Abstract
The photoconduction of household electrical appliance leads to a control device, comprises single-chip microcomputer, Switching Power Supply and pilot lamp, and described single-chip microcomputer is connected with Switching Power Supply and pilot lamp; Also comprise a phototriode and an electric capacity and resistor coupled in parallel circuit; The emitter of described phototriode connects power supply; Collector and electric capacity and resistor coupled in parallel circuit and single-chip microcomputer are connected, electric capacity and resistor coupled in parallel circuit ground.Owing to adopting such structure, when there being illumination, phototriode conducting, single-chip microcomputer work, pilot lamp is luminous, and now can operate the switch etc. of control, electrical equipment is started working.
Description
Technical field
The photoconduction that the utility model relates to a kind of household electrical appliance leads to control device.
Background technology
Currently available technology, a kind of control device of upper ability of swimming electric kettle, comprise single-chip microcomputer, Switching Power Supply and pilot lamp, described single-chip microcomputer is connected with Switching Power Supply and pilot lamp.Existing problems are: as long as Switching Power Supply electrically connects with city, even if do not work, pilot lamp also can be luminous shinny; One is waste electric energy, and two shorten serviceable life.
Utility model content
The purpose of this utility model is: provide a kind of photoconduction of household electrical appliance to lead to control device, and it has not pulling out under power conditions, and when night is unglazed, pilot lamp extinguishes, and has saved electric energy, has increased the service life.
The utility model is achieved in that a kind of photoconduction of household electrical appliance leads to control device, comprises single-chip microcomputer, Switching Power Supply and pilot lamp, and described single-chip microcomputer is connected with Switching Power Supply and pilot lamp; Its special character is: also comprise a phototriode and an electric capacity and resistor coupled in parallel circuit;
The emitter of described phototriode connects power supply; Collector and electric capacity and resistor coupled in parallel circuit and single-chip microcomputer are connected, electric capacity and resistor coupled in parallel circuit ground.
The photoconduction of a kind of household electrical appliance of the utility model leads to control device, and owing to adopting such structure, when there being illumination, phototriode conducting, single-chip microcomputer work, pilot lamp is luminous, and now can operate the switch etc. of control, electrical equipment is started working.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of photoconduction of household electrical appliance leads to control device, comprises single-chip microcomputer, Switching Power Supply and pilot lamp, and described single-chip microcomputer is connected with Switching Power Supply and pilot lamp; Also comprise an a phototriode Q1 and electric capacity C and resistance R parallel circuit;
The emitter of described phototriode Q1 connects power supply; Collector and electric capacity C and resistance R parallel circuit and single-chip microcomputer are connected, electric capacity C and resistance R parallel circuit ground connection.
When there being illumination, phototriode Q1 conducting, the voltage signal of the collector of phototriode Q1 and electric capacity C and resistance R parallel circuit is delivered to single-chip microcomputer, then pilot lamp is luminous.
The utility model can be used for its household electrical appliance of base such as electromagnetic oven, upper ability of swimming electric kettle.
Above-described is only preferred embodiments of the present utility model.It should be pointed out that for the person of ordinary skill of the art, when not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
