Therefore, in existing heat accumulation water pot unit, it is known that as supply to heat accumulation water pot
In the case that water uses the high hardness waters such as well water, when pipe arrangement uses the copper alloys such as brass, because of timeliness
Deterioration and pipe arrangement inner surface corrodes, cause stress-corrosion cracking (referring for example to bibliography 1:
" big Tianjin military logical " stress-corrosion cracking of copper alloy ", anticorrosion technique, Vol.12 (1963),
No.9, P412-423, or,
Https: //www.jstage.jst.go.jp/article/jcorr1954/12/9/12_9_413/_pd f is international mutual
Networking, Heisei retrieval on August 1st, 26 ").Therefore, for the purpose of tackling this problem, design
Make all stainless products of pipe arrangement class (for example, referring to patent document 1).
But, the situation of the high hardness waters such as well water is not used at the water as supply to heat accumulation water pot
Under, it is not required to consider the problem of the corrosion of pipe arrangement inner surface, therefore due to cost-benefit pass
System, pipe arrangement uses the example of copper alloy common.
On the other hand, in the heat accumulation water pot unit 1A of embodiments of the present invention, no matter supply
Being which species to the water of heat accumulation water pot 2, it is right that the pipe arrangement of the inside being accommodated in outer container 3A all uses
Amine or ammonia have the pipe arrangement of corrosion resistance.Specifically, at least bag being accommodated in outer container 3A
Include feed pipe the 11st, oral siphon the 12nd, hot-water outlet pipe the 13rd, heat supply water pipe the 14th, bathtub return pipe 15
All pipe arrangements by amine or ammonia are had corrosion resistance pipe arrangement constitute.In addition, this place
Meaning pipe arrangement refer to either bobbin (pipe), flexible pipe (tube), coiled pipe (hose) etc. which kind of
The concept that all of which is included by pattern.
The reason using the pipe arrangement being formed by the material to amine or ammonia with corrosion resistance is as follows.
As described above, in the heat accumulation water pot unit 1A of embodiments of the present invention, outer container 3A with
The expanding foam solution 6a of foaming heat insulation parts 6 is injected in gap between heat accumulation water pot 2.This expanding foam solution 6a
In the contained hydroxyl of polyalcohol and the NCO of isocyanates composition react and formed
Polyurethane.When forming polyurethane, by making foaming agent foam, become polyurathamc, by
The foaming heat insulation parts 6 that polyurathamc is constituted are not filled in outer container 3A and water storage with having space
Between tank 2.The foaming heat insulation parts 6 being made up of this polyurathamc from once synthesize because of attachment
Hydrolyzable that moisture (such as dew) around heat accumulation water pot 2 and pipe arrangement is caused or
The decomposition that caused because of the heat of surrounding and persistently deteriorate.The hydrolyzable of following presentation polyurethane is anti-
The example answered or the example of the thermal decomposition of polyurethane.
[chemical formula 1]
[chemical formula 2]
Herein, chemical formula 1 is the adding water of polyurathamc representing and forming foaming heat insulation parts 6
The chemical equation of the example decomposing, chemical formula 2 is to represent to form sending out of foaming heat insulation parts 6
The chemical equation of the example of the thermal decomposition of bubble polyurethane.R, R in formula ' for example represent alkyl.
In addition, R, R ' both can be identical, it is also possible to different from each other.It is attached to heat accumulation water pot 2 and pipe arrangement
The moisture of surrounding for example can enumerate dew.Additionally, the surrounding of heat accumulation water pot 2 and pipe arrangement
The situation of the heat such as heat directly heat transfer of the hot water of the inside of consideration heat accumulation water pot 2 and pipe arrangement,
Or consider to be passed by indirect underground heat such as its gaps in the case of being surrounded with vacuum heat-insulation parts 5
Situation about leading.
Carbonyl in the structural formula of general polyurethane is easily subject to water (H2O) oxygen (O) causes
Necleophilic reaction.Accordingly, because the ammonia ester bond in polyurethane reacts with the moisture of surrounding,
Polyurethane be decomposed (hydrolyzable) be isocyanates composition and polyol component.Additionally, it is poly-
Ammonia ester bond in urethane key between C-O is more weak, and polyurethane is divided owing to being exposed to hanker
Solving (thermal decomposition) is isocyanates composition and polyol component.
And, the NCO of the isocyanates composition being generated by the decomposition of polyurethane and water
Reaction, thus isocyanates composition is broken down into amine component and the carbon dioxide (CO with amino2)
(hydrolyzable).
[chemical formula 3]
As shown in chemical formula 3, when isocyanates composition is by hydrolyzable, generate one-level amine and
Carbon dioxide.In the case that in chemical formula, the alkyl (R) of amine is hydrogen atom (H), should
Amine becomes ammonia (NH3), generate ammonia.To this in other words, as shown in chemical formula 1～3, pass through
The decomposition of above-mentioned foaming heat insulation parts 6, generates amine or ammonia.
But, the ammonia so producing for example as the corrosive medium of the copper alloys such as brass by extensive
Solve, and be known as ammonia and be very easy to be dissolved in water so because humidity is affected.I.e.,
Know in the atmosphere of ammonia, the stress-corrosion cracking (example of the copper alloys such as brass occurs very significantly
P418 " 32 ammonia " joint as with reference to above-mentioned bibliography 1).
Therefore, in the case that pipe arrangement is made up of Cu alloy materials such as brass as prior art,
Unrelated with the water quality such as hardness of water of supply, due to the foaming being made up of polyurathamc every
The ammonia that the deterioration that the decomposition of thermal part 6 is caused carries out and produces, and there is the external table of pipe arrangement
The corrosion in face.And, when deterioration is gone down further, there are the feelings causing stress-corrosion cracking
Condition.

In addition, as such concrete candidate couple to amine or ammonia with corrosion resistance pipe arrangement
As being for example both stainless pipe arrangement or resinous pipe arrangement.Additionally, also
The pipe arrangement of the material beyond them can be.Further, for example when parts such as the joints at pipe arrangement
Be simultaneously used as combining polymer obtained from sulphur (condensate) in phenyl ring, heat-resisting resistance to
During the parts of Compressive Strength aspect of performance excellent PPS (polyphenylene sulfide) resin, not only corrosion-resistant
Property is excellent and deflection is also suppressed, it may be said that more preferably.Additionally, for example make corrosion-resistant
In the case that property pipe arrangement is stainless pipe arrangement, as the advantage beyond corrosion resistance, additionally it is possible to
Enjoy and be difficult to attachment dirt at outer surface, be difficult to attachment incrustation scale at inner surface, be difficult to equivalence of getting rusty
