Optionally, the heat collecting bin 300 is disposed at the top inside the enclosure 100, the fresh food keeping bin 110 is disposed below the heat collecting bin 300, the cold storage bin is disposed below the fresh food keeping bin 110, and the heat preservation bin 310 is disposed below the enclosure 100. A compressor 301 support and a condenser support are arranged in the heat collecting bin 300 and are respectively used for installing the compressor 301 and the condenser 302. The bottom area of the heat preservation bin 310 is slightly smaller than that of the machine shell 100, so that the occupied area of the refrigerator is reduced. And the refrigerator can reduce the installation space when being hung and installed on the wall.

In some embodiments, as shown in fig. 2 and 3, the refrigerator further includes a rotation assembly and a reset assembly. The fresh food compartment 110 is rotated by the rotating assembly to extend outside the housing 100 and is reset to an initial position by the reset assembly.

Under the action of the hinge portion 200, the fresh food compartment 110 can rotate relative to the first end of the hinge portion 200, and does not need to horizontally slide for a certain distance and then rotate. When the fresh food compartment 110 is extended to the outside of the housing 100 by rotation, it is convenient for the user to access the food therein. Under the effect of the reset portion 210, the reset portion 210 pulls the hinge portion 200 after the fresh-keeping bin 110 is used, and drives the fresh-keeping bin 110 to reset to the initial position, without the need for the user to push the fresh-keeping bin 110 back to the initial position along the extended moving path. Thereby making the fresh-keeping bin 110 have higher flexibility and more convenient to use.

Optionally, the reset portion 210 includes a pneumatic lever. The telescopic end 211 of the pneumatic rod is connected to the hinge part 200 and the fixed end 212 is hinged to the cabinet 100.

When the telescopic end 211 extends to the maximum distance, the pneumatic rod is locked automatically. After the preservation bin 110 is used, the user pushes the preservation bin 110 by using a pushing force larger than the preset pressure of the pneumatic rod, the telescopic end 211 automatically contracts and pulls the hinge part 200 to rotate, and the hinge part 200 drives the preservation bin 110 to synchronously move. When the telescopic end 211 is retracted to a minimum distance, the fresh food compartment 110 is reset to the initial position, and the pneumatic rod is locked by itself. When the fresh-keeping bin 110 is reused, the fresh-keeping bin 110 is pulled out of the casing 100 by a pulling force which is larger than the preset pressure of the pneumatic rod.

Optionally, a handle 230 is provided at the lower portion of the fresh food compartment 110. The user holds and pulls the handle 230 outward of the housing 100 to rotate the fresh food compartment 110 downward to the farthest position, and pushes the handle 230 inward of the housing 100 to return the fresh food compartment 110 to the initial position.

Optionally, the refrigerator further comprises a prompting component for giving a prompt when the fresh food compartment 110 is rotated to the farthest position. After receiving the prompt, the user knows that the fresh keeping bin 110 cannot continuously extend outwards through rotation, and the situation that the user continuously pulls the fresh keeping bin 110 to damage the structures of the hinge rod part 200 and the reset part 210 is avoided.

Further optionally, the prompting assembly includes a distance measuring device and a prompting device. The distance measuring device includes a distance sensor for detecting positional information of the fresh food compartment 110. The prompting device comprises an indicating controller and an indicating lamp, wherein the indicating controller is electrically connected with the distance sensor and the indicating lamp. When the distance sensor detects that the position information of the fresh-keeping bin 110 is the farthest position, the indicating controller controls the indicator lamp to light up, so that a prompt is given to a user.

Optionally, the hinge portion 200 comprises one hinge rod, i.e. one hinge rod is disposed on each side of the fresh food compartment 110. The hinge rods are configured as strip-shaped plate structures and are arranged opposite to one another.

Alternatively, the hinge part 200 includes a plurality of hinge bars, and the plurality of hinge bars are arranged in parallel with each other. For example, the hinge part 200 includes two hinge rods, that is, two hinge rods are respectively disposed at both sides of the fresh food compartment 110, and the hinge rods at both sides are disposed opposite to each other two by two.

Optionally, the cabinet 100 includes a connection plate 220, and the connection plate 220 is positioned corresponding to the hinge lever part 200 such that the first end of the hinge lever part 200 is hinged to the connection plate 220.

