In an embodiment, as shown in fig. 1, the minimum thickness direction of the charging module 130 is the same as the second direction B-B, that is, the minimum thickness direction of the charging module 130 is located in a vertical direction, in order to ensure the safe use of the electric water heater 100, the charging module 130 is disposed near the top plate 113 and located at the top end portion of the battery module 120, so that the accommodating area 150 formed by the enclosure of 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 does not flow to the charging module 130, thereby avoiding a potential safety hazard. Specifically, the heating module 140 is disposed close to the bottom plate 114, so that the heating module 140 is far away from the charging module 130, thereby avoiding the influence on the charging module 130 when water leakage occurs. Through the reasonable arrangement of 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 safety of the whole electric water heater 100 can be ensured.

The charger 131 and the charger control circuit 132 may be arranged side by side to form a charging module 130 in a block shape and be located at the top end portion of the battery module 120.
In yet another embodiment, the minimum thickness direction of the charging module 130 is the same direction as the third direction C-C, which is perpendicular to the first direction a-a and the second direction B-B, and since the first direction a-a is generally in a horizontal direction and the second direction B-B is generally in a vertical direction, the third direction C-C is also in a horizontal 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. The accommodating area 150 defined by the battery module 120, the charging module 130 and the housing 110 is located at a side portion of the charging module 130, and the charging module 130 and the heating module 140 are arranged at intervals along the third direction C-C, i.e., the charging module 130 and the heating module 140 are arranged at intervals along the horizontal direction. Therefore, if the heating module 140 has a water leakage problem, water cannot flow to the charging module 130, and potential safety hazards are avoided. Through the reasonable arrangement of 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 safety of the whole electric water heater 100 can be ensured.
The charging module 130 includes a charger 131 and a charger control circuit 132, and the charger 131 and the charger control circuit 132 are electrically connected. In one embodiment, the charger 131 and the charger control circuit 132 may be arranged side by side to form a charging module 130 in a block shape and located at the side end of the battery module 120. In another embodiment, if the thickness of the charger 131 and the charger control circuit 132 in the second direction B-B is greater than the thickness of the battery module 120 in the second direction B-B, the charger 131 and the charger control circuit 132 may be arranged at intervals in 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 actual conditions, so as to minimize the volume of the electric water heater 100 and achieve the safety of the whole electric water heater 100.
In order to realize the control among 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 configured to collect relevant parameters and realize the work control among the modules of the electric water heater 100. The control module 190 is disposed in the accommodating zone 150, and a water and electricity isolation plate 160 is disposed between the control module 190 and the heating module 140. The water and electricity isolating plate 160 separates the control module 190 from the heating module 140, and when water leakage occurs in the heating module 140, the water and electricity isolating 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 close to 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 prevent the water leakage from 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 at the horizontal direction of the heating module 140, i.e., at 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 influence of the water leakage from the heating module 140 on 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 may be interacted with by a user. The display control panel 1111 obtains an operation instruction of a user and transmits the operation instruction to the control module 190, so as to control the modules of the electric water heater 100. The display control panel 1111 may also display the operation status 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 a certain module in the electric water heater 100 is abnormal, 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, when the charging module 130 is abnormal, the first metal shell 171 plays a role in protection and isolation, the influence on other modules is avoided, the electric water heater 100 is safer in whole, and the maintenance of the electric water heater 100 is facilitated; of course, the first metal housing 171 may also protect the internal charging module 130 when other modules are abnormal. The charger 131 and the charger control circuit 132 in the charging module 130 may be integrally wrapped by the first metal housing 171. Or the charger 131 and the charger control circuit 132 may be independently wrapped by the first metal case 171 to independently protect the charger 131 and the charger control circuit 132, respectively, from affecting each other when an abnormality occurs.
