Description

Technical Field

[0001] This application relates to the field of air duct reversing in fresh air systems, and more particularly to a reversing device and an air conditioner. Background Technology

[0002] In the design of ventilation systems in modern buildings, fresh air systems and recirculating air systems are two important components. Fresh air systems are primarily responsible for introducing fresh outdoor air into the room, purifying and filtering it to provide a healthy breathing environment for occupants. Recirculating air systems, on the other hand, primarily circulate indoor air, maintaining a comfortable indoor environment by regulating parameters such as temperature and humidity. To achieve the functions of these two systems, they typically employ independent return air duct structures. This structural design effectively avoids mutual interference between fresh air and recirculated air, ensuring smooth and stable airflow.

[0003] In traditional duct systems, since the positions of the two air inlets are fixed, if the air inlet duct and the recirculation duct are connected in reverse during duct installation, it is usually necessary to disassemble and reassemble the duct, and then connect the duct by winding the duct or installing additional connecting parts such as elbows and flexible hoses. This not only increases the complexity of construction, but also affects the overall aesthetics and duct efficiency. Utility Model Content

[0004] This application provides a reversing device and an air conditioner to solve the problem that, due to the fixed positions of the two air inlets, if the air inlet duct and the recirculation duct are connected in reverse during duct installation, it is usually necessary to disassemble and reassemble the duct, and then connect the duct by winding the duct or installing additional connecting components such as elbows and flexible hoses. This not only increases the complexity of construction, but also affects the overall aesthetics and duct efficiency.

[0005] In a first aspect, this application provides a commutation device applied to an air conditioner, comprising: A baffle bracket is provided with four ventilation openings, each of which is arranged in pairs on the baffle bracket. The baffle bracket is used to connect to the inner wall of the air conditioner. Two air vent baffles are movably mounted on the baffle bracket. Each of the two air vent baffles can block one of the air vents. The two blocked air vents are arranged diagonally.

[0006] Optionally, the orthographic projection of each of the air vent baffles in the first direction is greater than the orthographic projection of each of the ventilation openings in the first direction, and the periphery of each of the air vent baffles abuts against the periphery of a ventilation opening.

[0007] Optionally, each of the air vent baffles has a snap-fit ​​groove around its periphery, and the reversing device includes a seal located in the snap-fit ​​groove, the seal at least partially protruding from the snap-fit ​​groove.

[0008] Optionally, the two air vent baffles are slidably connected to the baffle bracket.

[0009] Optionally, the baffle bracket has a main body and mounting bends, the mounting bends being located at opposite ends of the main body, and the plane of each mounting bend being set at an angle to the plane of the main body.

[0010] Optionally, the baffle bracket has reinforcing portions at opposite ends, each of which extends along the length of the main body.

[0011] Secondly, this application provides an air conditioner, comprising: The housing has a first and a second flow channel that are isolated from each other, two air inlets and an air outlet. The two air inlets and the air outlet are located at opposite ends of the first and second flow channels, respectively. The first flow channel is used to connect fresh air and the second flow channel is used to connect recirculated air. The first fan is located in the first flow guide channel; The second fan is located in the second flow channel; The first aspect of this application provides a reversing device, which is located between the two air inlets and the first and second flow guide channels; Two of the ventilation openings are connected to the opening of the first flow channel, and the other two ventilation openings are connected to the opening of the second flow channel.

[0012] Optionally, a partition is provided between the two air inlets, the partition connecting the inner wall of the housing and the baffle bracket.

[0013] Optionally, the housing is provided with a mixing chamber, the mixing chamber is connected to the first flow channel and the second flow channel and the air outlet, and the air conditioner includes a heat exchanger, the heat exchanger is disposed in the mixing chamber.

