Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a tap device for household gas appliances that supplies gas to gas stations such as gas staples and stoves.

Conventional technology In recent years, many household gas appliance plugs have been adopted in which an operating shaft with a valve body housed within the gas body is moved in the υ-axis direction using an operating knob to open and close the gas passage. has been done.

An example of the conventional gas cock device mentioned above will be described below with reference to the drawings.

FIGS. 6 and 7 show a cross section of a conventional gas cock device, and the gas is in a stopped state.

In FIGS. 6 and 7, 1 is an operating knob, and 2 is a guide plate, which fits into the U-shaped receiving plate 5 and fixing plate 6 so as to be able to slide through them, and resists the panel 4. slide in the axial direction. 3 is an operating shaft pressed against the guide plate 2;
is a valve body that is provided on the operating shaft 3 and moves together with it.

The operation of the gas cock device configured as described above will be described below. First, when you press the operation knob 1, the guide plate 2 slides in the axial direction, and the rear part 2b of the kite plate 2
By moving the operating shaft 3 in the axial direction, the valve body 7 opens and gas is supplied.

Problems to be Solved by the Invention However, in the above configuration, after the guide plate 2 is inserted into the U-shaped receiving plate 5 and the fixing plate 6, the U-shaped receiving plate 5 and the fixing plate 6 are screwed together. Since it is necessary to tighten and push the spring 4 into the notch 2C of the guide plate 2, it takes time to assemble, and these parts take up too much space, making it difficult to accommodate them in a normal gas staple etc. It had a point.

Furthermore, since parts with complicated bending shapes (guide plate 2, receiving plate 5, fixing plate 6) are interposed between the operating knob 1 and the operating shaft 30, the stroke of the operating shaft 3 is There was a problem that the gas sealing performance was difficult to stabilize.

Furthermore, since the gas heat power switch depends on the three operating shafts 3.3a and 3b, the heat power can only be switched to three levels: high, medium, and low, allowing for the subtle calorie adjustment necessary for home-cooked dishes. Not only was this not possible, but the number of gas seals increased accordingly, increasing instability and requiring a large number of parts. Furthermore, if the device is operated using a bushing type, even a child can easily operate it, so there is a risk that raw gas may be released due to mischief. Therefore, in recent years, when using this type of operation method, as shown in FIGS. 6 and 7, a lock lever 8 is provided in addition to the firepower adjustment lever 1a, which is configured so that the ignition button cannot be pressed, to improve safety. A locking device was used.

The present invention solves all of these problems, and has a simple structure that reduces assembly time and the number of parts, allows arbitrary adjustment of firepower, and has a simple locking mechanism that can withstand children's mischief. The present invention provides a tap device for household gas appliances that ensures reliable opening and closing operations of gas passages.

Means for Solving the Problems The household gas appliance stopper device of the present invention includes a gas body 1 with a built-in safety valve, and one valve shaft directly connected to the gas body 1 at the axial center position, and a main gas passageway. , pilot gas passage,
The gas body II has a fire power adjustment part, and the front part of the gas body ■ is equipped with an ignition and extinguishing button operation part, a gas passage opening/closing mechanism part, a locking mechanism part, a piezoelectric mechanism part, a low fire power adjustment release mechanism part, and the Ktm By operating the ignition button, the piezoelectric mechanism and the valve stem are simultaneously pressed, and the slide plate of the gas passage opening/closing mechanism is pushed down by the reaction force of the elastic body, and the gas passage is fixed at the "open" position. Only, you can set the desired firepower by moving the firepower adjustment lever, and then
When you press the fire extinguishing button to extinguish the fire, a part of the protrusion on the fire extinguishing button lifts one end of the fffJ slide plate.
Due to the reaction force of the elastic body installed inside the gas body II, the valve stem protrudes and closes the gas passage, and at the same time, when the fire power adjustment lever is in the weak position, the fire extinguishing operation and return lever are also pressed at the same time. It is equipped with a mechanism that allows it to return to a strong firepower state.

Function: When the ignition button is pressed, the operating shaft moves in the axial direction by pressing the guide tube attached to the tip of the valve stem, and the slide plate provided at the top of the guide tube moves due to the reaction force of the elastic body. Pushed down and fixed between gas passages. At this time, the piezoelectric lever of the piezoelectric mechanism is also pressed at the lower end of the ignition button to generate electrical energy. After that, use the firepower adjustment lever as desired. When extinguishing a fire, by pressing the extinguishing button, a part of the protruding part of the extinguishing button lifts one end of the slide plate, and the reaction force of the elastic body installed inside the gas body and mouth causes the valve stem to protrude and release the gas. becomes closed.

Furthermore, when the fire power adjustment lever is set to low, the return lever is simultaneously pressed by the fire extinguishing button and the firepower is turned off! :Become. After extinguishing the fire, when the fire power adjustment lever is moved to the lock position, the tip of the lock lever faces between the valve body attachment and the guide tube, so even if the ignition button is pressed, the guide tube hits the tip of the lock lever and cannot be pushed.
