[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0034] like Figures 1 to 8 As shown, an embodiment of the present application provides a ventilation module 100 , comprising: a ventilation housing 1 , a ventilation fan 2 and a motor base 3 .

[0035] Among them, Figure 7 and Figure 8 As shown, the inner wall of the ventilation housing 1 is provided with a mounting bracket 12. The ventilation fan 2 is provided in the ventilation housing 1. Figure 2 and Figure 3 As shown, the ventilation fan 2 includes a wind wheel 21 and a wind wheel motor 22 connected to the wind wheel 21. The motor base 3 is located in the ventilation housing 1 and is configured to be fixed to the mounting bracket 12 from the inner side of the ventilation housing 1, as shown in FIG. Figure 3 The wind wheel motor 22 is fixed to the motor base 3.

[0036] The ventilation module 100 provided in the embodiment of the present application adds a mounting bracket 12 on the inner wall surface of the ventilation shell 1, so that the motor base 3 can be directly fixed on the mounting bracket 12 from the inner side of the ventilation shell 1 without turning the ventilation shell 1 over and screwing from the outside, thereby improving the assembly convenience of the motor base 3 and helping to improve the assembly efficiency of the ventilation module 100.

[0037] In some exemplary embodiments, the ventilation housing 1 includes a chassis 11 , and the mounting bracket 12 and the chassis 11 are configured as an integrated structure.

[0038] This helps improve the connection strength and fixation reliability between the mounting bracket 12 and the chassis 11. The mounting bracket 12 can be a sheet metal component, and the chassis 11 can also be a sheet metal component. The mounting bracket 12 can be welded to form an integrated structure with the chassis 11. Alternatively, the mounting bracket 12 and the chassis 11 can be formed into an integrated structure by casting, injection molding, etc.

[0039] In some exemplary embodiments, Figure 4 and Figure 6 As shown, the motor base 3 is provided with first limiting grooves 31 at intervals along its axial direction. The main body 223 of the wind turbine motor is provided with sealing members 221 at both ends of the axial direction. Figure 4 As shown. A portion of the sealing member 221 is embedded in the first limiting groove 31 and has an interference fit with the first limiting groove 31. The sealing member 221 can be, but is not limited to, a sealing ring (such as a rubber ring). The first limiting groove 31 can be an arc-shaped groove.

[0040] This can achieve a tight fit between the wind wheel motor 22 and the motor base 3, thereby achieving effective fixation of the wind wheel motor 22 and the motor base 3, and is beneficial to avoiding the wind wheel motor 22 from colliding with the motor base 3 during long-term operation, causing abnormal noise.

[0041] In some exemplary embodiments, the groove wall of the first limiting groove 31 and one of the sealing members 221 are provided with an inserting tongue 2211 (eg, Figure 4 As shown), the other has a slot 311 (as shown Figure 6 The tongue 2211 is configured to be inserted into the slot 311.

[0042] The cooperation between the tongue 2211 and the slot 311 can play a role in positioning and preventing mistakes in the assembly of the wind wheel motor 22, which is helpful to avoid the wind wheel motor 22 from being installed incorrectly or upside down, so that the information identification code reflecting the wind wheel motor 22 can be correctly displayed without being blocked.

[0043] The insert tongue 2211 can be disposed on a lateral wall of the seal 221, or alternatively, on an axial end wall of the seal 221. The insert tongue 2211 is configured to be inserted into the slot 311 along the radial direction of the wind turbine motor 22. The specific form of the insert tongue 2211 is not limited and may be in the form of a plate, block, column, or other shapes. The shape of the slot 311 is adapted to match the shape of the insert tongue 2211.

[0044] Alternatively, only one first limiting groove 31 and the sealing member 221 may be matched with each other via the tongue 2211 and the slot 311 . Alternatively, both first limiting grooves 31 and both sealing members 221 may be matched with each other via the tongue 2211 and the slot 311 .

[0045] In some exemplary embodiments, Figure 3 As shown, the ventilation module 100 further includes a motor cover 4 , which is disposed on the motor base 3 and together with the motor base 3 forms an installation cavity 37 , in which the main body 223 of the wind wheel motor is located.

[0046] This can provide all-round protection for the wind rotor motor 22 , which is beneficial to improving the reliability of the wind rotor motor 22 .

[0047] The motor cover 4 and the motor base 3 can be detachably connected by fasteners (such as screws), snap connections, or other connection methods. During assembly, the motor base 3 can be first fixed to the mounting bracket 12, and then the wind rotor motor 22 can be installed on the motor base 3. Finally, the motor cover 4 is covered and fixed to achieve reliable fixation of the wind rotor motor 22.

[0048] In some exemplary embodiments, the motor cover 4 is provided with second limiting grooves 41 corresponding to the first limiting grooves 31 at intervals along its axial direction. Figure 4 As shown, a portion of the sealing member 221 is embedded in the second limiting groove 41 and has an interference fit with the second limiting groove 41. The second limiting groove 41 can be an arc-shaped groove, and the second limiting groove 41 can enclose a circular groove with the corresponding first limiting groove 31.

