Embodiment 1

[0035] combine Figure 1 to Figure 7 , a kind of ultra-low temperature storage refrigerator, comprising a main box body 1, a refrigerator main box door 11 is connected to the main box body 1, a freezing chamber 2 is arranged in the main box body 1, and a refrigeration room for freezing and cooling is arranged in the freezing chamber 2 Refrigeration components. At least one ultra-low temperature storage box 3 is arranged in the freezer compartment 2 .

[0036] The ultra-low temperature storage box 3 includes a low temperature box body 4, which is connected with a drawer assembly 5, and the low temperature box body 4 is connected with a cooling and heat dissipation mechanism 6, a temperature sensor 7 and a first low temperature control board 8, and the first low temperature control board 8 passes through the The first line 81 is connected to the main control board of the refrigerator in the main cabinet 1 .

[0037] The low-temperature box 4 includes a box seat 41 and a box co...

Embodiment 2

[0051] When the above-mentioned ultra-low temperature storage box is used, the ultra-low temperature storage box is installed in the freezing chamber of the refrigerator, and different numbers of ultra-low temperature storage boxes can be installed according to the size of the refrigerator. The refrigerator used in this embodiment is a larger double-door refrigerator, and multiple ultra-low temperature storage boxes can be placed in the freezing chamber of the refrigerator.

[0052] When assembling the above-mentioned ultra-low temperature storage box, the assembly process can firstly assemble the drawer assembly part separately, and then assemble the low temperature box body, and at the same time assemble the temperature sensor, refrigeration plate assembly, fan, main control board for the storage box and the electric control part After the wire harness and accessories are arranged and installed, the radiator plate assembly is assembled inside the box body. There are pipelines...

Embodiment 3

[0059] In the above-mentioned ultra-low temperature storage refrigerator, the ultra-low temperature freezing of items is realized, and the overall structure is simple. By setting an ultra-low temperature storage box with a novel structure, an independent low-temperature space storage at -60°C and below can be realized, and fresh-keeping and freezing high-end ingredients, etc. Special low temperature Items are required.

[0060] In the ultra-low temperature storage refrigerator, there is no traditional refrigeration method such as a compressor for refrigeration, the finished product is low, the production operation and maintenance are convenient, and it is easy to realize. The ultra-low temperature storage box can also be used alone. The low temperature box can be independently controlled and used as a refrigerator or freezer without the limitation of traditional refrigeration methods such as compressors. It can be used as a car refrigerator or in other harsh environments.

Abstract

The invention discloses an ultra-low temperature storage refrigerator, which comprises a main box body, a freezing chamber is arranged in the main box body, and at least one ultra-low temperature storage box is arranged in the freezing room. The ultra-low temperature storage box includes a low-temperature box body, which is connected with a drawer assembly. The low-temperature box body is connected with a cooling and heat dissipation mechanism, a temperature sensor and a first low-temperature control board. The first low-temperature control board communicates with the refrigerator in the main box through the first line. Main control board connection. The low-temperature box includes a box seat and a box cover. The box seat is provided with a first foam insulation layer, and the box cover is provided with a second foam insulation layer; the box cover is assembled to the box seat by buckles or screws. On the upper end, a first installation through hole is opened in the box cover, a fan is arranged in the first installation through hole, and an air inlet shell assembly is arranged above the fan. The freezer in the refrigerator is equipped with a new structure ultra-low temperature storage box, which realizes the storage function of ultra-low temperature ingredients in an independent space inside the refrigerator, and the cooling effect is good, and the overall adjustment is more stable.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an ultra-low temperature storage refrigerator. Background technique [0002] With the improvement of living standards and the advancement of science and technology, people put forward higher requirements for refrigeration products such as refrigerators. Different food materials have different storage temperatures, especially the storage temperature requirements for seafood and other treasures. Most refrigerators in the market can only Achieving storage at a temperature of minus 18°C ​​cannot meet the perfect storage needs of protein-rich fish. The storage temperature in the refrigerator has higher requirements. In order to ensure the storage time of ingredients and the freshness of preservation, ultra-low temperature storage has become the development of household refrigerators. Trend, lowering the temperature can greatly weaken the activity of the enzyme, reduce ...
