Description

Technical Field

[0001] The present invention relates to a technical field, and in particular to an air conditioning unit with a no-dead-angle air outlet function. Background Art

[0002] In the field of modern air conditioning equipment, especially in indoor temperature and air quality control, air conditioning units play a vital role. Traditional air conditioning systems usually use fixed outlet directions to deliver hot and cold air to the room. This design can easily lead to airflow dead spots, which in turn causes significant indoor temperature differences and affects user comfort.

[0003] The patent publication number CN221648614U discloses a central air-conditioning outlet capable of adjusting the air outlet angle. The air outlet includes a square air outlet tube, the lower end of which is fixedly connected to a cover body, a hollow cavity is provided in the cover body, an air outlet frame is provided in the hollow cavity, and an air guide hood that penetrates the cover body and is fixedly connected to the air outlet frame is fixedly connected to the upper end of the air outlet frame, and the air guide hood is connected to the square air outlet tube. In addition, a sealing groove is provided on one side of the square air outlet tube, and a rubber sealing plate is tightly sleeved inside the sealing groove. A disassembly plate with a handle is fixedly connected to one side of the rubber sealing plate, and a square frame 1, a square frame 2 and a square frame 3 are provided on the other side. When the above patent is in use, the servo motor drives the transmission wheel 1, the transmission wheel 2 and the transmission belt, so that the movable screw can be rotated, thereby driving the rotating rod and the air guide plate to rotate, so as to adjust the air outlet angle. Although this design can adjust the air outlet angle within a certain range, its adjustment range is limited to one plane and cannot achieve all-round airflow coverage, resulting in uneven temperature in the air outlet direction and other directions, and obvious temperature differences, which affects the user experience of the air conditioner. Summary of the invention

[0004] In view of this, the present invention provides an air-conditioning unit with a dead-angle air outlet function, which can overcome the disadvantage that the air outlet of the existing central air-conditioning is in a single direction. Even if the air outlet angle can be adjusted in the same direction, it is difficult to cover positions that need cooling or heating in other directions, resulting in obvious temperature difference between the air outlet direction and other directions.

[0005] The technical solution of the present invention is: an air-conditioning unit with a dead-angle-free air outlet function, comprising a mounting frame, an evaporator coil, a drive motor, a rotating frame, fan blades, a first connecting ring, a connecting membrane, a second connecting ring, a lifting assembly and a filter assembly, the evaporator coil is mounted on the mounting frame, the drive motor is mounted on the mounting frame, the rotating frame is connected to the output shaft of the drive motor, the fan blades are connected to the bottom of the rotating frame, and the evaporator coil is surrounded by the outside of the fan blades, the first connecting ring is vertically connected to the mounting frame at intervals, and the first connecting ring is located on the outside of the evaporator coil, the connecting membrane is connected to the first connecting ring, and the second connecting ring is connected to a side of the connecting membrane away from the first connecting ring, the lifting assembly is used to control the second connecting ring to be lifted and lowered to adjust the angle of the connecting membrane, and the filter assembly is used to filter the air entering the inside of the fan blades.

[0006] In one embodiment, the lifting assembly includes an electric push rod, a lifting ring and a connecting rod. The electric push rod is symmetrically installed on the mounting frame, the lifting ring is connected to the telescopic rod of the electric push rod, the connecting rod is connected to the bottom of the lifting ring at evenly spaced intervals around the circumference, and the second connecting ring is fixedly connected to the connecting rod.

[0007] In one embodiment, the filter assembly includes a mounting frame and a filter screen frame, the mounting frame is connected to the top of the rotating frame, the filter screen frame is connected to the bottom of the mounting frame, and the filter screen frame is located on the inner side of the fan blade.

[0008] In one embodiment, it also includes a rod-shaped linear motor, a mounting ring and bristles. The rod-shaped linear motor is installed at the top of the mounting frame, the mounting ring is connected to the mover of the rod-shaped linear motor, the bristles are connected to the outer wall of the mounting ring at circumferential intervals, and the bristles are in contact with the inner wall of the filter frame.

[0009] In one embodiment, it also includes a rubber ring, a connecting frame and a fixing rod. The rubber ring is slidably connected to the guide rail of the rod-shaped linear motor, the connecting frame is connected to the rubber ring, the fixing rod is symmetrically connected to the top of the mounting ring, and the fixing rod is slidably connected to the connecting frame.

