According to an embodiment of the present application, referring to fig. 12 and 14, the shelf member 30 includes a shelf 31 and a suspension 32. The shelf 31 has a shelf body 34 and a support plate 35. The two support plates 35 are respectively arranged at the bottoms of the left end and the right end of the layer frame body 34, and the support plates 35 and the layer frame body 34 can be connected through screws.

The suspension 32 is connected to the rear end of the support plate 35; the support plate 35 is provided with a hook 351, the suspension 32 is provided with a first hanger 36, and the hook 351 is hung on the first hanger 36.

In this application, the suspension end of the suspension device 40, the matching position of the lifting guide rail 60 and the layer frame component 30 are all located on the suspension 32 at the rear end of the layer frame 31, so that the connection structure on the layer frame component 30 is centralized, and the problem that the storage space is occupied when the connection structure is arranged at other positions of the layer frame component 30 is avoided.

When the user is lifting the shelf 31, the gravity of the shelf component 30 and the gravity of the articles thereon need to be overcome, and the rotary knob 54 is laborious, so that the power assisting device is added to the shelf component 30, and the problem of laborious adjustment of the shelf 31 by the user is solved.

In some embodiments of the present application, referring to fig. 15, the refrigerator further includes a constant force spring 70. The constant force spring 70, i.e., a coil spring, has approximately the same elastic force over a longer distance after a certain distance of the coil spring is extended, and thus the constant force spring 70 can provide a constant pulling force to the outside.

A constant force spring 70 is attached to the rear sidewall of the tank 11 above the shelf member 30. The free end of the constant force spring 70 extends downwardly and is connected to the shelf member 30.

In the present example, the constant force spring 70 has two, each connected to the suspension 32. In other embodiments, one, or three or more constant force springs 70 may be provided.

The sum of the elastic forces of all the constant force springs 70 is slightly smaller than the gravity of the shelf component 30, so that the shelf 31 can hover at will when in no load, and when the height of the shelf 31 is adjusted by a user, the acting force applied by the user to the knob can be relieved due to the tensile force action of the constant force springs 70 on the shelf component 30, and the aim of adjusting can be fulfilled by using smaller force.

According to the embodiment of the present application, the rear end of the suspension 32 is provided with a bent assistance connecting portion 321. The power-assisted connection portion 321 on the left suspension 32 extends rightward, and the power-assisted connection portion 321 on the right suspension 32 extends leftward. The free end of the constant force spring 70 may be connected to the assistance connecting part 321 by a screw.

According to the first conception, the layer frame component 30 is lifted by the suspension device 40, the lifting of the layer frame component 30 is regulated by the regulating device 50, the regulating device 50 comprises the knob 54 and the rack 51, the spiral portion 541 of the knob 54 is matched with the rack 51, so that the rotary motion of the knob 54 is converted into linear motion of the rack 51, the suspension device 40 is retracted and released, the purpose of regulating the height of the layer frame component 30 is achieved, and any hovering of the layer frame component 30 in the stroke range is achieved.

In the second concept of the present application, the height of the shelf member 30 can be adjusted by manually rotating the knob 54, so that the cost of the present application is relatively low compared with the high cost caused by electric lifting in the prior art, and the present application can be widely popularized and used.

The third concept of the present application is that the height of the shelf member 30 can be adjusted by manually rotating the knob 54, which omits the motor and has the advantage of small occupied space compared with the problem that the motor occupies the space of the storage room when the electric lifting structure is adopted in the prior art.

The fourth concept of the present application improves convenience in disassembly and cleaning of the shelf 31 because the hanging end of the hanging device 40 is connected to the hanger 32 while the shelf 31 is hung from the hanger 32, and the shelf 31 is easily separated from the hanger 32.

The fifth concept of the present application, because of the constant force spring 70 for hanging the shelf member 30, provides a pulling force for the shelf member 30 by the constant force spring 70, can alleviate the acting force of manual adjustment, and has the advantage of portability of manual adjustment.
