Description

  The present invention relates to a dehumidifying / humidifying device.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2003-294277) discloses a humidifier using both a heater heating type and a vaporization type. The humidifier of Patent Document 1 mainly includes a blower, a water tank, a rotary humidifying filter, and a heater. Water is supplied into the water tank from a water tank for supplying water from the outside, and the water is stored in the water tank. A part of the humidifying filter is immersed in the water tank, and water is distributed throughout the humidifying filter by rotation. The heater heats the wind from the blower to generate warm air and supplies it to the humidifying filter. The water absorbed by the humidifying filter is vaporized by the warm air and becomes humidified air and is discharged outside the humidifier. Thus, patent document 1 is disclosing the structure humidified more efficiently in a humidifier.

  In recent years, dehumidifying / humidifying devices having both dehumidifying and humidifying functions have been developed. However, in such a dehumidifying / humidifying device, a configuration for improving the humidifying performance has not been proposed.

  Then, the objective of this invention is providing the dehumidification / humidification apparatus which can improve humidification performance.

The motor-operated valve is provided between the evaporator and the radiator. During the humidification operation, the control unit adjusts the temperature of the evaporator by adjusting the opening of the motor-operated valve, and suppresses dehumidification in the evaporator.

  In the above configuration, the control unit adjusts the opening degree of the motor-operated valve provided between the evaporator and the radiator during the humidifying operation. Therefore, the dew condensation start point in the evaporator is shifted backward, and dehumidification in the evaporator can be suppressed. As a result, it is possible to suppress a decrease in humidification capacity.

The first discharge unit 11a and the second discharge unit 11b are provided in the vicinity of the first side suction port 113a and the second side suction port 113b, respectively. Therefore, the air taken in from the first side suction port 113a passes through the first discharge unit 11a, and the air taken in from the second side suction port 113b passes through the second discharge unit 11b. The 1st discharge unit 11a contains the ionization wire made from tungsten which is a positive electrode, and the plate-shaped electrode made from stainless steel which is a negative electrode. When a high voltage is applied to the ionization wire that is the positive electrode, a potential difference is generated between the positive electrode and the negative electrode, and corona discharge occurs. Dust in the air passing through the first discharge unit 11a is charged by this discharge. Since the structure of the 2nd discharge unit 11b is the same as that of the 1st discharge unit 11a, description is abbreviate | omitted.

  The discharge streamer body 13a has a needle-like electrode made of tungsten that is a positive electrode and a plate-like electrode (counter electrode) that is located in the vicinity of the needle-like electrode and faces the electrode. By applying a high voltage to the needle-like electrode, streamer discharge, which is a kind of plasma discharge, is generated. Active species with high oxidative decomposition power are generated when the discharge is generated.

  The discharge streamer guide portion 13 b introduces the active species generated by the discharge streamer body 13 a into the vertical wind passage member 330.

  The flow of air flowing into and out of the streamer discharge unit 13 is as follows. A tributary 502 (see FIG. 7) that is a part of the air blown from the sirocco fan 50 is sent to the streamer discharge unit 13. When this tributary 502 passes through the discharge streamer body 13a, active species are supplied by streamer discharge. The tributaries 502 supplied with active species are introduced into two vertical wind passage members 330 shown in FIG. The air containing the active species that has flowed into the vertical wind passage member 330 passes through the discharge port 331 and is blown out before the pre-filter 21 of the filter unit 20 as a plurality of diversions. The plurality of branch flows join the indoor air sucked from the pre-filter 21 and reach the dust collection filter 23 and the deodorization filter 25. At this time, the active species decomposes and purifies dust and bacteria adsorbed on the dust collection filter 23.

(2-5) Dehumidifying frame 33, rear frame 47
The dehumidifying frame 33 is provided at the rear portion of the front frame 30. The dehumidifying frame 33 accommodates the refrigeration cycle unit 60 on the front panel 100b side that is the front surface. That is, the refrigeration cycle unit 60 is disposed between the front frame 30 and the dehumidifying frame 33.

  The dehumidifying frame 33 accommodates the humidifying unit 40 and the water tank 71 on the rear panel 100c side that is the rear surface. Further, the dehumidifying frame 33 accommodates a dehumidifying tank unit 80 for storing water condensed during the dehumidifying operation on the bottom surface.

The air humidified by the humidifying member 41 is sent to the sirocco fan 50 side through the opening of the fan bell mouth 47a.

(2-6) Sirocco fan 50
The sirocco fan 50 generates an air flow 502 (see FIG. 7) that flows into the dehumidifying / humidifying device 100 and flows out of the dehumidifying / humidifying device 100. The sirocco fan 50 mainly includes a fan rotor 51, a scroll casing 53 that houses the fan rotor 51, and a fan motor 55.

