1 is a perspective view of a water purifier according to the present invention. This will be described below with reference to Fig.

The water purifier according to the present invention includes a case 2 for forming an appearance, a cork 4 for providing water to the user, and a dial 8 for selecting the type of water to be discharged through the cork 4.

Meanwhile, a lever 7, which can be operated by a user so as to supply water through the cock 4, can be rotatably provided in the case 2.

At this time, the dial 8 includes a fixing part 50 fixed to the case 2 and a rotation part 10 rotatable to the fixing part 50.

Meanwhile, the case 2 includes a stepped step portion 5 and a protruding portion 6 protruding from the stepped portion 5 and exposed to the user. The stepped portion 5 is provided on the front surface of the case 2 so that the upper portion of the front surface of the case 2 is relatively protruded while the central portion of the case 2 is relatively recessed Lt; / RTI >

The stepped portion 5 may be provided with a predetermined curvature so as to be beautiful for the user.

The projecting portion 6 is provided on the stepped surface of the step portion 5 and the cork 4 and the lever 7 can be provided on the projecting portion 6. [ Since the user must place a cup or bottle for receiving water in the lower portion of the cock 4, a predetermined space is required below the cock 4. Further, the lever 7 needs a predetermined space in the locus on which the lever 7 is rotated so that the user can rotate the lever 7. According to the present invention, it is possible to provide a space for using the cork 4 and the lever 7 in the stepped portion 5, so that space efficiency can be improved.

Meanwhile, the fixing portion 50 of the dial 8 and a part of the rotation portion 10 may be provided on the protruding portion 6. At this time, the fixing portion 50 not provided to the protrusion 6 and another portion of the rotation portion 10 may be installed in the case 2 rather than the protrusion 6.

The lower part of the rotation part 10 provided on the protrusion 6 is exposed to the outside as compared with the rotation part 10 not provided on the projection part 6 so that the user can easily lower the lower part of the rotation part 10 So that the rotation unit 10 can be rotated. Therefore, according to the configuration of the present invention, the user can easily access the rotary part 10, and the operation of the rotary part 10 is facilitated, so that the kind of water supplied through the cock 4 can be easily selected.

The present invention may include a user interface unit 90 provided in the case 2 adjacent to the outer circumferential surface of the rotary unit 10. [ The user interface unit 90 may be illuminated differently depending on the rotation of the rotation unit 10 to display the type of water currently supplied from the cock 4. In addition, the user interface unit 90 can provide information on the remaining capacity of the hot water and the cold water stored in the water purifier to the user.

Fig. 2 is an exploded perspective view of the dial, and Fig. 3 is a view showing a state in which the dial is installed in the case. This will be described below with reference to FIG. 2 and FIG.

The dial 8 can be divided into the fixing part 50 and the rotation part 10.

The fixing unit 50 includes a housing 60 coupled to the case 2, a diffusion member 80 accommodated in the housing 60 to diffuse light, And a display window 70 provided on the front surface of the projecting piece 74. [

The housing 60 may have a ring-shaped rib 64 protruding by a predetermined height. The rotation part 10 may be pivotally coupled to the inner surface of the rib 64 by pressing in the radial direction.

Since the rotation unit 10 is rotatably coupled to the outside of the housing 60 rather than the center of the housing 60, the rotation unit 10 can be stably coupled to the housing 60.

The diffusion member 80 may be made of translucent glass or plastic to diffuse light emitted from the opposite side of the housing 60. Light emitted from the housing 60 can be directed in a specific direction, but light can be diffused through the diffusion member 80 to spread the light to the dial 8 as a whole.

A plurality of first magnetic bodies 82 having magnetic properties may be provided in the diffusion member 80 at a plurality of positions. At this time, the first magnetic bodies 82 are arranged to have an angle of 90 degrees with respect to each other, and the positions of the first magnetic bodies 82 may correspond to the positions indicating the integer, cold water, and hot water in the user interface unit 90.

