Particularly, the rotary pipe 264 is made of stainless steel, so that repeated rotation due to rotation of the rotator 21 and breakage or deformation of the collet of the metal material can be prevented.

On the other hand, the hot water pipe 262 connected to the hot water tank 71 and supplied with hot water can be directly connected to the outflow nozzle 25 without going through the water outlet 20. Therefore, when the hot water is taken out, the water in the hot water tank 71 can be taken out immediately, and the quality of the hot water is improved. That is, in the case of using a common flow path with cold water or purified water, there is a problem that hot water firstly taken out by cold water or purified water remaining on the flow path when hot water is taken out can not satisfy the temperature. However, when the separate hot water pipe 262 is connected to the water outlet nozzle, the hot water in the hot water tank 71 can be supplied to the water outlet nozzle 25 without loss of temperature.

The coupling rings 236 and 246 may have circular coupling holes formed therein, and a pair of coupling rings 236 and 246 may be provided on both sides. A pair of the coupling rings 236 and 246 disposed on both sides may be symmetrically arranged with respect to a center line passing through the rotation axis of the rotator 21 in the radial direction. The coupling rings 236 and 246 may be formed on both the upper guide bracket 23 and the lower guide bracket 24 or only on the upper guide bracket 23.

The coupling rings 236 and 246 can be engaged with the rotation connection part 421 on the bottom surface of the operation part 40. [ In detail, a pair of the rotation connection portions 421 can be inserted through the coupling rings 236 and 246, so that the operation portion 40 can be rotated together when the rotator 21 rotates.

The takeout button 41 and the water outlet 20 are also rotated when the operation unit 40 and the rotator 21 are rotated together by the combination of the operation unit 40 and the rotator 21. [ Accordingly, since the take-out button 41 and the outflow nozzle 25 are positioned and rotated in the same line, the positions of the take-out button 41 and the outflow nozzle 25 do not need to be adjusted separately, thereby improving the operability of the user.

Meanwhile, an oil damper 27 may be provided on the bottom of the rotator 21, that is, the lower guide bracket 24. The oil damper 27 smoothly rotates without feeling the hitting of the rotator 21 when the water outlet 20 rotates and the rotator 21 rotates at a constant speed .

The oil damper 27 is a general structure used to keep the rotational speed constant, and a detailed description thereof will be omitted. A pinion gear 271 is coupled to the rotation shaft of the oil damper 27 and the pinion gear 271 is disposed so as to move along the internal gear 331 formed at the upper end of the filter bracket 30 do.

The pinion gear 271 has a circular shape with a radius of curvature much smaller than the radius of curvature of the internal gear 331, and the number of teeth is also small. When the rotator 21 is mounted on the upper end of the filter bracket 30, the pinion gear 271 is positioned on the inner surface of the internal gear 331 and engaged with the internal gear 331.

15 is a partial perspective view of the filter bracket of the water purifier. 16 is a cross-sectional view showing the coupling structure of the rotator.

As shown in the figure, an internal gear 331 is formed at the upper end of the filter bracket 30. The internal gear 331 may be formed with a predetermined curvature at an upper end of the rotator mounting portion 33. The internal gear 331 is spaced apart from the first rotation guide rail 332 in the radial direction. The internal gear 331 is located adjacent to the upper end outer edge of the filter bracket 30 and may be disposed concentrically with the first rotation guide rail 332. Therefore, when the rotator 21 is mounted, the internal gear 331 may be configured to engage with the pinion gear 271.

On the other hand, the rear surface of the filter bracket 30 is opened rearward and the rear end of the filter bracket 30 is coupled to the front end portion of the side panel 15. The first rotation guide rail 332 is provided on the upper end of the filter bracket 30 so that the rotator 21 is rotatably mounted in the left and right direction.

The first rotation guide rail 332 may have a semicircular curvature to guide the rotation of the rotator 21. The first rotation guide rail 332 may be fixed to the inside of the upper end of the filter bracket 30.

Further, a second rotation guide rail 1111 protruding from the inner circumferential surface of the upper cover 111 may be further provided. The second rotation guide rail 1111 is positioned above the first rotation guide rail 332 and has the same shape to guide the rotation of the rotator 21.

The first rotation guide rail 332 and the second rotation guide rail 1111 are spaced apart from each other in the vertical direction with the rotator 21 interposed therebetween. The upper and lower ends of the rotator 21 are engaged with the first and second rotation guide rails 332 and 1111 to guide the rotation of the rotator 21 by the mounting of the rotator 21 do.

The rotator 21 is a component for horizontally rotating the water outlet 20 to the left or right. The rotator 21 has rotation guide projections 233 and 243 formed at a central portion thereof with a constant curvature at a central portion thereof and is slidable along the rotation guide rails 332 and 1111 using the rotation guide projections 233 and 243 Lt; / RTI >

There is a difference in that the rotation guide projections 233 and 243 are provided in the rotator 21 and the rotation guide rails 332 and 1111 are provided in the filter bracket 30 and the upper cover 111. However, The rotation guide rails 233 and 243 and the rotation guide rails 332 and 1111 have the same curvature and are engaged with each other to guide the rotation of the rotator 21.

