Description

Technical Field

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

[0002] Frost-free refrigerators are widely used due to their frost-free operation. As fruits, vegetables, and other foods stored in the refrigerator wilt and become less fresh over time due to reduced moisture content. Therefore, the refrigerator's moisture-retaining function is crucial.

[0003] Equipping a refrigerator with a humidifier module can increase the humidity inside. However, in related technologies, the humidifier module is located inside the refrigerator or above the door shelves, taking up a significant amount of storage space. Utility Model Content

[0004] This application provides a refrigerator whose humidification module can reduce the space occupied by the refrigerator's storage compartments.

[0005] In a first aspect, embodiments of this application provide a refrigerator, which includes:

[0006] The container is constructed to form a cold storage compartment;

[0007] A door is rotatably connected to the cabinet to open or close the refrigerator compartment; at least one door shelf is provided on the side of the door facing the refrigerator compartment;

[0008] At least one drawer is located at the bottom of the refrigerator compartment; the drawer is configured to be pull-out along the depth direction of the refrigerator compartment; along the height direction of the refrigerator, at least one of the drawers is located below all the door shelves on the door body;

[0009] A humidification module is configured to humidify the refrigerator compartment; the humidification module is installed on the side of the door facing the refrigerator compartment and is located below all the door shelves on the door.

[0010] The humidification module is configured to not interfere with the drawer when the door is open and the drawer is pulled out.

[0011] The refrigerator in this embodiment of the application humidifies the refrigerator compartment by incorporating a humidification module, thereby increasing the humidity in the refrigerator compartment and improving the preservation quality of the food. At least one drawer in the refrigerator compartment is located below all door shelves on the door body, ensuring sufficient space below the bottom door shelf to allow for drawer extraction. The humidification module is installed on the door body and does not occupy storage space in the refrigerator compartment. Furthermore, the humidification module is configured so that it does not interfere with the drawer when the door is open and the drawer is pulled out; that is, the humidification module does not affect the drawer's operation.

[0012] In some embodiments of this application, the door body includes: a door liner; when the door body closes the refrigerator compartment, the door liner faces the refrigerator compartment;

[0013] The inner liner of the door facing the cold storage compartment is constructed with two door liner ribs, and the two door liner ribs are spaced apart along the width direction of the door body;

[0014] The door shelf is installed on the two door retaining ribs;

[0015] The humidification module extends to both ends of the door frame along the width direction of the door body, respectively, to the two door ribs.

[0016] The humidification module of this embodiment has a large dimension along the width of the door, which helps to expand the liquid storage space of the humidification module, reduce the frequency of water addition, and improve the convenience of use.

[0017] In some embodiments of this application, the inner liner of the door is recessed away from the cold storage compartment to form an installation groove;

[0018] The mounting groove extends to both ends of the door body along the width direction to the two door core ribs respectively;

[0019] The humidification module is installed in the mounting slot.

[0020] In this embodiment, the humidification module is installed in the mounting groove, reducing the size of the humidification module protruding from the inner surface of the door liner, and avoiding the installation of the humidification module affecting the pulling out of the bottom drawer in the refrigerator compartment.

[0021] In some embodiments of this application, the door body further includes:

[0022] A door outer shell is connected to the outside of the door inner shell; a gap exists between the door outer shell and the door inner shell.

[0023] A door insulation component is disposed between the door outer shell and the door inner liner;

[0024] A heat insulation board is disposed between the door heat insulation component and the door inner liner, and is opposite to the mounting groove along the thickness direction of the door body; the thermal conductivity of the heat insulation board is less than that of the door heat insulation component.

[0025] In this embodiment, a heat insulation plate is provided between the door heat insulation component and the groove wall of the mounting groove. The thermal conductivity of the heat insulation plate is less than that of the door heat insulation component, so that the thermal resistance of the heat insulation plate is greater than that of the door heat insulation component, thereby improving the heat insulation performance at the mounting groove, thus ensuring the overall heat insulation performance of the door body, and thus ensuring the heat insulation performance of the refrigerator.

[0026] In some embodiments of this application, the door liner has a flat portion located on the bottom side of the mounting groove and on the side near the rotatable connection of the door body;

[0027] The flat portion is connected to the groove wall of the mounting groove; and along the thickness direction of the door body, the flat portion does not protrude from the door core rib;

[0028] The humidification module has an outer surface that is away from the inner liner of the door; along the thickness direction of the door body, the outer surface does not protrude from the planar portion.

[0029] In this embodiment, the door liner has a planar portion, and the humidification module does not protrude from the outer surface of the door liner. Thus, the humidification module is embedded in the mounting groove, preventing it from interfering with the pulling out of the bottom drawer.

[0030] In some embodiments of this application, the humidification module includes:

[0031] A shell assembly is installed on the door body; the shell assembly has the following internal structure:

[0032] The liquid storage chamber is used to store the humidifying liquid.

[0033] The mist outlet chamber is located on one side of the liquid storage chamber;

[0034] The mist outlet is connected to the mist outlet chamber and faces the cold storage compartment;

[0035] An atomizer having an inlet end and a mist outlet end, the inlet end being exposed in the liquid storage chamber and the mist outlet end being exposed in the mist outlet chamber; the atomizer is configured such that the mist outlet end generates water mist and the water mist is ejected through the mist outlet chamber and the mist outlet.

[0036] The humidification module of this application embodiment stores humidifying liquid in a storage chamber, generates humidifying water mist through an atomizer, and introduces humidifying water mist into the cold storage room through a mist outlet chamber and a mist outlet to increase the humidity of the cold storage room; the humidifying water mist sprayed by the atomizer has a fast rate, which is conducive to high humidification efficiency.

[0037] In some embodiments of this application, the mist outlet direction of the atomizer is different from the mist outlet direction of the atomizer.

[0038] The mist outlet chamber is provided with a mist guiding chamber wall, which extends from the mist outlet end to the mist outlet.

[0039] In this embodiment, the humidifying water mist is guided by the wall of the mist guiding chamber, which prevents the humidifying water mist from accumulating on the bottom wall of the mist outlet chamber and forming water droplets.

[0040] In some embodiments of this application, the humidification module is detachably installed on the door.

[0041] The humidification module of this application embodiment is detachably connected to the door, which allows the humidification module to be removed from the door for water filling, improving the flexibility of the water filling method; moreover, the detachable connection of the humidification module also facilitates the cleaning and maintenance of the humidification module.

[0042] Secondly, embodiments of this application provide a refrigerator, which includes:

[0043] The container is constructed to form a cold storage compartment;

[0044] A door is rotatably connected to the cabinet to open or close the refrigerator compartment; at least one door shelf is provided on the side of the door facing the refrigerator compartment;

[0045] A humidification module is configured to humidify the refrigerator compartment; the humidification module is located on the side of the door facing the refrigerator compartment, and the humidification module and the door shelf are staggered along the height direction of the door.

[0046] The door body has an installation groove on the side facing the cold storage compartment, and the humidification module is installed in the installation groove.

[0047] The refrigerator in this embodiment uses a humidification module to humidify the refrigerator compartment, thereby increasing the humidity and improving the preservation quality of the refrigerator. The humidification module on the door is offset from the door shelf along the height of the door, and a mounting groove is formed on the side of the door facing the refrigerator compartment, where the humidification module is installed. This reduces the protrusion of the humidification module along the thickness of the door, minimizing its impact on the storage space of the door shelf.

[0048] In some embodiments of this application, the humidification module has an outer surface facing the cold storage compartment;

[0049] The door shelf includes a bottom side plate, the inner end of which is close to the door body;

[0050] When the door shelf is provided below the humidification module, along the thickness direction of the door body, the outer surface is closer to the outer side of the door body than the inner side of the bottom side plate.

[0051] In this embodiment, the humidification module is configured such that, along the thickness direction of the door body, from the outer side to the inner side of the door body, the outer surface of the humidification module does not protrude beyond the inner side of the bottom side plate. When items are placed on the bottom side plate of the door shelf, even if the items are placed close to the inner side of the bottom side plate, the humidification module does not affect the placement of the items, thereby reducing or even avoiding the occupation of storage space on the door shelf.

Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0112] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0113] When considering installing a humidification module in a refrigerator, the first issue to consider is the placement of the humidification module.

[0114] For example, a humidifier module placed inside a drawer can humidify the space inside the drawer, but it cannot humidify the entire refrigerator compartment. Some humidifier modules even take up space in the depth direction of the drawer.

[0115] For example, the humidification module is placed inside the cabinet and can humidify the entire refrigerator compartment, but the humidification module occupies storage space.

[0116] For example, the humidification module is placed on the door, which does not take up storage space inside the cabinet.

[0117] In some refrigerators, the humidification module is positioned parallel to the bottom of the door shelf, occupying the top space of the door shelf and limiting the height of items that can be placed inside. Furthermore, the humidification module typically does not protrude beyond the horizontal area of ​​the door shelf, resulting in a small water capacity and requiring frequent disassembly and refilling. This not only affects ease of use but also risks damaging the connection and electrical structures.

[0118] In order to increase the water storage capacity of the humidification module, the humidification module is relatively large and needs to occupy the space of a door shelf, which in fact also occupies the storage space of the refrigerator.

[0119] How to design a humidification module that does not occupy storage space inside the cabinet or on the door is one of the challenges that needs to be overcome in this field.

[0120] Researchers studying refrigerator structures discovered that in some refrigerator products, such as some built-in refrigerators, the bottom door shelf is typically spaced significantly apart from the bottom of the door to allow drawers to be pulled out smoothly. This space is not effectively utilized because it needs to accommodate the drawer's movement.

[0121] Therefore, the researchers of this application installed the humidification module on the door and below the bottom shelf, so as not to occupy the storage space inside the cabinet or the storage space of the door shelf.

[0122] Furthermore, in order to avoid the humidification module affecting the drawer's pull-out function, the researchers of this application designed the humidification module to be flat and parallel to the door body, thereby reducing the space occupied by the humidification module in the thickness direction.

[0123] Considering ease of use, the humidifier module has a large water storage capacity, which can reduce the frequency of water refilling. Therefore, the researchers of this application considered how to increase the water storage capacity of the humidifier module.

[0124] The water storage volume is equal to the area of ​​the storage cavity multiplied by the thickness of the storage cavity. The area of ​​the storage cavity is the area of ​​the surface parallel to the door, and the thickness of the storage cavity is the dimension of the storage cavity along the thickness direction of the door.

[0125] To this end, on the one hand, the researchers of this application designed the humidification module to extend along the width of the door to the door ribs on both sides, and the two ends of the humidification module along the height direction are close to the bottom of the door shelf and the bottom of the door, respectively, so as to ensure that the liquid storage cavity has a large area.

[0126] On the other hand, the researchers of this application recessed the door liner outward to form a receiving groove, so that the humidification module can be installed in the receiving groove. This can increase the thickness of the liquid storage chamber and ensure that the installation of the humidification module does not affect the drawer's pull-out operation.

[0127] 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.

[0128] First, it should be noted that in this embodiment, when the refrigerator door is closed, the width of the door is aligned with the width of the refrigerator, the thickness of the door is aligned with the depth of the refrigerator, and the height of the door is aligned with the height of the refrigerator. Figure 1 In the diagram, the width of the refrigerator corresponds to the X-axis, the depth corresponds to the Y-axis, and the height corresponds to the Z-axis.

[0129] Combination Figure 1 Some embodiments of this application provide a refrigerator, which includes a cabinet 100, which can be configured to form a storage compartment for storing items.

[0130] Multiple storage compartments can be provided to expand storage space. Depending on the storage temperature of the storage compartments, the storage compartments may include at least one refrigerated compartment 101 and at least one frozen compartment 102. The internal temperature of the refrigerated compartment 101 can be maintained between approximately 0°C and 5°C for storing items in refrigeration mode; the internal temperature of the frozen compartment 102 can be maintained between approximately -30°C and 0°C for storing items in freezing mode.

[0131] In some possible implementations, at least one of the storage compartments may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be described in detail in the embodiments of this application.

[0132] For example, there may be two storage compartments, which may be stacked vertically or arranged side by side horizontally. One of them may be a refrigerator compartment 101 and the other may be a freezer compartment 102.

[0133] In some embodiments, the refrigerator body 100 may include an inner liner and an outer shell. The inner liner may be configured with storage compartments. The outer shell may be attached to the outside of the inner liner to form the appearance of the refrigerator.

[0134] The cabinet 100 may also include a cabinet insulation layer, which can be disposed between the inner liner and the outer shell. The cabinet 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.

[0135] The refrigerator of this application embodiment may further include a refrigeration system for providing cooling capacity to the storage compartment. Exemplarily, the refrigeration system may be disposed within the cabinet 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0136] During refrigeration system operation, the compressor compresses refrigerant vapor, generating high-temperature, high-pressure refrigerant vapor, and delivers it to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then delivered to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming it from a high-pressure, low-temperature liquid into a low-pressure, low-temperature liquid, which is then delivered to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside the storage compartment.

[0137] Continue to refer to Figure 1 The refrigerator in this embodiment may also include a door 200, which is rotatably connected to the cabinet 100 to open or close the storage compartment.

[0138] Each storage room can be equipped with one door 200; or, each storage room can be equipped with two doors 200, which can rotate in opposite directions to open or close the storage room.

[0139] Of course, in some possible implementations, the storage room is equipped with drawers, and the outer ends of the drawers form doors.

