[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0032] In addition, the reference numbers and / or reference letters can be repeated in different examples in the present application, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the application of other processes and / or the use of other materials.

[0033] The present application will be described below in conjunction with the drawings and with reference to specific embodiments:

[0034] ​Some refrigerators have a temperature relatively lower ice temperature room in the refrigeration room, and a heat insulation structure is arranged between the ice temperature room and the refrigeration room, or a heating wire is additionally arranged, so as to maintain the temperature of the ice temperature room and avoid the low temperature of the ice temperature room from causing the stored items in the refrigeration room to freeze. However, the heat insulation structure occupies a certain space in the refrigerator, and the heating wire also occupies a certain space and causes additional heating energy consumption, thereby causing a loss of volume and energy consumption in the refrigerator as a whole.

[0035] Therefore, the embodiments of the present application provide a drawer cover plate, a drawer assembly and a refrigerator, which aim to solve the technical problems of large space occupation and high energy consumption of the heat insulation structure of the ice temperature room to a certain extent, so as to achieve the technical effect of balancing the heat insulation performance and small space occupation.

[0036] Figure 1 An exploded view of the drawer cover plate in the embodiments of the present application is shown; Figure 2 A sectional view of the drawer cover plate in Figure 1 is shown; Figure 3 A structural schematic view of the drawer assembly in the embodiments of the present application is shown.

[0037] Referring to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the heat insulation and heat preservation capability of the drawer cover plate 1 can be improved, the ice temperature room 31 is surrounded by the drawer cover plate 1 and the drawer 2, and the heat insulation and heat preservation structure between the refrigeration room 32 and the ice temperature room 31 of the refrigerator is simplified, so as to reduce the volume of the heat insulation and heat preservation structure to a certain extent and reduce the occupation of the internal space of the refrigerator.

[0038] The drawer cover plate 1 can include a cover plate body 11 and a partition plate 12, the partition plate 12 is connected to the cover plate body 11, and a heat insulation cavity 13 is surrounded between the partition plate 12 and the cover plate body 11.

[0039] The heat insulation cavity 13 is a hollow cavity, and the thermal conductivity of the heat insulation cavity 13 is lower than that of the partition plate 12 and the cover plate body 11, and the heat insulation cavity 13 is located between the partition plate 12 and the cover plate body 11, so as to form a heat resistance structure on the cover plate body 11 and improve the heat insulation and heat preservation performance of the cover plate body 11 as a whole.

[0040] In the case of being assembled into the refrigerator, the cover plate body 11 configured with the heat insulation cavity 13 can form a temperature gradient of ice temperature cold air-partition plate 12-heat insulation cavity 13-cover plate body 11-refrigeration hot air, so as to weaken the heat transfer between the drawer 2 and the refrigeration room 32, thereby maintaining the temperature of the internal ice temperature room 31 of the drawer 2 and reducing the risk of freezing of the items in the refrigeration room 32 close to the cover plate body 11.

[0041] The heat transfer efficiency between the ice temperature room 31 and the external environment can be greatly reduced through the heat insulation cavity 13, so that the heat insulation material structure does not need to be additionally arranged, thereby simplifying the heat insulation structure between the ice temperature room 31 and the refrigeration room 32 as a whole, reducing the volume of the heat insulation structure, and reducing the occupied internal volume of the refrigerator.

[0042] Since the drawer cover plate 1 can reduce the icing risk of the stored items in the refrigeration room 32, the electric heating wire for limiting the heat transfer between the ice temperature room 31 and the refrigeration room 32 does not need to be arranged, thereby also simplifying the heat insulation structure to a certain extent, reducing the volume, and reducing the occupied internal volume of the refrigerator. Since the electric heating wire does not need to be arranged, energy loss is avoided.

[0043] The drawer cover plate, the drawer assembly, and the refrigerator provided by the embodiment of the present application comprise a cover plate body and a partition plate, the partition plate is connected to the cover plate body, and a heat insulation cavity is arranged between the partition plate and the cover plate body. The heat transfer efficiency of the drawer cover plate is reduced by utilizing the low heat conduction coefficient of the cavity, the heat insulation performance of the drawer cover plate is improved, the heat insulation requirement between the ice temperature room and the refrigeration room is met, and the additional heat insulation layer or the heating wire structure does not need to be arranged, thereby reducing the overall volume of the ice temperature room to a certain extent. Therefore, the gap formed between the partition plate and the cover plate body can meet the heat insulation requirement of the ice temperature room and relatively lower occupied space, and the space utilization rate in the refrigerator is improved.

