具体而言,每个发热盘 10上设有电极 11 , 底盘 20为导电底盘, 底盘 20上形成有多个 用于安装发热盘 10的发热盘安装部 21。 灶台板 30上形成有多个发热盘安装孔 31 , 发热盘 10与灶台板 30相连,且发热盘 10的上端穿过发热盘安装孔 31安装在发热盘安装部 21内。 接地端子 40设在发热盘安装孔 31内且与多个发热盘 10中的一个相连。
由此, 根据本发明实施例的发热盘灶台组件, 底盘 20为集成化导电底盘, 避免了每个 发热盘 10底部单独配套使用一个钣金的底壳,通过底盘 20即可实现多个发热盘 10的相互
连接, 只需要一个接地端子 40就可以实现接地连接, 该灶台组件零件少, 加工和釆购成本 低, 并且结构紧凑, 容易装配, 提高了整体生产效率, 极大地降低了组装成本。
考虑到底盘 20需要满足导电要求, 并且具有一定的防锈能力, 根据本发明的一个实施 例, 底盘 20为铸铁底盘。 由此, 铸铁底盘不仅导电性强, 而且防锈性好, 成本低廉。
需要说明的是, 发热盘 10的个数以及大小和排列位置没有特殊限制, 可以根据需要进 行合理调节。 下面以四个发热盘 10为例对本发明的发热盘灶台组件进行详细描述, 其中四 个发热盘 10包括两个大发热盘和两个小发热盘。
将发热盘 10与底盘 20相连的方法没有特殊限制, 可以釆用本领域普通技术人员常用 的装配方式。 如图 1所示, 根据本发明的一个实施例, 每个发热盘 10上设有螺栓 12 , 发 热盘安装部 21形成为沿底盘 20的上表面向上延伸的圆形凸台,且每个发热盘安装部 21上 形成有与螺栓 12适配的安装孔 211 , 螺栓 12穿过安装孔 211并通过多个螺母 121和平垫 122与发热盘安装部 21相连。 可选地, 螺母 121为六角螺母, 螺母 121和平垫 122分别为 两个,螺栓 12设在发热盘 10的中心位置,安装孔 211也设在发热盘安装部 21的圆心位置。 安装时, 将两个螺母 121和两个平垫 122间隔开依次穿过螺栓 12并拧紧在螺栓 12上, 即 可将发热盘 10安装到底盘 20上(如图 2所示)。 该装配方式简单可行, 装配方便, 安装牢 固, 并且成本低廉。
如图 3所示, 根据本发明的一个实施例, 底盘 20上形成有用于避让电极 11的电极避 让孔 22 , 电极 11穿过电极避让孔 22外露在底盘 20的上表面上。 各个电极避让孔 22的形 状与电极 11的形状适配,并且可以根据发热盘 10的安装位置合理布置电极避让孔 22的位 置。 由此, 发热盘 10的电极 11通过电极避让孔 22外露在底盘 20的外侧, 可以方便线束 的连接。
进一步地,根据本发明的一个实施例, 底盘 20上形成有接地端子避让孔 23 ,接地端子 40穿过接地端子避让孔 23外露在底盘 10上。 由此, 可以方便线束从接地端子 40上与电 极 11相连。
为了解决各个发热盘 10在安装之后发生转动的问题, 如图 1所示, 根据本发明的一个 实施例, 每个发热盘 10上设有定位柱 13 , 且每个发热盘安装部 21上形成有与定位柱 13 适配的定位孔 212。 可选地, 每个发热盘 10上可以设有两个定位柱 13 , 每个定位柱 13与 螺栓 11平行且间隔开布置, 定位孔 112设在发热盘安装部 21的圆形凸台的周边位置。 由 此, 通过定位柱 13与定位孔 212的配合, 可以实现每个发热盘 10的固定, 有效防止发热 盘 10在安装之后发生转动。
