提供一种冰箱,其通过在冰箱的绝热箱体中使用阻燃性绝热材、特别是采用板状无机纤维成型体的真空绝热体,而能对于由外部火灾引起向冰箱箱体的延烧谋求绝热材的阻燃化、同f时即使采用可燃性制冷剂也安全且节能性高。
Description
技术领域
本发明涉及一种冰箱,特别是涉及一种确保绝热材的阻燃性、提高安全性,同时提高绝热性、提高节能性的冰箱。
背景技术
以前,冰箱是通过在由配置有绝热材的箱体所形成的空间内设置冷冻循环的蒸发器,使蒸发器中的冷气与外部绝热从而冷却或冷冻保存食品等。
近年来,以节能化和省空间化等为目的,具有高绝热性能的真空绝热体引起了人们的注意。作为真空绝热体的一例,存在:用阻气性层压薄膜包覆由具有连续气泡的硬质聚氨酯泡沫等构成的芯材并使内部减压而形成的,将填充有无机材料粉末的内袋装入外袋并使外袋减压而形成的等,其与硬质或软质聚氨酯泡沫等发泡树脂体相比较具有约2.5倍的绝热性能。
现有的冰箱构成中,当冰箱周围发生火灾时,若延烧至绝热箱体,则发泡树脂体不具有防止燃烧的效果,其结果是有时因外部的延烧而引起绝热材燃烧。另外,在冰箱中使用绝热性能高的真空绝热体来提高绝热性能,对于节能和提高内部容积是有效的。可是,采用发泡树脂体作为其芯材的真空绝热体,无助于冰箱绝热材的阻燃性。另方面,采用无机材料粉末的真空绝热体对于阻燃性有效是为人们所认同的,不过,作为绝热体其成型性差而难以作为冰箱用绝热材而适用。
再有,在近年作为用以应对地球温室化的对策的可燃性制冷剂而适用HC制冷剂时,防止从外部着火源到冰箱的延烧显得更加重要,现有的绝热材不能应对那些课题。
发明内容
本发明,即是为了解决上述现有课题,目的在于将采用阻燃性板状无机纤维成型体的阻燃性真空绝热体使用于冰箱箱体上,防止由外部火灾引起的向冰箱箱体的延烧,即使使用可燃性制冷剂也可以实现安全的节能性高的冰箱。
为了解决上述课题,本发明的冰箱,其绝热箱体具有以阻气性薄膜包覆板状无机纤维成型体且使内部减压的真空绝热体和发泡树脂绝热体。通过在绝热箱体中配置采用板状无机纤维成型体的阻燃性真空绝热体,从而与只采用发泡树脂体的绝热材相比较,阻燃性得到改善,其结果是绝热箱体的阻燃性提高。因此,能谋求外部引起的延烧的绝热箱体的阻燃化,能获得比现有冰箱安全性更高的冰箱。另外,由于配置真空绝热体,从而能减少绝热箱体所使用的发泡树脂体的量,还由于改善绝热性能而使绝热箱体的薄壁化也成为可能,从而,其结果是能进一步减少所使用的发泡树脂体的总量。从而,由于所使用的发泡树脂体的量减少,因而能在绝热材万一发生延烧时减少有机气体的发生量,获得安全性更高的冰箱。
另外,由于采用板状无机纤维成型体,因而能获得平面性优良、轻量且生产性优良的冰箱。
另外,本发明的冰箱,在由内箱和外箱形成的空间中具有绝热材,在空间的外箱侧使用采用板状无机纤维成型体的真空绝热体。在这种情况下,在冰箱的外侧面配置阻燃性的真空绝热体,从而,即使从冰箱外部引起延烧,真空绝热体也难以燃烧,因此,其结果是着火难以引到发泡树脂体上,而能更加提高作为箱体的阻燃性。
另外,门体上也使用采用阻燃性板状纤维成型体的绝热材,因此,能相对于从冰箱外部引起的延烧而提高冰箱门体的绝热部的阻燃性。
另外,具有将冰箱内独立隔开的分隔箱体,分隔箱体中配置有采用板状无机纤维成型体的真空绝热体。从而,由于从外部引起的延烧而使箱内独立的冷冻室、冷藏室中任意一方的室内发生燃烧时,也由于分隔箱体而难以燃烧,因而能防止向其他室内的延烧,获得安全性更高的冰箱。
