[0046] The present application provides a refrigeration device 10, which may be a refrigerator, a freezer, or the like.

[0047] Please refer to Figure 1 , Figure 1 The refrigeration device 10 includes a duct body 100 , a baffle assembly 200 , a second air duct body 300 , and a first air duct body 400 .

[0048] The partition assembly 200 includes a partition 210 installed within the container body 100, dividing the container body 100 into a first chamber 101 and a second chamber 102. By delivering different amounts of cooling to the first and second chambers 101, 102, the first and second chambers 101, 102 are exposed to different temperatures, creating distinct storage temperature zones within the same container body 100 and meeting the user's storage needs for different items. In one embodiment, the cooling temperature of the first chamber 101 is lower than that of the second chamber 102, allowing the first chamber 101 to function as a freezer while the second chamber 102 can function as a refrigerator or a temperature-controlled room.

[0049] In one embodiment, the partition 210 extends along the width direction of the gallbladder body 100 (ie Figure 1 The partition 210 divides the gallbladder body 100 into two parts along the height direction of the gallbladder body 100 (i.e. Figure 1 For the convenience of explanation, the chamber located below the partition 210 is defined as the first chamber 101, and the chamber located above the partition 210 is defined as the second chamber 102.

[0050] The second air duct body 300 is disposed in the first chamber 101, and the first air duct body 400 is disposed in the second chamber 102. Figure 2 , Figure 2 for Figure 1A partial cross-sectional view of the refrigeration device along section AA shows that the second air duct body 300 and the rear wall of the gallbladder body 100 define a heat exchanger chamber 1011. A first storage chamber 1012 is formed on the side of the second air duct body 300 facing away from the rear wall of the gallbladder body 100. The evaporator 500 is disposed in the heat exchanger chamber 1011. The second air duct body 300 can deliver the cold air in the heat exchanger chamber 1011 into the first storage chamber 1012, and the first air duct body 400 can be used to deliver the cold air into the second chamber 102.

[0051] In order to allow the cold air in the heat exchanger chamber 1011 to enter the second chamber 102, in the embodiment of the present invention, the partition 210 is provided with an air duct connecting the first chamber 101 and the second chamber 102, and the refrigeration device 10 can deliver and return cold air to the second chamber 102 through the air duct. Figure 2 And refer to Figure 3 , Figure 3 for Figure 1 A partial cross-sectional view of the refrigeration equipment along section BB shows that the air duct includes a supply air duct 210a and a return air duct 210b. The supply air duct 210a and the return air duct 210b are both connected to the first chamber 101 and the second chamber 102. The cold air in the heat exchanger chamber 1011 can be sent to the second chamber 102 through the supply air duct 210a to cool the second chamber 102. At the same time, the air after heat exchange in the second chamber 102 can be returned to the heat exchanger chamber 1011 through the return air duct 210b to achieve return air.

[0052] In the embodiment of the present invention, the air supply duct 210a and the return air duct 210b are provided on the partition 210, that is, the air supply duct 210a and the return air duct 210b are integrated into the partition 210. Compared with the traditional refrigerator in which pipes are pre-buried in the foam layer for air supply and return, there is no need to bury pipes in the foam layer, which reduces the thickness of the foam layer. Moreover, the air supply duct 210a and the return air duct 210b are provided by utilizing the space inside the partition 210, and will not occupy the internal space of the bladder body 100 extra, thereby increasing the storage space of the refrigeration device 10.

[0053] Please refer to Figure 4 , Figure 4 for Figure 1 sectional view of the refrigeration device along section CC. In the embodiment of the present application, the air supply duct 210a and the air return duct 210b are arranged along the width direction of the duct body 100.

[0054] By arranging the air supply duct 210a and the air return duct 210b along the width direction of the bladder body 100, that is, Figure 4The air supply duct 210a and the return air duct 210b are arranged in the horizontal direction (left-right direction) rather than along the front-to-back direction (depth direction) of the gallbladder body 100, so that the air supply duct 210a and the return air duct 210b can be located in the same row of space as much as possible. For example, the air supply duct 210a and the return air duct 210b are both arranged near the rear wall 110 of the gallbladder body 100, so that the air supply duct 210a and the return air duct 210b utilize the rear space of the second compartment 102 for air supply and return, so that the front and middle space of the second compartment 102 can be fully used for storing items, thereby improving the effective utilization rate of the space in the second compartment 102 and increasing the effective storage volume.

