Abstract

The invention provides a refrigerating and freezing device. The refrigerating and freezing device comprises a tank, a nitrogen-making device and a sealed housing, wherein a storage chamber for storing goods is defined in the tank; the nitrogen-making device is used for providing nitrogen for the storage chamber, and the nitrogen-making device is provided with a nitrogen-oxygen separating assembly for separating nitrogen from oxygen in air, and an air compressor for providing compressed air for the nitrogen-oxygen separating assembly; and the sealed housing defines a containing space, and the air compressor is arranged in the containing space of the sealed housing. Due to the fact that the air compressor is arranged in the sealed housing, noise generated during operation of the air compressor can be lowered, and user experience is improved.

Description

technical field [0001] The invention relates to refrigeration and freezing technology, in particular to a refrigeration and freezing device. Background technique [0002] People's daily life is inseparable from various foods such as vegetables, fruits, fish, etc. These foods are usually stored by refrigerating and freezing devices such as refrigerators and freezers. However, for leafy vegetables and melons and fruits, since they are picked, they begin to undergo post-ripening process, causing the skins of the melons, fruits and vegetables to appear wrinkled and blotched. Although the low temperature environment in the refrigerating and freezing device can slow down the ripening of fruits and vegetables to a certain extent, the oxygen in the refrigerating and freezing device will still accelerate the deterioration of the food, resulting in an unsatisfactory quality preservation effect of the food in the refrigerating and freezing device. Therefore, the food stored in the ref...
