Description

一种双向开关门装置以及具有该装置的冰箱 技术领域
本发明涉及冰箱制造技术领域，尤其涉及一种双向开关门装置以及具有该装置的冰箱。
背景技术
冰箱是一种保持恒定低温的制冷设备，主要包括箱体、设置在所述箱体内并用以储藏食品的储藏室以及用以封闭所述储藏室的门体，所述门体通过铰链铰接安装在所述箱体上，从而实现打开或者关闭所述储藏室。
目前，市场中流通的冰箱通常被制成只沿预定的方向打开或者关闭门体，例如，以向右打开或者关闭的方式、以向左打开或者关闭的方式。此处，术语“向右打开或者关闭的方式”表示铰链连接到门体的右端使得门体绕着其右端枢转，而术语“向左打开或者关闭的方式”表示铰链连接到门体的左端使得门体绕着其左端枢转。当冰箱被安置在某一地方时，门体只可以沿着预定方向打开或者关闭，如果在门体的打开或者关闭的方向上存在障碍物(例如，墙壁、家用电器等)，则会影响用户的使用。为了便于打开或者关闭冰箱门体，用户通常需要挪动家用电器或者移动冰箱，常常给用户带来不必要的麻烦。此外，单向打开或者关闭的冰箱不能同时满足习惯使用右手的人和习惯使用左手的人。
为了解决上述问题，冰箱生产商又开发出一种可以双向开门的冰箱，该种冰箱是通过在箱体的两侧分别安装铰链来实现的。当用户需要改变开门方式时，将门体从箱体的一侧拆卸下来，然后再安装到箱体的另一侧，然而此种操作工序非一般用户可以完成的，需要专门的维修工来完成，从而使得用户在使用的过程中依然会感觉到很不方便。
鉴于上述问题，有必要提供一种新的双向开关冰箱，以解决上述问题。
发明内容

进一步地，每个所述内卡件还设置有位于其配合部远离其第二枢接部一端的卡持部，当一个所述内卡件的配合部受到相应所述外卡件的第二抵持部抵持时，该内卡件上的卡持部脱离相应所述收容槽，当一个所述内卡件的配合部脱离相应所述外卡件的第二抵持部抵持时，该内卡件上的卡持部伸入相应所述收容槽。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
在本发明的一些实施例中，请参阅图1并结合图2所示，本发明双向开关门装置100用于冰箱，包括壳体10、设置在所述壳体10内的连杆20、设置在所述连杆20两端并与所述连杆20相配合的两个锁定装置30以及用以调节打开方式的调节机构40。
请参阅图3、图4并结合图2所示，所述壳体10包括底壁11、垂直于所述底壁11向外弯折延伸的侧壁12、与所述底壁11相对设置的顶壁13以及设置所述底壁11外侧以供左右拨动的手柄14。所述底壁11、侧壁12以及顶壁13共同构成收容空间15以收容所述连杆20、两个锁定装置30以及调节机构40。所述侧壁12包括前壁121以及与所述前壁121相对设置的后壁122。所述底壁11中间设置有两个挡壁111、枢接轴112以及第二凸伸部113，两个所述挡壁111之间形成限位槽114以收容所述连杆20。所述底壁11的两端还分别设置有外枢接轴孔115、内枢接轴孔116、外安装柱117、外固定柱118以及内固定柱119。所述壳体10两端分别设置有向外开放的收容槽16，所述收容槽16贯穿所述底壁11、顶壁13以及后壁122以便安装在冰箱箱体或者门体上的铰接装置50的轴毂51进出，所述外枢接轴孔115、内枢接轴孔116分别位于所述收容槽16的两侧，在壳体10的长度方向上，所述外枢接轴孔115和所述挡壁111之间的距离大于所述内枢接轴孔116和所述挡壁111之间的距离。所述底壁11中间还设置有安装槽17以安 装所述手柄14。
请参阅2所示，所述连杆20可左右移动，包括设置在所述连杆20中间的配合槽21以及分别设置在所述配合槽21两侧的一对锁定部22。
