Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to a multi-purpose air conditioner with an energy recovery device. Background Art

[0002] Common air conditioners in life are mainly used to adjust the indoor temperature to provide a comfortable indoor environment. When the traditional air conditioner outdoor unit operates, it will generate a large amount of heat, which is usually discharged into the air in the form of waste heat, causing great energy loss and not conforming to the current concept of energy conservation and emission reduction; therefore, the heat energy generated by the air conditioner can be recycled, such as preheating domestic and commercial hot water or recovering the waste heat into the room to assist in heating, so as to make full use of energy and reduce energy waste.

[0003] With the development of technology, technicians in related fields have also carried out corresponding optimizations on the heat recovery of air conditioners. For more accurate comparison, for example, Chinese Patent No. CN114484835A discloses an energy recovery system for a central air conditioner, including a housing, an air conditioner main body disposed in the housing, and an energy recovery mechanism disposed on the air conditioner main body. The energy recovery mechanism includes an energy recovery component and a heat conduction component disposed on the air conditioner main body through a fixing component. The fixing component includes four recovery plates that are mutually clamped and surround the air conditioner main body.

[0004] When the above-mentioned prior art is in use, the energy recovery component is used to dissipate heat from the air conditioner main body, and the heat generated during the operation of the air conditioner main body can also be absorbed, avoiding energy waste, and then conducted to the outside of the housing through the heat conduction component for recycling.

[0005] However, there are still some deficiencies in the above-mentioned prior art in the process of recovering the heat of the air conditioner: 1. Since the compressor and condenser in the air conditioner outdoor unit generate a large amount of heat in the cooling mode, the heat inside the air conditioner main body needs to be discharged in time. However, the above-mentioned prior art uses recovery plates to surround the air conditioner main body, which is not conducive to the heat dissipation of the internal equipment of the air conditioner main body, and is likely to cause poor heat dissipation inside the air conditioner main body, resulting in poor cooling effect, increased power consumption, and compressor overload and other adverse phenomena, thus affecting the use effect.

[0006] 2. Also, when the air conditioner is in the heating mode, the evaporator in the air conditioner outdoor unit is prone to cooling and frosting. However, the above-mentioned prior art can only be used for heat dissipation and cannot recycle the heat for defrosting the evaporator. Moreover, using the recovery plates is likely to cause poor ventilation of the air conditioner main body, resulting in the retention of hot air, and the heat cannot be discharged in time when the evaporator is defrosted, which is likely to affect the defrosting speed and cause incomplete defrosting, further affecting the use effect.

[0007] Therefore, under the viewpoints stated above, there is still room for improvement in the existing air-conditioning heat recovery means. Summary of the Invention

[0013] As a preferred technical solution of the present invention, a support pipe is arranged on one side of the first heat dissipation pipe close to the second heat dissipation pipe.

Two mutually meshing transmission gears are sleeved on the outer walls of the linkage shaft and the positioning shaft along the axial direction. A driving shaft is installed on the transmission shaft of the cooling fan. A belt is jointly sleeved between the driving shaft and the linkage shaft.

[0015] As a preferred technical solution of the present invention, a steering shaft is rotatably installed on the support bracket, and two idler wheels meshing with the transmission gears on the outer wall of the positioning shaft are sleeved on the outer wall of the steering shaft, and the idler wheels can mesh with the transmission gears on the outer wall of the linkage shaft.

[0016] As a preferred technical solution of the present invention, a sliding groove is formed on the support bracket, the linkage shaft is slidably butted in the sliding groove, an auxiliary bracket is rotatably sleeved on the linkage shaft, and a cylinder is installed on the support bracket through a support frame, and the telescopic end of the cylinder is connected to the auxiliary bracket.

[0019] In summary, the present application includes the following beneficial technical effects: First, in the present invention, the water source in the water tank circulates in the circulation pipeline, and the water in the circulation pipeline sequentially absorbs the heat of the condenser and the compressor. Therefore, the water in the circulation pipeline is heated and then flows back into the water tank and is discharged through the water outlet pipe for use. Moreover, the present invention can be used alone as a water heater in both the air-conditioning cooling mode and the heating mode throughout the year. After the heated water is discharged, it can be used for domestic and commercial water, etc. In this way, the heat in the outdoor unit is recovered and fully utilized, which can effectively reduce energy waste, reduce heat emissions, and can also reduce the working environment temperature of the internal equipment in the outdoor unit, prolonging the equipment life.

