[0001] The invention relates to the technical field of kitchen steam utilization, in particular to an energy-saving utilization recovery device for waste steam from a commercial kitchen. Background Art

[0002] The commercial kitchen is the core area of ​​the catering industry. It integrates cooking and meal preparation and is equipped with efficient cooking equipment and professional kitchen utensils. It shoulders the heavy responsibility of food production and must ensure that the ingredients are fresh, the operations are standardized, and the hygiene standards are up to standard. The design of commercial kitchens focuses on process optimization and improving meal delivery efficiency, while also paying attention to energy conservation and safety. Here, chefs use their superb skills to transform ingredients into delicious dishes to meet the diverse needs of customers, which is the key to the successful operation of a catering company.

[0003] Commercial kitchens have a large workload and carry out a large number of steaming processes, so a lot of steam is generated. Under normal circumstances, this steam is directly discharged into the kitchen, which not only easily leads to large amounts of water mist and humidity in the kitchen, but also the steam and its residual heat cannot be effectively utilized, which is not conducive to energy conservation and environmental protection. Therefore, we propose a commercial kitchen waste steam energy-saving recycling device. Summary of the invention

A heat-conducting pipe with a copper tube on the outer ring is arranged in an outer shell, and an air inlet cylinder that can be covered on the steamer by a cover is arranged. The high-temperature steam generated during the use of the steamer can be collected and transmitted to the copper tube to heat the clean water in the heat-conducting pipe. Not only the waste heat of the steam can be utilized, but also the condensed water generated by the steam can be collected for mopping the floor and other aspects, thereby achieving the purpose of energy saving and solving the problems raised in the background technology.

[0009] As a preferred embodiment of the present invention, an outer ring plate is arranged around the lower outer ring of the screw barrel, and when the screw barrel is screwed into the screw mouth, the outer ring plate abuts against the bottom surface of the air inlet cylinder.

[0010] By adopting the above technical solution, the purpose of limiting the position of the screw barrel when it is screwed into the screw mouth can be achieved.

[0011] As a preferred embodiment of the present invention, an inner ring plate is fixed around the inner ring surface of the cover, and the inner ring plate is located at a lower position on the inner side of the cover.

[0012] By adopting the above technical solution, when the cover is placed on the steamer, the upper outer ring of the steamer abuts against and is supported on the bottom surface of the inner ring plate.

[0013] As a preferred embodiment of the present invention, blades are rotatably installed at the lower part of the exhaust pipe, and the blades are drivingly connected to electrodes installed on the upper surface of the exhaust pipe.

[0014] By adopting the above technical solution, when in use, the motor starts to drive the blades to rotate and blow air toward the outlet pipe, so that negative pressure is formed at the exhaust pipe position, making it easy to inhale high-temperature steam through the copper tube.

[0015] As a preferred embodiment of the present invention, the copper tube is connected to a secondary tube above the copper tube, which is communicated with the inside of the copper tube and penetrates to the top of the outer shell, and a sealing cover is sealed on the outer ring of the secondary tube.

[0016] By adopting the above technical solution, the auxiliary pipe can be connected to the steam exhaust pipe of equipment such as an electric furnace or a steam box, and the high-temperature steam of other equipment can also be used.

[0017] As a preferred embodiment of the present invention, a U-shaped tube is provided on the water outlet pipe, and the U-shaped tube and the water outlet pipe are connected to form an integral structure.

[0018] By adopting the above technical solution, the U-shaped tube can play a role of water sealing to prevent steam from leaking from the bottom water outlet pipe.

[0019] As a preferred embodiment of the present invention, the bottom of the heat-conducting pot is connected to a drain pipe which is in communication with the interior of the heat-conducting pot and penetrates to the outside, and a first valve is installed on the drain pipe.

[0020] By adopting the above technical solution, during cleaning, water or sewage in the heat-conducting pot is discharged from the drain pipe.

[0021] As a preferred embodiment of the present invention, a second valve is installed on the air intake pipe, and the second valve is connected to the air intake pipe.

[0022] By adopting the above technical solution, when the steamer is not in use and the auxiliary pipe is used alone to inhale steam, the second valve can be used to seal the air inlet pipe.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1. The technical solution of the present application is to place a heat-conducting pipe with a copper tube on the outer ring in an outer shell, and to arrange an air inlet cylinder that can be covered on the steamer by a cover, so as to collect the high-temperature steam generated during the use of the steamer and transmit it to the copper tube to heat the clean water in the heat-conducting pipe. The heated clean water can be used for making soup, thereby reducing the consumption of gas.

