Abstract
There is generalized to use some carpet as the finishing material of the floor in Japanese houses except one or two rooms of the traditional Tatami Zashiki. Consequently the method of cleaning work has been changed to using by the various vacuum cleaner from sweeping by the broom. But we have found no research in the world which took an accurate measurement of the human energy expenditure of cleaning work by the vacuum cleaner.
The purpose of our study is to make evident the energy expenditure of cleaning work by three kinds of the vacuum cleaner, the cylinder type, the shoulder type and the upright type with the beater, in some room where the floor is Tatami, the smoothly hard one, or finished with four kinds of carpet, and in which the amount of furnitures is varied. As the result the character of each type of the vacuum cleaner may be clear on the energy expenditure and the most suitable type of it may be expected to find in the narrow room with much furnitures in Japanese houses.
Then many kinds of experimental value are obtained on the energy expenditure of cleaning work with given conditions, and shown to Tables 4-11. As the result, it is concluded that the cylinder type cleaner, which is generally used in Japan, is appropriate to cleaning work on the energy expenditure in comparison with the other type cleaner.
In this paper it may be worthy of note that the accurate consequence has been obtained to measure the energy expenditure of cleaning work of only a few subjects by the successive automatic respiration analyzer and to analyze many of measuring values statistically.
