具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
在相关技术中，冷冻肉类等物品想要食用需要额外花时间解冻，浪费用户时间和精力。并且，有些情况下需要加热或者维持较高的温度，例如：水果坚果烘干、热菜保温、暖酒、暖奶、烘干抹布、手袋预热等。
针对相关技术中，解冻过程需要额外消耗的情况，本申请实施例提供了一种加热系统，能够利用制冷设备上制冷系统的热量对物体进行加热，起到了节能减排的作用，有效的提高了资源的利用率。
本方案针对以上问题，提供一种具备加热并保温功能的冰箱系统，可以解决以上问题，提供用户的使用体验。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的加热方法进行详细地说明。
如图1所示，本申请实施例提供的一种加热系统，该系统包括：控制单元，以及与所述制冷设备的第一通路并联的第二通路。
其中，所述第一通路为所述制冷设备的冷凝器与压缩机之间的通路；所述第二通路上设置有换热器；所述换热器设置于加热室内；所述第一通路上设置有第一电动阀；所述第二通路上的所述换热器的两侧分别设置有第二电动阀和第三电动阀。
所述控制单元，用于在所述加热室内的内部温度小于或者等于设定温度的情况下，根据所述内部温度与所述冷凝器的盘管温度的差值，调整所述第一电动阀，所述第二电动阀以及所述第三电动阀，以提升所述内部温度。
示例性地，上述制冷设备可以为柜机空调室内机，也可以为冰柜、冰柜等具有制冷功能的设备。将本申请实施例提供的制冷系统应用到制冷设备上，可以使得制冷设备具有制热功能，且不需要额外的能源消耗。
示例性地，如图2所示，为相关技术中制冷设备上的制冷系统，其工作原理为：压缩机将常温气态制冷剂压缩为高温气态制冷剂，高温气态制冷剂经冷凝器(冷凝器)散热后，变为常温液态制冷剂。常温液态制冷剂经过节流单元节流降压后，输送到冷冻室蒸发器和冷藏室蒸发器中，吸收热量后气化为常温气态制冷剂，并再次输送到压缩机中循环使用。
基于上述内容，本申请实施例想到可以利用冷凝器散发的热量对食物进行加热。因此，在如图2所示的制冷系统的基础上，本申请实施例对其进行了改进，得到如图1所示的加热系统。该加热系统将包含有加热室的第二通路并联接入制冷系统的冷凝器与压缩机之间的第一通路，使得在需要进行加热的情况下，高温气态制冷剂能够先进入加热室进行散热，再流进冷凝器中。
示例性地，为了能够实现上述功能，可以在第一通路上设置第一电动阀，该第一电动阀在关闭时能够使得高温气态制冷剂能够通过第二通路进入冷凝器中。同时，为了保证第一通路和第二通路在同一时间只有一个处于开启状态，还需要在第二通路上设置电动阀。
示例性地，为了避免在第一通路处于开启状态的情况下，高温气态制冷剂进入加热室的换热器内，在加热室的换热器与压缩机之间的第二通路 上还需要设置第二电动阀。当第一电动阀开启时，关闭第二电动阀，使得高温气态制冷剂通过第一通路进入冷凝器中。
示例性地，为了避免在第一通路处于开启状态的情况下，高温气态制冷剂进入加热室的换热器内，还需要在加热室的换热器与冷凝器之间的第二通路上还需要设置第三电动阀。当第一电动阀开启时，关闭第三电动阀，使得高温气态制冷剂通过第一通路进入冷凝器中。
示例性地，上述控制单元可以为制冷设备上用于控制制冷系统的控制单元，也可以为单独控制加热系统的控制单元。
示例性地，如图3所示，为本申请实施例提供的加热室结构示意图，包括：换热器，温度旋钮等。用户可以通过温度旋钮设置加热室内的加热温度，换热器用于在使用高温气态制冷剂进行加热时将高温其气态制冷剂的热量散发到加热室内。
可选地，基于上述原理，在用户开启加热模式、且加热室内的温度小于或者等于用户设定的温度的情况下，本申请实施例提供的加热系统，可以参照以下加热逻辑对加热室进行加热。
示例性地，在所述加热室内的内部温度小于或者等于设定温度的情况下，所述控制单元，具体用于在所述内部温度小于或者等于所述盘管温度的情况下，控制所述第二电动阀和所述第三电动阀开启，并控制所述第一电动阀关闭。
示例性地，所述控制单元，具体用于在所述内部温度大于所述盘管温度的情况下，控制所述第一电动阀开启，所述第二电动阀以及所述第三电动阀关闭，并控制所述加热装置通电，通过所述加热装置提升所述内部温度。
可以理解的是，在进行加热之前，需要判断具体地加热方式，当加热室内的内部温度小于或者等于冷凝器的盘管温度时，可以使用制冷剂的热量进行加热；当加热室内的内部温度小于冷凝器的盘管温度时，可以使用加热装置进行辅助加热。在使用加热装置进行辅助加热之前，需要将上述第一电动阀、第二电动阀以及电三电动阀进行复位。
举例说明，基于图3，如图4所示，用户通过温度旋钮调整设定温度，并打开即热功能后，加热系统启动加热模式。此时，需要判断加热室内温 度T1(即上述内部温度)是否小于设定温度T2；当T1<T2时，还需要判断加热室温度T1是否小于冷凝器温度T3，若T1≤T3，则打开如图1所示的电动阀2和电动阀3，并关闭电动阀1，此时，使用高温气态制冷剂对加热室进行加热。若T1＞T3，则需要控制电加热丝(即上述加热装置)通电，通过电加热丝对加热室内加热，直至加热室内温度达到设定温度。
示例性地，所述控制单元，具体用于在所述内部温度等于所述设定温度的情况下，控制所述第二电动阀和所述第三电动阀关闭，并控制所述第一电动阀开启。
举例说明，如图4所示，当加热室温度等于设定温度后，加热系统关闭加热模式，并控制电动阀复位。即控制上述电动阀1开启，并关闭上述电动阀2和电动阀3。
在一种可能的实现方式中，为了避免加热室内温度过高，还可以为加热室设置空气管，以使得加热室外的空气与加热室内的空气进行热交换，降低加热室内的温度。
示例性地，所述加热室还设置有空气管；所述空气管上设置有第四电动阀；所述空气管用于加热室内外的空气流动；所述控制单元，还用于在所述内部温度大于所述设定温度的情况下，控制所述第四电动阀开启，以降低所述加热室内的内部温度。
举例说明，如图3所示，该加热室还设置有室外空气管(即上述空气管)，同时，该室外空气管上还设置有电动阀4，用于控制该室外空气管的开启和关闭。该加热室还设置有紫外灯和紫外灯开关，用于加热室内物品的杀菌。
示例性地，如图4所示，当加热室内温度T1大于设定温度T2时，需要打开电动阀4(即上述第四电动阀)，向加热室内导入空气，平衡加热室内温度。并在加热室内温度T1等于设定温度T2的情况下，关闭电动阀4。
本申请实施例提供的加热系统，在加热室内的内部温度小于或者等于设定温度的情况下，能够利用制冷设备的冷凝器的余温对加热室进行加热，使得制冷设备不仅有制冷功能，还能够具有制热功能，满足不同用户的需求。
