Problems solved by technology

[0002] At present, the bottom of the inner tub of a fully automatic washing machine is generally provided with a flange, and the position corresponding to the flange and the bottom of the inner tub is provided with a water outlet. Restriction, the size and number of water outlet holes that can be set are limited, so that the amount of washing water discharged from the water outlet holes is small and the water outlet capacity is poor
[0003] The washing machine controls the rotation of the inner tub, and through the rotation of the inner tub, the water discharged from the outlet hole is lifted along the inner wall of the outer tub and then enters the inner tub. Since the outlet hole is close to the middle of the bottom of the inner tub, the stroke is long, and the speed decays rapidly after being thrown out, so the lifting height is limited. , the improvement effect is poor
If you want to reach a higher height, you need to increase the output power of the motor, and the cost is high. Moreover, the laundry water discharged from the outlet hole generally fluctuates through the water-repelling blades or ribs, and the resistance is relatively large, so that the output power of the washing machine is large. easily damaged

Embodiment 1

[0034] Such as Figure 1-4 Shown is an inner tub of a washing machine. The washing machine includes an outer tub, an inner tub, and a driving device. The inner tub is arranged in the outer tub, and the driving device is arranged at the lower part of the outer tub. The output end of the driving device is connected to the inner tub to drive the inner tub to rotate. The inner tub includes The inner barrel bottom 100 and the inner barrel body, the inner barrel bottom 100 and the inner barrel body are detachably connected or integrally formed to form an inner barrel together, the inner barrel bottom 100 is provided with a drain port 101 communicating with the outer barrel, and the drain port 101 is provided with a water drain structure,

[0035] During washing, the driving device drives the inner tub to rotate, and the water-repellent structure lifts the washing water discharged from the drain port 101 upward along the inner wall of the outer tub and then falls into the inner tub t...

Embodiment 2

[0039] Such as Figure 1-4 As shown, this embodiment is a further limitation of Embodiment 1. The water-repellent structure includes at least one water-repellent rib 102 protruding from the outer wall of the inner bucket bottom 100, and one end of the water-repellent rib 102 is inserted into the drain 101 .

[0040] Taking one water-repelling rib as an example to explain, the water-repelling rib 102 divides the laundry water discharged from the drain port 101 into two strands, the left and the right, so that the water volume of each strand is further reduced, so that the inner tub can realize the opposite direction at a relatively low speed. The increase of washing water reduces the overheating damage of the motor and prolongs the service life of the washing machine.

[0041] Wherein, the number of water-repelling ribs 102 can be one or more. By setting multiple water-repelling ribs 102 to divide the laundry water into several strands, the quality of a single stream of water ...

Embodiment 3

[0050] Such as Figure 1-4 As shown, on the basis of Embodiment 1 and Embodiment 2, the water outlet 101 in this embodiment is set close to the edge of the inner tub bottom 100 . After the laundry water discharged from the water outlet 101 is directly lifted up along the wall of the outer tub, the stroke is short and the speed loss is small, and an upward water flow effect is generated when the inner tub is lifted and rotated.

[0051] Further, the inner tub bottom 100 is provided with a flange installation area 103 for installing a flange, and the drain port 101 is provided on the inner tub bottom 100 outside the flange installation area.

[0052] Preferably, the flange mounting area 103 is located at the bottom center of the inner barrel bottom 100 .

[0053] Since the flange is generally installed at the center of the inner tub bottom 100 and is far away from the edge of the inner tub bottom 100, the drain outlet 101 is arranged on the inner tub bottom 100 in an area other...

Abstract

The invention belongs to the field of washing machines, and in particular relates to an inner tub of a washing machine. The washing machine includes an outer tub, an inner tub and a driving device. The output end of the driving device is connected to the inner tub to drive the inner tub to rotate. The inner tub includes the bottom of the inner tub. The bottom of the inner barrel is provided with a drain connected to the outer barrel, and the drain is provided with a water-draining structure. The beneficial effect of the present invention is that a drain connected to the outer barrel is provided on the bottom of the inner barrel, and a dial is provided on the drain. Water structure, when the laundry water is discharged from the drain, the discharged laundry water is directly lifted up along the wall of the outer barrel through the water-repellent structure and then falls into the inner barrel for washing clothes, the stroke is shorter and the lifting effect is better; the water-repellent structure It is a water-repelling rib, and one end of the water-repelling rib is inserted into the drain, and the laundry water discharged from the drain is divided into two strands, the left and the right, so that the water volume of each strand is reduced, so that the inner bucket can realize the washing water at a relatively small speed. Improve, reduce motor overheating damage, prolong the service life of the washing machine.
