[0037] In the description of the present invention, “multiple” means two or more, and “several” means one or more.

[0038] The air conditioner indoor unit 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figures 1-10 As shown, the air conditioner indoor unit 1 according to the embodiment of the present invention includes a casing 10 , an indoor heat exchanger, an air guide assembly and a fresh filter element 20 .

[0040] The housing 10 is formed with an indoor air inlet, and a front panel 11 is constructed on the front side of the housing 10. An indoor heat exchanger is installed within the housing 10 for heat exchange with the indoor air. An air guide assembly is installed within the housing 10 and is used to drive the indoor air through the indoor heat exchanger for heat exchange. A filter mounting seat 110 is constructed on the rear side of the front panel 11 of the housing 10, and a fresh air filter 20 is mounted on the filter mounting seat 110. An air inlet cavity is formed between the front panel 11 and the fresh air filter 20, which is connected to the indoor air inlet. Among them, the filter mounting seat 110 is formed with a receiving groove 111, the fresh filter member 20 is installed on the filter mounting seat 110 and received in the receiving groove 111, and the short sides of the fresh filter member 20 on both sides are constructed with a first limiting edge 21, one side of the filter mounting seat 110 is constructed with a first blocking edge 112 and the other side is constructed with an elastic buckle 113, the first blocking edge 112 is formed at the notch of the receiving groove 111 and stops at the outer side of the first limiting edge 21 on one side, and the elastic buckle 113 is engaged with the outer side of the first limiting edge 21 on the other side.

[0041] For example, during the installation of the fresh filter 20, the fresh filter 20 needs to be tilted at a certain angle and inserted from the right to the left into the filter mounting seat 110. At this time, the first limit edge 21 passes through the middle part of the filter mounting seat 110. When the fresh filter 20 is gradually inserted into the filter mounting seat 110 to the left, the elastic buckle 113 will elastically deform to the right. The fresh filter 20 continues to be inserted into the filter mounting seat 110 until the fresh filter 20 is completely inserted into the filter mounting seat 110. The elastic buckle 113 will return to its state before deformation. During the disassembly process, the elastic buckle 113 can be pressed to the right to deform it. Then, the fresh filter 20 can be pulled to the right until the back of the fresh filter 20 overlaps the elastic buckle 113. The fresh filter 20 is then pulled to the right out of the filter mounting seat 110 to complete the complete disassembly of the fresh filter 20.

[0042] Similarly, you can first tilt the fresh filter 20 to the left at a certain angle and insert it into the first stop edge 112 of the filter mounting seat 110. Then press the right side of the fresh filter 20 into the filter mounting seat 110. The elastic buckle 113 will deform to the right. When the fresh filter 20 is fully inserted into the filter mounting seat 110, the elastic buckle 113 will return to its pre-deformation state. The disassembly process is the same as that of the above embodiment.

[0043] According to the air-conditioning indoor unit 1 of the embodiment of the present invention, at least one filter mounting seat 110 is constructed on the front side of the casing 100, and the fresh filter member 20 is installed on the filter mounting seat 110. Specifically, the short sides of the fresh filter member 20 on both sides are constructed with a first limiting edge 21, and the two sides of the filter mounting seat 110 are respectively constructed with a first stop edge 112 and an elastic clip 113. Compared with the traditional structure in which the fresh filter member 20 is fixed to the front panel 11 by fasteners, the complexity of installation and disassembly is reduced, and only the first stop edge 112 and the elastic clip 113 in the accommodating groove 111 are required. For example, the first gear edge 112 is located in the middle of the width direction of the filter mounting seat 110, which can limit the left side structure of the fresh filter component 20, and the elastic buckle 113 is a "door" shaped structure as a whole, which can cooperate with the right side structure of the fresh filter component 20 and limit the overall position of the fresh filter component 20, so that the user can easily disassemble and install the fresh filter component 20, facilitate cleaning and maintenance, and improve the convenience of operation and user experience.

