Description

[Detailed Description of the Invention] The present invention relates to a gas stove that has an automatic fire extinguishing device that automatically extinguishes the gas burner when an object to be burnt, such as a pot, placed on the trivet of the gas stove is removed.

With conventional gas stoves, even if you remove the pot or other object placed on the trivet, the gas will not be extinguished until the main gas supply is shut off by turning the trivet knob by hand. The gas had to be extinguished manually each time.
For this reason, in households that are busy with cooking, etc., even if the pot etc. is removed from the top of the trivet, there is a time interval before the next manual extinguishing action is taken, and during this time the gas remains lit, which is a hassle. In addition, it is dangerous to ignite gas without an object to be burned on the trivet, and it is extremely uneconomical because unnecessary gas is burned. Furthermore,
Great consideration was also required in terms of safety, including whether the gas was completely extinguished.

The present invention was created in order to eliminate the various drawbacks of conventional gas stoves as described above.
The purpose of this is to provide a device that automatically turns the pot knob and automatically extinguishes the gas burner, without requiring any manual action, at the same time as removing objects to be burnt, such as pots, from the top of the gas stove trivet. Our goal is to provide gas stoves that are safe, convenient, and highly economical.

An embodiment of the present invention will be described below with reference to the attached drawings.

In the figure, reference numeral 1 is the burner body, which has a gas jet hole 2 in its upper surface.The burner body 1, which is housed inside the stove body 3, has a circular cylindrical shape when viewed from above. A circular space is formed at the center of the dovetail. In the center of the space located at the center of the burner body 1, there is provided a vertically movable lifting rod 6 that projects from the top surface of a trivet 5 installed in the stove soup saucer 4 above the burner body.
The lower end of the lifting rod 6 is pivotally connected 8 to the end of the actuating rod 7 through a suitable shaft. An elastic body 9 made of an appropriate coil spring or the like is protruded from the actuating rod 7 near the pivot 8, and the actuating rod 10 is pivotally connected to the actuating rod 10 by an appropriate axis near the elastic body. A support rod 11 that supports the rod is provided in a protruding manner, and when placing a pot or other object to be roasted (not shown) on the trivet or removing it, it is possible to As shown, as the lifting rod 6 moves up and down, the operating rod end 12 also moves up and down as shown by arrows b and b'.

The end 12 of the operating rod, which moves upward in accordance with the downward movement of the lift rod 6, is brought into strong contact with the lower end surface of the overall disk-shaped knock-clock device plate 13 by the action of the elastic body 9. The knock-clock device plate 13 has a locking hole 14 into which the end of the operating rod is fitted and locked, and a square prism-shaped connecting rod 17 is inserted, which is connected to a spiral spring body 16 fixed and locked to a protrusion 15 protruding from the inside of the stove body. At the center of the knock-clock device plate is a knock clock 1, which operates in conjunction with a normal piezoelectric ignition device ○ and a gas opening and closing device ○.
The shaft 19 of the 8 is fixed integrally to the shaft 18.
The clock device plate 13 also rotates in accordance with the rotation of the clock. This is as shown in FIG.
The cock and the cock-clock device plate are adapted to rotate integrally through 90° or more in the direction indicated by the arrow c.

Therefore, when the operating rod end 12 is moved upward and is strongly abutted against the lower end surface of the locking device plate 13, when the rod 18 is twisted, the locking device plate 13 is also rotated at the same time, and the locking device plate 13 is engaged. When the locking hole 14 is rotated to the position of the actuating rod end, the actuating rod end 12 is firmly fitted into the locking hole 14 and locked. In this case, gas is released from the gas opening/closing device in accordance with the rotation of the cock 18, and at the same time, the piezoelectric ignition device is also activated, and the ejected gas from the spark nozzle ○2 is ignited from its discharge portion ○c, and further. This is the same as conventional devices in that it is ignited by gas ejected from the gas ejection hole of the burner body through the gas conduit ◯◯.

In the gas stove of the present invention configured in this manner, when the object to be baked such as a pot receives heat and is removed from the trivet, the elevating rod 6 is raised by the force of the elastic body 9 and returned to its original position. At the same time, the operating rod end 12 descends and disengages from the locking hole 14 of the lock clock device plate, so the lock clock device plate 13 and the lock 18 are also rotated back to their original states by the action of the mainspring spring body 16. At the same time, the gas supply from the gas switch device to the gas burner body is stopped, and the fire in the gas burner body is automatically extinguished. In addition, in this invention,
Since the shaft rod 19 that fixes the pot and the pot plate as one unit is configured to be able to be pushed and pulled in the direction of the arrow d to d', the object to be burnt can be left on the pot while it is being placed on the pot. If you want to extinguish a gas fire, pull the entire pot toward you and release your hand from the pot, and the end of the actuating rod will disengage from the locking hole 14, extinguishing the fire in the gas burner body using the same process as above. be able to. In this case, the rectangular prism connecting rod 17, which is inserted through the clock device plate and connected to the mainspring spring body 16, is in a state where it can pierce the clock device plate.

Furthermore, the present invention has a fixed rod 20 protruding from inside the gas stove main body on the extension line of the end of the operating rod, and moves the lock and the lock device plate toward the front completely independently of the movement of the lifting rod and the end of the operating rod. It is also possible to insert and lock the fixing rod into the locking hole of the lock clock device plate by pulling the rod, rotating it, and igniting it.

As described above, the gas stove of the present invention can automatically extinguish the gas at the same time as the object to be burnt, such as a pot, is removed from the top of the trivet, so that unnecessary gas is burned even after the object to be burnt is removed from the top of the trivet, unlike conventional methods. This completely eliminates the extremely uneconomical problem of leaving the food on, and provides extremely safe, convenient, and practical effects even during busy times such as when cooking.
