The refrigerator with the humidity adjusting drawer according to the embodiment of the present invention, as shown in fig. 1, includes a refrigerating chamber (not shown in the figure), a storage drawer 1 is disposed in the refrigerating chamber, a drawer cover plate 2 is covered at an opening of the storage drawer 1, and the storage drawer 1 can be sealed by the drawer cover plate 2 to prevent cold air from blowing into the storage drawer 1. Meanwhile, in order to adjust the humidity in the storage drawer 1, a fixing frame 3 fixed to the refrigerating chamber is provided above the drawer cover 2, as shown in fig. 2 and 3, an adjusting button 4 is rotatably connected to the fixing frame 3 in the vertical direction, a screw adjuster 5 is connected below the adjusting button 4, as shown in fig. 4 and 5, a fan-shaped spiral ring 51 is provided in the circumferential direction of the screw adjuster 5, and the height of the fan-shaped spiral ring 51 in the vertical direction gradually changes in a slope shape, as shown in fig. 6 and 7, a hook portion 21 extends toward the fixing frame 3 above the drawer cover 2, and the upper surface of the fan-shaped spiral ring 51 is in sliding contact with the lower surface of the hook portion 21, so that, referring to fig. 2 and 3 again, when the adjusting button 4 is rotated, the adjusting button 4 drives the screw adjuster 5 to rotate together, and further drives the spiral fan-shaped ring 51 to rotate, and the upper surface of the slope-shaped spiral ring 51 is in sliding contact with the lower surface, the drawer cover 2 can be raised or lowered. When the drawer cover plate 2 is lifted, the storage drawer 1 is communicated with the refrigerating chamber, and cold air can be blown into the storage drawer 1 to reduce the temperature and the humidity in the storage drawer 1; when the drawer cover plate 2 is put down, the storage drawer 1 is sealed, cold air cannot blow into the storage drawer 1, and therefore moisture on the surface of food in the storage drawer 1 is prevented from being taken away. Thus, the humidity inside the locker drawer 1 may be adjusted. In addition, the drawer cover plate 2 can be lifted or put down by the simple action of rotating the adjusting button 4, and the operation is simple and convenient.

It should be noted that the lower part of the adjusting button 4 is connected with the screw adjuster 5, and for convenient production, the adjusting button 4, the screw adjuster 5 and the fan-shaped screw ring 51 are integrally formed; however, since the shape and structure of the adjustment button 4, the screw actuator 5 and the fan-shaped screw ring 51 are special, the adjustment button 4 and the screw actuator 5 are divided into two parts for easy installation, and the fan-shaped screw ring 51 may be integrally formed with the screw actuator 5, and the adjustment button 4 and the screw actuator 5 are connected when being installed.

In order to be able to limit the rotation of the adjusting button 4, the screw adjuster 5 and the fan-shaped screw ring 51, as shown in fig. 2 and 3, the adjusting device includes an adjusting cylinder 31 disposed below the fixing frame 3 corresponding to the adjusting button 4, the screw adjuster 5 is disposed in the adjusting cylinder 31 and can rotate in the adjusting cylinder 31, the lower end of the adjusting button 4 extends into the adjusting cylinder 31 and is connected with the screw adjuster 5, as shown in fig. 8 and 9, a limiting groove 311 is disposed on the adjusting cylinder 31 in a circumferential direction corresponding to the fan-shaped screw ring 51, the fan-shaped screw ring 51 passes through the limiting groove 311 to be in sliding contact with the hook portion 21, and the limiting groove 311 is used for limiting the rotation angle of the fan-shaped screw ring 51. Thus, the screw adjuster 5 is positioned in the adjusting cylinder 31 and can rotate in the adjusting cylinder 31, the bottom surface of the adjusting cylinder 31 supports the screw adjuster 5, and the side wall can limit the screw adjuster 5; meanwhile, after the adjusting cylinder 31 is provided, in order that the fan-shaped spiral ring 51 can be matched with the hook portion 21 of the drawer cover 2, a limiting groove 311 is provided in the circumferential direction of the adjusting cylinder 31, the fan-shaped spiral ring 51 can pass through the limiting groove 311 to be in sliding contact with the hook portion 21 of the drawer cover 2, and the limiting groove 311 can limit the rotation angle of the fan-shaped spiral ring 51.

