おいて、２１は電磁式の三方弁である。The connecting tube portion 50 on the inlet side provided at the end portion of the case 5a is connected and communicated with the connecting pipe 32 which is the outlet pipe provided in the valve box 30 of the atmosphere opening valve 3 described above, and the other end side. Connection pipe 20 for connecting the connecting cylinder portion 51 of
The hot water supply from the hot water supply circuit 2 to the circulation circuit 1 through the atmosphere opening device T is connected to the pumping device 5
Case 5a
When hot water is supplied from the hot water supply circuit 2 to the circulation circuit 1 by connecting and communicating the suction pipe 53 protruding from the water pipe 40 with the drain pipe 40 of the waste water receiving hopper 4 of the atmosphere opening device T via the suction pipe 55, the flow of the hot water flows. Due to the suction operation of the Venturi pipe 5b due to excess, the drainage that has flowed out of the atmosphere communication port 33 when the hot water supply is stopped and is stored in the drainage receiving hopper 4 is sucked into the lumen of the Venturi pipe 5b which is the hot water supply passage. Then, it is collected in the circulation circuit together with the hot water flowing through.
At this time, when the pressure of the hot water flowing in the venturi pipe 5b is high, the check valve 54 prevents the hot water from flowing back to the drain receiving hopper 4 side. Also, the drainage receiving hopper 4
When the drainage in the inside is exhausted, the valve body 43 on the lower surface of the float 42 blocks the drainage port 41 and prevents air from being sucked into the venturi pipe 5b. Further, in the figure, 21 is an electromagnetic three-way valve.

In this example, the valve body 43 that is opened and closed by 2 is omitted, and instead of this, the electromagnetic valve V2 is provided in the middle of the suction pipe 55 that connects the drainage pipe 40 and the suction pipe 53. In this case, it is necessary to control the valve so that it will be closed when the drainage hopper 4 runs out of drainage.
When the valve mechanism V1 is opened by energization, the valve is opened with a delay of several seconds, and after that, the valve is kept open for several seconds and then closed. Since the remaining structure of this embodiment is the same as that of the above-mentioned embodiment, the same reference numerals are given to the constituent members having the same effect, and the detailed description thereof will be omitted.

に、簡単な構成で回収処理し得るようになる。As described above, the apparatus for collecting and treating waste water in the atmosphere opening device according to the present invention is such that when the hot water supply is stopped, the circulation circuit such as the hot water supply circuit 2 as the clean water circuit and the bath pot as the intermediate water circuit. When processing the wastewater stored in the wastewater receiving hopper 4 of the atmosphere opening device provided between the venturi pipe 5b and the passage through which hot water flows when hot water is supplied, a water supply circuit for hot water is supplied. The suction pressure is created by the flow of hot water flowing from the side to the middle water circuit side, and the suction pressure causes the waste water in the waste water receiving hopper 4 to be sucked into the hot water supply passage and is recovered to the middle water circuit side. The wastewater received by the wastewater receiving hopper 4 of the opening device can be collected and processed with a simple configuration without requiring an electric circuit.
