Description

Technical Field

[0001] The present invention relates to the technical field related to air conditioners, and in particular to an energy-saving air conditioner with autonomous temperature control of an outdoor unit. Background Art

[0002] As an indispensable component of the air conditioning system, the core function of the air conditioner outdoor unit is to exhaust the hot air in the room, thereby ensuring that the room is maintained within a comfortable temperature range. Its working principle mainly revolves around the compressor and condenser: when the air conditioning system is activated, the indoor unit will actively absorb and accumulate heat from the indoor air, and then this heat will be transferred to the refrigerant flowing through the condenser. As an efficient heat exchange device, the condenser can use the fan-driven airflow to effectively release the heat carried by the refrigerant to the outdoor atmosphere, thereby completing the transfer and discharge of heat.

[0003] In the hot summer, the outdoor unit of the air conditioner faces severe challenges. It not only has to deal with the high temperature caused by direct sunlight, but also needs to use the strong wind of the fan to quickly discharge the large amount of heat released in the condenser. However, due to the high temperature of the external environment and the possible poor air circulation, the heat dissipation efficiency of the condenser is often greatly reduced, which not only causes the temperature of the outdoor unit of the air conditioner to be too high, but also may weaken its cooling capacity, thus affecting the indoor cooling effect.

[0004] The current publication number is CN 116906990 A, which discloses an air conditioner that uses condensed water to dissipate heat, including: an upper water tray, which is arranged inside the air conditioner outdoor unit and is located on the top of the condenser of the air conditioner outdoor unit, and a plurality of drainage holes are provided on the bottom wall of the upper water tray; a guide pipe, one end of which is connected to the water outlet of the air conditioner indoor unit, and the other end is connected to the inside of the upper water tray, so that the condensed water inside the air conditioner indoor unit flows to the inside of the upper water tray. The working principle of this air conditioner is to use the condensed water generated in the air conditioner indoor unit to drip directly from the top of the condenser, thereby cooling the air conditioner condenser. However, since the condensed water rate generated by the air conditioner indoor unit is relatively slow, the amount of condensed water dripping from the condenser is also relatively slow. Therefore, this slower condensed water flow rate seriously affects its heat dissipation effect on the condenser, making the overall cooling effect not significant enough. Summary of the invention

[0005] The present invention provides an energy-saving air conditioner with autonomous temperature control of an outdoor unit, which has the advantage of condensed water-assisted cooling, and is used to solve the problem of poor heat dissipation of the air conditioner outdoor unit at high temperatures mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an energy-saving air conditioner with autonomous temperature control of an outdoor unit, comprising: an outer casing, inside which is a compressor controlled by a power controller, the refrigerant in the compressor flows into the indoor unit of the air conditioner after passing through a condenser, and a heat dissipation fan cools down the heat dissipation fins fixed on the outside of the condenser; a water storage cylinder, fixed on the outer casing, with a water inlet pipe connected to the condensate discharge pipe in the indoor unit of the air conditioner arranged on the top, and a water pump driven by a motor fixedly installed on the bottom of the outer side; a heat dissipation pipe, fixed on the heat dissipation fin, and the bottom is connected to the water pump; a temperature detection probe, fixed on the top of the heat dissipation fin, after the temperature of the heat dissipation fin rises, the temperature detection probe can transmit data to the temperature controller, and the temperature controller is used to start and stop the motor.

[0007] Furthermore, a liquid return joint is threadedly connected to the top of the outer side of the water storage cylinder, the tail end of the liquid return joint is connected to the top of the heat dissipation pipe, a switching valve core is movably installed inside the end of the liquid return joint and is pushed toward the inside of the water storage cylinder by a top spring, a liquid drain groove is opened on the outer side of the liquid return joint, a liquid blocking slider is movably installed on the inner side of the water storage cylinder, and a float is tightly connected to the bottom of the liquid blocking slider.

[0008] Furthermore, a rounded corner is arranged at the end of the switching valve core, and a connecting groove is arranged at the outer side of the switching valve core.

[0009] Furthermore, a stepped hole is provided on the liquid-blocking sliding block.

[0010] Furthermore, a detection switch is fixedly installed on the outside of the water storage cylinder.

