Detailed Description
For ease of understanding, the specific structure and operation of the present invention is further described herein with reference to FIGS. 1-4:
the concrete components of the invention include: power switch K0The system comprises a power module 50, an ignition and flameout protection module 60, a pot detection sensor 30, a normally open fire electromagnetic valve DCF1, a main fire electromagnetic valve DCF2 and a wind pressure switch KmAnd a blower 70, etc. When assembling, as shown in fig. 1, the wind pressure switch KmIs arranged at the air outlet of the blower 70 and is connected with the ignition and flameout protection module 60; the ignition and flameout protection module 60 is electrically connected to the ignition needle of the normally open flame igniter and the normally open flame solenoid valve DCF1 through the first control circuit b and the second control circuit c, respectively. In the embodiment of fig. 1, the pan detection sensor 30 and the power module 50 are connected via an intermediate relay KJ2Connecting, intermediate relay KJ2Re-controlled power-off delay relay KT3Interruption time-delay relay KT3And then controls the main fire solenoid valve DCF 2. The power module 50 is connected to the pot detection sensor 30, each solenoid valve, and each relay.
The specific work flow is as follows:
power switch K for stove0After turning on, the blower 70 is powered on and the ignition and misfire protection module 60 delays for a few seconds to achieve pre-purging of the furnace. During this period, if the wind pressure switch KmDetecting that the air pressure of the air outlet of the air blower 70 reaches a set value range, then the air pressure switch KmIn a closed state. In this case, when the delay is over, the IGNITION AND FIRE-OFF PROTECTION Module 60 initiates a high voltage ignition sequence, outputting a high voltage V as shown in FIG. 11At two rootAn electric arc is generated between the ignition needles and an excitation voltage V is output2And (3) feeding a normally open flame solenoid valve DCF1 to connect a normally open flame gas circuit to ignite the normally open flame.
② the ignition and flameout protection module 60 enters the 'working' state after detecting the normal combustion of the normally open fire by the flame detection sensor, and outputs the excitation voltage V as shown in figure 13To close the ignition and flameout protective relay KJ1(ii) a If the ignition and flameout protection module 60 detects that the combustion state of the normally open flame is abnormal through the flame detection sensor, the output voltage is low level, and the ignition and flameout protection relay KJ1When power is lost, the normally open contact K is enabled1And disconnecting and triggering the sound alarm circuit to give an alarm. The flame detection sensor is preferably a flame ion detection sensor.
③ when the pot is placed on the hearth, the diffuse reflection photoelectric sensor or the ultrasonic sensor, that is, the pot detecting sensor 30 outputs the high-level voltage V as shown in fig. 1 after detecting the sufficient quantity of light reflection signals4With normally open intermediate relay KJ2Normally open contact K for power supply2Closed and power-off time-delay relay KT3Normally open contact K for power supply3Closing, thereby energizing the main fire solenoid valve DCF 2. The power supply comes from the power module 50.
Fourthly, when the pan leaves the upper part of the hearth, the pan detecting sensor 30 outputs the voltage V because the pan detecting sensor cannot receive enough reflected light signals4Is at low level and has normally open contact K2Turn-off and power-off delay relay KT3The control coil power supply is cut off. Power-off delay relay KT3The delay threshold value is preset, and after the delay threshold value is reached, the power-off delay relay KT3Controlled normally open contact K3And is disconnected, power module 50 stops supplying power to the control coil of main fire solenoid valve DCF2, and main fire solenoid valve DCF2 closes. Aiming at the power-off time-delay relay KT3The time delay design, its benefit is avoided when the cook is cooking in the top pot, because the pan is in quick dynamic change state, probably not enough from the light signal intensity that the pan outside reflects back in a certain twinkling of an eye, leads to diffuse reflection photoelectric sensor or ultrasonic sensingOutput voltage V of the device4Low, resulting in the main fire being accidentally turned off; the design of this time delay can effectively play the effect of eliminating the interference of this accidental emergency, has strengthened the stability of preventing the idle running fever function.
And fifthly, repeating the third step and the fourth step when the pot is placed on the hearth again.
For the pan detection sensor 30, it is fixed at the fixing frame 10 on the stove rack, that is: the pot detection sensor 30 is arranged in the mounting box 20, and the purpose of controlling the irradiation of the pot is realized through the opening 21 on the slope surface 20 a. To ensure the real-time cleaning function of the sensing surface of the pan sensor, a cleaning medium is sprayed from the opening 21, and the cleaning medium flows down the flow guide plate shown in fig. 2 and finally flows out of the device through the flow guide hole 22.
The shape of the fixing frame 10 is shown in figure 1, when assembling, the fixing frame is hooked on a cooking range frame from bottom to top through a lower arc opening 12, and welding or thread fixed connection and the like can be adopted; the cornice 11 on the upper part of the fixing frame 10 naturally forms a waterproof structure similar to an eave, so that cleaning media which are naturally led out from the guide plate 31 and mixed with dirt cannot enter the fixing frame 10, and influence on internal sensing devices, corresponding signal lines and the like is avoided.
