[0058] like Figures 1 to 6 As shown, Figure 1-8 A in the middle represents the depth direction of the electric control installation cavity 310131013101, B represents the first direction, and C represents the height direction of the box body 10. Figure 4 The arrow in the middle indicates the flow direction of the heat dissipation air path. The first aspect of the present invention proposes an outdoor unit 1, comprising a box body 10, a partition 16, an electric control bracket 31 and an electric control main board 32. The box body 10 is provided with an air outlet and an air return port; the partition 16 separates the interior of the box body 10 into a first cavity 1011 and a second cavity 1012, and the air outlet and the air return port are both connected to the first cavity 1011. The partition 16 is provided with a plurality of air holes 163, and the air holes 163 pass through the partition 16; the electric control bracket 31 includes a bracket body 310, a bracket body 311, and a second cavity 1012. 10 is installed on the partition 16, at least part of the bracket body 310 is located in the second cavity 1012, and an air cavity 164 is formed between the bracket body 310 located in the second cavity 1012 and the partition 16, and the second cavity 1012 is connected to the air hole 163 through the air cavity 164; the electronic control motherboard 32 is installed on the side of the bracket body 310 away from the partition 16 and is located in the second cavity 1012; wherein, at least one air hole 163 is connected to the bottom end of the air cavity 164 and is used to discharge the accumulated liquid in the air cavity 164.

[0059] As can be seen, the outdoor unit 1 proposed by the present invention defines an air cavity 164 between the back side of the electronic control bracket 31 and the partition 16. The air cavity 164 is connected to the first cavity 1011 where the fan is located through the air holes 163 on the partition 16. This allows the fan to extract the hot air in the air cavity 164 and discharge it outside the outdoor unit 1, thereby improving the heat dissipation capacity of the electronic control mainboard 32 and thereby improving the reliability of the electronic control mainboard 32. In addition, the present invention also connects the bottom of the air cavity 164 to the air holes 163, allowing accumulated water in the air cavity 164 to be discharged through the air holes 163, thereby preventing excessive water accumulation, or even water flowing into the second cavity 1012 and affecting other electrical equipment, thereby improving the waterproof performance of the outdoor unit 1.

[0060] In some embodiments of the present invention, the outdoor unit 1 also includes a fan assembly 40 arranged in the first cavity 1011, and the second cavity 1012 is connected to the outside of the outdoor unit 1. The fan assembly 40 is used to form a heat dissipation air path from the outside of the outdoor unit 1 through the second cavity 1012, the air cavity 164, the air hole 163, the first cavity 1011 and the air outlet in sequence.

[0061] It can be seen that the operation of the fan can suck the external air into the second cavity 1012 from the air inlet hole on the box body 10, flow along the air cavity 164 through the electronic control main board 32, and then be sucked into the first cavity 1011 from the air hole 163, and discharged from the air outlet, so that the heat emitted by the electronic control main board 32 can be drawn away and discharged outside the outdoor unit 1, thereby improving the heat dissipation performance of the electronic control main board 32.

[0062] For example, the fan assembly 40 is a standard fan assembly 40 for the side-outlet outdoor unit 1. An air inlet can be provided in the portion of the housing 10 where the second cavity 1012 is provided. The air inlet connects the outside world to the second cavity 1012. For example, the air inlet can be provided near the bottom of the housing 10, and cooperates with the electric control bracket 31 provided on the top of the partition 16 so that the incoming air can flow from bottom to top, thereby flowing through the electric control mainboard 32 to cool the electric control mainboard 32. The electric control mainboard 32 can be mounted on the partition 16 by means of a snap connection or bolt fixation. The electric control mainboard 32 is generally arranged parallel to the partition 16. To facilitate installation and maintenance, the electric control mainboard 32 can be installed near the top of the partition 16. An air inlet 3102 can be set on the top side of the electronic control motherboard 32. The air inlet 3102 is connected to the air cavity 164 on the back side to form a heat dissipation air path. The flowing air can first dissipate heat from the front side of the electronic control motherboard 32 where the electrical components are set, and then enter the air cavity 164 through the air inlet 3102 to dissipate heat from the back side of the electronic control motherboard 32, thereby improving the heat dissipation effect.

[0063] In some embodiments of the present invention, along the height direction of the box body 10, the top end of the bracket body 310 is suspended on the top end of the partition 16, and the top end of the bracket body 310 is provided with an air inlet 3102. The air inlet 3102 is located on the heat dissipation air path and is located between the second cavity 1012 and the air passage cavity 164 in the flow path of the heat dissipation air path.

