A double-layer electric heating container

Abstract

The invention discloses a double-layer electric heating container, which comprises a water storage container, an outer shell coating the water storage container, and an electric heating element arranged at the bottom of the water storage container, and is characterized in that: a gap is reserved between the outer shell and the side wall of the water storage container to form a cavity; and the side wall of the water storage container is at least partially exposed out of the outer shell. The double-layer electric heating container has the advantages that: 1, the side wall of the water storage container is at least partially exposed out of the outer shell, so a consumer can see a double-layer structure of the electric heating container at a glance and can intuitively distinguish different materials of the water storage container and the outer shell to avoid misunderstanding; 2, the gap is reserved between the outer shell and the side wall of the water storage container to form the cavity, and an indicator light or a decorative light can be arranged at any position of the cavity; and 3, the water storage container and the outer shell coating the water storage container form the double-layer structure to achieve the effects of insulating heat, preventing scald, saving energy and preserving heat.

Description

Technical field: [0001] The invention relates to a double-layer electric heating capacitor. Background technique: [0002] Existing electric heating containers, especially electric kettles, are usually made of single-layer stainless steel material or plastic material or transparent glass. During the heating process, the electric kettle will become very hot and easily burn the user; in addition, after the water is boiled, , because the electric kettle is made of a single-layer material, the heat in the kettle is easily transferred to the outside air, and the heat preservation effect is not ideal. If you need to drink hot water, you need to heat it repeatedly, which is not conducive to energy saving. [0003] In order to solve the above problems, an improved method is to directly wrap a layer of heat-insulating protective cover on the outer wall of the kettle on the basis of the existing electric kettle, but the heat-insulating protective cover is directly in contact with the ...

[0002] Existing electric heating containers, especially electric kettles, are usually made of single-layer stainless steel material or plastic material or transparent glass. During the heating process, the electric kettle will become very hot and easily burn the user; in addition, after the water is boiled, , because the electric kettle is made of a single-layer material, the heat in the kettle is easily transferred to the outside air, and the heat preservation effect is not ideal. If you need to drink hot water, you need to heat it repeatedly, which is not conducive to energy saving

[0003] In order to solve the above problems, an improved method is to directly wrap a layer of heat-insulating protective cover on the outer wall of the kettle on the basis of the existing electric kettle, but the heat-insulating protective cover is directly in contact with the outer wall of the kettle, and the heat insulation effect Still unsatisfactory; Another kind of improvement method is to set up a plastic layer outside the single-layer stainless steel liner of existing electric kettle

However, this electric kettle has the following disadvantages: 1. The plastic layer completely covers the stainless steel liner. From the appearance alone, it is easy for consumers to mistakenly think that the electric kettle is made of a single layer of plastic, which cannot be intuitively reflected. Its inner layer is stainless steel, and the outer layer is a double-layer structure of plastic layer; 2. The plastic layer and the inner tank are almost completely close to each other, and it is impossible to set indicator lights or decorative lights on the plastic layer; 3. The inner tank and the plastic layer A waterproof sealing ring must be added between them to prevent water from penetrating into the outer plastic layer and the inner tank during the pouring process and causing water leakage. The structure is complex.

4. The outer plastic layer completely covers the inner tank. During the heating process, water vapor easily enters between the inner tank and the outer plastic layer through the spout and condenses into small water droplets, and finally discharges from the bottom of the plastic layer, which has water leakage and safety.
