Filed: 2000-02-02
Abstract: PROBLEM TO BE SOLVED: To solve a problem of not defrost of an evaporator due to a decrease in a cooling efficiency of the evaporator by frosting when frosted according to an integrated time of a compressor and a wasteful power consumption due to a defrosting operation for a predetermined time even by a small frost. SOLUTION: Temperature detectors of two systems are mounted at the evaporator, and the defrosting operation is controlled by judging an actually frosted state according to their temperature difference. The lapse of a predetermined cooling time is confirmed (S2) during the operation of the compressor (S1). When the temperature difference of the two systems is a predetermined value or less or a predetermined defrosting period interval or more by judging the difference (S3), a power supply to the defrosting heater 7 is started (S4). Then, a set temperature or higher of the evaporator is confirmed by a sensor (S5). The power supply to the heater 7 is finished (S6), and the operation is returned to the cooling operation.  Since the defrosting control is conducted by the actually frosted state of the evaporator, wasteful power consumption can be reduced, and a sound indoor temperature management can be conducted.

Excreta are acquired by the urine-sampling unit 12 and is carried to the measurement unit 11, and physical quantity regarding the excreta is measured. When the device has not been used for a long time, the inlet and the inside of an urine-sampling tube 76 and a carrier tube 15 that are the passage paths of urine are blocked by the reproduction of unwanted bacteria and mold, thus preventing urine from being sampled and measurement from being made easily. Therefore, when excreta are to be carried, a small amount of sodium azide or the like with anti-mold effect is mixed into the buffer liquid and is fed into a carrier tube 150. Also, when no measurement is made, the urine- sampling tube is filled with the buffer liquid.
