である。FIG. 3 is an explanatory view showing the structure of the connection type water heater. In this figure, 100 and 200 are, for example, 3.5 to 1, respectively.
It is a water heater for bathrooms and kitchens with a hot water supply capacity up to No. 6, and therefore the burners 1A and 1B have solenoid valves 2A, 2B,
The gas is configured to be supplied via the proportional valves 3A and 3B, and is controlled by the microcomputer control unit described later. 4A and 4B are heat exchangers, and 5A and 5B are fans. Further, water amount sensors 6A, 6B and water temperature variable type water governors 7A, 7B are attached to the water supply side of the water heater, and the water supply temperature is detected by a thermistor 8. Further, the hot water supply pipes of the hot water supply device 100 and the hot water supply device 200 are provided with thermistors 9A and 9B, respectively, to detect the hot water discharge temperature. The tap pipe 10 of the water heater 100 for the bathroom is connected to the hot water tap (or mixing tap) 11 in the bathroom,
The hot water supply pipe of the water heater 200 for the kitchen is connected with the water switching valve 12 to the hot water discharge pipe 10 of the water heater for the bathroom.
The hot water supply pipe is connected to a kitchen side hot water tap 15 through a hot and cold water mixing valve 14 whose temperature is set by a gear motor 13. 16 is a thermistor that detects the hot water temperature reaching the hot water tap 11, 17 is a running water switch that is turned on when the kitchen hot water tap is opened, 18A is a remote controller on the bathroom side, 18B is a remote controller on the kitchen side, 19 is a microcomputer control unit, and each thermistor The temperature of the hot water and the amount of hot water set in the remote controllers 18A and 18B are controlled based on signals from the water flow rate sensor, the water flow sensor, and the like. The water temperature variable type water governors 7A and 7B have a constant temperature, for example, 60 ° C. under any water temperature condition without squeezing the hot water taps 11 and 15.
In order to obtain the hot water, the water temperature is controlled to about 7 / min at a water temperature of 5 ° C. and about 12 / min at a water temperature of 25 ° C., for example.
上記の如く構成した連結式給湯器は、出湯量が少なくて
低号数の場合には、水切替弁12を閉じて給湯器100,200
の何れか一方のみを運転して給湯し、浴槽に対する湯張
り時のような高号数の場合には、双方の給湯器100,200
を運転し、かくして例えば約3.5号から32号までの給湯
を行なうことができる。In the connection type water heater configured as described above, when the amount of discharged hot water is small and the number of hot water is low, the water switching valve 12 is closed and the water heater 100, 200
In case of a high number such as when filling the bathtub with hot water, only one of the water heaters 100,200
Can be operated, and thus hot water can be supplied, for example, from No. 3.5 to No. 32.
ところで、上記の如き従来の連結式給湯器は、台所側の

出湯温度がリモコンの制定温度よりも高い場合にはミキ
シング後の湯温がリモコンの設定温度になるように熱交
換器4Bからの湯量を絞ると共にそれに応じて給水量を増
加させるように構成されている。By the way, in the conventional connection type water heater as described above, the mixing valve 14 takes the set temperature position of the remote controller regardless of the opening / closing of the hot water tap on the kitchen side and the flow rate of the heat exchanger 4B. That is, the mixing valve 14 compares the hot water temperature from the heat exchanger 4B with the set temperature of the remote controller,
When the hot water outlet temperature is higher than the established temperature of the remote controller, it is configured to throttle the amount of hot water from the heat exchanger 4B so that the hot water temperature after mixing becomes the set temperature of the remote controller and increase the amount of supplied water accordingly. There is.
このため、例えば、設定温度36℃、水温20℃、4B側熱交
換器の流量３/minの場合 には、要求号数が器具の最低号数（3.5号）を下回るの

同様の動作をくり返して出湯温のハンチング現象を来す
という問題がある。Therefore, for example, when the set temperature is 36 ℃, the water temperature is 20 ℃, and the flow rate of the 4B side heat exchanger is 3 / min Since the required number of instruments is less than the minimum number of instruments (3.5), the hot water temperature from the heat exchanger 4B, that is, the mixing valve
The temperature of the hot water entering 14 becomes equal to or higher than the set temperature, so that the mixing valve 14 acts to reduce the amount of hot water entering from the heat exchanger 4B. Thus, when the amount of hot water is reduced, the hot water temperature on the heat exchanger side further rises, As a result, the mixing valve 14 further reduces the amount of hot water, and while repeating this operation, the flow rate becomes below the combustion OFF flow rate and the burner is extinguished. When it is digested in this way, water comes out from the heat exchanger 4B, and the mixing valve 14 operates to open the hot water side this time, and when the amount of water exceeds the combustion ON flow rate, it ignites again, and again the same operation as described above. There is a problem that the hunting phenomenon of the hot water temperature occurs repeatedly.

る。According to the present invention, as described above, when the required number of kitchen appliances is smaller than the minimum number of appliances, the mixing valve is fully opened and hot water is not mixed. When the required number is larger than the minimum number of the appliance, hot water can be mixed as the set temperature of the remote controller to obtain hot water having a desired temperature.

量である。When the power switch is turned on and then the operation switch of the remote control is turned on, the mixing valve 14 is fully opened on the hot water side (heat exchanger side). When the hot water tap 15 on the kitchen side is opened in this state, the water flow switch 17 is turned on, and when the water amount sensor 6B detects that the flow rate has reached the flow rate necessary for operating the appliance,

に設定された温度位置にする。Next, the flow rate α calculated as described above is compared with the flow rate FS 2 flowing through the heat exchanger 4B, and only when the flow rate FS 2 is larger than α, the set temperature of the remote controller is read to read the mixing valve.
14 is the set temperature position of the remote control, and conversely, the flow rate FS 2 is α
When it is smaller, it is determined whether or not the other heat exchanger 4A side is burning, and when it is not burning, the flow rate detection by the water amount sensor 6B and the water temperature detection by the thermistor 8 are continued with the mixing valve 14 kept at the fully open position on the hot water side. That is, in the present invention, the single use of the heat exchanger 4B, when the required number is smaller than the minimum number of equipment, the mixing valve 14 is fully opened on the hot water side, and the required number is larger than the minimum number of equipment.
