Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cooking oven structure, specifically a steam generating device based on a steam buffer pipe and a high-temperature cooking oven. Background Technology
[0002] In modern kitchens, steam ovens are widely used to meet diverse cooking needs. Steam ovens heat food quickly and evenly using steam, preserving its nutrients and original flavor while significantly reducing cooking time and increasing efficiency. Suitable for steaming various ingredients such as meats, vegetables, seafood, and pasta, steam ovens can easily handle everything from simple steamed buns and fish to complex Chinese stews or Western-style baking pre-processing. Furthermore, using a steam oven reduces reliance on traditional open flame cooking, minimizing kitchen fumes and creating a cleaner and safer kitchen environment.
[0003] Existing steamers typically have a steam generating assembly, which includes a water storage pipe and a heating pipe. Water from the water storage pipe flows into the heating pipe, is heated to boiling, and forms steam that enters the steaming chamber to heat the food. However, since the steam is directly generated by the heating pipe and enters the steaming chamber, it is difficult to maintain stable steam pressure and flow rate. This can easily lead to large fluctuations in steam pressure, resulting in inconsistent temperature distribution within the steaming chamber. Consequently, this unstable steam supply affects the uniformity of heating of the food, severely impacting the steaming effect and taste.
[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content
[0005] The existing steam generating assembly mentioned above includes a water storage pipe and a heating pipe. Water from the storage pipe flows into the heating pipe, is heated to boiling, and then forms steam which enters the cooking chamber to heat the food. However, since the steam is directly generated by the heating pipe and enters the cooking chamber, the steam pressure and flow rate are difficult to maintain stably, resulting in uneven temperature distribution within the cooking chamber and affecting the cooking effect and taste of the food. The technical solution adopted by this utility model to solve this problem is:
[0006] A steam generating device based on a steam buffer tube includes a steam generating device body, the steam generating device body including a water storage pipe for providing a water source, a first heating pipe connected to the water storage pipe for heating water to generate steam, a second heating pipe connected to the outside, and a steam buffer tube located between the first heating pipe and the second heating pipe for storing and stabilizing steam. The steam generated by the first heating pipe enters the steam buffer tube for storage and buffering, and then enters the second heating pipe for heating and is transmitted to the outside through the second heating pipe to heat food.
[0007] Furthermore, the steam buffer pipe is arranged horizontally, the first heating pipe is located below the steam buffer pipe and is arranged parallel to the steam buffer pipe, and a steam transmission pipe is provided between the steam buffer pipe and the first heating pipe.
[0008] Furthermore, the second heating tube is located below the steam buffer tube and is arranged parallel to the steam buffer tube. The second heating tube is provided with a first steam guide tube and a second steam guide tube. The second heating tube communicates with the steam buffer tube through the first steam guide tube and communicates with the outside through the second steam guide tube.
[0009] Furthermore, the steam transmission pipe is arranged vertically and is perpendicularly connected to the steam buffer pipe and the first heating pipe, respectively.
[0010] Furthermore, the steam transmission pipe includes a first steam transmission pipe and a second steam transmission pipe corresponding to the first steam transmission pipe, wherein the first steam transmission pipe, the second steam transmission pipe, the steam buffer pipe, and the first heating pipe are all located on the same plane.
[0011] Furthermore, the second heating tube includes a power supply end located at one end, the first steam guide tube is located on the side of the second heating tube closer to the power supply end, and the second steam guide tube is located on the side of the second heating tube away from the power supply end.
[0012] Furthermore, the water storage pipe is arranged horizontally and is perpendicularly connected to the first heating pipe.
[0013] Furthermore, the steam buffer pipe is provided with a water guide groove that extends along the length of the steam buffer pipe and communicates with the steam transmission pipe.
[0014] Furthermore, both the first heating element and the second heating element are equipped with temperature sensing probes.
[0015] This utility model also provides a high-temperature cooking oven, including a cooking oven shell and a steam generating device based on a steam buffer pipe as described above, disposed inside the cooking oven shell.
