It can be understood that the sensing device on each storage layer corresponds to the storage layer 2, that is, the control unit can determine the storage layer 2 corresponding to the sensing device while receiving the load information sensed by the sensing device; meanwhile, the storage layer 2 and the driving device 5 are in corresponding relation, so that the control unit can control the driving device 5 corresponding to the storage layer 2 to start after obtaining the high-refrigeration-quantity demand area according to the load information, and the high-refrigeration-quantity demand area is refrigerated quickly and effectively in a targeted manner.

The structure of the driving device 5 is specifically described below by taking as an example that each air deflection plate group 4 includes two horizontal air deflection plates 41 rotatably connected to the upper and lower ends of the corresponding air outlet 3, but it should be understood that the structure of the driving device 5 is also applicable to an embodiment in which the air deflection plate group 4 includes two vertical air deflection plates rotatably connected to the left and right ends of the corresponding air outlet 3.
It can be understood that the cross air guiding plate 41 includes a cross air guiding plate body 411, and a cross rotating shaft 412 rotatably connecting the cross air guiding plate body 411 to the air outlet 3, and an axial hole matched with an end of the cross rotating shaft 412 is provided at the air outlet 3.
Referring to fig. 3-4, in the first embodiment of the present invention, the driving device 5 includes a motor 51 connected to one of the two lateral air deflectors 41, and a linkage mechanism 52 for linking the two lateral air deflectors 41, when the motor 51 is started to drive the lateral air deflector 41 connected thereto to rotate, under the linkage action of the linkage mechanism 52, the other lateral air deflector 41 rotates synchronously to synchronously adjust the angles of the two lateral air deflectors 41, so as to adjust the air outlet direction. If the high-cold-quantity demand area is located at the position close to the rear of the storage layer 2, the driving device 5 corresponding to the storage layer 2 is controlled to drive the transverse air deflectors 41 to rotate downwards and backwards until the air outlet ends formed by the two transverse air deflectors 41 in a surrounding mode are aligned with the high-cold-quantity demand area, and after the refrigeration system is started, cold air blown out of the air outlet can be blown to the high-cold-quantity demand area; when the high-cold-quantity demand area is located at the position, close to the front, of the storage layer 2, the driving device 5 corresponding to the storage layer 2 is controlled to drive the transverse air deflectors 41 to rotate forwards and upwards until the air outlet ends formed by the two transverse air deflectors 41 in an enclosing mode are aligned with the high-cold-quantity demand area, at the moment, the included angle between the transverse air deflectors 41 and the rear wall of the refrigeration chamber is close to 90 degrees, and after the refrigeration system is started, cold air blown out from the air outlet 3 can be blown forwards to the high-cold-quantity demand area to refrigerate quickly and effectively.
Specifically, one end of the transverse rotating shaft 412 in the transverse air guiding plate 41 connected to the motor 51 is connected to the motor 51, and the other end is engaged with the linkage 52.
In a specific embodiment, the linkage mechanism 52 includes two gears 521 respectively disposed at the end portions of the two lateral rotation shafts 412 on the same side, and a synchronous belt 522 engaged with the two gears 521, and the synchronous belt 522 can drive the two gears 521 to rotate synchronously, so that the two lateral air deflectors 41 rotate synchronously.
Fig. 5 shows a second embodiment of the present invention, which is different from the first embodiment in that: the driving device 5 ' includes two motors 51 ' connected to the two cross wind deflectors 41, respectively, and it is understood that the motors 51 ' are connected to the ends of the cross shafts 412 of the corresponding cross wind deflectors 41.
The two motors 51' are in communication connection with the control unit, so that the two transverse air deflectors 41 can be controlled to rotate respectively, the air outlet direction can be adjusted, the air supply area can be adjusted by adjusting the angle between the two transverse air deflectors 41, and it can be understood that the larger the angle between the two transverse air deflectors 41 is, the larger the air supply area is.
The second embodiment has the same structure as the first embodiment except for the above differences, and thus, the description thereof is omitted.
Further, the refrigerator further comprises a damper (not shown) for opening or closing the air outlet 3, and a driving motor for driving the damper to move, wherein the driving motor is in communication connection with the control unit. The control unit can control the driving motor according to the load information sensed by the sensing device so as to realize the opening and closing of the air outlet 3.
Specifically, when the control unit receives no load on a certain storage layer 2 fed back by the sensing device, the control unit controls the damper of the air outlet 3 corresponding to the storage layer 2 to move so as to close the air outlet 3.
In the embodiment that each group of air outlets comprises two air outlets 3 arranged at intervals in the left-right direction, when the load on the corresponding storage layer 2 fed back by the sensing device is concentrated on the right side, the control unit controls the air door on the right side corresponding to the storage layer 2 to move so as to open the air outlet 3 on the right side, and controls the air door on the left side to move so as to close the air outlet 3 on the left side, so that cold air is blown to the right side in a concentrated manner, and the refrigeration effect is enhanced; correspondingly, when the control unit receives the load on the storage layer 2 fed back by the corresponding sensing device and concentrates on the left side, the air door located on the left side corresponding to the storage layer 2 is controlled to move so as to open the air outlet 3 on the left side, and meanwhile, the air door located on the right side is controlled to move so as to close the air outlet 3 on the right side, so that cold air is blown to the left side in a concentrated mode, and the refrigeration effect is enhanced.
In the operation process of the refrigerator 100, the sensing device senses the load change on the corresponding storage layer 2 in real time and feeds the load change back to the control unit, so that when the control unit judges that a high-cooling-capacity demand area exists, the air deflector group 4 corresponding to the high-cooling-capacity demand area can be controlled to rotate in time, meanwhile, the corresponding air outlet 3 is controlled to be opened, and a refrigerating system is started to provide cooling capacity for the high-cooling-capacity demand area.
