Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] As a device for storing items at low temperatures, refrigerators are usually equipped with drawers. These drawers can be used to divide items into sections for easy and orderly storage, and can also provide special storage environments, such as humidity-controlled drawers and variable-temperature drawers.

[0003] In related technologies, drawers, whether located in the freezer or the refrigerator compartment, rely on the refrigerator's compartments to maintain a low temperature. Although they can be pulled out of the refrigerator, the low temperature cannot be maintained after they are removed, resulting in poor usability. Utility Model Content

[0004] This application provides a refrigerator with drawers that integrate independent cooling and heat preservation functions.

[0005] This application provides a refrigerator, which includes:

[0006] The box is constructed to form a storage compartment with an access opening;

[0007] Drawer assembly, including:

[0008] The insulation shell is constructed to form a mounting cavity with a front opening, and the insulation shell is removably installed in the storage compartment;

[0009] The drawer body is constructed to form an upward-opening storage cavity, and the drawer body is slidably disposed within the mounting cavity;

[0010] A locking structure is provided on one of the insulation shell and the drawer body, and is connected to or disconnected from the other; when the locking structure connects the insulation shell and the drawer body, the drawer body closes the front opening of the insulation shell; when the locking structure disconnects the insulation shell and the drawer body, the drawer body can be pulled out independently of the insulation shell.

[0011] A cooling air duct component is constructed to form a cooling air duct; the cooling air duct component is detachably connected to the insulation shell; when the insulation shell is installed in the storage compartment, the cooling air duct component is connected to the insulation shell, and the cooling air duct communicates with the mounting cavity and provides cold air to the mounting cavity.

[0012] The refrigerator of this application embodiment has a drawer assembly including an insulation shell and a drawer body. The insulation shell is slidably installed in the storage compartment, and the drawer body is slidably installed in the insulation shell. The drawer assembly is also provided with a locking structure to connect the insulation shell and the drawer body, or to disconnect the insulation shell and the drawer body, so that the drawer assembly has a refrigerator interior mode and a portable takeaway mode.

[0013] When the locking structure connects the insulation shell and the drawer body, the entire combination of "insulation shell + drawer body" can be pulled out of the refrigerator. The insulation performance of the insulation shell allows the items inside the drawer body to maintain a low temperature even outdoors.

[0014] When the locking mechanism disconnects the insulation shell and the drawer body, the drawer body can be pulled out independently, allowing the cold air duct components to connect and provide cold air to the mounting cavity. At this time, it is a fully functional refrigerator drawer.

[0015] In this way, the drawer assembly can be used as a regular drawer inside the refrigerator, or it can be detached and used as a portable low-temperature storage module, significantly improving the user's convenience in outdoor scenarios.

[0016] The cooling duct component of this application embodiment forms a cold air delivery channel. The cooling duct component is detachably connected to the insulation shell, which allows cold air to be directly delivered to the storage cavity when the drawer assembly is installed in the storage compartment, realizing independent cooling of the drawer; and also allows the insulation shell to be pulled out relative to the storage compartment.

[0017] By setting up a cooling air duct component to provide independent cooling for the storage cavity, the storage temperature of the drawer assembly is independent of the storage compartment, which improves the flexibility of the storage environment of the drawer assembly and enhances the convenience of using the drawer assembly.

[0018] In some embodiments of this application, the cooling air duct component is provided with a detector, and the insulation shell is provided with a trigger;

[0019] When the cooling air duct component is connected to the insulation shell, the trigger element triggers the detector to emit a signal;

[0020] A first fan is installed inside the cooling air duct, and the first fan is configured to start when the detector sends a signal.

[0021] In this embodiment, intelligent temperature regulation of the drawer assembly is achieved through the coordinated control of the detector and the first fan, both when the drawer assembly is inside and outside the refrigerator. The detector uses a trigger to sense in real time whether the insulation shell is in place, ensuring that the first fan only operates when the drawer assembly is installed in the refrigerator, thus avoiding energy waste or abnormal refrigerator compartment temperature caused by cold air delivery after the drawer assembly is removed. This design optimizes the operating efficiency of the cold air duct components while improving the portability and compatibility of the drawer assembly with various usage scenarios.

[0022] In some embodiments of this application, a connection port is provided on the rear side of the insulation shell, and the connection port communicates with the mounting cavity; when the insulation shell is installed in the storage room, the cooling air duct component is inserted into the connection port so that the cooling air duct communicates with the mounting cavity through the connection port.

[0023] When the insulation shell is installed in the storage room, the cooling air duct component is inserted into the connector to form a cooling air delivery channel. When the insulation shell is pushed into the storage room, the connector is aligned with and inserted into the end of the cooling air duct component. This ensures the integrity of the cooling air delivery path, accommodates the functional requirements of the insulation shell both inside and outside the storage room, and simplifies the installation and removal of the insulation shell.

[0024] In some embodiments of this application, a first return air vent is provided on the rear side of the insulation shell, and the first return air vent connects the mounting cavity and the storage chamber;

[0025] The first return air vent is located above the second return air vent of the storage room.

[0026] The first return air vent is located above the second return air vent. It uses gravity to make the cold air flow downwards, reducing the time it stays in the cold storage room and minimizing its impact on the temperature of the storage room.

[0027] In some embodiments of this application, a first return air duct is connected to the rear side of the insulation shell, and the first return air duct communicates with the mounting cavity through the first return air inlet;

[0028] The end of the first return air duct that is away from the first return air inlet extends downward.