For example, the rotation guide projections 233 and 243 include a lower rotation guide projection 243 protruding downward from the lower rail receiving groove 242 of the lower guide bracket 24, And an upper rotation guide protrusion 233 protruded upward from the upper rail receiving groove 232 of the upper rail receiving groove 232.

The ends of the rotation guide projections 233 and 243 are hook-shaped. The inner circumferential surfaces of the ends of the rotation guide projections 233 and 243 when the rotation guide projections 233 and 243 are engaged with the rotation guide rails 332 and 1111 face each other with a part of the rotation guide rails 332 and 1111, .

The rotation guide projections 233 and 243 are formed at the same curvature as the rotation guide rails 332 and 1111 and are slidably coupled to the rotation guide rails 332 and 1111 in the rotation direction. When the rotation guide projections 233 and 243 and the rotation guide rails 332 and 1111 are engaged with each other, the rotation guide rails 332 and 1111 are received in the rail receiving grooves 232 and 242 formed inside the rotation guide projections 233 and 243 One side of the rail receiving grooves 232 and 242 and the rotation guide rails 332 and 1111 are overlapped in the thickness direction and the end portions of the rotation guide projections 233 and 243 are hooked to overlap with the rotation guide rails 332 and 1111 in the thickness direction Lt; / RTI >

According to such a coupling structure, the water outlet 20 can be stably rotated, and the position of the water outlet nozzle 25 can be freely changed without separating the water outlet 20. In this case, it is not necessary to separately form a rotation shaft at the center of the rotator 21.

For example, when the rotator 21 is rotated by holding the water head 20 in the structure in which the water head 20 protrudes forward from one side of the rotator 21, due to the eccentric load of the water head 20 It is possible to solve the problem that the heading portion 20 is lifted up or down and the rotation of the heading portion 20 and the rotator 21 becomes unstable. Further, the hook shape of the rotation guide projections 233 and 243 can prevent the rotator 21 from being detached.

Since the contact area between the rotation guide projections 233 and 243 and the rotation guide rails 332 and 1111 during rotation of the rotator 21 is wide, the eccentric load can be dispersed when the rotatable body 21 is rotated by holding the water- It is possible to reduce damage such as abrasion and scratches due to friction.

The rotation guide projections 233 and 243 formed on the upper guide bracket 23 and the lower guide bracket 24 may be made of different materials from the rotation guide rails 332 and 1111. More preferably, the rotation guide projections 233 and 243 can be formed of engineering plastic (POM) having excellent fatigue resistance, toughness, abrasion resistance, and the like. Therefore, when the rotation guide projections 233 and 243 rotate along the rotation guide rails 332 and 1111, wear and noise due to friction between the rotation guide projections 233 and 243 and the rotation guide rails 332 and 1111 can be reduced.

The flow rate control valve 368 can control the temperature of the water passing through the hot water tank 71 to a predetermined temperature or higher do.

In detail, when the amount of water passing through the hot water tank 71 is excessively large, it is not possible to efficiently heat the water passing through the hot water tank 71 at a high speed. In such a situation, Things can happen.

Therefore, when hot water is to be taken out, the amount of water supplied to the hot water tank 71 may be adjusted to heat the water. Further, even when the temperature of the water to be supplied is too low, the amount of water to be introduced may be reduced to improve the heating performance in the hot water tank 71.

A mica sheet 75 is provided on the front and rear surfaces of the working coil 72. The mica sheet 75 corresponds to the front and rear shapes of the working coil 72 and shields the entire front and rear surfaces of the working coil 72.

The mica sheet 75 has a predetermined thickness. Accordingly, the hot water tank 71 and the ferrite core 74 maintain the working coil 72 at a predetermined interval, so that the hot water tank 71 is effectively heated by the magnetic force lines formed by the working coil 72 . Of course, the mica sheet 75 may be provided on only one of the front surface and the rear surface of the working coil 72, if necessary.

The core fixing portions 734 and 735 may be radially formed as a plurality of ferrite cores 74.

The hot water tank 71 is mounted on the rear surface of the heating bracket. The hot water tank 71 is configured to generate heat by being affected by a magnetic force line formed by the working coil 72. Therefore, the purified water is heated while passing through the inner space of the hot water tank 71 to become hot water.

The overall shape of the hot water tank 71 may be flat and compact. The hot water tank 71 is formed so as to correspond to the overall shape of the induction heating assembly 70 so that the induction heating assembly 70 is installed between the filter bracket 30 and the cooling tank 60 in the water purifier 1. [ So that it can be accommodated in the space. In addition, the hot water tank 71 is formed to have a large area so that the heating area can be sufficiently secured and instantaneous heating becomes possible.

