[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The following is for reference. Figures 1-7 An air handling apparatus 200 according to an embodiment of the present invention is described.

[0041] like Figures 1-7 As shown, the air handling device 200 according to an embodiment of the present invention includes: a housing 10, a heating element 22, a baffle assembly 20 and a drive assembly 24. The housing 10 forms a first air duct 11 and a second air duct 12. The first air duct 11 is used for supplying air and the second air duct 12 is used for exhausting air, thereby realizing air circulation.

[0042] Heating element 22 is disposed in the first air duct 11 for heating outdoor air; baffle assembly 20 is disposed in the first air duct 11, baffle assembly 20 includes baffle 21 and valve plate 23, baffle 21 defines an air outlet 213, and valve plate 23 is disposed on one side of baffle 21; drive assembly 24 is disposed in housing 10, and drive assembly 24 cooperates with valve plate 23 so that drive assembly 24 can drive valve plate 23 to move to block part of air outlet 213. It can be understood that by the movement of valve plate 23, the blocked part of air outlet 213 can be changed, thereby changing the flow path in the first air duct 11.

[0043] According to an embodiment of the present invention, the air handling device 200 drives the valve plate 23 to move via the drive component 24, so that the valve plate 23 can block a part of the air outlet 213, thereby dividing the air outlet 213 into multiple areas. Multiple flow paths can be formed in the first air duct. The multiple flow paths cooperate with each other, which can expand the air supply working mode of the air handling device 200. It is not necessary to set multiple air outlets 213 on the baffle 21, which is convenient for processing and manufacturing. Furthermore, the heating element 22 is cooperated with one flow path to allow hot air to enter, so that the other flow paths can achieve the function of side ventilation of the heating element 22, thereby increasing the air supply volume. Compared with the air inlet where the heating element fills the entire air duct, it can also reduce energy waste.

[0044] like Figure 1 As shown, in some examples, a dividing baffle 13 is provided inside the housing 10, which can divide the space inside the housing 10 into a first air duct 11 and a second air duct 12. The first air duct 11 and the second air duct 12 do not interfere with each other, so that the air intake function and the air exhaust function of the air handling equipment 200 do not interfere with each other, which can improve the air exchange efficiency of the air handling equipment 200.

[0045] like Figure 2 , Figure 5 and Figure 7 As shown, in some examples, the first air duct 11 has a first flow path 111 and a second flow path 112, and the air outlet 213 includes a first region 211 and a second region 212. The position of the first region 211 corresponds to the position of the heating element 22 and is located on the first flow path 111. Air heated by the heating element 22 can flow through the first flow path 111.

[0046] When the drive assembly 24 drives the valve plate 23 to move to a certain position, the valve plate 23 can block a part of the second region 212, so that the other part of the second region 212 can also be connected to the outside. The other part of the second region 212 is located in the second flow path 112, which can supplement the air volume of the first flow path 111.

[0047] When the drive assembly 24 drives the valve plate 23 to move in the opposite direction to another position, the valve plate 23 can block another part of the second region 212, so that a part of the second region 212 can be connected to the outside. A part of the second region 212 is located on the third flow path 113, which can supplement the air volume of the first flow path 111.

[0048] It is understandable that the second flow path 112 and the third flow path 113 have low air resistance due to the absence of heating elements, which can compensate for the ventilation volume of the first flow path 111, thereby increasing the ventilation volume of the first air duct 11 and improving the air circulation efficiency of the air handling equipment 200.

[0049] like Figure 5 and Figure 7 As shown, in some examples, the second flow path 112 can be located above the first flow path 111, and the third flow path 113 can be located between the first flow path 111 and the second flow path 112. It should be noted that the sum of the portion of the air outlet 213 corresponding to the second flow path 112 and the portion of the air outlet 213 corresponding to the third flow path 113 is less than the second region 212. That is, when the valve plate 23 is active, a portion of the second region 212 is always blocked. Of course, the size of the portion of the air outlet 213 corresponding to the second flow path 112 should be as large as possible, and the size of the portion of the air outlet 213 corresponding to the third flow path 113 should also be as large as possible. While ensuring the performance of the air handling equipment 200, the speed of the fan in the duct can be reduced, saving energy consumption. At the same time, the overall noise can be reduced, and the user experience can be improved.

