下面参考图1-图7描述根据本发明实施例的对开门冰箱100。其中，对开门冰箱100可以为风冷冰箱等。
如图1-图3所示，根据本发明第一方面实施例的对开门冰箱100，包括：箱体1、至少一组对开门体2和输风管组件。
具体地，箱体1可以形成为长方体结构，箱体1内具有压缩机仓11。压缩机仓11内设有压缩机3、风机4和冷凝器5，冷凝器5与压缩机3相连，风机4设在压缩机3和冷凝器 5之间，箱体1的前侧设有中梁22。中梁22可以沿对开门冰箱100的高度方向(例如，图1中的上下方向)延伸。
参照图3，压缩机仓11可以位于箱体1的后侧且位于箱体1的下部。由此，可使得对开门冰箱100的重心靠下，提高了对开门冰箱100的稳定性。压缩机仓11上设有可拆卸的盖板(图未示出)，盖板可以通过螺钉或者卡扣连接在箱体1上。由此，便于压缩机3、冷凝器5、风机4等的装配和维修。
压缩机3可以位于风机4的出风侧。风机4可以加快压缩机仓11内空气的流通，提高冷凝器5的冷却速度，且可以降低压缩机3表面的温度，从而减小了压缩机3下次启动时的负荷，降低了对开门冰箱100的整机能耗。
至少一组对开门体2可枢转地设在箱体1上，其中，对开门体2可以为一组或多组。每组对开门体2包括分别设在中梁22的左侧和右侧的两个门体21。例如，在图1和图2的示例中，对开门体2为两组，两组对开门体2可以沿上下方向间隔设置，形成为十字形的对开门。相邻的两组对开门体2之间限定出横梁23。
可选地，对开门体2可以通过铰链等安装在箱体1上，但不限于此。
输风管组件包括彼此连通的进风罩61和出风罩62，进风罩61设在压缩机仓11内，进风罩61位于风机4的出风侧且进风罩61的进风口面向风机4，出风罩62设置在箱体1上并向中梁22出风。具体地，进风罩61和出风罩62可以通过输风管63连通。输风管组件构造成用于将压缩机仓11内的热风吹向中梁22。
可选地，进风罩61的进风口可以正对风机4，由此，可以加大进风罩61内的进风量。
具体地，对开门冰箱100运行时，压缩机3工作时，将制冷剂压缩为高温高压的气态制冷剂，高温高压气态制冷剂进入冷凝器5内冷凝为高压低温(但高于环境温度)的制冷剂液体，经过冷凝器5被风机4送出的风为热风，热风可以从进风罩61的进风口处进入输风管63，并通过出风罩62吹向中梁22。由此，可以提高中梁22的温度且可以加快中梁22处的空气流通，从而可以有效地防止在中梁22上以及对开门体2的相对的侧壁上产生凝露，提高了对开门冰箱100的防凝露效果。
根据本发明实施例的对开门冰箱100，通过在对开门冰箱100上设置输风管组件，将压缩机仓11内的热风吹向中梁22，提高了中梁22的温度且加快了中梁22处的空气流通，从而有效地防止了在中梁22上以及对开门体2的相对的侧壁上产生凝露，提高了对开门冰箱100的防凝露效果。
根据本发明的一些实施例，出风罩62设在中梁22的下方且出风罩62的出风口朝上。参照图2-图3，输送管沿箱体1的底壁延伸至中梁22的下方，从进风罩61进入输送管的风 可以通过出风罩62从下向上吹向中梁22。由此，便于热风从下向上流动，从而可以增大中梁22上的流动风量，有效地提高中梁22的温度、加快中梁22处的空气流通，提高了对开门冰箱100的防凝露效果。此外，对开门冰箱100的压缩机仓11通常设在箱体1的下部，将出风罩62设在中梁22的下方，有利于布置输风管63，便于安装，且有利于减小输风管63的总长度，从而有效地减小了输风管组件的用料，节省了材料成本。
根据本发明的一些实施例，中梁22内部可以预埋防露管，由此可以进一步地提高对开门冰箱100的防凝露效果。
进一步地，进风罩61的进风口处设有挡风阀片611，挡风阀片611在关闭进风口的第一位置和打开进风口的第二位置之间可枢转。
例如，可以根据环境温度和环境湿度将对开门冰箱100的运行工况设定为普通工况和高湿工况。在高湿工况下，湿度较大，中梁22上容易产生凝露，此时可以打开进风口，通过输风管63将热风输送到中梁22上，以提高中梁22的温度、加快中梁22处的空气流通，有效地防止产生凝露。在普通工况下，湿度较小，中梁22上不易产生凝露，此时可以关闭进风口，输风管组件不能将热风输送到中梁22，减小了不必要的热风吹向中梁22侧带来的耗电量损耗。
