Description

Can prevent heat preservation lunch-box of cold and hot dish heat transfer

Technical Field

The utility model belongs to the technical field of lunch boxes, and particularly relates to a heat preservation lunch box capable of preventing cold and hot dishes from heat transfer.

Background

The conventional heat-preservation lunch box consists of a cover, an outer box, a heat-preservation liner and an inner box placed in the lunch box, wherein the inner box is used for containing various foods. When in use, a user directly opens the cover to take out the inner box. The heat-preserving lunch box can only preserve heat or cool food at the same time, and can not preserve heat of hot dishes and cold dishes (such as fruits, cold dishes and the like) separately. When the hot dish and the cold dish are placed in the same heat preservation lunch box, the cold dish can become hot due to the heat of the hot dish, the hot dish can become cool, and the taste of food is affected. The hot dishes and the cold dishes are respectively placed in different heat-preservation lunch boxes, so that inconvenience is brought to a carrier, and in addition, the heat-preservation lunch boxes are sealed to the whole body only by the cover, so that the heat-preservation lunch boxes are not strong in sealing performance. In cold winter, as the temperature difference between the inside and outside environments of the heat-preserving lunch box is large, heat in the heat-preserving box is easy to run off, so that hot dishes in the heat-preserving lunch box quickly cool and can be eaten after being reheated; the patent number is a heat preservation lunch box of "CN202122755161.X", and it includes the heat insulating board, the heat insulating board is equipped with the exhaust hole and can open or close the shutoff component of exhaust hole, the heat insulating board detachable fixes between two adjacent interior boxes or detachable fixes between the interior box of placing the box body inside top with the upper cover. When in use, the inner box filled with hot dishes is firstly placed in the heat preservation lunch box, then the heat insulation plate is installed, the inner box filled with cold dishes is placed above the heat insulation plate, and finally the upper cover is covered to seal the whole heat preservation lunch box. According to the scheme, the heat insulation plates are used for respectively and separately insulating hot dishes and cold dishes in the same heat insulation lunch box, so that heat transfer between the hot dishes and the cold dishes is blocked, and meanwhile, the flavors of the hot dishes and the cold dishes are kept. In addition, the arrangement of the heat insulation plate forms secondary sealing on the inner box filled with the hot dishes, so that the heat insulation efficiency is improved; however, during the use of the above technical scheme, the stored dishes are in a stacked and listed design, the stacked design is extremely easy to cause the temperature to spread up and down, and the heat is generally spread from bottom to top during the storage and carrying process, so that the heat of the hot dishes is extremely easy to heat the bottom of the inner box body for a long time, thereby influencing the heat of the cold dishes, and in the above technical scheme, the lunch box lacks the corresponding anti-collision and anti-falling capability, and the lunch box is extremely easy to fall from hands when being carried, thereby causing the lunch box to be damaged, and therefore, the improvement is needed.
