Description

加热装置及冰箱 技术领域
本发明涉及食品加热领域，特别是涉及一种加热装置及具有该加热装置的冰箱。
背景技术
为了便于用户冷冻和加热食物，现有技术一般通过在冰箱中设置加热装置或微波装置来解冻食物。不同的加热方式，解冻效果并不一样。本申请的申请人在之前申请了一种解冻效率高、解冻均匀且可保证食物品质的解冻装置，该解冻装置利用电磁波对待处理进行加热。
通常情况下，说到电磁波大家都会认为其会对人身健康有害。作为电磁波，的确或多或少都会产生辐射，尤其现在的家用电器日益增多，其电磁污染越来越得到人们的重视，若人体长期暴露于强力电磁场下，则可能易患癌症病变。因此，防电磁干扰已是必备而且势在必行的工作。
发明内容
通常情况下人们对电磁波的屏蔽原理不是太了解，认为只要是用微波来实现某工作的电器或者工具都认为其具有电磁辐射，都会对人体产生危害，其实这种概念是有误的。因为真正影响屏蔽体屏蔽效能的只有两个因素：一个是整个屏蔽体表面必须是导电连续的，另一个是不能有直接穿透屏蔽体的导体。屏蔽体上如果有很多导电不连续点，屏蔽体不同部分结合处就会形成不导电缝隙。这些不导电的缝隙就会产生电磁泄漏，如同流体会从容器上的缝隙上泄漏一样。
为此，本发明第一方面的一个目的旨在克服现有技术中的至少一个缺陷，提供一种能够有效地减少甚至避免电磁泄漏的加热装置。
本发明第一方面的一个进一步的目的是进一步避免加热装置的电磁泄漏。
本发明第一方面的另一个进一步的目的是进一步提高加热装置使用的安全性。
根据本发明的第一方面，本发明提供一种加热装置，其包括：
筒体，其内限定有用于放置待处理物的加热腔室，且具有位于其前侧的取放开口；
门体，用于开闭所述筒体的取放开口；
电磁加热装置，用于向所述加热腔室内产生电磁波，以加热所述加热腔室内的待处理物；以及
磁性件，设置于所述门体或所述筒体上，用于促使所述门体和所述筒体相互吸引，以在所述门体处于封闭所述取放开口的关闭状态时使得所述门体和所述筒体紧密地电性接触，从而形成连续导电的屏蔽体。
可选地，所述门体具有用于与所述筒体电性连接以密闭所述加热腔室的金属端板，所述磁性件设置于所述金属端板的背离所述筒体的一侧。
可选地，所述门体还包括由所述金属端板朝靠近所述筒体的方向凸出并与所述金属端板电连接的导电连接件，所述导电连接件配置成在所述门体处于关闭状态时与所述筒体电性接触，以通过所述导电连接件将所述金属端板和所述筒体电性连接。
可选地，所述导电连接件为朝后凸出于所述金属端板后壁的金属凸块或导电胶条。
可选地，所述金属端板的与所述导电连接件前后相对应的前侧位置形成向后凹陷的凹坑，所述磁性件容置在所述凹坑中。
可选地，所述门体还包括前后设置的前端盖和后端板，所述金属端板位于所述前端盖和所述后端板之间；且
所述后端板上开设有第一通孔，所述导电连接件从所述第一通孔向后伸出，从而在所述门体处于关闭状态时与所述筒体电性连接。
可选地，所述前端盖的后侧设有安装部，所述磁性件通过卡接的方式安装在所述安装部中。
可选地，所述导电连接件为与所述金属端板一体成型或与所述金属端板固定连接的导电弹片，所述导电弹片配置成在所述门体处于关闭状态时与所述筒体的前向表面电性接触。
可选地，所述加热装置还包括：
滑轨组件，包括设置于所述筒体内部并与所述筒体电性连接的定轨、以及可操作地沿所述定轨滑动，并与所述定轨电性接触的滑轨；其中
所述导电连接件为与所述金属端板一体成型或与所述金属端板固定连接的导电弹片，所述导电弹片的一端与所述金属端板电性连接，另一端至少 在所述门体处于关闭状态时与所述定轨或所述滑轨电性连接，进而与所述筒体电性连接。
根据本发明的第二方面，本发明提供一种冰箱，其包括：
箱体，其内限定有至少一个储物间室；以及
上述任一所述的加热装置，设置于其中一个所述储物间室中。
本发明的加热装置利用电磁加热装置对待处理物进行加热，加热效率高、加热均匀且可保证食物品质。加热装置具有筒体和门体两个相对独立的部件，门体关闭时，筒体与门体的结合位置处难免会形成一定的间隙，该间隙就是导致加热装置不能形成连续导电的屏蔽体从而产生电磁泄漏的主要原因。因此，本发明通过在门体或筒体上特别设计磁性件，使得门体和筒体相互吸引，从而在门体处于关闭状态时使得门体和筒体紧密地电性接触，一方面减小了门体与筒体之间的间隙大小，减少了电磁泄漏量，另一方面，还有助于门体和筒体形成连续导电的屏蔽体，阻止了电磁波经门体与筒体之间可能存在的间隙射出，有效地屏蔽了电磁辐射、消除了电磁辐射对人体的伤害。
