[0021] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to the implementation mode, and other implementation modes may also fall within the scope of the present invention as long as they meet the purpose of the present invention.

[0022] In a preferred embodiment of the present utility model, based on the above problems existing in the prior art, a spiral heating container is provided. Figure 1 and Figure 2 As shown, including:

[0023] A barrel body 1, the barrel body 1 is respectively covered with an upper cover 2 and a lower cover 3, the upper cover is provided with a water return port 21, the lower cover is provided with a water outlet 31, and the directions of the water return port 21 and the water outlet 31 are tangent to the barrel body 1 along the diameter direction of the barrel body;

[0024] The barrel body is provided with an electric heating pipe fixing port 4, and the electric heating pipe fixing port 4 is connected with a straight tube 5 extending into the barrel for placing the electric heating pipe.

[0025] Specifically, in the present embodiment, a spiral heating container is provided. Before use, the container is first filled with water (it can be water or other types of liquids). When in use, water (the same as the liquid injected above) is injected through the water return port, and the heated water is discharged through the water outlet. Since the directions of the water return port and the water outlet are tangent to the barrel body, the injected water will flow along the inner wall of the barrel body in the barrel to form a spiral water flow. The flow rate of the spiral water flow will be faster, thereby improving the heating efficiency, and the water will flow through every corner of the barrel to avoid the problem of uneven heating.

[0026] In this embodiment, heating is performed by electric heating tubes, so an electric heating tube fixing port 4 is provided on the barrel body 1, and a straight cylinder 5 extends inward from the electric heating tube fixing port 4. The straight cylinder 5 is not connected to the inside of the barrel, and an electric heating tube is placed in the straight cylinder 5 for heating.

[0027] When the water flows through the straight cylinder 5, it will generate disturbances. Water flow disturbance is a physical concept, which refers to the intermittent switching and mixing phenomenon of the fluid (here is water) during the movement, forming an irregular area of ​​flow density, which in turn causes a large loss of fluid kinetic energy. Therefore, the water flow around the straight cylinder will surround or stay around the straight cylinder for a certain period of time so that it can be fully heated. Since the entire container is filled with water, and the return water port 21 takes in water, and the water outlet 31 discharges water synchronously, the water flow around the straight cylinder 5 will flow to the water outlet 31 under the action of pressure, and continue to form a spiral water flow. That is, the whole process is to first form a spiral water flow, then turbulent flow heating around the straight cylinder, and finally form a spiral water flow to discharge and complete the heating process.

[0028] During the whole process, the spiral water flow has a fast flow rate, so the whole process is fast and efficient, and a turbulent flow is formed around the straight cylinder 5, which can fully exchange heat and avoid insufficient heating. Since the container is filled in advance and a spiral water flow is formed, all the water in the container will flow through the straight cylinder 5, which can also avoid uneven heating.

[0029] In a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, an automatic exhaust port 22 and a drain port 23 are provided on the top of the upper cover 2 .

[0030] Specifically, in this embodiment, it is mentioned in the above embodiment that the entire container needs to be filled with water without leaving any air before the heat exchange begins. Therefore, an exhaust port 22 and a drain port 23 are provided on the upper cover. When water is added, the water outlet 31 is closed first, and then water is added from the water return port 21. As the amount of water increases, the air in the container is gradually discharged from the automatic exhaust port 22. When the air is discharged, water flows out of the drain port 23, indicating that the container is now completely filled with water and the heat exchange process can be carried out.

[0031] In a preferred embodiment of the present invention, Figure 3 and Figure 2 As shown, the water return port 21 and the water outlet 31 are located on the same vertical line, and the water return port 21 and the water outlet 31 are in opposite directions.

[0032] Specifically, in this embodiment, the water return port 21 and the water outlet 31 are arranged on the same vertical line and in opposite directions, so that a spiral water flow can be better formed.

[0033] In a preferred embodiment of the present invention, Figure 2 As shown, the upper cover 2 and the lower cover 3 are spherical.

[0034] Specifically, in this embodiment, the upper and lower covers are both spherical, which can reduce dead angles in the container and avoid uneven heating.

[0035] In a preferred embodiment of the present invention, Figure 4 As shown, it includes a plurality of electric heating pipe fixing openings 4, and each electric heating pipe fixing opening 4 is arranged in a vertical direction.

[0036] Specifically, in this embodiment, multiple electric heating tubes are provided. For example, three electric heating tube fixing ports 4 are provided as shown in the figure, which can increase the number of heat sources and improve the heat exchange efficiency. Moreover, they are arranged vertically from top to bottom, which can improve the turbulence effect, increase the heat exchange time and improve the heating effect.

[0037] In a preferred embodiment of the present invention, Figure 4 As shown, the electric heating pipe fixing opening 4 forms a fixing portion 41 radially outward, and a plurality of fixing screw holes 42 are provided on the fixing portion 41 , and the electric heating pipe is fixed on the fixing portion 41 by the cooperation of bolts and screw holes.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
