[0034] The air conditioner indoor unit 10 of this utility model is described below with reference to the accompanying drawings.

[0035] like Figures 1-8 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention includes a housing 100 and a filter 300.

[0036] An air inlet 111 is provided on the rear wall 110 of the housing 100, meaning that external air enters the housing 100 through the air inlet 111 on the rear wall 110 of the housing 100. A downward-facing mounting channel 200 is provided on the housing 100, meaning that the inlet 210 of the mounting channel 200 is located at the bottom of the housing 100 and is open downwards. The mounting channel 200 is located on the front side of the rear wall 110 of the housing 100, inside the air inlet 111; or, the mounting channel 200 is located on the rear side of the rear wall 110 of the housing 100, outside the air inlet 111.

[0037] The filter 300 includes a filter section 310 for filtering the airflow passing through it. The filter 300 is inserted into the mounting channel 200 through the inlet 210, and the filter section 310 is correspondingly disposed with respect to the air inlet 111. That is, the filter 300 can be inserted into the mounting channel 200 through the inlet 210, and when the filter 300 is installed in the mounting channel 200, the filter section 310 is correspondingly disposed with respect to the air inlet 111 so that the filter section 310 filters the airflow at the air inlet 111.

[0038] When installing the filter 300, insert the filter 300 upwards into the installation channel 200 through the inlet 210, so that the filter part 310 corresponds to the air inlet 111. When removing the filter 300, the user can pull the filter 300 out of the installation channel 200 through the inlet 210.

[0039] Compared with related technologies, in this embodiment of the air conditioner indoor unit 10, the air inlet 111 is located on the rear wall 110 of the housing 100. The housing 100 is provided with an installation channel 200 for installing a filter 300 with the inlet 210 facing downward. The installation channel 200 is located inside or outside the air inlet 111, and the inlet 210 of the installation channel 200 is open downward. The filter 300 can be directly inserted upward into the installation channel 200 through the inlet 210, so that the filter 300 is installed at a position corresponding to the air inlet 111; or, the filter 300 can be pulled downward from the installation channel 200 through the inlet 210, so that the filter 300 can be removed from the housing 100. Because the inlet 210 of the installation channel 200 is open downwards, the user can install and remove the filter screen 300 at a lower position, which reduces the difficulty of installing and removing the filter screen 300, thus making the installation of the filter screen 300 more convenient and improving the user experience.

[0040] In some embodiments, such as Figures 8-9 As shown, the filter section 310 includes a filter screen and a frame for supporting the filter screen. The filter screen can be an aluminum mesh, stainless steel mesh, non-woven fabric, fiber mesh, activated carbon filter screen, or other mesh structures.

[0041] In some embodiments, such as Figure 2 As shown, in this embodiment of the present invention, the installation channel 200 of the indoor unit 10 of the air conditioner is located on the outside of the air inlet 111, and the filter screen 300 is detachably installed on the outside of the air inlet 111 through the installation channel 200, so that the filter screen 300 filters the airflow that is about to enter the air inlet 111.

[0042] Specifically, such as Figure 2 As shown, the rear surface of the rear wall 110 of the housing 100 is provided with a first guide rail 150 extending in the vertical direction. There are two first guide rails 150, which are spaced apart in the horizontal direction. The right side of the left first guide rail 150 has a sliding groove that opens to the right and extends in the vertical direction, and the left side of the right first guide rail 150 has a sliding groove that opens to the left and extends in the vertical direction. The lower ends of both sliding grooves are open, and an installation channel 200 is defined between the two sliding grooves. Both ends of the filter screen 300 are inserted upward into the two sliding grooves through the lower ends of the two sliding grooves, so that the filter part 310 of the filter screen 300 corresponds to the air inlet 111.

[0043] In other embodiments, such as Figure 1As shown, in this embodiment of the present invention, the installation channel 200 of the air conditioner indoor unit 10 is disposed inside the air inlet 111, and the filter screen 300 is detachably disposed inside the air inlet 111 through the installation channel 200, so that the filter screen 300 filters the airflow entering the housing 100 from the air inlet 111.