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. This utility model incorporates a steam buffer pipe between the first and second heating pipes. Water from the storage pipe enters the first heating pipe for heating. During heating, the water boils to form steam, which then enters the steam buffer pipe for storage and buffering. When the steam buffer pipe is full, the steam enters the second heating pipe for heating and is finally transmitted to the outside of the steam generator body to heat the food. The steam buffer pipe can store and stabilize the steam, making the steam entering the cooking chamber more uniform and stable. This effectively solves the problem that existing steam generators have a storage pipe and a heating pipe. Water from the storage pipe flows into the heating pipe, boils, and forms steam, which then enters the cooking chamber to heat the food. However, the steam is directly generated by the heating pipe and enters the cooking chamber, making it difficult to maintain stable steam pressure and flow rate, resulting in uneven temperature distribution within the cooking chamber and affecting the cooking effect and taste of the food.
[0018] 2. During the process of storing steam in the steam buffer tube, a small amount of steam will form condensate due to heat loss and temperature drop. The condensate will drip into the water guide tank under the action of gravity, and under the action of the steam transmission pipe, the condensate will fall back to the first heating tube, which helps to save resources.
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0028] like Figures 1 to 7 The steam generator shown includes a steam generator body 1, which includes a water storage pipe 2 for providing a water source, a first heating pipe 3 connected to the water storage pipe 2 for heating water to generate steam, a second heating pipe 4 connected to the outside, and a steam buffer pipe 5 located between the first heating pipe 3 and the second heating pipe 4 for storing and stabilizing steam. The steam generated by the first heating pipe 3 enters the steam buffer pipe 5 for storage and buffering, and then enters the second heating pipe 4 for heating and is transmitted to the outside through the second heating pipe 4 to heat food.
[0029] This invention incorporates a steam buffer pipe between the first and second heating pipes. Water from the storage pipe enters the first heating pipe for heating. During heating, the water boils and forms steam. The steam enters the steam buffer pipe for stagnation and buffering. When the steam buffer pipe is full, the steam enters the second heating pipe for heating and is finally transmitted to the outside of the steam generator to heat the food. The steam buffer pipe can store and stabilize the steam, making the steam entering the cooking chamber more uniform and stable. This effectively solves the problem in existing steam generators where water from the storage pipe flows into the heating pipe, boils, and forms steam before entering the cooking chamber to heat the food. However, the steam is directly generated by the heating pipe and enters the cooking chamber, making it difficult to maintain stable steam pressure and flow rate, resulting in uneven temperature distribution within the cooking chamber and affecting the cooking effect and taste of the food.
[0030] Furthermore, by setting a second heating tube 4, the steam entering the second heating tube 4 through the steam buffer tube 5 can be reheated, further ensuring the stability of the steam temperature and preventing the steam from condensing or losing heat during the storage of steam in the steam buffer tube 5, which would lead to the temperature not meeting the standard, thus helping to ensure the steaming effect of the food.
[0031] Optionally, in some embodiments, the first heating tube 3 is a stainless steel heating tube.
[0032] Optionally, in some embodiments, the first heating tube 3 is a titanium heating tube.
[0033] Preferably, the second heating tube 4 is a dry-burning tube, which can directly heat the steam delivered from the steam buffer tube 5 so that the steam temperature can rise rapidly; secondly, by setting the dry-burning tube, the steam temperature can be raised to 800°-1000°, preferably, the temperature is controlled at about 850°, which ensures that the steam gets enough heat and helps to extend the service life of the equipment.
[0034] Furthermore, steam enters the second heating tube 4 through the steam buffer tube 5. Under the action of the second heating tube 4, the steam temperature rises rapidly to form high-temperature steam. High-temperature steam can quickly penetrate the surface of food, allowing the food to reach the ideal cooking temperature in a short time. Due to the high heat transfer efficiency of high-temperature steam, the cooking process can be completed in a shorter time, thereby reducing the exposure time of food in a high-temperature environment, maximizing the preservation of the food's nutrients and fresh taste, and achieving the effect of locking in freshness.
[0035] Furthermore, the second heating tube 4 is a dry-burning tube. Under the secondary heating effect of the second heating tube 4, the steam forms high-temperature steam of 850°C. Even in the low-pressure environment of the plateau, it can still ensure that the steam temperature is far above the boiling point, so as to achieve the effect of quickly penetrating the food and cooking efficiently, and avoid the situation where the food is not cooked well due to the low boiling point at high altitude.
