In other embodiments, the included angle α formed by the working grooves 131 (including the first working groove 131 and the second working groove) with respect to the direction from front to back may be an obtuse angle. In this case, the boss 124 of the cover 120 is located on the front side of the cam 152 in the operating state.

In some embodiments, the obtuse angle included by the included angle α can be between 135 degrees and 145 degrees.

With continued reference to fig. 6, in a specific implementation, the motor assembly 150 further includes a connector 153 and a motor cover 154.

Specifically, one end (e.g., an upper end) of the link 153 is drivingly connected to an output shaft of the motor 151, and the other end (e.g., a lower end) thereof is drivingly connected to the cam 152, so that the cam 152 is driven by the motor 151 to generate a first rotation or a second rotation.

The motor cover 154 is adapted to support the connection 153, and the motor 151 drivingly connected to the connection 153. Also, the motor cover 154 is further provided with a motor cover hole 154a through which the other end (e.g., lower end) of the connecting member 153 passes, and the other end (e.g., lower end) of the connecting member 154 is connected to the cam 152 through the motor cover hole 154 a.

In a specific implementation, one end (e.g., an upper end) of the connection member 153 has a larger size than the other end (e.g., a lower end) thereof, so that the one end (e.g., the upper end) cannot pass through the motor cover hole 154a to be located above the motor cover 154.

In a specific implementation, the motor assembly 150 is adapted to be mounted to the interior top wall 101 of the refrigerated compartment 100 by a motor cover 154, see fig. 2.

Specifically, the inner top wall 101 of the refrigerating compartment 100 has an inwardly recessed groove (not shown) at a portion thereof adjacent to the motor assembly 150 to receive the motor 151 of the motor assembly 150 and a portion of the connection member 153 above the motor cover 154.

In a specific implementation, the motor cover 154 may be mounted to the inner top wall 101 of the refrigerated compartment 100 by fasteners.

Specifically, the motor cover 154 is further provided with third mounting holes 154b such that fasteners pass through the third mounting holes 154b to mount the motor cover 154 to the inner top wall 101 of the refrigerating compartment 100.

In this way, the portion of the motor 151 and the connecting member 153 above the motor cover 154 can be hidden in the recess of the inner top wall 101 of the refrigerating compartment 100, see fig. 2. Not only is the appearance of the refrigeration compartment 100 attractive, but also the space occupied by the motor assembly 150 in the refrigeration compartment 100 is reduced, thereby saving cost.

In the present embodiment, the motor 151 is adapted to drive the cam 152 via the connection 153 to generate a first rotation or a second rotation opposite to the first rotation.

In the example shown in fig. 3-7, as the cam 152 makes the first rotation, the distal end 152a of the cam 152 is adapted to progressively approach the boss 124 of the lid 120 from front to rear such that the cam 152 pushes the boss 124 to make a self-forward-to-rear movement.

Since the moving

members

125, 126 are adapted to move along the working groove 131 in the working state (non-attached and detached state), and the working groove 131 forms an acute angle with respect to the direction from the front to the rear. Therefore, when the cam 152 pushes the boss 124 to move from front to back, the moving

pieces

125, 126 are adapted to move diagonally upward from front to back along the working groove 131, thereby bringing the cover 120 to move diagonally upward from front to back to raise the cover 120.

In some embodiments, when the distal end 152a of the cam 152 is rotated into abutment with the boss 124 of the lid 120, the lid 120 is raised to the uppermost position.

In the example shown in fig. 3 to 7, when the cam 152 makes the second rotation, the distal end 152a of the cam 152 gradually moves away from the boss 124 of the cover 120. In this situation, the boss 124 of the lid 120 is no longer pushed by the cam 152 from the front to the rear, and the lid 120 tends to move downward under its own weight.

Since the moving

members

125, 126 are adapted to move along the working groove 131 in the working state (non-attached and detached state), and the angle α formed by the working groove 131 with respect to the direction from the front to the rear is acute. Therefore, when the cover 120 tends to move downward, the moving

members

125, 126 are adapted to move obliquely downward from back to front along the working groove 131, thereby bringing the cover 120 to move obliquely downward from back to front to lower the cover 120.

