This research is “R & D of a multiple-function bathroom washstand”, it is pinpointing the needs of a bathroom to design a washstand with the multiple functions of dehumidifying and sterilizing, mirror defogging, drying and keeping warm for body, and it is very suitable to apply inside dry-wet separate-type bathroom. Inside a bathroom of general families, it does easily cause mold on the ceiling, wall and towel owing to high humidity. Thus, it results in bad effect for human being’s healthy, causes the rotten surface of ceiling and wall, and affects the sanitation and appearance of a bathroom. People always dry out their hair by an electric blower after hair washing; it does not only waste energy, and also may likely cause shock if the electricity leakage of blower owing to the wet environment of bathroom. Meanwhile, the outlet wind temperature of blower is always over 60℃ and thus makes user uncomfortable. While taking a hot shower or bath in cold days, the high temperature and relative humidity inside a bathroom causes high dew point of air, thus it does easily result in a foggy mirror and make user inconveniently. And it may likely cause a slippery floor because of wet, and it may result in a serious hurt if someone slips down. Inside most present bathrooms, an exhaust fan is always used to draw out the wet air but with no drying effect; a heater or heating fan is used for keeping body warm in cold days but with no dehumidifying function; an electric heater is added in mirror to defog but with shortage of wasting energy and taking risk of shock; towels are used to dry the body but likely affecting germ. In order to solve above problems inside bathroom, a real multiple-function washstand is built and modified after an invention patent. The new creative equipment consists of dehumidifying and heating system inside a washstand; there is a sterilizing device in front of intake airway, and a position adjustable and flexible tube is used as an outtake airway. By remote control to turn on/off the machine, adjust the airflow rate, temperature and flow direction of dehumidified air, the multiple functions of dehumidifying and sterilizing, mirror defogging, drying and keeping warm for body can be achieved inside bathroom. During the R & D process of the new washstand, there are two generations of prototypes are developed. The first-generation prototype is modified after the original invention patent, some shortages have been found after testing and using the washstand. Thus, the modified second-generation prototype is finally built and it owns the potential of mechanized product.
