Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0077] The refrigerator 100 provided in the embodiment of the utility model can have various implementation forms. Figures 1 to 19 This is an example description of a specific implementation of the refrigerator 100 of the utility model. In this embodiment, the refrigerator 100 includes a cabinet 1, a refrigeration system (not shown), an air supply system (not shown), and a door 2.

[0078] The directions described in the text are based on the direction in which the user faces the refrigerator 100, wherein the left and right sides are distinguished by the direction in which the user faces the refrigerator 100, the side facing the user when the refrigerator 100 is in use is defined as the front side, and the side opposite thereto is defined as the rear side, and the upper and lower sides of the refrigerator 100 when generally working normally are defined to distinguish the up and down.

[0079] like Figure 1 As shown, the box body 1 is used to form the overall appearance of the refrigerator 100. The box body 1 is roughly in the shape of a rectangular parallelepiped frame. The top of the box body 1 and the bottom of the box body 1 are opposite ends. From the top of the box body 1 to the bottom of the box body 1 is the height direction of the box body 1. The left side of the box body 1 and the right side of the box body 1 are opposite sides. From the left side of the box body 1 to the right side of the box body 1 is the width direction of the box body 1. The front side of the box body 1 and the rear side of the box body 1 are opposite sides. From the front side of the box body 1 to the rear side of the box body 1 is the thickness direction of the box body 1. The box body 1 includes an inner liner and a box shell. The inner liner is arranged in the box shell. An installation space is formed between the two, which is used to install other component structures of the refrigerator 100 and form a foam insulation layer. A refrigeration compartment 3 for placing goods is formed inside the inner liner. The refrigeration compartment 3 is provided with a take-in and put-out port, and the take-in and put-out port is arranged toward the front side of the box body 1. The refrigeration compartment 3 can be a refrigeration temperature environment, a freezing temperature environment, or a normal temperature environment. A door body 2 is provided at the access opening. The door body 2 is in a straight plate shape and is arranged at the front side of the box body 1. The door body 2 is connected to the box body 1 in an openable and closable manner to open or close the refrigeration compartment 3.

[0080] The refrigeration system is used to provide cold air to the refrigeration compartment 3; the refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a filter dryer, a return air pipe, a throttling device, and a refrigerant. Each component is distributed at different positions of the cabinet 1 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process, and an evaporation process. The compression process is: after the power cord of the refrigerator 100 is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and then cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a filter dryer to remove moisture and impurities, and then flows into the throttling device, and the throttling and pressure reduction are performed through the throttling device, and the refrigerant becomes a wet vapor at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat to gasify, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the change of the state of the refrigerant, and the heat in the refrigerator 100 is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator 100.

[0081] The air supply system is installed in the box 1 to provide power for the flow of cold air; the air supply system generally includes a fan and an air supply duct defined in the box 1. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box 1 is also defined to form an air duct cavity, which is connected to the air supply duct and the refrigeration chamber 3 respectively, so that the air supply duct is connected to the refrigeration chamber 3 through the air duct cavity; it should be noted that the inner tank is provided with an air outlet, which is used to connect the air duct cavity and the refrigeration chamber 3. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the refrigeration chamber 3 to cool the refrigeration chamber 3. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall of the inner tank opposite to the opening of the refrigeration chamber 3 or on the side wall of the inner tank adjacent to the opening of the refrigeration chamber 3; it should also be noted that the refrigeration system and the air supply system belong to the common knowledge technology in the field and will not be repeated here.

[0082] In the refrigerator 100, reference Figure 1 to Figure 2As an example of this embodiment, there is a refrigeration compartment 3 located at the upper part of the box body 1 and a refrigeration compartment 3 located at the lower part of the box body 1, wherein the refrigeration compartment 3 located at the upper part of the box body 1 and the refrigeration compartment 3 located at the lower part of the box body 1 can generally be divided into a freezer compartment and a refrigerator compartment according to the function and the set temperature of the refrigeration compartment 3, the freezer compartment can be located at the upper part of the box body 1, and can also be located at the lower part of the box body 1, and both the freezer compartment and the refrigerator compartment have a take-in and put-out port.

[0083] According to the refrigeration compartment 3 to which the door body 2 is connected, the door body 2 may include a first door 2a and a second door 2b, wherein, as an example of the present embodiment, the first door 2a is connected to the refrigeration compartment 3 at the lower part of the cabinet 1, and the second door 2b is connected to the refrigeration compartment 3 at the upper part of the cabinet 1, and both the first door 2a and the second door 2b can move relative to the corresponding access opening of the refrigeration compartment 3 to open and close the corresponding refrigeration compartment 3.

[0084] It can be understood that the first door 2a is connected to the refrigeration compartment 3 at the bottom of the box body 1, which is only an example used for illustration of this embodiment. In other embodiments, according to the functions set by the refrigerator 100 and the user's needs for taking and placing items, the first door 2a can also be connected to the refrigeration compartment 3 at the top of the box body 1.