[0055] Please combine Figure 2 And refer to Figure 5 , Figure 5 The diagram below is a schematic diagram of the structure of a partition assembly according to an embodiment of the present invention. Partition assembly 200 also includes a damper 220, which is disposed in air duct 210a. Damper 220 is used to control the opening or closing of air duct 210a, thereby controlling the communication between first chamber 101 and second chamber 102. Specifically, when cooling second chamber 102 is required, damper 220 opens air duct 210a, allowing cool air to flow into second chamber 102 through air duct 210a. When cooling second chamber 102 is no longer required, damper 220 closes air duct 210a, preventing cool air from entering second chamber 102.

[0056] By setting the damper 220 in the air duct of the partition 210, that is, the damper 220 is integrated into the partition 210, compared with some refrigerators in the related art that bury the damper together with the air duct in the foam layer, the thickness of the foam layer is reduced, and the volume ratio of the storage space of the refrigeration equipment 10 can be further improved.

[0057] In the partition assembly 200 of the present invention, the partition 210 is provided with a supply air duct 210a, a return air duct 210b, and a damper 220. Specifically, the supply air duct 210a, the return air duct 210b, and the damper 220 are integrated into the partition 210. Compared to some refrigerators in the related art that embed the air ducts and dampers within the foam layer, the thickness of the foam layer is reduced. Furthermore, the supply air duct 210a, the return air duct 210b, and the damper 220 utilize the spatial arrangement of the partition 210 itself, without occupying additional space within the body 100, thereby increasing the storage space of the refrigeration device 10. Furthermore, by integrating the air duct and damper 220 into the partition 210, the integration of the partition assembly 200 is improved, and the number of components is reduced. The air duct and damper 220 can be installed into the body 100 together with the partition 210, reducing the number of assembly steps required to install separate components and improving the production efficiency of the refrigeration device 10.

[0058] In one embodiment, please refer to Figure 2 and Figure 3The second air duct body 300 is provided with a first air supply cavity 310 and a return air cavity 320, and the first air supply cavity 310 and the return air cavity 320 are arranged on the same side of the heat exchanger chamber 1011, wherein the first air supply cavity 310 is connected to the air supply duct 210a, and the return air cavity 320 is connected to the return air duct 210b.

[0059] As can be understood, the first air supply chamber 310 and the return air chamber 320 are both connected to the heat exchanger chamber 1011. The cold air in the heat exchanger chamber 1011 can be delivered to the second chamber 102 through the first air supply chamber 310 and the air supply duct 210a, thereby cooling the second chamber 102. The air in the second chamber 102 that has undergone heat exchange flows back into the heat exchanger chamber 1011 through the return air duct 210b and the return air chamber 320. Of course, the second air duct body 300 is provided with a first air supply port (not shown). The first air supply chamber 310 is connected to the first storage chamber 1012 through the first air supply port. The cold air in the heat exchanger chamber 1011 is delivered to the first storage chamber 1012 through the first air supply chamber 310 and the first air supply port.

[0060] Because the partition 210 is integrated with the return air duct 210b, in this embodiment, the second air duct body 300 is designed to cooperate with the partition 210. By providing the second air duct body 300 with a return air cavity 320, that is, the second air duct body 300 is integrated with the return air cavity 320, the air after heat exchange in the second chamber 102 is returned through the second air duct body 300. Compared with traditional refrigerators in which the return air cavity is buried in the foam layer, the thickness of the foam layer is reduced. Therefore, without changing the overall volume of the refrigeration device 10, the internal space of the refrigeration body 100 can be increased, thereby increasing the storage space.

[0061] Moreover, just as the above embodiment arranges the return air duct 210b and the supply air duct 210a along the width direction of the bladder body 100, this embodiment further arranges the first air supply chamber 310 and the return air chamber 320 in the width direction of the bladder body 100 by coordinating the positions of the first air supply chamber 310 and the return air chamber 320 with the return air duct 210b and the supply air duct 210a, so that the first air supply chamber 310 and the return air chamber 320 are also arranged along the width direction of the bladder body 100, so that the first air supply chamber 310 and the return air chamber 320 are both located on the same side of the heat exchanger chamber 1011, that is, the first air supply chamber 310 The return air chamber 320 and the return air chamber 320 are both located on the front side of the evaporator 500. Compared to some related art refrigerators that place the return air duct on the rear side (i.e., the back) of the evaporator, there is no need to reserve installation space on the rear side of the evaporator 500. In addition, the return air chamber 320 utilizes the internal space of the second air duct body 300. The arrangement of the return air chamber 320 does not require additional internal space of the bladder body 100. Therefore, the extra space created by the reduced thickness of the foam layer can be used for storage, thereby effectively increasing the storage space of the refrigeration device 10. In addition, compared to some related art refrigerators that place the return air duct on the left / right side of the evaporator, the return air chamber 320 does not require installation space of the evaporator 500, and there is no need to reduce the size of the evaporator 500, ensuring that the evaporator 500 has sufficient heat exchange area, thereby ensuring the cooling efficiency of the refrigeration device 10.

