Description

Technical Field

[0001] The utility model relates to a heating tube with no restriction on placement angle. Background Art

[0002] An instant water heater instantly heats water as it passes through a heating element. Traditional instant water heaters typically utilize a horizontally positioned heating element to avoid dry-boiling. This is because the traditional heating element has a larger internal cavity and a relatively slow water flow rate. If the heating element is positioned vertically, the water flow may not be timely, which can easily lead to dry-boiling. However, this design limits the angles at which the heating element can be placed, restricting the design of the instant water heater and reducing its flexibility.

[0003] Therefore, how to design a heating tube body that can work stably at different placement angles has become an important research direction in the field of instant water heater technology. Utility Model Content

[0004] The purpose of the utility model is to provide a heating tube which can be placed at any angle without affecting its heating effect.

[0005] The purpose of this utility model is achieved in this way:

[0006] A heating tube with an unrestricted placement angle comprises a heating tube body and a spiral body. The diameter of the spiral body is smaller than the inner diameter of the heating tube body. The spiral body is fixed in the inner cavity of the heating tube body. A water channel for guiding the directional flow of water is formed between the inner wall of the heating tube body and the spiral body. One end of the heating tube body is a water inlet, and the other end of the heating tube body is a water outlet. The water inlet and the water outlet are connected to the inner cavity of the heating tube body. The heating tube body heats the water passing through the water channel.

[0007] Thanks to the introduction of the spiral structure, the heating tube can be placed at any angle without affecting its heating performance. Users are no longer restricted by the placement of the heating tube, which increases the convenience of installation and use.

[0008] The water channel formed by the spiral in the heating tube ensures that even a small flow of water can be quickly guided through, thus avoiding the dry burning problem that is prone to occur in traditional heating tubes when the water supply is insufficient, and improving the safety of use.

[0009] The spiral design allows water to flow along a specific path, increasing water flow speed and heating efficiency. This not only improves the heating effect of the water heater, but also provides hot water more quickly.

[0010] When water flows in the spiral channel, it has more complete contact with the inner wall of the heating tube body, heating more evenly, reducing local overheating or uneven heating, and improving the overall heating performance.

[0011] The design is simple in structure, low in manufacturing cost, and easy to produce and maintain. The combination of the spiral and the heating tube not only improves performance but also maintains structural simplicity, facilitating large-scale promotion and application.

[0012] By optimizing the water flow path and heating efficiency, the design can reduce heat loss, improve energy utilization, help save energy and meet environmental protection requirements.

[0013] The purpose of the utility model can also be solved by the following technical measures:

[0014] Furthermore, the spiral body is a screw, the length of the screw is less than or equal to the length of the heating tube body, and a water channel for guiding water to flow radially along the heating tube body is formed between the threads of the screw and the inner wall of the heating tube body.

[0015] The water channel between the screw thread and the inner wall of the heating tube body guides the water to flow radially, so that the water contacts the inner wall of the heating tube body more fully, improves the heating efficiency and uniformity of the water, and provides a more stable and rapid hot water supply.

[0016] Furthermore, it also includes an end cover and a sealing gasket, the end of the end cover is provided with a water nozzle for water inlet or outlet, the bottom of the end cover is provided with an outer ring and an inner ring, the diameter of the outer ring is larger than the outer diameter of the heating tube body, the diameter of the inner ring is smaller than the inner diameter of the heating tube body, and an annular clamping groove is formed between the outer ring and the inner ring;

[0017] The bottom of the sealing gasket is provided with an annular slot, and the port of the heating tube body is inserted into the annular slot so that the sealing gasket is installed at the end of the heating tube body;

[0018] The end of the heating tube body equipped with a sealing gasket is inserted into the annular clamping groove to connect the heating tube body and the end cover. The sealing gasket seals the gap between the heating tube body and the end cover. At the same time, the inner ring enters the inner cavity of the heating tube body and rests on the spiral body.

[0019] The design of the end cap and sealing gasket ensures a tight connection between the heating tube body and the end cap, eliminating the risk of water leakage. The annular slot structure of the sealing gasket effectively fills the gap at the end of the heating tube body, providing reliable sealing performance.

[0020] By installing a sealing gasket at the end of the heating tube body and inserting it into the annular retaining groove of the end cover, the sealing of the connection part is further strengthened, water leakage is avoided, and the safety and reliability of the equipment are ensured.

[0021] The design of the annular clamping groove and the annular slot makes the connection between the heating tube body and the end cover more convenient and quick, simplifies the installation process, reduces installation time and operation complexity, and improves installation efficiency.

[0022] The inner ring enters the inner cavity of the heating tube body and abuts against the spiral body, thereby enhancing the structural stability of the entire heating tube body, preventing the spiral body from loosening or displacement during use, and ensuring the heating efficiency and stability of the water flow guidance.

