As shown in fig. 1 to 5, the housing 1 of the electric water heater of the present embodiment is generally mounted on a wall through a wall hanger 14, wherein the wall hanger 14 includes a first connecting frame 141 and a second connecting frame 142, the first connecting frame 141 is fixed on the housing 1, and the second connecting frame 142 is mounted on the wall. In order to meet the demand for a slim and light installation to save an installation space, the back of the case 1 is provided with an installation space (not labeled) extending toward the inside of the case 1; wherein the first connection frame 141 is fixed in the installation space, and the second connection frame 142 is used for being fixed on a wall to hang the first connection frame 141; in actual use, the second connecting frame 142 is fixedly mounted on the wall by means of bolts or the like, and the housing 1 is hung on the second connecting frame 142 by the first connecting frame 141, and at this time, part or all of the second connecting frame 142 is located in the mounting space. Specifically, since the installation space extending toward the inner recess of the housing 1 is formed, the first connection frame 141 is installed and fixed in the installation space, so that the first connection frame 141 can be hidden in the housing 1, thereby preventing the first connection frame 141 from being externally arranged outside the housing 1 and increasing the thickness. When the shell 1 is required to be hung, the first connecting frame 141 is hung on the second connecting frame 142, and at this time, a part or all of the second connecting frame 142 extends into the installation space, so that the thickness space of the shell 1 can be used to accommodate the second connecting frame 142. In the actual use process, under the condition that the first connecting frame 141 and the second connecting frame 142 are well connected, the second connecting frame 142 can be completely located in the installation space, and the part of the second connecting frame 142 attached to the wall is exposed outside the installation space under the influence of the installation level of the operator, the wall installation environment of the user at home and other factors, but in the whole, after the shell 1 is hung on the wall through the wall hanging frame 14, the space occupied by the shell 1 is basically the same as the thickness of the shell, so that the extra occupied space of the wall hanging frame 14 can be effectively reduced.

The first connecting frame 141 is provided with a first hanging portion, the second connecting frame 142 is provided with a second hanging portion matched with the first hanging portion, and the first hanging portion is hung on the second hanging portion. Specifically, the first hanging part and the second hanging part have various structural forms. For example, the first hanging portion is a hook provided on the first link 141, and the second hanging portion is a hanging hole provided on the second link 142, in which the hook is hung. Also, in order to improve connection reliability and installation convenience, the first hanging portion is a hanging plate 1411 provided on the first connecting frame 141 to extend downward, and the second hanging portion is a supporting plate 1421 provided on the second connecting frame 142 to extend upward, and the hanging plate 1411 is inserted in an area formed between the supporting plate 1421 and the second connecting frame 142 when the suspension housing 1 is installed. As for the hanging plate 1411 and the supporting plate 1421, the hanging plate 1411 may be integrally formed on the first connecting frame 141, and similarly, the supporting plate 1421 may be integrally formed on the second connecting frame 142, specifically, the first connecting frame 141 and the second connecting frame 142 are respectively in a strip shape, and taking the first connecting frame 141 as an example, the hanging plate 1411 may be directly formed on the first connecting frame 141 by bending and stamping a plate material, so that after the first connecting frame 141 is installed in the installation space, the first connecting frame 141 is integrally formed into an inverted U-shaped structure or an inverted J-shaped structure in longitudinal section. Correspondingly, the first connecting frame 141 is integrally formed to have a U-shaped or J-shaped longitudinal section.