进一步地，本发明还特别设计有导电连接件，即使筒体与门体之间仍然存在间隙的情况下仍然能够使得筒体与门体之间形成电连接，从而在加热时形成连续导电的屏蔽体，进一步阻止了电磁波经该间隙射出，有效地屏蔽了电磁辐射、消除了电磁辐射对人体的伤害。
进一步地，本发明的门体还包括前端盖和后端板，具有导电性能的金属端板位于前端盖和后端板之间，由此，用户在操作门体时不会触碰到导电的金属端板，进一步提高了加热装置使用的安全性。
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
本发明首先提供一种加热装置，用于对待处理物进行加热、解冻等。该加热装置可以单独使用，也可以结合冰箱或其他装置一起使用。
图1是根据本发明一个实施例的加热装置的示意性部分结构分解图。参见图1，本发明的加热装置10包括筒体110、门体120以及电磁加热装置(图1中未示出)。筒体110内限定有用于放置待处理物的加热腔室，且具有位于其前侧的取放开口。门体120用于开闭筒体110的取放开口。具体地，当门体120封闭筒体110的取放开口时处于关闭状态，当门体120处于打开筒体110的取放开口时处于打开状态。门体120可通过适当的方式(例如扣合、抽拉等等)与筒体110安装在一起。
电磁加热装置用于向加热腔室内产生电磁波，以对加热腔室内的待处理物进行加热。至少部分电磁加热装置设置于筒体110内。电磁加热装置产生的电磁波可以为射频波、微波等具有合适波长的电磁波。这种利用电磁波对待处理物进行加热的方式加热效率高、加热均匀且可保证食物品质。
图2是根据本发明一个实施例的门体的示意性分解图。为了便于理解，图2中还示出了与门体相连的抽屉。特别地，加热装置10还包括磁性件160，磁性件160设置于门体120或筒体110上，用于促使门体120和筒体110相互吸引，以在门体120处于封闭筒体110的取放开口的关闭状态时使得门体120和筒体110紧密地电性接触，从而形成连续导电的屏蔽体。
本发明通过在门体120或筒体110上特别设计磁性件160，使得门体120和筒体110相互吸引，从而在门体120处于关闭状态时使得门体120和筒体110紧密地电性接触，一方面减小了门体120与筒体110之间的间隙大小，减少了电磁泄漏量，另一方面，还有助于门体120和筒体110形成连续导电 的屏蔽体，阻止了电磁波经门体120与筒体110之间可能存在的间隙射出，有效地屏蔽了电磁辐射、消除了电磁辐射对人体的伤害。
在一些实施例中，门体120具有用于与筒体110电性连接以密闭筒体110内的加热腔室的金属端板121。在门体120处于关闭状态时，门体120的金属端板121封闭筒体110的取放开口，从而封闭筒体110内的加热腔室。筒体110可以为金属筒体，也可以为在其上设置例如可以为导电涂层、导电金属网等的电磁屏蔽特征的非金属筒体。
进一步地，磁性件160可设置于金属端板121的背离筒体110的一侧，由此，既可保证磁性件160安装的稳固性，又能够通过磁性件160确保门体120与筒体110紧密相吸。
在一些实施例中，门体120还包括由金属端板121朝靠近筒体110的方向(即向后)凸出并与金属端板121电连接的导电连接件122，导电连接件122配置成在门体120处于关闭状态时与筒体110电性接触，以通过导电连接件122将金属端板121和筒体110电性连接。
本发明通过在门体120上特别设计导电连接件122，即使门体120处于关闭状态时，筒体110与门体120之间仍然存在间隙的情况下仍然能够保证筒体110与门体120之间形成电连接，从而在加热时形成连续导电的屏蔽体，进一步阻止了电磁波经该间隙射出，有效地屏蔽了电磁辐射、消除了电磁辐射对人体的伤害。
进一步地，本发明只需由门体120的金属端板121向靠近筒体110的方向凸出延伸的导电连接件122即可，无需在门体120和筒体110之间的整个间隙中全部设置导电材料，一方面可避免填充的导电材料与门体或筒体之间再次形成间隙，另一方面还节省了大量的材料和部分制造工序，简化了加热装置10的结构，降低了其成本。
