With reference to fig. 1 to 5, an embodiment of the present disclosure provides an air conditioner, including a refrigerant circulation loop sequentially connected to a compressor 10, an outdoor heat exchanger 11, a throttling component 12, and an indoor heat exchanger 13, and further including a spraying system, a heat exchange coil 15, and a check valve 18, where the spraying system includes a water tank 30, and the spraying system is used to spray the outdoor heat exchanger 11; the heat exchange coil 15 is positioned in the water tank 30, a first end of the heat exchange coil 15 is connected to a first pipeline between the compressor 10 and the outdoor heat exchanger 11 through a first connecting pipe 16, and a second end of the heat exchange coil 15 is connected to a second pipeline between the indoor heat exchanger 13 and the throttling component 12 through a second connecting pipe 17; the check valve 18 is disposed on the heat exchanging coil 15, and the communication direction of the check valve 18 is from the compressor 10 to the throttling component 12.

In the embodiment of the present disclosure, the spraying system is used to spray the outdoor heat exchanger 11. The conducting direction of the check valve 18 describes the direction of the refrigerant in the heat exchange coil 15. When the air conditioner operates in the cooling mode, on the one hand, the temperature of the spray water is lower than that of the outdoor heat exchanger 11, the spray water can exchange heat with the outdoor heat exchanger 11 to reduce the temperature of the outdoor heat exchanger 11, on the other hand, the spray system sprays the outdoor heat exchanger 11 to enable the surface of the outdoor heat exchanger 11 to be in a moistening state, the spray water absorbs a large amount of heat from the outdoor heat exchanger 11 to be evaporated into a gaseous state, the outdoor heat exchanger 11 is cooled, and the operation of an outdoor fan can accelerate the process. When the air conditioner heats, the refrigerant is reversely circulated, the liquid refrigerant absorbs heat through the outdoor heat exchanger 11 to become a gaseous refrigerant, the gaseous refrigerant becomes a high-temperature and high-pressure gaseous refrigerant through the compressor 10, then the gaseous refrigerant passes through the indoor heat exchanger 13, the heat is transferred to the indoor space under the action of the indoor fan, the temperature of the gaseous refrigerant is reduced, then the gaseous refrigerant becomes the liquid refrigerant through the throttling component 12 and enters the outdoor heat exchanger 11, and the liquid refrigerant is repeatedly circulated in such a way, the temperature of the outdoor heat exchanger 11 is lower, and water vapor in the air is easily condensed on the outdoor heat exchanger 11 to form a frost layer. The pipeline between the compressor 10 and the outdoor heat exchanger 11 is a first pipeline, and a first end of the heat exchange coil 15 is connected to the first pipeline through a first connecting pipe 16. The pipeline between the indoor heat exchanger 13 and the throttling component 12 is a second pipeline, and the second end of the heat exchange coil 15 is connected to the second pipeline through a second connecting pipe 17. When the air conditioner is in the heating mode, the refrigerant in the first pipeline is a high-temperature high-pressure gaseous refrigerant, and the temperature and the pressure of the refrigerant in the second pipeline are less than those of the refrigerant in the first pipeline, so that the refrigerant in the circulating system moves from the first end of the heat exchange coil 15 to the second end of the heat exchange coil 15 under the action of pressure difference, and the high-temperature refrigerant flows through the heat exchange coil 15 and heats the water tank 30. By using the air conditioner provided by the embodiment of the disclosure, the water in the water tank 30 is heated by the heat exchange coil 15 to make the temperature of the water higher than the surface temperature of the outdoor heat exchanger 11, the water pump provides spraying pressure, and the spraying system sprays hot water to the outdoor heat exchanger 11 to make the frost layer of the outdoor heat exchanger 11 melt quickly, so that the heating of the air conditioner can be continuously performed. The one-way valve 18 is arranged to enable the refrigerant in the heat exchange coil 15 to have a determined flow direction, so that the circulation effect of the refrigerant in the heat exchange coil 15 is improved, further, the heating effect of the heat exchange coil 15 on the water in the water tank 30 is improved, and the defrosting effect of the air conditioner is also improved. By using the spraying system for the outdoor heat exchanger 11 provided by the embodiment of the disclosure, the spraying system can spray the outdoor heat exchanger 11 to assist the air conditioner to refrigerate when the air conditioner refrigerates, and can spray hot water to the outdoor heat exchanger 11 to defrost when the air conditioner needs defrosting, so that the refrigerating and defrosting efficiency of the air conditioner is improved, and the user experience is improved.

