追焚用熱交換器４を有する循環追焚き管路５に接続され
ている。In FIG. 5, reference numeral 1 denotes a hot water supply heat exchanger, which is connected to an appropriate hot water supply tap 2 at the hot water outlet pipe and is provided with a pouring pipe passage 3 branched from the hot water outlet pipe. It is connected to a circulation reheating pipe line 5 having a heat exchanger 4 for reheating bath water.

と接続されている。In the pouring pipe line 3, a pouring electromagnetic valve 6 and an edge cutting device 7 are provided.
And (details of which will be described later), a check valve 8 is sequentially arranged, and the end of the check valve 8 is circulated through the electric three-way valve 9 for circulation circulation heating line 5.
Is connected to

されている。14は浴槽、14aは循環口である。A pump 10 and a pressure sensor 11 for detecting the bath water level are arranged on the return side of the circulation reheating pipeline, and a check valve 13 is arranged in a bypass pipeline 12 bypassing the electric three-way valve 9. Has been done. 14 is a bathtub and 14a is a circulation port.

介して浴槽14中に注湯張し得るように構成されている。The edging device 7 pushes up the first valve body 71 and the second valve body 72 by the spring 73, and in this state, the second valve body 72 opens the air inlet 74 to separate the clean water and the bath water. However, when the pouring electromagnetic valve 6 is opened to pass water, the water pressure thereof pushes down the first valve body 71 and the second valve body 72 against the spring 73, and the second valve body 72 closes the air inlet 74. At the same time, the first valve body 71 is opened so that the molten metal can be poured into the bathtub 14 through the pouring pipe line 3 and the circulation reheating pipe line 5.

追焚き管路５中の水位が圧力センサ11より下方まで抜け
落ちて圧力センサ11で浴槽中の水位を検出することがで
きなくなることがある。In an automatic bathtub using an edge cutting device 7 for introducing air, when the bathtub is installed below the equipment, the pouring solenoid valve 6 is closed at the end of pouring and the electric three-way valve 9 is closed. If there is a delay before switching to, the air level is sucked in from the air inlet 74 of the edging device 7 and the water level in the circulation reheating pipeline 5 falls below the pressure sensor 11 and the pressure sensor 11 causes the water level in the bathtub to drop. May not be detected.

中の水位を検出することができなくなるおそれがある。Similarly, during pouring into the bathtub, when the hot water tap 2 on the hot water supply pipe side is opened and the amount of hot water flowing to the pouring water pipe 3 side suddenly decreases, the second valve body 72 of the edging device 7 causes the air inlet to move. There is a possibility that the pressure sensor 11 may not be able to detect the water level in the bathtub by moving so that the 74 and the pouring pipe line communicate with each other.

置を提供することを目的とする。The present invention solves the above-mentioned problems of the prior art, and despite the use of a device for cutting off the edge of clean water and bath water by introducing air, the water level in the circulation reheating pipeline is pressured. An object of the present invention is to provide a device that can reliably prevent the sensor from falling below the sensor.

に空気が流入するのを遮断することを特徴とする。In order to achieve the above-mentioned object, the present invention provides an edging device for introducing air into a pipe line except when water is passed in order to cut off the water between the tap water and the bath water. In an automatic bathtub provided in a pouring pipe connecting the hot water supply pipe and detecting a bath water level by a pressure sensor, in the pouring pipe downstream of the edging device or upstream of the pressure sensor. A negative pressure stop valve that opens and closes by the difference between the atmospheric pressure and the force set by the spring and the force that moves the valve body due to the pressure in the pipeline is installed in the circulation reheating pipeline of By closing the shut-off valve, it is possible to block the inflow of air into the pipeline from the edge cutting device to the bathtub or the circulation reheating pipeline.

のを遮断し、管路の水抜けを防止することができる。When the second valve body 72 in the edging device 7 moves so as to connect the air inlet 74 and the pipe line and sucks air from the air inlet 74, the inside of the pipe line is always at a negative pressure as compared with the atmospheric pressure. According to the present invention, the negative pressure shut-off valve that closes the pipeline using this negative pressure is provided downstream of the edging device and upstream of the pressure sensor, so that the negative pressure shut-off valve allows air to flow into the pipeline. It is possible to prevent this from happening and prevent water leakage from the pipeline.
以下、第１図ないし第４図について本考案の実施例の
一例を説明する。An example of an embodiment of the present invention will be described below with reference to FIGS.

Pouring pipe line, 4 is a reheating heat exchanger, 5 is a circulation reheating pipe line, 6 is a pouring solenoid valve,
7 is an edge cutting device, 8 is a check valve, 11 is a pressure sensor, 14 is a bath, and 14a is a bath circulation port. In the present invention, a negative pressure shutoff valve 15 is connected to the pouring pipe line 3 downstream of the edging device 7 and the check valve 8. However, the present invention is not limited to the one in which the negative pressure shut-off valve 15 is connected to the pouring pipe line by interposing it, and if the upstream side of the pressure sensor 11 is connected to the circulation reheating pipe line 5. It may be connected.

A valve body 155 supported by a diaphragm 154 on the valve seat 153, and the back surface of the valve body 155 has an atmospheric pressure port 15
The valve body 1 is opened to 6 and is lightly contacted with the valve seat 153 by the spring 157.
Only when the force pushing up 55 exceeds the force pushing down valve body 155 by spring 157 and atmospheric pressure is valve body 155
Push up to allow water flow. However, the negative pressure shutoff valve according to the present invention is not limited to this embodiment, and the spring 157 may be omitted in some cases. Alternatively, as shown in FIG. 4, without using a diaphragm, the valve body 155 ′ is moved by the spring 157 to the valve seat 153 ′.
It may be lightly contacted with. 158 is an O-ring.

力センサによる水位検出を行なうことができる。According to the present invention, as described above, the negative pressure stop valve 15 is provided with the edge cutting device 7.
Since it is provided on the further downstream side and on the upstream side of the pressure sensor 11, when air tries to flow in from the air inlet 74 of the edging device 7, the valve body 155 is brought into pressure contact with the valve seat 153 and the air flows into the pipeline. It is possible to prevent the water from leaking out of the pipeline by this, and to detect the water level by the pressure sensor.

ができる。The embodiment shown in FIG. 1 has a check valve 8 in the pouring pipe line.
Since the negative pressure shutoff valve 15 and the negative pressure shutoff valve 15 are arranged in series, there is no backflow of air or water from the air inlet of the edging device 7 even if a positive or negative pressure is applied from the circulation heating line side. It is possible to omit the use of the electric three-way valve 9 as in the conventional example shown in FIG.

作用効果を奏し得ることが明らかである。In a water heater having a high-temperature hot water supply function, the pouring electromagnetic valve 6 is opened to pour hot water having a temperature set in the remote controller into the bathtub, and when the bathtub temperature decreases, the pouring solenoid valve 6 is squeezed. In this state, hot water is poured into the bathtub, and in this case, it is clear that the negative pressure shutoff valve 15 can exert the same effect as that of the embodiment shown in FIG.