The hot water tank 71 is formed by bonding a first cover 711 having a planar shape and a second cover 712 having a concavo-convex shape to each other. An output tube 713 for discharging heated water is formed at the upper end of the hot water tank 71 and an input tube 714 for supplying water for heating is formed at the lower end of the hot water tank 71. The output tube 713 extends laterally to have an upward slope and the input tube 714 extends laterally to have a downward slope. Therefore, the connection space of the piping connected to the hot water tank 71 is ensured and the flow of water is facilitated.

A T connector 715 is connected to the output tube 713. A hot water pipe 262 connected to the hot water outlet valve 369 is connected to one side of the T connector 715 facing the output pipe 713. A safety valve 716 is provided in a direction crossing the other side of the T connector 715, that is, the output tube 713, that is, toward the bottom surface of the water purifier 1.

The safety valve 716 discharges steam generated when the hot water is heated in the hot water tank 71 and prevents the pressure in the hot water tank 71 from being excessively increased due to the steam . The safety valve 716 is configured to be opened at a predetermined pressure and may have various structures in which the steam discharge in the hot water tank 71 can be smoothly performed.

An outlet of the safety valve 716 faces the bottom surface of the water purifier 1 and a silicone hose and an additional steam pipe 7161 are connected to the outlet of the safety valve 716. The steam pipe 7161 connected to the safety valve 716 extends to the outside of the water purifier 1 along the base 13. Therefore, when the water purifier 1 is installed, the steam pipe 7161 can be taken out into a separate sink or a drain to allow water generated by steam or steam to be drained.

A T connector 717 is also connected to the input tube 714 and an end cap 7171 is provided at one side of the T connector 717 to shield the opening of one side of the T connector 717. A check valve 718 may be provided on one side of the T connector 717 which opens downward. The check valve 718 is for supplying an integer to the input tube 714 and is formed to be openable in the supply direction. Therefore, when the end cap 7171 is removed in a state where the check valve 718 is closed, water in the hot water tank can be discharged through the input pipe 714.

In more detail, the water purifier 1 is filled with water to test the heating performance of the hot water tank 71 before shipment. After completion of the test, the water in the hot water tank 71 is completely drained and shipped.

Accordingly, the end cap 7171 is opened to fully empty the water in the hot water tank 71 when the hot water tank 71 is shipped after the test. At this time, the check valve 718 is closed, and the end cap 7171 has a structure for shielding the opening of the T connector 717 connected to the input tube 714 at the lower end of the hot water tank 71. Because of this structure, the water in the hot water tank 71 can be discharged by its own weight when the end cap 7171 is opened.

Of course, the end cap 7171 may be constituted by a valve that can be opened and closed, not by a structure of a simple cap, and may be configured to empty water in the hot water tank 71 by operating a valve.

As shown in the drawing, the hot water tank 71 is formed by joining the rims of the first cover 711 and the second cover 712 to each other. The rim of the first cover 711 and the rim of the second cover 712 may be joined to each other by welding or the like so as to maintain airtightness.

The first cover 711 has a flat plate shape so as to generate heat under the influence of a magnetic force line formed by the working coil 72. The first cover 711 may be made of a suitable material for heat generation. The first cover 711 may be made of a stainless steel material, preferably four stainless steel materials. More preferably, the first cover 711 may be made of stainless steel (STS) 439 material.

Since the second cover 712 is disposed on the opposite side of the working coil 72 with respect to the first cover 711 and the influence of the magnetic force lines is small, the second cover 712 is less related to the heat generation than the first cover 711. Therefore, it is preferable that the second cover 712 is made of a material having a corrosion resistance characteristic rather than a heat generation characteristic. An output tube 713 and an input tube 714 are provided at the center of the upper and lower ends of the second cover 712. The output tube 713 and the input tube 714 may extend in opposite directions.

The second cover 712 includes a base surface 7121 and a protrusion 7122. The base surface 7121 and the protrusion 7122 can be integrally formed by press working. When the second cover 712 having the base surface 7121 is partially pressed, the protrusion 7122 can be formed in the second cover 712.

The base surface 7121 faces the first cover 711 at a position spaced from the first cover 711 and is spaced apart from the first cover 711 to form an internal space of the hot water tank 71 . The protrusion 7122 protrudes from the base surface 7121 toward the first cover 711. When the first cover 711 and the second cover 712 are joined to each other, And may be formed so as to be in contact with or adjacent to the cover 711. The circumference of the protrusion 7122 may be inclined.

The protrusion 7122 is positioned between the input tube 714 and the output tube 713 and a plurality of protrusions 7122 are formed to disperse the flow of water flowing into the input tube 714 and discharged to the output tube 713, The residence time in the hot water tank 71 can be extended.

