[0040] Fans and water pumps are common components in industry for providing power for fluid transportation. For example, in gas water heating equipment, a fan for driving the flow of gas-phase fluid and a water pump for driving the flow of liquid-phase fluid are usually provided. However, fans and water pumps are usually installed independently, requiring a separate set of driving devices respectively, resulting in a relatively high overall cost, occupying a large installation space, and the fan and the water pump need to be installed separately, with low installation efficiency.

[0041] The present utility model provides a fan-water pump assembly 100, which can integrate the functions of a fan and a water pump, reduce costs, improve structural compactness, reduce volume, and save installation space.

[0042] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the fan-water pump assembly 100 includes a driving device 10, a first working element, and a second working element. The driving device 10 has an independent gas flow channel 101 and a liquid flow channel 102. The gas flow channel 101 has an air inlet 1011 and an air outlet 1012, and the liquid flow channel 102 has a liquid inlet 1021 and a liquid outlet 1022. The first working element is movably arranged in the gas flow channel 101 for driving the fluid in the gas flow channel 101 to flow from the air inlet 1011 to the air outlet 1012. The second working element is movably arranged in the liquid flow channel 102 for driving the fluid in the liquid flow channel 102 to flow from the liquid inlet 1021 to the liquid outlet 1022. The driving device 10 has a first output end 10a drivingly engaged with the first working element and a second output end 10b drivingly engaged with the second working element for driving the first working element and the second working element to move respectively.

[0043] In this embodiment, the driving device 10 outputs power through the first output end 10a and the second output end 10b respectively. Optionally, the first output end 10a and the second output end 10b are configured to output power independently of each other to drive the first working element and the second working element to move independently. The first working element is movably disposed in the gas flow channel 101. By driving the first working element to move through the first output end 10a, the first working element can then do work on the gas-phase fluid in the gas flow channel 101, so as to convert the mechanical energy output from the first output end 10a of the driving device 10 into the kinetic energy and potential energy of the fluid, and then drive the gas-phase fluid to flow from the air inlet 1011 to the air outlet 1012 at a preset flow rate, thereby realizing the function of a fan; wherein, the first working element includes, but is not limited to, doing work on the gas-phase fluid in the gas flow channel 101 by rotation, plunger movement, etc. Optionally, the first working element is a wind wheel 20 rotatably disposed in the air flow channel. The second working element is movably disposed in the liquid flow channel 102. By driving the second working element to move through the second output end 10b, the second working element can then do work on the liquid-phase fluid in the liquid flow channel 102, so as to convert the mechanical energy output from the second output end 10b of the driving device 10 into the kinetic energy and potential energy of the fluid mass, to drive the liquid-phase fluid to flow from the liquid inlet 1021 to the liquid outlet 1022 at a preset flow rate, thereby realizing the function of a water pump; wherein, the second working element includes, but is not limited to, doing work on the gas-phase fluid in the gas flow channel 101 by rotation, plunger movement, etc. Optionally, the second working element is a pump wheel 30 rotatably disposed in the liquid flow channel 102. Among them, the number of the air inlet 1011, the air outlet 1012, the liquid inlet 1021, and the liquid outlet 1022 can be one, two, or more. The number of the first working element and the second working element can be one, two, or more.

[0044] Such as Figure 6As shown in the figure, the fan and water pump assembly 100 can be applied to a gas water heating device 1000, where the gas water heating device 1000 includes, but is not limited to, a gas water heater, a gas heating furnace, etc. The gas water heating device 1000 includes a main body 200 and a fan and water pump assembly 100 installed on the main body 200. The main body 200 has a gas path system for the flow of gas (such as gas or high-temperature flue gas generated after combustion) and a water path system for the passage of liquid. The gas flow channel 101 of the fan and water pump assembly 100 can be communicated with the gas path system, and the liquid flow channel 102 of the fan and water pump assembly 100 can be communicated with the water path system. When the fan and water pump assembly 100 works, the first working element is driven by the driving device 10 to do work on the gas in the gas flow channel 101 to realize the fan function, and then the gas can be driven to flow along the gas path system. The second working element is driven by the driving device 10 to do work on the liquid in the liquid flow channel 102 to realize the water pump function, and then the liquid can be driven to flow along the water path system. Among them, the gas water heating device 1000 can be a forced-draft gas water heating device 1000 or a forced-exhaust gas water heating device 1000. In the forced-draft gas water heating device 1000, the air outlet 1012 of the gas flow channel 101 can be communicated with the inlet end of the gas path system to realize the blower function; in the forced-exhaust gas water heating device 1000, the air inlet 1011 of the gas flow channel 101 can be communicated with the outlet end of the gas path system to realize the exhaust fan function.

