Description

Technical Field

[0001] This utility model belongs to the field of electric water heater technology, and in particular relates to a tank assembly for an electric water heater and an electric water heater. Background Technology

[0002] Currently, water heaters are common household appliances, categorized into gas water heaters, electric water heaters, heat pump water heaters, and solar water heaters. Electric water heaters are widely used due to their convenience. Electric water heaters can be further classified by heating power into storage-type and instantaneous types. Storage-type water heaters, equipped with a water tank, offer advantages such as large water output and stable water temperature, making them more popular among families. Electric water heaters require wall mounting, typically using an external wall bracket. Since both the inner and outer tanks are usually made of metal, the direct metal connection between them causes heat to escape from the inner tank along the bracket, negatively impacting the water heater's heat retention.

[0003] A Chinese patent with publication number CN220303906U discloses an external wall mount, comprising: a mounting bracket for fixing on the outer tank of a water heater; a pad, disposed on the mounting bracket and located between the outer and inner tanks of the water heater, the pad being a heat-insulating block made of heat-insulating material; the pad comprising: a pad plate for connecting to the mounting bracket; and a frame disposed on the side of the pad plate facing the outer wall of the inner tank of the water heater, the side of the frame facing away from the pad plate for abutting against the outer wall of the inner tank of the water heater.

[0004] The aforementioned water heater improves its insulation by using a spacer on the mounting bracket between the outer and inner tanks. This spacer prevents heat transfer from the inner tank to the outer tank, thus enhancing the water heater's heat retention. However, this requires additional spacers, increasing both manufacturing costs and installation complexity. Therefore, the technical problem this invention aims to solve is to design an electric water heater that reduces heat transfer from the inner tank to the outer tank via the mounting bracket, while also lowering costs and simplifying installation. Utility Model Content

[0005] This utility model provides a tank assembly for an electric water heater and an electric water heater, which reduces the amount of heat transferred from the inner tank to the outer tank through the bracket, while also reducing costs and simplifying installation.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In the first aspect, this utility model provides a tank assembly for an electric water heater, comprising:

[0008] shell;

[0009] The inner liner is disposed within the outer shell;

[0010] An inner liner support is located between the inner liner and the outer shell, with one end of the inner liner support connected to the inner liner and the other end of the inner liner support abutting against the inner wall surface of the outer shell.

[0011] A housing support frame is disposed on the outer wall surface of the housing;

[0012] A first fastener, configured to connect the inner liner support and the outer shell support to the outer shell;

[0013] The outer shell is made of plastic material.

[0014] In some embodiments of this application, one end of the inner liner support has two ear plates, which are respectively fixedly connected to the inner liner. A bent portion protruding outward relative to the inner liner is formed between the two ear plates of the inner liner support, and the bent portion abuts against the inner wall surface of the outer shell.

[0015] By setting two ear plates at one end of the inner liner support, and fixing the two ear plates to the inner liner respectively, the inner liner support is fixed to the inner liner. A bent part protruding outward relative to the inner liner is formed between the two ear plates. The bent part abuts against the inner wall surface of the outer shell, thereby limiting the distance between the inner liner and the outer shell, preventing the inner liner and the outer shell from sticking together, and improving the heat preservation effect.

[0016] In some embodiments of this application, the outer casing bracket has a first mounting hole, the outer casing has a second mounting hole, the bent portion has a threaded hole, and the first fastener passes through the first mounting hole and the second mounting hole and is threadedly connected to the threaded hole.

[0017] By opening a first mounting hole on the outer shell bracket, a second mounting hole on the outer shell, and a threaded hole on the bent part, the first fastener passes through the outer shell bracket and is threadedly connected to the inner liner bracket. The structure is simple, the connection is reliable, and it is easy to assemble and disassemble.

[0018] In some embodiments of this application, the housing support includes:

[0019] A first support portion, which abuts against the outer wall surface of the outer shell, and the first support portion is provided with the first mounting hole;

[0020] The second support part has one end connected to the first support part and the other end spaced apart from the outer casing. The second support part has a fixing hole configured for a wall hook to pass through in order to fix the electric water heater to the wall.

