Description

[Detailed Description of the Invention] The present invention relates to a drain hose for a washing machine, etc., which is formed by integrally blow-molding a hose main body and a drain port body located at the distal end of the hose main body.

Conventionally, for example, a drain hose for a washing machine has a configuration in which a drain port body having an outwardly protruding hook is fitted and bonded to the tip of a bellows-shaped hose main body, and when in use, the drain port body is guided to a drainage location. When the box is laid down on its side and not in use, a hose hook provided on the outer box is held in an upright position by supporting the hooking piece on the hook.

However, according to the above conventional configuration, the drain port body is fitted and bonded to the tip of the main body of the hose.
If the manufacturing accuracy and adhesion accuracy for fitting the two is not high, water leakage may occur.Also, when fitting and adhering, make sure that the hooking piece of the drain port body corresponds to the hose hook on the outer box. If the position is not determined, the main body of the hose must be twisted and deformed when the hooking piece is supported by the hose hooking tool, and the hooking operation becomes troublesome.

By the way, in Western-style houses, a drain port is provided in the floor that communicates with the sewer, and the tip of a drain hose or the like is inserted into this drain port to drain water. When inserting the tip of the spout into the drain hole, the hooking piece that protrudes outward gets in the way, making it impossible to insert it very deeply, and the drain spout comes off from the floor drain in the middle of draining, causing damage to the floor. There was a problem with the surface being soaked with water.

The present invention was developed in view of the above circumstances, and its purpose is to integrally blow-mold the main body of the hose and the drain port body located at the tip of the hose, and to attach the hose body to the outer circumference of the drain port body in a predetermined manner in the axial direction. At least two locking protrusions are integrally molded so as to be elastically deformable with an interval of . A ring having a ring is rotatably fitted and held, and a locking protrusion on the base end side of the drain port body is elastically deformed so that when the ring is climbed over, the ring is rotated in the axial direction. By having a movable part that can be moved, there is no need to fit and bond the hose main body and the drain port body, making it easy to manufacture and preventing water leakage.In addition, the ring can be rotated. Because of this, when the main body of the hose is twisted and deformed, the hook is not supported by the hose hook, and the hook is easy to support, and furthermore, the hook gets in the way of the drain outlet body. To provide a drain hose for a washing machine, etc., which can be deeply inserted into a drain hole formed on the floor of a room without causing the drain port body to come off from the drain hole.

An embodiment in which the present invention is applied to a washing machine will be described below based on the drawings.

First, the general structure of the washing machine will be explained.

1 is an outer box; 2 and 3 are opening/closing lids mounted on the upper surface of the outer box 1 above a washing tub and a dehydration tank (not shown), which are arranged in parallel inside the outer box 1; 4 is an outer box An operation box 1 is provided upright at the rear of the upper part of the box 1, and a towel rack 5 is provided at the top of the front panel 1a of the outer box 1.

Reference numeral 6 denotes a hose hook, which has a mounting leg 6a projecting from its base end and a hooking hole 6b formed at its tip.

The mounting legs 6a of the hose hook 6 are fitted into and engaged with mounting holes 7 formed in the upper front side of the right side plate 1b of the outer box 1.

Now, 8 is the drainage hose, which is the right side panel 1b of the outer box 1.
It is led out from the outlet 9 formed in the lower part of the
This will be explained in detail below.

10 is a bellows-shaped hose main body, and 11 is this hose main body 1.
This is a cylindrical drain port body located at the tip of the water outlet, and these are integrally blow-molded from a flexible material such as polypropylene.

A plurality of locking protrusions 12, 13, for example, two locking protrusions 12 and 13, are integrally formed on the outer periphery of a midway portion of the drain port body 11 at a predetermined distance from each other in the axial direction so as to be elastically deformable during the blow molding. These locking protrusions 12, 13
The space between them is defined as a fitting portion 14.

Furthermore, a drain port body 11 that is continuous with the tip of the hose main body 10 is provided.
A regulating protrusion 15 is integrally formed on the outer periphery of the base end portion during the blow molding, and the locking protrusion 13 and the regulating protrusion 15
The movable portion 16 is the proximal end portion between the two.

Reference numeral 17 denotes a ring formed by turning the hooking piece 17a outward, and its inner diameter is set to the drain opening body 11, that is, the fitting part 14.
and a locking protrusion 1 that is slightly larger than the outer diameter of the movable portion 16.
2, 13 and the regulating protrusion 15, and its upper and lower width dimensions are preset to be slightly smaller than the upper and lower width dimensions of the fitting part 14. ing.

Then, the ring 17 is fitted into the drain port body 11 from the front end opening 11a side, and the locking protrusion 12 located on the front end opening 11a side is elastically deformed to overcome this and fit into the fitting part 14. In this state, movement in the axial direction is restricted by the two locking protrusions 12 and 13, and it is held rotatably.

