Liquid heating vessel, heating tool and method for processing liquid heating vessel

Abstract

The invention discloses a liquid heating vessel. The liquid heating vessel comprises a vessel body and a heating body, the vessel body is used for containing liquid to be heated, the vessel body is made of non-metallic insulating materials, and the heating body is pre-buried at the bottom or / and in the side wall of the vessel body. When working, the heat generated by the heating body is directly transmitted to the vessel body, and the vessel body transfers the heat to the liquid to be heated. The invention further discloses a heating tool and a method for processing the liquid heating vessel.The liquid heating vessel is high in heat efficiency, simple in structure and convenient for mass processing.

Description

technical field [0001] The invention relates to the field of electric heating, in particular to a liquid heating container, a heating appliance using the liquid heating container and a method for processing the liquid heating container. Background technique [0002] The liquid heating containers in the prior art generally include a bottomless glass container and a metal heating plate, wherein the bottomless glass container and the metal heating plate are sealed by a silicone ring, and the processing of this type of metal heating plate needs to go through aluminum casting, A series of processes such as stainless steel stamping, brazing, and grinding and polishing are complicated, and these processing procedures seriously pollute the environment. At the same time, the heating tube on the metal heating plate is formed of a tubular or strip-shaped heating tube, and its heating is extremely uneven, which not only reduces the utilization rate of thermal efficiency, leads to waste ...

Problems solved by technology

[0005] 1. When using this all-glass electric kettle, although the carbon fiber heating plate can be heated to a very high temperature, the carbon fiber heating plate radiates heat to the bottom of the all-glass kettle body in the form of radiation emission, and then passes through the all-glass kettle body. The bottom of the pot conducts heat conduction, and in the process of heat radiation to the bottom of the all-glass pot, most of the heat has been lost, and the efficiency of this radiation heat transfer is very low; so even if the carbon fiber heating plate can be heated to 800 ° C, but the actual Only 200°C when reaching the liquid to be heated;

[0006] 3. The heating element of this all-glass electric kettle is generally installed in a glass tube, and its processing and installation process is complicated, and the process of its installation with the kettle body is complicated, which is not convenient for mass production, and its production cost is high;

[0007] 4. When using the all-glass electric kettle of this Chinese invention patent, since the temperature at the carbon fiber heating plate is quite different from the water temperature in the kettle body, if the temperature at the heating plate is directly detected, the detection accuracy is not high, so it is generally Directly detect the water temperature, but when directly detecting the water temperature, the probe is not easy to install; in addition, when using this all-glass electric kettle, the leakage protection function cannot be realized, resulting in extremely incomplete protection, and normal production cannot be carried out

[0008] In addition, in the prior art, there have been electric kettles that directly print a heating film on the bottom of the glass pot, but the heating film in this electric kettle is easily oxidized, resulting in a greatly reduced service life of the heating container
