[0034] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0035] like Figures 1 to 6 As shown in the figure, this application provides a fresh air module, including: a housing 1, an electrical control box 2, a volute assembly 3, and a sensor assembly 4.

[0036] The electrical control box 2 is located outside the housing 1 and is connected to the housing 1.

[0037] The volute assembly 3 is located inside the housing 1, and a snap-fit ​​part is provided at the air inlet 325 of the volute assembly 3.

[0038] The sensor assembly 4 is fixed to the volute assembly 3 by a snap-fit ​​part and is electrically connected to the electronic control box 2.

[0039] The fresh air module provided in this application embodiment has a snap-fit ​​part on the volute assembly 3, which allows the sensor assembly 4 to be snapped and fixed to the volute assembly 3 without the need for screws. Compared to a fastener fixing structure, the snap-fit ​​structure simplifies the installation structure of the sensor assembly 4 and improves the assembly efficiency of the fresh air module. Furthermore, placing the sensor assembly 4 at the air inlet 325 of the volute assembly 3 facilitates the detection of information such as temperature and humidity of the air entering the volute assembly 3.

[0040] In some exemplary embodiments, sensor component 4 includes a humidity sensor, such as... Figure 2 , Figure 3 and Figure 5 As shown. The snap-fit ​​part includes a first snap-fit ​​321 (as shown). Figure 6 As shown, one end of the humidity sensor is inserted into the volute assembly 3, and the other end of the humidity sensor is snapped into the first buckle 321 to fix the humidity sensor to the volute assembly 3.

[0041] In this way, when assembling the humidity sensor, one end of the humidity sensor is first inserted into the volute assembly 3, and then the other end of the humidity sensor is snapped into the first clip 321 to complete the assembly of the humidity sensor. The operation is simple, quick and efficient.

[0042] In some exemplary embodiments, such as Figure 4 and Figure 6 As shown, the humidity sensor includes a housing 411 and a detection unit (not shown) disposed within the housing 411. The housing 411 is provided with an air inlet 4111, such as... Figure 4 As shown, this facilitates the airflow entering the housing 411 and being detected by the detection unit.

[0043] The two ends of the box body 411 are respectively provided with a latching protrusion 4112 and a tongue 4113, such as Figure 6 As shown. The volute assembly 3 is provided with slot 3244 (as shown). Figure 6 As shown), the protrusion 4112 is engaged with the first buckle 321, and the tongue 4113 is inserted into the slot 3244.

[0044] The specific structure of the latch 4112 and the tongue 4113 is not limited; they can be plate-shaped, block-shaped, column-shaped, or any other shape, as long as they can respectively mate with the first latch 321 and the slot 3244. Similarly, the shapes of the first latch 321 and the slot 3244 are also not limited.

[0045] Of course, the positions of the first latch 321 and the latch protrusion 4112 can also be interchanged, with the first latch 321 placed on the housing 411 and the latch protrusion 4112 placed on the volute assembly 3, which can also achieve the snap-fit ​​engagement between the housing 411 and the volute assembly 3. Similarly, the positions of the tongue 4113 and the slot 3244 can also be interchanged, with the tongue 4113 placed on the volute assembly 3 and the slot 3244 placed on the housing 411, which can also achieve the insertion engagement between the housing 411 and the volute assembly 3.

[0046] The engagement form of the snap-fit ​​structure is not limited to the first snap-fit ​​321 and the snap-fit ​​protrusion 4112; for example, it can also be a snap hook and a snap hole 3221, which can be adjusted as needed. The engagement form of the plug-in structure is not limited to the plug tongue 4113 and the slot 3244; for example, it can also be a snap buckle and a plug hole, which can be adjusted as needed.

[0047] In some exemplary embodiments, the housing 411 is provided with a first wiring notch 4114, such as... Figure 4 As shown, a limiting buckle 4115 is provided at the first wiring notch 4114. The wire of the humidity sensor (denoted as the first wire 42) passes through the first wiring notch 4114. The limiting buckle 4115 is configured to prevent the wire of the humidity sensor from coming out of the first wiring notch 4114. This facilitates the wiring between the humidity sensor and the electrical control box 2.

