Problems solved by technology

However, the existing drum washing machine has the following disadvantages: the drum washing machine only relies on lifting and beating the clothes for washing, and there is no rubbing effect on the clothes, which makes the washing efficiency of the clothes poor
However, the problem with this setting is that during the relative rotation between the large-size pulsator and the inner tube, the clothes are easily caught in the gap between the inner tube and the pulsator, causing wrinkles and damage to the clothes, and even damage to the pulsator in severe cases. wheel

Embodiment 1

[0034] Such as figure 1 The drum washing machine shown includes an inner tub 1 and a pulsator 2 arranged at the bottom of the inner tub 1, and the inner tub 1 and the pulsator 2 can rotate at a differential speed or at a constant speed. In order to ensure the unimpeded relative rotation of the pulsator 2 and the inner cylinder 1, a certain gap will be reserved at the edge of the pulsator 2 and the side wall of the inner cylinder 1 when the pulsator 2 is installed. However, during the laundry washing process, the clothes are easily caught in the gap and affect the washing effect. The present invention uses a blocking structure 30 on the inner wall of the inner tube 1 close to the outer periphery of the pulsator 2 to prevent clothes from being caught between the pulsator 2 and the inner tube. The gap between 1.

[0035] Such as figure 2 As shown, the blocking structure 30 includes a first blocking portion 31 and a second blocking portion 32. The first blocking portion 31 is perpen...

Embodiment 2

[0041] Such as image 3 with Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the first blocking portion 31 is located between the bottom of the inner cylinder 1 and the edge of the pulsator 2, and the second blocking portion 32 is a part of the first blocking portion 31. The end portion is formed by bending in a direction away from the bottom of the inner cylinder 1, and it is preferable that the second blocking portion 32 and the first blocking portion 31 are arranged in an L shape. The second blocking portion 32 is used to block the gap between the pulsator 2 and the first blocking portion 31.

[0042] The pulsator 2 is also provided with a mating part 4 staggered with the second blocking part 32. The mating part 4 is perpendicular to the outer peripheral edge of the pulsator 2 and extends in the direction of the first blocking part 31, that is, toward the inner side. The barrel 1 extends in the direction of the bottom, an...

Embodiment 3

[0046] Such as Figure 5 with Image 6 As shown, the difference between this embodiment and Embodiment 1 is that there is no connecting portion 33 in this embodiment, and a buffer surface 34 is provided on the side of the first blocking portion 31 away from the bottom of the inner cylinder. The angle between the inner walls of 1 is an acute angle. By providing a buffer surface 34 on the first blocking portion 31, the impact force of the water flow and clothes on the first blocking portion 31 during the operation of the washing machine can be effectively buffered, and the damage of the first blocking portion 31 due to the impact force of the water flow and the clothes can be reduced. Happening.

Abstract

The invention belongs to the field of washing machines and particularly discloses a roller washing machine. The roller washing machine comprises an inner cylinder and an impeller arranged at the bottom of the inner cylinder, wherein a stop structure is arranged on the inner wall, close to the periphery edge of the impeller, of the inner cylinder, the stop structure prevents clothes from getting stuck in a gap between the periphery edge of the impeller and the inner cylinder, and therefore the situation that the clothes get stuck in the gap between the impeller and the inner cylinder in the washing process, consequently the clothes generate wrinkles or are damaged, or even the impeller is damaged is avoided.

Description

Technical field [0001] The invention belongs to the field of washing machines, and specifically relates to a drum washing machine. Background technique [0002] Existing drum washing machines generally have an outer drum inside the washing machine. An inner drum driven by a motor is installed in the outer drum. After clothes are placed in the inner drum, a small amount of washing water flows into the outer drum to soak the clothes, so that the clothes are The washing water containing detergent is fully mixed; the motor is then used to drive the inner tube to rotate, the lifting ribs and other structures in the inner tube are used to lift and beat the clothes, and the clothes are washed by the force of the beat. However, the existing drum washing machine has the following shortcomings: the drum washing machine only relies on washing the clothes after being lifted, and does not have a rubbing effect on the clothes, resulting in poor washing efficiency of the clothes. The existing ...
