[0002] The drainage component of a washing machine is an important system that ensures the smooth discharge of sewage after the washing cycle, including the drainage pump usually located at the bottom or side of the washing machine. The drainage pump is the main power source during the washing machine drainage process. Through the drive of the motor, the drainage pump generates strong suction or pressure to quickly discharge the sewage in the washing machine. The motor surface is usually provided with a motor box to prevent dust and other impurities from entering the motor, thereby avoiding damage to the motor and prolonging the service life of the motor.

[0003] However, the motor box is usually installed on the surface of the motor by fasteners such as bolts.

CONTENT OF THE UTILITY MODEL

[0005] The motor box for a washing machine drainage component provided by the present application adopts the following technical solution:

[0007] By adopting the above technical solution, the shell is sleeved on the surface of the coil skeleton, and the surface of the coil skeleton around is abutted against the inner wall of the shell, avoiding the generation of virtual position and the shaking of the coil skeleton left and right in the shell, and the friction block is arranged, the side of the friction block close to the coil skeleton abuts against the surface of the coil skeleton to generate friction force, the coil skeleton cannot slide up and down in the shell under the action of the friction force, and the stator assembly in the shell is firmly fixed in the shell.

[0038] The following description will be made in conjunction with the accompanying drawings as follows: Figures 1-7 The application is further described in detail.

[0039] The embodiment of the application discloses a motor box for a washing machine drainage component.

[0040] Referring to Figures 1-6 A motor box for a washing machine drainage component, comprising a stator assembly 3 and a cavity 1 arranged on both sides of a rotor assembly 2 respectively, the stator assembly 3 comprises a shell 31 sleeved on the surface of a coil skeleton 32, a cavity one 5 is arranged on one side of the inner wall of the shell 31, a heat dissipation groove 33 is arranged on one side of the shell 31, a fixing assembly 4 is arranged in the cavity one 5, the fixing assembly 4 comprises a friction block 41 located in the cavity one 5 and achieving horizontal sliding, the cavity one 5 is matched with the shape of the friction block 41, and the width of the cavity one 5 is greater than that of the friction block 41, a spring one 42 is fixedly connected to the center of one side of the friction block 41 away from the coil skeleton 32, one end of the spring one 42 away from the friction block 41 is fixedly connected to the outer side of the inner cavity of the cavity one 5, and one side of the friction block 41 away from the spring one 42 is in abutment with the surface of the coil skeleton 32, so that the virtual position is avoided.

[0041] A right-angled triangle groove 43 is arranged on the top center of the friction block 41, a sliding groove one 417 in communication with the right-angled triangle groove 43 is arranged on the top of the shell 31 corresponding to the position of the right-angled triangle groove 43, and the right-angled side of the right-angled triangle groove 43 is greater than the width of the sliding groove one 417, a push rod 44 is located in the sliding groove one 417 and achieves vertical sliding, and the surface around the push rod 44 is in abutment with the inner wall around the inner cavity of the sliding groove one 417, the push rod 44 passes through the sliding groove one 417 and is in abutment with the inclined surface of the right-angled triangle groove 43, a connecting block 45 is fixedly connected to one side of the push rod 44, a sliding groove two 46 in communication with the sliding groove one 417 is arranged in the shell 31, the surface of the connecting block 45 is in abutment with the inner wall of the sliding groove two 46, and the height of the sliding groove two 46 is greater than that of the connecting block 45, so that the connecting block 45 can vertically slide in the sliding groove two 46, a spring two 47 is fixedly connected to the bottom center of the connecting block 45, and the bottom of the spring two 47 is fixedly connected to the bottom center of the inner cavity of the sliding groove two 46.

[0042] The shell 31 is sleeved on the surface of the coil skeleton 32, used for protecting the stator assembly 3, and the side surface of the arranged friction block 41 is in abutment with the surface of the coil skeleton 32, and a friction force is generated between them, under the action of the friction force, the coil skeleton 32 cannot shake in the shell 31, and then the shell 31 is fixed on the surface of the coil skeleton 32, so that the stability of the device is provided.

[0043] Furthermore, the outer casing 31 is easy and quick to install and remove. By pushing the push rod 44, the push rod 44 and the connecting block 45 slide down, while the connecting block 45 compresses the second spring 47. The push rod 44 applies a pushing force to the inclined surface of the right-angled triangular groove 43, thereby the friction block 41 will be subjected to a component force in the direction of the cavity 5. Under the action of the force, the friction block 41 slides into the cavity 5, while compressing the first spring 42. As a result, the side of the friction block 41 no longer abuts against the surface of the coil frame 32, and there is no friction between them. Therefore, the outer casing 31 can be fitted onto the surface of the coil frame 32 or removed from the surface of the coil frame 32.

[0044] Reference Figures 3-7 The top of the push rod 44 is flush with the top of the outer casing 31, and the pressing block 48 is fixedly installed on the top of the push rod 44. The top of the outer casing 31 has a groove 49 that communicates with the slide groove 417. When the pressing block 48 is forcefully inserted into the groove 49, its surface abuts against the inner wall of the groove 49. The slide groove 411 is opened on one side of the pressing block 48. The right-angled triangular locking block 410 is located in the slide groove 411, and the three surfaces of the right-angled triangular locking block 410, except for the inclined surface, abut against the inner wall of the slide groove 411. The length of the slide groove 411 is greater than that of the right-angled triangular locking block 410. The length of the right-angled side of 10 allows the right-angled triangular block 410 to slide laterally within the slide groove 411. A spring 412 is fixedly connected to the center of the inner side of the right-angled triangular block 410. The end of the spring 412 away from the right-angled triangular block 410 is fixedly connected to the inner side of the slide groove 411. A slot 415 is provided on one side of the groove 49. When the pressing block 48 is inserted into the groove 49, the right-angled triangular block 410 is engaged in the slot 415, and the top and both sides of the right-angled triangular block 410 abut against the inner wall of the slot 415.

