Description

Extension bar folding device for gas fire extinguisher

The present invention relates to an extension bar folding device for an automatic fire extinguisher for a gas range. More specifically, the extension bar including the injection nozzle is maintained in one side of a cabinet in which a bowl or the like is housed in a normal case in which no fire or overheating occurs. When the check valve is operated due to the fire or overheating, and the extinguishing agent in the extinguisher container is discharged at a predetermined pressure, an extension bar having an antenna shape protrudes to the outside through a through hole formed at one side of the storage cabinet to extinguish the fire. .

In other words, in order to prevent contamination by steam or smoke generated during cooking of food, it is possible to maintain the state of being placed to one side in the storage box in which the extension bar is folded and the container is normally folded. In addition, the shape of the extension bar can be prevented from being deformed or damaged at all around the user's handling area. The check valve is activated due to fire or overheating, and the extinguishing agent in the extinguisher container is discharged to a predetermined pressure. The extension bar in the folded state is projected outward through the through hole formed in one side of the cabinet (that is, it is extended by the ejection pressure of the extinguishing agent) so that the extinguishing agent is correctly positioned in the upper part of the center of the gas range. It is invented to be able to spray.

Various automatic fire extinguishers for a conventional gas range are already known.

However, most automatic fire extinguishers are equipped with a fire extinguisher container and a check valve in a hood at the top of the countertop, and a spray nozzle is installed at the other end of an extension bar having one end fixed to one side of the cabinet at the lower end of the hood. Between the and the spray nozzles, a conduit is extended so that the extinguishing agent in the container reaches the spray nozzles, and a hose link and a predetermined link with a wire cable assembled at the end of the extension bar from the fire extinguisher operating lever so that the fire extinguisher is activated when a fire is detected. The spring is installed to maintain the tension of the fire extinguisher, and the plug and the pressing plate are configured to control the discharge of the extinguishing agent in the fire extinguisher container.

That is, in the conventional gas stove automatic fire extinguishing device, an extension bar having a predetermined length protrudes from one side of the cabinet to reach the center of the gas range, and a spray nozzle is installed at the free end of the extension bar. As such, the extension bar and the injection nozzle occupy a part of the cooking space formed at the upper portion of the gas range, and thus, the extension bar and the nozzle may be jammed when cooking. When the shape of the extension bar is deformed or damaged at all times around the user's handling area, water vapor, odor, and surrounding dust generated from food are solidified by sticking to each component due to long-term use of the gas range. It interferes with normal operation and does not function as an automatic fire extinguishing device. There is a problem such.

Accordingly, the present applicant has developed an automatic fire extinguishing device for a gas range which can solve the above problems and filed it as a patent application No. 16117 in 1998, which is installed in a form in which a fire extinguisher container is placed perpendicular to the bottom side of the hood. The nozzle unit including the container is rotatably installed in a fixing means for fixing the container to a wall or the like so that the user can rotate the nozzle part to the center of the gas range.

However, in such a configuration, since the fire extinguisher container is installed vertically on the wall, the space above the sink cannot be used smoothly, such as the container being stuck when the object needed in the kitchen is installed on the wall. Since the nozzle can be rotated in the fixing means together with the additional container, the nozzle part may become difficult to cook, and may be rotated to one side. Therefore, when the fire actually occurs, there is a problem such as not being able to function as a fire extinguisher. .

The present invention has been made in order to solve the above-mentioned problems, and the extension bar itself is formed in the shape of an antenna to maintain the state of being placed in one side of the cabinet in which the container is accommodated in the extension bar is normally folded state of the food It is possible to prevent contamination by surrounding dust, including steam, odor and smoke generated during cooking, and to maximize the use of the cooking space, as well as to deform or break the extension bar around the user's handling area. It is an object of the present invention to provide an extension bar folding device for an automatic fire extinguisher for a gas range, which can be prevented.

Another object of the present invention, when the check valve is operated due to the fire or overheating caused by the ejection pressure of the extinguishing agent filled in the fire extinguisher container is extended to the outside through the through-hole formed in one side of the storage cabinet spraying The present invention provides an extension bar folding device for an automatic fire extinguisher for a gas range, in which a fire extinguishing agent can be injected while a nozzle is accurately positioned above the center of the gas range.

