[0059] The following will be described in combination with Figures 1 to 16 The fan assembly 4, the air duct structure and the refrigeration equipment of the present application are described. The fan assembly 4 in the present application is mainly used to guide the flow of air in the refrigeration equipment, and the fan assembly 4 is provided in the air duct structure. The refrigeration equipment in the present application is applied to a refrigerator, but it should be understood that the refrigeration equipment of the present application can also be applied to a freezer or any other suitable equipment.

[0060] In one embodiment of the present application, as Figures 1 to 7 shown, the fan assembly 4 is applied to a refrigeration equipment, and the fan assembly 4 comprises a housing 41 and a fan 42. The housing 41 is formed with a fan air duct, and the housing 41 is formed with a drain port 411, a fan air inlet 412 and a plurality of fan air outlets 413. The drain port 411, the fan air inlet 412 and the plurality of fan air outlets 413 are in communication with the fan air duct, and the plurality of fan air outlets 413 are symmetrically arranged on both sides of the fan air inlet 412. The fan 42 is arranged at the fan air inlet 412, and the drain port 411 is located below the fan 42. The fan 42 is configured to guide the air in the refrigeration equipment from the fan air inlet 412 to the plurality of fan air outlets 413.

[0061] In the present embodiment, the position of the drain port 411 is intentionally arranged below the fan 42, so that even if condensate water is generated, it can naturally fall and be smoothly discharged. The plurality of fan air outlets 413 are generally symmetrically distributed on both sides of the fan air inlet 412, forming an balanced air output layout. The fan 42 is mainly used to drive air flow, which sucks the air inside the refrigeration equipment from the fan air inlet 412, then accelerates and pressurizes through the fan air duct, and finally uniformly discharges from the plurality of fan air outlets 413. This air flow mode helps to achieve rapid cooling inside the refrigeration equipment and maintain uniform temperature distribution.

[0062] When the refrigeration device starts to work, the fan assembly 4 also starts to work. After receiving the start signal, the fan 42 motor starts to rotate, driving the fan 42 blades to rotate rapidly. At this time, the fan air inlet 412 starts to suck the air inside the refrigeration device. With the rotation of the fan 42 blades, the air inside the refrigeration device is continuously sucked into the fan air inlet 412. The air accelerated and pressurized by the fan 42 is finally uniformly discharged from the plurality of fan air outlets 413. These air outlets are symmetrically distributed on both sides of the fan air inlet 412, ensuring that the air can be uniformly distributed to every corner of the refrigeration device. During the whole process, since the refrigeration device may generate some condensate water during operation, if the water is not discharged in time, it may cause damage to the device. The drain port 411 can naturally receive and discharge the accumulated water, ensuring the long-term stable operation of the fan assembly 4.

[0063] The fan assembly 4 provided by the embodiment is internally formed with a fan air duct, which is in communication with the drain port 411, the fan air inlet 412 and the plurality of fan air outlets 413. This ensures that the air can be smoothly sucked from the fan air inlet 412, and then uniformly discharged from the plurality of fan air outlets 413 after being acted on by the fan 42. The plurality of fan air outlets 413 are symmetrically arranged on both sides of the fan air inlet 412. This layout not only looks beautiful, but also helps to realize the uniformity and efficiency of air flow, thereby improving the heat exchange efficiency and air circulation efficiency. The drain port 411 is located below the fan 42, which helps to discharge the condensate water generated during the refrigeration process in time, preventing the water from accumulating in the shell 41 to cause dampness and corrosion problems.

[0064] In some embodiments, as shown in Figures 3 to 7 The shell 41 includes a first shell 414 and a second shell 415, and the first shell 414 and / or the second shell 415 is / are provided with a recess 416. The first shell 414 and the second shell 415 are butted to form the fan air duct through the recess 416. The drain port 411, the fan air inlet 412 and the plurality of fan air outlets 413 are arranged on the first shell 414 and / or the second shell 415.