[0010] In one embodiment, it also includes a winch, a connecting block and a collecting frame. The winch is symmetrically connected to the bottom of the mounting frame, the connecting block is connected to the end of the wire rope of the winch, the collecting frame is connected to the connecting block, and the collecting frame is located directly below the filter frame.

[0011] In one of the embodiments, it also includes a hollow tube and a positioning block. The hollow tube is symmetrically connected to the bottom of the mounting frame, the positioning block is connected to the inside of the hollow tube, and the wire rope of the winch slides through the side of the hollow tube and the inside of the positioning block. A slot is opened on the connecting block, and the hollow tube is inserted into the slot.

[0012] In one of the embodiments, it also includes tooth blocks, which are evenly spaced around the circumference and connected to the top of the collecting frame.

[0013] The beneficial effects are: 1. The present invention drives the lifting ring to move up and down through the electric push rod, which can drive the second connecting ring to move up and down, thereby adjusting the inclination angle of the connecting membrane. Since the inclination angle of the connecting membrane gradually increases from top to bottom, and the angle of each connecting membrane can be flexibly adjusted according to the needs of the indoor space, it can ensure that the cold and hot air can evenly cover every corner of the room, avoiding the problem of dead corners of air supply caused by the single air outlet direction of traditional air conditioners. This design can not only improve the uniformity of indoor temperature, but also significantly improve the comfort of users.

[0014] 2. The present invention drives the mounting ring to reciprocate up and down through a rod-shaped linear motor. The bristles on the mounting ring can effectively brush off dust and other impurities attached to the filter frame during the descent process. When the bristles contact the tooth blocks, the tooth blocks will scrape off the residual dust on the bristles to ensure that the dust eventually falls into the collection frame. In addition, the design of the fixed rod and the connecting frame allows the bristles to remain in a bent state during the ascent process to prevent the bristles from bringing dust and other impurities back to the filter frame.

[0015] 3. The winch of the present invention can control the lifting and lowering of the connecting block through the wire rope, thereby driving the collection frame to move up and down. When a certain amount of dust accumulates in the collection frame, the winch can loosen the wire rope to allow the collection frame to drop to a suitable height due to gravity, making it convenient for users to clean. The design of the hollow tube and the positioning block can ensure that the wire rope always remains in a vertical state to prevent the collection frame from tipping over during the descent. After cleaning, the winch reels in the wire rope again to lift and reset the collection frame. This design not only simplifies the dust cleaning process, but also ensures the stability and safety of the entire dust collection system, thereby improving user convenience.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0027] Embodiment: An air conditioning unit with a dead angle-free air outlet function includes a compressor, a condenser and an expansion valve. The compressor is used to compress the refrigerant into a high-temperature and high-pressure gas, and then the gas enters the condenser, where it is cooled by the outside air or water and condensed into a liquid state, while dissipating heat to the external environment. Then, when the liquid refrigerant passes through the expansion valve, the pressure drops sharply, and the temperature also decreases, forming a low-temperature and low-pressure liquid and gas mixture. The above-mentioned air conditioning principle is the prior art and will not be described in detail here, and the compressor, condenser and expansion valve are not shown in the figure; Figure 1-Figure 5As shown, it also includes a mounting frame 1, an evaporator coil 2, a driving motor 3, a rotating frame 4, fan blades 5, a first connecting ring 6, a connecting membrane 7, a second connecting ring 8, a lifting component and a filtering component. The evaporator coil 2 is installed at the lower part of the mounting frame 1. The evaporator coil 2 is used for an external expansion valve. The above-mentioned low-temperature and low-pressure liquid and gas mixture will flow into the evaporator coil 2. The mixture in the evaporator coil 2 will absorb the heat of the indoor air and evaporate, so that the air flowing through the surface of the evaporator coil 2 is cooled. The driving motor 3 is installed on the upper part of the mounting frame 1. The output shaft of the driving motor 3 is connected to the rotating frame 4. The rotating frame 4 is hollow, and the bottom of the rotating frame 4 is an open design. The bottom of the rotating frame 4 is connected to the fan blades 5. The fan blades 5 are annular in design, so that when the driving motor 3 drives the rotating frame 4 and the fan blades 5 to rotate, the fan blades 5 can generate a 360-degree wind force blowing outward. Surrounding the outside of the fan blade 5, so that the wind blown outward by the fan blade 5 can pass through the cooling of the surface of the evaporator coil 2 and be dispersed into the room, four first connecting rings 6 are vertically evenly connected on the mounting frame 1, and the first connecting ring 6 is located on the outside of the evaporator coil 2, and each first connecting ring 6 is connected to the outside of a connecting membrane 7, the shape of the connecting membrane 7 is annular, and each connecting membrane 7 is connected to the outside of a second connecting ring 8, the connecting membrane 7 is inclined, and the inclination angle of the connecting membrane 7 gradually increases from top to bottom, a larger inclination angle will reduce the horizontal diffusion range of the wind, and a smaller inclination angle will make the wind spread more widely, the lifting component is used to control the lifting of the second connecting ring 8, and can flexibly adjust the angle of the connecting membrane 7, so as to optimize the distribution of wind force and ensure that the hot and cold air can evenly cover various areas of the room, and the filtering component is used to filter the air entering the fan blade 5.

