The present invention relates to a cold water ionizer, and more specifically, to install a uniform pressure water supply means between the filter portion and the electrolytic cell of a conventional cold water heater composed of a filter portion, an electrolytic cell, a cold water tank, an alkaline water discharge pipe and an acidic water discharge pipe. At the same time, the bottom structure of the cold water tank is formed to be inclined or inclined in the form of an arc of convexity so as to be in contact with the drain outlet, and a cleaning nozzle is installed at the upper center thereof, thereby being supplied from the filter unit through the uniform pressure water supply means. In addition to supplying purified water to the inside of the electrolytic cell at a uniform pressure, the generation of scale is blocked in accordance with the flow of alkaline water supplied at a uniform pressure from the electrolytic cell inside the connection pipe connecting the electrolytic cell and the cold water tank, The fine scales that precipitated during draining It relates to a water heater water jacket for the cob to be more smoothly discharged to the outside compared to a cold water tube in a flat surface structure.

In recent years, interest in water has increased due to the increase of adult diseases with serious water pollution, and one of the major causes of adult disease in modern people is the acidification of the constitution due to excessive intake of white rice, flour, meat, etc. As a method for improving the weak alkali constitution, an ionizer for drinking alkaline ionized water is used.

At this time, the ionizer is largely divided into a cold ion water heater equipped with only a cold water tank and a cold ion water heater equipped with a cold / hot water tank, respectively, this cold water tank is divided into a post-cooling method and a pre-cooling method according to the front and back of the electrolytic cell do. That is, if the cold water tank is located behind the electrolyzer based on the ionized water treatment step, it is a post-cooling method.

Hereinafter, the cold water ionizer (patent publication No. 2004-0111251) of the post-cooling method in which the cold water tank is installed behind the electrolytic cell will be described in detail.

In general, after-cooling cold ion water heater 200, as shown in Figure 1, by the electrolytic decomposition of the filter unit 300 for purifying the raw water supplied from the water and the purified water supplied from the filter unit 300 An electrolytic cell 310 for separating alkaline water and acidic water, a cold water container 320 for storing / cooling the alkaline water supplied from the electrolytic cell 310, and the alkaline water in the cold water container 320 may be discharged to the outside for drinking. Reservoir tank 330 and hot water tank in the structure of the cold water heater 210 composed of an alkaline water discharge pipe 316 is installed on the outlet side (not shown) and the acidic water discharge pipe 317 for discharging the acidic water from the electrolytic cell 310 That is, by providing a water tank 330 and the hot water tank 340 connected to the water tank 330 between the filter unit 300 and the electrolytic cell 310, the conventional cold ion water heater 200 is provided. Will be constructed.

Reference numeral 303 denotes a connecting pipe 303 for supplying purified water, 305 denotes a solenoid valve 305, and 331 denotes a reservoir connecting pipe 331.

When considering only the structure of the cold water heater 210 excluding the water tank 330 and the hot water tank 340 of the conventional cold and hot water heater 200 configured as described above, the raw water supplied from the water is purified while passing through the filter unit 300 After this, the positive electrode (not shown) and the negative electrode (not shown), the diaphragm (not shown) through the electrolysis of the electrolytic cell 310 is installed is separated into acidic and alkaline water. In addition, the alkaline water separated through the electrolytic cell 310 is supplied to the cold water container 320 to be stored / cooled, and is connected to the cold water container 320 while being taken out to the outside through an alkaline water discharge pipe 316 having a blowout lever installed therein. Will be made.

However, in the conventional cold ion water heater 200 provided with the water tank 330 and the hot water tank 340 in the structure of the cold water heater 210, the cold ion water heater 210 itself is connected to the hot water tank 340. Since it is made to be supplied directly from the filter unit 300 without receiving the purified water from the installed water tank 330, the raw water is not supplied at a constant pressure from the tap water, or if the supply pressure of the raw water is low electrolytic cell 310 Regardless of the supply amount of the purified water supplied therein, there is a big problem such that the electrolytic action in the electrolytic cell 310 is made by using a constant power, resulting in a very large power loss and power consumption.

In addition, as the pressure of the raw water supplied from the tap water is not constant or supplied at a low pressure as described above, the alkaline water separated through the electrolysis of the electrolytic cell 310 may not be sufficiently generated as required by the user, If it is stored in the cold water container 320, the amount of alkali consumed in the cold water container 320 is not filled as much as the number of alkaline water in the cold water container 320 is larger than the number of consecutive alkaline drinking water of the user. There was also a problem that the user has to wait until the alkali water is stored in the cold water tank 320 to a certain level.

