Of course, in other embodiments, the drawer outer barrel 2 can be used for storage structures on other refrigeration equipment or other devices.

In this embodiment, the supporting member 3 is a protruding rib formed by protruding from the left and right sides of the inner container 1 along the transverse direction, and the protruding rib and the inner container 1 are integrally formed, so that the upper side of the protruding rib is relatively flat. In other embodiments, the protruding rib may protrude in the front-back direction, or the supporting member 3 may be assembled on the inner container 1.

In this embodiment, the supporting mechanism is disposed between the bottom of the inner container 1 and the drawer outer barrel 2, but in other embodiments, the supporting mechanism may also be disposed between the side wall of the inner container 1 and the side wall of the drawer outer barrel 2.

As shown in fig. 1 and 2, a first embodiment of the refrigerator according to the present invention is provided, in this embodiment, the drawer outer 2 has a receiving cavity 21 opened along a vertical direction, and a receiving groove 22 located at a side of the receiving cavity 21 to receive the drawer. The outer drawer barrel 2 further has an overlapping part 23 protruding outwards and overlapping the protruding rib, so that the outer drawer barrel 2 is convenient to mount.

The supporting mechanism comprises a supporting column 4 matched with the bottom of the inner container 1 and the outer drawer barrel 2 and an electromagnetic assembly arranged between the supporting column 4 and the outer drawer barrel 2 and/or between the supporting column 4 and the bottom of the inner container 1, and after the electromagnetic assembly is electrified, the supporting column 4 moves downwards to abut against the bottom of the inner container 1 to provide supporting force for the outer drawer barrel 2.

The refrigerator also comprises a weight sensor for monitoring the weight of the outer drawer barrel 2 and a sensor arranged between the lap joint part 23 and the convex rib for detecting and acquiring the starting signal of the electromagnetic assembly, namely the outer drawer barrel 2 is arranged on the convex rib and then can acquire the starting signal of the electromagnetic assembly. And whether in order to obtain support column 4 and inner bag 1 bottom butt in time, can be through set up distance sensor on support column 4 or inner bag 1 bottom in order to detect the distance between support column 4 and the inner bag 1 bottom, when the distance is zero, then show mutual butt or set up force cell sensor in the foaming layer of inner bag bottom, when force cell sensor appears the reading, then show the butt, also can pass through electric current judgement, for example, when adopting rated current control support column 4 to remove, when support column 4 butt inner bag 1 bottom, the electric current can change suddenly, also can judge.

Specifically, in the present embodiment, the supporting pillar 4 is disposed in the accommodating cavity 21, and in order to save cost, the electromagnetic component may be disposed between the supporting pillar 4 and the outer barrel 2 of the drawer or between the supporting pillar 4 and the bottom of the inner container 1.

The electromagnetic assembly includes a magnetic element 5, an inductive element 6, and a power switch (not shown) electrically connected to the inductive element 6. In this embodiment, the magnetic element 5 is a magnet, and the inductive element 6 is a solenoid or an electromagnet. Thus, only one inductive element 6 is provided, and only one set of circuit is needed, so as to simplify the design and reduce the cost, but in other embodiments, the electromagnetic element may include two sets of inductive elements 6, and then the generation of the attraction force or the repulsion force is controlled respectively.

When the electromagnetic assembly is disposed between the supporting pillar 4 and the outer drawer barrel 2, the magnetic element 5 is disposed on one of the top end of the supporting pillar 4 and the outer drawer barrel 2, the inductive element 6 is disposed on the other, and the power switch is disposed on the inner container 1. In this embodiment, the inductance element 6 is disposed in the accommodating cavity 21, and the magnetic element 5 is disposed at the top end of the supporting pillar 4, so that a circuit matched with the inductance element 6 is conveniently disposed on the drawer outer barrel 2.

For the sake of simple structure, the inductance element 6 may have a mating connector (not shown) protruding from the lower surface of the overlapping portion 23, and the upper surface of the rib is provided with a mating connector (not shown) that is mated with the mating connector, and the mating connector may be connected to a power source through a wire harness in the inner container 1. Therefore, the structure is simple, and the outer barrel 2 of the drawer is convenient to disassemble and assemble.

