may have a structure attached to a wall or erected in the form of a stand. The washbasin
is made of sanitary ware and is installed on the wall of a bathroom or toilet. A pop-up
valve is mounted on the drain of the washbasin so as to block the drain of the washbasin
to trap water or to open the drain to let the water out of the washbasin. The pop-up
valve opens and closes a drain pipe through a pop-up operation. The pop-up operation
of the pop-up valve is automatically performed by an elastic member such as a spring
mounted inside the valve. A guide device for inducing the pop-up operation of the
pop-up valve is provided inside the drain pipe for stable lifting of the pop-up valve.
The guide device includes a guide vane that is radially formed. A pop-up rod of the
pop-up valve moves performs a lifting operation in a state of being coupled to a coupling
hole of the guide device.
[0003] However, the pop-up valve of related art is not provided with a foreign matter catching
prevention device, and thus, foreign matters such as hair are caught on a guide vane
of the guide device to cause the drain pipe to be frequently blocked.

[0020] Hereinafter, a preferred embodiment of the present invention will be described in
detail with reference to the accompanying drawings. First of all, in adding reference
numerals to the configuration elements of each drawing, it should be noted that the
same configuration elements have the same reference numerals as much as possible even
if illustrated in different drawings. Further, the following will describe the preferred
embodiment of the present invention, but the technical idea of the present invention
is not limited thereto and may be changed to be variously implemented by those skilled
in the art.
[0021] First, a configuration of a pop-up valve according to an embodiment of the present
invention will be described.
[0022] As illustrated in FIGS. 1 to 3, the pop-up valve according to the embodiment of the
present invention includes a head portion 10 for opening and closing a drain of a
washbasin and a foreign matter catching prevention device 20 provided in a lower portion
of the head portion 10.
[0023] The foreign matter catching prevention device 20 is coupled to the lower portion
of the head portion 10. The foreign matter catching prevention device 20 includes
a body portion 21, a protruding jaw 22 formed radially along an outer circumference
of the body portion 21, and a first guide vane 23 extending downward from a bottom
of the protruding jaw 22.
[0024] Specifically, the body portion 21 is coupled to a bottom of the head portion 10.
The body portion 21 may have a shape of a cylinder. The center of the body portion
21 may be provided with a hole through which an upper portion of the pop-up rod 30
passes.
[0025] The protruding jaw 22 is formed radially on an outer circumference of the body portion
21. FIGS. 1 to 3 illustrate three protruding jaws 22, but the protruding jaws are
not limited to this and may be three or more. For example, if there is a gap between
the head portion 10 and the protruding jaw 22, a foreign matters such as hair may
enter the gap, and thus, an upper surface of the protruding jaw 22 has to be designed
to be in close contact with a bottom of the head portion 10 without being spaced apart
from the head portion 10.
[0026] The first guide vane 23 extends downward from the bottom of the protruding jaw 22
so as to be perpendicular to the protruding jaw 22. The protruding jaw 22 has to be
designed to be greater than a thickness of the first guide vane 23 so as to cover
the first guide vane 23. The first guide vane 23 is located on one side of a second
guide vane 43 of a guide device 40 coupled to an inside of the drain pipe 50.
[0027] The guide device 40 is a device that induces stable lifting operations of the foreign
matter catching prevention device 20 and the pop-up rod 30. The guide device 40 includes
a guide main body 42 and the second guide vane 43.
[0028] Specifically, the guide main body 42 is located inside the drain pipe 50. A lower
portion 422 of the guide main body 42 may be a cone whose vertex faces downward. A
coupling hole 421 is provided inside the guide main body 42. The coupling hole 421
is formed in the center of the guide body 42. A lower end portion of the pop-up rod
30 is coupled to the coupling hole 421. The coupling hole 421 induces a stable lifting
operation of the pop-up rod 30.
[0029] The second guide vane 43 is formed radially along an outer circumference of the guide
body 42. Since the second guide vane 43 is formed in a radial shape, a compartment
space 44 is formed between the second guide vane 43 and the second guide vane 43.
A lower end 431 of the second guide vane 43 is located at a lower portion in the drain
pipe 50. A catching jaw 51 to which the lower end 431 of the second guide vane 43
is correspondingly hooked to be coupled may be provided at a lower portion of an inner
circumferential surface of the drain pipe 50.
[0030] The foreign matter catching prevention device 20 is connected to the guide device
40 by the pop-up rod 30. Specifically, an upper portion of the pop-up rod 30 is connected
to the head portion 10 through the foreign matter catching prevention device 20. A
lower portion of the pop-up rod 30 is inserted into the coupling hole 421 of the guide
main body 42.
