In the following description, the state shown in fig. 1 is used as the dehumidification and humidification apparatus a, and the left side is the front side (front surface) and the right side is the back side (rear surface).
The dehumidification and humidification device a sucks ambient air, and has an air purification function of removing foreign matters such as dust contained in the air, a dehumidification function of removing moisture contained in the air, and a humidification function of increasing the humidity in the air. The dehumidification and humidification device a includes a casing 1, a blower 2, an air purification unit 3, a dehumidification unit 4, and a humidification unit 5.
The casing 1 is an outer member of the humidifier apparatus a, and includes a casing 11, a front cover 12, a rear cover 13, a light shielding plate 14, an air outlet 15, an air inlet 16, and a partition 18. The housing 11 is a box-shaped member having a space therein, and has a rectangular parallelepiped shape. The case 11 is formed using, for example, a metal plate, a synthetic resin, or the like, but is not limited thereto.
As shown in fig. 1, the housing 11 is used in a vertically upright state, and the surfaces facing opposite sides are a front surface and a back surface. The front and rear surfaces have openings, and a front cover 12 and a rear cover 13 are detachably attached to the front and rear surfaces, respectively. The front cover 12 and the rear cover 13 are protective members for preventing the hands of the user and the like from entering the internal devices of the casing 1 carelessly, and function as reinforcing members by being attached to the housing 11. Further, by detaching the front cover 12 or the rear cover 13, maintenance, inspection, and the like of the internal devices, that is, the blower 2, the air cleaning unit 3, the dehumidifying unit 4, the humidifying unit 5, and the like can be performed.
The casing 1 removes foreign matter from air sucked through the suction port 16 provided in the rear cover 13, and blows out humidified or dehumidified air from the outlet 15 as necessary. The outlet 15 has an opening on the upper surface when the humidifying/dehumidifying device a is set in the use state. A light shielding plate 14 is provided at the outlet 15. The light shielding plate 14 is a fin for adjusting the flow direction of the air blown out from the outlet 15, and is also used as a door capable of closing the outlet 15.
That is, the light shielding plate 14 is closed when the humidifying/dehumidifying device a is not operating, and is opened when the humidifying/dehumidifying device a starts operating. The light shielding plate 14 may be automatically opened or closed in response to the operation of the humidifying/dehumidifying device a, or may be manually opened or closed. In addition, the angle may be automatically opened to a certain angle and then manually adjusted to a desired angle.
As shown in fig. 4, an opening for disposing the air cleaning unit 3 is provided on the inner side of the rear cover 13 in the rear surface of the housing 11. The suction port 16 communicates with the opening. Intake port 16 is covered with an air cleaning filter 31 described later, and air passing through intake port 16 is sucked through air cleaning filter 31. The suction port 16 is an air inlet of an air passage R1 described later.
The blower 2 includes a sirocco fan 21, a fan case 22, a fan motor 23, a discharge port 24, and an intake port 25. Here, the sirocco fan 21 is a fan that discharges air in a centrifugal direction, and draws air from a central portion by rotation to generate an airflow to the periphery. Instead of the sirocco fan 21, a turbo fan or a high-pressure axial fan may be used.
In fig. 4, the upper portion of the blower 2 may be inclined so as to be close to the back side, may be inclined to the front side, or may not be inclined.
The sirocco fan 21 is configured to be rotatable in the interior of the fan housing 22. The fan housing 22 is connected to the discharge port 24, and has a structure capable of blowing an air flow generated in the circumferential direction of the sirocco fan 21 toward the discharge port 24. The fan casing 22 is provided with an air inlet 25, and the air inlet 25 is provided on one side in the axial direction of the sirocco fan 21. The fan casing 22 in the present embodiment is fixed inside the casing 11 such that the air inlet 25 faces the back side.
The sirocco fan 21 is attached to an output shaft of a fan motor 23. The fan motor 23 is fixed to the fan housing 22, and the rotary drive of the fan motor 23 rotates the sirocco fan 21. The discharge port 24 is an opening that discharges an airflow generated by the rotation of the sirocco fan 21. The discharge port 24 is cylindrical in shape communicating with the inside of the sirocco fan 21 provided with the fan housing 22. And, the discharge port 24 communicates with the air outlet 15.
