The blower 2 includes a multiblade fan 21, a fan case 22, a fan motor 23, a discharge port 24, and an intake port 25. 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. A turbo fan or a high-pressure axial fan may be used in place of the multiblade fan 21.

In FIG. 4, the blower 2 is tilted so that the upper part approaches the back side, but may be tilted forward or may not be tilted.

The multiblade fan 21 is rotatably arranged inside the fan case 22. The fan case 22 is connected to the discharge port 24, and has a configuration capable of blowing airflow generated in the circumferential direction of the multiblade fan 21 toward the discharge port 24. The fan case 22 is provided with an intake port 25 provided on one side of the multiblade fan 21 in the axial direction.

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 air outlet 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 blower outlet 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 reach far. In addition, although illustration is abbreviate | omitted, an ion generator may be arrange | positioned at the blower outlet 15, and you may make it include ion in an airflow as needed.

In particular, the ion generator is discharged in the atmosphere to generate ions, and positive ions H ⁺ (H ₂ O) m and negative ions O ²⁻ (H ₂ O) where m and n are arbitrary natural numbers, respectively. When n is generated, positive and negative ions attach to the surface of airborne bacteria and viruses in the air and react to generate active species OH radicals (.OH) and hydrogen peroxide (H ₂ O ₂ ) on the surface. Effects such as sterilization can be exhibited.

The air cleaning filter 31 is a filter that collects foreign matters such as fine dust and dust from the passing air. The air purifying filter 31 and the mesh 32 are detachably attached to the opening.

Examples of the air purification filter 31 include, but are not limited to, a HEPA filter (High Efficiency Particulate Air Filter) in which a nonwoven fabric is formed in a paper shape. The air cleaning filter 31 has a higher foreign matter collection efficiency as the amount of air passing through the air purifier 31 increases and the flow rate of the airflow 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. The air purification filter 31 may cover the opening with one piece, or may cover the opening in a divided manner. Moreover, the air purifying filter 31 may have a deodorizing function by a method of carrying a deodorizing agent that removes an odor or the like in the air.

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 airflow 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, a heat exchanger using fins and tubes. The dehumidifying unit 4 is disposed close to the blower 2 in the housing 1. As the blower 2 is driven, air is sucked into the fan case 22 from the intake port 25 and sent out from the discharge port 24, so that an airflow flowing through the gaps between the evaporator 41 of the dehumidifying unit 4 and the fins of the condenser 42 is generated. .

The evaporator 41 cools the airflow, that is, the air, and the condenser 42 warms the airflow. Therefore, in the dehumidifying unit 4, the evaporator 41 is arranged on the upstream side of the airflow to cool the airflow, and the moisture in the air is condensed on the evaporator 41. Then, the air flow cooled by the evaporator 41 is warmed by heat exchange with a high-temperature refrigerant by the condenser 42, and the temperature is raised to the same or higher temperature as when it flows into the evaporator 41. From the above, in the dehumidifying unit 4, the evaporator 41 is arranged upstream of the air flow than the condenser 42.

Further, the dehumidifying tray 43 is a container arranged at the lower part of the evaporator 41 and is a tray for receiving condensed water condensed on the surface of the evaporator 41. And the water received with the dehumidification tray 43 is sent to the dehumidification tank 44 via piping 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 or level of accumulated drain water. In the dehumidifying / humidifying device A, when a certain amount of drain water is accumulated in the dehumidifying tank 44, a warning is given and at least the dehumidifying unit 4 of the dehumidifying / humidifying device A is stopped. The user removes the dehumidifying tank 44 in response to the warning and drains the accumulated drain water, so that the dehumidifying function can be used again.

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 desiccant or the like that adsorbs moisture in the air may be used.

Next, the humidification unit will be described with reference to FIG. 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. 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 inside the case 11. A humidifying member 54 that can contain water is disposed inside the cylindrical portion 511. 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 humidifying rotor 51 incorporates a corrugated cardboard humidifying member 54 made of a material having water absorption properties, and humidifies the water accumulated in the humidifying tray 53 when the humidifying rotor 51 rotates. Water is distributed throughout the member 54. Thereby, water is supplied to the humidifying member 54.

The humidifying member 54 is provided with a member having innumerable minute gaps such as a nonwoven 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 amount of water or the water level exceeds a certain level.

