摘要:
A method for controlling a cooking device includes detecting a temperature of a door on the cooking device, comparing the detected temperature with a predetermined warning and/or reference temperature, generating a predetermined warning if the detected temperature is equal to or higher than the predetermined warning and/or reference temperature, and outputting the predetermined warning.

An electronically controlled burner (2) configured to combust bioethanol, which electronically controlled burner (2) comprises at least one fuel tank (6) being in fluid communication with an evaporation accelerator (10) being in thermal contact with a heating element (12) configured to heat and hereby evaporate fuel in the evaporation accelerator (10), a flame tray (4) having an ignition member (36) configured to ignite vapour delivered from the evaporation accelerator (10). The electronically controlled burner (2) comprises at least one fuel pump (8) configured to pump fluid fuel from at least one fuel tank (6) to the evaporation accelerator (10), where the electronically controlled burner (2) comprises means (8) for actively emptying the evaporation accelerator (10).
摘要:
The invention provides a liquid fuel burner (110) comprising a burner head (114), a liquid fuel reservoir (116) for containing a liquid fuel, and a pump (118) for pumping the liquid fuel from the reservoir (116) to the burner head (114). The pump (118) includes a cylinder (140), and a piston (142) which is displaceable relative to the cylinder (140) so that liquid fuel is drawn into the cylinder (140) when the piston and cylinder are displaced in a first direction relative to one another, and the liquid fuel is pumped out of the cylinder (140) when the piston and cylinder are displaced in a second, opposite direction relative to one another. The pump (118) also includes an inlet valve (144) for allowing liquid fuel to be drawn into the cylinder (140) from the reservoir (116), an outlet valve (146) for allowing liquid fuel to be pumped out of the cylinder (140) to the burner head (114), and a displaceable mass which due to its weight applies sufficient force to cause displacement of the piston (142) relative to the cylinder (140) in the second direction, thereby to pump liquid fuel out of the cylinder (140) to the burner head (114).
摘要:
A carbon dioxide concentration measuring device or a method of measuring carbon dioxide concentration which can measure the carbon dioxide concentration in outside air with high accuracy is provided. A carbon dioxide sensor mounted in a heating appliance includes a generator which generates electric power through the use of combustion heat, more specifically through directly converting the heat energy of combustion heat from a flame for heating into electrical energy. The carbon dioxide sensor operates through the use of electrical energy generated by the generator, so unlike a carbon dioxide sensor in a related art which operates through the use of a consumable power source such as a dry cell, as long as electrical energy is generated by the generator, the emission intensity of infrared rays does not change with time, or a computing process by a control circuit is not impeded, so an error due to a change in the emission intensity of infrared rays or the impediment to the computing process by the control circuit in the result of measurement of carbon dioxide concentration is impeded.

Disclosed herein is a far infrared heater using biofuel. The far infrared heater includes a fuel combustion unit (110), a far infrared transmission window (120), a thermal power controller (130) and an automatic extinguishing unit (140). The fuel combustion unit burns a biofuel stored therein to generate heat. The far infrared transmission window surrounds the fuel combustion unit to prevent flames generated by burning the biofuel from being exposed to the outside. The far infrared transmission window allows far infrared rays generated from the heat source to be radiated to the outside through the far infrared transmission window. The thermal power controller adjusts the degree to which the opening formed in the fuel combustion unit opens and thus controls the thermal power of the heater. The automatic extinguishing unit automatically closes the opening of the fuel combustion unit when the heater vibrates or tilts thus preventing the biofuel from burning or leaking.
摘要:
A safety device for an oil burner is capable of detecting abnormal combustion which forms an excessively decreased flame, for example, sufficient to produce incomplete combustion gas to operate a fire-extinguishing device (28) of the oil burner. The safety device includes an abnormal combustion sensing and actuation mechanism (52, 56, 54) which is adapted to receive heat rays from the oil burner to detect the abnormal combustion and a starting member (66) selectively actuated by the mechanism to operate the fire-extinguishing device when the mechanism detects the abnormal combustion.