[0048] In some exemplary embodiments, the latch 4112 and the tongue 4113 are spaced apart along the length of the housing 411. The volute assembly 3 is provided with a first limiting portion 3241 and a second limiting portion 3242 spaced apart along the width direction of the housing 411, such as... Figure 4 and Figure 6 As shown. The first limiting part 3241 and the second limiting part 3242 are engaged with the two ends of the box body 411 in the width direction to restrict the movement of the box body 411 relative to the volute assembly 3 in the width direction of the box body 411.

[0049] Thus, due to the stopping effect of the first limiting part 3241 and the second limiting part 3242, the position of the humidity sensor is more stable and less prone to vibration or shaking under the impact of airflow, which helps to improve the reliability of the humidity sensor.

[0050] The structural forms of the first limiting part 3241 and the second limiting part 3242 are not limited, and can be, but are not limited to, limiting ribs, limiting protrusions, limiting protrusions, etc. The width direction of the box body 411 can be basically consistent with the radial direction of the volute assembly 3.

[0051] In some exemplary embodiments, sensor assembly 4 includes a temperature sensor 41 (not shown). The snap-fit ​​portion includes a second snap 322, such as... Figure 4 As shown, the second buckle 322 has a buckle hole 3221, and the temperature sensor 41 passes through the buckle hole 3221 and is confined in the second buckle 322.

[0052] The temperature sensor 41 is relatively small in size and roughly cylindrical in shape, allowing it to be directly snapped onto the second clip 322, making installation very convenient. The second clip 322 can, but is not limited to, secure the temperature sensor 41 by an interference fit.

[0053] In some exemplary embodiments, the slot 3221 is provided with an installation notch 3222, such as Figure 4 As shown, the mounting notch 3222 allows the temperature sensor 41 to enter and exit the slot 3221. The slot 3221 can be roughly cylindrical with a notch, facilitating the installation and removal of the temperature sensor 41.

[0054] In some exemplary embodiments, the volute assembly 3 is provided with a wiring clip 323, such as... Figure 4 As shown, the wire of temperature sensor 41 (denoted as the second wire 43) is confined to the wiring clip 323. This facilitates the wiring between temperature sensor 41 and electrical control box 2.

[0055] In some exemplary embodiments, the volute assembly 3 includes a volute 31 and a guide ring 32, such as Figure 1 As shown. The volute has an axial installation opening at one end. A guide ring 32 is fitted onto the installation opening, forming an air inlet 325 that communicates with the installation opening. A snap-fit ​​part is located on the guide ring 32, between the air inlet 325 and the electrical control box 2, as shown. Figure 1 As shown.

[0056] In this way, the proximity between the snap-fit ​​part and the control box 2 also makes the proximity between the sensor assembly 4 and the control box 2 easier to connect the wiring between them.

[0057] In some exemplary embodiments, the guide ring 32 is provided with a vertical plate 324, such as Figure 4 As shown, the upright plate 324 and the guide ring 32 together form a mounting groove 3243, and at least a portion of the humidity sensor is located within the mounting groove 3243. The upright plate 324 is provided with a first buckle 321, a slot 3244, a first limiting part 3241, and a second limiting part 3242.

[0058] In some exemplary embodiments, the electrical control box 2 is fixed to the side wall of the housing 1, such as... Figure 1 As shown. A second wiring notch 112 is provided on the side wall, as... Figure 2 As shown, the wires of the sensor assembly 4 are threaded through the second wiring notch 112 to be electrically connected to the control box 2.

[0059] There can be multiple second wiring notches 112. The wires of the temperature sensor 41 and the humidity sensor can enter the electrical control box 2 from the same second wiring notch 112 or from different second wiring notches 112.

