Beneficial effect of the present invention is mainly manifested in: effectively avoid that switch damages, security better, the switch applicability is good, reduce costs.
The accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the control circuit of ceiling type warmer.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 1, a kind of control circuit of ceiling type warmer, comprise external mains terminal ACL, described external mains terminal is connected 1 with the mains terminal of load switch line, described load switch line also comprises the warm end 2 of the first wind, the warm end 3 of the second wind and air-out motor side 4, described external mains terminal also is connected with the warm electrothermal piece of the first wind by the trigger switch of the warm relay of the first wind respectively, the trigger switch of the warm relay of the second wind is connected with the warm electrothermal piece of the second wind, the trigger switch of air-out relay with go out wind turbine and be connected, the warm end of described the first wind, the warm end of the second wind is connected with an end of current-limiting resistance respectively with the air-out motor side, the other end of described current-limiting resistance is connected with an end of photoelectrical coupler, the other end of described photoelectrical coupler connects respectively at the different input pins of single-chip microcomputer, the output pin of described single-chip microcomputer is connected with the input pin of current amplification circuit respectively, the output pin of described current amplification circuit warms up relay with described the first wind respectively, the low voltage control end of the warm relay of the second wind and air-out relay is connected.
Further, described external mains terminal ACL is connected with the high-pressure side of step-down transformer T1, the low-pressure side of described step-down transformer T1 is connected with bridge rectifier, and described bridge rectifier is connected with mu balanced circuit, the Vcc end that the output of described mu balanced circuit is single-chip microcomputer.
Further, described load switch line also comprises ventilation end 5 or illumination end 6, and the trigger switch that described external mains terminal is also passed through respectively the ventilation relay is connected with scavenger fan, the trigger switch of illumination relay is connected with lighting,
Described ventilation end, illumination end are connected with an end of current-limiting resistance respectively, and the output pin of described current amplification circuit is connected with the low voltage control end of ventilation relay, illumination relay respectively.Certainly, if warmer integrated other function, also can form expansion arranged side by side according to this mode and get final product.
Described current amplification circuit adopts Darlington transistor or transistor amplifier.
In the present embodiment, photoelectrical coupler adopts 817, and current-limiting resistance adopts fixed carbon resister, 1W/65K, and, usually select the above resistance of 1W;
Single-chip microcomputer adopts can revise the formula single-chip microcomputer; Current amplification circuit adopts transistor amplifier or Darlington transistor amplifying circuit, and wherein Darlington transistor adopts ULN2003, and single-chip microcomputer is because of the very little directly control relay of electric current, the folding that the electric current that ULN2003 exports more greatly can control relay; The input pin of ULN2003 first passed to high level signal by single-chip microcomputer, and the output pin of ULN2003 is passed to relay by low level signal again and carried out folding, thus control load.
Relay can adopt 10A-16A relay open in usual.
