[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 1-7 A transmission box for an automatic push-pull door lock assembly for a dishwasher includes a box body 1. The box body 1 is provided with a driver 2, a push rod 3 and a transmission component 4. The box body 1 is provided with a transmission component mounting cavity 5 on the side corresponding to the push rod 3 for accommodating and installing the transmission component 4.

[0027] The driver 2 is located inside or outside the mounting cavity 5 of the transmission component. The output end of the driver 2 is connected to the input end of the transmission component 4. The output end of the transmission component 4 is connected to the push rod 3. The driver 2 drives the push rod 3 to perform axial extension and retraction on the box 1 through the transmission component 4.

[0028] The expansion of the dishwasher market is accompanied by the continuous emergence of new functions, and the push-rod ejection structure has gradually become a common feature in dishwasher design. However, existing technology still has certain limitations in the transmission structure design of the push-pull door lock assembly. These limitations are mainly reflected in the fact that the connection between the driver 2, push rod 3, and transmission component 4 is not tight enough, resulting in low transmission efficiency. Furthermore, in practical applications, the extension and retraction movement of push rod 3 is not stable enough, affecting the overall user experience.

[0029] In a home environment, the dishwasher's sliding door lock assembly needs to have a fast and stable opening and closing function. Traditional designs often cannot meet the needs of frequent use, leading to malfunctions or sluggish responses after prolonged use. Therefore, designing a new type of transmission box structure is particularly important to address this issue.

[0030] This application proposes a transmission box for an automatic push-pull door lock assembly of a dishwasher. By designing a compact box body 1, which houses a driver 2, a push rod 3, and a transmission component 4, the transmission efficiency can be effectively improved. The transmission connection between the driver 2 and the transmission component 4 is more rational, ensuring that the push rod 3 can achieve stable axial extension and retraction within the box body 1.

[0031] The technical features of this application include a housing 1, a driver 2, a push rod 3, a transmission assembly 4, and a transmission assembly mounting cavity 5. The housing 1 is used to mount other components, the driver 2 provides power, the push rod 3 performs the push-pull action, and the transmission assembly 4 transmits the power from the driver 2 to the push rod 3. The transmission assembly mounting cavity 5 is used to accommodate and fix the transmission assembly 4. These technical features, through their mutual cooperation, enable the driver 2 to drive the push rod 3 to axially extend and retract within the housing 1, thereby effectively solving the transmission structure design problem of the dishwasher's automatic push-pull door lock assembly.

[0032] Comparative analysis with existing technologies reveals that the transmission box design of this application is more compact in structure, significantly improves transmission efficiency, and enhances the motion stability of the push rod 3. Furthermore, the multi-stage structure design of the transmission assembly 4 effectively reduces the load on the driver 2 and extends its service life.

[0033] Multi-stage transmission can increase the output torque of driver 2 (motor) and reduce motor power, making it suitable for use with small motors.

[0034] The technical solution of this application solves the problem of transmission structure design in the automatic push-pull door lock assembly of a dishwasher by rationally arranging the housing 1, driver 2, push rod 3, and transmission assembly 4. The design of the housing 1 allows for tight integration of all components, and the driver 2 effectively drives the push rod 3 to perform axial extension and retraction through the transmission assembly 4. The design of the transmission assembly 4 considers the meshing of gears, ensuring smoothness and efficiency during transmission. The movement of the push rod 3 is constrained by the positioning block, ensuring its stability within the mounting cavity. Through this design, the dishwasher's push-pull door lock assembly can achieve more efficient and stable operation in actual use, meeting the market's ever-increasing demands for dishwasher functionality.

[0035] The box body 1 is provided with a push rod mounting cavity 6 corresponding to the push rod 3. One end of the transmission component mounting cavity 5 is connected to the push rod mounting cavity 6. The other end of the transmission component mounting cavity 5 extends laterally along one side of the push rod mounting cavity 6; or, the other end of the transmission component mounting cavity 5 extends vertically along one side of the push rod mounting cavity 6.

[0036] This design solves the layout problem of push rod mounting cavity 6 and transmission component mounting cavity 5 by optimizing the layout of transmission component 4 and push rod 3, thus ensuring effective transmission connection between transmission component 4 and push rod 3.

[0037] The transmission component mounting cavity 5 can be designed to extend laterally or vertically. When extending laterally, the transmission component mounting cavity 5 is arranged horizontally along one side of the push rod mounting cavity 6, enabling the transmission component to achieve a transmission connection within a shorter distance. When extending vertically, the transmission component mounting cavity 5 is arranged vertically along one side of the push rod mounting cavity 6 (the transmission component mounting cavity 5 and the push rod mounting cavity 6 are parallel). Regardless of whether it extends laterally or vertically, a reasonable structural design can ensure a stable and reliable transmission connection between the transmission component 4 and the push rod 3.

