Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a refrigeration appliance. Background Art

[0002] Nowadays, with the improvement of people's living standards, refrigeration appliances have entered thousands of households, such as refrigerators, wine cabinets and so on.

[0003] In order to make the compartment of the refrigeration appliance have a lower operating temperature, cooling gas, for example, cooled by an evaporator, can be supplied to the storage space of the compartment. For example, an air duct assembly can be provided at the rear wall of the compartment to guide the cooling gas to the air outlet so that the cooling gas is supplied to the storage space through the air outlet.

[0004] Typically, the air duct assembly occupies a large space in the compartment, which reduces the volume of the available storage space. In addition, the process of installing the air duct assembly in the compartment may be difficult to operate due to limited operating space, making it difficult to properly install the air duct assembly. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an improved refrigeration appliance to overcome at least one of the above-mentioned deficiencies in the prior art.

[0006] According to a first aspect of the present application, an embodiment of the present application provides a refrigeration appliance, which is provided with a compartment and an air duct located in the compartment. The air duct is provided with: an air duct inlet, through which cooling gas flows into the air duct; at least one air outlet, through which cooling gas in the air duct is supplied to the storage space of the compartment; and a main air duct located between the air duct inlet and the at least one air outlet. The main air duct has a first side and a second side extending in a height direction opposite to each other. The first side includes a slope section extending upwardly obliquely from the bottom of the air duct in a direction away from the second side. The air duct inlet is arranged at the second side and is opposite to the slope section of the first side.

[0007] The cooling gas entering the air duct can be guided by the slope section to flow upward. With the help of the slope section, the space occupied by the air duct can be reduced, especially the space occupied by the lower part of the air duct. The compartment can provide a larger storage space.

[0008] The ramp section can be formed in particular to extend straightly and obliquely upwards. By means of the ramp section extending straightly and obliquely upwards, the air duct can be significantly narrowed in the lower half.

[0009] According to an optional embodiment of the present application, the slope section intersects with the second side edge. This helps to reduce the space occupied by the air duct, especially the space occupied by the lower part of the air duct.

[0010] For example, the ramp section may extend over more than half of the width dimension and / or height dimension of the compartment. The angle at which the ramp section is tilted upward may in particular be more than 45°. The bottom end of the ramp section may be offset in the direction of the second side relative to the center of the compartment in the width direction. The top end of the ramp section may be offset upward relative to the center of the compartment. This configuration of the ramp section helps guide the cooling gas and reduces the space occupied by the lower part of the air duct. The air duct may be significantly narrowed at least in its lower half. Conversely, in the flow direction of the cooling gas, the air duct may gradually expand at least in its lower half so as to guide the cooling gas in an advantageous manner.

[0011] According to an optional embodiment of the present application, the air duct may be configured to guide the cooling gas to flow upward to the at least one air outlet. The at least one air outlet may include a plurality of air outlets and all of them are located above the slope section. This helps to achieve a desired uniform operating temperature in the second chamber.

[0012] According to an optional embodiment of the present application, the compartment may further include a return air vent, through which the air in the storage space returns to the evaporator chamber of the refrigeration appliance, and the return air vent is located below the slope section.

[0013] According to an optional embodiment of the present application, the inlet bottom wall of the air duct inlet may extend downwardly toward the main air duct and be connected to the bottom end of the slope section. The inlet bottom wall of the air duct inlet and the slope section form a substantially V-shaped structure. Condensed water that may occur may flow to the bottom of the V-shaped structure along the inlet bottom wall and the slope section.

[0014] According to an optional embodiment of the present application, a guide strip may be provided in the air duct inlet, the guide strip being located between an inlet top wall and an inlet bottom wall of the air duct inlet and extending parallel to the inlet bottom wall.

[0015] According to an optional embodiment of the present application, the refrigeration appliance may include: an air duct assembly for forming an air duct, the air duct assembly being provided with a receiving recess located below the slope section and on a side of the slope section away from the second side edge; and a fan or a storage box body located outside the air duct, the fan or the storage box body being at least partially located in the receiving recess. With the aid of the slope section, the air duct assembly can free up space below the slope section for arranging the fan or the storage box body, so that the storage space can have a larger volume.

[0016] According to an optional embodiment of the present application, the refrigeration appliance may include an air duct assembly for forming an air duct. The air duct assembly may include a first air duct portion for forming a first section of the air duct and a second air duct portion for forming a second section of the air duct located downstream of the first section. The first air duct portion and the second air duct portion are formed as separate components connected to each other. On the one hand, this helps to accurately install the air duct assembly in a convenient manner. On the other hand, the first air duct portion and the second air duct portion can be manufactured separately, which is conducive to forming the first section and the second section of the air duct in different ways.

[0017] According to an optional embodiment of the present application, the width dimension of the first air duct portion may be smaller than the width dimension of the second air duct portion. The smaller width dimension helps to align the first air duct portion with the air inlet of the compartment during installation and achieve a stable and reliable sealed connection.

[0018] According to an optional embodiment of the present application, a portion of the slope section may be formed in the first air duct portion, and another portion of the slope section may be formed in the second air duct portion. The slope section is particularly helpful in making the first air duct portion have a smaller width dimension.

[0019] According to an optional embodiment of the present application, the first air duct portion can be configured to be mounted to the compartment along the width direction, and the second air duct portion can be configured to be mounted to the compartment along a direction perpendicular to the width direction. This helps to achieve a stable and reliable sealed connection in an easy-to-operate manner.

[0020] According to an optional embodiment of the present application, the first air duct portion may be provided with a first joint surface facing the second air duct portion, and the second air duct portion may be provided with a second joint surface facing the first air duct portion. The first joint surface and the second joint surface may form a surface contact, so that the first section and the second section are connected in a sealed manner. With the help of the surface contact, the sealed connection between the first section and the second section can be achieved without additionally providing a seal between the first joint surface and the second joint surface.

[0021] According to an optional embodiment of the present application, the first joint surface and the second joint surface may be arranged to extend obliquely at least partially in a direction away from the storage space in a direction pointing from the first joint surface to the second joint surface. After the first air duct portion is installed in the compartment, the second air duct portion may be installed to the first air duct portion. The inclined first joint surface and the second joint surface may make the installation process more convenient and help ensure that the first section is sealedly connected to the second section.

