Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a fresh air module and an air conditioner. Background Technology

[0002] Currently, the fresh air modules in air conditioners on the market have limited functionality, only able to introduce outdoor air into the room in fresh air mode, resulting in a poor user experience. Summary of the Invention

[0003] The problem solved by this invention is that the fresh air module has limited functionality and a poor user experience.

[0004] To address the aforementioned issues, this invention provides a fresh air module that simultaneously possesses fresh air, purification, and sewage discharge functions, significantly enhancing the user experience.

[0005] An embodiment of the present invention provides a technical solution:

[0006] A fresh air module includes a housing, a fan, a purification filter, and a fresh air filter. The housing has an air inlet chamber and a fan chamber. The housing has a fresh air inlet, a purification air inlet, and a waste air inlet. The fan is installed in the fan chamber.

[0007] Both the fresh air filter and the purification filter are installed in the air inlet cavity, which is divided into a fresh air inlet cavity, a purification air inlet cavity, and a waste air inlet cavity. The purification air inlet cavity is located on the air inlet side of the purification filter, the fresh air inlet cavity is located on the air outlet side of the purification filter, the waste air inlet cavity is located on the air outlet side of the fresh air filter, the waste air inlet cavity is located on the air outlet side of the fresh air filter, the waste air inlet cavity is connected to the fan cavity, the fresh air outlet is connected to the fresh air inlet cavity, the purification air inlet is connected to the purification air inlet cavity, and the waste air inlet is connected to the waste air inlet cavity.

[0008] The fresh air module provided in this invention can operate in fresh air mode, purification mode, and sewage discharge mode respectively in practical applications. In fresh air mode, the fan operates, drawing outdoor air into the fresh air intake chamber through the fresh air inlet. After being filtered and purified by the fresh air filter, the air enters the waste air intake chamber, and finally enters the fan chamber from the waste air intake chamber, and is discharged into the room through the indoor air outlet. In purification mode, the fan operates, drawing indoor air into the purification intake chamber through the purification inlet. After being filtered and purified by the purification filter, the air enters the fresh air intake chamber, and is then filtered and purified again by the fresh air filter before entering the waste air intake chamber. Finally, the waste air is drawn into the fan chamber from the waste air intake chamber and discharged into the room through the indoor air outlet, thus purifying the indoor air. In sewage discharge mode, the fan operates, drawing indoor air into the waste air intake chamber through the waste air inlet, and then into the fan chamber from the waste air intake chamber, before exhausting it outdoors, thus removing sewage from the indoor air. Therefore, the fresh air module provided in this embodiment of the invention has the functions of introducing outdoor fresh air, purifying indoor air, and exhausting indoor air, resulting in a better user experience.

[0009] In an optional embodiment, a first support plate and a second support plate are provided on the side wall of the housing away from the fan cavity. The first support plate and the second support plate both extend in the horizontal direction and are spaced apart in the vertical direction. The two ends of the purification filter in the vertical direction are respectively connected to the first support plate and the second support plate. The purification filter, the side wall of the housing away from the fan cavity, the first support plate and the second support plate together form the purification air inlet cavity.

[0010] In an optional embodiment, the first support plate is provided with a first guide slide on the side near the second support plate, and the second support plate is provided with a second guide slide on the side near the first support plate. The two ends of the purification filter in the vertical direction are respectively slidably engaged with the first guide slide and the second guide slide to be pulled out or inserted into the housing under the action of external force.

[0011] The purification filter slides into or out of the housing via the first and second guide slides, making it easy and quick to install and remove, and easy to clean and replace.

[0012] In an optional embodiment, the purification air inlet is located on the side wall of the housing away from the fan cavity, corresponding to the position between the first support plate and the second support plate. The purification air inlet is provided with a sliding baffle, which is used to open or close the purification air inlet under the action of external force.

[0013] The purification air inlet is located on the side wall of the casing away from the fan cavity, and it faces the air inlet end of the fan cavity, shortening the air intake path in the room and increasing the purification air volume. Furthermore, the side air intake avoids the influence of return air from the heat exchange return air vent at the top of the indoor unit, enhancing purification capacity.

[0014] In an optional embodiment, in the vertical direction, the first support plate is spaced apart from the top wall of the housing, and both the first support plate and the top wall of the housing serve as partial sidewalls defining the sewage air inlet cavity.

