The drain pipe of the ceiling-mounted air conditioning indoor unit is often led out of the casing from the top wall of the casing so as to be connected with an external pipeline when the ceiling-mounted air conditioning indoor unit is installed.
However, the drain pipe led out from the top wall of the casing increases the height of the top-suction type air conditioning indoor unit, which increases the packaging volume of the top-suction type air conditioning indoor unit, is not favorable for miniaturization of the top-suction type air conditioning indoor unit, and is not favorable for packaging and transportation of the top-suction type air conditioning indoor unit.
Disclosure of Invention
One of the objectives of the present invention is to provide a top suction type air conditioning indoor unit which has a compact structure, is advantageous for miniaturization, and is convenient for transportation.
In order to achieve the purpose, the top suction type air conditioner indoor unit provided by the invention comprises a shell, a heat exchanger and a drainage assembly, wherein the heat exchanger is fixedly arranged in the shell, the drainage assembly comprises a water pan, a drainage pump and a drainage pipe, the water pan and the drainage pump are fixedly arranged in the shell, the water pan is positioned below the heat exchanger, a water inlet of the drainage pump extends into the water pan, the drainage pipe is communicated with a water outlet of the drainage pump, and the drainage pipe penetrates out of the shell from the top wall of the shell; the top wall of the shell is provided with a concave containing groove, and the drain pipe is contained in the containing groove.
Therefore, through the structural design of the opposite-top-suction type air conditioner indoor unit, on one hand, the drain pipe extends out of the top wall of the shell, so that the drain pipe can be more conveniently drained by a continuous connecting pipeline in the process of installing the opposite-top-suction type air conditioner indoor unit on the roof of a user, and the installation difficulty of the opposite-top-suction type air conditioner indoor unit is favorably reduced; on the other hand, due to the arrangement of the accommodating groove, the height size of the top-suction type air conditioner indoor unit cannot be increased due to the fact that the drain pipe extends out, the top-suction type air conditioner indoor unit is compact in structure, the top-suction type air conditioner indoor unit is miniaturized, and packaging and transportation of the top-suction type air conditioner indoor unit are facilitated; in addition, the top wall of the top-suction type air-conditioning indoor unit belongs to the installation wall, so that the drain pipe extends out of the top wall of the shell and the accommodating groove is formed in the top wall of the shell, the appearance of a user on the top-suction type air-conditioning indoor unit cannot be influenced, and the top-suction type air-conditioning indoor unit is simple in external structure.
