Description

Mobile stick vacuum cleaner

The innovation relates to mobile stick vacuum cleaners for the care of floors and carpets, with im Dust filter device housed in the device housing.

In such devices, the dusty air enters through a suction nozzle located on the front part of the device, flows through the chamber above for the Bürstbzw. Tapping roller, enters the filter device one and is after separation of the Sxaubes from the blower promoted outdoors.

Use the most popular upright vacuum cleaners of this type ZUiJ) Separation of the dust filter bags or filter bags, which can be found in a space between the roller chamber and the blower unit. You are by procrastination on a nozzle or by pressing on

an air passage opening firmly connected to the suction chamber. If the dust bag or the dust bag The filter is removed from the device and emptied until it is partially filled with dust. Filter bags are thrown away, while dust bags after emptying and shaking out again in the device to be used «

This well-known principle of filtering, collecting and removing dust is quite cumbersome and unhygienic. If disposable filter bags are used, the device must have an additional filter, That catches the dust if a bag bursts. If the bag is inserted into the dust bag, it works Although the dust bag is used as a safety filter, changing the bag is difficult and unhygienic.

The innovation is based on the task of constructing a device of the type mentioned at the beginning so that that a considerably simplified and hygienically perfect removal of the accumulating dust becomes possible.

The solution to the problem is essentially that, according to the innovation, the dust by a multiple folded cloth filter held by two frame parts is deposited. The dust falls off the downward sloping filter surfaces in the lower part designed as a dust collector

of the device. The lower part of the device can be folded down. The filter device and the brush roller are with connected to the device hood, as well as the rear wall of the roller chamber. For emptying, the device is placed in or held over a garbage can so that it is facing downwards at an angle. Through a Pressing a locking button opens the device and the dust slides under the rear wall of the roller chamber and the roller brush through the air inlet nozzle into the bucket. The lower part snaps into place after the Empties automatically into its old position when the device is placed on the floor.

With this facility, there is no need to change filter bags or clean the filter bag. It saves laborious work processes. It is also not necessary to hand the soiled Touching filters, and you don't have to keep buying filter bags and keeping them in stock which results in a cheaper use of equipment.

An embodiment according to the Neu ^ x-ang is in the drawing and they are shown below further details explained.

The lower part 6 of the device has the shape of a rectangular tub in the exemplary embodiment. Sine partition 7 forms a chamber for the belt drive with the lateral outer wall. A cutout in the front part is designed as a suction nozzle 13. The rear wall 1o of the roller chamber 11 forms the front boundary of the Dust collection space 12, while the cover part 3 with an adjoining partition 14 forms the dust collection space limited at the rear * The entire lower part 6 can be folded down at joints 15. The joints are on the Intersection of the device hood 2 and device base 6 is provided on the rear of the device. Sine locking device on the front of the device, consisting of a spring 16, a button 17 and a recess 18 in the device hood 2 serves as a closure. Celebration 16 is on the goal wall 19 of the device lower part 6 attached.

The borders of the device hood 2 and device lower part 6 carry elastic profiles 2 made of rubber or plastic This makes both parts of the device airtight with one another closed, whereby the negative pressure that prevails in the device presses the device parts together, when the fan is on. The profiles also serve as impact protection.

The air sucked in by the blower unit enters the roller chamber 11 at the suction nozzle 13. By a cutout 21 in the roller chamber wall 1o it generally reaches the dust collecting space 12. A flap valve 22 closes the cutout 21 when the device is switched off so that no dust falls out. The one from the air stream Any coarse dirt carried along falls into the dust collection chamber 12 below, while the finer dust can be seen on the filter 23 drops. It falls from there when the device is switched off.

The filter unit consists of two frame parts 24, in which the filter 23 is inserted. Struts 25 give the filter 23 a multiple V-position with steep Surfaces. This makes it possible to fit one relatively large filter on a small seam. The filter frames 24 close the dust collecting space 12 in an airtight manner against the blower suction chamber 3o.

The filtered air is sucked in by the fan 1, flows through the motor 25 of the fan unit and occurs through slots 26 in the rear wall of the device hood 2 to the outside.

If the device is to be emptied of dust, it is grasped at the lower part of the guide rod 27 and inclined held over a garbage can pointing downwards. When the button 17 is pressed, the lower part 6 of the device folds down and the dust slides through the Air inlet nozzle 13 in the bucket. The folding down is limited by stops 28.
