Description
Technical field
The present invention relates to the hot water supply apparatus and the electric drive type hot water of vacuum heat insulation material, use vacuum heat insulation material.
Background technique
In recent years, from viewpoint, in home appliance, requiring to reduce the necessity of power consumption for global warmingization.For example, refrigerator is the product that consumes power consumption in household appliances, and the power consumption that reduces refrigerator becomes as the indispensable situation of global warming countermeasure.Under this type of situation, the refrigerator that adopts vacuum heat insulation material is by finished productization, and the unhelpful heat exchange of inhibition and outside also significantly improves heat-insulating efficiency.
As the main application fields of existing vacuum heat insulation material, be the beginning with the refrigerator, superfreeze device, transportation become the center with refrigerating box, product that refrigerator equitemperature band is lower.But,, use to bathtub and vending machine equitemperature band high product so begin one's study recently because its heat-shielding performance of vacuum heat insulation material is good.
Owing to use to this type of temperature high product field, the material that requires to constitute vacuum heat insulation material can be enough to bear this temperature band.The heat resisting temperature of the employed outsourcing material of vacuum heat insulation material also is the one example, as conventional example, the product shown in patent documentation 1 (spy opens flat 11-309069 communique) and the patent documentation 2 (spy opens the 2001-8828 communique) is arranged.
Vacuum heat insulation material shown in the patent documentation 1 is the example that uses vacuum heat insulation material in electronic water heater; but the laminated film that will dispose vacuum-packed vacuum heat insulation material between the heat resistance laminated film of core is made of sealing layer and innerliner and protective layer, and is the laminated film that heat seal lands is become ground, electronic water heater outside folded configuration.Because the temperature of electronic water heater rises to 100 ℃, so there is organic system thermal-protective material deterioration, thermal insulation such as the ammonia ester problem of non-constant that becomes all the time.The vacuum heat insulation material of patent documentation 1 is to address these problems and use no extension polypropylene at sealing layer in the outsourcing material of above-mentioned formation.Have heat resistance by using this material to constitute, and become and make heat seal lands near the water heater outside and suppress the structure of the deterioration of heat-sealing portion.
In addition, the example of the electronic water heater shown in the patent documentation 2 is vacuum heat insulation material to be set and to make the considerably less example of holding power in the tank periphery.This is because in the innerliner in the laminated film that constitutes vacuum heat insulation material, use metal foil in higher temperatures one side, use the evaporation layer in low temperature one side, so but high temperature one side tightness under 100 ℃ temperature keeps vacuum state well, and can keep thermal insulation for a long time.In addition, by using the evaporation layer in low temperature one side, and be suppressed at the heat of transmitting and flowing in the metal foil, and improve the performance of vacuum heat insulation material integral body, so reduced power consumption.
Vacuum heat insulation material shown in the patent documentation 1 has used aluminium foil and no extension polypropylene respectively for improving tightness and heat resistance, but can see duck eye on the thin aluminium foil of 6 μ m equal thickness, thereby is appreciated that the tightness that produces therefrom worsens.In addition, the tightness deterioration of using no extension polypropylene to be produced is not proposed concrete processing method, and become in-problem formation aspect reliability.
In addition, though the vacuum heat insulation material shown in the patent documentation 2 is by using metal foil layer and using the evaporation layer in low temperature one side in high temperature one side, and be suppressed in the evaporation layer heat (heat bridge) of transmitting and flowing into, but relatively tightness is relatively poor for evaporation layer and metal foil, so it is big to enter quantitative change from the gas of the evaporation layer of low temperature one side.That is reliability aspect existing problems.
In addition, as the new problem of under hot environment, using, exist from the influence of the organic system gas of laminated film generation.According to inventors' experiment, the film that uses the Bond such as ammonia ester system of two-package curing type and lamination can confirm that methyl alcohol is arranged, ethyl acetate, toluene, vinyl benzene equal solvent is that gas breaks away from every turn when rising to 80 ℃.Like this, composition and the phenomenon of decomposing the organic gas composition disengaging that becomes to grade that is produced have appearred.Under the situation that has the high material of tightness such as aluminium foil, the gas that produces in internal layer one side is difficult to penetrate an outer side, so be penetrated into the hot melt coating as internal layer one side.Under low temperature environments such as refrigerator, it is gas that normally used all the time moisture and gas absorbent can not adsorb these organic solvents, so can not keep the degree of vacuum of vacuum heat insulation material.Therefore, the result will cause the variation of heat-shielding performance.
For sorbent, there is no record in the patent documentation 1 and 2, these problems are not considered yet.
An example of existing vacuum heat insulation material is described below by Fig. 9 and Figure 10.
