Description

Technical Field

[0001] The utility model belongs to the technical field of washing, and particularly relates to a stirring body and a stirring mechanism. Background Art

[0002] A stirring mechanism is usually provided in a washing device to stir the water flow and the laundry, especially in a washing machine, where a stirring mechanism such as a pulsator is used to turn over the laundry and stir the washing water to achieve cleaning of the laundry. When the stirring mechanism turns over the laundry, the laundry is hooked by the stirring mechanism and rotates with the stirring mechanism, thereby turning over the laundry and ensuring that all sides of the laundry can be washed by the washing water.

[0003] However, most of the stirring mechanisms currently available on the market are hard. When stirring the laundry, the hard stirring mechanism and the laundry are constantly rubbed against each other, and the laundry is easily worn. Moreover, when the laundry is entangled between the hard stirring mechanism and the side wall of the washing space, the hard stirring mechanism continues to rotate, which can easily cause the laundry to be deformed or even damaged. In addition, after long-term use, the stirring mechanism is prone to accumulation of dirt at the bottom of the stirring mechanism, the connection between the stirring mechanism and the washing space, and these places are not convenient for users to clean directly. At present, such hard and difficult-to-clean stirring mechanisms are not only easy to damage the laundry, but also easy to harbor dirt and breed bacteria. Summary of the invention

[0004] In view of the above problems, the purpose of the utility model is to provide a stirring body and a stirring mechanism, which can stir the laundry without causing deformation or damage to the laundry, and the stirring mechanism has a simple disassembly structure, which is convenient for separate cleaning after disassembly.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A stirring body comprises a hard part and a deformable part, wherein the deformable part covers the surface of the hard part and contacts with the laundry during washing.

[0007] Furthermore, the deformable portion partially protrudes from the surface of the stirring body to form a stirring portion.

[0008] Furthermore, the hard part is spaced apart at the position of the stirring part, thereby increasing the degree of deformability of the stirring part.

[0009] Furthermore, the stirring part at least includes a first stirring part and a second stirring part, and the first stirring part is higher than the second stirring part.

[0010] Furthermore, friction ribs are arranged on the side wall and / or the surface of the stirring portion.

[0011] Furthermore, ventilation holes are provided on the hard part and the deformable part.

[0012] A driving device is provided, one end of which is connected with a driving shaft.

[0013] A stirring mechanism comprises a stirring body and a driving device, wherein a mounting cavity is centrally arranged at the hard part and the deformable part, the driving shaft sequentially passes through the hard part and the deformable part and is connected to the mounting cavity, and a power transmission mechanism is arranged between the stirring body and the driving device.

[0014] Furthermore, the stirring body and the driving shaft are detachably connected via a connecting assembly, and the connecting assembly includes a slider and a buckle step. The slider is arranged on the stirring body, and the slider can move radially along the driving shaft. A first conical surface is arranged at the end of the slider in contact with the driving shaft; the buckle step is arranged at the end of the driving shaft extending into the mounting cavity; the slider moves radially along the driving shaft under external force to achieve the disengagement or locking of the first conical surface on the buckle step.

[0015] Furthermore, it also includes a slider sleeve, which is fixedly arranged in the installation cavity, and the slider sleeve limits the radial movement of the slider.

[0016] Furthermore, a slider reset member is arranged in the slider sleeve.

[0017] Furthermore, a button is arranged on the top of the installation cavity, and the button can move axially along the driving shaft, and the bottom of the button is a conical surface; the end of the slider facing the button is a second conical surface; the button moves under external force and squeezes the second conical surface to realize the movement of the slider.

[0018] Furthermore, a button reset member is provided at the bottom of the button.

[0019] The beneficial effects of adopting the utility model are as follows:

[0020] 1. By setting the side of the stirring body that contacts the laundry to be flexible and deformable, the friction of the stirring mechanism on the laundry can be reduced during the washing process, thereby reducing the degree of wear on the laundry; and by setting a flexible and deformable stirring part, when the laundry is entangled between the stirring mechanism and the washing space, the stirring part can be deformed to make way for the laundry, thereby preventing the laundry from being pulled, deformed or damaged.

[0021] 2. By providing air holes on the surface of the stirring body, the inner side of the laundry piled and wrapped on the surface of the stirring body can also be exposed to the dry hot air, ensuring that all sides of the laundry can be dried to avoid the phenomenon of local moisture.

