Description

Timing flameout protection gas valve structure

This creation is about a flame-out protection gas valve structure; in particular, it is about a time-out flame protection gas valve structure that can forcibly shut off the supply gas in use.

According to the conventional gas stove gas valve structure, it mainly includes: a furnace head with an inner and outer ring furnace tube, a connected gas valve set at the inner and outer ring furnace tubes of the furnace head, and a set of The supply of total gas at the gas valve, where the gas valve includes an intake passage for supplying the inflow of total gas, a gas chamber connected to the intake passage and used for a closed housing, and It is connected to the gas chamber and is used as an outlet channel for the split gas that has flowed through the closure to flow out toward the outside of the gas valve.

When in use, the rotary knob will turn to drive the closure to follow the rotation, so that the gas chamber can be connected to the outlet channel. At this time, the total supply gas will flow through the inlet channel and the gas in sequence. The chamber, the closure and the gas outlet channel then flow into the inner and outer ring furnace tube, so that the inner and outer ring furnace surface of the furnace head is provided with a supply of split gas, thereby achieving the purpose of ignition and combustion.

Although the above creative projects can achieve the original creation goals, they are highly praised by the industry and general operators. Continuous innovation and breakthroughs in technology have caused applicants to work harder to research and improve, and make them perfect and practical; in addition, the creators have undergone countless updates of experimental tests and summarized consumers’ practical and operational responses. , Found that the following problems still need to be further improved:

Since ordinary housewives would switch the fire to a low fire before simmering when simmering, at this time, if there is an urgent need to deal with urgent matters, they will subjectively think that simmering will cost longer Time, so that you can leave the kitchen immediately and then rush to handle other urgent matters. Once the urgent matters take a long time and require concentration, they tend to ignore the stuffy ingredients in the kitchen due to forgetfulness. The accidental occurrence of fire after the stuffy pan is completely dry is a big trouble.

Therefore, how to develop a safety protection that can forcibly shut off the gas supply during use is a technical issue that the industry needs to solve first.

The main content of the timing flameout protection gas valve structure of this creation is to provide a flow control device installed at the gas outlet channel of the switch valve group, and the flow control device is in communication with the timing device, using the timing device The set time control is used to start the flow control device to produce the corresponding movement, as a priority to forcibly cut off the corresponding split gas required to flow through the gas outlet channel and the fire source located at the side of the thermocouple. So that the thermocouple will not be directly burned by the fire source, and after the thermocouple is no longer energized, the valve plate will be pressed against the peripheral side of the valve port to block the external supply of total gas from continuing to flow into the switch The basis of the gas chamber of the valve group is to form that once the set time is up, the split gas will be forced to close and then the supply The total gas should be used, and as soon as the set time is up or the burner is accidentally turned off, the total gas supply in use is immediately forced to be completely shut down. The safety function of double insurance is an advanced effect.

Another object of the present invention is to use the set time of the timing device to control the start of the flow control device to produce the corresponding movement, as a priority to force cut off the corresponding flow through the outlet channel and located at the side of the thermocouple The shunt gas required by the fire source. As a result, the use time of the timer device is short, so that it consumes a relatively small amount of electricity, which can make the battery life longer and effectively reduce the number of battery replacements And inconvenient operation, which increases the convenience of consumers is another effect.

When the flame of the inner flame hole 601 in the inner ring surface 60 of the burner 6 suffers from accidental ignition, the thermocouple 35 installed on the side of the inner flame hole 601 will no longer be affected by the inner flame hole 601. The flame burns directly, so that the thermocouple 35 does not generate a micro current (or micro voltage) and the solenoid valve 30 cannot be excited, so that the valve plate 32 will withstand the rebound force from the spring 33 and the intake passage The gas pressure of the total supply gas in 10 can force the valve plate 32 to actually abut the valve port 11 at the intake passage 10, so as to prevent the total supply gas from flowing into the switch valve group 1. Inside the gas chamber 12, the inner and outer ring surfaces 60 and 61 of the burner 6 and the main flame tube 7 are fully flame-out safety protection and effectively prevent accidents of carbon monoxide poisoning caused by gas leakage.

When you want to cook with a low fire for 1 hour, you only need to adjust the timing device 4 to a predetermined time, and when the set time of the timing device 4 is up, the timing device 4 will send a signal to the flow control device At two locations, the second solenoid valve 25 of the flow control device 2 is excited to drive the rocker 251 and the leak-proof member 252 on it to move until one end of the leak-proof member 252 abuts against the inlet flow passage 200 circumference side, in order to surely block the split gas from the intake runner 200 that is going to flow into the gas cavity 210, and make the inner ring 62 of the burner 6 no longer flow into the split gas, relatively The ground will cause the inner flame hole 601 of the inner ring surface 60 to form a forced flameout due to the supply of no split gas. At the same time, it also makes the inner flame hole 60 installed The thermocouple 35 on the side 1 is no longer directly burned by the flame formed by the inner flame hole 601, so that the thermocouple 35 does not generate micro current (or micro voltage) and the solenoid valve 30 cannot be continuously excited.
