DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically extinguishing a fire by extinguishing a fire extinguisher from a fire extinguisher provided in a hood body, for example, when a burner fire ignites oil in a pot during cooking. It is about a range hood that can be made.

[0002]

A conventional range hood of this type is used when a fire extinguisher is mounted on a front panel.
Since the fire extinguisher and its fire detection head and injection nozzle are mounted and positioned on site, there is a problem that it takes time and effort to construct the site.

The present invention has been made to solve such a problem, and requires only a simple mounting operation of mounting a fire extinguisher to a mounting base of a front panel with a fixing bracket.
An object of the present invention is to obtain a range hood that can be installed on a fire extinguisher and its fire detection head and injection nozzle and that can be easily installed on site.

[0004]

A range hood according to the present invention has a box-shaped hood body having at least front and bottom openings, and a position covering the front opening of the hood body from the front opening of the upper space. A front panel detachably mounted, a fire extinguisher mounting base fixed to a portion located in the space behind the front panel, a peephole drilled in the front panel near the fire extinguisher mounting base, A fire extinguisher equipped with a fire detection head and an injection nozzle introduced into the inside of the hood main body by a pressure gauge and a fixed pipe, which are peeped through a peephole, and the fire extinguisher is held in a receiving portion thereof by a tightening band or the like. And a fire extinguisher fixing bracket detachably attached to the fire extinguisher mounting base, and a fixing pipe provided at a receiving portion of the fire extinguisher fixing bracket to fix and position the fixing pipe. It is those with a notch and.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
Referring to FIG. 1 is a longitudinal sectional side view showing a construction state, FIG. 2 is a perspective view of a front panel before being attached to the hood body of FIG. 1 as viewed from the back, and FIG. 3 is a perspective view of a fire extinguisher before being attached to the front panel of FIG. FIG. 4 is a perspective view showing a state before the fire extinguishing device is held on the fixing bracket as shown in FIG.

In FIG. 1, reference numeral 1 denotes a box-shaped hood main body having an open front and lower surface, 2 denotes a space formed on an upper surface 1a of the hood main body 3, 3 denotes a grease filter arranged in the hood main body 1, and 4 denotes a grease filter. A sirocco fan installed behind 3, 5 an exhaust duct of the sirocco fan 4, 6 a front panel detachably mounted at a position covering a front opening of the hood body 1 to a front opening of the space 2, 7 a front panel 6 is a fire extinguisher mounting base fixed to a portion located in the space 2 on the back surface of the fire extinguisher 6 by welding or the like.
Has a screw hole 7b. 8 is a peephole drilled in the front panel 6 near the fire extinguisher mounting base 7, 9 is a pressure gauge 1
0 is a fire extinguisher equipped with a fire detection head and an injection nozzle 12 connected to the fire extinguisher 0 and a fixed pipe 11, and 13 is a fire extinguisher fixing bracket having a fastening band 14 for holding the fire extinguisher 9 and a receiving portion 15, and a fixing piece thereof. 13a has a hole 13b corresponding to the screw hole 7b. 16 is a mounting screw, 17 is a notch provided in the receiving part 15 of the fire extinguisher fixing bracket 13,
When the fire extinguisher 9 is held by the fire extinguisher fixing bracket 13, the fixing position of the fixed pipe 11 is determined. 18 is the hood body 1
Pipe escape portion formed by cutting out the upper surface 1a of the
Denotes a gas stove provided with a gas stove 20, and 21 denotes a top pan.

Next, the operation will be described. When the fire extinguisher 9 is tightened by the tightening band 14, the fire extinguisher 9 is mounted on the receiving portion 15 of the fire extinguisher fixing bracket 13 as shown in FIG. Held on. 3 is attached to the fire extinguisher attachment base 7 of the front panel 6 shown in FIG. In this mounted state, the pressure gauge 10 of the fire extinguisher 9 is oriented and determined in advance so as to match the peephole 8.

After the fire extinguisher 9 is attached to the front panel 6 in a low place, the front panel 6 is attached to the front panel 6 as shown in FIG.
Is attached to the hood body 1 as shown in FIG. At this time, since the fixed pipe 11 is accommodated in the fixed pipe escape portion 18, the fire detection head and the injection nozzle 12 are arranged at a position designed by the fixed pipe 11 so that the fire detection head and the injection nozzle 12 are brought to appropriate positions in advance. The setting positions of the fire detection head and the injection nozzle 12 are as follows.
The relationship between the hood body 1 and the gas stove 19 is designed in advance at an ideal position for detecting and extinguishing a fire. Therefore, since it is only necessary to attach the front panel 6 to the hood body 1, even an amateur can attach and construct the fire extinguisher 9 without error.

[0009]

As described above, according to the present invention, the fire extinguishing device, its fire detection head, and the injection nozzle can be mounted and positioned only by a simple mounting operation of mounting the fire extinguishing device on the mounting base of the front panel with the fixing bracket. The effect that the construction on the site which can be performed becomes easy is acquired.
