JPH04103162U - Fire extinguishing system that also serves as a smoke exhaust hood - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to obtain a device for extinguishing flames caused by ignition of oil for frying, which also serves as a smoke exhaust hood. [Structure] A cover member having an opening/closing lid is attached to the exhaust pipe via a fuse with the opening/closing lid open.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was developed to extinguish the flames caused by the oil igniting when frying food using oil. It is related to fire extinguishing equipment used for It was made so that it could be done.

0002

[Conventional technology]

When frying food using oil, the flame on the stove may catch on fire and spread to the oil. There is a risk of a fire. In such cases, if you pour water on it, it will warp and the flame will spread. Therefore, to extinguish a fire, it is necessary to cover the area above the stove and the pot to isolate it from the outside air. For this reason, bag-shaped fire extinguishers made of nonflammable cloth are also on sale.

0003

[Problem that the idea aims to solve]

However, if the above oil ignites, the flames will reach a considerable height, so do not It is extremely difficult to cover with cloth, etc., and it can be dangerous and even more difficult, especially if it is discovered late. It becomes difficult.

0004

[Means to solve the problem]

On the other hand, this idea is always suspended like an umbrella over the stove, and if the oil ignites, The hood automatically falls down and covers the stove top, and in normal times it is used as a general smoke exhaust hood. We have developed a fire extinguishing system that can be used in

[0005]

[Example of idea]

To explain the embodiment of this invention with reference to the drawings, in Fig. 1, 1 is this invention. The covering member is the main part of the A fire-resistant cloth, etc. is used to cover the round or square edge frame 2 and the small diameter top frame 3. It is made into a conical shape with an open top and bottom by covering it with a soft fireproof sheet 4. At the same time, an opening/closing lid 5 made of a metal plate is always connected to the top hole through a spring 6. It is designed to be closed.

[0006] Next, 7 is an exhaust pipe whose tip leads to the outside, and whose base end is located directly above the stove. The cover member 1 is attached to the base end of the exhaust pipe 7. It is inserted and installed. In this case, the opening/closing lid 5 is opened upward in advance against the spring 6. A collar 8 is loosely inserted into the base end of the exhaust pipe 7 to support the top frame 3. The collar 8 is supported by a U-shaped fuse 9 whose one end is fixed to the exhaust pipe 7. There is. This fuse 9 is the same as that used in well-known fire sprinklers. It is also made of a material that melts at low temperatures, such as a cadmium alloy.

[0007]

[Effect of the idea]

This idea has the above-mentioned structure, and the smoke and steam generated when cooking on the stove 10. The air is collected in the cone-shaped cover member 1 located directly above it, passes through the exhaust pipe 7, and exits the door. In other words, under normal conditions, the cover member 1 serves as a smoke exhaust hood. However, if the oil in the pot on the stove ignites and the flame rises high, the heat of the fire will As the fuse 9 melts, the collar 8 falls off and the entire cover member 1 is removed. At the same time, the opening/closing lid 5 blocked the top hole by the spring 6, and fell in this state. In the cover member 1, the edge frame 2 first surrounds the periphery of the stove 10, and then the top frame 3 surrounds the periphery of the stove 10. Due to its own weight, the whole body collapses and attaches to the upper edge of the pot, enveloping the flame, so the fire The flames are quickly extinguished.

[0008] The frame frame 2 is made of hard wire, etc. so that it will follow the unevenness of the place it falls when it falls. Instead, it should have a flexible structure like a rosary.

[0009] As described above, this invention has a structure in which the covering member 1 falls in response to ignition. This prevents fires and burns to the user, and also prevents smoke exhaust hoods during normal times. It is extremely efficient.