[0011] Furthermore, a liquid return pipe is fixedly installed on the liquid blocking slider, a support plate is fixedly installed on one end of the liquid return pipe, a heat sink is installed at the bottom of the support plate, a driving fan blade is fixed on the top of the heat sink, and a leakage hole is opened on the outer side of the surface.

[0012] Furthermore, a support base is fixedly connected to the bottom of the heat dissipation plate, a switching top rod is movably installed on the support base, a pulling head is fixedly installed in the middle of the switching top rod, a switching spring is connected between the pulling head and the support base, a plate sleeve is movably installed on the outer side of the support plate, and the pulling head is pressed against a rectangular groove opened on the outer side of the plate sleeve, and a coil located directly above the support base is fixedly installed on the pulling head, and the coil and the power controller work simultaneously.

[0013] Furthermore, the end of the switching push rod below the leakage hole is conical.

[0014] Furthermore, a bottom cylinder is movably installed at the bottom of the water storage cylinder, a top spring is connected between the bottom of the water storage cylinder and the bottom cylinder, a fixed drainage hole is opened on the outside of the water storage cylinder, a movable drainage hole is opened on the outside of the bottom cylinder, a check valve is installed at the bottom of the water storage cylinder, a one-way air intake valve is fixedly installed at the bottom of the bottom cylinder, a limiting pressure plate located above the switching top rod is fixedly installed on the top of the bottom cylinder, and a driving block is fixedly installed at the bottom of the limiting pressure plate.

[0015] Furthermore, a guide groove is provided on the outer side of the bottom cylinder, and the bolt passes through the guide groove and is screwed onto the water storage cylinder.

[0016] The present invention has the following beneficial effects: The present invention provides an energy-saving air conditioner with autonomous temperature control of the outdoor unit. During the operation of the indoor unit, the condensed water generated is guided to the water storage cylinder inside the outdoor unit through a specially designed water inlet pipe for storage. In order to monitor the heat dissipation of the outdoor unit in real time, the system is equipped with a high-precision temperature detection probe, which fits tightly on the heat dissipation fins and can accurately capture the real-time temperature of the heat dissipation fins, and quickly transmit this key data to the temperature controller. As the "brain" of the entire system, the temperature controller is responsible for receiving and analyzing temperature data and responding according to the preset algorithm logic.

[0017] When the temperature of the cooling fins exceeds the preset safety threshold, the temperature controller will instruct the motor to start. Once the motor starts, it will drive a set of water pumps to pump the condensed water stored in the water storage cylinder to the heat pipes. The heat pipes are cleverly wrapped around the cooling fins to form an efficient heat exchange network. When the condensed water flows in the heat pipes, it can fully absorb the heat on the cooling fins. Subsequently, the condensed water carrying the heat is safely discharged through a specific discharge pipe, thereby achieving the purpose of effectively taking away the heat from the cooling fins.

[0018] This process not only significantly reduces the temperature of the heat dissipation fins, preventing potential failures of the outdoor unit due to overheating, but also further improves the overall energy efficiency of the air conditioning system. The recycling of condensed water not only reduces the waste of water resources, but also provides an additional, environmentally friendly cooling method for the outdoor unit through its natural evaporation heat absorption characteristics.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention aims to recycle the condensed water produced by the indoor unit, thereby assisting the outdoor unit of the air conditioner to dissipate heat efficiently. For details, please refer to Figure 1 and Figure 2 , which is the same as the external structure of the current air conditioner, is that a compressor 4 is arranged inside the outer casing 1. The power controller 5 fixed on the inner side of the outer casing 1 can control the operation of the compressor 4, and the compressor 4 and the condenser 6 are connected through the copper tube; secondly, the treated refrigerant is transported to the indoor unit of the air conditioner through the copper tube, so that the indoor unit can perform refrigeration. During the application process, the heat dissipation motor is used to drive the heat dissipation fan 2 to rotate on one side of the heat dissipation fin 3, so as to realize the cooling of the heat dissipation fin 3 connected to the condenser 6. As for the setting of other components (such as the water guide plate at the bottom of the outer casing 1, etc.), it is a well-known and commonly used method in the industry, and will not be described in detail here.

