Description

Washing water circulation of inner-tub-turning-type washing machine

The present invention relates to a loop washing machine, and more particularly, a plurality of water wings are radially installed on the outer circumferential surface of a washing tank rotating during washing, and the washing water generated from the water wing on the inner circumferential surface of the storage tank is radially installed. The present invention relates to a washing water circulation type loop washer that improves the washing power and the degree of rinsing by using a water jet and a drop of washing water by the water wing and the spraying machine during the washing.

In general, the washing machine is to wash the laundry automatically through water supply, drainage, rinsing, and dehydration. Most commonly, a washing machine itself includes a pulsator-type washing machine in which a pulsator installed at the bottom of the washing tank rotates. There are various types of washing machines, such as type washing machines and outgoing washing machines where the pulsator and the washing tank rotate in opposite directions.

As shown in FIG. 1, the outrunner type washing machine 101 includes a cabinet 103 that largely forms an external body, and a storage tank 105 installed inside the cabinet 103 to accommodate a predetermined amount of washing liquid. A plurality of washing liquid distribution holes 107 are formed on the side, and a washing tank 109 installed inside the water storage tank 105, a pulsator 111 installed on the bottom of the washing tank 109 to generate water flow, It consists of a drive unit 113 for generating a rotational force of the pulsator 111.

At this time, the lid 117 is rotatably connected to one side of the opening of the upper panel 115 of the cabinet 103 by the hinge 119, and the operation of the washing machine 101 is controlled inside the upper panel 115. The control unit 121 is built in. In addition, a drain pipe 123 for discharging turbid water after washing is connected to one lower end side of the reservoir 105. And a detergent tank 127 connected to the water supply hose 125 is installed on one side of the upper end of the reservoir 105.

Here, the conventional loop washing machine 101 transmits the rotational force of the driving motor 135 to the pulsator 111 and the washing tank 109 by the rotation shaft bundle 133 of the driving unit 113 and the motor pulley 137. The rotational force is transmitted through the transmission belt 141 while having a constant reduction ratio according to the diameter difference of the rotation shaft pulley 139.

As described above, the rotary shaft bundle 133 mounted at the bottom center of the water storage tank 105 to transmit the rotational driving force from the driving motor 135 to the pulsator 111 and the washing tank 109 has the rotational force transmitted from the rotation shaft pulley 139. In the case of the conventional outgoing washing machine 101 to have a function of rotating the pulsator 111 and the washing tank 109 in the opposite direction through the decelerating speed at a constant rate and at the same time as the reduced driving speed, as shown in more detail in FIG. 2. It has the same structure.

As shown in FIG. 2, the rotating shaft bundle 133 may have a two-axis structure in which the rotating shaft is divided into the inside and the outside so that the pulsator 111 and the washing tank 109 can be turned in opposite directions. have. Here, the biaxial structure is, as can be seen in Figure 1 of the inner dehydration shaft 145 attached to the center of the lower surface of the washing tank 109 and the inner side attached to the center of the pulsator 111 inside the washing tank 109 The laundry shaft 147 is referred to.

In addition, as another feature, a reduction gear including a washing shaft 147 as a sun gear, a dehydrating shaft 145 as a ring gear, and a planetary gear 151 mounted between the washing shaft 147 and the dewatering shaft 145. The portion 149 decelerates the rotational driving force transmitted from the rotation shaft pulley 139.

Therefore, the loop washing machine 101 configured as described above basically performs the washing operation as follows. First, the laundry is put into the washing tank 109, and then a proper amount of detergent is put into the detergent container 127, and a water supply hose is provided. When the water supply source such as the faucet connected to the 125 is opened, the water supplied into the detergent container 127 via the water supply valve 131 becomes a washing liquid mixed with the detergent and is filled to the inside of the washing tank 109 to a certain height.

Then, the rotational force generated by the driving motor 135 by the user's operation is primarily at a reduction ratio according to the diameter difference between the pulleys 137 and 139 in the process of being transmitted to the motor pulley 137, the transmission belt 141, and the rotation shaft pulley 139. It is transmitted to the washing shaft 147 of the rotating shaft bundle 133 while decelerating.

At this time, in the normal operation state in which the pull switch 155 does not operate, since the spring clutch 153 is in an open state, the rotational force of the washing shaft 147 is not directly transmitted to the dehydration shaft 145, and the reduction gear unit 149 Since the dehydration shaft 145 is transmitted to the dehydration shaft 145 in a decelerated state at a predetermined rate through), the dehydration shaft 145 has a rotational direction opposite to the rotational direction of the washing shaft 147 at the same time as the driving force increases.

In this manner, when the rotation of the pulsator 111 and the washing tank 109 is started and the power is supplied at a predetermined time interval, the pulsator 111 and the washing tank 109 are repeatedly rotated in the opposite directions with the proper rotational force, and the inside of the washing tank 109 Water is generated in the laundry to wash the laundry. After rinsing and dehydration after the washing process, all washing processes are finished.

By the way, as described above, the existing loop washing machine or pulsator type washing machine equipped with the pulsator simply uses the water flow by the pulsator or the water flow due to the reverse rotation of the washing tank, thereby reducing damage such as the cloth of the laundry, but strong washing power. There is a problem that can not be obtained.

On the other hand, a technique for increasing the washing power in a pulsator type washing machine has been conventionally developed. As the washing force increasing technology of such a pulsator type washing machine, a double pulsator type washing machine of Korean Patent Application Publication No. 89-17640 is known.

In this double pulsator type washing machine, as shown in FIG. 3, a rod-type main pulsator 211 is installed at the center of the bottom of the washing tank 205, and the upper end of the rod 212 of the main pulsator 211. It has a configuration in which a disk-shaped auxiliary pulsator 250 having a hub 251 to be attached to and detached from it.

Accordingly, by using the rotational water flow according to the rotation of the main pulsator 211 at the bottom of the washing tank 204 during the washing and the rotational water flow according to the rotation of the auxiliary pulsator 250 in the upper washing tank 204, It was possible to increase the laundry power of the laundry through.

However, such a double pulsator type washing machine must separate the auxiliary pulsator 250 from the main pulsator 211 to open the input of the washing tank 204 in order to inject laundry into the washing tank 204 during washing. In addition, there is a problem in that the auxiliary pulsator 250 must be coupled to the main pulsator 211 even after the laundry is put in.

Accordingly, the present invention has been made in view of the above problems, by forming a water flow generating structure between the washing tank and the storage tank separately from the rotating pulsator, the water flow of washing water flowing into the washing tank during washing and the drop of washing water The purpose of the present invention is to provide a washing water circulation loop washing machine that can increase washing power and rinsing degree as well as reduce user's hassle.
