Description

Technical Field

[0001] This invention relates to the field of microwave oven technology, and particularly to a drawer-type microwave oven. Background Technology

[0002] With the continuous development of smart home technology, built-in kitchen appliances are becoming increasingly popular. Among them, drawer-type microwave ovens, steam ovens, and disinfection cabinets are favored by more and more consumers due to their advantages such as easy opening, space saving, and ergonomic operating height. Based on different driving methods, the opening and closing operations of drawer-type kitchen appliances on the market are currently divided into three main types: manual, semi-automatic (such as push-to-open), and fully automatic (electrically driven). Among these, fully automatic door opening and closing technology, due to its convenient functions such as one-button opening and closing, voice control, and integration with smart home systems, is gradually becoming the mainstream configuration for mid-to-high-end products.

[0003] In existing fully automatic door opening and closing technologies, a single-sided motor drive structure is commonly used, such as the previously disclosed invention patent CN104566534B, a microwave oven. This solution uses a motor to drive a push rod located in the middle of the lower end to move back and forth. The two sides of the drawer door are assisted by driven slide rails that slide passively without being actively connected to the push rod. The push rod drives the drawer door to open and close. When the equipment is used for a long time, the slide rails wear, assembly tolerances accumulate, or the uneven mounting surface causes inconsistent movement resistance on both sides of the slide rails, which can easily lead to asynchronous movement. The degree of asynchrony will gradually increase with the frequency of use. Specifically, during the opening or closing process, the drawer assembly may become misaligned, stuck, or make abnormal noises. More seriously, when the asynchrony intensifies to a critical state, the driven side slide rail may jam, while the motor continues to output power. At this time, the motor is in a stalled state, and the current rises sharply. This can not only cause the door opening and closing action to completely fail, but may also cause the motor to overheat and burn out, damage the control circuit board, and other serious consequences, seriously affecting the product's service life and user experience, and even posing certain safety hazards.

[0004] In addition, in order to avoid interference from internal components with the push rod, the assembly position of the push rod needs to be adjusted. Therefore, under the same size, this can only be achieved by sacrificing the installation space of other components or the furnace cavity space, which undoubtedly affects the product's expandability or usable space. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a drawer-type microwave oven. This invention enables the drawer door to open simultaneously under the force of both sides, solving the problems of door tilting, jamming, or abnormal noise caused by uneven force on one side, fundamentally eliminating the motion imbalance caused by resistance differences, and optimizing the structure of the drawer door guide drive device, which is beneficial to improving the utilization rate of the internal space of the equipment.

[0006] To achieve the above objectives, the present invention provides a drawer-type microwave oven, comprising:

[0007] The microwave oven body and the outer casing, with a first slide rail assembly and a second slide rail assembly respectively provided on both sides of the microwave oven body;

[0008] The drawer door has its two sides connected to a first slide rail assembly and a second slide rail assembly, respectively, enabling it to be pushed open and closed;

[0009] A drawer door guide drive device disposed on the microwave oven body, used to drive the opening and closing of the drawer door, the drawer door guide drive device comprising:

[0010] A drive assembly includes a drive motor, a synchronous belt, and a synchronous pulley set. The synchronous pulley set is coaxially arranged along the X-axis direction. The synchronous belt is sleeved on the synchronous pulley set and linked with the drive motor, so that the drive motor drives the synchronous belt to rotate along the X-axis direction.

[0011] A linkage assembly, comprising a folding linkage, a first connector, and a second connector, wherein the folding linkage is arranged along a second direction and is locked and linked with the timing belt, wherein both ends of the folding linkage are respectively connected to the first connector and the second connector, wherein the other end of the first connector away from the folding linkage is connected to the first slide rail assembly, and the other end of the second connector away from the folding linkage is connected to the second slide rail assembly;

[0012] The first guide and limiting component is located on either side of the folding link and limits and guides the folding link.

[0013] A first sensor switch and a second sensor switch are used to trigger the drawer door when it is in the open state and the drawer door is in the closed state, respectively.

[0014] A control device is electrically connected to a first inductive switch, a second inductive switch, and a drive motor.

[0015] Furthermore, the folding connecting rod includes a connecting rod body, with both ends of the connecting rod body bent to form a first connecting portion and a second connecting portion perpendicular to the connecting rod body. The first connecting portion is connected to the first connecting member, and the second connecting portion is connected to the second connecting member. By vertically arranging the first and second connecting portions, sufficient space is created between the connecting rod body and the microwave oven body, thereby increasing the usable space inside the microwave oven body without increasing the overall thickness, while also preventing interference with the folding connecting rod.

[0016] Furthermore, a first clearance structure, which protrudes upwards or is recessed downwards, is provided on the main body of the connecting rod, extending along the length of the main body of the connecting rod. By providing the first clearance structure, installation interference from other structural components inside the microwave oven body can be effectively avoided, ensuring that the folding connecting rod operates smoothly and without jamming during reciprocating motion.

[0017] Furthermore, a first reinforcing part is provided at the connection between the connecting rod body and the first connecting part, and a second reinforcing part is provided at the connection between the connecting rod body and the second connecting part. The provision of the first and second reinforcing parts can improve the rigidity of the first and second connecting parts, effectively preventing deformation or breakage caused by stress concentration during long-term use, thereby significantly extending the service life of the device; at the same time, the first and second reinforcing parts are symmetrically distributed, ensuring that the folding connecting rod is subjected to balanced force and has a precise movement trajectory during extension and retraction, further improving the smoothness and quietness of the drawer door opening and closing action.