[0029] In this embodiment, by setting the first return air duct close to the second return air inlet and restricting the downward extension of the bottom end of the first return air duct, the return air direction of the mounting cavity is restricted, making the bottom end of the first return air duct closer to the second return air inlet. This allows the second return air inlet to more quickly discharge the return air from the first return air duct, reducing the residence time of the return air in the storage room. This not only improves the efficiency of the circulating air path but also reduces the impact of the return air from the insulation shell on the temperature of the storage room.

[0030] In some embodiments of this application, a heat-insulating panel is provided at the front end of the drawer body; when the locking structure is connected to the drawer body, the heat-insulating panel is sealed to the front end of the heat-insulating shell.

[0031] With the above setup, the insulation panel and the insulation shell form a complete, six-sided insulated, sealed space. When the drawer assembly is used independently outside the refrigerator, it can reduce the intrusion of heat from the opening and extend the cooling time when used outdoors.

[0032] Furthermore, when the drawer assembly is installed in the storage compartment, this design reduces heat exchange between the mounting cavity and the external storage compartment, allowing the cooling energy to be more concentrated on cooling the drawer body and improving energy efficiency.

[0033] In some embodiments of this application, the drawer body is provided with a snap-fit ​​portion;

[0034] The locking structure includes:

[0035] The operating component is installed on the insulation shell;

[0036] A locking element is installed on the insulation shell and connected to the operating element; the locking element is detachably connected to the snap-fit ​​part.

[0037] An elastic element is installed on the insulation shell and located at the end of the locking element opposite to the operating element;

[0038] When the operating member is pressed and moves away from the drawer body, the elastic member is compressed, and the locking member disengages from the latching part and separates from the drawer body.

[0039] In the locked state, the preload of the elastic element forces the locking element to engage tightly with the snap-fit ​​part, forming a stable rigid connection. This ensures that the drawer body will not accidentally detach from the insulation shell during pulling out and transportation, guaranteeing safety and integrity when used as a portable unit.

[0040] When it is necessary to unlock the drawer body and the insulation shell, the user applies pressure to the operating mechanism. This force overcomes the resistance of the elastic element, driving the locking element to move away from the latch. This linear sequence of "press-move" actions provides the user with clear, direct, and reliable unlocking feedback, achieving a seamless one-button switch from a secure lock to quick release.

[0041] In some embodiments of this application, the rear side wall of the drawer body and at least one of the two side walls along the width direction of the box body are provided with a through opening, the through opening connecting the storage cavity and the mounting cavity.

[0042] This embodiment of the application provides a through-hole on the side wall of the drawer body, allowing cold air to flow between the storage cavity and the mounting cavity through the through-hole. This effectively exchanges cold energy into the drawer, directly cooling the stored items, rather than just cooling the outer wall of the drawer.

[0043] Moreover, by setting multiple through-holes, the cold air can be evenly distributed to the storage cavity of the drawer body, optimizing the cold air circulation path and improving cooling efficiency.

[0044] In some embodiments of this application, the box body includes a box shell and a box liner, the box liner is configured to form the storage compartment, and the box shell is connected to the outside of the box liner; the box liner is provided with a first mounting port;

[0045] Part of the cooling air duct component is located on the outside of the box liner, and the top end of the cooling air duct component extends from the first mounting port into the inside of the box liner and is detachably connected to the insulation shell.

[0046] Part of the cooling air duct component is hidden in the insulation layer between the inner liner and the outer shell, avoiding the occupation of the inner liner's internal space by the cooling air duct component, while ensuring the stability of the cold air delivery path and improving the overall structural rationality of the drawer module.

[0047] In some embodiments of this application, the cooling duct component includes a first connecting portion and a second connecting portion connected to each other. The first connecting portion is located on the outside of the box liner, and the extending direction of the first connecting portion intersects the extending direction of the second connecting portion.

[0048] The second connecting part extends along the pull-out direction of the insulation shell, and the second connecting part passes through the first mounting port into the inner side of the box liner and is detachably connected to the insulation shell.

[0049] With the above configuration, the first connecting part and the second connecting part achieve a segmented layout of the cooling air duct component through their intersecting extension directions. This allows the first connecting part to extend downwards to connect with the chamber where the evaporator is located, and also allows the second connecting part to extend along the pulling direction of the insulation shell. The insulation shell can be connected and disconnected from the second connecting part simply by pushing and pulling along the depth direction. The operation is simple and convenient.

[0072] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0073] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0074] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0075] Refrigerators typically have drawers, such as in the refrigerator compartment, which creates a relatively independent, enclosed space for partitioned storage and preservation. Similarly, drawers in the freezer compartment provide partitioned storage and easy access. Variable temperature drawers, for example, facilitate precise preservation and offer flexible storage environment settings.

[0076] However, current drawers rely on the refrigerator's compartments to maintain a low temperature. For example, because air ducts are installed to deliver cold air to the refrigerator compartment, the drawers in the refrigerator compartment maintain a low storage temperature. Similarly, the drawers in the freezer compartment maintain a frozen storage temperature because of the overall low-temperature environment of the freezer compartment.

[0077] This means that once the refrigerator drawer is removed from the refrigerator, it cannot maintain a low temperature, thus failing to meet the user's outdoor portability needs.

[0078] Users may need to quickly retrieve and keep chilled or frozen drinks and food at low temperatures during outdoor picnics, camping trips, or short excursions. However, the structure and function of refrigerator drawers in related technologies cannot meet this need: drawers cannot be cooled independently and lack insulation, causing their temperature to rise rapidly after being removed from the refrigerator, making it impossible to maintain a chilled or frozen state for an extended period. Furthermore, when using traditional foam insulated boxes outdoors, users must manually add ice or rely on external cooling equipment, which is cumbersome.

