The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] The following describes a HVAC equipment outdoor unit 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0036] As shown in FIG. 1 , FIG. 2 and FIG. 9 , the HVAC outdoor unit 1 according to the present invention includes a housing 100 , a fan, a first mesh cover 300 and a second mesh cover 400 .

[0037] An outer wall of the housing 100 has an air outlet area 110 and an electrical area 120, and the air outlet area 110 is provided with an air outlet 111. In some embodiments, the housing 100 includes a main body 140 and a first side panel 150, the main body 140 has a first direction (the direction indicated by arrow A in the accompanying drawings) and a second direction (the direction indicated by arrow B in the accompanying drawings) perpendicular to each other, an outer wall of the main body 140 in the first direction has an air outlet area 110 and an electrical area 120, and the air outlet area 110 is provided with an air outlet 111. The first side panel 150 is detachably connected to one side of the main body 140 in the second direction. The fan is provided in the housing 100 and is located at the air outlet 111, that is, the fan corresponds to the air outlet 111. The first mesh cover 300 is provided on the main body 140 and blocks at least a portion of the air outlet area 110. The second mesh cover 400 is detachably mounted on the main body 140 and shields at least a portion of the electrical area 120 . The first mesh cover 300 and the second mesh cover 400 are arranged along the second direction. The first side plate 150 is located on the side of the second mesh cover 400 facing away from the first mesh cover 300 in the second direction.

[0038] When the first side plate 150 is connected to the main body 140, it abuts against the second mesh cover 400 to limit the second mesh cover 400 to a fixed position; when the first side plate 150 is separated from the main body 140, the second mesh cover 400 is movable between the fixed position and the plug-in position.

[0039] For example, the HVAC equipment may include at least one of an air conditioner, a multi-split unit, a heat pump, a water heater, and a swimming pool unit. The HVAC equipment may realize at least one of the functions of heating, ventilation, and air conditioning.

[0040] According to an embodiment of the present invention, the housing 100 of the HVAC outdoor unit 1 may include a top wall, a bottom wall, and side walls connected between the top and bottom walls. The side walls may include multiple walls. The top wall, bottom wall, and side walls cooperate to form a mounting cavity, and the fan is disposed within the mounting cavity of the housing 100. In practical applications, the bottom wall of the HVAC outdoor unit 1 is typically placed on a mounting surface, and an air outlet area 110 and an electrical area 120 are provided on an outer wall of the housing 100. The outer wall of the housing 100 may correspond to a side wall or a top side, without limitation.

[0041] The air outlet area 110 is provided with an air outlet 111. A fan is installed in the mounting cavity of the housing 100 and is located at the air outlet 111. The fan drives the gas to exchange heat with the heat exchanger of the HVAC equipment outdoor unit 1. The fan then guides the heat-exchanged gas out of the housing 100 through the air outlet 111. The electrical area 120 may be a mechanical cavity. Electrical components such as a maintenance panel, a controller, or a compressor may be installed in the electrical area 120 for performing maintenance operations on the HVAC equipment outdoor unit 1.

[0042] In addition, the first mesh cover 300 is disposed on the housing 100 and shields at least a portion of the air outlet area 110. The second mesh cover 400 is detachably disposed on the housing 100 and shields at least a portion of the electrical area 120.

[0043] It should be noted that the first mesh cover 300 blocks at least a portion of the air outlet area 110, which means that at least a portion of the orthographic projection of the air outlet area 110 on the plane where the first mesh cover 300 is located is located within the area surrounded by the outer contour of the first mesh cover 300, and the orthographic projection of the edge of the air outlet area 110 on the plane where the first mesh cover 300 is located may be located outside the area surrounded by the outer contour of the first mesh cover 300.

[0044] The second mesh cover 400 blocks at least a portion of the electrical area 120, which means that at least a portion of the orthographic projection of the electrical area 120 on the plane where the second mesh cover 400 is located is located within the area surrounded by the outer contour of the second mesh cover 400, and the orthographic projection of the edge of the electrical area 120 on the plane where the second mesh cover 400 is located may be located outside the area surrounded by the outer contour of the second mesh cover 400.

[0045] By setting the first mesh cover 300 and the second mesh cover 400 separately, whether the second mesh cover 400 is connected to the shell 100 or not will not affect the stable connection between the first mesh cover 300 and the shell 100. The first mesh cover 300 can reliably block at least a portion of the air outlet area 110. Under normal circumstances, the second mesh cover 400 is connected to the shell 100, and external objects and personnel will not come into contact with the electrical area 120, thereby ensuring the normal operation of the electrical components in the electrical area 120, reducing the probability of damage to the electrical components in the electrical area 120, and preventing personal injury.

[0046] When the HVAC equipment needs to be repaired, inspected, maintained, debugged and updated, the second mesh cover 400 can be removed from the shell 100. At this time, the maintenance personnel can operate the electrical area 120, thereby realizing the repair, inspection, maintenance, debugging and updating of the HVAC equipment. Moreover, since the first mesh cover 300 blocks the air outlet area 110, it is difficult for maintenance personnel and external objects to contact the fan regardless of whether the fan stops working. This not only avoids the fan from being damaged by collision when rotating, but also avoids people from being scratched when the fan rotates. Therefore, during the process of repair, inspection, maintenance, debugging and updating of the HVAC equipment, the fan can still be in working condition, ensuring the continuity of the operation of the HVAC equipment, and the staff can observe the operating status of the fan in real time, with high feedback timeliness, and the repair, inspection, maintenance, debugging and updating of the HVAC equipment are more accurate and rapid.

[0047] It should be noted that the electrical area 120 may be additionally provided with a cover plate or other structures. After the second mesh cover 400 is removed from the shell 100, the cover plate of the electrical area 120 is exposed. At this time, after the cover plate is removed, the electrical components in the electrical area 120 can be operated to further improve safety; or the electrical area 120 may not be additionally provided with a cover plate. After the second mesh cover 400 is removed from the shell 100, the electrical components in the electrical area 120 can be directly operated, reducing the operating steps and improving the convenience of operation.

