[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0043] Combination Figure 1-6 As shown, an embodiment of the present disclosure provides an outdoor unit, including a housing 1 , an outdoor heat exchanger 11 , a water storage device 2 and a spraying device 3 .

[0044] like Figure 1 and Figure 2 As shown, the water storage device 2 is arranged in the shell 1, the water storage device 2 defines a water storage chamber 21, and is provided with a water outlet channel 22 connected to the water storage chamber 21, and the water outlet channel 22 is arranged toward the outdoor heat exchanger 11; the spraying device 3 is arranged in the water outlet channel 22, and is used to spray the water in the water outlet channel 22 toward the outdoor heat exchanger 11.

[0045] With the outdoor unit provided by the embodiment of the present disclosure, the condensed water generated by the outdoor unit enters the water storage device 2, and the spraying device 3 sprays the condensed water from the water outlet channel 22 of the water storage device 2 to the outdoor heat exchanger 11, which can cool the outdoor heat exchanger 11 and improve the heat exchange efficiency of the outdoor unit. The outdoor unit can also be cleaned to play a cleaning role. The setting of the spraying device 3 can spray the condensed water to the outdoor heat exchanger 11 over a relatively large area. Compared with the free dripping of the condensed water to the outdoor unit, the cooling area is increased, the cooling effect is improved, and the noise generated by the dripping of the condensed water can be avoided. In addition, the sprayed condensed water droplets are dispersed and small in size, which causes less damage to the outdoor unit.

[0046] Alternatively, if Figure 3 and Figure 4As shown, the spraying device 3 includes a rotating member 31, which is arranged in the water outlet channel 22, is arranged in the direction of the outdoor heat exchanger 11, and can rotate relative to the water outlet channel 22 to drive the water in the water outlet channel 22 to spray toward the outdoor heat exchanger 11; a driving member, which is connected to the rotating member 31 to drive the rotating member 31 to rotate; a fixed member 32, one end of which is sleeved on the rotating member 31, and the other end is fixedly connected to the inner wall of the water outlet channel 22 to support the rotating member 31 in the water outlet channel 22; wherein the rotating member 31 can rotate relative to the fixed member 32.

[0047] When the condensed water in the water storage device 2 is stored above the water outlet channel 22, the driving member drives the rotating member 31 to start rotating, and the condensed water flows outward from the water outlet channel 22. During the rotation of the rotating member 31, centrifugal force is generated, and the condensed water is thrown out of the water outlet channel 22 under the drive of the rotating member 31, and sprayed toward the outdoor heat exchanger 11. The rotation of the rotating member 31 makes the condensed water spread over a larger area when it sprays out of the water outlet channel 22, and the area when it is scattered to the outdoor heat exchanger 11 is larger, which increases the heat exchange area of ​​the outdoor heat exchanger 11, accelerates the cooling rate of the outdoor heat exchanger 11, and achieves a better cooling effect.

[0048] The setting of the fixed part 32 fixes the rotating part 31, so that the rotating part 31 is relatively fixed in the direction toward the outdoor heat exchanger 11, and the rotating part 31 can rotate relative to the fixed part 32, so that when the rotating part 31 rotates to spray condensed water, a better spraying effect is achieved.

[0049] The fixing member 32 includes a base and a plurality of fixing parts, the plurality of fixing parts are evenly distributed around the base, the base is sleeved on the rotating shaft, and the rotating shaft can rotate relative to the base. Each fixing part is fixedly connected to the inner wall of the water outlet channel 22 at one end and fixedly connected to the base at the other end, and the plurality of fixing parts and the base together support the rotating member 31 in the water outlet channel 22.

[0050] The driving member can be a motor, which is connected to the rotating member 31. When condensed water needs to be sprayed, the motor is turned on, and the motor drives the rotating member 31 to start rotating. The condensed water flows outward from the water outlet channel 22. During the rotation of the rotating member 31, centrifugal force is generated, and the condensed water is thrown out of the water outlet channel 22 and sprayed toward the outdoor heat exchanger 11.

