る構成となっている。FIG. 1 is a block diagram showing an example of the main functional parts of the hot water supply control device of the present invention. In the automatic hot water supply bath pot, when the automatic operation switch of the hot water supply remote control 3 is turned on, the controller 4
The upstream side 5a of the circulation pipe 5 of the reheating device 40
The hot water supply device 30 is operated by a two-pipe hot water supply using the downstream side 5b, etc.
Hot water is automatically supplied to the bathtub 1 by opening the automatic hot water tap V8, and the hot water supply is automatically stopped when the set water level b is reached.

たとき、コントローラー４にその旨が入力される。[0015] C is an initial circulation means, which is used during the first automatic hot water supply;
Alternatively, when detecting the water level at regular intervals, by closing the switching solenoid valve 7 for a fixed period of time, hot water is supplied only from one pipe from the downstream side 5b of the circulation pipe 5, and the pressure is detected from the upstream side 5a. Use as a pipe. Therefore, when the water level detecting means B detects the initial reference water level a at the bath adapter position such that the bath adapter 6 provided at the lower part of one side of the bathtub 1 is submerged, this is inputted to the controller 4.

In response to a command from the controller 4, the automatic hot water tap V8 is closed to temporarily stop hot water supply, and the two-pipe hot water supply path of the circulation pipe 5 is switched to the circulation flow path by opening the flow path switching device (switching solenoid valve) 7. At the same time, the circulation pump P provided in the circulation pipe 5 is started to circulate the hot water at the initial reference water level a in the bathtub 1 through the circulation pipe 5 from the front stream side 5a to the rear stream side 5b, so that the reference water level is The structure is such that the air stagnant in the circulation pipe 5, which is the detection part, is expelled to maintain a stable water level.

きる構成となしている。In the circulation by the initial circulation means C, if the circulation detection means E, for example, the circulation water flow switch S provided in the circulation pipe 5 has been ON for a predetermined time or more, it is determined that the initial reference water level a exists, and then , by stopping the circulation pump P, it is possible to circulate for a predetermined period of time.
【００１８】一方、所定時間以上循環水流スイッチＳが

うになしている。On the other hand, if the circulating water flow switch S is not turned on for a predetermined period of time or more, the system returns to the initial automatic hot water supply control again.
【００１９】なお、前記初期基準水位ａはその記憶手段
Ｆに記憶させ、常時一定のバスアダプター等の位置の初
期基準水位ａが得られるようにしている。The initial reference water level a is stored in the storage means F so that a constant initial reference water level a for the position of the bus adapter etc. can be obtained at all times.

イコン制御等によって行うものである。D is a water filling water level control means for the bathtub 1, which calculates the water filling level based on the initial reference water level detection value and the water level detection value after circulation by the initial circulation means C, and calculates the set water level b from the result. The configuration is such that the determination is made by, for example, microcomputer control.
【００２１】前記湯張り水位を設定する基準水位として

値を採用するのがよい。[0021] As the reference water level for setting the water filling level, it is preferable to compare the water level detection values before and after circulation and use the lower detection value.
【００２２】なお、湯張り水位制御手段Ｄにより決めら
れた設定水位ａはその記憶手段Ｇに記憶させ、常時一定
の湯張りができるようにしている。The set water level a determined by the water filling water level control means D is stored in the storage means G so that hot water can be filled at a constant level at all times.
【００２３】前記構成の給湯制御装置において、その作

In the initial circulation means C of 04, automatic hot water tap (water supply valve)
is turned off and closed, hot water supply is temporarily stopped, the flow path switching device is turned on to open it, the circulation pipe is switched to the circulation flow path, and at the same time, the circulation pump is turned on and started.
【００２６】しかして、浴槽内の初期基準水位の湯は循

ものである。The circulation for air removal in step 104 is performed for a predetermined period of time, and is controlled by the circulation detecting means E in step 105, for example.
If the circulating water flow switch is ON for more than a predetermined time, it is determined that there is an initial reference water level, and then the circulation pump is stopped. If the circulating water flow switch is not turned on for more than a predetermined time, the first automatic operation in step 100 is performed again. This returns the system to hot water supply control.

This water level detection value (for example, -20 mm) is compared with the initial reference water level detection value at the position of the bus adapter, etc., and the lower detection value is adopted as the reference water level.

自動給湯風呂釜の給湯制御装置。Claim 1: In an automatic hot water supply bath pot equipped with an automatic hot water supply means for a bathtub, a water level detection means in the bathtub, and a circulation pump that forcibly circulates hot water in the bathtub when reheating the bathtub, when the hot water is automatically supplied for the first time, When the water level detection means detects the initial reference water level at the location of the bus adapter, etc., the hot water supply is temporarily stopped and switched to the circulation flow path, and the circulation pump is started to circulate hot water at the reference water level for a predetermined period of time during hot water supply piping. An initial circulation means that bleeds air from the circulation flow path, which is a reference water level detection part, calculates the water level for filling the bathtub based on the initial reference water level detection value and the water level detection value after circulation, and calculates the water filling level from the result. A hot water supply control device for an automatic hot water supply bath kettle, characterized in that a hot water filling water level control means for setting the hot water filling water level is provided, and the hot water filling water level is determined from water level detection values before and after circulation.