[0022] According to an optional embodiment of the present application, a joint protrusion protruding toward the first joint surface may be provided at the second joint surface, and a joint concave portion for matching with the joint protrusion may be provided at the first joint surface, and the joint protrusion is embedded in the joint protrusion. Alternatively or additionally, a joint protrusion protruding toward the second joint surface is provided at the first joint surface, and a joint concave portion for matching with the joint protrusion is provided at the second joint surface, and the joint protrusion is embedded in the joint protrusion. The joint concave portion and the joint protrusion can effectively prevent cooling gas leakage.

[0023] For example, the joint protrusion and / or the joint recess may extend in a direction away from the storage space. The joint protrusion and / or the joint recess may in particular completely span the first joint surface and / or the second joint surface in the direction of their extension. This helps prevent leakage of cooling gas. Optionally, the width dimensions of the joint protrusion and the joint recess are narrowed in a direction away from the storage space. This helps to form a sealed connection and facilitates assembly.

[0024] According to an optional embodiment of the present application, the refrigeration appliance may include a temperature sensor, which is arranged on the air duct assembly adjacent to the first joint surface and / or the second joint surface. Relative to the joint between the first section and the second section of the air duct, the temperature sensor may be arranged on the same side as the joint protrusion and the joint recess and be located outside the joint protrusion and the joint recess. With the help of the joint protrusion and the joint recess, the accuracy of the temperature sensor can be effectively prevented from being reduced.

[0025] According to an optional embodiment of the present application, the storage space of the compartment may include a first storage space and a second storage space located below the first storage space. The second storage space can be set to have an operating temperature higher than the operating temperature of the first storage space. Thus, the functions of the refrigeration appliance can be more diversified.

[0026] According to an optional embodiment of the present application, the second storage space may be provided with a fan for sucking the cooling gas in the first storage space into the second storage space. The fan may be projected at least partially on the slope section in the width direction and in the height direction. The fan is arranged relative to the slope section in this way so that the largest possible storage space can be provided in the compartment without affecting the diversified functions of the compartment.

[0027] According to an optional embodiment of the present application, the compartment may be provided with a storage box body for separating the second storage space from the first storage space. The storage box body may be partially projected on the slope section in the width direction and in the height direction. This also helps to provide as large a storage space as possible in the compartment without affecting the diverse functions of the compartment.

[0028] According to an optional embodiment of the present application, the rear wall of the storage box body may have a first rear wall section close to the second side edge and a second rear wall section away from the second side edge. The first rear wall section may be offset forward relative to the second rear wall section to form a rear wall recess behind the first rear wall section. The air duct may be partially located at the rear wall recess, for example. Thus, the structure of the refrigeration appliance can be made more compact and a larger storage space can be provided.

[0029] The communication inlet for fluidly connecting the second storage space with the first storage space may be arranged at the second rear wall section. This facilitates accurate regulation of the temperature in the second storage space. Alternatively or additionally, a fan for sucking cooling gas in the first storage space into the second storage space may be arranged at the second rear wall section. In front of the fan and the first rear wall section, a regular space may be reserved for accommodating items to be cooled.

[0030] According to a second aspect of the present application, an embodiment of the present application provides a refrigeration appliance, which is provided with a compartment and an air duct assembly located in the compartment. The air duct assembly is configured to form an air duct for supplying cooling gas to a storage space of the compartment. The air duct assembly includes: a first air duct portion, which is used to form a first section of the air duct; and a second air duct portion, which is used to form a second section of the air duct located downstream of the first section. The first air duct portion is connected to the second air duct portion so that the first section is connected to the second section.

[0031] On the one hand, this helps to install the air duct assembly accurately in place in a convenient manner. On the other hand, the first air duct part and the second air duct part can be manufactured separately, which is conducive to forming the first section and the second section of the air duct in different ways.

[0032] According to an optional embodiment of the present application, the air duct assembly can be arranged between the compartment rear wall and the storage space of the compartment. The air inlet of the compartment can be arranged at the first side wall of the compartment. The first air duct portion can be connected to the first side wall so that the inlet of the first air duct portion is aligned with the air inlet. In this case, the first air duct portion and the second air duct portion can be installed to the compartment respectively, so that accurate installation can be achieved with a convenient installation operation.

[0033] According to an optional embodiment of the present application, the first air duct portion can be configured to be mounted to the compartment in the width direction so that the first air duct portion is connected to the first side wall. This helps to achieve a stable and reliable sealed connection in an easy-to-operate manner. For example, the first air duct portion can be inserted into the air inlet of the compartment in the width direction.

[0034] According to an optional embodiment of the present application, the second air duct portion can be configured to be installed in the compartment in a direction perpendicular to the width direction, so that the second air duct portion is connected to the first air duct portion. The second air duct portion can be installed in a convenient manner. For example, the second air duct portion can be configured to be installed in the compartment in a direction perpendicular to the rear wall of the compartment.

[0035] According to an optional embodiment of the present application, the width dimension of the first air duct portion may be smaller than the width dimension of the second air duct portion. The smaller width dimension helps to align the first air duct portion with the air inlet of the compartment during installation and achieve a stable and reliable sealed connection.

[0036] Optionally, the first duct portion may be connected to the first side wall and spaced apart from a second side wall opposite to the first side wall. During installation of the first duct portion, an operator may hold the first duct portion at a side of the first duct portion facing the second side wall for easy operation.

[0037] According to an optional embodiment of the present application, the inlet of the first air duct portion may form an air duct inlet of the air duct, and the cooling gas flows into the air duct through the air duct inlet. At least one air outlet of the air duct may be arranged in the second air duct portion, and the cooling gas in the air duct is supplied to the storage space of the compartment through the at least one air outlet.

[0038] According to an optional embodiment of the present application, the air duct may be provided with a main air duct located between the air duct inlet and the at least one air outlet. The main air duct may have a first side and a second side extending in the height direction opposite to each other. The first side may include a slope section extending upwardly obliquely from the bottom of the air duct in a direction away from the second side. The air duct inlet may be arranged at the second side and opposite to the slope section of the first side. Thus, the space occupied by the air duct can be reduced, in particular, the space occupied by the lower part of the air duct can be reduced. The cooling gas entering the air duct can be guided by the slope section to flow upward. The compartment can provide a storage space with a larger volume. The slope section can be formed in particular to extend upwardly obliquely in a straight line. With the aid of the slope section extending upwardly obliquely in a straight line, the air duct can be significantly narrowed in the lower half.

[0039] According to an optional embodiment of the present application, a portion of the slope section may be formed in the first air duct portion, and another portion of the slope section may be formed in the second air duct portion. The slope section is particularly helpful in making the first air duct portion have a smaller width dimension.

[0040] According to an optional embodiment of the present application, the slope section may intersect with the second side edge, which helps to reduce the space occupied by the air duct, and in particular, can reduce the space occupied by the first section of the air duct.

