[0032] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that the terms "vertical", "horizontal", "above", "below", "upper side", "top surface" and "bottom surface" are all based on the corresponding view or the orientation in which the refrigerator is placed when it is in normal use.

[0034] Please see Figures 1-2 and Figure 5 This utility model provides a refrigerator fan base, which includes a mounting plate 3, a frame 1, multiple support feet 2 and multiple support pads 4.

[0035] The mounting plate 3 includes a mounting surface 31 on which a fan 9 can be mounted.

[0036] The frame 1 is coaxially arranged with the mounting plate 3. The diameter of the mounting plate 3 is smaller than the diameter of the frame 1. Along the thickness direction of the mounting plate 3, the outer edge of the frame 1 near the mounting surface 31 is provided with a flange 11 extending away from the mounting surface 31.

[0037] The support foot 2 is partially connected to the mounting plate 3 and the frame 1. Along the radial direction of the mounting plate 3, the support foot 2 extends to the side of the frame 1 away from the mounting plate 3.

[0038] Each of the multiple support pads 4 corresponds one-to-one with a multiple of the support feet 2. The support pads 4 are connected to the corresponding support feet 2. Along the radial direction of the mounting plate 3, the support feet 2 are located on the side of the frame 1 away from the mounting plate 3. Along the thickness direction of the mounting plate 3, the distance from the side of the support pad 4 away from the mounting surface 31 to the mounting surface 31 is greater than the distance from the side of the frame 1 away from the mounting surface 31 to the mounting surface 31.

[0039] Wherein, the outer edge of the frame 1 refers to the side of the frame 1 close to the mounting surface 31 and along the radial direction of the mounting plate 3, and the edge of the frame 1 away from the mounting plate 3.

[0040] The function of the mounting plate 3 is to provide a stable mounting platform for the fan 9, ensuring that the fan 9 can work normally. The design of the mounting surface 31 needs to take into account the size and installation requirements of the fan 9, so as to ensure that the fan 9 can be stably installed on the mounting surface 31. The mounting surface 31 is the top surface of the mounting plate 3 when the fan base 8 is in the installation state.

[0041] Specifically, for example, a mounting groove can be provided on the mounting surface 31, a mounting bearing can be installed in the mounting groove, and a rotor can be installed on the mounting bearing, with the fan 9 installed on the rotor.

[0042] The frame 1, the support foot 2, and the mounting plate 3 can be integrally formed. When the fan base 8 is installed on a mounting plane, the orthographic projection of the frame 1 and the mounting plate 3 on the mounting plane is concentric, and the mounting plate 3 is located inside the frame 1.

[0043] Compared to the method of connecting the frame 1 and the mounting plate 3 through a solid connection, in this embodiment, the frame 1 and the mounting plate 3 are connected by the support foot 2, which can save more materials and thus reduce the manufacturing cost of the fan base 8.

[0044] The function of the support feet 2 is to connect the mounting plate 3 and the frame 1, and to provide support for the entire fan base 8. The distribution and structural design of the support feet 2 need to take into account the stability and load-bearing capacity of the fan base 8. In this embodiment, part of the support feet 2 extends to the side of the frame 1 away from the mounting plate 3. This makes it easier for the support feet 2 to connect with the support pad 4, and ultimately allows the support pad 4 to be installed more stably in the corresponding position, thereby improving the stability of the fan base 8.

[0045] Each of the multiple support pads 4 corresponds one-to-one with a multiple of the support feet 2, and the support pads 4 are connected to the corresponding support feet 2. Along the radial direction of the mounting plate 3, the support feet 2 are located on the side of the frame 1 away from the mounting plate 3; along the thickness direction of the mounting plate 3, the distance from the side of the support pad 4 away from the mounting surface 31 to the mounting surface 31 is greater than the distance from the side of the frame 1 away from the mounting surface 31 to the mounting surface 31. Thus, when the fan base 8 is installed on the mounting plane, the support pads 4 can contact the mounting plane, while the frame 1 typically does not. This allows the entire fan base 8 to be supported by the support pads 4, thereby further improving the stability and vibration damping performance of the fan base 8.

[0046] Specifically, since the support pad 4 is connected to the support foot 2, when the fan base 8 is placed inside the refrigerator's air duct, the support pad 4 can act as a buffer, reducing the impact of vibrations generated by the fan 9 during operation on other components of the refrigerator. Simultaneously, the distance from the side of the support pad 4 away from the mounting surface 31 to the mounting surface 31 is greater than the distance from the side of the frame 1 away from the mounting surface 31 to the mounting surface 31. This ensures that the support pad 4 contacts the mounting surface first, providing better support and shock absorption.

