Description

[0001] Dishwasher using Electrode Sterilization Module [

The present invention relates to a dishwasher, and more particularly, to a dishwasher for supplying sanitary water to a dishwasher, And more particularly to a dishwasher using an electrode sterilizing module.

In general, a dishwasher is used to facilitate the cleaning of a tableware more easily, sanitarily, and efficiently, and may be performed by using a washing water contained in a bottom washing tank of the washing machine or a water spray washing method using a nozzle from the top Use a brush cleaning method to wash dishes or spoons that have food residue or foreign matter.

The dishwasher is provided with a dishwasher for washing the dishwasher, a dishwasher for dishwashing the dishwasher, a washing machine for washing the dishwasher, .

Cleaning systems and cleaning methods using ultraviolet rays, ozone gas, ultrasonic waves, and the like have been proposed so that fruits and vegetables can be cleaned without using a conventional detergent by a cleaning method. However, the above-mentioned apparatuses and methods are complicated in technology and expensive to install, so that they are not practically practical.

In addition, the method using ultraviolet rays is suitable for sterilization of air, but it is not suitable for sterilizing water. In the method using ozone gas, ozone is harmful to human body, so the amount of ozone to be used should be appropriately controlled. And there is a disadvantage in that the sterilization efficiency is low with a method using only ultrasonic waves.

On the other hand, a sterilization system using an electrode is generally used. In general, a sterilization system for controlling bacteria in water by making platinum on a conductive substrate to generate electricity by applying electricity, or using a diaphragm to lower PH . However, in many cases, the sterilization system using the above-mentioned electrode is not applied in practice because the conventional sterilization system has a problem of impurities in sterilization power and operability, and sterilization is not completely performed.

In the sterilization system using the platinum electrode, there is a problem in high unit cost of platinum, power waste due to high voltage operation, and antibacterial power.

In order to solve the above problems, an object of the present invention is to provide an electrode sterilizing module for sterilizing water to be cleaned by passing sterilizing water at a high concentration by passing an electrode sterilizing module over raw water supplied from a water inlet, And an object of the present invention is to provide a dishwasher using the same.

In order to accomplish the above object, the dishwasher using the electrode sterilizing module according to the present invention comprises a main body on which the object to be cleaned is placed, a conductive mother body, and a metal catalyst material surrounding the conductive mother body, A sterilizing device provided with an electrode sterilizing module alternately connected to an electric wire of a positive electrode or a negative electrode to supply sterilized water to the main body and a regulating valve interrupting the flow of the sterilized water between the main body and the sterilizing device .

Here, the electrode sterilizing modules may be arranged in a line or arranged in a lattice shape while maintaining a constant spacing distance.

The control valve includes a raw water flow passage for receiving raw water from the water supply valve, a sterilizing water flow passage for receiving the sterilization water from the sterilization device, and a training water passage connected to the training module for providing raw water from the water supply valve, And the control valve is connected to the main water passage, the sterilizing oil passage, and the water supply passage in accordance with the progress of the washing in the main body, The soft water channel can be selectively opened and closed and supplied to the wash water supply channel.

Preferably, the metal catalyst material may be iridium (Ir) or ruthenium (Ru).

Preferably, the concentration analyzer is connected to the control unit at a point where the sterilizing water is discharged from the sterilizer. If the sterilizing water concentration in the concentration analyzer does not fall within a predetermined reference value range, The concentration of the sterilization water can be controlled by controlling the power supply unit.

The dishwasher using the electrode sterilizing module of the present invention described above can be constructed in such a manner that sterilizing water can be sterilized at all times and supplied to the washing tub, so that sterilized water can be smoothly supplied even in the amount of fluid washing. The durability and power consumption of the electrode can be minimized and the performance can be realized in a small size regardless of the high flow rate.

In addition, by using an electrode sterilizing module coated with a platinum group catalyst, a high concentration of sterilization water can be generated even in the absence of a diaphragm in the container, thereby enabling a high level of safe sterilization.

These and other objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the accompanying drawings. Hereinafter, a dishwasher using an electrode sterilizing module according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a conceptual view for explaining an overall structure of a dishwasher using the electrode sterilizing module according to the present invention, and FIG. 2 is a diagram showing a connection relationship between components and a control unit applied to the present invention.

