Description

Technical Field

[0001] The present application relates to the field of air conditioning technology, and in particular to a waterless humidifying device and an air conditioner. Background Art

[0002] Currently, air conditioners are available on the market that use waterless humidification devices to achieve waterless humidification. Existing waterless humidification devices include two fans, a humidification rotor, and a heating assembly. The principle is that the first fan forms a first air path, which runs from outdoor to outdoor. A section of the humidification rotor is located in this first air path, thereby absorbing moisture from the outdoor air. The second fan forms a second air path, which runs from outdoor to indoor. The other section of the humidification rotor and the heating assembly are located in this second air path. As the hot air passes through the humidification rotor, it removes the moisture adsorbed on the humidification rotor and flows into the room, thereby humidifying the indoor environment.

[0003] Currently, the cost is relatively high due to the use of two fans and the provision of two completely independent air ducts. Summary of the Invention

[0004] The problem solved by the present application is that the existing waterless humidification devices have high costs and large volumes.

[0005] In order to solve the above problems, in the first aspect, the present application provides a waterless humidifying device, comprising a shell assembly, a fan, a heating assembly, a humidifying wheel and a driving member; the shell assembly has an air duct and an air inlet, an indoor air outlet and an outdoor air outlet connected to the air duct, the fan, the heating assembly and the humidifying wheel are all arranged in the air duct, and a diverter plate is provided in the air duct downstream of the fan along the air flow direction, the diverter plate is used to divide the air flow sent out by the fan into a first air path and a second air path, the first air path is sent out from the outdoor air outlet, and the second air path is sent out from the indoor air outlet. Furthermore, the humidifying wheel is arranged downstream of the diverter plate, and a part of the humidifying wheel is located in the first air path and the other part is located in the second air path, the heating assembly is located in the second air path between the humidifying wheel and the diverter plate, the driving member is used to drive the humidifying wheel to rotate, and the humidifying wheel is used to absorb moisture from the first air path and supply moisture to the second air path.

[0006] In an embodiment of the present application, a diverter plate is used to divert the airflow generated by a fan, thereby forming a first air path and a second air path. The first air path is used to provide moisture to the humidification rotor, and the second air path is used to bring the moisture in the humidification rotor into the room. The diverter plate is used to form two air paths through a single fan, thereby reducing costs. On the other hand, because the number of fans is reduced, the fan position and the upstream air duct of the fan do not need to be divided into two isolated air ducts, so the overall structure is more compact and stable.

[0007] In an optional embodiment, the housing assembly includes a volute and a rotor housing, the fan is disposed in the volute, and the humidifying rotor is disposed in the rotor housing. Furthermore, the volute has a volute outlet portion, the inner cavity of the volute is connected to the rotor housing through the volute outlet portion, and at least a portion of the diverter plate is located in the volute outlet portion. Because the humidifying rotor is housed in the rotor housing, and the rotor housing receives airflow from the volute outlet portion, the diverter plate is disposed at the volute outlet portion so that the airflow entering the rotor housing is divided into two paths, each passing through different areas of the humidifying rotor. The diverter plate does not occupy too much space in the rotor housing, making the structure more compact.

[0008] In an optional embodiment, the impeller housing is arranged on one side of the volute in the radial direction, the fan is a centrifugal fan, and the axis of the fan is perpendicular to the axis of the humidifying impeller.

[0009] In an alternative embodiment, a portion of the volute and a portion of the impeller housing are integrally connected to form a first integrated cover, and another portion of the volute and another portion of the impeller housing are integrally connected to form a second integrated cover. A diverter plate is disposed within the first integrated cover, and abuts the inner wall of the second integrated cover after the first and second integrated covers are assembled. In this embodiment, the diverter plate is disposed within the first integrated cover, with its other side abutting the second integrated cover when assembled. This arrangement eliminates the formation of a seam in the middle of the volute outlet, resulting in a better diversion effect.

