Problems solved by technology

[0005] The purpose of the present invention is to solve the above-mentioned problems existing in the existing washing machine. The strong water flow generated when the rotating drum rotates at a high speed washes away the foreign matter and dirt such as washing powder slag attached to the outer cylinder wall of the rotating drum, thereby maintaining the outer peripheral wall. in a clean state

Embodiment Construction

[0026] An embodiment of the present invention will be described below with reference to the accompanying drawings. In addition, it should be pointed out that such embodiments do not limit the present invention.

[0027] Such as figure 2 As shown in , the rotary drum 1 is made into a cylindrical shape with a bottom, and many water holes 2 are provided on the entire outer cylinder surface, and the rotary drum 1 is set in a water tub 3 in a rotatable manner. The rotation center of the rotating drum 1 is provided with a rotating shaft (rotation center shaft) 4 in a substantially inclined direction, and the axis direction of the rotating drum 1 is installed so as to be inclined downward from the front side to the back side. The rotating shaft 4 is connected with the motor 5 installed on the back side of the water bucket 3, and the motor 5 drives the rotary drum 1 to rotate forward and reversely. A plurality of protruding plates 6 are provided on the inner wall surface of the rot...

Abstract

The present invention is a washing machine which performs washing, rinsing and dehydration in a rotating drum whose rotating shaft is approximately in a horizontal direction or an inclined direction, and uses the strong water flow generated when the rotating drum rotates at a high speed to remove foreign matter attached to the outer cylinder wall of the rotating drum. And the dirt is washed away, and the outer peripheral wall is kept in a clean state. Among them, the water tub is elastically supported in the body of the washing machine, and the water tub is provided with a rotating drum whose rotation center axis is in a horizontal direction or an inclined direction, and the rotating drum is driven by a motor, and a frequency converter provided with a switching element supplies power to the motor. Power, the control device controls the switching elements in the frequency converter, thereby controlling the drive of the motor. The control device controls the rotational speed of the rotary drum to a first predetermined rotational speed that is higher than the rotational speed at which the laundry sticks to the rotary drum and lower than the steady-state rotational speed of dehydration in the state where water is accumulated in the tub, and executes the washing process of the rotary drum .

Description

technical field [0001] The present invention relates to a washing machine which performs washing, rinsing and dehydration operations in a rotating drum whose rotation central axis is substantially set in a horizontal direction or an inclined direction. Background technique [0002] In the existing washing machine, the laundry is contained in a rotatable rotary drum, which is arranged inside the tub, and the center of the rotary drum is provided with a horizontal axis. The front side of the bucket is provided with a clothes inlet and outlet which can be opened and closed by the machine door, and laundry can be thrown into the rotary drum through the clothes inlet and outlet. Various operations such as washing, rinsing, and spinning are performed by controlling the filling and draining of water into the tub, and the rotation of the rotary drum. In addition, by forming a circulation blowing passage that exhausts the air in the tub, passes through the dehumidification unit and ...
