Description

Technical Field

[0001] This invention relates to the field of water heater technology, and in particular to a circulating water tank for an air source water heater and its working method. Background Technology

[0002] Air source heat pump water heaters, also known as "air source heat pump water heaters," work on a similar principle to air conditioners. They use a small amount of electricity to drive the compressor, and the high-pressure liquid working fluid evaporates into a gaseous state in the evaporator after passing through the expansion valve, absorbing a large amount of heat energy from the air. Air source heat pump water heaters require the use of a circulating water tank.

[0003] While most existing circulating water tanks can simultaneously perform water replenishment and heating, significant drawbacks remain: during replenishment, the low-temperature cold water entering the tank easily forms a localized cold water layer. If the water is completely still, this cold water layer solidifies, resulting in slow water mixing after replenishment and prolonged heating time. Furthermore, continuous strong perturbation by blades causes extensive mixing of hot and cold water, leading to a drop in the temperature of the upper stored hot water and poorer water quality. These issues result in low heat exchange efficiency and large temperature fluctuations in the water tank, making it impossible to simultaneously meet the needs of replenishing water and providing heating. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a circulating water tank for an air source water heater and its working method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circulating water tank for an air source heat pump water heater includes a tank body and further includes:

[0007] A flow-disrupting component is disposed within the water tank body and is used to disrupt the flow of water within the water tank body;

[0008] Water supply pipeline, including a water supply pipe installed on the lower side of the water tank body and a hot water pipe installed on the upper side of the water tank body;

[0009] The circulating water pipeline includes a return water pipe and an outlet water pipe installed on the water tank body. A circulating pump and an air source heat pump heat exchanger are installed between the return water pipe and the outlet water pipe to form a closed-loop circulating heat exchange circuit.

[0010] And a central ring, which can adaptively rise and fall with the water level in the water tank body. The central ring has a cavity inside, which is divided by a partition into a drain cavity that cooperates with the water supply pipe and a water inlet cavity that cooperates with the water outlet pipe. The drain cavity has a drain outlet, and the water inlet cavity has a water inlet.

[0011] The turbulence component is equipped with an adjustment component for adjusting the turbulence angle of the turbulence component, and the adjustment component is adaptively driven by the water pressure difference inside the water supply pipe.

[0012] Preferably, the turbulence assembly includes a turbulence motor fixed to the top of the water tank body, a turbulence shaft connected to the output shaft of the turbulence motor, and unequally spaced turbulence blades along the axial direction of the turbulence shaft.

[0013] Preferably, the disturbance shaft has a movable groove for the movement of the disturbance blades, and a support plate is fixed on the inner wall of the movable groove. The support plate is rotatably connected to the disturbance blades through a pin.

[0014] Preferably, the adjustment assembly includes a slide plate slidably connected to the disturbance shaft, a connecting rod hinged between the slide plate and each disturbance blade, and a drive unit connected to the slide plate and driven by the pressure difference of the water flow inside the water supply pipe.

[0015] Preferably, the drive unit includes a connecting plate fixed to the bottom of the connecting rod, an elastic telescopic member disposed between the connecting plate and the bottom of the disturbance shaft, a connecting sleeve rotatably connected to the connecting plate, and a force-bearing rod fixed to the lower side of the connecting sleeve.

[0016] Preferably, the water supply pipe has a groove, and an elastic membrane is provided in the groove to move against the bottom of the force-bearing rod. The inner wall of the water supply pipe is also rotatably connected to a swing plate that moves against the elastic membrane via a pin.

[0017] Preferably, the turbulence blade is configured as a plate blade, and the plate blade has a guide surface on both sides;

[0018] When the regulating component is not driven by the water flow in the water supply pipe, the turbulence-disrupting blades are arranged at an angle;

[0019] When the regulating component is driven by the water flow in the water supply pipe, the turbulence-disrupting blades are arranged horizontally.

