[0030] The principles and features of the present application are described below with reference to the accompanying drawings. The examples given are only used to explain the present application and are not intended to limit the scope of the present application.

[0031] As Figures 1 to 6 shown, an embodiment of the present application provides a fresh air module, including: a housing 1, an electric control box 2, a volute component 3, and a sensor component 4.

[0032] The electric control box 2 is located outside the housing 1 and is connected to the housing 1.

[0033] The volute component 3 is arranged inside the housing 1, and a clamping portion is provided at the air inlet 325 of the volute component 3.

[0034] The sensor component 4 is fixed to the volute component 3 through the clamping portion and is electrically connected to the electric control box 2.

[0035] In the fresh air module provided by the embodiment of the present application, a clamping portion is arranged on the volute component 3, so that the sensor component 4 can be clamped and fixed on the volute component 3 through the clamping portion, and there is no need to fix the sensor component 4 with screws. Compared with the fastening structure, the clamping structure simplifies the installation structure of the sensor component 4, which is beneficial to improving the assembly efficiency of the fresh air module. And the sensor component 4 is arranged at the air inlet 325 of the volute component 3, so that the sensor component 4 is located near the air inlet 325, which is convenient for detecting information such as the temperature and humidity of the air entering the volute component 3.

[0036] In some exemplary embodiments, the sensor component 4 includes a humidity sensor, such as Figure 2 , Figure 3 and Figure 5 shown. The clamping portion includes a first buckle 321 (as Figure 6 shown), one end of the humidity sensor is in plug-in fit with the volute component 3, and the other end of the humidity sensor is clamped to the first buckle 321 to fix the humidity sensor to the volute component 3.

[0037] In this way, when assembling the humidity sensor, first plug one end of the humidity sensor into the volute component 3, and then clamp the other end of the humidity sensor to the first buckle 321, then the assembly of the humidity sensor can be completed. The operation is simple and fast, and the assembly efficiency is high.

[0038] In some exemplary embodiments, as Figure 4 and Figure 6 shown, the humidity sensor includes a box body 411 and a detection portion (not shown in the figure) arranged inside the box body 411. The box body 411 is provided with an air inlet hole 4111, as Figure 4 shown, which is convenient for air flow to enter the box body 411 and be detected by the detection portion.

[0039] Both ends of the box body 411 are respectively provided with a clamping protrusion 4112 and a tongue 4113, as Figure 6 shown. The volute component 3 is provided with a slot 3244 (as Figure 6As shown in FIG. 3 , the protrusion 4112 is engaged with the first buckle 321 , and the inserting tongue 4113 is inserted into the slot 3244 .

[0040] The specific structures of the protrusion 4112 and the tongue 4113 are not limited, and can be in various shapes such as plate, block, column, etc., as long as they can respectively match with the first buckle 321 and the slot 3244. Similarly, the shapes of the first buckle 321 and the slot 3244 are also not limited.

[0041] Of course, the positions of the first buckle 321 and the cam 4112 can also be exchanged, and the first buckle 321 is arranged on the box body 411, and the cam 4112 is arranged on the volute assembly 3, which can also achieve the snap-fitting of the box body 411 and the volute assembly 3. Similarly, the positions of the plug tongue 4113 and the slot 3244 can also be exchanged, and the plug tongue 4113 is arranged on the volute assembly 3, and the slot 3244 is arranged on the box body 411, which can also achieve the plug-fitting of the box body 411 and the volute assembly 3.

[0042] The matching form of the snap-fit structure is not limited to the first snap 321 and the snap convex 4112, and can be adjusted as needed. The matching form of the plug-in structure is not limited to the plug tongue 4113 and the slot 3244, and can be adjusted as needed.

[0043] In some exemplary embodiments, the box body 411 is provided with a first wiring gap 4114, such as Figure 4 As shown, a limit buckle 4115 is provided at the first wiring gap 4114. The wire body of the humidity sensor (referred to as the first wire body 42) is passed through the first wiring gap 4114. The limit buckle 4115 is configured to limit the wire body of the humidity sensor from escaping from the first wiring gap 4114. This facilitates wiring between the humidity sensor and the electric control box 2.

