Description

  The present invention relates to a drainage trap that is made compact in order to increase the storage space in a cabinet such as a washstand and a kitchen.

Conventional drainage traps such as washstands and kitchens are provided with S-shaped drainage traps (for example, Patent Document 1), which are generally used and popularized.
However, since the S-shaped drain trap is exposed in a cabinet such as a wash basin and a kitchen, there is a problem that the inside of the cabinet becomes narrow, and each member is removed when cleaning the inside of the drain trap. There is a problem that it takes a lot of time and labor to take out the stored items out of the cabinet, and people have to sink into the cabinet and clean it.
In recent years, high-pressure cleaning is sometimes performed periodically for cleaning the piping, and the contents in the cabinet have to be taken out of the cabinet each time high-pressure cleaning is performed.

Therefore, by providing a trap mechanism that is inclined to the back side of the cabinet and close to the drainage port, the storage space in the cabinet is increased and cleaning from the drainage port is enabled, thereby eliminating the trouble of cleaning. A drain trap has been proposed (for example, Patent Document 2 and Patent Document 3).
However, since such a drain trap is inclined toward the back side of the cabinet, there is a problem that the direction of the drain trap is set and the workability is deteriorated.

  ADVANTAGE OF THE INVENTION According to this invention, the drainage trap with favorable cleaning property and workability is provided, ensuring the storage space in cabinets, such as a washstand and a kitchen.

It is side view sectional drawing of the drain trap A in the Example of this invention. It is a top view of the flange 4 in the Example of this invention. It is a side view of the quick fastener (20) connection part of an Example. It is the quick fastener of an Example. It is side surface sectional drawing in another Example of this invention. It is side surface sectional drawing in another Example of this invention.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a side sectional view showing a state in which a drain trap A according to an embodiment of the present invention is attached to a drain outlet B of a sink.
A flange 2 (flange member) is inserted into the drain B of the sink. A trap outer 11 is attached to the flange 2 using a lock nut 3. A trap cup 12 is provided inside the trap outer 11. In this embodiment, the trap cup 12 is formed separately from the trap outer 11, but can be integrally formed. Hereinafter, the trap outer 11 and the trap cup 12 are collectively referred to as a trap body 1.

A deodorizing cylinder 4 is inserted into the trap body 1 through the drain port B. Drainage that flows from the top of the deodorizing cylinder 4 flows into the trap cup 12. When waste water exceeding the capacity of the trap cup 12 flows, the waste water flows into the trap outer 11 beyond the upper end of the trap cup 12.
Note that the lower end of the trap outer 11 is connected to a drain pipe C (not shown). The drain pipe C is connected to the building pipe, and the waste water that flows into the trap outer 11 flows out to the sewage pipe.
When the inflow of the drainage stops, the drainage that cannot exceed the upper end of the trap cup 12 stays inside the trap cup 12. This drainage makes it possible to prevent the atmosphere in the drain pipe C from flowing back to the upstream side through the drain trap A.

In the drain trap of the present invention, the drain port B is formed so that the flange 2 is connected substantially horizontally.
Since this flange 2 does not have a peculiar structure compared with the flange used for the connection of the S-shaped trap used conventionally, it is possible to use a common member. Thereby, interchangeability with a general drain trap becomes possible, and versatility can be given to the flange.

  Further, the flange 2 can be omitted by connecting the trap outer 11 directly to the drain B of the sink. In this case, since there is no step between the flange 2 and the drainage port B, the effect of improving the cleanability around the drainage port B can be obtained.

  In the drain trap of the present invention, the deodorizing cylinder 4 is detachably installed on the flange 2. As a result, when the deodorizing cylinder is removed, the drain trap can be cleaned from the sink by using a commercially available brush or the like, and the contents stored in the cabinet are taken out each time the drain trap is cleaned. There is no need.

  The deodorizing cylinder 4 is detachably installed on the flange 2, and a gap is provided between the trap cup 12 and the trap outer 11. Thereby, when the deodorizing cylinder 4 is removed, high-pressure washing can be performed from the sink, and there is no need to take out the stored items in the cabinet each time high-pressure washing is performed.

  In the drain trap of the present invention, the trap outer 11 is inclined downward from the drain port B, and accordingly, the deodorizing cylinder 4 is also inclined downward. Thereby, a space is secured in front of the drain trap A, and the storage space in the cabinet can be used effectively.

  In the drain trap according to the present invention, the portion of the deodorizing cylinder 4 that is in contact with the flange 2 is a connecting portion 41 that extends vertically downward downward, and the lower portion of the connecting portion 41 is a bent portion 42 that is inclined to the back side. Yes. That is, the portion of the deodorizing cylinder 4 that comes into contact with the flange 2 and the connecting portion 41 are not directional in the horizontal direction, and the flange 2 does not require a specific direction. Therefore, the flange 2 has a horizontal freedom with respect to the drain B of a sink.

