[0029] An electric water heater is a common household water heater that uses electricity to heat tap water or other suitable water to a set temperature for daily use. It typically consists of a water tank and one or more heating elements. The heating elements heat the water in the tank to achieve this.

[0030] In the related art, the heat exchange component is used to exchange heat with the water in the hot water tank to achieve heating of the water inside the heat exchange component. Usually, the heat exchange component is fixed to the side wall of the hot water tank through a fixing part or a fixed structure. This fixing method requires multiple fixed points for fixed connection, resulting in cumbersome fixing and connection procedures, high processing costs, and weak stability of the heat exchange component connection.

[0031] Regarding the problems in related technologies, such as Figure 1 、 Figure 2As shown, the present invention provides an electric water heater, comprising a housing 10, a heat exchange assembly 20, a support member 30, and a heater 50. The housing 10 defines a liquid storage space 14. The heat exchange assembly 20 is connected to the sidewall of the housing 10 and is located within the liquid storage space 14. The support member 30 is connected to the housing 10 and is used to support the heat exchange assembly 20. The heater 50 is connected to the housing 10 and is used to heat the liquid within the liquid storage space 14. The heat exchange assembly 20 is used to exchange heat with the medium within the liquid storage space 14, thereby heating the cold water within the heat exchange assembly 20. To achieve efficient heat exchange, the heat exchange assembly 20 is often a spiral or spiral structure to increase the contact area with the medium within the liquid storage space 14. In this embodiment, the support member 30 is provided so that the entire heat exchange assembly 20 is supported and connected by the support member 30, improving the overall support stability and facilitating assembly.

[0032] Generally speaking, the heat exchange assembly 20 in an electric water heater is constructed in the form of a spiral or convoluted pipe. The heat exchange assembly 20 has two interfaces: one for cold water input and the other for hot water output. To facilitate connection to the piping system, the cold water input and hot water output interfaces are typically located on the housing 10 and connected to the external piping system. In the solution of this embodiment, a support member 30 is provided within the housing 10 to support the heat exchange assembly 20. Especially when the heat exchange assembly 20 is long, the support of the support member 30 can significantly improve the overall stability.

[0033] Specifically, in this embodiment, the cold water input and hot water output ports of the heat exchange assembly 20 are connected to the side walls of the housing 10. The connection to the housing 10 itself provides minimal support, primarily serving to connect the ports to the piping system. The entire structure of the heat exchange assembly 20 is located within the liquid storage space 14 and is supported by a support member 30.

[0034] In the specific configuration, the box body 10 is constructed as a flat rectangular box body 10 structure. The configuration of the flat box body 10 can save installation space and facilitate the installation of the box body 10.

[0035] Among them, the electric water heating device can be a non-pressurized water heater, that is, in this embodiment, a liquid storage space 14 is provided to connect to the outside world, ensuring that the pressure in the liquid storage space 14 is similar to that of the outside world, and no additional pressure is generated on the inner wall of the box body 10. Therefore, the box body 10 does not need to be set to a pressure-bearing shape (such as a barrel shape), and the shape of the box body 10 can be adaptively adjusted according to the spatial layout requirements of the location of the water heater, thereby improving space utilization and achieving the stability of the flat box body 10 structure.

[0036] In a specific embodiment, a communication port is opened on the upper part or top of the box body 10, and the communication port is connected to the liquid storage space 14, so that the pressure in the liquid storage space 14 is close to that of the outside, avoiding additional pressure on the inner wall of the box body 10.

[0037] It can be understood that when the heat exchange component 20 is arranged in a cylindrical or flat rectangular box 10, in order to improve the heat exchange efficiency, the heat exchange component 20 is often arranged in most of the liquid storage space 14, which makes the spiral or spiral shape longer, which will cause shaking problems during transportation or input of cold water. In this embodiment, the heat exchange component 20 is supported by the support member 30, so that the heat exchange component 20 can be stably arranged, ensuring the stability of the heat exchange component 20, avoiding large shaking during transportation or input of cold water, and improving the quality of the product.

[0038] According to some embodiments provided by the present invention, the support member 30 includes a rod-shaped support member 30, which is connected to the housing 10 and is located in the liquid storage space 14. A portion of the support member 30 contacts the heat exchange assembly 20 to support the heat exchange assembly 20. The support member 30 is an entire rod-shaped support rod structure, which is arranged in the housing 10 to form an integral support structure. The heat exchange assembly 20 can be arranged on the support rod to achieve support for the heat exchange assembly 20. This method makes the connection of the heat exchange assembly 20 more stable.