[0018] Furthermore, the first guide limiting assembly includes a first limiting guide seat, a first guide wheel, and a first guide connecting shaft. The first limiting guide seat is arranged parallel to the synchronous belt. A first guide groove is provided on the first limiting guide seat. The first guide wheel is sleeved on the first guide connecting shaft through a bearing to achieve free rotation. The first guide wheel is embedded in the first guide groove and can move linearly along the first guide groove. One end of the first guide connecting shaft is connected to a first connecting part, and the other end of the first guide connecting shaft is connected to a first connecting piece. Alternatively, one end of the first guide connecting shaft is connected to a second connecting part, and the other end of the first guide connecting shaft is connected to a second connecting piece. By setting the first guide connecting shaft to connect the first connecting part and the first connecting piece or the second connecting part or the second connecting piece respectively, precise constraint on the movement trajectory of the folding linkage can be achieved, avoiding swaying and shaking. At the same time, the rolling contact of the first guide wheel in the first guide groove greatly reduces frictional resistance. Combined with the synchronous belt drive, the opening and closing process of the drawer door is more gentle, quiet, and responsive. Furthermore, the structure of this guide wheel and guide groove can effectively improve the guiding accuracy and long-term operational stability, especially in high-frequency opening and closing scenarios, it can still maintain a reliable fit with zero gap and no wear; and it can reduce the overall production cost.

[0019] Furthermore, the first and second inductive switches are respectively located at both ends of the first guide groove. When the first guide connecting shaft moves to its limit position, the corresponding switch signal is triggered. The first and second inductive switches are contact switches, triggering electrical signals to be fed back to the controller to determine the opening and closing status of the drawer door in real time, ensuring that the action is in place and the positioning is accurate. By monitoring the limit position of the movement of the first guide connecting shaft, stable opening and closing of the drawer can be achieved without significantly increasing costs, reducing the precision requirements of the manufacturing process.

[0020] Furthermore, a first switch mounting position and a second switch mounting position are provided on the first limiting guide seat to fix the first inductive switch and the second inductive switch, respectively. The first switch mounting position and the second switch mounting position are respectively located on the first and last sides of the first guide groove to ensure that the contacts of the first inductive switch and the second inductive switch are aligned with the movement trajectory of the first guide connecting shaft. This modular installation structure not only facilitates assembly and subsequent maintenance, but also supports flexible adjustment of the switch position according to actual stroke requirements, improving production line adaptability; at the same time, the symmetrical layout at both ends effectively avoids the risk of false signal triggering and enhances system robustness.

[0021] Furthermore, both the first and second switch mounting positions are equipped with switch plug-in posts and fasteners. Both the first and second inductive switches have plug-in interfaces that match the switch plug-in posts. The first and second inductive switches are doubly secured to their respective mounting positions via both fasteners and plug-in interfaces. This double-fixing structure significantly improves the stability and repeatability of switch installation, preventing loosening or displacement due to vibration or long-term use. The combination of the plug-in posts and fasteners provides both rapid assembly and impact resistance, greatly shortening the production line debugging cycle.

[0022] Furthermore, it also includes a second guide limiting component. The first guide limiting component and the second guide limiting component are respectively disposed on both sides of the folding link, and simultaneously limit and guide both ends of the folding link.

[0023] Furthermore, the second guide limiting assembly includes a second limiting guide seat, a second guide wheel, and a second guide connecting shaft. The second limiting guide seat is arranged parallel to the first limiting guide seat. A second guide groove is provided on the second limiting guide seat. The second guide wheel is sleeved on the second guide connecting shaft through a bearing to achieve free rotation. The second guide wheel is embedded in the second guide groove and can move linearly along the second guide groove. One end of the first guide connecting shaft is connected to the first connecting part, and the other end of the first guide connecting shaft is connected to the first connecting piece. One end of the second guide connecting shaft is connected to the second connecting part, and the other end of the second guide connecting shaft is connected to the second connecting piece. Through the coordinated constraint of the dual limiting assemblies, the swaying and shaking of the drawer door under long-term operation are avoided. Moreover, the dual limiting assemblies enable both ends of the folding linkage to play a good guiding, positioning, and supporting role, so that the folding linkage is subjected to balanced force and has a stable movement trajectory during opening and closing.

[0024] Furthermore, the two ends of the first guide connecting shaft are respectively provided with a first guide connecting part and a second guide connecting part. The first guide connecting part has a flat rectangular structure and a first flat rectangular hole that matches the first guide connecting part. The second guide connecting part has a threaded structure and a first internal threaded hole that matches it. The two ends of the second guide connecting shaft are respectively provided with a third guide connecting part and a fourth guide connecting part. The third guide connecting part has a flat rectangular structure and a second flat rectangular hole that matches the second connecting part. The fourth guide connecting part has a threaded structure and a second internal threaded hole that matches it. This flat rectangular and threaded composite connection structure balances precise positioning and reliable locking, effectively preventing axial movement and circumferential slippage, thereby improving the transmission accuracy and response consistency, and maintaining zero-backlash transmission even under high-frequency opening and closing conditions.

