Since the evaporator chamber is connected to the freezer compartment, when the electric heating is turned on during the defrosting period of the storage device, while melting the frost on the evaporator, the hot air will enter the freezer compartment along the air return port and the air outlet of the air duct, causing the temperature to rise and resulting in temperature fluctuations, which affect the storage of food. Summary of the Utility Model

[0005] Specifically speaking, the freezer compartment is used to store items that need to be frozen, so as to keep the items fresh, such as food storage, medical sample preservation, and supplies for scientific research experiments, etc. The refrigeration chamber is used to evaporate and cool the air. The first air duct connects the freezer compartment and the refrigeration chamber, and can allow the air that has exchanged heat with the evaporator to flow from the refrigeration chamber into the freezer compartment via the first air duct. The second air duct connects the freezer compartment and the refrigeration chamber, and can promote the air in the freezer compartment to flow back to the refrigeration chamber via the second air duct, thereby ensuring the effectiveness of the air circulation in the freezer compartment and the refrigeration chamber and the uniformity of the temperature in the freezer compartment.
[0006] The evaporator is located in the refrigeration chamber and can absorb the heat of the refrigerant to evaporate it, thereby reducing the temperature of the air around the evaporator; the fan can drive the airflow to ensure that the air after heat exchange with the evaporator can enter the freezing chamber and return from the freezing chamber, providing power for the flow of air; the heating device is arranged in the refrigeration chamber and opposite to the evaporator, and can defrost the evaporator to ensure that the frost layer can be effectively removed when the evaporator is frosted; and the baffle group with a moving function can simultaneously close the first air duct and the second air duct, or simultaneously connect the first air duct and the second air duct, so that when the heating device defrosts the evaporator, it can be in a state of closing the first air duct and the second air duct to prevent hot air from entering the freezing chamber through the first air duct and the second air duct, and when the heating device does not need to defrost the evaporator and the storage device is in a normal refrigeration cycle, the baffle group simultaneously connects the first air duct and the second air duct, thereby realizing normal refrigeration air circulation in the freezing chamber and the refrigeration chamber. Among them, the movement of the baffle group between the first position and the second position can be driven by a driving component to provide a power source for movement, or can be manually operated.
[0007] According to the storage device of the present application, the first air duct and the second air duct can be closed and connected by changing the position of the partition group, so that the air can be circulated in the freezer compartment and the refrigeration chamber during the refrigeration cycle, and hot air can be prevented from entering the freezer compartment when the heating device defrosts the evaporator, thereby avoiding the possibility of the temperature in the freezer compartment rising and causing the items to thaw.
[0008] According to the storage device of the present application, the partition group includes at least one partition, and the partition is movable between a first position and a second position. The partition includes a first baffle portion and a second baffle portion connected to each other. When the partition is in the first position, the first baffle portion is opposite to the first air duct, and the second baffle portion is opposite to the second air duct. When the partition is in the second position, the first baffle portion avoids the first air duct, and the second baffle portion avoids the second air duct.
[0009] In detail, the partition group includes at least one partition, and the partition includes a first baffle portion and a second baffle portion that are connected to each other. When the partition is in a first position, the first baffle portion is opposite to the first air duct, thereby closing the first air duct, and the second baffle portion is opposite to the second air duct, thereby closing the second air duct. When the partition is in a second position, the first baffle portion avoids the first air duct, and the second baffle portion avoids the second air duct, thereby allowing air to flow in the first air duct and the second air duct without obstruction. The first baffle portion and the second baffle portion can be respectively provided with corresponding structures according to the positions and shapes of the first air duct and the second air duct, thereby realizing the closure or avoidance of the first air duct and the second air duct at different positions.
[0010] Optionally, the storage device further comprises: a driving assembly, wherein the driving assembly is drivingly connected to the partition plate group to drive the partition plate group to move between the first position and the second position.
[0011] According to the storage device of the present application, the driving component can use an electric motor, a cylinder or other suitable driving methods to achieve fast and stable driving of the partition group, thereby automatically adjusting the closure or conduction of the first air duct and the second air duct at the appropriate time when the storage device needs defrosting and after the defrosting is completed, thereby improving the user experience of the storage device.
