Description

Refrigerating appliance

Technical Field

The present application relates to the field of household appliances, and in particular, to a refrigeration appliance.

Background

Nowadays, with the improvement of living standard of people, the refrigerating appliance has been put into thousands of households, such as refrigerators, sideboards, etc. Refrigeration appliances generally include a cabinet and a door movable relative to the cabinet. The door may be formed with a storage space for storing articles therein to facilitate use by a user.

At present, the door of the refrigerator remains to be improved in structure and function. For example, the door of the existing refrigeration appliance has the defects of simple function, large volume, heavy weight and the like.

Disclosure of Invention

It is an object of embodiments of the present application to provide an improved refrigeration appliance to improve the door assembly of the refrigeration appliance. In particular, the door assembly can have a variety of functions, a compact structure, and/or a small thickness.

According to a first aspect of the present application, embodiments of the present application provide a refrigeration appliance comprising: a case having a storage chamber; and a door assembly for closing the storage chamber, comprising: an inner door movably connected to the case; and an outer door movably disposed at a side of the inner door opposite to the case, wherein in a closed state of the inner door and the outer door, the inner door has a first storage space at a rear side of the inner door toward the case and a second storage space at a front side of the inner door toward the outer door within a projection area of the outer door in a depth direction of the refrigerator, and projections of the first storage space and the second storage space in a length direction or a width direction of the inner door at least partially overlap.

Accordingly, the door assembly can have various functions and a compact structure. In particular, the door assembly can have a small thickness with a variety of functions.

According to an alternative embodiment of the present application, the first storage space is located within the storage chamber and is in gaseous communication with the storage chamber with the inner door closed. The first storage space can be cooled together with the storage chamber.

Alternatively or additionally, the second storage space is separated from the first storage space and the storage chamber in such a way that the flow of gas is insulated. Thereby, the heat insulation effect of the door assembly can be improved, and the thickness of the door assembly can be reduced. In addition, it also helps to diversify the functions of the door assembly.

Here, "isolated in a manner that isolates the gas flow" may mean that the two are isolated without the intention of establishing a gas flow, but should not be understood as being completely hermetically isolated.

According to an alternative embodiment of the application, the projections of the first storage space and the second storage space in the depth direction do not intersect. This is advantageous in providing a suitably versatile door storage space in a door assembly of limited thickness dimension.

According to an alternative embodiment of the present application, in a case where the outer door is in a closed state, an inter-door space is formed between the outer door and the inner door at a position corresponding to the first storage space in the depth direction. The door assembly may further include a seal coupled between the outer door and the inner door with the outer door in a closed state such that the inter-door space and the second storage space are hermetically isolated from an external environment. This helps to improve the insulating effect of the door assembly.

According to an alternative embodiment of the application, the portion of the inner door located between the inter-door space and the first storage space is configured as a heat insulating wall filled with foamed heat insulating material, by means of which the inter-door space is separated from the first storage space in a manner that isolates the flow of gas. Alternatively or additionally, the outer door may comprise a thermal insulation, wherein the thermal insulation overlaps with a thermal insulation wall of the inner door, seen in a depth direction of the refrigeration appliance. Accordingly, a significantly reduced temperature gradient may be formed between the storage chamber and the first storage space and the inter-door space, and between the inter-door space and the external environment. This helps to improve the overall insulating effect of the door assembly. The inner door and the outer door can jointly bear the heat insulation function, thereby being beneficial to reducing the thickness and weight of the inner door or the outer door and being beneficial to reducing the thickness and weight of the whole door assembly.

According to an alternative embodiment of the present application, the inter-door space has a smaller depth dimension and/or a higher operating temperature than the second storage space. Thereby, the convection of the gas in the inter-door space can be prevented, and the condensation of the moisture can be prevented.

According to an alternative embodiment of the present application, the inter-door space is in gaseous communication with and above the second storage space. This helps to prevent gas flow between the inter-door space and the second storage space.

According to an alternative embodiment of the present application, the depth dimension of the inter-door space is less than 10mm. This is particularly advantageous for the insulating effect of the inter-door space.

According to an alternative embodiment of the application, the depth dimension of the second storage space is more than 10 times the depth dimension of the inter-door space. This is advantageous for the storage function of the second storage space and for the insulation function of the inter-door space.

