TECHNICAL FIELD

[0003] The present application relates to the technical field of electrical equipment, in particular to a refrigerator and refrigeration equipment. BACKGROUND

[0004] A refrigerator is a kind of household electrical appliance commonly used in people's daily life. The refrigerator generally comprises a cabinet and a door body, wherein the cabinet is internally formed with a refrigeration compartment for placing articles to be frozen or refrigerated, and the door body is opened to the refrigeration compartment to open or seal the refrigeration compartment. The area of the door body of the refrigerator is generally larger than the opening area of the refrigeration compartment, so as to facilitate the user to access the articles, facilitate the disassembly and cleaning of the refrigerator, and the door body of some refrigerators is further provided with a storage compartment configured to freeze or refrigerate articles, so as to improve the use function of the refrigerator.

[0005] However, when the user uses the refrigerator, the user generally needs to open the door body to take the articles from the refrigeration compartment, so that the use experience of the user is relatively single. Moreover, when the user takes the articles commonly used in the refrigeration compartment, the user often needs to frequently open the door body to open the refrigeration compartment, so that the loss of cold quantity in the refrigeration compartment is relatively obvious, and the compressor needs to frequently operate, thereby increasing the energy consumption of the refrigerator.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0102] The refrigerator 100 provided by the embodiments of the present application can have various implementation forms. The directions described below are based on the direction that the user faces the refrigerator 100, wherein the left side and the right side are distinguished from each other in the direction that the user faces the refrigerator 100, the side of the refrigerator 100 facing the user when the refrigerator 100 is used is defined as the front side, and the side opposite to it is defined as the back side, and the upper side and the lower side of the refrigerator 100 when the refrigerator 100 is generally normally working are defined to distinguish the upper and lower sides.

[0103] As shown in FIG. 1 and FIG. 2, in some embodiments, the refrigerator 100 comprises a cabinet 1. The cabinet 1 is configured to form the overall appearance of the refrigerator 100. The cabinet 1 is generally in the shape of a cuboid frame. The top of the cabinet 1 and the bottom of the cabinet 1 are opposite ends. The height direction of the cabinet 1 is from the top of the cabinet 1 to the bottom of the cabinet 1. The left side of the cabinet 1 and the right side of the cabinet 1 are opposite sides. The width direction of the cabinet 1 is from the left side of the cabinet 1 to the right side of the cabinet 1. The front side of the cabinet 1 and the back side of the cabinet 1 are opposite sides. The thickness direction of the cabinet 1 is from the front side of the cabinet 1 to the back side of the cabinet 1. The cabinet 1 comprises an inner container and a cabinet shell. The inner container is arranged in the cabinet shell. The inner container and the cabinet shell form a mounting space therebetween. The mounting space is configured to mount other components of the refrigerator 100 and form a foamed insulation layer. The inside of the inner container forms a refrigeration compartment 3 configured to place goods. The refrigeration compartment 3 is provided with a taking and placing opening. The taking and placing opening is arranged in the direction of the front side of the cabinet 1. The refrigeration compartment 3 can be a cold storage temperature environment, a refrigeration temperature environment, or a normal temperature environment.

[0104] As shown in FIG. 1 and FIG. 2, in some embodiments, the refrigerator 100 comprises a door body 2. The door body 2 is arranged at the taking and placing opening. The door body 2 is arranged in the shape of a straight plate at the front side of the cabinet 1. The door body 2 is connected to the cabinet 1 in a hinged manner. The door body 2 is configured to open or close the refrigeration compartment 3.

[0105] In some embodiments, the refrigerator 100 further comprises a refrigeration system configured to provide cold air to the refrigeration compartment 3. The refrigeration system generally refers to a closed system composed of a compressor, an evaporator, a condenser, a drying filter, 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 functions. 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 as follows. After the power cord of the refrigerator 100 is plugged in and the contacts of the temperature controller are connected, the compressor starts to work. The low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor. After being compressed into high-temperature and high-pressure refrigerant gas by the compressor, it is discharged to the condenser. The condensation process is as follows. The high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser. The temperature drops, and the refrigerant is gradually cooled into saturated vapor at room temperature and high pressure, and then into saturated liquid. The throttling process is as follows. After the condensed refrigerant saturated liquid is filtered to remove water and impurities by the drying filter, it flows into the throttling device. The throttling device is used for throttling and pressure reduction. The refrigerant becomes wet steam at room temperature and low pressure. The evaporation process is as follows. The wet steam at room temperature and low pressure enters the evaporator. The wet steam starts to absorb heat and vaporize. The temperature of the evaporator and its surrounding environment is lowered. The refrigeration is achieved. Moreover, the refrigerant becomes low-temperature and low-pressure gas. The refrigerant from the evaporator returns to the compressor. The above process is repeated. Through the state change of the refrigerant, energy conversion is realized. The heat in the refrigerator 100 is transferred to the air outside the cabinet. Thus, the refrigeration cycle of the refrigerator 100 is achieved.

[0106] In some embodiments, the refrigerator 100 further comprises an air supply system. The air supply system is installed in the cabinet 1 and is configured to provide power for the cold air flow. The air supply system generally comprises a fan and an air supply air duct defined in the cabinet 1. In some embodiments, the air inlet end of the air supply air duct is arranged close to the fan, and the air outlet end of the air supply air duct is arranged away from the fan. In other embodiments, the air outlet end of the air supply air duct is arranged close to the fan, and the air inlet end of the air supply air duct is arranged away from the fan. The cabinet 1 further defines an air duct cavity in communication with the air supply air duct and the refrigeration compartment 3, respectively, so that the air supply air duct is in communication with the refrigeration compartment 3 through the air duct cavity; it should be noted that the inner container is provided with an air outlet, which is configured to communicate the air duct cavity and the refrigeration compartment 3, and the cold air generated by the refrigeration system is introduced into the air duct cavity through the air supply air duct by the operation of the fan, and flows to the refrigeration compartment 3 through the air outlet to refrigerate the refrigeration compartment 3. It should be further noted that in some embodiments, the air outlet is arranged on the side wall of the inner container opposite to the opening of the refrigeration compartment 3 or on the side wall adjacent to the opening of the refrigeration compartment 3.

