[0019] a pressing module, which is arranged at one end of the air conditioner air inlet away from the insertion slot, and is used for connection with the clamping piece;

[0020] a cleaning module, which is used for cleaning the filter screen;

[0021] the insertion block on the filter module is inserted into the insertion slot, the support frame is pressed, and the clamping piece is connected with the pressing module; when the clamping piece is connected with the pressing module, the support frame is pressed again, and the clamping piece is separated from the pressing module.

[0022] In the technical scheme, the structure design enables the air conditioner indoor unit to have perfect air filtering and convenient installation and disassembly functions. When the filter module needs to be installed, the insertion block is inserted into the insertion slot, so that one end of the filter module is limited. The end of the filter module close to the clamping piece is pressed downward, the clamping piece is aligned with the corresponding pressing module, the filter module is continuously pressed, the clamping piece is inserted into and connected to the pressing module. When the cleaning module needs to be removed, the filter module is pressed again, the clamping piece is separated from the corresponding pressing module, and the cleaning module can be taken out upward. The operation is simple, and the shell does not need to be disassembled, which is convenient for manual operation and improves the replacement and maintenance efficiency of the filter screen.

[0024] a mounting box, the top end of which is arranged in an open manner;

[0025] a elastic buckle, which is slidably connected to the mounting box, and the top of the elastic buckle is provided with a clamping cavity; when the elastic buckle is lowered into the mounting box, the clamping cavity is reduced in space and is used for clamping the clamping piece;

[0026] A limiting component for limiting the position of the elastic buckle in the mounting box.

[0027] In the technical scheme, the mounting box opening design in the pressing module and the elastic buckle structure are designed such that when the filter module is installed, the elastic buckle can slide in the mounting box by pressing the support frame, the top clamping cavity clamps the clamping piece, the filter module is quickly fixed, the operation is simple and efficient, the limiting component can accurately control the position of the elastic buckle, the connection stability is ensured, accidental falling is prevented, and the stability of the filter module during air conditioner operation is further ensured.

[0028] In some embodiments of the present application, the limiting component comprises:

[0029] A connecting rod, one end of which is rotatably connected to the elastic buckle;

[0030] A limiting rod arranged at the end of the connecting rod;

[0031] A limiting portion arranged on the inner wall of the mounting box; the limiting rod can move around the limiting portion;

[0032] A compression spring for pushing the elastic buckle towards the opening of the mounting box.

[0033] In the technical scheme, when pressed, the elastic buckle is pushed into the mounting box, the clamping cavity gradually narrows and clamps the clamping piece, and at the same time, under the action of the connecting rod and the limiting rod, the limiting rod gradually slides below the limiting portion, and stops pressing. Under the action of the compression spring, the elastic buckle is pushed upwards, and at this time, the limiting rod abuts below the limiting portion to limit the position of the elastic buckle in the mounting box, avoiding the top of the elastic buckle from separating from the mounting box to cause the clamping cavity to become larger to separate the clamping piece. After pressing again, under the action of the connecting rod, the limiting rod is separated from below the limiting portion, and after stopping pressing, under the action of the compression spring, the elastic buckle is pushed upwards, and the limiting rod passes from the side of the limiting portion. At this time, the top of the elastic buckle is separated from the mounting box, the clamping cavity becomes larger to separate the clamping piece and the elastic module.

[0034] In some embodiments of the present application, the limiting portion is triangular, and the side wall thereof facing the opening of the mounting box is inclined from the direction away from the opening of the mounting box to the direction of the width of the mounting box.

[0035] In the technical scheme, during the pressing of the support frame for installing the filter module, the limiting rod is guided to move along the inclined side wall, ensuring that it does not get stuck during movement, so as to facilitate smooth descent of the elastic buckle and accurate control of the position of the clamping cavity to clamp the clamping piece, improve installation accuracy and convenience, and reduce installation sticking or misplacement.

[0036] In some embodiments of the present application, the bottom wall of the limiting portion is concave towards the opening direction of the mounting box.