[0064] As can be seen, by suspending the bracket body 310 on the top of the partition 16, the electronic control bracket 31 is easily installed. Furthermore, an air inlet 3102 is provided to connect the second cavity 1012 and the air passage 164, so that air flowing through the front of the electronic control mainboard 32 enters the air passage 164 through the air inlet 3102 to continue cooling the back of the electronic control mainboard 32 and the electronic control bracket 31.

[0065] For example, the bracket body 310 can be roughly L-shaped, with a hook-shaped structure at its top end for suspension connection with the partition 16. The suspension connection is then secured with bolts to improve the reliability of the connection. The electronic control motherboard 32 is mounted on the front of the bracket body 310. An air inlet 3102 is provided between the suspension connection portion of the electronic control motherboard 32 and the bracket body 310. The number of air inlets 3102 can be one or more, such as a large rectangular opening or multiple circular holes. The air inlet 3102 extends through the electronic control bracket 31 in a direction perpendicular to the electronic control motherboard 32, connecting the air passage 164 on the back side of the electronic control bracket 31 with the second cavity 1012 on the front side of the electronic control bracket 31.

[0066] In some embodiments of the present invention, the bracket body 310 includes a bottom plate 3192 and a surrounding plate 3191. The bottom plate 3192 is arranged opposite to the partition 16. The surrounding plate 3191 is connected to the edge of the bottom plate 3192 and is located between the bottom plate 3192 and the partition 16. An air cavity 164 is defined between the surrounding plate 3191, the bottom plate 3192 and the partition 16. Along the height direction of the box body 10, the bottom end of the surrounding plate 3191 on one side facing the air cavity 164 is connected to at least one air hole 163.

[0067] As can be seen, the enclosing plate 3191 forms a generally U-shaped air passage 164, which, in conjunction with the heat dissipation air path, allows heat from the electronic control bracket 31 and the electronic control mainboard 32 to accumulate within the air passage 164. Air enters through the opening above the air passage 164, and the heat dissipation air flows through the air passage 164, drawing the hot air out of the air passage 164 and discharging it to the outside, thereby improving the heat dissipation effect of the electronic control mainboard 32. The air passage 164 can also receive liquid entering through the air passage holes 163, which can be discharged through the air passage holes 163 at the bottom of the air passage 164.

[0068] Exemplarily, the base plate 3192 can be a rectangular flat plate or other flat plate that matches the shape of the main board. The enclosure 3191 is arranged around the base plate 3192, and an opening is left at the top to facilitate the entry of heat dissipation air. The enclosure 3191 can be extended according to the outer contour of the base plate 3192. The enclosure 3191 can be integrally provided with the base plate 3192 to improve the structural strength. After the electric control bracket 31 is installed on the partition 16, the enclosure 3191 abuts against the partition 16, so that the air cavity 164 is better sealed except for the opening at the top, so as to reduce the water leakage of the air cavity 164. The enclosure 3191 located at the bottom of the base plate 3192 is connected to the air hole 163, that is, the enclosure 3191 located at the bottom is between the upper and lower ends of the air hole 163, so that the accumulated water on the bottom enclosure 3191 can be discharged from the air hole 163. In addition, the bottom enclosure 3191 can also be tilted toward the air hole 163 to reduce the water accumulation phenomenon.

[0069] In some embodiments of the present invention, the bottom plate 3192 is located between the two ends of the enclosure 3191 in a direction perpendicular to the partition 16, and an electric control installation cavity 3101 is defined between the bottom plate 3192 and the end of the enclosure 3191 facing away from the partition 16, and the electric control main board 32 is embedded and installed in the electric control installation cavity 3101.

[0070] It can be seen that by setting the electronic control installation cavity 3101 on the front of the base plate 3192, the electronic control main board 32 can be embedded and installed in the electronic control installation cavity 3101, the enclosure 3191 can protect the electronic control main board 32, and the contact area between the electronic control main board 32 and the electronic control bracket 31 is larger, and the connection is more reliable.

[0071] For example, the enclosure 3191 may be provided in a ring-shaped manner around the bottom plate 3192 on a side of the bottom plate 3192 facing away from the air passage 164, so that the enclosure 3191 can be embedded in and protect the electronic control mainboard 32. The electronic control installation cavity 3101 may be in the shape of a rectangular parallelepiped or other structure that is compatible with the electronic control mainboard 32. A plug-in, clip-on, or retaining structure may also be provided in the electronic control installation cavity 3101 to further secure the electronic control mainboard 32.