The protrusion 7122 may include a transverse protrusion 7124 and a vertical protrusion 7123. The longitudinal protrusion 7123 may extend in the same direction as the longitudinal direction of the hot water tank 71. The transverse protrusion 7124 is formed at both ends of the longitudinal protrusion 7123 and extends to have a predetermined length.

A plurality of the protrusions 7122 may be arranged at regular intervals, preferably one at the center, and a plurality of protrusions 7122 may be formed on the opposite sides of the protrusions 7122. Although the embodiment of the present invention has been described by way of example in which three are formed, the number of the three is not limited.

Accordingly, the water flowing into the input tube 714 is scattered by colliding with the transverse protrusion 7124 below, flows along the transverse protrusion 7123, and then bumps against the transverse protrusion 7124, And then discharged to the output tube 713. [ And this action occurs simultaneously in the plurality of protrusions 7122. [

In this process, the water flowing inside the hot water tank 71 is dispersed, so that the residence time in the hot water tank 71 becomes long and can be further heated. Then, the water is uniformly spread over the entire inside of the hot water tank 71, so that water can be heated more efficiently.

At least one protrusion 7122 of the plurality of protrusions 7122 is formed with a weld 7125. The welded portion 7125 is protruded toward the first cover like the protrusion 7122. The position of the welded portion 7125 may be formed at a central portion of the hot water tank 71. The welded portion 7125 and the first cover 711 can be joined to each other by welding.

The projecting portions 7122 other than the welded portion 7125 are not engaged with the first cover 711 by welding but are in contact with or adjacent to the first cover 711, And is in a state of being engaged with the first cover 711.

Therefore, the first cover 711 and the second cover 712 maintain the shape of the hot water tank 71 without being deformed or damaged even when the pressure inside the hot water tank 71 is raised during hot water heating, So that the combined state can be maintained.

The refrigerant passing through the evaporator (63) cools the cooling water stored in the inner case (611).

When the temperature of the cooling water measured by the cold water temperature sensor 601 is lower than the second reference temperature, the refrigeration cycle of the water purifier 1 is stopped. The second reference temperature is lower than the first reference temperature. The first reference temperature and the second reference temperature serve as a reference for the operation and stoppage of the refrigeration cycle, respectively. Therefore, the cooling water stored in the inner case 611 can be maintained between the first reference temperature and the second reference temperature by the temperature measurement by the cold water temperature sensor 601 and the operation of the refrigeration cycle.

A mounting portion 134 to which the compressor 51 is mounted is formed at the center of the base 13. The mounting portion 134 may protrude upward to support the compressor 51. Four mounting portions 134 may be provided to support four corners of the bottom surface of the compressor 51. A nut is inserted and inserted into the mounting portion 134. The compressor 51 is fixed by fastening a screw at the bottom of the mounting portion 134 after the compressor 51 is seated.

At the center of the base 13, a suction grill 135 is further formed. At least a portion of the suction grill 135 may be positioned between the mounting portions 134 and may be positioned below the compressor 51. Therefore, the air sucked into the water purifier 1 can cool the compressor 51 via the compressor 51. The suction grill 135 is formed in the lattice shape, and a plurality of suction ports are formed to prevent foreign substances from entering the suction grill 135.

A condenser bracket 54, in which the condenser 52 is accommodated, is disposed behind the suction grill 135. The condenser bracket 54 is located at the rear half of the base 13. The condenser bracket 54 may include a condenser mounting portion 541 fixed to the base 13 and a tank mounting portion 542 positioned above the condenser mounting portion 541.

A cooling fan 53 is installed on the front surface of the condenser mounting portion 541.

38 is an exploded perspective view showing a coupling structure of the tray of the water purifier. FIG. 39 is a view showing the state of the full-water level of the tray.

As shown in the drawing, the tray 90 includes a tray body 92 having a storage space therein, and a tray cover 93 detachably coupled to cover an upper portion of the tray body 92 .

A storage space is formed in the tray body 92 so as to be depressed in a downward direction, so that residual water is stored therein. The edge of the tray body 92 may be configured so as to surround the edge of the tray cover 93. A support portion 921 for supporting the lower surface of the tray cover 93 may be provided in the tray body 92.

A depression 922 is formed on the bottom surface of the tray body 92. The depressed portion 922 protrudes downward from the bottom surface of the tray body 92 and supports the bottom surface of the tray 90 in contact with the ground on which the water purifier 1 is installed. Therefore, the tray 90 can be supported at a constant height without sagging at the surface of the water purifier 1 when the tray 90 rotates in the left-right direction.

The depression 922 may be formed to be equal to or larger than the size of the plotter 94 so that the plotter 94 can be accommodated. Therefore, the plotter 94 can be disposed inside the depression 922 so as to be movable up and down according to the water level.

The plotter 94 may include a floating portion 941, an indicator 942, and a cap 943. [ The floating portion 941 may be formed of a material that can be accommodated inside the depression 922 and floated in water by buoyancy.

