[0028] The principles and features of the present application will be described below with reference to the attached drawings. The examples given are only for explaining the present application and are not intended to limit the scope of the present application.

[0029] The embodiment of the present application provides a return air panel structure, which is applied to the fresh air module 100.

[0030] As Figures 2 to 5 shown, the return air panel structure includes: a return air panel 1, an air valve 2 and a driving motor 3. The return air panel 1 is provided with a return air inlet 11, and a return air grille 12 is provided at the return air inlet 11, and the return air grille 12 and the return air panel 1 are of an integral structure. The return air inlet 11 allows indoor air to enter the fresh air module 100.

[0031] The air valve 2 is movably connected to the return air panel 1 and is configured to open or close the return air inlet 11.

[0032] The driving motor 3 is installed on the return air panel 1 and is configured to drive the air valve 2 to move relative to the return air panel 1. The driving motor 3 can be, but is not limited to, a stepping motor.

[0033] For the return air panel structure provided by the embodiment of the present application, the return air grille 12 and the return air panel 1 are set to be of an integral structure, which can be integrally formed (such as integrally injection molded), and the assembly process between the return air grille 12 and the return air panel 1 can be omitted, thereby facilitating the improvement of the assembly efficiency.

[0034] In some exemplary embodiments, the return air panel 1 and the return air grille 12 are integrally formed plastic parts.

[0035] Compared with the solution where the return air grille 12 and the return air panel 1 are respectively made of sheet metal parts and plastic parts and assembled separately, in this solution, the return air grille 12 and the return air panel 1 can be integrally injection-molded, which is beneficial to reducing production costs and facilitating the integrally forming of the installation structures of the air valve 2 and the drive motor 3 on the return air panel 1 as needed, enabling the return air panel structure to form a module, and then it can be assembled with the housing of the fresh air module 100 in the form of a module, which is also beneficial to improving the assembly efficiency.

[0036] In some exemplary embodiments, the air valve 2 is rotatably connected to the return air panel 1. In this way, the opening angle of the air valve 2 can be adjusted as needed, and the air valve 2 also functions as a deflector.

[0037] As Figures 2 to 5 shown, the return air panel 1 is provided with a first connection protrusion 13 and a second connection protrusion 14. The drive motor 3 is installed on the first connection protrusion 13, one end of the air valve 2 is rotatably connected to the first connection protrusion 13, and the other end of the air valve 2 is rotatably connected to the second connection protrusion 14.

[0038] The structural forms of the first connection protrusion 13 and the second connection protrusion 14 are not limited and can be reasonably set as needed. For example: the first connection protrusion 13 can be an open box-shaped structure with a relatively large size to accommodate at least a part of the drive motor 3; the second connection protrusion 14 can be a plate-shaped structure with a relatively small size to support the other end of the air valve 2. The first connection protrusion 13 can be generally rectangular, and the second connection protrusion 14 can be generally right-angled trapezoidal.

[0039] The connection forms between the air valve 2 and the first connection protrusion 13 and the second connection protrusion 14 are not limited. For example, the air valve 2 is provided with a rotating shaft, and the first connection protrusion 13 and the second connection protrusion 14 are provided with shaft holes 141, and the rotating shaft of the air valve 2 is rotatably inserted into the shaft holes 141. The motor shaft of the drive motor 3 can also be inserted into the shaft hole 141 of the first connection protrusion 13 and connected to the rotating shaft of the air valve 2 to drive the air valve 2 to rotate.

[0040] The first connection protrusion 13 and the second connection protrusion 14 and the return air panel 1 are of an integral structure and can be integrally injection-molded.

[0041] In some exemplary embodiments, as Figure 2 、 Figure 5 shown, the return air panel structure further includes a motor gland 4. The motor gland 4 is connected to the first connection protrusion 13 and encloses a motor cavity for accommodating the drive motor 3 with the first connection protrusion 13.

[0042] In this way, the drive motor 3 can be hidden in the motor cavity formed by enclosing the motor gland 4 and the first connecting protrusion 13, which is beneficial to avoiding the influence of the drive motor 3 by other external structures, thereby being beneficial to improving the reliability of use of the drive motor 3.

[0043] In some exemplary embodiments, one of the first connecting protrusion 13 and the motor gland 4 is provided with a buckle 131, and the other is provided with a card hole 42, and the buckle 131 is engaged with the card hole 42, as Figure 5 shown.

[0044] In this way, compared with the screw fixing method, the motor gland 4 can be snap-fitted on the first connecting protrusion 13, which is convenient for the assembly and fixing between the motor gland 4 and the first connecting protrusion 13, and is also convenient for quickly disassembling the motor gland 4 from the first connecting protrusion 13, facilitating the installation and disassembly of the drive motor 3.

[0045] Of course, the connection method between the motor gland 4 and the first connecting protrusion 13 is not limited to the snap-fitting method, and can also be a fastener connection or other connection methods.

[0046] In some exemplary embodiments, as Figure 2 、 Figure 3 and Figure 5 shown, the number of the buckles 131 is multiple, and the multiple buckles 131 are arranged along the circumferential direction of the motor gland 4. The number of the card holes 42 is equal to the number of the buckles 131 and corresponds to each other one by one. This is beneficial to improving the fixing reliability of the motor gland 4.

