Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The washing machine to which the present invention is applied, as shown in FIG. 1, is provided in the main body case 10 and has a water tank 11 for fresh water to be washed, and is rotatably installed in the water tank 11. The washing tank 12 is provided. At this time, the water tank 11 is supported in a state where the lower side of the outer surface is caught through the suspension device 13 supported by the inner upper portion of the main body case 10.

The washing tank 12 is provided with a pulsator 16 which rotates forward and reverse to form a washing stream, and rotates the washing tank 12 and the pulsator 16 on the outer side of the lower surface of the water tank 11. A drive device is provided. The driving device is a power transmission device for transmitting power to the driving motor 17 and the driving motor 17 to generate a rotational force to the pulsator 16 and the washing tank 12 simultaneously or selectively. 18 and a belt 19 connected between the drive motor 17 and the power transmission device 18 to mediate power transmission.

In addition, the upper portion of the water tank 11, that is, the upper portion of the main body case 10 is composed of a water supply pipe 21 and the water supply valve 22 as shown in Figure 2 to supply the washing water into the interior of the water tank (11) The water supply device 20 is provided. Here, reference numerals 23 and 24 are detergent dissolving apparatuses for dissolving and dissolving detergent into the water tank 11 using water supplied thereto, although not shown in FIG. 1, the water dispensing apparatus 20 is disposed on the upper part of the main body case 10 together with the water supply apparatus 20. Is installed. And the lower part of the water tank 11 is provided with a drain 15 consisting of a drain pipe 15a, a drain valve 15b and the like to discharge the wash water filled in the water tank 11 to the outside.

In addition, in the upper portion of the main body case 10 adjacent to the water supply device 20 as a characteristic configuration of the present invention, the sterilizing water supply device 30 to produce the sterilized water through the electrolysis of water to spray into the washing tank 12 Is prepared.

As shown in FIGS. 2 and 3, the sterilizing water supply device 30 includes a rectangular reservoir (31) provided with water filled therein and an upper portion thereof opened, and a cover covering the upper portion of the reservoir (31). 32). In addition, the cover 32 is provided with a pair of silver rods 33 and 34 that enter the inside of the reservoir 31 and are submerged in the water in the reservoir 31. At this time, the power is connected to the top of the two silver bars (33, 34) so that the DC power of different poles are supplied.

In addition, the upper side of the reservoir 31 is formed with an inlet 35 so that water can be supplied into the reservoir 31, and the inlet 35 is branched from the water supply pipe 21 passing the water supply valve 22 and extended. The connecting pipe 26 is connected. In addition, the inlet 35 is provided with an inlet valve 36 that blocks the inlet 35 when the water in the reservoir 31 becomes full. At this time, the inlet valve 36 is made of a conventional float valve to block the flow path only when the water is full through the buoyancy opening (36a) and the lever (36b) to rise according to the water level, buoyancy opening (36a) And a water level detecting means (integrated with an inlet valve) for detecting a water level according to the operation of the lever 36b. Here, the water level detecting means is to detect the water level of the reservoir 31 so that power can be applied to the above-described silver bars 33 and 34 only when the water level is full.

This configuration is for making sterilized water with water filled in the reservoir 31, the positive electrode (+) and the negative electrode (-) of the two silver rods (33, 34) submerged in the state filled with water in the reservoir 31 When the DC power is applied, the two silver bars (33, 34) and the water reacts to cause electrolysis so that the silver solution is generated with sterile sterile water. At this time, the DC power applied to the two silver bars (33, 34) is good to stop the power supply when the concentration of the silver solution sterilization water reaches about 5PPM to become sterile.

In addition, the lower portion of the reservoir 31 is formed with a drain hole so that the sterilization water generated through this configuration can be supplied into the washing tank 12, the drain hole 37 to guide the sterilizing water to the washing tank 12. The discharge pipe 38 extending a predetermined length toward the washing tank 12 is provided. In addition, the discharge pipe 38 is provided with a discharge valve 40 made of a conventional solenoid valve that is operated by receiving power to open and close the discharge port 37. The discharge valve 40 is configured such that the blocking plate 43 which moves forward and backward with the amateur 42 when the amateur 42 moves forward and backward in the excitation coil 41 opens and closes the flow path. In addition, a nozzle 39 having a plurality of injection holes 39a is provided at the outlet of the discharge pipe 38 so that the sterilizing water supplied into the washing tank 12 may be evenly sprayed.

The following describes the overall operation of the washing machine according to the present invention configured as described above.

When the user puts laundry into the washing tank 12 and selects and operates the washing course, the water supply valve 22 provided at the upper portion of the main body 10 opens to supply an appropriate amount of washing water to the inside of the water tank 11. do. At this time, the wash water supplied through the water supply valve 22 dissolves the detergent while passing through the detergent dissolving devices 23 and 24 and is supplied into the water tank 11 together with the detergent.

In addition, a part of the water supplied at the same time as the water supply operation of the water tank 11 is also supplied into the reservoir 31 of the sterilizing water supply device 30 through the connection pipe 26 branched from the water supply pipe 21. At this time, when the water in the reservoir 31 is full, the sterilizing water supply device 30 stops the water supply to the reservoir 31 by the operation of the inlet valve 36 consisting of a float valve, the of the inlet valve 36 Through the water level detecting means detects that the reservoir 31 is full. In addition, when it is detected that water is full through the water level detecting means of the inflow valve 31, the DC power is applied to the two silver bars 33 and 34 inside the storage container 31, and the two silver bars 33 and 34 react with water. By causing electrolysis, sterile water having sterility is produced. In other words, the water inside the reservoir 31 becomes electrolytic solution sterilized water after electrolysis for a predetermined time.

On the other hand, when the wash water is filled in the water tank 11, the washing machine performs the washing stroke while the pulsator 16 is rotated, and then performs a rinsing stroke to repeat the water supply and drainage several times. After the rinsing cycle is finished, a dehydration stroke is performed to dehydrate the laundry.

At this time, the washing machine according to the present invention is the drainage opening 37 is opened by the operation of the discharge valve 40 of the sterilization water supply device 30 in the initial stage of the dehydration stroke through the sterilization water produced during the washing stroke through the discharge pipe 38 It is supplied to the washing tank 12. That is, the sterilization water in the storage tank 31 is sprinkled on the laundry in the washing tank 12 while performing the dehydration process, and the bacteria remaining in the laundry are sterilized. At this time, since the nozzle 39 having a plurality of injection holes 39a is provided at the outlet of the discharge pipe 38 of the sterilizing water supply device 30, the sterilizing water is sterilized while the sterilizing water is evenly sprayed in the rotating washing tank 12.

As described in detail above, the sterilizing water supply apparatus of the washing machine according to the present invention by spraying the sterilized sterilized water generated through the electrolysis of the silver rod and water to the laundry inside the washing tank during the dehydration operation of the washing machine, bacteria remaining in the laundry It is effective to sterilize.
