Description

Water purifier with electrolytic cell {WATER PURIFIER EQUIPPED IONIZER}

The present invention relates to a water purifier having an electrolytic cell, and more specifically, to filter out impurities or odors that are harmful to the human body through a multi-stage filter, and to generate silver (Ag) nano ions by electrolysis. The present invention relates to a water purifier equipped with an electrolytic cell that supplies raw water to eradicate bacteria and suppress reproduction, and supply active hydrogen to raw water to discharge active oxygen from the inside of the body when consumed.

In addition, the components constituting the electrolytic cell is composed of a structure assembled with each other, the wires supplying power to the electrode plate is placed outside the electrolytic cell, even if the raw water is filled in the electrolytic cell, the electrolytic cell is connected directly to the water supply pipe. It is about water purifier which can be.

An electrolytic cell is provided with a constant current applied to the anode and cathode plates of the electrolytic cell to ensure stable electrolysis and to periodically change the polarity of the power applied to the two electrode plates so that the silver (Ag) component of one of the electrode plates does not disappear first. It is about one water purifier.

As is well known, tap water caused by by-products caused by environmental pollution and pollution is very low in purity. Recently, the importance of water purifier and bottled water is rapidly increasing due to the importance of water.

Along with cooking, water used for showering, massage, and medical treatment also has a direct effect on the skin upon contact with the skin, which can cause skin diseases depending on the ingredients contained in the water. Therefore, the importance of water is increasing.

Due to the increased interest in health, water purifiers that introduce ultraviolet lamps for sterilization as well as filters for removing impurities or odors have been released.

Ultraviolet lamps have excellent instantaneous sterilizing power, but since sterilizing water is not present in the sterilizing water stored and supplied to the reservoir after sterilization, they are exposed to general bacteria and biological contamination. That is, bacteria and microorganisms exist in the storage tank due to the presence in the atmosphere or the surrounding environment, or water in the storage tank is recontaminated by untreated microorganisms through an ultraviolet sterilizer, and especially during the night time without the use of a water purifier. Regrowth of bacteria occurs.

In order to supplement the problems of the ultraviolet lamp system, a water purifier for introducing functionality into electrolyzer has been recently proposed.

Examples of the water purifier provided with such an electrolytic cell include the registration room No. 0392681 "electrolytic water purification system", the registration room No. 0412166 "water purifier attached ionizer", and the like.

As described in the drawings of the specification, the practical use of the electrolytic cell has a large volume (corresponding to the size of the filter), and has a structure in which the longitudinal direction of the electrolytic cell is installed parallel to the gravity direction. In other words, a large space for installation must be secured separately, and the installation method is also limited.

In addition, in order to discharge an appropriate level of ions according to the capacity of the water purifier, it is necessary to adjust the quantity of the electrode plate. In the registration room, the quantity of the electrode plate cannot be adjusted. Should be increased.

In addition, in the conventional electrolytic cell in which electrolysis is performed, a positive electrode plate and a negative electrode plate are disposed therein, and power is supplied to both electrode plates so that electrolysis is performed to supply silver ions to raw water.

Since the same polarity power is continuously applied to the positive electrode plate and the negative electrode plate, the silver of the positive electrode plate gradually disappears, but the silver of the negative electrode plate hardly changes or increases. This results in a short period of time for the continuous production of silver ions with the two pole plates, and the replacement of the two pole plates together, even though the negative plate continues to be used, is a waste of resources.

The present invention has been made in order to solve the above problems, it is not a problem even if the raw water in the raw water receiving chamber of the electrolytic cell is filled with a small amount of raw water receiving chamber, it is possible to directly connect the electrolytic cell to the water supply pipe It aims at providing the provided water purifier.

In addition, since the components of the electrolytic cell are stacked and assembled, the number of electrode plates can be increased according to the capacity of the water purifier, and thus, an object of the present invention is to provide an economical water purifier without requiring additional electrolytic cell installation.

In addition, the electrolytic cell is small in size (miniaturized) and there is no restriction in that it must be installed horizontally or vertically, and an object of the present invention is to provide a water purifier that can utilize the inner space of the water purifier main body as an electrolytic cell installation space.

In addition, by supplying a constant current to the positive and negative plates of the electrolytic cell to ensure a stable electrolysis, and by periodically changing the polarity of the power applied to the two electrode plates, the electrolytic cell is provided for a longer time to supply ions and reduce unnecessary resource waste It is an object to provide a water purifier.

The replacement time can be not only visually informed via lamps, but also by voice. Of course, this requires a speaker.

The circuit part 200 supplies a stable and constant power of the constant current to the electrode plate 110 of the electrolytic cell 100 by the constant current control method, and periodically changes the polarity of the power supplied to the electrode plate 110 for electrolysis. This prevents the metal plated on the specific electrode plate 110 from being released and dissipated faster than the metal plated on the other electrode plate 110. Of course, the circuit unit 200 may control the power supplied to the electrolytic cell by the constant voltage control method.

