[0052] The refrigerator according to the embodiments of this utility model can be as follows: Figure 1 The French three-door refrigerator shown can also be as follows: Figure 2 The double-door refrigerator shown is not limited to this example.

[0053] Please refer to the reference. Figure 4 , Figure 5 , Figure 9 and Figure 10 According to an embodiment of the present invention, the refrigerator includes a cabinet 1, a top air duct 11, and a compressor compartment module 150. The cabinet 1 is provided with a refrigeration chamber and an installation cavity spaced apart. The top air duct 11 is located on the top of the cabinet 1 and has a return air vent that connects to the refrigeration chamber. The compressor compartment module 150 includes a mounting base, a compressor, and a condenser. The compressor and condenser are mounted on the mounting base, and the mounting base is installed in the installation cavity.

[0054] like Figure 4 As shown, the refrigerator according to this embodiment of the present invention has a reasonable layout, which facilitates the expansion of the refrigeration compartment volume by placing the top air duct 11 on the top of the cabinet 1 and providing an installation cavity for installing the compressor compartment module 150. Meanwhile, the compressor compartment module 150 mounts the compressor and condenser via a mounting base. This allows the cabinet 1 and the compressor compartment module 150 to be manufactured separately, eliminating the need to install the compressor and condenser onto the cabinet 1 separately; they can simply be connected to the cabinet 1 via the mounting base, simplifying the manufacturing process and reducing assembly difficulty.

[0055] Please refer to the reference. Figure 9 and Figure 10 In this embodiment, the compressor compartment module 150 also includes, but is not limited to, a solenoid valve, a radiator, and a vibration damping device. The solenoid valve is connected to the compressor via a pipe and is used to control the flow of refrigerant. The radiator is used to assist in heat dissipation of components such as the compressor, thereby improving refrigeration efficiency. The vibration damping device can reduce the vibration generated by the compressor during operation. The solenoid valve, radiator, and vibration damping device are all mounted on the mounting base. In this way, multiple components such as the compressor, condenser, solenoid valve, radiator, and vibration damping device can be mounted on the mounting base outside the housing 1. By mounting the entire mounting base onto the housing 1, the assembly difficulty is reduced.

[0056] According to one embodiment of this utility model, the mounting base is detachably connected to the housing 1, for example, by screw connection, snap-fit ​​connection, etc., which is not limited herein, to improve the ease of assembly and disassembly, and facilitate subsequent assembly, disassembly, maintenance, or replacement of parts. In one embodiment, the mounting cavity opens from the side of the housing 1, and the mounting base can be pushed into the mounting cavity from the side opening of the mounting cavity. The mounting base can be in the form of a drawer structure, and can be installed in the mounting cavity by pulling it out, thereby improving the ease of assembly and disassembly.

[0057] According to one embodiment of the present invention, the mounting cavity is located at the bottom of the cabinet 1. According to another embodiment of the present invention, the refrigeration compartment includes a refrigerator compartment and a freezer compartment, with the refrigerator compartment located above the freezer compartment. A top air duct 11 is located at the top of the refrigerator compartment, and a return air vent connects to the refrigerator compartment. For example, the refrigerator compartment is located at the top of the refrigerator, the freezer compartment is located in the middle of the refrigerator, and the mounting cavity is located at the bottom of the refrigerator. Thus, the top air duct 11 is located at the top of the refrigerator compartment, and the top air duct 11 is spaced apart from the mounting cavity, ensuring that the internal components of both compartments do not interfere with each other, and allowing for a reasonable layout of the installation space. Optionally, the return air vent is located near the refrigerator compartment's opening frame, while the refrigerator compartment's air supply vent is located at the bottom inner side of the refrigerator compartment. Thus, the air supply vent and the return air vent are located diagonally opposite each other within the refrigerator compartment, ensuring uniform cold air coverage within the refrigerator compartment.

[0058] Please refer to the reference. Figure 6 , Figure 7 and Figure 8According to one embodiment of this utility model, an evaporator 51 and a water tank assembly 30 are provided inside the top air duct 11. The water tank assembly 30 has a water outlet 130, which is adapted to communicate with the refrigerator compartment. It should be noted that the top air duct 11 is located at the top of the inner side of the cabinet 1, so that the return air vent of the top air duct 11 is connected to the refrigerator compartment. It is understood that the evaporator 51 is installed inside the top air duct 11 so that the return air inside the top air duct 11 forms cold air. To reduce the supporting pressure on the bottom of the top air duct 11, the evaporator 51 can be fixed inside the top air duct 11 by hanging. For example, a fixing hook 52 is provided on the top of the evaporator 51. The number of fixing hooks 52 can be two or more. The evaporator 51 is hung on the top of the cabinet 1 by the fixing hooks 52 to prevent the top air duct 11 from being compressed and protruding into the refrigerator compartment.

