Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a range hood installed above a gas range, an electric range, an electromagnetic plate, etc., which are kitchen equipment such as a system kitchen.

[Prior Art and Problems Thereof] Conventionally, as shown in FIG. 4, for example, a range hood has a built-in filter and communicates with a ceiling surface of a divergent main body (a ₁ ) having inclined front and both side surfaces. connect the cylindrical cover (a _2), the propeller fan (20 this cylindrical cover (a ₂₎
0) is housed. By the way, due to the smoke exhausting action of the range hood, the kitchen becomes a negative pressure. As a result, it is necessary to supply outside air into the kitchen by some means. ing.

However, if an air supply register etc. is installed separately for the range hood, not only the cost rise will be inevitable,
Installation work is separately required, which is troublesome and requires a high construction cost, which is not preferable.

[Technical problem] A technical problem of the present invention is to newly provide a range hood having a smoke exhaust function and an outside air supply function.

[Technical means] The technical measures taken to achieve the above technical issues are as follows:
A filter and a blower are sequentially installed from the bottom opening in a range hood body provided with a cylindrical cover in communication with the ceiling of the body having an opening at the ceiling and the bottom, and the blower is provided so as to divide the body into two parts. A plate is provided so as to be isolated from the filter side, and a shield plate is provided with a smoke introduction port in a portion facing the intake port of the blower in close proximity to the intake port, and the blower is connected to an exhaust duct. And an air supply hole is provided in the cylindrical cover.

[Operation] The operation of the technical means of the present invention is as follows.

Since the blower is separated by a shield provided so as to divide the main body into two parts, the smoke passes through the filter and is sucked directly into the inside of the blower from the smoke inlet of the shield adjacent to the suction port of the blower. And is discharged outside the room by the exhaust duct.

On the other hand, smoke does not enter the cylindrical cover, and outside air flows in through the air supply duct due to the negative pressure phenomenon in the kitchen, and is naturally supplied into the kitchen from the air supply hole.

If even a small amount of fats and oils is not removed by the filter, the fats and oils do not adhere to the outer surface of the blower or a narrow space around the blower, but adhere to the surface of the shielding plate.

[Effects of the Invention] The present invention is configured as described above and has the following advantages.

The installation and installation can provide a smoke exhaust function and an outside air supply function, and do not require a separate means (ventilation register) for supplying outside air.

The oils and fats that are not removed by the filter adhere to the shield provided in front of the blower so as to traverse the inside of the range hood main body. Oil and grease do not adhere to the narrow space between the blower and the range hood body around the outer surface as well as around the filter and behind the filter, so that the cleaning operation is easy and injuries due to burrs and the like in the narrow space during cleaning. There is no danger and it is safe.