The indicator 942 may be disposed at the upper end of the floating portion 941 and fixed to the floating portion 941 by the cap 943. The indicator 942 is formed in a ring shape and may be formed in a different color from the floating portion 941, the cap 943, and the tray cover 93.

The cap 943 forms the upper end of the plotter 94 and forms a portion exposed to the tray cover 93. The cap 943 may include an exposed portion 9431 exposed through the tray cover 93 and a penetrating portion 9432 extending downward from the exposed portion 9431. The exposed portion 9431 may have the same shape as the diameter of the indicator 942. The penetrating portion 9432 may be inserted into the upper end of the plotter 94 through the indicator 942.

The upper surface of the cap 943 is located on the same plane as the upper surface of the tray cover 93 or is located further downward. The float 941 is raised by buoyancy when the tray 90 is filled with water or the water level is higher than a predetermined level and the cap 943 is further protruded from the upper surface of the tray cover 93 .

39, the indicator 942 protrudes further upward than the upper surface of the tray cover 93 when the floating portion 941 is completely raised. Accordingly, when the color of the indicator 942 is identified, the user can recognize the full water level, and the user can separate the tray 90 and empty the stored water.

A concave portion 923 is formed in a circular arc shape on the rear surface of the tray body 92 and the rear end of the tray cover 93 so that the concave portion 923 surrounds a part of the rotary ring 91 And the rear end of the tray can be brought into close contact with the rotary ring.

On both sides of the rear end of the tray body 92, a projecting portion 95 protrudes rearward. The outer surface of the projecting portion 95 extends in the same plane from one side of the tray body 92 so as to cover the connection portion between the tray 90 and the rotary ring 91.

In particular, when the tray 90 is rotated, the outer appearance of the water purifier can be formed in a shape extending from the front surface of the water purifier. Therefore, the appearance of the tray 90 can be enhanced regardless of whether the tray 90 is rotated or not.

The tray engaging portion 96 protrudes rearward at the center of the concave portion of the tray body 92 for engaging the tray 90 and the rotary ring 91. The tray coupling portion 96 may be inserted into the tray mounting portion 914 when the tray 90 is mounted.

A plurality of slits 931 are formed in the tray cover 93 so that the remaining amount can be introduced into the storage space of the tray body 92 through the slits 931, So that it can be prevented from being protruded to the outside.

An indi gating hole 932 is further formed in the tray cover 93. The indigating hole 932 is formed at a position corresponding to the position of the cap 943 of the floater 94 and may be formed to have the same size as the cap 943. Therefore, when the floater 94 is moved up and down, the cap 943 is moved up and down through the indi gating hole 932. When the tray 90 is fully populated, the indicator 942 is exposed to the outside of the indi gating hole 932 to display the full number status to the user.

A collecting hole 933 may be further formed in the tray cover 93. The water collection hole (933) is opened vertically below the water outlet nozzle (25). Therefore, when the water is taken out from the tray 90 without a container such as a cup, water falling down through the water collecting hole 933 is directly collected in the tray 90.

40 is an exploded perspective view showing a coupling structure of a condenser bracket, a blowing fan, and a condenser of the water purifier. 41 is an exploded perspective view showing cooling air flow of the water purifier.

As shown in the drawing, the condenser bracket 54 may have the condenser mounting portion 541 formed at a lower portion thereof, and the tank mounting portion 542 may be formed at an upper portion thereof.

A bracket mounting portion 1307 is formed at the lower end of the condenser mounting portion 541. The bracket mounting portion is supported on the base, and a screw is fastened to fix the condenser bracket.

The condenser mounting portion 541 is formed to open the front and rear surfaces and is configured to receive the condenser 52 therein. A condenser support portion 921 protruding upward is formed on the inner bottom surface of the condenser mounting portion 541. The condenser 52 is supported by the condenser support portion 921 so as to be spaced apart from the bottom of the condenser mounting portion, thereby facilitating the flow of cooling air and promoting heat exchange.

The condenser 52 is formed by bending a plate-shaped tube 521 a plurality of times, and a heat exchange plate 522 formed by bending continuously is disposed between the plate-shaped tubes. At both ends of the tube 521, a header 523 communicating with a plurality of tubes 521 is provided. A refrigerant pipe connected to the compressor 51 and the evaporator 63 may be connected to the header 523 so that the refrigerant circulates in the refrigeration cycle. Accordingly, the condenser 52 is formed in a generally hexahedral shape, and can be formed in the compact size to be accommodated in the condenser mounting portion 541.

A fixing hole 5411 for inserting the fixing member 543 for mounting the cooling fan 53 may be formed on the front surface of the condenser mounting portion 541. The fixing holes 5411 are formed at the four corners of the front surface of the condenser mounting portion 541 and the fixing members 543 fix the four corners of the cooling fan 53.

