Description

风冷式制冷设备 技术领域
本发明属于冷藏、冷冻技术领域，具体提供了一种风冷式制冷设备。
背景技术
风冷式制冷设备是一种用于冷藏、冷冻被储藏物(包括食材、药品、酒水、生物试剂、菌落、化学试剂等)的设备。
理论研究发现磁场对冷冻过程中冰晶的形成有较大的影响，能够降低食材的结冰温度。为此，有些风冷式制冷设备也配置了磁场发生装置，用于给被储藏物(尤其是高端食材)提供磁场，以实现被储藏物低温保鲜的目的。
但是，磁场发生装置增加了风冷式制冷设备的能耗，致使现有的风冷式制冷设备有待进一步优化。
发明内容
本发明的一个目的是，提供一种磁场发生装置能耗较低的风冷式制冷设备。
为实现上述目的，本发明提供了一种风冷式制冷设备，包括设备本体、依附于所述设备本体的风冷系统和相对于所述设备本体可抽拉的抽屉，所述抽屉能够接收所述风冷系统提供的冷风，以冷却所述抽屉内的被储藏物；所述风冷式制冷设备还包括磁场产生装置和检测装置，所述磁场产生装置通电时产生作用于所述抽屉内被储藏物的磁场，所述检测装置用于检测所述抽屉是否被抽出；所述磁场产生装置和所述检测装置配置成，在所述检测装置检测到所述抽屉被抽出时，所述磁场产生装置断电。
可选地，所述风冷系统包括风门，所述风门配置成，在所述磁场产生装置处于断电状态下时关闭，禁止所述风冷系统为所述抽屉提供冷风；在所述磁场产生装置处于通电状态下时能够打开，以使所述风冷系统为所述抽屉提供冷风。
可选地，所述风门还配置成，在所述检测装置检测到所述抽屉恢复到初始位置，并且在所述磁场产生装置通电时打开，以使所述风冷系统为所述抽屉提供冷风。
可选地，所述风冷式制冷设备还包括用于检测所述抽屉内温度的温度传 感器，所述风门还配置成，在所述磁场产生装置处于通电的状态下，如果所述温度传感器检测到所述抽屉内的温度处于预设高温区间，打开；如果所述温度传感器检测到所述抽屉内的温度处于预设低温区间，关闭。
可选地，所述检测装置包括磁体和磁场感应器，所述磁体和所述磁场感应器中的一个设置在所述抽屉上，所述磁体和所述磁场感应器中的另一个设置在所述设备本体上。
可选地，所述磁场感应器是霍尔开关或干簧管。
可选地，所述检测装置包括微动开关，所述微动开关设置在所述设备本体或所述抽屉上。
可选地，所述磁场产生装置包括设置在所述抽屉相对两侧的第一电磁线圈和第二电磁线圈。
可选地，所述磁场产生装置还包括与所述第一电磁线圈相对应的第一导磁构件和与所述第二电磁线圈相对应的第二导磁构件；并且/或者，
所述风冷式制冷设备还包括用于放置所述第一电磁线圈的第一容纳腔和用于放置所述第二电磁线圈的第二容纳腔，所述第一容纳腔和所述第二容纳腔分别与所述抽屉连通，以使所述风冷系统提供的冷风经由所述第一容纳腔和所述第二容纳腔进入所述抽屉。
可选地，所述磁场产生装置还配置成，在所述抽屉内的温度降低到了预设温度以下时再通电。
基于前文的描述，本领域技术人员能够理解的是，在本发明前述的技术方案中，通过使磁场产生装置在检测装置检测到抽屉被抽出时断电，避免了磁场产生装置在抽屉被抽出时做无用功，使得磁场产生装置通电过程中产生的磁场都能够作用到抽屉内的被储藏物上。因此，本发明的风冷式制冷设备通过提升磁场的利用率，降低了能耗。
进一步，通过使磁场产生装置在抽屉内的温度降低到了预设温度以下时再通电，使得被储藏物只在温度较低(尤其是临近结冰温度)时才被磁场产生装置产生的磁场作用，防止被储藏物结冰。因此，本发明使风冷式制冷设备进一步提升了磁场的利用率，进一步降低了能耗。
再进一步，通过设置用于称重抽屉的称重传感器或用于识别抽屉内是否存在被储藏物的图像识别单元，来判断抽屉内是否存放有被储藏物，并使磁场产生装置仅在抽屉内存放有被储藏物时再通电，避免了磁场产生装置在抽 屉内没有被储藏物时通电浪费电能。