另外,本发明的冰箱,在构成冰箱箱体的外箱和内箱之间形成的密闭空间中配置板状无机纤维成型体、使空间内部减压,其结果是在密闭空间内不具有发泡树脂体。从而,能谋求阻燃性的大幅度提高,从延烧时不会从发泡树脂体发生有机气体这个意思来说,能大幅度地提高安全性,还能使绝热箱体成为真空绝热箱体,因此绝热性能也大幅提高。
另外,板状无机纤维成型体至少含有二氧化硅。采用含有二氧化硅的无机纤维,从而能获得耐热性优良且廉价的真空绝热体。
另外,板状无机纤维成型体至少含有氧化铝。采用含有氧化铝或使氧化铝含有率提高的无机纤维,从而能进一步提高耐热性,采用这种材料的真空绝热体的阻燃性进一步提高。

图3是本发明的实施例2的冰箱的剖面图。
具体的实施方式
下面,参照附图对本发明的实施例进行说明。
实施例1
图1是本发明的实施例1的冰箱的剖面图。冰箱主体1由绝热箱体2、分隔箱体3、门体4及构成冷冻循环的压缩机5、冷凝器6、毛细管7、蒸发器8构成。绝热箱体2和门体4,由铁板等冲压成型的外箱9和ABS树脂等成型的内箱10构成。
由绝热箱体2和门体4形成的空间是冰箱的箱内部,由分隔箱体3区划成上下空间,上部形成冷藏室11,下部形成冷冻室12。
将压缩机5、冷凝器6、毛细管7和蒸发器8顺次连接成环状,形成冷冻循环。本实施例中在冷冻循环内封入HC制冷剂异丁烷作为制冷剂。蒸发器8,被设在冷冻室12中,介由风档13向冷藏室11送入冷风。另外,也可以在冷藏室11及冷冻室12两个地方设置蒸发器8,将其串联或并联相接、形成冷冻循环。
绝热箱的空间14和门体的空间15中配置真空绝热体16和发泡树脂绝热体17。本实施例中的发泡树脂绝热体17是硬质聚氨酯泡沫,采用环戊烷作为发泡剂使其发泡。另外,分隔箱体3中配置真空绝热体16。
本实施例中的真空绝热体16,采用板状无机纤维成型体作为芯材,由阻气性薄膜包覆该芯材、使其内部减压而形成真空绝热体16。板状无机纤维成型体的构成材料没有特别限定,可以是氧化铝纤维、陶瓷纤维、二氧化硅纤维、氧化锆纤维、玻璃棉、石棉、硫酸钙纤维、碳化硅纤维、钛酸钾纤维、硫酸镁纤维等无机纤维,另外,也不限定单一素材。另外,无机纤维的纤维径,出于绝热性能方面考虑优选10μm以下、更优选5μm以下、特别优选3μm以下。
另外,虽然可以只是纤维材料的,不过为了形成聚集体还可以采用无机粘合剂或有机粘合剂。作为上述无机粘合剂,并不特别限定,可以使用人们所熟知的材料,如:胶体二氧化硅、水玻璃、低熔点玻璃、氧化铝溶胶、硅树脂等。
另外,作为上述有机粘合剂,并不特别限定,可以使用人们所熟知的材料,如:酚醛类树脂、环氧类树脂、脲醛类树脂等热硬化性树脂;或者丙烯酸甲酯、丙烯酸乙酯、丙烯酸丁酯、氰基丙烯酸酯、甲基丙烯酸甲酯、甲基丙烯酸乙酯、甲基丙烯酸丁酯、氰基甲基丙烯酸酯等丙烯酸类树脂,聚对苯二甲酸乙二醇酯、聚对苯二甲酸丁二醇酯、聚萘二甲酸乙二醇酯等聚酯,聚丙烯、聚乙烯、聚苯乙烯、聚醋酸乙烯、聚乙烯醇、聚丙烯腈、或聚酰胺类树脂等热塑性树脂等。
有机粘合剂的含有量,出于阻燃性、随着时间变化而来自无机纤维成型体的发生气体、或者密度等的观点考虑,优选10%以下,更优选5%以下。这些粘合剂可以采用2种或者2种以上的混合物,还可以混合通常用的可塑剂、热稳定剂、光稳定剂、填充材料等使用。可以将以上材料混合而使用、或者也可以将这些材料用水或人们熟知的有机溶剂稀释而使用。
在上述无机纤维上涂敷上述粘合剂或其稀释液,或者将无机纤维浸渍在上述粘合剂或其稀释液中,从而使粘合剂附着其上。之后,若粘合剂是稀释液,则根据需要使其溶剂干燥后,进行压缩或加热压缩,从而成为板状无机纤维成型体。另外,也可以使无机纤维在上述粘合剂的稀释液中分散、抄浆,从而获得成型体。
