摘要:: 研究了老人洗浴时的人体适温曲线,并设计老人助浴装置的水温控制管路。通过实验,获取人体洗浴最佳体感温升数据,采用最小二乘法,拟合出人体洗浴适温曲线;根据热力学第一定律,考虑水流速率、热量损失、水比热容、冷热混合水温以及人体最佳体感温升数据等因素,建立热水阀门开度控制模型,结合人体适温曲线,实现热水阀门控制曲线求解;设计水温控制管路,并应用于老人助浴装置样机中。测试结果表明,水温实际变化过程与人体适温控制曲线基本一致,符合人体适温规律,可有效提高老人洗浴舒适性。

Abstract:: This paper studied the appropriate temperature curve of the human body when the elderly took a bath , and designed the water temperature control pipeline of the bath aid device for the elderly. Through the experiment ,the data of the best body temperature rise for human body bath was obtained , and the optimal temperature curve for human body bath was fitted by the least square method.According to the first law of thermodynamics and considering the water flow rate , heat loss , specific heat capacity of water , mixed cold and hot water temperature and the optimal body temperature rise data of human body , the control model of hot water valve opening was established , and the control curve of hot water valve was solved by combining the appropriate temperature curve of human body.The water temperature control pipeline was designed and applied in the prototype of bath aid device for the elderly.The test results show that the actual change process of water temperature is basically consistent with the control curve of human body’s appropriate temperature , which accords with the law?of?human?body’s?appropriate?temperature , and?effectively?improves?the?bathing?comfort?of?the elderly.