[0045] L-shaped lever 413 includes a horizontal bar 4131, which is fixedly connected to the top of the inner side of the right-angled triangular block 410. A vertical bar 4132 is fixedly connected to the end of the horizontal bar 4131 away from the right-angled triangular block 410. A slide groove 414, which communicates with slide groove three 411, is opened on the top of the pressing block 48. The vertical bar 4132 is located inside slide groove four 414 and its top extends through slide groove four 414 to the outside. The surface of the vertical bar 4132 abuts against the inner wall of slide groove four 414, and the length of slide groove four 414 is greater than the length of vertical bar 4132. A sealing cover 416 is inserted into the top of the inner cavity of slide groove four 414. The sealing cover 416 includes a sealing block 4161 that matches the shape of slide groove four 414, and the height of sealing block 4161 is less than the height of slide groove four 414. A handle 4162 is fixedly connected to the top of sealing block 4161.

[0046] When the shell 31 needs to be installed or disassembled, the push rod 44 needs to be pushed, and only the pressing block 48 needs to be pressed. The pressing block 48 will slide down the push rod 44, and the pressing block 48 is inserted into the groove one 49. The inclined surface of the right-angled triangular clamping block 410 is stressed. It can be known through force decomposition that the right-angled triangular clamping block 410 is subjected to a force in the direction of the sliding groove three 411. Then the right-angled triangular clamping block 410 completely slides into the sliding groove three 411, and the compression spring three 412 is compressed. When the bottom of the pressing block 48 and the bottom of the inner cavity of the groove one 49 abut, the right-angled triangular clamping block 410 is just in the position corresponding to the clamping groove 415. Then the right-angled triangular clamping block 410 rebounds and is clamped in the clamping groove 415 under the action of the spring three 412, so as to limit the pressing block 48 in the groove. It is avoided that the pressing block 48 rebounds to the original position under the action of the spring two 47, so as to avoid the rebound of the push rod 44. Then the pressing block 48 does not need to be pressed by hand all the time. When the hand is released, the pressing block 48 and the push rod 44 also cannot rebound to the original position. The operation is simple and convenient, and the shell 31 is convenient to disassemble and assemble.

[0047] When the shell 31 is installed, the longitudinal rod 4132 is transversely pushed, and the right-angled triangular clamping block 410 is indirectly pushed to slide into the sliding groove three 411. When the right-angled triangular clamping block 410 completely slides into the sliding groove three 411, the pressing block 48 and the push rod 44 rebound to the original position under the action of the spring two 47. Then the pushing force acting on the friction block 41 is removed. The friction block 41 can rebound to the original position under the action of the spring one 42. Then the side of the friction block 41 close to the coil framework 32 again abuts the surface of the coil framework 32 to generate a friction force. Then the stator assembly 3 is fixed in the shell 31, and shaking is avoided.

[0048] The implementation principle of the motor box for the washing machine drainage component in the embodiment of the application is as follows: when the stator assembly 3 is fixed in the shell 31, the pressing block 48 is pressed. The pressing block 48 will slide down the push rod 44, and the pressing block 48 is inserted into the groove one 49. The inclined surface of the right-angled triangular clamping block 410 is stressed. Then the right-angled triangular clamping block 410 completely slides into the sliding groove three 411, and the compression spring three 412 is compressed. When the bottom of the pressing block 48 and the bottom of the inner cavity of the groove one 49 abut, the right-angled triangular clamping block 410 is just in the position corresponding to the clamping groove 415. Then the right-angled triangular clamping block 410 rebounds and is clamped in the clamping groove 415 under the action of the spring three 412, so as to avoid the rebound of the push rod 44. The pushing force of the push rod 44 acting on the inclined surface of the right-angled triangular groove 43 always exists. The friction block 41 always receives a component force in the direction of the cavity one 5, so that the friction block 41 slides into the cavity one 5 under the action of the force, and the spring one 42 is compressed. Then the side of the friction block 41 no longer abuts the surface of the coil framework 32, and there is no friction force between them. Then the shell 31 can be sleeved on the surface of the coil framework 32.

[0049] After installation, the longitudinal rod 4132 is pushed horizontally to indirectly drive the right-angled triangular clamping block 410 to slide into the sliding groove three 411. When the right-angled triangular clamping block 410 is completely slid into the sliding groove three 411, the pressing block 48 and the push rod 44 are bounced back to the original position under the action of the second spring 47, thereby canceling the pushing force on the friction block 41. The friction block 41 can bounce back to the original position under the action of the first spring 42, thereby the side of the friction block 41 close to the coil former 32 again abuts against the surface of the coil former 32 to generate a friction force, thereby the stator assembly 3 is fixed in the shell 31, and shaking is avoided.

[0050] When the shell 31 needs to be disassembled, the same as the installation.

[0051] The above is only an optional embodiment of the present disclosure, and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