[0050] like Figure 2 As shown, according to some embodiments of the present invention, the drive assembly 24 includes a motor 241 and a drive rod 242. The motor 241 is connected to the drive rod 242 and can drive the drive rod 242 to rotate. The drive rod 242 cooperates with the valve plate 23 to drive the valve plate 23 to move. Specifically, with the other end of the drive rod 242 as the center point, the entire drive rod 242 can make a circular motion around the center point. That is, the motor 241 can drive one end of the drive rod 242 to rotate upward or downward in a circular motion. The drive rod 242 applies pressure or tension to the valve plate 23, thereby driving the valve plate 23 to move up and down, which can improve the smoothness of the movement of the valve plate 23.

[0051] It should be noted that the drive assembly 24 can be set at the upper end of the valve plate 23 or at the lower end of the valve plate 23. The drive assembly 24 may include two sets set at the upper and lower ends of the valve plate 23. Under the action of the two drive assemblies 24, the valve plate 23 can be moved stably and reliably, and the assembly is convenient.

[0052] like Figure 2 , Figure 4 and Figure 6 As shown, in some examples, the air handling unit 200 also includes a reset member 90, which can be connected to the valve plate 23. The reset member 90 can drive the valve plate 23 to move in the opposite direction. It should be noted that the reverse movement here refers to the direction opposite to the direction of movement of the valve plate 23 when the drive rod 242 applies an external force to the valve plate 23. It can be understood that even though the external force applied to the valve plate 23 is removed, the valve plate 23 can abut against the side of the drive rod 242 when the valve plate 23 moves in the opposite direction.

[0053] In some examples, the valve plate 23 has a first flange 231 and a second flange 232, which are located between the drive rod 242 and the reset member 90. The first flange 231 and the second flange 232 are arranged at intervals. The drive rod 242 cooperates with the first flange 231 to push the valve plate 23 to move forward, and the reset member 90 cooperates with the second flange 232 to drag the valve plate 23 to move in the opposite direction. The drive rod 242 and the reset member 90 cooperate with each other to facilitate the control of the movement direction of the valve plate 23 to block different flow paths. It should be noted that the side of the valve plate 23 facing away from the baffle 21 (e.g. Figure 2 The front side shown is provided with a first flange 231 and a second flange 232. The first flange 231 is located at the upper end of the valve plate 23, so that one end of the drive rod 242 can abut against the first flange 231. The second flange 232 is located at the lower end of the valve plate 23, so that one end of the reset member 90 can abut against the second flange 232.

[0054] In some specific examples, the drive rod 242 is positioned above the valve plate, and the reset member 90 is positioned below the valve plate. The motor drives the drive rod 242 to rotate, and the drive rod 242 can apply downward pressure to the first flange 231 of the valve plate 23, causing the valve plate 23 to move downward. At this time, the reset member 90 is deformed and compressed. When the motor 241 drives the drive rod 242 to rotate in the opposite direction, the pressure on the first flange 231 is removed, the drive rod 242 can disengage from the first flange 231, the reset member 90 is reset, and the valve plate 23 moves upward.

[0055] Of course, the motor 241 and the drive rod 242 can also drive the valve plate 23 to move upward. When the external force of the drive rod 242 on the first flange 231 is removed, the reset member 90 can drive the valve plate 23 to move downward.

[0056] like Figure 2 As shown, in some examples, the valve plate 23 also has a second flange 232, which is spaced apart from the first flange 231, and the reset member 90 is disposed on the side of the second flange 232 opposite to the first flange 231 (e.g. Figure 2(as shown on the lower side), and the reset member 90 is connected to the second flange 232. This connection can be an abutment connection or a fixed connection. By setting the second flange 232, it is convenient for the reset member 90 to cooperate with the valve plate 23, thereby driving the valve plate 23 to move in the opposite direction. It can be understood that if the first flange 231 is set on the upper side of the valve plate 23, then the second flange 232 is set on the lower side of the valve plate 23, and if the first flange 231 is set on the lower side of the valve plate 23, then the second flange 232 is set on the upper side of the valve plate 23.