[0012] Optionally, an installation cavity is defined between the freezing chamber and the refrigeration chamber, the partition is arranged in the installation cavity, a heat insulation sponge is sandwiched between the partition and a first side wall of the installation cavity, and the first side wall separates the freezing chamber and the installation cavity.
[0013] According to the storage device of the present application, the use of insulating sponge and the installation cavity can effectively block the heat transfer between the freezer compartment and the refrigeration chamber. At the same time, the installation cavity can facilitate the setting of the partition and the drive assembly to avoid affecting the space of the freezer compartment and affecting the position setting of various components in the refrigeration chamber, thereby minimizing the changes in the specification design of the storage device and reducing the manufacturing cost.
[0014] Optionally, a pressure piece is provided in the installation cavity, and the pressure piece is located on the side of the partition away from the insulation sponge. A wedge-shaped boss is provided on the partition, and the wedge-shaped boss has a wedge-shaped surface, and the wedge-shaped surface abuts against the pressure piece. The wedge-shaped surface is inclined in a direction gradually away from the first side wall in the direction from the first position to the second position.
[0015] According to the storage device of the present application, the pressure piece is located on the side of the partition away from the insulation sponge, and can be in direct contact with the wedge surface of the wedge-shaped boss, and the wedge surface has a specific inclination angle, so that in the process of the partition moving from the second position to the first position, the cooperation between the wedge surface and the pressure piece can adjust the gap between the partition and the first side wall, and the partition will gradually press the insulation sponge, thereby avoiding the existence of gaps and allowing hot air to escape when closing the first air duct and the second air duct. The cooperation between the wedge surface and the pressure piece can provide better mechanical support, facilitate the installation and disassembly of the partition, and can effectively transmit pressure and stress when the partition moves from the second position to the first position.
[0016] Optionally, a guide column is provided on one of the first side wall and the partition plate, and a guide groove is provided on the other one, and the guide column is clamped in the guide groove.
[0017] According to the storage device of the present application, since the partition needs to ensure that the first air duct and the second air duct can be accurately and completely closed during the movement, the position accuracy of the partition is required to be relatively high. By setting a guide column and a guide groove for coordination, during the movement of the partition, the guide column moves relative to the guide groove and is always in the guide groove.
[0018] Optionally, the first air duct defines an air outlet, the air outlet connects the freezer compartment and the refrigeration chamber, the axial direction of the air outlet is perpendicular to the first side wall, the first baffle portion is provided with a first avoidance opening, when the partition is in the first position, the first avoidance opening is staggered with the air outlet, when the partition is in the second position, the first avoidance opening is opposite to the air outlet, and the number of the air outlets and the first avoidance openings corresponds one to one.
[0019] According to the storage device of the present application, the axial direction of the air outlet is perpendicular to the first side wall, so the partition only needs to move along the direction in which the first side wall extends during the movement, so that the first avoidance port and the air outlet are staggered when the first baffle portion is in the first position, and the other solid areas of the first baffle portion shield the air outlet, thereby preventing the airflow from flowing into the freezer compartment through the air outlet; when the partition is in the second position, the first avoidance port and the air outlet are opposite to each other, so that the airflow can enter the freezer compartment through the first avoidance port and the air outlet.
[0020] Optionally, the second air duct defines an air return opening that communicates the freezing compartment and the refrigeration chamber. The axial direction of the air return opening is parallel to the first sidewall. The second baffle portion includes a first sub-baffle portion and a second sub-baffle portion that are connected to each other. The first sub-baffle portion is connected to the first baffle portion and perpendicular to the first sidewall. The second sub-baffle portion is connected to the first sub-baffle portion and parallel to the first sidewall. When the partition is in the first position, the first sub-baffle portion covers the air return opening, and the second sub-baffle portion is inserted into the air return opening. When the partition is in the second position, the first sub-baffle portion is spaced from the air return opening.