[0048] By setting the first side panel 150, when the first side panel 150 is connected to the main body 140, the first side panel 150 extends beyond the above-mentioned outer wall of the main body 140, and when the second mesh cover 400 moves relative to the main body 140, the second mesh cover 400 will stop at the first side panel 150, so the second mesh cover 400 cannot be separated from the shell 100, thereby avoiding the second mesh cover 400 and the shell 100 from being separated by mistake during transportation. When the HVAC equipment outdoor unit 1 needs to be repaired, maintained, or updated, the first side panel 150 can be separated from the main body 140 first, and then the second mesh cover 400 can be moved relative to the main body 140 to achieve separation between the second mesh cover 400 and the main body 140, thereby achieving operation of the electrical area 120.

[0049] In this way, the first side plate 150 and the second mesh cover 400 form a double protection for the electrical area 120 , further ensuring that the second mesh cover 400 effectively shields the electrical area 120 , making it safer.

[0050] For example, as shown in Figures 10 and 12, a plug-in slider 151 is provided on the side of the first side panel 150 facing the main body 140, and the main body 140 is provided with a plug-in slot 141. The plug-in slider 151 is inserted into the plug-in slot 141 and can slide relative to the plug-in slot 141 in the vertical direction. When assembling between the first side panel 150 and the main body 140, the plug-in slider 151 is first inserted into the plug-in slot 141, and then the first side panel 150 moves upward (or downward) and the plug-in slider 151 stops at the inner surface of the main body 140. At this time, the horizontal position between the first side panel 150 and the main body 140 is fixed, and finally the first side panel 150 and the main body 140 may be fixed together by threaded fasteners.

[0051] In this way, the HVAC outdoor unit 1 according to the embodiment of the present invention defines the relative position between the housing 100 and the second mesh cover 400 by providing the first side plate 150 , thereby achieving both stable connection and convenient maintenance.

[0052] As shown in Figures 3-5 and 7, one of the first and second mesh covers 300 and 400 is provided with a positioning notch 310, and the other is provided with a positioning insert 410, which is inserted into the positioning notch 310. The positioning insert 410 can be configured on the second mesh cover 400, and the positioning notch 310 can be configured on the first mesh cover 300. This allows for pre-positioning of the first and second mesh covers 300 and 400, improving the assembly accuracy of the HVAC outdoor unit 1 and reducing assembly difficulty.

[0053] As shown in Figures 2, 7, 10 and 11, one of the second mesh cover 400 and the housing 100 is provided with a first plug-in portion 420 and the other is provided with a second plug-in portion 130, and the second mesh cover 400 is movable relative to the housing 100 between a plug-in position and a fixed position along the horizontal direction.

[0054] When the second mesh cover 400 is in the plug-in position, the first plug-in portion 420 and the second plug-in portion 130 are pluggably connected; when the second mesh cover 400 is in the fixed position, the first plug-in portion 420 and the second plug-in portion 130 are non-pluggably connected.

[0055] When the first side plate 150 is connected to the main body 140 , the second net cover 400 is limited to a fixed position; when the first side plate 150 is separated from the main body 140 , the second net cover 400 is movable between the plug-in position and the fixed position.

[0056] For example, the first plug-in portion 420 is provided on the second mesh cover 400. During the assembly process, the first plug-in portion 420 is first inserted into the second plug-in portion 130. At this time, the second mesh cover 400 is located in the plug-in position, and then the second mesh cover 400 is pushed to move horizontally to a fixed position. At this time, the first plug-in portion 420 cannot be pulled out from the second plug-in portion 130, and the relative position between the second mesh cover 400 and the main body 140 is fixed; during the disassembly process, the second mesh cover 400 is first moved horizontally from the fixed position to the plug-in position, and then the first plug-in portion 420 is pulled out from the second plug-in portion 130 to achieve separation between the second mesh cover 400 and the main body 140.

[0057] By setting the first plug-in part 420 and the second plug-in part 130, the connection and separation between the second mesh cover 400 and the main body 140 can be achieved, and since the second mesh cover 400 moves in the horizontal direction, that is, the second mesh cover 400 and the main body 140 will not move relative to each other in the vertical direction, or the relative position movable range between the second mesh cover 400 and the main body 140 is small, so that the first plug-in part 420 and the second plug-in part 130 will not move relative to each other in the vertical direction, or the relative position movable range between the first plug-in part 420 and the second plug-in part 130 is small. Therefore, the cooperation between the first plug-in part 420 and the second plug-in part 130 can support the second mesh cover 400 in the vertical direction to offset the gravity of the second mesh cover 400, and the second mesh cover 400 and the main body 140 are not easily moved relative to each other under the action of gravity, which facilitates the assembly between the second mesh cover 400 and the shell 100.

[0058] As shown in Figures 2, 7, and 10, there are multiple first plug-in connectors 420, and at least three of the multiple first plug-in connectors 420 are not located in a straight line. There are multiple second plug-in connectors 130, and at least three of the multiple second plug-in connectors 130 are not located in a straight line. The multiple first plug-in connectors 420 and the multiple second plug-in connectors 130 are connected in a one-to-one correspondence.

[0059] It should be noted that at least three of the plurality of first plug-in parts 420 are not located in the same straight line, which means that the three first plug-in parts 420 are arranged in a triangle. At least three of the plurality of second plug-in parts 130 are not located in the same straight line, which means that the three second plug-in parts 130 are arranged in a triangle.

[0060] In this way, multiple points of connection can be formed between the second mesh cover 400 and the shell 100, and the connection strength between the second mesh cover 400 and the shell 100 is increased. Moreover, since the multiple connection points between the second mesh cover 400 and the shell 100 are not located on the same straight line, the probability of relative deflection between the second mesh cover 400 and the shell 100 can be reduced, and the relative position stability between the second mesh cover 400 and the shell 100 is better.

[0061] As shown in FIG. 11 , the first plug-in portion 420 includes a connecting section 421 and an inserting section 422 .

[0062] The connecting section 421 is connected to the side of the second mesh cover 400 facing the main body 140 and extends toward the main body 140. The plug section 422 is connected to the connecting section 421 and extends horizontally from the connecting section 421 toward the first mesh cover 300. The second plug-in portion 130 is a slot and is configured on the side of the main body 140 facing the second mesh cover 400. When the second mesh cover 400 is in the insertion and removal position, the plug section 422 corresponds to the slot's notch. When the second mesh cover 400 is in the fixed position, the plug section 422 and the slot's notch are offset.

