DETAILED DESCRIPTION

[0042] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

The wording "and / or" used here includes all or any unit and all combinations of one or more associated listed items.

[0044] As a common appliance in daily life, refrigerators are now widely used. Users can store food in refrigerators to prevent food from spoiling.

[0045] In this embodiment, the refrigerator includes a box body 1 and a shelf 3.

[0046] The box body 1 is used to form the overall appearance of the refrigerator. The box body 1 is roughly in the shape of a rectangular frame. The top of the box body 1 and the bottom of the box body 1 are opposite ends. From the top of the box body 1 to the bottom of the box body 1 is the height direction of the box body 1, the left side of the box body 1 and the right side of the box body 1 are opposite sides, from the left side of the box body 1 to the right side of the box body 1 is the width direction of the box body 1, the front side of the box body 1 and the back side of the box body 1 are opposite sides, and from the front side of the box body 1 to the back side of the box body 1 is the thickness direction of the box body 1.

[0047] The box body 1 is provided with a refrigerating chamber 11 inside, and the refrigerating chamber 11 is used to place goods. The refrigerating chamber 11 is provided with a chamber opening, and the chamber opening direction is arranged toward the front side of the box body 1. The refrigerating chamber 11 can be in a refrigerating temperature environment, a freezing temperature environment, or a normal temperature environment. A door body 2 is provided at the chamber opening, and the door body 2 is arranged in a straight plate shape at the front side of the box body 1. The door body 2 can be connected to the box body 1 in an openable and closable manner to open or close the refrigerating chamber 11.

[0048] It can be understood that the refrigerator also includes a refrigeration system and an air supply system. The refrigeration system is installed in the box 1, and the refrigeration system is used to provide cold air to the refrigeration room 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 and a refrigerant. Each component is distributed at different positions of the box 1 according to its structural characteristics to meet the requirements of its corresponding function. 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: after the power cord of the refrigerator is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and 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 discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and is cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device. The throttling device is used to throttle and reduce the pressure, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the state change of the refrigerant, and the heat in the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator.

[0049] The air supply system is installed in the box 1 to provide power for the flow of cold air. The air supply system generally includes a fan and a guide cavity. In some embodiments, the air inlet end of the guide cavity is arranged close to the fan, and the air outlet end of the guide cavity is arranged away from the fan. In other embodiments, the air outlet end of the guide cavity is arranged close to the fan, and the air inlet end of the guide cavity is arranged away from the fan. The fan drives the air in the guide cavity, and the evaporator is correspondingly arranged in the guide cavity. The cold air cooled by the evaporator flows along the guide cavity through the driving part of the fan and finally enters the cold storage room 11 to perform a cooling operation on the cold storage room 11.

[0050] Based on this, Figures 1 to 13As shown, the utility model relates to a refrigerator, comprising:

[0051] A box body 1, wherein the box body 1 has a refrigerating chamber 11, wherein two opposite sides of the refrigerating chamber 11 are provided with ribs 12, and the ribs 12 are extended in the front-back direction;

[0052] A door body 2, the door body 2 is hinged to the box body 1, and is used to open or close the refrigerating chamber 11;

[0053] The shelf 3 includes a fixed layer plate 31, a folding layer plate 32 and a locking mechanism 33. The fixed layer plate 31 and the folding layer plate 32 are both connected between the ribs 12 on both sides of the refrigerating chamber 11, and the folding layer plate 32 is located below the fixed layer plate 31. The folding layer plate 32 can move in the front-back direction. The locking mechanism 33 includes a telescopic rod 331 and a driving component both provided in the folding layer plate 32. The driving component is used to drive the end of the telescopic rod 331 to extend out of the side wall of the folding layer plate 32 or retract into the folding layer plate 32;

[0054] A guide rail 4, the guide rail 4 is arranged at the rib 12 and extends in the front-to-back direction, and the guide rail 4 is provided with a plurality of latch teeth 41 for the telescopic rod 331 to enter at intervals along the length direction;

[0055] After the driving assembly drives the telescopic rod 331 to extend from the side wall of the folding layer 32 and be clamped between the clamping teeth 41 of the guide rail 4, the folding layer 32 can be restricted from moving in the front-rear direction.

