Description

Technical Field

[0001] This utility model relates to the technical field of heat pump hot air devices, and in particular to a heat pump hot air device with waste heat recovery and utilization. Background Technology

[0002] A heat pump hot air device with waste heat recovery and utilization is composed of conventional heat pump components such as compressor, evaporator, and condenser. When working, the compressor compresses the refrigerant, the condenser generates hot air, and the evaporator transfers heat. The heat is then transferred to the medium to be heated through heat exchangers or stored in a heat storage device, thereby improving energy utilization and reducing waste.

[0003] In the existing technology, the existing device includes: a housing, a condenser tube, an evaporator tube, a compressor, a water inlet pipe, a water outlet pipe, and a fan. One side of the water inlet pipe and the water outlet pipe are fixedly connected to one side of the condenser tube and the evaporator tube, respectively. The evaporator tube is fixedly connected to one side of the condenser tube. The condenser tube and the evaporator tube are installed inside the housing. The fan is installed on one side of the evaporator tube. Other substances carrying waste heat are introduced into the condenser tube through the water inlet pipe. The coolant in the condenser tube absorbs the heat from these substances and is then introduced into the evaporator tube by the fan. The coolant releases heat in the evaporator tube, heating the surrounding air. This heated air is then blown out by the fan, forming hot air. In use, this device utilizes the waste heat of other substances, absorbing the waste heat and converting it into hot air. Although this method improves energy efficiency, it requires drawing in cold air from the outside during hot air heating. The cold air exchanges heat with the evaporator inside the device, raising its temperature. However, the temperature inside the device remains low. If the hot air is not expelled from the device in time, it will condense on the inner wall of the shell, forming condensate. Since the heat exchange is continuous, condensate will continuously form on the inner wall of the shell. This condensate will slide down the inner wall to the bottom of the device. If this condensate is not cleaned in time, it may corrode the inside of the device, causing damage. Furthermore, excessive condensate may lead to poor heat exchange efficiency and incomplete waste heat recovery.

[0004] Therefore, it is necessary to provide a new heat pump hot air device with waste heat recovery and utilization to solve the above-mentioned technical problems. Utility Model Content

[0013] Compared with related technologies, the heat pump hot air device with waste heat recovery and utilization provided by this utility model has the following beneficial effects:

[0014] In practical use, when the heat pump hot air device is in operation, the outside cold air undergoes heat exchange to form hot air, which then comes into contact with the inner wall of the heat pump hot air device, forming condensate. At this time, the condensate slides from the inner wall of the device onto the water collection plate. The drive component drives the cleaning rod to reciprocate linearly, sweeping the condensate on the water collection plate to the water outlets on both sides of the heat pump hot air device. The condensate is then collected by the water collection frame. During the reciprocating motion, the cleaning rod is in close contact with the inner wall of the heat pump hot air device, which not only removes the condensate on the water collection plate but also removes the condensate on the inner wall of the heat pump hot air device. This allows for the rapid removal of condensate inside the device, preventing excessive condensation from damaging the device. Furthermore, timely handling of condensate allows for faster and more efficient heat exchange between the cold air and the heat pump hot air device, resulting in more thorough waste heat recovery and utilization.

[0022] In the specific implementation process, such as Figures 1-4 As shown, the present invention provides a heat pump hot air device with waste heat recovery and utilization, including: a heat pump hot air device body and a water purification device, wherein the water purification device is installed inside the heat pump hot air device.

[0023] The water purification device includes: a water receiving plate 1, a cleaning rod 2, and a drive assembly. The outer side of the water receiving plate 1 is fixedly connected to the inner wall of the heat pump hot air device body. The heat pump hot air device body has water outlet holes 3 on both sides near the water receiving plate 1. A fixing block 4 is provided at the water outlet hole 3. A water receiving frame 5 is movably provided on the outer side of each water outlet hole 3. Three sliding grooves 6 are provided on the water receiving plate 1. Three sliding blocks 7 are provided on one side of the cleaning rod 2. The three sliding blocks 7 extend into the three sliding grooves 6 respectively. One side of the drive assembly passes through one of the sliding blocks 7. The drive assembly is rotatably connected to the fixing block 4. One side of the drive assembly is fixedly connected to one side of the heat pump hot air device body, and both ends of the drive assembly are located inside the two water receiving frames 5. The cleaning rod 2 is L-shaped. The outer wall of the cleaning rod 2 is in contact with the inner wall of the heat pump hot air device body. The cross-sections of the three sliding grooves 6 are cross-shaped. The cross-sections of the three sliding blocks 7 are cross-shaped. The outer walls of the three sliding blocks 7 are in contact with the inner walls of the three sliding grooves 6 respectively.

