[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0038] With the popularization of variable-frequency refrigerators, it is now necessary to equip variable-frequency refrigerators with reactors to enhance the performance of the electronic control system. For a variable-frequency control board with a built-in reactor, its structural stability is relatively good, and the connection between the circuit board and the reactor is relatively stable. For a variable-frequency control board that has been produced without a reactor, an external reactor needs to be connected to the variable-frequency control board. However, the structural stability of the split-type reactor and the variable-frequency control board is poor, and the connection is prone to instability, thereby affecting the performance of the refrigerator electronic control system.

[0039] An embodiment of the present application provides an electronic control box assembly. Exemplarily, please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the electronic control box assembly provided by the embodiment of the present application. The electronic control box assembly 100 includes a box body 110, a variable-frequency control board 120, and a reactor 130.

[0040] Among them, the variable-frequency control board 120 is installed in the box body 110; the reactor 130 is arranged in the box body 110 and is electrically connected to the variable-frequency control board 120. One of the box body 110 and the reactor 130 is provided with a plug-in part, and the other is provided with a plug-in slot. The plug-in part is inserted into the plug-in slot so that the reactor is fixed on the box body.

[0041] It should be noted that the reactor 130 and the variable-frequency control board 120 may be connected by wiring.

[0042] The electronic control box assembly 100 provided by the embodiment of the present application supports and fixes the external reactor 130 by adding a slot or a plug-in part suitable for plugging with the reactor 130 on the box body 110, ensuring a stable connection between the reactor 130 and the variable-frequency control board 120.

[0043] In a preferred embodiment, the variable-frequency control board 120 includes a circuit board 121 and electrical components 122 connected to each other. Along the thickness direction of the circuit board 121, the reactor 130 is disposed opposite to the circuit board 121, and the reactor 130 and the electrical components 122 are located on the same side of the circuit board 121.

[0044] It should be noted that there are multiple electrical components 122 on the circuit board 121, and the types of the multiple electrical components 122 are not single. When the reactor 130 is arranged close to the circuit load and the circuit switch, better usage effects can be achieved; therefore, by arranging the reactor 130 and the electrical components 122 on the same side of the circuit board 121, the usage effect of the reactor can be improved. In addition, the multiple electrical components 122 usually do not cover the entire circuit board 121, and even if they do, there are still situations where the multiple electrical components 122 are at different heights; if the reactor 130 and some of the electrical components 122 can be arranged side by side in the extending direction of the circuit board 121, the space occupied by the combination of the reactor 130 and the variable-frequency control board 120 in the thickness direction of the circuit board 121 can also be compressed. However, the specific relative setting position between the reactor 130 and the circuit board 121 can be selected by the designer considering the actual arrangement of the multiple electrical components 122 and the usage effect of the reactor 130.

[0045] Exemplarily, please refer to Figure 2 , Figure 2 is Figure 1 the exploded view of the electric control box assembly shown. The box body 110 includes a bottom plate 111 and a circumferential side plate 112. The bottom plate 111 and the circumferential side plate 112 enclose to form an installation groove 113, and the installation groove 113 is suitable for the variable-frequency control board 120 and the reactor 130 to be installed; the circuit board 121 is arranged opposite to the bottom plate 111, and a plug-in groove 114 is formed on the circumferential side plate 112. The reactor 130 includes a reactor body 132 and a plug-in portion 131, and the plug-in portion 131 is plugged into the plug-in groove 114 so that the reactor body 132 is fixed on the circumferential side plate 112.

[0046] It should be noted that the circuit board 121 is arranged opposite to the bottom plate 111. The electrical components 122 can be arranged on the surface of the circuit board 121 facing the bottom plate 111, or on the surface of the circuit board 121 facing away from the bottom plate 111. Optionally, as Figure 1 , the electrical components 122 are arranged on the surface of the circuit board 121 facing away from the bottom plate 111. The reactor 130 is inserted into the plug-in groove 114 through the plug-in portion 131, so as to be hung on the circumferential side plate 112 and located between the circuit board 121 and the notch of the installation groove 113.

[0047] Optionally, the circumferential side plate 112 includes a plug-in wall 1121 facing away from the bottom plate 111, and the plug-in groove 114 is formed on the plug-in wall 1121. It can be understood that the plug-in wall 1121 is located outside the installation groove 113. When installing the electric control box assembly 100, the installer directly inserts the plug-in portion 131 of the reactor 130 into the plug-in groove 114 from outside the box body 110, without first placing it into the installation groove 113 and then inserting it into the plug-in groove 114. Since the space of the installation groove 113 is limited, the installer's operating space is restricted. If it is directly inserted from the outside, the installer's operating space will not be restricted, reducing the installation difficulty and improving the installation efficiency.

