  • We are studying on the home economics, particularly tools and machines used in household affairs. The object of this paper is to rationalize house cleaning method and to improve the used cleaning tools. We have made a social survey in Korea about the real situation of house cleaning as the first phase of this research. The contents are as follows: 1) The consciousness of housemakers for house cleaning. 2) The methods of house cleaning. 3) The used type of vacuum cleaner. 4) Merits and demerits of vacuum cleaner. 5) Troubles of vacuum cleaner etc. The results has been made in comparison with the same social survey in japan and a small scale different survey in The United States of America by auther in 1979. The results are as follow (in Korea). 1. The almost of housemakers are affirmative in charge of household affairs(95%). 2. In household affairs, only 9% of housemakers dislike cleaning work, but 40% of housemakers do not a cleaning work as a daily periodically. 3. In general household, they do a cleaning work with broom, duster and dust cloth, and then the cleaning work is faily backward in mechanization(The possession of vacuum is 19%). 4. The main dissatisfaction of vacuum cleaner is a noise, and also the difficulty of the cleaning in a corner of the room is shown in high percentage too.

  • Since the emissions composition from the household products have potentially been associated with health risks for building occupants, the chemical composition emitted from the products should be surveyed. The current study identified the emission composition for 42 liquid household products, using a purge-and-trap method. This evaluation was done by classifying the household products into five product classes (deodorizers, household cleaners, color removers, pesticides, and polishes). Nineteen compounds were chosen on the basis of selection criteria. The quality control program for purge-and-trap and analytical systems included tests of laboratory blank Tenax traps and blank water samples, and the determination of calibration equation, measurement precision, method detection limit (MDL), and recovery. The number of chemicals varied according to the product categories, ranging from 4 for the product category of bleaches to 12 for the product categories of air fresheners and nail color removers. For all product categories, the emission composition and concentrations varied broadly according to product. It is noteworthy that most household products emit limonene: 19 of 25 cleaning products; 5 of 6 deodorizers; 1 of 3 pesticides; 3 of 3 color removers; and 4 of 5 polishes. It was suggested that the use of household products sold in Korea could elevate the formation of secondary toxic pollutants in indoor environments, by the reaction of limonene with ozone, which entered indoor environments or might be generated by indoor sources such as electronic air cleaning devices and copying machines.

  • The purpose of this study was to identify household’s level and standard of consumption and their related variables in order to derive some useful implications for developing sustainable lifestyle. Data were collected from 567 household wives living in Seoul and the five Metropolitan cities in Korea. The results showed that most households owned such goods as central heating system, shower and bath, refrigerator, microwave oven, vacuum cleaner, washer. TV video player, personal computer, mobile phone, and car. They thought that most of the goods were necessary for the desired level of living and has a strong aspiration to buy those goods. This implied a tendency of uniformity in need perceptions and consumption patterns among Korean households. However, level and standard of consumption measured in selected living area differed according to age. education family size, household income, occupation, and the size housing, which showed that different approach was needed for developing sustainable lifestyle according to these variables.

  • Cyclone, a type of particle collector widely used in the field of ambient sampling and industrial particulate control, is the principal type of gas-solids separator that uses a centrifugal force. The goal of this study is to design and evaluate the cyclone that can be used for the household vacuum cleaners. A multi cyclone with a 1st cyclone and several 2nd cyclones is designed to improve dust collection efficiency. The dust collection efficiency and the suction power of 1st cyclone are evaluated. And the dust collection efficiency and the suction power of multi cyclone are evaluated according to various sizes of inlet and vortex finder. As a result, a cone shape porous filter has better dust collection efficiency than a cylinder shape porous filter. The dust collection efficiency of a multi cyclone is 3.5% greater than that of a single cyclone.

  • General household vacuum cleaners consist of dust collector, pre filter, motor and exhaust filter, and the filtered clean air is discharged to the atmosphere. By using the CFD methods, we estimated the internal flow in two types of commercial cyclone vacuum cleaners to evaluate the dust collection performance. From the analysis, it was known that the number of revolution had higher values in cyclone cone region. CFD analysis in a specific showed non-uniform velocity distribution at outlet, which results in the deterioration of particle collection performance. In order to improve flow condition, the installation of baffle was proposed and the values of velocity RMS were estimated.

  • No matter how low it might be, noise from home appliances in indoor environment cause displeasure for residents as it is produced nearby. Electronic goods including vacuum cleaner and washing machine generate high frequency noise, which interrupts TV-watching or conversations and cause noises between floors in apartment houses. In particular, refrigerators make constant noise late at night, hampering the study for exams and causing sleeplessness. Korea, despite the government's efforts to promote low-noise goods based on the noise test by corporation, there is a lack of standardization in the test method, test condition and measuring equipments. This is a major reason that lowers the reliability of low-noise products. At present, low-noise home appliances are certified with eco labeling in the nation but, only 7 brands of refrigerators, 4 brands of washing machines and 97 brands of air-conditioners obtained certification as of august, 2011. In addition, none of Kimchi-refrigerator and vacuum cleaner brands were approved as low-noise home appliances. This shows Korea's relatively underdeveloped market for low-noise products, which, in part, is because of the difficulties companies face in being certified with eco labeling as they should satisfy various requirements such as power-saving and eco-friendly design besides low-noise features. As a result, low-noise labeling for home appliances should be established for the revised noise and vibration management law and the study was carried out to establish low-noise labeling system for major noise sources including vacuum cleaner, washing machine, air-conditioner and refrigerator.