  The fan rotor 51 is connected to a fan motor 55 disposed on the rear side of the fan rotor 51, and rotates when the fan motor 55 is driven. When the fan motor 55 is driven, the fan rotor 51 sucks air from the direction in which the rotating shaft extends and blows it out in the radial direction.

  The fan motor 55 can switch its rotational speed in stages. The rotational speed of the fan motor 55 is switched to the maximum output in the maximum air volume mode and switched to the minimum output in the minimum air volume mode.

  The scroll casing 53 is a synthetic resin casing member having a scroll bending portion in which the fan rotor 51 is accommodated. The scroll casing 53 is fixed to the rear portion of the rear frame 47.

  On the front side of the scroll casing 53, an opening having the same area as the fan rotor 51 as viewed from the front direction is formed, and the opening functions as the inlet 50 a of the sirocco fan 50. Further, an opening is formed in the upper portion of the scroll casing 53, and the opening functions as an outlet 50 b of the sirocco fan 50. The outlet 50b is connected to the outlet 115, and when the outlet 115 is exposed, the outlet 50b is also exposed.

The discharge channel 53b communicates with the scroll channel 53a and extends to the discharge port 50b. Therefore, the air guided to the discharge channel 53b is discharged from the discharge port 50b.

  When the sirocco fan 50 configured in such a manner is driven, the indoor air is taken into the dehumidifying / humidifying device 100 from the lower suction port 111 and the side suction port 113 and blown out from the blower outlet 115 to the room. Is returned.

(2-7) Refrigeration cycle unit 60
Next, the refrigeration cycle unit 60 will be described with reference to FIGS. FIG. 6 is a piping system diagram of the refrigeration cycle unit 60.

  As shown in FIG. 2, the refrigeration cycle unit 60 mainly includes an evaporator 61, a radiator 63, a capillary tube 65, and a compressor 67. The refrigeration cycle functions mainly by driving the evaporator 61, the radiator 63, the capillary tube 65, and the compressor 67. Furthermore, the refrigeration cycle unit 60 includes a compressor accumulator 69, a discharge pipe thermistor 62, and an antifreezing thermistor 64 as shown in FIG.

  The evaporator 61, the radiator 63, the capillary tube 65, and the compressor 67 are connected by a refrigerant pipe 120 as shown in FIG. A refrigerant circulates in the evaporator 61, the radiator 63, the capillary tube 65, the compressor 67 and the refrigerant pipe 120. The refrigerant pipe 120 includes a refrigerant pipe 120 a that connects the compressor 67 and the radiator 63, a refrigerant pipe 120 b that connects the radiator 63 and the evaporator 61, and a refrigerant pipe that connects the evaporator 61 and the compressor 67. 120c.

The compressor 67 compresses the refrigerant. The compressed refrigerant is supplied to the radiator 63 through the refrigerant pipe 120a. The radiator 63 condenses and liquefies the refrigerant. At this time, the radiator 63 radiates heat around the radiator 63. The refrigerant liquefied through the radiator 63 expands by passing through the capillary tube 65 provided in the refrigerant pipe 120b, and becomes a low-temperature and low-pressure refrigerant. Thereafter, the low-temperature and low-pressure refrigerant is introduced into the evaporator 61 through the refrigerant pipe 120b. The evaporator 61 evaporates the refrigerant and absorbs heat around the evaporator 61 to condense moisture in the air. That is, the evaporator 61 cools the air below the dew point during the dehumidifying operation. Thereafter, the refrigerant evaporated through the evaporator 61 returns to the compressor 67 via the refrigerant pipe 120 c and the compressor accumulator 69. As the refrigerant, various refrigerants such as R134a and CO ₂ can be applied.

  The refrigerant pipe 120 extending from the compressor 67 to the radiator 63 is particularly referred to as a discharge pipe 120a.

  The compressor accumulator 69 is a member for preventing the refrigerant that has not been vaporized by the evaporator 61 from being mixed into the compressor 67 in a liquid state. The discharge pipe thermistor 62 is a member for measuring the temperature of the discharge pipe 120a. The freeze prevention thermistor 64 is a member for measuring the temperature of the evaporator 61.

  The refrigeration cycle unit 60 including the evaporator 61, the radiator 63, and the compressor 67 is driven during the dehumidifying operation, thereby functioning as a dehumidifying device. In the present embodiment, the refrigeration cycle unit 60, which is this dehumidifying device, is used during the humidifying operation to improve the humidifying capacity. This point will be described in detail later.

