[0026] The principles and features of the present application will be described below with reference to the drawings. The examples given are only used to explain the present application and are not intended to limit the scope of the present application.

[0027] As Figures 1 to 4 shown, an embodiment of the present application provides a fresh air module, including: a housing 1 and a damper assembly 2.

[0028] Among them, the housing 1 is provided with a fresh air inlet 111, as Figure 1 shown. The air valve assembly 2 is located outside the housing 1. The air valve assembly 2 includes a fixed bracket 21, a driving member 22 and an air valve 23.

[0029] The fixed bracket 21 is connected to the housing 1, and the fixed bracket 21 is provided with an air passage 213 communicating with the fresh air inlet 111, as Figure 2 shown. The fixed bracket 21 is an installation carrier for the driving member 22 and the air valve 23. The fixed bracket 21 may be provided with a structure for connecting to a fresh air pipeline, so as to communicate with the outside space through the fresh air pipeline.

[0030] As Figure 2 shown, the air valve 23 is located in the air passage 213 and is configured to control the on / off of the air passage 213. When the air valve 23 conducts the air passage 213, the fresh air inlet 111 can communicate with the outside space through the air passage 213, which is equivalent to opening the fresh air inlet 111. When the air valve 23 disconnects the air passage 213, the fresh air inlet 111 is disconnected from the outside space, which is equivalent to closing the fresh air inlet 111.

[0031] The driving member 22 is installed on the fixed bracket 21 and connected to the air valve 23, and is configured to drive the air valve 23 to move between an open position where the air passage 213 is conducted and a closed position where the air passage 213 is disconnected.

[0032] The air valve 23 may be, but is not limited to, a valve plate. The driving member 22 may be, but is not limited to, a stepping motor. The air valve 23 may be rotatably installed in the air passage 213. When the air valve 23 rotates to the open position, the plate surface of the air valve 23 is parallel to the central axis of the air passage 213. When the air valve 23 rotates to the closed position, the plate surface of the air valve 23 is perpendicular to the central axis of the air passage 213.

[0033] In the fresh air module provided by the embodiment of the present application, the air valve assembly 2 at the fresh air inlet 111 is transferred to the outside of the housing 1 of the fresh air module, so that the maintenance and replacement of the driving member 22 are not restricted by the housing 1 of the fresh air module. Therefore, when the driving member 22 of the air valve assembly 2 needs to be maintained and replaced, the driving member 22 can be directly maintained and replaced without first disassembling the whole fresh air module and then disassembling the housing 1 of the fresh air module, thereby reducing the difficulty of maintaining and replacing the driving member 22, improving the convenience of maintaining the driving member 22, and reducing the maintenance cost.

[0034] In some exemplary embodiments, such as Figure 2 and Figure 3As shown, the air valve assembly 2 further includes: a thermal insulation cover 24, sleeved outside the fixed bracket 21 and the driving member 22, and the thermal insulation cover 24 is provided with a maintenance notch 241, and the maintenance notch 241 is correspondingly arranged with the driving member 22.

[0035] The thermal insulation cover 24 can play a role in heat preservation for the fixed bracket 21 and the driving member 22, which is beneficial to preventing the driving member 22 from generating condensation, and is beneficial to improving the use reliability of the driving member 22. The setting of the maintenance notch 241 provides convenience for the maintenance of the driving member 22, and the driving member 22 will not be blocked due to the setting of the thermal insulation cover 24.

[0036] The material of the thermal insulation cover 24 is not limited, and it can be a thermal insulation foam part.

[0037] In some exemplary embodiments, as Figure 2 and Figure 3 shown, the air valve assembly 2 further includes: a protective cover 25, detachably installed at the maintenance notch 241, and enclosing an installation cavity for installing the driving member 22 with the fixed bracket 21.

[0038] When the driving member 22 needs to be maintained and replaced, the protective cover 25 can be removed, and the driving member 22 can be seen. When the maintenance and replacement are completed, the protective cover 25 can be reinstalled.

[0039] The protective cover 25 can play a role in protecting the driving member 22 on the one hand, and can play a role in heat preservation for the driving member 22 on the other hand, which is beneficial to further reducing the risk of condensation of the driving member 22, and thus is beneficial to improving the use reliability of the driving member 22.