For example, in the operation process of the refrigerator, when the control unit obtains the load increase at a certain position according to the load information fed back by the sensing device, it is determined that a user puts a new article at the position, and it is determined that the position is a high-cooling-capacity demand region, the control unit controls the air guide plate group 4 corresponding to the storage layer 2 to rotate so that the air outlet end of the air guide plate group 4 is aligned with the high-cooling-capacity demand region, and controls the corresponding air outlet 3 to be opened, and meanwhile, the refrigeration system is started to rapidly cool the new article, so as to improve the fresh-keeping effect.
Further, the refrigerator 100 further includes a timing device (not shown) in communication connection with the control unit, after the control unit controls the driving device 5 and 5 'to rotate the air guide plate group 4 to a region where high cooling capacity is required and starts the refrigeration system, the timing device starts timing and feeds back the timing to the control unit after preset time, and the control unit controls the driving device 5 and 5' to drive the air guide plate group 4 to reset, so as to refrigerate the refrigeration compartment in a normal air supply manner, thereby enhancing uniformity of cooling capacity distribution in the refrigeration compartment.
It should be understood that the normal air blowing mode described above refers to an air blowing mode after the air guide plate group 4 is reset.
It can be understood that the preset time is not a fixed value, but is positively correlated with the load weight of the high-refrigeration-demand area, i.e. the larger the load weight of the high-refrigeration-demand area is, the longer the corresponding preset time is.
Further, referring to fig. 6, the present invention further provides a control method of the refrigerator, including the following steps:
s1, electrifying and starting;
s2: receiving load information on the storage layer;
in the embodiment where the sensing device includes a plurality of weight sensors uniformly distributed on the bottom of the storage layer, the load information in step S2 includes the load weight and the load position. Of course, this is not a limitation.
S3: and adjusting the air outlet direction of the air outlet corresponding to the storage layer according to the load information.
In an embodiment where the sensing device includes a plurality of weight sensors uniformly distributed at the bottom of the storage layer, the step S3 of adjusting the air outlet direction of the air outlet corresponding to the storage layer according to the load information specifically includes the following steps:
s31: obtaining a high-cooling-capacity demand area according to the load information;
specifically, the control unit receives load weight information fed back by the gravity sensors corresponding to each layer of the storage layer 2, compares the load weight information of the layer, and determines that the position of the gravity sensor corresponding to the highest load weight is the high-refrigeration-capacity demand area.
S32: and adjusting the air guide plate group corresponding to the storage layer to enable the air outlet direction to face the high-cooling-capacity demand area.
Specifically, the control unit controls the driving devices 5 and 5' corresponding to the storage layer 2 to drive the corresponding wind deflector sets 4 to rotate, so that the air outlet ends of the wind deflector sets 4 are aligned with the high-cooling-capacity demand areas, and therefore, after the corresponding air outlets 3 are in an open state and the refrigeration system is started, cold air blown out from the air outlets 3 is guided to blow towards the high-cooling-capacity demand areas through the wind deflector sets 4, and the high-cooling-capacity demand areas are refrigerated rapidly and effectively in a targeted manner.
Further, after the step S2, the step S3 is preceded by the steps of:
judging whether the storage layer is loaded or not according to the load information, and if not, controlling the air outlet corresponding to the storage layer to be closed; if yes, the process goes to step S3.
It can be understood that if there is a load on the storage layer, the corresponding air outlet may be controlled to be opened before the step S3 is skipped, or the corresponding air outlet may be controlled to be opened after the step S3 is completed.
Further, after step S3, the control method further includes the steps of:
s4: and after the preset time, controlling the air guide plate group to reset.
Specifically, the control unit obtains the preset time according to the load weight information of the high-cooling-capacity demand area, and controls the driving devices 5 and 5' to drive the air guide plate group 4 to reset after blowing air to the high-cooling-capacity demand area for the preset time, so as to start a normal air supply mode and provide cooling capacity for the refrigeration chamber.
It can be understood that the preset time is not a fixed value, but is positively correlated with the load weight of the high-refrigeration-demand area, i.e. the larger the load weight of the high-refrigeration-demand area is, the longer the corresponding preset time is.
Further, after the step S4, the above steps S2-S4 are repeated, that is, in the operation process of the refrigerator 100, the sensing device senses load information on the corresponding storage layer in real time and feeds the load information back to the control unit, so that when the load on the storage layer changes, if a user puts a new load into the refrigeration compartment, it is determined that an area corresponding to the new load is a high-cooling-capacity demand area, the corresponding air guide plate group 4 is adjusted, and the refrigeration system is controlled to be started to intensively refrigerate the high-cooling-capacity demand area for a preset time, so that a quick cooling effect is achieved, and the fresh-keeping effect of the refrigerator 100 is enhanced.
In summary, in the refrigerator 100 of the present invention, the sensing device is disposed on the storage layer 2, the air guide plate group 4 for adjusting the air outlet direction is disposed at the air outlet 3, and the control unit can adjust the air outlet direction according to the load information on the storage layer 2 sensed by the sensing device, that is, the control unit obtains the high-cooling-capacity demand region on the storage layer 2 according to the received load information, and then controls the air guide plate group 4 corresponding to the storage layer 2 to rotate, so that the air guide plate group 4 protrudes from the air outlet 3 to the high-cooling-capacity demand region, and thus the cold air blown from the air outlet 3 can be blown to the high-cooling-capacity demand region, and the high-cooling-capacity demand region can be rapidly and effectively refrigerated in a targeted manner.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