[0085] There are various ways for the door body 2 to move relative to the access opening of the refrigerating compartment 3. For example, the door body 2 can be connected to the refrigerating compartment 3 in a rotational manner to achieve relative movement of the access opening, or can be connected to the refrigerating compartment 3 in a translational manner to achieve relative movement of the access opening. In the case where the door body 2 and the refrigerating compartment 3 are connected in a rotational manner to achieve relative movement of the access opening, the door body 2 can be connected to the box body 1 through a hinge structure, and the user pulls the door body 2 to rotate the door body 2 around the rotation axis defined by the hinge structure, so that the door body 2 is opened or closed in the refrigerating compartment 3. In the case where the door body 2 and the refrigerating compartment 3 are connected in a translational manner to achieve relative movement of the access opening, the door body 2 can be connected to the box body 1 through a guide rail structure, and the user pushes the door body 2 to move the door body 2 along the guide axis defined by the guide rail structure, so that the door body 2 is opened or closed in the refrigerating compartment 3. It is understandable that the way in which the door body 2 moves relative to the refrigeration compartment 3 is not limited to the aforementioned example. Depending on the functions of the refrigerator 100 and the scenarios in which the refrigerator 100 is used, the door body 2 can also adopt other ways of moving relative to the refrigeration compartment 3 to enable the door body 2 to open and close the refrigeration compartment 3.

[0086] refer to Figure 1-2 In this embodiment, the first door 2a is disposed at the lower part of the cabinet 1, and is connected to the cabinet 1 so that the first door 2a can rotate relative to the cabinet 1. When the user pulls the first door 2a, the first door 2a can perform the following actions, so that the refrigeration compartment 3 covered by the first door 2a can be fully opened or fully closed as the first door 2a rotates:

[0087] The first door 2a is closed on the box body 1, and the first door 2a covers the refrigeration compartment 3 at the lower part of the box body 1, so that the refrigeration compartment 3 at the lower part of the box body 1 is completely closed;

[0088] The first door 2a is pulled and rotated by the user, and the first door 2a leaves the cabinet 1 and is away from the access opening of the refrigerating chamber 3 at the lower part of the cabinet 1, so that the refrigerating chamber 3 at the lower part of the cabinet 1 is fully opened.

[0089] refer to Figure 2 The first door 2a is provided with a through hole 4, and the through hole 4 penetrates the first door 2a, so that the area of ​​the refrigeration chamber 3 corresponding to the first door 2a is connected with the outside of the box body 1, so that when the first door 2a is closed on the box body 1, the area of ​​the refrigeration chamber 3 corresponding to the through hole 4 is connected with the outside of the box body 1.

[0090] Based on the through hole 4, the user can place commonly used items in the area corresponding to the through hole 4, so that the user can obtain these commonly used items through the through hole 4, so that the refrigerator 100 of this embodiment can realize multiple application functions, such as:

[0091] In the case where the refrigeration compartment 3 at the bottom of the housing 1 is a refrigerator, the user can place common items such as cooking seasonings and water containers in the area inside the refrigeration compartment 3 corresponding to the through hole 4, so that these items can absorb the cold inside the refrigeration compartment 3. In this way, the user does not need to frequently open the first door 2a to take out and store common items. Compared with the area of ​​the refrigeration compartment 3 at the bottom of the housing 1 connected to the outside of the housing 1 after the first door 2a is opened, the area of ​​the through hole 4 connected to the outside of the housing 1 is smaller when it is opened, thereby reducing the cold loss caused by the user taking out and storing items in the refrigeration compartment 3, thereby saving energy consumption caused by the daily use of the refrigerator 100.

[0092] In the case where the refrigeration compartment 3 at the lower part of the housing 1 is a freezer compartment, the user can place ice-making water in the area inside the refrigeration compartment 3 corresponding to the through hole 4, so that the ice-making water can absorb the cold inside the refrigeration compartment 3 to achieve the purpose of making ice. In this way, the user can quickly take the ice cubes inside the freezer compartment by opening the through hole 4 and enjoy the ice cubes. Moreover, for the environment of the freezer compartment, opening the through hole 4 can more significantly reduce the cold loss caused by the user taking and storing items in the process compared to opening the first door 2a, making the refrigerator 100 more energy-efficient.

[0093] Moreover, through the design of the through hole 4, the user can take out the items in the refrigeration compartment 3 or store the items in the refrigeration compartment 3 without opening the first door 2a, so that the refrigerator 100 can be used in a smaller space, making the refrigerator 100 of this embodiment applicable to more scenarios.

[0094] It can be understood that, with the side of the refrigerator 100 facing the user when in use as the front side and the side opposite thereto as the rear side, when the access opening of the refrigerating compartment 3 is arranged at the front side of the refrigerator 100, the extension path of the through hole 4 is various, but the through hole 4 at least needs to penetrate the first door 2a along the front-to-back direction of the refrigerating compartment 3, so that when the first door 2a is covered with the box body 1, the refrigerating compartment 3 corresponding to the area where the through hole 4 is located is connected with the outside of the box body 1. Therefore, the through hole 4 penetrates the first door 2a in the front-to-back direction of the refrigerating compartment 3, which can be used as another example of this embodiment.

