[0034] In the description of the present invention, "plurality" means two or more.

[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] like Figure 1-Figure 7 As shown, the HVAC equipment outdoor unit 1 according to an embodiment of the present invention includes a housing 100 , a fan and a mesh cover 300 .

[0037] An outer wall of the housing 100 has an air outlet area 110 and an electrical area 120. The air outlet area 110 is provided with an air outlet 111. The fan is arranged in the housing 100 and is located at the air outlet 111. The mesh cover 300 is slidably arranged on the housing 100 between a first position and a second position. When the mesh cover 300 is located at 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 mesh cover 300 is located at the second position, at least a portion of the electrical area 120 blocked when the mesh cover 300 is located at the first position is staggered with the mesh cover 300 in the sliding direction of the mesh cover 300.

[0038] For example, HVAC equipment may include air conditioners, multi-split units, heat pumps, water heaters, and swimming pool units. The HVAC equipment may realize at least one of the functions of heating, ventilation, and air conditioning.

[0039] According to the HVAC equipment outdoor unit 1 of the embodiment of the present invention, the housing 100 may include 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 top walls, bottom walls and side walls cooperate to form an installation cavity, and the fan is arranged in the installation cavity of the housing 100. In practical applications, the bottom wall of the HVAC equipment outdoor unit 1 is usually placed on the installation surface, and an air outlet area 110 and an electrical area 120 are arranged on an outer wall of the housing 100. The above outer wall of the housing 100 may correspond to the side wall or the top side, and there is no limitation on this. 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 HVAC equipment outdoor unit 1, and the fan then guides the gas after heat exchange to be discharged from the housing 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 a compressor and other electrical components, for performing maintenance operations on the outdoor unit 1 of the HVAC equipment.

[0040] In addition, the mesh cover 300 is slidably disposed on the housing 100, and the mesh cover 300 slides between a first position and a second position. When the mesh cover 300 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 mesh cover 300 is in the second position, at least a portion of the area of ​​the electrical area 120 that is blocked when the mesh cover 300 is in the first position is offset from the mesh cover 300 in the sliding direction of the mesh cover 300.

[0041] It should be noted that when the mesh cover 300 is in the first position, the air outlet area 110 and the electrical area 120 are shielded, which means that when the mesh cover 300 is in the first position, at least a portion of the orthographic projection of the air outlet area 110 on the plane where the mesh cover 300 is located and at least a portion of the orthographic projection of the electrical area 120 on the plane where the mesh cover 300 is located are located in the area surrounded by the outline of the mesh cover 300, wherein the orthographic projection of the air outlet 111 on the plane where the mesh cover 300 is located is located in the area surrounded by the outline of the mesh cover 300, 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 mesh cover 300 are located may be located in the area surrounded by the outline of the mesh cover 300. When the mesh cover 300 is in the second position, at least a portion of the area blocked by the electrical zone 120 at the first position of the mesh cover 300 is offset from the mesh cover 300 in the sliding direction of the mesh cover 300, which means that when the mesh cover 300 is in the second position, at least a portion of the area blocked by the electrical zone 120 at the first position of the mesh cover 300 is blocked, 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 mesh cover 300 is located is outside the area surrounded by the outline of the mesh cover 300. The operator can operate the area of ​​the electrical zone 120 that is not blocked by the mesh cover 300 to repair the outdoor unit 1 of the HVAC equipment.

[0042] When the mesh cover 300 is in the first position, it blocks at least a part of the air outlet area 110 and at least a part of the electrical area 120. At this time, external objects or personnel can be blocked by the mesh cover 300 and will not touch the air outlet area 110 and the electrical area 120, or can touch a smaller area of ​​the air outlet area 110 and a smaller area of ​​the electrical area 102. On the one hand, it is not easy for external objects, clothing of personnel, and body parts such as hands to touch the fan through the air outlet 111, so as to avoid damage caused by collision when the fan rotates, and also avoid scratches of personnel when the fan rotates. On the other hand, external objects and personnel will not touch the electrical area 120, so as to ensure the normal operation of the electrical components in the electrical area 120, reduce the probability of damage to the electrical components in the electrical area 120, and prevent injuries to personnel.

