Wave choke system for an oven door of a microwave oven

摘要

A wave choke system for an oven door of a microwave oven has an elongated channel for an outer portion of the oven door and an elongated cover sheet covering partially the width of an open longitudinal side of the channel. The cover sheet includes a plurality of slots extending perpendicular to the longitudinal axis of the cover sheet. Each slot includes an open end at a longitudinal edge of the cover sheet and a closed end on the opposite side of the open end, a broadening in a central portion of the slot, a first small portion between the open end and the broadening and a second small portion between the broadening and the closed end. The slots are reciprocally intersected, so that the contours of the slots and the intermediate pieces between the slots are formed complementarily to each other.

1. A wave choke system for an oven door of a microwave oven, comprising an elongated channel (10) provided for an outer portion of the oven door and an elongated cover sheet (12) covering partially the width of an open longitudinal side of said channel (10), wherein the cover sheet (12) includes a plurality of slots (14) extending perpendicular to the longitudinal axis of the cover sheet (12), each of the slots (14) includes an open end at a longitudinal edge of the cover sheet (12) and a closed end on the opposite side of said open end, each of the slots (14) includes a broadening (20) in a central portion of each of the slots (14), each of the slots (14) includes a first small portion (16) between the open end and the broadening (20), each of the slots (14) includes a second small portion (18) between the broadening (20) and the closed end, and the slots (14) are reciprocally intersected, so that the contours of the slots (14) and intermediate pieces (40) between the slots (14) are formed complementary to each other, wherein the first small portion (16) and the second small portion (18) of each of the slots (14) are collinear, wherein the width of the broadening (20) corresponds with the width of the intermediate piece (40) between the first small portions (16) and the second small portions (18) of two neighbouring slots (14).
