no. 1 example

[0020] see Figure 1-Figure 3 , the inner tank heating structure of this electric kettle includes a pot cover 5 and a pot body 2. A heating plate assembly 3 is arranged on the pot body 2. The temperature control part is electrically connected, and the temperature control part is an electronic temperature controller. The kettle body 2 is provided with a detachable liner 4, which is made of ceramics. The liner 4 is hollow, forming a cavity for holding food. The liner 4 is inserted into the kettle body 2 , and the pot cover 5 is sealed and connected with the kettle body 2 or the liner 4 . The bottom of the pot cover 5 extends a fixed boss, which cooperates with the opening of the mouth of the kettle body 2 / liner 4 and is fixed, and the top of the pot cover 5 is provided with a handle hole.

[0021] A positioning groove 2.1 is extended from the spout of the pot body 2, and the opening of the inner tank 4 is provided with a curling matching the positioning concave platform, and ...

Abstract

The invention discloses an inner-tank heating structure of an electric kettle, which comprises a kettle lid and a kettle body, wherein the kettle body is provided with a heating plate assembly, a water solution is filled into the kettle body, and a detachable inner tank is arranged in the kettle body; the inner tank is in a hollow structure forming a cavity for accommodating the food, and the inner tank is nested or inserted in the kettle body; and a positioning groove is protruded from an opening of the kettle body, the opening of the inner tank is provided with a turned edge or a flanged edge matched with the positioning groove, and the inner tank is attached to the groove. The inner-tank heating structure disclosed by the invention has the advantages that through adding the detachable inner tank in the kettle body, the functions of carrying out heating, stewing, heat preservation and the like on the food in the inner tank can be realized through transmitting the heat of the water solution in the kettle body to the inner tank according to the heat conduction property of the inner tank; when the ceramic inner tank is not required to be used, the inner tank can directly be taken out from the kettle body, and then the kettle can realize the function of boiling water through the heating of the heating plate assembly, because the outer wall of the inner tank is surrounded by the water solution and the outer wall of the kettle body, the heat loss can be reduced, and the heat transfer efficiency can be improved; and the inner-tank heating structure disclosed by the invention is simple and reasonable, energy-saving, and environmental-friendly, and is convenient and quick in assembling.

Description

technical field [0001] The invention relates to an electric kettle, in particular to an inner tank heating structure of the electric kettle. Background technique [0002] At present, general electric kettles only have the function of heating and boiling water, which has a single function and cannot meet some daily needs of consumers. If consumers need to heat and stew some food, they must buy special tools to realize it. [0003] Chinese Patent Document No. CN 2381241Y disclosed an electric kettle with a thermostat on June 7, 2000, including a kettle body, a kettle lid, a handle and a heating vessel. The tank is set in the middle of the concave part, and a temperature controller is set in the center of the heating tank. An inner tank is set on the shoulder of the concave part of the pot body. A temperature control protection device is installed in the central hole of the inner tank, and its bottom surface is close to A thermostat, and several micro-through holes are opened...
