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, refrigeration appliances have entered thousands of households, such as refrigerators, wine cabinets, etc. People's demands for the functions of refrigeration appliances are becoming more and more diverse.

[0003] For example, refrigerators with multiple temperature zones are more popular with users. Refrigerators with multiple independent compartments are known. For example, a refrigerator may be provided with a refrigerating chamber, a freezing chamber, and a temperature-changing chamber. The independent compartments may be cooled by independent refrigeration systems, or be equipped with independent air ducts. Generally, the refrigeration circuit and air duct structure of such refrigerators are relatively complex, resulting in a significant increase in manufacturing costs. The refrigeration circuit of the refrigerator requires a considerable volume, which reduces the available storage space.

[0004] In addition, drawers can be arranged in the refrigerator compartment to separate multiple relatively independent storage areas. These storage areas usually have substantially the same or interrelated temperatures. In addition, separating multiple storage areas in the refrigerator compartment also faces problems such as high installation difficulty and small available drawer volume. Summary of the invention

[0005] An object of the embodiments of the present application is to provide an improved refrigeration appliance so as 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 having a storage space; an insulating shell, which is arranged in the compartment so as to separate a first storage space in the storage space so that the first storage space is separated from the remaining space in the storage space and can be cooled by gas from the remaining space, the insulating shell is provided with a connecting inlet for connecting the first storage space and the remaining space; and a first fan, which is configured to drive the gas in the remaining space to flow into the first storage space through the connecting inlet.

[0007] Thus, a method is provided for forming multiple temperature zones in a single compartment of a refrigeration appliance. The operating temperatures of the different temperature zones can be controlled independently and accurately. The first storage space is separated from the remaining space in the storage space in a heat-insulating manner on the one hand, and gas can be introduced from the remaining space by means of a first fan on the other hand. Thus, the first storage space can be cooled by gas from the remaining space and has an operating temperature independent of the remaining space.

[0008] According to an optional embodiment of the present application, the storage space may be provided with a rear wall surface that limits the storage space at the rear. The rear wall surface may be provided with a rear wall recess that is recessed backwards, and a part of the heat-insulating shell may be located in the rear wall recess. In this way, it is possible to provide as large a storage space as possible in the compartment, making the assembly process more convenient. In order to reduce the volume occupied by the first storage space, it is necessary to arrange the heat-insulating shell as close to the rear wall surface as possible. This will result in a very narrow gap between the heat-insulating shell and the rear wall surface. The narrow gap increases the difficulty of assembly. By utilizing the rear wall recess, a larger gap can be left between the heat-insulating shell and the rear wall surface while ensuring that the first storage space has a larger depth dimension.

[0009] According to an optional embodiment of the present application, the storage space may be provided with a rear wall surface that bounds the storage space at the rear. The rear wall surface may be provided with a rear wall recess that is recessed backwards, and the first fan may be at least partially located in the rear wall recess. This also helps to provide as large a storage space as possible in the compartment and makes the assembly process more convenient.

[0010] According to an optional embodiment of the present application, the heat-insulating housing may include a heat-insulating rear wall that limits the first storage space at the rear, and the connecting entrance may be arranged in the heat-insulating rear wall and located in the rear wall recess. In the absence of a rear wall recess, in order to increase the depth dimension of the first storage space, it is necessary to bring the heat-insulating rear wall of the heat-insulating housing as close to the rear wall surface as possible, resulting in a very narrow gap between the heat-insulating rear wall and the rear wall surface. There is a large obstacle for gas to enter the first storage space through the gap from the remaining space. In the case where the temperature of the first storage compartment needs to be lowered, in order to meet the temperature requirements of the first storage compartment, it is necessary to increase the flow rate of the introduced gas or reduce the temperature of the introduced gas. This usually leads to problems such as the required speed of the first fan becoming larger, or the required speed of the compressor of the refrigeration appliance becoming higher. These problems will increase the energy consumption required for the refrigeration appliance or increase the performance requirements of the refrigeration appliance. By locating the communication inlet in the recessed portion of the rear wall, a larger distance between the heat-insulating rear wall and the rear wall surface can be allowed while ensuring that the first storage space has a larger depth dimension, thereby leaving a larger gap for gas to flow through between the heat-insulating rear wall and the rear wall surface. Through this larger gap, the first fan can drive a larger flow of gas from the remaining space into the first storage space when it is started.

[0011] According to an optional embodiment of the present application, the heat-insulating housing may include a heat-insulating top wall that bounds the first storage space from above, and the remaining space may include a second storage space located above the heat-insulating top wall. The rear wall surface may include an upper adjacent area adjacent to the rear wall recess above the rear wall recess. The rear wall recess may include a recess bottom surface that is arranged offset backward relative to the upper adjacent area and a first recess side surface located above the recess bottom surface. The first recess side surface may extend forward from the recess bottom surface to the upper adjacent area. As a result, the gas flowing from the second storage space to the first storage space cannot flow from the second storage space to the connecting inlet along a straight path. This helps to reduce the natural convection between the first storage space and the second storage space when the first fan is turned off, and at the same time, when the first fan is turned on, the gas introduced into the first storage space from the second storage space via the channel can have a larger flow rate.

[0012] According to an optional embodiment of the present application, a channel for guiding gas to flow from the second storage space to the communicating inlet may be formed between the insulating shell and the rear wall surface. The channel may include a first channel portion located between the insulating top wall and the side of the first recess and a second channel portion located between the insulating rear wall of the insulating shell and the bottom surface of the recess. When the first fan is turned off, the natural convection between the first storage space and the second storage space can be reduced by using such a tortuous channel. The channel may have a larger flow cross-sectional area. When the first fan is turned on, gas can be introduced from the second storage space into the first storage space via the channel at a larger flow rate.

[0013] According to an optional embodiment of the present application, the distance between the surface area of ​​the heat-insulating top wall opposite to the side of the first recess and the side of the first recess may be smaller than the distance between the surface area of ​​the heat-insulating rear wall opposite to the bottom of the recess and the bottom of the recess. By setting such a differentiated distance, the natural convection between the first storage space and the second storage space can be reduced when the first fan is turned off, and a larger gap is left between the heat-insulating rear wall and the bottom of the recess. The larger gap between the heat-insulating rear wall and the bottom of the recess will not affect the natural convection between the first storage space and the second storage space, and can make the assembly process more convenient.

[0014] According to an optional embodiment of the present application, the heat-insulating top wall may be provided with a top wall recess that is sunken downward on its upper surface. The top wall recess may be opposite to the side wall of the first recess in the height direction, so that the gap between the side of the first recess and the heat-insulating housing is at least partially blocked in the front by the heat-insulating top wall. This can reduce the risk of foreign matter entering the channel. The user will hardly notice the existence of the rear wall recess from the front.

[0015] According to an optional embodiment of the present application, the rear wall surface may include a side adjacent region adjacent to the rear wall recess in the width direction. The rear wall recess may include a recess bottom surface arranged rearwardly offset relative to the side adjacent region and a second recess side surface arranged side by side with the recess bottom surface in the width direction. The second recess side surface may extend forward from the recess bottom surface to the side adjacent region.

[0016] Optionally, the insulated rear wall of the insulated housing, which delimits the first storage space at the rear, may include a first rear wall section and a second rear wall section arranged side by side in the width direction. The second rear wall section may be offset rearward relative to the first rear wall section. The second rear wall section may be at least partially located in the rear wall recess. The first rear wall section may be opposite to the side adjacent area of ​​the rear wall surface. The first fan may be arranged in particular at the second rear wall section. In front of the first fan and the first rear wall section, a regular space may be reserved for accommodating items to be cooled.

[0017] According to an optional embodiment of the present application, the storage space may be provided with a return air port so that the gas in the storage space can flow out through the return air port and flow to the evaporator chamber of the refrigeration appliance. The return air port may be located directly behind the first storage space. Optionally, the return air port is arranged to be staggered with the first fan in the width direction. Alternatively or additionally, the outer opening of the communication inlet is arranged staggered with the return air port in the width direction. The outer opening of the communication inlet may be arranged to be offset backward relative to the return air port, for example. There will be no direct fluid communication along a straight path between the return air port and the communication inlet. Alternatively or additionally, the first fan is arranged to be offset backward relative to the return air port. The return air port may be lower than the first fan in the height direction, and / or the return air port may be lower than the outer opening of the communication inlet in the height direction. The first fan is arranged to be offset backward relative to the return air port. The above-mentioned arrangement of the return air port helps to optimize the gas flow path in the storage space.

