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.

[0046] 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.

[0047] The following is for reference. Figures 1-11 A rotary wheel assembly 300 according to an embodiment of the present invention is described.

[0048] like Figures 1-11 As shown, a rotary wheel assembly 300 according to an embodiment of the present invention includes: a rotary wheel bracket 30, a rotary wheel body 40, and a support member 50. The rotary wheel bracket 30 has an installation space 31. The rotary wheel body 40 is rotatably disposed within the installation space 31. The support member 50 is disposed between the rotary wheel body 40 and the rotary wheel bracket 30. The support member 50 can abut against the rotary wheel body 40, thereby supporting the rotary wheel body 40 and making the rotary wheel body 40 rotate smoothly. This avoids problems such as eccentricity and misalignment during the assembly or operation of the rotary wheel body 40. It is understood that when the rotary wheel body 40 rotates, the rotary wheel body 40 can rotate relative to the support member 50 to ensure the normal operation of the rotary wheel body 40.

[0049] According to the embodiment of the present invention, the rotary wheel assembly 300, by circumferentially arranging support members 50 on the rotary wheel body 40, supports and limits the rotary wheel body 40 during rotation, making the rotary wheel body 40 rotate smoothly and avoiding problems such as eccentricity and misalignment during assembly or operation. Furthermore, the rotary wheel body 40 can rotate relative to the support members 50, preventing the support members 50 from affecting the rotation of the rotary wheel body 40, minimizing friction between the support members 50 and the rotary wheel body 40, ensuring the reliability of the rotary wheel body 40's operation, and thus facilitating its application in equipment, ensuring the equipment's internal sealing, and improving the user experience.

[0050] In some examples, multiple support members 50 are arranged at intervals along the circumference of the wheel body 40. The multiple support members 50 limit the wheel body 40 in the circumference of the wheel body 40 to avoid eccentricity when the wheel body 40 rotates. The wheel body 40 can move relative to the support members 50 to ensure the reliability of the rotation of the wheel body 40 and reduce friction at the support limit.

[0051] like Figure 6 As shown, according to some embodiments of the present invention, the support member 50 includes a support seat 51 and a first rolling member 52. The support seat 51 is disposed in the wheel bracket 30. Here, the support seat 51 can be fixedly connected to the wheel bracket 30 by fasteners, or it can be installed in the wheel bracket 30 by a support member bracket 60.

[0052] In some examples, the first rolling element 52 is mounted on the support 51 via the first fixed shaft 53. The first rolling element 52 is interference-fitted with the first fixed shaft 53, and abuts against the outer side of the wheel body 40. Thus, when the wheel body 40 rotates, the first rolling element 52 rotates as well, reducing friction at the limiting point, improving the smoothness of the wheel body 40's rotation, and preventing rotational jamming. Here, the first fixed shaft 53 can be a fixed structure fixed to the support 51, with the first rolling element 52 sleeved on the outside of the first fixed shaft 53; the first fixed shaft 53 can also be detachably connected to the support 51, for example, the first rolling element 52 can be a bearing, and the first fixed shaft 53 can be a fastener, such as a screw or bolt, which fixes the first rolling element 52 to the support 51.

[0053] It should be noted that the extension direction of the first fixed shaft 53 is the same as the direction of the rotation axis of the first rolling element 52. The first fixed shaft 53 can extend along the rotation axis of the wheel body 40, thereby allowing the first rolling element 52 and the wheel body 40 to rotate in the same plane. Of course, the extension direction of the first fixed shaft 53 can also be inclined relative to the rotation axis of the wheel body 40, with the outer surface of the wheel body 40 correspondingly inclined, so that the first rolling element 52 can still abut against the outer surface of the wheel body 40. The first rolling element 52 can provide a certain support for the wheel body 40, preventing the wheel body 40 from shaking or misaligning, thereby improving the limiting effect of the first rolling element 52 without affecting the rotation of the wheel body 40.

[0054] In some examples, the outer surface of the wheel body 40 has two opposing mating surfaces (e.g., upper and lower mating surfaces). Both mating surfaces extend obliquely relative to the plane on which the wheel body 40 is located. The first rolling element 52 can abut against either mating surface. That is, in the circumferential direction of the wheel body 40, the first rolling elements 52 of the multiple support elements 50 can all abut against the upper mating surface, or all abut against the lower mating surface, or a portion of the first rolling elements 52 abut against the upper mating surface and another portion of the first rolling elements 52 abut against the lower mating surface. This improves the limiting effect on the wheel body 40 and enhances the stability and reliability of the overall structure.

