Description

  The present invention relates to a washstand that can be height-adjusted, and more particularly, to a washstand that can be height-adjusted and has a simplified structure using its own weight.

  A washstand with a preset height for using tap water for purposes such as a washbasin is universally installed in a washroom and a public toilet of a general household.

  Such a washstand is fixedly installed on the wall at a height set based on a general adult, so people who are taller or lower than the installed height, especially children, There is a problem in that it is impossible to use a washbasin having a height based on such a general adult. In order to solve these problems, a wash basin has been developed in which a hydraulically or hydraulically operated cylinder is installed at the bottom of the wash basin so that the height can be adjusted.

  Thus, in the case of a wash basin using a hydraulically or hydraulically operated cylinder, the cylinder is divided into an upper part and a lower part, pipes are connected to each of them, and the wash basin is raised and lowered by adjusting a hydraulically operated valve.

  However, when raising and lowering the wash basin by such a method, there is a problem that the piping structure of the wash basin is complicated and repair is difficult. Further, since the structure of the hydraulically operated valve must be complicated in order to raise and lower the wash basin in this way, there is a problem in that the machining operation of the hydraulically operated valve becomes complicated and the manufacturing cost increases. .

  The present invention is for solving the above-described problems, and provides a washstand that can be height-adjusted and can be smoothly raised and lowered using its own weight.

  The wash basin according to the present invention for achieving the above-mentioned problems is connected to a cylinder installed under the wash basin body, a hydraulically operated valve installed in the wash basin body, and a hydraulically operated valve so that inflow water can pass therethrough. A water supply line that is connected to a hydraulically operated valve, a drain line through which effluent water passes, and one end is connected to a hydraulically operated valve, the other end is connected to a cylinder, and the working water that operates the cylinder passes through Includes one working line. Here, the hydraulically operated valve is assembled so that the water supply line, the drainage line, and the operation line are respectively connected to the outside, and the hollow type adjustment cylinder, and each line is assembled by rotation. And a rotary valve spool having an opening formed on the outer surface thereof so as to communicate with the valve.

  Two openings are preferably formed in the outer surface of the rotary valve spool, and the openings communicate with each other through the interior of the rotary valve spool.

  The water supply line, the drainage line, and the operation line are preferably connected to the side surface of the hollow adjustment cylinder at an angle.

  When the washstand is raised, the water supply line and the working line can communicate with each opening formed in the rotary valve spool.

  When the basin is lowered, the drain line and the working line can communicate with each opening formed in the rotary valve spool.

  The working line is preferably located between the water supply line and the drain line.

  When the washstand stops, the communication between the opening formed in the rotary valve spool and the water supply line, the drainage line, and the operation line can be blocked.

  It is preferable that the angle formed by any one of the water supply line and the drain line is substantially the same as the angle formed by the two openings formed in the rotary valve spool.

  The angle formed by the two openings formed in the rotary valve spool is preferably substantially a right angle.

  The wash basin according to the present invention preferably further includes a piston that is connected and fixed from the cylinder to the ground while forming one variable sealed space in the cylinder.

  Preferably, the hydraulically operated valve further includes a button coupled to the rotary valve spool, and the rotation of the rotary valve spool is controlled by pressing the button.

  The wash basin according to the present invention may further include a variable bracket disposed at a lower portion of the wash basin body in a direction parallel to a direction in which the cylinder extends to support movement of the wash basin body.

  Here, the variable bracket is fixed to the lower part of the wash basin body, is supported by the cradle that supports the wash basin body, is connected to the cradle, is movable up and down, and is coupled to the movable base and moves. It is preferable to include a support base that moves the base up and down and installs a bearing between the base and the base to facilitate the movement of the base.

  Here, the bearing is preferably a ball bearing.

  Preferably, the variable bracket further includes a cylinder support fixed to the lower part of the cylinder and connected to the moving table so as to support the cylinder.

  Since the hydraulically operated valve in the washstand according to the present invention includes the hollow type adjustment cylinder and the rotary valve spool, the washstand can be smoothly raised and lowered by these interactions.

  Since the opening formed in the outer surface of the rotary valve spool communicates with the inside, water can be smoothly communicated through the rotary valve spool.

  Since the water supply line, the drainage line, and the operation line are connected to the side surface of the hollow adjustment cylinder at an angle, the washstand is raised, lowered, and stopped accurately by operating the hydraulically operated valve.

