[0031] To more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0032] In related technologies, the electronic control box has a relatively complex control system, so the power lines, electronic control lines and other lines on the electronic control box are relatively redundant. The messy lines are likely to affect the related components or modules inside the electronic control box, which not only makes the production and assembly cumbersome, but also brings certain difficulties to after-sales maintenance.

[0033] In view of the above situation, in the first aspect, please refer to Figures 1 - 3 , the present application proposes an electronic control box 1, including a box body 10, an electronic control component 20 and a connection component (not shown in the figure). The electronic control component 20 is arranged inside the box body 10. The connection component can be used to connect the electronic control component 20 inside the box body 10, and the connection component can also be used to connect the electronic control component 20 and electrical components outside the electronic control box 1. The electronic control box 1 can be installed in an electrical device, and the electrical device can be a water heater, a refrigerator or an air conditioner, etc. In the following, the electrical device is taken as a water heater as an example.

[0034] A wire groove 11 and a first placement groove 12 are formed on the box body 10. One end of the wire groove 11 communicates with the first placement groove 12, and the other end of the wire groove 11 communicates with the outside of the box body 10. The wire groove 11 can be used for an external wire to extend in; the connection component includes a first connector, and the first connector is arranged in the first placement groove 12. The first connector has a first interface and a second interface. The first interface is electrically connected to the electronic control component 20, and the second interface corresponds to the wire groove 11. The first interface can be used to be electrically connected to an external wire.

[0035] Specifically, the first placement groove 12 provides a setting basis and an installation space 32 for the first connector. The first connector plays a role in transferring for the electronic control component 20 inside the box body 10, so as to facilitate the electrical connection between the electronic control component 20 inside the box body 10 and the electrical components outside the box body 10. Among them, the first placement groove 12 can be located inside the box body 10 or outside the box body 10, and no specific limitation is made here.

[0036] It should be noted that in the embodiment of the present application, by providing a wire groove 11 for wire routing on the box body 10, a groove body specifically for accommodating connection wires is provided on the electric control box 1, so as to reduce the probability of external connection wires being randomly distributed on the electric control box 1, thereby improving the wire routing layout of the electric control box 1; at the same time, a first placement groove 12 for placing the first connector is provided on the box body 10, so that the first connector has a fixed installation position, which facilitates the user to perform subsequent wiring operations and also reduces the relative movement between the first connector and the box body 10, that is, reduces the shaking and displacement of the first connector in the box body 10.

[0037] Please refer to Figure 1 , in some embodiments of the present application, the wire groove 11 and the first placement groove 12 are both located on the outer side wall of the box body 10. That is to say, the first connector is also located outside the box body 10, so as to reduce the wire distribution inside the box body 10, so that most of the space inside the box body 10 can be provided for the electric control component 20, and at the same time reduce the heat generation inside the box body 10.

[0038] Furthermore, as Figure 1 shown, the box body 10 has a receiving cavity (not shown in the figure) and a wiring hole 13 communicating with the receiving cavity. The electric control component 20 is arranged in the receiving cavity, and the first connector and the wire for connecting the external to the electric control component 20 are both located outside the receiving cavity.

[0039] The connection component further includes a patch cord, which is used to connect the electric control component 20 to the first connector and the external electrical component. One end of the patch cord is electrically connected to the electric control component 20, and the other end of the patch cord extends out of the receiving cavity through the wiring hole 13 and is electrically connected to the first connector. That is, the first interface is electrically connected to the electric control component 20 in the box body 10 through the patch cord to form a current path. Among them, the setting of the wiring hole 13 makes the position where the patch cord extends out of the receiving cavity fixed, so as to reduce the random distribution of the patch cord in the box body 10.

