[0002] A steaming drum is a device used for steaming food (such as boiling noodles or steaming buns). The bottom of the steaming drum is heated by a stove. Currently, most steaming drums only heat a single flat surface at the bottom, resulting in low heating efficiency. This means the stove flame can only heat the bottom of the drum, and the combustion flame and flue gas are not fully utilized, leading to inefficient heat transfer. Furthermore, the existing steaming drums have a relatively simple structure, which limits their heat exchange efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a high-efficiency heat exchange cooking cylinder. The double-layer cylinder is recessed inward to form a combustion heat exchange cavity, allowing the burner to be placed in the combustion heat exchange cavity for combustion operation, effectively utilizing the thermal energy of the combustion flame. The combustion heat exchange cavity collects high-temperature flue gas, which then undergoes heat exchange through the heat exchange flue pipe placed inside the double-layer cylinder, effectively utilizing the thermal energy of the flue gas.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the embodiments:

[0029] Example

[0030] like Figures 1-6 As shown, a high-efficiency heat exchange cooking cylinder includes a combustion stove 5, a double-layer cylinder 1, a combustion heat exchange chamber 6, and a heat exchange flue 7. The bottom of the double-layer cylinder 1 is sealed with a bottom plate. The combustion heat exchange chamber 6 protrudes from the bottom plate of the double-layer cylinder 1, and the bottom plate of the double-layer cylinder 1 is recessed towards the inside of the double-layer cylinder 1 to form the combustion heat exchange chamber 6 (viewed from inside the double-layer cylinder 1, the combustion heat exchange chamber 6 protrudes from the bottom plate of the double-layer cylinder 1, and the combustion heat exchange chamber 6 is in the shape of an inverted barrel). In this invention, the combustion heat exchange chamber 6 is integrally formed with the inner layer of the double-layer cylinder 1, and a protruding combustion heat exchange chamber 6 is formed in the center of the inside of the double-layer cylinder 1, which increases the heat exchange area and allows the water inside the double-layer cylinder 1 to be fully heated; Figure 2 As shown, the combustion heat exchange chamber 6 is located at the center of the double-layer cylinder 1. The burner 5 is installed in the combustion heat exchange chamber 6. When the burner 5 is ignited, its flame is placed inside the combustion heat exchange chamber 6, heating both the combustion heat exchange chamber 6 and the water inside the double-layer cylinder 1. At least three support legs 4 are connected to the bottom of the double-layer cylinder 1.

[0031] The top of the burner 5 is connected and fixed to the bottom plate of the double-layer cylinder 1 by bolts; preferably, a burner mounting plate is welded and fixed to the bottom plate of the double-layer cylinder 1, and the top of the burner 5 is detachably installed on the burner mounting plate by bolts. The side wall of the double-layer cylinder 1 is provided with a burner switch 51 corresponding to the burner 5. The burner switch 51 is used for one-button operation of ignition and fuel filling. In this embodiment, taking a gas stove as an example, when the burner switch 51 is turned on, the burner 5 continuously supplies gas and ignites and burns.

[0032] like Figure 2 , Figure 6 As shown, the combustion heat exchange chamber 6 is externally connected to a heat exchange flue 7 (the high-temperature flue gas from the combustion stove 5 is collected in the combustion heat exchange chamber 6 and transported to the heat exchange flue 7). The heat exchange flue 7 is coiled around the combustion heat exchange chamber 6 (the heat exchange flue 7 of this utility model is preferably a metal corrugated coil, and the high-temperature flue gas in the heat exchange flue 7 exchanges heat with the water inside the double-layer cylinder 1, making full use of the heat energy of the high-temperature flue gas, while allowing the water inside the double-layer cylinder 1 to be heated more fully). The outlet end 72 of the heat exchange flue 7 is sealed through the bottom plate of the double-layer cylinder 1 or sealed through the cylinder wall of the double-layer cylinder 1.