That is, the air discharged from the discharge port 24 is blown out to the outside of the humidifying/dehumidifying device a through the outlet port 15. The outlet 15 is formed to have a certain length in the flow direction of the airflow, and can rectify the blown airflow and send the airflow to a remote place. Although not shown in the drawings, an ion generator may be disposed in the air outlet 15, and ions may be included in the air flow as necessary.
In particular, the ion generator is configured to generate ions by amplification in the atmosphere, and to generate positive ions H+(H2O) m, anion O2-(H2O) n, where m and n are each an arbitrary natural number, and positive and negative ions are allowed to attach to the surfaces of bacteria and viruses in the air to react with each other, thereby forming active substances OH groups (. OH) and hydrogen peroxide (H) on the surfaces2O2) Thereby achieving the sterilization effect.
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 provided in the back surface of the housing 11. The mesh 32 is a net-like member, is a protective member for preventing hands, tools, and the like from entering the inside from the opening, and is used as a filter for trapping dust contained in the air. The air cleaning filter 31 is a filter for capturing foreign matters such as fine dust and dust from air passing therethrough. The air cleaning filter 31 and the mesh 32 are detachably attached to the opening.
The Air cleaning Filter 31 may be a HEPA Filter (High Efficiency Particulate Air Filter) formed by forming a nonwoven fabric into a paper shape, but is not limited thereto. The air cleaning filter 31 has a higher foreign matter trapping efficiency as the amount of air passing therethrough increases and the flow rate of air flow increases. Further, the greater the amount of foreign matter captured by the air cleaning filter 31, the less likely the air passes through. Therefore, the rear cover 13 is detachable only by detaching it. The air cleaning filter 31 may be disposable or may be cleaned and reused. The air cleaning filter 31 may cover the opening in one piece or may cover the opening in two pieces. Further, the air cleaning filter 31 may have a deodorizing function, which is a method of applying a deodorizer or the like for removing odor in the air.
The dehumidifying unit 4 includes an evaporator 41, a condenser 42, a dehumidifying disk 43, and a dehumidifying tank 44. The dehumidifying unit 4 condenses moisture contained in the air by cooling the passing air flow, and removes the moisture in the air, that is, dehumidifies the air. The dehumidification unit 4 includes a refrigeration cycle device that cools air by using a phase change of a refrigerant through circulation of the refrigerant. The refrigeration cycle apparatus includes a compressor, an expander, and the like, which are not shown, in addition to the evaporator 41 and the condenser 42.
The evaporator 41 and the condenser 42 are heat exchangers, and examples thereof include, but are not limited to, heat exchangers using Fin tubes (Fin & tube). The dehumidifying unit 4 is disposed in the casing 1 at a position close to the blower 2. Air is drawn into the fan casing 22 from the air inlet 25 and sent out from the discharge port 24 in accordance with the driving of the blower 2, thereby generating an air flow flowing through the gaps between the fins of the evaporator 41 and the condenser 42 of the dehumidifying unit 4.
The evaporator 41 cools the airflow, i.e., air, and the condenser 42 heats the airflow. Therefore, in the dehumidifying unit 4, the evaporator 41 is disposed on the upstream side of the airflow to cool the airflow, and the evaporator 41 condenses moisture in the air. The air flow cooled in the evaporator 41 is heated by heat exchange with the high-temperature refrigerant in the condenser 42, and is raised to the same temperature as or higher than the temperature when flowing into the evaporator 41. In this way, in the dehumidification unit 4, the evaporator 41 is disposed on the upstream side of the air flow of the condenser 42.
The dehumidifying disk 43 is a container disposed below the evaporator 41, and is a receiving disk for receiving the condensed water condensed on the surface of the evaporator 41. The water received in the dehumidification disk 43 is sent to the dehumidification tank 44 through a not-shown line. The dehumidifying tank 44 is a container detachably provided in the housing 11 in a sliding manner.
