The present invention relates to a drinking water extraction device of the reverse osmosis cold, hot water purifier, and in detail, it is possible to extract cold water and hot water and room temperature water through a single collection pipe or discharge pipe, the storage tank for cold water and room temperature water in one cylinder It is intended to simplify the structure according to the installation.

Reverse osmosis water purifiers are widely known in the art to purify raw water through a pretreated activated carbon filter, a membrane filter, and a post treated activated carbon filter in order to remove various minerals, organics, and residual chlorine mixed in raw water of tap water. In addition to water purification, the reverse osmosis cold and hot water purifiers, which have added convenience to their use, have been re-appeared by improving the use of heating or cooling purified water to extract and drink hot and cold water directly from the water purifier. will be.

However, the cold, hot water purifier, and cold and hot water heaters have been manufactured and installed separately for each type of water, namely, cold water, hot water, and room temperature water, and coke for taking out cold water, hot water, and normal temperature water, respectively. As the number of parts to be used separately had to be installed separately, the internal structure and appearance of the main body of the device became complicated, and the increase in the manufacturing process caused various price increase factors, and the failure rate also increased. As a result, frequent after-sales service was needed.

In addition, in using this, the user has to move and move the cup around in order to find the coke to extract the necessary water, and it has been a hassle and inconvenience in using it, and after removing the cup from the coke after taking out the water, the inside of the coke The small amount of water left in the water dropped to the floor where the water purifier was installed, dropping one or two drops, making the area dirty and unsanitary.

In addition to the above problems, there are various problems in the use of general reverse osmosis cold and hot water purifiers, and thus an effective improvement thereof is required. First, when there is no water in the cold water tank or the hot water tank, freezing of the cold water tank due to supercooling and To prevent damage to the parts due to overheating or fire, there is a inconvenience in using cold water and hot water tanks, and after confirming them, turn on the power switch.The reliability of the purified water is clearly purified. It could not be confirmed. That is, the membrane filter used in the reverse osmosis water purifier generally has a fine pore of 0.001-0.0001 microns and thus has a high effect of removing various contaminants. As the pores are fine, contaminants accumulated inside the filter accumulate and these contaminants Most of the water is washed away by the washing water and discharged through the wastewater channel, or as the remaining pollutants continue to accumulate on the membrane surface, the water purification function of the filter is gradually reduced, and the water quality of the purified water is naturally reduced. Therefore, the longer the filter is replaced, the less the reliability of the purified water cannot be activated, and the life of the membrane filter varies greatly depending on whether or not the washing water control valve is controlled. In other words, the discharge state of pollutants discharged through the wastewater channel is greatly changed depending on the control state of the washing water control valve, which greatly affects the life of the membrane filter. If it is adjusted, excessive opening of the valve causes a lot of waste of water or, conversely, leaving the valve in a closed state results in severe contamination of the filter, which in turn significantly shortens the life of the filter.

In addition, after the purified water is stored in the storage tank and stays in a stagnant state for a long time, the water is contaminated by the microorganisms in the air. In other words, the reverse osmosis water purifier uses silver activated carbon as a material for the post-treatment filter to secure antibacterial ability, so that the post-treatment filter itself has considerable antibacterial ability, but antibacterial ability in the storage tank is not expected. There was a problem with the stability caused.

The present invention solves the various problems caused by the use of the reverse osmosis water purifier as described above, to automatically discharge it according to the contaminated state to extend the life of the membrane filter, and usually in a certain amount of washing water Only when the purified water is stored in the storage tank is automatically circulated to prevent secondary contamination by microorganisms, dissolved oxygen is increased so that you can always drink clean drinking water, cold as one outlet It is an object of the present invention to allow the selection and extraction of hot water and room temperature water, and to integrate the storage tank into a single cylinder to achieve structural simplification and to avoid overcooling and overheating of the cold and hot water tanks.

Referring to the integer cycle structure of the present invention in detail based on the drawings as follows.

As shown in FIG. 1, the present invention is provided with a high turbidity filter (1) and a sedimentation filter (2), which primarily filter foreign matter having relatively large particles such as sand and green waste mixed in raw water of tap water. A conventional pretreatment activated carbon filter (4), a membrane filter (5), a post-treatment activated carbon filter (6), which are connected via the precipitation filter (2) and the pump (3), and the final sterilization treatment of the purified water passed through them in order U / V filter 7 is provided for the basic structure of the general reverse osmosis water purification structure composed of a storage tank 8 for storing the purified water passed through the water treatment step.

