Detailed Implementation

[0037] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0038] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0039] like Figures 1 to 3 As shown, the air handling rotor frame of this application includes a frame body 1 and a plurality of ventilation valves 2. The ventilation valves 2 are fixed to the frame body 1 to control the ventilation of the frame body 1. The frame body 1 includes a rotor receiving cavity 11 and a plurality of ventilation holes 12. Along the circumference of the rotor receiving cavity 11, the plurality of ventilation holes 12 are spaced apart on the periphery of the rotor receiving cavity 11. The ventilation valves 2 are correspondingly disposed in the ventilation holes 12, and the ventilation valves 2 include a valve frame 21 and a valve plate 22. The valve plate 22 is rotatably connected to the valve frame 21 to open and close the ventilation holes 12. Specifically, the valve frame 21 is fixed to the edge of the ventilation hole 12, and the opening and closing of the ventilation hole 12 is controlled by the rotation of the valve plate 22.

[0040] This design allows the air handling rotor frame to ventilate through its own ventilation holes 12, improving the ease of use. Furthermore, when the air handling rotor frame is used in ventilation ducts, there is no need for additional bypass ducts, reducing the size and cost of the air handling unit.

[0041] In some embodiments, the frame body 1 is rectangular, the rotating wheel accommodating cavity 11 is circular, the rotating wheel accommodating cavity 11 is located in the middle region of the frame body 1, and the plurality of ventilation holes 12 are respectively located at the four corners of the frame body 1. The number of the ventilation holes 12 is preferably but not limited to four. The ventilation valve 2 is provided in one-to-one correspondence with the ventilation holes 12, the valve frame 21 and the valve plate 22 are triangular, and the valve plate 22 is attached to the valve frame 21 when the ventilation valve 2 is in the closed state. In this way, the ventilation valve 2 can be more conveniently arranged at the four corners of the frame body 1, and the space at the four corners of the frame body 1 can be utilized to a greater extent.

[0042] Further in combination with Figure 4 and Figure 5 As shown in the drawings, the valve frame 21 comprises a limiting plate 211 located at the periphery of the valve frame 21. When the ventilation valve 2 is in the open state, the valve plate 22 contacts the limiting plate 211. In this way, the rotation angle of the valve plate 22 is controlled, and the ventilation effect of the air treatment rotating wheel frame is improved. The limiting plate 211 is connected to the valve frame 21 perpendicularly along the thickness direction of the valve frame 21, and the limiting plate 211 and the valve plate 22 are located on the same side frame of the valve frame 21. In order to make the limiting plate 211 more stably bear the valve plate 22, the limiting plate 211 can be provided in plurality and arranged at intervals on the side frame of the valve frame 21.

[0043] Further in combination with Figure 6 and Figure 7 As shown in the drawings, in other embodiments, the valve plate 22 comprises a plate body 221 and a connecting arm 222. The limiting plate 211 is located on the side of the valve frame 21 away from the plate body 221, that is, the limiting plate 211 and the plate body 221 are located on opposite sides of the valve frame 21. The connecting arm 222 is fixed to the plate body 221 and penetrates through the valve frame 21. When the ventilation valve 2 is in the open state, the connecting arm 222 contacts the limiting plate 211 to limit the rotation angle of the limiting plate 211. In order to make the connecting arm 222 more conveniently rotate with the plate body 221 and contact the limiting plate 211, the connecting arm 222 is arranged in an arc shape.

[0044] As shown in the drawings, Figure 8 and Figure 9 In other embodiments, the connecting arm 222 is arranged in a straight plate shape and is connected to the plate body 221 perpendicularly. When the ventilation valve 2 is in the closed state, the connecting arm 222 penetrates through the valve frame 21 along the thickness direction of the valve frame 21.

[0045] As shown in the drawings, Figures 10 to 12As shown, in some embodiments, each ventilation valve 2 is provided with only one valve frame 21 and one valve plate 22. In other embodiments, each ventilation valve 2 is provided with only one valve frame 21 and two valve plates 22, i.e. each valve frame 21 is provided with two valve plates 22. Specifically, the valve frame 21 comprises an outer frame 212 and a middle reinforcing rod 213 connected to the outer frame 212. The valve plate 22 comprises a first valve plate 223 and a second valve plate 224. The first valve plate 223 and the second valve plate 224 are both rotatably connected to the outer frame 212 and are respectively located at opposite sides of the middle reinforcing rod 213. Of course, the first valve plate 223 and the second valve plate 224 can also be rotatably connected to the middle reinforcing rod 213.

