Abstract
温度传感器3和将传感器与电路相连的导电体4分布在构成炊具底部1的壁和一通过冷压固定在所述壁上的穿孔板5之间。
Description
本发明涉及一种炊具,如长柄深平底锅或长柄平底小锅,它有一个底部和一个侧壁。
美国专利5,441,344描述了一种在炊具底部内装有一温度传感器如一热电偶的炊具。
此热电偶传送一随温度而变化的电压信号。
此电压由一电路处理,此电路将此电压转变为温度信号,显示在炊具的手柄上。
将温度传感器装在炊具底部内是一项复杂的工作,它增加了生产成本并尤其是在水洗时带来防潮问题,使得此传感器以及与其相连的导电体必须绝对防潮。
本发明的目的就是为了解决上述问题。
因此本发明是针对一种有一底部、一侧壁以及在所述底部内装有一温度传感器的炊具,其中温度传感器与一电路相连,电路用以处理由传感器测量到的参数并将温度显示出来。
根据本发明,上述炊具的特征为:温度传感器及将传感器与电路相连的导电体在组成炊具底部的壁和一通过冷压固定在所述壁上的穿孔板之间延伸。
炊具的底部和侧壁由铝盘制成,而由冷压固定的穿孔板最好由不锈钢制成。
通过冷压将穿孔板固定在炊具底部的方法在如本申请人的法国专利2 693 894和2 711 051中描述。
在上述方法应用过程中,炊具底部的金属进入穿孔板的孔中,这样能确保穿孔板相对炊具底部金属良好固定。
根据本发明,通过冷压固定到炊具底部上的穿孔板同时具有下面两种功能:
-它使炊具底部能更好地抵抗由所述底部的热膨胀的突然变化而产生的变形;以及
-它能防止温度传感器及与其连接的导电体受潮、受机械冲击及与炉架上的炉子直接接触。
温度传感器可以是一个热电偶、一个负温度系数(NTC)电阻器、一个正温度系数(PTC)电阻器、一个PT100或一个热敏元件等。
在使用一个热电偶的情况下,连有此传感器的电路在温度变化时检测出一个电压变化。
在其它情况下,此电路检测出一个阻抗变化的欧姆值。
在本发明一个优选实施例中,所述传感器位于接近底部中心的底部外表面上,所述穿孔板的一部分盖住所述传感器及所述底部外表面的中心部,而穿孔板的一细长部盖住所述导电体并沿底部外表面径向延伸并至少部分伸至炊具的侧壁上。
传感器和导体最好还装在一槽中。
此槽形成在构成炊具底部的壁的外表面上是有利的。
在本发明一个优选实施例中,电路和温度显示装置装在一个固定在炊具手柄上的部件中。
此部件最好可拆除地连接到手柄上,以便在将炊具放入一洗碗桶或洗碟机之前可将部件从手柄上取下。
本发明的其它特征及优点将通过以下描述而更显而易见。
附图以非限定性示例方式给出,其中:
图1示出了一个金属盘的平面图,其中盘在受压前已经固定了一个盖住一温度传感器和连接导体的平板;
图2是沿图1中II-II线的一个剖视图,示意性地示出了在一个盘压成一个容器之前将穿孔板和热传感器固定在盘上的方法;
图3和图4与图1和图2相似,示出了将此板和传感器固定在一已经压好的炊具上;
图5是一个在通过受压固定前穿孔板、传感器和炊具底部的局部剖视放大图;
图6与图5相似,示出了此组件在通过受压固定后的情况;
图7示出了盖住热传感器的穿孔板的局部图;
图8是一个长柄平底小锅的剖视图,其中小锅的手柄带有一个腔室,腔室包括一个电路和温度显示装置;以及
图9与图8相似,示出了电子部件能从此手柄上拆下。
图3示出了一个长柄平底小锅,它有一个底部1以及一个侧壁2,小锅由一个盘如铝盘制成。
一温度传感器3装在底部1内。此传感器3连到一个电路上,此电路用以处理由传感器3测到的参数并显示温度。
根据本发明,温度传感器3和将传感器3与电路相连的导电体4在构成炊具底部的壁1和一穿孔板5之间延伸,此穿孔板5由不锈钢制成,通过如冷压固定在上述的壁1上。
在所示的例子中,传感器3位于接近底部1中心的其外面上。
穿孔板5有一个圆形部5a和一个细长部5b,其中圆形部5a盖住传感器3以及底部1外表面的中心部,而细长部5b盖住导电体4并沿底部1外表面径向延伸,而且至少伸至平底小锅的侧壁2上。
图5至图7示出了传感器3和导体4容装在一槽6中,槽6位于组成炊具底部1的壁的外表面上1a。
在图8和图9所示的例子中,电路和温度显示装置装在一部件7中,部件7可拆除地连接到平底小锅的手柄8上,以便在将平底小锅放入洗碟机中之前可将部件7取下。
在炊具底部1受压之前和之后穿孔板5固定在其上的详细情况可参考法国专利2 693 894和2 711 051的说明书。
在冷压操作后,穿孔板5尤其如图6所示紧密地连接在底部1的表面上并能防水地盖住传感器3以及将传感器3连至电子部件7上的导电体4上。
在此状态中,传感器3完全装入炊具底部内,并且将以最优方式测出其温度。
当然,本发明不限于方才所述的实施例,而是在不背离本发明范围的前提可以进行许多修改。
相应地,温度显示电子部件可以固定在一可从炊具上拆下的手柄中,而不用将部件本身从炊具手柄上拆下。
