Description

Apparatus for providing purified / ionized water by using cooling tank integrated with electrolyzer}

The present invention relates to an ionizer capable of providing purified water or ionized water according to a mode, and more particularly, to an electrolytic cell integrated water storage tank and a purified water and ionized water providing device having the same (or referred to as an 'ionizer').

In general, the ionizer is to allow the purified water to be ionized through the electrolytic cell to be used. The ionized water is electrolyzed through the electrolytic cell, so that the acidic water is alkaline and non-drinking water containing minerals of positive ions. Separate drain into water.

Ionizer has been the main function to produce alkaline water for drinking and cooking until recently, while on the other hand, it does not throw away the acidic water drained when the alkaline water is discharged from the electrolytic cell to the outside and adjusts the pH by skin type for skin care such as face washing and hand washing. It can be used or used as industrial washing water, and also to provide purified water separately from ionized water.

As shown in FIG. 1, the conventional ionizer includes a filter unit 11 for filtering raw water, a water storage tank 13 for cooling and storing purified water supplied from the filter unit 11, and the water storage tank. The electrolytic cell 15 which electrolyzes the cold water supplied from (13) and produces alkaline water and acidic water is provided.

However, in the conventional ionizer of FIG. 1, water stored in a connection pipe connecting the reservoir tank 13 and the electrolytic cell 15, that is, water exposed to room temperature, is transferred to the electrolytic cell 15 for a predetermined time after the user presses the water discharge button. Since it is supplied and electrolyzed and discharged, there is a problem that it takes a certain time to obtain the cold ion water of the desired temperature.

The present invention is to solve the above-mentioned conventional problems, the purpose is to increase the cooling effect of the final ionized water or purified water discharged from the electrolytic cell without a separate cooling facility, the electrolytic cell integrated storage tank and the purified water and ion water providing apparatus using the same To provide.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, like reference numerals are used to denote like elements throughout the drawings, even if they are shown in different drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

The principle of hydrolysis of water is so generalized that it has a history of about 100 years. In the early One Compartment Cell System, electrolyzed water was obtained using only two positive and negative electrodes in water with a small amount of electrolyte.

The pH of 1 tank electrolyzed water is weakly alkaline and contains a certain level of bactericidal power by containing sodium hypochlorite (NaClO). Recently, there has been a report of eliminating the red tide phenomenon by electrolyzing seawater through the one tank equipment (no electrolysis of seawater is needed), but the environmental risk has not been verified yet. Pollutant-free combustion materials have also been developed using a mixture of hydrogen and oxygen (Brown Gas) produced by electrolysis using potassium hydroxide (KOH) as an electrolyte. One tank equipment also has a number of limitations, including the corrosion of the surrounding environment and the immense generation of chlorine gas, which is caused by the phenomenon that the added electrolyte is not completely decomposed.

Since the development of the ion exchange membrane (Ion Exchange Membrane) with the purpose of generating the individual (two types) electrolytic water characterized by the two Compartment Cell System electrolyzer equipment as shown in Figure 2 was developed.

In the two tank type electrolyzer, a direct current voltage is applied to water to which a small amount of electrolyte (normal salt, etc.) is added, and ion exchange is performed through an ion exchange membrane (Separator) installed in the middle. On the +) side, various chlorine by-products (HCLOX) and chlorine gas (Cl2) are produced. Of these, chlorine and hypochlorite have been reported to have strong bactericidal power. In addition to the development of two tank equipment, the cleaning method using electrolyzed water in the general industry has been studied, but there are limitations in the generation of various kinds of chemical species and oxidation of the base material (the material to be cleaned).

3 is a view for explaining the basic structure and principle of the three tank electrolytic cell, Figure 3 (a) is a view for explaining the basic structure of the three tank electrolytic cell and the generation principle of the electrolysis water, Figure 3 (b ) Is a view for explaining the basic circulation system of the electrolyte and electrolyzed water in the three-bath electrolytic cell.

The three-chamber electrolyzer is an electrolysis device in the form of passing raw water directly to the electrolyzer as shown in FIG. The part indicated by the dotted line is a circulation system of the electrolyte for smoothly progressing the electrolysis. The electrolyte introduced into the intermediate chamber is electrolyzed and moved to both chambers, thereby producing acidic oxidation water and alkaline reduced water in both chambers. At this time, acid-oxidized water is generated on the anode side and alkaline-reduced water is generated on the cathode side.When NaCl is used as an electrolyte, acid-oxidized water has strong sterilizing power, and alkaline-reduced water has strong cleaning power and strong pH If you have a strong bactericidal power. In addition, the characteristics of the electrolyzed water generated according to the type of electrolyte added to the intermediate chamber is also different, the specification of the electrolytic system is also changed according to the type of electrolyte added.

One of the biggest differences from existing electrolysis techniques is that electrolytes such as salt are not added directly to raw water. Only electrolyte is supplied to the intermediate chamber, and when electrolysis is started, the electrolyte ions of the intermediate chamber move to the anode chamber or the cathode chamber as shown in FIG. 3A in proportion to the electrolytic current. That is, it is possible to move the minimum amount of ions required to reduce the concentration of ions in the electrolyzed water to a very small amount. Due to these characteristics, it is possible to generate high purity electrolyzed water having strong functionality even with a very small amount of electrolyte consumption. Another big difference is that it is possible to produce various kinds of electrolyzed water using various electrolytes in salt state.

The electrolytic cell 500 according to the present embodiment is installed in the storage tank 400 and is supplied from the storage tank 400 under the control of the controller 600 according to various modes set through the mode setting unit 700. To obtain the water as it is without the electrolysis, or to withdraw after electrolysis with acidic water and reduced water, for example, the above-described two tank electrolytic cell or three tank electrolytic cell may be applied.

Or it is to control the flow path that is obtained and withdrawn into the electrolytic cell 500 in addition to controlling the off.

The mode setting unit 700 according to the present embodiment is for setting various modes according to a user's selection. For example, the mode setting unit 700 may be a purified water mode for extracting purified water, a reduced water mode for extracting reduced water, or for extracting oxidized water. It can be configured to set the oxidation mode, the standard mode for simultaneously withdrawing the reduced and oxidized water.

As described above, according to the ionizer according to the embodiment of the present invention, since the electrolytic cell 500 is sufficiently immersed in the cold water stored in the storage tank 400, the electrolytic cell 500 does not have to be provided with a separate cooling facility. ) Is cooled by cold water stored in the storage tank 400, and thus purified water, alkaline reduced water, and / or acidic oxidation water discharged through the outlet of the electrolytic cell 500 is stored in the storage tank 400 even at the beginning of the extraction.
