Description

Technical Field

[0001] The present invention belongs to the technical field of heat pumps, and more specifically, particularly relates to an air source heat pump unit with a dust removal function. Background Art

[0002] A heat pump unit is a device that uses the reverse Carnot cycle principle to transfer heat from a low-temperature heat source to a high-temperature heat source by consuming a small amount of electrical energy. It is an efficient, energy-saving, and environmentally friendly energy utilization device. It generally includes the following structures: 1. Evaporator: The main function of the evaporator is to absorb heat from low-temperature heat sources (such as air, water, etc.).

[0003] 2. Compressor: The compressor is the core component of the heat pump unit. Its main function is to compress the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant.

[0004] 3. Condenser: The function of the condenser is to cool the high-temperature and high-pressure gaseous refrigerant, condense it into liquid, and release the heat absorbed in the evaporator and the heat generated by the work of the compressor.

[0005] 4. Expansion valve: The main function of the expansion valve is to throttle and reduce the pressure of the high-pressure liquid refrigerant coming out of the condenser.

[0006] The Chinese patent publication number is: CN116067040A, an air source heat pump unit, which is an assembled, modular module machine, which is conducive to reducing development resources, improving development efficiency, and shortening the development cycle.

[0007] The existing heat pump units have the following problems during actual operation: 1. The existing heat pump unit does not have a cleaning mechanism for the evaporator fins. Each time the fins are cleaned, the device must be disassembled on a large scale, resulting in low cleaning efficiency. For some places that operate continuously, long-term shutdown and disassembly cleaning will affect production progress or normal use needs. In addition, the disassembly and installation process usually requires high-intensity labor such as heavy object handling and delicate operations, which not only requires high physical strength of technicians, but also poses certain safety risks. 2. When the fins of the evaporator in the existing heat pump unit are disassembled and cleaned, frequent large-scale disassembly can easily cause damage to the equipment, and effective protective measures cannot be taken during cleaning, resulting in large-scale dust during cleaning. The cleaning process may also cause dust to escape to other parts of the heat pump unit, affecting the unit equipment and resulting in poor cleaning effect.

[0008] In view of this, the existing structure and defects are studied and improved, and an air source heat pump unit with dust removal function is provided, in order to achieve a more practical purpose. Summary of the invention

The number of the ash guide pipes is two, and the two ash guide pipes are fixedly installed on the side ends of the evaporation fixing frame. The dust collecting box is located at the side end of the lower fixing plate, and the C-shaped rod is slidably installed on the evaporation fixing frame. Two rectangular slide grooves are provided through the upper end of the evaporation fixing frame, and the two side ends of the evaporation fixing frame A side plate is fixedly installed, and two ash guide grooves are penetrated at one side end of the evaporation fixed frame. A switch button is provided at the upper end of the driving power supply, and a reciprocating screw rod is installed at the height of the output end of the first motor. An upper fixed plate is fixedly installed at the upper end of the evaporation fixed frame, and a first circular groove is penetrated at the side end of the upper fixed plate, and the end of the reciprocating screw rod is rotatably installed on the inner side wall of the first circular groove, and a second circular groove is penetrated at the side end of the lower fixed plate located on one side, and a second motor is fixedly installed at the side end of the lower fixed plate located on one side, and a threaded rod is fixedly installed at the output end of the second motor. The end of the rod is rotatably mounted on the inner side wall of the second circular groove, and a support plate is fixedly mounted on the side end of the lower fixed plate on one side, and two slide rails are provided on the upper end of the support plate, and two slide bars are fixedly mounted on the lower end of the dust collecting box, and the two slide bars are slidably mounted on the inner side walls of the slide rails respectively, and the circular frame is slidably mounted on the outer side end of the evaporation fixed frame, and an arc-shaped pressure block is fixedly mounted on the upper end of the circular frame, and two folded dustproof cloths are fixedly mounted between the circular frame and the two side plates, and a first threaded groove is penetrated through the side end of the circular frame, and the threaded rod is threadably rotatably mounted on the inner side wall of the first threaded groove.

[0011] Preferably, the C-shaped rod is slidably mounted on the inner side walls of two rectangular slide grooves, and a plurality of cleaning brushes are fixedly mounted on both side ends of the inner side walls of the C-shaped rod. The cleaning brushes on both sides are symmetrically distributed on the left and right, and the directions of the cleaning brushes on both sides are opposite.

