When the humidity control knob 51 rotates, the first input belt pulley 534 drives the first lead screw 536 to rotate through the first output belt pulley 535, and the first nut 537 moves along the first lead screw 536; meanwhile, the second input pulley 544 drives the second lead screw 546 to rotate through the second output pulley 545, and the second nut 547 moves along the second lead screw 546; due to the fact that the first lead screw 536 and the second lead screw 546 are rotated in opposite directions, the first nut 537 and the second nut 547 can be synchronously moved in the vertical direction to drive the humidity control cover plate 2 to rotate around the first rotating shaft 4, so that the gap between the humidity control cover plate 2 and the humidity control drawer 1 is changed.
Both of the above-mentioned embodiments of the first sub-transmission mechanism 53 and the second sub-transmission mechanism 54 can change the gap between the humidity control cover plate 2 and the humidity control drawer 1, but compared with the latter (the structure shown in fig. 13), the former (the structure shown in fig. 6 and 9) drives the humidity control cover plate 2 to rotate around the first rotating shaft 4 through the guide on the slider, so that the first sub-transmission mechanism 53 and the second sub-transmission mechanism 54 have simpler structures and are more convenient to install, and a lead screw with higher price does not need to be arranged, thereby being beneficial to reducing the manufacturing cost of the adjusting device 5.
In the embodiment in which the first sub transmission mechanism 53, the second sub transmission mechanism 54 and the humidity control knob 51 constitute the slider-crank mechanism, the positional relationship between the first slider 532, the second slider 542 and the humidity control knob 51 is not unique, for example, the first slider 532 and the second slider 542 may be respectively located on both sides of the humidity control knob 51, specifically, as shown in fig. 6 and 9, the humidity control knob 51 is located at the middle of the front end portion of the shelf 3 in the extending direction X of the first rotating shaft 4, the first slider 532 and the second slider 542 are respectively located on both sides of the humidity control knob 51 opposite to each other in the extending direction X of the first rotating shaft 4, and the connecting lines of the connecting points of the first link 531 and the second link 541 and the humidity control knob 51 pass through the rotation center of the humidity control knob 51; as shown in fig. 6, the first guide surface 5331 and the second guide surface 5431 are higher at both ends closer to the humidity control knob 51 than at the ends farther from the humidity control knob 51 in the extending direction X of the first rotating shaft 4. In this embodiment, since the connecting lines of the connecting points of the first and second links 531, 541 and the humidity control knob 51 pass through the rotation center of the humidity control knob 51, when the humidity control knob 51 rotates, the first and second links 531, 541 can drive the first and second sliders 532, 542 to move in opposite directions; since the ends of the first guide surface 5331 and the second guide surface 5431 close to the humidity control knob 51 are higher than the ends far from the humidity control knob 51, the first guide surface 5331 and the second guide surface 5431 can guide the first bridging portion 21 and the second bridging portion 22 to move synchronously in the vertical direction as the first slider 532 and the second slider 542 slide in opposite directions relative to the shelf 3, so that the humidity control cover 2 can rotate around the first rotating shaft 4 to adjust the gap between the humidity control cover 2 and the humidity control drawer 1.
