Description

  The present invention relates to a filter attachment frame for attaching a filter for a range hood to a required position, for example.

In order to prevent the ventilation fan and exhaust duct attached inside the range hood from being contaminated, a filter for the range hood is attached to the exhaust inlet side of the range hood. Generally, the range hood of the range hood differs depending on the manufacturer of the food and the manufacturer of the system kitchen equipped with the food.
In order to cope with the difference in the dimensions, a frame side portion having a substantially h-shaped cross section is attached to each pair of sides facing each other in a filter having a rectangular shape as a whole, and the outer side opposite to the filter for each frame side portion is attached. A desired number (arbitrary number) of auxiliary pieces each having an engaging portion that engages with the engaging protrusion on the side of the frame on the filter side and the same engaging protrusion on the opposite side of the filter. An attachment for a range hood filter that is sequentially engaged has been proposed (see, for example, Patent Document 1).

  However, in the case of the attachment for the range hood filter, it can be dealt with only by adjusting the dimensions outside the filter to be attached, in the same range as the width of the auxiliary piece, or in a range limited to an integral multiple of the width. However, there is a problem that it is not suitable for fine and accurate dimensional adjustment. Moreover, since it is necessary to sequentially engage the required number of auxiliary pieces in the field for each range hood, there is also a problem that a large amount of labor and time are required for the filter mounting operation.

The filter F and the fixed frame 50b are connected with the shortest distance by connecting the fixed frame 50b to the outside of the filter frame 2a.

Similarly to the above, when adjusting the distance between the filter F and the fixed frame 50b in the filter mounting frame 1e, for example, as shown in FIG. By fitting the wide concave groove 6b and the two wide convex ridges 58 located inside the fixed frame 50b individually and connecting the two, the distance between the filter F and the fixed frame 50b can be accurately determined. It becomes possible to expand (adjust) quickly.
In the filter mounting frame 1e, the outermost bottom wide groove 6b in the filter frame 2b and the innermost wide ridge 58 in the fixed frame 50b are fitted to each other, so that the filter frame 2b and the fixed frame 50b Can be expanded (adjusted) so that the distance between the filter F and the fixed frame 50b is fine, accurate, quick and easy.

  According to the second filter mounting frames 1d and 1e as described above, fine dimensional adjustment for each site such as a range hood, for example, is configured with only two types of filter frames 2a and 2b and fixed frames 50a and 50b. Depending on the number of members, it is fine, accurate, quick and easy, and it is possible to further reduce the labor and time for attaching the filter F.

The present invention is not limited to the embodiments described above.
For example, the wide groove may have a substantially Ω shape or an inverted T shape in cross section.
The wide ridge may have a substantially inverted Ω shape or T shape in cross section.
Furthermore, the board in the fitting frame has a form in which only two or one wide convex ridges are provided on the surface thereof, or two or one wide convex ridges, and 2 positioned alternately with these. One or three bottom wide concave grooves may be formed.
Moreover, the said filter frames 2a-2c change the thickness direction of the vertical piece 9 pinched | interposed into the said board | substrate 3 and the support piece 8 according to the thickness of the filter F which should be arrange | positioned. A plurality of types of dimensions may be prepared.
Furthermore, the filter F may have a substantially square shape in plan view, or may have a curved or curved shape in which the plan view has a rectangular shape or a square shape and is convex upward in a side view.
In addition, the filter mounting frame of the present invention can be applied not only to the ventilation path of a range hood in a kitchen such as a kitchen or a restaurant, but also to various types of air conditioning equipment or equipment for removing dust or dust. .

  According to the present invention, for example, it is possible to reliably provide a filter mounting frame that can accurately, quickly, and easily perform fine dimensional adjustment for each field of the range hood, and that can reduce the labor and time of the filter mounting operation.