[0012] Preferably, a second thread groove is formed through the side end portion of the C-shaped rod, and the reciprocating screw rod is threadably mounted on the inner side wall of the second thread groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing a circular frame and a folded dustproof cloth, before cleaning the fins in the evaporation fixed frame, the circular frame can be moved to drive the folded dustproof cloth to unfold, so as to shield and protect the cleaning area, avoid dust during cleaning, and make the working environment worse.

[0014] In the present invention, by providing a C-shaped rod and a cleaning brush in combination, when cleaning the fins on the evaporator, there is no need to manually clean the evaporator after disassembling it.

[0015] In the present invention, cleaning brushes are symmetrically arranged on both sides of the C-shaped rod. When the cleaning brushes on both sides move, each fin can be cleaned at the same time. It will take more time to clean one side of the fin separately and then clean the other side. However, cleaning both sides of the fin at the same time can complete the entire cleaning process at one time, which greatly shortens the cleaning time, ensures that all parts of the fin are fully cleaned, and improves the cleanliness.

[0016] In the present invention, by cooperating with a circular frame, an arc-shaped pressure block and a switch button, only after the circular frames on both sides drive the folded dust-proof cloth to move and fully unfold, can the arc-shaped pressure block press the switch button to start the first motor, and drive the cleaning brush on the C-shaped rod to clean, thereby providing a relatively stable cleaning environment for the cleaning brush, ensuring that in the process of cleaning the fins, the raised dust is effectively blocked within a certain range by the folded dust-proof cloth to prevent it from spreading to the surrounding environment.

[0017] In the present invention, by cooperating with the ash guide pipe and the dust collecting box, after the dust on the fins is cleaned, the dust on the fins can be centrally recovered without the need for subsequent secondary cleaning and collection, which simplifies the cleaning steps, further improves the efficiency of dust cleaning, and ensures short shutdown of the evaporator and continuous operation.

A plurality of equidistant fins 23 are fixedly mounted on the inner side wall of the evaporation fixed frame 21. The driving power source 3 is fixedly mounted on the upper end of the evaporation fixed frame 21. The side end of the driving power source 3 is electrically connected to the first motor 32. Two lower fixing plates 4 are fixedly mounted on the lower end of the evaporation fixed frame 21. There are two ash guide pipes 8. Both ash guide pipes 8 are fixedly mounted on the side ends of the evaporation fixed frame 21. When the cleaning brush 72 on the C-shaped rod 7 cleans the fins 23, the cleaning brush 72 drives the dust on the fins 23 to move to one side of the fins 23. The accumulated dust will enter the ash guide pipe 8 through the ash guide groove 25 under the push of the cleaning brush 72. The dust will enter the dust collecting box 6 along the ash guide pipe 8, thereby realizing the collection of dust. The dust box 6 is located at the side end of the lower fixed plate 4, and the C-shaped rod 7 is slidably installed on the evaporation fixed frame 21. The upper end of the evaporation fixed frame 21 is penetrated with two rectangular slide grooves 22, and the two side ends of the evaporation fixed frame 21 are fixedly installed with side plates 24. One side end of the evaporation fixed frame 21 is also penetrated with two ash guide grooves 25. The upper end of the driving power supply 3 is provided with a switch button 31, and the output end height of the first motor 32 is installed with a reciprocating screw rod 33. The upper end of the evaporation fixed frame 21 is fixedly installed with an upper fixed plate 34, and the side end of the upper fixed plate 34 is penetrated with a first circular groove 35, the end of the reciprocating screw rod 33 is rotatably mounted on the inner side wall of the first circular groove 35, and a second circular groove 41 is penetrated through the side end of the lower fixed plate 4 on one side, and a second motor 42 is fixedly mounted on the side end of the lower fixed plate 4 on one side. Before cleaning the fins 23 in the evaporator 2, the user can start the second motor 42 first. The second motor 42 in the present application is started by an infrared remote control device, and the infrared remote control device transmits instructions by emitting infrared signals of a specific frequency, and these signals can be received and decoded by a corresponding receiver, thereby realizing the control of the second motor 42; The output end of the second motor 42 is fixedly installed with a threaded rod 43, and the end of the threaded rod 43 is rotatably installed on the inner side wall of the second circular groove 41. A support plate 62 is fixedly installed on the side end of the lower fixed plate 4 on one side, and two slide rails 63 are provided on the upper end of the support plate 62.