[0095] refer to Figure 1-2 In order to keep the through hole 4 sealed when not opened, the refrigerator 100 of this embodiment is connected with a sub-door 5 at the location of the through hole 4 to seal the through hole 4. The shape of the sub-door 5 can match the shape of the through hole 4, so that the sub-door 5 can be embedded in the through hole 4 to achieve sealing inside the through hole 4; the shape of the sub-door 5 can also be inconsistent with the shape of the through hole 4, so that the sub-door 5 covers the front side of the through hole 4 to achieve sealing outside the through hole 4.

[0096] When the auxiliary door 5 is connected to the through hole 4, the through hole 4 can be sealed by the auxiliary door 5, so that the through hole 4 is closed and in a closed state. When the auxiliary door 5 is separated from the through hole 4, the through hole 4 is immediately opened and in an open state, so that the area of ​​the refrigeration chamber 3 corresponding to the through hole 4 is connected to the outside of the box body 1, and the user can take or store items from the area.

[0097] It should be noted that after the sub-door 5 is separated from the through hole 4, the sub-door 5 is independently separated from the first door 2a, and the sub-door 5 is not connected to the first door 2a, that is, after the sub-door 5 is separated from the through hole 4, there is no connection structure between the sub-door 5 and the first door 2a, and the sub-door 5 can be separated from the first door 2a and move independently, so that the user can take the sub-door 5 to any place outside the refrigerator 100. In this way, the user can also take the sub-door 5 away in a small space, thereby opening the through hole 4, taking out the items in the refrigeration compartment 3 or storing the items in the refrigeration compartment 3. Through the cooperation between the through hole 4 and the sub-door 5, the refrigerator 100 can realize the common functions of taking and storing items in the refrigerator 100 without opening the first door 2a, so that the user can conveniently take out the refrigerated or frozen items in the refrigeration compartment 3.

[0098] It is understandable that the structural design of the first door 2a is various. Figure 1-2 In addition to the structure of the first door 2a shown in the figure, the first door 2a can also be configured with different structures according to the shape and function of the refrigerator 100. The structure of the first door 2a is further described with reference to another example of this embodiment. Figure 7-15 The first door 2a includes a first door shell 20a, a first door liner 21a, and a first foaming layer 22a, wherein:

[0099] The first door housing 20a is located at the front side of the first door 2a and constitutes the outer surface of the first door 2a;

[0100] The first door liner 21a is located at the rear side of the first door 2a, on the side of the first door 2a facing the access opening, and the first door liner 21a is connected to the first door shell 20a, so that the first door liner 21a and the first door shell 20a constitute a foaming cavity of the first door 2a;

[0101] The first foaming layer 22a is filled in the foaming cavity of the first door 2a, so that the interior of the first door 2a is provided with foaming material to ensure the heat preservation effect of the first door 2a.

[0102] The penetration hole 4 is formed from the first door shell 20a to the first door liner 21a, so that the penetration hole 4 can penetrate the first door 2a along the front-to-back direction of the refrigeration compartment 3, thereby connecting the refrigeration compartment 3 with the external space of the cabinet 1. As an example of this embodiment, the first door shell 20a and the first door liner 21a can be preliminarily vacant in the corresponding area during the prefabrication molding stage, and a plate is provided in the area corresponding to the outer peripheral side of the penetration hole 4 to seal the foaming cavity of the first door body 2, so that after the first door shell 20a and the first door liner 21a are connected, the corresponding penetration hole 4 is formed. As another example of this embodiment, the penetration hole 4 can also be obtained by cutting the first door shell 20a and the first door liner 21a. After the first door shell 20a and the first door liner 21a are cut, a seal can be provided in the area corresponding to the outer peripheral side of the penetration hole 4, so that the first foaming layer 22a in the foaming cavity of the first door body 2 is sealed, thereby ensuring the sealing and heat preservation effect of the first door 2a.

[0103] As an example of this embodiment, refer to Fig.10 The auxiliary door 5 includes an auxiliary door body 5a and a handle portion 5b, wherein the auxiliary door body 5a is used to connect to the through hole 4 to seal the through hole 4; the handle portion 5b is connected to the auxiliary door body 5a, and the handle portion 5b is configured to be able to be held, so that the auxiliary door body 5a can be taken out of the through hole 4 and separated from the first door 2a.

