Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

Embodiments of the present invention relate to a water purifier, i.e., a water purifier for purifying raw water such as tap water to supply drinking water. Drinking water may include hot water, cold water or an integer at ambient temperature. Accordingly, such water purifiers may include an apparatus for supplying a beverage such as coffee using an integer, and may also include an apparatus for generating and supplying ice using purified water.

1 shows an example of a water purifier according to an embodiment of the present invention. As shown, the external structure or shape of the water purifier may be similar or identical to a conventional water purifier.

The water purifier 100 may include a cabinet 10, a dispenser 20 for supplying drinking water in front of the cabinet 10, and a tray 30 located under the dispenser 20. The tray 30 is a storage space for receiving cups or water bottles and receiving residual water.

The dispenser 20 may include an operation unit 22 and a cock 21. When the user presses the operating portion 22, the drinking water can be supplied through the cock 21.

The dispenser 20 and the tray 30 shown in Fig. 1 are provided outside the cabinet. Therefore, the dispenser and the tray may be referred to as an external dispenser 20 and an external tray 30, respectively.

Generally, the water purifier 100 has a structure in which the external dispenser 20 is recessed into the cabinet so as to facilitate access to the cup or water bottle. That is, it has a recessed portion 40a which is recessed inward from the front of the cabinet. The outer tray 30 is positioned below the indentation 40a. Therefore, a space from the cock 21 to the outer tray 30 may be formed through the indentation 40a.

Since the residue can be minimized through the depressed portion 40a to the outside of the cabinet 100 and a space for directly operating the operation portion 22 can be secured by positioning the cup or water bottle, Do. Accordingly, the indentation 40a formed on the front surface of the cabinet 100 may be a general structure.

In FIG. 1, an operation lever is shown as an example of the operation unit 22, and an operation switch as well as an operation lever may be provided.

According to an embodiment of the present invention, a door 40 is provided on a front surface of the cabinet.

The door (40) may form an external dispenser space together with the external dispenser (20) and the external tray (30). Accordingly, at least a part of the outer dispenser 20 may be provided on at least a part of the front surface of the door 40. FIG. 1 shows an example in which a door 21 and an operating portion 22 are provided on the front surface of the door 40.

An indentation 40a is formed on the front surface of the door 40 so that an external dispenser space can be formed outside the cabinet 10 through the indentation 40a. The door 40 may be positioned above the outer tray 30. Therefore, the door (40) can be freely opened or closed while the external tray (30) is fixed to the cabinet (10).

According to the present embodiment, an inner dispenser space may be formed at the rear of the door 40. This will be described with reference to FIG.

As shown in the figure, the cabinet 10 includes an internal dispenser space 50a. The door 40 may be provided to selectively open and close the space 50a outside the cabinet 10. [

That is, when the door 40 is closed, the inner dispenser space 50a is isolated from the cabinet 10, and when the door 40 is opened, the inner dispenser space 50a is exposed to the outside of the cabinet. .

Exposure to the outside of the cabinet 10 means that a cup, a water bottle, and a user's hand can easily enter the space 50a from the outside of the cabinet, even if the cabinet is located outside the cabinet 10, It can be said that it is possible to enter and exit.

As shown in FIG. 2, it can be seen that the inner dispenser space 50a can be exposed to the outside of the cabinet 10 as the door 40 is opened. In addition, it can be seen that when the door 40 is completely opened, the internal dispenser space 50a can be exposed to a maximum area.

The inner dispenser space 50a may include an inner dispenser 50. The internal dispenser 50 may be provided to supply drinking water in the same manner as the external dispenser 20.

2, when the door 40 is opened, the door 40 may be positioned above the external tray 30. [ Therefore, the external tray 30 can no longer function as a tray. That is, when the internal dispenser 50 is used, the external tray 30 can no longer function as a tray.

Here, the tray function means receiving a residual amount, and the residual amount can be prevented from flowing out of the cabinet 10 through the tray function. Of course, the tray function could include a table function to support cups or water bottles.

When the internal dispenser 50 is used, the door 40 can function as a tray. That is, the door 40 can be referred to as being rotatable and selectively exposing the internal dispenser space 50a to the outside. When the inner dispenser 50 is used, the inner tray 60 can receive a residual water and support a cup or a water bottle.

Assuming a tray function to support a cup or a water bottle, it is preferable that the tray is substantially fixed horizontally to the paper. Therefore, from the viewpoint of the door 40, the position of the door 40 shown in Fig. 1 (door closed state) will be described below for convenience of explanation. From the viewpoint of the inner tray 60, the position of the inner tray 60 shown in FIG. 2 (the door is completely opened) will be described.

As shown in FIG. 1, if the dispenser 20 is always exposed to the outside, it is convenient because the access is very easy. However, this can easily lead to exposure to external contaminants. As shown in FIG. 2, when the dispenser 50 is selectively exposed to the outside by the door 40, the possibility of exposure to external contaminants can be reduced. This is because, when the dispenser 50 is not used, the door 40 can be closed and the dispenser 50 can be isolated from the outside. Of course, when the inner dispenser 50 is used in a large amount, the door 40 can be kept in an open state, so that there is no significant restriction in use.

Therefore, as shown in FIG. 1, the external dispenser 20 and the external tray 30 can be omitted. That is, the structure of the dispenser 20 may not be separately provided on the front surface of the door 40. In this case, the front surface of the door 40 may be provided with a decorative panel or a separate display panel.

When a function as a water purifier is required, the user can open the door 40 and receive drinking water using the dispenser 50 provided in the cabinet, that is, the internal dispenser 50.

In view of the function of the above-described dispenser, it would be undesirable to provide a water purifier having an internal dispenser 50 and an external dispenser 20 at the same time to provide the same function. In addition, the necessity of providing the same internal dispenser 50 as the structure or outflow mechanism of the external dispenser 50 to overlap can be low. Accordingly, according to the present embodiment, the water dispenser 50 and the external dispenser 20 are provided, and the water purifier can be provided between the water dispenser 50 and the water dispenser 20 so that at least one of the functions, structure, and outflow mechanism are different from each other.

For example, the external dispenser 20 may supply drinking water to the cup, and the internal dispenser 50 may supply a relatively large amount of drinking water. The external dispenser 20 may be manually supplied with water, and the internal dispenser 20 may be supplied with a predetermined amount of drinking water. That is, the internal dispenser 20 may be provided to supply a relatively large amount of water. Further, unlike the external dispenser 20, the internal dispenser 50 may be provided to supply beverages such as ice, coffee, and the like. In addition, unlike the external dispenser 20, the internal dispenser 50 can be provided to easily supply drinking water to a water bottle having various capacities, heights and shapes.

Hereinafter, an embodiment in which the external dispenser 20 is provided in the door 40 will be described in detail.

1, the cock 21 of the external dispenser 20 is provided in the door 40, and the door 40 can be opened as shown in FIG. Therefore, the purified water inside the cabinet 10 must be able to be supplied to the cock 21 through the rotatable door 40.

As shown in FIGS. 3 and 4, the external dispenser flow path 21a may be installed in the door 40 or the internal tray 60. Since the external dispenser flow path 21a is embedded in the door 60, the external dispenser flow path 21a is not exposed to the outside. The external dispenser flow path 21a can be firmly fixed to the inside of the door 40 regardless of the rotation of the door 40.

One side of the external dispenser flow path 21a may be connected to the cock 21 and the other side may be connected to the internal flow path 10a provided in the cabinet 10. Therefore, water flowing from the internal flow path 10a to the external dispenser flow path 21a can be supplied through the cock 21.

A hinge 41 may be provided between the external dispenser channel 21a and the internal channel 10a. The hinge allows the door 40 to be rotatably supported with respect to the cabinet 10 and allows the drinking water in the internal flow path 10a to be transmitted to the external dispenser flow path 21a through the inside of the hinge 41 .

