Accompanying drawing explanation
The accompanying drawing of the part constituting the present invention is used for providing a further understanding of the present invention, and the present invention's is schematic real
Execute example and illustrate for explaining the present invention, being not intended that inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is that the systemic-function of gas-cooker described in the embodiment of the present invention constitutes block diagram；
Fig. 2 is the gas leakage detection control flow with gas-cooker described in Fig. 1.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the present invention and the feature in embodiment can phases
Combination mutually.
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1 and Figure 2, present embodiment discloses a kind of gas-cooker with gas leakage alarm defencive function, including
The control device that is arranged in described gas-cooker, flameout protection electromagnetic valve, External leakage detection device, internal leakage detection device
And wireless module, this control device includes main control chip, the first comparison circuit, the second comparison circuit, D/A converting circuit, gas
Plant selection circuit, firing circuit, air valve control circuit and warning circuit.For Appropriate application gas-cooker inner space, this portion
Parallel circuit can be integrated in a master controller, the reserved interface carrying out communication with peripheral components on master controller.Foregoing circuit
In, this first comparison circuit, the second comparison circuit, firing circuit, air valve control circuit and warning circuit all with described master control
Chip signal connects.
Described flameout protection electromagnetic valve, External leakage detection device and internal leakage detection device all with described control device
Signal connects, and described External leakage detection device is arranged on the exterior line of described gas-cooker, described internal leakage detection dress
Install on the pipeline within described gas-cooker.Described internal leakage detection device, described D/A converting circuit, described first ratio
Relatively circuit is connected with described main control chip, described External leakage detection device, described gas kind selection circuit, described digital-to-analogue conversion electricity
Road, described second comparison circuit are connected with described main control chip.Described internal leakage detection device and the detection of described External leakage
Device all includes gas security and for controlling the drive circuit of described gas security, the combustion gas of External leakage detection device
Sensor at least includes two kinds, constitutes a gas concentration detection device.When gas security detects leakage concentration change
After, concentration physical signalling is converted into the D/A converting circuit that analog electrical signal is sent to control in device and carries out signal processing,
Judged by the first comparison circuit and the second comparison circuit again.
The working condition of internal leak detecting device and external leakage detection device can be judged, i.e. by main control chip
Main control chip is normally connected (online) with internal leakage detection device and external leakage detection device, and system is properly functioning；If
Automatically controlled interface does not connect internal leakage detection device and external leakage detection device (off-line), does not examines leakage situation
Survey, but gas-cooker can normally use；If main control chip and internal leakage detection device and external leakage detection device be connected but
Go wrong (online fault), then gas-cooker can make fault prompting, informs user.Wherein off-line state represents that gas-cooker does not has
The function of gas leakage detection, so facilitates the functionally gradient of manufacturer's flexible planning gas-cooker, i.e. in same system platform
Under, gas leakage detection warning function can be made a matingplan and apply on gas-cooker.
The detection gas kind of internal leakage detection device keeps consistent with gas-cooker gas kind, the detection of External leakage detection device
Gas kind can carry out artificial selection by gas kind selection circuit, and the device of External leakage detection simultaneously also can be answered as product independent accessory
With, add its suitability after gas kind selects function and also increase.Can be according to the leakage combustion gas class detected in main control chip program
Preset corresponding alarm limits the most respectively, or user arranges the alarm limits of different combustion gas voluntarily according to the recommendation of manufacturer.
When main control chip detects internal leakage concentration higher than presetting or after the alarm limits of oneself setting, can send a pass
The signal of gas check valve, air valve control circuit can control the air valve in gas-cooker and close.Now, gas-cooker can be from normal operating condition
Become blowout protection state, or be constantly in holding state and forbid carrying out the action of igniting start.
When leakage occurs in gas-cooker external pipe, and leakage concentration is when reaching alarm limits, on gas-cooker can be carried out equally
Control described in face, plays the purpose of protection.External leakage detection device and internal leakage detection device are a kind of " logics or "
Relation, as long as the problem more than alarm limits occurs in side's concentration, gas-cooker all can carry out protection act.Carry out at gas-cooker
While protection act, also can be reported to the police, including leading to by warning circuit or the Anneta module being connected with main control chip signal
Cross voice, display screen prompting user or by the way of remotely control (such as cell-phone customer terminal, note, wechat etc.) in the very first time
Inside inform the leakage accident that user's family occurs, including the place leaked or leakage concentration etc..
The gas-cooker with gas leakage alarm defencive function of the present invention, because being provided with internal leakage detection device
With External leakage detect device, therefore the gas leakage problem that gas-cooker inside and residing space thereof are occurred all can carry out early warning and
Protection, it is achieved comprehensive monitoring, effectively stops the security incident owing to gas leakage causes and occurs.
Embodiment of the present invention also includes a kind of leakage protecting method based on above-mentioned gas-cooker, described leak protection side
Method main thought is to be respectively provided with internal leakage detection device and external leakage in the internal duct and exterior line of gas-cooker
Detection device, when described internal leakage detection device or external leakage detection device detect that gas leakage concentration reaches default
During alarm limits, gas-cooker then starts report to the police and disconnect fuel gas pipeline.In order to adapt to different gas families, on gas-cooker also
The gas kind selection circuit being connected with described external leakage detection device is set.Other details of method described in the present embodiment,
Similar with the working method of the gas-cooker of previous embodiment, do not repeat them here.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
