Abstract

The invention discloses a control circuit and a stove. The control circuit comprises a thermocouple, a negative pressure generation module, an electromagnetic valve and a detection control module, wherein the thermocouple comprises a first pin; the negative pressure generation module is used for generating a negative pressure; the electromagnetic valve comprises a first coil and a second coil; oneend of the first coil is grounded, and the other end of the first coil is connected with a first pin of the thermocouple; one end of the second coil is grounded, and the other end of the second coilis connected with the negative pressure generation module; and the detection control module is connected with the first pin, the other end of the second coil and a positive-voltage power supply separately, and used for communicating the other end of the second coil with the positive-voltage power supply when a heating temperature of the thermocouple is not higher than a first temperature, and disconnecting the other end of the second coil from the positive-voltage power supply when the heating temperature of the thermocouple is higher than the first temperature. According to the control circuit and the stove, the safety of the stove is improved.

Description

technical field [0001] The present application relates to the field of cookers, in particular to control circuits and cookers. Background technique [0002] Gas stoves are commonly used by household kitchen users. The gas switch of the stove is usually a solenoid valve. After the solenoid valve is energized, it attracts the valve core to control the opening of the gas inlet valve. After the solenoid valve is powered off, it resets under the action of the spring force to close the inlet valve. . [0003] In the prior art, in order to enable the cooker to close the solenoid valve immediately after the flame is turned off, software is used to actively control the solenoid valve. When using the software control method, if the software fails, the circuit may fail, and the solenoid valve cannot be closed in time, causing danger. [0004] Therefore, improving the safety of kitchen ranges is a problem to be solved urgently in this field. Contents of the invention [0005] The pr...
