Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a flap type range hood that is installed above a gas range or an electric range.

(Prior art) Range hoods or ventilation fans with built-in exhaust devices are used to exhaust combustion gases, odors, etc. generated in the kitchen, but these are not suitable for gas ranges or electric ranges due to their purpose. In the case of the latter type of ventilation fan, a hood is usually attached to cover the ventilation fan in order to increase collection efficiency.

By the way, range hoods and ventilation fan hoods are constructed in such a way that the front plate of the hood protrudes forward in order to increase the area of the bottom opening in order to increase the collection effect. This has the problem of protruding forward from the front door of the adjacent hanging cabinet, which impairs the harmony with the hanging cabinet.

Therefore, when not cooking, the front plate of the range hood and ventilation fan hood should be approximately flush with the door surface of the hanging cabinet, and when cooking and operating the range hood and ventilation fan, the front plate of the range hood and ventilation fan hood should be stretched forward. Flap-type range hoods or flap-type ventilation fan hoods have been developed that can be extended to widen the area of the bottom opening.

Therefore, in the opening/closing mechanism of the front plate with a flap in conventional flap-type range hoods and flap-type ventilation fan hoods, the upper edge of the front plate is hinged to the front edge of the top plate of the hood body so that it can be rotated in the front-back direction. The substantially fan-shaped flaps, which are pivotably supported and fixedly protruding rearward on both sides of the back side of the front plate, are placed inside the left and right side frames of the hood body, and furthermore, there are telescopic arm rods between the front plate or the flaps and the side frames. An opening/closing movement control mechanism such as a sliding arm lever or the like is provided to regulate the drawing/opening position of the front plate.

Therefore, flaps and opening/closing movement control mechanisms are installed on the left and right sides of the hood body, making the interior complicated and difficult to clean.Furthermore, when the front panel is opened, the flaps and opening/closing movement control mechanisms are installed on the left and right sides of the hood body. The problem is that the opening/closing movement control mechanism appears on the outside of the protruding flap, which is visible to the public and spoils the appearance.

(Problems to be Solved by the Invention) In view of the above-mentioned conventional circumstances, the present invention has a structure in which there is no mechanism for controlling flaps and opening/closing movements within the hood body.

[Structure of the idea]

(Means for Solving the Problems) The technical means taken by the present invention to solve the above problems is to form the left and right side frames of the hood body into hollow shapes, and to form slits in the front surfaces of the hollow side frames. A flap that has been opened and fixed to the front plate is inserted into the hollow side frame, and a roller that bounces upward and downward is installed in the hollow side frame, and the roller fits into the recess that engages with the front and rear of the lower edge of the flap that slides on the upper surface of the roller. Form a notch.
Note that the above-mentioned hood main body is not limited to one in which an exhaust device is integrally assembled inside, but can also be applied to a single hood that covers a ventilation fan.

(Function) According to the above means, the flap fixed to the front plate can be stored in the side frame or pulled out through the slit formed in the front face of the hollow side frame, and the flap can be moved to the opening and closing positions of the front plate. Control is performed by the lower edge of the flap sliding on the upper surface of the roller, and the roller elastically fitting into the recesses cut out at the front and rear.

(Embodiment) Hereinafter, embodiments of the present invention will be explained based on the drawings. Figs. 1 and 2 show a flap type range hood with an exhaust system integrated inside, and in the figure, 1 indicates the hood body. , 2 is a front plate, 3 and 3' are flaps, 4 is an exhaust device, and 5 is a roller.

The hood body 1 has left and right side frames 1 formed of flat metal plates.

A unitized exhaust device 4 is housed inside the hood body 1.

The left and right side frames 1a of the hood main body 1 are formed into a hollow flat shape, and a slit 6 is provided in the front surface of the hood body 1 through which flaps 3 and 3' fixed to both sides of the rear surface of the front plate 2 can be inserted and removed. An edge frame 7 having a substantially L-shaped cross section is integrally fixed to the outer peripheral edge of the side frame 1a, and a noncombustible material 8 can be attached to the outer surface of the side frame 1a.

A front plate 2 supported on the front surface of the hood body 1 so as to be openable and closable is formed in a rectangular shape capable of closing the front opening of the hood body 1, and has approximately fan-shaped flaps 3 on both sides of the rear surface of the front plate 2. 3' is fixed at right angles toward the rear, and the upper edge of the front plate 2 crosses the front edge of the top plate 1c of the hood main body 1 to form a hinge 9.
The left and right flaps 3, 3'
is fitted into the side frame 1a through a slit 6 and is in sliding contact with the upper surface of a roller 5 which is movable vertically and is fixed within the side frame 1a.

Further, approximately semicircular recesses 10, 10 are provided at predetermined intervals at the front and rear of the arcuate lower edges of the flaps 3, 3'.
10' is formed. The formation positions of the recesses 10, 10' determine the closing and opening positions of the front plate 2, and the opening angle of the front plate 2 is determined by the distance between the front and rear recesses 10, 10'. .

The roller 5 that slides and guides the flaps 3 and 3' is rotatably supported by a screw 13 at the approximate center of a swinging rod 12 on a base plate 11, and the roller 5 is mounted on the upper end of the swinging rod 12.
is rotatably pivoted, and a spring 14 is tensioned between the lower end of the swinging rod 12 and the end of the substrate 11, and the tension of the spring 14 constantly presses the roller 5 upward. has been done. The roller 5 constructed as described above is fixed at a predetermined position by fixing its substrate 11 to one of the side plates forming the hollow side frame 1a with screws 15.

Also, rollers 5 for slidingly guiding the flaps 3, 3'
has flanges on both the left and right sides to prevent the flaps 3, 3' from shifting left and right and coming off.

The exhaust device 4 housed in the hood main body 1 is made into a unit by a casing 4a, a fan 4b, and a motor 4c, and is installed and fixed across a mounting device 16 fixed to the back plate 1b.
The exhaust section is connected to an exhaust port provided on the top plate 1c, and is also connected to an L-shaped duct 17 on the top plate 1c. In addition, a filter 1 is installed in front of the exhaust device 4.