[0015] In an optional embodiment, the waste air inlet is located on the side wall of the housing away from the fan cavity, corresponding to the position between the first support plate and the top wall of the housing. The waste air inlet is provided with a sliding baffle, which is used to open or close the waste air inlet under the action of external force.

[0016] The sludge inlet is located on the side wall of the housing away from the fan cavity, between the first support plate and the top wall of the housing, so as to achieve side intake of sludge and avoid the sludge volume being reduced by the heat exchange return air inlet set on the top of the air conditioner.

[0017] In an optional embodiment, a first baffle is provided on the top wall of the housing, and a second baffle is provided on the bottom wall of the housing. The first baffle and the second baffle together divide the interior of the housing into the air inlet chamber and the fan chamber. A third support plate extending in the horizontal direction is protruding from the side of the second baffle away from the fan chamber in the horizontal direction. The third support plate is located on the side of the second support plate away from the first support plate in the vertical direction. The two ends of the fresh air filter in the vertical direction are respectively connected to the first support plate and the third support plate.

[0018] A fresh air filter is installed between the purification filter and the fan cavity. The purification filter and the fresh air filter face the fan cavity. The indoor air that has been filtered and purified by the purification filter can be further purified at the fresh air filter. It reaches the polluted air inlet cavity and the fan cavity with the shortest path, improving the purification air volume and efficiency.

[0019] In an optional embodiment, the first support plate is provided with a third guide slide on the side of the third support plate in the vertical direction, and the third support plate is provided with a fourth guide slide on the side of the first support plate in the vertical direction. The two ends of the fresh air filter in the vertical direction are respectively slidably engaged with the third guide slide and the fourth guide slide to be pulled out or inserted into the housing under the action of external force.

[0020] The fresh air filter slides into or out of the housing via the third and fourth guide sections, making it easy and quick to install and remove, and easy to clean and replace.

[0021] In an optional implementation, from the end connected to the third support plate to the end connected to the first support plate, the fresh air filter gradually moves away from the vertical plane where the first baffle and the second baffle are located.

[0022] The fresh air filter, together with the first and second baffles, forms a gradually narrowing flow channel, which can reduce the resistance of the sludge air intake.

[0023] In an optional embodiment, an air inlet for the fan chamber is formed between the first baffle and the second baffle, and the vertical projection of the fresh air filter on the plane where the first baffle and the second baffle are located covers at least 80% of the area of ​​the air inlet.

[0024] The vertical projection of the fresh air filter in the horizontal direction covers at least 80% of the air inlet of the fan cavity, further increasing the fresh air intake.

[0025] In an optional embodiment, the fresh air module further includes an air outlet switching component disposed on the housing. The fan cavity is provided with an air inlet and an air outlet. The air inlet is connected to the stale air inlet cavity. The housing is also provided with an indoor air outlet and an outdoor air exhaust outlet. The air outlet switching component is used to connect the air outlet to one of the indoor air outlet and the outdoor air exhaust outlet, and to block the connection between the fresh air inlet and the fresh air inlet cavity when the air outlet is connected to the outdoor air exhaust outlet.

[0026] In fresh air mode, the air outlet switching component connects the fresh air inlet to the fresh air intake chamber and the indoor air outlet to the air outlet, thereby drawing in fresh outdoor air and expelling it into the room. In purification mode, the air outlet switching component blocks the connection between the fresh air inlet and the fresh air intake chamber and connects the indoor air outlet to the air outlet, thereby purifying the drawn-in indoor air before expelling it into the room. In wastewater discharge mode, the air outlet switching component blocks the connection between the fresh air inlet and the fresh air intake chamber and connects the air outlet to the outdoor exhaust vent, thereby expelling the drawn-in indoor air to the outside through the outdoor exhaust vent.

[0027] In an optional embodiment, the purified air inlet and / or the polluted air inlet are located on the side wall of the housing away from the fan cavity.

[0028] The purification air inlet and the waste air inlet are located on the side wall of the casing to achieve lateral air intake, thereby keeping them away from the heat exchange return air inlet at the top of the indoor unit and preventing the air intake of the heat exchange return air inlet from affecting the air intake of the purification air inlet and the waste air inlet.