[0072] In some embodiments of the present invention, the electric control bracket 31 includes a bracket body 310, a limiting protrusion 317 and a limiting buckle 318. An electric control installation cavity 3101 with one side open is formed inside the bracket body 310. The electric control installation cavity 3101 is used to install the electric control main board 32 of the outdoor unit 1; the limiting protrusion 317 is connected to the bracket body 310 and is arranged in the electric control installation cavity 3101. The limiting protrusion 317 is used to limit the movement of the electric control main board 32 along the depth direction of the electric control installation cavity 3101; the limiting protrusion 317 is used to limit the movement of the electric control main board 32 along the depth direction of the electric control installation cavity 3101; The positioning buckle 318 is connected to the bracket body 310, and at least a portion of the limiting buckle 318 is arranged in the electronic control installation cavity 3101. Along the first direction perpendicular to the depth direction, the limiting buckle 318 is arranged opposite to the limiting protrusion 317. The limiting buckle 318 can move along the first direction to switch between the first position and the second position. The limiting buckle 318 is used to limit the movement of the electronic control main board 32 along the depth direction of the electronic control installation cavity 3101 in the first position. The limiting buckle 318 is separated from the electronic control main board 32 in the second position.

[0073] It can be seen that the electric control bracket 31 proposed in the present invention fixes the electric control main board 32 of the outdoor unit 1 by means of a snap-on installation method. During installation, one side edge of the electric control main board 32 can be fixed to the limiting protrusion 317, and then the other side edge of the electric control main board 32 can be installed into the electric control installation cavity 3101 and fixed by the limiting buckle 318, so that the installation of the electric control main board 32 does not require the use of screws, and the installation is more convenient and more efficient.

[0074] Specifically, if Figures 3 to 6 As shown, in some embodiments of the present invention, the limiting protrusion is spaced apart from the bottom wall of the electric control installation cavity along the depth direction of the electric control installation cavity, the limiting buckle is spaced apart from the bottom wall in the depth direction at the first position, and a first space for fixing the electric control mainboard is formed between the limiting buckle and the bottom wall, and the limiting buckle is staggered with the bottom wall in the first direction at the second position.

[0075] For example, the electrical control bracket 31 is used to mount the electrical control mainboard 32 of the outdoor unit 1 of the HVAC equipment. The mainboard 32 is typically a rectangular plate structure, so the electrical control installation cavity 3101 defined by the bracket body 310 also roughly matches the shape of the mainboard 32. The electrical control bracket 31 can be integrally molded by injection molding or stamped and bent from sheet metal. It can also be a plastic or metal mesh frame structure with multiple hollow areas. One side of the electrical control installation cavity 3101 defined by the electrical control bracket 31 is open for placing the mainboard 32. The electrical control bracket 31 can be mounted on the partition 16 within the outdoor unit 1, or on the housing 10 of the outdoor unit 1, such as on the inside of a panel or a side panel. The installation angle of the electric control bracket 31 can be vertical installation or horizontal installation. Taking vertical installation as an example, the electric control main board 32 is also placed vertically. In order to prevent the electric control main board 32 from tipping over or falling out of the electric control installation cavity 3101, a limiting structure needs to be set inside the electric control installation cavity 3101. Specifically, fixed limiting protrusions 317 and limiting buckles 318 for user operation are respectively provided on both sides of the electric control installation cavity 3101 along the first direction. The limiting buckle 318 can move along the first direction to fix the electric control main board 32 between the bottom wall and the limiting buckle 318 in the first position, and be pulled to the second position so that the electric control main board 32 can be taken out from the electric control installation cavity 3101. During installation, one side of the electronic control main board 32 is inserted between the limiting protrusion 317 and the bottom wall of the electronic control installation cavity 3101, and then the other side is placed into the electronic control installation cavity 3101, and the limiting buckle 318 is moved to the first position to fix the electronic control main board 32 in the electronic control installation cavity 3101.

[0076] It is understood that the depth direction of the electrical control installation cavity 3101 refers to the direction perpendicular to the opening of the open side of the electrical control installation cavity 3101. The limiting protrusion 317 can be a structure that is integrally provided with the bracket body 310 or connected by clamping and welding, and protrudes from the cavity wall of the electrical control installation cavity 3101. The limiting buckle 318 can be integrally provided with the bracket body 310 or connected by clamping and welding. The limiting buckle 318 can be a spring structure, one end of which is connected to the bracket body 310 and the other end of which can swing along a first direction. In the absence of external force, the limiting buckle 318 is located in a first position and is arranged opposite to the bottom wall. It moves to a second position under human power. The limiting buckle 318 can also be a sliding buckle structure with a track, the sliding direction of which is parallel to the first direction. It slides to the first position and is arranged opposite to the bottom wall. It is manually pushed to the second position and is offset from the bottom wall. The sliding buckle structure can also be provided with limiting structures in the first and second positions to prevent the sliding buckle from loosening or deviating. Obviously, by respectively providing a protrusion structure and a limit buckle 318 structure movable along the first direction on opposite sides of the electronic control installation cavity 3101 along the first direction, the electronic control mainboard 32 can be fixed in the electronic control installation cavity 3101 .