Fig. 9 is to use the sectional view of vacuum heat insulation material configuration portion of the product of vacuum heat insulation material, in the drawings, use the performance of " high temperature one side " and " low temperature one side " to put down in writing temperature difference for convenience.Figure 10, Figure 11 represent to be disposed at the structural profile of film 12a of high temperature one side and an example of structural profile that is disposed at the film 12b of low temperature one side respectively.
As shown in Figure 9, usually, vacuum heat insulation material 10 is made of core 11 and outsourcing material 12, stick on the wall material 20 of high temperature one side with Bond (not shown) etc., grasping part 25 and with the wall material 21 formation insulating portion of low temperature one side.In addition, for keeping inner degree of vacuum to use sorbent.Space 25 also exists under the situation of hard ammonia ester foam and other thermal-protective material.
Wherein, be disposed at the structure of film of high temperature one side of outsourcing material 12; possess sealer 14 and innerliner 15 and 16 and hot melt coating 17 and constituting as shown in Figure 10, be generally that tightness does not worsen and uses the situation of aluminium foil more under hot environment on innerliner 16.
In addition, as the structure of the film of low temperature one side that is disposed at outsourcing material 12, except as shown in Figure 11 resin film AM aluminum metallization on base material being used as the situation of innerliner 18, for the identical structure of high temperature one side of Figure 10.
In high temperature one side, considered the influence of the duck eye of aluminium foil, in low temperature one side, the evaporation aluminium lamination is compared poor air-tightness with original aluminium foil, even if tightness also is easy to descend in arbitrary structure.In addition, though the influence by high temperature one side, and produce the organic gas composition from the laminated portion self-adhesive agent of outsourcing material 12 and solvent etc., do not consider these.

The embodiment 1～6 of the initial explanation of table 1 expression and the summary of comparative example 1～4.In each example, to the membrane structure and the sorbent of separately outsourcing material, measure the heat conductivity at initial stage and with respect to through the heat conductivity after 5 years, and, the deformation state of outward appearance etc. is observed.
The 1st embodiment is the embodiment who constitutes the membrane structure of outsourcing material 52 in vacuum heat insulation material shown in Figure 1 50 as shown in Figure 2.Core 51 uses the glass wool lamination body that does not contain Bond of fiber diameter 4 μ m.
The concrete structure of expression embodiment's 1 outsourcing material 52.Use polyamide film (ONY) as outermost sealer 55; first innerliner 56 that specific surface protective layer 55 is provided with more in the inner part uses polyethylene terephthalate (PET) to be used as resin film 56a, and is used as metal evaporation layer 56b with the thickness AM aluminum metallization of 400～500 .In addition, second innerliner 57 is the aluminium foil of sneaking into iron (AL) of thickness 6 μ m.And, become structure with the relative applying of aluminium foil of the aluminium-vapour deposition face of first innerliner 56 and second innerliner 57.The high Bond of specific heat overlay 58 fusing points is used in the applying of metal evaporation layer and metal foil layer.Hot melt coating 58 uses no extension polypropylene film, and improves the heat resisting temperature as outsourcing material 52 integral body.
The sorbent 53 that holds in the inside of core 51 uses the hydrophily synthetic zeolite of average pore diameter 9 .The hydrophily synthetic zeolite adsorbs the gas of the molecular diameter littler than pore diameter with physical absorbent.In addition, though possess interior packaging material material 54 between outsourcing material 52 and the core 51, to surround core 51 more in the inner part, even packaging material material 54 can not yet in not using than outsourcing material 52.Under the state in outsourcing material 52 is wrapped in core 51 and sorbent 53 in the packaging material material 54 from outer side covers.
For the tightness of outsourcing material 52, make up by the metal evaporation layer that formed metal foil layer and the aluminium-vapour deposition of aluminium foil produced and to use, closed metal evaporation layer is with the peculiar duck eye of metal foil, and the result can strengthen tightness.Though the polyester type ammonia ester that is used in combination two-package curing type of each interlayer of film of outsourcing material 52 is a Bond, except two metal interlevels bondings that evaporation layer and paper tinsel layer are constituted, be not particularly limited.Have again, will remark additionally in the back for Bond.
Can so obtain vacuum heat insulation material 50: the core 51 that the glass wool lamination body is constituted is with 230 ℃ of dry certain hours, and cut otch with respect to the thickness direction inclination of core 51 and then put into sorbent 53, packaging material material 54 in it is packed into is with coexist on the thickness direction of core 51 compression and with the inside degassing and sealing for the time being of interior packaging material material 54 1.The outsourcing material 52 of drying process of it can being packed into, and in that an end-grain cutting of interior packaging material material 54 is disconnected and under the opened state after keeping a period of time below the degree of vacuum 2.2Pa, applies an end hot melt of outsourcing material 52.
