[0033] An electric water heater uses electricity as its main energy source. The high-temperature heat generated after power is turned on directly heats the water stored in the electric water heater to prepare hot water.
[0034] An electric water heater usually includes a water tank, an electric heating component, an electric control board and other components. A water storage cavity is formed in the water tank to store the water to be heated. The electric heating component is inserted into the water storage cavity formed by the water tank. The electric control board is used to control the on and off operation of the electric heating component so that the water in the water tank is heated to a set temperature.
[0035] For the water tank of an electric water heater, the water tank generally includes an outer shell and an inner tank, and an insulation layer is formed between the outer shell and the inner tank. Among them, the outer shell is generally made of plastic material to meet the design requirements of beautiful and diverse shapes; the inner tank can be made of metal or plastic according to needs.
[0036] In addition, the insulation layer formed between the outer shell and the inner liner, commonly used insulation materials include: asbestos, sponge, foam plastic, polyurethane foam, etc. In conventional technology, in order to obtain a good insulation effect, the insulation layer is usually formed by foaming.
[0037] Among them, for the inner tank using a metal tank body, the interior of the inner tank is prone to corrosion due to the influence of water quality. For this reason, a magnesium rod is also configured on the water tank, and the magnesium rod is inserted into the water storage cavity inside the water tank.
[0038] Since magnesium is the metal with the lowest potential in the electrochemical series and is physiologically non-toxic, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod is directly related to the length of time the inner liner is protected and the size of the protective effect. The larger the magnesium rod, the better the protective effect and the longer the protection time.
[0039] The water tank is also provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is used to transport cold water to the water storage cavity formed in the water tank, while the hot water in the water storage cavity is output from the water outlet pipe.
[0040] For the electric heating component, electric heating methods such as electric heating wire, magnetic energy or silicon tube heating can be used to heat the water stored in the water storage cavity.
[0041] As for the electric control board, it is used to receive the detection signals sent by relevant sensors (such as water temperature sensors, flow sensors), and at the same time, control the power on and off operation of the electric heating components.
[0042] When the electric water heater is working, the electric control board controls the electric heating component to be powered on for heating. When the water temperature in the water tank reaches the set value, the electric control board controls the electric heating component to be powered off.
[0043] In the first aspect, combined Figures 1 to 12 As shown, the present invention provides a tank body assembly for an electric water heater, and the tank body assembly for the electric water heater comprises a shell 1 and a panel assembly 9.

[0046] The housing 1 and the anti-electricity wall cover 13 are an integrated structure.
[0047] Specifically, an opening 12 is provided on the outer shell 1, and an anti-electricity wall cover 13 is provided at the opening 12. The outer shell 1 and the anti-electricity wall cover 13 are an integrated molding structure, and the anti-electricity wall cover 13 does not need to be manufactured separately by mold opening, which is beneficial to reducing production costs; at the same time, the anti-electricity wall cover 13 does not need to be assembled with the outer shell, which simplifies the process, is beneficial to improving production efficiency, and saves manpower; the panel assembly 9 includes a front panel 91 and a control panel 92, the front panel 91 is arranged on the anti-electricity wall cover 13 and faces the user side, and the control panel 92 is arranged on the front panel 91 and extends into the accommodating cavity through the installation opening 1311, which is convenient for assembly and user operation.
[0048] In some embodiments of the present application, Figure 3 , Figure 4 The electric shock protection wall cover 13 shown includes a mounting plate 131 , a back plate 132 and two side plates 133 .
[0049] The mounting plate 131 faces the user side. The mounting plate 131 extends downward from the upper edge of the opening 12 . A mounting opening 1311 is disposed on the mounting plate 131 .

[0053] Specifically, by providing a mounting port 1311 on the mounting plate 131, it is convenient to place the control panel 92 in the accommodating cavity; the mounting plate 131, the back plate 132, and the side plate 133 are connected in pairs and are integrally formed with the outer shell 1, which is convenient for processing and manufacturing, and eliminates the assembly step of the anti-electric wall cover 13 on the outer shell, which is beneficial to reducing costs and improving assembly efficiency.
[0054] In some embodiments of the present application, a plurality of slots 1312 are formed on the mounting plate 131 , a plurality of snap-fitting portions 911 are provided on the front panel 91 , and the front panel 91 is snap-fitted into the slots 1312 via the snap-fitting portions 911 .
[0055] Specifically, the plurality of card slots 1312 correspond to the plurality of card connection parts 911 one by one, and the card connection parts 911 cooperate with the card slots 1312 to enable the front panel 91 and the mounting plate 131 to be assembled together, thereby achieving screw-free installation and improving assembly efficiency.
