Description

一种冰箱
本申请要求于2019年5月27日提交中国专利局、申请号为201910447697.X、201920774302.2、201910448238.3、201920773601.4、201910447702.7、201920773590.X、201910447696.5、201920773585.9、201910448237.9、201920774300.3、201910448236.4、201920773589.7、201910447688.0、201920773583.X、201811457088.4，申请名称为“一种冰箱”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于家电领域，特别涉及一种冰箱。
背景技术
近年来，人们的健康意识逐渐提高，对食材保鲜的需求也随之提高，冰箱作为食材存储最常用的家用电器，食材保鲜存储成为冰箱领域亟待解决的技术需求。
目前，针对食材保鲜存储问题，各个厂家推出了不同的保鲜技术。例如，真空保鲜技术，真空状态下，食物变质的条件发生了改变。首先，真空环境，微生物、各种促进酶很难生存，需要长时间才能达到微生物滋生的要求；其次，真空状态下，容器内的氧气大大减少，各种化学反应无法完成，食物不会被氧化，也使得食物可以长期保鲜。
目前冰箱上应用的真空保鲜技术，主要是在冰箱内设置密封抽屉，通过设置在抽屉外的小型真空泵对抽屉进行抽真空处理，使抽屉保持负压状态，实现了抽屉内食材的保鲜。这种保鲜方式具有以下局限性：1.由于抽真空处理需要通过真空泵实现，真空泵会占用冷藏间室部分储藏空间；2.这种保鲜方式需要对抽屉进行密封，否则抽屉内无法形成真空状态，因此，对抽屉的成型以及装配工艺提出了较高的要求；3.这种保鲜方式只能对抽屉内的食材进行保鲜，对于冰箱其他区域的食材则无法起到保鲜作用。
专利申请内容
本申请要解决的技术问题是现有冰箱保鲜效果不理想，进而提出一种成本较低、不占用储藏空间且能够对各个区域食材都进行保鲜的冰箱。
为了解决上述技术问题，本申请公开一种冰箱，包括储藏室以及打开或关闭 所述储藏室的门体，所述门体上设有真空封装装置，所述真空封装装置包括：位置上下对应的上支座与下支座，其中，所述下支座可拆装地连接于所述门体上；所述上支座和/或所述下支座在两者相对的表面上开设开口腔；所述上支座在驱动装置驱动下可向接近或远离所述下支座的方向移动；所述上支座向接近所述下支座的方向移动至所述上支座与所述下支座对接，所述开口腔通过密封部密封形成抽真空区；抽真空组件，所述抽真空组件与所述抽真空区通过管路连通，用于对所述抽真空区进行抽真空或泄压。
本申请的技术方案相对现有技术具有如下技术效果：
本申请的冰箱在门体上设置真空封装装置，其可以对即将放入冰箱的装有食材的储物袋进行真空封装处理；相对现有的真空抽屉来讲，采用本申请的真空封装装置可以对储藏于冰箱各类间室的食材进行抽真空保鲜处理，扩大了保鲜范围；另外，该真空封装装置中的下支座可以从门体拆卸下来；可以方便用户清理抽真空过程中抽入下支座的食物残渣，用户体验好，提高了冰箱的智能化程度。

如图3、图4所示，该冰箱的所述门体200上设有真空封装装置300，真空封装装置300用于对储物袋进行抽真空并塑封处理；该真空封装装置300既可以设置在冷冻门体200A上也可以设置于冷藏门体200B上，由于冷藏门体200B位于上侧，为了符合用户的使用习惯，通常优选设置于冷藏门体200B上。
如图4-图17为所述真空封装装置300的一种实施方式，本实施方式中，如图4所示，所述真空封装装置300包括：下支座310，所述下支座310设有第一开口腔311；上支座320，所述上支座320设有第二开口腔321，所述上支座320 在驱动装置340驱动下可向接近或远离所述下支座310的方向移动，所述上支座320向接近所述下支座310的方向移动到位后，所述第一开口腔311与所述第二开口腔321对接并密封形成抽真空区301。上述真空封装装置300通过控制驱动装置340的自动升降实现下支座310与上支座320的锁紧与解锁，实现了自动真空封装，提高了冰箱的智能化程度。
具体地，为了提高所述抽真空区301的密封性，如图4所示，所述下支座310与所述上支座320相对表面上设置用于密封所述抽真空区301的密封部。具体地，所述下支座310在所述第一开口腔311的外周设有第一密封槽313，所述上支座320在所述第二开口腔321的外周设有第二密封槽323，所述第一密封槽313与所述第二密封槽323的位置相对且内部设有密封圈350。设置在第一密封槽313和第二密封槽323内的两个密封圈350将所述抽真空区301密封在内侧，实现了抽真空区301的可靠密封。
