Description

Technical Field

[0001] This invention belongs to the field of clothing cleaning technology, and particularly relates to a pulsator washing machine. Background Technology

[0002] Washing machines have become a necessity in almost every household. Currently, washing machines exist in single-mode systems, such as pulsator washing and hand washing. Each of these washing modes has its advantages and disadvantages, and users' clothes are made of various materials. Single-mode washing cannot meet the needs of users to choose different washing modes for different clothes. At the same time, in the same washing machine with three washing modes, simply using a puller to operate the lever can cause the problem of grinding noise during spin-drying. Therefore, a braking structure is designed to address this issue, which can effectively avoid the grinding noise problem and accurately ensure the implementation of each washing mode.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] refer to Figure 1 An embodiment of the present invention provides a pulsator washing machine, which has a housing 1 for forming the exterior and an inner and outer drum assembly disposed within the housing 1. The inner and outer drum assembly consists of an outer drum 10 and an inner drum 9. The inner drum 9, which is rotatable relative to the outer drum 10, is disposed inside the outer drum 10, and the inner drum 9 and the outer drum 10 have a common axis. A rotatable pulsator 8 is disposed at the center of the inner drum 9. The pulsator 8 and the inner drum 9 have a common axis. Driven by a motor 11, the inner drum 9 and the pulsator 8 can rotate in the same direction, rotate in opposite directions, or the inner drum 9 can stop rotating while the pulsator 8 rotates.

[0021] At the lower end of the housing 1 and the lower end of the inner and outer drum assembly, a power control system 2 for the pulsator washing machine is provided. The power control system 2 is used to transmit the driving force generated by the motor 11 to the inner drum 9 and the pulsator 8 through reversing.

[0022] refer to Figure 2 The power control system 2 includes a gear control mechanism 21 connected to the motor 11, an input shaft mechanism 22, and a reduction mechanism 23 connected to the input shaft mechanism. The gear control mechanism 21 is provided with a connector 211. The connection between the input shaft mechanism 22 and the reduction mechanism 23 is changed by sliding the connector 211. The driving force reversed by the reduction mechanism 23 is input to the inner cylinder 9 and the impeller 8 by the output shaft mechanism 24.

[0023] refer to Figure 3 The gear control mechanism 21 of this embodiment includes: a motor upper gear 212 disposed between the connector 211 and the motor 11, the motor upper gear 212 being fixedly connected to the output shaft of the motor 11; an input shaft mechanism 22 disposed on the inner ring of the connector 211, the input shaft mechanism 22 including a spin-drying input shaft 222 and a washing input shaft 221 disposed on the inner ring of the spin-drying input shaft 222; the inner ring of the connector 211 is always engaged with the spin-drying input shaft 222; the motor upper gear 212 is engaged with or disengaged from the connector 211 by sliding the connector 211; the washing input shaft 221 is directly connected to the motor 11 and is used to input the main driving force of the motor 11 to the reduction mechanism 23; the washing input shaft 221 and the spin-drying input shaft 222 can rotate independently of each other.

[0024] A reducer housing 25 for mounting the reducer 23 is provided on the outside of the reducer mechanism 23. A gear seat 223 is provided on the top surface of the reducer housing 25 near the connector 211. The gear seat 223 has internal teeth that can mesh with the connector 211. At the same time, the connector 211 meshes with the dehydration input shaft 222. When the connector 211 meshes with the gear seat 223, the connector 211 meshes with the dehydration input shaft 222. Since the gear seat 223 is fixed, the dehydration input shaft 222 is fixed when the connector 211 and the gear seat 223 are in contact. When the connector 211 disengages from the gear seat 223, the connector 211 meshes with the upper gear 212 of the motor, and the driving force of the motor 11 is transmitted to the dehydration input shaft 222 through the upper gear 212 of the motor, so that the dehydration input shaft 222 and the washing input shaft 221 rotate in the same direction.

[0025] The output shaft mechanism 24 includes a washing output shaft 241 and a spin-drying output shaft 242. The washing output shaft 241 transmits the driving force through the reduction mechanism 23 to the impeller 8, and the spin-drying output shaft 242 transmits the driving force through the reduction mechanism 23 to the inner drum 9.

