The blower 2 includes a multiblade fan 21, a fan case 22, a fan motor 23, and a discharge port 24. Here, the multiblade fan 21 is a fan that discharges air in the centrifugal direction, and rotates to suck air from the central portion and generate an airflow toward the outer periphery. The multi-blade fan 21 is a so-called double-blade fan having a configuration in which the blades are arranged side by side in the axial direction and having a configuration capable of sucking air from the central portions at both ends in the axial direction. Moreover, in FIG. 4, although the air blower 2 inclines so that an upper part may approach a back side, you may be provided so that it may not incline.

The discharge port 24 is an opening that discharges airflow generated by the rotation of the multiblade fan 21. The discharge port 24 has a cylindrical shape communicating with the inside of the fan case 22 where the multiblade fan 21 is disposed. The discharge port 24 communicates with the blowout port 15. That is, the airflow discharged from the discharge port 24 is blown out of the dehumidifying / humidifying device A through the blowout port 15. In addition, by forming the blowout port 15 so as to have a certain length in the flow direction of the airflow, the blown airflow can be rectified, and the airflow can be dispersed far away. Although not shown, an ion generator may be disposed at the outlet 15 so that ions are included in the airflow as necessary.

The air cleaning unit 3 includes an air cleaning filter 31 and a mesh 32. The air cleaning unit 3 is disposed in an opening 111 provided on the back surface of the case 11. The mesh 32 is a mesh-like member, is a protective member for suppressing the intrusion of hands, tools, and the like from the opening 111, and is used as a holder for holding the air purifying filter 31 so as not to be displaced. Is done. The air cleaning filter 31 is a filter that collects foreign matters such as dust and dust from the passing air. The air purifying filter 31 and the mesh 32 are detachably attached to the opening 111.

The air purification filter 31 may include a nonwoven fabric filter, but is not limited thereto. As the amount of air passing through the air cleaning filter 31 increases, that is, as the flow rate of the air flow increases, the foreign matter collection efficiency increases. Moreover, the air purification filter 31 becomes difficult to pass air, when the quantity of the collected foreign material increases. Therefore, it is configured to be removable only by removing the rear cover 13. The air cleaning filter 31 may be disposable or reused after cleaning. All of the first suction port 16 and the second suction port 17 may be covered with one air purification filter 31 or may be divided and covered.

The dehumidifying unit 4 includes an evaporator 41, a condenser 42, a dehumidifying tray 43, and a dehumidifying tank 44. The dehumidification unit 4 removes the moisture contained in the air, that is, dehumidifies it by cooling the air passing therethrough and condensing the moisture contained in the air. The dehumidifying unit 4 includes a refrigeration cycle device that circulates the refrigerant and cools the air by utilizing the phase change of the refrigerant. In addition to the evaporator 41 and the condenser 42, the refrigeration cycle apparatus includes a compressor, an expander, etc. (not shown).

The evaporator 41 and the condenser 42 are heat exchangers, and examples thereof include, but are not limited to, heat exchangers using fins. The dehumidifying unit 4 is provided on the front side with respect to the blower 2 of the case 11 and is disposed in the vicinity of the second air inlet 26. When air is sucked into the fan case 22 from the second air inlet 26 by driving the blower 2, an airflow flowing through the gaps between the fins of the evaporator 41 and the condenser 42 is generated.

The evaporator 41 cools the air passing therethrough and causes condensation in the evaporator 41, here, mainly fins and pipes, to reduce the humidity in the air. Further, the condenser 42 warms the passing air. In the dehumidifying unit 4, an evaporator 41 is disposed on the upstream side of the airflow, and the air is cooled and dehumidified by condensation. Then, the air cooled by the evaporator 41 is heated by heat exchange with a high-temperature refrigerant by the condenser 42, and the temperature is raised to the same or substantially the same temperature as when the air flows into the evaporator 41. From the above, in the dehumidifying unit 4, the evaporator 41 is disposed upstream of the airflow condenser 42.

