The fixed case 210 is detachably fixed to the water purifier main body 100 and supports the movable case 220 so that the movable case 220 can be lifted and lowered while being fixed to the water purifier main body 100. Therefore, the movable case 220 can be raised and lowered while being supported by the purifier body 100 by the fixed case 210. [

The stationary case 210 has a lift 211 in which the moving case 220 is housed, and the lower end of the storage 211 is opened to communicate with the outside. Accordingly, the movable case 220 accommodated in the lifting space 211 can be protruded downward from the fixed case 210.

In this embodiment, the fixing case 210 may be in a state in which a back surface (right side in the drawing) connected to the purifier body 100 is open. For example, the fixing case 210 may include a front portion and side portions extending rearward from both sides of the front portion.

The moving case 220 is fixed to the lower end of the water outlet nozzle 280. The moving case 220 is accommodated in the lifting space 211 of the fixed case 210 and supported by the fixed case 210 to move up and down.

The outer shape of the moving case 220 may be formed to correspond to the shape of the elevation space 211 of the fixed case 210. For example, the fixed case 210 and the movable case 220 may have a rectangular cross section. As another example, the fixed case 210 and the movable case 220 may have a circular cross-section. In addition, the fixed case 210 and the movable case 220 may have various cross-sectional shapes.

Meanwhile, in the present embodiment, the moving case 220 may be in a state where the back surface (the right side in the drawing) facing the purifier body 100 is open. When the rear surface of the moving case 220 is opened as described above, the inner space of the purifier body 100 and the inner space of the moving case 220 can communicate with each other. As a result, 280, and 280 may be connected to a supply hose 190 for supplying at least one of purified water, cold water, and hot water generated in the purifier body 100.

For example, the moving case 220 may include a front portion and side portions extending rearward from both sides of the front portion.

At this time, when the groove is formed in the fixed case 210, the movable case 220 may be formed with a protrusion that is inserted into the groove.

Conversely, when the protrusion is formed in the fixed case 210, the movable case 220 may be formed with a groove into which the protrusion is fitted.

The resistance means 230 is formed in the fixed case 210 or the movable case 220 and has a resistance for reducing the lift force applied to the movable case 220 for raising or lowering the movable case 220. [ Means 230 may be included.

Here, the term 'upward force applied to the moving case 220' refers to all forces that affect the lifting operation of the moving case 220.

For example, the user may be a force to pull down the movable case 220 to lower the movable case 220, or a force to push the movable case 220 upward to raise the movable case 220. Further, the movable case 220 may be a force for descending by gravity.

As described above, when the movable case 220 ascends and descends with respect to the fixed case 210, the movable case 220 can be lowered arbitrarily by its own weight. That is, the moving case 220 can be lowered out of the fixed case 210 by the own weight of the moving case 220 in a state where the moving case 220 is completely housed in the fixed case 210, When the user removes the movable case 220 from the movable case 220 in a state where the movable case 220 is lowered to a desired position, the movable case 220 is not fixed at that position and can be further lowered by its own weight. That is, it is difficult to maintain the height of the moving case 220.

In the case of the present invention, the fixing case 210 or the moving case 220 is provided with a resistance means 230 in order to prevent such a situation.

The resistance means 230 reduces the force exerted on the movable case 220 for raising or lowering the movable case 220.

Therefore, the movable case 220 can be kept in the accommodated state without being arbitrarily lowered by the self weight of the movable case 220 in a state in which the movable case 220 is completely housed in the fixed case 210. [ Further, even if the user holds the movable case 220 and descends to a desired position and the user releases his / her hand from the movable case 220, the movable case 220 can be fixed at that position. Accordingly, the outflow nozzle 280 can be positioned at a height desired by the user, and the outflow can proceed.

At this time, the resistance means 230 should be selected in such a range that the user does not have excessive force to lift and lower the moving case 220, while preventing the moving case 220 from descending due to its own weight. Further, it should be adopted within a range in which the user can improve the operational sensitivity of moving the movable case 220 up and down.