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

1 and 2, a structure of a dishwasher using the electrode sterilizing module according to the present invention will be described. The dishwasher according to the present invention includes a washing cylinder 160 for washing the object to be washed, a sterilizing apparatus 100 for supplying sterilizing water to the washing cylinder 160, a cleaning cylinder 160 and a sterilizing apparatus 100 And a water supply module 150 separately connected to the upper end of the flow path switching valve 140. The flow control valve 140 is connected to the flow control valve 140,

The flow path switching valve 140 includes a raw water flow passage 148 for receiving raw water from the water supply valve 10, a sterilizing water flow passage 146 for receiving sterilizing water from the sterilizing device 100, A water supply channel 144 connected to the water softening module 150 for providing the water in a softened state and a wash water supply channel 142 connected to the wash tub 160,

The flow path switching valve 140 receives an electrical signal from the control unit 180 and controls the flow path switching valve 140 in accordance with the progress of the washing in the washing tub 160, So that the cleaning water can be supplied to the cleaning water supply passage 142.

First, the sterilizing apparatus 100 includes a main body 101 of a container shape and at least one or more electrode sterilizing modules 110 mounted in the main body 101. The main body 101 is connected to an inlet flow passage 134 at one side thereof so as to be able to communicate with the inside of the main body 101 and to the outlet side flow passage 146 at the other side thereof.

Control valves 134a and 146a are provided in the input and output paths 134 and 146 to appropriately control the supply of raw water flowing through the flow paths 134 and 146. [ The raw water can be either ordinary tap water or water having a high total dissolved solids (TDS) ratio. In the present invention, the oxidizing mixed material is generated in the raw water through the electrocatalytic reaction, thereby sterilizing or destroying microorganisms or bacteria remaining in the raw water. The raw water supplied into the main body 101 is electrochemically reacted The sterilizing water 102 is changed to sterilization action.

The control unit 180 may automatically control the sterilization progress time and the degree of contamination in the main body 101 and may open and close the control valves 134a and 146a, So that the state of the sterilizing water 102 in the main body 101 is maintained in an appropriate state for sterilization.

The electrode sterilizing module 110 may be mounted on a mounting means (not shown) in the main body 101. The plurality of electrode sterilizing modules 110 may be arranged in a line or in a lattice shape while maintaining a predetermined gap therebetween. It goes without saying that the above arrangement may be varied depending on the volume, shape or use of the body 101.

The electrode sterilizing module 110 is electrically connected to the power supply unit 120 outside the main body 101 and may be configured to alternately meet the positive electrode or the negative electrode. That is, a plurality of electrode sterilizing modules 110 are arranged and each of the electrode sterilizing modules 110 is connected to the electric wires 112 and 114 connected to the cathode or the anode in order. The electrode sterilizing modules 110 may be arranged in a line or arranged in a lattice shape while maintaining a constant separation distance.

 The electrode sterilizing module 110 minimizes the gap between the cathode sterilizing module 110a and the anode sterilizing module 110b so that a sufficient amount of oxidizable mixture can be produced even at a low voltage, And the contamination degree of the object requiring sterilization. The electrode sterilizing module 110 may be configured to protrude somewhat from the main body 101. This allows an operator to connect the electric lines 112 and 114 to the electrode sterilizing module 110 from the power source 120 without difficulty .

The electrode sterilizing module 110 consists of a conductive matrix 116 and a metal catalyst material 115 surrounding the conductive matrix 116. After the conductive matrix 116 is cleaned with a cleaning material such as oxalic acid, the metal catalyst material 115 dissolved in a certain solvent is coated on the conductive matrix 116 and then heated and sintered in a high-temperature drying furnace.

Since the conductive matrix 116 must be directly connected to the power source 120, a material having a low electrical resistance is preferable. In general, it may be any one of titanium (Ti), iron (Fe), nickel (Ni), and stainless steel (SUS). Titanium (Ti) may be preferably used.

The metal catalyst material 115 used in the electrode sterilizing module 110 may be any one of ruthenium Ru, tin Sn, iridium Ir, praseodymium Pr, or lead Pb , Preferably ruthenium (Ru) or iridium (Ir) may be used.

The process of producing the sterilized water will be described using ruthenium as a representative. Ruthenium is a kind of platinum group. When ruthenium is baked at a high temperature in a state coated with the conductive matrix 116, the ruthenium oxide is converted to RuOx and remains on the conductive mother surface.

Ruthenium oxide is a chlorine ion (Cl ^-) in the electrolytic solution is a catalytic role in changing to a chlorine gas (Cl _2). The chlorine gas generated here is instantly dissolved in water by solubility to form residual chlorine (OCl ^- , HOCl ^- etc.). Residual chlorine (OCl ^- , HOCl ^- ) is a typical disinfectant and is generally used for disinfection of tap water.

Iridium (Ir) has a lower electrolysis efficiency than ruthenium (Ru), but has the advantages of lower cost and greater strength than ruthenium (Ru).

The effect of using ruthenium in the present invention will be described based on concrete data. First, the experiment is performed by keeping the same parameters as those applied to the experiment, such as the size of the sterilizing module 110, the distance between the sterilizing modules 110, and the intensity of the applied voltage.

