Description

恒温控制方法、电子设备及恒温酒柜 技术领域
本发明涉及冷藏装置技术领域，特别涉及一种恒温控制方法、电子设备及恒温酒柜。
背景技术
酒柜作为一种储存和展示酒或其他饮品的冷藏装置，广泛应用于人们的生活中，如应用在家庭、机场、酒店等场所。随着人们生活品质的提高，对酒柜的性能需求也越来越高。为了便于酒的长期储存，需要使酒柜内保持一定的温度。
目前市场上的酒柜设置为单制冷功能，对应酒柜内的多个间室配置多个蒸发器和风机，即在检测温度高于设定的上限温度时，压缩机启动制冷，而在检测温度低于设定的下限温度时，压缩机停机。这样的单制冷方式带来的问题是：对于较低的环境温度，酒柜中温度由于过低，比如低于5℃，使其并不能满足酒品储藏最低温度的要求；另一方面，单制冷的方式可能使酒品的储藏温度存在较大的波动，不利于酒品的优质储藏。
此外，现有的酒柜恒温控制方法通常包括将环温划分成几个区间，通过控制每个环温区间内的设置档位温度的压缩机的开机点温度和关机点温度不同，从而实现恒温。上述方法需要在划分的每个环温区间测试多个设置档位的温度以调整每个设置档位在每个环温区间内的压缩机的开机点温度和关机点温度；然后，对调整后的开机点温度和关机点温度进一步验证才能确认最终的开机点温度和关机点温度。因此，现有的恒温控制方法需要耗费大量的时间及实验室资源，影响产品开发进度及上 市时间。

为了使本发明的目的、技术方案及优点更加清楚明白，下面结合实施例及附图，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。
如图1所示，本发明一实施例中提供一种恒温控制方法1000，其适用于制冷设备，通过修正不同环境温度对制冷设备的压缩机的开机点温度和关机点温度的影响，消除制冷设备的间室内的实际温度随环境温度的波动，实现间室内的实际温度和设定档位温度相同。
恒温控制方法1000包括：
于基准环境温度下，获取间室的第一实际温度和基准档位温度之间的第一差值；
根据第一差值，修改制冷设备的压缩机的开机点温度和关机点温度，获得第一修正开机点温度和第一修正关机点温度；
获取实际环境温度下，基准档位温度和间室的第二实际温度之间的第二差值；
根据第二差值，修改第一修正开机点温度和第一修正关机点温 度，获得第二修正开机点温度和第二修正关机点温度；以及
控制制冷设备的压缩机根据第二修正开机点温度开机，以及，控制制冷设备的压缩机根据第二修正关机点温度停机。
在一较佳的实施方式中，获取间室的第一实际温度和基准档位温度之间的第一差值的步骤包括：
于基准环境温度下，设置间室的基准档位温度；
压缩机根据第一修正开机点温度和第一修正关机点温度进行制冷，并测量间室的第一实际温度；
计算第一实际温度和基准档位温度之间的第一差值。
本实施例中，以基准环境温度和基准档位温度为基础，确定基准环境温度对第一实际温度的影响值，即第一差值，并以第一差值对压缩机的第一开机点温度和第一关机点温度进行修正，得以消除基准环境温度对第一实际温度的影响，确保第一实际温度和基准档位温度之间能够无限接近。
其中，考虑到制冷设备例如是恒温酒柜，因此，基准环境温度例如是32℃，基准档位温度例如是12℃。
此外，依据制冷设备的种类不同，可适当的调整基准环境温度和基准档位温度。
在一较佳的实施方式中，获取实际环境温度下，基准档位温度和间室的实际温度之间的第二差值的步骤包括：
于多个不同的设定环境温度下，设置间室的基准档位温度；
压缩机根据第一修正开机点温度和第一修正关机点温度进行制 冷，分别测量间室的实际温度，分别测量多个不同的设定环境温度对应的间室的实际温度，并获得多个第三实际温度；
计算每一第三实际温度和所述基准档位温度之间的差值，获得多个第三差值；
依据多个第三差值和多个不同的设定环境温度建立线性回归方程；
根据线性回归方程获得与实际环境温度对应的第二差值。
本实施例中，在完成基准环境温度和基准档位温度下，对压缩机的第一开机点温度和第一关机点温度的参数修正后；进一步测试不同的设定环境温度和基准档位温度下，不同的设定环境温度对第三实际温度的影响值，即，第三差值，根据多个不同的设定环境温度和多个第三差值，建立线性回归方程，以获得任意实际环境温度对间室的实际温度的影响值，即，第二差值。最后，通过第二差值修正压缩机的第一修正开机点温度和第一修正关机点温度，形成第二修正开机点温度和第二修正关机点温度。