[0014] Optionally, the mixing chamber is further provided with a fresh air filter and a circulating air filter, the fresh air filter being located at the outlet of the first guide channel and the circulating air filter being located at the outlet of the second guide channel.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: The reversing device provided in this embodiment enables rapid switching between the fresh air inlet and the recirculating air inlet by setting up a baffle bracket and a baffle plate. The baffle bracket is connected to the inner wall of the air conditioner by bolts or clips to ensure stable installation. The baffle bracket has four ventilation openings, arranged in pairs to form two sets of diagonal ventilation openings. Two air vent baffles are installed on the baffle bracket via a movable connection (such as a hinge or sliding connection), allowing each air vent baffle to move independently and block one set of diagonal ventilation openings. For example, if the fresh air duct and the recirculating air duct are reversed during installation, requiring a change in the airflow direction, the user can move the air vent baffle to open the previously blocked ventilation opening and simultaneously block the other set of diagonal ventilation openings, thus switching the airflow direction. By setting four ventilation openings and two movable air vent baffles, flexible switching of airflow direction can be achieved to meet the user's needs in different scenarios. This design improves the efficiency and comfort of the air conditioner and avoids the inconvenience of fixed airflow direction in traditional air conditioners. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0023] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0024] To address the technical problem in existing technologies where the fixed positions of the two air inlets 4c necessitate ductwork reassembly and reconnection if the air inlet and recirculation ducts are reversed during installation, necessitating the use of ductwork loops or additional connecting components such as elbows and flexible hoses, which increases construction complexity and negatively impacts aesthetics and duct efficiency, this application provides a reversing device. Users can manipulate the air vent baffle 2 to open the previously blocked vent 1a while simultaneously blocking the other diagonally opposite vent 1a, thus switching the airflow direction. This eliminates the need for ductwork reassembly or the use of loops or additional connecting components.

[0025] Figures 1 to 3 A reversing device provided in this application embodiment is applied to an air conditioner, including a baffle bracket 1 and two air vent baffles 2. The baffle bracket 1 has four ventilation openings 1a, and each ventilation opening 1a is arranged in pairs side by side on the baffle bracket 1. The baffle bracket 1 is used to connect to the inner wall of the air conditioner. The two air vent baffles 2 are movably arranged on the baffle bracket 1, and each of the two air vent baffles 2 can block one ventilation opening 1a. The two blocked ventilation openings 1a are arranged diagonally.

[0026] In this embodiment, the baffle bracket 1 is fixedly connected to the inner wall of the air conditioner by bolts or clips to ensure stable installation. The baffle bracket 1 has four ventilation openings 1a, arranged in pairs to form two sets of ventilation openings 1a. Two air vent baffles 2 are installed on the baffle bracket 1 via a movable connection (such as a hinge or sliding connection), allowing each air vent baffle 2 to move independently and block one set of diagonally opposite ventilation openings 1a. In actual use, if the user finds that the air inlet duct and the recirculation duct are connected in reverse, the user can manually move the air vent baffle 2 to open the previously blocked ventilation opening 1a while simultaneously blocking the other set of diagonally opposite ventilation openings 1a, thus switching the airflow direction quickly without needing to disassemble and reassemble the duct or install additional elbows, hoses, or other connecting components. This design is not only easy to operate but also adapts quickly to different installation situations, ensuring the normal operation of the air conditioner.

[0027] The reversing device provided in this application embodiment, by setting four ventilation openings 1a and two movable air vent baffles 2, can flexibly switch the airflow direction to meet the user's needs in different scenarios. This design avoids the trouble of disassembling and reinstalling the air ducts required by traditional duct systems due to the reverse connection of the air inlet and recirculation ducts. It also avoids the need for additional installation elbows or hoses during normal installation, reducing construction complexity and time costs. Secondly, the device can switch the airflow direction with a simple toggle operation, eliminating the need for additional elbows or hoses, thus improving the overall aesthetics and efficiency of the ductwork. In air conditioning installations in homes or commercial locations, users can quickly adjust the airflow direction of the fresh air and recirculation air according to actual needs without complex ductwork modifications. Furthermore, this design enhances the adaptability and flexibility of the air conditioner, reducing the hassle of reinstallation and adjustment due to installation errors or changes in requirements, and improving the user experience.

[0028] Please see Figure 1 In order to ensure that the air vent baffle 2 can completely block the air vent 1a, the orthographic projection of each air vent baffle 2 in the first direction is greater than the orthographic projection of each air vent 1a in the first direction, and the periphery of each air vent baffle 2 abuts against the periphery of an air vent 1a.

