[0040] In existing washing machine designs, the door magnetic switch is typically mounted to the front panel using screws. This mounting method has significant drawbacks:

[0041] Increased costs and reduced efficiency: The screw fastening process involves additional parts (screws) and assembly time, which leads to increased material and labor costs, and the installation is inconvenient and inefficient.

[0042] Risk of damage and functional failure: During the tightening of the screws, the magnetic door switch body is susceptible to damage from mechanical stress or impact, which may lead to quality problems such as failure of the cover opening detection alarm.

[0043] Therefore, the existing door magnetic switch installation method has prominent problems such as inconvenient operation and low reliability.

[0044] This application provides a washing machine front rack to solve the problem of inconvenient installation of the magnetic door switch in existing washing machines. The following will be discussed in conjunction with the attached... Figure 1-5 Please provide an explanation.

[0045] The washing machine rack provided in this embodiment of the application is referenced. Figure 1 , Figure 2 and Figure 3 As shown, it includes a panel 100, a snap-fit ​​connector 110, a guide post 120, and a magnetic door switch 200; the snap-fit ​​connector 110 is disposed on the panel 100, the guide post 120 is disposed on the panel 100, and the magnetic door switch 200 is provided with a through hole 210. When the magnetic door switch 200 is installed on the panel 100, the guide post 120 passes through the through hole 210, and the magnetic door switch 200 is snapped into the snap-fit ​​connector 110.

[0046] In this embodiment, the panel 100 is a plate-shaped component that forms the bearing surface of the top of the washing machine. The snap-fit ​​component 110 is pre-fixed or integrated onto the panel 100. The snap-fit ​​component 110 may include one or more elastic hooks or claws. These elastic structures can deform when subjected to a pushing force in a certain direction and return to their original shape when the pushing force disappears, thus playing a locking role. The number and position of the snap-fit ​​components 110 can be arranged according to the installation requirements of the door magnetic switch 200.

[0047] One or more guide posts 120 are provided on the panel 100, and the guide posts 120 can be arranged perpendicular to the surface of the panel 100. The diameter of the guide post 120 matches the diameter of the pre-set through hole 210 on the magnetic door switch 200, or the diameter of the guide post 120 is slightly smaller than the diameter of the through hole 210 to allow it to be inserted. The function of the guide post 120 is to provide a precise guiding path for each switch.

[0048] During installation, the user can align the magnetic door switch 200 with the guide post 120 and gently push it downwards or in the designated direction. Due to the presence of the guide post 120, the magnetic door switch 200 is precisely guided, aligning its mounting hole 210 with the guide post 120, avoiding deviations that may occur with manual alignment and achieving precise pre-positioning. Continuing to apply pressure, when the magnetic door switch 200 moves to the predetermined position, its edge or a specific structure will contact the latching member 110. At this time, the elastic structure of the latching member 110 deforms. After the magnetic door switch 200 is fully in place, the elastic structure returns to its original state, and its hook or claw will firmly engage with the corresponding structure of the magnetic door switch 200, completing instantaneous locking. The entire installation process is quick and requires no tools.

[0049] Compared to traditional screw fastening, the snap-fit ​​connection simplifies the installation process and improves efficiency. The cooperation between the guide post 120 and the through hole 210 ensures that the magnetic door switch 200 can be accurately guided to the correct position from the initial installation stage, avoiding the hassle of repeated adjustments due to manual misalignment. Since no large tightening torque is required, it also avoids accidental squeezing or impact damage to the magnetic door switch 200 body or panel 100 that may occur when tightening screws, thus ensuring long-term functional stability and effectively reducing the probability of quality problems such as cover opening detection failure and false alarms caused by installation issues.

[0050] In one optional implementation, combined with Figure 2 and Figure 4 As shown, the end of the guide post 120 is provided with a first guide slope 121 that mates with the through hole 210.

[0051] For example, the first guide ramp 121 can be a conical surface or a small-angle beveled section. The first guide surface is located at the top of the guide post 120, corresponding to the entrance edge of the through hole 210 of the magnetic door switch 200. When the magnetic door switch 200 begins to align with the guide post 120, the edge of the through hole 210 first contacts the higher part of the ramp of the guide post 120. As the operator applies a slight pushing force, the ramp forces the edge of the through hole 210 to slide downwards along the ramp and automatically align with the central axis of the guide post 120, improving the smoothness and convenience of installation and ensuring the accuracy of the final installation position of the magnetic door switch 200.