如图1和图2所示，在本发明的一些实施例中，风冷式制冷设备包括设备本体10、抽屉20、风冷系统30、磁场产生装置40和温度传感器60。其中，抽屉20以可抽拉的方式安装到设备本体10上，抽屉20用于存放被储藏物(包括食材、药品、酒水、生物试剂、菌落、化学试剂等)。风冷系统30依附于设备本体10，并能够向抽屉20提供冷风，以冷却抽屉20内的被储藏物。磁场产生装置40用于产生磁场，并且该磁场作用于抽屉20内的被储藏物。温度传感器60以直接或间接的方式检测抽屉20内空气的温度。
如图1所示，设备本体10包括抽屉容器11，抽屉20以可抽拉的方式安装到抽屉容器11上。其中，抽屉容器11可以是为抽屉20单独配置的构件，也可以是风冷式制冷设备的冷藏室内胆、冷冻室内胆或变温室内胆。
如图2所示，抽屉容器11上设置有冷风进口111和冷风出口112。抽屉容器11通过该冷风进口111接收风冷系统30提供的冷风，从而使冷风冷却抽屉20内的被储藏物。抽屉容器11内的空气通过冷风出口112排出抽屉容器11。
如图2所示，在本发明的一些实施例中，风冷系统30包括冷冻室31、送风风道32、回风风道33、蒸发器34、风机35和风门36。其中，冷冻室31通过送风风道32和回风风道33分别与抽屉容器11连通到一起，具体地，冷冻室31通过送风风道32与冷风进口111连通，冷冻室31通过回风风道33与冷风出口112连通。蒸发器34设置在冷冻室31内，用于冷却冷冻室 31内的空气。风机35设置在冷冻室31或送风风道32或回风风道33内，用于驱动冷冻室31内的空气流动，并因此形成流向抽屉容器11的冷风。风门36设置在送风风道32内，优选地，风门36设置在送风风道32内靠近冷风进口111的位置处。风门36打开时，送风风道32内的冷风能够流向抽屉容器11；风门36关闭时，送风风道32内的冷风不能流向抽屉容器11。
如图2至图6所示，磁场产生装置40包括第一电磁线圈41、第二电磁线圈42、第一导磁构件43、第二导磁构件44和导磁连接件45。其中，第一电磁线圈41和第二电磁线圈42设置在抽屉20的相对两侧，优选地，第一电磁线圈41和第二电磁线圈42分别设置在抽屉20的顶侧和底侧；进一步优选地，第一电磁线圈41和第二电磁线圈42都设置在抽屉容器11的外侧，以防止第一电磁线圈41和第二电磁线圈42通电过程中产生的热量影响抽屉20内被储藏物的冷藏或冷冻。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，将第一电磁线圈41和第二电磁线圈42分别设置在抽屉20的左侧和右侧；以及选择性地将第一电磁线圈41和第二电磁线圈42设置在抽屉容器11内侧，以使第一电磁线圈41和第二电磁线圈42也能够被进入抽屉容器11内的冷风冷却。
继续参阅图2至图6，第一导磁构件43与第一电磁线圈41相对应，第二导磁构44与第二电磁线圈42相对应。第一导磁构件43和第二导磁构件44用于辅助第一电磁线圈41和第二电磁线圈42在抽屉20内形成强度均匀的磁场，从而使抽屉20内各个区域的食材能够处在相同的磁场环境中，为抽屉20内的被储藏物提供良好的磁场保鲜环境。并且第一导磁构件43和第二导磁构件44的设置，还方便了对第一电磁线圈41和第二电磁线圈42形成磁场的强度的控制，避免了出现抽屉20内局部区域磁场的强度过高或者过低的情形出现。
如图3至图6所示，导磁连接件45将第一导磁构件43和第二导磁构件44连接到一起。
