Opening and closing structure, component having opening and closing structure and washing machine having component

Abstract

Provided are an opening and closing structure, a component, and a washing machine. The opening and closing structure includes: a supporting body formed with an opening part; and the lid supported by the supporting body in a free rotation manner. An elastic deformation part forming a rotation center and a periphery of the lid has flexibility. One of the supporting body and the elastic deformation part is provided with a shaft forming the rotation center of the lid, and the other is provided with a hole insertable by the shaft. One of the supporting body and the elastic deformation part is provided with a pin, and the other is provided with a recess receivable to the pin with a clearance during opening and closing of the lid. The recess gradually becomes shallower as the lid goes from an open position to an opposite side of a closed position.

1 . An opening and closing structure, comprising:
 a supporting body, which is formed with an opening part;   a lid, which is supported by the supporting body in a free rotation manner, and is capable of being opened and closed between an open position at which the opening part is opened and a closed position at which the opening part is closed;   an elastic deformation part, which forms a rotation center and a periphery of the lid and has flexibility;   a shaft, which is provided on one of the supporting body and the elastic deformation part, and is formed as the rotation center of the lid;   a hole, which is provided on the other of the supporting body and the elastic deformation part which is not provided with the shaft, and is insertable by the shaft;   a pin, which is provided on one of the supporting body and the elastic deformation part; and   a recess, which is provided on the other of the supporting body and the elastic deformation part which is not provided with the pin, and is receivable to the pin with a clearance during opening and closing of the lid,   wherein the recess gradually becomes shallower as the lid goes from the open position to an opposite side of the closed position, so as to push the pin out.   
     
     
         2 . The opening and closing structure according to  claim 1 , comprising a slit, which is formed at the lid and is configured to bend the elastic deformation part. 
     
     
         3 . A component, comprising the an opening and closing structure including:
 a supporting body, which is formed with an opening part;   a lid, which is supported by the supporting body in a free rotation manner, and is capable of being opened and closed between an open position at which the opening part is opened and a closed position at which the opening part is closed;   an elastic deformation part, which forms a rotation center and a periphery of the lid and has flexibility;   a shaft, which is provided on one of the supporting body and the elastic deformation part, and is formed as the rotation center of the lid;   a hole, which is provided on the other of the supporting body and the elastic deformation part which is not provided with the shaft, and is insertable by the shaft;   a pin, which is provided on one of the supporting body and the elastic deformation part; and   a recess, which is provided on the other of the supporting body and the elastic deformation part which is not provided with the pin, and is receivable to the pin with a clearance during opening and closing of the lid,   wherein the recess gradually becomes shallower as the lid goes from the open position to an opposite side of the closed position, so as to push the pin out.   
     
     
         4 . A washing machine, comprising a component, including:
 a supporting body, which is formed with an opening part;   a lid, which is supported by the supporting body in a free rotation manner, and is capable of being opened and closed between an open position at which the opening part is opened and a closed position at which the opening part is closed;   an elastic deformation part, which forms a rotation center and a periphery of the lid and has flexibility;   a shaft, which is provided on one of the supporting body and the elastic deformation part, and is formed as the rotation center of the lid;   a hole, which is provided on the other of the supporting body and the elastic deformation part which is not provided with the shaft, and is insertable by the shaft;   a pin, which is provided on one of the supporting body and the elastic deformation part; and   a recess, which is provided on the other of the supporting body and the elastic deformation part which is not provided with the pin, and is receivable to the pin with a clearance during opening and closing of the lid,   wherein the recess gradually becomes shallower as the lid goes from the open position to an opposite side of the closed position, so as to push the pin out; and   the opening part is a feeding port for feeding any of detergent, softener and bleach.   
     
     
         5 . The component according to  claim 3 , comprising a slit, which is formed at the lid and is configured to bend the elastic deformation part. 
     
     
         6 . The washing machine according to  claim 4 , comprising a slit, which is formed at the lid and is configured to bend the elastic deformation part.
