される。(Prior Art and its Problems) There is already a bathtub with a water heater of the type described above, which was published in Utility Model Application No. 1983-43000. This is the fourth
The configuration is as shown in the figure, with a first heat exchanger 1 for hot water supply and a second heat exchanger 2 for baths installed in body A, and bathtub B and each of the heat exchangers as shown in the figure. Plumbed.
すなわち、浴槽Ｂに設けた水管３ａ，３ｂのう

プＰが挿入されている。 That is, of the water pipes 3a and 3b provided in the bathtub B, the water supply circuit 11 from the first heat exchanger 1 is connected to the lower water pipe 3b, and the water supply circuit 11 from the second heat exchanger 2 is connected to the lower water pipe 3b.
The inlet side of the circulation heating circuit 21 via the water pipe 3
b, and a circulation pump P is inserted into this inlet side circuit.
また、この循環加熱回路２１の出口側は上方の
水管３ａに接続されている。 Further, the outlet side of this circulation heating circuit 21 is connected to the upper water pipe 3a.
この先行技術のものでは、浴槽内水位が設定水
位になつたときに所定の信号を出力する水位スイ
ツチ４が給湯回路１１に設けられ、この水位スイ
ツチ４からの出力が制御装置Ｃに入力されて、こ
の制御装置Ｃにより第１熱交換器１からの給湯動
作（湯張り動作）、及び、その後浴槽内を所定の
温度に焚き上げるための動作、つまり、第２熱交
換器による循環加熱動作等が制御される。 In this prior art, a water level switch 4 that outputs a predetermined signal when the water level in the bathtub reaches a set water level is provided in the hot water supply circuit 11, and the output from this water level switch 4 is input to the control device C. , this control device C controls the operation of supplying hot water from the first heat exchanger 1 (filling operation), and the subsequent operation of heating the inside of the bathtub to a predetermined temperature, that is, the circulating heating operation of the second heat exchanger, etc. is controlled.
従つて、このものでは、湯ばり状態では、第１
熱交換器１から給湯回路１１を介して浴槽Ｂに貯
湯され、貯湯水位が一定水位に達すると、これを
水位スイツチ４が検知して制御装置Ｃの出力によ

び第２熱交換器２側が動作状態になつて浴槽Ｂ内
が循環加熱される。 Therefore, in this product, in the hot state, the first
Hot water is stored in the bathtub B from the heat exchanger 1 via the hot water supply circuit 11, and when the stored hot water level reaches a certain level, the water level switch 4 detects this and stops the hot water supply by the output of the control device C, and then the pump P and the second heat exchanger 2 side are brought into operation, and the inside of the bathtub B is circulated and heated.
このように、この先行技術のものでは、浴槽内
に所定水位まで給湯する所謂湯張り動作から、湯
張り動作完了後浴槽内を所定の温度にまで加熱す
る焚き上げ動作までの動作が自動的に進行するこ
ととなる。 In this way, in this prior art, the operations from the so-called hot water filling operation, which supplies hot water to a predetermined water level in the bathtub, to the heating operation, which heats the inside of the bathtub to a predetermined temperature after the hot water filling operation is completed, are automatically performed. It will proceed.
このものでは、強制循環加熱方式を採ることか
ら、第５図の如く、浴槽Ｂと器体Ａとの間に距離
がある条件下においても、水管３ｂに対応する部
分の配管を延長させることにより、器具が設置で
きる。 Since this device uses a forced circulation heating method, even under conditions where there is a distance between the bathtub B and the vessel A, as shown in Fig. 5, by extending the piping corresponding to the water pipe 3b. , equipment can be installed.
ところが、上記形式の器具をそのまま遠隔配管
した場合には、浴槽への湯ばりの際、貯湯量が十
分でない（設定水位に達しない）時点で制御装置
が動作し、湯ばりが停止される不都合が生じる。 However, if the above-mentioned type of equipment is connected directly to remote piping, there is the inconvenience that when filling a bathtub with hot water, the control device operates when the amount of stored hot water is insufficient (does not reach the set water level), stopping the filling of hot water. occurs.
これは、給湯回路１１が水管対応部を含めて長
くなることから、この部分の配管抵抗が大きく、
浴槽Ｂ内水位が設定水位に達しない時点で前記配
管抵抗分の圧力が付加されて水位スイツチ４の感
圧部分に作用し、この時点でこの水位スイツチが
動作してしまうからである。 This is because the hot water supply circuit 11 is long including the water pipe corresponding part, so the piping resistance in this part is large.
This is because when the water level in the bathtub B does not reach the set water level, the pressure corresponding to the piping resistance is applied and acts on the pressure sensitive part of the water level switch 4, and the water level switch is activated at this point.

