Abstract: The case accommodates the washing treatment agent to be dispensed to a washing machine tank of the washing machine. The case includes a main body portion and a water supply portion. The main body portion includes a bottom portion that receives the washing treatment agent. The water supply portion supplies water to the main body portion. The bottom portion includes an upper surface including one end portion, the one end portion being positioned above another end portion in a first direction. The upper surface includes an inclined portion having a first gradient varying in the first direction, the first gradient indicating a ratio of a distance in a vertical direction to a distance in the first direction.

Abstract: A filter member is detachably mounted in a filter case formed with an inflow port through which washing water flows in and an outflow port through which the washing water flows out. The filter member includes a rib-shaped portion partitioning through holes adjacent to each other. At least one of the through holes is inclined from an inner peripheral surface of the filter member.

Abstract: A larger amount of light generated by a light source is emitted to the interior of an accommodation chamber. A lighting device provided on a side wall of an accommodation chamber of a refrigerator includes a light source that generates light, and a cover including a light incident portion on which the light generated by the light source is incident. The cover includes a light exit portion that includes a protrusion formed at a front surface facing the interior of a storage compartment, and causes light to exit to the interior of the storage compartment, and a light reflection diffusion portion that is formed on the back side of the light exit portion at a back surface facing the light source side, includes a plurality of recesses each having an inner peripheral surface, and directs light toward the protrusion.

Abstract: A mill includes a first mill having a first grinding region, a second mill having a second grinding region opposed to the first grinding region and provided to be rotatable relatively to the first mill, and a heat radiation mechanism which is provided in at least one of the first mill and the second mill and radiates friction heat generated as a result of rotation of the first mill and the second mill relative to each other, and the heat radiation mechanism is provided in a portion except for the first grinding region and the second grinding region.

Abstract: In a mill having a first mill provided with a first grinding surface and a second mill provided with a second grinding surface, the first grinding surface includes a first groove in a curved shape which extends from a side of a center of rotation C toward an outer circumference, the second grinding surface includes a second groove in a curved shape which extends from the side of the center of rotation C toward the outer circumference, and while the first grinding surface and the second grinding surface are superimposed on each other, the first groove and the second groove are not superimposed on each other and an angle (an angle of intersection) ? at which the first groove and the second groove intersect with each other is 10°???50°.

Abstract: An agitation blade for agitating a liquid includes a cylindrical core having a central axis of rotation and a plurality of blade portions provided on a side of a first surface of a rotation portion, and the plurality of blade portions are provided to surround the central axis of rotation and provided to be rotated with respect to a center of rotation of the central axis of rotation.

Abstract: An agitation unit includes an agitation tank to which a liquid is supplied and an agitation member which agitates the liquid supplied to the agitation tank. The agitation tank has an area of opening in a horizontal direction decreasing in a downward direction.

Abstract: A beverage preparation apparatus prepares a beverage with a liquid and powders, and includes an agitation unit including an agitation blade which agitates the liquid and the powders and an agitation tank which accommodates the agitation blade, an agitation blade drive portion which rotationally drives the agitation blade, and a control portion which controls the agitation blade drive portion. The agitation blade has a central axis of rotation and is provided with a plurality of blade portions surrounding the central axis of rotation. The control portion controls the agitation blade drive portion so as to switch between forward rotation and reverse rotation of the agitation blade.

Abstract: In a mill having a first mill provided with a first grinding surface and a second mill provided with a second grinding surface, the first grinding surface includes a first groove in a curved shape which extends from a side of a center of rotation C toward an outer circumference, the second grinding surface includes a second groove in a curved shape which extends from the side of the center of rotation C toward the outer circumference, and while the first grinding surface and the second grinding surface are superimposed on each other, the first groove and the second groove are not superimposed on each other and an angle (an angle of intersection) ? at which the first groove and the second groove intersect with each other is 10°???50°.
