The present invention relates to a dishwasher, and more particularly, to a dishwasher for sterilizing electrolytic water sterilized by electrolyzing water generated in the process of softening raw water flowing into a dishwasher.

In general, a dishwasher is used to make dishwashing easier, hygienic, and efficient. The dishwasher can be cleaned using a water spray washing method or a brush washing method using the washing water contained in the lower washing tank of the washing machine Allows you to wash dishes or spoons with food residue or foreign matter.

The dishwasher is provided with a dishwasher for washing the dishwasher. The dishwasher is provided with a dishwasher for washing the dishwasher. The dishwasher is provided with a dishwasher for dispensing washing water through a spray nozzle or a predetermined brush. .

Cleaning systems and cleaning methods using ultraviolet rays, ozone gas, and ultrasonic waves 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 sterilization efficiency is low with a method using only ultrasonic waves.

In order to improve the quality of the water supplied to the dishwasher and to improve the drying performance, a method of hygienically cleaning the training water is used by connecting the training water to the training device separately. However, There is a problem that the hard water generated in the regeneration step is discarded as it is.

In addition, even if the preliminary washing or the like is carried out using the water produced in the regeneration step, a large amount of rinse water is used, which causes a problem that the consumption of water is increased.

On the other hand, there is a method of increasing the sterilizing power by generating various oxidizing agents using electrolysis. In the case of electrolysis described above, it is necessary to supply water with a high total dissolved solids (TDS). In this case, There is a disadvantage that a high-cost electrode must be used.

In order to solve the above problems, it is an object of the present invention to provide an electrolytic water sterilizing dishwasher which increases the rate of generation of TDS by subjecting hard water generated in the process of softening the supplied raw water to electrolysis, .

In order to achieve the above object, the dishwasher for sterilizing electrolytic water according to the present invention is provided with a washing chamber having a shelf on which a subject to be washed is placed, a washing tank for storing the washing water sprayed by the subject, A main body having a machine room in which a number of parts are housed so as to supply the washing water to the washing chamber; a water softening module for supplying soft water or hard water generated in the process of softening the raw water supplied from the water supply hole to the washing tank; And an electrolytic water generating module capable of increasing the sterilizing power by subjecting the hard water provided from the training module to an electrolysis process.

Here, the water softening module includes a water softening tank having an ion exchange resin in which regenerated water is regenerated by supplying regeneration water from the regeneration passage storing the regeneration liquid, and the regenerated water having increased water- And may be supplied to the washing tank after being electrolyzed by the electrolytic water generating module.

In addition, the training module may be provided with a first switching valve capable of supplying raw water for regeneration to the regeneration tank or changing the flow path so as to supply raw water for rinsing the regeneration tank.

In addition, the training module may be provided with a second switching valve capable of supplying raw water directly from the water receiving port to the electrolytic water generating module or changing the flow path so as to supply the raw water to the water softener.

Also, the raw water supplied to the electrolytic water generation module by the second switching valve through the regeneration tank or the water softener can be introduced into the washing tank by the first switching valve, and the washing can proceed.

In addition, the raw water supplied to the soft water tank by the second switching valve is ion-exchanged with the ion resin therein, and then supplied to the washing tank to rinse the laundry to be washed.

The electrolytic water sterilizing dishwasher of the present invention described above has an effect of enhancing its utility as washing water by using regenerated water which can be discarded into wastewater from a training module instead of using conventional tap water as it is to increase washing power for washing dishes and the like . Further, the amount of dissolved solids remaining in the washing water is increased by increasing the amount of the remaining solids remaining so that the sterilizing function can be increased.

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, an electrolytic sterilizing dishwasher 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 illustrating the operation of the electrolytic water sterilizing dishwasher according to the present invention, FIG. 2 is a schematic view showing the structure of the electrolytic water sterilizing dishwasher according to the present invention, and FIG. As viewed from above.

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

The electrolytic water sterilizing dishwasher 100 according to the present invention will be described with reference to FIGS. 1 to 3. FIG. The electrolytic water sterilizing dishwasher 100 includes a main body 101 having a washing tub 130, a water inlet 112 for controlling raw water to be supplied into the main body 101, a water softener module 112 connected to the water inlet 112 140 and an electrolytic water generation module 150 supplied with soft water or regenerated water from the water softener module 140.

The main body 101 is provided with a washing chamber 110 for accommodating dishes in a rack (not shown) provided therein and for washing dishes stored in water sprayed through a spraying gun (not shown) or the like, A machine room 120 in which a number of parts are installed to supply high-pressure water is provided. The water stored in the washing tub 130 by the operation of a pump or the like installed in the machine room 120 as a space for storing the water introduced from the water softener module 140 or the electrolytic water sterilizing module 150 is injected for washing.

Referring to FIG. 1, the process mainly focuses on the process in which raw water flows through the soft water module 140 to soften or soften.

First, the raw water is supplied from the outside to the water receiver 112 through the raw water passage 102. The water outlet 112 may be disposed inside the dishwasher 100 or may be disposed outside. The water supply port 112 supplies raw water to the first and second switching valves 143 and 144 in the water softening module 140. The first flow path 103a is connected to the first switching valve 144 and the second flow path 103b Is connected to the second switching valve 143. The first flow path 103a has a concept of a supplementary feeding path, and the first switching valve 144 continuously supplies raw water. The second switching valve 143 receives the raw water from the second flow path 103b and distributes the raw water to the water tub 141 or the electrolytic water generation module 150.

The training module 140 includes a training tube 141 and a regeneration tube 142 therein. The regeneration tank 142 is filled with salt for supplying regeneration water to regenerate the ionic resin when the performance of the ionic resin is lowered.

