Description

Technical Field

[0001] The embodiments of the present application relate to household appliance technology, and more specifically, to a refrigerator. Background Art

[0002] In the related art, an air-cooled refrigerator uses a fan to send cold air to a refrigerating compartment and a freezing compartment through an air duct. The temperature of the refrigerating compartment is above zero degrees, and the temperature of the freezing compartment is below zero degrees, so as to store separately according to different storage temperatures.

[0003] Although the refrigerator compartment and the cold storage compartment have a large temperature adjustment range, the ability to change the air volume is not enough to adjust the temperature from below zero to above zero in a large range, which limits the temperature adjustment ability of the refrigerator and is inconvenient to use. Utility Model Content

[0004] The embodiment of the present application provides a refrigerator which can adjust the temperature of a freezer compartment to be greater than 0° C. to refrigerate items.

[0005] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0006] A box body, which is structured to form a refrigerating compartment and a freezing compartment;

[0007] A freezing air duct structure is installed in the freezing compartment, and the freezing air duct structure is configured to form a freezing air duct, a freezing air inlet, and a refrigeration connection port, the freezing air inlet is connected to the freezing air duct and the freezing compartment, and the refrigeration connection port is connected to the freezing air duct and the refrigeration compartment;

[0009] A sliding member is installed on the freezing air duct structure, and a portion of the sliding member extends into the freezing compartment; the sliding member is configured to slide along a first direction;

[0010] A shielding member installed in the freezing air duct; the shielding member is configured to shield at least a portion of the freezing air inlet or to be staggered with the freezing air inlet;

[0011] A linkage mechanism, one end of which is connected to the shielding member;

[0012] When the sliding member is configured to slide along a first direction, the blocking member is driven to slide along a second direction through the linkage mechanism to adjust the size of the freezing air inlet; wherein the first direction and the second direction have an angle.

[0013] In some embodiments of the present application, the adjustment assembly of the refrigerator includes a sliding member, a shielding member, and a linkage mechanism, and a portion of the sliding member extends into the freezer compartment, so that the user can slide the sliding member in a first direction by operating the sliding member, and drive the shielding member to move in a second direction through the linkage mechanism to shield at least a portion of the freezing air inlet, thereby reducing the air intake area of ​​the freezing air inlet, reducing the air intake volume of the freezing compartment, and making the temperature of the freezing compartment greater than 0°C, so that the freezing compartment has the refrigeration function of the refrigeration compartment, and expanding the refrigeration space. In addition, the freezing air inlet is usually arranged at the top of the freezing air duct structure, and there is an angle between the moving direction of the sliding member and the moving direction of the shielding member, which can make the setting position of the sliding member and the structural setting of the linkage mechanism more flexible.

[0014] In some embodiments of the present application, the sliding member and the other end of the linkage mechanism are spaced apart along the first direction; when the sliding member is configured to slide along the first direction until it abuts against the other end of the linkage mechanism, the linkage mechanism is driven to move.

[0015] In the embodiment of the present application, the sliding member and the linkage mechanism are spaced apart, which is conducive to reducing the difficulty of assembling the adjustment component; and the sliding member and the linkage mechanism are abutted to drive the linkage mechanism to move, so that the shielding member shields part of the freezing air inlet, and there is no need to adjust the size of the freezing air inlet, and only shield the freezing air inlet to achieve the conversion from freezing to refrigeration. When the sliding member also has the function of adjusting the air volume of the refrigerating compartment, when the sliding member adjusts the air volume of the refrigerating compartment, the sliding member is disengaged from the linkage mechanism to avoid shielding the freezing air inlet.

DETAILED DESCRIPTION

[0075] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0076] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0077] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0078] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0079] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0080] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0081] When the seasons change or during a certain period of time, users have a lot of specific storage needs. For example, in hotter areas or times, more refrigeration space is needed to refrigerate beverages, water or fruits; for example, in certain festivals, more freezing space is needed to freeze meat. However, the storage space of the freezing and refrigerating compartments of existing refrigerators is relatively fixed, and the temperature adjustment capacity of the freezing and refrigerating compartments is not enough to achieve a wide range of temperature adjustment from below zero to above zero, which cannot meet the storage needs of users.

[0082] In some refrigerator products, electric dampers are installed at the air outlets of the freezer and refrigerator compartments. By controlling the opening size of the electric dampers, the temperature of the freezer and refrigerator compartments can be adjusted, and the sub-zero freezer compartment can be converted into a refrigerator compartment. However, the cost is high, the control is complex, and the reliability is poor; especially for single-system refrigerators, the practicality is poor.

[0083] In some single-system air-cooled refrigerators, a mechanical damper is used to control the air volume in the compartment, and a temperature sensor is installed in the refrigeration compartment to control the start and stop of the compressor. The temperature of the refrigeration compartment is above 0°C, and the temperature of the freezer compartment is around -18°C.

[0084] The freezing chamber and the refrigerating chamber are respectively provided with air ducts, the freezing air duct and the refrigerating air duct are connected, and a manual damper is provided at the connection between the freezing air duct and the refrigerating air duct. The size of the air outlet can be changed by operating the manual damper, thereby changing the air volume entering the refrigerating air duct.

[0085] The low-temperature air generated by the evaporator enters the freezing air duct under the action of the freezing fan. Part of the cold air enters the freezing room, and the other part of the air enters the cold storage room through the air outlet.

[0086] When the manual damper is operated to make the air outlet as small as possible, the air supply volume of the refrigerated compartment is the smallest, and the time required for the indoor temperature of the refrigerated compartment to reach the shutdown temperature of the compressor is the longest; at this time, the air supply volume of the freezer compartment is the largest, the refrigeration time is the longest, and the temperature of the freezer compartment can generally reach -24°C; conversely, when the manual damper is operated to make the air outlet as large as possible, the air supply volume of the refrigerated compartment is the largest, and the time required for the indoor temperature of the refrigerated compartment to reach the shutdown temperature of the compressor is the shortest; at this time, the air supply volume of the freezer compartment is the smallest, the refrigeration time is the shortest, and the temperature of the freezer compartment can generally reach -12°C.

[0087] Therefore, due to the limitation of the air duct structure, the temperature of the freezer compartment cannot reach above 0°C, and the freezer compartment cannot be converted into a refrigerated compartment.

[0088] In view of this, the researchers of this application abandoned the intelligently operated electric damper and adopted a mechanical manual damper. By reducing the air volume at the air outlet of the freezer compartment to make it equivalent to the air supply volume of the refrigerator compartment, when the refrigerator compartment reaches the temperature shutdown point, the temperature of the freezer compartment is higher than zero degrees, thereby realizing the conversion from the freezer compartment to the refrigerator compartment. The structure is simple and reliable.