The humidifying rotor 51 may be configured to rotate, and the plurality of humidifying members 54 may be held independently. Moreover, it is good also as a structure where a part of humidification rotor 51 does not have water absorption. By stopping the rotation while this part is immersed in the humidifying tray 53, the supply of water from the humidifying tray 53 can be stopped. Since new water is not supplied except for the water already contained in the humidification rotor 51, it is possible to prevent humidification after the humidification rotor 51 is dried.

The humidification unit 5 is provided in the housing 1 on the rear side of the dehumidification unit 4 with respect to the blower 2. When air is sucked into the fan case 22 from the air inlet 25 by driving the blower 2, an airflow that flows in the axial direction inside the cylindrical portion 511 of the humidifying rotor 51 is generated. A humidifying member 54 is disposed inside the cylindrical portion 511. When the humidifying member 54 holds water, the humidifying member 54 supplies water to the airflow, that is, humidifies the flowing air. The position of the humidifying unit 5 is adjusted so that the airflow flowing through the humidifying rotor 51 passes through the humidifying member 54 that holds water during the humidifying operation.

In the dehumidifying / humidifying device A, the humidifying unit 5 is configured to rotate the humidifying rotor 51 so that the humidifying member 54 comes into contact with the water stored in the humidifying tray 53 and spreads by capillary action. It is not limited to. For example, a structure in which a bucket is installed on the circumferential portion of the humidification rotor, water is scooped by rotation, and the scooped water is allowed to flow from the top to the humidification member. It should be noted that the humidifying tray 53 and / or the humidifying tank 55 have a function for preventing the accumulated water from deteriorating, for example, a sterilization function using antibacterial metal ions, a sterilization function by chemicals, and electrolysis. May be provided with a sterilization function.

Next, the air path which 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 a ventilation path of the dehumidifying / humidifying device according to the present invention.

As shown in FIG. 5, in the dehumidifying / humidifying device A, an air path R1 is formed in which the air that has passed through the suction port 16 extends from the air cleaning unit 3 to the air outlet 15 through the humidifying unit 5, the dehumidifying unit 4, and the blower 2. Has been.

In the dehumidifying / humidifying device A, an air flow is generated in the air path R1 by the rotational drive of the multiblade fan 21 regardless of the operations of the dehumidifying unit 4 and the humidifying unit 5. The air inlet 16 which is the air inlet of the air passage R1 is covered with an air purifying filter 31, and the airflow passing through the air inlet 16 passes through the air purifying filter 31 to remove dust and the like.

The dehumidifying / humidifying device A has a configuration capable of selectively operating the dehumidifying unit 4 and the humidifying unit 5. That is, it is possible to switch to three types of operations: a control device (not shown) that stops both the dehumidifying unit 4 and the humidifying unit 5, operates only the dehumidifying unit 4, and operates only the humidifying unit 5. . 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 is performed so as to remove foreign substances with the air cleaning filter 31 of the air cleaning unit 3. That is, the airflow generated in the air passage R1 passes through the humidification unit 5, but the airflow is not humidified because the humidification unit 5 is stopped.

Furthermore, although the airflow that has passed through the humidification unit passes through the dehumidification unit 4, the airflow is not dehumidified because the dehumidification unit 4 is stopped. For this reason, the air sucked from the suction port 16 and blown from the blower outlet 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 air path R1 passes through the humidifying unit 5 that is not operating, and thus is not humidified. Moreover, since the airflow that has passed through the humidifying unit 5 passes through the operating dehumidifying unit 4, it is dehumidified. That is, in the dehumidifying operation in which the dehumidifying unit 4 is operated, the foreign substance is collected from the air current by the air cleaning filter 31 and the air current flowing through the air path R1 is dehumidified.

When only the humidifying unit 5 is operated, the airflow flowing through the air path R1 passes through the operating humidifying unit 5 and is thus humidified. Moreover, although the airflow which passed the humidification unit passes the dehumidification unit 4, since the dehumidification unit 4 has stopped, dehumidification of an airflow is not performed. That is, in the dehumidifying operation in which the humidifying unit 5 is operated, the air purification filter 31 collects foreign substances from the air current and the air current flowing through the air path R1 is humidified.

In the dehumidifying / humidifying device of the present invention, the air cleaning operation, the dehumidifying operation, and the humidifying operation are performed as described above. 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 until it is 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 at which the dehumidifying efficiency is highest.

