Abstract

PROBLEM TO BE SOLVED: To install a washing machine horizontally simply and with high precision by covering rotatably the opening part of a frame body to be provided with a washing dewatering basket, providing a level at an upper surface cover having a panel box part and a clothing throw-in opening part. SOLUTION: The fully automatic washing machine possesses an outer basket 5 having a washing dewatering basket 2 internally, and this outer basket 5 is supendingly supported by means of a vibrationproof device 7 from the upper end four corners of a frame body 1. In this case, a cylindrical level 37 is provided at an upper surface cover 15 part that is to be covered with a lid body 25 at the time of the state of the lid body 25 being closed, This level 37 is fitted to a housing part made up of the upper surface cover 15 and a level cover 38 so as to be parallel with the upper end surface of the frame body 1. By providing the level 37 at the upper surface cover 15 like this, the number of parts relating to the precision of a level fitting surface becomes only the four parts of a leg, a base 34, the frame body 1 and the upper surface cover 15, so higher precision horizontal adjustment becomes possible. Also, an opening between the frame body 1 and the outer tank 5 can be minimized, and the minimization of the size of the frame body 1 can be realized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine which can be installed horizontally.

[0002]

2. Description of the Related Art In a fully automatic washing machine, an internal mechanism portion including a washing / dehydrating tub and an outer tub having a drive unit attached to the lower portion thereof is suspended and supported by a vibration isolator from four corners of an upper portion of a frame. Therefore, if the floor surface of the installation location is inclined, the main body is inclined, the suspended internal supporting mechanism is biased, and the gap between the outer tank and the frame is changed.

This gap is a gap required for the dehydration operation to be completed normally even if the clothes in the washing / dehydrating tub are offset, so if the gap changes due to the inclination of the main body, the outer tub during dehydration Will collide with the frame, or the safety switch will activate and operation will stop halfway, which will prevent normal dehydration.

Therefore, the fully automatic washing machine requires horizontal installation of the main body. Therefore, in order to simplify the horizontal installation work, the fully automatic washing machine is mounted on the level and the legs at the four corners of the lower part of the frame. A fully automatic washing machine including a dust piece is described in Japanese Patent Laid-Open No. 768080.

[0005]

However, in the conventional example, the leveling device is mounted on the front panel, which is fixed to the frame with the mounting screw through the top cover, as shown in FIG. Therefore, there are many parts related to the levelness in the level mounting surface, and due to the accumulation of dimensional errors for each part, there may be a case where the level indicated by the level and the actual level of the main unit are misaligned. It was

Further, in future full-automatic washing machines, since the size of the frame remains the same, only the washing capacity tends to increase and the outer tub tends to be large. Therefore, more horizontal installation and accuracy will be required.

As another problem of the conventional example, since the spirit level is installed close to the input switch section and the display section, even if horizontal level is completed and the spirit level is no longer needed, There was a level in the place where it was attached, and there was a point that the designability was impaired.

An object of the present invention is to provide a fully automatic washing machine which is simple and can be installed horizontally with high accuracy.

It is another object of the present invention to propose a fully automatic washing machine in which the designability is prevented from being deteriorated by installing a level in the design section.

[0010]

[Means for Solving the Problems] To achieve the above object,
By installing a spirit level on the top cover of the fully automatic washing machine body, the number of parts related to the levelness of the leveling surface is reduced, and the deviation between the level indicated by the spirit level and the actual level of the main body is reduced. To do.

Further, when the lid body for opening and closing the clothes throwing opening in the top cover is closed, a spirit level is installed in the portion covered by the lid body to close the lid body. Then it makes the spirit level invisible.

[0012]

[Operation] By installing the spirit level on the top cover, the number of parts related to the accuracy of the level mounting surface is 5 points (leg, base,
From the frame, top cover, and front panel), the number of legs, base, frame, and top cover can be reduced to four points, making horizontal installation easier and more accurate.

By installing the spirit level in the portion of the top cover covered by the lid, the spirit level cannot be seen when the lid is closed, and the design can be improved.