[0056] In addition, in order to improve the connection stability between the front panel 91 and the mounting plate 131 , a plurality of slots 1312 are arranged on the mounting plate 131 around the mounting opening 1311 .
[0057] The above-mentioned front panel 91 is mainly slidably connected with the card slot 1312 and the mounting plate 131 through the card portion 911. When the front panel 91 is installed in place, in order to prevent the front panel 91 from slipping relative to the mounting plate 131 and affecting the use, an auxiliary card portion 912 is also provided on the front panel 91, and an auxiliary groove 1313 is provided at a position corresponding to the auxiliary card portion 912 on the mounting plate 131. In this way, when the card portion 911 of the front panel 91 is installed in place in the card slot 1312, the corresponding auxiliary card portion 912 is inserted into the auxiliary groove 1313, so that the front panel 91 can be prevented from sliding relative to each other.
[0058] In some embodiments of the present application, the plurality of slots 1312 are all tightened in the same direction, so that the clamping portion 911 and the slots 1312 can be more tightly engaged, thereby preventing the front panel 91 from shaking relative to the mounting plate 131 and improving the stability of the connection between the front panel 91 and the mounting plate 131.
[0059] In another embodiment, the engaging portion 911 is a latch extending toward the left.
[0060] In certain embodiments of the present application, the control panel 92 includes a rear shell plate 921 and a circuit board 922 .
[0061] The rear shell plate 921 is arranged on the front panel 91; specifically, grooves (not marked) are arranged at both ends of the rear shell plate 921, and claws (not marked) are arranged at positions corresponding to the grooves on the front panel 91, and the claws are inserted into the grooves to realize the connection between the rear shell plate 921 and the front panel 91.
[0062] The circuit board 922 is fixed on the rear shell plate 921 by screws.
[0063] Specifically, by providing the rear shell plate 921 , the rear shell plate 921 is connected to the front panel 91 , so that the circuit board 922 can be easily installed.
[0064] Specifically, the circuit board 922 is configured with a display screen and touch buttons as needed.
[0065] Correspondingly, a touch area and a display area are provided on the front panel 91, the touch buttons are arranged at the rear of the touch area, and the display screen is arranged at the rear of the display area.
[0066] In some embodiments of the present application, Figure 2 As shown, the tank body assembly for the electric water heater further includes a left end cover 10 and a right end cover 20 .
[0067] The left end cover 10 and the housing 1 are an integrally formed structure, the right end cover 20 and the housing 1 are detachably connected, and a maintenance cover 201 is provided on the right end cover 20 .
[0068] Specifically, by configuring the left end cover 10 and the outer shell 1 as an integrally formed structure, there is no need to manufacture the left end cover 10 separately, which is beneficial to saving 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.
[0069] The right end cover 20 is provided with an electrical installation slot, and the electrical installation slot and the maintenance cover 201 form an electrical room (not marked), in which an electrical control board (not marked) is arranged. The electrical control board is electrically connected to the control board 92 through a cable.
[0070] Specifically, in order to facilitate the passage of cables, a cable groove is provided on the rear shell plate 921, and a cable hole is also provided on the right end cover 20.
[0071] In some embodiments of the present application, the housing 1, the left end cover 10 and the anti-electrical wall cover 13 are made of plastic material.
[0072] Specifically, the outer shell 1, the left end cover 10 and the anti-electrical wall cover 13 are made of plastic materials, which has low cost and is easy to process and shape.
[0073] Exemplarily, the plastics used include ABS plastics, PVC plastics or PC plastics.
[0074] Specifically, the housing 1, the left end cover 10 and the anti-electrical wall cover 13 are made by blow molding.
[0075] In other embodiments, the shape of the housing 1 is circular, elliptical, hexagonal or octagonal. It is understood that the shape of the housing 1 includes but is not limited to the above types.
[0076] In some embodiments of the present application, in order to form the outer shell 1 and the anti-electrical wall cover 13 as one piece so that the material can flow to fill the entire molding die 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-electrical wall cover 13.
[0077] During the preparation of the electric water heater, in order to improve the thermal insulation effect of the electric water heater, it is necessary to inject foaming material 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 an opening 12 is provided on the outer shell 1, the foaming material will inevitably flow into the anti-electricity wall cover 13 through the opening 12. The circuit board 922 in the anti-electricity wall cover 13 is connected to the electric control board in the electrical room through a cable. When the foaming material enters the anti-electricity wall cover 13, it will affect the later maintenance of the cable.
