[0041] Referring to Figure 1 A refrigerator 100 according to an embodiment of the present application can be any one of the mature types of refrigerator 100 products in the prior art, such as a single-door refrigerator, a double-door refrigerator, etc., which can be flexibly selected according to actual needs.

[0042] Please continue to refer to Figure 1 , Figure 2 and Figure 4 For example, the refrigerator 100 includes a cabinet 10, a cold air module 20, an air supply duct 30, and a refrigeration air duct 40.

[0043] The cabinet 10 is the main structure of the refrigerator 100, and is used to load the integrated cold air module 20, the air supply duct 30 and the refrigeration air duct 40. It is easy to understand that the refrigerator 100 should at least include a refrigerator 100 door, an evaporator pan, a control panel box and other functional components. The specific installation structure, function, etc. can be understood with reference to the prior art, and will not be described here.

[0044] The box body 10 is provided with a foaming layer. The foaming layer has the following main functions: heat preservation and insulation: the foaming layer can effectively reduce the loss of the internal temperature of the refrigerator 100, maintain the low temperature state of the interior of the refrigerator 100, thereby prolonging the refrigeration time and reducing energy consumption. Support and bearing: the foaming layer can effectively support and bear the weight of the refrigerator 100, ensuring the structural stability of the refrigerator 100. Moisture and mildew prevention: the foaming layer has certain moisture and mildew resistance, which can effectively prevent the interior of the refrigerator 100 from being damp and mildew, and keep the interior of the refrigerator 100 clean and sanitary.

[0045] During processing, the foaming layer is formed by injecting a mixture of several liquids into the inner wall of the refrigerator 100. The mixture undergoes a chemical reaction to generate high-temperature and high-pressure gas, which is discharged through tiny pores, causing the foaming agent to be evenly filled, and after cooling, a stable solid foaming layer is formed.

[0046] Please continue to refer to Figure 1 and Figure 4 In addition, the box body 10 further forms a refrigeration compartment 11, an intermediate compartment 12 and a freezing compartment 13, the intermediate compartment 12 is arranged between the refrigeration compartment 11 and the freezing compartment 13, and the refrigeration compartment 11 is in airway communication with the freezing compartment 13 through the intermediate compartment 12 to form a return air path. The foaming layer is arranged around the refrigeration compartment 11, the intermediate compartment 12 and the freezing compartment 13 to play a heat preservation role.

[0047] In this application, the refrigeration compartment 11, the intermediate compartment 12 and the freezing compartment 13 are sequentially stacked from top to bottom along the height direction of the refrigerator 100.

[0048] The cold air module 20 is arranged in the freezing compartment 13, and the cold air module 20 is used to generate cold air; the air supply duct 30 is arranged in the foaming layer corresponding to the intermediate compartment 12, and the air inlet of the air supply duct 30 is in communication with the cold air module 20; the refrigeration air duct 40 is arranged in the refrigeration compartment 11, and the air inlet of the refrigeration air duct 40 is in communication with the air outlet of the air supply duct 30, the air outlet of the refrigeration air duct 40 is in communication with the cavity of the refrigeration compartment 11, and the cold air module 20, the air supply duct 30 and the refrigeration air duct 40 cooperate to form an air supply path.

[0049] In summary, the refrigerator 100 of the present embodiment has the following advantages: when the refrigerator 100 is working, the cold air module 20 generates cold air and sends the cold air into the air supply duct 30. The cold air flows along the air supply duct 30 and enters the refrigeration air duct 40. Then, the cold air flows out of the refrigeration air duct 40 and enters the refrigeration compartment 11. Then, the cold air flows into the intermediate compartment 12 from the refrigeration compartment 11, so as to refrigerate the refrigeration compartment 11 and the intermediate compartment 12, and meet the food storage requirements. Finally, the cold air flows back to the freezing compartment 13, and the air circulation is completed. Since the foamed layer is arranged in the cabinet 10, and the air supply duct 30 is arranged in the foamed layer corresponding to the intermediate compartment 12, the cold air flowing into the air supply duct 30 does not need to be directly sent into the intermediate compartment 12. Therefore, the special air door 60, the heat preservation foam, the sensor and other components for controlling the flow direction of the intermediate compartment 12 can be omitted, the number of installed components is greatly reduced, and the volume occupation is reduced. In addition, the air supply duct 30 arranged in the foamed layer avoids directly occupying the volume of the intermediate compartment 12, so that the volume of the intermediate compartment 12 can be more fully utilized, and the refrigerator 100 can provide more product volume for the user, and the user experience and product competitiveness are improved.

