[0002] After the stirring mechanism in the washing device is used for a long time, dirt will accumulate at the bottom of the stirring mechanism, and it is difficult for the user to directly clean the bottom of the stirring mechanism. Therefore, a detachable stirring mechanism has appeared on the market. A radially movable clip is arranged in the center of the stirring mechanism, and a pressing structure is arranged on the upper surface of the stirring mechanism. The clip is locked on the drive shaft by pressing the pressing structure.

[0003] However, the scheme of providing a pressing structure on the upper surface of the stirring mechanism will cause the surface of the stirring mechanism to bulge, and the bulge is easy to entangle the laundry during the washing process, causing deformation and damage to the laundry. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a locking assembly and a washing device, by which the locking assembly can be used to lock and separate the stirring mechanism and the washing device, so that the stirring mechanism can be removed from the washing device for separate cleaning. The disassembly structure is simple and convenient for cleaning dirt.

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

[0007] The rotating disk is hollow inside to form an installation cavity, and at least one engaging tooth is arranged on the inner wall of the installation cavity; a engaging groove is arranged at one end of the driving shaft extending into the installation cavity; when the rotating disk rotates under external force, the engaging tooth rotates into or out of the engaging groove, thereby realizing the locking and disengagement of the engaging tooth and the engaging groove.

[0008] Furthermore, the engaging teeth are spiral teeth, and the engaging grooves are spiral grooves matching the spiral teeth.

[0009] Furthermore, the disassembly and installation portion is a positioning hole on the rotating disk, a retractable positioning pin is provided on the fixed disk, a positioning hole is provided on the rotating disk, and the positioning pin extends into the positioning hole to limit the rotation of the rotating disk.

[0010] Furthermore, a limiting slide groove is arranged on the fixed disk, and a limiting slider is arranged at the bottom of the rotating disk to limit the rotation angle of the rotating disk.

[0011] Furthermore, one end of the limiting slide groove corresponds to the locking position, the other end of the limiting slide groove corresponds to the disengagement position, and the positioning pin is arranged at one end of the locking position.

[0012] Furthermore, it also includes an auxiliary disassembly and assembly tool, which includes at least one pin matching the positioning hole.

[0013] Furthermore, the auxiliary disassembly and assembly tool is separately provided with the rotating disk, and the rotating disk is also provided with an auxiliary disassembly and assembly hole.

[0014] A washing device comprises a washing bin, a stirring mechanism and a driving device, wherein the stirring mechanism is arranged at the bottom or side wall of the washing bin, and the driving device is arranged outside the washing bin. The washing device also comprises a locking assembly, wherein the locking assembly is integrally arranged with the stirring mechanism, and the installation of the stirring mechanism and the driving device is achieved by locking the engaging teeth with the engaging grooves.

[0015] Furthermore, a stirring sleeve is provided at the bottom of the stirring mechanism, and a docking hole communicating with the mounting cavity is provided on the stirring sleeve.

[0016] Furthermore, a shaft neck section is provided on the driving shaft, and the docking hole is non-circular.

[0017] The beneficial effects of adopting the utility model are as follows:

[0018] 1. By providing a stirring mechanism with a locking assembly in the washing chamber, the stirring mechanism can be disassembled and cleaned separately, thereby preventing the bottom of the stirring mechanism from being unable to be cleaned for a long time and breeding bacteria, reducing cleaning dead corners in the washing device, and reducing the risk of cross infection.

[0019] 2. By setting up the locking assembly, when the stirring mechanism needs to be installed, the rotating disk is rotated to lock the engaging teeth and the engaging groove, thereby locking the stirring mechanism on the driving device; when the stirring mechanism needs to be disassembled for separate cleaning, the rotating disk is rotated in the opposite direction to separate the stirring mechanism from the driving device.

DETAILED DESCRIPTION

[0033] 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

[0034] The utility model provides a locking assembly, which is used to lock a stirring mechanism 1 on a driving shaft 2 of a driving device, and the locking assembly comprises a fixed disk 3, a rotating disk 4 and a clamping groove 21; the fixed disk 3 is arranged on the stirring mechanism 1, and the fixed disk 3 comprises a receiving cavity; the rotating disk 4 is rotatably arranged in the receiving cavity, and the rotating disk 4 is hollow to form a mounting cavity 41, and at least one clamping tooth 42 is arranged on the inner wall of the mounting cavity 41; the clamping groove 21 is arranged at one end of the driving shaft 2 extending into the mounting cavity 41; the rotating disk 4 rotates under external force, and the clamping tooth 42 rotates into or out of the clamping groove 21, so as to realize the locking and disengagement of the clamping tooth 42 and the clamping groove 21.

