[0050] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0051] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0052] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time.

[0053] Currently, when using an air conditioner at home, in order to ensure the cooling and heating capabilities and effects, the doors and windows of the house need to be closed. Over time, due to the fact that the air conditioner's own system is an internal circulation system, the carbon dioxide in the room gradually increases, the oxygen gradually decreases, and the indoor air quality drops severely. Moreover, buying a new air purifier incurs certain costs. Therefore, it is very important to install a fresh air function inside the air conditioner. However, due to the indoor-outdoor temperature difference, the fresh air discharged makes people feel too cold or too hot, reducing the comfort level.

[0054] In view of this, the present invention proposes an air intake module and an air conditioner including the air intake module, wherein, Figures 1 to 7 is a schematic structural diagram of an embodiment of the air intake module provided by the present invention, Figures 8 to 10 is a schematic structural diagram of an embodiment of an air conditioner including the air intake module.

[0055] Please refer to Figure 1 and Figure 2 , the air intake module 100 includes a fresh air module 1 and an induced air module 5. The fresh air module 1 is formed with a fresh air inlet 11, a fresh air outlet 12, and a fresh air duct 13 connecting the fresh air inlet 11 and the fresh air outlet 12. The fresh air inlet 11 is used to communicate with the outside, and the fresh air outlet 12 is used to communicate with the inside. The induced air module 5 is formed with an induced air duct 53 and an induced air inlet 51 and an induced air outlet 52 connecting the induced air duct 53. The induced air inlet 51 is used to communicate with the inside, and the induced air outlet 52 is arranged at the air outlet end of the fresh air duct 13. Under the guiding action of the fresh air flow in the fresh air duct 13, an induced air flow is formed in the induced air duct 53. After the induced air flow and the fresh air flow merge, they are blown out from the fresh air outlet 12.

[0056] In the technical solution provided by the present invention, the fresh air module 1 is formed with a fresh air inlet 11, a fresh air outlet 12, and a fresh air duct 13 connecting the fresh air inlet 11 and the fresh air outlet 12. The fresh air module 1 is used to introduce the outside air into the room and form a fresh air flow in the fresh air duct 13. The induced air module 5 is formed with an induced air duct 53 and an induced air inlet 51 and an induced air outlet 52 connecting the induced air duct 53. The induced air inlet 51 is used to communicate with the inside, and the induced air outlet 52 is arranged at the air outlet end of the fresh air duct 13. Under the guiding action of the fresh air flow in the fresh air duct 13, an induced air flow is formed in the induced air duct 53. After the induced air flow and the fresh air flow merge, they are blown out from the fresh air outlet 12, reducing the temperature difference between the air blown out by the air intake module 100 and the indoor air, improving the user's comfort level, and further enhancing the user experience.

[0057] It should be noted that the induced air outlet 52 is arranged at the air outlet end of the fresh air duct 13 so that the induced air flow converges with the air flow in the fresh air duct 13. In this embodiment, the negative pressure in the fresh air duct 13 sucks the indoor air from the induced air inlet 51 into the fresh air duct 13 without the need to additionally increase power, reducing the structural arrangement.

[0058] In the present invention, the specific position of the induced air inlet 51 arranged in the fresh air duct 13 is not limited. Considering the embodiment where the power of the fresh air module 1 is a centrifugal air wheel, the fresh air module 1 includes a fresh air volute 14. The fresh air duct 13 is defined within the fresh air volute 14. A fresh air centrifugal air wheel 15 is arranged in the fresh air duct 13. The induced air inlet 51 is arranged on the circumferential side of the fresh air volute 14. The fresh air centrifugal air wheel 15 rotates to form a fresh air flow in the circumferential direction of the fresh air volute 14, and a negative pressure area is also formed in the circumferential direction of the fresh air volute 14. At this time, arranging the induced air outlet 52 on the circumferential side of the fresh air volute 14 facilitates the rapid induction of indoor air into the fresh air duct 13.

[0059] In one embodiment, the direction of the induced air inlet 51 towards the induced air outlet 52 is the extending direction of the induced air duct 53. The induced air outlet 52 is arranged adjacent to the fresh air outlet 12, and the induced air inlet 51 is arranged away from the fresh air outlet 12 so that the extending direction of the induced air duct 53 is towards the fresh air outlet 12. The extending direction of the induced air duct 53 is set to be as parallel as possible to the tangential direction of the induced air outlet 52 on the fresh air volute 14. At this time, on the one hand, the risk of the air flow in the fresh air duct 13 escaping from the induced air outlet 52 is reduced; on the other hand, the gas flow rate at the induced air outlet 52 is greater than the gas flow rate at the fresh air outlet 12, facilitating the rapid inhalation of indoor air into the fresh air duct 13 for mixing.

