[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0026] See Figures 1-5 An electrical box for an automatic push-pull door lock assembly of a dishwasher includes an electrical box body 2 with an electrical compartment 1. The electrical box body 2 is provided with a push rod 3, a driver 4, and a circuit board 5. The driver 4 is connected to the push rod 3 to drive the push rod 3 to extend and retract. The electrical compartment 1 is located on one side of the push rod 3. The electrical compartment 1 is provided with a switch assembly 6 for detecting the extension and retraction position of the push rod 3. The electrical compartment 1 is arranged along the extension and retraction length direction of the push rod 3 and is adapted to the length of the circuit board 5. The driver 4, the switch assembly 6, and the circuit board 5 are electrically connected.

[0027] In this embodiment, the switch assembly 6 includes a reset switch 7, a maximum travel switch 8, and a door control switch 21. The reset switch 7, maximum travel switch 8, and door control switch 21 are all microswitches. Each microswitch has a corresponding socket on the circuit board 5, and the pins of each microswitch are inserted into the sockets on the circuit board 5, forming an electrical connection between each microswitch and the circuit board 5. This design allows for accurate detection of the extension / retraction position of the push rod 3, thereby ensuring reliable operation of the dishwasher's automatic sliding door. This design not only improves the reliability of the dishwasher's automatic sliding door but also facilitates installation and maintenance.

[0028] In this embodiment, the push rod 3 triggers a signal through the switch assembly 6 during its extension and retraction movement, thereby achieving position detection. Secondly, to ensure the accuracy of the detection, the electrical compartment 1 is arranged along the extension and retraction direction of the push rod 3 and is adapted to the length of the circuit board 5, ensuring that the circuit board 5 can effectively connect various electronic components, achieving a compact structure and reasonable layout.

[0029] In this embodiment, a maximum travel switch 8 is provided on the electrical compartment 1 at the extended position of the push rod 3, and a reset switch 7 is provided on the electrical compartment 1 at the retracted position of the push rod 3. The door control switch 21 is used to detect whether the dishwasher door is closed on the dishwasher.

[0030] The electrical compartment 1 is provided with a rotating pressure block 11 on the side corresponding to the switch assembly 6. During the extension and retraction movement of the push rod 3, the switch assembly 6 is triggered by the pressure block 11.

[0031] The design of the electrical compartment 1, combined with the placement of the pressure block 11, ensures that the push rod 3 effectively contacts the pressure block 11 during its extension and retraction, thereby triggering the switch assembly 6 and detecting the position of the push rod 3. This design ensures that the movement state of the push rod 3 can be monitored in real time, improving the automation and security of the dishwasher's push-pull door lock. This solution effectively solves the problem of accurately triggering the microswitch during the extension and retraction of the push rod 3, thus enhancing the functionality and reliability of the equipment.

[0032] Specifically, during the extension and retraction of the push rod 3, it pushes the pressure block 11 to rotate, thereby triggering the switch assembly 6. When the push rod 3 disengages from the pressure block 11, the pressure block 11 returns to its original position under the action of the elastic element, and the switch assembly 6 also resets accordingly. As a preferred embodiment, the pressure block 11 can be made of a wear-resistant material to improve its service life and reliability.

[0033] In this embodiment, the pressure block 11 includes a first pressure block 9 disposed on one side of the reset switch 7 and a second pressure block 10 disposed on one side of the maximum travel switch 8.

[0034] In this embodiment, the first pressure block 9 and the second pressure block 10 are both rotatably mounted on the electrical compartment 1. The push rod 3 is provided with a protrusion 22, a sliding groove, and a slider 23 that is slidably mounted on the sliding groove. The electrical compartment 1 is provided with a movable cavity on the side corresponding to the door control switch 21, and a compression spring 25 and a movable block 24 that are elastically mounted on the movable cavity. One end of the compression spring 25 acts elastically on the inner side of the movable cavity, and the other end of the compression spring 25 acts elastically on the movable block 24.

[0035] In this embodiment, since the electrical compartment 1 is arranged along the telescopic length direction of the push rod 3, the movable block 24 has the same telescopic movement direction as the push rod 3; the slider 23 is arranged on the push rod 3 and also has the same telescopic movement direction as the push rod 3.

[0036] When push rod 3 extends, and protrusion 22 is positioned between reset switch 7 and maximum travel switch 8, reset switch 7, maximum travel switch 8, and door control switch 21 are all in the open state. Figure 2 As shown.

