当上次抽气完成时间小于等于第二预设保压时长阈值且大于第三预设保压时长阈值,控制指示灯603为第三工作状态,以提示用户可抽气;
当上次抽气完成时间小于第三预设保压时长阈值,控制指示灯603为第四工作状态,以提示用户无需抽气。
当上次抽气完成时间大于第一预设保压时长阈值,说明在该储物盒400上次抽气后,储物盒400的使用时长已经很长,储物空间410已经几乎泄压完全,储物空间410的压力余量已完全不能满足真空储存条件,此时需要立即控制真空泵302开启,同时指示灯603为第一工作状态,以提示用户正在抽气。当上次抽气完成时间小于等于第一预设保压时长阈值且大于第二预设保压时长阈值,说明在该储物盒400上次抽气后,该储物盒400的使用时长较长,此时需要抽气但可以不立即抽气。当上次抽气完成时间小于等于第二预设保压时长阈值且大于第三预设保压时长阈值,说明在该储物盒400上次抽气后,该储物盒400的使用时长中等,此时该储物盒400仍可以继续使用,可以抽气也可以不抽气。当上次抽气完成时间小于第三预设保压时长阈值,说明在该储物盒400上次抽气后,该储物盒400的使用时长还很短,无需抽气。
通过引入上次抽气完成时间、第一预设保压时长阈值、第二预设保压时长阈值、第三预设保压时长阈值,涵盖了影响储物空间410的储存效果的几个重要时间节点,使用户的直观获知真空储物装置200的状态,同时指示灯603的工作状态不过多,降低成本和能耗。例如,指示灯603的第一工作状态可以是重复两次闪,第二工作状态可以是慢速闪,第三工作状态可以是快速闪,第四工作状态可以是常亮。指示灯603可以是集成设置在抽气底座300上,例如设置在抽气底座300的面向用户的一侧。指示灯603还可以是远离抽气底座300设置,例如设置在冰箱100的门体102的显示屏处。又或者,可以在抽气底座300上设置指示灯603,同时在门体102的显示屏上设置指示灯603图标。
在一些实施例中,本发明实施例的真空储物装置200设置于冰箱100 内;当上次抽气完成时间小于等于第一预设保压时长阈值且大于第二预设保压时长阈值,控制方法还包括:
判断冰箱100的门体102的关闭时间是否大于预设关门时长阈值;
若是,控制真空泵302开启,开始抽气。
在存在需要抽气的储物盒400时,当门体102的关闭时间超过预设关门时长阈值,说明用户短时间内不会再拿取/存放储物盒400,这个时候可以控制真空泵302开启,开始抽气,以保证所有储物盒400的储存效果。门体102的关闭时间可以是通过设置门体检测装置604来感应门体开关的关闭时间来实现。
图8是图3所示的真空储物装置200的控制方法的一详细流程示意图。本发明实施例的真空储物装置200的控制方法包括以下步骤:
S202:检测是否有储物盒400被放入放置槽311处。当步骤S202的判断结果为是,执行步骤S204。
S204:获取储物盒400的上次抽气完成时间、第一预设保压时长阈值、第二预设保压时长阈值、第三预设保压时长阈值。
S206:比较上次抽气完成时间、第一预设保压时长阈值、第二预设保压时长阈值的大小、第三预设保压时长阈值。依照比较结果不同,执行步骤S208、步骤S210、步骤S212或步骤S214。
S208:当上次抽气完成时间大于第一预设保压时长阈值,控制真空泵302开启,同时控制指示灯603为第一工作状态,以提示用户正在抽气。
S210:当上次抽气完成时间小于等于第一预设保压时长阈值且大于第二预设保压时长阈值,控制指示灯603为第二工作状态,以提示用户需要抽气。在一段时间后,执行步骤S216和S218。

S216:判断冰箱100的门体102的关闭时间是否大于预设关门时长阈值。当步骤S216的判断结果为是,执行步骤S218。
S218:控制真空泵302开启,开始抽气。
如图4所示,在放置槽311处还设置有磁敏开关307,储物盒400的底壁对应磁敏开关307设置有磁体405。磁体405可以为块状磁铁。步骤S202中,检测是否有储物盒400被放入放置槽311处的步骤包括:
检测是否有磁敏开关307被触发;