Further, the dehumidifying tray 43 is a container disposed at the lower portion of the evaporator 41, and is a tray for receiving condensed water condensed on the surface of the evaporator 41, so-called drain water. The water (drain water) received by the dehumidifying tray 43 is sent to the dehumidifying tank 44 via a pipe (not shown). The dehumidification tank 44 is a container that is slidably attached to the case 11 and is detachable. The dehumidification tank 44 can detect the amount of accumulated drain water, for example, the water level. In the dehumidifying / humidifying device A, when a certain amount of drain water accumulates in the dehumidifying tank 44, a warning is given and at least the dehumidifying unit 4 of the dehumidifying / humidifying device A stops. The user removes the dehumidifying tank 44 in response to the warning and drains the accumulated drain water, so that the user can use it again. In addition, since it is the structure in which air purification is possible, even if it removes the dehumidification tank 44, you may continue moving the fan 21 similarly to an air cleaning driving | operation.

In this embodiment, dehumidification is performed using a refrigeration cycle. However, the present invention is not limited to this, and a dehumidification unit using a material that adsorbs water such as a desiccant may be used.

The humidification unit 5 includes a humidification rotor 51, a drive motor 52, a humidification tray 53, a humidification member 54, and a humidification tank 55. As shown in FIG. 3 and the like, the humidification rotor 51 includes a cylindrical portion 511 provided on the outer peripheral portion and a support portion 512 that supports the inside of the cylindrical portion 511, and is rotatably supported by the case 11. . Inside the cylindrical part 511, the humidification member 54 which can contain water, ie, can hold | maintain water, is arrange | positioned. The cylindrical portion 511 and the support portion 512 serve as a holding member that holds the humidifying member 54.

The humidification rotor 51 is rotatably provided, and the humidification rotor 51 is rotated by an axial force output from the drive motor 52 via a power transmission mechanism (not shown). The humidification rotor 51 and the humidification tray 53 are arranged so that the lower part of the humidification rotor 51 passes through the inside of the humidification tray 53. The cylindrical portion 511 of the humidification rotor 51 is provided with a bucket capable of scooping up water, and when the humidification rotor 51 rotates, the water collected in the humidification tray 53 is scooped up by the bucket, and the humidification member is Pour water into 54. Thereby, water is supplied to the humidifying member 54. The humidifying member 54 includes a member having innumerable minute gaps such as a non-woven fabric, and water is spread throughout the capillarity. Note that the humidifying tray 53 and the humidifying tank 55 are connected by a pipe, and water is added from the humidifying tank 55 so that the humidifying tray 53 has a water amount equal to or greater than a certain amount.

The humidifying rotor 51 may be configured to rotate, and the plurality of humidifying members 54 may be held independently. Since the supply of water from the bucket can be stopped by stopping the rotation of the humidification rotor 51, the humidification member 54 can be easily dried. That is, when the humidifying function is switched to the air cleaning function or the dehumidifying function, the time during which high-humidity air flows can be shortened. The function after switching is not limited to the air cleaning function or the dehumidifying function.

The humidification unit 5 is provided in the case 11 on the back side with respect to the blower 2 and is disposed close to the first air inlet 25. In other words, the end of the humidifying rotor 51 of the humidifying unit 5 in the rotational axis direction is disposed so as to face the first intake port 25. When air is sucked into the fan case 22 from the first air inlet 25 by driving the blower 2, an airflow that flows in the axial direction inside the cylindrical portion 511 of the humidification rotor 51 is generated. A humidifying member 54 is disposed inside the cylindrical portion 511. When the humidifying member 54 holds water, that is, when it is wet, the humidifying member 54 supplies water to the airflow, that is, flows. Humidify the air. The position of the humidification unit 5 is adjusted so that the airflow flowing through the humidification rotor 51 passes through the humidification member 54 holding water during the humidification operation.

In the dehumidifying / humidifying device A, the humidifying unit 5 rotates the humidifying rotor 51 to scoop water with a bucket, and the scooped water flows from the top to the humidifying member 54, but is not limited thereto. For example, the humidification member 54 may come into contact with the water stored in the humidification tray 53 and spread by capillary action. Note that the humidifying tray 53 and / or the humidifying tank 55 may be provided with a function for suppressing deterioration of accumulated water, such as a sterilization function.