具体地，挡风阀片611可以通过枢转机构设在进风罩61上，枢转机构包括枢转轴612和与枢转轴612配合的枢转孔613，其中，枢转轴612设在进风罩61和挡风阀片611中的其中一个上，枢转孔613设在进风罩61和挡风阀片611中的另一个上。具体而言，当枢转轴612设在进风罩61上时，枢转孔613可以设在挡风阀片611上，当枢转孔613设在进风罩61上时，枢转轴612可以设在挡风阀片611上。
可选地，枢转轴612设在进风罩61和挡风阀片611中的上述其中一个的上端。
例如，参照图5和图6，枢转轴612设在挡风阀片611上，枢转孔613形成在进风罩61上。挡风阀片611可以形成为长方形的片状结构。枢转轴612形成在挡风阀片611的上端，枢转孔613为两个，分别形成在进风罩61的左侧和右侧，枢转孔613可以形成为圆形的通孔或盲孔。在自然静止条件下，挡风阀片611在重力的作用下自然下垂，此时挡风阀片611可以挡住进风口，进风口处于关闭状态，在吹向挡风阀片611的风足够大时，挡风阀片611可沿风向倾斜一定的角度，吹向挡风阀片611的风量越大，挡风阀片611倾斜的角度越大，进入进风罩61的风量越大。
可选地，挡风阀片611与枢转轴612可以一体成型，工艺简单，加工方便。
具体地，用户可以根据对开门冰箱100的运行工况调节风机4的转速。例如，在普通工况下，可以控制风机4以第一转速运行，在高湿工况下，可以控制风机4以第二转速运行。 其中，第一转速小于第二转速，且当风机4以第一转速运行时，进风罩61内的挡风阀片611不会被吹开或者吹开的幅度较小，进风口近乎处于关闭状态，不会有或者仅有少量的热风被输送到出风罩62，此时可以减小不必要的热风吹向中梁22侧带来的耗电量损耗；当风机4以第二转速运行时，进风罩61内的挡风阀片611会被吹开，进风口处于打开状态，此时有热风被输送到出风罩62，热风从下向上吹向中梁22，此时可以有效地防止在中梁22上产生凝露。
根据本发明的一些实施例，对开门冰箱100上设有温度传感器和湿度传感器。其中，温度传感器可以用于测量环境温度，湿度传感器可以用于测量环境湿度。温度传感器和湿度传感器可以分别为独立的传感器，也可以将温度传感器和湿度传感器集成为一体。
温度传感器和湿度传感器均与对开门冰箱100的主控板电连接，产品制造商可以根据对开门冰箱100的具体规格型号设定对开门冰箱100运行普通工况时的环境温度范围和环境湿度范围、运行高湿工况时的环境温度范围和环境湿度范围。压缩机3启动时，对开门冰箱100根据温度传感器和湿度传感器测定的数据运行普通工况或高湿工况。
具体地，温度传感器和湿度传感器可以设在对开门体2的顶部且位于对开门体2的邻近铰链的一侧。由此，可以准确地测量环境温度和环境湿度且便于安装。
根据本发明实施例的对开门冰箱100的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
根据本发明实施例的对开门冰箱100，可以有效地防止对开门冰箱100在中梁22处产生凝露，提高了对开门冰箱100的能效和可靠性，降低了使用成本。
根据本发明第二方面实施例的对开门冰箱100的控制方法，其中，对开门冰箱100为根据本发明上述第一方面实施例的对开门冰箱100。
具体地，参照图7，对开门冰箱100的控制方法包括以下步骤：
根据环境温度和环境湿度将对开门冰箱100的运行工况设定为普通工况和高湿工况；
压缩机3启动时，检测当前环境温度和环境湿度，并判断对开门冰箱100的运行工况；
当运行工况为普通工况时，进风罩61的进风口关闭；
当运行工况为高湿工况时，进风罩61的进风口打开。
例如，在高湿工况下，湿度较大，中梁22上容易产生凝露，此时打开进风口，通过输风管63可以将热风输送到中梁22上，以提高中梁22的温度、加快中梁22处的空气流通，有效地防止产生凝露。在普通工况下，湿度较小，中梁22上不易产生凝露，此时关闭进风口，输风管组件不能将热风输送到中梁22，减小了不必要的热风吹向中梁22侧带来的耗电量损耗。
根据本发明实施例的对开门冰箱100的控制方法，根据当前环境温度和环境湿度运行不同的运行工况，并根据不同的运行工况控制进风罩61的进风口的关闭，有效地防止了在中梁22上产生凝露，提高了对开门冰箱100的可靠性。