[0056] In the present invention, ribs 12 are provided on opposite sides of the refrigerating chamber 11, the fixed layer plate 31 and the folding layer plate 32 are both connected between the ribs 12 on both sides of the refrigerating chamber 11, the fixed layer plate 31 is fixed between the ribs 12 on both sides of the refrigerating chamber 11, the folding layer plate 32 can be moved in the front-to-back direction to adjust the position of the folding layer plate 32, and the folding layer plate 32 is located below the fixed layer plate 31, so that the folding layer plate 32 can be moved and stored directly below the fixed layer plate 31, and at the same time, a guide rail 4 is provided at the ribs 12, and the guide rail 4 is provided with a plurality of latch teeth 41 at intervals along the length direction, the driving component can drive the telescopic rod 331 to extend from the side wall of the folding layer plate 32 and be clamped between the latch teeth 41 of the guide rail 4, so that the folding layer plate 32 can be restricted from continuing to move in the front-to-back direction, and the position of the folding layer plate 32 can be infinitely adjusted, so that the user can adjust the position of the folding layer plate 32 according to the required avoidance space, and the practicability is high.

[0057] In this embodiment, a accommodating cavity 321 is provided on the front side of the folding layer 32, and a cover body 322 is provided on the front side cover of the folding layer 32. The cover body 322 is used to close the accommodating cavity 321. The driving assembly includes a rotating block 332 and a driving member. The rotating block 332 is rotatably connected to the accommodating cavity 321. The outer periphery of the rotating block 332 is provided with driving teeth 3321 along the circumferential direction. The telescopic rod 331 is located in the accommodating cavity 321. One end of the telescopic rod 331 is provided with meshing teeth 3311 along the length direction, and the meshing teeth 3311 are meshed with the driving teeth 3321. The driving member is used to drive the rotating block 332 to rotate. When the rotating block 332 rotates, it can drive the other end of the telescopic rod 331 to extend out of the side wall of the folding layer 32 or retract into the folding layer 32.

[0058] Since the side wall of one end of the telescopic rod 331 is provided with an engaging tooth 3311 along the length direction, the rotating block 332 is rotatably connected to the accommodating cavity 321, and the outer periphery of the rotating block 332 is provided with a driving tooth 3321 along the circumferential direction, and the engaging tooth 3311 is engaged with the driving tooth 3321, so that when the driving member drives the rotating block 332 to rotate, the telescopic rod 331 can be driven to move laterally. When the other end of the telescopic rod 331 extends from the accommodating cavity 321 to the outside of the side wall of the folding layer 32, the end of the telescopic rod 331 can enter between the locking teeth 41 of the guide rail 4 to lock the folding layer 32. When the other end of the telescopic rod 331 is retracted into the accommodating cavity 321, the folding layer 32 is unlocked from the guide rail 4, so that the position of the folding layer 32 can be adjusted.

[0059] Preferably, the upper and lower parts of the side of the cover body 322 facing the folding layer 32 are provided with buckles 323, and the upper side wall and the lower side wall in the accommodating cavity 321 are provided with snap-in slots 324 for the buckles 323 to be inserted, so that the cover body 322 can be conveniently covered on the front side of the folding layer 32, which is convenient for installation and maintenance.

[0060] Furthermore, the driving member includes a driving button 333, a connecting piece 334 and an elastic member 335. The elastic member 335 is arranged in the accommodating cavity 321 to continuously apply a force to the telescopic rod 331 to move outward from the folding layer 32. One end of the driving button 333 is located in the accommodating cavity 321, and the other end of the driving button 333 extends out of the folding layer 32. One end of the connecting piece 334 is connected to the outer periphery of the rotating block 332, and the other end of the connecting piece 334 is connected to one end of the driving button 333 located in the accommodating cavity 321, so that when the driving button 333 is pressed, the rotating block 332 is driven to rotate, so as to drive the end of the telescopic rod 331 to retract into the accommodating cavity 321.

[0061] Since the elastic member 335 continuously applies force to the telescopic rod 331 to move outward from the folding layer 32, when the user does not press the driving button 333, the elastic member 335 pushes the end of the telescopic rod 331 to be clamped between the latch teeth 41 of the guide rail 4 to lock the folding layer 32. When the user presses the driving button 333, the elastic force of the elastic member 335 can be overcome and the rotating block 332 can be driven to rotate, so that the end of the telescopic rod 331 can be withdrawn from between the latch teeth 41 of the guide rail 4 and retracted into the accommodating cavity 321, so as to achieve the unlocking of the folding layer 32 and the guide rail 4, so that the folding layer 32 can be adjusted in the front and rear directions.