在一些实施例中，导电连接件122为朝后凸出于金属端板121后壁的金属凸块或导电胶条。具体地，导电连接件122可以为与金属端板121一体成型的金属凸块，该金属凸块从金属端板121的后向表面朝向靠近筒体110的方向(即朝后)凸出延伸。在另一些实施例中，导电连接件122可以为与金属端板121固定连接的金属凸块，该金属凸块可以通过螺钉连接、焊接、铆接等合适的方式固定在金属端板121的朝向筒体110的表面(即后向表面)。在又一些实施例中，导电连接件122可以为通过导电胶固定在金属端板121上的导电胶条。在这些实施例中，对金属凸块或导电胶条的形状并不做限制， 其可以为长条形、方形、圆形或其他合适的形状。
本发明的导电连接件122可直接采用金属凸块或导电胶条等，并直接与筒体110的位于其取放开口周缘且朝向门体120的外端面电性接触，省去了其他复杂的连接结构、支撑结构或装配结构，进一步简化了加热装置10的结构，降低了其成本。
图3是根据本发明一个实施例的加热装置的示意性剖视图，图4是图3中部分A的示意性放大图。在一些实施例中，金属端板121的与导电连接件122前后相对应的前侧位置形成向后凹陷的凹坑1211，磁性件160容置在凹坑1211中。也就是说，在这些实施例中，磁性件160可隔着导电连接件122吸引筒体110。
进一步地，门体120还包括前后设置的前端盖123和后端板124，端板121位于前端盖123和后端板124之间，由此，用户在操作门体120时不会触碰到导电的端板121，进一步提高了加热装置10使用的安全性。
具体地，在一些实施例中，前端盖123和后端板124之间可通过卡接和/或螺钉连接等方式紧固连接，端板121夹持在前端盖123和后端板124之间。端板121与前端盖123或后端板124可以具有连接关系(例如卡接、螺钉连接或其他合适的连接关系)，也可以不具有连接关系，仅靠前端盖123和后端板124的夹持力即可得到稳定的支撑。在另一些实施例中，前端盖123与端板121可以先按照合适的方式预装在一起，例如，塑料材质的前端盖123可以注塑在端板121的前侧，然后注塑在端板121前侧的前端盖123再与后端板124进行装配。在一些实施例中，加热装置10还包括用于承载待处理物的抽屉140，抽屉140连接在门体120的后侧，并经取放开口可推拉地设置于筒体110中。后端板124与抽屉140一体成型或固定连接。
更进一步地，后端板124上开设有第一通孔1241，导电连接件122从第一通孔1241向后伸出，从而在门体120处于关闭状态时允许导电连接件122与筒体110电性接触。第一通孔1241的形状可与导电连接件122的形状保持一致，以提升门体120的外形美观。
在一些实施例中，前端盖123的后侧设有安装部1231，磁性件160通过卡接的方式安装在安装部1231中。当前端盖123、金属端板121和后端板124装配在一起后，卡接在安装部1231中的磁性件160容置在凹坑1211中。
图5是根据本发明另一个实施例的门体与抽屉的示意性结构图，图6是图5中部分B的示意性放大图。在一些实施例中，导电连接件122为与金属 端板121一体成型或与金属端板121固定连接的导电弹片，该导电弹片配置成在门体120处于关闭状态时与筒体110的前向表面电性接触。具体地，导电弹片与金属端板121一体成型。此时导电弹片可以为与金属端板121材质相同的金属弹片。在另一些实施例中，导电弹片也可通过螺钉连接、焊接或铆接的方式固定在金属端板121上。
具体地，该导电弹片可包括至少一个平直的端部区段1221以及由端部区段1221向朝向筒体110的方向凸出拱起的拱形区段1222。具体地，在图5和图6所示实施例中，导电弹片包括两个端部区段1221，拱形区段1222设置在两个端部区段1221之间。
进一步地，至少其中一个端部区段1221通过螺钉与金属端板121紧固连接，拱形区段1222配置成在门体120处于关闭状态时与筒体110的前向表面电性接触，以通过导电弹片将金属端板121和筒体110电性连接，从而进一步简化了加热装置10的结构，降低了其成本。
金属端板121上可开设有第二通孔1212，导电弹片具有两个端部区段1221，导电弹片的拱形区段1222位于其两个端部区段1221之间。导电弹片122的两个端部区段1221均位于金属端板121的背离筒体110的前侧，导电弹片的拱形区段1222穿过第二通孔1211向后伸出。导电弹片与金属端板121的此种结构关系和连接关系可使得二者的电连接更加可靠，也使得导电弹片的安装更加稳固。
