Description

Technical Field

[0001] This invention relates to a washing machine, and more particularly to a spherical inner drum washing machine. Background Technology

[0002] There are two main types of washing machines: drum washing machines where the drum rotates along a horizontal axis and impeller washing machines where the impeller rotates along a vertical axis. Because both types of washing machines have a single axis of rotation, they are not conducive to thoroughly washing clothes.

[0003] Chinese invention patent application CN1869315A discloses a rotating ball washing machine and its method. It uses a ball as a clothing carrier, with the inner ball rotating within the outer shell along any axis, causing the clothes to rotate in any direction. The inner ball's motion can be broadly categorized into two types: basic motion and complex motion. The rotating ball washing machine consists of an outer shell, an outer door, several supports, and the ball. When the washing machine is not in operation, both rotating axes are closed; when the washing machine is in operation, one rotating axis is closed while the other is open, allowing the washing machine to rotate around the closed axis. By switching the opening and closing of the two rotating axes, the inner ball can rotate around different axes, thus achieving better washing results. However, as described on page 5, paragraph 2 of the patent specification, the design of the motion switching control part between the two axes is relatively complex, and the patent does not provide a specific structure for realizing the two-axis motion, making it difficult to implement in industrial production.

[0004] In view of this, this application has conducted an in-depth study on the structure of a spherical inner drum washing machine, which led to this case. Summary of the Invention

[0005] The purpose of this invention is to provide a spherical inner drum washing machine that has good washing effect, simple structure, and can be industrially produced.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spherical inner drum washing machine includes a first bracket and a second bracket arranged opposite to each other, an outer drum located between the first bracket and the second bracket, and an inner drum located in the inner cavity of the outer drum. The outer drum includes a lower sphere with an upper opening at its upper end and an upper spherical cover covering the upper opening. The inner drum includes a spherical body with an inner opening and an inner spherical cover covering the inner opening. The spherical body and / or the inner spherical cover have multiple through holes. A drive ring located on the radial section of the spherical body is fixedly sleeved on the outer side of the spherical body. An annular groove arranged circumferentially on the outer side wall of the drive ring is formed. An annular rack is provided on the side wall of the annular groove. A sliding ring is slidably sleeved on the drive ring. A first transmission shaft rotatably connected to the first bracket is fixedly connected to the sliding ring. The first transmission shaft is horizontally arranged and a rotary motor is drivenly connected to the first transmission shaft. A second transmission shaft is rotatably connected to the second bracket. One end of the second transmission shaft passes through the lower sphere and is fixedly connected to a gear that meshes with the annular rack. A swing motor is drivenly connected to the second transmission shaft.

[0008] As an improvement of the present invention, both the first drive shaft and the second drive shaft are provided with a braking device.

[0009] As an improvement of the present invention, a rotary encoder is provided on the first drive shaft and / or the second drive shaft.

[0010] As an improvement of the present invention, the upper part of the lower sphere is connected to a water inlet pipe, and the bottom part is connected to a water outlet pipe.

[0011] As an improvement of the present invention, a filter box is provided on the inner sidewall of the spherical body. The filter box includes an outer box body connected to the spherical body and an inner box body located in the inner cavity of the outer box body. The outer peripheral wall of the outer box body has a water outlet at one end near the connection position between the spherical body and the filter box, and a water inlet at the other end. The inner box body has an open opening at the position corresponding to the water inlet, and a plurality of filter holes are provided on the sidewall of the inner box body.

[0012] As an improvement of the present invention, an inlet baffle is provided on the water inlet hole and an outlet baffle is provided on the water outlet hole. One end of the inlet baffle is rotatably connected to the outer box and the other end abuts against the inner side wall of the outer box. One end of the outlet baffle is rotatably connected to the outer box and the other end abuts against the outer side wall of the outer box.

[0013] As an improvement of the present invention, a washboard rib is fixedly connected to the inner sidewall of the spherical body and / or the inner spherical cover.

[0014] As an improvement of the present invention, it also includes a chassis, wherein the first bracket, the second bracket and the outer shell are all located in the inner cavity of the chassis.

[0015] By adopting the above solution, the present invention has the following beneficial effects:

[0016] 1. By setting a drive ring, a sliding ring, and two transmission shafts, it can not only drive the inner tank to rotate along the horizontal axis, but also drive the inner tank to rotate along the vertical axis.