[0037] In the technical scheme, the limiting rod is clamped on the concave surface of the bottom wall of the limiting part, so that even if vibration occurs during installation or operation of the air conditioner indoor unit, the limiting rod can be tightly pressed against the highest point of the concave surface of the bottom wall of the limiting part under the action of the compression spring, and the limiting rod is prevented from being separated from the bottom of the limiting part. The connection stability of the pressing module and the clamping piece is ensured.

[0038] In some embodiments of the present application, the clamping piece comprises:

[0039] A connecting rod, one end of which is connected to the support frame;

[0040] A clamping block connected to the end of the connecting rod; the clamping block is used to be clamped in the clamping cavity.

[0041] In the technical scheme, the connecting rod and the clamping block structure of the clamping piece connect the clamping block to the support frame through the connecting rod, so that the clamping block can accurately correspond to the clamping cavity of the pressing module. During installation, as the support frame is pressed, the clamping block smoothly enters the clamping cavity and is fixed, ensuring that the filter module is tightly connected to the air conditioner air inlet, effectively preventing the filter module from loosening due to factors such as vibration, and maintaining stable filtering effect.

[0042] In some embodiments of the present application, the number of clamping pieces and pressing modules is multiple and one-to-one correspondence.

[0043] In the technical scheme, this layout can fix the filter module in all directions, disperse stress, avoid local stress concentration, make the filter module installation more stable, even in the case of long-time operation of the air conditioner and high-speed rotation of the fan causing vibration, it can also maintain good sealing performance and connection strength, and ensure the filtering effect.

[0044] In some embodiments of the present application, the number of insertion blocks and insertion grooves is multiple and one-to-one correspondence.

[0045] In the technical scheme, the insertion block is inserted into the insertion groove from one end of the support frame, and multiple-point insertion ensures that the filter module is accurately fixed in the horizontal direction and tightly fits the air conditioner air inlet, preventing the filter module from shifting, providing a precise alignment basis for the connection of the clamping piece and the pressing module, and ensuring the overall installation precision.

[0046] In some embodiments of the present application, the insertion blocks respectively tilt towards and away from the two sides of the shell from the direction away from the support frame.

[0047] In the technical scheme, the two sides of the plug block are inclined to each other from the direction away from the support frame, and the design has a guiding function. When the filter module is installed to the air conditioner air inlet, the inclined side guides the plug block to smoothly slide into the slot. After the filter module is inserted into the slot at an inclined angle, the angle is adjusted to be horizontal, which facilitates the connection of the pressing module and the clamping piece, and facilitates operation.

[0087] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0088] Please refer to all the drawings, in a schematic embodiment of the indoor unit of the air conditioner of the present application, the indoor unit of the air conditioner comprises a shell 100, the top of the shell 100 is provided with an air conditioner air inlet, the air conditioner air inlet is used for air passing and entering the shell 100.

[0089] In some embodiments, the indoor unit of the air conditioner comprises an indoor heat exchanger arranged inside the shell 100. The indoor heat exchanger is a key component for heat exchange in the air conditioning system. In the refrigeration mode, the refrigerant evaporates in the heat exchanger and absorbs the heat of the surrounding air.

[0090] In some embodiments, the air conditioner indoor unit comprises an indoor fan arranged inside the shell 100; the indoor fan causes the airflow to enter the shell 100 through the air conditioner air inlet and then enters the indoor through the indoor heat exchanger after heat exchange.

[0091] In some embodiments, the air conditioner indoor unit comprises a filter module arranged inside the shell 100. The filter module of the air conditioner is mainly used to purify the air entering the inside of the air conditioner, intercept dust, pollen, hair and other impurities in the air, and plays an important role in the normal operation of the air conditioner and the improvement of indoor air quality.

