A hot water dispensing system comprises a one-piece plastic tank having a main heating chamber, an expansion chamber, and an air collection chamber. The air collection chamber is disposed generally below the expansion chamber and alongside the main heating chamber. The main heating chamber is in fluid communication with the expansion chamber and the air collection chamber. The hot water dispensing system also includes a temperature control system having a heating element, a metal temperature sensing bracket, and a thermostat. The heating element is disposed within the plastic tank and connected to a metal temperature sensing bracket disposed outside the tank. The excellent conductive properties of a metal sheath that connects the metal temperature sensing bracket to the heating element allow the metal temperature sensing bracket to simulate changes in the temperature of water in the tank. The thermostat is mounted to the metal temperature sensing bracket and measures a temperature of the metal temperature sensing bracket and activates or deactivates a heating element in response to the measured temperature of the metal temperature sensing bracket.

One-piece plastic tank and temperature control system for a hot water dispenser

A hot water supply system has a tank divided into a water heating chamber and a vented expansion chamber. A venturi orifice inlet is connected through a faucet valve to a cold water supply and the outlet of the orifice emits a high velocity jet at a negative pressure to cause water to be aspirated from the expansion chamber and mix with the supply water jet for pressurizing the heating chamber to cause hot water to be dispensed from the faucet spout, connected to the tank heating chamber, when the valve is opened. An air collection chamber receives the supply water jet stream which flows into the heating chamber until the expansion chamber is emptied of water for air to be aspirated into the collection chamber in which case the jet is disrupted and aspiration of air stops although the flow of water into and out of the heating tank can continue as long as the faucet valve remains open.

An organic waste disposer 10 such as is commonly mounted to a kitchen sink 12 has mounted next to it a device 14 for injecting a predetermined quantity of bio-enzyme material into the disposer's grinding chamber each time the motor of the disposer is turned on.

Apparatus for comminuting organic waste and injecting bio-enzymes into

A grinder for dry waste materials such as rubber gloves has a vertically-oriented, cylindrically-shaped housing with an opening at its upper end for receiving materials to be comminuted. The housing is divided into upper and lower chambers by means of a rotatable, disk-shaped shredder element. The shredder element has a pair of parallel upwardly-extending impeller blades disposed on its upper surface on opposite sides of its center of rotation which define a channel across the diameter of the shredder element.

A grinder for dry waste materials includes a vertically-oriented, cylindrically-shaped housing having an opening at its upper end for receiving materials to be comminuted. The shredder element has upwardly-extending impeller blades disposed on its upper surface. The outer perimeter of the shredder element is separated from the inner wall of the housing sufficiently to provide a gap through which comminuted materials can drop from the upper chamber to the lower chamber of the housing. The interior of the upper portion of the housing is provided around its circumference with diverget blades that are angled downwardly in the direction of rotation of the shredder element. The lower housing has a closed bottom and a tangentially oriented discharge element for discharge from the lower housing of comminuted materials. The shredder element has downwardly-extending paddles on its lower surface that extend downwardly into the lower housing and are adapted to sweep the lower housing, act as an air blower and expel comminuted materials therefrom. Optionally the shredder element is flattened on opposite sides, to provide enlarged openings for movement of comminuted materials from the upper chamber into the lower chamber. The upwardly-extending impeller blades may optionally be Z-shaped.

Dry waste grinder

A waste disposer having a rotatable shredding element for grinding waste in a flushing liquid, an outlet for discharging ground waste material in liquid to a drain, an electrically-powered motor for driving the rotatable shredding element and a source for supplying flushing liquid the disposer that includes a detector for sensing the amount of electrical current flowing to the motor. The system includes, at least, one valve for controlling the flow of flushing liquid to the disposer which valve is controlled by means of a controller that is responsive to the electrical current detector. The controller increases the amount of flushing liquid falling into the disposer in response to a detected increase in the amount of electrical current flowing into the motor. The invention optionally includes a second valve for controlling flushing liquid to the disposer at a lower rate, which second valve is opened whenever the electrical is activated. Both of the controllers may be solenoids, but the first-mentioned controller may also be a progressively activated servo motor that progressively increases the flow of water to the disposer as the electrical current usage increases.

Water saver control for disposers

An instant hot water dispenser has an upper plastic tank section connected to a lower brass tank section by a safety clamping arrangement which includes outturned tabs on the upper plastic tank section which interfit in notches in the brass lower tank section and a retainer ring located between the plastic tabs and outturned metal flanges on the brass tank section. An O-ring seal between the plastic upper tank and the brass tank provides a fluid seal. Various of the plumbing connections are integrally molded with the plastic top and expansion chamber cover which is separated from the main water tank by a common wall or partition. An aspirator opening in an integrally formed plastic stem in the expansion chamber cover aspirates water from the expansion chamber as incoming cold water passes the aspirator opening.