For example, the resistance means 230 may include a material such as rubber having frictional force, or may include a material such as oil having viscosity. In addition, various embodiments may occur within the range in which the resistance means 230 can reduce the force applied to the movable case 220. [

A detailed description of an example of the resistance means 230 will be described later.

In the present invention, an operation unit 410 is provided on the upper surface of the watering module 200, and a water-taking button 420 may be provided on the front surface of the watering module 200.

In order to provide the operation unit 410 on the upper surface of the water outlet module 200 as described above, a storage space for receiving the operation unit 410 may be formed on the upper surface of the fixed case 210.

According to the present invention, the operation unit 410 is provided on the upper surface of the water outlet module 200, so that the overall operation of the water purifier 10 can be easily controlled in the case of a large adult user. On the other hand, in the case of a small-sized user, the operation unit 410 provided on the upper surface of the head module 200 can not be recognized, and even if it is recognized, the operation unit 410 can not be operated easily. It is possible to prevent safety accidents such as burns on the hands.

On the other hand, the outbound button 420 is provided on the front of the outbound module 200 to recognize the outbound button 420 not only for an adult user but also for a small outline user, So that the heading can proceed.

In addition, the water dispenser module 200 may further include a front case 290 covering a front surface of the fixed case 210.

When the front case 290 covers the front surface of the water dispenser module 200 as described above, the structure of the resistance member 230 and the guide part 240, which will be described later, is not exposed to the outside, .

The front case 290 is detachably coupled to the fixing case 210 so that the front case 290 is separated from the fixing case 210 and the resistance member 230 and the guide unit 240 are inspected You may. For example, the front case 290 and the stationary case 210 can be coupled to each other by a hook-and-detachment method.

The front case 290 may include an upper edge 291 coupled to an upper end of the fixed case 210. The operation unit 410 can be received in the rim 291. With the configuration of the rim 291, the coupling force between the front case 290 and the fixed case 210 can be further increased.

In the present embodiment, the front case 290 is provided with an outflow button exposing port so that the outflow button 420 can be exposed to the outside of the front case 290.

The outflow nozzle 280 may be formed of stainless steel.

As described above, when the outflow nozzle 280 is made of stainless steel, it is sanitary because it does not rust and it is possible to prevent breakage and deformation that occur during frequent use. In addition, the water purifier 10 can be made to look beautiful and add a luxurious image to the water purifier 10.

The outflow nozzle 280 may be integrally formed with the moving case 220 or a connecting member 281 connecting the moving case 220 and the outflow nozzle 280 through an insert injection method. have.

The connection member 281 is a component that connects the outflow nozzle 280 and the supply hose 190 and is detachably coupled to the moving case 220.

When the outflow nozzle 280 is integrally formed with the moving case 220 or the connecting member 281 by the insert injection method as described above, the outflow nozzle 280 and the moving case 220 or the connecting member 281, (190), thereby preventing water leakage. In addition, it can be made easier than conventional assembly methods.

FIG. 6 is a front view showing the elevation of the moving case of the watering module, and FIG. 7 is a longitudinal sectional view showing the moving case of the watering module elevated. FIG. 8 is a front view showing a state in which the moving case of the watering module is lowered, and FIG. 9 is a longitudinal sectional view showing a state in which the moving case of the watering module is lowered.

6 to 9, a guide unit 240 may be formed in the fixed case 210 or the movable case 220 to guide the movable case 220 in a straight line.

Since the movable case 220 is lifted and lowered while being accommodated in the fixed case 210, the lifting and lowering operation of the movable case 220 can be linearly guided by the fixed case 210. However, when the movable case 220 is slightly moved to both sides while the movable case 220 is exposed to the outside of the fixed case 210, the up and down movements of the movable case 220 unstably proceed, Repeatedly, the fixing case 210 or the moving case 220 is deformed and damaged.

In the case of the present invention, a separate guide part 240 is provided to prevent this.

The guide part 240 may be variously arranged within a range that the guide part 240 can be guided so that the movable case 220 can be lifted and straightened while being supported by the fixed case 210.