[0057] like Figure 4 and 6 As shown, in some examples, the reset member 90 can be a spring or a accumulator or other structural component that can store and release energy. When the valve plate 23 moves toward the position of the reset member 90, the reset member 90 is compressed to store energy. When the drive rod 242 disengages from the valve plate 23, the reset member 90 releases energy and extends itself to move the valve plate 23 toward the position of the drive rod 242. Of course, the energy storage method of the reset member 90 can also be through stretching.

[0058] like Figure 2 As shown, in some specific examples, the valve plate 23 is disposed on the side of the baffle 21 near the heating element 22 (e.g. Figure 2 (As shown in the front side), the valve plate 23 is located above the heating element 22, and the drive assembly 24 is located above the valve plate 23; the reset element 90 is located below the valve plate 23, and the lower end of the reset element 90 is connected to the heating element 22, and the upper end of the reset element 90 is connected to the second flange 232. That is, the reset element 90 is sandwiched between the valve plate 23 and the heating element 22, which can reduce the size of the reset element 90, facilitate the force storage deformation and reset of the reset element 90, make the movement of the valve plate 23 more stable, and at the same time, the arrangement is reasonable, the structure is compact, and the space above the heating element 22 is fully utilized.

[0059] like Figure 2 As shown, according to some embodiments of the present invention, the valve plate 23 has a guide rail 25 and the baffle 21 has a mating part, or the valve plate 23 has a mating part and the baffle 21 has a guide rail 25. The mating part can be inserted into the guide rail 25 and the mating part slides with the guide rail 25, so that the valve plate 23 can always move along the extension direction of the guide rail 25, thereby improving the smoothness of the operation of the valve plate 23 and improving the reliability of the drive assembly 24.

[0060] In some examples, the mating parts can be snap-fit ​​or ball bearings. That is, the valve plate 23 can be snapped into the guide rail 25 to prevent the valve plate 23 from disengaging from the baffle 21. The valve plate 23 can also be mated with the guide rail 25 by ball bearings to reduce friction, while facilitating assembly, reducing costs, and making it easy to promote and apply.

[0061] like Figures 1-7As shown, according to some embodiments of the present invention, the air handling equipment 200 further includes: a rotor assembly 100, which is rotatably disposed within the housing 10 and distributed in two air ducts. A portion of the rotor assembly 100 is located in the first air duct 11, and another portion of the rotor assembly 100 is located in the second air duct 12. The rotor assembly 100 has an adsorbent that can adsorb and release moisture. For example, the material of the adsorbent can be silica gel, molecular sieve, etc. In this case, the adsorbent can adsorb moisture in the air at low temperature to dry the air, and the adsorbent can release moisture at high temperature to humidify the air, thereby eliminating the need for additional water tank humidification or built-in compressor, saving production costs.

[0062] The baffle assembly 20 is disposed between the heating element 22 and the rotating wheel assembly 100. The air heated by the heating element 22 is passed to the rotating wheel assembly 100 through the first flow path 111, which can release the moisture adsorbed by the adsorbent and then send the high humidity air into the room through the first air duct 11 to improve the comfort of the room.

[0063] like Figure 3 , Figure 5 and Figure 7 As shown, in some examples, the rotor assembly 100 extends at an angle, with the portion of the rotor assembly 100 near the baffle 21 adjacent to the top of the housing 10, and the portion of the rotor assembly 100 away from the baffle 21 adjacent to the bottom of the housing 10. That is, along the front-to-back direction, the rotor assembly 100 is tilted downward. By tilting the rotor assembly 100, the thickness space occupied can be reduced, that is, the overall size of the machine in the vertical direction can be reduced, improving the aesthetics of the appearance, while facilitating the installation and use of the air handling equipment 200 in different situations.

