Abstract

The invention relates to a lower air duct plate used in an electric air door, which comprises a lower body, wherein a lower storage chamber is disposed on the upper end face of the lower body, and a lower air outlet is disposed in the side wall of the lower storage chamber; a drainage groove is disposed in the bottom face of the lower storage chamber, and a drainage through hole is also disposed in the bottom face of the lower storage chamber; and one end of the drainage groove is disposed near to the lower air outlet, and the other end of the drainage groove is connected to the drainage through hole. The invention also relates to an air duct assembly containing the lower air duct plate. The invention also relates to a refrigerator containing the air duct assembly. The lower air duct plate provided by the invention has the beneficial effect that the lower air duct plate has a simple structure and is processed conveniently, wherein the drainage groove can effectively discharge condensation dews in the lower storage chamber, and the technical problem that easy freezing of the air door and the assembly will make refrigeration of the whole refrigerator out of control is solved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a lower air duct plate, an air duct assembly and a refrigerator. Background technique [0002] In the air-cooled refrigerator, the electric damper is used to control the opening and closing of the air duct to adjust the temperature of each room of the refrigerator. The electric damper generally includes a base, a door frame, a door panel, an upper end cover and a lower end cover. However, there is a large temperature difference between the various rooms of the refrigerator, resulting in the formation of condensation water on the electric damper. When the temperature is lower than 0°C, the condensation water will freeze again. The icing phenomenon interferes with the normal operation of the electric damper: when it is opened, if the door panel of the electric damper is frozen, the electric damper will not be able to open; The room (refrigerated room, cold room) is too cold. ...