若是,确定有储物盒400被放入放置槽311处。
在一些实施例中,本发明实施例的真空储物装置200的抽气底座300上设置有按键开关606,按键开关606与真空泵302相连,用于接收用户的开启指令。本发明实施例的真空储物装置200的控制方法还包括:当接收到用户的开启指令,控制真空泵302开启,开始抽气。即通过用户手动控制真空泵302的开关。当接收到用户的开启指令,控制真空泵302开启,同时控制指示灯603为第一工作状态,以提示用户正在抽气。
在另一些实施例中,本发明实施例的真空储物装置200的储物盒400的底部设置有连通储物空间410的气压指示柱601,抽气底座300上对应气压指示柱601的位置处设置有压力传感器602。当检测到有储物盒400被放入放置槽311处,本发明实施例的真空储物装置200的控制方法还包括:获取压力传感器的压力值,当压力传感器的压力值小于预设压力阈值,控制真空泵302开启,开始抽气。气压指示柱601与储物空间410连通,气压指示柱601受储物空间410内部的气压的大小不同而上下变形,由此在当储物盒400放置在放置槽311处时会使得气压指示柱601对压力传感器602的压力不同,从而可以依照压力传感器602的压力值的不同来确定储物空间410的气压的不同。当压力传感器的压力值小于预设压力阈值,说明储物空间410已经几乎泄压完全,储物空间 410已完全不能满足真空储存条件,需要立即开启真空泵302来抽气。也就是说,当检测到压力传感器的压力值小于预设压力阈值,控制真空泵302开启,同时控制指示灯603为第一工作状态,以提示用户正在抽气。
本发明实施例的真空储物装置200的储物盒400可拆卸地与抽气底座300相固定。如图3和图4所示,储物盒400包括盒体406和盖体500,盒体406包括内盒体401和外盒体402,其中内盒体401内限定出储物空间410;外盒体402套设于内盒体401外且与内盒体401之间具有间隙403,外盒体402上形成抽气口420,真空泵302依次经第一抽气口310、抽气口420、间隙403抽出储物空间410内的部分或全部气体。通过将储物盒400设置成包括内盒体401和外盒体402,通过将外盒体402套设于内盒体401外且与内盒体401之间具有间隙403,在外盒体402上形成抽气口420,使得真空泵302依次经第一抽气口310、抽气口420、间隙403抽出储物空间410内的部分或全部气体,避免出现储物空间410内的食材掉落而堵塞抽气口420。盖体500可配置成与外盒体402可拆卸地密封固定,从而开闭储物空间410。
如图4所示,外盒体402的底部设置有连通储物空间410的气压指示柱601,抽气底座300上对应气压指示柱601的位置处设置有压力传感器602。具体地,外盒体402的底壁的***区域向上凸起形成容纳气压指示柱601的空间,在该凸起部分的顶部开设有通孔421,气压指示柱601的顶端对应通孔421设置。气压指示柱601可以是弹性变形件,储物空间410内部的气压不同,气压指示柱601的底端向上或向下变形。
在一些实施例中,本发明实施例的抽气底座300上形成有多个放置槽311,每个放置槽311分别对应一个储物盒400,真空泵302的数量为一个;控制方法还包括:
获取抽气底座300上的所有储物盒400分别对应的预设理想抽气时长;
计算多个预设理想抽气时长的和,得到总理想抽气时长;
判断真空泵302的开启时间是否大于等于总理想抽气时长;
若是,控制真空泵302关停。
以图3为例,抽气底座300上形成有三个放置槽311,每个放置槽311分别对应一个储物盒400,共可以放置三个储物盒400。三个储物盒400的结构可以相同,也可以不同,因此其对应的预设理想抽气时长可以相同,也可以不同。通过计算多个预设理想抽气时长的和,得到总理想抽气时长,基于该总理想抽气时长来控制真空泵302的停止,可以保证所有储物盒400的抽气完全。
在一些实施例中,本发明实施例的抽气底座300还包括:抽气盒304,扣设于第一抽气口310的下方,抽气盒304上开设有第二抽气口340以与真空泵302相连,且抽气盒304内设置有超压泄气阀345;当真空泵302的开启时间小于总理想抽气时长,控制方法还包括:
