[0055] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0056] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the corresponding device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0057] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0058] Furthermore, it should be noted that in the description of this utility model, the terms "coldness" and "heat" are two descriptions of the same physical state. That is, the higher the "coldness" of a target object (e.g., evaporator, air, condenser, etc.), the lower its "heat," and vice versa. A target object absorbs "coldness" while releasing "heat," and releases "coldness" while absorbing "heat." A target object retains "coldness" or "heat" to maintain its current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon; that is, a target object (e.g., evaporator) absorbs heat while refrigerating.

[0059] The following text will use the refrigerator as an example to provide a detailed explanation of the refrigerator door.

[0060] like Figure 1 and Figure 2 As shown, in this utility model, the refrigerator 001 includes a cabinet 100, a door 200, an evaporator 300, and a cooling fan 400. The door 200 is installed on the cabinet 100 for opening and closing the cabinet 100. The evaporator 300 is installed inside the cabinet 100 for providing cooling to the interior space of the cabinet 100. The cooling fan 400 is installed inside the cabinet 100 for delivering the air cooled by the evaporator 300 to the interior space of the cabinet 100.

[0061] It should be noted that although not shown in the figure, the refrigerator 001 of this utility model also includes components such as a compressor and a condenser. Since these components are not related to or not directly related to the technical problem to be solved by this utility model, and are well known to those skilled in the art, this utility model will not describe them in detail.

[0062] like Figure 2As shown, in this invention, the housing 100 defines a freezer compartment 101, a refrigerator compartment 102, a variable-temperature compartment 103, and a refrigeration space 104. The freezer compartment 101 provides a low temperature (e.g., less than -10°C) for food placed within it to freeze it. The refrigerator compartment 102 provides a higher temperature (e.g., 2°C to 4°C) for food placed within it to prevent freezing and provide a low-temperature preservation environment. The variable-temperature compartment 103 typically has a temperature between the freezer compartment 101 and the refrigerator compartment 102, used for soft freezing of food. That is, the temperature of the food is brought close to its freezing point, but it does not freeze. Of course, those skilled in the art can adjust the temperature of the variable-temperature compartment 103 to match the temperature of either the freezer compartment 101 or the refrigerator compartment 102, so that it can be used as either the freezer compartment 101 or the refrigerator compartment 102. The refrigeration space 104 can be used to house an evaporator 300 and a refrigeration fan 400.

[0063] like Figures 2 to 4 As shown, in this utility model, the freezer compartment 101 is equipped with a freezer air inlet 1011 and a freezer air return outlet 1012 that are respectively connected to the refrigeration space 104; the refrigerator compartment 102 is equipped with a refrigerator air inlet 1021 and a refrigerator air return outlet 1022 that are respectively connected to the refrigeration space 104; and the variable temperature compartment 103 is equipped with a variable temperature air inlet 1031 that is connected to the freezer compartment 101 and a variable temperature air return outlet 1032 that is connected to the refrigeration space 104.

[0064] like Figures 2 to 4 As indicated by the arrows, when the refrigeration fan 400 is operating, there is a circulating airflow between the freezer compartment 101 and the refrigeration space 104. This circulating airflow carries the cooling energy generated by the evaporator 300 in the refrigeration space 104 into the freezer compartment 101, thus cooling the freezer compartment 101. Similarly, there is a circulating airflow between the refrigerator compartment 102 and the refrigeration space 104. This circulating airflow carries the cooling energy generated by the evaporator 300 in the refrigeration space 104 into the refrigerator compartment 102, thus cooling the refrigerator compartment 102.

[0065] like Figure 2 As shown, in this utility model, the refrigerator 001 may further include a variable temperature fan 500, which is used to drive the air in the freezer compartment 101 to flow through the variable temperature compartment 103 to the cooling space 104 (e.g., Figures 2 to 4 (As indicated by the arrow in the image) to ensure that the variable temperature chamber 103 can be properly cooled.

[0066] Furthermore, the variable temperature air inlet 1031 is located at the refrigeration return air inlet 1012 to reduce the air pressure difference between the variable temperature air inlet 1031 and the variable temperature return air inlet 1032 during the operation of the refrigeration fan 400, and to prevent air in the refrigeration chamber 101 from flowing to the variable temperature chamber 103.