The dehumidifying tank 44 can detect the amount or level of the accumulated condensed water. In the dehumidifying and humidifying device a, when the condensate water of the dehumidifying tank 44 is accumulated to a certain amount, a warning is issued, and at least the dehumidifying unit 4 of the dehumidifying and humidifying device a is stopped. The user removes the dehumidifying tank 44 according to the warning and discharges the accumulated condensed water, thereby reusing the dehumidifying function.
In the present embodiment, dehumidification is performed using a refrigeration cycle, but the present invention is not limited to this, and a dehumidification unit using a desiccant or the like that absorbs moisture in the air may be used.
Next, the humidifying unit is explained with reference to fig. 3. The humidification unit 5 includes a humidification rotor 51, a drive motor 52, a humidification disk 53, a humidification member 54, and a humidification case 55. The humidifying rotor 51 includes a cylindrical portion 511 provided at an outer peripheral portion thereof, and a support portion 512 supporting an inner side of the cylindrical portion 511, and is supported rotatably inside the housing 11. A humidifying unit 54 that can contain water is disposed inside the cylindrical portion 511. The cylindrical portion 511 and the support portion 512 function as a holding member for holding the humidifying member 54.
The humidifying rotor 51 is rotatable, and the humidifying rotor 51 is rotated by an axial force output from the drive motor 52 transmitted thereto through a power transmission structure, not shown. The humidifying rotor 51 and the humidifying disc 53 are configured such that a lower portion of the humidifying rotor 51 passes through the inside of the humidifying disc 53. The cylindrical portion 511 of the humidifying rotor 51 incorporates a hard paper-like humidifying member 54 formed of a water-absorbing material, and the humidifying rotor 51 rotates to spread the water accumulated in the humidifying disc 53 over the entire humidifying member 54. Thereby, water is supplied to the humidifying member 54.
The humidifying member 54 includes a member having an infinite number of minute gaps such as a nonwoven fabric, and water is distributed over the entire surface by capillary phenomenon. The humidifying disc 53 and the humidifying tank 55 are connected by a pipeline, and water is added from the humidifying tank 55 in order to keep the humidifying disc 53 at a water amount or a water level equal to or higher than a certain level.
The humidifying rotor 51 may be rotated, and the plurality of humidifying members 54 may be individually held. Further, a part of the humidification rotor 51 may not have water absorption. By stopping the rotation in a state where the part is immersed in the humidifying disc 53, the supply of water to the humidifying disc 53 can be stopped. No new moisture is supplied except for moisture already contained in the humidification rotor 51, and therefore, humidification after drying of the humidification rotor 51 can be prevented.
The humidifying unit 5 is provided on the rear surface side of the dehumidifying unit 4 with respect to the blower 2 in the casing 1. When the blower 2 is driven to suck air from the air inlet 25 into the fan case 22, an airflow flowing in the axial direction is generated inside the cylindrical portion 511 of the humidification rotor 51. The humidifying member 54 is disposed inside the cylindrical portion 511, and when the humidifying member 54 holds moisture, the humidifying member 54 supplies moisture to the airflow, that is, humidifies the flowing air. Also, the position of the humidifying unit 5 is adjusted such that, in the case of the humidifying operation, the airflow flowing through the humidifying rotor 51 passes through the humidifying member 54 holding moisture.
In the humidifying/dehumidifying device a, the humidifying unit 5 is configured to be distributed by capillary phenomenon by rotating the humidifying rotor 51 to bring the humidifying member 54 into contact with the moisture accumulated in the humidifying disc 53, but is not limited thereto. For example, the humidifying rotor may be provided with a water tub at a circumferential portion thereof, and the water tub may be rotated to scoop water and flow the scooped water from above to the humidifying member. The humidifying disc 53 and/or the humidifying tank 55 may also have a function for suppressing the accumulated water from deteriorating, for example, a sterilizing function using antibacterial metal ions, a sterilizing function by a medicine, a function by electrolysis, or the like.
Next, an air passage, which is a flow path of the air flow in the humidifying/dehumidifying device a according to the present invention, will be described. Fig. 5 is a schematic view of a ventilation path of the humidifying and dehumidifying apparatus according to the present invention.
