Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] In the field of air conditioning equipment technology, as users' requirements for indoor air quality increase, air conditioners with fresh air function are widely used. The fresh air module of the air conditioner usually purifies the outdoor air introduced through filter components.

[0003] In related technologies, the filter assembly is usually installed behind the front panel of the indoor unit. Users need to open the front panel and pull out the filter assembly from the mesh frame opening reserved on the outer cover. The operation steps are relatively cumbersome. Moreover, for wall-mounted indoor units, users need to stand at a height to apply force when disassembling the filter assembly, which makes disassembly more difficult. Utility Model Content

[0004] This application discloses an air conditioner that simplifies the disassembly process of the filter assembly and reduces the difficulty of disassembling the filter assembly.

[0005] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0006] Indoor unit, the indoor unit includes:

[0007] The housing has a fresh air inlet and a fresh air outlet. The housing includes a front panel and a rear panel that are arranged opposite to each other along its thickness direction. The front panel is configured to face the indoor side of the air conditioner, and the rear panel is configured to face the mounting side of the air conditioner.

[0008] The fresh air module includes:

[0009] The fresh air filter chamber is disposed inside the housing and has a first air inlet, which is connected to the fresh air inlet.

[0010] A fresh air volute is disposed inside the housing, and a fresh air duct is formed inside the fresh air volute. The air outlet of the fresh air duct is connected to the fresh air outlet. Along the thickness direction of the housing, the fresh air volute and the fresh air filter chamber are arranged side by side. A second air inlet is provided on the side wall of the fresh air volute facing the fresh air filter chamber. The fresh air duct is connected to the inner cavity of the fresh air filter chamber through the second air inlet.

[0011] The fresh air fan is disposed inside the fresh air volute. The fresh air fan is used to introduce outdoor air into the fresh air duct in sequence through the fresh air inlet, the first air inlet, and the second air inlet, and to send the air entering the fresh air duct to the indoor space through the fresh air outlet.

[0012] A filter assembly is arranged in the fresh air filter chamber along the arrangement direction of the fresh air filter chamber and the fresh air volute. The filter assembly is disposed in the fresh air filter chamber and located at the second air inlet, and is used to filter the air passing through the second air inlet.

[0013] The bottom of the housing is provided with a downward-facing disassembly port, through which the filter assembly can be inserted obliquely upward into the fresh air filter chamber from the indoor side toward the installation side.

[0014] Thus, by setting a downward-facing disassembly port at the bottom of the housing, the height for disassembling and assembling the filter assembly is lowered to within the natural reach of the human body. Users do not need to climb or bend over to operate the machine, which is especially suitable for wall-mounted indoor units, reducing the difficulty of operation. In addition, the design of the filter assembly being inserted diagonally upward from the front panel to the rear panel makes the insertion direction consistent with the natural force trajectory of the arm, which is ergonomic and requires less effort than the traditional horizontal or vertical pull-out method, making it easier for users to apply force when disassembling and assembling the filter assembly and reducing the difficulty of disassembly.

[0015] This application also provides an air conditioner, wherein the filter assembly includes:

[0016] Mounting rack;

[0017] A filter screen, which is detachably mounted on the mounting bracket, is used to filter the air passing through the first air inlet;

[0018] The fresh air volute has a connecting rail on its side wall facing the fresh air filter chamber. The connecting rail has a preset angle between its extension direction and the vertical direction. The preset angle is configured to allow the mounting bracket to be inserted into the connecting rail obliquely upward from the indoor side toward the mounting side.

[0019] In this way, by setting an insertion track on the side wall of the fresh air volute at a preset angle to the plane of the rear panel, the insertion direction of the filter component is limited to the upper angle, so that the direction of force applied during installation is consistent with the natural movement trajectory of the arm, which is ergonomic and more labor-saving than the traditional horizontal or vertical pull-out method.

[0020] This application also provides an air conditioner, wherein the mounting bracket is provided with a first positioning part;

[0021] A second positioning part is provided on the insertion track. When the mounting bracket is inserted into the insertion track along the oblique upper side, the second positioning part cooperates with the first positioning part to position the mounting bracket on the insertion track.

[0022] In this way, by cooperating with the first positioning part on the mounting bracket and the second positioning part on the insertion rail, accurate positioning can be ensured during the installation and removal of the filter component. When the mounting bracket is inserted into the insertion rail at an angle from above, the filter screen is fully aligned and tightly fitted with the second air inlet, preventing unfiltered air from entering the fresh air duct directly and improving filtration efficiency.

