Abstract
An air cleaner includes an upper casing, which has an inlet, a lower casing, which has an outlet and covers the lower opening of the upper casing, and a filter element, which is located inside the upper casing and the lower casing. The lower casing includes a looped application surface, on which an adhesive is applied to adhere the filter element, and a minute protrusion, which extends along the perimeter, is formed on the inner peripheral edge of the application surface.
Claims8
An air cleaner casing, comprising:
- a bottom wall having an outer peripheral portion;
- a looped application surface, on which an adhesive is applied to secure a filter element, the looped application surface provided on the outer peripheral portion of the bottom wall;
- and
- a minute protrusion, which is formed on an inner side of the application surface to extend along a perimeter of the looped application surface,
- wherein the minute protrusion is configured to restrain the adhesive from moving inward, and
- wherein the filter element is to be located on the adhesive applied on the looped application surface, and
- a protrusion configured to be inserted in the adhesive applied on the looped application surface.
An air cleaner comprising:
- a first casing, which includes an opening and one of an inlet and an outlet;
- a second casing, which includes the other of the inlet and the outlet, wherein the second casing covers the opening of the first casing;
- and
- a filter element, which is located inside the first casing and the second casing, wherein
- the second casing includes:
- a bottom wall having an outer peripheral portion;
- a looped application surface, on which an adhesive is applied to secure the filter element, the looped application surface provided on the outer peripheral portion of the bottom wall;
- and
- a minute protrusion, which is formed on an inner side of the application surface to extend along a perimeter of the looped application surface,
- wherein the minute protrusion is configured to restrain the adhesive from moving inward, and
- wherein the filter element is located on the adhesive applied on the looped application surface;
- and
- the first casing includes a protrusion extending therefrom,
- wherein the protrusion is inserted in the adhesive applied on the looped application surface.
A method for manufacturing an air cleaner casing including a bottom wall having an outer peripheral portion, a looped application surface, on which an adhesive is applied to secure a filter element, the looped application surface provided on the outer peripheral portion of the bottom wall, the method comprising:
- molding the casing with a mold;
- and
- forming a minute protrusion, which extends along a perimeter of the looped application surface, on an inner side of the looped application surface with a parting surface of the mold when molding the casing, wherein the minute protrusion is configured to restrain the adhesive from moving inward, and
- wherein the filter element is to be located on the adhesive applied on the looped application surface, and
- forming a protrusion extending from the casing, wherein the protrusion is configured to be inserted in the adhesive applied on the looped application surface.
