Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a washing machine with an improved outer case reinforcement structure.

[Technical background of the invention]

For example, in a dehydrating/washing machine, a reinforcing plate is formed by bending a piece of steel into a rectangular cylinder with an open top, and a substantially triangular reinforcing plate with supporting parts for hanging rods for suspending the tub at the four corners of the top opening. were attached by welding to form the outer box.

[Background technology issues]

However, in the top-mounted configuration, reinforcing plates for reinforcing the corners of the outer box and supporting the hanging rods are required for each corner, which requires a large number of parts, and each of them must be fixed by welding one by one. Therefore, there was a problem of poor manufacturability.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a washing machine that can simultaneously strengthen the outer case and support the hanging rod, reduce the number of parts, and improve manufacturability.

[Summary of the invention]

The present invention has an outer box with an open top surface, an inner wall portion and an outer wall portion that are installed along the upper edge of the outer box and fit on both the inner and outer sides of the upper end of the outer box, and the tank is suspended. The outer box reinforcing frame is provided with an integrally formed support part for receiving hanging slings, and a cover that is disposed on the top surface of the outer box reinforcing frame and has a laundry entrance/exit. It is characterized in that the outer case is reinforced by fitting into the upper end of the outer case, and the hanging rod is received by an integrally formed support part.

(Embodiments of the Invention) A first embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Reference numeral 1 denotes an outer box, which is made of, for example, a pre-painted steel plate, so-called decorative steel plate, and is bent into a substantially rectangular cylindrical shape with open upper and lower surfaces and the middle part of the back. A connecting plate 2 is fixed to the upper surface of the connecting plate 2 by caulking or the like. Then, a flange portion 3 extending inward at each side edge of the upper end of this outer box 1 is formed by bending,
In addition, cutouts 3a are formed at both ends of each flange portion 3 so as not to get in the way when the decorative steel plate is bent into a rectangular cylindrical shape. Reference numeral 4 denotes a reinforcing frame for the outer box made of plastic, which is formed into a generally rectangular frame shape along the upper edge of the outer box 1. Specifically, it is inserted into the flange 3 of the outer box 1 from above. A frame main body part 6 has substantially diagonal plate-shaped support plate parts 5 at the four corners of the frame, and both inner and outer walls 7 are integrally provided on both the inner and outer sides of the frame main body part 6 so as to extend downward over the entire circumference. ,8
It is equipped with Reference numeral 9 denotes a holding portion for receiving a hanging rod, which will be described later, and is formed integrally with each support end plate portion 5 of the outer box reinforcing frame 4, by recessing approximately the center of the support plate portion 5. A hemispherical recess 10 is formed, a through hole 11 is formed at the bottom of the hemispherical recess 10, and an annular wall 12 is provided protruding from the open upper edge of the hemispherical recess 10. Reference numeral 13 denotes a pair of hand grips, which project integrally from the outer wall portions 8 located on both left and right sides of the outer box reinforcing frame 4. Thus, the outer box reinforcing frame 4 configured in this manner has the outer wall portion 8 fitted to the outer circumferential side of the upper end of the outer box 1 and the inner wall portion 7 fitted to the inner circumferential side of the flange portion 3 of the outer box 1. ,
The flange portion 3 of the outer case 1 is attached to the upper peripheral edge of the outer case 1 so as to sandwich the flange portion 3 from both sides of the inside thereof, and is fixed to the flange portion 3 by screws 14. Reference numeral 15 denotes four hanging rods constituting a well-known elastic suspension mechanism, each of which has a hemispherical sliding body 16 attached to its upper end, which is supported by the outer box reinforcing frame 4. It is housed in a hemispherical recess 10 of the portion 9 and is disposed in a hanging state within the outer box 1.

Reference numeral 17 denotes a water receiving tank, which has a rotary tank 18 rotatably disposed therein, and a well-known drive mechanism 19 for driving the rotary tank 18 attached to the outer bottom. The lower part is elastically connected to the lower end of the hanging rod 15 to be elastically suspended within the outer box 1. Reference numeral 20 denotes a substantially rectangular cover having a hanging wall portion 20a around the outer periphery, a rectangular recess 21 is formed approximately in the center of the upper surface of the cover, and a substantially internal laundry entrance/exit 22 is formed within this rectangular recess 21. ing. Reference numeral 23 represents a lid for opening and closing the laundry entrance/exit 22, and 24 represents an operation box integrally installed at the rear of the cover 20. The operation box 24 is provided with a timer device 25 and the like.

Then, the cover 20 has its hanging wall portion 20a fitted onto the outer circumferential side of the positioning ribs 26 which are arranged intermittently in a rectangular shape on the upper surface of the frame main body 6 of the outer box reinforcing frame 4,
It is fixed to the positioning rib 26 by a screw 27.

Now, according to the dehydrating and washing machine having the above configuration, the following effects are achieved.

