Abstract

The utility model discloses a hot and cold insulation lunchbox, which comprises a cover body and a barrel, wherein a handle is fixedly connected to the upper surface of the cover body; the barrel consists of an inner barrel and an outer barrel; an annular cavity is formed in a gap between the inner barrel and the outer barrel; an anti-skid layer is formed on the bottom surface of the barrel; the barrel is provided with a cross-shaped partition plate; the cross-shaped partition plate partitions the inner barrel and the annular cavity into four chambers respectively along the height direction of the cross-shaped partition plate; a heat insulation layer is formed in two chambers of the annular cavity; and a water filling hole is formed on the upper part of the other two chambers of the annular cavity. Compared with the conventional heat insulation lunchbox, the hot and cold insulation lunchbox has the advantages that the handle is fixedly connected to the upper surface of the cover body, so that a user can conveniently carry and put down the hot and cold insulation lunchbox; the heat insulation layer is formed in the two chambers of the annular cavity, so that hot dishes can be placed and are subjected to heat insulation; the water filling hole is formed on the upper part of the other two chambers of the annular cavity, so that ice water can be filled into the annular cavity through the water filling hole according to requirements, and good icing and fresh-keeping effects are achieved; and the cross-shaped partition plate partitions the inner barrel into the four chambers, so that different kinds of food can be simultaneously placed.

Description

A kind of cold-hot heat preservation lunch box

Technical field

The utility model relates to a kind of lunch box, relates in particular to a kind of cold-hot heat preservation lunch box.

Background technology

Preservation drum is helping people to take in food, keep the fresh aspect of food to play certain effect, but existing fresh keeping barrel structure is single, only have insulation or cold storage function, fresh-keeping effect is relatively poor, without handle, very inconvenient when handling, without antiskid function, slide easily at smooth earth, cause the deuce to pay to people.

Summary of the invention

For the problem that above-mentioned prior art exists, the purpose of this utility model just is to provide a kind of cold-hot heat preservation lunch box that has solved above problem.

To achieve these goals, the technical solution adopted in the utility model is: a kind of cold-hot heat preservation lunch box, comprise lid and staving, described lid upper surface captive joint one handle, described staving is comprised of inner barrel and outer barrel, described space between the inner barrel and outer barrel forms an annular chamber, the staving bottom surface is provided with a skid resistant course, staving is provided with the cross dividing plate, described cross dividing plate is separated into respectively four chambers along its short transverse with interior bucket and ring cavity, be provided with heat-insulation layer in the chamber of described two annular chambers, described in addition two annular cavity tops offer water injection hole.

As preferably, described four chamber size equate.

As preferably, described cross dividing plate adopts thermal insulating material to make.

Compared with prior art, the utility model has the advantage of: lid upper surface captive joint one handle, be convenient for people to handling, be provided with heat-insulation layer in the chamber of described two annular chambers, but the heat release dish also is incubated, described in addition two annular cavity tops offer water injection hole, can in annular chamber, inject frozen water by water injection hole with the need, has preferably iced preservation, interior bucket is divided into four chambers by the cross dividing plate, can place simultaneously different types of food, bring great convenience to people in use.