[0023] This application also provides an air conditioner, wherein the first positioning part includes an elastic arm, the elastic arm is disposed on the side wall of the mounting bracket, and the end of the elastic arm is provided with a positioning protrusion;

[0024] The second positioning part is a positioning groove provided in the insertion track. When the mounting bracket is inserted into the insertion track along the oblique upper side, the positioning protrusion springs into the positioning groove.

[0025] Thus, the cooperation between the flexible arm and the positioning groove provides clear installation feedback. When the positioning protrusion springs into the positioning groove, the user can confirm that the installation is in place by touch or sound ("click"), reducing the risk of misoperation. The flexible locking mechanism ensures that the mounting bracket will not loosen due to vibration or airflow impact during operation, maintaining a tight fit between the filter and the second air inlet, improving filtration efficiency. Disassembly only requires applying appropriate oblique force to unlock, making the operation simple and ergonomic, requiring no additional tools.

[0026] This application also provides an air conditioner, wherein the preset included angle ranges from 0° to 45°.

[0027] Thus, when the angle gradually increases to 45°, the insertion trajectory becomes obliquely upward. At this time, the direction of force is more in line with the natural upward pushing action of the arm when the human body is standing. This is especially suitable for wall-mounted indoor units. When users insert the component from the bottom obliquely upward, they do not need to bend over excessively or raise their arms, making the operation more effortless.

[0028] This application also provides an air conditioner, wherein the width of the second air inlet in the first direction is d, the mounting bracket is provided with a hollow part, the filter is installed in the hollow part, the width of the hollow part is h, wherein 0.8d≤h≤d, and the first direction is perpendicular to the insertion direction of the filter assembly.

[0029] In this way, the occlusion rate of the filter screen on the second air inlet is controlled within a reasonable range (occlusion area ≤ 20%). While ensuring that the filter screen completely covers the air inlet, sufficient air intake channels are retained, balancing filtration effect and ventilation efficiency. Furthermore, h ≥ 0.8d can avoid insufficient rigidity of the mounting bracket and unstable filter support due to the narrowness of the perforation, while h ≤ d can prevent material waste and structural redundancy, thereby reducing production costs.

[0030] This application also provides an air conditioner, wherein the thickness of the housing is D, wherein 190mm ≥ D ≥ 220mm;

[0031] The preset included angle ranges from 5° to 15°.

[0032] In this way, the thickness D of the housing is in the range of 190mm-220mm, which not only provides sufficient installation space for internal components (such as fans, heat exchangers, circuit modules, etc.) to ensure that each component operates normally and does not interfere with each other, but also avoids space occupation problems caused by excessive thickness. On this basis, the preset included angle is in the range of 5°-15° to ensure that oblique disassembly and assembly can be achieved, while avoiding excessive angle that would cause the disassembly and assembly port to move up to the front panel and affect the overall appearance of the front panel.

[0033] This application also provides an air conditioner, wherein a baffle is provided at the disassembly port, the baffle is hinged to the housing, and the baffle can close the disassembly port after the filter assembly is inserted into the fresh air filter chamber through the disassembly port.

[0034] In this way, the baffle sealing the disassembly port can effectively prevent dust and debris from entering the housing from the bottom opening, avoid the accumulation of foreign objects affecting the normal operation of the internal components of the fresh air module (such as fans and air ducts), and at the same time reduce indoor dust backflow through the disassembly port, thus maintaining indoor air quality.

[0035] This application also provides an air conditioner, wherein the baffle and the housing have a snap-fit ​​structure, and the baffle is detachably snapped onto the housing through the snap-fit ​​structure.

[0036] In this way, the snap-fit ​​structure can tightly connect the baffle to the housing, preventing the baffle from loosening or shifting due to airflow vibration or accidental contact during air conditioner operation. This ensures effective sealing of the disassembly port and prevents dust and debris from entering the air conditioner and affecting the normal operation of the fresh air module. In terms of ease of operation, the detachable snap-fit ​​method does not require tools, and users can quickly install and remove the baffle by hand, making it convenient to regularly open the baffle to maintain the filter components.

