[0037] In the existing air conditioner design, the air conditioner indoor unit is usually equipped with universal wheels to facilitate movement and position adjustment. However, when the air conditioner indoor unit is used for a long time, the design of the universal wheel has some problems. First, the support points of the universal wheel are relatively few and mainly concentrated around the chassis, which leads to the air conditioner indoor unit to easily shake due to uneven force on uneven ground. Second, the design of the universal wheel is mainly to facilitate movement, rather than to provide stable support, so its support effect is not ideal when used for a long time. In addition, the chassis, as the core support structure of the air conditioner indoor unit, needs to bear the weight of the entire machine and the vibration during operation, and the design of the universal wheel has certain limitations in stability and load-bearing capacity.

[0038] Therefore, the present application provides an air conditioner, which improves the stability and load-bearing capacity of the air conditioner indoor unit during long-term fixed use by improving the chassis assembly.

[0039] Please refer to Figures 1 to 4 In an embodiment of the present application, the air conditioner comprises an air conditioner indoor unit 100 and an air conditioner outdoor unit (not shown in the figure), and a flexible refrigerant pipe (not shown in the figure) serves to connect the air conditioner indoor unit 100 and the air conditioner outdoor unit. The two ends of the flexible refrigerant pipe are connected with the refrigerant interfaces of the air conditioner indoor unit 100 and the air conditioner outdoor unit respectively to ensure smooth flow of the refrigerant. The flexible refrigerant pipe is usually composed of multiple layers of materials, including an inner refrigerant pipeline, a middle layer of thermal insulation material and an outer protective sleeve. This structure not only ensures efficient transmission of the refrigerant, but also improves the durability and safety of the pipeline. Compared with traditional rigid pipelines, the flexible refrigerant pipe has better flexibility and adaptability. The introduction of the flexible refrigerant pipe makes the installation of the air conditioner more flexible and convenient. Users can freely adjust the length and bending degree of the pipeline according to actual needs to adapt to different installation conditions. In addition, the flexible refrigerant pipe also has good thermal insulation performance, reducing the energy loss of the refrigerant and improving the energy efficiency ratio of the air conditioner.

[0040] The air conditioner indoor unit 100 comprises a chassis assembly 200, which is the core support structure of the air conditioner indoor unit 100, mainly comprising a chassis 300 and a bottom foot 400; the chassis 300 has a bottom surface 301 facing the ground; the chassis 300 has a bottom surface 301 facing the ground, and a mounting surface corresponding to the bottom surface 301, which is used to support parts such as condenser, fan, water pump, etc.

[0041] The bottom foot 400 is arranged on the bottom surface 301, and the number is multiple, and is arranged dispersedly, such as a triangle, a quadrilateral, etc., to provide stable support for the chassis 300 and prevent the air conditioner indoor unit 100 from shaking during operation. Compared with the existing universal wheel, the design of the bottom foot 400 is more stable and can adapt to different ground conditions. The number and dispersed arrangement of the bottom foot 400 improve the load-bearing capacity and anti-overturning performance of the air conditioner indoor unit 100, making the air conditioner indoor unit 100 more stable during long-term fixed use.

[0042] In addition, the bottom foot 400 is arranged on the bottom surface 301, and the stress direction is vertically transmitted to the chassis 300, so that the air conditioner indoor unit 100 is more stable during fixed use, and the shaking caused by uneven ground or uneven stress is reduced. In addition, the number and dispersed arrangement of the bottom foot 400 also improve the load-bearing capacity and anti-overturning performance of the air conditioner indoor unit 100, making the user more at ease during use.

