[0037] This utility model proposes an electric control device for an electric heater.

[0038] Please see Figures 1 to 5In one embodiment of this utility model, the electric heater control device 11 is applied to an electric heater, which includes a main housing 31 and a heating element disposed within the main housing 31. The electric heater control device 11 includes:

[0039] The power supply housing 12 has a second accommodating space 121. The second accommodating space 121 contains a power board module 13. The power board module 13 is electrically connected to the heating element. The power supply housing 12 is detachably connected to the main housing 31.

[0040] In this invention, the power board module 13 is concentrated inside the power housing 12, and the power housing 12 and the main housing 31 of the electric heater are detachable. Therefore, when the electric heater malfunctions, the user can remove the original electric heater control device 11 and assemble the new electric heater control device 11 onto the main housing 31 to replace the power board module 13, thus restoring the electric heater to normal use. This operation is relatively simple, simplifying the electric heater repair process. Users can complete the repair of the electric heater at home, which helps improve the convenience of using WeChat.

[0041] In one embodiment, the main housing 31 is provided with a mounting opening 32, into which the power supply housing 12 can be inserted, so that the power supply housing 12 is positioned away from the side panel of the electric heater and close to the mounting opening 32. That is, most of the structure of the power supply housing 12 can extend into the electric heater, reducing the volume of the power supply housing 12 exposed outside the electric heater and protecting the power board module 13 from damage due to impacts between the power supply housing 12 and the outside world. Further, the main housing 31 forms a shaped mounting cavity 34, and the heating element is disposed in the mounting cavity 34. The power supply housing 12 extends into the mounting cavity 34 through the mounting opening 32. At this time, the power supply housing 12 can insulate a portion of the heat emitted by the heating element, protecting the power board module 13. In other embodiments, the main housing 31 may also be provided with a mounting groove, with the mounting opening 32 communicating with the mounting groove, and the power supply housing 12 is housed in the mounting groove.

[0042] In one embodiment, the power supply housing 12 has a mounting protrusion 122 near the mounting opening 32, and the mounting protrusion 122 is connected to the outer end face of the mounting opening 32 by screws. This fixes the power supply housing 12 to the main housing 31, and the power supply housing 12 can be detached from the main housing 31 by unscrewing the screws. In other embodiments, the power supply housing 12 and the main housing 31 can also be fixed by snap-fit.

[0043] In one embodiment, a heat dissipation grille 125 is provided on the side panel of the power supply housing 12 away from the electric heater to dissipate the heat generated when the power board module 13 is working. In other embodiments, a cooling fan may also be installed.

[0044] In one embodiment, the power supply housing 12 includes a power box 126 and a power cover 127. The power cover 127 covers the power box 126 to enclose a second accommodating space 121. A heat dissipation grille 125 and a mounting protrusion 122 are both located on one of the power cover 127 and the power box 126. Further, both the heat dissipation grille 125 and the mounting protrusion 122 are located on the power box 126, meaning the power cover 127 is located within the main housing 31. In other embodiments, both the heat dissipation grille 125 and the mounting protrusion 122 may be located on the power cover 127.

[0045] In one embodiment, the power cover 127 and the power box 126 are connected by screws. This allows the manufacturer or some users to disassemble the power box 126 and the power cover 127 to perform maintenance on the power board module 13 within the second accommodating space 121. In other embodiments, the power cover 127 and the power box 126 may be connected by a bayonet 36.