In addition, the first slider 532 and the second slider 542 may be located on the same side of the humidity control knob 51, and specifically, as shown in fig. 11, the first slider 532 and the second slider 542 are located on the same side of the humidity control knob 51 in the extending direction of the first rotating shaft 4; in the extending direction X of the first rotating shaft 4, the first guide surface 5331 and the second guide surface 5431 are higher at the end close to the humidity control knob 51 than at the end far from the humidity control knob 51. In this embodiment, when the humidity control knob 51 rotates, the first link 531 and the second link 541 can respectively drive the first slider 532 and the second slider 542 to slide relative to the shelf 3 along the same direction; because the ends of the first guide surface 5331 and the second guide surface 5431 close to the humidity control knob 51 are higher than the ends far away from the humidity control knob 51, when the first slider 532 and the second slider 542 slide relative to the shelf 3, the first guide surface 5331 and the second guide surface 5431 can ensure that the first bridging portion 21 and the second bridging portion 22 can be guided to synchronously move in the vertical direction, so that the humidity control cover plate 2 can rotate around the first rotating shaft 4 to adjust the gap between the humidity control cover plate 2 and the humidity control drawer 1. Compared with the embodiment in which the first slider 532 and the second slider 542 are located on the same side of the humidity control knob 51, in the embodiment in which the first slider 532 and the second slider 542 are located on two sides of the humidity control knob 51, the first guide 533 and the second guide 543 with the same structure can be symmetrically arranged on two sides of the humidity control knob 51, and design parameters of the first guide 533 and the second guide 543 do not need to be changed, so that design and manufacture of the first sub-transmission mechanism 53 and the second sub-transmission mechanism 54 are facilitated, and design and manufacture costs of the first sub-transmission mechanism 53 and the second sub-transmission mechanism 54 are reduced.
The types of the first guide surface 5331 and the second guide surface 5431 are not exclusive, and for example, as shown in fig. 6 and 7, the first guide surface 5331 and the second guide surface 5431 may be both planar; in addition, the first guide surface 5331 and the second guide surface 5431 may be both arc surfaces. Compared with an arc surface, when the first guide surface 5331 and the second guide surface 5431 are both flat surfaces, the processing difficulty of the first guide surface 5331 and the second guide surface 5431 can be reduced, so that the processing cost of the first guide piece 533 and the second guide piece 543 can be reduced.
The types of the crank-slider mechanisms formed by the first sub-transmission mechanism 53, the second sub-transmission mechanism 54 and the humidity control knob 51 are not exclusive, and for example, all of the crank-slider mechanisms may be centering crank-slider mechanisms, and as shown in fig. 9, a connection point a of the first link 531 and the first slider 532, a connection point b of the second link 541 and the second slider 542, and a rotation center c of the humidity control knob 51 are located on a same straight line, and the straight line is parallel to the extending direction X of the first rotating shaft 4. In addition, both of the offset slider-crank mechanisms may be used, that is, the rotational center of the humidity control knob 51 is located outside the straight line formed by the connection point between the first link 531 and the first slider 532 and the connection point between the second link 541 and the second slider 542. Compared with an offset crank slider mechanism, the centering crank slider mechanism has no quick return characteristic, so that when the humidity control rotation speed is constant, the movement speed of the forward stroke and the movement speed of the return stroke of the first slider 532 and the second slider 542 can be the same, the speed of the humidity control cover plate 2 around the first rotating shaft 4 can be ensured to be stable, the adjusting speed of the gap between the humidity control cover plate 2 and the humidity control drawer 1 can be further stable, and a better humidity control effect can be ensured.
In the adjustment device 5, the positions of the first slider 532, the second slider 542, and the humidity control knob 51 are not limited, and may be set as follows: as shown in fig. 9 and 10, the lower surface of the front end of the shelf 3 is provided with a first slide groove 31 and a second slide groove 32 spaced apart from each other along the extending direction X of the first rotating shaft 4, the extending directions of the first slide groove 31 and the second slide groove 32 are both parallel to the extending direction X of the first rotating shaft 4, the first slider 532 is slidably engaged with the first slide groove 31, and the second slider 542 is slidably engaged with the second slide groove 32; the front end part of the shelf 3 is provided with a mounting through hole 33, the central axis of the mounting through hole 33 is vertically arranged, and the humidity control knob 51 is arranged through the mounting through hole 33 and a part of the humidity control knob extends out of the lower end of the mounting through hole 33; the first end of the first link 531 and the first end of the second link 541 are both rotatably connected to the part of the humidity control knob 51 extending out of the lower end of the mounting through hole 33. In order to ensure that the first slider 532 and the second slider 542 do not slide out of the first sliding groove 31 and the second sliding groove 32 respectively under the action of gravity, the groove width at the groove opening of the first sliding groove 31 and the second sliding groove 32 is smaller than that at the groove bottom along the direction from top to bottom, and the movement of the first slider 532 and the second slider 542 in the vertical direction can be limited by the arrangement, so that the first slider 532 and the second slider 542 are prevented from sliding out of the first sliding groove 31 and the second sliding groove 32 respectively under the action of gravity.
