Drain pan and air conditioner indoor unit

Abstract

The invention provides a water collecting plate and an indoor unit of an air conditioner. The water collecting plate comprises air guide surfaces. The air guide surfaces are positioned on the sides of a bottom surface of the water collecting plate. The water collecting plate and the indoor unit have the advantages that the air utilization rate is increased, accordingly, the heat exchange efficiency of an evaporator is improved, and noise of a unit is reduced; a water pump compression structure used for installing a water pump is arranged on the bottom surface of the water collecting plate, so that the water pump can be selectively installed on the unit, and after-sales installation is facilitated; a drain outlet compression structure used for being connected with a drain pipe is arranged on the bottom surface of the water collecting plate, and the bottom of the drain outlet compression structure is positioned on the lower side of a main plane of the bottom surface of the water collecting plate, so that the water outlet height can be effectively reduced, and water is prevented from spilling due to excessive water height; a heat exchanger side board can be effectively supported by the bottom surface of the water collecting plate, the evaporator can be effectively fixed, the quality of a product is improved, the product is multifunctional, a heat exchanger can be effectively supported, and production and installation are facilitated.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a water receiving tray for receiving condensed water from a heat exchanger and an air-conditioning indoor unit. Background technique [0002] In the air conditioner, the refrigerant enters the heat exchanger (indoor unit) from the energy-saving device. After the refrigerant reaches the heat exchanger from the capillary tube, the space suddenly increases and the pressure decreases. The liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant. Thereby absorbing a large amount of heat, the heat exchanger will become cold, and the fan of the indoor unit blows the indoor air through the heat exchanger, so what the indoor unit blows out is cold wind; the water vapor in the air meets the cold heat exchange After the air conditioner, it will condense into water droplets and flow out along the water pipe, which is why the air conditioner will le...

AI Technical Summary

Problems solved by technology

With the development of air conditioners, various condensate devices connected to heat exchangers have appeared in the air conditioner industry, but their functions are limited to the condensed water connected to heat exchangers, and some of them have the function of supporting heat exchangers. Performance, low noise and other requirements

That is to say, the function of the water tray is single and cannot optimize the performance of the air conditioner.