[0089] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0090] First of all, it should be noted that in the embodiment of the present application, when the user faces the door of the refrigerator, the width direction of the refrigerator, that is, the left-right direction, corresponds to the X-axis direction in the accompanying drawings; the depth direction of the refrigerator, that is, the depth direction of the compartment, is the front-to-back direction, which corresponds to the Y-axis direction in the accompanying drawings; the height direction of the refrigerator, that is, the up-and-down direction, corresponds to the Z-axis direction in the accompanying drawings.

[0091] like Figure 1 and Figure 2 As shown, the refrigerator of some embodiments of the present application includes a cabinet 100, which is constructed to form a freezer compartment 101 with an opening on the front side, and the storage temperature of the freezer compartment 101 is lower than 0°C, for example, -18°C; the cabinet 100 is also constructed to form a refrigeration compartment 102 with an opening on the front side, and the storage temperature of the refrigeration compartment 102 is higher than 0°C, for example, 10°C.

[0092] In some embodiments, the freezing compartment 101 is located above the refrigerating compartment 102. This is not restrictive, and in some embodiments, the freezing compartment 101 is located below the refrigerating compartment 102.

[0093] The refrigerator of some embodiments of the present application further includes a door body, which is rotatably mounted on the cabinet 100 to open or close the freezing compartment 101 and the refrigerating compartment 102. Exemplarily, the door body is rotatably mounted on the cabinet 100 via a hinge.

[0094] In some embodiments, at least two doors are provided, one of which is configured to open or close the freezer compartment 101, and the other is configured to open or close the refrigerator compartment 102, so that the freezer compartment 101 and the refrigerator compartment 102 are separated to avoid affecting the storage temperature.

[0095] In some embodiments, the refrigerator further includes a refrigeration system configured to control the refrigerant to cool the freezing compartment 101 and the refrigerating compartment 102 .

[0096] In some embodiments, the refrigeration system may include an evaporator 120, a compressor 130, a condenser, and a throttling element. The compressor 130 is used to compress the refrigerant vapor to generate high-temperature and high-pressure vapor, and transport the refrigerant vapor to the condenser. The condenser is used to liquefy the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant cold liquid, and transport the refrigerant cold liquid to the throttling element. After the throttling element throttles and depressurizes the refrigerant cold liquid, the high-pressure and low-temperature liquid is converted into a low-pressure and low-temperature refrigerant, and the low-pressure and low-temperature refrigerant is transported to the evaporator 120. After receiving the low-pressure and low-temperature refrigerant, the evaporator 120 makes it boil under isobaric conditions, absorbs heat and vaporizes, so as to reduce the temperature in the storage room.

[0097] The evaporator 120 may be disposed at the back of the freezing compartment 101 to facilitate cold air to enter the freezing compartment 101 and help the freezing compartment 101 reach a set freezing storage temperature.

[0098] The compressor 130 may be installed in a compressor compartment at the rear bottom of the housing 100, which is beneficial for maintaining the stability of the refrigerator structure and for transmitting the noise of the compressor 130 to the ground.

[0099] Combine again Figure 1 and Figure 2 In some embodiments, the refrigerator includes a refrigerating air duct structure 110, which is installed in the refrigerating compartment 102 and located at the rear of the refrigerating compartment 102. The refrigerating air duct structure 110 is configured to introduce cold air generated by the evaporator 120 into the refrigerating compartment 102.

[0100] In some embodiments, a refrigeration air duct, a refrigeration air inlet 111 and a refrigeration return air vent are formed in the refrigeration air duct structure 110. The refrigeration air inlet 111 is connected to the refrigeration air duct and the refrigeration compartment 102 respectively, and the refrigeration return air vent is connected to the return air duct and the refrigeration compartment 102 respectively. The refrigeration air inlet 111 can be arranged at the top of the refrigeration compartment 102, and the refrigeration return air vent can be arranged at the bottom of the refrigeration compartment 102. In this way, the cold air generated by the evaporator 120 enters the refrigeration compartment 102 through the refrigeration air inlet 111, and the air with a higher temperature in the refrigeration compartment 102 returns to the chamber where the evaporator 120 is located through the refrigeration return air vent and the return air duct for heat exchange, and this cycle is repeated, so that the storage temperature of the refrigeration compartment 102 reaches the set temperature range.

[0101] Combination Figures 1 to 3 In some embodiments of the present application, the refrigerator further includes a freezing air duct structure 200 installed in the freezing compartment 101. The freezing air duct structure 200 is configured to introduce the cold air generated by the evaporator 120 into the freezing compartment 101.

[0102] like Figure 3 As shown, the freezing air duct structure 200 is constructed to form a fan air inlet 205, and the fan air inlet 205 is located on the back of the freezing air duct structure 200, so as to be conveniently connected to the chamber where the evaporator 120 is located.

[0103] The freezing air duct structure 200 is also configured to form a freezing return air port 204, which connects the return air duct and the freezing chamber 101, and the return air duct is connected to the chamber where the evaporator 120 is located. In this way, the air in the freezing chamber 101 can be connected to the chamber where the evaporator 120 is located via the freezing return air port 204 and the return air duct.

[0104] The freezing air duct structure 200 is also configured to form a refrigeration communication port 203, which is connected to the refrigeration air duct, so that cold air can enter the refrigeration air duct. In other words, a part of the cold air generated by the evaporator 120 enters the freezing compartment 101 through the freezing air duct structure 200, and another part enters the refrigeration air duct through the refrigeration communication port 203, thereby refrigerating the refrigeration compartment 102.

[0105] The opening direction of the refrigeration communication port 203 is downward, so as to facilitate connection with the refrigeration air duct structure 110 .

[0106] Combination Figure 4 In some embodiments, the freezing air duct structure 200 is further configured to form a freezing air inlet 202 , which is connected to the freezing compartment 101 so that the cold air in the freezing air duct structure 200 can enter the freezing compartment 101 .

[0107] In some embodiments, the freezing air inlet 202 is located above the front side of the freezing air duct structure 200, and the freezing return air outlet 204 is located below the front side of the freezing air duct structure 200. The cold air with higher density tends to move downward, so that the air with higher temperature is discharged from the freezing compartment 101 through the freezing return air outlet 204.

