Description

Technical Field

[0001] The invention relates to the technical field of heat pump heaters, in particular to a heat pump heater based on rotary wheel dehumidification. Background Art

[0002] Air source heat pump heaters are widely used in household air-conditioning systems to control indoor temperature, heat cold water and provide hot water supply, but they do not have dehumidification function, and the humidity cannot meet the thermal comfort requirements of the human body; secondly, the existing rotary dehumidification mechanism dehumidifies by slowly rotating the dehumidification wheel. Specifically, the air to be dehumidified (air to be treated) is sucked in through the 3 / 4 area of ​​the windward side of the wheel. After passing through the wheel, the moisture in the air is absorbed or adsorbed by the hygroscopic material in the wheel. Subsequently, the dehumidified dry air is treated by other air treatment sections under the action of the fan and sent to the room or space to be dehumidified; at the same time At the same time, the other part of the air (regeneration air) is first heated by the air heater, and then passes through the rotor through the 1 / 4 area of ​​the windward side of the rotor to discharge the moisture absorbed by the rotor from the treated air. It can be seen that the rotor needs to contact the hot air and dehumidified air at the same time, and the sealing requirements of the regeneration area and the dehumidification area are high. The sealing strips set between the regeneration area and the dehumidification area are prone to fall off, which makes it easy for the hot air and the dehumidified air to mix, affecting the quality of the dehumidified air. At the same time, the hot air continues to act on the rotor, which will cause the temperature of the rotor to gradually increase, affecting the temperature of the dehumidified air, and it is not convenient to control the temperature of the exhaust air.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0018] Embodiment 1 like Figures 1 to 9As shown, a heat pump heater based on rotary dehumidification includes a component shell 1, a heat pump mechanism and a rotary dehumidification mechanism. The two ends of the component shell 1 are respectively provided with an air inlet window 16 and an air outlet window 17. A temperature control area and a dehumidification area are provided in the component shell 1. The temperature control area is located between the dehumidification area and the air outlet window 17. A control shell 42 is fixed in the temperature control area. A partition 2 is fixed in the control shell 42. The partition 2 divides the inner cavity of the control shell 42 into a cooling area 3 and a heating area 4 along a direction perpendicular to the air inlet direction. The heat pump mechanism includes a compressor 5, a condenser 6, an expansion valve 7, an evaporator 8 and a water storage tank 9. The condenser 6 is arranged in the water storage tank 9. The high-temperature port of the compressor 5 is connected to the air inlet port of the condenser 6 through a first pipe 10. The heating area A spiral heating pipe 11 is provided in zone 4, one end of the spiral heating pipe 11 is connected to the high-temperature port of the compressor 5 through an air inlet pipe 12, and the other end is connected to the air inlet port of the condenser 6 through an air outlet pipe. The air outlet port of the condenser 6 is connected to the air inlet port of the evaporator 8 through a circulation pipe 13. The expansion valve 7 is arranged on the circulation pipe 13, and the air outlet port of the steam pipe 8 is connected to the low-temperature port of the compressor 5 through a second pipe 14. A spiral cooling pipe 15 is provided in the cooling zone 3, one end of the spiral cooling pipe 15 is connected to the air outlet port of the evaporator 8, and the other end is connected to the low-temperature port of the compressor 5. A fresh air filter component is provided near the air inlet end of the component housing 1, and fresh air surface cooling and intermediate surface cooling are arranged in sequence between the fresh air filter component and the rotary dehumidification mechanism. The rotary dehumidification mechanism A rear surface cooler is arranged between the temperature control zone and the compressor 5, and the working medium in the evaporator 8 is compressed into a high-temperature, high-pressure gas. Part of the high-temperature, high-pressure gas enters the condenser 6 to heat the water in the water storage tank to provide hot water, and the other part of the high-temperature, high-pressure gas enters the