[0018] According to an optional embodiment of the present application, the refrigeration appliance may be provided with an inner liner for enclosing a compartment, and the rear wall surface of the storage space may be at least partially formed by the rear wall of the inner liner. Alternatively or additionally, the refrigeration appliance may be provided with an air duct cover plate, which is arranged in the compartment between the storage space and the air duct for supplying cooling gas into the storage space. The rear wall surface of the storage space may be at least partially formed by the air duct cover plate.

[0019] According to an optional embodiment of the present application, the air duct may extend from one side of the rear wall recess in the width direction to the top of the rear wall recess so as to bypass the rear wall recess. Thus, the air duct may leave space for arranging the first fan or the heat-insulating housing. The rear wall recess may have a larger size, thereby facilitating the realization of the various advantages of the rear wall recess described herein.

[0020] According to an optional embodiment of the present application, the air duct cover plate is provided with a first mounting structure, which is configured to allow a shielding cover for shielding the recessed portion of the rear wall to be detachably mounted to the air duct cover plate by means of the first mounting structure. The air duct cover plate can be applied to refrigeration appliances of various configurations, thereby reducing costs.

[0021] According to an optional embodiment of the present application, the refrigeration appliance may be provided with a first connector, which is attached to the heat-insulating housing through a wire and is configured to be electrically connected to a second connector arranged behind the air duct cover plate, so as to electrically connect the electrical device arranged in the heat-insulating housing to the second connector. The air duct cover plate may be provided with a cover plate opening at the rear wall recess, so that the first connector can be connected to the second connector through the cover plate opening. Thereby, while ensuring that the first storage space has a larger volume, the installation process can be made more convenient. In particular, using the rear wall recess and the cover plate opening, the first connector can be connected to the second connector in a manner that is easy to operate.

[0022] According to an optional embodiment of the present application, the refrigeration appliance may be provided with a first connector, which is attached to the heat-insulating housing by a wire and is configured to be electrically connected to a second connector arranged at the rear wall surface, so as to electrically connect the electrical device arranged in the heat-insulating housing to the second connector. The first connector and / or the second connector may be at least partially located in the rear wall recess. Thus, the installation process can be made more convenient while ensuring that the first storage space has a larger volume. Locating the first connector and the second connector in the rear wall recess can prevent the first connector and the second connector from occupying the volume of the storage space and will not hinder the gas flowing through the aforementioned channel.

[0023] According to an optional embodiment of the present application, the refrigeration appliance may be provided with an air duct located in the compartment, and the air duct is configured to supply cooling gas to the storage space through at least one air duct outlet. The at least one air duct outlet is particularly arranged above the heat-insulating shell. This helps to achieve the desired temperature in different temperature zones of the storage space. The air duct may include a first air duct section located directly behind the first storage space and a second air duct section located above the first storage space. The outer opening of the communication inlet may be arranged to be offset backward relative to any of the at least one air duct outlet.

[0024] According to an optional embodiment of the present application, the first air duct section does not have an air duct outlet for supplying cooling gas to the storage space. The first air duct section may be narrower than the second air duct section, for example, and at least a portion of the heat-insulating housing and / or at least a portion of the first fan and / or at least a portion of a connector for connecting the electrical device in the heat-insulating housing to a power supply outside the room are provided below the second air duct section and at a position transversely arranged with the first air duct section. The first air duct section and the first fan may be arranged side by side in the width direction.

[0025] According to an optional embodiment of the present application, the first fan may be arranged in the insulating shell and is suitable for being removed from the compartment along with the insulating shell. The communication inlet may be arranged in particular so that the gas exchange between the first storage space and the remaining space is suppressed when the first fan is not running. The insulating shell may be provided with a communication outlet for leading the gas from the first storage space to the remaining space, and the communication outlet and the communication inlet are both kept in a normally open state. In other words, the communication outlet and the communication inlet are always kept open, so that the first storage space and the remaining space are always connected by means of the communication outlet and the communication inlet. The refrigeration appliance may not be provided with a damper for controlling the open and closed state of the communication inlet. Thereby, the cost of the refrigeration appliance and the complexity of the operation method of the refrigeration appliance can be reduced.

[0026] According to an optional embodiment of the present application, the refrigeration appliance may be provided with an air duct assembly for forming an air duct, wherein the air duct is configured to supply cooling gas to the storage space. The air duct assembly may be provided with a receiving recess that is recessed in a direction away from the storage space. The first fan and / or the heat-insulating housing may be at least partially located in the receiving recess.

[0027] According to an optional embodiment of the present application, the refrigeration appliance may be provided with a heater for heating the first storage space. With the help of the heater, it is further helpful to provide multiple temperature zones in a single compartment of the refrigeration appliance, and the operating temperatures of different temperature zones can be independently and accurately controlled. In addition, the first storage space can also be multifunctional. For example, the first storage space may have a first storage mode, wherein the first storage mode has a first target temperature set independently of the temperature of the second storage space. The first target temperature is higher than the temperature of the second storage space. In order to achieve a higher first target temperature than the temperature of the second storage space, the heater can be turned on to increase the temperature in the first storage space. Thus, the first storage space and the second storage space can have different operating temperatures (especially operating temperatures with a large difference) and are suitable for storing different types of items. Optionally, the first storage space may have a second storage mode, wherein the settable temperature interval of the second storage mode may be lower than the settable temperature interval of the first storage mode. For example, in the second storage mode, the first storage space may have the same temperature as the second storage space. To this end, the heater can be turned off and the first fan can be turned on. The first storage space can be set to work in different storage modes to store different types of items. For example, the first storage space in the first storage mode is particularly suitable for storing tropical fruits or red wine, or for thawing frozen items; the first storage space in the second storage mode is particularly suitable for storing health products, medicines or skin care products.

[0028] In particular, the operating state of the heater can be arranged to be controllable according to the temperature of the first storage space and independently of the temperature of the remaining space.

[0029] The heater may be disposed, for example, in the heat-insulating bottom wall. When the heater is turned on, the hot air heated by the heater flows upward in the first storage space, thereby heating the first storage space uniformly. Therefore, when the heater is turned on, the first fan does not have to be turned on synchronously with the heater. Instead, the operating state of the first fan may be independent of the operating state of the heater. The heat-insulating housing may be disposed, for example, at the bottom of the storage space. This helps to make the temperature in the remaining space more uniform. The heater is disposed on the side opposite to the second storage space, thereby preventing the heater from affecting the temperature in the second storage space.

[0030] According to an optional embodiment of the present application, the working state of the first fan can be set to be controllable according to the temperature of the first storage space and independent of the temperature of the remaining space. Optionally, the refrigeration appliance may also be provided with a second fan for driving the cooling gas to flow into the storage space, and the working state of the second fan is set to be controllable according to the temperature of the remaining space and independent of the temperature of the first storage space.

[0031] 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 with a storage space; an air duct cover plate, which is arranged in the compartment between the storage space and the air duct for supplying cooling gas to the storage space, the air duct is at least partially located between the air duct cover plate and the first compartment wall of the compartment, the air duct cover plate is formed with a cover plate recess that is recessed in a direction away from the storage space, and the cover plate recess is isolated from the air duct; and a shielding cover, which is detachably mounted to the air duct cover plate to shield the cover plate recess. This can significantly reduce costs. Components such as air duct covers with the same configuration can be used in refrigeration appliances of different models. By removing or installing the shielding cover, the layout of the compartment of the refrigeration appliance can be flexibly adjusted, so that a heat-insulating housing can be set in the compartment to separate multiple temperature zones, and a reliable structure can also be provided without a heat-insulating housing.

[0032] For example, the air duct cover plate may include an adjacent area adjacent to the cover plate recess. The cover plate recess may include a recess bottom wall arranged offset in a direction away from the storage space relative to the adjacent area and a recess side wall extending from the recess bottom wall to the adjacent area. The adjacent area of ​​the air duct cover plate may, for example, form the upper adjacent area and / or the side adjacent area described above.