[0067] Those skilled in the art will understand that, in the refrigerator 001 of this invention, when the variable temperature fan 500 is not running, it insulates the variable temperature compartment 103. Furthermore, when the refrigeration fan 400 is running, because the pressure difference between the variable temperature air inlet 1031 and the variable temperature air return vent 1032 is small, convection will not form due to the pressure difference, preventing cold air from entering the variable temperature compartment 103 from the freezer compartment 101. This improves the insulation effect of the refrigerator 001 on the variable temperature compartment 103. This is especially true when the pressure difference between the variable temperature air inlet 1031 and the variable temperature air return vent 1032 is zero.

[0068] like Figure 2 As shown, in this utility model, the variable temperature air inlet 1031 can be set at one end of the refrigeration return air inlet 1012 to ensure that the air flowing to the variable temperature chamber 103 will not affect the air flow in the refrigeration chamber 101.

[0069] Those skilled in the art can, based on the technical principles of this utility model, determine the optimal positions of the variable temperature air inlet 1031, variable temperature air return 1032, and refrigeration air return 1022 for each refrigerator 001 by simulation, on the basis of setting the variable temperature air inlet 1031 at the freezer return air inlet 1012.

[0070] like Figures 2 to 4 As shown, in this utility model, the variable temperature return air vent 1032 is connected to the cold storage compartment 102 and is close to the cold storage return air vent 1022.

[0071] Furthermore, the refrigerated return air vent 1022 is located at the end of the refrigerated compartment 102 near the variable temperature compartment 103, thereby shortening the distance between the variable temperature return air vent 1032 and the refrigerated return air vent 1022. This allows air flowing from the variable temperature compartment 103 into the refrigerated compartment 102 to quickly flow through the refrigerated return air vent 1022 into the refrigerated space 104. Simultaneously, it reduces the air resistance of the air flowing out of the variable temperature compartment 103 within the refrigerated compartment 102, allowing the pressure difference between the variable temperature return air vent 1032 and the variable temperature air inlet 1031 to tend towards uniformity.

[0072] Those skilled in the art will understand that, in this way, when the variable temperature compartment 103 needs cooling, the variable temperature fan 500 can force the cooler air in the freezer compartment 101 to flow into the variable temperature compartment 103, thereby cooling the variable temperature compartment 103. It can also force the air in the variable temperature compartment 103 to flow into the refrigerator compartment 102, thereby cooling the refrigerator compartment 102, thus achieving secondary utilization of cooling capacity.

[0073] like Figures 2 to 4 As shown, in this utility model, the freezer compartment 101 is located on the front side of the refrigeration space 104, the refrigerator compartment 102 and the variable temperature compartment 103 are located on one side of the freezer compartment 101 in the horizontal (left-right direction), and the variable temperature compartment 103 is located on the bottom side of the refrigerator compartment 102.

[0074] In addition, those skilled in the art can make appropriate adjustments to the arrangement of the freezer compartment 101, the refrigerator compartment 102, the variable temperature compartment 103 and the refrigeration space 104 as needed, and can omit one of the compartments as needed.

[0075] For example, the freezer compartment 101 and the variable temperature compartment 103 can both be located on the bottom side of the refrigerator compartment 102, and the freezer compartment 101 and the variable temperature compartment 103 can be arranged laterally.

[0076] For example, the refrigerator compartment 102 can be omitted, and only the freezer compartment 101, the variable temperature compartment 103, and the refrigeration space 104 can be retained.

[0077] The following reference Figures 5 to 21 The following is a further example illustrating the refrigerator 001 of this utility model.

[0078] like Figures 5 to 7 As shown, in some embodiments of this utility model, the cabinet 100 further includes a freezer inner liner 110, a refrigerator inner liner 120, a back panel 130, and a variable temperature air intake component 140. The refrigerator 001 also includes a partition assembly 600 and an optional drawer 700.