[0051] Alternatively, if Figure 3 and Figure 4As shown, the rotating member 31 includes: a rotating shaft 34, which is arranged in the water outlet channel 22 and extends along the length direction of the water outlet channel 22, wherein one end of the fixed member 32 is sleeved on the end of the rotating shaft 34 close to the water storage chamber 21, and the rotating shaft 34 can rotate relative to the fixed member 32; a rotating part 33, which is connected to the rotating shaft 34, is arranged at one end of the rotating shaft 34 close to the outdoor heat exchanger 11, and extends in a direction close to the inner wall of the water outlet channel 22; wherein, when the driving member drives the rotating member 31 to rotate, the rotating shaft 34 drives the rotating part 33 to rotate together, and the rotating part 33 drives the water in the water outlet channel 22 to spray toward the outdoor heat exchanger 11.

[0052] When it is necessary to spray condensed water, the condensed water enters the water outlet channel 22 from the water storage chamber 21, and the driving member drives the rotating shaft 34 to rotate, and the rotating shaft 34 drives the rotating part 33 to rotate. During the rotation of the rotating part 33, centrifugal force is generated, and the condensed water is thrown out of the water outlet channel 22 under the drive of the rotating part 33 to be sprayed toward the outdoor heat exchanger 11.

[0053] Alternatively, if Figure 4 As shown, the rotating portion 33 includes a plurality of rotating blades 331 , and the plurality of rotating blades 331 are evenly distributed around the rotating shaft 34 .

[0054] The above embodiment mentioned that the rotating member 31 is arranged at one end of the rotating shaft 34 close to the outdoor heat exchanger 11, and can spray condensed water to the outdoor heat exchanger 11 to a greater extent when rotating. The plurality of rotating blades 331 are provided to provide greater centrifugal force for the condensed water, and the number of blades increases, the total area of ​​the blades increases, and more condensed water can be driven to rotate, and then thrown out of the water outlet channel 22 and sprayed to the surface of the outdoor heat exchanger 11. The plurality of rotating blades 331 are evenly distributed on the rotating shaft 34 in the circumferential direction, and can provide a more balanced centrifugal force when rotating, so that the effect of the rotating member 31 spraying condensed water when rotating is more uniform. The centrifugal force balance can also make the force on the entire spraying device 3 balanced when the driving member drives the rotating member 31, avoiding uneven force causing wear between the rotating member 31 and the fixed member 32, ensuring the smooth operation of the spraying device 3, so that the spraying device 3 can also work normally under long-term use, and increase the service life of the spraying device 3.

[0055] Alternatively, if Figure 5 As shown, the water storage device 2 includes a first water tank 23 and a second water tank 24. The first water tank 23 is arranged on the shell 1 and is provided with a condensed water inlet 25. There are multiple second water tanks 24, which are arranged at the bottom of the first water tank 23 and are connected to the first water tank 23. The water outlet channel 22 is arranged on the side of the second water tank 24 facing the outdoor heat exchanger 11. The condensed water passes through the condensed water inlet 25, the first water tank 23 and the second water tank 24 in sequence and flows out from the water outlet channel 22.

[0056] A plurality of second water reservoirs 24 are arranged at the bottom of the first water reservoir 23. The condensed water generated by the indoor unit enters the first water reservoir 23 and flows from the first water reservoir 23 to the second water reservoir 24. The height difference between the first water reservoir 23 and the second water reservoir 24 allows the condensed water to do work due to gravity when flowing downward, generating gravitational potential energy, which can provide power for the condensed water to flow out of the water outlet channel 22, thereby reducing the energy consumption of the driving part. An opening is arranged at the top of the first water reservoir 23. In addition to the condensed water flowing out of the indoor unit of the air conditioner, the first water reservoir 23 can also receive water sources brought by natural weather such as rainwater or dew, providing more water sources for the water storage device 2 for the spraying device 3 to spray water to the outdoor heat exchanger 11, so as to cool the outdoor heat exchanger 11.

