Referring to Fig. 1 and Fig. 2, the temperature control main body 2 is by ripple sylphon 10, driver plate 11, microswitch 12, terminal plate
13, the compositions such as temperature bar 14 are adjusted.
Referring to Fig. 1-Figure 11, then this kind of method and this kind of cubical expansion formula gas cooker overtemperature automatic extinguishing protective device are made as follows
Explanation：(1) kitchen range producer sets safe temperature, user's normal use gas-cooker in production as needed before kitchen range manufacture
When tool, the compression spring 8 in temperature-sensing probe component 1 pushes thermometer bulb 4 to be close to the bottom of a pan, experiences cooking bottom temperature, and protective cover 5 plays isolation and makees
With, so that temperature sensing package 4 is not influenced by gas flame temperature, while cold wind by 5 bottom of protective cover ventilation hole 17 to temperature sensing package 4
Persistently cool down, achievees the purpose that normally to monitor kettle temperature.(2) when cooking bottom temperature is excessively high, the medium in temperature sensing package 4
(temperature sensing liquid or gas) expanded by heating is conducted to the ripple sylphon 10 in temperature control main body 2 by conducting capillary 3, pushes
Ripple sylphon 10 forms a section and moves, and displacement pushes microswitch 12 to act by driver plate 11, cuts off electric signal, closes combustion gas
Solenoid valve, cuts off combustion gas, and kitchen range auto extinguishing achievees the purpose that anti-dry.(3) after pot leaves kitchen range, temperature-sensing probe component
The temperature sensing package 4 that links together in 1, protective cover 5, movable conduit 6 can rise automatically under the action of compression spring 8, the fire of combustion gas at this time
Flame and 4 close contact of temperature sensing package, the radiation of short distance heat transfer or the ventilation hole 17 by 5 bottom of protective cover, gas flame is straight
(burning) temperature sensing package 4 is contacted, temperature sensing package 4 rapidly heats up, and gives temperature control main body 2 to signal immediately, automatically cuts off combustion after a certain period of time
Gas prevents the generation of accident and fire.When pot is placed on kitchen range, due to the gravity of pot, compression press spring 8, temperature sensing package 4 is protected
Automatic-descending, cold wind, to 4 rapid cooling of temperature sensing package, are felt by the ventilation hole 17 of 5 bottom of protective cover together for shield 5, movable conduit 6
4 temperature of thermometer bulb reduces, and to 12 reset signal of microswitch in temperature control main body 2, connects gas electromagnetic valve power supply, normal to kitchen range
For institute.It should also be noted that this body expansion type temperature controller compared with electronic temperature controller, has apparent advantage：It uses
Long lifespan, affected by environment small, stable temperature control etc..