[0024] Unlike the current air conditioner outdoor unit, the reference Figure 1 It can be seen that the difference from the existing commonly used outdoor unit is that the outer casing 1 is fixedly connected with a water inlet pipe 8, which is generally connected to the condensed water discharge pipe in the indoor unit of the air conditioner. When the indoor unit is cooling, the generated condensed water will flow from the water inlet pipe 8 into the interior of the outer casing 1. Figure 3 and Figure 8 It can be seen that the condensed water transported through the water inlet pipe 8 will eventually be collected and stored in the water storage cylinder 9. The water storage cylinder 9 is clamped by a clamp and fastened to the outer casing 1 with bolts to ensure that the water storage cylinder 9 can be stably arranged inside the outer casing 1. Figure 4 , Figure 7 and Figure 8 It can be seen that a water pump 26 for sucking condensed water from the inner cavity of the water storage cylinder 9 is fixedly installed at the outer bottom of the water storage cylinder 9, and the water pump 26 is driven by the motor 25. A heat dissipation pipe 7 is fixed at the output end of the water pump 26. Figure 3 It can be clearly seen that the condenser 6 and the heat dissipation tube 7 are both fixedly distributed on the heat dissipation fin 3. When the water pump 26 transports the medium in the water storage cylinder 9 to the heat dissipation tube 7, the temperature of the heat dissipation fin 3 can be reduced through the heat dissipation tube 7, thereby reducing the temperature of the condenser 6.

[0025] Moreover, in order to facilitate the control of the water pump 26, Figure 2 , Figure 3 and Fig.16It can be clearly known that a temperature detection probe 11 for detecting the temperature is fixedly installed on the top of the heat dissipation fin 3, and the temperature detection probe 11 is generally fixed by a bracket. The temperature data detected by the temperature detection probe 11 will be transmitted to the temperature controller 10 fixed in the outer casing 1. The temperature of the heat dissipation fin 3 is analyzed by the temperature controller 10. When the temperature of this part is higher than the set value, it means that the heat dissipation fin 3 is working at a high temperature. The temperature controller 10 is used to drive the motor 25 to start working, so that the condensed water stored in the water storage cylinder 9 is transported to the heat dissipation pipe 7 through the water pump 26, and the heat dissipation pipe 7 is used to reduce the temperature of the heat dissipation fin 3, thereby realizing the secondary utilization of the condensed water. Not only that, Figure 3 It can be seen that the temperature detection probe 11 is located at the top of the heat dissipation fin 3 and close to the water outlet of the heat dissipation pipe 7. When the heat dissipation pipe 7 is cooled by the condensed water flowing inside, if the temperature detected by the temperature detection probe 11 is lower than the preset temperature, it means that the temperature of the entire heat dissipation fin 3 is relatively reduced. The temperature controller 10 will control the motor 25 to stop working. This benefit enables the motor 25 to work in a timely manner and avoids the problem of increased energy consumption caused by long-term startup.

[0026] On this basis, reference Figure 4 and Figure 5 It can be seen that the outer top of the water storage cylinder 9 is threadedly connected with a liquid return joint 15, and the tail end of the liquid return joint 15 is connected to the top of the heat dissipation pipe 7. Figure 5 , Figure 8 and Fig.11 As shown, a switching valve core 17 is movably installed inside the end of the return liquid joint 15, which is pushed toward the inside of the water storage cylinder 9 by a top spring. Under normal conditions, the switching valve core 17 is pushed outward by the top spring, and its outer side is used to block the drainage groove 150 opened on the outer side of the return liquid joint 15. Therefore, the drainage groove 150 is in a blocked state under normal conditions. Correspondingly, a liquid blocking slider 13 is movably installed inside the water storage cylinder 9. The liquid blocking slider 13 can only move up and down a certain range along the axial direction of the water storage cylinder 9, and from Fig.13 It can be seen that the end of the switching valve core 17 is provided with a rounded corner, which will hit the cylindrical hole opened on the liquid blocking slider 13 (the cylindrical hole is a stepped hole to avoid the problem of locking when the switching valve core 17 is inserted), which will cause a certain movement resistance when the liquid blocking slider 13 moves upward. Figure 4 , Figure 5 and Fig.12It can be seen that the bottom of the liquid retaining slider 13 is fastened with a float 16. When the amount of water stored in the water storage cylinder 9 increases, the buoyancy of the float 16 increases, thereby pushing the liquid retaining slider 13 upward. The upward liquid retaining slider 13 will cause the end of the switching valve core 17 to detach from the cylindrical hole, and use the inner wall of the liquid retaining slider 13 to reach the end of the switching valve core 17. After the switching valve core 17 detaches from the stepped hole, it will tend to compress the top spring, and use the connecting groove 170 opened on the outside of the switching valve core 17 to directly discharge the condensed water in the return liquid joint 15 from the drain groove 150. In order to make the motor 25 start automatically when the condensed water inside the water storage cylinder 9 increases, combined with the Figure 5 It can be seen that a detection switch 18 is fixedly installed on the outside of the water storage cylinder 9. The detection switch 18 is normally pressed by the switching valve core 17, and the pressed detection switch 18 will not be turned on. When the switching valve core 17 moves away from the detection switch 18, the detection switch 18 can directly turn on and start the motor 25, so that the motor 25 drives the water pump 26 to suck, thereby avoiding excessive condensed water from being stored in the water storage cylinder 9.