The protruding piece 74 is made of a material through which light can pass, and can provide light to the display window 70. The front surface of the projecting piece 74 may have a planar structure having a flat front surface so that the display window 70 can be easily installed.

Particularly, the protruded piece 74 is made of a transparent material, and the display window 70 is protruded from the housing 60 by a predetermined height and is located more adjacent to the user, As shown in FIG.

Since the protrusion piece 74 and the display window 70 are fixed to the housing 60 so that they can not move, the image formed on the display window 70 is constantly displayed to the user even when the rotation unit 10 rotates .

The rotary unit 10 includes a first rotary member 40 rotatably coupled to the housing 60 by a ball bearing 42, a second rotary member 30 surrounding the first rotary member 40, A third rotary member 20 provided inside the second rotary member 30 and a cover 12 forming an outer appearance of the dial 8.

A ball bearing 42 is provided on the outer side of the first rotating member 40 to guide movement of the first rotating member 40 along a plurality of receiving grooves 68 formed on the inside of the rib 64 can do. Since the ball bearing 42 is intermittently inserted into the receiving groove 68 as the rotating part 10 is rotated, the user can feel that the rotating part 10 is rotated normally.

Meanwhile, a plurality of ball bearings 42 may be provided on the outer circumferential surface of the first rotary member 40, and four ball bearings 42 may be installed as shown in FIG. The ball bearings 42 may be arranged so as to be evenly distributed as a whole in order to stably install the first rotary member 40 on the ribs 64. [

The first rotating member 40 is provided with an elastic supporting member 44 for elastically supporting the ball bearing 42 protruded outward in the radial direction. The elastic support member 44 may have a predetermined space inward to support the ball bearing 42 so as to protrude from the outer surface of the first rotary member 40 with a predetermined force.

Since the first rotating member 40 is installed so as to surround the outer surface of the rib 64 and the inner surface of the first rotating member 40, (40) can be prevented from being detached from the rib (64). The second rotary member 30 has two front surfaces extending generally rearwardly from both ends of the front surface and one extending surface extending toward the outer surface of the rib 64, The extending surface may extend toward the inner surface of the first rotating member 40.

Also, the second rotary member 30 is made of a material that does not allow light to pass therethrough, thereby preventing the specific coupling structure of the first rotary member 40 and the housing 60 from being exposed to the user. Therefore, the user can feel the impression of the beauty of the present invention without recognizing the complicated structure.

Of course, the second rotary member 30 is fixed to the first rotary member 40 and is coupled to the ribs 64 at a predetermined interval, so that the first rotary member 40 and the second rotary member 30 can rotate together.

A third rotary member 20 rotatable with the second rotary member 30 may be provided on the inner side of the second rotary member 30. The outer circumferential surface of the third rotary member 20 can be fixed in contact with the inner surface of the second rotary member 30 and the inner surface of the third rotary member 20 can be spaced apart from the protruding piece 74 by a predetermined distance, Can be rotated together with the rotation of the first rotary member (40) without being interfered with the first rotary member (74).

The third rotary member 20 is made of a material through which light can pass, and can transmit light irradiated from the housing 60 toward a user.

In particular, the third rotary member 20 may have a step 22 whose height gradually decreases toward the inside, and a plurality of the step 22 may be provided. That is, the step 22 is provided in a plurality of steps so that the user can concentrate on the image transmitted from the display window 70 located at the center of the third rotary member 20. [ That is, the image transmitted from the display window 70 can be more efficiently transmitted to the user due to the shape of the third rotary member 20.

The cover 12 may be made of a material that can be rotated by a user's operation and light can pass through. The outer surface of the cover 12 may be formed with angled corners or irregularities so that the user can rotate the cover 12 easily. The light irradiated from the housing 60 and moved to the cover 12 can be diffused from the outer surface of the cover 12 by the shape of angled corners or concavities on the outer surface of the cover 12, The lightness of the dial 8 can be improved by the light irradiated in various directions.