[0052] In one optional implementation, combined with Figure 2 and Figure 4 As shown, the guide post 120 is integrally formed with the panel 100. For example, the guide post 120 can be integrally injection molded with the panel 100, ensuring that even if the door magnetic switch 200 is subjected to a certain external force (such as a slight impact when opening and closing the door) during subsequent use, the guide post 120 will not become loose or damaged. This greatly enhances the structural stability of the guide post 120, ensures the reliability and consistency of the installation of the door magnetic switch 200, and also significantly simplifies the production process and reduces manufacturing costs.

[0053] In one optional implementation, combined with Figure 2 and Figure 4 As shown, the panel 100 is provided with a support block 130, the door magnetic switch 200 is engaged with the snap-fit ​​component 110, and the door magnetic switch 200 abuts against the support block 130.

[0054] In this embodiment, when the magnetic door switch 200 is guided by the guide post 120 and pushed towards the latching member 110 for latching, the bottom of the switch simultaneously contacts the support block 130. As the latching process completes, the magnetic door switch 200 is held in place by the support block 130, with a specific area at the bottom of the magnetic door switch 200 in close contact with the upper surface of the support block 130. At this time, the position of the magnetic door switch 200 in the direction perpendicular to the panel 100, i.e., the height direction, is accurately limited by the support block 130 and the latching member 110. The normal operation of the magnetic door switch 200 depends on maintaining a precise distance between it and the door cover (or internal magnet). If the switch is installed too high or too low, it may lead to inaccurate detection signals, false triggering, or failure to trigger. Precise control of the installation height via the support block 130 ensures the functional reliability of the magnetic door switch 200.

[0055] Optionally, the number of support blocks 130 can be expanded to multiple to provide more stable support. At the same time, the support blocks 130 can also be manufactured by integral molding with the panel 100, for example, by using injection molding, thereby eliminating subsequent assembly steps.

[0056] In one optional implementation, combined with Figure 2 and Figure 4 As shown, the washing machine rack also includes a mounting box 300, which is disposed on the panel 100 and forms an installation space. The door magnetic switch 200 is installed in the installation space.

[0057] In this embodiment, the mounting box 300 can be a separate structure or a structure that partially contacts the panel 100. It is disposed on the panel 100, and its position corresponds to the mounting area of ​​the door magnetic switch 200. The mounting box 300 forms a closed or semi-closed mounting space to accommodate the door magnetic switch 200. This prevents the door magnetic switch 200 from being damaged by accidental collisions, scratches, or squeezing during transportation, handling, or use, thereby greatly improving the reliability of the door magnetic switch 200 and even the entire washing machine, and reducing the risk of the lid opening detection function failing due to switch damage.

[0058] In one optional implementation, combined with Figure 1 , Figure 2 and Figure 5 The panel 100 shown has a retrieval opening 140 in the middle, and a splash guard 150 is provided around the retrieval opening 140. The mounting box 300 is located on the side of the splash guard 150 away from the retrieval opening 140.

[0059] In this embodiment, by providing a splash guard 150 and positioning the mounting box 300 on the side of the splash guard 150 away from the loading port 140, the possibility of water splashing into the mounting box 300 from the loading port 140 during the washing machine's spin-drying process is further reduced. This ensures the operational stability of the door magnetic switch 200 and reduces the risk of short circuits, corrosion, or malfunctions caused by moisture intrusion.

[0060] In one optional implementation, combined with Figure 2 and Figure 4 As shown, the mounting box 300 includes multiple side plates 310 connected in sequence. The multiple side plates 310 surround to form an installation space, and the side plates 310 have wire holes 311 for allowing wires and signal lines to pass through the mounting box 300 and connect to the sensing part (such as Hall element) of the door magnetic switch 200, or to an external circuit board.

[0061] In an alternative embodiment, the mounting box 300 is provided with a cover (not shown) that can be opened and closed in the mounting space.

[0062] With the cover closed, it provides an additional layer of physical protection. This not only better protects against dust, moisture, and splashes, but also helps prevent accidental impacts from external hard objects to the magnetic door switch 200, improving its durability and operational reliability. When the magnetic door switch 200 needs replacement, repair, or adjustment, maintenance personnel can directly access the switch without disassembling the entire mounting box 300; they can simply open the cover. This enhances the ease of maintenance and production assembly efficiency of the magnetic door switch 200.