[0060] Furthermore, in one embodiment, along the extending direction of the induced air duct 53, the induced air duct 53 is tapered. At this time, the air flow rate at the induced air outlet 52 is relatively large, facilitating the rapid inhalation of indoor air into the fresh air duct 13 for mixing.

[0061] To increase the air volume of indoor air mixing, it is necessary to increase the ventilation area of the induced air inlet 51. In one embodiment, please refer to Figure 2, the induced air inlet 51 has an air inlet width along the axial direction of the fresh air volute 14, the air inlet width is L, and 10mm ≤ L ≤ 30mm. With such a setting, the induced air inlet 51 has a relatively large ventilation area, enabling more indoor air to mix with the fresh air in the fresh air duct 13. Preferably, 15mm ≤ L ≤ 25mm.

[0062] Please refer to Figure 2 and Figure 3 , in another embodiment of the air guiding module 100 provided by the present invention, the air guiding module 100 further includes a mixing air module 2. A mixing air duct 23 is formed in the mixing air module 2, and a mixing air inlet 21 and a mixing air outlet 22 communicating with the mixing air duct 23 are provided. Both the mixing air inlet 21 and the mixing air outlet 22 are used to communicate with the indoor space. The mixing air outlet 22 is adjacent to and arranged on the same side as the fresh air outlet 12, so that the mixing air flow converges with the air flow blown out from the fresh air outlet 12. Through the supplementary mixing air of the mixing air module 2, more indoor air is combined with the fresh air, further quickly reducing the temperature difference between the fresh air and the indoor air, improving the user comfort, and thus enhancing the user experience.

[0063] In one embodiment, please refer to Figures 4 to 7 , the mixing air module 2 includes a mixing air volute 24 and a mixing air centrifugal impeller 25 disposed in the mixing air volute 24. The mixing air duct 23 is defined in the mixing air volute 24. The mixing air inlet 21 is provided at one end of the mixing air volute 24, and the mixing air outlet 22 is provided on the circumferential side of the mixing air volute 24. The fresh air module 1 includes a fresh air volute 14 and a fresh air centrifugal impeller 15 disposed in the fresh air volute 14. The fresh air volute 14 is disposed at the other end of the mixing air volute 24. The fresh air duct 13 is defined in the fresh air volute 14. The fresh air inlet 11 is provided at the side end of the fresh air volute 14 facing away from the mixing air outlet 22, and the fresh air outlet 12 is provided on the circumferential side of the fresh air volute 14. By providing centrifugal impellers and forming gas flow channels in the corresponding volutes, the fresh air outlet 12 and the mixing air outlet 22 can be arranged on the circumferential sides of the corresponding volutes at this time, facilitating the layout of the fresh air outlet 12 and the mixing air outlet 22.

[0064] The present invention does not limit the driving methods of the mixing air centrifugal impeller 25 and the fresh air centrifugal impeller 15. They can be independently driven by motors respectively, or coaxially arranged and driven by one motor. In one embodiment, the mixing air centrifugal impeller 25 and the fresh air centrifugal impeller 15 are coaxially connected and arranged. With such a setting, the structure is compact, facilitating the miniaturization of the air guiding module 100.

[0065] In one embodiment, please refer in detail to Figure 5 andFigure 7 The air induction module 100 further includes a driving motor 3. The driving motor 3 includes an inner stator assembly 31 and two outer rotor assemblies 32. Both ends of the inner stator assembly 31 are respectively arranged in the air mixing air duct 23 and the fresh air duct 13. The two outer rotor assemblies 32 are rotatably sleeved on the inner stator assembly 31 at intervals and are respectively located in the air mixing air duct 23 and the fresh air duct 13. Among them, the air mixing centrifugal impeller 25 and the fresh air centrifugal impeller 15 are respectively arranged on the two outer rotor assemblies 32. By adopting the form of an outer rotor motor and placing the stator inside, the overall structure is compact. In addition, by using the two outer rotor assemblies 32, one motor can be used to conveniently drive the rotation of the two impellers, saving space.

[0066] Please continue to refer to Figure 5 and Figure 7 In one embodiment, the air induction module 100 further includes a purification component 4. The purification component 4 is arranged in the fresh air duct 13. Before the fresh air introduced from the outside enters the room, it needs to be filtered so that the introduced fresh air has better cleanliness. In one embodiment, the filtering component includes a filter net 41, which has a simple structure and is convenient to install.