[0020] Preferably, the disturbance shaft is provided with an adaptive adjustment component for adjusting the position of the centering ring. The adaptive adjustment component includes a fixed seat fixed to the lower side of the disturbance shaft, a buoyancy seat slidably connected to the upper side of the disturbance shaft, a swing rod hinged to the fixed seat and the buoyancy seat respectively, a connecting block hinged together with the two swing rods, a telescopic rod connected to the end of the connecting block away from the swing rod, and a slider connected to the telescopic end of the telescopic rod. The inner sidewall of the centering ring is provided with an annular groove that cooperates with the slider. The centering ring is slidably connected to the inner wall of the water tank body.

[0021] Preferably, a water guide pipe is provided between the water supply pipe and the drainage chamber, and between the water outlet pipe and the water inlet chamber. The water guide pipe is a spiral flexible hose or a telescopic pipe.

[0022] This invention also discloses a method for operating a circulating water tank in an air source water heater, comprising the following steps:

[0023] S1: When the user uses water, the water level in the water tank drops. Tap water enters the water tank through the water supply pipe. At the same time, the circulation pump starts and draws water from the water tank through the water outlet pipe. After being heated by the air source heat pump heat exchanger, the water flows back to the water tank through the return pipe.

[0024] Then the spoiler motor starts, driving the spoiler shaft to rotate, and the spoiler blades rotate with the spoiler shaft;

[0025] S2: When water flows through the water supply pipe, the water flow impacts the swing plate, the swing plate rotates around the pin shaft, pushing the elastic membrane to deform upward. The elastic membrane pushes the force rod, and the force rod drives the connecting plate to move upward through the connecting sleeve. The connecting plate compresses the elastic telescopic component and pushes the slide plate to slide upward along the disturbance axis. When the slide plate moves upward, it pulls each turbulence blade to rotate around the pin shaft on the support plate through the connecting rod. The turbulence blade gradually changes from an inclined state to a horizontal state.

[0026] When the horizontally positioned turbulence blades rotate with the turbulence axis, the area facing the water body decreases, and the turbulence intensity decreases.

[0027] S3: As water is replenished, the water level in the tank gradually rises. The buoyancy seat is buoyed and slides upward along the disturbance axis. The two swing rods between the buoyancy seat and the fixed seat make a scissor-like motion. The position of the connecting block is automatically adjusted accordingly, always remaining in the middle of the water. When the position of the connecting block changes, the telescopic rod automatically extends and retracts to adapt to the change in distance between the connecting block and the centering ring, so that the centering ring is always in the middle of the water.

[0028] S4: When the water level in the tank reaches the set height, the tap water stops replenishing, the water flow in the water supply pipe disappears, the swing plate is no longer impacted by the water flow, and resets under the action of gravity and elasticity. The elastic membrane loses external force and returns to its original state. The elastic expansion component releases elastic potential energy, pushes the connecting plate down, and drives the slide plate to slide down and reset along the disturbance axis. The slide plate pulls the turbulence blades to rotate through the connecting rod, and the turbulence blades return from the horizontal state to the inclined arrangement state.

[0029] S5: After the turbulence blades return to their tilted state, the frontal area increases as they rotate with the turbulence shaft, which enhances the turbulence force on the water body and fully agitates the water in the tank body, so that the cold water at the bottom and the hot water at the top are mixed and heated evenly, breaking the temperature gradient formed during water replenishment.

[0030] S6: When the water temperature inside the water tank reaches the set temperature, the air source heat pump heat exchanger stops, the circulation pump stops, the turbulence motor stops running, the turbulence blades remain still, and the water tank maintains a uniform hot water state for user use.