[0079] In view of this, the present application provides a refrigerator whose drawer integrates an independent cooling and insulation structure, so that the drawer can be used as a regular drawer in the refrigerator, or it can be used portablely without the refrigerator, so that the drawer can still maintain a low temperature after being removed from the refrigerator.

[0080] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0081] Combination Figure 1 This application provides a refrigerator, which includes: a cabinet 100, the cabinet 100 being configured to form a storage compartment with an access opening for storing items.

[0082] The access point is located on the front side of the storage compartment. For example... Figure 1 As shown in the embodiment of this application, the width direction of the box 100 corresponds to... Figure 1 The X-axis direction; the depth direction of the box 100, corresponding to Figure 1 In the Y-axis direction, Figure 1 The positive direction of the Y-axis is the rear side, and the negative direction of the Y-axis is the front side; the height direction of the box 100 corresponds to... Figure 1 In the Z-axis direction, Figure 1 The positive direction of the Z-axis is the top side, and the negative direction is the bottom side.

[0083] Continue to refer to Figure 1 The refrigerator in this embodiment may also include a door 200, which is connected to the cabinet 100 to open or close the loading and unloading port.

[0084] Combination Figure 2The storage room can be provided with multiple compartments. Depending on the storage temperature of the compartments, the storage room can include at least one refrigerated compartment 121 and at least one frozen compartment 131. The internal temperature of the refrigerated compartment 121 can be maintained between approximately 0°C and 5°C to store items in refrigeration mode; the internal temperature of the frozen compartment 131 can be maintained between approximately -30°C and 0°C to store items in freezing mode.

[0085] Of course, in some refrigerators, the storage compartment can also be configured as a vacuum compartment or a variable temperature compartment, etc.

[0086] In some embodiments, reference is made to Figure 1 and Figure 2 The cold storage compartment 121 is provided with two doors 200, which are rotatably connected to the cabinet 100 and rotate in opposite directions to open and close the cold storage compartment 121.

[0087] In some embodiments, the freezer compartment 131 may be provided with one door 200 or two doors 200; or, the freezer compartment 131 may also be provided with a freezer drawer, the outer end cover of which forms a door.

[0088] Continue to refer to Figure 2 Shelves can be installed in the cold storage compartment 121 to increase storage space.

[0089] The refrigerator compartment 121 may also be equipped with a drawer 122, which is slidably installed in the refrigerator compartment 121 and can be pulled out along the depth direction. The drawer 122 can be a regular drawer, a food storage drawer, or a vacuum drawer, etc., as described in related technologies.

[0090] The refrigerator compartment 121 may also be equipped with a drawer assembly 300, which is slidably installed in the refrigerator compartment 121 and can be pulled out along the depth direction.

[0091] like Figure 2 As shown, the drawer assembly 300 and the associated drawer 122 can be arranged side by side along the width of the cabinet 100, so that the storage space layout in the refrigerator compartment 121 is reasonable.

[0092] Of course, in some possible implementations, the drawer assembly 300 can also be installed in the freezer compartment 131.

[0093] Combination Figure 3 The cabinet 100 in this embodiment may include a cabinet shell 110 and a cabinet liner. The cabinet liner is constructed to form a storage compartment, and the cabinet shell 110 is connected to the outside of the cabinet liner to form the appearance of a refrigerator.

[0094] When there are multiple storage compartments, there are multiple inner boxes, and each inner box is designated as one storage compartment. For example... Figure 3 As shown, the cabinet 100 includes a refrigerator compartment 120 and a freezer compartment 130; the refrigerator compartment 120 is provided with a refrigerator compartment 121, and the freezer compartment is provided with a freezer compartment 131.

[0095] The cabinet 100 may also include an insulation layer, which can be disposed between the liner and the outer shell 110. The insulation layer can insulate the storage compartment to minimize heat exchange between the storage compartment and the outside of the refrigerator, thus helping to ensure the refrigerator's cooling effect. The insulation layer can be formed by foaming, such as polyurethane foam.

[0096] Reference Figure 4 and Figure 5 In this embodiment, a first air duct component 140 is provided inside the freezer liner 130, and an evaporation chamber 170 is formed between the first air duct component 140 and the rear wall of the freezer liner 130. An evaporator is installed inside the evaporation chamber 170. A freezer compartment 131 is formed on the front side of the first air duct component 140.

[0097] The first air duct component 140 forms a refrigeration air duct, and a second fan 141 is installed inside the refrigeration air duct. The refrigeration air duct connects the evaporation chamber 170 and the refrigeration chamber 131. Under the action of the second fan 141, the low-temperature air in the evaporation chamber 170 enters the refrigeration chamber 131 through the refrigeration air duct.

[0098] The bottom end of the first air duct component 140 is spaced from the freezer liner 130 to form a freezer return air vent, which connects the freezer compartment 131 and the bottom of the evaporator chamber 170. In this way, the air in the freezer compartment 131 returns to the evaporator chamber 170 through the freezer return air vent and exchanges heat with the evaporator.

[0099] In this embodiment, a second air duct component is further provided inside the refrigerator liner 120 to form a refrigerated air duct. A refrigerated compartment 121 is formed on the front side of the second air duct component. The refrigerated air duct is connected to the refrigerated compartment 121 to supply cold air to the refrigerated compartment 121.