[0021] By including a first support part and a second support part in the outer casing bracket, the first support part is close to the outer wall surface of the outer casing, and the contact area between the first support part and the outer casing is large, which improves the stability of the connection between the outer casing bracket and the outer casing; the second support part is connected to the first support part, and there is a gap between the other end of the second support part and the outer casing, so that the wall hook can pass through the fixing hole on the second support part, thereby realizing the wall fixing of the electric water heater.

[0022] In some embodiments of this application, the tank assembly for an electric water heater further includes:

[0023] The second fastener has a limiting hole on the first support portion, which is configured to allow the second fastener to pass through in order to fix the housing bracket to the housing.

[0024] When the outer shell bracket, outer shell, and inner liner bracket are only fixedly connected by the first fastener, the outer shell bracket is prone to rotation when subjected to external force. By opening a limiting hole on the first support part and passing the second fastener through the limiting hole to fix the outer shell bracket to the outer shell, the outer shell bracket can be fixed to the outer shell by two fasteners, thus preventing the outer shell bracket from rotating.

[0025] In some embodiments of this application, the housing support further includes:

[0026] A third support portion, wherein the third support portion is connected between the first support portion and the second support portion; and / or,

[0027] A fourth support portion is connected between the first support portion and the second support portion and is arranged opposite to the third support portion.

[0028] By setting a third support and / or a fourth support, it is beneficial to strengthen the connection between the first support and the second support.

[0029] In some embodiments of this application, the tank assembly for an electric water heater further includes:

[0030] A support pad is disposed on the housing and located below the housing support, the support pad being configured to provide support between the housing and the wall when the electric water heater is fixed to the wall.

[0031] By installing support pads on the outer casing, which are located below the casing bracket, the support pads can support the outer casing and prevent it from sliding back after the electric water heater is hung on the wall. In this way, the support pads and the casing bracket can provide support for the installation of the electric water heater on the wall.

[0032] In some embodiments of this application, the outer end face of the support pad and the outer end face of the outer shell bracket are in the same plane.

[0033] By setting the outer end face of the support pad and the outer end of the outer casing bracket in the same plane, the stability of the electric water heater installation can be improved, and deformation of the outer casing bracket can be prevented.

[0034] In some embodiments of this application, the support pad and the outer shell are an integral structure.

[0035] By integrating the support pad with the outer casing into a single structure, the design is simple and eliminates the need for additional molds to manufacture the support pad. This improves production efficiency, reduces costs, and enhances the stability and reliability of electric water heater installation.

[0036] In some embodiments of this application, the outer casing is provided with an opening, and the tank assembly for the electric water heater further includes:

[0037] An anti-electric shock wall cover is provided at the opening and located on the outside of the outer shell;

[0038] A stop member is disposed at the opening and located inside the housing, the stop member being configured to prevent foam material in the housing from entering the anti-electric shock wall cover;

[0039] The outer shell and the anti-electric shock wall cover are integrally molded structures.

[0040] By setting an opening on the outer shell, the anti-electric shock wall cover is set at the opening and located on the outside of the outer shell. The outer shell and the anti-electric shock wall cover are integrally molded structures, and the anti-electric shock wall cover does not need to be manufactured separately, which helps to reduce production costs. By setting a stop at the opening, the stop can prevent the foam material in the outer shell from entering the anti-electric shock wall cover, thus avoiding any impact on the components inside the anti-electric shock wall cover.

[0041] In a second aspect, the present invention provides an electric water heater, including a tank assembly for an electric water heater as described in any one of the embodiments of the first aspect above.

