Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, a freezer has a refrigeration compartment inside, which creates a refrigerated environment for storing goods.

[0003] In recent years, as people spend more time outdoors, they want to be able to easily move some of the food and drinks from their refrigerators to other locations for easy access during picnics, camping, or family gatherings. Currently, it's possible to install detachable portable insulated boxes on refrigerators, allowing users to remove them for use during outdoor activities.

[0004] However, when portable insulated boxes are installed on refrigerators, the sealed insulation layer on the outside of the boxes makes it inconvenient for users to store and retrieve refrigerated items. This also takes up some of the refrigerator's cooling space and greatly affects the user experience. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigeration device in which the insulated box can be taken out and used separately from the refrigeration device, or it can be conveniently used inside the refrigeration device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a refrigeration device, including a housing forming an outer shell of the refrigeration device; a liner disposed within the housing, the liner having a refrigeration chamber; and an insulated box movably disposed within the refrigeration chamber, the insulated box comprising: an insulated shell movably disposed within the refrigeration chamber, the insulated shell having an insulated cavity; a drawer movably disposed within the insulated shell, at least a portion of the drawer's sidewall exposed outside the insulated shell; and a locking assembly disposed on the sidewall of the drawer exposed outside the insulated shell; wherein the sidewall of the insulated shell has a locking groove arranged opposite to the locking assembly; the locking assembly has a first state and a second state cooperating with the locking groove; in the first state, the locking assembly engages with the locking groove, the drawer is locked within the insulated shell, allowing the drawer and the insulated shell to be removed together from the refrigeration chamber; in the second state, the locking assembly disengages from the locking groove, allowing the drawer to move relative to the insulated shell, and allowing the drawer to be removed individually from the refrigeration chamber.

[0008] The above technical solution has the following advantages or beneficial effects: By movably placing the insulation shell inside the refrigeration room, and movably placing the drawer assembly inside the insulation shell, and by providing a locking groove on the side wall of the insulation shell opposite to the locking assembly, the locking assembly has a first state and a second state of engaging with the locking groove. Users can easily switch the connection state between the drawer assembly and the insulation shell by controlling the engagement state of the locking assembly and the locking groove. Specifically, when the locking assembly is in the first state, the locking assembly locks and connects the insulation shell and the drawer assembly to form an integral structure, allowing the user to remove the entire insulated box from the refrigeration room for outdoor activities or other scenarios requiring mobile refrigeration. When the locking assembly is in the second state, the locking assembly unlocks the insulation shell and the drawer assembly, making them detachable, allowing the drawer assembly to be used independently. In daily use of the refrigeration unit, users can independently remove the drawer unit as a storage drawer for the refrigeration unit, while the insulation shell remains inside the refrigeration room. This allows the drawer unit of the insulation box to also be used as a refrigeration space for the refrigeration unit, which not only avoids the problem of the insulation box occupying space when installed in the refrigeration room, but also improves the user's operational convenience by allowing the drawer unit to be removed separately.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein the refrigeration chamber has a front opening, and the heat-insulating shell is movable along the front-rear direction of the refrigeration chamber and can be taken out of the refrigeration chamber through the front opening.

[0010] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by setting a front opening in the refrigeration chamber, the insulation shell can be moved along the front and back direction of the refrigeration chamber and taken out through the front opening. Users only need to perform simple push and pull operations in front of the refrigeration chamber to easily complete the taking and putting of the insulation shell, which greatly reduces the difficulty and complexity of operation.

[0011] In some embodiments of this application, a refrigeration device is provided, wherein the front side wall of the insulation shell is provided with a box opening, and the box opening and the front opening of the refrigeration chamber are located on the same side of the refrigeration chamber.

[0012] Another technical solution described above has the following advantages or beneficial effects: Taking a refrigerator as an example, the refrigeration compartment has a front opening, and the insulation shell can be moved along the front-to-back direction of the refrigeration compartment and removed through this front opening. Users only need to perform a simple push-pull operation in front of the refrigeration compartment to easily remove and place the insulation shell, greatly reducing the difficulty and complexity of operation. Furthermore, the drawers inside the insulation box can be removed or installed in the box in the same direction of movement as other drawers inside the refrigerator, allowing the drawers of the insulation box to be used as storage space within the refrigerator, thus fully utilizing the installation space of the insulation box as storage space.

[0013] In some embodiments of this application, a refrigeration device is provided, wherein the front side wall of the drawer component is provided with a drawer cover, the drawer cover being used to close or open the box opening; when the drawer cover is closed on the front side of the box opening, the lock assembly is arranged opposite to the lock groove.

[0014] Another technical solution described above has the following advantages or beneficial effects: When the drawer cover is closed in front of the box opening, the locking assembly and the locking groove are arranged opposite each other. The user can easily switch between the first and second states of the locking assembly and the locking groove when the drawer cover is closed, thereby achieving locking and unlocking between the drawer and the insulation shell, making the drawer locking operation simpler and more direct. This avoids problems such as incomplete locking or structural interference caused by incorrect drawer positioning or an unclosed opening during locking operations, improving the directness of the locking assembly's operation.

[0015] In some embodiments of this application, a refrigeration device is provided, wherein a latch is provided on the front side wall of the insulation shell; a plug-in hole is provided on the back side of the drawer cover; a plug-in cavity is provided inside the drawer cover, and the plug-in cavity communicates with the plug-in hole; a locking assembly is movably disposed on one side of the plug-in cavity; when the drawer cover is closed at the box opening, the plug-in hole and the latch are arranged opposite to each other, the latch can extend through the plug-in hole and be disposed in the plug-in cavity, and the locking assembly can extend into the plug-in cavity and engage with the locking groove.