Optionally, the air conditioner further includes an electromagnetic valve 14, and the electromagnetic valve 14 is disposed on the heat exchanging coil 15 and is configured to control a flow rate of the refrigerant flowing through the heat exchanging coil 15. In the embodiment of the present disclosure, controlling the flow rate of the heat exchange coil 15 includes controlling the on/off state of the refrigerant pipeline of the heat exchange coil 15, and when the flow rate of the heat exchange coil 15 is 0, the electromagnetic valve 14 is closed, and the refrigerant pipeline of the heat exchange coil 15 is in the off state. The solenoid valve 14 is provided to open the solenoid valve 14 to allow the refrigerant in the heat exchanging coil 15 to form a passage, thereby heating the water in the water tank 30 as required. When the air conditioner is in a cooling mode or the temperature of water in the water tank 30 reaches a defrosting requirement, the refrigerant passage of the heat exchange coil 15 can be cut off by closing the electromagnetic valve 14. The opening degree of the solenoid valve 14 is adjustable so that the opening degree of the solenoid valve 14 can be determined according to the difference between the temperature of the water in the water tank 30 and the temperature of the water required for defrosting. When the opening degree of the electromagnetic valve 14 is large, the flow rate of the refrigerant in the heat exchange coil 15 is large, and the heat exchange efficiency of the heat exchange coil 15 is high, so that the temperature of the water in the water tank 30 is quickly increased. When the opening degree of the electromagnetic valve 14 is small, the flow rate of the refrigerant in the heat exchange coil 15 is small, and the heat exchange efficiency of the heat exchange coil 15 is low, so that the temperature of the water in the water tank 30 is slowly increased. The heat exchange efficiency is the heat of heat exchange of the heat exchange coil 15 with the water in the water tank 30 per unit time. The opening of the electromagnetic valve 14 can be adjusted, so that the air conditioner can control the temperature of the water tank 30 more flexibly and conveniently. Alternatively, when the difference between the temperature of the water in the water tank 30 and the temperature of the water required for defrosting is large, the solenoid valve 14 may be controlled to be opened by a large opening degree; when the difference between the temperature of the water in the water tank 30 and the temperature of the water required for defrosting is small, the solenoid valve 14 may be controlled to be opened by a small opening degree. Alternatively, the air conditioner determines the next defrosting start time according to the outdoor environment temperature and humidity, and determines the opening degree of the electromagnetic valve 14 according to the difference between the current defrosting start time and the next defrosting start time. Therefore, the temperature of the water tank 30 can be improved by the heat exchange coil 15, the heating and defrosting requirements of the air conditioner can be met, and the heat loss caused by heat exchange between the water tank 30 and the outside when the temperature of the water tank 30 is increased to the temperature required by defrosting in advance can be avoided.

