Description

A pulsator structure and washing machine

technical field

The invention relates to a washing machine in the field of washing equipment, in particular to a pulsator structure of the washing machine, and also to a multifunctional washing machine equipped with the pulsator structure.

Background technique

Existing pulsator type washing machine, as shown in Figure 1, pulsator washing machine has a casing that constitutes its outer contour, an outer tub 200 is installed inside the casing, an inner tub 100 is set inside the outer tub 200, and a pulsator structure 300 is arranged at the bottom of the inner tub 100 ; The upper part of the shell is provided with a reversible and open upper cover to put clothes into the inner tub 100 from the opened upper cover for washing. The housing is also provided with a motor 400. The motor 400 is generally installed below the outer tub 200. The motor shaft 3 of the motor 400 extends upwards and passes through the bottom of the outer tub 200 and the bottom of the inner tub 100 in turn, so that the motor shaft 3 and the inner tub The pulsator structure 300 in 100 is meshed and fixed, so that the pulsator structure 300 is driven to rotate by the motor 400 to agitate the water and clothes in the inner tub 100 . At the same time, in order to enhance the agitation of the water flow by the pulsator structure 300 , generally a plurality of upwardly protruding ribs 18 are provided on the upper surface of the pulsator structure 300 to enhance the stirring of the water flow during the rotation of the pulsator structure 300 . In addition, in order to strengthen the strength of the pulsator structure 300, generally a plurality of reinforcing ribs 15 protruding downwards are provided on the lower side of the pulsator structure 300 to improve the overall support strength and torsional strength of the pulsator structure.

The working principle of the pulsator washing machine with the above structure for washing clothes is as follows: rely on the pulsator structure installed at the bottom of the inner tub to rotate positively and negatively, so as to drive the clothes in the inner tub to turn up and down, left and right, so that the clothes between the clothes, the clothes and the barrel wall In between, gently rubbing in the water continuously; and putting detergent in the water, so as to realize the purpose of removing stains attached to the clothes and cleaning the clothes under the action of the detergent. Therefore, the pulsator washing machine relies on the pulsator to drive the water flow to impact the clothes, so that the clothes will be rubbed to remove stains, so as to achieve the purpose of washing the clothes.

However, the pulsator washing machine with the above structure will cause the following problems in the process of washing the clothes:

1. The pulsator is in direct contact with the clothes in the inner tub. In particular, since the upper surface of the pulsator structure has ribs protruding upwards to varying degrees, the clothes will be in contact with the rotating ribs and thus be damaged by the ribs.

2. The stirring water flow is generated by the rotation of the pulsator in the inner bucket, and the stirring water flow will oscillate back and forth, causing the clothes to be entangled with each other and knotted, which will cause the clothes to deform.

In particular, when the pulsator washing machine washes some wool, cashmere, silk and other clothes, the phenomenon of clothing entanglement is more obvious, and the wear is more serious, so that the user cannot use the pulsator washing machine to wash the above wool, cashmere, silk, etc. Wash clothes made of silk and other materials.
