Description

Technical Field

[0001] The present invention belongs to the technical field of air energy integrated machine, and in particular relates to an air energy integrated machine which is easy to maintain and a working method thereof. Background Art

[0002] An air-energy unit (AHU) is a highly efficient and energy-saving device that combines heating, cooling, and hot water production. It achieves energy transfer through the coordinated operation of outdoor and indoor units. Its core function is to extract free heat energy from the ambient air using the reverse Carnot cycle principle, driving the system with a small amount of electricity to achieve three major functions: stable heating for indoor spaces in winter, efficient cooling and cooling in summer, and the ability to produce domestic hot water year-round. It combines the advantages of energy conservation, environmental protection, safety, reliability, and multi-functional integration. The AHU is structurally divided into two core parts: the outdoor unit includes an evaporator (which absorbs or releases air heat), a compressor (which increases refrigerant energy), a fan (which accelerates air heat exchange), a four-way reversing valve (which switches between cooling and heating modes), and a throttling device (which controls the refrigerant state). The indoor unit houses a built-in condenser (which exchanges heat with the heat exchange medium), a circulating water pump (which drives the heat exchange medium), an air supply system (which processes the air), and a control unit. Some existing models also have an integrated hot water storage tank.

[0003] At present, when the outdoor unit of the air-energy integrated unit is working, it mainly uses fans, compressors and other components to draw outside air into the body, and then extract the heat in the air. During this process, the axial fan directly and continuously sends the outside air to the position of the condenser. However, with long-term operation, a large amount of dust, impurities and other pollutants will gradually accumulate on the surface of the heat exchange fins of the condenser. This dust accumulation phenomenon not only affects the heat exchange efficiency, but may also cause equipment failure and affect the normal operation of the air-energy integrated unit. Therefore, it is necessary to clean and maintain the heat exchange fins on the condenser from time to time.

[0004] The Chinese utility model patent application number is CN202322756273.6, which discloses an evaporator and an air-energy heat pump, including: an evaporator body, the surface of the evaporator body is connected to a grille, the bottom of the evaporator body is connected to a receiving plate, and the bottom of the receiving plate is connected to a plug-in plate; a fixed frame, a fixed cavity is opened inside the fixed frame, and the plug-in plate extends to the inside of the fixed cavity; support plates are fixedly connected to the top two sides of the fixed frame, a placement frame is provided on the top of the support plate, and a driving mechanism is provided inside the placement frame; the driving mechanism includes a second motor provided inside the placement frame, the output end of the second motor is connected to a threaded rod, the surface of the threaded rod is screwed with a moving block, the bottom of the moving block is connected to a connecting block, the connecting block passes through the placement frame and is connected to a brush, and one side of the brush is in contact with the grille.

[0005] The above-mentioned existing air-energy heat pump (air-energy integrated unit) adopts a reciprocating placement frame to drive the brush to move and clean the grille. However, in order to save space and ensure protection, the outdoor unit of the existing air-energy integrated unit usually adopts a highly integrated compact design. The condenser, as a core component, is often placed deep in the casing. Therefore, when cleaning the condenser, it is inconvenient to operate and it is not easy for the brush to directly touch the surface of the heat exchange fins, thereby failing to effectively clean the condenser, reducing the use effect. When deep cleaning the condenser, it may be necessary for the staff to remove a large area of ​​the side panels or top cover, and even remove peripheral components such as the fan and grille. In this case, it is difficult for the staff to find a suitable angle and position for deep cleaning of the heat exchange fins, which greatly increases the difficulty and complexity of maintenance of the outdoor unit. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an air-energy integrated unit that is easy to maintain and its working method, which is used to solve the technical problems raised in the background technology. It can continuously clean the heat exchange fins of the condenser, and the sewage and impurities in the cleaning process can be easily discharged. It can also perform air cooling and blowing on the interior of the outdoor unit body.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] The axial flow fan is installed on the left and right outer walls of the outdoor unit body, and the condenser is installed on the outer walls of the slope on the left and right sides of the outdoor unit body. A double T-shaped inverted frame is provided on the side of the outdoor unit body away from each other of the two condensers, and an in-line sweeping structure is installed inside the double T-shaped inverted frame on the side close to the hollow triangular air inlet box. The in-line sweeping structure contacts the heat exchange fins of the corresponding condenser, and an auger-type sewage discharge structure is installed inside the double T-shaped inverted frame below the in-line sweeping structure. A double-position centrifugal blowing structure is installed on the side of the double T-shaped inverted frame away from the hollow triangular air inlet box. Transmission modules are provided on the left and right outer walls of the double T-shaped inverted frame, and the transmission module is used to drive the in-line sweeping structure, the double-position centrifugal blowing structure and the auger-type sewage discharge structure to work. A motor for driving one of the transmission modules to work is installed on one side wall of the outdoor unit body.