[0029] In one embodiment of this application, the size of the vent baffle 2 is designed to be slightly larger than the size of the vent 1a to ensure that it can completely cover the vent 1a in the blocked state, preventing air leakage. For example, if the size of the vent 1a is 30 cm × 10 cm, the size of the vent baffle 2 can be designed to be 32 cm × 11 cm. During installation, the vent baffle 2 is mounted on the baffle bracket 1 via hinges or sliding rails, allowing the baffle to move flexibly. When the vent baffle 2 is moved to the blocked position, its periphery tightly abuts against the periphery of the vent 1a, forming a good sealing effect. Specifically, in a residential air conditioning system, the user can manually move the vent baffle 2 to switch the direction of fresh air and recirculated air intake; in a central air conditioning system of a commercial building, the vent baffle 2 can be automatically switched by an automatic control device (such as a motor drive) to ensure accurate adjustment of the airflow direction.

[0030] This embodiment of the application significantly improves the sealing and efficiency of the ventilation system by ensuring that the air vent baffle 2 completely covers the air vent 1a. The orthographic projection of each air vent baffle 2 in a first direction is larger than the orthographic projection of each air vent 1a, and the periphery of the baffle tightly abuts against the periphery of the air vent 1a. This design effectively prevents air leakage, ensures the independence of fresh air and recirculated air, and avoids mutual interference between the two airflows. The first direction refers to the flow direction of the fresh air and recirculated air. For example, in medical facilities or laboratories where strict air quality control is required, this design ensures the purity of the fresh air and prevents pollutants in the recirculated air from mixing into the fresh air system. This design also improves the reliability and stability of the system, reduces energy waste caused by airflow leakage, and lowers operating costs.

[0031] Please see Figure 3 During long-term use, gaps may exist between the baffle bracket 1 and the air vent baffle 2. Each air vent baffle 2 has a snap-fit ​​groove 2a around its periphery. The reversing device includes a seal 3, which is located in the snap-fit ​​groove 2a and protrudes at least partially from the snap-fit ​​groove 2a.

[0032] In this embodiment, to address the potential gaps between the baffle bracket 1 and the vent baffle 2 during prolonged use, each vent baffle 2 has a snap-fit ​​groove 2a around its periphery, and a sealing element 3 is installed within the snap-fit ​​groove 2a. The sealing element 3 can be made of a flexible material (such as rubber or silicone) to ensure good elasticity. During installation, the sealing element 3 is placed within the snap-fit ​​groove 2a of the vent baffle 2, and at least partially protrudes from the snap-fit ​​groove 2a. When the vent baffle 2 moves to the blocking position, the sealing element 3 comes into close contact with the inner wall of the baffle bracket 1, forming a seal. For example, the sealing element 3 can be designed to protrude approximately 1-2 mm from the snap-fit ​​groove 2a to effectively fill any gaps that may occur upon contact. Specifically, in residential air conditioning systems, the sealing element 3 can be made of silicone, whose flexibility and elasticity can adapt to different installation environments; in industrial ventilation systems, the sealing element 3 can be made of high-temperature resistant rubber to meet the requirements of use in high-temperature environments.

[0033] This embodiment of the application significantly improves the sealing performance of the ventilation system by providing a snap-fit ​​groove 2a and a seal 3 around the periphery of the air outlet baffle 2. The elastic design of the seal 3 effectively fills any gaps that may appear between the baffle bracket 1 and the air outlet baffle 2, ensuring that air does not leak. This design not only improves the system's sealing performance and efficiency but also extends its service life and reduces energy waste caused by airflow leakage. For example, in a home environment, the seal 3 can effectively prevent unnecessary mixing of fresh air and recirculated air, which helps ensure the cleanliness of the air conditioner's internal components and the cleanliness of the airflow at the outlet 4d. This design also improves the system's reliability and stability and reduces maintenance costs. In a home air conditioning system, the use of silicone seal 3 can effectively prevent fresh air and recirculated air from mixing or entering an incompatible fan, thus preventing the air conditioner from affecting its performance.

[0034] Please see Figures 1 to 3 Since the air vent baffle 2 itself has a certain width, in order to minimize the size of the air inlet 4c and the size of the entire air conditioner, the two air vent baffles 2 are slidably connected to the baffle bracket 1.