[0036] Furthermore, the steam generator body 1 includes a mounting shell for installing the water storage pipe 2, the first heating pipe 3, the second heating pipe 4, and the steam buffer pipe 5. The mounting shell is lined with a heat insulation material, which is ceramic fiber. Ceramic fiber has excellent heat insulation properties, and its low thermal conductivity can effectively prevent the heat generated by the second heating pipe 4 from being conducted to the mounting shell and other components. The second heating pipe 4 generates a large amount of heat when it is working. Without the heat insulation material, the heat would be rapidly transferred to the mounting shell or other components, causing the temperature of the mounting shell and other components to rise sharply. The ceramic fiber heat insulation layer acts as a barrier, which can reduce the rate and amount of heat transfer, so that the mounting shell and other components will not overheat due to the high temperature of the second heating pipe 4, thereby protecting the structure and performance of the mounting shell and other components and avoiding deformation or damage caused by high temperature. Finally, the ceramic fiber can effectively block the heat from the second heating pipe 4 to the outside of the mounting shell, which helps to reduce heat loss and effectively improve the overall thermal efficiency.
[0037] like Figures 1 to 7 The steam buffer pipe 5 shown is arranged in a horizontal direction, the first heating pipe 3 is located below the steam buffer pipe 5 and is arranged parallel to the steam buffer pipe 5, and a steam transmission pipe 6 is provided between the steam buffer pipe 5 and the first heating pipe 3.
[0038] Furthermore, since steam is less dense than water, hot steam has a natural tendency to move upward. The first heating pipe 3 is located below the steam buffer pipe 5, and the steam generated by the first heating pipe 3 will naturally flow upward and enter the steam buffer pipe 5 through the steam transmission pipe 6. This setting conforms to the physical characteristics of steam and does not require additional power equipment to drive the steam to flow from the first heating pipe 3 to the steam buffer pipe 5, which helps to reduce the energy consumption and complexity of the device.
[0039] Furthermore, the horizontally arranged steam buffer pipe 5 is connected to the first heating pipe 3 below it via the steam transmission pipe 6, forming a more direct steam transmission path. Compared with a complex and tortuous pipe layout, this arrangement can reduce the resistance of steam during transmission, allowing steam to enter the steam buffer pipe 5 more smoothly from the first heating pipe 3, thus ensuring the efficiency of steam transmission.
[0040] Furthermore, the first heating pipe 3 and the steam buffer pipe 5 are arranged in parallel and horizontally, so that the structure of the entire steam generator body 1 is more compact. In a limited space, this layout can make more efficient use of space and facilitate the installation and placement of each pipe.
[0041] Optionally, the steam transmission pipe 6 is provided with a gas-liquid separation mechanism 9. The gas-liquid separation mechanism 9 includes a gas-liquid separation pipe 91 and gas-liquid separation filter screens 92 located on both sides of the gas-liquid separation pipe 91. The gas-liquid separation filter screens 92 are food-grade stainless steel filter screens. The steam generated by the first heating pipe 3 contains liquid water droplets. When the steam passes through the gas-liquid separation mechanism 9, the gas-liquid separation mechanism 9 can effectively intercept the moisture, so that the steam is purer and drier, avoiding the situation where wet steam causes moisture to accumulate on the surface of the food, affecting the taste of the food.
[0042] Furthermore, the gas-liquid separation filter 92 is a multi-layer corrugated folded filter. The gas-liquid separation filter 92 is composed of multiple layers of stainless steel metal mesh, each layer of mesh is corrugated and folded, thus forming a tortuous steam channel. Each layer of mesh has mesh holes, and the mesh hole diameter gradually decreases from the side closer to the first heating tube 3 to the side farther away from the first heating tube 3. For example, the outer layer is 80 mesh, the middle layer is 100 mesh, and the inner layer is 120 mesh on the side closer to the first heating tube 3. When the water droplets carried by the steam pass through the corrugated channel, they are captured by the mesh wall due to inertial collision and adsorption, and the water droplets flow back to the first heating tube 3.
[0043] Furthermore, the gas-liquid separation pipe 91 is equipped with a filter filler, which is a food-grade stainless steel wire mesh. The filter filler can effectively intercept tiny droplets and impurities in the steam, further improving the gas-liquid separation effect. The gas-liquid separation filter 92, the stainless steel wire mesh, and the gas-liquid separation filter 92 together form a three-stage gas-liquid separation system, which is conducive to achieving a better gas-liquid separation effect and ensuring that the steam entering the steam buffer pipe 5 is pure and dry.