[0021] In the storage device according to the present application, setting the axial direction of the air return opening parallel to the first sidewall can enable the recirculated air to be evenly distributed in the refrigeration chamber, so that it is more convenient to be cooled by the evaporator, shortening the flow path of the recirculated air, thereby reducing the operating load of the evaporator and improving the refrigeration effect. At the same time, the uniform air flow can reduce the formation of frost on the evaporator, thereby extending the defrosting cycle. In order to enable the partition to simultaneously close the air outlet and the air return opening in different directions during linear movement, the first sub-baffle portion is set perpendicular to the first sidewall to facilitate closing the air return opening. In order to ensure that the first sub-baffle portion can accurately and completely close the air return opening, a second sub-baffle portion is provided. During the movement of the first sub-baffle portion towards the air return opening, the cooperation between the second sub-baffle portion and the air return opening is used to guide the first sub-baffle portion to ensure that when the second sub-baffle portion is completely inserted into the air return opening, the first sub-baffle portion can completely cover the air return opening. When the partition is in the second position, the second sub-baffle portion can be partially inserted into the air return opening or spaced from the air return opening.
[0022] Optionally, the first baffle portion includes a plurality of first sub-portions and a plurality of second sub-portions. Any two adjacent first sub-portions are connected by the second sub-portions. The first sub-portions are provided with the first avoidance openings, and the width of the second sub-portions is smaller than the width of the first sub-portions.
[0023] In the storage device according to the present application, setting the width of the second sub-portion smaller than the width of the first sub-portion can reduce the overall weight of the partition while not affecting the closing and avoidance of the first air duct and the second air duct, thereby reducing the load of the driving component. When a guiding groove is provided on the first baffle portion, the guiding groove is located on the second sub-portion, so that the positions of the guiding groove and the first avoidance opening can be reasonably arranged, effectively reducing the weight of the first baffle portion.
[0024] In the storage device according to the present application, the driving component specifically includes a driving portion, a gear, and a rack. The driving portion is in transmission connection with the gear, the rack is in transmission connection with the partition group, and the gear meshes with the rack.
[0025] According to the storage device of the present application, the meshing of a gear and a rack is utilized to achieve the transmission connection between the gear and the rack. The structures of the gear and the rack are firm and can bear a large load, that is, the weight of the partition. Moreover, the cooperation of the gear and the rack can achieve high-precision positioning control, which can enable the partition to accurately close the first air duct and the second air duct and accurately avoid the first air duct and the second air duct.

Detailed implementation manners
[0041] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0042] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0043] For ease of description, spatial relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation in addition to the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or change in motion state, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "over other elements or features". Therefore, the exemplary term "below" can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.
[0044] As Figures 1-4 shown, a storage device according to an embodiment of the present application includes a housing, and a freezing compartment 10, a first air duct 11, a second air duct 12, a refrigeration chamber 20, an evaporator 30, a blower 40, a heating device 50, and a partition group 60 are provided inside the housing.
[0045] Specifically, the first air duct 11 communicates with the freezing compartment 10 and the refrigeration chamber 20, and the second air duct 12 communicates with the freezing compartment 10 and the refrigeration chamber 20; the evaporator 30 is disposed in the refrigeration chamber 20; the blower 40 is disposed in the refrigeration chamber 20, and the blower 40 is configured to drive air to exchange heat with the evaporator 30 and then enter the freezing compartment 10 through the first air duct 11 and flow back into the refrigeration chamber 20 through the second air duct 12; the heating device 50 is disposed in the refrigeration chamber 20 and is opposite to the evaporator 30 to defrost the evaporator 30; the partition group 60 is movable and can simultaneously close the first air duct 11 and the second air duct 12 or simultaneously avoid the first air duct 11 and the second air duct 12.
[0046] Expanding on this, the freezing compartment 10 is used to store items that need to be frozen, so as to maintain the freshness of the items, such as supplies for food storage, medical sample preservation, and scientific research experiments, etc. The refrigeration chamber 20 is used to evaporate and cool air. The first air duct 11 communicates with the freezing compartment 10 and the refrigeration chamber 20, and can allow the air that has exchanged heat with the evaporator 30 to flow from the refrigeration chamber 20 into the freezing compartment 10 through the first air duct 11. The second air duct 12 communicates with the freezing compartment 10 and the refrigeration chamber 20, and can promote the air in the freezing compartment 10 to flow back into the refrigeration chamber 20 through the second air duct 12, thereby ensuring the effectiveness of the air circulation in the freezing compartment 10 and the refrigeration chamber 20 and the uniformity of the temperature in the freezing compartment 10.
[0047] The evaporator 30 is located within the refrigeration chamber 20 and can absorb the heat of the refrigerant to cause it to evaporate, thereby lowering the temperature of the air surrounding the evaporator 30.