[0078] Therefore, the tank assembly for the electric water heater also includes a stopper 14, which is arranged at the opening 12 and located on the inner side of the shell 1. The stopper 14 can cover the opening 12 and prevent the foaming material in the shell 1 from entering the accommodating cavity of the anti-electrical wall cover 13.
[0079] Specifically, the stopper 14 is connected to the housing 1 by gluing or fixing with fasteners.
[0080] Specifically, the stopper 14 is in an arc-shaped structure and matches the inner wall surface of the housing. Of course, the shape of the stopper 14 includes but is not limited to the above-mentioned types.
[0081] In other embodiments, the tank body assembly for the electric water heater further includes an inner tank 2 and a hanging rack 8 .
[0082] Combination Fig.12As shown, the inner liner 2 is arranged in the outer shell 1, and the inner liner 2 and the outer shell 1 enclose a mounting cavity, and the inner liner 2 is made of metal material.
[0083] The bracket 8 includes an inner liner bracket 3 and an outer shell bracket 4. The inner liner bracket 3 is located in the installation cavity between the inner liner 2 and the outer shell 1. One end of the inner liner bracket 3 is fixed on the outer wall surface of the inner liner 2 by welding, and the other end of the inner liner bracket 3 is abutted against the inner wall surface of the outer shell 1.
[0084] Combination Figure 6 As shown, the housing bracket 4 is arranged on the outer wall surface of the housing 1, and the housing bracket 4 is configured to fix the electric water heater on the wall.
[0085] The first fastener 5 is configured to connect the liner bracket 3 and the shell bracket 4 to the shell 1 .
[0086] Specifically, the first fastener 5 includes a bolt.
[0087] During installation, a rubber pad is sleeved on the screw rod of the bolt near the bolt head. The rubber pad can increase the contact area and reduce the pressure; it can also reduce the vibration and looseness of the bolt and improve the fixing effect of the bolt; at the same time, the rubber pad plays a filling and sealing role between the bolt and the housing bracket 4.
[0088] Specifically, the housing 1 is made of a plastic material, which has low thermal conductivity and is not easy to transfer heat, so that the heat is kept in the housing 1 .
[0089] Specifically, the inner tank bracket 3 separates the inner tank 2 and the outer shell 1 to reduce the heat transfer from the inner tank 2 to the outer shell 1; the first fastener 5 connects the inner tank bracket 3 and the outer shell bracket 4 to the outer shell 1, thereby realizing the fixed connection between the outer shell bracket 4, the outer shell 1, the inner tank bracket 3 and the inner tank 2; the outer shell bracket 4 is arranged 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 bracket 4. The outer shell 1 is made of plastic material. Since the outer shell 1 made of plastic material itself has a good thermal insulation effect, the thermal insulation pad is omitted, which is beneficial to reduce production costs and simplify installation.
[0090] In some embodiments of the present application, the inner liner support 3 is U-shaped or C-shaped, and the structural form of the inner liner support 3 includes but is not limited to the above-mentioned types.
[0091] In some embodiments of the present application, one end of the inner liner bracket 3 has two ear plate portions 31, and the two ear plate portions 31 are respectively fixedly connected to the inner liner 2. A bending portion 32 protruding outward relative to the inner liner 2 is formed between the two ear plate portions 31 of the inner liner bracket 3, and the bending portion 32 abuts against the inner wall surface of the outer shell 1.
[0092] Specifically, the inner liner bracket 3 can be obtained by bending a sheet metal part.
[0093] Specifically, the two ear plate portions 31 are fixed to the inner liner 2 by welding, respectively, so that the inner liner bracket 3 is fixed to the inner liner 2, and a bending portion 32 protruding outward relative to the inner liner 2 is formed between the two ear plate portions 31. The bending portion 32 is connected to the ear plate portion 31, and the bending portion 32 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, avoiding the inner liner 2 and the outer shell 1 from being close to each other, and improving the thermal insulation effect.
[0094] In some embodiments of the present application, Figure 7 and Figure 8 As shown, the housing bracket 4 is provided with a first mounting hole 411 , the housing 1 is provided with a second mounting hole 11 , the bending portion 32 is provided with 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 .
[0095] 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, which has a simple structure, reliable connection and convenient disassembly and assembly.
[0096] Specific, combined Fig. 9 , Fig.10 and Fig.11 As shown, a protrusion 322 is formed on the surface of the bending portion 32 facing the inner liner 2, and the protrusion 322 corresponds to the position of the threaded hole 321. The protrusion 322 extends the depth of the threaded hole 321, which is beneficial to improving the reliability of the connection between the first fastener 5 and the bending portion 32.
