Description

双干衣滚筒的燃气干衣机 技术领域
本发明属于衣物处理设备技术领域，具体提供一种双干衣滚筒的燃气干衣机。
背景技术
随着人们生活水平的提升，人们对于日常衣物的处理更加看重，这就催生出了许多种对于衣物进行进一步处理的设备，干衣机便是其中一种，由于其能够快速烘干衣物，从而使用户使用体验得到提升，特别是在商用衣物处理领域，干衣机的出现显著提升了洗衣效率，增加了洗衣房的收入。
现有干衣机通常是以电为能源进行制热，然后进行烘干，此种设计结构简单且成本较低，但是在烘干阶段耗能大，这在商业领域是不划算的，因此，燃气干衣机应运而生，其通过燃烧燃气来进行制热，能显著提高效率，并降低能源消耗量，为商户节约更多的成本。
然而，燃气干衣机由于需要对燃气进行控制，其管路要求较高，通常情况下都是独立设置，并且洗衣房通常情况下不同类型的衣物需要放置在不同的燃气干衣机内，这就使得即使商户选择大型干衣机，也需要设置多台，这必然会造成洗衣房面积的浪费，增加运营成本。
相应的，本领域需要一种新的设备来解决现有燃气干衣机造成的洗衣房运营成本增加的问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有燃气干衣机造成的洗衣房运营成本增加的问题，本发明提供了一种双干衣滚筒的燃气干衣机，其特征在于，包括壳体以及设置在所述壳体内的相邻排布的第一干衣滚筒和第二干衣滚筒、与所述第一干衣滚筒匹配的第一燃气室以及与所述第二干衣滚筒匹配的第二燃气室，所述燃气干衣机还包括燃气供应管路，所述燃气供应管路包括进气管路、三通接 头、第一出气管路和第二出气管路，所述进气管路一端与外部燃气连通，另一端与所述三通接头连通，所述第一出气管路一端与所述三通接头连通，另一端与所述第一燃气室连通，所述第二出气管路一端与所述三通接头连通，另一端与所述第二燃气室连通。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述进气管路、所述第一出气管路和所述第二出气管路均为硬管，所述进气管路、所述第一出气管路和所述第二出气管路与所述三通接头的连接方式均为密封回转连通。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述三通接头包括三通接头本体和第一连接构件，所述三通接头本体包括设置于内部相互连通的三通通道以及设置于所述三通通道的端部的第一接头，所述第一连接构件设有第一通孔，所述第一连接构件靠近所述第一接头的一端设有环形凸起/环形凹槽中的一种，相应地所述第一接头与所述第一连接构件相对的位置设有环形凸起/环形凹槽中的另一种；所述第一连接构件与所述第一接头连接时，所述环形凸起与所述环形凹槽实现可自转地卡接，在所述第一连接构件与所述第一接头之间还设有密封圈，所述第一通孔远离所述三通接头本体的一端还设置有螺纹孔，以使所述进气管路、所述第一出气管路或所述第二出气管路通过螺纹与所述三通通道连通。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述第一连接构件还可以替换为第二连接构件，相应地所述三通接头本体还包括设置于所述三通通道的端部的第二接头，所述第二接头上设置有阶梯孔，在所述阶梯孔上设有内螺纹，所述第二连接构件内部设有第二通孔，在所述第二连接构件的外侧设有外螺纹，与所述第二连接结构连接的所述进气管路、所述第一出气管路或所述第二出气管路的端部带有外侧凸起。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述第二通孔的直径与所述三通通道的直径相同，所述第二通孔的直径大于等于所述燃气供应管路的外径，所述第二通孔的直径小于所述外侧凸起的直径。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述第一出气管路上和所述第二出气管路上还设置有电磁阀。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，在所述第一出气管路和所述第二出气管路的出气端还设置有喷嘴。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述喷嘴的连接方式为可拆卸连接。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述第一出气管路和所述第二出气管路均被拆分成两段管路，两段管路之间的连接方式均为密封回转连通。
在上述双干衣滚筒的燃气干衣机的优选技术方案中，所述进气管路、所述第一出气管路和所述第二出气管路的连接接口处均设置有密封胶。
本领域人员能够理解的是，在本发明的技术方案中，双干衣滚筒的燃气干衣机包括壳体以及设置在壳体内的相邻排布的第一干衣滚筒和第二干衣滚筒、与第一干衣滚筒匹配的第一燃气室以及与第二干衣滚筒匹配的第二燃气室，燃气干衣机还包括燃气供应管路，燃气供应管路包括进气管路、三通接头、第一出气管路和第二出气管路，进气管路一端与外部燃气连通，另一端与三通接头连通，第一出气管路一端与三通接头连通，另一端与第一燃气室连通，第二出气管路一端与三通接头连通，另一端与第二燃气室连通。
