摘要:
Heating device having a substantially flat heating element with specifically selected physical parameters is provided for heating an object to a required temperature. The physical parameters are selected such as to, at a given power and at a selected voltage supply to the heating element, provide as low as desired temperature gradient between the temperature of the outer surface of the heating element through which heat is dissipated and the required temperature of the object. Heating devices of the invention may be implemented in domestic heaters, in food cooking devices, in medical devices, etc. Also provided is a method for designing heating elements for use in such devices.

A water filter device has a collecting pot (1) with a spout (2) disposed at the front, with a handle (3) disposed at the rear in opposite relationship, and with an electrical heating element (5) arranged in the lower boiling region of the collecting pot (1), in this arrangement the collecting pot (1) is closable at the top by a lid (4) and provided in the interior is a filter insert (8) in which a filter cartridge (9) which can be filled with a purification agent is arranged so that untreated water can be poured into the filter insert (8) by way of the filter cartridge (9) and can pass due to the force of gravity to at least under the filter cartridge (9). The filter insert (8) is arranged in an insulating insert (6) in such a way that provided between the boiling region at the bottom in the collecting pot (1) and the filter insert (8) with the filter cartridge (9) is a partition wall (10, 10a) which is generally arranged at a spacing from the filter insert (8) and which is at least partially in the form of a horizontally extending plate. Provided in the lower region of the insulating insert (6) is a through opening (7) for the connection between the discharge end of the cartridge (9) and the collecting pot (1). So that such a water filter device can be simplified to the effect that the filter insert (8) can be removed separately from the insulating insert (6), in which case the inserts (6, 8) can be better cleaned, the pouring properties of the pot are improved and operation of the device can be better adapted to different amounts of water to be purified, it is provided in accordance with the invention that the through opening (7) is arranged in the rear region (D) of the collecting pot (1) which is in opposite relationship to the spout (2), the substantially horizontally extending part (10a) of the partition wall (10) is inclined rearwardly relative to the through opening (7) and extends above the boiling region at least partially over the cross-section of the collecting pot (1).
摘要:
The invention comprises a hot water heater system including a hot water tank, a hot water heater; a pressure relief device which is activated when the hot water heater system is in an overpressure or over-temperature condition; a relief line which is engaged when the pressure relief device is activated; and an output device for providing indicia that the pressure relief device is activated. According to other embodiments, the invention includes means for interrupting or reducing water intake and/or power to the system when in an overpressure or over-temperature state.

The invention relates to an LPG combusting burner device for flaming and flame cultivation purposes and an improved hand-held torch that may incorporate such burner device. The burner device includes a primary burner (14) having at least one fuel delivery nozzle or jet (80) arranged within an open combustion chamber (71) defined within a burner skirt (70) such as to direct a stream of fuel towards a flame delivery opening of the skirt (70), and a vaporiser (18) located in heat exchanging proximity to the primary burner (14) and having a pressurization chamber with an inlet for liquid LPG fuel and an outlet for gaseous LPG fuel, the inlet being arranged to be in fluid communication with a source of pressurized LPG and the other being in communication with the nozzle of the primary burner. A metering duct (37) is located in close vicinity or within the vaporiser (18) and arranged to discretely limit the amount of liquid fuel entering the vaporisation chamber via its inlet, and a first pressure reduction duct (52) is provided in the flow path of gaseous fuel between the vaporisation chamber outlet and the nozzle of the primary burner (14) the first pressure reduction duct (52) arranged to impart a discrete pressure drop to gaseous fuel flowing therethrough between the vaporisation chamber (50) and the nozzle of the primary burner (14), the discrete pressure drop being such as to generate a low velocity combustion flame in the primary burner (14) during normal burner operation.

摘要:
An apparatus and a method for preventing fire in a liquid heating tank that utilizes resistive heating elements for raising the temperature of a flammable liquid are described. In the apparatus, a buffer tank is provided which is positioned under a process tank that heats the flammable liquid. The buffer tank is equipped with a thermocouple for detecting the temperature of fluid flown therein and an air actuated solenoid valve for shutting off a drain pipe from the buffer tank. When a higher temperature is sensed by the thermocouple, i.e. caused by the mixing of the higher temperature process liquid and the lower temperature water, the air solenoid valve is shut off to cause a back flow of the processed liquid/water mixture into the process tank and thus keeping the heating elements submerged in the processed liquid/water mixture. Any possible exposure of a hot surface of the resistive heating elements to ignite flammable vapor or liquid is thus prevented and a potential fire is avoided.

A water heater that includes a tank, an electrical component, and an electrical circuit. The tank defines a water chamber and includes an outer surface. The electrical component is coupled to the outer surface of the tank and extends from the outer surface of the tank. The electrical circuit electrically connects the electrical component and provides electricity to the electrical component when the electrical circuit is closed and does not provide electricity to the electrical component when the electrical circuit is open. A door assembly is movable between an open position and a closed position, and the door assembly includes a connecting device mounted to the door assembly. The connecting device closes the electrical circuit when the door assembly is in the closed position and opens the electrical circuit when the door assembly is in the open position.
