[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] This application provides the following technical solutions:

[0042] An air conditioner evaporator cleaning structure includes an installation frame 1 and a guard plate group. The installation frame 1 is a frame structure. A filter positioning structure is arranged inside the installation frame 1. With reference to the use state of the installation frame 1, a filter disassembly opening for removing the filter is reserved at the top of the installation frame 1. The horizontal side is the evaporator side 101, and the other side is the frequency converter side 102. The guard plate group includes two guard plates 2, which are detachably connected to the installation frame 1. Each guard plate 2 is provided with a shielding structure 21, which can shield the frequency converter side 102 of the installation frame 1.

[0043] The cleaning structure has two states, one of which is the daily use state. Figure 1 and Figure 2 The following is the daily state. The other state is the cleaning state when used in conjunction with the guard plate assembly, that is, the state when the evaporator is cleaned, such as Figure 4 and Figure 5 As shown, in this state, the guard plate 2 is used in combination with the mounting frame 1, and the evaporator can be flushed with a water gun.

[0044] On the basis of the above implementation scheme, the installation frame 1 includes a main frame 11 of a rectangular frame structure. The main frame 11 forms a rectangular frame structure, which includes two parallel side panels 111, a top panel 112 and a bottom panel 113. The top panel 112 is located between the top ends of the side panels 111, and a disassembly opening is reserved thereon; the bottom panel 113 is located between the bottom ends of the side panels 111. Connecting rings are respectively provided on the side panels 111, and the connecting rings are arranged on the opposite sides of the two side panels 111. The connecting rings are semi-annular structures, and connecting holes are provided on the annular bodies. The top panel 112 is connected to the upper cover 12 by threads, and the upper cover 12 can close the disassembly opening; a downwardly protruding boss 121 is provided on the upper cover 12 corresponding to the disassembly opening.

[0045] The area surrounded by the main frame 11 is the space for placing the filter in daily use. When cleaning is required, the screws on the upper cover 12 are removed to expose the disassembly opening on the top plate 112. Figure 4 As shown, the filter is then pulled out from the disassembly port, and the filter is cleaned or replaced. At the same time, the position of the disassembly port can be used as a water gun nozzle to spray water to clean the evaporator. When the cleaning is completed, the filter and the upper cover 12 can be reinstalled.

[0046] Based on the above implementation, the filter screen positioning structure includes a lower positioning structure and an upper positioning structure. The lower positioning structure is arranged on the bottom plate 113 and is a slot structure corresponding to the filter screen; the upper positioning structure is arranged on the lower side of the boss 121 of the upper cover 12 and is a positioning plate corresponding to the slot structure. Figure 1 As shown, a vertical flange is provided on the edge of the bottom plate 113 to form a lower positioning structure. Figure 3 It is a schematic diagram of the bottom angle of the upper cover 12, and two long strip-shaped plates are arranged on the cover to form an upper positioning structure corresponding to the evaporator clamping.

[0047] On the basis of the above embodiment, a reinforcement frame 13 is further provided on one side of the main frame 11 located on the evaporator side 101. The reinforcement frame 13 includes a plurality of reinforcement rods 131 arranged in a crisscross pattern. Through holes are distributed on the rod bodies of the reinforcement rods 131. A reinforcement plate 132 is provided at the bottom of the reinforcement frame 131. The reinforcement plate 132 is a strip-shaped plate body and is fixedly connected to the bottom plate 113.

[0048] The side plate 111 is provided with a clamping plate 14 extending toward the edge of the evaporator side 101. Figure 2 As shown, the clamping plate 14 is covered on both sides of the reinforcement frame 13, and a clamping interface is provided at the lower part of the clamping plate 14. The clamping plate 14 can further fix the reinforcement frame 13, and can also be clamped with the structural frame at the evaporator position by means of the clamping interface at the lower part of the clamping plate 14, so as to facilitate the positioning of the installation frame.

[0049] On the basis of the above implementation scheme, after the filter is removed and before the evaporator is flushed, the guard plate group can be placed on the installation frame 1 to protect the frequency converter box on the other side and prevent the frequency converter from being splashed by water. Figure 6 The shielding structure 21 of the guard plate 2 includes a main shield plate 211 and a side shield plate 212. The main shield plate 211 is vertically extended, and the side shield plate 212 is at least arranged on one side of the main shield plate 211. This solution adopts a structural form of setting two guard plates 2, and the two guard plates 2 are mirror-symmetrical structures.

[0050] The guard plate 2 is provided with a hanging structure 22, through which the mounting frame 1 can be hung. The hanging structure 22 includes an upper hanging member 221 and a lower hanging member 222. The upper hanging member 221 is provided on the upper side of the main shielding plate 211 and can be hung with the disassembly opening on the main frame 1; the lower hanging member 222 is provided corresponding to the reinforcing plate 132 and can be hung on the reinforcing plate 132. In addition, a drainage structure 23 is provided between the main shielding plate 211 and the lower hanging member 222, and the drainage structure 23 can drain toward the outside of the mounting frame 1.

[0051] See also Figure 5 and Figure 6 The main baffle plate 211 is a vertical plate body, and the side baffle plates 212 are respectively arranged on both sides of the main baffle plate 211. The side baffle plate 212 facing the outer end of one lateral side of the main frame 11 is wider, and the other side can be relatively narrower. An upper hanging member 221 is arranged on one side of the upper end of the main baffle plate 211, which is a horizontal plate structure and can be placed on the disassembly port. At the same time, a horizontal flange is arranged on the other side of the upper edge of the main baffle plate 211, which has a certain degree of shielding effect on water splashing. The lower hanging member 222 is arranged corresponding to the reinforcing plate 132 and can be placed on the upper edge of the reinforcing plate 132. The drainage structure 23 is an inclined plate structure, the lower horizontal end of which is arranged toward the evaporator side 101, and the high horizontal end is connected to the lower edge of the main baffle plate 211, and the drainage structure 23 is provided with a bayonet corresponding to the reinforcing rod 131.

[0052] When flushing the evaporator, the guard plate 2 can effectively prevent the inverter from being affected, because the water flow is sprayed toward the evaporator, and some water droplets will splash toward the inverter. The guard plate 2 can block this part of the splashing water, and at the same time, the water is guided into the water pan or drain groove under the evaporator through the drainage structure 23.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