[0107] Referring to FIGS. 1 and 2, the above-mentioned refrigerator 100 has a refrigeration compartment 3 located at the upper portion of the cabinet 1 and a refrigeration compartment 3 located at the lower portion of the cabinet 1. According to the function and set temperature of the refrigeration compartment 3, the refrigeration compartment 3 located at the upper portion of the cabinet 1 and the refrigeration compartment 3 located at the lower portion of the cabinet 1 can generally be divided into a freezing compartment and a refrigerating compartment. The freezing compartment can be located at the upper portion of the cabinet 1 or at the lower portion of the cabinet 1, and both the freezing compartment and the refrigerating compartment have a taking and placing opening.

[0108] The door body 2 can include a first door 2a and a second door 2b. As an example of the present embodiment, the first door 2a is connected to the refrigeration compartment 3 at the lower portion of the cabinet 1, and the second door 2b is connected to the refrigeration compartment 3 at the upper portion of the cabinet 1. The first door 2a and the second door 2b can both move relative to the taking and placing opening of the corresponding refrigeration compartment 3 to open or close the corresponding refrigeration compartment 3.

[0109] It can be understood that the first door 2a is connected to the refrigeration compartment 3 at the lower portion of the cabinet 1, which is only an example for illustration in the present embodiment. In other embodiments, according to the function provided by the refrigerator 100 and the user's demand for taking and placing articles, the first door 2a can also be connected to the refrigeration compartment 3 at the upper portion of the cabinet 1.

[0110] The door body 2 can be connected to the cabinet 1 through a hinge structure, and a user can pull the door body 2 to rotate the door body 2 about an axis of rotation defined by the hinge structure, so as to open or close the refrigeration compartment 3. In the case where the door body 2 is connected to the cabinet 1 through a guide rail structure, a user can push the door body 2 to move the door body 2 along a guide axis defined by the guide rail structure, so as to open or close the refrigeration compartment 3. It can be understood that the manner in which the door body 2 moves relative to the refrigeration compartment 3 is not limited to the manners described above, and the door body 2 can also adopt other manners of moving relative to the refrigeration compartment 3 to open or close the refrigeration compartment 3, according to the functions provided by the refrigerator 100 and the application scenarios of the refrigerator 100.

[0111] Referring to FIGS. 1 and 2, the first door 2a of the present embodiment is arranged at the lower portion of the cabinet 1, and the first door 2a is connected to the cabinet 1 so that the first door 2a can rotate relative to the cabinet 1. With the first door 2a pulled by a user, the first door 2a can perform an action such that the refrigeration compartment 3 covered by the first door 2a can be fully opened or closed with the action of the first door 2a rotating. The first door 2a is closed to the cabinet 1, and the first door 2a covers the refrigeration compartment 3 at the lower portion of the cabinet 1, so that the refrigeration compartment 3 at the lower portion of the cabinet 1 is fully closed. The first door 2a is rotated by being pulled by a user, and the first door 2a is away from the cabinet 1 and away from the access to the refrigeration compartment 3 at the lower portion of the cabinet 1, so that the refrigeration compartment 3 at the lower portion of the cabinet 1 is fully opened.

[0112] Referring to FIG. 2, the first door 2a is provided with a through hole 4. The through hole 4 penetrates the first door 2a, so that the region of the refrigeration compartment 3 corresponding to the first door 2a is in communication with the outside of the cabinet 1, so that when the first door 2a is closed to the cabinet 1, the region of the refrigeration compartment 3 corresponding to the through hole 4 is in communication with the outside of the cabinet 1.

[0113] Since the first door 2a is provided with the through hole 4, a user can place commonly used items in the region 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 the present embodiment can realize various application functions.

[0114] For example, in the case that the lower refrigeration compartment 3 of the cabinet 1 is a refrigeration compartment, the user can place commonly used items such as cooking spices, containers filled with water, etc. 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 can take and store commonly used items without frequently opening the first door 2a. Compared with the area of the lower refrigeration compartment 3 of the cabinet 1 communicating with the outside of the cabinet 1 after the first door 2a is opened, the area of the through hole 4 communicating with the outside of the cabinet 1 in the open state is smaller, thereby reducing the loss of cold caused by the user taking and storing items in the refrigeration compartment 3, and saving the energy consumption of the refrigerator 100 in daily use.

[0115] In the case that the lower refrigeration compartment 3 of the cabinet 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 these ice-making water can absorb the cold inside the refrigeration compartment 3 to achieve ice-making. In this way, the user can quickly take ice blocks located inside the freezer compartment by opening the through hole 4, and enjoy the ice blocks. Moreover, compared with opening the first door 2a, opening the through hole 4 can more obviously reduce the loss of cold caused by the user taking and storing items, so that the refrigerator 100 is more energy-saving.

[0116] Moreover, through the design of the through hole 4, the user can take or store items in the refrigeration compartment 3 without opening the first door 2a, so that the refrigerator 100 can be used in a smaller space, and the refrigerator 100 of the embodiment can be applied to more scenes.

[0117] It can be understood that the side of the refrigerator 100 facing the user when in use is the front side, and the opposite side is the back side. When the access opening of the refrigeration compartment 3 is arranged on 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-back direction of the refrigeration compartment 3, so that the first door 2a communicates the area of the refrigeration compartment 3 corresponding to the through hole 4 with the outside of the cabinet 1 when covering the cabinet 1. Therefore, the through hole 4 penetrating the first door 2a along the front-back direction of the refrigeration compartment 3 can be another example of the embodiment.

[0118] Referring to FIG. 1 and FIG. 2, in order to enable the through hole 4 to remain sealed when not opened, the refrigerator 100 of the embodiment is provided with a secondary door 5 at the position of the through hole 4 to seal the through hole 4. The shape of the secondary door 5 can match the shape of the through hole 4, so that the secondary door 5 can be embedded into the through hole 4 to seal the through hole 4 inside the through hole 4. The shape of the secondary door 5 can also be inconsistent with the shape of the through hole 4, in which case the secondary door 5 covers the front side of the through hole 4 to seal the through hole 4 outside the through hole 4.