[0065] In this embodiment, the first shell 414 and the second shell 415 are each provided with a recess 416, and the recesses 416 in the first shell 414 and the second shell 415 form a fan air duct in a butt joint manner, which is used for the flow of air. Since the drain port 411, the fan air inlet 412, and the plurality of fan air outlets 413 can be provided on the first shell 414 and / or the second shell 415, for example, the drain port 411, the fan air inlet 412, and the plurality of fan air outlets 413 can be provided on the first shell 414 or the second shell 415, or a part is provided on the first shell 414 and the other part is provided on the second shell 415, thus providing greater flexibility to optimize the positions and sizes of these openings. This helps to ensure that the fan assembly 4 can adapt to different installation environments and refrigeration needs.

[0066] The fan assembly 4 in this embodiment, by means of the double shell 41 and the configuration of the drain port 411, the fan air inlet 412, and the plurality of fan air outlets 413, facilitates maintenance and repair, improves the overall performance and reliability of the entire fan assembly 4, and enhances the adaptability and expandability of the fan assembly 4.

[0067] In some embodiments, as shown in Figures 3 to 7 The shell 41 further includes an air duct filler. The air duct filler is arranged in the recess 416, and the air duct filler cooperates with the side wall of the recess 416 to form the fan air duct.

[0068] In this embodiment, the air duct filler can be made of expanded polystyrene (EPS), which has good thermal insulation performance and helps to reduce energy loss; at the same time, it also has excellent sound insulation and shock absorption performance, which can reduce the noise and vibration when the fan 42 is running. In addition, EPS foam is easy to process and shape, which is convenient for adapting to different shapes and sizes of air duct requirements. Since the air duct filler optimizes the structure of the air duct, reduces air leakage and energy loss, it helps to improve the energy efficiency of the fan assembly 4.

[0069] Compared with the air duct directly formed by the shell 41, by setting the air duct filler in the shell 41 to optimize the structure of the air duct, the structural strength and stability can be enhanced.

[0070] In some embodiments, as shown in Figure 6 and Figure 7 The fan air inlet 412 is provided on the first shell 414, and the fan assembly 4 further includes a condensate water absorption member 43 connected to the first shell 414, and the condensate water absorption member 43 is located below the fan air inlet 412.

[0071] Specifically, the condensed water absorption member 43 is used to absorb and store the moisture dripped from the refrigeration system or other components that can generate condensed water. In the fan assembly 4, the condensed water absorption member 43 is connected to the first housing 414 and located below the fan air inlet 412 to avoid the condensed water from gathering on the first housing 414, thereby avoiding the potential moisture from adversely affecting the performance and lifespan of the fan 42. Meanwhile, by absorbing the condensed water, the condensed water absorption member 43 can also keep the first housing 414 and the fan air inlet 412 dry and clean.

[0072] In this embodiment, the condensed water blocking sponge is selected as the material of the condensed water absorption member 43. The sponge has excellent water absorption and can quickly absorb and store a large amount of condensed water. At the same time, the sponge is soft and has a certain elasticity, which can adapt to different shapes and sizes of installation space.

[0073] In one specific embodiment, as shown in Figures 3 to 7 The plurality of fan air outlets 413 includes a first fan air outlet 4131 and a second fan air outlet 4132, and the fan air duct includes a first fan air duct 417 and a second fan air duct 418. The first fan air duct 417 and the second fan air duct 418 are symmetrically formed in the housing 41, the first fan air duct 417 communicates with the second fan air duct 418, the fan air inlet 412 is located between the first fan air duct 417 and the second fan air duct 418, the fan air inlet 412 communicates with the first fan air duct 417 and the second fan air duct 418, the first fan air duct 417 communicates with the first fan air outlet 4131, and the second fan air duct 418 communicates with the second fan air outlet 4132, so that the fan 42 guides the air in the refrigeration equipment from the fan air inlet 412 to the first fan air outlet 4131 and the second fan air outlet 4132.