According to an alternative embodiment of the present application, the inner door includes an inner door body and a tub-shaped case. The inner door body may have an opening penetrating in a depth direction. The case may be disposed at the opening and open toward the outer door so as to define a second storage space. This not only facilitates manufacturing but also helps to achieve multiple functions of the door assembly.

According to an alternative embodiment of the application, the inner door further comprises a heat conducting member adapted to transfer heat between the storage compartment and the second storage space, the heat conducting member being mountable to the rear wall of the box body at a side facing the storage compartment. By means of the heat conducting member, heat exchange between the storage chamber and the second storage space can be enhanced.

According to an alternative embodiment of the present application, the heat conducting member is configured as an aluminum plate covering the rear wall of the case. Such a heat conducting member is easy to manufacture and install.

According to an alternative embodiment of the present application, the inner door further comprises a first storage unit arranged on the rear side of the inner door body to define a first storage space. This helps to improve the user's use experience.

According to an alternative embodiment of the present application, the inner door further comprises a mirror covering the front side of the inner door body in the depth direction corresponding to the first storage space. The inner door comprises, for example, a second storage unit for a cosmetic product, which is arranged in the second storage space. This helps to improve the user's use experience.

According to an alternative embodiment of the present application, the inner door further comprises a light emitting assembly and a light transmissive panel. The light-transmitting plate may cover the front side of the inner door body in a depth direction corresponding to the first storage space. The light emitting assembly may be disposed between the inner door body and the light transmitting plate such that light emitted from the light emitting assembly can pass through the light transmitting plate. Thereby, the light emitting assembly and the light transmitting plate can function as decoration and/or illumination.

According to an alternative embodiment of the present application, the light-transmitting panel comprises a transflective region allowing light emitted by the light-emitting assembly to pass through and a specular reflection region having a higher reflectivity than the transflective region. The light-transmitting plate can have an optimized decorative effect and multiple functions.

According to an alternative embodiment of the application, the outer door is configured as an at least translucent visible area in a position corresponding to the second storage space in the depth direction and as an opaque non-visible area in a position corresponding to the first storage space in the depth direction. This helps to improve the user's use experience.

Detailed Description

In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the present application.

First, for ease of understanding, returning to the description of the background section, the refrigeration appliance of the prior art has problems of single function, large volume, heavy weight, and the like of the door.

In view of 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, including: a case having a storage chamber; and a door assembly for closing the storage chamber, comprising: an inner door movably connected to the case; and an outer door movably disposed at a side of the inner door opposite to the cabinet, wherein in a closed state of the inner door and the outer door, the inner door has a first storage space at a rear side of the inner door toward the cabinet and a second storage space at a front side of the inner door toward the outer door within a projection area of the outer door in a depth direction of the refrigerator, and projections of the first storage space and the second storage space in a length direction or a width direction of the inner door overlap at least partially.

For a better understanding of the present application, exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

Before beginning the detailed description, it should be noted that directional terms used in the description refer to the normal use state of the refrigeration appliance for convenience of description and are not to be construed as absolute limitations on the corresponding features. In some of the drawings, the height direction H, the width direction W, and the depth direction D, which are perpendicular to each other, are schematically shown as arrows.

Fig. 1A, 1B and 1C schematically show perspective views of a refrigeration appliance according to an exemplary embodiment of the present application.

The refrigerator comprises a case 1 having a storage chamber 11; and a door assembly 2 for closing the storage chamber 11. The storage chamber 11 may be, for example, a refrigerating chamber. The door assembly 2 includes an inner door 21 and an outer door 22. The inner door 21 is movably connected to the cabinet 1. The outer door 22 is movably disposed at a side of the inner door 21 opposite to the case 1. The door assembly 2 is configured in the form of a "door-on-door". Fig. 1A shows the door assembly 2 as a whole in a closed state, in which the storage chamber 11 is closed by the door assembly 2. Fig. 1B shows the door assembly 2 as a whole in an open state, in which the storage chamber 11 is opened. Fig. 1C shows a state in which the inner door 21 is closed and the outer door 22 is opened.