[0020] Second, when the air-conditioning indoor unit is in the cooling mode, the present invention can further cool down the compressor and the condenser by absorbing heat with the water in the circulation pipeline on the basis of the heat dissipation of the condenser by the cooling fan, avoiding poor cooling effect, increased power consumption, compressor overload and other adverse phenomena caused by poor heat dissipation.

[0021] Third, when the air-conditioning indoor unit is in the heating mode, the present invention can make the water in the circulation pipeline circulate in the reverse direction, so that the hot water absorbing the heat on the surface of the compressor passes through the evaporator, thereby defrosting the evaporator with the hot water to facilitate accelerating the defrosting speed in cooperation with the air conditioner.

When the present invention is in the air - conditioning refrigeration mode, the impeller is controlled to rotate forward, and the impeller controls the water in the circulating pipeline to flow back from the water tank through the first radiating pipe and the second radiating pipe in sequence, so as to cool the condenser and the compressor; when the air - conditioning is in the heating mode, the impeller is controlled to rotate in reverse, and the impeller controls the water in the circulating pipeline to circulate in the reverse direction, so that the evaporator can be defrosted after the water absorbs the heat of the compressor, without adjusting the water supply and drainage pipelines of the water inlet pipe and the water outlet pipe, and thus the operation is more convenient.

[0023] V. When the hot water in the water tank is needed in the present invention, the hot water in the drainage area can be discharged through the water outlet pipe for use; when the air - conditioner is in the on state and hot water is not needed, the hot water in the water inlet area and the drainage area gradually becomes saturated, so that the water supply pipe cannot continue to supply water. Therefore, under the action of the impeller, the hot water in the drainage area can flow into the water inlet area, and then passes through the water inlet area, the circulating pipeline and the drainage area in sequence to form an internal circulation, so as to always maintain the heat dissipation and defrosting of the internal equipment of the air - conditioner and improve the service performance.

Specific embodiments

[0037] The following will be described in detail with reference to the appended Figure 1-11 embodiments of the present invention.

[0038] The embodiment of the present application discloses a multi-purpose air conditioner with an energy recovery device. It should be noted that the multi-purpose air conditioner with an energy recovery device of the present application is mainly applied to the process of heat recovery and utilization inside the air conditioner outdoor unit. In terms of technical effects, the water in the circulation pipeline can sequentially absorb the heat of the condenser 3 and the compressor 2, so that the water in the circulation pipeline is heated and then flows back into the water tank 8 and is discharged through the water outlet pipe 83 for use. Moreover, it can be used as a water heater alone in both the air conditioning cooling mode and the heating mode throughout the year. The heated water can be used for domestic and commercial water, etc. Especially when the water in the circulation pipeline circulates, when the air conditioner indoor unit is in the cooling mode, the water in the circulation pipeline can absorb heat to cool down the compressor 2 and the condenser 3. And when the air conditioner indoor unit is in the heating mode, the water in the circulation pipeline is controlled to circulate in the reverse direction, so that the hot water that absorbs the heat on the surface of the compressor 2 passes through the evaporator 4 and defrosts it. Further, when the air conditioner of the present application is in the on state and hot water is not needed, the water in the circulation pipeline can form an internal circulation, so as to always maintain the heat dissipation and defrosting of the internal equipment of the air conditioner and improve the service performance.

[0039] Refer to Figure 1 , Figure 2 andFigure 3 As shown, a multi-purpose air conditioner with an energy recovery device includes an outdoor unit casing 1, a partition 11 is installed inside the outdoor unit casing 1, and is used to separate the interior of the outdoor unit casing into a compression chamber 12 and a condensation chamber 13, a compressor 2 is installed in the compression chamber 12, and the compressor 2 consists of a liquid storage cylinder and a cylinder body, and the upper ends of the liquid storage cylinder and the cylinder body are respectively connected to an intake pipe 21 and an exhaust pipe 22, a condenser 3, an evaporator 4 and a heat dissipation fan 5 are arranged in the condensation chamber 13, a first heat dissipation pipe 6 is commonly installed on the outer walls of the condenser 3 and the evaporator 4, a second heat dissipation pipe 7 is wound on the outer wall of the compressor 2, a water tank 8 connected to the first heat dissipation pipe 6 and the second heat dissipation pipe 7 is arranged on the top wall of the condensation chamber 13, and the first heat dissipation pipe 6 and the second heat dissipation pipe 7 are connected at one end away from the water tank 8, and a circulation channel for absorbing heat from the internal equipment of the air conditioner is formed by the first heat dissipation pipe 6, the second heat dissipation pipe 7 and the water tank 8.

