However, the following examples are merely to be described by way of example in order to easily convey the principle of operation of the present invention is not intended to limit the scope of the present invention.

Figure 1 according to the present invention in accordance with the hydraulic pressure operation by the water channel switching valve 20 is a three-way valve in accordance with the hydraulic pressure tube 32 of the elastic material with a constant strength of the elastic material holding tube 34 is contracted and It shows an installation state cross-sectional structure of the sink height adjustment device that can be adjusted by raising and lowering the sink (10) to a predetermined height while inflated. In addition, Figure 2a and Figure 2b shows the operating state of the tube moving housing 40 which is elevated by the housing guide support 33 and the housing passage pedestal 35 of the vanity height adjusting device according to the present invention.

In addition, Figure 3 shows the combined state of the three-way channel switching valve 20 for operating the lifting operation of the sink 10 in the hydraulic operation in accordance with the present invention, and Figures 4a and 4b is a channel switching valve according to the present invention The drainage connecting hole 23a and the tube access hole 22a or the tube access hole 22a through which the channel connecting groove 26 recessed in the upper plate 25 through the operating structure of the 20 passes through the valve lower plate 27. And it is located in the direct inlet hole (22a) to adjust the waterway direction, Figure 4a is the water from the power tube 32 connected to the tube entry hole (22a) is the height through the drain connection hole (23a) 4B is an operation state to discharge to the control pipe 30, Figure 4b is the water flowing from the straight pipe 14 connected to the direct connection hole 21a flows into the power tube 32 through the tube entrance hole (22a). It shows each operating state to make it possible.

And 5a to 5c is a cross-sectional view showing the operating state of the non-return connection pipe 42 is installed between the height control pipe 30 and the drain pipe 15 for preventing the back flow of the drain pipe 15 according to the present invention. 5B shows a float spacer 45 having a predetermined height integrally protruding from the bottom of the backflow prevention connection pipe 42 so that the space between the backflow prevention connection pipe 42 and the backflow prevention booth 43 can be spaced apart from each other. 5c illustrates a form in which the knit spacer protrusion 45 integrally protrudes from the bottom surface of the backflow prevention float 43.

In particular, the backflow prevention blister 43 applied to the present invention is a triangular structure in which the inside is hollow and narrowed toward the top to seal the drainage pipe 15 so that the height control pipe 30 through the drainage pipe 15. As the odor is prevented from flowing backward, and the backflow prevention float 43 is automatically floated by the buoyancy force of the water falling from the height control pipe 30 so that the water is smoothly discharged into the drain pipe 15.

In more detail, first, the sink 10 is a room wall so that the height can be freely adjusted by the power holding pipe 34 which is length-displaced together in accordance with the contraction and expansion of the power tube 32 by the hydraulic operation. Separated from the (50) is installed such that the force tube 32 and the force holding tube 34 is located on the built-in tube moving housing (40). Of course, the sink 10 is formed with a drain 11 for discharging water at the bottom of the water pipe 14 is connected to the faucet 13 from the interior wall (50). However, unlike a conventional wash basin, the valve control port 24 for adjusting the channel direction of the water channel switching valve 20 according to the present invention is installed on the upper side or one side of the sink 10.

Particularly, the vanity height adjusting device of the present invention allows the power tube 32 to be expanded by introducing water from the straight pipe 14 into the power tube 32 by adjusting the water channel direction through the direction operation of the water channel switching valve 20. It is possible to raise the sink 10, in which case the maximum expansion size (length) of the power tube 32 is the rising height of the sink (10). On the contrary, by discharging the water filled in the power tube 32 through the other direction operation of the channel switching valve 20 to the height control pipe 30 connected to the drain pipe 15 instead of the water pipe 14. When the backing tube 32 is contracted, the raised sink 10 may be lowered down again.

As such, the booster tube 32 which raises or lowers the height of the sink 10 while expanding and contracting in accordance with the channel (water pressure) direction change of the channel switching valve 20 is lower than the drain 11 of the sink 10. It is positioned so as to be wrapped around the outer side of the height control tube (30) installed to enable the length displacement, the position of the elastic tube and the force counterbalanced with the weight of the wash basin (10) outside the force tube (32) That is to say, such as the force tube 32, the force retention tube 34 of excellent rubber material is positioned. Of course, the lifting operation of the wash basin 10 is basically acted by the inflow and discharge of water to the power tube 32, the height control pipe 30 of the center is a multi-joint structure of the antenna sink (10) According to the lifting operation of the lifting pipe 15 together with respect to the lifting freely adjustable.

In addition, such a force tube 32 and the force maintaining tube 34 is configured to be embedded in the cylindrical tube moving housing 40, the upper and lower sides of the center, including the height adjustment pipe 30, the tube moving housing ( 40, the upper side is integrally structured with the valve operation retainer 31 coupled to the bottom of the sink (10). Particularly, the pipe moving housing 40 is freely stably freely lifted through the housing guide support 33 by allowing the housing guide support 33 fixed to the interior wall 50 to be moved to the outside of the middle portion thereof. Can be moved. In particular, the power maintaining tube 34 is preferably used in the form of a corrugated pipe having a certain strength of elasticity, but in some cases, such as the height control pipe 30, various applications in the form of an antenna-like multi-joint that can be displaced in length Of course it is possible.

That is, the housing guide support 33 is fixed to the indoor wall 50 in one side of the bracket structure, preferably a part fixed to the indoor wall 50 is separated to both sides by a stable coupling with the indoor wall 50 The state can be maintained. Of course, the opposite side of the circular shape is not the size that tightly secures the tube moving housing 40, but should be a size that can be stably passed up and down without relatively large swing.

