Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the control circuit of ceiling type warmer.
Detailed description of the invention
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 first wind and warms up end 2, second wind warms up end 3 and air-out motor side 4, described external mains terminal also warms up relay trigger switch respectively by the first wind warms up electrothermal piece with the first wind and is connected, the trigger switch that second wind warms up relay warms up electrothermal piece with the second wind and is connected, the trigger switch of air-out relay with go out wind turbine and be connected, the warm end of described first wind, second wind warms up end and is connected with one end of current-limiting resistance respectively with air-out motor side, the other end of described current-limiting resistance is connected with one 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 first wind respectively, second wind warms up relay and is connected with the low voltage control end of air-out relay.
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, and the output of described mu balanced circuit is the Vcc end of single-chip microcomputer.
Further, described load switch line also comprises ventilation end 5 or illumination end 6, and the trigger switch of described external mains terminal also respectively by 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 current amplification circuit is connected with the low voltage control end of ventilation relay, illumination relay respectively.Certainly, if warmer is integrated with other function, also can be formed according to which and expand side by side.
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, usually select more than 1W resistance;
Single-chip microcomputer adopts can revise formula single-chip microcomputer; Current amplification circuit adopts transistor amplifier or Darlington transistor amplifying circuit, and wherein Darlington transistor adopts ULN2003, single-chip microcomputer because of electric current is very little cannot direct control relay, the electric current of ULN2003 output more greatly can the folding of control relay; High level signal is first passed to the input pin of ULN2003 by single-chip microcomputer, and low level signal is passed to relay and carried out folding by the output pin of ULN2003 again, thus control load.
Relay can adopt 10A-16A relay open in usual.
In the present embodiment, load switch line contacts with ACL, and optocoupler internal illumination device emits beam, after light-receiving device accepts light, electric current flows out from output, and produces low level signal, after single-chip microcomputer receives low level signal, open this load-relay and export, open load; Otherwise closedown load.
Utilize the powerful load of Single-chip Controlling, the time delay after heating can also be realized, extend the service life of machine; Tradition electrical equipment is without delay function.
The circuit of the present embodiment i.e. safety but cost low, more much lower than specialized controller cost.
Because load is all work under the control of single-chip microcomputer, the function of relevant hommization can be set in advance, this is that regular tap cannot realize, such as: tradition opens heating function, first to open blowing, then open heating, be only safe like this, if first opened heating then to open blowing or forget unlatching blowing, heater high-temperature will be caused to be out of shape or to burn on fire; As long as but this circuit connects heater wire, just can realize blowing by single-chip microcomputer and open with heating simultaneously, avoid disaster hidden-trouble, achieve the object of hommization, so no matter old man or child can courageously use.
