Abstract: A seed package includes a seed accommodation member replaceably mounted in a cultivation space of a plant cultivation apparatus and formed of a material capable of absorbing moisture while accommodating the cultivation seeds therein; a container forming a space for accommodating the seed accommodation member; a container cover shielding the open upper surface of the container; and a shielding member provided inside the container and made of a structure through which water can pass, the container including a bottom surface and a circumferential surface extending upward along the circumference of the bottom surface, the bottom surface including a recessed portion and a water inlet spaced apart from the recessed portion and opened to allow water to flow into the container, and the water inlet and the shielding member being disposed so that at least a portion thereof overlaps.

Abstract: In a control method of a washing machine, a washing operation is performed through a heating washing process for a first set time and is performed through a non-heating washing process for a residual time, and, if the heating washing process is started, the rotation of a driving motor is weakly controlled until a washing water temperature reaches a primary target temperature, and is strongly controlled until the washing water temperature reaches a secondary target temperature after the washing water temperature reaches the primary target temperature, so that the washing water temperature is relatively gradually increased.

Abstract: In a control method of a washing machine, a primary nephelometric turbidity unit (NTU) of washing water is sensed before a washing course is started in a washing cycle, a second NTU is sensed based on the primary NTU, and a washing time, an amount of washing agent, and/or a number of times of rinsing are varied based on a difference value between the primary NTU and the secondary NTU, thereby improving washing performance and washing efficiency.

Abstract: A washing method includes (a) continuously rotating a drum in one direction at a first speed such that laundry is lifted to a predetermined height and then falls, (b) accelerating the drum to rotate the drum at a second speed such that the laundry is moved in a state in which at least some of the laundry clings to the drum, and (c) spraying wash water into the drum during rotation of the drum at the second speed.

Abstract: A washing machine that performs a washing course by heating wash water and a control method thereof are provided. The method includes supplying wash water up to a wash water level for generation of steam such that a portion of laundry received in an inner tub is saturated by the wash water. The wash water level may be above a bottom surface of the inner tub and below a wash water level for main washing. The method then includes heating the wash water to a first set temperature and driving a washing heater to generate steam from the wash water, and supplying the generated steam to the inner tub, and then supplying the wash water up to the wash water level for main washing, and driving the washing heater again to heat the wash water to a second set temperature, the second set temperature being lower than the first set temperature.