[0119] When the sub-door 5 is installed in the penetration hole 4, the penetration hole 4 can be closed by the sub-door 5, in a closed state. When the sub-door 5 is detached from the penetration hole 4, the penetration hole 4 is immediately opened, in an open state. At this time, the area of the refrigeration compartment 3 corresponding to the penetration hole 4 is in communication with the outside of the cabinet 1, and the user can take or store items from this area.

[0120] It should be noted that after the sub-door 5 is detached from the penetration hole 4, the sub-door 5 is independently separated from the first door 2a. The sub-door 5 is separated from the first door 2a, that is, after the sub-door 5 is detached from the penetration hole 4, there is no connecting structure between the sub-door 5 and the first door 2a, and the sub-door 5 can be independently moved away from the first door 2a, 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 penetration hole 4 to take or store items in the refrigeration compartment 3. Through the cooperation of the penetration hole 4 and the sub-door 5, the refrigerator 100 can have the functions of taking and storing items as common in refrigerators 100 without opening the first door 2a, so that the user can conveniently take items refrigerated or frozen in the refrigeration compartment 3.

[0121] It can be understood that the structure of the first door 2a is diverse. In addition to the structure of the first door 2a shown in FIGS. 1 and 2, 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 will be further described below with another example of the present embodiment. Referring to FIGS. 6 and 11, the first door 2a includes a first door shell 20a, a first door liner 21a, and a first foaming layer 22a. The first door shell 20a is located at the front side of the first door 2a and constitutes the outer surface of the first door 2a. The first door liner 21a is located at the rear side of the first door 2a, that is, the side of the first door 2a facing the taking and storing 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 the foaming cavity of the first door 2a. 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.

[0122] In some embodiments, the first foaming layer 22a is fixed to the front side of the first door liner 21a, that is, the side facing the first door shell 20a, and the first door liner 21a and the first door shell 20a are abutted to place the first foaming layer 22a between the first door liner 21a and the first door shell 20a.

[0123] In some embodiments, the first foaming layer 22a is fixed to the rear side of the first door shell 20a, that is, the side facing the first door liner 21a, and the first door shell 20a and the first door liner 21a are abutted to place the first foaming layer 22a between the first door shell 20a and the first door liner 21a.

[0124] 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-rear direction of the refrigeration compartment 3, thereby connecting the refrigeration compartment 3 and the external space of the cabinet 1. As an example of the present embodiment, the first door shell 20a and the first door liner 21a can be pre-emptively hollowed in the corresponding regions in the pre-molding stage, and a plate member is arranged in the corresponding region on the outer circumferential side of the penetration hole 4 to seal the foaming cavity of the first door body 2, so that the corresponding penetration hole 4 is formed after the first door shell 20a and the first door liner 21a are connected. As another example of the present embodiment, the penetration hole 4 can also be obtained by cutting the first door shell 20a and the first door liner 21a, and the first door shell 20a and the first door liner 21a are cut, and a seal is arranged in the corresponding region on the outer circumferential side of the penetration hole 4 to seal the first foaming layer 22a in the foaming cavity of the first door body 2, thereby ensuring the sealing and heat-insulating effect of the first door 2a.

[0125] As an example of the present embodiment, referring to FIGS. 9 and 10, the auxiliary door 5 includes an auxiliary door body 5a and a handle portion 5b. The auxiliary door body 5a is configured to be connected to the penetration hole 4 to seal the penetration hole 4. The handle portion 5b is connected to the auxiliary door body 5a. The handle portion 5b is configured to be held and to enable the auxiliary door body 5a to be taken out of the penetration hole 4 and separated from the first door 2a.

[0126] It can be understood that the auxiliary door body 5a is configured to seal the penetration hole 4 so that the cold air in the refrigeration compartment 3 cannot escape from the penetration hole 4. When the auxiliary door body 5a is connected to a component configured to achieve other functions, the auxiliary door body 5a can also achieve other functions accordingly. Referring to FIG. 20, the rear side of the auxiliary door 5 is connected to a storage component 9 to store articles. When the auxiliary door 5 is installed in the penetration hole 4, the storage component 9 at least partially enters the refrigeration compartment 3, so that the stored articles can absorb the cold of the interior of the refrigeration compartment 3. The storage component 9 can be separated from the penetration hole 4 along with the auxiliary door 5, so that the storage component 9 is separated from the interior of the refrigeration compartment 3 and separated from the first door 2a.

[0127] The volume of the storage member 9, the shape of the storage member 9, or the items stored in the storage member 9 can be configured according to the function of the refrigerator. In some embodiments, the storage member 9 is configured to store water. When the user places the storage member 9 inside the refrigeration compartment 3 through the sub-door 5, the water in the storage member 9 can absorb the cold of the refrigeration compartment 3 to form cold water, thereby facilitating the user to drink cold water. In some embodiments, the storage member 9 is configured to store food, such as cooking spices, bread, boxed milk, etc. When the user places the storage member 9 inside the refrigeration compartment 3 through the sub-door 5, the food stored in the storage member 9 can absorb the cold of the refrigeration compartment 3 to facilitate the user to take the food while preserving the freshness of the food. Referring to FIG. 20, the storage member 9 is provided with a flow guide nozzle 9a on the side of the storage member 9 facing the refrigeration compartment 3, i.e., the side of the storage member 9 away from the sub-door 5, so that the storage member shown in FIG. 20 is suitable for pouring out the water inside the storage member 9 when the storage member 9 is configured to store water. It should be noted that the structure of the storage member 9 shown in FIG. 20 is only one example of the present embodiment, and as mentioned above, the shape of the storage member 9 can be configured according to the function of the refrigerator.

[0128] Based on the connection and cooperation between the storage member 9 and the sub-door 5, the user can take out the sub-door 5 together with the storage member 9 connected to the sub-door 5 by taking out the sub-door 5. Since the storage member 9 and the sub-door 5 can be separated from the refrigerator 100, the storage member 9 can be taken to any position outside the refrigerator 100 to enjoy the cold water or frozen items prepared by the storage member 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 sealing the penetration hole 4.

