Claims20
A microwave oven with an antenna fixing system, comprising:
- a microwave oven having a cooking cavity with an antenna located adjacent to said cooking cavity;
- a stirrer motor having a rotating projection;
- a stirrer piece that includes an upward projection, a section that surrounds said rotating projection of said stirrer motor, and an opening;
- a spring member that includes a first extension that is received in said opening on said stirrer piece;
- a bearing base having an aperture;
- a ceramic support member having a first end section with a first diameter, a second end section with a second diameter, and a medial section with a third diameter that is larger than said first diameter and said second diameter forming a shoulder on said ceramic support member;
- an antenna support member that includes at least a portion that is received within said aperture in said bearing base, having an internal aperture that surrounds at least a portion of said first end section of said ceramic support member, said antenna support member having a surface that contacts at least a portion of one surface of said antenna and another surface that contacts said shoulder on said ceramic support member;
- and
- wherein a portion of said spring member is received in an opening in said ceramic support member.