[0059] In one embodiment, the water tank assembly 30 and the evaporator 51 are spaced apart in the top air duct 11 along the return air direction. For example, air entering the top air duct 11 from the return air inlet first passes through the water tank assembly 30, for instance, by contacting the outer wall of the water tank assembly 30, thus cooling the water inside to form cold water. The air then passes through the evaporator 51 to form a cold air circulation again. In this way, the cold water in the water tank assembly 30 can be discharged through the outlet 130 for user use. The outlet 130 can be located on the side wall of the refrigerator compartment for easy user access. Simultaneously, if water leaks from the outlet 130, it will flow down the side wall of the refrigerator compartment instead of dripping directly onto the food stored inside, thus avoiding affecting the food's storage effect.

[0060] Please refer to the reference. Figure 11 and Figure 12 According to one embodiment of the present invention, the housing 1 includes an outer shell assembly 250 and a support frame 300. The support frame 300 is supported inside the outer shell assembly 250, and the outer shell assembly 250 forms a cooling chamber and an installation cavity. The outer shell assembly 250 is installed on the support frame 300 by sheet metal splicing. It can be understood that the support frame 300 structure enhances the strength and stability of the housing 1.

[0061] According to one embodiment of the present invention, the support frame 300 is a metal frame to improve the support strength.

[0062] Please refer to the reference. Figure 3 , Figure 4 and Figure 12According to one embodiment of this utility model, the support frame 300 is provided with a top beam 20, and the refrigerator includes a door and a sliding door assembly. The door is rotatably connected to the refrigerator body 1 to open or close the cooling compartment. The sliding door assembly is connected to the top beam 20 and is used to drive the door to rotate. It is understood that by connecting the sliding door assembly to the top beam 20 to drive the door to rotate, the top beam 20 can better support the movement of the sliding door assembly when it is driven, thereby reducing the risk of deformation of the refrigerator body 1 after prolonged use.

[0063] Please refer to the reference. Figure 3 , Figure 7 and Figure 8 According to one embodiment of this utility model, the door push assembly includes a door push drive component 10, a top beam 20 is provided with a door hinge 200, and the box door is rotatably connected to the box body 1 through the door hinge 200. The door hinge 200 is also connected to the door push drive component 10, and the door push drive component 10 drives the door hinge 200 to rotate the box door. This is understandable. The door push drive component 10 can be installed inside the top air duct 11 and connected to the door hinge 200 on the top beam 20 to make reasonable use of the installation space, resulting in a compact top structure for the box body 1. The door push drive component 10 can be a motor or a cylinder, etc., and is not limited here, as long as it can drive the box door to rotate through the door hinge 200, thereby automatically opening the box door. For example, a trigger switch can be provided on the box door, allowing the user to trigger the door to open by pressing the trigger switch. For larger cabinet doors, users need to use a lot of force to open them. However, by using a push-door drive component 10 and a door hinge 200 to enable electric opening, users can easily open the cabinet door, improving the user experience.

[0064] According to one embodiment of this utility model, the refrigerator includes two doors. Door hinges 200 are provided at both ends of the top beam 20. Both door hinges 200 are connected to a door drive component 10, and each door hinge 200 corresponds to one door. It can be understood that this is a double-door refrigerator. Both doors can be opened simultaneously by one door drive component 10, saving one door drive component 10. Of course, when needed, the door drive component 10 can also be controlled to open only one door.

[0065] Please refer to the reference. Figure 3 and Figure 6According to one embodiment of this utility model, the support frame 300 is provided with a central beam 100, and a push-door switch 101 is provided on the central beam 100 for opening the cabinet door. In this embodiment, the central beam 100 can be used to separate the refrigerator compartment and the freezer compartment, so the push-door switch 101 can open the door of the freezer compartment accordingly. In other embodiments, the central beam 100 can also correspond to the bottom of the refrigerator compartment, and the push-door switch 101 can push the door open from the bottom of the door. Of course, the push-door switch 101 can also be used as a trigger switch for the user to press to control the door to open. Since the central beam 100 is located in the middle of the cabinet 1, the user can easily access it.