[0041] According to an optional embodiment of the present application, the first air duct portion may be provided with a first joint surface facing the second air duct portion, and the second air duct portion may be provided with a second joint surface facing the first air duct portion. The first joint surface and the second joint surface may form a surface contact, so that the first section and the second section are connected in a sealed manner. With the help of the surface contact, the sealed connection between the first section and the second section can be achieved without additionally providing a seal between the first joint surface and the second joint surface.

[0042] According to an optional embodiment of the present application, the first joint surface and the second joint surface may be arranged to extend obliquely at least partially in a direction away from the storage space in a direction pointing from the first joint surface to the second joint surface. After the first air duct portion is installed in the compartment, the second air duct portion may be installed to the first air duct portion. The inclined first joint surface and the second joint surface may make the installation process more convenient and help ensure that the first section is sealedly connected to the second section.

[0043] According to an optional embodiment of the present application, a joining protrusion protruding toward the second joining surface is provided at the first joining surface, and a joining recess for matching with the joining protrusion is provided at the second joining surface, and the joining protrusion is embedded in the joining protrusion.

[0044] Alternatively or additionally, a joint protrusion protruding toward the first joint surface is provided at the second joint surface, and a joint recess for matching with the joint protrusion is provided at the first joint surface, and the joint protrusion is embedded in the joint protrusion. The joint recess and the joint protrusion can effectively prevent cooling gas leakage.

[0045] For example, the joint protrusion and / or the joint recess may extend in a direction away from the storage space. The joint protrusion and / or the joint recess may in particular completely span the first joint surface and / or the second joint surface in the direction of their extension. This helps prevent leakage of cooling gas. Optionally, the width dimensions of the joint protrusion and the joint recess are narrowed in a direction away from the storage space. This helps to form a sealed connection and facilitates assembly.

[0046] According to an optional embodiment of the present application, the refrigeration appliance may include a temperature sensor, which may be arranged on the air duct assembly adjacent to the first joint surface. Relative to the joint between the first section and the second section of the air duct, the temperature sensor may be arranged on the same side as the joint protrusion and the joint recess and be located outside the joint protrusion and the joint recess. With the help of the joint protrusion and the joint recess, the accuracy of the temperature sensor can be effectively prevented from being reduced.

[0047] According to an optional embodiment of the present application, the first joint surface may include a first opening section, at least one first transverse section offset upward relative to the first opening section, and at least one first step section connected between the first opening section and the first transverse section. The second joint surface may include a second opening section, at least one second transverse section, and at least one second step section, respectively, which are opposite to the first opening section, the at least one first transverse section, and the at least one first step section. The main air duct may pass through the first opening section and the second opening section. The first step section and the second step section may extend upward. The first transverse section and the second transverse section may extend in the width direction. The first joint surface and the second joint surface extend laterally outward from the main air duct in a zigzag manner to prevent the cooling gas in the air duct from leaking to both sides via the leakage path extending in a straight line between the first joint surface and the second joint surface.

[0048] According to an optional embodiment of the present application, the storage space of the compartment may include a first storage space and a second storage space located below the first storage space. The second storage space can be set to have an operating temperature higher than the operating temperature of the first storage space. The second section of the air duct may be located above the first section of the air duct. The first section may be located directly behind the second storage space. The second section may be located directly behind the first storage space. The first air duct portion and the second air duct portion may form the first section and the second section of the air duct in different ways, thereby respectively adapting to the needs of the first storage space and the second storage space.

[0049] According to an optional embodiment of the present application, the first air duct portion can be configured so that the first section is circumferentially surrounded by a heat insulating material over its entire extension length, thereby helping to prevent condensation from occurring outside the cold first air duct portion and also helping to prevent the cooling gas from leaking directly from the first section to the storage space.

[0050] According to an optional embodiment of the present application, the second air duct portion may include a second heat insulating component made of a heat insulating material, and the second heat insulating component may enclose a second section of the air duct with the compartment rear wall of the compartment. This helps to reduce the depth dimension of the second air duct portion, so that the upper part of the storage space has a larger depth dimension.

[0051] According to an optional embodiment of the present application, the second air duct portion may include a second heat insulating component and a rear cover plate made of a heat insulating material. The second heat insulating component and the rear cover plate may enclose a second section of the air duct, and the rear cover plate and the second heat insulating component may be made of different materials. This also helps to reduce the depth dimension of the second air duct portion.

[0052] According to an optional embodiment of the present application, the air duct assembly may be provided with a receiving recess arranged side by side with the first air duct portion and located directly below the second air duct portion. The refrigeration appliance may also include a fan or a storage box body located outside the air duct, and the fan or the storage box body is at least partially located in the receiving recess. Thus, as large a storage space as possible can be provided in the compartment without affecting the diversified functions of the compartment. For example, the compartment may be provided with a storage box body for separating the second storage space from the first storage space. A portion of the storage box body may be projected onto the first air duct portion in the width direction and onto the second air duct portion in the height direction.

[0053] According to an optional embodiment of the present application, the rear wall of the storage box body may have a first rear wall section and a second rear wall section arranged in the width direction. The first rear wall section may be offset forward relative to the second rear wall section to form a rear wall recess behind the first rear wall section. The first air duct portion may, for example, be at least partially located at the rear wall recess. Thus, the structure of the refrigeration appliance can be made more compact and a larger storage space can be provided. The communication inlet for fluidly communicating the second storage space with the first storage space may be arranged at the second rear wall section. This is conducive to accurately regulating the temperature in the second storage space. Alternatively or additionally, a fan for sucking the cooling gas in the first storage space into the second storage space may be arranged at the second rear wall section. In front of the fan and the first rear wall section, a regular space can be reserved for accommodating items to be cooled.

[0054] According to an optional embodiment of the present application, at least a portion of the fan can be projected onto the first air duct portion in the width direction and onto the second air duct portion in the height direction. This is conducive to providing as much storage space as possible in the compartment without affecting the diverse functions of the compartment. BRIEF DESCRIPTION OF THE DRAWINGS

The main air duct has a first side and a second side extending in a height direction opposite to each other. The first side includes a slope section extending upwardly obliquely from the bottom of the air duct in a direction away from the second side. The air duct inlet is arranged at the second side and is opposite to the slope section of the first side.

