absorber 10 rises, and the detected temperature of the coil temperature sensor 40 is restored to the first set value or higher, for example, 1 ° C. or higher. When the detected temperature is thus recovered, the control means 50 stops the heater 23 and the drive motor 24 and restarts the “cold air operation” again. If the frost cannot be sufficiently removed even if the above-described removal operation is performed and the temperature of the heat absorber 10 further decreases, this temperature decrease is detected by the coil temperature sensor 40, and this detected temperature is the first setting. When it becomes less than a second set value lower than the value, for example, less than −3 ° C., the control means 50 stops the compressor 8. Thereby, the operation of the heat pump 13 is stopped, the heat absorbing operation in the heat absorber 10 is stopped, and the temperature of the heat absorber 10 is increased. Furthermore, since the air heated by the heater 23 is supplied to the heat absorber 10 through the dehumidification rotor 22, the removal of frost attached to the heat absorber 10 is promoted. When the frost in the heat absorber 10 is completely removed and the temperature of the heat absorber 10 is restored to a predetermined value or higher, for example, 1 ° C. or higher, the control unit 50 operates the compressor 8 again to restart the operation of the heat pump 13. In this way, a control operation for efficiently removing frost attached to the heat absorber 10 at a low temperature is performed.

  FIGS. 8A, 8B, and 8C are schematic diagrams illustrating usage patterns of the dehumidifier according to Embodiment 1 of the present invention.

  Fig.8 (a) has shown the usage pattern in the case of drying the laundry 51 dried indoors using the dehumidifier of Embodiment 1 of this invention. In this case, it is preferable to switch the switching means 19 to the position A and set the discharge destination of the first supply path 16 to the outlet 4. With this setting, since the air discharged from the first supply path 16 and the air discharged from the second supply path 17 are both discharged from the blowout port 4, the air volume and wind speed from the blowout port 4 are increased. The laundry 51 becomes easier to dry. And if the wind direction is adjusted so that the wind reaches the whole laundry 51 by the wind direction changing means 6 with the air outlet 4 directed toward the laundry 51, the laundry 51 can be dried more effectively. Moreover, it is preferable that the set operation mode is a “low temperature mode”. As a result, the moisture absorbing / releasing action of the dehumidifying rotor 22 is always performed, so that the dehumidifying capacity increases and the laundry 51 dries faster.

  FIG.8 (b) has shown the usage form when the user 52 wants to obtain a cool wind feeling after bathing etc. using the dehumidifier of Embodiment 1 of this invention. In this case, it is preferable to switch the switching means 19 to the position B and set to “cold air operation”. When set in this way, the operation of the heater 23 is stopped, and the indoor air sucked from the suction port 2 in the second supply path 17 is absorbed by the heat absorber 10 to become a temperature lower than room temperature and is discharged from the outlet 4. The By supplying this low-temperature air toward the user 52 by the wind direction changing means 6, the user 52 can obtain a cold wind feeling. Further, the air heated by the heat radiation of the radiator 12 in the first supply path 16 is discharged from the exhaust port 3 opened on the opposite surface of the blower outlet 4. As a result, the hot air discharged from the exhaust port 3 is less likely to be mixed with the low-temperature air discharged from the air outlet 4, and the cold wind feeling is further improved.

  FIG. 8C is a diagram in which an exhaust duct 53 is connected to the exhaust port 3 in the operation mode shown in FIG. 8B using the dehumidifier of Embodiment 1 of the present invention. Thereby, the high temperature air exhausted from the exhaust port 3 can be exhausted to a space other than the room where the user 52 is located, for example, the outdoor. Thereby, not only the low temperature air is supplied to the user 52 from the blower outlet 4 to give a cool air feeling, but also the temperature of the space where the user 52 exists can be lowered. The exhaust duct 53 is preferably detachably disposed on the exhaust port 3 by screwing or sliding insertion. If comprised in this way, it will become easy to change to a usage pattern that does not use the exhaust duct 53, for example, the usage pattern shown in FIGS. 8A and 8B, and the exhaust duct 53 is removed and stored. So you can save space.