[0048] The blower 40 is capable of driving the flow of air, ensuring that the air after heat exchange with the evaporator 30 can enter the freezing compartment 10 and flow back from the freezing compartment 10, providing power for the flow of air.
[0049] The heating device 50 is disposed within the refrigeration chamber and is disposed opposite to the evaporator 30, and can defrost the evaporator 30 to ensure that the frost layer can be effectively removed when the evaporator 30 is frosted.
[0050] The partition group 60 with a moving function can simultaneously close the first air duct 11 and the second air duct 12, or simultaneously conduct the first air duct 11 and the second air duct 12. Thus, when the heating device 50 defrosts the evaporator 30, the first air duct 11 and the second air duct 12 can be simultaneously closed to prevent hot air from entering the freezing compartment 10 through the first air duct 11 and the second air duct 12. When the heating device 50 does not need to defrost the evaporator 30 and the storage device is in a normal refrigeration cycle, the partition group 60 moves to conduct the first air duct 11 and the second air duct 12, thereby realizing the normal refrigeration air circulation within the freezing compartment 10 and the refrigeration chamber 20.
[0051] Among them, the movement of the partition group 60 between the first position and the second position can be provided with a power source for movement by driving the driving component 70. Among them, the driving component 70 can be electric or pneumatic, and of course, it can also be manually operated to move.
[0052] The partition group 60 can be made of materials resistant to low temperature and corrosion, such as stainless steel or plastic, to ensure stability in a low-temperature environment, and when in the first position, the partition group 60 should have good sealing performance.
[0053] In addition, the refrigeration chamber 20 and the freezing compartment 10 are usually located adjacent to each other within the storage device. For example, the refrigeration chamber 20 is generally located above the freezing compartment 10 or beside the freezing compartment 10. Some storage devices also have a refrigerating compartment, and the refrigerating compartment and the refrigeration chamber 20 are connected through a damper 90.
[0054] In addition, the extending modes of the first air duct 11 and the second air duct 12 include but are not limited to linear, curved or branched types, so as to adapt to different spatial layouts and requirements of the storage device.
[0055] The partition group 60 can be arranged in the freezing compartment 10, or can be arranged in the refrigeration chamber 20. Of course, it can also be independent of the freezing compartment 10 or outside the refrigeration chamber 20, as long as it can be on the extension paths of the first air duct 11 and the second air duct 12. For example, the partition group 60 includes two partitions 61, one partition 61 is arranged in the first air duct 11, and the other partition 61 is arranged in the second air duct 12, so as to realize the closing or conduction of the first air duct 11 and the second air duct 12.
[0056] According to the storage device of the embodiment of the present application, by changing the position of the partition group 60, the closing of the first air duct 11 and the second air duct 12 and the conduction of the first air duct 11 and the second air duct 12 can be realized. In this way, the circulation of air in the freezing compartment 10 and the refrigeration chamber 20 during the refrigeration cycle can be realized, and it can also be ensured that during the defrosting process of the evaporator 30 by the heating device 50, hot air will not enter the freezing compartment 10, thereby avoiding the possibility of the temperature in the freezing compartment 10 rising and causing the items to thaw.
[0057] In some embodiments, sensors can be configured at the position of the partition group 60, so as to better monitor whether the partition group 60 has moved in place.
[0058] As Figures 2-4 shown, in some embodiments, the partition group 60 includes at least one partition 61, the partition 61 is movable between a first position and a second position, the partition 61 includes a first baffle portion 62 and a second baffle portion 63 which are connected to each other. When the partition 61 is in the first position, the first baffle portion 62 faces the first air duct 11, and the second baffle portion 63 faces the second air duct 12. When the partition 61 is in the second position, the first baffle portion 62 avoids the first air duct 11, and the second baffle portion 63 avoids the second air duct 12.
[0059] Specifically, the partition group 60 includes at least one partition 61, the partition 61 includes a first baffle portion 62 and a second baffle portion 63 which are connected to each other. When the partition 61 is in the first position, the first baffle portion 62 faces the first air duct 11, so as to close the first air duct 11. As Figures 8-11 shown, the second baffle portion 63 faces the second air duct 12, so as to close the second air duct 12. When the partition 61 is in the second position, as Figures 5-7 shown, the first baffle portion 62 avoids the first air duct 11, and the second baffle portion 63 avoids the second air duct 12, so that the air flow in the first air duct 11 and the second air duct 12 is unobstructed. The first baffle portion 62 and the second baffle portion 63 can be respectively provided with corresponding structures according to the positions and shapes of the first air duct 11 and the second air duct 12, so as to realize the closing or avoidance of the first air duct 11 and the second air duct 12 at different positions.
