JP4490258B2 - Fixing device for washing tub in fully automatic electric washing machine - Google Patents

Description

The present invention relates to an improvement of a fixing device for a washing tub (also used as a dewatering tub) of a fully automatic electric washing machine.

  When packaging electrical products, various cushioning materials are housed in the cardboard box together with the equipment in order to keep the equipment body and its accessories from moving inside the cardboard box. Among such electric products, the fully automatic electric washing machine has a washing tub supported in an idle state, and therefore it is necessary to provide a device for fixing the washing tub during transportation.

  As fixing devices for protecting the laundry tub by fixing it, foamed plastic that is easy to mold and excellent in cushioning performance, and a structure in which cardboard is folded and assembled are mainly used. As a means for fixing the washing tub, a buffer body is fitted into the washing tub and a main body opening opened at the top of the washing tub as in the packaging shock absorber shown in Patent Document 1, and is fixed across the body. Has been adopted.

As a fully automatic electric washing machine, there exists a thing of the structure which provided the water receiving tub provided with the inner cover on the outer side of the washing tub. In the case of such a structure, it is necessary to fix both the washing tub and the water receiving tub over the main body opening by a fixing member. In this structure, the fixing member must be interposed under the inner lid. For this reason, the inner lid may be in a half-open state and interfere with the lid of the main body.

  The conventional corrugated cardboard fixing device has a drawback that the work efficiency is remarkably lowered, such as a large number of parts and complicated assembly. Furthermore, molded products such as foamed plastic and pulp mold have a problem that the space portion is bulky and bulky, resulting in high transportation costs and storage costs.

  In particular, in recent fully automatic electric washing machines, there are many models in which a plurality of detergent inlets and garbage inlets are provided on the inner surface of the washing tub, and if these are not adjusted to a predetermined position, a fixing member can be fitted. There was a situation that could not be done, which led to a decrease in work efficiency.

Further, in the case of a fully automatic electric washing machine having a structure with an inner lid, the fixing member opens the inner lid and is interposed thereunder, so that the inner lid is in a half-opened state, causing a problem of interference with the main body lid. For this reason, conventionally, the fixing member is provided as far as possible on the front side of the inner lid so that the inner lid is not opened so much that it hardly interferes with the main body lid. However, in this method, there are few parts which engage a washing tub or a water receiving tub with a fixing member, and the effect which protects a washing tub will fall remarkably. Moreover, the presence of the detergent inlet of the washing tub as described above has been a greater problem for the purpose of reliably engaging the fixing member in a narrow range such as the washing tub.

  Therefore, the present inventors have made the present invention as a result of intensive studies in view of the above problems, and the feature of the present invention is that the first invention of the present invention is free to play in a fully automatic electric washing machine. A corrugated cardboard device for fixing the washing tub by crossing and contacting a washing tub provided in a state and a main body opening opened above the washing tub, and a flat plate-like main body fitted into the opening An upright portion extending on both sides of the flat body and contacting the opening; and a side end formed on the flat surface by cutting into the flat body and bent to the back side. And the tank support part to be brought into contact with.

  In the second invention of the present invention, a washing tub provided in an idle state in a fully automatic electric washing machine, a water receiving tub provided with an inner lid on the outer peripheral side of the washing tub, and a main body opening above the washing tub A corrugated cardboard device for fixing the washing tub by being brought into contact with the opening, and a flat plate body fitted into the main body opening under the inner lid, extending on both sides of the flat plate body A standing portion that is brought into contact with the opening, formed by cutting into the flat plate-like body, bent to the back side, and the side end portion is brought into contact with the inner circumference of the washing tub and the water receiving tub. The object is to be constituted by a tank fixing member comprising a tank support part and a belt-like member that is fitted along the main body opening and has a main body cover support part that supports the main body cover in a half-open state.

  Here, the “flat main body” in the present specification refers to a member that fits into a main body opening that opens above the washing tub of a fully automatic electric washing machine. The flat main body is formed of a flat corrugated cardboard material, so that the inner lid can be prevented from opening much even when it is interposed in almost the entire area below the inner lid. The structure is such that a standing part that makes contact with the opening of the main body of the fully automatic electric washing machine is extended on both sides to contact the inner periphery of a washing tub or water receiving tub that also serves as a dehydration tub for the fully automatic electric washing machine. The tank support is provided on the flat plate body itself.