[0044] like Figures 1 to 7 The second heating tube 4 shown is located below the steam buffer tube 5 and is arranged parallel to the steam buffer tube 5. The second heating tube 4 is provided with a first steam guide tube 71 and a second steam guide tube 72. The second heating tube 4 is connected to the steam buffer tube 5 through the first steam guide tube 71 and is connected to the outside through the second steam guide tube 72.
[0045] Furthermore, the second heating tube 4 is connected to the steam buffer tube 5 through the first steam guide tube 71. The steam buffer tube 5 can buffer and stabilize the steam generated and transmitted from the first heating tube 3, so that the steam pressure and flow rate entering the second heating tube 4 are continuous and stable, avoiding uneven heating caused by steam pressure fluctuations, and providing the second heating tube 4 with continuous and stable steam to ensure the normal operation of the device.
[0046] Specifically, the second heating pipe 4 is connected to the cooking chamber through the second steam guide pipe 72, and the cooking chamber is located outside the steam generator body 1.
[0047] Furthermore, the parallel arrangement of the second heating pipe 4 and the steam buffer pipe 5 helps the steam to be evenly distributed in the second heating pipe 4, making the steam heating more uniform. The arrangement of the first steam guide pipe 71 and the second steam guide pipe 72 can also optimize the flow path of the steam in the second heating pipe 4, reduce the dead zone of steam heating, and help improve the heating quality of the steam.
[0048] Furthermore, the second heating tube 4 is arranged in parallel with the steam buffer tube 5. This compact layout helps to reduce the overall volume of the steam generator body 1, so that the steam generator body 1 can save more space.
[0049] like Figures 1 to 7 The steam transmission pipe 6 shown is arranged vertically and is perpendicularly connected to the steam buffer pipe 5 and the first heating pipe 3 respectively;
[0050] Furthermore, the vertical connection allows for a smoother change in the flow direction of steam as it flows from the first heating pipe 3 to the steam buffer pipe 5, reducing resistance to steam flow. Compared to the sharp turns or complex bends that may occur with non-vertical connections, vertical connections can reduce energy loss, ensure smoother steam transmission, and improve the efficiency of steam transmission.
[0051] Furthermore, the vertical connection structure allows for a more compact layout of the steam generator body 1, which helps save installation space. Within a limited space, the vertical steam transmission pipe 6 can effectively connect the first heating pipe 3 and the steam buffer pipe 5, avoiding excessively long or complex pipe arrangements. This makes the steam generator body 1 more regular in structure, facilitating installation and maintenance.
[0052] Furthermore, the vertically arranged steam transmission pipe 6 can utilize gravity to allow the liquid droplets in the steam to settle naturally. When steam enters the steam transmission pipe 6 from the first heating pipe 3, the heavier liquid droplets will settle downwards under the action of gravity, thereby separating from the steam, which helps to improve the efficiency of gas-liquid separation.
[0053] like Figures 1 to 7 The steam transmission pipe 6 shown includes a first steam transmission pipe 61 and a second steam transmission pipe 62 corresponding to the first steam transmission pipe 61. The first steam transmission pipe 61, the second steam transmission pipe 62, the steam buffer pipe 5, and the first heating pipe 3 are all located on the same plane.
[0054] Furthermore, the arrangement of the first steam transmission pipe 61 and the second steam transmission pipe 62 is equivalent to widening the steam transmission channel. When the first heating pipe 3 generates a large amount of steam, a single steam transmission pipe 6 may not be able to meet the demand for rapid steam transmission. However, with the arrangement of the first steam transmission pipe 61 and the second steam transmission pipe 62, steam can be transmitted through the two pipes simultaneously, which greatly increases the overall steam flow rate and allows more steam to be transmitted from the first heating pipe 3 to the steam buffer pipe 5 at the same time, thus helping to improve the steam transmission efficiency.
[0055] Furthermore, if there is only one steam transmission pipe, the steam transmission will be severely affected if the pipe fails. However, by setting up a first steam transmission pipe 61 and a second steam transmission pipe 62, when one pipe has a problem, the other pipe can still continue to transmit steam, maintain the basic operation of the device, reduce the impact of pipe failure on the steam transmission efficiency, and improve the reliability of the device.
[0056] Furthermore, by placing the first steam transmission pipe 61, the second steam transmission pipe 62, the steam buffer pipe 5, and the first heating pipe 3 on the same plane, space can be utilized more effectively, space waste can be avoided, and the space occupied by the steam generator body 1 can be reduced.