Further, optionally, the guide assembly comprises a slide and a runner. Wherein the sliding block is arranged on the outer side wall of the fresh-keeping bin 110, and the sliding groove corresponds to the sliding block and is arranged on the inner side wall of the casing 100 along the rotating track of the fresh-keeping bin 110. And the sliding block and the sliding groove form sliding fit connection, and the sliding block slides in the sliding groove when the preservation bin 110 rotates, so that the rotation direction of the preservation bin 110 is guided, and the rotation of the preservation bin 110 is smoother.

In some embodiments, as shown in fig. 4 and 5, the refrigerator further comprises a vacuum assembly. The vacuum assembly includes a vacuum valve 120 and a vacuum pump 130. The vacuum valve 120 is disposed on a sidewall of the fresh-keeping bin 110, and an air inlet 121 of the vacuum valve 120 is communicated with an inside of the fresh-keeping bin 110 and an air outlet 122 is communicated with an outside of the fresh-keeping bin 110. The vacuum pump 130 is disposed in the cabinet 100, and the suction port 131 of the vacuum pump 130 is disposed opposite to the air outlet 122 of the vacuum valve 120. When the fresh food compartment 110 is moved to the sealing position, the air outlet 122 of the vacuum valve 120 is abutted against the air inlet 131 of the vacuum pump 130, so that the vacuum pump 130 pumps the air in the fresh food compartment 110.

The vacuum valve 120 moves synchronously with the fresh food compartment 110, when the fresh food compartment 110 moves to a sealing position, the air outlet 122 of the vacuum valve 120 is butted with the air suction port 131 of the vacuum pump 130, and the vacuum pump 130 is started after the butting so as to vacuumize the fresh food compartment 110. This eliminates the need for lengthy vacuum lines and saves a large amount of installation space in the partition wall of the cabinet 100.

The manner of movement of the crisper bin 110 here includes rotation of the crisper bin 110 relative to the first end of the hinge portion 200, the sealing position and the initial position being the same position. Thus, when the fresh food compartment 110 is rotated to the initial position, i.e., the sealing position, by the restoring portion 210, the air outlet 122 of the vacuum valve 120 is abutted against the air inlet 131 of the vacuum pump 130.

The side wall of the fresh-keeping bin 110, which is far away from the refrigerator door body, is recessed inwards to form a mounting groove 112, and the vacuum valve 120 is arranged in the mounting groove 112. The casing 100 has a mounting plate 140, and the mounting plate 140 is adapted to the mounting groove 112 for mounting the vacuum pump 130. When the fresh food compartment 110 is rotated to the sealing position, the portion of the mounting plate 140 where the vacuum pump 130 is mounted is located in the mounting groove 112, so that the air outlet 122 of the vacuum valve 120 and the air inlet 131 of the vacuum pump 130 are conveniently abutted.

Alternatively, the inner diameter of the air outlet 122 is equal to the outer diameter of the air inlet 131, so that the outer wall of the air inlet 131 is tightly attached to the inner wall of the air outlet 122 when the air outlet 122 of the vacuum valve 120 and the air inlet 131 of the vacuum pump 130 are butted. This improves the sealing of the vacuum assembly.

Alternatively, the inner diameter of the suction port 131 is equal to the outer diameter of the air outlet 122, so that the outer wall of the air outlet 122 is closely attached to the inner wall of the suction port 131 when the air outlet 122 of the vacuum valve 120 and the suction port 131 of the vacuum pump 130 are butted. This improves the sealing of the vacuum assembly.

The second fan 331 is disposed in the second air duct 330 for blowing heat of the compressor 301 to the external environment. In this way, the heat dissipated from the heat collecting bin 300 by the compressor 301 can be recovered to the heat preserving bin 310 through the first air duct 320, and can also be dissipated to the external environment through the second air duct 330.

Still further, optionally, the heat conduction assembly further comprises a control portion. The control unit is used for controlling the first fan 321 or the second fan 331 to be turned on according to the temperature of the heat-preserving chamber 310. When the first fan 321 is turned on, the heat of the heat collecting bin 300 is conducted to the heat insulating bin 310, and when the second fan 331 is turned on, the heat of the heat collecting bin 300 is conducted to the external environment.