The fixing member 543 may be formed of an elastic material such as rubber or silicon so as to absorb vibrations when the cooling fan 53 is driven. The fixing member 543 may further include a pair of latching portions 5431 along the periphery of the fixing member 543 so as to be inserted and fixed in the fixing hole 5411. Further, the shape of the latching portion 5431 is formed to be narrower toward the front, so that the fixing member 543 can be easily inserted and removed, and the cooling fan 53 can not be easily detached. The front end of the fixing member 543 is inserted into an insertion hole 531 formed at the corner of the cooling fan 53 so that the cooling fan 53 can be fixed to the front surface of the condenser mounting portion 541.

The tank mounting portion 542 is located above the condenser mounting portion 541 and is formed in a size and shape corresponding to the cross section of the cooling tank 60 so as to accommodate the lower end of the cooling tank 60. The tank mounting portion 542 has a rim 5421 extending upwardly along the circumference and an inner side of the rim 5421 is formed with a predetermined space so that the lower portion of the cooling tank 60 is inserted.

A drain hole 5422 through which the drain valve 69 passes may be formed in the rim 5421. The drain hole 5422 is exposed when the rear cover 12 is removed. Therefore, the drain valve 69 is exposed to the outside, thereby allowing the drainage or filling of the cooling water.

A plate supporting portion 5423 for supporting one end of the support plate 35 may be formed on the front surface of the condenser mounting portion 541, that is, above the cooling fan 53. Accordingly, the support plate 35 can be fixed at both ends to the filter bracket 30 and the condenser bracket 54, thereby providing a mounting space for the heating and control module 50.

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

42 is a circuit diagram schematically showing a flow path of water of the water purifier. FIG. 43 is a block diagram showing the flow of control signals of the water purifier.

As shown in the figure, the water inlet pipe 360 of the water purifier 1 is connected to the water pipe to receive raw water. The water inlet pipe 360 is connected to the pressure reducing valve 133 and the raw water passing through the pressure reducing valve 133 is decompressed to a pressure set for the operation of the water purifier 1. [

Then, the depressurized raw water flows toward the filter 34 side along the pipe connecting the decompression valve 133 and the filter 34. The raw water passing through the filter (34) is removed from the raw water to be purified. By opening the water supply valve 361, the purified water passes through the water supply valve 361 along the pipe, and then passes through the flow rate sensor 363 in order.

The water supply valve 361 and the flow rate sensor 363 may be connected to the main PCB 82 so that the opening degree of the water supply valve 361 may be adjusted according to a signal transmitted from the main PCB. do. The flow rate sensed by the flow sensor 363 is transmitted to the main PCB 82 and used as data necessary for controlling the water purifier.

The constant passing through the flow sensor 363 may be branched into the cold water side 3641 and the hot water side 3642 through the branch pipe 364. [ The purified water flowing into the piping of the cold water side 3641 is branched again to the cold water side 3651 and the purified water side 3652 by the T connector 365 and connected to the cold water outlet valve 366 and the water outlet valve 367 do. The water outlet valve 367 and the cold water outlet valve 366 may be connected to the main PCB 82 to be opened or closed. That is, the water outlet valve 367 and the cold water outlet valve 366 can be selected according to the setting of the user, and the selected valve can be opened by the operation of the take-out button 41, and water can be taken out.

On the other hand, the water passing through the cold water outlet valve 366 passes through the cooling coil 64 inside the cooling tank 60. The water flowing along the cooling coil 64 is cooled by heat exchange with the cooling water in the cooling tank 60, and the cooling water is cooled to maintain the set temperature.

The compressor (51) connected to the main PCB (82) is driven to cool the cooling water. The compressor 51 may be driven by a cold water temperature sensor 601 provided in the cooling tank 60. Therefore, the cooling water can always maintain the set temperature, and the driving of the compressor 51 can be controlled for this. The compressor (51) 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 51 can be driven by inverter control, and the cooling water can be cooled at the optimum efficiency.

On the other hand, the compressor 51 may set the operation to the forced OFF state by operating the operation unit 40 by the user. The compressor 51 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 cold water is not desired.

 In addition, the main PCB 82 controls the driving of the cooling fan 53 as well as the compressor 51. The main PCB 82 controls the driving of the motor 67. The motor 67 is driven by the main PCB 82 to increase the heat exchange efficiency between the cooling water and the cold water passing through the cooling coil 64. The stirrer 68 is rotated by the driving of the motor 67 and the cooling water can be forcedly convected inside the cooling tank 60 to effectively cool the inside of the cooling coil 64 do.

The cold water passing through the cooling tank 60 flows into the water outlet pipe 261 through the T connector 26 and the cold water passing through the water outlet pipe 261 is taken out to the outside through the water outlet nozzle 25 .

When the water outflow valve 367 is opened, the purified water passing through the water outflow valve 367 flows into the water outflow pipe 261 through the T connector 26 and flows through the water out pipe 261 And can be taken out to the outside through the outflow nozzle (25).

