For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1-7 As shown, the present invention provides an inner barrel structure, including an inner barrel 1, on the inner wall of the inner barrel 1 is provided a stirring blade 2 extending radially of the inner barrel 1, one radially extending end of the stirring blade 2 is slidably connected to the inner wall of the inner barrel 1 along the axial direction of the inner barrel 1, and floats on the liquid surface of the inner barrel 1 under the action of liquid buoyancy.

[0043] In an embodiment of the present invention, the stirring blade 2 is arranged to be slidably connected to the inner wall of the inner barrel 1 along the axial direction of the inner barrel 1, so that the position of the stirring blade 2 can change with the change of the liquid level in the inner barrel 1, so that the stirring blade 2 can always be on the liquid surface of the inner barrel 1 under the action of the buoyancy of the liquid, and the clothes on the upper part of the inner barrel 1 can be turned over more easily, thereby expanding the turning area of ​​the clothes, realizing effective turning of the clothes, and improving the washing effect of the clothes.

[0044] The inner barrel 1 structure is used in a pulsator washing machine; the pulsator washing machine comprises an outer barrel and an inner barrel 1 arranged in the outer barrel, the outer barrel is a water storage barrel, the inner barrel 1 comprises a barrel body with openings at the top and bottom, the upper opening of the barrel body is a barrel mouth, and the lower opening of the barrel body is a barrel bottom with openings at the bottom of the barrel body; a pulsator is arranged at the bottom of the barrel for stirring clothes;

[0045] For example, when the weight of the clothes in the inner barrel 1 is a first weight, water is filled into the outer barrel to a first liquid level, and the stirring blade 2 slides to the first liquid level under the action of the buoyancy of the liquid and floats on the liquid surface of the first liquid level; when the weight of the clothes in the inner barrel 1 is a second weight greater than the first weight, water is filled into the outer barrel to a second liquid level, and the stirring blade 2 slides to the second liquid under the action of the buoyancy of the liquid and floats on the liquid surface of the second liquid level.

[0046] In the embodiment of the present invention, a support protrusion 3 is provided on the inner circumferential wall 11 of the inner barrel, and a sliding portion 31 extending along the axial direction of the inner barrel 1 is provided on the support protrusion 3, and one radially extending end of the stirring blade 2 is slidably connected to the sliding portion 31.

[0047] In the embodiment of the present invention, the inner circumferential wall 11 of the inner barrel is specifically the inner circumferential wall of the barrel body, and the stirring blade 2 is arranged on the inner circumferential wall of the barrel body; the supporting protrusion 3 protrudes relative to the inner circumferential wall 11 of the inner barrel, and the supporting protrusion 3 can also rub against the clothes to stir the clothes;

[0048] The sliding portion 31 on the supporting protrusion 3 can be: a sliding groove, a sliding through hole 311 or a sliding protrusion. When the supporting protrusion 3 is provided with a sliding protrusion, the corresponding stirring blade 2 is provided with a sliding groove; the sliding portion 31 cooperates with the stirring blade 2 to guide the sliding of the stirring blade 2;

[0049] like Figure 4-6 As shown, specifically, the interior of the support protrusion 3 is hollow, and the sliding portion 31 is a sliding through hole 311 that connects the interior of the support protrusion 3 with the interior of the inner barrel 1. One end of the stirring blade 2 extending radially is inserted into the sliding through hole 311, slides in the sliding through hole 311, and extends into the interior of the support protrusion 3 through the sliding through hole 311;

[0050] The sliding through hole 311 allows the interior of the supporting protrusion 3 to communicate with the interior of the inner barrel 1, so that the liquid in the inner barrel 1 can enter the supporting protrusion 3, so that the stirring blade 2 can fully contact the water in the inner barrel 1 and can stably float on the liquid surface of the inner barrel 1; one end of the stirring blade 2 extending radially extends into the interior of the supporting protrusion 3 through the sliding through hole 311, preventing the stirring blade 2 from falling out of the sliding through hole 311 during the sliding process.

