The present invention relates to a sterile washing method performed in a washing machine in which a silver solution forming unit is formed, and in particular, a small silver solution is used by spraying a silver solution prepared by a silver solution forming unit mounted inside a pulsator type washing machine. The present invention relates to a sterile washing method using a silver solution which provides the best sterilizing effect.

1 is a functional block diagram for explaining the configuration of a general washing machine.

Referring to FIG. 1, a conventional washing machine includes a key input unit 1 for allowing an operating state of a washing machine to be manipulated by a user, and furthermore, functions such as washing temperature, dehydration speed, rinsing frequency addition, washing course selection, and the like, are inputted. A sensor unit 2 for detecting information necessary for washing such as washing temperature, water level and weight of laundry, and a series of washing based on the washing mode and washing information inputted through the key input unit 1 and the sensor unit 2 Storing information related to an operation mode related to the washing, rinsing, and dehydrating strokes corresponding to the washing mode input through the key input unit 1 and the controller 4 for controlling washing, rinsing, and dehydrating strokes of the washing machine. Storage unit 3, the motor drive unit 6 for washing, rinsing and dehydrating by rotating the motor forward and reverse according to the control signal of the control unit 4, and washing properly according to the washing, rinsing and dehydrating stroke Watering and drainage The water supply / drainage driving unit 5 for driving the valve formed in the conduit and the display unit 7 for controlling the driving state of the washing machine and the operating state of the washing machine Included.

When the operation of the conventional washing machine is sequentially described, first, when the user instructs the operation course and the operation mode of the washing machine through the key input unit 1, the control unit 4 detects the detection signal detected by the sensor unit 2. And based on the information stored in the storage unit 3 to predict the future operation of the washing machine to be instructed.

In addition, the controller 4 issues a predetermined operation signal to the water supply / drainage driving unit 5, the motor driving unit 6, and the display unit 7 so that the entire washing machine operates correctly.

On the other hand, the washing machine is a mechanism for washing using the wash water, because many dirty laundry cloth, in order to prevent bacterial contamination due to such dirt was often added with a chemical disinfectant with detergent.

In addition, in recent years, in order to sterilize a laundry cloth, a washing machine having a sterilization function for receiving silver ions in a laundry is further introduced. Washing machine which is further formed with such a sterilizing function is disclosed in Korean Patent Publication No. 2002-0012368, "Sterile water supply device for a washing machine", Korean Patent Publication No. 2002-0012369, "Control method of a washing machine having a silver solution manufacturing apparatus" Suggested by

However, the silver solution forming portion formed in such a conventional washing machine simply suggests that the silver solution forming portion is formed as one part of the washing machine, and thus, it is not suggested at what time of the washing process the spraying of the silver solution is preferable for the sterilizing effect.

On the other hand, in recent years, in order to sterilize kitchen utensils, underwear, etc., heat or a chemical agent added to water is increasing. However, this method is an additional cost because the chemicals are used, there is a problem that is harmful to the human body when used in excess.

In addition, since the silver solution used for performing the sterilization washing is an expensive silver solution, when the spraying is not performed at an appropriate time, the effect of sterilization cannot be expected while the silver solution is used.

The present invention has been made to solve the problems as described above, and aims to propose a method that does not waste expensive silver solution by suggesting an appropriate time interval at which the silver solution can be spread.

In addition, an object of the present invention is to propose the most suitable time for spraying the silver solution in terms of enhancing the sterilization effect.

Furthermore, the present invention proposes a washing machine and a washing method that do not require a chemical sterilizing agent, and thus aims to propose a preferable sterilizing method which is harmless to the human body.

Sterilization washing method using a silver solution according to the present invention for achieving the object as described above is the step of washing, washing, rinsing, dehydration, rinsing dehydration repeated process to remove dirt and detergent residues: dirt and detergent residues After completely removed, the silver solution is sprayed on the intermittent dehydration section of the dehydration section for the sterilization process; The step of discharging the silver solution is sufficiently carried out while the separation section is performed in the laundry cloth sufficiently wetted with the silver solution.