For example, the guide unit 240 may include a linear rail formed in the fixed case 210 in a vertical direction, and a roller formed in the movable case 220 to run the linear rail.

In contrast, the guide unit 240 may include a linear rail formed in the movable case 220 in the vertical direction, and a roller formed in the fixed case 210 to run the linear rail.

The guide portion 240 may include a guide groove 241 formed on the fixed case 210 along the lifting and lowering direction and a guide provided in the movable case 220 and inserted into the guide groove 241. [ (242).

Conversely, the guide part 240 may include a guide groove formed in the moving case 220 along the lifting direction and a guide piece provided in the fixing case 220 and fitted in the guide groove.

At this time, the guide piece 242 is inserted into the guide groove 241 formed in the straight line, and moves linearly along the guide groove 241. Accordingly, the movement of the movable case 220 can be made straight.

Further, the guide piece 242 may be rotatably mounted on the moving case 220.

When the guide piece 242 is rotatably mounted on the moving case 220 as described above, the guide piece 242 is moved along the guide groove 241 in a state where the frictional force with the guide groove 241 is minimized. It can be ascended and descended in a straight line. Therefore, the ascending and descending operations of the movable case 220 can be performed more smoothly, and the user's feeling of operation can be improved.

The guide groove 241 has a first gear tooth 241a formed therein and a second gear tooth 242a engaged with the first gear tooth 241a on the outer circumferential surface of the guide tooth 242 .

That is, the guide groove 241 and the guide piece 242 are engaged with each other in the manner of a rack and a pinion, and the guide piece 242 is rotated and moved up and down along the guide groove 241 .

For example, when the user pulls the movable case 220 downward, the guide piece 242 rotates in the counterclockwise direction in the figure and descends along the guide groove 241 while the gear teeth 241a and 242a are engaged with each other do.

Conversely, when the user pushes the movable case 220 upward, the guide piece 242 rotates in the clockwise direction in the drawing, and moves along the guide groove 241 with the gear teeth 241a and 242a engaged with each other.

When the gear teeth 241a and 242a are formed as described above, since the gear teeth 241a and 242a are engaged with each other, the guide piece 242 can be moved up and down more accurately along the guide groove 241, As a result, the ascending and descending of the movable case 220 can proceed more accurately in a straight line. In addition, the guide piece 242 is prevented from being loosened in the guide groove 241, and the lifting and lowering of the movable case 220 can be proceeded accurately by the user's desired height.

The first gear teeth 241a or the second gear teeth 242a may include a straight section or a curved section formed to be perpendicular or inclined to the moving direction of the moving case 220. [ Particularly, the first gear teeth 241a or the second gear teeth 242a may be formed in a curved shape.

When the first gear teeth 241a or the second gear teeth 242a are formed in a curved shape as described above, the first gear teeth 241a and the second gear teeth 242a can be smoothly engaged with each other, The operation feeling can also be improved. In addition, when the user grasps the movable case 220 and lifts the movable case 220, the force applied to the first gear teeth 241a or the second gear teeth 242a causes the first gear teeth 241a or the second gear teeth 242a can be prevented from being damaged.

If the first gear teeth 241a or the second gear teeth 242a are formed in a straight line and sharp corners are formed, there is a fear that the force is concentrated on the pointed portions and breakage may occur.

For example, the irregularities of the first gear teeth 241a or the second gear teeth 242a may protrude or be recessed in a semicircular shape.

In addition, the shape of the first gear teeth 241a and the second gear teeth 242a is such that the second gear teeth 242a is engaged with the first gear teeth 241a and rotates to securely transmit power, Various embodiments may occur within a range in which the guide piece 242 can move linearly along the guide groove 241. [

In addition, the resistance unit 230 may be formed of an oil damper.

An oil damper means a device that has oil in the housing and absorbs energy by viscous resistance of the oil.

As described above, the oil damper includes a cylindrical housing, an oil filled in the housing and having a predetermined viscosity, a plurality of through holes accommodated in the housing and through which the oil passes, And a rotating shaft connected to the rotating blade.