[0043] When the mesh cover 300 is in the second position, at least a portion of the blocked area of ​​the electrical zone 120 at the first position of the mesh cover 300 is offset from the mesh cover 300 in the sliding direction of the mesh cover 300. At this time, at least a portion of the blocked area of ​​the electrical zone 120 at the first position of the mesh cover 300 is not blocked by the mesh cover 300. 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 detection on the outdoor unit 1 of the HVAC equipment.

[0044] It should be noted that the electrical area 120 may be additionally provided with a cover plate or other structures. When the mesh cover 300 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 can be operated to further improve safety. Alternatively, the controller 120 may not be additionally provided with a cover plate. When the mesh cover 300 is in the second position, the electrical components in the electrical area 120 can be directly operated, which reduces the operating steps and improves the convenience of operation.

[0045] Thus, 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 and improve safety by switching the position of the mesh cover 300 , but also facilitate the operation of electrical components in the electrical area 120 .

[0046] According to some specific embodiments of the present invention, Figure 2 As shown, when the mesh cover 300 is in the second position, it blocks at least a portion of the air outlet 111. When the mesh cover 300 is in the second position, the orthographic projection of most or all areas of the air outlet 111 on the plane where the mesh cover 300 is located is located within the area surrounded by the outline of the mesh cover 300, that is, when the mesh cover 300 is in the second position, it still blocks most or all areas of the air outlet 111.

[0047] When the electrical components in the electrical area 120 are in operation, the fan may also be rotating. Therefore, the mesh cover 300 still covers most or all of the air outlet 111, and external objects or personnel can be blocked by the mesh cover 300 and are not easy to contact 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 it rotates, and also avoids the staff being scratched when the fan rotates.

[0048] According to some specific embodiments of the present invention, Figure 4 and Figure 6As shown, the outer wall of the housing 100 is provided with a first stopper, and the side of the mesh cover 300 facing the housing 100 is provided with a second stopper, and the first stopper cooperates with the second stopper to limit the sliding stroke of the mesh cover 300. Through the cooperation of the first stopper and the second stopper, the mesh cover 300 is prevented from being separated from the housing 100 in its sliding direction, and the housing 100 and the mesh cover 300 are prevented from being separated, and the operator does not need to control his own force and force application time, thereby improving the convenience of use.

[0049] According to some specific embodiments of the present invention, Figure 4 and Figure 6 As shown, the first limiting member includes a first limiting protrusion 130 and a second limiting protrusion 140, and the second limiting member is a third limiting protrusion 320. The third limiting protrusion 320 can be located between the first limiting protrusion 130 and the second limiting protrusion 140 in the sliding direction of the mesh cover 300; wherein, when the mesh cover 300 is located in the first position, the third limiting protrusion 320 stops at the first limiting protrusion 130; and when the mesh cover 300 is located in the second position, the third limiting protrusion 320 stops at the second limiting protrusion 140.

[0050] That is to say, during the sliding process of the mesh cover 300, if the third limiting protrusion 320 stops at the first limiting protrusion 130, the mesh cover 300 is in the first position, and the third limiting protrusion 320 and the second limiting protrusion 140 are spaced apart; if the third limiting protrusion 320 stops at the second limiting protrusion 140, the mesh cover 300 is in the second position, and the third limiting protrusion 320 and the first limiting protrusion 130 are spaced apart.

[0051] Through the mutual cooperation between the first limiting protrusion 130, the second limiting protrusion 140 and the third limiting protrusion 320, it is possible to prevent the mesh cover 300 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 mesh cover 300.

[0052] Specifically, the first limiting protrusion 130 can be located on the side of the electrical area 120 facing away from the air outlet area 110, which can ensure that the electrical area 120 can be shielded by the mesh cover 300 to a greater extent when the mesh cover 300 is in the first position. The third limiting protrusion 320 is located on the side of the mesh cover 300 facing the first limiting protrusion 130, so as to maximize the use of the area of ​​the mesh cover 300 and save costs. The second limiting protrusion 140 can be located at the junction between the air outlet area 110 and the electrical area 120, which can ensure that the electrical area 120 can be shielded by the mesh cover 300 to a greater extent when the mesh cover 300 is in the second position, which is conducive to operating the electrical components in the electrical area 120.