And the lower side of the pipe moving housing 40, the housing passing base so that the power tube 32 and the power maintenance tube 34 supporting the wash basin 10 at a predetermined height with respect to the interior wall 50 can be stably supported. 35 is positioned, that is, one side of the housing passing base 35 is inserted into the tube moving housing 40 and coupled to each of the force tube 32 and the force maintaining tube 34, respectively, on the other side. One side is fixed to the interior wall 50 similarly to the housing guide support 33. Of course, the tube moving housing 40 is supported as it can be lifted and lowered together in accordance with the expansion and contraction of the force tube 32 in the fixed state in which the housing passage support 35 is inserted into the lower side as shown in FIG. Guide groove 41 is formed to be cut to a predetermined length in accordance with the lifting range of the sink (10).

Particularly, in the vanity height adjusting device of the present invention, the minimum height of the height adjusting member 30 can be maintained between the housing passage support 35 and the power tube 32 in the pipe moving housing 40. 36 is installed, which ensures that the minimum contraction length of the sink 10 is maintained while the contraction length is protected when the force tube 32 and the force maintaining tube 34 are contracted downward.

In addition, the vanity height adjusting device of the present invention is automatically floated in accordance with the buoyancy of the water between the height control pipe 30 and the drain pipe 15 so that the water is smoothly discharged to the drain pipe 15, and the discharge of water is stopped freely The backflow prevention connection pipe 42 is provided with a backflow prevention loop 43 to prevent odors from flowing back from the drainage pipe 15. The top of the bottom of the backflow prevention connection pipe 42 has a height of the protrusions having a predetermined height ( 45 is protruded to prevent the backflow preventer 43 is in direct contact with the bottom of the backflow prevention connection pipe 42.

That is, when the backflow prevention blister 43 is in direct contact with the upper portion of the bottom of the backflow prevention connection pipe 42 and does not maintain a predetermined gap, the backflow prevention braid by water pressure from the height control pipe 30 ( 43) to prevent the injuries to be prevented by a predetermined gap by the float spacers (45). Of course, the float spacers 45 may be integrally formed on the bottom surface of the backflow prevention blister 43 instead of the bottom of the backflow prevention connection pipe 42 as shown in FIG. 5C, and in this case, the backflow prevention float ( 43 is a triangular pyramid shape of which the bottom is open, and the knitting spacers 45 protrude a predetermined length on the bottom four sides thereof and may be seated on the bottom of the backflow preventing connection pipe 42. Of course, the water from the backflow prevention connection pipe 42 may pass between the float separation protrusions 45 of a predetermined height even if the backflow prevention loop 43 is not injured and may be discharged to the drain pipe 15.

In addition, the reverse flow prevention connection pipe 42 has a narrow triangular upper shape and a lower portion connected to the drain pipe 15 is wider than an upper portion to which the height control pipe 30 is connected, and the drain pipe 15 is the counter flow. It is inserted deeper than the height of the protruding height of the spaced projections 45 to the center of the bottom portion of the prevention connection pipe 42 is fixed. In addition, in the case of the backflow prevention blister 43 shown in FIGS. 5A and 5B, a drain pipe connection groove 44 having a predetermined depth is formed at the center of the bottom portion which is in direct contact with the upper side of the drain pipe 15. The degree of sealing of the fruit can be raised. Of course, the inner diameter of the drain pipe connecting groove 44 grooved at the center of the bottom of the backflow prevention blister 43 is naturally larger than the outer diameter of the drainage pipe 15, which is the outside of the backflow prevention bluff 43 and the height adjusting pipe. It is a matter of course that the size is adjusted to be formed according to the separation gap maintained between the inner side of (30).

On the other hand, the channel switching valve 20 is applied to the sink height adjustment device of the present invention, as shown in Figure 3, the direct inlet hole (21a) and tube access hole (22a) and drain connection hole (23a) is formed respectively The valve lower plate 27 connected to the direct connector 21b on one side of the pipe 14, the tube connector 22b on the upper side of the power supply tube 32, and the drain connector 23b on the upper side of the height control pipe 30, and a valve control port. According to the operation of (24), the water inlet hole 21a and the tube outlet hole 22a are opened to introduce water into the power tube 32, or the tube outlet hole 22a and the drain connection hole ( A valve lower plate 25 in which a channel connecting groove 26 is recessed at a bottom thereof to open 23a) to discharge water from the boost tube 32 to the height control pipe 30 connected to the drain pipe 15. Is made of a combination of

That is, the water pipe 14 and the water pipe 14 for supplying water to the valve lower plate 27 through which the three water inlet holes 21a, the tube access hole 22a, and the drain connection hole 23a pass. The power supply tube 32 into which the water supplied to the inlet flows into and expands is connected to the height control tube 30 through which the water filled in the power supply tube 32 is discharged, and formed on the valve lower plate 27. By operating the valve control mechanism 24 with the valve upper plate 25 externally exposed toward the sink 10 with respect to the two channel holes, connecting only two channel holes (reference numerals 21a and 22a or 22a and 23a) at the corresponding positions. The power tube 32 may be expanded and contracted by allowing the inlet and outlet of water to be formed around the power tube 32. This results in the sink 10 being able to adjust the height by the water pressure due to the contraction and expansion of the power tube 32 by the manipulation of the channel switching valve 20.

As described above, the hydraulic actuating vanity height adjusting device of the present invention is a three-way valve, and the upper part separated from the interior wall while the power supply pipe is displaced lengthwise by expansion and contraction of the power tube by adjusting the waterway direction of the drain opening / closing valve.
