根据下文结合附图对本发明具体实施例的详细描述,本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解,这些附图未必是按比例绘制的。附图中:
图1是根据本发明一个实施例的冰箱的结构示意图;
图2是图1所示冰箱中的自动开关门装置的示意图;
图3是根据本发明一个实施例的冰箱的示意性主视图;
图4是根据本发明一个实施例的冰箱的示意性侧视图。
本发明实施例提供了一种冰箱。图1是根据本发明一个实施例的冰箱的结构示意图;图2是图1所示冰箱中的自动开关门装置的示意图。
如图1所示,冰箱包括箱体100、抽屉组件200、自动开关门装置300。箱体100的前侧敞开以形成开口,以用于容纳抽屉组件200,抽屉组件200可前后推拉地安装于箱体100。具体为,抽屉组件200包括门体210以及安装于门体210后侧的抽屉220,抽屉220可前后推拉地安装于箱体100内。抽屉220与箱体100的内壁之间可通过滑轨组件连接,滑轨组件在现有技术中非常常见,在此不再介绍其结构。在抽屉组件200处于完全关闭状态(即无法继续后移)时,门体210封闭箱体100前侧的开口。自动开关门装置300安装于箱体200,配置成受控地驱动抽屉组件200前移开门或后移关门,即配置成带动门体210打开或关闭。在一些替代性实施例中,门体210也可为冰箱的其他结构的门体,如冷藏室的门体,可转动地安装于箱体。
图2示意了一种可选的自动开关门装置。自动开关门装置300包括至少一个带传动机构340和一个电机310。每个带传动机构340包括两个齿形带轮341、一个同步带342以及一个连接件343。其中,两个齿形带轮341前后间隔设置。两个齿形带轮341分别可转动地安装于箱体100的内壁,其转动轴均沿冰箱的横向方向(用户朝向冰箱时,用户的左右方向即冰箱的横向方向)。同步带342张紧在两个齿形带轮341上。换言之,同步带342为环圈状,紧套在两个齿形带轮341上。齿形带轮341与传统带轮的区别在于齿形带轮341上设置有啮合齿,与之配合地,同步带342上也设置有带齿,以便与齿形带轮341啮合。因为设置了齿啮合结构,使得传动更加精确,基本实现同步传动。连接件343固定在同步带342上,且与抽屉组件200直接或 间接地固定。例如,可使连接件343固定于与抽屉220直接相连的滑轨上。
电机310安装于箱体100的侧壁,配置成直接或间接地驱动一个齿形带轮341转动,使齿形带轮341带动同步带342移动,从而使同步带342通过连接件343带动抽屉组件200移动。为实现抽屉组件200的开门和关门,电机310可受控地正转和反转。
带传动机构340的数量可为一个,可将该带传动机构340的两个齿形带轮341安装于抽屉220的横向一侧或者下方。也可使带传动机构340的数量为两个,两个带传动机构340的齿形带轮341分别安装于抽屉220的横向两侧,这样使得抽屉组件200两侧均被驱动,平衡性更好。两个带传动机构340之间可连接有同步传动轴,使得两个传动机构之间能够同步移动,且这样仅需设置一个电机即可。
因一般的电机的转速均较快,需要设计减速机构。例如,可使电机310通过蜗轮蜗杆机构驱动齿形带轮341转动,以实现减速效果。具体为,设置一个涡轮330和一个蜗杆320。涡轮330与一个齿形带轮341同轴地相连,两者可为各自为独立零件再进行连接,也可为一个整体件。一个蜗杆320与涡轮330配合,与电机310的转轴连接,以便电机310通过驱动蜗杆320转动,以带动涡轮330转动,进而带动齿形带轮341转动。
图3是根据本发明一个实施例的冰箱的示意性主视图;图4是根据本发明一个实施例的冰箱的示意性侧视图。在本发明的一些实施例中,冰箱还包括第一障碍物检测装置、第二障碍物检测装置和控制装置。第一障碍物检测装置、第二障碍物检测装置和自动开关门装置300均与控制装置电连接。