[0079] The partition assembly 600 is installed horizontally or at an angle into the refrigerator liner 120 to separate the refrigerator compartment 102 and the variable temperature compartment 103 within the refrigerator liner 120. The drawer 700 is installed in a pull-out manner into the variable temperature compartment 103 below the partition assembly 600.

[0080] like Figure 5 and Figure 6As shown, in some embodiments of this utility model, the bottom of the rear sidewall of both the freezer inner liner 110 and the refrigerator inner liner 120 has a stepped structure to avoid components such as the compressor and condenser inside the cabinet 100. This stepped structure also gives both the freezer inner liner 110 and the refrigerator inner liner 120 an inclined section 122 that slopes forward from top to bottom. The partition assembly 600 abuts against this inclined section 122.

[0081] The back panel 130 is installed in the freezer liner 110 to divide the freezer liner 110 into a freezer compartment 101 and a refrigeration space 104 located behind the freezer compartment 101.

[0082] Furthermore, although not explicitly shown in the figure, the side walls of the freezer inner liner 110 and the refrigerator inner liner 120, which are close to each other, are respectively provided with connecting openings at positions aligned with the refrigeration space 104 in their respective front-rear directions, so as to connect the refrigerator compartment 102 with the refrigeration space 104. A channel component (such as a rectangular tube, round tube, or irregularly shaped tube) can be installed at this connecting opening to connect the refrigerator compartment 102 with the refrigeration space 104. For example, Figure 6 The component shown has a refrigerated return air vent 1022.

[0083] from Figure 7 and Figure 8 It is not difficult to see that a refrigeration return air vent 1012 is formed between the bottom end of the back panel 130 and the peripheral wall of the freezer compartment 101 (i.e., the freezer inner liner 110), and a refrigeration air inlet 1011 is formed between the top end of the back panel 130 and the peripheral wall of the freezer compartment 101 (i.e., the freezer inner liner 110).

[0084] from Figure 7 As can be seen, the refrigeration return air inlet 1012 is set as a strip-shaped inlet, and the variable temperature air inlet 1031 is formed at one end of the length direction (left and right direction) of the refrigeration return air inlet 1012.

[0085] like Figure 8 As shown, in some embodiments of this utility model, the bottom end of the back plate 130 is provided with a clearance notch 1301 for avoiding the variable temperature air inlet component 140. The variable temperature air inlet component 140 abuts against the clearance notch 1301 so that the variable temperature air inlet 1031 is connected to the refrigeration return air inlet 1012.

[0086] Continue reading Figure 8 The bottom of the back panel 130 is provided with a tongue portion 131 extending into the freezer compartment 101, and a clearance notch 1301 is formed on the tongue portion 131. Furthermore, a strip-shaped freezer return air vent 1012 is formed between the tongue portion 131 and the rear side wall of the freezer inner liner 110.

[0087] Furthermore, although not shown in the figure, mounting openings are respectively provided on the side walls of the freezer inner liner 110 and the refrigerator inner liner 120 that are close to each other. The variable temperature air inlet component 140 is embedded in the mounting opening on the freezer inner liner 110 and connects the freezer inner liner 110 and the refrigerator inner liner 120 directly or through other channel components. Specifically, it connects the freezer compartment 101 and the variable temperature compartment 103. For this purpose, the variable temperature air inlet component 140 defines a variable temperature air inlet 1031 (e.g., ...). Figure 9 and Figure 10 (As shown).

[0088] like Figure 9 and Figure 10 As shown, the variable temperature air inlet component 140 is provided with a fitting part 141 and an overlapping part 142 on the side near the back plate 130. The fitting part 141 is inserted into the clearance notch 1301, and the overlapping part 142 overlaps with the tongue plate part 131.

[0089] like Figure 11 and Figure 12 As shown, the fitting portion 141 is inserted into the clearance notch 1301 and abuts against the edge (peripheral wall) of the clearance notch 1301, and the overlapping portion 142 abuts against the side of the tongue portion 131 away from the freezer inner liner 110, so that the variable temperature air inlet component 140 fixed to the freezer inner liner 110 can fix the bottom end of the back plate 130 and prevent the bottom end of the back plate 130 from loosening. At the same time, it also ensures the sealing of the freezer return air vent 1012.