[0060] It should be noted that the first position and the second position are only for the convenience of describing the relative position relationship between the partition plate group 60 and the first air duct 11 and the second air duct 12, and cannot be understood as a specific position. The specific position needs to be set according to the actual structure of the storage device.
[0061] The partition plate 61 may be configured to be in a flat plate shape, and a sealing strip structure may be provided at the edge thereof, thereby ensuring good sealing performance in the first position.
[0062] like Figure 3 As shown, the storage device according to the embodiment of the present application further includes a driving assembly 70, which is transmission-connected to the partition plate group 60 to drive the partition plate group 60 to move between the first position and the second position.
[0063] According to the storage device of the embodiment of the present application, the driving component 70 can use an electric motor, a cylinder or other suitable driving methods to achieve fast and stable driving of the partition group 60, thereby automatically adjusting the closure or conduction of the first air duct 11 and the second air duct 12 at the appropriate time when the storage device needs defrosting and after the defrosting is completed, thereby improving the user experience of the storage device.
[0064] like Figure 1 , Figure 2 , Figure 6 as well as Figure 9 As shown, in some embodiments, an installation cavity 80 is defined between the freezer compartment 10 and the refrigeration chamber 20, a partition 61 is disposed in the installation cavity 80, an insulating sponge 81 is sandwiched between the partition 61 and a first side wall 82 of the installation cavity 80, and the first side wall 82 separates the freezer compartment 10 and the installation cavity 80.
[0065] According to the storage device of the embodiment of the present application, the heat transfer between the freezer compartment 10 and the refrigeration chamber 20 can be effectively blocked by the heat insulation sponge 81 and the installation cavity 80. At the same time, the installation cavity 80 can facilitate the setting of the partition 61 and the drive assembly 70 to avoid affecting the space of the freezer compartment 10 and affecting the position setting of each component in the refrigeration chamber 20, thereby minimizing the changes in the specification design of the storage device and reducing the manufacturing cost.
[0066] like Figure 2 and Figure 10 As shown, in some embodiments, a pressing piece 83 is provided in the installation cavity 80, and the pressing piece 83 is located on the side of the partition 61 away from the insulation sponge 81. A wedge-shaped boss 611 is provided on the partition 61, and the wedge-shaped boss 611 has a wedge-shaped surface, which abuts against the pressing piece 83, and the wedge-shaped surface is inclined in a direction gradually away from the first side wall 82 in the direction from the first position to the second position.
[0067] The number of the pressing members 83 is one or more, and correspondingly, the number of the wedge-shaped bosses 611 is one or more. When the number of the wedge-shaped bosses 611 is multiple, the multiple wedge-shaped bosses 611 are sequentially spaced along the length direction of the partition 61 .
[0068] According to the storage device of the embodiment of the present application, the pressing piece 83 is located on the side of the partition 61 away from the thermal insulation sponge 81, and can be in direct contact with the wedge surface of the wedge-shaped boss 611, and the wedge surface has a specific inclination angle. In this way, in the process of the partition 61 moving from the second position to the first position, the cooperation between the wedge surface and the pressing piece 83 can adjust the gap between the partition 61 and the first side wall 82. The partition 61 will gradually press the thermal insulation sponge 81, so as to avoid the existence of gaps and the escape of hot air when the first air duct 11 and the second air duct 12 are closed. The cooperation between the wedge surface and the pressing piece 83 can provide better mechanical support, facilitate the installation and disassembly of the partition 61, and can effectively transmit pressure and stress when the partition 61 moves from the second position to the first position.
[0069] like Figure 4 , Figure 5 as well as Figure 8 As shown, in some embodiments, a guide column 821 is provided on one of the first side wall 82 and the partition plate 61 , and a guide groove 612 is provided on the other one, and the guide column 821 is clamped in the guide groove 612 .
