Embodiment 1

[0024] like figure 1 , 2 As shown, a vacuum electric heating container structure includes an inner tank 1, an outer tank 2 and a heating device 3, and the heating device 3 is arranged at the lower part of the inner tank 1, and is characterized in that: the inner tank 1 and the outer tank 2 are at the mouth of the tank A vacuum layer is formed between the inner tank 1 and the outer tank 2, the heating device 3 is disposed in the vacuum layer as a whole, and the outer tank 2 is provided with a first through hole 7 for the conductor or the power line or the signal line to pass through. The above-mentioned first through hole 7 is in sealing connection with the conductor or the power line or the signal line. The heating device 3 is disposed in the vacuum layer as a whole, which can generate higher heating efficiency and ensure a longer heat preservation time, satisfying the effect of rapid heating and long time heat preservation of the liquid.

Embodiment 2

[0030] like image 3 , 4 As shown, the heating device 3 is a heating pipe, and the heating pipe includes a metal pipe 31 and a wire fixing member 32 arranged at the end of the metal pipe 31. The lower part of the wire fixing member 32 is fixed with a conductor connected to the power line. Pass through the first through hole 7 on the outer bladder 2. The conductor is a cold needle 33, the metal tube 31 is an aluminum tube, and the wire fixing member 32 is a ceramic tube. The ceramic tube plays the role of insulation, and the metal tube plays the role of heating. The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be described here again.

Embodiment 3

[0032] like Figure 5 As shown, the lower part of the inner tank 1 is also provided with an anti-dry heating protection device 6, which is integrally arranged in the vacuum layer, and the anti-dry heating protection device 6 includes a metal sheet 63 arranged at the bottom of the inner tank 1 and the sensor 61 , the sensor 61 is also connected with a power line or a signal line, and the power line or signal line passes through the first through hole 7 . In this solution, there are 2 through holes, one of which is used for conductors to pass through, which is similar to Embodiment 1, and the other through hole is used for the power line or signal line of the anti-dry burning protection device 6 to pass through, and the through holes are all With insulator.

Abstract

The invention relates to the field of a liquid heating device, in particular to a vacuum electric heating container structure, which comprises an inner liner, an outer liner and a heating device, wherein the heating device is arranged at the lower part of the inner liner. The vacuum electric heating container structure is characterized in that the inner liner and the outer liner are connected at the liner opening parts in a sealed way, a vacuum layer is formed between the inner liner and the outer liner, the whole body of the heating device is arranged in the vacuum layer, the outer liner is provided with a first through hole allowing a conducting body or a power supply wire or a signal wire to pass, and the first through hole is connected with the conducting body or the power supply wire or the signal wire in a sealed way. The vacuum electric heating container structure has the advantages that the structure is simple, the heat insulation effect is good, the whole body of the heating device is arranged in the vacuum layer, higher heating efficiency can be realized, and the effect of fast heating liquid is met.

Description

technical field [0001] The invention relates to the field of liquid heating devices, in particular to a vacuum electric heating container structure. Background technique [0002] Liquid heating devices are widely accepted and used due to their many advantages such as fast heating, energy saving and environmental protection. The initial liquid heating device generally used plastic molding or stainless steel stamping to make the body of the pot, but it was found that the device made by this method had poor thermal insulation performance and strong heat dissipation, and the liquid would cool down quickly, and the user had to reheat it frequently , resulting in a waste of resources, while repeated heating is not conducive to health. [0003] In the technical solution published by the Chinese patent CN100441131C authorized and announced on December 10, 2008, the vacuum connection layer is arranged between the bottom of the inner tank and the bottom of the outer tank, the edge of...