The silver solution can be used more efficiently by the method as described above. In addition, since there is no need for chemicals to be used by using the silver solution as a disinfectant, there is no fear of impairing the safety of the washing machine user.

In addition, there is an effect that can increase the sterilization effect by allowing the appropriate timing of the addition of the silver solution.

Hereinafter, with reference to the drawings propose a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the present embodiment, and those skilled in the art who understand the spirit of the present invention can easily change, easily delete, and easily add another embodiment included in the scope of the present invention. It can be easily proposed by the method.

2 is a perspective view of a pulsator washing machine to which the idea of the present invention is applied.

Referring to Figure 2, the washing machine according to the present invention is formed in the case 20 and the case 20 to form an exterior, the drum to cause friction between the laundry cloth by the rotational movement to remove the time ( 21, a silver solution reservoir 23 formed on one side of the case 20 to store the silver solution as sterilized water, and one end of the silver solution reservoir 23 is connected to the other end of the drum 21. Spray nozzle 24 for spraying the silver solution toward the upper side of the panel, an operation panel 22 for the user to observe and operate the operating state of the washing machine, and a drum 21 to cover the upper side of the case 20. Cover 25 for opening and closing the upper side of the is included.

In addition, as one button for the operation of the washing machine, one button of the operation panel 22 is further formed with a sterilization washing button 26 for operating in an operating state to perform sterilization washing.

When the sterilization washing button 26 is operated, a series of processes for sterilization washing are performed.

In brief, the process of sterilization washing is performed after washing, rinsing, and dehydration. After washing is performed, silver solution is sprayed during dehydration, which is the final stage of washing, and silver solution is put into the cloth. By contacting the fabric, the bacteria transplanted into the laundry cloth are killed.

The silver solution is prepared through a silver solution forming part which has already been proposed in the prior art, and then stored in the silver solution reservoir 23, and the silver solution stored in the silver solution reservoir 23 is spray nozzle 24. It is sprayed toward the laundry cloth accommodated inside the drum 21 through.

Hereinafter, a washing method according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart illustrating a sterilization washing method using a silver solution according to the present invention in sequence.

Referring to FIG. 3, the method for sterilizing washing according to the present invention first turns on a washing machine by turning on a power (St 10), selects a specific washing course (St 11), and selecting the washing course (St 11). ), The silver solution will be sprayed if the sterilization washing course or the lingerie washing course, etc., in which sterilization operation is preferably performed, is selected.

When the washing course is selected and washing starts to be performed, the degree of resistance to the forced rotation of the drum is evaluated by the operation of rotating the drum (St 12), and the quantity is detected by the evaluated resistance (St 13). After the amount of laundry is detected, water is supplied (St 14), washing (St 15), rinsing (St 16), dehydration (St 17), rinsing dehydration repetition, and final rinsing (St 18) are sequentially performed. The rinsing dehydration repeat and the final rinsing (St 18) is a process for completely removing the fine dirt or detergent residues stuck on the laundry cloth, the more the number of repeated cycles, the higher the cleanliness of the laundry cloth.

After the process as described above, after the fine dirt or detergent residues on the laundry cloth is completely removed, the sterilization process and the final dehydration process is performed by spraying the silver solution (St 19). The sterilization process is carried out at the beginning of the dehydration process so that after the dehydration is completely done, there is little silver solution left in the cloth, thereby preventing discoloration and discoloration of the cloth, which may be caused by a chemical reaction between the silver solution and the cloth. Do it.

When the above sterilization and final dehydration process is finished, all the washing process is finished, and when the laundry cloth is dried, it ends.

Hereinafter, the whole process of dehydration is proposed in detail by the graph of the rotational speed and time of the drum in the sterilization and final dehydration.

4 is a view for explaining a sterilization method using a silver solution according to the present invention.

Referring to Figure 4, the sterilization laundry according to the present invention, the sterilization is performed by spraying the silver solution in the sterilization and final dehydration process, the rotational speed of the drum is not increased rapidly, but gradually increases It can be seen that.