[0029] An embodiment of the present invention also provides an air conditioner, including the aforementioned fresh air module. The fresh air module includes a housing, a fan, a purification filter, and a fresh air filter. The housing is provided with an air inlet chamber and a fan chamber. The housing is provided with a fresh air inlet, a purification air inlet, and a waste air inlet. The fan is installed in the fan chamber. The fresh air filter and the purification filter are both installed in the air inlet chamber, dividing the air inlet chamber into a fresh air inlet chamber, a purification air inlet chamber, and a waste air inlet chamber. The purification air inlet chamber is connected to the fresh air inlet chamber through the purification filter. The fresh air inlet chamber is connected to the waste air inlet chamber through the fresh air filter. The waste air inlet chamber is connected to the fan chamber. The fresh air inlet is connected to the fresh air inlet chamber. The purification air inlet is connected to the purification air inlet chamber. The waste air inlet is connected to the waste air inlet chamber.

[0030] The air conditioner provided in this embodiment of the invention can operate in three modes: fresh air mode, purification mode, and exhaust mode. In fresh air mode, the fan operates, drawing outdoor air into the fresh air intake chamber through the fresh air inlet. After being filtered and purified by the fresh air filter, the air enters the waste air intake chamber, and finally enters the fan chamber from the waste air intake chamber, and is then exhausted into the room through the indoor air outlet. In purification mode, the fan operates, drawing indoor air into the purification intake chamber through the purification inlet. After being filtered and purified by both the purification filter and the fresh air filter, the air enters the waste air intake chamber, and is finally drawn into the fan chamber from the waste air intake chamber, and then exhausted into the room through the indoor air outlet, thus purifying the indoor air. In exhaust mode, the fan operates, drawing indoor air into the waste air intake chamber through the waste air inlet, and then into the fan chamber from the waste air intake chamber, before exhausting it to the outside through the fresh air outlet, thus removing waste from the indoor air. Therefore, the fresh air module provided in this embodiment of the invention simultaneously possesses the functions of introducing outdoor fresh air, purifying indoor air, and exhausting indoor air, resulting in a better user experience.

Detailed Implementation

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Please see Figure 1 , Figure 1 The image shown is a cross-sectional view of the fresh air module 100 provided in this embodiment in fresh air mode.

[0042] The fresh air module 100 provided in this embodiment is applied to an air conditioner 200. The fresh air module 100 includes a housing 110, a fan 130, a purification filter 150, a fresh air filter 170, and an air outlet switching assembly 180. The housing 110 has an air inlet chamber and a fan chamber 111. The housing 110 has a purification air inlet 113, a fresh air inlet 112, a waste air inlet 114, an indoor air outlet 120, and an outdoor air outlet 124. The fan 130 is installed in the fan chamber 111.

[0043] The fan cavity 111 is provided with an air inlet 1111 and an air outlet 1112. The air inlet 1111 is connected to the air inlet cavity. The air outlet switching component 180 is provided on the housing 110 and is used to selectively connect the fresh air inlet 112 to the air inlet cavity, and to connect the air outlet 1112 of the fan cavity 111 to the outdoor exhaust vent 124 or the indoor exhaust vent 120. It is also used to block the connection between the fresh air inlet 112 and the air inlet cavity when the air outlet 1112 is connected to the outdoor exhaust vent 124.

[0044] Both the purification filter 150 and the fresh air filter 170 are installed in the air inlet cavity, which divides the air inlet cavity into a purification air inlet cavity 122, a fresh air inlet cavity 121, and a waste air inlet cavity 123. The purification air inlet cavity 122 is connected to the fresh air inlet cavity 121 through the purification filter 150. The fresh air inlet cavity 121 is connected to the waste air inlet cavity 123 through the fresh air filter 170. The waste air inlet cavity 123 is connected to the fan cavity 111. The purification air inlet 113 is connected to the purification air inlet cavity 122. The fresh air inlet 112 is connected to the fresh air inlet cavity 121. The waste air inlet 114 is connected to the waste air inlet cavity 123.

