Abstract
The utility model discloses an intelligent range hood provided with a control device. The utility model employs two heat-variable resistors of negative temperature as transducers, and the difference in temperature of the transducers enables the junction to produce electric potential which sparks the conduction of controlled silicon by being enlarged and shaped via an integrated circuit thereby achieving the auto control of the range hood. The device is simple in structure, low in cost, convenient in usage and excellent in effects, the utility model also can achieve the aim of controlling the range hood immediately.
Description
The utility model relates to a kind of improvement of smoke exhaust, and it is to belong to the household electrical appliance class.
At present, more and more smoke exhaust is used in Duo family or restaurant, their mist extractor function is fairly perfect, but its automatic monitoring function is then poor, for this reason, there are many relevant technologies improvement projects to be suggested, for example Chinese patent CN2291603Y number a kind of about mentioning in " Computerized intelligent type range hood " by housing, the body that blower fan and keyboard are formed, its housing is provided with a controller, and this controller is by power circuit, testing circuit, news are rung circuit, display driver circuit, controlable electric current and microcomputer chip connect to form through lead, and power circuit exports testing circuit respectively to, news are rung circuit, display driver circuit and microcomputer chip, and microcomputer chip is respectively through the lead connection detection circuit, news are rung circuit, display driver circuit, controlable electric current and keyboard, its dependable performance has multiple prompt facility.But its complex structure, the manufacturing cost height.
Task of the present utility model is that a kind of intelligent smoke exhaust will be provided, and it is simple in structure, and production cost is low, and is easy to use, effective, can accomplish to control immediately the work of smoke exhaust.
Task of the present utility model is to finish in such a way, increase a control device in this intelligent smoke exhaust, this control device is to adopt the thermistor of two negative temperature effects as sensor, utilize the temperature of gas burner burning smoke thermal current generating and indoor temperature difference as driving signal, by integrated circuit amplification, shaping, trigger the semiconductor controllable silicon at last and produce action, reach the purpose that automatic control smoke exhaust carries out work.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an intelligent smoke exhaust control device circuit diagram of the present utility model.
As we know from the figure, two negative temperature thermistors 1 and 2 use as sensor, thermistor 1 be contained in smoke exhaust under, and thermistor 2 is installed in smoke exhaust edge corner, its ambient temperature relatively approaches room temperature, when gas burner burns, thermal current makes and forms a temperature difference between the thermistor 2 under thermistor 1 and the room temperature, the current potential at contact A place changes like this, contact A is the input of integrated circuit 3, and after this signal amplified through integrated circuit 3, the integrated circuit 4 of base when entering " 555 " carried out shaping, export effective pulse signal then, and the output 5 of integrated circuit 4 connects the control utmost point of controllable silicon 6, triggers controllable silicon 6 conductings, makes smoke exhaust 7 and power connection, smoke exhaust enters duty automatically, and controllable silicon 6 is power switches of smoke exhaust 7.And the temperature difference of being gathered when thermistor 1 and 2 disappears, and the current potential of A contact is zero, and no signal produces, controllable silicon 6 not conductings, and the power supply of smoke exhaust 7 is cut off, and it automatically quits work, thereby reaches the work that realizes the control smoke exhaust.
Claims (1)
