It purifies it from the dirt on it by going through the steps. These soils are The forces that allow it to stick on it are the adhesion forces and the washing process For this to happen, these forces must be defeated. In order for the washing machine to overcome these forces between the dirt and the textile surface, The effects on the environment it creates are collected in four main groups: washing chemistry (detergent), mechanical effect, temperature and application time. With the help of these effects By reducing the surface tension forces between the textile surface, dirt is removed from the surface. being removed. Water-soluble dirt is taken into the water, very little in the water. Soluble residues are discharged after each washing step and removed from the environment. being removed.

Washing temperature is essential for washing performance as well as for energy consumption. is one of the parameters. Reducing the washing temperature reduces energy consumption, namely It will also decrease the row washing performance. Washing machine performance can be improved with longer wash times. However, the washing time long is a situation that the user does not want and the textiles being washed are also causes wear. For this reason, the short washing time as important as performance. Washing with the use of vacuum washing technology in the washing machine Washing times can be shortened by increasing the performance.

On the other hand, the surface tension of water is very high. Wetting the textiles to be washed The process can only be carried out by lowering the surface tension of the water with detergent and the water It takes place quickly and effectively by heating. Heating process water molecules to decrease the surface tension by weakening the cohesion bonds between them.

Another way of reducing the surface tension by weakening the cohesive bonds of water molecules is Another method is to lower the pressure.

Adhesion of water to textile by decreasing surface tension of water under vacuum the air in the pores in the textile product structure is vacuumed, It is ensured that the textile can be easily wetted and the detergent is mixed with water. It is ensured that it can easily enter between the pores. Your water (and detergent) easier penetration into the textile under vacuum, long cleaning cycles It will also reduce the wear of the laundry.

On the other hand, for a certain washing performance, there is a difference between washing temperature and time. There is an inversely proportional relationship. The higher the wash water temperature, The duration of the following continuous cycle wash can be reduced by 0. reverse wash If the time is increased, the same washing performance can be achieved by washing at a lower temperature. obtainable. In this way, the washing setting temperature required by the washing programs a few degrees lower than normal. Energy savings in this way washing performance can be maintained. Washing temperature in figure 1- The relationship between the washing time can be seen.

DORA, 2007) set temperature determined for Cotton-60 program in the thesis document the lower the heating time, the energy consumption and the main wash for the same water inlet temperature. The end temperature was also found to decrease in parallel (Figure 2). In this analysis, heating 12% of the heating time, energy consumption when the set temperature of the water is lowered from 52°C to 50°C. It was determined that the consumption decreased by 10%.

DORA, 2007) for the Cotton-60 program in the analysis made in the thesis document When the amount of washing water is reduced from 16 liters to 12 liters, 19.83% of the heating time and it was determined that energy consumption decreased by 16.6% (Figure 3) Description of the Invention: The machine described in the invention is used for water (hence detergent) under negative pressure. Faster and more effective penetration into the laundry to be washed compared to the atmospheric pressure machine. the lowest washing temperature and the shortest washing time using the washing feature and therefore, it will provide the lowest energy requirement.

In order to lower the surface tension of water in the machine described in this invention, instead of temperature Heating energy is saved by using negative pressure effect. in the find negative pressure to the main wash water and rinse water in the described machine Thanks to its faster and more effective penetration into the laundry to be washed by applying It will provide lower water consumption.