[0049] In this way, the wind wheel motor 22 can be tightly fitted with the motor cover 4, thereby effectively fixing the wind wheel motor 22 and the motor cover 4, and helping to avoid the wind wheel motor 22 colliding with the motor cover 4 during long-term operation, causing abnormal noise.

[0050] In some exemplary embodiments, there is a gap between the main body 223 of the wind wheel motor and the wall of the installation cavity 37 , and the width of the gap is greater than 3 mm.

[0051] This is beneficial to avoid the gap width being too small, which may cause the wind rotor motor 22 to collide with the motor base 3 or the motor cover 4 during long-term operation and cause abnormal noise, and it is also beneficial to avoid the gap width being too small, which may cause the wind rotor motor 22 or the motor cover 4 to be difficult to install, and it is also beneficial to avoid the gap width being too large, which may cause the motor base 3 and the motor cover 4 to be too large.

[0052] In some embodiments, the axial gap between the main body 223 of the wind wheel motor and the cavity wall of the installation cavity 37 is smaller than the radial gap, and the width of the axial gap is greater than 3 mm.

[0053] Of course, the width of the gap is not limited to being greater than 3 mm and can be adjusted as needed.

[0054] In some exemplary embodiments, the motor base 3 is provided with a wiring structure configured to guide and position the wires of the wind rotor motor 22. This can reduce the pulling of the wires of the wind rotor motor 22 and help prevent the wires of the wind rotor motor 22 from being damaged.

[0055] The specific form of the wiring structure is not limited, for example, the wiring structure may include a wiring buckle 38 (such as Figure 4 、 Figure 6 and Figure 7 As shown), at least one of the limiting ribs. Figure 6 and Figure 7 In the figure, the dotted line indicates the direction of the line.

[0056] In some exemplary embodiments, the motor base 3 is provided with a wire pressing structure, which is configured to press the wire body of the wind wheel motor 22 so that the wire body of the wind wheel motor 22 can form a return bend outside the motor base 3.

[0057] This can prevent water vapor from flowing back into the wind rotor motor 22 along the wire body of the wind rotor motor 22 and damaging the wind rotor motor 22. Especially in bathroom scenarios, the part of the wire body of the wind rotor motor 22 located outside the motor base 3 is easily exposed to high-humidity water vapor, which can easily cause water vapor to condense into water on the wire body and flow along the wire body. The setting of the wire pressing structure allows the wire body of the wind rotor motor 22 to form a water return bend on the outside of the motor base 3. The position of the water return bend is lower than the part of the wire body of the wind rotor motor 22 on the inside of the motor base 3. Therefore, even if water vapor condenses into water on the wire body and flows along the wire body, it will not flow into the inside of the motor base 3 against gravity, thereby improving the reliability of the wind rotor motor 22.

[0058] The wire pressing structure may include at least one of the wiring buckle 38 and the limiting rib. In other words, the wire pressing structure and the wiring structure may be combined into one, and the wire pressing function may be achieved by reasonably setting the position and shape of the wiring structure.

[0059] In some exemplary embodiments, Figure 5 As shown, one of the motor base 3 and the mounting bracket 12 is provided with a positioning protrusion 32 , and the other is provided with a positioning groove 121 , and the positioning protrusion 32 is inserted into the positioning groove 121 .

[0060] The cooperation between the positioning protrusion 32 and the positioning groove 121 can play a positioning role in the assembly between the motor base 3 and the mounting bracket 12, which is conducive to the rapid alignment of the motor base 3 and the mounting bracket 12 to facilitate the subsequent assembly of fasteners.

[0061] The specific form of the positioning protrusion 32 is not limited and may be in the shape of a plate, block, column, etc. The shape of the positioning groove 121 is adapted to the shape of the positioning protrusion 32. The number of positioning protrusions 32 may be one or more. Multiple positioning protrusions 32 may be arranged at intervals.

[0062] In some exemplary embodiments, Figure 5 As shown, the motor base 3 has a first connection hole 33, and the mounting bracket 12 has a second connection hole 122. Fasteners are configured to sequentially penetrate the first connection hole 33 and the second connection hole 122, securing the motor base 3 to the mounting bracket 12. This allows the motor base 3 to be secured to the mounting bracket 12 from the inside of the ventilation housing 1, eliminating the need to flip the ventilation housing 1 over, making securing more convenient. Furthermore, the fasteners provide high connection strength, ensuring a secure fixation.

[0063] The number of the first connection holes 33 can be multiple, and the multiple first connection holes 33 are divided into two groups along the axial direction of the motor base 3. Each group of first connection holes 33 can also include multiple first connection holes 33. In this way, the motor base 3 and the mounting bracket 12 can be reliably connected by two groups of fasteners.

[0064] like Figure 5 As shown, the motor base 3 may have a first flange 36, with the positioning protrusion 32 and the first connection hole 33 provided on the first flange 36. The mounting bracket 12 may have a second flange 123, which is welded to the chassis 11. The second connection hole 122 and the positioning slot 121 are provided in the main body of the mounting bracket 12.