[0037] This application also provides an air conditioner, wherein the snap-fit ​​structure includes:

[0038] A snap-fit ​​protrusion is provided on the surface of the baffle facing the disassembly port and is located on the side opposite to the hinge shaft;

[0039] A resilient snap-fit ​​arm is disposed on the housing. When the baffle is rotated about the hinge axis toward the disassembly port, the snap-fit ​​protrusion can snap into the resilient snap-fit ​​arm.

[0040] The housing is provided with a press-to-release switch. When the baffle is pressed toward the housing, the press-type unlocking mechanism can apply a force away from the housing to the baffle, so that the snap-fit ​​protrusion disengages from the elastic snap-fit ​​arm in a direction away from the housing.

[0041] In this way, the pressing and releasing actions are integrated into the same position, which is ergonomic, provides clear operational feedback, and is simple to operate.

[0042] This application also provides an air conditioner, wherein the fresh air outlet is disposed at the bottom of the housing, a portion of the baffle covers the fresh air outlet, and a plurality of holes are uniformly disposed on the portion of the baffle covering the fresh air outlet.

[0043] In this way, the fresh air outlet is located at the bottom of the casing, and the baffle covers the outlet and has evenly distributed holes. The evenly distributed holes disperse the fresh air from the bottom outlet into multiple fine streams, avoiding airflow turbulence caused by excessive wind speed, allowing the fresh air to diffuse smoothly and reducing the discomfort of direct blowing. In addition, placing the fresh air outlet at the bottom of the casing saves space and is aesthetically pleasing. The removable baffle with the hole design makes it easy to clean accumulated dust.

[0073] 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, and 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.

[0074] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Unless otherwise stated, "a plurality of" means two or more.

[0078] As mentioned in the background section, in related technologies, the filter assembly is usually installed behind the front panel of the indoor unit. Users need to open the front panel and pull out the filter assembly from the mesh frame opening reserved in the outer cover. The operation steps are relatively cumbersome. Moreover, for wall-mounted indoor units, users need to stand at a height to apply force when disassembling the filter assembly, which makes disassembly more difficult.

[0079] To address the aforementioned issues, this application provides an air conditioner that lowers the height of filter assembly removal and installation to within the natural reach of the human body by providing a downward-facing removal port at the bottom of the housing. Furthermore, the filter assembly is designed to be inserted diagonally upwards from the front panel toward the rear panel, ensuring that the insertion direction aligns with the natural force trajectory of the arm, which is ergonomic. This method is more labor-saving than traditional horizontal or vertical pull-out methods, making it easier for users to apply force when removing or installing the filter assembly and reducing the difficulty of disassembly.

[0080] The following will describe specific embodiments and appendices. Figure 1-16 The technical solution of the air conditioner in this application will be further explained.

[0081] like Figure 1 As shown, air conditioner 1 may include an indoor unit 10. Air conditioner 1 is typically composed of an indoor unit 10 and an outdoor unit. The indoor unit 10 mainly undertakes the functions of air handling and indoor environment regulation. It contains components such as an evaporator and a fan. By circulating indoor air, the air exchanges heat with the evaporator to achieve cooling or heating. The outdoor unit mainly contains core components such as a compressor and a condenser. The compressor is responsible for compressing the refrigerant and circulating it within the air conditioning system. The condenser dissipates heat and condenses the high-temperature, high-pressure refrigerant gas into a liquid. The outdoor unit accelerates airflow through a fan to help the condenser dissipate heat efficiently. The indoor and outdoor units are connected through refrigerant pipes, power cords, and signal lines. They work together to transfer heat to meet the user's needs for regulating indoor environmental parameters such as temperature and humidity.

[0082] like Figures 2 to 5 As shown, the indoor unit 10 may include a housing 11, on which a fresh air inlet (not shown) and a fresh air outlet 11a are provided. The housing 11 includes a front panel 11b and a rear panel 11c arranged opposite to each other along its thickness direction. The front panel 11b is configured to face the indoor side of the air conditioner 1, and the rear panel 11c is configured to face the mounting side of the air conditioner 1.

[0083] like Figure 6 As shown, the indoor unit 10 may also include a fresh air module 100.

[0084] like Figure 7 and Figure 8 As shown, the fresh air module 100 may include a fresh air filter chamber 110, which is disposed inside the housing 11. The fresh air filter chamber 110 has a first air inlet 1101, which is connected to the fresh air inlet.

