Abstract

A dish washer according to an embodiment of the present invention includes a cabinet which forms a dish washing space; a door which opens and closes an opened front surface of the cabinet; wherein door includes an out plate which is made of metal plate material and forms the front surface of the door and at least a portion of appearance of a peripheral surface of the door by being bent the front surface, an operating unit which is formed on the peripheral surface of the door so that a user operates by touch, a PCB assembly which is in close contact with a rear surface of the operating unit and on which a plurality of touch sensors detecting displacement of the operating unit are mounted, a mounting bracket which is mounted to be fixed to an inside surface of the out plate, and an elastic member which is mounted on the mounting bracket and presses and supports the PCB assembly to the a rear surface of the operating unit.

First claim

What is claimed is:

1. A dish washer, comprising:
a cabinet forming a dish washing space; and
a door which opens and closes a front surface of the cabinet;
wherein the door includes:
a metal out plate forming the front surface of the door and a peripheral surface of the door,
wherein the peripheral surface of the door is bent from the front surface of the door;
an operating part formed on the peripheral surface corresponding to a top of the door;
a back panel connected with the end of the peripheral surface to cover an inner space of the metal out panel and formed back surface of the door;
a mounting bracket mounted on the metal out plate inside the inner space;
a PCB assembly disposed on the mounting bracket and covered with the metal out plate;
a plurality of touch sensors disposed on the PCB assembly and contacted with the metal out plate to detect displacement of the peripheral surface; and
an elastic member disposed between the mounting bracket and the PCB assembly and supports the PCB assembly so that the touch sensors are in close contact with an inner surface of the peripheral surface forming a top surface of the door to detect displacement of the peripheral surface.

2. The dish washer of claim 1 , further comprising:
a display unit, for displaying operating information, disposed on a surface of the operating part corresponding to a position of each of the plurality of touch sensors.

3. The dish washer of claim 1 , wherein the mounting bracket is in contact with the front surface and the peripheral surface of the door.

4. The dish washer of claim 3 , further comprising:
a bending portion which is bent in the inside direction of the door on the peripheral surface, and
a screw hole which is formed so that a screw is passed through the bending portion,
wherein the screw is fastened to the mounting bracket and the bending portion and thus allows the mounting bracket to be fixed.

5. The dish washer of claim 1 , wherein an elastic member mounting portion which is formed in a shape corresponding to the elastic member and in which the elastic member is accommodated is formed on the mounting bracket.

6. The dish washer of claim 5 , wherein the elastic member mounting portion is formed by a mounting portion rib having a height which is less than the height of the elastic member.

7. The dish washer of claim 5 , wherein a reinforcing rib which supports the elastic member mounting portion from a lower side by extending to another surface of the mounting bracket which is in contact with a lower surface of the elastic member mounting portion is formed on the lower surface of the elastic member mounting portion.

8. The dish washer of claim 7 , wherein a plurality of reinforcing ribs are formed along the elastic member mounting portion and disposed to be parallel to each other with a fixed distance.

9. The dish washer of claim 1 , wherein a height of the elastic member is formed to be greater than a distance between a bottom surface of the elastic member mounting portion and the PCB assembly and the elastic member is maintained in a compressed condition to be applied elasticity of the elastic member toward the PCB assembly.

10. The dish washer of claim 1 , wherein the elastic member includes:
a rectangular shape of a support portion which is opened at the center thereof and which is protruded on a lower side corresponding to a region between the touch sensors, and
a connecting portion which connects the support portions.

11. The dish washer of claim 10 , wherein a center of the connecting portion is formed to be opened.

12. The dish washer of claim 10 , wherein the connecting portion is formed to be less than the height of the support portion.

13. The dish washer of claim 1 , wherein a display mounting portion, accommodating a display for displaying operating information of the dish washer, is formed in the mounting bracket, and
wherein a display unit which includes a plurality of first fine through-holes through which light emitted from the display is selectively transmitted is formed in the out plate corresponding to the display.

14. The dish washer of claim 13 , wherein a depression portion is formed on the upper surface of the mounting bracket and accommodates the PCB assembly.

15. The dish washer of claim 14 , wherein the depression portion includes:
the display mounting portion, and
an elastic member mounting portion which accommodate the elastic member by being disposed on the both sides of the display mounting portion.

16. The dish washer of claim 1 , wherein an indicator hole, in which a front indicator displaying an operation of the dish washer is mounted, is formed on the mounting bracket, and
wherein a through-hole through which light of the front indicator is transmitted is formed on the front surface of the door corresponding to the indicator hole.

17. The dish washer of claim 1 , wherein an LED is disposed on a side of each touch sensor in the PCB assembly, and
wherein a second through-hole is formed at a position corresponding to the LED in the operating part,
such that light from the LED is transmitted through the second through-hole.

18. The dish washer of claim 1 , wherein a handle for a turning operation of the door is provided on the front surface of the door,
wherein a tilting module which includes a push rod is provided on the mounting bracket, the push rod being selectively projected to the rear surface of the door and pushing the cabinet to open the door, and
wherein both ends of the handle is mounted on the tilting module by passing through the out plate and the mounting bracket to work with the push rod.

19. The dish washer of claim 1 , wherein the PCB assembly includes:
a sensor PCB which supports a periphery of the touch sensor;
a conductive foil which is provided on the front side of the sensor PCB and connects common contacts between the touch sensor and the sensor PCB with each other; and
a spacer which bonds the conductive foil and the sensor PCB while maintaining a fixed distance therebetween,
wherein a contacting portion which is projected to be in contact with the touch sensor is formed in the conductive foil.
