Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to an electrical control box and an integrated heat pump unit. Background Technology

[0002] Existing integrated heat pump units, also known as heat pump air conditioner outdoor units, integrate a water circulation system on the basis of traditional air conditioner outdoor units to achieve heating and hot water supply in winter.

[0003] In the electrical control section, existing integrated heat pump units generally use dual control boards, which means adding an auxiliary control board to the traditional main control board of the air conditioner to control the operation of the water circulation system. Traditionally, the drive board and main control board of the outdoor unit are mounted together using a bracket. If the auxiliary control board is added directly to the bracket, the space occupied by the electrical control section increases; if the auxiliary control board is installed independently, it needs to be electrically connected to the main control board, increasing wiring complexity; if the main control board and auxiliary drive board are mounted together using a control board bracket, with the main control board on the front and the auxiliary drive board on the back, and the high-heat-generating drive board installed independently using a drive board bracket, it becomes difficult to inspect the auxiliary control board on the back during after-sales maintenance. It may require disassembling adjacent components (such as the top cover, sound insulation panel, etc.) to remove the control board bracket, making maintenance of the auxiliary control board on the back quite troublesome. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide an electrical control box for an integrated heat pump machine, which has a reasonable layout and is convenient for after-sales maintenance.

[0005] This utility model is achieved through the following technical solution: an electrical control box for an integrated heat pump machine, comprising a drive board assembly and a control board assembly; the drive board assembly includes a drive board bracket and a drive board disposed on the drive board bracket; the control board assembly includes a control board bracket, a first control board disposed on the front side of the control board bracket, and a second control board disposed on the back side of the control board bracket; the control board bracket and the drive board bracket are detachably connected; the drive board and the second control board are respectively electrically connected to the first control board.

[0006] Compared with existing technologies, the electrical control box provided by this utility model independently mounts the high-heat-generating drive board via a drive board bracket, and mounts the first and second control boards via a control board bracket. The control board bracket and drive board bracket are then detachably connected. On the one hand, the electrical control components of the integrated heat pump unit are rationally laid out, avoiding both space occupation and complex wiring. On the other hand, the detachable connection between the control board bracket and drive board bracket facilitates the disassembly and assembly of the control board bracket, making after-sales maintenance convenient.

[0007] Furthermore, the control board bracket and the drive board bracket are arranged perpendicularly to each other. The drive board bracket includes a main bracket and a first connector and a second connector respectively disposed at the top and bottom of the main bracket. The first connector and the second connector are detachably connected to the control board bracket. The perpendicular arrangement of the control board bracket and the drive board bracket reduces the coverage area of ​​the control board bracket on the drive board bracket, preventing heat generated by the drive board from accumulating between the two brackets and affecting the normal operation of the drive board, the first control board, and the second control board. The first connector and the second connector ensure a certain gap between the control board bracket and the drive board bracket, which aids in heat dissipation.

[0008] Furthermore, the first connector is a Z-shaped connector, which includes a support portion disposed on the top of the main bracket and a connecting portion disposed at the end of the support portion. The connecting portion is detachably connected to the top of the control board bracket. The Z-shaped connector enables a non-planar connection between the drive board bracket and the control board bracket. Simultaneously, the Z-shaped connector avoids stress concentration and provides good structural stability.

[0009] Furthermore, the end of the connecting part is provided with a first positioning groove, and the top of the control board bracket is provided with a first positioning flange. The first positioning flange matches the shape of the first positioning groove and is inserted into the first positioning groove. The connecting part is detachably connected to the first positioning flange. The design of the first positioning groove and the first positioning flange facilitates the positioning and installation between the control board bracket and the drive board bracket.

[0010] Furthermore, the first positioning groove has a first through hole on the side near the front of the control board bracket, and the first positioning flange has a first fastening hole on the side corresponding to the first through hole; it also includes a first fastener, which passes through the first through hole and engages with the first fastening hole. The first through hole, the first fastening hole, and the first fastener enable a detachable connection between the first connector and the control board bracket.

