Abstract

PURPOSE:To constitute a washing machine so that a throw-in port of a drum can be closed up automatically at the time of starting a rotation of the drum even if a cover body of the drum is not locked completely or it is forgotten to close a cover body of the drum by controlling an operation of a motor so that the rotation starting direction of the drum in each position of washing, dehydration, etc., becomes the reverse direction to the closing direction of the drum cover. CONSTITUTION:When a cover body 67 is allowed to slide in the direction as indicated with an arrow A, throw-in port C 68 is opened. Also, when it is allowed to slide in the reverse direction to the arrow A, the throw-in port C 68 is closed, and simultaneously, a detaining claw 77 is detained to a claw 73 to be detained, and the cover body 67 is locked in a closed state. When each cycle for starting a drum is started, first of all, a microcomputer 80 rotates a drum 44 in the reverse direction to the direction for closing the cover body 67. Subsequently, after executing the operation for one second, the rotation of the drum in each process is varied to a regular operation. That is, in the washing and drying cycles, the drum 44 is brought to positive inversion at a low speed, and in the dehydrating cycle, the drum 44 rotated in one direction at a high speed.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a drum type washing machine.

(B) Conventional technology As a conventional example, an outer tub is supported within a frame, a horizontal wheel type washing drum is rotatably supported within the outer tub, and by rotating the washing drum, the washing drum is loaded into the drum. A washing machine for washing and drying washed laundry is disclosed in JP-A-50-25058 (92(5)8.42).

In this washing machine, a clothes input port is provided on the outer peripheral wall of the washing drum, and a lid for opening and closing this input port is slidably provided on the outer peripheral wall of the drum.

(c) Problems to be Solved by the Invention In the conventional example, if the lid was not completely closed after loading clothes, when the drum rotated for washing or dehydration, the laundry would fall into the loading slot. may fall out and fall to the bottom of the outer tank.

If the laundry falls to the bottom of the outer tub, it is not only very difficult to take it out, but it also rubs violently against the outer peripheral wall of the drum, causing damage to the fabric.
