[0034] 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.

[0035] like Figures 1 to 7 As shown, an embodiment of the present application provides a ventilation module 100 , comprising: a ventilation housing 1 , an air outlet pipe connector 2 , a mounting bracket 3 and a volute 4 .

[0036] The ventilation housing 1 is provided with a ventilation outlet 111. Figure 7 The air outlet pipe joint 2 is located outside the ventilation housing 1 and is fixed to the ventilation housing 1 , and the air outlet pipe joint 2 is connected to the ventilation outlet 111 .

[0037] like Figure 5 As shown, the mounting bracket 3 is located in the ventilation housing 1 and is fixed to the ventilation housing 1, and the mounting bracket 3 is provided with an avoidance opening corresponding to the ventilation outlet 111. Figure 4 shown.

[0038] like Figure 5 As shown, the volute 4 is located in the ventilation housing 1 and is fixed to the mounting bracket 3. The outlet of the volute 4 is communicated with the ventilation outlet 111 through the avoidance opening.

[0039] The ventilation module 100 provided in the embodiment of the present application incorporates a mounting bracket 3 within the ventilation housing 1, allowing the volute 4 and the air outlet pipe connector 2 to be fixed to the mounting bracket 3 and the ventilation housing 1, respectively. This helps prevent the volute 4 and the air outlet pipe connector 2 from overlapping and causing a failure in the fixation, thereby improving the reliability of the ventilation module 100. Furthermore, the mounting bracket 3 enhances the structural strength of the area surrounding the ventilation outlet 111, thereby improving the securement and operational reliability of the air outlet pipe connector 2 and the volute 4.

[0040] In some exemplary embodiments, Figure 2 As shown, a ventilation fan 6 is further provided in the heat exchange housing. The ventilation fan 6 includes a wind wheel 61 located in the volute 4 and a wind wheel motor 62 connected to the wind wheel 61. Figure 3The wind wheel motor 62 drives the wind wheel 61 to rotate, sucking the indoor air into the ventilation housing 1 and exhausting it to the outside through the ventilation outlet 111, thus realizing the ventilation function.

[0041] In some exemplary embodiments, Figure 5 As shown, the volute 4 is provided with a connecting fold 43 , and the connecting fold 43 is fixedly connected to the mounting bracket 3 .

[0042] The body of the volute 4 can form a volute-shaped air duct to accommodate components such as the wind wheel 61. The connecting fold 43 is convenient for fitting with the mounting bracket 3 to reduce the difficulty of assembling the volute 4 and the mounting bracket 3.

[0043] In some exemplary embodiments, the connecting fold 43 is provided with a snap-fit ​​portion, and the mounting bracket 3 is provided with a snap-fit ​​portion. The snap-fit ​​portion and the snap-fit ​​portion are engaged with each other to locate the relative positions of the volute 4 and the mounting bracket 3.

[0044] like Figure 4 As shown, the connecting flange 43 is provided with a first connecting hole 435, and the mounting bracket 3 is provided with a second connecting hole 312. Fasteners are passed through the first connecting hole 435 and the second connecting hole 312 to fix the volute 4 to the mounting bracket 3.

[0045] In this way, the volute 4 and the mounting bracket 3 can be positioned first by the snap-fit ​​structure and then fixed by fasteners (such as screws), which not only improves assembly efficiency but also ensures fixation reliability. In addition, the snap-fit ​​structure can act as a limiter, thereby reducing the number of fasteners used to fix the volute 4, thereby reducing the difficulty of installing the volute 4 and improving assembly efficiency.

[0046] In some exemplary embodiments, one of the snap-fit ​​portion and the snap-fit ​​portion includes a snap 434 (e.g., Figure 4 ), the other includes a card slot 311 (as shown Figure 4 As shown), the buckle 434 is inserted into the slot 311.

[0047] Of course, the structural form of the snap-fitting portion and the snap-fitting fitting portion is not limited to the snap 434 and the slot 311 , and may also be a snap hook and a snap hole, a snap 434 and a snap bulge, and other structural forms, which are not listed here one by one.

[0048] In some embodiments, the buckle 434 is provided with a limiting rib, and the limiting rib is configured to press tightly against the slot wall of the slot 311 to limit the buckle 434 from falling out of the slot 311 .

[0049] Alternatively, the buckle 434 is provided with a hook portion, which is configured to pass through the slot 311 and hook the notch of the slot 311 to limit the buckle 434 from escaping from the slot 311 .

