Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and more specifically, to a refrigerator. Background Technology

[0002] In existing technology, refrigerators (air-cooled) typically have a variable temperature compartment within the refrigerator compartment, usually formed by a drawer. Because the variable temperature compartment is a multi-functional area within the refrigerator compartment, and because it relies on the overall cooling system of the refrigerator, it often suffers from poor sealing and insulation. This leads to airflow between the variable temperature compartment and other compartments (refrigerator compartment), resulting in food odors mixing and a poor user experience. Summary of the Invention

[0003] This invention provides a refrigerator to solve the problem of food odor mixing caused by poor sealing and insulation of the variable temperature compartment in existing refrigerators.

[0004] To achieve the above objectives, the present invention provides a refrigerator, comprising: a cabinet body forming a compartment; a drawer assembly slidably connected to the cabinet body; a cover assembly fixedly connected to the cabinet body, the position of the cover assembly corresponding to the drawer assembly, and the cover assembly sealingly covering the drawer opening of the drawer assembly; the cover assembly is provided with an air duct structure, the first end of the air duct structure communicating with the refrigerator's refrigeration air inlet duct, and the second end of the air duct structure communicating with the drawer opening of the drawer assembly.

[0005] Furthermore, it also includes: a return air structure, where the internal cavity of the drawer assembly for placing food and the return air structure are connected by airflow; the refrigerated air inlet duct, the air duct structure, the internal cavity of the drawer assembly for placing food, and the return air structure form a refrigerated air circulation system.

[0006] Furthermore, it also includes: a sealing strip connected to the cabinet, the sealing strip and the outer surface of the drawer assembly forming a sealed space between the sealing strip, the outer surface of the drawer assembly, and the return air structure.

[0007] Furthermore, the sealing strip is located at the bottom of the drawer assembly and close to the operating end of the drawer assembly. The bottom of the drawer assembly is provided with ventilation holes, and the internal chamber of the drawer assembly is connected to the return air structure through the ventilation holes.

[0008] Furthermore, the drawer assembly includes: a drawer drawer having an internal cavity for placing food ingredients and a drawer opening; a drawer cover attached to the drawer drawer, with a layer of heat-insulating material filling the space between the drawer cover and the drawer drawer.

[0009] Furthermore, the drawer assembly includes: a drawer seal strip, which is sealed between the drawer front and the drawer drawer, and the drawer seal strip is wrapped around the outer periphery of the insulation material layer.

[0010] Furthermore, the drawer assembly includes: a counterweight installed at the bottom of the drawer drawer; a support rib structure with a slide rail, the drawer drawer being slidably connected to the body via the slide rail, the slide rail being inclined relative to the bottom wall of the drawer drawer, the drawer drawer being able to slide back into place under its own weight and the weight of the counterweight.

[0011] Furthermore, the slide rail is equipped with a locking bend; when the drawer slides to the locking bend, the locking bend locks the drawer drawer in place.

[0012] Furthermore, the cover assembly includes: an upper cover and a lower cover disposed opposite to each other; a duct foam is disposed between the upper cover and the lower cover, and a duct structure is formed on the duct foam; the lower cover is disposed corresponding to the drawer opening, and the second end of the duct structure is disposed on the lower cover and forms an air vent.

[0013] Furthermore, a lighting fixture is installed on the lower cover plate.

[0014] Furthermore, the top cover is equipped with a display panel and a glass panel, with the glass panel covering the display panel. The display panel is used to display status and functions, while the glass panel can be operated by touch buttons.

[0015] Furthermore, the compartment includes a refrigerated compartment, and a variable temperature compartment is formed between the drawer assembly and the cover assembly.

