It relates to a condensate drain pump for air conditioners.

In general, the pump that automatically drains the condensate generated during the heat exchange process in the air conditioner is divided into a centrifugal pump method and a plunger pump method (also called a piston pump) using a solenoid.

The pump of the prior art mainly used as a condensate drainage pump for air conditioner as a centrifugal pump type is Korean Patent No. 10-0877236 and Utility Model Registration No. 20-0266036, Utility Model Registration No. 20-0300509, Utility Model A drain pump such as Model Registration No. 20-0438589 is disclosed.

However, since the centrifugal pump type condensate drain pump has a limitation in reducing the size of the motor and the impeller, there is a problem that it is not easy to install in a small place because the size is relatively large. It is mainly used for installation around air conditioners.

Condensate drainage pump for air conditioner of the plunger pump method using a solenoid relatively smaller than the condensate drainage pump of the centrifugal pump method of the Republic of Korea Patent Publication No. 10-2003-0045825 and the Utility Model Registration No. 20 Drain pumps such as -0423377 are used, and these drain pumps are mainly used for small wall-mounted air conditioners.

However, the drainage pump of the prior art has a structural defect in which the waterproof structure is incomplete, so there is a risk of short phenomena, and there is a problem in safety as well as a separate pump body and a controller (circuit), which limits the size reduction. It is not easy to be installed inside the air conditioner or to be installed in a straight duct or ceiling because it has a jagged structure, and as a result, it is very cumbersome and inconvenient for the construction work for condensate drainage of wall-mounted air conditioners. In addition, problems such as long construction time has been caused.

In particular, since the wall-mounted air conditioner is installed on a wall that is visually prominent, there is always a problem that the drainage pump must be installed inconspicuously.

Nevertheless, in the conventional installation of the drain pump, it is installed in the state exposed to the lower side of the air conditioner or installed in an elbow type duct for pipe piping connecting the outdoor air to the left or right side of the air conditioner, or left in the state above the ceiling of the upper part of the air conditioner. A method of installation has been disclosed.

However, in the installation method, because it is installed in a visually prominent place, it is not only aesthetic problem, but also requires a custom elbow duct suitable for the type of drainage pump. In addition, since the installation space is also very narrow, there is a problem that the installation is difficult or difficult to follow, and due to the characteristics of the position of the upper ceiling caused inconveniences such as inconvenience.

Therefore, it prevents water or moisture from penetrating the inside of the pump, ensuring safety and installing it in a narrow space inside the air conditioner. It can be installed not only with a pipe pipe inside a conventional straight duct sold as a ready-made product, but also easily on the ceiling. There is a need for a condensate drain pump for air conditioning that can be fixed and installed.