[0055] Furthermore, the rotation axis of the first rolling element 52 can be parallel to the arrangement direction of the wheel body 40. The outer side of the wheel body 40 has two mating surfaces parallel to the arrangement direction. The opposite sides of the first rolling element 52 simultaneously abut against the two mating surfaces, thereby achieving reliable support and limiting function and improving the stability of the wheel body 40 during rotation.

[0056] like Figure 3 and Figure 6 As shown, in some examples, the support member 50 includes a second rolling member 54, which is disposed on the support seat 50 and abuts against the wheel body 40. The second rolling member 54 can be a bearing. By providing two rolling members, the support effect of the support member 50 on the wheel body 40 can be improved, and the stability of the wheel body 40 during rotation can be improved.

[0057] In some examples, the second rolling element 54 is mounted on the support 51 via a second fixed shaft 55. The inner ring of the second rolling element 55 is interference-fitted with the second fixed shaft 55, and the outer ring of the second rolling element 54 abuts against the outer surface of the wheel body 40. Thus, when the wheel body 40 rotates, the second rolling element 54 rotates, reducing friction at the limiting point, improving the smoothness of the wheel body 40's rotation, and preventing rotational jamming. Here, the second fixed shaft 55 can be a fixed structure fixed to the support 51, with the second rolling element 54 sleeved on the outside of the second fixed shaft 55; alternatively, the second fixed shaft 55 can be detachably connected to the support 51, for example, by being a fastener that fixes the second rolling element 54 to the support 51.

[0058] In some specific examples, the first rolling element 52 and the second rolling element 54 are located on both sides of the first plane, which is perpendicular to the axis of the rotating body 40, thereby achieving support and limiting at different positions and improving the stability of the overall structure.

[0059] In some specific examples, the rotation axes of the first rolling element 52 and the second rolling element 54 are in different directions, that is, the extension direction of the second fixed shaft 55 is different from the extension direction of the first fixed shaft 53. The extension direction of each fixed shaft is inclined to the rotation direction of the wheel body 40. As a result, the rotation axes of the first rolling element 52 and the second rolling element 54 are both inclined to the rotation plane of the wheel body 40. The first rolling element 52 and the second rolling element 54 can limit the rotation of the wheel body 40 in two directions, further avoiding the eccentricity and misalignment problems caused by the rotation of the wheel body 40.

[0060] In some specific examples, the angle between the first rolling element and the first plane is α1, and the angle between the second rolling element and the first plane is α2, where α1 and α2 are the same. This allows the first rolling element and the second rolling element to exert symmetrical forces on the wheel body 40, thereby offsetting the axial external forces on the wheel body 40 and preventing the wheel body 40 from coming out of the wheel bracket.

[0061] In some examples, multiple support members are arranged circumferentially on the wheel body. The structures of the multiple support members 50 can be different. For example, some support members 50 have a first rolling element 52, and some support members 50 have a second rolling element 54. This can reduce the structural cost while satisfying the support and limiting effect. Of course, the structures of the multiple support members 50 can also be the same. For example, the support member 50 can be set to a structure with two rolling elements, so that multiple structural members that can realize bidirectional limiting are evenly arranged circumferentially on the wheel body 40, thereby improving the stability of the wheel body 40 in all directions.

[0062] In some specific examples, the circumferential axis of the rotor body 40 includes three support members 50, each with two rolling elements. The three support members 50 are evenly distributed along the outer circumference of the rotor body 40, and the six rolling elements on the three support members 50 form a circular track. The rotor body 40 rotates on the track formed by the six rolling elements, thereby avoiding the eccentricity and misalignment problems caused by the rotor body rotating around the central axis. Of course, the number of support members 50 is not limited to three; it can be four or even more.

[0063] like Figure 3 and Figure 8 As shown, in some examples, the outer surface of the wheel body 40 is provided with an inwardly recessed groove 411. A portion of the support member 50 can be inserted into the groove 411. The first rolling member 52 can abut against one inner wall surface of the groove 411, and the second rolling member 54 can abut against the other inner wall surface of the groove 411. Here, the groove 411 can have two side walls, and the first rolling member 52 and the second rolling member 54 respectively abut against the two side walls. The groove 411 can also have a bottom wall and two side walls, and the first rolling member 52 and the second rolling member 54 can abut against any two walls.

[0064] It is understandable that by inserting a portion of the support member 50 into the groove 411, the wheel body 40 can also limit the support member 50 to a certain extent, preventing the wheel body 40 from sliding out from the outside of the wheel body 40, thereby ensuring that the support member 50 can limit the wheel body 40.