On the other hand, if the user selects to take hot water, the constant may flow to the hot water side 3642 of the branch pipe 364. The flow control valve 368 is opened under the control of the main PCB 82 and the water flowing through the flow control valve 368 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 71 is controlled so that water can be heated to a predetermined temperature by the induction heating assembly 70.

The purified water passing through the flow control valve 368 passes through the hot water tank 71. In the course of passing through the hot water tank 71, it can be heated to a set temperature. The hot water tank 71 can be heated by an induction heating method. For this purpose, the output of the magnetic force of the working coil 72 can be controlled by controlling the induction heating consumed energy 84.

In order to drive the induction heating assembly 70, a high voltage is required in comparison with the main PCB 82, and power is supplied from the power supply PCB 86 connected to the power line for supplying the high voltage. The power supply supply ratio 86 supplies appropriate power according to whether the induction heating assembly 70 is driven or not, and also supplies power suitable for the main PCB 82.

By driving the induction heating assembly 70, the water in the hot water tank 71 can be heated to a predetermined temperature. The hot water outlet valve 369 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 71 and transmits the sensed temperature to the main food room 82. In the main PCB 82, the output of the working coil 72 can be adjusted based on the input hot water temperature data.

The temperature of the hot water tank 71 itself may be detected by a hot water temperature sensor 761 provided outside the hot water tank 71. When the hot water temperature sensor 761 is raised to a set temperature or higher and there is a possibility of a fire, the fuse 762 may be short-circuited by transmitting a signal to the main PCB 82. On the other hand, an overload protection (OLP) 511 may be connected to the main PCB, and the off-line 511 may cut off power supply when the compressor 51 is overloaded to protect the compressor 51 do.

When the fuse 762 is short-circuited by an abnormal operation of the induction heating assembly 70, the power supplied from the power supply file ratio 86 to the induction heating cookbook 84 is cut off and the induction heating assembly 70 Is prevented from being overheated and damaged.

The hot water heated by passing through the hot water tank 71 by the hot water outlet valve 369 flows to the outflow nozzle 25 through the hot water pipe 262 and can be taken out to the outside.

On the other hand, when the water is taken out by the operation of the take-out button 41, the LED 2821 of the water outlet 20 can be turned on under the control of the operation portion package 43. The lower part of the water outlet 20 can be illuminated by lighting of the LED.

The operating section personal computer 43 displays the state of the filter 34 through the lighting color of the switch LED 434 irradiated through the take-out button 41 regardless of whether the take-out button 41 is operated or not, Or the exchange period.

In addition, the operation state or the operation state of the water purifier 1 can be transmitted to a terminal such as a user's cellular phone through the NIFF file ratio 88 and displayed. Also, the information and operation signal may be transmitted to the INF / FPC ratio 88 through the terminal, or the water purifier 1 may be driven using the transmitted information.

For example, the user can confirm information such as the life of the filter 34 and the usage pattern of the water purifier 1 through an application installed in the cell phone, and a power saving mode for turning off the cold water mode of the water purifier 1 And other operations of the water purifier 1 can be set.

Meanwhile, during use of the water purifier 1, the cooling water in the cooling tank 60 can be drained and filled with new cooling water.

Hereinafter, the process of replacing the cooling water will be described with reference to the drawings.

44 is a perspective view showing a state in which the water purifier is replaced with a cooling water. 45 is a flowchart sequentially showing the control method of the water purifier.

As shown in the figure, in order to keep the inside of the cooling tank 60 clean, the cooling water in the cooling tank 60 should be exchanged at regular intervals. To this end, the user first exposes the drain valve 69 and then opens the drain valve 69 to discharge the cooling water in the cooling tank 60 to the outside.

The user may connect the drain valve 69 with the service pipe 2 provided separately. The end of the service pipe 2 may be connected to the drain valve 69 in a coupling manner and may have a structure capable of opening the drain valve 69 by connection. Such a structure is the same as that of a general coupling piping, and a detailed description thereof will be omitted.

Meanwhile, after the cooling water in the cooling tank 60 is completely drained, the other end of the service pipe 2 is connected to the outflow nozzle 25. The connection of the service pipe 2 maintains the drain valve 69 open and the outlet nozzle 25 can communicate with the inside of the cooling tank 60.

In this state, the user operates the operation unit 40 to set the mode of the water purifier 1 to the cooling water replacement mode. In the cooling water replacement mode, the control unit (main PCB) is configured to take out the purified water so that the cooling water can be charged when the take-out button 41 is operated, and the predetermined amount of water can be supplied by one operation Respectively. [S110]

 In this state, it is determined whether or not the take-out button 41 is operated. [S120]

If the user does not operate the take-out button 41 for a predetermined time after the user enters the cooling water replacement mode, the operation for replacing the cooling water is not performed, and the main PCB 82 returns to the normal operation mode . [S130]

When the user presses the take-out button 41, the purified water taken out from the outflow nozzle 25 flows into the cooling tank 60 through the service pipe 2, and the operation for filling the coolant again is started . [S140]