[0036] See also Figure 1-5 The present invention provides a technical solution: a commercial kitchen waste steam energy-saving utilization recovery device, including a shell 1, a heat-conducting pot 2, an air inlet pipe 3, a copper tube 4, an exhaust pipe 5 and a dust cover 6. The four corners of the bottom of the shell 1 are vertically supported by support legs 11, and the support legs 11 at the four corners have the same height to achieve stable horizontal support for the shell 1.

[0037] The heat-conducting pot 2 is fixed inside the outer shell 1, and the heat-conducting pot 2 is placed at the center of the outer shell 1, and the top of the heat-conducting pot 2 is exposed to the outside of the outer shell 1, which is convenient for adding clean water to the inside of the heat-conducting pot 2 or scooping it for use. The bottom of the heat-conducting pot 2 is connected to a drain pipe 21 connected to the inside of the heat-conducting pot 2, and the drain pipe 21 extends downward to the outside of the outer shell 1, and a first valve 211 is installed on the drain pipe 21. When the valve is opened, the clean water stored in the heat-conducting pot 2 can be discharged, or when the inside of the heat-conducting pot 2 is cleaned, the sewage during cleaning can be discharged.

[0038] In order to collect and utilize high-temperature steam, a cover 32 connected to the interior of the air inlet cylinder 3 is provided below the air inlet cylinder 3, and a first handle 31 is also provided in the middle of the surface of the air inlet cylinder 3. When in use, the air inlet cylinder 3 can be picked up by the first handle 31, and then it can be supported and placed above the steamer. An inner ring plate 323 is fixed around the inner surface of the cover 32. The inner ring plate 323 is located at the lower position of the inner side of the cover 32. The inner diameter of the cover 32 is slightly larger than the outer diameter of the steamer. When the cover 32 is placed on top of the steamer, the upper outer extension support of the steamer contacts the bottom surface of the inner ring plate 323, so that the cover 32 is placed around the top of the steamer. The steam generated when the steamer is in use will enter the air inlet cylinder 3 through the cover 32.

[0039] A copper tube 4 is arranged around the outer circle of the heat-conducting pot 2. The copper tube 4 is spirally attached to the outer circle of the heat-conducting pot 2, and the copper tube 4 is located on the inner side of the outer shell 1. The upper part of the copper tube 4 is connected with an air inlet pipe 41 that penetrates to the outside of the outer shell 1. The air inlet pipe 41 is connected to the upper interior of the air inlet cylinder 3, and the exhaust cylinder 5 is arranged on the upper side of the outer shell 1. The bottom of the exhaust cylinder 5 is connected with an exhaust pipe 51 that is connected to the interior thereof. The exhaust pipe 51 is connected to the lower interior of the copper tube 4. The upper side of the exhaust cylinder 5 is also connected with an air outlet pipe 54 that is connected to the interior thereof. The high-temperature steam is collected by the air inlet cylinder 3 and can enter the copper tube 4 through the air inlet pipe 41, so as to heat the clean water in the heat-conducting pot 2. Then the steam enters the exhaust cylinder 5 from the exhaust pipe 51, and then is discharged from the air outlet pipe 54. When the kitchen processes soup food later, the heated clean water can be directly scooped, saving gas used to boil clean water.

[0040] A water outlet pipe 42 is also connected to the bottom of the copper tube 4 and is connected to the interior thereof, and the water outlet pipe 42 extends to the outside of the outer shell 1. When high-temperature steam generates condensed water through the inside of the copper tube 4, the condensed water will flow downward under the action of gravity, and finally be discharged to the outside from the water outlet pipe 42. The condensed water can be collected in a bucket and used for mopping the floor or wiping items.

[0041] In addition, a U-shaped tube 421 is provided on the water outlet pipe 42. The U-shaped tube 421 is connected to the water outlet pipe 42 as an integral structure. The condensed water will first accumulate in the U-shaped tube 421 to form a water seal structure, so that when the high-temperature steam passes through the inside of the copper tube 4, it will not leak out from the water outlet pipe 42. Only when the condensed water enters the U-shaped tube 421 again, the excess condensed water will be discharged outward.

[0042] Since there are commonly used equipment such as water boilers and steamers that generate steam in commercial kitchens, in order to effectively utilize this part of high-temperature steam, a sub-pipe 43 connected to the interior of the copper tube 4 is connected to the upper left side of the copper tube 4. The sub-pipe 43 extends to the outside of the upper part of the outer shell 1 and can be connected to the steam exhaust pipe of the water boiler or steamer through a pipeline. The steam can also enter the copper tube 4 through the sub-pipe 43. When the sub-pipe 43 is idle and not in use, the outer ring of the sub-pipe 43 can be sealed with a sealing cover 431.