[0047] Along the thickness direction of the mounting plate 3, the outer edge of the frame 1 near the mounting surface 31 is provided with a flange 11 extending away from the mounting surface 31. The flange 11 can effectively increase the minimum distance between the bottom of the fan blade 91 and the frame 1. After the refrigerator defrosts, the water vapor in the air duct is less likely to condense into ice between the fan blade 91 and the base.

[0048] Specifically, when the fan 9 is working, the fan blade 91 rotates on the mounting plate 3. Due to the design of the flange 11 of the frame 1, the space between the fan blade 91 and the frame 1 is increased, making it difficult for water vapor to condense into ice in this area, thereby ensuring the normal operation of the fan 9 and improving problems such as noise.

[0049] Based on the above design, this embodiment provides a flange 11 extending away from the mounting surface 31 on the outer edge of the frame 1 near the mounting surface 31. This effectively increases the minimum distance between the bottom of the fan blade 91 and the frame 1, thereby reducing the risk of ice condensing between the fan blade 91 and the base, and thus ensuring the normal operation of the fan 9.

[0050] In one possible implementation, please refer to Figures 1-3 and Figure 5The support foot 2 includes a connecting section 202 and a support section 201 that are radially connected to each other along the mounting plate 3. One end of the connecting section 202 is connected to the outer peripheral surface of the mounting plate 3, and the other end is connected to the inner peripheral surface of the frame 1. The support section 201 is connected to the corresponding support pad 4.

[0051] Wherein, the outer peripheral surface of the mounting plate 3 refers to the radial direction of the mounting plate 3, the side of the mounting plate 3 facing the frame 1, the inner peripheral surface of the frame 1 refers to the radial direction of the mounting plate 3, and the side of the frame 1 facing the mounting plate 3.

[0052] The connecting segment 202 can effectively connect the mounting plate 3 and the frame 1 together to form an integral structure. The design of the connecting segment 202 needs to take into account the size and shape of the mounting plate 3 and the frame 1 to ensure the firmness of the connection. For example, the connecting segment 202 can be connected to the mounting plate 3 and the frame 1 by welding, bolting, or other methods.

[0053] The support segment 201 is connected to the corresponding support pad 4, and also to the frame 1. The function of the support segment 201 is to provide a foundation for the support pad 4 and to transfer the supporting force of the support pad 4 to the entire fan base 8. The structural design of the support segment 201 needs to take into account the size and connection method of the support pad 4. In this embodiment, the connection method between the support segment 201 and the support pad 4 can be selected according to the specific structure of the support pad 4, such as using a slot connection or a bolt connection.

[0054] Therefore, the design of the connecting section 202 and the supporting section 201 of the supporting foot 2 enables the supporting foot 2 to provide a good connection and support between the mounting plate 3 and the frame 1, while also facilitating the installation and use of the supporting pad 4. Through this structural design, the stability and reliability of the fan base 8 are further improved.

[0055] Optionally, the connecting section 202 and the supporting section 201 can be integrally formed. This increases the strength between the connecting section 202 and the supporting section 201, thereby improving the durability of the fan base 8.

[0056] Optionally, please see again Figure 1Along the thickness direction of the mounting plate 3, the connecting section 202 near the mounting surface 31 includes a first plane 21, a first inclined plane 22, and a second plane 23. Along the direction from the mounting plate 3 to the frame 1, the first plane 21, the first inclined plane 22, and the second plane 23 are connected sequentially. The first plane 21 is connected to the mounting plate 3, and the second plane 23 is connected to the frame 1. The distance from the second plane 23 to the mounting surface 31 is greater than the distance from the first plane 21 to the mounting surface 31, i.e., the support section 201 is configured as a stepped structure. This increases the distance between the bottom of the fan blade 91 and the support foot 2, thereby further reducing the risk of ice condensation between the fan blade 91 and the base, and thus ensuring the normal operation of the fan 9.

[0057] In one possible implementation, please refer again. Figures 1-3 and Figure 5 The support section 201 is provided with a connection port 7, and the support pad 4 is connected to the connection port 7. The material of the support pad 4 includes an elastic material.