  Since the operation line is located between the water supply line and the drainage line and is connected to the hollow adjustment cylinder, it is suitable for raising and lowering the washstand.

  Since the angle formed by any one of the water supply line and the drain line with the working line is substantially the same as the angle formed by the two openings formed in the rotary valve spool, The communication between the valve spools is efficiently performed, and the sink is raised and lowered smoothly.

  Since the button is connected to the rotary valve spool, the rotary valve spool can be more easily operated through the operation of the button.

  Since the variable bracket that supports the movement of the wash basin body includes a bearing to facilitate the movement of the cradle, the descent is smoothly performed even when the wash basin is lowered by its own weight.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. Such examples are merely to illustrate the present invention and the present invention is not limited thereto.

  FIG. 1 is a side view of a wash basin 100 according to an embodiment of the present invention, showing the wash basin 100 fixed adjacent to a wall surface. Such a structure of the washstand is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the washstand of the present invention can be modified to other structures.

  As shown in FIG. 1, the wash basin 100 supplies water to a water supply valve 80 installed in the wash basin body 10 through a water supply pipe (not shown) connected to a water supply pipe 82 and is used through a drain trap 84. Drain the drained water.

  The wash basin body 10 is provided with a hydraulically operated valve 30 so that the height of the wash basin can be adjusted. A water supply line 62 through which the inflow water passes and a drain line 64 through which the outflow water pass are respectively connected to the lower part of the hydraulically operated valve 30. One working line 66 through which the working water for operating the cylinder 90 passes is connected to the hydraulically operated valve 30 at one end and to the cylinder 90 at the other end. In the present invention, the wash basin 100 is raised and lowered using only one working line 66 in this way, so that the structure is greatly simplified and the number of parts used is reduced.

  Since the water supply line 62, the drainage line 64, and the operation line 66 are made of a flexible member, the length thereof is flexibly adjusted by the height change of the wash basin 100, and water can be smoothly communicated.

  The cylinder 90 installed under the sink base body 10 forms one variable type sealed space. Since only one working line 66 is used, only one variable type sealed space of the cylinder 90 is sufficient. One such variable sealed space is formed by a piston 94 that is connected and fixed from the cylinder 90 to the ground, and is located above the piston 94.

  The cylinder 90 installed under the wash basin body 10 changes its volume depending on the working water channel flowing into and out of the upper part, and the piston 94 is fixed to the ground. The main body 10 moves smoothly up and down.

  In order to support the up-and-down movement of the wash basin body 10, the variable bracket 20 is disposed in the lower part of the wash basin body 10 in a direction parallel to the direction in which the cylinder 90 extends. To support. For this purpose, the variable bracket 20 includes a receiving base 22, a moving base 25, a support base 24, a cylinder support base 21, and the like. The variable bracket 20 is firmly fixed to a fixing base 26 attached to the wall surface. Hereinafter, the structure of the variable bracket 20 will be described in more detail with reference to FIG.

  FIG. 2 is a perspective view of the variable bracket 20 according to an embodiment of the present invention, and schematically shows the form of the variable bracket 20 that supports the movement of the wash basin body 10 whose height is adjusted up and down. It is a drawing.

  As shown in FIG. 2, the variable bracket 20 includes a receiving base 22, a moving base 25, a support base 24, and a cylinder support base 21. The cradle 22 is attached to the lower part of the wash basin body 10 (shown in FIG. 1, the same applies hereinafter) to support the wash basin body 10. The moving table 25 to which the receiving table 22 is connected and attached is movable up and down as shown in the arrow direction. Since the cradle 22 is firmly connected to the moving table 25, the basin body 10 is firmly supported regardless of the vertical movement of the moving table 25. Thereby, when the movable stand 25 moves up and down, the wash basin body 10 also moves together.

  The support base 24 surrounded by the mobile base 25 is coupled and fixedly supported by the mobile base 25 so that the mobile base 25 can move smoothly in the vertical direction. As a result, the movable table 25 can move continuously in the vertical direction along the support table 24.