[0038] This design effectively solves the layout problem of the push rod mounting cavity 6 and the transmission component mounting cavity 5, ensuring an effective transmission connection between the transmission component and the push rod. Compared with the prior art, the design of this application can better optimize the layout of the transmission component and the push rod, improve transmission efficiency and stability, thereby enhancing the overall performance of the dishwasher automatic push-pull door lock assembly.

[0039] The transmission component mounting cavity 5 is fixedly mounted on the box body 1, and the box body 1 and the transmission component mounting cavity 5 are configured as a whole; or, the box body 1 and the transmission component mounting cavity 5 are configured separately, and the transmission component mounting cavity 5 is detachably mounted on the box body 1.

[0040] The housing 1 is constructed using injection molding, comprising a transmission component mounting cavity 5, a push rod mounting cavity 6, and a receiving cavity 7 for mounting the driver 2. The transmission component mounting cavity 5 can be mounted on the housing 1 via bolts, snap-fit ​​connections, or other detachable fixing methods (it can be understood that the transmission component mounting cavity 5 is located on another mounting box, which is detachably connected to the housing 1). This design facilitates the maintenance and replacement of the transmission component 4, increasing the service life and reliability of the dishwasher's automatic push-pull door lock assembly.

[0041] The transmission component 4 includes several meshing large and small gears, which are arranged vertically along the height of the push rod 3 to form a multi-stage transmission; the thickness of the transmission component 4 and the push rod 3 are similar; and / or the thickness of the transmission component 4 and the driver 2 are similar.

[0042] The overall height of the transmission component 4 is similar to that of the push rod 3, which helps to reduce the thickness of the door lock assembly, further optimizes the compactness of the overall device, significantly reduces space occupation, and improves the reliability and performance of the door lock assembly.

[0043] In actual implementation, the extension and retraction of push rod 3 is achieved by the power of driver 2. The output end of driver 2 is directly connected to the input end of transmission component 4. Transmission component 4 transmits power to push rod 3 through gear transmission or other means, ensuring that the action of push rod 3 is rapid and stable. The design of transmission component 4 can adopt a multi-stage gear structure to improve transmission efficiency, and a gear positioning rotating part 8 is set in the transmission component mounting cavity 5 to ensure stable operation of the gears.

[0044] The transmission component mounting cavity 5 is provided with a gear positioning rotating part 8 for positioning and mounting a plurality of gears. The gear positioning rotating part 8 extends upward from the bottom wall of the transmission component mounting cavity 5. The gear positioning rotating part 8 and the transmission component mounting cavity 5 are configured as a whole. Alternatively, the gear positioning rotating part 8 is detachably mounted on the transmission component mounting cavity 5. The driver 2 drives the transmission component 4 to run. Each gear positioning rotating part 8 forms the rotation fulcrum of the gear.

[0045] The transmission assembly mounting cavity 5 is equipped with a gear positioning rotating part 8 for positioning and mounting the gear, ensuring stable positioning of the gear during operation and facilitating gear installation. When the driver 2 drives the transmission assembly 4, the gear positioning rotating part 8 forms the rotation fulcrum of the gear, ensuring smooth rotation of the gear during transmission. In this way, the problems of unstable positioning and uneven rotation that may occur with the gears in the transmission assembly 4 during operation are solved.

[0046] The gear positioning rotating part can be implemented in various ways. For example, a bearing-type rotating component can be used to reduce friction and wear, ensuring smooth gear rotation. Stable gear positioning and smooth rotation can also be achieved by setting a fixed shaft or a sliding shaft. The material of the gear positioning rotating part 8 can be selected from wear-resistant and high-strength materials, such as steel or high-strength engineering plastics, to extend its service life and improve reliability. Furthermore, the position and size of the gear positioning rotating part 8 can be adjusted according to the specific design of the transmission component 4 to accommodate gears of different types and sizes.

[0047] The drive 2 is mounted on the inner or outer side of the transmission component mounting cavity 5, and the drive 2 is limited to the mounting cavity 7. The mounting cavity 7 has an opening 9 that connects to the transmission component mounting cavity 5, corresponding to the output end of the drive 2.

[0048] The accommodating cavity 7 provides a stable space for installing the driver 2, ensuring that the driver 2 is not easily dislodged during operation. At the same time, the opening 9 enables an effective connection between the driver 2 and the transmission assembly 4, ensuring smooth and stable transmission.