[0090] like Figures 9 to 12 As shown, in some embodiments of this utility model, a stop plate 143 is provided on the variable temperature air inlet component 140 so that the variable temperature air inlet component 140 abuts against the inner wall of the refrigeration liner 110 through the stop plate 143, thereby improving the connection strength between the variable temperature air inlet component 140 and the refrigeration liner 110.

[0091] like Figures 13 to 14 As shown, in some embodiments of this utility model, the door 200 of the refrigerator 001 includes a body 210, an annular sealing ring 220, and a transverse sealing strip 230. The annular sealing ring 220 is disposed on the inner side of the body 210 along the circumferential edge of the body 210, and is used to abut against the cabinet 100 of the refrigerator 001 to achieve a seal between the cabinet 100 and the door 200. The transverse sealing strip 230 is disposed on the inner side of the body 210 along the transverse direction of the body 210 to abut against the partition assembly 600 on the refrigerator 001.

[0092] Furthermore, the transverse sealing strip 230 protrudes inward toward the body 210 (the side closest to the cabinet 100) at a greater height than the annular sealing ring 220 protrudes inward toward the body 210, ensuring that the door 200 and the partition assembly 600 can be sealed by the transverse sealing strip 230. This effectively eliminates the gap between the partition assembly 600 and the door 200, thereby preventing temperature cross-contamination between the refrigerated compartment 102 and the variable temperature compartment 103. Especially when the variable temperature compartment 103 requires insulation, the variable temperature compartment 103 and the refrigerated compartment 102 are only connected through the variable temperature return air vent 1032, making air convection difficult to form, thus effectively preventing temperature cross-contamination between the two.

[0093] like Figure 14 As shown, in some embodiments of this utility model, the body 210 is provided with an annular groove 211 and a transverse groove 212, the annular sealing ring 220 is snapped into the annular groove 211, and the transverse sealing strip 230 is snapped into the transverse groove 212.

[0094] Furthermore, the transverse groove 212 and the annular groove 211 can be connected to facilitate the processing and demolding of the body 210.

[0095] like Figure 15 As shown, in some embodiments of this utility model, the transverse sealing strip 230 includes a fixing part 231 fixedly connected to the body 210 and a sealing part 232 disposed inside the fixing part 231.

[0096] like Figure 14 and Figure 15 As shown, the fixing part 231 is located inside the annular sealing ring 220 in the transverse direction of the door body 200, and the fixing part 231 is engaged in the transverse groove 212 to fix the transverse sealing strip 230 to the body 210.

[0097] like Figure 13 and Figure 15 As shown, the two ends of the sealing part 232 extend laterally to the outside of the fixing part 231 and overlap with the inside of the annular sealing ring 220 to ensure a seal between the door body 200 and the partition assembly 600.

[0098] like Figures 16 to 21 As shown, in some embodiments of this utility model, the partition assembly 600 is provided with an air inlet duct 601, an air inlet 602 corresponding to and connected to the air inlet duct 601, an air outlet 603 corresponding to and connected to the air inlet duct 601, an air outlet 604, an upstream air outlet 605 corresponding to and connected to the air outlet duct 604, and a downstream air outlet 606 corresponding to and connected to the air outlet duct 604.

[0099] The air inlet duct 601 is formed within the partition assembly 600. The air inlet 602 communicates with the air inlet duct 601 and is disposed on one side of the partition assembly 600 along a first direction x (left-right direction), which is perpendicular to the thickness direction z of the partition assembly 600. The air outlet 603 communicates with the air inlet duct 601 and is disposed on one side along the thickness direction z. The air outlet 603 includes at least one set of micropores 6031 to allow air entering the air inlet duct 601 from the air inlet 602 to be quickly and uniformly blown out through the micropores 6031.

[0100] Furthermore, the air inlet 602 corresponding to the air inlet 601 is connected to the variable temperature air inlet 1031, and the air outlet 603 corresponding to the air inlet 601 is connected to the variable temperature chamber 103, so as to introduce cold air in the freezer chamber 101 into the variable temperature chamber 103 through the air inlet 601.