[0045] In practical applications, when the air conditioner 200 operates in fresh air mode, the purified air inlet 113 and the polluted air inlet 114 are closed. The air outlet switching component 180 connects the fresh air inlet 112 with the fresh air intake chamber 121 and connects the air outlet 1112 of the fan chamber 111 with the indoor air outlet 120. In this state, the fan 130 rotates, drawing outdoor fresh air into the fresh air intake chamber 121 through the fresh air inlet 112. The outdoor fresh air entering the fresh air intake chamber 121 is filtered and purified by the fresh air filter 170 before flowing into the polluted air intake chamber 123. Then, it flows into the fan chamber 111 from the air inlet 1111 and out of the fan chamber 111 from the air outlet 1112, and into the room through the indoor air outlet 120, thus completing the introduction of outdoor fresh air.

[0046] Please refer to the following: Figure 2 , Figure 2 The image shown is a cross-sectional view of the fresh air module 100 provided in this embodiment in purification mode.

[0047] When the air conditioner 200 operates in purification mode, the polluted air inlet 114 is closed, the purified air inlet 113 is opened, and the air outlet switching component 180 blocks the connection between the fresh air inlet 112 and the fresh air inlet cavity 121, while connecting the air outlet 1112 of the fan cavity 111 to the indoor air outlet 120. In this state, the fan 130 rotates, drawing indoor air into the purified air inlet cavity 122 through the purified air inlet 113. After entering the purified air inlet cavity 122, the indoor air is filtered and purified by the purification filter 150 before flowing into the fresh air inlet cavity 121. After being filtered and purified by the fresh air filter 170, it flows into the polluted air inlet cavity 123, then into the fan cavity 111 through the air inlet 1111, and finally out of the fan cavity 111 through the air outlet 1112, and into the room through the indoor air outlet 120, thus completing the purification of the indoor air.

[0048] Please refer to the following: Figure 3 , Figure 3 The image shown is a cross-sectional view of the fresh air module 100 provided in this embodiment in the sewage discharge mode.

[0049] When the air conditioner 200 operates in the sewage discharge mode, the purified air inlet 113 is closed, the polluted air inlet 114 is opened, and the air outlet switching component 180 blocks the connection between the fresh air inlet 112 and the fresh air intake chamber 121, and connects the air outlet 1112 of the fan chamber 111 to the outdoor exhaust vent 124. In this state, the fan 130 rotates, drawing indoor air into the polluted air intake chamber 123 through the polluted air inlet 114, and then into the fan chamber 111 through the air inlet 1111, and finally out through the outdoor exhaust vent 124 to the outside, thus achieving the discharge of polluted indoor air.

[0050] As can be seen, the fresh air module 100 provided in this embodiment has fresh air function, purification function and sewage discharge function, which can meet multiple functional requirements and provide a better user experience.

[0051] In this embodiment, the purification filter 150 is located on the horizontal left side of the fresh air filter 170, and the air inlet 1111 of the fan cavity 111 is located on the horizontal right side of the fresh air filter 170. The left side wall of the purification filter 150 is part of the side wall that forms the purification air inlet cavity 122. The right side wall of the purification filter 150 and the left side wall of the fresh air filter 170 are both part of the side walls that form the fresh air inlet cavity 121. The right side wall of the fresh air filter 170 is part of the side wall that forms the waste air inlet cavity 123.

[0052] Therefore, in practical applications, when the fresh air module 100 operates in fresh air mode, the outdoor fresh air entering the fresh air intake cavity 121 flows directly into the polluted air intake cavity 123 via the fresh air filter 170 without passing through the purification filter 150. This is to avoid the outdoor fresh air contaminating the purification filter 150, considering that the outdoor fresh air has a high content of dust particles and is heavily polluted. When the fresh air module 100 operates in purification mode, the indoor air entering the purification intake cavity 122 undergoes dual purification via both the purification filter 150 and the fresh air filter 170, significantly improving the indoor air purification effect.

[0053] In fact, the plane where the purification filter 150 is located is perpendicular to the horizontal plane, and the angle between the plane where the fresh air filter 170 is located and the horizontal plane is greater than 0° and less than 90°. Furthermore, the vertical projection of the purification filter 150 in the horizontal direction falls entirely within the range of the fresh air filter 170, which further increases the air volume and purification area of ​​the indoor air, shortens the travel distance of the indoor air, and improves the purification effect and efficiency.