[0031] FIGS. 1 to 3 illustrate three second guide vanes 43, the present invention is not
limited thereto, and the second guide vanes 43 may be configured by three or more
guide vanes. The second guide vanes 43 have to be designed in the same number as the
first guide vanes 23.
[0032] The first guide vanes 23 and the second guide vanes 43 are configured by at least
three or more guide vanes. Two of three or more first guide vanes 23 perform a lifting
operation in a state of being located in the same compartment space 44 and in a state
of being touched to one side of the second guide vane 43.
[0033] As illustrated in FIGS. 4 and 5, the head portion 10 serves to open and close a drain
of a washbasin and includes a main body portion 11 and a sealing member 12 coupled
to a lower portion of the main body portion 11. The main body portion 11 is formed
in a shape fitting with the drain of the washbasin. The main body portion 11 may be
formed of metal. The sealing member 12 may be a rubber packing for maintaining airtightness.
[0034] An upper portion of the pop-up rod 30 is connected to the bottom of the head portion
10 passing through the center of the body portion 21 of the foreign matter catching
prevention device 20. The upper portion of the pop-up rod 30 may be screwed to the
head portion 10. The pop-up rod 30 is a device that lifts the head portion 10 by mounting
an elastic member such as a spring therein. The pop-up rod 30 is a known technology
and detailed description on a configuration will be omitted.
[0035] The following describes an operation of a pop-up valve according to the embodiment
of the present invention.
[0036] The pop-up valve according to the embodiment of the present invention illustrated
in FIG. 6 is coupled to the drain pipe 50 connected to the drain of the washbasin.
[0037] As illustrated in FIG. 7, the guide main body 42 of the guide device 40 is coupled
to an inside of the drain pipe 50. The first guide vane 23 of the foreign matter catching
prevention device 20 performs a lifting operation in a state of being touched to or
being in contact with one side of the second guide vane 43 of the guide device 40
at a minute interval.
[0038] Since each of two of the three or more first guide vanes 23 performs a lifting operation
along one side of the second guide vanes 43 in a state of being located in the same
compartment space 44, stable lifting of the first guide vane 23 is possible. Specifically,
since the first guide vane 23 performs the lifting operation in a state in which the
first guide vane 23 touches the second guide vane 43, the first guide vane 23 can
perform the lifting operation without being twisted.
[0039] Since the second guide vane 43 serves to guide the lifting operation of the first
guide vane 23, the first guide vane 23 can perform a stable lifting operation without
departing from a movement line without a separate guide device.
[0040] Further, since the first guide vane 23 is located to overlap one side of the second
guide vane 43, foreign matters such as hair discharged to the drain pipe 50 together
with water through a washbasin drainage flows down naturally along the first guide
vane 23 and the second guide vane 43, and thus, there is no fear of the foreign matter
blocking the drain pipe 50. In addition, since the first guide vane 23 moves while
performing the lifting operation, foreign matters such as hair can be discharged more
smoothly along the drain pipe 50.
[0041] Further, since water discharged to the drain pipe 50 flows to the center of the drain
pipe 50 along the lower portion 422 of the conical guide main body 42, the drainage
can be made more smoothly.
[0042] Further, in the pop-up valve according to the embodiment of the present invention,
the head portion 10 and the foreign matter catching prevention device 20 can be easily
disassembled and assembled through the pop-up rod 30. Further, since there is no gap
between the head portion 10 and the protruding jaw 22 because an upper surface of
the protruding jaw 22 of the foreign matter catching prevention device 20 is in close
contact with the sealing member 12 of the head portion 10, there is no fear of foreign
matters being caught.
[0043] As described above, in a pop-up valve according to the embodiment of the present
invention, a first guide vane of a foreign matter catching prevention device is located
on one side of a second guide vane of a guide device, and thereby, foreign matters
such as hair discharged together with water to a drain pipe can flow down naturally
along the first guide vane and the second guide vane without being caught by the second
guide vane. Further, since the first guide vane performs a lifting operation in a
state of being touched to the second guide vane, the first guide vane can perform
a stable lifting operation without departing from a movement line.
[0044] The above description is merely illustrative of the technical idea of the present
invention, and various modifications, changes, and substitutions may be made by those
skilled in the art without departing from the essential characteristics of the present
invention. Accordingly, the embodiments and the accompanying drawings disclosed in
