Specifically, the air conditioner 100 is a device that adjusts the temperature of indoor air through a refrigeration cycle. The air conditioner 100 may include an air conditioner window unit, a split type air conditioner. The outdoor unit 10 of the air conditioner 100 may be installed outdoors to exchange heat with the indoor unit 20 through a compressor, a refrigerant pipe 30, and the like. The outdoor unit 10 may include an outdoor heat exchanger 12 and an outdoor fan, and the outdoor heat exchanger 12 may be a condenser. The outdoor water tank 11 of the outdoor unit 10 may be disposed below the condenser. The section of the outdoor water tank 11 can be a concave shape with an upward opening, and the outdoor water tank 11 can collect the condensed water flowing down from the condenser.

The indoor unit 20 can be connected to the outdoor unit 10 through the refrigerant pipe 30, the spray head 41 of the spray assembly 40 can be inserted into the outer casing of the outdoor unit 10, and part of the spray head 41 can protrude out of the outer surface of the outer casing of the outdoor unit 10.

The water tube 42 may be a copper tube or a hose.

In cold environment, the air conditioner 100 is operated to generate heat, condensed water is generated in the outdoor unit 10, and the condensed water collected in the outdoor water tank 11 is pressurized by the spray pump 44 and then sprayed from the spray head 41 along the water pipe 42. The portion of the water pipe 42 thermally connected to the refrigerant pipe 30 may be a portion of the water pipe 42 near the spray head 41 thermally connected to the refrigerant pipe 30. A thermal connection is understood to be a connection which can transfer heat. The refrigerant pipe 30 can transmit heat to the water pipe 42 to prevent the water pipe 42 from being frozen, so that the spray head 41 can smoothly spray condensed water to the outside of the outdoor unit 10.

The spray pump 44 may be provided inside the indoor unit 20, and the influence of cold environment on the spray pump 44 and the water pipe 42 can be further prevented.

Referring to fig. 1 to 3, in some embodiments, the indoor unit 20 has an indoor water tank 21, the indoor water tank 21 is used for collecting indoor condensed water, the water pipe 42 includes a first pipe 421 and a second pipe 422, one end of the first pipe 421 extends into the outdoor water tank 11, the other end extends into the indoor water tank 21, one end of the second pipe 422 is connected to the spray head 41, the other end extends into the indoor water tank 21, the first pipe 421 is provided with a first suction pump 43, the spray pump 44 is provided on the second pipe 422, and the first pipe 421 and/or the second pipe 422 are/is partially thermally connected to the refrigerant pipe 30.

In this way, when the air conditioner 100 performs a cooling operation, condensed water generated in the indoor unit 20 enters the indoor water tank 21, is compressed by the spray pump 44 through the second pipe 422, and is atomized and discharged from the spray head 41.

Specifically, the indoor unit 20 may be provided with an inner fan and an indoor heat exchanger 22 spaced from the inner fan, and the indoor heat exchanger may be an evaporator or a condenser, etc. The indoor water tank 21 may be positioned below the indoor heat exchanger 22, and the indoor water tank 21 may have a concave cross-section and a width greater than that of the indoor heat exchanger 22. The indoor water tank 21 collects condensed water flowing down the indoor heat exchanger 22.

The first pipe 421 of the water pipe 42 can connect the outdoor water tank 11 and the indoor water tank 21, when the air conditioner 100 enters the heating mode, the condensed water in the outdoor water tank 11 gradually increases, the first water pump 43 is started, the condensed water can be pumped from the outdoor water tank 11 to the indoor water tank 21, and then the condensed water in the indoor water tank 21 can be atomized to the outdoor through the high-pressure injection of the atomizing head 41 by the compression of the atomizing pump 44.

The spray pump 44 may be disposed on the second pipe 422 located inside the indoor unit 20, and the spray pump 44 may be disposed near the inner fan. Part of the first pipe 421 may be connected to the refrigerant pipe 30 to conduct heat of the refrigerant pipe 30, part of the second pipe 422 may be connected to the refrigerant pipe 30 to conduct heat of the refrigerant pipe 30, or both parts of the first pipe 421 and the second pipe 422 may be connected to the refrigerant pipe 30 to conduct heat of the refrigerant pipe 30. Preferably, the second pipe 422 connected to the spray pump 44 may be a copper pipe, or a section of the second pipe 422 connected to the spray head 41 may be a copper pipe.

