Description

Technical Field

[0001] The utility model relates to the field of air conditioner outdoor units, in particular to an automatic dust cleaning device for an air conditioner outdoor unit. Background Technique

[0002] The air conditioner outdoor unit is an important part of the air conditioner system. Its main function is to dissipate the heat absorbed by the indoor unit into the outdoor environment, so as to achieve the indoor cooling or heating effect. The cooling capacity and energy efficiency ratio of the air conditioner mainly depend on the operating efficiency of the condenser arranged inside the air conditioner outdoor unit. In order to increase the contact area between the condenser and the outside air and enable the heat to be dissipated into the surrounding environment more efficiently, multiple groups of heat dissipation fins are arranged on the outer wall of the condenser.

[0003] The heat dissipation fins are thin metal sheets evenly and neatly arranged on the condenser pipes. These thin metal sheets are in close contact with the pipes and play the role of increasing the heat exchange area of the pipes. In order to ensure that the heat dissipation fins can be in direct contact with the outside air without being blocked, so as to conduct heat exchange more effectively, generally the heat dissipation fins are exposed outside, which will cause a large amount of dust to adhere to the outside of the heat dissipation fins. If not processed for a long time, it will reduce its heat dissipation efficiency, thereby reducing the working efficiency of the condenser.

[0004] In the prior art, when some users clean the heat dissipation fins of the air conditioner outdoor unit, they directly clean the heat dissipation fins by manually using tools such as brushes, hair dryers or compressed air spray guns to remove the dust and debris on the surface. The manual cleaning method has too low efficiency and is too time-consuming and laborious. Especially when operating in some harsh environments such as steel mills, the harsh environment will accelerate the speed of dust adhesion to the heat dissipation fins, which will increase the frequency of manual cleaning by users and is too troublesome.

The upper surface of the left end of the steel pipe 12 is fixedly connected to the front surface of the electrical box 4 through an air pipe.

[0036] Refer to Figure 3 - Figure 4 、 Figure 6 , The front surface of the connecting plate 63 is provided with through holes 65 and there are multiple groups. The provided through holes 65 can ensure that air can be ejected smoothly. A brush 64 is fixedly connected to the front surface of the connecting plate 63.

The rubber material has a certain elasticity, which ensures the stability when the connecting plate 63 is installed on the inner wall of the dust cleaning shell 62, and can also improve the disassembly speed of the connecting plate 63, improving the convenience.

[0037] Refer to Figure 2 - Figure 3 、 Figure 5, a plugging rod 92 is slidably connected through the top end of the right surface of the moving plate 91. A groove 11 is formed on the right surface of the bottom end of the mounting frame 1. The left surface of the plugging rod 92 contacts the inner wall of the groove 11. A spring 93 is sleeved on the outer wall of the plugging rod 92. The spring 93 has a certain elasticity and always pulls the plugging rod 92 to move leftward through its own elasticity to ensure the stability of its limit. One end of the spring 93 is fixedly connected to the right surface of the top end of the moving plate 91, and the other end of the spring 93 is fixedly connected to the left surface of the plugging rod 92.

[0038] Working principle: When in use, in some factories, such as a steelmaking factory, compressed air can be led to the main compressed air source pipe beside the outdoor unit of the air conditioner nearby through a pipe body made of DN15 steel. An oil-water separator 7 is installed on the main compressed air source pipe through a union. The oil-water separator 7 and the pressure stabilizing tank 5 are connected by a D steel pipe 12 through a union. A branch pipe needs to be branched out on this section of the pipeline and is equipped with a DN15 manual ball valve. The compressed air is connected to the two-position five-way pneumatic cylinder control solenoid valve in the electrical box 4 through a PU air pipe to provide power for the action of the cylinder 8. The air outlet of the pressure stabilizing tank 5 is connected to the inlet of the jet solenoid valve in the electrical box 4 through a DN15 PU air pipe. The outlet of the jet solenoid valve is connected to the air source distribution pipe 3 on the mounting frame 1 through a DN15 PU air pipe. Four PU pneumatic quick connectors are equipped on the air source distribution pipe 3 and are connected to four PU pneumatic quick connectors on the dust cleaning shell 62 through a telescopic pipe 61. The cylinder 8 is fixed to the middle of the top end of the mounting frame 1 through bolts, and the dust cleaning shell 62 is fixed to the slider of the cylinder 8 through screws.

[0039] In terms of electricity, the Siemens LOGO controller inside the electrical box 4 can be programmed with a control program to control the start and stop of the jet solenoid valve, realize the on-off of the air source provided by the pressure stabilizing tank 5 to the dust cleaning shell 62, and synchronously control the two-position five-way pneumatic cylinder control solenoid valve to realize the reciprocating movement of the cylinder 8.

[0040] Before the automatic dust cleaning device of the outdoor unit of the air conditioner works, it is necessary to set the dust cleaning time interval and the reciprocating times of the cylinder 8 in the Siemens LOGO controller in the electrical box 4 according to the working environment, and adjust the running speed of the device on the cylinder 8. When the device is running, the dust cleaning shell 62 reciprocates with the slider on the cylinder 8. At the same time, the jet solenoid valve is opened, and the compressed air in the pressure stabilizing tank 5 is sprayed out through the air source distribution pipe 3 on the mounting frame 1, the telescopic pipe 61, and the air slots on the dust cleaning shell 62, and cooperates with the brush 64 arranged on the inner wall of the dust cleaning shell 62 to clean the dust on the fins of the outdoor unit of the air conditioner, eliminating the need for manual cleaning and improving the convenience.

[0041] When the brush 64 needs to be replaced after a period of use, simply pull the connecting plate 63, and the clamping block 66 will move accordingly and be deformed by extrusion to disengage from the inner wall of the limiting groove 67, so that the brush 64 can be disassembled. During installation, insert the connecting plate 63 into the inner wall of the dust cleaning shell 62. During the insertion process, the clamping block 66 will be deformed by extrusion until the clamping block 66 overlaps with the limiting groove 67, and the clamping block 66 will be reset by its own elasticity and clamped on the inner wall of the limiting groove 67 to limit the connecting plate 63.

[0042] It is also possible to adjust the position of the moving plate 91 to adjust the depth of the brush 64 extending into the heat dissipation fins provided on the air conditioner outdoor unit 2. Just pull the plugging rod 92, and the plugging rod 92 will stretch the spring 93 until the plugging rod 92 completely disengages from the inner wall of the groove 11. At this time, the position of the dust cleaning component can be adjusted through the moving plate 91. After the adjustment is completed, release the plugging rod 92, and the spring 93 will pull the plugging rod 92 to move reversely by its own elasticity for resetting to limit the moving plate 91.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