Further, the connecting portion 41 extends downward from the contact portion between the deodorizing cylinder 4 and the flange 2. As a result, when the deodorizing cylinder 4 is attached / detached, it is possible to pull the connecting portion 41 straight up by an extended distance. Thereafter, when it is further pulled upward, the bent portion 42 of the deodorizing cylinder 4 and the trap body 1 come into contact with each other and can be automatically extracted in an oblique direction. That is, the user can attach and detach the deodorizing cylinder 4 without being aware that the drain trap A is inclined.
In the state where the deodorizing cylinder 4 is attached, a space exists between the upper part of the bending part 42 in the bending direction and the trap body 1. Without this space, the upward movement of the deodorizing cylinder 4 is hindered by the contact between the bent portion 42 and the trap body 1. If this space is substantially the same as the length of the connection part 41 of the deodorizing cylinder 4, when the bending part 42 and the trap main body 1 contact, the bending part 42 of the deodorizing cylinder 4 will be pulled out from the drain outlet B upward. It is preferable because the user can recognize that the deodorizing cylinder 4 is bent.

  In the drain trap of the present invention, the deodorizing cylinder 4 has a knob 43 at a position exposed in the drain port B. As a result, the deodorizing cylinder 4 can be pulled upward without touching the wet location in the drain trap. In addition, it can be inserted into the flange 2 attached to the drain outlet B with the knob 43 when mounting.

  In the drain trap of the present invention, an O-ring seal 44 is installed at the contact portion between the deodorizing cylinder 4 and the flange 2. Thereby, it is possible to prevent the odor and the like inside the trap outer 11 from leaking from the outer periphery of the deodorizing cylinder 4.

FIG. 2 shows a top view of the flange 2 in the embodiment of the present invention.
In the drain trap of the present invention, the flange 2 has a substantially circular shape, and an opening for attaching and detaching the deodorizing cylinder 4 is opened in a substantially circular shape at a substantially center. Thereby, when fixing the flange 2 to the drain port B with the lock nut 3, it can fix without worrying about the directionality of the flange 2. FIG. If the flange 2 has directionality, it will try to force its orientation after fixing, and the flange 2 may be damaged or the fixing may loosen and cause water leakage, but the present invention reduces these risks. I can do it.

FIG. 3 shows an enlarged view of a connecting portion between the flange 2, the lock nut 3, and the trap outer 11 in the embodiment of the present invention.
The flange 2 is fixed to the drain B by a lock nut 3 from below.
Further, the lock nut 3 and the trap outer 11 are connected via the quick fastener 5. The lock nut 3 has a collar part at the lower part and the trap outer 11 at the upper part, and the quick fastener 5 connects the two parts by sandwiching the collar part. At this time, since the lock nut 3 and the trap outer 11 are connected to each other in a rotatable state, the drain trap body 1 can be rotated to adjust the direction even after being connected by the quick fastener 5 at the time of construction. Is possible.
In addition, by providing the lock nut 3 with two functions of fixing the flange 2 and connecting the drain trap body 1, the number of members can be reduced, and a more compact drain trap A can be obtained. Contributes to increased space.

FIG. 4 shows a detailed view of the quick fastener 5 used in the embodiment of the present invention.
The quick fastener 5 includes a fastener main body 51 that surrounds the lock nut 3 and the flange 2, and a rotating body 52 that is rotatably locked to the fastener main body 51.
One end of the rotating body 52 is rotatably attached to the fastener main body 51 by a hinge portion 53. Further, the other end of the rotating body 52 is locked to the locking portion 54 of the fastener main body 51, so that the lock nut 3 and the flange 2 are surrounded and fixed.
At this time, a portion of the rotating body 52 connected to the hinge portion 53 is configured to apply a force in the opening direction, and the rotating body 52 naturally moves in a direction away from the fastener body 51. As a result, when the installer forgets to lock the end of the rotating body 52 to the locking portion 54, or when the locking is not surely released, the rotating body 52 is opened and the installer notices. Cheap.

FIG. 5 is a side sectional view showing a state in which the drain trap A according to another embodiment of the present invention is attached to the drain outlet B of the sink. In addition, the same code | symbol is attached | subjected to the same member as the Example already demonstrated, and description is abbreviate | omitted.
In this embodiment, the drainage port B is configured separately from the sink. The distribution port B is formed integrally with the flange 2. Of course, the lock nut 3 for connecting the drain port B and the flange 2 is not necessary, and is omitted.
The drain trap body 1 (trap outer 11) is connected using a flange 2 and a quick fastener 5.
With this configuration, it is possible to prevent filth from accumulating around the flange 2 and to further reduce the number of members.

Although the present invention has been described above using specific embodiments, the present invention is not limited to the above specific examples. In the range which does not deviate from this invention, it is possible to design a material, a shape, etc. suitably.
For example, as shown in FIG. 6, the trap cup 12 and the trap outer 11 may be integrally molded to reduce the number of parts. Further, the O-ring seal 44 attached to the contact portion between the deodorizing cylinder 4 and the flange 2 may be designed to have two places at the top and bottom to further reduce the rattling of the deodorizing cylinder 4.
