In an embodiment, as shown in fig. 1, the minimum thickness direction of the charging module 130 is in the same direction as the second direction B-B, that is, the minimum thickness direction of the charging module 130 is located in the vertical direction, in order to ensure the use safety of the electric water heater 100, the charging module 130 is disposed close to the top plate 113 and is located at the top end of the battery module 120, so that the accommodating area 150 formed by surrounding the battery module 120, the charging module 130 and the housing 110 is located at the bottom of the charging module 130, that is, the heating module 140 is located at the bottom of the battery module 120, and if the heating module 140 has a water leakage problem, water will not flow to the charging module 130, thereby avoiding potential safety hazards. Specifically, the heating module 140 is disposed near the bottom plate 114, so that the heating module 140 is far away from the charging module 130, and the influence on the charging module 130 caused by water leakage is avoided. By reasonably arranging the position structures of the charging module 130, the heating module 140 and the battery module 120, the volume of the electric water heater 100 can be reduced to the greatest extent, and the overall safety of the electric water heater 100 can be ensured.

In yet another embodiment, the minimum thickness direction of the charging module 130 is the same as the third direction C-C, which is perpendicular to the first direction A-A and the second direction B-B, which is also the horizontal direction since the first direction A-A is generally in the horizontal direction and the second direction B-B is generally in the vertical direction. The charging module 130 is located at the side end of the battery module 120, i.e., at the left and right sides of the battery module 120.

In one embodiment, the charger 131 and the charger control circuit 132 may be arranged side by side to form a block-shaped charging module 130 and be co-located at the side end of the battery module 120. In still another embodiment, if the thickness of the charger 131 and the charger control circuit 132 along the second direction B-B is greater than the thickness of the battery module 120 along the second direction B-B, the charger 131 and the charger control circuit 132 may also be arranged at intervals along the third direction C-C, and the charger 131 and the charger control circuit 132 are respectively located at two side ends of the battery module 120, that is, the charger 131 and the charger control circuit 132 are respectively located at the left and right sides of the battery module 120, and the charger 131 and the charger control circuit 132 are electrically connected through a safety cable. The specific structural arrangement details of the charging module 130, the battery module 120 and the heating module 140 can be adjusted according to practical situations, so as to minimize the volume of the electric water heater 100 and ensure the safety of the whole electric water heater 100.
In order to realize control between the modules of the electric water heater 100, as shown in fig. 1, the electric water heater 100 further includes a control module 190, and the control module 190 is used for collecting relevant parameters and realizing operation control between the modules of the electric water heater 100. The control module 190 is disposed in the accommodating area 150, and a water and electricity isolating plate 160 is disposed between the control module 190 and the heating module 140. The control module 190 and the heating module 140 are separated by the water-electricity separation plate 160, and when water leakage occurs in the heating module 140, the water-electricity separation plate 160 blocks water from flowing to the control module 190, so that the control module 190 is prevented from being damaged by the water leakage.
Preferably, as shown in fig. 1, when the minimum thickness direction of the charging module 130 is the same as the second direction B-B and the heating module 140 is disposed near the bottom plate 114, the control module 190 is located at one side of the heating module 140 in the horizontal direction, or the control module 190 is located at the top of the heating module 140, so as to further avoid the water leakage of the heating module 140 from affecting the operation of the control module 190. When the minimum thickness direction of the charging module 130 is the same as the third direction C-C, the control module 190 is located in the horizontal direction of the heating module 140, i.e. on one side of the third direction C-C, or the control module 190 is located at the top of the heating module 140, so as to further avoid the water leakage of the heating module 140 from affecting the operation of the control module 190.
As shown in fig. 2, the electric water heater 100 further includes a display control panel 1111, the display control panel 1111 is located on the panel 111, and the display control panel 1111 can interact with a user. The display control panel 1111 obtains the operation command of the user and transmits the operation command to the control module 190 to realize the control between the modules of the electric water heater 100. The display control panel 1111 may also display the operation of the electric water heater 100, for example, the display control panel 1111 may display the remaining power of the battery module 120, whether the charging module 130 is charging the battery module 120, the set heating temperature of the heating module 140, the operation temperature of the charging module 130, and the like, which are not listed here.
In order to avoid the influence on other modules when an abnormality occurs in a certain module in the electric water heater 100, as shown in fig. 3, the charging module 130 is wrapped by the first metal shell 171, the first metal shell 171 has explosion-proof and flame-retardant capabilities, and when the charging module 130 is abnormal, the first metal shell 171 plays a role in protection and isolation, so that the other modules are prevented from being influenced, the whole electric water heater 100 is safer, and the maintenance of the electric water heater 100 is facilitated; of course, the first metal case 171 may also protect the internal charging module 130 when an abnormality occurs in other modules. Wherein, the charger 131 and the charger control circuit 132 in the charging module 130 may be integrally wrapped by the first metal case 171. Or the charger 131 and the charger control circuit 132 may be individually wrapped by the first metal case 171 to individually protect the charger 131 and the charger control circuit 132 from being affected by each other when abnormality occurs.
