The following description relates to the operation and advantages of the present invention constructed as described above.

If the water tap (not shown) connected to the water purification device of the present invention is opened, the tap water will flow through a set of filter assemblies 350 to obtain purification due to the water pressure applied to the water tap and the pressure generated by the working compression pump 400 .

When the tap water from the faucet flows through the inside of the sediment filter 351, floating impurities in the tap water such as rust can be eliminated. The water is then passed through a pre-treatment filter 352, which removes chemicals such as chlorine, etc. from the water. After pretreatment, the water enters the reverse osmosis filter 353 to remove heavy metals and carcinogens in the water.

Subsequently, the odor and toxic gas in the water are eliminated by the post-treatment filter 354 . The sanitizing filter 355 first sanitizes the water from the post-treatment filter 354 . The water is then supplied to the purified water storage tank 330 .

A part of the purified water in the purified water storage tank 330 is supplied to the hot water tank up to a full level through the fourth connection hose 373 connecting the rear of the purified water storage tank 330 with the rear of the hot water tank 360 . In addition, a part of the purified water is injected into the cold water container 450 through the third water outlet 336 formed at the bottom of the purified water storage tank 330 until the water level is full. Once the water in the purified water storage tank 330 and the hot and cold water containers 360 and 450 reaches the full water level respectively, the compressor pump 400 is stopped according to the output signal of the water level sensor 380, and the tap water supply is cut off at the same time. The water level sensor 380 is installed in the purified water storage tank. The cover 332 of the tank 330 is used for multi-level detection of the purified water level.

If the respective water levels of the purified water storage tank 330 and the hot and cold water containers 360 and 450 drop, the water level sensor 380 will perform multi-level detection of the water level in each container, and the measured water level will pass through the transparent part on the console 290 of the front panel 220 293 is displayed on the display 301 of the main printed circuit board 330 . This display tells the user the amount of water consumed in the purified water storage tank 330 and the hot and cold water containers 360 and 450 so far.

The sterilizing lamp 390 installed on the cover 332 of the purified water storage tank 330 has a tip, which is vertically inserted into the cold water container 450 at a certain height through the third water outlet 336 formed at the bottom of the purified water storage tank 330, and it has a certain effect on the purified water. The water in the storage tank 330 and the cold water container 450 is sterilized for the second time simultaneously. The ultraviolet rays sent from the disinfection lamp 390 irradiate the purified water in the purified water storage tank 330 and the cold water container 450, effectively preventing the propagation of microorganisms that may exist in the water that the purified water storage tank 330 has not discharged for a long time, thereby preventing secondary Secondary bacterial contamination.

If the heater (not shown) of the hot water tank 360 works, it is heated to a predetermined temperature according to the electric current, so that heat is transferred to the purified water in the hot water tank 360 .

When the heat transfer assembly 492 of the fan 470 and the heat exchanger 490 works, the motor 471 of the fan 470 makes the fan 472 rotate, and due to the rotation of the fan 472, the external air flows into the main body 200 through the bell-shaped opening 211 in the middle of the bottom panel 210, thus directly blowing to heat sink 495 of heat exchanger 490 .

The radiator 495 is cooled by the external cold air, and according to the electrical characteristics of the heat transfer assembly 492, the purified water in the cold water container 450 is cooled and sent to the cold sink (cold sink) 491 to the outside due to the continuous heat release cooling cycle.

When the user tries to obtain the cold and hot water in the purified water storage tank 330 or the cold and hot water container 450 or 360 with a cup (not shown), he must press a water purification button (not shown), and simultaneously press the Press the power button (not shown) on the console 290 of the front panel 220, and place the cup just under the water distribution hose 550 and then press the button 310 protruding in the middle of the bottom of the front panel 220.

When the button 310 moved backward, a movable contact and a fixed contact (not shown) in the button 310 sent an "ON" signal to a microcomputer (not shown), which interpreted the input program according to the input program. The input data and open the first electronic valve 530, so just open the water channel. When the water passage is opened, the purified water in the purified water storage tank flows through the drain hose 540 connecting the purified water storage tank 330 and the first electronic valve 530 , and flows to the cup through the water distribution hose 550 connected with the first electronic valve 530 .

The water collected by the water tank 320 is discharged to the outside through a water guide pipe (not shown) connecting the water tank 320 and the drain control valve 460 during the water supply process.

As described above, according to the sterilizer of the water purification device of the present invention, the sterilizing lamp is installed between the purified water storage tank storing purified water and the cold water container installed therebelow. The present invention is characterized in that ultraviolet rays are used to perform secondary disinfection on purified water stored in purified water storage tanks and cold water containers and to prevent secondary bacterial contamination of purified water stored for a long time.

Undoubtedly, those skilled in the art can make various modifications and changes to the sterilizer of the water purification device of the present invention without departing from the essence or scope of the present invention.