[0050] Please continue to refer to Figures 3 to 5 On the basis of the above embodiment, the refrigerator 100 further comprises a refrigeration partition plate 50. The refrigeration partition plate 50 is arranged in the cabinet 10 and is arranged between the refrigeration compartment 11 and the intermediate compartment 12. The refrigeration partition plate 50 is provided with a ventilation hole 51. The ventilation hole 51 communicates the refrigeration compartment 11 and the intermediate compartment 12.

[0051] Generally, the temperature range inside the refrigeration compartment 11 is different from the temperature range inside the intermediate compartment 12. For example, the temperature range inside the refrigeration compartment 11 is generally 2°C to 4°C, and the temperature range inside the intermediate compartment 12 is generally 3°C to 8°C. Therefore, the two compartments are suitable for storing products with different temperature requirements. Therefore, by arranging the refrigeration partition plate 50, the cold quantity can be blocked to a certain extent to maintain the required temperature environment of the refrigeration compartment 11 and the intermediate compartment 12.

[0052] By arranging the ventilation hole 51 on the refrigeration partition plate 50, a part of the cold air flowing into the refrigeration compartment 11 can flow into the intermediate compartment 12 to form a required low-temperature environment in the intermediate compartment 12. This structural design can avoid arranging the air door 60 and other heat preservation components for the intermediate compartment 12, and can avoid wasting the volume of the intermediate compartment 12.

[0053] For example, the refrigeration partition plate 50 in the present application is a single-wall-thickness plastic partition plate, which has a simple structure, occupies a small volume, and has a low cost.

[0054] Please continue to refer to Figure 4In yet another embodiment, the refrigerator 100 further comprises a damper 60, which is arranged in the air cavity of the air supply air duct 30 and is configured to control the flow of cold air from the air supply air duct 30 to the refrigeration air duct 40.

[0055] It is easy to understand that the damper 60 has a closed state and an open state. When in the closed state, the cold air cannot flow from the air supply air duct 30 to the refrigeration air duct 40; when in the open state, the cold air can continuously flow from the air supply air duct 30 to the refrigeration air duct 40, and then into the refrigeration compartment 11 and the intermediate compartment 12, so as to meet the needs of creating a low-temperature storage environment in the refrigeration compartment 11 and the intermediate compartment 12.

[0056] Further, by controlling the opening size of the damper 60, the cold air flow can be controlled, and the temperature of the refrigeration compartment 11 and the intermediate compartment 12 can be dynamically adjusted to ensure the temperature stability of the two compartments. For example, when the door of the refrigerator 100 is opened to access the items in the refrigeration compartment 11 and / or the intermediate compartment 12, the cold air in the compartment will leak, which will cause the temperature of the compartment to rise. At this time, the opening of the damper 60 can be increased to make more cold air flow into the refrigeration compartment 11 and / or the intermediate compartment 12 at a faster speed, so that the compartment can recover to the set low-temperature environment more quickly, and the food can be prevented from being damaged due to high temperature.

[0057] For example, the damper 60 can adopt any one of a rotary damper, a linear moving damper, etc. In the present application, the damper 60 adopts a single damper with a size of 70mm*25mm.

[0058] Please continue to refer to Figure 4 Further, the damper 60 is arranged at the air outlet of the air supply air duct 30, and the damper 60 is located below the refrigeration partition 50. By sinking the damper 60 into the air supply air duct 30 and placing it below the refrigeration partition 50, the damper 60 can be avoided to be placed in the refrigeration air duct 40, and the refrigeration air duct 40 needs to be additionally left out of space to wrap the damper 60 and the increased foam at the damper 60, which effectively avoids the influence on the volume of the refrigeration compartment 11. In addition, the damper 60 is arranged close to the refrigeration air duct 40, which can more effectively and accurately control the on-off and flow of the cold air flowing into the refrigeration air duct 40.