[0022] 3. The utility model adopts a connecting assembly including a slider and a buckle assembly to achieve a detachable connection between the stirring body and the driving device. The disassembly structure is simple, and the stirring body can be removed from the driving device without adding a separate disassembly tool, which is convenient for the user to clean the stirring mechanism separately, reduce dirt at the bottom, angle and other positions of the stirring mechanism, and avoid cross infection.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. The orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship usually placed when the application product is used, or the orientation or position relationship commonly understood by those skilled in the art. The terms "set", "open", "install", "connected" and "connected" should be understood in a broad sense. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. And in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Example

[0037] The utility model provides a stirring body, such as Figure 1-6 As shown, the stirring body 1 includes a hard portion 101 and a deformable portion 102. The deformable portion 102 covers the surface of the hard portion 101. The deformable portion 102 contacts the laundry during washing.

[0038] The stirring body 1 can be a separately rotating impeller, or a rotatable inner drum provided with water stirring ribs, or other rotating mechanisms that can stir the washing water and turn over the laundry; the stirring body 1 includes a hard part 101 and a deformable part 102, the deformable part 102 and the hard part 101 are of the same size and shape, the deformable part 102 covers the upper surface of the hard part 101, or the deformable part 102 wraps the entire surface of the hard part 101, the deformable part 102 is fixedly connected to the hard part 101 by screws, rubber coating, etc., or is detachably connected to the hard part 101 by snap-on, etc.; preferably, the deformable part 102 is made of silicone, and the deformable part 102 contacts the laundry during washing, and the laundry rubs against the surface of the flexible and deformable stirring body 1, thereby reducing the wear on the surface of the laundry.

[0039] In order to turn over more laundry and ensure adequate washing, the deformable portion 102 partially protrudes from the surface of the stirring body 1 to form a stirring portion 5, which extends into the laundry and drives the laundry to turn over. The number of stirring portions 5 can be one or more. The side wall and / or surface of the stirring portion 5 is also provided with friction ribs 503, which are used to increase the friction between the stirring body 1 and the laundry, so that the stirring portion 5 is easier to turn over the laundry, and the cleaning power can also be enhanced. By providing a deformable stirring portion 5, when the laundry is entangled between the stirring body 1 and the side wall of the washing space, the stirring portion 5 can be deformed and made way under the pressure of the laundry, thereby avoiding the problem that the laundry is pulled, deformed or damaged due to the rotation of the stirring mechanism.

[0040] Furthermore, in order to increase the deformability of the stirring portion 5, the hard portion 101 is avoided at the position of the stirring portion 5, and the interior of the stirring portion 5 is hollow. When the laundry is entangled between the stirring body 1 and the side wall of the washing space, the stirring portion 5 can be deformed toward the bottom of the stirring body 1 under the pressure of the laundry, thereby increasing the degree to which the stirring portion 5 makes way for the laundry and preventing the laundry from being pulled, deformed or damaged. Example

[0041] On the basis of Example 1, Figure 7 As shown, the stirring part 5 includes a first stirring part 501 and a second stirring part 502, and the first stirring part 501 is higher than the second stirring part 502. During washing, the stirring body 1 rotates under the drive of the driving device, and part of the laundry is wrapped on the first stirring part 501 and rotates with the stirring body 1, thereby realizing the turning of the laundry by the stirring mechanism. By setting the first stirring part 501 higher than the second stirring part 502, the laundry is more easily wrapped on the raised first stirring part 501, and the stirring mechanism is more likely to turn the laundry. Of course, in order to meet various washing needs, according to the size and material of the laundry, more first stirring parts 501 or second stirring parts 502 can also be set.

[0042] Furthermore, in order to stir the laundry accumulated at the bottom or side of the washing space, the side wall or top of the first stirring portion 501 extends beyond the edge of the hard portion 101. Figure 7 The embodiment in which the top of the first stirring part 501 extends out of the edge of the hard part 101 is shown. When the stirring mechanism is arranged on the side wall of the washing space, when the first stirring part 501 rotates with the stirring body 1 to the bottom of the washing space, the laundry accumulated at the bottom can be stirred up by the part extending from the first stirring part 501, thereby realizing the turning over of the laundry accumulated at the bottom of the washing space, and avoiding that some laundry cannot be washed; when the stirring mechanism is arranged at the bottom of the washing space, the first stirring part 501 can stir the laundry accumulated between the side wall of the washing space and the stirring body 1, so that this part of the laundry can also rotate with the stirring body 1 and be fully washed by the washing water. By extending the side wall or the top of the first stirring part 501 out of the edge of the hard part 101, the problem that some laundry cannot be turned over and cannot be fully washed can be avoided. Example