[0025] Furthermore, the first slide rail assembly includes a first slide rail fixed to one side of the microwave oven body and a first sliding plate movably connected to the first slide rail, the first sliding plate being connected to one side of the drawer door. The second slide rail assembly includes a second slide rail fixed to the other side of the microwave oven body and a second sliding plate movably connected to the second slide rail, the second sliding plate being connected to the other side of the drawer door. The dual slide rails achieve synchronous sliding and rigid support on both sides of the drawer door.

[0026] Furthermore, the first connector has a first fixing hole at its end away from the folding linkage, and a matching second fixing hole on the first sliding plate. Fasteners are used to lock the first mounting part and the first sliding plate together. The second mounting part has a third fixing hole at its end away from the folding linkage, and a corresponding fourth fixing hole on the second sliding plate. Both are also secured with fasteners. This fastening structure ensures a rigid and reliable force transmission path between the folding linkage and the slide rail assembly, preventing door misalignment and abnormal noise caused by loose connections.

[0027] Furthermore, the end of the first connector away from the folding linkage is folded back to form a first mounting portion, and the first fixing hole is disposed on the first mounting portion. The end of the first sliding plate extends and bends to form a second mounting surface that fits against the first mounting portion, and the second fixing hole is disposed on the second mounting surface. The end of the second connector away from the folding linkage is folded back to form a second mounting portion, and the third fixing hole is disposed on the second mounting portion. The end of the second sliding plate extends and bends to form a third mounting surface that fits against the second mounting portion, and the fourth fixing hole is disposed on the third mounting surface. This folded-back fitting structure significantly increases the contact area and bending stiffness, making the mounting portion less prone to deformation under repeated push-pull loads, ensuring that the linkage axis and the slide rail movement direction remain parallel for a long time, thereby maintaining the straightness and repeatability of the door opening and closing trajectory.

[0028] Furthermore, the first mounting portion extends outward to form a first wrapping portion, and a bent first locking portion is provided on the first wrapping portion, so that the first mounting portion, the first wrapping portion, and the first locking portion together form a U-shaped structure. A first locking hole is provided on the first sliding plate, and the first wrapping portion is in close contact with the first sliding plate, so that the first locking portion is inserted into the first locking hole. The second mounting portion extends outward to form a second wrapping portion, and a bent second locking portion is provided on the second wrapping portion, so that the second mounting portion, the second wrapping portion, and the second locking portion together form a U-shaped structure. A second locking hole is provided on the second sliding plate, and the second wrapping portion is in close contact with the second sliding plate, so that the second locking portion is inserted into the second locking hole. This U-shaped locking structure provides secondary mechanical limiting on the basis of fastener pre-tightening, effectively suppressing axial movement and rotational micro-sway of the mounting portion, and significantly reducing the impact vibration at the moment of door opening and stopping.

[0029] Furthermore, the synchronous pulley set includes a driving pulley and a driven pulley, both of which are toothed pulleys. The synchronous belt meshes with two of the toothed pulleys respectively. The driving pulley is driven to rotate by a motor, which in turn drives the synchronous belt to precisely pull the driven pulley to rotate synchronously.

[0030] Furthermore, it also includes a connecting rod fixing member, which is fixed to the inner circumferential surface of the timing belt. The connecting rod fixing member is connected to the folding connecting rod, so that the timing belt is clamped between the connecting rod fixing member and the folding connecting rod. Through the rigid engagement of the connecting rod fixing member and the folding connecting rod, zero-backlash power transmission is achieved; at the same time, the timing belt is clamped between the two, realizing the synchronous linkage between the folding connecting rod and the timing belt.

[0031] Furthermore, the connecting rod fixing component is provided with a connecting through hole, which matches the teeth of the timing belt, allowing the teeth of the timing belt to embed into the connecting through hole. Embedding the teeth of the timing belt into the connecting through hole can better achieve the linkage performance between the timing belt and the folding connecting rod, thereby maintaining motion synchronization accuracy under high-frequency start-stop conditions and effectively suppressing the slippage of the toothed belt.

[0032] Furthermore, the connecting rod fixing member is provided with a plurality of protrusions, which are embedded in the gaps between the teeth of the timing belt.

[0033] Furthermore, it also includes a speed-changing assembly, which comprises a motor main shaft pulley, a speed-changing pulley, and a speed-changing transmission belt. The motor main shaft pulley is linked to the drive motor, and the speed-changing transmission belt is fitted onto the motor main shaft pulley and the speed-changing pulley to achieve their linkage. The speed-changing pulley is coaxially linked with the drive pulley. By controlling the transmission ratio of the speed-changing pulley, the output torque and speed can be adjusted, thereby increasing the smoothness and stability of the drawer door opening and closing transmission.

[0034] Compared with the prior art, the present invention has the following advantages: The present invention can avoid excessive occupation of the internal space of the microwave oven body through the structural optimization of the folding linkage, thereby improving the utilization rate of the internal space of the microwave oven body. At the same time, the first and second connecting parts of the double U-shaped locking structure set at both ends of the folding linkage form a rigid fit and fixation with the sliding seat, which significantly improves the contact rigidity with the drawer door, effectively suppresses the connection loosening caused by high-frequency vibration, and realizes synchronous opening and closing and precise positioning of the drawer door. Through the above structure, the first and second slide rail groups connected on both sides of the drawer door can be subjected to force synchronously, completely eliminating the problems of door tilting, jamming or abnormal noise caused by uneven force on one side.