[0011] Furthermore, a first insertion hole is provided on the side of the first positioning folded edge away from the top of the control board bracket, and a first pin is provided on the side of the connecting part corresponding to the first insertion hole. The first pin is inserted into the first insertion hole and abuts against the inner surface of the first positioning folded edge. The first pin and the first insertion hole increase the support for the control board bracket, thereby improving the stability of the connection between the control board bracket and the drive board bracket.

[0012] Furthermore, the second connector has a second positioning groove at its end, and the control board bracket has a second positioning flange at its bottom. The second positioning flange matches the shape of the second positioning groove and is inserted into the second positioning groove. The second connector is detachably connected to the second positioning flange. The design of the second positioning groove and the second positioning flange facilitates the positioning and installation between the control board bracket and the drive board bracket.

[0013] Furthermore, the second positioning groove has a second through hole on the side facing away from the control board bracket, and the second positioning flange has a second fastening hole on the side corresponding to the second through hole; it also includes a second fastener, which passes through the second through hole and engages with the second fastening hole; the second positioning flange has a second insertion hole on the side facing the bottom of the control board bracket, and the second connector has a second pin on the side corresponding to the second insertion hole, which is inserted into the second insertion hole and abuts against the inner surface of the second positioning flange. The second through hole, the second fastening hole, and the second fastener enable a detachable connection between the first connector and the control board bracket. The second pin and the second insertion hole increase support for the control board bracket, thereby improving the stability of the connection between the control board bracket and the drive board bracket.

[0014] Furthermore, the support portion is detachably connected to the main bracket, and the support portion is provided with a limiting groove for the main bracket to be inserted, the limiting groove extending along the length direction of the main bracket. The design of the limiting groove helps to position the first connector on the main bracket during installation, while preventing the first connector from becoming loose in the horizontal direction.

[0015] Furthermore, it also includes a mounting base for mounting the terminal block, the mounting base being disposed at the bottom of the control board bracket, the control board bracket being detachably connected to the second connector via the mounting base. The mounting base for mounting the terminal block facilitates wiring and routing for the first and second control boards.

[0016] This utility model also provides an integrated heat pump unit, including a chassis, a fan, a compressor, a partition, and an electrical control box for the integrated heat pump unit as described above; the partition is disposed inside the chassis and divides the internal space of the chassis into a first installation space and a second installation space disposed on the left and right, the fan is disposed in the first installation space, and the compressor is disposed in the second installation space; the drive board bracket is disposed on the top of the partition along the length direction of the partition, and the front and rear sides of the drive board bracket are detachably connected to the chassis respectively, the control board bracket is disposed in the second installation space, and the side of the control board bracket away from the drive board bracket is detachably connected to the chassis.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Example 1

[0029] like Figures 1 to 7 As shown, the electrical control box of the integrated heat pump unit provided in this embodiment includes a drive board assembly and a control board assembly. The drive board assembly includes a drive board bracket 10 and a drive board 20 disposed on the drive board bracket 10. The control board assembly includes a control board bracket 30, a first control board 40 disposed on the front of the control board bracket 30, and a second control board 50 disposed on the back of the control board bracket 30. The control board bracket 30 is detachably connected to the drive board bracket 10. The drive board 20 and the second control board 50 are electrically connected to the first control board 40, respectively. The drive board 20, which generates significant heat, is independently mounted on the drive board bracket 10, while the first control board 40 and the second control board 50 are mounted on the control board bracket 30. The control board bracket 30 is then detachably connected to the drive board bracket 10. On the one hand, the electrical control components of the integrated heat pump unit are rationally laid out, avoiding both space occupation and complex wiring. On the other hand, the detachable connection between the control board bracket 30 and the drive board bracket 10 facilitates the disassembly and assembly of the control board bracket 30, making after-sales maintenance convenient.

