[0037] Hereinafter, an electric control box 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0038] like Figure 1-Figure 7 As shown, the electric control box 100 according to an embodiment of the present invention includes: a box assembly 1, a high-current board 2 and a low-current board 3. The box assembly 1 includes a box body 11 and a box cover 12. A first chamber 113 and a second chamber 114 are formed in the box body 11. The entrance of the first chamber 113 and the entrance of the second chamber 114 are both open toward the box cover 12. The box cover 12 cooperates with the box body 11 to close the entrance of the first chamber 113 and the entrance of the second chamber 114; the high-current board 2 is suitable for being loaded into the first chamber 113 through the entrance of the first chamber 113; the low-current board 3 is suitable for being loaded into the second chamber 114 through the entrance of the second chamber 114.

[0039] In this way, interference between the high-voltage board 2 and the low-voltage board 3 can be avoided, and later maintenance is facilitated, thereby improving the practicality of the electric control box 100.

[0040] First, if Figure 1-Figure 2 As shown, the electric control box 100 includes a box assembly 1, a high-voltage board 2, and a low-voltage board 3. The box assembly 1 includes a box cover 12 and a box body 11. A first chamber 113 and a second chamber 114 are formed in the box body 11. The first chamber 113 and the second chamber 114 are spaced apart from each other. The entrance of the first chamber 113 and the entrance of the second chamber 114 are both open toward the box cover 12. The box cover 12 is matched with the open end of the box body 11. The box cover 12 can cooperate with the box body 11 to close the entrance of the first chamber 113 and the entrance of the second chamber 114, thereby achieving the sealing of the first chamber 113 and the second chamber 114.

[0041] Among them, the strong current board 2 is matched with the first chamber 113, and the strong current board 2 can be loaded into the first chamber 113 through the entrance of the first chamber 113; the weak current board 3 is matched with the second chamber 114, and the weak current board 3 can be loaded into the second chamber 114 through the entrance of the second chamber 114, so that the strong current board 2 and the weak current board 3 can be arranged separately.

[0042] During the specific installation process, the box body 11 and the box cover 12 are first separated to open the entrance of the first chamber 113 and the entrance of the second chamber 114; then, the high-current board 2 can be loaded into the first chamber 113 from the entrance of the first chamber 113, and the low-current board 3 can be loaded into the second chamber 114 from the entrance of the second chamber 114; finally, the box cover 12 can be placed on the box body 11 to close the entrance of the first chamber 113 and the entrance of the second chamber 114, thereby enclosing the high-current board 2 and the low-current board 3 in the box assembly 1.

[0043] The above arrangement simplifies the structure of the electric control box 100, making it easy to process and manufacture. It also facilitates the installation of the high-voltage board 2 and the low-voltage board 3 without interfering with each other. Furthermore, by opening the cover 12, the entrances to the first chamber 113 and the second chamber 114 can be simultaneously opened, allowing for wiring, inspection, and panel removal, making subsequent maintenance easier.

[0044] According to the electric control box 100 of the embodiment of the present invention, by installing the high-current board 2 and the low-current board 3 in the first chamber 113 and the second chamber 114 respectively, interference between the high-current board 2 and the low-current board 3 can be avoided, which is beneficial to improving the reliability of the electric control box 100. In addition, by setting the entrance of the first chamber 113 and the entrance of the second chamber 114, they can be opened at the same time when the box cover 12 is opened, which is convenient for later maintenance and improves the practicality of the electric control box 100.

[0045] In some embodiments of the present invention, the box cover 12 is arranged on one side of the box body 11 in the first direction L1, and the strong current board 2 is suitable for being loaded into the first chamber 113 along the first direction L1. The length direction or width direction of the strong current board 2 is parallel to the first direction L1, and the thickness direction of the strong current board 2 is perpendicular to the first direction L1.

[0046] For example, refer to Figure 1-Figure 2 As shown, the box cover 12 is arranged on the box body 11 in the first direction L1 (reference Figure 1 The first chamber 113 extends along the first direction L1 and the entrance is open toward the box cover 12. The strong current board 2 is adapted to move along the first direction L1 to be loaded into the first chamber 113 from the entrance.