[0063] For example, connecting ribs may be provided between the connecting section 421 and the side of the second mesh cover 400 facing the main body 140 to increase the bending strength between the connecting section 421 and the second mesh cover 400. The plug section 422 and the connecting section 421 may be arranged perpendicularly to each other, forming an "L" shape between the plug section 422 and the connecting section 421. Connecting ribs may also be provided between the side of the plug section 422 facing away from the main body 140 and the connecting section 421 to increase the bending strength between the connecting section 421 and the plug section 422.

[0064] In addition, the cross-sectional area of ​​the slot opening is larger than the cross-sectional area of ​​the plug-in section 422, so the plug-in section 422 can enter the slot from the slot to place the second mesh cover 400 in the plug-in and unplug position, and then the connecting section 421 can move horizontally at the slot opening of the slot. When the second mesh cover 400 is in a fixed position, the plug-in section 422 is offset from the slot opening, so that the plug-in section 422 cannot be pulled out of the slot at this time to fix the relative position between the second mesh cover 400 and the shell 100.

[0065] As shown in FIG. 2 , the housing 100 further includes a second side plate 160 and a first fixing member.

[0066] The main body 140 also has a third direction (indicated by arrow C in the accompanying drawings). The first, second, and third directions are perpendicular to each other. The second side panel 160 is located on one side of the main body 140 in the third direction. The first fixing member is provided through the outer wall of the main body 140 and the second side panel 160. When the second mesh cover 400 is connected to the main body 140, the first fixing member corresponds to the position of the second mesh cover 400; when the second mesh cover 400 is separated from the main body 140, the first fixing member is exposed.

[0067] For example, after the HVAC outdoor unit 1 is installed, the first direction can be perpendicular to the wall, and the outer wall can be the outer wall of the main body 140 facing away from the wall. That is, the outer wall of the main body 140 facing away from the wall has the air outlet area 110 and the electrical area 120. The second direction can be horizontal and parallel to the wall. That is, the first side panel 150 is installed on the horizontal side of the main body 140. The third direction can be vertical, with the second side panel 160 installed on the upper side of the main body 140. The first fixing member can be a threaded fastener, such as a bolt or screw.

[0068] When the second mesh cover 400 is connected to the main body 140, the second mesh cover 400 can provide a certain shielding effect on the first fixing member, so that the first fixing member is not easily removed, thereby preventing the first fixing member from being accidentally removed. When the HVAC equipment outdoor unit 1 needs to be repaired, in some cases it is necessary to remove the second side panel 160 and repair the HVAC equipment outdoor unit 1 from the top. Since the second mesh cover 400 is detachably connected to the main body 140, the first fixing member can be easily removed after the second mesh cover 400 is removed from the main body 140, ensuring the ease of disassembly between the main body 140 and the second side panel 160, and taking into account both safety and ease of assembly and disassembly.

[0069] As shown in FIG. 3 to FIG. 5 , at least one of the first mesh cover 300 and the second mesh cover 400 is provided with a through hole 170 , and the first fixing member corresponds to the position of the through hole 170 .

[0070] It should be noted that the second side panel 160 and the main body 140 can be connected by multiple first fixing members, and the multiple first fixing members are arranged at intervals along the second direction. The position of a part of the multiple first fixing members corresponds to the position of the first mesh cover 300, and the position of another part of the multiple first fixing members corresponds to the position of the second mesh cover 400.

[0071] For example, only the first mesh cover 300 is provided with the through hole 170 , or only the second mesh cover 400 is provided with the through hole 170 , or both the first mesh cover 300 and the second mesh cover 400 are provided with the through hole 170 .

[0072] In this way, the first fixing member corresponding to the through hole 170 can be removed or installed through the through hole 170 without removing the first mesh cover 300 and the second mesh cover 400, which greatly reduces the difficulty of disassembling and assembling the second side plate 160 and the main body 140.

[0073] As shown in Figures 7, 8, 13, and 14, the HVAC outdoor unit 1 further includes a decorative block 430, which is rotatably connected to the wall of the through hole 170 between an open position and a closed position. When the decorative block 430 is in the open position, the first fixing member is exposed from the through hole 170; when the decorative block 430 is in the closed position, the through hole 170 is covered to conceal the first fixing member.

[0074] That is, when the decorative block 430 is in the open position, the through hole 170 is not blocked by the decorative block 430, and the user can remove and install the first fixing member corresponding to the through hole 170 through the through hole 170; when the decorative block 430 is in the closed position, the through hole 170 is covered, and the user cannot see the first fixing member through the through hole 170. On the one hand, the first fixing member will not be directly touched, which improves safety. On the other hand, in rainy or snowy weather, rain or snow will not easily come into contact with the first fixing member, which reduces the corrosion and aging rate of the first fixing member due to moisture and extends the service life of the first fixing member. In addition, the appearance of the HVAC equipment outdoor unit 1 is more neat.

[0075] As shown in Figures 8, 13, and 14, one of the decorative block 430 and the wall of the through hole 170 is provided with a rotating shaft 431, and the other is provided with a rotating groove 171. The rotating shaft 431 rotates within the rotating groove 171 and extends along the third direction. The rotating shaft 431 is located on the left side of the through hole 170. In other words, the rotation axis of the decorative block 430 is located on the left side of the decorative block 430, and the right side of the decorative block 430 has a greater range of motion relative to the wall of the through hole 170. This is more in line with the human body's force application method, making it easier for staff to switch the decorative block 430 between the open and closed positions.

[0076] As shown in Figures 8, 13 and 14, the outer surface of the decorative block 430 and one of the hole walls of the through hole 170 are provided with a damping protrusion 432. During the rotation of the decorative block 430, the outer surface of the decorative block 430 and the other hole wall of the through hole 170 contact to generate friction damping force.

[0077] That is to say, the force applied to the decorative block 430 must be greater than the friction damping force in order to drive the decorative block 430 from the open position to the closed position, or from the closed position to the open position, thereby avoiding accidental movement when the decorative block 430 is subjected to vibration force or other non-human external force, and ensuring that the decorative block 430 can only rotate when the operator applies force to the decorative block 430.

