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

Abstract

The invention relates to an airflow dehumidification module for a refrigerating and freezing device and the refrigerating and freezing device. The refrigerating and freezing device has a storage compartment. The airflow dehumidification module includes an air intake pipe section, a cooling and dehumidification pipe section and an air outlet pipe section which are connected in sequence, the air inlet pipe section communicates with the external environment, and the air outlet pipe section communicates with the storage compartment. The cooling and dehumidification pipe section is equipped with a fin assembly for condensing and dehumidifying the airflow flowing from the external environment to the storage compartment, so that the airflow flowing to the storage compartment is a dry airflow with very low humidity, reducing the humidity in the storage compartment. The amount of frosting improves the user experience. The fin assembly is arranged such that the amount of frosting is evenly distributed across its various areas. The airflow dehumidification module also includes a heating device, the heating device is arranged at least on the outer wall of at least part of the pipe body of the cooling dehumidification pipe section, and is used to promote the melting of the frost generated by the fin assembly; and the heating device is installed on the outer wall of at least part of the pipe body The heat is evenly distributed, which improves the uniformity of defrosting of the fin assembly.

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...