[0108] Combination Figure 5 In some embodiments, the freezing air duct structure 200 is further configured to form a freezing air duct 201, which is in communication with the fan air inlet 205, so that the cold air generated by the evaporator 120 can enter the freezing air duct 201 through the fan air inlet 205. The freezing air duct 201 is also in communication with the freezing air inlet 202, so that the cold air in the freezing air duct 201 can enter the freezing compartment 101 through the freezing air inlet 202. The freezing air duct 201 is also in communication with the refrigeration connection port 203, so that the cold air in the freezing air duct 201 enters the refrigeration air duct through the refrigeration connection port 203.

[0109] Continue to refer to Figure 5 In some embodiments, the freezing air duct structure 200 includes a first cover plate 210 , which serves as a front cover plate of the freezing air duct structure 200 , and a freezing air inlet 202 and a freezing air return port 204 are formed on the first cover plate 210 .

[0110] In some embodiments, the freezing air duct structure 200 further includes a second cover plate 220, which is relatively arranged along the thickness direction (corresponding to the Y-axis direction in the figure) of the freezing air duct structure 200. The second cover plate 220 serves as a rear cover plate of the freezing air duct structure 200, and a fan air inlet 205 is arranged on the second cover plate 220. The freezing air duct 201 is located between the first cover plate 210 and the second cover plate 220.

[0111] In some embodiments, the freezing air duct structure 200 further includes an air duct plate 230, which may be a foam plate, and is sandwiched between the first cover plate 210 and the second cover plate 220, and a freezing air duct 201 is formed on the air duct plate 230. The air duct plate 230 can not only support the first cover plate 210 and the second cover plate 220 to prevent the first cover plate 210 and the second cover plate 220 from deforming and affecting the shape of the freezing air duct 201, but also the freezing air duct 201 formed by the air duct plate 230 is more flexible in shape and can also keep the cold air warm.

[0112] In some embodiments, the freezing air duct structure 200 further includes a freezing fan 240, which is installed in the freezing air duct 201 and located between the freezing air inlet 202 and the refrigerating connecting port 203, and the freezing fan 240 is opposite to the fan air inlet 205. Thus, under the action of the freezing fan 240, the cold air generated by the evaporator enters the freezing air duct 201 through the fan air inlet 205; a part of the cold air in the freezing air duct 201 enters the freezing compartment 101 through the freezing air inlet 202, and another part enters the refrigerating air duct through the refrigerating connecting port 203, and then enters the refrigerating compartment.

[0113] The refrigeration fan 240 may be fixed to the first cover plate 210 and / or the second cover plate 220 , and the fixing methods include but are not limited to snap connection and screw connection.

[0114] In the embodiment of the present application, the cold air generated by the evaporator 120 enters the refrigerating air duct via the freezing air duct 201. The refrigerating air duct does not need to extend to the back side of the freezing compartment 101, which helps to reduce the installation space occupied by the air duct and makes the refrigerator structure more compact.

[0115] In some embodiments, the refrigerator further includes an adjustment component 300, which is installed on the freezing air duct structure 200, part of the adjustment component 300 is located inside the freezing air duct structure 200, and part of the adjustment component 300 is located in the freezing compartment 101, so that the user can operate the adjustment component 300 conveniently.

[0116] In some embodiments of the present application, a portion of the first end of the adjusting component 300 is located in the freezer compartment 101; the first end of the adjusting component 300 is configured to move along a first direction, thereby driving the second end of the adjusting component 300 to move along a second direction to block at least a portion of the freezing air inlet 202; wherein the first direction and the second direction have an angle.

[0117] The second end of the regulating component 300 is located in the freezing air duct 201 , so as to shield at least a portion of the freezing air inlet 202 .

[0118] In the embodiment of the present application, the user can control the second end of the adjusting component 300 by operating the first end of the adjusting component 300 so that the second end of the adjusting component 300 blocks at least a portion of the freezing air inlet 202 .

[0119] In this way, by partially blocking the freezing air inlet 202, the air intake of the freezing compartment 101 is reduced, so that the temperature of the freezing compartment 101 is greater than 0°C.

[0120] In some embodiments, by partially blocking the freezing air inlet 202, the air intake of the freezing compartment 101 is made equal to the air intake of the refrigerating compartment 102. When the refrigerating compartment 102 reaches the refrigerating temperature, the temperature of the freezing compartment 101 is greater than 0°C, so that the freezing compartment 101 is converted into the refrigerating compartment.

[0121] Among them, the air intake volume of the freezing compartment 101 is equivalent to the air intake volume of the refrigerating compartment 102. It can be understood that the difference between the air intake volume of the freezing compartment 101 and the air intake volume of the refrigerating compartment 102 is within the set range. As long as the temperature in the refrigerating compartment 102 reaches the refrigerating temperature and the compressor 130 is shut down, the temperature of the freezing compartment 101 is greater than 0°C.

[0122] In some embodiments of the present application, the first direction and the second direction have an angle, which can be understood as the angle between the first direction and the second direction being greater than 0° and less than or equal to 90°.

[0123] In some embodiments, the first direction is the X-axis direction in the accompanying drawings, and the second direction is the Z-axis direction in the accompanying drawings. Such an arrangement can not only make the structure of the adjustment component 300 more compact, but also make the mobile operation more convenient and reduce the possibility of misoperation; it can also avoid the situation where misoperation is easy to occur under the action of gravity due to the tilted setting.

[0124] Exemplary, combined Figure 6 When the first end of the adjusting component 300 is configured to move along the positive direction of the X-axis, the second end of the adjusting component 300 is driven to move along the positive direction of the Z-axis to block at least part of the freezing air inlet 202. At this time, the first direction is the positive direction of the X-axis, and the second direction is the positive direction of the Z-axis.

[0125] In some embodiments of the present application, the adjustment component 300 is configured to adjust the size of the freezing air inlet 202 in multiple gears, which can not only achieve the conversion from freezing to refrigerated storage, but also adjust the storage temperature in the freezing state.

[0126] In other embodiments of the present application, the adjustment component 300 is configured to adjust the size of the freezing air inlet 202 in a single gear, only realizing the conversion from freezing to refrigerated storage.

[0127] In some embodiments of the present application, Figure 5 and Figure 6 The adjustment assembly 300 includes a sliding member 310, which is mounted on the freezing air duct structure 200, and a portion of the sliding member 310 extends into the freezing compartment 101, so that the user can operate the adjustment assembly 300. In the embodiment of the present application, the sliding member 310 is configured to slide along a first direction, and the sliding member 310 forms a first end of the adjustment assembly 300.

