Description

冰箱及冰箱的冷藏室的湿度控制方法 技术领域
本发明涉及制冷技术领域, 特别涉及一种水箱及水箱的冷藏室的湿度的控制方法。 背景技术
传统的水箱通常利用风机实现冷气强制对流循环来间接冷却食品。 由于冷气在水箱 内进行循环, 箱内食品内的水份不断被冷气带走并在蒸发器上结霜, 因此传统水箱的冷 藏室内的最高湿度不超过 75%RH, 平均湿度仅能维持在 50%RH左右甚至更低。
大多数水果蔬菜其干耗 (重量损失) 超过 5 %时, 就会出现枯萎等鲜度下降的明显 象征。 特别是水果, 当于耗达 5%以后就不可能恢复原状。 果蔬的水分蒸发, 一方面是 由于呼吸作用, 散发出一部分水分; 另一方面是储藏环境的空气湿度过低, 容易导致食 品脱水风干, 引起果蔬枯萎, 降低或失去食用价值。 因此, 为了提高水果蔬菜的保鲜储 藏效果, 通常要求冷藏室内的平均湿度保持在 80 % -90 %左右。
传统水箱的冷藏室内的湿度偏低, 达不到水果蔬菜的高保湿保鲜储藏要求, 容易导 致水果蔬菜易脱水风干, 降低储藏时间和食用价值。 发明内容
本发明旨在至少解决上述技术问题之一。 为此, 本发明的一个目的在于提出一种水 箱的冷藏室的湿度的控制方法。
本发明的另一目的在于提出一种具有加湿成本低、 加湿状态可控且具有高保湿功能 的水箱。

下面参考附图描述根据本发明实施例的水箱。
如图 1所示, 根据本发明实施例的水箱包括: 箱体 1、 门体 2、 压缩机 3、 蒸发器 4、 风机 5、 第一温度传感器 (未示出) 、 第二温度传感器 (未示出) 、 冷藏室保湿模式选 择装置 61和控制器 62。
具体而言, 箱体 1 内可以限定有冷藏室 11和风道 41 , 风道 41通过出风口 412和位 于出风口 412下面的回风口 411与冷藏室 11连通。 在冷藏室 11内可以装配有内饰件, 内饰件可以包括玻璃搁架 12、 门体托盘 13和果菜盒 14。
门体 2可枢转地安装在箱体 1上用于打开和关闭冷藏室 11。门体 2和箱体 1可以通 过铰链 21连接。压缩机 3可以设在位于箱体 1底部的压缩机仓 31内。 蒸发器 4设在风 道 41 内用于对冷藏室 11制冷。 风机 5设在风道 41 内用于将蒸发器 4制冷的空气通过 出风口 412输送到冷藏室 11 内, 以对冷藏室 11制冷。 第一温度传感器(未示出)可以 设在冷藏室 11内, 用于检测冷藏室 11 内的温度。 第二温度传感器(未示出)可以设在 蒸发器 4上用于检测蒸发器 4的温度。
冷藏室保湿模式选择装置 61 用于在高保湿模式和正常保湿模式之间切换冷藏室。 换言之,冷藏室保湿模式选择装置 61用于将冷藏室 11切换到高保湿模式或正常保湿模 式。
控制器 62分别与第一温度传感器、 第二温度传感器、 压缩机 3、 风机 5和冷藏室保 湿模式选择装置 61连接。 当通过模式选择装置 61将冷藏室 11的保湿模式切换到高保 湿模式时,在冷藏室 11内的温度大于等于第一预定温度 Trk时控制器 62启动水箱的压 缩机 3和风机 5以对冷藏室 11进行制冷。在冷藏室 11内的温度小于等于第二预定温度 Trt时控制器 62停止压缩机 3且继续运行风机 5 , 即压缩机 3停止运行, 并使风机 5继 续运行, 同时控制器 62控制对蒸发器 4化霜, 从而通过风机 5将蒸发器 4的化霜水送 到冷藏室 44内, 对冷藏室 44加湿, 由于化霜水通过风机 5输送到冷藏室 11 内, 因此 冷藏室 11内的湿度增大, 即冷藏室 11处于高保湿模式, 在蒸发器 4的温度大于等于第 三预定温度 Trq时, 控制器 62停止风机 5和停止蒸发器 4的化霜。 蒸发器 4的化霜可 以通过任何合适的方式进行, 例如通过控制器 62控制电加热丝对蒸发器 4进行化霜。
当通过模式选择装置 61将冷藏室 11的保湿模式切换到正常湿模式时,在冷藏室 11 内的温度大于等于第一预定温度 Trk时控制器 62启动水箱的压缩机 3和风机 5以对冷 藏室 11进行制冷, 在冷藏室 11 内的温度小于等于第二预定温度 Trt时控制器 62停止 压缩机 3和风机 5。 在正常保湿模式下, 由于没有对蒸发器 4进行化霜, 风机 5无法将 化霜水送入冷藏室 11内, 因此冷藏室 11 内的湿度低于高保湿模式下的湿度。