[0054] As can be seen, in this embodiment, the vertical arrangement of the purification filter 150 and the inclined arrangement of the fresh air filter 170 improve the space utilization of the air inlet cavity of the housing 110. Furthermore, the presence of a portion of the fresh air inlet cavity 121 between the purification filter 150 and the fresh air filter 170 prevents the purification filter 150 from obstructing the fresh air intake, ensuring smooth fresh air intake.

[0055] In this embodiment, the side wall of the housing 110 away from the fan cavity 111 is the left wall of the housing, and a first support plate 115 and a second support plate 116 are provided on the left wall of the housing. The first support plate 115 and the second support plate 116 both extend in the horizontal direction and are spaced apart in the vertical direction. The purification filter 150 is connected to the first support plate 115 and the second support plate 116 at both ends in the vertical direction, and the purification filter 150, the left wall of the housing 110, the first support plate 115 and the second support plate 116 together form the purification air inlet cavity 122.

[0056] The first support plate 115 is provided with a first guide slide 1151 on the side near the second support plate 116, and the second support plate 116 is provided with a second guide slide 1161 on the side near the first support plate 115. The two ends of the purification filter 150 in the vertical direction are respectively slidably engaged with the first guide slide 1151 and the second guide slide 1161, so as to be pulled out or inserted into the housing 110 under the action of external force.

[0057] Considering that in practical applications, the purification filter 150 needs to be cleaned or replaced periodically, requiring disassembly and reassembly, in order to facilitate the disassembly and reassembly of the purification filter 150 on the housing 110, in this embodiment, a first guide slide 1151 is provided on the side of the first support plate 115 near the second support plate 116, and a second guide slide 1161 is provided on the side of the second support plate 116 near the first support plate 115. The purification filter 150 slides in cooperation with the first guide slide 1151 and the second guide slide 1161. Under the action of external force, the purification filter 150 can slide out of the housing 110 along the first guide slide 1151 and the second guide slide 1161 to clean or replace the purification filter 150, and can slide back into the housing 110 along the first guide slide 1151 and the second guide slide 1161 to achieve quick installation of the purification filter 150.

[0058] In this embodiment, the purification air inlet 113 is located on the left side wall of the housing 110, corresponding to the position between the first support plate 115 and the second support plate 116. The purification air inlet 113 is located on the left side plate of the housing 110, meaning that it is directly opposite the air inlet 1111 of the purification filter 150, the fresh air filter 170, and the fan chamber 111 in the horizontal direction, further shortening the airflow path within the purification room and increasing the purification air volume.

[0059] Furthermore, the first support plate 115 is spaced apart from the top wall of the housing 110. Both the first support plate 115 and the top wall of the housing 110 serve as part of the side wall defining the sewage air inlet cavity 123. The sewage air inlet 114 is opened on the left side wall of the housing 110 at a position corresponding to the position between the first support plate 115 and the top wall of the housing 110.

[0060] The waste air inlet 114 is located on the left side wall of the housing 110, which can prevent the air intake of the waste air inlet 114 from being interfered with by the air intake of the air conditioner return air vent, thus ensuring the air intake volume of the waste air inlet 114.

[0061] In this embodiment, a sliding baffle 117 is slidably provided on the left side plate of the housing 110. The sliding baffle 117 is used to slide relative to the housing 110 in the vertical direction under the action of external force to open one of the purification air inlet 113 and the sewage air inlet 114, or to close the purification air inlet 113 and the sewage air inlet 114 at the same time.

[0062] The purified air inlet 113 is positioned below the polluted air inlet 114. In fresh air mode, the sliding baffle 117 simultaneously closes both the purified air inlet 113 and the polluted air inlet 114. In purification mode, the sliding baffle 117 slides upward to open the purified air inlet 113 while keeping the polluted air inlet 114 closed. In exhaust mode, the sliding baffle 117 slides downward to open the polluted air inlet 114 and close the purified air inlet 113.

[0063] In practical applications, the air conditioner 200 is equipped with a drive device to drive the sliding baffle 117 to slide up and down. This drive device responds to the control of the air conditioner 200, thereby controlling the sliding baffle 117 to move to different positions when the air conditioner 200 switches between different modes. It is understood that in other embodiments, the opening and closing control of the purified air inlet 113 and the waste air inlet 114 can also adopt other devices or structures. For example, two separate control valves can be used to achieve individual control of the purified air inlet 113 and the waste air inlet 114.

