Wine cabinet or refrigerator with refrigerator door glass defrosting function

Abstract

The invention relates to a wine cabinet or refrigerator with the refrigerator door glass defrosting function. The wine cabinet or refrigerator comprises a box body with a front opening, a door body, a compressor cavity arranged at the rear part of the lower part of the box body, an air inlet cavity and an air outlet cavity which are arranged on one side of the front part, a compressor, a condenser and an axial flow fan. The door body comprises a door frame, a glass door plate arranged on the door frame and a door seal arranged on the rear portion of the door frame. An air inlet hole is formed in a front wall plate of the air inlet cavity. The condenser is arranged in the air outlet cavity, and the axial flow fan is arranged on the rear portion of the air outlet cavity. A hot air outlet connector is arranged at the front end of the air outlet cavity and penetrates through a front wall plate of the air outlet cavity to extend out. The door frame is provided with an air inlet and a flow guide channel, and hot air in the flow guide channel flows on the front surface of the glass door plate. In a door closing state, the hot air outlet connector communicates with the flow guide channel. In the door opening state, the hot air outlet connector is disconnected from the communicating pipeline of the flow guide channel. Heat energy released by the condenser in the air outlet cavity is guided into the door frame to defrost the front surface of the glass door plate, and no damageable part exists. The service life is long and the cost is low.

Description

technical field [0001] The invention relates to a compressor refrigeration type wine cabinet or refrigerator. Background technique [0002] At present, wine cabinets or refrigerators on the market generally use transparent glass doors in order to better display the wine or beverages inside. However, the glass door has two very obvious disadvantages: poor thermal insulation effect and increased energy consumption; the glass surface is prone to condensation, causing the condensation water to drip on the ground, damaging the wooden floor, and poor user experience. [0003] According to the query data, the thermal conductivity of the foam door of the freezer is about 0.5W / (㎡.K), the thermal conductivity of the single-layer glass of the freezer is about 6.4W / (㎡.K), and the thermal conductivity of the insulating glass of the freezer is about 2.5- 3.5W / (㎡.K), the thermal conductivity of the hollow LOW-E glass of the freezer is about 1.2-1.8W / (㎡.K). That is to say, the best hollow...

Problems solved by technology

However, the glass door has two very obvious disadvantages: poor thermal insulation effect and increased energy consumption; the glass surface is prone to condensation, causing condensation water to drip on the ground, damaging the wooden floor, and poor user experience

The disadvantage of this method is: the electric heating glass is expensive, and in order to make the glass conduct electricity, it is necessary to design auxiliary components such as high-power power supply, connecting lines, controllers or sensors, which further increases the cost

The addition of electric heating elements also leads to a great increase in the energy consumption of the refrigerator, which may not meet the energy consumption regulations of some countries or regions, resulting in restricted sales markets