Similarly, since the humidifying unit 5 imparts moisture to the airflow when passing through the wet humidifying member 54, there is a flow rate at which the efficiency of humidification becomes the highest. Since the area in the direction intersecting with the air flow is determined at the time of designing the evaporator 41 and the humidifying member 54, the optimal flow rate is the optimal flow rate in the dehumidifying unit 4 or the humidifying unit 5.

When performing the humidification operation, it is preferable to drive the multiblade fan 21 so that the flow rate of the airflow flowing through the air passage R1 is the highest in the efficiency of humidification by the humidification unit 5. In addition, when performing the air cleaning operation, it is preferable to flow air at a flow rate at which the efficiency is highest in the air cleaning operation. Similarly, it is preferable to flow the airflow to the dehumidifying unit 4 at a flow rate at which the dehumidifying efficiency is highest during the dehumidifying operation.

These flow rates are matters determined at the time of design, and are stored in advance as data relating to the number of rotations of the blower 2 in a control device (not shown), and the user performs an air cleaning operation and humidification from an operation unit (not shown). The program is configured to automatically select when operation or dehumidification operation is instructed. It can also be implemented in an automatic operation mode in which an air cleaning operation, a humidifying operation, and a dehumidifying operation are automatically selected and executed.

In addition, in each said operation mode, you may comprise so that higher rotation speed or low rotation speed can be selected including the rotation speed of the fan which can implement | achieve optimal flow volume. This is in order to cope with various usage situations such as when driving or at bedtime.

Further, the air inlet 25 of the blower 2 is disposed so as to face the dehumidifying unit 4, and the air sucked from the air inlet 16 passes through the air purifying unit 3 and is then partitioned via the humidifying unit 5. The dehumidifying unit 4 is supplied from the lower part of the part 18 by bypassing the peripheral part of the blower 2. Thereafter, the air sucked into the fan case 22 from the air inlet 25 of the blower 2 is blown upward from the air outlet 15 via the discharge port 24 of the fan case 22.

As described above, since the dehumidifying unit 4 is arranged, the opening direction of the suction port 16 and the opening direction of the intake port 25 of the blower 2 are opposite to each other, so that the wind noise generated by the multiblade fan 21 is directly generated. Since it will not go to the suction inlet 16, it will become difficult to go out of the housing | casing 1, and noise reduction can be achieved.

Also, since the humidifying unit 5 that is routinely maintained is installed near the opening on the back side, convenience is maintained.

FIG. 7 is a view showing an air blowing path of another example of the dehumidifying / humidifying device according to the present invention. The dehumidifying / humidifying device C shown in FIG. 7 has the same configuration as the dehumidifying / humidifying device A except that the positions of the dehumidifying unit 4 and the humidifying unit 5 are different. Therefore, substantially the same parts are denoted by the same reference numerals, and detailed description of the same parts is omitted.

As shown in FIG. 7, the dehumidifying unit 4 and the humidifying unit 5 are installed at positions facing the suction port 16 with the blower 2 interposed therebetween. That is, the blower 2 is arranged on the back side of the housing 1 rather than the dehumidifying unit 4 and the humidifying unit 5.

Further, the air inlet 25 of the blower 2 is opened on the side where the dehumidifying unit 4 and the humidifying unit 5 are arranged, that is, in the forward direction of the housing 1, and the air sucked from the air inlet 16 is the air purifying unit 3. After passing, the detour around the periphery of the blower 2 via the lower part of the partition 18, passes through the humidifying unit 5, and is supplied to the dehumidifying unit 4. Thereafter, the air sucked into the fan case 22 from the air inlet 25 of the blower 2 is blown upward from the air outlet 15 through the outlet 24.

As described above, since the dehumidifying unit 4 and the humidifying unit 5 are arranged, the opening direction of the suction port 16 and the opening direction of the blower 2 are opposite to each other. It becomes difficult to go out of the body 1, and noise can be reduced.

Moreover, since the humidifying unit 5 is located on the front side of the dehumidifying unit 4 by opening the front cover 12, the humidifying rotor 51 and the humidifying tray 53 that require daily maintenance are easy to handle. I can do it.

In addition, by adopting a structure in which the front cover 12 is opened, it is not necessary to move the dehumidifying / humidifying device from the side of the wall or to rotate behind the dehumidifying / humidifying device each time the humidifying unit 5 is cleaned.