[0077] like Figures 3 to 6As shown, in some embodiments of the present invention, the limit buckle 318 includes a spring portion 3181. Along the depth direction, one end of the spring portion 3181 can swing between a first position and a second position. The other end of the spring portion is connected to the bracket body 310. The spring portion 3181 is provided with a snap-fit protrusion 3182 on the side facing the electric control installation cavity 3101. In the first position, the snap-fit protrusion 3182 is spaced apart from the bottom plate 3192 in the depth direction. In the second position, the snap-fit protrusion 3182 is staggered with the bottom plate 3192 in the first direction.

[0078] It can be seen that due to the movable characteristics of the spring piece part 3181, the spring piece part 3181 can swing along the first direction, restricting the electronic control main board 32 between the bottom wall of the electronic control installation cavity 3101 and the clamping protrusion 3182 in the first position, and after being pulled, the clamping protrusion 3182 is driven to be staggered with the bottom plate 3192 in the first direction, so that the installation of the electronic control main board 32 only requires inserting one side of the electronic control main board 32 and fixing the other side with the limit buckle 318, which makes installation more convenient, reduces the use of bolts, and reduces the number of parts.

[0079] Exemplarily, the spring portion 3181 can be a rectangular, elastic sheet-shaped structure, such as a plastic or metal sheet, with a snap-on protrusion 3182 provided on one side of the spring portion 3181. The snap-on protrusion 3182 can be a protrusion formed by integral injection molding or stamping on one side of the spring portion 3181. The snap-on protrusion 3182 can move to a first position during the swinging of the spring portion 3181, facing the bottom wall of the electronic control installation cavity 3101 in the depth direction of the electronic control installation cavity 3101, thereby retaining the electronic control mainboard 32 therebetween. Alternatively, the spring portion 3181 can be connected to a side wall of the electronic control installation cavity 3101 for securement.

[0080] It can be understood that the spring piece portion 3181 is roughly rectangular, and the length direction of the spring piece portion 3181 can be parallel to or perpendicular to the depth direction of the electric control installation cavity 3101, that is, the spring piece portion 3181 can be placed vertically or horizontally relative to the electric control installation cavity 3101, and the angle between the length direction of the spring piece portion 3181 and the depth direction of the electric control installation cavity 3101 is not limited. It is only necessary for the spring piece portion 3181 to be in a natural state so that the snap-fit protrusion 3182 is in the first position and can be spaced from the electric control main board 32 when it is pulled.

[0081] like Figures 1 to 6 As shown, in some embodiments of the present invention, the bracket body 310 includes a surrounding plate 3191 and a bottom plate 3192, the bottom plate 3192 is connected to the surrounding plate 3191, and closes an opening surrounded by the surrounding plate 3191, an electric control installation cavity 3101 is defined between the surrounding plate 3191 and the bottom plate 3192, and the bottom plate 3192 forms a bottom wall on the side facing the electric control installation cavity 3101.

[0082] It can be seen that by setting the bracket body 310 to a rectangular box-shaped structure, the enclosure 3191 extends along the edge of the base plate 3192, and together with the base plate 3192, defines an electric control installation cavity 3101 open on one side. The electric control installation cavity 3101 can be embedded in the electric control main board 32 for installation, and support and protect the electric control main board 32. In conjunction with the spring part 3181 and the limiting protrusion 317, the electric control main board 32 can be snap-fitted and installed in the electric control installation cavity 3101, reducing the use of bolts and facilitating installation.

[0083] For example, the cross-section of the enclosure 3191 along the first direction can be an orifice-shaped to match the outer shape of the electronic control mainboard 32. The enclosure 3191 can be formed by integral injection molding, or formed by multiple plate parts fixed by clamping, bolting, or welding. The bottom plate 3192 is adapted to the opening enclosed by the enclosure 3191. The bottom plate 3192 can be integrally formed with the enclosure 3191, or connected by welding and clamping. When the bottom plate 3192 and the enclosure 3191 are arranged separately, the bottom plate 3192 can be embedded in the opening enclosed by the enclosure 3191 or cover the opening.