如上所述制作而成的板状无机纤维成型体的密度没有特别限定,不过,出于能够维持作为成型体的形状的观点考虑,优选在80kg/m3以上,另外,出于绝热性的观点考虑,优选在400kg/m3以下,特别优选在150kg/m3以上、300kg/m3以下。
图2表示真空绝热体16的剖面图。其构成是,板状无机纤维成型体18填充在作为外覆材料的阻气性薄膜19中,内部减压至30Pa左右。
上述所谓的阻气性薄膜,内部包覆芯材用以设置气密部,作为材料构成没有特别限定,存在将例如由最外层的聚对苯二甲酸乙二醇酯树脂、中间层的铝(以下称为Al)箔、最内层的高密度聚乙烯树脂构成的塑料叠片薄膜,和例如由最外层的聚对苯二甲酸乙二醇酯树脂、中间层的具有Al真空镀膜的乙烯-乙烯醇共聚体树脂(商品名EVAL、kuraray(株)制)、最内层的高密度聚乙烯树脂构成的塑料叠片薄膜形成袋状的薄膜等。
作为外覆材料的构成上的特征:最外层是用以应对冲击等的、中间层是用以确保阻气性的、最内层是用以利用热粘接性进行密闭。因此,只要是达到这些目的,所有人们熟知的材料都能使用,再有,作为改善的方案,还可以:在最外层附加尼龙树脂而提高耐穿透性、在中间层设置2层具有Al真空镀膜的乙烯-乙烯醇共聚体树脂。
另外,作为热粘接性的最内层,从密封性、化学腐蚀性等方面考虑优选高密度聚乙烯树脂,不过,除此之外,还可以采用聚丙烯树脂、聚丙烯腈树脂等。
另外,外覆材料的袋形状可以是四方密封袋、带衬袋(gusset袋)、枕袋(pillow袋)、L字袋等,不特别限定。
另外,为了芯材的脱水、脱气,也可以在向外覆材料插入前实施加热处理。出于能够进行最低限脱水的考虑,此时的加热温度优选100℃以上。
另外,要使真空绝热体16的可靠性更进一步提高时,还可以使用气体吸附剂、水分吸附剂等吸气剂物质。
另外,其吸附机构,可以是物理吸附、化学吸附及吸收贮藏、吸着等任意一种,不过作为非蒸发型吸气剂而作用的物质其效果良好。
具体地说,可以是合成沸石、活性碳、活性氧化铝、硅胶、dosonite(ド-ソナイト)、水滑石等物理吸附剂。
作为化学吸附剂,可以利用碱金属、碱土类金属等的氧化物或碱金属、碱土类金属等的氢氧化物等,特别是氧化锂、氢氧化锂、氧化钙、氢氧化钙、氧化镁、氢氧化镁、氧化钡、氢氧化钡有效地发挥作用。
另外,硫酸钙、硫酸镁、硫酸钠、碳酸钠、碳酸钾、氯化钙、碳酸锂、不饱和脂肪酸、铁化合物等也有效地发挥作用。另外,适用将钡、镁、钙、锶、钛、锆、钒等物质单独或合金化构成的吸气剂物质更加有效。再有,为了至少吸附除去氮、氧、水分、二氧化碳,因此,将这些上述吸气剂物质多种混合适用更有效。
如此,作为芯材采用板状无机纤维成型体而制成的真空绝热体16的表示绝热性能的热传导率在30Pa的减压条件下为0.0043W/mK。另方面,作为芯材采用连通形聚氨酯或粉末二氧化硅而制成的真空绝热体的热传导率在30Pa时为0.0065~0.0075W/mK。因此,本实施例的真空绝热体16与现有的真空绝热体相比较具有约1.5倍以上的绝热性能。如此,由于绝热性能非常高,因此,即使是薄的真空绝热体16也能确保足够的绝热性能,从而能增大冰箱主体1的箱内容积。
另外,真空绝热体16采用板状无机纤维成型体的芯材,因此,能获得薄且平面性优良的真空绝热体16,从而能使绝热箱体2的绝热壁薄且平面性好。
另外,切断、弯折及形成凹陷、突起部、贯通孔等的加工性也非常优良,因此,能容易获得按照冰箱主体1形状的真空绝热体16。例如,可以将1片真空绝热体16沿着冰箱主体1的绝热箱体2的三侧面弯折、使用,通过形成这种形状,从而也能用真空绝热体包覆冰箱箱体的边缘部,因此,能够获得阻燃性更加优良、且绝热性优良的冰箱绝热箱体2。
