[0032] As Figure 4As shown, the microwave lifting device is installed in the microwave base 23 to drive the microwave platform plate 21 and the lower microwave generator 5 to move up and down, which comprises a microwave motor base 32, a microwave motor 31, a microwave transmission screw rod 26, a first microwave lifting connecting rod 24, a microwave horizontal slider 25 and a second microwave lifting connecting rod 24. The microwave motor base 32 and the microwave motor 31 are installed at the rear side of the microwave base 23. The microwave transmission screw rod 26 is installed on the microwave motor base 32 and is in transmission connection with the microwave motor 31. The microwave transmission screw rod 26 is connected with the microwave horizontal slider 25 through a copper nut. The microwave horizontal slider 25 is hingedly provided with the first microwave lifting connecting rod 24 at both ends. The upper ends of the two first microwave lifting connecting rods 24 are hingedly connected to the platform supports 28 at both sides of the front end of the microwave platform plate 21.

[0033] In specific use, when the microwave motor 31 drives the microwave horizontal slider 25 to move horizontally forward through the microwave transmission screw rod 26, the microwave horizontal slider 25 drives the lower ends of the two hingedly connected first microwave lifting connecting rods 24 to move forward synchronously. Since the first microwave lifting connecting rods 24 are positionally constrained at the hinged connection with the second microwave lifting connecting rods 24, the upper ends of the first microwave lifting connecting rods 24 drive the microwave platform plate 21 to move upward. Conversely, when the microwave motor 31 drives the microwave horizontal slider 25 to move horizontally backward through the microwave transmission screw rod 26, the first microwave lifting connecting rods 24 linked with the microwave horizontal slider 25 drive the microwave platform plate 21 to move downward, thereby realizing the automatic operation of the microwave platform plate 21 lifting.

[0034] As shown in the drawings, Figure 3 As shown, the microwave steam assembly 7 comprises an integrated water injection head push plate 10, a nozzle assembly 15 and an air suction cover 8.

The nozzle 20 is fixedly connected with the cleaning water pipe 19 through a plurality of positioning pins at the bottom outside. The air suction cover 8 is rectangular and is sleeved on the outer periphery of the cleaning water pipe 19. The bottom of the air suction cover 8 is open and the air suction pipe joint 9 is arranged at the side. The air suction pipe joint 9 is connected with an air suction device to quickly suck out the gas in the microwave heating chamber to realize air replacement.

[0035] Specifically, copper pillars 11 for limiting are installed on the bottom surface of the four corners of the water injection head push plate 10. A nozzle guide rod 12 is also installed on each side of the top of the suction hood 8. The upper part of the nozzle guide rod 12 is movably installed with the water injection head push plate 10. A nozzle limiting block 13 is provided on the top of the nozzle guide rod 12. A tension spring assembly (not shown) is provided between the suction hood 8 and the water injection head push plate 10. The suction hood 8 is fixedly installed on the upper microwave generator 4. When there is an external force, the water injection head push plate 10 and the nozzle assembly 15 can move up and down relative to the suction hood 8 along the nozzle guide rod 12, and the tension spring assembly provides buffering or restoring force. When there is no external force, they remain balanced on the upper microwave generator 4. The process is as follows: the boxed food in the frozen state is pushed upward by the microwave lifting device to move the microwave platform plate 21. After contacting the nozzle assembly 15, the top cover of the boxed food is punctured. Steam is then injected into the nozzle assembly 15 to realize the rapid defrosting and heating of the boxed food.

A pressure plate 49 is mounted on the scraper 48, which facilitates the food pushing action. During the food pushing and returning process, the pressure plate 49 on the scraper 48 also scrapes away water from the microwave platform plate 21 and pushes it into the water receiving plate 22 for outward discharge, achieving a cleaning effect on condensed or accumulated water on the surface of the microwave platform plate 21.

[0039] like Figure 6As shown, the synchronous belt conveying device includes a push plate motor 32, a drive pulley 35, a sliding table tension pulley 34, a synchronous pulley 43, and a synchronous belt 42.

[0043] Specifically, when the lifting platform motor 62 drives the lifting platform lower slider 54 to move horizontally forward along the two lower guide rods 56 through the lifting platform screw rod 53, the lifting platform lower slider 54 drives the lower ends of the two hingedly connected first lifting connecting rods 58 to move forward synchronously, and since the first lifting connecting rod 58 is positionally constrained at the middle hingedly connected part of the second lifting connecting rod 58, the upper end of the first lifting connecting rod 58 pushes the lifting platform panel 52 and the water receiving cup 50 thereon to lift upward, and at the same time, the lifting platform panel 52 drives the lifting platform upper slider 55 and the upper ends of the second lifting connecting rods 58 on the two sides to move horizontally forward along the two upper guide rods 57, and the lower ends of the second lifting connecting rods 58 remain unchanged in position in the front part of the lifting base 51; conversely, when the lifting platform motor 62 drives the lifting platform lower slider 54 to move horizontally backward along the two lower guide rods 56 through the lifting platform screw rod 53, the first lifting connecting rod 58 linked with the lifting platform lower slider 54 pushes the lifting platform panel 52 and the water receiving cup 50 thereon to move downward.
