Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, and in particular to an automatic cleaning device for an outdoor unit of an air conditioner. Background Art

[0002] Most household air conditioners are split type air conditioners, which include an outdoor unit and an indoor unit. The outdoor unit is a condenser in cooling state. There is an opening on the back of the outdoor unit, where several heat dissipation fins are exposed. When dust, hair and other objects accumulate on the surface of the heat dissipation fins, the cooling effect of the air conditioner will be seriously affected, resulting in a decrease in cooling efficiency. For this reason, people manually clean the heat dissipation fins of the outdoor unit regularly to avoid a decrease in the condensation effect of the outdoor unit, thereby ensuring the cooling effect of the air conditioner. This method is very labor-intensive and material-intensive, and requires the use of an external water source for flushing, which is not environmentally friendly. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art and to provide an automatic cleaning device for an air conditioner outdoor unit which is environmentally friendly and can improve the working efficiency of the air conditioner.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] The automatic cleaning device for the outdoor unit of an air conditioner comprises: a mounting assembly mounted on the outdoor unit of the air conditioner; a spray assembly mounted on the mounting assembly, on which a plurality of nozzles facing the heat dissipation fins of the outdoor unit of the air conditioner are arranged; a water storage tank for collecting condensed water discharged from the indoor unit of the air conditioner; a water supply device connecting the water storage tank and the spray assembly, for transferring the water in the water storage tank to the spray assembly; a water level control component arranged in the water storage tank, electrically connected to the water supply device, for controlling the opening and closing of the water supply device. The automatic cleaning device for the outdoor unit of an air conditioner of the above structure uses the mounting assembly to fix the spray assembly so that the nozzle faces the heat dissipation fins of the outdoor unit of the air conditioner, collects the condensed water discharged from the indoor unit of the air conditioner through the water storage tank, and after the water level rises to trigger the water level control component, the water supply device transfers the water in the water storage tank to the spray assembly, and then rinses the heat dissipation fins of the outdoor unit of the air conditioner; the automatic cleaning device for the outdoor unit of an air conditioner does not require manual operation, saves time and labor, and does not require an external water source, which is both environmentally friendly and saves water resources.

[0006] Preferably, the mounting assembly includes at least one mounting bar, and the two ends of the mounting bar are detachably mounted on the opposite sides of the back opening of the air conditioner outdoor unit. The mounting assembly has a very simple structure, and the two ends of the mounting bar are equivalent to a beam column after being fixed. The spray assembly is mounted on the mounting bar, which can reduce the production cost of the automatic cleaning device for the air conditioner outdoor unit.

[0007] Preferably, in some embodiments of the present invention, the mounting assembly includes two mounting bars vertically distributed in parallel, the spray assembly includes at least one pipeline transversely connected to the two mounting bars, a plurality of nozzles are spaced apart along the length direction of the pipeline and connected to the pipeline, and the upper end of the mounting bar is provided with a first connector that can be mounted on the upper side of the back opening of the air conditioner outdoor unit and a second connector that can be mounted on the lower side of the back opening of the air conditioner outdoor unit. A roughly H-shaped bracket structure is formed between the two mounting bars and the pipeline, which is very light and stable and reliable to install.

[0008] Preferably, the mounting strip is provided with a plurality of vertical waist-shaped holes at intervals along its length direction, and the pipeline is fixed to two adjacent vertical waist-shaped holes by a clamp. According to the needs of use, the height position of the pipeline can be adjusted to adjust the flushing effect on the heat dissipation fins of the air conditioner outdoor unit.

When fixing the mounting strip to the air conditioner outdoor unit, it is only necessary to insert the second hook portion into the lower side of the back opening of the air conditioner outdoor unit, and then slide the first hook portion so that the first hook portion is inserted into the upper side of the back opening of the air conditioner outdoor unit, and then lock the first hook portion and the second hook portion in turn, so as to achieve quick installation and disassembly with a simple structure, and can be adapted to air conditioners of different specifications, with strong versatility.

[0010] Preferably, the pipeline is serpentine-shaped along its length direction to form a plurality of bent tube portions away from the heat dissipation fins of the air conditioner outdoor unit, and each bent tube portion is provided with a nozzle. The bent tube portion can increase the distance between the nozzle and the heat dissipation fins of the air conditioner outdoor unit, increase the spraying range of the nozzle, and avoid that some heat dissipation fins cannot be cleaned. Moreover, the bent tube portion is formed by bending the pipeline and does not require additional assembly, thereby improving the efficiency of production and assembly.

[0011] Preferably, the nozzle is an atomizing nozzle, which can adjust the atomization degree of the spray according to the actual use situation, increase the spraying area, save water, and at the same time, utilize the characteristics of easy evaporation and fast heat absorption of the condensed water in the atomized state to improve the heat dissipation performance of the air conditioner outdoor unit, thereby achieving the purpose of improving the air conditioning refrigeration effect.