根据本发明实施例的水箱,在高保湿模式下,冷藏室 11 内的平均湿度可以达到 82% 以上, 最高湿度可以达到 85%。 从而可以满足对冷藏室 11的高保湿要求。
其中第一预定温度 Trk大于第二预定温度 Trt, 且第三预定温度 Trq > 0 °C。
根据本发明实施例的水箱, 用户可以使用冷藏室保湿模式选择装置 61对冷藏室 11 的保湿模式进行选择, 控制器 62根据用户的选择以在高保湿模式和正常保湿模式之间 切换冷藏室 11 , 可以满足对冷藏室内不同的湿度需求, 在高保湿模式下冷藏室 11内的 湿度可以维持在较高的湿度。 在开启正常保湿模式下可以使冷藏室 11 内的湿度处于相 对较低的湿度。 并且, 根据本发明实施例的水箱, 易于实现, 无需对传统水箱的结构进 行复杂的改造, 成本低。
优选地, 第三预定温度 Trq可以为 3 °C。 由此, 可以增加对蒸发器 4的化霜时间, 及对冷藏室 11 的加湿时间。 需要说明的是, 用户可以根据需要自己设定第三温度 Trq 的大小, 以满足相应的对水箱冷藏室的湿度的需求。
如图 1、 图 2所示, 根据本发明的一个实施例, 蒸发器 4具有楔形横截面 (例如蒸 发器 4可以具有三角形或梯形横截面), 蒸发器 4的下端的宽度小于蒸发器 4的上端的 宽度, 且风道 41容纳蒸发器 4的部分具有与蒸发器 4适配的形状, 即风道 41容纳蒸发 器 4的部分的上部的尺寸大于其下部的尺寸。 由此, 釆用楔形的蒸发器 4, 对冷藏室 11 进行制冷, 化霜过程中, 受重力作用, 蒸发器 4的翅片表面的水滴将会越来越多地集中 到蒸发器 4的下部, 水分蒸发同经过其表面的风速关系密切, 在总风量一定的情况下, 风道横截面积小的部位, 风速必然更高。 由于风道 41容纳蒸发器 4的部分的宽度与蒸 发器 4适配, 因此蒸发器 4蒸发化霜水的效率提高, 在增强保湿效果的同时避免通过风 机提速保湿的方式带来的噪音问题。
如图 1、 图 2所示, 根据本发明的一个实施例, 蒸发器 4的下端邻近风道 41的回风 口 411 , 蒸发器 4的上端邻近风道 41的出风口 412。 由此, 风从风道 41的下端的进入 风道 41 , 经过蒸发器 4后从风道 41的上端进入冷藏室 11。 由于蒸发器 4的下端的宽度 较小, 使得流经蒸发器 4下端的风的风速变快, 可以加速蒸发器 4下部的水分蒸发。 因 此, 与通过提高风机 5转速相比, 可以在风机 5的转速不变的情况下, 提高回风口 411 处的风速, 进而提高保湿效果。
如图 2所示, 根据本发明的一个实施例, 蒸发器 4的下部设有吸水材料 90。 吸水材 料 90可以收集储存蒸发器 4上的化霜水, 解决箱体 1 内水分的流失问题。 进一步地, 吸水材料 90可以为多孔硅滤膜或多孔复合纤维。 由此, 在风机 5进行高保湿功能运行 状态下, 能够通过自身的多孔状结构, 扩大了水蒸汽有效蒸发面积, 提高保湿效果。
如图 3所示, 根据本发明的一些实施例, 冷藏室保湿模式选择装置 61 可以为设在 箱体 1上或箱门 2上的保湿模式选择按键 611。 由此, 可以方便用户对冷藏室 11的保 湿模式的选择。
冷藏室保湿模式选择装置 61 可以集成在显控板上, 显控板上还可以设有用于接通 通或断开水箱的电源的水箱开关机按键 613 , 及温度调节按键 612。 由此, 可以方便对 水箱的开关机进行操作及对水箱冷藏室的温度进行调节。
如图 4所示, 根据本发明的一些实施例, 风机 5可以为盒式轴流风机且风机 5的扇 叶 51的自由端一体地设有除霜叶尖 511。 由此, 可以避免风扇的扇叶 51的叶尖 511上 结霜, 提高了风机 5的工作效率。
如图 1所示, 根据本发明的一个实施例, 风机 5的转轴与水平面可以成预定角度设 置。 例如装配时, 风机 5的位置可以设在蒸发器 4的上端并倾斜放置。 由此, 可以减少 风机 5上积存的水对电机造成损坏。 优选地, 风机 5 的转轴与水平面的夹角为可以为
