Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a range hood, and more particularly to an improvement of a boot-type range hood in which a front plate is fixed to the front of the hood body.

(Conventional technology and its problems) This type of range hood is located above the gas range (cooking table) and is installed adjacent to the hanging cabinet. is becoming desirable. This is especially noticeable in the case of system kitchens, which have recently become popular, and many use boot-type kitchens with a wider opening on the bottom to more effectively collect smoke, oil, steam, etc. generated during cooking. There is.

By the way, in this type of range hood, the exhaust system installed inside the hood body communicates with the room through a filter attached to the hood body, so outside air and outdoor noise that enters through the duct connected to the exhaust system are removed. There is a problem with the exhaust system entering the room via the filter. Particularly in the winter, cold outside air flowing into a room has a large effect on indoor heating and the like. Note that some exhaust ducts are equipped with a shutter to prevent outside air from entering, but even in this case, a gap is provided between the inner surface of the duct and the shutter to ensure smooth operation of the shutter. Because outside air and external noise flow into the room, it is impossible to completely prevent the inflow.

(Purpose of the invention) In view of the above-mentioned conventional circumstances, the present invention provides a range hood equipped with a closing means that prevents outside air and outdoor noise from flowing into the room through an exhaust device and a filter provided in the hood body. It's about doing.

(Structure of the invention) The technical means taken by the invention to achieve the above object is a range hood that is equipped with an exhaust device inside the hood body and has a front plate fixed to the front of the hood body. A closing plate body that closes the opening between the front plate and the front of the exhaust device is rotatably and lockably attached via a hinge to the lower back side of the It can be brought into close contact with the cushion material on the bracket fixed across the side wall of the plate and the side wall of the hood main body, and furthermore, a blinding plate is fixed and extended on the back side of the attachment part of the closing plate main body to the hinge.

The closing plate body is sized to close the opening between the switch storage area on the back side of the front plate and the lower end of the filter on the front of the exhaust system, and side plates are attached at right angles to both left and right sides of the closing plate body to connect it to the hood body. It closely fits with the cushion material on the bracket attached to the front plate to fill the height of the flange to establish a sealed state. In addition, several hinges are installed at intervals in the width direction to support the closing plate body so that it can be opened and closed.
Close the gaps between the hinges with blind boards. Furthermore, springs, magnets, etc. can be arbitrarily selected and used to maintain the open and closed states of the closing plate body.

(Function) According to the above configuration, when the range hood is not in use,
When the closing plate body is closed, the opening between the front plate and the filter is closed by the closing plate body, and the gap between the front plate side wall and the hood body side wall and the side edge of the closing plate body is closed by the front plate and the hood. A bracket with cushioning material fixed to the side wall of the main body and side plates connected to the left and right edges of the closing plate body are used to seal the door, and the gap between the hinges is closed by a blind plate fixed to the back side of the closing plate body, creating a complete seal. A closed mouth condition is established. Further, when the closing plate main body is opened, the closing plate main body projects forward from the lower end of the front plate, thereby expanding the collection range of oil smoke and the like generated from the cooking table.

(Embodiment) An embodiment of the present invention will be described below based on the drawings. In the figure, 1 is the hood body, 2 is the exhaust system, and 3
4 is a filter, 4 is a front plate, 5 is an exhaust duct connected to an exhaust device, and 6 is a closing plate attached to the front plate 4.

The hood main body 1 is formed into a rectangular box shape with open front and bottom surfaces, and includes left and right side plates 1a, a back plate 1b, and a top plate 1c formed of flat metal plates, and inside the hood main body 1 are a casing 2a, a fan 2b, and a motor 2c. An exhaust system 2 consisting of
A filter 3 is mounted in front of the exhaust device 2 in an inclined manner via mounting frames 7, 7'.

The front plate 4, which is removably connected to the front surface of the hood body 1, is composed of a rectangular front plate 4a, and triangular side plates 4b connected to the left and right sides of the front plate 4a. The flanges 8 formed on the rear edges of the left and right side plates 4b are attached to the left and right side plates 1a of the hood body 1.
It is fixed by being joined to a flange 9 formed on the front edge of. Further, a cover 10 is attached to the lower part of the back side of the front plate 4a of the front plate 4, and the switch storage part 1 is
A closing plate 6 is attached to a cover 10 of the switch housing 11 via a hinge 12.

The closing plate 6 includes a rectangular closing plate main body 6a having the same size as the opening defined by the lower end of the filter 3 and the rear surface of the switch housing 11 of the front plate 4a, and a rectangular closing plate main body 6a on both left and right sides of the closing plate main body 6a. Installed side plate 6b
and a blinding plate 6c which is fixed and extended on the upper part of the closing plate main body 6a.

The closing plate main body 6a is formed into a rectangular shape using a heat-resistant metal flat plate, and has a hinge 12 on one side fixed to the cover 10 of the switch storage section 11.
A magnet 13 is provided on the other side of the closing plate main body 6a and is attached to the mounting frame 7' of the filter 3 by attraction.

The magnet 13 is a hollow cylindrical frame 1 made of synthetic resin.
4, and is configured to elastically engage and disengage from the mounting frame 7'. Further, two to three hinges 12 that rotatably support the closing plate main body 6a are provided at intervals in the width direction.

The side plates 6a fixed perpendicularly to the left and right sides of the closure plate main body 6a have a predetermined width and are fixed to the closure plate main body 6a by spot welding, and the side plates 6b are attached to the side walls of the hood main body 1 and the front plate 4 by flanges. Bracket 1 attached so that it is the same height as 8 and 9

The blinding plate 6c closes the gap created between the hinges 12 connecting the cover 10 and the closing plate main body 6a, and is fixed to the upper part of the closing plate main body 6a and extends upwardly. When the closing plate 6 is bent into a dogleg shape, the upper side of the blinding plate 6c is brought into close contact with the rear surface of the cover 10. A cushion material 17 is attached to the rear surface of the cover 10 to which the upper side of the blind plate 6c is joined, so that the blind plate 6c is elastically engaged with the cushion material 17.

Further, the above-mentioned means for maintaining the open state of the closing plate 6 is provided by tensioning a tension spring 18 between the closing plate main body 6a and the front plate 4, so that the attachment part on the closing plate main body 6a side extends forward beyond the butterfly axis. By positioning the opening, an upward pulling force acts to maintain the open state.
In addition, a handle is attached to the front surface of the closing plate body so that the closing plate can be easily opened and closed.

(Effects of the Invention) Since the range hood of the present invention is constructed as described in detail above, by closing the closing plate, the opening defined by the front surface of the filter and the front plate can be completely closed. Therefore, when the range hood is not in use, outside air and outdoor noise flowing into the exhaust device from the exhaust duct can be prevented from flowing into the room.

In addition, since the closing plate rotates around its top, when the range hood is used and opened, the tip of the closing plate protrudes forward from the front plate, making it difficult to capture smoke, steam, etc. generated from the cooking surface of the range. It is possible to expand the collection range and enhance the collection effect.
