[0002] Steam heating is a method of indirectly heating an object by generating steam from heated water. Currently, in the process of using steam heating, the generated steam is usually directly discharged into the outside air. Since steam contains a large amount of heat, direct discharge easily leads to heat loss. Moreover, because the temperature of the outside air is low, the steam will condense into water droplets. The water supply in the steam chamber is actually constantly decreasing, requiring staff to continuously replenish the water in the steam chamber. This results in a waste of water resources and a large amount of heat energy in the steam, causing serious waste of heat energy and water resources, and making it uneconomical to use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] In this embodiment of the invention, to address the problem in the prior art where steam is directly discharged into the outside air, causing it to condense into water droplets upon cooling, and the water supply in the steam chamber continuously decreasing, requiring constant replenishment by staff, resulting in water and steam energy waste and poor economic efficiency, the invention recovers and reuses the discharged steam. The steam's heat energy is used to supplement the water in the steam chamber, and the condensed water flows back into the chamber, reducing waste of water and heat energy and improving economic efficiency. The following is a detailed description of this embodiment of the invention:

[0035] like Figures 1-9The steam heating structure shown includes a steam box 1, a box cover 2 at the top of the steam box 1, an annular shell 3 at the bottom of the box cover 2, the top of the annular shell 3 being tightly rotatably connected to the box cover 2, a circular plate 4 being fixedly installed on the inner circumference of the annular shell 3 near the bottom, a through hole being provided in the center of the circular plate 4, and a plurality of slots being evenly provided on the inner circumference of the annular shell 3, a tube 5 being embedded in the slots, an inlet being provided at the centrifugal end of the tube 5 and an outlet being provided at the centrifugal end of the tube 5 near the bottom.

[0036] More specifically, the bottom of the steamer 1 is provided with a heater body 6, the inside of the steamer 1 is provided with a chamber, the top of the steamer 1 is provided with a box opening, the box opening is connected to the chamber, and the box cover 2 is detachably installed at the box opening.

[0037] In the specific implementation process, the lid 2 is opened, and an appropriate amount of water is injected into the chamber of the steamer 1 through the opening. The object to be heated is placed in the chamber, and the water in the steamer 1 is heated by the heater body 6. The steam generated by heating the water in the steamer 1 heats the object to be heated and applies a rotational driving force to the annular shell 3, causing the annular shell 3 to rotate around the center of the lid 2. The steam continuously moves upward and enters the interior of the annular shell 3 through the through hole of the circular plate 4, and then enters through the inlets of multiple tubes 5 installed on the annular shell 3. Afterward, the steam is discharged from the outlet of the tubes 5 and re-enters the chamber, so that the steam forms a cycle in the chamber of the steamer 1, the annular shell 3, and the tubes 5. A portion of the steam entering the annular shell 3 will be converted into steam. Water droplets condense on the inner wall of the annular shell 3 and the top wall of the circular plate 4. The rotation of the annular shell 3 and the circular plate 4 causes the water droplets inside the annular shell 3 to be rapidly thrown onto the inner circumference of the annular shell 3 under the centrifugal force. As the annular shell 3 continues to rotate, water droplets continuously flow from the inlet of the pipe body 5 into the pipe body 5 and exit from the outlet of the pipe body 5 into the steam chamber 1. Through the action of the annular shell 3 and the pipe body 5, both the generated steam and water droplets can flow back into the steam chamber 1. The discharged steam is recovered and reused, and the heat energy in the steam is used to auxiliary heat the water in the steam chamber 1. The condensed water then flows back into the steam chamber 1, reducing waste of water resources and heat energy and improving economic efficiency.

[0038] Based on the above embodiment, a support column 7 is fixedly installed on the bottom wall of the steam oven 1, and a tray 8 is fixedly installed on the top of the support column 7. Multiple drainage holes are evenly arranged on the tray 8.

[0039] In the specific implementation process, the lid 2 is opened and the object to be heated is placed on the tray 8. The water in the steamer 1 is heated and evaporated. The steam passes through multiple holes on the tray 8, which can more evenly heat the object to be heated, resulting in good heating effect. In addition, the tray 8 provides stable support for the object to be heated, improving work efficiency.