[0016] The drawer assembly and lid assembly form an independent variable-temperature compartment, which is relatively isolated from other compartments, resulting in better insulation. The air duct structure on the lid assembly guides the cold air from the refrigerator's intake duct into the drawer assembly. This means the variable-temperature compartment uses a separate airflow duct, preventing cross-contamination of airflow between the compartment and other compartments. This also prevents food in the variable-temperature compartment from absorbing odors from other areas, solving the sealing problem, improving the user experience, and increasing user satisfaction.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0024] See Figures 1 to 6 As shown, according to an embodiment of the present invention, a refrigerator is provided, the refrigerator including a cabinet 10, a drawer assembly 20 and a cover assembly 30, the cabinet 10 forming a cabinet compartment; the drawer assembly 20 is slidably connected to the cabinet 10; the cover assembly 30 is fixedly connected to the cabinet 10, the position of the cover assembly 30 corresponds to the drawer assembly 20, and the cover assembly 30 can seal and cover the drawer opening of the drawer assembly 20; the cover assembly 30 is provided with an air duct structure 41, the first end of the air duct structure 41 is connected to the refrigerator's refrigeration air inlet duct 42, and the second end of the air duct structure 41 is connected to the drawer opening of the drawer assembly 20.

[0025] An independent variable-temperature compartment is formed between the drawer assembly 20 and the cover assembly 30. This independent variable-temperature compartment is relatively isolated from other compartments, resulting in better insulation performance. The air duct structure 41 on the cover assembly 30 can introduce cold air from the refrigerator's cooling air duct 42 into the drawer assembly 20. In other words, the cooling inside the variable-temperature compartment uses a separate airflow duct, so the independent variable-temperature compartment will not experience cross-contamination with other compartments. This prevents food in the variable-temperature compartment from absorbing odors from food in other functional areas, solving the sealing problem of the variable-temperature compartment, improving the user experience, and increasing user satisfaction.

[0026] Preferably, the compartment includes a refrigerator compartment, and the drawer assembly 20 and the cover assembly 30 form a variable temperature compartment. In this embodiment, both the drawer assembly 20 and the cover assembly 30 are located within the refrigerator compartment.

[0027] See Figure 1The refrigerator also includes a return air structure 50, and the internal cavity 22 of the drawer assembly 20 for placing food is connected to the return air structure 50 by airflow. The refrigerator air inlet duct 42, the air duct structure 41, the internal cavity 22 of the drawer assembly 20 for placing food, and the return air structure 50 form a refrigerator air circulation system. The return air structure 50 is the return air vent on the cabinet 10. In this embodiment, the drawer assembly 20 is located in the refrigerator compartment, and the return air structure 50 is also the return air vent on the lining of the refrigerator compartment. The refrigerator air inlet duct 42 is provided with a damper structure. When the damper structure is opened, the cold air from the freezer compartment is delivered to the refrigerator compartment. Due to the connection between the cover assembly 30 and the refrigerator air inlet duct 42, the cold air enters the air duct structure of the cover assembly 30 and then enters the drawer assembly 20. The cold air sinks to the lower position of the drawer assembly 29 and returns to the refrigerator air duct through the return air vent. The overall airflow forms a refrigerator air circulation system.

[0028] The refrigerator also includes a sealing strip 60, which is connected to the cabinet 10. The sealing strip 60 and the outer surface of the drawer assembly 20 are sealed together, forming a sealed space between the sealing strip 60, the outer surface of the drawer assembly 20, and the return air structure 50. The sealing strip 60 is installed and connected to the cabinet 10 (refrigerator liner) by screws. The sealing strip mates with the front face of the drawer assembly. After the refrigeration system is turned on, the sealing strip can prevent cold air from leaking out, thus achieving the effect of drawer insulation.

[0029] See Figure 1 The sealing strip 60 is located at the bottom of the drawer assembly 20 and near the operating end of the drawer assembly 20. The bottom of the drawer assembly 20 has ventilation holes, and the internal chamber 22 of the drawer assembly 20 is connected to the return air structure 50 through the ventilation holes. The sealing strip 60 prevents cold air from leaking out from the front end (user operating end) of the drawer assembly 20, ensuring the drawer's insulation effect. The sealing strip 60 also allows cold air entering the drawer assembly 20 to return directly to the return air structure 50 through the ventilation holes, increasing airflow smoothness.

