Description

Technical Field

[0001] The invention belongs to the technical field of air outlet of air conditioners, and in particular relates to an air outlet structure of a commercial air conditioner. Background Art

[0002] Common air outlet modes for air conditioners include: directional air outlet: fixed wind direction, suitable for rapid cooling, but may cause uneven heating and cooling; up and down swing: the fan swings up and down to distribute the cold air more evenly, but may cause certain noise; left and right swing: the fan swings left and right to cover a larger area, but the air outlet direction may not be concentrated enough. At the same time, the air outlets for air conditioners mainly include front air outlet: mainly used to blow air directly into the room; upper air outlet: generally near the ceiling, suitable for circulating air; side air outlet: common in cabinet air conditioners, providing horizontal wind flow; lower air outlet: some air conditioners are designed with bottom air outlets, suitable for air flow distribution in the ground area. At the same time, in some commercial air conditioners, in order to ensure the appearance, most of them will use hidden air outlets and bury the air outlet inside the wall.

[0003] In order to ensure the effect of rapid cooling and heating, the existing air conditioner will use left and right swing and up and down swing to adjust the wind direction, but this requires two driving devices to be controlled separately. At the same time, most general commercial air conditioners are used in large spaces. The air flow blown out by the existing air outlet structure is weak, which will cause temperature difference in the overall space. Large spaces do not require precise left and right and up and down wind direction adjustment. At the same time, after long-term use, the fan blades of the air outlet are not convenient to disassemble and are difficult for non-professionals to handle, which makes it difficult to clean the fan blades of the air outlet. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an air outlet structure for a commercial air conditioner.

[0005] The technical solution adopted to solve the above technical problems is: to provide an air outlet structure of a commercial air conditioner, including an air outlet shell mechanism, one side of the air outlet shell mechanism is fixedly connected to a side shell, a swing drive mechanism is installed inside the side shell, and an up and down swing mechanism is installed at the front end of the inner wall of the air outlet shell mechanism;

[0006] The rear end of the up-and-down swing mechanism is engaged with a first air guide mechanism, the rear end of the inner wall of the air outlet shell mechanism is provided with a left-and-right swing mechanism, the rear end of the left-and-right swing mechanism is engaged with a second air guide mechanism, and the front end surface of the air outlet shell mechanism is fixedly connected to a wall sealing plate.

[0007] Furthermore, the air outlet housing mechanism comprises an air outlet shell body arranged inside the wall body, a top blocking cover is clamped on the top of the air outlet shell body, and a side blocking cover is clamped on one side of the air outlet shell body.

[0008] Through the above technical solution, when disassembling and cleaning, the entire air outlet structure can be taken out, and the fan blades in the up and down swing mechanism and the left and right swing mechanism can be taken out by simply removing the top blocking cover and the side blocking cover.

[0009] Furthermore, the top and one side of the air outlet shell are provided with through holes corresponding to the top blocking cover and the side blocking cover, and the top blocking cover and the side blocking cover are fixed to the air outlet shell by screws.

[0010] Through the above technical solution, it is ensured that the top sealing cover and the side sealing cover are fixed by multiple screws. The top sealing cover and the side sealing cover can play a role of limiting blocking during installation to ensure the stability of the up and down swing mechanism and the left and right swing mechanism.

[0011] Furthermore, the swing drive mechanism respectively includes an internal threaded sleeve and a fixed rotating shaft fixedly connected to one side of the air outlet shell mechanism close to the side shell body, the internal threaded sleeve and the fixed rotating shaft are rotatably connected to a synchronous wheel, a synchronous belt is installed between the two synchronous wheels, and the two synchronous wheels are respectively fixedly connected to a single-hole chuck and a first bevel gear plate on a side away from each other, one end of the internal threaded sleeve is spirally connected to a limiting nut, the center of one side of the first bevel gear plate is fixedly connected to a square sleeve, and one side of the inner wall of the side shell body is respectively fixedly connected to a driving motor and a rotating support plate, the output end of the driving motor is fixedly connected to a square clamping block, one end of the rotating support plate is rotatably connected to a second bevel gear plate, the top outer side of the second bevel gear plate is fixedly connected to a clamping rod, the top center of the second bevel gear plate is fixedly connected to a limiting stud, and the limiting stud is spirally connected to a limiting nut plate.

