[1] 技术领域
[2] 本发明涉及一种无线信号传输装置及传输方法， 特别是涉及一种用于电热水壶 的无线信号传输装置及传输方法。
[3] 背景技术
[4] 目前市面上生产和销售的电源分离式电热水壶、 蒸锅等电炊具产品， 其机身与 基座之间通常都是采用三点或五点的电连接器来进行连接。 其中， 三点的电连 接器， 只能起到机身与基座之间电源连接的功能。 五点电连接器中的三点用于 电源连接， 另外两个点作为控制信号传输用， 主要是机械接触式， 釆用这种五 点电连接器制成的产品， 可以自由地将控制功能按键和显示装置设置在机身或 底座上， 在釆用 360度可旋转式电连接器吋， 仍能使电器的机体与底座中的控制 信号互相进行通信。 2009年 8月 5日公幵的中国发明专利申请 ZL200910105150.8" 电连接器"中控制信号的传输釆用在凸形连接器和凹形连接器内分别设置无线传 输装置， 无线传输装置之间配对并进行信号的无线传输， 其利用红外线发射接 收二极管进行信号的无线传输， 并要求红外线发射接收二极管配对使用和位置 上相对应， 这样有效地解决了五点连接器中机械接触式信号传输容易产生误差 的缺点， 但依然存在以下不足： 就是当凸形连接器和凹形连接器的内部空间较 小时， 设计连接器需要花费较大精力来解决红外线发射接收二极管摆放位置的 问题。
[5] 发明内容
[6] 本发明要解决的技术问题是提供一种可以设置在机体底盖和基座上壳的的任何 位置， 也不需要将无线传输装置的红外线发射接收二极管设置在下连接器和上 连接器内的无线信号传输装置及传输方法。
[7] 为解决上述技术问题， 本发明釆用如下技术方案： 一种无线信号传输装置， 包 括通过上连接器和下连接器连接的机体和基座， 所述机体内设有上控制电路板 ， 所述基座内设有下控制电路板， 所述机体上设置有上发射接收装置， 所述基 座上设置有下发射接收装置， 所述上发射接收装置通过导线与上控制电路板相 连， 所述下发射接收装置通过导线与下控制电路板相连， 所述上发射接收装置 设置在机体的底盖上， 所述下发射接收装置设置在基座上壳上， 所述机体和底 座上分别设置有位置上互相对应的光反射结构， 所述上发射接收装置和下发射 接收装置的发射接收头部分别设置在机体和底座上的光反射结构中。
[8] 本发明所述机体底盖上设置有透光材料结构或通孔， 所述上发射接收装置的 发射接收头部位置与透光材料结构对应或处于通孔中。

[10] 本发明所述下发射接收装置设置在基座上壳上， 基座上壳设置有透光材料结构 或通孔， 所述下发射接收装置的发射接收头部位置与透光材料结构对应或处于 通孔中。
[11] 本发明所述底座上设置的光反射结构是在底座上壳外表面上设置光反射材料涂 层或底座上壳外表面采用光反射材料层或设置具有光反射作用的凹形反射槽。
[12] 本发明所述机体和基座上的 H形反射槽和光反射材料结构是以上连接器和下连 接器中心为圆心的圆环形， 所述的凹形反射槽的横截面为半圆弧形或矩形， 所 述光反射材料层为表面光滑的金属材料、 塑料或塑料镀膜材料层。
[13] 本发明所述上发射接收装置和下发射接收装置是配对的红外线信号通信装置。
[14] 本发明所述上发射接收装置和下发射接收装置是红外线发射二极管和红外线接 收二极管或红外线发射接收二极管封装在一起的红外线发射接收装置。
[15] 本发明所述上连接器和下连接器为 360度旋转式结构连接器。
[16] 本发明无线信号传输装置的传输方法， 包括以下步骤：
[17] (1) 在采用 360度旋转式电连接器的机体和底座上设置光反射材料和结构。
[18] (2) 将上发射接收装置和下发射接收装置的发射接收头部设置在光反射结构 中。
[19] (3) 当机体与基座通过上下连接器连接在一起吋， 机体和底座上设置的光反 射材料和结构位置上对应。
[20] (4) 当机体底盖上的上发射接收装置发出光控制信号吋。
[21] (5) 光控制信号通过机体底盖到达基座上壳的光反射部位或材料上， 经过反 射， 光控制信号又返回到机体底盖的光反射部位或材料上。