[0104] It is understandable that the auxiliary door body 5a is mainly used to seal the through hole 4 so that the cold air in the refrigeration chamber 3 cannot escape from the through hole 4. When a component that can be used to achieve other functions is connected to the auxiliary door body 5a, such as a storage component 9, the auxiliary door body 5a can also achieve other functions accordingly. Fig. 20 , a storage component 9 is connected to the rear side of the sub-door 5 to hold articles; and, when the sub-door 5 is connected to the through hole 4, the storage component 9 at least partially enters the refrigerating compartment 3, so that the articles held therein can absorb the cold inside the refrigerating compartment 3; and the storage component 9 can follow the sub-door 5 to detach from the through hole 4, so that the storage component 9 detaches from the inside of the refrigerating compartment 3 and is no longer connected to the first door 2a.

[0105] The items stored in the storage member 9, the size of the storage member 9, and even the shape and structure of the storage member 9 can be configured and selected according to the function of the refrigerator. For example, the storage member 9 can be used to store water or food, so that the user can place the storage member 9 inside the refrigeration compartment 3 through the sub-door 5, so that the water or food stored in the storage member can absorb the coldness of the refrigeration compartment, thereby quickly preparing cold water or frozen food for the user. Fig. 20 The storage component 9 is provided with a guide nozzle 9a on the side facing the refrigeration compartment 3, that is, the side of the storage component 9 away from the auxiliary door 5, so that Fig. 20 The storage member shown can be suitable for pouring out the water inside the storage member 9 when used to hold water. It should be noted that Fig. 20 The structure of the storage component 9 shown is only used as an example of the present embodiment. As mentioned above, the shape and structure of the storage component 9 can be configured and selected according to the function of the refrigerator.

[0106] Furthermore, based on the connection between the storage component 9 and the sub-door 5, the user can take out the sub-door 5 and the storage component 9 from the refrigerator 100 together by taking out the sub-door 5. Since the storage component 9 and the sub-door 5 can be separated from the refrigerator 100, the storage component 9 can be taken to any position outside the refrigerator 100 to enjoy the cold water or frozen items prepared by the storage component 9. In this way, the application function of the sub-door 5 can be expanded based on the user's usage needs, and is not limited to the sealing penetration hole 4.

[0107] The handle portion 5b is mainly used for the user to hold, so that the user can hold the handle portion 5b and remove the auxiliary door body 5a from the penetration hole 4. The shape and contour of the handle portion 5b can be various, such as the handle portion 5b can be raised from the auxiliary door body 5a, so that a space for the user to hold is formed between the handle portion 5b and the auxiliary door body 5a, or the handle portion 5b can also be embedded in the auxiliary door body 5a, by hollowing out a certain area on the front side of the auxiliary door body 5a, so that the handle portion 5b can be built into the front side of the auxiliary door body 5a, or the handle portion 5b can also be a hole structure formed on the auxiliary door body 5a and connected to the auxiliary door body 5a. When the weight of the auxiliary door body 5a is not large, the user can use the hole set on the auxiliary door body 5a as the handle portion 5b to remove the auxiliary door body 5a from the penetration hole 4.

[0108] Since the auxiliary door 5 is sealed to the through hole 4, the heat preservation effect of the auxiliary door 5 itself will also affect the heat preservation effect of the refrigeration compartment 3. Generally speaking, the auxiliary door 5 can be made of heat preservation material or the interior of the auxiliary door 5 can be filled with heat preservation material. Figure 12-13 The sub-door body 5a includes a second shell 50a, wherein the second shell 50a constitutes the outer surface of the sub-door 5, and a sub-door inner cavity 52a is formed in the second shell 50a, and the sub-door inner cavity 52a is filled with a second foaming layer 51a, so that the sub-door 5 has the ability to keep warm.

[0109] It is understandable that the second shell 50a may be an integrally formed structure or a structure composed of multiple components. Depending on the manufacturing process of the second shell 50a, there may be multiple implementations of the second foaming layer 51a filling the sub-door inner cavity 52a.

[0110] In the refrigerator 100 of this embodiment, after the sub-door 5 is separated from the through hole 4, there is no connection between the sub-door 5 and the first door 2a, so that the sub-door 5 can be separated from the first door 2a independently, so that the sub-door 5 can be taken to the area outside the box body 1 by the user when the first door 2a is still covered with the refrigeration compartment 3. In order to enable the sub-door 5 to be connected to the through hole 4 without an additional connection structure with the first door 2a, as an example of this embodiment, refer to Figure 7-19 , the auxiliary door 5 is embedded in the inside of the through hole 4. The auxiliary door 5 is matched with the outer contour shape of the through hole 4, so that the auxiliary door 5 can be fixed by using the structure of the through hole 4 itself, so that the auxiliary door 5 can be connected to the inside of the through hole 4 without setting up additional connection structures such as hinge structures and guide rail structures between the auxiliary door 5 and the through hole 4.

[0111] According to the thickness of the sub-door 5 and the position of the sub-door 5 embedded in the penetration hole 4, when the sub-door 5 is embedded in the penetration hole 4, the front side of the sub-door body 5a can be flush with the front side of the first door 2a, or the front side of the sub-door body 5a can be recessed in the front side of the first door 2a, or the front side of the sub-door body 5a can be protruded from the front side of the first door 2a. The relative position between the front side of the sub-door body 5a and the front side of the first door 2a can be selected according to the appearance of the refrigerator 100, the application scenario of the refrigerator 100, and the function configured by the sub-door 5.

