[0002] When the air conditioner is running for cooling in hot weather, the spraying method can usually be used to spray coolant onto the outdoor unit heat exchanger to achieve evaporative cooling.

[0003] The spray system usually includes a nozzle base and a nozzle arranged on the nozzle base. In the related art, the nozzle bracket is arranged on the outdoor unit, and the nozzle is fixedly connected to the nozzle bracket. However, when this method is used to solve the problem of spray liquid coverage, it is necessary to continuously adjust the position of the nozzle base in the vertical direction to adjust the spray range of the nozzle. The whole adjustment process is relatively complicated. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a spray device and an air conditioner for an outdoor unit, which are used to quickly adjust the spray angle of the nozzle to ensure that the spray liquid can completely cover the surface of the heat exchanger.

[0005] A first aspect of the present application provides a spray device for an outdoor unit of an air conditioner, wherein the outdoor unit is provided with a heat exchanger, and the spray device comprises: a bracket, which is fixedly connected to a side surface of the outdoor unit, and an angle is formed between the bracket and the side surface; an adapter, which is movably connected to the bracket and is suitable for reciprocating relative to the bracket; and a nozzle, which is provided on the adapter and is used to spray spray liquid onto the heat exchanger.

[0006] In the above implementation process, the spray device includes a bracket, an adapter and a nozzle. The bracket is arranged on a side wall surface of the outdoor unit, the side surface corresponds to a side surface position along the height direction of the heat exchanger, and there is an angle between the bracket and the side wall surface, so that when the nozzle is installed on the bracket, the spray liquid sprayed by the nozzle can be sprayed on the heat exchanger; the adapter is movably connected to the bracket and can reciprocate relative to the bracket, the nozzle is arranged on the adapter and is arranged toward the heat exchanger, when the adapter moves relative to the bracket, the distance between the nozzle and the heat exchanger and the spray angle can be adjusted, and then it can be ensured that after the nozzle is installed, the distance between the nozzle and the heat exchanger is adjusted according to the size of the heat exchanger, so as to ensure that the spray liquid sprayed by the nozzle can completely cover the surface of the heat exchanger, thereby improving the cooling effect on the heat exchanger.

[0007] In a possible implementation, the first end of the bracket is fixedly connected to the side surface, and the bracket extends obliquely from the first end to the second end of the bracket in a direction away from the outdoor unit.

[0008] In the above implementation process, one end of the bracket is fixed to the outdoor unit, and the bracket extends upward obliquely away from the outdoor unit from the first end to the second end. In this way, when the adapter and the nozzle move along the extension direction of the bracket, the spraying angle of the nozzle also changes accordingly, so that the position when spraying the heat exchanger can be adjusted.

[0009] In a possible implementation manner, the bracket is provided with a chute, the chute extends along the extension direction of the bracket, the adapter is provided with a connection hole, and a fastener passes through the connection hole and the chute and is adapted to fix the adapter to the bracket.

[0010] In the above implementation process, by providing a chute in the length direction of the bracket and providing a connection hole on the adapter that is adapted to the chute, when the adapter moves relative to the bracket to a preset position, bolts and other fasteners can pass through the connection hole and the chute respectively to fix the adapter to the bracket. The structure and principle are relatively simple and easy to implement.

[0011] In a possible implementation manner, along the extension direction of the chute, at least one side of the chute is provided with scale lines, and the scale lines are used to mark the moving distance of the adapter relative to the bracket.

[0012] In the above implementation process, by providing scale lines on at least one side of the chute along the extension direction of the chute, when the adapter moves relative to the bracket, the moving distance of the adapter can be determined according to the scale lines, and it is convenient for the installer to install the adapter to the position corresponding to the preset scale lines according to the size of the heat exchanger.

[0014] In the above implementation process, the number of the chutes is two, the two chutes are arranged at intervals and both extend along the length direction of the bracket. Correspondingly, the number of the connection holes is also two and corresponds to the two chutes, which helps to improve the reliability of fixing the adapter to the bracket by the fasteners.

[0015] In a possible implementation manner, the adapter is provided with a communication hole, one end of the communication hole is used to communicate with the water inlet pipe, and the other end is used to communicate with the nozzle.