[0027] As mentioned above, when the medium in the water storage cylinder 9 is pumped out by the water pump 26, the liquid level of the condensed water in the water storage cylinder 9 will drop, and the floating force of the float 16 cannot be maintained. As the condensed water decreases, the float 16 and the liquid retaining slider 13 move downward under gravity until the switching valve core 17 hits the stepped hole on the liquid retaining slider 13 again, and the switching valve core 17 presses the detection switch 18 again, and at the same time blocks the drain groove 150 again. It can be seen from this that when the water is continuously transported to the water storage cylinder 9 through the water inlet pipe 8, the motor 25 can be started intermittently, which makes the condensed water in the heat dissipation pipe 7 flow out intermittently, avoiding the temperature on the heat dissipation fin 3 from continuing to rise. Furthermore, although the float 16 has a tendency to move upward after the liquid level in the water storage cylinder 9 rises, the upward force of the float 16 is not enough to overcome the switching valve core 17 when it is separated from the stepped hole, and its liquid level will continue to rise. By designing the actual height of the float 16, it can be ensured that during the rising process of the liquid level, the condensed water stored in this stage can be completely input into the heat pipe 7, so that when the motor 25 is started due to excessive condensed water in the water storage cylinder 9, the condensed water with increased temperature in the heat pipe 7 can be completely discharged to the outside through the drainage groove 150, and finally flow downward through the water guide plate at the bottom of the outer casing 1.

[0028] Moreover, if the amount of condensed water stored in the water storage cylinder 9 is insufficient, due to the cooperation between the stepped hole on the liquid retaining slider 13 and the switching valve core 17, when the motor 25 is started due to the temperature detection probe 11 detecting that the temperature is too high, the medium in the heat dissipation pipe 7 will return to the water storage cylinder 9 through the liquid retaining slider 13, thus avoiding the problem of medium waste when the amount of condensed water in the water storage cylinder 9 is small. On this basis, since the temperature of the medium transported by the return liquid joint 15 is relatively high, in order to facilitate cooling the heated condensed water, combined with Figure 4 , Figure 6 , Figure 12-Figure 15 It can be seen that a liquid return pipe 14 connected to the stepped hole is fixedly installed on the liquid retaining slider 13, and a support plate 19 is fixedly installed on the other end of the liquid return pipe 14. A heat sink 21 limited by a clamping ring is provided at the bottom of the support plate 19. The clamping ring is mainly connected to the bottom of the support plate 19 by threads to prevent the heat sink 21 from falling off the support plate 19. A plurality of inclined driving blades 211 are fixed on the top of the heat sink 21, and a plurality of leakage holes 210 arranged at equal angles are opened on the outer side of the surface. When the condensed water in the liquid return pipe 14 flows between the support plate 19 and the heat sink 21, it will first pass through the driving blades 211, and the driving blades 211 drive the heat sink 21 to rotate, and the condensed water passing through the driving blades 211 will be ejected from the leakage holes 210. Since the leakage holes 210 are dispersed in an annular shape, the heat exchange area between the condensed water flowing out of the leakage holes 210 and the external air will be increased, making it easier to cool down.