[0016] Another technical solution described above has the following advantages or beneficial effects: During the process of inserting the drawer component into the insulation cavity through the box opening, because the insertion hole and the latch are arranged opposite each other, as the drawer component moves towards the interior of the insulation cavity, the latch can be inserted into the insertion cavity through the insertion hole. This simplifies the locking state between the drawer component and the insulation shell. Specifically, the user only needs to close the drawer cover at the box opening, and the latch will automatically align with the insertion hole and the insertion cavity. Then, moving the locking assembly will engage with the lock groove and complete the locking. Furthermore, the latch's deep insertion cavity, which cooperates with the locking assembly, provides structural protection for the engagement between the locking assembly and the latch. Simultaneously, it fully utilizes the internal space of the drawer cover, making the internal structure of the insulation box and refrigeration unit more compact, thereby improving space utilization.

[0017] In some embodiments of this application, a refrigeration device is provided. The lock assembly includes a rotating member rotatably disposed on the side wall of the drawer cover and located on one side of the insertion cavity; a latch, one end of which is fixed to the rotating member; the rotating member has a first direction and a second direction, the first direction being opposite to the second direction; when the rotating member rotates in the first direction, the rotating member can drive the other end of the latch to extend into the insertion cavity to engage with the lock groove; when the rotating member rotates in the second direction, the rotating member can drive the other end of the latch to leave the insertion cavity to separate from the lock groove.

[0018] Another technical solution described above has the following advantages or beneficial effects: by arranging the rotating component on one side of the insertion cavity, the locking tongue connected to the rotating component can engage with the latch in the insertion cavity as the rotating component rotates. Specifically, when the rotating component rotates in the first direction, the locking tongue engages with the lock groove under the action of the rotating component, thereby connecting the drawer cover to the insulation shell, that is, locking the drawer component to the insulation shell. When the rotating component rotates in the second direction, the locking tongue separates from the lock groove under the action of the rotating component, thereby allowing the drawer component to move freely inside the insulation box and to be removed from the insulation box independently.

[0019] In some embodiments of this application, a refrigeration device is provided, wherein the heat-insulating shell includes a heat-insulating outer shell, which is movably disposed in the refrigeration chamber; an inner liner disposed inside the heat-insulating outer shell, and a heat-insulating interlayer is formed between the inner liner and the heat-insulating outer shell; and a plurality of heat-insulating boards, which are disposed within the heat-insulating interlayer.

[0020] Another technical solution described above has the following advantages or beneficial effects: An insulation interlayer is formed between the insulation outer shell and the inner liner. Multiple insulation boards are placed within the insulation interlayer to form a heat insulation barrier, thereby providing insulation for the items inside the insulation cavity and effectively reducing cold loss. Furthermore, by setting insulation boards within the insulation interlayer, compared to the current structure using an integral foam insulation layer, the insulation boards used in this application allow for a reduction in the thickness of the insulation layer while maintaining the same insulation effect, thus increasing the usable storage space inside the insulated box.

[0021] In some embodiments of this application, a refrigeration device is provided, wherein the refrigeration chamber is provided with an air supply nozzle for delivering cold air; the outer wall of the insulation shell is provided with a first communication port, which is arranged opposite to the air supply nozzle; the insulation shell is provided with a first sealing plate, which is movably disposed at the first communication port and is used to close or open the first communication port; when the insulation shell is installed in the refrigeration chamber, the air supply nozzle can extend into the first communication port and push open the first sealing plate, so that the air supply nozzle extends into the insulation cavity, and the air supply nozzle communicates with the insulation cavity.

[0022] Another technical solution described above has the following advantages or beneficial effects: By movably installing a first sealing plate inside the insulation shell, the first sealing plate can automatically open the first communication port according to the installation status between the insulation shell and the refrigeration unit housing. When the insulation shell is not installed in the refrigeration room, the first sealing plate closes the first communication port, effectively preventing the cold air in the insulation cavity from leaking into the external environment; when the insulation shell is installed in the refrigeration room, the air nozzle opens the first sealing plate to deliver cold air. In this way, without the need for complex operation or settings by the user, the insulation cavity can be cooled by the air nozzle simply by installing the insulation box inside the housing.

[0023] In some embodiments of this application, a refrigeration device is provided, wherein the refrigeration chamber is provided with a return air nozzle for delivering cold air; the outer wall of the insulation shell is provided with a second communication port, which is arranged opposite to the return air nozzle; a second sealing plate is provided inside the insulation shell, which is movably disposed at the second communication port and is used to close or open the second communication port; when the insulation shell is installed in the refrigeration chamber, the return air nozzle can extend into the second communication port and push open the second sealing plate, so that the return air nozzle extends into the insulation cavity, and the return air nozzle communicates with the insulation cavity.

[0024] Another technical solution described above has the following advantages or beneficial effects: By movably installing a second sealing plate inside the insulation shell, the second sealing plate can automatically open the second connection port according to the installation status between the insulation shell and the refrigeration unit housing. When the insulation shell is not installed in the refrigeration room, the second sealing plate closes the second connection port, effectively preventing the cold air in the insulation cavity from leaking into the external environment; when the insulation shell is installed in the refrigeration room, the return air nozzle opens the second sealing plate to achieve cold air delivery. In this way, without the need for complex operation or settings by the user, the airflow in the insulation cavity can be circulated to the outside through the return air nozzle simply by installing the insulation box inside the housing.

[0025] In some embodiments of this application, a refrigeration device is provided, wherein a first sealing plate is rotatably disposed on the peripheral edge of the first communication port; the insulation shell is further provided with a first reset member, one end of the first reset member being connected to the inner wall of the insulation shell, and the other end of the first reset member being connected to the first sealing plate, the first reset member being capable of driving the first sealing plate to rotate toward the first communication port to close the first communication port; a second sealing plate is rotatably disposed on the peripheral edge of the second communication port; the insulation shell is further provided with a second reset member, one end of the second reset member being connected to the inner wall of the insulation shell, and the other end of the second reset member being connected to the second sealing plate, the second reset member being capable of driving the second sealing plate to rotate toward the second communication port to close the second communication port.

