Hereinafter, with reference to the accompanying drawings will be described in detail drain plug according to the present invention. The following embodiments are merely illustrative of the drain plug of the present invention, but are not intended to limit the scope of the invention.

As shown in Fig. 1, the drain plug 1 according to the present invention is preferably installed in a drain hole 3 formed in a sanitary appliance 2 such as a sink and a bathtub, as shown in Figs. Similarly, it consists of a structure including the stopper 10, the valve body 20, and the opening-closing control mechanism 30, and is molded and manufactured by plastic synthetic resin etc., for example.

The stopper 10 is installed in the drain hole 3 formed through the bottom surface of the sanitary appliance 2, for example, is inserted into the drain hole 3 so as to span the jaw 3a formed at the lower end of the drain hole 3. It is provided and has a structure including the valve chamber 11, the shaft hole 12, the drain hole 13, and the drain chamber 14 structurally and functionally.

The valve chamber 11 is a space formed in a cylindrical shape with a low height concave inward on the top surface of the stopper 10, and the valve plate 21 of the valve body 20, which will be described later, is rotatably inserted.

The shaft hole 12 is a hole formed in the center of the bottom surface of the valve chamber 11, and the rotation shaft 22 of the valve body 20 described later is rotatably inserted therein.

The drain holes 13 are formed through the bottom surface of the valve chamber 11 at the circumferential position of the shaft hole 12 to allow water to be drained. Preferably, the drain holes 13 are formed to face each other with the shaft hole 12 therebetween. It is not excluded that forming one, but three or more is not impossible, but not preferable.

The drainage chamber 14 is positioned below the valve chamber 11, extends downwardly from the outer periphery of the bottom of the circular valve chamber 11, so that water passing through the valve body 20 described later is discharged to the drainage pipe 4. To form a passageway through which

The drainage chamber 14 is connected to the drainage pipe 4 of the sanitary appliance 2 by, for example, screwing, fitting assembly, or the like, whereby the drain plug 1 of the present invention is provided with the drainage port 3 of the sanitary appliance 2. It acts to be connected to the drain pipe (4) in the mounted state. The drainage chamber 14 may be connected to the drainage pipe 4 via a connecting socket 60 as shown in FIGS. 2 to 5 and 7 and 8, and the drainage pipe 4 as shown in FIG. 9. You can also connect directly to). The connection socket 60 will be described later.

The valve body 20 structurally and functionally includes a valve plate 21, a rotating shaft 22, and a handle 23.

The valve plate 21 is a plate-shaped portion that is rotatably inserted into the valve chamber 11 of the stopper 10 in a state in which the surface is in contact with the valve chamber 11, and the valve plate 21 has a drain hole of the valve chamber 11 ( The drain hole 21a is formed in the position corresponding to 13).

The rotary shaft 22 extends downward from the center of the valve plate 21 to be rotatably fitted in the shaft hole 12 of the stopper 10, and the valve body 20 is attached to the stopper 10. And to be assembled in a rotatable state.

The handle 23 is formed on the upper surface of the valve plate 21, when the valve body 20 to rotate about the stopper 10, that is, to open and close the drain plug 1 of the present invention To hold by hand.

Therefore, by using the handle 23, the valve plate 21 of the valve body 20 can be rotated in the valve chamber 11 of the stopper 10, and according to the rotation state, the drain hole of the valve plate 21 When 21a and the drain hole 13 of the valve chamber 11 are matched up and down, a through hole is formed up and down, and the water can be drained (refer to B of FIG. 6). When the plate 21 blocks the drain hole 13 and the valve chamber 11 blocks the drain hole 21a, the water is not drained (see A in FIG. 6). Of course, if only a part of the drain holes 13, 21a is blocked, the drainage is made, but the amount of drainage is small.

When the rotation of the valve body 20 with respect to the stopper 10 is 360 degrees free, in order to precisely adjust the upper and lower drain holes 13 and 21a to a fully open state and a completely closed state, the user may control the drain holes 13 and 21a. There is a inconvenience to meet while looking at the bar, the opening and closing control 30 is configured to avoid such inconvenience.

The opening and closing control device 30 is composed of a rotary protrusion 31 formed on the valve body 20 side and the restriction protrusion 32 formed on the stopper 10 side.