The present invention is the water level control valve 10 and the water level safety shut-off valve (11) of the sediment filter (2) that can check the quantity and water pressure of the incoming raw water while using the basic structure as described above The pump is stopped by detecting a new installation at the rear stage or when the sedimentation filter (2) is clogged and insufficient inflow of raw water through it, and the automatic washing valve (15) in the wastewater discharge line of the membrane filter (5). ) And a separate circulation pump 12 is installed between the storage tank 8 and the U / V filter 7 so as to automatically circulate the stored water in the storage tank 8 at regular intervals. The circulating pump 12 is operated at a predetermined time interval by the capacitance level sensor 13 and 14 measuring the time, and the storage water in the tank 8 is pumped through the circulating pipe 16 to the U / V filter ( 7) to circulate back into the storage tank (8) It prevents stagnation of stored water for a long time so that water always flows.

As the stored water is continuously circulated, the dissolved oxygen rate dissolved in the water is increased, and the sterilization device is sterilized again by the U / V filter (7), so that it is not contaminated by microorganisms and the water quality may deteriorate even if the water is not used for a long time. There will be no at all.

In addition, in the present invention, by forming a recess in a constant volume at the bottom of the room temperature storage tank 8 so that the storage tank 8 and the cold water tank 17 are integrated, the hot water tank 18 is installed separately but the hot water tank ( By making the water level that is one third of 18) and the lowest water level of the storage tank 8 located on the same horizontal line, and installing the capacitance low level sensor 13 at the lowest water level position of the storage tank 8 Cold water tank (17) is always in full water, hot water tank (18) is filled with water up to 1/3 point, the heater and cooling compressor is designed to operate in a state in which the heater 19 is locked, one structural feature By such a structural feature, it is possible to fundamentally solve the cause of overcooling of the cold water tank 17 and the overheating of the hot water tank 18, which were not solved by the existing cold and hot water purifiers.

Another structural feature of the present invention by omitting the installation of coke was to increase the number of coke installed in order to take out the coke water according to the type of water (cold water and hot water and room temperature water) in the existing cold, hot water purifier to 2-3 It is configured to be able to take out only the collection pipe or the discharge pipe of the. That is, as shown in (a) of FIG. 3, the discharge ports 21a and 22a of the valves 21, 22 and 23 for cold water, hot water and normal temperature water using the electric 3-way solenoid valve 20 are shown. Assemble the induction pipes (25a) (25b) (25c) in the (23a) and connect them to one water collecting pipe (25), and select the type of water to be extracted, such as cold water, hot water, and room temperature water switch (not shown) By pressing, only the selected valve 21 or 22 or 23 is operated so that the selected water is drawn out through the collecting pipe 25 along the induction pipe 25a or 25b or 25c.

In addition, as shown in (b), the discharge ports 21a, 22a and 23a of the valves 21, 22 and 23 for cold water, hot water and normal temperature water are covered with the collecting cover 24, and this collecting cover 24 is provided. By forming a single discharge pipe 24a in the column), only the selected valve 21 or 22 or 23 is operated by selecting a type of water to be discharged, such as cold water, hot water, or room temperature water, and pressing the switch, so that the selected water discharges the discharge pipe 24a. It is configured to be extracted through.

In the accompanying drawings, reference numeral 8a denotes a normal temperature water pipe, 17a denotes a cold water pipe, 18a denotes a hot water pipe, 26 denotes a wastewater discharge pipe, 27 denotes a drain pipe, and 28 denotes a drain pipe check valve.

In the practice of the present invention, the three-way solenoid valve 20 may be changed to a two-way solenoid or a four-way solenoid valve as required, and in the case of the two-way valve, the outlet and the induction The pipe is deformed into two, and in the case of 4-way, the discharge port and the guide pipe are increased to four, but only the collecting pipe 25 has a blowout structure composed of all one.

