Gas stove timing pulse controller and gas stove adopting pulse controller

Abstract

The invention relates to a gas stove timing pulse controller and a gas stove adopting the pulse controller. With an existing timed flameout gas stove, for realizing the timing function, hardware such as a mechanical timer or an electronic timing circuit, a timing button, and the like should be added, such that cost is increased. According to the invention, only software but not hardware is changed. With a software upgrading manner, a timed flameout related program is added to a single-chip microcomputer of an original common pulse controller, such that the common pulse controller is upgraded into a timing pulse controller. The timing pulse controller is used for directly replacing the common pulse controller on an original gas stove, such that a solenoid valve on the gas stove can be closed through an original solenoid valve driving circuit by the timing pulse controller when a preset time is reached, and the gas stove timed flameout protection function is realized. According to the invention, the timed flameout function is obtained on the basis that the hardware is not changed and cost is not added, such that the cost performance of the product is improved.

Description

technical field [0001] The invention relates to a pulse controller and a gas stove, in particular to a timing pulse controller with the function of timing flameout and a timing gas stove using the timing pulse controller. Background technique [0002] Ordinary gas stoves do not have a timer function. If you forget to turn off the fire, it is easy to burn food or cause accidents. Existing timing gas stoves can solve the problem of forgetting to turn off the fire, but these gas stoves must add hardware or change hardware to realize the timing function, which not only increases the cost, but also cannot use the conventional general parts of the gas stove, which hinders production. bring inconvenience. These timing gas stoves may increase mechanical timing switches, such as Chinese patent 201220517713 "gas stove with timing function"; or increase electronic timing switches, such as Chinese patent 201310165675 "A new electronic timer for gas stove switch and its timing flameout ...