[0129] The handle portion 5b is configured to be gripped by a user, and enables the user to remove the sub-door body 5a from the penetration hole 4 by gripping the handle portion 5b. The shape profile of the handle portion 5b can be various, for example, the handle portion 5b can protrude from the sub-door body 5a, so that a space for the user to grip is formed between the handle portion 5b and the sub-door body 5a. The handle portion 5b protruding from the sub-door body 5a facilitates the user to remove the sub-door body 5a from the penetration hole 4 by the protruding handle portion 5b. Alternatively, the handle portion 5b can also be embedded in the interior of the sub-door body 5a, and a certain area is hollowed out on the front side of the sub-door body 5a, so that the handle portion 5b can be embedded on the front side of the sub-door body 5a. The handle portion 5b embedded in the interior of the sub-door body 5a reduces the thickness and volume of the sub-door 5. Alternatively, the handle portion 5b can also be a hole structure formed on the sub-door body 5a and connected with the sub-door body 5a. When the weight of the sub-door body 5a is not large, the user can use the hole provided on the sub-door body 5a as the handle portion 5b to remove the sub-door body 5a from the penetration hole 4. Using the hole on the sub-door body 5a as the handle portion 5b enables the sub-door 5 to have a simple structure while the sub-door body 5a is removed from the penetration hole 4 by the handle portion 5b.

[0130] Since the sub-door 5 is sealed to the penetration hole 4, the heat preservation effect of the sub-door 5 itself also affects the heat preservation effect of the refrigeration compartment 3. Generally, the sub-door 5 can be made of a heat preservation material or the interior of the sub-door 5 is filled with a heat preservation material. As an example of the present embodiment, referring to FIGS. 12 and 13, the sub-door body 5a includes a second shell 50a which constitutes the outer surface of the sub-door 5. A sub-door cavity 52a is formed in the second shell 50a, and a second foaming layer 51a is filled in the sub-door cavity 52a, so that the sub-door 5 has the ability of heat preservation.

[0131] It can be understood that the second shell 50a can be a one-piece structure or a structure composed of multiple components. Depending on the process for preparing the second shell 50a, the second foaming layer 51a filled in the sub-door cavity 52a can also have various implementation manners.

[0132] In the refrigerator 100 of the present embodiment, after the sub-door 5 is detached from the penetration hole 4, the sub-door 5 is separated from the first door 2a, so that the sub-door 5 can be independently separated from the first door 2a, thereby enabling the sub-door 5 to be taken by the user to the area outside the cabinet 1 while the first door 2a remains closed to the refrigeration compartment 3. In order to enable the sub-door 5 to be connected to the penetration hole 4 without additional connecting structure with the first door 2a, as an example of the present embodiment, referring to FIGS. 7-9, the sub-door 5 is embedded into the interior of the penetration hole 4. By the cooperation of the outer contour shape of the sub-door 5 and the penetration hole 4, the sub-door 5 can be fixed by the structure of the penetration hole 4 itself, so that the sub-door 5 can be connected to the interior of the penetration hole 4 without additional connecting structure such as a hinge structure, a guide rail structure, etc. between the sub-door 5 and the penetration hole 4.

[0133] According to the thickness of the sub-door 5 and the position of the sub-door 5 embedded into the penetration hole 4, when the sub-door 5 is embedded into 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 to reduce the thickness of the door body 2. Alternatively, the front side of the sub-door body 5a can be recessed from the front side of the first door 2a to save the material used for the entire door body 2. Alternatively, the front side of the sub-door body 5a can be protruded from the front side of the first door 2a to facilitate the user's operation on the sub-door body 5a. It can be understood that 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 shape of the refrigerator 100, the application scenario of the refrigerator 100, and the function of the sub-door 5.

[0134] It can be understood that when the sub-door 5 is embedded into the penetration hole 4, the movement path of the sub-door 5 relative to the penetration hole 4 is constrained by the penetration hole 4. Therefore, when the penetration hole 4 is arranged extending along the front-rear direction of the refrigeration compartment 3, the sub-door 5 can be translated relative to the penetration hole 4 along the front-rear direction of the refrigeration compartment 3 to approach and move away from the penetration hole 4. Therefore, the user can hold the sub-door 5 and move along the extension direction of the penetration hole 4 to translate the sub-door 5 out of the penetration hole 4, which is very convenient. Moreover, when the sub-door 5 is fixed inside the penetration hole 4 and the sub-door 5 moves relative to the penetration hole 4, the surface of the sub-door 5 in contact with the penetration hole 4 does not change, and the bottom of the sub-door 5 is in contact with the inner circumferential side of the penetration hole 4, so that the sub-door 5 and the penetration hole 4 form a surface contact connection.

[0135] Compared with the structure of hinge connection and guide rail connection, the connection and cooperation of the sub-door 5 and the through hole 4 based on surface contact can disperse the weight of the sub-door 5 to the through hole 4 through the contact surface, so that the sub-door 5 can have higher weight, or connect with a component having a bearing function to bear more articles. Moreover, the connection and cooperation of the sub-door 5 and the through hole 4 is realized by embedding the sub-door 5 into the through hole 4, which can make the structure of the sub-door 5, the first door 2a and even the through hole 4 simple, and the sub-door 5 and the through hole 4 realize the bearing and fixing of the sub-door 5 based on their own structures, so that the door body 2 does not need to be additionally provided with too many connecting components, and the structure of the door body 2 can form a relatively stable integrated structure to ensure the stable application structure of the door body 2, and also avoid the risk that the door body 2 is easily frequently maintained due to too many connecting components.

[0136] It can be understood that the contour shape of the through hole 4 is various, which can be circular, square, oval, triangular or other special-shaped structures. When the sub-door 5 is assembled by embedding into the through hole 4, as an example of the embodiment, the first door 2a needs to have at least a bearing surface 4a located in the through hole 4, and the bearing surface 4a is arranged to be supported at the bottom of the sub-door 5 when the sub-door 5 is embedded into the inside of the through hole 4, so that the bearing surface 4a can support the sub-door 5.