[0040] Please continue to refer to Figure 1 and Figure 3 , in some embodiments of the present application, the box body 10 includes a connected first side plate 14 and a second side plate 15. The wire groove 11 and the first placement groove 12 are both arranged on the first side plate 14; the electric control component 20 includes a driving module (not shown in the figure) and a control module 21, and the driving module is electrically connected to the control module 21. The driving module is arranged on the first side plate 14 and is electrically connected to the first connector, and the control module 21 is arranged on the second side plate 15.

[0041] It can be understood that the driving module and the control module 21 are separately and independently arranged on two different side panels of the box body 10, which can reduce the mutual interference between the driving module and the control module 21. At the same time, the first side panel 14 is connected to the second side panel 15, which can make the spacing distance between the driving module and the control module 21 smaller, making it easier for the driving module to be electrically connected to the control module 21 through electrical connecting lines.

[0042] For further information, please see Figure 1 and Figure 3 In some embodiments of the present application, a second mounting groove 16 is provided on the second side panel 15, and the connecting component also includes a second connector arranged in the second mounting groove 16, the second connector is electrically connected to the control module 21, and the second connector is also used to electrically connect to an external wire.

[0043] Specifically, the control module 21 is electrically connected to an external power source or device through the second connector, and the second mounting groove 16 provides a setting base and an installation space 32 for the second connector, which not only makes the installation of the second connector more convenient, but also fixes the installation position of the second connector, which is beneficial to the user's subsequent wiring operations.

[0044] For further information, see Figure 4 In some embodiments of the present application, the first side plate 14 and the second side plate 15 are arranged at an angle, and a placement space 141 is defined between the first side plate 14 and the second side plate 15, thereby making the structure of the electric control box 1 more compact, which is conducive to reducing the volume of the water heater on which the electric control box 1 is installed. The first side plate 14 and the second side plate 15 can be connected by screwing, clamping, welding or bonding.

[0045] A first sub-box 17 is provided on a side of the first side plate 14 facing the placement space 141. The first sub-box 17 has a first installation cavity and a first through hole 171 connected to the first installation cavity. The driving module is located in the first installation cavity. The first through hole 171 is located on the side of the first sub-box 17 facing the placement space 141, that is, the first through hole 171 is located on the side of the first sub-box 17 away from the first side plate 14. The first through hole 171 faces the placement space 141, which facilitates the driving module in the first installation cavity to be electrically connected to the electrical device located in the placement space 141, that is, the wires on the electrical device can be directly extended into the first through hole 171 to be electrically connected to the driving module. On the basis of making the structure of the water heater more compact, the length of the wires of the electrical device can be shortened, thereby improving the disorderly distribution of the wires on the electric control box 1.

[0046] Specifically, the first installation cavity provides installation space and protection for the driving module, and the first through hole 171 is used to allow the electrical connection wire in the electric control box 1 to extend out of the first installation cavity, or the first through hole 171 is used to allow the external wire to extend into the first installation cavity, so that the driving module is electrically connected to the electrical device outside the electric control box 1. In this embodiment, there is no specific limitation on the number of the first through holes 171, and one or more first through holes 171 may be provided.

[0047] In some embodiments, Figure 1 and Figure 4 As shown, a side of the second side plate 15 away from the placement space 141 is provided with a surrounding plate 19, and the surrounding plate 19 and the second side plate 15 are surrounded to form a second installation cavity, and the control module 21 (such as Figure 3 As shown in the figure, the second installation cavity is located in the second installation cavity, which provides installation space and protection for the control module 21. The second installation cavity is connected to the first installation cavity, thereby facilitating the wiring connection between the control module 21 and the drive module.

[0048] Specifically, the second side plate 15 and / or the enclosure 19 are provided with a second through hole 191, and the second through hole 191 is used for allowing an external wire to extend into the second installation cavity, so that the control module 21 is electrically connected to the electrical components outside the electric control box 1. Among them, one or more second through holes 191 can be provided. For example, if there is one second through hole 191, the second through hole 191 is provided on the second side plate 15, and the second through hole 191 faces the placement space 141; for example, if there are two second through holes 191, the two second through holes 191 are provided on opposite sides of the outer periphery of the enclosure 19. When the second through holes 191 are provided on the outer periphery of the enclosure 19, the electrical components provided in the placement space 141 can extend from the peripheral side of the enclosure 19 into the second installation cavity.