[0101] like Figure 16 and Figure 19 As shown, the air duct outlet 603 is located near one end of the partition assembly 600 in the second direction y (front-to-back direction), that is, on the bottom side of the front part of the partition assembly 600. The second direction y, the first direction x, and the thickness direction z are perpendicular to each other. The air duct outlet 603 includes three sets of micropores 6031, and the three sets of micropores 6031 are distributed in a triangular pattern to allow cold air to be blown evenly from the three sets of micropores 6031 into the variable temperature chamber 103.

[0102] from Figure 16 and Figure 19 As can be seen, each group of micropores 6031 is generally a strip parallel to the first direction x, so that the cold air can cover the front of the variable temperature chamber 103 as much as possible on the left, right and upper sides.

[0103] like Figure 16 , Figure 17 , Figures 19 to 21 As shown, the air outlet duct 604 is located at the other end of the partition assembly 600 in the second direction y (front-back direction) to allow air to flow between the two sides of the partition assembly 600. That is, air is blown through the air outlet duct 604 to the front of the temperature-controlled compartment 103, flows to the rear of the temperature-controlled compartment 103, and then flows through the rear of the temperature-controlled compartment 103 to the refrigeration compartment 102.

[0104] like Figure 19 and Figure 21 As shown, the upstream air vent 605 and the downstream air vent 606 are located at both ends of the air outlet duct 604 and are formed on two adjacent sides of the partition assembly 600. Specifically, the upstream air vent 605 is formed on the bottom surface of the partition assembly 600 so that the upstream air vent 605 communicates with the variable temperature compartment 103; the downstream air vent 606 is formed on the rear side of the partition assembly 600 so that the downstream air vent 606 communicates with the cold storage compartment 102.

[0105] Furthermore, in some embodiments of this utility model, the downstream air outlet 606 serves as a variable temperature return air outlet 1032 and is located on the rear side of the partition assembly 600.

[0106] like Figure 16 and Figure 17 As shown, in some embodiments of this utility model, the partition assembly 600 includes a duct plate 610, a duct shielding assembly 620, a bottom shell 630, a top shell 640, a partition fan 651, a fan fixing component 652, a duct steering component 653, a sealing component 660, a temperature sensor 670, a display module 681, and a display diaphragm 682.

[0107] exist Figures 16 to 21 In the illustrated embodiment, the baffle fan 651 is equivalent to the variable temperature fan 500 described above. In other words, the baffle fan 651 and the variable temperature fan 500 refer to the same fan, but they correspond to different illustrated embodiments, to facilitate understanding by those skilled in the art.

[0108] Furthermore, in some embodiments of this utility model, those skilled in the art will understand that at least one of the following components may be omitted: air duct plate 610, air duct shielding assembly 620, bottom shell 630, top shell 640, partition fan 651, fan fixing component 652, air duct deflector 653, sealing component 660, temperature sensor 670, display module 681, and display diaphragm 682. For example, display module 681 and display diaphragm 682 may be omitted. As another example, partition fan 651 and fan fixing component 652 may be omitted, and a circulating fan may be arranged in the variable temperature chamber 103 or at the refrigeration return air inlet 1012 of the refrigeration chamber 101.

[0109] like Figure 16 and Figure 17 As shown, the air inlet duct 601 and the air outlet duct 604 are formed within the duct plate 610. The duct inlet 602, the duct outlet 603, and the upstream air outlet 605 are formed on the bottom shell 630, and the downstream air outlet 606 is formed on the top shell 640. The duct plate 610 has an air duct opening 6101 on the side of the air inlet duct 601 near the bottom shell 630, through which the air duct shielding assembly 620, the baffle fan 651, and the fan fixing member 652 are embedded (e.g., ...) within the air inlet duct 601. Figure 20 (As shown).

[0110] Furthermore, the fan fixing component 652 can be interference-fitted with the air inlet duct 601 to fix the baffle fan 651 to the duct plate 610, preventing the baffle fan 651 from falling out of the air inlet duct 601 during the assembly of the baffle assembly 600.

[0111] Correspondingly, the air duct shielding assembly 620 can also be interference-fitted with the air inlet duct 601.