[0125] On the other hand, an exemplary embodiment of the present application provides a refrigeration appliance, which is provided with a compartment and an air duct assembly located in the compartment. The air duct assembly is configured to form an air duct for supplying cooling gas to a storage space of the compartment. The air duct assembly includes: a first air duct portion, which is used to form a first section of the air duct; and a second air duct portion, which is used to form a second section of the air duct located downstream of the first section. The first air duct portion is connected to the second air duct portion so that the first section is connected to the second section.

[0126] In order to better understand the present application, exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0127] Before starting the detailed description, it should be pointed out that the directional terms used in the description process refer to the normal use state of the refrigeration appliance for the convenience of description and should not be understood as an absolute limitation on the corresponding features. In some drawings, arrows are schematically shown to indicate the height direction H, the width direction W and the depth direction D that are perpendicular to each other.

[0128] Figure 1 A refrigeration appliance according to an exemplary embodiment of the present application is schematically shown.

[0129] from Figure 1 As can be seen from the figure, the refrigeration appliance is provided with a compartment 1 and an air duct 2 located in the compartment 1. The compartment 1 can be used as a cold storage room, for example, and the items to be cooled can be stored in the storage space 10 of the compartment 1.

It should be understood by those skilled in the art that the above-mentioned compartment 1 can also be used as a freezer compartment, etc. The refrigeration appliance may include an air duct assembly 3 for forming an air duct 2 so as to supply cooling gas to the storage space 10 of the compartment 1. The air duct 2 may be at least partially formed in the air duct assembly 3. The air duct 2 may also be at least partially formed between the air duct component 3 and the wall of the compartment 1.

[0130] In this embodiment, the refrigeration appliance can be implemented as a combined refrigerator with a refrigerating chamber and a freezing chamber, for example. Those skilled in the art will understand that the present application is also applicable to other types of refrigerators, such as a separate refrigerator or freezer. In addition, as needed, the present application can also be applied to other refrigeration appliances other than refrigerators, such as a wine cabinet. The present application is particularly applicable to household refrigeration appliances.

[0131] Figure 2 The air duct assembly 3 of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown from the rear. Figure 1 and Figure 2It can be seen that the air duct 2 is provided with: an air duct inlet 21, through which cooling gas flows into the air duct 2; at least one air outlet 22, through which cooling gas in the air duct 2 is supplied to the storage space 10 of the compartment 1; and a main air duct 23 located between the air duct inlet 21 and the at least one air outlet 22. The main air duct 23 has a first side 231 and a second side 232 extending in the height direction H opposite to each other. The first side 231 includes a slope section 233 extending upwardly obliquely from the bottom of the air duct 2 in a direction away from the second side 232. The air duct inlet 21 is arranged at the second side 232 and opposite to the slope section 233 of the first side 231.

[0132] The cooling gas entering the air duct 2 can be guided by the slope section 233 to flow upward. With the help of the slope section 233, the space occupied by the air duct 2 can be reduced, especially the space occupied by the lower part of the air duct 2 can be reduced. The compartment 1 can provide a storage space 10 with a larger volume. With the help of the slope section 233, the air duct 2 can be significantly narrowed at a position opposite to the air duct inlet 21, which helps to reduce the difficulty of installation (which will be further described below).

[0133] The ramp section 233 can be formed to extend upwardly obliquely in a straight line in particular. It is also feasible that the ramp section 233 is formed to be slightly curved (with a smaller curvature). The present application can be distinguished from the following embodiments by the ramp section 233: the main branch has a bottom edge extending horizontally, and the bottom edge is connected to the first side 231 by a right angle or transitions to the first side 231 by a circular arc. By means of the ramp section 233 extending upwardly obliquely in a straight line, the air duct 2 can be significantly narrowed in the lower part. Conversely, in the flow direction of the cooling gas, the air duct 2 gradually expands in its lower part to guide the cooling gas in an advantageous manner.

[0134] The slope section 233 may intersect the second side 232 in particular. Therefore, there is no bottom extending horizontally between the slope section 233 and the second side 232. The main air duct 23 may have a substantially trapezoidal, particularly a right-angled trapezoidal cross section in a plane perpendicular to the depth direction D. The second side 232 forms the bottom of the trapezoid, and the slope section 233 forms the waist of the trapezoid. After entering the air duct 2, the cooling gas may be directly guided by the slope section 233 to flow upward. Thus, the space occupied by the air duct 2 may be reduced, in particular, the space occupied by the lower part of the air duct 2 may be reduced. The maximum width of the main air duct (the height of the trapezoidal cross section) may be formed to be close to the width of the compartment 1, for example, 70%, in particular, more than 80% of the width of the compartment 1.

[0135] The ramp section 233 may, for example, extend over more than half of the width dimension and / or height dimension of the compartment 1. The air duct 2 may be significantly narrowed at least in its lower half. Conversely, in the flow direction of the cooling gas, the air duct 2 may gradually expand at least in its lower half so as to guide the cooling gas in an advantageous manner. The angle at which the ramp section 233 is inclined upward may be, in particular, above 45°. The bottom end of the ramp section 233 is offset in the direction of the second side 232 relative to the center of the compartment 1 along the width direction W. For example, the bottom end of the ramp section 233 may be directly connected to the air inlet 14. For example, the top end of the ramp section 233 may be offset upward relative to the center of the compartment 1. The air outlet 22 may be arranged downstream of the ramp section 233, and therefore located above the ramp section 233. This configuration of the ramp section 233 helps guide the cooling gas and reduce the space occupied by the air duct 2. In particular, the space occupied by the lower part of the air duct 2 can be reduced.

[0136] See also Figure 1 , the refrigeration appliance may include, for example, an evaporator chamber 4 and an evaporator 5 arranged in the evaporator chamber 4. The gas cooled by the evaporator 5 may be guided to the storage space 10 of the compartment 1 to reduce the temperature. The evaporator chamber 4 may be located outside the compartment 1. For example, the evaporator chamber 4 may be arranged in another compartment. The refrigeration appliance may include a supply channel 6 for connecting the evaporator chamber 4 to the compartment 1 so as to supply the gas cooled by the evaporator 5 to the compartment 1 and a return channel 7 for guiding the gas in the storage space 10 of the compartment 1 to flow to the evaporator 5. The supply channel 6 may be connected to the air duct inlet 21.

[0137] exist Figure 2 The air duct inlet 21 is schematically shown by a dotted line. The air duct inlet 21 is arranged at the bottom end of the second side 232 of the main air duct 23. The inlet bottom wall 211 of the air duct inlet 21 can extend downwardly toward the main air duct 23 and be connected to the bottom end of the slope section 233. As a result, the inlet bottom wall 211 of the air duct inlet 21 and the slope section 233 form a roughly V-shaped structure. Condensed water that may appear can flow to the bottom of the V-shaped structure along the inlet bottom wall 211 and the slope section 233. Here, the condensed water can be discharged through the drainage structure. The condensed water can also be dried by the high-speed flowing and dry cooling gas flowing in from the air duct inlet 21. The V-shaped structure can collect the condensed water at its bottom. Even if condensed water or ice temporarily accumulates here, it will not affect the flow of the cooling gas or the normal operation of the compartment 1.