[0062] In one embodiment, if Figure 2 As shown, the first air duct body 400 is provided with a second air supply cavity 410 and a second air supply port (not shown) communicating with the second air supply cavity 410. The first air duct body 400 is communicated with the air supply duct 210a through the second air supply cavity 410. The cold air in the heat exchanger chamber 1011 is delivered into the second chamber 102 through the first air supply cavity 310, the air supply duct 210a, the second air supply cavity 410, and the second air supply port.

[0063] In one embodiment, please refer to Figure 4 The first air duct body 400 protrudes from the rear wall 110 of the gallbladder body 100 , and the return air duct 210 b is arranged on at least one side of the first air duct body 400 along the width direction of the gallbladder body 100 .

[0064] Along the width direction of the gallbladder body 100, that is, Figure 4In the left-right direction, the first air duct body 400 protrudes only from the middle portion of the rear wall 110 of the duct body 100, leaving space on the left and right sides of the first air duct body 400. In this embodiment, the return air duct 210b is disposed on at least one side of the first air duct body 400 along the width of the duct body 100, that is, the return air duct 210b is located on the left and / or right side of the first air duct body 400, thereby improving the utilization of the space within the second compartment 102. Furthermore, since the space above the partition 210 corresponding to the return air duct 210b is used for return air, the space above the return air duct 210b is unobstructed. By arranging the return air duct 210b on the left or right side of the first air duct body 400, this embodiment utilizes the vacant space on the left and right sides of the first air duct body 400 for return air, eliminating the need to occupy the storage space in front of the first air duct body 400. This allows the space in front of the first return air duct 210b to be fully used for storing items, thereby increasing the effective storage capacity of the second compartment 102.

[0065] In one embodiment, please refer to Figure 6 , Figure 6 This is a cross-sectional view of a partition assembly according to an embodiment of the present invention. Partition 210 includes an upper cover 211 and a lower cover 212. A first protrusion 2111 is provided on the side of upper cover 211 facing away from lower cover 212, and a second protrusion 2121 is provided on the side of lower cover 212 facing upper cover 211. Both first protrusion 2111 and second protrusion 2121 are constructed as cylindrical structures with open ends. The first protrusion 2111 and the second protrusion 2121 are joined to form the aforementioned air supply duct 210a. The bottom end of the first air duct body 400 is connected to the first protrusion 2111. Specifically, a first channel (not labeled) is formed within the first protrusion 2111, and a second channel (not labeled) is formed within the second protrusion 2121. The first and second channels are connected to form the air supply duct 210a.

[0066] In one embodiment, the damper 220 is disposed within the first passage of the first protrusion 2111. By forming the first protrusion 2111 by protruding from the upper cover 211 (resulting in a partially thickened partition 210), and disposing the damper 220 within the first protrusion 2111, the damper 220 utilizes the space formed by the upward protrusion of the upper cover 211 for installation. This eliminates the need to make the partition 210 as a whole very thick to accommodate the damper 220. Furthermore, the first protrusion 2111 is already used for connection to the first air duct body 400, and the upward protrusion of the first protrusion 2111 utilizes the space originally reserved for the installation of the first air duct body 400 (equivalent to reducing the height of the first air duct body 400 to leave space for the first protrusion 2111). Thus, the damper 220 does not occupy additional storage space in the second chamber 102. Therefore, this embodiment eliminates the need to thicken the partition 210 as a whole, effectively increasing the storage space.

[0067] In one embodiment, please refer to Figure 7 , Figure 7 This is a cross-sectional view of the assembly of the partition and the first air duct body of an embodiment of the present invention. One end of the first air duct body 400 is connected to the first protrusion 2111. A mating surface 420 is formed between the first air duct body 400 and the first protrusion 2111. The damper 220 is located on the side of the mating surface 420 facing away from the first air duct body 400.