The circular frame 5 is slidably installed on the outer end of the evaporation fixed frame 21, and an arc-shaped pressing block 51 is fixedly installed on the upper end of the circular frame 5. When the circular frame 5 moves to drive the folded dustproof cloth 52 to unfold, the circular frame 5 moves and simultaneously drives the arc-shaped pressing block 51 to move. When the arc-shaped pressing block 51 moves close to one side of the driving power source 3, the arc-shaped pressing block 51 contacts the switch button 31 and presses the switch button 31. When the circular frame 5 moves to drive the folded dustproof cloth 52 to be fully unfolded, the arc-shaped pressing block 51 presses the switch button 31 to start the first motor 32, and the start of the first motor 32 drives the reciprocating screw rod 33 to rotate; Two folding dustproof cloths 52 are fixedly installed between the circular frame 5 and the two side plates 24. A first thread groove 53 is penetrated through the side end of the circular frame 5. The threaded rod 43 is threadedly rotatably installed on the inner side wall of the first thread groove 53. When the second motor 42 is started, the threaded rod 43 is driven to rotate. The rotation of the threaded rod 43 drives the circular frame 5 to slide through the first thread groove 53. The sliding of the circular frame 5 drives the folding dustproof cloths 52 to unfold. When the folding dustproof cloths 52 are unfolded, they will cover and protect both sides of the fins 23 to avoid dust when cleaning later. When the circular frame 5 moves to the side close to the second motor 42 to drive the folding dustproof cloth 52 to fully unfold, the second motor 42 can be turned off. The C-shaped rod 7 is slidably installed on the inner side walls of the two rectangular slide grooves 22, and a plurality of cleaning brushes 72 are fixedly installed on the two side ends of the inner side walls of the C-shaped rod 7. The cleaning brushes 72 on both sides are symmetrically distributed on the left and right, and the directions of the cleaning brushes 72 on both sides are opposite. A second thread groove 71 is penetrated through the side ends of the C-shaped rod 7, and the reciprocating screw rod 33 is threadedly rotatably installed on the inner side wall of the second thread groove 71. The rotation of the reciprocating screw rod 33 will drive the C-shaped rod 7 to move through the second thread groove 71. Because the structural feature of the reciprocating screw rod 33 is that it has two thread grooves with the same pitch and opposite rotation direction, and the two ends are connected with a transition curve, so that the C-shaped rod 7 can realize reciprocating motion, and the movement of the C-shaped rod 7 will drive each cleaning brush 72 on the C-shaped rod 7 to move. When each cleaning brush 72 moves and contacts the fin 23, each cleaning brush 72 will scrape and clean the fin 23, thereby realizing the cleaning of the fin 23.