根据本发明的一些实施例，当运行工况为普通工况时，风机4以第一转速运行；当运行工况为高湿工况时，风机4以第二转速运行，其中第一转速小于第二转速。具体地，当风机4以第一转速运行时，进风罩61内的挡风阀片611不会被吹开或者被吹开的幅度较小，进风口处于关闭状态，不会有或者仅有少量的热风被输送到出风罩62，此时可以减小不必要的热风吹向中梁22侧带来的耗电量损耗；当风机4以第二转速运行时，进风罩61内的挡风阀片611会被吹开，进风口处于打开状态，此时有热风被输送到出风罩62，热风从下向上吹向中梁22，此时可以有效地防止在中梁22上产生凝露。
根据本发明的一些实施例，当对开门冰箱100的运行工况为高湿工况时，压缩机3停止运行后，风机4以第二转速继续运行第一预设时间t。压缩机3停止运行后，中梁22内部预埋的防露管温度开始下降，中梁22侧的温度开始下降，而冷凝器5仍有很大一部分余热，风机4以第二转速继续运行第一预定时间t时，进风罩61内的挡风阀片611被吹开，进风口处于打开状态，输风管组件可以继续向中梁22上输送热风，使得中梁22处的温度升高，并使得中梁22处的空气流通加快，从而进一步地提高了对开门冰箱100的防凝露效果。此外，还进一步地降低了压缩机仓11内和压缩机3的温度，从而进一步地减小了压缩机3下次启动时的负荷。
可选地，第一预设时间t满足：10min≤t≤50min。其具体数据可以根据对开门冰箱100的具体规格型号以及对开门冰箱100运行时的具体环境温度和环境湿度设定，本发明对此不作具体限定。
下面参照图7描述根据本发明实施例的对开门冰箱100的控制方法的一个具体实施例。
为方便描述，以某款对开门冰箱100为例，对普通工况和高湿工况的环境温度范围和环境湿度范围进行说明。
参照表1，表中“○”表示对开门冰箱100运行普通工况时的环境温度和环境湿度范围，表中“●”表示对开门冰箱100运行高湿工况时的环境温度和环境湿度范围。
表1对开门冰箱100的运行工况对应的环境温度和环境湿度
Figure PCTCN2017107388-appb-000001
例如，当环境温度T和环境湿度H满足：14℃＜T≤22℃且H＞75％RH时，对开门冰箱100运行高湿工况，当环境温度T和环境湿度H满足：14℃＜T≤22℃且H≤75％RH时，对开门冰箱100运行普通工况。
当对开门冰箱100的运行工况为高湿工况时，压缩机3停止运行后，不同环境温度和环境湿度对应的风机4继续运行第一预设时间t的取值如表2所示。
表2高湿工况下不同环境温度和环境湿度对应的第一预设时间t
Figure PCTCN2017107388-appb-000002
例如，当环境温度T和环境湿度H满足：14℃＜T≤22℃且75％RH＜H≤90％RH时，压缩机3停止工作后，风机4以第二转速继续运行10min；当14℃＜T≤22℃且H＞90％RH时，压缩机3停止工作后，风机4以第二转速继续运行20min；当22℃＜T≤28℃且H＞90％RH时，压缩机3停止工作后，风机4以第二转速继续运行30min；当T＞35℃且75％RH＜H≤90％RH时，压缩机3停止工作后，风机4以第二转速继续运行40min；当T＞35℃且H＞90％RH时，压缩机3停止工作后，风机4以第二转速继续运行50min。
例如，压缩机3启动前，当温度传感器检测到当前环境温度为25℃，湿度传感器检测到当前湿度为50％RH时，对开门冰箱100运行普通工况，风机4以第一转速运行，进风罩61内的挡风阀片611不会被吹开或者被吹开的幅度非常小，进风口处于关闭状态，此时基本没有热风能吹到出风罩62处，耗电量较低。压缩机3停止工作后，风机4停止工作。
当温度传感器检测到当前环境温度为25℃，湿度传感器检测到当前湿度为70％RH时，对开门冰箱100运行高湿工况，风机4以第二转速运行，由于风量较大，进风罩61内的挡风阀片611会被吹开，进风口处于打开状态，此时有热风被输送到出风罩62，热风从下向 上吹向中梁22。压缩机3停止工作时，风机4以第二转速继续运行10min，此时仍有热风被吹向中梁22，有效地防止了在中梁22上产生凝露且可以降低压缩机仓11内和压缩机3的温度，从而减小了压缩机3下次启动时的负荷。
根据本发明实施例的对开门冰箱100的控制方法，有效地防止了在中梁22上产生凝露，提高了对开门冰箱100的可靠性。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“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。
