Problems solved by technology

In addition, the abnormal vibration caused by the laundry (also referred to as load) placed in the washing and dehydrating tank is biased to one side is particularly dangerous when it is close to the target high-speed dehydration speed, and may cause damage to the washing machine.

Embodiment 1

[0153] Next, embodiments of the washing machine of the present invention will be described based on the drawings. In the washing machine SW of the present invention, the inside of the housing 1 with the laundry inlet 2 formed on the top surface is passed through the hanger 5 (in the figure 1 One can be seen in the front and the rear, but in fact there are two in the front and rear respectively) The outer tank 4 made of synthetic resin with a bottomed cylinder is suspended and supported freely, and thereby the vibration of the outer tank 4 is prevented from being transmitted to the The housing 1, wherein the hanger 5 is composed of a hanging rod 5A and a vibration damping mechanism 5B including a spring. The laundry inlet 2 can be freely opened and closed by the upper cover 3A that can be folded in half when standing up. Inside the outer tank 4, a washing and dewatering tank 6 having a plurality of water passage holes 7 on the peripheral wall is rotatably supported around the ...

Abstract

The invention provides a washing machine, wherein a washing dehydration tank and a pulsator integrally formed in an outer groove is rotated at a high speed so as to perform the dehydration of laundry. Meanwhile, a mechanism is provided to restrain the vibration of the washing dehydration tank via the electrical control. When the outer groove is made of synthetic resin, the intrinsic value of the outer groove (inherent resonance point) varies with the temperature. When the temperature of the outer groove rises, the rotation speed of the washing dehydration tank is lowered so as to be away fromthe inherent value of the outer groove and prevent the abnormal vibration. In addition, the temperature of the outer groove can also be directly or indirectly determined. If the temperature rises, the dehydration speed is lowered. If the temperature decreases, the dehydration speed is increased. Meanwhile, by utilizing a washing machine with drying function, wherein the circulation of the washingdehydration tank is realized by the heating of a heater, if the temperature at the outlet of the heater rises, the dehydration speed is lowered. If the temperature decreases, the dehydration speed isimproved.

Description

technical field [0001] The present invention relates to a washing machine, in particular to a vertical washing machine having a washing and dehydrating tank with an open top surface which can rotate around a vertical or inclined axis. Background technique [0002] In a typical vertical fully automatic washing machine, a bottomed cylindrical outer tank is suspended and supported by a suspension rod for absorbing vibrations. Inside the outer tank, there is also a bottomed cylindrical outer tank with a surrounding opening. A washing and dewatering tank with a plurality of dehydration holes, and the washing and dewatering tank can freely rotate around a vertical or inclined axis, and at the inner bottom of the outer tank, a pulsator (stirring blade) for stirring (such as Refer to Patent Document 1, Patent Document 4, etc.). [0003] In such a washing machine, the laundry is dehydrated by rotating the washing and dehydrating tank integrally with the pulsator at a high speed. Vi...