[0044] In some exemplary embodiments, the protrusion 4112 and the tongue 4113 are arranged at intervals along the length of the box body 411. The volute assembly 3 is provided with a first limit portion 3241 and a second limit portion 3242 arranged at intervals along the width direction of the box body 411. Figure 4 and Figure 6 The first limiting portion 3241 and the second limiting portion 3242 are engaged with both ends of the box body 411 in the width direction to limit the box body 411 from moving relative to the volute assembly 3 along the width direction of the box body 411 .

[0045] In this way, due to the stopping effect of the first limiting portion 3241 and the second limiting portion 3242, the position of the humidity sensor is more stable and is not prone to vibration, shaking, etc. under the impact of airflow, which is beneficial to improving the reliability of the humidity sensor.

[0046] Among them, the structural forms of the first limiting portion 3241 and the second limiting portion 3242 are not limited, and may be, but are not limited to, structures such as limiting ribs, limiting convex hulls, and limiting bumps. The width direction of the box body 411 may be substantially the same as the radial direction of the volute assembly 3.

[0047] In some exemplary embodiments, the sensor assembly 4 includes a temperature sensor 41 (not shown in the figure). The clamping portion includes a second buckle 322. As Figure 4 shown, the second buckle 322 is provided with a clamping hole 3221, and the temperature sensor 41 is inserted through the clamping hole 3221 and limited to the second buckle 322.

[0048] The temperature sensor 41 has a relatively small size and is generally in a columnar structure, and can be directly clamped on the second buckle 322, and the installation is very convenient. The second buckle 322 can fix the temperature sensor 41 by, but not limited to, an interference fit method.

[0049] In some exemplary embodiments, the clamping hole 3221 is provided with an installation notch 3222. As Figure 4 shown, the installation notch 3222 allows the temperature sensor 41 to enter and exit the clamping hole 3221. The clamping hole 3221 can be generally in a cylindrical shape with a notch, which is convenient for the installation and disassembly of the temperature sensor 41.

[0050] In some exemplary embodiments, the volute assembly 3 is provided with a wire routing buckle 323. As Figure 4 shown, the wire body of the temperature sensor 41 (denoted as the second wire body 43) is limited to the wire routing buckle 323. This facilitates the wiring between the temperature sensor 41 and the electronic control box 2.

[0051] In some exemplary embodiments, the volute assembly 3 includes a volute 31 and a guide vane ring 32. As Figure 1 shown. One axial end of the volute is provided with an installation opening. The guide vane ring 32 is sleeved at the installation opening and encloses an air inlet 325 communicating with the installation opening. The clamping portion is provided on the guide vane ring 32 and is located between the air inlet 325 and the electronic control box 2. As Figure 1 shown.

[0052] In this way, the distance between the clamping portion and the electronic control box 2 is relatively close, and the distance between the sensor assembly 4 and the electronic control box 2 is also relatively close, which facilitates the connection of the lines between the sensor assembly 4 and the electronic control box 2.

[0053] In some exemplary embodiments, the guide vane ring is provided with a vertical plate 324. As Figure 4 shown, the vertical plate 324 and the guide vane ring enclose an installation groove 3243, and at least a part of the humidity sensor is located in the installation groove 3243. The vertical plate 324 is provided with a first buckle 321, a slot 3244, a first limiting portion 3241, and a second limiting portion 3242.

[0054] In some exemplary embodiments, the electronic control box 2 is fixed to the side wall of the housing 1, as Figure 1 shown. The side wall is provided with a second wire routing notch 112, as Figure 2 shown. The wire bodies of the sensor assembly 4 pass through the second wire routing notch 112 to be electrically connected to the electronic control box 2.

[0055] Among them, the number of the second wire routing notches 112 can be multiple. The wire bodies of the temperature sensor 41 and the humidity sensor can enter the electronic control box 2 from the same second wire routing notch 112, or can enter the electronic control box 2 from different second wire routing notches 112.