[0138] The air duct 2 may be configured to guide the cooling gas to flow upward to the at least one air outlet 22. The at least one air outlet 22 may include, for example, a plurality of air outlets 22 and all are located above the center of the compartment 1. This helps to achieve a desired uniform operating temperature in the compartment 1. Figure 2As shown, the at least one air outlet 22 may be provided at both sides and the top of the air duct assembly 3, for example. The at least one air outlet 22 may be arranged in a mirror-symmetrical manner. The slope section 233 described above helps to evenly supply cooling gas to the storage space from both sides, and prevents cooling gas from concentratedly flowing into the storage space from the side opposite to the air duct inlet 21.

[0139] The compartment 1 may further include a return air vent 15. The air in the storage space 10 may be returned to the evaporator chamber 4 of the refrigeration appliance through the return air vent 15. The return air vent 15 may be located below the slope section 233.

[0140] Figure 3 The compartment 1 and the air duct assembly 3 of the refrigeration appliance according to the present application are schematically shown. As an example, the compartment 1 can be used as a cold storage compartment of a refrigerator-freezer combination refrigerator with a single-cycle refrigeration circuit. The air duct assembly 3 for forming the air duct 2 can be arranged between the compartment rear wall 11 and the storage space 10 of the compartment 1. Here, the main air duct 23 is schematically shown with a dotted line. The compartment 1 may include a first side wall 12 and a second side wall 13 arranged opposite to each other. The air inlet 14 may be arranged at the first side wall 12 of the compartment 1. The air duct assembly 3 may be connected to the first side wall 12 so that the air duct inlet 21 is aligned with the air inlet 14. With the aid of the ramp section 233, the air duct 2 can be significantly narrowed at a position opposite to the air duct inlet 21. During the installation process, the above-mentioned narrowing helps to provide a larger operating space so as to ensure that the air duct inlet 21 is aligned with the air inlet 14 with high accuracy. Therefore, the ramp section 233 helps to reduce the difficulty of installation. The return air port 15 may be disposed at the rear wall 11 of the compartment 1 .

[0141] The air duct assembly 3 may be provided with a receiving recess 33 located below the slope section 233 and on a side of the slope section 233 away from the second side 232. For example, the fan 104 or the storage box body 103 located outside the air duct 2 may be at least partially located in the receiving recess 33 (to be further described below). With the aid of the slope section 233, the air duct assembly 3 can make room for the space below the slope section 233 for arranging the fan 104 or the storage box body 103, so that the storage space 10 can have a larger volume. Based on the conventional design idea of ​​flattening the appearance, the conventional air duct assembly faces the opening of the compartment with a flat front surface. The air duct assembly 3 is distinguished from such a conventional air duct assembly at least by the receiving recess 33.

[0142] According to an exemplary embodiment of the present application, the air duct assembly 3 may include a first air duct portion 31 for forming a first section 201 of the air duct 2 and a second air duct portion 32 for forming a second section 202 of the air duct 2 located downstream of the first section 201. The first air duct portion 31 and the second air duct portion 32 may be formed as separate components connected to each other. Figure 4A and Figure 4B The first air duct portion 31 and the second air duct portion 32 of the refrigeration appliance according to the exemplary embodiment of the present application are schematically shown respectively. The first air duct portion 31 can be connected to the second air duct portion 32 so that the first section 201 is connected to the second section 202.

[0143] On the one hand, this helps to accurately install the air duct assembly 3 in a convenient manner. On the other hand, the first air duct portion 31 and the second air duct portion 32 can be manufactured separately, which is conducive to forming the first section 201 and the second section 202 of the air duct 2 in different ways.

[0144] For example, during the assembly process, the second duct portion 32 may be installed in the compartment 1 after the first duct portion 31 is installed in the compartment 1. In particular, during the installation of the first duct portion 31, the available operating space is large, which can reduce the difficulty of operation and help ensure the accuracy of the installation position. When the duct assembly 3 has a large width, for example, the width of the duct assembly 3 is close to the width of the compartment 1, the first duct portion 31 and the second duct portion 32 as separate components are particularly conducive to reducing the difficulty of operation. The width dimension of the first duct portion 31 may be smaller than the width dimension of the second duct portion 32, which is conducive to the installation of the duct assembly 3. The width dimension of the second duct portion 32 may be close to the width dimension of the compartment 1, for example, it may be 80% or even more than 90% of the width dimension of the compartment 1.

[0145] Optionally, the first air duct portion 31 may be configured to be mounted to the compartment 1 along the width direction W. Here, "mounted along the width direction W" means that the mounting is achieved by means of relative displacement along the width direction W. For example, in combination with Figure 3 and Figure 4A and Figure 4B , the first air duct portion 31 can be connected to the first side wall 12 so that the inlet 311 of the first air duct portion 31 is aligned with the air inlet 14. The smaller width dimension of the first air duct portion 31 helps to align the first air duct portion 31 with the air inlet 14 of the compartment 1 in the compartment 1, and to achieve a stable and reliable sealed connection. In particular, the first air duct portion 31 can be connected to the first side wall 12 and spaced relative to the second side wall 13. During the installation of the first air duct portion 31, the operator can hold the first air duct portion 31 on the side of the first air duct portion 31 facing the second side wall 13 for easy operation. In an exemplary embodiment according to the present invention, the first air duct portion 31 can be engaged with the supply channel 6 at the air inlet 14. The connection between the inlet 311 of the first air duct portion 31 and the air inlet 14 and the optional supply channel 6 has a high requirement for sealing and is also difficult to operate.

[0146] Optionally, the first air duct portion 31 may be inserted into the air inlet 14 of the compartment 1 along the width direction W, which helps to form a sealed connection between the first air duct portion 31 and the air inlet 14, thereby preventing leakage of cooling gas.

[0147] The second air duct portion 32 can be configured to be installed to the compartment 1 in a direction perpendicular to the width direction W, so that the second air duct portion 32 is connected to the first air duct portion 31. For example, the second air duct portion 32 can be configured to be installed to the compartment 1 in a direction perpendicular to the compartment rear wall 11, that is, in the depth direction D, and connected to the first air duct portion 31. Alternatively or additionally, the second air duct portion 32 can be connected to the first air duct portion 31 downward in the height direction H.