在本发明中，导磁连接件45至少可以防止第一电磁线圈41和第二电磁线圈42的磁场外泄，即，用于将第一电磁线圈41和第二电磁线圈42产生的磁场进行限制，具体地，是将第一电磁线圈41和第二电磁线圈42产生的磁场限制在抽屉20内，以使该磁场尽可能地都作用到抽屉20内的被储藏物 上。因此，本发明通过设置第一导磁构件43、第二导磁构件44和导磁连接件45，提升了第一电磁线圈41和第二电磁线圈42的磁场的利用率。
需要说明的是，第一导磁构件43、第二导磁构件44和导磁连接件45可以是任意可行的导磁构件，例如硅钢片、45坡莫合金、78坡莫合金、超坡莫合金等。
如图5和图6所示，第一导磁构件43、第二导磁构件44和导磁连接件45也被设置在抽屉容器11的外侧，以方便第一导磁构件43、第二导磁构件44和导磁连接件45的安装与固定。当然，本领域技术人员也可以根据需要，将第一导磁构件43、第二导磁构件44和导磁连接件45设置在抽屉容器11的内侧。
如图2和图7所示，在本发明的一些实施例中，检测装置50包括磁体51和磁场感应器52。其中，磁体51设置在抽屉20上，磁场感应器52设置在抽屉容器11上。此外，本领域技术人员也可以根据需要，将磁体51设置在抽屉容器11上，将磁场感应器52设置在抽屉20上。
在本发明的一些实施例中，抽屉20在初始位置(被插进抽屉容器11中)时，磁场感应器52检测到磁体51产生的磁场，使得风冷式制冷设备能够据此判定抽屉20处于初始位置。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，在抽屉20被从抽屉容器11内完全抽出时，再使磁场感应器52检测到磁体51产生的磁场，使得风冷式制冷设备能够据此判定抽屉20被抽出。
在本发明中，磁场感应器52是霍尔开关或干簧管。
图8是本发明另一些实施例中检测装置50的效果示意图。
如图8所示，在本发明的另一些实施例中，检测装置50包括微动开关53，该微动开关53设置在设备本体10(具体是抽屉容器11)上。抽屉20移动到初始位置时，触发微动开关53，从而使风冷式制冷设备据此判定抽屉20处于初始位置。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，将微动开关53设置在抽屉20上。
图9是本发明再一些实施例中风冷式制冷设备的局部原理示意图。
如图9所示，在本发明的再一些实施例中，设备本体10还包括顶盖12、底盖13和侧盖14。其中，顶盖12设置在抽屉容器11的顶侧，并且与抽屉 容器11的顶壁共同限定出第一容纳腔15。底盖13设置在抽屉容器11的底侧，并且与抽屉容器11的底壁共同限定出第二容纳腔16。侧盖14设置在抽屉容器11的左侧和/或右侧，并且与抽屉容器11的侧壁共同限定出连通通道17。其中，第一容纳腔15用于放置第一电磁线圈41和第一导磁构件43。第二容纳腔16用于放置第二电磁线圈42和第二导磁构件44。连通通道17的一端与第一容纳腔15连通，连通通道17的另一端与第二容纳腔16连通。
继续参阅图9，冷风进口111形成在第一容纳腔15的侧壁上。第二容纳腔16的顶壁上设置有底部通孔161，底部通孔161的一端与第二容纳腔16连通，底部通孔161的另一端与抽屉容器11的内腔连通。连通通道17的侧壁上设置有侧部通孔171，侧部通孔171的一端与连通通道17连通，侧部通孔171的另一端与抽屉容器11的内腔连通。
继续参阅图9，冷风从冷风进口111进入第一容纳腔15，冷却第一容纳腔15内的第一电磁线圈41并进入连通通道17。连通通道17内的冷风一部分通过侧部通孔171进入抽屉容器11，吹向抽屉20的侧壁；连通通道17内的冷风另一部分进入第二容纳腔16，然后从底部通孔161进入抽屉容器11，吹向抽屉20的底壁。
