Safe gas cooker

Abstract

The invention discloses a safe gas cooker. Two cooking range assemblies and two corresponding ignition switches are arranged on the front upper surface of a cooker body; gas pipelines are extended into the cooker body from the rear part of the cooker body, are divided into two paths and are connected with the corresponding cooking range assemblies through the two ignition switches respectively; the two gas pipelines are provided with an electromagnetic valve respectively; the electromagnetic valves are positioned under the ignition switches; the front lower sides of the ignition switches are fixedly connected with the upper ends of linkage rods; springs are sleeved on the linkage rods; the lower ends of the linkage rods are pressed against the upper ends of valve cores of the electromagnetic valves; and thermocouples are arranged close to the cooking range assemblies and are connected with electromagnetic valve coils through two guiding wires. The safe gas cooker has a flameout protection function; and when flames are quenched accidentally, a gas source can be turned off in time, so that the safe gas cooker has high safety.

Description

technical field [0001] The invention relates to the technical field of production of household gas cookers, in particular to a safe gas cooker capable of automatically cutting off the gas source. Background technique [0002] With the popularity of gas cookers, the safety protection of gas cookers has become increasingly prominent. At present, in addition to the common type, the gas stove structures sold on the market also have electronic type, computer-controlled type and automatic flame-out type. The gas stove gas valve automatic switch device composed of gears, gas stove gas valve, and flame regulating valve, when the cooker is separated from the gas stove, the flame is automatically extinguished by the micro switch pulse ignition automatic control circuit. The defects of this electronic gas stove are; The structure is complex, there are many parts, and the flame is automatically extinguished only when the cooker is separated from the gas stove. When the flame is extingu...

Problems solved by technology

At present, in addition to the common type, the gas stove structures sold on the market also have electronic type, computer-controlled type and automatic flame-out type. The gas stove gas valve automatic switch device composed of gears, gas stove gas valve, and flame regulating valve, when the cooker is separated from the gas stove, the flame is automatically extinguished by the micro switch pulse ignition automatic control circuit. The defects of this electronic gas stove are; The structure is complicated, there are many parts, and the flame is automatically extinguished only when the cooker is separated from the gas stove. When the flame is extinguished by the external wind, the gas source is still supplying gas, which brings safety problems

The computer-controlled gas stove is equipped with a computer control system, a temperature sensing head and an air leakage sensor, with a single-chip microcomputer as the core controller, which is connected with an external key disk circuit, a temperature measurement part, a gas leakage detection part, an infrared remote control receiving part, an output control part, Functional units such as the display part can realize various functions such as display, temperature control, detection, alarm, and remote control. When the user forgets that the gas stove is in use and is not at home when going out, the gas leakage cannot be eliminated in time

The automatic flameout type gas stove is equipped with a timing automatic flameout and normal gas supply valve combination device on the gas stove gas supply pipe, and is automatically turned off by a mechanical timing driver. It is controlled by the preset time. Once an abnormal situation occurs within the preset time, the gas source cannot be cut off in time.
