Detailed Description
Fig. 1 is a schematic structural view of a refrigerator according to one embodiment of the present invention. Referring to fig. 1, a refrigerator 1 of the present invention includes a cabinet 10, a storage compartment 11 defined in the cabinet 10 for storing articles, at least one rack 12 detachably disposed in the storage compartment 11, and the at least one rack 12 dividing a space in the storage compartment 11 into at least two sub-spaces 111. In particular, the number of racks 12 may be one, which divides the space inside the storage compartment 11 into two sub-spaces. The number of racks 12 may be two, which divide the space inside the storage compartment 11 into three sub-spaces. Of course, the number of racks 12 may also be more than three. To facilitate the placement of the articles, the racks 12 are generally horizontally disposed within the storage compartment 11.
In particular, each rack 12 is provided with a display control device 20 corresponding to a corresponding subspace to display parameter information of the corresponding subspace and/or regulate and control parameters of the corresponding subspace. That is, the parameter regulation and control in each subspace are independent and do not influence each other. Parameters of the subspace 111 may include temperature, humidity, and the like. Also, the display control device 20 is electrically connected to the electric control device of the refrigerator 1 to allow signals to be transmitted between the display control device 20 and the electric control device and/or power to be supplied to the display control device 20 through the electric control device. The user can input the adjusting instruction of the corresponding subspace 111 through the display control device 20, and send the adjusting instruction to the electric control device through the display control device 20, and then the electric control device controls the air supply system of the refrigerator to realize the parameter adjustment in each subspace 111.
Because each rack 12 is provided with the display control device 20 corresponding to a corresponding subspace 111, parameter information such as temperature, humidity and the like of the corresponding subspace 111 can be clearly and intuitively displayed, and/or independent control of the parameters such as temperature, humidity and the like of the corresponding subspace independent of other subspaces 111 can be conveniently carried out, so that functions such as independent temperature control in a subarea and independent humidity control in a subarea can be conveniently realized in the storage compartment. The applicant sets the display control device 20 directly on the rack 12, no other additional structure is needed, the user can conveniently take and place the articles, and the display control device 20 does not affect the bearing function of the rack 12. In general, the user will not frequently replace the rack 12, and therefore, the rack 12 does not need to be frequently moved after being placed, and therefore, the electrical connection between the display control device 20 on the rack 12 and the electric control device of the refrigerator 1 does not need to be frequently disconnected and reconnected, thereby ensuring the long-term reliable and stable electrical connection between the display control device 20 and the electric control device, and further ensuring the good and stable partition display and partition regulation function in the refrigerator.
Specifically, the display control device 20 on each rack 12 may correspond to a sub-space 111 adjacently located on the rack 12 to better conform to the usage habits of the user. A drawer may be provided in the sub-space 111 below the lowermost rack 12. The display control device 20 may be fastened to the rack 12 by screws, bolts, or other suitable means, or may be fastened to the rack 12 by snapping or other suitable means.
In some embodiments, at least one parameter of each subspace having the corresponding display control device 20 is different from another parameter of each subspace controlled by the display control device 20, so as to achieve precise partition control in the storage compartment 11, thereby forming a plurality of storage spaces with different environments in the storage compartment 11. For example, when the temperature of the storage compartment 11 needs to be controlled in different zones, the display control device 20 on each rack 12 can control the temperature in each corresponding sub-space 111, so that storage environments with different temperatures are formed in each sub-space 111, and users can store food materials in different categories according to the characteristics of the food materials. For another example, when moisture control is required to be performed on the storage compartment 11 in a partitioned manner, the display control device 20 on each rack 12 can control the humidity in each corresponding sub-space 111, so that storage environments with different humidity are formed in each sub-space 111, and users can store the storage environments in a classified manner according to the characteristics of food materials. Of course, the two or more parameters of temperature and humidity in each sub-space 111 having the corresponding display control device 20 can be simultaneously different from each other by the display control device 20 on the corresponding rack 12.
Further, the refrigerator 1 also includes a split air supply system in fluid communication with each of the sub-spaces for controlled independent delivery of cooling air flow to each of the sub-spaces and for allowing return air in each of the sub-spaces to return to the evaporator compartment. Specifically, each subspace is provided with a respective air supply outlet and a respective air return inlet so as to independently control the temperature or humidity therein. Parameter adjustments within each subspace with a corresponding display control device 20 may be achieved by a split air supply system. Since the specific structure and operation principle of the branched air supply system are easily obtained by those skilled in the art, they are not described in detail herein.
