　なお、低温側設定温度である３６℃から高温側設定温度である３８℃に到達するまでの設定運転時到達時間Ｔｙ２についても、通常運転モードにおける同じ温度変化による通常運転時到達時間より長く設定している。
　このように、温冷運転モードにおける設定運転時到達時間Ｔｙ１を通常運転モードにおける通常運転時到達時間Ｔｘ１よりも長くすることで、温冷運転モードにおける湯温変化が緩やかになり、使用者に急激な温度変化による不快感を与えず、通常運転モードでは、使用者の操作に応じて素早く湯の温度を変更できる。 In this embodiment, the high temperature setting temperature is the temperature of the hot water being used in normal operation mode, and the low temperature setting temperature is 2°C lower than the high temperature setting temperature. and the set temperature on the low temperature side can be set in advance. Also, the time at the high temperature setting temperature and the time at the low temperature setting temperature can be set in advance.
FIG. 4 shows the case where the temperature of the hot water being used in the normal operation mode is 38°C, and in this case the set temperature on the low temperature side is set to 36°C.
Ty1 indicates the time it takes for the temperature of the hot water to reach the set temperature of 38° C. on the high temperature side and the set temperature on the low temperature side of 36° C. during the set operation. The set operation arrival time Ty1 is set longer than the normal operation arrival time Tx1 for the same temperature change in the normal operation mode.
Note that the set operation arrival time Ty2 from the low temperature set temperature of 36°C to the high temperature set temperature of 38°C is also set longer than the normal operation arrival time due to the same temperature change in the normal operation mode. ing.
In this way, by making the set operation arrival time Ty1 in the hot/cold operation mode longer than the normal operation arrival time Tx1 in the normal operation mode, the change in hot water temperature in the hot/cold operation mode is moderated, and the user feels a sudden change. In the normal operation mode, the temperature of the hot water can be changed quickly according to the user's operation without causing discomfort due to sudden temperature changes.
　図５はクールダウン運転モードにおける操作部及び表示部を示す概略構成図及び温度変化図である。
　第２モード選択内容として、設定運転モードがクールダウン運転モードを選択し、加圧運転モードが停止を選択している場合には、第２モード選択部１５ｂを動作指示することで、図５（ａ）に示すように、第１表示部２１では通常運転モードで使用中の湯の温度が３８℃であることを表示し、第２表示部２２ではクールダウン運転モード（Cool Down）であることを「Cool」で表示し、第３表示部２３では加圧運転モードが停止であることを「Pump Off」で表示し、第５表示部２５では第２モード選択内容であることを「２」で表示する。
　図５（ｂ）に示すように、クールダウン運転モードでは、通常運転モードで使用中の湯の温度から所定温度低下させる。 FIG. 5 is a schematic configuration diagram and a temperature change diagram showing an operation unit and a display unit in the cool-down operation mode.
As the second mode selection content, when the set operation mode selects the cool-down operation mode and the pressurization operation mode selects stop, by instructing the operation of the second mode selection unit 15b, FIG. As shown in a), the first display unit 21 displays that the temperature of the hot water being used is 38° C. in the normal operation mode, and the second display unit 22 displays that it is in the cool down operation mode (Cool Down). is displayed as "Cool", the third display section 23 displays that the pressurizing operation mode is stopped as "Pump Off", and the fifth display section 25 displays "2" as the second mode selection content. to display.
As shown in FIG. 5(b), in the cool-down operation mode, the temperature of the hot water being used in the normal operation mode is lowered by a predetermined temperature.
