[0039] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0040] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0041] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0042] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0043] like Figures 1 to 8 As shown, Figure 1-8 In the diagram, direction A indicates the height of outdoor unit 1, and direction B indicates the direction through which the maintenance port 1001 is located. Figure 3The dashed line indicates the direction of the wiring harness of connector 321 extending to the first cavity 1011. The first aspect of this utility model proposes an outdoor unit 1, including a housing 10, an electrical control bracket 31, and an electrical control main board 32. The housing 10 forms a receiving cavity 101 inside, and the housing 10 is provided with a maintenance port 1001 communicating with the receiving cavity 101. The electrical control bracket 31 is installed in the receiving cavity 101 and defines an electrical control mounting cavity 3101 that is open on one side. The electrical control main board 32 is embedded in the electrical control mounting cavity 3101. The electrical control main board 32 is parallel to or at an angle to the through direction of the maintenance port 1001. Along the through direction of the maintenance port 1001, the opposite sides of the electrical control main board 31 have a first edge and a second edge, respectively. The first edge is located between the maintenance port 1001 and the second edge. The electrical control main board 32 has multiple connectors 321. Along the through direction of the maintenance port 1001, the multiple connectors 321 are arranged closer to the first edge than the second edge.

[0044] As can be seen, the outdoor unit 1 proposed in this utility model fixes the electronic control motherboard 32 by placing the connector 321 on the side of the electronic control motherboard 32 close to the electronic control motherboard 32 and embedding the electronic control motherboard 32 in the electronic control bracket 31. Then, the electronic control bracket 31 is installed in the housing 10, and the side of the electronic control motherboard 32 with the connector 321 is placed close to the maintenance port 1001. This makes it convenient for users to access the wiring of the electronic control motherboard 32 from the maintenance port 1001, thereby facilitating the wiring, installation and maintenance of the electronic control motherboard 32 and improving the user experience.

[0045] For example, the electrical control bracket 31 is used to mount the electrical control main board 32 of the outdoor unit 1 of the HVAC equipment. The electrical control main board 32 is typically a rectangular plate structure. Therefore, the electrical control mounting cavity 3101 defined by the bracket body 310 is also roughly adapted to the shape of the electrical control main board 32. The electrical control bracket 31 can be injection molded as a single piece, or formed by stamping and bending sheet metal parts. It can also be a plastic mesh frame or metal mesh frame structure with multiple hollow areas. One side of the electrical control mounting cavity 3101 defined by the electrical control bracket 31 is open to accommodate the electrical control main board 32. The electrical control bracket 31 can be mounted on the partition 16 inside the outdoor unit 1, or on the housing 10 of the outdoor unit 1, for example, inside the front panel 12 or the side panel. The first edge and the second edge of the electrical control main board 32 refer to the two opposite edges of the approximately rectangular plate body of the electrical control main board 32 along the through direction of the maintenance opening 1001. The main control board 32 is provided with multiple connectors 321. The connectors 321 are used for wire harness insertion to electrically connect the main control board 32 to other equipment of the outdoor unit 1, such as the fan assembly 40 and various sensors. To facilitate the wiring, installation and maintenance of the main control board 32, the connectors 321 can be set closer to the first edge than the second edge, that is, set on one side of the main control board 32 in the direction parallel to its own surface. After the main control board 32 is installed in the receiving cavity 101 by the main control bracket 31, the connectors 321 are set close to the maintenance port 1001. That is, the main control board 32 and the maintenance port 1001 are set at an angle other than 90°, and the connectors 321 are located on the side of the main control board 32 in the direction parallel to its own surface that is close to the maintenance port 1001. The user can directly contact the connectors 321 from the maintenance port 1001, which is convenient for wiring, installation and maintenance.