请参阅5并结合图6、图7以及图8所示，每个所述锁定装置30包括安装在所述壳体10上并相对设置在相应所述收容槽16两侧的第一锁定机构31和第二锁定机构32。每个所述第二锁定机构32位于所述连杆20和相应所述第一锁定机构31之间。每个所述第一锁定机构31包括枢接在所述壳体10上的外卡件311以及固定在所述壳体10和所述外卡件311之间的扭簧312。所述外卡件311大致呈月牙状，其上设置有第一抵持部313、第二抵持部314以及位于两者之间的第一枢接部315。所述第二抵持部314设置有向外凸伸的第一连接部316、与相应所述配合部324相配合并沿所述壳体10厚度方向相对设置的两个抵持臂317以及由两个所述抵持臂317形成的抵持槽318。所述第一枢接部315为枢接轴，安装在所述外枢接轴孔115内。所述扭簧312的一端固定安装在所述外固定柱118上，另一端固定安装在所述第一连接部316上。所述第二锁定机构32包括枢接在所述壳体10上的内卡件321以及固定在壳体10和所述内卡件321之间并对所述内卡件321施力以使得所述内卡件321旋转的弹性元件322。所述内卡件321设置有连接所述弹性元件322的第二连接部323、用以与相应所述第二抵持部314相配合的配合部324、位于两者之间的第二枢接部325以及位于所述配合部324远离所述第二枢接部325一端的卡持部328。所述配合部324上设置有与所述抵持臂317相配合并沿所述壳体10厚度方向设置的两个导引槽326以及形成于两个所述导引槽326之间并与所述抵持槽318相配合的导引块327。所述第二枢接部325为枢接轴，安装在所述内枢接轴孔116内。所述弹性元件323的一端固定安装在所述内固定柱119上，另一端固定安装在所述第二连接部323上。
请参阅图6、图7以及图8所示，当两个所述锁定装置30中的一个锁定装置打开，即所述一个锁定装置中的外卡件311的第一抵持部313在轴毂51的作用下旋转而离开相应收容槽16时，所述一个锁定装置中的外卡件311上的第二抵持部314抵持所述一个锁定装置中的内卡件321上的配合部324以使得内卡件321旋转，所述一个锁定装置中的内卡件321旋转时抵持连杆20的一端以使连杆20在壳体10内移动，同时所述一个锁定装置中的内卡件321的卡持部328脱离相应收容槽16，并使得连杆20另一端抵持另一锁定装置，进而使得所述另一锁定装置保持锁定状态；此时，扭簧312被旋转至一定角度以致扭簧312对第二抵持部314施力以使得第二抵持部314保持抵持配合部324的状态。当所述一个锁定装置中的外卡件311的第二抵持部314在轴毂51的作用下而使得所述一个锁定装置中的外卡件311反向旋转时，所述一个锁定装置中的外卡件311的第一抵持部313和所述一个锁定装置中的内卡件321的卡持部328伸入收容槽16内，并且所述一个锁定装置中的内卡件321在弹性元件322的作用下复位。例如，当轴毂51进入相应收容槽16内以关闭冰箱门体时，轴毂51可对所述一个锁定装置中的外卡件311的第二抵持部314施加作用力以使所述一个锁定装置中的外卡件311反向旋转。
在本发明的一些实施例中，当冰箱左侧的轴毂51进入相应收容槽16内以关闭冰箱 门体时，左侧轴毂51可对双向开关门装置100的左侧锁定装置中的外卡件311的第二抵持部314施加作用力以使左侧锁定装置中的外卡件311沿第一方向旋转，左侧锁定装置中的外卡件311的第一抵持部313转动深入壳体10的左侧收容槽16内，左侧锁定装置中的外卡件311的第二抵持部314转动脱离与内卡件321的配合部324的配合，同时使左侧锁定装置中的扭簧312旋转一定角度以处于扭转状态。左侧锁定装置中的内卡件321在弹性元件322的作用下复位，即左侧锁定装置中的内卡件321的卡持部328伸入收容槽16内。
当冰箱右侧的轴毂51脱离相应收容槽16内以打开冰箱门体时，右侧轴毂51可对双向开关门装置100的右侧锁定装置中的外卡件311的第一抵持部313施加作用力以使右侧锁定装置中的外卡件311沿与第一方向相反的第二方向旋转，右侧锁定装置中的外卡件311的第一抵持部313转动离开右侧收容槽16。右侧锁定装置中的外卡件311上的第二抵持部314抵持右侧锁定装置中的内卡件321上的配合部324以使得内卡件321旋转，右侧锁定装置中的内卡件321旋转时抵持连杆20的一端以使连杆20在壳体10内移动，同时右侧锁定装置中的内卡件321的卡持部328脱离相应收容槽16，并使得连杆20另一端抵持左侧锁定装置，进而使得左侧锁定装置保持锁定状态。右侧锁定装置中的扭簧312在右侧轴毂51开始相对于右侧收容槽16移动时处于扭转状态，右侧扭簧312产生的弹簧力促使右侧锁定装置中的外卡件311转动，待右侧外卡件311的第二抵持部314与右侧内卡件321的配合部324配合后，可使得右侧锁定装置中的第二抵持部314保持抵持右侧锁定装置中的配合部324的状态。