[0064] It is understandable that by tilting the rotary assembly 100, the air flowing in the first flow path 111 and the third flow path 113 can both pass through the rotary assembly 100, and the air heated by the heating element 22 can fully contact the adsorption element, thereby improving the humidification effect of the rotary assembly 100 on the outside air.

[0065] like Figure 3 , Figure 5 and Figure 7 As shown, according to some embodiments of the present invention, the air handling equipment 200 further includes a rotary vane 80, which is disposed at the baffle 21, and the rotary vane 80 is oriented away from the baffle 21 (e.g., Figure 3 As shown in the rear direction, the airflow in the second flow path 112 is separated by the rotor partition 80 because the rotor assembly 100 is inclined downward in the direction away from the baffle 21. It does not need to pass through the rotor assembly 100, which reduces the airflow resistance, increases the air volume, and improves the user experience.

[0066] like Figure 4 and Figure 5 As shown, in some examples, the valve plate 23 can move between a first position and a second position. In the first position, the valve plate 23 blocks the middle of the air passage 213, and the upper edge of the valve plate 23 is higher than the rotary partition 80. At this time, the lower part of the air passage 213 can communicate with the outside, and the upper part of the air passage 213 can communicate with the outside. The upper part of the air passage 213 can supplement the ventilation volume in one working mode of the air handling equipment 200. By setting the upper edge of the valve plate 23 higher than the rotary partition 80, the upper air of the air passage 213 can be prevented from flowing to other parts, thus achieving the function of preventing air leakage.

[0067] like Figure 6 and Figure 7 As shown, when the valve plate 23 moves to the second position, the valve plate 23 blocks the upper part of the air passage 213, and the lower edge of the valve plate 23 is lower than the rotary partition 80. At this time, the lower part of the air passage 213 can communicate with the outside, and the middle part of the air passage 213 can communicate with the outside. The middle part of the air passage 213 can supplement the ventilation volume in another working mode of the air handling equipment 200. By setting the lower edge of the valve plate 23 lower than the rotary partition 80, the air in the middle of the air passage 213 can be prevented from flowing to other parts, thus achieving the function of air leakage.

[0068] like Figure 1 As shown, in some examples, the housing 10 has a first air inlet 51, a first air outlet 52, a second air inlet 53, and a second air outlet 54. A first air duct 11 is formed between the first air inlet 51 and the first air outlet 52, and a second air duct 12 is formed between the second air inlet 53 and the second air outlet 54. The first air inlet 51 and the second air outlet 54 are simultaneously located at one end of the air handling unit 200 (e.g., ...). Figure 1 As shown in the front end), the first air outlet 52 and the second air inlet 53 are simultaneously located at the other end of the air handling unit 200 (e.g., the front end). Figure 1 As shown at the rear end), the first air inlet 51 can introduce outdoor air into the first air duct 11, the first air outlet 52 can introduce air from the first air duct 11 into the room, the second air inlet 53 can introduce indoor air into the second air duct 12, and the second air outlet 54 can introduce air from the second air duct 12 into the outside, thereby realizing the ventilation function of the air handling equipment 200.

[0069] like Figure 1 As shown, in some examples, the air handling unit 200 further includes a purification component 30, which is disposed within the first air duct 11 and located upstream of the heating element 22 (e.g., Figure 1 (As shown in the front), the purification component 30 can purify the outside air and then introduce it into the room.

[0070] The purification component 30 includes a first filter element 31 and a second filter element 32. The first filter element 31 is located in front of the second filter element 32. The second filter element 32 and the first filter element 31 can filter different impurities respectively. The second filter element 32 and the first filter element 31 work together to improve the purification effect of the purification component 30.

[0071] Of course, the air handling unit 200 also includes a third filter element 33, which can be disposed within the second air duct 12 and located upstream of the second air duct 12 (e.g., Figure 1 (As shown at the rear), by setting a third filter 33, the air exhausted from the room can be filtered and cleaned to prevent dust and other particles from entering the second air duct 12, maintain the cleanliness of the second air duct 12, facilitate maintenance, and reduce maintenance costs.