[0010] Furthermore, the volute has a volute tongue, and the upstream end of the diverter plate is located downstream of the volute tongue. By arranging the upstream end of the diverter plate downstream of the volute tongue, the diverter plate is prevented from being too close to the middle of the fan chamber and affecting the fan air output.

[0011] In an optional embodiment, the heating component is arranged in the rotor housing, the upstream end of the diverter plate is located in the outlet of the volute, the downstream end of the diverter plate extends into the rotor housing, and one side of the diverter plate faces the heating component. In this embodiment, the downstream end of the diverter plate extends into the rotor housing to improve the diversion effect, avoid the first air path and the second air path entering the rotor housing from re-intersecting, and ensure that they blow to different areas of the humidification rotor. One side of the diverter plate faces the heating component, and the airflow separated on this side belongs to the second air path. The airflow in this air path will be heated by the heating component. The airflow with a higher temperature has a higher saturated vapor pressure and can therefore remove moisture from the wet humidification rotor; the airflow on the other side is away from the heating component and belongs to the first air path. It will not be heated by the heating component. The cold air has a lower saturated vapor pressure. Therefore, the moisture in the gas in the first air path tends to (or is) saturated and is easily adsorbed by the humidification rotor.

[0012] In an optional embodiment, the downstream end of the diverter plate is bent toward the side where the heating assembly is located. By bending the downstream end of the diverter plate toward the side of the heating assembly, the second air path is facilitated to pass through the heating assembly and be fully heated by the heating assembly.

[0013] In an optional embodiment, the first air path and the second air path have the same cross-sectional area at the volute outlet. In this embodiment, the same cross-sectional area of ​​the first air path and the second air path means that the air volume is approximately equal, which is conducive to balancing the moisture absorption and humidification of the humidification wheel.

[0014] In an optional embodiment, the housing assembly further includes an air collecting box connected to the volute, which houses the filter assembly, with the air inlet disposed in the air collecting box. Because fresh air from outside is introduced into the room via the waterless humidifier, the air collecting box and filter assembly are provided to filter and clean the incoming air, preventing the fresh air from contaminating the indoor environment in harsh environments.

[0015] In an optional embodiment, the housing assembly further includes a runner end cover, the runner housing has an opening at one end away from the volute, the runner end cover is arranged at the opening, and the indoor air outlet and the outdoor air outlet are both arranged at the runner end cover.

[0016] In an optional embodiment, the driving member is provided on the end cover of the runner.

[0017] In a second aspect, the present application provides an air conditioner, comprising an air conditioner main body and a waterless humidifying device according to any one of the aforementioned embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The existing waterless humidification device has two independent air ducts, which are formed by two fans in the two air ducts, namely the first air duct and the second air duct. The path of the first air duct is "outdoor-outdoor", and an area of ​​the humidification wheel is set in the first air duct, so it can absorb moisture from the cold and humid air outdoors. The path of the second air duct is "outdoor-indoor", and the other part of the humidification wheel and the heating component are set in the second air duct. When the hot air passes through the humidification wheel, it takes away the moisture adsorbed on the humidification wheel and pours it into the room to humidify the indoor environment. The existing waterless humidification device is equipped with two independent air ducts, with two air inlets and two air outlets, and requires two fans to provide airflow power. This structure leads to high costs and a large volume of the entire device.

[0024] In order to improve at least one of the shortcomings of the above-mentioned prior art, an embodiment of the present application provides a waterless humidification device. By using a diverter plate, the airflow sent out by a fan is divided into two paths, which pass through different areas of the humidification wheel. Finally, one airflow is dehumidified and sent to the outside, and the other airflow is sent into the room with moisture for humidification. The waterless humidification device of the embodiment of the present application eliminates a fan, has a lower cost, and a more compact structure. While ensuring the humidification effect, it promotes the miniaturization of waterless humidification and can be installed on the indoor unit of a wall-mounted air conditioner. The embodiment of the present application also provides an air conditioner, which includes the waterless humidification device provided by the embodiment of the present application.