[0040] It should be noted that since the exhaust pipe 22 of the compressor 2 discharges high-temperature gas, the exhaust pipe 22 of the compressor 2 also has heat. Therefore, the first heat dissipation pipe 6 in this embodiment is wound around the liquid storage cylinder, the cylinder body and the outer wall of the exhaust pipe 22; in addition, in order to improve the heat absorption efficiency, the first heat dissipation pipe 6 and the second heat dissipation pipe 7 are preferably copper tubes with strong thermal conductivity.

[0041] Furthermore, in this embodiment, a water inlet pipe 82 and a water outlet pipe 83 connected thereto are installed at the upper end of the water tank 8. The water inlet pipe 82 is used to connect to an external water supply pipeline, and the water outlet pipe 83 is used to discharge the water in the water tank 8 for use.

[0042] It should be noted that a baffle 81 is installed on the inner wall of the water tank 8 to separate the water tank 8 into a water inlet area and a water outlet area. The water inlet area is connected to the first heat dissipation pipe 6 and the water inlet pipe 82, and the water outlet area is connected to the second heat dissipation pipe 7 and the water outlet pipe 83.

[0043] In the specific implementation process, the external water supply pipeline supplies water to the water tank 8 through the water inlet pipe 82, and the water passes through the water inlet area, the first heat dissipation pipe 6, the second heat dissipation pipe 7 and the drainage area in sequence, and finally is discharged through the water outlet pipe 83 (at Figure 3 As shown in the figure, the water source circulates in the circulation pipe, and the water in the circulation pipe absorbs the heat of the condenser 3 and the compressor 2 in turn, so that the water in the circulation pipe flows back to the water tank 8 after being heated and is discharged through the outlet pipe 83 for use, so that the hot water is used for domestic and commercial water, etc., thereby recovering the heat in the outdoor unit and making full use of it, which can effectively reduce energy waste, reduce heat emissions, and can lower the temperature of the working environment of the internal equipment of the outdoor unit, thereby extending the life of the equipment.

[0044] In hot summer weather, the indoor unit of the air conditioner operates in the cooling mode. The compressor 2 in the outdoor unit generates heat, and the refrigerant gas in the compressor 2 releases heat and liquefies in the condenser 3, resulting in a relatively high surface temperature of the condenser 3. Therefore, the present invention can further cool down the compressor 2 and the condenser 3 by absorbing heat with the water in the circulating pipeline on the basis of the heat dissipation of the condenser 3 by the cooling fan 5, avoiding adverse phenomena such as poor cooling effect, increased power consumption, and overload of the compressor 2 caused by poor heat dissipation.

[0045] In cold winter weather, the indoor unit of the air conditioner operates in the heating mode. The refrigerant absorbs heat and evaporates inside the evaporator 4, resulting in a relatively low surface temperature of the evaporator 4, which is prone to frosting. At this time, the water supply pipeline is connected to the water outlet pipe 83, and the water inlet pipe 82 is used to drain the water in the water tank 8, so that the water in the circulating pipeline can circulate in the reverse direction, and the hot water that absorbs the heat on the surface of the compressor 2 passes through the evaporator 4, thereby defrosting the evaporator 4 with the hot water to facilitate accelerating the defrosting speed in cooperation with the air conditioner.

[0046] In summary, the present invention can be used alone as a water heater in both the cooling mode and the heating mode of the air conditioner throughout the year. In addition, in winter, the heated water can be used for indoor auxiliary heating; after the heated water is discharged, it can be used for domestic water, such as bathing, clothes washing, etc., or commercial water, such as equipment cleaning, hotel guest room service, and barbershop water, etc.

[0047] Refer to Figure 4 and Figure 5 As shown, in order to improve the heat dissipation and defrosting efficiency of the compressor 2, the condenser 3, and the evaporator 4, in this embodiment, a heat conducting sheet 64 is provided between the first heat dissipation pipe 6 and the condenser 3 and the evaporator 4. The contact surfaces of the heat conducting sheet 64 with the condenser 3 and the evaporator 4 are coated with heat conducting silicone grease, and the contact surface of the second heat dissipation pipe 7 with the compressor 2 is also coated with heat conducting silicone grease to increase the heat absorption efficiency.