[0022] Working principle: In the first step, the fins 23 in the evaporator 2 of the heat pump rack 1 are likely to accumulate dust. When air flows through the fins 23 in the evaporator 2, dust and particles in the air will adhere to the surface of the fins 23 due to electrostatic adsorption, inertial collision, etc. The user can clean and collect the dust on the fins 23, and achieve efficient cleaning of the fins 23 while ensuring that the equipment is not disassembled on a large scale; In the second step, before cleaning the fins 23 in the evaporator 2, the user can start the second motor 42 first. The second motor 42 in the present application is started by an infrared remote control device. The infrared remote control device transmits instructions by emitting infrared signals of a specific frequency. These signals can be received and decoded by a corresponding receiver, thereby realizing control of the second motor 42. The start of the second motor 42 will drive the threaded rod 43 to rotate. The rotation of the threaded rod 43 will drive the circular frame 5 to slide through the first thread groove 53. The sliding of the circular frame 5 will drive the folded dustproof cloth 52 to unfold. The unfolding of the folded dustproof cloth 52 will cover and protect both sides of the fin 23 to avoid dust that may occur during later cleaning. When the circular frame 5 moves to the side close to the second motor 42 and drives the folded dustproof cloth 52 to fully unfold, the second motor 42 can be turned off; The device is provided with a circular frame 5 and a folded dustproof cloth 52 to cooperate. Before cleaning the fins 23 in the evaporation fixed frame 21, the circular frame 5 can be moved to drive the folded dustproof cloth 52 to unfold, so as to shield and protect the cleaning part, thereby avoiding dust during cleaning, making the working environment worse, and preventing dust from falling on surrounding equipment, pipes or other components to cause secondary pollution, thereby ensuring the effectiveness of dust cleaning; In the third step, when the circular frame 5 moves to drive the folded dustproof cloth 52 to unfold, the movement of the circular frame 5 will also drive the arc-shaped pressing block 51 to move. When the arc-shaped pressing block 51 moves close to the side of the driving power source 3, the arc-shaped pressing block 51 contacts the switch button 31 and presses the switch button 31. When the circular frame 5 moves to drive the folded dustproof cloth 52 to fully unfold, the arc-shaped pressing block 51 presses the switch button 31 to start the first motor 32. The start of the first motor 32 will drive the reciprocating screw 33 to rotate. The rotation of the reciprocating screw 33 will drive the C-shaped rod 7 to move through the second threaded groove 71. , because the reciprocating screw 33 has two thread grooves with the same pitch and opposite rotation direction, and the two ends are connected by a transition curve, when the arc-shaped pressing block 51 presses the switch button 31 to start the first motor 32 to drive the reciprocating screw 33 to rotate, the C-shaped rod 7 can realize reciprocating motion, thereby realizing the operation and reset of the C-shaped rod 7. The movement of the C-shaped rod 7 will drive each cleaning brush 72 on the C-shaped rod 7 to move. When each cleaning brush 72 moves and contacts the fin 23, each cleaning brush 72 will scrape and clean the fin 23, thereby realizing the cleaning of the fin 23; The device is provided with a C-shaped rod 7 and a cleaning brush 72, so that when cleaning the fins 23 on the evaporator 2, it is not necessary to manually clean the evaporator 2 after disassembling the evaporator 2. The disassembly of the evaporator 2 from shutdown, disassembly to subsequent installation and commissioning is relatively labor-intensive and material-intensive. The device can quickly complete the cleaning work through the cleaning brush 72 on the C-shaped rod 7, thereby reducing downtime and improving production efficiency. Moreover, it is not necessary to disassemble the evaporator 2, thereby reducing labor consumption. The device symmetrically arranges cleaning brushes 72 on both sides of the C-shaped rod 7. When the cleaning brushes 72 on both sides move, each fin 23 can be cleaned at the same time. It takes more time to clean one side of the fin 23 and then the other side. However, cleaning both sides of the fin 23 at the same time can complete the entire cleaning process at one time, which greatly shortens the cleaning time, ensures that all parts of the fin 23 are fully cleaned, and improves the cleanliness. The device cooperates with the circular frame 5, the arc-shaped pressing block 51 and the switch button 31. Only after the circular frames 5 on both sides drive the folded dust-proof cloth 52 to move and fully unfold, can the arc-shaped pressing block 51 press the switch button 31 to start the first motor 32, drive the cleaning brush 72 on the C-shaped rod 7 to clean, and provide a relatively stable cleaning environment for the cleaning brush 72, ensuring that in the process of cleaning the fins 23, the dust raised is effectively blocked within a certain range by the folded dust-proof cloth 52 to prevent it from spreading to the surrounding environment; In the fourth step, when the cleaning brush 72 on the C-shaped rod 7 cleans the fin 23, the cleaning brush 72 drives the dust on the fin 23 to move to one side of the fin 23, and the accumulated dust enters the ash guide pipe 8 through the ash guide groove 25 under the push of the cleaning brush 72, and the dust enters the dust collecting box 6 along the ash guide pipe 8, thereby realizing the collection of dust; The device is provided with an ash guide pipe 8 and a dust collecting box 6, and after cleaning the dust on the fins 23, the dust on the fins 23 can be collected in a centralized manner without the need for subsequent secondary cleaning and collection, thereby simplifying the cleaning steps, further improving the efficiency of dust cleaning, and ensuring short shutdown of the evaporator 2 and continuous operation.
