Abstract

An antenna fixing system for use in a microwave oven. The antenna fixing system includes a stirring piece, a ceramic support, and other components that couple an antenna to a stirrer motor while limiting unintentional movement of the antenna in multiple planes.

First claim

What is claimed is:

1 . 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.

2 . The microwave oven of claim 1 , including a spring cover that surrounds a portion of said spring member, said spring cover including an opening that is received around said second end section in said ceramic support member.

3 . The microwave oven of claim 2 , including a spring cover sponge that contacts a surface of said spring cover.

4 . The microwave oven of claim 1 , including a spring sheet that is located between the outer diameter of a portion of said first end section of said ceramic support member and the inner diameter of said internal aperture in said antenna support member.

5 . The microwave oven of claim 3 , including a waveguide housing with at least one bracket member for coupling to said stirrer motor.

6 . The microwave oven of claim 5 , wherein said waveguide housing includes a support opening that surrounds a portion of said second end section of said ceramic support member.

7 . The microwave oven of claim 6 , wherein said spring cover couples to the exterior lower surface of said waveguide housing adjacent to said support opening, with said spring cover sponge positioned between surfaces of said spring cover and said lower surface of said waveguide housing.

8 . The microwave oven of claim 7 , wherein said bearing base couples to the interior lower surface of said waveguide housing adjacent to said support opening.

9 . An antenna fixing assembly for a microwave oven, comprising:
an antenna; 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.

10 . The antenna fixing assembly claim 9 , including a spring cover that surrounds a portion of said spring member, said spring cover including an opening that is received around said second end section in said ceramic support member.

11 . The antenna fixing assembly of claim 10 , including a spring cover sponge that contacts a surface of said spring cover.

12 . The antenna fixing assembly of claim 9 , including a spring sheet that is located between the outer diameter of a portion of said first end section of said ceramic support member and the inner diameter of said internal aperture in said antenna support member.

13 . The antenna fixing assembly of claim 11 , including a waveguide housing with at least one bracket member for coupling to said stirrer motor.

14 . The antenna fixing assembly of claim 13 , wherein said waveguide housing includes a support opening that surrounds a portion of said second end section of said ceramic support member.

15 . The antenna fixing assembly of claim 14 , wherein said spring cover couples to the exterior lower surface of said waveguide housing adjacent to said support opening, with said spring cover sponge positioned between surfaces of said spring cover and said lower surface of said waveguide housing.

16 . The antenna fixing assembly of claim 15 , wherein said bearing base couples to the interior lower surface of said waveguide housing adjacent to said support opening.

17 . An antenna assembly for a microwave oven, comprising:
an antenna with a plurality of openings; 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; wherein a portion of said spring member is received in an opening in said ceramic support member; and a spring cover that surrounds a portion of said spring member, said spring cover including an opening that is received around said second end section in said ceramic support member.

18 . The antenna assembly of claim 17 , including a spring cover sponge that contacts a surface of said spring cover.

19 . The antenna assembly of claim 17 , including a spring sheet that is located between the outer diameter of a portion of said first end section of said ceramic support member and the inner diameter of said internal aperture in said antenna support member.

20 . The antenna assembly of claim 19 , including a waveguide housing with at least one bracket member for coupling to said stirrer motor, wherein said waveguide housing includes a support opening that surrounds a portion of said second end section of said ceramic support member.
