  FIG. 1 is a plan view showing the operation of a water valve to which a water valve cartridge having a left-right click type step operating means according to an embodiment of the present invention is applied, and FIG. 2 is related to one embodiment of the present invention. FIG. 3 is a perspective view showing a water supply valve cartridge having left and right click type step operation means, FIG. 3 is a front exploded perspective view of FIG. 2, FIG. 4 is a rear exploded perspective view of FIG. 2, and FIG. FIG. 6 is a combined perspective view of FIG. 5 and FIG. 7 is a cross-sectional perspective view of a left-right click type step operation means region.

  Referring to these drawings, a water supply valve cartridge according to an embodiment of the present invention is mounted on a faucet 1 as shown in FIG. 1, and is a modular type that takes charge of a cold water and hot water discharge function, a flow rate adjustment function, and the like. FIG. 1 shows a housing 80 that is an external part of the lever 10 coupled to the handle 2 of the faucet 1 and a plurality of built-in parts (not shown) for discharging cold water, hot water or mixed water. As shown in the figure, when the handle 2 is rotated left and right, the left and right click type step operation means 90 (in which the chilled water section and the mixed water section can be distinguished by allowing the handle to move stepwise while being clicked) FIG. 7).

  As shown in FIGS. 3 and 4, the plurality of built-in parts are parts for discharging cold water, hot water or mixed water, and include a fixed disk 20, a movable disk 30, a disk cover 40, a sliding guide 50, and a seat 70. Which are coupled to the housing 80 at respective positions.

  The water supply valve cartridge of the present embodiment selects cold water and hot water flowing in through the body of the faucet 1 shown in FIG. (Not shown).

  In particular, as shown in FIG. 2, the water valve cartridge according to the present embodiment lifts the lever 10 in the off state located at the center, specifically, the handle 2 coupled to the lever 10 or the like. When it is lowered, cold water is discharged, the handle 2 is rotated to the left, and after the lever 10 is clicked, the mixed water is discharged. That is, the water supply valve cartridge of the present embodiment is mixed when the lever 10 located at the center, specifically, when the handle 2 coupled to the lever 10 is rotated to the left, the handle is clicked. It presents a structure that informs you that it has become a water section.

  In this way, the lever 10 can be turned on in multiple stages, for example, in the first stage section and the second stage section, and in this case, each stage can be operated as a cold water section and a mixed water section as in this embodiment. When applied separately, since only cold water is discharged in the cold water section, an energy saving effect can be expected. In particular, since the lever 10 is located only in the cold water section before the lever 10 is clicked, the use probability of the mixed water is reduced. As a result, the use of the mixed water is prevented and the energy saving effect can be improved.

  Hereinafter, each structure of the water supply valve cartridge which concerns on a present Example is demonstrated.

  First, the lever 10 is coupled to the handle 2 of the faucet 1 shown in FIG. 1, and when the user operates the handle 2, the lever 10 is operated in the same direction as the handle 2.

  Such a lever 10 is an element that pulls the rotation of the movable disk 30 for discharging cold water, hot water, or mixed water. The upper step portion of the lever 10 is exposed to the outside of the housing 80, and the lower step portion is disposed inside the sliding guide 50 and connected to the sliding guide 50.

  The fixed disk 20 is a component that is fixed at a corresponding assembly position. Although not shown, the fixed disk 20 is provided with a cold water inlet through which cold water flows, a hot water inlet through which hot water flows, and a mixed water outlet through which mixed water is discharged.

  For reference, since cold water or hot water may be discharged from the mixed water discharge port in addition to the mixed water, it is preferable to name it as a water discharge port, but for the smooth flow of the description, the mixed water discharge port Shall be named.

  A sheet 70 is coupled to the lower part of the fixed disk 20. The seat 70 is connected to the housing 80. The sheet 70 is provided with a plurality of through holes H through which cold water, hot water, and mixed water enter and exit. An inner packing and a bottom O-ring are fitted on the upper and lower sides of the through hole H, respectively, but the illustration is omitted.

  Unlike the fixed disk 20, the movable disk 30 is a component that is coupled to the fixed disk 20 so as to be relatively movable.

  The movable disk 30 selectively opens and closes the cold water inlet, the hot water inlet or the mixed water outlet while operating together with the operation of the lever 10. Therefore, the movable disk 30 is provided with a through hole (not shown), and cold water or mixed water can be discharged depending on the degree of relative arrangement between the through hole and the cold water inlet or the hot water inlet.

  The disk cover 40 is a component that is coupled to the movable disk 30. The disk cover 40 is coupled to the movable disk 30 at the lower part and is coupled to the lever 10 at the upper part to transmit the rotational force of the lever 10 to the movable disk 30.

  The sliding guide 50 is connected to the lever 10 and serves to guide the sliding operation of the lever 10. The sliding guide 50 is connected to the disc cover 40 on one side.

  As shown in FIGS. 5 and 6, the sliding guide 50 is provided with an insertion groove 51 into which the step operation member 92 of the left and right click type step operation means 90 is inserted and coupled.