[0033] Optionally, the refrigeration appliance may include a container located in the storage space for accommodating items to be cooled, and the height of the shielding cover is not less than the height of the container. The container may, for example, be arranged at the bottom of the storage space instead of the heat-insulating housing.

[0034] According to an optional embodiment of the present application, the width dimension of the shielding cover may be greater than one third of the width dimension of the air duct cover plate and less than two thirds of the width dimension of the air duct cover plate.

[0035] According to an optional embodiment of the present application, the air duct cover plate may be provided with a return air port so that the gas in the storage space can flow out through the return air port and flow to the evaporator chamber of the refrigeration appliance, and the return air port and the shielding cover may be arranged side by side in the width direction.

[0036] According to an optional embodiment of the present application, the projections of the cover plate recess and the air duct in the depth direction do not overlap. In particular, the air duct may include a first air duct section arranged side by side with the cover plate recess in the width direction and a second air duct section located above the cover plate recess.

[0037] According to an optional embodiment of the present application, the air duct cover plate may be provided with a cover plate opening penetrating the air duct cover plate at the bottom wall of the recessed portion. The cover plate opening may be shielded by a shielding cover and will not be exposed to the storage space.

[0038] According to an optional embodiment of the present application, the shielding cover may include a shielding cover body. The shielding cover body may be arranged to be spaced apart from the bottom wall of the recess and between the bottom wall of the recess and the storage space. The shielding cover body may be arranged to be adjacent to and flush with the adjacent area. The shielding cover body may shield the cover plate recess in front. In particular, the shielding cover may form a flat rear wall surface of the storage space together with the air duct cover plate.

[0039] According to an optional embodiment of the present application, the shielding cover may further include a support column extending from the shielding cover body in a direction away from the storage space, and the support column abuts against the bottom wall of the recess. In this way, the shielding cover can be made more stable and reliable. Even if the shielding cover is pushed by cooling objects in the storage space or by a user during use, the shielding cover is not easily deformed or displaced.

[0040] According to an optional embodiment of the present application, the air duct cover plate may be provided with a first snap-fit ​​structure at the side wall of the recess. The shielding cover may be provided with a second snap-fit ​​structure extending from the shielding cover body in a direction away from the storage space. The first snap-fit ​​structure and the second snap-fit ​​structure may be arranged so that the shielding cover moves relative to the air duct cover plate in a direction perpendicular to the main plane of the air duct cover plate, and the second snap-fit ​​structure can form a snap-fit ​​fit with the first snap-fit ​​structure. The shielding cover can be installed in a simple manner without the need for additional installation components or tools. In a refrigeration appliance without the shielding cover installed, the function of the air duct cover plate will not be adversely affected.

[0041] According to an optional embodiment of the present application, the shielding cover may further include a first flange extending from an edge of the shielding cover body adjacent to the second compartment wall in a direction away from the first compartment wall, wherein the first flange is connected to the second compartment wall of the compartment adjacent to the first compartment wall. Through the first flange, the shielding cover can be installed in place more stably and foreign matter can be prevented from entering the rear of the shielding cover.

[0042] According to an optional embodiment of the present application, the second compartment wall may be provided with a locking groove. The first flange may be provided with a locking protrusion protruding toward the second compartment wall on a side facing the second compartment wall. The locking protrusion can be embedded in the locking groove to connect the first flange to the second compartment wall. The first flange can be fixedly connected to the second compartment wall by means of the locking protrusion in a manner that is easy to install.

[0043] According to an optional embodiment of the present application, the air duct cover plate is provided with a second flange extending in a direction away from the first compartment wall at its edge adjacent to the second compartment wall, the second flange extending between the first flange and the second compartment wall and provided with a through hole, and the locking protrusion passes through the through hole and is embedded in the locking groove. The first flange serves to fix the second flange to the second compartment wall. Thus, the shielding cover, the air duct cover plate and the second compartment wall can be fixed together in a manner that is easy to install. This connection method is particularly helpful in preventing foreign matter from entering the gap between the shielding cover and the air duct cover plate and between the air duct cover plate and the first compartment wall from the storage space.

[0124] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the scope of protection of the present application.

[0125] First, for ease of understanding, let's go back to the description in the background technology section. The refrigeration appliances in the prior art have the problems of complex structure, high cost, small available storage space, and great difficulty in installation.

[0126] In response to at least one of the above-mentioned technical problems or other possible technical problems, an exemplary embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment with a storage space; an insulating shell, which is arranged in the compartment so as to separate a first storage space in the storage space so that the first storage space is separated from the remaining space in the storage space and can be cooled by gas from the remaining space, the insulating shell is provided with a connecting inlet for connecting the first storage space and the remaining space; and a first fan, which is configured to drive the gas in the remaining space to flow into the first storage space through the connecting inlet.

[0127] In response to at least one of the above technical problems or other possible technical problems, another exemplary embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment with a storage space; an air duct cover plate, which is arranged in the compartment between the storage space and an air duct for supplying cooling gas to the storage space, the air duct is at least partially located between the air duct cover plate and a first compartment wall of the compartment, the air duct cover plate is formed with a cover plate recess that is recessed in a direction away from the storage space, and the cover plate recess is isolated from the air duct; and a shielding cover, which is detachably mounted to the air duct cover plate so as to shield the cover plate recess.

[0128] In order to better understand the present application, exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0129] 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, the height direction H, the width direction W and the depth direction D, which are perpendicular to each other, are schematically shown by arrows.

[0130] Figure 1 A refrigeration appliance according to an exemplary embodiment of the present application is schematically shown.

[0131] from Figure 1 As can be seen in the figure, the refrigeration appliance is provided with a compartment 1, which has a storage space 10. The items to be cooled can be stored in the storage space 10 of the compartment 1. The compartment 1 can be used as a cold storage room, for example. The storage space 10 can have an access opening that is open to the front. The refrigeration appliance is provided with a door (not shown here) for closing the access opening. The storage space 10 can be closed by a single cold storage door. When the door is open, the access opening is open, and the user can take and put items through the access opening.

[0132] from Figure 1It can also be seen that the refrigeration appliance may include a plurality of compartments 1 formed in the housing of the refrigeration appliance. For example, in addition to the compartment 1 used as a refrigerating chamber, the refrigerating appliance may also include, for example, a freezing chamber located to the left of the refrigerating chamber and a temperature-changing chamber or an ice chamber located below the refrigerating chamber. The housing of the refrigerating appliance separates the compartments 1. Those skilled in the art will appreciate that the compartments 1 may also be used as a freezing chamber, etc.

[0133] The refrigeration appliance is further provided with an insulating housing 2 and a first fan 3. The insulating housing 2 is arranged in the compartment 1 so as to separate a first storage space 101 in the storage space 10 so that the first storage space 101 is separated from the remaining space in the storage space 10 and can be cooled by gas from the remaining space. The insulating housing 2 is provided with a communication inlet 21 for connecting the first storage space 101 and the remaining space (see Figure 3 The first fan 3 is configured to drive the gas in the remaining space to flow into the first storage space 101 through the communication inlet 21. The remaining space refers to the space in the storage space 10 other than the first storage space 101.

[0134] On the one hand, the first storage space 101 is separated from the remaining space in the storage space 10 in a heat-insulating manner by means of the heat-insulating shell 2, and on the other hand, gas can be introduced from the remaining space by means of the first fan 3. Therefore, the first storage space 101 can be cooled by the gas from the remaining space and has an operating temperature independent of the remaining space. Thus, a method for forming multiple temperature zones in a single compartment 1 of a refrigeration appliance is provided. The operating temperatures of different temperature zones can be independently and accurately controlled. The temperature in the first storage space 101 can have a large temperature difference with the temperature in the remaining space. In the case of a change in the temperature in the remaining space, the temperature in the first storage space 101 can remain unchanged. The temperature in the remaining space can also remain unchanged in the case of a change in the temperature in the first storage space 101.

[0135] The insulating housing 2 may include an insulating layer made of an insulating material, such as insulating foam.

[0136] In this embodiment, the refrigeration appliance can be implemented as a combined refrigerator with a refrigerating chamber and a freezing chamber. 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.

[0137] Figure 2 The compartment 1 and the heat-insulating housing 2 of the refrigeration appliance according to the exemplary embodiment of the present application are schematically shown in an exploded view.