As the cam 152 makes a second rotation, the proximal end 152b of the cam 152 comes closer to the boss 124 of the cover 120.

In some embodiments, the cover 120 is lowered to the lowest position when the proximal end 152b of the cam 152 is rotated into contact with the boss 124 of the cover 120 or the proximal end 152b of the cam 152 is rotated to the nearest vertical distance from the boss 124.

In a particular implementation, the first rotation is adapted to transition the cam 152 and the lobe 124 from the first contact state to the second contact state, and the second rotation is adapted to transition the cam 152 and the lobe 124 from the second contact state to the first contact state.

Specifically, the first contact state includes a state in which the cam 152 is out of contact with the boss 124 and a state in which the cam 152 is in contact with the boss 124 to apply the first urging force.

In some embodiments, when the cam 152 is out of contact with the boss 124, the lid 120 is in the lowermost position and the drawer 110 is closed.

In some embodiments, when the cam 152 is in contact with the boss 124 to apply the first force, the lid 120 may be positioned between the uppermost position and the lowermost position and open the drawer 110. In this case, the first force applied to the boss 124 by the cam 152 may be utilized to counter the weight of the cover 120 to prevent the cover 120 from moving obliquely downward under its own weight.

The second contact state includes a state in which the cam 152 is in contact with the boss 124 to apply the second force.

In some embodiments, when the cam 152 is in contact with the boss 124 to apply the second force, the lid 120 is in the uppermost position and the drawer 110 is opened. In this case, the second force applied to the boss 124 by the cam 152 may be utilized to counter the weight of the cover 120 to prevent the cover 120 from moving obliquely downward under its own weight.

In some embodiments, when the cam 152 is in contact with the boss 124 to apply the second force, the lid 120 may be in the uppermost position and open the drawer 110. In this case, the second force applied to the boss 124 by the cam 152 may be utilized to counter the gravity of the cover 120 to prevent the cover 120 from moving obliquely downward under its own weight.

In other embodiments, when the cam 152 is in contact with the boss 124 to apply the second force, the lid 120 may be positioned between the uppermost position and the lowermost position and open the drawer 110. In this case, the second force applied to the boss 124 by the cam 152 may be utilized to counter the gravity of the cover 120 to prevent the cover 120 from moving obliquely downward under its own weight.

In a specific implementation, the first force is greater than or equal to zero newtons and less than the second force.

In some embodiments, the protrusion 124 may be perpendicular to the upper surface 121 of the cover 120 and perpendicular to the plane of the first rotation direction and the second rotation direction of the cam 152, so that the cam 152 can push the protrusion 124 more easily, thereby saving energy.

In some embodiments, the protruding portion 124 may also be provided with a reinforcing rib 124a to increase the rigidity of the protruding portion 124, thereby ensuring that the protruding portion 124 may be durable.

In some embodiments, the protrusion 124 may be disposed at an equidistant position with respect to the left and

right sides

122 and 123 of the cover 120 to enable the cover 120 to be smoothly raised or lowered.

In some embodiments, the refrigerator 10 may further include a humidity input unit and a controller. The humidity input unit is used for receiving the set humidity of the drawer 110 input by the user. The controller is configured to control the motor 151 to drive the cam 152 to rotate first to raise the lid 120 to the first position when the set humidity in the drawer 110 is adjusted from the first humidity range to the second humidity range, and control the motor 151 to drive the cam 152 to rotate second to lower the lid 120 to the second position when the set humidity in the drawer 110 is adjusted from the second humidity range to the first humidity range.

In an implementation, the humidity input unit may include a first touch panel. The first touch panel is suitable for sensing input operation of a user to acquire corresponding set humidity. For example, when the user inputs "60% rh" through the first touch panel, the first touch panel may sense the input operation of the user and acquire "60% rh" as the set humidity of the drawer 110. Wherein RH represents Relative Humidity, which is an abbreviation for Relative Humidity.

In the embodiment of the present invention, the humidity in the drawer 110 is adjusted to the set humidity by means of a conventional technique in the art.