[0148] The slope section 233 described above is particularly helpful to make the first air duct portion 31 have a smaller width dimension. Optionally, a portion of the slope section 233 may be formed in the first air duct portion 31, and another portion of the slope section 233 may be formed in the second air duct portion 32. In another embodiment, the air duct 2 may not have the above-mentioned slope section 233.

[0149] The advantages and possible improvements of the separate manufacturing of the first duct portion 31 and the second duct portion 32 are further described below. As described above, the first duct portion 31 and the second duct portion 32 can be manufactured separately, which is conducive to forming the first section 201 and the second section 202 of the air duct 2 in different ways. For example, the first duct portion 31 can be formed as a whole to be thicker than the second duct portion 32, so that the upper part of the storage space can have a larger depth dimension. Separate manufacturing in this case allows the first duct portion 31 and the second duct portion 32 to be formed under different manufacturing conditions. In general, the first duct portion 31 and the second duct portion 32 can be configured so that the thickness of the insulation material separating the first section 201 and the storage space is greater than the thickness of the insulation material separating the second section 202 and the storage space (see Figure 5 ).

[0150] Optionally, the first air duct portion 31 can be configured so that the first section 201 is surrounded by the heat insulating material along the circumferential direction over its entire extension length. This allows the first air duct portion 31 to have a better heat insulation effect and sealing effect. The first section 201 is located upstream, and the cooling gas in the first section 201 has a lower temperature. The first section 201 surrounded by the heat insulating material along the circumferential direction helps to prevent condensation from occurring on the outside of the cold first air duct portion 31, and also helps to prevent the cooling gas from leaking directly from the first section 201 to the storage space 10. In addition, the cooling gas can change direction in the first section 201, so better heat insulation effect and sealing effect are particularly advantageous. The second air duct portion 32 can be constructed differently from the first air duct portion 31, so that the second air duct portion 32 is not surrounded by the heat insulating material along the circumferential direction over at least part of the extension length, especially over most of the extension length. This helps to reduce the depth dimension of the second air duct portion 32, so that the upper part of the storage space 10 has a larger depth dimension.

[0151] exist Figure 4B 3 shows the front part of the first duct part 31 after the first duct part 31 is rotated at a certain angle. The inlet 311 of the first duct part 31 can form the duct inlet 21, so that the cooling gas can flow into the duct 2 through the inlet 311 of the first duct part 31. The inlet 311 of the first duct part 31 can be open in the width direction W and arranged to be aligned with the air inlet 14 of the compartment 1. The outlet 312 of the first duct part 31 can be open in the height direction H and connected to the inlet 321 of the second duct part 32 (refer to Figure 4A ). The cooling gas changes its flow direction in the first air duct portion 31. The at least one air outlet 22 of the air duct 2 may be disposed in the second air duct portion 32. In other words, the outlet 322 of the second air duct portion 32 may form the air outlet 22.

[0152] Figure 5 A cross-sectional view of an air duct assembly 3 of a refrigeration appliance according to an exemplary embodiment of the present application is schematically shown, wherein the cross-sectional position can be referred to as Figure 2 Section line AA is shown.

[0153] like Figure 5As shown, the first duct portion 31 can be configured so that the first section 201 is bounded by the heat insulating material in the front and rear. Although the lower part of the second duct portion 32 is locally formed to have a larger thickness so as to engage with the first duct portion 31, the second duct portion 32 can be formed as a whole to be significantly thinner than the first duct portion 31. The second duct portion 32 may, for example, include a second heat insulating component 325 and a rear cover plate 326 made of a heat insulating material, and the second heat insulating component 325 and the rear cover plate 326 surround the second section 202 of the duct 2. The rear cover plate 326 and the second heat insulating component 325 may be made of different materials. For example, the rear cover plate 326 may be formed as a plastic plate. This helps to reduce the depth dimension of the second duct portion 32, so that the upper part of the storage space 10 has a larger depth dimension.

[0154] Optionally, the second air duct portion 32 may include a second heat insulating member 325 made of a heat insulating material, and the second heat insulating member 325 may surround the second section 202 of the air duct 2 with the compartment rear wall 11 of the compartment 1. Thus, the depth dimension of the second air duct portion 32 may be reduced, so that the upper portion of the storage space 10 has a larger depth dimension.

[0155] Optionally, the air duct assembly 3 may further include a front cover plate 34. The front cover plate 34 may be arranged, for example, in front of the first air duct portion 31 and the second air duct portion 32. The front cover plate 34 may be assembled with the second air duct portion 32 and then installed in the compartment 1. The front cover plate 34 may also be a part of the second air duct portion 32 and be located in front of the second heat insulating component 325.

[0156] The first air duct portion 31 is connected to the second air duct portion 32, so that the first section 201 of the air duct 2 is connected to the downstream second section 202. Figure 4A , Figure 4B and Figure 5 It can be seen that the first air duct portion 31 may be provided with a first joint surface 313 facing the second air duct portion 32, and the second air duct portion 32 may be provided with a second joint surface 323 facing the first air duct portion 31. In the assembled state, the first joint surface 313 and the second joint surface 323 may form a surface contact, so that the first section 201 and the second section 202 are connected in a sealed manner. With the help of the above-mentioned surface contact, it is possible to achieve a sealed connection between the first section 201 and the second section 202 without additionally providing a seal between the first joint surface 313 and the second joint surface 323. This can not only simplify the structure of the air duct assembly 3, but also simplify the installation process of the air duct assembly 3. For example, it can avoid that the seal is displaced due to an erroneous installation operation, thereby reducing the sealing between the first section 201 and the second section 202.

[0157] The first joint surface 313 and the second joint surface 323 can be particularly arranged to extend at least partially in a direction away from the storage space 10 in a direction from the first joint surface 313 to the second joint surface 323. Figure 3 ), the first joint surface 313 and the second joint surface 323 can be arranged to extend upwardly obliquely in the backward direction. After the first air duct portion 31 is installed in the compartment 1, the second air duct portion 32 can be installed backward to the first air duct portion 31 along the depth direction D. By means of the installation action of installing the second air duct portion 32 backward to the first air duct portion 31, the second joint surface 323 is pressed backward on the first joint surface 313, so that the two form a close surface contact. The inclined first joint surface 313 and the second joint surface 323 can make the installation process more convenient and help ensure that the first section 201 is sealed and connected to the second section 202.

