It can effectively improve the energy efficiency of energy-saving stoves, reduce cooking costs, and improve kitchen work efficiency. It has the dual functions of environmental protection and economy, and has certain practicality.
[0004] This utility model achieves the above-mentioned objective through the following technical solution: a waste heat recycling device for an energy-saving stove, comprising an energy-saving stove, an annular plate fixedly connected to the top side of the energy-saving stove by screws, an annular cylinder fixedly connected to the inner wall of the annular plate, a storage ring fixedly connected to the top side of the annular cylinder, a burner installed in the middle of the top side of the energy-saving stove, an arc ring frame fixedly connected to the outer wall of the bottom end of the burner, the outer diameter of the arc ring frame being the same as the inner diameter of the annular cylinder, a circulation box fixedly connected to one side of the annular cylinder, and a water inlet pipe fixedly connected to the top side of the circulation box.
[0005] Preferably, an L-shaped conduit is fixedly connected to the top center of the circulation box, and a heating box is fixedly connected to the end of the L-shaped conduit away from the circulation box. A horizontal pipe is fixedly connected to the bottom side of the heating box.
[0006] Preferably, the end of the horizontal pipe away from the heating box is fixedly connected to a water pump through the energy-saving stove, and the top of the water pump is fixedly connected to a vertical pipe, the top of the vertical pipe being connected to the interior of the energy-saving stove and the circulation box.
[0007] Preferably, the bottom inner wall of the heating box is symmetrically fixedly connected with support plates, the length of the support plates is the same as the length of the front and rear inner walls of the heating box, and the top side of the support plates is fixedly connected with U-shaped plates.
[0008] Preferably, the U-shaped plate is symmetrically and fixedly connected with baffles on both sides, and there is a gap between the baffles and the inner wall of the heating box. The length of the baffles is the same as the distance between the front and rear inner walls of the heating box.
[0009] Preferably, four sliding rails are symmetrically fixedly connected to the inner wall of the U-shaped plate.

[0012] The beneficial effects of this utility model are as follows: By setting up a water inlet pipe, users can fill the circulation tank with water through the inlet pipe. The water will flow into the irregular space formed by the energy-saving stove, the annular cylinder, and the circulation tank. When the burner is started through the regulating valve, the burner flame will not only heat the bottom of the pot, but also heat the surrounding air and the arc ring frame. The arc ring frame can effectively boil the water in the irregular space, causing a large amount of water vapor to collect at the top of the circulation tank and be transmitted through the L-shaped conduit into the U-shaped interlayer between the heating box and the U-shaped plate. The water vapor will first come into contact with the U-shaped plate and the baffle plate. After being blocked by the baffle plate, the water vapor flows clockwise along the U-shaped interlayer. When the steam comes into contact with the U-shaped plate, it heats the U-shaped plate. The U-shaped plate heats the air in the rectangular space formed by the U-shaped plate and the heating box, thus heating the food placed on the upper part of the plate. A large amount of steam eventually turns into water and slides down to the bottom of the U-shaped interlayer through the gap between the baffle and the heating box. At this time, the water pump draws the condensate from the U-shaped interlayer through the horizontal pipe and sends it back into the irregular space through the vertical pipe. After being heated and boiled again, the cycle is completed. This effectively improves the energy efficiency of the energy-saving stove, reduces cooking costs, and improves kitchen work efficiency. It has the dual functions of being environmentally friendly and economical, which has certain practicality. Attached Figure Description

An annular plate 3 is fixedly connected to the top side of the energy-saving stove 1 by screws. An annular cylinder 4 is fixedly connected to the inner wall of the annular plate 3. A storage ring 5 is fixedly connected to the top side of the annular cylinder 4. A burner 6 is installed in the middle of the top side of the energy-saving stove 1. An arc ring frame 7 is fixedly connected to the outer wall of the bottom end of the burner 6. The outer diameter of the arc ring frame 7 is the same as the inner diameter of the annular cylinder 4. A circulation box 8 is fixedly connected to one side of the annular cylinder 4. A water inlet pipe 20 is fixedly connected to the top side of the circulation box 8. The irregular space formed by the energy-saving stove 1, the annular cylinder 4, and the circulation box 8 is used to store water to complete the water circulation system. The arc ring frame 7, heated to a high temperature by the burner 6, is used to heat the water in the irregular space, allowing a large amount of water vapor to enter the U-shaped interlayer between the heating box 10 and the U-shaped plate 12 through an L-shaped conduit 9. The water inlet pipe 20 is used to add water to the irregular space.