[0040] In some exemplary embodiments, as Figure 2 and Figure 3 shown, a positioning sunk groove 242 is provided at the maintenance notch 241, and at least part of the protective cover 25 is located in the positioning sunk groove 242 and is in abutting fit with the groove bottom 2421 of the positioning sunk groove 242. This can play a role in positioning the assembly of the protective cover 25 and is beneficial to improving the assembly efficiency.

[0041] In some exemplary embodiments, as Figure 3 shown, the outer side wall of the fixed bracket 21 is provided with a first connecting column 211 and a second connecting column 212, the driving member 22 is fixedly connected to the first connecting column 211 through a fastener, and the protective cover 25 is fixedly connected to the second connecting column 212 through a fastener. The fastener has a high connection strength and is relatively firmly fixed. The fastener can be, but is not limited to, a screw.

[0042] The number of the first connecting columns 211 is not limited, and can be one or multiple. The number of the second connecting columns 212 is not limited, and can be one or multiple.

[0043] In one embodiment, the driving member 22 is fixedly connected to the fixed bracket 21 by two fasteners. The protective cover 25 is fixedly connected to the fixed bracket 21 by one fastener. An avoidance groove 251 is provided at one end of the protective cover 25 facing away from the fixed bracket 21, and the head of the fastener is received in the avoidance groove 251 to prevent protrusion and increase the space occupied by the air valve assembly 2.

[0044] In some exemplary embodiments, as Figure 3 shown, one end of the fixed bracket 21 close to the housing 1 is provided with a first connecting plate 214. One end of the heat preservation cover 24 close to the housing 1 is provided with a second connecting plate 243. The first connecting plate 214 is attached to the second connecting plate 243 and is fixedly connected to the housing 1 by a fastener.

[0045] This makes the structures of the fixed bracket 21 and the heat preservation cover 24 relatively regular, facilitating reliable connection to the housing 1 through fasteners.

[0046] As Figure 3 shown, the outer contours of the first connecting plate 214 and the second connecting plate 243 can be rectangular. The number of fasteners can be four. The four fasteners are located at the four corners of the rectangle. The first connecting plate 214 and the second connecting plate 243 are respectively provided with four connecting holes. The four fasteners connect the first connecting plate 214, the second connecting plate 243 and the housing 1 together, with reliable fixation and uniform force.

[0047] In some exemplary embodiments, as Figure 1 shown, the housing 1 includes a first side plate 11 and a second side plate 12 arranged adjacent to each other. The fresh air inlet 111 is provided on the first side plate 11, and the second side plate 12 is provided with a fresh air outlet 121. In the thickness direction of the second side plate 12 (i.e., Figure 1 the front-back direction in

[0048] ), the driving member 22 is located on the side of the fresh air inlet 111 close to the fresh air outlet 121 (i.e., on the front side of the fresh air inlet 111).

[0049] The fresh air outlet 121 is usually arranged forward for forward air outlet. Therefore, the driving member 22 is also located on the front side of the fresh air inlet 111 and will not be blocked by the fixed bracket 21, facilitating the operator to perform maintenance and replacement on it.

[0050] And, for the fresh air module located in the ceiling, the ceiling usually has an air outlet grille corresponding to the fresh air outlet 121. The projection of the driving member 22 on the air outlet grille can be located within the air outlet grille. Then, by removing the air outlet grille, a maintenance opening can be exposed, and the driving member 22 can be maintained and replaced through the maintenance opening, which is very convenient. Figure 1As shown, the housing 1 may further include a third side plate 15, a fourth side plate 16, a bottom plate 14 and a cover plate 13. The first side plate 11, the second side plate 12, the third side plate 15 and the fourth side plate 16 are connected end to end in sequence to enclose a quadrangular prism structure. The bottom plate 14 and the cover plate 13 are respectively disposed at the two open ends of the quadrangular prism. An air exhaust inlet 131 may be provided on the cover plate 13.

[0051] The fresh air module may further include a volute (not shown in the figure). The volute is provided with an air inlet, an openable and closable switching port and an openable and closable air exhaust outlet. The fresh air inlet 111 is arranged to be communicable with the air inlet through the switching port. The fresh air inlet 111 is arranged to be communicable with either the switching port or the air exhaust outlet to switch the air flow direction of the fresh air inlet 111. Air valves 23 may be respectively provided at the fresh air outlet 121, the air exhaust inlet 131, the air exhaust outlet and the switching port to control opening and closing.