[0049] The accommodating cavity 7 is provided with a driver lead notch 14 that connects to the outside.

[0050] The driver lead notch 14 is designed to allow the driver 2's leads to smoothly exit from the housing 7, thus enabling electrical connection between the driver 2 and the outside world. The driver lead notch 14 can be implemented in various ways. For example, the shape of the notch can be designed as rectangular or circular to accommodate different lead specifications; the size of the notch can be adjusted according to the thickness of the lead to ensure smooth passage; a protective structure can be added around the notch to prevent damage or detachment of the lead. Furthermore, the position of the notch can be optimized according to the layout of the driver and transmission components to ensure that the lead is not disturbed during movement.

[0051] The transmission assembly mounting cavity 5 has a receiving cavity 7 and an anti-detachment component 13 on its outer side. The driver 2 is limited and installed between the receiving cavity 7 and the anti-detachment component 13, which forms an anti-detachment part to prevent the driver 2 from detaching outward from the receiving cavity 7. This ensures that the driver is securely installed in the receiving cavity and will not be detached due to external forces or other factors, thereby improving the reliability and safety of the dishwasher's automatic push-pull door lock assembly. The anti-detachment component 13 can be made of various materials and structures, such as plastic or metal, and can be fixed to the outer side of the receiving cavity 7 by snap-on, screw fixing, or other suitable fixing methods. The shape and size of the anti-detachment component 13 should match the receiving cavity 7 and the driver 2 to ensure that the driver 2 can be firmly fixed in the receiving cavity without falling off. Furthermore, the anti-detachment component 13 can also be designed to have a certain degree of elasticity to provide cushioning and adaptability during installation and disassembly.

[0052] The housing 1 has a push rod mounting cavity 6, on which an upper positioning block 11 and a lower positioning block 12 are provided, spaced vertically. The push rod 3 is mounted on the push rod mounting cavity 6 for left and right positioning, and is positioned horizontally between the upper and lower positioning blocks 11 and 12 for vertical positioning. One end of the push rod mounting cavity 6 has an opening, and the push rod 3 extends and retracts through the opening under the action of the driver 2. This ensures that the push rod 3 remains stable during extension and retraction, avoiding deviation or jamming, thereby achieving effective control of the push rod 3. The extension and retraction of the push rod 3 is performed through the opening, allowing the push rod 3 to move smoothly under the action of the driver 2, solving the positioning and restriction problem of the push rod 3 within the push rod mounting cavity 6, and improving the reliability and functionality of the dishwasher's automatic push-pull door lock.

[0053] The automatic push-pull door lock assembly of the dishwasher also includes a cover 15 that fits onto the box body 1. The cover 15 is detachably mounted on the box body 1. The push rod 3 and the transmission assembly 4 are positioned between the cover 15 and the box body 1.

[0054] The design of the cover 15 allows for easy removal of the cover 15 when maintenance or replacement of internal components is required, providing quick access to the internal structure of the housing 1. This design enables users to easily disassemble and maintain the transmission box, solving the cumbersome disassembly and maintenance issues of traditional dishwasher transmission boxes and improving ease of use and maintenance efficiency. The cover 15's snap-on installation on the housing 1 facilitates easy disassembly and maintenance of the transmission box during use, thus addressing the need for convenient disassembly and maintenance of the automatic push-pull door lock assembly's transmission box.

[0055] The cover 15 can be implemented using different snap-fit ​​designs, such as spring-loaded, rotary, or sliding snap-fit. These designs ensure that the cover 15 is securely fixed to the housing 1 while allowing for easy removal when needed. Furthermore, the cover can be made of durable and lightweight plastic or metal to suit different usage environments and maintenance requirements.

[0056] In this embodiment, as Figure 2 As shown, when the accommodating cavity 7 is placed inside the box body 1, the motor shaft of the motor passes downward through the accommodating cavity 7 and connects to a drive gear. The box body 1 is provided with a transmission gear that meshes with the drive gear. The rotating shaft of the transmission gear passes through and is inserted into the box body 1. One of the gears of the transmission assembly 4 is set on the rotating shaft of the transmission gear. When the motor shaft rotates, the drive gear drives the transmission gear to rotate, and at the same time drives the gear of the transmission assembly 4 to rotate.

[0057] In this embodiment, as Figure 3 As shown, all gears of the transmission assembly 4 are housed in the housing 1, and the motor shaft is inserted through the cavity 7. The motor shaft is equipped with a drive gear that meshes with the gears of the transmission assembly 4.
