Description

Garment steamer

Technical field

The utility model relates to the pressing machines technical field, is meant a kind of steam extension pressing machines especially.

Background technology:

Traditional garment steamer generally adopts mechanical switch control, and power is invariable during its ironing clothes, because the clothing material is various, wishes during ironing clothes to use different quantity of steams according to material.Use the Garment Steamer Machine of common firm power can't reach this purpose.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of garment steamer of power variable is provided.

For achieving the above object; the technical scheme that the utility model provides is: a kind of garment steamer; include power switch OA; it is characterized in that: power switch QA links to each other with power supply; the end of power switch QA links to each other with protection temperature controller WK1; the protection temperature controller WK1 other end links to each other with heater element RH, and the heater element RH other end links to each other with temperature control temperature controller WK2, at the two ends of heater element parallel resistance R4, indicator lamp LED.The temperature control temperature controller WK2 other end links to each other with the A2 end of bidirectional triode thyristor BT, and the A1 end of bidirectional triode thyristor BT links to each other with the protection inductance L, and the protection inductance L other end links to each other with power switch QA; Connect a two-way triggering transistor DB at the control utmost point G of controllable silicon BT, two-way triggering transistor DB links to each other with capacitor C 2, resistance R 2, resistance R 2 and potentiometer RL polyphone, and the end of potentiometer RL links to each other with the A2 of controllable silicon BT end, a potentiometer RL resistance R 3 in parallel; The other end of capacitor C 2 links to each other with the A1 end of controllable silicon BT.In A1, the A2 of controllable silicon BT end parallel resistance R1, capacitor C 1.

The utility model is to install a control circuit on the basis of common Garment Steamer Machine additional, this circuit is controlled heater element two ends input voltage by adjusting the silicon controlled angle of flow, thereby make the power output of heater element to change as required, and can limit the minimum output power of heater element.

Description of drawings:

Fig. 1 is the utility model electricity theory structure schematic diagram.

The specific embodiment:

Referring to shown in Figure 1; the power switch QA of present embodiment links to each other with power supply; the end of power switch QA links to each other with protection temperature controller WK1; the protection temperature controller WK1 other end links to each other with heater element RH; the heater element RH other end links to each other with temperature control temperature controller WK2, at the two ends of heater element parallel resistance R4, indicator lamp LED.The temperature control temperature controller WK2 other end links to each other with the A2 end of bidirectional triode thyristor BT, and the A1 end of bidirectional triode thyristor BT links to each other with the protection inductance L, and the protection inductance L other end links to each other with power switch QA.Connect a two-way triggering transistor DB at the control utmost point G of controllable silicon BT, two-way triggering transistor DB links to each other with capacitor C 2, resistance R 2, resistance R 2 and potentiometer RL polyphone, and the end of potentiometer RL links to each other with the A2 of controllable silicon BT end, a potentiometer RL resistance R 3 in parallel; The other end of capacitor C 2 links to each other with the A1 end of controllable silicon BT.In A1, the A2 of controllable silicon BT end parallel resistance R1, capacitor C 1.

Operation principle of the present utility model is: connect power switch QA, to the C2 charging, the last voltage of C2 is charged to when being about about 33V circuit by heater element RH, RL (R2, R3)., two-way triggering transistor DB conducting, also conducting of bidirectional triode thyristor BT, after the controllable silicon conducting, heater element has electric current to flow through, power output, along with the DB conducting, the last voltage of C2 is bled off fully, and DB ends again, controllable silicon ends when electric current is kept electric current less than it, begins next circulation then.Adjust the resistance value of potentiometer RL, adjustable capacitance C2 discharges and recharges the time, and the time that discharges and recharges is short more, and the heater element power output is big more.Resistance R 3 defines capacitor C 2 maximums and discharges and recharges the time, like this, sets the resistance of R3, just can change the minimum output power of heater element RH.R1, C1 and inductance L are used to protect controllable silicon BT.Protection temperature controller WK1, temperature control temperature controller WK2 provide safeguard protection for circuit.