[0044] In some embodiments, the heat insulation cavity 13 can be arranged as a cavity, the inside of which is naturally filled with air, the heat conduction coefficient of which is about 0.024-0.028 W / (m·K), and the cavity has good heat insulation effect.

[0045] In some embodiments, carbon dioxide, argon, or other gas with a lower heat conduction coefficient than air can be filled in the heat insulation cavity 13, so as to further improve the heat insulation capacity of the drawer cover plate 1.

[0046] In some embodiments, the heat insulation cavity 13 can be evacuated to a vacuum state, so as to further reduce the heat transfer efficiency of the heat insulation cavity 13, thereby reducing the heat insulation performance of the drawer cover plate 11 as a whole.

[0047] In some embodiments, a sunken container groove 12a can be formed on the surface of the partition plate 12, and the container groove 12a and the surface of the cover plate body 11 are buckled to form the heat insulation cavity 13.

[0048] In some embodiments, an adhesive can be arranged between the contact surface of the partition plate 12 and the cover plate body 11, so as to fix the partition plate 12 on the cover plate body 11, and the stability of the fixed partition plate 12 and the simplicity of the structure of the installation are considered.

[0049] In some embodiments, the surface of the partition plate 12 and the surface of the cover plate body 11 can be attached to seal the heat insulation cavity 13, so as to ensure the stability of the heat insulation effect.

[0050] The adhesive can also be filled in the attachment gap between the plate surface of the partition plate 12 and the plate surface of the cover plate body 11, so as to stably fix the partition plate 12 on the cover plate body 11 and seal the gap between the partition plate 12 and the cover plate body 11, thereby improving the sealing performance of the heat insulation cavity 13.

[0051] Meanwhile, due to the attachment of the plate surface of the partition plate 12 and the plate surface of the cover plate body 11, the overall thickness of the drawer cover plate 1 is smaller than the thickness of the specially arranged heat insulation structure, and the space volume occupied is smaller.

[0052] In some embodiments, in order to balance the fixing reliability of the partition plate 12 and the sealing performance of the heat insulation cavity 13, the width of the adhesive sealing area of the partition plate 12 and the cover plate body 11 can be set to 20mm-30mm. For example, the width of the adhesive sealing area can be 20mm, 22mm, 24mm, 26mm, 28mm, 30mm or other values between 20mm-30mm, which is not specifically limited here.

[0053] In some embodiments, the specifications of the heat insulation cavity 13 can be reasonably set to meet the heat insulation performance requirements. The distance from the groove bottom of the container groove 12a to the cover plate body 11 can be set to 2mm-4mm, that is, the depth specification of the heat insulation cavity 13 in the thickness direction of the drawer cover plate 1 is 2mm-4mm. For example, the distance from the groove bottom of the container groove 12a to the cover plate body 11 can be 2mm, 2.4mm, 2.8mm, 3.2mm, 3.6mm, 4mm or other values between 2mm-4mm, which is not specifically limited here.

[0054] The greater the distance from the groove bottom of the container groove 12a to the cover plate body 11, the better the heat insulation performance, but it also makes the volume of the drawer cover plate 1 larger and the cost higher. Therefore, according to the temperature difference between the ice temperature room 32 and the refrigeration room 31 to be isolated, the distance from the groove bottom of the container groove 12a to the cover plate body 11 can be reasonably set to balance the heat insulation performance and the volume of the drawer cover plate 1.

[0055] In some embodiments, in order to improve the temperature stability of the ice temperature room 31 surrounded by the drawer cover plate 1 and the drawer 2, the gap between the drawer 2 and the drawer cover plate 1 can be adapted. The drawer cover plate 1 can also include a sealing strip 14, which can be arranged at the edge of the partition plate 12, so as to adapt to the gap between the partition plate 12 and the drawer 2, improve the sealing degree of the drawer 2, and improve the heat preservation and insulation capacity of the drawer 2 as a whole.