[0047] The length direction of the strong current plate 2 can be set parallel to the first direction L1, or the width direction of the strong current plate 2 can be set parallel to the first direction L1, which is not limited by the present invention. At the same time, the thickness direction of the strong current plate 2 can be set perpendicular to the first direction L1.

[0048] Through the above-mentioned arrangement, the space in the insertion direction (i.e., the first direction L1) of the high-voltage board 2 can be fully utilized to reduce the space occupied in the direction perpendicular to the insertion direction. In particular, when the size of the high-voltage board 2 is relatively large, the space occupied in the direction perpendicular to the insertion direction can be effectively reduced, which is conducive to reducing the overall size of the electric control box 100.

[0049] In some embodiments of the present invention, a guide structure 115 is provided in the first chamber 113. The two ends of the first chamber 113 in the first direction L1 are respectively a first end 113a and a second end 113b. The first end 113a forms the entrance of the first chamber 113. The guide structure 115 extends from the first end 113a toward the second end 113b. The guide structure 115 cooperates with the edge of the high-voltage board 2 to guide the movement trajectory of the high-voltage board 2 into the first chamber 113.

[0050] For example, refer to Figure 2-Figure 5 As shown, the two ends of the first chamber 113 in the first direction L1 are respectively set as a first end 113a and a second end 113b, and the first end 113a forms the entrance of the first chamber 113. A guide structure 115 can be provided in the first chamber 113. The guide structure 115 can be configured as a groove and extend from the first end 113a to the second end 113b. The guide structure 115 is used to cooperate with the edge of the strong current board 2. When the strong current board 2 is installed in the first chamber 113, the guide structure 115 can guide the movement trajectory of the strong current board 2 so that the strong current board 2 can be smoothly installed in the first chamber 113.

[0051] Through the above arrangement, the high-voltage board 2 can be inserted quickly, stably and accurately along the set track, avoiding extrusion damage caused by tilting of the high-voltage board 2 during insertion, and reducing the difficulty of assembling the electric control box 100.

[0052] In some embodiments of the present invention, Figure 2 As shown, the length direction of the strong electric board 2 can be set to be parallel to the first direction L1, and the guide structure 115 is set in the width direction of the strong electric board 2 (refer to Figure 2 At least one of the two sides in the left-right direction (shown in the figure). For example, one guide structure 115 can be provided, and the guide structure 115 is located on one side in the width direction of the strong current board 2; or two guide structures 115 can be provided, and the two guide structures 115 are respectively located on both sides in the width direction of the strong current board 2. The present invention does not impose any restrictions on this.

[0053] It is understood that by extending the length of the power board 2 along the first direction L1, the space in the first direction L1 can be more fully utilized, reducing the space occupied perpendicular to the first direction L1, thereby reducing the overall size of the electric control box 100 and facilitating layout. In addition, by arranging the guide structure 115 on one side of the power board 2 along the width direction, the guide structure 115 can more stably guide and cooperate with the power board 2 during the insertion of the power board 2 into the first cavity 113, and the user can more easily observe and control the alignment of the power board 2 and the guide structure 115, thereby improving the installation accuracy of the power board 2.

[0054] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, the guide structure 115 includes a first guide wall 1151 and a second guide wall 1152. The first guide wall 1151 extends from the first end 113a to the second end 113b, and the second guide wall 1152 also extends from the first end 113a to the second end 113b. The first guide wall 1151 and the second guide wall 1152 are spaced apart to form a guide groove 1153 between the first guide wall 1151 and the second guide wall 1152. The guide groove 1153 is matched with the edge of the strong current board 2 so that the edge of the strong current board 2 can pass through the guide groove 1153, thereby allowing the guide groove 1153 to guide the strong current board 2.

[0055] It should be noted that two ribs may be provided on the cavity wall of the first chamber 113 at intervals, with the two ribs facing each other on the first guide wall 1151 and the second guide wall 1152 respectively, and the guide groove 1153 may be defined by the two ribs; or, the guide groove 1153 may be a groove structure recessed in the cavity wall of the first chamber 113, and the present invention does not impose any restrictions on this.