[0084] It is understood that the opening enclosed by the enclosure 3191 refers to the openings on opposite sides of the space enclosed by the annular enclosure 3191. One side of the bottom plate 3192 is located within the electrical control installation cavity 3101, and the outer surface of this side serves as the bottom wall of the electrical control installation cavity 3101.

[0085] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, along the depth direction, a receiving notch 3193 is provided on the side of the enclosure 3191 away from the bottom plate 3192, the spring piece portion 3181 is located in the receiving notch 3193, and the spring piece portion 3181 and the enclosure 3191 are an integrated structure.

[0086] It can be seen that by setting an accommodating notch 3193 on the side of the enclosure 3191 away from the bottom plate 3192, the spring portion 3181 can be set in the accommodating notch 3193, which is beneficial to the overall coordinated design of the spring portion 3181 and the enclosure 3191, and can reasonably set the length of the spring portion 3181 in the depth direction of the electric control installation cavity 3101, so that the snap-fitting protrusion 3182 on the spring portion 3181 is flush with the limiting protrusion 317, and then the distance from the snap-fitting protrusion 3182 to the bottom wall is roughly the same as the distance from the limiting protrusion 317 to the bottom wall, which is beneficial to the stability of the electric control main board 32 after embedding and installation.

[0087] Exemplarily, the shape of the accommodating notch 3193 is adapted to the spring plate portion 3181 and is slightly larger than the spring plate portion 3181. The accommodating notch 3193 can be rectangular, arc-shaped, or trapezoidal. The spring plate portion 3181 is integrally formed with the enclosure 3191, so that the bottom end of the spring plate portion 3181 is connected to the enclosure 3191 and the top end can swing between a first position and a second position. Alternatively, the spring plate portion 3181 is provided separately from the enclosure 3191 and mounted on the enclosure 3191, with one end of the spring plate portion 3181 connected to the enclosure 3191. The projection of most of the spring plate portion 3181 in the first direction overlaps with the projection of the accommodating notch 3193, so that when the spring plate portion 3181 swings, the accommodating notch 3193 avoids the spring plate portion 3181 and enables the spring plate portion 3181 to be positioned deeper within the electrical control installation cavity 3101 without exceeding the top end of the enclosure 3191.

[0088] like Figures 3 to 6 As shown, in some embodiments of the present invention, along the depth direction, the side of the locking protrusion 3182 facing away from the bottom plate 3192 has a guide slope 3183, and the guide slope 3183 is set at an angle to the depth direction, and along the depth direction, the distance between the guide slope 3183 and the limiting protrusion 317 in the first direction gradually decreases.

[0089] It can be seen that by providing a guiding slope 3183 on the snap-fit protrusion 3182 to facilitate the electronic control main board 32 to be placed into the electronic control installation cavity 3101 along the depth direction of the electronic control installation cavity 3101, the resistance of the electronic control main board 32 during installation is reduced. By the user pressing down into the electronic control installation cavity 3101, one side of the electronic control main board 32 can be snapped in between the snap-fit protrusion 3182 and the bottom plate 3192, thereby facilitating the installation of the electronic control main board 32.

[0090] For example, the guide slope 3183 can be an arcuate surface or a flat surface, and along the depth direction of the electronic control installation cavity 3101, the end of the guide slope 3183 facing away from the bottom plate 3192 is closer to the spring portion 3181 than the end of the guide slope 3183 facing toward the bottom plate 3192. In short, along the installation direction of the electronic control main board 32, the distance between the guide slope 3183 and the limiting protrusion 317 along the first direction gradually decreases, that is, the opening of the electronic control installation cavity 3101 gradually decreases, thereby facilitating the installation of the electronic control main board 32 into the electronic control installation cavity 3101 along the guide slope 3183 and being fixed between the locking protrusion 3182 and the bottom plate 3192.

[0091] like Figure 5 and Figure 6As shown, in some embodiments of the present invention, the bracket body 310 also includes a plurality of supporting ribs 3199, and the plurality of supporting ribs 3199 are dispersedly arranged on the side of the base plate 3192 facing the electronic control installation cavity 3101. Along the first direction, one side of the electronic control main board 32 is installed between the limiting protrusion 317 and part of the supporting rib 3199, and the other side of the electronic control main board 32 is installed between the clamping protrusion 3182 and another part of the supporting rib 3199.