[0026] Another technical solution described above has the following advantages or beneficial effects: By setting a first resetting member connected between the first sealing plate and the insulation shell, when the insulation shell is removed from the refrigeration chamber, the first sealing plate is no longer subjected to the thrust from the air supply nozzle. The first resetting member can drive the first sealing plate to automatically reset and tightly close the first connection port. Simultaneously, by setting a second resetting member connected between the second sealing plate and the insulation shell, when the insulation shell is removed from the refrigeration chamber, the second sealing plate is no longer subjected to the thrust from the return air nozzle. The second resetting member can drive the second sealing plate to automatically reset and tightly close the second connection port, thereby achieving automatic opening and closing of the second sealing plate. This not only improves the operational convenience of the insulation box but also effectively prevents cold air from leaking from the insulation cavity into the external environment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] The refrigeration device in the embodiments of the present invention can be a refrigeration cabinet such as a freezer or refrigerator.

[0053] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0054] like Figure 1 As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigerator. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0055] In some embodiments, the enclosure 1 may include a refrigeration compartment 101. There may be multiple refrigeration compartments 101, which can serve as independent storage spaces, such as freezers, refrigerators, and variable-temperature compartments, to meet different refrigeration needs (freezing, refrigeration, and variable-temperature) depending on the type of food, and to store items requiring refrigeration or freezing. The multiple refrigeration compartments 101 may be arranged vertically or horizontally.

[0056] Figure 2 for Figure 1 A partial schematic diagram. It should be noted that... Figure 2 for Figure 1 A schematic diagram of the structure behind the concealed enclosure.

[0057] like Figure 2 As shown, the refrigeration device may include a liner 11. The liner 11 may be located inside the housing 1. The liner 11 may contain a refrigeration compartment 101.

[0058] like Figure 1 As shown, in some embodiments, the refrigeration device includes a door 13. The door 13 is disposed above the housing 1 and covers the opening of the refrigeration compartment 101 for opening and closing the refrigeration compartment 101 with the upper opening.

[0059] It should be noted that multiple doors 13 can be installed. Each door 13 can be installed in a one-to-one correspondence with a refrigeration room 101. Multiple doors 13 can open and close a single refrigeration room 101 simultaneously. A single door 13 can also open and close multiple refrigeration rooms 101 simultaneously.

[0060] In some embodiments, the refrigeration system may include a compressor (not shown). The compressor, as the power source of the refrigeration cycle, draws in low-temperature, low-pressure refrigerant gas and compresses it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0061] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser receives refrigerant flowing from the compressor, cools the high-temperature, high-pressure refrigerant gas from the compressor, and converts it into a liquid state. The condenser transfers heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0062] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0063] In some embodiments, the refrigeration system may include an evaporator (not shown). A throttling device delivers a throttled and depressurized refrigerant into the evaporator. The evaporator is used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0064] In some embodiments, the compressor, condenser, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0065] Figure 3 for Figure 2 An exploded view; Figure 4 for Figure 3 Another exploded view;

[0066] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigeration device may include an insulated box 2. The insulated box 2 can be movably disposed within the refrigeration chamber 101. The insulated box 2 can be installed within the refrigeration chamber 101, thereby utilizing the refrigeration performance of the refrigeration system within the refrigeration device to maintain a low-temperature environment within the insulated box 2. Furthermore, since the insulated box 2 is movably disposed within the refrigeration chamber 101, when the user removes the insulated box 2 from the refrigeration chamber 101, the insulated box 2 can serve as a separate insulated space, convenient for use during outdoor picnics, camping, or other outdoor activities.

[0067] like Figure 4 As shown, in some embodiments, the insulation box 2 may include an insulation shell 21. The insulation shell 21 is movably disposed within the refrigeration chamber 101. An insulation cavity 201 is provided inside the insulation shell 21.

[0068] The insulation shell 21 can have insulation properties, which can keep the items placed in the insulation cavity 201 warm. After the insulation box 2 is taken out of the refrigeration room 101, the insulation shell 21 can continue to keep the items in the drawer 22 warm, extending the low-temperature storage time of the items in the outdoor environment.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments, the insulated box 2 may include a drawer 22. The drawer 22 is movably disposed within the insulated housing 21. At least a portion of the sidewalls of the drawer 22 are exposed outside the insulated housing 21.

[0070] The drawer 22 is provided inside the insulated box 2 and can be movably disposed within the insulated shell 21, making it more convenient for users to use. Moreover, at least a portion of the sidewall of the drawer 22 is exposed outside the insulated shell 21, allowing users to operate the drawer 22 through the exposed portion, such as opening or closing the drawer 22, thereby easily storing and retrieving the refrigerated items inside the drawer 22.

[0071] Furthermore, since the drawer component 22 is movably disposed within the insulation shell 21, when the entire insulation box 2 is installed in the refrigeration chamber 101, the user can directly move the drawer component 22 separately to take out items from the drawer or put items into the drawer component 22. Even if the insulation box 2 is installed in the refrigeration chamber 101, the user can separate the drawer component 22 from the insulation shell 21 and use it directly as a drawer of the refrigeration device, thereby improving the space utilization rate of the refrigeration device.

[0072] Figure 5 for Figure 2 A schematic diagram of the first state; Figure 6 for Figure 2 A schematic diagram of the second state.

[0073] like Figure 5 and Figure 6 As shown, in some embodiments, the insulated box 2 may include a locking assembly 23. The locking assembly 23 is located on the drawer 22 exposed on the side wall of the insulated housing 21, which facilitates user operation. When the user needs to lock or unlock the drawer 22, the operation can be performed directly on the side wall without complicated disassembly or searching for a specific location, thus improving the efficiency and convenience of operation.

[0074] The side wall of the thermal insulation shell 21 is provided with a lock groove 202 arranged opposite to the lock assembly 23. The lock assembly 23 has a first state and a second state that cooperate with the lock groove 202.

[0075] like Figure 5 As shown, in the first state, the lock assembly 23 engages with the lock groove 202, and the drawer piece 22 is locked inside the insulation shell 21, so that the drawer piece 22 and the insulation shell 21 can be taken out of the refrigeration compartment 101 together.