[0112] It can be understood that, when the auxiliary door 5 is embedded in the through hole 4, the movement path of the auxiliary door 5 relative to the through hole 4 will be constrained by the through hole 4. In this way, when the through hole 4 is extended along the front-to-back direction of the refrigeration compartment 3, the auxiliary door 5 can be translated relative to the through hole 4 along the front-to-back direction of the refrigeration compartment 3 to approach and move away from the through hole 4. In this way, the user holds the auxiliary door 5 and moves along the extension direction of the through hole 4 to make the auxiliary door 5 translate and move out of the through hole 4. The operation is very convenient. Moreover, when the auxiliary door 5 is fixed inside the through hole 4 and the auxiliary door 5 moves relative to the through hole 4, the surface of the auxiliary door 5 in contact with the through hole 4 will not change, and the bottom of the auxiliary door 5 will contact the inner peripheral side of the through hole 4, so that the auxiliary door 5 and the through hole 4 form a surface contact connection.

[0113] Compared with the structure of hinge connection and guide rail connection, the connection and cooperation between the auxiliary door 5 and the through hole 4 based on surface contact can disperse the weight of the auxiliary door 5 to the through hole 4 through the contact surface, so that the auxiliary door 5 can have a higher weight, or connect with a component with a load-bearing function to carry more items. Moreover, the auxiliary door 5 is connected and cooperated with the through hole 4 by being embedded in the through hole 4, which can make the structure of the auxiliary door 5, the first door 2a and even the through hole 4 simple. The auxiliary door 5 and the through hole 4 realize the load-bearing and fixation of the auxiliary door 5 based on their own structure, so that the door body 2 does not need to be additionally provided with too many connecting components. The structure of the door body 2 can form a relatively stable integrated structure to ensure the stability of the application structure of the door body 2, and also avoid the risk of frequent maintenance of the door body 2 due to the provision of too many connecting components.

[0114] It is understandable that the outline shape of the through hole 4 is various, and it can be circular, square, oval, triangular, or other special-shaped structures. When the secondary door 5 is assembled by being embedded in the through hole 4, as an example of this embodiment, the through hole 4 must have at least a bearing surface 4a, and the bearing surface 4a is arranged to be connected to the bottom of the secondary door 5 when the secondary door 5 is embedded in the through hole 4, so that the through hole 4 can support the secondary door 5.

[0115] refer to Figure 7-19, taking the case where the outline of the through hole 4 is a square and the outline of the auxiliary door 5 is also a square as an example, the inner side wall of the through hole 4 at the bottom is the bearing surface 4a for supporting the auxiliary door 5. When the auxiliary door 5 is embedded in the through hole 4, the bottom of the auxiliary door 5 is attached to the bearing surface 4a of the through hole 4, so that the weight of the auxiliary door 5 is borne by the bearing surface 4a of the through hole 4, so that the auxiliary door 5 can be fixed in the through hole 4 and connected to the through hole 4.

[0116] In order to ensure the sealing of the auxiliary door 5 and the through hole 4, the first door 2a may have a sealing surface 23a. The auxiliary door 5 is connected to the sealing surface 23a, so that the refrigeration compartment 3 and the outside of the cabinet 1 cannot be communicated through the through hole 4. As an example of this embodiment, refer to Fig. 9 , the sealing surface 23a of the first door 2a is located in the penetration hole 4 and is arranged toward the front side of the penetration hole 4; and,

[0117] The sealing surface 23a extends along the inner circumference of the through hole 4, and the sealing surface 23a is left empty inside the through hole 4, so that the sealing surface 23a forms a nearly annular structure, and the inside of the through hole 4 remains open, so that after the sub-door 5 is separated from the through hole 4, the area of ​​the refrigeration chamber 3 corresponding to the through hole 4 can be connected to the outside of the cabinet 1.

[0118] The connection position between the auxiliary door 5 and the sealing surface 23a can be located on the outer peripheral side of the auxiliary door 5. For example, the auxiliary door 5 is connected to the inside of the penetration hole 4. At this time, the sealing surface 23a is arranged inside the penetration hole 4, and the auxiliary door 5 is embedded in the penetration hole 4 to the position of the sealing surface 23a, so that the outer peripheral side of the auxiliary door 5 is connected to the sealing surface 23a, thereby forming a seal that isolates the refrigeration chamber 3 from the outside of the box body 1.

