背景技术
冰箱冷藏室在使用过程中，由于长时间密封，冰箱内会产生大量的气味，当这些气味混杂时会产生异味，用户难以接受，所以越来越多的净味技术在冰箱上进行使用。
目前，冰箱行业内多采用等离子净味技术。等离子净味技术是一种利用高压电离空气产生高能离子对空气进行净化、除味和灭菌的技术。
但是，在现有技术中的等离子净味技术产生的等离子数量少，净味效果差。
发明内容
本公开内容提供一种净化装置及冰箱，旨在至少能够在一定程度上解决等离子净味技术产生的等离子数量少，净味效果差的技术问题。
在本公开的一个方面，提供了一种净化装置，其可以包括：第一放电电极，开设有网孔；第二放电电极，与所述第一放电电极相对设置，所述第二放电电极与所述第一放电电极相对的表面上设置有丝电极，所述第二放电电极与所述第一放电电极相背的表面上设置有针电极；多孔绝缘介质，设置在所述第一放电电极和所述第二放电电极之间。
在一些实施方案中，所述多孔绝缘介质包括蜂窝陶瓷。
在一些实施方案中，所述针电极包括并列设置的若干放电针尖。
在一些实施方案中，所述针电极包括多排并列设置的放电针尖组，所述放电针尖组包括若干放电针尖，每两个相邻的所述放电针尖组的若干放电针尖相互交错。
在一些实施方案中，所述多孔绝缘介质上涂覆有催化介质。
在一些实施方案中，所述第一放电电极与所述多孔绝缘介质之间的距离为1-5mm。
在一些实施方案中，所述第二放电电极包括：至少两根并列设置的安装条；所述安装条与所述第一放电电极相对的表面上设置有所述丝电极，所述安装条与所述第一放电电极相背的表面上设置有所述针电极。
在一些实施方案中，所述第二放电电极还包括：框体，至少两根所述安装条的两端固定于框体上。
在一些实施方案中，所述丝电极通过PCB板印刷铜丝的方式设置在所述安装条上。
在一些实施方案中，所述丝电极包括铜丝、钨丝、银丝中的一种或多种。
在一些实施方案中，所述针电极为镀银针电极、镀金针电极、镀锌针电极中的一种或多种。
在一些实施方案中，所述净化装置还包括：高压电源和用于容纳所述高压电源、所述第一放电电极、所述第二放电电极和所述多孔绝缘介质的箱体，所述高压电源与第一放电电极、丝电极及针电极连接。
在一些实施方案中，所述箱体包括：固定盒和设置于所述固定盒的相对两端的底盖和上盖；所述第一放电电极和所述多孔绝缘介质设置在所述固定盒内，所述高压电源和所述第二放电电极设置于所述底盖上。
在一些实施方案中，所述底盖上固定设置有分隔所述第二放电电极和所述高压电源的分隔板。

在一些实施方案中，所述冰箱包括：制冷风机；所述净化装置固定设置在所述制冷风机的回风口处。
在采用依据本公开的净化装置和冰箱的情况下，由于第二放电电极与第一放电电极相对设置，第一放电电极和第二放电电极之间设置有多孔绝缘 介质，因此在第二放电电极与第一放电电极之间形成了离子场。空气进入离子场内时，第一放电电极、多孔绝缘介质和第二放电电极进行介质阻挡放电，产生等离子，对空气中的异味分子进行降解。由于第二放电电极与第一放电电极相对的表面上设置有丝电极，因此在空气通过多孔绝缘介质到达丝电极处时，丝电极可以进行电晕放电，从而产生等离子，可以对空气中的异味分子进行降解。另外，由于在第二放电电极与第一放电电极相背的表面上设置有针电极，因此空气通过第二放电电极到达针电极处时，针电极可以进行电晕放电，从而产生等离子，对空气中的异味分子进行降解。通过介质阻挡放电与电晕放电两种放电形式，可以高速地产生大量等离子，对异味分子进行降解，净味效果好。

下面结合附图并参考具体实施例描述本公开。
在本公开的一个方面，提供了一种净化装置，旨在至少能够在一定程度上解决等离子净味技术产生的等离子数量少，净味效果差的技术问题。
图1为依据本公开的一些实施例的净化装置的结构示意图，图2为依据本公开的一些实施例的第二放电电极的结构示意图。结合图1及图2，依据本公开的一些实施例的净化装置可以包括：第一放电电极10、第二放电电极20及多孔绝缘介质30。第一放电电极10开设有网孔101。第二放电电极20与第一放电电极10相对设置，第二放电电极20与第一放电电极10相对的表面上设置有丝电极40，第二放电电极20与第一放电电极10相背的表面上设 置有针电极50。多孔绝缘介质30设置在第一放电电极10和第二放电电极20之间。