[0024] It should be noted that the outer wall of the aforementioned water-receiving plate 1 is fixedly connected to the inner wall of the heat pump hot air device body, so that the water-receiving plate 1 can collect all the condensate generated inside the heat pump hot air device body. The aforementioned drive assembly drives the cleaning rod 2 to reciprocate on the water-receiving plate 1. The outer side of the cleaning rod 2 is in contact with the outer side of the water-receiving plate 1, so that the cleaning rod 2 can remove the condensate collected on the outer side of the water-receiving plate 1. During the reciprocating motion, the cleaning rod 2 sweeps the condensate collected on the surface of the water-receiving plate 1 to the water outlet 3 on both sides of the heat pump hot air device body, and then collects it through the water receiving frame 5. The condensate is collected, and the water collection frame 5 is a movable connection. The water collection frame 5 is movably connected to the outside of the heat pump hot air device body by bolts. In actual use, the water collection frame 5 can be removed and the internal condensate can be disposed of for convenient use next time. The cleaning rod 2 is L-shaped, which allows the cleaning rod 2 to not only remove the condensate on the water receiving plate 1, but also to directly clean one side of the inner wall of the heat pump hot air device body, making the cleaning effect better. The aforementioned sliding groove 6 and sliding block 7 make the cleaning rod 2 move more smoothly on the water receiving plate 1 and the movement process more stable.

[0025] The drive assembly includes a drive motor 8, a reciprocating screw 9, and a drive gear set. One side of the reciprocating screw 9 passes through one of the three sliding blocks 7, and the reciprocating screw 9 is threadedly connected to the sliding block 7. One end of the reciprocating screw 9 passes through a fixed block 4, and the reciprocating screw 9 is rotatably connected to the fixed block 4. One side of the drive gear set is fixedly connected to one side of the reciprocating screw 9. The drive gear set is located inside the water receiving frame 5. The other side of the drive gear set is fixedly connected to the output end of the drive motor 8. One side of the drive motor 8 is fixedly connected to the outside of the heat pump hot air device body. The drive gear set includes a first bevel gear 10 and a second bevel gear 11. One side of the first bevel gear 10 is fixedly connected to one side of the reciprocating screw 9. The second bevel gear 11 meshes with the first bevel gear 10. The side of the second bevel gear 11 away from the first bevel gear 10 is fixedly connected to the output end of the drive motor 8.

[0026] It should be noted that the aforementioned drive motor 8 drives the second bevel gear 11 to rotate synchronously, and the second bevel gear 11 drives the first bevel gear 10 and the reciprocating screw 9 to rotate, so that the reciprocating screw 9 drives the cleaning rod 2 to reciprocate linearly along the reciprocating screw. Moreover, the aforementioned reciprocating screw 9 is rotatably connected to the fixed block 4, making the installation of the reciprocating screw 9 more stable.

[0027] The heat pump hot air device body includes: a housing 12, a condenser pipe 13, an evaporator pipe 14, a baffle plate 15, a fan 16, and a compressor 17. The condenser pipe 13 is fixedly connected to one side of the evaporator pipe 14. Both the evaporator pipe 14 and the condenser pipe 13 are fixedly installed inside the housing 12. An air inlet 18 and an air outlet 19 are respectively provided on both sides of the housing 12. The compressor 17 is fixedly installed between the condenser pipe 13 and the evaporator pipe 14. A water outlet 21 is provided on one side of the evaporator pipe 14, and a water inlet 20 is provided on one side of the condenser pipe 13.

The fan 16 is fixedly installed inside the baffle plate 15, and the position of the fan 16 corresponds to that of the evaporator pipe 14.

[0028] It should be noted that, in use, the above-mentioned device introduces liquid with residual heat through the inlet pipe 20. When the liquid moves to the condenser pipe 13, the coolant inside the condenser pipe 13 absorbs the heat of the liquid. The compressor 17 converts the coolant into a high-temperature, high-pressure gas and flows into the evaporator pipe 14. At this time, the coolant releases heat in the evaporator pipe 14. The device then absorbs cold air from the outside through the air inlet 18 on one side of the casing and blows the cold air to the evaporator pipe 14 through the fan 16. The cold air from the outside exchanges heat with the heat released by the evaporator pipe, turning the cold air into a heat outlet and discharging it from the air outlet pipe 19. The liquid with residual heat then exchanges heat with the coolant and is discharged from the outlet pipe 21. At this time, the device completes one cycle, recovering and utilizing the residual heat in the liquid and turning it into hot air that is blown out from inside the device, thus enabling the device to recover and utilize residual heat.