[0026] The reduction mechanism 23 located inside the reducer housing 25 is a planetary gear train, including a brake housing 233 for supporting the planetary gear train. One end of the brake housing 233 is connected to the spin-dry input shaft 222, and the other end is connected to the spin-dry output shaft 242. The end of the washing input shaft 221 is a sun gear 231, and planetary gears 232 are arranged around the sun gear 231. While the planetary gears 232 mesh with the sun gear 231, the center of the planetary gears 232 is rotatably connected to the planet carrier 234. The planet carrier 234 rotates under the drive of the planetary gears 232. The center of the planet carrier 234 is fixedly connected to the washing output shaft 241, which transmits the driving force of the motor 11 to the reduction mechanism.

[0027] refer to Figures 1 to 5In order to realize that the engagement relationship of the connector 211 can be changed by sliding, the embodiment of the present invention provides a washing actuator 4 in the housing 1, a pull block 43 and a tension spring 44 connected to the washing actuator 4. The tension spring 44 is hinged to one end of the lever 3, and the other end of the lever 3 is forked and abuts against the connector 211. The washing actuator 4 pulls the pull block 43, which drives the lever 3 hinged to the tension spring 44 to rotate, so that the lever 3 pushes the connector 211 to move. Since the connector 211 moves with the rotation of the lever 3, the first position, the second position and the third position of the connector 211 are equivalent to the first position, the second position and the third position of the lever 3.

[0028] refer to Figure 5 The first position of connector 211 is that connector 211 meshes with the upper gear 212 of motor 11, causing washing input shaft 221 and spin-drying input shaft 222 to rotate in the same direction, and inner drum 9 and impeller 8 to rotate in the same direction. (Reference) Figure 6 The second position of connector 211 is between the first and third positions. Connector 211 simultaneously disengages from the motor upper gear 212 and gear seat 223, freeing connector 211, the spin-drying input shaft 222, the brake housing 233, and the spin-drying output shaft 242. That is, the inner drum 9 is in a free state. When clothes are placed inside the inner drum 9, the inner drum 9 rotates in the opposite direction to the impeller 8. (Refer to...) Figure 7 In the third position of the connector 211, the connector 211 is disengaged from the upper gear 212 of the motor, and the lower end of the connector 211 is engaged with the gear seat 223, that is, the inner cylinder 9 is in a locked state and the impeller 8 rotates.

[0029] To ensure that the connector 211 is precisely positioned in the first, second, and third positions, the washing actuator 4 in this embodiment of the invention has three strokes. When the washing actuator 4 is in the first washing stroke, it is in a standby state, and the connector 211 is in the first position under the action of gravity (a compression spring can also be provided between the connector 211 and the gear seat 223 to push the connector 211 to the first position). When the washing actuator 4 is in the second washing stroke, it pulls the lever 3, causing the lever 3 to move the connector 211 between the upper gear 212 and the gear seat 223 of the motor, thus placing the connector 211 in the second position. When the washing actuator 4 is in the third washing stroke, it pulls the lever 3 to engage the connector 211 with the gear seat 223.

[0030] refer to Figure 8The washing actuator 4 is provided with an outer fixed seat 45 and an inner fixed seat 46. The bottom surface of the inner fixed seat 46 and the bottom surface of the outer fixed seat 45 are fixed to the outer cylinder 10 by screws. The inner fixed seat 46 is located inside the outer fixed seat 45. The upper end of the inner fixed seat 46 is provided with a sliding groove 461. The upper surface of the outer fixed seat 45 is provided with a mounting hole. The outer fixed seat 45 is provided with a stepper motor 41 at the mounting hole. The output shaft of the stepper motor 41 passes through the mounting hole and is fixedly connected to a limiting rotating shaft 42. The limiting rotating shaft 42 rotates with the rotation of the output shaft of the stepper motor 41. At the end of the limiting rotating shaft 42, a blocking protrusion 421 facing the sliding groove 461 is provided. As the limiting rotating shaft 42 rotates, the blocking protrusion 421 moves back and forth along a circular path with the limiting rotating shaft 42 as the center. At the same time, the circular path of the blocking protrusion 421 intersects the sliding groove 461 of the inner fixed seat 46 at two positions.

[0031] A pull block 43 is provided inside the slide 461, for reference. Figure 9 The pull block 43 has grooves on both sides to prevent radial displacement when it slides in the slide groove 461. The upper end of the pull block 43 has a limiting protrusion 431. The highest point of the limiting protrusion 431 is higher than the lowest point of the blocking protrusion 421. When the blocking protrusion 421 is on the path of the slide groove 461, the blocking protrusion 421 prevents the pull block 43 from continuing to slide, ensuring that the pull block 43 is in the predetermined position.

