Description

Crisper box that can maintain low temperature

Technical field

The utility model relates to the technical field of fresh-keeping boxes capable of maintaining low temperature, in particular to the technical field of fresh-keeping boxes capable of maintaining low temperature.

Background technique

As we all know, proper refrigeration of things can extend the shelf life of food. When using the refrigerator, we often use crisper boxes to store food in categories, which facilitates the orderly arrangement of food and avoids the transfer of odors between foods. In life, in addition to using crisper boxes to store food in the refrigerator, we also use them to store daily food outdoors. For example, we use crisper boxes to bring some cooked food as work meals or to store some fruits. However, when storing daily food outdoors, The storage temperature of the crisper will be affected by the outdoor temperature. For example, if we use the crisper to bring meals when the temperature is high in summer, it is likely that at noon, affected by the high temperature, the cooked food in the crisper will go rancid, and some berries will be sealed in The inside of the fresh-keeping box is also easy to get stuffy. In the existing technology, although there are some temperature-controlled fresh-keeping boxes, such as the square food supplement box with a built-in thermal insulation fresh-keeping box disclosed in the application number 201920588211. The lower or upper part is loaded with an insulated food-grade liquid that can be filled with freezable food-grade liquid. The food-supplement box is placed in the refrigerator and the freezable food-grade liquid in the insulated food-grade liquid is frozen into a solid state. Time, the insulated fresh-keeping box can continue to refrigerate or keep food supplements warm. However, only using a trace amount of freezable food-grade liquid on the lid of the box will have too little refrigeration effect on things, and it is also uneven. It is difficult to refrigerate the food at the bottom of the box. effect.