It should be noted that, the length of the two ends (transverse ends) of the limiting groove 311 along the rotation direction of the fan-shaped spiral ring 51 reserves a rotation space for the fan-shaped spiral ring 51, and the two ends are used for limiting the maximum rotation angle; the width of the two ends (longitudinal ends) of the limiting groove 311 perpendicular to the rotation direction of the fan-shaped spiral ring 51 needs to be greater than the height of the fan-shaped spiral ring 51 so that the fan-shaped spiral ring 51 can pass through the limiting groove 311, i.e., the length and width dimensions of the limiting groove 311 are determined according to the dimensions of the fan-shaped spiral ring 51, and the rotation angle to be limited is considered.

The connection between the adjustment button 4 and the screw adjustor 5 may be implemented in various manners, such as a snap-fit manner, a screw connection, an adhesion manner, etc., wherein the snap-fit manner is convenient to install and disassemble and has a simple structure to implement, and therefore, it is preferable that the adjustment button 4 and the screw adjustor 5 are connected by the snap-fit structure.

Specifically, as shown in fig. 10, 11 and 12, the snap structure includes a plurality of snap protrusions 41 provided at a lower end of the adjustment button 4, as shown in fig. 4 and 13, and a plurality of snap grooves 52 provided at an upper surface of the screw adjuster 5, the plurality of snap protrusions 41 are equidistant from a center of the adjustment button 4, and the plurality of snap protrusions 41 may be inserted into the plurality of snap grooves 52 in a one-to-one correspondence. Because the rotation of adjustment button 4 needs to drive spiral adjuster 5 rotatory, if only set up a joint arch 41 and a joint recess 52 cooperation, or the distance inequality at a plurality of joint archs 41 and adjustment button 4's center, all do not do benefit to rotary motion's transmission, consequently, will the one-to-one set up a plurality of joint archs 41 and to a plurality of joint recesses 52, and the distance at a plurality of joint archs 41 and adjustment button 4's center equals.

It should be noted that, the shape and structure of the clamping protrusion 41 may be various, for example, for convenience of manufacturing and installation, as shown in fig. 10, the clamping protrusion 41 is two opposite structures extending downward along the column shape of the adjustment button 4, and both are arc-shaped, which is equivalent to symmetrically opening two notches at the lower end of the cylindrical adjustment button 4 to form two arc-shaped clamping protrusions 41, so that the process manufacturing is convenient, and the transmission of the rotation motion can be ensured; of course, the corresponding snap recesses 52 are also of two opposing arcuate configurations.

In order to fix the adjusting cylinder 31 and the fixing frame 3, as shown in fig. 8 and 14, a fixing seat 312 is provided on an outer side wall of the adjusting cylinder 31, as shown in fig. 15 and 16, the fixing frame 3 is provided with a fixing post 32 corresponding to the fixing seat 312, and the fixing seat 312 and the fixing post 32 are fixedly connected by a fastener to fixedly connect the adjusting cylinder 31 and the fixing frame 3.

Since the fan-shaped spiral ring 51 has a fan shape, if the hook portion 21 of the drawer cover 2 is configured to have a rectangular or other non-fan-shaped structure, it may not smoothly fit with the fan-shaped spiral ring 51 and is easily separated from the fan-shaped spiral ring, and therefore, in order to smoothly and easily separate the hook portion 21 of the drawer cover 2 from the fan-shaped spiral ring 51, referring to fig. 7, the hook portion 21 has a fan-shaped structure and is concentrically disposed with the fan-shaped spiral ring 51.

