厨房及洗手台上所需的热水通常由一般的热水器直接供应，然而习用的热水器通常以导热片将燃烧器的热量传导至水管，对水管内冷水加温，这种热水器的火源完全由水压控制，水龙头一打开，便有燃气溢出，再由母火点燃，不仅加热慢，而且极易导致瞬间燃烧不完全，随着水龙头开关频繁程度的增加，这种瞬间燃烧不完全的现象愈加严重，从而不仅不安全、浪费燃气和水源，而且缩短热水器的使用寿命。The hot water needed in the kitchen and washstand is usually directly supplied by ordinary water heaters. However, conventional water heaters usually use heat conduction fins to transfer the heat from the burner to the water pipes to heat the cold water in the water pipes. The fire source of this water heater is completely Water pressure control, once the faucet is turned on, there will be gas overflowing, and then ignited by the main fire, not only the heating is slow, but also easily lead to incomplete combustion in an instant, as the frequency of faucet opening and closing increases, the phenomenon of incomplete combustion in an instant Seriously, it is not only unsafe, wasting gas and water sources, but also shortens the service life of the water heater.
本实用新型的目的是提供一种安全可靠、使用性能好、节约能源和水源、使用寿命长的带保温结构的热水器。The purpose of the utility model is to provide a water heater with thermal insulation structure which is safe and reliable, has good performance, saves energy and water, and has a long service life.
