Document Type and Number:
Japanese Patent JP2020153896
Kind Code:
A
Abstract:
To provide a toilet seat device capable of accurately calculating an evacuation amount without a floor weight meter, and performing daily evacuation management.SOLUTION: A toilet seat device comprises: a toilet seat 14 on which a user is seated; a plurality of load sensors 18 for detecting a seating load value acting on the toilet seat; and an arithmetic device 20 for calculating the plurality of seating load values detected by these sensors for calculating an evacuation amount of the user. The arithmetic device acquires a plurality of seating load values which are detected by the plurality of load sensors simultaneously when the user is seated on the toilet seat, at different timings, calculates a ratio by combination of the seating load values detected by a plurality of prescribed load sensors out of the plurality of seating load values detected simultaneously, for different timing, for estimating a posture of the user, then estimates that the user is at an equal posture when these values are equal, and estimates that the user evacuated the bowels according to a change amount of a total value of the seating load values at the ratio for unit time, and then estimates the evacuation amount according to a difference of the total value of the seating load values before and after evacuation.SELECTED DRAWING: Figure 4
