BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings.

FIGS. 1 to 3 show a range hood device 1 according to a first embodiment of the present invention. The range hood device 1 according to this embodiment is arranged above a heating device 2. Range hood body 10 and this range hood body 1
0 is attached to the smoke collector 11, and the smoke collector 11 is a hanging cabinet 12 in the upper part of the heating device 2.
Is attached to the lower surface of the via a fastening means such as a screw.

The smoke collector 11 is made of a non-combustible material such as calcium silicate plate that meets the requirements of the Fire Service Act, and the top plate 1
1a and both side plates 11 connected to both sides of the top plate 11a
b, 11b and the back plate 11c are formed in a generally concave shape in cross section, and the frontage dimension D thereof has substantially the same frontage dimension as that of the hanging cabinet 12, and the depth dimension is also 12 Is formed to have a depth dimension substantially the same as the depth dimension.

On the other hand, the range hood main body 10 has a lower surface opened, and an intake fan and a lighting device (not shown) are attached inside, and the oil smoke sucked by the intake fan is sucked through the opening. It is configured to be exhausted to the outside through an exhaust duct connected to the hood. Reference numeral 13 in the drawing denotes switches for controlling the operating mode of the fan and the lighting equipment provided on the front panel 14 of the range hood body 10 and for turning the lighting equipment on and off.

The range hood main body 1 thus constructed
0 means that the frontage dimension d is 600 m in this embodiment.
When m, the frontage dimension of the smoke collector 11 is 900 mm
In other words, the frontage dimension of the smoke collector 11 is formed larger than the frontward dimension of the range hood body 10 (d <D). Therefore, the range hood body 10 is arranged substantially in the center of the smoke collector 11. Sometimes, both side plates 16 and 16 of the range hood main body 10 and both side plates 11b and 1 of the smoke collector 11 described above.
The smoke collecting passages 17, 17 having approximately 150 mm in cross section are formed between the smoke collecting passages 1 and 1b.
17 is both side plates 16 and 16 of the range hood body 10.
It is configured so as to communicate with the auxiliary openings 18, 18 opened in.

The auxiliary openings 18 and 18 are provided for the smoke collecting passages 1.
It is opened so that the oil smoke collected at 7, 17 is sucked by the suction force of the intake fan and exhausted to the exhaust duct. At the factory shipping stage, the so-called “smoke” can be easily punched out. It may be "half-cut" or may be configured to be opened in advance and closed with a removable lid.

Of course, depending on the arrangement state of the range hood device 1, the smoke collecting passage 17 is formed so as to be offset to either one of the range hood main body 10, or the left and right smoke collecting passages 17, 17 are formed. They may be formed with different frontage dimensions.
In this case, the auxiliary opening 18 can be opened in either one of the both side plates 16 of the range hood 10, or can be opened by appropriately changing the size of the opening.

Further, if the smoke collecting passages 17, 17 are left open in front, the appearance will be unsatisfactory and the collected oil smoke will easily leak. Therefore, in this embodiment, the range hood main body is used. The front gap is closed by a front panel 19 made of the same material as the front panel 14 of FIG.

FIG. 4 shows a range hood device 1 according to a second embodiment of the present invention. In this embodiment, one side plate 11b 'of both side plates 11b, 11b of the smoke collector 11 is shown.
Is extended downward and is fitted to the side portions of the side plates 11b, 11b slidably in the smoke collecting passages 17, 17 via guide rails (not shown) or the like. The U-shaped slide bodies 20 and 20 are attached, and the slide bodies 20 and 20 are pulled out to the front side, and the smoke collecting channels 17 and 1
7 is configured to be extended forward. Of course, the slide body 20 may be attached to either one of the range hood main bodies 10, and the front side of the slide bodies 20 and 20 is closed by the front panel 19. The same components as those of the first embodiment in the configuration of the present embodiment are designated by the same reference numerals as those used in the first embodiment, and detailed description thereof will be omitted here.

Therefore, the range hood device 1 according to this embodiment can surely raise the oil smoke generated from the heating device to the one smoke collecting passage 17 along the extended side plate 16a. At the same time, since it can be pulled out to the front side together with the slide bodies 20, 20, the efficiency of collecting oil and smoke by the range hood device 1 can be improved if necessary.

In the second embodiment, one side plate 11b 'of both side plates 11b, 11b of the smoke collector 11 is extended downward, but the present invention is not limited to this. For example, as shown in FIG. 5, the side plates 11b, 11b of the smoke collector 11 may normally be polymerized on the outside of one side plate 11b of the smoke collector 11, and may be pulled down as necessary. Slidable extension plate 11d
May be arranged.