[0052] Based on the communication between the fresh air inlet 111 and the switching port, the fresh air inlet 111, the switching port, the air inlet and the fresh air outlet 121 are sequentially communicated to form a fresh air duct.

[0053] Based on the communication between the fresh air inlet 111 and the air exhaust outlet, the air exhaust inlet 131, the air inlet, the air exhaust outlet and the fresh air inlet 111 are sequentially communicated to form an air exhaust duct.

[0054] In this way, the fresh air module not only has a fresh air duct, but also has an air exhaust duct. The fresh air duct can be used to discharge outdoor fresh air into the indoor space, and the air exhaust duct can discharge indoor polluted air to the outdoor space, which is beneficial to enrich the functions of the fresh air module, so that the fresh air module has both a fresh air mode and an air exhaust mode, and both the fresh air mode and the air exhaust mode are beneficial to improving the air quality. In this way, when the air quality is good, the indoor air quality can be improved through the fresh air mode; when the outdoor air quality is poor, the indoor air quality can be improved through the air exhaust mode, which is beneficial to improving the use experience of the air conditioner.

[0055] In some exemplary embodiments, as Figure 1 shown, the fresh air module further includes an electric control box 3. The electric control box 3 is fixed to the first side plate 11. In the thickness direction of the second side plate 12 (i.e., Figure 1 the front-back direction in Figure 4 ), the electric control box 3 is located on the side of the fresh air inlet 111 away from the second side plate 12 (i.e., behind the fresh air inlet 111). The electric control box 3 is provided with a wire inlet 31. As

[0056] shown, the fixing bracket 21 is provided with a wire groove 2143, and the wire groove 2143 is communicated with the wire inlet 31. The wire body of the driving member 22 is arranged to pass through the wire groove 2143 and the wire inlet 31 and enter the electric control box 3. This facilitates the connection of the circuit between the driving member 22 and the electric control box 3.

[0056] In some exemplary embodiments, as Figure 4As shown, a flange 2141 and a guide rib 2142 are provided at one end of the fixing bracket 21 close to the housing 1, and a wiring groove 2143 is formed between the flange 2141 and the guide rib 2142. The notch of the wiring groove 2143 faces the first side plate 11, so the opening of the wiring groove 2143 can be blocked by the first side plate 11, which is helpful to prevent the wire body of the driving member 22 from being damaged by being bitten by mice or affected by other external debris.

[0057] The driving member 22 is located on the side of the wiring groove 2143 away from the first side plate 11. The fixing bracket 21 is also provided with a wire-passing notch 2145 connected to the wiring groove 2143. Figure 4 As shown, the wire notch 2145 passes through the bottom of the wiring groove 2143 , which makes it easy for the wire body of the driving member 22 to enter the wiring groove 2143 .

[0058] Among them, Figure 4 As shown, the flange 2141 and the guide rib 2142 can be arranged on the first connecting plate 214 of the fixing bracket 21. The flange 2141 can be arranged along the circumference of the first connecting plate 214. The guide rib 2142 can be a continuous rib or a discontinuous rib. The wiring groove 2143 can be located at a relatively lower position of the first connecting plate 214. The wire inlet 31 can be located at the bottom of one end of the electric control box 3 close to the air valve assembly 2.

[0059] In some exemplary embodiments, Figure 4 As shown, a wire buckle 2144 is provided in the wire routing groove 2143 , which is helpful to improve the position stability of the wire body of the driving member 22 .

[0060] An embodiment of the present application also provides an air conditioner, comprising an air conditioner main body (not shown in the figure) and a fresh air module of any one of the above embodiments, wherein the fresh air module is connected to the air conditioner main body.

[0061] The air conditioner provided in the embodiment of the present application includes the fresh air module of any one of the above embodiments, and thus has all the above beneficial effects, which will not be elaborated here.

[0062] In some embodiments, the air conditioner may be, but is not limited to, a duct air conditioner. The fresh air module may be located at one side of the length direction of the duct air conditioner body and connected to the duct air conditioner body.