[0056] Through the above-mentioned setting, the guide structure 115 can be simplified, making the guide structure 115 easy to process, reducing the processing cost, and ensuring the guiding effect of the guide structure 115, so that the high-voltage board 2 can be inserted into the first chamber 113 along a stable trajectory, thereby improving the installation accuracy of the high-voltage board 2.

[0057] In some embodiments of the present invention, the guide groove 1153 includes a first groove section 11531, a second groove section 11532 and a third groove section 11533, which are arranged in sequence along the direction from the first end 113a to the second end 113b, and the length of the second groove section 11532 is greater than the lengths of the first groove section 11531 and the third groove section 11533, wherein the width of the first groove section 11531 first decreases and then expands relative to the width of the second groove section 11532 along the direction from the second end 113b to the first end 113a; and / or the width of the third groove section 11533 gradually decreases relative to the width of the second groove section 11532 along the direction from the first end 113a to the second end 113b.

[0058] For example, refer to Figure 5 As shown, the guide groove 1153 includes a first groove section 11531, a second groove section 11532 and a third groove section 11533. The first groove section 11531, the second groove section 11532 and the third groove section 11533 are arranged in sequence along the direction from the first end 113a to the second end 113b, and the length of the second groove section 11532 is greater than the length of the first groove section 11531 and the third groove section 11533.

[0059] Among them, in the direction from the first end 113a to the second end 113b, the width of the first slot section 11531 relative to the second slot section 11532 can be set to first decrease and then expand, so that the first slot section 11531 is formed into a gourd shape. In the process of inserting the high-voltage board 2 into the first chamber 113 from the entrance of the first chamber 113, the first slot section 11531 can first guide the high-voltage board 2 and then position the high-voltage board 2.

[0060] At the same time, in the direction from the first end 113a to the second end 113b, the width of the third slot section 11533 can be set to gradually decrease relative to the width of the second slot section 11532, and the end of the third slot section 11533 away from the second slot section 11532 can be formed as a positioning structure. In the process of inserting the high-voltage board 2 into the first chamber 113 from the entrance of the first chamber 113, the third slot section 11533 can position the end of the high-voltage board 2 to ensure that the high-voltage board 2 is installed in place.

[0061] It can be understood that during the installation of the strong current board 2, the setting of the first groove section 11531 can make the edge of the strong current board 2 easier to insert into the guide groove 1153, reducing the difficulty of installing the strong current board 2, and when the strong current board 2 is installed, the first groove section 11531 and the third groove section 11533 can position the strong current board 2 to reduce the shaking of the strong current board 2, thereby increasing the difficulty of installing the strong current board 2.

[0062] In some embodiments of the present invention, the minimum spacing between the thickness of the strong current board 2 and the first guide wall 1151 and the second guide wall 1152 can be set to be no less than 0.35 mm. This can prevent the strong current board 2 from being squeezed and improve the installation stability of the strong current board 2.

[0063] In some embodiments of the present invention, the box body 11 includes: a first box portion 111 and a second box portion 112, the first box portion 111 is formed into a flat box shape with a box height less than the box length and box width and defines a first chamber 113, the box length direction of the first box portion 111 is parallel to the first direction L1, and the length, width and thickness of the strong current board 2 are consistent with the length, width and height of the first box portion 111; the second box portion 112 is formed into a flat box shape with a box height less than the box length and box width and defines a second chamber 114, and the box height direction of the second box portion 112 is parallel to the first direction L 1, the length, width and thickness of the weak current board 3 are consistent with the length, width and height of the second box part 112; wherein, the second box part 112 is provided on one side of the first box part 111 in the box width direction, and the second box part 112 is aligned with one end of the first box part 111 in the box length direction, and the box cover 12 is provided on the aligned side of the first box part 111 and the second box part 112, so that an air avoidance space 13 is formed on the side of the first box part 111 in the box width direction close to the second box part 112 and on the side of the second box part 112 in the box height direction away from the box cover 12.

