[0047] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0048] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0049] In the description of the present invention, "plurality" means two or more.

[0050] The following describes a HVAC equipment outdoor unit 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0051] like Figure 1 , Figure 2 and Fig. 9 As shown, the HVAC equipment 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 .

[0052] The housing 100 includes a main body 140 and a first side plate 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. The air outlet area 110 is provided with an air outlet 111. The first side plate 150 is detachably connected to one side of the main body 140 in the second direction. The fan is arranged in the housing 100 and located at the air outlet 111, that is, the fan corresponds to the air outlet 111. The first mesh cover 300 is arranged in the main body 140 and blocks at least a part of the air outlet area 110. The second mesh cover 400 is detachably arranged in the main body 140 and blocks at least a part 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 that is opposite to the first mesh cover 300 in the second direction.

[0053] 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 in 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.

[0054] 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, and the HVAC equipment may realize at least one of the functions including heating, ventilation, and air conditioning.

[0055] According to the HVAC equipment outdoor unit 1 of the embodiment of the present invention, the housing 100 may have a top wall, a bottom wall, and a side wall connected between the top wall and the bottom wall, and the side wall may include a plurality of them, and the top wall, the bottom wall, and the side wall cooperate to form a mounting cavity, and the fan is arranged in the mounting cavity of the housing 100. In practical applications, the bottom wall of the HVAC equipment outdoor unit 1 is usually placed on the mounting surface, and an air outlet area 110 and an electrical area 120 are arranged on an outer wall of the housing 100, and the outer wall of the housing 100 may correspond to the side wall or the top side, and there is no limitation on this.

[0056] The air outlet area 110 is provided with an air outlet 111, and the fan is arranged in the installation cavity of the housing 100 and is located at the air outlet 111. The fan can drive the gas to exchange heat with the heat exchanger of the outdoor unit 1 of the HVAC equipment, and the fan then guides the gas after the heat exchange to be discharged from the housing 100 through the air outlet 111. Among them, the electrical area 120 can be a mechanical cavity, and the electrical area 120 can be installed with electrical structures, such as maintenance panels, controllers or compressors and other electrical parts, for performing operations such as maintenance on the outdoor unit 1 of the HVAC equipment.

[0057] 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.

[0058] 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.

[0059] The second mesh cover 400 blocks at least a portion of the electrical zone 120, which means that at least a portion of the orthographic projection of the electrical zone 120 on the plane where the second mesh cover 400 is located is located in the area surrounded by the outer contour of the second mesh cover 400, and the orthographic projection of the edge of the electrical zone 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.

[0060] 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, and the first mesh cover 300 can reliably block at least a part 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 injuries.

[0061] 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. In addition, since the first mesh cover 300 blocks the air outlet area 110, it is not easy for maintenance personnel and external objects to contact the fan regardless of whether the fan stops working. This not only avoids damage to the fan caused by collision when it rotates, 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 timeliness of feedback, and the repair, inspection, maintenance, debugging and updating of the HVAC equipment are more accurate and rapid.

[0062] It should be noted that the electrical area 120 may be additionally provided with a cover plate and 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, the cover plate is removed and the electrical components in the electrical area 120 can be operated to further improve safety. Alternatively, 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.

[0063] 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 exceeds 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 with 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.

[0064] 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, which is safer.

[0065] For example, Fig.10 and Fig.12 As shown, 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 position between the first side panel 150 and the main body 140 in the horizontal direction is fixed, and finally the first side panel 150 and the main body 140 may be fixed together by threaded fasteners.

[0066] In this way, the HVAC equipment 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 taking into account both stable connection and convenient maintenance.

[0067] like Figure 3-Figure 5 as well as Figure 7As shown, one of the first mesh cover 300 and the second mesh cover 400 is provided with a positioning notch 310 and the other is provided with a positioning plug-in 410, and the positioning plug-in 410 is inserted into the positioning notch 310. The positioning plug-in 410 can be configured on the second mesh cover 400, and the positioning notch 310 can be configured on the first mesh cover 300. In this way, the pre-positioning between the first mesh cover 300 and the second mesh cover 400 can be achieved, thereby improving the assembly accuracy of the outdoor unit 1 of the HVAC equipment and reducing the assembly difficulty.

[0068] like Figure 2 , Figure 7 , Fig.10 and Fig.11 As shown, 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 in a horizontal direction.

[0069] When the second mesh cover 400 is located at 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 located at the fixed position, the first plug-in portion 420 and the second plug-in portion 130 are non-pluggably connected.