在一些实施例中，由于第一放电电极10开设有网孔101，因此可以通过网孔101通风。又由于第二放电电极20与第一放电电极10相对设置，并且第一放电电极10和第二放电电极20之间设置有多孔绝缘介质，因此在第二放电电极20与第一放电电极10之间形成了离子场。当空气进入离子场内时，第一放电电极10、多孔绝缘介质30和第二放电电极20进行介质阻挡放电，产生等离子，对空气中的异味分子进行降解。由于第二放电电极20与第一放电电极10相对的表面上设置有丝电极40，因此当空气通过多孔绝缘介质30到达丝电极40处时，丝电极40可以进行电晕放电，产生等离子，对空气中的异味分子进行降解。此外，由于第二放电电极20与第一放电电极10相背的表面上设置有针电极50，因此空气通过第二放电电极20到达针电极50处，针电极50可以进行电晕放电，产生等离子，对空气中的异味分子进行降解。通过介质阻挡放电与电晕放电两种放电形式，可以高速地产生大量等离子，对异味分子进行降解，净味效果好。
结合图1，第一放电电极10太薄会造成电极过脆，使用过程中易被折断，导致损坏，无法使用，而第一放电电极10太厚则会造成成本较高，因此，在一些实施例中第一放电电极10的厚度为1-3mm，优选厚度为1mm。在一些实施方式中，第一放电电极10的材质可以为304不锈钢，304不锈钢是不锈钢中常见的一种材质，密度为7.93g/cm3，业内也叫做18/8不锈钢。耐高温800℃，具有加工性能好，韧性高的特点。当然，在其它实施方式中，第一放电电极10的材质也可以为铜合金、铝合金等金属材质中的一种或多种制成。
结合图1，在一些实施例中，第一放电电极10由连接框架102及金属网103组成，金属网103固定设置在连接框架102内，通过连接框架102支撑金属网103。金属网103上开设有网孔101，空气通过网孔101进入第二放电电极20与第一放电电极10之间形成的离子场内。在一些实施方式中，金属网103的布孔率大于60％，保证净味效果。
结合图1，在一些实施例中，网孔101的孔径可以为0-20mm，优选地孔径为10mm，保证空气可以顺畅进入第二放电电极20与第一放电电极10 之间形成的离子场内。在一些实施方式中，网孔101的形状可以为圆形，当然，在其它实施方式中，网孔101的形状也可以为矩形等形状。
结合图1，在一些实施例中，多孔绝缘介质30包括蜂窝陶瓷，蜂窝陶瓷的化学稳定性好，耐酸碱及有机溶剂，具有极好的耐急热急冷性能，工作温度可高达1000℃，其抗菌性能好，不易被细菌降解，不易堵塞且易再生，具有较强的结构稳定性，孔径分布狭窄，渗透率高，而且其无毒，尤其适用于食品和药物的处理。蜂窝陶瓷是由相等孔径的通孔组成的蜂窝状结构，便于空气的通过，蜂窝陶瓷的形状可以为圆形、长方形、六边形或其它形状。
由于异味分子在高压的作用下，长链的异味分子裂解成短链分子，但是，当离开等离子电场时，短链异味分子与之再聚合生成难分解的大分子，从而降低了除味的效果。因此，在一些实施例中采用蜂窝陶瓷，当空气到达蜂窝陶瓷处时，空气穿过蜂窝陶瓷的通孔，能增大异味分子在第二放电电极20与第一放电电极10之间形成的离子场内的滞留时间及滞留面积，让异味分子及有害细菌等物质在离子电场内充分与活性物质接触并反应，最终被分解为无害无味的CO 2及H 2O，进而达到快速、高效的杀菌净味。
在一些实施例中，多孔绝缘介质30上涂覆有催化介质。通过在多孔绝缘介质30上涂覆催化介质，可作为异味分子吸附和催化分解的反应位点，进一步地延长异味分子在多孔绝缘介质30处的停留时间，加快对异味的去除。在一些实施方式中，催化介质是以铜锰基为主、过渡金属为辅的催化剂。