[0064] A first baffle 118 is provided on the inner side of the top wall of the housing 110, and a second baffle 119 is provided on the bottom wall of the housing 110. The first baffle 118 and the second baffle 119 together divide the interior of the housing 110 into an air inlet chamber and a fan chamber 111. That is, the first baffle 118 and the second baffle 119 are arranged opposite each other in the vertical direction. The horizontal left side of the first baffle 118 and the second baffle 119 and the inner wall of the housing 110 form the air inlet chamber, and the horizontal right side of the first baffle 118 and the second baffle 119 and the inner wall of the housing 110 form the fan chamber 111.

[0065] A third support plate 1191 extending horizontally is provided on the side of the second baffle 119 away from the fan cavity 111. The third support plate 1191 is located on the side of the second support plate 116 away from the first support plate 115 in the vertical direction. That is, in the vertical direction, the first support plate 115, the second support plate 116 and the third support plate 1191 are arranged in sequence at intervals. The two ends of the fresh air filter 170 in the vertical direction are connected to the first support plate 115 and the third support plate 1191 respectively.

[0066] The first support plate 115 has a third guide slide 1152 on the side of the third support plate 1191 in the vertical direction. The third support plate 1191 has a fourth guide slide 1192 on the side of the first support plate 115 in the vertical direction. The fresh air filter 170 has two ends in the vertical direction that slide in cooperation with the third guide slide 1152 and the fourth guide slide 1192 respectively, so as to be pulled out or inserted into the housing 110 under the action of external force.

[0067] Similarly, considering that the fresh air filter 170 needs to be cleaned or replaced regularly in practical applications, requiring disassembly and reassembly, in order to facilitate the disassembly and reassembly of the fresh air filter 170 on the housing 110, in this embodiment, a third guide slide 1152 is provided on the side of the first support plate 115 near the third support plate 1191, and a fourth guide slide 1192 is provided on the side of the fourth support plate near the first support plate 115. The fresh air filter 170 slides in cooperation with the third guide slide 1152 and the fourth guide slide 1192. Under the action of external force, the fresh air filter 170 can slide out of the housing 110 along the third guide slide 1152 and the fourth guide slide 1192 to clean or replace the fresh air filter 170, and can slide back into the housing 110 along the third guide slide 1152 and the fourth guide slide 1192 to achieve quick installation of the fresh air filter 170.

[0068] Furthermore, since the fresh air filter 170 is inclined in this embodiment, from the end connected to the third support plate 1191 to the end connected to the first support plate 115, the fresh air filter 170 gradually moves away from the vertical plane where the first baffle 118 and the second baffle 119 are located.

[0069] As can be seen, the fresh air filter 170, the first baffle 118 and the second baffle 119 form a flow channel that gradually narrows from top to bottom. This flow channel is part of the sewage air inlet cavity 123, and the internal wind resistance gradually decreases, thereby increasing the flow rate of the sewage air entering from above the fresh air filter 170.

[0070] An air inlet is formed between the first baffle 118 and the second baffle 119, which is the end face of the air inlet 1111 of the fan chamber 111 that connects to the waste air inlet chamber 123. In this embodiment, in order to increase the air volume of fresh air and purification, the vertical projection of the fresh air filter 170 in the horizontal direction covers at least 80% of the area of ​​the air inlet.

[0071] Please refer to the following: Figure 4 , Figure 5 and Figure 6 , Figure 4 The diagram shown is a structural schematic of the air outlet switching component 180. Figure 5 As shown Figure 5 This is a schematic diagram showing the connection structure between the air outlet switching component 180 and the housing 110 in fresh air mode or purification mode. Figure 6 This is a schematic diagram of the connection structure between the air outlet switching component 180 and the housing 110 in the sewage discharge mode.

