Abstract
Abstract A control valve assembly for an appliance includes a control valve and a swivel garden hose type connector for releasably connecting the fluid inlet of the control valve to external plumbing. The connector is securely and permanently affixed to a mounting bracket which is affixed to the cabinet of the appliance and is adapted for connection to the external plumbing by an internal thread. The integral connection of the connector and mounting bracket isolates the torque generated in securing the external plumbing to the connector and transmits the torque via the mounting bracket to the appliance cabinet. The swivel connector provides for ease in installation and/or replacement of the control valve. A grounding strap connected at one end to the control valve and to a predetermined location of the mounting bracket physically orients the fluid outlet of the control valve to a proper position for connection to a conduit which carries fluid from the control valve to a washing chamber of the appliance.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
A control valve assembly for controlling the flow of liquid supplied under pressure from external plumbing through a conduit to a washing area within the cabinet of an appliance, said control valve assembly comprising: an electrically operated control valve for selectively providing fluid communication between the external plumbing and the conduit; a swivel connector including a mounting bracket for attaching said connector to the cabinet, said mounting bracket including first and second portions, a fixed portion having a fluid passageway therein for connection to the external plumbing, said fixed portion connected to said first portion of said mounting bracket, and a movable portion releasably connecting said fixed portion in communication with said control valve; and grounding means connecting said control valve to the cabinet, said grounding means including an adjustable registration device orienting said control valve with respect to the cabinet and placing said control valve and the cabinet at the same electrical potential, said grounding means electrically connected to said control valve and including a portion commonly connected to the cabinet with said second portion of said mounting bracket.
Claim 2
Dependent Claim
180 words
A control valve assembly for controlling the flow of liquid supplied under pressure from external plumbing through a conduit to a washing area within the cabinet of an appliance, said control valve assembly comprising: an electrically operated control valve for selectively providing fluid communication between the external plumbing and the conduit; a swivel connector including a mounting bracket for attaching said connector to the cabinet, said mounting bracket including first and second portions, a fixed portion having a fluid passageway therein for connection to the external plumbing, said fixed portion connected to said first portion of said mounting bracket, and a movable portion releasably connecting said fixed portion in communication with said control valve; and grounding means connecting said control valve to the cabinet, said grounding means including an adjustable registration device orienting said control valve with respect to the cabinet and placing said control valve and the cabinet at the same electrical potential, said grounding means electrically connected to said control valve and including a portion commonly connected to the cabinet with said second portion of said mounting bracket.
Claim 3
Dependent Claim
36 words
A control valve assembly according to claim 1, wherein said control valve includes a threaded inlet and said movable portion is threaded and rotatably mounted on said fixed portion for threaded engagement with said threaded inlet.
Claim 4
Dependent Claim
32 words
A control valve assembly according to claim 1, wherein said mounting bracket is an L-shaped bracket with said first and second portions thereof extending at right angles with respect to each other.
Claim 5
Dependent Claim
192 words
A washing appliance including a cabinet, a washing chamber within the cabinet, an electrically operated fluid valve assembly having a fluid inlet for connection to external plumbing for providing fluid under pressure from a fluid source to said valve assembly and a fluid outlet, and an outlet conduit connecting said fluid outlet in communication with said washing chamber, said fluid valve assembly comprising: a control valve for controlling fluid flow therethrough to said washing chamber; a mounting bracket including a first portion, and a second portion attached to the cabinet; a fluid connector fixed to said mounting bracket and including a fixed portion connected to said first portion of said mounting bracket and coupled to the external plumbing, and a movable portion mounted on said fixed portion and operable to releasably engage said fluid inlet of said control valve; and a rigid conductive strap including a first portion electrically connected at one end to said control valve and a second portion electrically connected at the other end to the cabinet in common with said first portion of said mounting bracket for grounding and orienting said control valve with respect to said cabinet.
Claim 6
Dependent Claim
192 words
A washing appliance including a cabinet, a washing chamber within the cabinet, an electrically operated fluid valve assembly having a fluid inlet for connection to external plumbing for providing fluid under pressure from a fluid source to said valve assembly and a fluid outlet, and an outlet conduit connecting said fluid outlet in communication with said washing chamber, said fluid valve assembly comprising: a control valve for controlling fluid flow therethrough to said washing chamber; a mounting bracket including a first portion, and a second portion attached to the cabinet; a fluid connector fixed to said mounting bracket and including a fixed portion connected to said first portion of said mounting bracket and coupled to the external plumbing, and a movable portion mounted on said fixed portion and operable to releasably engage said fluid inlet of said control valve; and a rigid conductive strap including a first portion electrically connected at one end to said control valve and a second portion electrically connected at the other end to the cabinet in common with said first portion of said mounting bracket for grounding and orienting said control valve with respect to said cabinet.
Claim 7
Dependent Claim
50 words
A washing appliance as claimed in claim 4, wherein said fluid inlet of said control valve includes a threaded outer surface and said movable portion of said connector is rotatably mounted on said fixed portion and includes a female threaded portion for releasably securing said fluid inlet to said connector.
Claim 8
Dependent Claim
50 words
A washing appliance as claimed in claim 5, wherein said fixed portion of said connector includes internal threads for connection to the external plumbing, said fixed portion transmitting the torque required to secure the last-mentioned connection to said mounting bracket and cabinet and isolate such torque from said control valve.
