[0003] Existing steam heating cabinets include a cabinet and a base. The base contains a steam generator and a water tank. The water tank supplies water to the steam generator through pipes, thereby enabling the steam generator to produce steam and deliver it to the cabinet to heat the food.

[0004] When existing steam cabinets are in use, the steam is discharged outwards without pressure relief, resulting in a large amount of water vapor splashing outwards, which affects their operation. Utility Model Content

[0005] The purpose of this invention is to provide a heat recovery and recycling steam cabinet to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A heat recovery and recycling steam cabinet includes a cabinet frame, on which multiple steam trays are arranged sequentially from top to bottom, and each steam tray is equipped with a heat circulation system.

[0008] The heat circulation system includes a heating box, which is provided with a first circulation zone and a second circulation zone. The second circulation zone is located at the bottom of the first circulation zone. The heating box is provided with a cold water inlet and a hot water outlet, wherein the cold water inlet is located in the first circulation zone and the hot water outlet is located in the second circulation zone; cold water flows from the first circulation zone into the second circulation zone and then is discharged.

[0012] Furthermore, the first circulation zone also has a pressure relief groove located at the top of the wake heating groove, the bottom of the pressure relief groove is connected to the wake heating groove, and the exhaust port is formed at the top of the pressure relief groove.

[0013] Furthermore: the square tube structure includes a top plate, a bottom plate, and a guide tube arranged between the top plate and the bottom plate. There are multiple guide tubes, and two adjacent guide tubes are arranged at intervals. The top plate and the bottom plate are respectively formed with flow cavities for liquid flow. The guide tubes are connected to the flow cavities of the top plate and the bottom plate. The top plate is connected to the other end of the top corrugated tube.

[0014] Furthermore, the square tube structure also has a square tube liquid inlet and a square tube liquid outlet. The square tube liquid inlet is located on the top plate and is connected to the other end of the top corrugated pipe of the wake heating tank.

[0015] Furthermore: the second circulation zone is formed with multiple spaced bottom heating tanks, and two adjacent bottom heating tanks are connected. The second circulation zone is provided with bottom corrugated pipes that meander along the multiple bottom heating tanks.

[0039] The present invention will now be described in detail with reference to the accompanying drawings.

[0040] like Figure 1-4As shown, a heat recovery and recycling steam cabinet includes a cabinet frame 1. Multiple steam trays are arranged sequentially from top to bottom on the cabinet frame 1. The steam trays are divided into a first steam tray 11, a second steam tray 12, and a third steam tray 13. Each steam tray has an opening 14, and a cabinet door 15 is hinged to the opening 14. A silicone gasket 16 is installed on the inner wall of the cabinet door 15 to seal against the opening 14. When the cabinet door 15 is hinged to the opening 14, the silicone gasket 16 formed on the cabinet door 15 can seal against the edge of the opening 14 to achieve a sealed closure and prevent steam leakage from the steam tray.

[0041] The steamer is equipped with a heat circulation system 2; the heat circulation system 2 includes a heating box 21. The heating box 21 is provided with a first circulation zone 3 and a second circulation zone 5, with the second circulation zone 5 located at the bottom of the first circulation zone 3. The heating box 21 is provided with a cold water inlet 22 and a hot water outlet 23, wherein the cold water inlet 22 is located in the first circulation zone 3, and the hot water outlet 23 is located in the second circulation zone 5. Cold water enters the first circulation zone 3, passes through the second circulation zone 5, and is then discharged. The heating box 21 is equipped with a circulating steam inlet 24 and a circulating steam outlet 25. The circulating steam inlet 24 is located in the second circulation zone 5, and the circulating steam outlet 25 is located in the first circulation zone 3. The circulating steam inlet 24 is connected to the steamer. The steam discharged from the steamer enters the second circulation zone 5, passes through the first circulation zone 3, and is discharged. Since the cold water inlet 22 is located in the first circulation zone 3, the temperature of the steam gradually decreases after flowing from the second circulation zone 5 to the first circulation zone 3. The temperature of the cold water gradually increases after flowing from the cold water inlet 22 to the hot water outlet 23. After multiple steam heating processes, the cold water can be heated to become hot water. The steam is recovered and recycled, saving gas usage.

[0042] Specifically, the first circulation zone 3 is provided with a wake heating structure 31 and a square tube structure 4 from top to bottom. The wake heating structure 31 includes a wake heating trough 32 formed in the first circulation zone 3. A top corrugated pipe 33 is arranged meanderingly along the length of the wake heating trough 32. One end of the top corrugated pipe 33 is connected to the cold water inlet 22; the other end of the top corrugated pipe 33 is connected to the square tube structure 4 at the bottom. Cold water enters the first circulation zone 3 through the cold water inlet 22, flows sequentially in the top corrugated pipe 33, and then enters the square tube structure 4.