When the electromagnetic component is arranged between the support column 4 and the bottom of the inner container 1, the magnetic element 5 is arranged on one of the bottom end of the support column 4 and the bottom of the inner container 1, the inductance element 6 is arranged on the other, and the power switch is arranged on the inner container 1. In this embodiment, the inductance element 6 is disposed on the bottom of the inner container 1, and the magnetic element 5 is disposed at the bottom end of the supporting pillar 4, so that a circuit matched with the inductance element 6 can be conveniently disposed on the inner container 1, and the butting connector and the matching connector are not required to be disposed.

In order to ensure that the supporting column 4 can be fixed in the accommodating cavity 21, the supporting mechanism further has a matching structure for fixing the supporting column 4 in the accommodating cavity 21. In this embodiment, the matching structure is a magnetic metal (not shown) that can be absorbed by the magnetic element 5, when the drawer outer barrel 2 is mounted on the protruding rib, the supporting column 4 can also be fixed in the accommodating cavity 21, and then the repulsion force is generated between the inductance element 6 and the magnetic element 5 by controlling the power switch, so that the supporting column 4 moves downward and abuts against the bottom of the inner container 1 to support the drawer outer barrel 2, thereby not only improving the load of the drawer outer barrel 2, but also reducing the risk of damage to the protruding rib.

The electromagnetic assembly can work through a built-in control logic, for example, when the support columns 4 move downwards to abut against the bottom of the inner container 1, the movement is stopped, so that each support column 4 can adapt to the uneven condition of the bottom of the inner container 1, and the condition that the inner container 1 is damaged due to continuous movement is avoided. It is of course also possible to provide the power switch individually for each support column 4.

Through setting up accept chamber 21 and support column 4, on the one hand, can guarantee that support column 4 moves down smoothly, is difficult for appearing the skew of other directions except direction of height, and on the other hand sets up electromagnetic component between support column 4 and the outer bucket 2 of drawer, owing to accept chamber 21 spacing to support column 4 for support column 4 only can move in direction of height, thereby has guaranteed the stability of electromagnetic force, makes the direction of electromagnetic force be the direction of height as far as possible promptly. But also can reduce the size of the electromagnetic component and reduce the production cost.

In order to close the power switch when the support pillar 4 moves downwards to abut against the bottom of the inner container 1, the refrigerator can be further provided with a fixing structure for fixing the support pillar and the outer drawer barrel 2, so that when the support pillar 4 moves downwards to abut against the bottom of the inner container 1, electromagnetic force is not needed.

As shown in fig. 3 to 5, a second embodiment of the refrigerator according to the present invention is different from the first embodiment in that the drawer outer 2 further has a mounting cavity 24 formed by being recessed outward from the receiving cavity 21, the mounting cavity 24 is located at one or both of the left and right sides of the receiving cavity 21, and in other embodiments, the mounting cavity 24 may be located at other positions, such as the front and rear sides, of the receiving cavity 21.

In this embodiment, the matching structure includes a fixing member 7 pivotally connected to the inner wall of the mounting cavity 24, and a reset structure 8 matching with the fixing member 7, the supporting pillar 4 has a plurality of positioning structures 41 arranged along the up-down direction, when one of the drawer outer tub 2 and the supporting pillar 4 moves along the up-down direction relative to the other one, the supporting pillar 4 is usually moved downwards, the fixing member 7 moves towards the direction away from the supporting pillar 4, and when the fixing member 7 corresponds to the positioning structures 41, the fixing member 7 is reset under the action of the reset structure 8 and fixed with the positioning structures 41.

Therefore, the supporting column 4 can be fixed in the accommodating cavity 21 through the above structure, the positioning structure 41 is a clamping groove which is obliquely and upwards formed, the fixing member 7 is a clamping jaw which is matched with the clamping groove, and the resetting structure 8 is arranged on the elastic member between the fixing member 7 and the inner wall of the mounting cavity 24, so that the supporting column 4 can be conveniently and smoothly moved downwards through the above structure.

Of course, in other embodiments, the positions of the positioning structure 41 and the mating structure may be interchanged, that is, the positioning structure 41 is disposed in the receiving cavity 21, and the mating structure is disposed on the supporting pillar 4, so that the installation cavity 24 may not be required. The reset structure 8 may also be a torsion spring, or an elastic sheet that is integrally formed with the fixing member 7 and abuts against the inner wall of the mounting cavity 24.