Therefore, when the rotational force is supplied to the rotational shaft, the rotational force supplied by the viscous resistance of the oil can be reduced.

10 is a perspective view showing a state in which a resistance member and a guide piece, which are a part of the present invention, are connected.

The resistance means 230 may be an oil damper and the guide pieces 242 may be connected to the rotation axis 231 of the resistance means 230. [

That is, when the moving case 220 is lifted to raise or lower the moving case 220, the guide piece 242 rotatably connected to the moving case 220 rotates.

At this time, the rotational force of the guide piece 242 is reduced by the resistance means 230, that is, the oil damper.

Therefore, the movable case 220 can be kept in a housed state without being arbitrarily lowered by the viscous resistance of the resistance means 230 in a state in which the movable case 220 is completely housed in the fixed case 210. [ Even if the user holds the movable case 220 and descends to the desired position and the user releases his / her hand from the movable case 220, the movable case 220 is moved to a desired position by the viscous resistance of the resistance means 230 Can be fixed.

At this time, the oil viscosity of the oil damper is varied in such a range that the resistance means 230 prevents the moving case 220 from descending due to its own weight, while the user does not exert excessive force to lift the moving case 220 . Further, the oil viscosity of the oil damper can be variously adjusted within a range that can improve the operational sensitivity felt by the user.

Figure 11 is a cross-sectional view of an outboard module that is part of the present invention. 12 is an enlarged view showing an area A in Fig.

11 to 12, the fixed case 210 and the movable case 220 may be in line contact with each other.

Here, 'line contact' means that the fixed case 210 and the moving case 220 are in point contact as shown in the sectional views of FIGS. 11 to 12, So that the fixed case 210 and the movable case 220 are in linear contact with the moving case 220 along the vertical direction.

At least one or more contact protrusions 216 and 226 may be formed along the lifting and lowering direction of the movable case 220 in the fixed case 210 or the movable case 220.

For example, when the contact protrusion 216 is formed in the fixed case 210, the contact protrusion 216 contacts the moving case 220 in a line. As another example, when the contact protrusion 226 is formed on the movable case 220, the contact protrusion 226 contacts the fixed case 210 in advance.

As another example, when the contact protrusion 216 is formed in the fixed case 210, a contact groove may be formed in the movable case 220 at a position corresponding to the contact protrusion 216. When the contact protrusion 226 is formed on the movable case 220, a contact groove may be formed in the fixed case 210 at a position corresponding to the contact protrusion 226.

When the fixed case 210 and the movable case 220 are linearly contacted by the contact protrusions 216 and 226 as described above, the frictional force between the fixed case 210 and the movable case 220 is minimized The fixed case 210 and the movable case 220 are held in contact with each other so that the movable case 220 can be stably lifted and lowered. Further, deformation such as warping of the fixed case 210 and the movable case 220 can be prevented as much as possible due to mutual contact and support.

In one example, the contact protrusions 216, 226 may have a convex semicircular cross-section. When the contact protrusions 216 and 226 are curved as described above, the movable case 220 can be smoothly moved up and down in a state where the fixed case 210 and the movable case 220 are in line contact with each other.

The fixed case 210 may have wings 215 extending outward on both sides of the rear side and the moving case 220 may be formed on both sides of the moving case 220, And a bent portion 255b extending inwardly from the extended portion 255a and having a hook 225c formed on an inner side of the bent portion 255b, The wing portion 215 can be received in the receiving groove 227 between the extended portion 255a and the hook 225c.

The end of the fixed case 210 is reinforced by the wing 215 so that deformation such as warpage can be prevented.

The moving case 220 is formed with a receiving groove 227 for receiving the wing 215 so as to increase the fastening force with the fixed case 210 to prevent the moving case 220 from being separated from the fixed case 210, And the fixing case 210 may be prevented from being deformed.

When the wings 215 are formed on the fixed case 210 and the hook 225c is formed on the movable case 220 as described above, the movable case 220 and the fixed case 210 are detachably attached Possibly combined.

