[0040] The technical solution of the present application will be described below in conjunction with the drawings in the implementation modes of the present application. Obviously, the described implementation modes are only part of the implementation modes of the present application, rather than all the implementation modes.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0043] In a portable electric water heater, the heating rod needs to be inserted into the water tank to heat the water when in use, and the electric heating controller is electrically connected to the heating rod to control the heating of the heating rod. At present, according to different usage scenarios, the electric heating controller in the related art usually has two installation methods. The first is that the electric heating controller is connected to the heating rod as a whole, that is, the electric heating controller is installed with the water tank, and the second is that the electric heating controller is hung on the wall, and the electric heating controller is connected to the heating rod through a cable. In the first installation method, the electric heating controller is generally located on the side of the water tank, which occupies a large space and is difficult to install when the space around the water tank is limited; in the second installation method, the electric heating controller needs to occupy the wall space and cannot be applied to walls that are difficult to punch and hang, such as ceramic tile walls. At present, the above two installation methods are incompatible, so the electric heating controller of the first installation method cannot be applied to the scene of the second installation method, and vice versa, the electric heating controller of the second installation method cannot be applied to the scene of the first installation method, resulting in low adaptability of the electric heating controller.

[0044] In view of this, the present application provides an electric heating controller and an electric heater capable of improving adaptability. The electric heating controller includes a bracket and a host. The bracket is provided with a first mounting position and a second mounting position, the first mounting position is configured for the heating rod to be detachably mounted on the bracket, and the second mounting position is configured for the bracket to be detachably mounted on a base surface. The host is detachably connected to the bracket, the host is provided with a port, the port is configured to be electrically connected to the cable of the heating rod, and the host is configured to control the working state of the heating rod.

[0045] The electric heating controller provided by the present application is in an integrated installation state when the bracket is installed on the heating rod through the first installation position; the electric heating controller is in a split installation state when the bracket is separated from the heating rod or the main unit is separated from the bracket. The user can select the integrated installation state or the split installation state according to the usage scenario when using it. When the electric heating controller needs to be separated from the heating rod, the split installation state is selected, that is, the bracket is separated from the heating rod, and the heating rod and the main unit are connected by a cable. The bracket can install the main unit on a base surface such as a wall through the second installation position, thereby avoiding occupying a large space and facilitating installation when the space around the water tank is limited, or The main unit and the bracket can also be separated and the main unit can be placed elsewhere alone. Since the volume and weight of the single main unit are smaller than the overall structure composed of the main unit and the bracket, the occupied space can be reduced and the packaging and transportation of the bracket and the main unit can be facilitated. When the electric heating controller needs to be installed integrally with the heating rod, an integrated installation state is selected, that is, the bracket is installed with the heating rod through the first installation position, so that the electric heating controller and the heating rod are connected as one and directly installed on the water tank, thereby not occupying wall space or overcoming scenarios such as walls that are difficult to punch holes for hanging. Therefore, the electric heating controller provided in the present application is compatible with three installation methods, which is easier to adapt to a variety of scenarios and improves adaptability.

[0046] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0047] See also Figure 1 and Figure 2 In the embodiment of the present application, an electric heating controller 100 and an electric heater 200 are provided. The electric heater 200 includes the electric heating controller 100, a heating rod 201 and a cable 202. The heating rod 201 is used to be inserted into a water tank 300 to heat the water in the water tank 300. The heating rod 201 is electrically connected to the electric heating controller 100 through the cable 202. The electric heating controller 100 is used to control the working state of the heating rod 201, such as controlling the opening, closing, heating, cooling or heat preservation of the heating rod 201, so as to adjust the water temperature in the water tank 300. As an exemplary example, the electric heater 200 and the water tank 300 are portable and can be used in outdoor, RV or home scenes. The electric heating controller 100 can be connected to a photovoltaic system to control the heating of the heating rod 201 through photovoltaic power generation. The electric heating controller 100 can also allow users to set the heating temperature, display the water temperature or have functions such as home energy system communication.

[0048] In some embodiments, the electric heating controller 100 includes a bracket 10 and a host 20. The host 20 is provided with a port 21 (see Figure 7), port 21 is used to plug the end of cable 202, so that host 20 is electrically connected to heating rod 201, and host 20 is used to control the working state of heating rod 201. Bracket 10 can be installed on the outer surface of water tank 300, or installed on a base surface 400. Host 20 can be installed on bracket 10, or removed from bracket 10. Heating rod 201 can be installed on bracket 10, or removed from bracket 10. As an illustrative example, base surface 400 can be a wall, a ceiling, or a wall of a cabinet, etc.