  As shown in FIGS. 3 to 5, the evaporator 61, the radiator 63, the humidifying member 41, the fan bell mouth 47 a, the fan rotor 51, and the fan motor 55 are arranged in this order from the upstream side to the downstream side of the air flow. ing. The sirocco fan 50 including the fan rotor 51 and the fan motor 55 takes indoor air into the dehumidifying / humidifying device 100 and guides the taken air to the upper portion of the dehumidifying / humidifying device 100.

  In the present embodiment, the area of the evaporator 61 in the front direction is formed smaller than the radiator 63. For this reason, the evaporator 61 and the radiator 63 are not partially overlapped when viewed from the front side. Specifically, the radiator 63 is higher in the vertical direction than the evaporator 61. Therefore, when the evaporator 61 and the radiator 63 are arranged substantially at the lower part, the evaporator 61 is superimposed on the lower part of the radiator 63, but not on the upper part of the radiator 63.

  The humidifying member 41 is disposed behind the radiator 63 as shown in FIGS. As shown in FIGS. 3 to 5 and the like, the evaporator 61, the radiator 63, and the humidifying member 41 are arranged in order, so that only the air passing through the evaporator 61 and the radiator 63 and the upper part of the radiator 63 pass. The humidified air is supplied to the humidifying member 41. Further, when the radiator 63 and the radiator 63 and the humidifying member 41 do not overlap, the air that has not passed through the evaporator 61 and the radiator 63 is supplied to the humidifying member 41.

(2-8) Humidification unit 40, water tank 71
As shown in FIG. 2, the humidification unit 40 includes a humidification member 41 and a storage case 43. The humidifying member 41 has a structure in which, for example, a vaporization filter 41b is attached to a ring-shaped frame 41a. During the humidifying operation, the water is vaporized from the vaporizing filter 41b of the humidifying member 41, whereby humidification is performed. The humidifying member 41 is rotated by a motor. As the humidifying member 41 rotates, water is drawn up by ladle-shaped components attached to the ring-shaped frame and supplied to the dry vaporization filter as it rotates. Further, in order to assist water supply to the vaporization filter 41b, water is supplied to the vaporization filter 41b on the inner periphery of the ring-shaped frame 41a through the hole of the ring-shaped frame 41a. The water tank 71 is a tank for supplying water to the storage case 43.

  The air that has passed through the deodorizing filter 25 passes through the humidifying member 41 of the humidifying unit 40. When air passes through the humidifying member 41, moisture is released from the humidifying member 41 into the air.

(2-9) Dehumidification tank unit 80
As shown in FIG. 2, the dehumidifying tank unit 80 includes a dehumidifying tank 81 and a lid 83. The dehumidifying tank 81 stores the water condensed by the evaporator 61. The upper part of the dehumidifying tank 81 is covered with a lid 83. An opening 83 a is provided in the approximate center of the lid 83. The water condensed by the evaporator 61 is collected on the lid portion 83 and stored in the dehumidifying tank 81 through the opening 83a.

The air sucked from the first side suction port 113a and the second side suction port 113b reaches the discharge unit 11 (the first discharge unit 11a and the second discharge unit 11b). When passing through the discharge unit 11, dust or the like contained in the air is positively charged. Next, the air reaches the filter unit 20. On the other hand, the air sucked from the lower suction port 111 reaches the filter unit 20.

  In the filter unit 20, the air first passes through the prefilter 21. At that time, relatively large dust and dust are removed from the air by the pre-filter 21.

  The air that has passed through the dust collection filter 23 passes through the deodorization filter 25 and is deodorized at this time.

  Part of the air that has passed through the deodorizing filter 25 passes through the evaporator 61. During the dehumidifying operation, moisture in the air is condensed by the passage of the evaporator 61 to perform dehumidification. The air that has passed through the evaporator 61 passes through the radiator 63 that constitutes a part of the refrigeration cycle together with the evaporator 61.

  Thereafter, the air reaches the humidifying member 41 of the humidifying unit 40. During the humidifying operation, the air passes through the humidifying member 41, whereby the moisture contained in the humidifying member 41 is released into the air and humidified.

  The air that has passed through the filter unit 20 and the humidifying member 41 and has been purified is blown out from the air outlet 115 into the room. A part of the purified air is introduced into the streamer discharge unit 13 as a tributary 502 without being blown into the room.

  Active species are generated by the streamer discharge in the discharge streamer body 13a of the streamer discharge unit 13. The tributary 502 becomes air containing active species by passing through the streamer discharge unit 13. The air containing the active species passes through the two vertical ventilation path members 330 and is discharged before the pre-filter 21 from a plurality of discharge ports 331 formed in each vertical ventilation path member 330. The air containing the active species is mixed with the suction air and sucked into the prefilter 21 and the dust collection filter 23. Air containing these active species inactivates or kills viruses, fungi, bacteria, and the like.

