Technical Field

The utility model relates to the technical field of household or commercial pulsator washing machines, in particular to an anti-falling structure applied to a spin dryer tube.

Background

A washing machine is a cleaning appliance that washes laundry using electric power to generate mechanical action.

The pulsator washing machine is another type of washing machine, in which a pulsator is driven by a motor to rotate, and clothes continuously roll up and down along with water. The washing clothes are in a single barrel, a sleeve barrel and a double barrel. The washing machine has the advantages of simple structure, convenient maintenance and high washing rate, but has high wear rate on clothes and much water consumption. With the development of technology, a new water flow washing machine controlled by a computer is developed nowadays, and a large impeller, a concave impeller and the like are adopted. Has the advantages of small winding of clothes, uniform washing and low clothes loss rate.

Referring to patent document 202222211706.5, the utility model discloses a washing machine with a clutch switching mechanism, which comprises a shell, a motor, a wave disc and a spin-drying barrel, wherein the motor, the wave disc and the spin-drying barrel are arranged in the shell, the wave disc is in transmission fit with an output shaft of the motor through a transmission shaft sleeve, and the wave disc is in engageable connection with the spin-drying barrel through a lifting transmission mechanism; a gear mechanism is arranged between the spin dryer tube and the wave disc, wherein the gear mechanism is provided with a tooth-shaped meshing section and a non-tooth-shaped separation section; when the wave disc is relatively aligned with the toothed engagement section, the wave disc is in dynamic engagement with the gear mechanism; when the wave disc is relatively aligned with the non-tooth-shaped stripping section, the wave disc is separated from the gear mechanism in power.

As described above, the lifting transmission mechanism is adopted, so that the transmission function and the clutch switching function between the spin dryer tube and the wave disc can be realized, and the maintaining function of the position and the functional state can be realized. On one hand, the cost of parts can be effectively reduced, and on the other hand, the structure and the production and assembly process are simplified, so that the whole machine is smaller; and the switching function between washing and spin-drying can be automatically realized by matching with a program, and meanwhile, a special person is not required to take and put clothes, so that the effect of washing and spin-drying in one step is achieved.

However, products of the type described above are sometimes in fact subject to some drawbacks, such as: in the washing process, the spin dryer tube is required to be continuously separated from the wave disc and is in an unconstrained state. However, as the wave disc stirs water, the stirring force indirectly acts on the spin-drying barrel through the water, so that the position of the spin-drying barrel is fluctuant, the wave disc is easy to hit, the rotation of the wave disc is influenced, and the spin-drying barrel and the wave disc are seriously damaged.
