For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations

[0062] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model

[0063] Refer to Figure 1 and Figure 2 As shown, an embodiment of the present utility model provides a refrigerator, including a box body 1 and a door body 2. The box body 1 is provided with a pick-up and placement opening 111; the door body 2 is connected to the box body 1 and can move relative to the box body 1 to open and close the pick-up and placement opening 111

[0064] The cabinet 1 is generally in a cuboid frame structure. The cabinet 1 includes a cabinet shell 12 and a cabinet liner 11. The cabinet liner 11 is arranged inside the cabinet shell 12. A foaming space is formed between the cabinet liner 11 and the cabinet shell 12. The foaming space is used to install other component structures of the refrigerator and form a foaming insulation layer. The cabinet shell 12 provides protection and support for the cabinet liner 11. A refrigerating compartment is formed inside the cabinet liner 11 for storing food. A pick-and-place opening 111 is arranged on one side of the refrigerating compartment to facilitate picking and placing items into and out of the refrigerating compartment. The door body 2 is pivotally connected to the cabinet shell 12 of the cabinet 1. For example, the door body 2 can be rotatably connected or slidably connected to the cabinet shell 12.

[0065] In some embodiments, the refrigerator further includes a refrigeration system (not shown in the figure) and an air supply system (not shown in the figure). The refrigeration system and the air supply system are electrically connected to a power supply component. The power supply component is used to supply power to each component of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0066] The refrigeration system is installed inside the cabinet shell 12 and is used to supply cold air to the refrigerating compartment inside the cabinet liner 11. The refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe, and a throttling device, as well as a refrigerant. Each component is distributed at different positions inside the cabinet shell 12 according to its structural characteristics to meet the requirements of its corresponding functions. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process, and an evaporation process. The compression process is as follows: After plugging in the power cord of the refrigerator, when the contacts of the thermostat are closed, the compressor starts to work. The low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor, and then is discharged into the condenser. The condensation process is as follows: The high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and it is gradually cooled to a normal-temperature and high-pressure refrigerant saturated vapor and then cooled to a refrigerant saturated liquid. The throttling process is as follows: The condensed refrigerant saturated liquid flows into the throttling device after being filtered of moisture and impurities by the drying filter, and is throttled and depressurized through the throttling device, and the refrigerant becomes a normal-temperature and low-pressure wet vapor. The evaporation process: The normal-temperature and low-pressure wet vapor enters the evaporator, starts to absorb heat and vaporize, reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and makes the refrigerant become a low-temperature and low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor again, repeating the above process. Through the state change of the refrigerant, energy conversion is carried out, and the heat inside the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator.

[0067] The air supply system is installed inside the cabinet 12 and is used to provide power for the flow of cold air. The air supply system generally includes a fan and an air supply duct formed and defined inside the cabinet 12. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged far from the fan. In other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged far from the fan. A duct cavity is also formed and defined inside the cabinet 12. The duct cavity is respectively communicated with the air supply duct and the refrigeration compartment inside the cabinet liner 11, so that the air supply duct is communicated with the refrigeration compartment through the duct cavity. It should be noted that the cabinet liner 11 is provided with an air outlet, and the air outlet is used to connect the duct cavity and the refrigeration compartment. The cold air generated by the refrigeration system enters the duct cavity through the air supply duct by the operation of the fan and flows to the refrigeration compartment through the air outlet to refrigerate the refrigeration compartment. It should also be noted that in some embodiments, the air outlet is arranged on the side wall of the cabinet liner 11 opposite to the access opening 111 of the refrigeration compartment or on the side wall of the cabinet liner 11 adjacent to the access opening 111 of the refrigeration compartment. It should also be noted that the refrigeration system and the air supply system belong to the well-known common sense technologies in the art and will not be elaborated here.

[0068] In order to make full use of the internal space of the refrigerator and place more items, refer to Figure 3 As shown, in some embodiments, the refrigerator further includes a door shelf 3, and the door shelf 3 is installed on one side of the door body 2 facing the access opening 111. The door shelf 3 is generally a box structure with an opening on one side, and items can be placed inside the door shelf 3.

[0069] In order to adjust the height of the items placed in the door shelf 3, the height position of the door shelf 3 on the door body 2 is adjustable. Refer to Figure 3 - Figure 6 As shown, in some embodiments, the surface of the door body 2 facing the access opening 111 is provided with a plurality of connection positions 41. The connection positions 41 are arranged on the surface of the door body 2 facing the access opening 111, and the plurality of connection positions 41 are arranged along the first direction Z, and the first direction Z is the height direction of the door body 2. An adjustment mechanism 5 is installed on the door shelf 3, and through the connection and cooperation between the adjustment mechanism 5 and the connection positions 41, the connection and fixation between the door shelf 3 and the door body 2 are realized. By adjusting the height position of the connection position 41 connected by the adjustment mechanism 5, the adjustment of the height position of the door shelf 3 on the door body 2 can be realized.

