DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coupling for a washing machine pan, and more particularly, to a washing machine capable of securely connecting a washing machine drain trap and a washing machine drain hose and of easily attaching and detaching. The present invention relates to a joint for bread.

[0002]

2. Description of the Related Art Washing machine pans provided with a drainage trap for washing machines are usually installed at places where washing machines are installed in apartment houses and the like. The drain trap has a structure in which bubbles do not flow back onto the pan during drainage, and is formed so that water flowing on the pan can be drained smoothly. Further, the bread has a weir portion of an appropriate height around the bread so as to prevent overflow of water on the surrounding floor. Therefore, a normal washing machine pan does not assume that the washing machine is moved, and the drain trap does not assume that the washing machine drain hose is frequently attached and detached.

[0003]

However, some apartment houses have a design that does not take into consideration the installation of a washing machine in a room. However, the installation location is naturally limited due to the positional relationship around the water, which may make it difficult to open and close the door and make it difficult for people to pass.

[0004] For this reason, it is conceivable to move the washing machine to a position where it is not in the way except when the washing machine is in use. could not. Further, when the drain trap is installed in accordance with the floor surface, when the drain trap is clogged, there is a possibility that bubbles and water may flow backward to contaminate the floor surface. Therefore, in such a case, it is desired that the upper surface of the washing machine pan be flush with the surrounding floor and the drain trap be disposed below the pan.

However, if the drainage hose is directly inserted into or removed from the drainage trap, the flexible drainage hose may be damaged. Further, if a simple joint is used, the drainage performance becomes extremely poor, or the drainage trap is cleaned. The problem that it becomes impossible to perform is generated.

Accordingly, the present invention provides a washing machine pan in which the drain hose can be easily attached to and detached from the drain trap when the washing machine has to be moved, and the drain trap can be easily cleaned. It is intended to provide a joint for use.

[0007]

In order to achieve the above object, a washing machine pan joint according to the present invention is provided with a washing machine installation pan at a predetermined interval above a washing machine drain trap. A threaded socket joint is joined to the inlet of the trap, a rubber ring type socket joint is detachably screwed to the threaded socket joint, and an elbow joint is attached to the tip of the washing machine drain hose. It is characterized in that it can be attached to and detached from the rubber ring type socket joint through a through hole provided in the pan.

[0008]

FIG. 1 is a longitudinal sectional view showing one embodiment of a washing machine bread joint according to the present invention. This washing machine pan joint is for detachably connecting a washing machine drain hose 13 to a washing machine drain trap 12 installed below the washing machine installation pan 11.
In this case, a device having a foam backflow prevention function similar to that of a normal washing machine drain trap is used. Further, a waterproof pan 14 is provided around the drain trap 12 to prevent water from overflowing under the floor.

The drain trap 12 is provided with a rectifying projection 16 on the outer periphery of the lower end of a foam backflow prevention pipe 15 having an inlet 15a for connecting a drain hose at the upper end.
When cleaning the inside of the drain trap 12, it is necessary to remove the upper lid 17, remove the odor stopper tube 18, and then pull out the foam backflow prevention pipe 15 upward.

The pan 11 placed above the drain trap 12 is provided such that the upper surface thereof is flush with the surrounding floor so that the washing machine can be easily moved. At a corresponding position, a through hole 20 for inserting an elbow joint 19 attached to the tip of the drain hose 13 is provided.
Is provided.

A spigot 21a of a threaded socket joint 21 having an outer diameter smaller than the opening diameter of the upper lid 17 is fixed to the inflow port 15a of the foam backflow prevention pipe 15 by bonding or the like. The male screw part 22a of the rubber ring type socket joint 22 is detachably screwed and joined to the female screw part 21b of the socket joint 21.

Further, a rubber ring mounting groove 22c for mounting the rubber ring 23 is provided on the inner periphery of the receiving port 22b of the rubber ring type socket joint 22. This rubber ring mounting groove 22
c is such that the amount of protrusion of the rubber ring 23 from the inner surface of the receiving port 22b is a necessary minimum so that the outer diameter of the elbow joint 19 slidably in contact with the mounted rubber ring 23 and inserted into the receiving port 22b can be as large as possible. It is formed so that it may be limited. Therefore, the outer diameter of the rubber ring mounting groove 22c is larger than the outer diameter of the threaded socket joint 21, that is, the opening diameter of the upper lid 17.

Here, it is possible to directly join the elbow joint 19 to the inflow port 15a of the foam backflow prevention pipe 15, but when a packing (rubber ring) is attached in consideration of smooth attachment / detachment and waterproofness. When the rubber ring mounting groove is formed in the elbow joint 19 or an appropriate clearance with the rubber ring is taken into consideration, the inner diameter of the elbow joint 19 becomes extremely small, and the drainage property is greatly reduced. Although it is possible to form the drainage trap 12 exclusively and form the bubble backflow prevention pipe 15 with a large diameter, it is extremely expensive because of lack of versatility.

Therefore, as described above, the threaded socket joint 21 whose outer diameter is smaller than the opening diameter of the upper lid 17 is fixed to the inlet 15a of the foam backflow prevention pipe 15, and the rubber ring is attached to the threaded socket joint 21. A rubber ring socket joint 22 having an outer diameter of the groove 22c larger than the opening diameter of the upper lid 17 is detachably screwed and joined, and an elbow joint 19 attached to the tip of the drain hose 13 is connected to the rubber ring socket joint 22. Is inserted through the through hole 20 of the pan 11 and held by the rubber ring 23 attached to the rubber ring type socket joint 22, so that the drain trap 12
It is possible to obtain good drainage while enabling disassembly and cleaning of the wastewater.

That is, when the drain trap 12 is disassembled, the pan 11 is removed in a state where the elbow joint 19 is removed from the rubber ring socket joint 22, and then the rubber ring socket joint 22 is screwed into the socket joint. By removing the screw-in type socket joint 21 from the foam backflow prevention pipe 15 by removing the screw-in type socket joint 21 from the
Can be removed upward, so that the inside of the drain trap can be cleaned in the same manner as a normal drain trap.

Since the rubber ring 23 is mounted so that the amount of protrusion of the rubber ring type socket joint 22 to the inner periphery is minimized, the diameter of the elbow joint 19 to be joined to the rubber ring type socket joint 22 is reduced. The elbow joint 19 can be easily inserted and removed as compared with a case where the joints are directly joined to each other, and sufficient waterproofness can be obtained. Further, since an elbow joint 19 made of a hard material, for example, a synthetic resin is attached to the tip of the drain hose 13, the drain hose 1
By holding the elbow joint 19 when attaching and detaching 3, the drainage hose 13 is not damaged. Further, by using the elbow joint 19, the tip of the drainage hose can be connected in the horizontal direction, so that water does not form in the drainage hose. The drain hose 13
And the elbow joint 19 are joined by a normal tightening band 24.
Can be done using

[0017]

As described above, according to the joint for a washing machine bread of the present invention, when the washing machine is moved, the washing machine drain hose can be easily and reliably attached to and detached from the drain trap. In addition, the drainage trap can be easily cleaned without the drainage property being impaired.
