Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
For convenience in explanation, the description herein uses terms indicating relative spatial positions, such as "upper," "lower," "inner," "outer," and the like, to describe one element or feature's relationship to another element or feature as illustrated in the figures. The term spatially relative position may encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "above" other elements or features would then be oriented "below" or "above" the other elements or features. Thus, the exemplary term "below" can encompass both a spatial orientation of below and above.
The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. As in the present invention, for convenience of description, in a normal use of the refrigerator, a direction toward the ground is downward and a direction away from the ground is upward; the direction parallel to the ground is a horizontal direction, and the direction vertical to the ground is a vertical direction; the side close to the user is the front side, and the side far away from the user is the back side.
As shown in fig. 1, an embodiment of the present invention provides a method for controlling anti-toppling of a refrigerator, the method including the following steps, and the method is described as follows:
s10: when the fact that the actual load weight of a drawer or a door body 1 of the refrigerator exceeds the preset load weight and the number of the opened drawers and door bodies 1 of the refrigerator exceeds a preset number is detected, the refrigerator is judged to topple;
as shown in fig. 2 to 4, when the storage space of the refrigerator, such as the drawer or the door 1, is filled with articles and is overweight, the drawer or the door 1 of the refrigerator is opened, and the gravity center of the refrigerator is easy to incline or topple after moving forward. The detection unit is arranged in the refrigerator and used for detecting the actual load condition of the drawer or the door body 1 of the refrigerator, and when the actual load weight exceeds the preset load weight and the number of the opened drawer and the door body 1 of the refrigerator exceeds a preset number, the gravity center of the refrigerator moves forwards, namely the refrigerator is about to topple or topples over.
Optionally, under the overweight condition, when the number of the opened drawers and the door body 1 of the refrigerator exceeds a preset number, it is determined that the refrigerator has fallen, and at this time, the opened drawers and the door body 1 of the refrigerator may be overweight or normally loaded, but both of the two conditions may cause the refrigerator to fall.
Optionally, the preset number may be an assumed number set in advance, or may be a number set in due time according to an actual load condition of the refrigerator drawer or the door body 1.
S20: and controlling the lower drawer push rod 3 to extend to push and open the lower drawer 2 of the refrigerator, and stopping the lower drawer push rod 3 at a specified position to resist the closing of the lower drawer 2.
As shown in fig. 5 to 6, a control unit is further disposed inside the refrigerator, and after the detection unit detects and determines that the refrigerator is toppled, the control unit first controls the lower drawer push rod 3 inside the refrigerator, and extends the lower drawer push rod 3, so that the lower drawer push rod 3 pushes the lower drawer 2 of the refrigerator and opens the lower drawer 2; after the lower drawer push rod 3 extends for a certain distance, the lower drawer push rod 3 is stopped at a designated position and fixed, so that the lower drawer push rod 3 is propped against the lower drawer 2 to keep the lower drawer 2 in an open state all the time. Thus, the front end of the lower drawer 2 can be finally abutted against the ground 10 in the process of falling of the refrigerator, and simultaneously, the front end of the lower drawer and the two front supporting legs 5 of the refrigerator jointly act to support the refrigerator and resist the further falling of the refrigerator, and finally the function of preventing the refrigerator from falling down is achieved.
