Description

Technical Field

[0001] This utility model relates to the field of steamer water tank technology, and in particular to a breeding and hatching device with disinfection and cleaning functions. Background Technology

[0002] As a core piece of equipment for steaming food in the catering industry, the type of heating energy used in steamers is a key technical characteristic that determines the equipment's operating efficiency, operating costs, and applicable scenarios. Based on the different heating energy supply methods, steamers can be divided into two main categories: electric steamers and gas steamers. From the perspective of practical application performance and economic analysis, electric steamers are generally less efficient in terms of heat output compared to gas steamers due to factors such as power conversion efficiency and power supply limitations. Furthermore, the combined cost of electricity and long-term energy consumption results in significantly higher overall costs for users compared to gas steamers. Based on the core needs of cost control and operational efficiency optimization, restaurants and other catering establishments currently prioritize gas steamers as their primary steaming equipment. By using gas as the core energy source, they effectively reduce energy consumption costs in daily operations and improve the cost-effectiveness of food processing.

[0003] The working principle of existing gas-fired steam cabinets is as follows: heat energy is released through the combustion of gas, and the heat is transferred to the water tank inside the cabinet through heat conduction and radiation. The water in the tank is heated and vaporized to produce high-temperature steam, which in turn uses the enthalpy of the steam to heat and steam the food inside the cabinet cavity, achieving both cooking and preservation. From a structural design perspective, the heating system of current mainstream gas-fired steam cabinets mainly consists of a burner installed at the bottom of the water tank. The burner generates a high-temperature flame by burning gas, which directly heats the bottom of the water tank. However, this traditional structural design has significant technical defects: on the one hand, the heat energy released by the burner is transferred to the water body only through a single contact surface at the bottom of the water tank, resulting in a limited heat conduction path and causing a large amount of heat energy to be lost to the external environment through radiation from the combustion chamber wall; on the other hand, the high-temperature flue gas generated by gas combustion is not effectively recovered and utilized, and a large amount of waste heat carried by the flue gas is directly emitted, further reducing the heat energy utilization rate; at the same time, the water body in the water tank is heated unevenly, with the water temperature rising faster in the area near the burner and lagging behind in the area away from it, which not only affects the stability of steam generation but also indirectly increases energy consumption; the above problems result in the existing gas steam cabinets having a low heat energy conversion efficiency (the proportion of gas combustion heat energy converted into steam heat energy) and a low heat energy utilization rate (the proportion of heat energy actually used for food heating to the total heat energy released by the gas), causing serious waste of gas energy. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose a steamer water tank that saves energy while improving work efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A steamer water tank includes a water tank shell, a combustion tube, an auxiliary combustion water pipe, and a dry-burning pipe. The combustion tube is coiled inside the water tank shell. The combustion tube has multiple connecting holes. The auxiliary combustion water pipe is connected to the connecting holes. The dry-burning pipe is connected to the combustion tube. The combustion tube has multiple exhaust holes for discharging high-temperature air. The combustion tube includes a first tube body, a second tube body, and a combustion bend. The first tube body is connected to one end of the combustion bend, and the second tube body is connected to the other end of the combustion bend. The connecting holes are formed on the first and second tube bodies. The auxiliary combustion water pipe communicates with the connecting holes. The dry-burning pipe is connected to the first tube body. Both the first and second tube bodies have exhaust holes.

[0007] Preferably, the water tank of the steamer described above, after the first pipe body, the second pipe body and the combustion bend are connected, form a "U" shaped pipe.

[0008] Preferably, in the water tank of the steamer described above, the connecting holes are evenly distributed along the length direction of the first tube and the second tube, and the center distance between two adjacent connecting holes is 30-80mm, and the diameter of the connecting holes is 15-30mm.