（作用）
本考案の上記技術的手段は、次のように作用す
る。(Means) The technical means of the present invention taken to solve the above-mentioned technical problems are as follows .
A hot water supply circuit 11 that is connected to the bathtub B and has a solenoid valve 12 inserted therein which is opened by the hot water filling operation, a bath function section H2 that is provided separately from this hot water supply circuit, and a bathtub B.
a forced circulation heating circuit 21 that connects the forced circulation heating circuit 21, a pressure detection type water level detection means 40 inserted into the forced circulation heating circuit 21 and provided within the appliance, and a temperature sensor that detects the temperature of the hot water in the forced circulation heating circuit 21. 22, in the hot water filling operation state by hot water filling operation from the hot water supply function section H1 via the hot water supply circuit 11, the electromagnetic valve 12 is closed when the water level detected by the water level detection means 40 reaches the set water level. A control device C that stops the forced circulation heating when the temperature detected by the temperature sensor 22 reaches a predetermined heating temperature in the forced circulation heating state by the bath function section H2 . (See Figure 1) (Operation) The above technical means of the present invention operates as follows.
給湯回路１１と強制循環加熱回路２１とが器具
から浴槽Ｂに至るまでの間で別個に設けられてお

熱回路２１を介して水位検知手段４０に達する。
このとき、水位検知手段４０は給湯回路１１とは
別の回路に設けられているから、これに前記給湯
回路１１からの給湯圧力が作用しない。 Therefore, in the hot water filling state, the forced circulation heating circuit 21
Hot water is supplied to the bathtub B via a hot water supply circuit 11 separate from the bathtub B, and the pressure corresponding to the water level in the bathtub B reaches the water level detection means 40 via the forced circulation heating circuit 21.
At this time, since the water level detection means 40 is provided in a circuit separate from the hot water supply circuit 11, the hot water supply pressure from the hot water supply circuit 11 does not act on it.
従つて、水位検知手段４０は浴槽Ｂ内が設定水
位になつた時点で正確に所定の信号を出力し、こ
の時点で湯張り動作が停止される。 Therefore, the water level detection means 40 accurately outputs a predetermined signal when the water level in the bathtub B reaches the set water level, and the water filling operation is stopped at this point.
（効果）
本考案は上記構成であるから次の特有の効果を
有する。(Effects) Since the present invention has the above configuration, it has the following unique effects.
給湯回路１１からの給湯圧力に影響されること
なく、浴槽Ｂ内の水位に正確に対応して水位検知
手段４０が動作するから、先行技術のような湯張

（実施例）
以下、本考案の実施例を第２図及び第３図に基

することとなる。 In this embodiment, like the prior art described above, the water level detection means 40 is a pressure-sensitive water level switch 4, and the output from the water level switch 4 is input to the control device C. The solenoid valve 12 inserted into the hot water supply circuit 11 is controlled by the output from the pump, and the pump P inserted into the forced circulation heating circuit 21 and the combustion section on the second heat exchanger 2 side serving as a bath function section are controlled. Ru. That is, when hot water is filled from the first heat exchanger 1 to the bathtub B by the hot water filling operation and the water level in the bathtub B reaches the set water level, an output signal from the water level switch 4 is input to the control device C, and the water level in the bathtub B reaches the set water level. Filling is stopped by the output from control device C,
At the same time, the pump P starts and the second heat exchanger 2
The combustion section of the combustion chamber enters a combustion state, and forced circulation heating progresses.

るものである。 Further, a temperature sensor 22 that detects the heating temperature in the bathtub B is inserted into the forced circulation heating circuit 21, and the output from this temperature sensor is input to the control device C, and the output of this control device is used to control the second heat. A solenoid valve 23 inserted into the gas circuit to the exchanger 2 side is controlled to open and close. The combination of the second heat exchanger 2 and the gas burner of the bath function section consisting of a gas burner is of a known configuration, and the ignition operation proceeds simultaneously with the opening of the solenoid valve 23, or the ignition operation proceeds at all times when the appliance is in operation. During combustion, the flame transfers from the starter flame and becomes combustible.