[0046] This utility model also proposes an electric heater control device 21, which includes a control housing 22 and a control component 23. The control housing 22 is formed with a first accommodating space 221. The control housing 22 is detachably connected to the main housing 31. The bottom side plate of the control housing 22 includes a first side plate 228a extending along the front-rear direction of the main housing 31 and a second side plate 228b extending along the height direction of the main housing 31. The first side plate 228a abuts against the top side plate of the main housing 31, and the second side plate 228b abuts against the rear side plate of the main housing 31. The control component 23 is disposed in the first accommodating space 221 and is electrically connected to the heating element. The control housing 22 and the main housing 31 of the electric heater are detachable. Therefore, when the electric heater malfunctions, the user can remove the original electric heater control device 21 and assemble the new electric heater control device 21 onto the main housing 31 to replace the control component 23, thus restoring the electric heater to use. This operation is relatively simple, simplifying the electric heater repair process. Users can perform electric heater repairs at home, which helps improve the convenience of WeChat.

[0047] In one embodiment, the electric heater control device 21 further includes a power supply housing 12 and a power board module 13. The power supply housing 12 is formed with a second accommodating space 121. The power supply housing 12 is detachably connected to the main housing 31 and is detachably connected to the control housing 22. The power board module 13 is disposed in the second accommodating space 121. The control component 23 is electrically connected to the heating element through the power board module 13. That is, the electric heater control device 21 has an installed state and a disassembled state. In the installed state, both the power supply housing 12 and the control housing 22 are installed on the main housing 31, and the power supply housing 12 and the control housing 22 are connected to each other so that the control housing 22 is also fixed to the main housing 31. In the disassembled state, at least one of the power supply housing 12 and the control housing 22 is removed from the main housing 31. That is, when one of the control components 23 or the power board module 13 fails, only the electric heater control device 21 that fails can be replaced. This facilitates the maintenance of the electric heater and reduces the maintenance cost for users.

[0048] In one embodiment, when the power supply housing 12 is connected to the control housing 22, the first accommodating space 221 and the second accommodating space 121 are connected. This allows the control component 23 and the power board module 13 to be connected via wires. Further, the control component 23 and the power board module 13 have a connector for electrical connection, which, in the installed state, can be accommodated within the first accommodating space 221 or the second accommodating space 121. In other embodiments, the power supply housing 12 and the control housing 22 may also have corresponding conductive metal parts, and the control component 23 and the power board module 13 achieve electrical connection through the mutual abutment of the conductive metal parts.

[0049] In one embodiment, the power supply housing 12 is disposed on the rear side plate of the main housing 31. The power supply housing 12 has a mounting protrusion 122, and mounting ears 222 are respectively provided on opposite sides of the second side plate 228b. The mounting protrusion 122 and the mounting ears 222 are correspondingly arranged, and screws can pass through the mounting ears 222, the mounting protrusion 122, and the main housing 31 in sequence. Further, the mounting protrusion 122 extends along the height direction of the main housing 31, so that the lower end of the mounting protrusion 122 is positioned close to the bottom side of the power supply housing 12, and screws can pass through the lower end of the mounting protrusion 122 and the main housing 31. Furthermore, the mounting protrusion 122 is provided with a first mounting hole 123 near the top side of the power supply housing 12 and a second mounting hole 124 near the bottom side of the power supply housing 12. The mounting ear 222 is provided with a third mounting hole 223 corresponding to the first mounting hole 123. The end face of the mounting opening 32 is provided with a plurality of fourth mounting holes 33, corresponding to the first mounting hole 123 and the second mounting hole 124 respectively. Furthermore, a snap-fit ​​structure 35 is provided between the bottom side plate of the control housing 22 and the top side plate of the main housing 31 to connect the main housing 31 and the control housing 22. In the installation state, after the power housing 12 is inserted into the mounting port 32 and the control housing 22 and the main housing 31 are engaged by the snap-fit ​​structure 35, screws pass through the third mounting hole 223, the first mounting hole 123, and the fourth mounting hole 33 in sequence to connect the control housing 22, the power housing 12, and the main housing 31. Another screw passes through the second mounting hole 124 and the corresponding fourth mounting hole 33 to connect the power housing 12 and the main housing 31. In the disassembly state, when only the control component 23 is replaced, the screws passing through the first mounting hole 123, the third mounting hole 223, and the fourth mounting hole 33 are unscrewed. Then, the control housing 22 is pushed upwards to disengage the snap-fit ​​structure 35 between the control housing 22 and the main housing 31. Finally, the electrical connection between the control component 23 and the power board module 13 is disconnected, thus completing the installation of the control component 23 on the electric heater. To replace only the power board module 13, all screws passing through the first mounting hole 123 and the second mounting hole 124 must be unscrewed to allow the main housing 31 and the power housing 12, and the power housing 12 and the control housing 22 to be detached from each other. The electrical connection between the power board module 13 and the heating element must also be disconnected to replace the power board module 13. When both the power board module 13 and the control assembly 23 need to be replaced, all screws passing through the first mounting hole 123 and the second mounting hole 124 must be unscrewed. The control housing 22 must be pushed upwards to disengage the locking structure 35 between the control housing 22 and the main housing 31, allowing the main housing 31 to be detached from the power housing 12 and the control housing 22. Finally, the electrical connection between the power board module 13 and the heating element must be disconnected to replace the electric heater's control device 21.In other embodiments, the bottom side plate of the control housing 22 and the top side plate of the main housing 31 may be connected by screws, or the end face of the mounting port 32 and the mounting protrusion 122, and the mounting protrusion 122 and the mounting ear 222 may be connected by snap-fit.