[0140] In some embodiments, such as Figure 1 As shown, the door body 200 may include an inner door liner 220. When the door body 200 is closed to the refrigerator compartment 101, the inner door liner 220 faces the refrigerator compartment 101.

[0141] The door 200 may include a door outer shell 240; the door outer shell 240 may be connected to the outside of the door inner liner 220 to form the appearance of the door 200. The door outer shell 240 may be rotatably connected to the cabinet 100 to allow the door 200 to open or close the refrigerator compartment 101.

[0142] The door body 200 may also include a door insulation component, which can be disposed within the gap between the inner door liner 220 and the outer door shell 240. The door insulation component insulates the storage compartment to minimize heat exchange between the storage compartment and the outside of the refrigerator, thus ensuring the refrigerator's cooling effect. The door insulation component can be a foam layer.

[0143] In some embodiments, a door shelf 210 is provided on the side of the door 200 facing the refrigerator compartment 101 to increase the storage space of the refrigerator. The door shelf 210 has an upward-opening storage cavity 211 for storing items.

[0144] like Figure 1 As shown, the door shelf 210 includes a first side plate 212 and a second side plate 213, which are arranged at intervals along the thickness direction of the door body 200. The first side plate 212 is closer to the door body 200, and the second side plate 213 is closer to the cold storage compartment 101.

[0145] The door shelf 210 may also include two end side plates 214, which are spaced apart along the width direction of the door body 200. The two end side plates 214 are respectively connected to the two ends of the first side plate 212 and the second side plate 213.

[0146] The door shelf 210 may also include a bottom side plate, which is fixed to the bottom end of the first side plate 212, the second side plate 213, and the two end side plates 214. The bottom side plate, the first side plate 212, the second side plate 213, and the two end side plates 214 together form a storage cavity 211.

[0147] In some implementations, the inner door liner 220 facing the cold storage compartment 101 is constructed with two door liner ribs 221, the two door liner ribs 221 being arranged along the height direction of the door body 200 (corresponding to...). Figure 1 The two door ribs 221 extend along the width direction of the door body 200 and are opposite to each other and spaced apart.

[0148] The door shelf 210 is mounted on two door ribs 221. Exemplarily, the two door ribs 221 are configured to form lugs on one side opposite to each other, and the two end side plates 214 of the door shelf 210 are configured to form hanging grooves, which engage with the lugs to fix the door shelf 210 to the door liner 220.

[0149] Continue to refer to Figure 1In some possible implementations, multiple door shelves 210 are provided, and the multiple door shelves 210 are arranged at intervals along the height direction of the door body 200.

[0150] For example, three door shelves 210 are provided, and the three door shelves 210 are arranged at intervals along the height direction of the door body 200.

[0151] The spacing between two adjacent door shelves 210 can be different to form different storage heights, making it convenient to store items of different heights.

[0152] In some implementations, the number of hanging ears on the door liner 221 is greater than the number of door shelves 210, so as to adjust the position of the door shelf 210 in the height direction of the door liner 220 according to actual needs, thereby improving the flexibility of storing items.

[0153] Continue to refer to Figure 1 In some embodiments, at least one drawer 110 is provided in the refrigerator compartment 101, and the drawer 110 is located at the bottom of the refrigerator compartment 101. The drawer 110 is configured to be pulled out along the depth direction of the refrigerator compartment 101 to facilitate the retrieval and placement of items in the drawer 110.

[0154] One drawer 110 may be provided, which is located at the bottom of the interior of the refrigerator compartment 101, making it convenient for users to access items by looking into the drawer 110.

[0155] Multiple drawers 110 can be provided; for example, two drawers 110 can be arranged side by side along the width of the refrigerator. Another example is... Figure 1 The two drawers 110 can be stacked along the height of the refrigerator.

[0156] In some embodiments, along the height direction of the refrigerator, at least one drawer 110 is located below all the door shelves 210 on the door body 200. This can be understood as at least one drawer 110 being located below the lowest door shelf 210 on the door body 200.

[0157] When multiple drawers 110 are stacked along the height of the refrigerator, the bottom drawer 110 can be located below all the door shelves 210 on the door body 200, such as... Figure 1 As shown.

[0158] Thus, there is a certain gap between the bottom door shelf 210 on the door body 200 and the door seal at the bottom of the door body 200, so as to provide space for the drawer 110 to be pulled out.

[0159] Typically, the door shelf 210 has a certain thickness along the thickness direction of the door body 200. In some refrigerator products, such as built-in refrigerators, the opening and closing angle of the door body 200 is affected. For example, if the maximum opening and closing angle of the door body 200 is 90°, and the drawer 110 has a large pull-out stroke, the door shelf 210 is prone to colliding with the drawer 110, affecting the pull-out of the drawer 110.

[0160] Therefore, such as Figure 1 As shown, in some embodiments, all the door shelves 210 of the door body 200 are located above the bottom drawer 110 in the refrigerator compartment 101, providing clearance for the drawer 110 to be pulled out.

[0161] In related technologies, this space is not utilized, resulting in a waste of space inside the refrigerator. Therefore, the researchers of this application have arranged functional modules within this space; these functional modules can be humidification modules 300.

[0162] In some embodiments of this application, the refrigerator may further include a humidification module 300, which is configured to humidify the refrigerator compartment 101 to increase the humidity inside the refrigerator compartment 101, thereby improving the storage quality of items inside the refrigerator compartment 101, especially for some fresh items.

[0163] like Figure 1 As shown, the humidification module 300 is installed on the side of the door 200 facing the refrigerator compartment 101, and is located below all the door shelves 210 on the door 200. That is, the humidification module 300 is located below the lowest door shelf 210.

[0164] In some embodiments of this application, a humidification module 300 is configured in the refrigerator to humidify the refrigerator compartment 101, thereby increasing the humidity within the refrigerator compartment 101 and improving the preservation quality of the refrigerator. The humidification module 300 is installed on the door 200 and does not occupy the storage space of the refrigerator compartment 101. The humidification module 300 is located below all door shelves 210 on the door 200, utilizing the space at the bottom of the lowest door shelf 210, thus not occupying the storage space of the door shelf 210.

[0165] When the door 200 is closed, the humidification module 300 is opposite to at least one of the drawers 110 along the depth direction of the refrigerator. The humidification module 300 is configured so as not to interfere with the drawer 110 when the door 200 is open and the drawer 110 is pulled out, that is, the setting of the humidification module 300 does not affect the pulling out of the drawer 110.

[0166] For example, by limiting the size of the humidification module 300 along the thickness direction of the door 200, the humidification module 300 can be made to not interfere with the drawer 110 when the door 200 is opened and the drawer 110 is pulled out.

[0167] For example, a recessed mounting portion can be formed in the inner liner 220 of the door so that the humidification module 300 is embedded in the door body 200, so that the humidification module 300 does not interfere with the drawer 110 when the door body 200 is opened and the drawer 110 is pulled out.

[0168] It is understandable that when drawer 110 is pulled out, there is a gap between humidification module 300 and drawer 110 along the width direction of the refrigerator so that humidification module 300 and drawer 110 do not interfere with each other.

[0169] Of course, in some embodiments, the humidifying module 300 can also be located in the area of ​​the inner door liner 220 away from the rotating connection side. At the maximum extended position of the drawer 110, the drawer 110 and the humidifying module 300 are spaced apart along the depth direction of the refrigerator, thus preventing interference between the humidifying module 300 and the drawer 110. In this case, the volume of the humidifying module 300 is limited, thus limiting its liquid storage space.

[0170] In some embodiments of this application, combined with Figure 2 and Figure 3 The humidification module 300 extends to both ends of the door body 200 along the width direction to the two door ribs 221 respectively.

[0171] This design allows the humidification module 300 to have a larger size along the width of the door 200, which helps to expand the liquid storage space of the humidification module 300, reduce the frequency of water addition, and improve the convenience of use.

[0172] In some embodiments of this application, the humidification module 300 and the door shelf 210 above it have a first gap along the height direction of the door body 200. Exemplarily, this first gap can be greater than 40mm. This arrangement facilitates the convenience of adding water when a water inlet is provided on the top wall of the humidification module 300.

[0173] In some embodiments of this application, a second gap exists between the humidification module 300 and the door seal below it along the height direction of the door 200. This arrangement prevents the door 200 from sagging and causing a failure in the door seal. The second gap can be greater than 3mm.

[0174] In some embodiments of this application, the dimension of the humidification module 300 along the height direction of the door 200 is larger than the dimension of the humidification module 300 along the thickness direction of the door 200. This makes the humidification module 300 have a larger dimension along the height direction of the door 200, which facilitates increasing the liquid storage space of the humidification module 300 and helps to reduce the frequency of water addition.

[0175] In some embodiments of this application, the humidification module 300 is flat and is arranged parallel to the door 200. This allows for a larger liquid storage space in the humidification module 300 by providing a larger area; it also avoids the humidification module 300 being too large along the thickness of the door 200, which could affect the operation of other components inside the refrigerator, such as the pulling out of drawers.

[0176] In some possible implementations, the humidifying module 300 is roughly in the shape of a flat cuboid. The width of the humidifying module 300 is parallel to the width of the door 200, the height of the humidifying module 300 is parallel to the height of the door 200, and the thickness of the humidifying module 300 is parallel to the thickness of the door 200. Both the height and width of the humidifying module 300 are greater than its thickness. This design results in a regular appearance for the humidifying module 300, facilitating manufacturing and installation.

[0177] Continue to refer to Figure 2 In some embodiments of this application, the inner door liner 220 is recessed away from the cold storage compartment to form a mounting groove 230.

[0178] The mounting slot 230 is offset from the door shelf 210 on the side of the door liner 220 facing the refrigerator compartment. That is, the mounting slot 230 is located in the area of ​​the door liner 220 where the door shelf 210 is not installed. For example, the mounting slot 230 is located below all door shelves 210.

[0179] The mounting groove 230 opens towards the interior of the refrigerator compartment. The mounting groove 230 has two side walls 232, spaced apart along the width of the door 200. It also has a top wall connected to the top of the two side walls 232, a bottom wall connected to the bottom of the two side walls 232, and a bottom wall 231 connected to the two side walls 232, the bottom wall, and the top wall, located at the end of the two side walls 232 facing outwards from the door 200. Thus, the bottom wall 231, the two side walls 232, the bottom wall, and the top wall together form the mounting groove 230 opening towards the interior of the refrigerator compartment.

[0180] The groove sidewall 232 is flush with the inner side of the door liner 221, making the door liner 220 have a regular structure, which facilitates processing and demolding.

[0181] The humidifier module 300 is installed in the mounting slot 230, reducing the size of the humidifier module 300 protruding from the inner surface 222 of the door liner 220, thus preventing the installation of the humidifier module 300 from affecting the pulling out of the bottom drawer in the refrigerator compartment. The inner surface 222 of the door liner 220 is the side of the door liner 220 facing the refrigerator compartment.

[0182] In some embodiments, the humidification module 300 can be fitted into the mounting groove 230 such that the shape of the humidification module 300 on the inner surface 222 of the door liner 220 matches the shape of the mounting groove 230. For example, the humidification module 300 is rectangular on the inner surface 222 of the door liner 220, and the mounting groove 230 is a rectangular mounting groove 230. This arrangement provides installation space for the humidification module 300 while preventing the mounting groove 230 from being too large and affecting the thermal insulation performance of the door 200.

[0183] In some embodiments of this application, the mounting groove 230 is along the width direction of the door body 200 (corresponding to...). Figure 2 The two ends of the humidification module 300 extend to the two door liner 221 respectively, in order to provide sufficient installation space for the humidification module 300.

[0184] In some embodiments of this application, the inner door liner 220 is recessed toward the outer door shell 240 to form a mounting groove 230, which reduces the gap between the mounting groove 230 portion of the inner door liner 220 and the outer door shell 240, thereby reducing the thickness of the door insulation component in this area, which is not conducive to the heat preservation and insulation of the door body 200.

[0185] Therefore, in some embodiments of this application, in conjunction with Figure 3 and Figure 4 The door body 200 also includes a heat insulation plate 241, which is disposed between the door heat insulation component and the door inner liner 220. The heat insulation plate 241 is opposite to the mounting groove along the thickness direction of the door body to improve the heat insulation and thermal insulation performance of the mounting groove 230 portion.

[0186] The groove wall of the mounting groove 230 includes the bottom groove wall 231, two side groove walls 232, bottom groove wall, and top groove wall.

[0187] In some embodiments, the heat insulation plate 241 is disposed between the door heat insulation component and the bottom wall 231 of the mounting groove 230, which makes the structure of the heat insulation plate 241 simple and easy to install.

[0188] The thermal conductivity of the insulation plate 241 is less than that of the door insulation component, which makes the thermal resistance of the insulation plate 241 greater than that of the door insulation component. This improves the thermal insulation performance at the mounting groove 230, thereby ensuring the overall thermal insulation performance of the door 200 and thus ensuring the thermal insulation performance of the refrigerator.

[0189] For example, the insulation panel 241 may be a vacuum insulation panel (VIP). The door insulation may be a foam layer, such as a polyurethane foam layer.

[0190] Continue to refer to Figure 2 and Figure 3In some embodiments of this application, the inner door liner 220 is provided with a flat portion 223, part of which is located on the bottom side of the mounting groove 230, and the flat portion is located on the side of the mounting groove 230 near the door body 200 for rotatable connection.