[0078] As shown in Figures 8, 13 and 14, when the outer surface of the decorative block 430 is provided with a damping protrusion 432, there are multiple damping protrusions 432, and the multiple damping protrusions 432 include a first damping protrusion 433 and a second damping protrusion 434, and the first damping protrusion 433 and the second damping protrusion 434 are arranged at intervals along the second direction.

[0079] In this way, the damping force on the decorative block 430 is evenly distributed along the second direction, which can improve the relative position stability between the decorative block 430 and the through hole 170 and further avoid the decorative block 430 from being opened or closed by mistake.

[0080] 8 , 13 and 14 , the first damping protrusions 433 are provided on opposite sides of the outer surface of the decorative block 430 in the third direction. The second damping protrusions 434 are provided on opposite sides of the outer surface of the decorative block 430 in the third direction.

[0081] In this way, the decorative block 430 is evenly stressed on two opposite sides in the third direction, which can avoid the problem of deflection of the decorative block 430 during rotation and ensure that the decorative block 430 rotates more smoothly.

[0082] As shown in Figure 14, the above-mentioned first damping protrusion 433 is closer to the rotation axis of the decorative block 430 than the second damping protrusion 434. When the decorative block 430 is in the closed position, the distance between the first damping protrusion 433 and the hole wall of the through hole 170 in the first direction is smaller than the distance between the second damping protrusion 434 and the hole wall of the through hole 170 in the first direction, so that when the decorative block 430 rotates from the closed position to the open position, the first damping protrusion 433 contacts the hole wall of the through hole 170 before the second damping protrusion 434.

[0083] In this way, when the decorative block 430 is rotated from the closed position to the open position, the friction damping force applied to the decorative block 430 gradually increases from small to large. Therefore, it can ensure that the decorative block 430 is subjected to sufficient friction damping force during the rotation process to effectively prevent the decorative block 430 from being accidentally opened, and it can also reduce the exertion of the staff during the entire rotation process, making the operator more labor-saving.

[0084] As shown in FIG. 7 and FIG. 8 , the hole wall of the through hole 170 includes a ring edge 172 .

[0085] The ring edge 172 is arranged on the side of at least one of the first mesh cover 300 and the second mesh cover 400 facing the shell 100, and the ring edge 172 surrounds the through hole 170. The ring edge 172 is provided with an avoidance gap 173, the decorative block 430 is in the closed position, and the damping protrusion 432 is located in the avoidance gap 173.

[0086] By setting the avoidance notch 173, when the decorative block 430 is in the closed position, the damping protrusion 432 can be located in the avoidance notch 173, thereby avoiding continuous friction damping force between the decorative block 430 and the hole wall of the through hole 170, thereby reducing the probability of the hole wall of the through hole 170 and the decorative block 430 being damaged by force, and extending the service life of the through hole 170 and the decorative block 430.

[0087] In some embodiments of the present invention, the avoidance gap 173 can be connected to the rotation groove 171. During the process of rotating the decorative block 430 from the closed position to the open position, the rotating shaft 431 can move from the rotation groove 171 to the avoidance gap 173 to expand the movement range of the decorative block 430.

[0088] As shown in Figures 5, 6, 13 and 14, one of the hole wall of the through hole 170 and the outer surface of the decorative block 430 is provided with a positioning block 174 and the other is provided with a positioning groove 435. When the decorative block 430 is in the closed position, the positioning block 174 is located in the positioning groove 435.

[0089] In this way, in the process of the decorative block 430 moving from the open position to the closed position, the positioning block 174 gradually enters the positioning groove 435, and the positioning block 174 can stop at the groove wall of the positioning groove 435, thereby positioning the decorative block 430 in the closed position, preventing the decorative block 430 from being too close to the shell 100, and ensuring that the decorative block 430 effectively closes the through hole 170 and effectively blocks the first fixing member.

[0090] As shown in Figures 5, 6, 13, and 14, the positioning grooves 435 are provided on opposite sides of the decorative block 430 in the third direction. The positioning blocks 174 are provided on opposite side walls of the through hole 170 in the third direction. This ensures that when the decorative block 430 moves from the open position to the closed position, the decorative block 430 is evenly stressed in the third direction, preventing the decorative block 430 from deflecting or other problems.

[0091] In addition, the cross-sectional area of ​​the positioning block 174 gradually decreases from the closed position to the open position, and the positioning block 174 can play a guiding role. The end of the positioning block 174 facing away from the shell 100 is more easily inserted into the positioning groove 435, thereby preventing the positioning block 174 from colliding with the groove wall of the positioning groove 435, and the rotation of the decorative block 430 is smoother.

[0092] As shown in Figures 5, 6, 13 and 14, the hole wall of the above-mentioned through hole 170 is provided with a limit block 175, and the limit block 175 is located on the side of the through hole 170 away from the rotation axis of the decorative block 430 in the second direction; the decorative block 430 is provided with an inclined surface 437 for avoiding the limit block 175, and when the decorative block 430 is in the closed position, the inclined surface 437 stops at the limit block 175.

[0093] By setting the cooperation between the limit block 175 and the inclined surface 437, on the one hand, the decorative block 430 can be prevented from excessively rotating toward the direction close to the main body 140. On the other hand, by setting the inclined surface 437 to avoid the limit block 175, the thickness of the end of the decorative block 430 away from its rotation axis can be reduced, thereby reducing the probability of the decorative block 430 colliding with the hole wall of the through hole 170 during rotation, and improving the smoothness of the rotation of the decorative block 430.

[0094] As shown in Figures 5, 6, 13, and 14, the decorative block 430 is provided with a first rib 436 on the side facing away from the housing 100. The second mesh cover 400 is provided with a second rib 440 and a third rib 441 on the side facing away from the housing 100. The second rib 440 and the third rib 441 are located on opposite sides of the through hole 170. When the decorative block 430 is in the closed position, the first rib 436, the second rib 440, and the third rib 441 are located on the same plane or curved surface.