[22] (6) 光控制信号在机体底盖和基座上壳的光反射部位或材料上， 经过多次反 复反射， 最后到达基座上壳的下发射接收装置上， 完成控制动作， 这样完成了 控制信号的整个传输过程。
[23] (7) 相反， 当基座上壳的下发射接收装置发出光控制信号吋， 光控制信号通 过基座上壳到达机体底盖的光反射部位或材料上， 经过反射， 光控制信号又返 回到基座上壳的光反射部位或材料上。
[24] (8) 光控制信号在机体底盖和基座上壳的光反射部位或材料上， 经过多次反 复反射， 最后到达机体底盖的上发射接收装置上， 完成控制动作， 这样完成了 控制信号的整个传输过程。
[25] 本发明与现有技术相比， 釆用红外线信号的非接触式信号传输方式， 解决了现 有技术中电连接器因触点的氧化而导致产生较大的接触电阻后， 可能产生测量 所得数据信号在传输过程中出现误差， 造成控制的错误问题。 同吋， 将上发射 接收装置设置在机体的底盖上， 下发射接收装置设置在基座上壳上， 并在机体 和底座上设置光反射结构， 使上发射接收装置和下发射接收装置设置可以不需 在位置上点对点对应， 其位置设置更为方便， 也不再需要装置在上、 下连接器 内， 减小了电连接器的设计难度， 也降低了成本， 方便于生产。 当机体与基座 采用无线传输信号的设计方案时， 发射接收装置可分别作为美观装饰物， 发射 接收装置配对灵活地设置在机体与基座上的任何位置， 优化了产品的外观设计

[38] 具体实施方式
[39] 以下结合附图和实施例对本发明作进一步的描述。
[40] 如图 1、 图 1-1、 图 1-2、 图 2、 图 3、 图 4所示， 其为本发明所公开的无线信号传 输装置和传输方法的实施例； 如图 5、 图 5-1、 图 6所示， 其为本发明所公开的无 线信号传输装置的另一个实施例。
[41] 具体实施例一：
[42] 如图 1、 图 1-1、 图 1-2、 图 2、 图 3、 图 4所示， 其为本发明中无线信号传输装置 和传输方法的第一种优选实施方案。 以本发明"用于电子电热水壶上， 机体与基 座上设有光反射结构 "为例， 该方案包括通过上连接器 18和下连接器 28连接的机 体 1和基座 2， 基座 2下设有基座底盖 21 , 所述机体 1内设有上控制电路板 13， 所 述基座 2内设有下控制电路板 23 , 所述机体 1上设置有上发射接收装置 12， 所述 基座 2上设置有下发射接收装置 22， 所述上发射接收装置 12通过导线与上控制电 路板 13相连， 所述下发射接收装置 22通过导线与下控制电路板 23相连， 所述上 发射接收装置 12设置在机体 1的机体底盖 15上， 所述下发射接收装置 22设置在基 座上壳 25上， 所述机体 1和底座 2上设置有光反射结构 14、 24 , 所述上发射接收 装置 12和下发射接收装置 22的发射接收头部分别设置在机体 1和底座 2上的光反 射结构 14、 24中， 当机体 1与基座 2通过上、 下连接器 18、 28连接在一起时， 机 体 1和底座 2上设置的光反射结构 14、 24位置上互相对应。 在本实施例中， 所述 光反射结构由上光反射结构 14和下光反射结构 24组成， 所述机体 1上设置的光反 射结构 14是在机体底盖 15的外表面上设置凹形反射槽 16， 凹形反射槽 16内设置 光反射材料涂层或凹形反射槽 16采用光反射材料制成， 或在机体底盖 15的外表 面设置光反射材料， 一般光反射材料层采用光面的金属材料、 光面的浅色塑料 或采用一些塑料电镀金属膜或铝箔等等， 只要是对光反射效果较好的材料都可 用。 所述机体上设置的上光反射结构 14也可采用在机体底盖 15的外表面上贴上 反光的材料如铝箔、 镀膜薄膜等等材料， 而在基座 2上设置 形反射槽， 设置 凹形反射槽的目的是使上发射接收装置 12或下发射接收装置 22的发射接收头发 出的红外线光反射效率较高， 至于凹形反射槽的深度设置则需要根据材料的不 同来设定。 所述机体底盖 15上设置有透光材料结构或通孔。 