Description

[0001] Drainage Trap Having No Hinge Means [0002]

The present invention relates to a drain trap, and more particularly, to a drain trap which is installed in various sewers or drains, and can prevent odor from coming out from a sewer pipe or a drain pipe. The present invention relates to a drain trap of a non-hinged valve type.

Drainage traps are installed in various sewer or drainage wells and are widely used to prevent foreign matter from entering the drainage pipe or drainage pipe to block the pipe. Normally, water or small foreign matter is omitted, but foreign matter having a certain size or more is filtered. A typical drainage trap is a drainage trap of a net type having a plurality of small holes. However, when a drain trap is used, it is impossible to prevent the odor from flowing backward from the sewage pipe or the drain pipe. It is because of the smell coming from many small holes in the net. Thus, various means have been conventionally provided to prevent backflow of odors. For example, I installed a lid on the sewer to prevent odor. However, it is very troublesome to open and close the lid every time you use it.

For this problem, a U-trap has been used as a drain trap with a common odor barrier function. This is to prevent the backflow of odor by bending the tube and allowing the water to float over the bended area. However, it has a problem that it occupies a large volume and it is difficult to remove the foreign substance when it is stuck.

Thus, a more simple and easy-to-use drainage trap has been proposed. For example, according to Korean Utility Model Registration Application No. 20-2009-0000538, a molding sleeve having a tubular shape with an open upper portion and a drain hole communicating with a drain hole on a bottom surface; And a tubular bezel insert corresponding to the drain hole having an upper drain hole so that a lower end thereof is inserted into the drain hole and communicated with the drain hole and water is allowed to flow over the upper end thereof. This prior art claims that the construction is very simple and easy to install and the like, but it is difficult to say that it is a simple structure.

Also, Korean Utility Model Registration Application No. 20-2010-0010473 also discloses a drainage trap having a drainage piece penetrating through the center so as to communicate with a drainage pipe, a fresh water space having an upper portion opened to receive wastewater around the drainage passage, A sealing ring formed on an outer side of the fresh water space and formed in a part of an outer periphery of the fresh water space; a sealing ring inserted in the sealing groove to prevent leakage of wastewater in the fresh water space; And a discharge member including a blocking member for blocking backflow, wherein the discharge member is formed with a plurality of connection pipes through which drainage holes are penetrated, and an outer peripheral portion of the discharge member is inserted into the sealing groove to seal the sealing ring, A female screw coupled to the male screw is formed on the inner periphery, a center of the upper surface is protruded so as to protrude from the inner periphery, The discharge member is positioned between the fastener and the body portion so that the lower portion of the sealing member is brought into close contact with the sealing ring by the lead movement caused when the fastener is screwed into the body portion by pressing the upper surface of the pressing member. A plurality of discharge pipes are coupled to the respective connecting pipes to prevent reverse flow of the odor coming from the discharge pipe and to discharge the wastewater collected at a plurality of places at once to improve the drainage efficiency. However, this prior art also has a problem in that the number of parts is increased and the manufacturing cost is increased, and there is a problem that durability and operational stability may be deteriorated by foreign substances.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto. First, a drain trap according to an embodiment of the present invention will be described with reference to FIGS. 1 to 2. FIG.

The drain trap according to the present invention includes a ring body (100), a valve (200), and a valve opening / closing means as main components.

The ring body 100 is ring-shaped so that the drain body 100 is fitted into the drain hole and the drain hole 111 is formed in the middle. Although the ring body 100 is shown in a simple form, a step (not shown) or the like may be provided on the outer side surface of the ring body 100 to fit a frame (not shown) provided in the sewer or the sewer. The ring body 110 constituting the ring body 100 may be hollow or filled with synthetic resin.

The valve 200 is installed at the bottom of the ring body 100 so that the drain hole 111 can be opened and closed. The valve 200 is installed at the bottom of the ring body 100 so that it can be opened or closed in the same manner as a hatch. It is preferable that there is no or minimal gap between the contact surface of the valve 200 and the ring body 100. The valve 200 includes an insertion portion 210 fitted to the bottom of the ring body 100 and a flange 220 protruding laterally from the lower end of the insertion portion 210 to be in contact with the bottom surface of the ring body 100 .

The valve opening / closing means is such that the ring body 100 and the valve 200 are opened in a hinged manner by the weight of water falling from above, and when the water falls downward, the drain opening 111 is closed by closing.

The valve opening / closing means according to the embodiment of the present invention includes a spring 230 having one end connected to one side of the ring body 100 and the other end connected to one side of the valve.

A first spring hole 211 is vertically formed at one side of the valve 200 and a second spring hole 121 vertically aligned with the first spring hole 211 is formed in the ring member 100, . The spring 230 may be a tension coil spring. The spring 230 is inserted into the first and second spring holes 211 and 121 so that the spring 230 is not exposed to the outside. The second spring hole 121 may be sealed by an upper stopper 122.

A first pinhole 213 is formed in the valve 200 in the lateral direction. The first pinhole 213 communicates with the first spring hole 234. The first pin 234 is inserted into the first pinhole 213 and is fitted to the lower end of the spring.