[0070] In some embodiments, the first side wall 82 is provided with a guide post 821, and the number of the guide post 821 is one or more. In some embodiments, the partition 61 is provided with a guide groove 612, and the number of the guide groove 612 is one or more. The number of the guide posts 821 corresponds to the number of the guide groove 612, for example, two guide posts 821 correspond to one guide groove 612, and one guide post 821 corresponds to one guide groove 612. The guide post 821 is usually a long bar-shaped structure, and the shape of the guide post 821 can be cylindrical, square, hexagonal, etc. The shape of the guide groove 612 is usually matched with the shape of the guide post 821, so as to ensure matching with the shape of the guide post 821. For example, if the guide post 821 is cylindrical, the guide groove 612 may be semicircular, and if the guide post 821 is square, the guide groove 612 may also be a corresponding square. The depth and width of the guide groove 612 need to be large enough to accommodate the guide post 821 and allow it to move freely.
[0071] For the storage device according to the embodiments of the present application, since the partition 61 needs to ensure that the first air duct 11 and the second air duct 12 can be completely closed accurately during the movement process, therefore, the position accuracy requirements for the partition 61 are relatively high. By providing the cooperation of the guide posts 821 and the guide grooves 612, during the movement of the partition 61, the guide posts 821 move relative to the guide grooves 612 and are always located in the guide grooves 612.
[0072] As Figure 1 and Figure 6 shown, in some embodiments, the first air duct 11 defines an air outlet 111, the air outlet 111 communicates with the freezing compartment 10 and the refrigeration chamber 20, the axial direction of the air outlet 111 is perpendicular to the first side wall 82, the first baffle portion 62 is provided with a first avoidance opening 613. When the partition 61 is in the first position, the first avoidance opening 613 is staggered from the air outlet 111. When the partition 61 is in the second position, the first avoidance opening 613 and the air outlet 111 are opposite to each other, and the numbers of the air outlet 111 and the first avoidance opening 613 correspond one by one.
[0073] Specifically, since the axial direction of the air outlet 111 is perpendicular to the first side wall 82, during the movement of the partition 61, it only needs to move along the extending direction of the first side wall 82, so that when the first baffle portion 62 is in the first position, the first avoidance opening 613 and the air outlet 111 are staggered, and other solid areas of the first baffle portion 62 shield the air outlet 111, preventing the air flow from flowing into the freezing compartment 10 through the air outlet 111. When the partition 61 is in the second position, the first avoidance opening 613 and the air outlet 111 are opposite to each other, so that the air flow can enter the freezing compartment 10 through the first avoidance opening 613 and the air outlet 111.
[0074] It should be noted that the size of the first avoidance opening 613 needs to be at least slightly larger than the size of the air outlet 111.
[0075] Among them, the shape of the air outlet 111 includes but is not limited to being grille-shaped, circular or strip-shaped. In an embodiment of the present application, the shape of the air outlet 111 is strip-shaped, which can help the air to be more evenly distributed in the freezing compartment 10.
[0076] As Figure 1 、 Figure 7 and Figure 11As shown, in some embodiments, the second air duct 12 defines an air return opening 121. The air return opening 121 communicates with the freezing compartment 10 and the refrigeration chamber 20. The axial direction of the air return opening 121 is parallel to the first side wall 82. The second baffle portion 63 includes a first sub-baffle portion 631 and a second sub-baffle portion 632 that are connected to each other. The first sub-baffle portion 631 is connected to the first baffle portion 62 and perpendicular to the first side wall 82. The second sub-baffle portion 632 is connected to the first sub-baffle portion 631 and parallel to the first side wall 82. When the partition 61 is in the first position, the first sub-baffle portion 631 covers the air return opening 121, and the second sub-baffle portion 632 is inserted into the air return opening 121. When the partition 61 is in the second position, the first sub-baffle portion 631 is spaced from the air return opening 121.
