Technology And Development At Vacuum Cleaner

The basic principle is today when almost all vacuum cleaners immediately, even if it is the ground of Bissell sweepers still there to buy. An engine of the type-series final, Allstrom or Spaltpolmotor. This Ansaugenergie must pass through a filter, the engine before the dust preserved. Here is the real problem with the vacuum cleaner: The required suction at the end of, for example, 1.5 m long vacuum pipe, the filter effect before the engine just as opposite as the desire, the dust, or parts thereof not elsewhere in the device back into the environment blow. The air must be – no dust and dirt – the device is constantly happening. If the air does not leave the enclosure, it would immediately inside an over-pressure, either the engine can overheat or the case is beyond or apart expresses. The vulnerabilities would be seals and closures.
This issue is also reflected in the different development paths of the manufacturer. However, distinguished himself quickly, that the comfort of the device for cleaning large wrote. The answer was the vacuum cleaner bag. Vacuum cleaners with dust bags, however, are characterized by a decisive disadvantage: Not only that – as described – the suction comparatively lower than in vacuum cleaners without bag. The suction power is also reduced permanently, because dust and dirt to clog the engine Ansaugweg. If the bag more than half full, the suction markedly lower.
To address the problem under control, developed James Dyson, a British engineer, in the mid-1980s, a vacuum cleaner after the cyclone principle. This technique, similar to the Fliehkraftabscheider, is the centrifugal force was exploited in order to prevent the re-run to the outside air or dust particles. The air is in one or more cylinders in centrifugal motion, the particles are on the inside of the cylinder from. Dyson vacuum cleaners have more than one cylinder. The success of the principle led to now that other manufacturers put on beutellose technology. It is usually only one cylinder is used.
Suction

Reinhartshausen physico suction is described by three figures: the flow rate, the speed of the air and the maximum pressure differential. The suction is done solely by the pressure difference characterized, however, this only means an interruption of the suction determined. This is comparable to the typical test, with the suction of the vacuum cleaner, and – for lack of display – the degree of filling of the bag is measured by placing the hand on the open end of the intake pipe and then alternately aufpresst decreases. The suction can be perceived only a very uncertain conclusion as to whether sufficient gesaugt when the suction tube diagonally on the carpet is attached. The flow rate and speed of sucking air complement the correct description of the suction.
However, there are hardly any manufacturers of these values. Instead, the customer with the wattage, suggests an effective suction. The electrical power may, however, in many respects inadequate to describe the suction. First of all, there is the engine with all its attachments. Depending on the model here is more or less power wasted. In addition, Watts claims in vacuum cleaners with bags which are not in accordance with the principle Dyson to compare.
This is proven by taking a look at the story. A simple vacuum cleaner of the 70s was, for example, the Hitachi CV 145, a round dwarf, in the absence of vacuum cleaner bags auskam and many students in his Gnadenhof Buden was and still will. Although it takes much less watts than the vacuum cleaner with bag, he shines with amazing Saugverhalten. However, its filter value for today’s disastrous situation.
HEPA filter

The term HEPA stands for High Efficiency Particulate Airfilter. It is Schwebstofffilter, according to DIN 1946 are standardized. They are capable of a dust particle size from 0.1 to 0.3 microns to approximately 100 percent filter. Thus they are protected against viruses and bacteria, mites and eggs Milbenexkremente, asbestos, aerosols, respirable dust and some toxic species, pollen and smoke particles. Vacuum cleaners with HEPA filters are recommended for allergy sufferers. Other Filtersystem different manufacturers is now approaching a similar filter values, although some of the devices clearly are cheaper.