[0049] For further information, see Figure 4 In some embodiments of the present application, a wire-passing rubber ring 18 is provided on the first sub-box 17, and the wire-passing rubber ring 18 is located at the first through hole 171. The first installation cavity is connected to the outside through the wire-passing rubber ring 18. It can be understood that the wire-passing rubber ring 18 has an inner groove, and the wire-passing rubber ring 18 can cover the exposed cables, wires or other wires in the inner groove, providing a continuous and safe passage for the wires to prevent the wires from being directly exposed and causing various safety hazards. Similarly, it can be known that a wire-passing rubber ring 18 can also be provided at the second through hole 191 to protect the wires passing through the second through hole 191.

[0050] Second, see Figure 5, The embodiment of the present application further provides a water heater, which includes a main body 30, an electrical component 40, and the electric control box 1 described in any of the above embodiments. The electric control box 1 and the electrical component 40 are arranged in the main body 30. The electrical component 40 includes a wire, and the wire extends into the wire slot 11 and is electrically connected to the second interface of the first connector.

[0051] Specifically, according to the structure of the electric control box 1, the electric control box 1 can be installed on the side of the main body 30 to facilitate avoiding other components in the main body 30. Since the electrical component 40 needs to be electrically connected to the electric control component 20 in the electric control box 1, the electrical component 40 can be arranged adjacent to the electric control box 1, so that the distance from the electrical component 40 to the electric control component 20 is small, which is convenient for the electrical connection between the electrical component 40 and the electric control component 20. Among them, the electrical component 40 can include electrical components such as a compressor, a motor, a pressure switch, and an electronic expansion valve.

[0052] It should be noted that the wire on the electrical component 40 can extend through the wire slot 11 and be electrically connected to the first connector at the position of the first placement groove 12, so that the extension of the wire in the water heater is more regular, that is, the relative position of the wire and the electric control box 1 is fixed, thereby reducing the probability of the wire being randomly distributed in the water heater and improving the wire routing layout in the water heater.

[0053] Please refer to Figure 5 , In some embodiments of the present application, the main body 30 includes a partition 31. The partition 31 is connected to the electric control box 1 and defines an installation space 32. The electrical component 40 is located in the installation space 32, so that the position of the electrical component 40 is closer to the electric control box 1, which is beneficial to the wire connection between the two.

[0054] When the water heater is in the normal placement state, the electric control box 1 is located above the installation space 32. That is to say, the electric control box 1 is located above the electrical component 40, and the partition 31 is located on the side of the electrical component 40. A fixing member 33 is arranged on the side of the partition 31 facing the installation space 32. The wire on the electrical component 40 extends upward to connect to the electric control box 1. At this time, the wire can be fixed to the partition 31 through the fixing member 33 on the partition 31, so that the wires in the installation space 32 can be bundled on the first side plate 14, thereby reducing the random distribution of the wires in the installation space 32. Among them, the fixing member 33 can be an iron bundle strip, a buckle, a tie strap, etc.

[0055] Furthermore, please refer to Figure 6 , In some embodiments of the present application, the water heater further includes a control valve 41 connected to the electrical component 40. The control valve 41 is located in the installation space 32 and is arranged between the electric control box 1 and the electrical component 40. The control valve 41 is electrically connected to the electric control component 20 of the electric control box 1.

[0056] Specifically, the installation position of the control valve 41 is closer to the electric control box 1, that is, the distance between the control valve 41 and the electric control box 1 is shortened, thereby reducing the wire length between the control valve 41 and the electric control box 1, and further reducing the redundant wires in the installation space 32. Among them, the electrical connection wire of the control valve 41 can extend into the second installation cavity from the second through hole 191 to be electrically connected to the internal control module 21.