(a) The outer box 1 is made from a flat decorative steel plate, first by bending the flange portion 3, and then bending it into a rectangular cylinder shape, and each flange portion 3 of the outer case is made so that it does not get in the way during the bending.
0 It is necessary to form notches 3a at both ends, so the flanges 3 are separated, and the outer box 1 alone is weak against external forces.For example, when subjected to a lateral force, the outer box 1 becomes diamond-shaped. It is easily deformed. However, due to the attachment of the outer box reinforcing frame 1, each flange portion 3 is sandwiched between the inner and outer walls 7, 8 of the outer box reinforcing frame 4, and the upper edge of the outer box 1 is shaped like a rectangular cylinder of the outer box reinforcing frame 4. Since the outer box 1 is held in its regular shape, it is possible to reliably prevent the outer box 1 from being deformed even if an external force is applied. This eliminates the need for four reinforcing plates, which were conventionally welded to each of the four corners to reinforce the outer box, reducing the number of parts and eliminating the welding process, greatly improving productivity. I can do it. However, even if the conventional reinforcing plate provided with the support part for the hanging rod is eliminated, the supporting part 9 for receiving the hanging rod 15 is integrally formed in the outer box reinforcing frame 4, so that the support for the hanging rod 15 can be easily removed. There is no need to provide a separate section.

(b) In addition, in conventional systems in which a reinforcing plate is welded to the outer box, if the outer box is made of decorative steel plate that has been painted in advance, the coating may peel off during welding or the welding strength may be insufficient. It is difficult to make the outer case made of decorative steel plate because of the problem that The reality is that the outer box and reinforcing plate were painted after a truly tedious process such as drying. On the other hand, in this embodiment, the welding process can be omitted as described above, so the outer case 1 can be made of decorative steel plate, which makes it possible to omit the painting process of the outer case 1 and further improve manufacturability. It is possible to improve the

(c) In addition, especially if the inner wall portion 7 of the outer box reinforcing frame 4 is provided over the entire circumference of the flange portion 3 as in this embodiment, it is possible to prevent the flange portion 3 from being bent inward. Even if a local pressing force acts on the side surface of the outer box 1, deformation can be prevented, and so-called stickiness of the outer box 1 can also be prevented.

(d) Furthermore, since the outer box reinforcing frame 4 has a handle portion 13 shaped like a square, it goes without saying that you can efficiently transport the washing machine by holding your hand on the handle portion 13. After unscrewing the screws 14, the water tank 17, drive mechanism 19, etc. can be taken out from the outer box 1 by lifting the hand grip 13, which is very convenient for repair and inspection.

(e) In addition, since the hanging wall portion 20a of the cover 20 is fitted to the outer case reinforcing frame 4 on the outside of the positioning rib 26, positioning with respect to the outer case reinforcing frame 4 when installing the cover 20 can be easily performed. This can improve assembly work efficiency, and furthermore, it is possible to reliably prevent the cover 20 from shifting after installation.

Next, FIG. 5 to FIG. 6 show a second embodiment of the present invention, and the difference from the first embodiment is that the inner wall portion 27 of the outer box reinforcing frame 4 is attached to the outer box only at the four corners. The outer box reinforcing frame 4 is attached to the upper edge of the outer box 1 by fitting the inner wall 27 and the outer wall 8 to both the inner and outer sides of the flange 3. However, the inner and outer walls 27 of the four corners
．． Since the four corners can be held in a fixed shape by sandwiching the flange portion 3 by the flange portions 28, the outer box 1 can be sufficiently reinforced.

Further, in the third embodiment shown in FIG. 7, unlike the first embodiment, the cover 20 and the operation box 24 are formed separately, and in the fourth embodiment shown in FIG. A positioning protrusion 28 is provided on the inner side of the box to protrude downward, and a receiving recess 29 is formed in the frame main body 6 of the outer box reinforcing frame 4 to engage with the positioning protrusion 28. It goes without saying that the same effects as in the first embodiment can be obtained even if the configuration is as shown in FIGS.

In each of the above embodiments, the outer box 1 was made of decorative steel plate, but
The present invention is not limited to this, and the outer box 1 may be formed of an unpainted steel plate and then painted. Even in this case, the outer box 1 may be painted in a simple rectangular cylindrical form without a conventional reinforcing plate. This makes painting work easier. Further, the handhold portion 13 does not necessarily need to be integrally molded with the outer box reinforcing frame 4, and may of course be attached separately. It is not limited to this, and the main subject can be changed and implemented without departing from the gist.

〔Effect of the invention〕

As described above, the present invention is capable of holding the outer box in its regular shape with the outer box reinforcing frame, thereby reinforcing the outer box, and also supporting the hanging rods. It is possible to provide a washing machine that can eliminate the need for welding to the wafer, thereby reducing the number of parts and improving manufacturability.