[0095] For example, the first rib 436 can be one or more. If there are multiple first ribs 436, the multiple first ribs 436 are arranged at intervals along the first direction, each first rib 436 extends along the second direction, and the second rib 440 and the third rib 441 are located on opposite sides of the through hole 170 in the second direction; or the multiple first ribs 436 are arranged at intervals along the second direction, each first rib 436 extends along the first direction, and the second rib 440 and the third rib 441 are located on opposite sides of the through hole 170 in the first direction.

[0096] That is to say, when the decorative block 430 is in the closed position, the first rib 436, the second rib 440 and the third rib 441 can be connected into a complete rib, ensuring the uniformity of the appearance of the HVAC equipment outdoor unit 1 and improving the aesthetics of the HVAC equipment outdoor unit 1.

[0097] In addition, the first rib 436 may extend along a straight line or a curved line.

[0098] As shown in FIG. 5 to FIG. 8 , the HVAC equipment outdoor unit 1 further includes a second fixing member.

[0099] The second mesh cover 400 is provided with a plurality of through holes 170, at least one of the plurality of through holes 170 is staggered with the first fixing member, a fixing plate 450 is provided on the side of the second mesh cover 400 facing the shell 100, the fixing plate 450 corresponds to the position of at least one of the plurality of through holes 170, and the second fixing member is passed through the fixing plate 450 and the main body 140.

[0100] For example, the second fixing member can be a threaded fastener, such as a bolt or a screw. By providing the second fixing member, the relative position between the second mesh cover 400 and the housing 100 can be fixed. When the second mesh cover 400 is connected to the housing 100, the decorative block 430 is in the open position, and the through hole 170 is not blocked by the decorative block 430. The user can remove and install the second fixing member corresponding to the through hole 170 through the through hole 170. When the decorative block 430 is in the closed position, the through hole 170 can be covered, and the user cannot observe the second fixing member through the through hole 170. On the one hand, the second fixing member will not be directly touched, which improves safety. On the other hand, in rainy or snowy weather, rain or snow will not easily come into contact with the second fixing member, reducing the corrosion and aging rate of the second fixing member due to moisture, thereby extending the service life of the first fixing member. In addition, the HVAC equipment outdoor unit 1 has a cleaner appearance.

[0101] In some embodiments of the present invention, the first fixing member may be provided through the fixing plate 450 , the main body 140 and the second side plate 160 to reduce the number of parts and lower the cost.

[0102] In another embodiment, as shown in Figures 15 to 21, the first and second mesh covers 300 and 400 of the HVAC equipment outdoor unit 1 according to an embodiment of the present invention are integrally formed to form an integral mesh cover, and the integral mesh cover 500 is slidably disposed on the housing 100 between a first position and a second position. When the integral mesh cover 500 is in the first position, it blocks at least a portion of the air outlet area 110 and at least a portion of the electrical area 120; when the integral mesh cover 500 is in the second position, at least a portion of the electrical area 120 blocked by the integral mesh cover 500 in the first position is offset from the integral mesh cover 500 in the sliding direction of the integral mesh cover 500.

[0103] According to the HVAC equipment outdoor unit 1 of the embodiment of the present invention, the shell 100 may include a top wall, a bottom wall, and a side wall connected between the top wall and the bottom wall. The side wall may include a plurality of side walls. The top wall, the bottom wall, and the side walls cooperate to form a mounting cavity. The fan is arranged in the mounting cavity of the shell 100. In actual applications, the bottom wall of the HVAC equipment outdoor unit 1 is usually placed on the mounting surface. Then, an air outlet area 110 and an electrical area 120 are provided on an outer wall of the shell 100. The above-mentioned outer wall of the shell 100 may correspond to the side wall or the top side, and there is no limitation to this. The air outlet area 110 is provided with an air outlet 111. The fan is arranged in the mounting cavity of the shell 100 and is located at the air outlet 111. The fan can drive the gas to exchange heat with the heat exchanger of the HVAC equipment outdoor unit 1. The fan then guides the gas after heat exchange to be discharged from the shell 100 through the air outlet 111. The electrical area 120 may be a mechanical cavity, and the electrical area 120 may be installed with electrical structures, such as a maintenance panel, a controller, or electrical components such as a compressor, for performing maintenance operations on the outdoor unit 1 of the HVAC equipment.

[0104] Furthermore, the integral mesh cover 500 is slidably disposed on the housing 100 and slides between a first position and a second position. When the integral mesh cover 500 is in the first position, it blocks at least a portion of the air outlet area 110 and at least a portion of the electrical area 120. When the integral mesh cover 500 is in the second position, at least a portion of the electrical area 120 that was blocked when the integral mesh cover 500 was in the first position is offset from the integral mesh cover 500 in the sliding direction of the integral mesh cover 500.

[0105] It should be noted that when the overall mesh cover 500 is in the first position, it blocks the air outlet area 110 and the electrical area 120, which means that when the overall mesh cover 500 is in the first position, at least a part of the orthographic projection of the air outlet area 110 on the plane where the overall mesh cover 500 is located and at least a part of the orthographic projection of the electrical area 120 on the plane where the overall mesh cover 500 is located are located in the area surrounded by the outline of the overall mesh cover 500, wherein the orthographic projection of the air outlet 111 on the plane where the overall mesh cover 500 is located is located in the area surrounded by the outline of the overall mesh cover 500, and the orthographic projections of the edges of the air outlet area 110 and the edges of the electrical area 120 on the plane where the overall mesh cover 500 may be located in the area surrounded by the outline of the overall mesh cover 500. outside the area blocked; when the integral mesh cover 500 is in the second position, at least a portion of the area blocked by the electrical zone 120 at the first position of the integral mesh cover 500 is staggered with the integral mesh cover 500 in the sliding direction of the integral mesh cover 500, which means that when the integral mesh cover 500 is in the second position, at least a portion of the electrical zone 120 is blocked at the first position of the integral mesh cover 500, and the orthographic projection of all or a portion of the at least a portion of the area blocked by the electrical zone 120 on the plane where the integral mesh cover 500 is located is outside the area surrounded by the outline of the integral mesh cover 500. The operator can operate on the area of ​​the electrical zone 120 that is not blocked by the integral mesh cover 500 to repair the outdoor unit 1 of the HVAC equipment.