In this embodiment, the moving case 220 may include a guide member 225. [

At this time, the guide member 225 may be fastened to the moving case 220 by fastening means 228 such as a bolt.

The extended portion 255a, the bent portion 255b, and the hook 225c may be formed on both sides of the guide member 225. [

Therefore, the guide member 225 is moved up and down along the fixed case 210, and the movable case 220 connected to the guide member 225 can also be moved up and down along the fixed case 210.

The wing portion 215 may have a first contact protrusion 216 formed on a surface thereof facing the extended portion 255a along the lifting direction of the moving case 220. [ The first contact protrusion 216 is in line contact with the extended portion 255a.

A second contact protrusion 226 may be formed on the hook 225c along the lifting and lowering direction of the moving case 220 on a surface facing the wing 215. And the second contact projection 226 comes into line contact with the wing 215.

When the first contact protrusions 216 and the second contact protrusions 226 are formed as described above, the movable case 220 can be lifted and lowered while the fixed case 210 and the movable case 220 are in line contact with each other , The movable case 220 can stably move up and down without being shaken in the front-rear direction.

Since the wing portion 215 is accommodated in the receiving groove 227, the bent portion 255b is supported by the wing portion 215 so that the moving case 220 does not move in the left and right direction, can do.

In addition, inclined surfaces 215a and 225d may be formed on the front surface of the hook 225c and the rear surface of the wing portion 215, respectively.

When the inclined surfaces 215a and 225d are formed on the wings 215 and hooks 225c as described above, it is easy to insert the moving case 220 from the rear of the fixed case 210 forward.

For example, the fixed case 210 and the movable case 220 may be in a state where the back surface is opened.

At this time, the movable case 220 can be inserted from the rear of the fixed case 210. However, when the wings 215 and the hooks 225c are formed, insertion of the movable case 220 is smooth I can not.

In order to prevent this, inclined surfaces 215a and 225d are formed on the front surface of the hook 225c and the rear surface of the wing portion 215 so as to be parallel to each other, 220) can be easily inserted.

A gripping part 272 protruding outward is formed at both lower ends of the moving case 220 and a seating groove 217 in which the gripping part 272 is seated is provided at both lower ends of the fixing case 210 .

At this time, a step 271 may be formed on the upper part of the handle 272. Therefore, when the user holds the handle 272 and raises the movable case 220 upward, the step 271 of the handle 272 is hooked on the seat groove 217. [ As a result, the seating groove 217 can serve as a stopper for restricting the elevation height of the movable case 220.

In addition, a gripping groove 270 may be formed in the handle portion 272 to be recessed inward.

When the gripping grooves 270 are formed as described above, the user can grip the gripping grooves 270 to lower or raise the moving case 220. At this time, the user can lower or raise the movable case 220 without slipping.

As another example, when the moving case 220 is lifted or lowered, the grip portion 272 may be provided with protrusions or protrusions to prevent slippage, or may have grip protrusions protruding outwardly.

At least one of the fixed case 210 and the movable case 220 may be formed of an engineering plastic material having excellent fatigue resistance, toughness, abrasion resistance, etc. and having lubricity.

For example, at least one of the fixed case 210 and the movable case 220 may be made of polyoxymethylene (POM).

Therefore, when the movable case 220 moves up and down in the fixed case 210, wear and noise due to friction between the fixed case 210 and the movable case 220 can be reduced.

In addition, when the user pulls the movable case 220 downward to lower it or raises the movable case 220 that has been lowered, the ascending and descending operations of the movable case 220 proceed smoothly, thereby increasing the operational sensitivity.

On the other hand, a protrusion 314b may be formed inside the tray mounting portion 314. A coupling groove 302 is formed in the tray coupling portion 301 so that when the tray coupling portion 301 is inserted into the tray mounting portion 314, the projection 314b is inserted into the coupling groove 302, So that the tray 300 can be maintained in a state in which the tray 300 is mounted on the rotation ring 310. In addition, when the tray 300 is mounted, it can be easily recognized that the protrusion 314b and the coupling groove 302 are engaged with each other. The tray 300 may be coupled to the rotation ring 310 and rotated in the left and right directions with respect to the base 113 as the tray coupling portion 301 is inserted into the tray attachment portion 314.