[0009] The following is a further optimization of the above technical solution by the present invention:

[0010] The double T-shaped inverted frame includes two T-shaped frames arranged at intervals along the X-axis direction, the two T-shaped frames are respectively installed on the outdoor unit body, the transmission module is arranged on the outer walls of the two T-shaped frames away from each other, and the in-line sweeping structure, the double-position centrifugal blowing structure, and the auger-type sewage discharge structure are all arranged between the two T-shaped frames.

[0011] Further optimization: the auger-type sewage discharge structure includes a sewage tank fixedly installed between two T-shaped frames in the same X-axis direction, a spiral auger is rotatably installed inside the sewage tank, and a sewage pipe is installed at the bottom end of the sewage tank.

[0012] Further optimization: The double-position centrifugal blowing structure includes an air duct, which is fixedly installed between two T-shaped frames in the same X-axis direction. Centrifugal fans are installed on the top of both sides of the air duct, and the air outlet of the centrifugal fan is connected to the air inlet at the top of the air duct.

[0013] Further optimization: the bottom end of the air duct extends downward at an angle and is provided with an exhaust port.

[0014] Further optimization: The in-line sweeping structure includes a number of sweeping shafts arranged at equal intervals above the sewage tank, the two ends of the sweeping shafts are rotatably connected to the corresponding T-shaped frames, and a number of cleaning bristles are arranged on the outer peripheral surface of the sweeping shafts along their axial and radial arrays.

[0015] Further optimization: A transmission structure is installed between the ends of the same side of the plurality of rolling sweep shafts for interconnecting the plurality of rolling sweep shafts.

[0016] Further optimization: the transmission module includes a secondary speed-increasing sprocket, a primary sprocket, a third speed-increasing sprocket and a fourth speed-increasing sprocket. The input shaft of the centrifugal fan is fixedly connected to the corresponding secondary speed-increasing sprocket, the primary sprocket is rotatably installed on the T-shaped frame, the ends of the topmost roller sweep shaft are fixedly connected to the corresponding third speed-increasing sprocket, the two ends of the spiral auger are fixedly connected to the corresponding fourth speed-increasing sprocket, the same chain is sleeved on the outer circumference of the secondary speed-increasing sprocket, the primary sprocket, the third speed-increasing sprocket and the fourth speed-increasing sprocket, and a sprocket transmission assembly is also installed between the two fourth speed-increasing sprockets in the same Y-axis direction.

[0017] Further optimization: a chain tensioning wheel for tensioning the chain is rotatably mounted on one side outer wall of the T-shaped frame;

[0018] The power output end of the motor is in transmission connection with the central shaft of the primary sprocket.

[0019] The present invention also provides a method for operating an air-energy integrated machine that is easy to maintain. Based on the above-mentioned air-energy integrated machine that is easy to maintain, the method includes the following steps:

[0020] S101: First, ensure that the outdoor unit is powered off and in shutdown. Then, continuously spray cleaning fluid onto the left and right condensers through the external spray pipes. Simultaneously, the motor is turned on. The motor, through the transmission module, synchronously drives the in-line sweep mechanism, auger drainage mechanism, and dual-position centrifugal blower mechanism on the left and right outer walls of the hollow triangular air inlet box.