[0050] In one embodiment, the snap-fit ​​structure 35 includes a hook 227 disposed on the control housing 22 and a latch 36 disposed on the main housing 31. The hook 227 and the latch 36 snap together along the height direction, and multiple hooks 227 and latches 36 are provided, each corresponding to the other, and arranged at intervals along the left-right direction. In other embodiments, the snap-fit ​​structure 35 may also include a latch 36 disposed on the control housing 22 and a hook 227 disposed on the main housing 31.

[0051] In one embodiment, mounting protrusions 122 are sequentially arranged around the left side plate, bottom side plate, and right side plate of the power supply housing 12. Specifically, there are two first mounting holes 123, located on the left and right sides of the power supply housing 12 respectively; two second mounting holes 124, located on the left and right sides of the power supply housing 12 respectively; and four fourth mounting holes 33, corresponding to the four corners of the mounting opening 32. This ensures a more secure installation.

[0052] In one embodiment, the control housing 22 includes an upper housing 224 and a lower housing 225 to form a first accommodating space 221. A mounting ear 222 is disposed on one of the upper housing 224 and the lower housing 225.

The control panel 232 is located on the top side plate of the upper housing 224 for user operation, and the electronic control board 231 is located in the first accommodating space 221. Furthermore, a latch 227 is disposed on the lower housing 225, and screws securing the upper housing 224 and the lower housing 225 are locked from bottom to top. That is, in the installed state, the screw nuts are blocked by the power supply box 126 and the main housing 31. The upper housing 224 and the lower housing 225 can only be detached after the control housing 22 is separated from the power supply housing 12 and the main housing 31. Furthermore, the bottom side plate of the control housing 22 has a first wire-passing hole 226, and the top side plate of the power supply housing 12 has a second wire-passing hole 128. One of the connectors of the power board module 13 and the control component 23 can pass through the first wire-passing hole 226 and the second wire-passing hole 128 in sequence and connect to the other. In other embodiments, the control housing 22 may also include a front housing and a rear housing assembled in a front-rear direction.

[0053] In one embodiment, the bottom side plate of the control housing 22 further includes a third side plate 228c extending along the front-rear direction of the main housing 31, the third side plate 228c abutting against the top side plate of the power supply housing 12. That is, the first side plate 228a, the second side plate 228b, and the third side plate 228c are all located on the lower shell 225. The rear side plate of the control housing 22 is flush with the top of the rear side plate of the power supply housing 12, which improves the appearance, increases the impact resistance of the power supply housing 12 and the control housing 22, and prevents dust or moisture from entering the first wire passage hole 226 and the second wire passage hole 128.