[0191] For example, the planar portion 223 is generally L-shaped. The portion of the planar portion 223 extending along the height direction of the door body 200 is located on the side of the mounting groove 230 near the rotatable connection of the door body 200; the portion of the planar portion 223 extending along the width direction of the door body 200 is located on the bottom side of the mounting groove 230.

[0192] The portion of the flat part 223 extending along the height direction of the door body 200 is located below the door liner 221 on the side near the rotating connection of the door body 200, and this portion of the flat part 223 is opposite to the bottom drawer of the refrigerator compartment along the depth direction of the refrigerator.

[0193] Combination Figure 3 and Figure 4 Along the thickness direction of the door body 200, the flat portion 223 does not protrude from the door rib 221, thus avoiding interference with the pulling out of the bottom drawer in the refrigerator compartment. In this way, the flat portion 223 does not interfere with the bottom drawer when it is pulled out.

[0194] The flat portion 223 is connected to the groove wall of the mounting groove 230. Specifically, the flat portion 223 is along the height direction of the door body (corresponding to...). Figure 3 The portion extending along the Z-axis direction is connected to the sidewall 232 of the groove, and the flat portion 223 extends along the width direction of the door body (corresponding to...). Figure 3 and Figure 4 The portion extending along the X-axis connects to the bottom groove wall.

[0195] In some embodiments, the humidification module 300 has an outer surface 311 facing away from the inner door liner 220. Along the thickness direction of the door body (corresponding to...) Figure 4 (In the Y-axis direction), the outer surface 311 does not protrude from the flat portion 223. In this way, the humidification module 300 is embedded in the mounting groove, avoiding the humidification module 300 from affecting the pulling out of the bottom drawer.

[0196] When the door is closed, the outer surface 311 of the humidification module 300 faces the cold storage compartment.

[0197] The outer surface 311 of the humidification module 300 can be flush with the flat part 223, so that the humidification module 300 can be accommodated and the installation groove is not too deep, which would affect the heat preservation performance of the door 200.

[0198] The outer surface 311 of the humidification module 300 can be lower than the flat portion 223, meaning there is a gap between the outer surface 311 of the humidification module 300 and the flat portion 223 along the thickness direction of the door. This accommodates installation and manufacturing errors of the humidification module 300, ensuring that the outer surface 311 of the humidification module 300 does not affect the pulling out of the bottom drawer.

[0199] In some embodiments of this application, the flat portion 223 may protrude from the inner surface 222 of the door liner 220 along the thickness direction of the door body. This facilitates contact between the flat portion 223 and the housing, and makes it easier to install a door sealing strip structure around the flat portion 223, thereby improving the problem of cold leakage of the door body.

[0200] Combination Figure 5 In some embodiments, the lowermost door shelf 210 on the door 200 can be opposite to the lowermost drawer 110 in the refrigerator compartment 101 along the depth direction of the refrigerator. The opening angle of the door 200 can be greater than 90° so that the lowermost door shelf 210 does not affect the pulling out of the drawer 110.

[0201] In some embodiments, the humidification module 300 on the door body 200 and the door shelf 210 are arranged alternately along the height direction of the door body 200 to avoid the installation of the humidification module 300 affecting the installation of the door shelf 210.

[0202] For example, the humidification module 300 may be located above the door shelf 210; for instance, the humidification module 300 may be arranged in... Figure 5 In areas A and B, the humidification module 300 is at a certain distance from the bottom of the refrigerator compartment 101, allowing the humidified air generated by the humidification module 300 to sink naturally, which helps to improve the humidity uniformity of the entire refrigerator compartment 101.

[0203] For example, the humidification module 300 can also be located below the door shelf 210, such as Figure 1 As shown, the humidification module 300 does not occupy the storage height space above the door shelf 210.

[0204] In this embodiment, a mounting groove is formed on the side of the door 200 facing the refrigerator compartment 101, and the humidification module 300 is installed in the mounting groove. In this way, the protrusion dimension of the humidification module 300 along the thickness direction of the door can be reduced, and the humidification module 300 occupies the storage space of the door shelf 210.

[0205] In some embodiments of this application, combined with Figure 6 and Figure 7 When a door shelf 210 is provided below the humidification module 300, along the thickness direction of the door (corresponding to...) Figure 6In the Y-axis direction, the outer surface 311 of the humidification module 300 is closer to the outer side of the door than the inner side of the bottom side plate 215 of the door shelf 210.

[0206] Thus, along the thickness direction of the door body, from the outer side to the inner side of the door body, the outer surface 311 of the humidification module 300 does not protrude from the inner side of the bottom side plate 215. When placing items on the bottom side plate 215 of the door shelf 210, even if the items are placed close to the inner side of the bottom side plate 215, the humidification module 300 does not affect the placement of the items, thereby reducing or even avoiding the occupation of storage space in the door shelf 210.

[0207] In some embodiments, along the thickness direction of the door body, the outer surface 311 of the humidification module 300 does not protrude from the inner surface 222 of the door liner 220, so that even if the humidification module 300 is located above the door shelf 210, it does not affect the storage space of the door shelf 210.

[0208] In some embodiments of this application, combined with Figure 8 The humidifier module 300 is detachably installed on the door 200. In this way, the humidifier module 300 can be removed from the door 200 for adding water, cleaning, etc., improving the convenience of using the humidifier module 300.

[0209] In some other embodiments of this application, the humidification module 300 can be filled with water on the door 200, avoiding the need to disassemble the humidification module 300 and reducing the difficulty of adding water.

[0210] In some embodiments of this application, the humidification module 300 can be filled with water either on the door 200 or removed from the door 200 for filling, making the water filling method more flexible and the humidification module 300 easier to clean and maintain.

[0211] In some embodiments, the humidification module 300 can be rotatably mounted on the door 200, and the humidification module 300 can rotate relative to the door 200 so that the water inlet 304 of the humidification module 300 is exposed, making it convenient for the user to add water.

[0212] Normally, such as Figure 8 As shown, the water inlet 304 is located on the top side of the humidification module 300, which facilitates the setting of a larger liquid storage space.

[0213] When the door 200 closes the refrigerator compartment 101, the humidification module 300 is fixed relative to the door 200 and is in a state where the humidification module 300 is not adding water. The water inlet 304 can face the top of the door 200, which can hide the water inlet 304 and reduce the possibility of water overflow from the water inlet 304.

[0214] In some embodiments of this application, when the door 200 closes the refrigerator compartment 101 and the humidification module 300 is above a door shelf 210, the projection of the door shelf 210 onto a first plane covers the water inlet 304. The first plane is a plane defined by the width and thickness directions of the door 200. Thus, when viewed from the top to the bottom of the door 200 along its height direction, the door shelf 210 blocks the water inlet 304.

[0215] In some embodiments of this application, when the door 200 closes the refrigerator compartment 101, the projection of the door 200 in the first plane covers at least a portion of the water inlet 304, so that at least a portion of the humidification module 300 is hidden inside the door 200, reducing the volume of the humidification module 300 protruding from the door 200. Thus, when viewed from the top to the bottom of the door 200 along its height direction, the door 200 blocks at least a portion of the water inlet 304.

[0216] For example, combined Figure 2 The door 200 has a mounting groove 230 on the side facing the refrigerator compartment 101. The thickness of the door 200 forming the mounting groove 230 is smaller, while the thickness of the door 200 above the mounting groove 230 is larger. When the humidifying module 300 is installed in the mounting groove 230, the projection of the portion of the door 200 above the mounting groove 230 onto the first plane covers at least part of the water inlet 304, meaning that the projection of the top wall of the mounting groove 230 onto the first plane covers at least part of the water inlet 304. This allows both the water inlet 304 to be hidden and at least part of the humidifying module 300 to be hidden within the door 200, saving space where the humidifying module 300 protrudes from the door 200.

[0217] In other possible embodiments of this application, combined with Figure 3 The water inlet 304 is located on the side of the humidification module 300 facing the refrigerator compartment 101. This arrangement improves the convenience of adding water. The water inlet 304 can be located near the top of the humidification module 300 to allow the humidification module 300 to have a larger water storage space.

[0218] Of course, in some implementations, the water inlet 304 can also be located on one side of the humidification module 300 along the width direction of the door 200. For example, the water inlet 304 is located on the side of the door 200 away from the hinge. In this way, the water inlet 304 faces the opening and closing side of the door 200, and there is enough space for water filling, which helps to improve the convenience of water filling.

[0219] In some embodiments, the humidification module 300 has a first side and a second side along the width direction of the door body 200, and one of the bottom of the humidification module 300, the first side of the humidification module 300, and the second side of the humidification module 300 is rotatably connected to the door body 200.

[0220] This allows for a certain gap between the water inlet 304 on the top side of the humidification module 300 and the door 200, making it convenient for users to add water.

[0221] In some embodiments of this application, the humidification module 300 is rotatably connected to the door 200 at its bottom, first side, or second side. This allows for both connection between the humidification module 300 and the door 200 and enables the humidification module 300 to rotate relative to the door 200, facilitating water addition by the user. The installation method of the humidification module 300 is flexible.

[0222] In some embodiments of this application, the humidification module 300 is rotatably connected to the door 200. The humidification module 300 is configured to rotate relative to the door 200 so that the water inlet 304 is moved away from the door 200, thereby creating a preset distance between the water inlet 304 and the door 200 along the thickness direction of the door 200.

[0223] For example, the bottom of the humidifying module 300 is rotatably connected to the door 200. The rotatable connection position of the humidifying module 300 and the water inlet 304 are located at opposite ends of the humidifying module 300 along the height direction of the door 200. This allows the humidifying module 300 to rotate at a small angle, resulting in a larger gap between the water inlet 304 and the door 200 along the thickness direction. The water inlet 304 is tilted outward, making the water filling operation simpler. Moreover, due to the gravity of the humidifying module 300, the rotation operation of the humidifying module 300 requires less effort.

[0224] When the humidification module 300 is installed in the mounting slot 230, the bottom of the humidification module 300 is rotatably connected to the door body 200, which can avoid interference between the rotation of the humidification module 300 and the door liner 221, making the rotatable connection of the humidification module 300 simpler.

[0225] The humidification module 300 can rotate at an unrestricted angle, allowing users to add water by rotating it at a certain angle according to their actual needs, thus offering high operational flexibility.

[0226] In some implementations of this application, the humidification module 300 is rotatably connected to the door 200, and the humidification module 300 is configured to rotate relative to the door 200 between a first position and a second position.

[0227] The first position is the position where the water inlet 304 of the humidification module 300 faces the top of the door 200, such as... Figure 3 and Figure 6As shown; at this time, the outer surface 311 of the humidification module 300 is set parallel to the inner surface 222 of the door liner 220. The second position is a position where the water inlet 304 of the humidification module 300 and the door body 200 are at a preset distance along the thickness direction of the door body 200, such as... Figure 8 and Figure 9 As shown; at this time, there is a certain angle between the outer surface 311 of the humidification module 300 and the inner surface 222 of the door liner 220.

[0228] In some embodiments of this application, the humidification module 300 is configured to rotate between a first position and a second position, thereby fixing the water filling position of the humidification module 300, which is convenient for user operation; moreover, it can reduce the possibility of the humidification module 300 rotating accidentally during water filling, ensuring the stability and reliability of the humidification module 300 during water filling, and reducing the risk of water splashing.

[0229] In some embodiments of this application, when there is a door shelf 210 above the humidification module 300, the convenience of adding water to the humidification module 300 is affected due to the limitation of the door shelf 210.

[0230] For this purpose, the humidification module 300 is configured to rotate relative to the door 200 so that the projection of the water inlet 304 onto the plane of the bottom side plate 215 of the door shelf 210 is located outside the bottom side plate 215.

[0231] With this configuration, when the humidification module 300 is in the second position, the water inlet 304 rotates to the outside of the door shelf 210, increasing the operating space for water addition, thereby improving the convenience of water addition and reducing the possibility of interference between the water inlet container and the door shelf 210.

[0232] In some other embodiments of this application, when the humidification module 300 is in the second position, the projection of the water inlet 304 on the plane of the bottom side plate 215 may be located within the bottom side plate 215, but on the side of the bottom side plate 215 away from the door body 200.

[0233] When the humidification module 300 is in the second position, its top surface is tilted outwards, causing the water inlet 304 to tilt outwards as well. The orientation of the water inlet 304 forms an angle with the height direction of the door 200, which facilitates water filling. Therefore, water filling can be achieved even if the projection of the water inlet 304 onto the plane of the bottom side plate 215 is located on the bottom side plate 215.

[0234] In some embodiments of this application, the bottom end of the humidification module 300 is rotatably mounted on the door 200. When water is added to the humidification module 300, the projection of the door 200 in the first plane does not cover the water inlet 304, so that the side of the water inlet 304 facing the refrigerator compartment 101 relative to the door 200 is exposed, making it convenient to add water through the water inlet 304.

[0235] For example, combined Figure 2 A mounting groove 230 is provided on the side of the door 200 facing the refrigerator compartment 101. The thickness of the part of the door 200 forming the mounting groove 230 is smaller, and the thickness of the part of the door 200 above the mounting groove 230 is larger. When the humidification module 300 is installed in the mounting groove 230, the projection of the part of the door 200 above the mounting groove 230 onto the first plane does not cover the water inlet 304. This ensures that the projection of the top wall of the mounting groove 230 onto the first plane does not cover the water inlet 304, thereby exposing the side of the door 200 facing the refrigerator compartment, facilitating the addition of water through the water inlet 304.