[0045] In the fan and water pump assembly 100 of the technical solution of the present utility model, by providing an independent gas flow channel 101 and a liquid flow channel 102 in the driving device 10, the transportation of gas-phase fluid and liquid-phase fluid can be carried out simultaneously. The driving device 10 drives the first working element to move through the first output end 10a, and then the first working element can do work on the gas-phase fluid in the gas flow channel 101 to convert the mechanical energy output from the first output end 10a of the driving device 10 into the kinetic energy and potential energy of the fluid, and then drive the gas-phase fluid to flow from the air inlet 1011 to the air outlet 1012 at a preset flow rate, thereby realizing the fan function; the second working element is driven to move through the second output end 10b, and then the second working element can do work on the liquid-phase fluid in the liquid flow channel 102 to convert the mechanical energy output from the second output end 10b of the driving device 10 into the kinetic energy and potential energy of the fluid to drive the liquid-phase fluid to flow from the liquid inlet 1021 to the liquid outlet 1022 at a preset flow rate, thereby realizing the water pump function. In this way, the fan function and the water pump function can be integrated into one. The first working element and the second working element share a set of driving device 10, which can reduce costs. And compared with the separately arranged fan and water pump, the overall structure of the fan and water pump assembly 100 is more compact, the integration degree is higher, the overall volume is smaller, and the installation space can be saved.

[0046] When the fan and water pump assembly 100 is applied to the gas water heating equipment 1000, only one set of driving devices 10 needs to be configured to achieve the functions of both the fan and the water pump, which can reduce the cost of the gas water heating equipment 1000; moreover, the integration degree of the fan and water pump assembly 100 is higher, the number of driving devices 10 is reduced, the internal installation space of the gas water heating equipment 1000 can be saved, which is beneficial to reducing the volume of the gas water heating equipment 1000 and making more installation space available inside the gas water heating equipment 1000 for installing other expansion function modules. And when assembling the gas water heating equipment 1000, only the fan and water pump assembly 100 needs to be installed on the main body at one time, which can simplify the installation steps and thus improve the assembly efficiency of the gas water heating equipment 1000.

[0047] In one embodiment, the first output end 10a and the second output end 10b are configured to output torque independently of each other. The first working element is configured as a wind wheel 20 driven to rotate by the first output end 10a, and the second working element is configured as a pump wheel 30 driven to rotate by the second output end 10b.

[0048] In this embodiment, when the driving device 10 operates, it generates power and outputs torque through the first output end 10a to transmit the power to the wind wheel 20, thereby driving the wind wheel 20 to rotate at a certain speed. When the wind wheel 20 rotates, it can do work on the gas-phase fluid in the gas flow channel 101 to drive the gas-phase fluid to flow from the air inlet 1011 to the air outlet 1012 at a preset flow rate, thus realizing the fan function; it outputs torque through the second output end 10b to transmit the power to the pump wheel 30, thereby driving the pump wheel 30 to rotate at a certain speed. When the pump wheel 30 rotates, it can do work on the liquid-phase fluid in the liquid flow channel 102 to drive the liquid-phase fluid to flow from the liquid inlet 1021 to the liquid outlet 1022 at a preset flow rate, thus realizing the water pump function. By rotating the wind wheel 20 and the pump wheel 30 to do work on the fluid, it has a high work efficiency, and at the same time makes the structural design of the driving device 10 simpler.

[0049] The first output end 10a and the second output end 10b are configured to be able to output torque independently of each other, that is, the torques output by the first output end 10a and the second output end 10b are independent of each other and not interfered with. For example, the first output end 10a and the second output end 10b can output torques of the same magnitude or different magnitudes; for another example, the first output end 10a and the second output end 10b can output torques simultaneously, or one of them can output torque while the other does not work. It can be understood that the torques output by the first output end 10a and the second output end 10b are independent of each other, enabling the wind turbine 20 and the pump impeller 30 to operate independently of each other. For example, the wind turbine 20 and the pump impeller 30 can rotate synchronously or asynchronously, and for another example, the rotational speeds of the wind turbine 20 and the pump impeller 30 can be the same or different; thus, it can better adapt to different working conditions.

