Description

TECHNICAL FIELD

[0001] The utility model belongs to refrigerator technical equipment field especially relates to a refrigerator. BACKGROUND

[0002] At present, along with the development of flat-embedded refrigerator, the volume of refrigerator is getting smaller and the capacity is getting larger, which means that the volume of various structures in the heat preservation bubble layer of refrigerator is getting smaller.

[0003] The air supply pipeline is the channel for conveying cold energy from the freezer compartment to the refrigerator compartment, and it is the largest structure in the bubble layer of the refrigerator. In order to reduce the volume of the air supply pipeline as much as possible, a plastic pipeline is used to replace the traditional foam pipeline.

[0004] However, the heat conduction performance of the plastic pipeline is higher than that of the foam pipeline, so a damper heating wire needs to be added at the air supply port connected to the freezer tank of the refrigerator. Through the heating wire, icing phenomenon can be prevented at the air supply port position of the plastic pipeline. However, the addition of the damper heating wire increases the manufacturing difficulty of the air supply pipeline, and the heating wire also increases the energy consumption during the operation of the refrigerator. SUMMARY

[0028] Referring to Figures 1 to 3 The refrigerator 100 provided by the embodiment of the present application comprises a cabinet structure 140, a middle beam 130 connected to the cabinet structure 140, and an air supply assembly 200 connected to the middle beam 130. The cabinet structure 140 has a freezing compartment 110 and a refrigerating compartment 120 arranged apart from the freezing compartment 110. In actual use, the height direction of the cabinet structure 140 is arranged along the vertical direction, and the freezing compartment 110 and the refrigerating compartment 120 are arranged apart along the horizontal direction.

[0029] Referring to Figures 2 to 4 The middle beam 130 is located between the freezing compartment 110 and the refrigerating compartment 120. It can be understood that the freezing compartment 110 and the refrigerating compartment 120 are separated by a structural plate, and the middle beam 130 is located at the position of the structural plate. The length direction of the middle beam 130 is arranged along the vertical direction. The air supply assembly 200 comprises a first air supply pipe 201 made of a first material and a second air supply pipe 202 made of a second material. The first air supply pipe 201 and / or the second air supply pipe 202 are connected to the middle beam 130, so as to fix the air supply assembly 200.

[0030] The one end of the first air supply pipe 201 is communicated with the one end of the second air supply pipe 202, the other end of the first air supply pipe 201 is communicated with the freezing chamber 110, the other end of the second air supply pipe 202 is communicated with the refrigerating chamber 120, the freezing chamber 110 has cold air for freezing food, the cold air can flow from the freezing chamber 110 into the first air supply pipe 201, and then flow from the first air supply pipe 201 into the second air supply pipe 202, and then flow from the second air supply pipe 202 into the refrigerating chamber 120, and the heat conduction performance of the first material is lower than that of the second material, and it can be understood that the lower the heat conduction performance, the less likely to freeze and frost in a low-temperature environment, and the higher the heat conduction performance, the more likely to freeze and frost in a low-temperature environment.

[0031] Please refer to Figures 2 to 4 The refrigerator 100 provided by the embodiment of the present application sets the middle beam 130 between the freezing chamber 110 and the refrigerating chamber 120, and arranges the air supply assembly 200 made of materials with different heat conduction performance on the middle beam 130, so that the first air supply pipe 201 with low heat conduction performance is communicated with the freezing chamber 110 and arranged at a position near the freezing chamber 110 without affecting the foaming thickness, the first air supply pipe 201 receives the cold air from the freezing chamber 110, and the second air supply pipe 202 with high heat conduction performance is arranged at a position of the middle beam 130 to the refrigerating chamber 120 which affects the foaming thickness, and the second air supply pipe 202 transports the cold air to the refrigerating chamber 120, since the heat conduction performance of the first air supply pipe 201 is relatively low, the position where the first air supply pipe 201 is communicated with the freezing chamber 110 will not freeze, and it is not necessary to set the heating wire at the air inlet position of the first air supply pipe 201, thereby reducing the energy consumption of the refrigerator 100 in the running process, and reducing the manufacturing difficulty of the air supply assembly 200.

[0032] Please refer to Figures 2 to 4 In some embodiments, the first air supply pipe 201 is made of foam material, and the second air supply pipe 202 is made of plastic material.

[0033] Optionally, the heat conduction performance of the foam material is lower than that of the plastic material, by setting the first air supply pipe 201 made of foam material at the freezing chamber 110, the freezing phenomenon of the first air supply pipe 201 made of foam material can be avoided, and by setting the second air supply pipe 202 made of plastic material, the volume of the second air supply pipe 202 can be effectively reduced, thereby facilitating the maximization of the volume of the refrigerator 100. The use of plastic material ensures the structural strength and durability of the second air supply pipe 202, and enhances the long-term use performance of the equipment.

