本发明涉及家电技术领域，特别是涉及一种冰箱的散热控制方法与冰箱。
背景技术
随着社会日益发展和人们生活水平不断提高，人们的生活节奏也越来越快，因而越来越愿意买很多食物放置在冰箱中，冰箱已经成为了人们日常生活中不可缺少的家用电器之一。
由于一体化装修普及度程度提高，人们对冰箱的要求标准也逐步提升，不仅是外观颜值高、性能优越，还要求其能够符合家庭装修需求。嵌入式冰箱不仅具备一般冰箱的功能，还能够与橱柜的风格融为一体。把冰箱嵌入橱柜在形式上将厨房形成了一个整体，比较美观。
目前的嵌入式冰箱一般在后背设置有冷凝器，在橱柜的底部和顶部设置有出风口，通过自然对流形成通风散热循环系统。但是这种形式的嵌入式冰箱对橱柜或者四周墙壁的预留距离有较大要求，往往需要预留15㎝至30㎝。预留空间过大会影响整体美观程度，若预留空间不足，又会影响冰箱散热，进而严重影响冰箱的正常使用寿命，此外，还会对周围的橱柜或墙壁造成损坏。

进一步地，本发明的冰箱的散热控制方法与冰箱，根据运行信号确定压缩机停机时，控制第一冷却风机停机。在根据运行信号确定压缩机停机的步骤之后还包括：控制第二冷却风机继续开启预设时长之后停机。其中，预设时长为2分钟至5分钟。在压缩机停止工作之后，首先使第一冷却风机停机，避免冷风继续进入压缩机仓；保持第二冷却风机继续运行预设时长后停机，可以避免压缩机仓和出风风道中热气残留，影响冰箱的散热效果。第二预设时长设置为2分钟至5分钟，使得第一冷却风机和第二冷却风机的开、关机时间点更加合理，有效增强冰箱的整体散热效果，可以有效减少冰箱与周围橱柜或墙壁之间需要预留的散热距离，从而提升冰箱与周围空间的整体美观度，此外，可以实现自由嵌入橱柜或墙壁间隙，不必预先对橱柜或墙壁进行改造，使得橱柜必须设置有橱柜进风口和橱柜出风口。
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。

具体实施方式
图1是现有技术中冰箱300的结构示意图，该冰箱300为嵌入式冰箱，设置于橱柜200中。如图1所示，目前的嵌入式冰箱一般在后背设置有冷凝器303，在橱柜200的底部设置有橱柜进风口307，在顶部设置有橱柜出风口306，通过自然对流形成通风散热循环系统。具体地，按照图1中的箭头所示方向，风由冰箱300外部通过橱柜进风口307进入，再经由压缩机仓301的压缩机仓进风口304进入压缩机仓301，对压缩机302进行冷却后，经由压缩机仓出风口305流出压缩机仓301，之后沿着冰箱300与的背部与橱柜200形成的间隙向上流动，并在此过程中对冷凝器303进行冷却，最后从橱柜出风口306流出。这种自然对流形成的通风散热循环系统对嵌入式冰箱与橱柜200或者四周墙壁的预留距离有较大要求，往往需要预留15㎝至30㎝。预留空间过大会影响整体美观程度，若预留空间不足，又会影响冰箱散热，进而严重影响冰箱的正常使用寿命，此外，还会对周围的橱柜200或墙壁造成损坏。
本发明首先提供了一种冰箱100，可以可以防止从压缩机仓12排出的热风直接吹向冰箱100周围的橱柜200或墙壁，避免长时间的热风环境损坏橱柜200或墙壁。此外，可以防止进入压缩机仓12的冷风被直接排出，使得冷风能够被充分利用，有效降低压缩机仓12的温度，散热控制方法更加合理，加强冰箱100的散热效果。图2是根据本发明一个实施例的冰箱100的侧视图，图3是根据本发明一个实施例的冰箱100的后视图，图4是根据本发明一个实施例的冰箱100的俯视图，图5是根据本发明一个实施例的冰箱的散热控制装置50的结构框图。如图2至图5所示，本实施例的冰箱100一般性地可以包括：箱体10、出风风道30、制冷系统以及散热控制装置50。
