Multifunctional thermal container

Abstract

The invention relates to a multifunctional thermal container. The multifunctional thermal container comprises a container body and a cover body, wherein a horizontal division plate is formed in the container body and divides the container body into an upper cavity and a lower cavity, and a metal container and heating elements are arranged on the upper side of the horizontal division plate, namely the upper cavity; a thermoelectric cooler is arranged on the middle portion of the lower cavity, and the thermoelectric cooler contacts the bottom of the metal container. The multifunctional thermal container not only has functions of heating, heat preserving and stewing, but also has functions of refrigerating and freshness retaining, the heat preservation sealing effect is excellent, and compared with the prior art, great improvement is achieved. The speed of heating and refrigerating is fast, and the response is agile. The multifunctional thermal container is convenient to carry and can be applicable to households, vehicles and the like, long-distance intelligent control can be achieved, and the practicability of the thermal container is greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of heat preservation boxes, in particular to a multifunctional heat preservation box. Background technique: [0002] With the development of society and the improvement of people's living standards, people's preservation of food is also getting higher and higher. Containers such as heat preservation boxes and fresh-keeping boxes are generally used for food preservation. At present, most of the thermal insulation boxes on the market do not have the function of heating, let alone cooling, so the thermal insulation is mostly based on passive thermal insulation, and the thermal insulation performance depends entirely on the material and structural design of the thermal insulation box. Of course, there are also some heat preservation boxes / fresh boxes with heating or cooling on the market, but the heating temperature of the existing heat preservation boxes can only be between 50°C and 80°C, which is determined ...

AI Technical Summary

Problems solved by technology

Of course, there are also some heat preservation boxes / fresh boxes with heating or cooling on the market, but the heating temperature of the existing heat preservation boxes can only be between 50°C and 80°C, which is determined by the type of heating element and The material of the insulation box itself is determined, because the existing heating element is generally made of electric heating wire and other materials, and the shell of the insulation box itself is generally made of plastic material, which has limited high temperature resistance, so the heating temperature of the design heating element generally cannot exceed 80 °C , so this kind of heat preservation box can only reach a temperature of about 60°C when heating food, especially cooked food, and cannot achieve the heating effect of reaching 100°C after boiling.

In addition, there are also thermal insulation boxes that use semiconductor refrigeration sheets as heating and cooling elements, relying on the adjustment of the current direction of semiconductor refrigeration sheets to achieve heating or cooling. The disadvantages are that the heating temperature cannot be too high and the heating speed is also slow.

[0003] In addition, most of the existing thermal insulation boxes are structurally composed of an outer shell and an inner tank, and the middle is a vacuum or filled with insulation cotton. The heating or cooling elements are directly installed at the bottom and in contact with the inner tank. Taking into account the needs of assembly, most of them are made of inner tanks. Removable method, this type of structure has poor seal between the inner tank and the outer shell, and water droplets are easy to enter, which brings safety hazards to the electronic components at the bottom

Furthermore, the lid of the heat preservation box is generally only made of plastic material, which cannot withstand high temperatures. This is also a factor that restricts the heat preservation box from being heated to a high temperature, and it is prone to deformation during use, which affects the sealing effect of the heat preservation box.