[0046] like Figures 1 to 3 As shown, in some embodiments of this utility model, the housing 10 includes a top cover 14, a left side plate 131, a chassis 11, and a right side plate 132 connected in sequence. The top cover 14, the left side plate 131, the chassis 11, and the right side plate 132 together form a receiving cavity 101. The outdoor unit also includes a partition 16 disposed in the receiving cavity. The edges of the top cover 14, the partition 16, the chassis 11, and the right side plate 132 on the same side together form a maintenance opening 1001. The housing 10 also includes a front panel 12. The front panel 12 is detachably connected to at least one of the top cover 14, the left side plate 131, the chassis 11, and the right side plate 132, and closes at least part of the maintenance opening 1001.

[0047] As can be seen, the receiving cavity 101 is defined by the top cover 14, the left side plate 131, the chassis 11 and the right side plate 132 connected in sequence. The front panel 12 is detachably connected to at least one of the top cover 14, the left side plate 131, the chassis 11 and the right side plate 132 to close the maintenance port 1001, thereby forming a closed space inside the enclosure 10 to protect the internal equipment.

[0048] For example, the top cover 14, left side panel 131, chassis 11, and right side panel 132 are generally rectangular in shape, with flanges at their edges to facilitate interconnection and improve sealing. The edges of the top cover 14, left side panel 131, chassis 11, and right side panel 132 on the same side enclose a maintenance opening 1001, which can be sealed by the front panel 12 to improve airtightness. The front panel 12 is generally rectangular, and its four edges can be detachably connected to the top cover 14, left side panel 131, chassis 11, and right side panel 132 using bolts, clips, hooks, or other detachable connection methods. An air outlet can also be provided on the front panel 12, and an air outlet grille can be used to cover the outlet to improve sealing. When it is necessary to install or maintain equipment within the maintenance cavity 101, such as the main control board 32, fan assembly 40, compressor 51, etc., the front panel 12 can be removed to expose the maintenance opening 1001, allowing operation of the main control board 32.

[0049] It is understandable that the edge of the same side of the top cover 14, the left side panel 131, the chassis 11 and the right side panel 132 refers to the front side of the outdoor unit 1. An air outlet screen is also provided on the front side to exhaust the air from the fan assembly 40. The heat exchanger 61 is arranged on the rear side of the outdoor unit 1. That is, the maintenance port 1001 and the heat exchanger 61 are located on the front and rear sides of the outdoor unit 1, respectively.

[0050] like Figures 5 to 7 As shown, in some embodiments of this utility model, the electrical control bracket 31 includes a base plate 3192 and a surrounding plate 3191. The surrounding plate 3191 is connected to the base plate 3192 and extends along the circumferential edge of the base plate 3192. An electrical control mounting cavity 3101 is defined between the base plate 3192 and the surrounding plate 3191. At least one wire passage notch 3194 is provided on the surrounding plate 3191. The wire passage notch 3194 communicates with the electrical control mounting cavity 3101. Along the through direction of the maintenance port 1001, the wire passage notch 3194 is provided on the side of the opposite sides of the surrounding plate 3191 that is closer to the maintenance port 1001.

[0051] As can be seen, by setting the bracket body 310 into a rectangular box structure, the surrounding plate 3191 extends along the edge of the base plate 3192 and together with the base plate 3192 defines an open electrical control mounting cavity 3101 on one side. The electrical control mounting cavity 3101 can be embedded and installed in the electrical control motherboard 32, and supports and protects the electrical control motherboard 32. A wire passing notch 3194 is provided on the surrounding plate 3191 to facilitate the wire harness connected to the electrical control motherboard 32 to pass through, and the surrounding plate 3191 also has the function of protecting the electrical control motherboard 32.

[0052] For example, the cross-section of the enclosure 3191 along the first direction can be U-shaped to fit the shape of the electronic control main board 32. The enclosure 3191 can be integrally molded by injection molding, or formed by multiple plates connected by snap-fit, bolts, or welding. The base plate 3192 is adapted to an opening formed by the enclosure 3191. The base plate 3192 can be integrally molded with the enclosure 3191, or welded and snap-fit ​​connected. In the case where the base plate 3192 and the enclosure 3191 are separately arranged, the base plate 3192 can be embedded in or cover the opening formed by the enclosure 3191.

