图3是本发明再一实施方式中冰箱控制方法的流程示意图；
图4是本发明一实施方式中冰箱的制冷系统示意图。
具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
在本发明的实施方式中，以冰箱为例对本发明的启动控制方法做具体的阐释，但应当说明的是，在下述的实施方式中所涉及的技艺精神可以被替换地利用到其它形式的制冷设备上，示范性地，例如冷柜。
本发明在启动阶段输入直线压缩机以尽量大的功率，以快速穿过压缩机的共振带，减小噪音的产生，同时避免压缩机通电瞬间产生剧烈压降。参考图1，本发明的启动控制方法包括：
判断冰箱是否由停止状态进入启动状态；
若是，则调用启动模式，使直线压缩机以预设输入功率运行预设时间T1；预设输入功率大于与所述直线压缩机匹配的正常启动输入功率，小于等于所述直线压缩机的最大输入功率，并且，在启动模式开始时，即压缩机通电的同时，将制冷系统部分或全部阻断一较短的预设时间T2。
若冰箱启动时不是由停止状态进入，例如，暂停后启动，则进入常规控制模式。
具体地，停止状态，是指未有电流通过冰箱内电子器件时冰箱的状态。例如，冰箱初次上电前，或断电长时间后再次通电前，或在用户处第一次通电前。
可以理解的是，在所述停止状态下，冰箱冷藏间室和冷冻间室温度一致，冰箱间室的温度可以和室温相同或相近。
直线压缩机常规控制模式下，启动输入功率一般是稳定运行输入功率的8-10倍。例如直线压缩机稳定运行输入功率为10w，那么，该直线压缩机匹配的正常启动输入 功率可达到80w～100w，本实施例中的预设输入功率可大于100W，当然，也可直接设为最大输入功率，例如160w。
一般地，多数型号的直线压缩机是在上电的一分钟后进入稳定工作状态，所以本实施例中预设时间T1至少为一分钟。当然，也不排除有少数型号的直线压缩机在上电的一分钟内就可以进入稳定工作状态，此时预设时间T1也可以设置为小于一分钟。
在冰箱由停止状态进入启动状态时为直线压缩机提供超过与其匹配的正常启动输入功率，压缩机的活塞行程更快增大，壳体内压力迅速下降。为了避免压缩机压力迅速降低的过程影响部件的稳定性，在压缩机通电的同时，通过部分或全部阻断制冷系统回路使压缩机排气侧压降速率减缓，压缩机各部件在一个较缓和的过程中达到动态平衡。阻断的时间T2短于启动模式下压缩机以前述预设输入功率运行的时间T1，以在恢复制冷循环系统通畅后压缩机仍能以预设输入功率运行，快速制冷。此时，虽然压缩机维持一较高的功率，但由于压缩机内已经达到动态平衡，对部件的损伤较小。
参考图1，在本发明一实施例中，在压缩机通电的同时，关闭风机以减小制冷系统向间室输送冷量的速率，并在5秒后开启风机，恢复送风。
参考图2，在本发明又一实施例中，在压缩机通电的同时，关闭制冷剂回路中设置于毛细管上游的电磁阀以截断制冷剂通路，并在5秒后开启阀门，制冷剂恢复向蒸发器流动。
参考图3，在本发明又一实施例中，关闭风道的风门以阻止冷气向间室流通，并在5秒后开启风门，实现制冷回路的通畅。
进一步的，在调用启动模式之前，判断间室是否高于预设温度，若是，则调用启动模式，若否，则进入常规控制模式。优选的，该间室为冷冻间室。该预设温度例如为-5℃。如此，当间室与环境一致，均处于低温时，例如在高纬度地带的冬季，可以避免调动启动模式，减小压缩机的损耗且节约能源。
直线压缩机运行预设时间T1后，退出启动模式，根据冰箱间室内温度及外部环境温度控制直线压缩机运行。
参考图4，冰箱制冷系统包括依次连接形成回路的蒸发器、毛细管、电磁阀10、冷凝器20及直线压缩机30，制冷剂在其中循环。其中，蒸发器包括冷藏蒸发器41及冷冻蒸发器43，毛细管包括冷藏毛细管51及冷冻毛细管53。冷藏蒸发器41和冷藏毛细管51连接，冷冻蒸发器43和冷冻毛细管53连接，两者再相并联。电磁阀10将制冷剂分流至冷藏毛细管51和/或冷冻毛细管53，以实现冷藏/冷冻室所需冷量分配。进一步的，电磁阀 10为三通阀，可控制冷冻或冷藏系统分别或协同制冷。
冰箱至少包括冷藏室和冷冻室，二者在竖直方向上排列。冷藏蒸发器41与冷藏风道61连接，风道61通向冷藏室；冷冻蒸发器43与冷冻风道63连接，风道63通向冷冻室，使冷藏蒸发器41仅对冷藏室制冷，冷冻蒸发器43仅对冷冻室制冷。风道61、63是由数个壁围合的通道，用于将蒸发器41、43冷却的空气导入相应的间室。冷藏风道61与冷冻风道63各配备冷藏风机81、冷冻风机83以提高制冷效率。风道61、63之间可以设置风门(未图示)，风门能够受控地打开，以允许冷冻蒸发器43与冷藏蒸发器41进行空气交换。
冰箱还包括电脑板，用于判断冰箱是否由停止状态进入启动状态，以及控制直线压缩机的工作模式。
若是，则调用启动模式，控制直线压缩机在预设输入功率下运行预设时间T1。
其中，预设时间采用单片机计时。预设输入功率大于与所述直线压缩机匹配的正常启动输入功率，小于等于所述直线压缩机的最大输入功率。
电脑板还控制在启动模式开始时，制冷循环系统至少部分阻断预设时间T2。T2<T1。
具体的，电脑板在压缩机通电的同时可以控制风机81和/或83关闭5秒，然后开启。
还可以控制制冷剂回路中的电磁阀10关闭5秒，然后开启；又或者控制风门关闭5秒后开启。
进一步地，运行预设时间T1后退出启动模式，根据冰箱间室内温度及外部环境温度控制直线压缩机运行。
具体地，冰箱间室内温度可用于控制所述直线压缩机的启停。外部环境温度可分为多个连续的温度区间，对应每个温度区间设置直线压缩机的运行参数，当前冰箱间室内温度大于目标温度且与目标温度的温差大于预设温差时直线压缩机按照相应运行参数运行。
以上实施方式仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施方式对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施方式所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施方式技术方案的精神和范围。