[0092] As can be seen, by providing multiple supporting ribs 3199 on the bottom wall of the electronic control installation cavity 3101, a gap is created between the electronic control mainboard 32 and the bottom plate 3192, thereby providing heat dissipation space on the back of the electronic control mainboard 32, thereby improving the heat dissipation effect of the electronic control mainboard 32. The supporting ribs 3199 can also connect the bottom plate 3192 and the surrounding plate 3191, thereby strengthening the structural strength of the bracket body 310.

[0093] For example, the support ribs 3199 can be integrally formed with the base plate 3192 and the enclosure 3191. The multiple support ribs 3199 can be arranged in a lattice-like pattern. For example, some support ribs 3199 extend in a first direction, while others extend in a direction angled with the first direction. This creates an interwoven lattice structure of the multiple support ribs 3199, thereby providing more uniform support for the electronic control main board 32 by the support ribs 3199. The ends of some support ribs 3199 can be connected to opposite sides of the enclosure 3191 along the first direction, while the ends of another support rib 3199 can be connected to opposite sides of the enclosure 3191 along the height direction of the outdoor unit 1, thereby enhancing the structural strength of the bracket body 310.

[0094] In addition, support protrusions 31991 can be set at the relative positions of the support rib 3199 and the limiting protrusion 317 along the depth direction of the outdoor unit 1, and at the relative positions of the support rib 3199 and the snap-on protrusion 3182 along the depth direction of the outdoor unit 1 to support the electronic control main board 32, so that along the first direction, one side of the electronic control main board 32 is installed between the limiting protrusion 317 and one of the support protrusions 31991, and the other side of the electronic control main board 32 is installed between the snap-on protrusion 3182 and another support protrusion 31991, and the middle part of the electronic control main board 32 does not contact the support rib 3199, forming a space for ventilation and heat dissipation, thereby improving the ventilation and heat dissipation effect of the electronic control main board 32.

[0095] like Figures 2 to 6As shown, in some embodiments of the present invention, the electric control bracket 31 further includes at least one wire clamp structure 316, which is arranged on the side of the enclosure 3191 away from the electric control installation cavity 3101. A wire clamping space 3161 is defined between the wire clamp structure 316 and the enclosure 3191. The wire clamp structure 316 can move along a first direction and has a third position for clamping the wiring harness of the electric control main board 32, and a fourth position for loosening the wiring harness.

[0096] It can be seen that by arranging at least one wire clamp structure 316 on the electronic control bracket 31, the wire harness connected to the electronic control main board 32 can be clamped by the wire clamp structure 316, so that the wire harness is not easy to smell during transportation or use, thereby making the wire harness more stable and not easy to fall off at the connection point, or collide with other sharp structures, causing the wire harness to wear and fail, thereby improving the reliability of the wire harness.

[0097] For example, the wire clamp structure 316 can be a sheet-shaped structure with elasticity, and its shape is not limited. One end of the wire clamp structure 316 is connected to the enclosure 3191, and the other end can be manually opened to clamp part of the wire harness between the wire clamp structure 316 and the enclosure 3191. The wire clamp structure 316 can be integrally formed with the enclosure 3191 or connected by snap bolts. The elasticity of the wire clamp structure 316 can be achieved by its own material, or by adopting a structure similar to a clip and achieved by a spring. Obviously, the wire clamp structure 316 only needs to ensure that it has the elasticity to drive it to move toward the enclosure 3191.

[0098] like Figures 2 to 6 As shown, in some embodiments of the present invention, the wire clamp structure 316 includes a connecting section 3162, a clamping section 3163 and a lever means 3164 connected in sequence, the connecting section 3162 is connected to the enclosure 3191 at one end away from the clamping section 3163, at least a portion of the clamping section 3163 is spaced apart from the enclosure 3191, and a clamping space is defined between the clamping section 3163 and the enclosure 3191, and the lever means 3164 is used for being pressed by a hand to move the clamping section 3163 along a first direction toward a direction away from the enclosure 3191.

[0099] It can be seen that by setting the wire clamp structure 316 to a three-section type, the wire clamp structure 316 is fixed on the enclosure 3191, and a clamping space is formed between the wire clamp structure 316 and the enclosure 3191. The wire clamp structure 316 also has a lever means 3164 that is easy to operate, so that the user can press down the lever means 3164 to drive the clamping section 3163 away from the enclosure 3191, place the wiring harness in the clamping space, and then release the lever means 3164, so that the wire clamp structure 316 moves toward the enclosure 3191 under its own elasticity to clamp the wiring harness, thereby improving the stability of the wiring harness and reducing accidental wear of the wiring harness and the phenomenon of the end falling off.