另外,通过在绝热箱体2中将期望比其他部分的壁薄的部位使用一块板、而在除此之外部分层叠两块板,从而能非常简单地制作出符合需要的形状。而且,真空绝热体16的芯材为板状,因此在层叠成需要的厚度时也能对应宽幅的要求。
另外,在真空绝热体16上配置冰箱主体1所必需的管或导线等时,可以在板状无机纤维成型体上设置沿管等形状的凹陷再制作真空绝热体16,或者是在制作真空绝热体16后设置凹陷,而将管等配置在该凹陷中。另外,还可以相对沿着箱体内面的管等直接按压真空绝热体形成凹陷,而直接将真空绝热体16配置在箱体内面。如此,由于采用纤维聚集体而能容易成型,容易设置凹陷。
另外,由于采用无机纤维,因此,由往冰箱主体1的外箱9和内箱10形成的空间14内填充树脂发泡体17时的温度上升而带来的真空绝热体16的性能劣化,较之使用有机物芯材的真空绝热材时可以得到抑制。此时,采用无机粉末的真空绝热体,在将无机粉末插入外覆材料前,需要首先往内袋中填充粉末。这是因为:无机粉末若不预先填充到内袋,则在将外覆材料内进行真空排气时粉末会发生飞散。往内袋填充粉末、制作真空绝热体时,在进行真空绝热体的形状加工时首先需要调整内袋形状。在采用板状芯材的情况下,形状加工时只要将板状芯材切断、弯折成需要的形状就能获得需要形状的真空绝热体,但在采用粉末的真空绝热体中,为了将内袋调整成需要形状,由于会发生内袋破裂、粉末偏移而限制形状加工,作业效率也非常差。如此,采用板状无机纤维成型体的真空绝热材16为板状成型体,因此,和使用无机粉末时相比较,制作真空绝热体16时还能大幅地提高作业效率。可以省略采用粉末时作为必要工序的粉末的内袋填充,还不用担心粉末飞散而能大幅地改善作业环境。再有,真空绝热体16破袋时芯材也不会飞散,因此,即使废弃冰箱时也不会导致作业环境的恶化,能容易废弃具有该真空绝热体16的冰箱。另外,不是粉末而是将纤维状物质形成成型体,因此,形成成形体时纤维彼此间的接触点多,能容易用粘合剂等进行固形而获得制作容易的芯材。
本实施例中,绝热箱体2具有真空绝热体16和发泡树脂绝热体17。发泡树脂绝热体17,可以使用硬质聚氨酯泡沫、酚醛泡沫和苯乙烯泡沫等,不过,并未特别指定。另外,作为使例如硬质聚氨酯泡沫发泡时使用的发泡剂,并未特别指定,不过,出于保护臭氧层、防止地球温室化的观点,优选环戊烷、异戊烷、n-戊烷、异丁烷、n-丁烷、水(碳酸气体发泡)、偶氮化合物、氩等,特别出于绝热性能方面尤其优选环戊烷。
本实施例中,将这种真空绝热体16配置在绝热箱体2的外箱9侧,还在内箱10侧配置有发泡树脂绝热体17。也可以将真空绝热体16配置在外箱9内面,之后,使发泡树脂绝热体17发泡填充在外箱9与内箱10间形成的空间14内而形成绝热壁。或者,也可以将使真空绝热体16与发泡树脂绝热体17一体发泡的绝热体、配置在外箱9与内箱10间形成的空间14且使真空绝热体16在外箱9侧。通过在冰箱主体1的外侧面配置阻燃性的真空绝热体16,从而能进一步提高相对冰箱主体1外部引起的延烧的绝热材的阻燃化,提高安全性。
另外,在冰箱主体1的背面、侧面、顶面配置多个由板状无机纤维成型体18形成的阻燃性真空绝热体16,能提高作为绝热箱体2整体的阻燃性,而成为安全性更高的冰箱。另外,通过将阻燃性真空绝热体16只配置在绝热箱体2侧面、背面或底面任意一处以上的与冷冻室12所对应的部分,从而在成本或绝热性能方面也能高效率地粘贴。
