[0002] With the improvement of people's living standards, wall-mounted air conditioners have become widely used in households. The indoor unit of a wall-mounted air conditioner is generally fixed to the interior wall using a wall-mounting panel. In related technologies, the upper end of the wall-mounting panel has a hook, and the rear wall of the air conditioner has a slot. The hook and slot cooperate to achieve the installation and positioning of the indoor unit. However, after the indoor unit is installed, a certain installation gap will remain between the upper wall of the indoor unit and the ceiling of the room, causing dust to easily accumulate on the top wall of the indoor unit and making it difficult to clean. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a wall-mounted air conditioner indoor unit that can eliminate the installation gap between the top surface of the unit casing and the top wall, making it easier for users to clean.

[0009] In some embodiments, the fixed channel extends in a horizontal direction.

[0010] In some embodiments, the fixed channel is provided with an opening at one end opposite to the housing.

[0011] In some embodiments, a side plate is connected between the horizontal plate and the vertical plate.

[0012] In some embodiments, the dimensions of the side panel gradually decrease along the left-right direction of the housing.

[0013] In some embodiments, the fixing base further includes reinforcing ribs disposed on at least one of the horizontal plate and the vertical plate.

[0029] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following is a reference appendix. Figures 1 to 6 This invention describes a wall-mounted air conditioner indoor unit according to an embodiment of the present invention.

[0031] like Figures 1 to 4 As shown, the wall-mounted air conditioner indoor unit of this utility model embodiment includes: a casing 1, a mounting base 2, and a hanging component 3. The casing 1 is provided with an air inlet 121 and an air outlet 122. There are at least two mounting bases 2, which are respectively arranged on the left and right sides of the casing 1. The upper end surface of the mounting base 2 is not higher than the top wall surface of the casing 1. Each mounting base 2 corresponds to at least one hanging component 3. The top end of the hanging component 3 is fixed to the top wall 4, and the bottom end of the hanging component 3 is fixed to the mounting base 2.

[0032] According to the embodiment of the present utility model, the wall-mounted air conditioner indoor unit has fixed seats 2 arranged on both sides of the casing 1 along its left and right directions, the top of the hanging component 3 is fixed to the top wall 4, and the bottom of the hanging component 3 is fixed to the fixed seat 2. Thus, the top wall surface of the casing 1 can be closely attached to the top wall 4, so that the air conditioner indoor unit can be installed close to the top.

[0033] like Figure 1 and Figure 2 As shown, the mounting base 2 is arranged near the top wall of the casing 1. By arranging the mounting base 2 near the top wall of the casing 1, the length of the hoisting component 3 can be reduced, making the installation structure of the air conditioner indoor unit simple and with good overall integrity.

[0034] Compared to the solution where "the mounting base 2 is arranged on the front and rear sides of the casing 1", the rear and top walls of the casing 1 in this embodiment can also be fitted with the wall, thereby reducing the installation space required for the indoor air conditioner and ensuring that the rear and top walls of the casing 1 are not prone to dust accumulation.

[0035] In addition, compared with the wall-mounted plate installation structure, the fixing base 2 of this utility model has a simpler structure, which can reduce the number of parts used and reduce the production and manufacturing costs. Furthermore, the air conditioner indoor unit is installed in a visible manner, which facilitates the positioning and fixing of the air conditioner indoor unit and helps to improve installation efficiency.

[0036] Therefore, the wall-mounted air conditioner indoor unit of this utility model can eliminate the installation gap between the top wall of the casing 1 and the top wall 4, as well as the installation gap between the rear wall of the casing 1 and the side wall of the wall, which is convenient for users to clean and has a simple structural design, which is conducive to improving the user experience.

[0037] It should be noted that the upper surface of the mounting base 2 of the wall-mounted air conditioner indoor unit of this utility model is not higher than the top wall surface of the casing 1. That is, the upper surface of the mounting base 2 can be flush with or slightly lower than the top wall surface of the casing 1. Therefore, when the top wall surface of the casing 1 is in contact with the top wall 4, the mounting base 2 will not interfere with the top wall 4. In other words, when the upper surface of the mounting base 2 is higher than the top wall surface of the casing 1, the top wall surface of the casing 1 and the top wall 4 cannot be completely in contact, resulting in a certain installation gap between the top wall surface of the casing 1 and the top wall 4, which is inconvenient for users to clean.