The cover 12 closes the front of the second rotating member 30 and the third rotating member 20 and the user rotates the second rotating member 30 and the third rotating member 20 directly You can prevent access. That is, the user can simultaneously rotate the second rotary member 30 and the third rotary member 20 by rotating the cover 12, and it is necessary to approach the specific configuration of the dial 8 The durability of the dial 8 can be improved.

4 is a view showing a coupling structure of the first rotating member and the housing. This will be described below with reference to Fig. The diffusion member is omitted for convenience of explanation in Fig.

The ball bearing 42 is provided on the outer peripheral surface of the first rotary member 40 and the receiving groove 68 coupled with the ball bearing 42 is formed on the inner surface of the housing 60.

Since the first rotary member 40 is rotatably coupled to the inner side surface of the housing 60 while pressing the inner side surface of the housing 60 in the radial direction, .

Since the outer circumferential surface of the first rotary member 40 is entirely supported by the ribs 64, the area of the first rotary member 40 supported by the housing 60 is increased, The fastening force of the member 40 and the housing 60 can be improved.

Therefore, a hollow space may be provided at the center of the first rotary member 40, and a display window 70 may be provided to provide a specific image to the user, as shown in FIG.

5 is a view showing the first rotating member, the housing and the diffusion member. This will be described below with reference to FIG.

The first rotating member 40 may be provided with a second magnetic body 46 having a magnetic property on a surface adjacent to the diffusion member 80. At this time, the second magnetic body 46 is disposed opposite to the polarity of the first magnetic body 82 to generate attraction with the first magnetic body 82.

The first magnetic member 82 may be installed only on one portion of the first rotating member 40.

When the first magnetic member 82 is adjacent to the second magnetic member 46 as the first rotating member 40 rotates, the first rotating member 40 Can be stopped.

At this time, it is preferable that the position where the second magnetic body 46 is installed is a position adjacent to the menu related to the purified water, cold water, and hot water shown in the user interface unit 90. That is, while the first rotating member 40 is stopped at a position where the plurality of second magnetic bodies 46 are located, the user can recognize that the user rotates the rotating unit 10 to select a kind of water desired to be supplied .

6 is a view for explaining the flow of light irradiated by the LED in the present invention. This will be described below with reference to Fig.

A plurality of LEDs (LEDs) 86 and 88 for irradiating light may be installed behind the housing 60. At this time, the LED is a light source using an electroluminescence phenomenon of an injection type electroluminescence which emits by a current.

The plurality of LEDs 86 and 88 may include an LED 86 disposed at the center of the housing 60 so as to irradiate the protrusion 74 with light, And an LED 88 installed at one side of the housing 60 so as to be able to perform the operation.

The LEDs 86 installed in the center of the housing 60 can irradiate light toward the display window 70 from the center of the housing 60. The light irradiated from the LED 86 can be moved to the outside through the cover 12 after passing through the projecting piece 74 and the display window 70. [ The display window 70 and the protruding pieces 74 remain fixed even when the rotation unit 10 rotates. Therefore, when the light emitted from the LED 86 passes through the display window 70, the image of the display window 70 provided to the user can be kept constant without being rotated.

An LED 88 disposed at one side of the housing 60 irradiates the third rotary member 20 with light. Since the third rotary member 20 is provided with the plurality of stepped portions 22, the light emitted from the LED 88 can be reflected and diffused in various directions at the step 22. Therefore, unlike the light irradiated through the display window 70, the light transmitted through the third rotary member 20 can produce various shapes.

Meanwhile, since the second rotary member 30, which finishes the outside of the third rotary member 20, is made of a material through which light does not pass, the light irradiated through the LED 88 is transmitted through the second rotary member 30, (30) and can not pass through the third rotary member (20). Therefore, the shape of the second rotary member 30 can be exposed to light by the light by the LED 88.

