Description

Technical Field

[0001] The present invention relates to a washing machine, in particular to a reciprocating washing machine, which utilizes a driving motor provided in a washing drum to drive a guide rod and a reciprocating pressure plate to move back and forth in the washing drum to disturb water and clothes to achieve the function of washing clothes. Background Art

[0002] Commonly used washing machines are divided into upright type and drum type. Taking the upright type as an example, its placement direction is perpendicular to the ground with the opening facing upward. The method of use is to first put the clothes to be washed through the opening on the top, and then add a proper amount of water and detergent, and then use the drum in the outer drum to perform the washing, cleaning and dehydration procedures. During the washing and cleaning process, the drum is rotated back and forth quickly to the left and right, so that the water inside generates a rotating vortex to give the clothes an impact force of the water flow to achieve the effect of washing the clothes. Furthermore, during the dehydration process, the drum is rotated freely at a high speed, and the centrifugal force generated by the rotation separates the water from the clothes to achieve the dehydration effect.

[0003] In addition, taking the drum type as an example, it is placed in an inclined direction on the ground with the opening facing forward. The way of use is to put the clothes to be washed from the front opening, and add an appropriate amount of water and detergent, and then use the drum set in the center of the outer drum to rotate freely to perform procedures such as washing and dehydrating the clothes. During the washing process, the drum is rotated slowly, and the clothes are rolled from the bottom of the drum to the top of the drum, and then gravity is used to roll the clothes from the top to the bottom, so as to give the clothes a collision force and achieve the effect of washing the clothes.

[0004] However, the upright type requires a considerable amount of water when used. When the drum rotates to generate a rotating vortex, the clothes are often twisted into a ball, so the overall washing time is longer. Although the drum type uses less water than the upright type, the space in which the clothes can move is narrower, which restricts the tumbling of the clothes. Therefore, the cleaning power of the clothes is relatively poor, and it takes longer to wash the clothes.

[0005] In view of this, in order to overcome the shortcomings of the conventional solutions, the inventor has developed an improved solution for a reciprocating washing machine through active thinking, prototype testing and improvement, which can completely solve or effectively improve many shortcomings of the conventional solutions.

[0030] A reciprocating operation unit 30 is arranged in the washing machine housing 10. The reciprocating operation unit 30 includes a driving motor 31, a guide rod 32 and a reciprocating pressure plate 33. The driving motor 31 is arranged at an end of the washing outer tub 21 corresponding to the first through hole 212. The driving motor 31 has a gear 311. The guide rod 32 is simultaneously penetrated through the first through hole 212 and the second through hole 222. The guide rod 32 has a first end 321 and a second end 322 arranged opposite to each other. A tooth portion 323 is formed on the top surface close to the first end 321. The tooth portion 323 is meshed with the gear 311. A limiting groove 324 is recessed on the bottom surface of the guide rod 32 corresponding to the tooth portion 323. The limiting member 224 can move in the limiting groove 324, and the guide rod 32 is connected to the second end 322. There is a rotating head 34, and a bearing 341 is provided between the rotating head 34 and the guide rod 32, so that the rotating head 34 can rotate 360 ​​degrees relative to the guide rod 32 by the bearing 341. The reciprocating pressure plate 33 has a rotating shaft 331, and the reciprocating pressure plate 33 is pivotally connected to the rotating head 34 by the rotating shaft 331. Therefore, the guide rod 32 can be driven by the driving motor 31 and can link the reciprocating pressure plate 33 to move back and forth in the center of the washing inner drum 22. In the embodiment of the present invention, the reciprocating pressure plate 33 can be made of any shape and any material as long as it does not damage the shape and material of the clothes. Two springs 332 are provided on the side of the rotating shaft 331.

[0032] See also Figure 7 And with Figure 1 As shown, when the present invention is used, the cover 11 is first opened, and the clothes to be washed are put into the washing inner drum 22 through the first opening 211 and the second opening 221. After the clothes are put into the washing inner drum 22, the cover 11 is closed, and the control operation part 42 is pressed to drive the dehydration motor 23 and the driving motor 31 to operate. At this time, since the toothed part 323 is meshed with the gear 311, the guide rod 32 can be driven by the driving motor 31, and can be linked to the reciprocating pressure plate 33 to move back and forth in the center of the washing inner drum 22 to disturb and squeeze the clothes and water. At the same time, the dehydration motor 23 can be linked to the belt 25 to rotate, so that the belt 25 drives the washing inner drum 22 to rotate, so as to cooperate with the guide rod 32 and the reciprocating pressure plate 33 to help turn the clothes in the process of reciprocating movement, and to perform dehydration of the clothes. Therefore, the present invention can reduce the amount of water used for washing and the time consumed, and improve the efficiency of washing clothes.

[0033] The limiting member 224 is accommodated in the receiving groove 223 , so that when the guide rod 32 moves back and forth in the center of the inner drum 22 , it will be stopped by the limiting member 224 to prevent the guide rod 32 from rotating.

[0034] It is worth mentioning that Figure 6 As shown, the rotating head 34 can rotate relative to the guide rod 32 by the bearing 341, so that the rotating head 34 can be linked to the reciprocating pressure plate 33 pivotally connected thereto to rotate 360 ​​degrees. At the same time, the reciprocating pressure plate 33 can generate a swing angle of 0 to 45 degrees by the elastic restoring force of the springs 332, which can effectively disturb and squeeze the clothes and water, thereby improving the efficiency of washing clothes.