[0053] Specifically, the wire passage notch 3194 can be rectangular, arc-shaped, or trapezoidal. The corners of the wire passage notch 3194 can be rounded to reduce wear on the wire harness. The wire passage notch 3194 can be integrally injection molded onto the side of the enclosure plate 3191 opposite to the bottom plate 3192, or it can be formed by cutting on the side of the enclosure plate 3191 opposite to the bottom plate 3192. The wire clamp structure 316 is set on both sides or below the wire passage notch 3194 as needed, depending on the subsequent routing of the wire harness.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the outdoor unit 1 further includes a compressor 51, a fan assembly 40, and a partition 16. The partition 16 is disposed in the receiving cavity 101 and connected to the housing 10. The partition 16 divides the receiving cavity 101 into a first cavity 1011 and a second cavity 1012. The fan assembly 40 is located in the first cavity 1011, the compressor 51 is located in the second cavity 1012, the electrical control bracket 31 is mounted on the partition 16, and the electrical control main board 32 is located in the second cavity 1012.

[0055] As can be seen, the partition 16 divides the accommodating cavity 101 into two parts: the first cavity 1011 and the second cavity 1012. The heat exchange part of the outdoor unit 1, namely the fan assembly 40 and the heat exchanger 61, is located in the first cavity 1011, while the remaining electrical control, compressor 51 and piping parts are located in the second cavity 1012, making the overall layout more reasonable.

[0056] For example, the partition 16 is generally rectangular and may have a certain degree of bending to reasonably allocate the space within the accommodating cavity 101. The partition 16 can be fixed to the chassis 11, the heat exchanger 61, or the front panel 12. The electrical control bracket 31 can be installed on the partition 16 by bolts, snap-fit, or hook-fitting to achieve the fixation of the electrical control bracket 31.

[0057] It is understandable that the front panel 12 can be divided into two parts according to the two openings formed by the first cavity 1011 and the second cavity 1012. The first part of the front panel 12 is located at the opening of the first cavity 1011, and the second part of the front panel 12 is located in the opening of the second cavity 1012. Since a maintenance port 1001 is required, the opening of the second cavity 1012, that is, the opening formed by the edge of the partition 16, part of the top cover 14, the right side plate 132 and part of the chassis 11 on the same side, can be set as the maintenance port 1001 and closed by the second part of the front panel 12. This way, when inspecting the electronic control main board 32, it is not necessary to remove the entire front panel 12, but only the second part of the front panel 12 needs to be removed, making the operation more convenient.

[0058] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this utility model, along the height direction of the outdoor unit 1, the top of the electrical control bracket 31 is suspended on the partition 16. The top of the electrical control bracket 31 is higher than the top of the partition 16 in the height direction. The top of the electrical control bracket 31 is provided with a wiring channel. The second cavity 1012 is connected to the first cavity 1011 through the wiring channel.

[0059] As can be seen, by suspending the electrical control bracket 31 on the partition 16 inside the outdoor unit 1, the electrical 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 internal space of the outdoor unit 1 and facilitating the arrangement of other components.

[0060] For example, the top of the electrical control bracket 31 can be L-shaped and have a downward-facing groove that mates with the top of the partition 16 to achieve suspended installation. Additionally, to facilitate wiring, a wiring channel can be provided at the top of the electrical control bracket 31. This channel connects the first cavity 1011 and the second cavity 1012 separated by the partition 16. Both the compressor 51 and the electrical control main board 32 are located within the second cavity 1012. The wiring harness of the electrical control main board 32 can be connected to the fan assembly 40 and sensors located within the first cavity 1011 via the wiring channel.

[0061] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this utility model, a wiring space 3198 is formed between the side of the enclosure 3191 with the wire passage notch 3194 and the front panel 12, and the wiring space 3198 is connected to the wiring channel.

