Description

Ionized Water Generator {ION WATER GENERATING DEVICE}

The present invention relates to a cold ionizer, and more particularly, to a cold ionizer for providing cold ionized water ionized in an electrolytic cell.

In general, an ionizer is a device that provides alkaline or acidic water when a user's request is obtained by separating purified water or raw water from an electrolytic cell into acidic and alkaline water through a filter unit, and may be used with a cooling or heating function.

1 is a schematic configuration diagram showing an example of a conventional ionizer.

As shown in FIG. 1, the conventional ionizer 40 includes a plurality of filters 11, 12, 13, and 14, and a filter unit 10 for filtering and purifying tap water, and the filter unit 10. An electrolytic cell 20 for generating acidic water and alkaline water by electrically decomposing purified water from the purified water, a storage tank 30 for storing alkaline water generated in the electrolytic cell 20, and stored in the storage tank 30. A takeout cock 32 for taking in alkaline water is provided.

As shown in FIG. 1, the filter unit 10 may include, for example, a precipitation filter 11 that filters particles of purified water from the raw water supply unit 16, and removes chlorine components and odors from the purified water. To remove the odor contained in the precarbon filter 12, the membrane filter 13 for removing the fine particles remaining in the raw water passed through the precarbon filter 12, and the water passed through the membrane filter 13 It may be configured as a post carbon filter 14, and may further include a pressurizing pump 15 for moving the supplied raw water to a predetermined pressure.

In addition, the storage tank 30 may include a tank for storing cold water and / or hot water as well as a normal temperature tank for storing normal temperature water, as well as a separate cooling and / or heating function.

As such, the purified water filtered by the filter unit 10 is ionized through the electrolytic cell 20, wherein the acidic water is stored in the acidic water storage tank (not shown) through the acidic water discharge pipe 22 to meet the user's request. Used or discharged to the outside.

In addition, the alkaline water is stored in the storage tank 30 through the connecting pipe 21 is provided to the user through the discharge pipe 31 and the discharge coke 32 when the user's request.

The ionizer 40 described above is configured in the order of the filter unit 10 → the electrolytic bath 20 → the storage tank (cold water tank) 30 in view of the ionized water treatment step. Therefore, the alkaline water generated through the electrolytic cell 20 is stored in the storage tank (cold water tank) 30 until the user withdraws.

Therefore, the above-described ionizer 40 has an advantage of being effective in maintaining the temperature of cold ionized water.

However, when the alkaline water stays in the storage tank 30 for a long time, the pH concentration gradually decreases as the ionic component of the alkaline water disappears over time. Furthermore, when stored in the storage tank 30 made of a metal material, there is a problem in that the ionic component quickly disappears because the ionic component is combined with the metal to return to the stabilized state.

In addition, the alkaline water has a problem that the scale is formed in the storage tank 30 because the calcium component of the ionized water is entangled with crystals over time, and the alkaline water stored in the storage tank 30 is extracted, so that no immediate pH change is made. There is a problem.

Accordingly, the ionized water treatment step is arranged in the order of filter part → storage tank (cold water tank) → electrolytic bath, and the purified water is stored at low temperature through the filter part, and when the user's request is made, the cold water tank ionizes the purified water in the cold water tank. Was developed.

That is, as shown in Figure 2, the cold ion water heater 80 according to the prior art is a cold water tank for cooling and storing the filter unit 10 consisting of a plurality of filters, and purified water purified by the filter unit 10 50, a pump 55 for supplying purified water cooled in the cold water tank 50 to the electrolytic cell 60, and an electrolytic cell 60 installed after the pump 55 to generate acidic and alkaline water. Consists of.

However, the above-described ionizer 80 must be provided with a power device such as a pump 55 for forming a negative pressure in the electrolytic cell 60, so not only the movement distance of the cold water is extended but also the cold water by the operation of the pump 55. There is a problem that it is difficult to supply a uniform temperature of cold water to increase the temperature.

In addition, there are various components 55 and 60 after the cold water tank 50, in particular, water remains inside the pump 55 and the electrolytic cell 55, and thus the temperature of the cold ionized water is increased during initial intake. The noise is generated by the operation of the pump 55, and various problems necessary for the pump 55 and its connection are taken, resulting in a problem of cost increase.

Accordingly, there has been a need for a cold ionizer to solve the problems with the ionizer of FIGS. 1 and 2 to provide cold ionized water having a uniform pH concentration and a constant temperature.

In addition, in recent years, a configuration such as the cold water tank 50 has become a problem of contamination, a direct draw configuration has been proposed to take water directly without storing the purified water. 3 shows an example of such a direct configuration.

As shown in FIG. 3, the purified water passing through the filter unit 10 is branched into the upper constant water supply path and the cold constant water supply path by the flow path switching valve 72. In the case of the constant water, the extraction coke 78 is extracted through the valve 77. In the case of the cold water, the cold water supply passage passes through the cooling unit 70, and after cooling, the extraction coke 76 is passed through the valve 75. Extracted).

The cooling unit 70 is filled with a refrigerant 74, the evaporator 73 for cooling the refrigerant is configured in such a way that surrounds the cooling unit 70, the cold water supply pipe heat exchanges between the cold refrigerant to create a cold water Losing composition.

In such a direct-type structure, since the cold water tank 50 does not exist separately, there is a problem that cold ionized water cannot be extracted even if an electrolytic cell is installed.

The present invention is to solve the above problems, and an object of the present invention is to provide a cold water ionizer with a uniform pH concentration.

In addition, an object of the present invention is to provide cold ionized water having a sufficiently low temperature of the initial cold ionized water in a direct extraction method without a separate storage tank.

The present invention provides the following configuration to achieve the above object.

In the present invention, the cooling unit may be purified water, and the electrolytic cell may be an ionized water generating device including a purified water supply unit through which the purified water is supplied and a cold water supply unit communicating with the cooling unit.

In the present invention, the electrode of the electrolytic cell is preferably disposed in the direction of gravity.

In addition, in the present invention, the electrolytic cell may be disposed on the side of the cooling unit outside or inside the cooling unit.

In the present invention, the cooling unit may be configured by winding an evaporator.

However, in the case of the ionized water supply pipe 126, the phase ionized water also passes, and thus may be formed in a straight line such that the heat exchange area and the residence time are not long as in the cooling passage 124.

In the case of ordinary ionized water, the purified water passing through the normal ionized water supply pipe 121 is directly supplied to the electrolytic cell 150, and the electrolytic cell 150 ionizes the constant water introduced in the same manner as the cold ionized water, so that the alkaline water is supplied to the ionized water supply pipe 126.
