Description

Technical Field

[0001] This utility model relates to the field of water heater technology, specifically to a planar spiral tube water heater. Background Technology

[0002] Water heaters mainly include storage water heaters and instantaneous water heaters. Storage water heaters require a large water tank, resulting in a large product size and space occupation. Instantaneous water heaters are relatively lightweight and can provide hot water quickly and for a long time, but the instantaneous water output is smaller and the water pressure is relatively lower.

[0003] To ensure heating efficiency and reduce overall size, water heater heating elements are typically installed in a vertical spiral configuration. This increases the contact time and area between the water and the heating elements, allowing for effective heat transfer. However, increasing heating efficiency and water output requires multiple heating elements. These multiple spirally wound elements, arranged vertically, not only significantly increase the size of the water heater and its space requirements, but also make wiring the heating elements difficult and cumbersome.

[0004] Therefore, the research objective of this utility model is to design a planar spiral water heater that uses flat tube fittings and connectors for inner and outer casing and spaced installation of multiple heating tubes, which are installed in a spiral coiled manner on the same plane. This not only saves a lot of space in the product structure, but also makes the processing simple and easy to implement. Utility Model Content

[0005] In view of the technical problems existing in the prior art, the present invention provides a planar wound-tube water heater, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A planar coiled water heater, comprising:

[0008] A housing, within which a power supply assembly for supplying power to the water heater is installed;

[0009] A flat pipe fitting is fixedly installed inside the housing in a planar spiral arrangement from the inside to the outside, with one end fixedly located in the middle of the housing and connected to a cold water inlet pipe, and the other end fixedly located at the end of the housing and connected to a hot water outlet pipe.

[0010] Multiple heating tubes are arranged side by side at intervals inside the flat tube fitting, and a water channel is formed at the gap between the heating tubes and the flat tube fitting.

[0011] The flat tube has corresponding connectors installed at both ends for spaced and supported installation of the heating tube. Both ends of the heating tube are sealed through the connectors and extend outwards and are electrically connected to the power supply assembly.

[0012] The flat tubes are arranged in a straight line with parallel intervals in the middle, and their ends are arranged in concentric arc intervals. A corresponding receiving cavity is formed on the shell at the middle of the flat tubes spirally wound in the plane for installing the corresponding control board.

[0013] A corresponding temperature controller is installed on the outermost parallel pipe section of the flat pipe fitting's planar spiral, and the temperature controller is electrically connected to the control board.

[0014] The connector is a three-way structure, with its longitudinal ends partially distributed to connect the flat pipe and to seal and fix the heating pipe at intervals, and its transverse end protruding outward and integrally formed with a threaded joint for connecting the cold water inlet pipe or the hot water outlet pipe.

[0015] The threaded connector of the connecting piece located in the middle is connected to the cold water inlet pipe through a corresponding hose. The hose and the threaded connector are detachably connected by tightening the threads. A corresponding flow sensor is installed at the connection between the hose and the cold water inlet pipe. The flow sensor is electrically connected to the control board.

[0016] Inside the housing, a corresponding limiting member is fixedly installed at the position of the arc segment of the flat tube. The upper end of the limiting member is recessed inward and provided with multiple partition grooves. The partition grooves are arranged side by side at intervals, and the arc segment of the flat tube is correspondingly engaged in the partition grooves at intervals.

[0017] The inner wall of the housing is also provided with a wire clamp located on the side of the power supply assembly. The wire clamp is used to clamp and fix the wires connected to the power supply assembly.

[0018] Advantages of this utility model:

[0019] 1) This utility model uses flat tube fittings and connectors to install multiple heating tubes in an inner and outer sleeve arrangement at intervals. The connectors at both ends of the flat tube fittings can not only fix the flat tube fittings so that they can be installed in a planar spiral manner, with the installation on the same plane saving a lot of space in the product structure; and the combination of the rigidity of the connectors and the heating tubes can ensure that multiple heating tubes are installed side by side at intervals inside the flat tube fittings. The processing method is simple and easy to implement. Furthermore, the gap between the heating tubes and the flat tube fittings forms a water channel to ensure the smooth flow of water and to ensure that the heating tubes are completely immersed in water, thereby improving heating efficiency. The connectors can also shape the heating tubes, improve the structural support stability, and enhance the practical effect of this utility model.

[0020] 2) This utility model uses an inner and outer casing method to install multiple heating tubes and flat pipe fittings for water flow, and installs them in a way that wraps around the same plane. This not only saves installation space, but also increases the contact time and contact area between the water flow and the heating tubes, thereby further improving heating efficiency.

[0021] 3) This utility model can achieve the shaping and fixing installation of flat tubes and heating tubes by using connectors and two limiting members. The two connectors at the beginning and end are used for limiting and fixing, and the two limiting members at the top and bottom are used for fixing from the inside to the outside. The two work together to ensure the stability of the support.

