The specific embodiment

Please with reference to shown in Figure 2, in present embodiment, a kind of refrigerator with regenerator; Comprise case shell 24, inner bag 21, between said inner bag 21 lateral walls and case shell 24, place evaporimeter 22 and regenerator 26 successively, said regenerator 26 has groove near the one side of inner bag 21 lateral walls; Pass in the groove of said evaporimeter 22 from the said regenerator 26; Said regenerator 26 is formed by plastics blow molding, and said evaporimeter 22 is a pipe-coil type evaporator, and said regenerator 26 is made up of regenerator box and 25 of cold-storage liquid being loaded in the regenerator box; Said regenerator box is a flattened rectangular shape structure; Said cold-storage liquid 25 is distilled water, and its complementary space between inner bag 21 and case shell 24 is foaming layer 23, is filled with foaming thermal-insulating in it.

During installation, directly regenerator 26 is attached on inner bag 21 lateral walls, does not change the product volume, and after the foaming thermal-insulating foaming, regenerator 26 just has been embedded between foaming thermal-insulating and the inner bag 21.

During work, refrigeration compressor starts, and is arranged at evaporimeter 22 absorption refrigerations of inner bag lateral wall; To regenerator 26 and the uniform released cold quantity in inner space, the cold-storage liquid 25 of dress absorbs cold in the regenerator box, and cold-storage liquid 25 temperature reduce; During normal the use, refrigeration system operation and when stopping, through the cold-storage of regenerator and between inside the chamber released cold quantity; Make that the temperature fluctuation range of inner space is littler than general refrigerator, temperature is more stable.Having a power failure or other accident when causing refrigeration compressor to quit work; Regenerator 26 is the chamber released cold quantity between product inside; The cold that the inner space absorbs regenerator 26 releases reaches the cold insulation effect; Make the internal temperature fluctuation ratio not littler in the temperature fluctuation of same time period, can avoid or reduce user's loss to a certain extent with the regenerator product.