[0074] In this embodiment, the fan air inlet 412 is located on the first housing 414, and the symmetrically arranged first fan air outlet 4131 and the second fan air outlet 4132 not only have an aesthetic appearance, but also help to achieve uniformity of air flow. The first fan air duct 417 and the second fan air duct 418 are in communication in the housing 41, and the fan air inlet 412 is located between them and communicates with both of them.

[0075] The first fan air duct 417 is located on the left side of the entire fan assembly 4, and the second fan air duct 418 is located on the right side of the entire fan assembly 4. The first fan air outlet 4131 is located at the bottom of the left side of the entire fan assembly 4, and the second fan air outlet 4132 is located at the bottom of the right side of the entire fan assembly 4.

[0076] When the fan 42 is running, air is sucked from the fan air inlet 412 and enters the first fan air duct 417 and the second fan air duct 418 respectively, and then is discharged from the first fan air outlet 4131 and the second fan air outlet 4132 respectively. The fan air duct layout and air outlet configuration of the embodiment realize the efficiency and uniformity of air flow.

[0077] In some embodiments, as shown in Figures 4 to 6 The fan assembly 4 further includes a sealing piece 44. The sealing piece 44 is formed with a notch matched with the shape of the fan air outlet 413, and is connected between the fan air outlet 413 and the back plate air duct assembly 5 of the refrigeration equipment, so as to communicate the fan air outlet 413 and the back plate air duct assembly 5 through the notch, improve the tightness of the sealing, and effectively prevent air leakage, thereby improving the air supply efficiency of the fan assembly 4.

[0078] In the embodiment, the sealing piece 44 can adopt a sealing sponge. The sponge has good elasticity and compressibility, and can adapt to fan outlets and back plate air duct assemblies 5 of different shapes and sizes, ensuring the tightness of the sealing. At the same time, the sponge also has certain sound insulation and shock absorption performance, which can reduce the noise and vibration when the fan 42 is running, and improve the user experience.

[0079] Since the sealing piece 44 has good elasticity and detachability, when maintenance or replacement is needed, the user can conveniently remove it from between the fan air outlet 413 and the back plate air duct assembly 5, and perform necessary cleaning or replacement operation.

[0080] In some embodiments, as shown in Figure 8 and Figure 9 The fan assembly 4 further includes at least one of the following: a wire clip 45 connected to the housing 41 for fixing the wires of the fan assembly 4; and a wire slot 46 formed on the housing 41 for accommodating and guiding the wires of the fan assembly 4.

[0081] In the embodiment, the wires are fixed by the wire clip 45, which can make the wiring inside the fan assembly 4 more neat and orderly. This not only improves the aesthetics of the fan assembly 4, but also helps users to find the required wires more quickly when maintaining and inspecting. The wire clip 45, by fixing the wires, can also enhance the structural strength of the fan assembly 4 to some extent. When the wires are pulled by external force, the wire clip 45 can effectively absorb and disperse these forces, protecting the wires and the fan assembly 4 from damage.

[0082] By setting the wire slot 46, it can be ensured that the electric wire is arranged in a predetermined path inside the fan assembly 4, avoiding the crossing and winding of the electric wire, improving the efficiency and reliability of the wiring. At the same time, the use of the wire slot 46 also makes it easier for the user to find and operate the electric wire when maintaining and checking the fan assembly 4. The user only needs to search along the path of the wire slot 46 to quickly locate the position of the required electric wire.

[0083] In some embodiments, as shown in Figure 8 and Figure 10 The fan assembly 4 further comprises a first fixed side plate 47 and a second fixed side plate 48 connected to the refrigeration equipment; and the two sides of the shell 41 are connected to the first fixed side plate 47 and the second fixed side plate 48, respectively.

[0084] Specifically, the first fixed side plate 47 and the second fixed side plate 48 are connected to the refrigeration equipment, and they are separated by a certain distance to provide stable support for the shell 41. One end of the shell 41 is provided with a protrusion 4152, and the other end is provided with a plug-in interface 4151, so that the shell 41 can be conveniently inserted into the first fixed side plate 47 and the second fixed side plate 48. The user only needs to insert the protrusion 4152 end of the shell 41 into the first fixed side plate 47, and then insert a part of the second fixed side plate 48 into the plug-in interface 4151 of the shell 41, to complete the fixation of the shell 41.