In the state where the cooling water replacement mode is set, the water flow sensor 363 senses the flow rate of the purified water supplied by the flow sensor 363. In the main PCB 82, the water outlet valve 367 is controlled do. [S150]

The main PCB 82 senses the sensed value transmitted from the flow sensor 363 and maintains the opening of the water outlet valve 367 until the sensed flow rate reaches a set flow rate. The capacity set in the main PCB 82 is preset to an appropriate capacity to be filled in the cooling tank 60. For example, when the extraction button 41 is operated in the cooling water replacement mode in the main PCB 82, the water outlet valve 367 is opened and the cooling coil 64 and the evaporator 63 are locked An integer of 2.4 L can be supplied to the cooling tank 60. [S160]

When the flow rate sensed by the flow sensor 363 reaches the set flow rate, it is determined that the charging of the cooling water is completed in the main PCB 82 and the water outlet valve 367 is closed. [S170]

After completion of the supply of the water at the set flow rate, the completion of the replacement of the cooling water is displayed through the operation unit 40. At this time, completion of the replacement of the cooling water can be displayed through the color of the light transmitted through the take-out button 41. Of course, completion of the replacement of the cooling water may be output by the buzzer 435, and display of completion of the replacement of the cooling water by using another display means may be possible. [S180]

When the replacement of the cooling water is completed, the user disconnects the service pipe 2 from the drain valve 69 and the water outlet nozzle 25. Then, the control unit cancels the cooling water replacement mode according to automatic or user setting, and is switched to a normal normal operation mode. The normal operation mode is a state in which the hot water chilled water can be discharged by a desired amount through the operation of the take-out button 41. [ [S190]

The upper end of the heating and control module 50 extends to the position of the top cover 14 and can contact with each other. Accordingly, the heating and control module 50 can be efficiently disposed in the space provided in the water purifier 1. [ The induction heating assembly 70 and the control assembly 80 are connected to each other in a state where the heating and control module 50 is completely mounted.

Of course, if the water purifier 1 is a model for extracting pure water and cold water instead of a model for extracting hot water, only the control assembly 80 may be mounted on the support plate 35. In addition, the control assembly 80 in which the corresponding bill is assembled according to the option function can be mounted. [STEP 5]

Next, the rotator (21) is mounted on the upper end of the filter bracket (30). An upper guide bracket 23 and a lower guide bracket 24 are assembled to the rotator housing 22 and a water outlet pipe 261 is disposed inside the rotator housing 21 .

The rotator 21 is mounted on the rotator mount 33 of the filter bracket 30 and rotatably mounted thereon. The pinion gear 271 of the rotator 21 is engaged with an internal gear 331 at the upper end of the filter bracket 30 so that the pinion gear 271 rotates when the rotator 20 rotates. And moves along the internal gear 331 to make the rotation speed of the rotator 21 constant.

After the rotator 21 is mounted, the water pipe 261 and the T connector 26 connected to the cold water and the purified water pipe are fitted together. The end of the water pipe 261 is connected to the water outlet nozzle 25. Also, the hot water pipe 262 is connected to the water outlet nozzle 25 to complete connection of the pipe.

The upper cover 111 is coupled to the upper end of the rotator 21. Therefore, the rotator 21 can be provided with a structure capable of stable rotation by completing the vertical coupling. [STEP 6]

Next, the top cover 14 is assembled. The top cover 14 may be formed to be seated on the upper surface of the upper cover 111 and the cooling tank 60 in a state in which the operating portion 40 is rotatably mounted.

A rotation connection portion 421 extending from the front surface of the operation portion 40 is inserted into the coupling rings 236 and 246 of the rotator 21 when the top cover 14 is mounted, So that they can rotate together.

In addition, the main body portion 82 of the control assembly 80 and the main body portion 43 of the operation portion are connected to each other through a connector, and power and signals can be transmitted.

In this state, a filter for testing can be mounted on the filter socket of the filter bracket 30, and a test is performed after connection of the filter. After the completion of the test, the filter for inspection is removed, and the filter 34 is assembled to the filter socket after removing the remaining water of the flow path.

Then, water is injected into the hot water tank 71 and the induction heating assembly 70 is operated to test hot water heating. After completion of the test, the end cap 7171 is removed, the residual water in the hot water tank 71 is completely drained, and then the end cap 7171 is mounted again. [STEP 7]

Next, the rear cover 12 is screwed and fixed to the base 13, and then the side panel 15 is screwed and fixed to both sides of the base 13. At this time, the side panel 15 may be coupled to the top cover 14 by a screw. [STEP 8]

Then, the lower cover 112 is coupled to the side panel 15 and the rotator 21 to complete the assembly of the water purifier 1. The tray 90 separately assembled with the loafer may be packaged and shipped together. When the user installs and uses the tray 90, the tray 90 is coupled to the rotary ring 91 and used. [STEP 9]