[0044] In addition, indoor air first enters the air conditioner indoor unit 1 through the indoor air inlet 12 on the casing 10. The indoor air inlet 12 is located at the top of the air conditioner indoor unit 1. The incoming air first passes through the indoor air inlet 12 located at the indoor air inlet 12 for preliminary filtration. The air that has undergone initial filtration then flows into the air inlet cavity 13 formed between the front panel 11 and the fresh filter element 20. The air in the air inlet cavity 13 then flows to the fresh filter element 20 on the filter mounting seat 110 for deep purification. The filtered air continues to flow forward and is guided by the air guide assembly until it finally reaches the indoor heat exchanger. In the indoor heat exchanger, the air and the refrigerant exchange heat to achieve temperature regulation.

[0045] Compared with installing the fresh filter 20 at the top air inlet, installing the fresh filter 20 at the filter mounting seat 110 on the side of the front panel 11 does not occupy the air flow path, the air flow rate increases, thereby increasing the air filtration amount and achieving efficient filtration.

[0046] Therefore, the air conditioner indoor unit 1 according to the embodiment of the present invention has the advantages of improved disassembly and assembly convenience, large air filtration flow rate, etc.

[0047] In some specific embodiments of the present invention, Figure 4 As shown, the elastic buckle 113 includes an elastic arm 101 and a limiting rib 102. The elastic arm 101 is connected to the side wall of the filter mounting base 110 and extends to the outside of the receiving groove 111. The limiting rib 102 is connected to the side of the elastic arm 101 facing the freshness filter element 20. The thickness of the limiting rib 102 gradually decreases toward the outside of the receiving groove 111, and the limiting rib 102 engages the outside of the first limiting edge 21.

[0048] There may be multiple limiting ribs 102, spaced apart along the short sides of the filter mounting base 110. For example, the limiting ribs 102 may be triangular and form a buckle. The limiting ribs 102 are connected to the side of the elastic arm 101 facing the freshening filter 20. The thickness of the limiting ribs 102 gradually decreases toward the outside of the receiving groove 111. When the freshening filter 20 is installed, the limiting ribs 102 can smoothly slide over the first limiting edge 21. Once the freshening filter 20 is in place, the thicker portion of the limiting ribs 102 engages the outside of the first limiting edge 21, forming a secure locking mechanism. This prevents the freshening filter 20 from being accidentally dislodged due to inadvertent vibration or improper operation, ensuring the safety and stability of the freshening filter 20 during use. Furthermore, users can install and remove the freshening filter 20 manually without additional tools, greatly simplifying maintenance and improving operational convenience.

[0049] In addition, due to the elastic properties of its material, the elastic arm 101 will deform when subjected to external force, and will return to its original shape after the external force is removed, thus providing the necessary elastic support for the installation and removal of the fresh filter element 20. One end of the elastic arm 101 is connected to the side wall of the filter mounting seat 110, and the other end extends to the outside of the receiving groove 111. When the fresh filter element 20 is inserted into the receiving groove 111, the elastic arm 101 will be squeezed. After the fresh filter element 20 is fully in place, the rebound force of the elastic arm 101 will engage the limiting rib 102 on the outside of the first limiting edge 21, thereby achieving a stable installation of the fresh filter element 20. When the fresh filter element 20 needs to be removed, it only needs to apply a certain amount of force to overcome the resistance of the elastic arm 101, and the fresh filter element 20 can be easily removed.

[0050] In some specific embodiments of the present invention, Figure 3 As shown, the side wall of the filter mounting seat 110 is constructed with a hollow portion 105 suitable for the deformation of the elastic arm 101. The hollow portion 105 is located on the side of the limiting rib 102 away from the internal space of the accommodating groove 111. The length of the hollow portion 105 is greater than the length between the elastic arms 101. When the fresh filter element 20 is installed and removed, the elastic buckle 113 needs to undergo a certain degree of elastic deformation to allow the fresh filter element 20 to pass through or remain in a clamped state, ensuring that the elastic arm 101 can expand outward or contract inward without being hindered by the side wall. At the same time, the hollow portion 105 structure facilitates the removal and installation of the fresh filter element 200, improves the convenience of operation and saves operation time.