[0046] In some other embodiments, each ventilation valve 2 is provided with one valve frame 21 and one valve plate 22, and each ventilation valve 2 is also provided with one valve frame 21 and two valve plates 22.

[0047] In some embodiments, in order to make the contact between the valve plate 22 and the valve frame 21 more airtight, the ventilation valve 2 comprises a sealing member 24. The sealing member 24 is arranged on the peripheral side of the valve frame 21 or the valve plate 22. Specifically, the sealing member 24 is arranged on the inner side edge of the valve frame 21, and the valve plate 22 can contact the sealing member 24 when closed. Alternatively, the sealing member 24 is arranged on the outer side edge of the valve plate 22, and the valve plate 22 can drive the sealing member 24 to rotate to contact the valve frame 21 when closed. When the ventilation valve 2 is in the closed state, the sealing member 24 is located between the valve frame 21 and the valve plate 22. The sealing member 24 can be a sealing ring, sealing cement or other sealing components.

[0048] Further combining Figure 13 As shown, in some embodiments, in order to make the valve plate 22 rotate more smoothly, the ventilation valve 2 further comprises a hinge assembly 23 connected to the valve frame 21 and the valve plate 22. The hinge assembly 23 comprises a hinge body 231 and an elastic member 232. One side of the hinge body 231 is connected to the valve frame 21, and the other side is connected to the valve plate 22. The elastic member 232 is arranged on the hinge body 231 and applies an elastic force to the hinge body 231, so that the valve plate 22 always has a tendency to open or close, thereby making the ventilation valve 2 automatically open or close.

[0049] Specifically, when the ventilation valve 2 is in the open state, the elastic member 232 is compressed, and the elastic member 232 applies an elastic force to the hinge body 231, so that the valve plate 22 has a tendency to close. In other embodiments, when the ventilation valve 2 is in the closed state, the elastic member 232 is compressed, and the elastic member 232 applies an elastic force to the hinge body 231, so that the valve plate 22 has a tendency to open. The elastic member 232 is a spring, a leaf spring or other elastic structure.

[0050] Further combiningFigures 14 to 17 As shown, in order to further improve the automation degree of the ventilation valve 2, the air handling runner frame comprises a cable assembly 3. One end of the cable assembly 3 is connected to the valve plate 22, and the cable assembly 3 is used to overcome the elastic force of the elastic member 232 to drive the valve plate 22 to rotate relative to the valve frame 21. Specifically, the cable assembly 3 comprises a cable 31 and a driving member 32. One end of the cable 31 is connected to the driving member 32, and the other end is connected to the valve plate 22. The cable 31 can be directly connected to the valve plate 22, and if the valve plate 22 is provided with a connecting arm 222, the cable 31 is connected to the connecting arm 222. The driving member 32 is used to take up and release the cable 31. The pulling force of the cable 31 is greater than the elastic force of the elastic member 232.

[0051] Specifically, the elastic member 232 applies an elastic force to the hinge body 231, so that when the valve plate 22 has a tendency to close, the cable 31 is used to pull the valve plate 22 to rotate to overcome the elastic force of the elastic member 232, so that the ventilation valve 2 is converted from the closed state to the open state. In this process, if the driving member 32 does not release the cable 31, the ventilation valve 2 is always in the open state.

[0052] In other embodiments, the elastic member 232 applies an elastic force to the hinge body 231, so that when the valve plate 22 has a tendency to open, the cable 31 is used to pull the valve plate 22 to rotate to overcome the elastic force of the elastic member 232, so that the ventilation valve 2 is converted from the open state to the closed state. In this process, if the driving member 32 does not release the cable 31, the ventilation valve 2 is always in the closed state.

[0053] As shown, Figure 18 The present application also provides an air handling unit, comprising an air duct 4, a runner 5 and an air handling runner frame as described above. The runner 5 is installed in the runner accommodating cavity 11, and the air handling runner frame is fixed in the air duct 4. The runner 5 comprises a heat recovery runner or a dehumidification runner. When the air handling runner frame is applied to the air duct 4, only the ventilation valve 2 at the four corners of the frame body 1 needs to be opened to ventilate, without the need for additional bypass air ducts, and thus without the need to increase the volume of the air duct 4, thereby reducing the cost and volume of the air handling unit.

[0054] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
