Fig. 1 is a schematic structural view of a liner compartment in a refrigerator according to an embodiment of the present invention, as shown in fig. 1, and referring to fig. 2 to 8, and the embodiment of the present invention provides a drawer assembly including a drawer 2, a slide 3, a first actuating member 41, and a second actuating member 42. Hollow slide rails 21 extending forward and backward are formed on the outer surfaces of the left and right side walls of the drawer 2, respectively. The slideway 3 and the hollow slide rail 21 are oppositely arranged in a one-to-one correspondence manner, a sliding groove 31 which is in plug bush fit with the hollow slide rail 21 is formed on the outer surface of one side of the slideway 3, and a cavity 33 is formed on the other side of the slideway. The first actuating member 41 is installed in the hollow cavity of the hollow slide rail 21, the second actuating member 42 is installed in the cavity 33 of the slide rail 3, the first actuating member 41 and the second actuating member 42 are magnetic components capable of achieving mutual magnetic attraction and/or magnetic repulsion, that is, when one of the first actuating member 41 and the second actuating member 42 is a magnet, the other is a magnet or a magnetic component, the magnet comprises a permanent magnet and an electromagnet, the magnetic component refers to a strong magnetic substance attracted by the magnet under a magnetic environment, such as a ferromagnetic material, and the like, and specifically when the first actuating member 41 is a permanent magnet, the second actuating member 42 can be an electromagnet, a permanent magnet or a ferrous component; when the first actuator 41 is an electromagnet, the second actuator 42 may be an electromagnet, a permanent magnet, or an iron member; when the first actuator 41 is a ferrous member, the second actuator 42 may be an electromagnet or a permanent magnet.

Thus, when the drawer 2 enters the slideway 3, the first actuating component 41 and the second actuating component 42 are influenced by the magnetic force, so that the hollow sliding rail 21 has an upward acting force, and when the acting force is smaller than the total weight of the drawer 2 and the articles in the drawer 2, the magnetic force shares part of the total weight, so that the friction force between the hollow sliding rail 21 and the slideway 3 is reduced, and the service life of the hollow sliding rail 21 is prolonged; when the magnetic force acting between the first actuator 41 and the second actuator 42 is greater than the total weight of the drawer 2 and the articles in the drawer 2, the hollow slide rail 21 drives the drawer 2 to float, so as to achieve a "magnetic suspension" effect, thereby avoiding friction between the hollow slide rail 21 and the slide way 3, and further prolonging the service life of the hollow slide rail 21.

In some embodiments of the present invention, when the first actuating member 41 and the second actuating member 42 are permanent magnets, the permanent magnets are elongated and extend back and forth, the length of the second actuating member 42 is equal to the length of the slide rail 3, and the length of the first actuating member 41 is equal to the length of the hollow slide rail. When the first actuator 41 is positioned above the second actuator 42, the polarities of the first actuator 41 and the second actuator 42 are opposite to each other in the vertical direction, and they are magnetically repulsive. Or, when the first actuating member 41 is located below the second actuating member 42, the two are magnetically engaged. Whether the magnetic repulsion fit or the magnetic attraction fit provides an upward effect for the hollow slide rail 21 to reduce or avoid friction between the hollow slide rail 21 and the slideway 3.

In some embodiments of the present invention, the first actuating member 41 is a permanent magnet, and the first actuating member 41 is a strip and extends back and forth. The second actuator 42 is a columnar electromagnet extending vertically, and two or more second actuators 42 are arranged at intervals in the front-rear direction. The second actuating member 42 is located below the slide slot 31. The length of the first actuator 41 in the cavity may be equal to the length of the second actuator 42 corresponding thereto, and the initial position and the final position of extension of both the first actuator 41 and the second actuator 42 are the same; it is also possible to set the length of the first actuator 41 to be greater than the length of the arrangement of the second actuator 42; or the first actuator 41 extends for a length equal to the length of the hollow slide rail 21. One end of the first actuator 41 extends from the rear end of the cavity to the front end of the cavity. The second actuator 42 may be arranged from one end of the slideway 3 to the other. At this time, when the drawer is pulled out or pushed in, the second actuating component 42 provides an upward acting force to the hollow slide rail 21 within the length range of the slide way 3 as much as possible, so as to reduce the friction force between the hollow slide rail 21 and the slide way 3, and realize that the drawer is used by people with labor saving.