[0137] Referring to FIGS. 7-9, taking the contour shape of the through hole 4 as square and the contour shape of the sub-door 5 as square as an example, the inner side wall of the through hole 4 at the bottom is the bearing surface 4a configured to support the sub-door 5. When the sub-door 5 is embedded into the inside of the through hole 4, the bottom of the sub-door 5 is fitted to the bearing surface 4a of the through hole 4, so that the weight of the sub-door 5 is received by the bearing surface 4a of the through hole 4, so that the sub-door 5 can be fixed in the inside of the through hole 4 to realize the connection with the through hole 4.

[0138] In order to ensure the sealing performance of the sub-door 5 and the through hole 4, the first door 2a can have a sealing surface 23a. The sub-door 5 is connected to the sealing surface 23a, so that the refrigeration compartment 3 and the outside of the cabinet 1 cannot communicate through the through hole 4. As an example of the embodiment, referring to FIG. 9, the sealing surface 23a of the first door 2a is located in the through hole 4 and arranged towards the front side of the through hole 4. The sealing surface 23a extends along the inner circumferential side of the through hole 4, and the sealing surface 23a is left empty in the inside of the through hole 4, so that the sealing surface 23a forms a structure similar to a ring. 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 compartment 3 corresponding to the through hole 4 can communicate with the outside of the cabinet 1.

[0139] The connecting position between the sub-door 5 and the sealing surface 23a can be located at the outer circumferential side of the sub-door 5, for example, the sub-door 5 is connected to the inside of the penetration hole 4. At this time, the sealing surface 23a is arranged at the inside of the penetration hole 4, and the sub-door 5 is embedded into the penetration hole 4 to the position where the sealing surface 23a is located, so that the outer circumferential side of the sub-door 5 is connected with the sealing surface 23a, thereby forming a seal to isolate the refrigeration compartment 3 from the outside of the cabinet 1.

[0140] The connecting position between the sub-door 5 and the sealing surface 23a can also be located at the rear side of the sub-door 5. For example, when the sub-door 5 is connected to the front side of the penetration hole 4, the sealing surface 23a can be arranged at the inside of the penetration hole 4 and close to the position where the front side of the penetration hole 4 is open, so that the rear side of the sub-door 5 can be connected with the sealing surface 23a when the rear side of the sub-door 5 is attached to the front side of the penetration hole 4, thereby forming a seal. Alternatively, when the sub-door 5 is connected to the inside of the penetration hole 4, the sealing surface 23a can be arranged at the inside of the penetration hole 4, and the sub-door 5 is embedded into the penetration hole 4 to the position where the sealing surface 23a is located, so that the rear side of the sub-door 5 is connected with the sealing surface 23a, and the rear side of the sub-door 5 is in surface contact with the sealing surface 23a, thereby forming a seal to seal the penetration hole 4.

[0141] The sub-door 5 as a component sealed to the penetration hole 4 is taken and moved more frequently than the first door 2a or the second door 2b. Therefore, in order to avoid the first door 2a from being damaged by long-term use of the sub-door 5, thereby affecting the heat preservation effect of the first door 2a, as an example of the present embodiment, referring to FIG. 14 and FIG. 15, the first door 2a can further include a mounting component 6 mounted to the inner circumferential side of the penetration hole 4, thereby forming protection to the inner circumferential side of the penetration hole 4. Even if the mounting component 6 is worn out due to the repeated use of the sub-door 5 in the penetration hole 4, maintenance personnel can repair by replacing the mounting component 6, without the need to replace the first door 2a.

[0142] It can be understood that the mounting component 6 is provided with a mounting hole 6a coaxially arranged with the penetration hole 4 and penetrating through the first door 2a, so as to ensure that when the sub-door 5 is separated from the penetration hole 4, the area of the refrigeration compartment 3 corresponding to the penetration hole 4 can be in communication with the outside of the cabinet 1. Moreover, when the first door 2a has a sealing surface 23a forming a sealing fit with the sub-door 5, the sealing surface 23a can be arranged at the inside of the mounting hole 6a or formed on the mounting component 6, and the sealing surface 23a is left empty at the inside of the mounting hole 6a, so that when the sub-door 5 is separated from the penetration hole 4, the area of the refrigeration compartment 3 corresponding to the penetration hole 4 can be in communication with the outside of the cabinet 1.

[0143] In order to facilitate the connecting operation of the sub-door 5 and the sealing surface 23a and ensure that the sub-door 5 can be connected in place, as an example of the present embodiment, referring to FIGS. 16-19, the front side of the sealing surface 23a can be provided with a suction accessory 7, and the front side of the suction accessory 7 is a suction surface. The rear side of the sub-door 5 can be connected to the suction surface, so that the sub-door 5 forms a seal with the sealing surface 23a to isolate the penetration hole 4 from the outside of the cabinet 1.

[0144] The suction accessory 7 can be a structure similar to a magnetic suction member. In this way, when the sub-door 5 is close to the sealing surface 23a, the suction accessory 7 can generate a suction force, so that the sub-door 5 has a tendency to move to the position of the sealing surface 23a, guiding the user to close the sub-door 5 on the sealing surface 23a, thereby forming a seal to isolate the refrigeration compartment 3 from the outside of the cabinet 1. The size of the suction force can be configured according to the material and area of the suction accessory 7, so that the user does not need to exert too much force to remove the sub-door 5 from the penetration hole 4, and the suction accessory 7 can generate a suction force when the sub-door 5 approaches a certain distance from the sealing surface 23a, causing the sub-door 5 to move to the position of the sealing surface 23a.

[0145] During the connection of the sub-door 5 to the penetration hole 4, the sub-door 5 is generally placed vertically or close to vertical. Therefore, in general, the front side of the sub-door 5 can be provided with a component that prevents the sub-door 5 from being removed from the penetration hole 4 without external force. As an example of the present embodiment, referring to FIGS. 18 and 19, a limiting portion 8 is provided in the penetration hole 4, the limiting portion 8 is located in the penetration hole 4 and is provided at the bottom of the inner side wall of the penetration hole 4, and when the sub-door 5 is inserted into the inside of the penetration hole 4, the limiting portion 8 abuts against the front side of the sub-door 5 to prevent the front side of the sub-door 5 from being removed from the penetration hole 4.

