Description

Technical Field

[0001] This utility model relates to the technical field of multi-split air conditioning equipment, specifically a three-pipe high sensible heat multi-split air conditioning system. Background Technology

[0002] To facilitate independent temperature control of different rooms, multi-split air conditioning systems are often required. Three-pipe high sensible heat multi-split air conditioners are a common type. Utility model patent application CN202320643980.1 discloses a multi-split air conditioner that, by installing a communication converter inside the outdoor unit's control box, can convert the communication protocol of the indoor unit to that of the outdoor unit, maintaining consistency in communication protocols between the two units. Even when the outdoor and indoor units are from different brands, the communication converter allows for communication between the two different brands of outdoor and indoor units, enabling them to connect and operate smoothly. This solution addresses the issue of needing to add extra hardware (such as circuit boards and electronic expansion valve boxes for outdoor or indoor units) to achieve cross-brand connectivity after changing air conditioner manufacturers, significantly reducing costs. According to its publicly available technical solutions, existing multi-split air conditioning systems often experience problems. On the one hand, during heat exchange, the outdoor unit's filters are easily clogged due to the use of the conveyor, reducing airflow speed and hindering heating or cooling efficiency. On the other hand, filter cleaning often cannot be controlled in real-time based on the clogging status of the filter mechanism, leading to delayed cleaning affecting ventilation speed or excessive cleaning increasing energy consumption and wear.

[0003] Therefore, how to design a three-pipe high sensible heat multi-split air conditioning system has become the problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a three-pipe high sensible heat multi-split air conditioning system to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for independent temperature and humidity control of indoor spaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-pipe high sensible heat multi-split air conditioning system, comprising an outdoor unit and a filter cartridge. A support assembly is installed at the bottom of the outdoor unit, the support assembly including a base and a bracket. A ventilation assembly is installed at the top of the outdoor unit, the ventilation assembly including a duct and a first fan. A movable assembly is installed on the duct, the movable assembly including a sliding sleeve and a piston. A rotating assembly is installed inside the filter cartridge, the rotating assembly including a motor and a support rod. An air blowing assembly is installed on the motor, the air blowing assembly including a duct and a second fan.

[0006] Furthermore, the bracket is welded to the top of the base, and the outdoor unit of the air conditioner is installed on the top of the bracket by bolts. The outdoor unit of the air conditioner is a three-pipe high sensible heat multi-split air conditioner outdoor unit.

[0007] Furthermore, the air duct is welded to the top of the outdoor unit of the air conditioner, the fan is installed inside the air duct, a mesh is bolted to the top of the air duct, and the air duct is connected to the inside of the outdoor unit of the air conditioner.

[0008] Furthermore, the bottom of the filter cartridge is bolted to the top of the base, the top of the filter cartridge is bolted to the bottom of the outdoor unit of the air conditioner, one end of the support rod is bolted to the outer side of the motor, and the other end of the support rod is bolted to the bottom of the outdoor unit of the air conditioner.

[0009] Furthermore, the top of the air duct is keyed to the output shaft of the motor, the second fan is installed on the inside of the air duct by bolts, a blowpipe is welded to one end of the air duct, and a blowhole is integrally formed at one end of the blowpipe, the blowhole being clamped on the inner wall of the filter cartridge.

[0010] Furthermore, the sliding sleeve is welded to one side of the air duct, the sliding sleeve is connected to the inner side of the air duct, and the outer side of the piston is clamped on the inner wall of the sliding sleeve.

[0011] Furthermore, a button is bolted to the inner wall of one end of the sliding sleeve, and a through hole is opened at the bottom of the other end of the sliding sleeve. The piston is connected to the inner wall of the other end of the sliding sleeve by a spring.

[0012] Furthermore, the sliding sleeve is connected to the outside through a through hole, and the button is connected to the motor and the fan through wires.

[0013] Beneficial effects: 1. When this three-pipe high sensible heat multi-split air conditioning system is in use, the outdoor unit operates to provide heating or cooling for the indoor unit. Fan 1 generates suction on the outdoor unit through the air duct, causing air to enter the outdoor unit after being filtered by the filter cartridge, thus facilitating heat exchange for the outdoor unit. The motor, supported by the strut, drives the air duct to rotate. Fan 2 draws in the air filtered by the filter cartridge and blows it to the inside of the blow pipe. The airflow passes through the nozzle on the blow pipe and is quickly blown outward from the inner wall of the filter cartridge. Driven by the motor, it also blows dust and impurities around the filter cartridge, effectively preventing filter cartridge blockage and ensuring the ventilation speed of the filter cartridge, thus ensuring the working efficiency of the outdoor unit.

[0014] 2. In this three-pipe high sensible heat multi-split air conditioning system, when the filter cartridges are clogged with dust, causing poor ventilation, the air pressure in the duct drops under the suction of fan one. This causes atmospheric pressure to push the piston to the left through the air vents. The piston stretches the spring and presses the button, which in turn activates fan two and the motor for cleaning. Once the dust on the filter cartridges is removed and ventilation is smooth, the spring pulls the piston to the right, and the motor and fan two stop working. This system avoids both the decrease in ventilation speed due to untimely cleaning of the filter cartridges, which would affect the operation of the outdoor unit, and the over-cleaning of the filter cartridges, which would increase energy consumption and cause wear to the filter cartridges.

