Indoor unit drainage system and air conditioner

Abstract

The invention relates to the technical field of air conditioner drainage, in particular to an indoor unit drainage system and an air conditioner, the indoor unit drainage system comprises an indoor unit, and the indoor unit comprises a bottom shell which is provided with cross-flow fan blades and an evaporator; a lower water pan used for supporting the front end of the evaporator and an upper water pan used for supporting the rear end of the evaporator are arranged at the front end and the rear end of the bottom shell respectively, the lower water pan comprises a lower drainage channel arranged in the length direction of the indoor unit, and a left drainage port and a right drainage port which are communicated with the lower drainage channel are formed in the left side and the right side of the indoor unit respectively. The upper water pan comprises an upper drainage channel arranged in the length direction of the indoor unit, a left drainage channel and a right drainage channel are arranged on the left side and the right side of the bottom shell correspondingly, the left drainage channel communicates with the left end of the upper drainage channel and the left end of the lower drainage channel, and the right drainage channel communicates with the right end of the upper drainage channel and the right end of the lower drainage channel. The upper drainage channel is in an arch shape with a high middle and two low sides. According to the system, water leakage of the indoor unit can be avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioning drainage, in particular to an indoor unit drainage system and an air conditioner. Background technique [0002] The drainage method of the existing wall-mounted air-conditioning internal unit is basically unilateral drainage. Through the design of the drainage structure, all the condensed water generated by the air-conditioning internal unit is guided to a drain port and then discharged outdoors through the drain hose. This kind of drainage structure is relatively simple, and it can basically meet the drainage requirements when the installation environment such as homes is stable and the installation location is flat. However, the unilateral drainage structure has certain limitations in bumpy and unstable environments such as large trucks or ships. When large trucks are driving on uneven roads or the ground where they are parked is uneven and the drainage outlet is not at the lowest point...

AI Technical Summary

Problems solved by technology

However, the unilateral drainage structure has certain limitations in bumpy and unstable environments such as large trucks or ships. When large trucks are driving on uneven roads or the ground where they are parked is uneven and the drainage outlet is not at the lowest point, it is easy to have an internal engine. Condensed water cannot be discharged and drips indoors, which greatly affects the user experience

In particular, the installation position in the cockpit of large trucks is uneven, and it is difficult to find the best balance angle during installation, which further increases the hidden danger of condensation water flowing into the indoor unit.