  As described above, with the configuration and operation described above, the dehumidifier of the present embodiment has the following effects.

  Since the moisture absorbed by the dehumidifying rotor 22 is collected as condensed water by the heat absorber 10, a sensible heat exchanger for collecting water becomes unnecessary, and the apparatus can be miniaturized.

  Moreover, since the dehumidifying operation by the heat pump 13 and the dehumidifying rotor 22 is possible without forming an annular circulation air passage in the apparatus, the apparatus configuration can be simplified.

  In addition, since air with increased enthalpy due to the heat of adsorption of the dehumidifying rotor 22 and the residual heat of the heater 23 is supplied to the radiator 12, the operating pressure of the heat pump 13 rises, and the heat absorption capacity is maintained even at low temperatures in winter, and the amount of dehumidification is increased. Can be secured.

  Moreover, since the high enthalpy air heated and humidified by the heater 23 and the regenerating unit 27 of the dehumidifying rotor 22 is supplied to the heat absorber 10, the enthalpy difference can be expanded and an efficient dehumidifying operation can be performed.

  Further, by supplying a part of the air supplied to the radiator 12, for example, 10% to 70%, to the moisture absorption part 26, the difference between the amount of air suitable for heat dissipation of the heat pump 13 and the volume of air suitable for moisture absorption of the dehumidifying rotor 22 It is possible to relax and efficiently dissipate heat from the heat pump 13 and absorb moisture from the dehumidifying rotor 22.

  Further, by supplying the regeneration unit 27 with a part of the air supplied to the heat absorber 10, for example, 10% to 70%, the difference between the air volume suitable for heat absorption of the heat pump 13 and the air volume suitable for regeneration of the dehumidifying rotor 22. The heat absorption of the heat pump 13 and the regeneration of the dehumidifying rotor 22 can be efficiently performed.

  Further, the switching means 19 switches between the heat of adsorption of the dehumidification rotor 22, the residual heat of the heater 23, the exhaust air of the dehumidifier such as heat dissipation of the heat pump 13, and the discharge destination of the low-temperature air cooled by the heat absorption of the heat pump 13. Therefore, the operation mode in which both the high-temperature air containing exhaust heat and the cooled low-temperature air are supplied from the outlet 4, that is, the “dehumidifying operation” mode, and the cooled low-temperature air from the outlet 4 are provided. It is possible to switch to an operation mode in which high-temperature air including exhaust heat is supplied and exhausted from the exhaust port 3, that is, a “cold air operation” mode. Thereby, the user can select the driving mode according to his / her preference, and the usability can be improved.

  Moreover, since the blower outlet 4 and the exhaust port 3 were opened in the different surface of the main body 1, the air discharged from the blower port 4 and the air discharged from the exhaust port 3 are not easily mixed, and the low temperature cooled from the blower port 4 In the “cold air operation” mode in which only air is supplied, the user can obtain a cool air feeling.

  Further, when the switching unit 19 sets the discharge destination of the first supply path 16 to the exhaust port 3, that is, when the “cold air operation” mode is set, the heat generation of the heater 23 is stopped. It is possible to further improve the cool wind feeling by lowering the temperature of the air.

  Moreover, since the air discharged from the exhaust port 3 can be discharged far away from the blower outlet 4 by the exhaust duct 53, the cool air feeling can be further improved. Further, when the air from the exhaust port 3 is discharged to a space different from the space where the main body 1 is disposed by the exhaust duct 53, only the cooled low-temperature air is supplied to the space where the main body 1 is placed. The space temperature can be adjusted.