[0012] Through the above technical solution, when adjusting the wind direction to achieve rapid cooling or heating, the driving motor drives the square clamp block to rotate, thereby driving the second bevel gear disk meshing therewith, and at the same time drives another synchronous wheel to rotate through the synchronous belt. The rotation of the second bevel gear disk will pull the fan blades in the left and right swinging mechanism to swing through the clamp rod, thereby achieving left and right adjustment of the wind direction. At the same time, when another synchronous wheel drives the single-hole clamp to rotate, it will drive the fan blades in the up and down swinging mechanism to swing through the single-hole clamp, thereby achieving up and down adjustment of the wind direction.

[0013] Furthermore, the up and down swinging mechanism includes a first mechanism shell installed at the front end of the inner wall of the air outlet shell mechanism, and the two sides of the first mechanism shell are respectively rotatably connected with multiple first clamping shafts and multiple second clamping shafts, one end of the multiple second clamping shafts are fixedly connected with a double-headed connecting sleeve rod, and the other ends of the multiple double-headed connecting sleeve rods are rotatably connected with multi-axis connecting rods, and the first fan blades are clamped between the multiple first clamping shafts and the multiple corresponding second clamping shafts.

[0014] Through the above technical solution, under the drive of the swing drive mechanism, the multi-axis connecting rod is driven to move up and down through the engagement of the single-hole chuck and the multi-axis connecting rod, and then the rotation of the multiple first fan blades is achieved by driving the multiple double-headed connecting sleeves and the corresponding multiple first clamping shafts. When disassembling, the multiple second clamping shafts are removed from the side sealing cover, and then the multiple first fan blades can be removed.

[0015] Furthermore, a plurality of round shaft blocks corresponding to the double-headed connecting sleeve rods are fixedly connected to one side of the multi-axis connecting rod, and a round shaft block is also arranged at the center of the other side of the multi-axis connecting rod.

[0016] Through the above technical scheme, it is ensured that the multi-axis connecting rod can be connected to the single-hole chuck and multiple double-head connecting sleeve rods, and the centers of the single-hole chuck and the multiple double-head connecting sleeves are on the same straight line, and the position of the opening of the single-hole chuck is equal to the length of the single-hole chuck from the center of the circle. Therefore, the trajectories of the circular shaft blocks on both sides of the multi-axis connecting rod are the same, ensuring real-time adjustment and steering.

[0017] Furthermore, the first guide mechanism includes two first triangular guide plates and a plurality of first central guide plates engaged at the rear end of the up and down swing mechanism, and first side plates are fixedly connected between both sides of the two first triangular guide plates and the plurality of first central guide plates.

[0018] Through the above technical solution, the airflow is pressurized through the two first triangular guide plates and the first central guide plate, and the airflow is blown out after being pressurized and accelerated. The up and down swing wind is adjusted by the first fan blade, and when the first fan blade rotates to the maximum angle, the rear end of the first fan blade will fit on the corresponding first triangular guide plate and the first central guide plate, thereby ensuring that the airflow can be completely guided by the first fan blade, thereby improving the efficiency of the guide.

[0019] Furthermore, the left and right swing mechanism includes a second mechanism shell installed at the rear end of the inner wall of the air outlet shell mechanism, the top of the second mechanism shell is engaged with a top clamping plate, the bottom inner surface of the second mechanism shell and the bottom of the top clamping plate are rotatably connected with multiple third clamping shafts, second fan blades are engaged between the corresponding multiple third clamping shafts between the second mechanism shell and the top clamping plate, the rear end centers of the multiple second fan blades are fixedly connected with connecting shafts, a driving long rod is arranged between the multiple connecting shafts, one end of the driving long rod is spirally connected with a double-headed threaded rod, and the other end of the double-headed threaded rod is spirally connected with a single-hole connecting rod.