[0031] Compared with the prior art, the present invention provides a circulating water tank for an air source water heater and its working method, which has the following beneficial effects:

[0032] 1. This invention operates in parallel with water replenishment and heating cycles, eliminating the need to stop the machine and wait for water replenishment to complete. The central ring adapts to the water level and remains in the middle of the water body. Cold water is discharged into the water tank from the middle, and the circulating heat exchange also draws water from the middle, avoiding direct impact of low-temperature cold water on the top high-temperature water storage area or the bottom area. In conjunction with the water replenishment operation, the turbulence blades switch to a horizontal weak disturbance state, suppressing large-scale mixing of hot and cold water, effectively preventing the rapid drop in the temperature of the hot water at the top, ensuring a stable domestic hot water outlet temperature, and improving the water use experience.

[0033] 2. This invention, through adaptive switching of turbulence intensity, eliminates the need for an additional independent electronic control sensor. During water replenishment, the mechanism is driven by the impact of water flow in the pipeline to cause weak turbulence of the blades, preventing the water from becoming completely still and forming solidified cold water stratification, thus preventing slow mixing during subsequent heating. After water replenishment, the elastic telescopic component automatically resets, and the turbulence blades return to their tilted posture to achieve strong turbulence, quickly eliminating water temperature stratification inside the water tank, shortening the water temperature equalization time, and improving the overall heating efficiency.

[0034] 3. This invention, by setting up a buoyancy and scissor-type adaptive positioning component, drives the centering ring to rise and fall with the actual water level of the water tank, always positioning it in the middle of the water body. The water guide pipeline adopts a spiral flexible hose or telescopic pipe to adapt to the vertical displacement of the centering ring, continuously ensuring the smooth flow of the pipeline. It overcomes the defects of the fixed water inlet and outlet positions of traditional water tanks. It can achieve middle layer water distribution and middle layer water intake under different water level conditions, optimizes the internal temperature field distribution of the water tank, makes the heat pump inlet water temperature more stable, and reduces the frequent start-up and shutdown of the unit.

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, this embodiment proposes a circulating water tank for an air source heat pump water heater, including a tank body 1. The tank body 1 is equipped with a flow-turbulence component and a central ring 6. The tank body 1 is equipped with a water supply pipe and a circulating water pipe on the outside. The water supply pipe includes a water replenishment pipe 2 and a hot water pipe 3. The water replenishment pipe 2 is located on the lower side of the tank body 1 and is used to replenish cold water into the tank. The hot water pipe 3 is located on the upper side of the tank body 1 and is used to output high-temperature domestic water. The circulating water pipe includes a return water pipe 4 and an outlet water pipe 5. The return water pipe 4 and the outlet water pipe 5 are respectively located on the tank body 1. A circulating pump and an air source heat pump heat exchanger are connected in series between them to form a closed-loop circulating heat exchange circuit. The circulating pump provides the water flow power. After the water flows through the air source heat pump heat exchanger and completes heat absorption and temperature rise, it is sent back to the tank body 1 through the return water pipe 4 to realize continuous heat exchange and heating of the water in the tank. The circulating pump and the air source heat pump heat exchanger are existing technologies and will not be described in detail here.

[0050] The central ring 6 is slidably installed on the inner wall of the water tank body 1, and can adaptively rise and fall with the changes in the water level inside the water tank body 1. The central ring 6 has a cavity 7 inside, which is divided into an independent drain cavity and a water inlet cavity by a partition. The drain cavity has a drain outlet 701 for draining water, and the water inlet cavity has a water inlet 702 for water intake. Water supply pipe 2 is connected to the drain cavity and the outlet pipe 5 is connected to the water inlet cavity by water guide pipe 16. The water guide pipe 16 is a spiral flexible hose or a telescopic pipe. The water guide pipe 16 can expand and contract with the vertical rise and fall of the central ring 6, continuously maintaining the pipeline connection. It will not cause the pipeline to break or disconnect due to the change of the position of the central ring 6, ensuring the continuous smooth flow of the water supply and circulation water intake channels.