[0065] In some exemplary embodiments, Figure 6 As shown, the motor base 3 is provided with a wire groove 34, which is configured to accommodate the wires of the wind rotor motor 22. In this way, when the ventilation module 100 is used alone, the wires of the wind rotor motor 22 can be stuffed into the wire groove 34 to prevent the wires from being discharged.

[0066] In some exemplary embodiments, Figure 6As shown, the motor base 3 is provided with heat dissipation holes 35 to facilitate heat dissipation of the wind wheel motor 22. The number of heat dissipation holes 35 can be multiple to improve heat dissipation efficiency. The shape of the heat dissipation holes 35 is not limited and can be circular, rectangular, grid-shaped, etc.

[0067] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an air conditioner, comprising: an air conditioner main body 200 and a ventilation module 100 as described in any one of the above embodiments, connected to the air conditioner main body 200.

[0068] The air conditioner provided in the embodiment of the present application includes the ventilation module 100 of any one of the above embodiments, and thus has all the above beneficial effects, which will not be described in detail here.

[0069] In the embodiment of the present application, the air conditioner may be an indoor unit of a split-type air conditioner, or a split-type air conditioner as a whole including the indoor unit, or an integrated air conditioner.

[0070] In some exemplary embodiments, Figure 2 As shown, the air conditioner body 200 includes a housing 202, an indoor heat exchanger 204, and an indoor fan 206. The housing 202 is provided with a return air duct 2022 and a heat exchange chamber 2024. The return air duct 2022 has a first air inlet 2026, a first air outlet 2028, and a second air outlet 2030. The first air outlet 2028 is in communication with the heat exchange chamber 2024. The indoor heat exchanger 204 is located within the heat exchange chamber 2024, and the indoor fan 206 is located within the return air duct 2022. The first air inlet 2026 can be the return air outlet of the air conditioner.

[0071] like Figure 1 and Figure 2 As shown, the ventilation module 100 is located outside the housing 202 and is connected to the housing 202. The ventilation housing 1 is provided with a ventilation chamber 13, which has a second air inlet 131 and an air outlet 132. The second air inlet 131 is connected to the second air outlet 2030. The air outlet 132 can be connected to the outdoor space through an exhaust duct.

[0072] like Figure 2 As shown, the indoor fan 206 is configured to generate an airflow from the first air inlet 2026 to the first air outlet 2028. The ventilation fan 2 is configured to generate an airflow from the first air inlet 2026 to the second air outlet 2030.

[0073] The air conditioner provided in the embodiment of the present application adds a ventilation module 100 on the outside of the air conditioner main body 200, so that the air conditioner has a ventilation function in addition to the temperature control function. This is convenient for improving the indoor air comfort through the ventilation function when the indoor air is relatively uncomfortable, thereby improving the user experience and improving the market competitiveness of the air conditioner.

[0074] For example, in a bathroom, the air conditioner 200 can be used to control temperature; when indoor humidity is high, the ventilation function can be used to expel high-humidity water vapor; and after using the bathroom, the ventilation function can be used to remove odors. In this way, the bathroom can be equipped with only an air conditioner, which can combine the heating function of a bathroom heater with the ventilation function of a ventilation fan, and the temperature control function can also be combined with a cooling function, which is more functional and more conducive to improving the user experience.

[0075] Alternatively, in a kitchen scenario, the temperature control function can be achieved through the air-conditioning main body 200 to improve the user's experience in the kitchen; the high-humidity water vapor can be discharged through the ventilation function when the humidity in the kitchen is relatively high; and the odor in the kitchen can be removed through the ventilation function after cooking.

[0076] In some exemplary embodiments, Figure 2 As shown, the first air outlet 2028 and the second air outlet 2030 are spaced apart from each other. The ventilation housing 1 is open at one end facing the outer shell 202, forming the second air inlet 131. The second air outlet 2030 is provided at the end of the outer shell 202 facing the ventilation module 100, and the second air outlet 2030 is connected to the second air inlet 131.

[0077] In this way, the areas of the second air inlet 131 and the second air outlet 2030 are larger, which is beneficial to increasing the air volume of the ventilation module 100.

[0078] In some exemplary embodiments, the air conditioner can be, but is not limited to, a kitchen air conditioner, and can be used in a bathroom (bathroom air conditioner or located air conditioner) or in a kitchen (kitchen air conditioner). The ventilation module 100 can be located on one side of the air conditioner main body 200 in the longitudinal direction and connected to the air conditioner main body 200.

[0079] The air conditioner can be installed in the ceiling. Figure 2 and Figure 8 The up and down directions are based on the state of the air conditioner after it is concealed in the ceiling after leaving the factory, with the direction toward the ground being down and the direction toward the ceiling being up, with the motor base 3 at the top and the motor cover 4 at the bottom. However, during the assembly process before the air conditioner leaves the factory, the up and down directions may be changed, for example, with the motor base 3 at the bottom and the motor cover 4 at the top.