[0032] The washing actuator 4 is connected in sequence with a pull block 43, a tension spring 44 and a lever 3. The washing actuator 4 pulls the pull block 43, which drives the tension spring 44 to pull the lever 3 to rotate. The middle part of the lever 3 is provided with a lever pin fixed on the gear seat 223, so that the lever 3 rotates around the lever pin as the rotation center.

[0033] When the washing actuator 4 is in the first washing stroke, refer to Figure 5 The connector 211 engages with the toothed seat 223. At this time, the pull block 43 is at the end of the slide groove 461 away from the washing actuator 4, and the stepper motor 41 controls the limit shaft 42 to rotate, so that the blocking protrusion 421 abuts against the side of the limit protrusion 431 of the pull block 43 near the washing actuator 4, thereby canceling the vertical gap between the pull block 43 and the inner fixed seat 46, preventing the pull block 43 from shaking during washing, and limiting the shaking of the lever 3 and the tension spring 44. When the washing actuator 4 is in the second washing stroke, refer to Figure 6 The connector 211 is located between the toothed seat 223 and the upper tooth 212 of the motor. At this time, the pull block 43 is closer to the washing actuator 4 in the first washing stroke than the washing actuator 4. The stepper motor 41 controls the limit shaft 42 to rotate, so that the blocking protrusion 421 abuts against the side of the limit protrusion 431 of the pull block 43 near the lever 3, preventing the pull block 43 from shaking, and accurately positioning the connector 211 between the upper tooth 212 of the motor and the toothed seat 223.

[0034] When the washing actuator 4 is in the third washing cycle, refer to Figure 7 Connector 211 engages with tooth seat 223. At this time, pull block 43 is located at one end of slide groove 461 close to washing actuator 4. Stepper motor 41 controls limit shaft 42 to rotate, so that blocking protrusion 421 abuts against the limit protrusion 431 of pull block 43 near lever 3, preventing washing actuator 4 from suddenly losing power and causing the washing machine to make noise.

[0035] refer to Figure 1 and Figure 10 In an embodiment of the present invention, a dehydration traction device 5, a brake band control lever 6, a drain valve 7, and a brake band 63 are provided inside the housing 1. The drain valve 7 has a dual-stroke function. When the drain valve 7 is in the first drain stroke, the drain valve 7 does not drain water. When the drain valve 7 is in the second drain stroke, the drain valve 7 drains water from the inner and outer cylinder assembly. The dehydration traction device 5 simultaneously controls the brake band control lever 6 and the drain valve 7. The brake band 63 passes through the reducer housing 25 and is connected to the brake housing 233. The brake band 63 is controlled by the brake band control lever 6 to restrict the rotation of the brake housing 233 or to release the restriction of the brake housing 233.

[0036] The brake band control lever 6 is equipped with a brake pin 61 for controlling the braking or releasing of the brake band 63. One end of the brake band 63 is fixed to the brake band control lever 6 via the brake band pivot 62, and the other end is fixed to the reducer housing 25 via the brake band screw 64.

[0037] When the connector 211 is in the first position, the brake band control lever 6 is controlled by the spin-drying actuator 5, opening the brake band 63 to release the restriction on the brake housing 233. The drain valve 7 is in the first drainage stroke. At this time, the pulsator washing machine enters the inner drum 102 washing mode, that is, the inner drum 9 and the pulsator 8 rotate in the same direction. When drainage is required, the spin-drying actuator 5 controls the drain valve 7 to enter the second drainage stroke. The brake band 63 is still open, and the drain valve 7 drains the water in the inner and outer drum assembly.

[0038] When the connector 211 is in the second position, the brake band control lever 6 is controlled by the spin-drying traction device 5, and the brake band 63 is opened to release the restriction on the brake housing 233. The drain valve 7 is in the first drain stroke. At this time, the pulsator washing machine enters the hand-wash mode, that is, the inner drum 9 and the pulsator 8 rotate in opposite directions.

[0039] When the connector 211 is in the third position, the brake band control lever 6 is controlled by the spin-drying traction device 5, which controls the brake band 63 to restrict the rotation of the brake housing 233. The rotation of the brake housing 233 is restricted by the spin-drying input shaft 222 and the brake band 63, thereby improving the safety of the pulsator washing machine. At this time, the drain valve 7 is in standby mode, and the pulsator washing machine enters the washing state of the pulsator 8, that is, the pulsator 8 rotates independently.

[0040] In an embodiment of the present invention, the motor 11 is a variable frequency motor, which has two modes, forward rotation and reverse rotation, depending on the washing mode of the pulsator washing machine. The motor 11 can also be replaced by a motor and a pulley.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