[0070] Refer to Figure 7 - Figure 10As shown, in some embodiments, the adjusting mechanism 5 includes a trigger member 51, a transmission assembly 52, and a first connecting portion 53. The trigger member 51 is installed on the door shelf 3, the first connecting portion 53 is installed on the door shelf 3, and the first connecting portion 53 is matched with the connecting position 41. The transmission assembly 52 is installed on the door shelf 3, and the transmission assembly 52 connects the trigger member 51 and the first connecting portion 53. The first connecting portion 53, the transmission assembly 52, and the trigger member 51 are arranged along the second direction Y from near the door body 2 to away from the door body 2, and the second direction Y is perpendicular to the first direction Z. The trigger member 51 drives the first connecting portion 53 to move close to the connecting position 41 through the transmission assembly 52, so that the first connecting portion 53 is connected to the connecting position 41, or drives the first connecting portion 53 to move away from the connecting position, so that the first connecting portion 53 is disengaged from the connecting position 41.

[0071] When the first connecting portion 53 is connected to the connecting position 41, the connection between the door shelf 3 and the door body 2 is realized, and the position of the door shelf 3 on the door body 2 is fixed. When the first connecting portion 53 is disengaged from the connecting position 41, the door shelf 3 is disconnected from the door body 2, and the door shelf 3 is movable relative to the door body 2. At this time, by manually applying an external force to move the door shelf 3, the first connecting portion 53 on the door shelf 3 can be aligned with different connecting positions 41, and then the trigger member 51 is operated again to drive the first connecting portion 53 to move close to the connecting position 41 and connect to the aligned connecting position 41 to connect the door shelf 3 and the door body 2. Since the height positions of the connecting positions 41 connected by the first connecting portion 53 are different before and after moving the door shelf 3, the height positions of the door shelf 3 relative to the door body 2 are different before and after moving, so as to realize the adjustment of the height position of the door shelf 3, which is convenient for placing items of different heights on the door shelf 3.

[0072] In this application, the adjusting mechanism 5 is integrally arranged on the door shelf 3, which is convenient for the user to operate the adjusting mechanism 5 while holding the door shelf 3 by hand, and the operation is convenient. Moreover, after operating the trigger member 51 to disconnect the first connecting portion 53 from the connecting position 41, the door shelf 3 can move flexibly, and can rise or fall, making the adjustment of the height position of the door shelf 3 more flexible.

[0073] Refer to Figure 6 As shown, in some embodiments, an installation box 21 is provided inside the door body 2. The installation box 21 is provided with a second connecting portion 4. A plurality of slot hole structures 42 are arranged on the second connecting portion 4 along the first direction Z, and the connecting position 41 is a slot hole structure 42. The connection between the first connecting portion 53 and the second connecting portion 4 is realized by inserting the first connecting portion 53 into the slot hole structure 42. By driving the first connecting portion 53 to perform telescopic movement along the second direction Y, the insertion and disengagement of the first connecting portion 53 and the slot hole structure 42 can be realized, and the structure is simple and the operation is convenient. The first connecting portion 53 is in a cuboid shape, and the end structure of the first connecting portion 53 close to the door body 2 is matched with the shape of the slot hole structure 42. The second connecting portion 4 and the installation box 21 can be fixed by screws.

[0074] Refer to Figure 8 and Figure 10 As shown, in some embodiments, the trigger 51 includes a pressing block 511 and an elastic member 512. The pressing block 511 is connected to the transmission assembly 52. The pressing block 511 is installed on the door shelf 3. The elastic member 512 connects the pressing block 511 and the door shelf 3. For the convenience of operation, at least a part of the pressing block 511 extends out of the door shelf 3. Press the pressing block 511 towards the door shelf 3. The pressing block 511 drives the first connecting portion 53 to move away from the connection position 41 through the transmission assembly 52, so that the first connecting portion 53 is disengaged from the connection position 41. Release the pressing block 511, and the pressing block 511 moves in the reverse direction under the elastic force of the elastic member 512, and at the same time drives the first connecting portion 53 to move in the reverse direction. Before releasing the pressing block 511, align the first connecting portion 53 with the connection position 41. Then, after releasing the pressing block 511, the first connecting portion 53 moves close to the connection position 41 and can be connected to the connection position 41. The trigger 51 adopts the structural form of the pressing block 511 and the elastic member 512, so that the pressing block 511 can be automatically reset. The elastic member 512 is a spring. The trigger 51 further includes a guide post 513. The guide post 513 is fixedly connected to the door shelf 3. The elastic member 512 is sleeved on the guide post 513 in a guiding manner. The telescopic movement of the elastic member 512 is guided by the guide post 513, so as to guide the movement of the pressing block 511 and prevent the pressing block 511 from deflecting during the pressing operation.