图7是根据本发明又一个实施例的加热装置的示意性剖视图，图8是图7中部分C的示意性放大图。在一些实施例中，加热装置10还包括滑轨组件150，滑轨组件150包括设置于筒体110内部并与筒体110电性连接的定轨151、以及可操作地沿定轨151滑动，并与定轨151电性接触的滑轨152。门体120可通过滑轨组件沿前后方向可滑动地与筒体110相连。在这些实施例中，导电连接件122可以为与金属端板121一体成型或与金属端板121固定连接的导电弹片，该导电弹片的一端与金属端板121电性连接，另一端至少在门体120处于关闭状态时与定轨151或滑轨152电性连接，进而与筒体110电性连接。
进一步地，滑轨152可设置于抽屉140的外部，导电弹片的另一端与滑轨152电性连接，进而通过滑轨152和定轨151与筒体110电性连接。由此，无论门体120处于何种状态，导电弹片122都会通过滑轨152、定轨151与筒体110保持稳定可靠的电性连接，提高了加热装置10电磁屏蔽的可靠性 和加热装置10使用的安全性。
图9是根据本发明一个实施例的筒体与部分电磁解冻装置的示意性结构分解图。在本发明的一些实施例中，筒体110可包括金属本体以及贴设于金属本体前侧的金属装饰件112，金属装饰件112例如可以为钣金件，其与金属本体之间静电接触。金属装饰件112的前向表面形成筒体110的前向表面。金属本体可包括金属下盖1112和覆盖在金属下盖1112上的金属上盖1111，金属下盖1112具有两个横向侧板、底板以及后板。
在本发明的一些实施例中，电磁加热装置包括电磁发生模块131(参见图10)、辐射天线132和天线罩133。电磁发生模块131用于产生电磁波信号。辐射天线132与电磁发生模块131电连接，以根据电磁发生模块131产生的电磁波信号在加热腔室内产生相应频率的电磁波，从而对加热腔室内的待处理物进行加热。天线罩133由绝缘材料制成，且设置于筒体110中，并将筒体110内的加热腔室分隔为加热室1131和电器室1132，其中，待处理物和辐射天线132分别设置于加热室1131和电器室1132，以将待处理物和辐射天线132分隔开，防止抽屉140拉出后辐射天线132外露影响用户的使用体验，同时也避免辐射天线132脏污或误触损坏。电磁发生模块131可设置于筒体110的外部。
进一步地，天线罩133可由非透明材料制成，以减少电磁波在天线罩133处的电磁损耗，进而提高对待处理物的加热速率。
进一步地，天线罩133可设置于筒体110内的底部，且包括水平延伸的隔板1331和由隔板1331的四周边缘向下延伸的裙部1332。裙部1332可与筒体110固定连接。辐射天线132可通过卡接或其他合适的方式固定在隔板1331的下侧。辐射天线132也可以作为一种液体的金属材料直接电镀在隔板1331上。
在一些实施例中，电磁加热装置还包括信号处理及测控电路134，信号处理及测控电路134与电磁发生模块131电连接，用于对电磁发生模块131产生的电磁波的特定特征进行检测和调节。辐射天线132可连接至信号处理及测控电路134的电路板。具体地，信号处理及测控电路134可设置于电器室1132中，并位于辐射天线132的后侧。信号处理及测控电路134可通过支撑架135支撑在电器室1132中。
基于上述任一实施例的加热装置10，本发明还提供一种冰箱。图10是根据本发明一个实施例的冰箱的示意性结构图，参见图10，本发明的冰箱1 包括箱体20，箱体20内限定有至少一个储物间室21。冰箱1还包括用于分别开闭各个储物间室的取放口的间室门体、制冷***等。
特别地，冰箱1还包括上述任一实施例所描述的加热装置10，其设置于其中一个储物间室21中。从冰箱冷冻室取出的待处理物可通过加热装置10来加热，加热效果较好，使用方便。
在一些实施例中，箱体20内还限定有用于放置压缩机的压缩机仓23。压缩机仓23通常位于箱体20的后侧底部，并由箱体20的外壳和底钢总成限定而成。电磁发生模块131可设置于压缩机仓23内，并通过线缆136与信号处理及测控电路134相连，进而通过信号处理及测控电路134与辐射天线132电连接。
进一步地，压缩机仓23内还设有支架231，电磁发生模块131支撑在支架231上。
本领域技术人员应理解，在没有特殊说明的情况下，本发明实施例中所称的“顶”、“底”、“内”、“外”、“横”、“前”、“后”等用于表示方位或位置关系的用语是以加热装置10和冰箱1的实际使用状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或部件必须具有特定的方位，因此不能理解为对本发明的限制。
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。