[0037] When push rod 3 extends, protrusion 22 contacts the second pressure block 10, causing the second pressure block 10 to rotate toward the maximum travel switch 8, thereby triggering the maximum travel switch 8 to close. Meanwhile, reset switch 7 and door control switch 21 are both in the open state. The first pressure block 9 is pushed open by the spring of reset switch 7 (reset switch 7 is in the open state), and compression spring 25 releases its force, driving movable block 24 to move along the extension direction of push rod 3. Door control switch 21 is in the open state. Figure 3 As shown.

[0038] When push rod 3 retracts into the main body 2 of the appliance box, and protrusion 22 is in the reset switch 7 position, protrusion 22 contacts the first pressure block 9, causing the first pressure block 9 to rotate toward the reset switch 7, and the reset switch 7 is in the closed state. The spring of the maximum travel switch 8 pops open the second pressure block 10, and the maximum travel switch 8 is in the open state. If the dishwasher door is fastened to push rod 3, the lock seat 26 of the dishwasher door triggers slider 23 to move toward movable block 24, compression spring 25 is in the compressed state, movable block 24 presses against compression spring 25 and causes door control switch 21 to be in the closed state. Figure 4 As shown.

[0039] When the dishwasher door lock seat 26 disengages from the push rod 3, the compression spring 25 releases its elastic force to push open the movable block 24, and the movable block 24 pushes open the slider 23, so that the door control switch 21 is in the off state.

[0040] The electrical compartment 1 has a notch at the contact point between the movable block 24 and the slider 23.

[0041] The electrical compartment 1 has an avoidance notch 12 on one side corresponding to the rotation of the push rod 3 triggering the pressure block 11.

[0042] On one side of the electrical compartment 1, there are clearance notches 12 corresponding to the first pressure block 9 and the second pressure block 10. When the push rod 3 disengages from the first pressure block 9 or the second pressure block 10 during movement, the clearance notches 12 provide space for the pressure block 11 to be popped open by the micro switch spring, allowing the pressure block 11 to rotate smoothly and avoiding interference. In addition, by setting the clearance notches 12, it is ensured that the push rod 3 will not be obstructed when contacting the first pressure block 9 or the second pressure block 10, thereby improving the reliability and stability of the push-pull door lock assembly.

[0043] The electrical compartment 1 is equipped with a support block 17, which has a positioning notch 18. The circuit board 5 is supported on the positioning notch 18, and the left and right sides of the circuit board 5 are limited between the positioning notch 18 and the inner side of the electrical compartment 1; the front and rear ends of the circuit board 5 are limited between the front and rear inner sides of the electrical compartment 1. Therefore, the circuit board 5 can remain fixed within the electrical compartment 1, preventing displacement due to vibration or external force, thereby improving the reliability and service life of the dishwasher's automatic push-pull door lock assembly. Specifically, the design of the support block 17 and the positioning notch 18 ensures the stability of the circuit board 5 within the electrical compartment 1, guaranteeing the stability of the electrical connection and the normal operation of the circuit.

[0044] The electrical compartment 1 is provided with a terminal block 13 for electrical connection with the circuit board 5, and the electrical compartment 1 is provided with a lead wire opening slot 14 for leading out the lead wire of the terminal block 13.

[0045] The electrical compartment 1 is equipped with terminal blocks 13 and lead wire slots 14. The terminal blocks 13 enable electrical connection between the circuit board 5 and the dishwasher's main control circuit board, while the lead wires from the terminal blocks 13 are led out through the lead wire slots 14. The cooperation of these technical features solves the problem of electrical connection between the circuit board 5 and the dishwasher's main control circuit board, ensuring that the electrical components in the electrical compartment 1 can function normally.

[0046] The terminal block 13 can use standard electrical connection devices, such as screw-type terminal blocks or spring-loaded terminal blocks, to ensure the reliability and stability of the electrical connection. The lead-out slot 14 can be designed in different shapes and sizes to accommodate different types of terminal blocks 13 and leads. Furthermore, the edges of the lead-out slot 14 can be equipped with protective devices, such as rubber or plastic sleeves, to prevent the leads from being worn or damaged during use. In a preferred embodiment, the terminal block 13 can be fixed to the inner bottom wall of the electrical compartment 1, while the lead-out slot 14 can extend through to one outer side of the electrical compartment 1, allowing for a neater arrangement of the leads and reducing interference between them.

