Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a trap device for drainage basins, and is used, for example, in places where wastewater flowing out from a kitchen or bathroom joins a sump basin or an invert basin. This invention relates to improvements in trap devices.

(Prior Art) Conventionally, trap devices such as S-shaped traps or curved traps have been installed in kitchens, bathrooms, etc., and these trap devices prevent odors from downstream of the drain pipe from entering the room. However, there are cases where a trap device is not installed at the drain from a washing machine or the drain from a bathtub.In such cases, in order to install a trap device again, it is necessary to A trap device must be installed in or before the confluence of pipes. However, drainage equipment from kitchens, bathrooms, etc. is generally installed in narrow areas of the premises, and there is little space for piping, making piping work extremely difficult.

(Problems to be solved by the invention) Therefore, as described in Japanese Utility Model Publication No. 17589/1989, a pocket part and a U-shaped groove are provided in one box, and the invert function and trap function are combined. A device with a built-in device has been proposed. With this device, the piping space does not need to be very large, there are few piping parts, and piping work is easy. However, since the trough of the above structure is a dedicated trough, there is a problem that if an existing trough is used, this trough cannot be used.

The present invention has been developed in consideration of the above points, and provides a drainage manhole trap device which does not require a trap to be placed in the middle of the piping from the kitchen, bathroom, etc., but can be placed directly inside the manhole, and which can be easily installed not only in new construction but also in existing manholes, and which can also be easily cleaned.

[Structure of the idea]

(Means for Solving the Problems) The trap device for a drainage basin of the present invention has an outlet at one end of a trap body disposed in the drainage basin with an outlet opening on the upper surface, and a trap device located above the outlet to seal the water. A pipe connection port is formed in the partition wall and communicates only with the lower part of the outflow port, and the trap body is rotatably provided with a lever having an eccentrically formed pressing portion projecting to the pipe connection port. It is something to do.

(Function) The trap device for drainage basins of the present invention places the trap body inside the drainage basin, connects the tip of the drainage pipe inserted into the drainage basin to the pipe connection port, and then rotates the lever to The pressing part protrudes to the pipe connection port and strongly presses the drain pipe, thereby reliably preventing the drain pipe from coming off. In this state, the waste water from the drain pipe passes through the trap body and falls into the drainage basin from the upper end of the outlet. Even if the inflow of waste water from the drain pipe is interrupted, the waste water is always accumulated up to the upper end of the outlet of the trap body, so the odor in the drainage basin will not flow back into the drain pipe.

When cleaning is to be carried out, the lever is rotated to move the eccentric pressing part back from the pipe connection port, the drain pipe is pulled out from the pipe connection port, and the trap body is taken out from the drainage basin.

(Example) Next, an example of the present invention will be described based on the drawings.

Figure 1 shows the drainage basin trap device.
is a drainage basin, which is supported by four supporting parts 2 and has a lower basin body 5 provided with a groove part 4 communicating with a plurality of socket holes 3 in the center part, and is fitted into the upper part of this lower basin body 5. It is formed of a cylindrical upper cage 8 having an insertion hole 7 through which the drain pipe 6 is inserted, and a lid 9 that closes the upper opening of the upper cage 8.

Reference numeral 11 denotes a trap body, which is formed of a lower body 12 and an upper body 13, as shown in FIGS. 2 to 4.

The lower main body 12 is formed into a substantially bowl shape, and its upper surface is entirely open. A locking step portion 14 is provided approximately halfway around one side of the circumferential surface at approximately the center in the vertical direction.

The upper body 13 also has a pipe connection port 15 at one end.
It has a cylindrical part 16 forming a cylindrical part 16, and a substantially rectangular cylindrical water-sealing partition wall 17 that extends in both directions continuously from the cylindrical part 16 and is bent downward by about 90 degrees to form an elbow shape. An outlet 18 is opened at the other end. Furthermore, a locking step portion 19 is formed on the inner circumferential surface of the cylindrical portion 16 . Furthermore, this cylindrical portion 16
As shown in FIGS. 5 and 6, a pressing port 20 is formed on one side, and a substantially U-shaped lever receiver 21 is formed at the periphery of the pressing port 20, protruding from the outer surface of the cylindrical portion 16. has been done.