[0076] like Figure 6 As shown, in the second state, the locking assembly 23 is separated from the locking groove 202, allowing the drawer piece 22 to move relative to the insulation housing 21 and allowing the drawer piece 22 to be removed individually from the cooling compartment 101.

[0077] The locking groove 202 is provided on the side wall of the insulation shell 21, which provides a cooperating component for the locking assembly 23, enabling the locking assembly 23 to switch between the first state and the second state, thereby realizing the locking and separation functions of the drawer 22 and the insulation shell 21.

[0078] Specifically, such as Figure 5 As shown, the first state is when the drawer assembly 22 is locked to the insulation shell 21. In this state, the locking assembly 23 engages with the locking groove 202, and the drawer assembly 22 is locked inside the insulation shell 21. At this time, the insulation shell 21 and the drawer assembly 22 form a whole, and the user can remove the entire insulated box 2 (including the insulation shell 21 and the drawer assembly 22) from the refrigeration compartment 101 for outdoor activities or other scenarios requiring mobile refrigeration. This facilitates the removal of the entire insulated box 2, making it convenient for users to transfer refrigerated items between different locations. Furthermore, due to the presence of the insulation shell 21, the temperature of the insulated box 2 remains stable even after it is removed from the refrigeration unit.

[0079] like Figure 6As shown, the second state is the unlocked state of the drawer component 22 and the insulation shell 21. In the second state, the locking assembly 23 is separated from the locking groove 202, and the drawer component 22 can move relative to the insulation shell 21 and be removed separately from the refrigeration compartment 101, while the insulation shell 21 can remain inside the refrigeration compartment 101. When the user does not need to use the insulation shell 21, it can be left inside the refrigeration compartment 101, and only the drawer component 22 can be removed. In this way, in the scenario where the insulation box 2 is installed inside the refrigeration compartment 101, the user can independently pull out the drawer component 22 as a storage drawer for the refrigeration unit. This not only ensures that the installation of the insulation box 2 does not occupy the space of the refrigeration unit, but the drawer component 22 inside the insulation box 2 can also store other items, and the insulation shell 21 can remain inside the refrigeration unit without requiring the user to remove the insulation shell 21 from the refrigeration compartment 101 at the same time, thus avoiding additional operation steps. The pull-out form of the drawer component 22 also greatly facilitates the user's use.

[0080] Currently, the portable insulated box 2 can be installed inside the refrigeration unit or moved out of the refrigeration unit for use outdoors or in other mobile scenarios. However, if the user does not need to move the portable insulated box 2, installing the portable insulated box 2 inside the refrigeration unit is inconvenient for the user to use the installation space. Usually, the user needs to take out the entire portable insulated box 2 before they can put or take out items, which increases the difficulty of use and leads to a waste of space in the installation location of the portable insulated box 2, reduces the actual usable space of the refrigeration unit, and reduces the user's user experience.

[0081] In this application, the insulation shell 21 is movably disposed within the refrigeration chamber 101, and the drawer assembly 22 is movably disposed within the insulation shell 21. A locking groove 202, opposite to the locking assembly 23, is provided on the side wall of the insulation shell 21. The locking assembly 23 has a first state and a second state of engaging with the locking groove 202. The user can conveniently switch the connection state between the drawer assembly 22 and the insulation shell 21 by controlling the engagement state of the locking assembly 23 with the locking groove 202. Specifically, when the locking assembly 23 is in the first state, it locks and connects the insulation shell 21 and the drawer assembly 22 to form an integral structure, allowing the user to remove the entire insulated box 2 from the refrigeration chamber 101 for outdoor activities or other scenarios requiring mobile refrigeration. When the locking assembly 23 is in the second state, it unlocks and separates the insulation shell 21 and the drawer assembly 22, allowing the drawer assembly 22 to be used independently. In daily use of the refrigeration unit, the user can independently remove the drawer 22 as a storage drawer for the refrigeration unit, while the insulation shell 21 remains inside the refrigeration chamber 101. This allows the drawer 22 of the insulation box 2 to also be used as a refrigeration space for the refrigeration unit. This not only avoids the problem of the insulation box 2 occupying space when installed inside the refrigeration chamber 101, but also improves the user's operational convenience by allowing the drawer 22 to be removed separately.

[0082] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigeration chamber 101 may be provided with a front opening 102. The insulation shell 21 can move along the front-rear direction of the refrigeration chamber 101 and be taken out of the refrigeration chamber 101 through the front opening 102.

[0083] Taking a refrigerator as an example, the refrigeration unit 101 is provided with a front opening 102. The insulation shell 21 can be moved along the front and back direction of the refrigeration chamber 101 and taken out through the front opening 102. Users only need to perform simple push and pull operations in front of the refrigeration chamber 101 to easily take out and put in the insulation shell 21, which greatly reduces the difficulty and complexity of the operation.

[0084] like Figure 3 As shown, in some embodiments, the inner wall of the refrigeration chamber 101 may be provided with support ribs 12, which extend along the front-rear direction of the refrigeration chamber 101. The insulation shell 21 is provided with a first guide rib 271, and the support rib 12 can be supported at the bottom of the first guide rib 271, so that the insulation shell 21 can slide along the top of the support rib 12 and thus enter or leave the refrigeration chamber 101.

[0085] In some embodiments, the inner wall of the refrigeration chamber 101 may be provided with a first roller 272. When the insulation shell 21 slides along the top of the support rib 12, the bottom of the first guide rib 271 contacts the first roller 272 and can move relative to the first roller 272. The first roller 272 can reduce the frictional force of the insulation shell 21 moving relative to the refrigeration chamber 101, thereby facilitating the user to remove or install the insulation box 2.

[0086] like Figure 3 and Figure 4 As shown, in some embodiments, the front side wall of the insulation housing 21 may be provided with a box opening 204. The box opening 204 and the front opening 102 of the refrigeration chamber 101 are located on the same side of the refrigeration chamber 101, so that the drawer 22 can move along the front and rear direction of the insulation chamber 201 and be taken out from the insulation chamber 201 through the box opening 204.