[0042] Compared with the prior art, the advantages and positive effects of this utility model are as follows: The tank assembly for an electric water heater includes an outer shell, an inner tank, an inner tank support, an outer shell support, and a first fastener. The inner tank is disposed within the outer shell, and the inner tank support is located between the inner tank and the outer shell. One end of the inner tank support is fixedly connected to the inner tank, and the other end abuts against the inner wall surface of the outer shell, thus separating the inner tank and the outer shell. The first fastener connects the inner tank support and the outer shell support to the outer shell, achieving a fixed connection between the outer shell support, the outer shell, the inner tank support, and the inner tank. The outer shell support is disposed on the outer wall surface of the outer shell, allowing the electric water heater to be fixed to the wall via the outer shell support. The outer shell is made of plastic material, which inherently has good heat insulation properties, thus eliminating the need for the heat insulation pad component in the prior art, reducing production costs, and simplifying installation.

[0073] An electric water heater is a type of water heater that uses electricity as its primary energy source. The high-temperature heat generated after the power is turned on directly heats the water stored in the water heater to produce hot water.

[0074] Electric water heaters typically consist of a water tank, an electric heating element, and an electronic control board. The water tank has a storage cavity to store water to be heated. The electric heating element is inserted into the storage cavity of the water tank. The electronic control board is used to control the electric heating element to operate by turning the power on and off, so that the water in the tank is heated to the set temperature.

[0075] For the water tank of an electric water heater, the tank generally consists of an outer shell and an inner tank, with an insulation layer between them. The outer shell is usually made of plastic to meet the requirements of aesthetic and diverse designs; the inner tank can be made of metal or plastic, depending on the needs.

[0076] In addition, the insulation layer formed between the outer shell and the inner liner is commonly made of materials such as asbestos, sponge, foam plastic, and polyurethane foam. In conventional technology, foaming is usually used to form the insulation layer in order to achieve good insulation effect.

[0077] For water tanks with metal inner liner, corrosion can easily occur inside due to water quality. Therefore, magnesium rods are installed on the water tank and inserted into the water storage cavity inside the tank.

[0078] Magnesium has the lowest electrochemical potential among metals and is physiologically non-toxic. Therefore, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod directly affects the duration and effectiveness of the protection; the larger the magnesium rod, the better the protection and the longer the protection time.

[0079] The water tank is also equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to deliver cold water into the water storage cavity formed inside the water tank, while the hot water in the water storage cavity is output from the outlet pipe.

[0080] For electric heating components, electric heating methods such as electric heating wires, magnetic energy, or silicon tube heating can be used to heat the water stored in the water storage chamber.

[0081] The control board is used to receive detection signals from relevant sensors (such as water temperature sensors and flow sensors) and control the power supply to and from the electric heating components.

[0082] When the electric water heater is working, the electric control board controls the electric heating element to be powered on and heated. When the water temperature in the tank reaches the set value, the electric control board controls the electric heating element to be powered off.

[0083] In the first aspect, combining Figures 1 to 12 As shown, this disclosure provides a tank assembly for an electric water heater, which includes an outer shell 1, an inner tank 2, an inner tank support 3, an outer shell support 4, and a first fastener 5.

[0084] The inner liner 2 is set in the outer shell 1, and the inner liner 2 and the outer shell 1 enclose and form an installation cavity. The inner liner 2 is made of metal material.

[0085] The inner liner support 3 is located in the installation cavity between the inner liner 2 and the outer shell 1. One end of the inner liner support 3 is fixed to the outer wall of the inner liner 2 by welding, and the other end of the inner liner support 3 abuts against the inner wall of the outer shell 1.

[0086] Combination Figure 2 As shown, the housing bracket 4 is disposed on the outer wall surface of the housing 1, and the housing bracket 4 is configured to fix the electric water heater to the wall.

[0087] The first fastener 5 is configured to connect the inner liner bracket 3 and the outer shell bracket 4 to the outer shell 1.

[0088] Specifically, the first fastener 5 includes a bolt.

[0089] During installation, a rubber pad is fitted on the bolt shank near the bolt head. The rubber pad increases the contact area and reduces pressure; it also reduces bolt vibration and loosening, and improves the bolt fixing effect; at the same time, the rubber pad plays a role in filling and sealing between the bolt and the outer casing bracket 4.