其中，箱体10，其内部限定有储物空间11和压缩机仓12，且压缩机仓12位于箱体10底部，压缩机仓12处可以设置有第一进风口121和第一出风口122。在其他一些实施例中，压缩机仓12处还可以设置有第二进风口123， 增加压缩机仓12进风口的数量，可以使更多的外界冷风进入压缩机仓12，加强对压缩机仓12的散热效果。如图2所示，第一进风口121可以设置于压缩机仓12的底部前端，第二进风口123可以设置于压缩机仓12的背部下端。需要说明的是，由于箱体10的底部一般设置有垫脚，因而箱体10与水平地面或橱柜200底面之间可以形成有间隙，冰箱100外部的冷风即通过该间隙由第一进风口121和/或第二进风口123进入压缩机仓12。
储物空间11的数量以及结构可以根据需求进行配置。储物空间11按照用途不同可以配置为冷藏空间、冷冻空间、变温空间或者保鲜空间。各个储物空间11可以由分隔板分割为多个储物区域，利用搁物架或者抽屉储存物品。
本实施例的冰箱100还可以包括：门体20，可枢转地设置于箱体10的前表面，以供用户开闭储物空间11。门体20可以与储物空间11对应设置，即每一个储物空间11都对应有一个或多个门体。图2示出的本实施例的冰箱100由上至下设置有两个储物空间，且该两个储物空间可以分别设置为冷藏空间和冷冻空间，且冷冻空间可以设置于冷藏空间的下方，压缩机仓12设置于冷冻空间的下方。
出风风道30，设置于箱体10背部且竖直向上延伸，并通过第一出风口122与压缩机仓12连通，出风风道30的第二出风口31处设置有第二冷却风机32。也就是说，冰箱100外部的冷风通过第一进风口121和/或第二进风口123进入压缩机仓12，对压缩机仓12进行充分冷却，热交换后的热风通过第一出风口122经过出风风道30排出。需要说明的是，出风风道30的第二出风口31可以设置于箱体10的顶部，出风风道30排出的热风可以继续通过箱体10顶部与天花板或橱柜200顶面形成的间隙排出。第二冷却风机32的出风方向与冰箱100所在的水平地面的夹角大于等于预设角度。在一种具体的实施例中，该预设角度可以为30°。第二冷却风机32的出风方向与冰箱100所在的水平地面的夹角大于等于预设角度，可以加速出风风道30中的热风排出，此外，第二冷却风机32还可以对出风风道30中的热风具有一定冷却效果，避免排出的热风损坏橱柜200或墙壁。
如图2至图4中的箭头所示，本实施例的冰箱100外部的风沿着箱体10底部与水平地面或橱柜200底面形成的间隙，由第一进风口121和/或第二进风口123进入压缩机仓12。进入压缩机仓12的冷风对压缩机仓12内部的压 缩机42和冷凝器41充分冷却，换热后的热风通过第一出风口122进入出风风道30，通过第二冷却风机32由第二出风口31排出，最后沿着箱体10顶部与橱柜200顶面或墙壁形成间隙排出，实现对冰箱100的充分散热。
制冷系统，配置成向储物空间11提供冷量，其中制冷系统包括设置于压缩机仓12的冷凝器41、第一冷却风机43和压缩机42。具体地，冷凝器41设置于压缩机仓12内远离第一出风口122的一侧；压缩机42设置于压缩机仓12内靠近第一出风口122的一侧；且第一冷却风机43设置于冷凝器41和压缩机42之间。第一进风口121设置于压缩机仓12靠近冷凝器41的一侧，以使进入压缩机仓12的冷风依次经过冷凝器41、第一冷却风机43、压缩机42，实现对压缩机仓12充分冷却。在一种优选的实施例中，冷凝器41可以为盘管式冷凝器，且冷凝器41上缠绕有丝管或翅片，以增大换热面积。第一冷却风机43和第二冷却风机32均可以为轴流风机。
具体地，制冷系统可以为由压缩机42、冷凝器41、节流装置和蒸发器等构成的制冷循环系统。箱体10内部还可以限定有蒸发器室，且与储物空间11连通，制冷系统还包括：蒸发器，设置于蒸发器室内，以向储物空间11循环制冷。制冷系统向各种类型的储物空间提供的冷量不同，使得各种类型的储物空间内的温度也不相同。其中冷藏空间内的温度一般处于2℃至10℃之间，优先为3℃至8℃。冷冻空间内的温度范围一般处于-22℃至-14℃。不同种类的物品的最佳存储温度并不相同，进而适宜存放的储物空间也并不相同。例如果蔬类食物适宜存放于冷藏空间或者保鲜空间，而肉类食物适宜存放于冷冻空间。