[0050] In one embodiment, the rotational speed of the wind turbine 20 is n1, and the rotational speed of the pump impeller 30 is n2, where the ratio of n1 to n2 is a fixed constant. In this way, the speed ratio of the wind turbine 20 and the pump impeller 30 is always kept fixed to better adapt to a specific application scenario. Among them, the fixed constant can be set according to the actual application scenario requirements, for example, it can be 1, 2, 3, etc., and no specific limitation is made here.

[0051] Among them, the first output end 10a and the wind turbine 20 can be directly driven and connected, or the first output end 10a and the wind turbine 20 are indirectly driven and connected through a transmission structure; the second output end 10b and the pump impeller 30 can be directly driven and connected, or the second output end 10b and the pump impeller 30 are indirectly driven and connected through a transmission structure. Contact power transmission or non-contact power transmission can be adopted between the first output end 10a and the wind turbine 20. Contact power transmission or non-contact power transmission can be adopted between the second output end 10b and the pump impeller 30.

[0052] In one embodiment, power is transmitted between the second output end 10b and the pump impeller 30 through a non-contact transmission component. In this way, the second output end 10b of the driving device 10 and the pump impeller 30 can be separated, improving the sealing performance of the liquid flow channel 102. The non-contact transmission component includes but is not limited to magnetic coupling, electromagnetic induction transmission, capacitive coupling transmission, etc.

[0053] Optionally, the non-contact transmission component includes a first magnetic member provided at the second output end 10b and a second magnetic member provided at the pump impeller 30, and the first magnetic member and the second magnetic member are driven by magnetic coupling. When the second output end 10b rotates, it can drive the first magnetic member to rotate, and the first magnetic member drives the second magnetic member to rotate through magnetic force, thereby driving the pump impeller 30 to rotate. In this way, non-contact transmission between the second output shaft and the pump impeller 30 can be achieved.

[0054] Considering that the wind wheel 20 is larger and heavier than the pump wheel 30, optionally, the first output end 10a is directly drivingly connected to the wind wheel 20. In this way, the wind wheel 20 can be directly driven to rotate through the first output end 10a, and the power transmission can be carried out more stably, making the rotation of the wind wheel 20 more stable and reliable.

[0055] As Figure 4 shown, in one embodiment, the driving device 10 includes a driving motor 11. The driving motor 11 includes a stator 111, a first rotor 112, and a second rotor 113. The first rotor 112 defines a first output end 10a, and the second rotor 113 defines a second output end 10b. The stator 111 and the first rotor 112 jointly define a first magnetic circuit to drive the first rotor 112 to rotate, and the stator 111 and the second rotor 113 jointly define a second magnetic circuit to drive the second rotor 113 to rotate.

[0056] In this embodiment, the driving motor 11 is a dual-rotor motor. The two rotors of the dual-rotor motor are respectively drivingly connected to the wind wheel 20 and the pump wheel 30. In this way, only one set of electronic control system is needed to control the driving motor 11 to work, and the wind wheel 20 and the pump wheel 30 can be driven to rotate through the driving motor 11. The stator 111 and the first rotor 112 form a first magnetic circuit through an air gap. After the coil winding of the stator 111 is energized, the first rotor 112 can be driven to rotate through the magnetic field of the first magnetic circuit, and then the wind wheel 20 is driven to rotate by the first rotor 112. The stator 111 and the second rotor 113 form a second magnetic circuit through an air gap. After the coil winding of the stator 111 is energized, the second rotor 113 can be driven to rotate through the magnetic field of the second magnetic circuit, and then the pump wheel 30 is driven to rotate by the second rotor 113. The first rotor 112 and the second rotor 113 share a stator 111. Compared with a dual-stator dual-rotor motor, one stator 111 can be omitted, the overall structure is simpler, the cost is lower, and the volume is smaller.

[0057] In one embodiment, the stator 111 includes a stator core, and a first winding coil and a second winding coil wound around the stator core. The first winding coil is drivingly matched with the first rotor 112, and the second winding coil is drivingly matched with the second rotor 113. Among them, the first winding coil and the second winding coil can be respectively controlled by different circuits, and the independent driving of the first rotor 112 and the second rotor 113 can be realized to realize the independent rotation of the wind wheel 20 and the pump wheel 30. Optionally, the stator 111 further includes an insulation system coated on the surface of the stator core. The winding coil and the stator core can be separated by the insulation system to avoid scratching the winding coil or the risk of short circuit. Among them, the insulation system can be realized by spraying an insulating layer on the surface of the stator core, or by assembling an insulating skeleton outside the stator core.