[0138] like Figure 2 As shown, the compartment 1 can be surrounded by the inner liner 4 of the refrigeration appliance. The storage space 10 of the compartment 1 can be provided with a rear wall surface 11 that limits the storage space 10 at the rear. The rear wall surface 11 can be formed, for example, partially or completely by the rear wall of the inner liner 4. The rear wall surface 11 can be provided with a rear wall recess 111 that is recessed backward. The insulating housing 2 for separating the first storage space 101 is arranged in the compartment 1 in a particularly detachable manner. The insulating housing 2 can be arranged so that a part of the insulating housing 2 is located in the rear wall recess 111. As a result, it is possible to provide as large a storage space 10 as possible in the compartment 1 and make the assembly process more convenient (which will be described in more detail below).

[0139] The heat-insulating housing 2 may, for example, completely surround the first storage space 101 in all directions. The heat-insulating housing 2 may include: a heat-insulating top wall located above the first storage space 101, a heat-insulating bottom wall opposite to the heat-insulating top wall, a heat-insulating rear wall located behind the first storage space 101, a heat-insulating front wall opposite to the heat-insulating rear wall, and heat-insulating side walls located on both sides of the first storage space 101.

[0140] Optionally, the heat-insulating housing 2 and the compartment wall of the compartment 1 may surround the first storage space 101. For example, the heat-insulating housing 2 may include a heat-insulating top wall and a heat-insulating rear wall, and the first storage space 101 is bounded by the compartment wall at the bottom and on both sides.

[0141] Figure 3 The compartment 1 of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown in a cross-sectional view, wherein the cross-sectional position can be referred to as Figure 1 Section line AA is shown.

[0142] The refrigeration appliance may be provided with an inner liner 4 for enclosing a compartment 1 and an air duct assembly 5 for forming an air duct 50. The air duct assembly 5 may be arranged in the compartment 1, for example, at the rear wall of the inner liner 4. The air duct 50 may be configured to supply cooling gas to the storage space 10.

[0143] The air duct assembly 5 may be provided with an air duct cover plate 51, which is arranged in the compartment 1 between the storage space 10 and the air duct 50 for supplying cooling air into the storage space 10. The rear wall surface 11 of the storage space 10 may be at least partially formed by the air duct cover plate 51. Optionally, the rear wall surface 11 is formed by the rear wall of the liner 4 and the air duct cover plate 51.

[0144] like Figure 3As shown, the heat-insulating housing 2 may be arranged, for example, at the bottom of the storage space 10. The heat-insulating housing 2 may include at least a heat-insulating top wall 23 that delimits the first storage space 101 at the top. The remaining space includes a second storage space 102 located above the first storage space 101. In the height direction H, the heat-insulating top wall 23 is located between the first storage space 101 and the second storage space 102 and separates the two.

[0145] Alternatively, it is also feasible that the second storage space 102 is located below the first storage space 101. In another embodiment, the second storage space 102 of the other space may also be arranged side by side with the first storage space 101 along the width direction W.

[0146] As described above, the first storage space 101 can be cooled by the gas from the remaining space. The first storage space 101 is not directly connected to the air duct 50. Instead, the cooling gas in the air duct 50 can be directly supplied to the second storage space 102, and can flow from the second storage space 102 into the first storage space 101 as needed.

[0147] The second storage space 102 can be used as a cold storage space, for example, and can have an operating temperature of 2° C. to 8° C. The first storage space 101 can have an operating temperature independent of the second storage space 102. For example, the first storage space 101 can be configured to have a higher operating temperature than the second storage space 102. The heat-insulating housing 2 allows the first storage space 101 to have an operating temperature that is significantly different from that of the second storage space 102.

[0148] exist Figure 3 In the illustrated embodiment, the refrigeration appliance is further provided with a heater 91 for heating the first storage space 101. With the aid of the heater 91, it is further helpful to provide multiple temperature zones in a single compartment 1 of the refrigeration appliance, and the working temperatures of different temperature zones can be independently and accurately controlled. In addition, the first storage space 101 can also be multifunctional.

[0149] For example, the first storage space 101 may have a first storage mode, wherein the first storage mode has a first target temperature that is set independently of the temperature of the second storage space 102. The first target temperature is higher than the temperature of the second storage space 102. For example, the first target temperature may be between 8°C and 12°C. In order to achieve a first target temperature that is higher than the temperature of the second storage space 102, the heater 91 may be turned on to increase the temperature in the first storage space 101. Thus, the first storage space 101 and the second storage space 102 may have different operating temperatures and be suitable for storing different kinds of items.

[0150] Optionally, the first storage space 101 may have a second storage mode, wherein the settable temperature interval of the second storage mode may be lower than the settable temperature interval of the first storage mode. For example, in the second storage mode, the first storage space 101 may have the same temperature as the second storage space 102. To this end, the heater 91 may be turned off and the first fan 3 may be turned on.

[0151] The first storage space 101 can be set to work in different storage modes to store different types of items. For example, the first storage space 101 in the first storage mode is particularly suitable for storing tropical fruits or red wine, or for thawing frozen items; the first storage space 101 in the second storage mode is particularly suitable for storing health products, medicines or skin care products.

[0152] It is particularly advantageous that the first storage space 101 having the first storage mode is arranged at the bottom of the storage space 10. In the first storage mode, the first storage space 101 may have a higher temperature than the second storage space 102 located above it. Since the density of hot air is smaller and the density of cold air is larger, the first storage space 101 being located at the bottom is conducive to making the temperature distribution of the second storage space 102 more uniform. On the contrary, the upper and lower temperature differences in the second storage space 102 may be aggravated. In the case of switching from the first storage mode to the second storage mode, the first storage space 101 being located at the bottom of the storage space 10 helps to shorten the time to complete the mode switching. By introducing cooling gas from the bottom of the second storage space 102, the first storage space 101 can be cooled to the desired temperature more quickly.

[0153] The insulating shell 2 may include an insulating bottom wall 24 that bounds the first storage space 101 at the bottom. The heater 91 may be particularly disposed in the insulating bottom wall 24. When the heater 91 is turned on, the hot air heated by the heater 91 flows upward in the first storage space 101, so that the first storage space 101 is evenly heated. Therefore, when the heater 91 is turned on, the first fan 3 does not have to be turned on synchronously with the heater 91. Instead, the operating state of the first fan 3 may be independent of the operating state of the heater 91. In addition, the heater 91 is arranged on the side opposite to the second storage space 102, so that the heater 91 is prevented from affecting the temperature in the second storage space 102.

[0154] The first fan 3 may be arranged in particular in the heat-insulating housing 2 and may be removed from the compartment 1 along with the heat-insulating housing 2. For example, the heat-insulating housing 2 may include a heat-insulating rear wall 22 that delimits the first storage space 101 at the rear, and the first fan 3 may be mounted to the heat-insulating rear wall 22. When the first fan 3 is turned on, it may draw gas in the second storage space 102 into the first storage space 101.

[0155] The working state of the first fan 3 can be set to be controllable according to the temperature of the first storage space 101 and independent of the temperature of the remaining spaces. The working state of the first fan 3 can be set to be turned off, run at a specific working power, or run at a specific on-off ratio.

[0156] For example, see Figure 1 The refrigeration appliance may be provided with a first temperature sensor 92 for detecting the temperature of the first storage space 101 and / or a second temperature sensor 93 for detecting the temperature of the remaining space. The working state of the first fan 3 may be adjusted according to the detection result of the first temperature sensor 92, for example.

[0157] Alternatively or additionally, the operating state of the heater 91 may be configured to be controllable according to the temperature of the first storage space 101 and independent of the temperature of the remaining spaces.

[0158] For example, when the first storage space 101 is in the first storage mode, when the actual temperature of the first storage space 101 is lower than the first target temperature of the first storage space 101, the heater 91 can be operated, and when the actual temperature of the first storage space 101 is higher than the first target temperature of the first storage space 101, the heater 91 can be turned off.

[0159] Optionally, when the first storage space 101 is in the first storage mode, the first fan 3 operates with a lower on / off ratio or lower power so as to reduce the gas exchange between the first storage space 101 and the remaining spaces and prevent condensation.

[0160] When the first storage space 101 is in the second storage mode, the heater 91 may remain off, and the first fan 3 may be operated with a higher on / off ratio or higher power.

