Description

Technical Field

[0001] The present invention relates to the technical field of air outlet structures, and in particular to an air outlet device for an air conditioner and air conditioning equipment. Background Art

[0002] The air outlet structure refers to the part of the air conditioning system such as air conditioners and ventilation equipment that is used to guide, regulate, and control the flow of air. It is responsible for delivering air that has been cooled, filtered, and other steps to the room or specific environment to ensure the effective distribution and control of the airflow. Different from air conditioners used in home scenarios, air conditioners used in data centers, computer rooms, and other scenarios have higher redundancy requirements. Once an air conditioner stops operating unexpectedly or requires regular maintenance, if there is no other air conditioner to take over, the electronic equipment in the data center and computer room needs to be shut down to prevent the electronic equipment from overheating; therefore, in the above scenarios, in order to ensure the redundancy of the system operation, multiple groups of air conditioners are generally set up, such as one group of air conditioners operating normally and the other group of air conditioners for emergency use, such as setting two groups of air conditioners to operate alternately, and regularly maintaining the shut-down air conditioning equipment.

[0003] Generally speaking, when an air conditioner changes from a working state to a shutdown state, the fan in its air outlet structure stops working first. When the fan stops working completely, the grille plate of the air outlet structure is closed to separate the air conditioner from the environment. But in fact, in scenarios such as data centers and computer rooms, when one air conditioner enters a shutdown state, another air conditioner is often already in working state. In this case, indoor dust enters the air conditioner before the grille plate of one air conditioner is completely closed, and then accumulates dust in the air conditioner. Over time, when multiple groups of air conditioners work alternately, dust is easily accumulated inside the air conditioner and in the air outlet structure, affecting the stability of the air conditioner. In addition, if the grille plate is closed first and then the fan is stopped, or if the grille plate and the fan are closed at the same time, positive pressure is easily generated in the air duct of the air conditioner due to the inertia of the fan itself. Over time, the air duct is easily deformed, affecting the air outlet effect of the air conditioner and resulting in a decrease in the working life of the air conditioner.

[0004] In summary, the air outlet structure in the prior art is difficult to solve the technical problem of dust accumulation inside when multiple groups of air conditioners work alternately while maintaining the working life of the air conditioners. Summary of the invention

[0005] The purpose of the present invention is to provide an air outlet device and air conditioning equipment for an air conditioner, so as to solve the technical problem in the prior art that it is difficult to solve the problem of dust accumulation inside the air outlet structure when multiple groups of air conditioners work alternately while maintaining the working life of the air conditioner.

[0015] The rotation axis of the air guide member is located above the air guide member, and the air guide member at least partially protrudes from the air guide top shell along the air inlet direction;

[0016] The air guide portion is also correspondingly provided with a locking assembly, and the locking assembly is used to lock the position of the air guide member when the air guide member deviates from the air inlet direction and does not block the trigger portion.

[0017] Optionally, the locking assembly comprises a locking column mounted on the air guide, an arc-shaped slide groove portion concentric with the rotation axis, a clamping slide groove portion communicating with a terminal end of the arc-shaped slide groove portion, and an elastic portion mounted on the air guide;

[0018] The extending direction of the engaging slot portion does not coincide with the extending direction of the arcuate slot portion, and the elastic portion is used to apply elastic force to the locking column so that the locking column has a tendency to move toward the engaging slot portion.

[0019] Optionally, the engaging slide groove portion is extended from the end of the arc-shaped slide groove portion in a direction close to the air outlet plate;

[0020] In the gap between the air guide and the top shell support portion, a reset collar is fixedly connected to the locking column, and a reset plate is extended from the reset collar;

[0021] Among them, when the air guide member does not deviate from the air inlet direction, the reset plate does not protrude from the air guide top shell; when the air guide member deviates from the air inlet direction, the reset plate at least partially protrudes from the air guide top shell, and the length of the protruding part of the reset plate is greater than the length of the engaging slide groove portion.