[0075] Refer to Figure 7 、 Figure 8 and Figure 10As shown, in some embodiments, the telescopic direction of the elastic member 512 is parallel to the first direction Z, so that the pressing block 511 can move up and down relative to the door shelf 3 along the first direction Z. When pressing the pressing block 511 along the first direction Z, the pressing block 511 drives the first connecting portion 53 to move along the second direction Y through the transmission assembly 52. Specifically, when the pressing block 511 moves downward along the first direction Z, it drives the first connecting portion 53 to move away from the connecting position 41; when the pressing block 511 moves upward, it drives the first connecting portion 53 to move closer to the connecting position 41. The pressing block 511 moves up and down relative to the door shelf 3, and the user can press the pressing block 511 from top to bottom, and can also press the pressing block 511 while holding the door shelf 3 with the hand, which is convenient and fast to operate. When pressing the pressing block 511 downward, the pressing block 511 compresses the elastic member 512. After releasing the pressing block 511, the elastic member 512 provides an upward elastic force to the pressing block 511, driving the pressing block 511 to move upward. Moreover, after the pressing block 511 moves upward and resets, the elastic member 512 remains in the state of pressing the pressing block 511 upward, so that the pressing block 511 cannot move downward without other external forces, thereby keeping the first connecting portion 53 in the state of extending out of the door shelf 3, locking the connection between the first connecting portion 53 and the connecting position 41, and making the door shelf 3 firmly fixed on the door body 2.

[0076] In some embodiments, there are two side plates arranged in sequence along the third direction on the door shelf 3. The two side plates are arranged oppositely, and each side plate is provided with a first sliding groove 5411 and a second sliding groove 5412. The first sliding grooves 5411 on the two side plates are arranged oppositely, and the second sliding grooves on the two side plates are arranged oppositely. The third direction X is perpendicular to the first direction Z and the second direction Y in pairs. The groove length direction of the first sliding groove 5411 extends along the second direction Y. In the second direction Y, the second sliding groove 5412 is located between the first sliding groove 5411 and the transmission assembly 52; the groove length direction of the second sliding groove 5412 is inclined, and the height position of the end of the second sliding groove 5412 close to the first sliding groove 5411 in the first direction Z is higher than the height position of the end of the second sliding groove 5412 far from the first sliding groove 5411 in the first direction Z.

[0077] The transmission assembly 52 includes a transmission portion 521, a first transmission rod 522 and a second transmission rod 523. The two ends of the first transmission rod 522 are respectively installed in the two first sliding grooves 5411, and the end of the first connecting portion 53 far from the door body 2 is rotatably sleeved on the first transmission rod 522; the two ends of the second transmission rod 523 are respectively installed in the two second sliding grooves 5412; one end of the transmission portion 521 is fixedly connected to the first transmission rod 522 and the second transmission rod 523, and the other end is connected to the pressing block 511. The first transmission rod 522 and the second transmission rod 523 are arranged in parallel.

[0078] When pressing the pressing block 511 along the first direction Z, the pressing block 511 drives the transmission part 521 to move closer to the pressing block 511, causing the end of the transmission part 521 to roll relative to the pressing block 511 in the direction approaching the pressing block 511. The second transmission rod 523 rolls along the second chute 5412 in the direction approaching the pressing block 511. Since the second chute 5412 is inclined, the chute wall of the second chute 5412 provides an inclined reaction force to the transmission part 521, causing the transmission part 521 to have both a downward displacement and a displacement approaching the pressing block 511. During the movement of the transmission part 521, the transmission part 521 drives the first transmission rod 522 to roll along the first chute 5411 in the direction approaching the pressing block 511. Since the groove length direction of the first chute 5411 extends along the second direction Y and the first connecting part 53 is connected to the first transmission rod 522, when the first transmission rod 522 rolls along the first chute 5411, the first transmission rod 522 drives the first connecting part 53 to move in the direction approaching the transmission part 521, enabling the first connecting part 53 to move away from the connection position 41, thereby causing the first connecting part 53 to disengage from the connection position 41. Release the pressing block 511, and the pressing block 511 moves upward and resets under the action of the elastic member 512. The pressing block 511 drives the end of the transmission part 521 to roll in the opposite direction relative to the pressing block 511. The second transmission rod 523 rolls in the opposite direction in the second chute 5412, and the first transmission rod 522 rolls in the opposite direction in the first chute 5411. The first transmission rod 522 pushes the first connecting part 53 to move closer to the connection position 41 in the direction away from the pressing block 511. Through the cooperation of the first chute 5411, the second chute 5412, the first transmission rod 522, the second transmission rod 523, and the transmission part 521, a track-changing movement can be achieved, converting the vertical movement of the pressing block 511 along the first direction Z into the horizontal movement of the first connecting part 53 along the second direction Y.