[0087] By placing the front opening 102 of the refrigeration chamber 101 and the box opening 204 on the front side wall of the insulation shell 21 on the same side, both the insulation shell 21 and the drawer 22 can move along the front and back direction of the refrigeration chamber 101. When retrieving items, users do not need to make cumbersome turns or search for different openings in different locations of the refrigeration device. They can simply take out the insulation shell 21 and the drawer 22 at the same time, or take out the drawer 22 alone, in this fixed area on the front side of the refrigeration chamber 101. This greatly facilitates the user's daily operation and use.

[0088] Specifically, the refrigerator may have other drawers that are movably installed inside the refrigerator and can move along the front-to-back direction of the refrigeration compartment 101. In this way, the drawer component 22 inside the insulated box 2 can be removed or installed inside the box 1 in the same direction of movement as other drawers inside the refrigerator. Even if the insulated box 2 is installed inside the refrigerator, the user can set the lock component 23 to the second state, allowing the drawer component 22 of the insulated box 2 to be used as storage space within the refrigerator. This not only fully utilizes the installation space of the insulated box 2 as storage space, but also ensures convenient and easy-to-use operation of the movable drawer component 22.

[0089] In some embodiments, the front side of the drawer assembly 22 is at least partially exposed outside the insulation housing 21, and the locking assembly 23 is disposed on the front side of the drawer assembly 22. Correspondingly, the locking groove 202 may be disposed on the peripheral edge of the box opening 204, so that the locking assembly 23 can be arranged opposite to the locking groove 202. The fact that the locking assembly 23 is disposed on the front side of the drawer assembly 22 makes it convenient for the user to operate the locking assembly 23, thereby locking or engaging the insulation housing 21 and the drawer assembly 22.

[0090] In some other embodiments, the refrigeration compartment 101 is provided with a front opening 102, and the box opening 204 can be provided on the top of the insulation shell 21. The insulation shell 21 can move along the height direction of the refrigeration compartment 101, and the user can take out the insulation shell 21 and the drawer 22 by lifting it upwards.

[0091] It should be noted that in some other embodiments, taking the refrigeration device as a horizontal freezer as an example, the horizontal freezer has a top opening, and the insulation shell 21 can move along the vertical direction of the refrigeration chamber 101 and be taken out from the refrigeration chamber 101 through the top opening.

[0092] The opening 204 can be located on the top of the insulation shell 21. Users can remove the insulation shell 21 and the drawer 22 by pulling it upwards. In this way, when users take out items, they do not need to turn around in different parts of the freezer or look for different openings. They can take out the insulation shell 21 and the drawer 22 at the same time, or take out the drawer 22 alone, from the fixed area at the top of the refrigeration compartment 101. This greatly facilitates the user's daily operation and use.

[0093] like Figure 4 As shown, in some embodiments, the inner wall of the insulation shell 21 may be provided with a sliding groove 208, and the drawer component 22 is provided with a second guide rib 281. The second guide rib 281 can be aligned and inserted into the sliding groove 208 so that the drawer component 22 can move relative to the insulation shell 21 along the sliding groove 208.

[0094] In some embodiments, the inner wall of the insulation housing 21 may be provided with a second roller 282. When the second guide rib 281 can be aligned and inserted into the slide groove 208, the bottom of the second guide rib 281 contacts the second roller 282 and can move relative to the second roller 282. The second roller 282 can reduce the frictional force of the drawer component 22 moving relative to the insulation housing 21, thereby facilitating the user to remove or install the drawer component 22 from the insulation housing 21.

[0095] In some embodiments, the refrigeration device may include a limiting device (not shown in the figure). The limiting device cooperates with the insulation shell 21 and is used to limit the movement of the insulation shell 21, so that the insulation shell 21 can maintain a stable connection with the cabinet 1 during the process of the user taking out or installing the drawer 22 from the insulation shell 21 alone, so as to prevent displacement that would affect the user's use of the drawer 22 alone.

[0096] It should be noted that, without the setting of a limit device, since the weight of the insulation shell 21 is much greater than the weight of the drawer component 22, the insulation shell 21 can remain connected to the cabinet 1 during the process of the user taking out or installing the drawer component 22 from the insulation shell 21 alone, and thus the drawer component 22 can be taken out from the refrigeration room alone.

[0097] Figure 7 for Figure 2 Schematic diagram of the insulated box; Figure 8 for Figure 7 An exploded image.

[0098] like Figure 7 and Figure 8 As shown, in some embodiments, the front side wall of the drawer component 22 may be provided with a drawer cover 221, which is used to close or open the box opening 204. The lock assembly 23 may be provided on the drawer cover 221. When the drawer cover 221 is closed on the front side of the box opening 204, the lock assembly 23 is arranged opposite to the lock groove 202.

[0099] The drawer cover 221 provided on the front side wall of the drawer component 22 can fit tightly against the front side of the box opening 204 when the box opening 204 is closed. This can effectively reduce the leakage of cold air in the refrigeration chamber 101 through the box opening 204, improve the heat preservation performance of the refrigeration device, extend the refrigeration time, and ensure that the items in the drawer can maintain a low temperature for a longer period of time.

[0100] When the drawer cover 221 is closed in front of the box opening 204, the locking assembly 23 and the locking groove 202 are arranged opposite each other. With the drawer cover 221 closed, the user can easily switch between the first and second states of the locking assembly 23 and the locking groove 202, thereby locking and unlocking the drawer component 22 and the insulation shell 21. This makes the drawer locking operation simpler and more direct. This avoids problems such as incomplete locking or structural interference caused by incorrect drawer component 22 positioning or an unclosed opening during locking, improving the directness of the locking assembly 23's operation.

