Likewise, anti-dry speech prompting device also can externally send dry combustion method signal by WIFI reception devices, with transmission
To remote terminal, such as cell phone application.
6th, loss of ignition speech prompting device
For the loss of ignition speech prompting device of gas-cooker, including：
Detector for ignition, judges whether igniting starts in ignition process, and judges burner by temperature-sensitive thermocouple 301
300 whether firing up, judging igniting to start during 300 not firing up of burner, generating loss of ignition signal；
Speech prompting device 500, detector for ignition is electrically connected, loss of ignition is sent when receiving loss of ignition signal
Voice reminder.
Wherein, speech prompting device 500 includes speech chip 1 and loudspeaker 2, and speech chip 1 and loudspeaker 2 are arranged on envelope
Fill in housing 3, encapsulating housing 3 is independently installed in the housing 600 of gas-cooker.When receiving loss of ignition signal, voice core
Piece 1 drives loudspeaker 2 to send loss of ignition voice reminder.Loss of ignition detection means may also include ignition light, and igniting refers to
Show that lamp is opened when receiving loss of ignition signal and reveals waming color.Ignition light may also be configured in detector for ignition
Closed during failure.
Wherein, detector for ignition may include：
Battery current detection circuit, the current value at the both ends of battery 100 is detected in real time；
Temperature-sensitive thermocouple 301, sense the temperature of burner 300 and send electromotive force signal；And
Controller 201, is configured to：
The current value of detection is received, whether is fallen into setting initial firing current section and judged according to the current value of detection
Whether igniting starts；
Electromotive force signal is obtained in real time, and in electromotive force not from the low level shape less than lower predetermined threshold (such as 1mV)
When state rises to the high level state more than upper predetermined threshold (such as 2mV), the not firing up of burner 300 is judged；
The loss of ignition signal is generated when judging igniting startup and 300 not firing up of burner.
Referring to Fig. 7, loss of ignition speech prompting device is related to battery 100, temperature-sensitive thermocouple 301 and includes speech chip 1
Communication and data processing between the speech prompting device and controller 201 of loudspeaker 2.
Wherein, when pressing and twisting the preparation igniting of coal gas rotary valve 400, it need to judge whether igniting really starts.Referring to figure
8f, it is the initial firing current for gathering the both ends of battery 100 by the way of.During pulse firing, initial firing current is larger, usually 80mA
~120mA sections, therefore it is preferably 80mA~120mA to set initial firing current section.The initial firing current of collection falls into this section, then
It is considered as igniting to start.This judgement can be realized by independent comparators or the comparison circuit being integrated in controller etc., such as
The current value detected received is compared with the upper threshold value and lower threshold value in setting initial firing current section respectively, to judge to be
It is no to fall into the setting initial firing current section.The circuit structure and its logic element of this comparator or comparison circuit are ability
It is not described in detail herein known to field technique personnel.
Selectively, microswitch is touched when can also be pressed by coal gas rotary valve 400 to obtain trigger signal, decision-point
Fire starts, and now microswitch triggers igniting enabling signal when coal gas rotary valve 400 is pressed, i.e., by specific shown in Fig. 9 h
The jogging switches measurement circuit of example obtains signal H.Now controller 201 judges that igniting starts according to igniting enabling signal；
Temperature-sensitive thermocouple 301 includes being arranged on the thermocouple probe at burner 300 and is integrated in pulse igniter 200
Thermocouple detects circuit.Equally, obtain electromotive force signal in real time, i.e., by the specific thermocouple shown in Fig. 9 f detect circuit come
Sense the temperature of burner 300 and send electromotive force signal (voltage signal E corresponding to i.e.), and in electromotive force not from pre- less than lower
When determining the low level state of threshold value and rising to the high level state more than upper predetermined threshold, the not firing up of burner 300 is judged；
Loss of ignition signal is generated when judging igniting startup and 300 not firing up of burner.
Likewise, loss of ignition speech prompting device also can externally send loss of ignition signal by WIFI reception devices,
To be sent to remote terminal, such as cell phone application so that the user away from gas-cooker can also obtain the real-time monitoring letter to gas-cooker
Breath.Further, transmitting-receiving medium can be also used as by WIFI reception devices, pulse igniter is manipulated by remote terminal
200, and then remote control gas-cooker, especially carry out safety and close valve operation or send various alarm signals.
