Abstract

Provided is a cooking apparatus and a touch sensor assembly of the cooking apparatus, including an outer cover formed of a metal material and forming an exterior of the cooking apparatus; and a touch module mounted on a rear side of the outer cover to be contacted therewith and including a plurality of touch sensors, wherein a touch unit is formed in an opening of a rear side of the outer cover that contacts to the touch sensor and is elastically deformed with ease when touched by a user to transfer the pressure to the touch sensor.

First claim

What is claimed is:

1 . A control assembly, comprising:
a cover plate; a printed circuit board having a touch sensor attached thereon, the printed circuit board being provided at a rear side of the cover plate; a bonding member that bonds the cover plate with the printed circuit board; a body panel that receives the printed circuit board, the body panel being attached to the cover plate; and a printed circuit board opening through which the printed circuit board is inserted into the body panel, the printed circuit board opening having the same shape as a circumference of the printed circuit board.

2 . The control assembly of claim 1 , wherein the shape of the printed circuit board corresponds with the shape of the printed circuit board opening, the shapes being asymmetrical in the vertical and horizontal directions.

3 . The control assembly of claim 1 , further comprising:
a knob mounting unit provided at the body panel through which a rotational axis of a knob passes, the knob mounting unit having a portion that projects inside the printed circuit board opening.

4 . The control assembly of claim 3 , wherein a side of the circumference of the printed circuit board comprises a parting unit bent in a shape corresponding to a shape of the knob mounting unit.

5 . The control assembly of claim 3 , wherein a vertical width of an upper area of the printed circuit board opening is different than a vertical width of a lower area of the printed circuit board opening.

6 . The control assembly of claim 3 , wherein the body panel further comprises a knob printed circuit board provided at an inner side of the body panel, the knob printed circuit board being coupled with the rotational axis of the knob.

7 . The control assembly of claim 3 , wherein a lower end of the printed circuit board opening comprises a printed circuit board supporting unit that supports the printed circuit board.

8 . The control assembly of claim 1 , wherein the body panel further comprises a supporter that presses against and supports the printed circuit board such that the printed circuit board contacts a rear side of the cover plate.

9 . The control assembly of claim 8 , wherein the supporter is formed of an elastic material.

10 . The control assembly of claim 8 , wherein the supporter comprises:
a base having a plate-like shape that corresponds to the printed circuit board; and a plurality of supporting parts that project from the base, the supporting parts corresponding to the touch sensors and supporting an area of the printed circuit board corresponding to a circumference of each of the touch sensors.

11 . The control assembly of claim 10 , wherein a plurality of reinforcing ribs that form a lattice are provided at a side of the base that is opposite to the supporting part.

12 . The control assembly of claim 10 , wherein the supporting part includes:
a rib that is provided along the circumference of the touch sensor; and a plurality of projections that are provided along the rib at regular intervals, the plurality of projections being projectedly formed to contact the printed circuit board.

13 . The control assembly of claim 12 , wherein the diameter of the rib is greater than or equal to the diameter of the touch sensor.

14 . The control assembly of claim 12 , wherein an operating unit and the touch sensor formed at the cover plate are positioned at an interior area of the rib.

15 . The control assembly of claim 14 , wherein a center of the operating unit is linear with a center of the touch sensor formed at the cover plate and the supporting part.

16 . The control assembly of claim 10 , wherein the printed circuit board includes a printed circuit board connector connected to a wire, and
the supporter has a connector hole that exposes the printed circuit board connector.

17 . A cooking apparatus having a control assembly, comprising:
a body that forms a cooking space; a door that is attached to the body; and a control assembly provided at the front side of the body, wherein the control assembly includes: a cover plate; a printed circuit board having a touch sensor attached thereon, the printed circuit board provided at a rear side of the cover plate; a bonding member that bonds the cover plate with the printed circuit board; a body panel that receives the printed circuit board, the body panel being attached to the cover plate; and a printed circuit board opening through which the printed circuit board is inserted into the body panel, the printed circuit board opening having the same shape as a circumference of the printed circuit board.

18 . The cooking apparatus of claim 17 , wherein the cover plate is formed of a metallic material.

19 . The cooking apparatus of claim 17 , wherein the body panel is coupled with a front portion of the body, and a front portion of the door and a front portion of the cover plate are positioned along the same plane.

20 . The cooking apparatus of claim 19 , further comprising:
a plurality of fixtures that are projectedly formed along a circumference of the cover plate; and a plurality of fixture grooves that are formed at the body panel, the fixtures being bent and received in the fixture grooves.

21 . The cooking apparatus of claim 19 , further comprising stepped parts that are in contact with an upper end and a lower end of the cover plate, the stepped parts being formed at an upper end and a lower end of the body panel, wherein the cover plate is received between the stepped parts.

22 . The cooking apparatus of claim 19 , wherein a shape of the printed circuit board corresponds with a shape of the printed circuit board opening, the shapes being asymmetrical in the vertical and horizontal directions such that the printed circuit board can be inserted into the printed circuit board opening in a single direction.

23 . The cooking apparatus of claim 19 , wherein the body panel further comprises a supporter that presses against and supports the printed circuit board such that the printed circuit board contacts a rear side of the cover plate.