[0092] In some embodiments, the filter module comprises a support frame 200, a first steering rod 300, a second steering rod 400 and a filter screen 500. The first steering rod 300 is rotatably connected to one end inside the support frame 200. The second steering rod 400 is rotatably connected to one end inside the support frame 200 away from the first steering rod 300. The filter screen 500 is annular and is sleeved on the first steering rod 300 and the second steering rod 400. When the filter module is installed to the shell 100, the first steering rod 300 and the second steering rod 400 are located at both ends of the air conditioner air inlet, and jointly support the filter screen 500. The first steering rod 300 and the second steering rod 400 hold both ends of the filter screen 500, so that the annular filter screen 500 can be stretched straight and opened, maintaining a relatively flat and stable filtering plane, preventing the filter screen 500 from collapsing, wrinkling and other phenomena, and ensuring that the air can pass through each part of the filter screen 500 without obstruction, maintaining stable and efficient filtering effect.

[0093] In some embodiments, the filter module further comprises an insertion block 600 arranged at one end of the support frame 200 in the length direction. The air conditioner indoor unit further comprises a slot 700 arranged at one end of the air conditioner air inlet, and the slot 700 is used for insertion of the insertion block 600. The insertion block 600 is inserted into the slot 700 to realize the connection of one end of the filter module with the shell 100.

[0094] In some embodiments, the filter module further comprises a clamping piece 800 arranged at the bottom of the end of the support frame 200 away from the insertion block 600. The air conditioner indoor unit further comprises a pressing module 900 arranged at one end of the air conditioner air inlet away from the slot 700, and the pressing module 900 is used for connection with the clamping piece 800. The connection of the clamping piece 800 with the pressing module 900 realizes the connection of the other end of the filter module with the shell 100.

[0095] Insert the insertion block 600 on the filter module into the slot 700, press the support frame 200, and connect the clamping piece 800 with the pressing module 900; when the clamping piece 800 is connected with the pressing module 900, press the support frame 200 again, and separate the clamping piece 800 from the pressing module 900.

[0096] Through the above scheme, the structure design enables the air conditioner indoor unit to have perfect air filtering and convenient installation and disassembly functions. When the filter module needs to be installed, the plug 600 is inserted into the slot 700 to limit one end of the filter module. Pressing the filter module downward near the clamping piece 800, the clamping piece 800 is aligned with the corresponding pressing module 900, and the clamping piece 800 is inserted and connected to the pressing module 900 by continuously pressing the filter module. When the cleaning module needs to be removed, the clamping piece 800 is separated from the corresponding pressing module 900 by pressing the filter module again, and the cleaning module can be taken out upward. The operation is simple, and the shell 100 does not need to be disassembled, which is convenient for manual operation and improves the replacement and maintenance efficiency of the filter screen 500.

[0097] Please refer to all the drawings. In some embodiments, the length direction of the air conditioner air inlet is the same as the length direction of the shell 100. The length direction of the support frame 200 is the same as the length direction of the air conditioner air inlet. The operator can quickly align the plug 600 and the slot 700 according to the same direction feature, accurately install the filter module, save time, and the filter screen 500 can completely cover the air inlet to avoid air leakage and ensure the filtering effect.

[0098] In some embodiments, the air conditioner air inlet is arranged in a rectangular shape, and the support frame 200 is correspondingly arranged in a rectangular frame.

[0099] In some embodiments, the support frame 200 is arranged in a hollowed-out manner, and the first turning rod 300, the second turning rod 400 and the filter screen 500 are arranged inside the support frame 200. During installation and air conditioner operation, the support frame 200 protects the filter screen 500 from interference with other structures.

[0100] In some embodiments, the pressing module 900 includes a mounting box 901 and an elastic buckle 902. The top end of the mounting box 901 is arranged in an open manner. The elastic buckle 902 is slidably connected to the mounting box 901, and the top of the elastic buckle 902 is provided with a clamping cavity; when the elastic buckle 902 is lowered into the mounting box 901, the clamping cavity is reduced in size and used for clamping the clamping piece 800.

[0101] The open design of the mounting box 901 in the pressing module 900 and the structure of the elastic buckle 902 enable the elastic buckle 902 to slide in the mounting box 901 by pressing the support frame 200 during installation of the filter module, and the clamping piece 800 is clamped by the top clamping cavity, so that the filter module is quickly fixed, the operation is simple and efficient, the position of the elastic buckle 902 can be accurately controlled by the limiting assembly, the connection stability is ensured, accidental falling is prevented, and the stability of the filter module during air conditioner operation is further ensured.

