Technical Field

The invention relates to the technical field of fresh-keeping cabinets, in particular to a fresh-keeping cabinet for improving indoor environment and food materials.

Background

In the prior art, food material fresh-keeping cabinet is usually installed with circulation fan and evaporimeter at the back of fresh-keeping room, realizes the performance of eating the material through the lowering temperature, and its actual behavior is as follows:

firstly, the cold air passing through the heat exchanger circulates in the fresh-keeping chamber by means of the circulating fan, and then is injected into the cold air circulating channel through the cold air inlet positioned in the fresh-keeping chamber.

Then, the cool air passing through the cool air circulation passage moves along the cool air circulation passage located at the rear of the fresh food compartment, and is circulated toward the evaporator through the cool air flow inlet.

In general, the fresh-keeping cabinet having the above structure and operation mode is further provided with a freshness retaining device at the rear of the upper side of the fresh-keeping compartment, so as to eliminate odor components in the fresh-keeping compartment or keep freshness of stored fresh-keeping food.