[0043] A second valve 411 is also installed on the air intake pipe 41, and the second valve 411 is connected to the air intake pipe 41. When the steamer is not in use and a steam generating device such as a water boiler or a steamer is used alone, the second valve 411 can be closed to seal the air intake pipe 41 to avoid the intake of cold air from the air intake cylinder 3. Similarly, in order to achieve the purpose of sealing the auxiliary pipe 43 when the steam generating device such as a water boiler or a steamer is not in use, the above-mentioned sealing cover 431 can also be replaced by a valve to make it more convenient to use (not shown in the figure).

[0044] Since the steam pressure discharged from the steamer or steam generating equipment is relatively low, there is a problem of small amount of steam passing through the copper tube 4 or backflow. Therefore, a blade 52 is rotatably installed at the lower part of the exhaust pipe 5. The blade 52 is transmission connected to the electrode installed on the upper surface of the exhaust pipe 5. When in use, the motor 53 is started to drive the blade 52 to rotate. When the blade 52 rotates, it blows air in the direction of the upper air outlet pipe 54, thereby forming a negative pressure under the exhaust pipe 5, which is conducive to the high-temperature steam entering the copper tube 4 from the air inlet pipe 41 or the auxiliary pipe 43, and then smoothly passing through the copper tube 4 and flowing toward the exhaust pipe 51, and finally entering the exhaust pipe 5 and being discharged outward from the air outlet pipe 54.

[0045] A dust cover 6 is also provided, which can be covered on the top of the heat-conducting pot 2 to seal it. A second handle 61 is fixed in the middle position of the surface of the dust cover 6, and the dust cover 6 can be conveniently picked up and used by the second handle 61. When the cover 32 is above the heat-conducting pot 2, dust is prevented from falling into the clean water.

[0046] Different steamers have different diameters. In order to make the device adaptable to different steamers, a screw barrel 321 with a threaded outer ring is connected to the top of the cover 32, and a leakage port connected to the interior of the air inlet cylinder 3 is provided at the bottom of the air inlet cylinder 3. The cover 32 is connected to the bottom of the air inlet cylinder 3 by screwing the screw barrel 321 into the screw port 33 at the bottom of the air inlet cylinder 3, and the cover 32 is removable. Therefore, various covers 32 with different diameters can be equipped, and all covers 32 are connected with a screw barrel 321 of the same size at the top. According to the different diameters of the steamers, covers 32 with different diameters can be replaced and connected to the bottom of the air inlet cylinder 3 to achieve the purpose of matching use and ensure that the equipment can be adapted to steamers of different diameters.

[0047] At the same time, an outer ring plate 322 is arranged around the outer circle below the screw barrel 321. When the screw barrel 321 is screwed into the threaded mouth 33, the outer ring plate 322 contacts the bottom surface of the air intake cylinder 3. The above arrangement can limit the depth of the screw barrel 321 being screwed into the air intake cylinder 3, thereby preventing the screw barrel 321 from being screwed in too deep.

[0048] When in use, add a sufficient amount of clean water into the heat conducting pot 2, and then lift the dust cover 6 with the second handle 61 to cover the top of the heat conducting pot 2. When using the steamer to steam food, the second handle 61 can be used to lift the air inlet cylinder 3, and the cover 32 below it is placed on the top of the steamer and the second valve 411 is opened. When steaming food, the motor 53 is connected to the power supply and started, driving the blades 52 to rotate and blow air toward the air outlet pipe 54. By utilizing the negative pressure, the high-temperature steam generated in the steamer can smoothly enter the air inlet cylinder 3, and then flow into the copper tube 4 along the air inlet pipe 41, and finally flow upward from the exhaust pipe 51 into the exhaust cylinder 5 and be discharged from the air outlet pipe 54. When the high-temperature steam flows in the copper tube 4, it can heat the clean water in the heat conducting tube and preheat it to a higher temperature. After that, the dust cover 6 can be removed and the heated steam can be directly scooped out from the heat conducting pot 2 The clean water in the heat-conducting pot 2 is used for cooking. When the clean water in the heat-conducting pot 2 is less, it needs to be replenished in time, so that less gas can be used to boil the clean water, which achieves the purpose of saving gas. The condensed water generated by the high-temperature steam flowing in the copper tube 4 finally passes through the U-shaped tube 421 and is discharged from the water outlet pipe 42. It can be collected with a water cylinder for wiping or mopping. In addition, the sealing cover 431 on the auxiliary pipe 43 can be unplugged, and the auxiliary pipe 43 and the steam discharge pipe of other heating equipment in the kitchen (such as a water boiler, a steamer) can be connected with a pipe. High-temperature steam can also be supplied to the copper tube 4. When the air intake cylinder 3 is not placed on a working steamer for use, the second valve 411 needs to be closed to avoid inhaling cold air from the air intake cylinder 3. When the heat-conducting pot 2 is cleaned, the first valve 211 can be unscrewed to discharge the water in the heat-conducting pot 2 from the heat-conducting pot 2.
