摘要： A water heater may include a water tank, a burner, a pilot for igniting the burner, an ignitor for igniting the pilot, a thermoelectric device in thermal communication with a flame of the pilot, a controller for controlling an ignition sequence of the pilot using the ignitor, and a rechargeable power storage device for supplying power to the ignitor and the controller. The rechargeable power storage device may be rechargeable using the energy produced by the thermoelectric device. The controller is configured to selectively run only the pilot for at least part of a heating cycle to increase the recharge time of the rechargeable power storage device while still heating the water in the water heater.

摘要： A system for heating water to improve safety and efficiency. The system may have normal operation measured in time. After a time of normal operation, a water temperature setpoint may be checked. If the setpoint is not at a certain level, normal operation may continue. If the setpoint is within the certain level, water temperature may be measured. If the water temperature is less than a desired level, one or more draws of water may be measured for a preset temperature drop. If the draws do not meet the temperature drop, a return to check the setpoint may be made. If the draws meet the temperature drop, the setpoint may be reduced and a time of normal operation may be measured to determine whether a burn cycle occurs within the time. If not, normal operation may continue; but if so, a return to check the setpoint may be made.

摘要： This disclosure is related to devices, systems, and techniques for outputting an alarm signal in response to detecting a leak in a water heater device. For example, a water heater device includes a leak sensor, an intermittent pilot light, and a circuit. The circuit includes processing circuitry configured to receive, from the leak sensor, an electrical signal including information indicative of a leak in the water heater device, activate, based on the electrical signal including information indicative of the leak, an alarm device, where the alarm device is powered for at least a period of time by a power source, where the power source is configured to receive energy from a thermoelectric device, and maintain an amount of energy stored by the power source so that the amount of energy is sufficient for the power source to supply energy to the alarm device.

摘要： A water heater control system the water heater system comprising a rechargeable and non-rechargeable power source. In one or more examples, a controller such as a microcontroller of the water heater system is configured to receive power from the non-rechargeable power source and does not receive power from the rechargeable power source. Various other components of the water heater system are configured to receive power from the rechargeable power source. The system may comprise an energy storage system electrically connected to a pilot valve operator and electrically isolated from a main valve operator. The controller may be configured to recognize a call for main burner operation and may also be configured to check an available voltage of the energy storage system against a setpoint.

摘要： The disclosure reveals a system for detecting moisture or water in a particular location. The system may incorporate a moisture detector having a control module connected to an appliance, a moisture detection circuit connected to the control module, and a voltage source connected to the moisture detection circuit and to the control module. The voltage source and the moisture detection circuit may provide voltage levels to the control module when the moisture detection circuit detects dry or wet conditions, or conditions between those conditions. A voltage level to the control module may indicate whether the appliance, such as a water heater, a washing machine, or a dish washer, has a leak. If the leak is deemed by a voltage level from the circuit to be worthy of concern, then a display, an alarm, message, or other notice mechanism may indicate an issue or what action needs to be taken.

摘要： A gas valve actuator for a gas valve. The gas valve actuator includes a non-conductive support bobbin and an insulated copper wire wound about the support bobbin to form a coil. A magnetic flux concentration member extends through the non-conductive support bobbin. To actuate the gas valve actuator, a current is passed through the coil, which produces a magnetic field that actuates an armature to move a valve seal away from a valve seat of the gas valve. Because the gas valve actuator may be exposed to a gas stream, the coil may be coated with an anti-corrosion coating through a spray or brush process, a potting process, through a dipping process, or in any other suitable manner.

摘要： A gas valve assembly configured to operate without a pilot assembly is disclosed. In an illustrative embodiment, a servo valve actuates a diaphragm valve to selectively allow for fluid coupling of a gas inlet and gas outlet. The diaphragm valve may be a normally closed valve that opens in response to a pneumatic force resulting from the opening of the servo valve.

摘要： Apparatus and method for mounting a non-immersion type temperature sensor to a tank, such as a water heater tank, that is designed for an immersion-type temperature sensor. In one example, a mounting adaptor may include a proximal cavity extending from a proximal end toward a distal end and a distal cavity extending from the distal end toward the proximal end. A wall fluidly isolates the proximal cavity from the distal cavity. The mounting adaptor is mounting to the mounting spud of an immersion type water heater tank, such that the distal cavity of the mounting adaptor is filled with water from the water heater tank. A non-immersion type temperature sensor is positioned adjacent to or in the proximal cavity and in thermal communication with the water in the distal cavity.