[0034] Please refer to Figures 2 to 4In some embodiments, the first air supply pipe 201 and the second air supply pipe 202 are connected by butt joint, the butt joint end of the first air supply pipe 201 has a first butt joint surface 2012, the butt joint end of the second air supply pipe 202 has a second butt joint surface 2024, and the first butt joint surface 2012 butts the second butt joint surface 2024.

[0035] Optionally, the first air supply pipe 201 and the second air supply pipe 202 are connected by butt joint, which can simplify the installation and maintenance of the first air supply pipe 201 and the second air supply pipe 202, and improve the flexibility and compatibility of the installation.

[0036] Please refer to Figures 2 to 4 In some embodiments, the edge of the first butt joint surface 2012 is provided with a plurality of first serrations 2014 arranged at intervals, the edge of the second butt joint surface 2024 is provided with a plurality of second serrations 2023 arranged at intervals, and each of the first serrations 2014 engages with each of the second serrations 2023.

[0037] Optionally, the engagement of the first serrations 2014 and the second serrations 2023 can make the first air supply pipe 201 and the second air supply pipe 202 butt tightly, prevent the leakage of cold air, and effectively improve the efficiency of cold air flow and the energy efficiency of the refrigerator 100. Moreover, the engagement of the first serrations 2014 and the second serrations 2023 can also improve the quick alignment and assembly of the first air supply pipe 201 and the second air supply pipe 202.

[0038] Please refer to Figures 4 to 5 Optionally, the first butt joint surface 2012 is quadrangular, the second butt joint surface 2024 is also quadrangular, and the area of the second butt joint surface 2024 is slightly larger than that of the first butt joint surface 2012, so that the cold air in the first air supply pipe 201 can flow smoothly into the second air supply pipe 202. A plurality of first grooves 2013 arranged at intervals are formed on the edge of the first butt joint surface 2012, two adjacent first grooves 2013 jointly separate the first serrations 2014, and a plurality of second grooves 2022 arranged at intervals are also formed on the edge of the second butt joint surface 2024, two adjacent second grooves 2022 jointly separate the second serrations 2023.

[0039] Please refer to Figures 4 to 5 Optionally, the first grooves 2013 extend to the edges of the first butt joint surface 2012 arranged oppositely. The second grooves 2022 can extend to the edges of the second butt joint surface 2024 arranged oppositely, or a plurality of second grooves 2022 are formed on one edge of the second butt joint surface 2024, and a lap joint structure is arranged on the other edge of the second butt joint surface 2024 opposite to the second grooves 2022. The lap joint structure can be a sealing element to seal the first grooves 2013 at the corresponding position.

[0040] Please refer to Figures 2 to 4In some embodiments, the middle beam 130 has a mounting surface for the first air supply pipe 201 and / or the second air supply pipe 202 to be arranged on, and the size of the first air supply pipe 201 is greater than that of the second air supply pipe 202 in the direction perpendicular to the mounting surface.

[0041] It can be understood that the first air supply pipe 201 is connected to the mounting surface, and the second air supply pipe 202 is connected to the first air supply pipe 201; or the second air supply pipe 202 is connected to the mounting surface, and the first air supply pipe 201 is connected to the second air supply pipe 202; in the present embodiment, the first air supply pipe 201 and the second air supply pipe 202 are both connected to the mounting surface, and in other embodiments, the selection can be made according to the actual situation, which is not limited herein.

[0042] Optionally, the first air supply pipe 201 is made of foamed material, which has poor heat conduction performance but large volume, and is not conducive to the flow of foamed material, so as to be arranged at a position in the freezing chamber 110 that does not affect foaming and to minimize the impact on the volume of the freezing chamber 110.

[0043] The second air supply pipe 202 made of plastic material can be arranged at a position of the middle beam 130 that affects the foaming thickness of the freezing chamber 120, and since the second air supply pipe 202 made of plastic material has poor heat conduction performance but small volume, it can not only reduce the impact on the foaming process, but also minimize the impact on the volume of the freezing chamber 120, so as to maximize the volume of the refrigerator 100 without the need to set a heating wire, and to reduce the overall manufacturing difficulty of the air supply assembly 200 and the energy consumption of the refrigerator 100 in the running process.

[0044] Please refer to Figures 2 to 4 In some embodiments, the surface of the first air supply pipe 201 towards the mounting surface further protrudes a support column 212.

[0045] Optionally, the free end of the support column 212 abuts against the back plate of the freezing chamber 110, so as to keep the freezing chamber 110 at a set distance from the first air supply pipe 201, and during the foaming process, the refrigerator 100 is arranged upwards, and the freezing chamber 110 is above the air supply assembly 200, so that the support column 212 can not only prevent the falling phenomenon, but also ensure the position of the air supply assembly 200, position the first air supply pipe 201, and effectively ensure the relative distance between the air supply assembly 200 and the freezing chamber 110 during foaming.