[0029] More importantly, the bottom of the heat sink 21 is fixedly connected to a support base 222, which is mainly made of metal and easily attracted by magnetism. A "U"-shaped switching top rod 22 is movably mounted on the support base 222, and one end of the switching top rod 22 is located below the drain hole 210. In more detail, combined with Fig.13 It can be seen that the switching push rod 22 at this end is set to be conical. On the one hand, when the switching push rod 22 is inserted into the drain hole 210, the drain hole 210 can be cleared and blocked. On the other hand, when the switching push rod 22 moves below the drain hole 210, the water column sprayed downward from the drain hole 210 directly hits the conical end of the switching push rod 22, which can further disperse the condensed water. A pull sleeve 221 is fixedly installed in the middle of the switching push rod 22, and a switching spring 220 is connected between the pull sleeve 221 and the support base 222. Under the push of the elastic force of the switching spring 220, the switching push rod 22 always has a tendency to move upward until the switching push rod 22 is fully inserted into the drain hole 210. In addition, a plate sleeve 20 is movably installed on the outer side of the support plate 19, and the pull sleeve head 221 is against the corresponding rectangular groove opened on the outer side of the plate sleeve 20. When the pull sleeve head 221 moves up to the top, it will drive the plate sleeve 20 to move upward synchronously until the plate sleeve 20 is away from the heat sink 21. At this time, there is no obstruction between the heat sink 21 and the outer side of the support plate 19, and the spacing area between the two will be directly connected to the outside, that is, Fig.13 Status shown.

[0030] A coil 23 located directly above the support base 222 is fixedly installed on the pull head 221. The coil 23 and the power controller 5 work simultaneously. Specifically, when the power controller 5 is powered off, the coil 23 will no longer work. When the power controller 5 is working, the coil 23 works and generates magnetism. After the coil 23 generates magnetism, it will attract the support base 222, thereby pulling the pull head 221 to compress the switching spring 220 and disengage the switching top rod 22 from the leakage hole 210. In addition, the downward pull head 221 will eventually cause the plate sleeve 20 to move downward and block it to the outside of the heat sink 21.

[0031] In order to enhance heat dissipation and subsequently discharge the condensed water in the water storage cylinder 9, Figure 4-Figure 10 It can be seen that a bottom cylinder 12 is movably mounted at the bottom of the water storage cylinder 9. Generally speaking, a guide groove is provided on the outer side of the bottom cylinder 12. Figure 7 As shown, the bolt passes through the guide groove and is screwed onto the water storage cylinder 9, which limits the bottom cylinder 12 to only move up and down on the one hand, and limits the range of motion of the bottom cylinder 12 on the other hand. A top spring is connected between the bottom of the water storage cylinder 9 and the bottom cylinder 12, and the bottom cylinder 12 always has a tendency to move downward under the push of the top spring elastic force. A fixed drainage hole 900 is provided on the outside of the water storage cylinder 9, and correspondingly, a movable drainage hole 120 is provided on the outside of the bottom cylinder 12. When the fixed drainage hole 900 and the movable drainage hole 120 are connected, the movable drainage hole 120 can be used to discharge the condensed water stored in the water storage cylinder 9. The bottom of the water storage cylinder 9 is equipped with a check valve 901 which is connected to the inner cavity of the bottom cylinder 12. The check valve 901 realizes the one-way delivery of the airflow in the inner cavity of the bottom cylinder 12 to the water storage cylinder 9. Similarly, the bottom of the bottom cylinder 12 is fixedly equipped with a one-way air inlet valve 121 which can deliver the airflow to its inner cavity in one direction. When the bottom cylinder 12 moves up and down, the external airflow can be input into the water storage cylinder 9 through the inner cavity of the bottom cylinder 12. Figure 6 , Fig. 9 and Fig.10 It can be seen that a limiting pressure plate 24 located above the switching top rod 22 is fixedly installed on the top of the bottom cylinder 12 , and a driving block 240 in the shape of a triangular prism is fixedly installed on the bottom of the limiting pressure plate 24 .

