[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] In the first aspect, combining Figures 1 to 12 As shown, this utility model provides a tank assembly for an electric water heater, which includes a housing 1 and a panel assembly 9.

[0082] A rectangular opening 12 is provided at the bottom of the outer casing 1 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.

[0083] 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.

[0084] The outer shell 1 and the anti-electric wall cover 13 are integrally molded structures.

[0085] Specifically, by providing an opening 12 on the outer shell 1, and providing an anti-electric shock wall cover 13 at the opening 12, the outer shell 1 and the anti-electric shock wall cover 13 are integrally molded structures, and the anti-electric shock wall cover 13 does not need to be manufactured separately, which helps to reduce production costs; at the same time, the anti-electric shock wall cover 13 does not need to be assembled with the outer shell, simplifying the process, which helps to improve production efficiency and save manpower; the panel assembly 9 includes a front panel 91 and a control panel 92. The front panel 91 is set on the anti-electric shock wall cover 13 and faces the user side, and the control panel 92 is set on the front panel 91 and extends through the mounting opening 1311 into the receiving cavity, which facilitates assembly and user operation.

[0086] In some embodiments of this application, combined with Figure 3 , Figure 4 The anti-electric shock wall cover 13 shown includes a mounting plate 131, a back plate 132, and two side plates 133.

[0087] The mounting plate 131 faces the user side, extends downward from the upper edge of the opening 12, and has a mounting port 1311.

[0088] To facilitate user viewing of the front panel 91, the mounting plate 131 is at a certain angle to the vertical direction.

[0089] The back panel 132 is located behind the front panel 91. The back panel 132 extends downward from the lower edge of the opening 12, and the lower end of the back panel 132 is connected to the lower end of the mounting plate 131.

[0090] 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.

[0091] 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, and eliminates the assembly steps of the anti-electric wall cover 13 on the outer shell, which helps to reduce costs and improve assembly efficiency.

[0092] In some embodiments of this application, 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.

[0093] Specifically, multiple slots 1312 correspond one-to-one with multiple latching parts 911. By using the latching parts 911 and slots 1312 to cooperate, the front panel 91 and the mounting plate 131 can be assembled together, achieving screwless installation and improving assembly efficiency.

[0094] 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.

[0095] 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 mounting plate 1312.

[0096] 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.

[0097] In another embodiment, the latching portion 911 is a latching tongue extending to the left.

[0098] In some embodiments of this application, the control panel 92 includes a rear cover 921 and a circuit board 922.

[0099] 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.

[0100] The circuit board 922 is fixed to the rear cover plate 921 by screws.

[0101] 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.

[0102] Specifically, circuit board 922 is equipped with a display screen and touch buttons as needed.

[0103] 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.

[0104] In some embodiments of this application, combined with Figure 2 As shown, the tank assembly for an electric water heater also includes a left end cap 10 and a right end cap 20.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] Specifically, in order to facilitate the passage of cables, a cable groove is provided on the rear cover plate 921, and a cable hole is also provided on the right end cover 20.

[0109] In some embodiments of this application, the outer shell 1, the left end cover 10, and the anti-electric shock wall cover 13 are made of plastic material.

[0110] Specifically, the outer shell 1, left end cover 10, and anti-electric shock wall cover 13 are made of plastic materials, which are inexpensive and easy to process and mold.

[0111] For example, the plastics used include ABS plastic, PVC plastic or PC plastic.

[0112] Specifically, the outer shell 1, the left end cover 10, and the anti-electric shock wall cover 13 are made by blow molding.

[0113] In other embodiments, the outer casing 1 is shaped as a circle, ellipse, hexagon, or octagon. It is understood that the shape of the outer casing 1 includes, but is not limited to, the types described above.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] Specifically, the stop 14 is connected to the housing 1 by adhesive or fasteners.

[0118] 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.

[0119] In other embodiments, the tank assembly for an electric water heater also includes an inner tank 2 and a bracket 8.

[0120] Combination Figure 12 As shown, the inner liner 2 is disposed 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.

[0121] The bracket 8 includes an inner liner bracket 3 and an outer shell bracket 4. The inner liner bracket 3 is located in the mounting cavity between the inner liner 2 and the outer shell 1. One end of the inner liner bracket 3 is fixed to the outer wall of the inner liner 2 by welding, and the other end of the inner liner bracket 3 abuts against the inner wall of the outer shell 1.

[0122] Combination Figure 6 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.

[0123] The first fastener 5 is configured to connect the inner liner bracket 3 and the outer shell bracket 4 to the outer shell 1.

[0124] Specifically, the first fastener 5 includes a bolt.

[0125] 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.

[0126] Specifically, the outer casing 1 is made of plastic material, which has low thermal conductivity and does not easily transfer heat, thus keeping the heat within the outer casing 1.

[0127] Specifically, the inner tank support 3 separates the inner tank 2 from the outer shell 1, reducing the heat transfer from the inner tank 2 to the outer shell 1; the first fastener 5 connects the inner tank support 3 and the outer shell support 4 to the outer shell 1, realizing the fixed connection of 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 set 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 a good heat insulation effect, the heat insulation pad is eliminated, which helps to reduce production costs and simplify installation.

[0128] In some embodiments of this application, the inner bladder stent 3 is U-shaped or C-shaped, and the structural form of the inner bladder stent 3 includes, but is not limited to, the above types.

[0129] In some 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.

[0130] Specifically, the inner tube support 3 can be obtained by bending sheet metal parts.

[0131] Specifically, the two ear plates 31 are fixed to the inner liner 2 by welding, thereby fixing the inner liner support 3 to 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 surface 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.

[0132] In some embodiments of this application, combined with Figure 7 and Figure 8 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.

[0133] 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.

[0134] Specifically, in combination Figure 9 , Figure 10 and Figure 11 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.

[0135] In some embodiments of this application, the housing support 4 includes a first support portion 41 and a second support portion 42.

[0136] 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.

[0137] 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.

[0138] Specifically, by abutting the first support part 41 against the outer wall of the outer shell 1, the contact area between the first support part 41 and the outer shell 1 is large, which improves the stability of the connection between the outer shell bracket 4 and the outer shell 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 shell 1, so that the hook on the wall can pass through the fixing hole 421 on the second support part 42, thereby realizing the wall-mounted fixing of the electric water heater.

[0139] In some embodiments of this application, the tank assembly for an electric water heater further includes a second fastener 6.

[0140] 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.

[0141] 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.

[0142] In some embodiments of this application, the housing support 4 further includes a third support portion 43 and / or a fourth support portion 44.

[0143] 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.

[0144] 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.

[0145] Specifically, the first support part 41, the second support part 42, the third support part 43 and the fourth support part 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 outer shell bracket 4.

[0146] 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.

[0147] In some embodiments of this application, combined with Figure 12 As shown, the tank assembly for an electric water heater also includes a support pad 7.

[0148] 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.

[0149] Specifically, by setting a support pad 7 on the outer casing 1, the support pad 7 is located below the outer casing bracket 4. 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 falling 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.