The action of lifting the drawer cover 2 may be complete lifting or one end lifting. Wherein, in the scheme that drawer apron 2 lifted up completely, if only set up one set of mechanism that lifts up (including adjustment button 4, helical adjustment ware 5, fan-shaped spiral ring 51 and couple portion 21), drawer apron 2 probably because the unbalanced atress can't lift up completely, consequently, need set up a plurality of adjustment button 4, helical adjustment ware 5, fan-shaped spiral ring 51 and couple portion 21 to make a plurality of positions atress of drawer apron 2, and then drawer apron 2 can lift up completely. Therefore, the operation is troublesome and the structure is complicated. In the scheme that the one end of drawer apron 2 was lifted up, in order to guarantee to put down drawer apron 2 again after lifting up at every turn and can correctly be sealed with storage drawer 1, drawer apron 2 is kept away from the other end that lifts up one end and needs the location, promptly with storage drawer 1 or mount 3 swivelling joint. Since the storage drawer 1 needs to be drawn out of the refrigerating chamber when food is placed or taken out, it is preferable that the drawer cover 2 is rotatably coupled to the fixing frame 3. Meanwhile, in order to facilitate observation and operation, it should be preferable that one end of the drawer cover 2 near the outside of the refrigerating chamber is lifted. As shown in fig. 1 and 6, the hook portion 21 is provided near the outside of the refrigerating compartment, and the drawer cover 2 and the fixing frame 3 are rotatably coupled at a position near the inside of the refrigerating compartment.

It should be noted that there are various ways of rotatably connecting the drawer cover 2 and the fixing frame 3, referring to fig. 6 and 17, for one of them, the hinge shaft 22 is disposed on the drawer cover 2, the hinge hole 33 is disposed on the fixing frame 3 referring to fig. 18, and the hinge shaft 22 is matched with and extends into the hinge hole 33, so that the rotatable connection of the drawer cover 2 and the fixing frame 3 can be realized.

In order to guide and limit the lifting action of one end of the drawer cover 2, referring to fig. 6 and 17, a guide groove 23 is arranged on the drawer cover 2 close to the outside of the refrigerating chamber, the guide groove 23 extends along the vertical direction, referring to fig. 15, a guide post 34 is arranged on the fixed frame 3 corresponding to the guide groove 23, and the guide post 34 is matched with and extends into the guide groove 23 and can slide along the guide groove 23.

It should be noted that the action of lifting one end of the drawer cover 2 is rotating around the other end, and the motion track is arc-shaped, but because the action range of lifting one end of the drawer cover 2 is small, for convenience of manufacture, the guide groove 23 extends along the vertical direction, and of course, the width of the guide groove 23 can be properly widened to adapt to the arc-shaped motion track, or the guide groove 23 is set to be arc-shaped according to the motion track of lifting the drawer cover 2.

Referring to fig. 1 and 19, a plurality of drawers 1 are stacked in a general refrigerator, and the adjustment button 4 is elevated above the holder 3 for user's operation, and the upper drawer 1 is appropriately reduced to avoid the lower adjustment button 4 so as not to be blocked by the upper drawer 1 when the lower adjustment button 4 is operated. However, when the upper storage drawer 1 is pulled out or pushed back, the adjustment button 4 for controlling the lifting or lowering of the drawer cover 2 of the lower storage drawer 1 may also interfere with the bottom of the upper storage drawer 1 and collide with the bottom, causing damage to the adjustment button 4 or making it difficult for the upper storage drawer 1 to be pulled out or pushed back. Therefore, in order to prevent the lower adjusting button 4 from interfering and colliding with the upper storage drawer 1, as shown in fig. 15 and 16, the fixing frame 3 is provided with a mounting seat 35 extending vertically downward corresponding to the adjusting button 4, referring to fig. 2, the adjusting button 4 is positioned in the mounting seat 35 and can rotate in the mounting seat 35 and move in the vertical direction along the inner wall of the mounting seat 35, a locking mechanism 6 and a rebound mechanism 7 are arranged between the adjusting button 4 and the mounting seat 35, when the adjusting button 4 moves vertically downward along the inner wall of the mounting seat 35 and moves from the initial position above the fixing frame 3 to the hidden position below the fixing frame 3, the locking mechanism 6 is used for fixing the relative position of the adjusting button 4 and the fixing frame 3, and when the locking mechanism 6 releases the locking function, the rebound mechanism 7 is used for applying a vertically upward rebound force to the adjusting button 4 to move the adjusting button 4 vertically upward along the inner wall of the mounting seat 35, and the hidden position is restored to the initial position.

In this way, before the upper storage drawer 1 needs to be withdrawn, the adjustment button 4 is pressed to move from the initial position to the concealed position, at which time the locking mechanism 6 fixes the relative position of the adjustment button 4 and the holder 3, and the upper storage drawer 1 can be withdrawn normally without interfering with the adjustment button 4. When the adjusting button 4 needs to be operated, the locking function of the locking mechanism 6 is released, and the adjusting button 4 can be restored to the initial position from the hidden position through the function of the rebound mechanism 7, so that the adjusting button 4 can be normally operated.