[0146] It can be understood that the height of the limiting portion 8, i.e., the distance by which the limiting portion 8 protrudes from the inner side wall of the penetration hole 4, can be configured according to the size of the volume of the sub-door 5. The limiting portion 8 is an arc-shaped or beveled guide structure that can make it easier for the sub-door 5 to be removed from the penetration hole 4. In this way, when the limiting portion 8 is applied, the user holds the sub-door 5 or the handle portion 5b of the sub-door 5 and translates the sub-door 5 in the penetration hole 4 by a certain distance, and then slightly rotates the sub-door 5 to make the sub-door 5 removed from the penetration hole 4.

[0147] It can be understood that the refrigerator 100 can have various embodiments, in addition to the aforementioned refrigerator 100 provided with two refrigeration compartments 3, the refrigerator 100 can also be configured with only one refrigeration compartment 3. Referring to FIGS. 3 and 4, as another example of the refrigerator 100 of the present embodiment, the refrigerator 100 shown in FIG. 3 is different from the refrigerator shown in FIG. 1 only in that the cabinet 1 of the refrigerator 100 shown in FIG. 3 has only one refrigeration compartment 3, realizing the integration of the refrigeration compartment and the freezing compartment. Correspondingly, the door body 2 sealing the refrigeration compartment 3 can only include the first door 2a, the first door 2a covers the refrigeration compartment 3 of the cabinet 1, so that when the first door 2a is closed on the cabinet 1, the refrigeration compartment 3 inside the cabinet 1 is completely closed, and when the first door 2a is away from the cabinet 1 and away from the access opening of the refrigeration compartment 3, the refrigeration compartment 3 of the cabinet 1 is immediately opened. In the refrigerator 100 shown in FIGS. 3 and 4, the connection of the door body 2 and the cabinet 1 is the same as that of the refrigerator 100 shown in FIG. 1, which will not be described here.

[0148] In the refrigerator 100 shown in FIGS. 3 and 4, the penetration hole 4 provided on the first door 2a is on the side of the refrigeration compartment 3 provided with the access opening, which is the front side. The penetration hole 4 also penetrates the first door 2a along the front-rear direction of the refrigeration compartment 3. In this way, the refrigerator 100 can make the refrigeration compartment 3 located inside the cabinet 1 communicate with the outside of the cabinet 1 when the first door 2a is closed on the cabinet 1. Based on the design of the refrigerator 100 shown in FIGS. 3 and 4, which integrates the refrigeration compartment and the freezing compartment, the user can use the area of the refrigeration compartment 3 corresponding to the penetration hole 4 to store items, prepare cold water, and prepare ice cubes, so that the refrigerator 100 shown in FIGS. 3 and 4 can realize more application functions. Moreover, since the first door 2a of the refrigerator 100 shown in FIGS. 3 and 4 covers the entire refrigeration compartment 3, the loss of cold energy of the refrigeration compartment 3 when the first door 2a is opened to take items will be greater than that of the refrigerator 100 with two refrigeration compartments 3. Therefore, the user can more effectively save the energy consumption of this type of refrigerator 100 by using the penetration hole 4 to take items.

[0149] Generally speaking, the refrigerator 100 shown in FIG. 3 is a small-capacity refrigerator, and the area of the refrigerating compartment 3 corresponding to the through hole 4 can be configured with shelves, storage boxes, water storage boxes and other auxiliary accessories through layout, to cooperate with the application of the through hole 4. The same as the refrigerator 100 shown in FIG. 1, the through hole 4 of the refrigerator 100 shown in FIG. 3 is connected with a sub-door 5 to realize sealing and prevent the cold air in the refrigerating compartment 3 from escaping from the through hole 4. Referring to FIGS. 3 and 4, in the refrigerator 100 shown in FIG. 3, the sub-door 5 connected at the position of the through hole 4 can seal the through hole 4. When the sub-door 5 is connected to the through hole 4, the through hole 4 is immediately sealed by the sub-door 5, so that the through hole 4 is closed and in a closed state, and the cold air in the refrigerating compartment 3 can be sealed in the cabinet 1 under the cooperation of the first door 2a and the sub-door 5. When the sub-door 5 is separated from the through hole 4, the through hole 4 is immediately opened and in an open state, so that the refrigerating compartment 3 is in communication with the outside of the cabinet 1, and the user can directly take or store articles from the area of the refrigerating compartment 3 corresponding to the through hole 4. The cooperation design of the sub-door 5 and the through hole 4 is the same as that of the refrigerator 100 shown in FIG. 1, which will not be described here.

[0150] It can be understood that, in addition to the implementation forms described above, the refrigerator 100 can also be configured with multiple refrigerating compartments 3 and multiple door bodies 2. Referring to FIGS. 5 and 6, as another example of the refrigerator 100 of the present embodiment, the refrigerator 100 shown in FIG. 5 is different from the refrigerator shown in FIG. 1 in that the cabinet 1 of the refrigerator 100 shown in FIG. 5, when having the refrigerating compartment 3 located at the upper part of the cabinet 1 and the refrigerating compartment 3 located at the lower part of the cabinet 1, the door body 2 of the same refrigerating compartment 3 can include a first door 2a and a second door 2b, forming a side-by-side door refrigerator 100. The first door 2a and the second door 2b respectively cover part of the area of the corresponding refrigerating compartment 3. 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.

[0151] Therefore, in the refrigerator 100 shown in FIG. 5, when the first door 2a covers 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. When the first door 2a is away from the cabinet 1 and 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.

[0152] In the refrigerator 100 shown in FIG. 5, the through hole 4 provided on the first door 2a is provided on the side of the refrigerating compartment 3 where the access opening is located, as the front side, and penetrates the first door 2a along the front-rear direction of the refrigerating compartment 3. In this way, the refrigerator 100 can make the area of the refrigerating compartment 3 inside the cabinet 1 corresponding to the through hole 4 communicate with the outside of the cabinet 1 when the first door 2a covers the cabinet 1.

