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 utility model is 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 is also 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 one end of current-limiting resistance respectively with air-out motor side, the other end of described current-limiting resistance connects from the different input pins respectively at single-chip microcomputer, the output pin of described single-chip microcomputer 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 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 one end of current-limiting resistance respectively, and the output pin of described circuit amplifying 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 which.
Described current amplification circuit adopts Darlington transistor or transistor amplifier.
In the present embodiment, current-limiting resistance adopts fixed carbon resister, 1W/65K, and, conventionally select the above resistance of 1W;
Single-chip microcomputer adopts can revise formula single-chip microcomputer; Current amplification circuit adopts transistor amplifier or Darlington transistor amplifying circuit, and single-chip microcomputer is because of the very little directly control relay of electric current, the folding that the output current of transistor amplifier more greatly can control relay; The input pin of transistor amplifier first passed to high level signal by single-chip microcomputer, and the output pin of transistor amplifier is passed to relay by low level signal again and carried out folding, thus control load.