[0101] like Figure 8 As shown, in some embodiments, the refrigeration device further includes a seal 5. The seal 5 may be disposed around the outside of the box opening 204. When the drawer cover 221 is closed at the front of the box opening 204, the seal 5 abuts against the front wall of the drawer cover 221 and the insulation shell 21, thereby sealing the gap between the drawer cover 221 and the peripheral edge of the box opening 204, and improving the insulation performance of the insulation cavity 201.

[0102] Figure 9 for Figure 7 A schematic diagram showing the separation of the central insulation shell from the drawer components; Figure 10 for Figure 2 A cross-sectional view; Figure 11 for Figure 10 A magnified view of part A.

[0103] like Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, the front sidewall of the insulation shell 21 is provided with a latch 24. The back side of the drawer cover 221 is provided with a insertion hole 205, and the drawer cover 221 has an insertion cavity 206 that communicates with the insertion hole 205. The insertion hole 205 is located on the back sidewall of the drawer cover 221 facing the locking groove 202. The insertion hole 205 serves as a connecting port, connecting the insertion cavity 206 to the outside, and provides an entrance for the latch 24 to extend into the interior of the drawer cover 221. The size and shape of the insertion hole 205 can be adapted to fit the latch 24.

[0104] The locking assembly 23 is movably disposed on one side of the insertion cavity 206. When the drawer cover 221 is closed at the box opening 204, the insertion hole 205 and the latch 24 are arranged opposite each other. The latch 24 can extend into the insertion cavity 206 through the insertion hole 205, and the locking assembly 23 can extend into the insertion cavity 206 and engage with the lock groove 202.

[0105] During the process of extending the drawer assembly 22 into the insulation cavity 201 through the box opening 204, since the insertion hole 205 and the latch 24 are arranged opposite each other, as the drawer assembly 22 moves towards the interior of the insulation cavity 201, the latch 24 can be inserted into the insertion cavity 206 through the insertion hole 205. This simplifies the locking state of the drawer assembly 22 and the insulation shell 21. Specifically, the user only needs to close the drawer cover 221 at the box opening 204, and the latch 24 will automatically align with the insertion hole 205 and the insertion cavity 206. Then, moving the lock assembly 23 will engage with the lock groove 202 and complete the locking.

[0106] On the other hand, the latch 24 extends into the insertion cavity 206 and engages with the lock assembly 23. The insertion cavity 206 of the drawer cover 221 can provide structural protection for the engagement between the lock assembly 23 and the latch 24. At the same time, it can make full use of the internal space of the drawer cover 221, which is conducive to making the internal structure of the insulated box 2 and the refrigeration device more compact, thereby improving space utilization and avoiding the occupation of additional storage space.

[0107] like Figure 8 As shown, in some embodiments, two locking components 23 may be provided, and correspondingly, two latches 24 may be provided. The two locking components 23 may be spaced apart on the front side wall of the drawer cover 221, and the two latches 24 may be located on both sides of the drawer opening and respectively corresponding to the locking components 23. This improves the connection strength between the insulation shell 21 and the drawer assembly 22. It should be noted that in other embodiments, multiple locking components 23 may be provided.

[0108] like Figure 11 As shown, in some embodiments, the lock assembly 23 may include a rotating member 231, which is rotatably disposed on the side wall of the drawer cover 221 and located on one side of the insertion cavity 206. When the lock assembly 23 is a manually driven structure, at least a portion of the rotating member 231 is exposed outside the drawer cover 221, thereby facilitating user operation.

[0109] Lock assembly 23 may include a latch 232. One end of the latch 232 is fixed to the rotating member 231, and the latch 232 is movable as the rotating member 231 rotates. The rotating member 231 has a first direction and a second direction, the first direction being opposite to the second direction. When the rotating member 231 rotates in the first direction, it can drive the other end of the latch 232 to extend into the insertion cavity 206 to engage with the lock groove 202. When the rotating member 231 rotates in the second direction, it can drive the other end of the latch 232 to leave the insertion cavity 206 to separate from the lock groove 202.

[0110] It should be noted that the rotation direction of the rotating component 231 has opposite first and second directions. One of the first and second directions can refer to clockwise rotation, and the other of the first and second directions can refer to counterclockwise rotation.

[0111] By arranging the rotating member 231 on one side of the insertion cavity 206, the locking tongue 232 connected to the rotating member 231 can engage with the latch 24 in the insertion cavity 206 as the rotating member 231 rotates. Specifically, when the rotating member 231 rotates in the first direction, the locking tongue 232 engages with the locking groove 202 under the action of the rotating member 231, thereby connecting the drawer cover 221 to the insulation shell 21, that is, locking the drawer 22 to the insulation shell 21. When the rotating member 231 rotates in the second direction, the locking tongue 232 separates from the locking groove 202 under the action of the rotating member 231, thereby allowing the drawer 22 to move freely inside the insulation box 2 and to be removed from the insulation box 2 independently.

[0112] like Figure 8 As shown, in some embodiments, the rotating component 231 may include a knob 2311 and a connecting rod 2312. The knob 2311 may be exposed on the front side wall of the drawer cover 221. The knob 2311 is connected to the connecting rod 2312, which extends into the insertion cavity 206. The knob 2311 allows the user to easily manually operate the engagement state between the lock assembly 23 and the lock groove 202. The latch 232 is located on the peripheral side wall of the connecting rod 2312, allowing the user to directly rotate the knob 2311, thereby driving the rotation of the connecting rod 2312 and the latch 232.

[0113] like Figure 8 As shown, in some embodiments, the drawer cover 221 is provided with a mounting part 29, which is located in the insertion cavity 206. The connecting rod 2312 is rotatably inserted into the mounting part 29, thereby limiting the rotation process of the connecting rod 2312 to ensure the reliability of the lock assembly 23 and the lock groove 202.

[0114] In some embodiments, the lock assembly 23 may further include a drive member (not shown in the figure), which is connected to the rotating member 231 in a transmission manner, thereby driving the rotating member 231 and the latch 232 to rotate. The drive member may be configured as an electric drive member, such as a drive motor. It should be noted that when the rotating member 231 is configured for manual drive, a drive member may not be required.