[0033] In some embodiments, the inlet end 71 of the heat exchange flue 7 is in sealed communication with the combustion heat exchange chamber 6 via a flange. A flue gas connector is provided through the bottom plate of the double-layer cylinder 1, and the outlet end 72 of the heat exchange flue 7 is sealed to the flue gas connector via a flange. The flue gas connector is sealed to an exhaust pipe, through which exhaust operations are performed.

[0034] The preferred double-layer cylinder 1 of this utility model consists of an inner cylinder 2, an outer cylinder 3, and an insulation layer disposed between the inner cylinder 2 and the outer cylinder 3. The insulation layer plays a role in heat insulation and heat preservation, preventing heat loss.

[0035] In some embodiments, the bottom of the inner cylinder 2 is a cylinder bottom plate 21 (the double-layer cylinder 1 only has a double-layer structure in its cylinder wall, and the cylinder bottom plate 21 is the cylinder bottom plate of the double-layer cylinder 1), such as Figure 7 As shown, the combustion heat exchange chamber 6 is located at the top of the bottom plate 21 of the cylinder. The combustion heat exchange chamber 6 forms a recessed structure within the inner cylinder 2 (preferably, the combustion heat exchange chamber 6 is integrally formed on the bottom plate 21 of the cylinder, and the combustion heat exchange chamber 6 serves as a stretching member for the inward recess of the bottom plate 21 of the cylinder). The flame and heat in the combustion heat exchange chamber 6 can fully exchange heat with the water in the inner cylinder 2 (increasing the heat exchange area). The bottom plate 21 of the inner cylinder 2 is connected to a drain pipe 8, which is used to discharge the water stored in the inner cylinder 2 (the water inside the double-layer cylinder 1 is actually located in the cavity of the inner cylinder 2).

[0036] like Figure 2 , Figure 5As shown, the inner wall of the inner cylinder 2 has an annular support step 22. A steaming rack with mesh is placed on the annular support step 22. When steaming buns using the high-efficiency heat exchange steaming cylinder of this utility model, a steaming rack with mesh is placed on the annular support step 22, and buns or steamers are placed on the steaming rack. The water in the inner cylinder 2 below the steaming rack is heated to generate high-temperature steam and steam the buns. When cooking noodles using the high-efficiency heat exchange steaming cylinder of this utility model, a steaming rack with mesh is placed on the annular support step 22. The mesh of the steaming rack is fine, and the noodles are placed on the steaming rack. At this time, the water inside the steaming cylinder is higher than the steaming rack by a certain height. The steaming cylinder is at least two-thirds full of water. The water in the inner cylinder 2 boils and cooks the noodles. The two ends of the heat exchange flue 7 (inlet end 71 and outlet end 72) are connected by flanges for detachability. After draining the water through the drain pipe 8, the heat exchange flue 7 can be removed for cleaning.

[0037] In use, the burner 5 is installed below the bottom plate 21 of the cylinder, so that the combustion area of ​​the burner 5 is located in the combustion heat exchange chamber 6. The burner 5 is ignited and combustion begins. The combustion flame heats the water inside the inner cylinder 2 through the combustion heat exchange chamber 6 and the bottom plate 21. The raised combustion heat exchange chamber 6 inside the inner cylinder 2 increases the heating area (see...). Figure 7 This also ensures that the water in the inner cylinder 2 is heated evenly, improving the heating efficiency of the water inside the inner cylinder 2. The high-temperature flue gas generated by combustion is transported to the heat exchange flue 7, which is coiled inside the inner cylinder 2. This allows for thorough heat exchange between the high-temperature flue gas and the water inside the inner cylinder 2, effectively utilizing the flue gas's thermal energy and improving heat exchange efficiency. The combustion stove 5 of this invention can be equipped with a fan. The fan provides the air required for combustion and also blows out airflow to guide the high-temperature flue gas sequentially through the inner cavity of the combustion heat exchange chamber 6, the heat exchange flue 7, and the exhaust pipe for flue gas utilization and emission.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