[0062] As can be seen, the wiring channel can be positioned between the maintenance port 1011 and the wiring notch 3194 in the through direction of the maintenance port 1001. The side of the enclosure 3191 with the wiring notch 3194 is spaced apart from the inner side of the front panel 12, forming a wiring space 3198. This allows the wire harness of the connector 321 to pass through the wiring notch 3194 and out of the electrical control bracket 31, then extend through the wiring space 3198 to the wiring channel, and finally into the first cavity 1011 to electrically connect with the fan assembly 40 and sensors, etc. The wiring space 3198 is located behind the maintenance port 1001, facilitating wiring installation and maintenance after the front panel 12 is removed.

[0063] In addition, the wiring channel is located at the top of the electrical control bracket 31 and is closer to the maintenance port 1001 along the through direction of the maintenance port 1001, so that the wiring harness passing through the wiring channel can be directly observed and touched after the front panel 12 is removed, which facilitates the maintenance of the electrical control part.

[0064] like Figure 1 and Figure 3-7 As shown, in some embodiments of this utility model, the wiring channel includes a wiring groove 3197. Along the height direction of the outdoor unit 1, the upper surface of the top of the electrical control bracket 31 is partially recessed to form the wiring groove 3197. The two ends of the wiring groove 3197 are respectively connected to the wiring space and the first cavity 1011.

[0065] As can be seen, the wiring channel can be in the form of a wiring groove 3197, so that after one end of the wire harness is connected to the connector 321, the slot of the wire harness sub-wiring groove 3197 is pressed into the wiring groove 3197 to realize the installation of the wire harness. The wire harness is fixed by the wiring groove 3197, improving the reliability of the connection, and realizing the connection of the wire harness from the second cavity 1012 to the first cavity 1011.

[0066] For example, the extension direction of the cable tray 3197 can be straight or arc-shaped, depending on the cable arrangement. The cross-section of the cable tray 3197 along the height of the outdoor unit 1 can be rectangular, trapezoidal, or arc-shaped. Alternatively, the cable channel can also be a cable hole, allowing the wire harness from the electronic control motherboard 32 to pass through the cable hole and electrically connect to the fan assembly 40 and sensors and other devices in the first cavity 1011. The cable hole can better fix the wire harness and protect it, improving the reliability of the wire harness.

[0067] like Figures 3 to 6 As shown, in some embodiments of this utility model, the surface of the electronic control main board 32 is arranged parallel to the height direction of the outdoor unit 1, and multiple connectors 321 are spaced apart along the height direction of the outdoor unit 1.

[0068] And / or, the surface of the electronic control main board 31 is set parallel to the height direction of the outdoor unit 1, and along the height direction of the outdoor unit 1, multiple connectors 321 are set closer to the bottom side of the electronic control main board 32 than the top side of the electronic control main board 32.

[0069] As can be seen, by arranging multiple connectors 321 at intervals along the height direction of the outdoor unit 1, the distance from each connector 321 to the maintenance port 1001 is minimized, thereby facilitating the user's access to the connector 321 from the maintenance port 1001 and making the installation and maintenance of the connector 321 and wiring convenient.

[0070] For example, the connector 321 can be set on the side of the electronic control main board 32 near the maintenance port 1001, and arranged lower in the height direction of the outdoor unit 1, so that the connector 321 is as far away from the top cover 14 as possible and is set closer to the bottom side of the electronic control main board 32. This reduces the encroachment of the top cover 14 on the operating space during the installation and maintenance of the connector 321 and wiring, and improves the convenience of user operation.

[0071] like Figures 3 to 7 As shown, in some embodiments of the present invention, the electrical control bracket 31 is provided with at least one wire clamp structure 316. Along the through direction of the maintenance port 1001, the wire clamp structure 316 is disposed on the side closer to the maintenance port 1001 on opposite sides of the electrical control bracket 31 and is used to clamp the wire harness connected to the connector 321.

[0072] As can be seen, by setting at least one wire clamp structure 316 on the electronic control bracket 31, the wire harness connected to the electronic control motherboard 32 can be clamped by the wire clamp structure 316, making the wire harness less prone to odor during transportation or use, thereby improving the stability of the wire harness, making it less likely to fall off at the connection point or collide with other sharp structures, resulting in wear and failure of the wire harness, and improving the reliability of the wire harness.