[0028] like Figure 4 As shown, the lifting assembly includes an electric push rod 9, a lifting ring 10 and a connecting rod 11. The electric push rods 9 are symmetrically installed on the upper part of the mounting frame 1. The lifting ring 10 is connected between the telescopic rods of the two electric push rods 9. A plurality of connecting rods 11 are circumferentially slidably connected to the mounting frame 1. The upper ends of the connecting rods 11 are fixedly connected to the lifting ring 10, and each second connecting ring 8 is fixedly connected to the connecting rod 11.

[0029] like Figure 5 As shown, the filter assembly includes an installation frame 12 and a filter mesh frame 13. The installation frame 12 is connected to the top of the rotating frame 4, and the filter mesh frame 13 is connected to the bottom of the installation frame 12. The filter mesh frame 13 is located on the inner side of the fan blade 5 to filter the air entering the fan blade 5.

[0030] First, install the mounting frame 1 on the indoor ceiling, and then start the air conditioning unit. The low-temperature and low-pressure liquid and gas mixture passing through the expansion valve will flow into the evaporator coil 2, and absorb the heat of the indoor air to evaporate. At the same time, the driving motor 3 will drive the rotating frame 4 and the fan blades 5 to rotate, and the high-temperature air in the room will enter the inner side of the fan blades 5 through the filter frame 13. The filter frame 13 plays a filtering role, and the rotation of the fan blades 5 will generate wind force that spreads in all directions. The wind force will quickly cool down the surface of the evaporator coil 2. The cooled air will pass between each two adjacent connecting membranes 7 and return to the room. Since the cold air is diffused in all directions, it can be transported to all directions in the room at the same time, and, Since the inclination angle of each connecting membrane 7 is inconsistent, the angle of cold air blown out between each two adjacent connecting membranes 7 is inconsistent, so that different heights and different areas in the room can be cooled synchronously, so as to achieve the purpose of uniform cooling of the room and avoid the problem of obvious temperature difference in the room; according to the area and needs of the room, the electric push rod 9 can drive the lifting ring 10 and the connecting rod 11 to lift and lower to adjust the height of the second connecting ring 8, thereby changing the inclination angle of the connecting membrane 7. Although the overall inclination trend of the connecting membrane 7 is gradually increasing from top to bottom, the specific angle of each connecting membrane 7 can be flexibly adjusted through the adjustment of the lifting component to ensure that the cold air can evenly cover all areas of the room.

[0031] like Figure 6 and Figure 7 As shown, it also includes a rod-shaped linear motor 14, a mounting ring 15, bristles 16, a rubber ring 17, a connecting frame 18 and a fixing rod 19. The rod-shaped linear motor 14 is installed on the top of the mounting frame 12. The mounting ring 15 is connected to the mover of the rod-shaped linear motor 14. The outer wall of the mounting ring 15 is connected with bristles 16 at intervals in the circumferential direction, and the bristles 16 are in contact with the inner wall of the filter frame 13. The guide rail of the rod-shaped linear motor 14 is slidably connected with a rubber ring 17. The outer wall of the rubber ring 17 is connected to the connecting frame 18, and the rubber ring 17 is connected to the rod-shaped linear motor. The friction between the guide rails of the machine 14 is large and sufficient to overcome the gravity of the connecting frame 18, so that the rubber ring 17 and the connecting frame 18 will not fall down due to gravity. Four fixing rods 19 are symmetrically connected to the top of the mounting ring 15, and the four fixing rods 19 are all slidably connected to the connecting frame 18. Round blocks are set at the upper ends of the four fixing rods 19, and the diameter of the round blocks is larger than the diameter of the fixing rods 19. When the fixing rods 19 descend to the point where the round blocks on them contact the top of the connecting frame 18, the round blocks will squeeze the connecting frame 18 and move downward synchronously with the fixing rods 19.

