Abstract
The utility model discloses a safe fire extinguishing protection device of a novel gas stove. The safe fire extinguishing protection device comprises a furnace end, a high-temperature sensor, a control circuit, an electromagnetic valve switch, a main gas path, an auxiliary gas path, a manual valve, an ignition switch and a manual ignition switch, wherein the auxiliary gas path is connected in parallel with the main gas path; the manual ignition switch is mounted on the auxiliary gas path; the ignition switch is connected with the control circuit; the manual valve is mounted in front of branches of the main gas path and the auxiliary gas path. Generally, the manual ignition switch is turned off, and the ignition switch is connected with the control circuit; if the furnace end is extinguished due to an abnormal reason, the high-temperature sensor detects extinguishing of flame and transmits a signal to the control circuit; the control circuit controls the electromagnetic valve switch to close the main gas path, so that external leakage of gas is avoided; when the electromagnetic valve switch is damaged, the ignition switch cannot be used for realizing ignition; at the moment, the manual valve is opened so as to turn on the manual ignition switch, and the auxiliary gas path is opened so as to realize ignition at the same time; therefore, the manual ignition switch can be used for realizing ignition under a condition that the electromagnetic valve switch is damaged.
Description
Technical field
The utility model relates to gas stove, relates in particular to a kind of gas stove safety shutdown protective device.
Background technology
In recent years, along with the universal use of gas appliance, its security performance is also paid close attention to by people day by day, the common eyes kitchen range of gas kitchen ranges multidigit of selling in the market, great majority do not have flame-out protection device function.And in routine use process due to wind, overflow meal or the suddenly provisional reason such as stop the supple of gas or steam, when burning and flame are extinguished, can within very short time, combustion gas continue to leak simultaneously, cause poisoning, meet the fiery accident such as fried and occur, create greater casualties and accident to user's lives and properties.
Summary of the invention
For above-mentioned deficiency, the utility model provides a kind of gas stove safety shutdown protective device.
The utility model is achieved through the following technical solutions: a kind of gas stove safety shutdown protective device, comprises burner, pyrostat, control circuit, electromagnetic valve switch, main gas circuit, secondary gas circuit, hand-operated valve, ignition switch, manual ignition switch; Pyrostat is arranged on burner and fires fiery position, pyrostat connects control circuit, control circuit connected electromagnetic valve switch, electromagnetic valve switch is arranged in main gas circuit, secondary gas circuit and main gas circuit are in parallel, manual ignition switch is arranged in secondary gas circuit, and ignition switch connects control circuit, and hand-operated valve is arranged on main gas circuit and secondary gas circuit and divides and support the front.
The usefulness of this utility model is: manual ignition switch is generally to cut out, and ignition switch connects control circuit; During use, open hand-operated valve, open ignition switch, control circuit is controlled electromagnetic valve switch and is opened, simultaneously igniting.When flame-out due to abnormal cause burner, pyrostat detects fray-out of flame, and signal is passed to control circuit, control circuit controls electromagnetic valve switch and cuts out main gas circuit, be unlikely to like this combustion gas is leaked, while causing light a fire next time, occur quick-fried pot, the phenomenon of lifting pot.When electromagnetic valve switch damages, can not light a fire by ignition switch; At this moment open hand-operated valve, open manual ignition switch, secondary gas circuit is opened, and igniting simultaneously so just can also be used manual ignition switch to light a fire when electromagnetic valve switch damages.
Accompanying drawing explanation
Fig. 1: the utility model principle schematic;
Fig. 2: the utility model overall schematic;
In figure: 1 burner, 2 pyrostats, 3 control circuits, 4 electromagnetic valve switch, 5 main gas circuits, 6 secondary gas circuits, 7 hand-operated valves, 8 ignition switches, 9 manual ignition switches.
The specific embodiment
A gas stove safety shutdown protective device, comprises burner 1, pyrostat 2, control circuit 3, electromagnetic valve switch 4, main gas circuit 5, secondary gas circuit 6, hand-operated valve 7, ignition switch 8, manual ignition switch 9; Pyrostat 2 is arranged on the burner 1 fiery position of combustion, pyrostat 2 connects control circuit 3, control circuit 3 connected electromagnetic valve switches 4, electromagnetic valve switch 4 is arranged in main gas circuit 5, secondary gas circuit 6 and 5 parallel connections of main gas circuit, manual ignition switch 9 is arranged in secondary gas circuit 6, and ignition switch 8 connects control circuit 3, and hand-operated valve 7 is arranged on main gas circuit 5 and secondary gas circuit is supported the front for 6 minutes.Manual ignition switch 9 generally cuts out, and ignition switch 8 connects control circuit 3; During use, open hand-operated valve 7, open ignition switch 8, control circuit control 3 is controlled electromagnetic valve switch 4 and is opened, simultaneously igniting.When because abnormal cause burner 1 is flame-out, pyrostat 2 detects fray-out of flame, and signal is passed to control circuit 3, control circuit 3 controls electromagnetic valve switch 4 and cuts out main gas circuit 5, be unlikely to like this combustion gas is leaked, while causing light a fire next time, occur quick-fried pot, the phenomenon of lifting pot.When electromagnetic valve switch 4 damages, can not light a fire by ignition switch 8; At this moment open hand-operated valve 7, open manual ignition switch 9, secondary gas circuit 6 is opened, and igniting simultaneously so just can also be used manual ignition switch 9 to light a fire when electromagnetic valve switch 4 damages.