7 is a diagram showing a change of the user interface unit according to the rotation of the rotation unit in the present invention. Hereinafter, the operation of the present invention will be described using FIG. 7 and the above-described drawings.

FIG. 7 shows a state in which purified water, which is filtered water at room temperature, is supplied through the cock 4. In FIG. 8, the cold water is supplied through the cock 4, The hot water is supplied through the

7 to 9, windows corresponding to the constants, cold water, and hot water of the user interface unit 90 are activated or turned on according to the kind of water supplied through the cock 4, Can be transmitted. For example, as shown in FIG. 7, when the purified water is supplied through the cock 4 by the rotation of the dial 8, it is preferable that the window relating to the hot water and the cold water is inactivated.

The cock 4 is a single cock, through which pure water, cold water and hot water can be selectively supplied. The type of water discharged from the single coke can be selected through the dial. Then, a window corresponding to the selection of the dial may be turned on.

Therefore, the user can intuitively know what kind of water can be supplied from the single cock 4 through the lighting of the user interface 90, which is very convenient to use.

It is possible to provide a water purifier which is very simple and beautiful in appearance and is easy to use through the single coke 4, the dial 8 and the user interface 90.

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, when the user desires to receive cold water in the state of FIG. 7, the dial 8 may be rotated clockwise.

At this time, the fixing portion 50 is stopped and the rotation portion 10 is rotated clockwise. At this time, the user rotates the cover 12 clockwise after grasping the hand on the cover 12. Then, the cover 12, the second rotating member 30, the second rotating member 30, and the first rotating member 40 are simultaneously rotated in the clockwise direction.

The ball bearings 42 are moved along the clockwise direction while being repeatedly inserted into or drawn out from the plurality of receiving grooves 68 formed in the ribs 64.

When the first magnetic member 82 and the second magnetic member 46 are adjacent to each other while the first rotary member 40 is moved, the first magnetic member 82 and the second magnetic member 46 are positioned between the first magnetic member 82 and the second magnetic member 46 Sufficient manpower can be generated. At this time, the user must exert a relatively large force to rotate the rotation unit 10 as compared with when there is no attraction force. Therefore, the user can feel the rotation of the rotary part 10 sufficiently by the resistance force by such attraction force, and can stop the rotation.

At this time, the position where the second magnetic body 46 is installed is provided adjacent to the window indicating the cold water, so that the user can recognize that the first rotary member 40 has been operated so that the cold water is supplied from the cock 4 .

On the other hand, when the user wishes to receive hot water through the cock 4, the rotation unit 10 is rotated counterclockwise. Since this operation is the same as the operation according to the clockwise rotation described above, a detailed description will be omitted.

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 the on / cold water off, the operation of the cooling apparatus such as the heater for heating the hot water tank provided in the case 2 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 4 even if the user rotates the dial 8. 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.

The operation of the cooling device for cooling the cold water tank provided in the case 2 can be stopped when the user selects the cold water off. Also in this case, the display window showing the remaining capacity of the cold water may be turned off.

If cold water off is selected, cold water may not be supplied through the cock 4 even if the user rotates the dial 8. 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 2 can be stopped. In this case, the display window showing the remaining capacity of the hot water may be turned off.

If the hot water off is selected, hot water may not be supplied through the cock 4 even if the user rotates the dial 8. 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.

10 and 11 are views showing the present invention from one side. This will be described below with reference to Figs. 10 and 11. Fig.

In the state shown in Fig. 10, the user can rotate the lever 7 counterclockwise to discharge the water through the cock 4. At this time, the user can press the cork 4 in a state in which a cup, a bottle, or the like is in contact with the side surface of the lever 7.

11, the user can rotate the lever 7 counterclockwise in the state shown in FIG. 10 to discharge the water through the cock 4, as shown in FIG.

11, when the lever 7 is rotated, since the lever 7 is not positioned below the cock 4, a space for placing a cup, a bottle, or the like in the lower portion of the cock 4, Can be increased.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