[0051] Cold water is distributed from the drain chamber of the central ring 6 to the middle layer of the water tank, while the circulating heat exchange water is drawn from the middle layer through the inlet chamber of the central ring 6. The low-temperature cold water is confined to the middle layer, preventing it from directly impacting the high-temperature storage area at the top of the tank, diluting the stored hot water, or directly impacting the bottom area, stirring up deposited dirt and avoiding water quality deterioration caused by water replenishment. The water in the middle layer itself has a relatively uniform temperature, and continuous water intake from the middle layer can deliver water with smaller temperature fluctuations to the heat pump heat exchanger, optimizing the overall temperature field distribution inside the water tank, stabilizing the heat pump inlet water temperature, reducing frequent changes in the heat pump unit's compression load, reducing frequent start-ups and shutdowns of the unit, improving the heat exchange efficiency of the air source heat pump, and also ensuring the stability of the domestic hot water temperature output from the upper hot water pipe 3.

[0052] It should be noted that although both water replenishment and circulation are completed by the central ring 6 in the middle layer of the water tank, there will be no situation where the circulating water pump continuously draws the newly added low-temperature cold water. On the one hand, under the water replenishment condition, the turbulence blade 802 switches to a horizontal weak disturbance state, generating only a weak water flow. The replenished low-temperature cold water will slowly sink downwards in the middle layer under the action of gravity. Moreover, the drain outlet 701 is located on the lower side of the central ring 6, and the inlet 702 is located on the upper side of the central ring 6, so it will not immediately rush into the inlet chamber in large quantities. On the other hand, the high-temperature circulating return water of the water tank flows back from the upper return water pipe 4 of the water tank. The upper high-temperature water slowly transfers heat downwards by natural heat conduction, continuously heating the middle layer cold water, so that the water in the middle layer gradually heats up. At the same time, the drain chamber and the inlet chamber of the central ring 6 are completely separated by the partition inside the cavity 7. The cold water from the water replenishment pipe 2 first enters the independent drain chamber and then is discharged outwards into the middle layer space of the water tank. The drain chamber and the inlet chamber are not directly connected. The replenished cold water must first diffuse into the middle layer of the water in the water tank body 1 before it can be drawn by the inlet chamber. There is no way for the cold water to be directly sucked into the circulation pipe without mixing with the water.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, in a preferred embodiment, based on the above method, a further step is to install a turbulence-dispersing component inside the water tank body 1 to agitate and mix the water inside the tank. The turbulence-dispersing component includes a turbulence-dispersing motor 8, a turbulence-dispersing shaft 801, and several turbulence-dispersing blades 802. The turbulence-dispersing motor 8 is fixedly installed on the top of the water tank body 1, and the output shaft of the turbulence-dispersing motor 8 is fixedly connected to the turbulence-dispersing shaft 801. Multiple sets of turbulence-dispersing blades 802 are equidistantly arranged along the axial direction of the turbulence-dispersing shaft 801. The turbulence-dispersing shaft 801 has a movable groove 9 for the turbulence-dispersing blades 802 to deflect and swing. A support plate 901 is fixed to the inner wall of the movable groove 9. The support plate 901 is rotatably connected to the turbulence-dispersing blades 802 through a pin, so that the turbulence-dispersing blades 802 can deflect at an angle around the pin.

[0054] An adaptive adjustment component is provided on the disturbance shaft 801. The adaptive adjustment component includes a fixed seat 13, a buoyancy seat 14, a swing rod 15, a connecting block 151, a telescopic rod 152, and a slider 153. The fixed seat 13 is fixedly installed on the lower side of the disturbance shaft 801, and the buoyancy seat 14 is slidably sleeved on the upper part of the disturbance shaft 801. The buoyancy seat 14 can slide along the axial direction of the disturbance shaft 801 as the water level inside the water tank rises and falls. The fixed seat 13 and the buoyancy seat 14 are respectively hinged to the swing rod 15. The other ends of the two swing rods 15 are jointly hinged to the connecting block 151 to form a scissor linkage structure. The telescopic rod 152 is connected to the outside of the connecting block 151. The telescopic end of the telescopic rod 152 is fixed to the slider 153. The slider 153 is slidably engaged in the annular groove 601 on the inner side wall of the central ring 6.