[0062] Furthermore, one end of the driving button 333 is located in the accommodating cavity 321, and the other end of the driving button 333 extends downward to the bottom of the folding layer 32. Since the accommodating cavity 321 is located on the front side of the folding layer 32, the driving button 333 is located below the front end of the folding layer 32, so that when the user grasps the front end of the folding layer 32, the driving button 333 can be pressed, thereby facilitating the adjustment of the position of the folding layer 32.

[0063] In this embodiment, the elastic member 335 is a torsion spring, and the torsion spring coil is arranged on the outer periphery of the rotating block 332. One end of the torsion spring abuts against the inner wall of the accommodating cavity 321, and the other end of the torsion spring is fixed to the rotating block 332 to continuously apply torque to the rotating block 332, so that the rotating block 332 continuously applies force to the telescopic rod 331 to move outward.

[0064] Specifically, the driving tooth 3321 is provided on the outer periphery of one end of the rotating block 332, and the other end of the rotating block 332 is provided with a mounting ring 3322. The torsion spring is sleeved on the outer periphery of the mounting ring 3322. The side of the accommodating cavity 321 facing the outside of the refrigerating chamber 11 is provided with a rotating shaft 325. The rotating block 332 is sleeved outside the rotating shaft 325 and can rotate around the rotating shaft 325. Therefore, through the setting of the torsion spring, after the user stops pressing the driving button 333, the torsion spring can drive the rotating block 332 to rotate around the rotating shaft 325 and reset, so that the driving tooth 3321 of the rotating block 332 pushes the telescopic rod 331 to move outside the accommodating cavity 321.

[0065] Preferably, an abutment block 3312 is provided on the telescopic rod 331 , and a stopper 326 for stopping the abutment block 3312 is provided on the inner wall of the accommodating cavity 321 to limit the engagement teeth 3311 of the telescopic rod 331 from disengaging from the driving teeth 3321 of the rotating block 332 .

[0066] Since the torsion spring can continuously allow the rotating block 332 to push the telescopic rod 331 to move out of the accommodating chamber 321, in order to prevent the meshing teeth 3311 on the telescopic rod 331 from disengaging from the driving teeth 3321 of the rotating block 332, a stopper 326 for stopping the abutting block 3312 is provided on the inner wall of the accommodating chamber 321, thereby limiting the telescopic rod 331 from continuously moving out of the accommodating chamber 321, and thus the meshing teeth 3311 on the telescopic rod 331 will not disengage from the driving teeth 3321 of the rotating block 332.

[0067] In this embodiment, a limiting ridge 327 is provided on the inner wall of the accommodating cavity 321. The limiting ridge 327 is extended in the transverse direction. A guide channel is formed between the limiting ridge 327 and the inner wall of the accommodating cavity 321. The telescopic rod 331 is located in the guide channel.

[0068] By setting the limiting convex strip 327, a guide channel is formed between the limiting convex strip 327 and the inner wall of the accommodating cavity 321, so as to guide the telescopic rod 331 so that the telescopic rod 331 can move stably in the lateral direction.

[0069] In this embodiment, the side of the latch 41 facing the outside of the refrigerating chamber 11 is a first curved surface 42, the side of the latch 41 facing the inside of the refrigerating chamber 11 is a first plane 43, the side of the end of the telescopic rod 331 extending out of the folding layer plate 32 facing the outside of the refrigerating chamber 11 is a second plane 3313, and the side of the end of the telescopic rod 331 extending out of the folding layer plate 32 facing the inside of the refrigerating chamber 11 is a second curved surface 3314.

[0070] When the end of the telescopic rod 331 is inserted between two adjacent latch teeth 41 on the guide rail 4, the second arc surface 3314 of the end of the telescopic rod 331 is opposite to the first arc surface 42 of the latch teeth 41, so that the first arc surface 42 of the latch teeth 41 cannot completely block the end of the telescopic rod 331. When the user needs to adjust the position of the folding layer plate 32 toward the refrigerator compartment 11, the user can directly apply force to push the folding layer plate 32 to move into the refrigerator compartment 11, so that the end of the telescopic rod 331 By moving along the first curved surface 42 of the latch tooth 41, the folding layer 32 is moved into the cold storage room 11. At the same time, since the second plane 3313 of the telescopic rod 331 is opposite to the first plane 43 of the latch tooth 41, the folding layer 32 can be limited from being pulled out of the cold storage room 11. The user cannot directly pull the folding layer 32 to adjust the position of the folding layer 32, and can only drive the end of the telescopic rod 331 to withdraw from between the latch teeth 41 of the guide rail 4 through the driving assembly before pulling the folding layer 32 outward.

