Abstract
The utility model discloses a motor electronic braking device for a washer and a swing dryer, which is composed of an electronic timer, a contactless switch, a multi-contact switch, and a filter. The utility model is directly connected with the circuits of the washer and the swing dryer. The utility model is characterized in that the number of mechanical connection points is few, the braking failure can not be generated easily to avoid burning out the motor, and the braking performance is steady. When the covers of the washer and the swing dryer are opened, the power of the motor is cut off, the power supply enters the braking device simultaneously, the braking device outputs the direct current after filtering, the direct current is added on the two ends of the motor, and the energy consumption braking is carried out to cause the motor to stop rotating.
Description
The utility model relates to a kind of improving technology in the household appliance technical field.Say so the more specifically motor electronic brake apparatus of washing machine, drier is particularly suitable for the motor braking of drier.
The motor braking of the at present domestic washing machine that generally uses, drier generally is made of pull bar backguy, spring, brake contiguous block, brake supporting plate, brake disc by mechanical braking.Exist mechanical connection point many, mechanical wear is arranged, braking ability can not be steady in a long-term, easily produces mechanical breakdown, cause burning out motor, and manufacturing process is many, processed complex, maintenance cost height.
The purpose of this utility model is to install easily in order to simplify the braking control system of washing machine, drier, to realize contactless braking, avoid burning out motor, producing, and braking ability is stable.
The utility model is realized in the following manner: when connecting power supply, open timer, power supply is added in the motor two ends through multicontact switch, and motor is run well.After opening washing machine or drying cover, the part contact of interlock multicontact switch disconnects and the part closing of contact, motor outage this moment.Simultaneously, electric current becomes forward voltage to enter controllable silicon through the dropping resistor step-down after the silicon diode halfwave rectifier again, the silicon controlled control utmost point obtains certain half-wave homophase trigger current by current-limiting resistance, make the controllable silicon conducting, be added on the motor two ends through the filtered direct current of filter capacitor, motor begins dynamic braking, makes the motor stall.Because current-limiting resistance is again the load resistance of triode, offer the triode forward voltage, and the half-wave voltage behind the diode rectification is charged to timing capacitor through another road timing resistor, when the voltage at timing capacitor two ends surpasses the breakdown voltage of Zener diode, the silicon voltage regulator diode conducting, forward bias is provided for the base stage of triode, makes its conducting.The voltage of the colelctor electrode of silicon triode descends rapidly, makes the silicon controlled control utmost point not have normal trigger current, and being added on the controllable silicon anode is pulsating semi-wave voltage, when voltage zero-cross, controllable silicon ends, and the voltage at motor two ends is disconnected, and the braking timing process finishes.After closing washing machine, drying cover, the interlock multicontact switch resets, and motor starts once more.The voltage at the timing capacitor two ends after resetting is bled off, for regularly getting ready next time.
The utlity model has following advantage: its mechanical connection point is few, does not have the machinery wearing and tearing, can not produce the mechanical braking fault, thus can avoid burning out motor, and braking time regulates easily, and braking ability is stable, makes handling ease.
Embodiment of the present utility model: the timer among Fig. 1 (12) is connected on the power supply, and the inlet wire of multicontact switch (3) is connected on the output line of timer.Multicontact switch among Fig. 2 has support (3a) and (3b), in single face contact (3c), (3d), (3f), (3g) and two-sided contact (3e) are arranged, (3c), (3d), (3f) and (3g) are single face contact elastic copper sheets, (3e) is two-sided contact elastic copper sheet, contact (3c) is relative with contact (3g), and contact (3e) is positioned between (3d) and (3f).When opening washing machine, drying cover, the contact of multicontact switch (3c) and (3g), contact (3e) and (3d) disconnect, and contact (3e) and (3f) closure make motor (11) outage.Simultaneously, silicon diode among Fig. 1 (4) also is connected on the output line of timer, the output of silicon diode is in series with dropping resistor (5) current-limiting resistance (6) and timing resistor (7), and dropping resistor (5) is connected with controllable silicon (8) again, current-limiting resistance is connected with silicon triode (9) and controllable silicon respectively again, timing resistor is connected with (3d), timing capacitor (1), silicon voltage regulator diode (10) in the multicontact switch respectively again, the input of filter capacitor (2) is connected with (3f) in the multicontact switch, and output is connected with motor.
Claims (3)
1, a kind of washing machine, drying machine motor deceleration of electrons device is characterized in that having being the multicontact switch of series relationship and one with motor, timer and providing galvanic timing electronic switch for motor by cover control.
2, brake apparatus according to claim 1 is characterized in that said multicontact switch is the combination by single face contact elastic copper sheet (3c), (3d), (3f), (3g) and two-sided contact elastic copper sheet (3e).