在一些实施方式中，可以通过金属氧化物和造孔剂及粘土进行复合煅烧，使催化介质与蜂窝陶瓷成为一体，通过蜂窝陶瓷负载催化介质，蜂窝陶瓷的表层和内部有高孔隙，均可作为异味气体吸附和催化分解的反应位点，延长异味分子在蜂窝陶瓷处的停留时间。也可以使蜂窝陶瓷内部具备催化介质，当蜂窝陶瓷外表面的催化介质损坏时，蜂窝陶瓷内的催化介质可以继续延长异味分子在蜂窝陶瓷处的停留时间。在其它实施方式中，可以先制备蜂窝陶瓷基体，将蜂窝陶瓷基体浸入催化介质溶液内，然后对蜂窝陶瓷基体进行煅烧，提高催化介质在蜂窝陶瓷表面的结合强度，保证催化介质牢靠的附着在蜂窝陶瓷的表面，通过催化介质可以延长异味分子在蜂窝陶瓷处的停留时间。
在一些实施方式中，当空气到达多孔绝缘介质30处时，空气中包含大量的高能电子、正负离子、激发态粒子和具有强氧化性的自由基，这类高活性物种吸附到催化介质的活性中心上，两者产生协同催化效应，将异味分子快速催化氧化为CO 2和水。
如果第一放电电极10与多孔绝缘介质30之间的距离太近，会导致放电过于强烈，会产生大量的臭氧，臭氧浓度过高无法在冰箱内进行使用，如果第一放电电极10与多孔绝缘介质30之间的距离太远，又会导致产生的低温等离子体数量较少，影响了净味的效果，因此，在一些实施方式中，第一放电电极10与多孔绝缘介质30之间的距离为1-5mm，优选地为3mm，使第一放电电极10放电不强烈，不会产生大量臭氧，同时，产生大量的低温等离子体，保证净味的效果。
结合图1及图2，在一些实施例中，针电极50包括并列设置的若干放电针尖501。具体地，第二放电电极20与第一放电电极10相背的表面上开设有若干连接孔，放电针尖501嵌入连接孔内，使放电针尖501与第二放电电极20连接为一体，保证放电针尖501与第二放电电极20之间的连接强度。同时，若干放电针尖501串联，形成电晕放电。在一些实施方式中，若干放电针尖501等间距均匀间隔嵌入第二放电电极20与第一放电电极10相背的表面上，保证放电时，可以快速的产生大量的等离子，对异味分子进行降解。
图3为依据本公开的一些实施例的针电极的布置示意图。如图3所示，所述针电极50可以包括多排并列设置的放电针尖组，放电针尖组包括若干放电针尖501，每两个相邻的放电针尖组的若干放电针尖501相互交错，可以增大覆盖面积。当空气通过针电极50时，使针电极50产生的等离子与空气充分接触，对异味分子进行降解，保证净味效果。在一些实施方式中，每一个放电针尖组的若干放电针尖501均等间距均匀间隔嵌入第二放电电极20与第一放电电极10相背的表面上，这样能够保证放电时，可以快速的产生大量的等离子，对异味分子进行降解。在一些实施方式中，每一个放电针尖组的放电针尖501的数目为0-5个，优选地数目为3个。
在一些实施例中，放电针尖501的材质可以为铜针、钨针、银针等中的一种或者多种。在一个实施方式中，放电针尖501的材质为铜针，造价低， 易获取，同时放电效果好。
在一些实施例中，针电极50为镀银针电极、镀金针电极、镀锌针电极中的一种或多种，可以增加放电量，产生更多的离子。在一个实施方式中，针电极50为镀银针电极，即在针电极50的放电针尖501的表面上镀一层银，一方面可以增加放电针尖501的针尖强度，另一方面可以增加放电量，产生更多的离子。
在一些实施例中，放电针尖501的长度为3～12mm，优选地长度为8mm，保证放电针尖501可以快速的产生大量的等离子，对异味分子进行降解。
如果针尖曲率半径过大则会造成放电方式从电晕放电过渡到火花放电，放电剧烈不适合实际应用，而针尖曲率半径越小，起始电晕放电所需电压越小，放电电流越大，因此，放电针尖501的针尖曲率半径小于200μm，保证放电针尖501进行电晕放电，可以快速地产生大量的等离子，对异味分子进行降解。
在一些实施例中，丝电极40包括铜丝，通过铜丝进行电晕放电，同时，铜丝、第一放电电极10和多孔绝缘介质30进行介质阻挡放电，产生等离子，对空气中的异味分子进行降解。
在一些实施例中，铜丝的直径1-5mm，优选地直径为3mm，保证电极强度好，放电性能佳。
在一些实施例中，丝电极40采用PCB板(Printed Circuit Board，印制电路板)印刷铜丝等方式制备，生产方便，结构强度高，保证丝电极40的使用寿命。
由于铜丝造价低，易获取，可以降低生产成本，因此在一些实施方式中丝电极40采用铜丝。当然，在其它实施方式中，丝电极40也可以为钨丝、银丝等中的一种或多种。