As described above, the present invention provides an efficient control method for the purification system for extending the life of the reverse osmosis membrane and increases the dissolved oxygen of the stored water by circulating the stored water in the storage tank, and sterilizes at regular intervals to block the microbial contamination. As the water purification process progresses and a certain amount of contaminants such as microorganisms, organic chemicals, inorganic contaminants and heavy metals accumulate in the reverse osmosis membrane, the membrane filter is cleaned by the automatic cleaning valve of the water purification system according to the degree of contamination. If the water stored in the storage tank is stagnant for a long time, secondary pollution by microorganisms in the air will proceed. In order to prevent this, the sterilization lamp can be installed directly in the storage tank or A pressure tank was used, the former being made of ordinary plastic If the surface of the tank is not sanitary due to UV rays, it could cause the lamp to be damaged due to user's negligence or carelessness, and the skin may be exposed to UV rays directly. As it is expensive and limited to the under sink type, there is a problem in that it is inconvenient to follow the limitation of use and the problem that the inside of the tank can not be cleaned. Therefore, the use of a retractable storage tank is preferable. As described above, the secondary pollution of the storage water by the microorganisms in the air Since the present invention has a problem of forcibly circulating the storage water of the storage tank having a high possibility of secondary pollution at a constant cycle, the present invention can always obtain the sterile water stored in aseptic state by continuously passing the sterilizer (U / V filter). Will be.

After all, the control of the reverse osmosis water purification system and the circulation system according to the present invention, the automatic washing valve 15 is effectively washed according to the degree of contamination of the reverse osmosis membrane filter (5), which is the core filter of the reverse osmosis pressure control method. It extends the lifespan and circulates and sterilizes the stored water at regular intervals in the order of the storage tank (8) → U / V filter (7) → circulation pump (12) → storage tank (8) to increase the dissolved oxygen rate and This prevents the safe and hygienic water supply at all times.

In addition, the hot water storage tank (8) and the cold water tank (17) to be integrated, and the separately installed hot water tank (18) is the same as the water level of 1/3 of the inner height and the lowest water level of the storage tank (8) It is positioned on the horizontal line, by mounting the capacitance low water level sensor 13 in the lowest water level position of the storage tank 8, the cold water tank 17 is in a full state, the hot water tank 18 is 1/3 Since the water is cooled until the heater 19 is locked, the heater and the cooling compressor are designed to operate. Thus, the supercooling of the cold water tank 17 and the overheating source of the hot water tank 18 that the conventional cold and hot water purifier have not solved. This is a fundamental solution to the problem.

In addition, the discharge port 21a, 22a, 23a of the cold water, hot water, and room temperature water valves 21, 22, 23 using the electric 3-way solenoid valve 20 is covered or guided by the collecting cover 24. The discharge pipe is operated while only the 3-way solenoid valve selected by connecting the pipes 25a, 25b, and 25c to a single collection pipe 25 assembled by selecting the type of water to be discharged, such as cold water, hot water, and room temperature water. It is configured to be withdrawn through the 24 (a) or through the collecting pipe 25 assembled to the induction pipe (25a) (25b) (25c), so that the number of coke installed to extract it according to the type of water in the existing cold, hot water purifier By eliminating the coke installation that can only be increased to 2-3, the installation can be used with only one collection pipe 25 or the discharge pipe 24a, thereby simplifying the structure, and designing the device body. There is also a synergistic effect.

Particularly, induction pipes 25a, 25b, and 25c are assembled to discharge ports 21a, 22a, and 23a of the valves 21, 22, and 23 for cold water, hot water, and room temperature water. The selected water along the induction pipe 25a or 25b or 25c is operated while only the selected valve 21 or 22 or 23 is operated by selecting the kind of water to be drawn out by connecting to (25) and selecting the kind of water to be drawn out, such as cold water, hot water or room temperature water. In the case of configured to be withdrawn through (25), the tip of the guide tubes 25a, 25b, 25c is sealed while the valve which was operated is closed at the same time as taking out the selected water and then removing the cup from the lever (not shown). The water in the guide tubes 25a, 25b, 25c is kept in a momentary stop state so that water does not flow out. Therefore, the problem that the conventional reverse osmosis water purifier could not solve, that is, after removing the cup in the state of dispensing water, a small amount of water remaining inside the pipe falls by one or two drops to the floor where the water purifier is installed. It is a clear solution to what has become messy and unsanitary.