[0161] Optionally, the refrigeration appliance is further provided with a second fan 94 for driving cooling gas to flow into the storage space 10. The working state of the second fan 94 can be set to be controllable according to the temperature of the remaining space and independent of the temperature of the first storage space 101.

[0162] For example, the refrigeration appliance may include an evaporator chamber 95 and an evaporator 96 arranged in the evaporator chamber 95. The gas cooled by the evaporator 96 may be guided to the storage space 10 of the compartment 1 to reduce the temperature. The evaporator chamber 95 may be located outside the compartment 1. For example, the evaporator chamber 95 may be arranged in a freezer outside the compartment 1. The refrigeration appliance may include a supply channel 97 for connecting the evaporator chamber 95 to the compartment 1 so that the gas cooled by the evaporator 96 is supplied to the compartment 1 and a return channel 98 for guiding the gas in the storage space 10 to flow to the evaporator 96. The second fan 94 may drive the cooling gas from the evaporator chamber 95 to enter the air duct 50 of the compartment 1 via the supply channel 97, and flow into the storage space 10 through the air duct 50.

[0163] When the second temperature sensor 93 detects that the temperature in the second storage space 102 is too high, for example, the second fan 94 may be started or the working efficiency of the second fan 94 may be increased, so that more cooling gas is supplied to the storage space 10. Thus, the temperature of the second storage space 102 may be lowered without directly affecting the first storage space 101.

[0164] Back to Figure 3 The rear wall surface 11 of the storage space 10 may be provided with a rear wall recess 111 that is recessed backward. A portion of the heat-insulating housing 2 may be located in the rear wall recess 111. Alternatively or additionally, the first fan 3 may be at least partially located in the rear wall recess 111. This helps to provide as large a storage space 10 as possible in the compartment 1 and facilitates the assembly process.

[0165] See also Figure 3 , it can be imagined that in the absence of the above-mentioned rear wall recess 111, the first fan 3 arranged at the heat-insulating rear wall 22 needs to be arranged closer to the opening, and the depth dimension and volume of the first storage space 101 will be reduced. In order to reduce the occupation of the volume of the first storage space 101, it is necessary to arrange the first fan 3 and / or the heat-insulating shell 2 as close to the rear wall surface 11 as possible. This will cause the gap between the first fan 3 and / or the heat-insulating shell 2 and the rear wall surface 11 to be very narrow, making the assembly difficulty increased. For example, the first fan 3 needs to be electrically connected to the power supply located outside the compartment 1 so as to be powered by the power supply. During assembly, the first fan 3 can be detachably mounted to the liner 4 along with the heat-insulating shell 2, and the first fan 3 is electrically connected to the power supply. In the case where the gap between the first fan 3 and / or the heat-insulating shell 2 and the rear wall surface 11 is very narrow, it is difficult to achieve the electrical connection between the first fan 3 and the power supply.

[0166] The heat-insulating housing 2 is provided with a communication inlet 21, so that the gas in the remaining space can flow into the first storage space 101 through the communication inlet 21 when the first fan 3 is running. The heat-insulating housing 2 may include a heat-insulating rear wall 22 that limits the first storage space 101 at the rear, and the communication inlet 21 is arranged in the heat-insulating rear wall 22 and located in the rear wall recess 111.

[0167] As described above, in the absence of the above-mentioned rear wall recess 111, in order to increase the depth dimension of the first storage space 101, it is necessary to bring the insulating rear wall 22 of the insulating shell 2 as close to the rear wall surface 11 as possible, resulting in a very narrow gap between the insulating rear wall 22 and the rear wall surface 11. The gas is greatly hindered from entering the first storage space 101 through the gap from the remaining space. In the case where the temperature of the first storage compartment 1 needs to be lowered, in order to meet the temperature requirement of the first storage compartment 1, it is necessary to increase the flow rate of the introduced gas or reduce the temperature of the introduced gas. This will lead to problems such as the required speed of the first fan 3 becoming larger, or the required speed of the compressor of the refrigeration appliance becoming higher. These problems will increase the energy consumption required for the refrigeration appliance or increase the performance requirements for the refrigeration appliance.

[0168] In an exemplary embodiment of the present application, by locating the connecting inlet 21 in the rear wall recess 111, it is possible to allow a larger spacing between the insulating rear wall 22 and the rear wall surface 11 while ensuring that the first storage space 101 has a larger depth dimension, thereby leaving a larger gap between the insulating rear wall 22 and the rear wall surface 11 for gas to flow through.

[0169] In this embodiment, the heat-insulating housing 2 may include a heat-insulating top wall 23 that bounds the first storage space 101 from above. The remaining space may include a second storage space 102 located above the heat-insulating top wall 23. The rear wall surface 11 may include an upper adjacent area 112 adjacent to the rear wall recess 111 above the rear wall recess 111. The rear wall recess 111 may include a recess bottom surface 1111 that is arranged offset backward relative to the upper adjacent area 112 and a first recess side surface 1112 located above the recess bottom surface 1111. The first recess side surface 1112 may extend forward from the recess bottom surface 1111 to the upper adjacent area 112. Therefore, the rear wall surface 11 is recessed in the direction away from the storage space 10 at the rear wall recess 111 in the direction from top to bottom (i.e., in the direction from the second storage space 102 to the first storage space 101).

[0170] As a result, the gas flowing from the second storage space 102 into the first storage space 101 cannot flow along a straight path from the second storage space 102 to the communication inlet 21. This helps to reduce the natural convection between the first storage space 101 and the second storage space 102 when the first fan 3 is turned off, and at the same time, when the first fan 3 is turned on, the gas introduced from the second storage space 102 into the first storage space 101 via the passage 6 can have a larger flow rate.

[0171] The upper adjoining region 112 can in particular delimit the second storage space 102 at the rear. The first recess side 1112 can be located above the insulating top wall 23. Alternatively, it is also feasible that the upper adjoining region 112 is located directly behind the first storage space 101.

[0172] Figure 4 Schematically shows Figure 3 A partial enlarged view of the part framed by dotted lines. Figure 4 It can be seen more clearly that a channel 6 for guiding gas from the second storage space 102 to the communication inlet 21 can be formed between the heat-insulating housing 2 and the rear wall surface 11. The channel 6 may include a first channel portion 61 located between the heat-insulating top wall 23 and the first recess side 1112 and a second channel portion 62 located between the heat-insulating rear wall 22 of the heat-insulating housing 2 and the recess bottom 1111.

[0173] See also Figure 4 As shown by the dotted arrow in , the channel 6 is tortuous. The first channel portion 61 may extend from the second storage space 102 along the depth direction D to the second channel portion 62, and the second channel portion 62 may extend along the height direction H to the connecting inlet 21. When the first fan 3 is turned off, the natural convection between the first storage space 101 and the second storage space 102 may be reduced by using such a tortuous channel 6. The channel 6 may have a larger flow cross-sectional area. When the first fan 3 is turned on, the gas can be introduced from the second storage space 102 to the first storage space 101 via the channel 6 at a larger flow rate.

[0174] like Figure 4As shown, the distance d1 between the surface area of ​​the heat-insulating top wall 23 opposite to the first recess side 1112 and the first recess side 1112 may be smaller than the distance d2 between the surface area of ​​the heat-insulating rear wall 22 opposite to the recess bottom 1111 and the recess bottom 1111. By setting such a differentiated distance, the natural convection between the first storage space 101 and the second storage space 102 can be reduced when the first fan 3 is turned off, and a larger gap is left between the heat-insulating rear wall 22 and the recess bottom 1111. The larger gap between the heat-insulating rear wall 22 and the recess bottom 1111 will not have much impact on the natural convection between the first storage space 101 and the second storage space 102, and can make the assembly process more convenient.

[0175] The outer opening 210 of the communication inlet 21 is open to the remaining space. The gas flowing from the second storage space 102 to the second storage space 102 via the passage 6 enters the communication inlet 21 through the outer opening 210. The communication inlet 21 can be arranged in particular so that the gas exchange between the first storage space 101 and the remaining space is suppressed when the first fan 3 is not running.

[0176] like Figure 4 As shown, the communication inlet 21 may penetrate the heat-insulating rear wall 22 of the heat-insulating housing 2 along a serpentine path, wherein the serpentine path has at least one bend.