[0097] In some embodiments of the present application, the housing bracket 4 includes a first supporting portion 41 and a second supporting portion 42 .
[0098] The first supporting portion 41 is in contact with the outer wall of the housing 1 , and a first mounting hole 411 is provided on the first supporting portion 41 .
[0099] One end of the second support portion 42 is connected to the first support portion 41 , and the other end is spaced apart from the housing 1 . A fixing hole 421 is provided on the second support portion 42 , and the fixing hole 421 is configured for a hook on the wall to pass through so as to fix the electric water heater on the wall.
[0100] Specifically, by abutting the first support portion 41 against the outer wall surface of the shell 1, the contact area between the first support portion 41 and the shell 1 is larger, thereby improving the stability of the connection between the shell bracket 4 and the shell 1; the second support portion 42 is connected to the first support portion 41, and there is a gap between the other end of the second support portion 42 and the shell 1, which facilitates the hook on the wall to pass through the fixing hole 421 on the second support portion 42, thereby realizing the wall fixing of the electric water heater.
[0101] In some embodiments of the present application, the tank assembly for the electric water heater further includes a second fastener 6 .
[0102] The first support portion 41 further defines a limiting hole 412 , which is configured to allow the second fastener 6 to pass through so as to fix the housing bracket 4 to the housing 1 .
[0103] Specifically, when the outer shell bracket 4, the outer shell 1 and the inner shell bracket 3 are fixedly connected only by the first fastener 5, when the outer shell bracket 4 is subjected to external force, the outer shell bracket 4 is easy to rotate. By opening a limiting hole 412 on the first support portion 41, the second fastener 6 passes through the limiting hole 412 to fix the outer shell bracket 4 with 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.
[0104] In some embodiments of the present application, the housing bracket 4 further includes a third supporting portion 43 and / or a fourth supporting portion 44 .
[0105] The third support portion 43 is connected between the first support portion 41 and the second support portion 42 . The fourth support portion 44 is connected between the first support portion 41 and the second support portion 42 and is arranged opposite to the third support portion 43 .
[0106] Specifically, by providing the third support portion 43 and / or the fourth support portion 44 , it is helpful to strengthen the connection strength between the first support portion 41 and the second support portion 42 .
[0107] Specifically, the first support portion 41 , the second support portion 42 , the third support portion 43 and the fourth support portion 44 enclose a receiving groove 45 , and the head of the first fastener 5 is located in the receiving groove 45 , so as to prevent the first fastener 5 from interfering with the installation of the housing bracket 4 .
[0108] Specifically, the edges of the first support portion 41 , the second support portion 42 , the third support portion 43 and the fourth support portion 44 are all on the outer end surface of the outer shell bracket 4 . During installation, the outer end surface of the outer shell bracket 4 abuts against the wall.
[0109] In some embodiments of the present application, Fig.12 As shown, the tank body assembly for the electric water heater also includes a supporting pad 7.
[0110] The support pad 7 is disposed on the housing 1 and is 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 on the wall.
[0111] Specifically, by arranging a support pad 7 on the outer shell 1, the support pad 7 is located below the outer shell bracket 4. When the electric water heater is hung on the wall, the support pad 7 can support the outer shell 1 to prevent the outer shell 1 from retreating. In this way, the support pad 7 cooperates with the outer shell bracket 4 to provide support for the installation of the electric water heater on the wall.
[0112] In some embodiments of the present application, the outer end surface of the support pad 7 and the outer end surface of the housing bracket 4 are in the same plane.
[0113] Specifically, by arranging the outer end surface of the support pad 7 and the outer end of the outer shell bracket 4 in the same plane, the stability of the installation of the electric water heater can be improved, and the outer shell bracket 4 can be prevented from being deformed.
[0114] In some embodiments of the present application, the housing 1, the left end cover 10, the anti-electrical wall cover 13 and the supporting pad 7 are integrally formed by a blow molding process.
[0115] Exemplarily, the material used for the housing 1, the left end cover 10, the anti-electrical wall cover 13 and the supporting pad 7 is plastic, and the type of plastic used includes one or more combinations of ABS plastic, PVC plastic or PC plastic.
[0116] Specifically, the present application has a simple structure and does not require additional molds to manufacture the left end cover 10, the anti-electricity wall cover 13 and the supporting pad 7 separately. The steps of assembling the left end cover 10, the anti-electricity wall cover 13 and the supporting pad 7 with the outer shell 1 are eliminated, which can improve production efficiency and reduce costs. The integrated structure enhances the stability and reliability of the installation of the electric water heater.