[0077] Specifically, setting the axial direction of the air return opening 121 parallel to the first side wall 82 can enable the recirculated air to be evenly distributed in the refrigeration chamber, making it more convenient to be cooled by the evaporator 30, shortening the flow path of the recirculated air, thereby reducing the operating load of the evaporator 30 and improving the refrigeration effect. At the same time, the uniform air flow can reduce the formation of frost on the evaporator 30, thereby extending the defrosting cycle. In order to enable the partition 61 to simultaneously close the air outlet 111 and the air return opening 121 in different directions during linear movement, the first sub-baffle portion 631 is set perpendicular to the first side wall 82 to facilitate closing the air return opening 121. In order to ensure that the first sub-baffle portion 631 can accurately and completely close the air return opening 121, the second sub-baffle portion 632 is provided. During the movement of the first sub-baffle portion 631 towards the air return opening 121, the cooperation between the second sub-baffle portion 632 and the air return opening 121 is used to guide the first sub-baffle portion 631, ensuring that when the second sub-baffle portion 632 is completely inserted into the air return opening 121, the first sub-baffle portion 631 can completely cover the air return opening 121. When the partition 61 is in the second position, the second sub-baffle portion 632 can be partially inserted into the air return opening 121 or spaced from the air return opening 121.
[0078] In a specific embodiment, the air return opening 121 is located below the air outlet 111. A plurality of air outlets 111 are spaced apart in the height direction. The air return opening 121 is located below the air outlets 111 and is elongated. In some specific embodiments, air outlets 111 and air return openings 121 are provided on both sides of the blower 40. Correspondingly, partitions 61 are provided on both sides of the blower 40.
[0079] As Figure 11 shown, in some specific embodiments, the second air duct 12 presents a certain inclination angle and slopes upward in the direction from the freezing compartment 10 to the refrigeration chamber 20.
[0080] As Figure 2 and Figure 3As shown, in some embodiments, the first baffle portion 62 includes a plurality of first sub-portions 621 and a plurality of second sub-portions 622. Any two adjacent first sub-portions 621 are connected by a second sub-portion 622. A first avoidance opening 613 is provided on the first sub-portion 621, and the width of the second sub-portion 622 is less than the width of the first sub-portion 621.
[0081] For the storage device according to an embodiment of the present application, setting the width of the second sub-portion 622 to be less than the width of the first sub-portion 621 can reduce the overall weight of the partition 61 while not affecting the enclosure and avoidance of the first air duct 11 and the second air duct 12, thereby reducing the load of the driving component 70. When a guiding groove 612 is provided on the first baffle portion 62, the guiding groove 612 is located on the second sub-portion 622. In this way, the positions of the guiding groove 612 and the first avoidance opening 613 can be reasonably arranged, effectively reducing the weight of the first baffle portion 62.
[0082] As Figure 3 and Figure 4 As shown, for the storage device according to an embodiment of the present application, the driving component 70 specifically includes a driving portion 71, a gear 72, and a rack 73. The driving portion 71 is drivingly connected to the gear 72, the rack 73 is drivingly connected to the partition group 60, and the gear 72 meshes with the rack 73.
[0083] For the storage device according to an embodiment of the present application, by using the meshing of the gear 72 and the rack 73, the driving connection between the gear 72 and the rack 73 is realized. The structures of the gear 72 and the rack 73 are strong and can withstand a large load, that is, the weight of the partition 61. Moreover, the cooperation of the gear 72 and the rack 73 can achieve high-precision positioning control, which can enable the partition 61 to accurately enclose the first air duct 11 and the second air duct 12 and accurately avoid the first air duct 11 and the second air duct 12.
[0084] For the defrosting method according to an embodiment of the present application, which is used to control the above-mentioned storage device, the storage device includes a freezing compartment 10 and a refrigeration chamber 20. A first temperature sensor is provided in the freezing compartment 10, and a second temperature sensor is provided in the refrigeration chamber 20. The method includes:
[0085] Step S10: Detect the first operating temperature in the refrigeration chamber 20 in real time;
[0086] Step S20: When the first operating temperature meets the defrosting condition, control the partition group 60 to move from the second position to the first position to enter the defrosting mode.
[0087] According to the defrosting method of the present application, the first operating temperature in the refrigeration chamber 20 is detected in real time by the second temperature sensor. When the first operating temperature meets the defrosting condition, it indicates that there is more frost on the evaporator 30 and the refrigeration capacity decreases, and defrosting of the evaporator 30 is required. At this time, the partition group 60 is controlled to move from the second position to the first position, so that the first air duct 11 and the second air duct 12 change from the conducting state to the closed state, which is conducive to controlling the heating device 50 to defrost the evaporator 30. During the defrosting process, the fan 40 stops running, so as to ensure that during the defrosting process of the heating device 50 on the evaporator 30, hot air will not enter the freezing compartment 10, thereby avoiding the possibility of the temperature in the freezing compartment 10 rising and the items warming up and thawing.