由于灶台板 30变形可导致灶台板 30 ^发热盘 10之间产生较大的配合间隙,用户使用
烤箱进行煮食时经常有水从锅具溢出到灶台板 30上, 存储在灶台板 30上面的水将从灶台 板 30与发热盘 10之间的间隙中渗入烤箱内部, 从而引起漏电的安全问题。 因此, 根据本 发明的一个实施例, 如图 3所示, 底盘 20的多个发热盘安装部 21之间形成有加强筋 24。 可选地, 加强筋 24设在每两个相邻的发热盘安装部 21之间。 关于加强筋 24的形状和成型 方法没有特殊限制, 其形状可以根据各个发热盘安装部 21的排布进行调节, 其成型方法可 以通过冲压成型, 也可通过本领域普通技术人员常用的方法形成, 此处不再赘述。 由此, 通过在底盘 20上形成加强筋 24 , 可以提高发热盘灶台组件的整体结构强度, 防止该组件 在安装运输和用于烤箱工作时发生扭曲变形,并且进一步防止了灶台板 30由于扭曲变形而 导致的爆瓷现象, 提高了产品的外观品质。
考虑到发热盘灶台组件需要通过线束与烤箱等设备相连, 可选地, 根据本发明的一个 实施例, 加强筋 24上形成有多个束线孔 241。 具体地, 束线孔 241至少为两个。 由此, 可 以方便发热盘灶台组件的线路的排布。
根据本发明的一个实施例, 如图 1所示, 灶台板 30的外周形成有沿灶台板 30的上表 面向上延伸的侧板 32 , 底盘 20的左右两侧分别形成有沿底盘 20的上表面向上延伸的左反 射板 25和右反射板 26 (如图 4所示 )。 由此, 左反射板 25和右反射板 26不仅能够进一步 提高底盘 20的强度, 而且能够阻挡发热盘 10的产生的热量向灶台板 30的侧板 32进行热 辐射, 可以降低侧板 32的表面温度, 提高产品的安全性能。
可选地, 根据本发明的一个实施例, 左反射板 25和右反射板 26与底盘 20—体形成。 由此,一体形成的结构能够进一步保证底盘 20的整体结构稳定性, 并且制备方便, 可以进 一步降低成本。
另外, 由于灶台板 30变形可导致灶台板 30与发热盘 10之间产生较大的配合间隙, 用 户使用烤箱进行煮食时经常有水从锅具溢出到灶台板 30上, 存储在灶台板 30上面的水将 从灶台板 30与发热盘 10之间的间隙中渗入烤箱内部, 从而引起漏电的安全问题。 因此, 如图 1所示, 根据本发明的一个实施例, 底盘 20与灶台板 30之间设有隔热板 50 , 每个发 热盘 10穿过隔热板 50与底盘 20相连。 具体地, 隔热板 50上形成有与电极 11、 螺栓 12 以及定位柱 13适配的孔道, 其主要目的是为了方便发热盘 10与底盘 20和灶台板 30的连 接, 此处不再详细描述。 由此, 通过设置隔热板 50 , 能够提高灶台板 30与发热盘 30之间 的密封性能,从而阻止灶台板 30上面的水从灶台板 30与发热盘 10之间的间隙中渗入烤箱 内部, 极大地提高了产品的安全性能。
其中, 隔热板 50的制备材料没有特殊限制, 只要可以起到上述作用即可。 考虑到成本 问题, 根据本发明的一个实施例, 隔热板 50为隔热棉。 由此, 隔热板 50材料来源广泛,
而且成型方便, 防水效果好。
下面结合图 6至图 8具体描述根据本发明第二方面实施例的发热盘灶台烤箱及其线束 安装过程。
如图 6和图 7所示, 才艮据本发明实施例的发热盘灶台烤箱, 包括: 箱体 60和才艮据上述 实施例所述的发热盘灶台组件 70。