[0043] Specifically, the air conditioner indoor unit 100 and the air conditioner outdoor unit can be integrally arranged, at this time the air conditioner is a mobile air conditioner, which does not need an external exhaust pipe or an outdoor unit, and all components are integrated in one unit; but not limited to this, in an embodiment, the air conditioner indoor unit 100 and the air conditioner outdoor unit are connected through a flexible refrigerant pipe, and the flexible refrigerant pipe is pre-filled with refrigerant medium before leaving the factory, so that the user does not need to ask a special worker to fill the refrigerant after purchase, solving the use cost of the user. In this way, when the user installs the equipment himself, he only needs to fix the air conditioner indoor unit 100 and the air conditioner outdoor unit respectively, without the need to assemble the refrigerant pipe and add refrigerant, thereby solving the installation difficulty and realizing personal installation of the user. In addition, in an embodiment, the compressor is arranged in the air conditioner indoor unit, and after arranging the compressor in the air conditioner indoor unit, the weight of the air conditioner outdoor unit can be reduced, so that the user can move the air conditioner outdoor unit more conveniently to find a suitable installation position, solve the installation difficulty, solve the labor cost, especially in areas where the labor cost is high. Correspondingly, in order to solve the noise, the compressor arranged in the indoor unit is subjected to noise reduction treatment, such as filling of noise reduction material; a buffer structure is arranged to solve the vibration transmission of the compressor.

[0044] In the embodiment, a foot 400 is arranged at each corner of the bottom surface 301 to provide stable support and prevent the air conditioner indoor unit 100 from shaking during operation. Of course, in other embodiments, the feet 400 can also be arranged in a triangular shape on opposite sides of the bottom surface 301, preferably on the long sides.

[0045] Specifically, the end surface of the foot 400 away from the bottom surface 301 is arranged in a plane. The plane of the foot 400 has a relatively large contact area with the mounting surface (such as the ground, a bracket, etc.), which can provide more uniform support and make the foot 400 more stable when bearing the weight of the air conditioner indoor unit 100, thereby reducing the likelihood of deformation or damage and improving the load-bearing capacity and service life of the air conditioner indoor unit 100.

[0046] In addition to being arranged in a plane, the end surface of the foot 400 away from the bottom surface 301 can also have other shapes or structures, such as a conical shape, a spherical shape, an arc shape, etc. However, these shapes or structures may not be as superior as the plane arrangement in some aspects. For example, a conical or spherical end surface can result in a reduced contact area with the mounting surface, thereby affecting stability; an arc-shaped end surface can not be easily aligned with the mounting surface during installation, increasing the difficulty of installation. In contrast, a planar end surface has more obvious advantages in terms of stability, ease of installation, and load-bearing capacity. Preferably, the foot 400 is configured as a cylinder; additionally, to make the foot 400 more aesthetically pleasing, the connection between the outer peripheral surface of the foot 400 and the end surface away from the bottom surface 301 is arc-shaped.

[0047] To facilitate installation, the foot 400 and the bottom plate 300 are detachably connected; using detachable connection allows the foot 400 to be easily removed and replaced when needed. Detachable connection can be achieved in various ways, such as slot connection, threaded connection, etc. Slot connection is achieved by inserting the foot 400 into a pre-designed slot on the bottom plate 300 and securing it with a buckle or locking device; threaded connection is achieved by using threads to tightly connect the foot 400 and the bottom plate 300 together.

[0048] Specifically, the foot 400 and the bottom plate 300 are locked and fixed by a screw 500. Screw 500 locking and fixing is a common and reliable connection method that can ensure a firm connection between the foot 400 and the bottom plate 300 and is not prone to loosening. This connection method performs well when bearing a large load and can provide stable support.

[0049] The locking form of screw 500 locking and fixing is various, including direct locking, pre-buried nut locking, etc. Direct locking is achieved by screwing the screw 500 directly into the threaded hole 410 on the bottom plate 300 to fix the foot 400; pre-buried nut locking is achieved by pre-installing a nut on the bottom plate 300 and then screwing the screw 500 into the nut to fix the foot 400.