第一障碍物检测装置安装于门体210,配置成在门体210打开时,检测门体210的前侧是否存在障碍物,以在门体210前侧存在障碍物时,使自动开关门装置300停止打开门体210。也就是说,冰箱在门体210打开的过程中,启动第一障碍物检测装置,当第一障碍物检测装置检测到门体210前侧具有障碍物时,将信号发送给控制装置,控制装置控制自动开关门装置300的电机310停止转动。可在门体210前侧具有障碍物,如突然走过的小孩,门体210自动停止,防止撞伤小孩,也可防止门体210自身结构的破坏。
第二障碍物检测装置可配置成在门体210关闭时,检测门体210的后侧是否存在障碍物,以在门体210后侧存在障碍物时,使自动开关门装置300停止关闭门体210。第二障碍物检测装置可安装于门体210或箱体100。冰 箱在门体210关闭的过程中,启动第二障碍物检测装置,当第二障碍物检测装置检测到门体210后侧具有障碍物时,将信号发送给控制装置,控制装置控制自动开关门装置300的电机310停止转动。可在门体210后侧具有障碍物,如取放物品的手,门体210自动停止,防止夹手,同样也可防止门体210自身结构的破坏。
当然,若在门体210打开的过程中,第一障碍物检测装置未检测到障碍物,则自动开关门装置300可使门体210运动到完全打开状态。若在门体210关闭的过程中,第二障碍物检测装置未检测到障碍物,则自动开关门装置300可使门体210运动到完全关闭状态。
在本发明的一些实施例中,如图3和图4所示,第一障碍物检测装置包括至少一个距离感应板400。门体210包括主体211和设置于主体211前侧的面板212。每个距离感应板400采用接近感应,设置于主体211与面板212之间,且与面板212接触抵靠。进一步地,距离感应板400为多个,如4个,设置于门体210的下部,且沿冰箱的横向方向依次间隔设置。面板212可为玻璃板。在该实施例中,通过采用接近感应的距离感应板400作为第一障碍物检测装置,可设置于门体210的面板212后侧,且面板212上无需开孔,可保证面板212的强度和美观度。
在本发明的一些实施例中,第二障碍物检测装置为力检测装置,配置成检测自动开关门装置300的输出力,以在输出力大于或等于预设值时,使自动开关门装置300停止关闭门体210。具体地,第二障碍物检测装置用于检测电机310的输出力,若输出力超过预定值,则认为门体210在关闭的过程中碰到障碍物了,需停止关门。
本发明还提供了一种冰箱的控制方法。本发明的冰箱的控制方法可包括如下步骤:
获取开门指令或关门指令。控制装置响应用户发送的控制指令,判断该控制指令是否为开门指令或关门指令。例如,可以是在冰箱上设置一与控制装置信号连接的开关,该开关可为机械开关,优选为触控开关。在抽屉组件200处于关闭静态(即处于关闭状态且并未移动)下,用户触发该开关时,该开关将发出开门指令。在抽屉组件200处于完全打开的静态下被用户触发时,开关将发出关门指令。或者,还可利用实体遥控、语音声控等其他方式发出开门指令或关门指令。在本发明的一些实施例中,也可利用距离感应板 400检测信号,以生成开门指令或关门指令。当冰箱在关门状态下,冰箱通过距离感应板400检测到有用户的脚靠近时,向控制装置发送开门指令。在冰箱门体210处于打开状态时,用户用脚去触碰门体210,向控制装置发送关门指令。当然也可采用其他装置,如专门设置的感应开关,来检测用于的脚的状态,生成开门指令或关门指令。
控制自动开关门装置300驱动抽屉前移开门或后移关门。也就是说,获取到开门指令时,控制自动开关门装置300驱动抽屉前移开门。获取到关门指令时,控制自动开关门装置300驱动抽屉后移关门。以及,第一障碍物检测装置或第二障碍物检测装置进行检测。
判断第一障碍物检测装置或第二障碍物检测装置是否检测到障碍物。当判断结果为是时,控制自动开关门装置300停止运行,以使抽屉停止移动;当判断结果为否时,使得抽屉仍正常开门或关门。
至此,本领域技术人员应认识到,虽然本文已详尽示出和描述了本发明的多个示例性实施例,但是,在不脱离本发明精神和范围的情况下,仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此,本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
