While the circulation pump 8 pumps the water for washing, supplied to the circulation pump 8, from the bottom of the tank 2 for water circulation pipe 7 so as to allow draining of water for washing from the top of the tank 2 for water.

The sterilizer 100 is mounted above the circulation pump 8, to ensure that the sterilizing function through the production of silver ions in the electrolysis process or activation generated silver ions.

Figure 2 presents a perspective view with exploded parts of the design of the sterilizer shown in figure 1.

The sterilizer 100 includes a container 110 having an inlet hole 110a with an open upper surface, through which water for washing is supplied to the sterilizer 100, and the exhaust port 110b, through which about what goes down the sink water for washing.

Between the inlet 110a and the outlet 110b connected to the circulation pipe, and the upper open surface of the container 110 is installed, the cover 120, and the cover 120 is installed first and the second electrodes 130 and 140 forming the electrodes for electrolysis.

The first and second electrodes 130 and 140 are installed in the container 110 through the openings 120a and 120b in the lid 120 and the passage of water wash through the container 110 immersed in it.

In addition, the first and second electrodes 130 and 140 are in the form of plates, as shown in figure 2, facing towards each other and are mounted parallel to the direction of flow of water for washing in the container 110.

Figure 3 presents a schematic view of the internal structure of the washing machine shown in figure 1.

Tank 2 water is installed in the housing 1 of the washing machine and the drum 3 is installed in the tank 2 for water.

Vodopada valves 5, which feeds water into the tank 2 for water, connected to the device 6 for supplying detergent through the transportation pipe 11 in the upper part of the tank 2 for water and inlet and outlet openings 3b, 3a, performed respectively in the upper and lower parts of the tank 2 for water.

The circulation pipe 7 forming the channel 20 of the circulation by connecting the outlet and inlet holes 3b, 3a, connected with the outside of the tank 2 for water, and the circulation pump 8 and the sterilizer 100 is connected to the channel 20 of the circulation.

The inlet opening 3a is used as a conduit for draining water for washing in tank 2 for water, and three-way valve 9 is installed in the lower part of the inlet 3a to switch channel flow of water for washing, providing a direction of water for washing, introduced through the inlet opening 3a, the drain pipe 12 or the circulation pipe 7.

In the outlet 3b installed nozzle 21 that enables the distribution and pour out the water wash over a large area. The discharge hole 3b and the nozzle 21 is installed in the upper part of the tank 2 water so that the discharge into the tank 2 water ensure uniform distribution of water for washing, passing through the sterilizer 100 in the drum 3 and the tank 2 for water.

At the start of the washing process or the rinsing water for Laundry to fill the tank 2 water to a specified level, and the sterilizer 100 is placed above the water level for washing. In accordance with a non-working state of the circulation pump 8, the electrodes 130 and 140 in the sterilizer 100 is not immersed in water for washing to prevent contamination of the sterilizer 100 water remaining at the end of the washing process or rinsing. In addition, it allows you to prevent electric shock in case of unlock the door due to the occurrence of the malfunction of the washing machine or other problems.

These two electrodes 130 and 140 sterilizer 100 is connected to the block 30 power supply providing power to the electrodes 130 and 140. Block 30 power supply converts the electric current and provides power to the electrodes 130 and 140 DC.

The polarity of the direct current supplied to the electrodes 130 and 140, may be changed by the controller 40, which controls the block 30 power.

The sterilizer 100 operates in two modes. In the first mode, the first electrode 130 serves as the anode, since the positive polarity (+) DC controller 40 is supplied to the first electrode 130 and the second electrode 140 serves as the cathode, since the negative polarity (-) constant totipotence on the second electrode 140. In the second mode, the polarity of the electrodes are reversed with respect to their polarities in the first mode, that is, the first electrode 130 serves as a cathode and the second electrode 140 to the anode.

In the first mode, the first electrode 130 containing silver as the anode to ensure selection of silver ions into the water for washing. That is, the first electrode 130 and the second electrode 140 are respectively the anode and cathode, and these two electrodes of the electric current. In addition, the silver in the first electrode 130 is subjected to electrolysis, in which silver ions are produced in the state

Ag+and these ions are served in the circulating water for washing.

In the second mode, the polarity of the first and second electrodes 130 and 140 are reversed with respect to their polarities in the first mode, that is, the second electrode 140 containing titanium, is the anode and the first electrode 130 (electrode made of silver) - cathode.

In this case, the silver ions are not allocated to the first electrode 130 and the second electrode 140 is not subject to electrolysis. Accordingly, ions (e.g., Ti+) are not produced in the second electrode 140, and passing an electric current between the first electrode 130 and the second electrode 140 is provided at the expense of the electrolyte present in the water for washing, or ions produced by the detergent.