[0030] In this embodiment, the control board bracket 30 and the drive board bracket 10 are arranged perpendicularly to each other. The drive board bracket 10 includes a main bracket 11, and a first connector 12 and a second connector 13 respectively disposed at the top and bottom of the main bracket 11. The first connector 12 and the second connector 13 are detachably connected to the control board bracket 30. The perpendicular arrangement of the control board bracket 30 and the drive board bracket 10 reduces the coverage area of ​​the control board bracket 30 on the drive board bracket 10, preventing heat generated by the drive board 20 from accumulating between the drive board bracket 10 and the control board bracket 30, thus affecting the normal operation of the drive board 20, the first control board 40, and the second control board 50. The first connector 12 and the second connector 13 ensure a certain gap between the control board bracket 30 and the drive board bracket 10, which helps with heat dissipation. Of course, in other alternative embodiments, the control board bracket 30 and the drive board bracket 10 are not limited to being perpendicular; they can be parallel or at a certain angle. The first connector 12 and the second connector 13 are not limited to being respectively disposed at the top and bottom of the main support 11, but can also be disposed at other positions of the main support 11.

[0031] In this embodiment, the main support 11 includes a mounting plate 111 and a fixing bracket 112 for fixing the drive plate 20. The mounting plate 111 has a mounting opening 113 for placing the fixing bracket 112, and the bottom of the mounting plate 111 has a folded edge 114 for limiting and supporting the fixing bracket 112. The front and rear sides of the mounting plate 111 are respectively provided with a first assembly part 119 and a second assembly part 120 for assembly with the chassis of the integrated heat pump unit. One side of the fixing bracket 112 has a boss 115 that matches the mounting opening 113. The boss 115 is engaged with the mounting opening 113 and protrudes from the mounting plate 111 through the mounting opening 113. The side of the fixing bracket 112 facing away from the boss 115 has a first mounting groove 116, the boss 115 has a second mounting groove 117, and the fixing bracket 112 has a heat dissipation vent 118 that connects the first mounting groove 116 and the second mounting groove 117. The second connector 13 is connected to the mounting plate 111, and the first connector 12 is connected to the mounting plate 111 and the fixing frame 112.

[0032] The drive board 20 includes a substrate 21, a heat sink 22, and several electronic components. The substrate 21 is disposed within the first mounting slot 116, and the heat sink 22 is disposed within the second mounting slot 117. Electronic components that generate significant heat are disposed on the side of the substrate 21 facing the heat sink 22 and contact the heat sink 22 through the heat dissipation port 118; the remaining electronic components are disposed on the side of the substrate 21 away from the heat sink 22. The control board bracket 30 is disposed on the side of the drive board bracket 10 away from the heat sink 22, and a third mounting part 37 for assembly with the chassis of the integrated heat pump unit is provided on the side of the control board bracket 30 away from the drive board bracket 10. In this embodiment, the substrate 21, mounting plate 111, and fixing bracket 112 are all rectangular structures. Of course, in other alternative embodiments, they can be circular, elliptical, or other polygonal shapes; irregular shapes can also be designed according to actual conditions, and there are no limitations on this.

[0033] In this embodiment, the first connector 12 is a Z-shaped connector, which includes a support portion 121 disposed on the top of the main bracket 11 and a connecting portion 122 disposed at the end of the support portion 121. The connecting portion 122 is detachably connected to the top of the control board bracket 30. The Z-shaped connector 12 enables a non-planar connection between the drive board bracket 10 and the control board bracket 30. Furthermore, the Z-shaped connector avoids stress concentration and provides good structural stability. Of course, in other alternative embodiments, the first connector 12 is not limited to a Z-shaped structure; it only needs to enable a non-planar connection between the drive board bracket 10 and the control board bracket 30, and this is not a limitation.

[0034] In this embodiment, the end of the connecting portion 122 is provided with a first positioning groove 1221, and the top of the control board bracket 30 is provided with a first positioning folded edge 31. Specifically, the first connecting member 12 is a plate-shaped structure, and the two sides of the connecting portion 122 are folded downward to form the first positioning groove 1221. The control board bracket 30 is also a plate-shaped structure, and the top of the control board bracket is folded in the direction away from the first control board 40 to form the first positioning folded edge 31. The shape of the first positioning folded edge 31 matches the first positioning groove 1221 and is inserted into the first positioning groove 1221, and the connecting portion 122 is detachably connected to the first positioning folded edge 31. The design of the first positioning groove 1221 and the first positioning folded edge 31 facilitates the positioning and installation between the control board bracket 30 and the drive board bracket 10.