[0050] The provision of the limiting rib or hook enables the buckle 434 to be firmly inserted into the slot 311 , so that the buckle 434 is not easily dislodged when the ventilation module 100 is hoisted, which is beneficial to improving the connection reliability between the volute 4 and the mounting bracket 3 .

[0051] The buckle 434 can be an elastic buckle 434. Figure 4 As shown, there may be multiple elastic clips 434 , which are symmetrically distributed to improve the connection reliability between the volute 4 and the mounting bracket 3 .

[0052] In some exemplary embodiments, Figure 5 As shown, the connecting edge 43 includes a first edge 431, a second edge 432, and a third edge 433. The first edge 431 and the third edge 433 are spaced apart on both sides of the second edge 432 along the axial direction of the volute 4. A first connecting hole 435 is provided in the second edge 432, and a clamping portion is provided in the first edge 431 and the third edge 433.

[0053] The first folded edge 431 and the third folded edge 433 can be symmetrically arranged. The first connecting hole 435 can be one, located in the middle of the second folded edge 432. This facilitates force balance between the volute 4 and the mounting bracket 3. The second folded edge 432 can be a continuous folded plate. The first folded edge 431 and the third folded edge 433 can be discontinuous folded plates, each having a plurality of notches to avoid the snap-fitting portion on the mounting bracket 3. These notches can form the snap-fitting slots 311, or they can simply be used to avoid the snap-fitting portion.

[0054] In some exemplary embodiments, Figure 3 As shown, the volute 4 includes a first sub-case 41 and a second sub-case 42. The first sub-case 41 is fixed to the mounting bracket 3. The second sub-case 42 is covered on the first sub-case 41 and is detachably connected to the first sub-case 41.

[0055] The volute 4 is provided as a split structure to facilitate the installation of the internal structure (such as the wind wheel 61). The outlet of the volute 4 can be provided in the first sub-shell 41, or can be enclosed by the first sub-shell 41 and the second sub-shell 42.

[0056] The first sub-shell 41 and the second sub-shell 42 can be detachably fixedly connected by fasteners (such as screws), snap-fitting, etc. The first sub-shell 41 is provided with the above-mentioned connecting flange 43 .

[0057] The first sub-case 41 and the second sub-case 42 can be separated in the radial direction of the volute 4, and the second sub-case 42 can be arranged on the first sub-case 41 in the radial direction of the volute 4. During the assembly process before leaving the factory, the second sub-case 42 can be at the bottom (thus, it can be called the lower volute) and the first sub-case 41 can be at the top (thus, it can be called the upper volute). In the assembled state after leaving the factory, such as the hoisting state, the second sub-case 42 is at the top and the first sub-case 41 is at the bottom.

[0058] In some exemplary embodiments, Figure 5 As shown, the mounting bracket 3 includes a bracket body 31 and a flange 32 connected to the bracket body 31. The flange 32 is welded and fixed to the inner wall of the ventilation housing 1. The volute 4 is fixed to the bracket body 31.

[0059] The flange 32 is welded and fixed to the inner wall of the ventilation shell 1 to form an integrated structure, which is beneficial to improving the connection strength between the ventilation shell 1 and the mounting bracket 3, and is also beneficial to improving the structural strength of the area around the ventilation outlet 111, thereby helping to improve the fixation reliability and use reliability of the volute 4 and the air outlet pipe joint 2.

[0060] The thickness of the bracket body 31 may be greater than the thickness of the flange 32 to improve the strength of the mounting bracket 3 and provide installation space for fasteners used to fix the volute 4 .

[0061] Of course, the mounting bracket 3 and the ventilation housing 1 can also be fixedly connected by fasteners or integrally formed.

[0062] In some exemplary embodiments, the mounting bracket 3 is a sheet metal part, and the ventilation housing 1 may also be a sheet metal part. Sheet metal parts have high structural strength and are easy to fix by welding.

[0063] In some exemplary embodiments, Figure 3 As shown, the ventilation module 100 further includes: an air valve 5, which is provided in the air outlet pipe joint 2 and is configured to open or close the ventilation outlet 111. The air valve 5 can open or close the ventilation outlet 111 by rotating, sliding, or the like.

[0064] In some embodiments, the damper 5 can be driven by a driver (such as a motor for the damper 5). However, the driver's cable needs to pass through the ventilation housing 1, which is inconvenient to route and difficult to protect, which can easily lead to failure of the driver.