Meanwhile, the flow path fixing part 42 may be provided in the door 40. The flow path fixing part 42 is preferably fixed inside the door 40 so that the other side of the external dispenser flow path 21a can be fixed inside the door 40. [ That is, the outer dispenser flow path may extend from one side of the flow path fixing part. Therefore, as the door 40 is rotated, the flow path fixing part 42 and the external dispenser flow path 21a rotate integrally with the door 40. [

The hinge 41 may be connected to the other side of the flow path fixing part 42. The flow path fixing part 42 may be connected to the hinge 41 so as to be rotatable. Therefore, when the hinge 41 is fixed, the entire door 40 can be rotated together with the flow path fixing part 42 and the external dispenser flow path 21a. Therefore, the flow path fixing part 42 may be configured to reinforce the hinge connection structure on the door 40 side.

The hinge 41 may be fixed to the cabinet 10. This fixation can be done through the fixing member 43. The fixing member 43 is interposed between the inner passage 10a and the hinge 41 so that the fixing member 43 and the fixing member 43 can be fixed to the cabinet.

The channel fixing portion 42, the hinge 41 and the fixing member 43 may be provided on both sides of the door 40, respectively. As a result, the door 40 can be firmly fixed to the cabinet 10.

Accordingly, at least two external dispenser flow paths 21a can be formed through these structures provided on both sides.

In FIG. 1, purified water, hot water and cold water can be selectively supplied through one cock 21. Therefore, purified water, hot water and cold water can be selectively supplied through one external dispenser channel 21a. This can be realized by allowing the internal flow path 10a to selectively communicate with the purified flow path, the cold water path, and the hot water path, which are not shown.

On the other hand, unlike FIG. 1, two corks may be provided. In this case, two external dispenser flow paths 21a connected to the two corks may be installed in the door 40. [ Therefore, by providing the flow path fixing portion 42, the hinge 41, and the fixing member 43 on both sides, this variety can be ensured.

The inner tray 60 extends further into the cabinet 10 with respect to the hinge 41. That is, it is preferable to extend to the inner dispenser space 50a. Therefore, in the inner tray 60, a portion extending to the cabinet inner portion with respect to the hinge 41 may be referred to as a tray extension portion 64.

The tray extension 64 forms the lower surface of the internal dispenser space 50a or rotates inside the cabinet 10 when the door 40 is closed. Therefore, it can be said that it is substantially always located inside the cabinet 10.

On the other hand, the portion extending to the outside of the cabinet with respect to the hinge 41 may be referred to as a tray main portion 63. The tray main portion 63 may be substantially the rear portion of the door 40. That is, the rear portion corresponding to the door front surface 42 exposed to the outside of the cabinet may be referred to as a tray main portion 63.

The tray main portion 63 can function as a tray for substantially supporting a water bottle and allow the remaining water to flow to the tray extension portion 64. A tray drain hole 65 may be formed in the tray extension portion 64 and the residue may be drained to the inside of the cabinet 10 through the tray drain hole 65.

The inner tray (60) includes a base (61). Which includes a portion that extends further into the cabinet 10 with the rear portion of the door 40. Therefore, the base 61 may include the tray main portion 63 and the tray extension portion 64.

A depression (62) may be formed in the base (61). The depression 62 may be formed to prevent the residue from overflowing through the tray 60 to the outside. In addition, the depressed portion 62 may be formed to be inclined downward toward the inside of the cabinet. Therefore, the remaining water falling on the depressed portion 62 can be moved to the inside of the cabinet 10 due to the downward inclination.

The residual water discharging structure through the inner tray 60 will be described later in more detail. In addition, the drainage or residual water storage structure provided inside the cabinet 10 will be described in detail later.

Hereinafter, the closing and opening mechanism of the door will be described in detail with reference to FIGS. 5 to 7. FIG.

A hook 70 may be provided on the upper side of the rear surface of the door 40, that is, in front of the inner tray 60. Specifically, the hook 70 may be mounted on the base 61 of the inner tray 60. The base 61 of the inner tray 60 may be coupled to the rear surface of the door 40 and the hook 70 may be fixed by passing the screw 71 through the back surface of the base 61 .

An insertion groove 10b into which the hook can be inserted may be formed on the upper side of the cabinet 10 in correspondence with the hook. Accordingly, when the hook 70 is inserted and fixed in the insertion groove 10b, the door 40 is fixed in a closed state. When the hook 70 is released from the insertion groove 10b, the door 40 is opened.

The insertion groove 10b may be provided with a latch 72 selectively connected to the hook. After the hook 70 is inserted into the insertion groove 10b and the latch 72 is engaged with the latch 70, the door 40 is kept closed. When the door 40 is closed in the closed state, the engagement between the insertion groove 10b and the latch 72 can be released. In this state, the hook 70 is momentarily pushed out by the elastic member 74 provided in the insertion groove 10b. Therefore, the hook 70 is released from the insertion groove 10b and the door 40 is opened.

Here, the door opening / closing detector 73 may be provided to detect the opening and closing of the door 40. The door opening / closing detector 73 may be provided in various forms.

For example, it may be sensed by the distance between the door 40 and the cabinet 20, and may be sensed according to the position of the hook 70.

6 shows an example of a door opening / closing detector 73 for detecting door opening / closing according to the position of the hook 70. As shown in FIG.

When the door is closed, the hook 70 is inserted into the insertion groove 10b and fixed. At this time, the hook 70 may be inserted and the door opening / closing detector 73 may be pushed out. Accordingly, when the door opening / closing detector 73 is retracted through the hook 70, the door can be detected as being closed. On the other hand, when the hook is moved out of the insertion groove 10b, the door opening / closing sensing portion 73 can advance due to the elastic member 74. Therefore, the door open / close detecting unit 73 can detect the opened state as the door is opened.

Of course, the change of the position of the door opening / closing detector 73 may be realized through various positional changes such as forward and backward, right and left, up and down, and rotation position.

As described above, the door 40 rotates about the hinge 41 located at the lower portion of the door 40. Accordingly, the upper portion is rotated by the lower portion of the door 40 to open and close. Therefore, the opening and closing of the door can be regarded as a pull down type.

 When the upper portion of the door 40 is pushed, the hook 70 is opened to be released from the insertion groove 10b. That is, when the door is opened in the closed state in the closed state, the door is opened.

Here, the door 40 may be rotated by substantially 90 degrees to be fully opened. As shown in FIG. 7, when the door 40 is completely opened, it is preferable that the inner tray 60 is substantially horizontal with respect to the ground.

It is preferable that the door 40 is opened early in the early stage and gradually opened in the latter period. Thus, the door 40 is opened quickly, while the door 40 is fully opened to minimize the impact. To this end, the door (40) may be provided with a damper structure.

A guide protrusion 65 is provided on both sides of the door 40, specifically on both sides of the tray extension 64. A guide slot 10c corresponding to the guide protrusion 65 is provided in the cabinet 10 As shown in FIG. Of course, the guide protrusion 65 and the guide slot 10c may be formed on only one side.

In order to perform the damping function, the width of the guide slot 10c corresponding to the guide protrusion 65 may be narrowed as the door 40 is opened. That is, friction can be generated between the guide protrusion 65 and the guide slot 10c.

That is, at the initial stage of opening of the door 40, there is no friction between the guide protrusion 65 and the guide slot 10c, and between the guide protrusion 65 and the guide slot 10c Thereby causing friction to occur. Therefore, the door 40 can be opened more stably.

On the other hand, when the door 40 is fully opened, the rear surface of the door 40 may be referred to as an inner tray 60. A water bottle or the like may be placed on the upper portion of the inner tray 60. This load exerts a force in the direction of further rotating the door (40). Therefore, the inner tray 60 must be firmly fixed to the cabinet 10. [

For this, a step 10d may be formed in the cabinet 10 and a part of the inner tray 60 may be brought into contact with the step 10d when the door 40 is fully opened. have. This allows the door 40 to be completely opened and fixed, and prevents the door 40 from rotating further even if there is a load.

Therefore, in the inner tray 60, the load can be distributed over the step 10d portion, the guide projection 65 portion, and the hinge 41 portion. Therefore, the inner tray 60 can be fixed to the cabinet 60 more stably.