[0056] The sealing strip 14 can be elastically and flexibly sealed with the upper edge of the panel around the drawer 2, which can avoid the mixing of cold air and hot air to cause condensation at the edge of the drawer 2.

[0057] In some embodiments, the sealing strip 14 can be provided as a sealing ring 14a, and the shape and size of the sealing ring 14a are adapted to the shape and size of the partition plate 12 to be stably mounted on the edge of the partition plate 12.

[0058] In some embodiments, the sealing strip 14 can be made of elastic sealing silica gel or soft PVC material to adapt to the gap shape and size of the drawer 2 and the drawer cover plate 1. Thus, the sealing capability in a low-temperature environment is enhanced, the heat exchange between the drawer 2 and the refrigeration chamber 32 is reduced, and the overcooling defect of the refrigeration chamber 32 is avoided. The circulation utilization rate of the refrigeration air inside the ice temperature chamber 31 is also improved.

[0059] In some embodiments, in order to facilitate the installation of the sealing strip 14, a rubber strip card seat 14b can be provided on the partition plate 12, and the sealing strip 14 is clamped in the rubber strip card seat 14b.

[0060] In some embodiments, the cover plate body 11 can be made of a glass panel, which takes into account the structural strength and load capacity to bear refrigeration items.

[0061] In some embodiments, the partition plate 12 is made of a plastic material such as hard PVC or PP, which takes into account the advantages of light weight and high structural strength.

[0062] In some embodiments, a drawer assembly is also provided, which includes the drawer 2 and the above-mentioned drawer cover plate 1, and the drawer cover plate 1 is matched and covers the drawer 2 to enclose the above-mentioned ice temperature chamber 31.

[0063] By matching the size, the partition plate 12 is adapted to be arranged on the top of the drawer 2 to limit the heat transfer between the top of the drawer 2 and the external environment, and to maintain the temperature stability inside the drawer 2.

[0064] In some embodiments, the drawer 2 can include a body 21 and a return air cavity 22, and the return air cavity 22 is arranged on the body 21. The return air cavity 22 is provided with a return air window 22a and a return air collection port 22b, and the area of the return air window 22a is greater than the area of the return air collection port 22b. Thus, the airflow in the body 21 enters the return air cavity 22 through the return air window 22a, and then is collected and discharged from the return air collection port 22b into the return air flow channel 4 of the refrigerator.

[0065] The area of the return air window 22a is greater than the area of the return air collection port 22b. On the one hand, the return air collection port 22b meets the matching connection between the drawer 2 and the internal return air flow channel 4 of the refrigerator, and on the other hand, the relatively larger return air window 22a can return air, which increases the area range of the return air, to a certain extent, increases the difficulty of the stored objects in the body 21 to block or even obstruct the return air window, thereby reducing the risk of the stored objects blocking the return air port to a certain extent, so that the return air area in the drawer 2 is maintained at a certain level, to ensure the stability of the return air flow and efficiency, and thus to maintain the stability of the refrigeration effect.

[0066] Figure 4 The structure of the refrigerator in the embodiments of the present application is shown; see Figure 2 、 Figure 3 and Figure 4 In some embodiments, a refrigerator is also provided, which comprises a cabinet 3 and the drawer assembly described above. The drawer 2 is movably arranged in the cabinet 3, and the drawer cover plate 1 is arranged in the cabinet 3 and covers the drawer 2.

[0067] Thus, a stable and relatively low-temperature area, i.e., the ice temperature room 31, is formed by the drawer 2 and the drawer cover plate 1, and the heat transfer between the refrigeration room 32 and the ice temperature room 31 is blocked by the drawer cover plate 1, and the risk of icing of the stored items on the drawer cover plate 1 is reduced.

[0068] In some embodiments, in order to maintain the stability of the temperature in the drawer 2, the refrigerator further comprises a temperature sensor 33 arranged in the cabinet 3, and the sensing end of the temperature sensor 33 extends into the drawer 2 when the drawer 2 is in a closed state, so as to accurately monitor the temperature in the drawer 2 and facilitate the control of the temperature in the drawer 2.