  The tub support portion is formed by cutting, and has a structure in which the side end portion is brought into contact with and engaged with a washing tub or the like by bending the back surface side. The flat plate-like main body can be provided in almost the entire area of the washing tub or the like, and a large number of tub support portions can be provided so as to be in contact with the entire circumference of the washing tub or the like. For this reason, even when a part of the tank support part is aligned with a position such as a detergent inlet of the washing tank, it is possible to make up with another tank support part. Moreover, since the tank support portion is structured to be engaged with the inner periphery of the washing tub or the like while being bent, it can be supported by being pushed into the detergent inlet or the like while the side end portion is being deformed or stopped in the middle. .

  The fixing device of the first invention and the tank fixing member of the second invention have the same structure, and these can be stored and transported in the form of a plate, and can be used as they are without being assembled in advance. First, if you place it on the opening of a fully automatic electric washing machine and push the flat body toward the opening, the standing part bends and touches the periphery of the opening, and the flat body is above the washing tub, etc. Located in. And a work is completed only by bend | folding a tank support part below and making these side edge parts contact inner periphery, such as a washing tub. When the inner lid is provided, it is supported by the upper surface of the flat plate-like body. In addition, when the inner lid that is half-opened and the main body lid interfere with each other, the upper end of the standing portion may be used as a main body lid support portion to support the main body lid in a half-open state.

  “Strip-shaped member” is a member used in combination with the tank fixing member in the second invention of the present invention, and is mounted along the upper surface of the flat plate-shaped main body and the inner surface of the main body opening from the base of the inner cover to support the main body cover. A strip of cardboard. For this reason, the notch forming part matched with shapes, such as an inner lid and a fixture, is formed in a lower end part, and the main body cover support part is formed in the upper end part. By interposing this belt-like member between the tank fixing member and the main body lid, the main body lid is supported in a somewhat open state, and interference between the inner lid and the main body lid is prevented. The main body lid is supported by a cushioning material for protecting the main body at the time of packing, or fixed by means such as a tape stopper.

The belt-like member is attached so as to be along the opening of the main body while bending the creased portions provided at several places. In this case, it may be simply placed on the upper surface of the flat plate-like main body, but an insertion piece or the like may be provided to be fitted and supported in a gap existing above the washing tub or the like. In addition to holding the inner lid so as not to be opened with an adhesive tape or the like, the belt-shaped member may be supported by providing an inner lid pressing portion by cutting. The inner lid pressing part can also be provided on the standing part in the first invention.

  The fixing device of the first invention and the tank fixing member of the second invention include a flat plate-like main body that fits into the main body opening, a standing part that makes contact with the periphery of the main body opening, a tank support that makes contact with the washing tub, etc. It is a structured structure, can be used as it is without being assembled, and can improve the efficiency of packing work. Moreover, since the tank support part is pushed into the washing tub while manually folding the cardboard material, it can be easily handled even if the washing tub is provided with a detergent inlet, and can be engaged at an arbitrary position. And since a main body is flat form, even if it provides so that the whole washing tub etc. may be covered, the opening of an inner cover does not become large. For this reason, even when there is an inner lid, it can be supported by the tub support section over the entire area of the washing tub or the like.

Even when the inner lid opened by providing a flat main body interferes with the main body lid, interference is avoided by holding the main body lid in a half-open state at the upper end of the standing portion that is in contact with the main body opening. be able to. Furthermore, by using together with the tank fixing member a band-shaped member that is fitted along the main body opening portion and has the upper end portion as the main body lid support portion as in the second invention of the present invention, the support of the main body lid is simply made more reliable. In addition, the standing portion of the tub fixing member can be held along the main body opening, and the effect of making the holding and fixing of the washing tub and the like more reliable is produced.

The flat plate-shaped main body that fits into the opening of the washing machine main body, the standing portion that touches the periphery of the opening, and the tank support that fits into the washing tub, etc. are formed of a flat corrugated cardboard material, thereby solving the above-mentioned problems. did.