[0048] Refer to Figure 6 、 Figure 7 and Figure 9 As shown, in order to be able to adjust the forward and reverse circulation of the water in the circulating pipeline according to the heating mode and the cooling mode of the air conditioner, in this embodiment, the water source circulation direction in the circulating pipeline can be automatically adjusted. Specifically, a support pipe 61 is provided on one side of the first heat dissipation pipe 6 close to the second heat dissipation pipe 7. The first heat dissipation pipe 6, the second heat dissipation pipe 7, and the support pipe 61 are connected and communicated. A rotating shaft 612 is rotatably installed inside the support pipe 61 through a fixing frame 611, and two impellers 613 are symmetrically sleeved on the outer wall of the rotating shaft 612 along the axial direction.

[0049] Further, in this embodiment, a supporting bracket 62 is installed on the side wall of the partition plate 11 above the support pipe 61. A positioning shaft 621 parallel to the rotating shaft 612 is rotatably installed on the supporting bracket 62. The positioning shaft 621 and the rotating shaft 612 are connected by a belt drive. A linkage shaft 622 is also rotatably arranged on the supporting bracket 62. Two mutually meshing transmission gears 623 are sleeved on the outer walls of the linkage shaft 622 and the positioning shaft 621 along the axial direction. A driving shaft 624 is installed on the transmission shaft of the heat dissipation fan 5. A belt 625 is sleeved jointly between the driving shaft 624 and the linkage shaft 622.

[0050] Furthermore, in this embodiment, a steering shaft 626 is rotatably installed on the supporting bracket 62. Two idler gears 627 meshing with the transmission gears 623 on the outer wall of the positioning shaft 621 are sleeved on the outer wall of the steering shaft 626, and the idler gears 627 can mesh with the transmission gears 623 on the outer wall of the linkage shaft 622.

[0051] In the specific implementation process, during the operation of the air conditioner, the heat dissipation fan 5 drives the driving shaft 624 to rotate. The driving shaft 624 drives the linkage shaft 622 to rotate. The linkage shaft 622 drives the positioning shaft 621 to rotate through the transmission gears 623, so that the positioning shaft 621 drives the rotating shaft 612 and the impeller 613 to rotate synchronously, and thus the impeller 613 can drive the water in the first heat dissipation pipe 6 to circulate.

[0052] In the air conditioner refrigeration mode, the positioning shaft 621 drives the rotating shaft 612 and the impeller 613 to rotate forward, so that the impeller 613 controls the water in the circulation pipeline to flow back from the water tank 8 through the first heat dissipation pipe 6 and the second heat dissipation pipe 7 in sequence, so as to cool the condenser 3 and the compressor 2.

[0053] In the air conditioner heating mode, the transmission gear 623 on the outer wall of the linkage shaft 622 is controlled to mesh with the idler gear 627, so that the idler gear 627 can change the rotation direction of the positioning shaft 621, so that the positioning shaft 621 drives the rotating shaft 612 and the impeller 613 to rotate reversely, so that the impeller 613 controls the water in the circulation pipeline to flow back from the water tank 8 through the second heat dissipation pipe 7 and the first heat dissipation pipe 6 in sequence, so that the evaporator 4 can be defrosted after the water absorbs the heat of the compressor 2. It is not necessary to adjust the water supply and drainage pipelines of the water inlet pipe 82 and the water outlet pipe 83 to realize the reverse circulation of the water in the circulation pipeline, and the operation is more convenient.

[0054] Continue to refer to Figure 7As shown, in order to control the transmission gear 623 on the outer wall of the linkage shaft 622 to mesh with the transmission gear 623 or the idler gear 627 on the outer wall of the positioning shaft 621 respectively to control the rotation direction of the impeller 613, the position of the linkage shaft 622 can be adjusted in this embodiment. Specifically, a sliding groove 628 is opened on the support bracket 62, and the linkage shaft 622 is slidably docked in the sliding groove 628. An auxiliary frame 629 is rotatably provided on the linkage shaft 622, and a cylinder 630 is installed on the support bracket 62 through a support frame, and the telescopic end of the cylinder 630 is connected to the auxiliary frame 629.