[0022] Optionally, the rotating assembly includes a rotating shaft member penetrating the air guide top shell, the rotating shaft member is rotatably connected to an extension member, and an end of the extension member away from the rotating shaft member is fixedly connected to the air guide member;

That is to say, for the air-conditioning outlet device, in the process of shutting down, until the air guide channel is pushed away by the trigger part, the airflow brought by the inertia of the fan can still be discharged through the air guide channel and the air outlet channel, thereby preventing dust accumulation inside; and, through the setting of the buffer space, the space connected to the air inlet channel inside will gradually increase, which means that when the air outlet channel is completely closed, the excess wind brought by the inertia of the fan can be cached through the buffer space, reducing the direct impact on the air duct, and compared with directly closing the air outlet channel, the internal air pressure increases less, thereby ensuring the working life of the air-conditioning outlet device. Therefore, the air outlet device and air conditioning equipment of the air conditioner can solve the problem of easy internal dust accumulation when multiple sets of air conditioners work alternately, while being able to ensure the life of the air duct.

[0045] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0047] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods. Embodiment 1:

[0048] The air-conditioning outlet device provided by the present invention is suitable for scenarios where multiple air-conditioners are linked together. For example, multiple redundant air-conditioners are arranged in a computer room and are divided into at least two batches, one batch is working and the other batch is shut down for maintenance by operation and maintenance personnel. In this embodiment, by improving the structure of the air-conditioning outlet device so that it can operate alternately, especially in a scenario where one air-conditioning outlet device is running and the other air-conditioning outlet device needs to be shut down, the accumulation of dust inside the air-conditioning outlet device can be reduced, and at the same time, the situation in which the life of the air duct cannot be guaranteed can be avoided.

[0049] like Figure 1 and Figure 2As shown, the air outlet device of the air conditioner in this embodiment includes a housing 100 provided with an air inlet channel 001, an air guide portion 200 provided with an air guide channel 002 (i.e., an air duct), and an air outlet plate 300 provided with an air outlet channel 003. The air inlet channel 001, the air guide channel 002, and the air outlet channel 003 are sequentially connected along the air inlet direction; this means that the cooling device in the air conditioner can input cold air into the air inlet channel 001, and the cold air is discharged from the air outlet channel 003 through the air inlet channel 001 and the air guide channel 002; wherein the cooling device refers to a device capable of cooling the air. The cooling device, including but not limited to a condenser, a cooling water tower, etc., can cool the air and is not specifically limited in this embodiment; wherein, the air inlet channel 001 can be provided with a centrifugal fan, an axial flow fan and other structures to guide and accelerate the cold air; the air guide channel 002 plays a role in guiding the cold air, and can guide and disperse the flow of cold air, thereby improving the air supply efficiency of the air conditioner, which is well known to those skilled in the art, and includes but is not limited to tubular air guide ducts, air guide holes and other forms, which are not specifically limited in this embodiment and can guide the airflow.

[0050] like Figures 1 to 4 As shown, the air outlet plate 300 is slidably connected to the blocking plate 400 in the vertical direction. The blocking plate 400 can slide between an initial position and a sealing position that blocks the air outlet channel 003. The initial position refers to a position where the blocking plate 400 and the air outlet channel 003 do not overlap, and the sealing position refers to a position where the blocking plate 400 completely blocks all the air outlet channels 003. Figure 5 As shown, the air guide portion 200 is rotatably connected to the shell 100 so that the air guide channel 002 can deviate from the air inlet direction; buffer spaces 004 with a larger volume than the air guide channel 002 are arranged on both sides of the air guide portion 200 in the vertical direction, and when the air guide channel 002 is arranged along the air inlet direction, the buffer space 004 and the air inlet channel 001 are separated by the air guide channel 002; it can be understood that when the air guide channel 002 of the air guide portion 200 is arranged along the air inlet direction, most of the cold air can directly enter the air guide channel 002 and finally be discharged through the air outlet plate 300; when the air guide channel 002 of the air guide portion 200 is arranged deviating from the air inlet direction, it is difficult for the cold air to directly enter the air guide channel 002, but directly enters the buffer space 004, and when the blocking plate 400 is closed and cold air is still continuously provided, the direct impact on the air guide channel 002 is reduced.

[0051] A trigger portion 410 is provided on the end of the blocking plate 400 close to the air outlet channel 003. When the blocking plate 400 moves to the sealing position, the air guide portion 200 is pushed by the trigger portion 410 in a direction deviating from the air inlet direction, so that the air guide portion 200 can deviate from the air inlet direction when the blocking plate 400 is closed.