spiral heating tube 15, and the spiral heating tube 15 exchanges heat with the air in the heating zone 4 to heat the air, and then the high-temperature, high-pressure gas in the spiral heating tube 15 converges into the condenser 6, so that the high-temperature, high-pressure gas is cooled into liquid, and then throttled and cooled by the expansion valve 7 to form a low-temperature gas again and enter the evaporator 8. Part of the low-temperature gas in the evaporator 8 is directly processed into a high-temperature, high-pressure gas by the compressor 5, and the other part of the low-temperature gas enters the spiral cooling tube 15 and cools the air in the cooling zone 3. The air inside is heat exchanged and finally processed into high-temperature and high-pressure gas by compressor 5. An air intake unit is arranged in the component shell 1, and the indoor air is sucked into the component shell 1 through the air intake unit. The indoor air is filtered by the fresh air filter component and then passes through the fresh air surface cooling, the middle surface cooling, and the dehumidification area in turn to enter the temperature control area. When the indoor temperature needs to be increased, the dehumidified air enters the heating area 4 and exchanges heat with the spiral heating tube 11, thereby exhausting the hot air to heat the indoor temperature; when the indoor temperature needs to be lowered, the dehumidified air enters the cooling area 3 and exchanges heat with the spiral cooling tube 15, thereby exhausting the low-temperature air to cool the indoor temperature. The cycle is repeated in this way, and the indoor air can be dehumidified while achieving temperature control.

[0019] Embodiment 2 In the traditional rotary dehumidification, dehumidification and regeneration are performed on the same rotary wheel, which easily causes gas mixing. At the same time, the sealing requirements at the critical position of dehumidification and regeneration are relatively high. Therefore, based on the first embodiment, as shown in FIG. Figures 1 to 4 As shown, the rotary dehumidification mechanism is arranged in the dehumidification zone, and the rotary dehumidification mechanism includes a fixed dehumidification shell 18, two groups of rotary dehumidification components arranged in the dehumidification shell 18, and a separation plate 19 is fixed in the dehumidification shell 18. The separation plate 19 separates the inner cavity of the dehumidification shell 18 into a regeneration zone and a rotary dehumidification zone from top to bottom. The rotary dehumidification component has the freedom to move along the height direction of the dehumidification shell 18. When one rotary dehumidification component is located in the regeneration zone, the other rotary dehumidification component is located in the rotary dehumidification zone. A regeneration fan unit 20 is arranged in the component shell 1, and the regeneration hot air port of the regeneration fan unit 20 is connected to the regeneration zone, so that the rotary dehumidification component has the freedom to move up and down, and the working state of the rotary dehumidification component is adjusted. One rotary dehumidification component is located in the rotary dehumidification zone to dehumidify the humid air, and the other rotary dehumidification component is located in the regeneration zone. In the regeneration zone, hot air is generated by the regeneration fan unit 20 to evaporate the moisture in the rotary dehumidification component, so that the rotary dehumidification component can continue to absorb moisture during regeneration. When the rotary dehumidification component in the rotary dehumidification zone reaches saturation, the rotary dehumidification component moves upward to the regeneration zone, and the other rotary dehumidification component moves downward to the rotary dehumidification zone to dehumidify the air. This is performed alternately, so that the regeneration action and the dehumidification action do not affect each other, and the sealing performance is significantly improved, and gas mixing will not occur. In specific implementation, when the two groups of rotary dehumidification components are switched in position, the rotary dehumidification component in the regeneration zone is first moved to the rotary dehumidification zone, and then the rotary dehumidification component in the rotary dehumidification zone is moved to the regeneration zone, so as to avoid the humid air entering the next stage without dehumidification when the position is switched, thereby ensuring that the dehumidification effect is not affected.