[0035] The first and second guide limiting components support the linkage assembly, enhancing its stability, and guide it to prevent it from swaying and thus the drawer door from shaking.

[0036] The first and second guide limiting components located on both sides employ guide wheels and guide grooves, which significantly reduces production costs structurally. Functionally, they precisely constrain the lateral displacement and pitch swing of the drawer door during opening and closing, improving the coaxiality and trajectory stability of the folding linkage at both ends, thus ensuring that the drawer door maintains millimeter-level positioning accuracy throughout its entire stroke. In particular, in addition to the aforementioned guiding and positioning functions, this structure also provides support to both ends of the folding linkage, preventing bending deformation of the linkage due to the cantilever effect after prolonged use, and greatly extending the service life of the linkage assembly.

[0037] The transmission assembly works in conjunction with the synchronous pulley set to provide high torque output to overcome friction during low-speed start-stop phases, and to reduce inertial impact during high-speed operation, so that the door movement remains smooth and quiet throughout.

[0053] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. All other embodiments of the present invention obtained by those skilled in the art based on this embodiment without creative effort are within the scope of protection of the present invention.

[0054] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] Furthermore, if the embodiments of the present invention involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0056] like Figures 1 to 2 As shown, an embodiment of the present invention provides a drawer-type microwave oven, which includes a microwave oven body 1, a shell 11, a drawer door 2, and a drawer door guide drive device 3. The drawer door guide drive device 3, disposed on the microwave oven body 1, is used to drive the opening and closing of the drawer door 2, achieving synchronous and smooth extension and retraction of both sides of the drawer door 2. Figure 3 and Figure 4 As shown, the drawer door guide drive device 3 includes: a drive assembly 4, a connecting rod assembly 5, a first guide limit assembly 6, a first inductive switch 81, a second inductive switch 82, and a control device 8.

[0057] The following is combined Figures 1 to 11 The above-mentioned drawer-type microwave oven will be further explained.

[0058] like Figure 1 and Figure 2 As shown, the outer shell 11 is assembled from a front panel 111, two side panels 112, a bottom panel 113, a top panel 115, and a rear panel 114. The outer shell 11 covers the microwave oven body 1 to protect the microwave oven body 1. An oven cavity 12 is formed inside the microwave oven body 1. In addition to the oven cavity 12, the microwave oven body 1 is also equipped with other conventional components, such as a microwave generator, a magnetron, a high-voltage transformer, and a cooling fan.

[0059] like Figures 3 to 5As shown, a first slide rail assembly 13 and a second slide rail assembly 14 are respectively provided on both sides of the microwave oven body 1. The two sides of the drawer door 2 are respectively connected to the first slide rail assembly 13 and the second slide rail assembly 14 to realize pushable opening and closing. In this embodiment, the drawer door 2 includes a door body 21 and a drawer 22 for storing food. When the drawer 22 is in operation, it can be inserted into the oven cavity 12. The door body 21 is used to seal the opening of the oven cavity 12.

[0060] The first slide rail assembly 13 and the second slide rail assembly 14 are preferably disposed between the outer wall of the oven cavity 12 and the two side panels 112. In this embodiment, the first slide rail assembly 13 includes a first slide rail 131 fixed to one side of the microwave oven body 1 and a first sliding plate 132 movably connected to the first slide rail 131. The first sliding plate 132 is connected to one side of the drawer door 2. The second slide rail assembly 14 includes a second slide rail 141 fixed to the other side of the microwave oven body 1 and a second sliding plate 142 movably connected to the second slide rail 141. The second sliding plate 142 is connected to the other side of the drawer door 2. Thus, the drawer door 2 can slide smoothly along the first slide rail 131 and the second slide rail 141, achieving synchronous extension and retraction from left to right.

[0061] Combination Figure 6 As shown, the aforementioned drive assembly 4 includes a drive motor 41, a synchronous belt 42, and a synchronous pulley set 43. The synchronous pulley set 43 is coaxially arranged along the X-axis direction. The synchronous belt 42 is sleeved on the synchronous pulley set 43 and linked with the drive motor 41, so that the drive motor 41 drives the synchronous belt 42 to rotate along the X-axis direction. In this embodiment, the synchronous pulley set 43 includes a driving pulley 431 and a driven pulley 432. Both the driving pulley 431 and the driven pulley 432 are toothed pulleys. The synchronous belt 42 meshes with the two toothed pulleys respectively. The driving pulley 431 is driven to rotate by the drive motor 41, which drives the synchronous belt 42 to precisely pull the driven pulley 432 to rotate synchronously.

[0062] Furthermore, it also includes a speed change assembly 44, which includes a motor main shaft pulley 441, a speed change pulley 442, and a speed change transmission belt 443. The motor main shaft pulley 441 is linked with the drive motor 41. The speed change transmission belt 443 is sleeved on the motor main shaft pulley 441 and the speed change pulley 442 to achieve linkage between the two. The speed change pulley 442 is coaxially linked with the drive pulley 431. In this embodiment, the size of the speed change pulley 442 is larger than that of the motor main shaft pulley 441. By controlling the transmission ratio of the speed change pulley 442, the output torque and speed can be adjusted, thereby increasing the smoothness and stability of the opening and closing transmission of the drawer door 2.

