Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-touch pop-up type opening / closing device for a drainage hole,

More particularly, the present invention relates to a one-touch pop-up type drainage opening and closing apparatus, and more particularly, to a drainage opening and closing apparatus for a one-touch pop-up type drainage opening, And more particularly, to a one-touch pop-up type drainage opening / closing apparatus in which an accessory device such as an opening / closing valve is not lost.

Generally, a drain port is connected to a sink or a bathtub, and a lever type opening and closing device and a pop-up type opening and closing device are mainly used as the opening and closing device for controlling the opening and closing of the drainage port.

The lever type switchgear is a method in which the drainage cover connected to the lever is vertically moved by opening and closing the drainage port by operating a lever installed at a certain point such as a washstand in a vertical direction, and a link for connecting the lever and the cover The use of the drainage hole is becoming less and more frequent due to the problem that the opening and closing of the drainage hole is loosened, the fault is frequent and the repair is difficult in case of failure.

On the other hand, the pop-up type switchgear is installed between the drainage port of the washstand and the drainage pipe, so that the drainage port is opened once when the drainage port cover constituting the opening and closing device is opened and the drainage port is sealed once again, Recently, usage is increasing.

1 shows a general configuration of a pop-up type switching device according to the prior art.

As shown in FIG. 1, the conventional pop-up type switching device includes a connection pipe 30 provided between a drain port and a drain pipe, an open / close valve 20 fixed inside the connection pipe and configured to move up and down by pressure, And a cover 10 connected to an upper portion of the valve to open or close the drain port in accordance with the upward / downward movement of the open / close valve. The open / close valve 20 includes a fixing portion 26 fixed to the inside of the connection pipe, (Not shown) interposed between the fixing part and the operating part when the operating part is pressed, and an operating part 22 which is inserted into the fixed part and repeatedly reciprocates up and down by pressurization. The operation unit is elastically moved upward and downward within the fixed unit, and is opened and closed by opening and closing the upper portion of the connection pipe 30 through the lid 10 connected to the upper portion of the operation unit.

In order to install the opening / closing valve and the lid connected to the pop-up type opening / closing device in the drain port, the opening / closing valve must be fixed inside the connection pipe. For this purpose, And a support portion formed of a pair of support bars 36 extending along the inner wall and an annular support 37 provided therebetween. In addition, a thread is formed on the inner circumferential surface of the annular support, and the opening / closing valve is fixed to the support portion by screwing with the male screw 28 at the lower end of the opening / closing valve.

Such a pop-up type switching device is widely used as a drain opening / closing device such as a washstand or bathtub, because it is easy to install and easy to use.

However, since the conventional pop-up type opening and closing apparatus is formed in the connection pipe 30 across the support portion 35, the space in which the water can be drained is narrowed so that the water is not drained quickly and foreign matters such as hair So that clogging of the drain hole often occurs. Further, since the support portion 35 is located deeply from the inlet of the drain hole, it is difficult to remove the foreign matter when accumulated.

Various techniques have been proposed to solve the problems of the conventional pop-up type drainage opening / closing apparatus.

First, Korean Patent Registration No. 1241107 proposed by the applicant of the present invention discloses that the support portion for fixing the opening / closing valve in the connection pipe is connected to one side rather than the inside of the connection pipe, thereby increasing the drainage space and accumulating foreign matter A technique for reducing the number of objects. The technique also proposes a technique of widening the drainage space by a structure in which the support portion is connected to a guide portion having a relatively large diameter instead of being provided on the lower side of the connection pipe, and further, the support portion is not connected to the end of the on- And a screwdriver is provided in the middle of the opening / closing valve so as to be connected to the middle, so that the depth can be reduced and the foreign matter can be easily removed. However, when foreign matters such as hair are caught on the support, there is a problem that it is necessary to pull out and remove the foreign matter, and the support has to be joined to the inside of the connector by machining.

On the other hand, in Korean Patent No. 0678385, the opening / closing valve is fixed by using a rim having a center at the center of a fastening hole for connecting the opening / closing valve, A technique has been proposed to form a step on which a rim is caught, thereby disclosing a technique capable of facilitating removal of foreign substances such as hair. However, this technique has a problem that the drainage is not made quickly because the drain hole is formed with a small size around the support piece provided on the inner surface of the rim, and the manufacturing cost is increased due to the packing provided on the outer surface of the rim.

In addition, Korean Utility Model No. 0461793 discloses that a vertical drainage duct is formed by attaching a vertical blade piece radially divided at the lower end of an opening / closing valve, so that all parts except for the vertical blade piece are utilized as a drainage passage, Way drain valve which is simple in manufacturing since the packing is not provided at the same time as the one-way drain valve. However, since the vertical drainage path proposed in this technique is attached to the lower end of the opening / closing valve, it is installed at a lower portion of the cylindrical body having a relatively small diameter, and the drainage space is not large and the drainage rate is not greatly improved. It was often easy to hang the drain pipe. In addition, since the step needs to be separately formed at the lower part of the cylindrical body in order to mount the vertical blade piece, there is a problem that the processing cost is increased and the drainage space becomes narrower due to the step, There is no element for fixing the wing piece cover integrally so that there is a problem that such an integral part is liable to be lost during operation or movement.

The present invention has been developed in consideration of the above circumstances, and it is an object of the present invention to provide a sanitary washing apparatus which can be applied to a drain port of a washstand or a bathtub to easily open and close a drain port, A pop-up type drainage opening / closing device which can be drastically reduced, can be easily manufactured, is easy to manufacture, can reduce manufacturing costs, is easy to operate, and does not lose an accessory device such as an on / off valve during operation or on the move.