  The enlarged circle in FIG. 2 shows a cross-sectional structure of the support base 24 in which the bearing 245 is installed on the surface facing the mobile base 25 and the mobile base 25 that facilitates the movement. As shown in the enlarged circle of FIG. 2, the bearing 245 is installed between the support base 24 and the moving base 25 so that the moving base 25 can move smoothly. For this purpose, the bearing 245 is fixed to the bearing fixing housing 241. Since the bearing 245 is in close contact with both the support base 24 and the moving base 25, the moving base 25 can move smoothly while passing through the bearing 245. Here, a ball bearing can be used as the bearing 245.

  The cylinder support 21 is fixed to a lower portion of a cylinder 90 (shown in FIG. 1, the same applies hereinafter), and is connected and fixed to the moving table 24 so as to support the cylinder 90. Thereby, the movable stand 24 can be supported stably and the up-and-down movement of the washstand 100 (illustrated in FIG. 1) becomes smooth.

  FIG. 3 is a cross-sectional view of a water pressure actuated valve 30 of a wash basin according to an embodiment of the present invention, and shows an internal cross section of the water pressure actuated valve 30. Although not shown in FIG. 3, a packing can be inserted between the components of the hydraulically operated valve 30 to further improve the adhesion between the components.

  The hydraulically operated valve 30 shown in FIG. 3 has a valve main body 350 having three connecting holes 3501 formed in the lower part thereof, a seat 360 that is positioned in the valve main body 350 and that fixes and supports the hollow adjustment cylinder 300, and a seat 360. It is positioned and fixed above, and is assembled so that the water supply line, the drainage line, and the operation line are connected to the outside through the connection hole 3501, and the hollow adjustment tube 300 is assembled into the hollow adjustment tube 300. A rotary valve spool 310 having an opening 3101 formed on the outer surface so as to communicate with each line by rotation, and positioned directly above the rotary valve spool 310 and coupled to a protrusion 3103 of the rotary valve spool 310. The rotary valve lever 320 is coupled so as to cover the rotary valve lever 320 and is separated at a predetermined interval along the inner peripheral edge. Housing 330 having a pair of locking protrusions 3301 and is coupled with the rotary valve lever 320 includes a valve handle 340 for rotating the same. The rotary valve lever 320 includes pins 3201 that are fixed to springs that are elastic members 3203, and the pins 3201 are radially arranged at the center of the rotary valve lever 320.

  The upper part of the hydraulically operated valve 30 is surrounded by a lower cover 390, an intermediate cover 380, and an upper cover 370 in this order. The intermediate cover 380 and the lower cover 390 are connected to the nut 385, and a spacer 381 is fitted between them, and washers 383 are inserted into both ends thereof.

  Although only two connecting holes 3501 are shown in FIG. 3, three connecting holes 3501 are actually formed. One end of each of the three connection holes 3501 is connected to a water supply line, a drainage line, and an operation line, and the other end is connected to the hollow adjustment cylinder 300. Since the water supply line, the drainage line, and the operation line are connected to the side surface of the hollow adjustment cylinder 300 at an angle, the communication of water is stopped by the change in the position of the opening 3101 due to the rotation of the rotary valve spool 310. You can change the direction of water communication. The operation line is preferably connected to the hollow adjustment cylinder 300 while being positioned between the water supply line and the drainage line so that the washstand can be raised and lowered through the water communication. Two openings 3101 are formed on the outer surface of the rotary valve spool 310 for smooth water communication. The opening 3101 communicates with the inside of the rotary valve spool 310.

  Since the hollow adjusting cylinder 300 and the rotary valve spool 310 are made of a ceramic material, wear due to friction between them can be minimized. Such friction can be further minimized by applying grease between the hollow type adjusting cylinder 300 and the rotary valve spool 310, and the adhesion effect between the two can be further increased by applying the grease. Accordingly, when the rotary valve spool 310 is rotated by the operation of the valve handle 340, the height of the washstand can be adjusted smoothly by passing water in a desired direction without leakage.

  Although not shown in FIG. 3, the hydraulically actuated valve 30 may further include a button connected to the rotary valve spool 310. The button is installed on the wash basin body, and the rotation of the rotary valve spool 310 can be controlled each time the button is pressed. By operating such a button, the rotary valve spool 310 can be operated more easily.

  Hereinafter, the height adjustment process of the wash basin by the operation of the hydraulically operated valve will be described in more detail with reference to FIGS. 4 to 6, for convenience, the variable bracket is omitted to show each line connected to the hydraulically operated valve.

