Food processors are equipped with the commutator motor. We discuss the shortcomings and technical advantages of the solutions; look in the instrument, the possibility of how to perform a repair. Food processors are not designed to solve modest goals. Prepare salad - a full bucket, chop vegetables - kgs. We see the lack of a food processor and advantage. Cooking times for two of velikovat unit; It needs to feed a crowd of guests - bingo! Prepare immediately wash the product will remain within the mountain ingredients. Repair of kitchen machines with their own hands is not difficult, managed to dismantle a gimmick. Since each manufacturer tries to perform an original design, will try to do, so no one could get inside the unit. The Soviet technique compares favorably with the food processor, then, as you know, fools in KB did not work ...
Apparatus typical food processor
Repair of kitchen machines with their own hands requires knowledge bases. Inside a snap. site cliche again pertinent. Food Processor is designed to accomplish that today can hand blender with the prefix of the cup with a knife. The functions include the preparation of cocktails. Translated into Russian means: there are three instruments which intersect one another, only the latter will replace all:
- hand blender;
- Table blender;
- food processor.
Critically evaluate the ability of a food processor. Two drives:
- Blender line.
- For grinding and gear through a belt, gear transmission.
KitchenAid Food Processor can not be distinguished from the blender by removing the nozzle, we do not consider the simplest versions of today. Thus, the two drives, each rod for their own purposes. Under the blender is made straight, not at all surprising. Nozzle often milled ingredients are significant loads through the belt can not be conveyed. The really interesting second drive food processor, which accounted nozzle shredders, graters. It is worth the closure sleeve, pressing breaking rotation. Say in advance: in the electric circuit a whole bunch of pressure switch, chop off the power to the device, if not installed protective caps. Of course, protection can be fooled.
Happy easy circuit design. On the electronic card inlet is so familiar RC-filter chain, where one wire supplying the motor, a second input current passes triac control circuit.
Speed control is performed. Describe the action of the circuit:
- Power is supplied to the triac operating in linear mode. A key element is equipped with a decent-sized radiator, dispersing excess heat.
- Come to the control electrode voltage divided by a variable resistor, the reverse motor response - stray EMF when switching sections collector rotating shaft.
- Rotating speed controller, variable resistor changes the voltage value of the control electrode of the triac. Turnovers grow or decrease.
- Increases the load on the engine, the rotor slows down the speed. Falls back EMF value of the parasitic collector voltage of the control electrode of the triac varies, current consumption begins to increase. Following turnover rises again, the engine enters the preset mode.
Simple scheme of self-regulation, from an electrical point of view, no claims to Philips. Well done. Apart from the fifth conductor coming from the engine coming on board, left hanging in the air. However, the fines compared with the Torx screws, screwed into the plastic - a fake. Dvoechka minus: the buyer to inflate mauvais ton. Scheme lacks fuses, thermal protection in excess. In winding fairly written inside hides fuse threshold 135 degrees Celsius. Near another, reusable. It strikes one thing: the power comes from the board comes motor circuit section rotor-stator is held on the board. Why it is hard to say.
The device is considered, just as ABC. Therefore, to repair a food processor easily. Let's see the procedure.
The procedure for inspection of a food processor
Discuss how to fix the food processor. Most readers know the sequence. We explain the issue in detail. Lucky, who was able to make out the food processor, you must do the following:
- Checked the integrity of the cord. Just do the power supply comes on board electrical connector, measure the voltage.
- If the normal 230 volt, phoning input filter capacitor. Successful outcome moves straight to the thyristor, differential input and output voltages of 230 volts.
- On the way to bypass the security switch, remember: switches blocking voltage supply, if no cups. With the power off closable desired circuit until the voltage of the thyristor.
- The control circuit is formed by a rheostat. At one end of the phase element, the other - the land. With the controlled contact of the control potential is removed. Do the following: measuring the voltage between the ends, and then make sure that the control signal Sh is successful. Take care to avoid an electric shock.
- Realized operation ensures that the device is properly in terms of electricians. For a complete happiness measure the rms value of the motor control voltage, at the same time tightening the rheostat handle. The amplitude changes.
- If everything takes place as described for the engine failure. We examine the thermistors, prozvanivatsya winding. The engine is allowed to run on 230 volts directly view performance. The speed will be maximum.
- Separately Call winding collector scroll shaft by hand.
Such inspection procedure. Break resistor (crumble) some rates may not work, change of speed occurs in spurts, is unstable. food processor device provides for the protective relay (DIP), walk through the food chain. From a mechanical point of view, if not rotating belt shaft to check the following:
- Does the belt slips.
- Serviceability of the clutch.
Belt reminds the car. Uneasy gum product with the cut teeth on the gear size. It becomes evident two things:
- the product will work for a long time;
- if the rubber wears off, rassohnetsya, will be extremely difficult to replace.
We recommend tough, hard vegetables to chop. Keep the operating shaft which is not wound. With regard to the drive of the blender, knife does not turn off, it rotates in a food processor. At a time when the corresponding nozzle is not used, the rotating shaft is covered by a protective cover. Without this, the device will not turn on, will be incorrectly switched the relay mentioned above. Harmful use a grater. Tellingly, the tightness of the belt adjustment mechanism is not. Could leave spring-loaded with a mobile cog, the position would be regulated by a screw, even Torx. would cause the rubber components last longer.
What can go wrong in a food processor, we describe themselves feel threatened only triac and a capacitor at the input. Brush commutator motor protected varistors, spark quenching with a strong increase of the voltage, do not allow the motor to burn out if overawed by unknown reason, filter the input. Beginners surprise pills blue soldered to the body, in fact spark closes two varistors, is extinguished if the voltage amplitude will allow. Given the clumsy thermal protection, discussed above, the impression: the designers err on all occasions. Philips food processor will work... if the repair will survive!
Some units have an integral body. To the service center noticed the opening try an unknown self-taught master.
The device is based on speed control, change the amplitude easier. If asynchronous motors respond to inverter control, in this case, repair Food Processors Moulinex associated with collectors, and only with them. The species can be controlled by microchips. Is done by changing the duty cycle varies the current value leads to a change in engine speed. Hopefully, now the repair of a food processor Mriya readers on the teeth and on the shoulder. Please note: the thickness of the wire coils, the engine pulls better. To feel, hand blenders vote thickness winding.