具体地，如图5所示，所述第一开口腔311或所述第二开口腔321内设有限位部，用于限制插接于所述抽真空区301内的储物袋的插入位置，避免储物袋的开口位置伸出所述抽真空区301；具体地，所述限位部为设置于所述第一开口腔311或所述第二开口腔321内的限位筋322，所述限位筋322的高度大于所述所述第一开口腔311或第二开口腔321的深度；所述限位筋322的长度略低于所述所述第一开口腔311或第二开口腔321的长度。用户将储物袋插入所述抽真空区301时，所述限位筋322可阻挡所述储物袋继续向内插入；其他实施方式中，该抽真空区301还可以设置到位检测装置，具体地，可以采用微波传感器或红外传感器，用于检测向所述抽真空区301插入的储物袋的有无，进而向所述控制器发出所述储物袋是否到位信号，控制器可以根据到位信号控制所述真空泵开启。通过设置到位检测装置可以自动检测所述储物袋是否到位，控制器进而自动控制所述真空泵的通断。
所述真空封装装置300还包括抽真空组件330，如图6、图7所示，所述抽真空组件330包括与所述抽真空区301通过管路335连通的真空泵331；所述管路335上还设有压力检测装置332和泄压装置333，其中，压力检测装置332具体为压力传感器，用于在检测到抽真空区301压力；所述泄压装置333具体为电动泄压阀，所述电动泄压阀打开时，对所述抽真空区301进行泄压。用户进行抽 真空封装时，开启真空泵331对所述抽真空区301进行抽真空处理，当所述压力检测装置332检测到抽真空区301的压力达到设定负压值时，控制器控制所述真空泵331停止。通过设置压力传感器可以控制所述抽真空区301的真空度，真空泵331可以根据压力传感器的检测值通断，保证了抽真空效果。在抽真空以及封装操作完成后，通过开启上述电动泄压阀可以自动控制该抽真空区301进行泄压，方便用户取出储物袋。为了避免抽真空区301的异物经过所述管路335进入所述真空泵331，所述管路335上还包括过滤保护装置，其中一种实施方式中，如图8所示，所述过滤保护装置具体为串联在管路335上的过滤容器334，所述过滤容器334的上端设置入口和出口，所述入口与所述抽真空区301通过管路连通，所述出口与所述真空泵331通过管路连通；抽真空区301的异物通过管路335进入所述过滤容器334留存于所述过滤容器334底部，避免异物进入所述真空泵331。为了方便清理所述过滤容器334，更具体地，所述过滤容器334包括具有开口的罐体和可拆卸连接于所述罐体的上盖，所述上盖上设置所述入口和出口，清理时将所述罐体拆下进行清洁即可，避免频繁拆装管路335导致管路335密封性变差的问题。
另一种实施方式中，如图9所示，所述过滤保护装置为设置所述管路335上的过滤网336，具体地，为了方便拆装，所述过滤网336设置在所述上支座320与所述管路335连接位置的通气孔324位置，用户将上支座320移动至最高位置处后，即可从下侧对过滤网336进行拆装或清洁操作。
所述抽真空区301与所述管路335的连接孔可以是一个，当然，为了避免单一连接孔时所述抽真空区301内异物堵塞所述连接孔导致抽真空故障，还可以通过设置两个或两个以上的连接孔分别与所述管路335连接的方式，所述管路335之间并联设置，通过三通或多通连接器后与总管连接；其中压力传感器、电子泄压阀设置在总管上。
如图4所示，所述真空封装装置300还包括相对设置的隔热垫360与加热装置370；用于在抽真空结束后对储物袋进行塑封处理；所述隔热垫360与所述加热装置370位于所述抽真空区301外侧的封装区302内。具体地，所述加热装置370安装于所述上支座320下表面的凹槽内；所述隔热垫360则安装于所述上支座320下支座310上表面的凹槽内；当上支座320移动至与所述下支座310形成 密封的抽真空区301后，封装区302内的隔热垫360抵靠在加热装置370上。抽真空完成后，通过封装区302的加热装置370可以将储物袋快速塑封，根据加热装置370工作设定时长后，控制驱动装置340带动上支座320上移，用户可抽出储物袋完成储物袋的塑封。