[0085] like Figure 7 and Figure 8As shown, the fresh air module 100 may further include a fresh air volute 120, which is disposed within the housing 11. A fresh air duct is formed within the fresh air volute 120, and the air outlet 1201 of the fresh air duct is connected to the fresh air outlet 11a. Along the thickness direction of the housing 11, the fresh air volute 120 and the fresh air filter chamber 110 are arranged side by side. A second air inlet 1202 is provided on the side wall of the fresh air volute 120 facing the fresh air filter chamber 110, and the fresh air duct is connected to the inner cavity of the fresh air filter chamber 110 through the second air inlet 1202. The fresh air volute 120 and the fresh air filter chamber 110 are arranged side by side along the thickness direction of the housing 11.

[0086] like Figure 8 As shown, the fresh air module 100 may also include a fresh air volute 120 and a fresh air fan 130. The fresh air fan 130 is disposed inside the fresh air volute 120. The fresh air fan 130 is used to introduce outdoor air into the fresh air duct in sequence through the fresh air inlet, the first air inlet 1101, and the second air inlet 1202, and to send the air entering the fresh air duct to the indoor space through the fresh air outlet 11a.

[0087] like Figure 7 and Figure 8 As shown, the fresh air module 100 may also include a filter assembly 140. Along the arrangement direction of the fresh air filter chamber 110 and the fresh air volute 120, the filter assembly 140 is disposed in the fresh air filter chamber 110 and located at the second air inlet 1202, for filtering the air passing through the second air inlet 1202.

[0088] like Figure 4 and Figure 5 As shown, the bottom of the housing 11 is provided with a downward-facing disassembly port 11d, through which the filter assembly 140 can be inserted into the fresh air filter chamber 110 from the front plate 11b toward the rear plate 11c at an oblique upward direction.

[0089] When the filter assembly 140 needs to be cleaned or replaced, the user can first reach their hand to the disassembly port 11d at the bottom of the housing 11, and apply force to the filter assembly 140 in a diagonally downward direction from the rear plate 11c to the front plate 11b, pulling it out of the disassembly port 11d and removing the filter assembly 140 from the second air inlet 1202 position in the fresh air filter chamber 110, thus completing the disassembly. After cleaning or replacement, the user can align the filter assembly 140 with the disassembly port 11d at the bottom of the housing 11 again, and push the filter assembly 140 in a diagonally upward direction from the front plate 11b toward the rear plate 11c, so that it is inserted into the fresh air filter chamber 110 through the disassembly port 11d and positioned at the second air inlet 1202, thus completing the installation.

[0090] Thus, by providing a downward-facing disassembly port 11d at the bottom of the housing 11, the disassembly and assembly height of the filter assembly 140 is lowered to within the natural reach of the human body. Users do not need to climb or bend over to operate the machine, which is especially suitable for wall-mounted indoor units 10 and reduces the difficulty of operation.

[0091] Furthermore, the design of the filter assembly 140 being inserted diagonally upwards along the front panel 11b toward the rear panel 11c ensures that the insertion direction aligns with the natural force trajectory of the arm, conforming to ergonomics. This is more labor-saving than the traditional horizontal or vertical pull-out method, making it easier for users to apply force when installing or removing the filter assembly 140 and reducing the difficulty of disassembly. In addition, since the installation and removal port 11d is located at the bottom of the housing 11, there is no need to reserve an opening on the front panel, maintaining the integrity of the front panel 11b. This solves the problem of appearance damage caused by reserved installation openings in integrated housing products. Moreover, the diagonally upward insertion trajectory extends along the thickness direction of the housing 11, occupying little space and adapting to the ultra-thin housing 11 design, thus improving the aesthetics and space utilization of the indoor unit 10.

[0092] In some possible embodiments, such as Figures 8 to 10 As shown, the filter assembly 140 may include a mounting bracket 1401. The mounting bracket 1401 may be provided with a handle that extends along the edge of the mounting bracket 1401.