Still further, optionally, the control portion includes a temperature measuring device and a fan controller. The temperature measuring device comprises a first temperature sensor, and the first temperature sensor is used for detecting the temperature of the heat preservation bin 310. The fan controller is electrically connected to the first temperature sensor, the first fan 321, and the second fan 331. When the temperature of the heat preservation bin 310 is lower than the preset temperature, the fan controller controls the first fan 321 to be turned on and the second fan 331 to be turned off, and the heat of the compressor 301 is transferred to the heat preservation bin 310 through the first air duct 320, so that the heat preservation bin 310 reaches the preset temperature to play a role in heat preservation of food. When the temperature of the heat preservation bin 310 is higher than the preset temperature, the fan controller controls the first fan 321 to be closed and the second fan 331 to be opened, and the heat of the compressor 301 is conducted to the external environment through the second air duct 330, so that the food is prevented from being damaged due to the overhigh temperature of the heat preservation bin 310, and the effect of cooling the compressor 301 is achieved.

After the heat in the thermal insulation chamber 310 is diffused to the external environment through the first small hole 411, the internal and external temperatures of the thermal insulation chamber 310 are gradually balanced, and the mist on the double-layer transparent side wall is gradually eliminated. Moreover, when the temperature difference between the inside and the outside of the heat preservation bin 310 is large, the shielding area of the adjusting part 420 is reduced, so that the area of the hole opening of the first small hole 411 in the gap is increased, the temperature inside and the temperature outside the heat preservation bin 310 are rapidly balanced, and the mist on the double-layer transparent side wall is rapidly eliminated; when the temperature difference between the inside and the outside of the thermal insulation bin 310 is small, the shielding area of the adjusting part 420 is increased to reduce the area of the orifice of the first small hole 411 in the gap, so that the mist can be eliminated and the heat loss of the thermal insulation bin 310 can be prevented from being too fast.

Optionally, the adjustment part 420 includes a baffle. The plate surface of the baffle plate is provided with a plurality of second small holes 421, and the baffle plate is movably arranged in the gap; the arrangement and size of the second small holes 421 and the first small holes 411 disposed on the inner wall plate 400 are the same, so that the baffle can completely block or completely avoid the openings of the first small holes 411.

The first small holes 411 on the inner wall plate 400 and the outer wall plate 410 are opposite to each other, and the second small holes 421 of the baffle plate are the same as the first small holes 411 of the inner wall plate 400 in arrangement and size. Thus, when the baffle is moved to make the second small hole 421 coincide with the first small hole 411, the baffle completely avoids the opening of the first small hole 411, and the area of the first opening is the largest at this moment; when the baffle is moved to make the second small hole 421 and the first small hole 411 partially dislocated, the part of the baffle, which is not provided with the second small hole 421, shields part of the opening of the first small hole 411; when the baffle is moved to make the second small hole 421 and the first small hole 411 completely dislocate each other, the part of the baffle not provided with the second small hole 421 completely covers the opening of the first small hole 411, and the area of the first opening is the smallest at this moment.

Optionally, the refrigerator further comprises a temperature detection device, wherein the temperature detection device comprises a second temperature sensor for detecting the temperature inside the heat preservation chamber 310 and a third temperature sensor for detecting the temperature outside the heat preservation chamber 310. This facilitates the user to reasonably move the position of the baffle according to the internal and external temperatures of the thermal insulation chamber 310, thereby adjusting the area of the first orifice in the gap.

Optionally, one side of the panel abuts the outer panel 410 and the other side abuts the inner panel 400. Thus, when the heat of the insulation bin 310 is diffused to the external environment through the first small holes 411 of the inner wall plate 400, the second small holes 421 of the baffle and the second small holes 421 of the outer wall plate 410 in sequence, the heat is not diffused into the gap, and the mist is prevented from being generated on the side, located in the gap, of the inner wall plate 400 and the outer wall plate 410.

Optionally, the baffle is made of transparent material to prevent the sight of observing the inside of the heat preservation chamber from being blocked.

Optionally, the dual layer transparent sidewall comprises a glass sidewall or an acrylic sidewall.

Optionally, the barrier is provided with a push-pull portion for moving the barrier.

Further, optionally, the push-pull portion comprises a push-pull block and a push-pull groove. Wherein the push-pull block is arranged at one side of the baffle plate facing the outer wall plate 410; the push-pull groove is arranged on the outer wall plate 410 corresponding to the push-pull block along the moving direction of the baffle plate; the push-pull block may be in a sliding fit with the push-pull slot, and a portion of the push-pull block may extend through the push-pull slot and beyond the outer wall plate 410 for easy handling. The baffle can move left and right in the gap, and the push-pull groove is arranged on the outer wall plate 410 along the left and right direction. The user holds the part of the push-pull block extending out of the outer wall plate 410, slides the push-pull block left and right along the push-pull groove, and the push-pull block drives the baffle to move left and right synchronously, so that the baffle can be moved conveniently.

