Description

Technical Field

[0001] The invention relates to a cleaning machine, in particular to a manual washing machine. Background Art

[0002] Washing machines are a common tool in life and have a wide range of applications. However, the washing machines currently sold on the market are all electric. In some occasions where electrical appliances cannot be used, this type of washing machine is not suitable. For example, in schools, for safety reasons, the power of electrical appliances in each dormitory will be limited to a very low range. In addition to a few computers and electric lights, at most a few small fans or table lamps are used. As long as a high-power electrical appliance is used, it will trip immediately. Therefore, basically all colleges and universities have explicit regulations for students living on campus not to use washing machines in dormitories, which makes it very inconvenient for students to wash clothes. In addition, for some remote areas with power shortages, electricity itself is a scarce energy source, let alone electric washing machines. For example, herders in Africa, India, Southeast Asia, Kazakhstan, Kyrgyzstan, Tajikistan and other regions cannot wash clothes in a timely and effective manner when they go out for nomadic travel in summer. Therefore, it is necessary to invent a washing machine that does not require electricity to facilitate washing clothes. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 10As shown, the present invention provides a manual washing machine, including a base 1, an outer drum 2, an inner tank 3 and an operating part 4, wherein the outer drum 2 is transversely fixed on the base 1, and a water inlet 5 and a water outlet 6 are provided on the outer drum 2, and the operating part 4 is sealed and connected at the port of the outer drum 2, the inner tank 3 is located in the outer drum 2, and the bottom center of the inner tank 3 is installed at the bottom center of the outer drum 2 through a bearing, and a detent disc 7 is provided at the front opening of the inner tank 3, and a detent disc connector 8 is also provided between the detent disc 7 and the inner tank 3, and the detent disc 7, the detent disc connector 8 and the inner tank 3 are synchronously engaged and positioned in the circumferential direction; the operating part 4 includes an end cover 4 1. Rotating cover 42, gear box 43, operating handle 44, central rotating shaft 45 and bearing assembly 46 on central rotating shaft 45. The gear box 43 has a central gear 431, a transmission gear 432 and a gear ring 433 meshing with each other. The gear box 43 also includes a left box cover 434, a right box cover 435 and a gear fixing plate 436. The center hole of the transmission gear 432 is fixed on the gear fixing plate 436 through a bearing. The center hole of the gear fixing plate 436 is fixed on the bearing assembly 46. The inner side of the end cover 41 is also provided with an outer sealing cover plate 47 and an inner sealing cover plate 48. The outer sealing cover plate 48 is provided with a central sealing cover plate 47 and an inner sealing cover plate 48. The outer side of the cover plate 47 is inserted into the step at the front end of the outer cylinder 2 and is sealed to the side wall of the outer cylinder 2, and the inner side of the outer sealing cover plate 47 is sealed to the off-disc connector 8; the outer side of the inner sealing cover plate 48 is sealed to the outer sealing cover plate 47, and the inner side of the inner sealing cover plate 48 is sealed to the gear fixing plate 436. The outer cylinder 2, the outer sealing cover plate 47, the inner sealing cover plate 48, the gear fixing plate 436, the bearing assembly 46, and the off-disc 7 form a closed area, the gear ring 433 is synchronously connected to the rotating cover 42, and the central position of the rotating cover 42 is provided with a washing operation hole 421, and the operating handle 44 is inserted into the outer sealing cover plate 48. After entering the washing operation hole 421, it is circumferentially engaged with the central rotating shaft 45 for positioning. The rotating cover 42 is provided with a dehydration operation hole 422 at a position offset from the center. The operating handle 44 is inserted into the dehydration operation hole 422 to drive the rotating cover 42 to rotate. The central rotating shaft 45 passes through the central hole of the central gear 431 in the gear box 43 and is connected with the central hole of the dehydration tray 7. A keyway is provided on the central rotating shaft 45. The central hole of the central gear 431 and the central hole of the dehydration tray 7 are circumferentially synchronously positioned and connected with the central rotating shaft 45 through a connecting key. The central rotating shaft 45, the central gear 431, the dehydration tray 7 and the inner tank 3 rotate synchronously.

[0024] Preferably, a protective cover 49 is provided on the outside of the end cover 41, one end of the protective cover 49 is hinged to one side of the end cover 41, and the other end is buckled and connected to the other side of the end cover 41 to prevent the end cover 41 from opening during washing or dehydration, thereby ensuring the sealing of the entire washing machine.

[0025] When in use, open the operating part 4, put the clothes to be washed in the inner tank 3, put the corresponding amount of washing powder or washing liquid, close the operating part 4, close the water outlet 6, inject clean water into the water inlet 5 of the outer drum 2, close the water inlet 5 when the water level is appropriate, insert the operating handle 44 into the washing operation hole 421, and turn the operating handle 44 to wash clothes. While the operating handle 44 rotates, the central shaft 45 rotates synchronously. According to the characteristics of its own structure, on the one hand, the off-disc 7 rotates synchronously with the central shaft 45 under the drive of the central shaft 45, and drives the off-disc connecting piece 8 and the inner tank 3 to rotate synchronously, so that the clothes are rolled and washed in the inner tank 3. On the other hand, the central gear 431 rotates synchronously with the central shaft 45, and drives the ring gear 433 to rotate through the transmission gear 432. The ring gear 433 synchronously drives the rotating cover 42 to rotate. Here, the rotating cover 42 only does its own idling and does not participate in the washing process. During the washing process, the water outlet 6 is opened to discharge dirty water according to the situation, and the clothes are washed clean after repeated water filling and drainage, and then the dehydration process is entered. During dehydration, the water outlet 6 is opened, the operating handle 44 is pulled out from the washing operation hole 421, inserted into the dehydration operation hole 422, and the operating handle 44 is rotated. The operating handle 44 drives the rotating cover 42 to rotate, and the rotating cover 42 drives the ring gear 433 to rotate synchronously. The ring gear 433 drives the central gear 431 to rotate through the transmission gear 432. The high-speed rotation of the central gear 431 is achieved through the transmission ratio of the gear system, and the rotation speed of the central shaft 45 can be easily reached above 600 revolutions per minute. At the same time, the rotation speed of the inner tank 3 is equal to the rotation speed of the central shaft 45, and the centrifugal dehydration operation is completed. The dehydrated water is discharged in time through the water outlet 6 to realize the dehydration process of the clothes. After the dehydration is completed, the operating part 4 is opened to take out the clothes for drying.