[0100] Reference Figure 2 and Figure 4 In this embodiment, the cabinet 100 includes a connecting pipe 150. The connecting pipe 150 is located outside the freezer liner 130 and the refrigerator liner 120, and is connected to both the freezer liner 130 and the refrigerator liner 120. The refrigerator air duct is connected to the freezer air duct through the connecting pipe 150. Thus, under the action of the second fan 141, the cold air in the evaporation chamber 170 enters the refrigerator compartment 121 through the freezer air duct, the connecting pipe 150, and the refrigerator air duct.

[0101] In some embodiments of this application, such as Figure 2 and Figure 4 As shown, the cabinet 100 in this embodiment may further include a second return air duct 160, which is connected to the bottom of the refrigerator compartment 120 and the freezer compartment 130 respectively. The refrigerator compartment 121 is connected to the bottom of the evaporator chamber 170 through the second return air duct 160, so that the air in the refrigerator compartment 121 can return to the evaporator chamber 170 through the second return air duct 160.

[0102] Continue to refer to Figure 2 , Figure 4 as well as Figure 5 The refrigerator in this embodiment may also include a cooling air duct component 400, which is configured to form a cooling air duct 401 for supplying cold air to the drawer assembly 300.

[0103] In this embodiment, the cabinet liner is provided with a first mounting port; part of the cooling air duct component 400 is located on the outside of the cabinet liner, and the top end of the cooling air duct component 400 passes through the first mounting port into the inside of the cabinet liner and is detachably connected to the drawer assembly 300.

[0104] Part of the structure of the cooling air duct component 400 is hidden in the insulation layer between the inner box and the outer shell 110, which avoids the cooling air duct component 400 occupying the internal space of the inner box, while ensuring the stability of the cold air delivery path and improving the overall structural rationality of the drawer module.

[0105] A portion of the cooling air duct component 400 is located on the outside of the freezer liner 130 and the refrigerator liner 120.

[0106] Combination Figure 5 The refrigerator liner 120 is provided with a first mounting port so that the top end of the cooling air duct component 400 can be inserted into the interior of the refrigerator liner 120 through the first mounting port for connection with the drawer assembly 300.

[0107] The freezer liner 130 is provided with a second mounting port so that the bottom end of the cooling air duct component 400 can be inserted into the interior of the freezer liner 130 through the second mounting port, so that the cooling air duct 401 is connected to the evaporation chamber 170.

[0108] In some embodiments of this application, reference continues to be made to Figure 5 A first fan 470 is installed in the cooling air duct 401. The first fan 470 is configured to drive the cold air in the evaporator chamber 170 through the cooling air duct 401 into the drawer assembly 300 when it is started.

[0109] The cooling air duct component 400 may include a fan housing 410, which is installed inside the freezer liner 130. A portion of the cooling air duct 401 is formed between the fan housing 410 and the rear wall of the freezer liner 130, and a first fan 470 is installed between the fan housing 410 and the freezer liner 130. A gap exists between the fan housing 410 and the first air duct component 140 to form an evaporation chamber 170. An opening is formed on the front side of the fan housing 410 to connect the evaporation chamber 170 and the portion of the cooling air duct 401 on the rear side of the fan housing 410.

[0110] The cooling air duct component 400 may include a duct section 420, which is located outside the freezer liner 130 and whose bottom end is connected to the freezer liner 130. The duct section 420 communicates with the cooling air duct 401 portion on the rear side of the air casing 410 through a second mounting port.

[0111] The cooling duct component 400 may include a connector 430, one end of which is connected to the top of the duct section 420, and the other end of which extends into the interior of the refrigerator liner 120 through a first mounting port and is connected to the drawer assembly 300.

[0112] In this embodiment, the drawer assembly 300 is further provided with a return air structure, which connects the drawer assembly 300 and the evaporation chamber 170, so that the drawer assembly 300 can return air to the evaporation chamber 170.

[0113] The return air structure can be a return air duct with an insulation layer, similar to the second return air duct 160, which connects the refrigerator liner 120 and the freezer liner 130 to realize the return air of the drawer assembly 300.

[0114] Or, combine Figure 6 The drawer assembly 300 is connected to a first return air duct 500, which connects the drawer assembly 300 and the storage compartment, allowing the return air from the drawer assembly 300 to enter the storage compartment, thus simplifying the return air structure of the drawer assembly 300.

[0115] The first return air duct 500 is located above the second return air inlet 123 of the storage room. This arrangement allows the return air from the first return air duct 500 to flow downwards under gravity, reducing the residence time of the return air from the drawer assembly 300 in the storage room and minimizing its impact on the temperature of the storage room.

[0116] Combination Figure 7 In this embodiment of the application, the drawer assembly 300 includes: an insulation shell 310, which is configured to form a mounting cavity 311 with a front opening, and the insulation shell 310 is pull-out disposed in the storage compartment.

[0117] The insulation shell 310 is a drawer frame structure with insulation function, used to wrap the drawer body 320 and reduce cold loss. The insulation shell 310 has an insulation layer to ensure the insulation performance of the insulation shell 310. The insulation layer can be insulation foam.

[0118] The insulation shell 310 may include an outer shell and an inner shell, as well as an insulation layer formed by foaming between the inner shell and the outer shell.

[0119] The insulation shell 310 is provided with first slide rails 312 on both sides along the width direction of the box body 100, and the first slide rails 312 extend along the depth direction of the box body. A second slide rail is provided in the storage compartment, and the second slide rail cooperates with the first slide rail 312 to allow the insulation shell 310 to be pulled out along the depth direction.

[0120] The structure of the first slide rail 312 and the second slide rail can be the same as the slide rail structure of the relevant drawer 122, which helps to improve the versatility of the drawer assembly 300.

