As shown in FIG. 1, the water filter 110 includes four filters 111, 112, 113, and 114. The first filter in which tap water supplied through the tap water is introduced is a pretreatment sedimentation filter 111. The pretreatment sedimentation filter 111 is initially removed by removing fine impurities having a size of 5 micrometers such as rust, soil, sand, and various debris. This filter maximizes the water purification effect at the stage.

As such, the primary purified water that has passed through the precipitation filter 111 flows into the first carbon filter 112 through the first solenoid valve 121 and the pressure pump 125. Carbon filter is a filter that uses the adsorption method of activated carbon, and absorbs and removes organic chemicals and odors such as chlorine (trihalomethane) into water close to nature.

Therefore, a drain pipe 147a is connected to the reverse osmosis filter 113 to discharge the filtered residue.

The third purified water passing through the reverse osmosis filter 113 passes through the second carbon filter 114 and is fourth order purified to exit the purified water filter unit 110. The second carbon filter 114 is a filter that removes unpleasant odors, tastes, pigments, etc. penetrated into water as a final stage of the water purifier to make colorless and odorless clean water.

As such, the purified water passing through the four filters 111, 112, 113, and 114 is introduced into the reservoir 131 through the first pipe 141, and the first pipe 141 is connected to the lower portion of the reservoir 131. The second pipe 142 is connected to the upper portion of the reservoir 131. Therefore, the purified water introduced into the water storage tank 131 through the first pipe 141 is stored in the water storage tank 131 and the water level is increased, and discharged to the cooling unit 150 through the second pipe 142, The purified water passing through the cooling unit 150 flows along the third pipe 143 and the branch pipe 144.

As the purified water passes through the heating unit 130 and the cooling unit 150 as described above, the purified water is sprayed in a state of obtaining or losing heat. This constant temperature control will be described later in detail. Hereinafter, a transfer means for moving the nozzle 162 forward and backward in the process of spraying through the nozzle 162 will be described.

As shown in Figure 2a, the transfer means 170 is installed inside the wall (1), and advances the nozzle 162 through the hole formed in the wall (1), the purified water through the nozzle 162 When spraying, the nozzle 162 is advanced to the outside of the wall, and when the spraying is completed, the nozzle 162 is reversed to flow into the inside of the wall (1).
