FIG. 1 is a schematic view for explaining a water supply system of a dishwasher having a dual sterilizing function according to an embodiment of the present invention. FIG. 2 is an exploded perspective view showing a detailed configuration of the sterilizing water generating module of FIG. do.

1, a water supply system of a dishwasher according to an embodiment of the present invention includes a water supply pipe 10, a water supply inlet pipe 20, a sterilization water generation module 30, a sterilization water supply pipe 40 A sterilizing water inlet pipe 50, and an ultrasonic vibrator 60.

Here, the water supply pipe 10 is a conventional pipe which is installed in the dishwasher so that the water discharged from the water supply port can be supplied to the washing water of the dishwasher, thereby providing a water path for the water.

The tap water inflow pipe 20 is connected to the tap water inflow pipe 20 in such a manner that a part of the tap water flowing in the tap water supply pipe 10 is discharged through an underwater discharge Thereby supplying a part of the water to the sterilizing water generating module 30 so that the sterilizing water can be generated.

If the flow rate of the tap water flowing in the tap water supply pipe 10 and the tap water inflow pipe 20 is not controlled, Or may be supplied in an excessively large amount to the water supply pipe 20.

That is, when the water supply pipe 20 is supplied with a small amount of water or an excessive amount of water, it is difficult to expect a sterilizing effect or a sterilizing effect at a certain level or more when it is used as washing water in a dishwasher, It is necessary to appropriately adjust the amount of water supplied to the water inlet pipe 20 according to the desired amount. Therefore, in the present invention, the metering valves 11 and 21 are installed in the water supply pipe 10 and the water supply pipe 20, respectively, so that a certain amount of water can be discharged only in one direction.

In this case, it is preferable that the metering valve 11 installed in the water supply pipe 10 is installed between the water supply pipe 20 and the sterilization water supply pipe 40, To allow a part of the water to flow toward the water inlet pipe 20 and the other part to be mixed with the sterilized water discharged from the sterilization water supply pipe 40 in an appropriate amount.

The metering valve 11 provided in the water supply pipe 10 allows 70% of the water supplied into the indoor water to flow out and the metering valve 21 provided in the water supply pipe 20 is supplied to the indoor It is desirable to make 30% of water supply possible.

That is, the washing water supplied to the dishwasher is most ideal for obtaining a germicidal effect by mixing the mixing ratio of the water and the sterilized water to 7: 3. In the water supply pipe 10 and the water supply pipe 20 If the valves 11 and 21 are set at a flow rate ratio of 6: 4 or 5: 5 rather than a ratio of 7: 3, the sterilizing water generating module 30 The volume of the sterilizing water producing module 30 must be increased, thereby increasing the manufacturing cost of the sterilizing water producing module 30. [

A sterilization water generating module 30 is connected to the end of the water supply inlet pipe 20. The sterilization water generating module 30 discharges a part of the water supplied from the water supply inlet pipe 20 An electrode unit 32 and a PCB substrate 33 which serve to generate sterilized water while simultaneously supplying the sterilized water generated in the sterilization water supply pipe 40 to the sterilized water supply pipe 40. [

The case 31 has an inlet and an outlet at each end of the case so that the case 31 is connected to the water inlet pipe 20 and the sterile water supply pipe 40, An internal space is formed. In this case, when the capacity of the inner space of the case 31 is too small, the supply flow rate of the sterilizing water supplied to each of the faucets is small and the use becomes inconvenient. Conversely, when the capacity of the inner space of the case 31 is too large, It is preferable that the case 31 has an internal space capable of appropriately accommodating the flow rate supplied from the inflow pipe 20.

The electrode unit 32 is mounted in the protective cover 32b with the electrode plate 32a having the negative electrode and the positive electrode superimposed thereon and is capable of disassembling the water of the water filled in the case 31 using the principle of underwater discharge Thereby producing a sterilizing water capable of having sterilizing power. That is, a plasma discharge is generated in water using an underwater discharge which makes water in the water plasma state underwater, and various anions (O-, O3-, OH-, HOCl and H2O2) Viruses, bacteria and the like.