Preferably, in order to facilitate the installation of the housing 1 by an operator and enable the housing 1 to be maximally attached to a wall to reduce the exposed amount of the second connecting frame 142, the supporting plate 1421 is bent upward from the lower portion of the second connecting frame 142, and the supporting plate 1421 extends upward obliquely away from the side of the main body of the second connecting frame 142. Thus, during actual installation, the housing 1 is lifted to make the hanging plate 1411 higher than the upper edge of the supporting plate 1421, the hanging plate 1411 is inserted between the supporting plate 1421 and the second connecting frame 142 and slides downwards along the supporting plate 1421, and by using the inclined guiding of the supporting plate 1421, in the descending process of the housing 1, the hanging plate 1411 drives the housing 1 to gradually move close to the second connecting frame 142, and finally, the housing 1 can cling to the wall and make the second connecting frame 142 enter the installation space. In addition, the installation space of the housing 1 may be disposed at the top region of the housing 1, that is, the installation space is formed at the connection portion of the backboard 12 and the top of the frame 13, and correspondingly, the first connection frame 141 is located at the top of the housing 1. And the periphery on the front panel 11 can be provided with flange structure in order to wrap around the frame 12, for example: the upper edge of the front panel 11 forms a first flange structure 111, the first flange structure 111 can extend to the back of the housing 1 and be flush with the rear panel 12, and the first flange structure 111 is used to cover the first connecting frame 141 in the installation space to optimize the appearance effect. Meanwhile, two side edges on the front panel 11 respectively form second flanging structures 112, and the second flanging structures 112 can extend to the back of the housing 1 and are flush with the rear back panel 12; the lower limb of front panel 11 forms third turn-ups structure 113, and third turn-ups structure 113 pastes and leans on in the bottom of frame 13, like this for front panel 11 wholly is housing formula structure, and front panel 11 wraps up around frame 13 through turn-ups structure, makes the whole outward appearance of shell 1 more pleasing to the eye.

Further, a positioning insertion plate 1412 extending downwards is arranged on the hanging plate 1411, a positioning hole 1422 is arranged on the second connecting frame 142, and the positioning insertion plate 1412 is inserted into the positioning hole 1422. Specifically, after the first connecting frame 141 is hung on the second connecting frame 142, the positioning insertion plate 1412 is inserted into the corresponding positioning hole 1422 to limit the lateral movement of the first connecting frame 141 on the second connecting frame 142, so as to improve the mounting reliability. In addition, since the second connecting frame 142 is usually installed on the wall by using a bolt fixing method, the back of the second connecting frame 142 is provided with a plurality of installation holes 1423 for installing wall hanging bolts, the supporting plate 1421 is provided with first notches 1424 matched with the installation holes, and the first notches 1424 are arranged opposite to the corresponding installation holes 1423; thus, when the second connecting frame 142 is installed, the bolt can pass through the first notch 1424 and the installation hole 1423 to be connected to the wall, and the bolt avoids the supporting plate 1421 through the first notch 1424, so as to avoid the interference influence of the supporting plate 1421 on the installation of the bolt. Meanwhile, the first connecting frame 141 is provided with a second notch 1413 matched with the first notch 1424, since the end of the bolt is exposed outside the second connecting frame 142 after the bolt is fixedly installed on the wall, after the first connecting frame 141 is installed on the second connecting frame 142, the exposed end of the bolt is located in the second notch 1413, and the hanging plate 1411 can avoid the end of the bolt through the second notch 1413, so that the installation convenience is improved.

Based on the above technical solution, optionally, for meeting the water supply requirement of the instant heating type large water volume of the user, as shown in fig. 1-2 and 6-7, the housing 1 of the electric water heater in this embodiment is further provided with an electric heating module 2, an electric storage module 3, a charging and discharging module 4 and a controller 5, wherein the electric heating module 2, the electric storage module 3, the charging and discharging module 4 and the controller 5 are installed in the housing 1, the housing 1 is provided with a water inlet pipe 101 and a water outlet pipe 102, the water inlet pipe 101 is connected with an external water supply source (for example, a tap water pipe) for introducing cold water, and the water outlet pipe 102 is used for outputting hot water. In the actual use process, the charge and discharge module 4 can charge and discharge the power storage module 3, and supply the electric energy released by the power storage module 3 to the electric heating module 2 for heating, the water delivered by the external water supply source to the electric heating module 2 is rapidly heated by the electric heating module 2 to achieve the purpose of instant heating type water supply, and in a normal case, a temperature sensor for detecting temperature and a flow sensor for detecting water flow are configured on the water heater, and the controller 5 controls the operation of the charge and discharge module 4 according to the user set parameters and signals detected by the relevant sensors.