[0025] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the assembly of a waterless humidification device 100 in one embodiment of the present application; Figure 2 This is an exploded schematic diagram of a waterless humidification device 100 in one embodiment of the present application; Figure 3 1 is a cross-sectional view of a waterless humidification device 100 in one embodiment of the present application. Figures 1 to 3As shown, the waterless humidification device 100 includes a housing assembly, a fan 121, a heating assembly 142, a humidifying rotor 141, and a drive 160. An air duct is formed within the housing assembly, comprising an air inlet 111, an indoor air outlet 152, and an outdoor air outlet 151, all connected to the air duct. The fan 121, heating assembly 142, and humidifying rotor 141 are all located within the air duct. The fan 121 provides power, allowing air to enter through the air inlet 111 and exit through the indoor air outlet 152 and the outdoor air outlet 151. In use, the air inlet 111 connects to the outside, allowing fresh air with a certain humidity to enter. The outdoor air outlet 151 also connects to the outside, and the air exiting the outdoor air outlet 151 is air dehumidified by the humidifying rotor 141. The indoor air outlet 152 connects to the inside, and the air exiting the indoor air outlet 152 is humid air that has been dehumidified from the humidifying rotor 141.

[0027] The following describes the structure and working principle of each part along the direction of airflow. It should be understood that the directional descriptions such as "upstream" and "downstream" mentioned in the embodiments of this application are based on the direction of airflow under normal working conditions, with the direction of airflow being the upstream direction and the direction of airflow being the downstream direction.

[0028] In an embodiment of the present application, along the direction of air flow from upstream to downstream, the housing assembly includes, in sequence, an air collecting box 110, a volute 120, a runner housing 140, and a runner end cover 150 connected to the runner housing 140. The air collecting box 110, the volute 120, and the runner housing 140 are connected in sequence, the filter assembly (not shown in the figure) is arranged in the air collecting box 110, the fan 121 is arranged in the volute 120, and the humidifying wheel 141 is arranged in the runner housing 140. In this embodiment, the air inlet 111 is arranged in the air collecting box 110. Since the outdoor fresh air is to be introduced into the room through the waterless humidification device 100, the air collecting box 110 and the filter assembly are provided to filter and clean the incoming air to avoid the situation where the outdoor fresh air pollutes the indoor environment in a harsh environment. Fresh, moist air from outside enters the air collection box 110 through the air inlet 111. As it flows through the air collection box 110, it is filtered by the filter assembly within the air collection box 110, removing particulate matter and / or harmful components from the air. This is particularly useful in areas with severe haze and poor air quality. The filter assembly can include a filter, such as a HEPA filter, or other adsorbent materials, such as activated carbon.

[0029] After the airflow passes through the air collecting box 110, it will enter the volute 120. The chamber of the volute 120 is used to accommodate the fan 121, and the fan 121 is also the power source of the airflow in the entire air duct. In this embodiment, the fan 121 is a centrifugal fan. The centrifugal fan has the characteristics of axial air inlet and radial air outlet. Therefore, the upstream air collecting box 110 is arranged on the axial side of the volute 120, and the downstream impeller housing 140 is arranged on the radial side of the volute 120. Of course, in other optional embodiments, the selection of the fan 121 is not limited to a centrifugal fan, and can also be a cross-flow fan, an axial flow fan, etc., and should be based on the ability to provide power for the airflow in the air duct.