如图5所示，散热控制装置50一般性地可以包括：获取模块51、判断模块52以及风机开启模块53。在以上模块中，获取模块51可以配置成获取压缩机42的运行信号。判断模块52可以配置成根据运行信号判断压缩机42是否开启。风机开启模块53可以配置成在压缩机42开启时，控制第一冷却风机43和第二冷却风机32开启，以对压缩机仓12进行散热，其中第一冷却风机43的转速大于第二冷却风机32的转速。
本实施例的冰箱100，在箱体10背部设置有出风风道30，可以防止从压缩机仓12排出的热风直接吹向冰箱100周围的橱柜200或墙壁，避免长时间的热风环境损坏橱柜200或墙壁。在压缩机42开启工作时，控制第一冷却风机43和第二冷却风机32开启，并使第二冷却风机32的转速小于第 一冷却风机43的转速，可以防止进入压缩机仓12的冷风被直接排出，使得冷风能够被充分利用，有效降低压缩机仓12的温度，散热控制方法更加合理，加强冰箱100的散热效果。
图6是根据本发明另一个实施例的冰箱的散热控制装置50的结构框图。在上一实施例的基础上，散热控制装置50还可以包括：风机停机模块54。
其中，风机停机模块54可以配置成根据运行信号确定压缩机42停机时，控制第一冷却风机43停机。此外，风机停机模块54还可以配置成：控制第二冷却风机32继续开启预设时长之后停机。在一种具体的实施例中，预设时长可以为2分钟至5分钟。即预设时长可以设置为2分钟至5分钟之间的任意时长，具体地，可以根据实际情况进行设置。例如，若预设时长为3分钟，则在确定压缩机42停机时，立即控制第一冷却风机43停机；并使第二冷却风机32继续开启3分钟后停机。需要说明的是，上述第二预设时长为3分钟的具体数值仅为例举，而并非对本发明的限定，第二预设时长可以设置为2分钟至5分钟之间的任意时长，具体地，可以根据实际情况进行设置。
本实施例的冰箱100，根据运行信号确定压缩机42停机时，控制第一冷却风机43停机。在根据运行信号确定压缩机42停机的步骤之后还包括：控制第二冷却风机32继续开启预设时长之后停机。其中，预设时长为2分钟至5分钟。在压缩机42停止工作之后，首先使第一冷却风机43停机，避免冷风继续进入压缩机仓12；保持第二冷却风机32继续运行预设时长后停机，可以避免压缩机仓12和出风风道30中热气残留，影响冰箱100的散热效果。第二预设时长设置为2分钟至5分钟，使得第一冷却风机43和第二冷却风机32的开、关机时间点更加合理，有效增强冰箱100的整体散热效果，可以有效减少冰箱100与周围橱柜或墙壁之间需要预留的散热距离，从而提升冰箱100与周围空间的整体美观度，此外，可以实现自由嵌入橱柜或墙壁间隙，不必预先对橱柜或墙壁进行改造，使得橱柜必须设置有橱柜进风口和橱柜出风口。
图7是根据本发明一个实施例的冰箱的散热控制方法的示意图。该冰箱的散热控制方法可以由上述任一实施例的散热控制装置50执行。如图7所示，该冰箱的散热控制方法可以执行以下步骤：
步骤S702，获取压缩机42的运行信号；
步骤S704，根据运行信号判断压缩机42是否开启，若是，执行步骤S706， 若否，返回执行步骤S702；
步骤S706，控制第一冷却风机43和第二冷却风机32开启，以对压缩机仓12进行散热。
在以上步骤中，步骤S706中第一冷却风机43和第二冷却风机32的转速不同，具体地，第一冷却风机43的转速大于第二冷却风机32的转速。可以防止进入压缩机仓12的冷风被直接排出，使得冷风能够被充分利用，有效降低压缩机仓12的温度，散热控制方法更加合理，加强冰箱100的散热效果。
根据步骤S702中压缩机42的运行信号可以确定压缩机42是开启还是停机。在根据运行信号确定压缩机42停机时，可以控制第一冷却风机43停机。此外，在其他一些实施例中，在根据运行信号确定压缩机42停机的步骤之后还可以包括：控制第二冷却风机32继续开启预设时长之后停机。具体地，预设时长可以为2分钟至5分钟范围内的任意时长，可以根据实际情况进行设置。在压缩机42停止工作之后，首先使第一冷却风机43停机，避免冷风继续进入压缩机仓12；保持第二冷却风机32继续运行预设时长后再停机，可以避免压缩机仓12和出风风道30中热气残留，影响冰箱100的散热效果。
