Description

Technical Field

[0001] The present application belongs to the technical field of water heaters, and specifically relates to a water heater shell structure and an electric water heater. Background Art

[0002] An electric water heater is a device that uses electricity to heat cold water into hot water. It has many advantages, such as stable water flow, safety and environmental protection, easy installation, and is not easily affected by weather.

[0003] In the prior art, the housing structure of an electric water heater typically consists of a cylindrical shell and end caps that seal the ends of the shell. At least one of the end caps is equipped with a support structure that mates with the ends of the inner pot to stably support the inner pot within the space enclosed by the shell and end caps. During assembly of the electric water heater, both end caps must be assembled separately. Because the support structure is pre-installed on the end caps, the specifications of both the end caps and the shell must be compatible with those of the inner pot.

[0004] As a result, the flexibility of the water heater shell structure is low and the operation is complicated. Utility Model Content

[0005] The present application provides a water heater shell structure and an electric water heater to solve the problems of low flexibility and complicated operation of the existing water heater shell structure.

[0006] On the one hand, the present application provides a water heater housing structure, comprising a housing, a fixing bracket and an end cover, wherein the housing has a receiving cavity, and one end of the housing has an opening communicating with the receiving cavity, and the receiving cavity is used to receive an inner tank of the water heater;

[0007] The fixing bracket is located in the accommodating cavity and is used to abut between the inner container and an end of the shell facing away from the opening. The end cover seals the opening and is used to abut against the inner container.

[0008] In one possible implementation, the water heater shell structure provided in the present application has an end of the fixing bracket facing the opening configured to adapt to the arc surface of the end of the inner tank, and an end of the fixing bracket facing away from the opening abuts against the end surface of the shell facing away from the opening.

[0009] In one possible implementation, the water heater shell structure provided in the present application, the fixed bracket includes a support column and at least three support arms arranged on the support column, the support column extends coaxially along the axial direction of the shell, the support arms extend radially along the support column, and each support arm is evenly arranged around the circumference of the support column.

[0010] In a possible implementation, in the water heater shell structure provided by the present application, one end of the support arm facing away from the support column abuts against the circumferential inner wall of the shell.

[0011] In a possible implementation, the water heater housing structure provided by the present application, the support arm includes at least two vertical plates, and the vertical plates are spaced apart along the axial direction of the support column;

[0012] The sides of the vertical boards facing away from the support column are connected to each other, and / or the sides of the vertical boards facing away from the opening are connected to each other.

[0013] In a possible implementation, the water heater shell structure provided in the present application has a feed port provided on the vertical plate.

[0014] In one possible implementation, the water heater housing structure provided by the present application has a support column that is an annular column, and an extension plate extending radially thereof is provided at one end of the support column facing away from the outlet, and the extension plate is connected to the support arm;

[0015] Reinforcement ribs are provided between the extension plate and the support column.

[0016] In a possible implementation, in the water heater shell structure provided in the present application, a transition fillet is provided at an edge of an end surface of the shell facing away from the outlet.

[0017] On the other hand, the present application provides an electric water heater, comprising an inner tank and any of the above-mentioned water heater shell structures, wherein the inner tank is arranged in the water heater shell structure.

[0018] In one possible implementation, the electric water heater provided in the present application further includes a bracket assembly and a water pipe assembly. The shell of the water heater shell structure is circumferentially provided with a first mounting hole and a second mounting hole. The bracket assembly is threadedly connected to the inner tank and the shell through the first mounting hole, and the water pipe assembly is plugged into the inner tank and the shell through the second mounting hole.

