[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A replaceable washing machine knob assembly includes a control panel 1 and a knob body 2. The control panel 1 has a connector 3, into which the knob body 2 can be inserted. The bottom of the knob body 2 has a latch 4, which is a frustum-shaped structure wider at the top and narrower at the bottom. A control end 5 is located at the bottom of the latch 4. The controller switch inside the control panel 1 is located at the innermost part of the knob body 2. When the bottom of the knob body 2 is inserted into the connector 3, the control end 5 engages with the controller switch. When the knob body 2 is rotated, the control end 5 rotates accordingly, thus controlling the controller switch. The control panel 1 has receiving grooves 6 on both sides of the knob body 2, which are connected to the knob body 2. A locking block 7 slides inside the receiving groove 6. The side is a sloping conical structure that fits the outer surface of the card head 4. The top of the receiving groove 6 is provided with a through slot 8. The top of the card block 7 extends out of the outside of the receiving groove 6 through the through slot 8 and is fixedly connected to a slide rod 9. The user can slide the card block 7 inside the receiving groove 6 by sliding the slide rod 9. The through slot 8 restricts the sliding stroke of the slide rod 9. When the slide rod 9 is slid to the front end of the through slot 8, the front end of the card block 7 will slide out of the outside of the receiving groove 6 and extend into the insertion hole 3. When the slide rod 9 is slid to the rear end of the through slot 8, the front end of the card block 7 will move completely into the inside of the receiving groove 6. A spring 10 is also provided inside the receiving groove 6. The two ends of the spring 10 abut against the rear end of the card block 7 and the inner wall of the receiving groove 6. The spring 10 is in a compressed state and can always generate an elastic force to move the card block 7 towards the front of the receiving groove 6.

[0022] Under the elastic force of spring 10, the front end of the locking block 7 will always extend beyond the outer side of the receiving groove 6 and into the insertion hole 3. When the knob body 2 is inserted into the insertion hole 3, the locking head 4 located at the bottom of the knob body 2 will also extend downward into the insertion hole 3. During this process, the locking head 4 will abut against the front end of the locking block 7 and exert a pushing force on the locking block 7 to move inward toward the receiving groove 6. Under this pushing action, the locking block 7 will overcome the elastic force of spring 10 and move inward toward the receiving groove 6. When the knob body 2 is inserted into the innermost part of the insertion hole 3, the control end 5 will engage with the internal controller of the control panel 1. At the same time, the locking head 4 will move completely below the locking block 7. At this time, the locking head 4 will no longer push the locking block 7 towards the inside of the receiving groove 6. Thus, the locking block 7 will move outward from the receiving groove 6 again under the elastic force of the spring 10. When the front end of the locking block 7 extends into the insertion hole 3, it can lock the locking head 4 below it. At this time, the knob body 2 will engage with the internal controller of the control panel 1. The knob body 2 will be unable to be pulled out of the plug hole 3 due to the restraint of the locking head 4 and the locking block 7. This allows the knob body 2 to be installed in the plug hole 3 without restricting its rotation. When it is necessary to remove the knob body 2 from the plug hole 3, the user slides the slider 9 to the rear end of the through slot 8. At this time, the locking block 7 will move to the innermost end of the receiving groove 6 under the action of the slider 9, and its front end will no longer lock the locking head 4. The user can then directly pull the knob body 2 out of the plug hole 3, thus completing the disassembly of the knob body 2. In summary, the user can directly insert the knob body 2 into the plug hole 3 to complete the installation of the knob body 2. In addition, the user can directly pull the knob body 2 out of the plug hole 3 by sliding the slider 9 to the rear end of the through slot 8. Therefore, the disassembly and assembly of the knob body 2 can be performed conveniently and quickly, which facilitates the replacement of the worn and deformed knob body 2 in the future.

[0023] For further details, please refer to Figure 1 and Figure 2 A lever 11 is fixedly connected to the top of the slider 9. The lever 11 has a flat structure and its surface is provided with anti-slip texture, which makes it easy for the user to move the slider 9 horizontally by hand.

[0024] For further details, please refer to Figure 2 The control panel 1 is provided with a limiting ring 12 around the plug hole 3. The top edge of the knob body 2 is provided with a collar 13. When the knob body 2 is inserted into the plug hole 3, the collar 13 will just be engaged with the outside of the limiting ring 12. At this time, the mutually engaged limiting ring 12 and collar 13 can restrict the knob body 2 from shaking inside the plug hole 3, so that the knob body 2 can be stably held in the plug hole 3 in a vertical state.

[0025] For further details, please refer to Figure 1-4The knob body 2 has a handle 14 at the top. The handle 14 has a rounded edge. When the knob body 2 is installed inside the plug hole 3, the handle 14 is exposed above the plug hole 3. The user can easily rotate the knob body 2 by holding the handle 14.

[0026] Furthermore, the knob body 2 is made of ABS plastic, which is lightweight, low-cost, easy to process and mold, and also has good heat resistance and strength.

[0027] For further details, please refer to Figure 1-4 A reinforcing rib 15 connects the control end 5 and the card head 4. The reinforcing rib 15 can support the control end 5 and prevent it from tilting or deforming, thus ensuring that the control end 5 can be smoothly engaged with the controller switch.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
