Description

  The present invention relates to a drum type washing machine provided with a protection means against a transportation load or the like during transportation.

  The conventional drum-type washing machine has a transport bracket attached to the bottom of the outer tub when packaging, and a bottom cushion that matches the bottom shape of the transport bracket is attached during packaging to position the top and bottom, and the outer tub swings up and down. When receiving the vibration and impact load on the floor, the bracket provided at the rear end of the outer tank lifted upward by the bottom buffer is fixed to the rear panel of the box with bolts, so that the outer tank It was intended to receive an additional transport load.

  For example, a transport bracket and a bottom shock absorber are provided, and the bottom shock absorber is fitted with a leg shock absorber so as not to be displaced from each other after being installed in the bottom case, and accommodates a drum type washing machine. When doing so, position the transport bracket by fitting it into the recess in the bottom cushion.

During packing or unpacking work in a drum type washing machine, for example, assuming that the height of the bottom cushion from the floor is H1, and the height of the bottom case from the floor is H2, H1 is in the range of about 150 mm to 300 mm. Yes, H2 is around 100 mm.
A transport bracket is attached to the bottom of the outer tub, and a bottom cushion that matches the bottom shape of the transport bracket is attached during packaging to perform vertical positioning and receive vibration and impact loads on the floor when it swings up and down. At the same time, a bracket provided at the rear end of the outer tub lifted upward by the bottom buffer is fixedly held by a bolt from the back of the box to receive a transport load applied to the outer tub (for example, , See Patent Document 1).

Japanese Patent Laid-Open No. 2001-219987 (page 9, FIG. 1)

  In the conventional drum type washing machine, a large space for providing a transport metal fitting and a bottom cushion for receiving a large load in the space under the outer tub is necessary, and there are significant restrictions on mounting components. In addition, the bottom shock absorber and bolts can be used for the load in the vertical direction, but when the packaging box is laid down or dropped from the corners or ridges, almost no load is applied to the bottom shock absorber. It was received only by the bolts attached to the back surface, and there were cases where surrounding parts including the bolts, such as the back panel and bracket, were deformed or damaged. Further, in order to separate the drum type washing machine from the bottom case when unpacking, it is necessary to lift the box above the height H1 of the bottom cushion, but the box of the drum type washing machine having a weight of 70 kg to 80 kg. The work of lifting was a problem for safety.

  That is, to receive the transport load at the damper part, it is necessary to secure a space directly under the outer tub, and when the packaging box falls sideways or falls from the corner part or the ridge line part, a sufficient angle cannot be secured, Furthermore, the box had to be lifted high when the bottom case and the box were separated.

The present invention has been made to solve the above-described problems, and can be easily packed and unpacked simply by attaching and detaching the spacers, and can secure a mounting volume under the outer tub, An object is to obtain a drum type washing machine that can be mounted.
In addition, the drum body that is elastically supported by the pedestal is fixed and held so that it cannot swing by simple means, protects the washing machine against transportation loads, and can be easily removed when installed at home. The purpose is to obtain a washing machine.

A drum-type washing machine according to the present invention includes a box, an outer tub accommodated in the box and supported by a support portion , an inner tub that is rotatably mounted in the outer tub and accommodates laundry. , A loading port for taking in and out the laundry from the front of the outer tub, a pedestal having legs on the lower surface and provided below the box, and between the upper surface of the pedestal and the lower surface of the support portion of the outer tub And a damper part that elastically supports the outer tub, an opening for attaching and detaching the spacer is provided on the side surface of the box, and an upper part having a U-shaped recess on the lower surface of the support part of the outer tub. A holder is provided, and a lower holder having a U-shaped recess on the upper surface of the pedestal is provided, and above these, the recess of the lower holder is oriented in the same direction on the side surface side, and a spacer having a substantially rectangular parallelepiped shape, It can be attached to and removed from the recesses of the upper and lower holders through the opening provided on the side of the box. It is obtained by way.

  The drum type washing machine according to the present invention does not use the space below the outer tub as in the prior art, but simply attaches a spacer to the damper portion, and easily fixes and holds the outer tub using a narrow space. Therefore, it is possible to secure a mounting volume under the outer tub and mount a heat pump unit or the like. In addition, the washing machine can be protected against loads, vibrations, and shocks during transportation, and sufficient strength can be ensured even when the machine is laid down or dropped from corners or ridges. Furthermore, it is not necessary to lift the box at the time of packaging and unpacking, and it is possible to work safely.