[0068] By arranging the damper 220 on the side of the mating surface 420 facing away from the first air duct body 400, that is, the position of the damper 220 is lower than the position of the mating surface 420. Specifically, when the refrigeration device 10 cools only the first chamber 101, the damper 220 is in a closed state, and the cold air is blocked by the damper 220 in the air supply duct 210a of the partition 210. The cold air is located on the side of the mating surface 420 facing away from the first air duct body 400, and the cold air does not enter the first air duct body 400, and thus does not leak out from the mating surface 420. This effectively reduces the risk of cold air leaking from the connection between the partition 210 and the first air duct body 400 to the second chamber 102, prevents the temperature of the second chamber 102 from being affected, and prevents ice from forming.

[0069] In one embodiment, please refer again to Figure 6 The partition assembly 200 also includes a heat insulating member 230, which is installed in the first protrusion 2111. The heat insulating member 230 is provided with a receiving groove 231 and an air hole 232 connected to the receiving groove 231. The air door 220 is installed in the receiving groove 231, and the air door 220 is used to open or close the air hole 232.

[0070] By installing a thermal insulator 230 within the air supply duct 210a, the thermal insulator 230 cooperates with the damper 220 to isolate the high-temperature environment of the second chamber 102 from the low-temperature environment of the first chamber 101 (high-temperature and low-temperature environments are relative terms; both temperatures are lower than the temperature outside the refrigeration unit 10). This prevents the temperatures of the storage items in the first and second chambers 101, 102 from interfering with each other through the air supply duct 210a. Furthermore, by adaptively designing the thermal insulator 230, it is configured to block certain components of the damper 220, such as the electrical control components. This prevents cold air from directly hitting the electrical control components of the damper 220, prevents difficulty activating the damper 220 in extremely low temperatures, and ensures that the damper 220 opens and closes normally. The thermal insulator 230 can be made of materials such as foam, ensuring good airtightness between the damper 220 and the thermal insulator 230. When the damper 220 is closed, it effectively prevents cold air from entering the first air duct body 400.

[0071] In one embodiment, please refer to Figure 8 , Figure 8This is a cross-sectional view of the assembly of the thermal insulation member and the damper according to an embodiment of the present invention. The air hole 232 is constructed as a stepped hole. The air hole 232 includes a first through hole 2321 and a second through hole 2322 connected to the first through hole 2321. The second through hole 2322 is located on the side of the first through hole 2321 away from the second chamber 102.

[0072] The damper 220 includes an air duct 221, a mounting shell 222 and a baffle 223. The mounting shell 222 is connected to the outer wall of the air duct 221. The mounting shell 222 is installed in the accommodating groove 231. Part of the air duct 221 is arranged in the second through hole 2322 and is connected to the first through hole 2321. By designing the air hole 232 into the above shape, on the one hand, the damper 220 can better cooperate with the thermal insulation member 230. On the other hand, multiple turns are formed between the damper 220 and the inner wall of the thermal insulation member 230, which greatly increases the difficulty of cold air entering and effectively prevents cold air from leaking from the gap between the damper 220 and the thermal insulation member 230.

[0073] The baffle 223 is rotatably mounted on the mounting housing 222 and is located on a side of the air passage 221 away from the first through hole 2321. The baffle 223 is used to cover or expose the air passage 221. Specifically, when the baffle 223 covers the air passage 221, the damper 220 closes the air hole 232; when the baffle 223 exposes the air passage 221, the damper 220 opens the air hole 232.

[0074] By arranging the baffle 223 on the side of the air duct 221 away from the first through hole 2321, that is, the baffle 223 is located on the lower side of the air duct 221, when the baffle 223 covers the air duct 221, the cold air has an upward pushing effect on the baffle 223, so that the baffle 223 can tightly cover the air duct 221, avoiding the formation of a gap between the baffle 223 and the air duct 221, and preventing the cold air from leaking.

[0075] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of a gallbladder body according to an embodiment of the present invention. The gallbladder body 100 is provided with a mounting groove 130, which is recessed toward the outside of the gallbladder body 100. The mounting groove 130 may include a first groove portion recessed into the side wall 120 of the gallbladder body 100 and a second groove portion recessed into the rear wall 110 of the gallbladder body 100. The mounting groove 130 is generally U-shaped. The partition 210 can be inserted along the mounting groove 130 and fully snapped into the gallbladder body 100. The mounting groove 130 supports and positions the partition 210, allowing it to be quickly installed in the desired design position.

[0076] To prevent the partition 210 from sliding out of the mounting groove 130, please refer to Figure 4 and Figure 9A limiting portion 2113 is provided on one side of the partition 210 facing the side wall 120 of the gallbladder body 100 , and a second limiting groove 2114 is provided on the side wall 120 of the gallbladder body 100 , and the limiting portion 2113 is inserted into the first limiting groove.

