Electric heating device and electric furnace

Abstract

The electric heating device comprises a heating panel, a heating element, a heat insulation part, a fixing shell, a temperature measuring element and a socket. The heating element is arranged on the lower side of the heating panel and is provided with a power connection part; the heat insulation part is provided with a heat insulation cavity which is opened on the upper side and used for covering the heating element; the fixed shell is provided with a shell cavity which is provided with an opening in the upper side and used for containing the heat insulation component, and the upper end of the fixed shell is connected with the heating panel through a bonding material; the temperature-measuring element is mounted at the bottom of the heat-insulating part; the socket is fixedly connected to the side portion of the fixing shell and electrically connected with the power connection portion and the temperature measuring element through a power supply wire and a detection wire, the power supply wire is arranged in the power supply wire groove, the detection wire is arranged in the detection wire groove, and the interface end of the socket faces the side portion of the fixing shell. The socket is arranged on the fixing shell, an external circuit can be quickly connected with the socket of the electric heating device through the plug during assembly, the assembly mode is simple, quick and reliable in operation and good in interchangeability, modular packaging is achieved, and the integrity of a product is good.

Description

technical field [0001] The invention relates to the technical field of electric furnaces, in particular to an electric heating device and an electric furnace. Background technique [0002] Electric ceramic stoves currently on the market generally include a casing, a core and a panel. The core includes a heating plate and a base of the core. The panel is arranged on the upper side of the heating plate. When working, the heat generated by the heating element in the heating plate heats the panel, and the panel heats the placed items. Electric ceramic stoves have a wide range of uses, with functions such as boiling water, frying, grilling, hot pot, stir-frying, heating milk, soup, and slow stewing, and are favored by consumers. [0003] The traditional movement does not consider the combination of the heating plate and the panel, resulting in a complex structure of the movement and the casing. The casing needs to be equipped with a bottom plate that can open the casing cavity, ...

Problems solved by technology

[0005] The existing movement connection is generally to connect a section of power supply wire and detection wire with the power connection part of the heating element and the temperature measurement element respectively as a terminal. Clamped or welded together, and the wire needs to be connected to fix the movement, which is troublesome to assemble. The wire lengths of different specifications of the shell are different, resulting in the need to customize different terminals for different specifications of the shell, and the interchangeability is poor.