[0093] The filter assembly 140 may include a filter screen (not shown in the figure), which is detachably mounted on the mounting bracket 1401. The filter screen is used to filter the air passing through the second air inlet 1202. The main function of the filter screen is to filter and purify the air passing through the second air inlet 1202. The filter screen is usually made of fiber fabric, activated carbon, or electrostatic adsorption materials, which can effectively intercept particulate matter such as dust, hair, pollen, and PM2.5, as well as some harmful components such as formaldehyde and odors in the air. For example, when outdoor air enters through the fresh air inlet, it needs to enter the fresh air filtration chamber 110 through the second air inlet 1202. At this time, the filter screen will filter the pollutants in the airflow layer by layer: large dust particles are intercepted by the outer coarse filter screen, fine particulate matter and allergens are captured by the medium or high efficiency filter screen, and the activated carbon layer adsorbs harmful gases and odors. Because the filter is removable, users can periodically remove it from the mounting bracket 1401 for cleaning or replacement to maintain filtration efficiency. After a period of use, a large amount of pollutants will accumulate on the surface of the filter. If it is not cleaned in time, it may lead to increased wind resistance, reduced fresh air volume, or even the growth of bacteria that affect indoor air quality. This removable design not only ensures the long-term use of the filter, but also makes it easy for users to replace different types of filters (such as HEPA filters) according to their air quality needs, thus improving the adaptability of the fresh air module 100.

[0094] like Figures 9 to 12As shown, a connecting rail 1203 is provided on the side wall of the fresh air volute 120 facing the fresh air filter chamber 110. The extending direction of the connecting rail 1203 has a preset angle with the vertical direction. The preset angle is configured such that the mounting bracket 1401 can be inserted into the connecting rail 1203 obliquely upward from the front plate 11b toward the rear plate 11c. Figure 9 The direction indicated by the middle arrow X.

[0095] When the filter assembly 140 needs to be disassembled for cleaning or replacement, the user can hold the end of the mounting bracket 1401 through the disassembly port 11d and apply force along the rear plate 11c towards the front plate 11b in a diagonally downward direction. This allows the mounting bracket 1401 to overcome the friction and positioning resistance of the insertion track 1203 and slide out along the insertion track 1203 until it is completely detached from the fresh air filter chamber 110. After cleaning or replacement, the user can first install the filter screen onto the mounting bracket 1401, and then align the mounting bracket 1401 with the disassembly port 11d at the bottom of the housing 11, so that the two sides of the mounting bracket 1401 are aligned with the insertion track 1203. Push the mounting bracket 1401 diagonally upward from the front plate 11b towards the rear plate 11c, so that it slides upward along the insertion track 1203 until the mounting bracket 1401 is fully inserted and positioned at the second air inlet 1202.

[0096] Thus, by setting an insertion track 1203 on the side wall of the fresh air volute 120 at a preset angle to the plane of the rear panel 11c, the insertion direction of the filter component 140 is limited to the upper angle, so that the direction of force applied during installation is consistent with the natural movement trajectory of the arm, which is ergonomic and more labor-saving than the traditional horizontal or vertical pull-out method.

[0097] In some possible embodiments, the preset included angle ranges from 0° to 45°.

[0098] When the preset angle is 0°, the insertion track 1203 extends horizontally, and the filter component 140 can be inserted along the horizontal direction from the front plate 11b to the rear plate 11c. At this time, the direction of force applied during operation is consistent with the thickness direction of the housing 11, and it cannot achieve the effect of effortless disassembly and assembly. When the angle gradually increases to 45°, the insertion trajectory becomes obliquely upward. At this time, the direction of force applied is more in line with the natural upward pushing action of the arm when the human body is standing, which is especially suitable for wall-mounted indoor units 10. When the user inserts the component obliquely upward from the bottom, there is no need to bend over excessively or raise the arm, making the operation more effortless.

[0099] In this embodiment, the range of the preset angle is limited to 0°-45°. A smaller angle (such as 0°-15°) is suitable for a thin housing 11, avoiding excessive vertical space occupied by the oblique insertion. A medium angle (15°-30°) balances the ease of operation and the compactness of the structure, and is suitable for most household scenarios. When it is close to 45° (30°-45°), the inclination of the insertion trajectory is the largest, the angle between the direction of force and the component of gravity is the smallest, the resistance that the user needs to overcome is the smallest, the operation is the easiest, and the oblique positioning can enhance the sealing fit between the filter component 140 and the second air inlet 1202, reducing the leakage of unfiltered air.

[0100] In some possible embodiments, see Figure 2 The thickness of the shell 11 is D, where 190mm ≥ D ≥ 220mm.

[0101] The preset angle range is 5°-15°.