[0102] Please refer to all the drawings, in some embodiments, the elastic buckle 902 includes two elastic pieces, and a clamping cavity is formed between the two elastic pieces. The two elastic pieces are close to the opening of the mounting box 901. The two elastic pieces are inclined away from each other in the direction of the card 800. That is, the clamping cavity is provided in a flared manner. When the elastic buckle 902 moves into the mounting box 901, the two elastic pieces gradually contact and deform the two side walls of the mounting box 901, respectively. As the elastic buckle 902 gradually moves, the angle between the two elastic pieces approaches parallel, so as to realize the reduction of the space of the clamping cavity, and the card 800 can be clamped. When the elastic buckle 902 gradually pushes out of the mounting box 901, the restriction of the side wall of the mounting box 901 on the elastic piece becomes smaller, and the two elastic pieces gradually recover under the action of elasticity, the clamping cavity gradually expands, and the card 800 can be separated from the clamping cavity.

[0103] In some embodiments, the end of the elastic piece is protruded or inclined to the other elastic piece. So that the two elastic pieces are in the shape of a pincer, to ensure that the card 800 clamped in the clamping cavity between the two elastic pieces will not be separated. Improve the stability of the connection.

[0104] In some embodiments, one side of the elastic buckle 902 is provided with a sliding block. The mounting box 901 is provided with a sliding groove for the sliding block to slide. The sliding block slides in the sliding groove, so as to avoid the disconnection of the elastic buckle 902 and the mounting box 901, and provide a certain guiding effect.

[0105] In some embodiments, the pressing module 900 further includes a limiting component for limiting the position of the elastic buckle 902 in the mounting box 901. So as to realize the fixation of the size of the clamping cavity.

[0106] Please refer to all the drawings, in some embodiments, the limiting component includes a connecting rod 903, a limiting rod 904, a limiting part 905 and a compression spring 906. The connecting rod 903 is rotatably connected to the elastic buckle 902 at one end. The limiting rod 904 is arranged at the end of the connecting rod 903. The limiting part 905 is arranged on the inner wall of the mounting box 901, and the limiting rod 904 can move around the limiting part 905. The compression spring 906 is used to push the elastic buckle 902 to the opening of the mounting box 901.

[0107] When pressing, the elastic buckle 902 is pushed into the mounting box 901, the clamping cavity gradually narrows and clamps the card piece 800, and at the same time, under the action of the connecting rod 903 and the limiting rod 904, the limiting rod 904 gradually slides below the limiting portion 905 and stops pressing. Under the action of the compression spring 906, the elastic buckle 902 is pushed upward, and at this time the limiting rod 904 abuts below the limiting portion 905 to limit the position of the elastic buckle 902 in the mounting box 901, avoiding the top of the elastic buckle 902 from separating from the mounting box 901 to cause the clamping cavity to become larger to separate the card piece 800. After pressing again, under the action of the connecting rod 903, the limiting rod 904 is separated from below the limiting portion 905, and after stopping pressing, under the action of the compression spring 906, the elastic buckle 902 is pushed upward, and the limiting rod 904 passes from the side of the limiting portion 905. At this time, the top of the elastic buckle 902 is separated from the mounting box 901, the clamping cavity becomes larger to separate the card piece 800 from the elastic module.

[0108] Please refer to all the drawings, in some embodiments, the compression spring 906 is arranged inside the mounting box 901, and the compression spring 906 is located between the bottom of the mounting box 901 and the elastic buckle 902. The bottom of the mounting box 901 is provided with a guide rod, and the compression spring 906 is sleeved on the guide rod. The compression spring 906 is limited by the guide rod to avoid bending and twisting, ensuring the stable pushing direction of the compression spring 906.

[0109] Please refer to all the drawings, in some embodiments, the limiting assembly further includes a rotating shaft, which is arranged at the end of the connecting rod 903 away from the limiting rod 904. The rotating shaft is parallel to the limiting rod 904. The elastic buckle 902 is provided with a shaft hole, and the rotating shaft is inserted and rotationally connected in the shaft hole. The rotating shaft realizes the rotational connection between the connecting rod 903 and the elastic buckle 902, and facilitates the installation of the elastic buckle 902 and the connecting rod 903 inside the mounting box 901.