On the other hand, the second rotation guide portion 113e is provided with the release preventing protrusion 113f to prevent the rotation ring 310 from being detached from the second rotation guide portion 113e. The upper end of the separation preventing protrusion 113f may be hooked so as to be hooked on the upper surface of the inner ring part 312. [ Therefore, when the tray 300 is rotated, the rotation ring 310 can be prevented from moving away from the second rotation guide portion 113e as the rotation ring 310 is lifted upward, Can be stably maintained.

In addition, a support portion 321 for supporting a lower surface of the tray cover 330 may be provided in the tray body 320.

A depression 322 is formed on the bottom surface of the tray body 320. The depressed portion 322 protrudes downward from the bottom surface of the tray body 320 and supports the bottom surface of the tray 300 in contact with the ground on which the water purifier 10 is installed. Accordingly, the tray 300 can be supported at a predetermined height without sagging at the surface of the water purifier 10 installed when the tray 300 rotates in the left and right directions.

The depression 322 may be formed to be equal to or larger than the size of the floater 340 so that the floater 340 can be accommodated. Therefore, the plotter 340 can be disposed inside the depression 322 to be movable up and down according to the water level.

The plotter 340 may include a floating unit 341, an indicator 342, and a cap 343. [ The floating portion 341 may be formed of a material that can be accommodated inside the depression 322 and floated in water by buoyancy.

The indicator 342 may be disposed at the upper end of the floating unit 341 and fixed to the floating unit 341 by the cap 343. The indicator 342 is formed in a ring shape and may be formed in a different color from the floating portion 341, the cap 343, and the tray cover 330.

The cap 343 forms the upper end of the plotter 340 and forms a portion exposed to the tray cover 330. The cap 343 may be formed of an exposed portion 343a exposed through the tray cover 330 and a penetrating portion 343b extending downward from the exposed portion 343a. The exposed portion 343a may have the same shape as the diameter of the indicator 342. The penetrating portion 343b may be inserted into the upper end of the floating portion 341 through the indicator 342. [

The upper surface of the cap 343 may be located on the same plane as the upper surface of the tray cover 330 or may be located further downward when the tray 300 is not filled with water. When the tray 300 is filled with a predetermined amount of water or a full water level, the floating portion 341 is lifted by buoyant force and the cap 343 is further protruded from the upper surface of the tray cover 330 .

At this time, when the floating portion 341 is completely lifted as shown in FIG. 14, the indicator 342 protrudes further upward than the upper surface of the tray cover 330. Accordingly, when the color of the indicator 342 is identified, the user can recognize the full water level, and the user can separate the tray 300 and empty the stored water.

A concave portion 323 is formed in a circular arc shape on the rear surface of the tray body 320 and the rear end of the tray cover 330 so that the concave portion 323 surrounds a part of the rotating ring 310 So that the rear end of the tray 300 can be brought into close contact with the rotation ring 310.

In addition, protrusions 325 protrude rearward from both sides of the rear end of the tray body 320. The outer surface of the protrusion 325 extends in the same plane from one side of the tray body 320 so as to cover the connection portion between the tray 300 and the rotary ring 310.

Particularly, when the tray 300 is rotated, the outer appearance of the water purifier can be formed in a shape extending from the front surface of the water purifier formed in a round shape. Accordingly, the appearance can be kept beautiful regardless of whether the tray 300 is rotated or not.

The tray coupling part 301 is protruded rearward at the center of the concave part 323 of the tray body 320 for coupling the tray 300 and the rotary ring 310. [ The tray coupling part 301 may be inserted into the tray mounting part 314 when the tray 300 is mounted.

A plurality of slits 331 are formed in the tray cover 330 so that the remaining amount of the slit 331 can be introduced into the storage space of the tray body 320 through the slit 331, So that it can be prevented from being protruded to the outside.

