Drum-type washing machine and washing method using the same
Drum-type washing machine 50 is to be washed in the water intake 20 provided at the to configure the circulation channels (22, 26, 27, 28) of the laundry, and water receiving tank 6 which rotates with the rotation of the rotary drum (5) by putting, discharging the wash water from the encased intake 20 to the inside from the discharge port 34, the rotary drum 5, and circulates the wash water sprayed to the laundry. Thus, the wash water contained in the laundry and the rotational speed of the laundry drum (5) and out to be actively circulated, thereby improving the detergency and rinsing performance, and reduced non-uniform rinsing.
AbstractBackground: One of the topics students have difficulties in understanding is electromagnetic induction. Active learning methods instead of traditional learning method may be able to help facilitate students’ understanding such topics more effectively.Purpose: The study investigated the effectiveness of physical models and simulations on students’ understanding daily life applications of electromagnetic induction.Sample: The nine participants in the study were voluntaries from the fourth year of the physics education undergraduate programme.Design and methods: Lessons were designed to enhance students’ conceptual understanding of electromagnetic induction. Researchers developed multiple generator and simple electric motor models. These models and simulations about Faraday’s Law, magnetic field, magnets, generator and radio waves were used in lessons. The data were collected through open-ended questionnaire and semi-structured interview. Open-ended questionnaire was employed in a pre-test and a post...