7, when the door 40 is completely opened, the front surface 42 of the door 40 has a predetermined gap with the upper surface of the external tray 30. As shown in FIG. The predetermined gap may be filled when a load is applied to the inner tray 60 at a predetermined load or more. That is, when a predetermined excessive load is applied, the rear surface of the inner tray 60, that is, the front surface 43 of the door may be in contact with the upper surface of the outer tray 30. That is, the size of the gap is preferably determined in consideration of the load and the allowable bending displacement of the door 40.

When the front surface (43) of the door and the upper surface of the outer tray (30) are brought into contact with each other, a support point for supporting a large load is further increased. This can be a face support rather than a point or line support. Therefore, plastic deformation and breakage of the door due to the load can be prevented to some extent.

Hereinafter, the structure of the inner tray and the structure for discharging the residual water through the inner tray will be described in detail with reference to FIGS. 8 to 10. FIG.

8 shows the positional relationship of the inner tray 60, particularly the tray extension portion 63, with the main tray 80 provided inside the cabinet 10. As shown in FIG. The base 61 of the inner tray 60 is shown. The inner tray cover 69 shown in FIG. 9 can be coupled to the upper portion of the base 61, and the cross section after the coupling is shown in FIG.

The main tray 80 is provided to receive residual water discharged through the inner tray 60. The main tray 80 is installed in the lower part of the inner dispenser 50 and the cabinet 10.

As shown in FIG. 8, the inner tray 60 includes a base 61. A depression (62) may be formed in the base (61). Therefore, the residual water can be stored at least as long as the depth of depression of the depression 62.

In addition, a supporting portion 62a may be formed to protrude a predetermined portion from a rim portion of the depressed portion 62 to surround the depressed portion 62. Therefore, the remaining number of the reservoir portion 62a can be further increased by the height of the support portion 62a.

However, as will be described later, it is preferable that the depressed portion 62 is provided so as to drain the remaining water promptly even if a larger amount of remaining water is generated than the water retaining function. For this purpose, the depressed portion 62 may be formed so as to be inclined downward toward the inside of the cabinet 10.

The base 61 may include a tray main portion 63 outside the cabinet and a tray extension 64 inside the cabinet. Therefore, the remaining amount generated outside the cabinet can be guided to the tray extension portion 64 and discharged into the cabinet.

In order to discharge such residual water, a tray drain hole 64 may be formed in the tray extension portion 64. It is preferable that the tray drain hole 64 is formed to be long in the transverse direction in order to quickly discharge a large amount of residual water. This means that it is formed to be substantially perpendicular to the flow direction of the remaining water. Therefore, it is possible to discharge the residual water quickly.

In addition, a drain guide 66 extending in the longitudinal direction of the tray, that is, in the front-rear direction of the cabinet, may be formed on the base. The drainage guides 66 may be formed on both sides. Therefore, the flow of the residual water can be formed in a linear shape along the tray drain hole 64.

In addition, a flow path switching guide 67 may be provided at both ends of the drainage guide 66. The passage changing guide 67 may be provided to prevent the residual water from being formed on the outer periphery of the depressed portion 63. Therefore, the flow path switching guide 67 can collect the remaining water flowing out of the depression 63 into the tray drain hole 64.

When the residual water is generated through the drain guide 66 and the channel switching guide 67, it can be discharged to the tray drain hole 64 quickly. As a result, it is possible to prevent overflow in the inner tray (60).

On the other hand, the flow path switching guide 67 functions to isolate the flow path fixing portion 42 from the depression 63. That is, the flow path fixing part 42 can be positioned and fixed inside the flow path switching guide 67.

A hinge slot 68 may be formed on both sides of the flow path switching guide 67. That is, the hinge 41 described above can be fixed in a state in which the hinge slot 68 is enclosed. Therefore, the rotating part is not exposed to the outside, and the foreign material can be prevented from being stuck in the design and the rotating part.

An inner tray cover 69 is located on the base 62. More specifically, detachably attached to the base 62.

The inner tray cover 69 functions to support a container such as a water bottle, and the remaining amount of the inner tray cover 69 is supplied to the depressed portion 62. The upper surface of the inner tray cover 69 is spaced apart from the depressed portion 62 by a predetermined height.

A through hole 69c may be formed in the upper surface 69a of the inner tray cover 69 so that residual water may be discharged through the inner tray cover 69. [ Therefore, the upper surface 69a of the tray cover 69 functions to support the container, while the residual water is discharged through the through hole 69c. The through holes 69c may be formed in various shapes. For example, the tray cover 69 may be formed as a slit extending along the transverse direction of the tray cover 69. In addition, a plurality of such slit-shaped through holes 69c may be provided.

In order to form a predetermined height between the upper surface 69a and the depressed portion 62, side walls 69b extending downward may be formed on an edge of the upper surface 69a. Therefore, the inner space formed by the upper surface 69a and the side wall 69b becomes empty. Therefore, through the through hole 69c and the empty space described above, the remaining water can be discharged to the depressed portion 62.

As described above, a water bottle or the like is placed on the inner tray cover 69. The more water the water bottle gets, the more the load increases. Therefore, the upper surface 69a of the inner tray cover 69 may be pushed downward to be deformed and damaged.

Therefore, a structure may be required to support the gap between the depressed portion 62 and the upper surface 69a. At least one of the drainage guide 66 and the flow path switching guide 67 may be such a supporting structure.

The drain guide 66 is formed in the longitudinal direction, and the through hole 69c is formed in the lateral direction. Therefore, clogging of the through hole 69c due to the drain guide 66 can be minimized. In addition, it is possible to form the drain guide 66 at a position where the bucket is substantially placed in relation to the cock 21.

In addition, the inner tray cover 69 can be supported through the support portion 62a. The upper surface of the support portion 62a may be formed flat so as to have a predetermined width. Therefore, the inner tray cover 69a can be supported through the upper surface of the support portion 62a.

Meanwhile, in order to more firmly support the inner tray cover 69a, the height of the upper surface of the support portion 62a and the height of the drainage guide 66 may be the same. Therefore, the upper surface 69a of the inner tray cover 69a can be supported at various positions.

A certain amount of residue may remain in the depression 62 through the above-described drainage structures. At this time, when the door (40) is closed, the remaining amount may suddenly be turned toward the inside of the cabinet. The flow of the residual water can form an overflow to the left and right of the inner tray 60 beyond the depression 62. Of course, an overflow can be formed inside the cabinet. That is, there is a possibility that the water is drained to the upper portion of the inner tray cover 69 to flow out from the front of the cabinet 10 to the left and right. There is a possibility of overflow to the inside of the cabinet 10 and to flow out between the main tray 80 and the inner wall of the cabinet 10.

In order to prevent this, a residual water overflow prevention guide 69d may be formed on the inner tray cover 69. [

The remainder overflow prevention guide 69d may protrude from the rear upper portion of the inner tray cover 69. Specifically, it can be formed at the rear edge portion. And may be formed at a portion corresponding to the internal dispensing space 50a.

Therefore, when the door 40 is closed, it is possible to prevent the residual water from escaping to the inner tray cover 69 and overflowing to the rear and both sides.

The remainder overflow prevention guide 69d may function to temporarily increase the remaining water storage space in the inner tray 60 when the door 40 is closed. Therefore, as the residual water storage space temporarily increases, it is possible to sufficiently secure the time for draining remaining water through the tray drain hole 65.

Therefore, even when the door 40 is quickly closed, the remaining amount of the inner tray 60 can be drained only through the tray drain hole 65, so that leakage of the residue to the outside or inside of the cabinet can be minimized.

As described above, the inner tray cover 69 can be seated and coupled to the upper portion of the base 61. And, it is preferable that it is easily separable. To this end, the side wall 69b of the cover 69 may be seated on the base 61 in the form of wrapping the support portion 62a. That is, the cover 69 may be coupled to the base 61 such that the inner surface of the side wall 69b and the outer surface of the support portion 62a are in contact with each other.