An indi gating hole 332 is further formed in the tray cover 330. The indigating hole 332 is formed at a position corresponding to the position of the cap 343 of the floater 340 and may be formed to have the same size as the cap 343. Therefore, when the floater 340 is moved up and down, the cap 343 is moved up and down through the indi gating hole 332. When the tray 300 is full, the indicator 342 is exposed to the outside of the indi gating hole 332 to display the full number status to the user.

The tray cover 330 may further include a collecting hole 333. The water collection hole (333) is opened vertically below the water outlet nozzle (280). Therefore, the water dropped when the water is taken out in a state in which the container such as cup is not placed in the tray 300 can be collected directly into the tray 300 through the water collecting hole 333.

Hereinafter, the water extraction process of the water purifier according to the embodiment of the present invention will be described.

18 is a circuit diagram schematically showing a flow path of water of the water purifier. 19 is a block diagram showing the flow of the control signal of the water purifier.

As shown in the drawing, the water inlet pipe 191 of the water purifier 10 is connected to the water supply to receive raw water. The water inlet pipe 191 is connected to the pressure reducing valve 192 and the raw water passing through the pressure reducing valve 192 is depressurized to a pressure set for the operation of the water purifier 10.

The depressurized raw water flows toward the filter 120 along the pipe connecting the pressure reducing valve 192 and the filter 120. The raw water passing through the filter 120 is removed from the raw water to be purified. By the opening of the water supply valve 193, the purified water passes through the water supply valve 193 along the pipe and then the flow rate sensor 194 in order.

The water supply valve 193 and the flow rate sensor 194 may be connected to the main PCB 510 and the opening degree of the water supply valve 193 may be adjusted according to a signal transmitted from the main PCB 510 do. The flow rate sensed by the flow sensor 194 is transmitted to the main PCB 510 and used as data necessary for controlling the water purifier.

The constant passing through the flow sensor 194 may be branched into the cold water side 195a and the hot water side 195b through the branch pipe 195.

The purified water flowing into the piping of the cold water side 195a is branched into the cold water side 196a and the purified water side 196b again by the T connector 196 and flows through the cold water outlet valve 197 and the water outlet valve 198, Lt; / RTI > The water outlet valve 198 and the cold water outlet valve 197 may be connected to the main PCB 510 to be opened or closed. That is, the water outlet valve 198 and the cold water outlet valve 197 can be selected according to the setting of the user, and the selected valve can be opened through the operation of the water outlet button 420 to take out the water.

On the other hand, the water passing through the cold water outlet valve 197 passes through the cooling coil inside the cooling tank 150. The water flowing along the cooling coil is cooled by heat exchange with the cooling water in the cooling tank 150, and the cooling water is cooled to maintain the set temperature.

The compressor 141 connected to the main PCB 510 is driven to cool the cooling water. The operation of the compressor 141 may be determined by a cold water temperature sensor 152 provided in the cooling tank 150. Therefore, the cooling water can always maintain the set temperature, and the driving of the compressor 141 can be controlled for this purpose. The compressor (141) is controlled in frequency in response to the load required by the inverter compressor, and the cooling capacity can be adjusted. That is, the compressor 141 can be driven by the inverter control, and the cooling water can be cooled at the optimum efficiency.

Meanwhile, the compressor 141 may be operated by the user to operate the operation unit 410 to set the operation to the forced OFF state. The compressor 141 can be kept in the OFF state at the time when the cold water consumption is low or the power saving is required or when the use of the cold water is not desired.

In addition, the main PCB 510 controls the driving of the cooling fan 143 as well as the compressor 141. Also, the main PCB 510 controls the driving of the agitator motor 153 provided inside the cooling tank 150. The motor 153 is driven by the main PCB 510 to increase the heat exchange efficiency between the cooling water and the cold water passing through the cooling coil. By driving the motor 153, the agitator is rotated, and the cooling water can be forcedly convected inside the cooling tank 150, and as a result, the purified water inside the cooling coil effectively cools.