[0016] In the above implementation process, the adapter has a communication hole inside. Water inlets and outlets are respectively formed at both ends of the communication hole. The water inlets and outlets are respectively communicated with the water inlet pipe and the nozzle, so as to enable water flow to sequentially pass through the water inlet pipe and the adapter and enter the nozzle, and further realize spraying on the heat exchanger.

[0017] In a possible implementation manner, the nozzle includes a fan-shaped nozzle, and the spraying direction of the nozzle is parallel to the extending direction of the bracket.

[0018] In the above implementation process, the spraying liquid ejected by the fan-shaped nozzle is fan-shaped, and the spraying direction of the fan-shaped nozzle is parallel to the extending direction of the bracket. The bracket is inclined relative to the side wall surface of the outdoor unit. In this way, a spraying angle is formed between the nozzle and the heat exchanger, so that when the adapter moves relative to the bracket, the spraying angle of the nozzle can be adjusted.

[0019] In a possible implementation manner, it further includes: a water inlet pipe, and the nozzle is communicated with the water inlet pipe through the adapter.

[0020] In the above implementation process, a control switch can be arranged on the water inlet pipe, and the control switch is used to control the on-off of the water flow in the water inlet pipe to control whether the nozzle sprays.

[0021] In a possible implementation manner, the water inlet pipe is provided with a control switch; the spraying device further includes: a controller, and the controller is electrically connected to the control switch and is used to control the opening or closing of the control switch.

[0022] In the above implementation process, a control switch is arranged on the water inlet pipe, and the spraying device further includes a controller electrically connected to the control switch. The controller can be used to control the opening or closing of the control switch, so as to effectively improve the automation level of the nozzle spraying.

[0023] In a possible implementation manner, it further includes: a control box, the control box is arranged on the outdoor unit, and the control switch and the controller are both arranged in the control box.

[0024] In the above implementation process, by arranging the controller and the control switch in the control box, the control box can play a role in protecting the controller and the control switch, and prevent the controller and the control switch from being damaged during transportation or use.

[0028] In the above implementation process, since the spraying width of the nozzles can be obtained according to the specification models of the nozzles, and the heat - exchanger specifications of different outdoor units are different. When the specification model of the heat exchanger is obtained, the width of the heat exchanger can be known. In this way, according to the spraying width of the nozzles and the width of the heat exchanger, the number of nozzles to be installed can be obtained.

[0029] In a possible implementation manner, denote the distance between two adjacent nozzles along the width direction of the heat exchanger as L2, and L2 and b satisfy: L2 ≤ b.

[0030] In the above implementation process, after obtaining the number of nozzles to be installed, according to the number of nozzles, the spraying width of the nozzles, and the width of the heat exchanger, the installation positions of the nozzles in the width direction of the heat exchanger can be obtained.

[0031] In a possible implementation manner, the distance L3 between the nozzle closest to the first side in the width direction of the heat exchanger and the first side in the width direction of the heat exchanger and b satisfy: L3 ≤ b / 2.

[0032] In the above implementation process, by setting the distance between the nozzle on one side in the width direction of the heat exchanger and the edge in the width direction of the heat exchanger to be no greater than 1 / 2 of the spraying width, in this way, the spraying area of the nozzles can be ensured to completely cover the width direction of the heat exchanger.

[0034] In the above implementation process, the relationship between the distance L3 between the bottom of the side surface of the outdoor unit for mounting the bracket and the first end of the bracket and the distance L4 between the spray orifice of the nozzle and the bracket satisfies: Thus, it can be ensured that the spray liquid of the nozzle can be sprayed onto the top of the heat exchanger, so that the spray liquid can flow from the top of the heat exchanger to the bottom, and the spray liquid evaporates on the surface of the heat exchanger to achieve the cooling of the heat exchanger.

[0035] In a possible implementation manner, denote the distance between the spray position of the spray liquid on the heat exchanger and the bracket as L5, the distance between the surface of the side of the heat exchanger facing the bracket and the side surface of the outdoor unit where the bracket is installed as L6, and the relationship among L5, L6, and L4 satisfies:

[0036] In the above implementation process, L6 is specifically the distance between the side surface of the outdoor unit where the bracket is installed and the side surface of the heat exchanger facing the nozzle.