在一些可选实施例中，可以通过对上述步骤的进一步优化和配置使得冰箱100实现更高的技术效果，以下结合对本实施例的一个可选执行流程的介绍对本实施例的冰箱的散热控制方法进行详细说明，该实施例仅为对执行流程的举例说明，在具体实施时，可以根据具体实施需求，对部分步骤的执行顺序、运行条件进行修改。图8是根据本发明一个实施例的冰箱的散热控制方法的详细流程图，该冰箱的散热控制方法包括以下步骤：
步骤S802，获取压缩机42的运行信号；
步骤S804，根据运行信号判断压缩机42是否开启，若是，执行步骤S806，若否，返回执行步骤S802；
步骤S806，控制第一冷却风机43和第二冷却风机32开启，以对压缩机仓12进行散热；
步骤S808，根据运行信号判断压缩机42是否停机，若是，执行步骤S810，若否，返回执行步骤S806；
步骤S810，控制第一冷却风机43停机，控制第二冷却风机32继续开 启预设时长之后停机。
在以上步骤中，步骤S806中第一冷却风机43和第二冷却风机32的转速不同，具体地，第一冷却风机43的转速大于第二冷却风机32的转速。可以防止进入压缩机仓12的冷风被直接排出，使得冷风能够被充分利用，有效降低压缩机仓12的温度，散热控制方法更加合理，加强冰箱100的散热效果。
根据步骤S802中压缩机42的运行信号可以确定压缩机42是开启还是停机。在根据运行信号确定压缩机42停机时，可以控制第一冷却风机43停机，控制第二冷却风机32继续开启预设时长之后停机。具体地，步骤S810中的预设时长可以为2分钟至5分钟范围内的任意时长，可以根据实际情况进行设置。在压缩机42停止工作之后，首先使第一冷却风机43停机，避免冷风继续进入压缩机仓12；保持第二冷却风机32继续运行预设时长后再停机，可以避免压缩机仓12和出风风道30中热气残留，影响冰箱100的散热效果。
需要说明的是，步骤S810中在确定压缩机42停机时控制第一冷却风机43停机，控制第二冷却风机32继续开启预设时长后停机，前提都是之前压缩机42处于运行状态，第一冷却风机43和第二冷却风机32也均处于工作状态。在此前提之下，压缩机42停机之后，才可以控制原本是工作状态的第一冷却风机43和第二冷却风机32停机。
本实施例的冰箱的散热控制方法，在箱体10背部设置有出风风道30，可以防止从压缩机仓12排出的热风直接吹向冰箱100周围的橱柜或墙壁，避免长时间的热风环境损坏橱柜或墙壁。第二冷却风机32的转速小于第一冷却风机43的转速，可以防止进入压缩机仓12的冷风被直接排出，使得冷风能够被充分利用，有效降低压缩机仓12的温度，散热控制方法更加合理，加强冰箱100的散热效果。
进一步地，本实施例的冰箱的散热控制方法，根据运行信号确定压缩机42停机时，控制第一冷却风机43停机。在根据运行信号确定压缩机42停机的步骤之后还包括：控制第二冷却风机32继续开启预设时长之后停机。其中，预设时长为2分钟至5分钟。在压缩机42停止工作之后，首先使第一冷却风机43停机，避免冷风继续进入压缩机仓12；保持第二冷却风机32继续运行预设时长后停机，可以避免压缩机仓12和出风风道30中热气残留， 影响冰箱100的散热效果。第二预设时长设置为2分钟至5分钟，使得第一冷却风机43和第二冷却风机32的开、关机时间点更加合理，有效增强冰箱100的整体散热效果，可以有效减少冰箱100与周围橱柜或墙壁之间需要预留的散热距离，从而提升冰箱100与周围空间的整体美观度，此外，可以实现自由嵌入橱柜或墙壁间隙，不必预先对橱柜或墙壁进行改造，使得橱柜必须设置有橱柜进风口和橱柜出风口。
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。