[0236] In some implementations, the water inlet 304 is located on the top side of the humidification module 300, and the door shelf 210 above the humidification module 300 and the humidification module 300 have a preset water filling interval along the height direction of the door body 200, so that water can be added into the water inlet 304 through the water filling interval.

[0237] The water filling interval should allow the water inlet of the water container to be inserted. For example, when using a purified water bottle, the water filling interval should allow the bottle opening to be inserted.

[0238] However, when the water inlet 304 is close to the door body 200 along the thickness direction of the door body 200, for example... Figure 6 The humidification module 300 shown is embedded in the door 200, but adding water may still be inconvenient. Moreover, the space between water addition intervals is not being used effectively.

[0239] Therefore, in this embodiment of the application, the humidification module 300 rotates relative to the door 200, causing the water inlet 304 to move away from the door 200 and increasing the distance between it and the door 200, thereby expanding the water filling operation space and improving the convenience of water filling.

[0240] In some embodiments, the door 200 and the humidification module 300 can be connected by a hinge, and the connection is stable and reliable.

[0241] Reference Figure 9 and Figure 10 In other embodiments, one of the door body 200 and the humidification module 300 is provided with a rotating shaft 233, and the other is constructed with a rotating hole 331; the rotating shaft 233 is rotatably installed in the rotating hole 331, so that the humidification module 300 can rotate relative to the door body 200.

[0242] For example, a pivot 233 is provided on the door body 200, and the pivot 233 is disposed on the inner door liner 220; a pivot hole 331 is provided on the humidification module 300. Thus, there is no need to drill holes in the door body 200, ensuring the integrity of the inner door liner 220 and facilitating the heat preservation of the door body 200. The pivot hole 331 on the humidification module 300 simplifies manufacturing.

[0243] For example, a pivot hole 331 is provided on the door body 200, wherein the pivot hole 331 is provided on the inner liner 220; a pivot shaft 233 is provided on the humidification module 300. In this way, there is no need to make a hole in the humidification module 300, reducing the possibility of leakage of the humidification module 300.

[0244] In this embodiment, the door 200 and the humidification module 300 are rotatably connected by a rotating shaft 233 and a rotating hole 331. The connection structure is simple and easy to process and assemble.

[0245] In some embodiments, the pivot 233 is configured to be disengaged from the pivot hole 331, making the humidification module 300 detachable from the door 200, which facilitates the removal of the humidification module 300 from the door 200 for maintenance, cleaning, water filling, etc.

[0246] Therefore, in this embodiment, the humidifier module 300 is rotatably connected to the door 200, and the humidifier module 300 is also configured to be detachable from the door 200 after rotation. Thus, after rotation, a portion of the humidifier module 300 moves away from the door 200, expanding the detachable operating space of the humidifier module 300. This reduces the effort required for rotation, improves the ease of disassembly, and simplifies and facilitates the disassembly and water filling process.

[0247] In some embodiments, the axial direction of the pivot 233 may be parallel to the inner surface 222 of the door 200. The inner surface 222 of the door 200 is the surface of the door 200 facing the refrigerator compartment 101.

[0248] For example, the axis of the rotating shaft 233 is parallel to the width direction of the door body 200. With this configuration, the rotating shaft 233 is located at the bottom of the humidification module 300, so that the bottom of the humidification module 300 is rotatably connected to the door body 200. This allows the humidification module 300 to rotate at a small angle, resulting in a larger gap between the water inlet 304 and the door body 200 along the thickness direction of the door body 200. The water inlet 304 is tilted outward, making the water filling operation simpler.

[0249] For example, the axis of the pivot 233 is parallel to the height direction of the door 200. With this configuration, the pivot 233 can be arranged on the first or second side of the humidification module 300, so that the humidification module 300 can rotate in the horizontal plane without having to overcome the gravity of the humidification module 300 during the rotation, making operation more convenient.

[0250] In actual refrigerator products, due to processing errors or installation errors, the axial direction of the rotating shaft 233 may have a certain angle with the height direction of the door body 200.

[0251] When the rotating shaft 233 is arranged along the height direction of the door body 200, and the first or second side of the humidification module 300 is rotatably connected to the rotating shaft 233, the relative position of the door body 200 and the first or second side of the humidification module 300 does not interfere with the rotation of the humidification module 300.

[0252] For example, combined Figure 33 The humidification module 300 rotates in the horizontal plane. The rotating shaft 233 is arranged along the height direction of the door body 200, and the rotating shaft 233 is located on the hinge side of the humidification module 300 facing the door body 200. The part of the hinge side of the door body 200 opposite to the humidification module 300 does not interfere with the rotation of the humidification module 300.

[0253] The water inlet 304 can be located on the top side of the humidification module 300. When the humidification module 300 rotates relative to the door 200, the water inlet 304 can be moved away from the door 200 to facilitate water filling.

[0254] The following explanation will be based on the example of the axial extension of the pivot 233 along the width direction of the door 200, with the pivot 233 located at the bottom of the humidification module 300.

[0255] In some possible implementations, two pivots 233 are provided, and the two pivots 233 are arranged coaxially. The two pivots 233 are located on the same side of the two door retaining ribs 221 facing each other. The axis of the pivots 233 is parallel to the width direction of the door body 200.

[0256] In some specific implementations, the humidification module 300 is installed in the mounting slot 230, and the two rotating shafts 233 are respectively set on the two side walls 232 of the mounting slot 230.

[0257] The humidification module 300 has rotating holes 331 on both sides along the width of the door, and the rotating holes 331 are located at the bottom of the humidification module 300. In this way, the door does not need to provide too much space for the humidification module 300 to rotate, which helps to ensure the heat preservation performance of the door.

[0258] This embodiment of the application achieves a rotatable connection between the humidification module 300 and the door body by setting two rotating shafts 233. The connection method is stable and reliable, and there is no need to set excessively long rotating shafts 233, which would increase the assembly difficulty. Moreover, by setting the rotating holes 331 on both sides of the humidification module 300 along the width direction of the door body, the exposure of the rotating connection structure can be reduced, or even hidden, improving the aesthetics of the installation of the humidification module 300.

[0259] Combination Figure 11 In some possible implementations of this application, the humidification module 300 is along the width direction of the door (corresponding to...) Figure 11 On both sides of the X-axis, there are rings 330, which form a rotating hole 331.

[0260] This can be understood as follows: the humidification module 300 has rings 330 on both sides along the width of the door to form a rotating hole 331.

[0261] This design eliminates the need for direct openings in the humidification module 300, reducing the impact on the airtightness of the liquid storage space within the humidification module 300. Furthermore, in this embodiment, the rotating hole 331 is formed using the ring body 330, eliminating the need to create a large wall thickness area for the rotating hole 331, thus facilitating the molding of the outer shell of the humidification module 300.

[0262] Continue to refer to Figure 11 In some embodiments of this application, the humidification module 300 is located along the width direction of the door (corresponding to...). Figure 11 The two sides of the structure in the X-axis direction form a recess 312. The recess 312 is recessed away from the side wall of the mounting groove.

[0263] The humidification module 300 has two first sides 313, which are opposite to each other and spaced apart along the width direction of the door. Parts of the two first sides 313 are recessed towards each other to form recesses 312.

[0264] The ring 330 is disposed in the recessed portion 312. This arrangement reduces the volume of the ring 330 protruding from the humidification module 300, thereby improving the structural compactness of the humidification module 300.

[0265] In some embodiments, the end of the ring 330 that is away from the recess 312 does not protrude from the first side 313 of the humidification module 300.

[0266] This can be understood as follows: the end of the ring body 330 that is away from the recessed portion 312 is flush with the first side surface 313, or the end of the ring body 330 that is away from the recessed portion 312 is lower than the first side surface 313, that is, the ring body 330 is located inside the recessed portion 312.

[0267] In some embodiments of this application, a recess 312 is provided on the first side 313 of the humidification module 300 to accommodate and install the ring 330, so that the ring 330 does not protrude from the first side 313. This helps to improve the structural compactness of the humidification module 300, reduces the possibility of the ring 330 being exposed on the inside of the door 200, and helps to hide the rotational connection structure between the humidification module 300 and the door.

[0268] Combination Figure 11 and Figure 12 In some embodiments of this application, the ring body 330 is provided with a disassembly opening 332, which communicates with the rotating hole 331. It can be understood that the ring body 330 is an open ring, with the disassembly opening 332 formed on the sidewall of the ring body 330.

[0269] The pivot 233 is configured to be disengaged from the pivot hole 331 through the disassembly opening 332, thereby allowing the humidification module 300 to be removed from the door 200 for maintenance, cleaning, etc., and also for adding water to the humidification module 300.

[0270] Some embodiments of this application provide a disassembly opening 332 on the ring 330 that communicates with the rotating hole 331, so that the rotating shaft 233 can be removed from the rotating shaft 233 through the disassembly opening, thereby realizing the disassembly and assembly of the humidification module 300. The structure is simple, highly operable, and easy to disassemble.

[0271] Continue to refer to Figure 11 and Figure 12 In some embodiments, the ring body 330 includes an arc-shaped ring portion 333, which forms a rotating hole 331 to facilitate the fit between the rotating shaft 233 and the rotating hole 331, allowing the humidification module 300 to rotate relative to the rotating shaft 233. Furthermore, the arc-shaped ring portion 333 is an open ring with an opening, the opening of which forms a disassembly opening 332.

[0272] In some embodiments, the ring body 330 may further include an inclined portion 334, which is connected to one end of the open end of the arc-shaped ring portion 333; the end of the inclined portion 334 away from the arc-shaped ring portion 333 is inclined toward the door body.

[0273] The inclined portion 334 is inclined away from the arc-shaped ring portion 333 at one end, and away from the vertical center line, wherein the vertical center line is along the vertical direction of the door body (corresponding to...). Figure 12 A straight line extending along the Z-axis and passing through the center of the arc-shaped ring 333.

[0274] In some embodiments of this application, the ring 330 is provided with an inclined portion 334 to guide the shaft 233 into and out of the rotating hole 331, making the disassembly operation of the shaft 233 relative to the rotating hole 331 more convenient and improving the operability of disassembling the humidification module 300.

[0275] Continue to refer to Figure 11 and Figure 12 In some embodiments of this application, the recessed portion 312 has a side rib wall 3121, and the side rib wall 3121 is perpendicular to the door body along the thickness direction of the door body (corresponding to...). Figure 12 (in the Y-axis direction) opposite. Among them, the side rib wall 3121 can be located on the side of the recess 312 away from the door body.

[0276] One end of the opening of the ring 330 is connected to the side rib wall 3121. One end of the opening of the arc-shaped ring 333 is connected to the side rib wall 3121, and the other end of the opening of the arc-shaped ring 333 is connected to the inclined portion 334.

[0277] Thus, the ring 330 not only guides the rotating shaft 233 into and out of the rotating hole 331 using the inclined portion 334, but also connects the open end of the ring 330 to the side rib wall 3121, thereby restricting the rotation of the rotating shaft 233 into and out of the rotating hole 331. Moreover, the connection between the ring 330 and the side rib wall 3121 also helps to improve the structural stability of the ring 330.

[0278] The side rib wall 3121 is located on the side of the ring body 330 facing the outer surface 311 of the humidification module 300, and can serve to shield at least part of the ring body 330.

[0279] Continue to refer to Figure 12 In some embodiments, the inner circumferential surface of the ring 330 is tangentially connected to the side rib wall 3121 facing the inner side surface of the ring 330. This arrangement can not only reduce the stress at the connection between the ring 330 and the side rib wall 3121 and improve the stability and reliability of the connection between the ring 330 and the side rib wall 3121, but also improve the smoothness of the shaft entering and exiting the rotating hole 331.

[0280] Reference Figures 11 to 12 In some possible implementations, the humidification module 300 has a back side 314 facing the door and a bottom side 315 connected to the bottom end of the back side 314.

[0281] Thus, the outer surface 311 of the humidification module 300 and the back side 314 of the humidification module 300 are aligned along the thickness direction of the door (corresponding to...). Figure 11 The humidifier modules 300 are positioned opposite each other and spaced apart (in the Y-axis direction). The back side 314 of the humidifier module 300 is the side of the humidifier module 300 facing the door.

[0282] Combination Figure 11 and Figure 12 An inclined surface 316 is provided between the back side surface 314 and the bottom side surface 315. The inclined surface 316 forms an angle with the back side surface 314, and the inclined surface 316 forms an angle with the bottom side surface 315.

[0283] Reference Figures 13 to 15 The inclined surface 316 is configured to abut against the surface of the door facing the refrigerator compartment; the humidification module 300 is configured to rotate relative to the door so that the inclined surface 316 abuts against the door.

[0284] When the humidification module 300 is installed in the mounting groove 230, the inclined surface 316 abuts against the bottom wall of the mounting groove 230, thereby limiting the rotation angle of the humidification module 300 relative to the door.

[0285] When the inclined surface 316 abuts against the door, the humidification module 300 rotates to the second position. This second position is a position where the water inlet 304 of the humidification module 300 is spaced at a predetermined interval from the door along its thickness. In other words, the position where the humidification module 300 rotates to abut against the door is the position where the humidification module 300 adds water.