[0051] Furthermore, the support protrusion 3 is in the shape of a long strip extending along the axial direction of the inner tub 1 and extending from the top to the bottom of the inner circumferential wall of the inner tub 1, and can play a role in rubbing and stirring the clothes in the upper and lower parts of the inner tub 1;

[0052] The sliding hole 311 extends from a position between the top and the middle of the supporting protrusion 3, so that the supporting protrusion 3 leaves a certain space at the upper part of the sliding hole 311 for arranging other components. The sliding hole 311 extends to the bottom of the supporting protrusion 3, so that the stirring blade 2 can float on multiple liquid levels of different heights in the inner barrel 1, and can adapt to different liquid level heights in the inner barrel 1, thereby improving the applicability of the stirring blade 2 for stirring and turning clothes.

[0053] The sliding through hole 311 is provided in the middle of the arc-shaped side wall of the supporting protrusion 3, which can increase the contact opportunity with the clothes and stir the clothes to the greatest extent;

[0054] The support protrusion 3 is integrally formed with the inner circumferential wall 11 of the inner barrel, or the support protrusion 3 is separately provided with the inner barrel 1, and the support protrusion 3 is installed on the inner circumferential wall of the inner barrel 1; the support protrusion 3 is arc-shaped and protrudes into the inner barrel 1, which can increase the contact opportunity with the clothes and reduce the wear on the clothes;

[0055] A plurality of filters 5 and a plurality of supporting protrusions 3 are arranged on the inner circumferential wall of the inner barrel 1 . All the filters 5 and all the supporting protrusions 3 are evenly distributed along the circumference of the inner barrel 1 , and the filters 5 and the supporting protrusions 3 are arranged alternately.

[0056] Furthermore, the support protrusion 3 is provided with a through hole 32 on one side of the sliding through hole 311, which is communicated with the inside of the support protrusion 3 and is provided for the sliding protrusion 21 to be inserted into. A through hole is provided on the top of the support protrusion 3, and the top of the sliding through hole 311 and the top of the through hole 32 are respectively communicated with the through hole 33;

[0057] The engaging through hole 32 is used to engage the sliding protrusion 21. When the stirring blade 2 is not in use, the sliding protrusion 21 can be rotated into the engaging through hole 32 through the through hole 33, so that the stirring blade 2 is rotated to one side of the sliding through hole 311 located in the middle of the supporting protrusion, so that the stirring blade 2 is offset toward the inner wall of the inner barrel 1, so as not to affect the placement and removal of clothes. Figure 4 This is the state of the stirring blade 2 when in use. Figure 5 This is the state when the stirring blade 2 is not in use.

[0058] Furthermore, the card-connecting through hole 32 is in an elongated strip shape and extends along the axial direction of the inner barrel 1 , and the bottom of the card-connecting through hole 32 extends downward to a position between the top and the middle of the sliding through hole 311 .

[0059] like Figure 4 , Figure 5 and Figure 7 As shown, in the embodiment of the present invention, the stirring blade 2 is cylindrical, the axis of the stirring blade 2 extends along the axial direction of the inner barrel 1, the axial cross-section of the stirring blade 2 is elliptical, and the radially extending end of the stirring blade 2 is the first end of the maximum diameter of the stirring blade 2. The first end of the maximum diameter of the stirring blade 2 is provided with a sliding protrusion 21, and the sliding protrusion 21 is inserted into the sliding through hole 311 and extends into the supporting protrusion 3 through the sliding through hole 311.

[0060] In the embodiment of the present invention, the sliding protrusion 21 slides in the sliding through hole 311 to enable the stirring blade 2 to slide on the peripheral wall of the inner barrel 1; the sliding protrusion 21 extends from the top of the stirring blade 2 to a position between the middle and bottom of the stirring blade 2.

[0061] Furthermore, a blocking convex portion 22 is provided on the side of the sliding convex portion 21 facing away from the stirring blade 2. The blocking convex portion 22 is cylindrical. The left and right sides of the blocking convex portion 22 are respectively protruded from the sliding convex portion 21. The top of the sliding through hole 311 is provided with an opening for the sliding convex portion 21 to be inserted into the sliding through hole 311. The blocking convex portion 22 can prevent the sliding convex portion 21 from being separated from the sliding through hole 311 during the sliding process and falling off the sliding through hole 311.

