Description

reciprocating washing machine

The present invention relates to a washing device, in particular to a reciprocating washing machine, which uses a driving motor provided in the washing drum to drive a guide rod and a reciprocating pressure plate to move, and the reciprocating pressure plate reciprocates in the washing drum to Disturb water and clothes to achieve the function of cleaning clothes.

According to the conventional washing machine, it is divided into upright type and drum type. Taking the upright type as an example, its placement direction is perpendicular to the ground and the opening faces upward. The method of use is to first put the clothes to be washed through the upper opening and put them into the washing machine. After adding the appropriate amount of water and detergent, use the drum in the outer drum to perform washing, cleaning and dehydration procedures. During the washing and cleaning process, the drum is allowed to rotate back and forth quickly left and right to create a rotating vortex in the water inside. , to impart the impact of water flow to the clothes to achieve the effect of washing the clothes. Furthermore, during the dehydration process, the drum is allowed to rotate freely at high speed, and the centrifugal force generated by the rotation separates the water from the clothes to achieve dehydration. Effect.

In addition, taking the drum type as an example, the placement direction is tilted to the ground with the opening facing forward. The method of use is to put the clothes to be washed through the opening in the front, put in an appropriate amount of water and detergent, and use it to set it outside. The drum in the center of the drum rotates freely to perform procedures such as washing and dehydrating clothes. During the washing process, the drum is rotated slowly and the clothes are tumbled from the bottom of the drum to the top of the drum, and then the clothes are moved by gravity (gravity). It rolls from top to bottom to impart impact force to the clothes to achieve the effect of washing the clothes.

However, the upright type consumes a considerable amount of water when used. When the drum rotates and the water generates a whirlpool, the clothes are often twisted into a ball, so the overall washing process is longer. Although the drum type is compared with the upright type, The amount of water used is less, but because the space in which the clothes can move is narrow, the tumbling of the clothes is restricted, so the cleaning power of the clothes is relatively poor, and it takes a longer time to clean the clothes.

In view of this, in order to overcome the shortcomings of the conventional solution, the inventor developed an improved solution for the reciprocating washing machine through active thinking, prototype testing and improvement, which can completely solve or effectively improve many deficiencies of the conventional solution.

The invention discloses a reciprocating washing machine, which includes a washing machine casing; a washing drum assembly unit; the washing drum assembly unit includes an outer washing drum, an inner washing drum and a dehydration motor; the outer drum and the washing drum are The inner drum is installed obliquely inside the casing of the washing machine. One end of the inner drum is fixed with a pulley. The pulley is linked to the dehydration motor through a belt. The dehydration motor can drive the belt to rotate, so that the belt drives the dehydration motor. The inner drum of the washing machine rotates in the outer drum of the washing machine; a reciprocating operation unit is provided in the casing of the washing machine. The reciprocating operation unit includes a driving motor, a guide rod and a reciprocating pressure plate. The driving motor is The guide rod is disposed at one end of the outer drum of the washing machine. The guide rod is passed through the center of the outer drum of the washing machine and the inner drum of the washing machine at the same time. It has a first end and a second end that are oppositely arranged. The driving motor is engaged with the The first end and the reciprocating pressure plate are swingably connected to the second end, so that the guide rod can be driven by the driving motor to link the reciprocating pressure plate to move back and forth in the center of the washing drum.

With the above structure, the guide rod of the present invention can be driven by the driving motor, and can link the reciprocating pressure plate to move back and forth in the center of the inner drum of the washing machine. The composite pressure plate can rotate and swing relative to the guide rod to truly disturb and squeeze the clothes and water, thereby reducing the water consumption and time spent in washing, and improving the efficiency of washing clothes.
