As a result, the laundry may not only be tangled with each other as the fluid is mixed with the laundry during the washing, and the parts contacting the laundry may be formed to be soft, thereby improving washing performance as the contact with the laundry is increased.

Description

Washing ball for washing machine

The present invention relates to a laundry ball for a washing machine, and more particularly, to prevent the laundry from tangling with each other as the fluid is mixed with the laundry at the time of washing, and in contact with the laundry, the contact area with the laundry is formed to be soft. The present invention relates to a washing ball for a washing machine that can improve washing performance as it is increased.

Conventional washing machines have a substantially rectangular casing and a top cover coupled to the top of the casing. The top cover is provided with a door for accessing the laundry, and a water supply pipe for supplying the washing water is provided.

In the casing, a washing tank for accommodating laundry is provided, and a pulsator is installed in the lower region of the washing tank to form washing water in the washing tank by rotation. The shaft assembly is coupled to the bottom region of the washing tub and the pulsator along the shaft center of the washing tub and the pulsator. The shaft assembly is connected to the driving motor by a belt to transmit the driving force of the driving motor to the washing tub and the pulsator, respectively. In addition, a plurality of protrusions are formed on the inner wall of the washing tank.

According to this configuration, after the laundry is accommodated in the washing tank, an appropriate amount of detergent is put in accordance with the amount or type of laundry, and then washing is started by applying power, and an appropriate amount of washing water is supplied into the washing tank through the water supply pipe. When the supply of the washing water is completed into the washing tank, the pulsator rotates forward and backward to generate washing water flow in the washing tank.

By the way, in such a conventional washing machine, the laundry contained in the washing tank is caused to flow by the washing water generated by the rotation of the pulsator, the laundry is in contact with the inner wall surface of the washing tank while the washing flows along the washing water flow. In this way, when the laundry is in contact with the inner wall surface of the washing tank by the washing water flow, the area where the laundry is contacted by a plurality of protrusions protruding on the inner wall of the washing tank is widened, but the shape and quantity of the protrusions are damaged and the surface of the laundry It may be limited because it affects the flow of, there is a problem that the laundry during the washing flows along the water flow and tangled with each other.

Accordingly, an object of the present invention, not only to prevent the laundry from tangling with each other as the flow is mixed with the laundry during washing, but also to improve the washing performance as the contact area with the laundry is formed to be soft, so that the contact with the laundry is increased. It is to provide a laundry ball for a washing machine.

According to the present invention, in the washing ball for a washing machine, a spherical body formed of a rigid body; Laminated on the outer circumferential surface of the main body, it is achieved by a washing ball for a washing machine comprising a soft outer skin layer capable of elastic deformation.

Here, the outer skin layer is formed of polyethylene resin, it may be preferable that a plurality of protrusions protruding on the outer peripheral surface, the sum of the specific gravity of the body and the outer skin layer is preferably 20% to 80% of the specific gravity of the wash water. can do.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a longitudinal sectional view of a washing machine in which a washing ball for a washing machine according to the present invention is accommodated. As shown in this figure, a washing machine generally has a substantially rectangular casing 1 and a top cover 3 which is joined to the upper end of the casing 1.

The top cover 3 is provided with a door 4 that can be opened and closed for entering and exiting laundry. The water supply pipe 6 is provided in one area | region adjacent to the door 4 to supply wash water, and the water supply pipe 6 is normally paired so that hot water and cold water can be supplied.

A cylindrical outer tub 7 is coupled to the casing 1 by a plurality of suspension devices 5, and a cylindrical tub 9 for receiving laundry is rotatably installed in the outer tub 7. In the lower part of the washing tank 9, a disk-shaped pulsator 11 is formed to form washing water in the washing tank 9 as it rotates forward and backward. The center of the washing tank 9 and the pulsator 11 have an axis. Accordingly, the shaft assembly 13 is coupled. The shaft assembly 13 is connected to the driving motor 17 by the belt 15 to transmit the driving force of the driving motor 17 to the washing tank 9 and the pulsator 11, respectively. The laundry ball 19 is accommodated in the washing tank 9.

On the other hand, Figure 2 is a perspective view of a washing ball for a washing machine according to the present invention, Figure 3 is a cross-sectional view of the washing ball for a washing machine of FIG. As shown in these figures, the laundry ball 19 has a spherical body 20 having a space formed therein and an outer skin layer 23 laminated on the outer circumferential surface of the body 20. The main body 20 is made of plastic and has rigidity. In the outer skin layer 23 formed on the outer circumferential surface of the main body 20, a plurality of contact protrusions 21 are formed to protrude in order to widen the area in contact with the laundry. The outer layer 23 may be elastically deformed by a soft material such as polyester resin. The washing ball 19 has a predetermined weight, and when the washing ball 19 is not formed by the forward and reverse rotation of the pulsator 11 in the washing tank 9, approximately 50% of the diameter is the washing water surface. Locked in.

After the laundry is accommodated in the washing tank 9 according to the above configuration, the detergent and washing balls 19 are put in the appropriate amount according to the amount or type of the laundry, and then the washing machine is started by applying power. Washing water is supplied into the washing tank (9) through. After the supply of the washing water in the washing tank 9, the washing water flow occurs in the washing tank 9 by the forward and reverse rotation of the pulsator 11, and the laundry and the bowl 19 flow in the washing tank 9 by the washing water flow. Will be At this time, the laundry is in contact with the contact projections 21 formed on the outer layer 23 of the laundry ball 19 as well as the inner wall surface of the washing tank (9). The outer skin layer 23 of the laundry ball 19 in contact with the laundry is soft and is not slippery from the surface of the laundry, so that the contact with the laundry is large, and a predetermined elastic deformation is possible so that it is deformed in contact with the laundry. Restoration when separated from laundry results in the washing of the laundry as the contaminants attached to the surface of the laundry deviate from the surface of the laundry. Since the laundry ball 19 is mixed and flows between the laundry, the laundry balls 19 can be prevented from being tangled by the laundry during the washing.

Thus, by providing a washing body for washing machine having a spherical body formed of a rigid body, and a flexible outer skin layer laminated on the outer circumferential surface of the main body, the elastic deformation is possible, to prevent the laundry from tangling with each other as it flows when mixed with the laundry during washing In addition, the portion in contact with the laundry is formed in a soft, so as to increase the contact with the laundry can improve the washing performance.

As described above, according to the present invention, the laundry performance is not only prevented from being tangled with each other as the fluid is mixed with the laundry during the washing, and the contact area with the laundry is formed to be soft so that the contact with the laundry is increased. Washing ball for washing machine is provided to improve the.