[0021] S102: The inline sweeping structure rotates at high speed close to the surface of the condenser. The external spray pipe continuously and evenly sprays low-foam cleaning liquid onto the condenser. Under the action of the inline sweeping structure's rotation, the condenser is deeply cleaned.

[0022] S103: The waste liquid mixed with dirt flows along the outer surface of the hollow triangular air inlet box into the auger-type sewage discharge structure. The auger-type sewage discharge structure operates under the drive of the transmission module and pushes the sewage and impurities toward the sewage outlet, so that the sewage and impurities are discharged from the outdoor unit body. During the cleaning and maintenance process, the double-position centrifugal blower structure operates to generate high-speed airflow for air cooling and heat dissipation of the components inside the outdoor unit body.

[0023] S104: After completing the cleaning and maintenance work, the staff stops spraying and runs the in-line sweeping structure and the double-position centrifugal blowing structure for a period of time to dry out the remaining droplets and prevent rust, and then restarts the outdoor unit body.

[0024] The present invention adopts the above technical solution, which has at least the following beneficial effects:

[0025] 1. The in-line roller sweep structure of the present invention can continuously clean the heat exchange fins of the condenser. During the cleaning process, the staff continuously sprays cleaning liquid on the condenser, and the generated sewage is collected in the auger-type sewage discharge structure and discharged. During this process, the motor and transmission module transmit power to the in-line roller sweep structure and the auger-type sewage discharge structure on the left and right sides, and the double-position centrifugal blower structure is started to reduce the internal temperature of the outdoor unit body until a cleaning and maintenance operation is completed.

[0026] 2. The double T-shaped inverted frame of the present invention is directly fixed on the outdoor unit body, so that the in-line rolling sweeping structure always fits the surface of the condenser heat exchange fins. There is no need to disassemble the casing or move other parts during maintenance. The in-line rolling sweeping structure directly cleans the heat exchange fins under the drive of the transmission module, completely avoiding the tedious process of disassembling the casing and the risk of component damage in traditional maintenance. The operating load is greatly reduced, which not only saves maintenance time but also reduces maintenance costs. In addition, the axial rolling design of the in-line rolling sweeping structure allows the cleaning bristles to extend into the gaps between the heat exchange fins, and peel off embedded stubborn dust, oil and flocs during continuous rotation; dynamic rolling sweeping operation is realized, and the dynamic rolling sweeping can efficiently remove dirt in deep dead corners on the condenser and restore the heat exchange efficiency of the heat exchange fins.

[0027] 3. In the present invention, the waste liquid generated when spraying the cleaning liquid and stripping the dirt is collected in real time by the auger-type sewage discharge structure below. The high-concentration sewage can be quickly discharged from the outdoor unit body through the spiral conveying of the spiral auger, avoiding the accumulation of dust-containing wastewater, corrosion of circuits, motors or breeding of mold. At the same time, the design of the transmission module cleverly transmits power to the in-line roller sweeping structure and the auger-type sewage discharge structure on the left and right sides, realizing the coordinated and synchronous operation of the entire cleaning system. The centralized power transmission method not only simplifies the mechanical structure, but also ensures the synchronous movement of various components, avoiding incomplete cleaning or mechanical failure due to asynchrony.

[0028] 4. The introduction of the double-position centrifugal blowing structure in the present invention can significantly reduce the temperature inside the outdoor unit body. By receiving the rotational power from the transmission module and generating a strong blowing effect, air is quickly introduced into the interior of the equipment, taking away excess heat and improving internal heat dissipation conditions. It not only helps to maintain the normal operating temperature of the equipment and extend the service life of the equipment, but also quickly restores the equipment to the best working condition after the cleaning operation is completed.