As can be seen in conjunction with fig. 1A, 1B and 1C, in the closed state of the inner door 21 and the outer door 22, the inner door 21 has a first storage space 2101 located at the rear side of the inner door 21 toward the cabinet 1 and a second storage space 2102 located at the front side of the inner door 21 toward the outer door 22 in the projection area of the outer door 22 in the depth direction D of the refrigerator. The projections of the first storage space 2101 and the second storage space 2102 along the length direction or the width direction of the inner door 21 at least partially overlap.

The user can take and place the articles in the second storage space 2102 by simply opening the outer door 22, thereby facilitating the use of the user and reducing the loss of cold. Meanwhile, by the first storage space 2101 located at the rear side of the inner door 21, a door rear storage space located at the rear side of the entire door assembly 2 can also be provided for the user. Accordingly, the door assembly 2 of the refrigerator can have various functions. It is particularly advantageous that the projections of the first storage space 2101 and the second storage space 2102 in the height direction H of the refrigerator overlap at least partially in the depth direction D, so that the door assembly 2 can have a compact structure. In particular, the door assembly 2 can still have a small thickness with a diversified function. In addition, such a door assembly 2 can improve the force distribution of the door assembly 2 with reduced deformation in the case where the first storage space 2101 and the second storage space 2102 store articles.

Referring to fig. 1C, in the case where the inner door 21 is closed, the length direction of the inner door 21 may be in the same direction as the height direction H of the refrigerator, and the width direction of the inner door 21 may be in the same direction as the width direction W of the refrigerator.

Illustratively, the first storage space 2101 may be used for storing milk, eggs, beverages, and the like. The storage mode accords with the use habit of a user. The second storage space 2102 may be used, for example, to store cosmetic products for convenient use by a user. In particular, even if the user needs to open the second storage space 2102 for a long time or more frequently when using the items stored in the second storage space 2102, such as cosmetic products, the inner door 21 can be kept closed with the outer door 22 opened, thereby reducing the loss of cold. Of course, the first storage space 2101 and the second storage space 2102 may also be used for storing other types of items, for example, as desired by the user.

In this embodiment, the refrigerator may be implemented as a combination refrigerator having a refrigerating chamber and a freezing chamber, for example. Those skilled in the art will appreciate that the present application is equally applicable to other types of refrigerators, such as a refrigerator alone or a freezer. In addition, the present application can be applied to other refrigeration appliances other than a refrigerator, such as a wine cabinet, as needed. The present application is particularly applicable to domestic refrigeration appliances.

Referring to fig. 1B and 1C, with the inner door 21 closed, the first storage space 2101 may be located within the storage chamber 11, for example, and in gaseous communication with the storage chamber 11. The first storage space 2101 may be cooled together with the storage chamber 11 and may have a substantially equal operating temperature as the storage chamber 11.

The second storage space 2102 is separated from the first storage space 2101 and the storage chamber 11, for example, in a manner of isolating the flow of gas. Accordingly, there is substantially no convection between the second storage space 2102 and the first storage space 2101 and the storage chamber 11. This helps to further functionally distinguish the second storage space 2102 from the first storage space 2101. For example, the operating temperature of the second storage space 2102 may be set to be different from the operating temperature of the first storage space 2101, in particular, higher than the operating temperature of the first storage space 2101. The second storage space 2102 may be, for example, between 10 ℃ and 14 ℃, for example, set at 12 ℃. The operating temperature of the second storage space 2102 may be, for example, greater than 6 ℃ above the operating temperature of the storage chamber 11 and/or the first storage space 2101. The higher operating temperature of the second storage space 2102 advantageously prevents moisture condensation. The second storage space 2102 and the first storage space 2101 may also be set to have different working humidities, for example. This helps to further diversify the function of the door assembly 2.

Since the second storage space 2102 is partitioned from the first storage space 2101 and the storage chamber 11 by the inner door 21 in such a manner as to isolate the flow of gas, the inner door 21 and the outer door 22 can jointly assume a heat insulating function between the storage chamber 11 and the external environment. By means of the inner door 21 and the outer door 22, a significantly reduced temperature gradient can be established both between the storage compartment 11 and the second storage space 2102 and between the second storage space 2102 and the environment. Thereby, the heat insulating effect of the door assembly 2 can be improved, and the thickness of the door assembly 2 can be reduced. In particular, the thickness and weight of the outer door 22 can be reduced.