[0046] Please refer to Figures 2 to 4In some embodiments, the flow path of the first air supply pipe 201 is smaller than the flow path of the second air supply pipe 202 along the flow path of the cold air. That is, the flow path of the cold air in the first air supply pipe 201 is relatively small, while the flow path of the cold air in the second air supply pipe 202 is relatively large, so that the length of the first air supply pipe 201 along the flow path of the cold air is smaller than the length of the second air supply pipe 202. Under the premise of ensuring the air supply performance and preventing icing, the overall volume of the air supply assembly 200 can be minimized, thereby increasing the overall volume of the refrigerator 100 and reducing the manufacturing difficulty of the air supply pipeline and the energy consumption during the operation of the refrigerator 100.

[0047] Referring to Figures 2 to 4 In some embodiments, the first air supply pipe 201 has an air inlet 2011 communicating with the freezing chamber, the second air supply pipe 202 has an air outlet 2021 communicating with the refrigerating chamber, and the refrigerator 100 further comprises a damper arranged at the air inlet 2011.

[0048] Optionally, by arranging the damper at the air inlet 2011, the inflow and outflow of the cold air flow are effectively controlled, and the accuracy of the temperature control of the refrigerator 100 is improved. The design of the damper not only adjusts the air flow, but also prevents the leakage of cold air, ensures the temperature stability of the freezing chamber 110 and the refrigerating chamber 120, and improves the energy saving effect and refrigeration efficiency of the refrigerator 100.

[0049] Referring to Figures 2 to 4 In some embodiments, the air inlet 2011 is provided with a positioning groove 2015 arranged along the circumference of the air inlet 2011 and communicating with the air inlet 2011, and the damper is arranged in the positioning groove 2015 and used to open or close the air inlet 2011.

[0050] Optionally, the positioning groove 2015 is adapted to the shape of the outer contour of the damper, and the damper and the positioning groove 2015 are connected by interference fit. The size of the first air supply pipe 201 extends at least to the middle beam 130.

[0051] Optionally, the combination of the positioning groove 2015 provided in the air inlet 2011 and the damper enables the damper to more accurately open or close the air inlet 2011, thereby effectively controlling the inflow amount of the cold air flow. The positioning groove 2015 can position and fix the damper, and improve the accurate position and motion trajectory of the rotation of the damper.

[0052] Referring to Figures 4 to 5Optionally, the first air supply pipe 201 comprises a first part 211 and a second part 221 adapted to the first part 211, the positioning groove 2015 and the air inlet 2011 are both partially located in the first part 211 and partially located in the second part 221, and the first part 211 and the second part 221 can facilitate the manufacturing of the first air supply pipe 201.

[0053] Referring to Figures 4 to 5 In some embodiments, the second air supply pipe 202 comprises a first half pipe 212 and a second half pipe 222, the first half pipe 212 and the second half pipe 222 are snap connected, and the first half pipe 212 and the second half pipe 222 are both connected to the first air supply pipe 201.

[0054] Optionally, along the flow path of the cold air, a plurality of buckling heads 242 are arranged on both sides of the first half pipe 212, a plurality of buckling grooves 252 are arranged on both sides of the second half pipe 222, each buckling head 242 on one side of the first half pipe 212 is snap connected to each buckling groove 252 on one side of the second half pipe 222, and each buckling head 242 on the other side of the first half pipe 212 is snap connected to each buckling groove 252 on the other side of the second half pipe 222, thereby improving the disassembly and installation of the second air supply pipe 202.

[0055] Referring to Figures 4 to 5 In some embodiments, the refrigerator 100 further comprises a plurality of fixed buckles 232 arranged on the first half pipe 212.

[0056] Optionally, the second air supply pipe 202 can be detachably fixed to other structural members of the refrigerator 100 through the fixed buckles 232, thereby improving the stability of the second air supply pipe 202, and the plurality of fixed buckles 232 are arranged at intervals, thereby improving the stability and durability of the connection of the second air supply pipe 202.

[0057] It can be understood that the refrigerator 100 further comprises a fan and an evaporator, the cold air is transmitted from the fins of the evaporator to the air door by the fan, transmitted from the first air supply pipe 201 to the second air supply pipe 202 through the air door, and transmitted into the refrigeration compartment 120 through the second air supply pipe 202.

[0058] To prevent icing at the air door, the defrosting time is associated with the temperature of the refrigeration compartment 120 and the freezing compartment 110 and the number of door openings. That is, the defrosting time is adjusted according to the temperature of the refrigeration compartment 120 and the freezing compartment 110 and the number of door openings. When the temperature of the refrigeration compartment or the freezing compartment is higher, the frequency of defrosting is increased. The number of door openings also affects the defrosting time, because when the door is opened, the cold air will leak out, causing the temperature to change and increasing the likelihood of icing. Therefore, the system automatically adjusts the defrosting time according to these factors, thereby maintaining the efficient operation of the equipment and avoiding unnecessary icing.

[0059] The above merely provides the optional embodiments of the present application, but do not limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the principles and technical scope of the present application should be included in the protection of the present application.