[0030] See Figure 2 and Figure 3 The drawer assembly 20 includes a drawer drawer 21 and a drawer front panel 23. The drawer drawer 21 forms an internal cavity 22 for placing food items and a drawer opening. The drawer front panel 23 is attached to the drawer drawer 21, and a heat-insulating material layer 24 is filled between the drawer front panel 23 and the drawer drawer 21. The exterior of the drawer front panel 23 uses a glass panel, which integrates the variable temperature compartment with other drawers. The function of the heat-insulating material layer 24 is to ensure that when the refrigeration system is turned on, cold air forms a stable state inside the drawer, and the heat-insulating material prevents the drawer assembly from being affected by external airflow.

[0031] The drawer assembly 20 includes a drawer seal 25, which is sealed between the drawer front cover 23 and the drawer drawer 21. The drawer seal 25 is wrapped around the outer periphery of the insulation material layer 24. The drawer seal 25 engages with the drawer front cover via a snap-fit ​​mechanism, and can also engage with a sealing strip to form a sealed space.

[0032] The drawer assembly 20 includes a counterweight 26 and a support rib structure 27. The counterweight 26 is installed at the bottom of the drawer drawer 21. The support rib structure 27 forms a slide rail 28, through which the drawer drawer 21 is slidably connected to the cabinet 10. The slide rail 28 is inclined relative to the bottom wall of the drawer drawer 21, allowing the drawer drawer 21 to slide back into place under its own weight and the weight of the counterweight 26. The counterweight 12 (which can be glass, but is not limited to) is located at the bottom of the drawer and is secured to the drawer drawer 21 by the rib structure on the drawer drawer 21. Due to the counterweight at the bottom of the drawer, the drawer will automatically return to its original position under the action of gravity. The newly designed drawer achieves a mechanical self-returning function through its own structure and its own weight.

[0033] Preferably, the slide rail 28 is provided with a locking bend 29. When the drawer body 10 slides to the locking bend 29, the locking bend 29 locks the drawer drawer 21 in place. The locking bend 29 is a bend in the slide rail 20 at a certain angle. When the drawer drawer 21 is pulled out to a certain position, the locking bend 29 locks in place without restricting the drawer drawer from returning to its original position.

[0034] like Figures 4 to 6 As shown, the cover assembly 30 includes an upper cover 31 and a lower cover 32 disposed opposite to each other. A duct foam 33 is disposed between the upper cover 31 and the lower cover 32, and a duct structure 41 is formed on the duct foam 33. The lower cover 32 is correspondingly positioned to the drawer opening, and the second end of the duct structure 41 is disposed on the lower cover 32, forming an air vent. The duct foam, disposed between the upper and lower covers, is designed with a uniform and suitable duct structure according to the compartment volume and cooling capacity requirements, and delivers cold air to the internal chamber 22 (variable temperature compartment) through the air vent on the lower cover 32. The duct foam 33 has a multi-functional effect; it not only forms the duct structure 41 and does not absorb cold air from the cold air, ensuring cooling efficiency, but also provides insulation to the cover assembly 30, improving the insulation effect of the variable temperature compartment.

[0035] A lighting lamp 34 is installed on the lower cover plate 32 and is connected via a snap-fit ​​mechanism. The upper cover plate 31 has a display panel 35 and a glass panel 36, with the glass panel 36 covering the display panel 35. The display panel 35 displays status and functions, while the glass panel 36 is operable via touch buttons. Both the refrigerator compartment and the variable temperature compartment are equipped with temperature sensors. The variable temperature compartment's function is set via touch buttons on the glass panel 36. The temperature sensors transmit information to the main control board, which controls the opening and closing of the air dampers to maintain the variable temperature compartment within the set functional temperature range.