[0177] In particular, the serpentine path has a bending angle of at least 180° and / or has at least two bending portions with an angle of more than 90°. The bending angle may represent an angle at which the flow direction of the gas is deflected along the serpentine path.

[0178] The serpentine path of the communication inlet 21 may include, for example, a Z-shaped section. The serpentine path of the communication inlet 21 may also include a U-shaped section.

[0179] The communication inlet 21 may be kept in a normally open state. The refrigeration appliance may not be provided with a damper for controlling the opening and closing state of the communication inlet 21 .

[0180] When the first fan 3 is turned off, the communication inlet 21 can hinder the gas exchange between the first storage space 101 and the second storage space 102. When the first fan 3 is turned on, the gas can flow from the second storage space 102 to the first storage space 101 through the communication inlet 21 driven by the first fan 3. By using the serpentine path, the communication inlet 21 can still leave a larger flow cross section when hindering the gas convection between the first storage space 101 and the second storage space 102, so as to allow a larger flow of air to pass when the first fan 3 is turned on.

[0181] For example, the communication opening may have a diameter greater than 250 mm. 2 and / or less than 1000mm2 Minimum flow cross-sectional area.

[0182] The heat-insulating housing 2 may be provided with a communication outlet 25 for guiding the gas from the first storage space 101 to the remaining space.

[0183] The communication outlet 25 can be kept in a normally open state similar to the communication inlet 21. That is, all the communication outlets 25 and the communication inlet 21 for connecting the first storage space 101 fluid to the remaining space are always kept open. The communication outlet 25 can be constructed in a similar manner to the communication inlet 21, for example, it can pass through the heat-insulating housing 2 along a serpentine path.

[0184] It is particularly advantageous to combine the normally open communication inlet 21 and the communication outlet 25 with the above-described tortuous passage 6 for guiding the gas from the second storage space 102 to the communication inlet 21. This helps ensure that the temperature of the first storage space 101 is still accurately controlled without the damper.

[0185] Optionally, the heat-insulating top wall 23 is provided with a top wall recess 231 which is recessed downward on its upper surface. The top wall recess 231 may be opposite to the first recess side wall 5132 along the height direction H, so that the gap between the first recess side 1112 and the heat-insulating housing 2 is at least partially blocked in the front by the heat-insulating top wall 23. Thus, the risk of foreign matter entering the channel 6 can be reduced. The foreign matter may include, for example, water, objects to be cooled and their debris, etc. The user will hardly notice the existence of the rear wall recess 111 from the front.

[0186] Figure 5 The compartment 1 and the heat-insulating housing 2 of the refrigeration appliance according to the exemplary embodiment of the present application are schematically shown in an exploded view.

[0187] like Figure 5 As shown, the compartment 1 may be surrounded by the inner liner 4 of the refrigerating appliance. The refrigerating appliance may also be provided with an air duct 50 located in the compartment 1, and the air duct 50 is configured to supply cooling gas to the storage space 10 through at least one air duct outlet 501. The storage space 10 of the compartment 1 may be provided with a rear wall surface 11 that bounds the storage space 10 at the rear. The air duct 50 may be at least partially located behind the rear wall surface 11.

[0188] The at least one air duct outlet 501 may be arranged above the heat-insulating housing 2. Therefore, the cooling gas introduced into the storage space 10 from the air duct 50 flows into the remaining space, and does not flow directly into the first storage space 101. When necessary, the cooling gas can be introduced from the remaining space into the first storage space 101. This helps to achieve the desired temperature in different temperature zones of the storage space. Optionally, the outer opening 210 (at Figure 5502 (not visible in the figure) is arranged to be offset rearwardly relative to any one of the at least one air duct outlets 501.

[0189] The rear wall surface 11 may be provided with a rear wall recess 111 that is recessed backward. The heat insulating housing 2 is, for example, detachably arranged in the compartment 1. A portion of the heat insulating housing 2 may be located in the rear wall recess 111, making the structure of the refrigeration appliance more compact.

[0190] The rear wall surface 11 may include, in particular, a side adjacent region 113 adjacent to the rear wall recess 111 in the width direction W. The rear wall recess 111 may include a recess bottom surface 1111 arranged offset rearwardly relative to the side adjacent region 113 and a second recess side surface 1113 arranged side by side with the recess bottom surface 1111 in the width direction W. The second recess side surface 1113 may extend forward from the recess bottom surface 1111 to the side adjacent region 113. The rear wall recess 111 is formed so that the rear wall is recessed in the direction away from the storage space 10 at the rear wall recess 111 in the width direction W. The side adjacent region 113 may be located directly behind the heat-insulating housing 2.

[0191] The storage space 10 may be provided with a return air port 12 so that the gas in the storage space 10 can flow out through the return air port 12 and flow to the evaporator chamber 95 of the refrigeration appliance. The return air port 12 may be formed at the rear wall surface 11.

[0192] The return air vent 12 may be located directly behind the first storage space 101. The return air vent 12 may be arranged to be staggered with the outer opening 210 of the first fan 3 and / or the communication inlet 21 in the width direction W. Alternatively or additionally, the return air vent 12 may be arranged to be lower than the outer opening 210 of the first fan 3 and / or the communication inlet 21 in the height direction H. The return air vent 12 may be arranged in the side adjacent area 113 in particular.

[0193] Figure 5 The dotted line in illustratively shows the air duct 50. The air duct 50 may extend from one side of the rear wall recess 111 in the width direction W to the upper side of the rear wall recess 111 so as to bypass the rear wall recess 111. Thus, the air duct 50 may leave space for arranging the first fan 3 or the heat insulation housing 2.

[0194] Optionally, the air duct 50 may include a first air duct section 502 located directly behind the first storage space 101 and a second air duct section 503 located above the first storage space 101 .

[0195] Optionally, the first air duct section 502 does not have an air duct outlet 501 for supplying cooling gas into the storage space 10. The at least one air duct outlet 501 is disposed in the second air duct section 503.

[0196] like Figure 5As shown, the first air duct section 502 may be narrower than the second air duct section 503. Below the second air duct section 503 and at a position transversely arranged with the first air duct section 502, at least a portion of the heat-insulating housing 2 and / or at least a portion of the first fan 3 and / or at least a portion of a connector for connecting the electrical device in the heat-insulating housing 2 to a power supply outside the compartment 1 are provided.

[0197] Figure 6 The compartment 1 of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown in a cross-sectional view, wherein the cross-sectional position can be referred to as Figure 1 Section line BB is shown.

[0198] like Figure 6 As shown, the rear wall surface 11 may be provided with a rear wall recess 111 recessed rearward and a side adjacent region 113 adjacent to the rear wall recess 111 in the width direction W. The rear wall recess 111 may include a recess bottom surface 1111 arranged to be offset rearward relative to the side adjacent region 113 and a second recess side surface 1113 arranged side by side with the recess bottom surface 1111 in the width direction W, and the second recess side surface 1113 extends forward from the recess bottom surface 1111 to the side adjacent region 113. The heat-insulating rear wall 22 of the heat-insulating housing 2 may include a first rear wall section 221 and a second rear wall section 222 arranged side by side along the width direction W, wherein the second rear wall section 222 is offset rearward relative to the first rear wall section 221. The second rear wall section 222 may be at least partially located in the rear wall recess 111, and the first rear wall section 221 may be opposite to the side adjacent region 113 of the rear wall surface 11. The rear wall recess 111 can be completely shielded from the front by the heat-insulating housing 2 , for example.

[0199] The first fan 3 can be arranged in particular at the second rear wall section 222. In front of the first fan 3 and the first rear wall section 221, a regular space can be reserved for accommodating items to be cooled.

[0200] For example, the refrigeration appliance includes a drawer movably arranged in the first storage space 101. The rear wall of the drawer may be formed flat so that the accommodating space of the drawer is regular. The first rear wall section 221 and the first fan 3 may be arranged side by side in the width direction W. The projections of the first rear wall section 221 and the first fan 3 along the width direction W may overlap each other.

[0201] The communication inlet 21 may be disposed at the second rear wall section 222 . This helps to optimize the gas flow path within the storage space 10 .

