Abstract

The gas stove safety detection includes detection at high temperature and inside flame, timing detection of cooking period with gas stove, LCD to display the user state, and safety measures including overheat shutting, overtime shutting and no-flame shutting of the gas source to prevent gas leakage. The present invention makes the user understands the use state of the gas stove and ensures the safety of using gas stove.

Description

Gas stove safety detecting method

Technical field

The present invention relates to a kind of gas stove safety detecting method, particularly a kind ofly guarantee user's safer detection method when using gas oven.

Background technology

At present relevant manufacturing industry is all mechanically controlled gas, additional function is less, and to overcome flame-out escape midway, there is no other safety device in addition, can not ensure user's safety, therefore, easily cause the user under other careless mistake, to cause danger, for example the user forgets closed gas or the situation of leaking gas easily in the process of boiling when using gas oven, so that causes the loss of Personal Risk and property.

Therefore, the inventor concentrates on studies and cooperates the utilization of scientific principle, has designed a kind ofly to have considered above-mentioned factor and guarantee user's safer detection method when using gas oven.

Summary of the invention

One of purpose of the present invention, be to provide a gas stove safety detecting method, it detects in high temperature and flame detect at the user, and the time of using gas oven to boil carried out timing, with liquid crystal current state is shown simultaneously, so that make the user be easy to understand the time and the state of present use.

Another object of the present invention, be to provide a kind of user of order in the gas oven operating process, clearly to understand present user mode, and be provided with high temperature closed gas, the boil preferential actuator function that prevents gas leakage of securities such as closed gas and flame-out closed gas for a long time midway, so can guarantee that the user is safer when use gas.

In order to further specify feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet accompanying drawing explanation only for reference is limited the present invention.

Description of drawings

Fig. 1 is a circuit structure diagram of the present invention;

Fig. 2 is the flow chart of control module of the present invention when carrying out.

The specific embodiment

Fig. 1 is a circuit structure diagram of the present invention, include thermocouple 1, control module 2, magnetic valve 3, temperature detector 4, firepower magnetic valve 5, LCD (LCD) 6, console switch 7, caution unit 8 and key groups 9, wherein thermocouple 1, temperature detector 4, console switch 7 and key groups 9 are connected with the input of control module 2 respectively, and the output of control module 2 is connected with magnetic valve 3, firepower magnetic valve 5, LCD 6 and caution unit 8 respectively.

Thermocouple 1 is one can become temperature transition the voltage assembly, and it utilizes the variation of heat electric power to survey the variation of oxygen concentration in the Gas cooker combustion air, and delivers to control module 2 opens solenoid valve 3, makes the gas circulation, catches fire with affirmation.

Temperature detector 4 carries out temperature for control module 2 and differentiates in order to detect pan temperature to boil water.

Firepower magnetic valve 5 is when temperature to boil water reaches 100 ℃ of balances, and controlled unit 2 drives, and transfers little fire dechlorination to control firepower magnetic valve 5.

LCD 6 is in order to showing present use gas oven state, as time, temperature and unusual etc.

Console switch 7 is to boil water for setting, time, temperature etc.

Caution unit 8 flashes or warns sound when Gas cooker in use has unusual condition.

Key groups 9 contains button 91 to boil water, timing button 92 and constant temperature button 93, operates for the user.

Control module 2 is the runnings by internal processes, according to button or on-off action, carries out corresponding function, and that boils securities such as closed gas and flame-out closed gas midway as the high temperature closed gas, for a long time prevents the gas leakage function.

Fig. 2 is the flow chart of control module of the present invention when carrying out, set the inner initial value of start in step 21 during beginning, read outside perceptual signal (containing information such as temperature perception or flame perceptual signal) in step 22, carry out switch in step 23 and detect, whether using to detect the user.

If do not using then power cut-off; Otherwise whether the button that reads on the LCD panel in step 24 is pressed, and is presented on the LCD in step 25, then carries out wrong detection in step 26, and then demonstration or send caution sound on LCD to differentiate whether wrong generation, is arranged unusually as user mode.

If, then power cut-off; Otherwise,, and make the gas circulation by this detecting of catching fire lasting opens solenoid valve of confirming to fight in step 27 detection of catching fire.

(or because of flame-out midway) then do not finish and powered-down and gas if catch fire; Otherwise, select timing, constant temperature, to boil water or time detecting function in step 28.

Detect if desire to carry out timing function, press regularly button, then skip to regularly subprogram, carry out correlation function in step 281, if have unusually, then flame-out closed gas is finished power cut-off etc. function, otherwise, carry out oily temperature function in step 29 and detect, whether differentiate high temperature above 272 ℃.

If, then power cut-off; Otherwise, be back to step 22.

As if desiring to carry out the constant temperature Function detection, press the constant temperature button, go to the constant temperature subprogram in step 282, carry out correlation function, if having unusually, then flame-out closed gas is finished etc. function, power cut-off, otherwise, whether used continuously 3 hours in step 284 differentiation.

If used 3 hours then power cut-off continuously; Otherwise, execution in step 29.

If desire to carry out Function detection to boil water, press button to boil water, go to subprogram to boil water in step 283, carry out correlation function, if having unusually, then flame-out closed gas is finished etc. function, power cut-off, otherwise, execution in step 284.

If desire to carry out time detecting, then when button all is not pressed, carry out 3 hours time detecting that boil in step 284.

So, can for the user when boiling, more gas utensil cooked food can be used easily, the security of gas needn't be worried to use.

The above, it only is a kind of best specific embodiment of the present invention, yet feature of the present invention is not limited thereto, any person skilled in the art scholar in the field of the invention, can think easily and variation or modify all can be encompassed in the following claim scope of the present invention.