[0049] The electric heating controller 100 has an integrated installation state and a split installation state, which can be selected according to the actual use scenario:

[0050] When the electric heating controller 100 needs to be separated from the heating rod 201, the split installation state is selected, the bracket 10 is separated from the heating rod 201, the bracket 10 is installed on the base surface 400, and the main unit 20 is installed on the bracket 10, so that the main unit 20 does not need to be installed on the water tank 300, thereby avoiding the water tank 300 and the electric heating controller 100 being combined to occupy too much space, thereby facilitating installation when the space around the water tank 300 is limited.

[0051] Alternatively, in the split installation state, the main unit 20 and the bracket 10 can also be separated, and the main unit 20 can be placed in other positions alone, so that the main unit 20 does not need to be installed on the water tank 300 or the base surface 400. Since the volume and weight of the single main unit 20 are relatively small compared to the overall structure composed of the main unit 20 and the bracket 10, the occupied space can be reduced, and the packaging and transportation of the main unit 20 and the bracket 10 can also be facilitated;

[0052] When the electric heating controller 100 needs to be installed integrally with the heating rod 201, the integrated installation state is selected, the bracket 10 is installed with the heating rod 201, and the host 20 is installed on the bracket 10, so that the electric heating controller 100 is installed on the water tank 300, thereby not occupying the space on the base surface 400 or overcoming the base surface 400 that is difficult to punch and hang. In summary, the electric heating controller 100 is compatible with three installation methods, which is more convenient to adapt to a variety of practical application scenarios and improves adaptability.

[0053] See also Figures 3 to 7In some embodiments, the host 20 includes a main controller 22 and a radiator 23, the main controller 22 is used to control the working state of the heating rod 201, and the radiator 23 is used to dissipate heat from the main controller 22. One side of the radiator 23 is connected to the main controller 22, and the other side is provided with a plurality of parallel fins 231. The bracket 10 is connected to the host 20 by being detachably connected to the fins 231. Since the bracket 10 does not need to be directly mounted on the main controller 22, there is no need to design a structure for connecting the bracket 10 on the main controller 22, such as opening a hole or a groove, etc., thereby improving the waterproof and dustproof effect of the main controller 22. In addition, since the bracket 10 is connected to the fins 231, the bracket 10 can play a role in auxiliary heat dissipation, thereby improving the heat dissipation efficiency of the radiator 23.

[0054] In some embodiments, the bracket 10 is detachably connected to the two outermost fins 231 of the plurality of fins 231, at least part of the bracket 10 is located on the side of the radiator 23 away from the main controller 22, and there is a gap between the bracket 10 and the fins 231, so that the fins 231 are spaced from the heating rod 201 or the base surface 400, ensuring that an air duct is formed between the fins 231 and the heating rod 201 or the base surface 400 to ensure heat dissipation efficiency. The bracket 10 and the fins 231 can be detachably connected by means of screws, buckles, and other structures.

[0055] In some embodiments, the bracket 10 is provided with a first mounting position 11 and a second mounting position 12, wherein the first mounting position 11 is used to detachably mount the heating rod 201, facilitating assembly and disassembly of the bracket 10 and the heating rod 201. The second mounting position 12 is used to detachably mount the bracket 10 on the base surface 400, facilitating assembly and disassembly of the bracket 10 and the base surface 400.

[0056] In some embodiments, the first mounting position 11 is a circular hole. When the bracket 10 is mounted on the heating rod 201, one end of the heating rod 201 passes through the circular hole, so that the bracket 10 can rotate relative to the heating rod 201 around the axis of the circular hole, so that the electric heating controller 100 can rotate relative to the heating rod 201 and the water tank 300, and then the electric heating controller 100 can change its own placement posture by rotating to avoid other objects in the space, thereby saving space; at the same time, the port 21 can also be rotated to a position convenient for plugging in the cable 202, so as to facilitate wiring operations. Among them, when the bracket 10 is mounted on the heating rod 201, one end of the heating rod 201 passes through the circular hole and can be limited by fasteners such as nuts. By adjusting the limiting tightness of the nut, the bracket 10 can still rotate relative to the heating rod 201 around the axis of the circular hole.

[0057] In some embodiments, the second mounting position 12 is a through hole. When the bracket 10 is mounted on the base surface 400, the bracket 10 further includes a fixing member (not shown), and the fixing member passes through the through hole and the base surface 400 to fix the bracket 10 to the base surface 400. As an exemplary example, the fixing member can be an expansion screw or a nail. It is understandable that in other embodiments, the first mounting position 11 and the second mounting position 12 can also be other structures such as buckles.

[0058] In some embodiments, when the host 20 is mounted on the bracket 10, a receiving cavity 13 is formed between the bracket 10 and the host 20, and the port 21 and the radiator 23 are both located in the receiving cavity 13. The receiving cavity 13 can protect the port 21, the radiator 23 and the cable 202. The bracket 10 is provided with a vent 14, which connects the receiving cavity 13 with the external environment to ensure the heat dissipation effect of the fin 231. When the bracket 10 is mounted on the heating rod 201, the heating rod 201 is partially located in the receiving cavity 13 through the first mounting position 11, and one end of the cable 202 is connected to the port 21, and the other end is connected to the part of the heating rod 201 located in the receiving cavity 13, so that the cable 202 can be stored in the receiving cavity 13, thereby improving safety. The bracket 10 is also provided with a harness port 15. When the bracket 10 is separated from the heating rod 201, the harness port 15 allows the cable 202 to extend out of the receiving cavity 13, so as to allow one end of the cable 202 to be connected to the port 21 and the other end to be connected to the heating rod 201.

