Cascaded heating system and function detection method of system

Abstract

The invention provides a cascaded heating system and a function detection method of the system. The system comprises a main heating unit and a plurality of auxiliary heating units which can be electrically spliced with the main heating unit and can be electrically spliced with one another. The main heating unit and the auxiliary heating units are respectively provided with a heating circuit and aplurality of connecting terminals which enable all the heating circuits to be electrically connected in parallel. The main heating unit is also provided with a control circuit, a main power control switch and a power acquisition circuit. The method comprises the following steps: a main power control switch is in a conducting state after the system is electrified; a power acquisition circuit is arranged on a trunk of the heating system to acquire real-time electric parameter values, and corresponding real-time power values are calculated according to the electric parameter values; the real-timepower value is compared with a preset upper limit power value; when the real-time power value is larger than the upper limit power value, the power supply of the whole heating system is cut off through the main power control switch.

Description

technical field [0001] The invention relates to a cooking utensil with electric heating function, in particular to a cascadable heating system and a function detection method of the system. Background technique [0002] At present, cooking appliances with heating functions, such as electric grills, electric heating plates, rice cookers, induction cookers, electric pressure cookers, electric ceramic stoves, electric kettles, etc., all operate independently, and few similar products consider cascading with each other. implementation plan. In some applications, it is necessary to realize a larger or more flexible combination of heating surfaces. Obviously, there is no corresponding solution in the prior art, and generally only a plurality of similar electrical appliances can be used at the same time, which undoubtedly increases the cost, and for It is also a headache to plug in the power cords of multiple electrical appliances in the occasion with limited electric sockets. In...