[0065] In some specific examples, the two sidewalls of the groove 411 that mate with the rolling element extend obliquely relative to the plane on which the wheel body 40 is located. One sidewall is located above the plane, and the other sidewall is located below the plane. The angles between the two sidewalls and the plane are the same. This makes the tilt angles of the first rolling element 52 and the second rolling element 54 symmetrical and the same. This facilitates the manufacturing and forming of the support 50, improves the versatility of the support 50, and facilitates the installation of the support 50 in the wheel bracket 30 without having to consider the front and back. This reduces the number of parts, improves assembly efficiency, and facilitates maintenance and replacement.

[0066] In some examples, the groove 411 includes a first inner wall surface, a second inner wall surface, and a third inner wall surface. The first inner wall surface and the third inner wall surface are respectively arranged on both sides of the second inner wall surface. The included angle between the first inner wall surface and the second inner wall surface is β1, and the included angle between the third inner wall surface and the second inner wall surface is β2. β1 and β2 are the same. This allows the first rolling element 52 and the second rolling element 54 to exert symmetrical forces on the wheel body 40 after the support member 50 is assembled in place. This can counteract the axial external force on the wheel body 40 and prevent the wheel body 40 from coming out of the wheel bracket.

[0067] In some specific examples, the first inner wall surface and the second inner wall surface extend inclinedly away from each other, that is, the first inner wall surface and the second inner wall surface form an inclined surface. This facilitates the manufacturing and forming of the wheel bracket 30, facilitates the installation of the support member 50 in the wheel bracket 30, and enables the support member 50 to support and limit the wheel body 40 in multiple directions, thereby improving the stability of the wheel body 40 during rotation.

[0068] like Figure 6 and Figure 7 As shown, in some examples, the wheel assembly 300 further includes: a support bracket 60 and an elastic member 70. The support bracket 60 is disposed within the wheel bracket 30 and can be fixedly connected to the wheel bracket 30. The support member 50 is disposed inside the support bracket 60, that is, the support member 50 is disposed between the support bracket 60 and the wheel body 40. The elastic member 70 is disposed between the support member 50 and the support bracket 60, and the elastic member 70 can respectively abut against the support member 50 and the support bracket 60. The support member 50 is installed on the outside of the rotating body 40 by the support bracket 60 and the elastic member 70. Under the action of the elastic member 70, the support member 50 forms a movable limiting structure. This facilitates the installation of the support member 50 and the rotating body 40 on the rotating bracket 30. At the same time, the support member 50 can support the rotating body 40 during long-term operation. In addition, it can adjust the position of the rotation center of the rotating body 40 in time when the rotating body 40 has a certain eccentric movement, thereby improving the reliability of the rotation of the rotating body 40.

[0069] like Figure 7 As shown, in some examples, the support bracket 60 has two limiting plates 61, which are spaced apart along the axial direction of the wheel body 40. The support member 50 is sandwiched between the two limiting plates 61. The support member 50 has a guide groove 56, and the limiting plates 61 have guide ribs 62, or the support member 50 has guide ribs 62, and the limiting plates 61 have guide grooves 56. The guide ribs 62 and guide grooves 56 are slidably engaged. The guide ribs 62 extend radially along the wheel body 40. That is, the support member 50 and the support bracket 60 can be detachably engaged. When the support member 50 is installed on the support bracket 60, the two can be slidably engaged through the guide ribs 62 and guide grooves 56. The sliding direction is radial to the wheel body 40. At the same time, an elastic member 70 is provided between the support member 50 and the support bracket 60. The elastic member 70 can apply a force to the support member 50 in the direction of movement towards the wheel body 40, ensuring that the support member 50 fits against the wheel body 40 and achieving reliable positioning.

[0070] like Figure 5As shown, in some examples, the wheel bracket 30 has a clearance notch 32, which is connected to the installation space 31. The support bracket 60 can be set at the clearance notch 32. By setting the clearance notch 32, the installation of the support bracket 60 and the support 50 can be facilitated, and the support 50 can be prevented from protruding too much inward, which would affect the assembly and operation of the wheel body 40.

[0071] It should be noted that a support bracket 60 may be provided on the outside of each support member 50, or a support bracket 60 may be provided on the outside of some support members 50.

[0072] According to some embodiments of the present invention, the wheel assembly 300 further includes a drive assembly 80, which is used to drive the wheel body 40 to rotate. The drive assembly 80 can directly drive the wheel body 40 to rotate, so as to simplify the structure and improve the compactness of the structure. The drive assembly 80 can also indirectly drive the rotation of the wheel body 40, so as to adjust the rotation speed of the wheel body 40, etc.