[0032] When the present invention is working, under normal conditions, under the push of the switching spring 220, the switching push rod 22 passes through the drain hole 210, and the pull sleeve head 221 drives the plate sleeve 20 upward and away from the heat sink 21. The upward switching push rod 22 reaches the bottom of the limiting pressure plate 24 and pushes it to move upward synchronously. The limiting pressure plate 24 drives the bottom cylinder 12 to move upward, so that the bottom cylinder 12 moves upward to the limit, that is, Figure 7In the position shown, the bottom of the guide groove outside the bottom cylinder 12 abuts against the bolt, and the bottom of the water storage cylinder 9 abuts against the bottom cylinder 12. At this time, the top spring between the bottom cylinder 12 and the water storage cylinder 9 is compressed, the fixed drainage hole 900 and the movable drainage hole 120 are connected, and the condensed water in the water storage cylinder 9 is discharged, ensuring that no condensed water is stored in the water storage cylinder 9 when the air conditioner is not working. When there is no condensed water in the water storage cylinder 9, the liquid retaining slider 13 and the float 16 have a tendency to move downward due to gravity and the switching spring 220 pushing the support base 222, forcing the return liquid pipe 14 to also have a tendency to pull the liquid retaining slider 13 downward until the liquid retaining slider 13 descends to the bottom limit. Under the elastic force of the top spring, the switching valve core 17 will make the arc end of the switching valve core 17 abut against the stepped groove of the liquid retaining slider 13. So far, it is the normal state when the entire external unit is stopped.

[0033] When cooling is required, the power controller 5 is started and the compressor 4 and the coil 23 start working; the compressor 4 works and the refrigerant is transported to the air-conditioning indoor unit after passing through the condenser 6; the coil 23 starts to work and generates magnetism and attracts the support base 222. Finally, under the magnetic attraction of the coil 23, the pull head 221 drives the switching top rod 22 to move downward, on the one hand, making the switching top rod 22 away from the leakage hole 210, and after the pull head 221 moves downward, it drags the plate sleeve 20 to move downward synchronously until the plate sleeve 20 blocks the outer side of the heat sink 21 and the support plate 19; on the other hand, when the switching top rod 22 moves downward and away from the limiting pressure plate 24, the bottom cylinder 12 is pushed downward by the elastic force of the top spring, and the fixed drainage hole 900 and the movable drainage hole 120 are staggered, and the fixed drainage hole 900 is blocked by the inner side of the bottom cylinder 12, but at this time there is still a distance between the limiting pressure plate 24 and the switching top rod 22.

[0034] As the indoor unit of the air conditioner starts to work, the generated condensed water will flow into the water storage cylinder 9 through the water inlet pipe 8 and be stored in the water storage cylinder 9.

[0035] After working for a long time, if the temperature detection probe 11 detects that the temperature of the heat dissipation fin 3 rises too high, it will transmit data to the temperature controller 10, and the temperature controller 10 controls the motor 25 to start, and the motor 25 drives the water pump 26 to work, so that the condensed water stored in the water storage cylinder 9 is transported to the heat dissipation pipe 7. If the condensed water medium in the water storage cylinder 9 is relatively small, that is, there is a certain distance between the condensed water liquid level and the float 16, the float 16 will not be able to push the liquid blocking slider 13 upward. The condensed water transported through the heat dissipation pipe 7 will pass through the liquid return joint 15, and the condensed water will pass through the stepped hole of the liquid blocking slider 13 and enter the liquid return pipe 14. When the condensed water input from the liquid return pipe 14 passes through the driving blade 211, it will drive the heat sink 21 to rotate, and the condensed water after passing through the driving blade 211 will be sprayed out from the leakage hole 210. Since the switching top rod 22 with a tapered end is located below the leakage hole 210, the condensed water will be dispersed again after being sprayed out from the leakage hole 210 through the tapered switching top rod 22, thereby increasing the relative contact area with the air, thereby providing more efficient heat dissipation.