[0085] In order to ensure the connection strength of the fan assembly 4, one side of the shell 41 can also be fixed in the refrigeration equipment by screws. This additional fixing method further enhances the stability of the fan assembly 4, making it more reliable during operation. At the same time, the screw fixation also makes it more convenient to disassemble and reinstall the fan assembly 4 when it needs to be repaired or replaced.

[0086] The application also provides a wind channel structure, as shown in Figures 11 to 16 The wind channel structure comprises the return air inlet assembly 2, the evaporator assembly 3, the fan assembly 4, the back plate wind channel assembly 5, and the condensate water collection assembly 1. The evaporator assembly 3 is arranged on the condensate water collection assembly 1, and the return air inlet assembly 2 is communicated with the back plate wind channel assembly 5 through the evaporator assembly 3 and the fan assembly 4, so as to guide the air by the fan assembly 4, so that the air enters from the return air inlet assembly 2, is cooled by the evaporator assembly 3, and is discharged from the back plate wind channel assembly 5 through the fan assembly 4.

[0087] In this embodiment, the return air inlet assembly 2 serves as the entrance of the air inlet duct structure, which is used to introduce the air in the refrigeration liner 7 into the air duct. One end of the return air inlet assembly 2 extends to the inside of the refrigeration liner 7, and the other end is connected with the evaporator assembly 3. The return air inlet assembly 2 ensures that the air can be smoothly drawn out of the refrigeration liner 7 and directed to the next stage of the cooling process. The evaporator assembly 3 transfers the heat in the air to the refrigerant through the principle of heat exchange, thereby achieving the cooling of the air. The evaporator assembly 3 is arranged above the condensate water collection assembly 1, so as to facilitate the collection and discharge of the condensate water. The evaporator assembly 3 is fixed outside the refrigeration liner 7 by the evaporator fixing buckle on the condensate water collection assembly 1. The fan assembly 4 is located between the evaporator assembly 3 and the back plate air duct assembly 5. The first fixed side plate 47 and the second fixed side plate 48 are arranged outside the refrigeration liner 7, and the evaporator assembly 3, the return air inlet assembly 2 and the condensate water collection assembly 1 are fixed outside the refrigeration liner 7 as a whole by the first fixed side plate 47 and the second fixed side plate 48. The fan assembly 4 provides power to drive the circulation of air, so that the cooled air can be effectively discharged from the back plate air duct assembly 5, while new air is sucked in for cooling. The back plate air duct assembly 5 serves as the outlet passage of the air, which discharges the cooled air out of the refrigeration liner 7, while also providing a circulating path for the air. The back plate air duct assembly 5 is usually fixed to the back or side of the refrigeration liner 7 by means of a hanging buckle and screws, so as to facilitate the discharge and circulation of air. The condensate water collection assembly 1 collects the condensate water generated by the evaporator assembly 3 during operation, preventing the condensate water from accumulating and possibly causing damage to the equipment. The condensate water collection assembly 1 is located below the evaporator assembly 3, ensuring that the condensate water can flow in smoothly and be collected. The specific structure of the condensate water collection assembly 1 can be referred to in the above embodiment, which will not be described here. The air duct structure as a whole is arranged on the refrigeration liner 7 of the refrigeration equipment, and cooperates with the degerming assembly 9, the refrigeration display screen assembly 8 and the like inside the refrigeration liner 7.

[0088] In the working process, the air in the refrigeration liner 7 is sucked into the air duct structure through the return air inlet assembly 2. The sucked air enters the evaporator assembly 3. The evaporator assembly 3 transfers the heat in the air to the refrigerant through the principle of heat exchange, thereby achieving the cooling of the air. In this process, the evaporator assembly 3 will generate condensate water, which is collected in the condensate water collection assembly 1. The cooled air is driven by the fan assembly 4 and discharged through the back plate air duct assembly 5. The fan assembly 4 provides power to enable the air to circulate smoothly in the air duct structure. The back plate air duct assembly 5 serves as the outlet passage of the air, ensuring that the cooled air can be evenly distributed into the refrigeration liner 7. The discharged air enters the refrigeration liner 7 again and mixes with other air in the refrigeration liner 7. As the refrigeration equipment continues to operate, the air is continuously sucked in, cooled, discharged and circulated, thereby achieving uniform cooling of the air in the refrigeration liner 7.