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-7 As shown, this embodiment provides a spherical inner drum washing machine, including a first support 10 and a second support 20 arranged opposite to each other, an outer drum 30 located between the first support 10 and the second support 20, and an inner drum 40 located in the inner cavity of the outer drum 30. Of course, for aesthetics and ease of operation, the spherical inner drum washing machine provided in this embodiment also includes a square-shaped casing 50, and the first support 10, the second support 20 and the outer drum 30 are all located in the inner cavity of the casing 50.

[0044] The top of the casing 50 is equipped with a flip cover 51, allowing the user to operate the outer drum 30 and inner drum 40 located inside the casing 50 by opening the flip cover 51. The specific structure of the flip cover 51 is the same as that of the flip cover on the casing of a conventional pulsator washing machine, and will not be described in detail here. In addition, the side wall of the casing 50 is also equipped with an operation panel 52 and a detergent dispenser 53. The specific structure of the operation panel 52 and the detergent dispenser 53 is the same as that of the operation panel and detergent dispenser on a conventional drum washing machine, and will not be described in detail here either.

[0045] The first bracket 10 and the second bracket 20 are respectively fixedly connected to the bottom of the inner cavity of the casing 50, and the distance between them is greater than the diameter of the outer liner 30. The outer liner 30 includes a lower sphere 31 with an upper opening at the top and an upper spherical cover 32 covering the upper opening. The lower sphere 31 and the upper spherical cover 32 are fastened together, forming a spherical shape after fastening. Preferably, in this embodiment, the upper spherical cover 32 and the flip cover 41 are fixedly connected to each other by a connecting rod. In this way, when the flip cover 51 is opened, the upper spherical cover 32 will be moved away from the lower sphere 31, exposing the upper opening for easy access to clothing, making the operation more convenient. A support plate 33 is fixedly connected to the lower ball 31 and simultaneously fixedly connected to the casing 50, thus achieving a fixed connection between the lower ball 31 and the casing 50. Alternatively, the lower ball 31 can be connected to the casing 50 via a suspension rod, with a connection structure similar to that between the inner drum and casing in a conventional pulsator washing machine. In this case, the lower ball 31 can sway relative to the casing 50, which helps improve washing performance. Furthermore, a sealing structure, such as a sealing strip, is required between the lower ball 31 and the upper ball cover 32 to prevent water leakage during use.

[0046] The inner tub 40 includes a spherical body 41 with an inner opening and an inner spherical cover 42 covering the inner opening. One side of the inner spherical cover 42 is rotatably connected to the spherical body 41, and the corresponding other end is connected to the spherical body 41 by a latch. This helps prevent the inner spherical cover 42 from detaching when the inner tub 40 rotates, and also facilitates opening the inner spherical cover 42 for taking out and putting in clothes. The spherical body 41 and / or the inner spherical cover 42 have multiple through holes. In this embodiment, it is described as if both the spherical body 41 and the inner spherical cover 42 have multiple evenly distributed through holes, allowing water to flow between the inner tub 40 and the outer tub 30. Preferably, a scrubbing rib 45 is fixedly connected to the inner sidewall of the spherical body 41 and / or the inner spherical cover 42, which helps to further improve washing performance.

[0047] A drive ring 43 is fixedly fitted onto the outer side of the spherical body 41, located on the radial section of the spherical body 41. That is, the plane where the drive ring 43 is located is also the radial section of the spherical body 41, so as to ensure that the drive ring 43 can drive the inner liner 40 to rotate around one of the diameters of the inner liner 40. An annular groove 44 is formed on the outer side wall of the drive ring 43, which is arranged circumferentially along the drive ring 43. An annular rack 47 is provided on the side wall of the annular groove 44.

[0048] A sliding ring 48 is slidably sleeved on the outer side of the drive ring 43. Specifically, the inner sidewall of the sliding ring 48 has a groove, and the drive ring 43 is embedded in the groove and can slide within it. A first drive shaft 11 is fixedly connected to the sliding ring 48 and rotatably connected to the first bracket 10. The first drive shaft 11 is horizontally arranged and located radially on the inner liner 40. A rotary motor 12 is drivenly connected to the first drive shaft 11. Specifically, the rotary motor 12 and the first drive shaft 11 are connected by a belt assembly. In addition, a horizontally arranged second drive shaft 21 is rotatably connected to the second bracket 20. The second drive shaft 21 is on the same straight line as the first drive shaft 11, and one end of the second drive shaft 21 passes through the lower ball 31 and is fixedly connected to a gear 46 that meshes with the annular rack 47. Of course, the lower ball 31 needs to have a through hole for the second drive shaft 21 to pass through. A swing motor 22 is drivenly connected to the second drive shaft 21, and the swing motor 22 and the second drive shaft 21 are also connected by a belt assembly.