[0100] Exemplarily, the wire clamp structure 316 can be a plastic sheet structure or a metal sheet structure, and the whole is roughly arc-shaped. The connecting section 3162 is the part that connects the wire clamp structure 316 and the enclosure 3191, and can be integrally formed with the enclosure 3191. The clamping section 3163 is arc-shaped, one end is connected to the connecting section 3162, and the other end is provided with a lever means 3164. The recessed area of the clamping section 3163 is set toward the enclosure 3191, and the end where the clamping section 3163 is connected to the lever means 3164 is spaced apart from the enclosure 3191 to form a clamping space, or is closely arranged to form a clamping space when the wrench is turned. The lever means 3164 extends in the direction away from the enclosure 3191 and is arranged at an angle to the enclosure 3191. The outer surface of one side of the lever means 3164 is V-shaped with the enclosure 3191, which is convenient for the user to press the lever means 3164 to drive the clamping section 3163 away from the enclosure 3191.

[0101] like Figures 2 to 6 As shown, in some embodiments of the present invention, along the depth direction, at least one wire notch 3194 is provided on the side of the enclosure 3191 facing away from the bottom plate 3192, and at least one wire clamp structure 316 is provided on the circumferential outer side of each wire notch 3194.

[0102] It can be seen that a wire passing notch 3194 or multiple wire passing notches 3194 can be set on the enclosure 3191, and multiple wire passing notches 3194 are arranged on the enclosure 3191 at intervals along the circumference of the electric control installation cavity 3101, so that the wiring harness connected to the electric control main board 32 can pass through the enclosure 3191 from the wire passing notch 3194, and thus be connected to other electrical equipment. A wire clamp structure 316 is set on the circumferential side of the wire passing notch 3194 to fix the wiring harness, reduce the direct contact between the wiring harness and the enclosure 3191, thereby reducing the friction between the wiring harness and the enclosure 3191 and improving the durability of the wiring harness.

[0103] For example, the wire-passing notch 3194 can be rectangular, arc-shaped, or trapezoidal. The corners of the wire-passing notch 3194 can be rounded to reduce wear on the wiring harness. The wire-passing notch 3194 can be integrally molded by injection molding on the side of the enclosure 3191 facing away from the base plate 3192, or it can be formed by shearing on the side of the enclosure 3191 facing away from the base plate 3192. The wire clamp structure 316 can be positioned on either side of or below the wire-passing notch 3194 as needed, depending on the subsequent routing of the wiring harness.

[0104] like Figures 2 to 6 As shown, in some embodiments of the present invention, the electric control bracket 31 also includes a protective plate 3195. Along the depth direction, one side of the protective plate 3195 is connected to the enclosure 3191, and the other side of the protective plate 3195 extends in a direction away from the enclosure 3191 and exceeds the side of the enclosure 3191 away from the bottom plate 3192.

[0105] It can be seen that by setting a protective plate 3195 that extends beyond the enclosure 3191 in the depth direction of the electrical control installation cavity 3101, the surrounding side of the electrical control installation cavity 3101 has a partially higher plate structure, thereby protecting some electronic components with weak structures on the electrical control main board 32 and reducing the impact of external forces on these electronic components.

[0106] For example, the protective plate 3195 can be integrally formed with the enclosure 3191 by injection molding, so that the protective plate 3195 is an extension structure of the enclosure 3191 away from the end of the electric control installation cavity 3101. According to actual needs, multiple protective plates 3195 can be arranged at intervals on the enclosure 3191. The position of the protective plate 3195 is set according to the position of the weak electronic components such as capacitors on the electric control main board 32. For example, if the capacitor is arranged at the corner of the rectangular electric control main board 32, the protective plate 3195 can be set to L-shaped and located at the corner of the enclosure 3191 to improve the protection effect of the capacitor, and the L-shaped structure has good structural strength. The protective plate 3195 can also be set separately from the enclosure 3191, for example, the protective plate 3195 is installed at at least one position of the enclosure 3191 by welding, bonding, clamping or bolting, which is more flexible in arrangement and can also reduce costs.

[0107] like Figure 6 As shown, in some embodiments of the present invention, the electric control bracket 31 also includes a connecting column 3196 arranged in the electric control installation cavity 3101, one end of the connecting column 3196 is connected to the bottom wall, the axis of the connecting column 3196 is parallel to the depth direction, and the connecting column 3196 is used to be plugged into the assembly hole of the electric control main board 32.