[0015] 3. This three-pipe high sensible heat multi-split air conditioning system is reasonably designed, highly efficient and convenient to use, and suitable for independent temperature and humidity control of indoor spaces. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a three-pipe high sensible heat multi-split air conditioning system, including an outdoor unit 1 and a filter cartridge 7. A support assembly is installed at the bottom of the outdoor unit 1, the support assembly including a base 2 and a bracket 3. A ventilation assembly is installed at the top of the outdoor unit 1, the ventilation assembly including a duct 4 and a fan 6. A movable assembly is installed on the duct 4, the movable assembly including a sliding sleeve 8 and a piston 9. A rotating assembly is installed inside the filter cartridge 7, the rotating assembly including a motor 12 and a support rod 13. An air blowing assembly is installed on the motor 12, the air blowing assembly including a duct 14 and a fan 15. The sliding sleeve 8 is welded to one side of the duct 4, the sliding sleeve 8 is connected to the inside of the duct 4. The outer side of the piston 9 is engaged with the inner wall of the sliding sleeve 8. A button 10 is bolted to the inner wall of one end of the sliding sleeve 8. The bottom of the other end of the sliding sleeve 8... A through hole 18 is provided. The piston 9 is connected to the inner wall of the other end of the sliding sleeve 8 through the spring 11. The sliding sleeve 8 is connected to the outside through the through hole 18. The button 10 is connected to the motor 12 and the second fan 15 through the wire. When the filter cartridge 7 is poorly ventilated due to a lot of dust, the air pressure in the air duct 4 drops under the suction of the first fan 6. This causes the atmospheric pressure to squeeze the piston 19 to the left through the air hole 18. The piston 19 stretches the spring 11 and squeezes the button 10, thereby turning on the second fan 15 and the motor 12 to clean the filter cartridge 7. When the dust on the filter cartridge 7 is cleaned and the ventilation is smooth, the spring 11 pulls the piston 9 to the right, and the motor 12 and the second fan 15 stop working. This can avoid the decrease in ventilation speed due to the filter cartridge 7 not being cleaned in time, which would affect the operation of the outdoor unit 1 of the air conditioner. It can also avoid excessive cleaning of the filter cartridge 7, which would increase the energy consumption and wear on the filter cartridge 7.

[0023] In this embodiment, the bracket 3 is welded to the top of the base 2. The outdoor unit 1 is bolted to the top of the bracket 3. The outdoor unit 1 is a three-pipe high sensible heat multi-split air conditioner. The air duct 4 is welded to the top of the outdoor unit 1. The first fan 6 is installed inside the air duct 4. A mesh 5 is bolted to the top of the air duct 4. The air duct 4 is connected to the inside of the outdoor unit 1. The bottom of the filter cartridge 7 is bolted to the top of the base 2. The top of the filter cartridge 7 is bolted to the bottom of the outdoor unit 1. One end of the support rod 13 is bolted to the outside of the motor 12. The other end of the support rod 13 is bolted to the bottom of the outdoor unit 1. The top of the air duct 14 is keyed to the output shaft of the motor 12. The second fan 15 is bolted to the inside of the air duct 14. One end of the air duct 14 is welded with a blower. The blowpipe 16 has an integrally formed nozzle 17 at one end, which is attached to the inner wall of the filter cartridge 7. During use, the outdoor unit 1 of the air conditioner operates to provide heating or cooling for the indoor unit. Fan 1 6 generates suction on the outdoor unit 1 through the air duct 4, causing air to enter the outdoor unit 1 after being filtered by the filter cartridge 7, thus facilitating heat exchange for the outdoor unit 1. The motor 12, supported by the support rod 13, drives the air duct 14 to rotate. Fan 2 15 draws in the air filtered by the filter cartridge 7 and blows it to the inside of the blowpipe 16. The airflow passes through the nozzle 17 on the blowpipe 16 and is quickly blown outward from the inner wall of the filter cartridge 7. Driven by the motor 12, the airflow also blows dust and impurities around the filter cartridge 7, effectively preventing the filter cartridge 7 from becoming clogged and ensuring the ventilation speed of the filter cartridge 7, thereby ensuring the working efficiency of the outdoor unit 1.

[0024] This three-pipe high sensible heat multi-split air conditioning system provides power to all electrical equipment via an external power source. During operation, outdoor unit 1 operates, providing heating or cooling to the indoor unit. Fan 1 6, through air duct 4, generates suction on outdoor unit 1, causing air to pass through filter cartridge 7 before entering the unit for heat exchange. Motor 12, supported by support rod 13, drives air duct 14 to rotate. Fan 2 15 draws in the air filtered by filter cartridge 7 and blows it to the inside of blowpipe 16. The airflow passes through nozzle 17 on blowpipe 16 and is rapidly blown outwards from the inner wall of filter cartridge 7. Driven by motor 12, it also blows dust and impurities around filter cartridge 7, effectively preventing clogging. This effectively ensures the ventilation speed of the filter cartridge 7 and the working efficiency of the outdoor unit 1. When the filter cartridge 7 is poorly ventilated due to excessive dust, the air pressure in the duct 4 drops under the suction of the fan 6. This causes atmospheric pressure to press the piston 19 to the left through the air hole 18. The piston 19 stretches the spring 11 and presses the button 10, thereby turning on the fan 15 and the motor 12 to clean the filter cartridge 7. Once the dust on the filter cartridge 7 is cleaned and ventilation is smooth, the spring 11 pulls the piston 9 to the right, and the motor 12 and the fan 15 stop working. This not only avoids the decrease in ventilation speed due to untimely cleaning of the filter cartridge 7, which would affect the operation of the outdoor unit 1, but also avoids excessive cleaning of the filter cartridge 7, which would increase energy consumption and wear on the filter cartridge 7.