[0286] In this embodiment, by providing an inclined surface 316 between the back side 314 and the bottom side 315 of the humidification module 300, at least part of the protruding connection between the back side 314 and the bottom side 315 can be flattened to avoid the rotation angle of the humidification module 300 being restricted by the door. Furthermore, the inclined surface 316 between the back side 314 and the bottom side 315 can abut against the door to limit the rotation position of the humidification module 300, ensuring the stability of the humidification module 300 when it is in the water-filling position and preventing accidental rotation of the humidification module 300 when it is filled with water.

[0287] In some embodiments, combined with Figure 16 With the water inlet facing the top of the door, the disassembly opening 332 is located below the rotating shaft 233. This arrangement allows the humidifying module 300 to press the ring 330 against the rotating shaft 233 under its own weight, improving the reliability of the fit between the rotating shaft 233 and the rotating hole and reducing the possibility of the rotating shaft 233 coming out of the rotating hole.

[0288] Combination Figure 15 When the humidifier module 300 is rotated to the water filling position, the disassembly opening 332 is rotated to the bottom of the rotating shaft 233 and tilted backward. By pulling the humidifier module 300 upward at an angle, the rotating shaft 233 can be disassembled through the disassembly opening 332. This design improves the convenience of disassembling and assembling the humidifier module 300.

[0289] It should also be noted that in this embodiment, the outer surface 311 of the humidification module 300 does not have an operating handle for disassembling and assembling the humidification module 300. This not only ensures the regularity of the appearance of the humidification module 300, but also improves the structural compactness of the humidification module 300, without encroaching on the liquid storage space of the humidification module 300. When disassembling and assembling the humidification module 300, the humidification module 300 rotates and tilts relative to the door 200, such as... Figure 14 As shown in the diagram, the user can directly disassemble the humidifier module 300 by holding the top. Furthermore, the humidifier module 300 has a relatively small dimension along the thickness direction of the door body 200, making it easy to hold. Therefore, some embodiments of this application do not require a disassembly handle on the outer surface 311 of the humidifier module 300.

[0290] The specific structure and function of the humidification module 300 in some embodiments of this application are described in detail below with reference to the accompanying drawings.

[0291] like Figure 17 and Figure 18 As shown, in some embodiments of this application, the humidification module 300 is configured to form a liquid storage chamber 301, which is used to store humidification liquid.

[0292] The water inlet of the humidification module 300 is connected to the liquid storage chamber 301 to facilitate the addition of water into the liquid storage chamber 301. Since the water inlet is located on the top side of the humidification module 300, at least a portion of the liquid storage chamber 301 extends to the top side of the humidification module 300.

[0293] In some embodiments of this application, the humidification module 300 is further configured to form a mist outlet 302, which is located on one side of the liquid storage chamber 301 and is used to receive the humidified water mist generated by the humidification module 300.

[0294] The humidification module 300 also forms a mist outlet 303, which communicates with the mist outlet chamber 302 and faces the refrigerator compartment, so that the humidified water mist in the mist outlet chamber 302 is sprayed into the refrigerator compartment. In some embodiments of this application, the mist outlet 303 is disposed on the outer surface 311 of the humidification module 300, so that the mist outlet 303 sprays humidified water mist towards the refrigerator compartment.

[0295] For example, the mist outlet 303 is disposed on the outer surface 311 of the humidification module 300 facing the refrigerator compartment. The mist outlet 303 can be an elongated opening extending along the width direction of the humidification module 300, with a large spray area, which is beneficial to improving humidification efficiency.

[0296] Continue to refer to Figure 18 and Figure 19 The humidification module 300 may include a housing assembly 310, which is mounted on a door. The housing assembly 310 is configured to form the appearance of the humidification module 300. The housing assembly 310 is configured to form at least a liquid storage chamber 301, a mist outlet chamber 302, and a mist outlet 303.

[0297] In some embodiments of this application, the shell assembly 310 is generally cuboid, and a pivot hole 331 can be formed on a first side of the shell assembly 310 along its width direction to rotatably connect with a pivot on the door, thereby realizing the rotatable connection between the humidification module 300 and the door. The water inlet 304 is provided on the top side of the shell assembly 310.

[0298] The shell assembly 310 may include a first shell portion and a second shell portion, which are fixedly connected to form a liquid storage chamber 301, a mist outlet 302, and a mist outlet 303. By providing two shell portions, the shell assembly 310 can not only enclose and form each functional cavity, but also facilitate the installation of the internal structure of the shell assembly 310.

[0299] Combination Figure 19 In some embodiments, the shell assembly 310 includes a front shell portion 317 and a rear cover plate 318. The front shell portion 317 can be a shell structure with an opening facing the door body, and the rear cover plate 318 covers the opening of the front shell portion 317. The water inlet 304 and the mist outlet 303 are both provided in the front shell portion 317.

[0300] This configuration allows the structure of each functional cavity to be formed within the front shell 317 and fixedly connected by the rear cover plate 318, thus forming each functional cavity. This reduces the assembly precision requirements between the rear cover plate 318 and the front shell 317.

[0301] In some embodiments, the front shell portion 317 includes a front side panel, a top panel, a bottom panel, a left side panel, and a right side panel. The top panel, bottom panel, left side panel, and right side panel are all disposed on the side of the front side panel facing the door. The top panel and bottom panel are respectively disposed at the top and bottom ends of the front side panel. The left side panel and right side panel are respectively disposed on the front side panel along the width direction of the door (corresponding to...). Figure 19 (in the X-axis direction). Thus, the front side plate, top plate, bottom plate, left side plate, and right side plate together enclose to form the front shell 317 facing the door opening.

[0302] The water inlet 304 is located on the top plate, and the mist outlet 303 is located on the front side plate. The inclined surface 316 is formed on the rear cover plate 318.

[0303] In some embodiments, the front housing 317 may further include a first partition plate 3171, the first partition plate 3171 being along the width direction of the door body (corresponding to...). Figure 19 Extending along the X-axis direction of the door, and with the two ends of the first partition plate 3171 connected to the left and right side plates respectively. Along the height direction of the door (corresponding to...) Figure 19 In the Z-axis direction, the first partition plate 3171 has a gap between itself and the top plate, and the first partition plate 3171 has a gap between itself and the bottom plate.

[0304] When the rear cover plate 318 is fixedly connected to the front shell 317, the first partition plate 3171 abuts against the rear cover plate 318, thereby forming a liquid storage cavity 301 above the first partition plate 3171 and a mist outlet cavity 302 below the first partition plate 3171.

[0305] Continue to refer to Figure 18 The humidification module 300 may include an atomizer 320, which is configured to generate humidifying water mist. The atomizer 320 may be an ultrasonic humidifier with high humidification efficiency and low noise. The atomizer 320 may also generate humidifying water mist using pressure atomization methods, such as spray nozzles or centrifugal atomizing devices.

[0306] In some embodiments, the atomizer 320 has an opposing water inlet and a mist outlet. The water inlet is exposed in the liquid storage chamber 301 and is in contact with the liquid in the liquid storage chamber 301. The mist outlet is exposed in the mist outlet chamber 302 to spray water mist into the mist outlet chamber 302.

[0307] The atomizer 320 is configured to generate water mist at the mist outlet and to spray the water mist through the mist outlet 302 and the mist outlet 303.

[0308] In some embodiments, the atomizer 320 is sheet-shaped, which occupies little installation space. The atomizer 320 can be arranged in a horizontal plane, thus ensuring that the water inlet of the atomizer 320 is in full contact with the liquid in the liquid storage chamber 301.

[0309] For example, the atomizer 320 can be a microporous atomizing plate. One side of the microporous atomizing plate is the water inlet end, and the other side is the mist outlet end. When the atomizer 320 vibrates, the liquid at the water inlet end is forced through the micropores of the atomizing plate and dispersed into fine droplets, which are then sprayed out from the mist outlet end of the atomizing plate to form a humidified water mist.

[0310] In some embodiments of this application, multiple atomizers 320 are provided, and the multiple atomizers 320 are arranged along the width direction of the humidification module 300 (corresponding to...). Figure 19 The interval setting (in the X-axis direction) is used to increase the amount of humidifying water mist, which helps to improve humidification efficiency.

[0311] In some embodiments, a first through hole is provided on the first partition plate 3171, and at least one end of the water inlet end of the atomizer 320 is opposite to the first through hole, so that the water inlet end of the atomizer 320 is exposed in the liquid storage chamber 301.

[0312] The atomizer 320 is sealed and installed on the first partition plate 3171, and the atomizer 320 is located inside the mist outlet chamber 302. This facilitates the electrical connection of the atomizer 320 and allows it to spray humidified water mist into the mist outlet chamber 302.

[0313] Continue to refer to Figure 18In some embodiments, the mist outlet direction of the atomizer 320 is different from the mist outlet direction of the mist outlet 303. For example, the mist outlet is downward (corresponding to...). Figure 18 Fog is emitted from the negative Z-axis direction, with the fog outlet 303 facing the cold storage compartment. Figure 18 Fog is emitted in the positive Y-axis direction, and the fog emission direction at the fog emission end is perpendicular to the fog emission direction of the fog emission port 303.

[0314] A mist guiding chamber wall 3191 is provided inside the mist outlet chamber 302. The mist guiding chamber wall 3191 extends from the mist outlet end to the mist outlet 303, which plays a role in guiding the humidifying water mist and preventing the humidifying water mist from accumulating on the bottom wall of the mist outlet chamber 302 to form water droplets.

[0315] For example, the wall 3191 of the mist guiding cavity is arc-shaped, which helps to reduce the resistance of the spray path of the humidifying water mist and increase the spray rate of the water mist.

[0316] Continue to refer to Figure 19 In some embodiments, the shell assembly 310 may further include a fog guide shell 319, which is installed inside the fog outlet chamber 302, and a portion of the structure of the fog guide shell 319 forms the fog guide chamber wall 3191. The rear cover plate 318 is provided with a clearance opening to avoid the installation of the fog guide shell 319.

[0317] The mist guide shell 319 may include a top shell wall, a bottom shell wall, and two first shell walls. The top shell wall is opposite to the first partition plate 3171; the bottom shell wall is located below the mist outlet 303. The top shell wall and the bottom shell wall are along the height direction of the humidification module 300 (corresponding to...). Figure 19 The two first shell walls are arranged at intervals along the Z-axis direction of the humidification module 300, with the first shell walls along the width direction of the humidification module 300 (corresponding to...). Figure 19 The shells are arranged at intervals along the X-axis and connected to both ends of the top and bottom shells.

[0318] A second through hole is provided on the top shell wall, and the second through hole is opposite to the first through hole along the height direction of the humidification module 300. The atomizer 320 is sealed between the first partition plate 3171 and the top shell wall.

[0319] The mist guiding cavity wall 3191 has a first end and a second end along the height direction, with the first end located above the second end. The bottom end of the mist guiding cavity wall 3191 is connected to the top shell wall and is located on the side of the second through hole facing the rear cover plate 318. The second end of the mist guiding cavity wall 3191 is connected to the end of the bottom shell wall opposite to the rear cover plate 318.

[0320] In some embodiments, the upper surface of the second end of the mist guiding cavity wall 3191 is flush with the lower surface of the mist outlet 303. This can prevent the formation of a step between the mist guiding cavity wall 3191 and the mist outlet 303, which would lead to the formation of water droplets, and can also prevent the mist guiding cavity wall 3191 from extending into the mist outlet 303 and blocking the mist outlet 303.

[0321] In some embodiments, a wire through-hole is provided on the wall 3191 of the mist guiding chamber so that the wire connected to the atomizer 320 enters through the wire through-hole to the side of the wall 3191 away from the mist outlet chamber 302, thereby reducing the influence of the wire on the mist outlet.

[0322] In some embodiments, the housing assembly 310 may further include a rear trim panel 3120, which covers the fog guide housing 319 to cover the wires inside the fog guide housing 319.

[0323] In some embodiments, the rear trim panel 3120 is flush with the rear cover panel 318, which not only ensures the regularity of the appearance of the shell assembly 310, but also makes the shell assembly 310 structurally compact.

[0324] In some embodiments of this application, the shell assembly 310 forms a mist guiding cavity wall 3191 by setting a mist guiding shell 319, which helps to simplify the structure of the front shell 317 and makes the front shell 317 easier to form; it also facilitates the installation and fixation of the atomizer 320.

[0325] The humidification module 300 in this embodiment of the application is also configured to form an electrical cavity 305, which is used for electrical components of the humidification module 300, such as the drive board of the atomizer 320. The electrical cavity 305 is not connected to the liquid storage cavity 301 to improve the safety of the electrical components inside the electrical cavity 305.

[0326] In some embodiments, combined with Figure 19 The front shell portion 317 may further include a second partition plate 3172, which can extend along the height direction of the door body (corresponding to...). Figure 19 Extending along the Z-axis direction. The top end of the second partition plate 3172 is connected to the top plate of the front shell 317, and the bottom end of the second partition plate 3172 is connected to the first partition plate 3171. Along the width direction of the door body (corresponding to...) Figure 19 (in the X-axis direction), there is a gap between the second partition plate 3172 and the left side plate, and there is a gap between the second partition plate 3172 and the right side plate.