[0115] like Figure 8 and Figure 10As shown, in some embodiments, the insulation shell 21 includes an insulation outer shell 211, which is movably disposed within the refrigeration chamber 101. The insulation shell 21 includes an inner liner 212, which is disposed within the insulation outer shell 211, forming an insulation interlayer 206 between the inner liner 212 and the insulation outer shell 211. The insulation shell 21 includes multiple insulation panels 213, which are disposed within the insulation interlayer 206.

[0116] The insulation layer 206 is arranged around each side wall of the inner liner 212, and correspondingly, each side wall of the inner liner 212 is provided with an insulation board 213.

[0117] The insulation layer 206 is formed between the insulation outer shell 211 and the inner liner 212. Multiple insulation panels 213 are disposed within the insulation layer 206 to form a heat insulation barrier, thereby insulating the items inside the insulation cavity 201 and effectively reducing cold loss. When the locking assembly 23 and the locking groove 202 are in the second state, after the user removes the insulated box 2 from the cooling compartment 101, the insulation panels 213 help maintain the temperature inside the insulation cavity 201, thus meeting the user's needs for outdoor carrying or other mobile carrying scenarios.

[0118] On the other hand, by setting an insulation board 213 inside the insulation interlayer 206, compared with the current structure that uses an integral foam insulation layer, the insulation board 213 used in this application is advantageous in reducing the thickness of the insulation layer while ensuring the same insulation effect, thereby increasing the available storage space inside the insulation box 2.

[0119] In some embodiments, the insulation board 213 may be a vacuum insulation board, polyurethane foam material or other high-efficiency insulation material, and may be arranged in a modular manner to fill the entire interlayer space.

[0120] In some embodiments, the refrigeration device may include a refrigeration duct for delivering cold air generated by the refrigeration system to the refrigeration chamber 101, thereby cooling the refrigeration chamber 101.

[0121] Figure 12 for Figure 2 Another cross-sectional view; Figure 13 This is a schematic diagram showing the fit between the insulation shell and the air nozzle. Figure 14 This is a schematic diagram showing the separation of the insulation shell and the air nozzle.

[0122] like Figure 12 , Figure 13 and Figure 14As shown, in some embodiments, the cooling chamber 101 is provided with an air supply nozzle 3, which can be installed on and connected to the cooling air duct. The air supply nozzle 3 is used to deliver cold air. The air supply nozzle 3 can directionally deliver cold air into the interior of the insulation shell 21, thereby reducing the temperature of the insulation cavity 201 to achieve a cooling effect.

[0123] The outer wall of the insulation shell 21 is provided with a first connecting port 2071, which can connect the insulation cavity 201 to the outside when it is open. The insulation shell 21 is provided with a first sealing plate 251, which is movably provided at the first connecting port 2071 and is used to close or open the first connecting port 2071.

[0124] like Figure 14 As shown, the first connecting port 2071 is arranged opposite to the air nozzle 3. The air nozzle 3 can be set on the wall surface of the refrigeration chamber 101 that is close to or attached to the insulation shell 21. For example, the air nozzle 3 can be set on the back side wall of the refrigeration chamber 101, which is opposite to and attached to the back of the insulation shell 21.

[0125] like Figure 13 As shown, when the insulation shell 21 is installed in the refrigeration chamber 101, the air nozzle 3 can extend into the first communication port 2071 and push open the first sealing plate 251 so that the air nozzle 3 extends into the insulation cavity 201 and the air nozzle 3 communicates with the insulation cavity 201.

[0126] Specifically, by movably installing a first sealing plate 251 inside the insulation shell 21, the first sealing plate 251 can automatically open the first communication port 2071 according to the installation status between the insulation shell 21 and the refrigeration unit housing 1. When the insulation shell 21 is not installed in the refrigeration chamber 101, the first sealing plate 251 closes the first communication port 2071, effectively preventing the cold air in the insulation chamber 201 from leaking into the external environment; when the insulation shell 21 is installed in the refrigeration chamber 101, the air nozzle 3 opens the first sealing plate 251 to deliver cold air. In this way, without the need for complicated operation or settings by the user, the insulation chamber 201 can be cooled by the air nozzle 3 simply by installing the insulation box 2 inside the housing 1.

[0127] On the other hand, by arranging the air nozzle 3 and the first connecting port 2071 relative to each other and by using the movable first sealing plate 251, the air nozzle 3 can be precisely connected to the insulation shell 21. No additional air supply connection pipes or complex structures are needed to deliver cold air to the insulation box 2, which can save space in the refrigeration room 101 and is conducive to placing more items or achieving a more reasonable layout in a limited space.

[0128] In some embodiments, the size of the first connection port 2071 can be larger than the size of the air nozzle 3, so that the air nozzle 3 can deliver cold air into the insulation cavity 201. The air in the insulation cavity 201 can also flow back into the interior of the cooling chamber 101 through the first connection port 2071, thereby completing the airflow circulation within the insulation shell 21.

[0129] In some embodiments, the refrigeration chamber 101 may be equipped with a return air nozzle 4, which may be installed on and connected to the refrigeration duct. The return air nozzle 4 is used to deliver cold air. The return air nozzle 4, in conjunction with the supply air nozzle 3, allows the supply air nozzle 3 to directionally deliver cold air into the interior of the insulation shell 21. Air in the insulation cavity 201 can be delivered to the refrigeration chamber 101 for return air through the return air nozzle 4, or returned through a specific return air channel in the refrigeration duct.

[0130] like Figure 12 As shown, a second connecting port 2072 is provided on the outer wall of the insulation shell 21. When the second connecting port 2072 is open, it can connect the insulation cavity 201 to the outside. A second sealing plate 252 is provided inside the insulation shell 21. The second sealing plate 252 is movably provided at the second connecting port 2072 and is used to close or open the second connecting port 2072.