[0072] The air outlet switching assembly 180 is provided with a first air guide cavity 181 and a second air guide cavity 182. The first air guide cavity 181 and the second air guide cavity 182 are connected inside the air outlet switching assembly 180. A first rotating baffle 183 is provided on the air outlet switching assembly 180 corresponding to the first air guide cavity 181. The first rotating baffle 183 can be rotated to a position that seals or opens the first air guide cavity 181. A second rotating baffle 184 is provided on the air outlet switching assembly 180 corresponding to the second air guide cavity 182. The second rotating baffle 184 can be rotated to a position that seals or opens the second air guide cavity 182. An opening for connecting to the outside is provided on the cavity wall of the second air guide cavity 182.

[0073] By configuring the position of the air outlet switching component 180 on the housing 110, the first air guide cavity 181 corresponds to the outdoor exhaust vent 124, and the second air guide cavity 182 corresponds to the fresh air vent 112. When the first rotating baffle 183 rotates to the position of opening the first air guide cavity 181, the first rotating baffle 183 covers the indoor air outlet 120, thereby connecting the air outlet 1112 of the fan cavity 111 with the first air guide cavity 181 through the outdoor exhaust vent 124; when the first rotating baffle 183 rotates to the position of covering the first air guide cavity 181, it connects the air outlet 1112 with the indoor air outlet 120. When the second rotating baffle 184 rotates to the position of sealing the second air guide cavity 182, it blocks the fresh air inlet 112 from the fresh air intake cavity 121; when the second rotating baffle 184 rotates to the position of opening the second air guide cavity 182, it connects the fresh air inlet 112 to the fresh air intake cavity 121.

[0074] Please refer to the following: Figures 1 to 6 In fresh air mode, the first rotating baffle 183 rotates to the position of covering the first air guide cavity 181, i.e., covering the outdoor exhaust vent 124, and the second rotating baffle 184 rotates to the position of opening the second air guide cavity 182. At this time, the air outlet 1112 of the fan cavity 111 is connected to the indoor air outlet 120, and the fresh air inlet 112 is connected to the fresh air inlet cavity 121. In purification mode, the first rotating baffle 183 rotates to the position of covering the first air guide cavity 181, and the second rotating baffle 184 rotates to the position of covering the second air guide cavity 182. At this time, the air outlet of the fan cavity 111... The air outlet 1112 is connected to the indoor air outlet 120, while the fresh air inlet 112 is not connected to the fresh air intake cavity 121. In the sewage discharge mode, the first rotating baffle 183 rotates to the position of opening the first air guide cavity 181, and the second rotating baffle 184 rotates to the position of sealing the second air guide cavity 182. At this time, the air outlet 1112 of the fan cavity 111 is connected to the first air guide cavity 181 through the outdoor exhaust vent 124, and the opening on the cavity wall of the second air guide cavity 182 is connected to the first air guide cavity 181 through the second air guide cavity 182. The fresh air outlet 211 is not connected to the fresh air inlet 112.

[0075] It is understood that in other embodiments, the structure of the air outlet switching component 180 may be adjusted or replaced according to actual application conditions.

[0076] In summary, the fresh air module 100 provided in this embodiment, in addition to its fresh air function, also has the functions of purifying indoor air and expelling polluted indoor air to the outside, making it applicable to a wider range of scenarios. In practical applications, it can quickly improve indoor air quality and provide a better user experience.

[0077] In addition, this embodiment also provides an air conditioner 200, please refer to [link / reference]. Figure 7 , Figure 7 The diagram shown is a structural schematic of the air conditioner 200.

[0078] The air conditioner 200 provided in this embodiment is equipped with the aforementioned fresh air module 100. In fact, the fresh air module 100 is located at one end of the casing 210 of the air conditioner 200, with the purified air inlet 113 and the waste air inlet 114 correspondingly located on the side wall of the casing 210. The purified filter 150 and the fresh air filter 170 are inserted through the side wall of the casing 210, allowing for quick installation and removal of the purified filter 150 and the fresh air filter 170 without disassembling the unit. The indoor air outlet 120 is located on one side of the air outlet 211 on the casing 210, allowing the purified exhaust air or fresh air exhaust to quickly mix with the exhaust air from the air outlet 211, improving user comfort.

[0079] In summary, the air conditioner 200 provided in this embodiment, in addition to its fresh air function, also has the functions of purifying indoor air and expelling polluted indoor air to the outside, making it applicable to a wider range of scenarios.