所述上发射接收装 置 12的发射接收头部位置与透光材料对应或处于通孔中， 本实施例中在机体底 盖 15上设置透光材料或通孔的目的是保护上发射接收装置 12的红外线发射接收 头部， 将红外线发射接收二极管设置在机体底盖 15的内部， 让红外线发射接收 二极管的头部发出的红外线光和接收红外线光吋能够顺畅通过透光材料， 不受 阻碍， 这样就能使红外线发射接收二极管的头部不易因刮花而影响红外线光的 发射和接收。 当然， 将红外线发射接收二极管设置在机体底盖 15的通孔中， 使 红外线发射接收二极管的头部低于其表面， 也能较好的防止其被刮花。 所述机 体 1和基座 2上的凹形反射槽 16和光反射材料结构是以上连接器 18和下连接器 28 的中心为圆心的圆环形， 所述的凹形反射槽 16的横截面可以制作为半圆弧形或 矩形或有利于光反射的形状结构。
所述的上发射接收装置 12和下发射接收装置 22是采用配对的红外线发射接收二 极管。 即可以采用单个的红外发射接收二极管， 也可采用发射接收二极管封装 在一起的组件。 本实施例中所述的上连接器 18和下连接器 28是 360度旋转式结构 连接器。
[43] 本实施例的工作过程：
[44] 本实施例以"本发明应用于电子电热水壶上， 机体与基座上设有光反射结构" 为例， 如图 1、 图 1-1、 图 1-2、 图 2、 图 3、 图 4所示， 当将机体 1 (电热水壶） 的 壶体装有适量的水后， 放在基座 2 (电源线座） 上后， 这时电源的火线、 零线、 地线通过电连接器的上连接器 18和下连接器 28上相应的触点 （这里未画出） 接 通， 这时， 电热水壶的控制电路接通电源， 当用户需要烧水吋， 按一下基座 2上 的功能按键 29， 基座 2内的控制电路上的微处理器接收到需要烧水的信号， 经过 数据处理后， 给下控制电路发出一个信号， 通过下控制电路板 23上连接的下发 射接收装置 22上的红外线发射二极管， 发出红外线光控制信号， 红外线光控制 信号穿过基座 2的基座上壳 25上的透光片 27， 到达机体底盖 15上设置的凹形反射 槽 16上设置的上光反射结构 14上， 若上发射接收装置 12的红外线接收二极管与 下发射接收装置 22的红外线发射二极管位置上不在一条线上， 或偏离太远， 则 下发射接收装置 22发出的红外线这时不能不经过反射就直接到达上发射接收装 置 12的红外线接收二极管， 这样， 红外线光碰到机体底盖 15上设置的凹形反射 槽 16上设置的上光反射结构 14后返回基座上壳 25， 红外线光碰到基座上壳 25上 设置的下光反射结构 24上又反射回机体底盖 15上设置的凹形反射槽 16上设置的 上光反射结构 14上， 就这样， 红外线光控制信号在机体底盖 15上设置的凹形反 射槽 16的上光反射结构 14与基座上壳 25上设置的下光反射结构 24之间不断地反 复反射， 直到到达上控制电路板 13上的上发射接收装置 12的红外线接收二极管 ， 当上发射接收装置 12的红外线接收二极管接收到下发射接收装置 22的红外线 发射二极管发出的红外线光控制信号后， 控制电路上的微处理器经过数据处理 ， 给控制电路发出一个接通发热体 11的控制信号， 这时， 控制发热体 11的继电 器的触点接通， 发热体 11的接通电源， 发热体 11因接通电源开始加热。
[45] 当机体 1 (电热水壶） 的达到开水温度吋， 机体内的上控制电路的微处理器检 测出温度传感器 （这里未画出） 温度达到开水温度吋， 微处理器经过数据处理 ， 给控制电路发出一个控制信号， 控制上控制电路中接通发热体 11的继电器触 点断开， 这样发热体 11因无电源而停止加热， 若电路设置有开水报警， 并且报 警电路设置在基座 2上的话， 这吋微处理器将发出一个水烧幵的报警鸣叫的控制 信号， 该信号通过上控制电路板 13上的上发射接收装置 12的红外线发射二极管 发出红外线光控制信号， 红外线光控制信号发出后， 到达基座 2的基座上壳 25的 下光反射结构 24上， 若此时下发射接收装置 22的红外线接收二极管与上发射接 收装置 12上的红外线发射二极管位置上不在一条线上， 或偏离太远， 在红外线 光控制信号不能不经过反射直接到达的位置时， 这样， 红外线光碰到基座上壳 2 5上设置的下光反射结构 