[0047] The lead wire opening groove 14 is provided with limiting blocks 15 extending along the inner side of the electrical compartment 1 on both sides; the terminal block 13 is limited and installed between the limiting blocks 15 on both sides of the lead wire opening groove 14.

[0048] The terminal block 13 is stably fixed by the limiting block 15, preventing loosening due to vibration or other external forces and ensuring the reliability of the electrical connection. Meanwhile, the design of the lead wire slot 14 allows for smooth lead wire routing, improving the overall structure's rationality and practicality. Through the combination of these technical features, the problems of fixing the terminal block 13 within the electrical compartment 1 and leading wire routing are solved, improving the overall performance and stability of the dishwasher's automatic push-pull door lock assembly.

[0049] The electrical compartment 1 is fixedly mounted on the electrical box body 2, and the electrical compartment 1 and the electrical box body 2 are configured as an inseparable whole; or, the electrical compartment 1 and the electrical box body 2 are separately configured, and the electrical compartment 1 is detachably mounted on the electrical box body 2.

[0050] The electrical compartment 1 is fixedly mounted on the electrical box body 2. The electrical compartment 1 and the electrical box body 2 are designed as an inseparable whole, which ensures a stable connection between the electrical compartment 1 and the electrical box body 2 and reduces the problem of loosening or falling off due to vibration or external force.

[0051] The electrical compartment 1 and the electrical box body 2 are separate units. The electrical compartment 1 is detachably installed on the electrical box body 2, making maintenance or replacement of the electrical compartment more convenient, without needing to replace the entire electrical box body 2, thus saving maintenance costs. These two different installation methods can flexibly address different usage needs and maintenance requirements, thereby solving the problem of fixed connection or separate installation between the electrical compartment 1 and the electrical box body 2.

[0052] Specifically, the electrical box body 2 can be injection molded to form the electrical compartment 1, ensuring that the electrical compartment 1 and the electrical box body 2 form an inseparable integrated design, providing a stable structure and avoiding loosening or detachment caused by external forces or vibrations during use. On the other hand, the electrical compartment 1 is mounted on another control box, which is connected to the electrical box body 2 via clips or similar means. This design allows users to easily remove the electrical compartment 1 without replacing the entire electrical box body 2 when maintenance or replacement is needed, thereby reducing maintenance costs and improving maintenance efficiency. As a preferred embodiment, the detachable installation of the electrical compartment 1 can employ a quick-release structure, such as using spring fasteners or quick-locking devices, making the disassembly process simpler and faster.

[0053] The push rod 3 is provided with an elastic locking hook 16 for engaging with the dishwasher door. When the dishwasher door is engaged with the push rod 3 via the elastic locking hook 16, the driver 4 drives the push rod 3 to automatically open and close the dishwasher door.

[0054] In this embodiment, the dishwasher door is provided with a lock seat 26, which has a fastening hole. A tension spring is provided on the push rod 3, with one end of the tension spring fixed to the push rod 3 and the other end connected to the elastic hook 16. The elastic hook 16 is rotatably mounted on the push rod 3. The lock seat 26 has a guide slope. When the fastening hole of the lock seat 26 is engaged with the elastic hook 16, the guide slope of the lock seat 26 causes the elastic hook 16 to rotate, and the lock seat 26 moves towards the inside of the push rod 3. When the fastening hole is correspondingly set with the elastic hook 16, the elastic hook 16 is reset and elastically engaged in the fastening hole under the action of the tension spring. When the lock seat 26 is disengaged from the elastic hook 16 under the action of external force, the guide slope of the lock seat 26 causes the elastic hook 16 to rotate, and the lock seat 26 moves towards the outside of the push rod 3. When the fastening hole of the lock seat 26 is completely disengaged from the elastic hook 16, the elastic hook 16 is reset under the action of the tension spring.

[0055] The electrical box body 2 is provided with a transmission component 19 and a mechanical transmission chamber 20 for accommodating and installing the transmission component 19. The mechanical transmission chamber 20 is located on one side of the push rod 3 and is independently and spaced apart from the electrical chamber 1 on the electrical box body 2. The output end of the driver 4 is connected to the transmission component 19, and the transmission component 19 is connected to the push rod 3. The output force of the driver 4 is transmitted to the push rod 3 through the transmission component 19.

[0056] The driver 4 is located on the inside or outside of the mechanical transmission compartment 20.

[0057] In this embodiment, the driver 4 is a motor. The transmission assembly 19 is a gear transmission structure, and the push rod 3 is equipped with a rack.