(4) Functional Configuration Next, a functional configuration of the dehumidifying / humidifying device 100 according to the present embodiment will be described. FIG. 8 is a block diagram showing a functional configuration of the dehumidifying / humidifying device 100.

  The dehumidifying / humidifying device 100 includes a CPU 250, a RAM 251 and the like as hardware configured by various circuit components housed in the electrical component unit 90. The dehumidifying / humidifying device 100 includes a control unit 250a embodied by the CPU 250 and a predetermined condition storage unit 251a embodied by the RAM 251 or the like as functional units.

  When the user operates the various operation switches 101 and the operation display unit 102 of the operation panel cover 100f-2, operation information is transmitted to various circuit components of the electrical component unit 90. The CPU 250 composed of various circuit components performs an operation according to a user operation in cooperation with the RAM 251 and the like.

  The predetermined condition storage unit 251a stores predetermined conditions such as a start condition and a stop condition for the humidifying operation and the dehumidifying operation. For example, the predetermined condition includes a condition for operating the compressor 67 only in the initial stage of the humidifying operation. Examples of the predetermined condition include a predetermined condition indicating an increase in humidity. Specifically, the predetermined condition includes, for example, at least one of predetermined humidity, elapsed time from the start of the humidification operation, and the temperature of the evaporator 61.

  The control unit 250a refers to predetermined conditions in the predetermined condition storage unit 251a and controls operations including dehumidifying operation and humidifying operation.

(5) Configuration for improving humidification capability (5-1) Arrangement configuration In the present embodiment, in order to improve the humidification capability, a radiator is used so that air that has passed through the radiator 63 passes through the humidification member 41. 63 and the humidifying member 41 are arranged. This configuration will be described more specifically below.

  FIG. 9 is a schematic diagram of a side cross-section of the dehumidifying / humidifying device 100. As shown in FIG. 9, the filter unit 20, the evaporator 61, the radiator 63, and the humidifying member 41 are sequentially arranged from the front side of the dehumidifying / humidifying device 100, that is, from the upstream side to the downstream side of the air flow. Yes. A fan bell mouth 47a, a fan rotor 51, a fan motor 55, and the like are disposed at the rear of the humidifying member 41. Air is taken in from the outside of the dehumidifying / humidifying device 100 through the filter unit 20 by driving the fan rotor 51 and the fan motor 55. Thereafter, the air taken in from the filter unit 20 passes through the evaporator 61, the radiator 63, and the humidifying member 41, and is discharged to the outside of the dehumidifying / humidifying device 100 through the air outlet 115.

  During the dehumidifying operation, the control unit 250a uses the function of driving the refrigeration cycle unit 60 including the evaporator 61, the radiator 63, the compressor 67, and the like, and condensing moisture in the air of the evaporator 61. In the present embodiment, the controller 250a drives the refrigeration cycle unit 60 even during the humidifying operation. The radiator 63 condenses and liquefies the refrigerant. At this time, the radiator 63 radiates heat around the radiator 63. Here, as described above, the radiator 63 and the humidifying member 41 are arranged such that the sucked air flows from the radiator 63 toward the humidifying member 41. That is, the radiator 63 and the humidifying member 41 are sequentially arranged from the upstream side to the downstream side of the intake air. For this reason, the air from the radiator 63 toward the humidifying member 41 is warmed by the heat released from the radiator 63. Therefore, warmed air is supplied to the humidifying member 41. As a result, the amount of water released from the humidifying member 41 is increased and the humidifying ability is improved.

  In addition, when the air warmed by the radiator 63 is supplied to the humidifying member 41 after the humidifying operation is completed, the drying speed of the humidifying member 41 can be increased. Therefore, it is possible to suppress bacteria, mold, and the like that are generated when the humidifying member 41 contains moisture.

(5-2) Air to be supplied to the humidifying member 41 In particular, in FIGS. 4, 5, and 9, the evaporator 61, the radiator 63, and the humidifying member 41 are arranged from the upstream side to the downstream side of the intake air. Are arranged in order. Further, as described above, the upper portion of the radiator 63 does not overlap the evaporator 61. In this case, the air supplied to the humidifying member 41 has the following flow.

  FIG. 10 is a schematic diagram showing the flow of air supplied to the humidifying member 41 via the evaporator 61 and the radiator 63. The air A1 in front of the evaporator 61 is cooled by passing through the evaporator 61 to become air A2. The cooled air A2 is warmed by the radiator 63 to become air A3. On the other hand, the air B1 that does not pass through the evaporator 61 is heated by the radiator 63 to become air B2. Since the air B2 does not pass through the evaporator 61 and is not cooled, the temperature becomes higher than that of the air A3. Therefore, since the higher temperature air B2 can be supplied to the humidifying member 41, the amount of water released is increased and the humidifying ability can be increased. In addition, since the air A2 cooled by the evaporator 61 cools the radiator 63, the heat radiation efficiency of the radiator 63 can be improved. As a result, the temperature of the air B2 and the air A3 can be increased, and high-temperature air can be supplied to the humidifying member 41 to improve the humidifying capacity.