In this second is egime ions for sterilization is not directly produced, but ions contained in the water for washing, are activated. That is, the electrolysis can be provided by the ionization of compounds in the neutral state, contained in water for washing.

In particular, if the selection of silver ions into the water for washing in the first mode, the concentration of silver ions in the sterilization process is reduced and they become electrically neutral, the sterilization effect disappears. Thus, the electrolysis can be provided for the recovery of silver ions in a neutral state in the silver ions.

In the second mode, the bacteria contained in the water for washing, sterilized electric current flowing between the first electrode 130 and the second electrode 140. That is, when passing water wash between the first electrode 130 and second electrode 140 under the action of electric current may occur partial destruction of the cell membrane of the bacteria contained in the water for washing, or the formation of pores in this cell membrane.

Under the action of electric current cell membrane of bacteria is destroyed and ceases to exist. Even if the destruction of bacteria does not occur, the silver ions have the ability to easily penetrate into bacteria. If silver ions were allocated to the wash water in the first mode, due to the penetration of silver ions p is oshodi destruction of bacteria.

The action of the electric current flowing between the first electrode 130 and second electrode 140, bacteria increases in proportion to the density of electric current flowing between the two electrodes 130 and 140, that is, the strength of the electric current on the unit square.

Sterilizing function in the first and second modes described above can be applied in different ways during the entire washing process, and below is a description of embodiments relating to the sterilizing function.

In one embodiment, the sterilizer 100 operates in the first mode for selecting ions of silver, and after a predetermined period of time is switching from the first mode to the second mode.

This is usually used in relation to the processes of washing and rinsing. Figure 3 in a state where the water for washing is supplied into the tank 2 water through vodopada valves 5 and the device 6 supply of detergents, and the three-way valve 9 connects the inlet opening 3a with the circulation channel 20 to form a channel 20 of the circulation when the pump is in operation 8 water for washing circulates through the circulation channel 20 and the sterilizer 100 is connected to the channel 20 of the circulation.

Since the sterilizer 100 operates in the first mode, the silver ions are allocated to the first electrode 130 to the wash water, and water with the Irka, contains silver ions, is injected into the tank 2 for water and the drum 3 through the nozzle 21, showing, thus, bactericidal and sterilizing functions.

After a predetermined period of time the sterilizer 100 starts to operate in the second mode. That is, the cell membrane of the bacteria are exposed to an electric current flowing between the two electrodes 130 and 140, which under the action of silver ions is the destruction or killing of bacteria. In addition, in the second mode, the activation of the money that was allocated in the first mode and the concentration of which has been reduced in the process of sterilization of bacteria or other operations.

Recovery of spent silver ions is in the process described above, so that the duration of operation in the first mode can be reduced, and thus, the consumption of silver in the first electrode can be reduced.

In another embodiment, the sterilizer 100 operates first in the second mode, and then in the first mode. Initial work sterilizer 100 in the second mode due to the fact that silver ions released during the washing process, can influence detergent high density, dissolved in water for washing, and other ions, and sterilizing function of silver ions can be the ü violated. In the process of washing the sterilizer 100 operates in the second mode, and provides the possibility of sterilizing functions under the action of electric current between the first electrode 130 and second electrode 140, and then in the process of rinsing the sterilizer 100 starts to operate in the first mode, in which the density of the detergent is reduced and the water for washing, you can apply silver ions.

In another embodiment, the washing machine may operate in the mode of washing, in which the water tank and drum are separate from washing processes before washing and rinsing.

Wash cycle corresponds to a special washing process to remove biofilms formed in the water tank and the drum due to the spread of bacteria. That is, in the condition in which water for washing is supplied into the water tank without underwear, the circulation pump 8 operates to circulate water for washing, and the sterilizer 100 operates in the second mode or the first mode.

To improve the efficiency of washing with circulating water for washing can be used feeder salt (not shown)providing a supply of salt in the water. Feeder salt can be installed in a washing machine as an additional device or may be performed in the hopper device 6b is a 6 supply of detergents (see figure 1).

As dissolving salt in water for washing in the electrolysis process produces HOCl. As the reaction conditions for the formation of HOCl known to experts in the art, their detailed description is not included in this description.

The manifestation of sterilizing function HOCl formed in the sterilizer, due to its strong oxidizing ability, providing the ability to effectively prevent the formation of biofilms or their removal by the cleaning tank 2 water drum 3 with HOCl.

In a washing machine according to the present invention described above, it is possible to achieve maximum sterilizing effect by using a small quantity of silver, and this effect can last throughout the entire washing process, resulting in the use of the circulation pump can provide sterilization is not only harmful microorganisms present in lingerie, but also microorganisms that remain or grow in the washing machine, and, thus, to prevent secondary pollution of linen.