[0071] In other embodiments, the side of the latch 41 facing the outside of the refrigerating chamber 11 is a third plane, the side of the latch 41 facing the inside of the refrigerating chamber 11 is a third curved surface, the side of the end of the telescopic rod 331 extending out of the folding layer plate 32 facing the outside of the refrigerating chamber 11 is a fourth curved surface, and the side of the end of the telescopic rod 331 extending out of the folding layer plate 32 facing the inside of the refrigerating chamber 11 is a fourth plane.

[0072] When the end of the telescopic rod 331 is inserted between two adjacent latch teeth 41 on the guide rail 4, the fourth arc surface of the end of the telescopic rod 331 is opposite to the third arc surface of the latch teeth 41, so that the third arc surface of the latch teeth 41 cannot completely block the end of the telescopic rod 331. When the user needs to adjust the position of the folding layer plate 32 to the outside of the refrigerator chamber 11, the user can directly apply force to pull the folding layer plate 32 to move outside the refrigerator chamber 11, so that the end of the telescopic rod 331 By moving along the third curved surface of the latch tooth 41, the folding layer 32 is moved out of the cold storage chamber 11. At the same time, since the fourth plane of the telescopic rod 331 is opposite to the third plane of the latch tooth 41, the folding layer 32 can be limited from being pushed into the cold storage chamber 11. The user cannot directly push the folding layer 32 to adjust the position of the folding layer 32, and can only drive the end of the telescopic rod 331 to withdraw from between the latch teeth 41 of the guide rail 4 through the driving assembly before pushing the folding layer 32 inward.

[0073] It should be noted that, although the end of the telescopic rod 331 can also be adjusted in a single direction after being inserted between the teeth 41 of the guide rail 4, the end of the telescopic rod 331 can continue to be pressed against the teeth 41 of the guide rail 4 under the action of the torsion spring, so the user needs to apply a certain force to push or pull the folding layer 32 to drive the folding layer 32 to move. If the user does not apply force to intervene, the folding layer 32 can maintain its position unchanged, so the folding layer 32 in this state is also considered to be in a locked state.

[0074] Furthermore, as long as one of the ends of the telescopic rod 331 and the latch 41 has a curved surface on its side, a one-way locking effect can be achieved without both having curved surfaces. The ends of the telescopic rod 331 and the latch 41 both have curved surfaces, which makes it easier for the user to directly push or pull the folding plate 32 to move and adjust the position. Moreover, the curved surface is only one of the preferred implementations, and an inclined guide surface can also achieve a one-way locking effect between the folding plate 32 and the guide rail 4.

[0075] In this embodiment, the ribs 12 include an upper rib 121 and a lower rib 122, both of which are extended along the front-to-back direction of the box body 1, and the upper rib 121 is located relatively above the lower rib 122, and the side edges of the fixed layer plate 31 and the folding layer plate 32 enter between the upper rib 121 and the lower rib 122, thereby stably connecting the fixed layer plate 31 and the folding layer plate 32 in the cold storage chamber 11 of the box body 1. A supporting rib 123 is further provided on the upper part of the rear area of ​​the lower rib 122, so that the side of the fixed layer plate 31 is located between the upper rib 121 and the supporting rib 123, and the side of the folding layer plate 32 enters between the upper rib 121 and the lower rib 122, so that the height of the fixed layer plate 31 is higher than the folding layer plate 32, and then the folding layer plate 32 can be stored directly under the fixed layer plate 31. At the same time, because the distance between the front area of ​​the upper rib 121 and the lower rib 122 is smaller than the distance between the rear area of ​​the upper rib 121 and the lower rib 122, the fixed layer plate 31 is restricted between the rear area of ​​the upper rib 121 and the lower rib 122, and the fixed layer plate 31 cannot be moved forward, thereby fixing the position of the fixed layer plate 31. The guide rail 4 is fixed between the front areas of the upper bile rib 121 and the lower bile rib 122 by bolts, so that the cooperation between the folding layer plate 32 and the guide rail 4 can realize the stepless adjustment of the folding layer plate 32 .

[0076] The utility model also relates to a refrigerator, comprising:

[0077] The box body 1 has a refrigerating chamber 11 therein, and ribs 12 are arranged on opposite sides of the refrigerating chamber 11, and the ribs 12 are extended along the front-back direction.

[0078] The door body 2 is hinged to the box body 1 to open or close the refrigerating chamber 11.