[0090] The outer shell 1 is made of plastic material and is processed by blow molding.

[0091] Specifically, by making the outer casing 1 with a plastic material, which has low thermal conductivity and does not easily transfer heat, the heat is retained in the outer casing 1.

[0092] Specifically, by placing the inner tank support 3 between the inner tank 2 and the outer shell 1, with one end of the inner tank support 3 fixedly connected to the inner tank 2 and the other end abutting against the inner wall surface of the outer shell 1, the inner tank support 3 separates the inner tank 2 and the outer shell 1, reducing heat transfer; the first fastener 5 connects the inner tank support 3 and the outer shell support 4 to the outer shell 1, achieving a fixed connection between the outer shell support 4, the outer shell 1, the inner tank support 3, and the inner tank 2; the outer shell support 4 is placed on the outer wall surface of the outer shell 1, and the electric water heater can be fixed to the wall through the outer shell support 4. The outer shell 1 is made of plastic material. Since the plastic material of the outer shell 1 itself has good heat insulation effect, the heat insulation pad component in the prior art is eliminated, which helps to reduce production costs and simplify installation.

[0093] In some embodiments of this application, the inner liner support 3 is U-shaped or C-shaped. It is understood that the shape of the inner liner support 3 includes, but is not limited to, the above-described structural forms.

[0094] In some other embodiments of this application, one end of the inner liner support 3 has two ear plates 31, which are fixedly connected to the inner liner 2 respectively. A bent portion 32 protruding outward relative to the inner liner 2 is formed between the two ear plates 31 of the inner liner support 3, and the bent portion 32 abuts against the inner wall surface of the outer shell 1.

[0095] Specifically, the inner tube support 3 can be obtained by bending sheet metal parts.

[0096] Specifically, the two ear plates 31 are fixed to the inner liner 2 by welding, so that the two ear plates 31 are tightly fitted to the outer wall of the inner liner 2. A bent portion 32 protruding outward relative to the inner liner 2 is formed between the two ear plates 31. The bent portion 32 is connected to the ear plates 31 and abuts against the inner wall of the outer shell 1, thereby limiting the distance between the inner liner 2 and the outer shell 1, preventing the inner liner 2 and the outer shell 1 from sticking together, and improving the heat preservation effect.

[0097] In some embodiments of this application, combined with Figure 3 and Figure 4 As shown, the outer casing bracket 4 has a first mounting hole 411, the outer casing 1 has a second mounting hole 11, the bent part 32 has a threaded hole 321, and the first fastener 5 passes through the first mounting hole 411 and the second mounting hole 11 and is threadedly connected to the threaded hole 321.

[0098] Specifically, the first mounting hole 411, the second mounting hole 11, and the threaded hole 321 correspond to each other, so that the first fastener 5 passes through the outer shell bracket 4, the outer shell 1, and the inner liner bracket 3 in sequence and is threadedly connected. The structure is simple, the connection is reliable, and it is convenient to disassemble and assemble.

[0099] Specifically, in combination Figure 5 , Figure 6 and Figure 7 As shown, a protrusion 322 is formed on the surface of the bent portion 32 facing the inner liner 2. The protrusion 322 corresponds to the position of the threaded hole 321. The protrusion 322 extends the depth of the threaded hole 321, which helps to improve the reliability of the connection between the first fastener 5 and the bent portion 32.

[0100] In some embodiments of this application, the housing support 4 includes a first support portion 41 and a second support portion 42.

[0101] The first support part 41 is in contact with the outer wall surface of the outer shell 1, and the first support part 41 is provided with a first mounting hole 411.

[0102] One end of the second support part 42 is connected to the first support part 41, and the other end is spaced from the outer casing 1. The second support part 42 is provided with a fixing hole 421, which is configured to allow a hook on the wall to pass through so as to fix the electric water heater to the wall.