[0035] The fixed disk 3 is fastened to the center of the stirring mechanism 1 by screws. A accommodating cavity for accommodating a rotating disk 4 is provided in the center of the fixed disk 3. The rotating disk 4 is arranged in the accommodating cavity and can rotate relative to the fixed disk 3 under external force. The bottom of the rotating disk 4 extends downward to form an installation cavity 41. The inner wall of the installation cavity 41 is provided with a snap-in tooth 42. Preferably, two snap-in teeth 42 are symmetrically provided on the inner wall of the installation cavity 41; the driving shaft 2 extends into the installation cavity 41 of the rotating disk 4 to be connected with the stirring mechanism 1, and one end of the driving shaft 2 extending into the installation cavity 41 is provided with two snap-in grooves 21 matching the snap-in teeth 42. Multiple groups of snap-in teeth 42 and snap-in grooves 21 are provided to increase the snap-in area between the driving shaft 2 and the installation cavity 41, so that the locking between the driving device and the stirring mechanism 1 can be more stable; of course, only one snap-in tooth 42 can be provided on the inner wall of the installation cavity 41, and only one snap-in groove 21 can be provided on the driving shaft 2, which can also achieve the purpose of fixing the stirring mechanism 1 on the driving shaft 2 of the driving device.

[0036] When installing the stirring mechanism 1, the driving shaft 2 is extended into the installation cavity 41, and the rotating disk 4 is rotated to rotate the engaging teeth 42 into the engaging groove 21. The locking of the engaging teeth 42 and the engaging groove 21 is realized to lock the stirring mechanism 1 with the driving device; when disassembling the stirring mechanism 1, the rotating disk 4 is rotated in the opposite direction to rotate the engaging teeth 42 out of the engaging groove 21. The engaging teeth 42 are disengaged from the engaging groove 21 to realize the release of the stirring mechanism 1 from the driving device, and the stirring mechanism 1 can be removed at this time. By making the engaging teeth 42 move circumferentially with the rotating disk 4, the locking or release of the engaging teeth 42 and the driving shaft 2 is realized. The engaging teeth 42 do not need to move axially or radially along the driving shaft 2. Therefore, there is no need to reserve internal space for the movement of the engaging teeth 42 separately, which reduces the space occupied by the locking assembly inside the stirring mechanism 1, and avoids the locking assembly protruding from the upper surface of the stirring mechanism 1, thereby preventing the laundry from being entangled by the protruding part.

[0037] The stirring mechanism 1 can be a single 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 washings. Example

[0038] Different from the symmetrically arranged engaging teeth 42 in Embodiment 1, the engaging teeth 42 in this embodiment are at least two spiral teeth, and the distance between each spiral tooth and the top of the rotating disk 4 is inconsistent. Accordingly, at least two spiral grooves are arranged on the driving shaft 2.

[0039] When the rotating disk 4 is rotated under external force, the spiral teeth move along the spiral grooves, and the locking and releasing of the stirring mechanism 1 and the driving shaft 2 are realized by the engagement and disengagement of the spiral teeth and the spiral grooves; since the friction between the inclined surfaces is greater, the spiral teeth and the spiral grooves are used as the engaging teeth 42 and the engaging grooves 21, which further increases the friction between the mounting cavity 41 and the driving shaft 2, making the locking between the stirring mechanism 1 and the driving device more stable. Example

[0040] On the basis of Example 1 or Example 2, in order to prevent the rotating disk 4 from reversing and exiting after rotating to the locking position of the engaging teeth 42 and the engaging groove 21, a positioning hole 43 and a positioning latch 31 are respectively provided on the rotating disk 4 and the fixed disk 3. When the engaging teeth 42 rotate into the engaging groove 21, the positioning latch 31 extends into the positioning hole 43 to limit the rotation of the rotating disk 4 and lock the rotating disk 4 and the fixed disk 3 together. The positioning latch 31 is a retractable latch. When the engaging teeth 42 are not rotated into the engaging groove 21, the positioning latch 31 remains in a compressed state under the extrusion of the rotating disk 4; after the engaging teeth 42 are rotated into the engaging groove 21, the positioning hole 43 on the rotating disk 4 rotates to the top of the positioning latch 31, and at this time, the positioning latch 31 extends and extends into the positioning hole 43 to achieve the locking of the rotating disk 4. The positioning hole 43 may be in a circular, square, triangular or other shape, and the positioning pin 31 may extend into the positioning hole. Preferably, the positioning pin 31 realizes a telescopic function through an elastic member 32 , and the elastic member 32 is disposed at the bottom of the positioning pin 31 .

[0041] Furthermore, in order to limit the rotation angle of the rotating disk 4, a limiting slide groove 33 is provided on the fixed disk 3, and a limiting slider 44 is provided at the bottom of the rotating disk 4, and the limiting slider 44 moves in the limiting slide groove 33. The limiting slide groove 33 is arranged along the circumference of the fixed disk 3. When the rotating disk 4 is rotated, the limiting slider 44 rotates with the rotating disk 4. The limiting slide groove 33 limits the rotation angle of the limiting slider 44, thereby limiting the rotation angle of the rotating disk 4, and preventing the engaging tooth 42 from rotating out of the engaging groove 21 due to excessive rotation angle.