通过上述设置方式，使得本发明的燃气干衣机成为双筒均为烘干筒的干衣机，由于双筒结构的设置，相较于两台燃气干衣机的占地面积明显缩小。并且，为了能实现更加高效地烘干，使两个滚筒能完成不同品类物件的烘干，本发明放弃采用一个燃气室燃烧后的热气分别通入两个滚筒的结构设计(此设计一方面由于具有热气分流造成更大的能源损失，另一方面两个滚筒的热气的通入量之和是与燃气室产生的热气量大致相当的，这就使得单个燃气室的燃气输出量要同时受到两个滚筒内所需燃气的能量的制约，控制起来更困难，再一方面，双筒内如果衣物不同，是不能够使用相同温度的热气进行烘干的，这使得双筒只能烘干一种衣物)，转而采用双燃气室搭配双筒的设计，实现了双干衣滚筒的燃气干衣机能够实现不同衣物材质的同时烘干运行，并且烘干效率也大大提升。

此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
首先参照图1和图2，对本发明的双干衣滚筒的燃气干衣机进行详细描述。其中，图1为本发明的双干衣滚筒的燃气干衣机的整体结构示意图，图2为本发明的双干衣滚筒的燃气干衣机的燃气供应管路的结构示意图。
如图1和图2所示，为解决现有的燃气干衣机造成的洗衣房运营成本增加问题，本发明的双干衣滚筒的燃气干衣机包括壳体1以及设置在壳体1内的相邻排布的第一干衣滚筒2和第二干衣滚筒4、与第一干衣滚筒2匹配的第一燃气室3以及与第二干衣滚筒4匹配的第二燃气室5，燃气干衣机还包括燃气供应管路6，燃气供应管路6包括进气管路61、三通接头64、第一出气管路62和第二出气管路63，进气管路61一端与外部燃气连通，另一端与三通接头64连通，第一出气管路62一端与三通接头64连通，另一端与第一燃气室3连通，第二出气管路63一端与三通接头64连通，另一端与第二燃气室5连通。
上述设置方式的优点在于：本发明的燃气干衣机为双筒均为烘干筒的干衣机，由于双筒结构的设置，相较于两台燃气干衣机的占地面积明显缩小。并且，为了能实现更加高效地烘干，使两个滚筒能完成不同品类物件的烘干，本发明放弃采用一个燃气室燃烧后的热气分别通入两个滚筒的结构设计(此设计一方面由于具有热气分流造 成更大的能源损失，另一方面两个滚筒的热气的通入量之和是与燃气室产生的热气量大致相当的，这就使得单个燃气室的燃气输出量要同时受到两个滚筒内所需燃气的能量的制约，控制起来更困难，再一方面，双筒内如果衣物不同，是不能够使用相同温度的热气进行烘干的，这使得双筒只能烘干一种衣物)，转而采用双燃气室搭配双筒的设计，实现了双干衣滚筒的燃气干衣机能够实现不同衣物材质的同时烘干，并且烘干效率也大大提升。通过减少占地、增加烘干效率、实现不同滚筒的独立烘干控制，进而降低洗衣房的运营成本。
下面进一步参照图1至图3，对本发明的双干衣滚筒的燃气干衣机进行详细描述。
如图2和图3所示，在一种可能的实施方式中，进气管路61、第一出气管路62和第二出气管路63均为硬管，进气管路61、第一出气管路62和第二出气管路63与三通接头64的连接方式均为密封回转连通。
对于燃气的控制，虽然双燃烧室具有如上文所述的优势，在减少了热气的运行路径的情况下(不需要进行分流，直接进入干衣滚筒)，增加了燃气的供应长度，为了确保燃气供应安全，本发明采用燃气专用的硬质管路，例如钢管等结构，然而这带来了另一个问题，洗衣机内部结构集中且复杂，并且后续在内部结构调整中可能会对管路进行轻微调整，统一的硬质管路在调节和产品组装过程中由于难以调整，会极大地增加前期产品生产、转运成本以及后期结构调整成本、维护成本。有鉴于此，本发明的进气管路61、第一出气管路62和第二出气管路63在采用硬质管路的同时，还使得三个管路与三通接头64的连接方式均为密封回转连通，这就使得前期生产过程中，操作人员能够根据洗衣机内部实际结构进行轻微的转动调整，使内部结构布局更合理，增加了三通接头64的设计也使得整体硬质管路无需制作成一个管路结合，方便拆卸转运，便于更换零部件。在后期产品线调整过程中，内部结构的轻微改动也可以通过回转管路来实现更好地布局，一举多得。
上面已经阐述了进气管路61、第一出气管路62和第二出气管路63与三通接头64的连接方式均为密封回转连通，但由于燃气管路的密封等要求较高，为实现管路的密封回转连通，还需要特殊且 稳定的密封回转结构才能升任，下面列举本发明所提出的两种密封回转结构。