[0153] Generally speaking, the refrigerator 100 shown in FIG. 5 is a large-capacity refrigerator 100, and the refrigeration compartment 3 has a larger volume. In this way, the area of the refrigeration compartment 3 corresponding to the penetration hole 4 can more easily be configured with shelves, storage boxes, water storage boxes, and other auxiliary accessories, in cooperation with the application of the penetration hole 4. As with the refrigerator 100 shown in FIG. 1, the penetration hole 4 of the refrigerator 100 shown in FIG. 5 is connected with a secondary door 5 to achieve sealing and prevent cold air in the refrigeration compartment 3 from escaping from the penetration hole 4. The cooperative design of the secondary door 5 and the penetration hole 4 is the same as that of the refrigerator 100 shown in FIG. 1, and will not be described again here.

[0154] It should be noted that in other embodiments, two first doors 2a can also be applied in the same refrigeration compartment 3 of the open-door refrigerator 100 as the door body 2 of the refrigeration compartment 3, and the two first doors 2a respectively have their own penetration hole 4 design, so that the refrigeration compartment 3 can form two areas respectively corresponding to the two penetration holes 4. In this way, according to the functional areas divided inside the refrigeration compartment 3, the areas corresponding to the penetration holes 4 respectively provided on the two first doors 2a can be respectively configured to achieve different functions, such as preparing cold water, storing frequently used items, etc. The penetration hole 4 structure provided on each first door 2a is the same as that shown in FIG. 1, and will not be shown here.

[0155] In summary, the refrigerator 100 provided by the embodiments of the present application sets the penetration hole 4 on the first door 2a, so that the first door 2a can have a completely open through hole, which can cooperate to achieve application functions of the refrigerator 100 such as in-door water taking and in-door item taking. Moreover, compared with the area of the refrigeration compartment 3 and the outside of the cabinet 1 connected after the first door 2a is opened, the area of the penetration hole 4 and the outside of the cabinet 1 connected in the open state is smaller, thereby reducing the loss of cold energy caused by the user taking and storing items in the refrigeration compartment 3, and further saving the energy consumption of the refrigerator 100 in the daily use process. Moreover, by cooperating with the secondary door 5 that can be separated from the penetration hole 4, the user can completely remove the secondary door 5 from the penetration 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 to the refrigeration compartment 3, and the user can more conveniently take the items refrigerated or frozen in the refrigeration compartment 3. Moreover, since the secondary door 5 of the refrigerator 100 can be separated from the penetration hole 4, when the user opens the penetration hole 4 to take the items, the secondary door 5 does not need to be flipped and does not need to be connected with the first door 2a, so that the secondary door 5 does not occupy the space around the refrigerator 100, thereby enabling the penetration hole 4 to be opened in a small area, expanding the application scenarios of the refrigerator 100, and improving the user experience.

[0156] Moreover, the refrigerator 100 of the present application is capable of making the storage member 9 at least partially enter the refrigeration compartment 3 when the sub-door 5 is connected to the through hole 4, so that the articles contained in the storage member 9 can absorb the cold energy inside the refrigeration compartment 3 to obtain frozen articles such as ice water, ice cubes, etc. In addition, the storage member 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 out the storage member 9 from the refrigeration compartment 3 by taking the sub-door 5. In this way, the user can more conveniently take the articles refrigerated or frozen in the refrigeration compartment 3 without opening the first door 2a.

[0157] Secondly, the refrigerator 100 of the present application is capable of positioning and fixing the sub-door 5 by embedding the sub-door 5 into the through hole 4, so that the through hole 4 itself can realize the positioning and fixing of the sub-door 5 without the need of additional connecting components to fix the sub-door 5 inside the through hole 4 or the first door 2a. In addition, the refrigerator 100 utilizes the structure layout of the through hole 4 penetrating the first door 2a, so that the sub-door 5 can move in the translational mode relative to the through hole 4 based on the guiding effect of the structure of the through hole 4 inside the through hole 4, without the need of additional power components to drive the sub-door 5 to move. In summary, the structure of the door body 2 of the refrigerator 100 can be kept simple, and the application structure of the door body 2 is stable, avoiding frequent maintenance of the door body 2.

[0158] In order to enable the user to take and place the articles in the refrigeration compartment without opening the door body, the present application further provides a refrigeration device.

The refrigeration cycle process includes a series of processes involving compression, condensation, expansion and evaporation, and realizes the refrigeration of the articles in the cabinet 1.

[0161] First, low-temperature, low-pressure refrigerant gas enters the compressor, which compresses the low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser to be condensed. In the condenser, the refrigerant is condensed into a liquid phase, and heat is released to the surrounding environment through the condensation process under the action of the cooling fan.

[0162] The expansion valve expands the high-temperature, high-pressure liquid-phase refrigerant condensed in the condenser into low-temperature, low-pressure liquid-phase refrigerant. The low-temperature, low-pressure liquid-phase refrigerant enters the evaporator, where the refrigerant expanded in the expansion valve is evaporated, and the refrigerant gas in a low-temperature, low-pressure state is returned to the compressor. The evaporator can cool the gaseous environment in the cabinet 1 by utilizing the latent heat of evaporation of the refrigerant.

[0163] Referring to FIGS. 21 to 23, the refrigeration device further comprises a door body 2 connected to the cabinet 1 and capable of rotating relative to the cabinet 1 to open or close the refrigeration compartment 3, the door body 2 being provided with a mounting portion 20 penetrating the door body 2 along the thickness direction of the door body 2.

[0170] The connection structure between the accommodation component 200 and the door body 2 ensures the sealing connection between the accommodation component 200 and the door body 2, thereby avoiding the leakage of cold air due to the loose fit between the accommodation component 200 and the door body 2, and ensuring the refrigeration effect of the refrigeration compartment 3.

[0171] In some embodiments, the refrigeration device further includes a water kettle 300 which is detachably arranged in the accommodation portion. The water kettle 300 is arranged to be detachably arranged in the accommodation portion, so that the water kettle 300 can be taken out of or placed into the accommodation component 200 according to actual use requirements. The accommodation component 200 has a first opening portion 213 located at the front side of the accommodation component 200, which is configured to put the water kettle, so as to facilitate the taking and placing of the water kettle 300 from the accommodation component 200.