[0051] The hollow portion 105 increases the air circulation path, which helps improve the ventilation efficiency of the air conditioner indoor unit 1. Air can flow more smoothly through the hollow portion 105, reducing the resistance to air flow, thereby improving the filtering effect of the fresh filter element 20 and the overall performance of the air conditioner indoor unit 1.

[0052] In some specific embodiments of the present invention, Figure 5-10 As shown, the first limiting edge 21 is located on a side away from the front panel 11 in the thickness direction of the fresh filter element 20 , and the first blocking edge 112 is flush with the notch of the accommodating groove 111 .

[0053] The first stop edge 21 is located on the side of the freshness filter element 20, facing away from the front panel 11, in the thickness direction. It serves as a key boundary for the freshness filter element 20, ensuring that it is correctly installed. Its alignment with the notch of the receiving slot 111 effectively guides the installation of the freshness filter element 20, allowing it to be precisely aligned and secured within the receiving slot 111, preventing misalignment or movement of the freshness filter element 20. Furthermore, the structure of the first stop edge 21 increases the contact area between the freshness filter element 20 and the receiving slot 111 while maintaining a flush alignment, thereby improving installation stability and effectively preventing the freshness filter element 20 from shaking or shifting during use, ensuring that it remains correctly positioned and prevents any impact on the performance of the air conditioner indoor unit 1. Furthermore, the user simply inserts the freshness filter element 20 into the receiving slot 111 in an aligned manner. The first stop edge 21 and the first stop edge 112 interact with each other, simplifying the installation process and allowing users to more quickly replace or install the freshness filter element 20.

[0054] In some specific embodiments of the present invention, Figure 4 、 Figure 7 and Figure 8 As shown, the first retaining edge 112 includes a side retaining edge 103 and an angle retaining edge 104. The side retaining edge 103 is connected to the side wall of the receiving groove 111 of the filter mounting base 110. The side retaining edge 103 stops at the middle portion of the first limiting edge 21 at the notch of the receiving groove 111. The angle retaining edge 104 is connected to the corners of the receiving groove 111 of the filter mounting base 110. The angle retaining edge 104 stops at both ends of the first limiting edge 21 at the notch of the receiving groove 111.

[0055] For example, the corner stop edges 104 are symmetrically distributed in the upper and lower parts of the filter mounting seat 110, and are mainly used to cooperate with the two diagonal structures on the left side of the fresh filter element 20 to limit the position, and play a role in limiting the front and rear directions. The side stop edge 103 is mainly used to cooperate with the middle structure on the left side of the fresh filter element 20 to limit the position, and play a role in limiting the front and rear directions. When the fresh filter element 20 is installed in place, the side stop edge 103 and the corner stop edge 104 can ensure that the fresh filter element 20 is offset in the width direction. The side stop edge 103 and the corner stop edge 104 cooperate with the first limiting edge 21 to ensure the stability of the fresh filter element 20, and ensure that the fresh filter element 20 will not shake due to airflow or vibration when the air-conditioning indoor unit 1 is in operation, thereby ensuring the filtering effect and the stability of the air-conditioning indoor unit 1.

[0056] In addition, the corner stop 104 and the side stop 103 work together to simplify the installation process of the fresh filter 20. When installing the fresh filter 20, the user only needs to align the fresh filter 20 with the side stop 103 and the corner stop 104 to ensure that the fresh filter 20 is installed in the correct center position, reducing installation errors.

[0057] In some specific embodiments of the present invention, Figure 5 and Figure 6 As shown, the two long sides of the filter mounting base 110 are configured with second stop edges 114, which stop at both sides of the width direction of the freshness filter element 20. For example, the second stop edges 114 can be located in the middle of the two long sides of the filter mounting base 110. After the freshness filter element 20 is installed, it can ensure the stable fixation of the freshness filter element 20, avoid uneven force on the freshness filter element 20, and improve the stability and reliability of the installation of the freshness filter element 20.