[0055] When the water level inside the tank body 1 rises, the buoyancy seat 14 slides upward along the disturbance shaft 801 under the action of buoyancy, causing the two swing rods 15 to open like scissors, driving the connecting block 151 to undergo radial displacement. The telescopic rod 152 automatically extends and retracts according to the distance between the connecting block 151 and the central ring 6, driving the central ring 6 to slide upward along the inner wall of the tank body 1 via the slider 153. When the water level drops, the buoyancy seat 14 moves downward with the liquid level, and the scissor swing rods 15 retract in the opposite direction, driving the central ring 6 to move downward synchronously. Relying on the above linkage, the central ring 6 can always be kept in the actual middle position of the water body, regardless of the change in the water level of the tank. This realizes that cold water is distributed from the drain chamber of the central ring 6 to the middle layer of the tank, and the circulating heat exchange water is drawn from the middle layer from the inlet chamber of the central ring 6. This avoids low-temperature cold water directly rushing into the high-temperature storage area at the top or bottom of the tank, optimizes the internal temperature field distribution of the tank, stabilizes the heat pump inlet water temperature, and reduces the frequency of unit start-up and shutdown.

[0056] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the turbulence component is further equipped with an adjustment component. The adjustment component is driven by the pressure difference of the water flow inside the water supply pipe 2 to change the deflection angle of the turbulence blade 802, thereby switching the turbulence intensity. The adjustment component includes a slide plate 10, a connecting rod 1001 and a drive unit. The slide plate 10 is slidably disposed in the turbulence shaft 801 and can slide up and down along the axial direction of the turbulence shaft 801. The slide plate 10 and each turbulence blade 802 are hinged to the connecting rod 1001. When the slide plate 10 moves axially, the turbulence blade 802 is pushed and pulled by the connecting rod 1001 to realize the blade angle switching.

[0057] The drive unit includes a connecting plate 11, an elastic telescopic member 111, a connecting sleeve 112, and a force-bearing rod 113. The connecting plate 11 is fixedly disposed at the bottom of the connecting rod 1001. The elastic telescopic member 111 is disposed between the connecting plate 11 and the bottom end of the disturbance shaft 801, providing an elastic driving force for the slide plate 10 to return to its downward position. The connecting sleeve 112 is rotatably disposed on the outside of the connecting plate 11. The connecting sleeve 112 can rotate relative to the connecting plate 11 to avoid rotational interference caused by the rotation of the disturbance shaft 801. The force-bearing rod 113 is fixedly arranged vertically on the lower side of the connecting sleeve 112.

[0058] The water supply pipe 2 has a groove in its wall, and an elastic membrane 12 is embedded inside the groove. The bottom end of the force-bearing rod 113 abuts against the elastic membrane 12. A swing plate 121 is rotatably mounted on the inner wall of the water supply pipe 2 via a pin, and the inner side of the swing plate 121 abuts against the elastic membrane 12. When there is no water flow inside the water supply pipe 2, the swing plate 121 is not impacted by the water flow, and the elastic telescopic member 111 keeps the slide plate 10 at the lower limit position. The connecting rod 1001 pulls the turbulence blade 802 to maintain its tilted posture. The turbulence motor 8 drives the turbulence shaft 801 to rotate. The guide surfaces on both sides of the tilted plate turbulence blade 802 form a strong turbulence on the water body, which quickly eliminates the water temperature stratification inside the water tank and accelerates the water temperature equalization speed.