[0048] In some embodiments, please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the plug-in groove provided by the embodiment of the present application. The electric control box assembly 100 further includes a cover body 140, and the cover body 140 is adapted to cover the plug-in wall 1121 to cover the notch of the installation groove 113. An avoidance opening 1141 communicating with the installation groove 113 is formed on the side wall of the plug-in groove 114, and the avoidance opening 1141 communicates with the notch of the plug-in groove 114. The plug-in portion 131 is connected to the reactor body 132 through the avoidance opening 1141. Along the plug-in direction of the plug-in portion 131, the position of the plug-in portion 131 is lower than the plug-in wall 1121 or the top surface of the plug-in portion 131 away from the bottom plate 111 is flush with the plug-in wall 1121.

[0049] It should be noted that the cover body 140 is used to cover the notch of the installation groove 113 to play roles such as dust prevention and heat insulation. To avoid interference between the plug-in portion 131 protruding partially from the plug-in wall 1121 and the cover body 140, resulting in the cover body 140 not being able to be covered tightly, the avoidance opening 1141 is formed so that the plug-in portion 131 is connected to the reactor body 132 from the side of the plug-in groove 114, and the plug-in portion 131 is not higher than the plug-in wall 1121. In this way, the problem of interference between the plug-in portion 131 and the cover body 140 can be avoided.

[0050] The cover body 140 is rotatably connected to the box body 110, for example, so that the cover body 140 rotates to open or cover the notch of the installation groove 113. One of the cover body 140 and the box body 110 is provided with a hook, and the other is provided with a slot, and the hook is engaged in the slot to fix the cover body 140 to the box body 110. Exemplarily, as Figure 2 , a hook is provided at one end of the cover body 140 away from the rotating shaft, and a slot is provided at the corresponding position on the box body 110.

[0051] Exemplarily, refer to Figure 4 - Figure 5 , Figure 4 which is a schematic structural diagram of the reactor provided by the embodiment of the present application, Figure 5The structural schematic diagram of the reactor provided by the embodiment of the present application is installed on the circumferential side plate. The insertion part 131 includes a first insertion piece 1311 and a second insertion piece 1312. The first insertion piece 1311 and the second insertion piece 1312 are respectively connected to opposite ends of the reactor body 132, and the extending directions are opposite. Along the first direction H1, the first insertion piece 1311, the avoidance opening 1141, and the second insertion piece 1312 are arranged in sequence, and the first direction H1 is perpendicular to the insertion direction of the insertion part 131.

[0052] It can be understood that by fixing the two ends of the reactor body 132 through the first insertion piece 1311 and the second insertion piece 1312 respectively, the stability of the reactor 130 installed on the box body 110 can be improved, and the structural strength can be enhanced.

[0053] In some embodiments, a rib 115 protrudes from the inner wall of the insertion slot 114, and the first insertion piece 1311 and the second insertion piece 1312 are clamped between the rib 115 and the side wall of the insertion slot 114. Optionally, as Figure 3 , there are multiple ribs 115. The insertion slot 114 includes a first side wall 1142 and a second side wall 1143 that are spaced apart from and opposite to the first insertion piece 1311 and the second insertion piece 1312. The multiple ribs 115 protrude from the first side wall 1142 to clamp the first insertion piece 1311 and the second insertion piece 1312 between the rib 115 and the second side wall 1143. For the convenience of inserting the first insertion piece 1311 and the second insertion piece 1312, a guiding inclined surface extending along the insertion direction of the insertion part 131 can be provided on the rib 115.

[0054] To improve the structural strength of the box body 110, a reinforcing rib 116 can also protrude from the first side wall 1142. The reinforcing rib 116 abuts against the reactor body 132 to support the reactor body 132 and strengthen the structural strength of the first side wall 1142.

[0055] In some embodiments, please refer to Figure 6 , Figure 6It is a schematic structural diagram of the box body provided by the embodiment of the present application. An installation buckle 117 is arranged in the installation groove 113, and the circuit board 121 is clamped between the installation buckle 117 and the bottom plate 111. Exemplarily, at least one installation buckle 117 is respectively protruded from the opposite two side edges of the bottom plate 111, and the installation buckles 117 on both sides are symmetrically arranged. The installation buckle 117 and the bottom plate 111 enclose a clamping through groove, and the edge of the circuit board 121 is clamped in the clamping through groove for limiting. It can be understood that the installation buckles 117 on both sides of the bottom plate 111 respectively fix both sides of the circuit board 121 to realize the stable installation of the circuit board 121. Optionally, two installation buckles 117 are respectively protruded from both sides of the bottom plate 111, and the two installation buckles 117 on the same side are arranged at intervals. Among them, a heat dissipation port 118 can also be opened on the side wall of the box body 110, so that the frequency conversion control board 120 in the box body 110 can be timely dissipated of heat to avoid overheating and damage of the frequency conversion control board 120.

[0056] The electric control box assembly 100 provided by the embodiment of the present application is provided with a slot or a plug-in part suitable for being plugged into the reactor 130 on the box body 110, so as to support and fix the external reactor 130 and ensure the stable connection between the reactor 130 and the frequency conversion control board 120.