Meanwhile, the cover 69 should be easy to attach and detach to the base 61 for cleaning or the like. In addition, the cover 69 must be firmly fixed to the base 61 regardless of the position of the door 40. Therefore, the coupling relationship between the cover 69 and the base 61 is very important.

Hereinafter, the coupling relationship between the tray base 61 and the inner tray cover 69 will be described in detail with reference to FIGS. 11 to 13. FIG.

Connection grooves 62b and 62c are formed in the tray base 61 and locking projections 69e and 69f may be formed in the tray cover 69. [ Therefore, the locking protrusions 69e and 69f are inserted into the coupling grooves 62b and 62c so that they can be coupled.

Specifically, it is preferable that the locking protrusions 69e and 69f are slidably fixed to the inside of the cabinet 10 by the coupling grooves 62b and 62c. That is, at the position shown in Fig. 12, the cover 69 is slid to the left and fixed as shown in Fig.

Here, sliding and fixing to the inside or the left side of the cabinet 10 is intended to maintain the fixed engagement of the door 40 in spite of the rotation of the door 40.

When the door 40 shown in Fig. 11 is closed, the position of the door 40 changes as shown in Fig. Here, when the door 40 is closed, the cover 69 tries to move downward due to its own weight. Here, moving downward is a direction in which the cover 69 is fixed to the base 61.

Therefore, due to the engagement structure of the engagement protrusions 69e and 69f and the connection recesses 69b and 69c, the engagement of both can be firmly maintained regardless of the position of the door 40. [

More specifically, the latching protrusions 69e and 69f may be formed on both sides of the side wall 69b of the cover 69. In addition, two locking projections may be formed in the front side wall on one side wall.

The connecting grooves 62b and 62c may include an outer groove 62b and an inner groove 62c and the engaging protrusions 69e and 69f may include vertical protrusions 69e and transverse protrusions 69f . The transverse protrusion may be formed to extend forward from a lower end of the vertical protrusion. In addition, the inner groove may be formed to extend forward from the lower groove bottom. The width of the outer groove may be formed such that the latching protrusion can be inserted with sufficient space.

Therefore, as shown in FIG. 12, the latching protrusion can be inserted with sufficient space from the upper part to the lower part. Thereafter, the latching protrusion can be moved forward. At this time, the transverse protrusion 69f may be inserted into the inner groove 69c as shown in FIG. Due to such a coupling structure, the cover 69 can be fixed to the support portion 62a. Of course, it can be easily mounted and detached.

On the other hand, the tray 69 or the door 40 shown in Fig. 12 is in the position shown in Fig. 13 in the closed state. The direction of load of the cover 69 becomes the same as the direction of engagement of the cover 69. Therefore, it can be firmly fixed regardless of whether the door 40 is open or closed.

Hereinafter, the tray structure, the tray mounting and demounting structure, and the drainage structure through the tray will be described in detail with reference to FIGS. 14 to 18. FIG.

The main tray 80 is provided for receiving residual water discharged through the inner tray 60. Therefore, it is preferable to provide the lower part of the inner dispenser 50 and the inside of the cabinet.

More specifically, it is positioned above the tray drain hole 68 of the inner tray 60 as shown in Fig. Accordingly, the remainder drained through the tray drain hole 68 can be stored in the main tray 80 or can be drained out of the cabinet through the main tray 80.

The main tray 80 needs to be installed in the cabinet 10 for easy cleaning or water discharge. In addition, the main tray 80 can store a large amount of remnants. Therefore, when the main tray 80 is detached from the cabinet, the remaining amount of the main tray 80 may leak out to the outside. Of course, separation of the main tray 80 may not be easy due to the weight due to the residual water.

In order to solve such a problem, according to the embodiment of the present invention, it is preferable that the main tray 80 is mounted and separated in a drawer form in front of the cabinet. That is, it desirably desorbs in the form of a drawer.

An external tray 30 exposed to the outside of the cabinet may be provided in front of the main tray 80 to draw the main tray out of the cabinet. Here, the outer tray 30 may be referred to as a main tray handle for pulling out the main tray 80. In this regard, the outer tray 30 may be referred to as a sub tray 30, and the outer tray and the sub tray hereinafter refer to the same configuration.

The sub tray 30 may be exposed to the outside of the cabinet, and may be positioned below the external dispenser 20. Therefore, the residual water generated by the external dispenser 20 can be received in the sub tray 30.

The sub tray 30 may form part of the front and side surfaces of the water purifier. That is, it can be exposed to the front of the cabinet.

More specifically, the sub tray 30 may include a housing 31, a sub tray container 33, and a sub tray cover 34.

The housing 31 forms a part of a front surface and a side surface of the water purifier, and an opening 32 may be formed in an upper part of the water purifier. The sub tray container 33 can be inserted and mounted through the opening 32 of the housing. Of course, the sub tray vessel 33 mounted through the opening 32 can be easily separated. The sub tray cover 34 is mounted on the opening.

14 shows that the sub tray container 33 is mounted on the housing 31 and the sub tray cover 34 is mounted on the opening portion 32. [

Preferably, the housing is clogged with a front surface and both side surfaces, and the rear surface is opened. This is because even if the residual water leaks through the open rear surface, such residual water may fall into the main tray 80 as shown in Fig. That is, even if the residual water leaks through the gap between the cabinet and the sub tray 30, such residual water can be received in the main tray 80.

It is preferable that the sub tray 30 is integrally connected to the main tray at a lower portion of the housing 31. That is, as one assembly, the sub tray 30 and the main tray are integrally mounted in the cabinet and can be detached from the cabinet again.

In addition, the lower surface of the sub tray container 33 may be positioned higher than the main tray 80. This is because when the sub tray vessel 33 is mounted, the sub tray vessel 33 can press the surface of the residual water when the main tray 80 is full. In this case, residual water may leak from the main tray 80.

On the other hand, the lower surface of the sub tray vessel 33 may be closed or open. The opening is preferable in an environment in which automatic drainage is possible as described later, and the case in which it is blocked is preferable in an environment in which automatic drainage is not possible as described later. Accordingly, both of the sub tray vessels 33 may be provided and selectively used depending on the installation environment.

The sub tray may communicate with the inner tray. That is, they can communicate with each other through the lower portion of the sub tray vessel 33. Therefore, the remainder discharged to the sub tray can be discharged to the inner tray through the sub tray.

The main tray 80 may include a main tray 81. The main tray container 81 may be formed integrally with the housing 30. Accordingly, the main tray container 81 can extend to the inside of the housing 30. [ Through this, the capacity that can be stored can be further increased.

A drain hole may be formed in the rear of the main tray 80. Specifically, the drain hole 82 may be formed to protrude rearward. As shown in FIG. 14, the drain hole 82 may be formed to protrude from the rear lower portion of the main tray container 81.

The main tray 80 may be inserted into the tray space 11 formed in the cabinet 10 as shown in FIG. That is, it can be drawn out into the tray space 11 in the form of a drawer.

An insertion portion 14 can be formed in the tray space 11 so that the drain hole 82 can be inserted and fixed. The main tray 80 can be fixed in the correct position to the tray space 11 by the combination of the drain hole 82 and the insertion portion 14.

On the other hand, the drain hole 82 may be blocked or opened depending on the environment in which the water purifier is installed. Although not shown, a drainage passage is formed in the insertion portion 14 to drain the residual water from the inside of the cabinet 10 to the outside of the cabinet. That is, in the environment where the drainage facility is provided, the drainage hole 82 may be opened, and in the opposite case, the drainage hole 82 may be closed. The former can be called automatic drainage, and the latter can be called manual drainage. Of course, even in the case of automatic drainage, the tray needs to be easily separated from the cabinet for tray cleaning.

In order to facilitate mounting and dismounting of the main tray 80, a rail structure may be provided. Of course, as described above, since the main tray 80 and the sub tray 30 are formed as one assembly, that is, a tray assembly, the mounting and separation of the tray is facilitated.