[0020] Through the above technical solution, under the drive of the swing drive mechanism, the rotation of the second bevel gear disk will pull the single-hole connecting rod through the clamping rod, and then pull the driving long rod to move through the double-headed threaded rod, and through the rotation connection of the driving long rod and multiple connecting shaft rods, it can drive multiple second fan blades to rotate and begin to adjust the left and right direction of the airflow.

[0021] Furthermore, the driving long rod and the single-hole connecting rod are both provided with threaded holes corresponding to the double-headed threaded rod at one end close to each other, and the length of the threaded hole in the driving long rod is smaller than the length of the threaded hole in the single-hole connecting rod.

[0022] Through the above technical solution, when disassembling the second fan blades, the top clamping plate is removed at the top sealing cover, so that the multiple third clamping shafts at the bottom of the top clamping plate are disengaged from the corresponding second fan blades, and then the overall second air guide mechanism is removed, and the double-headed threaded rod is rotated so that one end is completely screwed into the single-hole connecting rod, and then the other end of the double-headed threaded rod is disengaged from the driving long rod, and the multiple second fan blades, multiple connecting shafts and the driving long rod are pulled upward through the opening at the top of the second mechanism housing as a whole, so that the bottoms of the multiple second fan blades are disengaged from the multiple third clamping shafts, and then the multiple second fan blades can be taken out for cleaning.

[0023] Furthermore, the second air guide mechanism includes two second triangular air guide plates and a plurality of second central air guide plates engaged at the rear ends of the left and right swing mechanisms, and a second side plate is fixedly connected between both sides of the two second triangular air guide plates and the plurality of second central air guide plates.

[0024] Through the above technical solution, when the air conditioner blows out air, it will pass through two second triangular guide plates and multiple second center guide plates, and due to its structure, it can achieve air pressurization, increase the speed of the airflow, and realize the left and right direction of the air outlet through the guidance of the second fan blade. When the second fan blade rotates to the maximum angle, the rear end of the second fan blade will fit the corresponding second triangular guide plate and the second center guide plate, thereby ensuring that the airflow can be completely guided by the second fan blade to the blowing direction, thereby improving the cooling or heating effect.

[0025] The beneficial effects of the present invention are as follows: (1) The present invention designs an air outlet housing mechanism, an up-and-down swing mechanism, and a left-and-right swing mechanism. When disassembling and cleaning, it is only necessary to remove the top blocking cover and the side blocking cover respectively, remove the multiple second clamping shafts from the side blocking cover, and then remove the multiple first fan blades. Remove the top clamping plate at the top blocking cover, and then remove the overall second air guide mechanism. Rotate the double-headed threaded rod so that one end is completely screwed into the single-hole connecting rod. The multiple second fan blades, the multiple connecting shafts, and the long driving rod are pulled upward through the opening at the top of the second mechanism housing as a whole. Finally, the multiple second fan blades can be taken out, thereby realizing rapid disassembly and cleaning of the fan blades. (2) The present invention designs a first air guide mechanism and a second air guide mechanism. When blowing air, the second triangular guide plate, the second central guide plate, the first triangular guide plate and the first central guide plate are used to increase the air pressure, thereby increasing the air flow speed and improving the air outlet capacity of the air conditioner. At the same time, when the first blade and the second blade are rotated to the maximum angle, the rear ends of the first blade and the second blade will respectively fit the inner walls of the first guide mechanism and the second guide mechanism, thereby achieving that the air flow can be completely guided by the first blade and the second blade to the blowing direction, thereby improving the cooling or heating effect; (3) The present invention drives the up and down swing mechanism and the left and right swing mechanism by designing a swinging wind driving mechanism. In the case of not pursuing fixed-point blowing, swinging blowing is achieved through a single driving mechanism, and does not affect subsequent disassembly and other issues.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] like Figure 1-Figure 4 As shown, an air outlet structure of a commercial air conditioner in this embodiment includes an air outlet shell mechanism 1, and the air outlet shell mechanism 1 includes an air outlet shell 101 arranged inside a wall body, and a top blocking cover 102 is clamped on the top of the air outlet shell 101, and a side blocking cover 103 is clamped on one side of the air outlet shell 101. When disassembling and cleaning, the entire air outlet structure is taken out, and the fan blades in the up-and-down swing mechanism 4 and the left-and-right swing mechanism 6 can be taken out by removing the top blocking cover 102 and the side blocking cover 103. The top and side blocking covers 102 and 103 of the air outlet shell 101 are removed. One side is provided with through holes corresponding to the top sealing cover 102 and the side sealing cover 103, and the top sealing cover 102 and the side sealing cover 103 are fixed to the air outlet shell 101 by screws, ensuring that the top sealing cover 102 and the side sealing cover 103 are fixed by multiple screws. The top sealing cover 102 and the side sealing cover 103 can play a role of limiting and blocking during installation to ensure the stability of the up and down swinging mechanism 4 and the left and right swinging mechanism 6. One side of the air outlet shell mechanism 1 is fixedly connected to the side shell 2.