[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, the mounting base 2 includes a horizontal plate 21 and a vertical plate 22. The vertical plate 22 is connected to the side wall of the casing 1, and the horizontal plate 21 is connected to the vertical plate 22. The horizontal plate 21 extends horizontally away from the casing 1 and is fixed to the bottom end of the hanging component 3. It can be understood that the wall surface of the vertical plate 22 is orthogonal to the left-right direction of the casing 1, and the wall surface of the horizontal plate 21 is orthogonal to the up-down direction of the casing 1. By configuring the mounting base 2 with the above structure, the wall-mounted air conditioner indoor unit of this embodiment can ensure the connection strength between the mounting base 2, the base 11, and the wall, resulting in high reliability.

[0039] For example, the horizontal plate 21 is located at the upper end of the vertical plate 22. In the projection plane orthogonal to the front and rear directions of the casing 1, the connection structure between the horizontal plate 21 and the vertical plate 22 is generally inverted L-shape. Thus, after the indoor unit of the air conditioner is installed, the upper surface of the horizontal plate 21 can also be attached to the wall 4, thereby improving the stability of the mounting base 2 after installation, and also improving the appearance and overall integrity.

[0040] Optionally, a fixed channel 211 is provided on the horizontal plate 21, and the bottom end of the lifting component 3 passes through the fixed channel 211 in the vertical direction. This can improve the convenience of assembling the lifting component 3 with the horizontal plate 21.

[0041] In one example, the fixed channel 211 extends horizontally. It can be understood that, within a projection plane orthogonal to the vertical direction of the housing 1, the aperture profile of the fixed channel 211 is elongated. Thus, the lifting component 3 can move slightly horizontally relative to the fixed channel 21 to accommodate horizontal positional deviations of the lifting component 3.

[0042] For example, the fixed channel 211 extends horizontally along the left-right direction of the housing 1, and the fixed channel 211 is open at one end away from the housing 1. It can be understood that in the projection plane orthogonal to the vertical direction of the housing 1, the hole outline of the fixed channel 211 is roughly U-shaped. This facilitates pushing the lifting component 3 into the fixed channel 211 along the opening direction of the fixed channel 211, and also facilitates the processing and shaping of the fixed channel 211.

[0043] In another example, the fixed channel 211 can be a closed cylindrical channel, that is, the cross-section of the fixed channel 211 is circular.

[0044] Optionally, such as Figure 3 and Figure 4 As shown, a side plate 23 connects the horizontal plate 21 and the vertical plate 22. This further improves the structural strength and load-bearing capacity of the fixing base 2.

[0045] For example, the mounting base 2 includes two side plates 23, which are respectively arranged on both sides of the horizontal plate 21 along the front-rear direction of the housing 1, and the side plates 23 are connected to the vertical plate 22. In this embodiment of the present invention, the mounting base 2, by providing the side plates 23, can conceal and hide the structure of the hanging component 3. It is understood that when the user is looking directly at the indoor unit of the air conditioner, the side plates 23 on the mounting base 2 can conceal the structure of the hanging component 3, thereby improving the aesthetics and overall appearance of the installed indoor unit.

[0046] For example, such as Figure 4 As shown, the dimensions of the side plate 23 gradually decrease along the left-right direction of the housing 1 from top to bottom. It can be understood that the side plate 23 is generally triangular, with its pointed end facing downwards. In other words, the mounting base 2 has a generally wedge-shaped structure, which improves the structural strength of the mounting base 2 and extends its service life.

[0047] like Figure 5As shown, the lifting component 3 includes an expansion bolt 31 and a locking nut 32. The expansion bolt 31 passes through the fixing channel 211 along the vertical direction of the housing 1. The locking nut 32 is fitted onto the expansion bolt 31 and abuts against the lower end face of the horizontal plate 21. It can be understood that the upper end of the expansion bolt 31 is used to penetrate into the top wall 4, and the lower end of the expansion bolt 31 passes through the fixing channel 211. The locking nut 32 can be screwed onto the lower end of the expansion bolt 31 to abut against the lower end face of the horizontal plate 21. This improves the convenience of installing the indoor air conditioning unit and enhances its stability after installation.

