Abstract
The utility model relates to an induction electrical fan, which consists of a control device and a fan motor; the control device is composed of a single chip and an infrared sensor; an infrared sensor is mounted on the front surface of the electrical fan; an output end of the infrared sensor is connected to an input end of the single chip; one output end of the single chip controls the fan motor through a first relay, and the other output end of the single chip controls the fan motor through a second relay; the induction electrical fan is characterized in that the output end of the infrared sensor is connected to the input end of the single chip and the single chip controls the fan motor through the relay. When the infrared sensor detects the presence of the people, the electrical fan works normally; when the infrared sensor detects the absence of the people, the single chip will start timing, and when no person is detected in the predefined time, the single chip controls the electrical fan to run at a low speed through the second relay; and when the people is still not detected in the predefined time, the single chip cuts off power supply and the electrical fan stops rotation.
Description
Technical field
The described inductive electric fan of the utility model relates to daily necessities, specifically a kind of electric fan.
Background technique
Electric fan becomes one of the instrument of enjoying the cool that people use always because price is low, easy to use at present.The development of Along with computer technology, single-chip microcomputer in the extensive use electric fan control circuit, make it intelligent more.But its deficiency is: when the people who enjoys the cool left fan, fan still ceaselessly rotating with original state, had both wasted the energy, had reduced the working life of electric fan again.To existing problem in the above-mentioned existing technology, a kind of novel inductive electric fan of research and design, existing problem is very necessary in the existing technology thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned existing technology; The purpose of the utility model is a kind of novel inductive electric fan of research and design; Thereby solve when the people who enjoys the cool leaves fan; Fan still ceaselessly rotating with original state, had both wasted the energy, had reduced the problems such as working life of electric fan again.The described inductive electric fan of the utility model is made up of control gear and fan electromotor; Described control gear is made up of single-chip microcomputer and infrared senor; Infrared senor of positive installation above electric fan; The output terminal of infrared senor is connected to an input end of single-chip microcomputer, and an output terminal of single-chip microcomputer is through relay one control fan electromotor; Another output terminal of single-chip microcomputer is through relay two control fan electromotors.
The technological scheme of the described inductive electric fan of the utility model is: an infrared senor is set, the output terminal of infrared senor is connected to the input end of single-chip microcomputer, single-chip microcomputer is through relay control fan electromotor.When electric fan was worked, if infrared senor has detected man-hour, electric fan will be by the prior pattern proper functioning of setting of people; If when infrared senor detects nobody, single-chip microcomputer will pick up counting, at preset time t
1Interior (for example 5 minutes) when detecting nobody, single-chip microcomputer will transfer low-speed running (for example sleep state) to through another relay two control electric fans; At preset time t
2Man-hour has not still been detected in interior (for example 15 minutes), the power supply of single-chip microcomputer block system relay, and electric fan will stop operating.
The beneficial effect of the described inductive electric fan of the utility model is, the short time nobody the time, the electric fan low-speed running; For a long time nobody the time; Electric fan shuts down automatically, reaches energy saving, prolongs purpose such as electric fan working life.Only needing to increase an infrared senor, whether just can according to survey have people automatically control electric fan, very convenient if changing SCM program.
Description of drawings
The utility model has a width of cloth accompanying drawing,
Fig. 1 is an inductive electric fan structured flowchart schematic representation.
Among the figure: 1, infrared senor 2, single-chip microcomputer 3, relay 1, relay 25, fan electromotor.
Embodiment
For example shown in the accompanying drawing, described inductive electric fan is made up of control gear and 5 of fan electromotors in the practical implementation of the utility model; Described control gear is made up of single-chip microcomputer 2 and 1 of infrared senor; Infrared senor 1 of positive installation above electric fan; The output terminal of infrared senor 1 is connected to the input end of single-chip microcomputer 2, and an output terminal of single-chip microcomputer 2 is through relay one 3 control fan electromotors 5; Another output terminal of single-chip microcomputer 2 is through relay 24 control fan electromotors 5.