[0066] like Figure 6 As shown, according to one embodiment of the present invention, the refrigerator includes an ice maker assembly 120, which is disposed at the top of the freezer compartment. It is understood that an ice storage box is placed below the ice maker assembly 120, and the ice produced by the ice maker assembly 120 can fall into the ice storage box. The ice storage box is slidably connected to the inner wall of the freezer compartment, allowing it to slide out of the freezer compartment for easy access by the user.

[0067] like Figure 7 As shown, the refrigerator according to an embodiment of the present invention includes a cabinet 1, a top air duct 11, a water tank assembly 30, an evaporator 51, and a fan assembly 60. The cabinet 1 has a refrigeration compartment; the top air duct 11 is located at the top of the cabinet 1 and has a return air vent that connects to the refrigeration compartment; the water tank assembly 30 is located inside the top air duct 11 and has a water outlet 130 that is adapted to connect with the refrigeration compartment; the evaporator 51 is located inside the top air duct 11; and the fan assembly 60 is at least partially located inside the top air duct 11 and is located on the side of the evaporator 51 away from the return air vent.

[0068] According to this embodiment of the refrigerator, by placing the top air duct 11 at the top of the cabinet 1, the top air duct 11 forms a circulating air duct, allowing cold air to circulate within the refrigeration compartment. The water tank assembly 30 provides cold water to the refrigeration compartment through the water outlet 130 for user drinking. Simultaneously, the evaporator 51 and the fan assembly 60 are used to create cold air circulation. Thus, by installing the water tank assembly 30, evaporator 51, and fan assembly 60 corresponding to the top air duct 11, the structural layout is compact, space is utilized rationally, and the usable volume of the refrigeration compartment is maximized.

[0069] According to one embodiment of this utility model, the drinking water tank assembly 30 includes two water tanks, which are spaced apart. In this embodiment, the two water tanks are a left water tank 31 and a right water tank 32, both of which are positioned corresponding to the return air vent. For example, the return air vent is an elongated hole shape, and the left water tank 31 and right water tank 32 are spaced apart along the extension direction of the return air vent. In this way, the contact with cold air between the left water tank 31 and right water tank 32 is relatively uniform, and the water storage capacity is increased by making reasonable use of the installation space to install the two water tanks. If the water tanks are made into an elongated shape corresponding to the return air vent, it would be inconvenient to install other components.

[0070] According to one embodiment of the present invention, both water tanks are connected to the water outlet 130, that is, the two water tanks share a water outlet 130, so that users can use water at the same water outlet 130.

[0071] According to one embodiment of this utility model, the door drive component 10 is located between two water tanks. For example, the door drive component 10 is connected to the door hinge 200 through the gap between the two water tanks to avoid being blocked by the two water tanks. Simultaneously, when one door drive component 10 simultaneously drives two doors to open, the door drive component 10 is located in the middle position, with equal distances from both sides of the tank body 1, making the driving force of the door drive component 10 on both sides more even. Thus, by rationally arranging the installation positions of the three components, the structural compactness is improved, and installation space is saved.

[0072] like Figure 14 and Figure 15 As shown, according to one embodiment of the present invention, the fan assembly 60 is located on the side of the evaporator 51 away from the return air inlet. It can be understood that the fan assembly 60 draws air from the side of the evaporator 51 away from the return air inlet to the evaporator 51, and blows the air through the fan assembly 60 into the air supply duct, so that the cold air is recirculated into the cooling room.

[0073] Please refer to the reference. Figure 16 and Figure 17According to one embodiment of the present invention, the fan assembly 60 includes a fan housing 61 and a fan 62. At least a portion of the fan housing 61 is disposed within the top air duct 11. The fan housing 61 has an output air duct and an air inlet communicating with the output air duct, and the air inlet is connected to the top air duct 11. The fan 62 is disposed at the air inlet. It is understood that the fan housing 61 can extend vertically to allow the output air duct to deliver air downwards. According to one embodiment of the present invention, the refrigerator includes a back air duct 80, which is connected to the fan housing 61 and communicates with the output air duct. The back air duct 80 is used to deliver air to the cooling compartment. Thus, cold air can be delivered to the cooling compartment through the back air duct 80 of the refrigerator. Of course, in other embodiments, cold air can also be directly delivered to the cooling compartment through the output air duct. The fan 62 is disposed at the air inlet and is used to draw cold air from the top air duct 11 to the output air duct and blow out the cold air from the output air duct, thereby forming a cold air circulation.