[0048] During after-sales installation of the indoor unit of the air conditioner, first fix two sets of expansion bolts 31 on the top wall 4 of the room. Then, install the indoor unit of the air conditioner from bottom to top along the side wall of the room to the position of the expansion bolts 31. At this time, the two sets of expansion bolts 31 are respectively inserted into the fixing channels 211 of the left and right fixing seats 2. Then, tighten the locking nuts 32 at the lower end of the expansion bolts 31 and abut them against the lower end face of the horizontal plate 21. This allows the indoor unit of the air conditioner to be installed flush with the ceiling.

[0049] Optionally, such as Figures 3 to 5 As shown, the fixing base 2 also includes reinforcing ribs 24, which are disposed on at least one of the horizontal plate 21 and the vertical plate 22, thereby ensuring the structural strength of the fixing base 2 and improving its load-bearing capacity. For example, reinforcing ribs 24 are arranged on both the horizontal plate 21 and the vertical plate 22, and there can be multiple reinforcing ribs 24, which are arranged at intervals along a predetermined direction.

[0050] In some embodiments, such as Figures 3 to 5 As shown, the casing 1 includes a base 11 and a middle frame 12. The middle frame 12 is installed on the front side of the base 11. Both the air inlet 121 and the air outlet 122 are located on the middle frame 12. The side wall of the middle frame 12 has a clearance notch 123. The mounting bracket 2 passes through the clearance notch 123 and is connected to the base 11. Because the mounting bracket 2 is connected to the base 11, the connection strength between the mounting bracket 2 and the casing 1 is improved, reducing the risk of breakage at the connection point. Furthermore, since the mounting bracket 2 passes through the clearance notch 123, interference with the installation of the base 11 and the middle frame 12 is avoided, resulting in better overall integrity and an aesthetically pleasing appearance for the wall-mounted air conditioner indoor unit.

[0051] To prevent small animals such as insects and rodents from entering the housing 1 through the gap between the middle frame 12 and the fixing seat 2, the inner periphery of the clearance notch 123 can be fitted against the outer periphery of the fixing seat 2. For example, the inner periphery of the clearance notch 123 and the outer periphery of the fixing seat 2 can be fitted using a stepped surface contact method. Alternatively, a sealing ring can be provided between the inner periphery of the clearance notch 123 and the outer periphery of the fixing seat 2 to improve the sealing effect between them.

[0052] In one example, the fixing base 2 and the base 11 are integrally formed. That is, the fixing base 2 and the base 11 are a single structural component. For example, the fixing base 2 and the base 11 are integrally injection molded. This can improve the structural strength after the fixing base 2 and the base 11 are connected, and reduce the number of parts to be assembled, which is beneficial to improving production efficiency.

[0053] In other examples, the mounting base 2 and the base 11 can be fixed together by snap-fit ​​or threaded connection.

[0054] The number of mounting bases 2 can also be two or more. For example, there can be four mounting bases 2, with two mounting bases 2 arranged on the left side of the housing 1 and spaced apart in the front-to-back direction. The other two mounting bases 2 are arranged on the right side of the housing 1 and spaced apart in the front-to-back direction.

[0055] like Figure 3 As shown, the air inlet 121 is located on the bottom wall of the middle frame 12, and the air outlet 122 is located on the upper side of the front wall of the middle frame 12. Therefore, the indoor unit of the air conditioner in this embodiment of the present invention can be installed flush against the ceiling without affecting the air intake and exhaust of the indoor unit.

[0056] Understandably, since ambient air does not need to enter the interior of the air conditioner unit from directly above the middle frame 12, the installation gap between the air conditioner unit and the ceiling (i.e., the wall 4) can be eliminated, thereby improving the utilization rate of indoor space. Especially for rooms with low ceilings, this effectively reduces or eliminates the feeling of crampedness. Therefore, the air conditioner unit of this embodiment has very low requirements for installation space; the installation space only needs to be large enough to accommodate the air conditioner unit, without the need to leave air intake space above the unit, thus expanding the applicability of the air conditioner unit.

[0057] In this example of the present invention, both the evaporator and the impeller (not shown) are disposed inside the casing 1. The evaporator is located below the impeller and is arranged opposite to the air inlet 121. External airflow can enter the casing 1 through the air inlet 121, and after heat exchange with the wall of the evaporator, the heat-exchanged airflow can be discharged through the air outlet 122 under the guidance of the impeller.
