[0024] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] Example: Figure 1As shown, the foot-operated washing machine of this embodiment includes a body 1 and a washing drum 2, and the body 1 is provided with a washing compartment and an installation cavity spaced apart from each other in an upper and lower direction. The washing drum 2 includes an outer drum 21 and an inner drum 22, and the outer drum 21 is installed in the washing compartment. A rotating shaft 23 is provided in the middle of the bottom of the inner drum 22, which vertically passes through the bottom wall of the outer drum 21. The rotating shaft 23 is rotatably connected to the bottom wall of the outer drum 21. The lower end of the rotating shaft 23 extends into the washing cavity and is coaxially equipped with a driving gear 4. A main shaft 3 is provided in the installation cavity, which passes through the side walls of the main shaft and is rotatably connected to the main shaft. Foot pedal assemblies 10 are respectively provided at both ends of the main shaft 3 for driving the main shaft to rotate. At the lower end of the rotating shaft 23, the main shaft 3 is connected to a reversing structure 5 that is transmission-connected to the driving gear 4. During the rotation of the main shaft 3, the reversing structure 5 drives the driving gear 4 to rotate alternately in forward and reverse directions, thereby driving the washing drum 2 to rotate forward and reverse.

[0026] The usage process is as follows:

[0027] The user loads laundry and water into the washing drum 2 and steps on the pedal assemblies 10 at both ends of the main shaft 3 with their feet, driving the main shaft 3 to rotate. During the rotation of the main shaft 3, the reversing structure 5 drives the drive gear 4 and the rotating shaft 23 to rotate alternately forward and reverse, thereby driving the washing drum 2 to rotate alternately forward and reverse, generating centrifugal force to clean the laundry in the washing drum 2. During the forward and reverse rotation of the washing drum 2, the friction between the clothes and the drum wall is enhanced, thereby achieving the effect of purifying the clothes. The entire washing machine fully utilizes the human body's energy to achieve energy conservation. Compared with traditional electric washing machines, it has greater energy conservation and emission reduction potential. At the same time, the washing machine integrates leisure, fitness, and laundry functions, making it particularly suitable for home use, especially for people with disabilities. Washing can still be done in places without electricity, without the need for hand washing.

[0028] As a preferred embodiment, Figure 1 and 2 As shown, the outer drum 21 can be lifted and lowered in the washing compartment, and can be moved upward until the driving gear 4 is separated from the reversing structure 5, or moved downward until the driving gear 4 is connected and matched with the reversing structure 5.

[0029] In this embodiment, the pedal assembly 10 can be the pedal assembly 10 on a bicycle, which is a prior art and will not be described in detail here.

[0030] In the above embodiment, during use, by raising and lowering the washing drum 2, the rotating shaft 23 and the driving gear 4 can be driven to rise and fall, so that the driving gear 4 is separated from or connected to the reversing structure 5. When separated, external force acts on the foot pedal assembly 10, and the washing drum 2 does not rotate, and only has the effect of stepping on fitness. When the driving gear 4 is connected to the reversing structure 5, external force acts on the foot pedal assembly 10, and the washing drum 2 rotates to wash clothes at the same time. The entire structural design is relatively ingenious and can realize switching between different functions and states.

[0031] As a preferred embodiment, Figure 1 、 2 As shown, it also includes a manual drive component 6, which includes a first gear 61, a second gear 62 and a rocker 63. The first gear 61 is horizontally arranged and rotatably assembled in the installation cavity. The first gear 61 includes a first spur gear ring and a first bevel gear portion coaxially arranged at the lower end of the first spur gear ring. The first spur gear ring of the first gear 61 is located on one side of the driving gear 4. The outer cylinder 21 can move upward until the driving gear 4 is separated from the reversing structure 5 and the driving gear 4 is meshed with the first spur gear ring of the first gear 61, or move downward until the driving gear 4 is connected to the reversing structure 5 and the driving gear 4 is separated from the first spur gear ring of the first gear 61. The second gear 62 is a bevel gear matching the first bevel gear portion of the first gear 61. The second gear 62 is vertically rotatably assembled in the installation cavity and meshes with the first bevel gear portion of the first gear 61. The rocker 63 passes through the hole on the side wall of the installation cavity and is coaxially detachably connected to the second gear 62. The rocker 63 is used to drive the second gear 62 to rotate.

