Abstract

PURPOSE:To effectively collect a large quantity of generated oil smoke by inclining the front face of a vertical side frame forward toward a horizontal side frame, rotating a rotor toward a body suction port, and forming an induction flow along the front face slope of the vertical side frame up to the port. CONSTITUTION:When a discharge blower 4 and a motor 5 are operated at the time of cooking, a belt 3a is rotated toward a body suction port 8 as indicated by an arrow P. Then, an induction flow 16 can be formed from the lower end of a vertical side frame 3 to the port 8 along the front face slope of the frame 3 by the rotation of the belt 3a. In this case, a large quantity of oil smoke generated from a gas range 17 and raised therefrom is effectively induced to the flow 16, sucked from the port 8 without leakage to its periphery, and discharged from a body discharge port 7 through a discharge duct 11 out of a room.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a range hood that discharges carbon dioxide, oil smoke, odor, etc. generated from a cooking device to the outdoors.

2. Description of the Related Art Conventionally, there has been a demand for a range hood of this type that is designed to reliably collect oily smoke generated during cooking so as not to stain surrounding walls and the like.

For this reason, conventional range hoods have been constructed as shown in FIG. 3, for example. That is, the frame 3
A Coanda effect 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 to the lower surface of the frame 31. An intake port 34 is provided for sucking air in, and an exhaust blower 36 is provided directly below an exhaust port 36 opened on the upper surface of the frame 31.
was provided. Furthermore, an exhaust duct 39 was communicated from the exhaust port 35 to a ventilation port 38 provided in the back wall 37, and a weather cover 40 was provided on the outdoor side of the ventilation port 38 to prevent rainwater from entering the room. .

In the above structure, when the exhaust blower 36 is operated during cooking, the generated oil smoke is attracted to the Coanda action plate 33 and rises along the Coanda action plate 33, and usually most of it is sucked in through the intake port 34. , through an exhaust port 35 and exhausted outdoors from a ventilation port 38 (for example, Japanese Patent Application Laid-Open No. 80-186637).

Problems to be Solved by the Invention In such a conventional structure, when 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 is prevented. However, there was a problem in that it could not be drawn all the way to the rear and leaked to the front and left and right sides of the frame 31.

The present invention is intended to solve these problems, and an object of the present invention is to provide a 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 formed of a horizontal side frame body and a vertical side frame body, the inside of which is hollow and approximately shaped like an inverted L, and the horizontal side frame body. A main body intake port provided on the lower surface of the body, an exhaust blower provided in the main body, and an endless rotary rotatable structure, the front surface of the vertical side frame body being tilted forward as it goes toward the horizontal side frame body. This is a range hood in which a moving body is provided in front of the vertical side frame body.

Function: Due to the rotation of the rotating body on the front side of the vertical side frame b1, an induced flow is formed along the front slope of the vertical side frame body at the main body intake port 1, so that the generated oil smoke is reduced. etc. will be attracted by the induced flow and will not leak into the surrounding area.
The waste will be discharged outdoors.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2. That is, the horizontal side frame 2 has a main body intake port 8 on its lower surface, and the endless frame 2 that is rotatably provided.
/ } 3a is provided on the front surface of the vertical side frame 3 whose front surface is tilted forward as it goes toward the horizontal side frame 2, and the inside of the horizontal side frame 2 and the vertical side frame 3 is hollow and almost Inside the main body 1 formed in an inverted L shape, there is an electric motor 5 for rotating the pipe 3a toward the main body intake port 8, and an exhaust blower 4 with an exhaust blower discharge port 6 on the upper surface of the horizontal side frame 2. It is provided so as to match the main body exhaust port 7 provided. An adapter 10 is provided at the top of the main body exhaust port 7 to connect an exhaust duct 11 that communicates the main body exhaust port 7 with the ventilation port 13 provided on the back wall 14. A weather cover 15 is provided on the outdoor side of the housing 13 to prevent rainwater from entering the room. In addition, a filter 9 is disposed at the main body intake port 8 to collect oil dust in oil smoke and reduce dirt inside the main body 1.

In the above structure, when the exhaust blower 4 and the electric motor 5 are operated during cooking, the bell 3a rotates as shown by arrow P toward the main body intake port 8. Then, the induced flow 16 can be formed from the lower end of the vertical side frame 3 at the main body intake port 81 along the front slope of the vertical side frame 3 by the rotation of the bell 3a. At this time, a large amount of oil smoke that is generated and rising from the gas range 17 is reliably attracted by the induced flow 16, and is sucked in from the main body intake port 8 without leaking to the surroundings, and passes through the main body exhaust port 7 through the exhaust duct 11. The waste will be discharged outdoors.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the front surface of the vertical side frame body is tilted forward as it goes toward the horizontal side frame body, and the rotating body is rotated toward the main body intake port. By moving the main body intake port case, an induced flow is created that flows along the front slope of the vertical side frame body, so the generated oil smoke is reliably attracted to the induced flow and discharged outdoors without leaking to the surroundings. Therefore, even if a large amount of oil smoke is generated, it can be reliably collected.