Referring to fig. 1-3, in some embodiments, the first tube 421 and/or the second tube 422 are partially in contact with the refrigerant tube 30.

Thus, the first pipe 421 and the second pipe 422 are in contact with the refrigerant pipe 30, and the path of the refrigerant pipe 30 for conducting heat to the first pipe 421 and the second pipe 422 is short, so that the heat conducting speed is high.

Specifically, a portion of the first pipe 421 located in the outdoor unit 10 may contact the refrigerant pipe 30, and a portion of the second pipe 422 located in the outdoor unit 10 and near the spray header 41 may contact the refrigerant pipe 30. The heat of the refrigerant in the refrigerant pipe 30 can be conducted through the contact between the refrigerant pipe 30 and the first pipe 421 and the second pipe 422.

Referring to fig. 1-3, in some embodiments, the spray assembly 40 further includes a heat conducting member connecting the coolant pipe 30 and the spray head 41.

Thus, the heat conducting member is connected with the refrigerant pipe 30 and the atomizing head 41 at the same time, and in a cold environment, the heat conducting member can provide heat conduction for the atomizing head 41 by utilizing the heat of the refrigerant in the refrigerant pipe 30, so that the atomizing head 41 is prevented from being blocked and frozen in a low-temperature environment.

Specifically, the heat conducting member may be a pipe, an element, or a device that can be connected to the refrigerant pipe 30 and the spray head 41. The heat conducting member may be connected to the refrigerant pipe 30 and the spray head 41 at the same time, or connected to the refrigerant pipe 30 and the spray head 41 separately. The heat conducting member can conduct the heat transferred from the refrigerant pipe 30 to the spray head 41, and heat the spray head 41 in a low temperature environment.

Referring to fig. 1-3, in some embodiments, the heat conducting member includes a heat conducting pipe 45, the heat conducting pipe 45 is disposed on the spray head 41, and a first end 451 of the heat conducting pipe 45 extends into the cooling medium pipe 30, and the heat conducting pipe 45 is introduced into the cooling medium.

In this way, heat pipe 45 passing through the refrigerant can transfer the heat of the refrigerant to spray head 41, and heat pipe 45 is provided in spray head 41, and it is not necessary to separately form a hole in air conditioner 100 to connect heat pipe 45.

Specifically, the heat pipe 45 may be a capillary tube, and the heat pipe 45 may be fixed to the spray head 41 by a fixing means such as welding. The first end 451 of the heat pipe 45 may be an end close to the outdoor unit 10, the first end 451 of the heat pipe 45 may extend into the cooling medium pipe 30, and the heat pipe 45 may communicate with a portion of the cooling medium pipe 30 close to the spray head 41, so as to shorten the length of the heat pipe 45, reduce the throttling effect, reduce the temperature of the heat pipe 45, and prevent insufficient heat transfer. The heat pipe 45 can conduct the heat of the refrigerant to the spray head 41.

Referring to fig. 1-3, in some embodiments, the heat pipe 45 is wound around the spray head 41.

In this way, the heat transfer pipe 45 is wound around the atomizing head 41, so that the contact area between the heat transfer pipe 45 and the atomizing head 41 is increased, the heat transfer area is increased, and the atomizing head 41 can be heated in all directions.

Specifically, the atomizing head 41 may be configured to protrude cylindrically from the sidewall of the indoor unit 20. The heat pipe 45 is wound around the spray head 41 such that the heat pipe 45 is wound along the outer surface of the spray head 41 and then fixedly connected to the spray head 41 by welding.

Referring to fig. 1-3, in some embodiments, the spray head 41 has a spray outlet 411, and the second end 452 of the heat pipe 45 extends to the periphery of the spray outlet 411.

In this way, because under the low temperature environment, spray head 41 sprays and can remain the water droplet at atomising mouth 411, and the freezing of remaining water droplet can cause the jam, and extend the second end 452 of heat pipe 45 to the week side of atomising mouth 411, can be better for spray head 41 heating prevent that the water droplet around atomising mouth 411 freezes and influences spray head 41 and spray.

