Description

Solution

Clip-in brush units 4 attached to the hole field 2 of the washing drum 1, or brush strips 17 arranged on both sides of the laundry carriers (stabilizers) 3, smoothly caress the alternately rotating dirty laundry soaked in the washing solution 1 o and loosen the softened dirt particles 9, which are rinsed off during the immersion process and absorbed by the washing solution 1o and combine with it, whereby the time required for the cleaning process, the energy required, the amount of detergent, the amount of contaminated waste water and the amount of drinking water used can be almost halved.

Clip-in brushes for washing machine drums

The invention relates to clip-in brush units and brush strips in washing machine drums of any kind, for intensifying the washing processes, saving detergent, washing water and energy requirements, in order to achieve effective environmental protection by reducing river water contamination as a result of chemically contaminated waste water discharges, as a unit of the type specified in the preamble of patent claim 1.

It is known that washing machine drums have stabilizers on the inside which, when they rotate and come into contact with water, promote the washing effect, whereby the detergent additives, supported by the electrical water heating, dissolve the dirt particles within the laundry, which are then rinsed out by the alternating rotation in the water bath.

Disadvantage: high detergent consumption, high energy costs, high water requirements, long washing times, chemically contaminated waste water discharged into rivers leaves visible environmental damage and dangers to drinking water and life.

It is well known, particularly in car washes, that brush rollers made of fabric parts can achieve the desired washing effect when constantly flushed with water.

It is not known that in washing machines for laundry in general brush parts are arranged on the inner surface of a washing drum or on both sides of the stabilizers.

The invention is based on the object of achieving the brush effect on the dirty laundry that is constantly submerged in water as it passes by by simply clipping brush units onto the inner wall or stabilizers of the washing drum of a commercially available new or used washing machine with alternating rotation, and of intensifying the washing process, making it more economical, energy-saving and environmentally friendly, without causing damage to the laundry fabric during spinning.

The essence of the invention is the protection of the environment and the reduction of pollutants in waste water by reducing the chemical additives, water impurities and dirt removers in our rivers and seas.

The essence of the invention is halving the washing time, saving electrical energy and reducing the consumption of drinking water, without affecting the required degree of cleaning.

The purpose of the invention is to wash laundry economically, while preserving the environment and nature, rivers and lakes to a large extent for life and health.

The invention is explained in more detail below using the drawing as an example: this shows in

Figure 1 shows a cross-section of a washing drum with clipped-in brushes, each offset between the stabilizers in the functional state, according to the invention;

Figure 2 shows a side section of three brush strips clipped and screwed onto the laundry carriers (stabilizers) in the washing drum, according to the invention;

Figure 3 In plan view, a brush unit consisting of the sheet metal shell with inserted and wired brush tufts, which are fastened with at least two pop rivets, according to the invention;

Figure 4 A top view of the sheet metal shell with recesses for brush tufts and fastening holes for pop rivets according to the invention;

Figure 5 A side view of a brush tuft according to the invention.

In the embodiment shown in Figures 1 and 2, clip-in brush units 4 are arranged in the washing drum 1 in the hole field 2, in multiple rows, each offset, or brush strips 17 are arranged on the laundry carrier stabilizers 3, whereby the brush units 4, 17 are pushed into the existing openings 5 with light pressure and are fastened with at least two pop rivets 6, so that the rotating laundry 7 is touched by the brush tufts 8 in both directions of rotation and the dirt particles 9 are mechanically stripped off from the laundry fabric pores 7 after each washing in order to bind them again in the washing solution Io.

Figure 3 shows the sheet metal shell 11 with recessed fastening holes 13 and pressed holes 14 for receiving the brush tufts 8, the edge zones 15 of which, after insertion, are connected and linked with wire 16 to form a brush strip 17,4, whereby the fastening edge 18 is slightly conical 19 all around and has guide knobs 20 and fastening holes 13.

Figure 4 shows the sheet metal shell in its structural design, otherwise as described above.

Figure 5 shows a brush tuft 8 with inserted wire 16 as it is drawn into a pressed hole 14 of the sheet metal shell 11.

The illustrated and described figures 1 to 5 make it clear that with little effort a lot of energy can be saved, the water requirement and the amount of waste water (the washing liquor produced) can be significantly reduced, which also has a positive effect on the cost-performance ratio, the economic efficiency of a washing machine, and environmental protection.

and promotes nature conservation, in particular by supporting the cleanliness of our waters in rivers, lakes and seas. Our drinking water, the expensive liquid, is too valuable to be wasted as utility water.

How many unemployed or disabled people could find new work here, because every household has a washing machine. With about 30 million washing machines, our rivers could be relieved by about 1.8 million cubic meters of washing water per week and the same amount could be available unused as drinking water, about 15 million kWh could be saved per week
for the sake of the environment.