Next, the operation of this embodiment having the above configuration will be explained.

First, when not in use, pull up the drain port body 11, which is the tip of the drain hose 8, and close the hooking piece 17a of the ring 17.
The hose hook is inserted into the hook hole 6b of the tool 6 from above to support the hook.

In this case, since the ring 17 is rotatably fitted and held in the fitting part 14, the hose main body 10 is held in an upright state without being twisted or deformed (see FIG. 2).

On the other hand, when the hose is used for washing, the hook 17a of the ring 17 is removed from the hook hole 6b of the tool 6, the drain hose 8 is laid down, and the drain port body 11 is guided to an appropriate drainage location. However, in this embodiment, a case where the drainage location is a cylindrical drainage port 20 formed in the floor 19 of the room 18 through the sewer line as shown in FIG. 1 and FIG. 4 will be described.

That is, the ring 17 is caused to ride over the locking protrusion 13 located on the base end side of the drain port body 11 by elastically deforming the locking protrusion 13, and the ring 17 is moved over the movable portion 16.
into the mating position.

Therefore, the ring 17 can freely move in the axial direction within the range of the movable portion 16, and in this state, the drain port body 11 is inserted into the drain port 20 from its front end opening 11a side.

This causes the ring 17 to move relatively upward, allowing the drain port body 11 to be inserted as deeply as necessary.

In this case, it goes without saying that the outer diameter of the two engagement protrusions 12 and 13 is set to be slightly smaller than the inner diameter of the drain port 20.

As described above, according to this embodiment, the hose main body 10 and the drain port body 11 located at the distal end thereof are integrally blow-molded, and a predetermined interval exists between them in the axial direction on the outer periphery of the drain port body 11. In this way, at least two locking protrusions 12,1
3 is shaped so that it can be elastically deformed, and these locking protrusions 12
, 13, the hose hook attached to the outer box 1 is connected to the fitting 6, and the ring 1 has a hooking piece 17a.
7 is rotatably fitted and held, there is no need to fit and bond the hose main body 10 and the drain port body 11, making it easy to manufacture and preventing water leakage. Even if the hooking piece 14 is supported by the hooking hole 6b of the hose hook 6 in order to place the hose 8 in an upright state, the ring 17 is rotatable, so the hose main body 10 is in a twisted state unlike the conventional case. There is no such thing as being held in place, and the hose is mainly 10
The hanging operation facilitates the supporting operation, and the hose main body 10 does not deteriorate due to twisting.

Furthermore, according to this embodiment, the locking protrusion 13 located on the base end side of the two locking protrusions 12 and 13 is elastically deformed on the base end side of the drain port body 11. Since the ring 17 is provided with a movable part 16 that can move in the axial direction when the ring 17 is climbed over, the drainage area is located on the floor 1.
In the case of drain port 20 of No. 9, drain port body 11 is connected to ring 1.
The hanging piece 17a of No. 7 can be inserted as deeply as necessary into the drain port 20 without being obstructed by the hooking piece 17a, and the drain port body 11 will not come off from the drain port 20 when draining water, and the floor will be covered with water. There is no risk that 19 will be flooded.

Moreover, according to this embodiment, since the regulating protrusion 15 is provided at the base end of the drain port body 11, the movable part 1
The ring 17 located at 6 does not unnecessarily move to the hose main body 10, which is convenient for handling.

Although the above embodiment is a case in which the present invention is applied to a washing machine, the present invention is not limited thereto, and can similarly be applied to, for example, a dehydrator or a dishwasher having a drain hose.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with various modifications without departing from the gist, for example, the regulating protrusion 15 may be provided as necessary. .

As explained above, the present invention consists of integrally blow-molding the main body of the hose and the drain port body located at the tip thereof, and at least two stripes on the outer periphery of the drain port body at a predetermined distance from each other in the axial direction. The locking protrusions are formed on the body so that they can be elastically deformed, and between these locking protrusions, the hose hook of the outer box of a washing machine, etc. is supported, and a ring having a hook piece can be rotated. The ring is fitted and held and is movable on the proximal end side of the drain port body so that the ring can move in the axial direction when the ring is moved over by elastically deforming the locking protrusion on the proximal end side. Since the hose main body and the drain port body do not need to be fitted and bonded, manufacturing is simple and there is no risk of water leakage.Furthermore, since the ring is rotatable, the hose main body can be When the hook is twisted and deformed, the hook is not supported by the hose hook, and the hook is easy to support and operate.Furthermore, the drain outlet body can be placed on the floor of the room without the hook getting in the way. To provide a drain hose for a washing machine or the like which can be deeply inserted into a formed drain port and prevents the drain port body from coming off from the drain port.