In this embodiment, the second actuator 42 is an electromagnet, the first actuator 41 is a permanent magnet, and the second actuator 42 is located below the slide groove 31. After the electromagnet is energized, the polarity of the upper end of the electromagnet is the same as the polarity of the lower side of the permanent magnet, the permanent magnet and the electromagnet cooperate with each other in a magnetic repulsion manner, and the magnetic repulsion cooperation of the first actuating member 41 and the second actuating member 42 provides an upward acting force to the hollow slide rail 21. When the current drawn by the electromagnet increases such that the magnetic force of the repulsive magnetic interaction exceeds the total weight of the drawer 2 and the contents of the drawer 2, the drawer 2 becomes airborne relative to the slide 3.

In some embodiments of the present invention, the first actuating member 41 is a permanent magnet, and the first actuating member 41 is a strip and extends back and forth. The first actuator 41 extends up to the length of the hollow slide rail 21. The second actuator 42 is a columnar electromagnet extending vertically, and two or more second actuators 42 are arranged at intervals in the front-rear direction. The second actuating member 42 is located above the slide slot 31.

In this embodiment, the second actuating member 42 is an electromagnet, the first actuating member 41 is a permanent magnet, and the second actuating member 42 is located above the sliding slot 31, so that the polarities of the lower side of the electromagnet and the upper side of the permanent magnet are opposite, and the first actuating member 41 and the second actuating member 42 are magnetically engaged, and when the magnetic force of the magnetic engagement of the first actuating member 41 and the second actuating member 42 is greater than the total weight of the drawer 2 and the objects in the drawer 2, the drawer 2 floats relative to the sliding track 3, thereby reducing or even avoiding the friction force between the drawer 2 and the sliding track 3.

In some embodiments of the present invention, the first actuating member 41 and the second actuating member 42 are electromagnets. When the first actuator 41 is located above the second actuator 42, the polarities of the upper and lower opposite sides of the two electromagnets are the same, so that the first actuator 41 and the second actuator 42 are in magnetic repulsion engagement with each other. When the first actuating member 41 is located below the second actuating member 42, the polarities of the two electromagnets on the opposite sides are opposite, so that the first actuating member 41 and the second actuating member 42 are magnetically engaged with each other. The magnetic attraction fit or the magnetic repulsion fit enables the hollow slide rail 21 to obtain an upward acting force so as to share or completely bear the total weight of the drawer 2 and the articles in the drawer 2, thereby achieving the effect of reducing the friction force between the hollow slide rail 21 and the slide rail 3.

In some embodiments of the present invention, when the second actuator 42 is an electromagnet or a permanent magnet, the first actuator 41 is a magnetic member, such as: and (4) iron products. At this time, the second actuator 42 can only be located above the first actuator 41. This arrangement utilizes the principle of attraction of the magnet of the second actuator 42 to the magnetic member of the first actuator 41, so that the hollow slide rail 21 corresponding to the first actuator 41 obtains an upward force.

Specifically, when the cavity 33 is disposed above the sliding slot 31, the first actuating member 41 and the second actuating member 42 are magnetically engaged; when the cavity 33 is disposed below the chute 31, the first actuating member 41 and the second actuating member 42 are in a magnetic repulsion engagement. The distance between the upper and lower side walls of the slide groove 31 is greater than the distance between the upper and lower side walls of the hollow slide rail 21 to realize the up-and-down movement of the hollow slide rail 21. In this case, the first actuator 41 is a permanent magnet, the second actuator 42 is an electromagnet, and the polarities of the opposite sides of the two are the same, so as to provide an upward force to the hollow slide rail 21.
