A steam boiler control circuit

Abstract

The embodiment of the invention provides a control circuit for a steam kettle. The control circuit is used for achieving the purposes that time needed from heating to generation of a large amount of steam is smaller than 30 seconds, the speed is increased by more than 20 times compared with the existing speed, the size and weight are reduced by 2 / 3, light weight and convenience are achieved, and the use effect of the steam kettle is greatly improved. According to the technical scheme of the control circuit for the steam kettle, an MCU is electrically connected with a high-temperature heating circuit, a heat preservation circuit, a water inflow control circuit, a water level probe and an NTC. When the water level probe detects that the water level does not reach the preset water level, the MCU controls the water inflow control circuit to enable 80 ml of water to enter the steam kettle per 20 seconds, when the MCU detects that the bottom of the steam kettle does not reach the temperature of 120+ / -2 DEG C through the first NTC, the high-temperature heating circuit and the heat preservation circuit are controlled to heat the steam kettle through two sets of heating pipes connected with the high-temperature heating circuit and the heat preservation circuit respectively till it is detected that through the first NTC that the bottom of the steam kettle reaches the temperature of 120+ / -2 DEG C, and the MCU controls the heat preservation circuit to conduct heat preservation operation through the heating pipes connected with the heat preservation circuit.

Description

technical field [0001] The invention relates to the technical field of cooking for generating steam, in particular to a steam cooker control circuit. Background technique [0002] A steam pot, as the name suggests, is a pot body used to produce steam. The steam produced by the steam boiler is a kind of heat energy with environmental protection and low cost, so it is widely used in daily life. [0003] At present, the usual structure of a steam pot is a pot body, a heating component and a steaming frame. Water is placed in the pot body, and the heating pipe heats the water to a boiling point to generate steam. The steam is used to cook the food placed on the steaming frame. [0004] The defective of prior art is, the steam cooker product on the market at present takes about 7-8 minutes from heating to producing steam in a large amount, and the speed of producing steam is relatively slow, affects use. Contents of the invention [0005] The embodiment of the present inventi...