[0103] Specifically, by including a first support part 41 and a second support part 42 in the outer casing bracket 4, the first support part 41 is close to the outer wall surface of the outer casing 1, and the contact area between the first support part 41 and the outer casing 1 is large, which improves the stability of the connection between the outer casing bracket 4 and the outer casing 1; the second support part 42 is connected to the first support part 41, and there is a gap between the other end of the second support part 42 and the outer casing 1, so that the wall hook can pass through the fixing hole 421 on the second support part 42, thereby realizing the wall fixing of the electric water heater.

[0104] In some embodiments of this application, the tank assembly for an electric water heater further includes a second fastener 6.

[0105] The first support portion 41 also has a limiting hole 412, which is configured to allow the second fastener 6 to pass through in order to fix the housing bracket 4 to the housing 1.

[0106] Specifically, when the outer shell bracket 4, the outer shell 1, and the inner liner bracket 3 are fixedly connected only by the first fastener 5, the outer shell bracket 4 is prone to rotation when subjected to external force. By opening a limiting hole 412 on the first support part 41, the second fastener 6 passes through the limiting hole 412 to fix the outer shell bracket 4 to the outer shell 1. In this way, the outer shell bracket 4 is fixed to the outer shell 1 by two fasteners, which can prevent the outer shell bracket 4 from rotating.

[0107] In some embodiments of this application, the housing support 4 further includes a third support portion 43 and / or a fourth support portion 44.

[0108] The third support part 43 is connected between the first support part 41 and the second support part 42, and the fourth support part 44 is connected between the first support part 41 and the second support part 42 and is arranged opposite to the third support part 43.

[0109] Specifically, by providing a third support portion 43 and / or a fourth support portion 44, it is beneficial to strengthen the connection between the first support portion 41 and the second support portion 42.

[0110] In other embodiments, the first support portion 41, the second support portion 42, the third support portion 43 and the fourth support portion 44 surround to form a receiving groove 45, and the head of the first fastener 5 is located in the receiving groove 45, so as to avoid the first fastener 5 interfering with the installation of the housing bracket 4.

[0111] Specifically, the edges of the first support part 41, the second support part 42, the third support part 43, and the fourth support part 44 are all on the outer end face of the outer shell bracket 4. During installation, the outer end face of the outer shell bracket 4 abuts against the wall.

[0112] In some embodiments of this application, combined with Figure 8 As shown, the tank assembly for an electric water heater also includes a support pad 7.

[0113] The support pad 7 is disposed on the housing 1 and located below the housing bracket 4. The support pad 7 is configured to provide support between the housing 1 and the wall when the electric water heater is fixed to the wall.

[0114] Specifically, when the electric water heater is hung on the wall, the support pad 7 can support the outer casing 1 and prevent the outer casing 1 from rolling back. In this way, the support pad 7 and the outer casing bracket 4 cooperate to provide support for the installation of the electric water heater on the wall.

[0115] In some embodiments of this application, the outer end face of the support pad 7 and the outer end face of the outer shell bracket 4 are in the same plane.

[0116] Specifically, by setting the outer end face of the support pad 7 and the outer end of the outer casing bracket 4 in the same plane, the stability of the electric water heater installation can be improved, and deformation of the outer casing bracket 4 can be prevented.

[0117] In some embodiments of this application, the support pad 7 and the outer shell 1 are an integral structure.

[0118] Specifically, by setting the support pad 7 and the outer shell 1 as an integrated structure, the structure is simple and there is no need to open a mold to manufacture the support pad 7. This can improve production efficiency, reduce costs, and enhance the stability and reliability of electric water heater installation.

[0119] In some embodiments, combined with Figure 9 As shown, the tank assembly for an electric water heater also includes a panel assembly 9.

[0120] The bottom of the outer casing 1 has a rectangular opening 12 on the user side. An anti-electric shock wall cover 13 is provided at the opening 12. The anti-electric shock wall cover 13 is located on the outside of the outer casing 1. An installation port 1311 is formed on the anti-electric shock wall cover 13. An accommodating cavity is formed inside the anti-electric shock wall cover 13. The installation port 1311 is connected to the accommodating cavity.