[0062] The supporting protrusion 3 on the periphery of the sliding through hole 311 is clamped between the stirring blade 2 and the blocking protrusion 22, reducing the shaking of the sliding protrusion 21 during the sliding process, improving the stability of the sliding protrusion 21 during the sliding process, and the stability during the stirring process of clothes.

[0063] The top of the blocking protrusion 22 extends upward to be flush with the top of the sliding protrusion 21, and the bottom of the blocking protrusion 22 extends downward to exceed the bottom of the sliding protrusion 21 and does not exceed the bottom of the stirring blade 2, so that a guide opening is formed between the blocking protrusion 22, the bottom of the sliding protrusion 21 and the stirring blade 2. When the sliding protrusion 21 is inserted into the sliding through hole 311, the guide opening guides the bottom of the sliding protrusion 21 to the top opening of the sliding through hole 311, so that the bottom of the sliding protrusion 21 enters the sliding through hole 311 through the opening.

[0064] The sliding protrusion 21 and the blocking protrusion 22 are made of elastic material, for example, the elastic material is rubber, so that the stirring blade 2 can be deformed when the impeller rotates in one direction, and swing along with the clothes, so that the clothes rotate in the same direction as the impeller, without blocking the movement of the clothes, thereby realizing the turning of the clothes on the upper part of the inner barrel 1.

[0065] like Figure 4 As shown, in an embodiment of the present invention, the outer peripheral wall of the stirring blade 2 between one end of the smallest diameter of the stirring blade 2 and the first end of the largest diameter of the stirring blade 2 protrudes to form a limiting portion 4, and the limiting portion 4 is a plate-like structure. The limiting portion 4 fits the outer periphery of the supporting protrusion 3 and extends from the inner periphery of the stirring blade 2 to the outer periphery, and extends to near the inner peripheral wall of the inner barrel 1.

[0066] In an embodiment of the present invention, the function of the limiting portion 4 is to limit the stirring blade 2 from swinging with the clothes when the impeller rotates in another direction, so that the stirring blade 2 blocks the clothes and limits the clothes from rotating in the direction opposite to the rotation direction of the impeller, so that the clothes at the lower part of the inner barrel 1 and the clothes at the upper part are exchanged, and the clothes are turned upside down, so that the impeller can fully stir the clothes at the upper part of the inner barrel 1.

[0067] The limiting part 4 limits the swing of the stirring blade 2 by fitting with the outer periphery of the supporting protrusion 3;

[0068] Furthermore, the distance between the limiting portion 4 and the end with the smallest diameter of the stirring blade 2 is greater than the distance between the limiting portion 4 and the first end with the largest diameter of the stirring blade 2 , which can improve the fitting strength between the limiting portion 4 and the supporting protrusion 3 .

[0069] More specifically, the stirring blade 2 is hollow inside, and a notch 23 is provided at the bottom of the stirring blade 2. The end opposite to the first end of the maximum diameter of the stirring blade 2 is the second end of the maximum diameter of the stirring blade 2. The top of the notch 23 extends from the second end of the stirring blade 2 from top to bottom gradually toward the first end of the stirring blade 2.

[0070] The interior of the stirring blade 2 is hollow, so that the stirring blade 2 is easily affected by the buoyancy of the liquid and floats on the liquid surface of the inner barrel 1 .

[0071] The purpose of the top of the notch 23 extending obliquely is to increase the contact area with the clothes and reduce the wear on the clothes.

[0072] like Figure 8 As shown, the present invention also provides a control method for a washing machine, which adopts the inner barrel 1 structure of the above technical solution. After the stirring blade 2 moves to the liquid surface of the inner barrel 1 under the action of the buoyancy of the liquid, the impeller in the inner barrel 1 rotates to stir the clothes, and the stirring blade 2 stirs the clothes on the upper part of the inner barrel 1 to turn the clothes over.