[0072] like Figure 1 As shown, in some examples, the air handling unit 200 further includes a first fan 70 and a second fan 71. The first fan 70 is located at the rear end of the first air duct 11 and is arranged opposite to the purification component 30. The second fan 71 is located at the front end of the second air duct 12 and is arranged opposite to the third filter element 33, ensuring that air is introduced into the housing 10 after the filter element is cleaned, thereby improving the service life of the air handling unit 200.

[0073] like Figure 1 As shown, in some examples, the air handling unit 200 further includes a controller 60, which can be disposed outside the housing 10. The controller 60 can control the operating status of the air handling unit 200 according to the user's needs. The controller 60 can control the operation of the drive assembly 24 and the rotary drive component 40. By controlling the operation of the drive assembly 24, the drive assembly 24 can drive the valve plate 23 to flip, opening and closing the second air outlet 213 and the third air outlet 213. By controlling the rotary drive component 40, the rotary drive component 40 can drive the rotary assembly 100 to rotate. After the part of the adsorption component located in the first air duct 11 releases moisture, it can rotate to the second air duct 12 to absorb the moisture in the second air duct 12. This allows the rotary assembly 100 to be reused, saving production costs while ensuring the humidification performance of the air handling unit 200.

[0074] like Figures 4-7As shown, in some examples, the air handling unit 200 includes a first operating mode and a second operating mode. In the first operating mode, the heating element 22 is working, and the valve plate 23 moves to block the lower part of the second area 212. At this time, the heated air can be introduced into the room through the first flow path 111. The heated air can cause the adsorbent to release moisture, thereby introducing the humidified air into the room. The second flow path 112 can replenish the filtered air and improve the fresh air supply effect.

[0075] In the second working mode, the valve plate 23 moves to block the upper part of the second area 212. At this time, outside air can enter the room through the first flow path 111, while the third flow path 113 can replenish the filtered air. The air in the two flow paths can use the heat on the wheel assembly 100 to heat the outside air before it is introduced into the room, thereby increasing the air supply temperature. This eliminates the need for the heating element 22 to work, saving energy, reducing operating costs, and improving the user experience.

[0076] like Figures 1-7 As shown, according to some specific embodiments of the present invention, the air handling equipment 200 includes: a housing 10, a dividing baffle 13, a baffle assembly 20, a reset member 90, and a rotary wheel assembly 100. A controller 60 is disposed outside the housing 10. The dividing baffle 13 divides the internal space of the housing 10 into a first air duct 11 and a second air duct 12. A heating element 22, a purification assembly 30, a baffle assembly 20, and a first fan 70 are disposed in the first air duct 11. A third filter element 33 and a second fan 71 are disposed in the second air duct 12. The purification assembly 30 and the heating element 22 are disposed at the front end of the first air duct 11, the heating element 22 is located behind the purification assembly 30, the first fan 70 is located at the rear end of the first air duct 11, the second fan 71 is located at the front end of the second air duct 12, and the third filter element 33 is located at the rear end of the second air duct 12.

[0077] The rotor assembly 100 is disposed between the first air duct 11 and the second air duct 12, and is located in the middle of the air handling unit 200. The baffle assembly 20 is disposed between the heating element 22 and the rotor assembly 100. The baffle assembly 20 includes a baffle 21, a valve plate 23, and a drive assembly 24. The baffle 21 defines an air passage 213, which includes a first region 211 and a second region 212, with the second region 212 located above the first region 211. The valve plate 23 is movably disposed on the baffle 21 and can block the second region 212. In a portion of region 212, a drive assembly 24 is disposed on the upper side of valve plate 23, and the drive assembly 24 includes a motor 241 and a drive rod 242. The motor 241 drives the drive rod 242 to rotate. One end of the drive rod 242 can abut against valve plate 23, so that the drive rod 242 can cooperate with valve plate 23 to drive valve plate 23 to move. A reset member 90 is disposed on the lower side of valve plate 23, and the reset member 90 is sandwiched between valve plate 23 and heating member 22, and can cooperate with drive assembly 24 to make valve plate 23 move in the opposite direction.