[0119] The connection position between the auxiliary door 5 and the sealing surface 23a can also be located on the rear side of the auxiliary door 5. For example, when the auxiliary door 5 is connected to the front side of the penetration hole 4, the sealing surface 23a can be arranged inside the penetration hole 4 and close to the front opening of the penetration hole 4, so that the rear side of the auxiliary door 5 can be attached to the front side of the penetration hole 4 and connected to the sealing surface 23a to form a seal. Alternatively, when the auxiliary door 5 is connected to the inside of the penetration hole 4, the sealing surface 23a can be arranged inside the penetration hole 4, and the auxiliary door 5 is embedded in the penetration hole 4 to the position of the sealing surface 23a, so that the rear side of the auxiliary door 5 is connected to the sealing surface 23a, and the rear side of the auxiliary door 5 is in contact with the sealing surface 23a, thereby forming a seal to seal the penetration hole 4.

[0120] As a component sealed in the through hole 4, the frequency of the sub-door 5 being taken and moved is higher than that of the first door 2a or the second door 2b. Therefore, in order to avoid the sub-door 5 from damaging the first foaming layer 22a of the first door 2a due to long-term use, thereby affecting the heat preservation effect of the first door 2a, as an example of this embodiment, refer to Figure 14-19The first door 2a may further include a mounting member 6, which is connected to the inner circumference of the penetration hole 4, thereby protecting the inner circumference of the penetration hole 4. Even if the mounting member 6 is worn due to the secondary door 5 repeatedly moving back and forth through the penetration hole 4, maintenance personnel can perform maintenance by replacing the mounting member 6 without replacing the first door 2a.

[0121] It is understandable that a mounting hole 6a is provided in the mounting member 6, and the mounting hole 6a is arranged in the same direction as the penetration hole 4 and penetrates the first door 2a, so as to ensure that when the auxiliary door 5 is separated from the penetration hole 4, the area of ​​the refrigeration chamber 3 corresponding to the penetration hole 4 can be communicated with the outside of the cabinet 1. In addition, when the first door 2a has a sealing surface 23a that forms a sealing match with the auxiliary door 5, the sealing surface 23a can be arranged inside the mounting hole 6a, or formed on the mounting member 6, and the sealing surface 23a is left empty inside the mounting hole 6a, so that when the auxiliary door 5 is separated from the penetration hole 4, the area of ​​the refrigeration chamber 3 corresponding to the penetration hole 4 can be communicated with the outside of the cabinet 1.

[0122] In order to facilitate the connection operation between the auxiliary door 5 and the sealing surface 23a and ensure that the auxiliary door 5 can be connected in place, as an example of this embodiment, reference Figure 17-19 A suction piece 7 may be provided on the front side of the sealing surface 23a, and the front side of the suction piece 7 is the suction surface. Furthermore, the rear side of the auxiliary door 5 may be connected to the suction surface so that the auxiliary door 5 and the sealing surface 23a form a seal to isolate the through hole 4 from the outside of the box body 1.

[0123] The adsorbent 7 may be a structure similar to a magnetic attraction member, so that when the auxiliary door 5 is close to the sealing surface 23a, the adsorbent 7 can generate an adsorption force, so that the auxiliary door 5 has a tendency to move to the position where the sealing surface 23a is located, and guides the user to cover the auxiliary door 5 on the sealing surface 23a, thereby forming a seal that isolates the refrigeration chamber 3 from the outside of the cabinet 1. The magnitude of the adsorption force can be configured according to the material and area of ​​the adsorbent 7, so that the user does not need to spend a lot of effort to remove the auxiliary door 5 from the penetration hole 4, and when the auxiliary door 5 is close to the sealing surface 23a at a certain distance, the adsorbent 7 can generate an adsorption force to move the auxiliary door 5 to the position where the sealing surface 23a is located.

[0124] When the secondary door 5 is connected to the through hole 4, the secondary door 5 is generally placed vertically or nearly vertically. Therefore, generally speaking, a member can be arranged on the front side of the secondary door 5 to prevent the secondary door 5 from falling out of the through hole 4 without external force. Figure 18-19 A limiting protrusion 8 is arranged in the penetration hole 4. The limiting protrusion 8 is located in the penetration hole 4 and is arranged at the bottom of the inner wall of the penetration hole 4. Moreover, the limiting protrusion 8 is configured to be connected to the front side of the sub-door 5 when the sub-door 5 is embedded in the penetration hole 4, so as to limit the front side of the sub-door 5 from being separated from the penetration hole 4.

[0125] It is understandable that the height of the limiting protrusion 8, that is, the distance that the limiting protrusion 8 protrudes from the inner wall of the penetration hole 4, can be configured according to the volume of the auxiliary door 5. The limiting protrusion 8 is a guiding structure such as an arc or an inclined surface, which can make it easier for the auxiliary door 5 to escape from the penetration hole 4. In this way, when the limiting protrusion 8 is applied, the user holds the auxiliary door 5 or the handle 5b of the auxiliary door 5, and after the auxiliary door 5 is translated in the penetration hole 4 for a certain distance, the auxiliary door 5 is slightly rotated, so that the auxiliary door 5 can escape from the penetration hole 4.