Rails 83 may be provided on both sides of the main tray 80. In addition, a rail slot corresponding to the rail 83 may be provided in the cabinet. That is, the rail slot 12 may be provided on both side walls of the tray space 11.

The rail 83 may be formed to be long along the longitudinal direction to be inserted, and may protrude to both sides. Correspondingly, the rail slot may be formed in a groove shape. Of course, the position of the rail slot and the rail may be reversed. That is, a rail slot may be formed in the main tray 80, and a rail 83 may be formed in the cabinet 10.

A roller 84 may be provided at a rear portion of the rail 83, that is, at a position further inside the cabinet. This roller 84 can be inserted into the rail slot 12 in an initial state in which the tray is mounted. Of course, even when detached, the impact generated between the cabinet and the main tray can be minimized.

Therefore, the roller 84 can be said to extend further to the rear of the main tray 80. Corresponding to the shape of the roller 84, the trailing end shape of the rail slot 12 can be formed. In other words, the curved portion 12a may be formed at the rear end of the rail slot 12 so that the two are combined. The main tray 80 can be inserted and fixed to the correct position through the curved portion 12a.

The upper surface of the container 81 of the main tray 80 may be inclined downward from the front to the rear. This means that the rear surface area of the main tray container 81 is smaller than the area of the tray space 12, that is, the area into which the tray is inserted. Therefore, the tray 80 can be smoothly inserted, such as by inserting a small projection into a large hole.

When the main tray 80 is left with a large amount of residual water, the residual water may leak when the main tray 80 is separated from the cabinet. For example, when the main tray 80 is suddenly detached, there is a lot of possibility that the residual water is generated in the residual water. Therefore, it is necessary for the user to smoothly and stably separate the main tray in consideration of this.

For this purpose, a stopper groove 85 may be formed at an intermediate portion of the rail 83, and a stopper 13 may be formed at the front of the rail rail slot 12. That is, when the main tray 80 is separated from the cabinet 10 to some extent, the stopper 13 is caught in the stopper groove 85. Therefore, a reaction force is generated in a direction in which the main tray 80 is not separated. In this case, the user feels that a force is applied to the main tray 80, and the main tray 80 can be smoothly removed while lifting up the main tray 80.

In other words, when the stopper 13 and the stopper 85 are engaged with each other, the user can see the inside of the main tray 80. Therefore, it is possible to confirm how much of the residual water is stored and whether or not the residual water is fluctuated. Therefore, the main tray 80 can be completely separated from the cabinet with care while checking the wobbling of the residual water. This makes it possible to prevent overflow in the main tray (80).

Hereinafter, the internal dispenser will be described in detail with reference to FIGS. 19 to 22. FIG.

As described above, when the door 40 is opened, the inner dispenser space 50a provided in the cabinet is exposed to the outside of the cabinet. The inner dispenser space 50a is provided with a dispenser for supplying drinking water, beverage, or ice. In addition, the rear surface of the door 40 functions as a tray when the dispenser 50 is used. Accordingly, when the door 40 is opened, the inner dispenser 50 and the inner dispenser tray 60 are exposed together.

The size of the door 40 is proportional to the size of the inner dispenser tray 60. Accordingly, the inner dispenser tray 60 can have a larger area than the outer tray 30 described above. This is because, when not in use, the inner dispenser tray 60 can be closed again to minimize the portion protruding forward of the cabinet 10.

Therefore, water can easily be filled in the inner dispenser tray 60 in a state in which large water bottles are supported. Therefore, the internal dispenser 50 provides a very suitable structure for receiving a large amount of water in the water bottle.

The dispenser 50 includes a cork 100, 200, and 300. Specifically, a plurality of the cork portions may be provided. 19 to 22 show that there are three cork portions. Here, the plurality of cork portions may have the same structure. Therefore, since the detailed configurations of the cock portions may all be the same, only one of the cock portions can be described in detail.

The cock portion 100 includes a cock 140. Drinking water or beverage is supplied through the cock 140. When three corks are provided, each of the corks may be referred to as a first coke, a second coke, and a third coke.

Here, the position of the cock 140 is preferably varied to smoothly supply drinking water to water bottles of various sizes. That is, it is preferable to make it possible to move up and down. The gap between the cock 140 and the inner tray 60 can be adjusted by the vertical movement of the cock. This means that water can be supplied smoothly even to low-height water bottles or high-height water bottles.

Specifically, the vertical position of the cock 140 may vary as the cock 140 rotates from the center. The rotation center of the cock 140 may be referred to as a coke header 110. A coke body 120 is provided between the coke header 110 and the coke 140. Accordingly, the pipe shape extending from the coke header 110 may be referred to as a coke body 120, and the coke 140 may be provided at a distal end portion of the coke body 120.

The coke header 110 is rotatably provided. In addition, the cork body 120 is branched in the coke header 110. Therefore, the cork body 120 can be rotated integrally with the cork header 110 by the rotation of the cork header 110. The rotation of the coke header 110 can be varied by the rotation of the coke body 120.

A handle 130 may be provided to easily vary the position of the cock 140. That is, the cork header 110 can be rotated by holding the handle 130. Specifically, the handle 130 may be provided on the cock body 120. As a result, the vertical position of the cock 140 can be changed while holding the handle 130 to lift or lower the cock body 120. Of course, in spite of this position change, it is desirable that the coke header 110 be rotatable, but not translationally movable.

The handle 130 is formed along the longitudinal direction of the cock body 120 and may be formed in an arc shape into which a user's finger can be inserted. That is, an arc-shaped opening corresponding to the handle shape is formed between the handle 130 and the cork body 120.

Specifically, the handle 130 may be formed to protrude in an arc shape in parallel with the longitudinal direction of the cock body 120. In addition, the handle may be formed of a rubber material. Therefore, the grip feeling can be improved. In addition, the handle may extend to the cork header 110 with one end wrapping around the cork body. That is, the cork body 120 may be extended to the cork header 110 in a coated state.

In addition, the handle 130 may be provided with an outflow button 135. That is, the outflow button 135 may be provided on the handle 130 exposed on the front surface 130 of the user.

Preferably, the front surface of the outflow button 135 is waterproofed with a membrane sheet. Therefore, even if the user presses the water-supply button 135 with a wet hand, it is possible to prevent water from penetrating into the water-supply button 135.

Fig. 21 shows a user holding the handle. Therefore, the position of the cock can be easily changed through the handle 130. [ In addition, as shown in the figure, the user can adjust the position of the coke through the handle and press the water-release button 135 to perform water-out. That is, it is very convenient to use only one hand to control the cock and to operate the push button at the same time.

As shown in FIG. 19, the plurality of cork portions 100, 200, and 300 may be separately rotatable. That is, only one of the cork portions can be rotated at the home position (the position where the cork body 120 is placed vertically). It is possible to rotate all the cork parts in the same manner as shown in Fig. 20, and to change the rotation angles as shown in Figs. 21 and 22, respectively.

FIG. 22 shows a state in which water can be conveniently supplied to two water bottles having different heights at different positions of the cock portions. As shown in the figure, the position of the cock 140 may protrude forward from the dispenser space 50a. Nevertheless, the position of the cock 140 is always located on the inner dispenser 60. In addition, the dispenser space 50a is opened frontward. Therefore, the front and back position of the cock 140 can be changed smoothly due to the vertical position change of the cock 140. After the use, the corks can be returned to the above-described original position, and when the door 40 is closed, the portion protruding forward of the cabinet 10 can be minimized.

Each of the cork parts 100, 200 and 300 may be formed of one module. That is, the cork header 110, the cork body 120, and the cork 140 may be formed of one module. Such a module makes it easy to expand the number of cork parts. That is, two corks, three corks, and further corks can be easily configured. Of course, in the embodiment of the present invention, three cork portions are provided, but the present invention is not limited thereto. The cock section or the cork module 100 will be described in detail later.

Hereinafter, a user interface (UI) will be described in detail with reference to FIG.

