Abstract
An infrared object detector for kitchen range characterized by that, a far infrared transmission diode and a far infrared reception diode are fixed on the base plate, a convex lens is arranged above the diode, a pyroceram is arrange above the convex lens, a diode is connected with a control circuit. The invention can be used to detect whether there is kitchenware on the kitchen range, send the control signal and realize the automatic control for the kitchen range air supply switch.
Description
Technical field
The present invention relates to pyroscan.
Background technology
Along with improving constantly of people's living standard, intelligentized family expenses kitchen range will have the bigger market demand.Kitchen range in use have cooker to be put automatic igniting, cooker to take the function of self-extinguishing away is the intelligentized important contents of kitchen range, and whether this just need install existence that an object detector surveys cooker on kitchen range.Existing magnetic, light, ripple type objects sensor all can not be suitable for using near flame basically.
Summary of the invention
The invention provides a kind of being suitable near the kitchen range infrared ray object detector that uses the flame is arranged.The objective of the invention is to realize by technical scheme shown in the drawings, it has a pedestal 1, on pedestal, fix a far infrared emitting diode 4 and a far infrared reception diode 5, far infrared emitting diode and far infrared reception diode are provided with convex lens 2, and a pyroceram 3 is set above convex lens.
The present invention has fluctuation and corpuscular property, and fluctuation can be measured and have or not cooker on the kitchen range, and is irrelevant with the color and the material of cooker; Corpuscular property can focus on, and is not subjected to the influence of burner shape.The far infrared emitting diode links to each other with a circuit with the far infrared reception diode, and this circuit can carry out modulation and demodulation to the ripple that diode sends, thereby guarantees that detector is not subjected to the interference of ambient light and ripple.The present invention can be arranged on the preformed hole at cooker burner middle part, and interior cooker reflects light wave when on the kitchen range cooker being arranged, and is received diode and receives, and produces control signal; Kitchen range are lighted a fire automatically; When cooker when kitchen range are removed, reception diode is not received signal, kitchen range cut out source of the gas automatically.
The present invention does not have misoperation accurately and reliably, for the intellectuality that realizes kitchen range provides an important devices.
Appended drawings is a structural representation of the present invention.
The tool present embodiment
Pedestal is a truncated cone-shaped, 33 millimeters of following round platform diameters, 24 millimeters of last round platform diameters.Far infrared emitting diode model is GL-2, and far infrared reception diode model is 2CU1A.Convex lens are made by lucite, and lens thickness is 6 millimeters, 15 millimeters of focal lengths.
Claims (1)
1, a kind of kitchen range object detector, comprise a pedestal, it is characterized in that on pedestal, fixing a far infrared emitting diode and a far infrared reception diode, far infrared emitting diode and far infrared reception diode are provided with convex lens, and a pyroceram is set above convex lens.
