Definitions

  • the present invention relates to a washbasin pop-up valve for opening and closing a drain hole of a washbasin.
  • a washbasin is a container that can hold water to wash the face, hands, etc. of a user.
  • the washbasin may be attached to a wall or formed in a stand type structure.
  • the washbasin is made of sanitary ware (or pottery) and is installed on the wall of a bathroom or toilet.
  • the washbasin has a drain hole and a pop-up valve fitted in the drain hole to open and close the drain hole in order to drain off and/or store water in the washbasin.
  • the pop-up valve serves to open and close the drain hole.
  • the pop-up valve is coupled to an operating lever. The drain hole is opened when a head part of the pop-up valve is lifted up by operation of the operating lever.
  • pressing a stem connected to the operating lever may rotate the operating lever about a hinge axis and push up the pop-up valve, thereby lifting up the head part and opening the drain hole.
  • the operating lever connected to the pop-up valve returns to an original position thereof and the drain hole is closed by the head part.
  • the existing pop-up valve does not include any alternative device to enclose the operating lever part located inside the drain hole and thus causes clogging of the drain hole due to foreign substances such as hair stuck in the lever part exposed within the drain hole.
  • Korean Utility Model Registration No. 20-0400063 discloses a "Drain valve for washstand".
  • an embodiment of the present invention provides a washbasin pop-up valve wherein an operating lever part exposed within a drain hole is enclosed by a foreign substance clogging prevention cover, thereby preventing foreign substances (debris) discharged through the drain hole from sticking to the operating lever.
  • the washbasin pop-up valve may further include: a head part for opening/closing the drain hole; and a debris clogging prevention cover which extends downward from the bottom of the head part and has a width corresponding to the drain hole wherein a cover member is disposed on a lower portion of the debris clogging prevention cover in order to enclose an operating lever, wherein the cover member is divided into two branches above the operating lever while enclosing a lever portion of the operating lever exposed within the drain hole, and the cover member includes a first cover and a second cover facing the first cover, wherein there is a space present between the first cover and the second cover, a first support is provided inside the first cover and a second support is provided inside the second cover to correspond to the first support, wherein the first support has a first hole surrounding half of the operating lever while the second support has a second hole surrounding the other half of the operating lever, which is opposed to the first hole.
  • connection portion between an upper portion of the debris clogging prevention cover and the cover member may be formed to have a curved face along which water smoothly flows down.
  • blades close to the inner wall surface of the drain hole which form a '+' shape together with the debris clogging prevention cover, may be provided at opposite lateral faces of the debris clogging prevention cover.
  • the lever portion exposed within the drain hole is enclosed by the debris clogging prevention cover, so as to fundamentally prevent the debris, which was discharged through the drain hole, from sticking to the operating lever.
  • the washbasin pop-up valve may include a head part 20, a debris clogging prevention cover 30 disposed on the bottom of the head part 20, blades 30 to form a '+' shape together with the debris clogging prevention cover 30.
  • the head part 20 may serve to open and close a drain hole 51 of the washbasin.
  • the head part 20 may have a circular form corresponding to the drain hole 51 in order to plug up the drain hole 51.
  • a typical elastic packing for closing the drain hole 51 may be coupled to a lateral face of the head part 20.
  • the debris clogging prevention cover 30 may be formed with a width corresponding to the drain hole.
  • the debris clogging prevention cover 30 may extend downward from the bottom 21 of the head part 20.
  • the debris clogging prevention cover 30 may act to prevent debris from sticking to the operating lever 40.
  • the debris clogging prevention cover 30 may be connected to an operating lever 40.
  • the debris clogging prevention cover 30 may include a cover member 300 provided on a lower portion thereof to enclose the operating lever 40.
  • the cover member 300 may be divided into two branches above the operating lever 40 while enclosing a lever portion of the operating lever 40 exposed within the drain hole 51 of the washbasin 50.
