The pivot shaft member 140 may be rotationally combined with a combiner (not shown) of the upper frame 37 for pivotally supporting the container cover 130. The pivot shaft member 140 may be configured to be drawn to the inside of the container cover 130 or drawn out of the container cover 130.
Specifically, the container cover 130 may include a first cover 131, a second cover 132, an elastic member 133, and a guide bracket 134.
While the container cover 130 holds the detergent container 110 shut, the first cover 131 may form an upper exterior of the container cover 130 and the second cover 132 may form a lower exterior of the cover 130.
The elastic member 133 may be fixed to a portion on the inner side of the container cover 130 at one end and may be connected to the pivot shaft member 140 at the other end. The elastic member 133 may be provided to press the pivot shaft member 140 outwards from the container cover 130.
The guide bracket 134 may be coupled to the inner side of the first cover 131 or the second cover 132 for guiding the movement of the pivot shaft member 140. The guide bracket 134 may be coupled to the first cover 131 by screwing. One end of the elastic member 133 may be fixed to the guide bracket 134.
The guide bracket 134 may include a guide protrusion 134a inserted to a guide recess 143 of the pivot shaft member 140 for supporting the pivot shaft member 140 to be able to slide. The guide bracket 134 may include a shaft hole 134b into which an axial shaft 142 of the pivot shaft member 140 may be slidingly inserted.
The pivot shaft member 140 may include a lever 141 to be slidingly inserted to a lever hole 132a of the second cover 132. The lever 141 may protrude outwards from the container cover 130 for the user to be able to manipulate the pivot shaft member 140.
The pivot shaft member 140 may be slidingly inserted to the shaft hole 134b of the guide bracket 134 and may include the axial shaft 142 to be inserted to the combiner of the upper frame 37. The axial shaft 142 may be drawn into the inner side of the container cover 130 or may protrude outward from the container cover 130.
The pivot shaft member 140 may include the guide recess 143 into which the guide protrusion 134a of the guide bracket 134 is inserted. The guide recess 143 may be formed on the inner side of a substantially ringed protrusion 144 and may have substantially the same size and shape as the cross-section of the guide protrusion 134a.

The pivot shaft member 140 as described above may be arranged at the left end and/or right end of the container cover 130. In a case that the pivot shaft member 140 is arranged at one of the left and right ends, a pivot shaft 146 simply fixed to the first cover 131 or the second cover 132 may be arranged at the other end. The pivot shaft 146 may include an axial shaft part 147, which may be rotationally combined with the combiner (not shown) of the upper frame 37.
With the configurations, the washing machine 1 in accordance with an embodiment of the present disclosure may allow the container cover 130 to cover the detergent container 110 to be easily separated from or combined with the second housing 35.
The container cover 130 may include a first recess 135 formed on the top of an end toward the second door 80. The rear end of the top of the container cover 130 may have the first recess 135 sunken down. The first recess 135 may be concavely formed in and second bottom doors 135 and 80 may be pivotally opened or closed in a receding direction from the second door 80.
The user may be able to lift the front end of the second door 80 through the space formed by the first recess 135 between the front end of the second door 80 and the container cover 130. Accordingly, the washing machine 1 may open the second laundry inlet 21 by pivoting the second door 80 even while the container cover 130 holds the detergent container 110 shut.
In a portion of the upper frame 37 that corresponds to the front end of the container cover 130, a second recess 37b sunken in a receding direction from the container cover 130 may be formed. In a portion of the upper frame 37 that corresponds to the other end opposite an end at which the pivot shaft member 140 is arranged, the second recess 37b sunken in a receding direction from the container cover 130 may be formed.
The user may be able to lift the container cover 130 through the space formed by the second recess 37b between the front end of the container cover 130 and the upper frame 37.
The container cover 130 may include a buffering member 136 arranged under the front end of the container cover 130. The buffering member 136 may be implemented to include an elastic material. The buffering member 136 may be arranged on the bottom of the other side opposite the one side where the pivot shaft member 140 of the container cover 130 is arranged. The buffering member 136 may relieve shocks likely to be caused by a collision between the front end of the container cover 130 and the upper frame 37 when the container cover 130 slams the detergent container 110 shut.
According to embodiments of the present disclosure, a washing machine may have a plurality of washing units, enabling clothes to be washed separately as needed.
According to embodiments of the present disclosure, a washing machine may have a detergent container arranged in an upper portion for storing a detergent to be supplied to a tub, thereby allowing the detergent to be easily supplied to the tub located in a lower portion.
According to embodiments of the present disclosure, a washing machine may have a detergent container for storing a laundry detergent and a detergent container for storing a fabric softener or a bleaching agent arranged separately, thereby preventing the laundry detergent and the fabric softener or the bleaching agent from being mixed and added in together.
According to embodiments of the present disclosure, a washing machine may have a pivot shaft member arranged to be drawn into or out of the container cover, thereby enabling the container cover to be easily detached from or attached to the washing machine.
According to embodiments of the present disclosure, a washing machine may have a recess formed in a portion of a container cover directed to a door arranged on the top, thereby enabling the door to be opened while the container cover holds the detergent container shut.