  Further, in the first supply path 16, a part of the air sucked into the main body 1 from the suction port 2 can be smoothly supplied to the dehumidification rotor 22 and the radiator 12 arranged in parallel in the horizontal direction without changing the direction. it can. Thereby, the ventilation resistance of the 1st supply path | route 16 reduces, air volume ensuring becomes easy, and noise reduction can be achieved.

  Further, in the second supply path 17, a part of the air sucked into the main body 1 from the suction port 2 is smoothly supplied to the heater 23, the dehumidifying rotor 22 and the heat absorber 10 arranged in parallel in the horizontal direction without changing the direction. can do. Thereby, the ventilation resistance of the 2nd supply path 17 reduces, air volume ensuring becomes easy, and noise reduction can be achieved.

  Further, since the heat absorber 10 is disposed below the radiator 12, the condensed water generated in the heat absorber 10 can be collected smoothly without being re-dissipated by the radiator 12.

  In addition, when a heater having self-temperature controllability, for example, a PTC heater, is used as the heater 23, the air temperature supplied to the regeneration unit 27 is controlled to be substantially constant, and the regeneration unit 27 always performs stable moisture release. Can do. Therefore, stable dehumidification performance can be ensured throughout the year. Furthermore, since the power consumption of the heater 23 is adjusted according to the supplied air temperature, energy saving can be improved.

  Moreover, since the radiant heat dissipated by the heater 23 is reflected by the reflecting plate 25 to the regenerating unit 27 of the dehumidifying rotor 22, the amount of moisture released from the regenerating unit 27 can be increased. As a result, the amount of condensed water recovered in the heat absorber 10, that is, the dehumidified amount can be increased.

  Further, since the reflection plate 25 is disposed so as to cover the entire surface of the heater 23 when viewed from the suction port 2 side, it is possible to shield light emitted from the heater 23 from leaking from the suction port 2.

  Further, when the value of the room temperature sensor 36 that detects the temperature of the air sucked from the suction port 2 is equal to or higher than a predetermined value, for example, 15 ° C. or higher, the heater 23 and the drive motor 24 are stopped and the dehumidifying rotor 22 performs moisture absorption / release operation. Since the heater 23 and the drive motor 24 are operated when the value of the room temperature sensor 36 is less than a predetermined value, for example, less than 15 ° C., a “standard mode” for performing the moisture absorption / release operation of the dehumidification rotor 22 is provided. The temperature of the room in which the main body 1 is placed can be adjusted to a desired region, for example, around 15 ° C. Furthermore, a stable dehumidifying ability can be obtained throughout the year.

  Further, when the value of the humidity sensor 37 for detecting the humidity of the air sucked from the suction port 2 is less than a predetermined value, for example, less than 55%, the heater 23 and the drive motor 24 are stopped and the moisture removal / desorption operation of the dehumidifying rotor 22 is performed. And the operation of the heat pump 13 is stopped. When the value of the humidity sensor 37 is equal to or higher than a predetermined value, for example, 55% or higher, the heater 23 and the drive motor 24 are operated to perform the moisture absorption / release operation of the dehumidifying rotor 22. Since the “automatic mode” in which the heat pump 13 is operated to perform the dehumidifying operation is provided, the humidity of the room in which the main body 1 is placed can be adjusted to a desired region, for example, around 55%.

However, the switching pattern of the switching means 19 is not limited to the above two stages. For example, it may be configured to be set at an intermediate position C between the position A and the position B, and the discharge destination of the first supply path 16 may be set to both the outlet 4 and the outlet 3. In this case, a part of the air discharged from the blower means 14 is discharged from the blowout port 4 and the rest is discharged from the exhaust port 3. Various switching patterns such as two-step switching between position A and position C, two-step switching between position B and position C, and three-step switching between position A, position B and position C are applied to the switching pattern of switching means 19. Can do it.