[0058] The design of the connecting port 7 provides a specific location and method for installing the support pad 4. Specifically, the connecting port 7 includes an interconnected mounting port 71 and a connecting notch 72. The width of the connecting notch 72 is smaller than the diameter of the mounting port 71, and the width of the connecting notch 72 is smaller than the diameter of the support pad 4. The diameter of the mounting port 71 is smaller than the diameter of the support pad 4. Since the support pad 4 is made of an elastic material, it is elastic. When it is necessary to install the support pad 4 in the connecting port 7, a portion of the support pad 4 can be directly pressed into the mounting port 71 through the connecting notch 72.

[0059] Since the diameter of the mounting opening 71 is smaller than the diameter of the support pad 4, the support pad 4 and the mounting opening 71 are interference-fitted, ensuring a firm connection between the support pad 4 and the connecting opening 7. Simultaneously, the elastic material support pad 4 can deform to adapt to the size of the connecting opening 7 during installation, ensuring a tight connection. Because the width of the connecting notch 72 is smaller than the diameter of the mounting opening 71, the connecting notch 72 prevents the support pad 4 from easily detaching from the mounting opening 71, thereby greatly improving the convenience and stability of installing the support pad 4 on the connecting opening 7.

[0060] Furthermore, since the material of the support pad 4 includes elastic materials, such as rubber, it has good shock absorption performance during use. When the fan 9 vibrates during operation, the elastic material support pad 4 can absorb and buffer the vibration, reducing the impact of vibration on the fan base 8 and other components of the refrigerator, thereby improving the operational stability and reliability of the fan 9.

[0061] Optionally, please see Figure 1 and Figure 4 The support pad 4 has a shock-absorbing protrusion 44 protruding from the side away from the mounting surface 31.

[0062] The material of the shock-absorbing protrusion 44 includes rubber. When the fan base 8 is installed on the mounting surface, the shock-absorbing protrusion 44 can directly contact the mounting surface. When the fan 9 vibrates during operation, the shock-absorbing protrusion 44 can reduce the vibration amplitude of the fan 9, thereby reducing the impact on the fan base 8 and the fan 9 itself, and thus improving the service life of the fan base 8 and the fan 9.

[0063] In one possible implementation, please refer again. Figure 1 and Figure 4 and Figure 5 The support pad 4 includes a connecting post 42. One end of the connecting post 42 is provided with a first support plate 41, and the other end of the connecting post 42 is provided with a second support plate 43. The diameters of the second support plate 43 and the first support plate 41 are both larger than the diameter of the connecting post 42. The connecting post 42 is installed in the connecting port 7.

[0064] Since the diameters of the second support plate 43 and the first support plate 41 are both larger than the diameter of the connecting post 42, the support pad 4 has a structure that is large at both ends and small in the middle. When the connecting post 42 is pressed into the connecting opening 7, the second support plate 43 and the first support plate 41 can further restrict the relative position between the connecting post 42 and the connecting opening 7, which can prevent the support pad 4 from coming out of the connecting opening 7 during installation and use, so that the support pad 4 can be more firmly connected to the support section 201.

[0065] Meanwhile, after the fan base 8 is installed on the mounting surface, the second support plate 43 or the first support plate 41 will come into contact with the mounting surface. Since the diameter of the second support plate 43 or the first support plate 41 is larger than the diameter of the connecting column 42, the contact area between the support pad 4 and the mounting surface can be increased, thereby improving the support capacity of the support pad 4.

[0066] Specifically, when the fan base 8 is placed inside the refrigerator's air duct, the first support plate 41 and the second support plate 43 can contact the surface of the air duct, evenly transmitting the weight and vibration of the fan 9 to the air duct. That is, the first support plate 41 and the second support plate 43 can play a role in buffering and dispersing force, improving the service life of the support pad 4, and giving the support pad 4 good stability and shock absorption performance, thus ensuring the normal operation of the fan base 8.

[0067] In one possible implementation, please refer again. Figure 1 and Figure 5 The fan base 8 also includes multiple brackets 5, one end of which is connected to the outer peripheral surface of the mounting plate 3, and the other end is connected to the inner peripheral surface of the frame 1.

[0068] The multiple brackets 5 can be integrally formed with the mounting plate 3 and the frame 1. By setting multiple brackets 5 between the frame 1 and the mounting plate 3, the structural strength of the fan base 8 can be increased, while reducing the amount of material used. Specifically, in this embodiment, the bracket design replaces the entire solid surface design, which can effectively reduce the amount of material used and lower the material cost of the parts.

[0069] In one possible implementation, please refer again. Figure 1 The multiple support feet 2 are evenly arranged, and the multiple brackets 5 are evenly arranged. Along the circumference of the mounting plate 3, the multiple support feet 2 and the multiple brackets 5 are arranged at intervals.