Optionally, the defogging assembly further includes a heating portion. The heating part is used for heating the double-layer transparent side wall to remove the fog. Under heating portion and micropore portion combined action, the efficiency of defogging has been improved.

Further, alternatively, the heating part includes heating wires embedded in the inner and outer wall plates 400 and 410, and the heating wires heat the inner and outer wall plates 400 and 410 when energized. As the temperature of the inner and outer wall panels 400 and 410 increases, the surface haze is gradually eliminated.

In some embodiments, as shown in fig. 9, the refrigerator further includes a condensate water assembly. The condensed water assembly comprises a confluence part 500 and an exhaust part 510, wherein the confluence part 500 is used for converging condensed water in the heat preservation bin 310, and the confluence part 500 is arranged opposite to the second end of the first air channel 320, so that the converged condensed water is heated and gasified by heat of a heat source; the exhaust portion 510 is disposed on a sidewall of the heat-preserving bin 310 and close to the confluence portion 500, so that the vaporized condensed water is discharged to the outside of the heat-preserving bin 310.

The heat diffused by the compressor 301 in the heat collecting bin 300 is conducted to the food to be heated in the heat preserving bin 310 through the first air duct 320 as a heat source, and during the process, the condensed water is gradually generated in the heat preserving bin 310 and is gathered to the confluence portion 500. Since the merging portion 500 is disposed opposite to the second end of the first air duct 320, the condensed water can be rapidly vaporized by heat of the heat source. The gasified condensed water is discharged to the outside of the heat preservation bin 310 under the action of the exhaust part 510, the condensed water in the heat preservation bin 310 is effectively treated, and the heating and heat preservation effects of the heat preservation bin 310 are guaranteed.

Optionally, a hot air inlet 311 is disposed at the top of the heat preservation chamber 310, and a second end of the first air duct 320 is communicated with the heat preservation chamber 310 through the hot air inlet 311. The confluence part 500 comprises a confluence groove arranged at the bottom of the heat preservation bin 310, and condensed water generated in the heat preservation bin 310 is converged in the confluence groove with a lower position at the bottom under the action of gravity. The converging tank is located below the second end, and the hot air from the first air duct 320 carries heat of the heat source and blows the condensed water in the converging tank downwards from the hot air inlet 311, so that the gasification rate of the condensed water is accelerated.

Further optionally, a drain hole is opened at the bottom of the confluence groove. In the case that the first air duct 320 is not blown out by hot air, the condensed water can be discharged to the outside of the thermal insulation bin 310 through the drain hole.

Optionally, the confluence part 500 further includes a tray 520 and a communication passage. The tray 520 is disposed in the heat-insulating chamber 310 for holding articles, and a surrounding edge is disposed around the tray 520 for receiving a certain amount of condensed water. One end of the communication channel is communicated with the bottom of the object placing disc 520, and the other end of the communication channel is communicated with the confluence groove; the height of the bottom of the object placing plate 520 is larger than that of the bottom of the flow converging groove, and the condensed water borne in the object placing plate 520 flows into the flow converging groove through the communicating channel under the action of gravity. The condensed water flowing into the reflux tank can be discharged out of the heat preservation bin 310 through heating and gasification, or can be directly discharged through a drain hole.

Optionally, the backflow groove is arranged on the bottom plate below the back plate of the heat preservation bin 310, and the confluence groove is close to the back plate; the reflux groove is arranged along the intersection line direction of the back plate and the bottom plate. The exhaust portion 510 includes a plurality of exhaust ports, and a plurality of exhaust holes are opened in the back plate along the extending direction of the bus duct. This enables the vaporized condensed water to be discharged out of the thermal insulation silo 310 in a short path.

Further, optionally, the exhaust portion 510 further includes an exhaust fan, and the exhaust fan is mounted on the surface of the back plate outside the heat preservation cabin 310 corresponding to the exhaust hole. The exhaust fan can accelerate the gasified condensed water to be discharged out of the heat preservation bin 310 from the exhaust hole when being started.