[0053] According to some specific embodiments of the present invention, Figure 4 and Figure 6 As shown, the first limiting protrusion 130 is provided with a first fixing hole 131, and the first fixing member passing through the first fixing hole 131 is detachably connected to the third limiting protrusion 320 when the mesh cover 300 is located at the first position. The first fixing member may be a threaded fastener, such as a bolt or a screw, and the third limiting protrusion 320 may be provided with a threaded hole. The first fixing member passes through the first fixing hole 131 and is threadedly connected to the threaded hole of the third limiting protrusion 320, or the first fixing member passes through the first fixing hole 131 and can be clamped with the third limiting protrusion 320.

[0054] By setting the first fixing member, the mesh cover 300 can be fixed in the first position, preventing the mesh cover 300 from sliding relative to the shell 100 without human operation, thereby ensuring the positioning reliability between the mesh cover 300 and the shell 100, which is beneficial to reducing the probability of accidental exposure of the electrical area 120 and preventing the mesh cover 300 from being damaged by collision during the handling and transportation of the HVAC equipment outdoor unit 1.

[0055] According to some specific embodiments of the present invention, Figure 4 and Figure 6 As shown, the outer wall of the housing 100 is provided with a first fixing protrusion 150, the first fixing protrusion 150 and the first limiting protrusion 130 are located at opposite sides of the housing 100 in the sliding direction of the mesh cover 300, a second fixing protrusion 330 is provided on the side of the mesh cover 300 facing the housing 100, and the second fixing protrusion 330 is located on the side of the first fixing protrusion 150 facing away from the first limiting protrusion 130. The second fixing protrusion 330 is provided with a second fixing hole 331, and when the mesh cover 300 is located in the first position, the second fixing member passing through the second fixing hole 331 is detachably connected to the first fixing protrusion 150.

[0056] For example, the second fixing member may be a threaded fastener, such as a bolt or a screw, etc., the first fixing protrusion 150 may be provided with a threaded hole, and the second fixing member may be threadedly connected with the threaded hole of the first fixing protrusion 150 after passing through the second fixing hole 331, or the second fixing member may be clamped with the first fixing protrusion 150 after passing through the second fixing hole 331. In addition, the second fixing protrusion 330 and the third limiting protrusion 320 may be integrally formed with the mesh cover 300, and the size of the second fixing protrusion 330 in the axial direction of the air outlet 111 and the size of the third limiting protrusion 320 in the axial direction of the air outlet 111 may be the same.

[0057] By setting the cooperation between the first fixing protrusion 150 and the second fixing protrusion 330, the net cover 300 can be fixed in the first position more reliably, and the net cover 300 can be more effectively prevented from sliding relative to the housing 100 in the case of non-human operation. In addition, the first fixing protrusion 150 and the first limiting protrusion 130 are located on opposite sides of the housing 100 in the sliding direction of the net cover 300, and the net cover 300 is more evenly stressed as a whole when in the first position. In addition, the second fixing protrusion 330 is located on the side of the first fixing protrusion 150 that is away from the first limiting protrusion 130. When the net cover 300 slides from the first position to the second position, the first fixing protrusion 150 will not interfere with the second fixing protrusion 300, and the movement of the net cover 300 is smooth.

[0058] According to some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the sliding direction of the mesh cover 300 , 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 mesh cover 300 .

[0059] It should be noted that the direction indicated by arrow A in the accompanying drawings is the sliding direction of the mesh cover 300 , the direction indicated by arrow B is the height direction of the HVAC equipment outdoor unit 1 , and the direction indicated by arrow C is the axial direction of the air outlet 111 .

[0060] 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 mesh cover 300 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.