[0074] like Figure 17 As shown, according to one embodiment of the present invention, branch passages 611 are provided on both sides inside the fan housing 61, and the branch passages 611 are connected to the output air duct. It can be understood that the branch passages 611 can deliver cold air to both sides of the refrigeration chamber to improve the uniformity of cold air in the refrigeration chamber.

[0075] Please refer to the reference. Figure 7 and Figure 13 According to an embodiment of the present invention, the refrigerator includes a cabinet 1, a top air duct 11, a first embedded part 27, and a water tank assembly 30. The cabinet 1 is provided with an inner liner, which forms a refrigeration compartment. The inner liner has a first mounting hole. The top air duct 11 is located at the top of the inner liner and has a return air vent that connects to the refrigeration compartment. The first embedded part 27 is installed in the first mounting hole. The water tank assembly 30 is located in the top air duct 11 and connected to the first embedded part 27. The water tank assembly 30 has a water outlet 130, which is adapted to communicate with the refrigeration compartment.

[0076] According to the refrigerator of this utility model embodiment, the inner liner has a first mounting hole. When the inner liner is formed using a vacuum forming mold, the problem of difficulty in forming the first mounting hole is avoided. A first embedded part 27 is installed in the first mounting hole and can be used to install and fix the water tank assembly 30. It is understood that the first embedded part 27 can be installed at the first mounting hole after the inner liner is formed. The first embedded part 27 is a plastic part, and the connection between the first embedded part 27 and the inner liner can be a detachable connection such as a snap-fit ​​connection or a screw connection to improve the ease of assembly and disassembly.

[0077] According to one embodiment of this utility model, a first mounting groove is recessed on the side of the first embedded part 27 facing the top air duct 11, and the water tank assembly 30 is at least partially accommodated in the first mounting groove. It is understood that if the first mounting groove were directly provided on the inner liner to accommodate the water tank assembly 30, the first mounting groove would be too deep, potentially causing the inner liner to be molded too deeply at the first mounting groove position, leading to molding difficulties. By at least partially accommodating the water tank assembly 30 in the first mounting groove, it is beneficial to protect the water tank assembly 30.

[0078] According to one embodiment of this utility model, the inner liner has two first mounting holes, each of which is fitted with a first embedded part 27. The drinking water tank assembly 30 includes two water tanks, each of which is mounted on a first embedded part 27. It is understood that each first embedded part 27 is used to install and fix one water tank, improving structural stability. Simultaneously, the first embedded part 27 can also be used to install and fix other components.

[0079] According to one embodiment of this utility model, the inner liner has a second mounting hole, and the refrigerator includes a second embedded part 29, which is installed in the second mounting hole. The fan assembly 60 is installed in the second embedded part 29. Similarly, if the position on the inner liner used to install and fix the fan assembly 60 is prone to molding difficulties, the fan assembly 60 is installed and fixed through the second embedded part 29.

[0080] According to one embodiment of this utility model, the second embedded part 29 has a second mounting groove recessed on the side facing the top air duct 11, and the fan assembly 60 is at least partially accommodated in the second mounting groove. It is understood that if the second mounting groove were directly provided on the inner liner to accommodate the fan assembly 60, the second mounting groove would be too deep, easily leading to difficulties in molding the inner liner at the second mounting groove position. By at least partially accommodating the fan assembly 60 in the second mounting groove, it is beneficial to protect the fan assembly 60.

[0081] According to one embodiment of the present invention, the inner liner includes a refrigerator inner liner 350 and a freezer inner liner. The refrigerator inner liner 350 forms a refrigerator compartment, and the freezer inner liner forms a freezer compartment. The refrigerator inner liner 350 has a first mounting hole, and a top air duct 11 is located at the top of the refrigerator inner liner 350. The freezer inner liner has a third mounting hole. The refrigerator includes an ice maker assembly 120 and a third embedded part. The third embedded part is installed in the third mounting hole, and the ice maker assembly 120 is installed in the third embedded part.