The object of the present invention is installed on the top of the gas range, when the temperature detected around the gas range detected by the temperature sensor is detected to rise above a predetermined temperature to operate the gas circuit breaker through the control panel and generates an alarm sound, In the automatic fire extinguishing device of the gas range, the fire extinguisher can be extinguished by the operation of the check valve to inject the extinguishing agent filled in the fire extinguisher container through the conduit and the extension bar to penetrate the inside and outside of the storage cabinet to extinguish the fire. Several tubes having a circular or quadrangular shape are sequentially inserted to form an antenna shape in which the length thereof can be varied, and both ends of the tubes are formed to have a protrusion and a protrusion which are bent outward and inward, respectively, so that they are not separated from each other. And the extension bar is located at the bottom of the cabinet. A fixture is provided to fix the outermost body of the cabinet so that it is normally settled in the cabinet in a state of maintaining a flat state, and the one end of the extension bar and the spray nozzle are adjacent to one side wall of the cabinet. It can be achieved by forming a through hole, and by installing a shielding film that can be damaged even at a small pressure around the outer periphery of the through hole.

Therefore, in general, the extension bar can be folded and settled in the cabinet, thereby preventing contamination by water vapor, odor, smoke and dust generated during cooking of the food, and making the most of the cooking space located above the gas range. When the extinguishing agent in the extinguisher container is discharged due to fire or overheating, the extension bar having an antenna shape is automatically unfolded so that the injection nozzle at the end of the gas stove Because it is located exactly above the center of the fire will not interfere with the fire suppression.

(A)-(c) of 4 show some perspective views of the tubes forming the extension bar.

According to this, the gas circuit breaker 4 is opened through the control panel 3 when the temperature around the gas range detected by the temperature sensor 2 is installed at the upper portion of the gas range 1 and is detected to have risen above a predetermined temperature. Activates, generates an alarm sound, and actuates the check valve (5) to inject the extinguishing agent filled in the fire extinguisher container (6) through the conduit (8) and the extension bar (9) installed to penetrate the inside and outside of the cabinet (7). In the automatic fire extinguishing device of the gas range that can be fired by the nozzle 10 to extinguish the fire,

The extension bar 9 is formed in the shape of an antenna that can be varied in length by sequentially inserting several tube 90 having a predetermined length, the both ends of the tube 90, respectively, the obstacles are bent to the outside and inward To form the portion 91 and the support protrusion 92 so as not to be separated from each other,

On the inside of the cabinet (7) is provided with a fixture (11) for fixing the outermost tube to maintain the state that is normally placed in the cabinet while the extension bar (9) is level with the bottom surface, ,

A through hole 71 is formed at a portion of one side wall 70 of the cabinet 7 where the one end of the extension bar 9 and the injection nozzle 10 are adjacent to each other.

The outer periphery of the through-hole 71 is characterized in that by installing a shielding film 12 made of a material that can be damaged even at a small pressure.

At this time, the tubular body 90 may be used by selecting any one whose cross section has a circular or rectangular and triangular shape as shown in (a)-(c) of FIG. 4, and the tubular bodies 90 An oilless ring 93 may be installed as shown in FIG. 3 to reduce the friction force between the tubes.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the fire extinguisher container 6 having the check valve 5 is installed inside the hood 13 installed above the gas range 1, and the temperature sensor 2 is located above the gas range 1. The gas circuit breaker 4 is installed above the gas leakage breaker on the gas pipe, and the control panel 3 is installed inside or outside the storage cabinet 7, and the fire extinguisher container 6 and the extension bar 9 are provided. Conduit (8) connecting between and the extension bar (9) to which the present invention is applied is also installed to be located in the cabinet (7) normally.

That is, the extension bar 9 is formed by inserting a plurality of tube bodies 90 having a predetermined length in order to have an antenna shape, the length of which can be varied, and at both ends of the tube bodies 90 to the outside and the inside, respectively. By forming the engaging protrusion 91 and the supporting protrusion 92 to be bent so as not to be separated from each other, the extension bar 9 itself without protruding the extension bar 9 to the outside of the cabinet 7 as in the prior art. To fold sequentially will be placed inside the cabinet (7).

