International Classification:

H05B 3/02
F24H 1/18
G05B 15/00

US Classification:

219481, 392449, 700275

Abstract:

A dry fire protection system for a water heater is provided. The water heater includes a body having an elongated hollow for holding water to be heated, an inlet opening and an outlet opening in communication with the hollow for flowing water therethrough. A heating element is coupled to the body for heating the water within the hollow. The dry fire protection system comprises a sensing element disposed in the hollow of the body for detecting the presence of water in the hollow. The sensing element is spaced from and operably connected to the heating element. The sensing element is configured to generate a voltage in response to a temperature of the sensing element. A controller is operably connected to the sensing element for monitoring the generated voltage across the sensing element. The controller is configured to prevent a supply of electrical power to the heating element as a function of the generated voltage.

International Classification:

G05D 23/13
F16K 11/044

Abstract:

A mixing valve for a water heater appliance includes a valve body that defines a mixing chamber, the mixing chamber being in fluid communication with a cold water inlet conduit and a hot water inlet conduit. The cold water inlet conduit defines a profiled junction defining an inlet orifice and a plunger valve is mounted within the valve body and is moveable relative to the inlet orifice to regulate a flow of water through the inlet orifice. A distal end of the plunger valve defines a profiled sealing face, the profiled sealing face and the inlet orifice being cooperative to permit a flow rate that is substantially proportional to a valve position.

International Classification:

F24H 9/20
F24H 1/20
F24H 9/18

Abstract:

A method for operating a water heater appliance includes determining a set temperature of the water heater appliance. The method also includes monitoring a temperature proximate to a lower heating element of the water heater appliance with a first temperature sensor of the water heater appliance and monitoring a temperature proximate to an upper heating element of the water heater appliance with a second temperature sensor of the water heater appliance. When the monitored temperature proximate the lower heating element is less than a first temperature threshold and the monitored temperature proximate the upper heating element is less than a second temperature threshold, the method includes turning the lower heating element on. When the monitored temperature proximate the upper heating element is equal to the set temperature, the method includes turning the lower heating element off. A related water heater appliance is also provided.

- Schenectady NY, US
Christopher Bryan Rissler - La Grange KY, US
Jonathan D. Nelson - Louisville KY, US

International Classification:

F24H 9/06
F24H 9/02

Abstract:

A water heater appliance includes a support pad positioned on an outer shell of the water heater appliance. A pair of inserts is disposed within the support pad. Each insert of the pair of inserts is positioned on a respective one of an inlet conduit and an outlet conduit of the water heater appliance. The inserts have a density greater than the support pad.