(6) Control at the time of humidification operation The control part 250a drives the compressor 67 only in the initial stage at the time of humidification operation. In the initial stage of the humidifying operation, it is desired to humidify earlier because the humidity is low. By operating the compressor 67 and driving the refrigeration cycle unit 60 in the initial stage of the humidification operation, the air heated by the heat radiation from the radiator 63 is supplied to the humidification member 41. When the humidification operation is continued, the humidity rises and reaches a predetermined humidity. When the operation of the compressor 67 is further continued, dehumidification is performed by the evaporator 61. Therefore, the control unit 250a controls to operate the compressor 67 only in the initial stage of the humidifying operation. Thereby, the inefficient driving | operation of the compressor 67 in which humidification and dehumidification are performed in parallel can be suppressed.

  More specifically, the controller 250a stops the compressor 67 based on a predetermined condition indicating an increase in humidity during the humidifying operation. The predetermined condition storage unit 251a stores predetermined conditions. The predetermined condition indicating the increase in humidity includes at least one of the predetermined humidity, the elapsed time from the start of the humidifying operation, and the temperature of the evaporator 61. In addition, for example, it is possible to grasp an increase in humidity by detecting a predetermined humidity, an elapsed time from the start of the humidifying operation, a temperature of the evaporator, and the like with a timer and various sensors. If the operation of the compressor 67 is continued even after the humidity rises to some extent, the evaporator 61 performs dehumidification. Therefore, the controller 250a stops the compressor 67 when the humidity increases during the humidifying operation, and suppresses the inefficient operation of the compressor 67.

(7) Features The features of the above embodiment can be described as follows.

(7-1)
The dehumidifying / humidifying device 100 includes a sirocco fan 50, a refrigeration cycle unit 60, a humidifying member 41, and a controller 250a. The sirocco fan 50 sucks air and blows it out into the room. The refrigeration cycle unit 60 includes an evaporator 61 and a radiator 63 that cool the sucked air below the dew point during the dehumidifying operation. The humidifying member 41 temporarily holds the water supplied during the humidifying operation and releases the water into the air. The controller 250a controls operations including a dehumidifying operation and a humidifying operation. Here, the radiator 63 and the humidifying member 41 are arranged so that the air that has passed through the radiator 63 passes through the humidifying member 41. The controller 250 a operates the refrigeration cycle unit 60 during the humidifying operation, so that the air heated through the radiator 63 passes through the humidifying member 41.

  The radiator 63 and the humidifying member 41 are arranged so that the sucked air flows from the radiator 63 toward the humidifying member 41. That is, the radiator 63 and the humidifying member 41 are sequentially arranged from the upstream side to the downstream side of the intake air. Here, the radiator 63 releases heat by operating the refrigeration cycle unit 60 during the humidification operation. This released heat warms the air from the radiator 63 toward the humidifying member 41. Therefore, warmed air is supplied to the humidifying member 41. Therefore, the amount of water released from the humidifying member 41 is increased, and the humidifying ability is improved.

  In addition, when the air warmed by the radiator 63 is supplied to the humidifying member 41 after the humidifying operation is completed, the drying speed of the humidifying member 41 can be increased. Therefore, it is possible to suppress bacteria, mold, and the like that are generated when the humidifying member 41 contains moisture.

  Note that it is only necessary that the radiator 63 and the humidifying member 41 are arranged so as to overlap in order along the flow direction of the intake air. For example, the evaporator 61 and the radiator 63 are not necessarily arranged so as to overlap each other when viewed from the flow direction of the intake air. However, the evaporator 61 and the radiator 63 may overlap each other when viewed from the flow direction of the intake air. In this case, since the air cooled by the evaporator 61 cools the radiator 63, the heat dissipation efficiency of the radiator 63 is improved.

(7-2)
An evaporator 61 and a radiator 63 are arranged from the upstream side to the downstream side of the intake air. Further, a part of the radiator 63 does not overlap the evaporator 61 when viewed from the flow direction of the intake air.

  As described above, a part of the radiator 63 does not overlap with the evaporator 61. Therefore, a part of the sucked air does not pass through the evaporator 61 but passes through only a part of the radiator 63 and is supplied to the humidifying member 41. That is, a part of the sucked air is supplied to a part of the radiator 63 without being absorbed by the evaporator 61. Accordingly, a part of the sucked air is warmed by the radiator 63 without the temperature being lowered by the evaporator 61, so that higher temperature air can be supplied to the humidifying member 41. Therefore, the humidifying ability in the humidifying member 41 can be further improved.