[0128] In some embodiments of the present application, the adjustment assembly 300 further includes a shielding member 320, which is installed in the freezing air duct 201; the shielding member 320 is configured to shield at least a portion of the freezing air inlet 202, thereby reducing the air intake area of ​​the freezing air inlet 202, so as to reduce the air intake volume of the freezing compartment 101. Alternatively, the shielding member 320 is also configured to be staggered with the freezing air inlet 202, so that the freezing compartment 101 maintains the original air intake volume, thereby maintaining a frozen storage environment. The shielding member 320 constitutes the second end of the adjustment assembly 300.

[0129] In some embodiments, the shielding member 320 may be a shielding plate, which can not only shield the freezing air inlet 202 , but also reduce the space occupied by the shielding member 320 in the thickness direction of the freezing air duct structure 200 , thereby reducing the shielding of the freezing air duct 201 .

[0130] In some embodiments, the freezing air inlet 202 includes a plurality of first openings, some of which are arranged at intervals in the height direction. The shielding member 320 is provided with at least one second opening, and when a plurality of second openings are provided, the plurality of second openings are arranged at intervals in the height direction. When the shielding member 320 is staggered with the freezing air inlet 202, the second opening of the shielding member 320 is opposite to the first opening, so as to avoid the shielding member 320 blocking the freezing air inlet 202; when the shielding member 320 blocks at least a portion of the freezing air inlet 202, the second opening can be opposite to at least a portion of the first opening, so as to avoid the shielding member 320 completely blocking a portion of the first opening, so that the air intake uniformity of the freezing compartment 101 is poor.

[0131] In some embodiments of the present application, the shielding member 320 serves to shield the freezing air inlet 202, so the shielding member 320 is located at the top of the freezing air duct structure 200; the sliding member 310 is arranged at the bottom of the freezing air duct structure 200 for easy user operation.

[0132] In some embodiments, the adjustment assembly 300 further includes a linkage mechanism 330 , one end of the linkage mechanism 330 is connected to the shielding member 320 , and the other end of the linkage mechanism 330 is opposite to the sliding member 310 along the first direction.

[0133] When the sliding member 310 is configured to slide along the first direction, the blocking member 320 is driven to slide along the second direction through the linkage mechanism 330 to adjust the size of the freezing air inlet 202 .

[0134] In this way, the linkage mechanism 330 is configured to transfer the sliding of the sliding member 310 along the first direction to the sliding of the shielding member 320 along the second direction. When the first direction is the horizontal X-axis direction and the second direction is the vertical Z-axis direction, the sliding member 310 slides along the X-axis direction, which saves effort and is convenient for users to operate; the shielding member 320 moves vertically to facilitate shielding the top freezing air inlet 202.

[0135] In some embodiments, the sliding member 310 and the other end of the linkage mechanism 330 are spaced apart along the first direction; when the sliding member 310 is configured to slide along the first direction until it abuts against the other end of the linkage mechanism 330 , the linkage mechanism 330 is driven to move.

[0136] For example, in Figure 6 In the illustrated perspective, the sliding member 310 is located on the left side of the linkage mechanism 330. When the sliding member 310 slides toward the linkage mechanism 330 and abuts against the linkage mechanism 330, the sliding member 310 can push the linkage mechanism 330 to move.

[0137] In the embodiment of the present application, the sliding member 310 and the linkage mechanism 330 are spaced apart from each other, so as to reduce the difficulty of assembling the adjustment component 300. Furthermore, the linkage mechanism 330 is driven to move by the abutment between the sliding member 310 and the linkage mechanism 330, so that the shielding member 320 partially shields the freezing air inlet 202. There is no need to adjust the size of the freezing air inlet 202, and only the freezing air inlet 202 needs to be shielded to achieve the conversion from freezing to refrigeration.

[0138] In some possible implementations, part of the sliding member 310 is located in the freezing air duct 201 and between the freezing fan 240 and the refrigerating connecting port 203. By adjusting the sliding member 310, the amount of cold air entering the refrigerating connecting port 203 can also be adjusted, thereby adjusting the temperature of the refrigerating compartment 102. At this time, there is a gap between the sliding member 310 and the linkage mechanism 330, so as to prevent the sliding member 310 from driving the linkage mechanism 330 and the shielding member 320 to move when adjusting the air volume of the refrigerating connecting port 203.

[0139] It should be noted here that Figure 6 By canceling the abutment of the sliding member 310 on the linkage mechanism 330 , and under the action of the linkage mechanism 330 , the linkage mechanism 330 can be restored to the initial state, thereby ensuring a frozen storage environment of the freezing chamber 101 .

[0140] In other embodiments, the sliding member 310 is connected to the other end of the linkage mechanism 330 , and the connection method between the sliding member 310 and the linkage mechanism 330 includes but is not limited to screw connection, clamping, etc.

[0141] When part of the sliding member 310 is located in the freezing air duct 201 and the sliding member 310 slides along the first direction to adjust the cold air cooling of the refrigeration connecting port 203, since the sliding member 310 drives the linkage mechanism 330 to move when sliding, the structure of the shielding member 320 and the freezing air inlet 202 should be set so that when the sliding member 310 adjusts the cold air volume of the refrigeration connecting port 203, the shielding member 320 and the freezing air inlet 202 are staggered.

[0142] In the embodiment of the present application, the sliding member 310 is connected to the linkage mechanism 330, so that the sliding member 310 drives the linkage mechanism 330 to move along the first direction, thereby driving the shielding member 320 to shield at least part of the freezing air inlet 202, thereby ensuring the stability of the sliding force transmission; and the reverse movement of the sliding member 310 can also be utilized to restore the linkage mechanism 330 to the initial position, making the structural setting of the linkage mechanism 330 more flexible.

[0143] In some embodiments of the present application, the adjustment component 300 is provided with a sliding member 310, a linkage mechanism 330 and a shielding member 320, and a portion of the sliding member 310 extends into the freezing compartment 101, so that a user can operate the sliding member 310 to slide along a first direction, and drive the shielding member 320 to move along a second direction through the linkage mechanism 330 to shield at least a portion of the freezing air inlet 202, thereby reducing the air intake area of ​​the freezing air inlet 202 and reducing the air intake amount of the freezing compartment 101, so that the air intake amount of the freezing compartment 101 is equivalent to the air intake amount of the refrigerating compartment 102, and when the refrigerating compartment 102 reaches the refrigerating temperature, the temperature of the freezing compartment 101 is greater than 0°C, so that the freezing compartment 101 is converted into a refrigerating compartment.

[0144] Combination Figure 5 and Figure 6 In some embodiments, a first slideway 206 extending along a first direction is formed in the freezing air duct structure 200 .