Further, as shown in fig. 3, the battery module 120 is wrapped by the second metal housing 172, and the second metal housing 172 has explosion-proof and flame-retardant capabilities, when the battery module 120 is abnormal, the second metal housing 172 plays a role in protection and isolation, so as to prevent other modules from being affected, so that the electric water heater 100 is safer in whole, and is also beneficial to maintenance of the electric water heater 100; of course, the second metal case 172 may also protect the battery module 120 therein when other modules are abnormal.
Specifically, as shown in fig. 3, the first metal housing 171 and the second metal housing 172 may be integrally provided, but the first metal housing 171 and the second metal housing 172 may also be separately provided, and this is not limited herein.
In one embodiment, as shown in fig. 1, the heating module 140 includes a water inlet tube 141, a water heating cup 142 and a water outlet tube 143 connected in sequence, and the water inlet tube 141 and the water outlet tube 143 are inserted into the housing 110. The inflow water flows into the heating cup 142 through the inlet pipe 141, and flows out through the outlet pipe 143 after being heated by the heating cup 142.
In one embodiment, as shown in fig. 1, the electric water heater 100 is an instant electric water heater 100, the heating module 140 is powered by the mains power supply terminal, and when the output power of the mains power supply terminal does not meet the usage requirement, the battery module 120 simultaneously provides power for the heating module 140 to meet the usage requirement of the heating module 140.
In the prior art, for places already occupied, if a special line is not pulled, the power consumption cannot meet the power consumption requirement of the instant electric water heater 100, and the installation space is limited, so that the water storage type electric water heater 100 with a large volume cannot be installed. The electric water heater 100 in this embodiment is powered by the battery module 120 and the commercial power supply terminal, and needs no special line, and only needs the conventional power supply requirement, and can be installed in the place where the electric water heater is already installed, and the electric water heater 100 using the battery module 120 is miniaturized, and the installation space is not limited. In addition, compared to the water storage type electric water heater 100, the instant electric water heater 100 is not easy to generate scale and bacteria.
Certainly, in other embodiments, the electric water heater 100 may also 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 the user to use, and improve the user experience.
In an embodiment, the charging module 130 is a fast charging module 130, and since the fast charging module 130 is adopted, the capacity of the battery module 120 can be reduced, and only a small number of users, such as 1-2 users, need to be ensured, so that the size, weight and cost of the battery module 120 can be reduced, and further the miniaturization of the electric water heater 100 product is realized. Moreover, because the fast charging module 130 has high charging efficiency and generates more heat, the charging module 130 is difficult to dissipate heat, and the heat storage module absorbs the heat of the charging module 130, the heat dissipation of the charging module 130 can be effectively accelerated, the adverse effect of the heat generated by the charging module 130 on the work of the charging module 130 is avoided, and the normal work of other modules is prevented from being influenced by the rise of the internal temperature of the water heater.
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 of the battery module 120 is 6kW or less, for example, 6kW, 5kW, or 3kW or the like. When the energy of the battery module 120 is 3kW · h, the battery module 120 can continuously operate for 30min under the condition that the battery module 120 maintains the highest output power of 6kW, so as to meet the use requirements of a small number of users, for example, 1 to 2 users. The battery module 120 having an energy of 3kW · h or less has a small volume, so that the volume, weight, and cost of the battery module 120 can be reduced, thereby realizing miniaturization of the electric water heater 100. Specifically, the capacity of the battery module 120 is 30AH or less, for example, 30AH, 25AH, 20AH, and the like. In one embodiment, when the battery module 120 has a capacity of 25AH, the volume of the electric water heater 100 using 25AH can be below 45L, while the volume of the conventional electric water heater 100 requires at least 80L. Specifically, the output voltage of the battery module 120 is 126V or less, for example, 126V, 100V, 90V, 80V, etc., which satisfies the use requirement.
It should be noted that the battery module 120 is a ternary lithium battery, which has the characteristics of high rate 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 the electric water heater 100 can be miniaturized. In other embodiments, the battery module 120 may also 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 greatest extent.
