Definitions

  • the present invention relates to a vacuum cleaner with a vacuum cleaner housing which has a dust chamber with a dust bag arranged therein and a motor chamber in communication with the dust chamber with a blower and a motor for driving the blower, the motor being enclosed by a hood attached to the blower is.
  • a vacuum cleaner according to the preamble is known from DE-PS 34 43 837, in which on the outside of the hood enclosing the engine is a circumferential frame surrounding the air outlet openings, into which a filter with an airtight seal can be inserted and replaced.
  • the air drawn in by the engine blower block passes through the air outlet openings of the hood, passes through the filter and enters a space which is essentially delimited by the outer wall of the housing on the one hand and the wall of the hood on the other hand and which it leaves to the outside through the air outlet openings in the outer wall of the housing.
  • the space between the outer wall of the housing and the hood serves to expand the air and thus reduce noise during the operation of the vacuum cleaner.
  • the filter arranged in the area of the air outlet openings of the hood increases the pressure in the hood with increasing contamination of the filter in such a way that there is an undesirably high level of noise in the operation of the vacuum cleaner. Furthermore, due to the way the hood is placed on the engine blower block, the vibrations are disadvantageously transmitted.
  • the present invention has for its object to propose a vacuum cleaner that has a pleasantly reduced noise level in operation while maintaining good suction and filtering performance.
  • a chamber system is arranged outside the hood enclosing the engine, through which the air is guided before it emerges from the housing. At least one of the chambers has webs extending in the direction of flow, so that air channels are formed, as a result of which the air flow is divided.
  • the air outlet openings of the hood enclosing the engine are arranged at a right angle to the air blasting direction of the engine blower block. This has the advantage that the air is forced to change speed at the same time as the direction changes.
  • a cylinder chamber is arranged around the hood enclosing the engine, which forms a space surrounding the hood.
  • the air outlet openings of this cylinder chamber are arranged in close proximity to the air outlet openings of the hood, but there is an airtight partition between the two air outlet openings, so that those from the hood escaping air must flow around the hood through the entire cylinder chamber until it leaves the cylinder chamber.
  • an outer delimiting wall of the cylinder chamber is arranged substantially flat and at a short distance from the air outlet openings of the hood enclosing the engine, which has the advantage that the air emerging from the hood in turn has a forced direction - and changes speed.
  • At least one web running in the flow direction is arranged in the cylinder chamber, so that the space surrounding the hood is divided into air duct channels.
  • the air after it has left the cylinder chamber through its air outlet openings, enters a flat chamber which extends oblong essentially parallel to the engine fan axis and perpendicular to the air flow direction.
  • Part of the outer delimiting wall of the flat chamber is therefore flat and at a short distance from the air outlet openings of the cylinder chamber, so that in turn a change in direction and speed of the air flow is forced.
  • the wall delimiting the expansion chamber is formed by an outer wall of the housing in which there are air outlet openings.
  • a microfilter which is fastened in a manner known per se, is arranged here, through which the air leaves the vacuum cleaner.
  • the microfilter arranged at this location results in a further considerable noise reduction. Measurements have shown that the measure can achieve a further noise reduction of up to 3 dB.
  • the air channel-forming webs in the chambers are foam profiles, the surfaces of which are considerably rougher than the walls delimiting the chambers. It is thus achieved that the air has speed differences across its flow cross section, which on the one hand reduces power losses and on the other hand contributes to further noise insulation.
  • Fig. 1 a part of the vacuum cleaner with the vacuum cleaner housing 1, the motor 2 and the fan 3 can be seen.
  • the blower 3 is inserted into the housing by means of the air-tight, vibration-damping profile strip 4.
  • the hood 7 surrounding the motor is airtightly placed on the profile 5 and the holding block 6, so that there is a vibration-damped airtight envelope of the motor.
  • the cylinder chamber 9 is formed, through which the air flow 10 running into the plane of the drawing runs around the hood 7.
  • a web 11 divides the air flow 10 into two flow arms and also provides vibration insulation between the hood 7 and the wall delimiting the cylinder chamber 9.
  • the air outlet openings from the cylinder chamber lie in the region of this wall 12.
  • the flat chamber 14 bounded by a wall 13 extends, and the air flow 10 is deflected by changing its speed by approximately 90 ° and results in the air flow 15.
  • the air flow enters the expansion chamber through the air outlet openings 16, which in turn is limited by parts of the housing outer wall 1.
  • FIG. 2 it can be seen how the air outlet openings 7a of the hood 7 enclosing the engine and the air outlet openings 12 of the cylinder chamber 9 are separated from one another by the partition 17 so that the air flow 10 has to flow around the hood 7 through the cylinder chamber 9 once .
  • the air flow 10 After the air flow 10 has been divided by the vibration-damping web 11, the air flow enters the flat chamber 14 through the air outlet openings 12 of the cylinder chamber 9.
  • arrows 19 indicate how the air flow in the blow-off direction of the engine blower unit impacts against the hood rear wall of the hood 7. It is first forced to change direction by 90 ° so that it can flow, indicated by the arrows 20, through the air outlet openings 7a of the hood 7 into the cylinder chamber 9. Here it again meets the boundary wall 8 of the cylinder chamber 9 and has to make a further change of direction by 90 ° in order then to form the flow arm 10 into the plane of the drawing.
  • These multiple changes in direction also bring changes in speed, which reduces the power losses and at the same time brings with it considerable noise insulation.
  • the airflow-dividing webs have an advantageous vibration-damping effect between the individual walls, so that the vacuum cleaner according to the invention runs smoothly overall.
