Water pan assembly capable of avoiding freezing blockage, air conditioner and control method

Abstract

The invention provides a water pan assembly capable of avoiding freezing blockage, an air conditioner and a control method. The water pan assembly comprises a water pan body and a drain pan, wherein the drain pan is arranged on one side of the water pan body. According to the water pan assembly capable of avoiding the freezing blockage, the air conditioner and the control method, the drain pan isused for filtering condensate water, ice pieces and the like in the condensate water are left on the drain pan, the ice pieces are prevented from blocking drain holes, when the drain hole positions are frozen, a dredging structure is used for breaking and dredging frozen ice at the drain hole positions, then the effect of avoiding freezing and blocking is further improved, a water level detectionmechanism is used for detecting the water level inside the water pan body in real time, when the water level reaches a set value, whether the freezing problem exists in the water pan body or not is judged according to a corresponding control strategy to conduct corresponding icebreaking operation, and a risk that defrosting water overflows from the water pan body and flows to the ground of a refrigeration house to freeze the ground or pollute goods is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of drainage structures, in particular to a water receiving tray assembly, an air conditioner and a control method for avoiding freezing blockage. Background technique [0002] When the air cooler is working in the cold storage, it is easy to frost and freeze on the fins of the heat exchanger of the air cooler. If the frost and ice are thick, it will seriously affect the flow of air and reduce the heat exchange efficiency of the air cooler. At present, in order to solve the frosting problem of the heat exchange fins, the air cooler usually uses water defrosting or heating wire defrosting. However, during the defrosting process, large ice flakes will fall into the water receiving tray, and the ice flakes will often The drain pipe joint at the bottom is blocked, which prevents the defrosting water from flowing into the drain pipe smoothly, resulting in the following problems: 1. The defrosting water in the cold...