[0056] In some embodiments, a wire routing rubber part 13 is provided at the second wire routing notch 112, as Figure 2 shown. The wire routing rubber part 13 is beneficial to preventing wire cutting and is beneficial to improving the sealing performance at the second wire routing notch 112.

[0057] The shape of the second wire routing notch 112 is not limited and can be rectangular, arc-shaped or other shapes. The shape of the wire routing rubber part 13 is not limited and can be in the shape of a block, a column, etc.

[0058] In one embodiment, the wire routing rubber part 13 is in a hollow cylindrical shape, as Figure 2 shown, and is clamped at the second wire routing notch 112. The wire bodies of the sensor assembly 4 pass through the wire routing rubber part 13 and enter the electronic control box 2.

[0059] In some exemplary embodiments, the housing 1 includes a bottom plate (not shown in the figure), a side wall plate 11 and a cover plate (not shown in the figure). The bottom plate and the cover plate are arranged at intervals relatively and are connected to the side wall plate 11. The cover plate is arranged at intervals relatively to the air inlet 325 of the volute casing assembly 3. The side wall plate 11 is provided with a fresh air inlet 111 (as Figure 1 shown) and a fresh air outlet. The cover plate is provided with an exhaust air inlet. The volute 31 is provided with an openable and closable switching port and an openable and closable exhaust air outlet. The fresh air inlet 111 is arranged to be able to communicate with the air inlet 325 through the switching port. The fresh air inlet 111 is arranged to be able to communicate with one of the switching port and the exhaust air outlet to switch the air flow direction of the fresh air inlet 111. At the fresh air inlet 111, the fresh air outlet, the exhaust air inlet, the exhaust air outlet and the switching port, air valves can be respectively provided to control opening and closing.

[0060] 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 325 and the fresh air outlet are communicated in sequence to form a fresh air duct.

[0061] Based on the communication between the fresh air inlet 111 and the exhaust air outlet, the exhaust air inlet, the air inlet 325, the exhaust air outlet and the fresh air inlet 111 are communicated in sequence to form an exhaust air duct.

[0062] In this way, the fresh air module not only has a fresh air duct, but also has an exhaust duct. The fresh air duct can be used to discharge outdoor fresh air into the indoor space, and the exhaust duct can discharge indoor polluted air to the outdoor space, which is beneficial to enrich the functions of the fresh air module, enabling the fresh air module to have both a fresh air mode and an exhaust mode, and both the fresh air mode and the exhaust mode are beneficial to improving 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 exhaust mode, which is beneficial to enhancing the user experience of the air conditioner.

[0063] In some embodiments, the fresh air module further includes a filter assembly 5, as Figure 1 shown. The filter assembly 5 includes a filter bracket 51 fixed to the guide ring 32 and a filter 52 installed on the filter bracket 51. The filter 52 is arranged along the circumference of the air inlet 325 of the volute assembly 3 and is located between the fresh air inlet 111 and the air inlet 325, configured to filter the fresh air.

[0064] The embodiment of the present application also provides an air conditioner, including an air conditioner main body (not shown in the figure) and the fresh air module according to any one of the above embodiments, and the fresh air module is connected to the air conditioner main body.

[0065] The air conditioner provided by the embodiment of the present application includes the fresh air module according to any one of the above embodiments, and thus has all the above beneficial effects, which will not be elaborated herein.

[0066] In some embodiments, the air conditioner can be, but is not limited to, a ducted air conditioner. The fresh air module can be located on one side of the ducted air conditioner main body in the length direction and is connected to the ducted air conditioner main body.

[0067] Among them, Figure 1 the directions are based on the state after the ducted air conditioner is recessed into the ceiling after leaving the factory. The direction towards the ground is down, the direction towards the ceiling is up, the guide ring 32 is on the top, the filter 52 is on the bottom, the cover plate is on the bottom, and the bottom plate is on the top. However, during the assembly process before the ducted air conditioner leaves the factory, the up and down directions can be changed. For example, the guide ring 32 is on the bottom, the filter 52 is on the top, the bottom plate is on the bottom, and the cover plate is on the top. The filter 52 is installed on the filter bracket 51 of the guide ring 32, and then the cover plate is covered.