[0020] Embodiment 3 Based on the second embodiment, Figures 2 to 4As shown, a regeneration fan unit 20 is arranged in the component shell 1, and the regeneration hot air port of the regeneration fan unit 20 is connected to the regeneration zone. The rotary dehumidification component includes a rotary mounting plate 21, a dehumidification wheel 22 and a dehumidification motor 23. The separation plate 19 is penetrated with a rectangular groove 30 for the rotary mounting plate 21 to pass through. The rotary mounting plate 21 is penetrated with a mounting hole along the wind direction. The dehumidification wheel 22 is installed in the mounting hole. Since the traditional dehumidification wheel 22 needs to dehumidify and regenerate at the same time, the traditional dehumidification wheel 22 needs to be rotated so that dehumidification and regeneration are carried out alternately. The present invention is provided with two sets of rotary dehumidification components, so that the rotary dehumidification components in the rotary dehumidification zone are not regenerated during the dehumidification process. Therefore, the dehumidification wheel 22 is installed on the rotary mounting plate 21 without rotation. Each rotary dehumidification Each component is provided with a corresponding driving mechanism, which includes a motor 26, a main shaft 27 and a winding drum 28. The main shaft 27 is rotatably installed on the top of the component housing 1, and the winding drum 28 is fixedly mounted on the main shaft 27. The output shaft of the motor 26 is connected to the main shaft 27 through a coupling. A lifting wire 29 is wound on the winding drum 28. The lifting wire 29 passes through the component housing 1 and is connected to the top of the rotary wheel mounting plate 21. The motor 26 drives the main shaft 27 to rotate, and the main shaft 27 drives the winding drum 28 to rotate. Through the forward and reverse rotation of the motor 26, the winding drum 28 is wound around the lifting wire 29 to drive the rotary wheel mounting plate 21 to move upward to the regeneration area, or the winding drum 28 is lowered to release the lifting wire 29, so that the rotary wheel mounting plate 21 moves downward to the rotary wheel dehumidification area under the action of its own gravity, thereby realizing the position switching of the two sets of rotary wheel dehumidification components.

[0021] Embodiment 4 Since the dehumidification wheel 22 is heavy, relying on the self-locking support of the motor to support the weight of the dehumidification wheel assembly will shorten the service life of the motor 26. Therefore, based on the third embodiment, Figures 1 to 5As shown, since the main shaft 27 is equipped with a ratchet 31, a pawl seat 32 is fixed on the top of the component housing 1, and a pawl shaft 33 is rotatably connected to the pawl seat 32 through a torsion spring, and a pawl 34 is slidably equipped on the pawl shaft 33. The pawl 34 has the freedom to move axially along the pawl shaft 33, and a blocking shaft 35 is fixed on the component housing 1. When the pawl 34 is engaged in the ratchet groove of the ratchet 31, the pawl 34 contacts the top of the blocking shaft 35, and the reverse freedom of the main shaft 27 is limited by the cooperation between the pawl 34 and the ratchet 31. The reverse freedom of the main shaft 27 drives the rotating wheel mounting plate 21 to move downward, and a shoulder 36 is fixed on the pawl shaft 33, and an electromagnet 37 is equipped on the shoulder 36. One end of the pawl 34 close to the electromagnet 37 is fixed A permanent magnet 38 is fixed, and the electromagnet 37 is energized to generate a magnetic pole opposite to the permanent magnet 38. A spring 39 is sleeved on the pawl shaft 33, and the two ends of the spring 39 are respectively connected to the shaft shoulder 36 and the pawl 34. When the spring 39 is in a normal state, the pawl 34 is adapted to the ratchet groove of the ratchet wheel 31. When the motor 26 drives the winding disk 28 to wind the lifting wire 29, the rotary wheel mounting plate 21 will move upward. At this time, the ratchet wheel 31 squeezes the pawl 34 to deflect, and the pawl 34 drives the pawl shaft 33 