[0063] like Figure 5 and Figure 6As shown, the linkage assembly 5 includes a folding linkage 51, a first connector 52, and a second connector 53. The folding linkage 51 is arranged along the Y-axis direction. The folding linkage 51 is locked and linked with the timing belt 42. The two ends of the folding linkage 51 are respectively connected to the first connector 52 and the second connector 53. The other end of the first connector 52 away from the folding linkage 51 is connected to the first slide rail assembly 13. The other end of the second connector 53 away from the folding linkage 51 is connected to the second slide rail assembly 14.

[0064] Specifically, such as Figure 2 As shown, the X-axis direction is along the length of the microwave oven body 1, and the Y-axis direction is along the width of the microwave oven body 1.

[0065] like Figure 7 As shown, the folding connecting rod 51 in this embodiment includes a connecting rod body 511. The two ends of the connecting rod body 511 are bent to form a first connecting portion 512 and a second connecting portion 513, which are perpendicular to the connecting rod body 511. The first connecting portion 512 is connected to a first connecting member 52, and the second connecting portion 513 is connected to a second connecting member 53. By vertically arranging the first connecting portion 512 and the second connecting portion 513, the connecting rod body 511 protrudes outward, forming sufficient space between itself and the microwave oven body 1. This increases the usable space inside the microwave oven body 1 without increasing the overall thickness, while also preventing interference with the folding connecting rod 51.

[0066] Preferably, a first clearance structure 5111, which protrudes upward or is recessed downward, is provided on the connecting rod body 511. The first clearance structure 5111 extends along the length of the connecting rod body 511. The first clearance structure 5111 can effectively avoid installation interference from other structural components inside the microwave oven body 1, ensuring that the folding connecting rod 51 runs smoothly and without jamming during reciprocating motion; for example Figure 6 As shown, an outwardly protruding structure 15 is formed in the middle of the microwave oven body 1. At this time, the first clearance structure 5111 can avoid the outwardly protruding structure 15 and operate smoothly without having to consider modifying the structure of the microwave oven body 1 to avoid interference with the folding connecting rod 51.

[0067] In some implementations, multiple first air-proof structures 5111 can be provided, with the specific number selected according to the internal structure of the microwave oven body 1.

[0068] Furthermore, a first reinforcing part 514 is provided at the connection between the connecting rod body 511 and the first connecting part 512, and a second reinforcing part 515 is provided at the connection between the connecting rod body 511 and the second connecting part 513. The provision of the first reinforcing part 514 and the second reinforcing part 515 can improve the rigidity of the first connecting part 512 and the second connecting part 513, effectively preventing deformation or breakage caused by stress concentration during long-term use, thereby significantly extending the service life of the device. At the same time, the first reinforcing part 514 and the second reinforcing part 515 are symmetrically distributed, ensuring that the folding connecting rod 51 is subjected to balanced force and has a precise movement trajectory during the extension and retraction process, further improving the smoothness and quietness of the opening and closing action of the drawer door 2.

[0069] Furthermore, the folding link 51 in this embodiment is designed as a flat plate structure, which can further reduce the space requirement and has better structural rigidity. Of course, a cylindrical link structure can also be used as a replacement, but the cylindrical link structure takes up more space.

[0070] To achieve the locking linkage between the aforementioned folding linkage 51 and the timing belt 42, as follows: Figure 7 As shown, this embodiment also includes a connecting rod fixing member 54, which is fixed to the inner circumferential surface of the synchronous belt 42. The connecting rod fixing member 54 is connected to the folding connecting rod 51, so that the synchronous belt 42 is clamped between the connecting rod fixing member 54 and the folding connecting rod 51. For example, corresponding mounting holes are provided on the connecting rod fixing member 54 and the folding connecting rod 51, and locked by screws and nuts. The connecting rod fixing member 54 and the folding connecting rod 51 are rigidly fitted together to achieve zero-backlash power transmission; at the same time, the synchronous belt 42 is clamped between the two to achieve synchronous linkage between the folding connecting rod 51 and the synchronous belt 42.

[0071] Furthermore, the connecting rod fixing member 54 is provided with a connecting through hole 541, which matches the teeth 421 of the timing belt 42, so that the teeth 421 of the timing belt 42 are embedded in the connecting through hole 541. Multiple connecting through holes 541 can be provided, and their positions are adapted to the teeth 421. Embedding the teeth 421 of the timing belt 42 into the connecting through hole 541 can better realize the linkage performance between the timing belt 42 and the folding connecting rod 51, so as to maintain the motion synchronization accuracy under high frequency start and stop conditions and effectively suppress the slippage of the toothed belt.

[0072] In other embodiments, the connecting rod fixing member 54 is provided with a plurality of protrusions (not shown in the figure). The protrusions are embedded in the gaps between the teeth 421 of the timing belt 42. By replacing the connecting through hole 541 mentioned above with the protrusions, the locking function can also be achieved, thereby improving the firmness between the timing belt 42 and the folding connecting rod 51.

[0073] Combination Figure 4 and Figure 6As shown, the first guide limiting component 6 can be disposed on either side of the folding link 51, and limits, guides and supports the folding link 51; in this embodiment, a second guide limiting component 7 is preferably also provided, that is, the first guide limiting component 6 and the second guide limiting component 7 are provided simultaneously. The first guide limiting component 6 and the second guide limiting component 7 are respectively disposed on both sides of the folding link 51, and simultaneously limit and guide both ends of the folding link 51. That is, the second guide limiting component 7 is disposed on the other side relative to the first guide limiting component 6. It should be noted that the first guide limiting component 6 and the second guide limiting component 7 have the same structure and are symmetrically arranged.