25度。 由此可以方便风机 5 , 特别是扇叶 51上的水流下, 避免了水直接流入风机 5的 电机 (为示出) 内对电机造成损坏。
下面参见图 5-7描述根据本发明实施例的水箱的冷藏室的湿度的控制方法, 如上所 述, 冷藏室 1 1具有高保湿模式和正常保湿模式, 所述控制方法包括以下步骤:
判断水箱的冷藏室 11的保湿模式。 例如, 控制器 62根据通过冷藏室保湿模式选择 装置 61输入的指令判断用户选择的保湿模式。
当冷藏室 11处于高保湿模式时(用户选择高保湿模式) , 控制器 62可以控制第一 温度传感器对冷藏室 1 1内的温度进行检测。 然后, 将检测到的冷藏室 11内的温度与第 一预定温度 Trk进行比较, 在冷藏室 11 内的温度大于等于第一预定温度 Trk时, 控制 器 62启动水箱的压缩机 3和风机 5以对冷藏室 11进行制冷。
在冷藏室 11 内的温度小于等于第二预定温度 Trt时停止压缩机 3且继续运行风机
(使压缩机 3停止工作, 并使风机 5继续工作) , 并对水箱的蒸发器 4化霜, 以通过风 机 5利用蒸发器 4的化霜水对冷藏室 11加湿。 以实现冷藏室 11的高湿度。
控制器 62控制第二温度传感器对蒸发器 4的温度进行检测, 在检测到的蒸发器 4 的温度大于等于第三预定温度 Trq时, 控制器 62停止风机 5和停止蒸发器 4的化霜以 停止利用蒸发器 4的化霜水对冷藏室 11加湿。
当冷藏室 11处于正常保湿模式时, 控制器 62控制第一温度传感器对冷藏室 11的 温度进行检测。 将检测到的冷藏室 11 内的温度与第一预定温度 Trk进行比较, 在冷藏 室 1 1内的温度大于等于所述第一预定温度时 Trk , 控制器 62启动水箱的压缩机 3和风 机 5以对冷藏室 1 1进行制冷。 在冷藏室 1 1内的温度小于等于第二预定温度 Trt时, 停 止压缩机 3和风机 5。
其中第一预定温度 Trk大于第二预定温度 Trt, 且所述第三预定温度 Trq > 0 °C。 根据本发明实施例的水箱的冷藏室的湿度的控制方法, 可以根据具体需求控制水箱 的压缩机和风机的运行以及化霜器的化霜,从而可以实现冷藏室内的不同湿度, 并且易 于实现, 能耗低, 成本低。
优选地, 第三预定温度 Trq为 3 °C。
需要说明的是, 在正常保湿模式下, 风机 5的控制可能有两种方案: 一是风机 5和 压缩机 3同步运行, 当压缩机 3启动时, 风机 5也开始运行, 压缩机 3停机时, 风机 5 也停止运行; 二是风机 5和压缩机 3非同步运行, 当压缩机 3启动时, 风机 5提前或延 时一定时间运行(例如, 一般延时 1-5分钟) , 压缩机 3停机时, 风机 5提前或延时一 定时间停止运行(例如,一般延时 1 -5分钟)。 由于压缩机 3开机期间蒸发器 4在制冷, 因此冷藏室 11 内湿度一直在下降, 压缩机 3停机期间, 由于风机 5的运行时间很短, 蒸发器 4表面各处温度将保持在 0 °C或 0 °C以下, 霜层未融化, 因此冷藏室 1 1内湿度上 升很小。 正常运行期间, 冷藏室 11内的最高湿度通常不超过 65%RH , 平均湿度维持在 50%RH左右甚至更低。 当用户不希望水箱运行在高保湿模式时, 可以关闭此功能, 降 低冷藏室内的湿度。
在本说明书的描述中, 参考术语 "一个实施例" 、 "一些实施例" 、 "示例" 、 "具体示例" 、 或 "一些示例" 等的描述意指结合该实施例或示例描述的具体特征、 结 构、 材料或者特点包含于本发明的至少一个实施例或示例中。 在本说明书中, 对上述术 语的示意性表述不一定指的是相同的实施例或示例。 而且, 描述的具体特征、 结构、 材 料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例, 本领域的普通技术人员可以理解: 在不脱 离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、 修改、 替换和变型, 本发明的范围由权利要求及其等同物限定。