In order to further reduce the energy consumption, the upper inner wall of the mounting cavity 24 further has a stopping portion 25 for stopping the fixing element 7 from rotating upward, in this embodiment, the stopping portion 25 is the upper inner wall of the mounting cavity 24, but in other embodiments, the stopping portion 25 may also be a structure protruding from the upper inner wall of the mounting cavity 24.

Through the arrangement of the stop part 25 and the matching of the positioning structure 41, when the support pillar 4 is fixed with the fixing part 7, no action force is required to be generated between the inductance element 6 and the magnetic element 5 (the electromagnetic assembly is repulsive force when positioned between the support pillar 4 and the drawer outer barrel 2, and the electromagnetic assembly is attractive force when positioned between the support pillar 4 and the bottom of the inner container 1), that is, the inductance element 6 is not required to be powered on, therefore, when the support pillar 4 moves down and abuts against the bottom of the inner container 1, power can be cut off, and the support is realized by means of a mechanical structure, so that the energy consumption is greatly reduced. Of course, in other embodiments, the support post 4 may be manually moved downward.

In this embodiment, the accommodating cavity 21 penetrates through the outer barrel 2 of the drawer in the up-down direction, so that when the supporting pillar 4 is installed, the accommodating cavity 21 is installed from top to bottom, which is very convenient. The refrigerator further includes a sealing member 9 at the top of the receiving chamber 21, thereby increasing sealability and beauty.

When the electromagnetic assembly is disposed between the supporting pillar 4 and the drawer outer 2, in order to facilitate the supporting pillar 4 to be installed in the receiving cavity 21, the inductance element 6 may be disposed at the lower end of the sealing member 9, the inductance element 6 has a mating connector (not shown) protruding from the sealing member 9, and the drawer outer 2 has a mating connector (not shown) that is mated with the mating connector, and the mating connector may be connected to a power source through a wire harness. Therefore, the supporting column 4 can move downwards normally, the centers of the inductive element 6 and the magnetic element 5 are closer to the same straight line, and stronger electromagnetic force can be provided under the same current, namely, the energy consumption can be reduced as much as possible under the condition of meeting the requirement of the electromagnetic force.

The invention also provides a method for controlling the support of the outer barrel of the drawer in the refrigerator, which comprises the following steps:

acquiring an electromagnetic assembly starting signal;

when receiving the electromagnetic assembly starting signal, turn on switch, provide certain electric current for inductance element 6 to make inductance element 6 produce the same magnetism with magnetic element 5, make support column 4 move down until butt inner bag 1 bottom.

The above-mentioned "constant current is supplied to the inductance element 6" condition further includes: acquiring the gravity information of the drawer outer barrel 2, and turning on the power switch when the gravity of the drawer outer barrel 2 is greater than a preset value. Thus, when the drawer outer barrel 2 is light, it is not necessary to provide an additional supporting force thereto, thereby reducing power consumption.

When the support column 4 abuts against the bottom of the inner container, the gravity information of the drawer outer barrel 2 is continuously acquired, and the current supplied to the inductance element 6 is adjusted according to the gravity information of the drawer outer barrel 2, so as to adjust and control the magnetic force between the inductance element and the magnetic element. Therefore, the current can be adjusted according to the weight of the outer barrel 2 of the drawer to provide proper supporting force, the convex ribs are not easy to damage, and unnecessary energy consumption waste can be avoided.

For the second embodiment, the support control method further includes: when the support column 4 abuts against the bottom of the inner container 1, the power switch is turned off. This is because it is possible to fix the drawer outer 2 to provide a supporting force.

When the electromagnetic assembly is arranged between the support column 4 and the bottom of the inner container 1, the support control method of the outer barrel of the drawer in the refrigerator comprises the following steps:

and acquiring an electromagnetic assembly starting signal, wherein the inductance element 6 generates magnetism opposite to that of the magnetic element 5, and the support column 4 moves downwards until abutting against the bottom of the liner 1.

And acquiring an electromagnetic assembly starting signal and gravity information of the drawer outer barrel 2, and when the gravity of the drawer outer barrel 2 is greater than a preset value, turning on a power switch to enable the inductance element 6 to generate magnetism.

In summary, the refrigerator of the invention is provided with the supporting member 3 supporting the outer drawer barrel 2 on the inner container 1, and the supporting mechanism matching with the inner container 1 to support the outer drawer barrel 2. Thereby can increase and add the holding power, not only can increase the load of drawer outer bucket 2, can also reduce the impaired risk of inner bag 1.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
