Refrigeration and freezing device

Abstract

The invention relates to a refrigeration and freezing device. The refrigeration and freezing device comprises a basic-layer module with a freezing storage unit and a refrigerating system. Storage space is defined in the freezing storage unit. The refrigerating system comprises an evaporator used for being subjected to heat exchange with airflow flowing through the evaporator so as to at least provide cooling airflow for the freezing storage unit. A common air supply connector and two common air return connectors are arranged at the top of the basic-layer module. A primary air supply air flue and two primary air return air flues are arranged in the basic-layer module. The primary air supply air flue communicates with the storage space on the upper portion of the freezing storage unit, and the top end and the bottom end of the primary air supply air flue are connected to the common air supply connector and an evaporator chamber where the evaporator is located correspondingly. The top ends of the two primary air return air flues are connected to the two common air return connectors correspondingly, and the bottom ends of the two primary air return air flues are directly or indirectlyconnected to the evaporator chamber. According to the refrigeration and freezing device, a user can conveniently attach one or more function modules of other types to the basic-layer module.

Description

technical field [0001] The invention relates to refrigeration and freezing technology, in particular to a refrigeration and freezing device. Background technique [0002] The diversified demand for refrigerator functions in the family is increasing day by day. For example, some families are used to storing different types of food separately. There are great differences in the eating habits of different regions and different families. Different consumer groups have different volumes for each box of the refrigerator. The requirements for refrigerators are different in different seasons and periods, and traditional refrigerators cannot meet these individual needs of users. In addition, during the development and design process of refrigerator manufacturers, if they need to develop a new refrigerator for the expansion of new volume refrigerators, they often need to open more new molds, such as blister and foam molds, which greatly increases the development time.

Problems solved by technology

[0002] The diversified demand for refrigerator functions in the family is increasing day by day. For example, some families are used to storing different types of food separately. There are large differences in eating habits in different regions and different families. Different consumer groups have different volumes for each box of the refrigerator. The requirements for refrigerators are different in different seasons and periods, and traditional refrigerators cannot meet these individual needs of users.

In addition, in the development and design process of refrigerator manufacturers, if they need to develop a new refrigerator for the expansion of new volume refrigerators, they often need to open more new molds, such as blister molds and foam molds, which greatly increases the development time. Fees and Cycles

[0003] Traditional refrigerators mainly composed of storage compartments such as refrigerators and freezers and refrigeration compartments are relatively simple in terms of volume, size and function, and cannot meet the diverse needs of users.

For this reason, a kind of modular combined refrigerator has appeared in some existing patent literatures, and this modular combined refrigerator has only realized the independence between the freezing module with refrigeration system and other each functional modules on the level of theory, but It cannot essentially meet the diverse needs of users for arbitrarily replacing functional modules and changing the installation sequence of functional modules
