Description

Technical Field

[0001] The present application relates to the technical field of electric heating tubes, and in particular to an integrated electric heating tube. Background Art

[0002] With the continuous development of the electrical machinery manufacturing industry, electric heating tubes, as an electric heating device, are often used for heating liquids. Therefore, electric heating tubes are widely used in many fields such as industry, agriculture, and home appliances. In the field of home appliances, our common water heaters use electric heating tubes. In addition, electric heating tubes can also be used in rice cookers, microwave ovens, bread makers and other household appliances.

[0003] Reference Figure 1 The electric heating tube in the prior art is usually composed of a plurality of U-shaped heating tubes 6, which are fixed by a flange 7. The current passes through the U-shaped heating tube 6 to heat the electric heating wire inside it, and the heat generated by the electric heating wire is conducted to the liquid through the U-shaped heating tube 6, thereby heating the liquid. Then, when the liquid medium to be heated has a higher temperature requirement or a larger liquid capacity, in order to meet the above heating requirements, more U-shaped heating tubes 6 are needed to assemble the electric heating tube so that the electric heating tube has a greater power. However, a large number of U-shaped heating tubes 6 have the problem of complicated operation during the loading and unloading process. Utility Model Content

[0004] In order to improve the above problems in the prior art, the present application provides an integrated electric heating tube.

[0005] The present application provides an integrated electric heating tube, which adopts the following technical solution:

[0006] An integrated electric heating pipe comprises a heating pipe fitting, wherein the heating pipe fitting comprises two straight pipe fittings and a serpentine pipe fitting arranged between the two straight pipe fittings, the serpentine pipe fitting and the straight pipe fitting are bent and formed as one piece, and the two straight pipe fittings are connected by a mounting flange.

[0007] By adopting the above technical scheme, the heating pipe fitting of the present application is composed of two straight pipe fittings and a serpentine pipe fitting between the two straight pipe fittings. Compared with the U-shaped heating pipe in the prior art, the power of a heating pipe fitting of the present application is greater than or equal to the power of at least two U-shaped heating pipes in the prior art. This reduces the number of heating pipe fittings required for the total power required for the liquid medium to be heated, and therefore the integrated electric heating pipe is more convenient to load and unload.

[0008] Optionally, the heating pipe is configured as a W-shaped structure.

[0009] By adopting the above technical solution, a single W-shaped heating pipe has higher power than a single U-shaped heating pipe.

[0010] Optionally, the serpentine pipe is configured as a W-shaped structure.

[0011] By adopting the above technical solution, a heating pipe fitting in which only the serpentine pipe fitting is a W-shaped structure has higher power than a heating pipe fitting in which only the serpentine pipe fitting is a W-shaped structure.

[0012] Optionally, a plurality of the heating pipes are provided, and the serpentine pipes of the plurality of the heating pipes are staggered with respect to each other.

[0013] By adopting the above technical solution, when multiple heating pipes are arranged to increase the power of the electric heating pipe, the serpentine pipes are staggered with each other, which can ensure that there is enough space between the multiple heating pipes for installation.

[0014] Optionally, a plurality of the heating pipes are connected and fixed via a reinforcing disc, and the reinforcing disc is provided with a fixing hole for the heating pipe to pass through.

[0015] By adopting the above technical solution, when the number of heating pipes is large and the length is long, there will be a lack of stability. In this case, the reinforcing disc can provide support for the heating pipes, making the overall structure of the heating pipes more stable and firm.

[0016] Optionally, the reinforcement disc has a plurality of flow-through notches distributed along its circumference.

[0017] By adopting the above technical solution, when the heated liquid is in a flowing state, the liquid can keep flowing in the container through the flow notch on the reinforcing disc. In this way, when the heating pipe heats the liquid, it can be ensured that the reinforcing disc will not block the flow of the heated liquid, thereby ensuring that the heating pipe can smoothly heat the flowing liquid.

[0018] Optionally, a thermocouple is arranged between the plurality of heating pipes, and the thermocouple is fixedly connected to the mounting flange.

[0019] By adopting the above technical solution, a thermocouple is set to monitor the temperature of the heated liquid. When the temperature of the heated liquid reaches the set temperature value, the heating pipe will stop heating.

[0020] Optionally, a sealing ring is provided along the circumferential direction on the end surface of the mounting flange facing the heating tube.