[0069] In some embodiments, the temperature sensor 33 can be arranged on the back plate 34 of the cabinet 3, and the distance from the sensing end of the temperature sensor 33 to the inner wall 21a of the drawer 2 close to the back plate 34 is greater than or equal to 10 mm when the drawer 2 is in a closed state, so as to effectively sense the accurate temperature inside the drawer 2, avoid the defect of poor preservation effect caused by the temperature being too high in the ice temperature room 31 due to inaccurate temperature sensing, and also avoid the problem of icing of the items caused by the temperature being too low.

[0070] For example, the distance from the sensing end of the temperature sensor 33 to the inner wall 21a of the drawer 2 close to the back plate 34 can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, or other values greater than 10 mm, which is not specifically limited here.

[0071] In some embodiments, air cooling circulation refrigeration is adopted inside the drawer 2, and therefore the refrigerator further comprises an air inlet 35 and an air duct 35a; the air inlet 35 is arranged on the back plate 34, and the air duct 35a is connected to the air inlet 35 to guide the refrigeration airflow into the drawer 2.

[0072] When the drawer 2 is in a closed state, the distance from the end of the air duct 35a to the inner wall 21a of the drawer 2 close to the back plate 34 is greater than or equal to 15 mm; so as to stably and centrally pass the airflow, which is helpful for the circulation of the airflow in each area of the drawer 2, so as to improve the refrigeration effect.

[0073] Exemplarily, the distance from the end of the air guide pipe 35a to the inner wall 21a of the drawer 2 close to the back plate 34 can be 15 mm, 17 mm, 19 mm, 21 mm, 23 mm, or other values greater than 15 mm, which is not specifically limited here.

[0074] In some examples, the cold air inlet 35 and the return air outlet 36 of the drawer 2 and the temperature sensor 33 can be arranged on the back plate 34 of the refrigerator. The air inlet 35 can be arranged below the drawer cover plate 1, in the upper part of the inner wall 21a of the drawer 2 close to the back plate 34, and the return air outlet 36 can be arranged in the lower part of the inner wall 21a of the drawer 2 close to the back plate 34. When the drawer 2 is pushed into place, the drawer cover plate 1 on the upper part of the drawer 2 and the air duct assembly on the rear part form a closed storage space with the drawer 2.

[0075] In some embodiments, the straight blowing of air into the drawer cover plate 1 will lower the temperature of the drawer cover plate 1. To avoid the food placed on the drawer cover plate 1 from freezing due to excessively low temperature, the angle between the air guide direction of the air guide pipe 35a and the drawer cover plate 1 is 10°-30°, and the air guide direction of the air guide pipe 35a is away from the drawer cover plate 1. Thus, the air inlet is away from the drawer cover plate 1 at an angle of 10°-30°, avoiding direct blowing.

[0076] Exemplarily, the angle between the air guide direction of the air guide pipe 35a and the drawer cover plate 1 can be 10°, 15°, 20°, 25°, 30°, or other values between 10° and 30°, which is not specifically limited here.

[0077] In some embodiments, the drawer 2 can be arranged at the lowest position in the inner chamber of the cabinet 3, so as to facilitate the arrangement of the cold air supply outlet and air duct of the drawer 2.

[0078] In some embodiments, the bottom of the drawer 2 and the refrigeration tank 37 at the bottom of the cabinet 3 have a return air gap 38 of 8 mm-12 mm. The return air of the refrigeration chamber 32 can be used to circulate air at the bottom of the drawer 2, so that air circulation exists at the bottom of the drawer 2 at all times, thereby avoiding the accumulation of temperature difference moisture, to avoid frost or water droplets from the bottom of the drawer 2 from overflowing outside the refrigerator.

[0079] Exemplarily, the return air gap 38 can be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, or other values between 8 mm and 12 mm, which is not specifically limited here.

[0080] In some embodiments, sliding supports can be arranged between the two outer walls of the drawer 2 and the refrigeration tank to push and pull the drawer 2 to open and close.

[0081] The sliding supports can include drawer guide rails made of plastic or metal, and the drawer is mounted on the guide rails to realize forward and backward sliding.