进一步，设置制冷设备的间室的设定档位温度，控制压缩机按照第二修正开机点温度和第二修正关机点温度进行制冷，此时，间室的第二实际温度和设定档位温度始终相等。
需要说明的是，设置档位温度是在基准档位温度上进行变化的温度，设置档位温度依据实际的储物需求自行设定，通常设置档位温度大于或者小于基准档位温度。
另外，通过测量不同的设定环境温度对基准档位温度对应的实际 温度的影响，并建立线性回归方程，实质上获得了不同的环境温度对间室的实际温度的影响值(第二差值)，以此为参数修正压缩机的开机点和关机点，进而使得环境温度对实际温度的影响被修正，确保了间室的实际温度和设定档位温度始终一致。
在一较佳的实施方式中，考虑到制冷设备例如是恒温酒柜，因此，多个不同的设定环境温度包括43℃、21℃和12℃。
此外，依据制冷设备的种类不同，可适当的调整基准环境温度和基准档位温度。
本发明还提供一种电子设备，包括存储器和处理器，所述存储器储存有可在所述处理器上运行的计算机程序，所述处理器执行计算机程序时实现恒温控制方法1000。
如图2至图9所示，本发明还提供一种恒温酒柜100，恒温酒柜100包括箱体、制冷单元和控制主板，箱体包括间室，间室内设置有温度传感器，温度传感器用于检测间室的实际温度；制冷单元包括压缩机，蒸发器40、风机和风道组件20；控制单元电连接压缩机和温度传感器；其中，控制主板用于执行恒温控制方法1000。

风门组件包括第一阀门31、第二阀门32以及开关33，开关33电连接第一阀门31和第二阀门32。
第二盖板22上设有第一出风口221和第二出风口222，第一阀门31设置于第一出风口221处，第二阀门32设置于第二出风口222处；其中，第一出风口连通上送风风道201，第二出风口222连通下送风风道202。
上送风风道201还连通第三盖板23顶端的开口231，开口231连通上送风单元24的第一送风口241，其中，上送风单元24和内胆10的顶部侧壁之间的空间构成上流通通道，从上送风风道201中送出的风经开口231、上流通通道以及第一送风口241传递至上间室101中。
在一较佳的实施方式中，第一送风口241设置于上送风单元24的前端，上送风单元24的前端为靠近上间室101的前侧。
下送风风道202还连通第二盖板22上第一开口223，第一开口 223和第三盖板23上的第二开口233相对应且相互贯通，其中，第二开口233连通下送风单元25的第二送风口253。
下送风单元25包括第一通道板251和第二通道板252，第一通道板251和第二通道板252卡合连接，第一通道板251和第二通道板252之间的空间构成下流通通道。从下送风风道202中送出的风经第一开口223、第二开口233、下流通通道以及第二送风口253传递至下间室102中。
其中，第二送风口253设置于第二通道板252朝向下间室102的一侧。较佳的，第二送风口253设置第二通道板252的前端，第二通道板252的前端靠近间室的前侧。
本实施例中，内胆10的间室通过隔板26被划分为上间室101和下间室102，下送风单元25例如卡合固定于隔板26朝向下间室102的一侧。即，下送风单元25位于内胆10的间室的中部，且位于下间室102的顶部，但不以此为限。
如图6至图9所示，第三盖板23上设置第一回风口232和第二回风口234，第一回风口232连通上间室101和第一回风风道203；第二回风口234连通下间室102和第二回风风道204；其中，第一回风风道203和第二回风风道204的的下端分别与蒸发器40连通。
本实施例中，第一送风口241、第二送风口253分别设置于上间室101和下间室102的顶部靠前的位置，有助于将风机30送出的风均匀的传递至整个间室中；第一回风口232和第二回风口234分别设置于上间室101和下间室102的底部靠下的位置，有助于将间室内的 空气尽快通过第一回风道203和第二回风道204传递至蒸发器40，提高温度控制效率。
需要说明的是，酒柜100中仅设置单一蒸发器40、单一风机30，藉由风门组件，将风机30送出的空气朝向上送风风道201和/或下送风风道202中分配，实现单系统酒柜的双温区的恒温控制。