在本实施例中，所述弹性元件322为拉簧，但是在另一实施例中，请参阅图9所示，弹性元件322'为压簧。
请参阅图10并结合图11所示，所述调节机构40用以调节打开方式，包括调节所述连杆20位置的拨动装置41以及维持所述拨动装置41位置不变的维持装置42。所述拨动装置41包括与所述连杆20相配合的拨块411以及设置在所述拨块411两侧用以卡持所述锁定部22的两个卡持机构412。所述拨块411设置有凸伸入所述配合槽21内并与所述配合槽21相配合的配合块4111以及第一凸伸部4112。每个所述卡持机构412包括枢接于所述壳体10上的转杆413以及在所述转杆413推动下可左右滑动的滑杆414。所述转杆413包括与所述拨块411相配合的第一部415、与所述滑杆414相配合的第二部416以及位于两者之间的枢接部417。所述第一部415上设置有与所述第一凸伸部4112相配合的第一滑槽4151。所述第二部416远离所述枢接部417的一端与所述滑杆414的一端枢接在一起，所述滑杆414可绕所述第二部416转动。所述枢接部417为枢接轴孔，枢接安装在所述枢接轴112上。所述滑杆414靠近所述第二部416的一端设置有与所述锁定部22相配合的卡持槽4141以及与所述第二凸伸部113相配合的第二滑槽4142。在本实施例中，所述滑杆414是枢接在所述转杆413上，但是在其它实施例中，所述滑杆414亦可以固定安装在所述转杆413上。所述维持装置42包括固定于所述壳体10上的压簧421、压杆422以及设置在所述拨动装置41上的定位槽423，所述定位槽423位于所述第一部415远离所述枢接部417的一端。所述压杆422的一端固定在所述压簧421 上，另一端固定在所述壳体10上，其上设置有与所述定位槽423相配合的定位块424。
请参阅图11并结合图13以及图14所示，当拨动所述手柄14使得所述定位块424位于所述定位槽423内，所述压簧421对所述压杆422施力以使得所述定位块424抵持所述定位槽423，从而使得所述拨块411在不受外力作用的情况下不会左右移动，从而可以维持所述拨动装置41的位置不变。此时，两个卡持机构412的卡持槽4141均脱离相应锁定部22，两个锁定装置30中的一个锁定装置打开时，该锁定装置抵持连杆20在壳体10内移动，并使得连杆20另一端抵持另一锁定装置，进而使得另一锁定装置保持锁定状态。当拨动所述手柄14使得所述拨块411克服所述维持装置42的作用力运动并使得所述定位块424脱离所述定位槽423时，所述压簧421对所述压杆422施力以使得所述定位块424抵持所述定位槽423的侧缘，从而使得所述拨块411在不受外力作用的情况下不会左右移动，从而可以维持所述拨动装置41的位置不变。此时，拨块411推动连杆20向两个卡持机构412的一卡持机构移动，该卡持机构的转杆413在拨块411的作用下旋转以推动滑杆414向锁定部22运动以使得滑杆414的卡持槽4141卡持锁定部22，从而使得连杆20抵持两个锁定装置30中的一个锁定装置并使该锁定装置保持锁定状态。
图12所示为所述维持装置42的另一实施方式。所述维持装置42'为一具有弹性的弹片，其一端设置有与所述定位槽423相配合的定位块424'。显然，所述维持装置42'亦可以维持所述拨动装置41的位置不变。当然，所述维持装置42还具有许多其它实施方式，于此就不一一举例赘述了。