[0112] like Figure 16 As shown, the air duct plate 610 has a stepped surface 611 (higher than the deepest bottom surface of the air inlet duct 601) inside the air inlet duct 601, so that it can abut against the air duct blocking component 620 through the stepped surface 611 to ensure that the air inlet duct 601 is not blocked by the air duct blocking component 620.

[0113] like Figure 16 and Figure 17 As shown, in some embodiments of this utility model, the bottom shell 630 is provided with an outward protrusion 631 on the side near the freezer inner liner 110, which protrudes away from the air duct plate 610. The air duct inlet 602 is formed on the side of the outward protrusion 631 near the freezer inner liner 110 to ensure that the partition assembly 600 can receive cold air from the freezer compartment 101.

[0114] Continue reading Figure 16 and Figure 17 In some embodiments of this utility model, a slot 634 is provided on the peripheral wall of the bottom shell 630, and a protrusion 641 is provided on the peripheral wall of the top shell 640. The protrusion 641 is inserted into the slot 634, thereby fixing the top shell 640 and the bottom shell 630 together.

[0115] In addition, in other embodiments of this utility model, those skilled in the art may, as needed, set the slot 634 on the top shell 640 and the insertion protrusion 641 on the bottom shell 630.

[0116] Continue reading Figure 16 and Figure 17 In some embodiments of this utility model, a sensor fixing structure 632 is provided on the side of the bottom shell 630 facing the air duct plate 610. The sensor fixing structure 632 is used to install the temperature sensor 670. The temperature sensor 670 can be fixed to the sensor fixing structure 632 by any feasible method such as adhesive, snap-fit, or clamping.

[0117] Furthermore, the bottom shell 630 is also provided with a ventilation hole 6301 that penetrates the sensor fixing structure 632, so that air flows from the outside of the bottom shell 630 to the sensor fixing structure 632 through the ventilation hole 6301.

[0118] from Figure 16 and Figure 17As can be seen, the temperature sensor 670 and the ventilation hole 6301 are arranged between the air duct outlet 603 and the air duct inlet 602 so that the air blown out of the air duct outlet 603 bypasses the temperature sensor 670 and flows to the air duct outlet 603, preventing it from blowing directly onto the temperature sensor 670, thereby improving the accuracy of the temperature sensor 670 in detecting the temperature of the variable temperature chamber 103.

[0119] from Figure 16 and Figure 17 As can be seen from this, in some embodiments of the present invention, two temperature sensors 670 can be installed in the partition assembly 600 to determine the maximum value in the variable temperature chamber 103 by means of the average, minimum or maximum value detected by the two temperature sensors 670.

[0120] Furthermore, based on the bottom shell 630 and top shell 640 being connected together by inserting protrusion 641 and slot 634, the bottom shell 630 and top shell 640 can be fixed together by interference fit or adhesive bonding between inserting protrusion 641 and slot 634, or by screw connection, welding and other methods.

[0121] like Figure 19 and Figure 21 As shown, with the partition assembly 600 assembled, the top shell 640 is located on the top side of the air duct plate 610, and the bottom shell 630 is located on the bottom side of the air duct plate 610, thus the top shell 640 and the bottom shell 630 clamp the air duct plate 610 in the middle.

[0122] like Figures 16 to 18 and Figure 20 As shown, in some embodiments of this utility model, the air inlet duct 601 is configured in a U-shape. Furthermore, the duct shielding assembly 620 includes a T-shaped shielding member 621 and a T-shaped shielding member 622 spaced apart within the air inlet duct 601. The bottom shell 630 has two sets of micro-holes 6031 spaced apart at the interval between the T-shaped shielding member 621 and the T-shaped shielding member 622, and a set of micro-holes 6031 at the end of the T-shaped shielding member 622 away from the T-shaped shielding member 621, to ensure the air delivery function of the air inlet duct 601.

[0123] like Figure 18 As shown, in some embodiments of this utility model, the end of the T-shaped shield 621 near the T-shaped shield 622 may be provided with a first arc-shaped surface 6211 inclined towards the bottom shell 630 to reduce air resistance. Furthermore, the end of the T-shaped shield 622 away from the T-shaped shield 621 may be provided with a second arc-shaped surface 6221 inclined towards the bottom shell 630 to reduce air resistance.

