Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a duct cover for concealing an exhaust duct provided above a range such as a kitchen.

[Prior Art] In a system kitchen or the like, a range hood is usually attached above the range, and a fan for intake is incorporated in the range hood, and smoke or steam is exhausted to the outside through a duct following the fan. It is supposed to do.
In this case, if you can see the duct, it will look bad,
When there is a hanging cabinet beside the range hood, a decorative plate is attached to the range hood so that the duct cannot be seen from the front side. If there is no hanging cabinet on the side, the duct becomes invisible by attaching the horizontal curtain plate, but it is difficult to design.

Therefore, when there is no hanging cabinet, a tubular duct cover b is attached to the upper part of the range hood a as shown in FIG. 4, and the duct is concealed by the duct cover.

[Problems to be solved by the invention] However, when the duct cover is used, there is no particular problem when the exhaust port is provided on the wall c side, but the duct cover cannot be connected to the wall side due to the layout and the like, and the ceiling is not provided. In the case of connecting to an exhaust duct arranged on the back side, there is a problem that it cannot be applied as it is because it is bent in a hook shape. Therefore, as a duct cover for connecting to the ceiling side, it is necessary to prepare a straight pipe type that extends straight upward, but depending on the building, the height of the ceiling differs, so it is difficult to install with a fixed length. It happens.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a ceiling-connecting duct cover that can be immediately applied regardless of the height of the ceiling.

[Means for Solving the Problems] As a means for solving this technical problem, the present invention provides a range hood provided above a kitchen stove and an exhaust duct provided behind the ceiling. In a tubular duct cover for concealing a straight pipe type duct to be connected, an upper cover whose upper end is fixed to the ceiling, and a lower end having a diameter smaller than the front width of the range hood and an upper part of the range hood. A duct cover is configured with a lower cover fixed to the upper cover, and the lower cover is fitted so as to be covered by the upper cover, and the length of the overlapping portion that fits with each other is changed, so that the entire length of the duct cover is increased. The gist is that it can be adjusted according to the height of the.

[Operation] By changing the length of the overlapping portion where the upper cover and the lower cover are fitted to each other, that is, by expanding and contracting, the total length of the duct cover can be easily adjusted according to the height of the ceiling.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 is a range hood, which is fixed above a range 2 of a kitchen and fixed to a wall 3. A sirocco fan 4 is incorporated inside, and a duct 5 is attached following the sirocco fan. Has been. Reference numeral 6 denotes a lower cover for forming a duct cover, which is attached to the upper portion of the range hood 1 and hides the duct 5. Reference numeral 7 denotes an upper cover for constituting a duct cover, which is attached to an exhaust port 8a provided in a ceiling 8 and the lower cover 6 is fitted into the upper cover to form a duct cover 9 from below. . An exhaust duct 10 is provided behind the ceiling 8 and is connected to the duct 5 of the range hood 1.

The present invention is configured as described above, and the smoke or the like generated in the range 2 during cooking is sucked by the sirocco fan 4 of the range hood 1 and is exhausted by the duct 5 to the exhaust duct 10 in the ceiling. In this case, since the length of the duct cover 9 can be adjusted arbitrarily, the duct cover 9 can be easily attached even if the height of the ceiling differs depending on the building.

That is, when the ceiling 18 is high as shown in FIG. 2, a long duct cover 19 can be formed by reducing the insertion amount of the lower cover 16 with respect to the upper cover 17.
On the other hand, as shown in FIG. 3, when the ceiling 28 is low, the short duct cover 29 can be formed by increasing the insertion amount of the lower cover 26 with respect to the upper cover 27. Therefore, the duct cover can be mounted immediately without any processing such as cutting or joining, and therefore the mounting work on site becomes extremely simple.

[Advantages of the Invention] As described above, according to the present invention, the duct cover of the range hood can be formed by the upper cover and the lower cover, and the lower cover can be fitted so as to be covered with the upper cover. Therefore, the length of the duct cover can be easily adjusted according to the height of the ceiling, which makes the installation work on site extremely easy and efficient. In addition, smoke that has flowed into the duct cover can be prevented from leaking to the room side through the gap between the upper cover and the lower cover, and dust and oil deposits that float on the room side can leave the gap between the upper cover and the lower cover. Can be prevented from entering the inside of the range hood, and the duct cover has a structure that hides only the duct, making it compact and compact, especially when applied to a duct cover that exhausts to the ceiling side, its effect is remarkable. Is.