[0106] When the integral mesh cover 500 is in the first position, it blocks at least a portion of the air outlet area 110 and at least a portion of the electrical area 120. At this time, external objects or personnel can be blocked by the integral mesh cover 500 and will not come into contact with the air outlet area 110 and the electrical area 120, or can come into contact with a smaller area of ​​the air outlet area 110 and a smaller area of ​​the electrical area 102. On the one hand, external objects, clothing of personnel, and body parts such as hands are not easy to come into contact with the fan through the air outlet 111, thereby preventing the fan from being damaged by collision when the fan rotates, and also preventing personnel from being scratched when the fan rotates. On the other hand, external objects and personnel will not come into contact with the electrical area 120, thereby ensuring the normal operation of the electrical components in the electrical area 120, reducing the probability of damage to the electrical components in the electrical area 120, and preventing personal injury.

[0107] When the integral mesh cover 500 is in the second position, at least a portion of the area blocked by the electrical zone 120 at the first position of the integral mesh cover 500 is offset from the sliding direction of the integral mesh cover 500. At this time, at least a portion of the area blocked by the electrical zone 120 at the first position of the integral mesh cover 500 is not blocked by the integral mesh cover 500. The staff can operate the electrical components (such as the maintenance panel) in the electrical zone 120 through the above-mentioned at least a portion of the electrical zone 120 to perform maintenance, debugging, updating and inspection on the HVAC equipment outdoor unit 1.

[0108] It should be noted that the electrical area 120 can be additionally provided with a cover plate and other structures. When the overall mesh cover 500 is in the second position, the cover plate of the electrical area 120 is exposed. At this time, the cover plate is removed and the electrical components in the electrical area 120 are operated to further improve safety; or the controller 120 can also be provided with no additional cover plate. When the overall mesh cover 500 is in the second position, the electrical components in the electrical area 120 can be directly operated, reducing the operating steps and improving the convenience of operation.

[0109] In this way, the HVAC equipment outdoor unit 1 according to the embodiment of the present invention can not only shield the fan and the electrical area 120 by switching the position of the integral mesh cover 500 to improve safety, but also facilitate the operation of electrical components in the electrical area 120.

[0110] According to some specific embodiments of the present invention, as shown in FIG16 , when the integral mesh cover 500 is in the second position, it blocks at least a portion of the air outlet 111. When the integral mesh cover 500 is in the second position, the orthographic projection of most or all of the air outlet 111 on the plane where the integral mesh cover 500 is located is within the area surrounded by the outline of the integral mesh cover 500. In other words, when the integral mesh cover 500 is in the second position, it still blocks most or all of the air outlet 111.

[0111] When the electrical components in the electrical area 120 are in operation, the fan may also be rotating. Therefore, the overall mesh cover 500 still covers most or all of the air outlet 111. External objects or personnel can be blocked by the overall mesh cover 500 and are not easily exposed to the air outlet 111. External objects, staff's clothes, hands and other body parts are not easy to contact the fan through the air outlet 111, which avoids the fan being damaged by collision when rotating, and also avoids the staff being scratched when the fan rotates.

[0112] According to some specific embodiments of the present invention, as shown in Figures 19 and 21, a first stopper is provided on the outer wall of the housing 100, and a second stopper is provided on the side of the integral mesh cover 500 facing the housing 100. The first stopper and the second stopper cooperate to limit the sliding travel of the integral mesh cover 500. The cooperation between the first stopper and the second stopper prevents the integral mesh cover 500 from separating from the housing 100 in its sliding direction, thereby preventing separation between the housing 100 and the integral mesh cover 500. The operator does not need to control the force and duration of the force application, thereby improving ease of use.

[0113] According to some specific embodiments of the present invention, as shown in Figures 18 and 21, the first limiting member includes a first limiting protrusion 180 and a second limiting protrusion 190, and the second limiting member is a third limiting protrusion 520. The third limiting protrusion 520 can be located between the first limiting protrusion 180 and the second limiting protrusion 190 in the sliding direction of the overall mesh cover 500; wherein, when the overall mesh cover 500 is in the first position, the third limiting protrusion 520 stops at the first limiting protrusion 180; when the overall mesh cover 500 is in the second position, the third limiting protrusion 520 stops at the second limiting protrusion 190.

[0114] That is to say, during the sliding process of the overall mesh cover 500, if the third limiting protrusion 520 stops at the first limiting protrusion 180, the overall mesh cover 500 is in the first position, and at this time, the third limiting protrusion 520 and the second limiting protrusion 190 are spaced apart; if the third limiting protrusion 520 stops at the second limiting protrusion 190, the overall mesh cover 500 is in the second position, and at this time, the third limiting protrusion 520 and the first limiting protrusion 180 are spaced apart.

[0115] Through the mutual cooperation between the first limiting protrusion 180, the second limiting protrusion 190 and the third limiting protrusion 520, the overall mesh cover 500 can be prevented from accidentally detaching from the shell 100 due to excessive force during the sliding process, thereby ensuring the structural reliability of the HVAC equipment outdoor unit 1 and limiting the sliding range of the overall mesh cover 500.

[0116] Specifically, the first limiting protrusion 180 can be located on the side of the electrical area 120 facing away from the air outlet area 110, ensuring that the electrical area 120 is largely shielded by the overall mesh cover 500 when the overall mesh cover 500 is in the first position. The third limiting protrusion 520 is located on the side of the overall mesh cover 500 facing the first limiting protrusion 180, maximizing the area of ​​the overall mesh cover 500 and saving costs. The second limiting protrusion 190 can be located at the junction between the air outlet area 110 and the electrical area 120, ensuring that the electrical area 120 is largely shielded by the overall mesh cover 500 when the overall mesh cover 500 is in the second position, facilitating operation of electrical components within the electrical area 120.

[0117] According to some specific embodiments of the present invention, as shown in Figures 18 and 21, the first limiting protrusion 180 is provided with a first fixing hole 181. When the integral mesh cover 500 is in the first position, the first fixing member passing through the first fixing hole 181 is detachably connected to the third limiting protrusion 520. The first fixing member can be a threaded fastener, such as a bolt or a screw, and the third limiting protrusion 520 can be provided with a threaded hole. After passing through the first fixing hole 181, the first fixing member is threadedly connected to the threaded hole of the third limiting protrusion 520, or the first fixing member can be clamped to the third limiting protrusion 520 by passing through the first fixing hole 181.