[0052] Illustratively, the air-conditioning outlet device in this embodiment, when the air-conditioning outlet device needs to be shut down, turns off the fan of the air-conditioning outlet device, and in the process of the fan stopping rotation, the blocking plate 400 is moved from the initial position to the sealing position to gradually block the air outlet channel 003; at the same time, as the end of the blocking plate 400 moves toward the sealing position, it will drive the trigger part 410 to push the air guide part 200, so that the air guide channel 002 deviates from the air inlet direction, so that the air guide channel 002 and the air outlet channel 003 are staggered, and the buffer space 004 is connected with the air inlet channel 001. That is to say, for the air-conditioning outlet device, during the shutdown process, until the air-guiding channel 002 is pushed away by the trigger unit 410, the airflow caused by the inertia of the fan can still be discharged through the air-guiding channel 002 and the air-outlet channel 003, thereby preventing dust accumulation inside; and, through the setting of the buffer space 004, the internal space connected to the air-inlet channel 001 will gradually increase, which means that when the air-outlet channel 003 is completely closed, the surplus air caused by the inertia of the fan can be buffered through the buffer space 004, reducing the direct impact on the air duct. Compared with directly closing the air-outlet channel 003, the internal air pressure increases less, thereby ensuring the working life of the air-conditioning outlet device. Therefore, the present air-conditioning outlet device solves the problem of easy internal dust accumulation when multiple groups of air conditioners work alternately, while being able to ensure the life of the air duct.

[0053] In a specific embodiment, Figure 3 and Figure 4 As shown, the number of the air guide parts 200 is multiple, and they are arranged in sequence at intervals along the vertical direction; Figure 5 As shown, the air guide portion 200 includes an air guide shell portion 210 configured with an air guide cavity 005 and an air guide member 220 configured with an air guide channel 002; along the air inlet direction, the air guide shell portion 210 is provided with a avoidance opening 006 to connect the air inlet channel 001 with the air guide channel 002; wherein, the air guide cavity 005 is separated by the air guide portion 200 that does not deviate from the air inlet direction to form two buffer spaces 004.

[0054] It can be understood that the shell 100 forms a cavity, in which a plurality of air guides 200 are arranged along the vertical direction, an air inlet is provided on one wall of the cavity, and an air outlet is formed on the other wall of the cavity by installing an air outlet plate 300; at this time, the air guide 200 divides the entire cavity, so that an air inlet channel 001 is formed between the air guide 200 and the air inlet, and an air outlet channel 003 is formed between the air guide 200 and the air outlet. On this basis, the air guide shell 210 can be a sheet metal structure installed in the shell 100, which forms an air guide inner cavity 005 in the above-mentioned cavity, and the air guide member 220 is rotatably connected to the air guide inner cavity 005. When the air guide channel 002 of the air guide member 220 is set along the air inlet direction, most of the cold air can directly enter the air guide channel 002 through the avoidance port 006, and finally be discharged through the air outlet plate 300; when the air guide channel 002 of the air guide member 220 is set away from the air inlet direction, it means that the air guide channel 002 and the avoidance port 006 are staggered. At this time, it is difficult for cold air to directly enter the air guide channel 002, but enters the buffer space 004 through the avoidance port 006. When the blocking plate 400 is closed and cold air is still continuously provided, the direct impact on the air guide channel 002 is reduced.

[0055] As another optional implementation, the number of the air guide portion 200 may be one.

[0056] In a specific embodiment, Figures 1 to 5 As shown, the initial position is located above the sealing position; the air guide shell 210 of the air guide portion 200 includes an air guide top shell 211 and a top shell support portion 212 supporting the air guide top shell 211, and the air guide portion 200 also includes an air guide member 220 configured with an air guide channel 002, and the air guide member 220 is rotatably connected to the air guide top shell 211 through a rotating assembly 230. The rotation axis of the air guide member 220 is located above the air guide member 220, and the air guide member 220 at least partially protrudes from the air guide top shell 211 along the air inlet direction; the air guide portion 200 is also correspondingly provided with a locking assembly 500, which is used to lock the position of the air guide member 220 when the air guide member 220 deviates from the air inlet direction and does not block the trigger portion 410.