结合图1及图2，第二放电电极20可以包括：至少两根并列设置的安装条201。
在一些实施例中，安装条201与第一放电电极10相对的表面上设置有丝电极40。丝电极40采用PCB板印刷的方式设置在安装条201上，生产方便，结构强度高，保证丝电极40的使用寿命。安装条201与第一放电电极10 相背的表面上设置有针电极50。安装条201与第一放电电极10相背的表面上开设有连接孔，针电极50嵌入连接孔内，使放电针尖501与安装条201连接为一体，保证针电极50与安装条201之间的连接强度。
结合图1及图2，在一些实施例中，第二放电电极20还包括框体202。至少两根安装条201的两端固定于框体202上。在一些实施方式中，至少两根安装条201可与框体202一体成型，保证连接牢靠，当然，在其它实施方式中，至少两根安装条201的两端可通过螺栓固定于框体202上，便于拆装。
在一些实施方式中，每两根相邻的安装条201之间有间隙，形成第一通槽203，安装条201的侧部与框体202之间有间隙，形成第二通槽204。空气可通过第一通槽203及第二通槽204到达针电极50处，针电极50处的等离子对空气中的异味分子进行降解。
结合图1，净化装置还可以包括：高压电源60和用于容纳高压电源60、第一放电电极10、第二放电电极20和多孔绝缘介质30的箱体70。
结合图1，在一些实施例中，高压电源60与第一放电电极10、丝电极40及针电极50连接。因此，高压电源60可以向第一放电电极10、丝电极40及针电极50供电，使第二放电电极20与第一放电电极10之间形成离子场，空气进入离子场内，第一放电电极10、多孔绝缘介质30和第二放电电极20进行介质阻挡放电，产生等离子，对空气中的异味分子进行降解。空气通过多孔绝缘介质30到达丝电极40处，丝电极40可以进行电晕放电，产生等离子，对空气中的异味分子进行降解。空气通过第二放电电极20到达针电极50处，针电极50可以进行电晕放电，产生等离子，对空气中的异味分子进行降解。通过介质阻挡放电与电晕放电两种放电形式，可以高速地产生大量等离子，对异味分子进行降解，净味效果好。
在一些实施方式中，高压电源60可以利用脉冲、振荡电器将低电压12V升至高压，将高压连接到第一放电电极10、丝电极40及针电极50上。高压电源60的高压电压采用12V输入，保证了在冰箱内使用的安全性。
结合图1，在一些实施例中，箱体70可以包括：固定盒701和设置于固定盒701的相对两端的底盖702和上盖703，通过底盖702和上盖703封闭固定盒701的两端，使固定盒701内形成空腔，用于容纳高压电源60、第一 放电电极10、第二放电电极20和多孔绝缘介质30。
结合图1，在一些实施例中，第一放电电极10和多孔绝缘介质30可以设置在固定盒701内，通过固定盒701支撑第一放电电极10和多孔绝缘介质30。固定盒701的内壁上可以固定设置有若干限位板704，每两个相邻的限位板704之间有间距，形成限位槽。第一放电电极10和多孔绝缘介质30的周面上可以均固定设置有插件，通过插件插入限位槽内，使第一放电电极10和多孔绝缘介质30设置在固定盒701内，通过限位槽对第一放电电极10和多孔绝缘介质30进行限位，避免第一放电电极10和多孔绝缘介质30在固定盒701内晃动，保证使用安全。此外，限位槽的宽度与插件的宽度相匹配，进一步地避免第一放电电极10和多孔绝缘介质30在固定盒701内晃动，保证使用安全。在一些实施方式中，插件可以为嵌入块。
结合图1，在一些实施例中，高压电源60和第二放电电极20可以设置于底盖702上，通过底盖702支撑高压电源60和第二放电电极20。

结合图1，在一些实施例中，当将高压电源60放入第二容纳腔内，并使高压电源60与第一放电电极10、丝电极40及针电极50连接时，可以向第二容纳腔内注入密封胶，将高压电源60完全密封在第二容纳腔内，从而进一步地保证第一放电电极10、多孔绝缘介质30及第二放电电极20使用的安全性。在一些实施方式中，密封胶可以为树脂胶。
