Description

Fully automatic safety gas cooker

                                                                                                       

The utility model relates to a gas cooker, in particular to a fully automatic controlled safe gas cooker.

                    II. Background technology

With the continuous improvement of living standards, natural gas and coal gas are rapidly popularized in households, and the safe use of gas has attracted the attention and attention of the general public and the government. However, gas poisoning and explosion accidents still occur, causing heavy losses to society and families. The main reason is that the most commonly used ordinary cooker has no safety protection function. When the fire is not lit, the fire is blown out by the wind, the water is full to extinguish the fire after the water is boiled, and the pipeline gas stops suddenly, etc., the gas leaks accidentally. Accidents will happen if you are negligent. Although gas cookers with safety devices are also produced now, their structure is generally only to install thermocouples or probes on the stove to realize accidental flameout and gas shutdown. Gas cookers with this structure have low control accuracy and poor safety guarantee functions, etc. shortcoming.

Three. Contents

In order to overcome the above disadvantages, the utility model provides a fully automatic safe gas cooker with timing cooking, over-temperature automatic flameout, accidental flameout protection, and temperature display. The technical scheme adopted by the utility model to solve its technical problems includes a shell, a furnace head, an air induction pipe, an air valve assembly, an air intake pipe, an ignition switch and a control circuit. The air intake pipe is connected with the air valve assembly, and the air valve assembly passes The air-inducing pipe and the nozzle are connected to the burner, and the ignition switch is installed on the panel of the shell. The gas valve assembly is provided with a solenoid valve. A follow-up thermostat is installed in the center and extends out of the burner.

The control circuit includes a microcomputer controller, an electronic pulser and a power supply, and the microcomputer controller is connected with the ignition switch, the electronic pulser, the power supply, the thermocouple and the ignition needle through wires.

The microcomputer controller is composed of a display, a single-chip microcomputer, a control circuit, an alarm circuit and a detection circuit.

After adopting the above structure, the follow-up thermostat is close to the bottom of the pot, and the double-layer structure of the inner shell can isolate the influence of heat radiation from the surrounding flames, so as to accurately measure the temperature of the bottom of the pot; the cooking temperature and time are controlled in real time by the microcomputer controller , and provides accidental automatic flameout, timing cooking flameout, anti-dry flameout and over-temperature flameout protection functions, alarm function and temperature display function; it has the characteristics of simple structure, convenient operation, safety and reliability.

V. Specific implementation methods

As shown in Fig. 1, the specific embodiment of the utility model full-automatic safety gas cooker, it comprises shell 1, burner head 6, air-inducing pipe 4, gas valve assembly 3, air inlet pipe 2, ignition switch 14 and control circuit, carry out The air pipe 2 is connected with the air valve assembly 3, the air valve assembly 3 is connected to the burner 6 through the air-inducing pipe 4 and the nozzle 5, the ignition switch 14 is installed on the panel of the housing 1, and the air valve assembly 3 is provided with There is a solenoid valve 10, a thermocouple 9 and an ignition needle 8 are fixed on the burner 6, a follow-up temperature controller 7 is installed in the center of the burner 6 and extends out of the burner 6; the control circuit includes a microcomputer Controller 13, electronic pulser 11 and power supply 12, microcomputer controller 13 is connected with ignition switch 14, electronic pulser 11, power supply 12, thermocouple 9 and ignition pin 8 by wire; Described microcomputer controller 13 is controlled by display, Composed of single chip microcomputer, control circuit, alarm circuit and detection circuit.

The working process of the utility model is as follows: when in use, press the ignition switch, the solenoid valve 10 of the gas valve assembly 3 is pushed open by an external force, and the gas enters the furnace from the intake pipe 2 through the gas valve assembly 3, the air induction pipe 4 and the nozzle 5 Head 6 is connected with microcomputer controller 13 and electronic pulser 11 at the same time, so that ignition needle 8 produces sparks to ignite gas. During the normal combustion process, the thermocouple 9 installed on the 6 sides of the burner is fixedly heated to generate an electric potential, so that the circuit of the solenoid valve 10 has a maintenance current to keep the solenoid valve 10 unblocked. In the event of accidental extinguishment during the combustion process, such as wind blowing fire, soup extinguishing fire, etc., the thermocouple 9 will not feel the high temperature so that the solenoid valve 10 has no holding current, and the solenoid valve 10 will automatically close to cut off the gas source to realize the protection function of accidental extinguishment .

When needing to boil regularly, set the time by the microcomputer controller 13, after reaching the set time, the single-chip microcomputer of the microcomputer controller 13 sends an order, cuts off the control circuit and makes the solenoid valve 10 have no current to pass through, and the solenoid valve 10 automatically closes the gas source, Realize timing cooking and flameout. During the regular cooking process, the single-chip microcomputer also detects the temperature of the follow-up thermostat 7, and when the temperature at the bottom of the pot exceeds 130 degrees, the microcomputer controller 13 cuts off the power supply of the electromagnetic valve 10, closes the gas source, and realizes the anti-dry flameout function.

In order to prevent the cooking temperature from being too high, the temperature display protection function of the microcomputer controller 13 can be selected, and the display shows the temperature at the bottom of the pot. When the temperature at the bottom of the pot exceeds a predetermined value, the alarm circuit of the microcomputer controller 13 sends an alarm signal and cuts off the solenoid valve. The power supply is turned off and the gas source is turned off.

When the voltage of the power supply 12 in use is lower than a certain value, the display shows a battery replacement signal.