[0050] Referring toFigure 4 Specifically, the end surface of the foot 400 close to one end of the bottom surface 301 is provided with a threaded hole 410, and the bottom plate 300 is provided with a mounting hole 310 corresponding to the threaded hole 410, and the bottom plate 300 and the foot 400 are screwed through the mounting hole 310 and the threaded hole 410 by the screw 500. Only the screw 500 needs to pass through the mounting hole 310 of the bottom plate 300 and be screwed into the threaded hole 410 of the foot 400, so that quick fixing can be realized. This installation method does not require complex tools or technology, and reduces the installation difficulty and cost.

[0051] In addition, the screw 500 is not visible on the bottom surface 301 of the bottom plate 300, which can form a high-strength connection, effectively resist the vibration and impact force generated during the operation of the air conditioner indoor unit 100, and ensure that the foot 400 and the bottom plate 300 will not loosen or fall off, and also ensure the aesthetic appearance.

[0052] Preferably, the foot 400 is configured as an injection molded part; in one embodiment, the foot 400 is a standard part, and the length of the foot 400 is the same; in another embodiment, in order to adapt to the shape of the bottom plate 300, and also to make the bottom plate 300 supported by the foot 400 remain horizontal, the length of the foot 400 is different; further, in order to prevent the foot 400 of different lengths from being installed incorrectly, a foolproof structure is further provided between the bottom plate 300 and the foot 400, such as a sunken groove or a mark at the installation position of the foot 400 with a longer length.

[0053] In combination with Figure 1 and Figure 4 Further, the periphery of the bottom surface 301 is provided with a downward shielding flange 320, which can shield part of the foot 400 and improve the overall aesthetic appearance of the air conditioner indoor unit 100. The shielding flange 320 makes the edge of the bottom plate 300 more smooth and neat, and forms a coordinated visual effect with the foot 400, enhancing the overall texture of the air conditioner indoor unit 100.

[0054] In combination with Figure 4 In order to support the bottom plate 300, the foot 400 exceeds the shielding flange 320, and in order to avoid scratching the bottom plate 300 during the movement of the air conditioner indoor unit 100, the distance from the lowest point of the bottom plate 300 to the end surface of the foot 400 is L1, and L1≥8mm, so that the bottom plate 300 can be effectively protected from direct collision or abrasion by external objects; in addition, the length of L1 should not be too long, but the specific length can be limited according to the structure and material. Generally, the length of the foot 400 is 10mm~20mm, so that the foot 400 has a certain structural strength and is not easy to break during movement, which helps to maintain the integrity and functionality of the foot 400 and ensures the stability of the air conditioner indoor unit 100.

[0055] In order to improve the structural strength of the bottom plate 300, the bottom surface 301 is provided with a structural rib 340, which defines an installation area 302 at each corner of the bottom surface 301 with the shielding flange 320, and the bottom foot 400 is arranged at the middle of the installation area 302; the arrangement of the structural rib 340 enhances the overall rigidity and stability of the bottom plate 300, and the arrangement of the installation area 302 makes the installation process of the bottom foot 400 more accurate and convenient, and the installation personnel can easily find the correct installation position and fix the bottom foot 400 at the predetermined position. This helps to reduce installation errors and time costs and improve overall installation efficiency. In addition to facilitating the positioning of the bottom foot 400 during installation, arranging the bottom foot 400 at the middle of the installation area 302 also enhances the overall aesthetics of the air conditioner indoor unit 100 in cooperation with the shielding flange 320. It should be noted that the lowest point of the bottom plate 300 at the bottom surface 301 can be on the structural rib 340 or on the shielding flange 320.

[0056] In combination Figure 1 Furthermore, the inner surface of the shielding flange 320 is also provided with a reinforcing rib 330, which significantly enhances the structural strength of the shielding flange 320 itself. The reinforcing rib 330 is arranged intermittently along the shielding flange 320, and multiple reinforcing ribs 330 support the shielding flange 320 like ribs, so that it can withstand greater external force without being easily deformed or damaged.

[0057] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application is included in the patent protection scope of the present application.
