DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain trap provided on a washing machine pan and connected to a drain hose attached to the washing machine.

[0002]

2. Description of the Related Art Conventionally, as a structural example of a drain trap provided in a pan for a washing machine and connected to a drain hose attached to the washing machine, for example, one having a structure shown in FIG. 2 is known. .

In this figure, a drain trap denoted by reference numeral 1 comprises a trap main body 1a mounted on a washing machine pan (not shown) and a drain hose mounting cylinder 1b connected to the center of the upper surface of the trap main body 1a. , This drain hose mounting cylinder 1b
The drain hose 2 fitted to the drain hose mounting cylinder 1b
The drain mounting tube 1b is formed so as to be inclined with respect to the horizontal plane when the trap body 1a is mounted on the washing machine pan when the trap body 1a is mounted on the washing machine pan. Have been.

The drain hose 2 is fitted to the drain hose mounting cylinder 1b of the drain trap 1 from substantially obliquely above the drain trap 1 and then fastened by a fixed band 3 to thereby form the drain trap 1 Is to be connected to.

[0005]

By the way, in such a conventional drain trap 1, since the drain hose mounting tube 1b is provided toward the side of the strap body 1a, the drain hose mounting tube is provided. In some cases, it is difficult to confirm the state of attachment of the fixed band 3 for fixing the drain hose 2 to 1b, or there may be a problem such as forgetting to attach the fixed band 3, and due to these, the drain hose 2 and the drain hose are attached. There is a problem that water leaks at the connection with the cylinder 1b.

Further, since the drainage hose mounting cylinder 1b extends in the horizontal direction, when an external force acts on the drainage hose 2, the external force is applied along the connection direction between the drainage hose mounting cylinder 1b and the drainage hose 2. And the drainage hose 2 is easily detached.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. The present invention is designed to securely connect to a drainage hose to prevent water leakage and to minimize inadvertent disconnection. An object of the present invention is to provide a drain trap provided in a washing machine pan that can be prevented.

[0008]

In order to achieve the above object, the present invention relates to a drain trap provided on a pan for a washing machine and to which a drain hose attached to the washing machine is connected. A trap body attached to the machine pan,
A connection plug attached to the tip of the drainage hose, and a plug mounting tube formed integrally with the trap body and detachably connected to the connection plug, wherein the plug mounting tube extends in a vertical direction. A locking mechanism is formed between the connection plug and the plug mounting cylinder, and a locking mechanism for engaging and disengaging the both is provided. The operating lever for engaging and disengaging the locking mechanism is provided on the connection plug. Is provided.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
This will be described with reference to FIG. A drain trap indicated by reference numeral 10 in FIG. 1 is provided in a washing machine pan, and is connected to a drain hose 11 attached to a washing machine (both not shown). A trap body 10a, a connection plug 12 attached to the tip of the drain hose 11, and a plug mounting cylinder 10b formed integrally with the trap body 10a and to which the connection plug 12 is detachably connected. , The plug mounting cylinder 10
b is formed along the vertical direction, and a locking mechanism 13 for engaging and disengaging the connection plug 12 and the plug mounting cylinder 10b is provided between the connection plug 12 and the plug mounting cylinder 10b.
2 has a schematic configuration in which an operation lever 14 for engaging and disengaging the locking mechanism 13 is provided.

More specifically, the drain hose 11 is fitted to one end (upper end in the drawing) of the connection plug 12 and is integrally fixed by bonding or the like. The other end of the connection plug 12 can be inserted into the plug mounting tube 10b. Further, a tip of the connection plug 12 is formed inside the plug mounting tube 10b when inserted into the plug mounting tube 10b. The seal ring 16 to be pressed against the step portion 15 is fixed.

In the present embodiment, the locking mechanism 13 is made of a spring material, and a pair of engaging pieces 1 that are swingably mounted on the side surface of the connection plug 12 by utilizing its elasticity.
7, the operating lever 14 provided integrally with the end of the engagement piece 17 on the swinging side, and positioned so as to be exposed from the side surface of the connection plug 12; Are inserted into the plug mounting cylinder 10b, the engaging holes 18 into which the engaging pieces 17 are fitted and locked.
In a state where these engaging pieces 17 are engaged with the respective locking holes 18, the seal ring 16 is compressed and deformed by the step portion 15,
The space between the connection plug 12 and the plug mounting cylinder 10b is closed in a liquid-tight state.

The drain trap 10 according to the present embodiment thus configured is fixed to the washing machine pan by fixing the trap body 10a to the washing machine pan, and the fixed state. In the above, the plug mounting cylinder 10b is held along the vertical direction.

In this state, the connection plug 12 mounted on the drain hose 11 is inserted into the plug mounting cylinder 10b from the distal end thereof, and the seal ring 16 provided on the distal end is inserted into the plug mounting cylinder 10b. Step 15 inside
To each of the engagement pieces 1 of the locking mechanism 13.
7 is engaged with the locking hole 18.

By such an operation, the connection plug 1
2, the relative movement of the plug mounting cylinder 10b in the detaching direction is restricted, and the connection plug 12 and the plug mounting cylinder 10b are liquid-tightly connected by the seal ring 16. The connection plug 12 and the plug mounting cylinder 10b thus connected are connected to the plug mounting cylinder 1 described above.
Since 0b is provided along the vertical direction, these fitting portions are visible over the entire circumference, so that their connection state can be easily visually confirmed. Here, the operation of confirming the connection state can also be performed by confirming whether or not each of the operation levers 14 is returned to a predetermined position, which is combined with the fact that the fixed band becomes unnecessary. , Connection plug 12 and plug mounting cylinder 1
0b is securely connected, and the occurrence of water leakage is minimized.

On the other hand, since the plug mounting cylinder 10b is provided along the vertical direction, when an external force acts on the drain hose 11, most of the external force is applied to the connection plug 12b.
Acts so as to be substantially perpendicular to the connection direction between the plug mounting cylinder 10b and the plug mounting cylinder 10b.

The various shapes, dimensions, and the like of the components shown in the above embodiment are merely examples, and can be variously changed based on design requirements and the like.

[0017]

As described above, according to the drain trap provided in the pan for a washing machine according to the present invention, since the plug mounting cylinder is provided along the vertical direction, these fitting portions can be formed over the entire circumference. It is possible to see over
These connection states can be easily confirmed visually, and the connection between the connection plug and the plug-mounting cylinder is securely performed to minimize the occurrence of water leakage, in combination with the elimination of the fixing band. You can stop it.

In addition, since the plug mounting cylinder is provided along the vertical direction, when an external force acts on the drain hose,
Most of the external force is applied so as to be substantially perpendicular to the connection direction between the connection plug and the plug mounting cylinder.
The disconnection of the connection plug can be effectively suppressed.
