2 is a view for explaining a washing method of a conventional washing machine.

Referring to FIG. 2, the washing machine is turned on (St 1). Then, the user selects the desired washing course (St 2), and presses the operation button (St 3).

When the operation button is input, the amount of the laundry cloth in the washing tank is sensed (St 4). Then, according to the amount of laundry cloth detected, washing is performed by a predetermined process of performing water supply (St 5), washing (St 6), rinsing (St 7), and dehydration (St 8).

In addition, since there is a lot of dirt on the laundry cloth, when a large number of laundry is combined and washed, contaminants are moved to another laundry cloth, and there is a problem that bad bacteria are transferred and propagated throughout the laundry. In particular, underwear such as lingerie is an article directly touching the human body, which causes many problems when bacteria are moved and multiplied.

In order to improve such a problem, recently, more and more antimicrobial agents are used during washing, and the increasing use of antimicrobial agents adversely affects the health of users.

Therefore, in recent years, a method of washing is proposed using a natural antibiotic silver (Ag), as a specific embodiment of the Korean Patent Publication No. 2002-0012368, "Sterile water supply of the washing machine" , Korean Patent Laid-Open No. 2002-0012369, has been proposed by the "control method of a washing machine having a silver solution manufacturing apparatus".

However, the conventional washing machine does not have a specific way to control the silver ions, there was a problem that can only perform a sterilization washing of a single concentration. In other words, although the degree of sterilization varies with time according to the concentration of silver ions, it was not possible to produce a silver solution in which a constant concentration of silver ions were accommodated.

In addition, when a silver solution containing silver ions having the same concentration is applied to a cloth with a lot of dirt or a lot of messy cloth, there is a problem that complete sterilization washing cannot be performed.

The present invention is proposed to solve the problems as described above, it is an object of the present invention to propose a washing machine capable of adjusting the sterilization strength that can increase the user's convenience by manipulating the concentration of silver ions.

In addition, an object of the present invention is to propose a washing machine capable of adjusting a sterilization strength capable of producing a silver solution in which a desired concentration of silver ions are accommodated by a simple operation of a switch, so that sterilization washing can be performed more reliably.

In addition, it is an object of the present invention to propose a washing machine that can control the sterilization strength can be implemented according to the characteristic state of the cloth can be controlled sterilization strength.

Referring to FIG. 6, the power supplied from the feeders 35 and 45 has a circular cross section, and is a silver anode 331 that is formed in a straight line as an anode to generate silver ions (Ag ⁺ ). The electrolytic tube 332 is formed to face the silver cathode body 331 so that a cathode power is applied and is formed long. Water flows through the space between the silver anode body 331 and the electrolytic tube 332, and silver ions dissolved from the silver anode body 331 are mixed in the flowing water to form a silver solution. The electrolytic tube 332 and the silver positive electrode body 331 may not be circular, but may have other shapes such as a square and a pentagon.

The silver anode 331 may be formed of silver having a purity of 99.9% or more.

In addition, silver is not necessarily used as a material of the electrolytic tube 332, and may have an ionization tendency similar to silver, and copper may be used as an example. Furthermore, another conductive material may be used. Furthermore, stainless steel which is easy to obtain may be used. In addition, the inlet of the electrolytic tube is connected to the tube into which the wash water flows, the water discharge port can be discharged to the tub directly through the electrolytic tube toward the tub of the washing machine.

Then, the control unit 13 is delivered to the silver solution manufacturing unit (see 16 of FIG. 3) to operate so that the appropriate silver ions are included in the silver solution.

The method of controlling the silver ion concentration of the silver solution may be possible by controlling the flow rate and the voltage in the structure shown in FIG. 6. In the structure in which the silver solution reservoir is formed and the electrode is contained therein, it may be possible by adjusting the voltage applied to the electrode.

In detail, when a high concentration of a silver solution is required, that is, when a cloth with heavy contamination is washed, a strong negative ion is selected in the negative ion level control unit 36 or a strong negative ion is selected by a rotary switch. In this case, the silver solution of high concentration can be obtained by slowing the flow rate and applying a high pressure. When a low concentration of silver solution is required, that is, when cloth with less contamination is washed, medicine is selected in the negative ion level control unit 36 or weak negative ions are selected by a rotary switch. In this case, the silver solution of low concentration can be obtained by slowing the flow rate and applying a low pressure.

The voltage may be transferred to the silver solution preparing unit 16 so that the applied voltage is changed. In addition, the flow rate signal may be possible by controlling the amount or the water pressure of the silver wash water that is supplied to the silver solution supply / drainage unit 15 and is supplied.