[0065] In other embodiments, the air valve 5 is rotatably connected to the air outlet pipe connector 2, and the position of the rotation axis of the air valve 5 is higher than the center of gravity of the air valve 5, so that the air valve 5 can be rotated to a position where the ventilation outlet 111 is opened under the action of the air flow (such as Figure 7 As shown), it rotates to a position where the ventilation outlet 111 is closed under the action of gravity (as shown Figure 6shown).

[0066] In this way, the driving components such as the damper 5 motor for driving the damper 5 to move can be omitted, thereby reducing the cost of the ventilation module 100 and avoiding the problems of inconvenient wiring and poor protection of the driving components.

[0067] In some embodiments, the rotation axis of the air valve 5 is located at the top of the air valve 5 . When the air valve 5 closes the ventilation outlet 111 , the air valve 5 is tilted and tilted outward from top to bottom.

[0068] This helps to reduce the rotation amplitude of the air valve 5 from the closed position to the open position, thereby helping to reduce the resistance of the air valve 5 to the air flow and improving the reliability of the air valve 5.

[0069] In some embodiments, when the air valve 5 closes the ventilation outlet 111, the inclination angle of the air valve 5 relative to the gravity direction can be in the range of but not limited to 15° to 20°, such as 15°, 16°, 17°, 18°, 19°, 20°, etc.

[0070] This is beneficial to avoid the air valve 5 being tilted too much, resulting in an excessively large area of ​​the air valve 5, and is also beneficial to avoid the air valve 5 being tilted too little, resulting in an excessively large opening resistance of the air valve 5.

[0071] In some exemplary embodiments, Figure 3 and Figure 5 As shown, the ventilation housing 1 includes a bottom plate 12 and a side plate 11 connected to the bottom plate 12, the ventilation outlet 111 is provided on the side plate 11, the mounting bracket 3 is fixed to the side plate 11, the air outlet pipe joint 2 is fixed to the outer wall of the side plate 11, and the mounting bracket 3 is fixed to the inner wall of the side plate 11.

[0072] In some exemplary embodiments, the air outlet pipe connector 2 is fixedly connected to the ventilation housing 1 by a first fastener, and the volute 4 is fixedly connected to the mounting bracket 3 by a second fastener. In addition, the first fastener and the second fastener are staggered along the circumference of the ventilation outlet 111.

[0073] This can effectively avoid the first fastener and the second fastener from interfering with each other. The number of the first fastener can be multiple, and the number of the second fastener can be one.

[0074] The ventilation outlet 111 may be rectangular. The air outlet pipe joint 2 may include a rectangular flange edge 21, such as Figure 6 As shown, the number of the first fasteners may be four, and the four first fasteners are located at the four corners of the flange edge 21 .

[0075] In some exemplary embodiments, the lower end of the ventilation housing 1 is open, and the ventilation module 100 further includes a cover plate 7. Figure 3 As shown, the cover plate 7 is disposed on the lower end of the ventilation housing 1 and is detachably connected to the ventilation housing 1 .

[0076] The cover plate 7 can be used as an inspection panel of the ventilation module 100. When the internal structure of the ventilation module 100 needs to be inspected, the cover plate 7 can be removed to inspect the ventilation fan 6 and other components of the ventilation module 100.

[0077] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, an embodiment of the present application further 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 .

[0078] 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.

[0079] 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.

[0080] 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.

[0081] like 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 a ventilation outlet 111. The second air inlet 131 is connected to the second air outlet 2030. The ventilation outlet 111 can be connected to the outdoor space through an exhaust duct.

[0082] 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 6 is configured to generate an airflow from the first air inlet 2026 to the second air outlet 2030.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] In some exemplary embodiments, the air conditioner can be, but is not limited to, a kitchen or bathroom air conditioner and can be used in a bathroom (bathroom air conditioner or bathroom air conditioner) or 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. The air inlet of the volute 4 of the ventilation module 100 can be connected to the return air outlet of the air conditioner main body 200, and indoor air is drawn into the ventilation housing 1 through the return air outlet and then discharged to the outside through the volute 4 and the ventilation outlet 111.

[0089] The air conditioner can be installed in the ceiling. Figure 2 、 Figure 4 、 Figure 6 and Figure 7The up and down directions are based on the air conditioner's factory-installed concealed ceiling state, with the ground facing down and the ceiling facing up. The cover plate 7 is at the bottom, with the ventilation housing 1 at the top. However, during the factory assembly process, the up and down directions can be changed. For example, the ventilation housing 1 can be at the bottom, with the cover plate 7 at the top. The volute 4, impeller 61, impeller motor 62, and other components can be installed in the ventilation housing 1, and then the cover plate 7 can be installed.