[0035] In this embodiment, the first positioning groove 1221 has a first through hole 1223 on the side near the front of the control board bracket 30, and the first positioning flange 31 has a first fastening hole 33 on the side corresponding to the first through hole 1223; it also includes a first fastener 70, which passes through the first through hole 1223 and engages with the first fastening hole 33. The first fastening hole 33 is a threaded hole, and the first fastener 70 is a screw. The first through hole 1223, the first fastening hole 33, and the first fastener 70 enable a detachable connection between the first connector 12 and the control board bracket 30. Furthermore, the first fastener 70 and the first fastening hole 33 are located on the front of the control board, facilitating the disassembly and assembly of the first fastener 70 by maintenance personnel, thus simplifying maintenance. Of course, in other alternative embodiments, the detachable connection between the control board bracket 30 and the first connector 12 is not limited to the first fastening hole 33 and the first fastener 70; a snap-fit ​​or other method can also be used to achieve the detachable connection.

[0036] Furthermore, the first positioning flange 31 has a first insertion hole 32 on the side away from the top of the control board bracket 30, and the connecting part 122 has a first pin 1222 on the side corresponding to the first insertion hole 32. The first pin 1222 is inserted into the first insertion hole 32 and abuts against the inner surface of the first positioning flange 31. The first pin 1222 and the first insertion hole 32 increase the support for the control board bracket 30, thereby improving the stability of the connection between the control board bracket 30 and the drive board bracket 10.

[0037] In this embodiment, the second connector 13 is a plate-like structure with a second positioning groove 131 at its end. The bottom of the control board bracket 30 has a second positioning flange 34. The second positioning flange 34 matches the shape of the second positioning groove 131 and is inserted into the second positioning groove 131. The second connector 13 and the second positioning flange 34 are detachably connected. The design of the second positioning groove 131 and the second positioning flange 34 facilitates the positioning and installation between the control board bracket 30 and the drive board bracket 10. In this embodiment, the second positioning groove 131 is a right-angle positioning groove, and the second positioning flange 34 is a right-angle flange that matches the right-angle positioning groove. Of course, in other alternative embodiments, the second positioning groove 131 can be a recess, and the second positioning flange 34 can be a flange that matches the recess. In this embodiment, the second connector 13 is integrally designed with the mounting plate 111. Of course, in other alternative embodiments, the second connector 13 can be separately designed from the mounting plate 111 and can be connected by screws, clips, or welding.

[0038] In this embodiment, the second positioning groove 131 has a second through hole 133 on the side facing away from the control board bracket 30, and the second positioning flange 34 has a second fastening hole 36 on the side corresponding to the second through hole 133; it also includes a second fastener 80, which passes through the second through hole 133 and engages with the second fastening hole 36. The second through hole 133, the second fastening hole 36, and the second fastener 80 enable a detachable connection between the second connector 13 and the control board bracket 30. Furthermore, the second fastener 80 is located on the side facing away from the control board bracket 30, i.e., on the same side as the first fastener 70, which facilitates easy assembly and disassembly. Of course, in other alternative embodiments, the detachable connection between the control board bracket 30 and the second connector 13 is not limited to the second fastening hole 36 and the second fastener 80; it can also be achieved through snap-fit ​​mechanisms or other means.

[0039] Furthermore, the second positioning flange 34 has a second insertion hole 35 on the side facing the bottom of the control board bracket 30, and the second connector 13 has a second pin 132 on the side corresponding to the second insertion hole 35. The second pin 132 is inserted into the second insertion hole 35 and abuts against the inner surface of the second positioning flange 34. The second pin 132 and the second insertion hole 35 increase the support for the control board bracket, thereby improving the stability of the connection between the control board bracket and the drive board bracket.