[0079] To facilitate the rolling of the transmission part 521 in the first chute 5411 and the second chute 5412, the inclination angle of the second chute 5412 is set to be greater than or equal to 45° and less than 90°. If the inclination angle is too large, it will be difficult to ensure that the transmission part 521 pulls the first connecting part 53 to move away from the connection position 41. When the force applied to the trigger part 51 is of a certain magnitude, if the inclination angle is too small, the reverse horizontal component force provided by the second chute 5412 will be small, the horizontal pulling force transmitted to the first connecting part 53 will decrease, resulting in the first connecting part 53 being not easily movable; moreover, if the inclination angle is too small, it will also increase the telescopic stroke of the first connecting part 53, increasing its occupied space in the door shelf 3 and being inconvenient for layout.

[0080] Refer to Figure 8As shown, in some embodiments, the pressing block 511 is provided with two third sliding grooves 5111 arranged oppositely along the third direction X, and the groove length direction of the third sliding groove 5111 extends along the second direction Y; one end of the transmission part 521 connected to the pressing block 511 is provided with a third transmission rod 5211, and both ends of the third transmission rod 5211 are respectively installed in the third sliding groove 5111. When the transmission part 521 moves close to the pressing block 511, the third transmission rod 5211 rolls along the third sliding groove 5111. When the second transmission rod 523 rolls in the second sliding groove 5412, the transmission part 521 has a certain swinging amplitude, and through the cooperation of the third transmission rod 5211 and the third sliding groove 5111, the pressing block 511 does not interfere with the swinging of the transmission part 521.

[0081] In some embodiments, the door shelf 3 is further provided with a fixing rod 5413, the fixing rod 5413 is arranged parallel to the first transmission rod 522, a fourth sliding groove 531 is formed on one side of the first connecting part 53 close to the door body 2, and the fixing rod 5413 is inserted into the fourth sliding groove 531. When the first connecting part 53 moves under the pushing and pulling action of the first transmission rod 522, the fixing rod 5413 and the fourth sliding groove 531 move relative to each other, and through the cooperation of the fixing rod 5413 and the fourth sliding groove 531, the movement of the first connecting part 53 is guided and the end of the first connecting part 53 is prevented from sinking. In other embodiments, the guiding of the movement of the first connecting part 53 can also be realized by providing a guiding groove in the door shelf 3 and arranging a fixing rod 5413 on the first connecting part 53, and through the guiding cooperation between the end of the fixing rod 5413 and the guiding groove.

[0082] Refer to Figure 8 - Figure 11As shown, in some embodiments, the door shelf 3 is provided with a receiving cavity 31 with an open end; the adjusting mechanism 5 further includes a fixed seat 54 which is installed in the receiving cavity 31, and the trigger member 51, the transmission assembly 52 and the first connecting portion 53 are all installed on the fixed seat 54. The door shelf 3 is provided with a first through hole 311 and a second through hole 312 that communicate with the receiving cavity 31. At least a part of the trigger member 51 extends out of the first through hole 311 to facilitate pressing the trigger member 51; the second through hole 312 is arranged towards the connecting position 41, and at least a part of the first connecting portion 53 extends out of the second through hole 312 to facilitate the connection between the first connecting portion 53 and the second connecting portion 4. Integrating the trigger member 51, the transmission assembly 52 and the first connecting portion 53 on the fixed seat 54 and connecting the fixed seat 54 to the door shelf 3. During assembly, the trigger member 51, the transmission assembly 52 and the first connecting portion 53 can be pre-assembled with the fixed seat 54 into a whole outside, and then this whole is placed into the receiving cavity 31. Through the connection between the fixed seat 54 and the door shelf 3, the installation and fixation of the whole adjusting mechanism 5 in the door shelf 3 are realized, and this method facilitates the installation of the adjusting mechanism 5. In some embodiments, the fixed seat 54 is detachably installed in the receiving cavity 31. A card hole 313 communicating with the receiving cavity 31 can be opened on the door shelf 3, and a snap 5421 is opened on the fixed seat 54. When the fixed seat 54 is placed in the receiving cavity 31, the snap 5421 is stuck in the card hole 313 to realize the detachable connection between the fixed seat 54 and the door shelf 3. The opening of the receiving cavity 31 can be arranged downward to enhance the aesthetic appearance of the door shelf 3.

