  • Publication number: 20110265889
    Abstract: An automatic urine collecting device (1) is provided with: a main tank (20) for collecting and containing urine received by a urine receiver; a body case for supporting the main tank (20); a suction pump (53) for sucking the urine, which is received by the urine receiver, into the main tank (20) through a urine flow path by sucking air within the main tank through an airflow path; a urine sensor for detecting urine; and a control device for outputting a control command on the basis of the result of the detection by the urine sensor. The urine sensor is provided with a main-tank infrared sensor (S31) capable of detecting bubbles present in the upper part of the urine contained in the main tank (20). The configuration enhances the reliability of the suction pump.

  • Patent number: 5477984
    Abstract: A disinfector accommodates a jetting nozzle and a hand detecting sensor disposed alongside of the jetting nozzle in a main body thereof. The jetting direction of the jetting nozzle coincides with the light emission direction of the hand detecting sensor. The jetting nozzle and the hand detecting sensor can be pivotally moved in unison. A malfunction which may occur due to the difference in the configurations of the bowl of the washstand and the kind of the material thereof can be solved by merely altering the light emission direction of the hand detecting sensor. Because the jetting direction of the jetting nozzle and the light emission direction of the hand detecting sensor are always coincident with each other, a user can use the jetting apparatus conveniently without feeling discomfort.