[0059] Optionally, since the cable 202 is received in the accommodating cavity 13 when the bracket 10 is mounted on the heating rod 201, the cable 202 does not need to extend out of the accommodating cavity 13 through the harness port 15. In this case, the bracket 10 further includes a blocking member (not shown) for sealing the harness port 15 to protect the port 21. As an illustrative example, the blocking member may be a plug or the like.

[0060] Optionally, the bracket 10 includes a mounting plate 16, a first folding plate 17, and a second folding plate 18. The first mounting position 11 and the second mounting position 12 are provided on the mounting plate 16, so that the bracket 10 is installed on the heating rod 201 or the base surface 400 through the mounting plate 16. The first folding plate 17 and the second folding plate 18 are respectively connected to opposite sides of the mounting plate 16 and are bent toward the host 20 relative to the mounting plate 16. There is a gap between the mounting plate 16 and the host 20. The first folding plate 17 and the second folding plate 18 are each provided with at least one vent 14, so that an air duct with an air inlet and an air outlet relative to each other is formed in the accommodating cavity 13 to ensure the heat dissipation effect of the radiator 23. The first folding plate 17 and the second folding plate 18 are respectively located on opposite sides of the fin 231 along its extension direction, so that the air duct is parallel to the fin 231, so that the airflow in the air duct can flow through the fin 231 more smoothly, increase the contact area between the airflow and the fin 231, and improve the heat dissipation efficiency.

[0061] See also Figure 8and Fig.11 In other embodiments, the bracket 10 includes a mounting plate 161 and two connecting plates 19 disposed on opposite sides of the mounting plate 161. The first mounting position 11 and the second mounting position 12 are disposed on the mounting plate 161, so that the bracket 10 is mounted on the heating rod 201 or the base surface 400 through the mounting plate 161. The two connecting plates 19 are bent relative to the mounting plate 161, and the two connecting plates 19 are connected to the host 20 on the side away from the mounting plate 161, and a gap is provided between the mounting plate 161 and the host 20, so as to form an air duct between the radiator 23 and the mounting plate 161, so as to ensure the heat dissipation effect of the radiator 23. Through the mounting plate 161 and the two connecting plates 19, the bracket 10 can expose the radiator 23 in a larger area on the basis of realizing the installation function, thereby improving the heat dissipation efficiency of the radiator 23.

[0062] Optionally, the electric heating controller 100 further includes a terminal cover 101, which is disposed on the host 20 and covers the port 21 to protect the port 21. The terminal cover 101 is provided with a harness port 15, and the harness port 15 allows the cable 202 to pass through the terminal cover 101, so as to allow one end of the cable 202 to be connected to the port 21 and the other end to be connected to the heating rod 201.

[0063] Optionally, the electric heating controller 100 further includes a wire gathering member 102, which is disposed outside the end housing 101 and around the wire harness port 15, and is used to gather the cables 202 to prevent the cables 202 from being loose. As an exemplary example, the wire gathering member 102 is a cylindrical structure.

[0064] See also Fig.12 and Fig.13 In some other embodiments, the bracket 10 includes a mounting plate 162, a support plate 103 and two connecting plates 104. The first mounting position 11 and the second mounting position 12 are provided on the mounting plate 162, so that the bracket 10 is installed on the heating rod 201 or the base surface 400 through the mounting plate 161. The two connecting plates 104 are provided on opposite sides of the mounting plate 162 and are bent relative to the mounting plate 162. The two connecting plates 104 are connected to the host 20 on the side away from the mounting plate 162, and a gap is provided between the mounting plate 162 and the host 20, so as to form an air duct between the radiator 23 and the mounting plate 162, so as to ensure the heat dissipation effect of the radiator 23. The support plate 103 is connected to one side of the mounting plate 162 between the two connecting plates 104. The support plate 103 is bent relative to the mounting plate 162. The side of the support plate 103 away from the mounting plate 162 is connected to the host 20. The support plate 103 is used to strengthen the connection between the mounting plate 162 and the host 20 to improve the stability between the bracket 10 and the host 20.

[0065] Optionally, the support plate 103 is provided with an air avoidance groove 1031 , which connects the air duct between the radiator 23 and the mounting plate 162 , making the airflow in the air duct smoother and avoiding the support plate 103 from blocking the airflow in the air duct, so as to ensure the heat dissipation efficiency of the radiator 23 .