FIG. 23 shows a UI corresponding to the internal dispenser 50. FIG. This UI 54 may be located on the top of the inner dispenser 50 as shown in FIG. In addition, the inner dispenser 50 and the inner dispenser tray 60 may be selectively exposed to the inside of the cabinet. That is, when the internal dispenser 50 is used, the internal UI 54 may be exposed outside the cabinet.

As described above, the internal dispenser 50 is very effective in supplying a large amount of water to a container such as a water bottle. In addition, water can be simultaneously supplied to a plurality of water bottles through the plurality of corks 100, 200, and 300. In addition, not only purified water but also hot water or cold water can be supplied. Therefore, it is preferable that different drinking water can be simultaneously supplied to a plurality of water bottles having various sizes.

To this end, an internal dispenser UI 53 is provided which can be intuitively and conveniently used by the user. Of course, the internal dispenser UI may be a UI for using the internal dispenser 50.

In addition, the UI may be provided separately for each cock section. That is, the first UI for the first cock portion 100, the second UI for the second cock portion 200, and the third UI for the third cock portion 300, respectively. Of course, it is preferable that the position of the UI is located on the upper part of the corresponding cock section.

Here, it is preferable that the amount of the drinking water to be supplied to the internal dispenser 50 can be preset. Therefore, it is preferable that the capacity selection units 55b, 56b, 57b are provided in each UI. Thus, the amount of drinking water to be supplied can be preset. The capacity selected through the capacity selection unit may be displayed on the capacity display units 55c, 56c, and 57c. In Fig. 23, for example, 2.0, 1.5, 1.0, and 0.5 liters are shown as selectable capacities.

If the capacity selected in accordance with the depression of the capacity display portion 55c is sequentially changed, it can be clearly displayed to the user by the lighting brightness.

On the other hand, in the case of a commercial water purifier, it is necessary to receive water from many water bottles at a time. Thus, the three cocks can be provided to supply essentially pure water. However, receiving large quantities of hot water can be dangerous. This is because, if a large amount of hot water is automatically supplied, hot water may overflow due to the user's carelessness. For example, a 2 liter water bottle contains 1 liter of water, allowing the user to inadvertently supply 2 liters of hot water. In this case, hot water may overflow while the user is away. Therefore, when a large amount of drinking water is supplied, hot water may not be provided.

However, in the case of a commercial water purifier, an appropriate amount of cold water may be urgently needed. Therefore, it is necessary that one of the cock portions is provided so that cold water and purified water can be selectively supplied. Accordingly, as shown in FIG. 23, constant and cold water can be selected through the UI 56 corresponding to the cock part 200 positioned at the center. The user can select whether the water is purified water or cold water by pressing the water button 56a and the cold water button 56d.

In the case of a water purifier, constants can be continuously supplied. However, in the case of cold water, it is difficult to continuously supply cold water having a predetermined temperature. This is because the basic function of the water purifier is an integer, not a chiller. Therefore, it is desirable to indicate to the user how much current cold water capacity that can be continuously supplied. To this end, the UI 56 preferably includes a cold water capacity display portion 56e.

On the other hand, it is possible to supply drinks such as ice and coffee through an internal dispenser. For example, an apparatus for producing coffee using an integer may be provided in the cabinet 10. The basic drinking water supply function can use an external dispenser, and special functions such as ice or drink supply may be implemented in the internal dispenser.

As described above, the internal dispenser 50 can supply a predetermined amount of drinking water. This can be called the quantitative mode. In addition, an additional mode of supplying ice or beverage may be provided. This is because it is not a basic function of a water purifier, but an ice or beverage supply function is added. When the mode in which water is manually supplied and operated is referred to as a basic mode, the quantitative mode or the additional mode may be a special mode.

The user can determine the amount of water to be supplied through the UI 54 and predetermined water can be supplied irrespective of the pressing time by pressing the water out button 135 provided in the cock portion 100. [ That is, once the pressure is generated, a predetermined amount of water can be supplied. Therefore, there is no need for the user to wait for the water to be supplied while holding the water bottle. That is, other things can be done while water is being supplied. In addition, water can be supplied simultaneously to a plurality of water bottles. It is therefore very convenient.

Hereinafter, the structure of the cork or cork module, the connection relationship between the cork modules, and the supporting structure of the cork module will be described in detail with reference to Figs. 24 to 30.

As shown in Fig. 24, the cork portion 100 can be rotatably supported through the frame 400. Fig. The frame 400 may be fixed to an upper portion of the inner dispenser space 50a. In addition, a plurality of corks can be supported through one frame 400. That is, a plurality of cork portions may be connected to each other through the frame 400, and the connecting portions may be independently rotated.

In addition, the frame 40 may be a medium that allows a flow path extending from the inside of the cabinet 10 to be connected to the cock portion 100. That is, the passage 10f inside the cabinet 10 can be connected to the cock portion 100 through the frame 40. [

As shown, the same plurality of corks can be rotatably connected to each other through a single frame 400. Due to the structure of each of these cork portions, the number of cork portions can be further increased as necessary.

Hereinafter, the structure of the cock or cork module 100 will be described in detail.

As described above, the cork portion 100 may include a cork header 110, a cork body 120, and a cork 140.

The coke header 110 is rotatably supported by the frame 400 and is adapted to supply drinking water through the coke body 120. That is, it may be a medium for providing drinking water supplied from the inside of the cabinet 10 to the cock body 120. In addition, the cork body 120 may be supported in the inner dispenser space 50a through the coke header 110.

In addition, although not shown, the coke header 110 may be a medium through which electric wiring is connected. This is because the cock button 120, particularly the handle 130, can be provided with the outflow button 135. An electrical signal generated by the operation of the outgoing button 135 must be transmitted to the control unit provided inside the cabinet through the cock header 110. [

In order to perform these various functions, the coke header 110 may include the following configurations.

First, the cork header 110 may include a cork header body 111. The coke header body 111 forms an internal space. Therefore, the connection of the flow path, electric wiring, or the like can be made through the internal space.

A first cork header cover 112 and a second cork header cover 114 may be provided on both sides of the cork header body 111, respectively. The covers 112 and 113 may be coupled to the body 111. Here, the covers 112 and 113 can support the cork module 100 in a rotatable manner. That is, the covers 112 and 113 may be formed at the center of rotation of the body 111. For this purpose, each of the covers may be formed with rotating shaft holes 112a and 114a at the center thereof. The rotary shaft 115 may be inserted into the rotary shaft holes 112a and 114a. Of course, the rotating shaft 115 itself may be provided instead of the rotating shaft holes 112a and 114a.

The first cork header cover 112 and the second cork header cover 114 can be integrally rotated about the rotation shaft 115 provided at both sides of the cork header body 111, have.

Here, since the cork header body 111 is configured to rotate, it is preferable that the cork header body 111 is formed in a cylindrical shape so that the rotation can be smoothly performed. In addition, a body hole 111c may be formed on a circumferential surface of the cork header body 111 to connect the cork body 120 to the body surface. The cork body 120 may be connected to the body 111 through the body hole 111c. Specifically, the body hole 111c is formed at the center of the body 111 in the longitudinal direction of the body 111, so that the body 111 can be balanced right and left.

25, it is preferable that an opening 111d is formed in the circumferential surface of the body 111 so that the external passage 10f extends into the body 111. As shown in FIG. It is preferable that the external flow path 10f can not be seen by the user from the front of the cabinet within the permissible rotation range of the body 111. [ Therefore, it is preferable that the position of the opening 111d is formed on the opposite side of the body hole 111c. Here, the external flow path 10f may be a flow path extending into the coke header body 111 to supply drinking water from the inside of the cabinet to the coke 140. Of course, it is preferable that not only the flow path but also the electric wiring extend into the body 111 through the opening 111d.

As shown in the figure, the opening 111d may be formed by cutting the circumferential surface of the body 111. That is, the circumferential surface does not have 360 degrees, for example, only the circumferential surface of 250 degrees and the circumferential surface corresponding to 110 degrees may have an incised shape.

