Description

Technical Field

Background

[0002] In the prior art, the design of an evaporator pipeline layout of the air conditioner mainly to use s a back of a bottom shell to open an avoiding groove for a pipeline layout, so as to make the pipeline extend to a pipeline avoiding area at a lower part of the bottom shell, and the pipeline can be discharged from both sides of the air conditioner at the final installation. Such the design can prevent the pipeline layout from affecting an outer design of the air conditioner to some extent, and can protect the pipeline from collision damage during transportation. However, in the production assembly, the evaporator component must be integrally lifted up firstly when assembled to the bottom shell component, so that the pipeline passes longitudinally through the avoiding groove pipeline at the back of the bottom shell, and then the pipeline at the lower part of the bottom shell is hidden below the air conditioner. This largely limits the increase in production efficiency and increases the length of the pipeline, which is disadvantageous for production and cost control. Due to the design structure of the groove at the back of the bottom shell, the length direction of the bottom shell is cut off by the longitudinally generated pipeline layout groove, resulting in a problem of reduction in overall strength. Meanwhile, in the prior art, the left and right asymmetric screw connections and snap-fitting connections are adopted to fix the evaporator component, which causes the problem that the evaporator component shakes greatly and is easily broken and collides with the local structure when the whole machine is dropping.

[0045] In the present embodiment, the first end of the pipeline assembly is in communication with the evaporator assembly, the second end of the pipeline assembly is gradually extends from the first side of the first mounting surface of the base toward the second side of the base, and the second end of the pipeline assembly passes through the first mounting surface and the side where the second mounting surface is located and communicates with the outdoor unit. In this way, the pipeline assembly communicating with the outdoor unit is provided to arrange from the front of the base of the indoor unit, thereby avoiding the pipeline distribution mode in which the pipeline groove is provided in the back of the indoor unit in the prior art. The pipeline layout of the indoor unit is made more reasonable by adopting the pipeline layout of the pipe assembly in the present application. Furthermore, by means of the pipeline layout of the present application, it can be avoided that the pipeline groove is arranged at the back of the housing. Thus, the overall strength of the housing of the indoor unit is effectively improved, and the installation difficulty of the evaporator assembly is reduced, mechanized assembly of the indoor unit can be realized.

[0046] In the present embodiment, the left and right sides of the evaporator component are respectively provided with a angle-shaped frame and a pressing plate with screws and hooks, and the pipeline is designed to be lifted up and bent forwardly and upwardly, so as to cooperate with a fixation of a motor seat and a pipeline layout groove structure on the base, so that the evaporator component can be directly assembled from the front surface without reversing the whole machine. This arrangement not only improves the assembly efficiency of the whole machine, but also facilitates the maintenance work of disassembly and assembly after sale. The front edge of the base raises for avoiding a pipeline layout, thereby achieving unobstructed assembly and disassembly of the bottom shell component and satisfying the requirement of convenient assembly and disassembly of the bottom shell component.

[0047] As shown in Fig. 7, the motor base component is firstly assembled to the base component, and then the pre-assembled evaporator component is assembled to the base component. The left side of the evaporator component is designed with an angle-shaped frame structure (the angle-shaped frame is fitted together with the evaporator by two screws), the front end of the angle-shaped frame is designed with a hook and a screw column structure cooperated with the base, the back portion of the the angle-shaped frame is provided with a screw column for fixing the bottom shell, and the peripheral structure is a protective pipe structure 227 for protecting the U-shaped pipe of the evaporator and a screw column 228. The right side of the evaporator component is designed with a right pressing plate structure (the right pressing plate is connected to the evaporator by an edge evaporator buckle), the front of the right pressing plate is designed with a hook structure cooperated with the base, the back portion of the right pressing plate is provided with a screw hole cooperated with the motor base, and the pipeline is designed to be raised and bent forwardly and upwardly, and then directly extended to the front of the evaporator component, then bent toward the bottom of the evaporator. Hold the two sides of the evaporator component by hands while assembling, the hooks on the left and right sides are quickly inserted into the left and right hook mounting holes designed on the base to complete preset positioning and mounting, and at this time, the inner side surface of the hook cooperates with the platform surface of the base hook, and this surface is parallel to the bottom surface of the base, thereby ensuring that the mounted evaporator component is smoothly mounted on the base. As shown in Fig. 2, A and B in the figure are evaporator buckles of the right pressing plate.

[0048] The evaporator component is mounted on the base component to realize the pre-positioning and preliminary assembly of the evaporator component, at this time, the evaporator component can be preliminarily stabilized on the base, and the fixing screw holes of the left angle-shaped frame and the base are aligned. Furthermore, a fixing screw hole of the right pressing plate and a fixing screw column hole of the right pressing plate at the top of the motor base are aligned, and then two fixing screws can be used to directly fix the evaporator component on the base component to complete fixing and assembling of the evaporator component. The whole assembly process only needs to be hanged from the front of the base component, and the whole assembly operation can be completed by bolting the screws, which is simple and quick to assemble.

[0049] After the fixing of the evaporator component and the base is completed, according to the pipeline layout shown in Fig. 5, only a micro-corrective on deformed pipelines is required, so that the pipeline can be arranged along the pipeline layout groove structure at the top of the motor base, then passes downward through the front of the motor base, and extends along the preset pipeline layout avoiding notched of the base to front edge lower portion of the base, and finally, bends to left and extends to the bottom protruding the protective plate of a front edge of the base . In this case, the protective plate structure disposed on the base is protruded and lifted, so that the space at the bottom of the front edge of the base facilitates the pipeline layout. The dismantling process of the bottom shell component always slides along the inclined surfaces generated by the base front edge lifting for the pipeline layout and the base front edge lifting and the protruding protective plate structure can protect the air-liquid pipeline well, so that the bottom shell component can be prevented from colliding during pulling and loading. The disassembly operation of the bottom shell component is facilitated, the production assembly efficiency is improved, and the disassembly of the bottom shell component can also be realized when the user cleans the bottom shell component after sale. In the schematic diagram of the bottom shell component and the base component, the bottom shell component and the bottom shell fixing screw column of the angle-shaped frame and the bottom shell fixing screw column of the right pressing plate are respectively fastened by screws, and since the bottom shell component is slid into the base by the guide rail and then is fastened integrally with the base by screws. At this time, in the completely fastened structure, the front part of the evaporator component and the bottom shell component are merely connected, which also enables the evaporator component to have a screw symmetrically fastened to the hanging hook at four diagonal corners respectively, so that the evaporator component is firmly connected to the base as a whole, thereby avoiding a shaking collision in the fall, and improving the stability of the structure.

[0050] With the air conditioner of the present mechanism, modularization and integration of the structure design of the air conditioner are realized. However, the conventional evaporator back pipeline layout and the left and right asymmetric evaporator fixing structure are used, which not only consumes time of the reversal of the machine in the assembly, but also has poor stability of the overall structure and is less convenient for the removing and maintenance work after sale.