[0058] Optionally, the first rotor 112 and the second rotor 113 are arranged radially with respect to the stator 111. For example, the drive motor 11 can adopt a radial flux dual-rotor motor. Alternatively, the first rotor 112 and the second rotor 113 are arranged axially with respect to the stator 111. For example, the drive motor 11 can adopt an axial flux dual-rotor motor.

[0059] As Figure 4 shown, in one embodiment, the stator 111 is arranged in a ring shape. The first rotor 112 surrounds the outer periphery of the stator 111, and the second rotor 113 is arranged in the inner cavity of the stator 111. In this embodiment, the first rotor 112 is an outer rotor rotatably sleeved on the outer periphery of the stator 111, and the second rotor 113 is an inner rotor rotatably arranged in the inner cavity of the stator 111. In this way, the first rotor 112 and the second rotor 113 are arranged radially with respect to the stator 111. The overall arrangement structure is simple, which is beneficial to reducing the axial dimension of the drive device 10, and further reducing the volume of the fan and water pump assembly 100.

[0060] As Figure 4 shown, in one embodiment, the drive assembly further includes a shielding cover 115. The stator 111 is sleeved on the outer periphery of the shielding cover 115. The first rotor 112 is sleeved on the outer periphery of the stator 111 and is rotatably connected to the shielding cover 115. The second rotor 113 is rotatably installed in the shielding cover 115. In this embodiment, the shielding cover 115 can serve as an installation carrier for the stator 111, the first rotor 112, and the second rotor 113, facilitating the installation of the three. Moreover, by providing the shielding cover 115, the second rotor 113 can be separated from the stator 111, playing a role of dry-wet isolation to prevent the water in the liquid flow channel 102 from entering the stator 111, ensuring the safety of the drive device 10. The stator 111 and the shielding cover 115 can be fixed by potting (such as potting epoxy resin material) or BMC injection molding.

[0061] In one embodiment, the shielding cover 115 is provided with a bearing 117. The first rotor 112 includes a rotor housing 1121, a first magnetic ring 1123, and a first rotating shaft 1122. The rotor housing 1121 is sleeved on the periphery of the stator 111. The first magnetic ring 1123 is fixed on the inner peripheral surface of the rotor housing 1121 and is disposed opposite to the stator 111. One end of the first rotating shaft 1122 is connected to the bearing 117, and the other end is connected to the rotor housing 1121. The wind wheel 20 is connected to the rotor housing 1121. In this embodiment, the first magnetic ring 1123 can be fixed to the inner peripheral surface of the rotor housing 1121 by means of gluing or connection with fasteners. One end of the first rotating shaft 1122 is connected to the bearing 117 in the first accommodating cavity, and the other end of the first rotating shaft 1122 can be connected and fixed to the rotor housing 1121 by means of connection with fasteners or interference fit. The bearing 117 can stably support the first rotor 112 to ensure the stability of the rotation of the first rotor 112. The wind wheel 20 and the rotor housing 1121 can be integrally formed or can be a split structure and then assembled and fixed.

[0062] In one embodiment, the driving device 10 further includes a fixed shaft 116. The fixed shaft 116 is connected to the shielding cover 115. The second rotor 113 includes a shaft sleeve 1131, a second rotating shaft 1132, and a second magnetic ring 1133 that are sequentially sleeved on the periphery of the fixed shaft 116 from the inside to the outside.

That is, the pump housing 13 has an opening facing the driving motor 11. When the pump housing 13 and the driving motor 11 are assembled in place, the end face of the driving motor 11 can act as a cover plate of the pump housing 13 to cover the opening of the pump housing 13, so that the cover plate of the pump housing 13 can be omitted, which is beneficial to saving materials, reducing costs, and reducing the volume of the fan and water pump assembly 100. A sealing structure is provided at the connection part between the pump housing 13 and the driving motor 11 to ensure the sealing performance of the liquid flow channel 102.

That is, the volute 12 has an opening toward the drive motor 11. When the volute 12 and the drive motor 11 are assembled in place, the end surface of the drive motor 11 can play the role of a cover plate of the volute 12 to cover the opening of the volute 12, so that the cover plate of the volute 12 can be omitted, which is conducive to saving materials, reducing costs, and reducing the volume of the fan water pump assembly 100. Optionally, a sealing structure is provided at the connection between the volute 12 and the drive motor 11.

