摘要： PROBLEM TO BE SOLVED: To provide a water heater capable of eliminating various kinds of inconveniences when limitation is released in a case wherethe flow rate of hot water is limited by a user. SOLUTION: The flow rate of hot water is controlled by the normal control mode based on the number control in a normal situation. When the hot water amount limit SW is turned ON, the flow rate of hot water is throttled to the limit hot water amount by the flow rate control by the hot water amount limit mode. Even when the hot water amount limit SW is turned OFF, and the hot water amount limit mode is released, the flow rate is not increased or restored suddenly to the normal flow rate, but allowed to increase step by step. If the presently set temperature of hot water is higher than 50°C, the maximum set flow rate in the high-temperature setting mode is set to the upper limit, and the flow rate is maintained thereafter if the flow rate is increased and restored to the maximum set value.

摘要翻译：要解决的问题：提供一种当用户限制热水的流量的情况下，限制被解除时能够消除各种不便的热水器。
解决方案：正常情况下，基于数字控制，通过正常控制模式控制热水流量。当热水量限制SW被打开时，通过热水量限制模式的流量控制将热水的流量节流到极限热水量。即使当热水量限制SW被关闭并且热水量限制模式被解除时，流量也不会突然升高或恢复到正常流量，而是逐步增加。如果目前设定的热水温度高于50℃，则将高温设定模式中的最大设定流量设定为上限，并且如果流量增加则维持流量恢复到最大设定值。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To adjust and control to an appropriate air supply amount even when combustion air is supplied from one air blowing fan to two combustion parts combustible independently.
SOLUTION: When a closing degree of an air feeding/discharging flow passage on the heating side reaches a predetermined value, a difference between a correction line and an FF line in a relational table 74 between target rotational frequency and fan electric current value (electric current value of A1-C1 when rotational frequency is N1) is added to a read value (detection value) of the fan electric current value of the air blowing fan during individual combustion on the hot water supply side, so as to remove effects on the fan electric current value caused by closing of the heating side. Based on the fan electric current value after the addition, when the fan electric current value is lower than a dead zone, the rotational frequency of the air blowing fan is corrected and increased. When the fan electric current value is higher than the dead zone, the rotational frequency of the air blowing fan is continued without correction.

摘要翻译：要解决的问题：即使当从一个送风风扇向独立燃烧的两个燃烧部分供给燃烧空气时，也可以调节和控制适当的空气供给量。解决方案：当加热侧的空气供给/排出流路的闭合程度达到预定值时，目标转速和风扇电流值之间的关系表74中的校正线与FF线之间的差（旋转频率为N1时的A1-C1的电流值）与在热水供给侧的单独燃烧时的送风风扇的风扇电流值的读取值（检测值）相加，从而去除效果对由加热侧的关闭引起的风扇电流值的影响。根据加法后的风扇电流值，当风扇电流值低于死区时，对吹风风扇的转速进行校正和提高。当风扇电流值高于死区时，继续吹风风扇的转速而无需校正。版权所有（C）2009，JPO＆INPIT