[0124] from Figure 16 and Figure 17As can be seen from the above, in some embodiments of this utility model, the partition fan 651 is a centrifugal fan and the fan fixing component 652 is an annular component to ensure that the partition fan 651 can draw in air.

[0125] In addition, in other embodiments of this utility model, those skilled in the art can also, as needed, set the partition fan 651 to any other feasible fan, such as an axial flow fan.

[0126] like Figure 16 , Figure 17 , Figures 19 to 21 As shown, in some embodiments of this utility model, the sealing member 660 is configured in a U-shape, such that the sealing member 660 includes a transverse portion 661 and longitudinal portions 662 located at both ends of the transverse portion 661. This allows the sealing member 660 to abut against the rear side wall of the refrigerator inner liner 120 via the transverse portion 661, and against the left and right side walls of the refrigerator inner liner 120 via the longitudinal portions 662. The transverse portion 661 is located on the bottom surface of the partition assembly 600, and the two longitudinal portions 662 are located on the left and right sides of the partition assembly 600.

[0127] Go back and refer to Figure 5 In some embodiments of this invention, the rear sidewall of the refrigerator liner 120 includes an inclined section 122 that slopes forward from top to bottom. After the partition assembly 600 is installed onto the refrigerator liner 120, the inclined section 122 abuts against the transverse portion 661.

[0128] like Figure 16 As shown, in some embodiments of this utility model, a concave surface 6302 is provided on the bottom side of the rear part of the bottom shell 630, and a transverse portion 661 is disposed within the concave surface 6302. Further, arc-shaped chamfered surfaces 6303 are respectively provided between the two ends of the concave surface 6302 and the left and right side walls of the bottom shell 630, and the junction of the transverse portion 661 and the longitudinal portion 662 is fitted with the arc-shaped chamfered surfaces 6303.

[0129] Furthermore, the ratio of the thickness of the sealing member 660 to the depth of the concave surface 6302 is selected from any value from 1.5 to 3, such as 1.5, 1.8, 2, 2.5, 2.8, 3, etc., to ensure that the sealing member 660 has sufficient compression after the partition assembly 600 is installed in the refrigerator liner 120, thereby ensuring the seal between the rear end of the partition assembly 600 and the refrigerator liner 120.

[0130] Therefore, in some embodiments of this utility model, the sealing member 660 can also be a component made of foam. Alternatively, those skilled in the art can, as needed, set the sealing member 660 as a hollow rubber strip or latex strip.

[0131] Furthermore, at least the bottom shell 630 is bonded to the sealing member 660 to ensure that the sealing member 660 can be transported, installed, etc. together with the partition assembly 600.

[0132] like Figure 17 As shown, in some embodiments of this utility model, a mounting groove 6102 is provided on the side of the air duct plate 610 near the top shell 640 to mount the display module 681 into the mounting groove 6102. A display diaphragm 682 is mounted on the top shell 640 and aligned with the display module 681. Specifically, the top shell 640 has an area for fixing the display diaphragm 682; this area can be a hollow area so that the user can view the content displayed by the display module 681 through the display diaphragm 682. The display module 681 may include a light assembly and / or a display screen. The display diaphragm 682 may be a plastic sheet or a glass sheet.

[0133] The following reference Figures 16 to 21 The assembly process of the partition assembly 600 in some embodiments of this utility model will be briefly described below. However, it should be noted that the assembly sequence of the partition assembly 600 described below is not unique, and those skilled in the art can make appropriate adjustments as needed.

[0134] First, the air duct shielding assembly 620 is embedded into the air inlet duct 601 of the air duct plate 610, and the baffle fan 651 and the fan fixing member 652 are also sequentially embedded into the air inlet duct 601 of the air duct plate 610 (e.g. Figure 20 (As shown).

[0135] Next, the airflow steering component 653 is embedded in the protrusion 631 of the base shell 630. The temperature sensor 670 is then installed at the sensor fixing structure 632 of the base shell 630.