The ring body 100 is provided with a second pinhole 123 in the lateral direction. The second pinhole 123 is provided by a sleeve 120 protruding from the inner peripheral surface of the ring body 100.

The second pinhole 123 communicates with the second spring hole 121. A second pin 233 is fitted in the second pinhole 123 and is fitted in the upper part of the spring. As a result, the spring 230 is configured to be disconnected from the outside air when water is drained, that is, when the valve is opened.

The upper portion of the valve 200 partially fits into the inside of the ring body 100. And it is not allowed to flow in the fitted state. According to the embodiment of the present invention, the insertion portion 210 is protruded from the upper portion of the valve. The drain hole 111 of the ring body has a flat cross-sectional shape in which the insertion portion 210 can be closely fitted.

A protrusion 212 is provided at the lower end of the valve and a spring 230 extends to the protrusion 211. Therefore, the spring 230 can have a sufficiently long length. This protrusion 212 allows the valve 200 to be opened more easily by the principle of the lever.

"의 평면 형상을 가진다. 그리고 배수공(111)도 이와 같은 형상으로 되어 있다. 도 4에 도시된 것처럼 삽입부(210)는 장방형으로 되어 있으되 1개의 짧은 직선구간(243)과 상대적으로 기다란 대칭을 이루는 2개의 직선구간(241,242)을 포함하며 도 4에 도시된 것처럼 진원(C) 안에 들어오게끔 되어 있으므로 3개의 원호(244,245,246)를 포함하고 있다. According to the embodiment of the present invention,

4, the insertion portion 210 is rectangular and has a relatively long symmetry with respect to one short straight line section 243, as shown in FIG. And includes three arcs 244, 245, 246 since it is included in the circle C as shown in Fig.

Since the insertion portion 210 is rectangular, the long side portions 241 and 242 serve as guides for the valve 200 to be opened and closed. The rear end hinge point 220a of the valve 200 becomes the center of rotation when the valve 200 is opened and closed. The sewage falling on the valve 200 is collected in the storage space S provided by the ring body 100 and the valve 200 and acts to push the valve 200 down by its own weight. Then, since the valve 200 is connected to one side by the spring 230, the other side is opened as shown by a dot-dash line in FIG. The spring 230 is stretched due to the tensile force and the valve 200 is easily opened by the principle of the lever by a small force with the hinge point 220a between the point where the spring 230 is connected and the rear end thereof as the center of rotation do. When the water flows out and the load applied to the valve 200 disappears, the spring 230 receives an elastic force to be restored to its original position, and the valve 200 is closed again. The shape of the insertion portion 210 of the valve 200 guides the valve 200 to be opened and closed in a hinged manner so as not to flow left and right. A step 112 is provided on the bottom surface of the ring body so that the rear end does not come into contact with the valve body 200 when the valve 200 is opened.

The valve 200 is preferably made of a lightweight material. The force or speed at which the valve 200 is opened and closed according to the elastic force of the spring 230 may be adjusted. A packing 113 may be interposed in the contact area between the valve 200 and the ring body 100 to improve the water tightness and to reduce the generation of noise when the ring body 100 is closed. When the valve 200 is closed, the odor coming from below the sewer is blocked.

On the other hand, if the weight of the valve 200, the elastic force of the spring, and the storage space S are appropriately adjusted, a certain amount of water may be contained in the storage space S. Then, the blocking effect of the smell may be further exacerbated by the water in the storage space (S). The above-mentioned packing 113 can help prevent water from flowing out.

Hereinafter, another embodiment of the present invention will be described with reference to Figs. 6 to 7. Fig. 6 is a cross-sectional view of a drain trap according to another embodiment of the present invention. 7 is an attempt to lower the valve 200 of the drain trap according to another embodiment of the present invention.

The present embodiment is for adjusting the minimum torque that must be applied to open the valve 200. A rail 250 is provided on the bottom surface of the valve 200 in the longitudinal direction and a weight weight 251 is coupled to the rail 250 to move along the rail. The weight 251 is tightly coupled to the rail 250 and does not move unless it is applied with a force. By moving the weight 251 in the direction of the arrow, it is possible to adjust the aforementioned minimum torque amount.

If the valve is not opened properly or is opened too easily according to the personal use environment, the weight 251 may be adjusted so as to match the user's environment.

According to the present embodiment, the lower end hook 232 of the spring 230 is hooked to the loop 214 provided in the lower stopper 212. According to the present embodiment, the first pinhole 213 and the first pin 113 of the valve are not required. Therefore, it is possible to simplify the configuration of the valve 200, thereby reducing manufacturing costs.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 8 is a longitudinal sectional view of a valve of a drain trap according to another embodiment of the present invention. The present embodiment is intended to more effectively transmit torque to the valve so that the valve 200 is opened or closed naturally. According to the present embodiment, the middle portion of the upper surface 260 of the valve is depressed. Therefore, it is possible to accommodate more water than that space. Therefore, the effect of reducing the volume of the ring body 100 can be obtained. After the water flows, the weight of the valve 200 becomes lighter and can be closed more quickly.

The above description is only an example based on the technical idea of the present invention. Those skilled in the art will recognize that various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. For example, all embodiments described above may be freely combined and practiced by those skilled in the art, and any combination thereof should be construed as being included within the scope of the present invention.