The basic functions of the above modules are explained: the electric heating module 2 generally comprises a heating container and an electric heating part, the heating container is provided with a water inlet and a water outlet, water conveyed by a water supply source enters the heating container from the water inlet through a water inlet pipe 101, the electric heating part obtains electric energy to heat water flowing in the heating container, heated hot water is output from the water outlet of the heating container and conveyed to the outside through a water outlet pipe 102, and the electric heating part can adopt electric heating pipes, electric heating films and other electric heating devices; the electric storage module 3 stores electric energy by using a plurality of storage batteries, and the storage batteries can be of the existing common battery types, such as lithium batteries or nickel-cadmium batteries, and the embodiment does not limit the specific form of the storage batteries; the charging and discharging module 4 generally has a battery charging unit and a battery discharging unit, the battery charging unit is connected to the commercial power to charge the storage battery according to the requirement, the battery discharging unit is connected to the electric heating component, the electric energy released by the storage battery is applied to the electric heating component through the battery discharging unit to supply power to the electric heating component, the battery charging unit and the battery discharging unit can adopt the conventional battery charging circuit and battery discharging circuit form, and the limitation is not made herein; the controller 5 is used as a main control component and can control the operation of the electric water heater according to a command mode set by a user, the controller 5 generally comprises a circuit board and a control chip arranged on the circuit board, since the Battery is used to supply power, the controller 5 may be further configured with a Battery Management System (BMS), which is used to monitor the Battery, for example, accurately estimate the State of Charge (SOC) of the power Battery, namely the residual electric quantity of the battery, collects the parameters of voltage, temperature, current and the like of each storage battery in real time in the charging and discharging process, prevents the overcharge or overdischarge phenomenon, and the single storage battery is charged in a balanced manner so as to ensure that each storage battery in the storage module achieves a balanced and consistent state, in addition, the controller 5 may also be configured with a display screen or a display touch screen for a user to check the operation state of the electric water heater.

Because the charge-discharge module 4 is arranged inside the housing 1, the charge-discharge module 4 generates heat when controlling the charge or discharge of the power storage module 3, and if the heat is accumulated inside the housing 1 and cannot be released quickly, the operation reliability of the charge-discharge module 4 is affected due to the overhigh temperature inside the housing 1, and therefore, the housing 1 is provided with the heat dissipation opening 10; meanwhile, the charge and discharge module 4 is provided with a heat sink 41, the heat sink 41 is used for mounting the charge and discharge module 4 and for dissipating heat released by the charge and discharge module 4, and the heat sink 41 is disposed in the heat dissipation opening 10. Specifically, in the charging and discharging process of the charging and discharging module 4, the heat generated by the charging and discharging module 4 is absorbed by the heat sink 41, and the heat sink 41 is located in the heat dissipation opening 10, so that the cold air outside the housing 1 can exchange heat with the heat sink 41 located in the heat dissipation opening 10, so as to dissipate the heat generated by the charging and discharging module 4 by using the heat sink 41. In actual use, since the heat generated by the charge and discharge module 4 can be rapidly dissipated to the outside of the case 1 through the heat sink 41, the charge and discharge module 4 can be reliably operated.

In addition, the heat sink 41 may be made of a material with good thermal conductivity, such as: copper and aluminum, and the like. In order to improve the heat dissipation efficiency, the heat sink 41 includes: a heat dissipation substrate 411 and a plurality of heat dissipation fins 412, wherein the heat dissipation substrate 411 is disposed on the charge and discharge module 4 and is used for absorbing heat released by the charge and discharge module 4; the heat dissipation fins 412 are disposed on the heat dissipation substrate 411, and the heat dissipation fins 412 are inserted into the heat dissipation openings 10. Specifically, the heat dissipation substrate 411 may be connected to the charge/discharge module 4 by means of screw fixation or snap connection, and in order to improve the heat transfer efficiency, a heat conductive adhesive is further disposed between the charge/discharge module 4 and the heat dissipation substrate 411. In this way, the charge/discharge module 4 can rapidly transfer heat to the heat dissipation substrate 411, and the heat dissipation substrate 411 transfers heat to the heat dissipation fins 412. The heat dissipating fins 412 located in the heat dissipating opening 10 can be in sufficient contact with the outside air to perform heat exchange, thereby achieving rapid heat dissipation. By using the principle of hot air rising, the heat dissipating fins 412 are vertically arranged in the heat dissipating opening 10, that is, a plurality of heat dissipating fins 412 are longitudinally arranged in the heat dissipating opening 10, and a heat dissipating air duct is formed between two adjacent heat dissipating fins 412. The heat generated by the charge and discharge module 4 is finally transferred to the heat dissipation fins 412, the heat dissipation fins 412 heat the air around the heat dissipation fins to form hot air, and the heated air around the heat dissipation fins 412 rises by utilizing the principle of hot air rising, so that the cold air below the heat dissipation fins 412 is sucked into the heat dissipation air duct, and thus, the heat dissipation efficiency can be improved more quickly and efficiently.