在本发明的一些实施例中，在打开冰箱门体之前，用户可使拨块411处于中间位置，此时两个卡持机构412的卡持槽4141均脱离相应锁定部22，两个锁定装置30中的任一个锁定装置打开时，该锁定装置可抵持连杆20在壳体10内移动，并使得连杆20另一端抵持另一锁定装置，进而使得另一锁定装置保持锁定状态。例如，用户可向左打开冰箱门体，即可使冰箱右侧的轴毂51脱离相应收容槽16内以向左打开冰箱门体，右侧锁定装置可抵持连杆20在壳体10内向左移动，并使得连杆20左端抵持左侧锁定装置，进而使得左侧锁定装置保持锁定状态。同样地，在拨块411处于中间位置时，用户也可向右打开冰箱门体。
在本发明的一些实施例中，在打开冰箱门体之前，用户可选择打开冰箱门体的方向，若用户需要向左打开冰箱门体，可先使拨块411处于左侧卡持位置。具体地，用户拨动拨块411使其由中间位置或右侧卡持位置向左侧卡持位置移动的过程中，其上的配合块4111向配合槽21的左侧移动并抵持配合槽21的左侧内壁而推动连杆20向左移动，并使得连杆20左端抵持左侧锁定装置，进而使得左侧锁定装置保持锁定状态；且左侧卡持机构的转杆被拨块推动使得左侧滑杆与左侧锁定部相卡持，使左侧锁定装置保持锁定状态；右侧锁定装置可解除对右侧轴毂的锁定。然后，用户向左打开冰箱门体，右侧锁定装置的打开此时不会引起连杆20向左移动。同样地，在打开冰箱门体之前，用户可选择向右打开冰箱门体，可先使拨块411处于右侧卡持位置，然后向右打开冰箱门体。在一些安装位置受限的地方放置具有上述双向开关门装置100的冰箱时，可使拨块411一直处于左侧卡持位置，从而使冰箱门体只能向左打开，以解决右侧开门不便的问题，同时 使左侧锁定装置保持锁定的状态。
在本发明的一些实施例中，用户在放置冰箱时，可根据冰箱的安装位置和使用习惯对双向开关门装置100进行设置。例如，由于安装位置有限，用户只能向右打开冰箱门体，则需要使拨块411处于右侧卡持位置。当用户只能向左打开冰箱门体，则需要使拨块411处于左侧卡持位置。当安装空间充裕，用户可以向右打开冰箱门体，也可向左打开冰箱门体时，则可使拨块411处于中间位置，以方便地向右打开，或向左打开；当安装空间充裕，用户可以向右打开冰箱门体，也可向左打开冰箱门体时，然而用户只希望向右打开冰箱门体或只希望向左打开冰箱门体，则可使拨块411处于相应的卡持位置即可。也就是说，用户可通过拨动拨快411的位置：左侧卡持位置、中间位置、右侧卡持位置，以分别实现右侧开关门(左侧打不开门)、左右开关门(即可以从左侧开关也可以从用侧开关)、左侧开关门(右侧打不开门)的模式。
尽管本实施例中所述双向开关门装置100采用了所述调节机构40，但是，显然，本实施例中所述双向开关门装置100在没有所述调节机构40的情况下亦可以实现双向打开或者关闭。
请参阅图15所示，本发明还提供了一种冰箱200，所述冰箱200包括箱体210、门体220、设置在所述箱体210上的轴毂(未图示)以及设置在所述门体220上的双向开关门装置100，所述双向开关门装置100与所述轴毂相配合以使得将门体220固定安装在箱体210上。在本实施例中，所述双向开关门装置100设置在所述门体220的上侧，但是在其它实施例中，所述双向开关门装置100亦可以设置在所述门体220的下侧。
请参阅图16所示，本发明还提供了另一种冰箱300，所述冰箱300包括箱体310、门体320、设置在所述门体320上的轴毂330以及设置在所述箱体310上的双向开关门装置100，所述双向开关门装置100与所述轴毂330相配合以使得将门体320固定安装在箱体310上。在本实施例中，所述双向开关门装置100设置在箱体310上与门体320上侧相对应的中梁搁板340上，但是在其它实施例中，所述双向开关门装置100亦可以设置在箱体310上与门体320下侧相对应处。
综上所述，由于本发明所述双向开关门装置100可以实现双向打开关闭，从而使得本发明所述冰箱200、300亦可以实现双向打开或者关闭门体，从而可以满足具有不同需求的客户，提高了用户使用满意度。
相较于现有技术，本发明双向开关门装置100可以在不拆卸的情况下，实现双向打开或者关闭，从而可以满足具有不同需求的客户，提高了用户使用满意度。
特别需要指出，对于本领域的普通技术人员来说，在本发明的教导下所作的针对本发明的等效变化，仍应包含在本发明申请专利范围所主张的范围中。
