Air supply and refrigerating system of refrigerator and refrigerator

Abstract

The invention provides an air supply and refrigerating system of a refrigerator. The air supply and refrigerating system comprises a top liner plate, a rear liner plate, an evaporator and a fan. The evaporator is fixedly arranged on the top liner plate, a rear air duct is arranged on the rear liner plate, a water disposal pan is arranged on the lower portion of the evaporator, the two sides of the water disposal pan wrap the evaporator and are connected with the top liner plate, a fan support is arranged on the front side of the water disposal pan, the rear side of the water disposal pan is communicated with the rear air duct, the fan is arranged on the fan support, the water disposal pan and the fan support are mutually independent parts or are respectively provided with independent space, the water disposal pan and the fan support are in mutual lap joint, and the water disposal pan, the fan support and the rear air duct form a sealed ventilation duct. The invention further provides a refrigerator with the air supply and refrigerating system. Stable airflow can be collected in the ventilation duct in the air supply and refrigerating system, heat exchange efficiency is greatly improved, the water disposal pan and the fan support are provided with independent space, condensing water is isolated from an electrical part on the fan side, water and electricity are separated, potential safety hazards are avoided, and the air supply and refrigerating system is easy to install.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator air supply and refrigeration system and a refrigerator. Background technique [0002] Medicine cabinets used in medical equipment usually use freezers. At present, the air supply and refrigeration system in the freezer mainly includes fans, evaporators, and inner and outer double-layer covers (such as figure 1 and 2 As shown), the inner cover is equipped with a fan and acts as a water receiving box at the same time. The air supply and refrigeration system structure has the following disadvantages: [0003] 1) The inner space of the inner cover is large, and the air in the box sucked by the fan cannot completely pass through the evaporator, and most of the air flow passes through the side and bottom of the evaporator, which does not get effective cooling, and the air flow is unstable, resulting in reduced reaction force The working efficiency of...