[0172] By arranging the mounting portion 20 extending to the refrigeration compartment 3 on the door body 2 and arranging the accommodation component 200 configured to place the water kettle 300 at the mounting portion 20, the water kettle 300 is mounted on the door body 2, and the mounting position of the water kettle 300 is shifted from the inside of the refrigeration compartment 3 to the door body 2. Therefore, when the user takes the water kettle 300, the user only needs to take the water kettle 300 from the door body 2, without the need to frequently open and close the door body 2 to take the water kettle 300 from the refrigeration compartment 3, which is simple and convenient.

[0173] When the kettle 300 is placed in the accommodating part, it is at least partially located in the refrigeration compartment 3 to absorb the cold in the refrigeration compartment 3.

The water outlet 311 is a water outlet formed on one side of the kettle 300, which facilitates the user to pour out the chilled water.

[0176] The kettle 300 further includes a kettle front panel 38 connected to the front side of the kettle body 34, and the kettle front panel 38 is accommodated in the first accommodating part.

[0177] The kettle body 34 is accommodated in the second accommodating part. The kettle body 34 and the kettle front panel 38 form a kettle accommodating cavity, and a handle 36 is provided on the kettle front panel 38. The handle 36 arranged at the kettle front panel 38 can facilitate the taking operation of the kettle 300. The handle 36 is embedded in the kettle front panel 38, which can realize the embedded arrangement of the handle 36 and reduce the volume of the kettle 300.

[0178] In some embodiments, the front side of the kettle front panel 38 is formed with an embedded part 381 recessed to the side of the kettle accommodating cavity, and the handle 36 is assembled in the embedded part 381, and the highest point of the handle 36 is slightly higher than or flush with the front side. The kettle front panel 38 protrudes to the side of the kettle accommodating cavity, so that the embedded part 381 is formed at the front side of the kettle front panel 38, and the embedded part 381 can be used to realize the embedded installation of the handle 36. The handle 36 is arranged with the highest point slightly higher than or flush with the front side, which realizes the embedded hidden arrangement of the handle 36, reduces the thickness of the entire kettle 300, and reduces the volume of the kettle 300.

[0179] In some embodiments, the top of the kettle front panel member 38 forms a water inlet nozzle 33.

[0181] When water is injected into the kettle 300 receiving cavity through the water inlet portion, the water flow will flow downward along the water flow guide channel 39, and then flow out through the water flow guide outlet portion 311. After the water flow hits the water flow guide portion 37, the water flow will flow downward along the arc-shaped guide surface of the water flow guide portion 37, buffering the impact force of the water flow falling, reducing the height of the water flow splashing, effectively reducing the splashing phenomenon, and reducing the water injection noise.

[0182] In some embodiments, the water flow guide outlet portion 311 is arranged opposite to the top end of the water flow guide portion 37. In this way, while ensuring that the water flow from the water flow guide outlet portion 311 flows downward along the arc-shaped guide surface of the water flow guide portion 37, it is also beneficial to reduce the size of the water inlet nozzle 33 in the width direction, thereby making the structure of the kettle 300 more compact when having the same liquid capacity, and further facilitating the reduction of the thickness of the door body 2.

[0183] In some embodiments, referring to FIGS. 32-34, a water flow guide main pipe segment is formed on the kettle front panel member 38, arranged at the periphery of the water inlet portion and extending downward from the water inlet portion. The bottom of the water flow guide main pipe segment is connected to an inclined water flow guide segment, which is configured to change the direction of the water flow outlet to guide the water flow to the water flow guide outlet portion 311, so that the water flow splashing onto the water flow guide outlet portion 311 can flow downward to the water flow guide portion 37.

[0184] In some embodiments, referring to FIG. 26, the accommodating portion includes a first accommodating portion 210 formed at the side of the accommodating member 200 close to the door front shell 21, configured to accommodate the kettle front panel member 38, and the shape thereof is adapted to the shape of the kettle front panel member 38.

In some embodiments, the sealing member 26 further comprises two second sealing portions respectively connected to the two ends of the first sealing portion and arranged at the positions of the side barrier portions 212 and extending at least partially into the through portion 211. The first sealing portion and the second sealing portions can be integrally formed.

[0195] The barrier portion 212 is structured in a three-side baffle structure mode constituted by the top barrier portion 212 and the side barrier portions 212 arranged at the two sides of the top barrier portion 212, and no baffle is arranged at the bottom position. In this way, the kettle 300 can be conveniently arranged to abut against the bottom of the first accommodating portion 210 for pulling and taking the kettle 300, and the kettle 300 is convenient to take and place.

[0196] In some embodiments, the first accommodating portion 210 further comprises a side plate constituting portion on which a clamping portion 510 is formed. The two sides of the kettle front panel member 38 are formed with clamping portions 520 corresponding to the clamping portion 510.

[0197] When the kettle 300 is arranged in the accommodating portion, the clamping portion 520 is clamped in the clamping portion 510 to position the kettle 300, and the cooperation of the clamping portion 510 and the clamping portion 520 can realize positioning of the kettle 300 after being placed in place, avoiding falling of the kettle 300.

[0198] To facilitate taking of the kettle 300, the clamping portion 520 is arranged as a semispherical protrusion, and the clamping portion 510 is arranged as a clamping groove matched with the shape, that is, the positioning of the two can be ensured, and the kettle 300 can be taken out without resistance.

[0199] In some embodiments, the first accommodating portion 210 is formed with a position guiding portion 230 near the bottom side of the first opening portion 213, and the position guiding portion 230 protrudes from the bottom surface of the first accommodating portion 210. The position guiding portion 230 has a guiding surface.

[0214] First, low-temperature, low-pressure refrigerant gas enters the compressor, and the compressor compresses the low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser for condensation. In the condenser, the refrigerant condenses into a liquid phase, and under the action of a heat dissipation fan, heat is released to the surrounding environment through the condensation process.

[0215] The expansion valve expands the high-temperature, high-pressure liquid-phase refrigerant formed in the condenser into low-temperature, low-pressure liquid-phase refrigerant.