[0047] like Figure 1-Figure 8 As shown, a swing drive mechanism 3 is installed inside the side shell 2, and the swing drive mechanism 3 includes an internal threaded sleeve 301 and a fixed shaft 302 fixedly connected to the side of the air outlet shell mechanism 1 close to the side shell 2, and a synchronous wheel 303 is rotatably connected to the internal threaded sleeve 301 and the fixed shaft 302, and a synchronous belt 304 is installed between the two synchronous wheels 303. The two synchronous wheels 303 are respectively fixedly connected with a single-hole chuck 305 and a first bevel gear disc 306 on the sides away from each other, one end of the internal threaded sleeve 301 is spirally connected to a limiting nut 307, and a square sleeve 308 is fixedly connected to the center of one side of the first bevel gear disc 306, and a driving motor 309 and a rotating support plate 311 are respectively fixedly connected to one side of the inner wall of the side shell 2, and the output end of the driving motor 309 is fixedly connected to a square clamp block 310, and the rotating support plate 311 One end is rotatably connected to a second bevel gear plate 312, and a clamping rod 313 is fixedly connected to the outer side of the top of the second bevel gear plate 312. The top center of the second bevel gear plate 312 is fixedly connected to a limiting stud 314, and a limiting nut plate 315 is spirally connected to the limiting stud 314. When the wind direction is adjusted to achieve rapid cooling or heating, the driving motor 309 drives the square clamping block 310 to rotate, thereby driving the second bevel gear plate 312 meshing therewith, and at the same time drives the other synchronous wheel 303 to rotate through the synchronous belt 304. The rotation of the second bevel gear plate 312 will pull the fan blades in the left and right swinging mechanism 6 to swing through the clamping rod 313, thereby achieving left and right adjustment of the wind direction. At the same time, when another synchronous wheel 303 drives the single-hole chuck 305 to rotate, the fan blades in the up and down swinging mechanism 4 will be driven to swing through the single-hole chuck 305, thereby achieving up and down adjustment of the wind direction.

[0048] like Figure 1-Figure 10As shown, an up-and-down swing mechanism 4 is installed at the front end of the inner wall of the air outlet shell mechanism 1, and the up-and-down swing mechanism 4 includes a first mechanism shell 401 installed at the front end of the inner wall of the air outlet shell mechanism 1, and multiple first clamping shafts 402 and multiple second clamping shafts 403 are rotatably connected on both sides of the first mechanism shell 401, and one end of the multiple second clamping shafts 403 is fixedly connected with a double-headed connecting sleeve rod 404, and the other ends of the multiple double-headed connecting sleeve rods 404 are rotatably connected. A multi-axis connecting rod 405 is connected between the other ends of the multiple double-headed connecting sleeve rods 404, and a first fan blade 406 is clamped between the multiple first clamping shafts 402 and the multiple corresponding second clamping shafts 403. Under the drive of the swing drive mechanism 3, the multi-axis connecting rod 405 is driven to move up and down through the clamping of the single-hole clamping disc 305 and the multi-axis connecting rod 405, and then the multiple double-headed connecting sleeve rods 404 are driven to move up and down. And the corresponding multiple first clamping shafts 402 are used to drive the rotation of multiple first fan blades 406. During disassembly, the multiple second clamping shafts 403 are removed from the side blocking cover 103, and then the multiple first fan blades 406 can be removed. One side of the multi-axis connecting rod 405 is fixedly connected with multiple circular shaft blocks corresponding to the double-headed connecting sleeve rod 404, and the center of the other side of the multi-axis connecting rod 405 is also provided with a circular shaft block, ensuring that the multi-axis connecting rod 405 can be connected to the single-hole chuck 305 and the multiple double-headed connecting sleeves 404, and the centers of the single-hole chuck 305 and the multiple double-headed connecting sleeves are on the same straight line, and the position of the opening of the single-hole chuck 305 is equal to the length of the single-hole chuck 305 from the center of the circle. Therefore, the trajectories of the circular shaft blocks on both sides of the multi-axis connecting rod 405 are the same, ensuring real-time adjustment of the steering.

