A handle 18 is provided. Therefore, it becomes easy to move to a familiar water source. In addition, a power line 19 is led out from the back wall 14.
Next, the purification process of drinking water will be described together with the system configuration of the water purifier with reference to FIG.

  First, the power line 19 is connected to a battery (not shown) to supply power to the main body 1. Next, the supply water tube connected to the supply water port 6 is put into the raw water Rw such as well water, pool water, etc., the front door 11 is opened, the operation switch is turned ON, and the self-priming pump 36 is operated. Rw is sent to the main body 1. The self-priming pump 36 is connected to the first filter 32 and the second filter 33, and the raw water Rw sent from the self-priming pump 36 is free of fine dust and rust by the first filter 32. Residual chlorine is mainly removed by the second filter 33.

  A reverse osmosis membrane module (RO module) 31 is connected to the second filter 33 via a reverse osmosis membrane module pressure pump (RO module pressure pump) 31a. The reverse osmosis membrane module pressurization pump (RO module pressurization pump) 31 a is a diaphragm pump and has a function of pressurizing the water filtered by the second filter 33 and feeding it to the reverse osmosis membrane module 31. . In the reverse osmosis membrane module 31, organic substances, inorganic ions, and the like are separated and removed. In this case, the reverse osmosis membrane module 31 separates the permeated water from which organic substances and the like have been removed and the concentrated water Cw, and the permeated water is sent from the take-out part to the pressure water supply tank 2, and the concentrated water Cw is discharged from the drainage part 7 is sent to the outside.

  The permeated water (product water) purified by the reverse osmosis membrane module 31 is stored in the pressure water supply tank 2, and when the air pressure outside the reservoir 22 rises, the product water stored from the pressure water supply tank 2 is supplied to the water. It becomes possible.

  Next, a flowing water type ultraviolet germicidal lamp 34, a third filter 35, and a movable dedicated water tap (water sampling gun) 81 are connected to the subsequent stage of the pressure water supply type tank 2. Therefore, the production water sent from the pressure water supply type tank 2 is irradiated with ultraviolet rays by the ultraviolet sterilization lamp 34 to sterilize viruses and the like, and further, the third filter 35 removes odors and the like and is finally processed.

  The final treated production water is sampled as drinking water purified through the sampling gun 81 from the production outlet 8 and is used. The pressure water supply tank 2 is provided with a pressure switch, and the operation and stop of the water purifier are automatically performed by the operation of the pressure switch.

  As an option, a hypochlorous acid supply device 9 may be connected between the reverse osmosis membrane module 31 and the pressure water supply tank 2. By connecting this hypochlorous acid supply device 9, it becomes possible to sterilize viruses and bacteria contained in the water in the pipe.

  Moreover, the water purifier of this embodiment connects the piping of a water supply etc. to the supply water port 6 on a daily basis, uses tap water as raw water, purifies this, and refined drinking water or milk for milk preparation It can be. In this case, a commercial power source can be used as the power source.

  In the water purifier having such a configuration, it is possible to obtain highly safe purified water due to pretreatment with a multi-stage filter, advanced water treatment technology with the reverse osmosis membrane module 31, and further, the bactericidal effect of the ultraviolet germicidal lamp 34. Moreover, since the main body 1 is made of stainless steel, rust and the like are not easily generated even when wet, and the main body 1 can be excellent in durability. Furthermore, since the instruments can be visually recognized from the transparent display window 11a of the front door 11, the display of the instruments can be easily seen, and the replacement time of the filter can be easily grasped by the display of each pressure gauge and the water quality meter. .

  Here, a first filter 32 and a second filter 33 are connected as a prefilter between the supply water port 6 and the pressure water supply tank 2, and a reverse osmosis membrane which is a main component of separation filtration. Module 31 is connected. Since these filters are connected to the raw water Rw side upstream of the pressure water supply tank 2, they capture a large amount of impurities and are likely to be clogged as compared with the third filter 35 as the final filter of the rear stage. For this reason, the first filter 32, the second filter 33, and the reverse osmosis membrane module 31 are exchanged more frequently than the third filter 35. Therefore, since the filters having a high replacement frequency are arranged in an integrated manner, the replacement work can be easily performed. In addition, since the first filter 32 and the second filter 33 are disposed as pre-filters in the previous stage of the reverse osmosis membrane module 31, clogging of the reverse osmosis membrane module 31 as a separation filtration membrane is suppressed. The reverse osmosis membrane module 31 is protected.

Furthermore, since the third filter 35, which is a final filter, is arranged near the production water port 8, it is easy to connect the third filter 35 and the production water port 8, and the water distribution pipe (water distribution tube) is shortened. It becomes possible.
Moreover, since the pressure water supply type tank 2 has a capacity of about 50 L and can sample drinking water without a driving source such as a power source, it is possible to meet a temporary demand.

  Since the control panel part 4 is provided in the upper part of the main body 1, it can avoid dangers, such as an electrical leakage, and can provide a highly safe water purifier. Furthermore, since the caster 17 and the handle 18 are provided, the movement becomes easy.

  Furthermore, a small diaphragm pump is mounted as the self-priming pump 36 and the reverse osmosis membrane module pressurizing pump 31a, and the power source is about 100 liters of drinking water per hour with a current amount of 100 V AC, 50/60 Hz, 2 A. It can be watered, consumes less power, and is designed to save energy. Further, even when a small battery is used as a power source, it is possible to operate for a long time.