如图2、图3、图5和图6所示，恒温酒柜100还包括加热单元，加热单元包括第一加热丝51，第二加热丝52以及第三加热丝53，第一加热丝51设置隔板26的底部，即，设置于上间室101的底部；第二加热丝52设内胆10的底部的外侧，即，设置于下间室102的底部；第三加热丝53设置于内胆10的后壁的远离风道组件的一侧，其中，第三加热丝53和蒸发器40相对。
本实施例中，将第三加热丝53设置成与蒸发器40相对的位置，便于后续酒柜100的恒温控制时，迅速对蒸发器40提供热量，风机30启动后，可迅速将蒸发器40处的热量循环至间室内，以实现快速升温。
另外，第一加热丝51和第二加热丝52分别设于上间室101和下间室102的底部，利用热空气上浮的原理，可实现间室内的均匀制热。
通过加热单元提供热量，满足环境温度低或者酒柜100需要在较高温度下储存酒品的情况，酒柜100维持恒温的需求。
由上述可知，酒柜100大致包括制冷单元、加热单元、温度传感器单元以及控制主板，，制冷单元包括压缩机、蒸发器40、风机30和风道组件20，利用蒸发器40制冷，并以风机向酒柜100的箱体内 的间室中输送经蒸发器40热交换形成的冷风实现制冷；利用加热单元向所述间室内传递由加热装置产生的热量实现制热；温度传感器单元用于分别检测所述间室内的实际温度和所述恒温酒柜外部的实际环境温度；控制主板根据所述间室内的实际温度选择所述制冷单元制冷和/或选择所述加热单元制热。
而，酒柜100的恒温控制模式大致包括，1)上间室101和下间室102都需要制冷；2)上间室101和下间室102其中之一需要制冷，其中之另一需要制热；3)上间室101和下间室102都需要制热。
当上间室101和下间室102都需要制冷，恒温控制过程包括，单一的制冷过程。
制冷过程包括：
首先，控制主板分别获取上间室101的实际温度和下间室102的实际温度，若判断上间室101的实际温度高于第一设定档位温度，且下间室102的实际温度高于第二设定档位温度；
其次，控制主板获取实际环境温度，利用实际环境温度代入线性回归方程获得与实际环境温度相对应的修正温度差值(即，恒温控制方法1000中的第二差值)，根据此修正温度差值修正压缩机的开机点温度和关机点温度；
接着，压缩机根据修正后的开机点温度和关机点温度启停，进行制冷；
然后，控制主控控制风门组件中的开关33控制第一阀门31和第二阀门32分别打开，风机30启动，将蒸发器40提供的冷量通过第 一风门221、上送风风道201以及上送风单元24内的上流通通道和第一送风口241传递至上间室101内，且使得上间室101的实际温度和第一设定档位温度相同；以及，风机30启动，将蒸发器40提供的冷量通过第二风门222、下送风风道202以及下送风单元25内的下流通通道和第二送风口253传递至下间室102内，且使得下间室102的实际温度和第二设定档位温度相同。
需要说明的是，在根据实际环境温度代入线性回归方程获得对应的修正温度差值对压缩机的开机点温度和关机点温度修正之前，压缩机的开机点温度和关机点温度已经经过基准修正过程，其中，基准修正过程包括：获取基准环境温度下，基准档位温度和间室的实际温度之间的基准温度差值(即，恒温控制方法1000中的第一差值)，并以基准档位温度和间室的实际温度之间的基准温度差值对压缩机的初始开机点温度和初始关机点温度进行基准修正，获得第一修正开机点温度和第一修正关机点温度。
因此，根据修正温度差值修正第一修正开机点温度和第一修正关机点温度，获得第二修正开机点温度和第二修正关机点温度，压缩机按照第二修正开机点温度和第二修正关机点温度运行。
换言之，经过基准修正之后，压缩机的第一修正开机点温度和第一修正关机点温度再经过二次修正，二次修正的修正温度差值通过线性回归方程获取，主要用于消除实际环境温度对间室的实际温度的影响，确保间室的实际温度和设定档位温度相一致。
另外，当判断第一设定档位温度和第二设定档位温度之间的温差 大于预设值时，控制主板识别第一设定档位温度和第二设定档位温度中温度较低的一个，并控制风门组件中的开关打开与设定档位温度较低的一个间室对应的阀门，即，优先对设定档位温度较低的一个间室进行制冷。其中，优先对设定档位温度较低的一个间室进行制冷，有助于使得两个间室尽快到达各自对应的设定档位温度。