[0158] Alternatively, if Figure 4A and Figure 4B As shown, a joint protrusion 324 protruding toward the first joint surface 313 may be provided at the second joint surface 323, and a joint recess 314 for matching with the joint protrusion 324 may be provided at the first joint surface 313. The joint protrusion 324 may be embedded in the joint protrusion 324. The joint recess 314 and the joint protrusion 324 cooperate with each other so that the gap that may exist between the two meanders back and forth in a direction perpendicular to the width direction W. The cooling gas in the air duct 2 may leak to both sides along the width direction W through the gap between the first air duct portion 31 and the second air duct portion 32 that is difficult to completely avoid. The joint recess 314 and the joint protrusion 324 can effectively prevent the cooling gas from leaking. At the same time, the joint recess 314 and the joint protrusion 324 will not complicate the assembly operation of the first air duct portion 31 and the second air duct portion 32. On the contrary, the joint recess 314 and the joint protrusion 324 also contribute to the relative positioning of the first air duct portion 31 and the second air duct portion 32.

[0159] Alternatively or additionally, a joining protrusion 324 protruding toward the second joining surface 323 may be provided at the first joining surface 313 , and a joining recess 314 for cooperating with the joining protrusion 324 may be provided at the second joining surface 323 , wherein the joining protrusion 324 is embedded in the joining protrusion 324 .

[0160] For example, the engagement protrusion 324 and / or the engagement recess 314 may extend in a direction away from the storage space 10, for example, in the depth direction D. The engagement protrusion 324 and / or the engagement recess 314 may particularly completely span the first engagement surface 313 and / or the second engagement surface 323 in the direction of their extension. Figure 4B As shown, the engagement recess 314 may completely span the first engagement surface 313 in the depth direction D. This helps prevent cooling gas leakage.

[0161] Optionally, the width of the engaging protrusion 324 and the engaging recess 314 can be narrowed in the direction away from the storage space 10. Thus, in the process of installing the second air duct portion 32 backward to the second air duct portion 32, for example, in the depth direction D, the gap between the engaging protrusion 324 and the engaging recess 314 becomes smaller and smaller until they are completely fitted. This helps to form a sealed connection and facilitates assembly.

[0162] See also Figure 4A , the refrigeration appliance may include a temperature sensor 8. With the aid of the temperature sensor 8, the temperature in the compartment 1 can be detected. The temperature sensor 8 may be arranged on the air duct assembly 3 adjacent to the first joint surface 313 and / or the second joint surface 323. "The temperature sensor 8 is adjacent to the first joint surface 313 and / or the second joint surface 323" means that if the cooling gas in the air duct 2 leaks between the first joint surface 313 and the second joint surface 323, the leaked cooling gas will reduce the accuracy of the temperature sensor 8. With respect to the joint between the first section 201 and the second section 202 of the air duct 2, the temperature sensor 8 may be arranged on the same side as the joint protrusion 324 and the joint recess 314 and be located outside the joint protrusion 324 and the joint recess 314. With the aid of the joint protrusion 324 and the joint recess 314, the accuracy of the temperature sensor 8 can be effectively prevented from being reduced.

[0163] like Figure 4A and Figure 4B As shown, the first joint surface 313 may include a first opening section 3131, at least one first transverse section 3132 offset upward relative to the first opening section 3131, and at least one first step section 3133 connected between the first opening section 3131 and the first transverse section 3132. The second joint surface 323 may include a second opening section 3231, at least one second transverse section 3232, and at least one second step section 3233 that are respectively opposite to the first opening section 3131, the at least one first transverse section 3132, and the at least one first step section 3133. The main air duct 23 may pass through the first opening section 3131 and the second opening section 3231. The first step section 3133 and the second step section 3233 may extend upward. The first transverse section 3132 and the second transverse section 3232 may extend along the width direction W. The first joint surface 313 and the second joint surface 323 extend laterally outward from the main air duct 23 in a zigzag manner to prevent the cooling gas in the air duct 2 from leaking to both sides via the leakage path extending in a straight line between the first joint surface 313 and the second joint surface 323 .

[0164] Figure 6 A cross-sectional view of a first air duct portion 31 of a refrigeration appliance according to an exemplary embodiment of the present application is schematically shown.

[0165] The first air duct portion 31 may include a first body 315, which is formed with an air duct cavity 3151. The inlet 311 and the outlet 312 of the first air duct portion 31 may be connected to the air duct cavity 3151, so that the cooling gas can flow into the air duct cavity 3151 through the inlet 311 of the first air duct portion 31 and flow out of the first air duct portion 31 through the outlet 312 of the first air duct portion 31. The air duct cavity 3151 may be formed to have a triangular cross-section parallel to the main flow direction of the cooling gas in the air duct cavity 3151. The inlet 311 of the first air duct portion 31 and the outlet 312 of the first air duct portion 31 may be open in directions perpendicular to each other.

[0166] like Figure 6 As shown, a guide strip 213 may be provided in the air duct inlet 21, and the guide strip 213 is located between the inlet top wall 212 of the air duct inlet 21 and the inlet bottom wall 211 of the air duct inlet 21 and extends parallel to the inlet bottom wall 211. With the help of the guide strip 213, the cooling gas can be guided to flow into the main air duct 23 via the air duct inlet 21 along the desired flow direction.

[0167] The first duct portion 31 may further include a joint block 316 extending from a corner of the first body 315 in a direction away from the inlet 311 of the first duct portion 31 and in a direction toward the second section 202, and the joint block 316 is joined with the second duct portion 32. The joint recess 314 may be formed in the joint block 316.

[0168] Figure 7 A cross-sectional view of a refrigeration appliance according to an exemplary embodiment of the present application is schematically shown, wherein the cross-sectional position can be referred to as Figure 1 Section line BB is shown. Figure 8 A cross-sectional view of a compartment 1 of a refrigeration appliance according to an exemplary embodiment of the present application is schematically shown from a top view.

[0169] like Figure 7 As shown, the storage space 10 of the compartment 1 may include a first storage space 101 and a second storage space 102 located below the first storage space 101. The second storage space 102 may be set to have an operating temperature higher than the operating temperature of the first storage space 101. For example, a relatively independent first storage space 101 and second storage space 102 may be provided in the compartment 1 implemented as a refrigerating chamber, wherein the first storage space 101 may be implemented as a conventional refrigerating space, and the second storage space 102 may be implemented as a storage space dedicated to specific items. Thus, the functions of the refrigerating appliance may be more diversified.

