Microcirculation by-pass 9 is additionally provided between water pipe, check valve 3 and circulating pump 7 are provided with the microcirculation by-pass, it is described
The controlling switch of water pump is connected with the controller, and temperature sensor, the temperature sensor are provided with the constant temperature cabin
(not drawn in figure) is connected with controller, and the water temperature in constant temperature cabin is adjustable state, adjust different water temperatures as needed and
Reach the purpose of constant temperature, while temperature sensor can also be adjusted for water temperature, so as to reach the purpose of controller control.This
Invention between existing constant temperature of water heater cabin delivery port and water inlet by setting microcirculation by-pass, when the water in constant temperature cabin
Situation is fed back to by controller by temperature sensor after temperature decline, controller will control pump switch, start pump working, together
Shi Qidong Water heater igniting combustion gas is begun to warm up, and 5 be gaspipe in figure, and the water pump in constant temperature cabin is heated to heat exchanger,
In current direction constant temperature cabin after heating, when temperature reaches the temperature pre-set, controller control switch pump, pump stops
Work, gas ignition extinguish.It is going round and beginning again in this way, ensureing water temperature of the water temperature all the time in setting in constant temperature cabin, Neng Goubao
Card rapid hot water output when bathing is needed, ensure that the neutralization constant temperature effect in constant temperature cabin, while having saved water resource
Improve the comfortableness of bathing and improve constant temperature cabin and effectively utilize heat.The present invention not only increases effective utilization in constant temperature cabin
Heat, with water space, constant temperature cabin water temperature can be adjusted according to situation；When can also effectively reduce each ignition of complete machine
Cool water quantity, ensure the neutralization constant temperature effect in constant temperature cabin；By microcirculation, antifreeze area is needed in the winter time, is started micro-
