[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] This application provides a refrigerator as an example; please refer to [link to example]. Figure 1 , Figure 1 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. The refrigerator 100 includes an air duct 110, a fan 120, a wind power generation component 130, and a load 140.

[0020] The fan 120 is used to drive the airflow in the duct 110; the wind power generation component 130 is installed in the duct 110 to convert wind energy into electrical energy to power the load 140 of the refrigerator 100.

[0021] It should be noted that the air duct 110 is the supply and return air duct of the refrigerator 100, and can be the refrigerator air duct, freezer air duct, or other air duct of the refrigerator 100. The fan 120 can be installed on the air duct, for example, at the air inlet 111 of the air duct. The two ends of the air duct 110 are connected to the refrigeration chamber and the storage chamber of the refrigerator 100, respectively. Driven by the fan 120, cold air in the refrigeration chamber is supplied to and returns to the storage chamber through the air duct 110 to achieve cooling of the storage chamber.

[0022] The refrigerator 100 provided in this application embodiment adds a wind power generation component 130 in the air duct 110. The wind power generation component 130 converts wind energy into electrical energy and uses the converted electrical energy to power the load 140, which can reduce wind power loss in the air duct 110 and improve the energy saving and environmental protection of the refrigerator 100.

[0023] In some embodiments, please refer to Figure 2 , Figure 2This is a schematic diagram of a wind turbine generator 131 installed in a wind duct 110 according to an embodiment of this application. The wind duct 150 power generation assembly includes multiple wind turbine generators 131, which are spaced apart in the wind duct 110. The wind turbine generators 131 are, for example, micro-generators and are installed on the inner wall of the wind duct 110. Preferably, the blades of the wind turbine generator 131 are made of lightweight and high-strength materials such as carbon fiber composites to reduce the blade's weight and improve its dynamic response capability; and the wind turbine generator 131 can be a permanent magnet generator, combined with direct drive technology and a high-efficiency gearbox. Furthermore, designers can optimize parameters such as the shape, surface, and angle of attack of the blades based on actual simulation results to improve the power generation efficiency of the wind turbine generator 131.

[0024] Optionally, the air duct 110 includes an air inlet 111 and an air outlet 112, and at least one wind turbine generator 131 is installed at the air inlet 111 and / or the air outlet 112. Due to the uneven distribution of airflow velocity and pressure at the air inlet 111 and the air outlet 112 of the air duct 110, eddies and separated flows are easily generated, resulting in significant wind power loss. By installing a wind turbine generator 131 at the air inlet 111 and / or the air outlet 112, wind power generation can be used to reduce wind power loss.

[0025] In some embodiments, the air duct 110 includes an installation section 113, on the inner wall of which at least one wind turbine 131 is disposed. Optionally, the installation section 113 is bent, contracted, or expanded; or the installation section 113 is a long straight strip, with the wind turbine 131 disposed in the middle of the installation section 113.

[0026] It should be noted that when the duct 110 has a bend, the airflow will generate vortices and separation flow in the bend, resulting in significant wind power loss. When the duct 110 has a contraction or expansion section, the variable cross-section will cause changes in airflow velocity and pressure, increasing frictional resistance and thus causing significant wind power loss. When the duct 110 has a long straight section, the frictional resistance generated by the long straight section will accumulate with increasing length, resulting in significant resistance in the middle section and causing wind power loss. Understandably, by installing a wind turbine 131 in the duct section 113, wind power generation can be used to mitigate wind power loss.

[0027] In some embodiments, please refer to Figure 3 , Figure 3This is another structural schematic diagram of the refrigerator 100 provided in this application embodiment. The refrigerator 100 also includes a damper 150, which is disposed in the air duct 110, and at least one of a plurality of wind turbine generators 131 is disposed on the damper 150. The damper 150 is used to control the airflow through the air duct 110 by adjusting the opening angle, thereby achieving temperature control of the storage compartment of the refrigerator 100. While the damper 150 obstructs airflow, it also causes significant wind power loss. By installing a wind turbine generator 131 on the damper 150, wind power can be converted into electrical energy for power supply, reducing the degree of wind power loss.

[0028] In some embodiments, the rotational speed and output power of the wind turbine 131 are adjustable. For example, the wind turbine 131 is equipped with an intelligent speed control device, which is adapted to adjust the rotational speed of the wind turbine 131 according to the wind speed, thereby preventing excessive load on the wind turbine 131 and causing damage. Optionally, the wind turbine 131 is equipped with a controller, which is adapted to acquire the environmental parameters inside the refrigerator 100 and the operating parameters of the refrigerator 100, so as to adaptively adjust the rotational speed and output power of the wind turbine 131 according to the actual situation.

[0029] In some embodiments, please refer to Figure 4 , Figure 4 This is another structural schematic diagram of the refrigerator 100 provided in this application embodiment. The wind power generation component 130 also includes an energy storage device 132, which includes an input terminal and an output terminal. The input terminal is electrically connected to the wind turbine generator 131, and the output terminal is electrically connected to the load 140. The energy storage device 132 is used to store the electrical energy converted by the wind turbine generator 131 and to supply power to the load 140. The energy storage device 132 can be a high-efficiency battery pack. Preferably, the battery management system configured inside the high-efficiency battery pack monitors parameters such as battery charge, temperature, voltage, and current in real time to ensure that the battery operates under safe and efficient conditions. Optionally, the high-efficiency battery pack is equipped with a controller, which is adapted to automatically adjust the charging current and discharging power of the battery according to the output power of the wind turbine generator 131, the power demand of the refrigerator 100, and the operating mode, so as to achieve reasonable distribution and efficient utilization of electrical energy. Optionally, the output terminal is also connected to the wind turbine 120, and the energy storage device 132 is also used to supply power to the wind turbine 120. In this way, energy waste can be reduced.

[0030] In some embodiments, please refer to Figure 5 , Figure 5This is another structural schematic diagram of the refrigerator 100 provided in this application embodiment. The refrigerator 100 also includes a backup power supply device 160, which is electrically connected to the load 140. When the amount of electricity stored in the energy storage component is lower than a preset threshold, the load 140 is powered by the backup power supply device. In this way, the stable operation of the load 140 can be guaranteed.

[0031] The load 140 is a low-power device inside the refrigerator 100. For example, the load 140 may include a lighting device adapted to illuminate the storage compartment of the refrigerator 100; or, the load 140 may also include a display device that can be used to display parameters such as temperature and humidity of the refrigerator 100 compartment.

[0032] The refrigerator 100 provided in this application embodiment adds a wind power generation component 130 in the air duct 110. The wind power generation component 130 converts wind energy into electrical energy and uses the converted electrical energy to power the load 140, which can reduce wind power loss in the air duct 110 and improve the energy saving and environmental protection of the refrigerator 100.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