[0060] In some embodiments, a wiring rubber component 113 is provided at the second wiring notch 112, such as... Figure 2 As shown. The wiring rubber component 113 helps prevent wire cutting and improves the sealing at the second wiring notch 112.

[0061] The shape of the second wiring notch 112 is not limited; it can be rectangular, arc-shaped, or other shapes. The shape of the wiring rubber part 113 is not limited; it can be block-shaped, column-shaped, or other shapes.

[0062] In one embodiment, the wiring rubber component 113 is a hollow cylinder, such as... Figure 2As shown, the sensor assembly 4 is stuck at the second wiring notch 112, and the wire passes through the wiring rubber part 113 and enters the electrical control box 2.

[0063] In some exemplary embodiments, the housing 1 includes a base plate (not shown), side panels 11, and a cover plate (not shown). The base plate and the cover plate are spaced apart from each other and connected to the side panels 11. The cover plate is spaced apart from the air inlet 325 of the volute assembly 3. The side panels 11 are provided with a fresh air inlet 111 (e.g., Figure 1 As shown in the diagram, the cover plate has an exhaust inlet, and the volute 31 has an openable / closable switching port and an openable / closable exhaust outlet. The fresh air inlet 111 is configured to connect to the air inlet 325 via the switching port. The fresh air inlet 111 is configured to connect to either the switching port or the exhaust outlet to switch the airflow direction of the fresh air inlet 111. Air valves can be installed at the fresh air inlet 111, fresh air outlet, exhaust inlet, exhaust outlet, and switching port to control their opening and closing.

[0064] Based on the connection between the fresh air inlet 111 and the switching port, the fresh air inlet 111, the switching port, the air inlet 325, and the fresh air outlet are connected in sequence to form a fresh air duct.

[0065] Based on the connection between the fresh air inlet 111 and the exhaust outlet, the exhaust inlet, air inlet 325, exhaust outlet, and fresh air inlet 111 are connected in sequence to form an exhaust duct.

[0066] Thus, the fresh air module not only has a fresh air duct but also an exhaust duct. The fresh air duct is used to bring fresh outdoor air into the indoor space, while the exhaust duct can expel stale indoor air to the outside. This enriches the functionality of the fresh air module, allowing it to have both a fresh air mode and an exhaust mode, both of which contribute to improving air quality. Therefore, when air quality is good, the fresh air mode can be used to improve indoor air quality; when outdoor air quality is poor, the exhaust mode can be used to improve indoor air quality, thereby enhancing the user experience of the air conditioner.

[0067] In some embodiments, the fresh air module further includes a filter assembly 5, such as Figure 1 As shown, the filter assembly 5 includes a filter bracket 51 fixed to the air guide ring 32 and a filter 52 installed on the filter bracket 51. It is located between the fresh air inlet 111 and the air inlet 325 and is configured to filter the fresh air.

[0068] This application also provides an air conditioner, including an air conditioner body (not shown in the figure) and a fresh air module of any of the above embodiments, wherein the fresh air module is connected to the air conditioner body.

[0069] The air conditioner provided in this application embodiment includes a fresh air module of any of the above embodiments, and therefore has all the above-mentioned beneficial effects, which will not be repeated here.

[0070] In some embodiments, the air conditioner may be, but is not limited to, a ducted air conditioner. The fresh air module may be located on one side of the length of the ducted air conditioner body and connected to the ducted air conditioner body.

[0071] in, Figure 1 The orientation of the ducted air conditioner is based on its concealed installation in the ceiling after leaving the factory. The direction facing the ground is considered down, and the direction facing the ceiling is considered up. The air guide ring 32 is on top, the filter 52 is on the bottom, the cover plate is on top, and the base plate is on the bottom. However, during the assembly process before the ducted air conditioner leaves the factory, the orientation can be changed. For example, the air guide ring 32 can be on the bottom, the filter 52 on top, the base plate on top, and the cover plate on the bottom. The filter 52 can be installed on the filter support 51 of the air guide ring 32, and then the cover plate can be placed on top.
