Description

A valve disc having a plurality of grooves or holes and a valve assembly including the same

The present invention relates to a disk of a valve and a valve assembly including the same. In detail, it relates to a bidet valve disk and a bidet valve assembly including the same, which can increase the flow rate sprayed during body washing while performing nozzle cleaning of the bidet.

Bidet (bidet) refers to an instrument device for locally washing the user's body after defecation, such as feces and urine. Recently, interest in hygiene has increased along with convenience of use, and bidets are widely distributed and are also used for medical purposes.

Bidets can be largely classified into electronic bidets and mechanical bidets. The electronic bidet controls the water pressure, quantity, and other functions of sprayed washing water using electric power. In addition, the electronic bidet may provide various additional functions other than the essential functions of the bidet, such as controlling the temperature of the sprayed washing water and the temperature of the toilet seat. However, the electronic bidet has disadvantages such as high manufacturing cost and not easy maintenance compared to the mechanical bidet.

The mechanical bidet can control the water pressure using a valve without supplying power. Since mechanical bidets operate without power supply, they provide only monotonous functions compared to electronic bidets. However, it is intuitive to use, easier to maintain than electronic bidets, and has excellent durability.

Due to these advantages, the elderly who require only simple functions tend to prefer mechanical bidets rather than electronic bidets. In addition, in developing countries or underdeveloped countries where constant power supply is not easy, mechanical bidets tend to be preferred over electronic bidets, and mechanical bidets, which are easy to maintain even in public facilities used by an unspecified number of users, may be more suitable.

As described above, the mechanical bidet uses a valve or valve assembly to control the sprayed water pressure and quantity. Recently, a valve assembly has been developed to perform spraying for washing a user's body as well as spraying for cleaning a spray nozzle using a valve assembly.

The problem to be solved by the present invention is to provide a bidet valve assembly having a structure in which washing water for nozzle cleaning is automatically sprayed when a dial is operated for a user's body washing, that is, anal washing or female washing.

Another object of the present invention is to provide a valve assembly having a structure in which cleaning water for nozzle cleaning can be sufficiently sprayed.

Another object of the present invention is to provide a valve assembly capable of adjusting the spray flow rate of washing water according to the rotation angle of the dial and, in particular, providing a very strong spray flow rate according to the user's selection.

Another problem to be solved by the present invention is to provide a valve disc used in the above bidet valve assembly.

The first disk first flow hole 311 and the first disk second flow hole 312 may have a circular shape on a plane, but the present invention is not limited thereto. The planar size of the first flow hole 311 of the first disk may be smaller than the planar size of the second flow hole 312 of the first disk.

In some embodiments, first disk 300 may further include a center pad portion 355 . The center pad part 355 appropriately controls the space volume of the passage space F3 formed by the first disk 300 and allows the dial 200 to rotate smoothly in close contact with the first disk 300. may be provided. In addition, the lower surface of the first disk 300 may be substantially flat except for the first flow hole 311 of the first disk and the second flow hole 312 of the first disk.

The second disk 400 may be disposed lower than the first disk 300 . The size of the second disk 400 on a plane may be larger than that of the first disk 300 on a plane. The second disk 400 selectively blocks fluid flowing downward through the first disk first flow hole 311 and/or the first disk second flow hole 312 of the first disk 300. It can function like a plate or blocking plate. The second disk 400 may be made of a material such as metal, ceramic, or synthetic resin. The second disk 400 may have a substantially circular shape in plan view. The center of the second disk 400 may be aligned with the center of the first disk 300, for example, the center of rotation.

The second disk 400 includes the second disk first flow hole 411 and the second disk second flow hole 412, the second disk first flow path groove 431 and the second disk second flow path groove. (432) may be further included.

The second disk first flow hole 411 and the second disk second flow hole 412 may be provided in plurality. For example, the second disk first passage hole 411 includes the 1-1 passage hole 411a and the 1-2 passage hole 411b, and the second disk second passage hole 412 includes the second passage hole 411a. A 2-1 passage hole 412a and a 2-2 passage hole 412b may be included.