[0043] Specifically, the square tube structure 4 includes a top plate 41, a bottom plate 42, and a guide pipe 43 arranged between the top plate 41 and the bottom plate 42; the top plate 41 and the bottom plate 42 are respectively formed with flow chambers 44 for liquid flow, the guide pipe 43 is connected to the flow chambers 44 of the top plate 41 and the bottom plate 42, and the top plate 41 is connected to the other end of the top corrugated pipe 33 so that water from the top corrugated pipe 33 can enter the square tube structure 4.

[0044] Preferably, the square tube structure 4 is further formed with a square tube liquid inlet 47 and a square tube liquid outlet 48. The square tube liquid inlet 47 is disposed on the top plate 41 and is connected to the other end of the top corrugated pipe 33 of the tail flow heating tank 32. The top corrugated pipe 33 located in the tail flow heating tank 32 introduces the pre-heated warm water into the top plate 41 in the square tube structure 4 through the square tube liquid inlet 47. After passing through the top plate 41, the guide pipe 43 and the bottom plate 42 in sequence, the water is discharged into the bottom corrugated pipe 52 of the second circulation zone 5 through the square tube liquid outlet 48.

[0045] The second circulation zone 5 has multiple spaced-apart bottom heating tanks 51, and a bottom corrugated pipe 52 is arranged meandering along the multiple bottom heating tanks 51. One end of the bottom corrugated pipe 52 is connected to the hot water outlet 23, and the other end is connected to the square liquid outlet 48. The warm water after passing through the first circulation zone 3 enters the second circulation zone 5, flows through the bottom heating tanks 51, and is discharged from the hot water outlet 23.

[0046] The circulating steam inlet 24 is located within the second circulation zone 5, allowing steam to flow along the length of the bottom heating tank 51 and the bottom corrugated pipe 52. The closer the water in the bottom corrugated pipe 52 is to the hot water outlet 23, the higher the water temperature in that area, as steam enters the bottom heating tank 51 within the second circulation zone 5 from near the hot water outlet 23. This process is called "air-filled water." The hot water that has passed through the "air-filled water" process is then fed into the steamer through the hot water outlet 23, thus achieving recycling.

[0047] Preferably, there are multiple bottom heating tanks 51, and two adjacent bottom heating tanks 51 are connected. After steam enters the bottom heating tank 51, it flows along the multiple bottom heating tanks 51 in sequence. The corrugated pipe is usually made of stainless steel, which has good thermal conductivity. The bottom corrugated pipe 52 located in the bottom heating tank 51 absorbs heat from the steam, and the water in the bottom corrugated pipe 52 can be heated.

[0048] The square tube structure 4 also has a square tube steam inlet 45 and a square tube steam outlet 45. The square tube steam outlet 45 is connected to the tail flow heating tank 32, and the square tube steam inlet 45 is connected to the bottom heating tank 51. Steam enters the second circulation zone 5 from the first circulation zone 3, and the temperature gradually decreases. Then, the steam passes through multiple guide pipes 43 in sequence. The hot water located on the top plate 41 can flow synchronously to the bottom plate 42 through the guide pipes 43. When the steam enters the square tube structure 4, it will pass through the gaps between the multiple guide pipes 43, further heating the warm water located in the guide pipes 43. The above steps are called "water-encased gas".

[0049] Preferably, there are multiple guide pipes 43, with adjacent guide pipes 43 arranged at intervals. When steam enters the square tube structure 4 from the first circulation zone 3, it will pass through the gaps between the multiple guide pipes 43. When passing through the gaps, the steam located in the guide pipe 43 will absorb heat, achieving further heating. In addition, after these steam come into contact with the guide pipes 43, their pressure will continuously decrease, gradually depressurizing.

[0050] The second circulation zone 5 is also equipped with a pressure relief structure for steam depressurization, which includes multiple spaced exhaust ports 35 for steam discharge.

[0051] The wake heating tank 32 is connected to the square steam outlet 45, and the steam flows along the length of the wake heating tank 32. The first circulation zone 3 is also formed with a pressure relief tank 34 located at the top of the wake heating tank 32. The bottom of the pressure relief tank 34 is connected to the wake heating tank 32, and the exhaust port 35 is formed at the top of the pressure relief tank 34. After the steam is recycled through the first circulation zone 3 and the second circulation zone 5, the temperature of the steam continuously decreases and the steam is gradually depressurized. Then, it is further depressurized through the contact of the exhaust port 35 and finally discharged to the outside.

[0052] Steam discharged from the square tube structure 4 continues to enter the tail flow heating tank 32 through the square tube steam outlet 45, and comes into contact with the top corrugated pipe 33. At this time, the temperature of the steam gradually decreases. The water in the top corrugated pipe 33 is the cold water that has just been introduced. After absorbing heat, the top corrugated pipe 33 further heats the cold water to form warm water, making full use of the discharged steam and reducing energy consumption. The above steps are called "water-encased steam".

[0053] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0054] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