[0070] When the first side plate 150 is connected to the main body 140 , the second net cover 400 is limited in 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.

[0071] For example, the first plug-in portion 420 is arranged 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 the separation between the second mesh cover 400 and the main body 140.

[0072] 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 realized, and because 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 easy to move relative to each other under the action of gravity, which facilitates the assembly between the second mesh cover 400 and the shell 100.

[0073] like Figure 2 , Figure 7 and Fig.10 As shown, there are multiple first plug-in parts 420, at least three of which are not located in the same straight line. There are multiple second plug-in parts 130, at least three of which are not located in the same straight line, and the multiple first plug-in parts 420 and the multiple second plug-in parts 130 are connected one by one.

[0074] 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.

[0075] In this way, multi-point connection can be formed between the second mesh cover 400 and the shell 100, the connection strength between the second mesh cover 400 and the shell 100 is improved, and because 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.

[0076] like Fig.11 As shown, the first plug-in portion 420 includes a connecting section 421 and an plug-in section 422 .

[0077] The connecting section 421 is connected to the side of the second mesh cover 400 facing the main body 140, and the connecting section 421 extends in a direction close to the main body 140. The plug section 422 is connected to the connecting section 421, and the plug section 422 extends from the connecting section 421 in a horizontal direction toward the direction close to 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 plug-in position, the plug section 422 corresponds to the slot position of the slot, and when the second mesh cover 400 is in the fixed position, the plug section 422 is staggered from the slot position of the slot.

[0078] For example, the connecting section 421 and the side of the second mesh cover 400 facing the main body 140 may be provided with connecting ribs to increase the bending strength between the connecting section 421 and the second mesh cover 400. The plug-in section 422 and the connecting section 421 may be vertically arranged to form an "L" shape between the plug-in section 422 and the connecting section 421, and the side of the plug-in section 422 facing away from the main body 140 and the connecting section 421 may also be provided with connecting ribs to increase the bending strength between the connecting section 421 and the plug-in section 422.

[0079] 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 opening 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 of the slot, so 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.

[0080] like Figure 2 As shown, the housing 100 further includes a second side plate 160 and a first fixing member.

[0081] The main body 140 also has a third direction (the direction indicated by arrow C in the figure), the first direction, the second direction and the third direction are perpendicular to each other, the second side plate 160 is located at one side of the main body 140 in the third direction, and the first fixing member is penetrated through the outer wall of the main body 140 and the second side plate 160. When the second net cover 400 is connected to the main body 140, the first fixing member corresponds to the position of the second net cover 400; when the second net cover 400 is separated from the main body 140, the first fixing member is exposed.

[0082] For example, after the HVAC equipment outdoor unit 1 is installed, the first direction may be a direction perpendicular to the wall, and the outer wall may 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 an air outlet area 110 and an electrical area 120. The second direction may be a horizontal direction 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 may be a vertical direction, the second side panel 160 is installed on the upper side of the main body 140, and the first fixing member may be a threaded fastener, such as a bolt or a screw.

[0083] When the second mesh cover 400 is connected to the main body 140, the second mesh cover 400 can have a certain shielding effect on the first fixing part, so that the first fixing part is not easy to be disassembled, so as to prevent the first fixing part from being disassembled by mistake. When the HVAC equipment outdoor unit 1 needs to be repaired, in some cases, the second side plate 160 needs to be disassembled and repaired from the top of the HVAC equipment outdoor unit 1. Since the second mesh cover 400 is detachably connected to the main body 140, after the second mesh cover 400 is disassembled from the main body 140, the first fixing part can be easily disassembled, thereby ensuring the convenience of disassembly between the main body 140 and the second side plate 160, and taking into account both safety and convenience of disassembly and assembly.

[0084] like Figure 3-Figure 5 As shown, 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 .

[0085] 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.

[0086] 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 .

[0087] 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.

[0088] like Figure 7 , Figure 8 , Fig.13 and Fig.14As shown, the HVAC outdoor unit 1 further includes a decorative block 430, which is rotatably connected to the hole 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 cover the first fixing member.

[0089] 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 disassemble and assemble 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 can be covered, and the user cannot observe 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 is not easy to contact the first fixing member, which reduces the corrosion aging rate of the first fixing member due to moisture and prolongs the service life of the first fixing member. In addition, the appearance of the HVAC equipment outdoor unit 1 is neater.

[0090] like Figure 8 , Fig.13 and Fig.14 As shown, one of the decorative block 430 and the hole 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 in 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, that is, 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 larger movement range relative to the hole wall of the through hole 170. In this way, it is more in line with the force application method of the human body, and it is convenient for the staff to switch the decorative block 430 between the open position and the closed position.

