It is an indispensable piece of equipment in manufacturing, enabling convenient use of hot water in production. However, current hot water boilers have a relatively small internal water heating surface area, resulting in slow water heating. Therefore, there is an urgent need to design an instantaneous hot water boiler to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide an instant hot water boiler to address the aforementioned shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An instantaneous hot water boiler includes a tank body. An upper plate and a lower plate are welded inside the tank body. Inner heat exchange tubes, middle heat exchange tubes, and outer heat exchange tubes are welded evenly distributed between the upper and lower plates. An upper cavity is provided at the top of the upper plate, and a lower cavity is provided at the bottom of the lower plate. An inner cylinder is welded between the upper and lower plates. A jacket is provided between the inner cylinder and the tank body. A water inlet pipe is welded to one outer wall of the tank body and communicates with the jacket. Evenly distributed through holes are opened on the top outer wall of the lower plate, and the jacket communicates with the lower cavity through these through holes. A water outlet pipe is welded to the top outer wall of the tank body, and a burner is fixed to the top outer wall of the tank body.

[0005] Furthermore, a mounting plate is fixed to the top outer wall of the tank, the mounting plate is fixed to the burner, and the bottom end of the burner extends into the interior of the tank.

[0006] Furthermore, the top outer wall of the tank is provided with a central hole, and the burner is inserted into the interior of the central hole.

[0007] Furthermore, the top outer wall of the tank is welded with evenly distributed studs, which penetrate the mounting plate. Nuts are connected to the external threads of the studs, and the nuts are located at the top of the mounting plate.

[0008] Furthermore, a smoke outlet pipe is fixed to one side of the outer wall of the inner cylinder, and the smoke outlet pipe extends to the outside of the tank.

[0011] In the above technical solution, the instant hot water boiler provided by this utility model has the following advantages: the water to be heated flows into multiple heat exchange tubes, and the heat exchange tubes are heated by the burner, thereby increasing the heating area of ​​the water and achieving a faster and more rapid heating effect. Furthermore, the water flows from the lower cavity into the upper cavity, making the heat exchange tubes more full and preventing the heat exchange tubes from burning through due to trapped air. The arc-shaped bottom allows scale that falls into the lower cavity to be easily discharged through the drain pipe during rinsing. A jacket is installed between the tank and the inner cylinder, allowing the water entering the jacket to recover heat from the inner wall of the inner cylinder, thus achieving a high heat utilization rate for the hot water boiler. Simultaneously, the water is preheated before entering the heat exchange tubes, further enhancing the rapid heating effect.

The top outer wall of the lower plate 3 has a uniform opening. The tank 1 has 6-12 evenly distributed through holes 22, preferably 8. The jacket 21 is connected to the lower cavity 7 through the through holes 22. A water outlet pipe 13 is welded to the top outer wall of the tank 1, and the water outlet pipe 13 is connected to the upper cavity 4. In use, water is introduced into the jacket 21 through the through holes 22. The water passes through the through holes 22 and enters the lower cavity 7. After filling the lower cavity 7, the water enters the inner heat exchange tube 6, the middle heat exchange tube 15, and the outer heat exchange tube 16. Then, the water enters the upper cavity 4 and flows out through the water outlet pipe 13. The top outer wall of the tank 1 is solid. A burner 11 is provided, and the flame generated by the burner 11 heats the inner heat exchange tube 6, the middle heat exchange tube 15, and the outer heat exchange tube 16, so that the water inside the inner heat exchange tube 6, the middle heat exchange tube 15, and the outer heat exchange tube 16 can be turned into hot water. A jacket 21 is set between the tank body 1 and the inner cylinder 19, so that the water entering the jacket 21 can recover the heat on the inner wall of the inner cylinder 19, thereby achieving a high heat utilization rate of the hot water boiler.

[0023] In another embodiment of this utility model, a flue pipe 14 is fixed to one side of the outer wall of the inner cylinder 19. The flue pipe 14 extends to the outside of the tank body 1, and the flue gas inside the inner cylinder 19 is discharged from the flue pipe 14. The bottom of the tank body 1 is provided with an arc-shaped bottom 8, which facilitates the collection of dirt. A drain pipe 9 is welded to the bottom outer wall of the arc-shaped bottom 8. The scale that falls into the lower cavity 7 can be easily discharged from the drain pipe 9 during flushing. When the hot water boiler is working, the drain pipe 9 is closed by a valve. The drain valve is only opened when draining, and the boiler is not working at this time. The bottom side wall of the tank body 1 is welded with evenly distributed support legs 20. Preferably, there are four support legs 20, which support the tank body 1.

[0024] Working principle: When using, such as Figure 2 In the diagram, the arrow indicates the direction of water flow. Water is introduced into the jacket 21 through the inlet pipe 12. The water passes through the through hole 22 inside the jacket 21 and enters the lower cavity 7. After filling the lower cavity 7, the water enters the inner heat exchange tube 6, the middle heat exchange tube 15, and the outer heat exchange tube 16. The flame generated by the burner 11 heats the inner heat exchange tube 6, the middle heat exchange tube 15, and the outer heat exchange tube 16, causing the water inside the inner heat exchange tube 6, the middle heat exchange tube 15, and the outer heat exchange tube 16 to quickly turn into hot water. The hot water enters the upper cavity 4 and flows out from the outlet pipe 13. The flue gas inside the inner cylinder 19 is discharged from the flue gas outlet pipe 14.