[0077] The limiting portion 2113 is protruding from the side surface of the partition 210, located near the end of the partition 210 that is away from the rear wall 110 of the bladder body 100. The first limiting groove can be recessed into the bottom of the mounting groove 130. Because the limiting portion 2113 is protruding from the side surface of the partition 210, during installation, the limiting portion 2113 deforms and snaps into the first limiting groove. The first limiting groove limits the freedom of movement of the limiting portion 2113 along the front-to-back direction of the bladder body 100, thereby restricting the movement of the partition 210 and ensuring that the partition 210 is securely mounted in the mounting groove 130. This prevents the partition 210 from sliding out of the mounting groove 130 due to vibration or tilting.

[0078] To further ensure that the partition 210 is firmly installed in the installation groove 130, in one embodiment, please continue to refer to Figure 4 and Figure 9 , the partition 210 is provided with a buckle 2112 facing the rear wall 110 of the gallbladder body 100, and the partition 210 is snapped with the rear wall 110 of the gallbladder body 100 through the buckle 2112. Among them, the number of the buckles 2112 can be one or more, and this embodiment of the present application does not limit this. Specifically, the buckle 2112 is provided with a hook portion, and the rear wall 110 of the gallbladder body 100 is provided with a locking hole 140. When the partition 210 is fully inserted into the installation groove 130, the buckle 2112 is passed through the locking hole 140, so that the hook portion abuts against the outer surface of the rear wall 110 of the gallbladder body 100, so that the partition 210 is snapped and locked with the rear wall 110 of the gallbladder body 100 through the buckle 2112, which can ensure that the partition 210 is firmly connected to the gallbladder body 100.

[0079] As will be appreciated, since the cooling temperatures of the first chamber 101 and the second chamber 102 are different, an insulation layer (not shown) is provided within the partition 210 to prevent the temperatures of the first chamber 101 and the second chamber 102 from affecting each other. The insulation layer acts as a thermal insulator and can block heat transfer between the first chamber 101 and the second chamber 102. Specifically, the partition 210 includes an upper cover 211 and a lower cover 212. The upper cover 211 and the lower cover 212 are connected and enclose a thermal insulation cavity (not shown). The thermal insulation layer is provided within the thermal insulation cavity and can be formed by foaming a foaming liquid filled in the thermal insulation cavity.

[0080] In one embodiment, reference Figure 4As shown, the partition 210 is provided with a liquid injection port 210c on at least one side along its circumference, through which the foaming liquid can be injected into the heat preservation chamber. For example, a first liquid injection port can be provided on the side of the partition 210 facing the rear wall 110 of the bile body 100, and a second liquid injection port can be provided on the side of the partition 210 facing the side wall 120 of the bile body 100. The number of both the first liquid injection port and the second liquid injection port can be multiple.

[0081] A foam layer is provided on the outside of the bladder body 100. To improve the production efficiency of the refrigeration device 10, after the partition 210 is assembled to the bladder body 100, the insulation layer of the partition 210 and the foam layer on the outside of the bladder body 100 can be foamed together.

[0082] In one embodiment, if Figure 9 As shown, the bladder body 100 is provided with a through hole 160, the above-mentioned liquid injection port 210c of the partition 210 is connected to the through hole 160, and the thermal insulation layer is connected to the foaming layer as a whole through the liquid injection port 210c and the through hole 160. Specifically, during the production process of the refrigeration equipment 10, the partition 210 is first installed in the gallbladder body 100 so that the liquid injection port 210c of the partition 210 is connected to the through hole 160 of the gallbladder body 100, and then the refrigeration equipment 10 is foamed. During the foaming process, the foaming liquid injected into the outside of the gallbladder body 100 can flow into the interior of the partition 210 from the through hole 160 and the liquid injection port 210c. The foaming liquid in the partition 210 expands and solidifies to form the above-mentioned insulation layer. The insulation layer is connected to the foaming layer on the outside of the gallbladder body 100 through the liquid injection port 210c and the through hole 160 as a whole. The insulation layer and the foaming layer have a restraining effect on the partition 210, which can greatly enhance the firmness of the connection between the partition 210 and the gallbladder body 100.

[0083] Moreover, during the foaming process, the foaming liquid can penetrate between the partition 210 and the mounting groove 130 of the gallbladder body 100, and the foaming liquid can fill the gap between the partition 210 and the groove wall of the mounting groove 130, so that the partition 210 and the foaming layer separate the upper and lower first chambers 101 and the second chamber 102, thereby preventing cold leakage between the first chamber 101 and the second chamber 102.

[0084] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