[0035] In one embodiment, to minimize the size of the air inlet 4c and the overall size of the air conditioner, the two air vent baffles 2 are slidably connected to the baffle bracket 1. Specifically, the baffle bracket 1 is provided with a sliding track, and the air vent baffles 2 are connected to the baffle bracket 1 via the sliding track, allowing the air vent baffles 2 to slide freely on the track. This design allows the air vent baffles 2 to obscure two diagonally positioned ventilation chambers by sliding, thereby avoiding the large volume required for the air vent baffles 2 to rotate. This embodiment of the application, by adopting a sliding connection, significantly shortens the size of the air inlet 4c and the overall size of the air conditioner, improving the space utilization and aesthetics of the air conditioner. The sliding connection design allows the air vent baffles 2 to slide directly to the corresponding ventilation opening 1a position, reducing the protruding parts of the air conditioner and saving space. Furthermore, this design also improves the installation flexibility of the air conditioner, enabling it to adapt to more diverse installation environments.

[0036] Please see Figure 1 and Figure 2 Since the baffle bracket 1 is usually installed at an angle to the inner wall of the air conditioner, generally a right angle, in order to facilitate the installation of the baffle bracket 1, the baffle bracket 1 has a main body 11 and a mounting bending part 12. The mounting bending part 12 is located at opposite ends of the main body 11, and the plane of each mounting bending part 12 is set at an angle to the plane of the main body 11.

[0037] In this embodiment, the main body 11 is the main part of the baffle bracket 1, used to support the air vent baffle 2 and the vent 1a. Mounting bends 12 are located at opposite ends of the main body 11, and the plane of each mounting bend 12 is angled to the plane of the main body 11, typically a right angle. This design allows the baffle bracket 1 to better adapt to the structure of the air conditioner's inner wall. During installation, the mounting bends 12 can be connected to the inner wall of the air conditioner using bolts, clips, or other fixing devices. For example, if the air conditioner's interior is a rectangular structure, the mounting bends 12 can be perpendicular to the main body 11, forming an L-shaped structure, facilitating a tight fit with the horizontal or vertical mounting surface of the inner wall.

[0038] This embodiment of the application significantly improves the installation convenience and stability of the baffle bracket 1 by designing a main body 11 and an installation bending part 12. The installation bending part 12 is set at an angle to the main body 11, allowing the baffle bracket 1 to better adapt to the structure of the air conditioner's inner wall, ensuring the stability of the baffle bracket 1 whether installed vertically or horizontally. The angle between the installation bending part 12 and the main body 11 is determined according to the internal structure of the air conditioner, and is generally 90°; this design not only improves installation efficiency but also enhances system reliability. For example, in a conventional air conditioner, the design of the installation bending part 12 ensures that the main body 11 can be stably installed in the air conditioner to receive fresh air and recirculated air from the air inlet 4c, and then the duct switching between fresh air and recirculated air is achieved by the baffle 2 blocking the diagonally arranged vents 1a.

[0039] Please see Figure 1 and Figure 2 Since the baffle bracket 1 is generally a sheet metal part, its thickness has been reduced to a certain extent. Under the long-term action of fresh air and circulating air, the baffle bracket 1 is prone to deformation. The baffle bracket 1 also has reinforcing parts 13 at its opposite ends, and each reinforcing part 13 extends along the length direction of the main body 11.

[0040] In one embodiment, to enhance the structural strength of the baffle bracket 1 and prevent it from deforming due to the action of fresh and recirculated air during long-term use, reinforcing portions 13 are designed at opposite ends of the baffle bracket 1. These reinforcing portions 13 extend along the length of the main body 11, forming a longitudinally reinforced structure. Specifically, the baffle bracket 1 is typically made of sheet metal, and its main body 11 is relatively thin to reduce weight and cost. To improve structural strength, the reinforcing portions 13 can be connected to the main body 11 by bending or welding. For example, the reinforcing portions 13 can be designed as folded edges perpendicular to the main body 11, or the structure can be reinforced by welding additional metal strips. The reinforcing portions 13 can be designed as folded edges perpendicular to the main body 11, formed by a bending process, to enhance the longitudinal strength of the baffle bracket 1; simultaneously, the reinforcing portions 13 can be implemented by welding additional metal strips, which can be made of high-strength aluminum alloy to improve the overall structural stability.