[0202] The return air outlet 12 disposed in the side adjacent area 113 may be offset forward relative to the bottom surface 1111 of the recess, such as Figure 5As shown. The outer opening 210 of the first fan 3 and / or the communication inlet 21 may be arranged to be offset backward relative to the return air port 12. The return air port 12 and the communication inlet 21 are not directly fluidly connected along a straight path. Although the return air port 12 and the communication inlet 21 are both located at the rear of the storage space 10, the airflow flowing from the second storage space 102 to the first storage space 101 and the airflow flowing from the first storage space 101 to the return air port 12 can still be prevented from interfering with each other.

[0203] Figure 6 It is also shown that the air duct 50, in particular the first air duct section 502, can extend at least partially directly behind the first rear wall section 221, while completely avoiding the second rear wall section 222. The projections of the first air duct section 502 and the first rear wall section 221 in the depth direction D can overlap each other. The projections of the air duct 50 and the first rear wall section 221 in the depth direction D may not overlap at all.

[0204] Figure 7 The compartment 1 and the heat-insulating housing 2 of the refrigeration appliance according to the exemplary embodiment of the present application are schematically shown in an exploded view.

[0205] like Figure 7 As shown, the refrigeration appliance may be provided with an inner liner 4 for enclosing a compartment 1 and an air duct assembly 5 for forming an air duct 50. The air duct assembly 5 may be arranged in the compartment 1, for example, at the rear wall of the inner liner 4. Optionally, the air duct assembly 5 may also be arranged at other positions in the compartment 1, for example, at the side wall or top wall of the inner liner 4. The air duct 50 may be configured to supply cooling gas to the storage space 10. The air duct assembly 5 may be provided with an air duct cover plate 51, which is arranged in the compartment 1 between the storage space 10 and the air duct 50 for supplying cooling gas to the storage space 10. The air duct cover plate 51 may, for example, limit the storage space 10 at the rear. In other words, the rear wall surface 11 of the storage space 10 may be formed by the air duct cover plate 51.

[0206] The air duct assembly 5 may be provided with a receiving recess 52 that is recessed in a direction away from the storage space 10. The first fan 3 and / or the heat-insulating shell 2 may be at least partially located in the receiving recess 52. In this embodiment, the receiving recess 52 is the rear wall recess 111. The features and advantages described herein for the rear wall recess 111 may also be similarly applicable to the receiving recess 52. In the case where the air duct assembly 5 is arranged at other positions in the inner liner 4, the receiving recess 52 may also accommodate at least a portion of the first fan 3 and / or the heat-insulating shell 2. Furthermore, in the case where the air duct assembly 5 is arranged at other positions in the inner liner 4, the receiving recess 52 and the air duct cover plate 51 may have features and advantages corresponding to the features and advantages described herein for the rear wall recess 111 and the rear wall surface 11.

[0207] Figure 8The heat-insulating housing 2 of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown from the rear. Figure 8 As shown, the heat-insulating housing 2 may include at least a heat-insulating top wall 23 and a heat-insulating rear wall 22. The heat-insulating rear wall 22 may include a first rear wall section 221 and a second rear wall section 222 arranged side by side in the width direction W, wherein the second rear wall section 222 is offset rearward relative to the first rear wall section 221. The second rear wall section 222 may be at least partially located in the rear wall recess 111, and the first rear wall section 221 may be opposite to the side adjacent area 113 of the rear wall surface 11. The communication inlet 21 may be provided at the second rear wall section 222.

[0208] The top wall recess 231 may be located directly above the second rear wall section 222 and may not extend to directly above the first rear wall section 221 .

[0209] Figure 8 It is also shown that the refrigeration appliance may be provided with a first connector 71, which is attached to the heat-insulating housing 2 via a wire 72. The first connector 71 can be used to electrically connect the electrical device disposed in the heat-insulating housing 2 to a power supply and / or a controller located outside the heat-insulating housing 2, in particular outside the compartment 1. The electrical device disposed in the heat-insulating housing 2 may include, for example, at least one of the following: a first fan 3, a sensor for detecting storage conditions (such as temperature, humidity) in the first storage space 101, and a display screen mounted on the heat-insulating housing 2.

[0210] Fig. 9 A partial enlarged view of a refrigeration appliance according to an exemplary embodiment of the present application is schematically shown. Fig. 9 Perspective and Figure 4 similar.

[0211] like Fig. 9 As shown, the first connector 71 can be attached to the heat-insulating housing 2 via a wire 72. The wire 72 can electrically connect the first connector 71 to an electrical device disposed in the heat-insulating housing 2. The refrigeration appliance may further include a second connector 73, which is used to be electrically connected to the first connector 71 to achieve electrical connection between the first connector 71 and a power supply and / or a controller located outside the compartment 1.

[0212] According to an exemplary embodiment of the present application, the second connector 73 may be disposed at the rear wall surface 11. The first connector 71 and / or the second connector 73 may be at least partially located in the rear wall recess 111. Thus, the installation process can be made more convenient while ensuring that the first storage space 101 has a larger volume. In particular, by utilizing the rearwardly recessed rear wall recess 111, the first connector 71 can be connected to the second connector 73 in an easy-to-operate manner. Having the first connector 71 and the second connector 73 located in the rear wall recess 111 prevents the first connector 71 and the second connector 73 from occupying the volume of the storage space and does not hinder the gas flowing through the aforementioned channel 6.

[0213] The second connector 73 may be located, for example, behind the air duct cover 51. Alternatively, the second connector 73 may be disposed in the rear wall of the inner container 4. Figure 7 and Fig. 9 The air duct cover plate 51 may be provided with a cover plate opening 512 at the rear wall recess 111, so that the first connector 71 can be connected to the second connector 73 through the cover plate opening 512. By using the rear wall recess 111 and the cover plate opening 512, the first connector 71 can be plugged into the second connector 73 more conveniently.

[0214] Fig.10 The compartment 1 of the refrigeration appliance according to an exemplary embodiment of the present application is schematically shown. In this embodiment, the compartment 1 has a storage space 10. An air duct assembly 5 for forming an air duct 50 is arranged in the compartment 1. An air duct cover plate 51 is arranged between the storage space 10 and the air duct 50 in the compartment 1. The heat-insulating housing 2 is arranged in the storage space, and a first storage space 101 is separated in the storage space 10. The heat-insulating housing 2 is located in front of the air duct assembly 5. The rear wall recess 111 / accommodating recess 52 can be at least substantially, in particular completely, shielded by the heat-insulating housing 2 in the front.

[0215] Fig.11 The compartment 1 of the refrigeration appliance according to an exemplary embodiment of the present application is schematically shown. In this embodiment, the compartment 1 of the refrigeration appliance has a storage space 10. The refrigeration appliance is also provided with an air duct cover plate 51, which is arranged in the compartment 1 between the storage space 10 and an air duct 50 for supplying cooling gas into the storage space 10. The air duct 50 is at least partially formed between the air duct cover plate 51 and the first compartment wall 13 of the compartment 1. The first compartment wall 13 is, for example, the rear wall of the compartment 1. In other embodiments, the first compartment wall 13 may also be a wall in other directions of the compartment 1, such as a side wall.

[0216] The air duct cover plate 51 may be formed with a cover plate recess 513 that is recessed in a direction away from the storage space 10. Figure 7The cover plate recess 513 can be used as the rear wall recess 111 or the accommodating recess 52 described above. The cover plate recess 513 is isolated from the air duct 50. The refrigeration appliance is also provided with a shielding cover 8, which can be detachably mounted to the air duct cover plate 51 to shield the cover plate recess 513. Therefore, the cover plate recess 513 is Fig.11 Not visible in.

[0217] Generally, the air duct cover of refrigeration appliances has low versatility. Different models of refrigeration appliances can only use air duct cover plates with different structures. This means that the air duct cover plates need to be molded and manufactured separately for different models of refrigeration appliances. This not only prolongs the production cycle of the product, but also greatly increases the product cost.

[0218] According to an exemplary embodiment of the present application, the air duct cover plate 51 having the same configuration can be used in refrigeration appliances of different models and can be adapted to different layouts in the compartment 1 of the refrigeration appliance, thereby significantly reducing costs.

[0219] For example, the air duct cover 51 can be used in Figure 7 In the embodiment shown, the cover recess 513 of the air duct cover 51 can form the receiving recess 52 and / or the rear wall recess 111 so as to at least partially limit the storage space 10 at the rear. Furthermore, the heat insulating housing 2 and / or the first fan 3 can be arranged in the cover recess 513.