[0064] For example, refer to Figure 1-Figure 2 As shown, the box body 11 includes a first box portion 111 and a second box portion 112 connected to each other. The first box portion 111 is formed into a flat box shape with a box height smaller than the box length and box width, and a first chamber 113 is defined in the first box portion 111. The box length direction of the first box portion 111 is parallel to the first direction L1, and the length, width and thickness of the strong current board 2 are consistent with the length, width and height of the first box portion 111. For example, the thickness direction of the strong current board 2 and the box height direction of the first box portion 111 are Figure 1 The left and right directions shown are the length direction of the strong current board 2 and the length direction of the first box part 111. Figure 1 The front-to-back direction, the width direction of the strong current board 2 and the box width direction of the first box part 111 are Figure 1 Up and down directions shown.

[0065] The second box portion 112 is formed into a flat box shape with a box height smaller than the box length and box width, and a second chamber 114 is defined in the second box portion 112. The box height direction of the second box portion 112 is parallel to the first direction L1, and the length, width and thickness of the weak current board 3 are consistent with the length, width and height of the second box portion 112. For example, the thickness direction of the weak current board 3 and the box height direction of the second box portion 112 are Figure 1 The front-to-back direction, the length direction of the weak current board 3 and the box length direction of the second box part 112 are Figure 1 The vertical direction, the width direction of the weak current board 3 and the box width direction of the second box part 112 are Figure 1 Left and right directions shown.

[0066] Among them, the second box part 112 can be arranged on one side of the first box part 111 in the box width direction, and the second box part 112 is aligned with one end of the first box part 111 in the box length direction, the entrance of the first chamber 113 and the entrance of the second chamber 114 are arranged on the aligned side of the first box part 111 and the second box part 112, and the box cover 12 is correspondingly arranged on the aligned side of the first box part 111 and the second box part 112 to close the entrance of the first chamber 113 and the entrance of the second chamber 114.

[0067] At the same time, an air avoidance space 13 can be formed on the side of the first box part 111 close to the second box part 112 in the box width direction, and on the side of the second box part 112 away from the box cover 12 in the box height direction. The air avoidance space 13 is used to avoid the remaining components of the air conditioner 1000, such as the cross-flow fan 200 or the fresh air module 300 described below, so as to achieve compact installation of the electrical control box 100.

[0068] For example, the second box portion 112 can be arranged on the lower side of the first box portion 111, and the second box portion 112 can be aligned with the front end of the first box portion 111. The box cover 12 is arranged on the front side of the first box portion 111 and the second box portion 112, and an air avoidance space 13 is defined on the lower side of the first box portion 111 and the rear side of the second box portion 112.

[0069] It can be understood that by aligning the first box part 111 and the second box part 112, the box cover 12 can be made planar without processing the box cover 12 into a step shape, thereby reducing the difficulty of processing the box cover 12. By setting the air avoidance space 13, the electrical control box 100 can avoid other components, such as the motor of the cross-flow fan 200 or the air inlet chamber of the fresh air module 300, thereby improving space utilization and realizing a compact design of the air conditioner 1000.

[0070] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, one side surface of the weak current board 3 in the thickness direction has a plug-in terminal 31 , and the side surface of the weak current board 3 where the plug-in terminal 31 is provided faces the box cover 12 .

[0071] Specifically, during assembly of the electric control box 100, an operator can access the plug-in terminals 31 through the entrance of the second chamber 114 and close the box cover 12 after the operation is completed, thereby conveniently assembling the electric control box 100. Furthermore, during maintenance of the electric control box 100, an operator can open the box cover 12 to directly expose the plug-in terminals 31, thereby reducing maintenance difficulty. Thus, the convenience of the electric control box 100 can be improved.

[0072] In some embodiments of the present invention, Figure 6 As shown, a snap structure 1141 can be provided in the second chamber 114, and the weak current board 3 is snap-fitted with the snap structure 1141. With the above arrangement, the assembly and disassembly of the weak current board 3 is more convenient, which is beneficial for subsequent maintenance and improves the design rationality of the electric control box 100.