to compress the torsion spring to deflect, so that the ratchet wheel 31 can rotate normally, so that the rotary dehumidification component can be smoothly moved to the regeneration area. When the rotary dehumidification component moves into place, the motor 26 stops, and the pawl shaft 33 is reset under the reaction force of the torsion spring, so that the ratchet wheel 31 can rotate normally. The pawl 34 engages the ratchet wheel 31. At this time, the rotary dehumidification component makes the winding drum 28 have a reverse movement tendency under the action of its own gravity, so that the ratchet wheel 31 presses down the pawl 34, and the pawl 34 is restricted by the shaft 35 to deflect downward, so that the pawl 34 is stably adapted in the ratchet groove of the ratchet wheel 31, thereby locking the reverse rotation state of the main shaft 27. The gravity of the rotary dehumidification component is supported by the cooperation of the ratchet wheel 31 and the pawl 34, which greatly reduces the force on the motor 26 and extends the service life of the motor 26. When it is necessary to rotate in the opposite direction to move the rotary dehumidification component into the rotary dehumidification area, the electromagnet 37 is energized to attract the permanent magnet 38, so that the permanent magnet 38 drives the pawl 34 to move close to the shaft shoulder 36, so that The pawl 34 is separated from the ratchet 31. At this time, the motor 26 drives the main shaft 27 to rotate in the opposite direction, so that the winding drum 28 slowly lowers the lifting line 29, so that the rotary dehumidification assembly moves into the rotary dehumidification area. When it is lowered into place, the motor 26 stops and the rotary dehumidification assembly is supported by the assembly housing 1; when the rotary dehumidification assembly needs to be lifted into the rotary dehumidification area, the electromagnet 37 is powered off, so that the pawl 34 returns to its original position under the reaction force of the spring 39, that is, the pawl 34 is re-adapted into the ratchet groove of the ratchet 31, and then the motor 26 drives the winding drum 28 to wind the lifting line 29 to move the rotary dehumidification assembly upward. After the rotary dehumidification assembly moves into place, the position of the rotary dehumidification assembly is locked by the cooperation of the pawl 34 and the ratchet 31.

[0022] Embodiment 5 Since the two sets of rotary dehumidification components need to be alternately positioned, in order to enable the two sets of rotary dehumidification components to automatically switch within a specified range, based on the fourth embodiment, further, as Figures 1 to 7 As shown, a pressure sensor 40 is embedded on the top surface of the ratchet 34. When the ratchet 34 contacts the stop shaft 35, the detection shaft of the pressure sensor 40 contacts the ratchet 31. A hollow sealing gasket 41 is fixed to the inner wall of the rectangular groove 30. The hollow sealing gasket 41 is fitted with the runner mounting plate 21 through its own compression deformation. An elastic sealing ring is provided around the runner mounting plate 21. The elastic sealing ring contacts the component housing 1 in a compressed state, thereby improving the sealing performance between the runner mounting plate 21 and the component housing 1 and eliminating the outer wall of the runner mounting plate 21 and the component housing 1. The gap between the inner walls and the setting of the elastic sealing ring will increase the weight of the entire wheel dehumidification assembly after the dehumidification wheel 22 absorbs moisture, and the wheel dehumidification assembly will further compress the elastic sealing ring. At this time, the wheel dehumidification assembly will have a tendency to continue to move downward, thereby increasing the pressure applied by the ratchet 31 on the pressure sensor 40, thereby automatically judging whether the dehumidification wheel 22 is fully absorbed by moisture through the pressure condition of the pressure sensor 40. When the detected pressure reaches the set pressure, the two groups of wheel dehumidification assemblies switch positions.