  In the above embodiment, the switching unit 19 is configured to be able to switch the discharge destination of the first supply path 16 to the outlet 4 or the exhaust port 3. However, the switching unit 19 allows the outlet of the second supply path 17 to be blown. You may comprise so that it may switch to the exit 4 or the exhaust port 3. FIG. When the discharge destination of the second supply path 17 is switched to the exhaust port 3, a high temperature including exhaust heat such as adsorption heat of the dehumidification rotor 22, residual heat of the heater 23, and heat dissipation of the heat pump 13 is discharged from the outlet 4.

Further, the switching means 19 may be configured to be able to individually switch the discharge destination of each of the first supply path 16 and the second supply path 17 to either the outlet 4 or the outlet 3. In this case, it is possible to supply low-temperature air cooled by the heat absorber 10, high-temperature air including exhaust heat from the dehumidifier, or both low-temperature air and high-temperature air from the air outlet 4. , The usability can be further improved.

  Moreover, in the said embodiment, although the drive motor 23 was connected with the rotating shaft part of the dehumidification rotor 22, and it comprised so that rotation operation of the dehumidification rotor 22 might be performed, the structure which rotates the dehumidification rotor 22 is restricted to this. is not. For example, a part in which a gear is formed on the outer periphery of the dehumidifying rotor 22 may be disposed, and the drive motor 23 may be connected to the gear to rotate the dehumidifying rotor 22. Alternatively, a belt may be put on a gear provided around the belt, and the drive motor 23 may be connected via the belt to rotate the dehumidifying rotor 22.

  In the above embodiment, the heater 23 and the drive motor 24 are stopped when the detection value of the room temperature sensor 36 is less than a predetermined value, that is, less than 15 ° C., and the detection value of the room temperature sensor 36 is equal to or more than the predetermined value, that is, 15 ° C. or more. The heater 23 and the drive motor 24 are operated to perform the two-stage control for performing the moisture absorption / release operation of the dehumidification rotor 22. However, the setting of the predetermined value and the number of control stages are not limited thereto. For example, the output of the heater 23 can be set in two stages of large and small, the value of the room temperature sensor 36 is less than a first predetermined value, for example, less than 10 ° C., the output of the heater 23 is large, and the value of the room temperature sensor 36 Is less than the first predetermined value and less than the second predetermined value, for example, 10 ° C. or more and less than 20 ° C., the output of the heater 23 is small, and the value of the room temperature sensor 36 is the second predetermined value or more, for example, 20 ° C. or more. For example, the setting method of the predetermined value according to the detection value of the room temperature sensor 36 and the number of control steps can be various.

  In the above embodiment, the heater 23 and the heat pump 13 are stopped when the detected value of the humidity sensor 37 is less than a predetermined value, that is, less than 55%, in the “dehumidifying operation”, and the detected value of the humidity sensor 37 is equal to or higher than the predetermined value. Although the two-stage control is performed to operate the heater 23 and the heat pump 13 at 55% or more, the setting method of the predetermined value, the number of control stages, and the control operation are not limited to this. For example, the heater 23 and the heat pump 13 are stopped when the value of the humidity sensor 37 is less than a first predetermined value, for example, less than 50%, and the value of the humidity sensor 37 is greater than or equal to a first predetermined value and less than a second predetermined value, for example, 50% or more and less than 60%, only the heat pump 13 is operated, and when the value of the humidity sensor 37 is the second predetermined value or more, for example, 60% or more, both the heater 23 and the heat pump 13 are operated to absorb heat and dehumidify. Dehumidification may be performed rapidly by the moisture absorbing / releasing action of the rotor 22. Thus, the setting method of the predetermined value according to the detection value of the humidity sensor 37, the number of control steps, and the control operation can be variously configured.

  In the above embodiment, the heater 23 is controlled to be stopped when the switching unit 19 is set to the position B, that is, when the “cold air operation” is set. When the switching means 19 is set to the position B in such a configuration as possible, the output of the heater 23 may be controlled to decrease. In that case, the moisture absorption / release action of the dehumidification rotor 22 may be continued by rotating the drive motor 24.