[0040] Based on the above embodiment, a cylindrical body 9 is concentrically fixed at the bottom end of the box cover 2. The bottom end of the cylindrical body 9 passes through a through hole. The outer circumferential wall of the cylindrical body 9 is tightly rotatably connected to the inner circumferential wall of the through hole. An air inlet is provided at the bottom end of the cylindrical body 9. A rubber check valve 10 is embedded at the air inlet. An air outlet is provided on the outer circumferential wall of the cylindrical body 9. Multiple force plates 11 are uniformly fixed on the inner circumferential wall of the annular shell 3. The force plates 11 are in an inclined state. The end of the force plate 11 away from the inner circumferential wall of the annular shell 3 is tangent to the outer circumferential wall of the cylindrical body 9. The end of the force plate 11 away from the inner circumferential wall of the annular shell 3 is in tight sliding contact with the outer circumferential wall of the cylindrical body 9. The top end of the force plate 11 is in tight sliding contact with the bottom end of the box cover 2. The bottom end of the force plate 11 is in tight contact with the top end of the circular plate 4.

[0041] More specifically, when the rubber check valve 10 is in its initial state, its input end has the same shape as the air inlet and is in the open state, and its output end is in the closed state. When steam flows in from the input end of the rubber check valve 10 and is discharged from the output end of the rubber check valve 10, the output end of the rubber check valve 10 changes from the closed state to the open state due to the action of the steam. The size of the air outlet of the cylinder 9 is much smaller than the size of the input end of the rubber check valve 10.

[0042] In the specific implementation process, steam enters the interior of the cylinder 9 through the rubber check valve 10 and exits from the outlet of the cylinder 9. Since the outlet of the cylinder 9 is much smaller than the input end of the rubber check valve 10, the steam exits from the outlet of the cylinder 9 at a relatively high speed. The steam that is rapidly blown out from the outlet of the cylinder 9 directly acts on the inclined force plate 11. Due to the inclined position of the force plate 11, the steam pushes the force plate 11 to rotate. Through the force plate 11, the annular shell 3 and the circular plate 4 rotate about the axis of the cylinder 9. As steam flows through the cylinder 9, the acceleration effect achieved by the air inlet and outlet of the cylinder 9 increases the kinetic energy of the steam. This allows the steam to drive the annular shell 3 and the circular plate 4 using its own kinetic energy, eliminating the need for external driving force and resulting in low energy consumption. Furthermore, the rotation of the annular shell 3 causes water droplets generated by the condensation of steam within the annular shell 3 to be thrown onto the inner circumference of the annular shell 3. The water droplets are then guided back into the steam chamber 1 through the pipe 5, reducing the waste of water resources and heat energy and improving the economic efficiency of use.

[0043] Based on the above embodiment, it also includes a fixing ring 12, an annular groove 13 is provided on the bottom wall of the steamer 1, a plurality of guide posts 14 are evenly provided at the bottom end of the fixing ring 12, the bottom end of the guide posts 14 slides into the annular groove 13, a plurality of mounting posts 15 are evenly provided at the top end of the fixing ring 12, the number of mounting posts 15 is the same as the number of tubes 5, the top end of the mounting posts 15 is detachably connected to the bottom end of the tubes 5, a plurality of brackets 16 are evenly provided at the top end of the fixing ring 12, and a rotating shaft 17 is rotatably provided on the brackets 16;

[0044] It also includes multiple stirring plates 18, which are rotatably mounted on the support 16 via a rotating shaft 17. A bending spring 19 is fixedly provided between the bottom end of the stirring plate 18 and the centrifugal end of the support 16, and a linkage rod 20 is fixedly provided at the centrifugal end of the stirring plate 18.

[0045] A circular wave track 21 is fixedly installed on the inner circumference of the steam oven 1 near the bottom.

[0046] The bottom end of the linkage 20 contacts the upper surface of the annular wave track 21;

[0047] More specifically, as the name suggests, the annular wave track 21 is an annular structure and is wave-shaped. Therefore, the annular wave track 21 has multiple highest points and multiple lowest points. When the bending spring 19 is in the initial state, the linkage rod 20 slides in contact with the lowest point on the upper surface of the annular wave track 21.

[0048] In the specific implementation process, during the rotation of the annular shell 3, the fixed ring 12 is driven to rotate by multiple tubes 5 and multiple mounting columns 15. Multiple guide columns 14 slide in the annular groove 13, and the rotation of the fixed ring 12 is supported by the multiple guide columns 14. The fixed ring 12 drives the stirring plate 18 to rotate around the center of the fixed ring 12. Since the annular wave track 21 provides forced guidance to the linkage rod 20, and since the linkage rod 20 is fixedly connected to the stirring plate 18, it is guided by the annular wave track 21. During the rotation of the linkage rod 20 and the stirring plate 18 around the center of the fixed ring 12, the linkage rod 20 and the stirring plate 18 rotate around the rotating shaft 17. The stirring plate 18 swings up and down continuously during the revolution. Through the revolution and swing of the stirring plate 18, the water in the steamer 1 is stirred and turbulent, so that the water in the steamer 1 is heated evenly and the heating efficiency of the water is high.

