As an improvement, the water exit end of the heating water circulation pipe can connect the water inlet of the bypass by the first tee tube
Pipeline section, the backwater section of the heating water circulation pipe connect the return water pipeline section of the bypass by the second tee tube；
The water inlet segment is equipped with inlet valve, and the return water pipeline section is equipped with back-water valve (BWV).In this way, can needs when
The phenomenon that time opens bypass, avoids when without using life water, and life water water exit end is persistently heated, it is energy-saving.
It is preferred that being equipped with switch valve on the water exit end of the heating water circulation pipeline, the switch valve is located at the bypass
Downstream.To facilitate the season for not needing heating to use zero cold water function.
For the use convenient for each living water pipeline, it can be equipped at least two on the water exit end of the living water pipeline and go out
The mouth of a river.The quantity of water outlet can match with the quantity of living water pipeline.
Use the dual-purpose stove of above-mentioned each zero cold water structure, it is characterised in that the bypass is located at the plate heat exchanger of dual-purpose stove
Heating water inlet downstream.
The downstream of plate heat exchanger life water out described in the water exit end of the living water pipeline.
As a further improvement of the foregoing solution, it can also be equipped in the entry position of the water exit end of the living water pipeline
Temperature sensor；
The inlet valve, back-water valve (BWV) and switch valve are all connected with the control system of dual-purpose stove.The program can be realized zero cold water
The automatic control of function, and bypass can be closed when the water temperature in living water pipeline reaches requirement.
Compared with prior art, zero cold water structure provided by the utility model and dual-purpose stove, by the design of bypass,
Life water water exit end is arranged in bypass, heating water is introduced to the cold water retained in heating living water pipeline in bypass, in this way
Hot water can be flowed out in the moment that life tap is opened, avoids using zero water supply pump, has saved cost, and do not need to interrupt
The circulation of heating water also ensures the requirement of heating.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model embodiment use state；
Fig. 2 is the schematic diagram of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As depicted in figs. 1 and 2, which includes heating water circulation pipeline 1, living water pipeline 2 and bypass 3.
Wherein bypass 3 is connected between the water exit end 11 of heating water circulation pipeline 1 and backwater section 12.In the present embodiment, adopt
The water exit end 11 of warm water-circulating pipe connects the water inlet segment 33 of the bypass, the heating water circulation pipe by the first tee tube 41
Backwater section 12 the return water pipeline section 34 of the bypass is connected by the second tee tube 42.
The water inlet segment 33 of bypass is equipped with inlet valve 36, and the return water pipeline section 34 of bypass is equipped with back-water valve (BWV) 37.