[0131] The second connecting port 2072 is arranged opposite to the return air nozzle 4. When the insulation shell 21 is installed in the refrigeration chamber 101, the return air nozzle 4 can extend into the second connecting port 2072 and push open the second sealing plate 252 so that the return air nozzle 4 can extend into the insulation cavity 201 and communicate with the insulation cavity 201.

[0132] Specifically, by movably installing a second sealing plate 252 inside the insulation shell 21, the second sealing plate 252 can automatically open the second communication port 2072 according to the installation status between the insulation shell 21 and the refrigeration unit housing 1. When the insulation shell 21 is not installed in the refrigeration chamber 101, the second sealing plate 252 closes the second communication port 2072, effectively preventing the cold air in the insulation chamber 201 from leaking into the external environment. When the insulation shell 21 is installed in the refrigeration chamber 101, the return air nozzle 4 opens the second sealing plate 252 to deliver cold air. In this way, without the need for complicated operation or settings by the user, simply installing the insulation box 2 inside the housing 1 allows the airflow in the insulation chamber 201 to circulate to the outside through the return air nozzle 4.

[0133] On the other hand, by arranging the return air nozzle 4 and the second connecting port 2072 relative to each other and by using the movable second sealing plate 252, the return air nozzle 4 can be precisely connected to the insulation shell 21. Without the need for additional return air connection pipes or complex structures, the airflow inside the insulation box 2 can be transported outward. This not only saves space in the refrigeration chamber 101, which is conducive to placing more items or achieving a more reasonable layout in a limited space, but also effectively completes the airflow circulation in the insulation cavity 201, thereby achieving a better refrigeration and insulation effect.

[0134] In some embodiments, the size of the first connecting port 2071 can be adapted to the size of the air supply nozzle 3, and the size of the second connecting port 2072 can be adapted to the size of the return air nozzle 4, which is conducive to good airflow circulation between the insulation cavity 201 and the cooling chamber 101.

[0135] like Figure 12 As shown, in some embodiments, the first connection port 2071 and the second connection port 2072 may be located on the same side of the insulation shell 21. For example, the first connection port 2071 and the second connection port 2072 may be located alternately on the back side of the insulation shell 21. Correspondingly, the air supply nozzle 3 and the air return nozzle 4 are located alternately on the back side wall of the refrigeration chamber 101.

[0136] like Figure 13 As shown, in some embodiments, the first sealing plate 251 is rotatably disposed on the peripheral edge of the first communication port 2071. Specifically, the first sealing plate 251 is hinged to the side of the peripheral edge of the first communication port 2071, and the first sealing plate 251 can rotate relative to the first communication port 2071 around the hinged end, thereby closing or opening the first communication port 2071.

[0137] like Figure 12 As shown, the heat insulation shell 21 is also provided with a first reset member 261. One end of the first reset member 261 is connected to the inner wall of the heat insulation shell 21, and the other end of the first reset member 261 is connected to the first sealing plate 251. The first reset member 261 can drive the first sealing plate 251 to rotate toward the first communication port 2071 to close the first communication port 2071.

[0138] By setting a first reset member 261 between the first sealing plate 251 and the insulation shell 21, when the insulation shell 21 is removed from the refrigeration chamber 101, the first sealing plate 251 is no longer subjected to the thrust of the air nozzle 3. The first reset member 261 can drive the first sealing plate 251 to automatically reset and tightly close the first communication port 2071, thereby realizing the automatic opening and closing of the first sealing plate 251. This not only improves the operational convenience of the insulation box 2, but also effectively prevents the cold air in the insulation cavity 201 from leaking into the external environment.

[0139] like Figure 12 As shown, in some embodiments, the first reset member 261 can be configured as a torsion spring. One end of the torsion spring is connected to the first sealing plate 251 away from its rotating connection end with the insulation shell 21, and the other end of the torsion spring can be connected to the insulation shell 21. The elastic force of the torsion spring can provide a force to the first sealing plate 251 to move in the direction of closing the first communication port 2071. Then, when the air nozzle 3 separates from the first sealing plate 251 and exits the insulation cavity 201, the elastic force of the torsion spring can drive the first sealing plate 251 to reset and press the first sealing plate 251 against the peripheral edge of the first communication port 2071.

[0140] like Figure 12 As shown, in some embodiments, the second sealing plate 252 is rotatably disposed on the peripheral edge of the second communication port 2072. Specifically, the second sealing plate 252 is hinged to the side of the peripheral edge of the second communication port 2072, and the second sealing plate 252 can rotate relative to the second communication port 2072 about the hinged end, thereby closing or opening the second communication port 2072.

[0141] The insulation shell 21 is also provided with a second reset member 262. One end of the second reset member 262 is connected to the inner wall of the insulation shell 21, and the other end of the second reset member 262 is connected to the second sealing plate 252. The second reset member 262 can drive the second sealing plate 252 to rotate toward the second communication port 2072 to close the second communication port 2072.

[0142] By setting a second reset member 262 between the second sealing plate 252 and the insulation shell 21, when the insulation shell 21 is removed from the refrigeration chamber 101, the second sealing plate 252 is no longer subjected to the thrust of the return air nozzle 4. The second reset member 262 can drive the second sealing plate 252 to automatically reset and tightly close the second communication port 2072, thereby realizing the automatic opening and closing of the second sealing plate 252. This not only improves the operational convenience of the insulation box 2, but also effectively prevents the cold air in the insulation cavity 201 from leaking into the external environment.

[0143] like Figure 12 As shown, in some embodiments, the second reset member 262 can be configured as a torsion spring. One end of the torsion spring is connected to the second sealing plate 252 away from its rotating connection end with the insulation shell 21, and the other end of the torsion spring can be connected to the insulation shell 21. The elastic force of the torsion spring can provide a force to the second sealing plate 252 in the direction of closing the second communication port 2072. Thus, when the air nozzle 3 separates from the second sealing plate 252 and exits the insulation cavity 201, the elastic force of the torsion spring can drive the second sealing plate 252 to reset and press the second sealing plate 252 against the peripheral edge of the second communication port 2072.

[0144] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