[0049] Preferably, a horizontally arranged hollow rod is fixedly connected between the outer liner 30 and the second support 20, and the second drive shaft 21 is inserted through the hollow rod. This helps to improve the connection firmness of the outer liner 30. A bearing can be installed between the hollow rod and the second drive shaft 21 for better support.

[0050] Preferably, both the first drive shaft 11 and the second drive shaft 21 are equipped with a brake device 12. This brake device is a conventional device that can be purchased directly from the market. Its function is to stop the inner tub 30 at a designated position. The first drive shaft 11 and / or the second drive shaft 12 are also equipped with a rotary encoder (not shown in the figure) so that the control system can know the rotation angle and swing angle of the inner tub 30, thereby ensuring that when the washing machine stops, the inner tub 30 can be controlled to rotate to a position with the inner opening facing upward, so that the position of the inner opening of the washing machine corresponds to the upper opening.

[0051] The upper part of the lower ball body 31 is connected to a water inlet pipe 60, and a detergent dispenser 53 is connected to the water inlet pipe 60, so that the detergent placed in the detergent dispenser 53 can be flushed into the outer tank 30 through the water inlet pipe 60. The bottom of the lower ball body 31 is connected to a water outlet pipe 70 for draining water from the outer tank 30, and an on / off valve is installed on the water outlet pipe 70.

[0052] Preferably, a filter box 80 is provided on the inner wall of the spherical body 41. The filter box 80 includes an outer box 81 connected to the spherical body 41 and an inner box 82 located in the inner cavity of the outer box 81. The outer peripheral wall of the outer box 41 has an outlet hole at one end near the connection point between the spherical body 41 and the filter box 80, and an inlet hole at the other end (i.e., the end of the outer peripheral wall of the outer box 41 away from the connection point between the spherical body 41 and the filter box 80). Multiple inlets and outlets are arranged around the outer peripheral wall of the outer box 41. The inner box 82 has an opening at a position corresponding to each inlet hole. Specifically, the opening is located at the end of the inner box 82 away from the connection point between the spherical body 41 and the filter box 80. Except for the end with the opening, all sidewalls of the inner box 82 are tightly attached to the outer box 41. Multiple filter holes are provided on the inner sidewalls of the inner box 82. In addition, each water inlet is provided with a water inlet baffle 83 and each water outlet is provided with a water outlet baffle 84. One end of the water inlet baffle 83 is rotatably connected to the outer box 81, and the other end abuts against the inner sidewall of the outer box. In this way, when water flows into the outer box 81 from outside, it will push open the water inlet baffle 83, and vice versa. One end of the water outlet baffle 84 is rotatably connected to the outer box 81, and the other end abuts against the outer sidewall of the outer box 81. In this way, after the water entering the outer box 81 enters the inner box 82 through the open opening, it will flow out through the filter holes and the water outlet, while the dirt in the water will be left in the inner box 82. Conversely, it will be blocked by the water outlet baffle 84, effectively preventing the dirt in the inner box 82 from being washed out by the water.

[0053] In use, manually flip the cover 51. During this process, the upper ball cover 32 will also be opened by the connecting rod. Then, remove or flip the inner ball cover 42, place the clothes into the inner cavity of the inner liner 40, and then close the inner ball cover 42 and the cover 51 in sequence. At the same time as closing the cover 51, the upper ball cover 32 will also cover the lower ball 31 by the connecting rod. Then, add laundry detergent to the detergent dispenser 53 and inject water into the outer liner 30 through the water inlet pipe 60. During this process, the laundry detergent will also be flushed into the outer liner 30, and the water in the outer liner 30 will also enter the inner liner 40 through the through hole. Then use... The rotary motor 12 drives the drive ring 43 to rotate, causing the inner drum 40 to rotate along the horizontal axis to achieve washing. After washing is completed, the water in the outer drum 30 and the inner drum 40 is discharged through the water outlet pipe 70. Then, the rotary motor 12 drives the drive ring 43 to rotate, causing the inner drum 40 to rotate horizontally to achieve dehydration. During washing and dehydration, the positioning motor 22 can drive the inner drum 40 to rotate along the vertical axis, changing the angle between the drive ring 43 and the inner drum 40 in turn, thereby changing the horizontal rotation axis of the inner drum 40 to achieve rotational movement along different rotation axes, so as to achieve better washing effect.

[0054] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various changes and applications to the present invention based on the prior art, and these all fall within the protection scope of the present invention.
