本発明は給湯用の湯水混合装置の逆流防止手段に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to backflow prevention means for a hot water mixing device for hot water supply.
従来の技術
従来この種の湯水混合装置には、第４図に示すようなも
のがあった。（例えば実開昭５５−５９２２３号公報）
第４図において、湯の入口１と水の入口２と混合湯の出
口３を有した弁框体４内には、湯［１１１弁体５と水側
弁体６が軸７に固定して設けられている。2. Description of the Related Art Conventionally, there has been a hot water mixing device of this type as shown in FIG. (For example, Japanese Utility Model Publication No. 55-59223) In Fig. 4, a valve body 4 having a hot water inlet 1, a water inlet 2, and a mixed hot water outlet 3 has a hot water [111] valve body 5 and a water A side valve body 6 is fixedly provided to the shaft 7.

てれる。The shaft 7 is driven by a motor 10 through a threaded structure 8 and an external reduction gear 9, and moves up and down in the figure, and the hot water side valve body 5 and the water side valve body 6 change the mixing ratio of hot water and water. It will be done. The mixed water temperature is detected by a boomister 11, and this detection signal is compared with the set temperature of a setting device 12 by a controller 13, and the motor 10 is adjusted. The mixed hot water is then supplied from the faucet 14.
発明が解決しようとする問題点
しかしながら上記のような構成では、蛇口１４を閉成し
た時に、湯１１弁体５と水側弁体６が開いているため圧
力の高い側から低い側に湯、水が流入するおそれがあっ
た。Problems to be Solved by the Invention However, in the above configuration, when the faucet 14 is closed, the hot water 11 valve body 5 and the water side valve body 6 are open, so hot water flows from the high pressure side to the low pressure side. There was a risk of water inflowing.
特に給湯材が安全弁を備えた方式の場合、水圧の方が高
いと、水側から湯側に伝播した圧力により安全弁が閉成
し、貯えてあった湯が抜けてしまうことがあった。In particular, when the hot water supply material is equipped with a safety valve, if the water pressure is higher, the pressure propagating from the water side to the hot water side may close the safety valve and cause the stored hot water to escape.
また、断水時に蛇口１４が開成された状態であると、蛇
口１４にホースが付けられて汚水中に端末が投入されて
いると、汚水が逆流し、湯、水経路に汚水が充満される
衛生上の問題があった。In addition, if the faucet 14 is left open during a water outage, if a hose is attached to the faucet 14 and the terminal is placed in sewage water, the sewage will flow back and the hot water and water channels will be filled with sewage. I had the above problem.
これらを防止するために、湯の入口１や水の入口２に逆
止弁を付設することも行なわれていたが、通常使用時の
圧力損失を低くおさえるため弱いばねで付勢されていた
ため、逆流時の防止効果が十分でなく、上記と同様な問
題点が発生することがなかった。In order to prevent these, check valves were installed at the hot water inlet 1 and the water inlet 2, but they were biased with weak springs to keep the pressure loss low during normal use. The prevention effect at the time of backflow was not sufficient, and the same problem as above did not occur.
本発明はこのような従来の問題点を解決するものであり

The hot water and water that have passed through the hot water side control valve 19 and the water side control valve 20 pass through a pressure balance valve 27 that balances the pressure and reach a mixing valve 28. The mixing valve 28 is driven by a motor 29. The hot water and water whose mixing ratio has been adjusted are mixed in the mixing chamber 30, and the thermistor 31, flow rate sensor 32, and mixing valve 2
The hot water is supplied to the hot water supply target via the flow rate control valve 33, which constitutes a part of the hot water supply system 8. A setting device 34 is provided in the hot water supply target,

When the setting device 34 instructs the start of hot water supply, the hot water side control valve 19, the water side control valve 20, and the flow rate control valve 33 are closed, hot water flows, and mixed hot water is supplied at a predetermined flow rate and temperature. . The set temperature and flow rate can be changed using the setting device 34. Setting device 34
When an instruction is given to stop hot water supply, the supply of mixed hot water is stopped by closing the hot water side control valve 19, water side control valve 20, and flow rate control valve 33. During this stop, the flow control valve 33 is closed slowly, so the solenoid 2
．． 24 is being driven. During stoppage, the hot water @1 control valve 19 and the water side control valve 20 close the flow path, so no backflow occurs. If the water supply stops during hot water supply, solenoid 23
．． 24 is closed and hot water supply is stopped. This is useful, for example, to prevent a power outage while filling a bathtub with hot water, resulting in hot water being supplied at a temperature different from the set temperature, or preventing the bathtub from overflowing due to the inability to count the integrated flow rate.

調節弁、止水弁を兼ねている所に特徴がある。The mixing valve 50 is of a type whose temperature is controlled by a wax thermostat and is driven by a guard motor 51. A position detector 52 is provided on the output shaft of the geared motor 51 in order to set the temperature. Mixed hot water is flow rate sensor 53
, thermistor 54. The thermistor 54 is for controlling the hot water temperature in a minute range that cannot be controlled by the wax thermometer. Setting device 55, thermistor 54,
The flow rate sensor 53, the guard motor 51, and the motor 48 are connected to a controller 56. Reference numeral 57 denotes a backup power source, which uses a battery, a capacitor, or the like to maintain control during a power outage, or rotates the motor 48 to close the hot water side control valve 38 and the water side control valve 39. This embodiment is driven by one electric drive means, serves as both a backflow valve and a control valve, and the control valves on the hot water side and water side also serve as flow rate adjustment valves and water stop valves. The place has its own characteristics.
第３図は第３の実施例を示すものである。FIG. 3 shows a third embodiment.

を回転させ湯側流路５８と水側流路５９の連通を断つ。Hot water and water entering from the hot water side path 58 and the water side path 59 are mixed by a mixing valve 602. The mixing valve 60 includes a ceramic fixed valve body 61, a valve operating body 62, and an externally provided drive unit 63.
It consists of When the hot water supply is not used, the valve body 62
is rotated to cut off communication between the hot water side flow path 58 and the water side flow path 59.

るために流量制御弁６６を先に制御している。When the hot water supply is stopped or there is a water outage, the mixing valve 60 closes the flow path, but it is closed after the flow control valve 66 is closed or at a stage where most of the flow rate control valve 66 is closed. This is because the structure of the mixing valve 60 is such that when it is closed, the hot water side and the water side are mixed and communicated, first the hot water side is closed, and then the water side is closed. The hot water gets cold and stops supplying water, leaving you feeling uncomfortable when using the shower. To prevent this, the flow rate control valve 66 is controlled first.