This upper body 13 has a water sealing partition wall 17 inserted through the upper surface opening of the lower body 12, and this water sealing partition wall 17
The lower edges of the three sides located on the pipe connection port 15 side are fixedly bonded to the locking step portion 14 of the lower main body 12. In this state, the upper body 1 of the upper surface opening of the lower body 12
The part not covered by 3, that is, the upper body 13
An outflow port 22 is formed between one surface of the lower body 12 opposite to the pipe connection port 15 and the other half circumferential surface of the lower main body 12 .

Further, reference numeral 23 denotes a lever, which, as shown in FIGS. 5 and 6, consists of an operating rod 24 and a pressing portion, for example, an eccentric cam 25, which is provided at the tip of the operating rod 24 and has a serrated peripheral surface. ing. In this lever 23, an eccentric cam part 25 is rotatably supported by a shaft 24a as shown by the arrow on the lever receiver 21, and an operating rod 24 is rotated around the cylindrical part 16 as shown by the solid line in FIG. When the eccentric cam part 25 is parallel to the plane, the eccentric cam part 25 does not protrude into the pipe connection port 15, and the operating rod 24 is connected to the cylindrical part 1 as shown by the two-dot chain line in FIG.
6, the eccentric cam portion 25 projects into the pipe connection port 15.

Next, the operation of this embodiment will be explained.

Normally, when using this device, the trap body 11 is placed inside the drainage basin 1, and the tip of the drainage pipe 6 inserted through the insertion hole 7 of the drainage basin 1 is inserted into the pipe connection port 15 of the upper body 13. After the connection is made, the operating rod 24 of the lever 23 is rotated from the parallel state to the vertical state. Then, the eccentric cam portion 25 protrudes into the pipe connection port 15 and strongly presses the drain pipe 6 against the inner peripheral surface on the other side of the cylindrical portion 16, thereby reliably preventing the drain pipe 6 from coming off.

In this state, the drainage from the drainage pipe 6 passes through the upper body 13 and falls into the drainage basin 1 from the upper end of the outlet 22 of the lower body 12. Even when the inflow of waste water from the drain pipe 6 is interrupted, the waste water always accumulates up to the upper end of the outlet 22 of the lower main body 12, so that the odor in the drainage basin 1 does not flow back into the drain pipe 6.

Next, when cleaning this device, after removing the lid 9 of the drainage basin 1, move the operating rod 24 to the cylindrical part 1.
6.Turn it into a state perpendicular to and parallel to 6.
Then, the eccentric cam portion 25 is housed in the pressing port 20 and is no longer protruded into the pipe connection port 15.
The drain pipe 6 can be easily pulled out from the pipe connection port 15. The trap body 11 from which the drain pipe 6 has been removed can be taken out from the upper opening of the drainage basin 1.

Therefore, cleaning of the drainage basin 1, trap body 11, and drainage pipe 6 becomes easy.

In addition, the lever 23 has an eccentric cam portion 25 that urges the drain pipe 6 in the insertion direction when the drain pipe 6 is connected, and in the withdrawal direction when the drain pipe 6 is removed.
Insertion and withdrawal are easy and reliable.

In the embodiment described above, the pressing portion of the lever 23 is formed on the eccentric cam portion 25 and has a sawtooth peripheral surface, but it may be flat. In addition, the trap body 11
Although the upper main body 13 and the lower main body 12 are configured, they may be formed integrally. At this time, the water-sealing partition wall 17 does not need to be formed into a rectangular tube shape;
The portion located below the upper edge may be a planar wall surface.

[Effect of idea]

According to the present invention, by rotating the lever, the pressing part protrudes from the pipe connection port and connects the drain pipe by pressing, so the trap body and the drain pipe can be easily attached and detached, and the drainage basin, trap body, and drain pipe can be cleaned. It is easy to do, prevents clogging, and can be easily opened even if it becomes clogged.

In addition, it can be easily attached to existing drainage basins, and in the case of new construction, there is no need to install a U-shaped trap that is difficult to clean in front of the drainage basin, simplifying piping work.

Furthermore, the trap body can be formed into a small size and can be easily installed inside the drainage basin.