Here, the angle at which the circumferential surface is cut, for example, 110 degrees, is related to the rotation angle of the cork header body 111, that is, the allowable rotation angle. This is because, as described above, it is not preferable that the opening 111d is exposed to the outside. However, in order to smoothly rotate the cock header body 111, it is preferable that the circumferential surface is formed according to 360 angles. For example, it is preferable that the circumferential surface corresponding to the incised 110 degrees is formed at least at a certain portion along the longitudinal direction of the cork header body 111. [

Accordingly, as shown in FIG. 24, the cork header body 111 may include a first cork header body 111a and a second cork header body 111b. The opening 111d may be formed in the first cork header body 111a and the second cork header body 111b may be formed to completely cover a portion of the opening in the longitudinal direction of the opening 111d.

According to the structure of the coke header body 111, the opening 111d is held on both sides along the longitudinal direction of the coke header body 111 and the opening 111d of the center portion is held by the second coke header body 111b ). The second cork header body 111b refers to an area that is rotated with respect to the frame 400. Therefore, the cork header body 111 can be smoothly rotated with respect to the frame 400. [

The first cork header cover 112 and the second cork header cover 114 may be formed to cover the open portions of the first cork header cover 112 and the second cork header cover 114, respectively. That is, they may be provided so as to block the openings on both sides.

The coke header 110 needs to be limited in the allowable rotation angle. It is also preferable that it can be fixed in a rotated state. For example, when the user rotates the cork header 110 by 90 degrees, the cork header 110 needs to be fixed. That is, it is necessary to prevent return to the home position due to its own weight.

Therefore, it is necessary that the coke header 110 is rotated in multiple steps, and the rotation is fixed in each step. For this purpose, it is necessary to provide a stopper device for multi-step rotation and fixing of the coke header 110. [

25 and 26, the stopper device may include a plurality of protrusions 112b formed along the circumference of the coke header 110 and a stopper 113a formed to be engaged with the protrusions . When the cork header 110 is rotated and the protrusion 112b and the stopper 113a are engaged with each other, the resistance of the cork header 110 increases in both directions against rotation of the cork header 110. [ This resistance force is preferably greater than the restoring force of the coke header 110 to its original position due to its own weight. On the other hand, if a predetermined force is applied, it is possible to further rotate the coke header 110 over the resistive force.

Therefore, the rotation step can be determined according to the number of the protrusions 112b. In other words, it is possible to maintain a fixed state unless a force is applied at a specific rotational position. In addition, it is possible to facilitate further rotation from any one of the rotation stages to the next rotation stage. For this purpose, the stopper 113a may be provided to retract radially outward. Therefore, the stopper supporting portion 113 supporting the stopper 113a may be provided with an elastic member 113b.

A position where the protrusion 112b and the stopper 113a are engaged is a state in which the stopper 113a is retracted radially outward. In this state, when the coke header 110 rotates, the stopper 113a advances radially inward by an elastic force. When the rotation continues and the next stopper 113a is encountered, the stopper 113a can instantaneously retreat and advance. At this time, the protrusion 112b is located at the center portion of the stopper 113a so that both protrusions can be engaged. Therefore, in each rotation step, the coke header 110 can be fixed in a stopped state.

Meanwhile, the protrusion 112b may be provided to the first cock header body 112 in detail. And is also located in the opening 111d. Therefore, direct contact between the stopper 113a and the cork header body 111 may not be achieved. In addition, due to the thickness of the first cork header body, that is, the thickness of the opening 111d, the position of the protrusion 111b, and the position of the stopper 113a, The rotation limit range can be easily set. In other words, it is possible to easily prevent the rotation exceeding the above range.

26 and 27, the stopper 113a may protrude from the inner surface of the frame 400, and the stopper supporting portion 113 may be fixed to the outer surface of the frame 400 have.

Such a stopper device can give the following effects. Can be rotated in multiple stages, and can be fixed in a rotated state. Therefore, it is not necessary to rotate the cork header 110 every time it is used, which is convenient to use. In addition, rotation can be continuously performed between one rotation step and the next rotation step. That is, it becomes possible to use a continuous rotation position within the allowable range of rotation angles, which is not fixed but can be optionally used.

Hereinafter, the connection and support relationship between the cork module 100 and the cork module 200 will be described in detail with reference to Figs. 27 and 28. Fig.

A frame supporting part 420 protruding forward is provided on the inner surface of the frame 400. A rotation shaft hole 421 may be formed in the center of the frame support part 420. Of course, such a rotary shaft hole 421 can be replaced with a rotary shaft.

The cork module can be rotatably supported on both sides of the frame supporting part 420.

Specifically, the second cork body cover 114 and the first cork body cover 112 may be rotatably connected to one side of the frame supporting part 420 and the other side of the cork body cover 112, respectively. Of course, each rotary shaft hole may be provided with a rotary shaft 115.

Here, the frame supporting part 420 is fixed to the frame 400, and the frame 400 is also fixed to the cabinet. 28, the first cork body cover 112 and the second cork body cover 113 can be rotated individually or independently on both sides of the frame support portion 420. [ Thus, each of the cork modules on either of the frame supports 420 can rotate individually or independently. In addition, since the stopper devices are individually provided in each of the cork modules, fixation by rotation can also be achieved individually.

Meanwhile, as shown in FIG. 27, a connector 410 may be formed in the frame 400. Specifically, it may be provided in the form of a through hole. The connector 410 may be formed to match the number of the cork modules 100, 200, and 300 fixed through the frame 400.

As shown in FIGS. 29 and 30, the oil passage 10f may extend into the inside of the coke header body 111 through the connecting hole 410. As shown in FIG. Of course, the connector 410 may communicate with the opening 111d of the coke header body 111. [ The flow path 10f provided in the cabinet 10 flows into the inside of the coke header body 111 through the connection port 410 of the frame 400 and the opening 111d of the coke header body 111 .

Connections 121 and 122 may be provided between the oil passage 10f and the cock body 120. [ The connection portion may include a first connection portion 121 connected to the cork body 120 and a second connection portion 122 connected to the flow path 10f. The connection portion may be provided inside the coke header body 111.

The second connection part 122 may be positioned coaxially with the rotation shaft 115. Therefore, the cork body 120 and the first connection part 121 can be rotated through the second connection part 122. [ Of course, at this time, it is preferable that the flow path 10f is fixed. In this case, the coke header 110 may also rotate together. As described above, since the opening 111d is formed corresponding to the allowable rotation angle range, interference with the flow path 10f can be prevented despite the rotation of the opening 111d.

Meanwhile, a fixing part 123 may be provided between the first connection part 121 and the cock body 120. The fixing part 123 is provided on the inside and the outside of the body hole 111c. The fixing part 123 includes a central part 123a corresponding to the diameter of the body hole 111c and an extended part 123b extending on both sides. The coupling between the cork body 120 and the cork header 110 can be firmly maintained even if a force is applied to the cork body 120 in the longitudinal direction through the fixing part 123. [

Hereinafter, the external dispenser 20 will be described in detail with reference to FIGS. 31 and 32. FIG. Of course, according to the embodiment, the external dispenser 20 may be deformed and may be omitted.

In the state shown in FIG. 31, the user can rotate the operation unit 22 counterclockwise to discharge water through the cock 21. At this time, the user can press the operating portion 22 in a state in which a cup, a bottle, or the like is in contact with the side surface of the operating portion 22. [ Of course, the operating portion 22 can be pressed while the opening of the cup or bottle is aligned with the cock 21. At this time, it is preferable that the drinking water is discharged from the cock 21 while the pressurization is maintained. That is, it is desirable to provide a passive mode.

On the other hand, as shown in FIG. 32, the user can rotate the operation unit 22 counterclockwise in the state shown in FIG. 31 to discharge water through the cock 21.

32, when the operating portion 22 is rotated, the operating portion 22 is not positioned below the cock 21, so that a space for placing a cup, a bottle, or the like in the lower portion of the cock 21, Can be increased. In particular, the bottle can be placed and placed on the tray easily.

