Abstract

The utility model relates to the technical field of air conditioners, in particular to an air conditioning system and a drainage system thereof, and aims to solve the problem that water in a drainage pipe and a drainage pump flows back into an air conditioner after the existing air conditioning system is shut down or powered off, and water is easy to leak. For this purpose, the drainage system of the air conditioning system of the present utility model includes a drain pump connected to a drain port of the drain pump, a drain pipe provided on the drain port or the drain pipe, and a check valve allowing only water to flow from the drain pump to the drain pipe. When the water pump is shut down or powered off, the check valve plays a role in cutting off, so that the water in the drain pipe cannot flow back, and under the action of negative pressure, the water in the drain pump cannot flow back, so that the water is kept in the drain pump. Namely, under the action of the check valve, the water in the drain pipe and the drain pump can be guaranteed not to flow backwards, and the risk of leakage of the air conditioner is reduced.

Description

Air conditioning system and drainage system thereof Technical Field The utility model relates to the technical field of air conditioners, and particularly provides an air conditioning system and a drainage system thereof. Background With the development of science and technology and society, an air conditioning system has become an indispensable electrical device for home or office. The indoor unit generates condensed water in a refrigerating mode, and the generated condensed water is discharged outwards through the drainage pump and the drainage pipe. In the existing upper drainage air conditioning system, after shutdown or power failure, condensed water in a drain pipe and a drainage pump can flow back into the air conditioner under the action of gravity and is stored in the air conditioner, and the risk of water leakage exists. Therefore, there is a need for an air conditioning system and a drainage system thereof to solve the above problems Disclosure of utility model The utility model aims to solve the technical problems that water in a drain pipe and a drain pump flows back to the inside of an air conditioner after the shutdown or the power failure of the existing air conditioning system, and water is easy to leak. In a first aspect, the present utility model provides a drain system for an air conditioning system, the drain system comprising a drain pump, a drain pipe connected to a drain port of the drain pump, and a check valve provided on the drain port or the drain pipe, the check valve allowing water to flow only from the drain pump to the drain pipe. In a specific embodiment of the drainage system of an air conditioning system, the check valve includes a connecting pipe, a sealing ring and a check member, the sealing ring is embedded in the connecting pipe, the check member is disposed in the connecting pipe and is located above the sealing ring, and when the drainage pump is closed, the check member can abut against the sealing ring to seal the connecting pipe. In a specific embodiment of the drainage system of an air conditioning system, the check member is a spherical member.
