TW200821507A - Switch-free and energy-saving control method for gas stove electronic ignition device - Google Patents

Abstract

The invention provides a control method for gas stove electronic ignition device to avoid the use of micro switches or button switches to improve the drawbacks, the assembling and adjustment difficulty and malfunction during operation, resulted from adopting switches, and also to save material cost for this kind of switches, conducting wires and connectors and working-hour cost for assembling and adjusting. When the gas stove knob is started, the inner pull rod of the safety valve assembled with the permanent magnet is close to the solenoid coil and the electromagnetic field is changed to generate the voltage signal. The voltage signal is amplified and performed by waveform process to start the electronic igniter (high-pressure igniter). The intermittent signal is used to drive the electronic igniter to save the electric energy required for the operation of electronic igniter under the condition that the gas pipe is longer. The control method of automatically stopping ignition immediately when ignition is accomplished is to save the electric energy required for each ignition. The control system also allows the user to let go hand right away once the knob is operated to specific position (usually rotation for 90 degrees). The control system would automatically ignite continuously until the fire is on or the time is up. Thus, it is no need for the user to keep pushing the knob.

When the distance between the electromagnetic coil and the magnetic field is changed, the invention changes the line-flux density, and the electric human principle of inducing the electric potential on the coil, the new user uses the thief network to open the gas channel. Pushing the lever of the safety valve internal & long-time magnet close to the electromagnetic coil causes the electromagnetic coil to generate an electromotive force. The signal is applied to the electronic circuit for amplification and waveform processing to drive the electronic igniter to generate sewing money to perform gas furnace ignition. Therefore, this hair reduction and electronic circuit # is still. ^ am The invention applies the automatic control engineering coffee road control (four) system, so that only need to operate the knob to the positioning (usually 9 degrees of rotation) can be released when the ignition, the control system of the present invention will perform automatic ignition until the fire domain Should be based on the fire has been detected ^ or 4 200821507 The end of the timing will stop the ignition immediately. The flame sensor of the present invention adopts the vacuum tube principle of electronics, and is insulated and insulated from each other by a slit between the burners of the flame sensor, and the electrodes are combined with different electrodes, and the flame induction|§ is positively charged. The anode (such as 〇 )), the burner is a negatively charged cathode (Cathode), the temperature of the ϊ fire will cause the surface of the burner to produce free electricity =, the high temperature of the flame will also let the air around the slit The rapid expansion is similar to the vacuum state, in which the free electrons are attracted by the anode of the flame sensor to form an electron beam flowing through the slit to the flame sensor, so that the flame sensor can sense the current due to the flame. [Prior Art] Gas furnaces using electronic ignition H (also known as high-voltage generators or pulse igniters) use micro-switches or push-button switches to interlock with the gas channel start-up knobs to connect the switches when the gas is turned on. The point is closed, the current of the battery is passed to drive the ignition, and the high-voltage wire is generated to perform the gas ignition. The driving signal of the electronic igniter between the rotating shafts by the user is continuous (the working period is 1%).

The use of micro switch or button switch will have the following shortcomings: (1) In the use of the soup due to the infusion of soup into the contact, the switch function is disabled, (2) each furnace: install micro switch or push button switch and must have connecting wires and connectors , all need material 2 wire, cost, and increase the age, (1) gastone · miscellaneous (four) both open tile 4 money linked to micro-motion _ or according to the double task, so the structure is more secret, and the pure __ makes the micro-motion _ Or according to the bad machine, the reward will result in no money transfer. (4) Function loss = In addition, if the gas source (gas barrel or natural gas switch) is long, the gas source needs to reach the ignition (gas burner) for a period of time. Time, at this time, using the method of sending out a high dust signal to ignite will waste the battery in vain = the trouble of replacing the battery and increasing the cost of the battery. , b W into the current use of the most gas furnace safety valve of the knowledge of the use of the (T--ler) principle of the sensor 'the sensor dare to point to control An: 5 200821507 __) mouth this user mother When igniting, operate the knob to the position (the speed is turned 90 degrees), you can't let go, you have to wait for a few seconds after the fire is on. (Not fixed time I let go, so the turn of the fairy is uncomfortable and * convenient, the igniter will be in vain Waste of electricity_electric energy. [Summary of the invention] The present invention provides a method for watt-free electronic 敎 (4) to achieve ▲ exempt micro-switch or push-switch to improve installation and adjustment difficulties caused by switches

And, easy, the shortcomings, and can save the cost of the switch and its wire and joint material cost t installed; (2) to drive the electronic igniter with intermittent signal, under the condition of the tile two roads, can save The ignition of the electric energy is wasted; (1) the ignition control mode is automatically stopped to save the energy of each ignition; (4) When the ignition is performed, the user can operate the knob to position (usually rotated 90 degrees) and then let go. The invention is implemented in an automatic ignition system to increase the comfort of the ignition of the gas furnace.

The present invention is a gas furnace safety crucible structure of the "structure and control method of a gas-fired safety valve with power saving performance" (the invention No. 246577) which is patented by Gufa Day, when the gas furnace knob opens the gas. When the action of pressing down, the inside of the safety cymbal will be combined with the permanent magnet to pull the lion near the electromagnetic coil, and at this time, the electromagnetic field will change due to the change of the electromagnetic field, and the magnetic flux density of the magnetic coil will be increased from small to large, and the signal will be induced. The electronic circuit is magnetized and the wave is oscillating (such as the schematic) to activate the igniter to avoid the difficulty of installation adjustment caused by the currently used micro switch or button switch, and to avoid the influx of soup water due to cooking. The contact causes the failure of the switch function, and can save the cost of the switch and its wires and contacts and the labor cost of installation. Since the high _ fire pulse signal generated by the electronic igniter is very high (about 10,000 times per second), the way of igniting the igniting is only to record the electric energy, but not to increase the ignition efficiency; therefore, the present invention uses intermittent Type signal (duration cycle about 20%) 6 200821507 The pipeline is long and secret, Navas is always rotating ^ Invented to allow the user to operate the knob to the position each time the ignition is started (the current is the intermittent ignition, until the fire It has been scheduled to end at the end of the time, and the convenience is 22, which can increase the comfort of the user when operating the gas stove and ignite the lion. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _亍 __ running time (about the number of hours, the above m2 can be phased by the thermocouple type sensing 11, you have to wait for more == 费手松_' can therefore save the present invention every ignition operation [implementation 】 Efficacy, method and its structural composition, and the resulting exemplified figure of the knife.