[0220] The air duct cover plate 51 can also be used in the compartment 1 of a refrigeration appliance that does not have a heat-insulating housing 2. Figure 8 As shown, the heat insulating housing 2 is not provided in front of the air duct cover plate 51, and the cover plate recess 513 can be shielded by the shielding cover 8 in front. It can be imagined that when the shielding cover 8 is not installed, the cover plate recess 513 is exposed to the storage space 10. With the help of the shielding cover 8, the cover plate recess 513 can be separated from the storage space 10, and the cover plate recess 513 is no longer exposed to the user's field of vision.

[0221] The cover plate recess 513 is isolated from the air duct 50, which means that the cover plate recess 513 is not a part of the air duct 50 and is not connected to the air duct 50. The shielding cover 8 is different from the air duct cover plate 51 used to shield the air duct 50. Figure 5 , the cover plate recess 513 (here forming the rear wall recess 111) is formed outside the air duct 50. In particular, the projections of the cover plate recess 513 and the air duct 50 in the depth direction D do not overlap. Figure 5 It can be seen that the air duct 50 may include a first air duct section 502 arranged side by side with the cover plate recess 513 in the width direction W and a second air duct section 503 located above the cover plate recess 513. Figure 5 The installation position of the shielding cover 8 is schematically shown by the dot-dash line.

[0222] Fig.12 The figure schematically shows an air duct cover plate 51 of a refrigeration appliance according to an exemplary embodiment of the present application.

[0223] like Fig.12 As shown, the air duct cover plate 51 may include an adjacent area 514 adjacent to the cover plate recess 513. The cover plate recess 513 may include a recess bottom wall 5131 arranged offset in a direction away from the storage space 10 relative to the adjacent area 514 and a recess side wall 5132 extending from the recess bottom wall 5131 to the adjacent area 514. The adjacent area 514 may, for example, form the upper adjacent area 112 and / or the side adjacent area 113 described above. It should be understood that the description related to the rear wall recess 111 and the accommodating recess 52 above may also be applicable to the cover plate recess 513.

[0224] Optionally, the air duct cover plate 51 may be provided with a cover plate opening 512 penetrating the air duct cover plate 51 at the bottom wall 5131 of the recess. The cover plate opening 512 may be shielded by the shielding cover 8 and will not be exposed to the storage space 10. Thus, reliability may be improved.

[0225] exist Fig.12 The shielding cover 8 is schematically shown by a dotted line in FIG. The width dimension of the shielding cover 8 may be greater than one third of the width dimension of the air duct cover plate 51 and less than two thirds of the width dimension of the air duct cover plate 51 .

[0226] The air duct cover plate 51 may be provided with a return air port 12, so that the gas in the storage space 10 can flow out through the return air port 12 and flow to the evaporator chamber 95 of the refrigeration appliance. The return air port 12 and the shielding cover 8 may be arranged side by side in the width direction W.

[0227] The air duct cover plate 51 may be provided with a first mounting structure, which is configured to allow the shielding cover 8 for shielding the rear wall recess 111 to be detachably mounted to the air duct cover plate 51 by means of the first mounting structure. The first mounting structure may, for example, include a first snap structure 511 disposed at the side wall 5132 of the recess.

[0228] Fig.13 The figure schematically shows a shielding cover 8 of a refrigeration appliance according to an exemplary embodiment of the present application. Fig.14 A partial 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 Fig.11 Section line CC shown.

[0229] like Fig.13 and Fig.14As shown, the shielding cover 8 may include a shielding cover body 81. The shielding cover body 81 may be arranged to be spaced apart from the recess bottom wall 5131 and located between the recess bottom wall 5131 and the storage space 10. The shielding cover body 81 may shield the cover plate recess 513 in the front. The shielding cover body 81 may be adjacent to and flush with the adjacent area 514. Thus, the shielding cover 8 may form a flat rear wall surface 11 of the storage space 10 together with the air duct cover plate 51.

[0230] The shielding cover body 81 may include a first cover portion 811 and a second cover portion 812. The first cover portion 811 may be located above the second cover portion 812. The second cover portion 812 may be particularly offset backward relative to the first cover portion 811. Fig.12 The second cover portion 812 may be arranged flush with the return air outlet 12 in the height direction H and the depth direction D, and arranged side by side with the return air outlet 12 in the width direction W.

[0231] Optionally, the shielding cover 8 may include a support column 82 extending from the shielding cover body 81 in a direction away from the storage space 10. The support column 82 may abut against the recess bottom wall 5131. Thus, the shielding cover 8 may be made more stable and reliable. Even if the shielding cover 8 is pushed by cooling objects in the storage space 10 or by a user during use, the shielding cover 8 is not easily deformed or displaced.

[0232] The shielding cover 8 may be provided with a second snap-fit ​​structure 83 extending from the shielding cover body 81 in a direction away from the storage space 10, for example. The first snap-fit ​​structure 511 of the air duct cover plate 51 and the second snap-fit ​​structure 83 of the shielding cover 8 may be arranged so that the second snap-fit ​​structure 83 can form a snap-fit ​​fit with the first snap-fit ​​structure 511 by the shielding cover 8 moving relative to the air duct cover plate 51 in a direction perpendicular to the main plane of the air duct cover plate 51. For example, during the assembly process, the shielding cover 8 may be mounted backward to the air duct cover plate 51 in the depth direction D. The shielding cover 8 can be mounted in a simple manner. In a refrigeration appliance without the shielding cover 8, the function of the air duct cover plate 51 will not be adversely affected.

[0233] The compartment 1 may include a second compartment wall 14 adjacent to the first compartment wall 13. The second compartment wall 14 may be, for example, the bottom wall of the compartment 1. The shielding cover 8 may also include, for example, a first flange 84 extending from an edge of the shielding cover body 81 adjacent to the second compartment wall 14 in a direction away from the first compartment wall 13. The first flange 84 may be connected to the second compartment wall 14. Through the first flange 84, the shielding cover 8 can be installed in place more stably, and foreign matter can be prevented from entering the rear of the shielding cover 8.

[0234] like Fig.14As shown, the refrigeration appliance may include a container 99 for accommodating items to be cooled in the storage space 10. The container 99 may be arranged in front of the shielding cover 8. For example, in some refrigeration appliances, the container 99 may be arranged at the bottom of the storage space 10 instead of the insulating shell 2. The container 99 may be configured to be transparent or translucent, so that the cover plate recess 513 cannot be shielded in front when the shielding cover 8 is not provided. The container 99 may have a relatively small size, in particular a height size. The height size of the shielding cover 8 may not be less than the height size of the container 99.

[0235] In another embodiment, it is also feasible that the height dimension of the container 99 is greater than the height dimension of the shielding cover 8. The container 99 can completely block the shielding cover 8 in the front.

[0236] Fig.15 Schematically shows Fig.14 A partial enlarged view of the circled portion. Fig.15 The connection of the first flange 84 to the second compartment wall 14 can be more clearly seen.

[0237] The second compartment wall 14 may be provided with a locking groove 141, for example. The first flange 84 may be provided with a locking protrusion 841 protruding toward the second compartment wall 14 on the side facing the second compartment wall 14. The locking protrusion 841 may be embedded in the locking groove 141 to connect the first flange 84 to the second compartment wall 14. The lower edge of the locking protrusion 841 may be formed to be inclined downward in a forward direction (i.e., away from the first compartment wall 13). The first flange 84 may be fixedly connected to the second compartment wall 14 in a manner that facilitates installation by means of the locking protrusion 841.

[0238] like Fig.15 As shown, the air duct cover plate 51 may be provided with a second flange 515 extending in a direction away from the first compartment wall 13 at its edge adjacent to the second compartment wall 14. The second flange 515 may extend between the first flange 84 and the second compartment wall 14 and be provided with a through hole 5151. The locking protrusion 841 may pass through the through hole 5151 and be embedded in the locking groove 141. The first flange 84 serves to fix the second flange 515 to the second compartment wall 14. Thus, the shielding cover 8, the air duct cover plate 51 and the second compartment wall 14 can be fixed together in a manner that facilitates installation. This connection method is particularly helpful in preventing foreign matter from entering the gap between the shielding cover 8 and the air duct cover plate 51 and between the air duct cover plate 51 and the first compartment wall 13 from the storage space 10.

[0239] 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.