[0121] The panel assembly 9 includes a front panel 91 and a control panel 92. The front panel 91 is mounted on the anti-electric shock wall cover 13 and faces the user side. The control panel 92 is mounted on the front panel 91 and extends through the mounting port 1311 into the receiving cavity.

[0122] The outer shell 1 and the anti-electric shock wall cover 13 are integrally molded structures.

[0123] In this way, the anti-electric shock wall cover 13 does not need to be manufactured with a separate mold, which helps to reduce production costs; at the same time, the anti-electric shock wall cover 13 does not need to be installed, which simplifies the process, helps to improve production efficiency, and saves manpower.

[0124] In some embodiments, combined with Figure 11 , Figure 12 The anti-electric shock wall cover 13 shown includes a mounting plate 131, a back plate 132, and two side plates 133.

[0125] The mounting plate 131 faces the user side, extends downward from the upper edge of the opening 12, and has a mounting port 1311.

[0126] To facilitate user viewing of the front panel 91, the mounting plate 131 is at a certain angle to the vertical direction.

[0128] The upper ends of the two side plates 133 extend downward from the left and right edges of the opening 12, respectively, and are connected to the mounting plate 131 and the back plate 132, respectively. The mounting plate 131, the back plate 132 and the side plates 133 enclose and form a receiving cavity.

[0129] Specifically, by providing an installation port 1311 on the mounting plate 131, it is convenient to place the control panel 92 in the receiving cavity; the mounting plate 131, the back plate 132, and the side plate 133 are connected in pairs and integrally formed with the outer shell 1, which is convenient for processing and manufacturing, eliminates the assembly steps of the anti-electric wall cover 13, and helps to reduce costs and improve assembly efficiency.

[0130] In other embodiments, a plurality of slots 1312 are formed on the mounting plate 131, and a plurality of snap-fit ​​parts 911 are provided on the front panel 91, and the front panel 91 is snapped into the slots 1312 through the snap-fit ​​parts 911.

[0131] Specifically, the slot 1312 and the latching part 911 correspond one-to-one. By using the latching part 911 and the slot 1312 to cooperate, the front panel 91 and the mounting plate 131 can be assembled together, realizing screwless installation, which helps to improve assembly efficiency.

[0132] In addition, to improve the connection stability between the front panel 91 and the mounting plate 131, multiple slots 1312 are arranged around the mounting opening 1311 on the mounting plate 131.

[0133] The aforementioned front panel 91 is mainly slidably connected to the slot 1312 and the mounting plate 131 via the snap-fit ​​part 911. After the front panel 91 is installed in place, in order to prevent the front panel 91 from sliding relative to the mounting plate 131 and affecting its use, an auxiliary snap-fit ​​part 912 is also provided on the front panel 91. An auxiliary groove 1313 is provided on the mounting plate 131 at a position corresponding to the auxiliary snap-fit ​​part 912. In this way, after the snap-fit ​​part 911 of the front panel 91 is installed in the slot 1312, the corresponding auxiliary snap-fit ​​part 912 snaps into the auxiliary groove 1313, thus preventing the front panel 91 from sliding relative to the slot 1312.

[0134] In some embodiments of this application, multiple slots 1312 are all contracted in the same direction. This allows the latching portion 911 to engage more tightly with the slots 1312, preventing the front panel 91 from wobbling relative to the mounting plate 131 and improving the stability of the connection between the front panel 91 and the mounting plate 131.

[0135] In another embodiment, the latching portion 911 is a latching tongue extending to the left.

[0137] The rear cover plate 921 is mounted on the front panel 91. Specifically, the two ends of the rear cover plate 921 are provided with grooves (not shown), and the front panel 91 is provided with claws (not shown) at positions corresponding to the grooves. The claws are engaged in the grooves to connect the rear cover plate 921 and the front panel 91.