更具体地，如图10、图11所示，所述加热装置370包括加热丝371，所述加热丝371下侧设有导热板373，用于扩散所述加热丝371的加热面积使所述储物袋塑封面积增大，塑封牢固。所述加热丝371沿所述上支座320的长度方向延伸并在所述上支座320两侧向上折弯，所述加热丝371延伸至所述上支座320上侧的自由端通过一个绝缘板372固定于所述上支座320上，具体地，所述绝缘板372为绝缘材料制成，且成型为折弯板，包覆于所述加热丝371的外侧，避免加热丝371裸露在外侧。更进一步地，所述加热丝371的两个自由端分别通过弹簧375与通过接线端子374引出的两个导线连接；通过设置弹簧375可以使所述加热丝371始终处于拉紧状态，使加热丝371平整度较高，位于所述加热丝371下侧的导热板373与储物袋接触紧密；避免加热丝371不平整导致个别位置接触不实塑封不上的问题。
上述抽真空塑封装置中，所述驱动装置340可以为电动驱动装置也可以为气压驱动装置；气压驱动装置占用空间较大，因此本实施方式中，所述驱动装置340采用电动驱动装置。具体地，如图7、图12及图13所示，所述驱动装置340包括电机341以及传动机构，所述传动机构用于将所述电机的旋转运动转换为直线运动，所述传动机构的输出端与所述上支座连接。所述传动机构包括固定连接于所述电机输出轴上的第一齿轮342；与所述第一齿轮342啮合的第二齿轮343；与所述第二齿轮343固定连接的第三齿轮344，以及与所述第三齿轮344啮合的输出齿条345，其中，所述输出齿条345下侧设有销孔，所述上支座320与所述输出齿条345通过插接于所述销孔的销轴346连接。经过上述传动机构，所述电机341的转动转换成所述上支座320的上下移动。
具体地，如图7所示，所述上支座320与所述驱动装置340之间设有连接板347，所述连接板347与所述上支座320螺纹连接，且所述连接板347上成型有导向槽3471，所述输出齿条345的下端插接于所述导向槽3471内，所述导向槽3471与所述输出齿条345的下端分别设有长条形的销孔，所述销轴346穿设于 所述导向槽3471与所述输出齿条345的所述销孔内，所述输出齿条345的下端面与所述导向槽3471的槽底具有间隙，所述间隙内设有弹性体348。
如图12所示，初始位置时，所述上支座320位于最高位置；在压合阶段，如图13所示，驱动装置340带动上支座320向下运动，为了保证下支座310与上支座320紧密配合，通常以所述电机341的设定转动行程作为到位判断信号，因此，在所述输出齿条345与所述导向槽3471之间设置弹性体348可以使上支座320下移至与下支座310接触后，所述输出齿条345能够继续向下运动一段距离，使弹性体348被压缩，防止电机341堵转，对电机341起到保护作用，并能使压合力保持稳定。
在抽真空阶段，下支座310与上支座320之间形成的密闭的抽真空区301，由于气压变低，在大气压的作用下，上支座320向下运动，此时，由于长条形销孔的存在可以使所述上支座320下移时，所述输出齿条345保持位置不动，对整个驱动装置340起到保护作用。
为了精确控制所述上支座320的移动位移进而判断所述上支座320是否移动到位使所述抽真空区301形成密封空间；其中实施方式中，所述电机341为步进电机341，通过检测所述步进电机341的转动行程判断所述上支座320是否移动到位。另一种实施方式中，在所述下支座310或所述上支座320上设有微动开关；所述上支座320移动到位后通过触发所述微动开关，所述控制器根据所述微动开关的反馈信号控制所述驱动装置340停止并锁定于当前位置。
所述驱动装置340可以设置为一个，所述输出齿轮位于所述上支座320的中部区域，这种情况容易导致上支座320的边缘区域与下支座310切合不够紧密导致抽真空区301漏气；因此，为了提供抽真空区301的密封性，所述驱动装置340分别设置在所述上支座320的两侧。相应地，所述连接板347设置一个，所述连接板347设有两个所述导向槽3471；两个输出齿条345分别伸入所述导向槽3471内。