Alternatively, the solenoid valve 14 is provided to the first connection pipe 16, and the check valve 18 is provided to the second connection pipe 17. The pipeline between the compressor 10 and the outdoor heat exchanger 11 is a first pipeline, and a first end of the heat exchange coil 15 is connected to the first pipeline through a first connecting pipe 16. The pipeline between the indoor heat exchanger 13 and the throttling component 12 is a second pipeline, and the second end of the heat exchange coil 15 is connected to the second pipeline through a second connecting pipe 17. The refrigerant in the first pipeline is a high-temperature high-pressure gaseous refrigerant, and the temperature and pressure of the refrigerant in the second pipeline are lower than those of the refrigerant in the first pipeline, so that the refrigerant in the circulating system moves from the first end of the heat exchange coil 15 to the second section of the heat exchange coil 15 under the action of pressure difference. The solenoid valve 14 is arranged in the first connecting pipe 16, which is also arranged at the inlet end of the heat exchanging coil 15. The check valve 18 is arranged on the second connecting pipe 17, and is also arranged at the liquid outlet end of the heat exchange coil. The liquid inlet end and the liquid outlet end are only used for explaining the flowing direction of the refrigerant, and do not mean that the refrigerant flowing through the liquid inlet end and the liquid outlet end is liquid refrigerant. When the electromagnetic valve 14 is disposed at the liquid inlet end of the heat exchanging coil 15, the flow rate of the refrigerant flowing through the heat exchanging coil 15 and the on/off of the refrigerant passage in the heat exchanging coil 15 can be better controlled. The check valve 18 is disposed at the liquid outlet end of the heat exchanging coil 15, so as to better prevent refrigerant pressure fluctuation from causing the refrigerant to flow from the second end of the heat exchanging coil 15 to the first end of the heat exchanging coil 15.

Optionally, the air conditioner further includes a first control module, and the first control module is configured to control the solenoid valve 14 to be closed when the air conditioner operates in the cooling mode, and control the solenoid valve 14 to be opened when the air conditioner operates in the heating mode. When the air conditioner refrigerates, the outdoor heat exchanger 11 is sprayed with low-temperature or normal-temperature water without increasing the temperature of water in the water tank 30; when the air conditioner heats, the temperature of the outdoor heat exchanger 11 is gradually reduced along with the heating operation, and the possibility of frosting of the outdoor heat exchanger 11 is increased, so that the electromagnetic valve 14 is opened to heat the water in the water tank 30 when the air conditioner enters the heating mode, and thus, when the air conditioner defrosts, the heated water can be sprayed at the first time, and thus, the defrosting efficiency can be improved. In the embodiment of the present disclosure, the hot water, the cold water, and the normal temperature water are hot, cold, and normal temperature compared to the outdoor heat exchanger 11 and the outdoor ambient temperature, and no comparison is made between the three. For example, when the air conditioner is defrosted, the surface temperature of the outdoor heat exchanger 11 is lower than zero, and the outdoor environment temperature is also lower than zero, and the hot water refers to water having a temperature higher than the surface temperature of the outdoor heat exchanger 11 or higher than the outdoor environment temperature. Specifically, when the air conditioner is refrigerating, the outdoor environment temperature is thirty degrees centigrade, the surface temperature of the outdoor heat exchanger 11 is forty-five degrees centigrade, and the temperature of the normal-temperature water in the spray water tank 30 is thirty degrees centigrade; when the air conditioner is defrosted, the outdoor environment temperature is below zero, the surface temperature of the outdoor heat exchanger 11 is below zero, and the temperature of the spray hot water is two degrees centigrade. Alternatively, when the air conditioner is heating, the solenoid valve 14 is opened to increase the temperature of the water tank 30 to the first preset temperature. Setting the heating control target allows for better control of the temperature of the water in the water tank 30. Optionally, the first preset temperature is two degrees celsius. The higher the temperature of the water in the water tank 30 is, the better the defrosting effect is, but the higher the amount of heat required by the heating means to raise the temperature of the water tank 30 is, the more heat the water tank 30 loses by heat transfer. When defrosting the outdoor heat exchanger 11, the water in the water tank 30 at two degrees centigrade can ensure a better defrosting effect, and the temperature of the water in the water tank 30 does not need to be increased by much heat.

Optionally, the first control module is further configured to open the solenoid valve 14 to increase the temperature of the water in the water tank 30 to a first preset temperature when the air conditioner is in the run defrost mode. In a use scene with low defrosting frequency, the heat is wasted because the water temperature is kept at the first preset temperature for a long time, therefore, when the running state of the air conditioner is in a defrosting mode, the electromagnetic valve 14 is opened to increase the temperature of the water tank 30 to the first preset temperature, although the temperature of the water tank 30 has certain hysteresis for the defrosting requirement of the air conditioner, the defrosting requirement of the air conditioner can be met with low energy consumption.