Next, the air path that is the path through which the air flow of the dehumidifying / humidifying device A according to the present invention flows will be described. FIG. 5 is a view showing an air path of the dehumidifying / humidifying device according to the present invention. In FIG. 5, the first air path and the second air path are described using arrows.

As shown in FIG. 5, in the dehumidifying / humidifying device A, the air that has passed through the air purification filter 31 is blown out from the first suction port 16 through the humidification unit 5, the first intake port 25, the fan case 22, and the discharge port 24. A first air passage R1 reaching the mouth 15 is formed. The first air path R <b> 1 includes a path through which air sucked from the first suction port 16 flows directly into the humidification unit 5 and passes through the first suction port 25 and flows into the fan case 22.

In addition, the second air that has passed through the air purifying filter 31 bypasses the blower 2 from the second suction port 17 and reaches the blowout port 15 through the dehumidifying unit 4, the second intake port 26, the fan case 22, and the discharge port 24. An air path R2 is formed. In the second air path R2, the air flowing in from the upper second suction port 17 passes through the upper part of the upper partition member 181, flows downward along the front cover 12, passes through the dehumidifying unit 4, and passes through the dehumidifying unit 4. 2 The upper air passage R21 flowing into the fan case 22 from the air inlet 26 is included. Further, in the second air passage R2, the air flowing in from the lower second suction port 17 passes through the lower part of the lower partition member 182, flows upward along the front cover 12, and passes through the dehumidifying unit 4. The lower air passage R22 that flows into the fan case 22 from the second air inlet 26 is included.

In the dehumidifying / humidifying device A, airflow is generated in the first air path R1 and the second air path R2 (R21 and R22) by the rotational drive of the multiblade fan 21 regardless of the operations of the dehumidifying unit 4 and the humidifying unit 5. The first suction port 16 that is the suction port of the first air passage R1 and the second suction port 17 of the second air passage R2 (R21, R22) are both covered with the air purifying filter 31, and the first suction port 16 The airflow passing through the second suction port 17 passes through the air cleaning filter 31.

And the dehumidifying / humidifying device A has a configuration capable of selectively operating the dehumidifying unit 4 or the humidifying unit 5. That is, both the dehumidifying unit 4 and the humidifying unit 5 are stopped, and only the dehumidifying unit 4 is switched to operation or only the humidifying unit 5 is switched to operation. The three types of operations will be described below.

When both the dehumidifying unit 4 and the humidifying unit 5 are stopped, an air cleaning operation for removing foreign matter by the air cleaning filter 31 of the air cleaning unit 3 is performed. In other words, the airflow generated in the first air path R1 passes through the humidification unit 5, but the humidification of the air that passes through the humidification unit 5 is not performed. Further, the airflow generated in the second air passage R2 (R21, R22) passes through the dehumidifying unit 4, but since the dehumidifying unit 4 is stopped, the passing air is not dehumidified. For this reason, the air sucked from the first suction port 16 and the second suction port 17 and blown from the blowout port 15 collects dust and the like but is not dehumidified or humidified.

When only the dehumidifying unit 4 is operated, the airflow flowing through the first air path R1 passes through the non-operating humidifying unit 5 and therefore is not humidified. Moreover, since the airflow which flows through 2nd wind path R2 (R21, R22) passes the dehumidifying unit 4 which is operate | moving, it dehumidifies. That is, in the dehumidifying operation in which the dehumidifying unit 4 is operated, foreign matter is collected from the airflow (air) by the air purifying filter 31, and the airflow flowing through the second air path R2 (R21, R22) is dehumidified. .

When only the humidifying unit 5 is operated, the airflow flowing through the second air path R2 (R21, R22) passes through the dehumidifying unit 4 that is not operating, and thus is not dehumidified. Moreover, since the airflow which flows through 1st wind path R1 passes the humidification unit 5 which is operate | moving, it is humidified. That is, in the humidifying operation in which the humidifying unit 5 is operated, the foreign substance is collected by the air cleaning filter 31 from the passing air and the air flow flowing through the first air path R1 is humidified.