[0083] Referring to Figure 8 As shown, the fixed seat 54 can adopt a split structure. The fixed seat 54 includes a first seat body 541 and a second seat body 542. The first seat body 541 and the second seat body 542 are connected and fixed up and down. The trigger member 51, the transmission assembly 52 and the first connecting portion 53 are all installed on the first seat body 541, and the snap 5421 is fixed on the second seat body 542, and the detachable connection with the door shelf 3 is realized through the second seat body 542. To facilitate the installation of the transmission assembly 52, the first seat body 541 is in a U-shaped groove structure, and the side plates serve as the groove walls of the U-shaped groove. The first chute 5411 and the second chute 5412 are both opened on the groove walls of the U-shaped groove. The transmission portion 521 and the first connecting portion 53 are both placed in the inner space of the U-shaped groove. The two ends of the fixed rod 5413 are respectively fixed on the opposite two groove walls of the U-shaped groove. The guide post 513 is fixed on the first seat body 541, and the elastic member 512 is sleeved on the guide post 513. In other embodiments, if the fixed seat 54 is fixedly connected or integrally formed with the door shelf 3, then the first chute 5411 and the second chute 5412 are both opened on the door shelf.

[0084] In some embodiments, first guiding portions 22 are provided on both sides of the door body 2 in the third direction, and the first guiding portions 22 extend along the first direction Z; second guiding portions 32 are provided on both sides of the door shelf 3. The first guiding portion 22 is one of a guiding groove structure and a guiding block structure, and the second guiding portion 32 is the other of the guiding groove structure and the guiding block structure. The guiding block structure is installed in the guiding groove structure. When the height position of the door shelf 3 is adjusted by pressing the pressing block 511, the cooperation between the first guiding portion 22 and the second guiding portion 32 can guide the lifting movement of the door shelf 3. Moreover, after releasing the pressing block 511 to connect the door shelf 3 with the door body 2, the cooperation between the first guiding portion 22 and the second guiding portion 32 can also prevent the door shelf 3 from swinging towards the direction close to the door body 2, enhancing the stability of the door shelf 3 on the door body 2. In this embodiment, the first guiding portion 22 is a guiding groove structure, and the second guiding portion 32 is a guiding block structure embedded in the guiding groove structure. In order to increase the layout space of the door shelf 3, an avoidance groove 33 is provided on the side of the door shelf 3, and the guiding block structure constitutes one groove wall of the avoidance groove 33. When the first guiding portion 22 cooperates with the second guiding portion 32, one groove wall of the guiding groove structure is embedded in the avoidance groove 33.

[0085] In order to improve the connection stability of the door shelf 3 on the door body 2 and make the forces on both sides of the door shelf 3 balanced, second connecting portions 4 are provided on both sides of the door body 2 in the third direction X, and adjusting mechanisms 5 corresponding to the second connecting portions 4 are installed on both sides of the door shelf 3. Moreover, when holding up the door shelf 3 with both hands, both hands can simultaneously press the triggering members 51 of the adjusting mechanisms 5, and the operation is stable.

[0086] The working process of the present utility model is as follows:

[0087] When it is necessary to adjust the height position of the door shelf 3 on the door body 2, hold up the door shelf 3 with both hands and press the pressing blocks 511 on both sides of the door shelf 3 at the same time. During the downward movement of the pressing blocks 511, the end of the transmission part 521 rolls in the third chute 5111, and the second transmission rod 523 rolls in the second chute 5412. The transmission part 521 swings downward, pulling the first transmission rod 522 to roll in the first chute 5411 in the direction close to the pressing block 511. By pulling the first transmission rod 522, the first connecting part 53 is pulled away from the connection position 41, so that the first connecting part 53 is disengaged from the connection position 41. At this time, the door shelf 3 can move along the first direction Z under the lifting action of manual external force. According to the required height position of the door shelf 3, align the first connecting part 53 with the connection position 41 at the corresponding height position, release the pressing block 511, and the pressing block 511 moves in the reverse direction under the elastic force of the elastic part 512, so that the transmission part 521 and the first connecting part 53 move in the reverse direction. The first connecting part 53 moves close to the connection position 41 and is inserted into the aligned connection position 41, realizing the connection between the first connecting part 53 and the connection position 41 again, so as to realize the fixation of the door shelf 3 and the door body 2 after adjusting the height position.

[0088] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