[0170] Optionally, the second section 202 of the air duct 2 may be located above the first section 201 of the air duct 2, wherein the first section 201 is located directly behind the second storage space 102, and the second section 202 is located directly behind the first storage space 101. The first air duct portion 31 and the second air duct portion 32 may form the first section 201 and the second section 202 of the air duct 2 in different ways, so as to adapt to the needs of the first storage space 101 and the second storage space 102, respectively. For example, the first air duct portion 31 may be configured so that the first section 201 is surrounded by the heat insulation material along the circumference over its entire extension length, while the second air duct portion 32 may not be surrounded by the heat insulation material along the circumference over at least part of the extension length, especially over most of the extension length. The second section 202 may be surrounded by the second heat insulation component 325 and the compartment rear wall 11, for example. The temperature difference between the second storage space 102 with a higher temperature and the first section 201 located upstream is large. The first air duct portion 31 located directly behind the second storage space 102 can have better insulation and sealing effects. This helps to accurately control the temperature of the first storage space 101 and prevent condensation. The second air duct portion 32 located directly behind the second storage space 102 can be formed to be thinner than the second air duct portion 32, so that the first storage space 101 can have a larger volume, especially a larger depth dimension. The first storage space 101 is located above the second storage space 102 and is usually in a position that is more convenient for users to use. Therefore, making the first storage space 101 have a larger volume can improve the user experience. In addition, the cooling gas in the second section 202 can be directly supplied to the first storage space 101 via the air outlet 22. The temperature in the first storage space 101 is slightly different from the temperature in the second section 202, and the risk of condensation at the second air duct portion 32 is low.

[0171] See also Figure 1 and Figure 8, the second storage space 102 may be provided with a fan 104 for sucking the cooling gas in the first storage space 101 into the second storage space 102, for example. In an exemplary embodiment according to the present application, the air duct assembly 3 may be provided with a receiving recess 33 arranged side by side with the first air duct portion 31 and located directly below the second air duct portion 32. The fan 104 may be located outside the air duct 2 and at least partially in the receiving recess 33 of the air duct assembly 3. The fan 104 may be projected on the slope section 233 in particular at least partially along the width direction W and along the height direction H. The fan 104 is arranged in this way relative to the slope section 233 so that the largest possible storage space 10 can be provided in the compartment 1 without affecting the diversified functions of the compartment 1. This is also conducive to making the second storage space 102 have a regular receiving space for accommodating items to be cooled, thereby improving the user experience. Alternatively or additionally, at least a portion of the fan 104 is projected along the width direction W onto the first duct portion 31 and along the height direction H onto the second duct portion 32 .

[0172] The compartment 1 may be provided with a storage box 103 for separating the second storage space 102 from the first storage space 101. The storage box 103 may be partially projected on the slope section 233 along the width direction W and along the height direction H. Alternatively or additionally, a portion of the storage box 103 may be projected on the first air duct portion 31 along the width direction W and on the second air duct portion 32 along the height direction H. This also helps to provide as large a storage space 10 as possible in the compartment 1 without affecting the diverse functions of the compartment 1.

[0173] The storage box body 103 surrounds the second storage space 102 in a thermally insulating manner, for example, so that the second storage space 102 and the first storage space 101 can have independently settable temperatures. The storage box body 103 may include a thermally insulating wall made of a thermally insulating material, which surrounds the second storage space 102 in a thermally insulating manner. The storage box body 103 can be arranged in the compartment 1 in a detachable manner.

[0174] The at least one air outlet 22 of the air duct 2 may be arranged to be higher than the storage box body 103. This helps to achieve different operating temperatures of the first storage space 101 and the second storage space 102 in an energy-saving manner. The air duct 2 directly supplies cooling air to the first storage space 101 via the air outlet 22. The cooling air of the first storage space 101 may flow into the second storage space 102, for example, as needed, so as to adjust the temperature in the second storage space 102.

[0175] like Figure 8As shown, the storage box body 103 may be provided with a communication inlet 1031 and / or a communication outlet 1032 for fluidly connecting the second storage space 102 with the first storage space 101. The second storage space 102 may be connected to the first storage space 101 through the communication inlet 1031 and / or the communication outlet 1032, so that the second storage space 102 and the first storage space 101 are cooled by the cooling gas flowing out through the air outlet 22. The gas may enter the second storage space 102 from the first storage space 101 through the communication inlet 1031. The communication inlet 1031 and the at least one air outlet 22 may be staggered in the height direction H and the width direction W, so as to facilitate accurate adjustment of the temperature in the second storage space 102. The gas in the second storage space 102 may leave through the communication outlet 1032, and then may flow to the evaporator chamber 4 through the return channel 7.

[0176] The rear wall of the storage box body 103 has a first rear wall section 1033 close to the second side edge 232 and a second rear wall section 1034 away from the second side edge 232. The first rear wall section 1033 can be offset forward relative to the second rear wall section 1034 so as to form a rear wall recess 1035 behind the first rear wall section 1033. The air duct 2 can be partially located at the rear wall recess 1035. In particular, the first air duct portion 31 is at least partially located at the rear wall recess 1035. As a result, the structure of the refrigeration appliance can be made more compact and a larger storage space 10 can be provided. Combined with Figure 3 It can be seen that the second rear wall section 1034 can be located in the accommodating recess 33 below the slope section 233. With the aid of the slope section 233, the air duct assembly 3 and the storage box body 103 can be arranged more compactly.

[0177] The communication inlet 1031 can be arranged in particular at the second rear wall section 1034. This is conducive to accurately adjusting the temperature in the second storage space 102. Figure 3 and Figure 8 , the second rear wall section 1034 is located in the receiving recess 33 of the air duct assembly 3, so that the path of the cooling gas flowing from the first storage space 101 to the second storage space 102 is tortuous in the direction from top to bottom along the height direction H. Therefore, in the absence of a specific driving force, there may be almost no gas exchange or only a small amount of gas exchange between the first storage space 101 and the second storage space 102.

[0178] Alternatively or additionally, the fan 104 may be arranged at the second rear wall section 1034. In front of the fan 104 and the first rear wall section 1033, a regular space may be reserved for accommodating items to be cooled. For example, a container such as a drawer that can be withdrawn along the depth direction D may be arranged in front of the fan 104 and the first rear wall section 1033.

[0179] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the present disclosure, even when only a single embodiment is described with respect to specific features. The feature examples provided in the present disclosure are intended to be illustrative, not restrictive, unless otherwise stated. In specific implementations, multiple features may be combined with each other, depending on actual needs, where technically feasible. In particular, the features in different embodiments may also be combined with each other. Various replacements, changes, and modifications may also be conceived without departing from the spirit and scope of the present application.