[0073] In some embodiments of the present utility model, a limiting structure 1142 is provided in the second chamber 114, and the limiting structure 1142 is limitedly matched with the weak-current board 3. The limiting structure 1142 and the snap-fit ​​structure 1141 are spaced apart along the width direction of the weak-current board 3. The weak-current board 3 can be snap-fitted with the snap-fit ​​structure 1141 after rotating with the position where the weak-current board 3 and the limiting structure 1142 are limited as the axis.

[0074] Specifically, if Figure 7 As shown, a limiting structure 1142 can be provided in the second chamber 114, and the limiting structure 1142 is provided along the width direction of the weak current board 3 (refer to Figure 7The left and right directions shown in FIG) on one side, the limiting structure 1142 is two, and the two limiting structures 1142 are along the length direction of the weak current board 3 (reference Figure 7 The limiting structure 1142 is provided with a limiting groove, and the end of the weak-current board 3 can be inserted into the limiting groove to be limited and matched with the limiting structure 1142. The snap-fit ​​structure 1141 is provided on the other side of the weak-current board 3 along the width direction, and there are two snap-fit ​​structures 1141. The two snap-fit ​​structures 1141 are arranged spaced apart along the length direction of the weak-current board 3. When the weak-current board 3 is limited and matched with the limiting structure 1142, the position where the weak-current board 3 is limited and matched with the limiting structure 1142 is used as the rotation axis. The weak-current board 3 can be rotated so that the weak-current board 3 can be snap-fitted with the snap-fit ​​structure 1141, thereby installing the weak-current board 3 in the second chamber 114.

[0075] The above configuration can reduce the installation difficulty of the weak current board 3 , reduce the assembly difficulty and maintenance difficulty of the electric control box 100 , and improve the installation stability of the weak current board 3 and the reliability of the electric control box 100 .

[0076] In some embodiments of the present invention, a weak current board installation space is formed in the second chamber 114. The weak current board installation space can be defined by the inner wall of the second chamber 114 and the snap structure 1141 (and / or the limiting structure 1142). The weak current board installation space is used to install the weak current board 3. There can be a matching gap between the thickness of the weak current board 3 and the corresponding sides of the weak current board installation space, and the matching gap is not less than 0.5 mm. In this way, the weak current board 3 can be prevented from being squeezed, thereby improving the installation stability of the weak current board 3.

[0077] The present utility model also provides an air conditioner 1000 .

[0079] According to the air conditioner 1000 of the embodiment of the present invention, by installing the high-current board 2 and the low-current board 3 in the first chamber 113 and the second chamber 114 respectively, interference between the high-current board 2 and the low-current board 3 can be avoided, which is beneficial to improving the reliability of the electric control box 100, and by setting the entrance of the first chamber 113 and the entrance of the second chamber 114, they can be opened at the same time when the box cover 12 is opened, which is convenient for later maintenance, improves the practicality of the electric control box 100, and is beneficial to improving the overall performance of the air conditioner 1000.

[0080] In some embodiments of the present invention, Figure 7-Figure 8As shown, the air conditioner 1000 is a wall-mounted air conditioner, and the air conditioner 1000 also includes a cross-flow fan 200 and a fresh air module 300. The fresh air module 300 is arranged at one axial end of the cross-flow fan 200, and the box body 11 is clamped between the cross-flow fan 200 and the fresh air module 300, and the box body 11 defines an air-avoidance space 13. Part of the cross-flow fan 200 and / or part of the fresh air module 300 occupies the air-avoidance space 13.

[0081] For example, the cross-flow fan 200 may be partially occupied in the avoidance space 13; or, the fresh air module 300 may be partially occupied in the avoidance space 13; or, both the cross-flow fan 200 and the fresh air module 300 may be partially occupied in the avoidance space 13, and the present invention does not impose any restrictions on this.

[0082] Through the above arrangement, the space inside the air conditioner 1000 can be fully utilized, which is beneficial to reducing the overall size of the air conditioner 1000 and realizing a miniaturized design of the air conditioner 1000.