[0057] like Figures 1 to 7 The second heating tube 4 shown includes a power supply terminal 41 at one end, the first steam guide tube 71 is located on the side of the second heating tube 4 close to the power supply terminal 41, and the second steam guide tube 72 is located on the side of the second heating tube 4 away from the power supply terminal 41.
[0058] Furthermore, after the steam enters the second heating tube 4 from the first steam guide pipe 71, since the second steam guide pipe 72 is at the other end, the steam will flow along the second heating tube 4 from the side closer to the power supply end 41 to the side farther away from the power supply end 41, forming a relatively smooth steam flow path. This unidirectional flow helps the steam to fully contact the second heating tube 4, which is beneficial to improving the heat exchange efficiency, so that the steam can better absorb heat, and helps to improve the quality and temperature of the steam.
[0059] Optionally, the temperature of the second heating tube 4 located near the power supply terminal 41 is relatively low, and the temperature of the second heating tube 4 located away from the power supply terminal 41 is relatively high. When steam enters the relatively low-temperature area of the second heating tube 4 from the first steam guide tube 71, there will be no rapid heat exchange due to excessive temperature difference, which will cause the steam state to become unstable. As the steam flows towards the high-temperature area, the steam can gradually absorb heat, achieving a stable and efficient heating process, which helps to improve the quality and stability of the steam.
[0060] like Figures 1 to 7 The water storage pipe 2 shown is arranged horizontally and is perpendicularly connected to the first heating pipe 3;
[0061] Furthermore, the connection method between the water storage pipe 2 and the first heating pipe 3 helps the water to enter the first heating pipe 3 more evenly. When the water flows from the water storage pipe 2 into the first heating pipe 3 which is vertically connected to the water storage pipe 2, the water flow can be distributed more evenly on the cross-section of the first heating pipe 3, avoiding the situation where the water flow is concentrated on one side of the first heating pipe 3, so that the water in the entire first heating pipe 3 can fully participate in the heating process.
[0062] Furthermore, the horizontally arranged water storage pipe 2 and the vertically connected first heating pipe 3 enable the layout of the entire steam generator body 1 to be more compact, which helps to reduce the space occupied by the device.
[0063] Specifically, the water storage pipe 2 is equipped with a liquid level sensor, a solenoid valve, and a water pump. The liquid level sensor is electrically connected to the main control board. When the liquid level sensor detects that the water level in the water storage pipe 2 is too low, the liquid level sensor transmits a signal to the main control board. The main control board controls the water pump and the solenoid valve to open so that external water can enter the water storage pipe 2. When the liquid level sensor detects that the water level in the water storage pipe 2 exceeds the preset value, the liquid level sensor continues to send a signal to the main control board, and the main control board closes the solenoid valve and the water pump.
[0064] like Figures 1 to 7 The steam buffer pipe 5 shown is provided with a water guide trough 51 extending along the length of the steam buffer pipe 5 and communicating with the steam transmission pipe 6.
[0065] Furthermore, during the process of storing steam in the steam buffer pipe 5, a small amount of steam forms condensate due to heat loss and temperature drop. This condensate is collected through the water guide trough 51 and falls back to the first heating pipe 3 through the steam transmission pipe 6, so that the condensate can be reused, reducing the waste of water resources and also reducing the dependence on external water sources during the operation of the device.
[0066] Furthermore, the recycling of condensate not only saves water resources but also reduces the heat loss caused by condensate discharge. By reintroducing the condensate into the first heating tube 3, its residual heat can be utilized, further improving the energy efficiency of the entire device.
[0067] like Figures 1 to 7 The first heating tube 3 and the second heating tube 4 shown are both equipped with temperature sensing probes 11;
[0068] Furthermore, the temperature sensor 11 can monitor the temperature changes in the first heating tube 3 and the second heating tube 4 in real time and transmit the temperature signal to the main control board, so that the device can accurately control the heating power according to the actual temperature and ensure the temperature of the steam is stable. Secondly, through accurate temperature monitoring, overheating or underheating can be avoided, thereby improving the heating efficiency of the entire device.
[0069] Furthermore, the real-time monitoring function of the temperature sensor 11 can ensure that the steam maintains a stable temperature during the heating process, avoiding a decrease in steam quality due to temperature fluctuations. This is especially important for cooking processes that require high-quality steam, and can significantly improve the cooking effect and the taste of food. Secondly, by precisely controlling the heating temperature, the condensation water formed during the steam transmission process due to temperature drop can be reduced, thereby improving the dryness and purity of the steam.