As shown in fig. 5, in the humidifying/dehumidifying device a, an air passage R1 is formed in which the air passing through the inlet port 16 passes from the air cleaning unit 3, through the humidifying unit 5, the dehumidifying unit 4, and the blower 2, and reaches the outlet port 15.
In the dehumidification/humidification device a, regardless of the operation of the dehumidification unit 4 and the humidification unit 5, the rotation driving of the sirocco fan 21 generates an air flow in the air passage R1. Suction port 16, which is a suction port of air passage R1, is covered with air cleaning filter 31, and the air flow passing through suction port 16 passes through air cleaning filter 31 to remove dust and the like.
The dehumidification and humidification device a is configured to selectively operate the dehumidification unit 4 and the humidification unit 5. That is, the control device, not shown, can switch between three operations, namely, the operation of the dehumidification unit 4 and the operation of the humidification unit 5, the operation of the dehumidification unit 4 alone, and the operation of the humidification unit 5 alone, all of which are stopped. Three operations are described below.
When both the dehumidification unit 4 and the humidification unit 5 are stopped, only the air purification operation of removing foreign substances by the air purification filter 31 of the air purification unit 3 is performed. That is, although the airflow generated in the air passage R1 passes through the humidification unit 5, the airflow is not humidified because the humidification unit 5 stops operating.
Further, the air flow passing through the humidifying unit passes through the dehumidifying unit 4, but the dehumidifying unit 4 stops operating, and therefore the air flow is not dehumidified. Therefore, the air sucked from the suction port 16 and discharged from the air outlet 15 is not dehumidified or humidified, although dust and the like are captured.
When only the dehumidifying unit 4 is operated, the air flow flowing through the air passage R1 passes through the non-operating humidifying unit 5, and is therefore not humidified. Further, the air flow passing through the humidifying unit 5 passes through the dehumidifying unit 4 that is operating, and is thus dehumidified. That is, the operation performed in the dehumidification operation of operating the dehumidification unit 4 is to capture foreign matters from the airflow by the air cleaning filter 31 and dehumidify the airflow flowing through the air passage R1.
When only the humidification unit 5 is operated, the air flow flowing through the air passage R1 passes through the humidification unit 5 that is being operated, and is thus humidified. Further, the air flow passing through the humidifying unit 5 will pass through the dehumidifying unit 4, but will not be dehumidified because the dehumidifying unit 4 stops operating. That is, the operation performed in the humidification operation for operating the humidification unit 5 is to capture foreign matter from the airflow by the air cleaning filter 31 and humidify the airflow flowing through the air passage R1.
The dehumidification and humidification apparatus of the present invention is subjected to the air purification operation, the dehumidification operation, and the humidification operation as described above. The air cleaning unit 3, the dehumidifying unit 4, and the humidifying unit 5 perform different operations, respectively. The efficiency of each operation varies depending on the flow rate of the airflow. For example, the more the air flow rate in the air cleaning unit 3, the higher the foreign matter trapping efficiency.
On the other hand, in the dehumidifying unit 4, dehumidification is performed by cooling air when the air flow passes through the evaporator 41 and generating condensation. Therefore, the air flow is preferably in contact with the evaporator 41 until the air flow is cooled to a temperature at which condensation occurs. Conversely, excessive contact may be inefficient due to the continued contact of the condensed gas stream with the evaporator 41. That is, the dehumidifying unit 4 has a flow rate that maximizes dehumidification efficiency.
Similarly, the humidifying unit 5 gives moisture to the air flow when the air flow passes through the humidifying component 54, and therefore, there is a flow rate at which the humidifying efficiency is maximized. Since the area in the direction intersecting the air flow is determined by the design of the evaporator 41 and the humidification unit 54, the flow rate at the optimum flow rate is the optimum flow rate of the dehumidification unit 4 or the humidification unit 5.
In the case of the humidification operation, it is preferable to control the flow rate of the air flowing through the air passage R1 by driving the sirocco fan 21 so as to maximize the humidification efficiency of the humidification unit 5. Further, in the case of performing the air cleaning operation, the air flowing to the air cleaning unit 3 is preferably a flow rate at which the efficiency of the air cleaning operation is the highest. Similarly, in the case of performing the dehumidification operation, the flow rate of the air flowing into the dehumidification unit 4 is preferably the flow rate at which the dehumidification efficiency is the highest.