[0009] Preferably, in the steamer water tank described above, the number of combustion-supporting water pipes is the same as the number of connecting holes, and the combustion-supporting water pipes are arranged perpendicularly to the first pipe body and the second pipe body, with one end of the combustion-supporting water pipe away from the connecting hole extending to the middle region of the inner cavity of the water tank shell.

[0010] Preferably, in the above-mentioned steamer water tank, the end of the dry-burning tube away from the first tube body extends to the outside of the water tank shell, and a sealing heat insulation sleeve is provided at the penetration point between the dry-burning tube and the water tank shell, the sealing heat insulation sleeve being made of high-temperature resistant ceramic material.

[0011] Preferably, in the steamer water tank described above, the first tube body, the second tube body, the combustion bend, the combustion-aiding water pipe, and the dry-burning pipe are all made of 444 stainless steel.

[0012] The beneficial effects of this utility model are:

[0013] (1) Through the structural design of connecting the combustion water pipe and the combustion fire pipe, on the one hand, water can enter the interior of the combustion water pipe through the connecting hole, forming a heating mode of "double heating inside and outside the pipe" to accelerate the vaporization rate of the water; on the other hand, the combustion water pipe is evenly distributed in the inner cavity of the water tank, which can break the limitation of natural convection of water, promote the circulation of water in the water tank, avoid the phenomenon of local water temperature being too high or too low, and achieve uniform heating of water; at the same time, the dry burning pipe is connected to the first pipe body, which can quickly heat up in the early stage of ignition, provide a stable preheating environment for gas combustion, ensure that combustion is sufficient and continuous, and thus ensure the continuity and uniformity of steam generation, solve the problem of large fluctuations in steam output and low steaming efficiency of traditional steamers, and greatly shorten the steaming time of food.

[0014] (2) Since the combustion tube includes a first tube body, a combustion bend tube, and a second tube body, they are arranged in a distributed manner in the inner cavity of the water tank shell, which increases the contact area between the combustion tube and the water body. At the same time, the combustion water pipe is connected to the first tube body and the second tube body through the connecting hole, which further extends the heat conduction path, so that the heat energy generated by the combustion of gas can be transferred to the water body in a multi-dimensional and all-round way through the combustion tube wall and the combustion water pipe, avoiding the heat conduction limitation caused by traditional single bottom heating. In addition, the exhaust hole opened in the combustion tube can discharge the high-temperature air after combustion to different areas of the inner cavity of the water tank. The high-temperature air releases waste heat while forming a disturbance in the water body, realizing the dual heat exchange mode of "tube wall heat conduction + high-temperature air waste heat radiation", which greatly reduces the loss of heat energy to the external environment. Compared with the traditional structure, the heat energy conversion efficiency is increased by more than 30%, the heat energy utilization rate is increased by more than 25%, and the waste of gas energy is effectively reduced.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] like Figures 1-3As shown, a steamer water tank includes a water tank shell 11, a combustion tube 12, an auxiliary combustion water pipe 13, and a dry-burning pipe 14. The combustion tube 12 is coiled in the inner cavity of the water tank shell 11. The combustion tube 12 has multiple connecting holes. The auxiliary combustion water pipe 13 is connected to the connecting holes, and the dry-burning pipe 14 is connected to the combustion tube 12. The combustion tube 12 has multiple exhaust holes 15 for discharging high-temperature air. The combustion tube 12 includes a first tube body 16, a second tube body 17, and a combustion bend 18. The first tube body 16 is connected to one end of the combustion bend 18, and the second tube body 17 is connected to the other end of the combustion bend 18. Connecting holes are opened on the first tube body 16 and the second tube body 17. The auxiliary combustion water pipe 13 communicates with the connecting holes, and the dry-burning pipe 14 is connected to the first tube body 16. Both the first tube body 16 and the second tube body 17 have... It has an exhaust vent 15; through the structural design of connecting the combustion water pipe 13 and the combustion fire pipe 12, water can enter the interior of the combustion water pipe 13 through the connecting hole, forming a "double heating inside and outside the pipe" heating mode, which accelerates the vaporization rate of the water; on the other hand, the combustion water pipe 13 is evenly distributed in the inner cavity of the water tank, which can break the limitation of natural convection of water, promote the circulation of water in the water tank, avoid the phenomenon of local water temperature being too high or too low, and achieve uniform heating of water; at the same time, the dry burning pipe 14 is connected to the first pipe body 16, which can quickly heat up in the early stage of ignition, provide a stable preheating environment for gas combustion, ensure complete and continuous stable combustion, and thus ensure the continuity and uniformity of steam generation, solving the problems of large fluctuations in steam output and low steaming efficiency in traditional steamers, and greatly shortening the steaming time of food.

