Embodiment Construction

[0010] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] See Fig. 1, make a refrigerated box with the technical scheme of the present invention, casing 1 is cylinder type, has insulation cover 2 on it, casing 1 inside has insulation layer 5, also has a freezing layer 6 in insulation layer 5, freezing Layer 6 is filled with refrigerant, which is a mixture of ice and salt in a ratio of 3:1. The inside of the freezing layer 6 is a freezing chamber 7 . Freezing chamber 7 is a detachable aluminum metal box, and the gap formed between the outer wall of this metal box and the insulation layer 5 inwall after putting on casing 1 center is freezing layer 6 . There is an airtight ring 3 at the opening of the casing 1 on the top of the freezing layer 6, and the airtight ring 3 is close to ...

Abstract

The invention relates to an environmental protection energy-saving portable cooling chamber without using electricity, which comprises a chamber body 1, a heat preservation cover 2 and a heat preservation layer 5. The invention is characterized in that: the heat preservation layer 2 has a freezing layer 6 internally filled with refrigerant. The freezing layer 6 has a freezing room 7 internally, which has a sealing ring 3 at the opening of the chamber body 1 at upper section; the sealing ring 3 is tightly adhered to the freezing room 7 and the heat preservation layer 5 to seal the freezing layer 6. A lifting handle 4 is arranged on external wall at upper section of the chamber body 1, which is convenient for carry when going out. By applying normal ice and salt as the refrigerant without using electricity, the invention has low cost and is able to be recovered and reused without polluting any environment. The technology is realized by adopting common technology as adding refrigeration layer in the heat preservation box, the invention has quick refrigeration effect and is able to keep the low temperature environment for long time, which has the advantages of low producing cost, light and easy for promotion, thereby being a revolutionary product in refrigeration industry.

Description

technical field [0001] The invention belongs to the field of civil refrigeration, and in particular relates to an environmentally friendly and energy-saving portable freezer that does not use electricity. Background technique [0002] Nowadays, as the climate continues to warm, various refrigeration products are widely used. For example, refrigerators are commonly used refrigeration products. The use of refrigerants cannot reduce its volume and weight enough, that is, car refrigerators, which are also expensive to use and inconvenient to use, and only a few car owners use them. For many people who have long-term outdoor activities in hot weather, portable refrigeration products are very necessary, except that some special items (such as medicines) need to be stored in a low temperature environment), and it is also necessary to carry some cold drinks with them, but at present There is no suitable portable refrigeration product to meet the demand. Contents of the invention ...