[0145] Exemplarily, a first slideway 206 is formed on at least one of the air duct plate 230 and the first cover plate 210 to limit the movement of the linkage mechanism 330 along the first direction. In some embodiments of the present application, the first slideway 206 is formed on the air duct plate 230 to facilitate communication with the slideway of the sliding member 310, which not only helps to simplify the structural setting, but also makes the sliding of the sliding member 310 and at least part of the linkage mechanism 330 slide more smoothly along the first direction.

[0146] In some embodiments, the linkage mechanism 330 includes a first guide rail 331 slidably installed in the first slideway 206 , and the first guide rail 331 is spaced from the sliding member 310 along the first direction, or the first guide rail 331 is connected to the sliding member 310 .

[0147] In some embodiments of the present application, the first slide 206 is located outside the freezing air duct 201 to prevent the sliding of the first guide rail 331 from interfering with the air flow in the freezing air duct 201 .

[0148] In the embodiment of the present application, the linkage mechanism 330 slides along the first direction in the first slideway 206 by setting the first guide rail 331, so that the motion transmission of the linkage mechanism 330 is more stable, the smoothness of the movement of the adjustment component 300 is improved, and the possibility of the mechanism getting stuck is reduced.

[0149] In some embodiments, a second slideway 207 extending along the second direction is formed in the freezing air duct structure 200 to limit the movement of the linkage mechanism 330 along the second direction.

[0150] Exemplarily, a second slide 207 is formed on the air duct plate 230, and the thickness of the air duct plate 230 is relatively large, so there is sufficient space for setting the slide.

[0151] In some embodiments, the linkage mechanism 330 further includes a second guide rail 332 , which is slidably installed in the second slideway 207 , and a first end of the second guide rail 332 is fixedly connected to the shielding member 320 .

[0152] In some embodiments of the present application, the second slide 207 is located on the side of the refrigeration air duct 201 , which can prevent the setting of the second slide 207 from affecting the layout of the refrigeration air duct 201 and prevent the movement of the second guide rail 332 from interfering with the gas flow in the refrigeration air duct 201 .

[0153] In the embodiment of the present application, the linkage mechanism 330 slides along the second direction in the second slideway 207 by setting the second guide rail 332, so that the movement of the shielding member 320 is more stable, thereby facilitating improving the smoothness of the movement of the shielding member 320 along the second direction.

[0154] In some embodiments, a guide slide is also formed on the refrigeration air duct structure 200, and the guide slide extends along the second direction; the shielding member 320 is located in the guide slide to limit the shielding member 320 from sliding along the second direction, thereby reducing the shielding effect of the inclination of the shielding member 320 on the refrigeration air inlet 202.

[0155] Continue to refer to Figure 5 and Figure 6 In some embodiments, a first elastic member 333 is provided at an end of the second slide 207 opposite to the second end of the second guide rail 332. In this way, the first elastic member 333 is provided at the end of the second slide 207 away from the shielding member 320. When the linkage mechanism 330 returns to the initial position, it can play an elastic buffering and limiting role for the second guide rail 332. In particular, when there is a gap between the first guide rail 331 and the sliding member 310, the linkage mechanism 330 returns to the initial position under the action of gravity. The first elastic member 333 can make the second guide rail 332 elastically contact with the second slide 207, thereby avoiding abnormal noise caused by the rigid contact between the second guide rail 332 and the second slide 207.

[0156] The first elastic member 333 may be a spring, an elastic rubber plug, etc.

[0157] The first elastic member 333 may be restricted in the second slideway 207 by a limiting member, and the first elastic member 333 may also be clamped or bonded in the second slideway 207 . The embodiment of the present application does not limit the fixing method of the first elastic member 333 .

[0158] Combination Figure 7 and Figure 8 In some embodiments, a third slide 208 extending along the first direction is formed in the freezing air duct structure 200 , and a sliding opening 209 is provided on the front side wall of the third slide 208 .

[0159] In some embodiments, the air duct plate 230 and the first cover plate 210 jointly form a third slide 208, and a sliding opening 209 is formed on the first cover plate 210. The sliding direction of the sliding member 310 is jointly limited by the air duct plate 230 and the first cover plate 210, which not only makes the formation structure of the third slide 208 simple and easy to process; but also facilitates the assembly of the refrigeration air duct structure 200 and the sliding member 310.

[0160] The sliding member 310 is slidably disposed in the third slideway 208, so that the sliding member 310 can slide along the first direction; and part of the sliding member 310 extends into the freezer compartment through the slide opening 209, which is convenient for the user to operate the sliding member 310 to move in the freezer compartment.

[0161] In some embodiments of the present application, a third slide 208 extending along the first direction is formed in the freezing air duct structure 200 to limit the movement of the sliding member 310 along the first direction; and a sliding opening 209 is provided so that a portion of the sliding member 310 extends into the freezer compartment through the sliding opening 209, making it convenient for the user to operate the sliding member 310 to move in the freezer compartment.

[0162] Continue to refer to Figure 8 In some embodiments, the sliding member 310 includes a first plate portion 311 , and the first plate portion 311 is opposite to the front side wall of the third slideway 208 , that is, the first plate portion 311 is opposite to the first cover plate 210 .

[0163] In some embodiments, the sliding member 310 further includes an operating portion 313, which is disposed on the front side of the first plate portion 311, that is, the operating portion 313 is located on the side of the first plate portion 311 facing the first cover plate 210. The operating portion 313 may be block-shaped, column-shaped, etc. The operating portion 313 extends into the freezing chamber through the sliding opening 209, so that the user can operate the sliding member 310 conveniently.

[0164] In some embodiments, the sliding member 310 further includes a side portion 312, which is disposed at the edge of the front side of the first plate portion 311, and the side portion 312 contacts the front side wall of the third slideway 208. In this configuration, compared with the first plate portion 311 contacting the front side wall of the third slideway 208, the side portion 312 is configured to contact the front side wall of the third slideway 208 to reduce the contact area between the sliding member 310 and the front side wall of the third slideway 208, thereby reducing the sliding resistance between the sliding member 310 and the front side wall of the third slideway 208, so that the sliding of the sliding member 310 is smoother.

[0165] Exemplarily, the side portion 312 is annular and is disposed on the edge of the front side of the first plate portion 311 . The operating portion 313 is located on the inner side of the side portion 312 . The side portion 312 can also serve to improve the structural strength of the sliding member 310 .