[0049] Based on the above embodiment, a first connecting seat 22 is fixedly provided at the bottom end of the pipe body 5. A cross-shaped locking plate 23 is provided at the end of the first connecting seat 22 facing away from the pipe body 5. A second connecting seat 24 is fixedly provided at the top end of the mounting column 15. A cross-shaped locking groove 25 is provided at the end of the second connecting seat 24 facing away from the mounting column 15. The bottom end of the cross-shaped locking plate 23 extends into the cross-shaped locking groove 25. An annular rubber ring 26 is fixedly provided at the bottom end of the first connecting seat 22. The end of the annular rubber ring 26 facing away from the first connecting seat 22 is pressed and contacted with the top end of the second connecting seat 24.

[0050] In the specific implementation process, when installing the lid 2 on the steamer 1, first place the lid 2 upright above the steamer 1, and then move the lid 2 downward so that multiple tubes 5 first extend into the steamer 1 until the bottom end of the cross-shaped locking plate 23 on the first connecting seat 22 extends into the cross-shaped locking groove 25. The annular rubber ring 26 plays a shock-absorbing and buffering role between the first connecting seat 22 and the second connecting seat 24. Through the locking structure of the cross-shaped locking plate 23 and the cross-shaped locking groove 25, the detachable connection between the tube 5 and the mounting column 15 is realized, improving the convenience of installation and disassembly.

[0051] Based on the above embodiment, a guide plate 27 is fixedly installed inside the tube body 5 in an inclined state, and the outlet on the tube body 5 is also in an inclined state. The inclination angle of the guide plate 27 is the same as the inclination angle of the outlet of the tube body 5, and the upper surface of the guide plate 27 is flush with the inner bottom wall of the outlet of the tube body 5.

[0052] In the specific implementation process, the water droplets and steam flowing into the inside of the pipe body 5 through the inlet of the pipe body 5 are guided by the guide plate 27 and then discharged from the outlet of the pipe body 5. Because the outlet of the pipe body 5 is inclined, the water droplets can fall more smoothly into the chamber of the steam box 1. Since the steam discharged from the outlet of the pipe body 5 has downward potential energy, the steam is refracted after contacting the inner wall of the steam box 1, which plays a role in the flow around the steam that has just been heated and evaporated, increasing the residence time of the steam in the chamber of the steam box 1 and further improving the heating effect.

[0053] Based on the above embodiment, an explosion-proof pressure relief valve 28 is connected to the front end of the steamer 1 near the top, and a drain pipe 29 is connected to the front end of the steamer 1 near the bottom. A baffle 30 is detachably installed at the output end of the drain pipe 29, and a pull ring 31 is installed on the baffle 30.

[0054] In the specific implementation process, when the pressure inside the steamer 1 is too high, the pressure inside the steamer 1 is automatically released by the explosion-proof pressure relief valve 28 to maintain the stable air pressure inside the steamer 1. The explosion-proof pressure relief valve 28 is a product available on the market. Any product that can achieve the function in this application can be used. By opening the baffle 30 through the pull ring 31, the residual water inside the steamer 1 can be discharged through the drain pipe 29, improving the convenience of use.

[0055] Based on the above embodiment, a first magnetic block 32 is fixedly installed on both sides of the outer wall of the steam oven 1 near the top, and a second magnetic block 33 is fixedly installed on both sides of the outer wall of the lid 2, and the first magnetic block 32 and the second magnetic block 33 have opposite magnetic properties.

[0056] In the specific implementation process, when the lid 2 is installed on the top of the steamer 1, the first magnetic block 32 and the second magnetic block 33 are mutually attracted. The first magnetic block 32 and the second magnetic block 33 can play a role in aligning the lid 2 when it is installed on the top of the steamer 1, thereby improving the reliability of use.

[0057] Based on the above embodiment, an observation hole is provided on the side wall of the steamer 1, and a transparent plate 34 is provided at the observation hole;

[0058] In practice, the transparent panel 34 facilitates observation of the conditions inside the steam oven 1, improving ease of use.

[0059] Based on the above embodiment, the top of the box cover 2 is provided with two handles 35, which are symmetrically distributed;

[0060] In practice, two handles 35 facilitate the opening and closing of the lid 2, improving ease of use.

[0061] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
