Claims:1. A multi-air flow (MAF) assembly (10) in a household appliance (11), said
MAF assembly (10) comprising :
- an inner component (12) having a projection (5 14) at one end and
multiple vents (16) for air flow between compartments (18(a),18(b)) of
said appliance (11);
- an outer component (20) enclosing said inner component (12);
characterized in that :
10 said inner component (12) comprises a lining (22) made of an
expandable polystyrene, In-molded to said outer component (20).
2. The MAF assembly (10) as claimed in claim 1,wherein said outer component
(20) is made of thermo plastic polymer and has dimensions corresponding
15 to dimensions of said inner component (12).
3. The MAF assembly (10) as claimed in claim 2, wherein said outer component
(20) is vacuum formed and trimmed corresponding to said dimensions of
said inner component (12), before In-molding onto said inner component
(20).
4. The MAF assembly (10) as claimed in claim 3, wherein said vacuum formed
and trimmed outer component (20) is placed in a pre-determined position in
a mold (24).
25
5. The MAF assembly (10) as claimed in claim 4, wherein said vacuum formed
and trimmed outer component (20) placed in said mold (24), is IN-molded
with said lining of said inner component (12) to form said Multi-air flow
assembly (10).
6. The MAF assembly (10) as claimed in claim 5, wherein due to In-molding of
said inner component (12) with said outer component (20), a movement of
said air flowing in between of said inner component (12) and said outer
component (20) is sealed.
7. The MAF assembly (10) as claimed in claim 1, comprises a supporting
element (26) fitted into said projection (14) of said inner component (12)
after, said outer component (20) In-molded onto said inner component (12).
8. The MAF assembly (10) as claimed in claim 1, wherein outer component (20)
and said inner component (12) is made as a single part in said appliance (11),
by In-molding said inner component (12) with said outer component (20). , Description:The MAF assembly 10 comprises an inner component 12 having a projection 14 at one
end and multiple vents 16 for airflow between compartments (18(a), 18(b)) of the
appliance 11. The assembly 10 comprises an outer component 20 enclosing the inner
component 12. The inner component 12 comprises a lining 22 made of an expandable
polystyrene, In-molded with the outer component 20. The In-mold process not only
provides the less manufacturing cost, but also provides the efficient flow of air from one
compartment 18(a) to other compartment 18(b) in the appliance 10.