(7-3)
The radiator 63 is supplied with refrigerant from a part of the radiator 63 that does not overlap the evaporator 61.

  Here, a high-temperature refrigerant is supplied to the radiator 63. This high-temperature refrigerant is supplied from a portion not overlapping with the evaporator 61. In a portion of the radiator 63 that does not overlap with the evaporator 61, the suction air is supplied without passing through the evaporator 61. Therefore, the air passing through a portion of the radiator 63 that does not overlap with the evaporator 61 is not lowered by the passage of the evaporator 61 and is warmed by the high-temperature refrigerant. Therefore, higher-temperature air can be supplied to the humidifying member 41, and the humidifying ability of the humidifying member 41 can be further improved.

  For example, it is assumed that the upper portion of the radiator 63 does not overlap the evaporator 61 when viewed from the flow direction of the intake air. In this case, a high-temperature refrigerant is supplied from the upper part of the radiator 63. The air passing through the upper part of the radiator 63 does not pass through the evaporator 61, so the temperature does not decrease and is warmed by the high-temperature refrigerant. For this reason, the humidifying ability of the humidifying member 41 can be further improved.

(7-4)
The refrigeration cycle unit 60 further includes a compressor 67 connected to the evaporator 61 and the radiator 63. The controller 250a operates the compressor 67 only in the initial stage of the humidifying operation.

  Here, since the humidity is low at the initial stage of the humidifying operation, it is desired to humidify earlier. By operating the compressor 67 and driving the refrigeration cycle in the initial stage of the humidifying operation, the air heated by the heat radiation from the radiator 63 is supplied to the humidifying member 41. When the humidification operation is continued, the humidity rises and reaches a predetermined humidity. When the operation of the compressor 67 is further continued, dehumidification is performed by the evaporator 61. Therefore, the control unit 250a controls to operate the compressor 67 only in the initial stage of the humidifying operation. Thereby, the inefficient driving | operation of the compressor 67 in which humidification and dehumidification are performed in parallel can be suppressed.

(7-5)
The controller 250a stops the compressor 67 based on a predetermined condition indicating an increase in humidity during the humidifying operation.

  If the operation of the compressor 67 is continued even after the humidity rises to some extent, the evaporator 61 performs dehumidification. Therefore, the controller 250a stops the compressor 67 when the humidity increases during the humidifying operation, and suppresses the inefficient operation of the compressor 67.

(7-6)
The predetermined condition includes at least one of a predetermined humidity, an elapsed time from the start of the humidification operation, and a temperature of the evaporator 61.

  For example, it is possible to grasp an increase in humidity by detecting that the predetermined humidity has been reached, the elapsed time from the start of the humidifying operation, the temperature of the evaporator 61, and the like with a timer and various sensors.

(8) Modification (8-1) Modification 1A
In the said embodiment, it does not specifically limit about the method of supply of the refrigerant | coolant to the heat radiator 63. FIG. As shown in FIGS. 4, 5, and 9, the evaporator 61, the radiator 63, and the humidifying member 41 are sequentially arranged. Further, the radiator 63 is higher in the vertical direction than the evaporator 61. Therefore, when the evaporator 61 and the radiator 63 are arranged substantially at the lower part, the evaporator 61 is superimposed on the lower part of the radiator 63, but not on the upper part of the radiator 63.

  In such a configuration, the refrigerant is supplied to the radiator 63 from a part of the radiator 63 that does not overlap with the evaporator 61. FIG. 11 is a schematic diagram showing refrigerant piping of the radiator 63. As shown by the arrows in FIG. 11, the refrigerant is supplied to the radiator 63 from the upper portion not overlapping with the evaporator 61. Therefore, the temperature of the refrigerant in the upper part of the radiator 63 is higher than that in the lower part. At this time, as shown in FIG. 10 described above, the air B1 that has not passed through the evaporator 61 is supplied to the upper portion of the radiator 63 that does not overlap the evaporator 61. Therefore, the air B <b> 1 does not decrease in temperature due to the passage of the evaporator 61 and is warmed by the higher-temperature refrigerant supplied from the upper part of the radiator 63. Therefore, higher-temperature air can be supplied to the humidifying member 41, and the humidifying ability of the humidifying member 41 can be further improved.

