Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Fig. 1 is the flow chart according to the control method of the air-valve of gas range aperture of one embodiment of the invention.
As shown in figure 1, the control method of the air-valve of gas range aperture of the embodiment of the present invention, comprises the following steps：
S101, detect the concentration and CO of CO during gas-fired stove cooking2Concentration.
Specifically, CO sensors and CO can be passed through respectively2CO concentration and CO during sensor detection gas-fired stove cooking2
Concentration.
S102, according to CO concentration and CO2Concentration determine the present combustion state of gas-cooker.
In the ideal situation, when the air of gas-cooker and the ratio of combustion gas reach certain value, combustion gas can fully burn, combustion
The gas that can be burnt again without CO etc. in generated gas is burnt, therefore the fired state is referred to as completely burned state；Work as sky
During gas relative deficiency, combustion gas causes the gas that can be burnt again containing CO etc. in the gas of generation because can not fully burn,
Therefore the fired state is referred to as imperfect combustion state.And in real life, due to only containing partial oxidation and combustion gas in air
In containing the factor such as impurity, combustion gas is producing CO in burning2While, it typically can all produce a certain amount of CO.Therefore, exist
In one embodiment of the present of invention, fired state during caused CO excessive concentrations can be set as imperfect combustion state.
In addition, after the amount of air meets the condition of combustion gas completely burned, if continuing to increase the amount of air, or reduce
The amount of combustion gas, because air themperature is relatively low, excessive air can absorb heat caused by a part of fuel gas buring, therefore can drop
The thermal efficiency of low burn gas kitchen.It should be appreciated that when the amount of air is relatively large or the amount of combustion gas is relatively small, caused by burning
CO concentration is relatively low, and CO2Concentration it is higher.Therefore, in one embodiment of the invention, can be by CO concentration and CO2It is dense

Insufficient state.In one embodiment of the invention, the first predetermined threshold value and the second predetermined threshold value can be because of the specific compositions of combustion gas
Different and change, inconvenience herein is defined to specifically be worth.
S103, the throttle opening of gas-cooker is controlled according to the present combustion state of gas-cooker.
Specifically, if present combustion state is imperfect combustion state, throttle opening is tuned up, so as to increase air
Amount, make fuel gas buring more abundant；If present combustion state is combustion gas deficiency state, throttle opening is turned down, so as to subtract
The amount of small air, improve the thermal efficiency of gas-cooker.
In one embodiment of the invention, by sending prompt message to the mobile terminal of user user can be prompted to adjust
Greatly or turn the throttle opening down, thus it is convenient and intelligent, and user experience is high.
In addition, when the amount of air is relatively extremely low and the amount of combustion gas is relatively high, combustion gas can produce greatly because of imperfect combustion
The CO of amount, now can not only waste combustion gas, more seriously be possible to jeopardize the health even person peace of user
Entirely.Therefore, the control method of the air-valve of gas range aperture of the embodiment of the present invention, can also include the steps of：Detect CO concentration
Whether the 3rd predetermined threshold value is more than；If CO concentration is more than the 3rd predetermined threshold value, alarm is sent, and send to mobile terminal
Warning message.
In one embodiment of the invention, when CO concentration exceedes safety standard (for example, can be 0.05%), combustion gas
Stove can directly issue the user with alarm sound, and send warning message to mobile terminal, be arranged accordingly with prompting user to take
Apply, for example, tuning up throttle opening, windowing ventilation as early as possible, closing gas-cooker or leave the environment etc..
It should be noted that it can be carried out between gas-cooker and mobile terminal by modes such as bluetooth, infrared or wireless networks
Communication.For example, the APP (Application, application program) on gas-cooker control, gas-cooker can be installed in the terminal
Information can be sent to the APP by built-in communication module.
The control method of air-valve of gas range aperture according to embodiments of the present invention, according to during gas-fired stove cooking CO it is dense
Degree and CO2Concentration determine the present combustion state of gas-cooker, and according to the present combustion state of gas-cooker to gas-cooker
Throttle opening is controlled, and so as to the aperture for conveniently and accurately making the air door of gas-cooker keep appropriate, can either make combustion gas
Fully burning, and can enough ensure the thermal efficiency of gas-cooker, therefore can save combustion gas resource, reduce environmental pollution, while can also prevent
The potential safety hazard only brought by CO excessive concentrations.
To realize the control method of the air-valve of gas range aperture of above-described embodiment, the invention also provides a kind of gas-cooker wind
The control device of door aperture.
