Problems solved by technology

[0011] Therefore, like the above-mentioned conventional installation method, when the mounting feet 63 are arranged at equal intervals along the circumferential direction, it can be known from the relationship between the number of pole teeth and the number of mounting feet 63 that all positions of the vibration peak value of the stator 60 correspond to all positions of the mounting feet 63. Consistent, the installation device transmits its vibration to the water tank 52, which tends to increase vibration, noise

Abstract

The invention provides a drum type washing machine which comprises a rotary drum for receiving laundry, a water tank containing the rotary drum, a motor for driving the rotary drum fixed to the back of the water tank, and a rotating shaft for transmitting rotation of the motor to the rotary drum. The motor has a stator molded of resin material and fixed to the back of the water tank at a pluralityof points by means of a plurality of fixing devices formed integrally by resin mold to extend outward from the outer circumference, and a rotor connected to the rotating shaft and supported rotatablyon the back portion of the water tank. Assuming the number of teeth extending radially from the stator is 6N (N is a natural number) and the number of the fixing devices is M, 2N and M are relativelyprime and the number of poles of the motor is 10N.

Description

technical field [0001] The present invention relates to a drum type washing machine, which is driven by a motor to rotate the rotating drum to wash the laundry accommodated in the rotating drum. The direction of the rotation axis of the drum is horizontal from the front side of the opening toward the back side of the bottom, or is installed in the water tank so as to be inclined downward with respect to the horizontal direction. Background technique [0002] Figure 9 It is a cross-sectional view showing a front-loading washing machine using a conventional inner rotor motor, Figure 10 It is a cross-sectional view showing a front-loading washing machine using the same outer rotor type motor, Figure 11 It is the rear view of the electric motor of the front-loading washing machine which adopted the outer rotor type electric motor similarly. [0003] like Figure 9 , Figure 10 As shown, this drum type washing machine is provided with a rotating drum 54 formed with a plural...