[0057] Optionally, a plurality of second water reservoirs 24 are evenly distributed at the bottom of the first water reservoir 23 .

[0058] The first water reservoir 23 is in the shape of a rectangular parallelepiped, and multiple second water reservoirs 24 are arranged at the bottom of the first water reservoir 23. The length and width of the first water reservoir 23 are greater than the length and width of the second water reservoir 24. The projections of the multiple second water reservoirs 24 in the direction of the first water reservoir 23 fall inside the projection of the first water reservoir 23. When the condensed water enters the second water reservoir 24 from the first water reservoir 23, the volume changes from large to small, which will increase the impact force of the condensed water when entering the second water reservoir 24, increase the flow rate of the condensed water, and provide power for the condensed water to flow out of the water outlet channel 22, thereby reducing the energy consumption of the driving component.

[0059] Alternatively, if Figure 5 and Figure 6 As shown, each second water storage tank 24 is provided with a plurality of water outlet channels 22 .

[0060] There are multiple spraying devices 3, so that when the condensed water is sprayed to the outdoor unit through the spraying devices 3, the spraying area of ​​the condensed water is larger and the amount of sprayed water is larger, so as to achieve a better cooling effect on the outdoor heat exchanger 11, thereby better improving the heat exchange efficiency of the outdoor unit. Multiple spraying devices 3 are all arranged toward one side of the outdoor heat exchanger 11, and the angles of each spraying device 3 can be the same or different. When the angles are the same, the condensed water can be sprayed more evenly. When the angles are different, the condensed water can be sprayed at multiple angles on the outdoor unit to improve the cooling effect.

[0061] Optionally, the plurality of water outlet channels 22 are evenly distributed in the second water storage tank 24 .

[0062] The water outlet channels 22 are evenly distributed, so that the spraying devices 3 are evenly distributed. When the spraying devices 3 spray the condensed water to the outdoor heat exchanger 11 , it is more even, and the cooling effect on the outdoor heat exchanger 11 is better.

[0063] Optionally, the outdoor unit further includes a water outlet switch and a controller. The water outlet switch is arranged at the connection between the water outlet channel 22 and the water storage chamber 21 to control the opening and closing of the water outlet channel 22; the controller is connected to the water outlet switch to control the opening and closing of the water outlet switch.

[0064] The water outlet switch can control the opening and closing of the water outlet channel 22, and the condensed water is stored in the water storage device 2. When the outdoor heat exchanger 11 needs to be cooled, the controller controls the water outlet switch to open, and the condensed water flows out from the water outlet channel 22. The spraying device 3 sprays the condensed water to the outdoor heat exchanger 11 to cool the outdoor heat exchanger 11. When the outdoor heat exchanger 11 does not need to be cooled or there is not too much condensed water stored in the water storage device 2, the controller controls the water outlet switch to close and waits for the water storage device 2 to store condensed water.

[0065] Optionally, the outdoor unit also includes a first water level sensor and a second water level sensor, the first water level sensor is arranged at the connection between the first water reservoir and the second water reservoir in the water storage chamber, and the second water level sensor is arranged at the highest position of the water storage chamber to detect the water level in the water storage device.

[0066] Combination Figure 7 As shown, a control method of an outdoor unit provided by an embodiment of the present disclosure is as follows:

[0067] S701, detecting whether the water level in the water storage device reaches the position of the first water level sensor;

[0068] S702, if it is detected that the water level has not reached the position of the first water level sensor, manually add water to the water storage device or wait for the water level in the water storage device to rise;

[0069] S703: If it is detected that the water level reaches the first water level sensor position, turn on the water outlet switch and spray the outdoor heat exchanger through the spraying device.