  The insertion groove portion 51 communicates with the trunk portion insertion groove portion 51a into which the trunk portion 92a of the step operation member 92 is inserted, and the projection into which the plurality of rotation prevention projections 92d of the step manipulation member 92 are inserted. And an insertion groove 51b. One protrusion insertion groove 51b is provided at a position symmetrical to each other on both sides of the body insertion groove 51a.

  The housing 80 forms the appearance of the fixed disk 20, the movable disk 30, the disk cover 40 and the sliding guide 50 together with the sheet 70.

  In this embodiment, the housing 80 includes a housing body 81 and a housing neck 82 that is connected to the housing body 81 and has a smaller diameter than the housing body 81.

  On the other hand, when the handle 2 (see FIG. 1) is rotated to the left or right, the left-right click type step operating means 90 allows the handle to move stepwise while being clicked, and the cold water section and the mixed water section are distinguished. So that

  In other words, the left-right click type step operating means 90 is arranged in the cold water section while the handle 10 is clicked when the lever 10 arranged at the center, specifically, the handle 2 coupled to the lever 10 is rotated left or right. And mixed water areas should be recognized separately.

  In FIG. 1, the cold water section and the mixed water section are formed with the same area as each other. However, if necessary, the cold water section or the mixed water section is adjusted to be formed with a wider area. May be.

  The left and right click type step operation means 90 having such a role includes a click means 91 and a step operation member 92 located in the cold water section or the mixed water section while going back and forth beyond the click means 91.

  The housing neck 82 is preferably formed with an elastic incision portion 83 that is partially incised and retains elasticity, and the click means 91 of the left-right click type step operation means 90 protrudes from the inner wall of the elastic incision portion 83. . In the illustrated embodiment, the click means 91 is integrally formed with the housing neck 82, but the step operating member 92 is a structure manufactured separately, and is coupled while being inserted into the insertion groove 51 of the sliding guide 50. Is done. Of course, the click means 91 may also be coupled to the housing neck 82 as a separate body. Further, the case where the click means 91 protrudes from the inner wall of the housing neck 82 without the elastic incision portion 83 is not excluded from the scope of the right of the present invention. However, the click sensitivity is better when the elastic incision portion 83 is provided. And it will be more preferable in increasing click sound.

  The inner wall of the housing neck 82 is provided with a first depressed section 91a and a second depressed section 91b that form a cold water section and a mixed water section with a click means 91 interposed therebetween. As shown in FIG. 2, the step operating member 92 is positioned in the first depressed section 91a with the lever 10 positioned at the center. In the present embodiment, the step operated member 92 is thus in the first depressed section 91a. It is set as the cold water area where cold water is discharged when it is located.

  On the other hand, the step operation member 92 is a structure located in the cold water section or the mixed water section beyond the click means 91.

  Such a step operation member 92 is provided through the body 92a inserted into the body insertion groove 51a of the sliding guide 50 and the plate surface of the body 92a, and resonates the sound when clicked to generate the click sound. It has a cavity 92c to be increased, and a protrusion contact portion 92b that is formed at the exposed end of the trunk portion 92a and is in contact with the click means 91 and beyond the click means 91 and located in the cold water section or the mixed water section.

  Unlike the conventional technology, the body 92a is provided with the cavity 92c, so that the click sound can resonate in the cavity 92c at the time of click, so that the click sound is significantly increased. The distinctive recognition effect of the hot water section can be greatly improved.

  The outer surface of the protrusion contact portion 92b is processed into an arc so that the protrusion contact portion 92b can come in contact with the click means 91 and smoothly go over the click means 91. Of course, the scope of the right of the present invention is not necessarily limited to the arc shape, and may be a triangle shape.

  The body 92a is further provided with a plurality of anti-rotation protrusions 92d protruding in opposite directions from both side surfaces. The plurality of anti-rotation protrusions 92d are clicked by being inserted into the protrusion insertion groove 51b. Sometimes the rotation of the body 92a can be prevented.

  The operation of the water valve cartridge having such a configuration will be described.

  As shown in FIG. 2, the lever 10, that is, the handle 2 coupled to the lever 10 is rotated to the left while the lever 10 is located at the center and is utilized as a cold water section. Then, the step operation member 92 is positioned in the second depression section 91b beyond the click means 91. This state is a mixed water section in which mixed water is discharged.

  When the mixed water section starts, a click operation in which the step operation member 92 passes through the click means 91 is performed, so that the click sensitivity is improved, and in particular, the click sound is remarkably increased by the cavity 92c. For this reason, it can make a user fully recognize that it became the mixed water area.

  Therefore, according to the present embodiment, when the user rotates the faucet handle 2 coupled to the lever 10 from the right side to the left side, the step operation member 92 moves along the first depressed section 91a, and only cold water is used. However, if it is clicked by the click means 91, it enters the second depression section 91b and the mixed water is discharged.

  According to this embodiment having such a structure and operation, the cold water section and the mixed water section are separated by allowing the handle 2 to move stepwise while the handle 2 is rotated left and right. It can be easily recognized that it is formed, the click sensitivity at the time of step operation can be improved, and the click sound can also be increased remarkably.

  Thus, the present invention is not limited to the described embodiments, and various modifications and variations can be made without departing from the spirit and scope of the present invention. It is clear to those who have knowledge of. Therefore, those modifications or variations can be construed as being included in the scope of the claims of the present invention.