[0327] When the rear cover plate 318 is fixedly connected to the front shell 317, the second partition plate 3172 abuts against the rear cover plate 318, thereby forming a liquid storage cavity 301 on one side of the second partition plate 3172 and an electrical cavity 305 on the other side.

[0328] Continue to refer to Figure 19In some possible implementations of this application, a first electrical connector 360 is provided on the humidification module 300, and the first electrical connector 360 is located on the top of the humidification module 300. The first electrical connector 360 is located on the top of the electrical cavity 305, facilitating electrical connection between the first electrical connector 360 and electrical components within the electrical cavity 305. For example, the first electrical connector 360 can be electrically connected to the drive plate of the atomizer 320 via a wire.

[0329] A second electrical connector is provided on the door, which is used to connect the refrigerator to the power supply.

[0330] When the humidification module 300 is fixed to the door, the first electrical connector 360 and the second electrical connector are electrically connected to supply power to the humidification module 300.

[0331] The second electrical connector can also be electrically connected to the refrigerator's controller. In this way, the first electrical connector 360 and the second electrical connector can also communicate with each other. The refrigerator's controller controls the working state of the atomizer 320 through the second electrical connector and the first electrical connector 360.

[0332] When the humidification module 300 rotates relative to the door so that the water inlet 304 and the door have a preset distance along the thickness direction of the door, the first electrical connector 360 and the second electrical connector are disconnected.

[0333] In some embodiments of this application, a first electrical connector 360 is provided on the top of the humidification module 300. The first electrical connector 360 is electrically connected to a second electrical connector provided on the door to supply power to the humidification module 300. Furthermore, the first electrical connector 360 and the second electrical connector are detachably connected, so that when the humidification module 300 rotates relative to the door to add water, the first electrical connector 360 and the second electrical connector are disconnected, preventing the humidification module 300 from being electrified and causing electric shock when adding water, thus improving the safety of the humidification module 300.

[0334] The first electrical connector 360 is located at the top of the humidification module 300. By rotating it slightly at the bottom of the humidification module 300, the first electrical connector 360 can be disconnected from the second electrical connector, which helps to ensure the timeliness and reliability of power-off of the humidification module 300.

[0335] During the opening and closing of the door, the door body 200 drives the humidification module 300 to rotate, causing the liquid in the liquid storage chamber 301 of the humidification module 300 to slosh, affecting the stability of the humidification module 300, and even causing the humidification module 300 to detach from its fixed position and rotate relative to the door body, affecting the safety of the humidification module 300.

[0336] Therefore, in some embodiments of this application, reference continues to be made to... Figure 19The liquid storage cavity 301 is provided with at least one stiffening plate 340, which divides the liquid storage cavity 301 into at least two sub-cavities.

[0337] In this embodiment, a stiffener 340 is provided in the liquid storage chamber 301, which is a large space, to divide the liquid storage chamber 301 into at least two sub-chambers. The sub-chambers are smaller, which can reduce the range of free flow of liquid in the liquid storage chamber 301 and reduce the amplitude of liquid sloshing. The stiffener 340 also acts as a barrier to the flow of liquid and reduces the amplitude of liquid sloshing, thereby improving the stability of the humidification module 300 installation.

[0338] Furthermore, the connection between two adjacent sub-cavities does not affect the flow of liquid, ensuring the consistency of water level across multiple sub-cavities.

[0339] In some possible implementations of this application, the stiffening plate 340 extends along a first direction; the first direction corresponds to the width direction of the door body (corresponding to...). Figure 19 An angle is formed between the X-axis direction and the X-axis direction.

[0340] exist Figure 19 and Figure 20 In the middle, the stiffening plate 340 is along the height direction of the door body (corresponding to...) Figure 19 The first direction extends along the Z-axis direction, that is, the first direction is parallel to the height direction of the door body, and the first direction forms a right angle with the width direction of the door body.

[0341] However, this is not a limitation on the extension direction of the stiffening plate 340. For example, the stiffening plate 340 may extend obliquely relative to the height direction of the door.

[0342] In some embodiments of this application, by setting the stiffener 340 to be elongated, not only can the area blocking the flow of liquid be increased, but the separation area between two adjacent sub-cavities can also be increased, thereby increasing the flow resistance of the liquid and reducing the degree of sloshing of the liquid in the storage cavity 301 during the opening and closing process.

[0343] Continue to refer to Figure 20 In some embodiments, multiple stiffeners 340 are provided, and the multiple stiffeners 340 are arranged at intervals along the second direction; wherein the second direction forms an angle with the first direction.

[0344] exist Figure 20 In the middle, multiple stiffening plates 340 are arranged at intervals along the width direction of the door body 200, that is, the second direction is parallel to the width direction of the door body 200, and the angle formed between the second direction and the first direction is a right angle.

[0345] This is not a limitation on the arrangement direction of the stiffening rib 340. For example, the second direction forms an angle with the width direction of the door body 200.

[0346] The number of stiffeners 340 in this embodiment is not limited. There may be six, eight or more stiffeners 340, which can be determined according to the space of the liquid storage cavity 301, the processing difficulty, etc.

[0347] The extension lengths of the multiple stiffening plates 340 can be the same or different. The extension length of the stiffening plates 340 can be set according to the actual space and structure within the liquid storage cavity 301.

[0348] In some embodiments of this application, by setting multiple stiffeners 340, it is beneficial to reduce the space between individual sub-cavities, increase the flow resistance of the liquid, and reduce the degree of sloshing of the liquid in the storage cavity 301 during the opening and closing process.

[0349] In some embodiments of this application, at least one stiffener 340 is spaced apart from the bottom wall of the liquid storage cavity 301 along the height direction of the door body.

[0350] The bottom wall of the liquid storage cavity 301 can be a first partition plate 3171, and at least one stiffener 340 is spaced apart from the first partition plate 3171.

[0351] In some embodiments of this application, by setting a gap between the stiffening plate 340 and the bottom wall of the liquid storage cavity 301, the two adjacent sub-cavities are connected, eliminating the need for an additional connection structure between the two adjacent sub-cavities, which helps to simplify the structure inside the liquid storage cavity 301.

[0352] Furthermore, by setting a gap between the stiffener 340 and the bottom wall of the liquid storage chamber 301 in this embodiment, the shaking in the liquid storage chamber 301 is smaller when the liquid in the liquid storage chamber 301 is less, and there is no need to use the stiffener 340 to reduce the shaking; moreover, it can ensure that all atomizers on the bottom wall of the liquid storage chamber 301 can contact the liquid for atomization, avoiding the situation where some atomizers have water while others do not due to uneven liquid distribution.

[0353] When multiple stiffeners 340 are provided, the multiple stiffeners 340 and the bottom wall of the liquid storage chamber 301 are spaced apart along the height direction of the door body so that the two adjacent sub-chambers are connected, so that the liquid level height of each sub-chamber is consistent, and the inconsistent liquid level will not affect the atomization of the atomizer 320.

[0354] In some possible implementations, the stiffener 340 may extend to the bottom wall of the liquid storage cavity 301, and a communication opening may be provided at the end of the stiffener 340 that connects to the bottom wall of the liquid storage cavity 301 so that two adjacent sub-cavities can be connected.

[0355] In some embodiments of this application, at least one stiffener 340 is spaced apart from the top wall of the liquid storage cavity 301 along the height direction of the door body.

[0356] The top wall of the liquid storage cavity 301 may be the top plate of the front shell 317. At least one stiffener 340 is spaced apart from the top plate of the front shell 317.

[0357] In this embodiment, a gap is provided between the stiffener 340 and the top wall of the liquid storage cavity 301, so that the top of the two adjacent sub-cavities are connected, thereby allowing the gas at the top of the two adjacent sub-cavities to be connected, which is beneficial to balancing the gas pressure between the two adjacent sub-cavities, thereby making the liquid level between the two adjacent sub-cavities consistent.

[0358] In some possible implementations, at least one stiffener 340 may extend to the top wall of the liquid storage cavity 301, which may improve the reliability and stability of the connection between the stiffener 340 and the front shell 317.

[0359] Continue to refer to Figure 19 and Figure 20 In some embodiments, the liquid storage cavity 301 includes two first cavity walls that are opposite to each other and spaced apart along the thickness direction of the door body.

[0360] One of the two first cavity walls is connected to one side of the stiffening plate 340 along the thickness direction of the door body, and the other of the two first cavity walls abuts against the other side of the stiffening plate 340 along the thickness direction of the door body.

[0361] In this embodiment, the stiffener 340 is fixed to one of the first cavity walls, thus fixing the stiffener 340 within the liquid storage cavity 301. The stiffener 340 abuts against the other first cavity wall, thereby dividing the liquid storage cavity 301 into at least two sub-cavities. The stiffener 340 only needs to be fixed to one of the first cavity walls, without needing to be connected to the other first cavity wall, which simplifies the structure within the liquid storage cavity 301.

[0362] In some possible implementations of this application, the rear cover plate 318 and the front side plate of the front shell 317 are respectively configured to form two first cavity walls of the liquid storage cavity 301.

[0363] In this case, at least one of the two sides of the stiffening plate 340 along the thickness direction of the door body is connected to the rear cover plate 318 on one side and abuts against the front side plate of the front shell 317 on the other side, so that two sub-cavities are formed on both sides of the stiffening plate 340 respectively.

[0364] Alternatively, at least one of the two sides of the stiffener 340 along the thickness direction of the door body 200 is connected to the front side plate of the front shell 317, and the other side abuts against the rear cover plate 318, so that two sub-cavities are formed on both sides of the stiffener 340 respectively.

[0365] In some embodiments, all stiffeners 340 are connected to one of the first cavity walls for easy processing and assembly.

[0366] In other embodiments, some of the stiffeners 340 are connected to one of the first cavity walls, and other stiffeners 340 are connected to the other first cavity wall. This allows for the provision of more stiffeners 340, and also improves the structural strength of the rear cover 318 and the front shell 317 respectively.

[0367] like Figure 19 As shown, a water inlet 304 is provided at the top of the liquid storage chamber 301 for adding water into the liquid storage chamber 301.

[0368] A water inlet plug 3041 is installed inside the water inlet 304 to seal the water inlet 304 and prevent liquid from overflowing from the water inlet 304.

[0369] The water inlet plug 3041 is provided with a vent hole to balance the air pressure difference between the liquid storage chamber 301 and the outside atmosphere, preventing water in the liquid storage chamber 301 from overflowing from the water inlet 304 during the opening and closing of the door. It can also prevent the formation of a low-pressure environment in the liquid storage chamber 301 after the liquid in the liquid storage chamber 301 is consumed by the atomizer 320, which would be detrimental to the flow of the liquid.

[0370] In some embodiments of this application, a water inlet structure 350 is provided in the liquid storage cavity 301, and the water inlet structure 350 is configured to form a water inlet channel 351; the water inlet end of the water inlet channel 351 is opposite to the water inlet 304, and the water outlet end of the water inlet channel 351 is connected to the liquid storage cavity 301.

[0371] Thus, by providing a water inlet structure 350 within the liquid storage chamber 301, which forms a water inlet channel 351, water can not only enter the liquid storage chamber 301, but the water inlet channel 351 also increases the overflow resistance between the liquid storage chamber 301 and the water inlet 304, reducing the possibility of liquid overflowing from the liquid storage chamber 301 when the door is opened or closed. Furthermore, the water inlet structure 350 also helps to reduce liquid sloshing.

[0372] In some embodiments, the water inlet channel 351 may be curved to increase the resistance to liquid overflowing through the water inlet channel 351 and the water inlet 304, thereby improving the overflow prevention performance of the water inlet 304.

[0373] In other embodiments, the water inlet channel 351 can be a straight channel, and by setting a barrier structure in the straight channel, the resistance to liquid overflowing outward through the water inlet channel 351 and the water inlet 304 can be increased.

[0374] Continue to refer to Figure 20 In some embodiments, the water inlet structure 350 includes a rib 352, which is connected to the side wall of the water inlet channel 351 and is located within the water inlet channel 351.

[0375] The end of the reinforcing rib 352 that faces away from the side wall of the water inlet channel 351 is inclined in a direction away from the water inlet 304; Figure 20 In the middle, the end of the rib 352 that is away from the side wall of the water inlet channel 351 is inclined downward.

[0376] At least a portion of the projection of the reinforcing rib 352 onto the first plane lies within the water inlet 304; wherein the first plane is perpendicular to the depth direction of the water inlet 304. When the door is closed, the depth direction of the water inlet 304 is parallel to the height direction of the door.

[0377] When the water inlet 304 is located on the top wall of the water storage cavity, the first plane can be a horizontal plane. The horizontal plane is the plane determined by the width and thickness directions of the door body 200.

[0378] In some embodiments of this application, the water inlet structure 350 increases the resistance to water overflow by providing ribs 352 on the side wall of the water inlet channel 351, such that at least a portion of the ribs 352 is opposite to the water inlet 304, thereby preventing liquid from overflowing from the storage chamber 301. Since the end of the rib 352 facing away from the side wall of the water inlet channel 351 is inclined downward, the resistance during water injection is small and has little impact on water injection.

[0379] like Figure 20 As shown, in some embodiments of this application, multiple reinforcing bars 352 are provided, and the multiple reinforcing bars 352 are arranged at intervals along the extension direction of the water inlet channel 351.