在一些实施例中，固定盒701、底盖702和上盖703的材质可以均采用阻燃材料，阻燃等级为V0级别，保证使用的安全性。固定盒701、底盖702和上盖703的材质可以为ABS塑料，ABS塑料是丙烯腈(A)、丁二烯(B)、苯乙烯(S)三种单体的三元共聚物，它综合了三种组分的性能，其中丙烯腈具有 高的硬度和强度、耐热性和耐腐蚀性；丁二烯具有抗冲击性和韧性；苯乙烯具有表面高光泽性、易着色性和易加工性，上述三组分的特性使ABS塑料成为一种“质坚、性韧、刚性大”的综合性能良好的热塑性塑料。当然，在其它实施方式中，固定盒701、底盖702和上盖703的材质也可以为PP(polypropylene，聚丙烯)材料，聚丙烯是丙烯通过加聚反应而成的聚合物，系白色蜡状材料，外观透明而轻。化学式为(C 3H 6) n，密度为0.89～0.91g/cm 3，熔点189℃，在155℃左右软化，使用温度范围为-30～140℃，在80℃以下能耐酸、碱、盐液及多种有机溶剂的腐蚀。

在一些实施方式中，在上盖703的周面上固定可以设置有若干凸块707，在固定盒701的周面上开设有若干凹槽708，凸块707可嵌入相对应的凹槽708，通过凹槽708对凸块707进行定位，便于卡扣705卡入安装槽706内。此外，安装槽706开设在凸起707上，卡扣705固定设置在凹槽708内。当要将上盖703安装到固定盒701上时，使凸起707对准对应的凹槽708，凸块707嵌入相对应的凹槽708内，同时，使卡扣705卡入安装槽706内，即可实现上盖703与固定盒701的连接，当要将上盖703由固定盒701上取下时，使卡扣705由安装槽706内取出，凸块707与相对应的凹槽708分离，即可实现上盖703与固定盒701的分离，便于拆装。
当然，在其它实施方式中，在固定盒701的周面上可以固定设置有若干凸块，在上盖703的周面上开设有若干凹槽，凸块可嵌入相对应的凹槽，通过凹槽对凸块进行定位，便于卡扣705卡入安装槽706内。此外，安装槽706开设在凸起上，卡扣705固定设置在凹槽内。当要将上盖703安装到固定盒701上时，使凸起对准对应的凹槽，凸块嵌入相对应的凹槽内，同时，使卡扣705卡入安装槽706内，即可实现上盖703与固定盒701的连接，当要将上盖703由固定盒701上取下时，使卡扣705由安装槽706内取出，凸块 与相对应的凹槽分离，即可实现上盖703与固定盒701的分离，便于拆装。
在一些实施方式中，凹槽708的形状与凸块707的形状相匹配，凹槽708的尺寸与凸块707的尺寸相匹配，使凸块701可以完全嵌入凹槽708内，保证上盖703与固定盒701连接牢靠。
在本公开的另一方面，提供了一种冰箱，该冰箱采用了所述净化装置，该净化装置的具体结构参照上述实施例，由于净化装置采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
图4为依据本公开的一些实施例的冰箱的结构示意图，结合图4，所述冰箱可以包括制冷风机90。净化装置可以固定设置在制冷风机90的回风口901处。即：净化装置的箱体70固定设置在制冷风机90的回风口901处，其中，箱体70的上盖703设置在制冷风机90的回风口901。因此，制冷风机90的产生的风可以通过上盖703进入固定盒701内，利用制冷风机90产生的风将产生的带电的高能离子吹向第一放电电极10、多孔绝缘介质30、第二放电电极20、丝电极40及针电极50，空气中的异味分子会附着在多孔绝缘介质30上，第二放电电极20与第一放电电极10之间形成离子场，空气进入离子场内，第一放电电极10、多孔绝缘介质30和第二放电电极20进行介质阻挡放电，产生等离子，对空气中的异味分子进行降解。空气还通过多孔绝缘介质30到达丝电极40处，丝电极40可以进行电晕放电，产生等离子，对空气中的异味分子进行降解。空气还通过第二放电电极20到达针电极50处，针电极50可以进行电晕放电，产生等离子，对空气中的异味分子进行降解。通过介质阻挡放电与电晕放电两种放电形式，可以高速地产生大量等离子，对异味分子进行降解，净味效果好。带电的高能离子进一步地对空气进行净化和除味，加快异味的去除，实现循环净化，无需额外风机，实现无风机自净化，成本低，效果好。