具体地，如图6、图7所示，所述驱动装置340以及所述抽真空组件330均安装于位于所述上支座320上侧的安装座305上。所述上支座320上开设有通气孔324，用于与所述抽真空组件330连通。其中，所述安装座305的一侧设有三个腔室，其包括位于中间位置的真空泵安装腔3051，以及位于左右两侧的驱动 装置安装腔3052。为了保持冰箱门体200外表面的整体美观性以及应用真空封装装置300的便利性，如图3所示，所述门体外壳210设有向内凹陷的安装腔211，所述驱动装置340与所述上支座320连接后通过螺钉连接于所述安装座305上，所述抽真空组件330与所述上支座320上的通气孔324连接后安装于所述安装座305上，形成一个组件后，整体通过穿设于所述安装座305两侧支耳上的螺钉安装于所述安装腔211内，各个零部件实现了模块化装配，各个零件不裸露在外表面，装置的整体性较好。
用户应用该真空封装装置300对食品袋进行塑封时，特别是具有粉末状的食品例如面粉等或液体等进行塑封时，在进行抽真空时粉末或液体有可能进入到抽真空区301内，最终积存于下支座310的第一开口腔311内；因此，为了方便用户清理该下支座310内的食物残渣，该下支座310相对所述门体200可拆卸安装。
其中，所述下支座310安装于所述门体200的方式不唯一，本实施例中，如图14A-图14C所示，所述下支座310可从所述门体200的内侧(即具有内胆的一侧)可拆卸地安装于所述门体200上。由于冰箱的门体200必须保证绝热性，因此，所述下支座310朝向所述储藏室100的内侧部分设置保温小门250。其中，如图14C所示，所述门体200上开设连通内外的安装孔201，所述下支座310与保温小门250从所述门体200的内侧插接于所述安装孔201上，同时实现了下支座310的拆卸清洗以及门体200的保温性能。
其中一种实施方式中，如图15所示，所述下支座310与保温小门250一体成型；如图15、图16所示，所述下支座310与保温小门250由具有开口腔结构的第一壳体251和第二壳体252以及设置在第一壳体251和第二壳体252之间绝热件形成。其中，第一壳体251与第二壳体252卡扣连接，所述第一壳体251在远离所述第二壳体252的方向设有延伸臂2511，所述下支座310形成于所述延伸臂2511上，所述第一开口腔311为形成于所述延伸臂2511上侧的开口槽，在所述开口槽的外周设有第一密封槽313。
为了进一步保证该门体200的绝热性，避免通过该安装孔201与所述保温小门250之间的缝隙漏冷，如图15、图16所示，在该保温小门250与所述门体内胆220之间设有小门门封253。具体地，所述第一壳体251在与所述门体内胆220 配合的位置处设有支臂2512，所述支臂2512的尺寸大于所述安装孔201的尺寸。所述支臂2512上设有环绕所述安装孔201的安装槽，所述小门门封253安装于所述安装槽内。
具体地，为了保证该保温小门250可靠地固定于所述门体200上，在所述保温小门250与所述门体内胆220之间设有锁定装置400，所述锁定装置400用于将所述保温小门250锁定或解锁于所述门体200上。

更具体地，所述下支座310通过推弹的方式可拆卸地连接于所述门体200上。其中，如图27、图28所示，所述下支座310与所述门体200的连接面上设置第二推弹开关380，所述第二推弹开关380包括推弹锁381以及锁扣382；所述下支座310的内侧面成型有设置所述锁扣382的凹槽，所述门体200的外表面上固定所述推弹锁381。
如图29A所示，沿门体200垂直方向推压下支座310时，推弹锁381与锁扣382扣合，下支座310安装在门体200上；如图29B所示，再次推压下支座310时，推弹锁381释放锁扣382，使下支座310可拆下移出门体200。用户可以单独清洗下支座310，方便用户操作。
实施例6
本实施例6与实施例5的结构基本相同，区别在于所述下支座310安装于所述门体200的方式。
具体地，本实施方式中，如图30A、图30B所示，所述下支座310从所述门体200的外侧可拆卸地安装于所述门体200上。
更具体地，所述下支座310通过卡接的方式可拆卸地连接于所述门体200上。 所述下支座310与所述门体200上分别成型互相配合的第一卡接部391和第二卡接部392，其中所述第一卡接部391成型于所述下支座310的下表面，具体为折弯钩，所述第二卡接部392固定连接在所述门体200前侧表面。所述下支座310向接近所述门体200方向内移动至第一卡接部391和第二卡接部392配合实现下支座310的安装；拆卸时，向外侧拉动所述下支座310，第一卡接部391和第二卡接部392发生弹性变形使两者脱离，用户可以单独清洗下支座310，方便用户操作。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本申请创造的保护范围之中。