[0070] The number and distribution of the brackets 5 and the supporting feet 2 need to be designed according to the size and load-bearing capacity of the fan base 8. For example, there are three brackets 5 and three supporting feet 2. The three supporting feet 2 and the three brackets 5 are evenly distributed between the frame 1 and the mounting plate 3, and the multiple supporting feet 2 and multiple brackets 5 are arranged alternately, that is, one supporting foot 2 is located between two brackets 5, and one bracket 5 is located between two supporting feet 2. This evenly distributed design can make the structure of the fan base 8 more stable and the force on each part more even. When the fan 9 generates vibration and pressure during operation, the brackets 5 can distribute these forces to the entire fan base 8, reducing the situation of excessive local stress, thereby further improving the service life of the fan base 8.

[0071] Furthermore, the evenly distributed support feet 2 and bracket 5 in this embodiment ensure that the fan base 8 is less prone to tilting or wobbling during installation and use. When the fan 9 vibrates during operation, the support feet 2 and bracket 5 work together to distribute the vibration across the entire fan base 8, reducing the impact on the fan 9 and other components of the refrigerator.

[0072] Meanwhile, the staggered arrangement of the support feet 2 and the bracket 5 fully utilizes the space of the fan base 8, making its structure more compact. This design reduces the volume of the fan base 8 while ensuring its stability, thus enabling more efficient use of the refrigerator's internal space.

[0073] It can be seen that the design of multiple brackets 5 enables the fan base 8 to reduce material costs while ensuring structural strength, thereby improving the economy and practicality of the fan base 8. This results in the fan base 8 having good stability and structural rationality, providing strong support for the normal operation of the refrigerator.

[0074] In one possible implementation, please refer again. Figure 2 and Figure 5 Along the thickness direction of the mounting plate 3, the frame 1, the support foot 2 and the bracket 5 are provided with multiple ribs 6 on the side away from the mounting surface 31.

[0075] The side of the frame 1, the support leg 2, and the bracket 5 closest to the mounting surface 31 can be smoothly arranged, and the side of the frame 1, the support leg 2, and the bracket 5 away from the mounting surface 31 is provided with multiple ribs 6.

[0076] Specifically, the ribs 6 on the frame 1 can enhance the rigidity of the frame 1 and prevent the frame 1 from deforming during the operation of the fan 9; the ribs 6 on the support leg 2 can improve the load-bearing capacity of the support leg 2 and ensure that the support leg 2 can stably support the fan base 8; the ribs 6 on the bracket 5 can increase the bending and compressive strength of the bracket 5, so that the bracket 5 can better withstand the various forces generated during the operation of the fan 9.

[0077] The design of the ribs 6 needs to be optimized based on the specific shape and size of the frame 1, the support legs 2, and the bracket 5. For example, the number, height, and thickness of the ribs 6 need to be adjusted according to the actual situation to achieve the best structural strength. In this embodiment, by reasonably designing the parameters of the ribs 6, the structural strength of the frame 1, the support legs 2, and the bracket 5 can be improved without increasing material costs excessively.

[0078] It can be seen that the design of the frame 1, the support foot 2, and the multiple ribs 6 on the side of the bracket 5 away from the mounting surface 31 makes the structure of the fan base 8 more robust, providing a guarantee for the stable operation of the fan 9.

[0079] In one possible implementation, please refer again. Figure 2 and Figure 5 The side of the plurality of support feet 2 away from the mounting surface and the side of the frame 1 away from the mounting surface 31 are located on the same plane.

[0080] The sides of the multiple support feet 2 away from the mounting surface 31 are located on the same plane as the sides of the frame 1 away from the mounting surface 31, meaning the support feet 2 are flush with the frame 1. This design effectively reduces the thickness of the base, thereby reducing the overall thickness of the fan assembly and making the overall structure of the fan base 8 more compact.

[0081] When the fan 9 is installed inside the refrigerator's air duct, reducing the thickness of the fan base 8 can correspondingly reduce the thickness of the air duct. Furthermore, reducing the air duct thickness can increase the effective volume inside the refrigerator. For example, when the internal space of the refrigerator is limited, reducing the thickness of the air duct can free up more storage space, improving the refrigerator's practicality.

[0082] Meanwhile, the fact that the support foot 2 and the frame 1 are located on the same plane also improves the stability of the fan base 8. When the fan 9 vibrates during operation, the support foot 2 and the frame 1 can jointly bear the vibration, reducing the swaying of the fan base 8. This design allows the fan base 8 to reduce its thickness while ensuring stability, bringing more advantages to the design and use of the refrigerator.

