Description

Balancer assembly of washing machine

The present invention relates to a washing machine, and more particularly, to a balancer of a washing machine having a laundry leaving prevention jaw for preventing laundry from being damaged by being separated from the outside of the dehydration tank during washing or dehydration.

In general, a washing machine as shown in FIG. 1 is a device for washing laundry such as clothes or duvets using mechanical force. Such a washing machine performs washing by removing foreign substances or contaminants adsorbed on the laundry by the friction and impact of the water flow by the action of an agitator such as a pulsator in addition to the emulsifying action of the detergent. Recently, a fully automatic washing machine has been provided which can be completed not only by washing but also by rinsing and dehydration through a series of processes.

The configuration of the automatic washing machine will be briefly described with reference to FIGS. 2 and 3 as follows.

First, the washing tank 20 is suspended by the suspension device 30 inside the case 10, and the dehydrating tank 40 and the pulsator 50 are provided inside the washing tank 20. In addition, a clutch assembly 60 for driving the dehydration tank 40 and the pulsator 50 is installed at the lower side of the washing tank 20, and the clutch assembly 60 is driven through a belt 70. 80).

In this way, as the clutch assembly 60 driven by the motor 80 stirs the pulsator 50 in the forward and reverse directions and stirs the flow to the water stream, the emulsification of the detergent and the physical action of the wash water. The laundry works together with the laundry.

When the laundry is dewatered, moisture contained in the laundry is separated from the laundry by the clutch assembly 80 rotating the pulsator 50 and the dehydration tank 40 together in one direction at a high speed.

At this time, the balancer assembly 90 is installed above the dehydration tank 40 so that the dehydration tank 40 can be smoothly rotated. The balancer assembly 90 is composed of an upper balancer 91, a lower balancer 92 and a laundry separation prevention 93. The upper and lower balancers 91 and 92 are filled with a viscous fluid or a plurality of balls (not shown) are incorporated therein. Therefore, the dehydration tank 40 rotates smoothly by the flow of the inertia and the ball by the viscosity of the fluid.

The laundry leaving prevention jaw 93 extends upward along the inner circumference of the upper balancer 91. The departure prevention jaw 93 is to prevent the laundry from being departed from the dehydration tank to enter between the dehydration tank 40 and the washing tank 20, especially when washing a large amount of laundry.

For reference, reference numeral 41 in the drawing is a debris filter net for filtering foreign matters such as lint in the wash water during washing, 42 is a wash water guide for guiding the wash water to the foreign matter filter net, 21 is a washing tank cover to be. In addition, 11 and 12 are a water supply part and a drain part for supplying and discharging wash water, respectively.

By the way, in the past, since the laundry leaving prevention jaw 93 extended from the upper balancer 91 vertically extended upward, the laundry could be prevented from entering between the dehydration tank 40 and the washing tank 20. However, the laundry placed on the upper side by the centrifugal force due to the rotation of the dehydration tank 40 was not prevented from being separated to the upper side of the washing tank cover 21. Therefore, when laundry or dehydration, the laundry is separated to the upper side of the washing tank cover 21 and rubbing with the washing tank cover 21 has a disadvantage that the laundry and the washing tank cover 21 are damaged.

In addition, the conventional balancer assembly 90 as described above, when loaded for transportation and storage, interferes with the bottom of another balancer assembly 90 'on which the laundry departure prevention jaw 93 is loaded thereon. Accordingly, as shown in FIG. 4, the balancer assembly 90 ′ loaded on the upper side is placed on the upper end of the laundry separation prevention 93 of the lower balancer assembly 90. Therefore, when loading a large amount of balancer assembly there is a fear that the laundry separation prevention jaw (93, 93 ') is damaged by the loading load. Accordingly, the balancer assembly has a disadvantage in that it takes up a lot of loading area because it can only be loaded by a small amount during loading.

The present invention has been made in order to solve the above disadvantages, to provide a balancer assembly of the washing machine to prevent the laundry is separated from the outside of the dehydration tank when the washing or dehydration to be rubbed or damaged by the cover of the washing tank. There is a purpose.

In addition, another object of the present invention is to provide a balancer assembly of a washing machine that can prevent the laundry departure prevention jaw from being broken due to its loading weight during storage or transportation.
