Abstract

An automatic dishwasher can include a tub having a bottom and at least partially defining an open face treating chamber, a base supporting the bottom of the tub and defining a mechanical area beneath the bottom of the tub, at least one sprayer emitting liquid into the treating chamber, and a rotating inlet filter assembly fluidly coupling the treating chamber to the at least one sprayer. A mounting bracket can be provided to secure the rotating inlet filter assembly to the base.

Claims (25)

1. An automatic dishwasher, comprising:

a tub having a bottom and at least partially defining a treating chamber;

a base supporting the bottom of the tub;

at least one sprayer emitting liquid into the treating chamber;

a recirculation circuit fluidly coupling the tub to the at least one sprayer;

a drain circuit fluidly coupling the tub to a household drain;

a pump assembly having a pump fluidly coupled to at least one of the recirculation circuit or the drain circuit, and a motor driving the pump; and

a mounting bracket, comprising:

a body coupled to the base;

an arm projecting at least horizontally from the body to form an L-shaped profile, the arm terminating in a distal end and having a flat upper surface supporting a portion of the pump assembly;

a gripping layer positioned between the arm and the portion of the pump assembly, the gripping layer having a plurality of ridges confronting the arm and forming hollow spaces along the flat upper surface of the arm; and

a bracket axis defined along the arm between the body and the distal end;

wherein the arm is configured to allow unconstrained motion of the portion of the pump assembly along the bracket axis.

2. The automatic dishwasher of claim 1 wherein the portion of the pump assembly comprises an outlet shaft, with the arm supporting the outlet shaft.

3. The automatic dishwasher of claim 1 wherein the gripping layer comprises vibration damping material.

4. The automatic dishwasher of claim 3 wherein the vibration damping material comprises at least one of EPDM, natural rubber, silicone, or plastic.

5. The automatic dishwasher of claim 1 wherein the plurality of ridges are spaced from each other by a spacing distance.

6. The automatic dishwasher of claim 5 wherein the spacing distance is greater than or equal to a height of the ridges.

7. The automatic dishwasher of claim 1 wherein the arm comprises at least one projection configured to carry the gripping layer.

8. The automatic dishwasher of claim 7 wherein the gripping layer comprises at least one through hole configured to receive the projection via an interference fit.

9. The automatic dishwasher of claim 1 , further comprising at least one degree of rotational freedom for the unconstrained motion such that the portion of the pump assembly rotates relative to the arm.

10. The automatic dishwasher of claim 1 , further comprising at least one degree of freedom for the unconstrained motion that is a combination of translational and rotational freedom.

11. The automatic dishwasher of claim 1 wherein the pump further comprises a centrifugal pump having an impeller rotationally driven by the motor.

12. The automatic dishwasher of claim 1 wherein the pump comprises at least one of a recirculation pump, a rotating inlet filter, or a drain pump.

13. The automatic dishwasher of claim 1 , further comprising at least one degree of translational freedom for the unconstrained motion such that the portion of the pump assembly translates relative to the arm.