[0073] For example, the wire clamp structure 316 can be a flexible sheet-like structure, the shape of which is not limited. One end of the wire clamp structure 316 is connected to the surrounding plate 3191, and the other end can be manually pried open to clamp part of the wire harness in the clamping space 3161 between the wire clamp structure 316 and the surrounding plate 3191. The wire clamp structure 316 can be integrally formed with the surrounding plate 3191 or connected by snap-fit ​​bolts. The elasticity of the wire clamp structure 316 can be achieved by its own material or by adopting a clamp-like structure, achieved by a spring. Obviously, the wire clamp structure 316 only needs to ensure that it has the elasticity to drive itself to move towards the surrounding plate 3191.

[0074] like Figures 3 to 7As shown, in some embodiments of this utility model, the wire clamp structure 316 includes a connecting section 3162, a clamping section 3163, and a lever 3164 connected in sequence. One end of the connecting section 3162 away from the clamping section 3163 is connected to the surrounding plate 3191. At least a portion of the clamping section 3163 is spaced apart from the surrounding plate 3191 and defines a clamping space 3161 between it and the surrounding plate 3191. The lever 3164 is used for pressing by hand to make the clamping section 3163 move in a first direction away from the surrounding plate 3191.

[0075] As can be seen, by setting the wire clamp structure 316 into a three-section configuration, the wire clamp structure 316 is fixed to the enclosure plate 3191, and a clamping space is formed between the wire clamp structure 316 and the enclosure plate 3191. The wire clamp structure 316 also has a convenient lever 3164, which allows the user to press down the lever 3164 to move the clamping section 3163 away from the enclosure plate 3191, place the wire harness in the clamping space, and then release the lever 3164. This allows the wire clamp structure 316 to move towards the enclosure plate 3191 under its own elasticity, thereby clamping the wire harness, improving the stability of the wire harness, and reducing the phenomenon of accidental wear and end detachment of the wire harness.

[0076] For example, the wire clamp structure 316 can be a plastic sheet structure or a metal sheet structure, and the whole is generally arc-shaped. The connecting section 3162 is the part that connects the wire clamp structure 316 to the surrounding plate 3191, and can be integrally formed with the surrounding plate 3191. The clamping section 3163 is arc-shaped, with one end connected to the connecting section 3162 and the other end provided with a lever 3164. The recessed area of ​​the clamping section 3163 is set towards the surrounding plate 3191. The end of the clamping section 3163 connected to the lever 3164 is spaced apart from the surrounding plate 3191 to form a clamping space, or is set close to the surrounding plate 3191 to form a clamping space when the lever is turned. The lever 3164 extends away from the surrounding plate 3191 and is set at an angle to the surrounding plate 3191. One side of the outer surface of the lever 3164 forms a V-shape with the surrounding plate 3191, so that the user can press the lever 3164 to move the clamping section 3163 away from the surrounding plate 3191.

[0077] like Figure 1 As shown, the second aspect of this utility model provides a heating, ventilation and air conditioning (HVAC) device, including the outdoor unit 1 proposed in the first aspect of this utility model.

[0078] The outdoor unit 1 of the HVAC equipment proposed in the second aspect of this utility model has an electrical control main board 32 that facilitates installation, maintenance, and wiring. By placing the connector 321 on the side of the electrical control main board 32 close to the side of the electrical control main board 32, the electrical control main board 32 is embedded in the electrical control bracket 31 to fix the electrical control main board 32. Then, the electrical control bracket 31 is installed in the housing 10, and the side of the electrical control main board 32 with the connector 321 is placed close to the maintenance port 1001, so that the wiring of the electrical control main board 32 can be easily accessed by the user from the maintenance port 1001, thereby facilitating the user's wiring, installation, and maintenance of the electrical control main board 32 and improving the user experience.

[0079] Understandably, the HVAC equipment could be an air conditioner or other heating and cooling system.