[0073] like Figure 4 and Figure 8 As shown, in some examples, the drive assembly 80 includes a drive motor 81 and a gear 82. The outer side of the wheel body 40 has a gear ring 412. The drive motor 81 drives the gear 82 to rotate, and the gear ring 412 meshes with the gear 82, thereby driving the wheel body 40 to rotate. Of course, the gear 82 and gear ring 412 can also be replaced by a belt, which drives the wheel body 40 to rotate. The drive assembly 80 is located on one side of the wheel body 40 in the radial direction.

[0074] In addition, the drive assembly 80 can also be located on one side of the axial direction of the wheel body 40. The output shaft of the drive assembly 80 is located on the rotation axis of the wheel body 40, and the output shaft can be fixed to the center of the wheel body 40 by a bushing.

[0075] like Figure 1 As shown, in some examples, a support member 50 is connected to the wheel bracket 30 via a support member bracket 60. The support member bracket 60 and the drive assembly 80 are respectively arranged at the two ends of the radial direction of the wheel body 40, that is, the support member bracket 60 is arranged on the opposite side of the drive assembly 80. This allows the support member 50 on the opposite side of the drive assembly 80 to be movable. When the drive assembly 80 drives the wheel body 40 to rotate, even if the side of the drive assembly 80 acts on the wheel body 10, forming a certain thrust that pushes the wheel body 10 eccentrically, the support member 50 can also apply a reverse force under the action of the elastic member 70 to balance the external forces on the wheel body 10 and prevent the wheel body 10 from being eccentric.

[0076] According to some embodiments of the present invention, the wheel body 40 includes a wheel frame 41 and an adsorption member 42. The adsorption member 42 is disposed inside the wheel frame 41. The outer side of the wheel frame 41 has a toothed ring 412 and an inwardly recessed groove 411. The toothed ring 412 and the groove 411 are arranged at intervals along the axial direction of the wheel body 40, thereby ensuring that the arrangement of the support member 50 does not interfere with the cooperation between the drive assembly and the wheel body 40, thus guaranteeing the reliable operation of the wheel body 40.

[0077] like Figure 10 As shown, in some examples, the rotating frame 41 includes a base frame 413 and a top cover 414. The adsorption element 42 is installed inside the base frame 413, and the top cover 414 can be snapped into the base frame 413 to fix the adsorption element 42. The base frame 413 has a groove 411 and a toothed ring 412, and the overall structure is simple and has good stability.

[0078] The adsorption element 42 can adsorb and release moisture. The material of the adsorption element 42 can be silica gel, molecular sieve, etc. The adsorption element 42 can adsorb moisture in the air at low temperature to dry the air, and the adsorption element 42 can release moisture at high temperature to humidify the air, thus eliminating the need for additional water tank humidification or built-in compressor, saving production costs.

[0079] The air handling equipment 1000 according to an embodiment of the present invention includes a rotor assembly 300 according to an embodiment of the present invention. By using the rotor assembly 300, air leakage due to poor sealing of the air handling equipment can be avoided, ensuring the net fresh air rate or total heat exchange effect of the air handling equipment and improving user comfort.

[0080] According to some embodiments of the present invention, an air handling device 1000 includes a first air inlet 1003, a first air outlet 1004, a second air inlet 1005, and a second air outlet 1006. An air supply duct 1001 is formed between the first air inlet 1003 and the indoor air outlet 1004. The first air inlet 1003 can draw in outdoor air and purify it before introducing it into the room. An exhaust duct 1002 is formed between the second air inlet 1005 and the second air outlet 1006. The second air inlet 1005 can draw in indoor air and exhaust it to the outside.

[0081] like Figure 4As shown, in some specific examples, the rotor assembly 300 is arranged at an angle relative to the entire device. The rotor assembly 300 has a first air duct component 100 on its lower side and a second air duct component 200 on its upper side. The angle of the rotor assembly 300 is the same as the angle of the two air duct components near its side surface. The air supply direction of the air supply duct 1001 and the air exhaust direction of the air exhaust duct 1002 are approximately the same as the extension direction of the entire device. Thus, the air supply direction and the exhaust direction can be simultaneously tilted towards the rotor assembly 300, which is beneficial for the air in the duct to fully contact the rotor assembly 300, thereby maximizing the performance of the rotor assembly 300. Moreover, by tilting the rotor assembly 100, the thickness space occupied can be reduced, that is, the vertical dimension of the air handling unit 1000 can be reduced, improving the aesthetics of the appearance, and at the same time facilitating the installation and use of the air handling unit 1000 in different occasions.

[0082] like Figure 11 As shown, in some examples, a heating element 4 is installed in the air supply duct 1001. The air heated by the heating element 4 is passed to the rotating wheel assembly 300, which can release the moisture adsorbed by the adsorbent 42, and then send the high humidity air into the room through the air supply duct 1001 to improve the comfort of the room.