In addition, the items stored in the second storage space 2102 can be isolated from the items stored in the first storage space 2101 and the storage chamber 11. This is particularly advantageous for storing cosmetic products within the second storage space 2102, because the cosmetic products within the second storage space 2102 can be isolated from other items (e.g., meat, fish, dairy products, etc.) placed within the first storage space 2101 and the storage chamber 11, thereby avoiding contamination of the cosmetic products. Of course, those skilled in the art will appreciate that this design is also advantageous for cooled items other than cosmetic products, as contamination of the cooled items with one another can be avoided.

As can be seen in connection with fig. 1B and 1C, the projections of the first storage space 2101 and the second storage space 2102 in the depth direction D do not intersect. Thus, both the first storage space 2101 and the second storage space 2102 can provide a storage space having a sufficient thickness. This is advantageous in providing a suitable on-door storage space in a door assembly 2 of limited thickness dimension. The first storage space 2101 and the second storage space 2102 may be arranged substantially side by side in the height direction H, for example. The first storage space 2101 and the second storage space 2102 may also be arranged substantially side by side in the width direction W.

Alternatively, the outer door 22 is configured as an at least translucent visible region 221 at a position corresponding to the second storage space 2102 in the depth direction D and is configured as an opaque non-visible region 222 at a position corresponding to the first storage space 2101 in the depth direction D. The viewing area 221 may be formed to be transparent or translucent, for example, so that items located within the second storage space 2102 can be viewed through the outer door 22. With the outer door 22 closed, the user is able to directly see the second storage space 2102 and the items stored therein, which is advantageous for improving the user's use experience. At the same time, the non-viewable area 222 eliminates the need to fully visualize the space behind the outer door 22, which also helps to improve the user's use experience.

Fig. 2 schematically shows a cross-sectional view of a door assembly 2 according to an exemplary embodiment of the present application, the cross-sectional line of which is seen from section line A-A of fig. 1. As shown in fig. 2, the first storage space 2101 is at least partially located directly above the second storage space 2102. The projections of the first storage space 2101 and the second storage space 2102 in the height direction H overlap. It can be seen that the door assembly 2 has a compact structure and a small thickness.

Fig. 2 also shows that an inter-door space 2103 may be formed between the outer door 22 and the inner door 21 at a position corresponding to the first storage space 2101 in the depth direction D with the outer door 22 in a closed state. The door assembly 2 may further comprise a seal 23, which may be arranged on the outer door 22 and/or the inner door 21. The sealing member 23 may be connected between the outer door 22 and the inner door 21 with the outer door 22 in a closed state such that the inter-door space 2103 and the second storage space 2102 are hermetically isolated from the external environment. The inter-door space 2103 and the second storage space 2102 can be hermetically separated from the external environment by means of the sealing member 23, thereby reducing heat exchange between the inter-door space 2103 and the second storage space 2102 and the external environment. This helps to improve the insulating effect of the door assembly 2.

The portion of the inner door 21 between the inter-door space 2103 and the first storage space 2101 may be configured as a heat insulation wall filled with a foamed heat insulation material. The inter-door space 2103 may be separated from the first storage space 2101 by the heat insulating wall in such a manner as to isolate the flow of gas. The inter-door space 2103 may have a higher operating temperature than the first storage space 2101 and the storage chamber 11. The operating temperature of the inter-door space 2103 may be set, for example, between 18 ℃ and 22 ℃, for example, at 20 ℃. By means of said insulating wall, it is advantageously possible to prevent moisture condensation from occurring at the inter-door space 2103 and/or the seal 23.