[0041] This embodiment of the application significantly enhances the structural strength of the baffle bracket 1 by providing reinforcing portions 13 at opposite ends, effectively preventing deformation caused by the action of fresh and recirculated air during long-term use. The reinforcing portions 13 extend along the length of the main body 11, forming a longitudinally reinforced structure that improves the bending resistance and stability of the baffle bracket 1. This design not only extends the service life of the baffle bracket 1 but also improves the reliability and safety of the system. The baffle bracket 1, through the reinforcing portions 13, can better withstand the airflow impact during long-term use, reducing the risk of deformation and ensuring stability under high airflow and high-frequency operation.

[0042] Secondly, please refer to Figures 4 to 7 This application provides an air conditioner, including a housing 4, a first fan 41, a second fan 42, and a reversing device provided in the first aspect of this application. The housing 4 is provided with a first guide channel 4a and a second guide channel 4b that are isolated from each other, two air inlets 4c, and an air outlet 4d. The two air inlets 4c and the air outlet 4d are respectively located at the opposite openings of the first guide channel 4a and the second guide channel 4b. The first guide channel 4a is used to connect fresh air, and the second guide channel 4b is used to connect recirculated air. The first fan 41 is located in the first guide channel 4a. The second fan 42 is located in the second guide channel 4b. The reversing device is located between the two air inlets 4c and the first guide channel 4a and the second guide channel 4b. Among them, two ventilation openings 1a are connected to the opening of the first guide channel 4a, and the other two ventilation openings 1a are connected to the opening of the second guide channel 4b.

[0043] In one embodiment of this application, the first fan 41 is a fresh air fan, and the second fan 42 is a circulating air fan. The housing 4 has a first guide channel 4a and a second guide channel 4b that are isolated from each other, and these two channels are used to connect fresh air and circulating air, respectively. The housing 4 also has two air inlets 4c and two air outlets 4d, which are located at opposite openings of the first guide channel 4a and the second guide channel 4b, respectively. The first fan 41 is installed in the first guide channel 4a to drive the flow of fresh air; the second fan 42 is installed in the second guide channel 4b to drive the flow of circulating air. A reversing device is located between the two air inlets 4c and the first guide channel 4a and the second guide channel 4b, and is used to control the flow direction of fresh air and circulating air. The four ventilation openings 1a of the reversing device are respectively connected to the openings of the first guide channel 4a and the second guide channel 4b, wherein two ventilation openings 1a are connected to the first guide channel 4a, and the other two ventilation openings 1a are connected to the second guide channel 4b. In this way, the reversing device can flexibly switch the air intake direction of fresh air and circulating air. Even if the fresh air duct and the circulating air duct are connected in reverse, it can be easily adjusted. Or, in a specific environment, when the normal connection between the fresh air duct and the circulating air duct requires the use of duct loops or additional connecting components such as elbows and flexible hoses, the user can also adjust the air outlet through the reversing device so that the fresh air enters the first guide channel 4a and the circulating air enters the second guide channel 4b.

[0044] By integrating a reversing device into the air conditioner, flexible switching between fresh air and recirculated air is achieved, improving the air conditioner's versatility and adaptability. The four vents 1a of the reversing device are respectively connected to the first guide channel 4a and the second guide channel 4b, allowing for independent control of fresh air and recirculated air, avoiding mutual interference between the two airflows, and ensuring smooth and stable airflow. This design not only improves the air conditioner's efficiency and comfort but also enhances the system's reliability and flexibility.

[0045] Please see Figures 5 to 7 To prevent unnecessary mixing of fresh air and recirculated air after entering the housing 4, and to further enhance the connection stability between the baffle bracket 1 and the housing 4, a partition 43 is provided between the two air inlets 4c. The partition 43 connects the inner wall of the housing 4 and the baffle bracket 1.

[0046] In this embodiment, the partition 43 connects the inner wall of the housing 4 and the baffle support 1, forming a physical barrier to ensure that fresh air and recirculated air can maintain independent flow after entering the housing 4. Specifically, the partition 43 can be connected to the inner wall of the housing 4 and the baffle support 1 by welding, bolting, or other fixing methods. The material of the partition 43 is usually chosen to be the same metal material as the housing 4 and the baffle support 1 to ensure overall compatibility and durability.