[0032] In the above embodiment, after the washing drum 2 is raised, the driving gear 4 is separated from the reversing structure 5. At the same time, the driving gear 4 is engaged with the first spur gear ring of the first gear 61. In this state, the inner drum 22 of the washing drum 2 is driven by the manual drive component 6 to rotate in one direction to realize the dehydration function. In the entire design, the two functions of manual dehydration and washing are flexibly and reasonably switched, which is very convenient to use.

[0033] In the above embodiment, a connector is coaxially provided at one end of the second gear 62, and the end of the connector is provided with a socket that is plugged into the rocker 63. The socket is not a round hole, and one end of the rocker 63 is also not a round head, ensuring that the second gear 62 can be smoothly driven to rotate after being inserted into the socket.

[0034] In this embodiment, the diameter of the second gear 62 is larger than the diameter of the driving gear 4. The purpose of this design is: when the rocker 63 drives the second gear 62 to rotate, since the diameter of the second gear 62 is larger than the diameter of the driving gear 4, the rotation speed of the driving gear 4 will be faster than that of the second gear 62, thereby realizing high-speed rotation and dehydration of the inner drum 22.

[0035] It should be noted that in the above embodiment, the first gear 61 is a combination of a bevel gear and a spur gear, which is an integrally formed gear component and is a heterosexual gear. However, this heterosexual gear belongs to the existing technology and can be modified from a conventional gear. It has been applied to a variety of transmission structures and will not be elaborated here.

[0036] As a preferred embodiment, Figure 4 As shown, the reversing structure 5 includes a third gear 51, a fourth gear 52, a fifth gear 53 and a sixth gear 54. The third gear 51 is a bevel gear and is coaxially assembled on the main shaft 3. The fourth gear 52 includes a second spur gear ring and a second bevel gear portion coaxially arranged at one end of the second spur gear ring. The fourth gear 52 is horizontally arranged and rotatably assembled in the mounting cavity. Its second bevel gear portion is meshed with the third gear 51. The fifth gear 53 and the sixth gear 54 are respectively horizontally arranged and rotatably assembled in the mounting cavity. The fifth gear 53 and the sixth gear 54 are both located below the driving gear 4 and mesh with each other. The second spur gear ring of the fourth gear 52 is meshed with the fifth gear 53 or the sixth gear 54. A plurality of first tooth columns 531 are provided at intervals along the circumference of the upper end of the wheel 53. The plurality of first tooth columns 531 are distributed in an arc shape, and the central angle of the arc is not greater than 180°. A plurality of second tooth columns 541 are provided at intervals along the circumference of the upper end of the sixth gear 54. The plurality of second tooth columns 541 are distributed in an arc shape, and the central angle of the arc is not greater than 180°. The outer cylinder 21 can move upward until the driving gear 4 is higher than the first tooth column 531 and the second tooth column 541, or move downward until the driving gear 4 is located to the side of the first tooth column 531 and the second tooth column 541. In this state, during the rotation of the fifth gear 53 and the sixth gear 54, one of the plurality of first tooth columns 531 and the plurality of second tooth columns 541 at the upper ends of the two gears engages with the teeth of the driving gear 4.

[0037] In the above embodiment, when the driving gear 4 moves downward to the side of the first gear column 531 and the second gear column 541 (in this state, the reversing structure 5 and the driving gear 4 are in a connected and matched state), the pedal assembly 10 applies an external force to drive the main shaft 3 to rotate, the main shaft 3 drives the third gear 51 to rotate, the third gear 51 drives the fourth gear 52 to rotate, and the fourth gear 52 drives the fifth gear 53 and the sixth gear 54 to rotate synchronously in the opposite direction. During the rotation of the fifth gear 53 and the sixth gear 54, the first gear column 531 and the second gear column 541 at their upper ends alternately engage with the teeth of the driving gear 4. Specifically, when the fifth gear 53 rotates to the multiple first gear columns thereon When 531 engages with the driving gear 4 one by one, it will drive the driving gear 4 to rotate in one direction until all the first gear columns 531 are separated from the driving gear 4. After separation, the second gear columns 541 on the sixth gear 54 engage with the driving gear 4 one by one. Since the fifth gear 53 and the sixth gear 54 rotate in opposite directions, the driving gear 4 rotates in the opposite direction while the second gear column 541 is engaged with the driving gear 4. This makes it possible for the driving gear 4 to rotate alternately forward and reverse through the reversing structure 5 during the rotation of the main shaft 3, thereby driving the inner drum 22 to rotate forward and reverse to realize the washing function. The entire design is very clever and effectively realizes the forward and reverse washing of the inner drum 22.