[0088] The defrosting method according to the embodiment of the present application, when the first operating temperature meets the defrosting condition, specifically includes:
[0089] Step S21: Lower and adjust the refrigeration target temperature of the freezing compartment 10 from the first temperature to the second temperature;
[0090] Step S22: Detect the second operating temperature of the freezing compartment 10 in real time;
[0091] Step S23: When it is detected that the second operating temperature is less than or equal to the second temperature, control the partition group 60 to move from the second position to the first position and enter the defrosting mode;
[0092] Step S24: Detect the temperature of the refrigeration chamber 20 in real time. When it is detected that the temperature is greater than or equal to the first preset temperature, stop defrosting;
[0093] Step S26: Re-cool and detect the temperature of the refrigeration chamber 20. When it is detected that the temperature is less than or equal to the third preset temperature, control the partition group 60 to move from the first position to the second position, where the third preset temperature is less than the first preset temperature.
[0094] According to the defrosting method of the embodiment of the present application, during the defrosting process, since the refrigeration chamber 20 stops delivering cold air to the freezing compartment 10, the temperature of the freezing compartment 10 will rise. In order to delay the temperature rise of the freezing compartment 10 during defrosting, before defrosting, the freezing compartment 10 is pre-cooled first, and the refrigeration target temperature of the freezing compartment 10 is reduced from the first temperature to the second temperature. When it is detected that the second working temperature in the freezing compartment 10 is less than or equal to the second temperature, it is determined that the temperature in the freezing compartment 10 has met the pre-cooling requirement. At this time, the partition group 60 can be controlled to move from the second position to the first position to close the first air duct 11 and the second air duct 12, thereby entering the defrosting mode, that is, controlling the heating device 50 to turn on and controlling the fan 40 and the compressor to suspend operation; when it is detected that the temperature in the refrigeration chamber 20 is greater than or equal to the first preset temperature, it indicates that the temperature on the surface of the evaporator 30 has met the defrosting end requirement, and the defrosting is stopped, that is, controlling the heating device 50 to stop heating, controlling the compressor and the fan 40 to continue running for refrigeration, and detecting the temperature of the refrigeration chamber 20. When it is detected that the temperature is less than or equal to the third preset temperature, it indicates that the temperature in the refrigeration chamber 20 has met the refrigeration requirement for the freezing compartment 10. At this time, the partition group 60 can be controlled to move from the first position to the second position, so that the first air duct 11 and the second air duct 12 are re-conducted, which is conducive to the airflow entering the freezing compartment 10 through the first air duct 11 and flowing back from the freezing compartment 10 to the refrigeration chamber 20 through the second air duct 12. In this way, pre-cooling is carried out before defrosting, ensuring that the temperature of the freezing compartment 10 can meet the item storage conditions during defrosting. At the same time, after defrosting, it can ensure that the temperature in the refrigeration chamber 20 can realize refrigeration for the freezing compartment 10 before opening the first air duct 11 and the second air duct 12, ensuring that the defrosting process will not affect the freezing compartment 10.
[0095] In a specific embodiment, the second working temperature is 2 - 3 °C lower than the first working temperature.
[0096] In a specific embodiment, the third preset temperature is -16 °C to -22 °C, for example, -16 °C, -17 °C, -18 °C, -19 °C, -20 °C, -21 °C, and -22 °C, etc.
[0097] In some embodiments, the storage device further has a refrigerating compartment, and the refrigerating compartment and the refrigeration chamber 20 are connected through a damper 90. The defrosting method further includes:
[0098] Step S25, detecting the temperature of the refrigeration chamber 20. When it is detected that the temperature is less than or equal to the second preset temperature, the damper 90 is opened. The second preset temperature is less than the first preset temperature, and the second preset temperature is greater than the third preset temperature.
[0099] That is to say, when it is detected that the temperature of the refrigeration chamber 20 begins to decrease and is less than or equal to the second preset temperature, it indicates that the temperature in the refrigeration chamber 20 begins to decrease to meet the temperature requirement of the refrigerated compartment. Then, the air door 90 is opened to facilitate the delivery of cold air to the refrigerated compartment.