[0083] In one possible implementation, please refer to Figure 5 and Figure 6 The present invention also provides a fan assembly, which includes the refrigerator fan base 8 described in this application and the fan 9 mounted on the mounting surface 31.

[0084] The unique design of the refrigerator fan base 8 provides a solid foundation for the installation and operation of the fan 9. Specifically, the mounting surface 31 on the mounting plate 3 provides a stable mounting platform for the fan 9, ensuring that the fan 9 can be firmly installed on the fan base 8. The design of the frame 1, the support feet 2, the support pads 4, and the bracket 5 gives the fan base 8 good stability, shock absorption performance, and structural strength, effectively protecting the fan 9 and reducing the vibration and noise generated during the operation of the fan 9.

[0085] When the fan 9 is installed on the mounting surface 31 of the fan base 8, the motor and other components of the fan 9 can be connected and fixed at specific positions on the mounting surface 31. During operation, the fan 9 generates airflow that is transmitted to various parts of the refrigerator through the air duct, achieving the circulation of cold air inside the refrigerator. The design of the fan base 8 ensures the stability of the fan 9 during operation, enabling the fan 9 to work continuously and efficiently.

[0086] In practical applications, the installation of the fan assembly needs to take into account the refrigerator's air duct structure and dimensions. The fan assembly needs to be matched with the air duct to ensure that the airflow can move smoothly within the duct. At the same time, the installation position and method of the fan assembly also need to be adjusted according to the specific design of the refrigerator to achieve the best cooling effect.

[0087] Since the side of the multiple support feet 2 in the fan assembly away from the mounting surface 31 is on the same plane as the side of the frame 1 away from the mounting surface 31, the thickness of the fan base 8 can be reduced, thereby reducing the space occupied by the fan assembly.

[0088] Since the outer edge of the frame 1 near the mounting surface 31 has a flange 11 extending away from the mounting surface 31, the flange 11 can effectively increase the minimum distance between the bottom of the fan blade 91 and the frame 1. Therefore, it is not easy for ice to condense between the fan blade 91 and the base, thereby reducing the adverse risk of ice formation between the fan blade 91 and the base.

[0089] Therefore, the fan assembly in this embodiment can provide a safe and stable guarantee for the refrigeration function of the refrigerator.

[0090] In one possible implementation, the present invention also provides a refrigerator, which includes the fan assembly described in this application.

[0091] The function of the fan assembly in the refrigerator is to circulate cold air within the refrigerator. A frost-free refrigerator requires a fan 9 to deliver the cold air generated by the refrigeration system to various parts of the refrigerator. In this embodiment, the refrigerator includes the fan assembly described in this application. The fan assembly has advantages such as increasing the gap between the fan blades 91 and the base, and reducing the overall thickness of the fan 9. These advantages are significant for improving the performance of the refrigerator.

[0092] Specifically, increasing the gap between the fan blade 91 and the base can prevent water vapor in the air duct from condensing into ice between the fan blade 91 and the base after the refrigerator defrosts, thereby reducing problems such as the fan 9 not starting and generating noise.

[0093] Reducing the overall thickness of the fan assembly can correspondingly reduce the thickness of the air duct, increasing the effective volume inside the refrigerator. For example, with the same external dimensions, using this fan assembly can result in a larger storage space and improve the refrigerator's practicality.

[0094] Furthermore, the stability and vibration damping performance of the fan assembly can reduce the vibration and noise generated during the operation of the fan 9, improving the user experience of the refrigerator. In practical applications, refrigerator users expect the refrigerator to operate quietly and stably, and the excellent performance of the fan assembly can meet this need.

[0095] Meanwhile, the structural strength and material cost control of the fan assembly also have a significant impact on the production cost and reliability of the refrigerator. By rationally designing the structure of the fan assembly and reducing the amount of material used, the production cost of the refrigerator can be reduced, while the high structural strength of the fan assembly can ensure its reliability during long-term use and reduce the frequency of maintenance and replacement.

[0096] In practical applications, the refrigerator fan base 8 and its related components have broad application prospects. As consumers demand higher performance and quality from refrigerators, this design, which increases effective refrigerator volume, reduces noise, and lowers costs, will be welcomed by the market. At the same time, this design also aligns with the development trend of energy conservation and environmental protection.

[0097] In summary, refrigerators equipped with the fan assembly described in this application can greatly enhance their market competitiveness.

[0098] The above are merely various embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