[0121] Continue to refer to Figure 7 The drawer assembly 300 may also include a drawer body 320, which is configured to form an upwardly opening storage cavity 321 and is removably disposed in the mounting cavity 311.

[0122] The drawer body 320 has a storage cavity 321 for storing items. The storage cavity 321 opens upwards to facilitate the retrieval and placement of items.

[0123] The drawer body 320 has third slide rails 325 on both sides along the width direction of the box body 100, and the insulation shell 310 has two fourth slide rails 315, which are spaced apart along the width direction. Both the fourth slide rails 315 and the third slide rails 325 extend along the depth direction. The fourth slide rails 315 cooperate with the third slide rails 325 to allow the drawer body 320 to be pulled out along the depth direction.

[0124] In this embodiment, there is a gap between the top of the drawer body 320 and the inner top wall of the insulation shell 310, and a gap between the rear end of the drawer body 320 and the inner rear wall of the insulation shell 310, so that cold air in the mounting cavity 311 can enter the drawer body 320.

[0125] Based on this, the drawer body 320 of this application embodiment is also provided with other openings, so that the storage cavity 321 communicates with the mounting cavity 311, so as to improve the cooling effect inside the drawer body 320.

[0126] Continue to refer to Figure 7 The drawer body 320 has a through opening 322 on its rear side wall and at least one of the two side walls along the width direction of the box body 100. The through opening 322 connects the storage cavity 321 and the mounting cavity 311.

[0127] The through opening 322 is an opening that penetrates the thickness of the side wall of the drawer body 320 and is used to connect the storage cavity 321 and the mounting cavity 311.

[0128] For example, the rear side wall of the drawer body 320 is provided with a plurality of through openings 322, which are spaced apart along the width direction.

[0129] For example, the drawer body 320 has multiple through openings 322 on its two side walls along the width direction, and the multiple through openings 322 are arranged at intervals along the depth direction.

[0130] exist Figure 7 In this design, the through opening 322 is an elongated opening extending along the height direction, but this is not a limitation on the shape of the through opening 322. The through opening 322 can also be a circular, elliptical, or other shapes.

[0131] In this embodiment, a through-hole 322 is provided on the side wall of the drawer body 320, so that cold air flows between the storage cavity 321 and the mounting cavity 311 through the through-hole 322. The cold air can be effectively exchanged to the inside of the drawer to directly cool the stored items, rather than just cooling the outer wall of the drawer.

[0132] Moreover, by setting multiple through-holes 322, cold air can be evenly distributed to the storage cavity 321 of the drawer body 320, optimizing the cold air circulation path and improving cooling efficiency.

[0133] Continue to refer to Figure 7 The drawer assembly 300 in this embodiment may further include a locking structure 330, which is disposed on one of the insulation shell 310 and the drawer body 320, and is connected to or disconnected from the other. When the locking structure 330 connects the insulation shell 310 and the drawer body 320, the drawer body 320 closes the front opening of the insulation shell 310; when the locking structure 330 disconnects the insulation shell 310 and the drawer body 320, the drawer body 320 can be pulled out independently of the insulation shell 310.

[0134] exist Figure 7 In the middle, the locking structure 330 is provided on the heat preservation shell 310, and the locking structure 330 can be selectively connected to or disconnected from the drawer body 320.

[0135] like Figure 8As shown, when the locking structure 330 is connected to the drawer body 320, the drawer body 320 closes the front opening of the insulation shell 310. At this time, the drawer body 320 can be pulled out and moved together with the insulation shell 310. Furthermore, the drawer assembly 300 can be separated from the storage compartment, making the drawer assembly 300 an independent storage unit. Due to the insulation effect of the insulation shell 310, the drawer assembly 300 has a certain function of maintaining a low-temperature storage state.

[0136] like Figure 7 As shown, when the locking structure 330 is disconnected from the drawer body 320, the drawer body 320 can be pulled out and moved relative to the insulation shell 310, so that the drawer body 320 can be used as a storage drawer in the refrigerator.

[0137] Of course, in some implementations, the locking structure 330 can also be provided on the drawer body 320, and the locking structure 330 can be selectively connected to or disconnected from the insulation shell 310.

[0138] The locking structure 330 serves as a mechanical structure for connecting or separating the drawer body 320 from the insulation shell 310. It can achieve the connection or separation between the drawer body 320 and the insulation shell 310 through at least one action such as pressing, sliding, or rotating.

[0139] In some embodiments of this application, a heat insulation panel 323 is provided at the front end of the drawer body 320; when the locking structure 330 is connected to the drawer body 320, the heat insulation panel 323 is sealed to the front end of the heat insulation shell 310.

[0140] Thus, the insulation panel 323 can form the front side wall of the drawer body 320, and can also serve as an insulation board to close the front opening of the insulation shell 310.

[0141] A sealing gasket can also be provided on the rear side of the insulation panel 323 to improve the sealing performance between the insulation panel 323 and the front end of the insulation shell 310, which is beneficial to improving the insulation performance of the drawer assembly 300.

[0142] The insulation panel 323 can be a cover structure with a heat insulation board, and the insulation panel 323 can also be formed by a cover shell and a foamed insulation layer inside the cover shell.

[0143] With the above configuration, the insulation panel 323 and the insulation shell 310 form a complete, six-sided insulated sealed space. When the drawer assembly 300 is used independently outside the refrigerator, it can reduce the intrusion of heat from the opening and extend the cooling time when used outdoors.

[0144] Furthermore, when the drawer assembly 300 is installed in the storage compartment, this design can reduce heat exchange between the mounting cavity 311 and the external storage compartment, allowing the cooling energy to be more concentrated on cooling the drawer body 320, thereby improving energy efficiency.