[0063] In one optional implementation, combined with Figure 2 and Figure 4 As shown, a reinforcing rib 312 is provided on the side of the side plate 310 facing the door magnetic switch 200. When the door magnetic switch 200 is engaged with the snap-fit ​​component 110, the door magnetic switch 200 abuts against the reinforcing rib 312.

[0064] In this embodiment, the reinforcing rib 312 significantly improves the local stiffness of the side plate 310 near the mounting area of ​​the magnetic door switch 200. When the magnetic door switch 200 is snapped into place and abuts against the reinforcing rib 312, the reinforcing rib 312 provides a more solid and reliable support point, preventing the side plate 310 from undergoing excessive elastic deformation or vibration in this area due to stress. This makes the installation of the magnetic door switch 200 more stable, reducing the possibility of the magnetic door switch 200 becoming loose or shifting due to vibrations generated during the operation of the washing machine, and ensuring the long-term reliability of its function.

[0065] In addition, the reinforcing rib 312 not only provides structural support, but also controls the installation gap of the magnetic door switch 200 in a specific direction. After the magnetic door switch 200 is snapped into place, its edge presses against the reinforcing rib 312. The thickness of the reinforcing rib 312 directly determines the position of the magnetic door switch 200 relative to the side plate 310, thus forming a specific installation gap.

[0066] During the mold design and manufacturing stage, engineers can precisely set the required installation gap of the door magnetic switch 200 by adjusting the thickness of the reinforcing rib 312. Adjusting the thickness of the reinforcing rib 312 on the mold is much simpler and faster than redesigning or modifying the dimensions of the entire side plate 310.

[0067] In one optional implementation, combined with Figure 2 and Figure 4 As shown, the reinforcing rib 312 is provided with a second guide slope 313 that cooperates with the magnetic door switch 200. This guide slope is used to guide the installation direction and assist in positioning during the installation of the magnetic door switch 200, thereby reducing the installation difficulty of the magnetic door switch 200 and improving the convenience, accuracy and efficiency of the installation.

[0068] In one optional embodiment, there can be multiple reinforcing ribs 312, and the multiple reinforcing ribs 312 are spaced apart to ensure uniform installation gaps.

[0069] In one optional implementation, combined with Figure 2 and Figure 3 As shown, the magnetic door switch 200 is provided with a protrusion 220 and two snap-fit ​​pieces 110, which are respectively snapped onto the protrusions 220 on both sides of the magnetic door switch 200.

[0070] Once the clip is engaged, a certain locking force can be formed between the protrusion 220 and the clip 110. This structural connection method can effectively resist the vibration and impact generated during the operation of the washing machine, prevent the door magnetic switch 200 from shifting or falling off due to loosening, ensure the stability of long-term use, and realize a fast, accurate and stable installation solution.

[0071] In one optional implementation, combined with Figure 2 and Figure 4 As shown, the snap-fit ​​component 110 and the side plate 310 are integrally formed, which simplifies the manufacturing process and improves the structural strength of the snap-fit ​​joint, ensuring that the snap-fit ​​structure has a higher load-bearing capacity and a longer service life, thereby improving the installation stability of the door magnetic switch 200.

[0072] The washing machine rack provided in this embodiment includes a panel 100, a snap-fit ​​component 110, a guide post 120, and a magnetic door switch 200. The snap-fit ​​component 110 and the guide post 120 are both disposed on the panel 100. The magnetic door switch 200 has a through hole 210. When the magnetic door switch 200 is installed on the panel 100, the guide post 120 passes through the through hole 210, and the magnetic door switch 200 is snapped into place with the snap-fit ​​component 110. Compared to the traditional screw fixing method, this embodiment achieves precise pre-positioning of the magnetic door switch 200 through the cooperation of the guide post 120 and the through hole 210, and completes instantaneous locking by the elastic snap-fit ​​of the snap-fit ​​component 110, significantly improving installation efficiency and reducing operational complexity, thus enhancing the ease of installation of the magnetic door switch 200.

[0073] Secondly, this application also provides a pulsator washing machine, which includes a cabinet and a washing machine rack as described in the above embodiment, with the washing machine rack covering the cabinet.

[0074] It is understood that the washing machine rack in this embodiment has the beneficial effects of the above embodiments, and the pulsator washing machine has the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this embodiment will not repeat it.

[0075] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application.