[0136] from Figure 16 and Figure 17 As can be seen, the airflow deflector 653 has a deflection channel (not marked in the figure) defined inside, and the inlet of the deflection channel is located on the left side of the airflow deflector 653, and the outlet of the deflection channel is located on the top side of the airflow deflector 653, so as to transform the transversely flowing air into air flowing upward toward the baffle fan 651.

[0137] Then, align and attach the bottom shell 630 to the air duct plate 610.

[0138] Subsequently, the display module 681 is installed into the mounting slot 6102 of the air duct plate 610, and the display diaphragm 682 is fixed to the top shell 640 by means of bonding, welding, interference fit, snap-fit, etc.

[0139] Subsequently, the top shell 640 is fastened onto the top side of the duct plate 610 and inserted together with the bottom shell 630, so that the duct shielding assembly 620 is clamped by the bottom shell 630 and the duct plate 610, and the baffle fan 651, the fan fixing part 652 and the airway deflector 653 are also clamped by the bottom shell 630 and the duct plate 610.

[0140] Finally, the sealing member 660 is bonded to the base 630 and / or the outer casing.

[0141] Furthermore, to ensure that the "duct shielding assembly 620," "partition fan 651, fan fixing component 652, and airflow deflector 653" are clamped between the bottom shell 630 and the duct plate 610, those skilled in the art may, as needed, make both the duct plate 610 and the duct shielding assembly 620 components made of thermal insulation material to ensure that the duct plate 610 and the duct shielding assembly 620 have a certain degree of deformation. Of course, those skilled in the art may also, as needed, make the fan fixing component 652 and the airflow deflector 653 components made of thermal insulation material.

[0142] The insulation material can be plastic foam.

[0143] In simple terms, by making the duct plate 610 a component made of thermal insulation material, and / or by making the duct shielding assembly 620, the fan fixing component 652, and the airflow deflector 653 components made of thermal insulation material, the components between the top shell 640 and the bottom shell 630 can have a certain deformation in the thickness direction z. Based on this, the overall thickness of the components between the top shell 640 and the bottom shell 630 can be slightly larger without affecting the overall assembly of the partition assembly 600.

[0144] At the same time, the insulation material can also play a role in heat preservation, preventing the cold air in the variable temperature compartment 103 from being transferred to the cold storage compartment 102, thereby improving the heat preservation effect of the variable temperature compartment 103.

[0145] Go back and refer to Figure 5 In some embodiments of this utility model, the refrigerated inner liner 120 is provided with sliding grooves 121 extending in the front-back direction on both sides in the lateral direction for installing the partition assembly 600.

[0146] like Figure 19 and Figure 21 As shown, the partition assembly 600 is provided with a protruding rib 691 that slides with the slide groove 121, so that the partition assembly 600 can be installed into the refrigerator inner liner 120 in a push-pull manner.

[0147] like Figures 19 to 21As shown, in some embodiments of the present invention, the front end of at least one side of the partition assembly 600 in the lateral direction is provided with a stop structure 692, which abuts against the refrigerator inner liner 120 in the front-rear direction, thereby limiting the maximum deformation of the sealing member 660.

[0148] In addition, in other embodiments of this utility model, those skilled in the art can also use any other feasible method to fix the partition assembly 600 to the refrigerator inner liner 120 as needed, such as screw connection, snap-fit, etc.

[0149] Based on the foregoing description, those skilled in the art will understand that in this invention, the refrigerator 001 not only prevents the air in the variable temperature compartment 103 from flowing due to the pressure difference during heat preservation, but also prevents temperature cross-contamination between the variable temperature compartment 103 and the refrigerated compartment 102.

[0150] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.

[0151] Finally, it should be noted that the refrigerator 001 of this utility model is a refrigerator in a broad sense, which includes not only the refrigerator as commonly referred to in the narrow sense, but also preservation equipment with refrigeration and / or freezing functions, such as refrigerators, freezers, etc.

[0152] In this invention, the term "connection" means fluid communication, allowing fluid (e.g., air, liquid) to flow between two interconnected entities. Furthermore, this "connection" can be either a leak-free flow of fluid between two interconnected entities, or a flow with slight leakage of fluid between two interconnected entities.