[0070] Furthermore, the temperature sensor 11 can monitor the temperature inside the first heating tube 3 and the second heating tube 4 in real time. When the temperature exceeds the set safety threshold, the main control board can automatically cut off the heating power supply to prevent the device from being damaged due to high temperature.
[0071] like Figures 1 to 7 The high-temperature cooking oven shown includes a cooking oven shell 8 and a steam generating device based on a steam buffer tube as described above, disposed within the cooking oven shell 8.
[0072] Furthermore, the cooking chamber shell 8 is provided with a cooking chamber that communicates with the second heating pipe 4. The steam generating device body 1 can continuously and stably generate steam to supply to the cooking chamber. The steam buffer pipe 5 is set to make the steam generation and transmission process more stable and uniform, and there will be no sudden interruption or violent fluctuation of steam supply, which ensures the continuity of the cooking process and is conducive to improving the cooking effect and the stability of the device quality.
[0073] The implementation method of this embodiment is as follows:
[0074] A steam generating device based on a steam buffer pipe includes a steam generating device body 1. The steam generating device body 1 includes a water storage pipe 2 for providing a water source, a first heating pipe 3 connected to the water storage pipe 2 for heating water to generate steam, a second heating pipe 4 connected to the outside, and a steam buffer pipe 5 located between the first heating pipe 3 and the second heating pipe 4 for storing and stabilizing steam. Water in the water storage pipe 2 enters the first heating pipe 3 for heating. During the heating process, the water boils to form steam. The steam enters the steam buffer pipe 5 for residence and buffering. When the steam buffer pipe 5 is full of steam, the steam enters the second heating pipe 4 from the steam buffer pipe 5 for heating. Finally, the steam is transmitted to the outside of the steam generating device body 1 through the second heating pipe 4 for heating food. The steam buffer pipe 5 can store and stabilize steam, so that the steam entering the steaming chamber is more uniform and stable.
[0075] A steam buffer pipe 5 is arranged horizontally, and a first heating pipe 3 is located below and parallel to the steam buffer pipe 5. A steam transmission pipe 6 is provided between the steam buffer pipe 5 and the first heating pipe 3. The steam transmission pipe 6 includes a first steam transmission pipe 61 and a second steam transmission pipe 62. Both the first steam transmission pipe 61 and the second steam transmission pipe 62 are arranged vertically and are perpendicularly connected to the steam buffer pipe 5 and the first heating pipe 3, respectively. A water guide trough 51 is provided inside the steam buffer pipe 5, extending along the length of the steam buffer pipe 5. The water guide trough 51 is connected to the first steam transmission pipe 61 and the second steam transmission pipe 62, respectively. During the process of storing steam in the steam buffer pipe 5, a small amount of steam forms condensate due to heat loss and temperature drop. This condensate is collected through the water guide trough 51 and falls back to the first heating pipe 3 through the first steam transmission pipe 61 and the second steam transmission pipe 62, so that the condensate can be reused, reducing water waste and reducing the dependence on external water sources during the operation of the device.
[0076] The second heating tube 4 includes a power supply end 41 at one end, a first steam guide tube 71 located on the side of the second heating tube 4 closer to the power supply end 41, and a second steam guide tube 72 located on the side of the second heating tube 4 away from the power supply end 41. After steam enters the second heating tube 4 from the first steam guide tube 71, since the second steam guide tube 72 is at the other end, the steam will flow along the second heating tube 4 from the side closer to the power supply end 41 to the side away from the power supply end 41, forming a relatively smooth steam flow path. This unidirectional flow helps the steam to fully contact the second heating tube 4, which is beneficial to improving the heat exchange efficiency, so that the steam can better absorb heat, and helps to improve the quality and temperature of the steam.
[0077] A high-temperature cooking oven includes a cooking oven shell 8 and a steam generating device based on a steam buffer pipe as described above, disposed within the cooking oven shell 8. The cooking oven shell 8 has a cooking chamber communicating with a second heating pipe 4. The steam generating device body 1 can continuously and stably generate steam to supply to the cooking chamber. The steam buffer pipe 5 is designed to make the steam generation and transmission process more stable and uniform, preventing sudden interruptions or violent fluctuations in steam supply, ensuring the continuity of the cooking process, and improving the stability of the cooking effect and device quality.
[0078] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
