Abstract

A dishwasher with an integrated closure element, such as a pivoting door or sliding drawer front, having a metallic front panel extending from an upper edge to a lower edge of the closure element includes a user interface located on an upper face of the closure element such that when the closure element is in a closed position, the user interface faces upwardly and is inaccessible to a user. A radio system for the dishwasher includes an upwardly facing antenna located on the closure element adjacent the user interface.

First claim

What is claimed is:

1. A dishwasher for treating dishes according to at least one automatic cycle of operation, the dishwasher comprising:
a housing;
a tub at least partially defining an open-faced treating chamber within the housing for receiving dishes for treatment according to the at least one automatic cycle of operation;
a closure element movable to selectively close the open face of the treating chamber, the closure element including a metallic front panel extending from an upper edge of the closure element to a lower edge of the closure element and a control console located at an upper end of the closure element behind the front panel;
a user interface associated with the console and located on an upper face of the closure element such that when the closure element closes the open face of the treating chamber, the user interface faces upwardly and is inaccessible to a user; and
an antenna located within the control console adjacent the user interface, wherein the antenna is adjacent the upper face of the closure element, wherein the antenna is directional and provides an upwardly-facing area of coverage when the closure element closes the open face of the treating chamber.

2. The dishwasher of claim 1 wherein the control console comprises a top plate forming the upper face of the closure element and a console body attached to the top plate, and the antenna is positioned between the top plate and the console body.

3. The dishwasher of claim 1 , further comprising an additional antenna located on a side of the dishwasher opposite the closure element.

4. The dishwasher of claim 3 wherein the additional antenna is mounted at a lower rear side of the dishwasher.

5. The dishwasher of claim 3 wherein the antenna and the additional antenna form part of a radio system further comprising a communication module with a radio in communication with the antenna and the additional antenna.

6. The dishwasher of claim 5 wherein the additional antenna is an onboard PCB antenna in the communication module.

7. The dishwasher of claim 5 wherein the antenna is coupled to the radio with a cable extending through the closure element and to the side of the dishwasher opposite the closure element.

8. The dishwasher of claim 5 wherein the combination of the antenna and the additional antenna provide WiFi signal coverage of nearly 360 degrees around the dishwasher with a minimum signal strength of about −17 dBi.

9. The dishwasher of claim 1 wherein the tub is metallic.

10. The dishwasher of claim 3 wherein the additional antenna provides a second area of coverage, wherein the upwardly-facing area of coverage and the second area of coverage together provide complete spherical antenna coverage around the dishwasher.