[0057] It is understandable that the initial position is located above the sealing position, which means that the trigger part 410 moves from top to bottom. In this way, the rotation axis is located above the air guide 220, which means that the air guide 220 rotates inward. Then, after the trigger part 410 moves downward for a certain distance, it will separate from the air guide 220. At this time, the locking assembly 500 is in the position of locking the air guide 220. As other supplementary embodiments, the initial position can be located below the sealing position. Correspondingly, the rotation axis of the air guide 220 is located below the air guide 220, which can also achieve the separation of the trigger part 410 and the air guide 220.

[0058] For example, as a preferred implementation in this embodiment, there are multiple air guides 200, which are arranged in sequence from top to bottom in the vertical direction, with the initial position located above the sealing position, and the rotation axis located above the air guide 220. In the process of the blocking plate 400 moving to the sealing position, each air outlet channel 003 is gradually closed, which means that the air outlet area is reduced, and in the process of closing an air outlet channel 003, the corresponding air guide 220 will be gradually driven to descend, and the final air outlet process of the air guide 220 can be compared to a downward spraying action, thereby effectively reducing the entry of dust.

[0059] Furthermore, if Figures 5 to 7 , Fig.10 As shown, the locking assembly 500 includes a locking column 510 installed on the air guide member 220, an arc-shaped slide groove portion 530 concentric with the rotation axis, a locking slide groove portion 540 connected to the end of the arc-shaped slide groove portion 530, and an elastic portion 520 installed on the air guide member 220; wherein, the extension direction of the locking slide groove portion 540 does not coincide with the extension direction of the arc-shaped slide groove portion 530, and the elastic portion 520 is used to apply elastic force to the locking column 510, so that the locking column 510 has a movement tendency to move toward the direction close to the locking slide groove portion 540.

[0060] In this embodiment, the engaging groove portion 540 is extended from the end of the arc-shaped groove portion 530 in a direction close to the air outlet plate 300; in the gap between the air guide member 220 and the top shell support portion 212, a reset ring 550 is fixedly connected to the outside of the locking column 510, and a reset plate 560 is extended from the reset ring 550; wherein, when the air guide member 220 does not deviate from the air inlet direction, the reset plate 560 does not protrude from the air guide top shell 211; when the air guide member 220 deviates from the air inlet direction, the reset plate 560 at least partially protrudes from the air guide top shell 211, and the length of the protruding portion of the reset plate 560 is greater than the length of the engaging groove portion 540, and there is a gap between the engaging groove portion 540 and the locking column 510.

[0061] Illustratively, when the trigger portion 410 moves from top to bottom, it avoids the air guide top shell 211 and then abuts against the air guide piece 220; after the trigger portion 410 presses the air guide piece 220 and deflects downward by a certain distance, the air guide piece 220 deflects inward, so that the trigger portion 410 can avoid the air guide piece 220 and continue to move downward. At the same time, when the locking column 510 moves to the end of the arc-shaped slide groove portion 530, under the action of the elastic portion 520, the locking column 510 is pulled into the engaging slide groove portion 540. Since the extension direction of the engaging slide groove portion 540 does not coincide with the extension direction of the arc-shaped slide groove portion 530, the locking column 510 and the engaging slide groove portion 540 are relatively fixed, thereby locking the air guide piece 220. Then, when there are multiple air guide parts 200, in the process of the blocking plate 400 moving from top to bottom, the position of each air guide member 220 can be changed in turn to deviate from the air inlet direction, thereby ensuring the life of each air guide channel 002 and having the advantage of a compact structure.

[0062] In addition, when the trigger portion 410 moves from bottom to top to return to the initial position, since the reset plate 560 at least partially protrudes from the air guide top shell 211, and the length of the protruding portion of the reset plate 560 is greater than the length of the engaging slide groove portion 540, the trigger portion 410 can push the reset plate 560 to make the locking column 510 return to the end of the arc-shaped slide groove portion 530. At this time, in conjunction with other reset forces, the air guide member 220 can be reset synchronously with the locking column 510.