[0145] It should be noted that the insulation shell 310 can create a refrigeration temperature above zero degrees Celsius for refrigerating items. The insulation shell 310 can also create a freezing temperature below zero degrees Celsius for freezing items.

[0146] When the insulation shell 310 is installed in the cold storage compartment 121, the sealed space formed by the insulation panel 323 and the insulation shell 310 can reduce heat exchange between the installation cavity 311 and the cold storage compartment 121. In particular, when a low temperature environment below zero is formed inside the insulation shell 310, the sealed space formed by the insulation panel 323 and the insulation shell 310 can prevent the cold storage compartment 121 from becoming too cold.

[0147] When the insulation shell 310 is installed in the freezer compartment 131, the insulation panel 323 and the insulation shell 310 are relatively thick so that a refrigeration temperature above zero degrees can be formed in the installation cavity 311.

[0148] Continue to refer to Figure 7 The insulation panel 323 is provided with a handle 324, which can be used as the operating position of the drawer body 320 and as the drawer assembly 300 when the drawer body 320 is connected to the insulation shell 310.

[0149] The handle portion 324 can be a recessed handle structure on the insulation panel 323, or a protruding handle structure on the insulation panel 323.

[0150] Continue to refer to Figure 8 The cooling air duct component 400 is detachably connected to the insulation shell 310; wherein, the connector 430 of the cooling air duct component 400 is detachably connected to the insulation shell 310.

[0151] When the insulation shell 310 is installed in the storage compartment, the cooling air duct component 400 is connected to the insulation shell 310, and the cooling air duct 401 communicates with the mounting cavity 311, providing cooling air to the mounting cavity 311. When the insulation shell 310 is removed from the storage compartment, the cooling air duct component 400 is disconnected from the insulation shell 310, without interfering with the pull-out movement of the insulation shell 310.

[0152] With the above configuration, the refrigerator of this embodiment includes a drawer assembly 300 comprising an insulation shell 310 and a drawer body 320. The insulation shell 310 is slidably installed in the storage compartment, and the drawer body 320 is slidably installed on the insulation shell 310. The drawer assembly 300 is also provided with a locking structure 330, which connects the insulation shell 310 and the drawer body 320, or disconnects the insulation shell 310 and the drawer body 320, so that the drawer assembly 300 has a refrigerator interior mode and a portable takeaway mode.

[0153] When the locking structure 330 connects the insulation shell 310 and the drawer body 320, the entire combination of "insulation shell 310 + drawer body 320" is pulled out of the refrigerator. The insulation performance of the insulation shell 310 is used to keep the items in the drawer body 320 at a low temperature outdoors.

[0154] When the locking structure 330 disconnects the insulation shell 310 and the drawer body 320, the drawer body 320 can be pulled out independently, allowing the cold air duct component 400 to connect with it and provide cold air to the mounting cavity 311. At this time, it is a fully functional refrigerator drawer.

[0155] Thus, the drawer assembly 300 can be used as a regular drawer inside the refrigerator, or detached as a portable low-temperature storage module, significantly improving user convenience in outdoor scenarios.

[0156] The cooling air duct component 400 of this application embodiment is configured to form a cold air delivery channel. The detachable connection between the cooling air duct component 400 and the insulation shell 310 allows cold air to be directly delivered to the storage cavity 321 when the drawer assembly 300 is installed in the storage compartment, thereby achieving independent cooling of the drawer; it also allows the insulation shell 310 to be pulled out relative to the storage compartment.

[0157] By setting up a cooling air duct component 400 to provide independent cooling for the storage cavity 321, the storage temperature of the drawer assembly 300 is independent of the storage chamber, which improves the flexibility of the storage environment of the drawer assembly 300 and enhances the convenience of using the drawer assembly 300.

[0158] Continue to refer to Figure 8 The cooling air duct component 400 is equipped with a detector 610, and the insulation shell 310 is equipped with a trigger 620;

[0159] When the cooling air duct component 400 is connected to the insulation shell 310, the trigger 620 triggers the detector 610 to send a signal;

[0160] The first fan 470 is configured to start when the detector 610 sends a signal.

[0161] The detector 610 is a sensor assembly used to sense the connection status between the cooling air duct component 400 and the insulation shell 310. It can be a reed switch, micro switch, etc.

[0162] The trigger 620 is a physical element used in conjunction with the detector 610 to trigger a signal from the detector 610 at a specific location. When the detector 610 is a reed switch, the trigger 620 can be a magnet disposed on the insulation shell 310. When the detector 610 is a microswitch, the trigger 620 can be a mechanical triggering structure disposed on the insulation shell 310.

[0163] The first fan 470 serves as the cold air delivery fan for the drawer assembly 300, and its operating status is controlled by the signal from the detector 610.

[0164] The detector 610, in conjunction with the trigger 620, detects whether the insulation shell 310 is installed in the storage compartment. When the insulation shell 310 is connected to the cooling air duct component 400, the trigger 620 triggers the detector 610, which sends a signal to control the first fan 470 to start. Cold air enters the mounting cavity 311 of the insulation shell 310 through the cooling air duct 401, and further enters the storage cavity 321 of the drawer body 320 for cooling through the through-hole 322.

[0165] When the insulation shell 310 detaches from the storage compartment, the trigger 620 separates from the detector 610, the detector 610 stops sending signals, and the first fan 470 shuts off to prevent cold air from continuing to flow and affecting the temperature of the storage compartment. This structure, through the linkage between the detector 610 and the first fan 470, enables dynamic temperature adjustment of the drawer assembly 300 in both the refrigerator and detached states.