In this case, one end of the extension bar (9) connected to the conduit (8) side is installed to be parallel to the bottom surface inside the cabinet (7) through the fixture 11, the extension bar (9) itself and the antenna Since it is composed of several tubes 90, the fastener 11 is fixed only the outermost tube of the extension bar (9) so that other tubes can be freely sliding movement.

Meanwhile, the tubular bodies 90 constituting the extension bar 9 may be extruded to have a circular, square or triangular shape as shown in FIGS. 4A to 4C. If the tube 90 is rotated with each other, when the extension bar 9 is extended due to the actual fire, there is a risk that the injection nozzle 10 may not be accurately positioned toward the lower portion, so that the extrusion 90 to have a rectangular or triangular shape It is good to let.

Of course, even though the tubular body 90 is formed in a circular shape, since the injection nozzle 10 installed at the free end of the extension bar 9 has a certain weight, the injection nozzle 10 is automatically directed downward, In the case that the injection nozzle 10 does not face downward due to the friction force generated between the pipe bodies 90 or the discharge pressure of the extinguishing agent, the cross section of the pipe body 90 is extruded to have a rectangular or triangular shape. Is good.

In addition, the tube bodies 90 may be molded to have an elliptical cross section, or may be used by forming grooves in a longitudinal direction on a circular shape.

In addition, since both end portions of the tubular bodies 90 are formed to be bent outwardly and inwardly, the engaging protrusion 91 and the supporting protrusion 92 are formed so that the engaging protrusion 91 and the supporting protrusion 92 are adjacent to the inner circumferential surface of the tubular body or As the surface is in contact with the outer circumferential surface, the airtightness is kept to a certain degree by the metal friction pressure, and when the extinguishing agent is discharged due to the fire, the leak is prevented to some extent. When the oilless ring 93 is installed between the pipe bodies 90, the airtightness can be improved while further reducing the friction between the pipe bodies.

On the other hand, the extension bar (9) and the spray nozzle (10), which is normally held in the cabinet (7) is normally exposed to the outside of the cabinet (7) by the discharge pressure of the extinguishing agent in the event of a fire The through-holes 71 are formed in one side wall 70 of the cabinet 7, and when such a through-holes 71 are placed therein, the steam holes, odors, and smoke generated during cooking of the foods through the through-holes are provided. Since dust or the like may be introduced to contaminate the inside of the cabinet 7 and the extension bar 9, a screen 12 is disposed around the outside of the through hole 71.

At this time, by selecting and installing a paper, such as a material that can be damaged even at a low pressure to the screen 12, the fire extinguishing agent filled in the fire extinguisher container (6) by operating the check valve (5) due to fire or overheating When the inflow to the extension bar (9) through the conduit (8) is extended to the conduit (8) constituting the extension bar (9) by the ejection pressure of the extinguishing agent at a rate corresponding to the ejection pressure is extended to the extension bar (9) Free end of the) and the injection nozzle 10 can tear the screening film 12 installed in the through-hole 71 of the cabinet 7 can easily protrude to the outside.

As such, the entire length of the extension bar 9 protruding to the outside of the storage cabinet 7 may have a length such that the injection nozzle 10 can be positioned above the center of the gas range 1 as in the prior art. This properly sets the length of the tube bodies 90 that are folded by means, and in the state in which the extension bar 9 is coupled to the conduit 8, the extension bar 9 is connected to the cabinet 7 through the fixture 11. When the extension bar 9 is forcibly extended in the state in which the extension bar 9 is completely extended, the injection nozzle 10 is accurately positioned above the center of the gas range 1, and then the fixture 11 is fixed. What is necessary is just to fix the extension bar 9 in the storage cabinet 7 using.

As described above, according to the present invention, since the extension bar itself is configured to be foldable like an antenna, the extension bar can be folded and placed in the cabinet in the usual time, so that steam, odor, smoke, and dust generated when cooking food. It is possible to prevent contamination by, etc., and to maximize the use of the cooking space existing in the upper portion of the gas range, as well as to prevent deformation or damage of the shape of the extension bar. Therefore, when the extinguishing agent in the fire extinguisher container is discharged, the extension bar having an antenna shape is automatically unfolded so that the spray nozzle at the end is located exactly above the center of the gas range, so that it does not affect the fire suppression. It can be.
