Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a schematic structural diagram of an air conditioner external unit cleaning system 1 according to this embodiment. Fig. 2 is a schematic structural diagram of the condenser 11 and the storage tank 12 provided in this embodiment at a first view angle. Referring to fig. 1 and 2, the present embodiment provides an outdoor unit (not shown) including a casing and an outdoor unit cleaning system 1, where the outdoor unit cleaning system 1 is located inside the casing. The air conditioner outdoor unit cleaning system 1 includes a condenser 11, a storage tank 12, a blower 13, and a storage tank 12 located above the condenser 11, the storage tank 12 is provided with a drain port 121, and cleaning water in the storage tank 12 can flow out of the storage tank 12 through the drain port 121 and flow toward the condenser 11. After the blower 13 is activated, air may be blown towards the condenser 11.

It can be understood that the cleaning water discharged from the drain port 121 can more easily flow to the surface of the condenser 11 by gravity, improving the cleaning efficiency. The cleaning water flowing on the condenser 11 may soak the dust and foreign particles attached to the surface of the condenser 11 and cause the dust and foreign particles to become loose. Then, under the blowing action of the fan 13, the loosened dust and foreign particles can be more easily carried away by the wind blown by the fan 13, so that the dust and foreign particles on the surface of the condenser 11 can be cleaned more thoroughly, and the cleaning effect on the surface of the condenser 11 is effectively improved.

Generally, in practical applications, the fan 13 may be controlled to operate, the fan 13 blows air towards the condenser 11, and a part of dust and foreign particles on the surface of the condenser 11 may be blown away. Then, the drain port 121 is opened again, so that the cleaning water in the storage tank 12 flows onto the condenser 11, and the dust and foreign particles adhered to the condenser 11 relatively tightly are soaked, so that the dust and foreign particles become loosened. Then, the fan 13 is activated again to blow air toward the condenser 11, thereby bringing the loosened dust and foreign particles away from the condenser 11, and improving the cleaning effect of the surface of the condenser 11.

During normal discharge of the air-conditioning outdoor unit, the fan 13 rotates in the normal direction, air flows from the condenser 11 to the fan 13 (in the direction indicated by the arrow a in fig. 1), and the condenser 11 exchanges heat with the passing air. During cleaning of the condenser 11, the fan 13 is reversed, air flows from the fan 13 to the condenser 11 (in the direction indicated by arrow B in fig. 1), and the flowing air can carry away dust and foreign particles on the surface of the condenser 11.

Referring to fig. 2, in the present embodiment, a storage tank 12 is mounted on a ceiling wall of the condenser 11. In this way, the storage tank 12 can be positioned above the condenser 11 without using other supporting parts, so that the air conditioner outdoor unit cleaning system 1 is more compact and lower in cost.

In addition, since the storage box 12 is located above the condenser 11, the storage box 12 does not block the air blown out by the fan 13, and does not affect the air intake and air outtake of the condenser 11.

Referring to fig. 2, in the present embodiment, the drain port 121 is provided in the bottom wall of the storage tank 12 on the side close to the condenser 11. Thus, the cleaning water flowing out of the drain port 121 can directly flow to the condenser 11, and the cleaning water does not remain on the side wall of the storage tank 12, so that the waste of the cleaning water can be reduced. In addition, the bottom wall of the storage tank 12 is located closer to the condenser 11 than the top wall and other side walls of the storage tank 12, and thus the cleaning water flowing out of the drain port 121 in the bottom wall of the storage tank 12 can reach the condenser 11 more quickly, improving the cleaning efficiency.

Alternatively, the drain port 121 may be provided on the sidewall of the storage box 12.

It should be noted that, in the present embodiment, the bottom wall of the storage box 12 is located in the middle region of the thickness direction of the condenser 11, and the water outlet 121 is located in the middle region of the bottom wall of the storage box 12, so that the cleaning water flowing out from the water outlet 121 can flow to the inner side and the outer side of the condenser 11 more uniformly, and the dust and the foreign particles on the inner side and the outer side of the condenser 11 can be loosened by soaking, thereby facilitating the wind blown by the fan 13 to take away the dust and the foreign particles on the inner side and the outer side of the condenser 11 at the same time.