In addition, as described above, the cold ion water heater 210 has no structure for supplying purified water at a constant pressure into the electrolytic cell 310 and the cold water tank 320 via the filter unit 300. Therefore, when the raw water is not supplied from the tap water at a constant pressure as described above or when the raw water is supplied into the electrolytic cell 310 through the filter unit 300 at a low pressure, the raw water is separated into acidic and alkaline water through electrolysis. When the electrolytic cell 310 of the function is used for a long time, the generation of the scale formed in the electrolytic cell 310 by contacting the internal air and the alkali water is generated. That is, the water pressure of the purified water supplied from the filter part 300 to the electrolytic cell 310, that is, constant It is not possible to block or prevent only by the flow of purified water according to the low or low water pressure, in particular, the alkaline water separated from the acidic water from the electrolytic cell 310 is cold water The scale is also generated inside the connection pipe 315 connecting the electrolytic cell 310 and the cold water tank 320 in the state supplied to the 320 and eventually connected to the cold water tank 320 from the electrolytic cell 310. There was also a problem that the flow path of the alkaline water is blocked and the alkali water supply to the cold water tank 320 is blocked.

On the other hand, in the case of the cold water tank 320 for storing / cooling the alkaline water in the structure of the cold ion water heater 210, as shown in Figure 2, while forming a cylindrical body of the flat bottom shape of the upper space ( A safety plate 325 for partitioning into A) and the lower space (B) is installed, the lower space (B) in which the cooling pipe 328 is installed on the outer circumferential surface of the alkali water supplied to the upper space (A) at the center of the safety plate (325). The through-hole 325a is formed to flow to the), in particular, the alkaline water from the electrolytic cell 310 to the upper space (A) of the cold water tank 320 through the connecting tube 315 is generated as described above Fine scales are formed on the bottom surface of the upper space (A), that is, the upper surface of the safety plate 325 having the through hole 325a formed in the center thereof, while being introduced together with the fine scales detached from the inside of the connecting pipe 315. It is to be settled, the cold water tank 320 in such a state When long-term use, the through-hole 325a in the center of the safety plate 325 for flowing alkaline water to the lower space (B) of the cold water tank 320 by the fine scales deposited on the upper surface of the safety plate 325 is blocked; In addition, the supply of alkaline water to the lower space (B) of the cold water container 320 is blocked, and eventually there is a problem that the user can not drink cold alkaline water.

In addition, when looking at the structure of the cold water tank 320, the air is made in a sealed form so that contact with the alkali water stored in the cold water tank 320 is made, but the cold water tank 320 from the electrolytic cell 310 as described above When alkaline water flows into the upper space (A) of the micro-scales are introduced into the bottom space of the upper space (A) while flowing together with the fine scales detached from the inside of the connecting pipe (315), it is discharged to the outside In addition, the drain outlet 329 is formed at one upper end (not shown in FIG. 2) to clean the sedimentation scale of the cold water tank 320 itself, and the like. Even though the drain outlet 329 is formed at the lower end of the cold water tank 320, since the bottom surface of the cold water tank 320 has a flat structure, the sedimentation scale according to the cleaning operation is flat. Has along the bottom surface is very difficult to be transferred to the drain outlet 329 structural problems.

The present invention devised in order to solve the above problems, the uniform pressure water supply means between the filter unit and the electrolytic cell of the conventional cold ion water heater composed of a filter unit, electrolytic cell, cold water tank, alkaline water discharge pipe and acidic water discharge pipe. At the same time, the bottom structure of the cold water container is formed to be inclined or inclined in a convex arc shape so as to be in contact with the drain outlet, and a cleaning nozzle is installed at the top center thereof, so that the filter unit is provided through the uniform pressure water supply means. In addition to supplying purified water supplied from the electrolyzer at a uniform pressure, and blocking the formation of scale according to the flow of alkaline water supplied at a uniform pressure from the electrolyzer into the connection pipe connecting the electrolyzer and the cold water tank. Its purpose is to.

In addition, in the cold water heater to which the cold water container of the present invention is applied as described above, the bottom structure of the conventional cold water container having a flat bottom surface is inclined or inclined in a convex arc shape so as to be connected to the drain outlet. By installing the cleaning nozzle in the center of the upper end, imparting and improving the cleaning function of the cold water tank itself with respect to the precipitated scale, and the fine scales deposited during the drainage work by the cold water tank cleaning are gathered toward the drain outlet side.
