Problems solved by technology

[0002] In daily life, all kinds of refrigeration products are widely used. As a household refrigeration product, refrigerators are widely used due to their large capacity, good cooling effect, and long cooling time. However, refrigerators are cooled by compressors, and the compressors themselves occupy a large As a result, the volume of the refrigerator is generally relatively large, and its volume and weight cannot be reduced enough to carry it with you, and the power consumption is high.
At present, there are a small number of refrigerated boxes. This kind of refrigerated box is composed of a box body, an insulating layer, a freezing layer and an insulating cover. It is small in size and easy to carry. The need for long-term freezing

specific Embodiment 1

[0020] Specific embodiment 1, under the above conditions, the selected capsule rupture time is 1 minute, the mass is 5 grams, the capacity is 10 ml, the temperature in the freezing chamber is -10°C, and the freezing time is 200 minutes;

specific Embodiment 2

[0021] Specific embodiment 2 is different from specific embodiment 1 in that: under the above conditions, the selected capsule rupture time is 10 minutes, the quality is 3 grams, the capacity is 3 milliliters, the temperature in the freezer is -6 ° C, and the capsule is frozen. Time 160 minutes;

specific Embodiment 3

[0022] Specific embodiment 3 is different from specific embodiments 1 and 2 in that: under the above conditions, the selected capsule rupture time is 60 minutes, the quality is 1 gram, the capacity is 5 milliliters, and the temperature in the freezer is -1 ° C. , the freezing time is 120 minutes;

[0023] This refrigeration box has good refrigeration and heat preservation effects. When ice and salt are added to the freezing layer 4, the temperature in the freezing chamber 5 drops rapidly. Relevant to the mixing speed of salt, in order to avoid the operation of continuously adding salt, the present invention packs granular salt in capsule shells containing different qualities of sorbitol. There are 5 kinds of capsules, and the ratio of sorbitol in the capsule shell is 1 mg:5 mg : 10 mg: 30 mg: 60 mg, the capsule shell melts and breaks in water for 1 minute, 5 minutes, 10 minutes, 30 minutes and 60 minutes respectively, depending on the salt particles entering the ice salt mixtu...

Abstract

The invention discloses a portable freezing cabinet which comprises a cabinet body, a thermal insulating cover, a thermal insulating layer, a freezing layer and a freezing chamber, wherein the thermal insulating cover is covered on the cabinet body; the thermal insulating layer is arranged in the cabinet body, the freezing layer is arranged in the thermal insulating layer, and the freezing chamber is arranged in the freezing layer; the freezing layer is filled with a refrigerant; the freezing layer is a vacuum liner, and the refrigerant is prepared through mixing ices and granular salts packaged in capsules (the weight ratio of the ice to the granular salt is 6:1); and the capsule used in the invention refers to five types of capsules, the ratio of the sorbitol contents of the shells of the capsules is 1:5:10:30:60, and the times for melting and fracturing the shells of the capsules in water are respectively 1 minute, 5 minutes, 10 minutes, 30 minutes and 60 minutes. The portable freezing cabinet disclosed by the invention has the advantages that the capsules are mixed in ice cakes, and then the mixture is stirred evenly, therefore, the melting time of the refrigerant is prolonged, the portable freezing the freezing effect is rapid, a low temperature environment can be maintained for a long time, and the freezing time is extended.

Description

technical field [0001] The invention relates to the field of civil refrigeration, in particular to a portable freezer. Background technique [0002] In daily life, all kinds of refrigeration products are widely used. As a household refrigeration product, refrigerators are widely used due to their large capacity, good cooling effect, and long cooling time. However, refrigerators are cooled by compressors, and the compressors themselves occupy a large Due to the limited space, the volume of the refrigerator is generally relatively large, and the volume and weight cannot be reduced to a sufficient extent, and it cannot be carried around, and the power consumption is high. At present, there are a small number of refrigerated boxes. This kind of refrigerated box is composed of a box body, an insulating layer, a freezing layer and an insulating cover. It is small in size and easy to carry. The need for long-term freezing. Contents of the invention [0003] In order to solve th...