[0039] Specifically, there are multiple support members 30, and the multiple support members 30 are connected to the box body 10 and located in the liquid storage space 14 to form a support structure. The overall structure of the heat exchange component 20 is located in the liquid storage space 14 and is supported by the support structure formed by the multiple support members 30.

[0040] For example, multiple support members 30 are spaced apart and connected within the housing 10, with one end extending outward (not shown), thereby forming a support platform. The spiral space of the heat exchange assembly 20 is located on the support platform and supported by the support platform. Of course, two or more support members 30 can also provide vertical positioning of the heat exchange assembly 20 to prevent it from shaking.

[0041] It will be appreciated that this embodiment provides a specific structure for the support member 30, namely, a support rod. Those skilled in the art will appreciate that the separately provided support member 30 may alternatively be a bracket, support block, or other structure, as long as it can independently support the heat exchange assembly 20. The use of support rods in this embodiment facilitates overall assembly and installation, and helps control overall equipment costs.

[0042] In some embodiments, the support member 30 is disposed between two opposing walls of the housing 10, with one end of the support member 30 fixedly connected to one side wall of the housing 10 and the other end of the support member 30 plugged into the other side wall of the housing 10. The support member can provide support for the heat exchange assembly 20, and plugging one end of the support member 30 facilitates assembly, simplifies the assembly process, and improves production efficiency in mass production.

[0043] In this embodiment, the support member 30 is arranged between two opposite side walls. After the support member 30 is connected, a support structure similar to a beam is formed. The tubular structure of the heat exchange component 20 when it is spiraled or coiled usually enables the support member 30 to pass through the spiral space or coiled space on the heat exchange component 20 to support the heat exchange component 20.

[0044] Specifically, one end of the support member 30 and the heat exchange assembly 20 are fixedly connected to one side wall of the box body 10, and a socket is provided on the other side wall opposite to the box body 10, which facilitates the overall installation.

[0045] During installation, first, one end of the support member 30 and the heat exchange component 20 are arranged on the side wall of the box body 10 by welding or bolting. At this time, the entire rod body of the support member 30 is in the supporting position, and then a socket structure is formed on the other opposite side wall of the box body 10. During installation, the end of one end of the support member 30 and the socket structure are plugged in, so that the support member 30 spans the liquid storage space 14 to support the heat exchange component 20.

[0046] In a specific configuration, the support member 30 is a rod-shaped steel bar. The steel bar has a high structural strength, can improve its bearing capacity, and achieve stable bearing of the heat exchange component 20 .

[0047] In some embodiments, such as Figure 2 、 Figure 3 As shown, a positioning buckle 60 is provided on the inner wall surface of at least one side wall of the box body 10. The positioning buckle 60 has a positioning hole 61, and one end of the support member 30 is inserted into the positioning hole 61. The provision of the positioning buckle 60 can improve the efficiency of mass production and reduce the overall production cost.

[0048] Specifically, the positioning buckle 60 is arranged on the side wall of the box body 10 by welding, and the aperture of its positioning hole 61 is slightly larger than the rod diameter of the end of the rod-shaped support member 30, so that the support member 30 can be inserted into the positioning hole 61 to achieve the connection of the support member 30.

[0049] It is understandable that if Figure 3As shown, the positioning buckle 60 is a sheet metal or plastic part that can be processed separately from the side wall of the box body 10, improving the flexibility of overall product production. In other words, the positioning buckle and the box body 10 can be processed separately and connected by welding after each processing is completed. This method facilitates batch production and improves product production efficiency.

[0050] In some embodiments, the housing 10 includes a main body 11, a first end plate 12, and a second end plate 13. The main body 11 has one end and the other end disposed opposite each other. The first end plate 12 is connected to one end of the main body 11, and the second end plate 13 is connected to the other end of the main body 11. The housing 10 adopts a split structure. The split design makes transportation and installation more convenient because each part can be handled separately, saving space and cost.

[0051] Specifically, the width of the main body 11 is greater than its thickness, and the length of the main body 11 is greater than its width, resulting in a flat structure. The main body 11 has opposite ends along its length. The first end plate 12 and the second end plate 13 are connected to the corresponding ends to form a sealed box 10 structure and a liquid storage space 14.

[0052] like Figure 1 As shown, the first end plate 12 is provided with bolt holes corresponding to the studs provided on one end of the main body 11. A sealing ring is also provided on the end surface of the main body 11. This seals the first end plate 12 and the end surface of the main body 11 together after connection, preventing leakage of the medium within the liquid storage space 14. The second end plate 13 is provided with a positioning buckle 60, which is welded to the second end plate 13. The second end plate 13 is also welded to the end surface of the other end of the housing 10. This welding ensures a sealed connection with the second end plate 13 while also ensuring the connection strength of the second end plate 13.

[0053] It can be understood that after the first end plate 12 and the second end plate 13 are connected to the main body 11, two opposite side walls of the box body 10 are formed, and the support member 30 is connected between the first end plate 12 and the second end plate 13, thereby forming a support beam in the length direction of the liquid storage space 14, thereby achieving support for the heat exchange component 20 in the length direction, thereby achieving effective support for the heat exchange component 20.

[0054] In some embodiments, the heat exchange assembly 20 is connected to the inner sidewall of the first end plate 12, and the water inlet and outlet ports of the heat exchange assembly 20 are located on the first end plate 12. The heat exchange assembly 20 is formed by piping wound into a specific shape. In this embodiment, the water inlet and outlet ports of the heat exchange assembly 20 are located on the first end plate 12 to facilitate connection of the piping system.

[0055] Specifically, the heat exchange assembly 20 needs to be connected to a pipeline system to input cold water and output hot water. In this embodiment, two ports are provided on the same end plate to facilitate the connection of the pipeline system.

[0056] According to some embodiments of the present invention, patterned protrusions are formed on the sidewalls of the main body 11. The patterned protrusions can enhance the structural strength of the main body 11, so that the main body 11 has better pressure-bearing capacity.

[0057] It can be understood that the main body 11 as a whole has a large contact area with the water inside the box 10, and the main body 11 needs to withstand pressure when heated. In this embodiment, the patterned structure can make the structural strength of the box 10 higher and achieve higher pressure resistance.

[0058] In some embodiments, a portion of the support member 30 is provided with an anti-wear rubber strip 40. When the support member 30 supports the heat exchange assembly 20, it needs to contact and support the heat exchange assembly 20. In this embodiment, the provision of the anti-wear rubber strip 40 prevents friction between the support member 30 and the heat exchange assembly 20.

[0059] like Figure 2 As shown, the anti-wear strip 40 is mounted on the rod of the support member 30 and arranged along the length of the support member 30, so that the anti-wear strip 40 covers the entire heat exchange assembly 20, preventing friction with the heat exchange assembly 20. The support member 30 is an overall rod-shaped structure, which can facilitate the mounting of the anti-wear strip 40 and achieve quick installation of the anti-wear strip 40.

[0060] According to one embodiment of the present invention, the heat exchange assembly 20 is constructed as a cylindrical spiral structure, with a heating space 22 formed inside the spiral structure. At least a portion of the heater 50 is located within the heating space 22. The spiral structure can extend the water path in the liquid storage space 14 and increase the contact area with the water in the liquid storage space 14, thereby improving heat exchange efficiency.

[0061] Specifically, the heat exchange pipeline is surrounded to form a spiral structure and is cylindrical as a whole, thereby forming a spring-like annular water channel, and a heating space 22 is formed in the center of the spiral structure. The water in the liquid storage tank enters the heating space 22 to heat the heat exchange component 20.

[0062] The heat exchange assembly 20 may include a multi-layer spiral structure, with adjacent spiral structures connected in series so that the input cold water passes through all the spiral structures before being output. In the multi-layer spiral structure, a heating element 50 is provided in the heating space 22 of at least one layer.

[0063] In a specific example, Figure 2As shown, the heat exchange component 20 includes a three-layer spiral structure, and a heating element 50 is provided in the heating space 22 of the lowest layer of the spiral structure. The heating element 50 can heat the water in the liquid storage space 14, and can also directly heat the cold water input into the heat exchange component 20, thereby improving the heat supply to the cold water inlet port of the heat exchange component 20, so that the unit heat received by the heat exchange component 20 in this section is higher, thereby improving the heat exchange efficiency.

[0064] It can be understood that the heat exchange efficiency of the heat exchange component 20 can be improved by disposing the heating element 50. The heating element 50 is located in the heating space 22 and can directly heat the heat exchange component 20 at this position.

