Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to improvement of a range hood provided with a filter which is installed and used above a gas stove or the like.

(Prior Art) A range hood installed above a gas stove, an electric range, or the like has a blower unit housed in a hood body whose bottom surface is open, and a filter is attached to the upstream front side of the blower unit. The oil smoke and odor generated by cooking are sucked and exhausted.

(Problems to be solved by the invention) In the conventional range hood described above, oil and fat generated by cooking pass through a filter to capture oil and fat, thereby preventing the blower unit and the duct from being contaminated. .

By the way, since this kind of range hood is installed right above the gas stove as described above, if you put a tempura pan on the gas stove and fry the tempura, it is likely that the tempura oil will catch fire. If there is, the ignited flame rises directly above and hits the filter directly. In this case, since oil and fat are captured and accumulated on the filter, there is a danger that a flame that is directly radiated ignites this and spreads the fire.

The present invention has been made in view of the problems of the prior art as described above, and the purpose thereof is to prevent the occurrence of flames such as the fire of the stove igniting the tempura oil during cooking. It is to provide a range hood that blocks the flame from directly hitting the filter and prevents a fire from spreading.

(Means for Solving the Problems) In order to achieve the above object, in the range hood of the present invention, a blower unit is housed in a hood body whose bottom surface is open, and the hood body is provided upstream of the blower unit. In the range hood where the filter is attached so as to face the front plate, a flameproof plate of a size that covers the horizontal projection surface of the filter can be attached to and removed from the upstream side of the filter upward from the lower mounting frame of the filter. In addition, it is characterized in that an inflow port is secured between the upper end of the flameproof plate and the top plate of the hood body.

The flameproof plate is formed of a metal plate having high heat resistance and fire resistance, and the flameproof plate is fixed by a screw or the like to the lower plate partitioning the accommodating portion of the blower unit or the lower mounting frame into which the filter is inserted. It is detachably attached.

(Operation) According to the above means, since the flameproof plate covers the horizontal projection surface of the filter upward from the lower mounting frame of the filter, the flameproof plate blocks the flame from directly hitting the filter, Prevents the oil and fat trapped and accumulated on the filter from catching fire.

(Effect of the device) Since the range hood of the present invention is configured as described above, even if a flame rises during cooking, the flame is blocked by the flameproof plate that covers the horizontal projection surface of the filter. Is prevented from being directly exposed.

Therefore, it is possible to prevent the oil and fat that is captured and accumulated on the filter from catching fire, and to prevent the fire from spreading.
It is possible to provide a safe range hood.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a hood main body having an open lower surface, which is composed of a box body 1a formed by a flat plate made of metal in a form in which a front surface and a lower surface are open, and a front plate 1b attached so as to cover the front surface of the box body 1a, Inside the hood body 1, the lower plate 2 and the filter 3 form a compartment 5 for the blower unit 4, and the blower unit 4 is accommodated and installed in the compartment 5.

Further, the front plate 1b attached to the front surface of the box body 1a is detachably attached with its upper end edge engaged with the front end edge of the top plate of the box body 1a.

The lower plate 2 that divides the accommodating portion 5 is fixed to the back plate and the left and right side plates of the box body 1a and is installed substantially horizontally corresponding to the lower surface of the box body 1a. The front end of the lower plate and the top of the box body 1a. The filter 3 is detachably mounted in the filter mounting frame 6 fixed to the plate.

The filter 3 is an aluminum plate in which slits are engraved and cut and raised to form a ventilation hole, and is formed by a single piece or a combination of a plurality of pieces.

The blower unit 4 installed in the accommodating part 5 is composed of a casing 4a, a motor 4b, and a fan 4c.
A bell mouth is attached to the front surface of 4a to form an intake port, and the exhaust side formed in the casing is connected to a through hole formed in the top plate of the hood body 1, and the through hole of the top plate is The exhaust duct 7 is connected via the duct connection cylinder.

Reference numeral 8 is a flameproof plate, which is made of a metal flat plate having high heat resistance and fire resistance and is formed in such a size as to cover the horizontal projection surface of the filter 3, and one side thereof is fixed to the lower plate 2 with a set screw 12. At the same time, the other side portion is attached to the engaging portion 10 formed on the flameproof plate receiver 9 fixed to the inner side surfaces of the left and right side plates of the hood body 1 so as to be inclined upward. An inflow port 11 is formed between the upper end of the flameproof plate 8 and the top plate of the hood body 1. Further, the attachment of the flameproof plate 8 is not limited to the form of being screwed to the lower plate 2, but may be screwed to the filter mounting frame 6 as shown in FIG.

With the above configuration, when the flame rises due to ignition of the tempura oil or the like, the flame is blocked by the flameproof plate 8 and the flame is prevented from directly hitting the filter 3.

Further, since the flameproof plate 8 rises upward from the lower side edge of the filter 3 with a space from the filter surface, oil smoke and odor generated by cooking are directed to the inlet 11 side along the flameproof plate 8. Since it is guided, the collection effect is also improved.
