[0002] A microwave oven is a common kitchen appliance that uses microwaves to heat food.

[0003] Traditional microwave ovens consist of an oven cavity and a rotating door located on the front. The oven cavity is relatively deep and has a turntable inside, which is usually used to load and unload plates horizontally, making it inconvenient for loading and unloading large plates. At the same time, the oven door requires sufficient space in front of the microwave oven to open. When it is located under a cabinet or countertop (especially when it is less than 50cm from the ground), users need to squat or bend over to operate it, which is not suitable for small kitchens or modern minimalist kitchen designs.

[0004] As a result, drawer-type microwave ovens have appeared on the market. These include an oven cabinet and a drawer that slides out of the cabinet. When the drawer is opened, users can directly take out the plates vertically. They can be installed under cabinets or countertops with low height, which is convenient for taking out and putting in large plates, and it is also easier to take them out.

The drive wheel 511 is first mounted on the drive wheel auxiliary mounting bracket 515, and then the drive wheel auxiliary mounting bracket 515 is aligned with the drive wheel mounting slot 5141 and mounted on the wheel mounting seat 514. Finally, the two are fixedly connected by screws to realize the detachable connection between the drive wheel auxiliary mounting bracket 515 and the wheel mounting seat 514.

[0059] Driven wheel 512 has a driven wheel body and a driven shaft. Driven wheel mounting slot 5142 has a guide groove that matches the diameter of the driven shaft and a shaft mounting slot with a diameter larger than that of the driven shaft. The guide groove and the shaft mounting slot are interconnected. When the driven shaft enters the shaft mounting slot through the guide groove, a fixing nut is threaded onto both ends of the driven shaft. In this embodiment, the fixing nut is a stepped nut 517, which has a stepped portion that can be inserted into the shaft mounting slot to prevent the driven shaft from disengaging from the driven wheel mounting slot 5142 and to achieve quick installation.

[0060] In another embodiment, one end of one of the driven shafts may be integrally formed with a stepped portion, and the other end of the shaft may be fixedly connected by a stepped nut 51.

[0061] In another embodiment, the driven wheel mounting slot 5142 is a circular driven shaft mounting hole, a bearing is provided in the driven shaft mounting hole, the driven shaft of the driven wheel 512 is located between two bearings, and the outer end of the driven wheel 512 is limited by a fixing nut or a snap ring.

[0062] Motor 52 drives the drive wheel 511 to rotate. To reduce the installation width, motor 52 is located above or below the synchronous belt assembly 51. In this embodiment, the motor is located below the synchronous belt assembly 51 and is fixed to one side of the wheel mounting base 514 by a motor fixing plate 524, forming a stable support structure with the synchronous belt assembly 51. An output wheel 521 is mounted on the main shaft of motor 52, and a synchronously rotating input wheel 522 is provided on one side of the drive wheel 511. The output wheel 521 and the input wheel 522 are connected by an output belt 523, which is preferably a synchronous belt. In this embodiment, a synchronous belt is used for rotation, which has advantages such as low noise, low vibration, and high transmission accuracy, and can improve the movement accuracy and stability of drawer 4 and reduce the noise of drawer opening and closing device 5.

[0063] A linkage 53 is provided between the timing belt assembly 51 and the side connector 43. One end of the linkage 53 is fixed to the timing belt 513, and the other end is fixed to the side connector 43. The reciprocating motion of the timing belt 513 enables the linear movement of the side connector 43 and the drawer 4.

[0064] Specifically, such as Figure 8 , 9 As shown, the linkage component 53 includes a linkage plate 531 and a fixing block 532. The linkage plate 531 is a sheet structure with a first fixing part 5311 connected to the synchronous belt 513 and a second fixing part 5312 connected to the side connecting member 43. The first fixing part 5311 is bent and disposed at the bottom of the second fixing part 5312, and the two are arranged vertically.

[0065] The first fixing part 5311 has a tooth groove 5313 adapted to the tooth surface of the timing belt 513 and at least one first connecting hole 5314 for connecting the fixing block 532. The fixing block 532 is L-shaped and has a second connecting hole 5321 corresponding to the first connecting hole 5314 and a slot 5322 for inserting the first fixing part 5311. A fastener (screw) is provided between the first connecting hole 5314 and the second connecting hole 5321. The first fixing part 5311 is installed on one side of the tooth surface of the timing belt 513, and part of the tooth shape of the tooth surface of the timing belt 513 is embedded in the tooth groove 5313. The fixing block 532 is installed on the non-tooth surface side of the timing belt 513. At the same time, the end of the first fixing part 5311 is inserted into the slot 5322 of the fixing block 532. The inner end of the first fixing part 5311 is fixed to the fixing block 532 by fasteners (screws, etc.), thereby realizing a reliable connection between the linkage 53 and the timing belt 513. In this embodiment, the connection structure between the linkage 53 and the timing belt 513 can prevent slippage, making the transmission more reliable and precise; at the same time, it will not damage the timing belt.

[0066] In addition, the length of the timing belt 513 is matched with the stroke of the drawer 4, and the mounting point of the first fixing part 5311 on the timing belt 513 is always located between the driving pulley 511 and the driven pulley 512. Therefore, during the movement, it will not interfere with the driving pulley 511 or the driven pulley 512.

[0067] The second fixing part 5312 is provided with a positioning protrusion 5316 and at least one first mounting hole 5315, with the positioning protrusion 5316 preferably arranged vertically. The tail of the side connector 43 is provided with a positioning groove 431 that mates with the positioning protrusion 5316 and a second mounting hole 432 corresponding to the first mounting hole 5315. During installation, the positioning protrusion 5316 is first inserted into the positioning groove 431, and then the first mounting hole 5315 and the second mounting hole 432 are fixedly connected by screws, thereby achieving a reliable connection between the linkage 53 and the side connector 43.

[0068] Optionally, a limiting member 44 is provided at the tail of the side connector 43. The limiting member 44 can be integrally or separately mounted on the side connector 43. To reduce costs, in this embodiment, the side connector 43, the slide rail fixing beam 124, the front vertical beam 122, and the rear vertical beam 123 are all C-shaped profiles. The limiting member 44 is separately mounted on the side connector 43 by screws. A first micro switch 54 is provided at the front end of the furnace box 1. When the drawer 4 reaches the open position, the limiting member 44 triggers the first micro switch 54 and controls the motor 52 to stop. At the same time, the interaction between the first micro switch 54 and the limiting member 44 can also prevent the drawer 4 from being opened further.

[0069] In addition, at least one pair of door lock components 45 are provided on the drawer door 42, and a corresponding lock hole 121 is provided on the front panel 125 of the oven box 1. A second micro switch (not shown in the figure) is provided in the lock hole 121. When the drawer 4 reaches the closed position, the door lock component 45 contacts the second micro switch and controls the motor 52 to stop.

[0070] In this embodiment, there are two ways to control the action of drawer 4: one is to drive it through the drawer open button and drawer close button on the operation panel 7; the other is for the user to push and pull it manually. After the system senses the direction of movement of drawer 4, it will start motor 52 to work and open or close drawer 4 accordingly until the first micro switch 54 or the second micro switch is triggered, at which point motor 52 will stop working.

[0071] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