Specifically, the spray opening 411 of the spray head 41 may be disposed on the spray head 41 away from the center of the outer side surface of the outdoor unit 10, and the spray opening 411 may have a circular shape. The spray opening 411 can communicate the inner space of the spray head 41 to the outside, and the spray head 41 can spray the condensed water in the second pipe 422 along the spray opening 411. The second end 452 of the heat pipe 45 can be the end distal from the first end 451. Second end 452 may surround spray opening 411, and the end of second end 452 may be disposed around one circumferential side of spray opening 411.

Referring to fig. 1-3, in some embodiments, the second end 452 of the heat pipe 45 is located below the spray opening 411.

Thus, in a low-temperature environment, the freezing of water droplets remaining in spray opening 411 may cause spray opening 411 to be clogged, and the frozen water droplets are located under spray opening 411 by gravity. The second end 452 of the heat pipe 45 is located below the spray opening 411 to better prevent the water drops at the spray opening 411 from freezing.

Specifically, the second end 452 of the heat pipe 45 may be located below the spray opening 411, and the second end 452 may be disposed in parallel with a diameter direction of the spray opening 411.

Referring to fig. 1 to 3, in some embodiments, the indoor unit 20 has an indoor water tank 21, the indoor water tank 21 is used for collecting indoor condensed water, and a spray assembly 23 is disposed in the indoor unit 20, and the spray assembly 23 is used for extracting the indoor condensed water and spraying the indoor condensed water onto an indoor heat exchanger 22 of the indoor unit 20.

In this way, when the indoor unit 20 is provided with the shower assembly 23 so that the air conditioner 100 enters the cooling mode, the condensed water in the indoor water tank 21 can be consumed in a shower humidification manner.

Specifically, the indoor water tank 21 of the indoor unit 20 may collect condensed water formed by the indoor heat exchanger 22. The indoor water tank 21 can be arranged below the heat exchanger, the spraying assembly 23 can be arranged above the indoor heat exchanger 22, the spraying assembly 23 can spray condensed water in the indoor water tank 21 to the indoor heat exchanger 22, and the condensed water forms water mist through heat of the indoor heat exchanger 22 to humidify the indoor.

Referring to fig. 1-3, in some embodiments, the spray assembly 23 includes a water pumping pipe 231, a second water pumping pump 232 and a spray member 233, the water pumping pipe 231 communicates the indoor water tank 21 and the spray member 233, the second water pumping pump 232 is disposed on the water pumping pipe 231, and the spray member 233 is disposed on the top of the indoor heat exchanger 22.

Therefore, the spraying assembly 23 compresses the condensed water in the water pumping pipe 231 through the water pumping pump and then sprays the condensed water to the indoor heat exchanger 22 through the spraying piece 233, so that the condensed water in the indoor water tank 21 can be consumed, the heat exchanger efficiency can be improved, and the problem of condensed water discharge can be solved.

Specifically, the pumping pipe 231 of the spraying assembly 23 may be a hose, and one end of the pumping pipe 231 may extend into the indoor water tank 21, and the other end may extend into the spraying member 233. The spray 233 may be a humidification water tank, and the bottom of the humidification water tank may be formed with a through hole facing the indoor heat exchanger 22. A second suction pump 232 may be mounted on the suction pipe 231 near the bottom of the indoor heat exchanger 22. When the air conditioner 100 enters the cooling mode, after the indoor water tank 21 collects a certain amount of condensed water, the second water pump 232 may be started to operate to pump the condensed water in the indoor water tank 21 to the spraying member 233, and spray the condensed water from the spraying member 233 to the indoor heat exchanger 22.

Referring to fig. 1-3, in some embodiments, the air conditioner 100 further includes a controller 70 connected to the spray pump 44, wherein the controller 70 is configured to control the spray pump 44 to operate when the water level in the outdoor water tank 11 is higher than a first water level.

In this way, the controller 70 of the air conditioner 100 can control the operation of the spray pump 44 according to the water level of the outdoor water tank 11, thereby reducing the time required for the operation of the spray pump 44 and making the process of the air conditioner 100 for consuming the condensed water more intelligent.