另外,本实施例中,安装于冰箱主体1上的门体4采用板状无机纤维成型体18。作为门体4所采用的真空绝热体16,采用的方法是在门体4的内侧面或外侧面粘贴采用板状无机纤维成型体18的真空绝热体16、用发泡树脂绝热体17填充其以外的空间。另外,也有一种方法是首先用真空绝热体16与发泡树脂绝热体17制作成多层绝热板、再将其夹在门体4内部或用胶带等进行粘贴。再有方法是在门体4内部配置板状无机纤维成型体18、将门体4内部进行真空排气而使门体4自身形成真空绝热体等。由于门体4采用阻燃性真空绝热体16,所以,万一在冰箱主体1周围起火燃烧也能谋求阻燃性以应对向门体4的延烧。
并且,在本实施例中,具有将冰箱主体1内独立隔开的分隔箱体3,在上述分隔箱体3中配置真空绝热体16。也可以:在上述分隔箱体3内部只配置真空绝热体16、用由ABS树脂和PP树脂等形成的分隔箱体外框20包覆周围而形成分隔箱体。
另外,可以使真空绝热体、发泡树脂绝热体与分隔箱体外框一体成型来形成分隔箱体,这时也可以将分隔箱体外框与内箱一体成形。或者也可以:预先用真空绝热体和发泡树脂绝热体制作成绝热板、再收入到分隔箱体外框内而形成分隔箱体,只要是配置有采用板状无机纤维成型体的真空绝热体的分隔箱体即可,并未特别指定。通过如以上那样构成分隔箱体,且,例如在绝热箱体的内箱侧配置采用板状无机纤维成型体的真空绝热体,从而即使在冰箱外部发生着火燃烧时,即使冷藏室前面部的门被打开而发生箱内燃烧,也能防止向由分隔箱体隔开的其他室内的延烧而获得安全性高的冰箱。
另外,由分隔箱体3区隔开的冰箱主体1内可以分为冷藏室11、冷冻室12,它们的位置关系也可以为顶部冷冻室、中部冷冻室、底部冷冻室等,没有特别指定,另外,也可以:在大型冰箱等中纵向也具有分隔箱体,而使左右任意部分为冷藏室、冷冻室。
作为本实施例的真空绝热体16的配置方法,预先在真空绝热体16的单面、或外箱9内侧的真空绝热体16粘贴位置、或其两面涂敷热熔剂(hot-melt),之后,将真空绝热体16按压在外箱上、通过施加压力使真空绝热体16粘贴在绝热箱体2上,之后,用由硬质聚氨酯泡沫形成的发泡树脂绝热体17发泡填充在外箱9和内箱10间形成的空间14中。
另外,在将真空绝热体16配置在绝热箱体2的侧面时,为了使该真空绝热体16与绝热箱体2的形状相一致,也可以例如沿机械室21的形状在图1中的右下部配置具有切口部的真空绝热体16。另外,此时,真空绝热体可以包覆绝热箱体的侧面整体,也可以只包覆热漏泄大的冷冻室12所对应的绝热箱体部,还可用多个真空绝热体包覆侧面。
另外,将设在冰箱主体1背面下部的机械室21与冷冻室12分离的绝热箱体2的绝热部上的真空绝热体16,沿机械室21的形状弯折。真空绝热体16采用无机纤维成型体18为芯材,因此弯折加工非常容易、生产性优良。
另外,以下表示图2所示的真空绝热体16的制造方法。真空绝热体16,是将厚5mm的板状无机纤维成型体18在140℃干燥1小时后、再插入外覆材料19中,将内部抽成真空、密封开口部从而形成。板状无机纤维成型体所采用的化学纤维的化学组成是,二氧化硅约60%、氧化铝约18%、氧化钙约17%、其他无机物约5%,纤维径约1~3μm。另外,与此相对应,作为粘合剂使用约5%的丙烯酸类粘合剂,该成型体的大气压下的密度为120kg/m3。
外覆材料19,一面上是由作为表面保护层的聚对苯二甲酸乙二醇酯(12μm)、作为中间部的铝箔(6μm)、作为热密封层的高密度聚乙烯(50μm)构成的塑料叠片薄膜;另一面上,是由作为表面保护层的聚对苯二甲酸乙二醇酯(12μm)、作为中间部的薄膜层、作为热密封层的高密度聚乙烯(50μm)构成的塑料叠片薄膜,该薄膜层是在乙烯-乙烯醇共聚体树脂组合物(15μm)内侧施以Al真空镀膜而形成的。
另外,在外覆材料19上,为了提高耐损伤性,而在表面保护层上形成尼龙树脂层。另外,外覆材料19的袋形状采用四方密封形的。
