Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an internal hose holding device in a fully automatic one-tub washing machine used in general households.

Structure of conventional example and its problems As shown in FIG. A water tank 4 supported by the machine body 3, the bottom of this water tank 4, and a drain port 5
One end is connected to this drainage pot 6 via a joint part A7, and the other end is connected to a mounting hole 9 provided in the side wall of the washing machine main body 3 via a joint part B8. It includes an internal hose 10 that is held and fixed, and an external hose 11 that is located outside the washing machine main body 3 and inserted and connected to the joint part B8, and the internal hose 10 is connected to the washing machine main body. 3, insert the internal hose 10 into the mounting hole 9 of the washing machine main body 3 as shown in Fig. 2.
This was done by inserting it from the outside. That is, to install it, first, insert the synthetic resin joint A7 connected to the drain pot 6 into the mounting hole 9 of the washing machine main body 3, and then insert the joint part B8.
The cut and raised piece 8a provided in the washing machine body 3 is deformed and inserted into the mounting hole 9 of the washing machine main body 3. By this insertion, the cut-and-raised piece 8a returns to the state shown in FIG. 2 due to its elastic restoring force, so that the wall surface of the washing machine main body 3 is held between the end face of this cut-and-raised piece 8a and the flange portion 8b, and the washing machine body 3 is Attach the fitting part B8 from the outside of the washing machine body 3 to the screw attachment hole 3a of the washing machine body 3 using the mounting screw 12.
The joint part B8 was fixed via the flange part 8b.

However, in the above conventional configuration, when attaching or removing the internal hose 10, the cut-and-raised piece 8a had to be elastically deformed and inserted into the mounting hole 9, so there was a risk that the cut-and-raised piece 8a would be damaged when deformed. In this case, if the cut-and-raise piece 8a is damaged, the internal hose 10 will not be securely fixed to the washing machine main body 3, and as a result, vibrations during use of the washing machine will cause chattering noise, etc. Not only did abnormal sounds occur, but the connection to the external hose 11 was also unstable, and if the connection became disconnected, there was a high risk that water would flow out onto the floor during drainage. In addition, the installation of the internal hose 10 is performed between the flange portion 8b of the joint portion B8 and the cut-and-raised piece 8.
Since the wall surface of the washing machine main body 3 is sandwiched and held between the end surface of the joint portion B8 and the end surface of the cut-and-raised piece 8a, the holding dimension S between the flange portion 8b of the joint portion B8 and the end surface of the cut-and-raised piece 8a is extremely accurate. For example, if the holding dimension S is too wide, it may rattle and cause abnormal noise after the internal hose 10 is installed; on the other hand, if it is too narrow, it will be difficult to install the washing machine When the joint part B8 was inserted into the hole 3, it could not be inserted reliably, and as a result, the wall surface of the washing machine main body 3 could not be clamped and fixed, causing problems such as detachment.

Furthermore, in recent years, there has been a growing trend to reduce the thickness of the wall surface of the washing machine main body 3 in order to effectively utilize resources or reduce costs. The holding dimension S of the portion B8 had to be changed, which made it extremely difficult to deal with the change.

Purpose of the invention This invention solves the above-mentioned conventional problems.
The object of the present invention is to provide an internal hose holding device for a single-tub washing machine, which allows the internal hose to be attached to and removed from the washing machine body extremely easily, and which ensures reliable attachment. be.

Structure of the invention In order to achieve the above object, the present invention has a pair of flanges protruding outward from the outer periphery of the tip of the joint part B for holding and fixing the internal hose to the mounting hole provided on the side wall of the washing machine main body. forming a section, and providing a step between one flange section and the other flange section, which is equal to or less than the plate thickness dimension of the wall surface of the washing machine main body, and said one flange section. and the other flange portion sandwich the wall surface of the washing machine main body, and the joint portion B is held and fixed to the wall surface of the washing machine main body with a mounting screw. According to this configuration,
When attaching the joint part B to the mounting hole provided in the washing machine main body, one flange part should be engaged with the end face of the mounting hole from inside the washing machine main body, and the other flange part should be attached to the inside of the wall surface of the washing machine main body. It can be installed by simply placing the screws in contact with each other and then tightening the mounting screw to the other flange from the outside of the washing machine body.On the other hand, when removing it, it is easy to do it by performing the opposite operation to the installation process, and the installation state can be changed. Since the wall surface of the main body of the washing machine is clamped and fixed between one flange part and the other flange part, joint part B is generated due to vibration during spin-drying.
This eliminates the chattering sound, and since it does not have a cut-and-raised piece that elastically deforms like the conventional one, it eliminates the problem of breakage.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In FIGS. 3 and 4, parts that are the same as those shown in FIGS. 1 and 2 in the conventional example are given the same numbers, and only the points that are different from the conventional example will be explained. That is, in one embodiment of the present invention, as shown in FIG. 3, a pair of flange portions 13a, 13b protrudes outward from the outer peripheral portion of the tip end of the joint portion B13 connected to the other end of the internal hose 10. , and one of the flange parts 13a and 13b
A and the other flange portion 13b are provided with a step _S2 that is equal to or smaller than the plate thickness dimension _S1 of the wall surface of the washing machine main body 3. The one flange portion 13a is formed at approximately 1/2 or less of the entire outer peripheral portion of the distal end of the joint portion B13.

In the above configuration, when attaching the internal hose 10 to the attachment hole 9 provided on the wall of the washing machine main body 1,
First, from the inside of the washing machine main body 3, insert one flange part 13a of the joint part B13 into the mounting hole 9 of the washing machine main body 3.
the flange portion 13a of the other flange portion 13a, and engage the flange portion 13a with the end surface of the mounting hole 9.