DETAILED DESCRIPTION

[0039] 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; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] like Figures 1-9 As shown, an air energy integrated machine that is easy to maintain includes an outdoor unit body 1, a hollow triangular air inlet box 2 is fixedly installed in the middle of the outdoor unit body 1, axial fans 3 are installed on both sides of the top of the hollow triangular air inlet box 2, condensers 4 are installed on the slope outer walls on the left and right sides of the hollow triangular air inlet box 2, and double T-shaped inverted frames 5 are respectively provided on the side of the outdoor unit body 1 where the two condensers 4 are away from each other. An in-line rolling sweep structure 6 is installed inside the double T-shaped inverted frame 5 on the side close to the hollow triangular air inlet box 2, and the in-line rolling sweep structure 6 is in contact with the heat exchange fins of the corresponding condenser 4. An auger-type sewage discharge structure 10 is installed inside the double T-shaped inverted frame 5 below the in-line rolling sweep structure 6, and a double-position centrifugal blowing structure 7 is installed on the side of the double T-shaped inverted frame 5 away from the hollow triangular air inlet box 2.

[0041] Transmission modules 8 are provided on the left and right outer walls of the double T-shaped inverted frame 5. The transmission module 8 is used to drive the in-line sweeping structure 6, the double-position centrifugal blowing structure 7 and the auger-type sewage discharge structure 10 to work. A motor 9 for driving one of the transmission modules 8 to work is installed on one side wall of the outdoor unit body 1.

[0042] The double T-shaped inverted frame 5 includes two T-shaped frames 501 arranged at intervals along the X-axis direction. The two T-shaped frames 501 are respectively installed on the outdoor unit body 1. The transmission module 8 is arranged on the outer walls of the two T-shaped frames 501 that are far away from each other. The in-line sweeping structure 6, the double-position centrifugal blowing structure 7, and the auger-type sewage discharge structure 10 are all arranged between the two T-shaped frames 501.

[0043] In this embodiment, the T-shaped frame 501 is made of square-mouthed steel pipes through welding, and the overall structure of the T-shaped frame 501 is in a T-shape.

[0044] In this embodiment, the T-shaped frame 501 can be directly fixedly installed on the outer wall of the outdoor unit body 1 or the hollow triangular air inlet box 2. A rigid support structure can be formed by the T-shaped frame 501, and a square cross beam can be fixedly connected between the two T-shaped frames 501 in the same X-axis direction. The square cross beam is used to improve the overall structural strength of the double T-shaped inverted frame 5, thereby providing a stable bearing base for the in-line sweeping structure 6, the double-position centrifugal blowing structure 7, and the auger-type sewage discharge structure 10. There is no need to disassemble the casing or move parts during maintenance, which completely eliminates the large amount of disassembly and assembly labor and the risk of component damage in traditional maintenance.

[0045] like Figure 5-8 As shown, the auger type sewage discharge structure 10 includes a sewage tank 1001 fixedly installed between two T-shaped frames 501 in the same X-axis direction, a spiral auger 1002 is rotatably installed inside the sewage tank 1001, and a sewage pipe 1003 is installed at the bottom end of the sewage tank 1001.

[0046] In this embodiment, an opening is provided above the sewage tank 1001 , and sewage generated when the in-line sweeping structure 6 is working to scrub the outer surface of the condenser 4 flows into the sewage tank 1001 through the outer surface of the hollow triangular air inlet box 2 .

[0047] The cross section of the sewage tank 1001 is in the shape of an arc plate, and the outer surface of the spiral auger 1002 is adapted to the inner surface of the sewage tank 1001 .

[0048] With this design, the staff sprays cleaning liquid onto the outer surface of the condenser 4 through the spray hose. At this time, the in-line sweeping structure 6 works to wash the heat exchange fins on the condenser 4, thereby achieving deep cleaning of the condenser 4. At this time, the waste liquid mixed with dirt flows into the sewage tank 1001 along the outer surface of the hollow triangular air inlet box 2, and the spiral auger 1002 rotates in the sewage tank 1001 to push the sewage and dirt until the sewage and dirt are discharged through the sewage pipe 1003.