[0166] Exemplarily, the side portion 312 includes two side edges, both of which extend along the first direction, and the two side edges are spaced apart in a direction perpendicular to the first direction, which can not only reduce the contact area between the sliding member 310 and the first cover plate 210, but also guide the sliding of the sliding member 310.

[0167] In some embodiments, a groove is provided on one side of the first plate portion 311 facing the first cover plate 210 to form a side portion 312 at the edge of the first plate portion 311 , so that the structure of the sliding member 310 is simple and easy to process.

[0168] Reference Figure 8 In some embodiments, the sliding member 310 further includes a second plate portion 315 , which is disposed on the rear side of the first plate portion 311 , and the second plate portion 315 is located on a side of the first plate portion 311 away from the operating portion 313 .

[0169] Exemplarily, a set angle is formed between the second plate portion 315 and the first plate portion 311. It can be understood that the second plate portion 315 and the first plate portion 311 are not parallel. For example, the second plate portion 315 is perpendicular to the first plate portion 311. This makes it easy to use the relationship between the second plate portion 315 and the freezing air duct 201 to adjust the amount of cold air entering the refrigerated compartment.

[0170] Combination Figures 8 to 10 At least part of the second plate portion 315 is located in the freezing air duct 201, and the part of the second plate portion 315 located in the freezing air duct 201 is provided with an air outlet 3151. When the sliding member 310 moves along the first direction, the relative position relationship between the air outlet 3151 and the freezing air duct 201 is adjusted to adjust the amount of cold air entering the refrigerating compartment from the freezing air duct 201. At this time, the sliding member 310 acts as a damper.

[0171] When the sliding member 310 slides along the first direction until it contacts the linkage mechanism 330, so that the shielding member 320 moves along the second direction to shield a portion of the freezing air inlet 202, so that the freezing compartment is converted into the refrigerating compartment, the air outlet 3151 of the sliding member 310 can be completely opposite to the freezing air duct 201, so as to increase the amount of cold air entering the refrigerating compartment, so that the amount of cold air in the refrigerating compartment is equivalent to that in the freezing compartment, thereby realizing the conversion of the freezing compartment into the refrigerating compartment.

[0172] Based on the above structure of the sliding member 310, Figure 8 The sliding opening 209 is provided on the first cover plate 210. The first cover plate 210 and the air duct plate 230 define a first guide channel together, so that the first plate portion 311 and the side portion 312 of the sliding member 310 are located in the first space; a second guide channel connected to the first guide channel is formed on the air duct plate 230, so that the second plate portion 315 is located in the second guide channel. The first guide channel and the second guide channel together form a third slideway 208.

[0173] Recombination Fig. 9 and Fig.10 In some embodiments, a stop portion 314 is provided on one of the side walls of the sliding member 310 and the third slide 208, and a plurality of latching positions 211 are provided on the other of the side walls of the sliding member 310 and the third slide 208. The plurality of latching positions 211 are arranged at intervals along the first direction, and the stop portion 314 is engaged with the latching positions 211.

[0174] The following description is made by taking an example in which the stopper 314 is provided on the sliding member 310 and a plurality of latching positions 211 are provided on the side wall of the third slideway 208 .

[0175] Combination Fig. 9 and Fig.10 In some embodiments, the first cover plate 210 includes a plate body 212 , which is opposite to the air duct plate 230 along the thickness direction of the refrigerator. A fixing structure of a refrigeration fan may be provided on the plate body 212 , and a refrigeration air inlet 202 is provided on the plate body 212 .

[0176] In some embodiments, the first cover plate 210 also includes a slide side wall 213 arranged on the plate body 212, the slide side wall 213 extends along the first direction, and two slide side walls 213 are arranged, the two slide side walls 213 can be spaced apart along the second direction, and the two slide side walls 213 define a portion that forms the third slide 208, so that the first plate portion 311 and the side portion are located between the two slide side walls 213.

[0177] Both ends of the two slideway side walls 213 along the first direction may respectively serve as limiting walls to limit the extreme position of the sliding member 310 or the first guide rail 331 sliding along the first direction.

[0178] In some embodiments, the two slideway side walls 213 are respectively provided with limit buckles 214 to limit the sliding member 310 on the first cover plate 210 .

[0179] A plurality of latching positions 211 are provided on one of the slide side walls 213 , and a stopper 314 is provided on the side of the first plate portion 311 facing the slide side wall 213 . The stopper 314 and the latching positions 211 are engaged with each other to fix the sliding member 310 at a set position.

[0180] Exemplarily, the latching position 211 is an opening disposed on the side wall 213 of the slide, and the stopper 314 is a protrusion disposed on the side of the first plate portion 311. The relative fixation of the sliding member 310 and the third slide 208 is achieved through the cooperation between the protrusion and the opening.

[0181] In some embodiments, the stopper 314 is configured as an elastic stopper 314, which can cooperate with the latch 211 to relatively fix the position of the sliding member 310 and the third slideway 208, and can also be deformed to make the sliding member 310 slide along the third slideway 208. Exemplarily, the stopper 314 is a hollow convex bump disposed on the side of the first plate portion 311.

[0182] In some embodiments, the stopper 314 and the first guide rail 331 are respectively located at two ends of the sliding member 310 along the first direction.

[0183] When the sliding member 310 abuts against the first guide rail 331 and pushes the first guide rail 331 to slide along the first direction, the shielding member 320, driven by the second guide rail 332, partially shields the freezing air inlet 202, so that the air intake of the freezing compartment 101 is equivalent to the air intake of the refrigerating compartment 102. When the temperature of the refrigerating compartment 102 reaches the shutdown temperature of the compressor, the temperature of the freezing compartment 101 is higher than 0°C, so that the freezing compartment 101 is converted into a refrigerating compartment.

[0184] When the sliding member 310 is disengaged from the first guide rail 331 and there is a gap therebetween, the relative position relationship between the air outlet 3151 and the freezing air duct 201 is adjusted through the cooperation of the stopper 314 and different latching positions 211, thereby adjusting the amount of cold air entering the refrigerating compartment 102, and further adjusting the refrigerating temperature of the refrigerating compartment 102.

[0185] Furthermore, through the cooperation of the stopper 314 and the latch 211 , not only can the user's operating experience be enhanced, but the user can also determine through hearing and touch that the sliding member 310 has been adjusted to the set position, allowing the user to accurately select and locate the position of the sliding member 310 and avoid misoperation of the sliding member 310 .

[0186] Therefore, the sliding member 310 of the embodiment of the present application can not only cooperate with the linkage mechanism 330 and the shielding member 320 to achieve the temperature of the freezing chamber 101 greater than 0°C to achieve refrigeration, but also adjust the air volume entering the refrigerating chamber 102, thereby adjusting the refrigerating temperature of the refrigerating chamber 102.