Optionally, the first control module is further configured to control the solenoid valve 14 to close when the air conditioner is operating in the defrost mode. When the air conditioner needs defrosting, the surface of the outdoor heat exchanger 11 is covered with a frost layer and does not exchange heat well with the external environment. In this case, the heating effect of the air conditioner is also affected. Therefore, the electromagnetic valve 14 is closed when the air conditioner operates in the defrosting mode, so that the flow rate of the refrigerant in the refrigerant circulation loop can be increased, the influence of defrosting of the air conditioner on the heating effect of the indoor environment is reduced as much as possible, and the use experience of a user is improved.

Optionally, the spraying system further comprises a water pump and a spraying water pipe 20, wherein the water pump is arranged on the water tank 30; the spray pipe 20 is communicated with the water pump, the spray pipe 20 comprises a spray box 31, the spray box 31 is provided with a plurality of spray holes 32 with adjustable apertures, and the water tank 30 is provided with a water filling port and a water outlet.

Optionally, the spraying system further comprises an aperture adjusting device for adjusting the water outlet aperture of the spraying water pipe 20. The outlet aperture is the cross-sectional area of the water flow passing through the spray holes 32 during spraying. When the air conditioner sprays the outdoor heat exchanger 11, the flow, the water outlet pressure and the spraying distance of the spray water can be changed by changing the aperture of the spraying holes 32, when the water supply pressure of the spray water pipe is fixed, the flow, the water outlet pressure and the spraying distance of the spray water can be changed by changing the aperture of the spraying holes 32, and further, the flow, the water outlet pressure and the spraying distance of the spray water can be adjusted by adjusting the aperture of the spraying holes 32.

Optionally, the aperture adjusting device includes an aperture adjusting sheet 33 slidably connected to the bottom of the spraying box 31, wherein the aperture adjusting sheet 33 is provided with a plurality of adjusting holes 34 corresponding to the plurality of spraying holes 32, the plurality of spraying holes 32 are communicated with the plurality of adjusting holes 34 when the aperture adjusting sheet 33 is located at the first position, and the aperture adjusting sheet 33 blocks the plurality of spraying holes 32 when the aperture adjusting sheet 33 is located at the second position. The shape of the aperture adjusting sheet 33 corresponds to the shape of the bottom of the spraying box 31, and the aperture adjusting sheet 33 is tightly attached to the bottom of the spraying box 31, so that the part of the aperture adjusting sheet 33, which is contacted with the spraying and the bottom, can not be penetrated by water. When the plurality of spray holes 32 and the plurality of adjustment holes 34 are communicated, the spray water in the spray box 31 can be sprayed to the outside through the spray holes 32 and the adjustment holes 34. When the aperture adjusting sheet 33 blocks the spraying holes 32, the solid parts between the plurality of adjusting holes 34 of the aperture adjusting sheet 33 block the plurality of spraying holes 32, and the spraying box 31 cannot spray. The solid portion of the aperture regulating blade 33 refers to a portion between the plurality of regulating holes 34 of the aperture regulating blade, and the solid is a concept opposite to the hollowness of the regulating holes 34. The aperture adjustment sheet 33 is slidably connected to the bottom of the spray box and is continuously slidable between a first position and a second position. Thus, when the aperture adjusting sheet 33 slides from the first position to the second position, the aperture of the water outlet is continuously reduced because the shielding part of the aperture adjusting sheet 33 for the spray holes 32 is gradually increased; when the aperture adjusting sheet 33 slides from the second position to the first position, the aperture of the water outlet is continuously increased because the shielding part of the aperture adjusting sheet 33 to the spray hole 32 is gradually reduced. Therefore, the size of the water outlet aperture can be conveniently changed by changing the position of the aperture adjusting sheet 33 relative to the bottom of the spraying box 31, so that the spraying flow, the spraying pressure and the spraying distance are changed, and further, the air conditioner is more accurately controlled to spray.

Optionally, the aperture adjustment device further comprises a driving motor 35 fixed to the shower box 31 for driving the aperture adjustment sheet 33 to continuously move between the first position and the second position. The position of the aperture adjusting sheet 33 at the bottom of the shower box 31 can be conveniently changed by arranging a motor. The driving motor 35 is arranged to make the air conditioner more convenient to control the spraying.