In particular implementations, the set humidity may be a specific humidity value or a humidity range.

In particular implementations, any humidity value within the first humidity range is greater than any humidity value within the second humidity range.

In some embodiments, the first humidity range may comprise a humidity interval greater than or equal to 50% RH to less than or equal to 95% RH, and the second humidity range may comprise a humidity interval greater than or equal to 25% RH to less than 50% RH.

In a specific implementation, the humidity in the drawer 110 is adjusted to a first humidity range suitable for storing food materials such as fruits and vegetables, so as to keep the food materials permanently moist and fresh. Adjusting the humidity in the drawer 110 to a second humidity range is suitable for storing food materials such as seafood and chilled meat to reduce nutrient loss of the food materials and maintain meat quality.

In some embodiments, the refrigerator 10 may further include a temperature input unit and a controller. The temperature input unit is used for receiving the set temperature of the refrigeration compartment 100 input by the user. The controller is used for controlling the motor 151 to drive the cam 152 to rotate first to enable the cover 120 to ascend to the first position when the set temperature of the refrigerating compartment 100 is adjusted from the first temperature range to the second temperature range, and controlling the motor 151 to drive the cam 152 to rotate second to enable the cover 120 to descend to the second position when the set temperature is adjusted from the second temperature range to the first temperature range.

In a specific implementation, the temperature input unit may include a second touch panel. The second touch panel is suitable for sensing input operation of a user to acquire a corresponding set temperature. For example, when the user inputs "-18 degrees celsius" through the second touch panel, the second touch panel may sense the input operation of the user and acquire "-18 degrees celsius" as the set temperature of the refrigerating compartment 100.

In the present embodiment, the adjustment of the temperature in the refrigeration compartment 100 to the set temperature is achieved by means conventional in the art.

In particular implementations, the set temperature may be a specific temperature value or a temperature range.

In a specific implementation, any temperature value within the first temperature range is greater than any temperature value within the second temperature range.

In some embodiments, the first temperature range includes a temperature interval greater than or equal to 0 degrees celsius to less than or equal to 12 degrees celsius. The second temperature range includes a temperature range greater than or equal to-20 degrees celsius to less than 0 degrees celsius.

In a specific implementation, adjusting the set temperature of the refrigeration compartment 100 to a first temperature range is suitable for using the refrigeration compartment 100 as a conventional fresh food compartment, and adjusting the set temperature of the refrigeration compartment 100 to a second temperature range is suitable for using the refrigeration compartment 100 as a conventional freezer or ice temperature compartment.

In some embodiments, the first position in which the cover 120 is located may include an uppermost position in which it may be moved upwardly. The motor 151 is adapted to raise the cover 120 to the uppermost position when the set temperature is adjusted to be within the third temperature range.

In a specific implementation, the third temperature range is within the second temperature range.

In some embodiments, the third temperature range includes a temperature interval greater than or equal to-20 degrees Celsius to less than or equal to-18 degrees Celsius.

In a specific implementation, adjusting the set temperature of the refrigeration compartment 100 to the third temperature range is suitable for allowing the refrigeration compartment 100 to be used as a conventional freezer compartment.

In other embodiments, the first position of the cover 120 includes an intermediate position between its uppermost and lowermost positions. The motor 151 is adapted to raise the cover 120 to the intermediate position when the set temperature is adjusted to be within the fourth temperature range.

In a specific implementation, the fourth temperature range is within the second temperature range, and any temperature value within the fourth temperature range is greater than any temperature value within the third temperature range.

In some embodiments, the fourth temperature range includes a temperature interval greater than or equal to-12 degrees Celsius to less than or equal to-6 degrees Celsius.

In a specific implementation, adjusting the set temperature of the refrigeration compartment 100 to the fourth temperature range is suitable for allowing the refrigeration compartment 100 to be used as a conventional ice thermal compartment.

The embodiment of the invention also provides a method for adjusting the cover of the drawer in the refrigerating chamber. The refrigeration compartment 100 is included in the refrigerator 10 according to the embodiment of the present invention.
