The outdoor unit of the air conditioner provided by the embodiment of the present disclosure includes a casing 10 and a humidifying device 20, the humidifying device 20 is disposed on the casing 10, the humidifying device 20 includes a liquid inlet 201 and an exhaust pipe 21, the liquid inlet 201 is connected with a branch pipe of a drain pipe of the air conditioner, and the exhaust pipe 21 is disposed outside the casing 10. When the outdoor unit of the air conditioner is in the self-cleaning frosting process, the humidifying device 20 changes the water flowing out of the drain pipe into water vapor and discharges the water vapor from the exhaust pipe 21. Therefore, the humidity of the air at the position of the air conditioner outdoor unit is increased, the frosting thickness of the air conditioner outdoor unit can be increased in the frosting process of the air conditioner outdoor unit, the frost layer is unfrozen in the subsequent defrosting process, enough moisture is available for cleaning the air conditioner outdoor unit, more dust on the surface of the air conditioner outdoor unit can be washed away, the self-cleaning efficiency of the air conditioner outdoor unit is improved, and the problem that the air conditioner outdoor unit cannot obtain enough moisture from a dry environment in the self-cleaning process to influence the self-cleaning effect of the air conditioner outdoor unit is avoided. Meanwhile, in the frosting process of the air conditioner outdoor unit, sewage in the drain pipe of the air conditioner can be utilized, the utilization rate of the sewage in the drain pipe is improved while the air conditioner outdoor unit carries out self-cleaning, and energy is saved.

Air flows into the outdoor unit from the air inlet side 101 and flows out of the outdoor unit from the air outlet side 102, so that heat can be better dissipated from the outdoor unit.

Alternatively, the exhaust duct 21 of the humidifying device 20 is provided on the intake side 101 of the cabinet 10.

It can be understood that the outdoor unit of the air conditioner usually deposits more dust on the air inlet side 101, and the exhaust pipe 21 is disposed on the air inlet side 101, so that more water vapor can be discharged on the air inlet side 101 by using the humidifying device 20, thereby making the frost layer condensed on the air inlet side 101 thicker, which is beneficial to improving the cleaning strength of the air inlet side 101 of the casing 10.

Alternatively, the output humidity of the humidifying device 20 is controlled according to the humidity of the outdoor environment detected by the humidity sensor. Under the condition that the outdoor environment humidity detected by the humidity sensor is lower than a first preset value, the air conditioner controls the output humidity of the humidifying device 20 to be a first humidity; in the case where the outdoor ambient humidity detected by the humidity sensor is higher than the first preset value, the air conditioner controls the output humidity of the humidifying device 20 to be the second humidity, where the first humidity is higher than the second humidity.

It is understood that in the case where the humidity of the outdoor environment is small, the air conditioner controls the output humidity of the humidifying device 20 to be large, that is, the humidifying device 20 discharges more water vapor; in the case where the humidity of the outdoor environment is high, the air conditioner controls the output humidity of the humidifying device 20 to be low, that is, the humidifying device 20 discharges less water vapor. Therefore, the output humidity of the humidifying device 20 can be timely adjusted according to the humidity of the outdoor environment detected by the humidity sensor in real time, so that the frosting thickness of the air conditioner outdoor unit is intelligently adjusted, and the self-cleaning efficiency of the air conditioner outdoor unit is improved.

The bent section 214 is disposed outside the sidewall between the air inlet side 101 and the air outlet side 102 of the casing 10, and extends from the air inlet side 101 of the casing 10 to the air outlet side 102 of the casing 10. In addition, the lower side of the bending section 214 is also provided with the air injection holes 213, so that the water vapor can be condensed into frost on the side wall between the air inlet side 101 and the air outlet side 102, and the cleaning effect of the air conditioner outdoor unit can be improved.

Optionally, a filter screen is disposed at the liquid inlet 201 to filter the water flowing into the humidifying device 20.

It can be understood that the water discharged from the drain pipe of the air conditioner may contain more impurities, and in order to maintain the cleanliness of the interior of the humidifying device 20, a filter screen may be disposed at the liquid inlet 201, and the filter screen may filter out the impurities and stains in the water flowing out of the drain pipe, so as to prevent the impurities in the water from entering the humidifying device 20, thereby affecting the normal operation of the humidifying device 20 and improving the reliability of the humidifying device 20.

Optionally, the filter screen is detachably disposed on the liquid inlet 201. Thus, when the meshes of the filter screen are blocked, the air conditioner can remind the user to replace the filter screen, and the condition that the humidifying device 20 cannot operate due to the blockage of the filter screen is avoided.

Alternatively, a drain pipe of the air conditioner is detachably connected to the inlet 201.

If in a certain period of time, the drain pipe discharged water of air conditioner is dirty, when leading to the filter screen often to be blockked up, the user can be dismantled the drain pipe from inlet 201, normally discharges the sewage in the drain pipe.

When the water storage amount in the humidifying device 20 is lower than a preset value, the valve of the control branch pipe is kept in an open state, so that the water in the drain pipe flows into the humidifying device 20. When the water storage amount in the humidifying device 20 is higher than the preset value, the valve of the control branch pipe is kept in a closed state, so that the water in the drain pipe does not flow into the humidifying device 20 and is normally discharged.

Alternatively, the opening and closing of the valves of the manifold may be controlled by a magnetically actuated switch. The magnetic switch can detect the water storage amount in the humidifying device 20, and automatically controls the opening of the valve on the branch pipe when the water storage amount is lower than a preset value; and when the water storage amount is higher than a preset value, the magnetic switch automatically controls the valve on the branch pipe to be closed.

In the embodiment of the present disclosure, the structure of the humidifying device 20 may be various, the humidifying device 20 may convert water into water vapor, and the conversion principle may be heating or atomization.

Alternatively, the output humidity of the humidifying device 20 may be controlled by controlling the rotation speed of the fan 24 and the power of the heating duct 23.

When the output humidity of the humidifying device 20 is high, the air conditioner controls the rotation speed of the fan 24 to increase, and increases the power of the heating pipe 23, so that more water is vaporized into water vapor and discharged from the exhaust pipe 21, thereby increasing the thickness of frost formed by the outdoor unit of the air conditioner. When the output humidity of the humidifying device 20 is low, the air conditioner controls the rotation speed of the fan 24 to be reduced, and reduces the power of the heating pipe 23, so that a small amount of water is vaporized into water vapor and discharged from the exhaust pipe 21, and the excessive thickness of the frost layer on the outdoor unit of the air conditioner is avoided.