[0030] In the embodiment of the present application, a diverter plate 131 is provided in the air duct downstream of the fan 121 along the air flow direction. The diverter plate 131 is used to divide the airflow delivered by the fan 121 into a first air path and a second air path, and then enter the rotor housing 140. The first air path will subsequently provide moisture to the humidification rotor 141, and the second air path will subsequently remove moisture from the humidification rotor 141. In this embodiment, the volute 120 has a volute outlet portion 130, and the inner cavity of the volute 120 is connected to the rotor housing 140 through the volute outlet portion 130. The airflow delivered radially by the centrifugal fan 121 first passes through the volute outlet portion 130 and then flows into the chamber of the rotor housing 140, and at least a portion of the diverter plate 131 is located in the volute outlet portion 130. Because the humidifying wheel 141 is accommodated in the wheel shell 140, and the wheel shell 140 receives the airflow from the volute outlet 130, the diverter plate 131 is set at the volute outlet 130, so that the airflow entering the wheel shell 140 is divided into two paths, passing through different areas of the humidifying wheel 141 respectively, and the diverter plate 131 will not occupy too much space in the wheel shell 140 (this part of the space can be used to accommodate the humidifying wheel 141 and the heating component 142 as much as possible), making the overall structure more compact.

[0031] In this embodiment, the volute 120 has a tongue 122, which is a tongue-like structure formed at the connection between the volute outlet 130 and the main body of the volute 120 (the portion that houses the fan 121). The upstream end of the diverter plate 131 is located downstream of the tongue 122. By positioning the upstream end of the diverter plate 131 downstream of the tongue 122, the diverter plate 131 is prevented from being too close to the center of the fan chamber and affecting the air output of the fan 121.

[0032] Figure 3The hollow arrows indicate the path and direction of the airflow after it is divided into the first and second air paths. The first air path is delivered from the outdoor air outlet 151, and the second air path is delivered from the indoor air outlet 152. The humidifying rotor 141 is disposed downstream of the diverter plate 131. A portion of the humidifying rotor 141 is located in the first air path, and another portion is located in the second air path. The heating assembly 142 is located in the second air path between the humidifying rotor 141 and the diverter plate 131. The driving member 160 is used to drive the humidifying rotor 141 to rotate. The humidifying rotor 141 is used to absorb moisture from the first air path and supply moisture to the second air path. In this embodiment, the upstream end of the diverter plate 131 is located within the volute outlet 130, and the downstream end of the diverter plate 131 extends into the rotor housing 140. The heating assembly 142 is disposed within the rotor housing 140, and one side of the diverter plate 131 faces the heating assembly 142. In this embodiment, the downstream end of the diverter plate 131 extends into the rotor housing 140 to enhance the diversion effect, prevent the first and second air paths from rejoining after entering the rotor housing 140, and ensure that the air flows to different areas of the humidification rotor 141. One side of the diverter plate 131 faces the heating assembly 142, and the airflow separated by this side belongs to the second air path. The airflow in this air path will be heated by the heating assembly 142. The airflow with a higher temperature has a higher saturated vapor pressure and can therefore remove moisture from the wet humidification rotor 141. The airflow on the other side faces away from the heating assembly 142 and belongs to the first air path. It will not be heated by the heating assembly 142. The cold air has a lower saturated vapor pressure. Therefore, the moisture in the air in the first air path tends to (or is) saturated, making it easier for the humidification rotor 141 to adsorb it.

[0033] It can be seen that in the embodiment of the present application, a diverter plate 131 is used to divert the airflow generated by a fan 121, thereby forming a first air path and a second air path. The first air path is used to provide moisture to the humidification wheel 141, and the second air path is used to bring the moisture in the humidification wheel 141 into the room. The use of the diverter plate 131 realizes the formation of two air paths through one fan 121, thereby reducing costs. On the other hand, because the waterless humidification device 100 reduces the number of fans 121, the position of the fan 121 and the upstream air duct of the fan 121 do not need to be divided into two isolated air ducts. Since the overall structure is more compact and stable, the miniaturization of the entire waterless humidification structure is promoted.

