The door-lock switch is one of the most important part in the front-load washer. As an safety system, it keeps the door locked while the front-load washer or the dish washer is working and generating heat and spin. The door of front-load washer needs the emotionality as well as the safety because the consumers always get feels when using it. In this paper, We study about emotional factors in the door of front-load washer and analyze the difference of emotionality as the structure of the door-lock switch changed. For this, we analyze the force graph by using the software and the jig which can measure the force while the door is opened or closed.

according to rapid development in current industrial technologies, technology alone is no longer the only competitive factor among the manufacture companies. The value of innovation in product design has increased important attention to more consumers. This paper demonstrates the methodology of design strategy through the case studies of successful washing machine manufacturers on the China's Market. By the so called 4PS comparison of Haier washing machines with those of Siemens and Little Swan, this paper shows the difference of Haier's design strategy with other competitors, and offers a methodology of systematically analyzing strategic design and successfully develops a framework of design strategy.

세탁기의 탈수 행정 시, 터브 내 세탁포가 고르게 분포되어 있지 않으면 세탁포가 한쪽방향으로 쏠려 터브가 크게 흔들리는 언밸런스 현상이 발생하게 된다. 이런 언밸런스 현상은 전동기 및 세탁기에 기구적인 손상을 발생시키기 때문에 즉시 감지하여 탈수 행정을 중지시키도록 해야 한다. 본 논문에서는, 세탁기의 언밸런스 현상이 발생 시 나타나는 전동기의 기계적인 주파수를 갖는 전류 리플을 가변 밴드패스 필터를 이용하여 측정한다. 측정된 전류 리플을 바탕으로 언밸런스 현상을 감지하는 알고리즘을 제안한다.

The variation of a load characteristic in the motor drive is one of the most important consideration. Because the current flowing into the motor generally varies according to the load variation, it needs to design the motor drive circuit properly in accordance with the load variation. However, the load variation of the drum washing machine is irregular and large due to the water flow and reverse load torque. Therefore, to design the motor drive circuit considering this load pattern, simulation results shows the load pattern modeling of the drum washing machine based on the physical analysis in this paper.

Launched by Samsung in 2003, nano-silver washing machines were a representative application of nanotechnology in commercial products until the US Environment Protection Agency (EPA) decided to regulate companies that produce nano-silver products in 2006. A year later, however, the EPA reclassified the washing machines not as an application of nanotechnology but as an ion-generating machine. As shown by the EPA's equivocation on this issue, establishing a category for nano-silver material should be considered in the procedure of risk assessment and regulation. This paper analyzes the controversy over Samsung's nano-silver washing machines more in detail to study how the demarcation between silver ion and nano-silver can vary according to the risk perception of nanotechnology. In Korea and the US, the boundary between silver ion and nano-silver was malleable and mobilzed depending on the contexts. Based on an analysis of the recent history of nano-silver washing machines, this paper explores the influence of risk perception over the ontological perspectives on a certain material.