[0058] The second edge 114 is symmetrically arranged, and the thickness between the second edge 114 and the accommodating groove 111 is basically the same as the thickness of the fresh filter element 20. When the fresh filter element 20 is installed, the second edge 114 can limit the middle position of the fresh filter element 20 in the length direction to ensure that the fresh filter element 20 can be firmly fixed in the filter mounting seat 110.

[0059] The contact between the second retaining edge 114 and both sides of the fresh air filter 10 further enhances the stability of the fresh air filter 20, preventing it from shaking due to airflow or vibration during operation of the air conditioner indoor unit 1. Furthermore, the second retaining edge 114 helps to create a better seal, reducing leakage of unfiltered air and ensuring that all air entering the air conditioner indoor unit 1 is filtered by the fresh air filter 20, thereby improving air quality and the energy efficiency of the air conditioner.

[0060] In some specific embodiments of the present invention, Figure 5 and Figure 6 As shown, the long sides of both sides of the fresh filter element 20 are constructed with second limiting edges 22, which extend continuously along the long sides where they are located and are connected to the first limiting edges 21 at both ends. The second blocking edge 114 stops at the outer side of the second limiting edge 22 at the notch of the accommodating groove 111.

[0061] The second limiting edge 22 is to ensure that the fresh filter element 20 can be accurately positioned on the filter mounting seat 110 of the air-conditioning indoor unit 1 during installation. The second limiting edge 22 extends continuously along the long side and is connected to the first limiting edge 21, forming a closed limiting structure, so that when the fresh filter element 20 is installed, the second limiting edge 22 can be accurately aligned with the second retaining edge 114 on the filter mounting seat 110, ensuring that the fresh filter element 20 does not undergo unnecessary displacement in the width direction. Similarly, the second limiting edge 22 extends continuously along the long side and is fixed by being connected to the first limiting edge 21, which can enhance the fixing stability of the fresh filter element 20. The provision of the second limiting edge 22 can effectively prevent the fresh filter element 20 from shaking or loosening during installation and use, ensuring that it is firmly placed in the corresponding position.

[0062] For example, the first limiting edge 21 and the second limiting edge 22 are arranged in a rectangular shape around the refreshing filter element 20. The left portion of the first limiting edge 21 cooperates with the corner stop edge 114 to limit the position. The middle portion of the first limiting edge 21 cooperates with the side stop edge 113 to limit the position, and the right portion of the first limiting edge 21 cooperates with the elastic buckle 113 to limit the position. The second limiting edge 22 cooperates with the second stop edge 114 to limit the width of the refreshing filter element 20.

[0063] The design structure of the second limiting edge 22 and the second stop edge 114 can make the installation process of the fresh air filter 20 simpler and smoother. This structure can guide the user to correctly install the fresh air filter 20, reduce the possibility of errors during the installation process, simplify the installation steps, and improve installation efficiency.

[0064] In some specific embodiments of the present invention, Figure 6 As shown, the long sides of the freshness filter 20 are configured with multiple stoppers 23. These stoppers 23 are spaced apart along their respective long sides, and the stoppers 23 engage the sidewalls of the receiving slot 111. The stoppers 23 are symmetrically distributed on both sides of the freshness filter 20, and are spaced apart and distributed on both sides of the second stop edge 114. When the freshness filter 20 is installed, the stoppers 23 abut against both sides of the receiving slot 111.

[0065] As part of the freshness filter element 20, the stopper 23 is installed by cooperating with the sidewalls of the receiving groove 111. One of its main functions is to provide a precise positioning point during installation, ensuring that the freshness filter element 20 is accurately positioned within the filter mounting base 110 and preventing the central filtering portion of the freshness filter element 20 from directly contacting the sidewalls of the receiving groove 111, which could cause damage. The stopper 23 cooperates with the receiving groove 111 on the filter mounting base 110 to secure the freshness filter element 20 and prevent it from shifting or vibrating during operation.