[0021] By adopting the above technical solution, the mounting flange on the electric heating tube and the flange on the container are installed in matching pairs, and the sealing ring between the two flanges prevents the liquid inside the container from leaking out.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. The heating pipe fitting of the present application is composed of two straight pipe fittings and a serpentine pipe fitting between the two straight pipe fittings. Compared with the U-shaped heating pipe in the prior art, the power of a heating pipe fitting of the present application is greater than or equal to the power of at least two U-shaped heating pipes in the prior art. This reduces the total power required for the liquid medium to be heated, so the integrated electric heating pipe is more convenient to load and unload.

[0024] 2. A single W-shaped heating pipe has higher power than a single U-shaped heating pipe. Furthermore, a single heating pipe in which only the serpentine pipe is a W-shaped heating pipe has higher power than a single W-shaped heating pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 2-3 This application is described in further detail.

[0030] Embodiment 1

[0031] This embodiment discloses an integrated electric heating tube. Figure 2 The integrated electric heating tube includes a heating tube 1. Specifically, the heating tube 1 is composed of two straight tubes 11 and a serpentine tube 12 connected between the two straight tubes 11. The two straight tubes 11 and the serpentine tube 12 are actually formed by integral bending. In this embodiment, the heating tube 1 is a W-shaped structure as an example, that is, the serpentine tube 12 is equivalent to a U-shaped structure. Obviously, compared with the U-shaped heating tube in the prior art, the W-shaped heating tube 1 has higher power. For the total power required for the liquid medium to be heated, the number of W-shaped heating tubes 1 required to be used will be reduced, so the integrated electric heating tube is more convenient to load and unload.

[0032] Reference Figure 2 In this embodiment, two heating pipes 1 are taken as an example. The integrated electric heating pipe is actually composed of two heating pipes 1 and a mounting flange 2. Specifically, the serpentine pipes 12 of the two heating pipes 1 are staggered, and the two heating pipes 1 are vertically distributed, and the straight pipes 11 of the two heating pipes 1 are connected and fixed to the mounting flange 2 to form the integrated electric heating pipe of this embodiment. A thermocouple 4 is arranged between the two heating pipes 1. The thermocouple 4 is also connected and fixed to the mounting flange 2 and is located in the middle of the mounting flange 2. The thermocouple 4 can monitor the temperature of the heated liquid medium. When the temperature of the heated liquid reaches the set temperature value, the heating pipe 1 will stop heating.

[0033] Reference Figure 2 , a reinforcing disc 3 is sleeved on the two heating pipe fittings 1, and the connection and fixation between the two heating pipe fittings 1 are achieved through the fixing holes 31 on the reinforcing disc 3, which provides support for the heating pipe fittings 1 with a longer length, thereby improving the stability of the overall structure of the heating pipe fittings 1. In addition, a plurality of flow gaps 32 are opened on the reinforcing disc 3, and the plurality of flow gaps 32 are evenly distributed along the circumferential direction of the reinforcing disc 3. The liquid can maintain a flowing state in the container through the flow gaps 32, so that the heating pipe fittings 1 can better heat the liquid and improve the heating effect. Then, in order to prevent the liquid inside the container from leaking out, a rubber sealing ring 5 is provided on the side of the mounting flange 2 facing the heating pipe fitting 1, and the sealing ring 5 is arranged along the circumferential direction of the mounting flange 2. The mounting flange 2 on the electric heating tube and the flange on the container are installed in pairs, and the sealing ring 5 between the two flanges can prevent the liquid inside the container from leaking out.

[0034] The implementation principle of an integrated electric heating tube in the present embodiment is: the straight section pipe fittings 11 of each of the two heating pipe fittings 1 are connected and fixed to the mounting flange 2 to form the integrated electric heating tube in the present embodiment. The W-shaped heating pipe fittings 1 in the present embodiment have higher power than the U-shaped heating pipe fittings in the prior art. Therefore, the number of W-shaped heating pipe fittings 1 required for the total power required for the liquid medium to be heated will be reduced, and thus the integrated electric heating tube is more convenient to load and unload.

[0035] Embodiment 2

[0036] The technical solution of this embodiment is different from that of the first embodiment in that Figure 3The serpentine pipe fitting 12 is arranged in a W-shaped structure, while the serpentine pipe fitting 12 in the first embodiment is a U-shaped structure. Therefore, the heating pipe fitting 1 in this embodiment has a higher efficiency than the heating pipe fitting 1 in the first embodiment. For the total power required for the liquid medium to be heated, the number of heating pipe fittings 1 in this embodiment that need to be used will be less, so it is more convenient to load and unload.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