For Bond, can further replenish.In the present embodiment, by the hot melt coating 58 deposited degree of vacuum that keep outsourcing material 52 inside, the fusing point of hot melt coating 58 is certainly than the employed temperature of vacuum heat insulation material (for example, being 110 ℃ in the hot water supply device) height.In addition, the fusing point height that is used for the certain specific heat overlay 58 of temperature of the thermal source that hot melt coating 58 is deposited.
Be used for Bond that metal interlevel is fitted, the fusing point height of specific heat overlay 58 as described above not only, and must use the material higher than deposited temperature.At this moment, the combination of metal interlevel can not break away from when in manufacturing process hot melt coating 58 hot melts being applied, and can keep high-air-tightness.
In the present embodiment, the Bond that is used in combination the thermosetting resin formation between metal foil layer and the metal evaporation layer.Thermosetting resin is the resin that solidifies in when heating, can deliquescing in case heat again even heat cured material solidifies also not, be suitable for situation about under high temperature environment, using.Particularly, the ammonia ester for polyester polyol system/polyisocyanate salt is a Bond.This Bond bonds by making the pure and mild polyisocyanate reactant salt of polyester polyols generate ammonia ester ammonia ester bond.That is, the adhesive film that is generated has formed ammonia ester bond.Therefore, can be described as polyurethane ammonia ester is that the binder-type polyester is a Bond.
This type of Bond exists in the situation of interrupting ammonia ester bond under certain temperature.The Bond of present embodiment, since about 200 ℃, the part ammonia ester bond begins fracture, but does not bondingly almost peel off on the microcosmic.It is about 1～2 second that actual hot melt covers needed time, and the fusing point of hot melt coating is 160 ℃, so also can not peel off even make outsourcing material 52 hot melts apply bonding.
In fact, the temperature of the thermal source when hot melt applies is 180～200 ℃, even and bond under the situation that outsourcing material 52 hot melts are applied and also can not peel off.Have again,, apply action, also can not observe deterioration at adhesive layer even in one minute, implement hot melt for the heat source temperature more than 200 ℃.
In addition, so-called heat bridge is even also caused by the high thermal conductivity that metal layer had in particular in each structure of outsourcing material 52.That is, in actual user mode, the temperature of metal layer (being aluminium foil and aluminium-vapour deposition film among the embodiment 1) has the tendency that is easy to raise.Therefore, the bonding of the bonding of two metal interlevels and other layer relatively is easy to break away from.
In the present embodiment, owing to use the Bond that above-mentioned thermosetting resin constituted, even in long-term the use, also can keep high-air-tightness.In addition, even the Bond that does not use thermosetting resin and constituted, the Bond that uses fusing point with specific heat overlay and hot melt to apply the high fusing point of temperature (heat source temperature) also can be expected same effect.
The heat conductivity of the heat-shielding performance of the vacuum heat insulation material 50 that expression so obtains is to be measured down for 24 ℃ in mean temperature by the heat conductivity testing apparatus AUTO-Λ that the great smart machine (strain) of English is made.Use Fig. 4 that the vacuum heat insulation material 50 of determination object is described.Fig. 4 is the sectional view that the vacuum heat insulation material 50 of heat conductivity is measured in expression.Same with example shown in Figure 1, cover cores 51 with outsourcing material 52, under the state of decompression with inner sealing.The part that with dashed lines surrounds is the 52a of ear of outsourcing material 52.Like this, have the 52a of ear on the peripheral portion of outsourcing material 52, though under the user mode of reality, (with reference to Fig. 1) used in many bendings, measures heat conductivity as shown in Figure 4 under the state that does not bend the 52a of ear.
When measuring heat conductivity, be expressed as the good like this value of 0.0022 (W/mK) in the early stage in the value.In addition, for the deterioration of the heat-shielding performance of using under hot environment, making maximum operation (service) temperature is 110 ℃, with consider certain service condition be equivalent to compare through the heat conductivity value after 5 years.Present embodiment be equivalent to be 0.0064 (W/mK), can to confirm the heat-shielding performance that keeps enough through the heat conductivity value after 5 years.In addition, the outward appearance of vacuum heat insulation material 50 is not special changes.
The 2nd embodiment, remove make sorbent 53 for calcium oxide with the identical condition making vacuum heat insulation material 50 of external application and embodiment 1.Calcium oxide is hydrophilic chemosorbent, hygroscopic moisture and become calcium hydroxide.
When the heat conductivity of the heat-shielding performance of the vacuum heat insulation material 50 that so obtains of expression is measured similarly to Example 1, initial value is 0.0021 (W/mK), present embodiment be equivalent to be 0.0068 (W/mK), can to confirm the heat-shielding performance that keeps enough through the heat conductivity value after 5 years.In addition, the outward appearance of vacuum heat insulation material 50 is not special changes.