[0063] As a specific embodiment, the elastic part 520 includes a limit shell 521 and a movable block 522. The limit shell 521 is provided with a movable groove, and the movable block 522 is slidably connected to the movable groove. A tension spring is installed in the movable groove, one end of the tension spring is connected to the bottom wall of the movable groove, and the other end is connected to the movable block 522. The end of the locking column 510 is installed on the movable block 522. The rotating assembly 230 includes a rotating shaft 231 that passes through the air guide top shell 211. The rotating shaft 231 is rotatably connected to an extension 232, and the end of the extension 232 away from the rotating shaft 231 is fixedly connected to the air guide 220; a torsion spring is sleeved on the rotating shaft 231, one end of the torsion spring is fixedly connected to the air guide top shell 211, and the other end of the torsion spring is fixedly connected to the extension 232, so that the air guide 220 has a movement tendency set along the air inlet direction. As another optional embodiment, a counterweight can be set at one end of the air guide 220 close to the air inlet channel 001 to replace the torsion spring.

[0064] Exemplarily, when the trigger portion 410 moves from top to bottom, after the trigger portion 410 overcomes the force of the torsion spring or the counterweight and presses the air guide member 220 to deflect downward by a certain distance, the tension spring pulls the movable block 522 and the locking column 510, so that the locking column 510 enters the engaging slide groove portion 540. At this time, the limiting relationship between the locking column 510 and the engaging slide groove portion 540 can prevent the torsion spring or the counterweight from causing the air guide member 220 to reset; then, due to the gap between the engaging slide groove portion 540 and the locking column 510, the trigger portion 410 can continue to move downward, so that the air guide member 220 deflects downward by a smaller distance and then leaves the air guide member 200, enters the downward moving air guide portion 200 or reaches the sealing position, and the locking column 510 continues to contact the upper groove wall of the engaging slide groove portion 540.

[0065] As an optional implementation, Fig.10 As shown, a piezoelectric film 600 is respectively embedded at the upper and lower ends of the air guide 220, and the piezoelectric film 600 extends to the inner wall of the air guide channel 002. The piezoelectric film 600 is electrically connected to a circuit switch structure such as a limit switch and an electromagnet switch, and the circuit switch structure can be turned on by the trigger part 410. Therefore, when the trigger part 410 presses the air guide 220 downward, the circuit switch structure can be turned on, so that the piezoelectric film 600 is powered, and the piezoelectric film 600 is subjected to voltage, so that it is squeezed inward, so that the volume of the air guide channel 002 is reduced, thereby generating airflow to be discharged from the air guide channel 002, thereby further preventing dust from entering the interior in reverse.

[0066] Based on the above implementation, Figures 7 to 9 As shown, the air guide portion 200 includes a wind shield plate 213 arranged near the air inlet channel 001 and an air guide member 220 configured for the air guide channel 002. When the air guide member 220 deviates from the air inlet direction, the entrance of the air guide channel 002 is blocked by the wind shield plate 213. In the process of the blocking plate 400 moving from top to bottom, the wind shield plate 213 can effectively reduce the residual cold air entering the air guide channel 002.

[0067] Specifically, the inner wall of the air guide member 220 is arranged in an arc shape, and the extension path of the inner wall of the air guide member 220 matches the rotation path of the lower end of the entrance of the air guide channel 002, thereby further improving the protection of the air guide channel 002, and having the advantage of a compact structure.

[0068] Based on the above implementation, Figure 4 As shown, a plurality of air outlets 301 are provided on the air outlet plate 300 corresponding to an air guide channel 002 and are arranged at intervals along the horizontal direction. The air outlet plate 300 is also provided with a trigger port 302 extending along the vertical direction.

[0069] Based on the above implementation, Figure 4 As shown, Figure 2As shown, the upper part of the cavity of the housing 100 is separated by a partition to form a lifting space 007, and a lifting device 700 is arranged in the lifting space 007. The lifting device 700 can be a synchronous belt structure equipped with a motor, and cooperates with guide rails, sliders and other structures to control the height of the blocking plate 400. As other optional embodiments, the lifting device 700 includes but is not limited to other structures with lifting functions such as gear racks and lifting cylinders. Embodiment 2:
