Abstract

The invention provides a universal-type electric cooker long-time delay power socket, which is characterized by comprising a 220V AC power supply, a long-time delay charging circuit, a monostable circuit, a level phase inversion circuit, an electric cooker power socket control circuit and a 12V half-wave rectification filtering voltage regulation power supply, wherein a time base circuit IC1 in the monostable circuit adopts a model of NE555. In view of defects existing in the universal-type electric cooker, a circuit design and a making technology for making the time delay to exceed 30 minutes by using the time base circuit are bottlenecks hard to break through; in order to effectively solve the technical problem of long time delay of the time base circuit, on the basis of the typical time base circuit time delay circuit, several common elements are only added to the time delay circuit, and thus, the requirement for making a long-time delay circuit is realized. The problems that the universal-type electric cooker can not be timed and energy is wasted by continuous heating after the universal-type electric cooker is energized are solved, and the purposes of safety use and saved power of the electric cooker are achieved.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and relates to a long-time-delay power socket for a popular electric rice cooker. Background technique [0002] The popular electric rice cooker (not the computer version) only has a set of mechanical thermostats, and when the temperature of the heating plate in the electric rice cooker reaches 103°C, the power supply can be cut off. The heating plate in the rice cooker must reach 103°C, which can only be achieved by cooking rice. Cooking porridge, boiling noodles, boiling water, stewing chicken soup, steaming steamed buns, etc. cannot reach such a high temperature. Then, after the popular electric rice cooker is powered on, as long as you do not turn off the power of the electric rice cooker, the electric rice cooker will always be in a state of continuous heating until the water in the electric rice cooker is boiled dry. If you forget to turn off the power of the rice cooker when yo...