[0118] By setting a first fixing part, the overall mesh cover 500 can be fixed in the first position, preventing the overall mesh cover 500 from sliding relative to the shell 100 without human operation, ensuring the positioning reliability between the overall mesh cover 500 and the shell 100, which is beneficial to reducing the probability of accidental exposure of the electrical area 120 and preventing the overall mesh cover 500 from being damaged by collision during the handling and transportation of the HVAC equipment outdoor unit 1.

[0119] According to some specific embodiments of the present invention, as shown in Figures 18 and 21, the outer wall of the housing 100 is provided with a first fixing protrusion 1100. The first fixing protrusion 1100 and the first limiting protrusion 180 are located on opposite sides of the housing 100 in the sliding direction of the integral mesh cover 500. A second fixing protrusion 530 is provided on the side of the integral mesh cover 500 facing the housing 100. The second fixing protrusion 530 is located on the side of the first fixing protrusion 1100 facing away from the first limiting protrusion 180. The second fixing protrusion 530 is provided with a second fixing hole 531. When the integral mesh cover 500 is in the first position, the second fixing member passing through the second fixing hole 531 is detachably connected to the first fixing protrusion 1100.

[0120] For example, the second fixing member can be a threaded fastener, such as a bolt or a screw, and the first fixing protrusion 1100 can be provided with a threaded hole. The second fixing member can be threadedly connected to the threaded hole of the first fixing protrusion 1100 after passing through the second fixing hole 531, or the second fixing member can be snap-fitted to the first fixing protrusion 1100 after passing through the second fixing hole 531. In addition, the second fixing protrusion 530 and the third limiting protrusion 520 can be integrally formed with the overall mesh cover 500, and the size of the second fixing protrusion 530 in the axial direction of the air outlet 111 and the size of the third limiting protrusion 520 in the axial direction of the air outlet 111 can be the same.

[0121] The coordination between the first fixing protrusion 1100 and the second fixing protrusion 530 more reliably secures the entire mesh cover 500 in the first position, effectively preventing the mesh cover 500 from sliding relative to the housing 100 without human intervention. Furthermore, the first fixing protrusion 1100 and the first position-limiting protrusion 180 are located on opposite sides of the housing 100 in the sliding direction of the entire mesh cover 500, ensuring more uniform force across the entire mesh cover 500 when in the first position. Furthermore, the second fixing protrusion 530 is located on the side of the first fixing protrusion 1100 facing away from the first position-limiting protrusion 180. As the entire mesh cover 500 slides from the first position to the second position, the first fixing protrusion 1100 does not interfere with the second fixing protrusion 300, ensuring smooth movement of the entire mesh cover 500.

[0122] According to some specific embodiments of the present invention, as shown in Figures 14 to 18, the sliding direction of the overall mesh cover 500, the axial direction of the air outlet 111 and the height direction of the HVAC equipment outdoor unit 1 are perpendicular to each other, and the air outlet area 110 and the electrical area 120 are arranged along the sliding direction of the overall mesh cover 500.

[0123] It should be noted that the direction indicated by arrow A in the accompanying drawings is the axial direction of the air outlet 111, the direction indicated by arrow B is the sliding direction of the integral mesh cover 500, and the direction indicated by arrow C is the height direction of the HVAC equipment outdoor unit 1.

[0124] Specifically, after the HVAC equipment outdoor unit 1 is installed, for personnel facing the above-mentioned outer wall of the HVAC equipment outdoor unit 1, the sliding direction of the overall mesh cover 500 can be the left and right direction of the shell 100, the height direction of the HVAC equipment outdoor unit 1 can be the up and down direction of the shell 100, and the axial direction of the air outlet 111 can be the front and back direction of the shell 100.

[0125] In this way, the sliding direction of the integral mesh cover 500 is more consistent with the force exerted by human hands, thereby making it easier for operators to push and pull the integral mesh cover 500.

[0126] According to some specific embodiments of the present invention, as shown in Figures 18 to 21, the above-mentioned outer wall of the shell 100 is provided with a first limiting structure 1200, and the integral mesh cover 500 is provided with a second limiting structure 510. The first limiting structure 1200 and the second limiting structure 510 slide together to limit the relative position of the integral mesh cover 500 and the shell 100.

[0127] For example, the first limiting structure 1200 and the second limiting structure 510 are located above or below the air outlet area 110 and the electrical area 120 , or the first limiting structure 1200 and the second limiting structure 510 are provided above and below.

[0128] By setting the cooperation of the first limiting structure 1200 and the second limiting structure 510, not only can the relative sliding of the overall mesh cover 500 and the shell 100 in a preset direction be limited, but also the relative position between the overall mesh cover 500 and the shell 100 can be limited. The overall mesh cover 500 is not easy to separate from the shell 100, thereby improving the convenience of operation.

[0129] It should be noted that the first limiting structure 1200 can be located above the air outlet area 110 and the electrical area 120. Under the action of gravity, the overall mesh cover 500 can naturally droop so that the first limiting structure 1200 and the second limiting structure 510 can be reliably matched, and the overall mesh cover 500 is not easy to flip downward relative to the shell 100, which can ensure that the overall mesh cover 500 is stably fixed to the shell 100.

[0130] According to some specific embodiments of the present invention, as shown in FIG. 18 to FIG. 21 , the first limiting structure 1200 includes a first connecting section 1210 , a bending section 1220 and a first limiting section 1230 .

[0131] The first connecting section 1210 is connected to the above-mentioned outer wall of the shell 100 and is arranged along the height direction of the outdoor unit 1 of the HVAC equipment, the bending section 1220 is connected to the upper side of the first connecting section 1210 and extends in the direction away from the shell 100, and the first limiting section 1230 is connected to the side of the bending section 1220 away from the shell 100 and extends upward, wherein at least a portion of the second limiting structure 510 is located between the first limiting section 1230 and the shell 100 in the axial direction of the air outlet 111.

[0132] For example, the first connecting section 1210, the bent section 1220, and the first limiting section 1230 can be integrally formed. Furthermore, the first connecting section 1210 and the housing 100 can be connected via threaded fasteners. The first connecting section 1210 can be attached to the housing 100 to increase the contact area between the housing 100 and the first limiting structure 1200, thereby ensuring the connection strength between the housing 100 and the first limiting structure 1200.

