Description

[Detailed Description of the Invention] The present invention relates to a device for removing oil stains attached to the inner surface of a range hood or the like.

Conventional range hoods had the disadvantage that if the inside surface became dirty with oil, the range hood itself could not be completely cleaned even if it was removed, soaked in detergent, and washed with a scrubbing brush.

The purpose of the present invention is to provide a range hood oil stain removal device to eliminate the above-mentioned drawbacks.

Embodiments of the present invention will be described below based on the drawings.

The main body of the range hood 1 is made up of a tetrahedron formed by welding or connecting four metal plates with rivets, small screws, etc., and the air intake port 2 is vented through a duct 3 to a ventilation fan (not shown).

An aluminum foil laminated sheet 4 is attached to the entire inner surface of this range hood 1. The structure of this aluminum foil laminated sheet 4 is such that the thickness of one sheet is, for example, 20μ~
It is made by laminating many sheets of 40μ aluminum foil, for example, 10 to 50 sheets, and has a total thickness of 1 to 2 mm, with holes drilled at appropriate intervals for stretching the foil, and Perforations 5 are formed in advance on two opposing sides.

Such an aluminum foil laminated sheet 4 is held at its periphery by a sheet retaining frame 6 provided along the periphery of the tetrahedron of the range hood 1, and is screwed into a female thread 8 carved in the range hood body or reinforcing frame. It is fixed by matching machine screws 7. When attaching this aluminum foil laminated sheet 4 to the inner surface of the range hood, the entire back surface or the periphery may be attached using a heat-resistant adhesive or adhesive.

In addition, in order to make it easier to peel off the aluminum foil, a fifth
As shown in the enlarged drawing, tongue-shaped tabs 9...9 may be provided for each sheet of aluminum foil. This knob portion 9 is preferably provided near the end of the perforation.

Next, an example of the use of the present invention will be explained.

Water vapor containing oil and fat generated from food cooked in a gas range, fryer, etc. passes through the intake hole along the aluminum foil laminated sheet on the inner surface of the range hood, and is discharged to the outside air by a ventilation fan through a duct.

At this time, dirt containing oil and fat adheres to the surface of the aluminum foil laminated sheet of the present invention.

Depending on the degree of oil stains, remove one layer every March or every year. This peeling also removes the oil and fat that had adhered to the inner surface of the range hood, exposing the new aluminum foil.

FIG. 6 shows another embodiment of the present invention.

A serrated plate is attached to the inside of the sheet retaining frame 6 so that the serrated part is exposed outside the frame, and the aluminum foil laminated sheet 4 has two sides 11 and 12 across which the serrated part is not provided. Two parallel perforations 13 and a knob 14 are formed in advance at one end of the perforations 13.

When peeling aluminum foil using this, first, peel off the strip along the perforation 13 from the tab 14, then peel off the left and right halves, and cut with the serrated plate 10.

According to the present invention, since the inner surface of the range hood body etc. is covered with a pre-fabricated laminated sheet of metal foil, it is possible to peel and renew dozens to dozens of times even though the sheet is only 1 to 2 mm. Because it is highly heat resistant, there is no risk of causing a fire, and it can be installed simply by mechanically fixing the sheet periphery to the sheet retaining frame, so it can be easily attached to the main body of a ready-made range hood, etc. Since each foil is provided with a peeling means such as perforations, oil stains can be removed quickly and hygienically.

The present invention can be applied not only to the inner surface of the range hood but also to the inner surface of the duct.