[0049] In this embodiment, the other end of the sewage pipe 1003 can extend to the outside of the outdoor unit body 1, and the sewage and dirt in the sewage tank 1001 are discharged to the outside of the outdoor unit body 1 through the sewage pipe 1003, so that the sewage is completely isolated from the outdoor unit body 1, avoiding secondary contamination after cleaning.

[0050] The double-position centrifugal blowing structure 7 includes an air duct 701, which is fixedly installed between two T-shaped frames 501 in the same X-axis direction. Centrifugal fans 703 are respectively installed at the top of both sides of the air duct 701, and the air outlet of the centrifugal fan 703 is connected to the air inlet at the top of the air duct 701.

[0051] The bottom end of the air duct 701 extends downward at an angle and is provided with an exhaust port 702 ; the exhaust port 702 is arranged downward at an angle to discharge high-speed airflow to achieve air cooling and heat dissipation of other accessories installed below the hollow triangular air inlet box 2 in the outdoor unit body 1 .

[0052] With this design, the centrifugal fan 703 generates high-speed airflow and sends it into the air duct 701. At this time, the air in the air duct 701 is sent out through the exhaust port 702 and blown to the bottom of the hollow triangular air inlet box 2, thereby continuously cooling the accessories inside the outdoor unit body 1.

[0053] like Figure 5-8 As shown, the mechanical action of the in-line sweeping structure 6 is more efficient than traditional manual cleaning, and can continuously maintain the heat dissipation performance of the condenser 4, ensuring efficient operation of the equipment.

[0054] The in-line sweeping structure 6 includes a plurality of sweeping shafts 601 arranged at equal intervals above the sewage tank 1001. The two ends of the sweeping shafts 601 are rotatably connected to the corresponding T-shaped frames 501 respectively. A plurality of cleaning bristles 602 are arranged on the outer peripheral surface of the sweeping shaft 601 along its axial and radial arrays.

[0055] The rotation of the sweeping shaft 601 is used to drive the cleaning bristles 602 to rotate. At this time, the cleaning bristles 602 are in contact with the outer surface of the condenser 4 and are used to clean the outer surface of the heat exchange fins on the condenser 4.

[0056] In this embodiment, a transmission structure 603 is installed between the ends of the plurality of rolling sweep shafts 601 on the same side for interconnecting the plurality of rolling sweep shafts 601 .

[0057] In this embodiment, the transmission structure 603 includes at least one synchronous pulley fixedly mounted on the sweeping shaft 601 near one end thereof on the same side, and a same synchronous belt is sleeved between two adjacent synchronous pulleys.

[0058] With this design, the cooperation of the synchronous pulley and the synchronous belt enables a transmission connection between the upper and lower adjacent rolling sweep shafts 601, thereby enabling a plurality of rolling sweep shafts 601 to achieve a transmission connection and achieve synchronous rotation.

[0059] When one of the sweeping shafts 601 rotates, the transmission structure 603 cooperates to drive the remaining sweeping shafts 601 to rotate synchronously. At this time, the sweeping shaft 601 drives the cleaning bristles 602 to rotate during the rotation, so that the cleaning bristles 602 clean the heat exchange fins on the condenser 4. The mechanical rolling produces a continuous sweeping effect, which is used to deeply clean the condenser 4, including the slope corners and the roots of the heat exchange fins, to achieve full coverage cleaning operation, and thoroughly remove dust, dirt and impurities on the heat exchange fins.

[0060] In addition to this embodiment, the transmission structure 603 can also adopt a transmission pulley and a transmission belt assembly. The transmission pulleys are respectively fixedly installed on the roller sweep shaft 601, and the same transmission belt is arranged between the upper and lower adjacent transmission pulleys. The transmission pulleys and the transmission belt enable multiple roller sweep shafts 601 to be connected by transmission.