[0043] On the basis of Example 1 or Example 2, a plurality of air holes 6 are provided on the hard part 101 and the deformable part 102. When the washing device has a drying function, dry hot air is introduced into the washing space, and the dry hot air contacts the surface of the laundry, takes away the moisture in the laundry, and then dries the laundry. However, the inner side of the laundry that is partially accumulated and wrapped on the surface of the stirring body 1 cannot directly contact the dry hot air introduced into the washing space. This part of the laundry is accumulated on the surface of the stirring body 1 and blocked above part of the air vents. The dry hot air enters the bottom of the stirring body 1 through the unblocked air holes 6 on the surface of the deformable part 102, and then blows from the blocked air holes 6 to the laundry, and dries the inner side of the laundry accumulated on the air holes 6.

[0044] The air holes 6 are circumferentially arranged at the edge portions of the deformable portion 102 and the hard portion 101, so as to avoid the air holes 6 being completely blocked by the laundry as much as possible, and at least a portion of the air holes 6 can be exposed, so that dry hot air can enter the bottom of the stirring body 1 from the exposed air holes 6 to dry the inner side of the laundry accumulated at the air holes 6.

[0045] By providing air holes 6 on the surface of the stirring body 1, dry hot air can pass through the stirring body 1 to dry the laundry wrapped on the stirring body 1 in all directions, thereby avoiding the phenomenon of partial undried laundry and achieving full drying of the laundry. Example

[0046] The utility model also provides a driving device and a stirring mechanism. A driving shaft 2 is arranged at one end of the driving device.

[0047] A stirring mechanism comprises a driving device and a stirring body as described in any one of the embodiments 1-3, wherein a driving shaft is connected to the driving device, and an installation cavity 103 is centrally arranged between a hard portion 101 and a deformable portion 102; the driving device comprises a driving shaft 2, which passes through the hard portion 101 and the deformable portion 102 in sequence and is then connected to the installation cavity 103; a power transmission mechanism is arranged between the stirring body 1 and the driving device.

[0048] A through hole is provided in the center of the hard part 101 and the deformable part 102 to form an installation cavity 103. The driving shaft 2 of the driving device passes through the through hole on the hard part 101 and the through hole on the deformable part 102 in sequence and is connected to the installation cavity 103, so as to realize the connection between the driving device and the stirring body 1, and realize the driving device driving the stirring body 1 to rotate through the power transmission mechanism. The power transmission mechanism provided between the stirring body 1 and the driving device can be a driving hole provided at the bottom of the stirring body 1 and a journal section on the driving shaft 2, that is, at least one plane is provided on the driving shaft, or a spline groove 3 and a claw plate 4 are provided between the stirring body 1 and the driving device, and the claw plate 4 is clamped in the spline groove 3 so as to realize the driving device driving the stirring body 1 to rotate. Any structure that can transmit the torque of the driving device to the stirring body 1 can be adopted. Example

[0049] Based on Example 4, the stirring body and the driving device are detachably connected through a connecting assembly, such as Figure 2-3 , Figure 8-12 As shown, the connecting component is arranged in the installation cavity 103, and the connecting component includes a slider 7 in the stirring body 1 and a buckling step 201 on the driving shaft 2. The buckling step 201 is arranged at one end of the driving shaft 2 extending into the installation cavity 103. The slider 7 can move radially along the driving shaft 2, and a first conical surface 701 is arranged at the end of the slider 7 that contacts the driving shaft 2.

[0050] The slider 7 at least includes a locking position and a disengaging position. The slider 7 can move between the locking position and the disengaging position along the radial direction of the drive shaft 2 under external force. When the slider 7 is in the locking position, the first conical surface 701 is locked on the buckle step 201 of the drive shaft 2, thereby limiting the axial movement of the stirring body 1, and realizing that the stirring body 1 and the driving device are locked together. At this time, the slider 7 can be restricted in the locking position by elastic parts, buckles and other structures, thereby ensuring the locking of the stirring body 1 and the driving device; when the slider 7 is in the disengaging position, the first conical surface 701 releases the locking of the buckle step 201, and the stirring body 1 can move axially along the drive shaft 2, and the stirring body 1 can be removed at this time. Two sliders 7 arranged opposite to each other are arranged in the stirring body 1, and the first conical surfaces 701 are arranged opposite to each other. The two first conical surfaces 701 are used to realize the locking of the left and right sides to the driving shaft 2. Of course, more sliders 7 can also be arranged according to washing needs.