[0066] Arranging multiple limit blocks 23 at intervals along the long side can make it easier to align and fix the fresh filter element 20 in the correct position during installation. The presence of the limit blocks 23 can guide the user to correctly install the fresh filter element 20, reduce the risk of installation errors, and improve the accuracy and efficiency of installation. At the same time, the limit blocks 23 arranged at intervals can enhance the structural stability of the fresh filter element 20, especially on larger fresh filter elements 20. They can evenly distribute the pressure of the entire fresh filter element 20, preventing the fresh filter element 20 from being deformed or damaged by the impact of airflow, thereby ensuring the integrity and filtration efficiency of the fresh filter element 20.

[0067] In addition, the structure of the stop block 23 also makes it easier to maintain and replace the freshness filter 20. The user can easily remove and install the freshness filter 20 as needed, and the alignment of the stop block 23 ensures that the freshness filter 20 is correctly placed, saving time and effort in maintenance and replacement.

[0068] In some specific embodiments of the present invention, the fresh filter element 20 includes a coating mesh and an adsorption material. The adsorption material is coated by the coating mesh and is used to adsorb pollutants.

[0069] The coating mesh provides a framework for the adsorbent material, ensuring it maintains a certain shape and structure, preventing it from scattering or deforming. This allows the freshness filter to maintain its physical integrity, facilitating installation and removal. The coating mesh is typically made of a sturdy material, such as wire mesh or high-strength fiber mesh. It protects the adsorbent material from external forces, extending the filter's lifespan while preventing particles from falling off, maintaining indoor air quality. Furthermore, the coating mesh structure typically takes into account air flow resistance. Its pore size and distribution ensure smooth air flow through the filter, reducing wind resistance and improving the air conditioner's energy efficiency.

[0070] The adsorbent material is the core component of the fresh filter element 20. Its primary function is to capture and adsorb airborne pollutants, such as dust, pollen, smoke, bacteria, viruses, and odors, through physical adsorption or chemical reactions, thereby purifying the air and improving the indoor environment. Adsorbent materials typically have a large surface area and a porous structure, which increases their contact with pollutants, improves filtration efficiency, and ensures that harmful substances in the air are effectively removed. Certain adsorbent materials, such as silica gel and molecular sieves, can also absorb moisture from the air and regulate indoor humidity. Specially treated adsorbent materials, such as activated carbon, can eliminate odors and provide a more comprehensive air purification effect.

[0071] In some specific embodiments of the present invention, Figure 2 and Figure 3As shown, there are multiple fresh filter elements 20 and filter mounting seats 110 , and the multiple filter mounting seats 110 are arranged along the length direction of the housing 10 , and the fresh filter elements 20 are mounted on the filter mounting seats 110 in a one-to-one correspondence.

[0072] Since there are multiple fresh filter elements 20 and filter mounting bases 110, and they are installed one-to-one, the filtration area and filtration capacity of the air conditioner indoor unit 1 can be effectively increased. Through the combined filtering effect of multiple fresh filter elements 20, the filtering effect on dust, particulate matter and other impurities in the air can be enhanced, and the filtration efficiency of the air conditioner indoor unit 1 can be improved. At the same time, the multiple settings of the fresh filter elements 20 and the filter mounting base 110 can make the filtration load evenly distributed. Each fresh filter element 20 is supported and fixed by the corresponding filter mounting base 110, and some fresh filter elements 20 will not be overly stressed due to load concentration, which helps to extend the service life of the fresh filter element 20 and maintain stable filtration efficiency.

[0073] Each freshening filter 20 and its corresponding filter mounting base 110 function as an independent module. The multiple freshening filters 20 and filter mounting bases 110 facilitate maintenance and replacement of the freshening filters 20.

[0074] Other structures and operations according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0075] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0076] The compressor compresses high-temperature, high-pressure refrigerant gas and discharges the compressed gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0077] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0078] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0079] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in cooling mode.