Optionally, the air conditioner further includes a second control module configured to control the water pump to operate at a first power when the air conditioner operates in the cooling mode, and to control the water pump to operate at a second power when the air conditioner operates in the defrosting mode, wherein the first power is less than or equal to the second power. When the air conditioner operates in a refrigeration mode, the heat quantity taken away by the heat exchange between the spray water and the surface of the outdoor heat exchanger 11 is less, and the heat quantity absorbed by the spray water through evaporation from the surface of the outdoor heat exchanger 11 is more, so that too much spray water is not needed for the refrigeration of the air conditioner. When the air conditioner operates in the defrosting mode, the heat required for removing the frost layer is provided by the heat exchange between the sprayed water and the surface of the outdoor heat exchanger 11, and therefore, when the air conditioner operates in the defrosting mode, more water needs to be sprayed to the outdoor heat exchanger 11. In order to increase the defrosting speed, it is also necessary to shower the outdoor heat exchanger 11 at a high speed. The second control module is arranged, so that the air conditioner can spray the outdoor heat exchanger 11 at a proper speed in a refrigeration mode and a defrosting mode, water required by spraying can be saved, and meanwhile, the accurate control of the air conditioner on spraying can be improved.

Optionally, the air conditioner further includes a first water pan disposed below the outdoor heat exchanger 11 and provided with a first water drainage port, wherein the water tank 30 is further provided with a water return port, and the first water drainage port is connected to the water return port. When the air conditioner outdoor heat exchanger 11 is in heating operation, the outdoor heat exchanger 11 can generate condensed water when the temperature of the outdoor heat exchanger 11 is below the condensation point temperature; when the air conditioner is used for refrigerating, the spraying system sprays the outdoor heat exchanger 11, one part of water is evaporated, and the other part of water flows to the lower part of the outdoor heat exchanger 11 along the outdoor heat exchanger 11; when the air conditioner defrosts, the spray system performs spray defrosting of the outdoor heat exchanger 11, and water generated by defrosting and spray water flow along the outdoor heat exchanger 11 to the lower side of the outdoor heat exchanger 11. If the water is not utilized, the waste of water resources is caused. Therefore, a first water receiving tray is arranged below the outdoor heat exchanger 11, a first water discharging opening is formed in the water receiving tray, and water generated by condensation, spray water and defrosting water can return to the water tank 30 through the first water discharging opening and a water returning opening of the water tank 30 through the water receiving tray. Therefore, the utilization rate of water resources is improved.

Optionally, the air conditioner further comprises a ball float valve provided at a water filling port of the water tank 30, the water filling port being connected to a municipal water supply network, the ball float valve maintaining the water level of the water tank 30 at a first preset water level. Both the spraying when the air conditioner operates in the cooling mode and the spraying when the air conditioner operates in the defrosting mode cause a reduction in the spray water in the water tank 30 due to evaporation or contamination of water, and thus the spray water in the water tank 30 needs to be replenished. The water filling port of the water tank 30 is connected to a municipal water supply network, so that automatic water supply of the air conditioner can be conveniently realized. The water filling port sets up the ball-cock assembly, and the ball-cock assembly includes valve, connecting rod and floater, and its height also changes along with the change of water tank 30 water level, and when the water in water tank 30 reached first predetermined water level, the floater floated to first height, and the drive connecting rod rotates, and the valve is closed under the lever action of connecting rod. The provision of a float valve allows the cistern 30 to be automatically filled and maintained at a first predetermined level.

Optionally, the height of the water return port is higher than a first preset water level. When the air conditioner sprays the outdoor heat exchanger, the water level in the water tank 30 is lowered, the ball float valve is opened to keep the water level of the water tank 30 at the first preset water level, and the water sprayed on the outdoor heat exchanger 11 returns to the water tank 30 through the water return port. The height of the water return port is higher than the first preset water level, so that automatic water feeding and circulating water return of the water tank 30 can be better matched.