[0102] The thickness D of the housing 11 is set within the range of 190mm-220mm. This provides sufficient installation space for internal components (such as fans, heat exchangers, circuit modules, etc.) to ensure that each component operates normally and does not interfere with each other. It also avoids space occupation problems caused by excessive thickness. In addition, this embodiment sets the preset included angle within the range of 5°-15° to ensure that oblique disassembly and assembly can be achieved while avoiding excessive angle that would cause the disassembly port 11d to move upward to the front panel 11b, affecting the overall appearance of the front panel 11b.

[0103] In some possible embodiments, such as Figure 10 and Figure 13 As shown, a first positioning part 1401a is provided on the mounting bracket 1401.

[0104] like Figure 14 and Figure 15 As shown, a second positioning part 1203a is provided on the insertion track 1203. When the mounting bracket 1401 is inserted into the insertion track 1203 along the oblique upper direction, the second positioning part 1203a cooperates with the first positioning part 1401a to position the mounting bracket 1401 on the insertion track 1203.

[0105] By engaging the first positioning part 1401a on the mounting bracket 1401 with the second positioning part 1203a on the insertion rail 1203, precise positioning can be ensured during the assembly and disassembly of the filter assembly 140. When the mounting bracket 1401 is inserted into the insertion rail 1203 at an angle from above, the filter screen is fully aligned and tightly fitted with the second air inlet 1202, preventing unfiltered air from directly entering the fresh air duct and improving filtration efficiency. At the same time, this positioning structure mechanically locks the mounting bracket 1401 to limit displacement and vibration during operation, especially the airflow impact generated by the operation of the fresh air fan 130. The positioning mechanism maintains stability, reducing noise and component wear caused by loosening, and extending service life. Furthermore, the positioning mechanism provides clear installation feedback to users, reducing the risk of misoperation. Even non-professionals can quickly complete disassembly and assembly, improving the user experience. During disassembly, the positioning structure's unlocking force is rationally designed, ensuring stability during use without adding extra difficulty, conforming to ergonomic design. Finally, the positioning mechanism allows for modular assembly of the filter assembly 140 and other components of the fresh air module 100, facilitating product iteration and maintenance, and reducing production and after-sales costs. This positioning structure, through a physical locking and guiding mechanism, improves filtration performance and operational stability while also considering user ease of operation and product maintenance efficiency.

[0106] In some possible embodiments, such as Figure 10 and Figure 13 As shown, the first positioning part 1401a includes an elastic arm, which is disposed on the side wall of the mounting bracket 1401, and a positioning protrusion is provided at the end of the elastic arm.

[0107] like Figure 14 and Figure 15 As shown, the second positioning part 1203a is a positioning groove provided in the insertion track 1203. When the mounting bracket 1401 is inserted into the insertion track 1203 at an angle upward, the positioning protrusion springs into the positioning groove.

[0108] During the process of inserting the mounting bracket 1401 into the insertion track 1203, the user first aligns the mounting bracket 1401 with the disassembly port 11d at the bottom of the housing 11, aligning the elastic arm on the side wall of the mounting bracket 1401 with the insertion track 1203, and pushes the mounting bracket 1401 diagonally upwards from the front plate 11b toward the rear plate 11c; during the pushing process, the positioning protrusion at the end of the elastic arm contacts and is pressed against the inner wall of the insertion track 1203, and the elastic arm undergoes elastic deformation and contracts toward the side wall of the mounting bracket 1401, causing the positioning protrusion to slide along the track; when the installation... When the bracket 1401 reaches the predetermined position, the positioning protrusion aligns with the positioning groove in the track, the elastic arm resumes its deformation, and the positioning protrusion springs into the positioning groove, completing the installation and achieving mechanical locking. When disassembling, the user only needs to apply force to the mounting bracket 1401 in the oblique downward direction of the rear plate 11c and the front plate 11b, so that the positioning protrusion is squeezed by the edge of the positioning groove, the elastic arm deforms and contracts again, the positioning protrusion is disengaged from the positioning groove, and the mounting bracket 1401 is pulled out in the oblique downward direction until it is completely removed from the fresh air filter chamber 110.

[0109] Thus, the cooperation between the flexible arm and the positioning groove provides clear installation feedback. When the positioning protrusion springs into the positioning groove, the user can confirm that the installation is in place by touch or sound ("click"), reducing the risk of misoperation. The flexible locking mechanism ensures that the mounting bracket 1401 will not loosen due to vibration or airflow impact during operation, maintaining a tight fit between the filter and the second air inlet 1202, improving filtration efficiency. Disassembly only requires applying appropriate oblique force to unlock, making the operation simple and ergonomic, requiring no additional tools.