[0019] The water heater shell structure and electric water heater provided by the present application are characterized by providing a shell with an open end, a fixing bracket, and an end cover. The end of the shell facing away from the opening is a closed structure. The fixing bracket abuts against the end of the shell facing away from the opening, and the fixing bracket is used to abut against the inner tank to provide support for the inner tank. The opening is sealed by the end cover, and the end cover is used to abut against the end of the inner tank facing the opening, thereby fixing the inner tank between the shell and the end cover and placing the inner tank in the housing cavity of the shell. In this way, when assembling the electric water heater, only one end cover needs to be provided at the open end cover to achieve the closure of the housing cavity, simplifying the assembly of the electric water heater and improving assembly efficiency. And because the fixing bracket only abuts between the closed end of the shell and the end of the inner tank, and no fasteners are used to fix the fixing bracket, compared with the prior art in which an end cover with a support structure is provided on the side corresponding to the closed end of the shell, the fixing bracket can be separated from the closed end of the shell. Therefore, when the specifications of the inner tank are adjusted, the size of the fixing bracket can be flexibly replaced or adjusted to match the inner tank without adjusting the size of the end cover and the shell, making the water heater bracket structure more flexible and improving its applicability.

[0035] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The terms "first," "second," "third," "fourth," and so on (if any) in the specification and claims of this application and the drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0038] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0039] In the prior art, electric water heaters typically include a cylindrical housing with openings at both ends. Therefore, corresponding end caps are required at each end of the openings to seal the housing's openings. An inner liner is also located within the housing's accommodating cavity. To ensure the inner liner's relative position within the housing is stable, at least one end cap is also provided with a support structure that mates with the inner liner's end structure. The support structure is typically formed directly on the end cap, or a foam padding is provided that mates with the inner liner's end. The support structure or foam padding ensures the inner liner is stably supported within the space enclosed by the housing and the end caps.

[0040] Therefore, when assembling an electric water heater, it is usually necessary to first assemble one of the end covers on the shell, then hoist the inner tank into the shell and position it against the support structure on the end cover, then flip the whole thing over and install other accessories, such as the bracket assembly and water pipe assembly, and then install the other end cover. Therefore, two end cover installation operations are required.

[0041] Because the support structure is pre-installed on the end cap, the end cap needs to be compatible with the specifications of the inner liner, and thus the shell needs to be compatible with the end cap. When the size of the inner liner needs to be adjusted, the entire structure of the end cap needs to be adjusted simultaneously to make the support structure compatible with the inner liner, and even the size of the shell needs to be adjusted.

[0042] This shows that the flexibility of the electric water heater assembly structure is low and the operation is complicated.

[0043] In order to solve the above problems, the present application provides an electric water heater, which simplifies the assembly structure of the electric water heater by providing a shell with an open end and a closed end, and providing an independent fixing bracket to abut the closed end of the shell. The size of the fixing bracket can be flexibly adjusted according to the specifications of the inner tank without changing the shell and the end cover at the opening. During assembly, only the end cover needs to be installed at the open end, thereby improving the flexibility of the assembly structure of the electric water heater and simplifying its assembly operation.

[0044] The electric water heater provided in this application will be described in detail below with reference to the accompanying drawings.

[0045] Figure 1 A schematic diagram of the structure of the electric water heater provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the connection between the shell structure and the inner tank of the water heater; Figure 3 for Figure 2 Middle AA section view.

[0046] On the one hand, the present application provides an embodiment of a water heater bracket, such as Figures 1 to 3 As shown, the water heater housing structure provided in the present application includes a housing 100, a fixing bracket 200 and an end cover 400. The housing 100 has a receiving cavity 130. One end of the housing 100 has an opening 120 communicating with the receiving cavity 130. The receiving cavity 130 is used to receive the inner tank 300 of the water heater.

[0047] The fixing bracket 200 is located in the accommodating cavity 130 and is used to abut between the inner liner 300 and the end of the shell 100 facing away from the opening 120 . The end cover 400 covers the opening 120 and is used to abut against the inner liner 300 .

[0048] It is understood that the shell 100 of the water heater shell structure of the present application is provided with an opening 120 at only one end. Therefore, the other end of the shell 100 facing away from the opening 120 can be considered a closed end 110, and the closed end 110 is integrally connected to the circumferential surface of the shell 100. In a specific implementation, the shell 100 can be processed through an integrated molding process such as integrated stretch molding or integrated injection molding. The integrated molding process refers to the process of molding the entire component in a single mold at one time. Compared with traditional step-by-step manufacturing processes, integrated molding can simplify the manufacturing process, and has high precision and production efficiency, and low production costs.