In addition, the following setting modes can be adopted: as shown in fig. 14 and 15, the front end of the shelf 3 has a mounting groove 34, the extending direction of the mounting groove 34 is parallel to the extending direction X of the first rotating shaft 4, the notch of the mounting groove 34 faces the inside of the storage chamber 200, and the first slider 532 and the second slider 542 are arranged in the mounting groove 34 at intervals along the extending direction X of the first rotating shaft 4 and are both connected with the lower groove wall of the mounting groove 34 in a sliding manner; an assembly through hole 35 communicated with the mounting groove 34 is formed in the front end part of the shelf 3, the central axis of the assembly through hole 35 is horizontally arranged, and the humidity control knob 51 penetrates through the assembly through hole 35 and partially extends into the mounting groove 34; the first end of the first link 531 and the first end of the second link 541 are both rotatably connected to the part of the humidity control knob 51 extending into the mounting groove 34. In the former (the embodiment shown in fig. 9 and 10), the arrangement among the first slider 532, the second slider 542, the humidity control knob 51 and the shelf 3 is more compact than the latter (the embodiment shown in fig. 14 and 15), and the installation space of the humidity control drawer 1 in the front-rear direction is avoided by the installation groove 34 provided at the front end portion of the shelf 3, so that the volume of the humidity control drawer 1 can be increased when the size of the storage chamber 200 is constant.
In the adjusting device 5, there are various setting manners between the first guide 533 and the first slider 532, and between the second guide 543 and the second slider 542, for example, the first guide 533 and the second guide 543 may be respectively disposed below the first slider 532 and the second slider 542, specifically, as shown in fig. 6 and 7, the first guide 533 is disposed on the lower surface of the first slider 532, a first setting space 539 is provided between the first guide surface 5331 and the first slider 532, and the first overlapping portion 21 extends into the first setting space 539 and overlaps the first guide surface 5331; the second guide 543 is disposed on the lower surface of the second slider 542, and a second disposition space 549 is provided between the second guide surface 5431 and the second slider 542, and the second overlapping portion 22 extends into the second disposition space 549 and overlaps on the second guide surface 5431.
In addition, the first guide 533 and the second guide 543 may be respectively disposed on one side of the first slider 532 and the second slider 542 along the horizontal direction, that is: a portion of the first slider 532 protrudes out of the first sliding chute 31, and the first guide 533 is provided on a side surface of the portion of the first slider 532 protruding out of the first sliding chute 31; a portion of the second slider 542 protrudes out of the second slide groove 32, and a second guide 543 is provided on a side surface of the portion of the second slider 542 that protrudes out of the second slide groove 32. Compared with the first guide 533 and the second guide 543 respectively arranged at one side of the first slider 532 and the second slider 542 along the horizontal direction, when the first guide 533 and the second guide 543 are respectively arranged below the first slider 532 and the second slider 542, in the process of adjusting the gap between the humidity control cover plate 2 and the humidity control drawer 1, the acting force of the first guide 533 and the second guide 543 on the first slider 532 and the second slider 542 is applied to the lower surface thereof, so that the first slider 532 and the second slider 542 are more easily kept in balance, and the stability of the movement of the first slider 532 and the second slider 542 is ensured.
In the adjusting device 5, the structure of the third sub-transmission machine is not exclusive, and may be, for example, the following structure: as shown in fig. 6, the third sub-transmission mechanism 55 includes a third guide 551, and the third guide 551 is connected to the humidity control knob 51; the humidity control cover plate 2 is also provided with a third lapping part 23, and the third lapping part 23 is lapped on the third guide 551; the portion where the third overlapping portion 23 overlaps the third guide 551 is the connection point 6 corresponding to the third sub-transmission mechanism 55.