[0110] Of course, the first positioning part 1401a and the second positioning part 1203a are not limited to the above forms. For example, the first positioning part 1401a is an elastic buckle provided on the side wall of the mounting bracket 1401, with a barb at the end of the buckle. The second positioning part 1203a is a slot in the insertion track 1203 that matches the buckle. There is a guide slope at the entrance of the slot. When inserted, the buckle elastically deforms along the slope and enters the slot, and the barb locks it. When disassembling, the buckle needs to be pressed to disengage it from the slot.

[0111] In some possible embodiments, such as Figures 9 to 11 The second air inlet 1202 has a width of d in the first direction. A perforated portion 1401b is provided on the mounting bracket 1401, and a filter screen is installed at the perforated portion 1401b. The width of the perforated portion 1401b is h, where 0.8d ≤ h ≤ d. The first direction is perpendicular to the insertion direction of the filter assembly 140. Figure 9 The direction indicated by the middle arrow Y. The second air inlet 1202 can be circular, rectangular, or other irregularly shaped; no limitation is made here.

[0112] When the width h of the perforated part 1401b is less than 0.8d, the area of ​​the mounting bracket 1401 blocking the second air inlet 1202 will be too large, which will significantly reduce the effective cross-sectional area of ​​the airflow through the filter, increase wind resistance, and cause a significant decrease in fresh air volume, affecting the indoor air exchange efficiency. At the same time, the fan needs to have greater power to overcome the resistance, increasing energy consumption and noise.

[0113] In this embodiment, the width h of the hollow part 1401b satisfies 0.8d≤h≤d to ensure that the occlusion rate of the filter on the second air inlet 1202 is controlled within a reasonable range (occlusion area ≤20%). Under the premise of ensuring that the filter completely covers the air inlet, sufficient air intake channels are retained, taking into account both filtration effect and ventilation efficiency. Furthermore, h≥0.8d can avoid insufficient rigidity of the mounting bracket 1401 and unstable filter support due to the hollow part 1401b being too narrow, while h≤d can prevent material waste and structural redundancy, thereby reducing production costs.

[0114] In some possible embodiments, such as Figure 4 As shown, a baffle 150 is provided at the disassembly port 11d. The baffle 150 is hinged to the housing 11 via the hinge shaft 1501. The baffle 150 can close the disassembly port 11d after the filter assembly 140 is inserted into the fresh air filter chamber 110 through the disassembly port 11d.

[0115] The baffle 150, which closes the disassembly port 11d, can effectively prevent dust and debris from entering the housing 11 through the bottom opening, avoid the accumulation of foreign objects that may affect the normal operation of the internal components (such as fans and air ducts) of the fresh air module 100, and at the same time reduce the backflow of indoor dust through the disassembly port 11d, thus maintaining indoor air quality.

[0116] Furthermore, the hinged design of the baffle 150 makes opening and closing operations convenient. When the user disassembles or installs the filter assembly 140, they only need to flip the baffle 150 without any additional tools. After the baffle 150 closes the disassembly and assembly port 11d, it can also maintain the integrity of the appearance of the housing 11 and prevent the bottom opening from damaging the overall aesthetics.

[0117] In some possible embodiments, the baffle 150 and the housing 11 have a snap-fit ​​structure, and the baffle 150 is detachably snapped onto the housing 11 by the snap-fit ​​structure.

[0118] After the user inserts the filter assembly 140 into the disassembly port 11d at an angle upward and installs it in place, the baffle 150 is flipped around the hinge axis to cover the disassembly port 11d. At this time, the snap-fit ​​structure (such as buckles, protrusions, etc.) on the baffle 150 is aligned with the corresponding slots, grooves, etc. on the housing 11. By gently pressing the baffle 150, the snap-fit ​​structure is snapped into the corresponding part of the housing 11, realizing a stable connection between the baffle 150 and the housing 11, and completing the closure of the disassembly port 11d. When it is necessary to open the disassembly port 11d, the user applies an unlocking force to the snap-fit ​​structure, such as pulling the baffle 150 downward. After the snap-fit ​​structure is unlocked, the baffle 150 is flipped open around the hinge axis to expose the disassembly port 11d, and then the filter assembly 140 can be disassembled.