[0083] It should be noted that the rotary wheel assembly 300 can rotate between the air supply duct 1001 and the air exhaust duct 1002, thereby driving the adsorption member 42 to rotate. Part of the adsorption member 42 is located in the air supply duct 1001, and the other part of the adsorption member 42 is located in the air exhaust duct 1002. By rotating the rotary wheel assembly 300, part of the adsorption member 42 rotates from the air supply duct 1001 to the air exhaust duct 1002, while the other part of the adsorption member 42 rotates from the air exhaust duct 1002 to the air supply duct 1001, and this cycle repeats continuously.

[0084] like Figure 11 As shown, in some examples, the air handling unit 1000 further includes a purification component 3, a heating element 4, and a filter element 5. The purification component 3 is disposed between the first air inlet 1003 and the rotor assembly 100. The heating element 4 is disposed between the first air inlet 1003 and the rotor assembly 100, and is located behind the purification component 3. The filter element 5 is disposed between the second air inlet 1005 and the rotor assembly 300. Both the purification component 3 and the filter element 5 can remove fine particulate matter and other impurities from the air. The position of the heating element 4 corresponds to the position of the air supply duct 1001, and the heating element 4 can heat the outdoor air passing through the heating element 4.

[0085] like Figure 11As shown, in some examples, the air handling unit 1000 has multiple sensors 2, which can be temperature sensors or humidity sensors. By working together, the temperature and humidity sensors can monitor changes in indoor and outdoor temperatures and humidity. The sensors 2 can be installed at the first air inlet 1003, the first air outlet 1004, or the second air inlet 1005, so that the sensors 2 can accurately and quickly monitor indoor and outdoor conditions, allowing the air handling unit 1000 to switch operating modes in a timely manner and improve the user experience.

[0086] In some examples, the air handling unit 1000 includes a first operating mode and a second operating mode. In the first operating mode, air is introduced into the room through the air supply duct 1001, and the adsorption element 42 of the rotor assembly 300 absorbs moisture and heat from the air, thereby introducing the dried and cooled air into the room.

[0087] In the second working mode, the heating element 4 is working. The air heated by the heating element 4 is introduced into the room through the exhaust duct 1002. The adsorption element 42 releases moisture when heated, thereby introducing the humidified and heated air into the room.

[0088] In some specific examples, the first working mode is the total heat recovery mode. In the hot and humid summer, the outdoor air temperature is high and relatively humid. The rotor assembly 300 runs at high speed. The outdoor air enters the air supply duct 1001 through the first air inlet 1003. After being purified by the purification assembly 3, it reaches the rotor assembly 300. The adsorption element 42 of the rotor assembly 300 adsorbs the moisture and heat in the outdoor air, so that the low-temperature dry air enters the room through the first air outlet 1004.

[0089] Meanwhile, indoor air enters the exhaust duct 1002 through the second air inlet 1005. The air is filtered by the filter element 5. When the air passes through the rotating assembly 300, since the indoor temperature and humidity are lower than the outdoor temperature, the adsorption element 42, which has adsorbed outdoor moisture and heat, spontaneously releases moisture and heat in the exhaust duct 1002. The air is then discharged to the outside through the second air outlet 1006. Through repeated circulation, the effect of cooling and dehumidification is achieved indoors.

[0090] In some specific examples, the second working mode is the humidification mode. In the cold and dry winter, the indoor air temperature is high and relatively dry. The rotor assembly 300 runs at low speed and the heating element 4 starts to work. Outdoor air enters the air supply duct 1001 through the first air inlet 1003 and is purified by the purification assembly 3. Since the heating element 4 is turned on, the outdoor air is heated by the heating element 4 and then passes through the rotor assembly 300. The high temperature of the outdoor air can evaporate the moisture in the rotor assembly 300, so that the high humidity gas enters the room through the first air outlet 1004.

[0091] Simultaneously, indoor air enters the exhaust duct 1002 through the second air inlet 1005. The air is filtered by the filter element 5. When the air passes through the rotating assembly 300, the adsorption element 42 absorbs moisture and heat from the indoor air, allowing the low-temperature, dry air to be discharged outdoors through the second air outlet 1006. As the rotating assembly 300 continuously rotates in the exhaust duct 1002, the adsorption element 42 absorbs moisture and heat from the indoor air in the exhaust duct 1002, and continuously evaporates moisture in the supply duct 1001, returning the purified and humidified air to the room. Through this reciprocating cycle, the indoor air is purified and humidified.
