Abstract

Abstract An automatic ice-making system for use with a bottled water supply includes a refrigeration unit having a freezer section for receiving and freezing water. An enclosed reservoir for bottled water is provided with the refrigeration unit, a feed line being established between the reservoir and the freezer section. A valve is interposed in the feed line for controlling the flow of water through the feed line between the reservoir and the freezer. A pump is provided with the reservoir for pumping water through the feed line. A specific electrical contact configuration provides means for simultaneously energizing the pump and commencing the opening of the valve, responsive to a sensed condition in the freezer. The preferred configuration of the reservoir is a flat, generally U-shaped container, with the pump being positioned within an enclosure located within the confines of the U-shaped container.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 220 words
An automatic ice-making system for use with a bottled water supply comprising: (a) a refrigeration unit including a freezer section for receiving and freezing water, said freezer section including a sensor element for providing an output indicating a demand for additional water; (b) an enclosed reservoir for bottled water adjacent to said refrigeration unit, said reservoir comprising a generally flat container having a U-shaped indentation therein; (c) a pump positioned within said U-shaped indentation and having a feed line formed of a relatively rigid tube extending into the bottom of said container and in communication with said pump; (d) a solenoid valve having an input coupled to a water output of said pump and having an output coupled to said freezer section of said refrigeration unit; (e) a first circuit wire pair coupled between said pump and said solenoid valve, said first circuit wire pair including piggyback prong connectors at the juncture with said valve; (f) a second circuit wire pair coupled between said sensor element in said freezer section and said piggyback connectors of said first circuit pair and wherein (g) the sensing of a demand for additional water by said sensing element permits the simultaneous energizing of said pump and the opening of said valve, to permit water to be pumped from said container into said freezer unit.
Claim 2
Dependent Claim 220 words
An automatic ice-making system for use with a bottled water supply comprising: (a) a refrigeration unit including a freezer section for receiving and freezing water, said freezer section including a sensor element for providing an output indicating a demand for additional water; (b) an enclosed reservoir for bottled water adjacent to said refrigeration unit, said reservoir comprising a generally flat container having a U-shaped indentation therein; (c) a pump positioned within said U-shaped indentation and having a feed line formed of a relatively rigid tube extending into the bottom of said container and in communication with said pump; (d) a solenoid valve having an input coupled to a water output of said pump and having an output coupled to said freezer section of said refrigeration unit; (e) a first circuit wire pair coupled between said pump and said solenoid valve, said first circuit wire pair including piggyback prong connectors at the juncture with said valve; (f) a second circuit wire pair coupled between said sensor element in said freezer section and said piggyback connectors of said first circuit pair and wherein (g) the sensing of a demand for additional water by said sensing element permits the simultaneous energizing of said pump and the opening of said valve, to permit water to be pumped from said container into said freezer unit.
Claim 3
Dependent Claim 30 words
