According to the 6th method, during the filling of foam-thermal insulation 6, the installation position pressing plate Oi of outer pin 7 presses, so the installation position of the outer pin 7 of base plate 3e can keep plane, outer pin 7 reliably can be fixed on the base plate 3e of outer container 3.Therefore, hot water storing tank unit 1 stabilisation is set.
The filling operation example > of the foam-thermal insulation 6 of < variation
Next, the operation example near the installation position of the outer pin 7 of the outer container 3 when filling the foam-thermal insulation 6 of variation is described.
Figure 16 is the synoptic diagram of the filling operation example of the foam-thermal insulation representing variation.
The hot water storing tank unit 1 of the embodiment of hot water storing tank unit 1A and Fig. 1 of the filling operation example of the foam-thermal insulation of the variation of Figure 16 is different, becomes the structure of the outer container 3A of the outer pin 7 not having outer container 3.
In the inside of outer container 3A, bolted, welding etc. is utilized by the multiple strength member 3K being used for hot water storing tank unit 1A to be arranged on setting place G to be fixed on header board 3a, side plate 3b, 3b, rear plate 3c etc. near base plate 3e.
Hot water storing tank unit 1A is placed in setting place G, make to be inserted through the through hole 3A1 being inserted through the side being formed at outer container 3A with the fixing bolt bo that foundation bolt ba is fixed on the through hole of the installing component T of setting place G, and screw togather with the internal thread part 3K1 of strength member 3K.Thus, outer container 3A is fixed on setting place G, and hot water storing tank unit 1A is arranged at setting place G.
As shown in figure 16, installing component T has the shape of such as L-shaped when side-looking, preferably puts into by the inclined strut parts s shown in double dot dash line to improve the intensity of installing component T.
Or preferred installing component T is such as formed as the shape in advance inclined strut parts s being put into the such triangular prism of installing component T when side-looking, improve the intensity of installing component T.
In variation, because there is no the outer pin of outer container 3A, so press outer container 3A with the work piece holder 30c of simple shape as shown in Figure 7, can between hot water storing tank 2 and outer container 3A filled and process heat-insulating material 6.
Therefore, work piece holder 30c can be simple shape, so can carry out filling operation at low cost.In addition, work piece holder 30c is utilized can reliably to press outer container 3A, so not from the leakage of the foam-thermal insulation 6 of the inside of outer container 3A.
In addition, at the side lower part of outer container 3A, by installing component T stationary heat water store tank unit 1A, so installing component T can be made to be also used as the isolation component of Earthquake Countermeasures.
In addition, because be the structure not arranging outer pin 7 at outer container 3A, the situation that the aspect ratio of hot water storing tank unit 1A arranges outer pin 7 is low.Therefore, the height of the wrapping corrugated paper of hot water storing tank unit 1A is low, and the foamed polystyrene of the packaging material of hot water storing tank unit 1A just can complete less, so have conveying cost advantage so less.
Liner > between < hot water storing tank 2 and outer container 3 (3A)
Figure 17 is the perspective elevation being contained in the hot water storing tank in outer container of observing hot water storing tank unit from oblique upper.
< liner sp >
Between hot water storing tank 2 and outer container 3, to stop outer container 3 to be deformed into object relative to hot water storing tank 2, be configured with and support multiple liner sp of outer container 3 relative to hot water storing tank 2 and multiple dual-purpose safeguards liner sm.Liner sp and dual-purpose safeguard that liner sm is fixed on the inner face of outer container 3 respectively with adhesives, two-sided tape etc.
Liner sp has rectangular shape, is formed by the resin of foamed polystyrene, polyurethane etc.The size that the size in the direction between hot water storing tank 2 with outer container 3 of liner sp is set as and desired size between hot water storing tank 2 and outer container 3 is almost identical.Like this, utilize liner sp to support between hot water storing tank 2 and outer container 3, thus suppress the distortion of outer container 3.
Liner sp configures multiple in the axis (long side direction) of hot water storing tank unit 2, and multiple in the peripheral direction configuration with substantial cylindrical shape of hot water storing tank unit 2.Now, what preferably make the axis (at long side direction) of multiple liner sp is configured as roughly the same interval, and make the peripheral direction of multiple liner sp be configured as roughly the same interval.By making the interval of multiple liner sp roughly the same, for the external force putting on outer container 3, the distortion of outer container 3 can be suppressed equably.
In addition, liner sp if can keep the size between hot water storing tank 2 and outer container 3, then also can have the shape beyond rectangular shape.
< dual-purpose safeguards liner sm >
Dual-purpose safeguards that liner sm has the drum at the radial direction of hot water storing tank 2 with central shaft, is formed by the resin of foamed polystyrene, polyurethane etc.
Dual-purpose safeguards that liner sm has following feature, that is, have columned gap (space) sm1 at central part collecting temperature sensor 5, and at inside collecting temperature sensor 5.
Dual-purpose safeguards the size in the direction between hot water storing tank 2 and outer container 3 of liner sm, and namely the size of the central axis direction of drum is set as the size almost identical with the desired size between hot water storing tank 2 and outer container 3.Liner sm supports outer container 3 between hot water storing tank 2 and outer container 3 to utilize dual-purpose to safeguard, thus suppresses the distortion of outer container 3.
In addition, dual-purpose safeguards that liner sm has columned gap (space) sm1 of collecting temperature sensor 5, so the maintenance of temperature sensor 5 is easily carried out.
In addition, if safeguard that liner sm has gap (space) sm1 at dual-purpose, then the shape of gap (space) sm1 also can adopt the shape beyond cylindrical shape.In other words, if dual-purpose safeguards that liner sm has gap (space) sm1 for safeguarding temperature sensor 5 at central portion, then its shape can suitably be selected.
, as shown in figure 17, if make gap (space) sm1 become cylindrical space, then there is around temperature sensor 5 impartial space, so maintenance is easily carried out.Further, if make gap (space) sm1 become cylindrical space, then formed easily.
In addition, if make dual-purpose safeguard, the profile of liner sm is for cylindric, then when arranging dual-purpose and safeguarding liner sm, do not have directionality, so processing ease.