[0126] It is understandable that the refrigerator 100 may have various implementation forms. In addition to the refrigerator 100 having two refrigeration compartments 3, the refrigerator 100 may also be configured with only one refrigeration compartment 3. Figure 3-4 , as another example of the refrigerator 100 of this embodiment, Figure 3 The refrigerator 100 shown in FIG. Figure 1 The refrigerators shown differ only in that Figure 3 The refrigerator 100 shown has only one refrigeration compartment 3 in the box body 1, realizing the integration of the refrigerator compartment and the freezer compartment. Correspondingly, the door body 2 sealing the refrigeration compartment 3 may only include the first door 2a, which covers the refrigeration compartment 3 of the box body 1, so that when the first door 2a is covered on the box body 1, the refrigeration compartment 3 inside the box body 1 is completely closed, and when the first door 2a leaves the box body 1 and is far away from the access opening of the refrigeration compartment 3, the refrigeration compartment 3 of the box body 1 is immediately fully opened. Figure 3-4 In the refrigerator 100 shown, the connection between the door body 2 and the cabinet body 1 is Figure 1 The refrigerator 100 shown is the same and will not be described again here.

[0127] exist Figure 3-4 In the refrigerator 100 shown, the through hole 4 provided on the first door 2a has the side of the refrigerating chamber 3 provided with the access opening as the front side, and the through hole 4 also penetrates the first door 2a along the front-to-back direction of the refrigerating chamber 3. In this way, when the first door 2a is closed on the box body 1, the refrigerating chamber 3 located inside the box body 1 can be connected with the outside of the box body 1. Figure 3-4 The refrigerator 100 shown is designed as an integrated refrigerator compartment and a freezer compartment. The user can use the refrigeration compartment 3 area corresponding to the through hole 4 to store items, prepare cold water, prepare ice cubes, etc. Figure 3-4 The refrigerator 100 shown can realize more application functions. Figure 3-4 The first door 2a of the refrigerator 100 shown covers the entire refrigeration compartment 3. When the first door 2a of this type of refrigerator 100 is opened to take out items, the cooling loss of the refrigeration compartment 3 will be greater than that of the refrigerator 100 with two refrigeration compartments 3. Therefore, the user can use the through hole 4 to take out items, which can more effectively save the energy consumption of this type of refrigerator 100.

[0128] Generally speaking, Figure 3 The refrigerator 100 shown is a small-capacity refrigerator 100. The refrigeration compartment 3 area corresponding to the through hole 4 can be configured with auxiliary accessories such as shelves, storage boxes, and water storage boxes through layout to match the application of the through hole 4. Figure 1 The refrigerator 100 shown has the same characteristics as Figure 3 The through hole 4 of the refrigerator 100 is connected to a sub-door 5 to achieve sealing and prevent the cold air in the refrigeration compartment 3 from escaping from the through hole 4. Figure 3-4 ,exist Figure 3 In the refrigerator 100 shown, the auxiliary door 5 connected to the position of the penetration hole 4 can seal the penetration hole 4. When the auxiliary door 5 is connected to the penetration hole 4, the penetration hole 4 is immediately sealed by the auxiliary door 5, so that the penetration hole 4 is closed and in a closed state, and the cold air in the refrigeration chamber 3 can be sealed in the box body 1 under the cooperation of the first door 2a and the auxiliary door 5. When the auxiliary door 5 is separated from the penetration hole 4, the penetration hole 4 is immediately opened and in an open state, so that the refrigeration chamber 3 is connected to the outside of the box body 1, and the user can directly take or store items from the area of ​​the refrigeration chamber 3 corresponding to the penetration hole 4. The cooperation design of the auxiliary door 5 and the penetration hole 4 is similar to Figure 1 The refrigerator 100 shown is the same and will not be described again here.

[0129] It is understandable that, in addition to the above-described embodiments, the refrigerator 100 may also be configured with a plurality of refrigeration compartments 3 and a plurality of doors 2. Figure 5-6 , as another example of the refrigerator 100 of this embodiment, Figure 5 The refrigerator 100 shown in FIG. Figure 1 The refrigerators shown differ only in that Figure 5 In the case where the body 1 of the refrigerator 100 shown also has a refrigerating compartment 3 located at the upper part of the body 1 and a refrigerating compartment 3 located at the lower part of the body 1, the door body 2 of the same refrigerating compartment 3 may include a first door 2a and a second door 2b to form a double-door refrigerator 100, wherein the first door 2a and the second door 2b respectively cover a portion of the corresponding refrigerating compartment 3, and generally speaking, the area of ​​the refrigerating compartment 3 covered by the first door 2a is equal to the area of ​​the refrigerating compartment 3 covered by the second door 2b.

[0130] Therefore Figure 5 In the refrigerator 100 shown, when the first door 2a is closed on the cabinet 1, the refrigerating compartment 3 inside the cabinet 1 is only partially closed, and the remaining area of ​​the refrigerating compartment 3 is closed by the second door 2b; and when the first door 2a leaves the cabinet 1 and is far away from the access opening of the refrigerating compartment 3, the refrigerating compartment 3 of the cabinet 1 is only partially opened, and the remaining area of ​​the refrigerating compartment 3 is opened by the second door 2b.