[0023] It is worth noting that, since the combustion tube 12 includes a first tube body 16, a combustion bend 18, and a second tube body 17, which are distributed within the inner cavity of the water tank shell 11, the contact area between the combustion tube 12 and the water is increased. Simultaneously, the combustion-supporting water pipe 13 is connected to the first tube body 16 and the second tube body 17 through a connecting hole, further extending the heat conduction path. This allows the heat energy generated by gas combustion to be transferred to the water in a multi-dimensional and all-round manner through the walls of the combustion tube 12 and the combustion-supporting water pipe 13, avoiding the heat conduction caused by traditional single bottom heating. Limitations; In addition, the exhaust port 15 opened in the combustion tube 12 can directionally discharge the high-temperature air after combustion to different areas of the water tank cavity. The high-temperature air releases waste heat while forming turbulence in the water, realizing a dual heat exchange mode of "tube wall heat conduction + high-temperature air waste heat radiation", which greatly reduces the loss of heat energy to the external environment, improves efficiency, and also avoids the emission of high-temperature exhaust gas into the air and pollutes the environment. Compared with the traditional structure, the heat energy conversion efficiency is increased by more than 30%, the heat energy utilization rate is increased by more than 25%, and the waste of gas energy is effectively reduced.

[0024] In this embodiment, the water tank of the steamer has a U-shaped pipe formed by connecting the first pipe body 16, the second pipe body 17, and the combustion bend 18. The U-shaped pipe structure allows the combustion tubes 12 to be symmetrically distributed in the inner cavity of the water tank shell 11. The first pipe body 16 and the second pipe body 17 are arranged in parallel and smoothly transition through the combustion bend 18. Compared with straight or irregular pipes, this extends the combustion path of the gas and the residence time of the high-temperature flue gas in the pipe, making the gas combustion more complete and the heat energy release more thorough. At the same time, the U-shaped layout allows the first pipe body 16, the second pipe body 17, and the combustion bend 18 to evenly cover the core heating area of ​​the water tank cavity, making the contact between the water and the pipe wall more balanced. This avoids water temperature differences caused by local heating concentration, ensures that the overall heating rate of the water in the water tank is consistent, thereby improving the stability and uniformity of steam generation and ensuring the consistency of food steaming effect.

[0025] In some embodiments of the steamer's water tank, the connecting holes are evenly spaced along the length of the first tube 16 and the second tube 17, with a center-to-center distance of 30-80 mm between adjacent connecting holes and a hole diameter of 15-30 mm. This even distribution of connecting holes along the length of the first tube 16 and the second tube 17 ensures that the combustion-supporting water pipes 13 connected to them form a uniform distributed layout within the water tank's interior. This guarantees that the heat energy released by the combustion tube 12 is synchronously transferred to all areas of the water body through the combustion-supporting water pipes 13, avoiding localized heat exchange concentrations or heat transfer blind spots. The 30-80mm adjacent center spacing design ensures the distribution density of the combustion-supporting water pipes 13, covering the core heating area inside the water tank, while avoiding pipe congestion caused by excessive spacing, ensuring smooth water flow between pipes; the 15-30mm aperture design achieves efficient connection between the combustion fire pipes 12 and the combustion-supporting water pipes 13, ensuring efficient heat transfer within the pipes and providing a reasonable channel for water circulation, making the overall heating rate of the water inside the water tank consistent, and the steam generation more stable and uniform, thereby ensuring the consistency of food steaming effect.