判断超压泄气阀345是否有动作;
当超压泄气阀345有动作,控制真空泵302关停。
当真空泵302的开启时间大于等于总理想抽气时长,说明所有储物盒400的抽气均已完成。如果真空泵302的开启时间小于总理想抽气时长,则判断超压泄气阀345是否有泄压动作。如果超压泄气阀345有泄压动作,说明所有储物盒400的抽气已经完成,不需要再抽气;如果超压泄气阀345没有泄压动作,说明至少一个储物盒400的抽气未完成,需要继续抽气。超压泄气阀345是否有动作可以通过设置动作检测装置605来实现。
本发明实施例的抽气底座300的抽气盒304设置于座体301内并扣设于第一抽气口310的下方,抽气盒304上开设有第二抽气口340;真空泵302与第二抽气口340经抽气管路(图中未示出)相连。通过设置抽气盒304,可以使得真空泵302与第一抽气口310的连接更易实现。如图5所示,本发明实施例的抽气底座300的抽气盒304的底壁上开设 有超压泄气口342;超压泄气阀345包括设置在抽气盒304内的第二弹簧343和密封垫344,其中密封垫344设置于超压泄气口342处,第二弹簧343的一端抵靠座体301的顶壁内侧,另一端抵靠密封垫344。通过在抽气盒304的底壁上设置超压泄气口342,可以保护真空储物装置200的各部分结构及元器件,控制气压稳定,避免储物盒400抽气时所遇到的负压过大问题。具体地,当抽气盒304内的气压小于额定气压时,第二弹簧343受外部大气压会连带着密封垫344向上方移动,超压泄气口342打开,使得抽气盒304内部与外部空气联通,抽气盒304内部气压不再下降而稳定在额定气压,也就避免了储物盒400出现抽气负压过大问题。当抽气底座300有多个第一抽气口310时,抽气盒304的数量可以为一个,也可以为多个。超压泄气阀345的数量可以为一个,也可以为多个。
图9是图3所示的真空储物装置200的控制方法的另一详细流程示意图。本发明实施例的真空储物装置200的控制方法包括以下步骤:
S302:是否接收到用户的开启指令。当步骤S302的判断结果为是,执行步骤S304。
S304:控制真空泵302开启,开始抽气。
S306:获取抽气底座300上的所有储物盒400分别对应的预设理想抽气时长。
S308:计算多个预设理想抽气时长的和,得到总理想抽气时长。
S310:判断真空泵302的开启时间是否大于等于总理想抽气时长。当步骤S310的判断结果为是,执行步骤S314。当步骤S310的判断结果为否,执行步骤S312。
S312:判断超压泄气阀345是否有动作。当步骤S312的判断结果为是,执行步骤S314。
S314:控制真空泵302关停。
本发明实施例的真空储物装置200的控制方法中,通过获取抽气底 座300上的所有储物盒400分别对应的预设理想抽气时长,计算多个预设理想抽气时长的和得到总理想抽气时长,当真空泵302的开启时间小于总理想抽气时长,判断超压泄气阀345是否有动作,且在当超压泄气阀345有动作时,控制真空泵302关停,控制逻辑简单,容易操作,控制效率高,可以在保证抽气完全的同时避免抽气过度,节约能耗。
下面参考图3和图4,对本发明实施例的真空储物装置200的结构进行进一步说明。
抽气底座300上通常形成有多个放置槽311,每个放置槽311处分别形成有第一抽气口310,真空泵302的数量可以为一个,每个储物盒400内限定出储物空间410且形成有抽气口420,真空泵302依次经第一抽气口310、抽气口420抽出储物空间410内的部分或全部空气,使得同一抽气底座300可以适用多种储物盒400,适用范围更广,且可以方便地向储物盒400内存取食材,提升用户使用体验;通过在抽气底座300内集成一个真空泵302,实现对多个储物盒400的同时抽气,使得抽气部件的构成简单。