[0044] Specifically, such as Figure 1 As shown, and with reference Figures 3-5 The indoor unit 10 of this embodiment of the air conditioner also includes a filter installation box 240. The filter installation box 240 is mounted on the housing 100, and at least defines an inlet 210 of the installation channel 200, located below the air inlet 111. This allows the filter 300 to be installed into the housing 100 through the filter installation box 240. In other words, the filter installation box 240 not only has at least an inlet 210 of the installation channel 200 inside, allowing the user to install and remove the filter 300 through the filter installation box 240, but also allows the filter installation box 240 to be detached from the housing 100, exposing some components installed inside the housing 100, such as refrigerant inlet pipes, refrigerant outlet pipes, or other components, so that the user can maintain and replace the components inside the housing 100.

[0045] The lower part of the rear wall 110 of the housing 100 is provided with a rearward-facing receiving groove 130, which is used to install a refrigerant inlet pipe, a refrigerant outlet pipe, or other components. A filter screen mounting box 240 is snap-fitted to the housing 100, and the filter screen mounting box 240 covers the opening 131 of the receiving groove 130. The receiving groove 130 has a snap-fit ​​groove at its opening, and the front surface of the filter screen mounting box 240 has a snap-fit ​​element that can snap-fit ​​with the snap-fit ​​groove. The filter screen mounting box 240 is installed in the opening 131 of the receiving groove 130 via the snap-fit ​​element and the snap-fit ​​groove, thus facilitating the installation and removal of the filter screen mounting box 240 cover.

[0046] Furthermore, such as Figure 5 and Figure 6 As shown, the installation channel 200 includes guide grooves 120 located on both sides of the air inlet 111, extending vertically. The upper end of the filter mounting box 240, i.e., the upper end of the inlet 210 of the installation channel 200, corresponds to the lower end of the guide groove 120. After the filter 300 passes through the inlet 210 of the installation channel 200, its left and right ends are respectively inserted into the two guide grooves 120. The two guide grooves 120 guide the filter 300 inserted into the housing 100, facilitating its proper installation.

[0047] Specifically, the front surface of the rear wall 110 of the housing 100 is provided with two second guide rails 160 extending in the vertical direction, spaced apart in the horizontal direction. A guide groove 120 opening to the right and extending vertically is provided on the right side of the second guide rail 160 on the left side, and a guide groove 120 opening to the left and extending vertically is provided on the left side of the second guide rail 160 on the right side. The lower ends of both guide grooves 120 are open, and the upper part of the mounting channel 200 is defined between the two guide grooves 120.

[0048] In some embodiments, such as Figure 4 As shown, the inlet 210 of the mounting channel 200 is flared downwards, meaning that the cross-sectional area of ​​the inlet 210 gradually increases from top to bottom. The inlet 210 of the mounting channel 200 is located at the bottom of the rear wall 110 of the housing 100, below the air inlet 111. This facilitates the installation and removal of the filter 300. Furthermore, the larger lower end of the inlet 210 makes it easier for users to identify, further improving its practicality.

[0049] Specifically, the front wall surface 220 and / or the rear wall surface 230 of the inlet 210 of the mounting channel 200 are inclined. When the front wall surface 220 of the inlet 210 of the mounting channel 200 is inclined, the upper end of the front wall surface 220 of the mounting channel 200 is closer to the rear wall surface 230 of the inlet 210 of the mounting channel 200 relative to its lower end; when the rear wall surface 230 of the inlet 210 of the mounting channel 200 is inclined, the upper end of the rear wall surface 230 of the inlet 210 of the mounting channel 200 is closer to the front wall surface 220 of the inlet 210 of the mounting channel 200 relative to its lower end.

[0050] For example Figure 4 As shown, the front wall 220 of the inlet 210 of the mounting channel 200 is an arc surface that extends downward and bends forward, and the rear wall 230 of the inlet 210 of the mounting channel 200 is a plane that extends downward.

[0051] In some embodiments, such as Figure 4 As shown, the filter screen 300 also includes a mating part 320, the upper end of which is connected to the lower part of the filter screen part 310, and the mating part 320 engages with the mounting channel 200. The filter screen 300 is connected to the mounting channel 200 via its mating part 320, thereby further reducing the operational difficulty of installing and removing the filter screen 300, thus making the installation of the filter screen 300 more convenient.

[0052] Furthermore, a slot 231 is provided on the front or rear wall of the mounting channel 200, and a protrusion 323 is provided on the mating part 320, the protrusion 323 being inserted into the slot 231. That is, the slot 231 is provided on the front wall of the mounting channel 200, and the protrusion 323 is provided on the rear wall of the mating part 320; or, the slot 231 is provided on the rear wall of the mounting channel 200, and the protrusion 323 is provided on the front wall of the mating part 320. This not only achieves a snap-fit ​​connection between the mating part 320 and the mounting channel 200, reducing the operational difficulty when installing or removing the filter screen 300, but also results in a simple structure that is easy to manufacture.