  4 to 6 are schematic views illustrating an operation state of a wash basin according to an embodiment of the present invention. FIG. 4 illustrates a state in which the wash basin 100 is stopped, and FIG. FIG. 6 shows a state where the sink 100 is lowered. In order to explain the operation state of the hydraulically operated valve 30 due to the movement of the wash basin 100, the rotary valve spool 310 and the hollow type adjusting cylinder 300 among the internal components of the hydraulically operated valve 30 are shown on the left side of FIGS. Is shown enlarged.

  As shown in FIG. 4, the rotary valve spool 310 is rotated by the rotation of the hydraulically operated valve 30. In this case, the position of the opening 3101 formed in the rotary valve spool 310 is changed. The angle (α) formed by the two openings 3101 formed in the rotary valve spool 310 is substantially the same as the angle (α) formed by any one of the water supply line 62 and the drain line 64 with the operation line 66. Are identical. As a result, the two openings 3101 communicate with the water supply line 62 and the operation line 66 simultaneously, or communicate with the drainage line 64 and the operation line 66 simultaneously. Here, it is preferable that the angle (α) formed by the two openings 3101 is substantially a right angle. In this case, water can be smoothly communicated by the rotation of the rotary valve spool 310.

  FIG. 4 shows a state in which water communication is blocked by the hydraulically operated valve 30 due to the relative positional relationship between the rotary valve spool 310 and the hollow adjustment cylinder 300. Thereby, the raising and lowering of the washstand 100 are stopped. That is, when the wash basin 100 stops, the opening 3101 formed in the rotary valve spool 310 is disconnected from the water supply line 62, the operation line 66, and the drainage line 64, and the hollow type adjustment cylinder 300. Adjacent to the inner wall. At this time, the opening 3101 is located between the water supply line 62, the operation line 66, and the drainage line 64, so that communication of water is blocked. Since the water supply line 64 connected to the water supply pipe and the operation line 66 connected to the cylinder 90 are filled with water, water pressure acts as shown by the arrows, but the rotary valve spool 310 blocks water communication. Therefore, the washstand 100 is maintained in a stopped state.

  FIG. 5 shows a state where water is communicated by the relative positional relationship between the rotary valve spool 310 and the hollow type adjustment passage 300 and the washstand 100 is raised. When the hydraulic valve 30 is rotated to rotate the rotary valve spool 310 clockwise as indicated by the arrow, the opening 3101 rotates and communicates with the water supply line 62 and the operation line 66. In this case, since the water pressure of the water supply line 62 connected to the water supply pipe is larger than the water pressure of the cylinder 90 connected to the operation line 66, water flows from the water supply line 62 to the operation line 66 side as indicated by the arrow. . As a result, the amount of water in the cylinder 90 connected to the operating line 66 increases, but the inside of the cylinder 90 is sealed by the piston 94, so that the cylinder 90 rises, thereby raising the wash basin body 10 together. In this manner, the water pressure actuated valve 30 is operated to raise the washstand 100. In order to stop the ascent, the hydraulically operated valve 30 only needs to be rotated a little.

  FIG. 6 shows a state in which the wash basin 100 is lowered as a result of water being communicated by the relative positional relationship between the rotary valve spool 310 and the hollow type adjustment cylinder 300, contrary to FIG. 5. When the hydraulic valve 30 is rotated to rotate the rotary valve spool 310 counterclockwise as indicated by the arrow, the opening 3101 rotates and communicates with the operation line 66 and the drain line 64. In this case, since the hydraulic pressure of the cylinder 90 connected to the operation line 66 is larger than the drainage line 64 side, the water in the cylinder 90 is discharged to the drainage line 64 side through the hydraulically operated valve 30. In particular, since the load of the wash basin body 10 acts on the cylinder 90, when the operation line 66 and the drainage line 64 side are communicated, the washstand 100 descends while water in the cylinder 90 is discharged to the drainage line 64 side. . That is, the washstand 100 can be lowered using the weight of the washstand main body 10.

  Thus, since the wash basin body 10 is supported by the variable bracket provided with the bearing, the descent of the wash basin 100 using its own weight instead of water pressure can be performed smoothly. That is, the washstand 10 can be lowered using the washbasin body 10 by efficiently sliding the variable bracket.

  The present invention has been described above with reference to the embodiments. However, various modifications and variations are possible within the technical field to which the present invention belongs without departing from the concept and scope of the claims. One can easily understand.
