Referring to fig. 2 to 8, the storage unit 900 may be disposed in the storage chamber 1100 in a manner of being pulled out or pushed back, and in particular, the storage unit 900 may include a drawer 100, where the drawer 100 defines at least one storage space 101 and has an opening 102 that is opened upwards, and a user may take a storage placed in the storage space 101 from the opening 102, or the user may place the storage in the storage space 101 from the opening 102, and the drawer 100 may be disposed in the storage chamber 1100 in a manner of being pushed back and forth along the depth direction of the storage chamber.

Referring to fig. 3, the drawer 100 may be composed of a drawer body 104 and a front panel 103. To facilitate different modeling of the drawer to accommodate different platform products.

The storage unit 900 includes a cover 200, the cover 200 being supported within the storage chamber 1100 for hermetically closing the opening 102 from a separated position separated from the opening 102 to a closed position when the drawer 100 is pushed back into the storage chamber 1100.

The storage chamber 1100 is constructed with a pair of opposite supporting bodies 500 therein, and the cover 200 is supported above the opening 102 of the drawer 100 by the first and second supporting shafts 201 and 202 being engaged with the supporting bodies 500.

Alternatively, the storage chambers 1100 may be provided with guide rails 600 in pairs, the drawer 100 is provided with guide rail ribs 105, the drawer 100 is mounted on the guide rails 600 through the guide rail ribs 105, and the guide rails 600 guide the drawer 100 to be slidably disposed in the storage chambers 1100.

The refrigerator 1000 includes a switch assembly for determining whether the storage unit 900 is in a closed state.

The switch assembly is provided with a predetermined determination range, and when the detection value or the correlation value of the detection value falls within the predetermined determination range, it is determined that the storage unit 900 is in the off state.

The refrigerator 1000 includes a biasing mechanism 511, the biasing mechanism 511 being disposed within the storage compartment 1100 and adapted to bias the storage unit 900 such that the storage unit 900 moves beyond the determination range of the switch assembly when not in the closed state.

The force application mechanism 511 moves the storage unit 900 which is not in the closed state beyond the judging range of the switch assembly to monitor the closed state of the storage unit 900, so that the situation that misjudgment occurs when the storage unit 900 is not in the closed position is effectively avoided, and compared with the smell or pressure sensor, the switch assembly is more beneficial to configuration, and the switch assembly does not need to be arranged inside the storage unit.

The urging mechanism 511 may apply a force to the drawer 100 or may apply a force to the lid 200 to move the lid 200 or the drawer 100 in a direction away from the position where the closed state is located.

In one embodiment of the present application, the force applying mechanism 511 applies force to the cover 200, and the cover 200 drives the drawer 100 to move away from the closed position.

In one or more embodiments of the application, the switch assembly includes a magnetic device 150 and a magnetic detection device 1130, the magnetic device 150 configured to generate a magnetic signal; the magnetic sensing device 1130 is configured to sense magnetic signal strength. The high sensitivity and response speed of the magnetic switch are more beneficial to the refrigeration appliance with the force application mechanism to reduce the possibility of misjudgment.

In one or more embodiments of the application, the storage unit 900 exists as a sealed storage unit that is capable of providing a low pressure or special gas storage environment for a refrigeration appliance by configuring the functional unit 800.

When the storage unit 900 includes the functional unit 800, the position of the storage unit 900 in the closed state falls within the switch assembly determination range as one of conditions for triggering the operation of the functional unit 800.

Specifically, the functional unit 800 may be a pumping assembly, which is disposed on the cover 200 to provide a low-pressure storage environment of the storage space 101, and the switching assembly determines whether the storage unit 900 providing the low-pressure storage environment is in a closed state.

Referring to fig. 3, the refrigerator may include a locking mechanism 400, and the locking mechanism 400 locks the storage unit 900 in the storage compartment 1100 to maintain a closed state so as to fall within the determination range of the switch assembly.

The magnetic induction device typically has a set magnetic threshold range within which it may be turned on due to the sensed magnetic signal strength being sufficiently large that it is a range, rather than a single value, that it is possible to turn on.

However, in the embodiment of the present application, in order to more accurately determine whether the storage unit 900 is closed, the determination range is defined as a minimum value where the magnetic signal strength detected by the magnetic detection device 1130 is greater than the preset magnetic threshold range, or a distance value corresponding to a minimum value where the vertical distance between the magnetic detection device 1130 and the magnetic device 150 is smaller than the preset magnetic threshold range. Thus, when the storage unit 900 is not in the closed state, the detecting device 1130 is not turned on due to the force applying mechanism 511.

When the storage unit 900 is in the closed state, the magnetic signal strength detected by the magnetic detection device 1130 is greater than the maximum value of the preset magnetic threshold range, or the vertical distance between the magnetic detection device 1130 and the magnetic device is smaller than the distance value corresponding to the maximum value of the preset magnetic threshold range. The closed position serves as a position to determine the ability to turn on the switch assembly.

This can advantageously reduce the possibility of erroneous judgment due to conduction in the magnetic threshold range.

As can be seen in conjunction with fig. 1-6, when drawer 100 is pushed back into storage compartment 1100, the force applied by force applying mechanism 511 is overcome such that the distance between magnetic device 150 and magnetic sensing device 1130 is gradually reduced.

Specifically, the urging mechanism 511 includes a spring 513, one end of the spring 513 is connected to the storage unit 900, and the other end is fixed with respect to the compartment side wall 1100a of the storage compartment 1100.

The force applying mechanism 511 may be disposed at the rear end of the cover 200, may be disposed in the support 500, or may be disposed between the support 500 and the cover 200, and may provide a pulling force or a pushing force to the cover.

When the locking mechanism 400 is unlocked, the force applying mechanism 511 is adapted to drive the cover 200 in a direction away from the closed position, and the drawer 100 is driven by the cover 200 such that the magnetic device 150 is away from the magnetic sensing device 1130 beyond the determination of the switch assembly.

One of the magnetic device 150 and the magnetic sensing device 1130 is fixed to the storage unit 900, and the other is fixed to the storage compartment 1100. The distance between the two can be changed to realize detection judgment of the switch assembly. In embodiments of the present application, it is preferred that the magnetic sensing device 1130 is secured within the storage compartment to facilitate power to the cable and magnetic sensing device 1130.

When the spring 513 is preferably an extension spring, the force applied by the force applying mechanism 511 is overcome to gradually decrease the distance between the magnetic device 150 and the magnetic sensing device 1130 when the drawer 100 is pushed back into the storage compartment 1100.

When the locking mechanism 400 is unlocked, the force applying mechanism 511 is adapted to drive the cover 200 in a direction away from the closed position, and the drawer 100 is driven by the cover 200 such that the magnetic device 150 is away from the magnetic sensing device 1130 beyond the determination of the switch assembly.

It will be appreciated that in the present utility model, one of the first engagement portion 401 or the second engagement portion 402 is a movable member, and the other is a fixed member to cooperatively perform a locking function. Thus, the movable member is driven to lock with the fixed member in the process that the storage unit is pushed back to the locked state.

The cover 200 is supported in the storage chamber 1100 by the support 500, and moves from a position separated from the opening 102 of the drawer 100 to a closed position to seal-close the opening to fall within a determination range of the switch assembly when the drawer 100 is pushed back into the storage chamber.
