Detailed description of the invention
This utility model safe electric blanket temperature control switch is achieved in that and illustrates below in conjunction with accompanying drawing.See Fig. 1, safe electric blanket temperature control switch, it is by shell 1, power supply indicator 2, high/low temperature selects switch 3, quick heat time heating time display lamp 4, thermoregulation knob 5, quick heat time heating time sets button 6, heating wire break alarm display lamp 7, burner on light 8, on and off switch 9, control circuit plate 10, electric blanket accesses jack 11 and attaching plug 12 forms, power supply indicator 2, high/low temperature selects switch 3, quick heat time heating time display lamp 4, thermoregulation knob 5, quick heat time heating time sets button 6, heating wire break alarm display lamp 7, burner on light 8 and on and off switch 9 are arranged on the panel of shell 1, and be connected with control circuit plate 10 respectively, control circuit plate 10 is fixed in housing 1, electric blanket accesses jack 11 and is arranged on the side of shell 1, during use, the attaching plug 12 of temperature control switch is inserted mains supply, electric blanket plug inserts in temperature detect switch (TDS) jack 11.
See Fig. 2, be safe electric blanket temperature control switch schematic block circuit diagram
It is provided with in control circuit plate 10: rectification and waveform shaping circuit, heating pulse dutyfactor adjustment circuit, quickly heating timing shutdown timing circuit, anti-heating wire broken string firing circuit and thyristor output circuit, rectification and waveform shaping circuit are connected with heating pulse dutyfactor adjustment circuit；Heating pulse dutyfactor adjustment circuit, quickly heating timing shutdown timing circuit and anti-heating wire broken string firing circuit perform circuit with heating respectively and are connected, heating performs circuit and is connected with thyristor output circuit, thyristor output circuit is connected with electric blanket, accesses power supply by rectification and waveform shaping circuit.
Power supply of the present utility model is rectified and waveform shaping circuit divides into the continuous impulse signal of 6.25Hz, enters heating pulse dutyfactor adjustment circuit.Heating pulse dutyfactor adjustment circuit utilizes 10 division function of integrated circuit, selects the different pulse spacings, just can export ratio is different within the unit interval pulsewidth and pulse spacing signal.This signal enters heating and performs circuit, controls the high level square wave that output width is different, to trigger thyristor output circuit conducting, makes electric blanket heating power.
Quickly heating timing and shutdown timing circuit are made up of 2 intervalometers, one intervalometer is for quickly heating, export high level when can be set in 20,40,60 or 80 minutes and perform in circuit to heating, make heating perform circuit and export continuous high level, triggering controllable silicon is constantly on, makes electric blanket rapidly pre-warming.The effect of another intervalometer is the longest working time controlling temperature detect switch (TDS), and this utility model design timing is 11 hours 39 minutes.Namely when temperature controller is opened, intervalometer counts simultaneously, arrive 39 points of output low levels when 11, block heating performs the gating circuit in circuit, heating is made to perform circuit output low spot position, thyristor output circuit ends, and electric blanket power supply is closed, the disaster hidden-trouble caused to avoid electric blanket to be energized for a long time or to forget to close electric blanket.
Anti-heating wire broken string firing circuit is the protective measure designed because of the heating wire broken string easy initiation fire of sparking for electric blanket.It is the voltage signal utilizing and detecting heating wire simultaneously and current signal judges whether broken string sparking occur, once occur, export electronegative potential immediately, close heating and perform the gating circuit in circuit, heating is made to perform circuit output low spot position, close thyristor output circuit, open alarm lamp flashing light alarm simultaneously.
This utility model adopts 220V civil power, rectified and waveform shaping circuit, generates positive and negative two half-wave Voltage pulsating direct-current supplies, select switch through high and low temperature, or select a half-wave Voltage pulsating direct-current supply, or both select, delivering in electric blanket, the heating to realize high and low temperature selects.Rectification and waveform shaping circuit also produce the DC source of a 12V, power for complete machine, produce again a power down preventing power supply VCC that can keep about 11.3V for a long time, specialize in quickly heating timing shutdown timing circuit and use.After power down, when not stirring on and off switch, this power supply can keep tens minutes, makes quickly heating timing shutdown timing circuit work on, plays the purpose of power down protection.Meanwhile rectification and waveform shaping circuit, also by city's electric pulse, arrange the 6.25Hz clock signal of the standard that divides into, delivers to heating pulse dutyfactor adjustment circuit and quickly heats in timing shutdown timing circuit.
This utility model safe electric blanket temperature control switch, it is provided with quick heat button, may be set to 80 minutes, 60 minutes, 40 minutes, 20 minutes, the demand under various condition can be met, there is fast heating function, clearly actual heating instruction and electric blanket fault alarm function, meet hommization needs, i.e. timing quickly heating and many grades of fine tuning temperature, can also regularly closing power supply, can meet the crowd demand at various domestic environment temperature, life-time service is neither got angry and safe and reliable.