如图2和图3所示，在一种可能的实施方式中，三通接头64包括三通接头本体641和第一连接构件642，三通接头本体641包括设置于内部相互连通的三通通道6411以及设置于三通通道6411的端部的第一接头6412，第一连接构件642设有第一通孔6421，第一连接构件642靠近第一接头6412的一端设有环形凸起6422，相应地第一接头6412与第一连接构件642相对的位置设有环形凹槽64121；第一连接构件642与第一接头6412连接时，环形凸起6422与环形凹槽64121实现可自转地卡接(为了更好地体现结构，环形凸起6422与环形凹槽64121并未贴合，但本领域技术人员知晓其在实际过程中应当是贴合密封的)，在第一连接构件642与第一接头6412之间还设有密封圈6423，第一通孔6421远离三通接头本体641的一端还设置有螺纹孔64211，以使进气管路61、第一出气管路62或第二出气管路63通过螺纹611与三通通道6411连通。
上述设置方式的优点在于：本发明的第一种连接方式结构简单且密封严密，通过环形凹槽64121与环形凸起6422的物理刚性卡接，具有较大的结合力，再结合内部多个密封圈6423的设计，能够实现偶尔性的转动的情况下不泄露燃气，从而在密封性能与可旋转能力之间找到了一个平衡，能实现装配所需的旋转，但旋转能力不强，相应地由于旋转能力不强，补偿了密封性能，使其仍然具备较高的密封能力，保证了干衣燃气机的安全。
如图2和图3所示，在另一种可能的实施方式中，第一连接构件642还可以替换为第二连接构件643，相应地三通接头本体641还包括设置于三通通道6411的端部的第二接头6413，第二接头6413上设置有阶梯孔64131，在阶梯孔64131上设有内螺纹641311，第二连接构件643内部设有第二通孔6431，在第二连接构件643的外侧设有外螺纹6432，与第二连接结构连接的进气管路61、第一出气管路62或第二出气管路63的端部带有外侧凸起621，内螺纹641311与外螺纹6432配合，并将外侧凸起621夹在中间。进一步地，第二通孔6431的直径与三通通道6411的直径相同，第二通孔6431的直径大于等于燃气供应管路6的外径，第二通孔6431的直径小于外侧凸起621的直径。
上述设置方式的优点在于：本发明的第二种连接方式同样实现了结构简单且密封严密，通过拧动第二连接结构即可使环形管路上的外侧凸起621被施加较大的挤压力，从而避免了燃气的外泄，另外，管路的螺纹与第二连接结构的螺纹连接本身还起到了第二重防泄漏的目的，即使在拧松第二连接结构以实现旋转管路时，燃气依然无法泄露。此种方案相较于第一种方案，由于具有双重防漏，并且只有在松动情况下才能实现旋转，密封强度更强，但在旋转时需要先松开第二连接构件643一部分才能实现旋转，便利性能有一点降低，但安全性能更强。
由于第一种方案与第二种方案各有利弊，但均实现了管路的强力密封，因此，可以通过其组合使用，进而更进一步地发挥各自的优势，例如，如图3所示，在进气管路61的一端，由于其需要与外部连通，在本发明的双干衣滚筒的燃气干衣机进行实地安装时，是需要转动的，因此选择便利性更强的第一种方案，而在本发明的双干衣滚筒的燃气干衣机的内部的第一出气管路62和第二出气管路63，在更多时候是装配过程中进行的调整，在调整完毕后，用户安装过程中干衣机的内部是不能移动的，因此，三通阀与第一出气管路62、第二出气管路63的连接处选择了第二种方案，通过两种方案的结合组合使用，使本发明的双干衣滚筒的燃气干衣机安装便利的同时，达到了最优的防漏安全性能。
上文已经描述完成三通阀处的连接方式，为了使燃气供应管路6更易调节，本发明还将第一出气管路62和第二出气管路63拆分成两段管路，两段管路之间的连接方式均为密封回转连通，从而使得可旋转部位达到了五处(图2中虚线椭圆标注的五处)，其回转连通结构可参考第一种方案或第二种方案。除此之外，第一出气管路62上和第二出气管路63上还设置有电磁阀65，以实现更有效地燃气流量和流速控制。在第一出气管路62和第二出气管路63的出气端还设置有喷嘴66，喷嘴66的连接方式为可拆卸连接，维修更换更为便捷。进气管路61、第一出气管路62和第二出气管路63的连接接口处均设置有密封胶，以实现更好地密封，确保安全。
综上所述，本发明整体以可调节为目的，尽可能地实现在可调节的情况下的最优密封方案组合，以确保双干衣滚筒的燃气干衣机的安全性能。在本发明的整体结构下，燃气干衣机的占地面积缩小， 并且能够分别对双筒实施不同工作状态(不同温度、湿度等)的控制，进而更有利于商业使用，从而使产品在细化领域具有更强地经济优势以及竞争力。
需要说明的是，上述实施方式仅仅用来阐述本发明的原理，并非旨在与限制本发明的保护范围，在不偏离本发明原理的条件下，本领域技术人员能够对上述结构进行调整，以便本发明能够应用于更加具体的应用场景。
例如，在一种可替换的实施方式中，三通阀显然可以至采用同样的一种方案进行密封，以实现制造加工更加便利，这些都不偏离本发明的原理，因此都将落入本发明的保护范围之内。
例如，在另一种可替换的实施方式中，第一连接结构设置有环形凸起6422，第一接头6412设置有环形凹槽64121的结构显然可以相反设置，或者设置卡扣与圆环卡槽的连接方式等，这些都不偏离本发明的原理，因此都将落入本发明的保护范围之内。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
