Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fixing device for a washing tub (also used as a dewatering tub) of a single tub type washing machine.

[0002]

2. Description of the Related Art When packaging electrical products, various cushioning materials are housed in a cardboard box together with the device for the purpose of holding the device body and its accessories so that they will not move inside the cardboard box. . Among such electric appliances, the one-tub washing machine is provided with a device for fixing the washing tub during transportation because the washing tub is supported in a floating state.

A conventional fixing device for fixing a washing tub is made of foamed plastic, and has a structure to prevent the play by fitting it into the washing tub and engaging with the opening of the main body of the washing machine. There is. The foamed plastic is a material having an appropriate elasticity for protecting the equipment and having an excellent cushioning function, and since it is easy to mold, it has an advantage that it can be easily molded according to the shape of the washing tub portion.

[0004]

However, although the foamed plastic material itself has extremely excellent characteristics, various problems have recently arisen due to problems in processing after it has been used as a cushioning material for packaging. For example, it is a big social problem that it is discarded as household waste because the collection route is undeveloped. In order to prevent this, handling at the time of collection takes time and the collection cost becomes high.
In addition, when incinerating and discarding, it requires high energy, so maintenance of the incinerator is required. From these facts, particularly in European countries, it is the current situation that incineration is extremely disliked and the foamed plastic itself is not used.

In addition to this, the cushioning material using foamed plastic has the drawbacks of being extremely bulky, having low transportation efficiency, increasing transportation costs, and requiring a large storage space. Therefore, as a substitute for foamed plastics, there has been a widespread demand in the industry for corrugated cardboard packaging materials that are easy to assemble and easy to assemble as well as having a cushioning function.

[0006]

Therefore, the present inventor has achieved the present invention as a result of earnest research in view of the above problems, and is characterized in that a one-tub washing machine is packed. In the one for fixing a washing tub provided in a floating state to the one-tub type washing machine, an erection part and two erection parts, each of which is made up of two members intersecting in an X shape, erected around the main body opening part at a tip end thereof. Crossed with a vertical board made of corrugated cardboard, which has a contact portion for directly or indirectly contacting the washing tub below and a notch portion provided between the contact portion and the intersection. The vertical plates are held and fixed to each other by fitting them into the bottoms of the vertical plates, and the notch parts fitted to the engaging parts projecting on both sides of the notch part of the vertical plates have a substantially central part. By corrugated cardboard fixed plates provided at four places on the periphery Was made, the fixing plate is to bent portion is provided substantially linearly through the notch portion and the central portion other than the cut portion of the peripheral edge.

The term "vertical plate" as used herein refers to a vertical opening extending over a main body opening around the upper part of a washing tub which is also used as a dehydrating tub of a single-tub type washing machine. And a plate-like member having a lower end provided with a contact portion for directly or indirectly contacting the washing tub. That is, the washing tub is fixed by engaging both the stationary portion of the main body of the single-tub washing machine and the washing tub supported in a floating state. Indirectly contacting means engaging with other cushioning members or protective members attached to the washing tub, or engaging with accessories such as a lid provided in the washing tub. In the present invention, an installation portion for engaging with the main body opening is provided at the tip of the vertical plate, and a contact portion for contacting the washing tub directly or indirectly is provided below the installation portion. The two vertical plates are used as a set of two intersecting in an X shape, and are arranged almost on the center line of the washing tub.

The vertical plate is made of double-sided corrugated board or double-sided double-sided corrugated board, but it may be folded in two to increase the strength. In this case, it is preferable to bend the corrugated board so that the corrugated steps intersect with each other in order to enhance the strength. The main body opening is a portion above the washing tub where the main body of the washing machine is opened and does not move with respect to the washing tub supported in a floating state. Usually, in a one-tub type washing machine, a water receiving tub is provided as an outer tub on the outside of the washing tub, and a part for contacting the water receiving tub may be provided at the tip of the vertical plate. Further, the vertical plate is provided with a cutout portion between the abutting portion and the crossing portion intersecting in the X shape.
Therefore, the portion that intersects with the portion provided with the contact portion is in a state of protruding downward due to the cutout portion.

The term "fixed plate" refers to a plate-shaped member that is fitted into the bottom of a vertical plate that is cross-connected in an X-shape to hold the space between the two vertical plates. That is, the fixing plate holds the vertical plate by engaging with the engaging portions projecting on both sides of the notch formed in the bottom of the vertical plate. For this reason, the fixed plate is provided with four notches for fitting into the engaging portions on both sides of the notch of the vertical plate at the central portion and the peripheral edge. In addition to the function of holding the vertical plate, the fixing plate may directly or indirectly contact at least a part of the peripheral portion of the fixing plate with the washing tub.

It is preferable that the notch has the same shape as the engaging part of the vertical plate to ensure the holding, but in order to facilitate the assembly and disassembly, the engaging part on the crossing side is particularly preferable. In addition to the X shape, the notch portion to be engaged with may have a circular shape, an elliptical shape, a square shape, or the like. Further, when the fixing plate is attached to the X-shaped vertical plate, in order to ensure the engagement between the engaging portion and the notch, locking such as providing a notch at the base of the engaging portion Means are preferably provided.

In the present invention, this fixed plate is provided with a bent portion that passes through substantially the central portion. The bent portion is for bending the fixing plate substantially at the center. In other words, it can be bent to make it easier to attach to and remove from the vertical plate, or it can be bent and fitted into the vertical plate for mounting, and then straightened to make the engagement between the notch and the engaging part stronger. There is an advantage that can be. Also, by bending, it becomes possible to fit the accessories such as a lid provided on the washing tub and other cushioning members.