[0061] In this embodiment, the rolling sweep shaft 601 of the in-line rolling sweep structure 6 is spaced apart from the outer surface of the condenser 4, and the in-line rolling sweep structure 6 contacts the outer surface of the condenser 4 through the cleaning bristles 602. The cleaning bristles 602 are in the shape of slender fibers. Therefore, the in-line rolling sweep structure 6 does not affect the heat exchange area and heat exchange effect between the condenser 4 and the air, thereby ensuring that the condenser 4 can work normally.

[0062] like Figure 5-8 As shown, the transmission module 8 includes a secondary speed-increasing sprocket 801, a primary sprocket 802, a tertiary speed-increasing sprocket 803 and a fourth-stage sprocket 805. The input shaft of the centrifugal fan 703 is fixedly connected to the corresponding secondary speed-increasing sprocket 801, the primary sprocket 802 is rotatably mounted on the T-shaped frame 501, the ends of the topmost roller sweep shaft 601 are fixedly connected to the corresponding third-stage speed-increasing sprocket 803, and the two ends of the spiral auger 1002 are fixedly connected to the corresponding fourth-stage sprocket 805.

[0063] The same chain 806 is sleeved on the outer circumferences of the secondary speed-increasing sprocket 801 , the primary sprocket 802 , the tertiary speed-increasing sprocket 803 and the fourth sprocket 805 .

[0064] In this design, the primary sprocket 802 serves as the driving sprocket. When the primary sprocket 802 rotates, the secondary speed-increasing sprocket 801, the tertiary speed-increasing sprocket 803 and the fourth speed-increasing sprocket 805 are driven to rotate synchronously through the cooperation of the chain 806.

[0065] The secondary speed increasing sprocket 801 rotates to drive the centrifugal fan 703 to work; the centrifugal fan 703 generates high-speed airflow and is discharged through the exhaust port 702 on the air duct 701, thereby achieving air cooling and heat dissipation for the accessories inside the outdoor unit body 1.

[0066] The rotation of the three-stage speed increasing sprocket 803 drives the topmost roller sweep shaft 601 to rotate, and with the cooperation of the transmission structure 603, drives the remaining roller sweep shafts 601 to rotate synchronously, which is convenient for use.

[0067] The fourth-stage sprocket 805 rotates to drive the spiral auger 1002 to rotate in the sewage tank 1001. The rotation of the spiral auger 1002 is used to push the sewage and dirt in the sewage tank 1001, which is convenient to use.

[0068] In this embodiment, a chain tensioner 804 is rotatably mounted on one side outer wall of the T-shaped frame 501. The chain tensioner 804 is engaged with the chain 806 to tension the chain 806, ensuring that the chain 806 is in a tensioned state, thereby ensuring that stable and sufficient rotational power can be obtained between each sprocket.

[0069] In this embodiment, a sprocket transmission assembly 807 is further installed between the two fourth-stage sprockets 805 in the same Y-axis direction.

[0070] The sprocket transmission assembly 807 includes two transmission sprockets 8071 , which are coaxial and fixedly connected to two fourth-stage sprockets 805 in the same Y-axis direction. A transmission chain 8072 is sleeved on the two transmission sprockets 8071 .

[0071] The transmission chain 8072 is used to achieve transmission connection between the two transmission sprockets 8071, and then achieve transmission connection between the transmission modules 8 on the left and right sides of the hollow triangular air inlet box 2, so that one motor 9 can be used to drive the two sets of transmission modules 8 to work synchronously.

[0072] The motor 9 is fixedly mounted on the outdoor unit body 1 , and the power output end of the motor 9 is directly connected to the corresponding primary sprocket 802 through a coupling. The motor 9 starts to output rotational power to drive the primary sprocket 802 to rotate.