The specific mechanism of the locking mechanism 6 is as shown in fig. 2 and 3, the locking mechanism 6 includes a mounting ring 61 disposed outside the mounting seat 35, as shown in fig. 20, a cylindrical protrusion 611 extends from an inner side wall of the mounting ring 61 toward a center of the adjustment button 4, as shown in fig. 16, a first stepped through groove 351 and a second stepped through groove 352 which are communicated with each other are disposed on the mounting seat 35 along a vertical direction, a protruding rib 353 is disposed between the first stepped through groove 351 and the second stepped through groove 352, the height of the first stepped through groove 351 in the vertical direction is greater than that of the second stepped through groove 352, as shown in fig. 10 and 11, an annular groove 42 and a plurality of V-shaped grooves 43 communicated with the annular groove 42 are disposed in a circumferential direction of the adjustment button 4, two ends of the plurality of V-shaped grooves 43 are communicated with the annular groove 42, and a height of a bending portion thereof in the vertical direction is greater;

when the adjusting button 4 is located at the initial position, the cylindrical protrusion 611 passes through the first stepped through groove 351 to be matched with the annular groove 42, and when the adjusting button 4 is located at the hidden position, the cylindrical protrusion 611 passes through the second stepped through groove 352 to be matched with the bent part of the V-shaped groove 43; the rib 353 serves to prevent the cylindrical protrusion 611 passing through the second stepped through groove 352 from sliding into the first stepped through groove 351.

Thus, when the adjusting button 4 is located at the initial position, the adjusting button 4 is pressed to enable the cylindrical protrusion 611 to slide into the bent part of the V-shaped groove 43 from the annular groove 42 and rotate for a certain angle under the driving of the V-shaped groove, so that the cylindrical protrusion 611 passes over the convex rib 353 and passes through the second stepped through groove 352, and the adjusting button 4 moves from the initial position to the hidden position; when the adjusting button 4 is located at the hidden position, the adjusting button 4 is pressed again, so that the cylindrical protrusion 611 slides into the annular groove 42 from the bending part of the V-shaped groove 43, and rotates by a certain angle under the driving of the V-shaped groove, so that the cylindrical protrusion 611 passes over the convex rib 353 and passes through the second stepped through groove 352, and then the adjusting button 4 moves to the initial position from the hidden position.

It should be noted that the cylindrical protrusion 611 is configured to be cylindrical, and is more easily slidable than other shapes. In addition, in order to make the force applied to the mounting ring 61 uniform, a plurality of cylindrical protrusions 611 may be provided and uniformly distributed along the inner circumferential direction of the mounting ring 61, as shown in fig. 20, three cylindrical protrusions 611 are uniformly distributed along the inner circumferential direction of the mounting ring 61. Of course, as shown in fig. 16, there are a plurality of first stepped through grooves 351, second stepped through grooves 352 and ribs 353; referring to fig. 10 and 11, the annular groove 42 and the plurality of V-grooves 43 also need to be provided corresponding to the plurality of cylindrical protrusions 611.

As shown in fig. 19, in order not to be obstructed by the upper locker drawer 1 when the lower adjustment button 4 is operated, the upper locker drawer 1 may be suitably contracted to avoid the lower adjustment button 4.

The rebound mechanism 7 can be a spring or other elastic member, specifically, as shown in fig. 2 and 3, the rebound mechanism 7 is a spring disposed in the adjusting cylinder 31, an upper end of the spring abuts against an inner top wall of the adjusting button 4, and a lower end of the spring abuts against an inner bottom surface of the adjusting cylinder 31.

In order to position the spring, as shown in fig. 3, a first positioning cylinder 44 vertically extends downward from the inner top wall of the adjusting button 4, a second positioning cylinder 36 vertically extends upward from the inner bottom surface of the adjusting cylinder 31, the second positioning cylinder 36 has a cavity 361 with an upward opening, the upper end of the spring is sleeved outside the first positioning cylinder 44, and the lower end of the spring extends into the cavity 361 of the second positioning cylinder 36.