[0023] Embodiment 6 Since the dehumidified air needs to be heated or cooled to achieve temperature control, the cooling zone 3 and the heating zone 4 need to be operated separately, that is, when heating, the dehumidified air enters the heating zone 4, and the cooling zone 3 is in a closed state; when cooling, the dehumidified air enters the cooling zone 3, and the heating zone 4 is in a closed state. Therefore, based on the fifth embodiment, as shown in FIG. Figures 2 to 4As shown, a cooling window 43 is provided in the cooling zone 3 of the regulating shell 42 along the wind direction, and a heating window 44 is provided in the heating zone 4 along the wind direction. A cooling baffle 45 and a heating baffle 46 are respectively provided in the cooling window 43 and the heating window 44. The cooling baffle 45 and the heating baffle 46 both have the freedom to move along the height direction of the regulating shell 45. A cooling chute 47 is provided at the inner top of the cooling window 43, and a heating chute 48 is provided at the inner top of the heating window 44. The cooling chute 47 and the heating chute 48 both pass through the top of the regulating shell 42. The cooling baffle 45 and the heating baffle 46 are respectively slidably adapted in the cooling chute 47 and the heating chute 48. In the slide groove 48, the top of the cooling baffle 45 and the top of the heating baffle 46 are respectively fixed with a first rack 49 and a second rack 50, the first rack 49 and the second rack 50 are arranged opposite to each other, and a driving motor 51 is installed on the top of the component housing 1, and the output shaft of the driving motor 51 is connected with a driving gear 52, and a first gear 53 is rotatably arranged between the driving gear 52 and the first rack 49, and the first rack 49 and the driving gear 52 are both meshed with the first gear 53, and a second gear 54 is rotatably arranged between the driving gear 52 and the second rack 50, and the driving gear 52 and the second rack 50 are both meshed with the second gear 54, and the driving motor 51 drives the main shaft gear 52 to rotate, and the driving gear The wheel 52 drives the first rack 49 to move up and down through the first gear 53. At the same time, the driving gear 52 drives the second rack 50 to move up and down through the second gear 54. Since the first rack 49 and the second rack 50 are arranged opposite to each other and the number of gears used for transmission is the same (that is, the number of the first gear 53 is the same as the number of the second gear 54), the movement directions of the first rack 49 and the second rack 50 are opposite. That is, when the first rack 49 drives the cooling baffle 45 to move upward to open the cooling window 43, the second rack 50 drives the heating baffle 46 to move downward to close the heating window 44. Similarly, the first rack 49 drives the cooling baffle 45 to move downward to close the cooling window When the temperature rise window 43 is closed, the second rack 50 drives the heating baffle 46 to move upward to open the heating window 44, so that the cooling window 43 and the heating window 44 can be independently connected through a driving motor 51, thereby realizing precise temperature control; secondly, the first gear 53 and the second gear 54 are arranged to extend the transmission distance. In actual situations, the number of the first gears 53 is selected according to the distance from the driving gear 52, so that the driving gear 52 can smoothly drive the first rack 49 to move through multiple first gears 53, and ensuring that the number of the first gears 53 is the same as the number of the second gears 54 can make the cooling baffle 45 and the heating baffle 46 move in opposite directions.

[0024] Embodiment 7 On the basis of Example 6, Figure 2 , Figure 8 and Fig. 9As shown, the fresh air filter assembly includes a front hollow plate 55 and a rear hollow plate 56, and one end of the front hollow plate 55 close to the rear hollow plate 56 is connected to a plurality of first filter threads 57, and one end of the rear hollow plate 56 close to the front hollow plate 55 is connected to a plurality of second filter threads 58, and the second filter threads 58 are perpendicular to the first filter threads 57. The front hollow plate 55 and the rear hollow plate 56 are connected together by screws to make the first filter threads 57 contact the second filter threads 58 to form a filter net. A hollow mounting plate 59 is fixed in the assembly shell 1, and the rear hollow plate 56 is connected to the hollow mounting plate 59 by mounting screws. The air sucked into the assembly shell 1 will first be filtered by the fresh air filter assembly to eliminate particles and dust in the air and improve the air quality. Therefore, the filter net of the fresh air filter assembly needs to be cleaned or replaced after a period of use. At present, the filter net formed by the fresh air filter assembly is an integral structure. When it is blocked When the problem is serious or difficult to clean, the entire filter needs to be replaced, and the subsequent maintenance cost is high. For this reason, the fresh air filter assembly is designed as a detachable front hollow plate 55 and rear hollow plate 56, and the filter screen is designed as a split structure, that is, the first filter wire 57 and the second filter wire 58 are in contact to form a filter screen. When the fresh air filter assembly needs to be cleaned, the fresh air filter assembly is first removed from the hollow mounting plate 59, and then the front hollow plate 55 and the rear hollow plate 56 are removed and separated to separate the first filter wire 57 and the second filter wire 58, thereby quickly cleaning and unblocking impurities blocked in the mesh of the filter screen. At the same time, after the first filter wire 57 and the second filter wire 58 are separated, the first filter wire 57 and the second filter wire 58 will not block each other and affect cleaning, thereby facilitating the unblocking and cleaning of the fresh air filter assembly, extending the replacement cycle of the fresh air filter assembly, reducing the subsequent maintenance cost, and reducing the labor intensity of cleaning.