[0067] The purification component 4 can be at any position in the fresh air flow path before the fresh air outlet 12. In one embodiment, a fresh air centrifugal impeller 15 is rotatably installed in the fresh air duct 13. The purification component 4 is arranged between the fresh air centrifugal impeller 15 and the fresh air inlet 11. An installation space can be directly set in the fresh air volute 14 to install the purification component 4, which is convenient for the setting of the purification component 4.

[0068] Please refer to FIGS. 8 to Figure 10 The present invention further provides an air conditioner 1000. The air conditioner 1000 includes a housing 200 and an air induction module 100 arranged in the housing 200. Since the air conditioner 1000 adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated herein one by one. The air conditioner 1000 is any one of a wall-mounted air conditioner indoor unit, a cabinet-type air conditioner indoor unit, an air machine, a ceiling-mounted air conditioner indoor unit, and a mobile air conditioner 1000. Hereinafter, the air conditioner 1000 is taken as an example of a wall-mounted air conditioner indoor unit for introduction and description.

[0069] In one embodiment, the housing 200 is provided with a first air inlet 207, a second air inlet 203, a first air outlet 201 and a second air outlet 202. Among them, the first air inlet 207 and the first air outlet 201 are in communication. The air guiding module 100 is arranged inside the housing 200. The induced air inlet 51 is adapted to communicate with the second air inlet 203. The fresh air outlet 12 of the air guiding module 100 is adapted to communicate with the second air outlet 202. The fresh air inlet 11 is adapted to communicate with the outdoor environment through a fresh air pipe. Thus, the air conditioner 1000 has an indoor air circulation mode and a fresh air mode, wherein:

[0070] In the indoor air circulation mode, the air in the indoor environment enters the interior of the housing 200 through the first air inlet 207, forms cold air or hot air after heat exchange by the heat exchange component inside the housing 200, and then blows back into the indoor environment from the first air outlet 201, realizing the indoor air circulation.

[0071] In the fresh air mode, the air in the outdoor environment enters the fresh air module 1 through the fresh air pipe, forms clean fresh air after being purified by the purification component 4 of the fresh air module 1. The air in the indoor environment mixes with the fresh air from the second air inlet 203 through the induced air module 5, and then passes through the second air outlet 202 of the housing 200 and blows into the indoor environment from the second air outlet 202, realizing the replenishment of fresh air to the indoor environment.

[0072] It should be noted that the first air inlet 207 and the second air inlet 203 can be set as one air inlet or can be set independently.

[0073] In one embodiment, the air guiding module 100 further includes a mixing air module 2. A mixing air duct 23 is formed inside the mixing air module 2, and a mixing air inlet 21 and a mixing air outlet 22 communicating with the mixing air duct 23 are provided. Both the mixing air inlet 21 and the mixing air outlet 22 are used to communicate with the interior of the room. The mixing air outlet 22 is adjacent to and arranged on the same side as the fresh air outlet 12, so that the mixing air flow converges with the air flow blown out from the fresh air outlet 12. The mixing air outlet 22 is adapted to communicate with the second air outlet 202. The mixing air inlet 21 is arranged inside the housing 200. With such a setting, it is convenient for the mixed air at the mixing air outlet 22 to be blown out from inside the housing 200.

[0074] The air mixing air inlet 21 formed on the air mixing volute 24 is arranged inside the housing 200 to form an open air inlet. In one embodiment, the air conditioner 1000 further includes an indoor heat exchanger 300 disposed inside the housing 200. The indoor heat exchanger 300 is located between the first air inlet 207 and the first air outlet 201. The air mixing air inlet 21 is disposed adjacent to the indoor heat exchanger 300. At this time, the temperature of the air at the air mixing air outlet 22 is higher or lower than the room temperature. By mixing with the lower or higher fresh air introduced from the outside, the mixed air flow is closer to the room temperature, improving the user's comfort.

[0075] In one embodiment, the air conditioner 1000 is a wall-mounted air conditioner indoor unit. The housing 200 of the air conditioner 1000 includes a chassis 204, a front frame 205 and a panel 206. The air guiding module 100 is installed at the end of the chassis 204. The fresh air outlet 12 of the air guiding module 100 is open to the panel 206. The panel 206 is provided with the second air outlet 202 at a position corresponding to the fresh air outlet 12, so that the air conditioner 1000 sends fresh air forward, enabling the fresh air to accurately reach the position where the user is located.

[0076] In addition, to prevent the fresh air from directly blowing on the user, the second air outlet 202 may optionally be composed of a plurality of micropores penetrating through the panel 206. After the fresh air blows out from the plurality of micropores, the air flow is broken up into strands of smaller filamentous air flows, the wind speed is reduced, and the air flow becomes gentle, not directly blowing on the user and avoiding discomfort for the user.

[0077] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
