Document Type and Number:
WIPO Patent Application WO/2019/129069
Kind Code:
A1
Abstract:
A configuration sensing device (480), a multiway air distribution device (400) and a refrigerator (1). The configuration sensing device (480) comprises: a rotating structure (486), the rotating structure (486) being provided with a plurality of protrusions (482), the plurality of protrusions (482) being sequentially provided at intervals along the rotating direction of the rotating structure; and a switch (483) assembly (481), the switch (483) assembly (481) having a plurality of switches (483) and a plurality of levers (484); one end of each lever (484) being placed on the rotating structure (486) to slide on the rotating structure (486) upon rotation of the rotating structure (486), so as to act, when moving to each protrusion (482), on the corresponding switch (483) in a first manner, and act, when moving to the recessed portion outside each protrusion (482), on the corresponding switch (483) in a second manner; and each switch (483) having two states of opening and closing, the plurality of protrusions (482) and the plurality of levers (484) being configured to enable the plurality of switches (483) to have multiple opening and closing state combinations, such that each opening and closing state combination represents one configuration. The configuration sensing device (480) is capable of sensing the respective states of the circumferentially operated components, so as to reflect the corresponding configuration.