[0059] In addition, on the basis of any of the above embodiments, the inner wall of the intermediate compartment 12 is provided with an intermediate compartment liner, the intermediate compartment liner is arranged at the front side of the foaming layer, the intermediate compartment liner is provided with a mounting groove corresponding to the rear part of the rear side of the refrigerator 100, and the air supply air duct 30 is arranged in the mounting groove and located between the intermediate compartment liner and the foaming layer. By clamping the groove side wall of the mounting groove and the outer wall of the air supply air duct 30, the installation stability of the air supply air duct 30 is improved.

[0060] Further, the air supply air duct 30 is installed with the refrigeration partition 50. Specifically, the air supply air duct 30 is installed and fixed with the refrigeration partition 50 at one end close to the refrigeration air duct 40, and the installation mode can be at least one of clamping, screwing, bonding, magnetic attraction connection, riveting and the like, so that the air supply air duct 30 is limited by the refrigeration partition 50, further improving the installation stability of the air supply air duct 30, avoiding loosening and displacement during work due to air flow, and further avoiding long noise, affecting the quietness of the refrigerator 100.

[0061] In the present application, the air supply air duct 30 and / or the refrigeration air duct 40 are made of foam material, which is easy to process and has low cost, and good heat preservation, avoiding excessive temperature drop of cold air and affecting the refrigeration effect on the refrigeration compartment 11 and the intermediate compartment 12. Of course, in other optional embodiments, the air supply air duct 30 and the refrigeration air duct 40 can also be made of other heat preservation materials, which are also within the protection scope of the present application, and will not be repeated here.

[0062] Please continue to refer to Figure 3 and Figure 4 In addition, the refrigerator 100 further comprises a foamed bubble layer 70, which is arranged between the intermediate compartment 12 and the freezing compartment 13 in the cabinet 10. Compared with the traditional foamed partition, the foamed bubble layer 70 not only has better heat preservation performance and can better maintain the low temperature environment required by the intermediate compartment 12 and the freezing compartment 13, but also the thickness of the foamed bubble layer 70 can be reduced by 5mm-10mm, thereby reducing the volume occupation and increasing the product volume provided to the user.

[0063] Please continue to refer to Figure 3 and Figure 4 In one embodiment, the cold air module 20 comprises an evaporator 21, a freezing air duct 22 and a fan 23, the evaporator 21 is in communication with the air inlet of the freezing air duct 22, the air outlet of the freezing air duct 22 is in communication with the air inlet of the air supply air duct 30, and the fan 23 is arranged in the freezing air duct 22 and on one side of the air outlet of the freezing air duct 22. When working, the evaporator 21 generates cold air and discharges the cold air into the freezing air duct 22, and the fan 23 operates to generate driving force, so that the cold air in the freezing air duct 22 can be sent out from the air outlet, so that the cold air can continuously flow into the air cavity of the air supply air duct 30. Arranging the fan 23 on one side of the air outlet of the freezing air duct 22 can make the cold air enter the air supply air duct 30 laterally in the form of flinging under the centrifugal force of the fan 23, prolong the air supply path, and avoid wind noise caused by the cold air flowing not in time.

[0064] Further, the fan 23 is arranged above the front side of the evaporator 21, and the shortest distance between the fan 23 and the evaporator 21 is not less than 30 mm. In this way, a safe distance is kept between the blades of the fan 23 and the evaporator 21, so that icing of the blades of the fan 23 due to overcooling is avoided.

[0065] For example, the evaporator 21 has multiple rows of pipes arranged side by side and spaced apart along the height direction of the evaporator 21 (i.e. the height direction of the refrigerator 100), and the uppermost row of pipes is arranged closest to the fan 23, and the distance between the uppermost row of pipes and the blades of the fan 23 is greater than 30 mm, so as to prevent the blades from being too close to the pipes and icing due to overcooling, thereby affecting the normal operation of the fan 23.

[0066] Please continue to refer to Figure 2 In yet another embodiment, the refrigerator 100 further comprises a return air duct 80 arranged in the cabinet 10, the intermediate compartment 12 is provided with a return air opening 121, the return air opening 121 is in communication with one end of the return air duct 80, and the other end of the return air duct 80 is connected to the evaporator 21. After the cold air reaching the intermediate compartment 12 creates a low-temperature refrigeration environment for the intermediate compartment 12, the cold air can flow back to the evaporator 21 through the return air duct 80, so as to form a cold air circulation flow path in the refrigerator 100, thereby ensuring the refrigeration effect of each compartment.

[0067] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0068] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