As described above, the air cleaning operation, the dehumidifying operation and the humidifying operation are performed. Next, the first air path R1 and the second air path R2 will be described. The air cleaning unit 3, the dehumidifying unit 4 and the humidifying unit 5 perform different operations. The efficiency of each operation varies depending on the flow rate of the airflow. For example, in the air cleaning unit 3, the greater the airflow rate, the higher the efficiency of collecting foreign matter. On the other hand, the dehumidifying unit 4 dehumidifies by cooling the air flowing when the airflow passes through the evaporator 41 and generating condensation. Therefore, the airflow is preferably in contact with the evaporator 41 while being cooled to a temperature at which condensation occurs. On the other hand, if the contact is too long, the air flow after condensation has been kept in contact with the evaporator 41, and the efficiency is poor. That is, in the dehumidifying unit 4, there is a flow rate or flow rate at which the dehumidifying efficiency is highest. Similarly, the humidifying unit 5 imparts moisture to the airflow when passing through the wet humidifying member 54, and therefore there is a flow rate or flow rate at which the humidification efficiency is highest.

In the dehumidifying / humidifying device A, an air flow is generated in the first air passage R1 and the second air passage R2 regardless of the operation. Therefore, the flow rate of the air flow passing through the air cleaning unit 3 and the air flow flowing in the first air passage R1. The following relationship is established between the flow rate and the flow rate of the airflow flowing through the second air passage R2.
(Flow rate of airflow passing through the air cleaning unit 3) = (Flow rate of airflow flowing through the first air passage R1) + (Flow rate of airflow flowing through the second air passage R2)

When performing the humidification operation, the multiblade fan 21 is driven so that the flow rate of the airflow flowing through the first air passage R1 is the highest in the efficiency of humidification by the humidification unit 5. At this time, since the air flow is also generated in the second air path R2 (R21, R22), the flow rate of the air flow flowing through the air cleaning unit 3 is larger than the flow rate of the air flow flowing through the first air path R1 from the above formula. . That is, the air flow is made to flow through the humidifying unit 5 at a flow rate at which the humidifying efficiency becomes the highest during the humidifying operation, and the air flow at a flow rate larger than the flow rate at which the efficiency becomes the highest in the humidifying operation can be made to flow through the air cleaning unit 3. it can. Similarly, an air flow is made to flow through the dehumidifying unit 4 at a flow rate at which the dehumidifying efficiency is highest during the dehumidifying operation, and air having a flow rate larger than the flow rate at which the efficiency is highest at the dehumidifying operation is supplied to the air cleaning unit 3. It can flow.

This makes it possible to maximize the efficiency of dehumidification during the dehumidifying operation or to maximize the efficiency of humidifying during the humidifying operation and to increase the efficiency of collecting foreign substances by the air cleaning unit 3. Further, in the dehumidifying / humidifying device A, the air sucked from the first suction port 16 and the second suction port 17 is blown out from the blowout port 15 through the first air passage R1 and the second air passage R2 (R21, R22). The Therefore, when the dehumidifying / humidifying operation is performed by the dehumidifying / humidifying device A, the flow rate of the airflow released to the outside is larger than when a conventional dehumidifier or humidifier is used alone. Therefore, it is possible to spread the dehumidified or humidified airflow far.

In addition, when the airflow of the flow volume which the humidification efficiency with respect to the airflow by the humidification unit 5 becomes the maximum flows through 1st airflow path R1, the efficiency of the dehumidification with respect to the airflow by the dehumidification unit 4 is maximum in 2nd airflow path R2 (R21, R22). You may form the air blower 2, the dehumidification unit 4, the humidification unit 5, 1st air path R1, and 2nd air path R2 (R21, R22) so that it may become the flow volume which becomes. By doing in this way, it is possible to maximize the efficiency of dehumidification and humidification and to increase the efficiency of air cleaning by rotating the multi-blade fan 21 of the blower 2 at a constant speed. In addition, since the dehumidification or humidification is not performed when the air cleaning operation is performed, the multiblade fan 22 may be rotated at a higher speed.