[0049] like Figure 1-Figure 13 As shown, the rear end of the up and down swing mechanism 4 is engaged with the first guide mechanism 5, and the first guide mechanism 5 includes two first triangular guide plates 502 and multiple first center guide plates 503 engaged with the rear end of the up and down swing mechanism 4, and the two sides of the two first triangular guide plates 502 and the multiple first center guide plates 503 are fixedly connected with the first side plates 501, and the airflow is pressurized through the two first triangular guide plates 502 and the first center guide plates 503, and the airflow is blown out after being pressurized and accelerated, and the up and down swing wind is regulated by the first fan blade 406, and when the first fan blade 406 rotates to the maximum angle, the rear end of the first fan blade 406 will fit on the corresponding first triangular guide plate 502 and the first center guide plate 503, thereby ensuring that the airflow can be completely guided by the first fan blade 406, thereby improving the efficiency of the guide.

[0050] like Figure 1-Figure 18As shown, a left-right swing mechanism 6 is provided at the rear end of the inner wall of the air outlet housing mechanism 1, and the left-right swing mechanism 6 includes a second mechanism housing 601 installed at the rear end of the inner wall of the air outlet housing mechanism 1, a top card plate 602 is engaged with the top of the second mechanism housing 601, a plurality of third card shafts 603 are rotatably connected to the bottom inner surface of the second mechanism housing 601 and the bottom of the top card plate 602, and a second fan blade 604 is engaged between the corresponding plurality of third card shafts 603 between the second mechanism housing 601 and the top card plate 602, and a plurality of second fan blades 604 are engaged. 04 is fixedly connected to the rear end center with a connecting shaft 605, and a driving long rod 606 is arranged between the multiple connecting shafts 605. One end of the driving long rod 606 is spirally connected to a double-headed threaded rod 607, and the other end of the double-headed threaded rod 607 is spirally connected to a single-hole connecting rod 608. When driven by the swing wind driving mechanism 3, the rotation of the second bevel gear disc 312 will pull the single-hole connecting rod 608 through the clamping rod 313, and then pull the driving long rod 606 to move through the double-headed threaded rod 607. The rotation connection realizes driving the plurality of second blades 604 to rotate, and starts to adjust the left and right directions of the airflow. The driving long rod 606 and the single-hole connecting rod 608 are provided with threaded holes corresponding to the double-headed threaded rod 607 at the ends close to each other, and the length of the threaded hole in the driving long rod 606 is smaller than the length of the threaded hole in the single-hole connecting rod 608. When disassembling the second blade 604, the top clamping plate 602 is removed at the top blocking cover 102, so that the plurality of third clamping shafts 603 at the bottom of the top clamping plate 602 are all separated from the corresponding third clamping shafts The second fan blades 604 are engaged, and then the overall second air guide mechanism 7 is removed, the double-headed threaded rod 607 is rotated so that one end is completely screwed into the single-hole connecting rod 608, and then the other end of the double-headed threaded rod 607 is disengaged from the driving long rod 606, and the multiple second fan blades 604, the multiple connecting shafts 605 and the driving long rod 606 are pulled upward through the opening at the top of the second mechanism shell 601 as a whole, so that the bottom of the multiple second fan blades 604 is disengaged from the engagement of the multiple third clamping shafts 603, and then the multiple second fan blades 604 can be taken out for cleaning.