[0049] In this way, by setting up a shell 100 structure with one end closed, the number of required end covers 400 can be reduced, so that only an end cover 400 needs to be set at one end of the opening 120 of the shell 100 to close the accommodating cavity 130 in the shell 100. Therefore, during assembly, only one assembly operation of the end cover 400 needs to be performed, which simplifies the assembly of the electric water heater and improves the assembly efficiency.

[0050] An electrical room structure may be provided on the end cover 400 , and electrical components may be assembled in the electrical room to control the operation of the electric water heater. In addition, a maintenance cover for sealing the electrical room is also provided on the outer side of the end cover.

[0051] Furthermore, the present application provides an independent fixing bracket 200 at the closed end 110 of the housing 100. The fixing bracket 200 does not need to be fixedly connected to either the inner liner 300 or the housing 100. It only needs to abut against the inner liner 300 and the closed end 110 of the housing 100 to effectively prevent the inner liner 300 and the closed end 110 of the housing 100 from approaching each other. Furthermore, the fixing bracket 200 can provide support for the inner liner 300 and the closed end 110, thereby reducing the pressure exerted by the inner liner 300 on the fixed end and making the water heater housing structure more stable and reliable.

[0052] When the specifications and dimensions of the inner tank 300 need to be adjusted, and if the volume of the accommodating cavity 130 allows, the structural dimensions of the shell 100 and the end cover 400 are kept unchanged, and only the fixing bracket 200 needs to be adaptively adjusted. There is no need to redesign the end cover 400 mold and the shell 100 mold with a supporting structure that are compatible with the inner tank 300, which makes the assembly of the electric water heater more flexible, improves its overall applicability, and reduces the production cost of the electric water heater.

[0053] Therefore, the water heater shell structure provided by the present application is provided with a shell 100 with an opening 120 at one end, a fixing bracket 200 and an end cover 400. The end of the shell 100 facing away from the opening 120 is a closed end 110. The fixing bracket 200 is located between the closed end 110 of the shell 100 and the end of the inner tank 300, and abuts against both of them, so that the inner tank 300 is located in the accommodating cavity 130 of the shell 100. In this way, only one end cover 400 is required to be provided at the end cover of the opening 120 to achieve the closure of the accommodating cavity 130, simplifying the assembly of the electric water heater and improving assembly efficiency. Moreover, when the specifications of the inner tank 300 are adjusted, the size of the fixing bracket 200 can be flexibly replaced or adjusted to match the inner tank 300, making the assembly of the electric water heater more flexible and improving its applicability.

[0054] Thus, in some embodiments, as Figure 2 As shown, the end of the fixing bracket 200 facing the opening 120 is configured to adapt to the arc surface of the end of the inner liner 300, and the end of the fixing bracket 200 facing away from the opening 120 abuts against the end surface of the shell 100 facing away from the opening 120.

[0055] It can be understood that since the inner tank 300 and the shell 100 are fixedly connected, the spacing between the inner tank 300 and the closed end 110 is ensured. After the electric water heater is assembled, the inner tank 300 and the shell 100 can reversely clamp the fixing bracket 200 to ensure that the position of the fixing bracket 200 is fixed, so as to improve the stability and reliability of the overall structure of the electric water heater, and eliminate the need for fasteners, making its structure more compact.

[0056] Among them, the end of the fixing bracket 200 facing the inner liner 300 is adapted to the arc surface of the end of the inner liner 300 to ensure that the fixing bracket 200 stably supports and limits the inner liner 300, and it is convenient to improve the positioning and abutment effect between the inner liner 300 and the fixing bracket 200, and the end of the fixing bracket 200 facing the closed end 110 and the end face of the closed end 110 are set to be flat and abut against each other, so that the pressure of the inner liner 300 can be dispersed as evenly as possible on the end face of the closed end 110, so that the closed end 110 and the fixing bracket 200 can withstand a larger load, and avoid white deformation of the end face of the closed end 110, and avoid white marks on the appearance of the force-bearing part due to local large force.

[0057] Figure 4 for Figure 2 A schematic structural diagram of the middle fixing bracket 200; Figure 5 A schematic structural diagram of the fixing bracket and part of the inner tank of the water heater bracket provided in an embodiment of the present application.

[0058] In some embodiments, as Figure 4 and Figure 5As shown, the fixed bracket 200 includes a support column 210 and at least three support arms 220 arranged on the support column 210, the support column 210 extends coaxially along the axial direction of the shell 100, the support arms 220 extend radially along the support column 210, and each support arm 220 is evenly arranged around the circumference of the support column 210.

[0059] It can be understood that by coaxially extending the support column 210 along the axis of the shell 100, the fixed bracket 200 can form a support structure centered on the axis of the shell 100, so that the supporting force between the inner liner 300 and the fixed bracket 200 is more balanced and stable.

[0060] At least three support arms 220 are evenly arranged around the circumference of the support column 210 and extend radially along the radial direction of the support column 210. This facilitates the fixing bracket 200 to provide stable support for the inner liner 300 from the periphery of the inner liner 300, similar to a surface contact method, but with less consumables and a more compact structure. Specifically, in this embodiment, three support arms 220 are provided. In other embodiments, four or five or more support arms 220 may also be provided, and this application is not limited to this.

[0061] Figure 6 This is a schematic structural diagram of the fixed bracket and part of the shell of the water heater provided in an embodiment of the present application.

[0062] Furthermore, in this embodiment, Figure 6 As shown, the radial dimension of the fixing bracket 200 is smaller than the radial dimension of the circumferential inner wall of the housing 100 , so that the fixing bracket 200 is miniaturized and convenient for flexible installation.

[0063] However, since the radial dimension of the fixing bracket 200 is smaller than the inner diameter of the shell 100, when the inner liner 300 is not fixedly connected to the shell 100, the fixing bracket 200 will sometimes inevitably move relative to the end surface of the closed end 110. Therefore, in some embodiments, the end of the support arm 220 that is away from the support column 210 abuts against the circumferential inner wall of the shell 100.

[0064] It can be understood that such a setting is equivalent to extending the length of the support arm 220, so that the outer peripheral side of the fixing bracket 200 abuts against the inner peripheral side of the shell 100, and the fixing bracket 200 is limited by the inner peripheral side of the shell 100, thereby ensuring that the relative position of the fixing bracket 200 is stable without the need to set fasteners.

[0065] In specific implementation, such as Figures 4 to 6 As shown, the support arm 220 includes at least two vertical plates 221, and the vertical plates 221 are spaced apart along the axial direction of the support column 210;

[0066] The sides of the vertical plates 221 facing away from the support column 210 are connected to each other, and / or the sides of the vertical plates 221 facing away from the opening 120 are connected to each other.

[0067] It can be understood that by forming the support arm 220 with at least two closely arranged vertical plates 221, a cavity can be formed in the support arm 220, which is convenient for filling with more foaming material to ensure the thermal insulation performance of the electric water heater.

[0068] In addition, the vertical plates 221 are arranged at axial intervals along the support column 210. When the support arm 220 abuts against the inner liner 300, the line contact form of the edge of the vertical plate 221 can be converted into a similar surface contact form formed by multiple vertical plates 221, which is beneficial to improving the supporting capacity of the support arm 220 and reducing the contact area between the support arm 220 and the inner liner 300, thereby reducing the heat transfer of the inner liner 300.

[0069] By connecting the side of the vertical plate 221 facing away from the support column 210 and the side facing the vertical plate 221 to each other, the stability of the vertical plate 221 itself can be further improved, so that the vertical plates 221 on each support arm 220 form a whole, avoiding the breakage and damage of a single vertical plate 221 due to being unable to withstand the pressure of the inner liner 300.

[0070] In this embodiment, three vertical plates 221 are set in each support arm 220, and the middle vertical plate 221 can serve as a reinforcing rib plate of the support arm 220, which can further ensure the structural stability of the support arm 220 and improve the supporting capacity of the support arm 220.