[0026] In some embodiments of the steamer's water tank, the number of combustion-supporting water pipes 13 is the same as the number of connecting holes, and the combustion-supporting water pipes 13 are arranged perpendicularly to the first pipe body 16 and the second pipe body 17. The end of the combustion-supporting water pipe 13 away from the connecting hole extends to the middle area of ​​the inner cavity of the water tank shell 11. The number of combustion-supporting water pipes 13 is consistent with the number of connecting holes, ensuring that each connecting hole is connected to one combustion-supporting water pipe 13, so that the heat energy released by the combustion fire tube 12 can be synchronously transferred to each combustion-supporting water pipe 13 through all connecting holes, avoiding the waste of heat energy caused by the idle connecting holes. Meanwhile, the combustion water pipe 13 is arranged perpendicularly to the first pipe body 16 and the second pipe body 17. Compared with the inclined or parallel arrangement, it can form a denser "horizontal + vertical" three-dimensional heat exchange network in the inner cavity of the water tank, which greatly increases the contact area between the pipe wall and the water. With the design of the combustion water pipe 13 extending to the middle area of ​​the inner cavity of the water tank shell 11, the heat exchange range extends from the periphery of the combustion fire tube 12 to the core area of ​​the inner cavity of the water tank. This breaks the heat transfer limitation of "high temperature in the near-pipe area and low temperature in the far-end area" in the traditional heating method, realizes the all-round and dead-angle transfer of heat energy to the water, and further improves the heat energy conversion efficiency and heating uniformity.

[0027] In some embodiments of the steamer's water tank, the end of the dry-burning tube 14 away from the first tube body 16 extends to the outside of the water tank shell 11, and a sealing heat insulation sleeve is provided at the penetration point between the dry-burning tube 14 and the water tank shell 11. The sealing heat insulation sleeve is made of high-temperature resistant ceramic material. The sealing heat insulation sleeve at the penetration point between the dry-burning tube 14 and the water tank shell 11 forms a double protection structure: on the one hand, the sealing heat insulation sleeve fits tightly against the outer wall of the dry-burning tube 14 and the inner wall of the penetration hole of the water tank shell 11, filling the assembly gap and effectively blocking the channel for water in the water tank to leak out through the penetration point, avoiding equipment failure or safety accidents caused by water leakage; on the other hand, the heat insulation performance of the sealing heat insulation sleeve can reduce the heat transferred from the dry-burning tube 14 to the penetration point of the water tank shell 11, reduce the rate of heat loss through the shell, and further improve the thermal energy utilization rate of the water tank.

[0028] In this embodiment, the water tank of the steamer is made of 444 stainless steel, including the first pipe 16, the second pipe 17, the combustion bend 18, the combustion-supporting water pipe 13, and the dry-burning pipe 14. 444 stainless steel has excellent high-temperature resistance and can operate stably in environments below 400℃ for extended periods. It can withstand the high-temperature conditions of components such as the combustion tube 12 and the combustion-supporting water pipe 13 during gas combustion (the local temperature of the dry-burning pipe 14 can reach over 300℃ during the initial ignition stage, while the pipe wall temperature remains between 150-250℃ during normal combustion). It will not deform, soften, or experience a significant decrease in strength. Furthermore, the thermal expansion coefficient and thermal conductivity of this material match the heating-cooling cycle of the steamer's water tank, making it less prone to cracking or fatigue damage during repeated heating and cooling processes. This ensures the long-term stability of the structural integrity and heat transfer efficiency of each pipe component, avoiding equipment failures due to insufficient material heat resistance and guaranteeing the reliability of the steamer's continuous operation.

[0029] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