Here, the operating portion 22 can be fixed so that the pressing operation is continuously performed at the position of the operating portion 22 shown in Fig. Therefore, unless the position of the operating portion 22 is changed from the position shown in Fig. 32 to the position shown in Fig. 31, water can be continuously supplied. Likewise, this can also be called manual mode.

That is, when the user places the operation portion 22 in the position shown in Fig. 32, the pressurization is continuously maintained so that water can be continuously supplied. Thereafter, when the water bottle is full of water, the user can change the position of the operation unit 22 to the position shown in Fig. 31 and stop the water supply.

31 and 32 show a single coke 21 which can provide various drinking water through one cock 21. Cold water or purified water may be supplied through the single cock 21. Of course, hot water can also be provided. And a dial 23 for selecting the kind of drinking water may be provided. Thus, the user can turn the dial 23 to select either purified water, hot water or cold water.

Hereinafter, the user interface for the external dispenser 20 will be described in detail with reference to FIGS. 33 to 35. FIG.

33 to 35 are diagrams showing changes of the user interface, i.e., the external dispenser UI 25, in accordance with the rotation of the dial 23 in this embodiment.

FIG. 33 shows a state in which purified water, which is filtered at normal temperature, can be supplied through the cock 21, FIG. 34 shows a state in which cold water can be supplied through the cock 21, And the hot water can be supplied through the cock 21.

As shown in the figure, depending on the kind of water supplied through the cock 21, windows corresponding to the integer, cold water and hot water of the UI 25 are activated, that is, turned on, have. For example, in a state where purified water can be supplied through the cock 21 by the rotation of the dial 23 as shown in FIG. 33, it is preferable that the window relating to hot water and cold water is inactivated.

Therefore, the user can intuitively know what kind of water can be supplied from the single cock 21 through the lighting of the UI 25, which is very convenient to use.

The single cock 21, the dial 23 and the user interface 90 can provide a water purifier which is very simple and beautiful in appearance and is easy to use.

On the other hand, windows relating to cold water and hot water can be arranged on both sides with respect to an integer. Since the water is at room temperature, it has an intermediate image of cold water and hot water. Therefore, for convenience of the user, it is possible to arrange the windows sequentially as cold water, purified water, and hot water.

For example, if the user desires to receive cold water in the state of FIG. 33, the dial 23 may be rotated clockwise.

On the other hand, when the user wishes to receive hot water through the cock 21, the dial 23 may be rotated counterclockwise.

The user can select a menu related to on / cold water off, cold water off, and hot water off by pressing the power save button shown on the left side of FIG. Depending on the number of times the user presses the power saving button, the menu related to on / cold water off, cold water off, and hot water off may be sequentially changed, and all three menus may not be selected.

For example, when the user selects on / cold water off, the operation of the cooling apparatus such as the heater for heating the hot water tank provided in the case 10 and the compressor for cooling the cold water tank may be stopped . In this case, both the display window showing the remaining capacity of the hot water and the display window showing the remaining capacity of the cold water can be turned off.

If on / cold water off is selected, cold water and hot water may not be provided through the cock 21 even if the user rotates the dial 23. Since the manufacture of hot water and cold water is discontinued, only hot water and cold water stored in the hot water tank and the cold water tank can be supplied, and hot water and cold water can not be additionally supplied. On the other hand, even if the hot water and the cold water are stored in the hot water tank and the cold water tank, it is possible to supply only the water to the user.

When the user selects cold water off, the operation of the cooling device for cooling the cold water tank provided in the case 10 can be stopped. Also in this case, the display window showing the remaining capacity of the cold water may be turned off.

When cold water off is selected, cold water may not be supplied through the cock 21 even if the user rotates the dial 23. Since the production of cold water is stopped, only the cold water previously stored in the cold water tank can be supplied, and no additional cold water can be supplied. On the other hand, even if the cold water is stored in the cold water tank, it is possible for the user to supply the non-cold water.

When the user selects the hot water off, the operation of the heating device for heating the hot water tank provided in the case 10 can be stopped. In this case, the display window showing the remaining capacity of the hot water may be turned off.

When the hot water off is selected, hot water may not be supplied through the cock 21 even if the user rotates the dial 23. Since the production of hot water is stopped, only the hot water stored in the hot water tank can be supplied, and no additional hot water can be supplied. On the other hand, even if the hot water is stored in the hot water tank, it is possible to supply the user with non-hot water.

Hereinafter, the configuration of the water purifier according to the embodiment of the present invention will be described in detail with reference to FIG.

The water purifier according to the embodiment of the present invention may include the purified water unit 2. Constants can be generated from the raw water through the integer unit (2). In addition, a hot water unit 3 for generating hot water from the purified water may be provided. Of course, a cold water unit 4 for generating cold water from the purified water may be provided.

The hot water unit 3 may include a hot water tank or a heater, and the cold water unit 4 may include a cold water tank, a chiller, or the like.

In addition, the water purifier may include various valves 5. The various valves 5 may be provided on various flow paths, and the type of the drinking water to be supplied may be changed depending on whether the valves 5 are opened or closed. In addition, depending on whether the various valves 5 are opened or closed, cold water generation or hot water generation can be performed. Here, the various valves 5 include a flow meter and a solenoid valve.

Therefore, basically, the control unit 1 must be provided to control the operation of these various valves 5. [ The control unit 1 controls the operation of the water purifier unit 2, the hot water unit 3 and the cold water unit 4 together with the operation of the valves 5.

The water purifier can be made up including the UI. Through this UI, the user can select the kind of drinking water or the supply amount. Accordingly, the control unit 1 controls the operation of the above-described various configurations in response to the input through the UI.

Here, the UI may be provided as a main UI 25 and a sub UI 54. That is, a separate UI may be provided for each of the dispensers provided separately from each other. For example, when the external dispenser and the internal dispenser are provided, the main UI 25 may be an external dispenser UI. And may be referred to as an internal dispenser UI of the sub UI (54).

In the above-described embodiment, the inner dispenser 50 is selectively exposed to the outside by opening and closing the door 40. That is, when the internal dispenser 50 is used, it is preferable that the use of the external dispenser 20 is excluded. And vice versa. Accordingly, it is preferable that the use of the external dispenser UI is excluded when the internal dispenser UI is used. Of course, the opposite is true.

The controller 1 may control the main UI 25 and the sub UI 54 depending on whether the door is opened or closed through the door opening / closing detector 74.

For example, if the door 40 is detected to be in a closed state, the control unit 1 may turn off the power of the sub UI 54 or disable the sub UI 54. Similarly, when the door 40 is detected as being open, the control unit 1 may turn off the main UI 25 or disable the main UI 25.

The control unit 1 controls the operation of the water purifier unit 2, the hot water unit 3, the cold water unit 4 and the various valves 5 depending on whether the doors detected through the door opening / closing detection unit 74 are opened or closed. Control can be different.

For example, it may be set to a state in which cold water can be supplied through the main UI 25 and a state in which cold water can not be supplied through the sub UI 54. In this case, the control unit 1 drives the cold water unit 2 in a state where the door is opened, and can control to stop the driving of the cold water unit 2 when the door is closed.

When the door is opened, the control unit 1 closes all the valves for supplying the drinking water to the external dispenser 20 so that the drinking water is supplied to the external dispenser 20 regardless of whether the external dispenser 20 is operated or not. Can be prevented from being supplied.

Accordingly, the controller 1 may control the various components described above according to the detection result of the door opening / closing detector 74. Of course, the control unit 1 may control the above-described various configurations according to the currently powered UI or the activated UI.

This can reduce unnecessary energy wastage and prevent drinking water from being supplied in an unexpected state.

On the other hand, the control unit 1 can control the alarm device 6. That is, when the supply of the drinking water of the set capacity is finished, the alarm device 6 can be informed by sound. Accordingly, even if the user presses the water-taking button 135 and vacates the seat, the user can easily grasp that the drinking water supply is completed through the alarm device 6. Therefore, it is very convenient to use.
