The utility model means to control the heating power of the steam generator through the circuits and arranges the control switch on a host machine panel, so that the operators can conveniently adjust the heating power of the steam generator so as to regulate the steam amount of the steam output to meet the demands of different places and different objects in the practical using with flexible and convenient operation.

Description

A kind of seat formula steam generating ironing machine with power adjusting

Technical field the utility model relates to a kind of steam electric appliances, particularly a kind of seat formula steam generating ironing machine that is used for ironing clothes.

Background technology seat formula steam generating ironing machine generally comprises main frame, water storage tank, steam generator, steam lead and shower nozzle etc., use principle of electric-heating to make water boiling vaporization produce high-temperature steam, be transported to shower nozzle by conduit,, realize the function of ironing clothes from the spray orifice ejection of shower nozzle.Common product has only a fixing heating power, and the quantity of steam of generation is fixed, and in actual the use, owing to have different use occasions, different use object, has made things convenient for so fixing output quantity of steam uses with regard to underaction.

Summary of the invention purpose of the present invention is to provide a kind of and can regulates heating power easily, thereby regulates the seat formula steam generating ironing machine of the quantity of steam of output steam.

The object of the present invention is achieved like this, it comprises main frame, water storage tank, steam generator, steam lead and shower nozzle etc., it is characterized in that: also comprise a power conditioning circuitry in the current supply circuit of steam generator, this power conditioning circuitry comprises a gauge tap, a pulse shaper, a decade counter circuit, a photoelectricity coupling circuit and a silicon-controlled voltage regulation circuit; Gauge tap is installed on the host panel, its contact pin is connected to the input of pulse shaper, the output of pulse shaper, be connected to the pulse input end of counting circuit, the terminal count output of counting circuit is connected to the luminous end of photoelectricity coupling circuit by resistance, the photosensitive end of photoelectricity coupling circuit, be serially connected in the charge circuit of silicon-controlled voltage regulation circuit, the output of silicon-controlled voltage regulation circuit is serially connected in the current supply circuit of steam generator electrothermal tube.

The utility model is controlled the heating power of steam generator by using electronic circuit, and gauge tap is arranged on the host panel, make operator's heating power of steam regulation generator easily, thereby regulate the quantity of steam of output steam easily, to be fit to different use occasions in actual use the, the different needs that use object, use more flexible.

Description of drawings Fig. 1 is circuit theory diagrams of the present utility model.

The specific embodiment describes present technique below in conjunction with accompanying drawing:

Among Fig. 1, touch-switch S0 is installed on the host panel as power control switching, is convenient to operation.The two ends of S0 are connected to the input of pulse shaper, pulse shaper can be by gate circuit, flip-flop circuit or triode constitute, play the effect that makes work more reliable and more stable, present embodiment adopts to be made up of time base circuit U1 and peripheral cell, the output of pulse shaper is connected to the count pulse input CLK end of the decade counter circuit of being made up of U2, whenever press S0 one time, just to pulse of CLK end input, the Q5 of U2 is connected to reset terminal RST pin, when high level appearred in Q5, the U2 zero clearing that resets came back to the state of Q0 output high level.So when constantly pressing S0, U2 just exports high level at output Q0-Q4 circularly successively.

The output Q0 end of U2 is set to " 0 " i.e. " disconnection ", when Q0 end output high level, circuit disconnects no-output, Q1 is set to " 4 " i.e. " total power ", the straight-through maximum output of circuit, output Q2-Q4 then respectively is serially connected with a dropping resistor, make output obtain certain weakening, the output of Q1-Q4 is connected to the luminous end of photoelectrical coupler U3, the photosensitive end of U3 is connected in the charge circuit of silicon-controlled voltage regulation circuit, the variation of the photosensitive end resistance value of U3 affects the variation of thyristor operating angle, thereby has controlled the variation of output voltage.

When U2 output Q1-Q4 exported high level successively, because the resistance difference that Q1-Q4 connect, the electric current of the U3 luminous end of flowing through was just different, and the resistance value that is reflected to the photosensitive end of U3 is also different, thereby was controlling the different voltage of silicon-controlled voltage regulation circuit output.The output of silicon-controlled voltage regulation circuit, be connected in the current supply circuit of electrothermal tube RL of steam generator in the main frame, the variation of its output voltage, cause the variation of steam generator heating power, thereby controlled the vaporization rate of water in the steam generator, also just controlled the size of the quantity of steam of output steam.

U2 output Q0-Q4 is connected with luminous tube LED0-LED4 simultaneously, be installed on the host panel, be convenient to display working condition, when the user presses power control switching S0, Q0-Q4 exports high level successively, and luminous tube LED0-LED4 shows that also successively by only luminous operating power changes by " 0-4-3-2-1 ", select suitable operating power and produce suitable steam output quantity for the user, reach the design's purpose.

The required 12V dc source of control circuit passes through transformer T transformation by the 220V power supply, and rectifying and wave-filtering is obtained then.Current supply circuit at steam generator electrothermal tube RL also is serially connected with temperature controller K0 and thermal fuse F, temperature controller and thermal cut-off are installed on the outer wall of steam generator, play the effect of control temperature and insurance, its operation principle is the same with the common steam pressing machines, does not need here to illustrate again.

The design also has lack of water outage and warning function, form by water level switch KS and BG1, BG2 etc., water level switch generally uses as boiler, atomizing humidifier etc. in household electrical appliance, is cooperated by magnetic float and dry-reed tube switch to constitute, and is installed in the water storage cup.When water level just often, water level switch KS disconnects, BG1, BG2 end, steam generator is working properly; When decline of water table during to low water level, water level switch KS connects, the BG1 conducting, and buzzer sends chimes of doom; remind the user to note adding water, also conducting of BG2 simultaneously, the voltage of shutoff U3 luminous end; controllable silicon is ended, and the steam generator outage quits work, and plays the effect of protection machine.