[0038] It should be noted that in the above embodiment, the fourth gear 52 is a combination of a bevel gear and a spur gear, which is an integrally formed gear component and is a heterosexual gear. However, this heterosexual gear belongs to the existing technology and can be modified from a conventional gear. It has been applied to a variety of transmission structures and will not be elaborated here.

[0039] It should be noted that: while the multiple first gear columns 531 on the fifth gear 53 are engaged with the driving gear 4 one by one, the multiple second gear columns 541 on the sixth gear 54 are gradually rotated from a position away from the driving gear 4 to a position close to the driving gear 4, until the first gear columns 531 rotate with the fifth gear 53 to separate from the driving gear 4, and the second gear columns 541 will engage with the teeth of the driving gear 4 one by one as the sixth gear 54 rotates.

[0040] As a preferred embodiment, the fifth gear 53 and the sixth gear 54 have the same specifications, and their diameters are larger than the diameter of the driving gear 4 , and the diameter of the third gear 51 is larger than the diameters of the fifth gear 53 and the sixth gear 54 .

[0041] In the above embodiment, the diameters of the fifth gear 53 and the sixth gear 54 are larger than the diameter of the driving gear 4, and the diameter of the third gear 51 is larger than the diameters of the fifth gear 53 and the sixth gear 54, which can change the output speed of the main shaft 3 so that the driving gear 4 obtains the speed, such as reversing after the driving gear 4 and the inner cylinder 22 rotate 1-2 circles.

[0042] As a preferred embodiment, Figure 1 、 2 As shown in Figure 3, an external threaded sleeve 211 is coaxially provided at the lower end of the outer cylinder 21, and an internal threaded sleeve 212 is provided on the bottom wall of the washing compartment. The external threaded sleeve 211 is screwed onto the outside of the internal threaded sleeve 212. The external threaded sleeve 211 can rotate relative to the internal threaded sleeve 212, thereby driving the outer cylinder 21 to rise and fall.

[0043] In the above embodiment, the height of the outer drum 21 in the washing compartment is adjusted by rotating the outer drum 21, thereby raising and lowering the driving gear 4 and switching between washing and non-washing (dehydration) functions.

[0044] As a preferred embodiment, a drain outlet is provided at a side end of the bottom wall of the outer cylinder 21 , and the drain outlet is connected to a drain main pipe 7 .

[0045] In the above embodiment, the laundry wastewater in the outer tub 21 is conveniently discharged through the drainage main 7 .

[0046] It should be additionally explained that the outer drum 21 is fixed in position and does not rotate during the washing process, while the inner drum 22 is driven to rotate.

[0047] As a preferred embodiment, Figure 3 As shown, a water storage tank 8 is provided at the bottom of the body 1 , and a water distribution pipe 9 connected to the water storage tank 8 is connected to the drainage main pipe 7 .

[0048] In the above embodiment, the design of the water storage tank 8 can collect and store the relatively clean rinsing water used for rinsing clothes in the outer drum 21 through the water distribution pipe 9, and use it for flushing toilets, etc., thereby saving water resources.

[0049] Optimally, a three-way valve is provided at the connection between the drainage main pipe 7 and the water distribution pipe 9 , and the three-way valve can adjust whether the waste water coming out of the outer cylinder 21 is discharged through the drainage main pipe 7 or the water distribution pipe 9 .

[0050] In this embodiment, all gears except the driving gear 4 are assembled in the body 1 through gear shafts or gear racks. This mounting structure belongs to conventional technology and will not be described in detail here.