[0074] like Figure 8As shown, the first guide limiting assembly 6 in this embodiment includes a first limiting guide seat 61, a first guide wheel 62, and a first guide connecting shaft 63. The first limiting guide seat 61 is arranged parallel to the synchronous belt 42. A first guide groove 611 is provided on the first limiting guide seat 61. The first guide wheel 62 is sleeved on the first guide connecting shaft 63 through a bearing to achieve free rotation. The first guide wheel 62 is embedded in the first guide groove 611 and can move linearly along the first guide groove 611. The second guide limiting assembly 7 includes a second limiting guide seat 71, a second guide wheel 72, and a second guide connecting shaft 73. The second limiting guide seat... 71 is arranged parallel to the first limiting guide seat 61. A second guide groove 711 is provided on the second limiting guide seat 71. The second guide wheel 72 is sleeved on the second guide connecting shaft 73 through a bearing to achieve free rotation. The second guide wheel 72 is embedded in the second guide groove 711 and can move linearly along the second guide groove 711. One end of the first guide connecting shaft 63 is connected to the first connecting part 512, and the other end of the first guide connecting shaft 63 is connected to the first connecting member 52. One end of the second guide connecting shaft 73 is connected to the second connecting part 513, and the other end of the second guide connecting shaft 73 is connected to the second connecting member 53. By setting a first guide connecting shaft 63 to connect the first connecting part 512 and the first connecting piece 52 respectively, and a second guide connecting shaft 73 to connect the second connecting part 513 and the second connecting piece 53 respectively, precise constraint on the movement trajectory of the folding linkage 51 can be achieved, avoiding swaying and shaking. At the same time, the rolling contact of the first guide wheel 62 and the second guide wheel 72 in the first guide groove 611 and the second guide groove 711 respectively greatly reduces frictional resistance. With the synchronous belt 42 driving, the opening and closing process of the drawer door 2 is more gentle, quiet and responsive. Moreover, this structure of guide wheel and guide groove can effectively improve guiding accuracy and long-term operational stability, especially in high-frequency opening and closing scenarios, it can still maintain a reliable fit with zero gap and no wear; and it can also reduce the overall production cost. Furthermore, it can achieve coordinated constraint on both ends of the folding linkage 51, thereby preventing the drawer door 2 from swaying and shaking during long-term operation. Moreover, the dual limiting components ensure that both ends of the folding linkage 51 provide good guidance, positioning, and support, ensuring balanced force and stable movement trajectory during opening and closing. The two sets of guide and limiting components support the linkage assembly 5, enhancing its stability, and guide it to prevent swaying and shaking of the drawer door 2.

[0075] Preferably, a first wrapping edge 612 and a second wrapping edge 712 are respectively provided on the outer side of the first guide groove 611 and the second guide groove 711 to limit the first guide wheel 62 and the second guide wheel 72, so as to prevent them from derailing and affecting the overall running accuracy.

[0076] In some embodiments, only the first guide limiting component 6 or the second guide limiting component 7 may be provided. For example, a single first guide limiting component 6 may be provided, which can be positioned on either side of the folding link 51 as needed. For instance, when positioned on the left side of the folding link 51, one end of the first guide connecting shaft 63 is connected to the first connecting portion 512, and the other end of the first guide connecting shaft 63 is connected to the first connecting member 52. Alternatively, when positioned on the right side of the folding link 51, one end of the first guide connecting shaft 63 is connected to the second connecting portion 513, and the other end of the first guide connecting shaft 63 is connected to the second connecting member 53. Similarly, the same applies to providing only a single second guide limiting component 7. It should be noted that providing only one guide limiting component results in slightly lower synchronization compared to the preferred scheme of providing both sides simultaneously, but it still serves the same positioning and guiding function.

[0077] The first sensor switch 81 and the second sensor switch 82 are used to trigger the stop when the drawer door 2 is in the open state and the closed state, respectively. Figure 8 As shown, the first inductive switch 81 and the second inductive switch 82 are respectively located at both ends of the first guide groove 611. When the first guide connecting shaft 63 moves to its extreme positions at both ends, the corresponding switch is triggered, thereby controlling the drive motor 41 to stop. The first inductive switch 81 and the second inductive switch 82 are respectively located at both ends of the first guide groove 611. These first inductive switches 81 and the second inductive switch 82 are contact switches or micro switches, which feed back the trigger electrical signal to the controller to determine the extreme positions of the drawer door 2 in the open and closed state in real time, ensuring that the action is in place, the positioning is accurate, and the machine stops in time. By monitoring the extreme positions of the movement of the first guide connecting shaft 63, stable opening and closing of the drawer can be achieved without significantly increasing costs, reducing the precision requirements of the manufacturing process. At the same time, because the signal contact position is changed to the first guide groove 611, the three micro switches on the original microwave oven can be eliminated, so that the inductive switches in this embodiment can operate independently from other micro switches, and the two signals do not interfere with each other, improving the accuracy of drawer door control.