[0166] It should be noted that when the first fan 470 starts, the refrigerator compressor starts, causing the evaporator to cool.

[0167] When the temperature inside the mounting cavity 311 reaches the set temperature, the first fan 470 is configured to be turned off.

[0168] The drawer assembly 300 can be detached from the storage compartment, making it inconvenient to install a temperature sensor inside the drawer assembly 300. In some possible implementations, the refrigerator controller controls the storage temperature of the drawer assembly 300 by controlling the operating time of the first fan 470.

[0169] In this embodiment, intelligent temperature regulation of the drawer assembly 300 is achieved through the coordinated control of the detector 610 and the first fan 470, both inside and outside the refrigerator. The detector 610 uses a trigger 620 to detect in real time whether the insulation shell 310 is in place, ensuring that the first fan 470 only operates when the drawer assembly 300 is installed in the refrigerator, thus avoiding energy waste or abnormal refrigerator compartment temperature caused by cold air delivery after detachment. This design optimizes the operating efficiency of the cooling air duct component 400 while improving the portability and compatibility of the drawer assembly 300 with various usage scenarios.

[0170] In some embodiments of this application, combined with Figure 9 The insulation shell 310 has a connection port 313 on its rear side, which communicates with the mounting cavity 311. When the insulation shell 310 is installed in the storage room, the cooling air duct component 400 is inserted into the connection port 313 so that the cooling air duct 401 communicates with the mounting cavity 311 through the connection port 313.

[0171] The connection port 313 is a through structure that penetrates the thickness of the rear side wall of the insulation shell 310, thereby connecting the connection port 313 to the mounting cavity 311.

[0172] When the insulation shell 310 is installed in the storage room, the cooling air duct component 400 is inserted into the connector 313 to form a cooling air delivery channel. When the insulation shell 310 is pushed into the storage room, the connector 313 is aligned with and inserted into the end of the cooling air duct component 400. This ensures the integrity of the cooling air delivery path, accommodates the functional requirements of the insulation shell 310 in both its installed and detached states, and simplifies the installation and removal of the insulation shell 310.

[0173] Furthermore, the insertion of the cooling air duct component 400 into the connection port 313 creates friction between them, which provides resistance to the insulation shell 310 when the drawer body 320 is pulled out independently, reducing the possibility of the insulation shell 310 moving as the drawer body 320 is pulled out.

[0174] Continue to refer to Figure 9 The cooling air duct component 400 includes a first connecting part 450 and a second connecting part 460 connected to each other. The first connecting part 450 is located on the outside of the box liner, and the extending direction of the first connecting part 450 intersects the extending direction of the second connecting part 460.

[0175] The second connecting part 460 passes through the first mounting port into the inside of the box liner and is detachably connected to the insulation shell 310.

[0176] The extension direction of the second connecting part 460 is consistent with the pulling direction of the heat insulation shell 310. Thus, by pushing and pulling the heat insulation shell 310 along the depth direction, the heat insulation shell 310 and the second connecting part 460 can be connected and disconnected. The operation is simple and convenient.

[0177] The first connecting part 450 extends generally along the height direction, so that the first connecting part 450 can extend downward to the freezer liner 130 to achieve communication with the evaporation chamber 170.

[0178] In this embodiment, the connector 430 includes a horizontal extension 431 and a vertical extension 432 connected to each other. The horizontal extension 431 passes through a first mounting port into the inner side of the casing and is inserted into the connector port 313, thereby achieving a detachable connection between the connector 430 and the insulation shell 310. The vertical extension 432 is located on the outer side of the casing and is connected to the air duct section 420.

[0179] The vertical extension 432 and the duct section 420 form the first connecting part 450, and the horizontal extension 431 forms the second connecting part 460.

[0180] With the above configuration, the first connecting part 450 and the second connecting part 460 achieve a segmented layout of the cooling air duct component 400 through their intersecting extension directions. This allows the first connecting part 450 to extend downwards to connect with the chamber where the evaporator is located, and also allows the second connecting part 460 to extend along the pulling direction of the insulation shell 310. The insulation shell 310 can be connected and disconnected from the second connecting part 460 simply by pushing and pulling along the depth direction. The operation is simple and convenient.

[0181] Continue to refer to Figure 9 The insulation shell 310 has a first return air vent 314 on its rear side, which connects the installation cavity 311 and the storage room.

[0182] The first return air vent 314 is an opening structure located on the rear side wall of the insulation shell 310, used to return the cold air in the mounting cavity 311 to the storage room.

[0183] Combination Figure 6 The first return air vent 314 is located above the second return air vent 123 in the storage room.

[0184] In refrigerator mode, cold air enters the mounting cavity 311 from the cooling duct 401. After cooling the drawer body 320, the air, which has increased in temperature and density, naturally sinks and flows out through the higher-positioned first return air vent 314, then returns to the evaporator chamber via the second return air vent 123 in the storage compartment. This forms a smooth circulation loop that conforms to the flow pattern of hot air, ensuring the heat exchange efficiency inside the drawer assembly 300.

[0185] The first return air vent 314 is located above the second return air vent 123. It uses gravity to make the cold air flow downward, reducing the time it stays in the cold storage room and reducing its impact on the temperature of the storage room.

[0186] Continue to refer to Figure 9 The rear side of the insulation shell 310 is connected to the first return air duct 500, and the first return air duct 500 is connected to the mounting cavity 311 through the first return air inlet 314.

[0187] The first return air duct 500 extends downward from the end opposite to the first return air outlet 314.

