Description

[Detailed explanation of the invention] (Industrial application field) This invention relates to range hoods. Specifically, when in use, the front plate is pulled out and opened to widen the opening at the bottom, and when not in use, the front plate is closed. This invention relates to a flap hood type range hood whose surface aligns with an adjacent wall cabinet, etc.

(Prior Art) Since this type of range hood is installed adjacent to a wall cabinet, it is desired that the range hood not only have excellent exhaust performance but also harmonize with the wall cabinet. This is especially noticeable in the case of system kitchens, which have recently become popular, and boot-type range hoods with a wider bottom opening are used in order to more effectively collect smoke, oil, steam, etc. generated from the cooking surface. The board will protrude forward from the front of the cabinet. Therefore, a so-called flap hood type range hood with a front panel that opens and closes has been developed to satisfy both performance when in use and harmony when not in use. 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.

(Problems to be solved by the invention) In view of the conventional circumstances as described above, the present invention prevents outside air and outdoor noise from flowing into the room through the filter provided in the hood body, and also includes a member covering the filter. The purpose is to prevent the flow of smoke exhaust etc. from being obstructed when the front plate is opened and used.

(Means for solving the problem) The technical means of the present invention for solving the above problem is to install a connecting rod on the rear side of the front plate that is attached to the front of the hood body so that it can be opened and closed in the front and back direction. A shielding plate is attached through the hood, and the upper part of the shielding plate is rotatably supported within the hood body.

(Function) With the above means, when the front plate is closed, the shielding plate is pushed rearward through the connecting rod and covers the entire surface of the filter, preventing outside air and outdoor noise flowing into the exhaust system from the duct. Prevent it from leaking into the room.

Also, when the front plate is pulled out, the shield plate is rotated in the opening direction by the connecting rod around its upper pivot point, the rear surface of the shield plate is separated from the filter, and the inside and outside are communicated through the filter. When the exhaust system is activated, smoke, oil, steam, etc. are sucked and discharged.

The shielding plate is rotated around the upper pivot point and is supported in an inclined manner so that the lower end touches the back surface of the front plate, and is guided to ensure that smoke, oil, steam, etc. are sucked into the exhaust system. Acts as a board.

(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 shielding plate attached to the front plate 4.

The hood main body 1 is formed into a rectangular box shape with the front and lower surfaces open, with left and right side plates 1a, a back plate 1b, and a top plate 1c formed of flat metal plates, and a casing 2a, a fan 2b, and a motor 2c are installed inside the hood main body 1. 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 supported on the front surface of the hood body 1 in an openable and closable manner, includes a rectangular front plate 4a that closes the front opening of the hood body 1, and triangular side plates 4b connected to the left and right sides of the front plate 4a. The front plate 4 is rotatably attached at its upper edge to the front edge of the top plate 1c of the hood main body 1 with a hinge 8, so that it can be opened and closed. Further, between the front plate 4 and the hood body 1, a control means for regulating the opening angle of the front plate 4 and a holding means such as a magnet for supporting the closed front plate 4 in the closed state are provided as appropriate. There is.

A shielding plate 6 is provided between the front plate 4a of the front plate 4 and the filter 3.

The shielding plate 6 is made of a heat-resistant metal flat plate, and has a size that can cover at least the entire surface of the filter 3, and mounting pieces 9, 9 are provided on both upper sides of the outer surface of the shielding plate 6. ' are fixedly protruded and rotatably supported on the hood main body 1 via the mounting pieces 9, 9' on support shafts 10, 10', and the outer surface of the shielding plate 6 and the front plate 4a Connecting rods 11, 11' are connected and pivoted across the front plate 4.
In conjunction with the opening/closing movement of the shielding plate 6, the supporting shafts 10, 10'
It rotates around , and can freely approach and separate from the filter 3.

In the embodiments described above, the range hood is shown in which the exhaust device 2 is housed in a space defined by the mounting frames 7, 7' provided inside the hood body 1 and the filter 3 mounted across them. However, the same effect can be achieved with a range hood equipped with a so-called unitized exhaust system in which the exhaust system is housed in a box-shaped case that is smaller than the hood itself, and a filter is attached to the periphery of the case. It is something. Further, the upper support of the shielding plate 6 is not limited to the form shown in the drawings, and it is of course possible to provide a mounting piece projecting from the mounting frame 7 and to support the shielding plate 6 pivotably thereon.

(Effect of the invention) The range hood of the invention has a shielding plate attached to the front plate that opens and closes via a connecting rod, and the upper part of the shielding plate is pivoted to the hood body so that it can rotate freely. The shielding plate also opens and closes in conjunction with the opening and closing movement of the front plate, making it possible to cover the entire surface of the filter or to leave the entire surface of the filter in an open state. Therefore, when the front plate is closed when the range hood is used, the shielding plate is also closed, covering the entire surface of the filter, and the outside air and outdoor noise that have flowed into the exhaust system from the exhaust duct flow into the room. can be prevented.

Further, the above-mentioned shielding plate is rotated around its upper part, and when the front plate is opened, the lower end of the shielding plate is supported in an inclined manner so as to be joined to the lower back surface of the front plate, so that the shielding plate can be moved from the microwave oven, etc. It acts as a guide plate when the generated smoke, steam, etc. is sucked in by the suction force accompanying the operation of the exhaust system, and can enhance the collection effect.