具体地, 箱体 60内设有发热管接地端子 61 , 发热盘灶台组件 70设在箱体 60上, 且发 热盘灶台组件 70的接地端子 40与发热管接地端子 61电性连接。
由此, 根据本发明实施例的发热盘灶台烤箱, 底盘 20为集成化导电底盘, 避免了每个 发热盘 10底部单独配套使用一个钣金的底壳,通过底盘 20即可实现多个发热盘 10的相互 连接, 即通过底盘 20可以替代地线分别连接多个发热盘 10 , 只需要一个接地端子 40就可 以实现接地连接, 减少了多余的地线, 降低了成本, 并且该烤箱的接地方式更加安全可靠, 减少了接地不良的安全隐患, 提高了产品的整体安全性能。
其中, 接地端子 40与发热管接地端子 61的电性连接可以通过线束实现, 也就是说, 发热盘灶台组件 70的接地端子 40与发热管接地端子 61通过线束连接。 具体地, 线束的一 端与接地端子 40相连, 另一端穿过加强筋 24上的束线孔 241与发热管接地端子 61相连。
进一步地, 根据本发明的一个实施例, 箱体 60内设有温度控制器 62 , 温度控制器 62 检测箱体 60内的温度并在箱体 60内温度达到预定温度时切断烤箱的电流。 由此, 当烤箱 内部温度过高时, 温度控制器 62可及时切断烤箱部分的输入电流, 当烤箱内部温度恢复到 了正常温度时, 温度控制器 62可立即打开烤箱部分的输入电流, 从而有效地保护了烤箱的 正常工作, 同时避免了烤箱温度过高而造成的电路故障, 进一步提高了烤箱的使用安全性。
下面参照图 7和图 8具体描述才艮据本发明实施例的发热盘灶台烤箱的线束安装过程。 才艮据本发明实施例的发热盘灶台烤箱在装配线束时,首先,将铸铁发热盘转换开关 601、 烤箱能量控制器 602、 烤箱功能开关 603、 灶台指示灯 604、 烤箱指示灯 605、 机 ¾式定时 器 606固定在控制板固定框 607上, 实现这些电器控制元件的预先装配。
然后, 将炉灯 608、 红外发热管 609、 上发热管 610、 热风发热管 611、 下发热管 612、 热风电机 613、 旋转烧烤电机 614和温度控制器 615分别固定至腔体组件 616上, 完成烤 箱内部电器元件的预先装配。
接着, 如图 8所示将线束和发热盘 10的电极 11连接。 完成线束与发热盘灶台组件连 接之后将线束与铸铁发热盘转换开关 601、 烤箱能量控制器 602、 烤箱功能开关 603、 灶台 指示灯 604、 烤箱指示灯 605和机 ^¾式定时器 606等电器控制元件连接。
其中, 铸铁发热盘转换开关 601、 烤箱能量控制器 602、 烤箱功能开关 603和机械式定
时器 606均通过功能旋钮 617进行控制, 按顺时针方向转动, 可逐渐加大与之相匹配的电 器元件的设定的发热功率和工作时间。
接着, 将线束与炉灯 608、 红外发热管 609、 上发热管 610、 热风发热管 611、 下发热 管 612、 热风电机 61 3、 旋转烧烤电机 614和温度控制器 615等电器功能元件连接, 并把线 束 9的 3根火线、 1根地线和 1根零线连接到接线盒 618的端子上。 其中, Ll、 L2、 L3分 别代表火线 1、 火线 2和火线 3 , E代表地线, N代表零线。
由此, 可以实现发热盘灶台烤箱的线束安装。
总而言之, 根据本发明实施例的发热盘灶台烤箱, 只需要一个接地端子 40就可以实现 接地连接, 减少了多余的地线, 降低了成本, 并且该烤箱的接地方式更加安全可靠, 减少 了接地不良的安全隐患, 提高了产品的整体安全性能。