[0187] According to the above description, the linkage mechanism 330 of the embodiment of the present application receives the sliding of the sliding member 310 along the first direction by setting the first guide rail 331, and drives the shielding member 320 to slide along the second direction by setting the second guide rail 332; the linkage mechanism 330 also includes an intermediate transmission member to convert the movement of the first guide rail 331 along the first direction into the movement of the second guide rail 332 along the second direction.

[0188] There are many structures of the intermediate transfer member, and nine possible structures are listed below. However, this is not a limitation on the structure of the intermediate transfer member, as long as it can convert movement in the first direction into movement in the second direction.

[0189] Example 1

[0190] Combination Figure 5 and Figure 6 In some embodiments of the present application, the linkage mechanism 330 also includes a first hinged rod 334, and both ends of the first hinged rod 334 are respectively hinged to the first guide rail 331 and the second guide rail 332, and the hinge method can be through a hinge, a hinge shaft, etc.

[0191] exist Figure 6 In the orientation shown, when the first guide rail 331 moves along the positive direction of the X-axis, the first hinged rod 334 and the hinged end of the first guide rail 331 rotate and move along the positive direction of the X-axis; the first hinged rod 334 rotates clockwise, and the hinged end of the first hinged rod 334 and the second guide rail 332 moves downward, thereby driving the second guide rail 332 to move along the negative direction of the Z-axis, so that the covering member 320 blocks part of the freezing air inlet 202.

[0192] In some embodiments of the present application, in the initial position of the linkage mechanism 330, the connecting end of the first hinge rod 334 and the second guide rail 332 is located below the first guide rail 331, so that the first hinge rod 334 is tilted downward relative to the first guide rail 331. In this way, when there is a gap between the sliding member 310 and the first guide rail 331, the linkage mechanism 330 can be restored to its initial position under the action of gravity of the second guide rail 332 and the shielding member 320 without the need for an additional recovery structure.

[0193] In the embodiment of the present application, by providing a first hinge rod 334, the two ends of the first hinge rod 334 are respectively hinged to the first guide rail 331 and the second guide rail 332, so that the movement of the first guide rail 331 along the first direction is converted into the movement of the second guide rail 332 along the second direction. In addition, the structure of the first hinge rod 334 is simple, which is convenient for the assembly of the linkage mechanism 330, and the installation occupies a small space, which is conducive to improving the compactness of the structure of the adjustment assembly 300. The linkage mechanism 330 is light in weight.

[0194] Example 2

[0195] Combination Fig.11 In some embodiments of the present application, the linkage mechanism 330 further includes a second hinged rod 340 , and one end of the second hinged rod 340 is hinged to the first guide rail 331 .

[0196] The linkage mechanism 330 further includes a first gear 350, and the first gear 350 is rotatably mounted on the freezing air duct structure. For example, the first gear 350 is rotatably mounted on the first cover plate or the second cover plate via a rotating shaft.

[0197] The other end of the second hinge rod 340 is hinged to the first gear 350 , and the hinge point between the second hinge rod 340 and the first gear 350 is offset from the center of the first gear 350 .

[0198] When the linkage mechanism 330 is in the initial position, the second hinge rod 340 is tilted downward, so that the linkage mechanism 330 can return to the initial position under the action of its own gravity.

[0199] A first rack 351 meshing with the first gear 350 is disposed on the second guide rail 332 , and the first rack 351 extends along the second direction.

[0200] When the first guide rail 331 moves along the positive direction of the X-axis, the second hinge rod 340 rotates clockwise, thereby driving the first gear 350 to rotate clockwise, and further driving the second guide rail 332 to move along the negative direction of the Z-axis.

[0201] In the embodiment of the present application, the movement of the first guide rail 331 along the first direction is converted into the rotation of the first gear 350 through the second hinge rod 340, and the rotation of the first gear 350 is converted into the movement of the second guide rail 332 along the second direction through the meshing of the first gear 350 and the first rack 351. Based on Example 1, the embodiment of the present application adds the first gear 350 and the first rack 351, which is conducive to improving the vertical movement accuracy of the second guide rail 332 and the force transmission efficiency.

[0202] Example 3

[0203] In some embodiments of the present application, Fig.12The linkage mechanism 330 also includes a first sector gear 360, which includes a first gear body 361 and a first handle 362 connected to each other, and the first handle 362 is arranged on the edge of the first gear body 361; the first gear body 361 is rotatably installed on the refrigeration air duct structure, for example, the first gear body 361 is rotatably installed on the first cover plate 210 or the second cover plate 220 through a rotating shaft.

[0204] In some embodiments, the first handle 362 is provided with a first oblong hole 363, and an angle is formed between the extension direction of the first oblong hole 363 and the first direction. The extension direction of the first handle 362 is the same as the extension direction of the first oblong hole 363, which is conducive to improving the compactness of the structure of the first sector gear 360.

[0205] Illustratively, in the embodiment of the present application, the angle between the extension direction of the first oblong hole 363 and the first direction is an acute angle.

[0206] The linkage mechanism 330 further includes a second sector gear 370, which includes a second gear body 371 and a second handle 372 connected to each other. The second gear body 371 is rotatably mounted on the refrigeration air duct structure, and the second handle 372 is provided with a second oblong hole 373, and an angle is formed between the extension direction of the second oblong hole 373 and the second direction. The structure of the second sector gear 370 can be the same as that of the first sector gear 360, and will not be repeated here. The angle between the extension direction of the second oblong hole 373 and the second direction can be an acute angle.

[0207] The second gear body 371 meshes with the first gear body 361 ; the first guide rail 331 is provided with a first matching column 381 that matches with the first oblong hole 363 ; the second guide rail 332 is provided with a second matching column 382 that matches with the second oblong hole 373 .

[0208] When the first guide rail 331 moves along the positive direction of the X-axis, the first matching column 381 moves along the positive direction of the X-axis, thereby driving the first oblong hole 363 to rotate, so that the matching position of the first matching column 381 and the first oblong hole 363 moves downward, thereby driving the first gear body 361 to rotate counterclockwise; when the first gear body 361 rotates counterclockwise, the second gear body 371 rotates clockwise, the second oblong hole 373 rotates clockwise, and the matching position of the second matching column 382 and the second oblong hole 373 moves downward, thereby driving the second guide rail 332 to move along the negative direction of the Z-axis.