At this time, as shown in the enlarged view of FIG. 2, the electrode plate 32a may be formed by stacking a plurality of electrode plates 32a in the protective cover 32b. If a plurality of electrode plates 32a are stacked, it is possible to more effectively induce underwater discharge and thus sterilization water generation .

The PCB substrate 33 is provided so as to be electrically connected to the electrode unit 32 by supplying power to the electrode unit 32 so that water discharged into the inner space of the case 31 can be discharged underwater. At this time, the circuit board 33 has a circuit in which different super-direct current discharge voltages are alternately applied to the electrode plates 32a so that plasma is generated between the electrode plates 32a having the cathodes and the anodes, .

A disinfecting water supply pipe 40 is connected to the outlet of the case 31 of the disinfection water generating module 30. The disinfecting water supply pipe 40 is connected to the inside of the dishwasher Which is provided in the sterilizing water generating module 30, to supply the sterilizing water generated by the sterilizing water generating module 30 to the sewage water. That is, when sterilization water generated in the sterilization water generating module 30 is supplied to the water supply pipe 10 through the sterilization water supply pipe 40, the washing water supplied into the dishwasher always contains a certain amount of sterilization water.

A sterilizing water inlet pipe 50 is connected to the sterilizing water supply pipe 40. The sterilizing water inlet pipe 50 is connected to the sterilizing water supply pipe 40 by means of the ultrasonic transducer 60, And serves to introduce a part of sterilized water into the ultrasonic vibrator 60 so as to be sprayed in a mist form.

The sterilizing water generated by the sterilizing water generating module 30 is supplied to the sterilizing water supply pipe 40 and the sterilizing water inlet pipe 50. In this case, The sterilized water supply pipe 40 and the sterilized water inflow pipe 50 can not be used separately because they are supplied to the inflow pipe 50 separately. Closing valves 41 and 51 for controlling whether or not the sterilized water flowing therethrough can be controlled, respectively.

The ultrasonic vibrator 60 is connected to the sterilizing water inlet pipe 50. The ultrasonic vibrator 60 serves to spray the sterilizing water introduced from the sterilizing water inlet pipe 50 into the dishwasher in a mist form A plurality of micropores are formed in the micro thin plate of the metal so that the sterilized water flowing in can be sprayed in an atomized state while being sucked in by the pressure operation by the up-and-down vibration.

When ultrasonic waves are transmitted through sterilizing water through the ultrasonic vibrator 60, numerous bubbles are generated and extinguished within the sterilizing water. At this time, each bubble becomes a state of high temperature and high pressure of several thousands of degrees Celsius, Cavitation effect by ultrasonic waves. Heat and pressure generated in the air bubbles by this cavitation is a major cause of removing contaminants from the object to be sterilized.

That is, when the sterilizing water is delivered to the object to be cleaned through the ultrasonic vibrator 60, fine waves are generated between the sterilizing water and the surface of the object to be cleaned, thereby suppressing the adsorption of contaminants on the surface of the object to be cleaned. Even in the case of adsorbed contaminants, the bubbles generated by the cavitation penetrate into an invisible fine gap formed in the contaminant and explode, and the explosive energy is advantageous in crushing contaminants into a small lump form .

[ ) Is installed.

Therefore, the construction and overall operation of the water supply system of the dishwasher having the dual sterilizing function according to another embodiment of the present invention is similar to the water supply system of the dishwasher having the double sterilization function according to the embodiment of the present invention, Only the transparent window 31a is formed in the case 31 and the reason why the LED lamp 33a is provided on the PCB substrate 33 will be described in detail in order to simplify the description .

As described above, the reason why the transparent window 31a is formed in the case 31 and the LED lamp 33a is installed in the PCB substrate 33 in the double water sterilizing water supply system according to the present invention is as follows. As shown in FIG. 5, when the sterilizing water is generated by the electrode unit 32, the user can visually confirm whether the water in the case 31 is discharged into the water, that is, bubbles are generated properly .