The outer door 22 may include a heat insulating portion overlapping with the heat insulating wall of the inner door 21 as viewed in the depth direction D of the refrigerator. As can be seen from fig. 2, at least the first storage space 2101, the heat insulation wall of the inner door 21, the inter-door space 2103 and the heat insulation part of the outer door 22 are spaced between the storage chamber 11 of the refrigerator and the external environment, the storage chamber 11 and the first storage space 2101 are spaced apart from the inter-door space 2103 in a heat insulation manner, and the inter-door space 2103 is also spaced apart from the external environment in a heat insulation manner. Accordingly, a significantly reduced temperature gradient may be formed between the storage chamber 11 and the first storage space 2101 and the inter-door space 2103, and between the inter-door space 2103 and the external environment. This helps to improve the overall insulating effect of the door assembly 2. The heat insulating wall of the inner door 21 and the heat insulating portion of the outer door 22 can jointly assume a heat insulating function. This structure can reduce the thermal insulation requirement for each of the inner door 21 and the outer door 22, as compared to the thermal insulation function carried by the inner door 21 or the outer door 22 alone, thereby contributing to a reduction in the thickness and weight of the inner door 21 or the outer door 22 carrying the thermal insulation function, and to a reduction in the thickness of the entire door assembly 2. The heat insulating portion of the outer door 22 may be filled with a heat insulating material, for example, a foamed heat insulating material.

The inter-door space 2103 may have, inter alia, a smaller depth dimension than the second storage space 2102. The smaller depth dimension makes gas flow less likely to occur in the inter-door space 2103. As shown in fig. 2, the inter-door space 2103 is substantially surrounded by the seal 23, the inner door 21, and the outer door 22, and communicates only with the second storage space 2102. In the case where the inter-door space 2103 has a small depth dimension, the gas in the inter-door space 2103 can be kept stationary. Thereby, convection of the gas in the inter-door space 2103 can be prevented, and heat exchange between the inter-door space 2103 and other spaces (including, for example, the external environment and the second storage space 2102) can be effectively reduced. With the outer door 22 closed, a substantially static air layer is formed within the inter-door space 2103, which gives the inter-door space 2103 itself an insulating effect, so that the insulating effect of the door assembly 2 as a whole can be improved. The heat insulating effect of the door assembly 2 can be improved particularly by forming a heat insulating air layer between the heat insulating wall of the inner door 21 and the heat insulating portion of the outer door 22. At the same time, the weight of the door assembly 2 can be reduced. The depth dimension of the inter-door space 2103 may be, for example, less than 10mm, and in particular, may be less than 5mm. Depth dimensions of less than 10mm, in particular less than 5mm, are proved to be particularly advantageous for the insulating effect of the inter-door space 2103. Alternatively or additionally, the depth dimension of the second storage space 2102 is more than 10 times the depth dimension of the inter-door space 2103. The second storage space 2102 may have a depth dimension suitable for storing items.

The inter-door space 2103 may have a higher operating temperature, in particular, than the second storage space 2102. The higher operating temperature of the inter-door space 2103 helps to prevent moisture condensation at the inter-door space 2103. For example, the operating temperature of the inter-door space 2103 may be greater than 6 ℃ above the operating temperature of the second storage space 2102.

The area of the inter-door space 2103 may be, in particular, greater than or equal to the area of the second storage space 2102, as viewed in the depth direction. The larger area and smaller depth dimension can advantageously reduce the flow of gas within the inter-door space 2103, thereby improving the insulating effect of the inter-door space 2103.

As shown in fig. 2, the inter-door space 2103 may be in gaseous communication with the second storage space 2102 and located above the second storage space 2102. This helps prevent gas flow between the inter-door space 2103 and the second storage space 2102. Between the inter-door space 2103 and the second storage space 2102, which are in gaseous communication with each other, cooler air will be deposited in the lower second storage space 2102 and warmer air will be located in the upper inter-door space 2103. If the inter-door space 2103 were in turn positioned below the second storage space 2102, the air within the cooled second storage space 2102 would tend to flow downward into the inter-door space 2103 and the warmer air within the inter-door space 2103 would flow upward into the second storage space 2102. This will cause convection between the second storage space 2102 and the interdoor space 2103.

The inner door 21 is further described below in connection with fig. 3. Fig. 3 schematically shows an exploded view of the inner door 21 according to an exemplary embodiment of the present application.

Referring to fig. 2 and 3, the inner door 21 may include an inner door body 211 and a tub-shaped case 212. The inner door body 211 may have an opening 2111 penetrating in the depth direction D. The cassette 212 may be disposed at the opening 2111 and open toward the outer door 22 to define a second storage space 2102. The inner door main body 211 is formed as a separate component from the case 212 defining the second storage space 2102. This not only facilitates manufacturing but also helps to achieve a variety of functions of the door assembly 2. For example, the inner door body 211 may be configured as a heat insulator filled with a foamed heat insulating material, which includes, for example, a heat insulating wall between the inter-door space 2103 and the first storage space 2101. The cassette 212 may be made of plastic, for example. The case 212 may be constructed as a thin-walled member having a relatively thin thickness. The case 212 may have a high heat transfer coefficient with respect to the inner door body 211.

