Description

Freezing cold-stored wind channel of electronic air door is prevented to side by side combination refrigerator

Technical Field

The utility model relates to the technical field of refrigeration components of refrigerators, in particular to a refrigerating air duct for preventing an electric air door of a side-by-side combination refrigerator from being frozen.

Background

At present, when an air door in the existing side-by-side combination refrigerator on the market is opened, an air supply passage is smooth, the air door cannot be frozen, when the air door is closed, cold air is blown to the air door and is blocked, and the temperature near the air door can be reduced to be below-15 ℃. On the other side of the air door, hot air in the refrigerating chamber flows back into the refrigerating air duct from the air outlet of the refrigerating chamber under the action of the natural convection buoyancy lift force, and is cooled and frosted when contacting with the air door. When the frosting is serious to a certain degree, the opening and closing action of the air door is blocked, and the air door cannot control the refrigerating temperature, so that the refrigerating is not carried out or the refrigerating is carried out till below zero.

The existing design solution: in order to prevent the freezing fault of the air door, the existing design is that an electric heating wire is generally arranged around the air door switch, and the air door switch is generally in a long-time working state in order to prevent the freezing of the air door switch. The power of the heating wire is generally 1W, and the power consumption is increased.

Experiments prove that even if the 1W heating wire is used for uninterruptedly heating the air door, the freezing problem of the air door is still not solved fundamentally, and the problem of insufficient heating power of the heating wire still exists.