[0051] The installation cavity 103 is provided with a sleeve 8, which is hollow and has openings at the top and bottom. The drive shaft 2 is inserted into the sleeve 8 and locked by the slider 7. A slider sleeve 9 is provided in the sleeve 8, and the slider 7 moves in the slider sleeve 9. The slider sleeve 9 is used to limit the slider 7 to move only radially along the stirring body 1. Specifically, a limiting step 704 is provided on the inner wall of the slider sleeve 9, and a slider rib 902 is provided on the side of the slider 7 close to the sleeve 8. The slider 7 is limited in the slider sleeve 9 by the cooperation between the limiting step 704 and the slider rib 902 to prevent the slider 7 from falling from the stirring body 1. The bottom of the slider sleeve 9 is fixedly connected to the stirring body 1 by screws or the like, and the slider sleeve 9 and the sleeve 8 are relatively fixed by the structure of the positioning strip 901 and the positioning groove. In order to further reduce the friction between the slider 7 and the slider sleeve 9, a convex strip is provided on the outer wall of the slider 7. When the slider 7 moves radially, only the convex strip contacts the slider sleeve 9, thereby reducing the friction area when the slider 7 moves.

[0052] In order to realize that the slider 7 can automatically return to the locked position after the external force is removed, a slider reset member 10 is provided in the slider sleeve 9. Preferably, the slider reset member 10 is an elastic member, one end of which abuts against the slider 7, and the other end abuts against the inner wall of the slider sleeve 9 or the sleeve 8. When there is no external force, the slider 7 is stationary in the locked position under the action of the elastic member; when the slider 7 moves to the disengaged position under the external force, the slider 7 compresses the elastic member, and after the external force is removed, the slider 7 is reset to the locked position under the elastic force of the elastic member.

[0053] When the stirring body 1 needs to be disassembled, a tool can be used to extend into the installation cavity 103 from the top of the sleeve 8, and the slider 7 can be pushed to the disengaged position on both sides to disengage the drive shaft 2 from the locking of the sliders 7 on both sides, so that the stirring body 1 can be removed. After the tool is removed and the external force is released, the slider 7 automatically returns to the locked position; when the stirring body 1 needs to be installed, the slider 7 is pushed to the disengaged position with a tool, and the stirring body 1 is simultaneously sleeved on the drive shaft 2, and then the tool is taken out and the external force is released, so that the slider 7 is reset to the locked position and the stirring body 1 is locked on the drive device. Example

[0054] On the basis of Example 5, a button 11 is provided at the top of the sleeve 8, and the button 11 can move axially along the sleeve 8. The bottom of the button 11 is a conical surface, and accordingly, the end of the slider 7 facing the button 11 is a second conical surface 702. By pressing the button 11 to move it downward, the conical surface at the bottom of the button 11 squeezes the second conical surface 702 on the slider 7, so that the slider 7 moves, and the slider 7 moves from the locking position to the disengaging position.

[0055] The sleeve 8 is provided with an abutment portion 801, and the bottom of the key 11 passes through the abutment portion 801 and contacts the slider 7. An annular groove 1101 is opened at the bottom of the key 11. A gasket 13 is provided in the annular groove 1101, and the gasket 13 abuts between the key 11 and the abutment portion 801, so that the key 11 is limited in the sleeve 8 to prevent the key 11 from falling from the top opening of the sleeve 8.

[0056] Furthermore, a button reset member 12 is provided between the abutment portion 801 and the button 11. The button reset member 12 is preferably an elastic member, which is sleeved on the conical surface at the bottom of the button 11. One end of the elastic member abuts against the abutment portion 801, and the other end abuts against the top of the button 11. After the external force on the button 11 is released, the button 11 is reset and lifted up under the elastic force of the elastic member, thereby releasing the squeezing of the conical surface at the bottom of the button 11 on the slider 7, so that the slider 7 can be moved to the locking position. Example

[0057] like Fig. 9 As shown, on the basis of Embodiment 5 or 6, a third conical surface 703 is provided at the bottom end of the slider 7. When the stirring body 1 is installed, the third conical surface 703 first contacts the buckle step 201, and the buckle step 201 squeezes the third conical surface 703 to move the slider 7 from the locking position to the disengaging position. As the stirring body 1 moves downward, the buckle step 201 begins to contact the second conical surface 702. At this time, the slider 7 can move to the locking position, and the second conical surface 702 is locked on the buckle step 201, so as to achieve the locking of the stirring body 1 and the driving device. By providing the third conical surface 703 at the bottom end of the slider 7, it is possible to move the slider 7 without applying a special external force during installation, that is, it is no longer necessary to use a tool or press the button 11 separately, thereby improving the convenience during installation.