[0070] In the disclosed embodiment, by detecting whether the water level in the water storage device reaches the position of the first water level sensor, it is determined whether to turn on the water outlet switch and whether the spraying device sprays the outdoor heat exchanger. When the water level in the water storage device does not reach the first water level sensor, it means that there is no condensed water at the corresponding positions of some water outlet channels of the second water storage device. At this time, spraying cannot be performed directly to avoid uneven spraying. When the water level in the water storage device reaches the position of the first water level sensor, it means that there is condensed water stored at the corresponding positions of the water outlet channels of the second water storage device. At this time, the water outlet switch is turned on to spray the outdoor heat exchanger. Water is discharged from multiple water outlet channels at the same time, spraying is more uniform, and the cooling effect is better.

[0071] Combination Figure 8 As shown, another control method of an outdoor unit provided by an embodiment of the present disclosure is as follows:

[0072] S801, detecting whether the water level in the water storage device reaches the position of the first water level sensor;

[0073] S802, if it is detected that the water level has not reached the position of the first water level sensor, wait for the water level in the water storage device to rise;

[0074] S803, if it is detected that the water level reaches the first water level sensor position, detect the outdoor temperature;

[0075] S804, if the outdoor temperature is greater than 35°C, turn on the water outlet switch to spray the outdoor heat exchanger through the spraying device;

[0076] S805, if the outdoor temperature is less than 35°C, detecting whether the water level in the water storage device reaches the position of the second water level sensor;

[0077] S806, if the water level in the water storage device does not reach the position of the second water level sensor, turn off the water outlet switch and do not spray;

[0078] S807, if the water level in the water storage device reaches the position of the second water level sensor, turn on the water outlet switch, and spray the outdoor heat exchanger through the spraying device until the water level is lower than the first water storage device and stop spraying.

[0079] In the disclosed embodiment, first, whether the water level reaches the first water level sensor position is used as a judgment standard. If it meets the criteria, condensed water is stored in the corresponding positions of the water outlet channel. Then, the outdoor temperature is used as a judgment standard. If the temperature is greater than 35°C, the corresponding outdoor unit temperature is relatively high and urgently needs to be cooled. At this time, the water outlet switch is turned on to spray condensed water on the outdoor unit; if the temperature is less than 35°C, the outdoor unit does not urgently need to be cooled, then whether the water level reaches the second water level sensor position is used as a judgment standard. If it has reached, the condensed water in the water storage device is urgently consumed to prevent the condensed water from overflowing from the top opening. The water outlet switch can be turned on to spray the outdoor heat exchanger through the spraying device until the water level is lower than the first water storage device and the spraying is stopped; if the water level does not reach the second water level sensor position, the water in the water storage device is not urgently consumed, and the outdoor unit is not urgently cooled, then the water outlet switch can be kept closed and spraying is temporarily stopped.

[0080] An embodiment of the present disclosure provides an air conditioner, characterized by comprising an outdoor unit as described in any one of the above embodiments.

[0081] The air conditioner provided in the embodiment of the second aspect of the present application includes the outdoor unit described in any one of the embodiments of the first aspect, and thus has all the beneficial effects of the outdoor unit described in any one of the embodiments of the first aspect, which will not be repeated here.

[0082] Optionally, the air conditioner also includes an indoor unit and a water outlet pipe, the indoor unit is provided with a condensate outlet; the water outlet pipe, the water storage device is provided with a condensate inlet, the water outlet pipe is arranged between the condensate outlet and the condensate inlet, the height of the condensate outlet is higher than the height of the condensate inlet, so as to guide the condensate into the water storage device.

[0083] The water vapor in the indoor air generates condensed water through the evaporator of the indoor unit, enters the water outlet pipe through the condensed water outlet, and enters the water storage device 2 through the condensed water inlet. The height of the condensed water outlet is higher than the height of the condensed water inlet 25, so that after the condensed water is generated, it can enter the water storage device 2 through the water outlet pipe under the action of gravity. The condensed water inlet 25 is arranged in the first water storage tank. The condensed water flows from the first water storage tank 23 into the second water storage tank 24, and then is sprayed to the outdoor heat exchanger 11 by the spraying device 3 of the water outlet channel 22, so as to cool the outdoor heat exchanger 11 and improve the heat exchange efficiency of the outdoor unit.