[0019] As a technical optimization of this utility model, an L-shaped conduit 9 is fixedly connected to the top center of the circulation box 8, and a heating box 10 is fixedly connected to the end of the L-shaped conduit 9 away from the circulation box 8. A horizontal pipe 17 is fixedly connected to the bottom side of the heating box 10.
[0020] As a technical optimization of this utility model, the end of the horizontal pipe 17 away from the heating box 10 passes through the energy-saving stove 1 and is fixedly connected to a water pump 18. The top of the water pump 18 is fixedly connected to a vertical pipe 19. The top of the vertical pipe 19 passes through the energy-saving stove 1 and communicates with the interior of the circulation box 8. The water pump 18 can draw condensate from the U-shaped interlayer through the horizontal pipe 17 and send it back into the irregular space through the vertical pipe 19, where it is heated and boiled again to complete the circulation.
[0021] As a technical optimization of this utility model, the bottom inner wall of the heating box 10 is symmetrically and fixedly connected with a support plate 11. The length of the support plate 11 is the same as the length of the front and rear inner walls of the heating box 10. The top side of the support plate 11 is fixedly connected with a U-shaped plate 12. The support plate 11 is used to reduce the heat transfer from the U-shaped plate 12 to the condensate water, thereby interfering with the heating efficiency of the food.
[0022] As a technical optimization of this utility model, the U-shaped plate 12 is symmetrically and fixedly connected with baffles 13. There is a gap between the baffles 13 and the inner wall of the heating box 10. The length of the baffles 13 is the same as the distance between the front and rear inner walls of the heating box 10. Water vapor will first come into contact with the U-shaped plate 12 and the baffles 13. After being blocked by the baffles 13, the water vapor can flow clockwise along the U-shaped interlayer. The gap between the baffles 13 and the inner wall of the heating box 10 is used for the sliding of condensate.
[0023] As a technical optimization of this utility model, four sliding rails 14 are symmetrically fixedly connected to the inner wall of the U-shaped plate 12. The length of the sliding rails 14 is the same as the distance between the front and rear inner walls of the heating box 10. A shelf 15 is slidably connected between the left and right corresponding sliding rails 14. The upper side of the shelf 15 is used to place food or plates.
[0024] As a technical optimization of this utility model, a pull ring 16 is fixedly connected to one side of the shelf 15. The combined length of the shelf 15 and the pull ring 16 is the same as the length of the slide rail 14. When it is necessary to replace or clean the shelf 15, the shelf 15 can be pulled out from the U-shaped plate 12 by pulling the pull ring 16.
[0025] As a technical optimization of this utility model, a hinged door 21 is symmetrically hinged on one side of the heating box 10, and a handle 22 is fixedly connected to one side of the hinged door 21. The handle 22 is used to open and close the hinged door 21.
[0026] As a technical optimization of this utility model, in use, the user first pours water into the circulation tank 8 through the water inlet pipe 20. The water flows into the irregular space formed by the energy-saving stove 1, the annular cylinder 4, and the circulation tank 8. Then, the food to be heated is placed on the upper side of the shelf 15. At this time, the ignition is started through the regulating valve 2, and the cooking process begins. When a large amount of condensate flows to the bottom of the heating tank 10, the water pump 18 is started. The water pump 18 draws the condensate from the U-shaped interlayer through the horizontal pipe 17 and sends it back into the irregular space through the vertical pipe 19. After being heated and boiled again, the water circulation is completed. After a period of time, the food to be heated will be heated. The hinged door 21 can be opened by the handle 22. After the heat in the rectangular space is released to the outside air, the food can be taken out. When the food is no longer needed, the water pump 18 can be turned off, thereby reducing unnecessary energy waste.
