Embodiment 1

[0020] Such as figure 2 , 3 , 4, in the buoyancy chamber 12 of inner tub 1 bottom, the present invention is provided with a circle isolation ring 10 around the inner concave gear 4, and isolation rib 11 is set in isolation ring 10, isolation rib 11 and isolation ring 10 and inner tub are One-piece structure, with a permeable hole 13 running through the bottom of the inner tub 2 between the two, and the permeable hole 13 is used for the exchange and circulation of washing water during laundry. The isolation rib 11 forms a closed chamber around the concave gear 4, and the closed chamber forms a sealed inner buoyancy chamber after the inner bucket 1 is connected with the pulsator drive shaft 3, together with the buoyancy chamber 12 formed by the inner bucket wall and the insulating ring, the inner bucket is aligned. Floating up produces buoyancy. The inner buoyancy chamber will form a sealed chamber after the washing machine is filled with water. The sealed chamber can prevent...

Embodiment 2

[0022] On the basis of Embodiment 1, the isolation rib and the concave gear are integrated, and an internal buoyancy chamber is formed at the bottom of the inner bucket when the concave gear is installed. In this way, different isolation ribs can be configured according to different concave gears, and there are many options for installation with the inner tub, and the manufacturing process of the existing washing machine inner tub can be reduced.

Embodiment 3

[0024] On the basis of the foregoing embodiments, a height-adjustable scheme is adopted for the isolation rib, and various pipes of different lengths are equipped according to the diameter and shape of the isolation rib. - That is, use the diameter difference of the pipe or connect the sleeve to connect the two together, clamping - use the fixed buckle to connect the two together, the above method can adjust the height of the isolation rib, so that the washing machine after setting can be adjusted Sex, improve product adaptability and reduce substandard products. The specific connection methods are not limited to the above three, as long as the sealing of the connection can be ensured.

Abstract

The invention discloses a protection structure for a small-sized buoyancy washing machine, and relates to the field of washing machines. The buoyancy chamber is provided with an inner buoyancy chamber, and the side of the bearing seat in contact with the outer tub is provided with a protective cover connected to the pulsator drive shaft. The joint of the pulsator drive shaft extends to the inner buoyancy chamber. The present invention arranges isolation ribs around the inner concave gear of the clutch device of the washing machine, and utilizes the characteristic that the sealing cavity of the inner buoyancy chamber is higher than the sealing cavity of the buoyancy chamber formed by the side wall of the inner barrel, so that the connection between the protective sleeve and the drive shaft of the pulsator is located above the water level , to prevent the washing water from entering the protective sleeve from the joint to affect the sealing effect and reduce the life of the skeleton oil seal. At the same time, it also protects the pulsator drive shaft between the top of the protective sleeve and the bottom of the inner barrel from adhering impurities. This scheme has a simple structure and can prolong The service life of the buoyancy washing machine is improved, and the occurrence of failures is reduced.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a protection structure for a pulsator drive shaft between an outer tub sealing part and a clutch of a small / micro buoyancy pulsator washing machine. Background technique [0002] There is a kind of washing machine in the prior art that is a buoyancy washing machine. When this type of washing machine works, the lifting of the inner tub is controlled by the buoyancy of the water, so the washing capacity is small, and it is only applicable to some small / miniature washing machines. The structure of the buoyancy washing machine is as follows: There is a buoyancy chamber at the bottom of the inner barrel of the buoyancy washing machine, and the middle of the bottom of the inner barrel is sleeved on the drive shaft of the pulsator through a closed bearing. The clutch device of the buoyancy washing machine is driven by a concave gear installed on the periphery of the sealed bearing and ins...