Referring to fig. 1, the area indicated by the arrow C in fig. 1 may be understood as an outer area of the condenser 11, and the area indicated by the arrow D in fig. 1 may be understood as an inner area of the condenser 11. Therefore, it can be inferred that the side of the condenser 11 close to the outside area (the area indicated by the arrow C) can be understood as the outside of the condenser 11, and the side of the condenser 11 close to the inside area (the area indicated by the arrow D) can be understood as the inside of the condenser 11.

Referring to fig. 2, in the present embodiment, the cleaning system 1 further includes a valve 14, the valve 14 is mounted on the storage box 12, and the valve 14 can open or close the drain opening 121. It will be appreciated that during storage of water in storage tank 12, valve 14 closes drain port 121. The valve 14 opens the drain 121 during the process of cleaning the condenser 11 of dust and foreign particles.

Generally, the valve 14 is a solenoid valve, so that the opening or closing of the valve 14 can be controlled by a controller, and the opening or closing process is simple and convenient.

It should be noted that, during normal operation of the air conditioner outdoor unit, the fan 13 draws air from the area where the condenser 11 is located, air flows from the condenser 11 to the fan 13, and the condenser 11 exchanges heat with the passing air, so that the temperature outside the condenser 11 is high. To this end, fig. 3 is a schematic structural diagram of the condenser 11 and the storage box 12 provided in the present embodiment at a second view angle, please refer to fig. 1 and 3, in the present embodiment, the fan 13 is located in an inner side area (an area indicated by an arrow D in fig. 1 and 3) of the condenser 11, and an overflow port 122 is disposed on a side of the storage box 12 facing away from the inner side area of the condenser 11. Therefore, the cleaning water flowing out of the overflow port 122 can flow to the outside of the condenser 11, and the cleaning water can cool the outside surface of the condenser 11, which is beneficial to heat dissipation of the condenser 11.

Referring to fig. 1 and 2, in the present embodiment, the number of the overflow ports 122 is plural, the plurality of overflow ports 122 are distributed at intervals along the length direction of the storage box 12, and the plurality of overflow ports 122 can simultaneously flow out the cleaning water, thereby effectively increasing the heat dissipation rate.

Referring to fig. 2, in the present embodiment, the overflow port 122 is provided in an upper edge region of the storage tank 12. When the cleaning water in the storage tank 12 is filled, the cleaning water flows out from the overflow port 122, and when the level of the cleaning water is lower than the overflow port 122, the cleaning water is stored in the storage tank 12 and does not flow out from the overflow port 122. Thus, the clean water in the storage tank 12 can be ensured not to flow out from the overflow port 122 completely, so that the clean water is always reserved in the storage tank 12, and the clean water can be ensured to flow out from the storage tank 12 after the water outlet 121 is opened.

Referring to fig. 2, in the present embodiment, the air conditioner outdoor unit cleaning system 1 further includes an indoor unit drain pipe 15, and condensed water generated by the air conditioner indoor unit can be discharged through the indoor unit drain pipe 15. The storage tank 12 is provided with a water inlet 123, and the water inlet 123 is communicated with the output end of the indoor unit drain pipe 15. Thus, the condensed water discharged from the air conditioner indoor unit can enter the storage tank 12 through the indoor unit drain pipe 15.

That is, the present embodiment uses the condensed water discharged from the air conditioner indoor unit as the clean water in the storage tank 12. Therefore, the condensed water discharged by the air conditioner indoor unit can be fully utilized, and the discharge of the condensed water is reduced. In addition, because the temperature of the condensed water discharged by the air conditioner internal unit is low, the condensed water flows to the outer surface of the condenser 11 from the overflow port 122, and then the cooling and heat dissipation effects on the condenser 11 are better.

Referring to fig. 2, in the present embodiment, water inlet 123 is provided in the upper half area of storage tank 12. Thus, the condensed water introduced from the water inlet 123 may be more easily deposited on the bottom of the storage tank 12 by gravity, facilitating the accumulated storage of the condensed water.

In addition, since water inlet 123 is located in the upper half area of storage tank 12, condensed water entering storage tank 12 is less likely to flow back into indoor unit drain pipe 15.