[0073] With this design, the motor 9 is started to drive the first-stage sprocket 802 to rotate. At this time, the first-stage sprocket 802 drives the second-stage speed-increasing sprocket 801, the third-stage speed-increasing sprocket 803, the fourth-stage sprocket 805 and the chain tensioner 804 to rotate through the chain 806. The chain tensioner 804 is used to tension the chain 806; the outer diameter of the first-stage sprocket 802 is larger than the outer diameter of the second-stage speed-increasing sprocket 801, the third-stage speed-increasing sprocket 803 and the fourth-stage sprocket 805, thereby enabling the second-stage speed-increasing sprocket 801, the third-stage speed-increasing sprocket 803 and the fourth-stage sprocket 805 to accelerate their rotation.

[0074] The secondary speed-increasing sprocket 801 rotates to drive the double-position centrifugal blower structure 7 to work; the tertiary speed-increasing sprocket 803 rotates and drives the in-line sweeping structure 6 to work through the cooperation of the transmission structure 603; the fourth-stage sprocket 805 rotates to drive the auger-type sewage discharge structure 10 to work; thereby realizing a larger range of power transmission and adapting to complex mechanical movement requirements, and the design of the sprocket can realize multi-point synchronous transmission, ensuring that the sweeping and sewage discharge operations can be coordinated and synchronized. Its durability and reliability are good, so that the entire mechanical system runs smoothly, reducing the failure rate, thereby ensuring the continuity and stability of the equipment.

[0075] In this embodiment, the two sets of transmission modules 8 are connected by a sprocket transmission assembly 807 to achieve synchronous transmission, thereby enabling the power output system to be streamlined to one motor 9. In addition, the chain 806 has good dust resistance, ensuring stable transmission operation in a dirty environment, and the failure rate is greatly reduced compared to the traditional multi-motor transmission system.

[0076] In this embodiment, the transmission module 8 can also be replaced by a belt transmission assembly. The first-stage sprocket 802, the second-stage speed-increasing sprocket 801, the third-stage speed-increasing sprocket 803 and the fourth-stage sprocket 805 are all replaced by pulleys, and the same transmission belt is provided on multiple pulleys. The transmission belt is used to ensure the synchronous transmission connection of multiple pulleys.

[0077] In this embodiment, if Figure 9 As shown, a spray pipe 11 with a control valve is installed on the left and right outer walls of the outdoor unit body 1. The spray pipe 11 is arranged along the length direction of the outdoor unit body 1. A plurality of spray heads 1101 are installed on the spray pipe 11. The spray heads 1101 are arranged toward the condenser 4. The spray pipe 11 and the spray heads 1101 are used to spray cleaning liquid directly onto the heat dissipation fins of the condenser 4.

[0078] The present invention also provides a method for operating an air-energy integrated machine that is easy to maintain. Based on the above-mentioned air-energy integrated machine that is easy to maintain, the method includes the following steps:

[0079] S101: First, ensure that the outdoor unit body 1 is powered off and in shutdown state, then continuously spray cleaning liquid onto the condensers 4 on the left and right sides through the external spray pipe. At the same time, start the motor 9 to work. The motor 9 synchronously drives the in-line sweeping structure 6, the auger-type sewage discharge structure 10 and the double-position centrifugal blowing structure 7 on the outer walls of the left and right sides of the hollow triangular air inlet box 2 through the transmission module 8 to work.

[0080] In this embodiment, the external spray pipe in step S101 can be a handheld spray hose by the staff, or a spray pipe 11 installed on the left and right outer walls of the outdoor unit body 1. The spray hose or spray pipe 11 is connected to the external spray liquid source, and the external spray liquid source outputs the spray liquid through the spray hose or spray pipe 11 for spraying operations.