[0051] like Figure 1-Figure 16As shown, the rear end of the left and right swing mechanism 6 is engaged with a second guide mechanism 7, and the second guide mechanism 7 includes two second triangular guide plates 702 and multiple second center guide plates 703 engaged with the rear end of the left and right swing mechanism 6, and the two sides of the two second triangular guide plates 702 and the multiple second center guide plates 703 are fixedly connected with a second side plate 701. When the air conditioner is discharging air, it will pass through the two second triangular guide plates 702 and the multiple second center guide plates 703, and because of its structure, the air is pressurized and the air speed is increased, and the left and right directions of the air outlet are achieved through the guidance of the second fan blade 604. When the second fan blade 604 rotates to the maximum angle, the rear end of the second fan blade 604 will fit the corresponding second triangular guide plate 702 and the second center guide plate 703, thereby ensuring that the airflow can be completely guided by the second fan blade 604 to the blowing direction, thereby improving the cooling or heating effect, and the front end surface of the air outlet shell mechanism 1 is fixedly connected with a wall sealing plate 8.

[0052] The working principle of this embodiment is as follows. When in use, the overall structure is installed inside the wall. When the air conditioner is blowing out air, it will pass through the two second triangular guide plates 702 and the plurality of second central guide plates 703. Due to its structure, the air is pressurized, the air velocity is increased, and the left and right directions of the air are achieved through the guidance of the second fan blades 604. Then, the air is pressurized through the two first triangular guide plates 502 and the first central guide plate 503. The airflow is pressurized and accelerated and then blown out. The first fan blades 406 are used to adjust the up and down swing wind.

[0053] When adjusting the wind direction to achieve rapid cooling or heating, the driving motor 309 drives the square block 310 to rotate, thereby driving the second bevel gear plate 312 meshing therewith, and at the same time drives another synchronous wheel 303 to rotate through the synchronous belt 304. The rotation of the second bevel gear plate 312 will pull the single-hole connecting rod 608 through the card rod 313, and then pull the driving long rod 606 to move through the double-headed threaded rod 607. By driving the long rod 606 and the rotation connection of the multiple connecting shafts 605, the multiple second fan blades 604 are driven to rotate, and the airflow begins to be adjusted. The left and right directions are adjusted. At the same time, when another synchronous wheel 303 drives the single-hole chuck 305 to rotate, the multi-axis connecting rod 405 is driven to move up and down through the engagement of the single-hole chuck 305 and the multi-axis connecting rod 405, and then the rotation of the multiple first fan blades 406 is driven by driving the multiple double-headed connecting sleeve rods 404 and the corresponding multiple first clamping shafts 402 to achieve up and down wind adjustment. However, since the up and down swing mechanism 4 and the left and right swing mechanism 6 are connected and driven by the swing wind driving mechanism 3, only two diagonal wind directions can be achieved when the wind direction swings;

[0054] When disassembling and cleaning, take out the overall air outlet structure, remove the top blocking cover 102 and the side blocking cover 103 respectively, remove the multiple second clamping shafts 403 from the side blocking cover 103, and then remove the multiple first fan blades 406, remove the top clamping plate 602 at the top blocking cover 102, and then make the multiple third clamping shafts 603 at the bottom of the top clamping plate 602 disengage from the corresponding second fan blades 604, and then remove the overall second air guide mechanism 7, rotate the double-headed threaded rod 607 so that one end is completely screwed into the single-hole connecting rod 608, and then make the other end of the double-headed threaded rod 607 disengage from the driving long rod 606, and pull the multiple second fan blades 604, the multiple connecting shafts 605 and the driving long rod 606 upward through the opening at the top of the second mechanism shell 601 as a whole, so that the bottoms of the multiple second fan blades 604 are disengaged from the engagement of the multiple third clamping shafts 603, and then the multiple second fan blades 604 can be taken out for cleaning.