An arbitrary reference line GL passing through the center of the first disk 300 or the second disk 400, for example, the first disk first flow hole 311 of the first disk 300 or the first disk GL in an initial state. Based on the reference line GL passing through the second flow hole 312 , the second disk 400 may be divided into a first area on one side and a second area on the other side. The first region and the second region may have substantially symmetrical shapes with respect to the reference line GL. That is, the two second disk first passage holes 411, the two second disk first passage grooves 431, the two second disk second passage holes 412, and the two second disk second passage grooves 432 may be provided as a pair, one each in the first region and the second region, and may have a mutually symmetrical shape.

Specifically, the second disk 1-1 passage hole 411a and the second disk 1-2 passage hole 411b may be located apart from each other by substantially the same distance based on the center of the second disk 400. can In some embodiments, the separation distance from the center of the first disk 300 to the first flow hole 311 of the first disk is from the center of the second disk 400 to the first flow hole 411 of the second disk. It may be substantially equal to the separation distance, or may have a separation distance difference within about ±10%, or about ±5%.

In addition, when the second disk 400 has a left-right symmetrical shape, the second disk 1-1 passage hole 411a and the second disk 1-2 passage hole 411b are the same with respect to the reference line GL. It may have a separation angle (α1). The first separation angle α1 may be in a range of about 10 degrees to about 20 degrees, or about 14 degrees to about 18 degrees. That is, the 1-1 passage hole 411a and the 1-2 passage hole 411b may be circularly arranged at an angle of about 20 degrees to 40 degrees, or about 28 degrees to 36 degrees.

The second disk 1-1 passage hole 411a and the second disk 1-2 passage hole 411b are fluid paths for cleaning the first injection nozzle (not shown) and the second injection nozzle (not shown) at the same time. Alternatively, the 1-1 passage hole 411a and the 1-2 passage hole 411b may provide a fluid path for cleaning the first injection nozzle and the second injection nozzle, respectively.

Similarly, the second disk 2-1 passage hole 412a and the second disk 2-2 passage hole 412b may be spaced substantially the same distance apart from the center of the second disk 400 . That is, the 2-1 passage hole 412a and the 2-2 passage hole 412b may be circularly arranged. In an exemplary embodiment, the 2-1 passage hole 412a is sprayed to a first injection nozzle (not shown) through the 2-1 discharge passage part 122b and is used for cleaning the anus, and the 2-2 passage The hole 412b may be sprayed to a second spray nozzle (not shown) through the 2-2 discharge passage 122b and used for female washing.

At this time, the minimum separation angle between the first passage hole 411 of the second disk and the second passage hole 412 of the second disk, for example, the second separation angle α2, may be in the range of about 70 degrees to about 80 degrees. there is. As a non-limiting example, when the second disk 400 has a left-right symmetrical shape, the circular arrangement angle of the second disk 2-1 passage hole 412a and the second disk 2-2 passage hole 412b is 180 , and the sum of the first separation angle α1 and the second separation angle α2 may be substantially 90 degrees. In addition, the first flow holes 411 of the second disk and the second flow holes 412 of the second disk are spaced apart from the center of the second disk 400 by substantially the same distance, or ±10%, or It can only have a separation distance difference within ±5%. That is, according to the degree of rotation of the first disk 300, the first flow hole 311 of the first disk may overlap both the first flow hole 411 of the second disk and the second flow hole 412 of the second disk. so that they may all have substantially the same turning radius. On the other hand, the first disk second flow hole 312 may be formed at a rotation radius position that cannot overlap the second disk first flow hole 411 and the second disk second flow hole 412 in any case.

As will be described later, the second disk first flow hole 411 contributes to the flow of fluid flowing to the first discharge channel portion 122a, and the second disk second flow hole 412 is the second discharge channel portion ( 122b) can contribute to the flow of the fluid. The second disk first flow hole 411 and the second disk second flow hole 412 may have a circular shape on a plane, but the present invention is not limited thereto. The planar size of the first flow hole 411 of the second disk may be smaller than the planar size of the second flow hole 412 of the second disk. The planar size of the first flow hole 411 of the second disk may be substantially the same as the planar size of the first flow hole 311 of the first disk, but the present invention is not limited thereto.

The upper surface of the second disk 400 may have a first flow path groove 431 of the second disk and a second flow path groove 432 of the second disk. Unlike the flow holes 411 and 412 , the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk may not have a shape penetrating the second disk 400 . The first flow path groove 431 of the second disk may be connected to the first flow hole 411 of the second disk, and the second flow path groove 432 of the second disk may be connected to the second flow hole 412 of the second disk. .

Hereinafter, the second disk first flow hole 411 is located in, overlaps with, or forms a part of the second disk first flow groove 431, and the second disk second flow hole 412 is formed in the second disk first flow hole 431. It is understood that, whether located within or overlapping the disc second flow path groove 432, it forms part of the groove.

When the second disk 400 has a left-right symmetrical shape, the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk may be provided as a pair. More specifically, the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk may be provided as a pair by being disposed one by one in the first area and the second area.

In an exemplary embodiment, the first passage groove 431 of the second disk may have a shape extending substantially in a radial direction or a shape including such a portion. The first flow path groove 431 of any second disk, for example, the first flow path groove 431 of the second disk on the right side of FIG. 7 may have a shape in which the width decreases and the depth decreases in one rotational direction, for example, in a clockwise direction. . In addition, the second disk first flow hole 411 may be located at an end of the second disk first flow path groove 431 in the other rotating direction (ie, counterclockwise direction), for example, at the left end. That is, the depth of the first flow path groove 431 of the second disk gradually increases and then may be penetrated by the first flow hole 411 of the second disk.

For example, the first flow path groove 431 of any second disk has a planar shape.

It may have a shape such as or a shape symmetrical thereto. In some embodiments, a bottom surface (or a basal surface) of the first flow path groove 431 of the second disk may be inclined downward toward the first flow hole 411 of the second disk. That is, the depth of the first flow path groove 431 of the second disk may gradually increase toward the first flow hole 411 of the second disk.

Also, in an exemplary embodiment, the second disk second flow path groove 432 includes a portion extending in a substantially rotational direction (eg, the first groove portion 432-1) and a portion extending in a radial direction (eg, the second groove portion 432-1). It may have a shape including a groove portion 432-2. Accordingly, the second flow path groove 432 of the second disk may have a partially bent shape. The second flow path groove 432 of the second disk may not be fluidly connected to the first flow path groove 431 of the second disk.

For example, the first groove portion 432-1 of the second flow path groove 432 of the second disk on the right side of FIG. 7 may have a shape in which the width increases and the depth increases in one direction of rotation, for example, in a clockwise direction. In addition, the clockwise end of the first groove portion 432-1 is connected to the second groove portion 432-2, and the end portion 432e in the direction away from the center C of the second groove portion 432-2 has a second groove portion 432-2. A two-disc second flow hole 412 may be located.

Specifically, the first groove portion 432 - 1 may have a shape extending substantially in a rotational direction or a circumferential direction based on the center of the second disk 400 . In addition, the second groove portion 432-2 is connected to the first groove portion 432-1, extends in a radial direction based on the center of the second disk 400, or at least connects with the first groove portion 432-1. It may have a shape extending in a crossing direction. Accordingly, the second flow path groove 432 of the second disk may have a substantially 'L' shape in plan view. More specifically, any second disk second flow path groove 432 is flat

It may have a shape such as or a shape symmetrical thereto.

In some embodiments, the bottom surface (or base surface) of the first groove portion 432-1 slopes downward toward the second groove portion 432-2, and the bottom surface of the second groove portion 432-2 is at least partially The second disk may be inclined downward toward the second passage hole 412 and then have a flat shape.

The second flow path groove 432 of the second disk may be connected to or overlap the second flow path hole 412 of the second disk. Specifically, the second groove 432 - 2 may be connected to or overlap the second flow path hole 412 of the second disk. 7 and the like illustrate a case where the second flow path hole 412 of the second disk is located in the area formed by the second flow path groove 432 of the second disk from a plan view, but in another embodiment, from a plan view The second disk second passage hole 412 is formed in an area other than the second disk second passage groove 432, and the second disk second passage hole 432 and the second disk second passage hole 412 are in the horizontal direction. may be fluidly connected to That is, unlike the present embodiment, the second flow path hole 412 of the second disk is not recognized from a plan view, and only the second flow path groove 432 of the second disk is recognized, and the second flow path hole 412 of the second disk is It may be recognized only from the bottom side.

An imaginary straight line D connecting the center C of the second disk 400 and the center of the first flow hole 411 of the second disk is the starting point 432s of the second flow path groove 432 of the second disk. ), that is, aligned with the starting point, or overlapping. Through this, as will be described later, in the second state, fluid can be injected into the second flow path groove 432 of the second disk through the second flow hole 312 of the first disk.

In addition, an imaginary straight line E extending radially from the center C of the second disk 400 connects the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk. all can pass Through this, a third state may be formed as will be described later. This will be described later.

The maximum depth and maximum width of the first passage groove 431 of the second disk may be smaller than the maximum depth and maximum width of the second passage groove 432 of the second disk. For example, in a cross section cut along a certain imaginary radial direction straight line E, that is, a cross section cut so that both the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk appear. , the depth and width of the first flow path groove 431 of the second disk may be smaller than the depth and width of the second flow path groove 432 of the second disk.

The shape and arrangement of the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk will be described in detail.

The shape angle β1 from the start point 431s to the end point 431e of the second disk first flow path groove 431 extending in the substantially radial direction, for example, the separation angle between the start point 431s and the end point 431e ( β1) may range from about 22 degrees to about 36 degrees.

In addition, a shape angle β2 from one end of the second disk second flow groove 432, for example, from the start point 432s to the end point 432e, for example, the separation angle β2 between the start point 432s and the end point 432e. ) may range from about 67 degrees to about 85 degrees.

Also, as described above, the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk may overlap at least partially in a radial direction. At this time, the angle β3 of the portion where the first flow path groove 431 of the second disk and the second flow path groove 432 of the second disk overlap, for example, the end point 431e of the first flow path groove 431 of the second disk and A separation angle β3 between the viewpoints 432s of the second disk second passage groove 432 may be in the range of about 27 degrees to about 33 degrees. It is obvious that the separation angle β3 is smaller than the shape angle β1 of the first flow path groove 431 of the second disk.

In addition, the center C of the second disk 400, the second groove portion 432-2 of the second flow path groove 432 of the second disk, and the second flow hole 412 of the second disk are an imaginary straight line. (F) can be placed on. The imaginary straight line F may be a line directed in the first direction X, but the present invention is not limited thereto.

The depth of the second flow path groove 432 of the second disk may gradually increase from the first groove part 432-1 to the second groove part 432-2. Specifically, the depth of the second flow path groove 432 of the second disk gradually increases from the start point 432s of the second disk second flow path groove 432 to the end point 432e of the second disk second flow path groove 432. can go deep More specifically, the depth of the first groove portion 432-1 and the depth of the second groove portion 432-2 may each gradually increase. The depth increase of the first groove part 432-1 and the second groove part 432-2 may be gradual, but the present invention is not limited thereto. Also, the average depth of the first groove portion 432-1 may be smaller than the average depth of the second groove portion 432-2.

In some embodiments, the shortest distance from the center C of the second disk 400 to the start point 432s may be smaller than the shortest distance from the center C to the end point 432e. As described above, this includes a first groove portion 432-1 and a second groove portion 432-2 in which the second disk second flow path groove 432 is connected to each other, but the first groove portion 432-1 and the second groove portion 432-1 are connected to each other. The extending directions of the grooves 432-2 are different, so that the second flow path groove 432 of the second disk has an approximate 'B' shape, and the second groove part 432-2 extends in a direction away from the center C. it may be because

The second disk 400 may be stacked with the first disk 300 and fixed to the case 100 so as not to rotate. That is, even when the user rotates the dial 200 to rotate the first disk 300, the second disk 400 may remain stationary on a plane without being rotated. In other words, the first disk 300 and the second disk 400 may be provided to form a relative rotational angle between them.

To this end, the second disk 400 may have a plurality of

second disk grooves

471 and 472 . For example, one 2-1 disk groove 471 is formed on the lower edge of the second disk 400, and the other 2-2 disk groove 472 is formed on the upper edge of the second disk 400. can On the inner surface of the second case 120, a locking protrusion that can engage the 2-1 disk groove 471 and/or the 2-2 disk groove 472 is formed, and the case is fitted or engaged with these protrusions. Rotation of the second disk 400 within the (100) can be prevented.

The packing 500 may be disposed below the second disk 400 . As described above, the first disk 300, the second disk 400, and the packing 500 may be sequentially stacked and disposed between the bottom surface of the second case 120 and the dial 200. The packing 500 may provide a first packing passage 511 and a second packing passage 512 . The first packing passage 511 and the second packing passage 512 may have a through hole or an opening shape. The sizes of the first packing passage 511 and the second packing passage 512 may be larger than the sizes of the first passage hole 411 of the second disk and the second passage hole 412 of the second disk.

The first packing passage 511 may be positioned substantially overlapping the first passage holes 411 of the second disk 400 of the second disk 400 and may contribute to the flow of fluid flowing into the first discharge passage portion 122a. 12 and the like illustrate a case in which one first packing passage 511 overlaps the first passage holes 411 of two second disks. In addition, the second packing passage 512 is located substantially overlapping the second passage hole 412 of the second disk 400 and can contribute to the flow of fluid flowing into the second discharge passage portion 122b. . The second packing passage 512 may be provided in two to correspond to the second passage hole 412 of the two second disks.

That is, the packing 500 is directly placed on the bottom surface of the second case 120, and the fluid trapped in the first packing passage 511 is discharged through the first discharge passage portion 122a to clean the nozzle. can be done In addition, the fluid trapped in the second packing passage 512 is discharged through the second discharge passage 122b, and the user's body can be washed through the spray nozzle.

The packing 500 is made of a material such as rubber, silicone, or synthetic resin having elasticity, and may fill a space between the lower surface of the second disk 400 and the bottom surface of the second case 120 . In addition, the packing 500 may be in close contact with the second case 120 and the second disk 400 to prevent leakage in the separation space. The packing 500 may be in a fixed state without rotating on a plane despite the rotation of the first disk 300 .

To this end, the packing 500 may include a first packing passage support part 531 , a second packing passage support part 532 , and a dummy support part 533 . The first packing passage support part 531 may have a closed curve shape surrounding the first packing passage 511 and protrude from the packing body 510 toward the upper and/or lower surfaces. The second packing passage support part 532 has a closed curve shape surrounding the second packing passage 512 and may protrude from the packing body 510 toward the upper and/or lower surfaces. Through this, it is possible to completely seal the first packing passage 511 and the second packing passage 512 in which the fluid is trapped, and the first discharge passage portion 122a and the second discharge passage portion 122b without loss of injection hydraulic pressure. through which fluid can flow.

In some embodiments, packing 500 may further include a dummy support 533 . When viewed from a plan view, the first packing passage 511 and the two second packing passages 512 may be concentrated in a partial area of the packing 500 . Accordingly, a step may be formed in another region where the first packing passage support part 531 and the second packing passage support part 532 are not disposed, and the packing 500 may not be completely adhered to the second case 120 . Accordingly, the packing 500 may further include a dummy support part 533 to level it horizontally. An inner space surrounded by the approximately closed-curved dummy support 533 may not be opened, and the packing body 510 may exist.

Hereinafter, the operation of the valve assembly 11 according to the present embodiment will be described with further reference to FIG. 14 and the like.

Fig. 14 is a plan layout showing the arrangement of the first disk and the second disk in the first state. 15 is a cross-sectional view of the valve assembly in the state of FIG. 14;

16 is a plan layout showing the arrangement of the first disk and the second disk in the second state. 17 is a cross-sectional view of the valve assembly in the state of FIG. 16;

Fig. 18 is a plan layout showing the arrangement of the first disk and the second disk in the third state. 19 is a cross-sectional view of the valve assembly in the state of FIG. 18;

Fig. 20 is a plan layout showing the arrangement of the first disk and the second disk in the fourth state. 21 is a cross-sectional view of the valve assembly in the state of FIG. 20;

Fig. 22 is a plan layout showing the arrangement of the first disk and the second disk in a fifth state. 23 is a cross-sectional view of the valve assembly in the state of FIG. 22;

In FIGS. 14 to 23 , the cross-sectional view refers to a cross-sectional view cut to show the first flow hole 311 of the first disk and the second flow hole 312 of the first disk. In addition, the case 100 and the dial 200 except for the first disk 300, the second disk 400, and the packing 500 are shown schematically in cross-sectional view so as not to obscure the essence of the present invention.

First, further referring to FIGS. 14 and 15 , an initial state, that is, a first state 11a may be a state in which the user does not operate the dial. Accordingly, from a plan view, the first flow hole 311 of the first disk 300 may be located between the first flow hole 411 of the two second disks.

In addition, the first disk first flow hole 311 and the first disk second flow hole 312 of the first disk 300 are the second disk first flow hole 411 of the second disk 400, It may not overlap with the two-disc second flow path hole 412 and the second disc second flow path groove 432 . Accordingly, the fluid flowing into the first flow hole 311 of the first disk and the second flow hole 312 of the first disk is blocked by the second disk 400, and the upper space F3 of the first disk 300 is blocked. The fluid may not flow to the bottom and may be in a blocked state. Therefore, the fluid provided from the supply passage part 121, that is, the washing water, may remain trapped in the upper space F3 of the first disk 300.

In conclusion, in the first state (11a), the first flow hole 311 of the first disk 300, the second flow hole 312 of the first disk, and the second disk of the second disk 400 The first passage hole 411, the second disk second passage hole 412, and the second disk second passage groove 432 do not contribute to fluid flow, and the first discharge passage portion 122a and the second discharge passage portion 122a All of the flow passages 122b may not discharge fluid.

Next, further referring to FIGS. 16 and 17 , the second state 11b may be a state in which the user rotates the dial 200 by a second angle θ2. The first disk 300 rotates on a plane with respect to the center C, and the relative rotation angle between the first disk 300 and the second disk 400 compared to the first state 11a, that is, the second angle ( θ2) may be formed. Specifically, in the second state 11b, the first flow hole 311 of the first disk 300 and the first flow hole 411 of the second disk 400 substantially completely overlap each other. can mean a state. As described above, the second angle θ2 may be between about 10 and 20 degrees α1.

Accordingly, the fluid introduced into the first flow hole 311 of the first disk is transferred to the first flow hole 411 of the second disk 400 and the first packing flow path 511 of the packing 500 below the second disk 400. ) can flow through. The flowed fluid may be discharged to the outside of the valve assembly 11 through the first discharge passage part 122a.

As described above, the first discharge passage portion 122a may be a passage for cleaning the spray nozzle, not for washing the user's body. Before the user rotates the dial 200 beyond the third angle as will be described later for body washing, it may be configured to automatically supply washing water for washing the spray nozzle at the level of the second angle θ2, Even when the user does not intend to clean the spray nozzle, it is possible to perform the spray nozzle without fail, so that hygiene management of the spray nozzle can be facilitated.

On the other hand, in the second state (11b), the first disk second flow hole 312 of the first disk 300 is at least partially the second disk second flow path groove 432 of the second disk 400, specifically It may overlap with the first groove part 432-1. In this case, an overlapping area between the second flow hole 312 of the first disk and the second flow groove 432 of the second disk may be 20% or more of the area of the second flow hole 312 of the first disk on a plane.

As described above, the second state 11b may be a state for substantially cleaning the spray nozzle. Although not shown in the drawing, it may be preferable to perform cleaning of the spray nozzle in an open state in order to completely clean the spray nozzle. In addition, the opening of the injection nozzle may use the pressure of the fluid discharged through the second discharge passage portion 122b.

Therefore, in the second state 11b for cleaning the spray nozzle, fluid flows through the first flow hole 411 of the second disk, and the second flow hole 312 of the first disk It overlaps with the flow path groove 432, and the fluid introduced through the second flow path hole 312 of the first disk and the second flow path groove 432 of the second disk flows through the first groove portion 432-1 and the second groove portion 432. -2) to be discharged through the second flow path hole 412 of the second disc, the spray nozzle can be opened, and the washing water discharged through the first discharge flow passage 122a in the open state of the spray nozzle. can be used to more completely clean the surface of the spray nozzle.