[0380] As the water inlet channel 351 extends along the height direction of the door body 200, multiple ribs 352 are arranged at intervals along the height direction of the door body 200.

[0381] This embodiment of the application improves the problem of liquid overflow when the humidification module 300 is opened and closed by setting multiple ribs 352 to increase the resistance of liquid overflow from the liquid storage chamber 301 through the water inlet 304.

[0382] In some embodiments of this application, the water inlet structure 350 further includes: two channel side plates 353; the two channel side plates 353 are arranged at intervals along the width direction of the door.

[0383] The two walls of the liquid storage cavity 301 along the thickness direction of the door body are the first cavity walls, and the two channel side plates 353 together with the two first cavity walls form the water inlet channel 351.

[0384] Among them, the two channel side plates 353, together with the rear cover plate 318 and the front side plate of the front shell 317, form a water inlet channel 351.

[0385] Both channel side panels 353 can be connected to the rear cover plate 318, and both channel side panels 353 abut against the front side plate; alternatively, both channel side panels 353 can be connected to the front side plate, and both channel side panels 353 abut against the rear cover plate 318. This connection of the two channel side panels 353 to either the rear cover plate 318 or the front side plate simplifies the connection structure of the channel side panels 353.

[0386] The reinforcing bar 352 is connected to the channel side plate 353, and the reinforcing bar 352 is located on the side of the two channel side plates 353 facing each other.

[0387] This embodiment of the application simplifies the structure of the liquid storage cavity 301 by providing two channel side plates 353 within the liquid storage cavity 301. These side plates, together with the two cavity walls along the thickness direction of the cavity, form a water inlet channel 351. Furthermore, the two channel side plates 353 also help reduce liquid sloshing.

[0388] In some embodiments of this application, all the ribs 352 are respectively provided on the side of the two channel side plates 353 facing each other, and the ribs 352 on the two channel side plates 353 are spaced apart along the width direction of the door body 200.

[0389] In this embodiment, by providing ribs 352 on the two channel side plates 353 respectively, the resistance to liquid overflowing through the water inlet 304 is further increased, reducing the possibility of water overflow from the water inlet 304. Moreover, the ribs 352 on the two channel side plates 353 are spaced apart, which helps to reduce water injection resistance and ensures smooth water injection and water injection rate.

[0390] In this embodiment, the humidification module 300 rotates relative to the door 200 to add water. In some embodiments, a damping shaft can be provided between the humidification module 300 and the door 200, allowing the humidification module 300 to rotate relative to the door 200 and to rotate to a preset angle; and fixing the humidification module 300 relative to the door 200 after water is added.

[0391] In other embodiments, the humidification module 300 is fixed to or unlocked from the door 200 by a latch structure, so that the humidification module 300 can rotate relative to the door 200.

[0392] like Figure 17 and Figure 21 As shown, the humidification module 300 may include: a humidification body 31, configured to humidify the refrigerator compartment; a water inlet is disposed on the humidification body 31. The humidification body 31 is rotatably mounted on the door. The humidification body 31 may include a shell assembly and internal structures such as an atomizer.

[0393] The humidification module 300 may also include a locking structure 32, which is movably connected to the humidification body 31.

[0394] The locking structure 32 has a locked position and an unlocked position, and the locking structure 32 is configured to move relative to the humidifying body 31 between the locked position and the unlocked position.

[0395] The locking position is the position when the latch structure 32 is fixedly connected to the mating structure 250 provided on the door body 200; when the latch structure 32 is in the locking position, the humidification module 300 is fixed relative to the door body 200.

[0396] The unlocked position is the position where the latch structure 32 disengages from the mating structure 250; when the latch structure 32 is in the unlocked position, the humidification module 300 can rotate relative to the door 200.

[0397] The latching structure 32 can move relative to the humidifying body 31 along the thickness direction of the door body 200, allowing it to move between a locked position and an unlocked position. Alternatively, the latching structure 32 can slide relative to the humidifying body 31 in a certain direction, allowing it to move between a locked position and an unlocked position. Or, the latching structure 32 can rotate relative to the humidifying body 31, allowing it to move between a locked position and an unlocked position. For example, the rotation angle between the locked and unlocked positions of the latching structure 32 can be 90° for convenient operation.

[0398] In this embodiment, by providing a locking structure 32 on the humidifying body 31 and a cooperating structure 250 on the door 200, the humidifying body 31 is fixed relative to the door 200 and cannot rotate, which helps to ensure the stability of the humidifying module 300 relative to the door 200. When the locking structure 32 moves to the unlocked position, the locking structure 32 disengages from the cooperating structure 250, allowing the humidifying body 31 to rotate relative to the door 200. This allows the humidifying body 31 to rotate relative to the door 200 to the water filling position, whereby water is added to the liquid storage chamber 301 inside the humidifying body 31.

[0399] Reference Figure 19 In some embodiments of this application, a receiving portion 370 is formed on the humidifying body 31 for mounting the locking structure 32.

[0400] In some embodiments, a third partition plate 3173 is provided inside the liquid storage cavity 301, and the third partition plate 3173 and the cavity wall of the liquid storage cavity 301 together enclose and form a receiving portion 370.

[0401] The third partition plate 3173 can be connected to the front side plate of the front shell 317, and the third partition plate 3173 abuts against the rear cover plate 318, so that the third partition plate 3173, the rear cover plate 318, and the front side plate together enclose the receiving part 370.

[0402] The receiving portion 370 has an opening so that at least a portion of the locking structure 32 is exposed through the opening to the outer surface of the humidification module 300 for easy user operation.

[0403] In some embodiments, the latching structure 32 includes an operating member 321, a portion of which is installed in the receiving portion 370, and the other portion is exposed on the side of the humidifying body 31 away from the door 200, for easy operation by the user.

[0404] The operating element 321 is configured to move relative to the humidifying body 31, and in some embodiments of this application, the operating element 321 rotates relative to the humidifying body 31.

[0405] The locking structure 32 may further include a locking member 322, which is located within the receiving portion 370 and is fixedly connected to the operating member 321. The operating member 321 drives the locking member 322 to move between a locked position and an unlocked position.

[0406] In the locked position, the locking member 322 is connected to the mating structure 250; in the unlocked position, the locking member 322 is disengaged from the mating structure 250.

[0407] In some possible implementations of this application, the operating member 321 may include a rotating operating part 3211, which is located outside the receiving part 370.

[0408] The operating member 321 may include a column portion 3212, which is connected to the rotary operating member 3211 and is located within the receiving portion 370. The locking member 322 is connected to the end of the column portion 3212 that is away from the rotary operating member 3211.

[0409] The operating element 321 may include an engaging protrusion 3213, which is disposed on the side of the post portion 3212. Exemplarily, two engaging protrusions 3213 may be provided, and the two engaging protrusions 3213 are arranged circumferentially around the post portion 3212.

[0410] In some embodiments, an annular limiting portion 371 is provided within the receiving portion 370. One end of the annular limiting portion 371 facing away from the door body 200 is recessed relative to the outer surface of the humidifying body 31 and abuts against the rotating operating portion 3211. The column portion 3212 engages with the central hole of the annular limiting portion 371. The other end of the annular limiting portion 371 is configured to form an arc-shaped engaging groove 372, so that the engaging protrusion 3213 engages with the engaging groove 372, thereby restricting the operating member 321 along the thickness direction of the door body onto the humidifying body 31. The operating member 321 is configured to rotate relative to the receiving portion 370, and the engaging protrusion 3213 rotates along the engaging groove 372.

[0411] Limiting platforms 373 are provided at both ends of the engaging groove 372 to limit the rotation position of the operating member 321, so that the operating member 321 can rotate between the locked position and the unlocked position.

[0412] A protrusion 374 is provided within the engagement groove 372, and the protrusion 374 is close to the limiting platform 373 at the locking position. As the engagement protrusion 3213 rotates along the engagement groove 372 to the locking position, the engagement protrusion 3213 collides with the protrusion 374, producing a "click" tactile sensation to indicate to the user that the humidification module is locked in place, thereby improving the reliability of the locking structure 32.

[0413] In this embodiment, the latching structure 32 is equipped with an operating member 321, with a portion of the operating member 321 exposed on the side of the humidifying body 31 facing away from the door 200, facilitating user operation. The latching structure 32 is fixedly connected to the operating member 321 by a locking member 322, and moves between the locked and unlocked positions under the action of the operating member 321, thereby locking and unlocking the humidifying module 300.

[0414] This application embodiment uses a mechanical locking structure 32 to lock and unlock the humidification module 300. The structure is simple and easy to operate. Compared with electric unlocking and locking, the locking structure 32 of this application embodiment has a lower cost.

[0415] Combination Figure 19 The top surface of the humidifying body 31 is provided with a locking opening 3701, which is connected to the receiving part 370.

[0416] For example, the top plate of the front housing 317 is provided with a locking opening 3701.

[0417] Combination Figure 21 The door body 200 is constructed to form a top sidewall 224 opposite to the top surface of the humidifier body 31, and an installation groove is formed on the inner liner 220 for installing the humidifier body 31. The top sidewall 224 can be the top wall of the installation groove.

[0418] A mating groove 2241 is formed on the top sidewall 224, and the mating groove 2241 opens toward the top surface of the humidifying body 31; wherein, the mating groove 2241 forms a mating structure 250.

[0419] In the locked position, the locking element 322 extends into the mating groove 2241 through the locking opening 3701;

[0420] In the unlocked position, the locking member 322 returns to the receiving portion 370 through the locking opening 3701.

[0421] Combination Figure 19 and Figure 20 In some embodiments of this application, the third partition plate 3173 includes an arc-shaped plate 3174, a first connecting plate 3175, and a second connecting plate 3176. The arc-shaped plate 3174 surrounds a portion of the outer side of the annular limiting portion. One end of the first connecting plate 3175 and the second connecting plate 3176 are connected to both ends of the arc-shaped plate 3174; the other ends of the first connecting plate 3175 and the second connecting plate 3176 are respectively connected to the top wall of the front shell portion 317 and are respectively located on both sides of the locking opening 3701.

[0422] Thus, the third partition plate 3173, together with the arc plate 3174, the first connecting plate 3175 and the second connecting plate 3176, forms a receiving part 370, which can not only install the locking structure 32, but also provide space for the rotation of the locking structure 32.

[0423] In some embodiments of this application, by providing a mating groove 2241 on the door body, the locking member 322 extends into the mating groove 2241 through the locking opening 3701, restricting the position of the humidifying body 31 along the thickness direction of the door body, thereby fixing the humidifying body 31 to the door body; the locking member 322 returns to the receiving part 370 through the locking opening 3701, the limitation between the humidifying body 31 and the door body is released, thereby allowing the humidifying body 31 to rotate relative to the door body.

[0424] In other embodiments of this application, reference is made to Figures 22 to 24 The humidifier body 31 has a mating opening 3702 on the back side 314 facing the door 200, and the mating opening 3702 is connected to the receiving part 370.

[0425] The opening 3702 can be an opening provided on the rear cover plate 318.

[0426] Combination Figure 23 and Figure 24 The mating structure 250 includes a limiting member 251, which is fixed to the inner door liner 220 of the door body. The limiting member 251 is configured to engage with the locking member 322 through the mating opening 3702.

[0427] The limiting member 251 can be fixed to the inner door liner 220. The inner door liner 220 is provided with an installation port. Part of the limiting member 251 is installed on the side of the inner door liner 220 facing the outer door shell, and part of the limiting member 251 extends into the side of the inner door liner 220 facing the humidifying body 31 through the installation port.

[0428] One of the limiting member 251 and the locking member 322 is provided with a limiting protrusion 2512, and the other is provided with a limiting groove 3214;

[0429] In the locked position, the limiting protrusion 2512 engages with the limiting groove 3214;

[0430] In the unlocked position, the limiting protrusion 2512 disengages from the limiting groove 3214.

[0431] Exemplarily, the post portion 3212 of the operating member 321 is provided with a slot 3215, and a limiting groove 3214 is provided on the post portion 3212. The limiting groove 3214 is located within the slot 3215, and one end of the limiting groove 3214 communicates with the slot 3215. A locking protrusion 3213 is provided on the outer surface of the post portion 3212. The limiting groove 3214 can be an arc-shaped groove extending circumferentially along the post portion 3212. The post portion 3212 of the operating member 321 forms a locking member 322.

[0432] The limiting component 251 includes a mounting plate 2513, a connecting post 2511, and a limiting protrusion 2512. The mounting plate 2513 is fixed to the inner door liner 220, and the mounting plate 2513 is located on the side of the inner door liner 220 facing the outer door shell. The connecting post 2511 is fixedly connected to the mounting plate 2513. The limiting protrusion 2512 is disposed on the side of the connecting post 2511, and both the connecting post 2511 and the limiting protrusion 2512 are located on the side of the inner door liner 220 facing the humidifying body 31. The connecting post 2511 mates with the slot 3215, and the limiting protrusion 2512 mates with the limiting groove 3214.

[0433] When the operating component 321 rotates to engage with the limiting groove 3214 and the limiting protrusion 2512, the locking structure 32 is in the locked position. The engagement of the limiting groove 3214 and the limiting protrusion 2512 fixes the humidifying body 31 relative to the door 200. When the operating component 321 rotates to disengage the limiting protrusion 2512 through the opening of the limiting groove 3214, the locking structure 32 is in the unlocked position, and the limiting between the limiting groove 3214 and the limiting protrusion 2512 is released, allowing the humidifying body 31 to rotate relative to the door 200.

