て、「開」「閉」ができる。2. Description of the Related Art Conventionally, this type of bath kettle with a water heater has a configuration as shown in FIG. 2, for example. In detail, reference numeral 1 denotes a bath kettle with a water heater, which includes a heat exchanger 2 for hot water supply and a heat exchanger 18 for flushing a bath, which are used for supplying hot water to a kitchen or a shower and flushing a bath, respectively. . First, the water supply side will be described. When water is introduced into the bathtub 1 with the water heater by the water supply pipe 3 connected to the water pipe, the water is branched and one is guided to the water amount sensor 4 and the hot water supply heat exchanger 2, and the other is to the bypass valve 26. After being guided, the hot water heated by the hot water supply heat exchanger 2 joins the hot water and flows through the hot water supply pipe 6 to reach the water quantity proportional valve 5 provided at the tip thereof. When the hot water exits the water quantity proportional valve 5, the hot water pipes B and 8 connected to the electromagnetic valve 7 for automatic hot water supply and the hot water pipes A and 10 that are guided to the hot water tap 9 installed in the kitchen or the like.
At a branch portion 11. An electromagnetic valve 7 for automatic hot water supply is provided at the end of the hot water supply pipe B.8, passes through a first check valve 27, passes through a vacuum breaker 28, passes through a second check valve 29, and passes to a bath circuit branch section 36. The two-way valve 31 is connected to one side. The two-way valve 31 has a ball valve (not shown) inside, and the ball valve is rotated by a motor 32. The two-way valve 31 can be "opened" and "closed" by the rotation of the ball valve.

を検出する風呂往き管閉塞判定部38が設けてある。Reference numeral 34 denotes a controller of the bathtub 1 with a water heater, which has an automatic hot water supply sequence described later, and executes the sequence together with the remote controller 32. Reference numeral 35 denotes an automatic hot water supply switch for automatically controlling the bath 1 with a water heater. 37 is an operation switch. 38 is a power outlet. 3 and 4 show the automatic hot water supply sequence.
Explanation will be made based on FIG. 5, FIG. 5, and FIG. Here, when both the water amount sensor 4 and the flow switch 30 are turned “ON” and it is confirmed that water is flowing, the process proceeds to the next sequence. But here if the automatic hot water supply solenoid valve 7 is "open" since the amount of water sensor 4 and flow switch 30 within the predetermined time T 1 (e.g. 10 seconds) with no "ON" remote control 32 (eg a bath remote controller) The error indication 33 is displayed by a numeral (for example, 53) or the like, and the automatic hot-water supply electromagnetic valve 7 is closed to detect an abnormality when the bath access pipe 19 is blocked by freezing. A blockage judging section 38 is provided.

ンプは「OFF」（停止）のままである。When it is confirmed that there is no blockage of the bath going pipe 19 and the like, the two-way valve 31 is opened, and the bath is returned by the bath returning pipe 22 and the bath going pipe 19 for a predetermined time T 2 (for example, 30 seconds). At this time,
The circulating pump 17 provided in the bath return pipe 22 is automatically filled with water, and the work of priming the conventional circulating pump is automatically performed. A water level sensor 23 is provided between the circulation pump 17 and the bath adapter 20. At this time, the circulation pump remains “OFF” (stopped).

サー23により、浴槽21内の水位検出ができる。Next, after the circulation pump 17 is turned "OFF", the automatic hot water supply electromagnetic valve 7 is turned "ON", and a predetermined time T 4 (for example, 30 seconds)
The hot water is automatically poured in both the bath going pipe 19 and the bath returning pipe 22. At this time, the priming pump 17 is automatically primed again. (At this time, the circulating pump 17 is still “OFF” (stopped).) Next, the two-way valve 31 is closed, and the transfer is performed only from the bath pipe 19. At this time, since the two-way valve 31 is closed, the water level in the bathtub 21 can be detected by the water level sensor 23.

所に来ると水位センサー23の出力が上昇しはじめるの
で、たとえば10ビット（水位で約2.5cm）上昇した所を
変曲点とすると浴槽水変曲点判定部40を設けている。When the water level in the bathtub 21 comes to the bath return pipe 22 of the bath adapter 20, the output of the water level sensor 23 starts to rise. For example, if the place where 10 bits (about 2.5 cm in water level) rises is set as an inflection point, the bathtub A water inflection point determination unit 40 is provided.

上げる。Thereafter, the automatic hot-water supply electromagnetic valve 7 is closed, and then the circulating pump 17 is turned on to check the circulating water so that the air in the pipe is completely removed. At this time, the flow switch 30 is turned “ON”. Thereafter, while the two-way valve 31 in the "closed", the circulation pump 17 in the "OFF", again, the automatic hot water supply solenoid valve 7 and "ON", after a predetermined time T 7 (e.g. 20 seconds) Bathtub water level reference point determination unit 41 with water level as reference value
Is provided. Thereafter, the water is transported by the bath outflow pipe 19 to the set water level. When the set water level is reached, the circulating pump 17 is opened while the automatic hot water supply electromagnetic valve 7 is closed and the two-way valve 31 is opened.
To “ON” and check the circulating water. If the bath water is lower than the set temperature, remove the bath water (bath heat exchanger 18).
→ bath going pipe 19 → bathtub 21 → bath returning pipe 22 → water level sensor
23 → circulation pump 17 → two-way valve 31 → bath heat exchanger 18 and circulate bath water to heat. ) And boil to the set temperature.

んだ量は次式で示される。Here, the amount dropped into the bathtub from the water level reference point to the set water level is integrated by the water amount sensor 4. In this embodiment, assuming that the flow rate flowing through the bypass valve 26 and the flow rate flowing through the water amount sensor are set to 4: 6, the amount dropped into the bathtub is expressed by the following equation.
