Description

M263471 $, Creation Instructions (1) [Technical Field to which the New Type belongs] A safety control device with timing, display and inviter gas stove, 1 set ;: =; "magnetic reading home control unit and display interface, = to include The setting panel, the gas stove device of the central user's all-girls. | Back for [prior art] When the clock is in general, because of forgetting the relationship, most of the germination uses the gas time method. The time to enter the digital electronics is strictly affected and a new generation Several of these devices are therefore convenient. Therefore, the devices can be made independently, which allows the built-in timing of the new gas stove to be built. The structure of this creative device is almost always used to cook gas and often creates a research and development furnace. In recent years, the fashion design has been called for. It ca n’t be too long. At present, most homes are built in furnaces, and they are generally installed in existing existing homes. The structure and structure of new stoves are not considered high. When adjusting the timing, there is a general reason for the technology of the sub-generation, but the mechanical and can not only be applied to the sub. In terms of the timing of the home is still straight. For the purpose of standardization, gas stove users temporarily leave the food to burn or even cause a fire-type gas stove timing. For a long time, in the past, given the progress of mechanical fixing, its timing device has been set timing The method has the lack of timing accuracy to count in seconds. In the new gas furnace, most of the furnaces cannot be installed and used safely because of the inability to use the technology. The structure of the purchased Hai Hai device is only suitable for other general domestic gas stoves. The key to the safety gas stove on the surface is to use the thermocouple with high consistency.

Page 6 M263471 4. Creation instructions (3)) and warning circuit (a6), the above solenoid valve output circuit (al) and fire cutout circuit (a 2) are connected to a solenoid valve (c). For ordinary housewives who need to stew, and the personnel can't stand by the fireside all the time, 'This creative device can meet the user's needs, and when the set time arrives', the gas will be automatically cut off, and there will be a warning sound. Call the user to inform the set time, and ask them to come back and check the cooking situation. [Embodiment] As shown in the action block diagram of the third figure, after this creative operation, it enters the timing program 'starting time counting, and when the set time is reached, it will issue an instruction via the solenoid valve output circuit (al) and the fire circuit (a2). Make the solenoid valve (C) cut off the gas, and then the safety detection circuit (a5) detects whether there is still a fire source? If it is negative, the action is ended. If it is, the gas is cut off again. In this creation, after the gas furnace is cut off, the power detection circuit (A 1) detects whether the fire has been cut off. It directly detects whether the current generated by the thermocouple (B) continues to exist (indicating that the fire is still on). , And through the voltage: large circuit (A 3) to detect whether there is still current output, if there is a fire cut off action again, until a certain voltage value is not detected to determine that there is no fire source. ‘According to this’, this creative device uses the setting key, the central person's T · ^ 1 towel.
