んとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an after-boiling prevention device for an instantaneous water heater. Initially, the water is allowed to flow through the sub-channel, and after a few seconds, the water flow to the sub-channel is cut off to prevent the water from boiling over.

1 is a heat exchanger of an instantaneous water heater, 2 is a main burner provided below the heat exchanger, and 3 is a gas valve. Reference numeral 4 denotes a main water passage leading to the hot water supply inlet via the heat exchanger 1, and numeral 5 represents a sub water passage that branches from the main water passage 4 and bypasses the heat exchanger 1. Reference numeral 6 denotes an after-boiling prevention device provided at a branch of the sub-channel 5, and an enlarged view thereof is shown in FIG. In the figure, 7 is a tank with a circular cross section, such as a hollow cylinder or sphere, and is placed in the middle of the main water passage 4. Reference numeral 8 denotes an inlet of a sub-water channel 5 branched from the tank 7. 9 is a water inlet pipe introduced into the tank 7, and 10 is a water outlet pipe leading from the tank 7 to the heat exchanger 1. Reference numeral 11 denotes a constriction part provided at the tip of the water inlet pipe 9, which is close to the entrance 8 of the sub-channel 5 and faces the spherical surface a.

り、高温の湯が供給されるのである。 The present invention has such a configuration, and when hot water is supplied, the hot water tap is opened and water is supplied. However, at the beginning of hot water supply, water does not rotate in the tank 7, and water flows from the water inlet pipe 9 to the tank 7. The water that has entered the water flows from the water outlet pipe 10 to the heat exchanger 1 and joins from the inlet 8 through the auxiliary water passage 5, and is heated to a temperature lower than the normal hot water supply temperature. Therefore, hot water does not gush out from the hot water supply opening in the initial stage of hot water supply.
After that (several seconds), the water flow flowing in from the water inlet pipe 9 becomes so-called mist-like due to the throttle part 11.
Since the circular tank 8 begins to rotate along the spherical surface a of the inner wall, the side of the auxiliary water passage 5 becomes negative pressure and water flows out only from the outlet pipe 10. This state is the normal hot water supply state, and high temperature hot water is supplied.
以上のように本発明は円形のタンクに副通水路
に至る入口を設け、この入口に接近して入水管の
絞り部を臨ませたので、水の回転を利用し簡単な
構造にて後沸きを防止することができる。 As described above, the present invention provides a circular tank with an inlet leading to the sub-water channel, and approaches this inlet to face the constricted part of the water inlet pipe, so that the after-boiling system uses the rotation of the water and has a simple structure. can be prevented.
しかも本発明においてはタンクの容量に応じて
副通水路への通水時間を自由に設定することがで
きるものである。 Moreover, in the present invention, the water flow time to the sub-channel can be freely set according to the capacity of the tank.