[0119] Thus, the snap-fit ​​structure allows the baffle 150 to be tightly connected to the housing 11, preventing the baffle 150 from loosening or shifting due to airflow vibration or accidental contact during the operation of the air conditioner 1, ensuring effective sealing of the disassembly port 11d, and preventing dust and debris from entering the air conditioner 1 and affecting the normal operation of the fresh air module 100. In terms of ease of operation, the detachable snap-fit ​​method does not require tools, and users can quickly complete the installation and disassembly of the baffle 150 by hand, which is convenient for periodically opening the baffle 150 to maintain the filter assembly 140.

[0120] In some possible embodiments, such as Figure 16 As shown, the snap-fit ​​structure may include a snap-fit ​​protrusion 1601, which is disposed on the surface of the baffle 150 facing the disassembly port 11d and located on the side opposite to the hinge shaft 1501.

[0121] like Figure 5 As shown, the snap-fit ​​structure may also include an elastic snap-fit ​​arm 1602, which is disposed on the housing 11. When the baffle 150 is rotated about the hinge axis 1501 toward the disassembly port 11d, the snap-fit ​​protrusion 1601 can snap into the elastic snap-fit ​​arm 1602.

[0122] like Figure 5 As shown, a push-to-release switch 170 is provided on the housing 11. When the baffle 150 is pressed toward the housing 11, the push-to-release switch 170 can apply a force away from the housing 11 to the baffle 150, so that the locking protrusion 1601 disengages from the elastic locking arm 1602 in a direction away from the housing 11. The push-to-release switch 170 is provided with a spring-loaded push rod inside. One end of the push rod abuts against the baffle 150, and the other end is connected to a button facing the baffle 150. When the baffle 150 is pressed, the button triggers the push rod to release the spring potential energy. The push rod can push the baffle 150 away from the housing 11, so that the locking protrusion 1601 disengages from the elastic locking arm 1602.

[0123] After the user inserts the filter assembly 140 into the disassembly port 11d, the user rotates the baffle 150 around the hinge shaft 1501 to cover the disassembly port 11d. At this time, the snap-fit ​​protrusion 1601 on the baffle 150 slides along the guide slope of the elastic snap-fit ​​arm 1602 on the housing 11, causing the elastic arm to elastically deform. When the snap-fit ​​protrusion 1601 reaches the slot position of the elastic snap-fit ​​arm 1602, the elastic arm returns to its original deformation, and the snap-fit ​​protrusion 1601 snaps into the slot to complete the locking. During disassembly, the user moves the filter assembly 140 into the housing 11. Pressing the baffle 150 in the direction of body 11 triggers the release switch 170. The spring or elastic element inside the release switch 170 releases the thrust, causing the baffle 150 to rotate slightly around the hinge axis 1501. The locking protrusion 1601 disengages from the slot in the direction away from the housing 11, unlocking the baffle 150. The user can continue to rotate the baffle 150 to expose the disassembly port 11d. In this way, the pressing and releasing actions are integrated in the same position, which is ergonomic and provides clear operation feedback, making operation simple.

[0124] In some possible embodiments, such as Figure 3 As shown, the fresh air outlet 11a is located at the bottom of the housing 11, and a portion of the baffle 150 covers the fresh air outlet 11a. The portion of the baffle 150 covering the fresh air outlet 11a is provided with a plurality of holes 1502 evenly distributed.

[0125] Thus, the fresh air outlet 11a is located at the bottom of the housing 11, and the baffle 150 partially covers the outlet and has evenly distributed holes. The evenly distributed holes 1502 disperse the fresh air from the fresh air outlet 11a into multiple fine streams, avoiding airflow turbulence caused by excessive wind speed, allowing the fresh air to diffuse smoothly and reducing the discomfort of direct blowing. Furthermore, placing the fresh air outlet 11a at the bottom of the housing 11 saves space and is aesthetically pleasing. The removable baffle 150 with the hole design makes it easy to clean accumulated dust.

[0126] Of course, the number of fresh air outlets 11a is not limited to one. For example, two fresh air outlets 11a can be set, one facing upward and the other facing downward. Both fresh air outlets 11a can simultaneously deliver fresh air to the indoor space to increase the air volume.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the air conditioner of this application, and are not intended to limit it. Although the air conditioner of this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