The rotary protrusion 31 protrudes laterally from the rotary shaft 22 and rotates integrally with the rotary shaft 22. The embodiment illustrated in the drawing forms a non-circular protrusion 22a at the lower end of the rotating shaft 22, and forms an assembly hole 31a at one end of the rotary protrusion 31, thereby forming the protrusion 22a at the assembly hole 31a. By inserting the fixed pin (31b) and then fixed, the rotary projection 31 is an example configured to rotate only integrally with the rotary shaft 22, the rotary projection 31 does not rotate about the rotary shaft (22). .

The limiting projection 32 is a projection which is installed in the rotation path of the rotary projection 31 to limit the rotation of the rotary projection 31, that is, the rotary shaft 22 to a predetermined range, specific examples of FIGS. The restricting protrusion 32 is an example of protruding from the inner circumferential surface of the drainage chamber 14 toward the rotating protrusion 31, and FIG. 9 shows the restricting protrusion 32 protruding from the bottom of the valve chamber 11 toward the rotating protrusion 31. The formed towing bar, the bending of the rotary projection 31 in the latter is for shortening the length of the limiting projection (32).

Preferably, the restricting protrusion 32 restricts the rotation of the rotary protrusion 31 in an open position where the drain hole 13 of the stopper 10 and the drain hole 21a of the valve body 20 are completely coincident with each other. Rotation protrusion 31 in the position which restricts rotation of 20 (B of FIG. 6), and the closed position in which the drain hole 13 of the plug 10 and the drain hole 21a of the valve body 20 are completely interlaced. It is formed in two of the positions (A of FIG. 6) which restrict rotation of the valve body 20 by restrict | limiting rotation of the.

When each of the two drain holes 13 and 21a is formed, it is preferable that the respective drain holes 13 and 21a are disposed at positions facing each other with respect to the shaft hole 12 and the rotating shaft 22, in which case the limiting protrusion 32 is formed at a position approximately 90 degrees away from the rotation axis 22.

Although the drain port stopper 1 of the present invention can be fixed to the drain port 3 by simply inserting the plug 10 tightly into the drain port 3 while the stopper 10 is locked to the jaw 3a, the stopper 10 Is inserted into the drain port 3 so that the drain chamber 14 protrudes through the drain port 3, and then tightens the fixing screw 40 to the outer periphery of the drain chamber 14 from below, thereby draining the drain port plug of the present invention. It is preferable to make (1) more firmly fixate to the sanitary appliance 2. At this time, the fixing nut 40 may be formed into a hexagonal or octagonal outline of the outer circumference so as to be fastened by a tool or hand.

The drainage chamber 14 protruding downwardly from the fixing nut 40 can be tightly assembled by screwing or fitting the drain pipe 4 of the sanitary appliance 2 with or without a connecting socket 60. Can be.

When the rotating shaft 22 of the valve body 20 is just fitted in the shaft hole 12 of the stopper 10, the close contact between the valve chamber 11 and the valve plate 21 is insufficient. There may be an unintended leak in the gap between them. This leakage can be significantly prevented by manufacturing the material of the stopper 10 and the valve body 20 using a synthetic resin having excellent adhesion, and even if the leakage is very small, but to prevent such leakage more reliably You can add a configuration.

In the illustrated embodiment, the valve chamber 11 and the valve plate 21 are inserted by inserting an elastic member 50 such as a spring into the rotation shaft 22 to press the valve body 20 against the stopper 10. ) Is an example of preventing leakage by making the contact more closely.

During the use of the drain plug 1 according to the present invention, there is a case where a problem occurs in the operation due to the clogging of foreign substances such as hair, and the like (eg, cleaning, repair, etc.) may be necessary. At this time, when the sanitary appliance 2 to which the stopper 1 of the present invention is applied is the wash basin 2 as shown in FIG. 1, the drain pipe 4 or the connecting socket 60 is removed and the fixing nut 40 is released. (1) can be pulled out above the drain 3 and there is no problem in the inspection, but when the sanitary appliance 2 to which the present invention is applied is, for example, a bath 2 fixedly installed in a bathroom (see Fig. 9), Since it is practically difficult to separate the drain pipe 4 or the connecting socket 60 from below unless it is removed, it is possible to check the inside of the drain plug 1 of the present invention while maintaining the installation state of the bathtub. It may be desirable.

To this end, unlike the embodiment of FIGS. 2 and 8 in which the drainage chamber 14 and the valve chamber 11 of the plug 10 are integrally formed, as shown in FIG. 9, the drainage chamber 14 And the valve chamber 11 are formed separately so that the valve chamber 11 can be separated and assembled from the drain chamber 14 as necessary.