[0055] It should be noted that the distances between the two ends of the sliding groove 628 and the positioning shaft 621 and the steering shaft 626 are equal, so that when the linkage shaft 622 slides in the sliding groove 628, it can drive the transmission gear 623 on its outer wall to engage with the transmission gear 623 on the outer wall of the positioning shaft 621 or the idler gear 627 respectively.

[0056] During the specific implementation process, the cylinder 630 is started, and the cylinder 630 drives the linkage shaft 622 to move along the sliding groove 628 through the auxiliary frame 629. When the linkage shaft 622 drives the transmission gear 623 on its outer wall to engage with the transmission gear 623 on the outer wall of the positioning shaft 621, the positioning shaft 621 and the impeller 613 can be driven to rotate forward; conversely, when the cylinder 630 drives the transmission gear 623 on the outer wall of the linkage shaft 622 to engage with the idler gear 627, the positioning shaft 621 and the impeller 613 can be reversed through the idler gear 627, so as to automatically control the rotation direction of the impeller 613 according to the heating mode or cooling mode of the air conditioner.

[0057] Reference Figure 8 As shown, after the position of the linkage shaft 622 is adjusted, the distance between the linkage shaft 622 and the drive shaft 624 will change accordingly. Therefore, in order to ensure stable transmission, in this embodiment, the belt 625 between the drive shaft 624 and the linkage shaft 622 can be tensioned accordingly. Specifically, two vertical plates 631 are symmetrically installed along the width direction at the upper end of the support bracket 62, and the opposite sides of the two vertical plates 631 are provided with lifting grooves 632. A displacement block 633 is slidably arranged in the lifting groove 632, and the lower end of the displacement block 633 and the lifting groove 632 are symmetrically installed. A supporting spring rod 634 is installed between 32, and a tensioning wheel 635 is rotatably installed between the two displacement blocks 633 and rests against the inner wall of the belt 625; the supporting spring rod 634 always applies an upward lifting force to the displacement block 633, and the displacement block 633 drives the tensioning wheel 635 to support the belt 625 outward, which is used to elastically tension the belt 625. When the position of the linkage shaft 622 changes, the tensioning wheel 635 can be adaptively ejected or retracted to ensure the transmission connection between the belt 625 and the driving shaft 624 and the linkage shaft 622.

[0058] Reference Figure 10 andFigure 11 As shown, since the water in the circulation pipeline needs to circulate, the water inlet pipe 82 needs to supply water to the water tank 8 all the time, and the water outlet pipe 83 needs to discharge the heated water in the water tank 8 all the time. In actual applications, there may be a situation where hot water is not needed when using the air conditioner. Therefore, in this embodiment, the water in the circulation pipeline can be kept circulating when the water outlet pipe 83 is not discharging water, so as to dissipate heat and defrost the compressor 2, condenser 3 and evaporator 4 when using the air conditioner. Specifically, a conduit 84 for connecting the water inlet area and the drainage area is installed on the baffle 81. The conduit 84 is located above the baffle 81. The opposite ends of the water inlet pipe 82 and the conduit 84 both have inclined cuts. One end of the baffle 81 close to the water inlet area is hinged with a swing plate 85. The swing plate 85 is located between the water inlet pipe 82 and the conduit 84, and two blocking blocks 86 for sealing the water inlet pipe 82 and the conduit 84 respectively are symmetrically arranged on the outer wall of the swing plate 85 along the thickness direction.

[0059] In the specific implementation process, when the hot water in the water tank 8 needs to be used, the water outlet pipe 83 discharges the hot water in the water tank 8. At this time, the water inlet pipe 82 supplies water to the circulation pipeline, so that the water discharged from the water inlet pipe 82 can drive the swing plate 85 to tilt towards the side close to the conduit 84, so that the swing plate 85 seals the conduit 84 through the blocking block 86. At this time, the water source in the water inlet pipe 82 passes through the water inlet area, the circulation pipeline, the drainage area and the water outlet pipe 83 in sequence and then is discharged. That is to say, the heated water in the water tank 8 needs to be used, so that the hot water in the drainage area is discharged through the water outlet pipe 83; in addition, since the water in the drainage area is discharged to the outside, the water in the drainage area cannot reach the saturation state, and thus no reaction force is applied to the swing plate 85. Therefore, the swing plate 85 can seal the conduit 84 through the blocking block 86, avoiding the continuous connection between the water inlet area and the drainage area and affecting the circulation of the water source.