[0025] Embodiment 8 Dust and impurities may get stuck between two adjacent first filter threads 57 or between two adjacent second filter threads 58. At this time, the first filter thread 57 and the second filter thread 58 cannot be quickly cleared after being separated. Therefore, based on the seventh embodiment, Figure 8 and Fig. 9As shown, an adjustment cavity 60 is provided in the front hollow plate 55, and an adjustment block 61 is slidably provided in the adjustment cavity 60. The adjustment block 61 moves along the length direction of the first filter wire 57. One end of the first filter wire 57 is connected to the front hollow plate 55, and the other end penetrates into the adjustment cavity 60 to connect to the adjustment block 61. A wedge-shaped surface 62 is provided at the center end of the adjustment block 61 close to the front hollow plate 55. The wedge-shaped surface 62 is matched with a wedge-shaped block 63. The wedge-shaped block 63 is threaded with a screw 64. The screw 64 is rotatably connected to the front hollow plate 55. An operating groove 65 is provided on one side of the front hollow plate 55. One end of the screw 64 extends into the operating groove 65. The screw 64 is located in the operating groove 65. One end is provided with a hexagonal groove, and the end of the adjustment block 61 away from the wedge block 23 is connected to the adjustment spring 66, and the other end of the adjustment spring 66 is connected to the front hollow plate 55. After the front hollow plate 55 and the rear hollow plate 56 are disassembled, the front hollow plate 55 and the rear hollow plate 56 are cleared one by one. Specifically, the operation groove 65 provides an operation space, and a tool is used to drive the screw 64 to rotate. Since the wedge block 63 cooperates with the wedge surface 62 of the adjustment block 61, and the adjustment block 61 is slidably arranged in the adjustment cavity 60, the rotational freedom of the wedge block 63 is limited, so that the wedge block 63 makes a linear motion along the axial direction of the screw 64, so that the wedge block 63 moves along the inclined direction of the wedge surface 62 When the wedge-shaped block 63 pushes the adjusting block 61 to move close to the adjusting spring 66, the adjusting spring 66 is compressed, and the adjusting block 61 tightens the first filter thread 57. At this time, the first filter thread 57 is in vertical contact with the tightened second filter thread 58 to form a filter screen. When dredging, the high end of the wedge-shaped block 63 moves close to the high end of the wedge-shaped surface 62, so that the adjusting block 61 is always in contact with the wedge-shaped block 53 under the force of the adjusting spring 66, so that the adjusting block 61 moves close to the center of the front hollow plate 55, so that the first filter thread 57 is in a relaxed state. At this time, the front hollow plate 55 is shaken to dredge the impurities stuck between the first filter threads 57. The air filter 57 is unblocked by the air filter 52, and the air filter 58 is unblocked by the air filter 52. After the unblocking is completed, the high end of the wedge block 63 moves close to the low end of the wedge surface 62, so that the wedge block 63 pushes the adjustment block 61 to move away from the center of the front hollow plate 55, so that the first filter wire 57 is in a taut state again; the structure of the rear hollow plate 56 is the same as that of the front hollow plate 55, and the rear hollow plate 56 adopts the same structure and the same method for dredging. After the unblocking is completed, the second filter wire 58 is in a taut state again, and then the front hollow plate 55 and the rear hollow plate 56 are installed together, and finally installed on the hollow mounting plate 59 to complete the maintenance operation of the fresh air filter assembly.
