DETAILED DESCRIPTION

[0022] 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 utility model. 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.

[0023] This specific embodiment is a central air conditioning descaling device, and its structural schematic diagram is as follows Figure 1 , Figure 4 As shown, it includes a bottom box 1, a cleaning table 2, a support beam 3 and a water tank 4. The bottom box 1 is arranged below the cleaning table 2, and the support beam 3 is horizontally fixedly installed above the cleaning table 2. A screw is rotatably installed inside the inner side of the support beam 3, and a movable slider 17 is installed on the external thread of the screw. The movable slider 17 fits the bottom of the support beam 3, and the bottom of the movable slider 17 is fixedly connected to a telescopic cylinder 18; the telescopic cylinder 18 is vertically arranged, and the end away from the movable slider 17 is fixedly connected to the upper surface of the water tank 4.

[0024] Reference Figure 1 , Figure 3 A nozzle 14 is installed at the bottom of the water tank 4, and a mounting frame 11 is fixedly installed on the side wall of the water tank 4. The mounting frame 11 is vertically arranged, and a driving screw 15 is rotatably installed inside. A driving box 12 is rotatably installed on the external thread of the driving screw 15. A cleaning wheel 13 is rotatably installed on the outer wall of the driving box 12. The driving box 12 has a first motor connected to the cleaning wheel 13 inside. A lifting groove for the driving screw 15 to be embedded is vertically opened on the mounting frame 11. A lifting block is protruded on the outer wall of the driving box 12. The lifting block is embedded in the lifting groove and is threadedly connected to the driving screw 15. A second motor is fixed above the mounting frame 11, and the second motor is connected to the driving screw 15. Through the forward and reverse rotation of the screw, the water tank 4 has the force to move repeatedly, and the telescopic cylinder 18 extends to drive the water tank 4 to descend in height, so that the nozzle 14 is closer to the air conditioning components.

[0025] Reference Figure 2, drainage holes 6 are provided on the inner wall of the cleaning table 2, and the drainage holes 6 are arranged in an array. The interior of the bottom box 1 is a hollow structure, and a diverter plate 5 is provided in the center. The diverter plate 5 is a triangular structure and gradually tilts toward the two side walls of the bottom box 1. Through holes 16 are provided on the two side walls of the bottom box 1. A fixing column 10 is vertically installed in the center of the inner wall of the cleaning table 2, and a clamping cylinder 8 is vertically installed on the inner side of the fixing column 10, and a pressure strip 9 is connected to the telescopic end of the clamping cylinder 8.

[0026] Working principle: When in use, first place the panels, filters, impellers and other components removed from the central air conditioner on the inner side of the cleaning table 2, then connect the water tank 4 to the water source through a hose. After water enters the hose, the nozzle 14 at the bottom of the water tank 4 can discharge water to rinse the air-conditioning components on the upper surface of the cleaning table 2. The screw inside the support beam 3 rotates, and the screw is driven by the third motor installed on the outer wall of the cleaning table 2, and then the slider 17 is moved to slide along the bottom thread transmission of the support beam 3, driving the water tank 4 to move. Through the forward and reverse rotation of the screw, the water tank 4 has the force to move repeatedly, and the telescopic cylinder 18 extends to drive the water tank 4 to descend in height, so that the nozzle 14 is closer to the air-conditioning components, and the flushing effect is better. At the same time, as the water tank 4 descends, the mounting frame 11 is driven to descend synchronously. At this time, the second motor on the mounting frame 11 starts, driving the driving screw 15 to rotate, and the screw of the driving screw 15 is screwed to the bottom of the supporting beam 3. The driving box 12 connected with the groove descends, and the driving box 12 has a first motor inside. The first motor drives the cleaning wheel 13 to rotate. After the water tank 4 descends, not only can the nozzle 14 be close to the air-conditioning component, but also the cleaning wheel 13 can be close to the air-conditioning component to roll and brush the dirt and dust on the air-conditioning component. It is practical. The driving screw 15 and the driving box 12 are driven to transmit the cleaning wheel 13 so that the cleaning wheel 13 can be raised and lowered. When facing air-conditioning components of different heights, it can be adjusted, and the descaling effect is good. When flushing the filter, the filter can be placed under the pressure strip 9, and the clamping cylinder 8 is extended to drive the pressure block to press the filter, so that the filter has a clamping force, which is convenient for subsequent flushing and keeps stable. The sewage generated during the descaling process flows into the bottom box 1 through the drainage hole 6. Since the bottom box 1 is provided with a diverter plate 5, the sewage is concentrated and discharged from the through hole 16, and the hose can be connected for discharge.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