  In the present modification, since the radiator 63 does not overlap the evaporator 61 at the upper part, the refrigerant is supplied from the upper part of the radiator 63. Since it is only necessary to supply the refrigerant from a portion where the radiator 63 does not overlap the evaporator 61, the supply location of the refrigerant in the radiator 63 is not limited to the upper part. For example, it is assumed that the lower part of the radiator 63 does not overlap the evaporator 61 when viewed from the flow direction of the intake air. In this case, a high-temperature refrigerant is supplied from the lower part of the radiator 63. The air passing through the lower part of the radiator 63 does not pass through the evaporator 61, so the temperature does not decrease and is warmed by the high-temperature refrigerant. Therefore, higher-temperature air can be supplied to the humidifying member 41, and the humidifying ability of the humidifying member 41 can be further improved.

(8-2) Modification 1B
(8-2-1) Configuration of Modification 1B In the above embodiment, the amount of refrigerant supplied to the evaporator 61 is not adjusted. The amount of dehumidification in the evaporator 61 may be adjusted by adjusting the amount of refrigerant supplied to the evaporator 61. Such a configuration will be described below. FIG. 12 is another piping system diagram of the refrigeration cycle unit 60. The refrigeration cycle unit 60 of FIG. 12 further includes a hot gas bypass valve 150, unlike FIG. 6 of the above embodiment. Other configurations are the same as those in FIG.

  As shown in FIG. 12, the refrigeration cycle unit 60 includes an evaporator 61, a radiator 63, a capillary tube 65, a compressor 67, a compressor accumulator 69, a hot gas bypass valve 150, a discharge pipe thermistor 62, and an antifreezing thermistor 64. Including. The hot gas bypass valve 150 is provided in a path connecting the compressor 67 and the evaporator 61. The hot gas bypass valve 150 is a valve for adjusting the amount of refrigerant from the compressor 67 toward the evaporator 61. The controller 250a of the dehumidifying / humidifying device 100 adjusts the opening degree of the hot gas bypass valve 150. Thereby, the temperature of the evaporator 61 is adjusted and the dehumidification amount in the evaporator 61 is controlled.

  In the above embodiment, the air supplied to the humidifying member 41 is warmed by the radiator 63 during the humidifying operation. Thereby, the humidification capability in the dehumidifying / humidifying device 100 can be improved. On the other hand, the evaporator 61 has a dehumidifying function, which may reduce the humidification ability. Therefore, the control unit 250a increases the opening degree of the hot gas bypass valve 150 when suppressing the dehumidifying function during the humidifying operation. Thereby, the high-temperature refrigerant from the compressor 67 is supplied to the evaporator 61, and the temperature of the evaporator 61 rises. Therefore, the dew condensation start point in the evaporator 61 is shifted backward, and dehumidification in the evaporator 61 can be suppressed. That is, the start of condensation is delayed. As a result, it is possible to suppress a decrease in the humidifying ability and further improve the dehumidifying ability in the dehumidifying / humidifying device 100 in the above embodiment.

(8-2-2) Features The features of Modification 1B can be described as follows.

  The dehumidifying / humidifying device 100 includes a sirocco fan 50, a refrigeration cycle unit 60, a humidifying member 41, and a controller 250a. The sirocco fan 50 sucks air and blows it out into the room. The refrigeration cycle unit 60 includes an evaporator 61 and a radiator 63 that cool the sucked air below the dew point during the dehumidifying operation. The humidifying member 41 temporarily holds the water supplied during the humidifying operation and releases the water into the air. The controller 250a controls operations including a dehumidifying operation and a humidifying operation.

  Here, the refrigeration cycle unit 60 further includes a compressor 67 and a hot gas bypass valve 150. The compressor 67 is connected to the evaporator 61 and the radiator 63. The hot gas bypass valve 150 is provided in a path connecting the compressor 67 and the evaporator 61. The controller 250a adjusts the temperature of the evaporator 61 by adjusting the opening degree of the hot gas bypass valve 150 during the humidifying operation, and suppresses dehumidification in the evaporator 61.

  With such a configuration, it is possible to obtain the effects described in Modification 1B.

(8-3) Modification 1C
(8-3-1) Configuration of Modification 1C In the above embodiment, the amount of refrigerant supplied to the evaporator 61 is not adjusted. The amount of dehumidification in the evaporator 61 may be adjusted by adjusting the amount of refrigerant supplied to the evaporator 61. Another modified example of such a configuration will be described below.

  FIG. 13 is another piping system diagram of the refrigeration cycle unit 60. The refrigeration cycle unit 60 of FIG. 13 includes an electric valve 160 instead of the capillary tube 65, unlike FIG. 6 of the above embodiment. Other configurations are the same as those in FIG.

  As shown in FIG. 13, the refrigeration cycle unit 60 includes an evaporator 61, a radiator 63, a compressor 67, a compressor accumulator 69, an electric valve 160, a discharge pipe thermistor 62, and an antifreeze thermistor 64. The motorized valve 160 is provided between the evaporator 61 and the radiator 63. The motorized valve 160 is a valve for adjusting the amount of refrigerant from the radiator 63 toward the evaporator 61. The control unit 250a of the dehumidifying / humidifying device 100 adjusts the opening degree of the electric valve 160. Thereby, the temperature of the evaporator 61 is adjusted and the dehumidification amount in the evaporator 61 is controlled.