[0061] In this way, the sliding direction of the mesh cover 300 is more consistent with the force habit of human hands, thereby making it easier for operators to push and pull the mesh cover 300.

[0062] According to some specific embodiments of the present invention, Figure 4-Figure 7 As shown, the outer wall of the shell 100 is provided with a first limiting structure 160, and the mesh cover 300 is provided with a second limiting structure 310. The first limiting structure 160 and the second limiting structure 310 are slidably matched with each other to limit the relative position of the mesh cover 300 and the shell 100.

[0063] For example, the first limiting structure 160 and the second limiting structure 310 are located above or below the air outlet area 110 and the electrical area 120, or the first limiting structure 160 and the second limiting structure 310 are disposed above and below.

[0064] By setting the cooperation of the first limiting structure 160 and the second limiting structure 310, not only can the relative sliding of the mesh cover 300 and the shell 100 in a preset direction be limited, but also the relative position between the mesh cover 300 and the shell 100 can be limited. The mesh cover 300 is not easy to separate from the shell 100, thereby improving the convenience of operation.

[0065] It should be noted that the first limiting structure 160 can be located above the air outlet area 110 and the electrical area 120. Under the action of gravity, the mesh cover 300 can naturally droop so that the first limiting structure 160 and the second limiting structure 310 can be reliably matched, and the mesh cover 300 is not easy to flip downward relative to the shell 100, which can ensure that the mesh cover 300 is stably fixed to the shell 100.

[0066] According to some specific embodiments of the present invention, Figure 4-Figure 7 As shown, the first limiting structure 160 includes a first connecting section 161 , a bending section 162 and a first limiting section 163 .

[0067] The first connecting section 161 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 162 is connected to the upper side of the first connecting section 161 and extends in the direction away from the shell 100, and the first limiting section 163 is connected to a side of the bending section 162 away from the shell 100 and extends upward, wherein at least a portion of the second limiting structure 310 is located between the first limiting section 163 and the shell 100 in the axial direction of the air outlet 111.

[0068] For example, the first connecting section 161, the bending section 162 and the first limiting section 163 may be integrally formed. Furthermore, the first connecting section 161 and the housing 100 may be connected by a threaded fastener, and the first connecting section 161 may be attached to the housing 100 to increase the contact area between the housing 100 and the first limiting structure 160, thereby ensuring the connection strength between the housing 100 and the first limiting structure 160.

[0069] At least a portion of the second limiting structure 310 is placed between the first limiting section 163 and the shell 100. In this way, when the mesh cover 300 and the shell 100 move away from each other in the axial direction of the air outlet 111, the second limiting structure 310 and the first limiting section 163 will abut against each other, thereby limiting the relative position between the mesh cover 300 and the shell 100 in the axial direction of the air outlet 111 and preventing the mesh cover 300 from falling off the shell 100.

[0070] According to some specific embodiments of the present invention, Figure 3 and Figure 5 As shown, the second limiting structure 310 includes a second connecting section 311 and a second limiting section 312 .

[0071] One side of the second connecting section 311 is connected to the side of the mesh cover 300 facing the shell 100, and the second limiting section 312 is connected to the side of the second connecting section 311 facing the shell 100 and extends downward. The second limiting section 312 is located between the first limiting section 163 and the shell 100 in the axial direction of the air outlet 111.

[0072] Among them, the second limiting structure 310 can be integrally formed with the mesh cover 300, and the second connecting section 311 can be supported on the upper side of the first limiting section 163, or the second limiting section 312 is supported on the bending section 162 to limit the relative position of the mesh cover 300 and the shell 100 in the height direction of the HVAC equipment outdoor unit 1.

[0073] In this way, through the mutual cooperation between the first limiting section 163 and the second limiting section 312, when the mesh cover 300 moves away from each other along the axial direction of the air outlet 111, the relative position between the mesh cover 300 and the shell 100 in the axial direction of the air outlet 111 can be limited, thereby preventing the mesh cover 300 from falling off the shell 100.

