Air-cooled refrigerator and air duct cover plate and cabinet of air-cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator and an air duct cover plate and a cabinet of the air-cooled refrigerator. The air duct cover plate of the air-cooled refrigerator is provided with strip-type air supply outlets which are transversely arranged, and wind is obliquely upwardly sent out through the strip-type air supply outlets. The air duct cover plate is simple in structure and convenient to manufacture; the strip-type outlets are transversely arranged in the air duct cover plate, so that trends that the wind sent out descends vertically are alleviated, closed areas are avoided forming among the neighboring air supply outlets due to the fact that a plurality of air supply outlets are formed, airflow dead corners are avoided, and condensation and frost formation are prevented inside the air-cooled refrigerator.

Description

technical field [0001] The present invention relates to the field of household appliances, and more specifically, relates to an air duct cover plate of an air-cooled refrigerator, a box body including the air duct cover plate, and a refrigerator including the box body. Background technique [0002] During the use of air-cooled refrigerators, condensation and frost are prone to occur on the surface of the tank, especially at the top of the freezer close to the door, where frost is prone to occur. In severe cases, the frost layer grows to the surface of the food, causing food to freeze. Bad, the performance of the refrigerator made is poor. [0003] The existing air-cooled refrigerator has the following disadvantages: [0004] The setting of the air supply port on the air duct cover plate of the existing air-cooled refrigerator mainly considers the uniformity of the temperature inside the tank, and does not consider the influence of the setting of the air supply port on conde...

Problems solved by technology

[0004] The setting of the air supply port on the air duct cover plate of the existing air-cooled refrigerator mainly considers the uniformity of the temperature inside the tank, and does not consider the influence of the setting of the air supply port on condensation and frost. Therefore, although the test found that the temperature in the tank is uniform The performance meets the requirements, but condensation and frost still exist on the top of the tank and other places

[0005] figure 1 and figure 2 The direction of the air outlet 11' at the top of the air duct cover plate 1' is shown. It can be seen that due to the influence of gravity, the wind blown out of the air outlet 11' gradually inclines from the horizontal direction to the vertical direction (such as figure 2 As shown by the arrow in , which indicates the direction of the wind blown by the air outlet 11'), resulting in a dead air flow at the top of the tank near the door; in addition, the layout of the air outlet 11' is also unreasonable, as multiple vertical ellipses Shaped air supply port, the vertical elliptical air supply port 11' accelerates the downward trend of the air flow, and the air supply port is arranged in a plurality along the horizontal direction, and a closed area 12' is formed between adjacent air supply ports, resulting in The top of the tank (that is: close to the door body) has little airflow distribution at the position corresponding to the closed area 12', which further intensifies the formation of the airflow dead angle 13', and the airflow dead angle 13' is prone to condensation and frost Therefore, with the current air duct structure, condensation and frost generally appear at the dead angle 13' of the air flow