[0434] In some embodiments, two limiting protrusions 2512 may be provided, and the two limiting protrusions 2512 are spaced apart along the circumferential direction of the connecting post 2511; correspondingly, two limiting grooves 3214 are provided, such an arrangement can provide stability for the engagement of the limiting member 251 and the locking member 322.

[0435] In this embodiment, the mating structure 250 and the latching structure 32 of the door 200 are arranged along the thickness direction of the door 200, which is suitable for refrigerators with thin door 200.

[0436] Continue to refer to Figure 24 In some embodiments, the locking structure can be disposed below the water inlet 304, so that the third partition plate 3173 can increase the resistance to liquid overflow from the water inlet 304 in the liquid storage chamber 301. The water inlet structure 350 is located between the third partition plate 3173 and the water inlet 304.

[0437] In yet other embodiments, reference is made to Figures 25 to 27 The door can also be equipped with a lock detection switch 270 and a trigger 260.

[0438] When the locking member 322 is connected to the mating structure 250, the locking member 322 abuts against the trigger member 260, causing the trigger member 260 to deform, thereby triggering the locking detection switch 270 to send out a first signal;

[0439] When the door closes the refrigerator compartment and the locking element 322 is not connected to the mating structure 250, the locking detection switch 270 is configured to send a second signal;

[0440] The first signal indicates that the locking member 322 is connected to the mating structure 250; the second signal indicates that the locking member 322 is not connected to the mating structure 250.

[0441] In some embodiments of this application, a locking detection switch 270 and a trigger 260 are provided on the door to detect the locking state of the latch structure 32, so as to prevent the locking member 322 from not engaging with the mating structure 250 when the door is closed, which would cause the humidifying body 31 to rotate relative to the door and affect the stability of the humidifying body 31.

[0442] In some embodiments, the limiting member 251 of the mating structure 250 is provided with an abutment opening 2514. A portion of the trigger member 260 extends into the receiving portion 370 through the abutment opening 2514.

[0443] The trigger 260 is located on the side of the inner door liner facing the outer door liner and is in contact with the sensing part 271 of the lock detection switch 270.

[0444] When the locking member 322 and the limiting member 251 are engaged, the portion of the locking member 322 and the portion of the trigger member 260 that extends into the receiving portion 370 abut against each other, thereby causing the trigger member 260 to trigger the locking detection switch 270 to send a first signal through the sensing portion 271 of the locking detection switch 270.

[0445] When the door of the refrigerator compartment is closed and the locking member 322 does not engage with the limiting member 251, the trigger member 260 does not trigger the sensing part 271 of the locking detection switch 270, causing the locking detection switch 270 to send a second signal indicating that the humidifying body 31 is not locked to the door 200.

[0446] This application does not limit the specific structure of the locking detection switch 270; the locking detection switch 270 can be a micro switch or the like. The sensing part of the locking detection switch 270 can be an elastic element.

[0447] Combination Figure 26 and Figure 27 In some embodiments, the limiting member 251 is provided with a mounting hole 2515. The mounting hole 2515 may be provided on the mounting plate 2513 and the connecting post 2511.

[0448] In some embodiments of this application, reference is made to Figure 25 and Figure 27 The trigger 260 includes a mating part 261 and an abutting part 262. The mating part 261 is installed in the mounting hole 2515; the abutting part 262 is connected to the side of the mating part 261, and a portion of the abutting part 262 extends into the receiving part 370 through the abutting opening 2514.

[0449] In this embodiment of the application, the trigger 260 engages with the mounting hole 2515 via the mating part 261, thereby ensuring a stable engagement between the trigger 260 and the limiting member 251 and providing guidance for the movement of the trigger 260.

[0450] The mating part 261 may be provided with a mating hole 2611 so that the sensing part 271 of the locking detection switch 270 extends into the mating hole 2611, ensuring the stability of the mating between the trigger 260 and the sensing part 271 of the locking detection switch 270.

[0451] In some implementations, when the operating member 321 drives the locking member 322 to rotate to the locked position, the locking member 322 engages with the limiting member 251 while simultaneously abutting against the trigger member 260, pushing the trigger member 260 relative to the limiting member 251 toward the locking detection switch 270, so that the trigger member 260 abuts against the sensing part 271 of the locking detection switch 270, thereby triggering the locking detection switch 270 to issue a first signal.

[0452] When the door is closed, but the latch structure 32 does not lock the humidifier body 31, the trigger 260 will not trigger the locking detection switch 270 because there is a gap between the locking member 322 and the trigger member 260, thus causing the locking detection switch 270 to send a second signal.

[0453] In this embodiment, by setting a locking detection switch 270 and a trigger 260 on the door 200, when the latching structure 32 locks the humidifying body 31 and the door 200, the locking member 322 triggers the locking detection switch 270 to send a first signal through the trigger 260; while when the door 200 is closed and the latching structure 32 does not lock the humidifying body 31 and the door 200, the locking detection switch 270 sends a second signal to remind the user that the humidifying module 300 is not locked, thereby improving the safety and reliability of the processing module.

[0454] During the humidification process of the humidification module 300, the liquid in the liquid storage chamber 301 is continuously consumed by the atomizer 320. If the liquid storage chamber 301 cannot be humidified in time, it will affect the humidification, and the atomizer 320 will not only be noisy when operating in the absence of water, but will also be easily damaged.

[0455] In some embodiments, a transparent plate 3101 is provided on the cavity wall of the liquid storage chamber 301 facing the refrigeration compartment 101, and the transparent plate 3101 extends along the height direction of the liquid storage chamber 301. In this way, the user can view the liquid level in the liquid storage chamber 301 through the transparent plate 3101, making it convenient for the user to obtain the liquid level in the liquid storage chamber 301 in a timely manner.

[0456] For example, refer to Figure 24 An opening is provided on the front side plate of the front shell 317, and the transparent plate 3101 is sealed to the front shell 317 and covers the opening.

[0457] In some embodiments of this application, combined with Figure 24 The humidification module 300 also forms a detection chamber 306, which is arranged side by side with the liquid storage chamber 301 along the width direction of the door 200; the bottom ends of the detection chamber 306 and the liquid storage chamber 301 are connected. Thus, the liquid levels in the detection chamber 306 and the liquid storage chamber 301 are the same, and the liquid level in the liquid storage chamber 301 can be determined by monitoring the liquid level in the detection chamber 306.

[0458] In some embodiments, a fourth partition plate 3177 is provided in the liquid storage chamber 301. The fourth partition plate 3177 extends along the height direction of the humidification module 300 to separate the liquid storage chamber 301 and the detection chamber 306. There is a gap between the bottom end of the fourth partition plate 3177 and the bottom wall of the liquid storage chamber 301 so that the detection chamber 306 and the liquid storage chamber 301 are connected.

[0459] In some embodiments, the fourth partition plate 3177 is connected to the front housing 317 of the humidification module 300, and there is a gap between the fourth partition plate 3177 and the rear cover plate 318, so that the detection chamber 306 and the liquid storage chamber 301 are in communication.

[0460] Reference Figures 28 to 30The humidification module 300 is equipped with a water shortage detection mechanism 380, which is configured to issue a water shortage signal when the liquid level in the liquid storage chamber 301 is lower than a set liquid level. The water shortage detection mechanism 380 includes, but is not limited to, liquid level monitoring mechanisms such as a liquid level gauge.

[0461] In some embodiments, the water shortage detection mechanism 380 includes a buoyancy member 381 located within the detection chamber 306 and floating along the detection chamber 306 according to the liquid level within the chamber. In this embodiment, the buoyancy member 381 floats along the height direction according to the liquid level within the detection chamber 306.

[0462] For example, the buoyancy component 381 can be foam, which has a low density and easily floats with the liquid level, thus improving detection accuracy. The buoyancy component 381 can also be a float, etc.

[0463] In some embodiments, combined with Figure 20 A support plate 3061 is provided at the bottom of the detection chamber 306, and there is a gap between the support plate 3061 and the bottom wall of the liquid storage chamber 301. Thus, when the buoyancy member 381 falls to the bottom of the detection chamber 306, the support plate 3061 can support the buoyancy member 381. When water is added to the liquid storage chamber 301, since the buoyancy member 381 is located above the bottom wall of the liquid storage chamber 301, the buoyancy member 381 can float under the action of buoyancy.

[0464] The water shortage detection mechanism 380 may further include a water shortage detection switch 382, ​​which is installed in the electrical cavity 305. The electrical cavity 305 is not connected to the detection cavity 306 to prevent liquid from entering the electrical cavity 305 and damaging electrical components such as the water shortage detection switch 382. In some embodiments, a third partition plate 3173 is disposed between the electrical cavity 305 and the detection cavity 306.

[0465] The buoyancy component 381 is configured to trigger the water shortage detection switch 382 to send a water shortage signal when the liquid level in the detection chamber 306 is lower than the set liquid level, so as to prompt the user to add water in time and ensure the normal operation of the humidification module 300.

[0466] Reference Figure 29 and Figure 30In some embodiments, the buoyancy member 381 can be non-transparent, such as a black buoyancy member 381. A detection opening 383 is provided on the fourth partition plate 3177 between the electrical cavity 305 and the detection cavity 306. The detection opening 383 is located on the side of the buoyancy member 381 in the direction of liquid level movement, for example, on the vertical side of the buoyancy member 381. A light-transmitting plate 384 is sealed and installed on the fourth partition plate 3177. The light-transmitting plate 384 can be a transparent glass plate. The water shortage detection switch 382 can be a photoelectric locking detection switch 270 installed in the electrical cavity 305, with the photoelectric locking detection switch 270 facing the detection port. When the liquid level in the detection cavity 306 is lower than the set liquid level, the buoyancy member 381 descends to face the detection opening 383. The light emitted by the photoelectric locking detection switch 270 is absorbed by the buoyancy member 381, and no feedback light is received, thus causing the photoelectric locking detection switch 270 to issue a water shortage signal. When the liquid level in the detection chamber 306 is higher than the set position, the buoyancy component 381 floats on the liquid level surface. The light emitted by the photoelectric locking detection switch 270 enters the detection chamber 306 through the locking detection switch 270 and is reflected back to the photoelectric locking detection switch 270. The photoelectric locking detection switch 270 detects the reflected light.

[0467] Reference Figure 31 and Figure 32 In some embodiments, the water shortage detection switch 382 can be a microswitch. The microswitch is located at the bottom of the buoyancy member 381. The trigger structure 385 of the microswitch extends into the bottom of the detection chamber 306. When the liquid level in the detection chamber 306 is lower than the set liquid level, the buoyancy member 381 is subjected to gravity, triggering the microswitch to close, causing the microswitch to send a water shortage signal. When the liquid level in the detection chamber 306 is higher than the set liquid level, the buoyancy force on the buoyancy member 381 is greater than the weight of the air, and the buoyancy member 381 moves away from the trigger structure 385.

[0468] During the opening and closing of the door 200, the liquid level in the storage chamber 301 inevitably fluctuates, which in turn causes fluctuations in the liquid level in the detection chamber 306. To ensure accurate water shortage detection, the water shortage detection mechanism 380 is configured to detect the liquid level in the storage chamber 301 after a set time following the opening and closing of the door 200. For example, the water shortage detection mechanism 380 is configured to detect the liquid level in the storage chamber 301 5 seconds after the door 200 has opened or closed.

[0469] In this embodiment, the humidification module 300 is equipped with a water shortage detection mechanism 380 to monitor the liquid level in the storage chamber 301, allowing for timely water replenishment to the storage chamber 301, reducing the possibility of the atomizer 320 burning out, and improving the safety of the humidification module 300. Furthermore, by constructing a detection chamber 306 communicating with the storage chamber 301 within the humidification module 300, the water level in the storage chamber 301 is determined using a buoyancy member 381 within the detection chamber 306. The detection chamber 306 can limit the buoyancy member 381, improving its stability and thus enhancing the accuracy of water shortage detection, reducing false alarms caused by liquid sloshing within the storage chamber 301.

[0470] In the above description, the humidification module 300 is used as an example. However, this is not limiting. For example, the functional module could also be a vacuum module, which can vacuum the storage bag. Furthermore, the functional module could also be a deodorizing module, which can deodorize the refrigerator compartment.

[0471] Based on the above description, the functional modules of this application embodiment are installed on the door and do not occupy the storage space of the cold storage compartment.

[0472] The projection of the door shelf along the height of the door covers the functional module, so that the functional module does not protrude from the door shelf along the thickness of the door, thus avoiding interference between the functional module and the internal components of the cold storage compartment when the door is closed.

[0473] The functional modules are embedded in the mounting groove of the door, which reduces the volume of the functional modules protruding from the inner surface of the door, allowing the functional modules to be installed in a concealed manner, which improves the aesthetic appearance of the inner side of the door; it also avoids interference with the drawers installed in the refrigerator.

[0474] The functional module is rotatably connected to the door and is configured to be detachable from the door after rotation. This allows at least a portion of the functional module to be exposed from the mounting slot after rotation relative to the door, thereby moving at least a portion of the functional module away from the door. This expands the detachable operation space of the functional module. The rotation operation of the functional module is time-saving and labor-saving, which helps to improve the convenience of assembling and disassembling the functional module.
