を放出するようにした自動排水装置などがある。 Conventional drainage devices for preventing water heaters from freezing in bathtubs with outdoor water heaters, etc. are equipped with an intake valve at the water supply port and a drain valve at the drain port to prevent freezing when the temperature is low and there is a risk of freezing. A manual drainage device that prevents freezing by manually opening the intake valve and drainage valve to release water in the device, and the intake valve,
There is an automatic drainage device in which the drain valve is a hydraulic automatic type, and when the water supply valve is closed at low temperatures, the valve body is opened by spring pressure and water is discharged.

しかしながら手動排水装置は操作が面倒でかつ
忘れがちとなり易く好ましくなかつた。 However, manual drainage devices are not preferred because they are troublesome to operate and easy to forget.

さらに自動排水装置の場合においては水道水圧

ことを特徴とする自動給排水装置にある。 The present invention was made to solve the above problems, and was made for the purpose of providing an automatic water supply and drainage device that is easy to operate and works reliably. A solenoid valve for water supply and intake, a solenoid valve for hot water supply/intake at the hot water supply port, and a solenoid valve for draining water at the drain port are provided, and the solenoid valve can be opened and closed by turning the power switch ON and OFF to allow water to flow or drain. Located in automatic water supply and drainage equipment.

以下第１図にもとづき本考案の実施例につき説

５および電磁石４を有する排水用電磁弁である。 An embodiment of the present invention will be described below based on FIG. 1. Reference numeral 10 indicates a water governor 11, a heat exchanger 12,
This is a water heater that has a built-in water passage 9 and the like. Reference numeral 13 designates a water supply and intake solenoid valve provided at the water supply port 8, which includes an electromagnet 4 and a valve body 5 that moves up and down. 1
Reference numeral 5 indicates an electromagnet 4 and a spring 5 provided at the hot water supply port 1.
This is a solenoid valve for hot water supply and intake having a valve body 5 that is laterally biased by a. Reference numeral 14 designates a drainage electromagnetic valve which is provided at the drainage port 2 and has a valve body 5 and an electromagnet 4 which are laterally biased by a spring 5a.

１６は電源スイツチである。 6 is a conductor that sends current from the power source 17 to each electromagnet;
〓〓〓〓
16 is a power switch.

本考案は上記の構成からなるので、電源スイツ
チ１６をONとすると各電磁弁の電磁石に電流が

体５が左側に吸引される吸気口７が閉ざされる。
さらに排水用電磁弁１４は弁体５が右側に吸引さ
れ放水口７が閉ざされる。 Since the present invention has the above configuration, when the power switch 16 is turned on, current flows through the electromagnet of each solenoid valve, but in the water intake solenoid valve 13, the valve body 5
The suction port 3, which is sucked upward, is closed and the water passage is opened. Further, in the hot water supply and intake electromagnetic valve 15, the intake port 7 where the valve body 5 is drawn to the left side is closed.
Furthermore, the valve body 5 of the drainage electromagnetic valve 14 is attracted to the right side, and the water discharge port 7 is closed.

したがつて給水口８から流入した水は図中矢印
で示すように通気路９中を流れ加熱されて温水が
給湯口１から放出される。 Therefore, water flowing in from the water supply port 8 flows through the ventilation path 9 as shown by the arrow in the figure, is heated, and hot water is discharged from the hot water supply port 1.

次に低温となり凍結の恐れがなる場合には電源
スイツチ１６をOFFにすると電流が遮断される
ため各電磁弁の弁体は夫々前記と逆方向に動き給
水口８からの給水が止まるとともに吸気口３，７
及び放水口７ａが開放されるため通水路９内の水
はすべて放水口７ａから排水され残留水がなくな
るので凍結を防止することができる。 Next, when the temperature is low and there is a risk of freezing, turning off the power switch 16 will cut off the current, so the valve bodies of each solenoid valve will move in the opposite direction to the above, stopping the water supply from the water supply port 8 and the intake port. 3,7
Since the water outlet 7a is opened, all the water in the water passage 9 is drained from the water outlet 7a, and there is no residual water, so freezing can be prevented.

操作が容易であることも本考案から生れた実益で
ある。 In this way, when using the present invention, water is reliably supplied and drained from the water heater by simply turning the power switch ON and OFF, and no water remains in the water heater when hot water is not needed. Not only can the product life be extended, but it is also extremely effective in preventing freezing. Another practical benefit of the present invention is that the solenoid valve can be opened and closed using a power switch installed indoors, that is, remote control is easy.

なお本実施例においては給湯口に吸気用電磁弁
を設けたが場合によつてはこれを除いても本考案
の目的を達することができる。 In this embodiment, an intake electromagnetic valve is provided at the hot water supply port, but in some cases, the purpose of the present invention can be achieved even if this valve is omitted.