[0138] The circuit board 922 is fixed to the rear cover plate 921 by screws.

[0139] Specifically, by setting a rear cover plate 921, which is connected to the front panel 91, it is convenient to install the circuit board 922.

[0140] Specifically, circuit board 922 is equipped with a display screen and touch buttons as needed.

[0141] Correspondingly, the front panel 91 is provided with a touch area and a display area, with touch buttons arranged at the rear of the touch area and the display screen arranged at the rear of the display area.

[0142] In some embodiments of this application, combined with Figure 10 As shown, the tank assembly for an electric water heater also includes a left end cap 10 and a right end cap 20.

[0143] The left end cover 10 and the outer shell 1 are integrally formed, the right end cover 20 is detachably connected to the outer shell 1, and a maintenance cover 201 is provided on the right end cover 20.

[0144] Specifically, by setting the left end cover 10 and the outer shell 1 as an integral molding structure, there is no need to manufacture the left end cover 10 separately, which helps to save costs; the right end cover 20 is detachably connected to the outer shell 1, which facilitates the installation of the inner tank 2 of the electric water heater.

[0145] The right end cover 20 has an electrical mounting groove, which together with the maintenance cover 201 forms an electrical chamber (unmarked), and an electrical control board (unmarked) is installed in the electrical chamber. The electrical control board is electrically connected to the control panel 92 via a cable.

[0146] Specifically, to facilitate cable passage, a cable groove is provided on the rear cover plate 921, and a cable hole is provided on the right end cover 20.

[0147] In some embodiments of this application, the outer shell 1, the left end cover 10, the anti-electric shock wall cover 13, and the support pad 7 are integrally formed by blow molding.

[0148] For example, the outer casing 1, the left end cover 10, the anti-electric shock wall cover 13, and the support pad 7 are made of plastic, and the type of plastic used includes one or more combinations of ABS plastic, PVC plastic, or PC plastic.

[0149] In other embodiments, the outer casing 1 is shaped as a circle, an ellipse, a hexagon, or an octagon. It is understood that the shape of the outer casing 1 includes, but is not limited to, the types described above.

[0150] Specifically, this application has a simple structure, eliminating the need for separate mold manufacturing of the left end cover 10, the anti-electric wall cover 13, and the support pad 7. It also eliminates the step of assembling the left end cover 10, the anti-electric wall cover 13, and the support pad 7 with the outer shell 1, thereby improving production efficiency and reducing costs. The integrated structure enhances the stability and reliability of the electric water heater installation.

[0151] In some embodiments of this application, in order to integrate the outer shell 1 and the anti-electric wall cover 13 into one piece, and to facilitate the flow of material to fill the entire molding mold during the molding process of the outer shell 1, an opening 12 is provided on the outer shell 1 at a position corresponding to the anti-electric wall cover 13.

[0152] In the manufacturing process of electric water heaters, in order to improve the heat preservation effect, foaming material needs to be injected between the outer shell 1 and the inner tank 2. The foaming material will fill the cavity between the outer shell 1 and the inner tank 2. Since the outer shell 1 is provided with an opening 12, the foaming material will inevitably flow into the anti-electric wall cover 13 through the opening 12. The circuit board 922 in the anti-electric wall cover 13 is connected to the electrical control board in the electrical room through a cable. When the foaming material enters the anti-electric wall cover 13, it will affect the later maintenance cable.

[0153] Therefore, the tank assembly for the electric water heater also includes a stop 14, which is disposed at the opening 12 and located inside the housing 1. The stop 14 can block the opening 12 and prevent the foam material in the housing 1 from entering the receiving cavity of the anti-electric wall cover 13.

[0154] Specifically, the stop 14 is connected to the housing 1 by adhesive or fasteners.

[0155] Specifically, the stop 14 has an arc-shaped structure and matches the inner wall surface of the housing. Of course, the shape of the stop 14 includes, but is not limited to, the type described above.