[0131] exist Figure 5In the refrigerator 100 shown, the through hole 4 provided on the first door 2a has the side of the refrigerating chamber 3 provided with the access opening as the front side, and also penetrates the first door 2a along the front-to-back direction of the refrigerating chamber 3. In this way, when the first door 2a is closed on the box body 1, the refrigerator 100 can make the area of ​​the refrigerating chamber 3 located inside the box body 1 corresponding to the through hole 4 communicate with the outside of the box body 1.

[0132] Generally speaking, Figure 5 The refrigerator 100 shown is a large-capacity refrigerator 100, and the refrigeration compartment 3 has a large volume. In this way, the area of ​​the refrigeration compartment 3 corresponding to the through hole 4 can be easily configured with auxiliary accessories such as shelves, storage boxes, and water storage boxes to match the application of the through hole 4. Figure 1 The refrigerator 100 shown has the same characteristics as Figure 5 The through hole 4 of the refrigerator 100 is connected to a sub-door 5 to achieve sealing and prevent the cold air in the refrigeration compartment 3 from escaping from the through hole 4. Figure 1 The refrigerator 100 shown is the same and will not be described again here.

[0133] It should be noted that, in other embodiments, the side-by-side refrigerator 100 may also use two first doors 2a in the same refrigerating compartment 3 as the door body 2 of the refrigerating compartment 3, and the two first doors 2a are respectively provided with respective through-holes 4, so that the refrigerating compartment 3 can form two areas corresponding to the two through-holes 4. In this way, according to the functional areas divided inside the refrigerating compartment 3, the areas corresponding to the through-holes 4 respectively arranged on the two first doors 2a can be used to realize different functions, such as preparing cold water, storing commonly used items, etc. The through-holes 4 arranged on each first door 2a have a structure similar to the through-holes 4 arranged on the first door 2a. Figure 1 The structure shown is the same and is not shown again here.

[0134] In summary, the refrigerator 100 provided by the embodiment of the utility model is provided with a through hole 4 on the first door 2a, so that the first door 2a can have a completely open through hole, which can cooperate to realize the application functions of the refrigerator 100 such as taking water and taking things in the door, and compared with the area of ​​the refrigeration compartment 3 connected with the outside of the box body 1 after the first door 2a is opened, the area of ​​the through hole 4 connected with the outside of the box body 1 in the open state is smaller, thereby reducing the cold loss caused by the user taking and storing items in the refrigeration compartment 3, thereby saving the energy consumption caused by the refrigerator 100 in the daily use process; and, by cooperating with the sub-door 5 that can be detached from the through hole 4, the user can completely remove the sub-door 5 from the through hole 4, so that the user can take the items stored in the refrigeration compartment 3 without opening the first door 2a when the first door 2a is closed in the refrigeration compartment 3, so that the user can more conveniently take the refrigerated or frozen items in the refrigeration compartment 3. Moreover, since the sub-door 5 of the refrigerator 100 can be detached from the through hole 4, when the user opens the through hole 4 to take items, the sub-door 5 does not need to be flipped over or connected to the first door 2a, so that the sub-door 5 will not occupy the space around the refrigerator 100, so that the through hole 4 can be opened in a small area, expanding the application scenarios of the refrigerator 100 and improving the user experience.

[0135] Moreover, the refrigerator 100 of the present application connects the storage component 9 to the rear side of the sub-door 5, so that when the sub-door 5 is connected to the through hole 4, the storage component 9 can at least partially enter the refrigeration compartment 3, so that the items held by the storage component 9 can absorb the cold inside the refrigeration compartment 3 to obtain frozen items, such as ice water, ice cubes, etc., and the storage component 9 of the present application can be separated from the through hole 4 together with the sub-door 5, so that the user can take the storage component 9 out of the refrigeration compartment 3 by taking the sub-door 5. In this way, the user can more conveniently take out the refrigerated or frozen items in the refrigeration compartment 3 without opening the first door 2a.

[0136] Secondly, the refrigerator 100 of the present application embeds the sub-door 5 into the penetration hole 4, and realizes the positioning and fixing of the sub-door 5 by the structure of the penetration hole 4 itself. There is no need to set additional connecting components inside the penetration hole 4 or the first door 2a to fix the sub-door 5. In addition, the refrigerator 100 uses the structural layout of the penetration hole 4 penetrating the first door 2a, so that the sub-door 5 can move inside the penetration hole 4 in a translational manner relative to the penetration hole 4 based on the guiding effect of the structure of the penetration hole 4 itself. There is no need to set additional power components inside the penetration hole 4 or the first door 2a to drive the sub-door 5 to move. As a result, the structure of the door body 2 of the refrigerator 100 can be kept simple, the application structure of the door body 2 is stable, and frequent maintenance of the door body 2 can be avoided.
