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, which has a front panel that can be opened and closed, was 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 above-mentioned conventional circumstances, the present invention aims to prevent outside air and outdoor noise from flowing into the room through a filter provided on the hood body.

(Means for Solving the Problems) The technical means of the present invention for solving the above problems is to attach a shielding plate to 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 rear directions, By closing the front plate, the shielding plate blocks the filter surface or the communication path to the filter.

The shielding plate has a structure in which it is bonded to and covers the entire surface of the filter, and a structure in which it blocks a communication path to the filter that is partitioned by the front plate of the hood body.

(Function) With the above means, when the front plate is closed, the shielding plate covers the entire surface of the filter or blocks the communication path, and the outside air and outdoor noise that have flowed into the exhaust system from the duct flow into the room. to prevent

Furthermore, when the front plate is pulled out toward the front, the shield plate separates from the filter surface and opens the communication path so that the inside and outside of the filter are in communication with each other, allowing smoke, oil, steam, etc. to be absorbed.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 3 show a form of blocking the communication path to the filter, in which 1 is the hood body, 2 is an exhaust device, 3 is a filter, 4 is a front plate, 5 is an exhaust duct connected to the exhaust device, 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,
A stay 9 for regulating the opening angle of the front plate 4 is attached to the lower part of the front plate 4, and a stay 9 is attached to the side plate 1a of the hood body 1.
The front plate 4 is inserted into and supported by a receiving fitting 10 attached to the hood body 1, and a magnet 11 is fixed to the lower front end of the side plate 1a of the hood main body 1, and the front plate 4 is moved closed.
It is designed to absorb and hold.

A shielding plate 6 is fixedly and protrudingly provided on the back side of the front plate 4a of the front plate 4 in an upwardly inclined manner, and when the front plate 4 closes, the tip of the shielding plate 6 joins to the mounting frame 7' and is attached to the filter 3. In addition to blocking the communicating path a, the rear end surface of the side plate 4b joins to the mounting frame on the outer periphery of the filter to thereby block the communication path a.

Incidentally, the shielding plate 6 acts as a guide plate to effectively flow smoke, oil, etc. generated from the range toward the filter 3 when the front plate 4 is rotated.

FIGS. 4 and 5 show a form in which the entire surface of the filter is covered and closed, and the same members as those in the previous embodiment are designated by the same reference numerals and explanations thereof will be omitted. A shielding plate 12, which is slightly larger than the filter 3, is fixed via a mounting rod 13 to the back side of the front plate 4, which is attached to the hood body 1 so as to be openable and closable.
2 is joined to the front surface of the filter 3 by the closing movement of the front plate 4 to cover and close it.

The exhaust device 5 in each of the embodiments described above is shown for a range hood that is housed in a space defined by mounting frames 7, 7' provided inside the hood body 1 and a filter 3 mounted across them. However, the same effect can be achieved with a range hood that is 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.

(Effect of the invention) The range hood of the invention has a shielding plate attached to the front plate that moves to open and close, and the shielding plate covers the entire surface of the filter or blocks the communication path to the filter when the front plate closes. Therefore, when the front plate is closed and the exhaust system is not in use, the filter or communication path is closed, and it is possible to reliably prevent outside air and outdoor noise that have flowed into the exhaust system from the exhaust duct from flowing into the room. Moreover, the shielding plate that prevents the outflow is used to block the filter that is the communication port into the room or the communication path to the filter in the hood body, so if a shutter is installed in the exhaust duct, the shutter and the duct are connected. Even if outside air or outdoor noise were to infiltrate through the gaps in the room, it would be possible to reliably prevent it from flowing into the room. Furthermore, since the prevention of its outflow is automatically performed by closing the front plate, there is no need for any separate operation, which is very convenient.