[0073] In the embodiment of the present invention, the stirring blades 2 stir the clothes on the upper part of the inner tub 1, so that the clothes on the upper part of the inner tub 1 can be turned over relatively easily, so that the clothes are turned over as a whole, thereby improving the washing effect of the clothes;

[0074] Furthermore, while the pulsator rotates in the first direction to stir the clothes in the inner tub 1, the stirring blade 2 rotates in the first direction to stir the clothes on the upper part of the inner tub 1 to turn over the clothes on the upper part of the inner tub 1;

[0075] The stirring blade 2 can be deformed and swing along with the rotation of the clothes on the upper part of the inner tub 1, without blocking the clothes, so that the clothes on the upper part of the inner tub 1 can rotate along with the pulsator. The main function of the stirring blade 2 is to turn over the clothes on the upper part of the inner tub 1. The rotation direction of the clothes on the upper part of the inner tub 1 is the same as that of the pulsator.

[0076] While the impeller rotates in the second direction to stir the clothes in the inner tub 1, the stirring blades 2 stir the clothes on the upper part of the inner tub 1 in a first direction opposite to the second direction, so that the clothes in the lower part of the inner tub 1 and the clothes in the upper part of the inner tub 1 are exchanged and the clothes are turned upside down.

[0077] The limiting part 4 on the stirring blade 2 limits the stirring blade 2, so that the stirring blade 2 does not swing with the rotation of the clothes on the upper part of the inner barrel 1. The stirring blade 2 blocks the clothes on the upper part of the inner barrel 1, so that the rotation direction of the clothes on the upper part of the inner barrel 1 is opposite to the rotation direction of the pulsator, so that the clothes on the lower part of the inner barrel 1 and the clothes on the upper part of the inner barrel 1 rotate in the opposite direction, so that the clothes on the lower part of the inner barrel 1 and the clothes on the upper part of the inner barrel 1 are exchanged, and the clothes are turned upside down, so that the pulsator washes the clothes in all directions.

[0078] For example, when the pulsator rotates counterclockwise, the clothes on the upper part of the inner tub 1 rotate counterclockwise, and the clothes first hit one side of the stirring blade 2. After the stirring blade 2 stirs the clothes, the clothes on the upper part of the inner tub 1 still rotate counterclockwise;

[0079] The pulsator rotates clockwise, and the clothes on the upper part of the inner tub 1 rotate clockwise. The clothes first hit the other side of the stirring blade 2 provided with the limit part 4, and the stirring blade 2 blocks the clothes, so that the clothes on the upper part of the inner tub 1 rotate counterclockwise, so that the clothes on the lower part of the inner tub 1 mainly stirred by the pulsator and the clothes on the upper part of the inner tub 1 mainly stirred by the stirring blade 2 are exchanged, so that the clothes are turned upside down;

[0080] The pulsator rotates counterclockwise and clockwise alternately, which can turn the clothes upside down and reduce the entanglement of the clothes.

[0081] Specifically, the stirring blade 2 is inserted into the sliding through hole 311. After the stirring blade reaches the liquid level height of the inner tub 1, the clothes are washed with a conventional water flow. The conventional water flow washing belongs to normal washing, which can ensure that the clothes are clean and the entanglement is not serious. When there are many clothes, the clothes in the lower part of the inner tub 1 are washed with a conventional water flow first;

[0082] After the conventional water flow washing is finished, the clothes are washed with the reverse water flow. After washing the clothes in the lower part of the inner tub 1 for a certain period of time, the water flow intensity is increased, and the clothes in the upper part of the inner tub 1 are stirred by the stirring blades 2. The clothes in the upper part and the lower part of the inner tub 1 are exchanged, and the clothes in the upper part of the inner tub 1 are washed. During the process, the clockwise rotation time and the counterclockwise rotation time of the impeller are different, so that the clothes are turned upside down and the clothes will not be entangled too much.

[0083] The reverse water flow and the normal water flow are operated alternately to achieve the best washing effect and anti-entanglement effect on the clothes. After washing, the stirring blade 2 is placed in the card-connected through hole 32 and the clothes are taken out.

[0084] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