In the embodiment shown in Fig. 9, an assembly pipe 14a is formed on the upper side of the drain chamber 14 formed of a member separate from the valve chamber 11, the size of which corresponds to the outer contour of the valve chamber 11. The valve chamber 11 is an example in which the screw formed on the outer circumferential surface thereof is detachably assembled by screwing the screw formed on the inner circumferential surface of the assembly pipe 14a.

Therefore, when the valve chamber 11 is separated from the drainage chamber 14, the whole of the stopper 10 except for the drainage chamber 14, the whole of the valve body 20, and the opening / closing control opening 30 are separated. You can check it.

As mentioned above, the drainage chamber 14 of the plug 10 may be directly connected to the drainage pipe 4, but may be connected to the drainage pipe 4 via the connection socket 60.

The connecting socket 60 applied to the present invention is a socket through which water passes through the drainage chamber 14 and the drainage pipe 4, and includes a stopper connector 62 and a drainage pipe connector 63.

The plug connector 62 extends upward from the outer circumference of the bottom surface 61 of the connecting socket 60 and is screwed to the outer circumference of the drainage chamber 14 to connect the connecting socket 60 to the stopper 10. The drain pipe connector 63 is formed to protrude downward from the bottom surface 61 of the connection socket 60 to connect the connection socket 60 to the drain pipe 4, and by using such a connection socket 60 In the construction of the plug 1 of the invention can be more easily connected to the drain pipe (4).

In general, a sanitary appliance related to drainage is provided with a trap for preventing backflow of odor. For example, the sanitary device (2: wash basin) of FIG. 1 is provided with a trap T in which a part of the drain pipe 4 is bent in an S shape or a P shape, and a certain amount of water is provided in the S shape (or P shape). This standing up blocks the backflow of odor.

As such, a sanitary appliance (2) such as a sink or a bath to which the drain plug stopper (1) of the present invention can be applied needs a trap for preventing malodorous backflow, and the drain plug (1) of the present invention has an extended drainage chamber ( 14) or by adding a trap structure to the connection socket 60, it is possible to avoid the need to install a separate trap in the drain pipe (4) for blocking bad smell backflow.

In the drain plug 1 of the present invention illustrated in Figs. 7 and 8, a trap structure is added to the connecting socket 60. In addition to the plug connector 62 and the drain pipe connector 63, the connection socket 60 applied to this embodiment further includes a protrusion drain 64, a reservoir 65, and a trap cap 66.

The protruding drain 64 is a hole formed in the bottom surface 61 of the connecting socket 60 so that water can be drained, and preferably protrudes upward from the center of the bottom surface 61.

The reservoir 65 is partitioned by a stopper connector 62, a bottom 61, and a protruding drain 64 to temporarily open water in which water is temporarily stored.

The trap cap 66 is a cap-shaped member having an open bottom, which is mounted on the protruding drain 64, and the lower end 66a is immersed in the water of the reservoir 65 to move the reservoir 65 from the bottom to the outside. By allowing water to pass through, the drainage of the drainage chamber 14 is allowed to drain to the drainage pipe 4 via the reservoir 65, but the odor flows from the drainage pipe 4 back to the drainage chamber 14 to be blocked. A plurality of legs 66b may be formed at the lower end 66a of the trap cap 66 so that the trap cap 66 may be supported on the bottom surface 61.

According to the structure of the connection socket 60 as described above, the water introduced through the drain holes 13 and 21a flows into the drainage chamber 14 and is temporarily stored in the reservoir 65, and the drainage chamber is continued by the inflow of water. If the water level of 14) is higher than the height of the protruding drain 64, the overflowed water is drained through the protruding drain 64 to the drain pipe 4, but the odor from the drain pipe 4 is filled in the reservoir 65. And blocked by the trap formed by the lower end of the trap cap 66 is prevented backflow through the drain chamber 14 and the drain holes (13, 21a).

In the case of the embodiment of FIG. 9 without applying the connection socket 60, although not shown, the trap structure may be formed in the drainage chamber 14. That is, the bottom surface corresponding to the bottom surface 61 of the connection socket 60 described above is formed in the drainage chamber 14, and in addition, the drain pipe connector 63, the protruding drain port 64, the water storage part 65 and the trap cap ( If the configuration corresponding to 66) is formed in the drainage chamber 14, a trap structure can be integrated in the drain plug 1 of the present invention without applying the connecting socket 60.

In FIG. 8, reference numeral 5 denotes a bypass for guiding more than a predetermined amount of water from the sink 2 to the drain pipe 4, and if such a bypass 5 is present, the drainage chamber 14 drains from the bypass 5. The side hole 14b which flows into the chamber 14 is formed.
