Detailed implementation manners

[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] The present application provides an electric control box and a water heater to solve the problem in the related art that each side plate of the box body is generally connected by threaded parts such as tapping screws. When disassembling and assembling the threaded parts, the threaded parts will have hard friction with the side plate of the box body, resulting in the threaded parts falling off iron filings. The iron filings falling on the electric control board may cause a short circuit and burnout of the electric control board.

[0032] In the first aspect, the present application provides an electric control box, as Figures 1 to 6 shown, the electric control box includes a main body framework 10, an electric control board 20 and a first side plate 30.

[0033] Among them, the electronic control board 20 is installed on the main body structure 10, and a first mounting hole 31 is provided on the first side plate 30. It should be noted that the electronic control box can be installed in an electrical device. The electronic control box can be used to control the opening and closing of the electrical device, realizing functions such as circuit protection and circuit monitoring, so as to improve the safety and reliability of the electrical device. The electrical device can be a water heater, a refrigerator, an air conditioner, etc.; the main body structure 10 is used to provide an installation space and support for devices such as the electronic control board 20 and the first side plate 30; the electronic control board 20 can be a circuit board integrated with multiple electronic components. The circuit board can be a single-sided board, a double-sided board or a multi-layer board. The present application does not make specific limitations on the type, model and size of the circuit board, etc. The first side plate 30 is one of the side plates of the box body of the electronic control box. The first side plate 30 is connected to the main body structure through a first mounting member passing through the first mounting hole 31, so as to realize the installation on the main body structure 10. The first mounting hole 31 can be a threaded hole, and the first mounting member can be a threaded connecting member such as a screw or a bolt.

[0034] Specifically, the electronic control box further includes a first blocking structure 51. The first blocking structure 51 is located between the first mounting hole 31 and the electronic control board 20, and the first blocking structure 51 is opposite to the first mounting hole 31 in position. It should be noted that the first blocking structure 51 can block the electronic control board 20. When the first mounting member passes through the first mounting hole 31, the debris falling from the first mounting member, the first side plate 30 and the main body structure 10 due to friction and scraping will be intercepted by the first blocking structure 51 after passing through the first mounting hole 31. Thus, it can prevent these debris from falling onto the electronic control board 20 and causing a short circuit and burning of the electronic control board 20, and further improve the safety performance of the electronic control box.

[0035] In some embodiments of the present application, the first blocking structure 51 includes a receiving groove 511 provided on the main body structure 10 (such as Figure 5 ), the receiving groove 511 is opposite to the first mounting hole 31 in position, and the notch of the receiving groove 511 faces the first mounting hole 31. It can be understood that when the first mounting member passes through the first mounting hole 31, the falling debris will fall into the receiving groove 511 and be temporarily stored by the receiving groove 511, so as to prevent these debris from falling onto the electronic control board 20 and causing a short circuit and burning of the electronic control board 20. And the receiving groove 511 can be formed by digging a groove on the main body structure 10, and the receiving groove 511 can also be formed when die-casting the main body structure 10. Without adding additional structural parts in the electronic control box, the debris falling from the first mounting hole 31 can be intercepted, which can reduce the number of components of the electronic control box and lower the production cost of the electronic control box.

[0036] Such as Figures 1 to 4As shown, in some embodiments of the present application, the electronic control box further includes a second side plate 40, which is disposed at an angle with the first side plate 30, and a receiving space 61 is defined between the second side plate 40 and the first side plate 30. It should be noted that the angle formed by the second side plate 40 and the first side plate 30 can be 90 degrees. Of course, in other embodiments, the angle formed by the second side plate 40 and the first side plate 30 can also be 30 degrees, 60 degrees, 120 degrees or other degrees. It should be noted that in the embodiments of the present application, by disposing the second side plate 40 at an angle with the first side plate 30, the first side plate 30 and the second side plate 40 can support each other, and the placement space can provide a receiving and installation space for other electrical components in the electronic control box, which is beneficial to the miniaturization of the installation of the electronic control box.