[0042] Further, one end of the limiting slide 33 corresponds to the locking position, and the other end of the limiting slide 33 corresponds to the disengaging position. Preferably, the positioning pin 31 is arranged on the fixed disk 3 near the locking position of the limiting slide 33. The locking position is the position of the rotating disk 4 when the engaging teeth 42 and the engaging groove 21 are in a locked state. In the locking position, the positioning hole 43 corresponds to the position of the positioning pin 31, and the positioning pin 31 can extend into the positioning hole 43; the disengaging position is the position of the rotating disk 4 when the engaging teeth 42 and the engaging groove 21 are in a disengaged state. In the disengaging position, the positioning hole 43 and the positioning pin 31 are staggered, and the positioning pin 31 is squeezed by the rotating disk 4 and is in a compressed state; the positioning pin 31 is arranged at one end of the locking position. When the rotating disk 4 rotates to the locking position, the positioning pin 31 corresponds to the positioning hole 43 and extends into the positioning hole 43 to lock the rotating disk 4 and the fixed disk 3.

[0043] When it is necessary to remove the stirring mechanism 1 locked on the driving shaft 2, press the positioning pin 31 from the positioning hole 43 and rotate the rotating disk 4 at the same time. After the rotating disk 4 is rotated to the disengaged position, the stirring mechanism 1 is removed; when it is necessary to install the stirring mechanism 1 on the driving device, rotate the rotating disk 4 to the locking position so that the engaging teeth 42 and the engaging groove 21 are locked, and the positioning pin 31 extends into the positioning hole 43. Example

[0044] On the basis of Example 3, the locking assembly also includes a matching auxiliary disassembly and assembly tool 5, and the auxiliary disassembly and assembly tool 5 includes at least one pin 51 matching the positioning hole 43. The pin 51 extends into the positioning hole 43 of the rotating disk 4 and presses the positioning pin 31 to disengage the positioning pin 31 from the positioning hole 43, so that the rotating disk 4 can rotate relative to the fixed disk 3 under external force, thereby disengaging the engaging tooth 42 from the engaging groove 21, and removing the stirring mechanism 1 from the drive shaft 2.

[0045] The auxiliary disassembly and assembly tool 5 can be designed as an integral part with the rotating disk 4, or can be designed separately from the rotating disk 4. Preferably, the auxiliary disassembly and assembly tool 5 is designed separately from the rotating disk 4 to avoid the problem that when the stirring mechanism 1 is locked and connected with the driving device, the auxiliary disassembly and assembly tool 5 is accidentally touched, causing the rotating disk 4 to reverse to the disengaged position and the stirring mechanism 1 to fall off.

[0046] Specifically, the rotating disk 4 is provided with auxiliary disassembly holes 45 at symmetrical positions of the positioning holes 43. The auxiliary disassembly tool 5 includes a gripping portion, and two pins 51 are provided at the bottom of the gripping portion. The positions of the two pins 51 match the positioning holes 43 and the auxiliary disassembly holes 45 respectively. When the rotating disk 4 needs to be rotated, the two pins 51 of the auxiliary disassembly holes 45 are respectively inserted into the positioning holes 43 and the auxiliary disassembly holes 45 of the rotating disk 4, and the rotating disk 4 is driven to rotate by rotating the gripping portion, thereby realizing the locking or disengagement of the stirring mechanism 1 and the driving shaft 2. Of course, the number of the auxiliary disassembly holes 45 is not limited to one, and multiple holes can also be provided. Example

[0048] The washing bin is used to accommodate laundry, and the stirring mechanism 1 is installed in the washing bin to stir the laundry and washing water. The stirring mechanism 1 is arranged at the bottom and / or side wall of the washing bin, and the driving device is arranged outside the washing bin. The driving shaft 2 extends into the stirring mechanism 1 and is detachably connected to the stirring mechanism 1. The locking assembly is arranged at the central position of the stirring mechanism 1, and the locking assembly is integrally arranged with the stirring mechanism 1. The locking or disengagement of the engaging teeth 42 and the engaging grooves 21 realizes the installation or separation of the stirring mechanism 1, the driving device and the washing bin.

[0049] Furthermore, a stirring sleeve 6 is provided at the bottom of the stirring mechanism 1, and the fixed plate 3 is fastened to the stirring sleeve 6 by screws, thereby realizing a fixed connection between the locking assembly and the stirring mechanism 1; a docking hole 61 connected to the mounting cavity 41 is provided on the stirring sleeve 6, and the drive shaft 2 passes through the stirring sleeve 6 and extends into the locking assembly.

Correspondingly, the drive shaft 2 is provided with a shaft neck section 22, and the driving device drives the stirring mechanism 1 to rotate through the cooperation of the shaft neck section 22 and the docking hole 61; or, the stirring shaft sleeve 6 and the drive shaft 2 are respectively provided with matching spline sleeves and spline shafts, and the stirring mechanism 1 is connected to the driving device by splines.