Further, as shown in fig. 3, the battery module 120 is wrapped by the second metal casing 172, the second metal casing 172 has explosion-proof and flame-retardant capabilities, and when the battery module 120 is abnormal, the second metal casing 172 plays a role in protection and isolation, so that other modules are prevented from being affected, the whole electric water heater 100 is safer, and the maintenance of the electric water heater 100 is facilitated; of course, the second metal case 172 may also protect the internal battery module 120 when an abnormality occurs in other modules.
Specifically, as shown in fig. 3, the first metal case 171 and the second metal case 172 may be integrally provided, but of course, the first metal case 171 and the second metal case 172 may also be separately provided independently, without limitation.
In one embodiment, as shown in fig. 1, the heating module 140 includes a water inlet pipe 141, a heating cup 142 and a water outlet pipe 143 connected in sequence, and the water inlet pipe 141 and the water outlet pipe 143 penetrate the housing 110. The water inlet flow enters the heating water cup 142 through the water inlet pipe 141, is heated by the heating water cup 142, and flows out through the water outlet pipe 143.
In an embodiment, as shown in fig. 1, the electric water heater 100 is an instant electric water heater 100, the electric power supply end mainly supplies power to the heating module 140, and when the output power of the electric power supply end does not meet the use requirement, the battery module 120 simultaneously supplies power to the heating module 140, so as to meet the use requirement of the heating module 140.
In the prior art, if a special line is not drawn in a place where the electric power is already in place, the electric power cannot meet the electric power requirement of the instant electric water heater 100, the installation space is limited, and the water storage type electric water heater 100 with larger volume cannot be installed. The electric water heater 100 in the embodiment is powered by the battery module 120 and the mains supply end together, no special line is required to be drawn, only the conventional power supply requirement is required, the installation can be realized in the place where the electric water heater is already in place, the electric water heater 100 adopting the battery module 120 is miniaturized, and the installation space is not limited. In addition, compared with the water storage type electric water heater 100, the instant electric water heater 100 is not easy to generate scale and bacteria.
Of course, in other embodiments, the electric water heater 100 may be a water storage type electric water heater 100, and when the utility power supply end supplies power to the heating module 140, the battery module 120 may supply power to the heating module 140 at the same time, so as to improve the heating efficiency of the heating module 140, shorten the heating time of the heating module 140, reduce the waiting time for user use, and improve the user experience.
In an embodiment, the charging module 130 is a fast charging module 130, and the capacity of the battery module 120 can be reduced by adopting the fast charging module 130, and only a small number of users, for example, 1-2 users, are required to be ensured, so that the volume, weight and cost of the battery module 120 can be reduced, and further the miniaturization of the electric water heater 100 product can be realized. And because the quick charge module 130 charges efficiently, the heat that produces is more, and the heat dissipation of charge module 130 is difficult, and this embodiment absorbs the heat of charge module 130 through the heat accumulation module, can effectively accelerate the heat dissipation of charge module 130, avoids the adverse effect that charge module 130 work produced to the heat that charge module 130 produced to avoid the inside temperature of water heater to rise and influence other module's normal work.
Further, the energy of the battery module 120 is 3kw·h or less, for example, 3kw·h, 2kw·h, or the like, and the output power of the battery module 120 is 6kW or less, for example, 6kW, 5kW, 3kW, or the like. When the energy of the battery module 120 is 3kw·h, the battery module 120 can continuously operate for 30 minutes while the battery module 120 maintains the highest output power of 6kW, and thus the use requirements of a small number of users, for example, 1 to 2 users, are satisfied. The volume of the battery module 120 with the energy of less than 3 kW.h is small, so that the volume, weight and cost of the battery module 120 can be reduced, and further the miniaturization of the electric water heater 100 product is realized. Specifically, the capacity of battery module 120 is 30AH or less, for example, 30AH, 25AH, 20AH, or the like. In one embodiment, when the capacity of the battery module 120 is 25AH, the volume of the electric water heater 100 using 25AH can be less than 45L, and the volume of the conventional water storage type electric water heater 100 needs at least 80L. Specifically, the output voltage of the battery module 120 is 126V or less, for example, 126V, 100V, 90V, 80V, etc., to meet the use requirements.
It should be noted that, the battery module 120 is a ternary lithium battery, and the ternary lithium battery has the characteristics of high multiplying power and high energy density, and has a small volume, so that the volume, weight and cost of the battery module 120 can be reduced, and further, the miniaturization of the electric water heater 100 can be realized. In other embodiments, the battery module 120 may be a solid-state battery, an air battery, or a lithium iron phosphate battery, which also has the effect of reducing the volume, weight, and cost of the battery module 120.
By reducing the volume of the battery module 120 and arranging the battery module 120, the charging module 130, and the heating module 140 reasonably, the volume of the electric water heater 100 can be reduced to the maximum.