[0078] Preferably, in this embodiment, a third sensor switch 83 and a fourth sensor switch 84 are also provided, with functions corresponding to the first sensor switch 81 and the second sensor switch 82. Correspondingly, the third sensor switch 83 and the fourth sensor switch 84 are located on both ends of the second guide groove 711. The third sensor switch 83 has the same function as the first sensor switch 81, which is used to trigger when the drawer door 2 is in the open state; the fourth sensor switch 84 has the same function as the second sensor switch 82, which is used to trigger when the drawer door 2 is in the closed state. Through this symmetrically arranged switch combination, the synchronous operation state of the folding linkage 51 can be effectively detected. If asynchronous triggering occurs, such as the first sensor switch 81 being triggered while the third sensor switch 83 is not triggered, the control device 8 can detect and report an error, and perform timely maintenance to avoid damage to components such as the drive motor 41 caused by forced operation.

[0079] As a preferred option, such as Figure 8 and Figure 9 As shown, a first switch mounting position 613 and a second switch mounting position 614 are provided on the first limiting guide seat 61 to fix the first inductive switch 81 and the second inductive switch 82, respectively. The first switch mounting position 613 and the second switch mounting position 614 are respectively located on the first guide groove 611 at both ends to ensure that the contacts of the first inductive switch 81 and the second inductive switch 82 are aligned with the movement trajectory of the first guide connecting shaft 63. Preferably, the contacts of the first inductive switch 81 and the second inductive switch 82 are placed inside the first guide groove 611. Similarly, a third switch mounting position 713 and a fourth switch mounting position 714 are provided on the second limiting guide seat 71 to fix the third inductive switch 83 and the fourth inductive switch 84, respectively. The third switch mounting position 713 and the fourth switch mounting position 714 are respectively located on the first and last ends of the second guide groove 711 to ensure that the contacts of the third inductive switch 83 and the fourth inductive switch 84 are aligned with the movement trajectory of the second guide groove 711. Preferably, the contacts of the third inductive switch 83 and the fourth inductive switch 84 are placed inside the second guide groove 711. This modular installation structure not only facilitates assembly and subsequent maintenance, but also allows for flexible adjustment of switch positions according to actual travel requirements, improving production line adaptability; at the same time, the symmetrical layout at both ends effectively avoids the risk of signal mis-triggeredness and enhances system robustness.

[0080] Furthermore, such as Figure 8As shown, both the first switch mounting position 613 and the second switch mounting position 614 are provided with a first switch insertion post 615 and a first fastening member 616. Both the first sensor switch 81 and the second sensor switch 82 are provided with a first insertion interface 85 that matches the first switch insertion post 615. The first sensor switch 81 and the second sensor switch 82 are doubly fixed to their respective first switch mounting positions 613 and 614 by their corresponding first fastening members 616 and first insertion interfaces 85. For example, the first insertion interface 85 on the first sensor switch 81 is inserted into the first switch insertion post 615 on the first switch mounting position 613, and then the first fastening member 616 on the first switch mounting position 613 will lock the end face of the first sensor switch 81 to achieve double fixation. Other positions are set up similarly. The third switch mounting position 713 and the fourth switch mounting position 714 have the same structure as the first switch mounting positions 613 and 614. Figure 9 As shown, a second switch insertion post 715 and a second fastening member 716 are provided on both the third switch mounting position 713 and the fourth switch mounting position 714. Both the third sensor switch 83 and the fourth sensor switch 84 are provided with a second insertion interface 86 that matches the second switch insertion post 715. The third sensor switch 83 and the fourth sensor switch 84 are doubly fixed to their respective third switch mounting positions 713 and fourth switch mounting positions 714 by their respective second fastening members 716 and second insertion interfaces 86. This double-fixing structure significantly improves the stability and repeatability of switch installation, avoiding loosening or displacement due to vibration or long-term use. The combination of the insertion post and the fastening member provides both rapid assembly and impact resistance, greatly shortening the production line debugging cycle.

[0081] Combination Figure 8 and Figure 9As shown, the two ends of the first guide connecting shaft 63 are respectively provided with a first guide connecting part 631 and a second guide connecting part 632. The first guide connecting part 631 has a flat rectangular structure, and a first flat rectangular hole 5121 matching the first guide connecting part 631 is provided on the first connecting part 512. The first guide connecting part 631 is inserted into the first flat rectangular hole 5121. The second guide connecting part 632 has a threaded structure, and a first internal threaded hole 521 matching the first connecting member 52 is provided on it. After the second guide connecting part 632 passes through the first internal threaded hole 521, it is locked by a locking member. The two ends of the second guide connecting shaft 73 are respectively provided with a third guide connecting part 731 and a fourth guide connecting part 732. The third guide connecting part 731 has a flat rectangular structure, and a first internal threaded hole 521 matching the first connecting part 512 is provided on the second connecting part 512. The third guide connection 731 is inserted into the second flat square hole 5131, which matches the third guide connection 731. The fourth guide connection 732 is a threaded structure. The second connector 53 is provided with a matching second internal thread hole 531. After the fourth guide connection 732 passes through the second internal thread hole 531, it is locked by a locking member. The locking member is a locking nut. It adopts a flat square and threaded composite connection structure, which takes into account both accurate positioning and reliable locking, and effectively prevents axial movement and circumferential slippage. This realizes the linkage of the folding connecting rod 51, the first guide limit assembly 6 / the second guide limit assembly 7 and the first connector 52 / the second connector 53, thereby improving the transmission accuracy and response consistency, especially maintaining zero-backlash transmission under high-frequency opening and closing conditions.