[0037] Wherein, a first connection hole 41 is provided on the second side plate 40, a first blocking structure 51 is located between the first connection hole 41 and the electronic control board 20, and the first blocking structure 51 is opposite to the first connection hole 41 in position. It should be noted that the second side plate 40 is one of the side plates of the box body of the electronic control box. The second side plate 40 is connected to the main body structure through a first connecting member passing through the first connection hole 41, so as to realize the installation on the main body frame 10. The first connection hole 41 can be a threaded hole, and the first connecting member can be a threaded connecting member such as a screw or a bolt. When the first connecting member passes through the first connection hole 41, the debris falling from the first connecting member, the second side plate 40 and the main body frame 10 due to friction and rubbing will be intercepted by the first blocking structure 51 after passing through the first connection hole 41, which can prevent these debris from falling onto the electronic control board 20 and causing a short circuit and burning of the electronic control board 20, thereby further improving the safety performance of the electronic control box.

[0038] In one embodiment, the first connection hole 41 is opposite to the first mounting hole 31 in position, and the first connection hole 41 and the first mounting hole 31 are arranged along the axial direction of the first connection hole 41 and the first mounting hole 31. It should be noted that the axial direction of the first connection hole 41 refers to the extending direction of the axis line of the first connection hole 41, and the axial direction of the first mounting hole 31 refers to the extending direction of the axis line of the first mounting hole 31. When installing the first side plate 30 and the second side plate 40, the first mounting member or the first mounting member (in this embodiment, the first mounting member and the first connecting member are the same object) can pass through the first connection hole 41 and the first mounting hole 31, so as to realize the installation of the first side plate 30 and the second side plate 40 at the same time, making the installation of the first side plate 30 and the second side plate 40 more convenient and fast, and the volume of the first blocking structure 51 can be reduced. On the basis that the volume of the first blocking structure 51 is small, the debris falling from the first connection hole 41 and the first mounting hole 31 can still be intercepted. Further, the axis line of the first mounting hole 31 can coincide with the axis line of the first connection hole 41, so that the first mounting hole 31 and the first connection hole 41 are coaxially arranged, making it smoother for the first mounting member or the first mounting member to pass through the first mounting hole 31 and the first connection hole 41.

[0039] As Figure 2 and Figure 3 shown, in one embodiment, the second side plate 40 includes a connecting portion 42. The first connection hole 41 is located in the connecting portion 42. The connecting portion 42 is located on the side of the first side plate 30 away from the electronic control board 20. A part of the first side plate 30 is clamped between the connecting portion 42 and the main body structure 10. It can be understood that a limiting space is formed between the connecting portion 42 and the main body structure, which can provide limitation for the first side plate 30, making the installation of the first side plate 30 more stable and preventing the first side plate 30 from detaching from the main body structure.

[0040] Further, a positioning groove 33 is provided on the first side plate 30, and the connecting portion 42 is accommodated in the positioning groove 33. Using the positioning groove 33 to provide an accommodation space for the connecting portion 42 can reduce the overall thickness when the connecting portion 42 and the first side plate 30 are stacked, thereby reducing the overall volume of the electronic control box; in addition, when installing the second side plate 40, inserting the connecting portion 42 of the second side plate 40 into the positioning groove 33 can realize the positioning of the second side plate 40, making the positioning installation of the second side plate 40 more convenient.

[0041] As Figures 4 to 6As shown, in some embodiments of the present application, a second mounting hole 32 is provided on the first side plate 30, and the second mounting hole 32 is located laterally of the first mounting hole 31. It should be noted that the first side plate 30 can also be connected to the main body structure by a second mounting member passing through the second mounting hole 32, making the installation of the first side plate 30 more stable. The second mounting hole 32 can be a threaded hole, and the second mounting member can be a threaded connector such as a screw or a bolt.