[0108] It can be seen that by setting the connecting column 3196 in the electronic control installation cavity 3101, the assembly hole on the electronic control main board 32 can be matched with the connecting column 3196 to further fix the electronic control main board 32 and improve the reliability of the connection between the electronic control main board 32 and the electronic control bracket 31.

[0109] Exemplarily, the connecting post 3196 can be cylindrical or prismatic, with its axis parallel to the depth of the electronic control mounting cavity 3101. One axial end of the connecting post 3196 is connected to the bottom wall of the electronic control mounting cavity 3101. The connecting post 3196 can be integrally molded with the electronic control bracket 31 through injection molding to ensure a reliable connection. Along the depth of the electronic control mounting cavity 3101, the axial length of the connecting post 3196 is greater than the distance from the bottom wall of the electronic control mounting cavity 3101 to the stop protrusion 317. This ensures that, after the electronic control mainboard 32 is installed, the connecting post 3196 is long enough to be inserted into the assembly hole on the electronic control mainboard 32.

[0110] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, the electric control bracket 31 can be suspended and mounted on the partition 16 within the outdoor unit 1, so that the electric control bracket 31, the partition 16, and the heat exchanger 61 are all placed vertically along the height direction of the outdoor unit 1, saving space within the outdoor unit 1 and facilitating the arrangement of other components. Specifically, the top side of the electric control bracket 31 can be provided with a downwardly opening groove that cooperates with the top side of the partition 16 to achieve suspended mounting. In addition, to facilitate the arrangement of the wiring harness, a wiring hole 3197 or a wiring groove can be set on the top side of the electric control bracket 31 to connect the first cavity 1011 and the second cavity 1012 separated by the partition 16. The compressor 51 and the electric control bracket 31 are both located in the second cavity 1012. The wiring harness of the electric control main board 32 installed on the electric control bracket 31 can be connected to the fan assembly 40 and sensors and other devices located in the first cavity 1011. The wiring hole 3197 and the wiring groove can be located along the first direction, on the side of the panel of the outdoor unit 1 at the top of the electric control bracket 31, so that the wiring harness and electric control can be directly observed and contacted after the panel is disassembled, so as to facilitate the inspection of the electric control part.

[0111] In some embodiments of the present invention, the partition 16 has multiple shielding pieces 1631, which cover the air holes 163. The shielding pieces 1631 are constructed to block the liquid from the first cavity 1011 from entering the air holes 163 and to guide the air flow passing through the air holes 163.

[0112] It can be seen that by arranging a shielding piece 1631 on the air hole 163, the shielding piece 1631 can block the liquid from the first cavity 1011 from entering the air hole 163, and guide the airflow of the air hole 163 to flow in a preset direction, thereby improving the waterproof performance of the air hole 163 and improving the heat dissipation effect of the electronic control motherboard 32.

[0113] Exemplarily, the shielding piece 1631 can be located in the upper half of the air hole 163 and set at an angle to the height direction of the box body 10. The upper side of the shielding piece 1631 is connected to the partition 16, and the lower side is suspended and inclined in the direction away from the partition 16, so that the liquid from above the air hole 163, such as rainwater leaking from the top of the box body 10, can be blocked by the shielding piece 1631 to prevent it from entering the air hole 163, and the inclined design of the shielding piece 1631 allows the liquid falling on the shielding piece 1631 to slide down, reducing water accumulation.

[0114] In some embodiments of the present invention, the electric control bracket 31 is an integrated structure. The electric control bracket 31 is manufactured through an integrated molding process, so that the overall structural strength of the electric control bracket 31 is higher.

[0115] It is understandable that if Figure 1As shown, the second aspect of the present invention provides a HVAC device, including the outdoor unit 1 provided in the first aspect of the present invention.

[0116] It can be seen that the outdoor unit 1 of the HVAC equipment proposed in the third aspect of the present invention has an electric control bracket 31 for convenient installation of the electric control main board 32. The outdoor unit 1 can be the outdoor unit 1 of the air conditioner, or the outdoor unit 1 of other HVAC equipment. The electric control bracket 31 can fix the electric control main board 32 of the outdoor unit 1 by means of a snap-in installation. During installation, one side of the electric control main board 32 can be snap-in between the limiting protrusion 317 and the bottom wall of the electric control installation cavity 3101, and then the other side of the electric control main board 32 can be installed in the electric control installation cavity 3101 and fixed by the limiting buckle 318, so that the installation of the electric control main board 32 does not require the use of screws, and the installation is more convenient and more efficient.

[0117] It is understandable that the HVAC equipment may be an air conditioner or other cooling and heating equipment.

[0118] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