The embodiment also provides an air conditioner which comprises the air conditioner external unit and has all functions of the air conditioner external unit. It can be understood that the air conditioner can also comprise an air conditioner internal unit, the air conditioner internal unit is communicated with the air conditioner external unit, and the effect of adjusting the indoor temperature can be realized under the combined action of the air conditioner internal unit and the air conditioner external unit.

Fig. 4 is a block flow diagram of a cleaning method for an external unit of an air conditioner according to this embodiment. Referring to fig. 4, the present embodiment further provides a cleaning method of an external air conditioner, which can be operated by using the cleaning system 1 of the external air conditioner. Specifically, the cleaning method of the air conditioner outdoor unit comprises the following steps:

s31: the drain port 121 is opened.

S32: the fan 13 is controlled to blow air toward the condenser 11.

It is understood that the cleaning water in the storage tank 12 flows out of the storage tank 12 and flows toward the condenser 11 after the drain port 121 is opened. The cleaning water flowing on the condenser 11 may soak the dust and foreign particles attached to the surface of the condenser 11 and cause the dust and foreign particles to become loose. Then, after the fan 13 blows air towards the condenser 11, the loosened dust and foreign particles can be more easily carried away by the air blown by the fan 13, so that the dust and foreign particles on the surface of the condenser 11 can be cleaned more thoroughly, and the cleaning effect on the surface of the condenser 11 is effectively improved.

It should be noted that, in the present embodiment, opening the water outlet 121 may be understood as the controller controlling the aforementioned valve 14 to open, so that the water outlet 121 is in an open state.

Referring to fig. 4, before step S31, the method for cleaning an outdoor unit of an air conditioner further includes:

s30: the fan 13 is controlled to blow air towards the condenser 11 and after a first preset duration, the fan 13 is turned off.

That is, before the drain opening 121 is opened, the blower 13 is activated to blow away some dust and foreign particles stuck to the condenser 11, and the condenser 11 is pre-cleaned. Therefore, the consumption of some dust and impurity particles to the cleaning water is reduced, the subsequent cleaning water can be favorably used for fully soaking the dust and the impurity particles adhered to the surface of the condenser 11, and the cleaning effect is effectively improved.

In addition, after step S30 is completed, the fan 13 is in a closed state, so that the fan 13 does not blow air to the condenser 11 in the subsequent process that the cleaning water flows to the condenser 11, the cleaning water is not blown away from the condenser 11, and the flow process of the cleaning water is not affected by the air blown by the fan 13, so that the cleaning water can be ensured to fully soak the adhered dust and impurity particles.

Referring to fig. 4, after step S32, the method for cleaning an outdoor unit of an air conditioner further includes:

s33: after a second preset duration, the fan 13 is turned off.

It can be understood that after the condenser 11 is cleaned, the fan 13 is turned off, so that preparation can be made for the subsequent normal operation of the air conditioner external unit and the air exhausting operation of the fan 13.

The inventor researches and discovers that if the first preset time and the second preset time are long, the running time of the fan 13 is too long, electric energy is wasted, the use cost is increased, and meanwhile, the service life of the fan 13 is also shortened. If the first preset time period and the second preset time period are shorter, the blowing time of the fan 13 to the condenser 11 is shorter, which results in that the amount of dust and foreign particles carried away by the blown air is smaller, and the cleaning effect of the condenser 11 is not good. Therefore, it is necessary to limit the first preset time period and the second preset time period within a certain range.

Specifically, in the embodiment, the first preset time period is T1, and T1 is less than or equal to 15s and less than or equal to 300 s. The second preset time is T2, and T2 is more than or equal to 15s and less than or equal to 300 s. Therefore, electric energy can be saved, the service life of the fan 13 is prolonged, meanwhile, dust and foreign particles on the condenser 11 can be fully taken away by the air blown out by the fan 13, and the cleaning effect of the condenser 11 is improved.

Alternatively, the first preset time period T1 may be 15s, 100s, 300s, etc.

Alternatively, the second preset time period T2 may be 15s, 100s, 300s, etc.

In summary, the present embodiment provides an air conditioner outdoor unit cleaning system 1, an air conditioner outdoor unit cleaning method, an air conditioner outdoor unit and an air conditioner, which clean dust and foreign particles on the condenser 11 more thoroughly, and improve the cleaning effect of the condenser 11.