[0209] In the embodiment of the present application, the linkage mechanism 330 uses two sector gears and two oblong holes, and matching columns are arranged on the two guide rails to match the oblong holes to achieve the conversion from the first direction movement to the second direction movement. The matching method of the gears makes the structure stable.

[0210] Example 4

[0211] In some embodiments of the present application, Fig.13 The linkage mechanism 330 further includes a first connecting member 390, on which a first sliding hole 391 is disposed. The extension direction of the first sliding hole 391 forms an angle with the first direction and the second direction, respectively, so that the extension direction of the first sliding hole 391 is neither parallel to the first direction nor parallel to the second direction. Exemplarily, the first guide rail 331 and the second guide rail 332 are perpendicular and intersecting, and the first connecting member 390 is obliquely disposed between the first guide rail 331 and the second guide rail 332.

[0212] The first connecting member 390 is fixedly connected to the second guide rail 332 . A third matching column 392 is provided on the first guide rail 331 . The third matching column 392 matches with the first sliding hole 391 .

[0213] When the first guide rail 331 moves along the positive direction of the X-axis, the third matching column 392 moves along the positive direction of the X-axis, driving the first connecting member 390 to move along the negative direction of the Z-axis, thereby driving the second guide rail 332 to move along the negative direction of the Z-axis.

[0214] In the embodiment of the present application, a first connecting member 390 is provided to be fixedly connected with the second guide rail 332, a first sliding hole 391 is provided on the first connecting member 390, a third matching column 392 is provided on the first guide rail 331 to match with the first sliding hole 391, and the first sliding hole 391 is tilted to realize the conversion from the first direction to the second direction, and the structure is simple.

[0215] Example 5

[0216] In some embodiments of the present application, Fig.14 The linkage mechanism 330 further includes an inclined guide rail 400 and a second connecting member 410. The second connecting member 410 is configured to form an inclined slide 411. The extending direction of the inclined slide 411 forms an angle with the first direction and the second direction respectively. The extending direction of the inclined slide 411 intersects the first direction, and the extending direction of the inclined slide 411 intersects the second direction. Exemplarily, the extending direction of the inclined slide 411 forms an acute angle with the X-axis direction, and the extending direction of the inclined slide 411 forms an acute angle with the Z-axis direction.

[0217] The second connecting member 410 is fixedly connected to the second guide rail 332 , the inclined guide rail 400 is fixedly connected to the first guide rail 331 , and at least a portion of the inclined guide rail 400 is located in the inclined slideway 411 .

[0218] In some embodiments, first guide rails 331 are respectively connected to both ends of the inclined guide rail 400 to improve the structural stability of the linkage mechanism 330 .

[0219] When the first guide rail 331 moves along the positive direction of the X-axis, the inclined guide rail 400 is driven to move along the positive direction of the X-axis, and the matching position of the inclined guide rail 400 and the inclined slide 411 moves along the negative direction of the Z-axis, thereby driving the second guide rail 332 to move along the negative direction of the Z-axis.

[0220] In the embodiment of the present application, the second connecting member 410 is connected to the second guide rail 332 to form an inclined slide 411. By setting an inclined guide rail 400 connected to the first guide rail 331, and utilizing the cooperation between the inclined guide rail 400 and the inclined slide 411, the movement of the first guide rail 331 along the first direction is converted into the movement of the second guide rail 332 along the second direction. Not only is the structure simple, but the conversion process is also stable.

Exemplarily, the first rod portion 421 and the second rod portion 422 are perpendicular. Of course, the angle between the first rod portion 421 and the second rod portion 422 can also be an acute angle.

[0224] The connection between the first rod 421 and the second rod 422 is hinged to the refrigeration air duct structure. Exemplarily, a hinge seat 427 is provided on the refrigeration air duct structure, for example, the first cover plate or the second cover plate is provided with a hinge seat 427, and the connection between the first rod 421 and the second rod 422 is hinged to the hinge seat 427, so that the first rod 421 and the second rod 422 can rotate relative to the hinge seat 427.

[0225] The first rod portion 421 is provided with a first long slot 423 , the extension direction of which forms an angle with the first direction, and the extension direction of which is non-parallel to the first direction, for example, the extension direction of which is perpendicular to the first direction.

[0229] When the first guide rail 331 moves along the positive direction of the X-axis, the first matching member 425 moves along the positive direction of the X-axis, so that the third connecting member 420 rotates clockwise around the hinge seat 427, and the second matching member 426 drives the second guide rail 332 to move along the negative direction of the Z-axis.

[0230] In the embodiment of the present application, a third connecting member 420 having two crossed rod portions is provided, and long grooves are provided on the two crossed rod portions, which cooperate with the mating members fixed on the guide rail. By utilizing the rotation of the third connecting member 420 and the cooperation of the two long groove box mating members, the movement of the first guide rail 331 along the first direction is converted into the movement of the second guide rail 332 along the second direction. The structure is simple and there is no need to set up a complicated gear structure.

[0231] Example 7

[0232] In some embodiments of the present application, Fig.16 The linkage mechanism 330 further includes a wedge block 430, one end of which is fixedly connected to the first guide rail 331. A guide rail of the wedge block 430 is formed in the freezing air duct structure 200 to limit the movement of the wedge block 430 along the first direction.

[0234] When the first guide rail 331 moves along the positive direction of the X-axis, the wedge block 430 moves along the positive direction of the X-axis, and the contact position between the roller 440 and the wedge block 430 moves along the negative direction of the Z-axis, thereby driving the second guide rail 332 to move along the negative direction of the Z-axis.

[0235] In some embodiments, a first limiter 451 is disposed on the second slide 207 , a second limiter 452 is disposed on the second guide rail 332 , and the second limiter 452 and the first limiter 451 are spaced apart along the second direction, and the second limiter 452 is located below the first limiter 451 .

[0236] The linkage mechanism 330 also includes a second elastic member 450, which is sleeved on the outer side of the second guide rail 332, and the two ends of the second elastic member 450 are respectively abutted against the first limit member 451 and the second limit member 452, so that the roller 440 abuts against the inclined surface of the wedge block 430, thereby reducing the possibility of the roller 440 and the second guide rail 332 sliding along the inclined surface of the wedge block 430 under the action of gravity.

[0237] The linkage mechanism 330 of the embodiment of the present application converts the movement of the first guide rail 331 along the first direction into the movement of the second guide rail 332 along the second direction by providing a wedge block 430 with an inclined surface; and by providing a roller 440 on the second guide rail 332 to contact the inclined surface of the wedge block 430, the sliding conversion between the second guide rail 332 and the wedge block 430 is smoother.