[0065] According to the electric water heater provided by the present invention, a support member 30 is provided on the outside of the heat exchange assembly 20. The support member 30 abuts against the sidewall of the heat exchange assembly 20 to limit the shaking of the heat exchange assembly 20. After the heat exchange assembly 20 is installed in the liquid storage space 14, it is supported by the support member 30. In this embodiment, the support member 30 is provided on the outside of the heat exchange assembly 20. The provision of the support member 30 can limit the shaking of the heat exchange assembly 20, thereby achieving the positioning of the heat exchange assembly 20 and improving the stability of the installation of the heat exchange assembly 20.

[0066] Specifically, the heat exchange assembly 20 will produce an outward displacement when shaking. The arrangement of the support member 30 on the outer side wall can prevent the heat exchange assembly 20 from being displaced, thereby preventing shaking and improving the stability of the heat exchange assembly 20.

[0067] For example, support members 30 may be provided at various positions of the heat exchange assembly 20 so that the heat exchange assembly 20 is located within the space defined by the support members 30 to prevent the heat exchange assembly 20 from shaking.

[0068] According to the electric water heater provided by the present invention, the heat exchange assembly 20 is constructed as a cylindrical spiral structure. The interior of the spiral structure forms an internal space 21 for the support member to pass through. The ends of the support member 30 are fixedly connected to the housing 10. In addition to configuring the internal space 21 of the spiral structure as the heating space 22 as described above, the entire heat exchange assembly 20 is supported by the support member 30 passing through the internal space 21. This ensures that the spiral heat exchange assembly 20 can be fully supported by the support member 30, preventing internal collapse, and improving the stability of the support.

[0069] Specifically, in the multi-layer heat exchange component 20, each layer is an independent spiral structure, and a support member 30 is provided in each layer to support each layer of the spiral structure. The support member 30 in the spiral mechanism located in the top layer is provided on the outside of the top of the heat exchange component 20 to achieve the limitation of the heat exchange component 20.

[0070] like Figure 2As shown, the heat exchange assembly 20 includes a three-layer spiral structure. Support members are provided in the first and second spiral layers from bottom to top. Support members 30 span the corresponding heating spaces 22 and the two internal spaces 21 above the heating spaces 22 to support the main body of the heat exchange assembly 20. Support members 30 are provided on the outside of the third spiral structure, contacting and abutting the outer wall of the third spiral structure to limit the shaking of the heat exchange assembly 20. Of course, a spiral structure with two or more layers can also be used, which can still use similar structures to achieve support and positioning.

[0071] During the specific setting, any other method can be used for the arrangement of the support member 30, as long as a support member 30 for limiting is provided on the outside of the heat exchange component 20. The setting of the outer limiting support member 30 can improve the stability of the connection of the heat exchange component 20 and prevent the heat exchange component 20 from shaking.

[0072] In some embodiments, the support members 30 are arranged along the extension direction of the heat exchange assembly 20, and each roll of heat exchange assembly 20 is provided with at least two support members 30. The support members 30 are arranged at intervals to support each roll of heat exchange assembly 20. The load-bearing capacity of a single support member 30 is limited, but using two or more support members 30 can effectively increase the load-bearing capacity, thereby improving overall stability.

[0073] Specifically, the plurality of spaced support members 30 can increase the contact area with the heat exchange assembly 20 , thereby achieving a higher load-bearing capacity.

[0074] like Figure 1 、 Figure 2 As shown, the heat exchange assembly 20 includes a three-layer spiral structure, and each layer of the spiral structure is provided with two spaced support members 30. The two support members 30 are spaced side by side to improve the overall bearing capacity.

[0075] It should be noted that the description and drawings of this embodiment all use two rod-shaped support members 30 (i.e., support rod structures) as examples, but those skilled in the art should know that when the diameter of the spiral structure is large, the number of support rods can be increased to achieve effective support for the heat exchange component 20 and improve its load-bearing capacity.

[0076] Through the description of the above embodiments, those skilled in the art can clearly understand that in each embodiment, the heat exchange assembly 20 is connected to the side wall of the housing 10, and the heat exchange assembly 20 is supported as a whole by the support member 30, which can achieve stable support for the heat exchange assembly 20, simplify the product assembly process, and reduce manufacturing costs. Furthermore, the housing 10 adopts a split structure, which is conducive to mass production and improves production efficiency. Furthermore, by providing the support member 30 on the outside of the heat exchange assembly 20, the support member 30 can play a limiting role, thereby making the heat exchange assembly 20 more stable and improving the stability of the device.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