[0032] like Figure 8 and Fig. 9As shown, it also includes a winch 20, a connecting block 21, a collecting frame 22, a hollow tube 23, a positioning block 24 and a tooth block 26. The winch 20 is symmetrically installed at the bottom of the mounting frame 1. The ends of the wire ropes of the two winches 20 are connected to the connecting blocks 21. The collecting frame 22 is connected between the two connecting blocks 21. The top of the collecting frame 22 is an open design, and the collecting frame 22 is sleeved on the lower end of the filter frame 13. The bottom of the mounting frame 1 is symmetrically connected to the hollow tube 23. The hollow tube 23 is located on the inner side of the winch 20, and the bottoms of the two hollow tubes 23 are both open. The two hollow tubes 23 are connected with positioning blocks 24 inside, and the wire rope of the winch 20 slides through the side of the hollow tube 23 and the middle of the positioning block 24 in turn. Slots 25 are opened on the two connecting blocks 21, and the lower ends of the hollow tubes 23 are inserted in the slots 25. A plurality of tooth blocks 26 are connected to the top of the collecting frame 22 at even intervals in the circumferential direction.

[0033] As the use time increases, dust and other impurities will gradually accumulate on the inner wall of the filter frame 13. At this time, the mounting ring 15 can be driven by the rod-shaped linear motor 14 to reciprocate up and down. When the mounting ring 15 moves downward, the mounting ring 15 can drive the bristles 16 and the fixing rod 19 to move downward. The round block on the fixing rod 19 will squeeze the connecting frame 18 and the rubber ring 17 to move downward synchronously. When the bristles 16 fall to contact with the inner wall of the filter frame 13, the bristles 16 can brush down the dust and other impurities adhering to the inner wall of the filter frame 13, so that the dust and other impurities fall into the collection frame 22. When the bristles 16 fall to contact with the tooth block 26, the tooth block 26 can brush the dust and other impurities adhering to the bristles. The dust and other impurities on 16 are scraped off and fall into the collection frame 22; when the mounting ring 15 moves upward, the mounting ring 15 can drive the bristles 16 and the fixing rod 19 to move upward, and the round block on the fixing rod 19 will be separated from the top of the connecting frame 18. At this time, the connecting frame 18 and the rubber ring 17 will not move upward temporarily, and the bristles 16 will contact the bottom of the connecting frame 18, and the connecting frame 18 will squeeze the bristles 16 to bend downward, so that the bristles 16 are separated from the inner wall of the filter frame 13, and then the mounting ring 15 will contact the connecting frame 18 and push the connecting frame 18 and the rubber ring 17 to move upward and reset. At this time, the bristles 16 remain in a downward bending state, thereby preventing the bristles 1 6 will brush the dust and other impurities remaining on the inner wall of the filter frame 13 upwards. When the mounting ring 15 moves downward again, it will separate from the connecting frame 18 and drive the bristles 16 and the fixing rod 19 to continue to move downward until the round block on the fixing rod 19 contacts the top of the connecting frame 18 again. At this time, the bristles 16 will detach from the bottom of the connecting frame 18 and return to their original state, ready for the next cleaning action. In this way, the filter frame 13 can be automatically cleaned to prevent dust and other impurities from clogging the filter holes of the filter frame 13 and ensure the filtering performance of the filter frame 13. When a certain amount of dust and other impurities are contained in the collecting frame 22, the winch 20 can be controlled to loosen the wire rope. At this time, The collecting frame 22 will move downward due to gravity and drive the connecting block 21 to move downward, so that the hollow tube 23 is disengaged from the slot 25. Under the action of the positioning block 24, the steel wire rope of the winch 20 can be ensured to always remain in a vertical state and coincide with the axis of the hollow tube 23, thereby preventing the collecting frame 22 from tipping over. When the collecting frame 22 drops to a suitable height, the dust and other impurities in the collecting frame 22 can be manually poured out for cleaning, and then the winch 20 can be controlled to reel in the steel wire rope, which can pull the collecting frame 22 and the connecting block 21 upward to reset. Under the positioning action of the hollow tube 23 and the slot 25, the collecting frame 22 can be accurately mounted on the lower end of the filter frame 13.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