或者，本领域技术人员也可以根据需要，省去侧部通孔171，使冷风都从底部通孔161进入抽屉容器11，吹向抽屉20的底壁。
本领域技术人员能够理解的是，在发明的该再一些实施例中，通过使冷风吹向抽屉20的底壁和侧壁，避免了冷风直吹抽屉20内的被储藏物，从而避免了被储藏物的热量损失过来而结冰。
下面参照图2来对本发明中风门36和磁场产生装置40的工作原理进行详细说明。
在本发明中，磁场产生装置40和检测装置50配置成，在检测装置50检测到抽屉20被抽出时，磁场产生装置40断电；以避免磁场产生装置40在抽屉20被抽出时做无用功(即产生的磁场不会作用到抽屉20内的被储藏物上)，从而提升了磁场的利用率，降低了能耗。
进一步，使风门36在磁场产生装置40处于断电状态下时关闭，禁止风冷系统为抽屉20提供冷风；以避免冷风从拉开的抽屉20处逸散到外界，浪费风冷式制冷设备的冷量，从而降低了风冷式制冷设备的能耗。使风门36在磁场产生装置40处于通电状态下时能够打开，以使风冷系统30为抽屉20 提供冷风，冷却抽屉20内的被储藏物。
可选地，风门36在检测装置50检测到抽屉20恢复到初始位置(如图5和图6抽屉20相对于抽屉容器11的位置)，并且在磁场产生装置40通电时打开，以使风冷系统30为抽屉20提供冷风。具体地，当用户将抽屉20从抽出位置推回到图5和图6中抽屉20相对于抽屉容器11的位置时，检测装置50的磁场感应器52或微动开关53被触发，随之使磁场产生装置40通电，开始产生磁场，对抽屉20内的被储藏物进行磁场保鲜。当风冷式制冷设备检测到磁场产生装置40通电时，打开风门36，以使风冷系统30为抽屉20提供冷风。
可选地，在磁场产生装置40处于通电的状态下，如果温度传感器60检测到抽屉20内的温度处于预设高温区间，再使风门36打开，以对抽屉20的被储藏物进行制冷；如果温度传感器60检测到抽屉20内的温度处于预设低温区间，便使风门36关闭，以防止屉20的被储藏物因过度制冷而结冰。
其中，预设高温区域是温度值大于或等于预设温度值的温度区域，预设低温区间是温度值小于或等于预设温度值的温度区域。该预设温度值是能够对被储藏物进行持久保鲜的温度，例如可以是0℃、-1℃、-2℃、-4℃等任意可行的温度值。
进一步可选地，在检测装置50检测到抽屉20恢复到初始位置时，使磁场产生装置40在抽屉20内的温度降低到了预设温度以下时再通电，以使抽屉20被储藏物只在温度较低(尤其是临近结冰温度)时才被磁场产生装置40产生的磁场作用，防止被储藏物结冰，降低了风冷式制冷设备的能耗。
进一步，为了避免磁场产生装置40做无用功，本发明的风冷式制冷设备还包括用于称重抽屉20的称重传感器。只有在称重传感器检测到的重量超过了抽屉20本身的重量时，才允许磁场产生装置40通电，以及允许风门36被打开，从而避免电能的浪费和冷量的浪费。
或者，也可以将称重传感器替换成图像识别单元，以通过图像识别单元来识别抽屉20内是否存在被储藏物。只有在图像识别单元来识别抽屉20内放置有被储藏物时，才允许磁场产生装置40通电，以及允许风门36被打开，从而避免电能的浪费和冷量的浪费。
至此，已经结合前文的多个实施例描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围并不仅限于这些具体实施 例。在不偏离本发明技术原理的前提下，本领域技术人员可以对上述各个实施例中的技术方案进行拆分和组合，也可以对相关技术特征作出等同的更改或替换，凡在本发明的技术构思和/或技术原理之内所做的任何更改、等同替换、改进等都将落入本发明的保护范围之内。