[0083] Please refer to the reference. Figure 18 , Figure 19 and Figure 20 According to an embodiment of the present utility model, the return air vent assembly 35 includes a fixed bracket 36, a display screen assembly 34, and a top front light assembly 40. The fixed bracket 36 forms a return air vent; the display screen assembly 34 is disposed on one side of the fixed bracket 36; and the top front light assembly 40 is disposed on the side of the fixed bracket 36 away from the display screen assembly 34.

[0084] According to an embodiment of this utility model, the return air vent assembly 35 is connected and fixed to the refrigerator body 1 via a fixed bracket 36. A return air vent is formed on the fixed bracket 36 to circulate cold air within the refrigerator's cooling compartment. Simultaneously, a display screen assembly 34 is provided on one side of the fixed bracket 36 for user observation and operation, and a top-mounted light assembly 40 is provided on the other side of the fixed bracket 36 for illumination. The top-mounted light assembly 40 is located on the side of the fixed bracket 36 away from the display screen assembly 34. Since the display screen assembly 34 faces the user, the top-mounted light assembly 40 will not shine directly onto the user, thus avoiding light interference with the user's viewing of the display screen assembly 34. In this way, the return air vent assembly 35 provides both lighting and screen display functions for the refrigerator.

[0085] In this embodiment, the display screen assembly 34 can be used to display the usage status of the refrigerator, such as the temperature of the refrigerator compartment and the freezer compartment. The return air vent assembly 35 is installed near the opening frame of the refrigerator compartment so that the user can easily observe the display screen assembly 34. At the same time, the overhead light assembly 40 shines towards the inside of the refrigerator compartment so that the user can observe the food storage status inside the refrigerator compartment.

[0086] For example, the return air vent on the fixed bracket 36 is located at the bottom and between the display screen assembly 34 and the top front light assembly 40. It is connected to the top air duct 11 through the return air vent assembly 35. The air in the cooling room enters the top air duct 11 through the return air vent. In this way, the return air vent of the return air vent assembly 35 can serve as the air inlet of the top air duct 11.

[0087] According to one embodiment of this utility model, the return air vent assembly 35 includes a light-transmitting plate, which is connected to a fixed bracket 36 and forms a lamp cavity. The top front light assembly 40 is installed inside the lamp cavity. It is understood that the top front light assembly 40 is installed inside the lamp cavity to prevent items inside the refrigerator from directly contacting the top front light assembly 40.

[0088] According to one embodiment of the present invention, a first hook is provided on one side of the fixing bracket 36, and a second hook is provided on the other side. The first hook and the second hook are used to connect with external devices. Optionally, the first hook and the second hook are used to engage and fix the bracket to the inner wall of the top air duct 11 to position and install the return air vent assembly 35, thereby improving the ease of installation.

[0089] According to one embodiment of this utility model, the return air vent assembly 35 includes a decorative panel 37, which covers the return air vent and has multiple spaced-apart return air mesh openings. It is understood that the overhead light assembly 40 and the display screen assembly 34 can be connected to the fixing bracket 36 by screws. When the decorative panel 37 covers the return air vent, it can cover the screws to prevent them from being exposed, thus improving aesthetics. The multiple spaced-apart return air mesh openings can be used for return air, and other items are difficult to pass through the return air mesh openings.

[0090] According to one embodiment of this utility model, at least one section of the return air vent is inclined toward the display screen assembly 34 in the vertical extension direction. For example, the return air vent forms a Z-shaped air duct, preventing users from seeing the internal structural components through the return air vent from the outside, thus ensuring the overall aesthetics of the device.

[0091] According to one embodiment of the present invention, the decorative panel 37 and the fixed bracket 36 are connected by a snap-fit ​​structure, which facilitates assembly and disassembly. According to another embodiment of the present invention, the decorative panel 37 and the fixed bracket 36 are provided with multiple sets of snap-fit ​​structures to improve connection stability.

[0092] According to one embodiment of this utility model, the return air vent assembly 35 includes an odor-removing module assembly 39, which is disposed on the fixed bracket 36 and corresponding to the return air vent. It is understood that the odor-removing module assembly 39 is located between the display screen assembly 34 and the top front light assembly 40. Air entering from the return air vent will pass through the odor-removing module assembly 39 into the top air duct 11. The odor-removing module assembly 39 can remove odors, allowing the purified air to circulate within the refrigerator, further improving the cleanliness and uniformity of the air inside the refrigerator, helping to maintain stable temperatures in different areas of the refrigerator, and enhancing the refrigerator's cooling effect and preservation performance.