Before describing the water circulation relationship in the training module 140, the connection flow path between the respective devices is defined as follows.

The raw water supply flow path from the second switching valve 143 to the water softening tank 141 is referred to as A flow path and the soft water supply flow path from the water softening tank 141 to the washing tank 130 in the main body 101 is referred to as B flow path, The regeneration flow path from the regeneration tank 142 to the regeneration tank 142 is referred to as a C flow path while the drain flow path from the water tub 141 to the electrolytic water generation module 150 is referred to as a D flow path, And the electrolytic water supply flow from the electrolytic water generation module 150 to the cleaning tank 130 to the electrolytic water generation module 150 is referred to as the G flow, And a regeneration water supply passage for supplying the regeneration water from the regeneration cylinder 142 to the water softeners 141 are respectively defined by H channels.

The first switch valve 144 is connected to the water softener 141 and the regenerator 142 via the E and C flow paths, respectively, to regulate the flow of the regeneration or rinsing process. That is, when the performance of the ion exchange resin in the water tub 141 deteriorates due to continuous use of the ion exchange resin, the regeneration water containing the Na + Thereby allowing the accumulation of Ca2 + and Mg2 + to be substituted.

After the regeneration process, the raw water is supplied from the first switch valve 144 directly to the water softener 141 in order to rinse Na + remaining in the water softener 141 outside the ion exchange resin 141 .

The second switching valve 143 is connected to the water softener 141 and the electrolytic water generating module 150 via the A and F flow paths, respectively. The raw water supplied through the A channel is subjected to a soft water process in which the hardness component is removed from the water tub 141. The treated water flows into the washing tub 130 in the main body 101 through the B flow path. The raw water supplied through the F channel is electrolyzed in the electrolytic water generating module 150 and converted into electrolytic water, and then flows into the washing tank 130 through the G channel.

Hereinafter, a process of making electrolytic water using raw water or hard water is examined.

The electrolytic water sterilizing dishwasher 100 according to the present invention is used for washing water in a state in which regenerated water or rinsed water discharged during a training process is electrolyzed to lower the use rate of the detergent and improve the effect of washing.

In general, raw water introduced from outside contains chlorine, which is usually used for disinfection. Electrolyzed water is ionized by hydrogen atoms and oxygen atoms, and ionized oxygen atoms and chlorine are combined and oxidized mixed substances Chlorine (ClO < " >). The chlorine monoxide generated in this manner has a property of easily adsorbing other components, and thereby, by sucking harmful bacteria of the tableware housed in the washing chamber 110, sterilizing and cleaning can be performed.

In the electrolytic water generating module 150 of the present invention, it is necessary to supply water having a high TDS (dissolved oxygen amount) for generating electrolytic water. Therefore, the water containing various ions such as Cl-, Ca2 + and Mg2 + Can be utilized. The hard water is supplied from the water tub 141 to the electrolytic water generating module 150 via the D channel. Since the water is regenerated or rinsed, the dissolved ions are present in much larger amounts than the ordinary tap water.

Water electrolyzed in the electrolytic water generating module 150 exhibits a sterilizing effect. The electrolytic sterilization is a technique for sterilizing or extinguishing microorganisms remaining in water by allowing water to pass between electrodes having different polarities. In the treated water, an oxidizing mixed material, such as chlorine (Cl 2), hypochlorite ion (OCl-) and other sterilizing ions and free radicals, is produced which has sterilizing action. The various oxidizing agents, such as hypochlorous acid, chlorine, chlorine dioxide and other chlorinated oxidants, are the most effective sterilizing agents used for hygiene purposes in household or industrial products.

The strong oxidative potential of such oxidant molecules has been applied in various fields including disinfection and sterilization, and a detailed description of the disinfection and sterilization process and effect is omitted.

On the other hand, electrolytic water can be produced using raw water itself as well as the regenerated or rinsed water. F water can be supplied directly to the electrolytic water generating module 150. In this case, sterilizing effect is also obtained because ions such as Cl- remain in the raw water.

In summary, it is preferable that the electrolytic water generating module 150 is supplied with regenerated water enriched with floating ions while being regenerated, but there is a certain part of the water cost after the rinsing process. In addition, since there is a floating water ion in the raw water which has not undergone any process, it can be supplied to the electrolytic water because there is a sterilizing effect.

Hereinafter, the operation of the electrolytic water sterilizing dishwasher 100 according to the present invention will be briefly described with reference to FIGS. 1 to 3. FIG.

The raw water received from the outside via the water receiving hole 112 flows into the water softening module 140 via the distribution channel 103. The regenerated or rinsed water in the training module 140 is transferred to the electrolytic water generation module 150 through the water supply channel 104 (D channel or F channel), and is converted into electrolytic water and supplied to the cleaning bath 130. The washing water supplied to the washing tub 130 is allowed to perform the washing action on the tableware loaded in the washing chamber 110 by the operation of the machine room 120.

After the above-mentioned cleaning action, soft water can be supplied to wash off the ingredients in the dishes. The raw water that has flowed into the water softening module 140 through the distribution channel 103 is converted into ionic resin and supplied to the washing tub 130 through the soft water supply channel 106 and the B flow channel. The water treated afterwards helps to improve the drying by bringing the surface condition of the washed material to drying.

As described above, the present invention intends to improve the efficiency of washing water by using regenerated water that can be discarded into wastewater from the water softening module, instead of using the conventional tap water as it is to increase washing power for washing dishes and the like. That is, by increasing the TDS, the amount of dissolved ions remaining in the washing water is increased, thereby increasing the sterilizing function. The above-described method has an advantage in that the cost of using the electrode and the generation time of the electrolytic water are relatively reduced compared with the conventional method.

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.