[0059] When the system starts water replenishment, cold water flows inside the water replenishment pipe 2. The water flow impacts the swing plate 121, causing it to deflect. The swing plate 121 squeezes the elastic membrane 12, causing it to deform and push the force rod 113 upward. The force rod 113 moves upward, driving the connecting sleeve 112 and the connecting plate 11 to move upward together, overcoming the elastic force of the elastic telescopic component 111 and pushing the slide plate 10 upward. The upward-moving slide plate 10 pulls the turbulence blades 802 to rotate around the pin shaft through each set of connecting rods 1001, so that the turbulence blades 802 switch to a horizontal arrangement. In the horizontal state, the turbulence blades 802 reduce the disturbance amplitude to the water body when rotating, retaining only a weak disturbance effect. This can avoid strong disturbance causing large-scale mixing of low-temperature cold water in the middle layer and high-temperature hot water in the top layer, preventing a sudden drop in outlet water temperature. At the same time, the weak disturbance can also prevent the water in the middle layer water replenishment area from becoming completely still and forming stubborn cold water stratification, preventing difficulties in water mixing after water replenishment.

[0060] After the water replenishment process is completed, the water flow inside the water replenishment pipe 2 disappears, and the swing plate 121 is no longer impacted by the water flow. The elastic telescopic component 111 releases elastic potential energy to drive the connecting plate 11 and the sliding plate 10 to reset downwards, causing the turbulence blade 802 to switch back to the tilted posture. The turbulence intensity is restored, and the residual temperature difference inside the water tank is quickly smoothed out. The entire angle switching process is entirely driven by the pressure difference of the water replenishment flow, and no additional sensors or electronic control components are required.

[0061] This invention also discloses a method for operating a circulating water tank in an air source water heater, comprising the following steps:

[0062] S1: When the user uses water, the water level in the water tank body 1 drops. Tap water enters the water tank body 1 through the water supply pipe 2. At the same time, the circulation pump starts and draws water from the water tank body 1 through the water outlet pipe 5. After being heated by the air source heat pump heat exchanger, the water flows back to the water tank body 1 through the return water pipe 4.

[0063] Subsequently, the turbulence motor 8 starts, driving the turbulence shaft 801 to rotate, and the turbulence blades 802 rotate with the turbulence shaft 801;

[0064] S2: When water flows through the water supply pipe 2, the water flow impacts the swing plate 121, the swing plate 121 rotates around the pin shaft, pushing the elastic membrane 12 to deform upward. The elastic membrane 12 pushes the force rod 113, and the force rod 113 drives the connecting plate 11 to move upward through the connecting sleeve 112. The connecting plate 11 compresses the elastic telescopic member 111 and pushes the slide plate 10 to slide upward along the disturbance shaft 801. When the slide plate 10 moves upward, it pulls each turbulence blade 802 to rotate around the pin shaft on the support plate 901 through the connecting rod 1001. The turbulence blade 802 gradually changes from an inclined state to a horizontal state.

[0065] When the horizontally positioned turbulence blade 802 rotates with the turbulence shaft 801, the area facing the water body decreases, and the turbulence force is reduced.

[0066] S3: As water replenishment proceeds, the water level in the tank body 1 gradually rises. The buoyancy seat 14 is subjected to buoyancy and slides upward along the disturbance shaft 801. The two swing rods 15 between the buoyancy seat 14 and the fixed seat 13 make scissor-like movements. The position of the connecting block 151 is automatically adjusted accordingly, always remaining in the middle of the water. When the position of the connecting block 151 changes, the telescopic rod 152 automatically extends and retracts to adapt to the change in distance between the connecting block 151 and the centering ring 6, so that the centering ring 6 is always in the middle of the water.

[0067] S4: When the water level in the water tank body 1 reaches the set height, the tap water stops replenishing, the water flow in the water supply pipe 2 disappears, the swing plate 121 is no longer impacted by the water flow, and resets under the action of gravity and elasticity. The elastic membrane 12 loses external force and returns to its original state. The elastic telescopic component 111 releases elastic potential energy, pushes the connecting plate 11 to move down, and drives the slide plate 10 to slide down and reset along the disturbance shaft 801. The slide plate 10 pulls the turbulence blade 802 to rotate through the connecting rod 1001. The turbulence blade 802 returns from the horizontal state to the inclined arrangement state.