本发明实施例的储物盒400的外盒体402的底壁上开设抽气口420。本发明实施例的储物盒400还包括:盒体抽气开关404,设置于抽气口420处,其中盒体抽气开关404为弹性件,并配置成:真空泵302开启,盒体抽气开关404受吸力向下移动以与抽气口420之间形成抽气通道;抽气完成,盒体抽气开关404向上恢复形变并封闭抽气口420。通过设置盒体抽气开关404,可以使得在抽气完成后,储物盒400的抽气口420可以保持密封,用户可以将储物盒400继续放置在抽气底座300上,也可以是将储物盒400放入冰箱100的其他空间,或者将储物盒400放置在冰箱100外部,储物盒400依然可以保持真空状态,使得真空储物装置200具有多种应用方式。具体地,盒体抽气开关404可以具有竖直部(图中未标号)、多个第一水平部(图中未标号)和第二水平部(图中未标号),其中盒体抽气开关404的竖直部贯穿抽气口420设置且外径小于 抽气口420的内径,其位于外盒体402的内部的一端沿其周向间隔设置多个第一水平部,位于外盒体402的外部的一端设置第二水平部。当真空泵302打开,盒体抽气开关404整体向下移动,盒体抽气开关404的竖直部与抽气口420之间形成抽气通道,抽气口420被打开;当抽气完成后,由于抽气底座300中的负压消失,储物盒400中的负压会使第二水平部紧紧贴服在外盒体402上,起到密封作用。
本发明实施例的真空储物装置200的抽气底座300的顶壁上开设第一抽气口310。抽气底座300还包括:底座抽气开关303,设置于第一抽气口310处,并配置成:储物盒400放置至第一抽气口310处,底座抽气开关303受储物盒400的重力作用向下移动并与第一抽气口310之间形成抽气通道;自抽气底座300移除储物盒400,底座抽气开关303向上移动并封闭第一抽气口310。如图4所示,抽气底座300包括座体301,在座体301的顶壁上开设有第一抽气口310。本发明实施例的抽气底座300通过将底座抽气开关303配置成在储物盒400放置至第一抽气口310处时,基于储物盒400的重力作用来与第一抽气口310之间形成抽气通道,而在移除储物盒400后,底座抽气开关303向上移动来封闭第一抽气口310,使得抽气底座300的第一抽气口310的打开和封闭结构十分巧妙,且第一抽气口310的打开和封闭均与储物盒400的放置相关联,可以避免出现未放置储物盒400时,第一抽气口310暴露而导致颗粒物等杂物进入抽气底座300的问题,可以长时间保持抽气底座300的内部清洁度。
具体地,本发明实施例的抽气底座300的底座抽气开关303包括:阀体331、第一弹簧332和第一密封圈333;其中阀体331具有水平部(图中未标号)和自水平部向下延伸的竖直部(图中未标号),阀体331的竖直部贯穿第一抽气口310设置,外径小于第一抽气口310的内径且下部形成有环形槽(图中未标号);第一弹簧332套设于阀体331的竖直部外且夹设于阀体331的水平部和抽气底座300的顶壁之间;第一密封圈333 套设于环形槽内且外径大于第一抽气口310的内径。通过将底座抽气开关303设置成包括阀体331、第一弹簧332和第一密封圈333,使得底座抽气开关303的结构容易配置,且成本低。当将储物盒400放置于抽气底座300内时,底座抽气开关303的阀体331在受储物盒400的重力作用下向下移动时,第一弹簧332被压缩,第一密封圈333向下移动,第一抽气口310被打开,竖直部的外径小于第一抽气口310的内径使得在竖直部与第一抽气口310之间形成抽气通道;当将储物盒400自抽气底座300移出时,第一弹簧332向上恢复形变,第一密封圈333向上移动,封堵第一抽气口310与竖直部之间的缝隙,实现关闭第一抽气口310。
在本实施例的描述中,需要理解的是,对真空储物装置200,术语“上”、“下”、“前”、“后”、“左”、“右”等指示的方位或置关系参考附图2所示的方位或位置关系。同时这仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对发明的限制。
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。