[0089] The air duct structure provided by the embodiments of the present application adopts a fan assembly, which ensures that air can be smoothly sucked from the fan air inlet, uniformly discharged from the multiple fan air outlets after the action of the fan. The multiple fan air outlets are symmetrically arranged on the two sides of the fan air inlet. This layout is not only beautiful, but also helps to achieve the uniformity and efficiency of air flow, thereby improving the heat exchange efficiency and air circulation efficiency. At the same time, the drain port is located below the fan, which helps to timely drain the condensate water generated during the refrigeration process, preventing water from accumulating in the shell to cause dampness and corrosion problems.

[0090] The embodiments of the present application also provide a refrigeration equipment, which can be a refrigerator, a freezer or other equipment, such as Figures 1 to 16 As shown in the figure, the refrigeration equipment includes a cabinet 6 and an air duct structure. The cabinet 6 forms a storage space inside; the air duct structure is arranged in the storage space.

[0091] In the embodiments, the refrigerator is an embedded refrigerator. The embedded refrigerator realizes seamless docking with the surrounding environment by embedding the refrigerator body into the cabinet or wall of the kitchen. The cabinet 6 serves as the shell of the refrigeration equipment and provides necessary protection and support for the storage space. The cabinet 6 forms a spacious storage space inside, which is used to store various items that need to be refrigerated or frozen. The refrigeration liner 7 is located in the storage space inside the cabinet 6. The refrigeration liner 7 provides a relatively closed refrigeration environment for the storage space, ensuring that the items therein can be kept within the required temperature range. The refrigeration liner 7 is usually made of materials with good thermal insulation performance, such as foamed plastic or vacuum insulated panels, to reduce heat transfer and loss. The air duct structure is arranged above the refrigeration liner 7 and is closely connected with the refrigeration liner 7. The air duct structure is responsible for guiding the circulation of air inside the refrigeration equipment and cooling the air through the evaporator assembly 3. The evaporator assembly 3, the return air inlet assembly 2 and the condensate water collection assembly 1 are fixed as a whole outside the refrigeration liner 7 by the first fixed side plate 47 and the second fixed side plate 48. The specific structure of the air duct structure can be referred to the above embodiments, which will not be described here. The air duct structure is usually composed of multiple components such as the return air inlet assembly 2, the evaporator assembly 3, the fan assembly 4, the back plate air duct assembly 5 and the condensate water collection assembly 1. These components work together to realize the cooling and circulation of air.

[0092] When the refrigeration equipment starts, the fan assembly 4 starts to work and drives the circulation of air in the air duct structure. The return air inlet assembly 2 sucks the air in the refrigeration liner 7 into the air duct structure, which is then cooled by the evaporator assembly 3. The cooled air is discharged by the fan assembly 4 and uniformly distributed into the refrigeration liner 7 through the back plate air duct assembly 5. In this way, the air in the storage space can be continuously cooled and circulated to maintain the required temperature range.

[0093] The refrigeration equipment provided by the embodiments of the present application adopts a fan structure, which ensures that air can be smoothly sucked from the fan air inlet, uniformly discharged from multiple fan air outlets after the action of the fan. The multiple fan air outlets are symmetrically arranged on the two sides of the fan air inlet. This layout is not only beautiful, but also helps to achieve the uniformity and efficiency of air flow, thereby improving the heat exchange efficiency and air flow efficiency. At the same time, the drain port is located below the fan, which helps to timely discharge the condensate water generated during the refrigeration process, preventing the accumulation of water in the shell from causing moisture and corrosion problems.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the present application, and are not a limitation on the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