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, a large amount of heat is generated during the charging process. The electric water heater 100 further includes a heat dissipating member, and the heat dissipating member is disposed corresponding to the charging module 130. In one embodiment, as shown in fig. 1 and 3, the heat dissipating component includes a first louver 1711 and a second louver 116. The first metal housing 171 is provided with a first heat dissipating hole 1711, the housing 110 is provided with a second heat dissipating hole 116, and the first heat dissipating hole 1711 and the second heat dissipating hole 116 are disposed opposite to each other. Because the first metal housing 171 wraps the outside of the charging module 130, the heat generated by the charging module 130 can be dissipated from the first heat dissipation hole 1711 and the second heat dissipation hole 116, so that the temperature of the charging module 130 is reduced, and the influence of the overhigh temperature on the normal operation of the charging module is avoided. It should be noted that the first heat dissipation hole 1711 and the second heat dissipation hole 116 are correspondingly disposed, the first heat dissipation hole 1711 is disposed on one side of the first metal housing 171 close to the housing 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 certainly, 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 is not transferred to other modules of the electric water heater 100, and normal operation of other modules is not affected.
It should be noted that, as shown in fig. 1 and fig. 3, the charging module 130 includes a charger 131 and a charger control circuit 132, 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, and is not limited herein.
In other embodiments, the heat dissipating member 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 case and a phase change material filled in the case, and the phase change material may absorb heat of the charging module 130, but does not raise an excessive temperature and does not easily transfer the heat to other modules. The heat absorbing member is disposed adjacent to the charging module 130, and may be located inside or outside the first metal housing 171, and preferably, the heat absorbing member is located at a side portion of the charging module 130 close to the outer case 110, i.e., the heat absorbing member is located far away from other modules. In particular, the heat absorbing member may be rectangular parallelepiped.
Of course, in other embodiments, the heat dissipating member may include the first louvers 1711, the second louvers 116, and the heat absorbing member. Preferably, the first heat dissipating hole 1711 and the heat absorbing member are disposed on one side of the charging module 130 close to the housing 110, and the first heat dissipating hole 1711, the second heat dissipating hole 116 and the heat absorbing member are disposed correspondingly. The heat absorbing member 116 is attached to the sidewall of the charging module, and the heat absorbing member can also dissipate heat through the first heat dissipating hole 1711 and the second heat dissipating 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 performance and the use of the battery module 120 are greatly affected by the heat, as shown in fig. 1, in order to avoid the influence of the charging module 130 on 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 insulation member 180 may be made of heat insulation materials such as dellon, etc., and blocks heat of the charging module 130 from being transferred to the battery module 120, so as to ensure that heat generated by the operation of the charging module 130 is not transferred to the battery module 120, and make the overall design of the electric water heater 100 safer. Specifically, the heat insulator 180 is located between the charging module 130 and the battery module 120, the heat insulator 180 completely covers a side of the charging module 130 close to the battery module 120, and the heat insulator 180 has a layered or plate-shaped structure having a certain thickness in order to reduce the volume. The thickness of the heat insulation member 180 from the charging module 130 to the battery module 120 can be adjusted according to actual conditions, so as to avoid the influence of the heat of the charging module 130 on 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, and the phase change material can absorb heat of the charging module 130, but does not raise the temperature too much and is not easy to transfer the heat to the battery module 120. Therefore, the heat insulation member 180 not only facilitates the heat dissipation of the charging module 130, but also prevents the 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 insulation member 180 at one side of the charging module 130 close to the battery module 120 and arranging the heat dissipation member at one side close to the housing 110, on one hand, the heat of the charging module 130 is prevented from being transferred to the battery module 120, on the other hand, the heat dissipation of the charging module 130 is accelerated, the temperature of the charging module 130 is effectively reduced, and the overall design of the electric water heater 100 is safer; further, due to the combined heat insulating and dissipating function of the heat insulating member 180 and the heat dissipating member, the internal structure of the electric water heater 100 can be designed to be more compact, thereby achieving miniaturization of the electric water heater 100.
The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