The cold water passing through the cooling tank 150 flows into the water outlet pipe 182 through the T connector 181 and the cold water passing through the water outlet pipe 182 can be taken out through the water outlet nozzle 280 .

When the water outflow valve 198 is opened, the purified water passing through the water outflow valve 198 flows into the water outflow pipe 182 through the T connector 181, And then can be taken out to the outside through the outflow nozzle 280.

On the other hand, when the user selects the extraction of hot water, the constant can flow to the hot water side 195b of the branch pipe 195. The flow control valve 199 is opened by the control of the main PCB 510 and the water flowing through the flow control valve 199 is adjusted to a flow rate suitable for heating the hot water. That is, the amount of purified water supplied to the hot water tank 161 is controlled so that water can be heated to a predetermined temperature by the induction heating assembly 160.

The purified water passing through the flow control valve 199 passes through the hot water tank 161. In the course of passing through the hot water tank 161, it can be heated to a predetermined temperature. The hot water tank 161 can be heated by an induction heating method. For this purpose, the output of the magnetic force of the working coil can be controlled by controlling the induction heating consuming frequency 520.

In order to drive the induction heating assembly 160, a high voltage is required compared to the main PCB 510, and power is supplied from the power supply PCB 530 connected to the power line for supplying the high voltage. The power supply PCB 530 supplies appropriate power according to whether the induction heating assembly 160 is driven or not, and supplies power suitable for the main PCB 510.

By driving the induction heating assembly 160, water in the hot water tank 161 can be heated to a predetermined temperature. The hot water outlet valve 183 may be equipped with a hot water temperature sensor. The hot water temperature sensor senses the temperature of the hot water flowing through the hot water tank 161 and transmits the sensed temperature to the main PCB 510. In the main PCB 510, the output of the working coil can be adjusted based on the input hot water temperature data.

The temperature of the hot water tank 161 itself may be sensed by a tank temperature sensor 162 provided outside the hot water tank 161. If the tank temperature sensor 161 is raised to a temperature higher than the set temperature and there is a possibility of a fire, the fuse 184 may be short-circuited by transmitting a signal to the main PCB 510. An overload protection (OLP) 147 may be connected to the main PCB 510. The overpipe 147 cuts off power supply to the compressor 141 when the compressor 141 is overloaded, .

When the fuse 184 is short-circuited by an abnormal operation of the induction heating assembly 160, the power supplied from the power supply PCB 530 to the induction heating PCB 520 is cut off and the induction heating assembly 160 Is prevented from being overheated and damaged.

The hot water heated by passing through the hot water tank 161 by the hot water outlet valve 183 flows to the outflow nozzle 280 through the hot water pipe 185 and can be taken out to the outside.

On the other hand, when the water is taken out by the operation of the head-up button 420, the LED of the operation unit 410 can be turned on under the control of the operation unit's user's bill 411.

The operation unit 410 may include a hot water button, a constant button, and a cold water button. At this time, the temperature of the hot button can be set. Also, a capacity selection button for setting an outflow capacity and a continuous button for selecting a continuous outflow may also be provided. Further, a lock button for temporarily interrupting the operation of the operation unit 410 may also be provided.

The operation portion of the filter unit 411 can be switched between the state of the filter 120 and the state of the filter 120 through the lighting color of the switch LED 412 irradiated through the water- It is also possible to recognize the period.

In addition, the operation state or the operation state of the water purifier 10 can be transmitted to a terminal such as a user's cellular phone through the NIFF scheme 430 and displayed. Further, the information and operation signal may be transmitted to the INF / FPC 430 through the terminal, and the water purifier 10 may be driven using the transmitted information.

For example, the user can confirm information such as the life of the filter 120 and the usage pattern of the water purifier 10 through an application installed in the mobile phone, and a power saving mode for turning off the cold water mode of the water purifier 10 And other operations of the water purifier 10 can be set.

Meanwhile, during use of the water purifier 10, the cooling water in the cooling tank 150 may be drained and filled with new cooling water.