[0110] In some embodiments, the limiting portion 905 is triangular, and the side wall thereof facing the opening of the mounting box 901 is inclined from the direction away from the opening of the mounting box 901 to the direction of the width of the mounting box 901. During the installation of the filter module and the pressing of the support frame 200, the limiting rod 904 is guided to move along the inclined side wall, ensuring that it does not jam during movement, so as to make the elastic buckle 902 descend smoothly and accurately control the position of the clamping cavity to clamp the card piece 800, improve the installation accuracy and convenience, and reduce the installation jamming or misplacement.

[0111] In some embodiments, the bottom wall of the limiting part 905 is concave to the opening direction of the mounting box 901. The limiting rod 904 is clamped on the concave surface of the bottom wall of the limiting part 905. Even if vibration occurs during installation or operation of the air conditioner indoor unit, the limiting rod 904 can be tightly pressed against the highest point of the concave surface of the bottom wall of the limiting part 905 under the action of the compression spring 906, avoiding the limiting rod 904 from disengaging from the bottom of the limiting part 905. The connection stability of the pressing module 900 and the clamping piece 800 is ensured.

[0112] In some embodiments, when the highest point of the concave surface of the bottom wall of the limiting part 905 is reached, the limiting rod 904 is located obliquely below the rotating shaft. That is, when the limiting rod 904 is clamped on the concave surface of the bottom wall of the limiting part 905, the connecting rod 903 is obliquely arranged. The connecting rod 903 is not vertical. Through this design, when the filter module is pressed again and released, the limiting rod 904 disengages from the bottom of the limiting part 905 and continues to move, and when the limiting rod 904 moves upward, it will contact the other side wall of the limiting part 905 and move upward along the side wall. During the entire movement process, the limiting rod 904 always rotates clockwise or counterclockwise around the limiting part 905.

[0113] Please refer to Figures 9 to 13 , Figure 9 is the state when the clamping piece 800 is not in contact with the elastic buckle 902. Figure 10 is the state when the filter module is pressed, and the limiting rod 904 gradually moves to the bottom end of the limiting part 905. Figure 11 is the state when the filter module is released, and the limiting rod 904 is abutted to the bottom of the limiting part 905 under the action of the compression spring 906, and at this time the clamping cavity clamps the clamping piece 800. Figure 12 is the state when the filter module is pressed again, and the limiting rod 904 disengages from the bottom of the limiting part 905. Figure 13 is the process of releasing the filter module, and the limiting rod 904 moves again to above the limiting part 905 under the action of the compression spring 906 to restore the initial state.

The clamping block is connected to the end of the connecting rod; the clamping block is used to be clamped in the clamping cavity. The structure of the connecting rod and the clamping block of the clamping piece 800 connects the clamping block to the support frame 200 through the connecting rod, so that the clamping block can accurately correspond to the clamping cavity of the pressing module 900. During installation, as the support frame 200 is pressed, the clamping block smoothly enters the clamping cavity and is fixed, ensuring that the filter module is tightly connected to the air conditioner inlet, effectively preventing the filter module from loosening due to factors such as vibration, and maintaining stable filtration effect.

[0115] Please refer to all the drawings, in some embodiments, the number of card pieces 800 and pressing modules 900 is multiple and one-to-one correspondence.

[0117] In some embodiments, the plug block 600 is inclined from the direction away from the support frame 200 towards and away from the two sides of the shell 100. The design of the plug block 600 inclined from the direction away from the support frame 200 towards and away from the two sides of the shell 100 has a guiding function. When installing the filter module to the air conditioner inlet, the inclined side guides the plug block 600 to smoothly slide into the plug slot 700. And the filter module can be inserted into the plug slot 700 at an inclined angle, and then adjusted to be horizontal, which is convenient for the connection of the pressing module 900 and the card piece 800, and convenient for operation.