[0023] Furthermore, the heating pipe body includes a hollow conduit for water to pass through, an insulating layer and an electromagnetic coil, and the insulating layer is provided on the periphery of the hollow conduit;

[0024] The electromagnetic coil is wound on the insulating layer;

[0025] The electromagnetic coil is energized to generate a changing magnetic field that penetrates the hollow conduit and induces eddy current. The eddy current in the hollow conduit generates heat due to the resistance of the metal to heat the water passing through the hollow conduit.

[0026] When the electromagnetic coil is energized, it generates a changing magnetic field, which penetrates the hollow conduit and induces eddy currents, generating heat inside the conduit. This heating method utilizes the principle of eddy currents to generate heat more quickly and evenly, improving the heating efficiency of the water heater.

[0027] Because the eddy current heating method has high efficiency and low energy loss, it can better utilize electrical energy, and the heating process is more energy-saving and environmentally friendly, which helps to reduce energy consumption and reduce environmental pollution.

[0028] The multi-layer structure of the hollow conduit and insulation layer effectively isolates the electromagnetic coil from the water flow, preventing leakage accidents. The insulation layer provides electrical insulation protection, ensuring safety during use.

[0029] The multi-layer design of the hollow tube, insulation layer and electromagnetic coil enhances the overall structural strength and stability of the heating tube body and reduces material deformation and damage caused by thermal expansion and contraction.

[0030] The magnetic field generated by the electromagnetic coil can quickly induce eddy currents, and the heating response is rapid. Users can get hot water faster, improving the user experience.

[0031] The eddy current heating method reduces the formation of scale and the risk of scaling inside the heating tube, ensuring long-term efficient operation of the equipment and reducing the need for cleaning and maintenance.

[0032] Furthermore, the heating pipe body includes a hollow conduit for water to pass through, an insulating layer and an electric heating film, and the insulating layer is provided on the periphery of the hollow conduit;

[0034] The electric heating film generates heat when electricity is supplied, and the heat heats the hollow conduit through the insulating layer. The heat generated by the hollow conduit heats the water passing through the hollow conduit.

[0035] When the electric heating film is energized, it quickly generates heat, which is effectively transferred to the hollow conduit through the insulation layer, thereby quickly heating the water flowing through the hollow conduit and achieving instant hot water supply.

[0036] The electric heating film is wrapped around the insulation layer, which can evenly distribute heat, so that the water flow in the hollow conduit is evenly heated, avoiding local overheating or uneven heating problems and improving the user experience.

[0037] The design of the hollow conduit and the insulating layer ensures the isolation of the electric heating film from the water flow, effectively preventing the safety hazards caused by the electric heating film directly contacting the water flow, and ensuring electrical safety during use.

[0038] Compared with traditional heating elements, electric heating film has a simple structure and is easy to install, which reduces manufacturing and maintenance costs and improves product reliability and economy.

[0039] The electric heating film has a fast thermal response speed and can provide hot water quickly, which reduces waiting time, improves usage efficiency and meets users' needs for instant hot water.

[0040] The electric heating film has high thermal efficiency and excellent energy conversion efficiency, which reduces heat loss, improves overall energy efficiency, helps save energy and protect the environment, and reduces operating costs.

[0041] The electric heating film is thin and flexible, which makes the overall structure of the heating tube compact and occupies little space, which is conducive to the compactness and miniaturization of the water heater design and is suitable for various installation environments.

[0042] The electric heating film and insulation layer materials are selected from high quality materials with good high temperature resistance and corrosion resistance, which extends the service life of the heating tube body and reduces the need for frequent replacement.

[0043] The surface of the electric heating film is smooth and not easy to adhere to scale, which reduces the risk of scaling inside the hollow tube, maintains the long-term stability of the heating efficiency, and reduces the workload of cleaning and maintenance.

[0044] Furthermore, the heating pipe body includes a hollow conduit for water to pass through, an insulating layer and a heating wire, and the insulating layer is provided on the periphery of the hollow conduit;

[0045] The heating wire is wound on the insulating layer;

[0046] The heating wire generates heat when energized, and the heat heats the hollow conduit through the insulating layer. The heat generated by the hollow conduit heats water passing through the hollow conduit.

[0047] When the heating wire is energized, it quickly generates heat, which is effectively transferred to the hollow conduit through the insulation layer, thereby quickly heating the water flowing through the hollow conduit and achieving instant hot water supply.

[0048] The heating wire is wrapped around the insulation layer, which can evenly distribute heat, so that the water flow in the hollow conduit is evenly heated, avoiding local overheating or uneven heating problems and improving the user experience.

[0049] The design of the hollow conduit and the insulating layer ensures the isolation of the heating wire from the water flow, effectively preventing the safety hazards caused by the heating wire directly contacting the water flow, and ensuring electrical safety during use.