[0036] Moreover, when the heat sink 21 rotates, the switching top rod 22 will be driven to rotate synchronously through the supporting base 222. When the top of the switching top rod 22 passes through the driving block 240, the switching top rod 22 will hit the inclined surface of the driving block 240, forcing the driving block 240 to drive the bottom cylinder 12 to move upward. At this time, the bottom cylinder 12 moving upward will press the airflow in the inner cavity from the check valve 901 into the inner cavity of the water storage cylinder 9. The airflow passes through the inner cavity of the water storage cylinder 9. On the one hand, the air takes away the temperature of the condensed water in the water storage cylinder 9. On the other hand, when the air passes through the condensed water and flows upward, the airflow passes through the water spraying range of the leakage hole 210, thereby further aggravating the cooling of the condensed water. It should be noted that at this time, when the driving block 240 is pushed upward by the switching top rod 22, it will only cause the bottom cylinder 12 to move upward for a certain distance, but the fixed drainage hole 900 will not be connected with the movable drainage hole 120. When the switching push rod 22 rotates with the support base 222 and passes over the driving block 240, the bottom cylinder 12 moves downward again under the push of the top spring force between the bottom cylinder 12 and the water storage cylinder 9, and the inner cavity of the bottom cylinder 12 inhales air flow through the one-way air intake valve 121. According to the above cycle, the bottom cylinder 12 moves up and down continuously, and provides air flow that continuously flows upward to the water storage cylinder 9. Finally, until the temperature of the heat dissipation fin 3 decreases, the temperature detection probe 11 transmits the detection value to the temperature controller 10, and the temperature controller 10 stops the motor 25.

[0037] If the water inlet pipe 8 continuously delivers condensed water to the water storage cylinder 9, the condensed water stored in the water storage cylinder 9 will continue to increase. When the liquid level is higher than the float 16 and the buoyancy of the float 16 overcomes the resistance between the liquid retaining slider 13 and the switching valve core 17, the upwardly moving liquid retaining slider 13 tends to push the switching valve core 17 to move to the left. After that, the liquid retaining slider 13 continuously moves upward under the action of buoyancy, and blocks the end of the switching valve core 17 through the side. The switching valve core 17 moving to the left compresses the top spring and releases the squeezing of the detection switch 18. After the detection switch 18 is turned on, the motor 25 starts to work. At this time, the condensed water output from the heat pipe 7 will pass through the connecting groove 170 and then be discharged from the drain groove 150, thereby avoiding excessive condensed water stored in the heat pipe 7. As the water pump 26 continuously sucks the condensed water in the water storage cylinder 9, the liquid level of the condensed water in the water storage cylinder 9 drops, and the liquid blocking slider 13 also drops synchronously until the switching valve core 17 again reaches the stepped hole of the liquid blocking slider 13. Afterwards, the switching valve core 17 presses the detection switch 18 again under the elastic force of the top spring, and at the same time blocks the drain groove 150.

[0038] Finally, if the air conditioner stops working, the coil 23 will also stop working. The switching push rod 22 will move upward under the elastic force of the switching spring 220, and the switching push rod 22 will first pass through the leakage hole 210, so that the impurities blocked in the leakage hole 210 will be pushed between the heat sink 21 and the support plate 19. As the pull sleeve head 221 continues to move upward, the plate sleeve 20 will move upward and away from the heat sink 21. At this time, the condensed water remaining in the return pipe 14 is directly discharged from the gap between the support plate 19 and the heat sink 21, and the impurities blocked in the leakage hole 210 are discharged into the water storage cylinder 9. Afterwards, under the upward push of the switching push rod 22, the limit pressure plate 24 will move upward and return to the normal position mentioned above. Afterwards, the condensed water in the water storage cylinder 9 is discharged from the active drainage hole 120, and since the water pump 26 is located at the bottom of the heat pipe 7 and is higher than the active drainage hole 120, the condensed water in the heat pipe 7 will also flow back from the water pump 26 to the water storage cylinder 9 under gravity. In addition, during the reflux of the condensed water in the heat pipe 7, since the plate sleeve 20 is far away from the heat plate 21, the spacing between the support plate 19 and the heat plate 21 can ensure that the pressure inside the heat pipe 7 is always balanced with the outside, so that the condensed water in the heat pipe 7 can be discharged outward. Finally, all the condensed water in the heat pipe 7 and the water storage cylinder 9 will be discharged outward, and the outside of the air conditioner will return to the normal position again.