[0060] When the air conditioner is in the on state and hot water is not needed, the water outlet pipe 83 cannot discharge the hot water, and the water inlet pipe 82 supplies water to the water tank 8 all the time. Therefore, the water in the water inlet area and the drainage area gradually becomes saturated, so that the water inlet pipe 82 can no longer supply water. However, the water in the circulation pipeline is still in the circulation state. Therefore, under the action of the impeller 613, the hot water in the drainage area can flow through the conduit 84 into the water inlet area, and then passes through the water inlet area, the circulation pipeline and the drainage area in sequence to form an internal circulation, so as to always keep the heat dissipation and defrosting of the internal equipment of the air conditioner and improve the use performance.

[0061] It should be noted that a connecting pipe 87 for connecting the water inlet area and the water drainage area is installed at the upper end of the water tank 8. A one-way valve (not shown in the figure) is arranged inside the connecting pipe 87. The one-way valve only allows the water in the water inlet area to flow into the water drainage area and does not allow the water in the water drainage area to flow into the water inlet area. Therefore, when the reverse rotation of the impeller 613 controls the reverse circulation of the water source, if the water in the water inlet area is in a saturated state, the water in the water inlet area flows into the water drainage area through the connecting pipe 87 at its upper end, realizing the reverse circulation of the water source and avoiding interference.

[0062] During operation: The first step: The external water supply pipe supplies water to the water tank 8 through the water inlet pipe 82. The water source successively passes through the water inlet area, the first heat dissipation pipe 6, the second heat dissipation pipe 7 and the water drainage area, and finally is discharged through the water outlet pipe 83, so that the water source circulates in the circulation pipeline. The water in the circulation pipeline successively absorbs the heat of the condenser 3 and the compressor 2. Therefore, the water in the circulation pipeline is heated and then flows back into the water tank 8 and is discharged through the water outlet pipe 83 for use, so that the hot water is used for domestic, commercial water, etc.

[0063] The second step: During the operation of the air conditioner, the heat dissipation fan 5 drives the drive shaft 624 to rotate. The drive shaft 624 drives the linkage shaft 622 to rotate. The linkage shaft 622 drives the positioning shaft 621 to rotate through the transmission gear 623, so that the positioning shaft 621 drives the rotating shaft 612 and the impeller 613 to rotate synchronously. Thus, the impeller 613 can drive the water in the first heat dissipation pipe 6 to circulate.

[0064] The third step: In hot summer days, the indoor unit of the air conditioner operates in the cooling mode. The positioning shaft 621 drives the rotating shaft 612 and the impeller 613 to rotate forward, so that the impeller 613 controls the water in the circulation pipeline to flow back from the water tank 8 through the first heat dissipation pipe 6 and the second heat dissipation pipe 7 in sequence, so as to cool down the condenser 3 and the compressor 2.

[0065] In cold winter days, the indoor unit of the air conditioner operates in the heating mode. The cylinder 630 is started. The cylinder 630 drives the linkage shaft 622 to move along the sliding groove 628 through the auxiliary frame 629, so that the transmission gear 623 on the outer wall of the linkage shaft 622 meshes with the idler gear 627. Through the idler gear 627, the positioning shaft 621 and the impeller 613 can be reversed, so that the water in the circulation pipeline can circulate reversely, and the hot water that absorbs the heat on the surface of the compressor 2 passes through the evaporator 4. Thus, the evaporator 4 is defrosted by the hot water, so as to cooperate with the air conditioner to accelerate the defrosting speed.

[0066] Step 4: When the air conditioner is turned on and hot water is not needed, the outlet pipe 83 cannot drain the hot water, while the inlet pipe 82 always supplies water to the water tank 8. Therefore, the water in the water inlet area and the drainage area gradually becomes saturated, so that the inlet pipe 82 can no longer supply water. Therefore, under the action of the impeller 613, the hot water in the drainage area can flow through the conduit 84 into the water inlet area, and then successively pass through the water inlet area, the circulation pipeline and the drainage area to form an internal circulation, so as to always maintain the heat dissipation and defrosting of the internal equipment of the air conditioner and improve the service performance. When the reverse rotation of the impeller 613 controls the reverse circulation of the water source, if the water in the water inlet area is saturated, the water in the water inlet area flows through the connecting pipe 87 at its upper end into the drainage area, realizing the reverse circulation of the water source and avoiding interference.