In the present embodiment, the dehumidifying / humidifying device A has the humidifying unit 5 arranged on the first air path R1, that is, the first intake port 25 side of the blower 2, and the second air path R2, that is, the second intake air of the blower 2. Although the dehumidification unit 4 is arrange | positioned at the opening | mouth 26 side, it is not limited to this. The dehumidifying unit 4 may be arranged away from the second air inlet 26, or the humidifying unit 5 may be arranged away from the first air inlet 25. Further, the dehumidifying unit 4 may be disposed in the first air path R1, and the humidifying unit 5 may be disposed in the second air path R2.

In the present embodiment, the second air passage R2 of the dehumidifying / humidifying device A includes the upper air passage R21 and the lower air passage R22 that bypass the fan case 22 of the blower 2, but is not limited thereto. For example, only one of the upper air path R21 and the lower air path R22 may be provided. As the second air passage R2 of the dehumidifying / humidifying device A of the present embodiment, the upper air passage R21 and the lower air passage R22 are provided, so that the air flow is not biased over a wide range of the evaporator 41. Therefore, it is possible to increase the dehumidification efficiency.

In addition, although the second flow path R2 bypasses the blower 2 up and down, the second flow path R2 may bypass the blower 2 in the horizontal direction instead of up and down, in other words, in the lateral direction. Further, the blower 2 may be bypassed in the vertical and horizontal directions. An air flow having a flow rate that allows the dehumidifying unit 4 or the humidifying unit 5 to operate efficiently can be flowed in the second air path R2, and an air path that bypasses the blower 2 can be widely used.

Yes. In the example shown in FIGS. 7 and 8, for convenience, the shape of the housing 1 including the case 11, the front cover 12, the rear cover 13, and the like is different from that of the dehumidifying / humidifying device A, but has substantially the same structure. Yes. Hereinafter, in the description of the dehumidifying / humidifying device C, substantially the same parts as the dehumidifying / humidifying device A are denoted by the same reference numerals, and detailed description of the same parts is omitted.

As shown in FIGS. 7 and 8, the blower 2 is arranged so that the rotation axis of the multiblade fan 21 is horizontal, but has substantially the same configuration as the multiblade fan 2 of the dehumidifying / humidifying device A. is doing. That is, the first intake port 25 is provided on the back side and the second intake port 26 is provided on the front side. In the dehumidifying / humidifying device C, the dehumidifying unit 4 is provided so as to be adjacent to the first air inlet 25.

7 and 8, a partition member 18 is disposed below the dehumidifying unit 4. In the dehumidifying / humidifying device C, the first suction port 16 is above the partition member 18 of the opening 111 when viewed from the back side, and the second suction port 17 is below the partition member 18. The dehumidifying unit 4 is provided so that the air sucked from the first suction port 16 enters the evaporator 41 of the dehumidifying unit 4.

The humidifying unit 5 c includes a humidifying member 56, a humidifying tray 57, and a housing 58. The humidifying member 56 is a member that can suck up moisture by capillary action and is accommodated in the humidifying tray 57. The humidifying tray 57 is a container capable of storing water. Water is supplied to the humidifying tray 57 from a humidifying tank (not shown). The humidifying member 56 is accommodated in the humidifying tray 57 so that the lower part is accommodated in water.

The humidifying member 56 and the humidifying tray 57 are accommodated in the housing 58 and attached to the case 11. The housing 58 is a cylindrical member formed of an airtight material, and is a member that houses the humidifying member 56 and the humidifying tray 57, and holds the humidifying member 56 so that the humidifying member 56 is not bent or broken. As a role. Such a humidifying unit 5c has a simple structure and can be miniaturized as compared with the humidifying unit 5 used in the dehumidifying / humidifying device A or the like. The housing 58 is disposed below the fan case 22 with a space therebetween.

