US 3,941,153 A · Water inlet device for controlling flow to an appliance

Abstract

A water inlet device for an appliance having a cabinet containing a washing chamber characterized by a connector housing having a cavity receiving a diaphragm valve coacting with a valve seat on a port to control flow through the cavity with the operation of the diaphragm valve being controlled by a pilot valve disposed in the appliance. The water inlet device is particularly adapted for portable appliances and preferably has means for forming a quick connection to a source of water. The diaphragm is provided with at least one orifice to allow the source of water to bleed into a pressure chamber to bias or urge the diaphragm valve to a closed position and the pilot valve selectively bleeds this pressure chamber to cause a pressure differential on the diaphragm to selectively open the valve to admit water to the washing chamber of the appliance.

Dependent claims

An appliance having a cabinet containing a washing chamber, and a water inlet system for connecting the washing chamber to a source of water which is located outside of the cabinet, the water inlet system comprising:

a coupler having seal means for sealingly connecting the coupler to the source of water;
an inlet conduit fluidly connecting the coupler to said washing chamber;
a diaphragm valve means within the coupler for controlling the flow of water from said source through the inlet conduit;
a bleed tube line forming a separate passageway fluidly connecting the diaphragm valve means to the washing chamber;
and
a control means in said bleed tube line, said control means being housed within the cabinet and selectively operable to control flow in the bleed tube line to control operation of said diaphragm valve means.

A water inlet device for an appliance having a cabinet containing a washing chamber, said inlet device comprising:

an outer housing having a cavity with an inlet port and an outlet port;
means disposed in said housing for sealingly connecting the inlet port to a source of water under pressure which source is located outside of the cabinet;
an inlet conduit fluidly connecting the outlet port of the cavity to the washing chamber;
diaphragm valve means disposed in said cavity for controlling the flow of water through said outlet port;
a control conduit forming a separate passageway fluidly connected to the diaphragm valve means and extending to the washing chamber in the cabinet of the appliance;
and
control means disposed in the cabinet and connected to said control conduit for selectively controlling fluid flow therein to control the operation of the diaphragm valve means so that the diaphragm valve means selectively opens and closes the outlet port in response to a control signal transmitted by the fluid flow in the control conduit.