[0040] In this embodiment, the support portion 121 is detachably connected to the main bracket 11. The support portion 121 is provided with a limiting groove 1211 for the main bracket 11 to be inserted into, and the limiting groove 1211 extends along the length direction of the main bracket 11. Specifically, the support portion 121 is provided with a first folded edge 1212, a second folded edge 1213, and a third folded edge 1214. The first folded edge 1212 is located at the end of the support portion 121 away from the connecting portion 122. The second folded edge 1213 and the third folded edge 1214 are both parallel to the first folded edge 1212 and are located on both sides of the end of the support portion 121 away from the connecting portion 122. The second folded edge 1213 and the third folded edge 1214 are on the same plane, and the first folded edge 1212, the second folded edge 1213, and the third folded edge 1214 define the limiting groove 1211. After assembly, the mounting plate 111 and the fixing bracket 112 of the main support 11 are inserted into the limiting groove 1211. The second folded edge 1213 and the third folded edge 1214 respectively abut against the side of the fixing bracket 112 away from the mounting plate 111, and the first folded edge 1212 abuts against the side of the mounting plate 111 away from the fixing bracket 112. The design of the limiting groove 1211 helps to position the first connector 12 on the main support 11 and prevents the first connector 12 from loosening in the horizontal direction. Of course, in other alternative embodiments, the first connector 12 can be integrally designed with the main support 11, or it can be fixed to the main support 11 by welding, bonding or other methods.

[0041] In some optional embodiments, the electrical control box further includes a mounting base 60 for mounting a terminal block. The terminal block is used for wiring and routing of the first and second control boards, such as connecting to an external power supply. The mounting base 60 has an L-shaped structure and is disposed at the bottom of the control board bracket 30. The control board bracket 30 engages with the second positioning groove 131 of the second connector 13 via the mounting base 60, and the control board bracket 30 is detachably connected to the second connector 13 via the mounting base 60. The mounting base 60 and the control board bracket 30 are integrated into one piece. Of course, in other optional embodiments, the mounting base 60 and the control board bracket 30 can be separate and connected by welding, snap-fit, or screws.

[0042] It should be noted that the electrical control box described in this embodiment does not have a casing to enclose the drive board 20, control board bracket 30, first control board 40, and second control board 50 for waterproof sealing. Of course, in other alternative embodiments, the electrical control box may include a casing, such as one with an opening on one side, the drive board bracket 10 covering the opening, the heat sink 22 of the drive board 20 exposed through the opening, and the control board bracket 30, first control board 40, and second control board 50 housed within the casing, with wiring holes provided on the casing. The above is an illustrative description; the structure of the casing can be designed according to actual needs and is not limited here.

[0043] During installation, the first connector 12 is installed on the drive board bracket 10 on which the drive board 20 is installed. Then, the first positioning flange 31 and the second positioning flange 34 of the control board bracket 30 on which the first control board 40 and the second control board 50 are installed are aligned and pushed into the first positioning groove 1221 and the second positioning groove 131, respectively. At the same time, the first pin 1222 and the second pin 132 are inserted into the first socket 32 ​​and the second socket 35, respectively. Finally, the drive board bracket 10 and the control board bracket 30 are fixed with the first fastener 70 and the second fastener 80 to complete the installation. During disassembly, only the first fastener 70 and the second fastener 80 need to be removed, and the control board bracket 30 can be pushed out to allow the second control board 50 on the control board bracket 30 to be inspected.

[0044] Compared with existing technologies, the electrical control box provided by this utility model independently mounts the high-heat-generating drive board via a drive board bracket, and mounts the first and second control boards via a control board bracket. The control board bracket and drive board bracket are then detachably connected. On the one hand, the electrical control components of the integrated heat pump unit are rationally laid out, avoiding both space occupation and complex wiring. On the other hand, the detachable connection between the control board bracket and drive board bracket facilitates the disassembly and assembly of the control board bracket, making after-sales maintenance convenient.