[0081] In step S101, the motor 9 is started to drive the first-stage sprocket 802 to rotate. At this time, the first-stage sprocket 802 drives the second-stage speed-increasing sprocket 801, the third-stage speed-increasing sprocket 803, the fourth-stage sprocket 805 and the chain tensioner 804 to rotate through the chain 806. The chain tensioner 804 is used to tension the chain 806. The outer diameter of the first-stage sprocket 802 is larger than the outer diameter of the second-stage speed-increasing sprocket 801, the third-stage speed-increasing sprocket 803 and the fourth-stage sprocket 805, thereby enabling the second-stage speed-increasing sprocket 801, the third-stage speed-increasing sprocket 803 and the fourth-stage sprocket 805 to accelerate their rotation.

[0082] The secondary speed increasing sprocket 801 rotates to drive the double-position centrifugal blower structure 7 to work; the tertiary speed increasing sprocket 803 rotates and drives the inline roller sweeping structure 6 to work through the cooperation of the transmission structure 603; the quaternary sprocket 805 rotates to drive the auger type sewage discharge structure 10 to work.

[0083] S102: The in-line rolling sweep structure 6 rotates at high speed in close contact with the surface of the condenser 4, and the external spray pipe continuously sprays low-foam cleaning liquid evenly onto the condenser 4. Under the rotation of the in-line rolling sweep structure 6, the condenser 4 is deeply cleaned.

[0084] In step S102, the working principle of the in-line sweeping structure 6 is as follows: the three-stage speed increasing sprocket 803 rotates to drive the top sweeping shaft 601 to rotate, and with the cooperation of the transmission structure 603, drives the remaining sweeping shafts 601 to rotate synchronously. During the rotation, the sweeping shaft 601 drives the cleaning bristles 602 to rotate, so that the cleaning bristles 602 clean the heat exchange fins on the condenser 4. The mechanical rolling produces a continuous sweeping effect, which is used to deeply clean the condenser 4, including the slope corners and the roots of the heat exchange fins, to achieve full coverage cleaning operation, and thoroughly remove dust, impurities, dissolved shellac, grease and other sticky dirt on the heat exchange fins.

[0085] S103: The waste liquid mixed with dirt flows into the auger type sewage discharge structure 10 along the outer surface of the hollow triangular air inlet box 2. The auger type sewage discharge structure 10 works under the drive of the transmission module 8. The auger type sewage discharge structure 10 pushes the sewage and impurities to the sewage outlet, so that the sewage and impurities are discharged from the outdoor unit body 1. During the cleaning and maintenance process, the double-position centrifugal blowing structure 7 synchronously receives a part of the rotational power from the transmission module 8. The double-position centrifugal blowing structure 7 starts to generate high-speed airflow, which is used to cool the accessories inside the outdoor unit body 1.

[0086] In step S103, the working principle of the auger type sewage discharge structure 10 is: the fourth-stage sprocket 805 rotates to drive the spiral auger 1002 to rotate in the sewage tank 1001, and the rotation of the spiral auger 1002 is used to push the sewage and dirt in the sewage tank 1001, so that the sewage and dirt are discharged through the sewage pipe 1003.

[0087] In step S103, the working principle of the double-position centrifugal blower structure 7 is: the secondary speed-increasing sprocket 801 rotates to drive the centrifugal fan 703 to work; the centrifugal fan 703 generates high-speed airflow and is discharged through the exhaust port 702 on the air duct 701, thereby realizing air cooling and heat dissipation of the accessories inside the outdoor unit body 1, and keeping the outdoor unit body 1 at a normal working temperature.

[0088] S104: After completing the cleaning and maintenance work, the staff stops spraying and operates the in-line sweeping structure 6 and the double-position centrifugal blowing structure 7 for a period of time to dry the residual droplets and prevent rust, and then restarts the outdoor unit body 1.

[0089] Then check the status of the hollow triangular air inlet box 2 to confirm that the air inlet paths of the two axial flow fans 3 at the top of the hollow triangular air inlet box 2 are unobstructed. The design of the hollow triangular air inlet box 2 and the axial flow fans 3 is conducive to guiding the air into the condenser 4 and maintaining a good ventilation effect.

[0090] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