[0079] The shelf 3 includes a fixed shelf 31, a folding shelf 32 and a locking mechanism 33. The fixed shelf 31 and the folding shelf 32 are both connected between the ribs 12 on both sides of the refrigerating chamber 11, and the folding shelf 32 is located below the fixed shelf 31. The folding shelf 32 can move in the front-to-back direction. The locking mechanism 33 includes a telescopic rod 331 and a driving assembly both provided in the folding shelf 32. Two telescopic rods 331 are provided, and the driving assembly is used to drive the ends of the two telescopic rods 331 to extend from the two side walls of the folding shelf 32 or retract into the folding shelf 32 in a one-to-one correspondence.

[0080] The guide rail 4 is provided with two guide rails 4, and the two guide rails 4 are located at the ribs 12 on opposite sides of the refrigerating chamber 11 in a one-to-one correspondence. The guide rail 4 is extended along the front-to-back direction, and the guide rail 4 is provided with a plurality of latch teeth 41 for the telescopic rod 331 to enter at intervals along the length direction.

[0081] After the driving assembly drives the telescopic rod 331 to extend from the side wall of the folding layer 32 and be clamped between the clamping teeth 41 of the guide rail 4, the folding layer 32 can be restricted from moving in the front-rear direction.

[0082] Specifically, the two telescopic rods 331 are correspondingly located above and below the rotating block 332 of the driving assembly, and the meshing teeth 3311 on the two telescopic rods 331 are meshed with the driving teeth 3321 of the rotating block 332, so that when the rotating block 332 rotates, the two telescopic rods 331 can be driven to move synchronously in the lateral direction, thereby synchronously driving the ends of the two telescopic rods 331 to extend from the two side walls of the folding layer 32 and enter between the locking teeth 41 of the two guide rails 4, or synchronously driving the ends of the two telescopic rods 331 to retract into the accommodating cavity 321 to release the lock of the folding layer 32 and the guide rail 4.

[0083] The working principle of the utility model is:

[0084] During normal use, the folding layer 32 is completely extended from under the fixed layer 31 to achieve the maximum support space between the folding layer 32 and the fixed layer 31. When it is necessary to store items of a certain height such as bottles, the folding layer 32 can be pushed under the fixed layer 31 according to the size of the items to reasonably form sufficient avoidance space for the items to stand upright in the refrigerator compartment 11, thereby making the storage space of the refrigerator more reasonable and convenient, and maximizing the use of the space in the refrigerator compartment 11 of the refrigerator. Then, when the position of the folding layer plate 32 needs to be adjusted, the user needs to hold the folding layer plate 32 with his hand and, at the same time, press the driving button 333 with his finger to overcome the elastic force of the torsion spring, thereby driving the rotating block 332 to rotate, allowing the driving tooth 3321 of the rotating block 332 to drive the telescopic rod 331 to move laterally, allowing the end of the telescopic rod 331 that passes through the accommodating cavity 321 of the folding layer plate 32 to withdraw from between the latch teeth 41 on the guide rail 4 and retract into the accommodating cavity 321, completing the unlocking between the folding layer plate 32 and the guide rail 4, and then the folding layer plate 32 can be moved to the inside or outside of the refrigerating chamber 11 at will to adjust the position. After the user moves the folding layer plate 32 to a reasonable position, release the grip of the folding layer plate 32 and release the grip of the folding layer plate 32. The finger of the layer plate 32 is released, and the driving button 333 is released. At this time, under the action of the torsion spring, the rotating block 332 can be driven to rotate and reset, so that the driving tooth 3321 on the rotating block 332 can push the telescopic rod 331 to move laterally, so that the end of the telescopic rod 331 extends from the accommodating cavity 321 of the folding layer plate 32 to the outside of the side wall of the folding layer plate 32, and the end of the telescopic rod 331 is stuck between the teeth 41 of the guide rail 4 to achieve the locking of the telescopic rod 331 and the guide rail 4, and under the continuous force of the torsion spring, the end of the telescopic rod 331 can be pressed against the teeth 41 of the guide rail 4 to ensure that the end of the telescopic rod 331 is not easily moved at will, thereby ensuring the stability of the position of the folding layer plate 32.

[0085] In summary, the utility model provides a refrigerator, which has a plurality of latch teeth evenly distributed along the length direction of the guide rail, and controls the telescopic rod to enter or withdraw from between the latch teeth through a driving component, thereby realizing locking or unlocking of the folding layer and the guide rail, and then realizing stepless adjustment of the folding layer, which is convenient for users to use and has high practicality.

[0086] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