　本実施例では、クールダウン運転モードにおいて低下させる所定温度を2℃としている。従って、使用中の湯の温度が３８℃で所定温度が２℃であるため、クールダウン目標湯温は３６℃である。
　Ｔｙ１は、使用中の湯の温度である３８℃からクールダウン目標湯温である３６℃に到達するまでの設定運転時到達時間を示している。設定運転時到達時間Ｔｙ１は、通常運転モードにおける同じ温度変化による通常運転時到達時間Ｔｘ１より長く設定している。
　このように、クールダウン運転モードにおける設定運転時到達時間Ｔｙ１を通常運転モードにおける通常運転時到達時間Ｔｘ１よりも長くすることで、クールダウン運転モードにおける湯温変化が緩やかになり、使用者に急激な温度変化による不快感を与えず、通常運転モードでは、使用者の操作に応じて素早く湯の温度を変更できる。 In this embodiment, the predetermined temperature to be lowered in the cool-down operation mode is 2°C. Therefore, since the temperature of hot water during use is 38°C and the predetermined temperature is 2°C, the target hot water temperature for cooling down is 36°C.
Ty1 indicates the set operating time from 38° C., which is the temperature of the hot water in use, to 36° C., which is the cool-down target hot water temperature. The set operation arrival time Ty1 is set longer than the normal operation arrival time Tx1 for the same temperature change in the normal operation mode.
Thus, by making the set operation arrival time Ty1 in the cool-down operation mode longer than the normal operation arrival time Tx1 in the normal operation mode, the change in the hot water temperature in the cool-down operation mode becomes gentle, and the user feels a sudden change. In the normal operation mode, the temperature of the hot water can be changed quickly according to the user's operation without causing discomfort due to sudden temperature changes.

　図６（ｂ）に示すように、ウオームアップ運転モードでは、通常運転モードで使用中の湯の温度から所定温度上昇させる。 FIG. 6 is a schematic configuration diagram and a temperature change diagram showing the operating section and the display section in the warm-up operation mode.
As the third mode selection content, when the set operation mode selects the warm-up operation mode and the pressurization operation mode selects stop, by instructing the operation of the third mode selection unit 15c, FIG. As shown in a), the second display unit 22 displays "Hot" to indicate that the warm-up operation mode (Warm up), and the third display unit 23 displays "Pump" to indicate that the pressurization operation mode is stopped. "Off", and the first display section 21 indicates that the temperature of the hot water being used in the normal operation mode is 38°C.
As shown in FIG. 6B, in the warm-up operation mode, the temperature of the hot water being used in the normal operation mode is raised by a predetermined temperature.
　本実施例では、ウオームアップ運転モードにおいて上昇させる所定温度を2℃としている。従って、使用中の湯の温度が３８℃で所定温度が2℃であるため、ウオームアップ目標湯温は４０℃である。
　Ｔｙ３は、使用中の湯の温度である３８℃からウオームアップ目標湯温である４０℃に到達するまでの設定運転時到達時間を示している。設定運転時到達時間Ｔｙ３は、通常運転モードにおける同じ温度変化による通常運転時到達時間Ｔｘ３より長く設定している。
　このように、ウオームアップ運転モードにおける設定運転時到達時間Ｔｙ３を通常運転モードにおける通常運転時到達時間Ｔｘ３よりも長くすることで、ウオームアップ運転モードにおける湯温変化が緩やかになり、使用者に急激な温度変化による不快感を与えず、通常運転モードでは、使用者の操作に応じて素早く湯の温度を変更できる。 In this embodiment, the predetermined temperature to be raised in the warm-up operation mode is 2°C. Therefore, since the temperature of the hot water in use is 38°C and the predetermined temperature is 2°C, the warm-up target hot water temperature is 40°C.
Ty3 indicates the set operating time from 38° C., which is the temperature of hot water in use, to 40° C., which is the warm-up target hot water temperature. The set operation arrival time Ty3 is set longer than the normal operation arrival time Tx3 for the same temperature change in the normal operation mode.
In this way, by making the set operation arrival time Ty3 in the warm-up operation mode longer than the normal operation arrival time Tx3 in the normal operation mode, the hot water temperature change in the warm-up operation mode becomes gradual, and the user feels a sudden change. In the normal operation mode, the temperature of the hot water can be changed quickly according to the user's operation without causing discomfort due to sudden temperature changes.
