Hot Water Generator

摘要

A cold water intake pipe 4 and a hot water extraction pipe 5 that communicate with multiple spiral tubes 101 and a steam supplying pipe 2 and a condensate discharge pipe 3 that communicate with a shell are connected to a corrugated spiral tube type heat exchanger 1. Between the cold water intake pipe 4 and multiple spiral tubes 101, communication paths 46 that communicate between the cold water intake pipe 4 and some multiple spiral tubes 101a are provided, and a valve 44 is provided to communicate between the cold water intake pipe 4 and the other multiple spiral tubes 101b when the force acting from the cold water intake pipe 4 becomes larger than the force acting from the other multiple spiral tubes 101b and to block the cold water intake pipe 4 from the other multiple spiral tubes 101b when the force acting from the cold water intake pipe 4 becomes smaller than the force acting from the other multiple spiral tubes 101b.

1. A hot water generator in which a cold water intake pipe and a hot water extraction pipe that communicate with multiple spiral tubes and a steam supplying pipe and a condensate discharge pipe that communicate with a shell are connected to a corrugated spiral tube type heat exchanger,
wherein a communication path that communicates the cold water intake pipe with some of the multiple spiral tubes is provided between the cold water intake pipe and the multiple spiral tubes, and a valve is provided to communicate the cold water intake pipe with others of the multiple spiral tubes when a force acting from the cold water intake pipe becomes larger than a force acting from the others of the multiple spiral tubes and to block the cold water intake pipe from the others of the multiple spiral tubes when the force acting from the cold water intake pipe becomes smaller than the force acting from the others of the multiple spiral tubes.