7 and 8, a space through which airflow can pass is formed between the upper surface of the housing 58 and the lower surface of the fan case 22. In the dehumidifying / humidifying device C, the first damper 61 is provided in this space. The first damper 61 includes a curved surface 611 and a rotation support portion 612. The curved surface 611 is a part of a cylindrical shape and has a width in the depth direction of the drawing. The first damper 61 is pivotally supported by a rotation support portion 612 and opens and closes the air passage by rotating around the central axis of the curved surface 611. The first damper 61 is automatically rotated in accordance with the operation of the dehumidifying / humidifying device C, and is driven by power from a power source (not shown).

A receiving member 63 is provided on the inner surface of the front cover 12. The receiving member 63 is a regulating member for preventing the damper from rotating any further. As shown in FIG. 7, when the first damper 61 rotates most clockwise in FIG. 7, the end of the curved surface 611 comes into contact with the receiving member 63 and the rotation is restricted. As shown in FIG. 9, when the end portion of the first damper 61 is in contact with the receiving member 63, the airflow passes between the fan case 22 and the housing 58 and passes through the fan case 22 from the second air inlet 26. Flows into the interior. The state of the first damper 61 at this time is an open state. At this time, no airflow flows through the second air passage R2.

As shown in FIG. 8, when the first damper 61 rotates most counterclockwise in FIG. 8, the end of the curved surface 611 opposite to the end contacting the receiving member 63 contacts the fan case 22. To do. As shown in FIG. 10, when the end of the first damper 61 is in contact with the fan case 22, the curved surface 611 closes the space between the fan case 22 and the housing 58, so that the airflow passes through the humidifying unit 5c. . The state of the first damper 61 at this time is a closed state. At this time, the airflow flows through the second air path R2.

7 and 8, a gap is formed between the partition member 18 and the fan case 22. This gap is configured such that a part of the airflow that passes through the dehumidifying unit 4 and flows into the first intake port 25 can pass through the fan case 22 and the housing 58. The dehumidifying / humidifying device C is provided with a second damper 62 that opens and closes a gap with a flat plate member rotatably provided on the partition member 18. When the second damper 62 is in the closed state, the airflow that passes through the dehumidifying unit 4 and flows into the first intake port 25 does not flow from the gap to the fan case 22 and the housing 58. On the other hand, when the second damper 62 is in the open state, the airflow that passes through the dehumidifying unit 4 and flows into the first intake port 25 flows from the gap to the fan case 22 and the housing 58. The second damper 62 opens and closes automatically in accordance with the operation of the dehumidifying / humidifying device C, and is driven by power from a power source (not shown). Further, the power source of the first damper 61 and the second damper 62 may be shared.

The operation type of the dehumidifying / humidifying device C is the same as that of the dehumidifying / humidifying device A, that is, an air cleaning operation, a dehumidifying operation, and a humidifying operation. First, the dehumidifying operation will be described. During the dehumidifying operation, as shown in FIG. 9, the first damper 61 is opened and the second damper 62 is closed. When the multiblade fan 21 is driven in this state, air is sucked into the fan case 22 from the first air inlet 25 and the second air inlet 26, and an air current is generated. In the dehumidifying / humidifying device C, air is sucked from each of the first suction port 16 and the second suction port 17. The air sucked from the first suction port 16 flows through the first air path R1 that reaches the blowout port 15 through the dehumidifying unit 4, the first intake port 25, the fan case 22, and the discharge port 24.

On the other hand, the air sucked from the second suction port 17 passes through the space between the fan case 22 and the housing 58, passes through the second suction port 26, the fan case 22, the discharge port 24, and reaches the blowout port 15. It flows through a certain third air path R3. The airflow flowing through the third air path R3 does not pass through the humidifying unit 5c and is blown out from the blowout port 15.