Unlike the first storage space 2101, heat exchange between the second storage space 2102 and the storage chamber 11 can be achieved by means of heat conduction rather than heat convection. The cassette 212 separates the second storage space 2102 from the storage chamber 11, for example, in a manner that isolates the flow of gas. It should be appreciated that a completely airtight seal between the second storage space 2102 and the storage chamber 11 need not be achieved. For example, the top of the cassette 212 may be provided with an elongated aperture that allows the passage of gas. Alternatively, the case 212 and the inner door body 211 need not be connected in a completely airtight manner. By "the case 212 separates the second storage space 2102 from the storage chamber 11 in such a way that the gas flow is insulated" is meant, in particular, that the case 212 is not provided with air inlet holes and air outlet holes for forming a gas convection.

The inner door 21 further includes, for example, a heat conductive member 213 for transferring heat between the storage chamber 11 and the second storage space 2102. The heat conductive member 213 may be mounted to a rear wall of the case 212 at a side facing the storage chamber 11. With the heat conductive member 213, heat exchange between the storage chamber 11 and the second storage space 2102 can be enhanced. The heat conductive member 213 may be formed of an aluminum plate, which may cover a rear wall of the case 212, for example. Obviously, the heat conductive member 213 is made of a material having a high heat conductivity coefficient. In particular, the heat conductive member 213 is made of a material having a higher heat conductivity than the case 212 and the inner door body 211.

The inner door 21 may include, for example, a first storage unit 214 disposed on a rear side of the inner door body 211 to define a first storage space 2101. The first storage unit 214 may include, for example, at least one door shelf suspended from the inner door body 211. The inner door 21 may further include a second storage unit 216 for cosmetic products. The second storage unit 216 may be disposed within the second storage space 2102.

Optionally, the inner door 21 further comprises a light emitting assembly 217 and a light transmitting plate 218. The light-transmitting plate 218 may cover the front side of the inner door body 211 in the depth direction D corresponding to the first storage space 2101. The light emitting assembly 217 may be disposed between the inner door body 211 and the light transmitting plate 218 such that light emitted from the light emitting assembly 217 can pass through the light transmitting plate 218. Thus, the light emitting assembly 217 and the light transmitting plate 218 can function as decoration and/or illumination. The light emitting assembly 217 may be configured to be automatically opened when the outer door 22 is opened and to be automatically closed when the outer door 22 is closed, for example. Alternatively, the light emitting assembly 217 may be configured to emit light toward the second storage space 2102, thereby illuminating the second storage space 2102.

The light-transmitting plate 218 may include, for example, a transflective region 2181 that allows light emitted from the light-emitting element 217 to pass therethrough and a specular reflection region 2182 that has a higher reflectivity than the transflective region 2181. In the case where the light emitting assembly 217 is turned off, the transflective region 2181 is preferably capable of visually occluding the light emitting assembly 217 and exhibiting a good specular effect together with the specular reflection region 2182. In particular, in the case where the light emitting element 217 is turned off, the visual difference between the transflective area 2181 and the specular reflection area 2182 is smaller, so that the appearance of the front surface of the light transmitting plate 218 has higher uniformity.

Fig. 4 schematically illustrates an inner door 21 according to an exemplary embodiment of the present application.

As shown in fig. 4, the inner door 21 may include an inner door body 211 and a mirror 215, the mirror 215 covering on a front side of the inner door body 211 in a depth direction D corresponding to the first storage space 2101. In this embodiment, the second storage space 2102 is located below the mirror 215. The inner door 21 may also include a second storage unit 216 for cosmetic products, which may be disposed within the second storage space 2102. This arrangement allows the user to conveniently use the cosmetic product and mirror 215 stored in the second storage space 2102. In this case, even if the user opens the outer door 22 for a long time in order to use the cosmetic product and the mirror 215 in the second storage space 2102, it is possible to reduce the loss of cold by keeping the inner door 21 closed.