[0068] S5: After the turbulence blade 802 returns to its tilted state, its frontal area increases as it rotates with the turbulence shaft 801, which strengthens the turbulence force on the water body and fully agitates the water in the water tank body 1, so that the cold water at the bottom and the hot water at the top are mixed and heated evenly, breaking the temperature gradient formed during water replenishment.

[0069] S6: When the water temperature in the water tank body 1 reaches the set temperature, the air source heat pump heat exchanger stops, the circulation pump stops, the turbulence motor 8 stops running, the turbulence blades 802 remain stationary, and the water tank body 1 maintains a uniform hot water state for user use.

[0070] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method for operating a circulating water tank for an air-source heat pump water heater according to claim 9, characterized in that, Includes the following steps: S1: When the user uses water, the water level in the water tank body (1) drops. Tap water enters the water tank body (1) through the water supply pipe (2). At the same time, the circulation pump starts and draws water from the water tank body (1) through the water outlet pipe (5). After being heated by the air source heat pump heat exchanger, the water flows back to the water tank body (1) through the return water pipe (4). Subsequently, the turbulence motor (8) starts, driving the turbulence shaft (801) to rotate, and the turbulence blades (802) rotate with the turbulence shaft (801); S2: When water flows through the water supply pipe (2), the water flow impacts the swing plate (121), the swing plate (121) rotates around the pin shaft, pushing the elastic membrane (12) to deform upward, the elastic membrane (12) pushes the force rod (113) on top, the force rod (113) drives the connecting plate (11) to move upward through the connecting sleeve (112), the connecting plate (11) compresses the elastic telescopic component (111) and pushes the slide plate (10) to slide upward along the disturbance shaft (801). When the slide plate (10) moves upward, it pulls each turbulence blade (802) around the pin shaft on the support plate (901) through the connecting rod (1001), and the turbulence blade (802) gradually changes from the inclined state to the horizontal state. When the horizontally positioned turbulence blade (802) rotates with the turbulence shaft (801), the area facing the water body decreases, and the turbulence force is reduced. S3: As water replenishment proceeds, the water level in the tank body (1) gradually rises. The buoyancy seat (14) is subjected to buoyancy and slides upward along the disturbance shaft (801). The two swing rods (15) between the buoyancy seat (14) and the fixed seat (13) make scissor-like movements. The position of the connecting block (151) is automatically adjusted accordingly and always remains in the middle of the water. When the position of the connecting block (151) changes, the telescopic rod (152) automatically extends and retracts to adapt to the change in distance between the connecting block (151) and the centering ring (6), so that the centering ring (6) is always in the middle of the water. S4: When the water level in the tank body (1) reaches the set height, the tap water stops replenishing, the water flow in the water supply pipe (2) disappears, the swing plate (121) is no longer impacted by the water flow, and resets under the action of gravity and elasticity. The elastic membrane (12) loses external force and returns to its original state. The elastic telescopic component (111) releases elastic potential energy, pushes the connecting plate (11) to move down, and drives the slide plate (10) to slide down along the disturbance shaft (801) to reset. The slide plate (10) pulls the turbulence blade (802) to rotate through the connecting rod (1001). The turbulence blade (802) returns from the horizontal state to the inclined arrangement state. S5: After the turbulence blade (802) returns to its tilted state, the area facing the flow increases as it rotates with the turbulence shaft (801), which strengthens the turbulence force on the water body and fully agitates the water in the tank body (1), so that the cold water at the bottom and the hot water at the top are mixed and heated evenly, breaking the temperature gradient formed during the water replenishment period. S6: When the water temperature in the water tank body (1) reaches the set temperature, the air source heat pump heat exchanger stops, the circulation pump stops, the turbulence motor (8) stops running, the turbulence blades (802) stop, and the water tank body (1) maintains a uniform hot water state for user use.