Next, the humidifying operation will be described. As shown in FIG. 10, during the humidifying operation, the first damper 61 is closed and the second damper is opened. By closing the first damper 61, the space between the fan case 22 and the housing 58, which is a part of the third air path R3, is closed by the first damper 61. Therefore, the air sucked from the second suction port 17 flows through the second air path R2 that reaches the blowout port 15 through the humidification unit 5c, the second suction port 26, the fan case 22, and the discharge port 24. In addition, since the second damper 62 is opened, a bypass air passage in which a part of the air that has passed through the first suction port 16 is an air passage that branches and flows from the first air passage R1 to the second air passage R2. It flows through R4 and merges with the second air path R2.

That is, during the humidification operation, air that has been sucked in from the second suction port 17 and air that has passed through the bypass air passage R4 out of the air sucked in from the first suction port 16 flows through the second air passage R2 and is humidified. And blown out from the blowout port 15. Since the dehumidifying unit 4 is stopped during the humidifying operation, the air that has passed through the bypass air path R4 and joined to the second air path R2 is not dehumidified. Therefore, the humidity is the same as or substantially the same as the air sucked from the second suction port 17, and the flow rate of the humidified air can be increased while suppressing the fluctuation of the humidity.

In addition, since dehumidification and humidification are not performed during the air cleaning operation, the first damper 61 is opened and the second damper is formed so that the first air path and the third air path are formed as in the dehumidifying operation. 62 is closed to drive.

In the dehumidifying / humidifying device C, during the air cleaning operation and the dehumidifying operation, the first damper 61 is opened and the second damper 62 is closed so that the airflow does not pass through the second air path R2. Thereby, it can suppress that a part of airflow will be humidified at the time of an air cleaning driving | operation or a dehumidification driving | operation. For example, when switching to the air cleaning operation because the indoor humidity has sufficiently increased during the humidifying operation, air that has not been humidified, that is, that has not been humidified, can be blown out immediately after switching. Air that has not been humidified is blown out without waiting for the humidifying member 56 to dry.

Further, during the air cleaning operation or the dehumidifying operation, since the air current does not pass through the humidifying unit 5c, it is not necessary to dry the dehumidifying member 56 every time the operation is switched. Thereby, immediately after switching from the air cleaning operation or the dehumidifying operation to the humidifying operation, the humidified air is blown out without waiting for the time for the dehumidifying member 56 to spread water.

For these reasons, the dehumidifying / humidifying device C has high responsiveness when switching from the air cleaning operation or dehumidifying operation to the humidifying operation, or from the humidifying operation to the air cleaning operation or the dehumidifying operation.

In the dehumidifying / humidifying device A, the second damper 62 is opened during the humidifying operation, and air is diverted from the first air passage R1 to the second air passage R2 via the bypass air passage R4. This is the same as operating a part of the first suction port 16 as the second suction port 17 according to the operation. Thereby, even if the opening 111 is small, it is possible to flow an air flow that is highly efficient for dehumidification or humidification to the dehumidification unit or the humidification unit. That is, it is possible to reduce the size of the dehumidifying / humidifying device without reducing the efficiency of dehumidification and humidification.

In addition, when the 2nd inlet 17 is a magnitude | size which can generate | occur | produce the airflow of the flow volume which can improve the efficiency of humidification, you may make it perform humidification operation, with the 2nd damper 62 closed. Further, when the second suction port 17 is of a size that can flow an airflow having a flow rate that maximizes the humidifying efficiency of the humidifying unit 5c even when there is no air from the bypass air passage R4, the second damper 62 is omitted. Also good.

Further, the opening degree of the first damper 61 and the second damper 62 may be adjustable. By doing in this way, air can be made to distribute and flow to 2nd wind path R2 and 3rd wind path R3 at the time of humidification operation. Thereby, the amount of air to be humidified, in other words, the amount of moisture applied to the air can be adjusted, and the humidity can be adjusted.

In the present embodiment, the first damper 61 employs a configuration having a cylindrical curved surface 611 and a rotation support portion 612, but is not limited thereto. For example, a damper that adjusts the flow rate by opening and closing by rotating a flat plate may be used. It is possible to widely employ a damper that can adjust the flow rate of the airflow flowing through the humidifying unit 5c.