[0078] like Figure 4 and Figure 5 As shown, the first working mode is the humidification mode. In the first working mode, the controller 60 controls the drive assembly 24 and the rotary drive component 40 to work. The motor 241 in the drive assembly 24 controls the drive rod 242 to rotate downward. The drive rod 242 abuts against the valve plate 23 to drive the valve plate 23 to move downward, thereby blocking the lower part of the second area 212. At this time, since the lower end of the reset component 90 is fixed on the heating element 22, the reset component 90 is compressed by the valve plate 23, and the reset component 90 stores energy. The rotary drive component 40 controls the rotary assembly 100 to rotate the rotary assembly 100. The first fan 70 works, and outdoor air is first introduced. The air enters the first air duct 11 through the first air inlet 51, and then passes through the purification component 30. The purified air is divided into two airflows at the front end of the heating element 22. One part of the air is heated by the heating element 22 and then passes through the first flow path 111. When the heated air passes through the rotating wheel assembly 100, it absorbs the moisture in the adsorption element and carries the moisture to the rear of the first air duct 11. The other part of the air passes directly through the second flow path 112 and flows from the top of the rotating wheel assembly 100 to the rear of the first air duct 11. The two parts of the air flow to the rear of the first air duct 11, pass through the first fan 70, and then enter the room through the first air outlet 52.

[0079] Meanwhile, indoor air first enters the second air duct 12 through the second air inlet 53, then passes through the third filter 33, and reaches the rotor assembly 100. At this time, the adsorbent that releases moisture in the first air duct 11 rotates into the second air duct 12 under the action of the rotor drive 40. When the air in the second air duct 12 passes through the adsorbent, the moisture is absorbed by the adsorbent, and then it is introduced into the outside through the second air outlet 54 by the second fan 71. The air forms a circulation in the air handling equipment 200, thereby realizing the fresh air exchange function of the air handling equipment 200 and continuously humidifying the indoor air.

[0080] like Figure 6 and Figure 7 As shown, the second working mode is the heat recovery mode. In the second working mode, the heating element 22 stops working, and the controller 60 controls the drive assembly 24 and the rotary drive 40 to work. The motor 241 in the drive assembly 24 controls the valve plate 23 to rotate upward. At this time, the drive rod 242 disengages from the valve plate 23 and does not apply pressure to the valve plate 23 or the reset member 90. The reset member 90 releases the stored energy and resets by extending. Since the lower end of the reset member 90 is fixed on the heating element 22, the reset member 90 can drive the valve plate 23 to move upward, so that the valve plate 23 blocks the upper part of the second area 212. The rotary drive 40 controls the rotary assembly 100 to rotate the rotary assembly 100. The first fan 70 works, and the outdoor air first enters the first air duct 11 through the first air inlet 51, and then passes through the purification assembly 30 to reach the front end of the baffle assembly 20 and the heating element 22 (e.g., Figure 1 As shown in the front end), the purified air is divided into two airflows at the front end of the heating element 22. One part of the air passes through the first flow path 111, and the other part passes through the third flow path 113. The two parts of the air merge together and pass through the rotor assembly 100. At this time, the heat on the rotor assembly 100 can be carried away, so that the air is heated and enters the room from the first air outlet 52.

[0081] Meanwhile, indoor air first enters the second air duct 12 through the second air inlet 53, then passes through the third filter 33, and reaches the rotor assembly 100. At this time, the heat in the second air duct 12 is absorbed by the rotor assembly 100. After passing through the rotor assembly 100, the air is discharged by the second fan 71. As the rotor assembly 100 rotates, when the part that has absorbed heat rotates into the first air duct 11, it is carried away by the low-temperature air in the first air duct 11. This part of the rotor assembly 100 changes from a high-temperature rotor to a low-temperature rotor, and then enters the second air duct 12 again to absorb heat, and so on. In the second working mode, the heating element 22 does not need to work, making it more energy-efficient overall.