[0082] like Figure 10 and Figure 11 As shown, the first connector 52 has a first fixing hole 522 at the other end away from the folding link 51, and the first sliding plate 132 has a matching second fixing hole 1321. The first mounting part 523 and the first sliding plate 132 are locked together by fasteners. The second connector 53 has a third fixing hole 532 at the other end away from the folding link 51, and the second sliding plate 142 has a fourth fixing hole 1421 at the corresponding position. The two are also locked together by fasteners such as screws / bolts. This fastening structure ensures that the force transmission path between the folding link 51 and the slide rail assembly is rigid and reliable, and prevents the door body 21 from being unbalanced and making abnormal noises due to loose connections.

[0083] Furthermore, the end of the first connecting member 52 away from the folding connecting rod 51 is folded back to form a first mounting portion 523. A first fixing hole 522 is provided on the first mounting portion 523. The end of the first sliding plate 132 extends and bends to form a second mounting surface 1322 that fits against the first mounting portion 523. A second fixing hole 1321 is provided on the second mounting surface 1322. The end of the second connecting member 53 away from the folding connecting rod 51 is folded back to form a second mounting portion 533. A third fixing hole 532 is provided on the second mounting portion 533. The end of the second sliding plate 142 extends and bends to form a third mounting surface 1422 that fits against the second mounting portion 533. A fourth fixing hole 1421 is provided on the third mounting surface 1422. This folded-back fitting structure significantly increases the contact area and bending stiffness, making the mounting portion less prone to deformation under repeated push and pull loads. It ensures that the connecting rod axis and the slide rail movement direction remain parallel for a long time, thereby maintaining the straightness and repeatability of the door body 21 opening and closing trajectory.

[0084] Preferably, the first mounting portion 523 extends outward to form a first wrapping portion 524, and a bent first fastening portion 525 is provided on the first wrapping portion 524, so that the first mounting portion 523, the first wrapping portion 524 and the first fastening portion 525 together form a U-shaped structure. A first fastening hole 1323 is provided on the first sliding plate 132, and the first wrapping portion 524 is in close contact with the first sliding plate 132, so that the first fastening portion 525 is inserted into the first fastening hole 1323. The second mounting portion 533 extends outward to form a second wrapping portion 534, and a bent second fastening portion 535 is provided on the second wrapping portion 534, so that the second mounting portion 533, the second wrapping portion 534 and the second fastening portion 535 together form a U-shaped structure. A second fastening hole 1423 is provided on the second sliding plate 142, and the second wrapping portion 534 is in close contact with the second sliding plate 142, so that the second fastening portion 535 is inserted into the second fastening hole 1423. The U-shaped locking structure provides secondary mechanical limiting on the basis of pre-tightening of fasteners, effectively suppressing axial movement and micro-rotation of the installation part, and significantly reducing the impact vibration of the door 21 at the moment of opening and stopping.

[0085] The control device 8 is electrically connected to the first induction switch 81, the second induction switch 82 and the drive motor 41 respectively. The control device 8 is integrated on the microwave oven body and synchronously controls the operation of other components of the microwave oven body.

[0086] In some implementations, such as Figure 12As shown, the first connector 52 and the second connector 53 can be directly connected to the lower ends of both sides of the door body 21. For example, if a front through hole 116 is opened at the lower end of the front panel 111, the first connector 52 and the second connector 53 are arranged in the X-axis direction and pass through the front through hole to be fixed to the door body 21. In this case, the first connector 52 and the second connector 53 do not need to be connected to the first sliding plate 132 and the second sliding plate 142. Thus, the first connector 52 and the second connector 53 are arranged parallel to the first slide rail assembly 13 and the second slide rail assembly 14, and the drawer door 2 is simultaneously subjected to force on both sides for a guiding effect, which is consistent with the above-mentioned preferred solution.

[0087] Brief description of the working principle of the present invention: When the drawer door 2 needs to be opened, the controller integrated in the front panel controls the drive motor 41 to start, which sequentially drives the motor main shaft pulley 441, the speed-changing pulley 442, and the drive wheel 431 to rotate. The drive wheel 431 drives the synchronous belt 42 to rotate synchronously. The synchronous belt 42 drives the folding linkage 51 to move. The folding linkage 51 drives the first sliding plate 132 and the second sliding plate 142 to move forward through the first connecting piece 52 and the second connecting piece 53 connected at both ends, thereby realizing the opening of the drawer door 2. At the same time as the folding linkage 51 moves, the first guide wheel 62 and the second guide wheel 72 will roll forward synchronously with the folding linkage 51 along the first guide groove 611 and the second guide groove 711, thereby opening the drawer door 2. The two ends of the linkage 51 serve to position, guide, and support. When the first guide wheel 62 and the second guide wheel 72 move to their extreme positions, the first guide connecting shaft 63 and the second guide connecting shaft 73 will simultaneously touch the second induction switch 82 and the fourth induction switch 84. At this time, the controller receives the trigger signal and controls the drive motor 41 to stop, thereby stopping the displacement of the drawer door 2 and putting it in the open state. Similarly, when it is necessary to close the drawer door 2, the controller is activated to make the drive motor 41 move in the reverse direction. It should be noted that when the drawer door 2 is reset to its extreme position, the first guide connecting shaft 63 and the second guide connecting shaft 73 will simultaneously touch the first induction switch 81 and the third induction switch 83, and the drive motor 41 will stop, putting the drawer door 2 in the closed state.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
