Where nothing contrary is intended, use of the directional phrases such as "inner and outer" is intended to refer to the inner and outer relative to the contours of the component or structure itself. In addition, it should be noted that terms such as "first", "second", and the like are used for distinguishing one element from another, and have no order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings denote the same elements.

In particular embodiments provided by the present disclosure, a refrigerator is provided. Referring to fig. 1 to 9, the refrigerator includes an inner container 100, a partition assembly 200, and a temperature adjusting device, the inner container 100 having a storage space 110 and an opening communicating with the storage space 110, the partition assembly 200 being configured to be detachably coupled with the inner container 100, the storage space 110 being capable of forming a temperature varying region 400 and a cooling region 700 separately by the partition assembly 200 when the partition assembly 200 is coupled in the inner container 100, the temperature varying region 400 communicating with the cooling region 700 after the partition assembly 200 is detached from the inner container 100, the partition assembly 200 including a first heat insulating layer 210 for blocking the temperature varying region 400 from heat exchanging with the cooling region 700, the temperature adjusting device for adjusting the temperature of the temperature varying region 400.

Through the above technical solution, when the partition assembly 200 is installed in the inner container 100, the independent temperature changing region 400 and the independent cooling region 700 can be formed in the storage space 110, so as to flexibly adjust the temperature at which the food material is stored; after the partition plate assembly 200 is detached from the inner container 100, the temperature-variable region 400 and the cooling region 700 can be communicated, at this time, the whole storage space 110 can be used as both the cooling region 700 and the temperature-variable region 400, and meanwhile, as the temperature-variable region 400 is communicated with the cooling region 700, food materials with a larger volume can be stored, so that the use is more convenient. In addition, the separator assembly 200 includes the first insulation layer 210, which can effectively block the heat exchange between the variable temperature region 400 and the cold storage region 700. In addition, the variable temperature region 400 is selectively formed in the storage space 110, enabling optimization of the storage space. Therefore, the refrigerator provided by the present disclosure can selectively form the temperature varying region 400 in the storage space 110, and can flexibly use the entire storage space 110 by disassembling and assembling the partition plate assembly 200, so that the use is more convenient, and the storage space can be optimized.

The refrigerator further includes a cabinet door (not shown) disposed at an opening side of the inner container 100 to openably and closably seal the storage space 110 of the inner container 100.

Baffle assembly 200 may be removably attached to bladder 100 in any suitable manner depending on the needs of the application. For example, in some embodiments, as shown in fig. 1, the inner container 100 is provided with a first guide structure 300 for inserting or extracting the baffle assembly 200 into or from the storage space 110 from the opening side of the inner container 100, so as to guide the movement of the baffle assembly 200 through the first guide structure 300, thereby achieving the detachable connection with the inner container 100.

Thus, according to practical application requirements, for example, when a large amount of food materials need to be stored in the temperature varying region 400, the partition plate assembly 200 may be matched with different first guide structures 300 to increase the space in the temperature varying region 400. Similarly, when the smaller temperature-varying region 400 can meet the requirement, the space of the temperature-varying region 400 can also be reduced. Therefore, by the mode, the use requirements of customers can be met more easily, and the user experience is optimized.

The first guide structure 300 may be configured in any suitable manner, for example, as shown in fig. 5, the first guide structure 300 includes two first guide grooves 310 respectively disposed on two side walls of the inner container 100 opposite with respect to the longitudinal direction, the first guide grooves 310 extend in the transverse direction and have first insertion holes 320 at one end near the open side of the inner container 100, two opposite side edges of the baffle assembly 200 can be respectively received in the two first guide grooves 310, and the baffle assembly 200 can be inserted into or pulled out from the first insertion holes 320 along the first guide grooves 310, wherein the longitudinal direction is a vertical direction and is perpendicular to the transverse direction.