As a result of the experiment conducted by applying a voltage of 12V in the above state, the platinum (Pt) electrode is 0.03 ppm, iridium (Ir) is 0.05 ppm and ruthenium (Ru) is about 0.1 ppm based on the residual chlorine concentration , Showing that ruthenium is most effective in increasing residual chlorine. As shown in the experimental data, iridium (Ir) and ruthenium (Ru) are more efficient than conventional platinum.

The sterilization apparatus 100 may be disposed at a front end of the cleaning cylinder 160 and may be provided in a stationary manner so as to supply sterilized water at all times. The concept of congestion is a system that creates a sterilized water that is electrolyzed by putting raw water in a certain container and adding an electrode. In the present invention, it is preferable to use a static type. However, the static type has advantages that the electrode is not required to be large compared to the water type, the power consumption is small, and the cost is small. In addition, since the concept is to operate in the raw water flowing through the water flow, the gap between all the electrodes is small enough to operate properly. In contrast, the static type is advantageous in terms of the gap utilization because the gap is relatively wider than the water flow type. In addition, since the sterilizing water concentration of sterilized water can be controlled with time, it is advantageous in that it can be configured very simply compared with other control methods.

Here, the filter device 130 may be installed at the front end of the sterilizing device 100 for scale control such as impurities. The filter device 130 may perform a function of adsorbing and removing unnecessary ions for the purpose of improving the sterilizing function in the sterilizing device 100.

The concentration analyzer 170 is provided so as to be connected to the control unit 180 at a point where the sterilizing water is discharged from the sterilizer 100 so that the sterilizing water concentration in the concentration analyzer 170 falls within a predetermined reference value range The sterilization module 110 can be controlled by controlling the power supply unit 120 that supplies power to the sterilization module 110. In other words, if the control unit 180 does not fall within the allowable range of sterilization water preset by the control unit 180, the electrolytic performance of the sterilization module 110 is controlled by controlling the current and voltage applied to the sterilization module 110 from the power supply unit 120 .

The soft water module 150 has a built-in ionic resin therein to soften the hard water supplied from the water supply valve 10, thereby providing a convenient hygienic and clean finish.

A washing tub 160 is connected to the rear end of the sterilizing apparatus 100 for receiving sterilized water from the sterilizing apparatus 100 and washing the sterilized water. The cleaning cylinder 160 includes a washing chamber 169 for storing dishes in a shelf 168 provided therein and for washing dishes stored in water supplied from the injection nozzle 164 through a spraying arm 163, 169 to supply high-pressure water. The mechanical chamber 161 and the washing chamber 169 can be isolated by a constant diaphragm 162. The discharge water storage container 167 is located outside the washing chamber 169 so that the washed water can be collected. The discharge water containing the washing water 165 is supplied to the lower portion of the washing chamber 169, (166).

Hereinafter, the operation of the dishwasher using the electrode sterilizing module according to the present invention will be described with reference to FIGS. 1 and 2. FIG.

First, the raw water supplied from the water supply valve 10 may be composed of a four-way valve. The raw water flowing into the water supply valve 10 from the water pipe through the first flow path 12 is sterilized through the second flow path 132 To the device 100, to the soft water module 150 via the third flow path 152, and to the fourth flow path 148 (raw water flow path).

The raw water from the water supply valve 10 is always kept in a sterilized water state in the sterilizing apparatus 100 and the water softening unit 150 is also ready to be supplied with a certain amount of soft water immediately.

The flow path switching valve 140 selectively opens and closes the flow paths 144, 146, and 148 in response to an instruction from the control unit 180 when the object to be cleaned is loaded on the cleaning cylinder 160 and the user operates the power button. For example, the washing process will be described as follows. First, the raw water flow path 148 is opened to supply raw water directly to the washing tub 160 to perform primary washing.

First, after washing with the washing water in which the detergent is dissolved by using the primary washing, the washing water on the raw water passage 148 is continuously supplied to wash the detergent, thereby performing the first and second rinsing. The sterilization water from the sterilization apparatus 100 or the soft water from the soft water module 150 is then used to cause the final rinse to proceed. In the final rinsing step, it is preferable to use a high-temperature rinsing water to prevent localization in a subsequent drying process and also to produce a sterilizing effect.

On the other hand, if it is desired to carry out sanitary cleaning from the beginning according to the user's intention, it is possible to use only the supply water supplied from the sterilizing device 100 or the training module 150 without using the primary cleaning through the raw water channel 148 . In this case, by automatically or manually controlling the flow path switching valve 140 or the water supply valve 10, the process of cleaning the user can be selectively controlled.

In the process of washing, the controller 180 displays the cleaning step on the display unit 190 so that the user can see the cleaning step at a glance.

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