If the overlapping area of the first disk second passage hole 312 and the second disk second passage groove 432 is smaller than the above range, the flow rate discharged through the second discharge passage portion 122b is insufficient and the injection nozzle can be difficult to open. The upper limit of the overlapping area of the second flow path hole 312 of the first disk and the second flow path groove 432 of the second disk is not particularly limited, but may be, for example, about 50% or less. If the overlapping area is greater than the above range, a considerable amount of fluid may be injected through the second discharge passage 122b in the second state 11b, and the user's body may be washed unintentionally.

In conclusion, in the second state (11b), the first disk first flow hole 311 of the first disk 300, the second flow hole 312 of the first disk, and the second disk of the second disk 400 The first passage hole 411, the second disk second passage hole 412, and the second disk second passage groove 432 at least partially contribute to the flow of the fluid and discharge it through the second discharge passage portion 122b. A small amount of the fluid that becomes the fluid induces the opening of the injection nozzle, and the fluid discharged through the first discharge passage 122a may perform cleaning of the injection nozzle.

Next, further referring to FIGS. 18 and 19 , the third state 11c may be a state in which the user rotates the dial 200 by a third angle θ3. Specifically, in the third state (11c), the first flow hole 311 of the first disk does not overlap with the first flow hole 411 of the second disk and overlaps with the first flow groove 431 of the second disk. This may refer to a state in which the second flow path hole 312 of one disk does not overlap the second flow path hole 412 of the second disk and overlaps the second flow path groove 432 of the second disk.

In the third state (11c), the first flow hole 311 of the first disk does not overlap the first flow hole 411 of the second disk, but may be fluidly connected through the first flow groove 431 of the second disk. there is. Through this, it is possible to continuously perform cleaning of the nozzle. However, compared to the fluid cross-sectional area formed by overlapping the first flow hole 311 of the first disk and the first flow hole 411 of the second disk in the second state 11b, the first disk area in the third state 11c Since the cross-sectional area of the fluid formed by overlapping the first passage hole 311 and the first passage groove 431 of the second disk is small, the injection amount for nozzle cleaning gradually decreases, and the nozzle cleaning in a fourth state (11d) to be described later. this may end.

At the same time, in the third state (11c), the overlapping area of the second flow path hole 312 of the first disk with the second flow path groove 432 of the second disk may further increase. That is, compared to the fluid cross-sectional area formed by the first disk second passage hole 312 and the second disk second passage groove 432 in the second state 11b, the first disk second passage area in the third state 11c The cross-sectional area of the fluid formed by the passage hole 312 and the second passage groove 432 of the second disk is large, and accordingly, the amount of washing water sprayed for washing the body may increase.

Although the present invention is not limited thereto, the third angle θ3 is about 30 degrees, or about 31 degrees, or about 32 degrees, or about 33 degrees, or about 34 degrees, or about 35 degrees, or about 36 degrees, Alternatively, the fluid may flow through the first passage groove 431 of the second disk until the angle is about 37 degrees, or about 38 degrees, or about 39 degrees, or about 40 degrees.

Next, further referring to FIGS. 20 and 21 , the fourth state 11d may be a state in which the user rotates the dial 200 by a fourth angle θ4 greater than the third angle θ3. The first disk 300 further rotates with respect to the center C, resulting in a relative rotation angle between the first disk 300 and the second disk 400, that is, a fourth angle θ4 compared to the first state 11a. may be formed.

In the fourth state (11d), the first disk second flow hole 312 of the first disk 300 is the second disk second flow path groove 432 of the second disk 400, specifically the first groove ( 432-1), but the first disk first flow hole 311 of the first disk 300 is the second disk first flow hole 411 of the second disk 400, the second disk The first flow path groove 431 , the second flow path hole 412 of the second disk, and the second flow path groove 432 of the second disk may not overlap each other.