[0065] like Figure 2 and Figure 4 As shown, in one embodiment, the housing 114 includes an end plate 1141 and a housing body 1142 disposed on one side of the end plate 1141, the end plate 1141 protrudes from the outer peripheral surface of the housing body 1142, the volute 12 and the end plate 1141 enclose a gas flow channel 101, and the pump housing 13 is disposed on the side of the housing body 1142 away from the end plate 1141, and the side of the volute 12 away from the end plate 1141 is provided with an air inlet 1011, and the surrounding side of the volute 12 is provided with an air outlet 1012. Optionally, the end plate 1141 and the housing body 1142 are integrally formed, for example, the end plate 1141 and the housing body 1142 can be integrally formed by injection molding. Optionally, a convex rib 1143 is provided on the side of the end plate 1141 facing the housing body 1142, and the convex rib 1143 can play a structural reinforcement role, and is also conducive to heat dissipation of the drive device 10.

[0066] Optionally, the wind wheel 20 is a centrifugal wind wheel 20, which can provide a relatively large air volume and wind force with lower energy consumption, is more energy-saving, and has a stable structure and generates less noise. Optionally, the wind wheel 20 includes at least two layers of impellers arranged along the axial direction. The wind wheel 20 uses at least two layers of impellers, which is conducive to improving aerodynamic performance, reducing noise, and improving work efficiency. Optionally, the wind wheel 20 uses a centrifugal wind wheel 20 with at least two layers of impellers.

[0067] In another embodiment, the first working element is configured as a wind wheel 20 driven to rotate by the first output end 10a, and the second working element is configured as a pump wheel 30 driven to rotate by the second output end 10b; the first output end 10a and the second output end 10b are configured to synchronously output torque so that the wind wheel 20 and the pump wheel 30 rotate synchronously. In this way, when the fan-water pump assembly 100 is running, the driving device 10 can simultaneously drive the wind wheel 20 and the pump wheel 30 to rotate at the same speed, so as to realize the fan and water pump functions at the same time.

[0068] like Figure 5As shown, in a specific embodiment, the driving device 10 includes a rotor 110, a stator 111 and an output shaft 118. The rotor 110 is sleeved around the output shaft 118 and can drive the output shaft 118 to rotate together. Both ends of the output shaft 118 respectively form a first output end 10a and a second output end 10b. The wind wheel 20 and the pump wheel 30 are respectively connected to both ends of the output shaft 118. The stator 111 is sleeved around the rotor 110 and forms a magnetic circuit with the rotor 110 to drive the rotor 110 to rotate.

[0069] In this embodiment, the driving device 10 may include a driving motor 11, and a volute 12 and a pump housing 13 respectively arranged at both ends of the driving motor 11. Among them, the driving motor 11 includes a housing 114, a rotor 110, a stator 111 and an output shaft 118. The stator 111 is fixed in the housing 114. For example, the stator 111 can be assembled in the cavity of the housing 114, or the stator 111 can be integrally plastic-coated on the wall of the housing 114. The stator 111 may include a stator core and a winding coil arranged on the stator core. The winding coil is energized to drive the rotor 110 to rotate. Optionally, the stator 111 further includes an insulation system coated on the surface of the stator core. Through the insulation system, the winding coil can be separated from the stator core to avoid scratching the winding coil or the risk of short circuit. Among them, the insulation system can be realized by spraying an insulating layer on the surface of the stator core, or by assembling an insulating skeleton outside the stator core. The rotor 110 is accommodated in the inner cavity of the stator 111. The output shaft 118 passes through the central position of the rotor 110. Both ends of the output shaft 118 respectively pass out of both sides of the housing 114. One end of the output shaft 118 close to the volute 12 forms a first output end 10a to connect to the wind wheel 20, and one end of the output shaft 118 close to the pump housing 13 forms a second output end 10b to connect to the pump wheel 30. When the coil winding of the stator 111 is energized, it can drive the rotor 110 to rotate. The rotation of the rotor 110 can drive the output shaft 118 to rotate together, so as to drive the wind wheel 20 and the pump wheel 30 to rotate synchronously through the output shaft 118. At this time, the wind wheel 20 and the pump wheel 30 can rotate simultaneously, in the same direction and at the same speed.