Specifically, the controller 70 may be a control switch, the water level in the outdoor water tank 11 may gradually increase as the air conditioner 100 heats, and the first water level of the outdoor water tank 11 may be a water level in the outdoor water tank 11 up to more than half of the depth of the outdoor water tank 11. The controller 70 may detect and control the operation of the spray pump 44 by the first control switch 111 disposed at the first water level of the outdoor water tank 11 to spray and discharge the condensed water in the outdoor water tank 11, thereby preventing the condensed water from leaking.

In certain embodiments, the controller 70 may also control the first suction pump 43 and the spray pump 44. When the air conditioner 100 enters the heating mode, the condensed water in the outdoor water tank 11 gradually increases, and when the condensed water reaches the first water level, the controller 70 may control the first water pump 43 to start, pump the condensed water from the outdoor water tank 11 to the indoor water tank 21, and then control the spray pump 44 to start, and spray and atomize the condensed water in the indoor water tank 21 to the outside at a high pressure.

Referring to fig. 1 to 3, in some embodiments, the controller 70 is further configured to control the air conditioner 100 to be stopped when the water level in the outdoor water tank 11 reaches a second water level, which is higher than the first water level.

In this way, when the water level exceeds the first water level and reaches the second water level, the controller 70 controls the air conditioner 100 to stop, which can prevent the condensed water caused by the continuous operation of the air conditioner 100 from continuously increasing and overflowing the outdoor water tank 11, thereby improving the safety of the air conditioner 100.

Specifically, the second water level may be higher than the first water level inside the outdoor sink 11 and near the top of the outdoor sink 11. When the air conditioner 100 is operated for a long time and has a large power, such that the condensed water in the outdoor water tank 11 is gradually increased after the spray is discharged, and reaches the second water level after exceeding the first water level, the controller 70 may control the air conditioner 100 to stop and issue an alarm by controlling the second control switch 112 located at the second water level of the outdoor water tank 11.

The shutdown of the air conditioner 100 may be a function of stopping the air conditioner 100 from heating and retaining other functions that do not generate condensed water, or may be a function of stopping the operation of the entire air conditioner 100 and stopping all functions.

It should be noted that, when the water level in the indoor water tank 21 exceeds the first water level, the controller 70 may control the operation of the water pump by controlling the third control switch 211 arranged at the first water level of the indoor water tank 21; when the water level in the indoor water tank 21 exceeds the second water level, the air conditioner 100 may be controlled to be stopped by controlling the fourth control switch 212 provided at the second water level of the indoor water tank 21.

Referring to fig. 1 to 3, in some embodiments, the outdoor unit 10 is provided with a raindrop detector 50, the raindrop detector 50 detects outdoor rainfall, and the controller 70 is configured to control the spray pump 44 to be in a shutdown state when the outdoor rainfall is greater than a rainfall threshold.

Thus, when the outdoor unit 10 is in a rain condition and the rainfall is large, the outdoor unit 10 is in rain, and the rain water drops from the outdoor unit 10, and when the condensed water of the outdoor unit 10 overflows, the dropped condensed water is negligible compared to the rain water. Therefore, the controller 70 may control the spray pump 44 to stop working without spraying or pumping out the condensed water in the outdoor water tank 11, thereby reducing the use of the spray pump 44, saving electricity, increasing the service life of the spray pump, and further increasing the service life of the air conditioner 100.

Specifically, the raindrop detector 50 may be disposed inside a top wall of the outdoor unit 10, the raindrop detector 50 may detect an outdoor rainfall, and the rainfall threshold may be a numerical value at which the rainfall reaches a preset rainfall. When the outdoor rainfall detected by the raindrop detector 50 reaches the rainfall threshold, the controller 70 may control the spray pump 44 to stop operating. The water overflowing from the outdoor water tank 11 can directly flow down and drip out of the room.

The indoor unit 20 may further include a humidity detector 60, and the humidity detector 60 may detect the indoor humidity, and when the indoor humidity is greater than a humidity threshold, the controller 70 may control the spray assembly 23 to stop working without humidification.