  • the cover member 300 may include a first cover 310 and a second cover 320 facing the first cover 310. There is a space 340 between the first cover 310 and the second cover 320, which is required to operate the operating lever 40.
  • the first cover 310 and the second cover 320 may enclose the operating lever 40 in order to prevent debris such as hair from sticking to the operating lever 40.
  • a first support 311 may be provided inside the first cover 310. Further, a second support 321 facing the first support 311 may be provided inside the second cover 320.
  • the first support 311 may have a first hole 312 surrounding half of the operating lever 40.
  • the first hole 312 may have a semicircular shape.
  • the second support 321 may have a second hole 322 surrounding the other half of the operating lever 40, which is opposed to the first hole 312.
  • the second hole 322 may also have a semicircular shape.
  • the first hole 312 and the second hole 322 meet to form a single circle.
  • a connection face between an upper portion of the debris clogging prevention cover 30 and a lower portion of the same, that is, the cover member 300, is designed as a curved face 330 along which water or debris smoothly flows down.
  • Blades 60 may be provided at front and rear sides of the debris clogging prevention cover 30.
  • the debris clogging prevention cover 30 may be welded to the head part 20 or integrally coupled to the head part 20.
  • the blades 60 may be provided at both of the front side and the rear side of the debris clogging prevention cover 30.
  • the blades 60 may form a '+' shape together with the debris clogging prevention cover 30.
  • the blades 60 should be designed to be close to an inner wall surface of the drain hole 51 of the washbasin 50.
  • the blades 60 may serve as a guide to ensure smooth flow of the water through the drain hole 51 and, at the same time, as a rib to reinforce durability of the debris clogging prevention cover 30.
  • a shape of the blade 60 may be altered. More particularly, a lower portion of the blade 60 may be located below the debris clogging prevention cover 30, so as to reinforce rigidity of the debris clogging prevention cover 30.
  • the operating lever 40 rotates about a hinge axis 70 and pushes up the pop-up valve by operation of the stem. While the pop-up valve is lifted up, the head part 20 plugging up the drain hole 51 escapes from the drain hole 51, thereby opening the drain hole 51.
  • the drain hole 51 When the drain hole 51 is opened, water and debris such as hair may be discharged through the drain hole 51.
  • the lever portion (of the operating lever 40) exposed within the drain hole 51 is substantially shielded by the first cover 311 and the second cover 312, therefore, the debris flowing through the drain hole 51 does not stick to the exposed portion of the operating lever 40 inside the drain hole 51 but can be directly drained through the drain hole 51. More particularly, the debris smoothly flows along the outer surfaces of the first cover 311 and the second cover 312 and is discharged through the drain hole 51.
  • the operating lever 315 may return to an original position thereof while the drain hole 51 is plugged up by the head part 20.
  • the conventional operating lever 40 is coupled to the debris clogging prevention cover by correctly fitting the operating lever 40 into a hole, and this coupling process is not easily conducted.
  • the operating lever 40 can be easily and simply coupled to the debris clogging prevention cover by pushing the same between the first cover 310 and the second cover 320.
  • the first cover 310 and the second cover 320 are naturally widened. More specifically, when pushing the operating lever 315 between the first cover 310 and the second cover 320, a narrow spacing between the first support 311 and the second support 321 is widened so that the operating lever 315 can enter the same and be disposed in the first hole 312 and the second hole 322 via the widened spacing. As soon as the operating lever 315 is located in the first hole 312 and the second hole 322, the first support 311 and the second support 321 are narrowed again to complete coupling of the operating lever 315.
  • the washbasin pop-up valve according to the embodiments of the present invention may enclose a lever portion of the operating lever exposed within a drain hole by a debris clogging prevention cover, so as to fundamentally prevent debris, which is discharged through the drain hole, from sticking to the operating lever. Further, unlike the conventional coupling mode of the operating lever by correctly fitting the operating lever into a hole, the operating lever according to the present invention can be easily and simply coupled by pushing the operating lever into a first hole and a second hole.