[0091] like Figure 8 , Fig.13 and Fig.14 As shown, a damping protrusion 432 is provided on the outer surface of the decorative block 430 and one of the hole walls of the through hole 170. During the rotation of the decorative block 430, the outer surface of the decorative block 430 and the other of the hole walls of the through hole 170 contact to generate friction damping force.

[0092] 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 forces, and ensuring that the decorative block 430 can only rotate when the operator applies force to the decorative block 430.

[0093] like Figure 8 , Fig.13 and Fig.14 As shown, 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.

[0094] 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.

[0095] like Figure 8 , Fig.13 and Fig.14 As shown, the first damping protrusions 433 are disposed on two opposite sides of the outer surface of the decorative block 430 in the third direction. The second damping protrusions 434 are disposed on two opposite sides of the outer surface of the decorative block 430 in the third direction.

[0096] In this way, the decoration block 430 is evenly stressed on two opposite sides in the third direction, which can avoid the problem of deflection of the decoration block 430 during rotation, and ensure that the decoration block 430 rotates more smoothly.

[0097] like Fig.14 As shown, the 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.

[0098] 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 can also reduce the exertion of the staff during the entire rotation process, making the operator more labor-saving.

[0099] like Figure 7 and Figure 8 As shown, the hole wall of the through hole 170 includes a ring edge 172 .

[0100] The ring edge 172 is arranged on a 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 located in the closed position, and the damping protrusion 432 is located in the avoidance gap 173.

[0101] 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 the force, thereby extending the service life of the through hole 170 and the decorative block 430.

[0102] In some embodiments of the present invention, the avoidance gap 173 can be connected to the rotation groove 171. When the decorative block 430 rotates from the closed position to the open position, the rotation shaft 431 can move from the rotation groove 171 to the avoidance gap 173 to expand the movement range of the decorative block 430.

[0103] like Figure 5 , Figure 6 , Fig.13 and Fig.14 As shown, 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 .

[0104] 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 against 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.

[0105] like Figure 5 , Figure 6 , Fig.13 and Fig.14 As shown, 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, so 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.

[0106] 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.

[0107] like Figure 5 , Figure 6 , Fig.13 and Fig.14 As shown, the hole wall of the 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 against the limit block 175.

[0108] By setting the cooperation between the limit block 175 and the inclined surface 437, on the one hand, it is possible to prevent the decorative block 430 from excessively rotating in 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 rotating 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, thereby improving the smoothness of the rotation of the decorative block 430.

[0109] like Figure 5 , Figure 6 , Fig.13 and Fig.14 As shown, the first rib 436 is provided on the side of the decorative block 430 facing away from the housing 100. The second rib 440 and the third rib 441 are provided on the side of the second mesh cover 400 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 located 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.

[0110] For example, the first rib 436 may be one or more. If there are multiple first ribs 436, 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 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.

[0111] 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.

[0112] In addition, the first rib 436 may extend along a straight line or along a curve.

[0113] like Figure 5-Figure 8 As shown, the above-mentioned HVAC equipment outdoor unit 1 also includes a second fixing member.

[0114] 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.

[0115] For example, the second fixing member can be a threaded fastener, such as a bolt or a screw. By setting the second fixing member, the relative position between the second mesh cover 400 and the housing 100 can be fixed, and when the second mesh cover 400 is connected to the housing 100, 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 disassemble and assemble the second fixing member corresponding to the through hole 170 through the through hole 170; the decorative block 430 can cover the through hole 170 in the closed position, 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 contacted, which improves safety. On the other hand, in rainy or snowy weather, rain or snow is not easy to contact the second fixing member, which reduces the corrosion and aging rate of the second fixing member due to moisture, and prolongs the service life of the first fixing member. In addition, the appearance of the HVAC equipment outdoor unit 1 is neater.

[0116] In some embodiments of the present invention, the first fixing member may be inserted 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.

[0117] The following describes a HVAC device according to an embodiment of the present invention with reference to the accompanying drawings. The HVAC device includes the HVAC device outdoor unit 1 according to the present invention.

[0118] According to the HVAC equipment of the embodiment of the present invention, the HVAC equipment outdoor unit 1 is used, and the first side plate 150 is provided to limit the relative position between the housing 100 and the second mesh cover 400, thereby achieving the advantages of stable connection and convenient maintenance.

[0119] Other structures and operations of the HVAC equipment outdoor unit 1 and the HVAC equipment having the same according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