[0022] 4) The pipe fittings used for installing heating pipes and circulating water in this utility model adopt a flat structure and are wound with a long strip ring with a parallel straight line in the middle and an arc at the end. Compared with the traditional circular pipe and three-dimensional spiral structure, it can more effectively avoid squeezing the internal heating pipe, avoid the problem of heating pipe deformation due to squeezing and outer pipe rupture, and improve the use effect of this utility model.

[0027] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0028] refer to Figure 1-3 A planar wound-tube water heater, comprising:

[0029] Housing 1, wherein a power supply assembly 2 for supplying power to the water heater is installed inside the housing 1;

[0030] The flat pipe fitting 3 is fixedly installed inside the housing 1 in a planar spiral arrangement from the inside to the outside, with one end fixedly located in the middle of the housing 1 and connected to the cold water inlet pipe 4, and the other end fixedly located at the end of the housing 1 and connected to the hot water outlet pipe 5.

[0031] Multiple heating tubes 6 are arranged side by side at intervals inside the flat tube fitting 3, and a water channel 7 is formed at the gap between the heating tubes 6 and the flat tube fitting 3.

[0032] Connector 8: Both ends of the flat tube 3 are equipped with corresponding connector 8 for spaced and supported installation of the heating tube 6. Both ends of the heating tube 6 are sealed through the connector 8 and extend outward and are electrically connected to the power supply assembly 2.

[0033] This utility model utilizes a flat tube 3 and a connector 8 for the inner and outer casing and spaced installation of multiple heating tubes 6. The connector 8 at both ends of the flat tube 3 not only fixes the flat tube 3, allowing it to be installed in a planar spiral manner with internal and external windings, but also saves a significant amount of space in the product structure due to the same-plane installation. Furthermore, the rigidity of the connector 8 and the heating tubes 6 ensures that multiple heating tubes 6 are installed side-by-side with spacing within the flat tube 3, making the manufacturing process simple and easy to implement. Moreover, the gap between the heating tubes 6 and the flat tube 3 forms a water channel 7, ensuring smooth water flow and ensuring that the heating tubes 6 are completely immersed in water, thus improving heating efficiency. The connector 8 also shapes the heating tubes 6, improving the structural support stability and enhancing the practical effect of this utility model.

[0034] This utility model uses an inner and outer casing method to install multiple heating tubes 6 and flat pipe fittings 3 for water flow, and installs them in a way that surrounds each other on the same plane. This not only saves installation space, but also increases the contact time and contact area between the water flow and the heating tubes 6, thereby further improving heating efficiency.

[0035] The flat tube 3 is arranged in a straight line with parallel intervals in the middle, and its ends are arranged in concentric arc intervals. The shell 1 has a corresponding receiving cavity formed in the middle of the flat tube 3 spirally wound in the plane for installing the corresponding control board 9.

[0036] The pipe fittings used in this utility model for installing the heating tube 6 and the circulating water adopt a flat structure and are wound in a long strip ring with a parallel straight line in the middle and an arc at the end. Compared with the traditional circular pipe and three-dimensional spiral structure, it can more effectively avoid squeezing the internal heating tube 6, avoid the problem of the heating tube 6 being deformed due to squeezing and the outer tube breaking, and improve the use effect of this utility model.

[0037] A corresponding temperature controller 10 is installed on the outermost parallel pipe section of the planar spiral of the flat pipe fitting 3. The temperature controller 10 is electrically connected to the control board 9. The winding method of the flat pipe fitting 3 can provide suitable installation space for the control board 9 and other components based on the control space.

[0038] The connector 8 is a three-way structure, with its longitudinal ends partially distributed to connect the flat pipe 3 and the heating pipe 6 for sealing and fixed installation at intervals, and its transverse end protruding outward and integrally formed with a threaded joint 801 for connecting the cold water inlet pipe 4 or the hot water outlet pipe 5.

[0039] The threaded connector 801 of the connecting piece 8 located in the middle is connected to the cold water inlet pipe 4 through a corresponding hose 11. The hose 11 and the threaded connector 801 are detachably connected by tightening the threads. A corresponding flow sensor 12 is installed at the connection between the hose 11 and the cold water inlet pipe 4. The flow sensor 12 is electrically connected to the control board 9.

[0040] Inside the housing 1, a corresponding limiting member 13 is fixedly installed at the position of the arc segment of the flat tube 3. The upper end of the limiting member 13 is recessed inward and provided with multiple partition grooves. The partition grooves are arranged side by side at intervals. The arc segment of the flat tube 3 is correspondingly locked in the partition grooves at intervals.

[0041] This utility model achieves the shaping and fixing installation of the flat tube 3 and the heating tube 6 by using the connector 8 and two limiting members. The two connectors 8 at the beginning and end are used for limiting and fixing, and the two limiting members at the top and bottom are used for fixing from the inside to the outside. The two work together to ensure the stability of the support.

[0042] The inner wall of the housing 1 is also provided with a wire clamp 14 located on the side of the power supply assembly 2. The wire clamp 14 is used to clamp and fix the wires connected to the power supply assembly 2.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
