HOT WATER REPLENISHING PROCESS CONTROL METHOD IN BATH DEVICE HAVING HOT WATER REPLENISHING FUNCTION WHICH IS ALSO USED FOR DOMESTIC HOT WATER SUPPLY

摘要

PURPOSE:To improve the safety by adopting a control operation in which the hot water replenishing is carried out only when the hot water replenishing switch on the controller is pressed for a plurality of times such as twice, for example, within a certain unit time, and the hot water replenishing is rejected otherwise. CONSTITUTION:When the hot water replenishing switch is turned on after the operation switch is turned on, time is counted from that moment up to a certain time interval (t) which may be 3 seconds, for example. In reality, a soft timer is set up by dividing frequency for the reference clock which actuates the micro computer control section for an automatic bath device, and the time is counted by this soft timer. If the hot water replenishing switch is not turned on in the time interval (t), the hot water replenishing process is not started, and, only when the hot water replenishing switch is again turned on within the time interval (t), the hot water replenishing process is started.
