Technical Field

The utility model relates to a household electrical appliances technical field, concretely relates to refrigeration plant's wind channel board subassembly and have its refrigeration plant.

Background

This section provides background information related to the present disclosure only and is not necessarily prior art.

In the air duct structure of the existing air-cooled refrigerator, cold air is sent out from an air outlet, when a door is frequently opened and closed or excessive food with moisture is thrown in at one time in summer, excessive water vapor enters a refrigerator, condensation water is formed at the air outlet with the maximum cold and hot temperature difference and nearby structures, the excessive condensation water is converged into large water drops, and the temperature becomes low and ice is formed when the refrigerator is closed for further refrigeration.

The main icing areas within the refrigerator include: 1) at the air outlet of the air duct, condensation water is most easily generated due to the lowest temperature of the air outlet, large water drops formed by aggregation are not easily blown away by wind in time, and ice is easily generated when the refrigeration temperature is low; 2) in order to prevent the phenomenon that a refrigerator is failed in refrigeration due to the fact that food is accumulated at an air outlet and cold air cannot be blown out by a user, structures protruding for a certain height are often designed near the air outlet of the air duct cover plate and are usually stopping ribs of rib structures, the structures can prevent the food from blocking the air inlet, but water is accumulated on the upper portions of the ribs or attached condensed water cannot flow out due to tension on the edges of the ribs to form ice; 3) as shown in fig. 1, when the amount of condensed water is large, the condensed water flowing down along the surface of the air duct cover plate 11 'will be collected into a water flow in the descending process, the lower flow rate is faster, in order to ensure the overall appearance and volume of the air duct cover plate 11', the lower portion of the air duct cover plate 11 'is designed to be a grille position for directly guiding the water to the lower portion of the return air inlet, however, when the amount of condensed water is large or the condensed water is frozen into ice and melted during defrosting, the condensed water is often splashed or flows into the inner container 20' due to large flow rate and fast flow rate, a water area is formed at the bottom of the freezing chamber (many refrigerators often have certain grooves for storing water because the water cannot be removed), thereby forming a large area of ice cubes Q, and too much ice cubes both affect the normal use of users and easily breed bacteria.