[0042] Wherein, a second blocking structure 52 is further provided on the main body framework 10. The second blocking structure 52 is located between the second mounting hole 32 and the electronic control board 20, and the second blocking structure 52 is opposite to the second mounting hole 32 in position. It should be noted that the second blocking structure 52 can block the electronic control board 20. When the second mounting member passes through the second mounting hole 32, after the debris falling from the second mounting member, the first side plate 30 and the main body framework 10 due to friction and rubbing passes through the second mounting hole 32, these debris will be intercepted by the second blocking structure 52, which can prevent these debris from falling onto the electronic control board 20 and causing a short circuit and burning of the electronic control board 20.

[0043] Furthermore, two second mounting holes 32 are provided, and the two second mounting holes 32 are respectively located on opposite sides of the first mounting hole 31, making the installation of the first side plate 30 more stable. Even further, the first mounting hole 31 is provided in the middle near the upper end of the first side plate 30, and the second mounting hole 32 is provided near the edge of the upper end of the first side plate 30, making the installation of the first side plate 30 more stable.

[0044] In some embodiments, a mounting bracket 62 is mounted on the main body framework 10. A second connection hole 621 opposite to the second mounting hole 32 in position is provided on the mounting bracket 62. The first side plate 30 is connected to the mounting bracket 62. The second blocking structure 52 is located between the second connection hole 621 and the electronic control board 20, and the second blocking structure 52 is opposite to the second connection hole 621 in position. It can be understood that the second connection hole 621 can be a threaded hole. When installing the first side plate 30, the second mounting member can pass through the second mounting hole 32 and the second connection hole 621 in sequence to realize the connection between the first side plate 30 and the mounting bracket 62, and further realize the connection between the first side plate 30 and the main body framework 10. Among them, the mounting bracket 62 can be connected to the main body framework 10 by welding, snap connection, threaded connection, bonding or other means.

[0045] In some embodiments, an installation groove 622 is provided on the installation bracket 62. The second connection hole 621 communicates with the installation groove 622, and the second blocking structure 52 is located in the installation groove 622. The installation groove 622 can be used to provide an installation space and limit for the second blocking structure 52, preventing the second blocking structure 52 from moving relative to the main body frame 10. Among them, the second blocking structure 52 can be connected to the installation bracket 62 by bonding, welding, snap connection, threaded connection or other means.

[0046] In some embodiments, the second blocking structure 52 includes a sponge block 521. It can be understood that the sponge block 521 has a porous and fluffy structure. When debris falls onto the sponge block 521, it will be adsorbed on the sponge block 521, thereby effectively intercepting the debris and preventing these debris from falling onto the electronic control board 20 and causing a short circuit and burnout of the electronic control board 20.

[0047] In some embodiments, as Figure 2 and Figure 4 shown, the main body frame 10 has a receiving cavity 11, and the electronic control board 20 is located in the receiving cavity 11, using the receiving cavity 11 to provide an installation space and protection for the electronic control board 20; among them, one side of the receiving cavity 11 facing the first side plate 30 is a first opening, and a second opening opposite to the position of the first opening is provided on the first side plate 30. The electronic control box further includes a cover plate 63, and the cover plate 63 is covered on the second opening and is used to control the opening and closing of the second opening, so that it is convenient to repair the electronic control board 20 through the second opening.

[0048] In some embodiments, the electronic control box further includes a first sealing member 64, and the first sealing member 64 is located between the main body frame 10 and the first side plate 30 and is used to achieve the sealing performance at the connection between the main body frame 10 and the first side plate 30. The first sealing member 64 can be made of rubber, plastic or metal.

[0049] In some embodiments, the electronic control box further includes a second sealing member 65, and the second sealing member 65 is located between the cover plate 63 and the first side plate 30 and is used to achieve the sealing performance at the connection between the first side plate 30 and the cover plate 63, and can block the connection portion 42 and the positioning groove 33. The second sealing member 65 can be made of rubber, plastic or metal.