实施例2
图3表示本发明的实施例2的冰箱的剖面图。冰箱主体1由绝热箱体24构成,且该绝热箱体24由外箱22、内箱23和配置在其空间中的板状无机纤维成型体18形成。绝热箱体24中重叠使用2片以上的板状无机纤维成型体18。外箱22和内箱23由厚0.5mm的铁板构成,接缝由焊接封住而保持内部的气密性。另外,由同样的铁板等还形成分隔箱体25。分隔箱体25内也配置板状无机纤维成型体18。另外,外箱22、分隔箱体25上分别设有排气孔26、27用以将内部进行真空排气,而且,在将绝热箱体24、分隔箱体25内部抽成真空后,利用焊接封闭排气孔26、27以保持内部的气密性。此时,为了获得冰箱背面的平面性,该排气孔26的突起部可以在保持气密性的范围内切掉。门体28,用厚0.5mm的铁板形成外框,内部配置板状无机纤维成型体18后、将其内部进行真空排气,再利用焊接封住排气孔29。
另外,蒸发器8被配置在冰箱主体1的箱内,与外部的冷冻循环部件进行管连接。此时,这些管与绝热箱体24,在绝热箱体24的内箱23与外箱23的接缝部分30、31进行焊接以保持绝热箱体24内部的气密性。
板状无机纤维成型体18,沿上述管的形状形成凹陷,并在那里镶嵌管,由于无机纤维成型体18是板状而形状加工非常容易、凹陷形成等得以简单进行。本无机纤维的氧化铝含有率约18%,而增大氧化铝含有率会提高结晶性从而耐热温度上升,因此,将采用氧化铝含有率更大的无机纤维的板状无机纤维成型体18使用于冰箱,能获得安全性高的冰箱。另外,为了保持绝热箱体24和门体28等内部的真空度,还可以在内部配置气体吸附剂。
根据如此构成,由于绝热壁不具有发泡树脂绝热体,所以冰箱的安全性大幅度提高。这是因为,即使万一从冰箱外部延烧也由于不具有有机性的绝热材,而能抑制向绝热材延烧,还能抑制从发泡树脂绝热体发生有机气体。此时,外箱和内箱最好是阻气性好且热传导率低的物质,而实际上非常薄的铁板、不锈钢板等金属板很有效。由于外箱和内箱之间采用板状无机纤维成型体,因而平面性优良,将外箱和内箱的内部进行真空排气时也能保持冰箱表面的平面性。另外,在生产时也与无机粉末等不同,只要将板状无机纤维成型体插入外箱与内箱之间、将内部抽成真空即可,因此在生产性和作业性上也非常优良。另外,由于采用无机纤维,因而真空绝热体内的随时间变化的发生的气体少,绝热箱体的长期可靠性也提高。
另外,板状无机纤维成型体的构成中至少含有二氧化硅,从而,能获得耐热性优良且廉价的板状无机纤维成型体。
另外,板状无机纤维成型体的构成中至少含有氧化铝,从而,氧化铝含有率越多则绝热材的耐热性越提高,因而能提高板状无机纤维成型体的阻燃性。另外,板状无机纤维成型体也可以含有其他成分,作为除此之外的无机物,没有特别指定,可以是氧化钙、氧化镁、氧化铁、氧化钛、氧化硼、氧化钠、氧化锆、硫酸钙、硫酸镁、碳化硅、钛酸钾、氧化铬、氧化锌等。
另外,本实施例的冰箱中,作为制冷剂,采用对地球温室化影响少的HC制冷剂。如此,在采用可燃性制冷剂时,与现有的HCFC制冷剂和CFC制冷剂等相比较,应对火灾等的对策变得很重要,由于采用本实施例中所述的无机纤维成型体,从而能提供安全性高的冰箱。因此能提供可以兼顾安全性和保护地球环境的冰箱。
产业上的可利用性
如上所述本发明的冰箱,其构成是:绝热箱体具有真空绝热体,该真空绝热体采用板状无机纤维成型体,并且由阻气性薄膜包覆、使内部减压。因此,阻燃性比只采用发泡树脂体的绝热材得到改善,其结果是绝热箱体的阻燃性提高。因此,能谋求外部延烧的绝热箱体的阻燃化,获得比现有冰箱安全性高的冰箱。