Since the charging module 130 generates heat when charging the battery module 120, and when the charging module 130 is a fast charging module 130, the charging process generates a large amount of heat. The electric water heater 100 further includes a heat dissipation component, which is disposed corresponding to the charging module 130. In one embodiment, as shown in fig. 1 and 3, the heat dissipation member includes a first heat dissipation hole 1711 and a second heat dissipation hole 116. The first metal case 171 is provided with a first heat dissipation hole 1711, and the case 110 is provided with a second heat dissipation hole 116, and the first heat dissipation hole 1711 and the second heat dissipation hole 116 are disposed opposite to each other. Because the first metal casing 171 wraps the exterior of the charging module 130, the heat generated by the charging module 130 can radiate from the first radiating hole 1711 and the second radiating hole 116, so as to reduce the temperature of the charging module 130 and avoid the influence of the excessive temperature on the normal operation of the charging module. It should be noted that, the first heat dissipation hole 1711 and the second heat dissipation hole 116 are correspondingly disposed, and the first heat dissipation hole 1711 is disposed on a side of the first metal casing 171 close to the casing 110, that is, the first heat dissipation hole 1711 and the second heat dissipation hole 116 are disposed at positions far away from other modules, for example, in fig. 3, the first heat dissipation hole 1711 is located at the top of the charging module 130, and of course, the first heat dissipation hole 1711 may also be located at the left side of the charging module 130 in fig. 3, so that heat cannot be transferred to other modules of the electric water heater 100, and normal operation of other modules is not affected.
As shown in fig. 1 and 3, the charging module 130 includes a charger 131 and a charger control circuit 132, and the first heat dissipation hole 1711 may be opened only corresponding to the charger 131, and the heat of the charging module 130 is mainly generated by the operation of the charger 131. Of course, the first heat dissipation hole 1711 may also be opened corresponding to the charger 131 and the charger control circuit 132, which is not limited herein.
In other embodiments, the heat dissipation component may also be a heat absorbing member, and the heat absorbing member is disposed corresponding to the charging module 130. The heat absorbing member includes a housing and a phase change material filled in the housing, and the phase change material can absorb heat of the charging module 130, but does not raise excessive temperature, and does not easily transfer heat to other modules. The heat absorbing member is disposed near the charging module 130, and may be located inside or outside the first metal case 171, and preferably, the heat absorbing member is located at a side of the charging module 130 near the case 110, i.e., at a position away from other modules. Specifically, the heat absorbing member may have a rectangular parallelepiped shape.
Of course, in other embodiments, the heat dissipation component may include the first heat dissipation hole 1711, the second heat dissipation hole 116, and the heat absorbing member described above. Preferably, the first heat dissipation hole 1711 and the heat absorbing member are disposed on a side of the charging module 130 near the housing 110, and the first heat dissipation hole 1711, the second heat dissipation hole 116 and the heat absorbing member are disposed correspondingly. The heat absorbing member is attached to the side wall of the charging module, and the heat absorbing member can radiate heat through the first radiating hole 1711 and the second radiating hole 116, so that the temperature of the charging module 130 is effectively reduced.
Since the charging module 130 is a fast charging module 130, when the charging module 130 charges the battery module 120, a large amount of heat is generated, and the battery module 120 is heated to have a great effect on the performance and the use of the battery module, as shown in fig. 1, in order to avoid the charging module 130 from affecting the operation of the battery module 120, a heat insulation member 180 is disposed between the charging module 130 and the battery module 120. The heat insulating member 180 may be a heat insulating material such as de nailong, and blocks the heat of the charging module 130 from being transferred to the battery module 120, so as to ensure that the heat generated by the operation of the charging module 130 is not conducted to the battery module 120, and the overall design of the electric water heater 100 is safer. Specifically, the heat insulating member 180 is positioned between the charging module 130 and the battery module 120, the heat insulating member 180 completely covers one side of the charging module 130 adjacent to the battery module 120, and the heat insulating member 180 has a layered or plate-shaped structure having a certain thickness in order to reduce the volume. The thickness of the heat insulating member 180 from the charging module 130 to the battery module 120 can be adjusted according to practical situations, so as to avoid the heat of the charging module 130 from affecting the battery module 120, and simultaneously reduce the volume of the electric water heater 100 as much as possible.
In other embodiments, the thermal insulation member 180 may also be a phase change material that can absorb heat, and the thermal insulation member 180 includes a housing and a phase change material filled in the housing, where the phase change material can absorb heat of the charging module 130, but does not raise excessive temperature and is not easy to transfer heat to the battery module 120. Therefore, the heat insulator 180 is not only beneficial to heat dissipation of the charging module 130, but also prevents heat from being transferred to the battery module 120, so that the overall design of the electric water heater 100 is safer.
By arranging the heat insulator 180 on one side of the charging module 130 close to the battery module 120 and arranging the heat radiating component on one side close to the shell 110, on one hand, heat transfer of the charging module 130 to the battery module 120 is blocked, and on the other hand, heat radiation of the charging module 130 is quickened, so that the temperature of the charging module 130 is effectively reduced, and the whole design of the electric water heater 100 is safer; further, due to the combined heat insulation and heat dissipation effects of the heat insulator 180 and the heat dissipation member, the internal structure of the electric water heater 100 can be designed more compactly, thereby achieving miniaturization of the electric water heater 100.
The foregoing description is only illustrative of the present application and is not intended to limit the scope of the application, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present application.