[0034] In this embodiment, the downstream end of the diverter plate 131 is bent toward the side where the heating assembly 142 is located. By bending the downstream end of the diverter plate 131 toward the side of the heating assembly 142, this embodiment facilitates the second air path to pass through the heating assembly 142 and be fully heated by the heating assembly 142. Optionally, the diverter plate 131 may be arc-shaped at the downstream end; or it may be a broken line that forms a certain angle with its main body. In this embodiment, the heating assembly 142 may include heating wires. The second air path passes through the gaps between the heating wires of the heating assembly 142 and is thereby heated.

[0035] Furthermore, the cross-sectional areas of the first air path and the second air path at the volute outlet 130 are the same. In this embodiment, the cross-sectional areas of the first air path and the second air path at the volute outlet 130 are determined by the location of the diverter plate 131. Figure 3 As shown, the diverter plate 131 of this embodiment is positioned in the middle, approximately equidistant from the left and right inner walls. The identical cross-sectional areas of the first and second air paths at the volute outlet 130 mean that the gas flow rates of the two air paths are approximately equal, which helps balance the moisture absorption and humidification of the humidification wheel 141. It should be understood that in other optional embodiments, the position of the diverter plate 131 can also be adjusted according to specific circumstances, for example, to make the gas flow rate of the first air path greater or less than that of the second air path.

[0036] In this embodiment, the axis of the fan 121 is perpendicular to the axis of the humidifying wheel 141. One end face of the humidifying wheel 141 in the axial direction is the windward side, and the other end face opposite thereto is the leeward side. Figure 3 The upper surface is the windward surface, and the lower surface is the leeward surface. Both the first air path and the second air path flow from the windward surface of the humidifying wheel 141 to the leeward surface. In this embodiment, the spatial area where the first air path and the humidifying wheel 141 intersect can be regarded as a moisture absorption area, where the humidifying wheel 141 absorbs moisture from the airflow of the first air path; the spatial area where the second air path and the humidifying wheel 141 intersect can be regarded as a humidifying area, where the humidifying wheel 141 discharges the moisture absorbed from the moisture absorption area into the second air path in the humidifying area, thereby humidifying the second air path and forming a humid and hot air flow that is discharged into the room. The reason why the humidifying wheel 141 can absorb moisture from the first air path and humidify the second air path with the same humidity is that the first air path is not heated by the heating component 142, while the second air path is heated to a higher temperature (for example, 80 to 90 degrees Celsius) by the heating component 142, and the saturated vapor pressure in the first air path is lower than the saturated vapor pressure in the second air path. At the same humidity, the water vapor partial pressure in the gas in the first air path is closer to (or equal to) the saturated vapor pressure, and is easily absorbed by the humidification wheel 141, while the water vapor partial pressure in the second air path is far from the saturated vapor pressure at that temperature. Therefore, it has a stronger ability to absorb moisture from the outside and will absorb moisture from the moistened humidification wheel 141.

[0037] In this embodiment, the end of the impeller housing 140 away from the volute 120 has an opening, and the impeller end cover 150 is arranged at the opening. The indoor air outlet 152 and the outdoor air outlet 151 are both arranged at the impeller end cover 150. Specifically, the impeller end cover 150 is connected to the impeller housing 140 by a snap-fit ​​structure for easy assembly and disassembly. The first air path is delivered from the outdoor air outlet 151, which is arranged on the outer peripheral side of the impeller end cover 150, specifically facing upward (see FIG. Figure 1 and Figure 2 and the second air duct is delivered from the indoor air outlet 152, the indoor air outlet 152 is provided on the end surface of the rotor end cover 150, axially opposite to the humidifying rotor 141, toward the bottom (see Figure 3 It should be understood that in other optional embodiments, the locations of the indoor air outlet 152 and the outdoor air outlet 151 can be adjusted according to specific circumstances, but should be located on the leeward side of the humidifying wheel 141.

