Abstract

PURPOSE:To improve the efficiency of trapping soots by providing a blower so that its suction port is positioned substantially within a vertical side frame body and frontwardly inclining the front surface of the vertical side frame member frontwardly toward the horizontal side frame member. CONSTITUTION:When a blower 4 is operated during cooking, smoke soots generated by a gas range 17 and rising up are sucked up through a main body suction port 8. Upon this occasion, soots diffused rearward rise up along the front panel 3a of a vertical side frame body 3 and are sucked up into the main body suction port 8 and soots diffused frontward are drawn near to the main body suction port by a Coanda effect 8 and trapped. The thus trapped soots are discharged to the outdoors from a main body discharge port 7 through a duct 11. Since the suction port 5 of the blower 4 is located within the vertical side frame main body 3, the suction air flow speed of the main body suction port 8 becomes quick on the rear side and hence the flow of soots in the vicinity of the main body suction port 8 is inclined from the front part toward the rear part, and thus soots are positively trapped without leaking forwardly of the main body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a range hood for exhausting oily smoke from a kitchen.

BACKGROUND OF THE INVENTION Conventionally, there has been a demand for a range hood of this type that is configured to reliably collect oily smoke generated during cooking so as not to stain surrounding walls, etc.

For this reason, conventional range hoods have been constructed as shown in FIG. 3, for example. That is, the frame 3
A Coanda action plate 33 is mounted on the lower surface of the gas range 32 so as to be tilted forward as it goes from the rear of the gas range 32 toward the lower surface of the frame 31. A vent 34 is provided, and a blower 3 for exhaust is installed directly below the exhaust port 36 opened on the upper surface of the frame 31.
6 was provided. Further, from the exhaust port 36 to the back wall 37
An exhaust duct 39 communicates with a ventilation opening 38 provided in the interior of the room, and a weather cover 40 is provided on the outdoor side of the ventilation opening 38 to prevent rainwater from entering the room.

In the above configuration, when the blower 36 is operated during cooking,
Among the generated oil smoke, the oil smoke behind the gas range 32 rises along the Coanda action plate 33 as shown by arrow P, so the oil smoke in front of the gas range 32 also rises along the Coanda action plate 33 as shown by arrow Q. I am drawn to 33. Therefore, most of the generated oil smoke is usually sucked into the intake port 34, passes through the exhaust port 36, and is discharged outdoors from the ventilation port 38.

(For example, Japanese Unexamined Patent Publication No. 60-186637) Problems to be Solved by the Invention By the way, in such a conventional configuration, the blower 36 is
Since it is provided above the intake port 34, the suction air velocity at the intake port 34 is substantially uniform over the entire surface. However, if a large amount of oil smoke is generated from the gas range 32 and flows in front of the gas range 32, the Coanda action of the Coanda action plate 33 alone will not be enough to pull it backwards, and the smoke will leak to the front of the frame 31. There was a problem with this.

There is also a problem in that the frame 31 occupies space from above the gas range 32 to near the ceiling.

The present invention solves these problems, and aims to provide a space-saving range hood that can reliably collect even if a large amount of oil smoke is generated.

Means for Solving the Problems In order to solve this problem, the present invention provides a main body that is hollow inside and formed in an almost inverted shape by a horizontal side frame body and a vertical side frame body; Main body intake port provided on the underside of the body,
and a blower provided in the main body so that the suction port is located approximately within the vertical side frame, and the front surface of the vertical side frame is tilted forward toward the horizontal side frame. It is composed of

Effect With this configuration, the air inlet of the blower is located inside the vertical side frame, so the suction wind speed of the main body intake becomes faster at the rear, and the oil smoke that rises near the main body intake is directed to the rear. , it will be reliably collected without leaking to the front of the main body. Further, since the blower is installed in or near the vertical side frame within the main body, the horizontal side frame does not occupy a large space above the gas range or the like.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. That is, the vertical side frame 3 has a vertical side frame 3 whose front plate 3a is tilted forward as it goes toward the horizontal side frame 1 at a distance of 5' from the horizontal side frame 2. A blower 4 is installed inside the main body 1 so that the suction port 5 is located inside the vertical side frame 3 and the bent outlet 6 is aligned with the main body exhaust lower provided at the rear of the upper surface of the horizontal side frame 2. It is set up in An adapter 10 is provided on the upper part of the main body exhaust lower to connect a duct 11 that communicates the main body exhaust lower with a ventilation opening 16 provided on the back wall 14. A weather cover 15 is provided to prevent entry into the room. A main body intake port 8 is provided on the lower surface of the horizontal frame 2, and a filter 9 is disposed in the main body intake port 8 to collect oil dust in oil smoke and reduce dirt inside the main body 1. There is. In addition, in the figure, 12i is a lighting device that is installed at the front end of the vertical side frame 2 and does not brightly illuminate the area at hand during cooking.

In the above configuration, when the blower 4 is operated during cooking, the oily smoke generated from the gas range 17 and rising will be sucked in through the main body intake port 8. The oil smoke that rises along the front plate 3a of No. 3 and is sucked into the main body intake port 8, and due to the Coanda effect, the oil smoke that spreads forward is also drawn toward the main body intake port 8 and collected. The collected oil smoke is then discharged outdoors from the exhaust lower of the main body through the duct 11. Incidentally, although this effect is insufficient when a large amount of oil smoke is generated, the suction port 6 of the blower 4 is located inside the vertical side frame 3. In other words, since it is located at the rear inside the main body 1, the suction wind speed of the main body intake port 8 is faster on the rear side, so the flow of oil smoke near the main body intake port 8 is inclined from the front to the rear, and the main body 1. It will be collected reliably without leaking to the front.

In addition, since only a part of the blower 4 is present inside the horizontal side frame 2, the height can be made low, and space is secured above the main body 1, so that the space in the kitchen can be used effectively. Become.

As described above, according to this embodiment, the collection efficiency is particularly high when a large amount of oil smoke is generated, and the surrounding walls 7, etc. are not contaminated, and the shape is reduced.
Effective use of space becomes possible.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the air blower is provided so that the suction port is located almost inside the vertical side frame, so the suction wind speed of the main body suction port is lower on the rear side. Since the flow of oil smoke is directed backwards, the collection efficiency is improved without leaking to the front of the main body, and since the blower is housed in or near the vertical side frame, the height of the vertical side frame can be reduced. The effect is that the space above the main body can be used effectively.
