Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Fig. 1 is the flow chart of the control method of air-valve of gas range aperture according to an 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, detects concentration and the CO of CO in gas-fired stove cooking process
2concentration.
Particularly, can respectively by CO sensor and CO
2sensor detects concentration and the CO of CO in gas-fired stove cooking process
2concentration.
S102, according to concentration and the CO of CO
2the present combustion state of concentration determination gas-cooker.
In the ideal situation, when the air of gas-cooker and the ratio of combustion gas reach certain value, combustion gas can Thorough combustion, containing the gas that CO etc. can burn again in the gas that generates of burning, therefore claims this fired state to be complete fired state; When air relative deficiency, combustion gas, because of cannot Thorough combustion and the causing gas that can again can burn containing CO etc. in the gas generated, therefore claims this fired state to be imperfect combustion state.And in real life, owing to only containing containing factors such as impurity in partial oxidation and combustion gas in air, combustion gas, when burning, is producing CO
2while, generally all can produce a certain amount of CO.Therefore, in one embodiment of the invention, fired state during produced CO excessive concentration can be set as imperfect combustion state.
In addition, after the amount of air meets the condition that combustion gas burns completely, if continue the amount increasing air, or reduce the amount of combustion gas, because air themperature is lower, excessive air can absorb the heat that a part of fuel gas buring produces, and therefore can reduce the thermal efficiency of gas-cooker.Should be appreciated that when the amount amount that is relatively large or combustion gas of air is relatively little, the concentration of the CO produced that burns is lower, and CO
2concentration higher.Therefore, in one embodiment of the invention, can by the concentration of CO and CO
2concentration proportion lower time fired state be defined as the not enough state of combustion gas.
Particularly, if the concentration of CO is greater than the first predetermined threshold value, then determine that present combustion state is imperfect combustion state; If the concentration of CO and CO
2concentration between ratio be less than the second predetermined threshold value, then determine that present combustion state is the not enough state of combustion gas.In one embodiment of the invention, the first predetermined threshold value and the second predetermined threshold value can change because of the difference of gas utensil Body components, are defined as concrete value in this inconvenience.
S103, the throttle opening of present combustion state to gas-cooker according to gas-cooker controls.
Particularly, if present combustion state is imperfect combustion state, then throttle opening is tuned up, thus increase the amount of air, make fuel gas buring more abundant; If present combustion state is combustion gas deficiency state, then throttle opening is turned down, thus reduce the amount of air, improve the thermal efficiency of gas-cooker.
In one embodiment of the invention, send information by the mobile terminal to user, prompting user tunes up or turns down described throttle opening, and therefore convenient and intelligent, user experience is high.
In addition, when the amount antipode of air is low and the amount of combustion gas is relatively high, combustion gas can produce a large amount of CO because of imperfect combustion, now not only can waste combustion gas, more seriously likely can jeopardize the healthy even personal safety of user.Therefore, the control method of the air-valve of gas range aperture of the embodiment of the present invention, also can comprise the following steps: whether the concentration detecting CO is greater than the 3rd predetermined threshold value; If the concentration of CO is greater than the 3rd predetermined threshold value, then send warning, and send warning message to mobile terminal.
In one embodiment of the invention, when the concentration of CO exceedes safety standard (such as, can be 0.05%) time, gas-cooker can send alarm sound directly to user, and send warning message to mobile terminal, to point out user to take appropriate measures, such as, tune up throttle opening as early as possible, ventilation of windowing, close gas-cooker or leave this environment etc.
It should be noted that, communicate by modes such as bluetooth, infrared or wireless networks between gas-cooker with mobile terminal.Such as, can install the APP (Application, application program) controlled about gas-cooker in the terminal, gas-cooker sends information by built-in communication module to this APP.
According to the control method of the air-valve of gas range aperture of the embodiment of the present invention, according to concentration and the CO of CO in gas-fired stove cooking process
2concentration determine the present combustion state of gas-cooker, and control according to the throttle opening of present combustion state to gas-cooker of gas-cooker, thus can facilitate and make the aperture that the air door of gas-cooker keeps suitable exactly, combustion gas Thorough combustion can either be made, the thermal efficiency of gas-cooker can be ensured again, therefore can save combustion gas resource, reduce environmental pollution, also can prevent the potential safety hazard brought because of CO excessive concentration simultaneously.