[0071] In addition, if Figure 4 As shown, a feed port 222 is provided on the vertical plate 221 .

[0072] With such a configuration, when the foam material is filled later, the foam material can flow from the material outlet 222, reducing the obstruction of the fixed bracket 200 to the flow of the foam material, improving the filling efficiency of the foam material, and further improving the thermal insulation effect of the electric water heater.

[0073] In this embodiment, the feed port 222 is a slot opened on the side of the vertical plate 221 facing the inner liner 300, while in other embodiments, the feed port 222 can also be a slot opened on the side of the vertical plate 221 away from the support column 210 or a slot facing the closed end 110, and this application does not impose any restrictions on this.

[0074] And, as Figures 4 to 6 As shown, the support column 210 is an annular column, and an end of the support column 210 facing away from the opening 120 is provided with an extension plate 211 extending along its radial direction, and the extension plate 211 is connected to the support arm 220;

[0075] A reinforcing rib 212 is provided between the extension plate 211 and the support column 210 .

[0076] It can be understood that setting the support column 210 as a hollow annular column can further lightweight the structure of the fixed bracket 200 and reduce the contact area between the fixed bracket 200 and the inner tank 300, thereby reducing the heat exchange efficiency between the fixed bracket 200 and the inner tank 300, thereby improving the thermal insulation performance of the electric water heater.

[0077] An extension plate 211 is provided between the support column 210 and the support arm 220 to abut the closed end 110, and reinforcing ribs 212 are provided on the extension plate 211 and the support column 210 bracket. This can further expand the contact area between the fixed bracket 200 and the closed end 110, reduce the pressure of the fixed bracket 200 on the closed end 110, and improve the overall structural stability of the fixed bracket 200 through the reinforcing ribs 212.

[0078] In some embodiments, a transition fillet 111 is provided on an edge of an end surface of the housing 100 facing away from the opening 120 .

[0079] Such an arrangement facilitates the molding of the housing 100 during the processing, reduces structural cracking, improves the structural strength of the housing 100, and makes the overall appearance of the electric water heater more beautiful.

[0080] On the other hand, Figure 2 As shown, the present application provides an embodiment of an electric water heater, comprising an inner tank 300 and a water heater shell structure in any of the above embodiments, wherein the inner tank 300 is disposed in the water heater shell structure.

[0081] The shell structure of the water heater has been described in detail in the above embodiments, and will not be described again in detail.

[0082] Further, if Figures 1 to 3 As shown, the electric water heater provided in this application also includes a bracket assembly 500 , and a first mounting hole 140 is provided circumferentially on the shell 100 of the water heater shell structure, and the bracket assembly 500 is threadedly connected to the inner tank 300 and the shell 100 through the first mounting hole 140 .

[0083] The electric water heater can be stably mounted on the wall by means of the bracket assembly 500. It is understood that by providing the first mounting hole 140 in the housing 100 and installing the bracket assembly 500 on the inner liner 300 and the housing 100 through the first mounting hole 140, a fixed connection between the housing 100 and the inner liner 300 can be achieved, thereby limiting relative displacement between the inner liner 300 and the housing 100.

[0084] Specifically, the bracket assembly 500 includes an external wall bracket 510 and an inner liner bracket 520, wherein the external wall bracket 510 is located on the outside of the shell 100, and the inner liner bracket 520 is located on the inside of the shell 100. In this way, the shell 100 can be clamped between the external wall bracket 510 and the inner liner bracket 520 by passing bolts through the external wall bracket 510, the shell 100 and the inner liner bracket 520 in sequence, and the inner liner 300 and the inner liner bracket 520 are fixedly connected by bolts or welded, thereby achieving a fixed connection between the inner liner 300 and the shell 100.

[0085] At the same time, Figures 1 to 3 As shown, the electric water heater provided in the present application also includes a water pipe assembly 600 (not fully shown), and a second mounting hole 150 is provided in the circumference of the shell 100 of the water heater shell structure, and the water pipe assembly 600 is plugged into the inner tank 300 and the shell 100 through the second mounting hole 150.