Accordingly, the fluid introduced into the first flow hole 311 of the first disk may be blocked by the second disk 400 and may not flow to the lower portion of the first disk 300 and may remain in a blocked state. On the other hand, the fluid introduced into the second flow hole 312 of the first disk flows along the second flow path groove 432 of the second disk, and the second flow hole 412 of the second disk and the packing 500 below it flow. It may flow through the second packing passage 512 . The flowed fluid may be discharged to the outside of the valve assembly 11 through the second discharge passage 122b.

As described above, in the second disk second flow path groove 432 including the first groove portion 432-1 and the second groove portion 432-2, the first groove portion 432-1 to the second groove portion ( 432-2), the width and depth may gradually increase. That is, as the angle at which the user rotates the dial 200 increases, the amount of fluid discharged through the second discharge passage 122b may increase. Accordingly, the spraying amount or spraying pressure of the washing water may be adjusted to a level desired by the user.

In conclusion, in the fourth state (11d), the first disk second flow hole 312 of the first disk 300 contributes to the flow of fluid, while the first disk first flow hole 311 contributes to the fluid flow. may not In addition, the second flow path hole 412 of the second disk 400 and the second flow path groove 432 of the second disk contribute to the flow of fluid, but the first flow hole 411 of the second disk may not contribute to the flow of In addition, the first discharge channel portion 122a does not discharge fluid, and the fluid discharged through the second discharge channel portion 122b may wash the user's body.

Next, further referring to FIGS. 22 and 23 , the fifth state 11e may be a state in which the user rotates the dial 200 by a fifth angle θ5 greater than the fourth angle θ4. The first disk 300 is further rotated about the center C, so that the relative rotation angle between the first disk 300 and the second disk 400, that is, the fifth angle θ5, compared to the first state 11a. may be formed. Specifically, in the fifth state (11e), the first disk first flow hole 311 of the first disk 300 and the second disk second flow hole 412 of the second disk 400 completely overlap each other. can mean In this state, the first disk second flow path hole 312 may overlap the second disk second flow path groove 432 . As described above, the fifth angle θ5 may be about 90 degrees.

Specifically, in the fifth state (11e), the first disk second flow hole 312 of the first disk 300 is the second disk second flow path groove 432 of the second disk 400, specifically the second It may at least partially overlap the groove portion 432-2 and/or at least partially the first groove portion 432-1. In other words, in the fifth state (11e), the second flow path groove 432 of the second disk 400 is formed by the first flow hole 311 of the first disk and the second flow hole 312 of the first disk. All can be nested.

In addition, the fluid flowing through the first disk first flow hole 311 may be discharged to the outside of the valve assembly 11 through the second discharge flow path portion 122b. In addition, the fluid introduced into the second flow hole 312 of the first disk is the second flow path groove 432 of the second disk 400 and the second flow hole 412 of the second disk and the lower part thereof. It may flow through the second packing passage 512 of the packing 500 . In addition, the fluid flowing through the second passage hole 312 of the first disk may be discharged to the outside of the valve assembly 11 through the second discharge passage part 122b. That is, the valve assembly 11 including the second disk 400 according to the present embodiment has the first flow hole 311 of the first disk and the second flow hole 312 of the first disk in the fifth state 11e. Spraying of washing water can be performed using all of them. Therefore, there is an effect that can provide a very strong water pressure.

As described above, in the fourth state 11d, only the fluid flowing through the first disk second flow hole 312 is used for washing the user's body, whereas in the fifth state 11e, the first disk first flow hole 312 ( 311) and the first disk second passage hole 312, there is an advantage in providing significantly higher washing water pressure than in the case of using any one through hole.

In conclusion, in the fifth state (11e), the first flow hole 311 of the first disk 300, the second flow hole 312 of the first disk, and the second disk of the second disk 400 The second flow path hole 412 and the second flow path groove 432 of the second disk contribute to the flow of fluid, but the first flow hole 411 of the second disk does not contribute to the flow of fluid, and the first discharge flow path portion ( 122a) does not discharge the fluid, and the fluid discharged through the second discharge passage 122b may wash the user's body.

Although not shown in the figure, when the user ends the cleaning and returns the dial 200 from the fifth state 11e (or the fourth state 11d) to the first state 11a, the above-described process is performed in reverse. It can be.