[0047] In some exemplary embodiments, as Figure 2 shown, the motor gland 4 is provided with a lug 41, and the card hole 42 is arranged on the lug 41. The buckle 131 is provided with a guiding inclined surface 1311, as Figure 3 shown, and the guiding inclined surface 1311 is arranged to guide the buckle 131 to be snapped into the card hole 42.

[0048] In some exemplary embodiments, as Figure 2 and Figure 3 shown, the first connecting protrusion 13 is provided with a first notch 132, and the motor gland 4 is provided with a second notch 43. The first notch 132 and the second notch 43 enclose a wiring opening 46, as Figure 5 shown, and the wiring opening 46 is for the wire body of the drive motor 3 to pass through, facilitating the wiring of the drive motor 3. The shapes of the first notch 132 and the second notch 43 can be, but are not limited to, semi-circular, and then the wiring opening 46 can be, but is not limited to, circular.

[0049] In some exemplary embodiments, the motor gland 4 is provided with a wiring buckle 45, as Figure 5As shown, it facilitates the wiring of the wire body of the driving motor 3 after it extends outside the motor cavity. The wiring buckle 45 can be located in the vicinity of the wiring opening 46.

[0050] In some exemplary embodiments, a stop portion is provided at one end of the first connecting protrusion 13 facing the motor gland 4, and a stop mating portion is provided at one end of the motor gland 4 facing the first connecting protrusion 13. One of the stop portion and the stop mating portion includes a stop step groove (not shown in the figure), and the other includes a stop step protrusion 134 (as Figure 3 shown), and the stop step protrusion 134 is inserted into the stop step groove and is in stop mating with the stop step groove.

[0051] In this way, when the motor gland 4 covers the first connecting protrusion 13, when the stop step protrusion 134 abuts against the stop step groove, it indicates that the installation is in place, and it can limit the motor gland 4 from further pressing against the first connecting protrusion 13. The cooperation between the stop step protrusion 134 and the stop step groove plays a role of limiting and positioning, and also plays a role of labyrinth seal, which is beneficial to preventing external water vapor from entering the motor cavity.

[0052] In some exemplary embodiments, the first connecting protrusion 13 is provided with a connecting column 133, as Figure 3 shown, and the driving motor 3 is fixedly connected to the connecting column 133 through a fastener.

[0053] The fastener can be but is not limited to structures such as screws and bolts. The fastener has high connection strength and is firmly fixed. The number of the connecting columns 133 can be but is not limited to multiple, and the multiple connecting columns 133 are arranged at intervals along the circumference of the driving motor 3.

[0054] In some exemplary embodiments, a sealing rib 15 protrudes from the side peripheral wall of the return air grille 12, as Figure 4 and Figure 5 shown, and the return air panel structure further includes a sealing layer 21, as Figure 4 and Figure 5 shown. The sealing layer 21 is attached to the plate surface of the air valve 2 facing the return air opening 11 and is arranged to abut and seal with the sealing rib 15. This is beneficial to improving the sealing performance when the return air opening 11 is closed and is beneficial to preventing condensation and abnormal noises such as whistling. The sealing layer 21 can be but is not limited to sealing sponge.

[0055] In some exemplary embodiments, a snap button 17 is provided at one end of the return air panel 1, as Figure 3 shown, and the snap button 17 is arranged to be inserted into the housing 5 of the fresh air module 100. This is beneficial to reducing the fasteners for fixing the return air panel 1 and the housing 5 and is beneficial to improving the assembly efficiency.

[0056] In some exemplary embodiments, the number of the snap buttons 17 is multiple, as Figure 3As shown, a plurality of snap fasteners 17 are arranged at intervals along the length direction of the return air panel 1. The snap fasteners 17 can be inserted and mated with the jacks of the housing 5 and can rotate relative to the housing 5 so that the return air panel 1 can rotate relative to the housing 5 within a certain range.

[0057] In some exemplary embodiments, grid-shaped ribs 18 are provided on the outer plate surface of the return air panel 1, as Figure 1 shown. These ribs 18 can serve as a decorative function and a reinforcing rib function.

[0058] As Figure 1 shown, the embodiment of the present application also provides a fresh air module 100, including: a housing 5 and a return air panel structure according to any one of the above embodiments. A duct is provided inside the housing 5. The return air panel structure is connected to the housing 5, and the return air opening 11 is communicated with the duct.

[0061] A volute can be provided inside the housing 5, and a part of the duct is located inside the volute. A wind wheel is provided inside the volute, and the wind wheel is used to drive the air flow.

[0062] In some exemplary embodiments, the duct includes a fresh air duct and an exhaust duct. The return air opening 11 is communicated with the inlet of the exhaust duct, and the exhaust duct is arranged to discharge the indoor polluted air to the outside. The inlet of the fresh air duct is communicated with the fresh air pipe and is arranged to input the outdoor fresh air into the room.

[0063] In the exhaust mode, the exhaust duct is conducted, and the air valve 2 can swing under the drive of the drive motor 3. By changing the swing angle, the air direction control of the return air opening 11 is realized. The indoor air enters the exhaust duct through the return air opening 11. Under the action of the air pressure difference, the indoor air will be discharged along with the exhaust pipe and reach the outside from the room. With the continuous rotation of the wind wheel inside the housing, the continuous discharge of the indoor air will also be realized, so as to achieve the purpose of cleaning and replacing the indoor polluted air.