[0133] At least a portion of the second limiting structure 510 is placed between the first limiting section 1230 and the shell 100. In this way, when the integral mesh cover 500 and the shell 100 move away from each other along the axial direction of the air outlet 111, the second limiting structure 510 and the first limiting section 1230 will abut against each other, thereby limiting the relative position between the integral mesh cover 500 and the shell 100 in the axial direction of the air outlet 111, and preventing the integral mesh cover 500 from falling off the shell 100.

[0134] According to some specific embodiments of the present invention, as shown in FIG. 17 and FIG. 19 , the second limiting structure 510 includes a second connecting section 511 and a second limiting section 512 .

[0135] One side of the second connecting section 511 is connected to the side of the integral mesh cover 500 facing the shell 100, and the second limiting section 512 is connected to the side of the second connecting section 511 facing the shell 100 and extends downward. The second limiting section 512 is located between the first limiting section 1230 and the shell 100 in the axial direction of the air outlet 111.

[0136] In which, the second limiting structure 510 can be integrally formed with the overall mesh cover 500, and the second connecting section 511 can be supported on the upper side of the first limiting section 1230, or the second limiting section 512 can be supported on the bending section 1220 to limit the relative position of the overall mesh cover 500 and the shell 100 in the height direction of the HVAC equipment outdoor unit 1.

[0137] In this way, through the mutual cooperation between the first limiting section 1230 and the second limiting section 512, when the overall mesh cover 500 moves away from each other along the axial direction of the air outlet 111, the relative position between the overall mesh cover 500 and the shell 100 in the axial direction of the air outlet 111 can be limited, thereby preventing the overall mesh cover 500 from falling off the shell 100.

[0138] Furthermore, when the integral mesh cover 500 is moved upward relative to the housing 100, the second limiting section 512 can be higher than the first limiting section 1230, and the integral mesh cover 500 can now be removed from the housing 100 for cleaning, repair, or replacement. When the integral mesh cover 500 is moved downward relative to the housing 100, the second limiting section 512 is inserted between the first limiting section 1230 and the housing 100, and the integral mesh cover 500 can now be fixed to the housing 100.

[0139] According to some specific embodiments of the present invention, as shown in FIG17 , the first position-limiting structure 1200 further includes a support segment 1240. The support segment 1240 is connected to the upper side of the first position-limiting segment 1230 and extends away from the housing 100. The support segment 1240 is supported on the lower surface of the second position-limiting segment 512. The second position-limiting segment 512 is provided with a third fixing hole 513, and a third fixing member passing through the third fixing hole 513 is connected to the support segment 1240.

[0140] For example, the third fixing member can be a threaded fastener, such as a bolt or a screw, and the support section 1240 can be provided with a threaded hole. The third fixing member passes through the third fixing hole 513 and is threadedly connected to the threaded hole of the support section 1240, or the third fixing member passes through the third fixing hole 513 and can be clamped with the support section 1240.

[0141] By setting the support section 1240, on the one hand, the contact area between the first limiting structure 1200 and the overall mesh cover 500 can be increased to improve the limiting effect. On the other hand, the relative position between the support section 1240 and the second limiting section 512 can be fixed by the third fixing member, thereby achieving the fixation of the relative position between the shell 100 and the overall mesh cover 500.

[0142] Furthermore, the third limiting protrusion 520 is lower than the support section 1240 in the height direction of the HVAC equipment outdoor unit 1, preventing interference between the third limiting protrusion 520 and the support section 1240 when the integral mesh cover 500 slides. The highest point of the second fixing protrusion 530 in the height direction of the HVAC equipment outdoor unit 1 can be higher than the lowest point of the support section 1240. When the integral mesh cover 500 is in the first position, the second fixing protrusion 530 can abut against the support section 1240 to achieve a limiting effect.

[0143] According to some specific embodiments of the present invention, as shown in Figures 17 and 18, a second limiting protrusion 190 is provided on at least one of the lower side of the support section 1240 and the side of the first limiting section 1230 facing the integral mesh cover 500, and a third limiting protrusion 520 is provided on the side of the integral mesh cover 500 facing the housing 100. When the integral mesh cover 500 is in the second position, the third limiting protrusion 520 abuts against the second limiting protrusion 190; when the integral mesh cover 500 is in the first position, the third limiting protrusion 520 is spaced apart from the second limiting protrusion 190.

[0144] That is to say, the second limiting protrusion 190 is arranged on the side of the first limiting section 1230 facing the overall mesh cover 500, or the second limiting protrusion 190 is arranged on the lower side of the supporting section 1240, or the second limiting protrusion 190 is arranged on both the side of the first limiting section 1230 facing the overall mesh cover 500 and the lower side of the supporting section 1240.

[0145] Through the cooperation between the second limiting protrusion 190 and the third limiting protrusion 520, the overall mesh cover 500 can be limited to the second position when the overall mesh cover 500 slides and will not be separated from the shell 100. The second limiting protrusion 190 and the first limiting structure 1200 can be formed as one piece, which is beneficial to reduce processing difficulty and improve structural strength. Compared with the air outlet area 110 and the electrical area 120, the support section 1240 and the first limiting section 1230 are closer to the overall mesh cover 500. Therefore, a second limiting protrusion 190 is provided on at least one of the support section 1240 and the first limiting section 1230. The axial size of the second limiting protrusion 190 in the air outlet 111 can be reduced, thereby reducing costs. In addition, during the transportation, production and handling of the shell 100, the second limiting protrusion 190 is less likely to interfere with other objects.

[0146] In some specific embodiments of the present invention, as shown in Figures 19 and 20, the third limiting protrusion 520 can be provided with a plurality of first weight-reducing holes 521 arranged at intervals along the height direction of the HVAC equipment outdoor unit 1, the second fixing protrusion 530 can be provided with a plurality of second weight-reducing holes 532 arranged at intervals along the height direction of the HVAC equipment outdoor unit 1, and the second connecting section 511 can be provided with a plurality of third weight-reducing holes 514 arranged at intervals along the sliding direction of the overall mesh cover 500.