进一步，当判断第一设定档位温度和第二设定档位温度之间的温差小于预设值时，控制主板控制风门组件中的开关同时将连通上间室的第一出风口处的第一阀门和连通下间室的第二出风口处的第二阀门一并打开，同时向上间室和下间室提供冷量，同样也有助于使得两个间室尽快到达各自对应的设定档位温度。
当上间室101和下间室102的其中之一需要制冷，其中之另一需要制热时，酒柜100的恒温控制过程具体包括：制冷过程和制热过程。
制冷过程和上述上间室101和下间室102都需要制冷的控制过程相似，即，对进行过基准修正的压缩机的开机点温度和关机点温度根据实际环境温度对应的温度差值进行二次修正，压缩机按照二次修正的开机点温度和关机点温度运行。打开风机30，开关33控制第一阀门31和第二阀门32的其中之一打开，冷空气通过上送风风道201、上送风单元24和第一送风口241进入上间室101中，使得上间室101的第一设定档位温度和实际温度相同；或者，冷空气通过下送风风道202、下送风单元25和第二送风口253进入下间室102中，使得下间室102的第二设定档位温度和实际温度相同。
制热过程包括：
于压缩机和蒸发器40制冷过程中，控制上间室101的底部的第一加热丝51和下间室102的底部的第二加热丝52的其中之一启动，朝向对应的上间室101供热或者朝向对应的下间室102供热。
开关33控制第一阀门31和第二阀门32都处于关闭状态。
控制与蒸发器40对应的第三加热丝53启动，第三加热丝53朝向蒸发器40提供热量，至蒸发器40的实际温度上升至预设温度时，开关33控制第一阀门31和第二阀门32的其中之另一打开，风机30启动，热空气经上送风风道201、上送风单元24和第一送风口241进入上间室101中，使得上间室101的第一设定档位温度和实际温度相同；或者，热空气通过下送风风道202、下送风单元25和第二送风口253进入下间室102中，使得下间室102的第二设定档位温度和实际温度相同。
本实施例中，通过布置与蒸发器40对应的第三加热丝53，以使对蒸发器40制冷后，再将热空气传递到需要制热的间室内，实现待制热的间室内的实际温度尽快与设定温度相同，提高了恒温控制的制热控制的效率。
另外，第三加热丝53的加热速率可大于第一加热丝51、第二加热丝52的加热速率。
当上间室101和下间室102都需要制热，恒温控制过程包括，单一的制热过程。
制热过程包括：
控制第一加热丝51、第二加热丝52以及第三加热丝53同时启动；
开关33控制第一阀门31和第二阀门32分别打开；
风机30启动，热空气经上送风风道201、上送风单元24和第一送风口241进入上间室101中，使得上间室101的第一设定档位温度和实际温度相同；以及，热空气通过下送风风道202、下送风单元25和第二送风口253进入下间室102中，使得下间室102的第二设定档位温度和实际温度相同。
上述第一阀门31和第二阀门32同时打开的前提条件为，第一设定档位温度和第二设定档位温度相近。
另外，当判断第一设定档位温度和第二设定档位温度之间的温差大于预设值时，控制主板识别第一设定档位温度和第二设定档位温度中温度较高的一个，并控制风门组件中的开关打开与设定档位温度较高的一个间室对应的阀门，即，优先对设定档位温度较高的一个间室进行制热。其中，优先对设定档位温度较高的一个间室进行制热，有助于使得两个间室尽快到达各自对应的设定档位温度。
综上，本发明提供一种恒温控制方法、电子设备及恒温酒柜，恒温控制方法包括在基准环境温度和间室的基准档位温度下，对压缩机的开机点温度和关机点温度进行基准修正，在此基础上，在多个设定环境温度和间室的基准档位温度下，获得不同环境温度对间室的设定档位温度影响的温度差值，根据此温度差值，修正实际环境温度下，压缩机的开机点温度和关机点温度，进而确保设定档位温度和间室的实际温度始终维持一致。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施 本发明的范例。此外，上面所描述的本发明不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。必需指出的是，本发明还可有其他多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