[0038] Furthermore, in this embodiment, a driving member 160 is provided on the rotor end cover 150. The driving member 160 is used to drive the humidification rotor 141 to rotate. Specifically, the driving member 160 is connected to the teeth on the outer peripheral side of the humidification rotor 141 through a gear to drive the humidification rotor 141 to rotate at a certain speed. When the humidification rotor 141 rotates continuously, it can continuously absorb moisture from the first air path, and then transfer the wet part from the first air path to the second air path, and supply the absorbed moisture to the air flow of the second air path, thereby realizing the simultaneous moisture absorption and humidification processes. Optionally, the driving member 160 can be a stepping motor.

[0039] In an optional embodiment of the present application, a portion of the volute 120 and a portion of the impeller shell 140 are integrally connected to form a first integrated cover 101, and another portion of the volute 120 and another portion of the impeller shell 140 are integrally connected to form a second integrated cover 102. The diverter plate 131 is provided on the first integrated cover 101, and the diverter plate 131 abuts against the inner wall of the second integrated cover 102 after the first integrated cover 101 and the second integrated cover 102 are assembled. In this embodiment, the diverter plate 131 is provided on the inner side of the first integrated cover 101, and the other side abuts against the second integrated cover 102 in the assembled state. This arrangement does not form a seam in the middle of the volute outlet portion 130, and the diversion effect is better. In this embodiment, the volute outlet portion 130 is divided into two parts, one part is integrated into the first integrated cover 101, and the other part is integrated into the second integrated cover 102. The diverter plate 131 is provided at the portion of the volute outlet portion 130 located in the first integrated cover 101.

[0040] In an optional embodiment, a portion or the entirety of the air collecting box 110 may also be integrated into the first integrated cover 101 or the second integrated cover 102, and integrally connected to a portion of the volute 120 and / or a portion of the runner housing 140. It should be understood that in this embodiment, the integral connection refers to a connection as a whole that cannot be detached, and may be achieved by bonding, welding, casting, injection molding, or by bending or stamping sheet metal parts.

[0041] Figure 4 FIG. 1 is a schematic diagram of an air conditioner 010 in one embodiment of the present application. Figure 4 As shown, the embodiment of the present application also provides an air conditioner 010, including an air conditioner main body 200 and a waterless humidifying device 100 provided in the above embodiment of the present application. The air conditioner main body 200 includes components such as a heat exchange component and an air outlet component for realizing basic temperature control functions, and the waterless humidifying device 100 is used to humidify the room. The waterless humidifying device 100 provided in the embodiment of the present application does not require manual water addition, and the moisture comes from the outdoor air, so it can realize the "waterless humidification" function. A decorative panel can be provided on the outside of the waterless humidifying device 100 to make it uniform with the appearance of the air conditioner main body 200 and more beautiful. The air conditioner 010 can be a wall-mounted indoor air conditioner, a cabinet air conditioner, or other types of air conditioning systems.

[0042] In this embodiment, since the airflow discharged into the room by the waterless humidifying device 100 is humid and hot airflow, it is more suitable to be activated simultaneously with the heating function of the air-conditioning body 200 at low temperatures. The heat provided by the heating component 142 of the waterless humidifying device 100 can be used for heating the user.

[0043] In summary, in the waterless humidification device 100 of the embodiment of the present application, a diverter plate 131 is used to divert the airflow generated by a fan 121, thereby forming a first air path and a second air path. The first air path is used to provide moisture to the humidification wheel 141, and the second air path is used to bring the moisture in the humidification wheel 141 into the room. By using the diverter plate 131, two air paths are formed through one fan 121, thereby reducing costs. On the other hand, because the waterless humidification device 100 reduces the number of fans 121, the position of the fan 121 and the upstream air duct of the fan 121 do not need to be divided into two isolated air ducts, so the overall structure is more compact and stable. The air conditioner 010 provided in the embodiment of the present application includes the above-mentioned waterless humidification device 100, so while having the waterless humidification function, it also has the characteristics of low cost and compact structure.

[0044] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims.
