Airflow dehumidification module applied to refrigerating and freezing device and refrigerating and freezing device

Abstract

The invention relates to an airflow dehumidification module applied to a refrigerating and freezing device and the refrigerating and freezing device. The refrigerating and freezing device is providedwith a storage chamber; the airflow dehumidification module comprises an air inlet pipe section, a cold transfer dehumidification pipe section and an air outlet pipe section which are sequentially communicated with each other; the air inlet pipe section is communicated with the external environment; the air outlet pipe section is communicated with the storage chamber; a fin assembly used for condensing and dehumidifying the airflow flowing from the external environment to the storage chamber is arranged in the cold transfer dehumidification pipe section, so that the airflow flowing to the storage chamber is dry airflow with extremely low humidity, the amount of the frost in the storage chamber is reduced, and the usage experience of a user is improved; the fin assembly is arranged and is used for enabling the amount of the frost in all the areas to be uniformly distributed; the airflow dehumidification module further comprises a heating device; the heating device is at least arranged on the outer wall of at least part of a pipe body of the cold transfer dehumidification pipe section and is used for accelerating thawing of the frost generated by the fin assembly; the heat generatedby the heating device on the outer wall of the at least part of the pipe body is uniformly distributed; and the frost thawing uniformity of the fin assembly is improved.

Description

technical field [0001] The invention relates to refrigerating and freezing technology, in particular to an airflow dehumidification module used for a refrigerating and freezing device and the refrigerating and freezing device. Background technique [0002] Refrigeration and freezing devices, such as refrigerators, freezers and freezers, are common electrical equipment used to store various items that need to be refrigerated or frozen, and are widely used in households, supermarkets and other industries. After being used for a period of time, the refrigerator and freezer will form frost on its inner wall (especially the freezer, the amount of frost produced by it is more obvious). An important reason for frosting is that when the compressor is turned on and off, the pressure inside the refrigerating and freezing device changes, and the humid air from the external environment enters the inside of the refrigerating and freezing device through the door gap, and then the moisture...

Problems solved by technology

However, the problem with this method is that the desiccant in the ventilation pipe has a short service life and needs to be replaced regularly, which is difficult to operate and increases the user's use cost; in addition, the hot air is directly introduced into the refrigerating and freezing device, which increases the cost of refrigerating and freezing. device energy consumption
