Description

Portable constant-temperature heat preservation device for stewing cups

Technical Field

The utility model relates to the technical field of heat preservation lunch boxes, in particular to a portable stewing pot constant temperature heat preservation device.

Background

The existing heat preservation bags on the market usually have no heating function, and the food must be reheated after heat is dissipated. Most of electronic lunch boxes are heating plates for stewing and heat preservation, and the mode needs to be matched with a temperature control device, so that the structure is complex and the cost is high. In addition, the electronic lunch box adopting the heating plate for heating is usually heated at the bottom of the container, and although the container can be subjected to overall heat transfer through water, the bottom of the container is in direct contact with the heating plate, so that the local heating efficiency of the bottom of the container is high, the inner box is heated unevenly, and food materials at the bottom of the inner box are easy to stick to the bottom.

Disclosure of Invention

An object of the utility model is to prior art current situation, provide a portable handleless cup constant temperature heat preservation device of stewing, it is simple and convenient to use, and the security performance is higher, and is favorable to reducing equipment cost, has good economic benefits.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a portable stewing cup constant-temperature heat preservation device mainly comprises a shell, a container and an inner box, wherein a heating module is arranged below the container, a heat conduction plate is attached to the bottom of the container, and the heat conduction plate is in contact with the heating module.

In the above scheme, the heating module is composed of a plurality of PTC heating modules or is a heating film.

Further, the heat-conducting plate extends to the container lateral wall by the container bottom, wraps up the latter half of container, effectively increases heat transfer area, and the heating is more even.

Preferably, the heat conducting plate is an aluminum plate.

Furthermore, the container is provided with an interlayer which can accommodate more than two inner boxes.

Furthermore, a sealing cover body is arranged above the shell.

Furthermore, the bottom of the inner box is provided with supporting legs, so that the heat transfer efficiency of the bottom of the inner box is prevented from being higher than that of other positions, and the inner box is basically subjected to heat transfer by water in the container.

Furthermore, an inner box cover is arranged above the inner box, so that the food smell of different inner boxes can be effectively prevented from being mixed.

The utility model has the advantages that:

1. the PTC heating module is beneficial to reducing energy consumption and equipment cost, and temperature limiting devices such as a temperature controller and a fuse are not needed, so that the PTC heating module is safe and reliable;

2. utilize aluminum plate to carry out half parcel formula heat transfer, make the container be heated evenly, the supporting legs design of box in combining makes interior box heat completely carries out the heat transfer through the water in the container, more accords with the even standard of being heated, makes the food after stewing delicious.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

please refer to fig. 1, which is a schematic structural view of a preferred embodiment of the present invention, the present invention is a portable stewing cup constant temperature keeping device, mainly comprising a casing 1, a container 2 and an inner box 3, wherein a sealing cover 11 is disposed above the casing 1. The heating module 4 is arranged below the container 2, the heating module 4 is composed of a plurality of PTC heating modules or is a heating film, the power of a single PTC heating module is within 10W, the power consumption is low, the heating temperature is lower than the melting point of PP plastic, and the selection range of inner box materials is favorably increased. Heat-conducting plate 21 has been attached to container 2 bottom, and heat-conducting plate 21 is preferably aluminum plate, and heat-conducting plate 21 contacts with heating module 4, and heating module 4 passes through heat-conducting plate 21 and transmits the temperature to container 2, and in order to make the heat transfer more even, heat-conducting plate 21 extends to container 2 lateral wall by container 2 bottom, wraps up the latter half of container 2, can be with the horizontal plane control of the liquid that holds in container 2 in heat-conducting plate 21's parcel scope, and the thermal efficiency is higher, and the heat transfer is more even.

The container 2 is provided with a separation layer 20 which can hold a plurality of inner boxes 3, thereby being convenient for stewing a plurality of dishes at one time.

Interior box 3 top is equipped with interior lid 32, and the smell of eating the material in box 3 mixes mutually in can effectively completely cutting off each, and interior box 3 bottom is equipped with supporting legs 31, and when interior box 3 was arranged in container 2, box 3 in the liquid in the container 2 can be wrapped up as far as, and 3 bottoms of box and the contact of container 2 bottom lead to local heat transfer efficiency to strengthen in avoiding, and box 3 is heated evenly in can further guaranteeing.

Of course, the above illustration is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so all equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