  In the above embodiment, the air supplied to the humidifying member 41 is warmed by the radiator 63 during the humidifying operation. Thereby, the humidification capability in the dehumidifying / humidifying device 100 can be improved. On the other hand, the evaporator 61 has a dehumidifying function, which may reduce the humidification ability. Therefore, the controller 250a adjusts the opening degree of the motor-operated valve 160 provided between the evaporator 61 and the radiator 63 during the humidifying operation. Thereby, the warm refrigerant | coolant from the heat radiator 63 is supplied to the evaporator 61, and the temperature of the evaporator 61 rises. Therefore, the dew condensation start point in the evaporator 61 is shifted backward, and dehumidification in the evaporator 61 can be suppressed. As a result, it is possible to suppress a decrease in the humidifying ability and further improve the dehumidifying ability in the dehumidifying / humidifying device 100 in the above embodiment.

(8-3-2) Features The dehumidifying / humidifying device 100 includes a sirocco fan 50, a refrigeration cycle unit 60, a humidifying member 41, and a controller 250a. The sirocco fan 50 sucks air and blows it out into the room. The refrigeration cycle unit 60 includes an evaporator 61 and a radiator 63 that cool the sucked air below the dew point during the dehumidifying operation. The humidifying member 41 temporarily holds the water supplied during the humidifying operation and releases the water into the air. The controller 250a controls operations including a dehumidifying operation and a humidifying operation.

  Here, the refrigeration cycle unit 60 further includes an electric valve 160. The motorized valve 160 is provided between the evaporator 61 and the radiator 63. The controller 250a adjusts the temperature of the evaporator 61 by adjusting the opening degree of the motor-operated valve 160 during the humidification operation, and suppresses dehumidification in the evaporator 61.

  With such a configuration, the operational effects described in Modification 1C can be obtained.

(8-4) Modification 1D
In the said embodiment, as shown in FIG.4, FIG5 and FIG.9 etc., the evaporator 61, the heat radiator 63, and the humidification member 41 are arrange | positioned in order from the upstream of the suction air to the downstream. However, the radiator 63 and the humidification member 41 should just be arrange | positioned along with the flow direction of suction air so that it may overlap in order. Therefore, for example, the evaporator 61 and the radiator 63 are not necessarily arranged so as to overlap each other when viewed from the flow direction of the intake air, and the evaporator 61 and the radiator 63 may be arranged in the vertical direction. . Such a configuration will be described below.

  FIG. 14 is a schematic diagram illustrating another arrangement configuration of the evaporator 61, the radiator 63, and the humidifying member 41. FIG. 15 is a schematic diagram showing the flow of air supplied to the humidifying member 41 via the evaporator 61 and the radiator 63. Unlike the structure of the said embodiment of FIG. 9, the evaporator 61 and the heat radiator 63 are arrange | positioned up and down. Specifically, the evaporator 61 is disposed below the radiator 63, and the radiator 63 is disposed on the upstream side of the air flow of the humidifying member 41.

  When the sirocco fan 50 is driven by driving the fan motor 55, air is taken in from the outside of the dehumidifying / humidifying device 100 through the filter unit 20. The taken air passes through the radiator 63 and is supplied to the humidifying member 41. Then, it discharge | releases outside from the blower outlet 115 of the dehumidification / humidification apparatus 100 upper part. More specifically, as shown in FIG. 15, the air A1 on the front surface of the evaporator 61 is cooled by the passage of the evaporator 61 to become air A2. On the other hand, the air B1 that does not pass through the evaporator 61 is heated by the radiator 63 to become air B2. Since the air B2 does not pass through the evaporator 61 and is not cooled, the temperature becomes higher than that of the air A2. Therefore, since the higher temperature air B2 can be supplied to the humidifying member 41, the amount of water released from the humidifying member 41 is increased, and the humidifying ability can be enhanced.

(8-5) Modification 1E
In the embodiment and the modified example, the plane area of the radiator 63 is formed larger than the plane area of the evaporator 61. However, it is sufficient that the air supplied to the humidifying member 41 can be warmed by the heat released from the radiator 63, and the plane area of the radiator 63 and the plane area of the evaporator 61 are not particularly limited. However, as described above, when the plane area of the radiator 63 is larger than the plane area of the evaporator 61, high-temperature air that has passed only through the radiator 63 can be supplied to the humidifying member 41.

  The present invention is applicable to various dehumidifying / humidifying devices having dehumidifying and humidifying functions.