The circuit unit 200 receives a signal from a water quantity sensor such as a bure provided in the reservoir, and when the amount of raw water filled in the reservoir decreases, the solenoid valve is opened and at the same time, power is supplied to the electrolytic cell to store the raw water in which silver ions are dissolved. Save it to When the raw water is filled in the electrolyzer, the solenoid valve is closed and the power supply to the electrolyzer is also cut off.

The constant current control method of the circuit part is more complicated than the constant voltage control method, but it is less influenced by external factors, which enables stable power supply, prevents overheating, and affects the temperature of raw water (generally chemical reaction (electrolysis)). Is influenced by the temperature of the water) and has the advantage of generating a constant concentration of ions. The circuit unit may control the concentration of silver ions generated by the electrode plate by adjusting the intensity of the constant current supplied to the electrolytic cell.

The circuit unit 200 will be described later.

The filter is installed on a pipeline connecting the water supply pipe and the water reservoir to filter not only particulates (fine dust, suspended matter, etc.) contained in the raw water flowing through the water supply pipe but also certain harmful components.

And a quantity detection sensor (not shown) such as a bee for detecting the quantity of raw water is provided.

The electrolytic cell 100 electrolyzes the electrode plate 110 to generate silver (Ag) ions and elute them in raw water. The ions produced by electrolysis destroy bacteria and inhibit reproduction in raw water. In particular, silver (Ag) nano ions are known to be excellent in this antibacterial function because they act to stop the reproduction of enzymes involved in the metabolism of bacteria.

Hereinafter, the configuration of the electrolytic cell will be described in more detail with reference to an exploded perspective view of the electrolytic cell 100 shown in FIG. 3.

The electrolyzer is usually installed on a pipe connecting the water supply pipe and the reservoir, but may be installed between the reservoir and the cold and hot water discharge pipe, and therefore, the present invention is not limited to being installed on the pipe connecting the water supply pipe and the reservoir.

As shown in Figure 3, the electrolytic cell 100 of the present invention is assembled electrode plate 110, the frame member 120, the upper cover 130, lower cover 140, packing 150, contact blocking It is made, including the member 160,

The lower cover 140, the plurality of edge members 120 and the upper cover 130 to which the electrode plate 110 is coupled are sequentially stacked to form a raw water receiving chamber in which raw water is accommodated, and between the electrode plates 110. The contact blocking member 160 is disposed therebetween.

The electrode plate 110 may be in the form of silver plated on the surface of pure silver (Ag) or a conductive material.

In addition, a predetermined portion of the electrode plate 110 has a protrusion 111 forcibly inserted into and coupled to the through hole 121 formed in the edge member 120 to protrude outward. And in many places there may be a hole 113 to be a moving passage of the enemy.

The electrode plate 110 is connected to the edge member 120 through the protrusion 111, and the remaining edges except for the protrusion 111 are arranged to be spaced apart from the inner side of the edge member 120 by a predetermined distance so that raw water can be distributed. Form a space (it can be called a part of raw water storage room).

An end portion of the protrusion 111 forcedly inserted into the through hole 121 of the frame member 120 is exposed to the outside and electrically connected to the wire 80, and is in contact with the inner through hole 121 of the frame member 120. It may be desirable to prevent the raw water from leaking through the through hole 121 by sealing silicon or the like in the protrusion of the portion.

In the electrolytic cell 100 of the present invention, four electrode plates 110 were arranged side by side, and each electrode plate 110 was different in polarity from an adjacent electrode plate 110. That is, when a positive polarity DC current is applied to the first and third electrode plates 110, a negative polarity DC current is applied to the second and fourth electrode plates 110. do.

Since the electrolytic cell of the present invention has a structure in which a plurality of electrode plates are stacked and assembled, an electrolytic cell can be provided with an appropriate number of electrode plates depending on the desired concentration of silver ions.

In the case where silver is plated on the electrode plate 110 (including a pure silver plate), the plated silver Ag is electrolyzed and silver (Ag) in the electrode plate 110 to which a positive polarity current is applied. In the electrode plate 110 where ions and electrons are generated, and the negative polar current is applied, hydrogen ions dissolved in raw water are combined with the electrons generated in the positive electrode plate 110. A reduction reaction occurs in which hydrogen gas is produced. In addition, a small amount of silver (Ag) ions generated in the (+) polarity is adsorbed to the electrode plate 110 of the (-) polarity.

Therefore, when the polarity of each electrode plate 110 is maintained at the same polarity for a long time and the electrolysis is increased, the positive electrode plate 110 becomes thinner by gradually disappearing the plated silver, and the negative electrode plate of the (-) polarity. 110, the plated silver is unchanged or rather thickened.

Thus, although the (-) polar electrode plate 110 is plated with a sufficient amount of silver, the (+) polar electrode plate 110 does not have silver and thus does not emit silver ions, so the replacement time of the electrode plate 110 is advanced. You lose. In order to solve this problem, it is preferable to periodically change the polarity of the electrode plate 110 so that the silver plated on all the electrode plate 110 is dissipated at a similar speed. In this way, the circuit unit 200 controls the supply of power so that the polarity of the electrode plate 110 is periodically converted.