[0053] Specifically, the rear wall of the mounting channel 200 is vertically oriented, meaning it is a downwardly extending plane. A slot 231 is provided on the rear wall of the mounting channel 200. A rearwardly extending stop 321 is provided at the lower end of the mating part 320; a protrusion 322 is provided on the upper side of the stop 321, and a protrusion 323 is formed on the upper end of the protrusion 322. The protrusion 322 has a certain degree of elasticity and can undergo elastic deformation under force. When the mating part 320 is inserted into the inlet 210 of the mounting channel 200, the protrusion 323 on the protrusion 322 is squeezed by the rear wall of the mounting channel 200, causing the protrusion 322 to bend, allowing the mating part 320 to smoothly insert into the mounting channel 200 until the protrusion 323 engages with the slot 231. When the mating part 320 is pulled out from the inlet 210 of the installation channel 200, the protrusion 323 on the protrusion 322 is squeezed by the rear wall of the installation channel 200, causing the protrusion 322 to bend, so that the mating part 320 can be smoothly pulled out of the installation channel 200. This further reduces the difficulty of installing and removing the filter screen 300, allowing the filter screen 300 to be smoothly pulled out of the installation channel 200 or smoothly inserted into the installation channel 200, thus improving the user experience.

[0054] In some embodiments, such as Figures 4-9 As shown, a positioning rib 330 is provided on the front or rear wall surface of the mating part 320. The positioning rib 330 contacts and abuts against the corresponding wall surface of the mounting channel 200, and the other wall surface of the mating part 320 contacts and abuts against the other wall surface of the mounting channel 200. That is, the positioning rib 330 is provided on the front wall surface of the mating part 320, and the positioning rib 330 contacts and abuts against the rear wall surface of the mounting channel 200, and the rear wall surface of the mating part 320 contacts and abuts against the front wall surface of the mounting channel 200; or, the positioning rib 330 is provided on the rear wall surface of the mating part 320, and the positioning rib 330 contacts and abuts against the front wall surface of the mounting channel 200, and the front wall surface of the mating part 320 contacts and abuts against the rear wall surface of the mounting channel 200.

[0055] When the positioning rib 330 and the other wall of the mating part 320 come into contact with the corresponding wall of the mounting channel 200, the mating part 320 is restricted by the mounting channel 200 and cannot continue to move upward, thereby ensuring that the filter part corresponds to the air inlet 111 in the vertical direction.

[0056] In other embodiments, such as Figures 4-9 As shown, positioning ribs 330 are provided on both the front and rear walls of the mating part 320, and the positioning ribs 330 contact and abut against the corresponding walls of the mounting channel 200. Positioning ribs 330 are also provided on both the rear and front walls of the mating part 320; one positioning rib 330 contacts and abuts against the front wall of the mounting channel 200, and the other positioning rib 330 contacts and abuts against the rear wall of the mounting channel 200.

[0057] In some embodiments, such as Figures 4-9 As shown, the air inlet 111 includes multiple inlets, and the multiple air inlets 111 are arranged in the lateral direction (e.g., Figure 3 The air inlet 100 is arranged at intervals (left and right). Multiple installation channels 200 are provided, and the portions of these channels below the air inlet 111 are interconnected. Multiple filters 300 are also provided, each inserted into one of the installation channels 200. In other words, multiple air inlets 111 are provided on the rear wall 110 of the housing 100, increasing the air intake volume of the indoor unit 10 in this embodiment. Furthermore, by providing filters 300 corresponding to the multiple air inlets 111, the air delivery quality of the indoor unit 10 is ensured.

[0058] In some embodiments, such as Figure 1 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention also includes a cross-flow fan 400 and a heat exchanger 500. The cross-flow fan 400 is disposed in the inner cavity and configured to promote the airflow entering the inner cavity through the air inlet 111. The heat exchanger 500 is disposed in the inner cavity and configured to exchange heat with the airflow entering the inner cavity. An air outlet 141 is provided on the front wall 140 of the housing 100, and the cross-flow fan 400 and the heat exchanger 500 are located between the air inlet 111 and the air outlet 141.

[0059] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
