Indicated by 1. For example, when a person with a weight of about 65 kg bathes in a bathtub having a height of 60 cm, a width of 70 cm, and a depth of 60 cm, and is boiling at the set water level h0, the water level rises rapidly and the height of about 18 cm rises. That is, h1-h0 = about 18 cm
It shows that it becomes. The output change characteristic diagram of the water level sensor in FIG. 4 shows this with the output of the water level sensor. That is, when a person takes a bath, the output of the water level sensor is V0 → V
It shows that it rises to 1. Here, the case where a person takes a bath will be described in more detail. For example, assume that the microcomputer reads the output of the water level sensor every 1.6 seconds.
Assume a water level sensor output of 1 bit = 2.5 mmH20. When a person takes a bath here, 18 cm is equivalent to 72 bits. If you read the data four times now, 1.6
Seconds x 4 = 6.4 seconds will be required. That is, when the predetermined time is set to 6.4 seconds, for example, the water level rise is 36 bits =
If a person's bath is taken when the water level rises by 9 cm or more, the water level can be detected with less double the safety factor malfunction. On the other hand, when a person takes a bath, the water surface is disturbed, so if you compare the read data as it is as the output of the water level sensor, the water surface disturbance will be the water level disturbance as it is. The more stable the comparison becomes, the better. For example, the data is read every 1.6 seconds, but the data for the fourth time is the value for the third time, the data for the fourth time is added, and the result is divided by 4 and compared as the water level output for the current moving average. Is. When the water level sensor output increase determination means 21 determines that a person has bathed in the above method, a signal is sent from the main body transmission / reception section 15 to the remote control transmission / reception section 16, and the power supply control means 25 restarts the power supply and the power supply is stopped. The display of the display means 24 is turned off, the information is displayed on the driving information display means 23, and the acceptance of the driving instruction from the remote controller 14 is restarted.