[0074] In addition, when the net cover 300 is moved upward relative to the housing 100, the second limiting section 312 can be higher than the first limiting section 163, and the net cover 300 can be removed from the housing 100 to clean, repair or replace the net cover 300. When the net cover 300 is moved downward relative to the housing 100, the second limiting section 312 is inserted between the first limiting section 163 and the housing 100, and the net cover 300 can be fixed to the housing 100.

[0075] According to some specific embodiments of the present invention, Figure 3 As shown, the first limiting structure 160 further includes a support section 164, which is connected to the upper side of the first limiting section 163 and extends in a direction away from the housing 100, and the support section 164 is supported on the lower surface of the second limiting section 312. The second limiting section 312 is provided with a third fixing hole 313, and the third fixing member passing through the third fixing hole 313 is connected to the support section 164.

[0076] For example, the third fixing member can be a threaded fastener, such as a bolt or a screw, and the support section 164 can be provided with a threaded hole. The third fixing member passes through the third fixing hole 313 and is threadedly connected to the threaded hole of the support section 164, or the third fixing member passes through the third fixing hole 313 and can be clamped with the support section 164.

[0077] By setting the support section 164, on the one hand, the contact area between the first limiting structure 160 and the mesh cover 300 can be increased to improve the limiting effect. On the other hand, the relative position between the support section 164 and the second limiting section 312 can be fixed by the third fixing member, thereby achieving the fixation of the relative position between the shell 100 and the mesh cover 300.

[0078] In addition, the third limiting protrusion 320 is lower than the support section 164 in the height direction of the HVAC equipment outdoor unit 1, so as to avoid mutual interference between the third limiting protrusion 320 and the support section 164 when the mesh cover 300 slides. The highest point of the second fixing protrusion 330 in the height direction of the HVAC equipment outdoor unit 1 can be higher than the lowest point of the support section 164. When the mesh cover 300 is in the first position, the second fixing protrusion 330 can stop at the support section 164 to form a limiting effect.

[0079] According to some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, at least one of the lower side of the support section 164 and the side of the first limiting section 163 facing the mesh cover 300 is provided with a second limiting protrusion 140, and the side of the mesh cover 300 facing the housing 100 is provided with a third limiting protrusion 320. When the mesh cover 300 is in the second position, the third limiting protrusion 320 stops at the second limiting protrusion 140; when the mesh cover 300 is in the first position, the third limiting protrusion 320 is spaced from the second limiting protrusion 140.

[0080] That is to say, the second limiting protrusion 140 is arranged on the side of the first limiting section 163 facing the mesh cover 300, or the second limiting protrusion 140 is arranged on the lower side of the supporting section 164, or the second limiting protrusion 140 is arranged on both the side of the first limiting section 163 facing the mesh cover 300 and the lower side of the supporting section 164.

[0081] Through the cooperation between the second limiting protrusion 140 and the third limiting protrusion 320, when the mesh cover 300 slides, the mesh cover 300 can be limited to the second position and will not be separated from the shell 100. The second limiting protrusion 140 and the first limiting structure 160 can be formed in one piece, which is beneficial to reduce the processing difficulty and improve the structural strength. Compared with the air outlet area 110 and the electrical area 120, the support section 164 and the first limiting section 163 are closer to the mesh cover 300. Therefore, the second limiting protrusion 140 is set on at least one of the support section 164 and the first limiting section 163. The axial size of the second limiting protrusion 140 in the air outlet 111 can be reduced, thereby reducing the cost. In addition, during the transportation, production and handling of the shell 100, the second limiting protrusion 140 is less likely to interfere with other objects.

[0082] In some specific embodiments of the present invention, Figure 5 and Figure 6As shown, the third limiting protrusion 320 can be provided with a plurality of first weight reducing holes 321 arranged at intervals along the height direction of the HVAC equipment outdoor unit 1, the second fixing protrusion 330 can be provided with a plurality of second weight reducing holes 332 arranged at intervals along the height direction of the HVAC equipment outdoor unit 1, and the second connecting section 311 can be provided with a plurality of third weight reducing holes 314 arranged at intervals along the sliding direction of the mesh cover 300.