These flow rates are determined when they are designed, and a program is provided in a control device, not shown, which is prestored as data relating to the rotation speed of the blower 2 and is automatically selected by an operation unit, not shown, when the user instructs the air cleaning operation, the humidifying operation, and the dehumidifying operation. Further, it may be performed in an automatic operation mode in which the air cleaning operation, the humidifying operation, and the dehumidifying operation are automatically selected.
In each of the above operation modes, the blower rotation speed, the higher rotation speed, or the higher rotation speed that realizes the optimum flow rate may be selected. In order to cope with different use conditions such as operation start and sleeping.
(second embodiment)
Examples of other dehumidifying and humidifying devices according to the present invention will be described with reference to the accompanying drawings. Fig. 4 is a schematic view of an air supply path of another example of the humidifying and dehumidifying apparatus according to the present invention. The humidifying/dehumidifying device B shown in fig. 6 has the same configuration as the humidifying/dehumidifying device a except that the position of the dehumidifying unit 4 is different. Therefore, the same reference numerals will be given to the same parts in practice, and detailed description of the same parts will be omitted.
As shown in fig. 6, the dehumidifying unit 4 and the humidifying unit 5 of the present embodiment are disposed at positions facing each other with the blower 2 therebetween. The humidification unit 5 is provided on the air purification unit 3 side.
The air inlet 25 of the blower 2 is disposed so as to face the dehumidifying unit 4, and the air sucked into the suction port 16 passes through the air cleaning unit 3, passes through the humidifying unit 5, bypasses the peripheral portion of the blower 2 from the lower portion of the partition 18, and is supplied to the dehumidifying unit 4. Then, the air sucked into the fan case 22 from the air inlet 25 of the blower 2 passes through the air outlet 15 via the discharge port 24 of the fan case 22 and is blown upward.
As described above, by arranging the dehumidifying unit 4 so that the opening direction of the suction port 16 and the opening direction of the air inlet 25 of the blower 2 are opposite to each other, wind noise generated by the sirocco fan 21 is not directly directed toward the suction port 16 and hardly transmitted to the outside of the casing 1, and therefore, low noise can be realized.
Further, the humidifying unit 5, which requires daily maintenance, is disposed near the opening on the back side, and therefore maintenance is facilitated.
(third embodiment)
Another example of the humidifying/dehumidifying apparatus according to the present invention will be described with reference to fig. 7. Fig. 7 is a schematic view of an air supply path of another example of the humidifying and dehumidifying apparatus according to the present invention. The humidifying/dehumidifying device C shown in fig. 7 has the same configuration as the humidifying/dehumidifying device a except that the positions of the dehumidifying unit 4 and the humidifying unit 5 are different. Therefore, the same reference numerals are given to the same parts, and detailed description thereof is omitted.
As shown in fig. 7, the dehumidifying unit 4 and the humidifying unit 5 are disposed at positions facing the suction port 16 with the blower 2 interposed therebetween. That is, the blower 2 is disposed on the back side of the dehumidification unit 4 and the humidification unit 5 in the interior of the casing 1.
The air inlet 25 of the blower 2 opens in the front direction of the casing 1 on the side where the dehumidifying unit 4 and the humidifying unit 5 are disposed, and the air sucked from the suction port 16 passes through the air cleaning unit 3, passes through the lower part of the partition 18, bypasses the periphery of the blower 2, passes through the humidifying unit 5, and is supplied to the dehumidifying unit 4. Then, 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 discharge port 24.
As described above, by arranging the dehumidifying unit 4 and the humidifying unit 5 so that the opening direction of the suction port 16 and the opening direction of the blower 2 are opposite to each other, wind noise generated by the sirocco fan 21 is less likely to be transmitted to the outside of the casing 1, and low noise can be achieved.
Further, since the front cover 12 is configured to be openable, the humidifying rotor 51 and the humidifying disc 53, which require daily maintenance, can be easily operated since the humidifying unit 5 is located on the front side of the dehumidifying unit 4.