In FIG. 4, the cloth unwinding section P1 is a section in which a process of increasing and lowering the speed intermittently for a predetermined time is repeated several times so that the laundry cloth tangled during washing, rinsing, and rinsing dehydration repetition before final dehydration is repeatedly performed. . During this period, the tangling between the laundry is released, so as to prevent damage to the laundry that may be in the dehydration process.

After the fore unwinding period P1 has passed, a balancing period P2 is performed. The balancing section P2 is a section for uniformly spreading the laundry cloth that is unevenly spread inside the drum. In other words, it is to reduce the amount of vibration that may be during the dehydration time by allowing the laundry cloth that may be concentrated on one side of the drum to spread throughout the inner peripheral surface of the drum.

After the balancing section P2 is finished, a mass dewatering section P3 is performed so that the rotational speed of the drum fluctuates within the section of the highest speed 400 rpm (RPM 2) and the lowest speed 200 rpm (RPM 1). The mass dehydration section (P3) is a wash cloth containing laundry cloth is dehydrated much in the early stage of the dehydration process, reflecting this, washing water that is still not discharged in the initial dewatering section, and accumulated in the tub, normal dehydration (aka, It is intended to influence the rotation of the drum in the "bontal section") section, or to bounce back so that it is not absorbed again by the laundry cloth.

The above-described defoaming section P1, balancing section P2, and mass dewatering section P3 are collectively referred to as intermittent dehydration section P4 (aka, "intermittent section").

After the intermittent section P4 has elapsed and the large amount of water is completely discharged to the outside of the washing machine, the drum is rotated at the highest rotational speed up to a maximum rotational speed of 1000 rpm (RPM 3) and the main section P5 is performed. Be sure to

In the dehydration rate graph of the washing machine as described above, the silver solution is preferably sprayed in the interval until the end of the intermittent dehydration interval (P4) after the balancing period (P2) has elapsed. This is because it is preferable that the laundry cloth is uniformly positioned on the inner circumferential surface of the drum in order to uniformly wet the silver cloth sprayed from a certain position.

In addition, when the silver solution is sprayed in the separation section P5, which is a rotational speed that is too fast, it is not preferable because the silver solution is swept onto the inner wall of the drum before the silver solution is soaked in the laundry cloth by the strong air flow, and before being soaked in the laundry cloth. It is not preferable because it is discharged to the outside of the drum. Furthermore, since the silver solution soaked in the cloth cannot afford to be discharged to the outside, the silver solution may soak into the cloth and decolorize even after dehydration.

 In addition, in a state where too much water is soaked in the laundry cloth (for example, the bleeding section), since the concentration of the silver solution is reduced due to the water originally wetted in the laundry cloth, a good sterilizing effect cannot be obtained. Not preferred. In addition, it is not preferable to use a high concentration of silver solution to obtain a normal sterilization effect.

As a result, in order to smoothly sterilize the laundry cloth, it is preferable that the silver solution is sprayed after the balancing section P2 and before the main separation section P5 starts.

Furthermore, it may be carried out at the rear of the mass dewatering section P3 after a large amount of wash water is discharged to some extent. That is, after about half of the time of the mass dehydration section P3, the silver solution may be sparged, and further, may be made just before the start of the mass dewatering section P3.                     

As described above, the sterilization washing method using the silver solution of the present invention proposes a section suitable for spraying the silver solution, thereby increasing the sterilization effect and reducing the silver solution.

By suggesting an appropriate time interval at which the silver solution can be sparged by the present invention, there is an effect of not having to waste expensive silver solution.

In addition, the present invention has the effect of increasing the sterilization effect by spraying the silver solution during the appropriate section.

In addition, since the present invention does not use a chemical disinfectant or the like, there is an advantage that the disinfection effect of the cloth can be obtained while being harmless to the human body.

In addition, since the silver solution remaining on the cloth can be reduced, there is an effect of preventing discoloration of the cloth, which may exist depending on the type of the cloth.
