the heat on the heat conduction base can be quickly and timely transmitted to the heat conduction medium in the heat conduction medium accommodating cavity through the first heat conduction part, the heat conduction medium with higher temperature flows out of the heat conduction medium accommodating cavity and is transmitted into the heat release cavity through the heat conduction medium transmission channel, the heat of the heat conduction medium with higher temperature in the heat release cavity is transmitted to the food materials to be thawed placed in the soft thawing accommodating barrel through the second heat conduction part for soft thawing of the food materials to be thawed, and then the heat conduction medium with lower temperature flows back to the heat conduction medium accommodating cavity through the heat conduction medium backflow channel and absorbs the heat from the heat conduction base again, so that the effect of circular heat dissipation can be realized, and the heat on the upright post can be quickly and timely absorbed by the transition device and the recovery device, so as to ensure that the temperature on the upright post reaches a lower level for maintaining the normal working performance of the LED luminous body.

It needs to point out very much, the heat-conducting medium will heat on the stand and heat on the semiconductor refrigeration piece quilt the heat-conducting medium carries to when being waited to unfreeze edible material and absorbing, can heat the edible material of waiting to unfreeze more mildly, its temperature is more suitable, and heats gentler, can realize soft unfreeze effect, recovery unit is more energy-conserving, and heating operation is gentler, accords with the theory that environmental protection and energy saving were advocated in present society.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