The position of the heat dissipation opening 10 on the housing 1 is set according to the installation position of the heat sink 41, for example: the heat dissipation opening 10 may be provided at the back or the side of the case 1. Whereas the housing 1 generally comprises a front panel 11, a bezel 13 and a back panel 12, the bezel 13 being located between the front panel 11 and the back panel 12, the front panel 11 and the back panel 12 being mounted to the bezel 13 to form the housing 1, respectively; the back plate 12 is provided with a groove structure 121 which is concave towards the inside of the shell 1, and the heat dissipation opening 10 is positioned in the groove structure 121; the heat sink 41 extends from the inside of the housing 1 through the heat dissipation opening 10 and into the groove structure 121. Specifically, the back plate 12 may be formed with the groove structure 121 by stamping, and the heat dissipation opening 10 is formed in the groove structure 121, so that the heat dissipation opening 10 with a large area can be formed on the back plate 12 to mount the large-sized heat sink 41, thereby improving the heat dissipation efficiency. After the housing 1 is mounted on the wall, a structure similar to an air duct is formed between the groove structure 121 formed on the back plate 12 and the wall, on one hand, the requirement that the heat dissipation fins 412 with a larger area extend out of the heat dissipation opening 10 to enable the heat dissipation fins 412 with the larger area to be in contact with outside cold air for heat dissipation can be met, on the other hand, the heat dissipation fins 412 extending out of the heat dissipation opening 10 are still located in the groove structure 121, the wall-mounted mounting of the housing 1 cannot be influenced, and the situation that the heat dissipation fins 412 extending out of the heat dissipation opening 10 extend out of the back plate 12 to influence the mounting is avoided.

Preferably, in order to enable the cold air at the bottom of the housing 1 to smoothly enter the groove structures 121 to exchange heat with the heat dissipation fins 412, the bottom of the frame 13 is provided with notch structures 131 connected with the groove structures 131; the hot air heated by the heat sink 41 flows upward in the groove structure 121, and the external cold air is sucked into the groove structure 121 through the notch structure 131. Specifically, the notch structure 131 formed at the bottom of the frame 13 serves as a cold air inlet, the heat dissipation fins 412 in the groove structure 121 heat the air and the air rises through the gap between the housing 1 and the wall and flows out of the groove structure 121, and the cold air at the bottom of the housing 1 can rapidly enter the groove structure 121 through the notch structure 131 to cool the heat dissipation fins 412. The air duct-like structure formed between the groove structure 121 and the wall can form a certain negative pressure at the notch structure 131 to suck the cold air at the bottom of the housing 1 under the action of the rising hot air, so as to accelerate the air flowing speed on the surface of the heat dissipation fin 412.

The heat dissipation opening is formed in the shell, the radiator is additionally arranged on the charge-discharge module and is arranged in the heat dissipation opening, and in the charge-discharge process, heat generated by the charge-discharge module is absorbed by the radiator and is released to the outside of the shell through the heat dissipation opening, so that the heat dissipation efficiency is improved by quickly dissipating the heat, the situation that the charge-discharge module breaks down due to high temperature in the sealed shell is avoided, and the use reliability is improved.