The edge member 120 has an opening 125 formed at the center thereof, and the electrode plate 110 is arranged in the opening 125, so that the edge member 120 surrounds the edge of the electrode plate 110.

And the inner side of the frame member 120 is formed with a plurality of support parts 122 protruding inward to support the electrode plate 110 which is spaced at a predetermined distance in various places,

Each of the upper and lower surfaces has a guide groove 127 and a guide protrusion (female and female) coupled to guide the other edge members 120 or the upper cover 130 or the lower cover 140 which are stacked in position to be laminated and coupled. 128 is formed. The guide grooves 137 and 147 and the guide protrusions 138 and 148 are formed on the upper surface of the lower cover 140 and the lower surface of the upper cover 130, respectively.

And each of the upper surface and the lower surface of the rim member 120 is formed with a settling groove 123 in which the packing 150 is placed. The depth of the settling groove 123 is about 3/1 of the thickness of the packing 150, the insertion protrusion 124 is formed in the corner of the settling groove 123 is inserted into the insertion hole 154 of the packing 150. It is. The settle grooves 133 and 143 and the insertion protrusions 134 and 144 are also formed in the upper cover 130 and the lower cover 140.

In addition, the inner edge of the frame member 120 is formed with another settle groove 126 in which the contact blocking member 160 is placed.

The contact blocking member 160 is disposed between the electrode plates 110 to support one surface of the electrode plate 110 and prevent the electrode plates 110 from contacting each other.

The contact blocking member 160 includes a plurality of separation bars 161 spaced at a predetermined distance to minimize contact blocking of the electrode plate 110 and the raw water, and the separation bar 161 is a flow path for the raw water. A plurality of flow path grooves 163 are formed.

The lower cover 140 and the upper cover 130 are respectively disposed on the upper and lower portions of the electrolytic cell 100, and a plurality of edge members 120 are disposed therebetween.

In addition, the lower cover 140 and the upper cover 130 are provided with the settle grooves 133 and 143, the insertion protrusions 134 and 144, the guide grooves 137 and 147, and the guide protrusions 138 and 148, such as the rim member 120. Since the contact blocking member 160 is not disposed, the stepped parts 136 and 146 protrude from the center to support one surface of the electrode plate 110 instead of the contact blocking member 160, and the edge members are formed on the stepped parts 136 and 146. Receiving grooves 135 and 145 are formed to accommodate the support portion 122 of the (120).

The lower cover 140 or the upper cover 130 is provided with an inlet 131 and a drain 132 through which raw water flows in and out, and a fixing hole 149 is formed to fix the electrolytic cell 100 to the main body. It is.

The packing 150 is placed in their settled grooves (123, 133, 143) so as to be disposed between the rim member 120 and the upper cover 130 and the lower cover 140 to seal the gaps in the raw water receiving chamber Do not let the contained water run out through the gap.

The packing 150 has a concave shape where its bottom surface is flat and its diameter gradually narrows toward the top. The bottom surface is flat so that the bottom surface is in close contact with the settling grooves 123, 133, 143, and gradually narrowing toward the top is laminated frame member 120 (or upper cover 130, or lower cover 140) In order to be easily placed in the settled grooves (123, 133, 143) in the lamination process.

The thickness of the packing 150 is greater than the sum of the depths of the two settling grooves 123, 133, and 143 which are stacked to press and fix the stacked frame members 120, the upper cover 130, and the lower cover 140. It is preferable to tightly close the gap between the ones in which 150 is pressed and laminated.

In addition, the corners of the packing 150 are integrally formed with an extension part 151 having an insertion hole 154 into which the insertion protrusions 124, 134, and 144 formed at the corners of the settled grooves 123, 133, and 143 are inserted. .

The electrode plate 110 is coupled to the edge member 120, and the edge members 120, the upper cover 130, and the lower cover (120) are disposed with the packing 150 and the contact blocking member 160 disposed therebetween. After stacking 140, the fastening bolts 171 are inserted into fastening holes h formed through upper and lower portions of their edges, and tightened with nuts 172 to press and fix them.

As described above, in the electrolytic cell 100 in which the components are assembled, the electrode plates 110 are disposed adjacent to each other but are not in contact with each other, and the entire electrode plate 110 is submerged in raw water, and the raw water receiving chamber has a larger area than the electrode plate 110. It needs to be a little bit bigger, so the ion production rate is high, but it can be miniaturized.

According to the capacity of the water purifier, the number of electrode plates stacked and assembled is appropriately increased, so there is no need to install an additional electrolytic cell.

Since the protrusion 111, which is a part of the electrode plate 110, is exposed to the outside of the electrolytic cell 100 and connected to the wire 80, there is no restriction that the electrolytic cell 100 should be installed upright or laid down, and flows into the raw water storage chamber. Since there is no restriction on the hourly inflow rate of the raw water, there is no need for a separate means for controlling the amount of raw water inflow, and it is also possible to install it by connecting directly to the water supply pipe.