[0086] The water pipe assembly 600 can connect the electric water heater to the water pipe to achieve water inlet and outlet of the electric water heater. It can be understood that by providing the second mounting hole 150 on the housing 100 and providing the water pipe assembly 600, the stability of the fixed connection between the housing 100 and the inner liner 300 can be further strengthened, ensuring that the relative position between the inner liner 300 and the housing 100 is stable and reliable.

[0087] Therefore, when assembling the electric water heater, the inner container 300 can be placed vertically on the tooling and fixed, and then the fixing bracket 200 can be placed on the end cap of the inner container 300 so that the fixing bracket 200 abuts against the end of the inner container 300. Then, the housing 100 with the opening 120 facing downward is placed over the inner container 300 and the fixing bracket 200 so that the fixing bracket 200 abuts against the closed end 110, and the fixing bracket 200 maintains the distance between the inner container 300 and the closed end 110. The entire assembly is then turned over so that the inner container 300 is pressed tightly against the fixing bracket 200, and the fixing bracket 200 disperses the pressure exerted by the inner container 300 on the closed end 110. Afterwards, other structural components of the electric water heater, such as the hanger assembly 500 and the water pipe assembly 600, can be installed, and the inner liner 300 and the shell 100 can be fixedly connected by the hanger assembly 500 and the water pipe assembly 600. After the inner liner 300 and the shell 100 are fixedly connected, the fixing bracket 200 is clamped between the inner liner 300 and the shell 100 bracket and will not move easily, which indirectly ensures the relative position stability of the fixing bracket 200 without the need to set fasteners to connect the fixing bracket 200 to either the inner liner 300 or the shell 100. After completing the above assembly operations, the end cover 400 can be installed and the foaming material can be injected from the injection port on the end cover 400. Through the filling and curing of the foaming material, the relative position of the fixing bracket 200 can be further stabilized, ensuring the stability and compactness of the overall structure of the electric water heater.

[0088] It should be noted here that if the assembly operating environment of the electric water heater has the conditions for hoisting, the opening 120 of the shell 100 can be fixed upward on the tooling, and the fixing bracket 200 can be placed in the shell 100, and then the inner tank 300 can be hoisted into the shell 100, and then the hanging bracket assembly 500 and the water pipe assembly 600 can be installed, and finally the end cover 400 can be directly covered and the foam material can be injected, thereby eliminating the flipping operation in the assembly of the electric water heater and further simplifying its assembly.

[0089] In summary, the water heater bracket and electric water heater provided in the present application, the water heater bracket is provided with a shell 100 with an opening 120 at one end, a fixed bracket 200 and an end cover 400, the end of the shell 100 facing away from the opening 120 is a closed structure, the fixed bracket 200 is abutted against the end of the shell 100 facing away from the opening 120, and the fixed bracket 200 is used to abut against the inner tank 300 to provide support for the inner tank 300, the opening 120 is sealed by the end cover 400, and the end cover 400 is used to abut against the end of the inner tank 300 facing the opening 120, thereby fixing the inner tank 300 between the shell 100 and the end cover 400, and placing the inner tank 300 in the accommodating cavity 130.

[0090] Thus, when assembling the electric water heater, only an end cap 400 needs to be installed on the opening 120 to achieve the closure of the accommodating chamber 130, thereby simplifying the assembly structure of the electric water heater and improving assembly efficiency. In addition, since the fixing bracket 200 only abuts between the closed end 110 of the shell 100 and the end of the inner tank 300, and no fasteners are used to fix the fixing bracket 200, compared with the prior art in which an end cap 400 with a support structure is provided on the side of the shell 100 corresponding to the closed end 110, the fixing bracket 200 can be separated from the closed end 110 of the shell 100. Therefore, when the specifications of the inner tank 300 are adjusted, the size of the fixing bracket 200 can be flexibly replaced or adjusted to match the inner tank 300 without adjusting the size of the end cap 400 and the shell 100, making the assembly structure of the electric water heater more flexible and improving its applicability.