[0047] This embodiment of the application significantly improves the performance and stability of the air conditioner by setting a baffle 43 between the two air inlets 4c. The baffle 43 not only prevents unnecessary mixing of fresh air and recirculated air after entering the housing 4, ensuring the independence and stability of airflow, but also further strengthens the connection stability between the baffle bracket 1 and the housing 4, improving the reliability of the entire system. This design effectively avoids air quality degradation and condensation problems that may result from airflow mixing. The baffle 43 ensures that fresh air and recirculated air remain independent after entering the air conditioning system, improving indoor air quality.

[0048] Please see Figures 4 to 7 In order to effectively mix the fresh air after being processed by the first guide channel 4a with the circulating air after being processed by the second guide channel 4b, a mixing chamber 4e is provided inside the housing 4. The mixing chamber 4e is connected to the first guide channel 4a, the second guide channel 4b and the air outlet 4d. The air conditioner includes a heat exchanger 44, which is located in the mixing chamber 4e.

[0049] In one embodiment, the mixing chamber 4e connects the first guide channel 4a, the second guide channel 4b, and the air outlet 4d to ensure that fresh air and recirculated air can be fully mixed after entering the mixing chamber 4e. The air conditioner also includes a heat exchanger 44, which is disposed within the mixing chamber 4e to regulate the temperature of the mixed air to achieve a set comfort level. Specifically, the mixing chamber 4e can be designed as an independent chamber located at the end of the housing 4 near the air outlet 4d, with its inlet connected to the first guide channel 4a and the second guide channel 4b, and its outlet connected to the air outlet 4d. The heat exchanger 44 can be a finned heat exchanger, using refrigerant or hot water for heat exchange to regulate the air temperature.

[0050] This embodiment of the application significantly improves the performance and comfort of the air conditioner by incorporating a mixing chamber 4e and a heat exchanger 44 within the housing 4. The design of the mixing chamber 4e allows for effective mixing of the fresh air processed by the first guide channel 4a and the recirculated air processed by the second guide channel 4b, ensuring air uniformity and comfort. The heat exchanger 44, located within the mixing chamber 4e, can regulate the temperature of the mixed air to achieve the set comfort level, thus improving the overall efficiency of the system. This design not only enhances the comfort of the air conditioner but also strengthens the system's energy efficiency and reliability.

[0051] Please see Figure 5 Since the composition of impurity particles in the fresh air and the circulating air is different, in order to filter the fresh air and the circulating air differently, the mixing chamber 4e is also equipped with a fresh air filter 45 and a circulating air filter 46. The fresh air filter 45 is located at the outlet of the first guide channel 4a, and the circulating air filter 46 is located at the outlet of the second guide channel 4b.

[0052] In this embodiment, the fresh air filter 45 and the circulating air filter 46 can be customized according to the composition and size of impurity particles in the fresh air and circulating air. For example, the fresh air filter 45 can use a high-efficiency particulate air (HEPA) filter to remove pollutants such as dust, pollen, bacteria, and viruses from outdoor air; the circulating air filter 46 can use an activated carbon filter to remove odors and volatile organic compounds (VOCs) from indoor air. These filters are fixed in the mixing chamber 4e by clips or bolts to ensure that they are securely installed and easy to replace. Specifically, the fresh air filter 45 is located at the outlet of the first guide channel 4a, and the circulating air filter 46 is located at the outlet of the second guide channel 4b to filter the fresh air passing through the first guide channel 4a and the circulating air passing through the second guide channel 4b, respectively. The fresh air filter 45 and the circulating air filter 46 can be designed to be detachable for convenient cleaning and replacement by the user.

[0053] This embodiment of the application significantly improves the filtration effect and air quality of the air conditioner by installing a fresh air filter 45 and a recirculating air filter 46 within the mixing chamber 4e. The fresh air filter 45 and the recirculating air filter 46 respectively filter different impurities in the fresh and recirculated air, ensuring that the air entering the mixing chamber 4e is purer. This design not only improves indoor air quality but also extends the service life of the heat exchanger 44 and other components, reducing maintenance costs. The fresh air filter 45 effectively removes pollutants from outdoor air, improving indoor air quality; the recirculating air filter 46 removes odors and harmful substances from indoor air, ensuring the health of users.
