[0002] With the development of the economy and the continuous improvement of consumers' living standards, refrigerators have become an indispensable household appliance in daily life. Early refrigerators did not have the function of adjusting humidity and could only keep food fresh. However, due to the refrigeration method of frost-free refrigerators, forced convection will be formed in the refrigerator room, which will accelerate the evaporation of moisture from the food in the refrigerator, and the food cannot be kept fresh for a long time. In response to this deficiency, a refrigerator capable of adjusting the humidity inside the refrigerator has been proposed in the prior art. However, the humidity control structure in the current refrigerator has a travel limit when rotating to adjust the humidity control structure, and there is a risk of damage due to exceeding the travel limit during use. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide a humidity regulating component, a humidity regulating structure, and a refrigerator, wherein the shaft of the humidity regulating component can rotate without travel restriction, thereby effectively eliminating the risk of damage caused by the shaft rotating beyond the travel in the prior art.

[0007] Preferably, the second outer ring wall is constructed with a plurality of grooves adjacent to each other along the moving direction of the reciprocating member, and also includes a damping component, which includes an abutment member capable of entering and exiting the groove and a damping member that generates a thrust toward one side of the groove on the abutment member.

[0008] Preferably, the abutment member has a protrusion matching the groove and a guide rod, the housing is provided with a guide sleeve, the guide rod is inserted into the guide sleeve and can generate linear motion during the movement of the reciprocating member.

DETAILED DESCRIPTION

[0023] See also Figures 1 to 5As shown, according to an embodiment of the present invention, a humidity regulating component is provided, including a shell 1, the shell 1 is in a box structure, a reciprocating member 2 is arranged in the inner cavity of the shell 1, the reciprocating member 2 includes an annular body 21 and a connecting portion 22 connected to the refrigerator humidity regulating baffle 100, the annular body 21 has relatively parallel inner ring walls, and the relatively parallel inner ring walls are respectively provided with teeth 23, and also includes a rotating shaft 3, the rotating shaft 3 has a gear 31, the outer peripheral wall of the gear 31 has a tooth portion 311 and a toothless portion 312, the tooth portion 311 and the toothless portion 312 are arranged in sequence in a circumferential direction of the outer peripheral wall, and the gear 31 can engage or disengage with the teeth 23. In this technical solution, the rotating shaft 3 selectively meshes or disengages with the annular body 21 through a gear 311 having a tooth portion 311 and a toothless portion 312, thereby driving the refrigerator humidity control baffle 100 to move through the reciprocating linear motion of the annular body 21. It can be understood that the linear reciprocating motion of the refrigerator humidity control baffle 100 can change the flow area of ​​the corresponding structure in the refrigerator, thereby adjusting the humidity of the corresponding structure in the refrigerator. In the present invention, the gear 311 having a tooth portion 311 and a toothless portion 312 is used to selectively mesh or disengage with the annular body 21, such as the meshing or disengagement of the tooth portion 311 with the tooth teeth 23. When the shaft 3 rotates clockwise, the annular body 21 will no longer move toward this side because the tooth portion 311 is disengaged from the tooth 23 when the annular body 21 moves linearly to the limit on one side (for example, the left side). Assuming that this corresponds to the maximum humidity position, and further rotating clockwise at this position, the annular body 21 will move linearly in the opposite direction (that is, corresponding to the direction of humidity reduction, that is, for example, the right side corresponding to the aforementioned left side). That is, there is no limit on the stroke of the rotation of the shaft 3, which effectively eliminates the risk of damage caused by the shaft rotating beyond the stroke in the prior art. It can be understood that in specific applications, the rotation direction and humidity of the knob 5 corresponding to the shaft 3 should be calibrated as necessary to clarify the relationship between the rotation direction of the shaft 3 and the humidity adjustment direction.

A guide sleeve is constructed on the shell 1. The guide rod 412 is inserted into the guide sleeve and can generate linear motion during the movement of the reciprocating member 2. The protrusion 411 can escape from the previous groove in the groove 27 and enter another adjacent groove during the movement of the reciprocating member 2. This structure can give the user positive feedback when the user rotates the knob 5 to adjust the humidity. Furthermore, the number of the grooves 27 is preferably the same as the humidity adjustment gear of the humidity adjustment component.