[0188] The first return air duct 500 can be plugged into the first return air outlet 314, and the connection method is simple.

[0189] The first return air duct 500 may include a first extension 510 and a second extension 520 connected to each other. The first extension 510 may extend in the depth direction, and the second extension 520 may extend in the height direction. The first extension 510 is connected to the mounting cavity 311 through the first return air inlet 314, and the bottom end of the second extension 520 faces the second return air inlet 123.

[0190] In this embodiment, by setting the first return air duct 500 close to the second return air inlet 123 and restricting the downward extension of the bottom end of the first return air duct 500, the return air direction of the mounting cavity 311 is restricted, so that the bottom end of the first return air duct 500 is closer to the second return air inlet 123, allowing the second return air inlet 123 to more quickly discharge the return air from the first return air duct 500, reducing the residence time of the return air in the storage room. This can improve the efficiency of the circulating air path and reduce the impact of the return air from the insulation shell 310 on the temperature of the storage room.

[0191] Reference Figure 10 , Figure 11 as well as Figure 12 In some embodiments of this application, the drawer body 320 is provided with a snap-fit ​​part 326, which is used to be detachably connected to the locking structure 330.

[0192] In this drawer body 320, the portion of the insulation panel 323 opposite to the insulation shell 310 is provided with a slot 327, the opening of which faces the insulation shell 310. The end of the slot 327 near the bottom extends upwards to form an extension slot 328. The slot 327 and the extension slot 328 are approximately L-shaped. A latching portion 326 is formed on the side of the extension slot 328 facing the insulation shell 310.

[0193] The insulation shell 310 is provided with a mounting groove 316 for mounting the locking structure 330. The top opening of the mounting groove 316 exposes part of the locking structure 330, facilitating operation of the locking structure 330. Furthermore, the mounting groove 316 opens towards the front of the insulation panel 323, allowing the locking structure 330 to extend to the outside of the mounting groove 316 and connect with the drawer body 320.

[0194] The locking structure 330 of this embodiment includes an operating member 331, which is mounted on the insulation shell 310. The mounting groove 316 includes a first groove portion 3161, the opening of which faces upward. The operating member 331 is mounted within the first groove portion 3161.

[0195] The locking structure 330 of this application embodiment may further include a locking member 332, which is installed on the heat insulation shell 310 and connected to the operating member 331; the locking member 332 is detachably connected to the snap-fit ​​part 326.

[0196] The mounting groove 316 may further include a second groove portion 3162 and a through hole portion 3163. The second groove portion 3162 is disposed at the bottom of the first groove portion 3161, and the opening of the second groove portion 3162 faces upward. The through hole portion 3163 penetrates the front sidewall of the second groove portion 3162.

[0197] The locking member 332 includes a connecting arm 3321 and a locking part 3322. The connecting arm 3321 connects the operating member 331 and the locking part 3322, and is located within the second groove 3162. The locking part 3322 extends to the outside of the mounting groove 316 through the through hole 3163. The locking part 3322 is detachably connected to the engaging part 326 via a slot 327.

[0198] In this embodiment of the application, the elastic element 333 is installed on the insulation shell 310 and is located at the end of the locking element 332 that is away from the operating element 331. Specifically, the elastic element 333 is disposed at the end of the connecting arm 3321 that is away from the operating element 331.

[0199] The mounting groove 316 may further include a third groove 3164, which is disposed at the bottom of the second groove 3162, and the opening of the third groove 3164 faces upward. The elastic member 333 is mounted on the third groove 3164 and abuts against the connecting arm 3321.

[0200] When the operating member 331 is pressed and moves away from the drawer body 320, the elastic member 333 is compressed, and the locking member 332 disengages from the latching part 326 and separates from the drawer body 320.

[0201] Continue to refer to Figure 12 When the operating member 331 is pressed, the elastic member 333 is compressed, and the operating member 331 and the locking member 332 move downward, causing the locking member 332 to disengage from the latching part 326. At this time, the locking part 3322 of the locking member 332 is located in the slot 327. Then, the operating member 331 moves in the direction away from the insulation panel 323 of the drawer body 320, causing the locking member 332 to move away from the insulation panel 323, thereby causing the locking member 332 to disengage from the slot 327, so that the locking member 332 disengages from the drawer body 320, and thus the drawer body 320 can move relative to the insulation shell 310.

[0202] When the operating member 331 is pressed and moved toward the insulation panel 323, the locking member 332 enters the slot 327; then the pressing force applied to the operating member 331 is released, so that the locking member 332 engages with the latching part 326, so that the drawer body 320 and the insulation shell 310 are connected and can move together.

[0203] In the locked state, the pre-tightening force of the elastic element 333 forces the locking element 332 to engage tightly with the latching part 326, forming a stable rigid connection. This ensures that the drawer body 320 will not accidentally detach from the insulation shell 310 during pulling and handling, thus guaranteeing the safety of use and the integrity of the unit when used as a portable unit.

[0204] When it is necessary to unlock the drawer body 320 and the insulation shell 310, the user applies pressure to the operating element 331. This force overcomes the resistance of the elastic element 333, driving the locking element 332 to move away from the latching part 326. This linear sequence of "press-move" actions provides the user with clear, direct, and reliable unlocking feedback, achieving a seamless one-button switch from a secure lock to quick release.

[0205] The locking structure 330 of this application embodiment is not only intuitive and easy to operate, greatly improving the user experience of mode switching, but its simple mechanical transmission method also ensures the durability and reliability of the structure. It is a structural guarantee for realizing the efficient and reliable switching between the fixed and portable functions of the drawer assembly 300.