24后返回机体底盖 15上设置的凹形反射槽 16上设置的上 光反射结构 14上， 红外线光碰到凹形反射槽 16上设置的上光反射结构 14后又返 回基座上壳 25上设置的下光反射结构 24上， 红外线光碰到基座上壳 25上设置的 下光反射结构 24上又反射回机体底盖 15上设置的凹形反射槽 16上设置的上光反 射结构 14上， 就这样， 红外线光控制信号在机体底盖 15上设置的凹形反射槽 16 与基座上壳 25上设置的下光反射结构 24之间不断地反复反射， 直到到达下控制 电路板 23上的下发射接收装置 22的红外线接收二极管， 当下发射接收装置 22的 红外线接收二极管接收到上发射接收装置 12的红外线发射二极管发出的红外线 光控制信号后， 控制电路上的微处理器经过数据处理， 给控制电路发出一个接 通蜂鸣器的控制信号， 这时， 驱动蜂鸣器的三极管导通， 发出鸣叫声报警。
[46] 在本实施例中， 由于釆用的是 360度旋转式电连接器， 设置在机体 1的机体底盖 15和基座 2的基座上壳 25上的上发射接收装置 12和下发射接收装置 22的位置是不 定的， 使用吋， 机体 1放在基座 2上吋是随意的， 也就是说， 不管机体 1的机体底 盖 15和基座 2的基座上壳 25上的上发射接收装置 12和下发射接收装置 22的位置相 对是任何位置， 通过釆用本发明的"无线信号传输装置及传输方法"的结构和方法 ， 都能使红外线光控制信号顺利到达对应的红外线接收二极管上， 进行正常的 控制。
[47] 具体实施例二：
[48] 如图 5、 图 5-1、 图 6所示， 其为本发明中无线信号传输装置和传输方法的另一 个实施例； 该方案包括通过上连接器 18和下连接器 28连接的机体 1和基座 2， 所 述机体 1内设有上控制电路板 131， 所述基座 2内设有下控制电路板 231， 所述机 体 1上设置有上发射接收装置 121， 所述基座 2上设置有下发射接收装置 221， 所 述上发射接收装置 121通过导线与上控制电路板 131相连， 所述下发射接收装置 2 21通过导线与下控制电路板 231相连， 所述

[49] 本实施例的工作过程：
[50] 本实施例以"本发明应用于电子电热水壶上， 机体与基座上设有光反射结构" 为例， 如图 5、 图 5-1、 图 6所示， 当将机体 1 (电热水壶） 的壶体装有适量的水 后， 放在基座 2 (电源线座） 上后， 这时电源的火线、 零线、 地线通过电连接器 的上连接器 18和下连接器 28上相应的触点 （这里未画出） 接通， 这吋， 电热水 壶的控制电路接通电源， 当用户需要烧水吋， 按一下基座 2上的功能按键 29， 基 座 2内的控制电路上的微处理器接收到需要烧水的信号， 经过数据处理后， 给下 控制电路发出一个信号， 通过下控制电路板 231上连接的下发射接收装置 221上 的红外线发射二极管， 发出红外线光控制信号， 红外线光控制信号通过下连接 器 28 (凸形连接器） ， 到达上连接器 18 (凹形连接器） 上设置的上光反射结构 1 41上， 若上连接器 18的上发射接收装置 121的红外线接收二极管与下发射接收装 置 221的红外线发射二极管位置上不在一条线上， 或偏离太远， 则下发射接收装 置 221发出的红外线这吋不能不经过反射就直接到达上发射接收装置 121的红外 线接收二极管， 这样， 红外线光碰到上连接器 18 (凹形连接器） 上设置的上光 反射结构 141上后返回下连接器 28 (凸形连接器） , 红外线光碰到下连接器 28 ( 凸形连接器） 外壁外表面设置的凹形反射槽 26上的下光反射结构 241上又反射回 上连接器 18 ( 形连接器） 上设置的上光反射结构 141上， 就这样， 红外线光控 制信号在上连接器 18 (凹形连接器） 上设置的上光反射结构 141与下连接器 28 ( 凸形连接器） 外壁外表面设置的凹形反射槽 26上的下光反射结构 241之间不断地 反复反射， 直到到达上控制电路板 131上的上发射接收装置 121的红外线接收二 极管， 当上发射接收装置 121的红外线接收二极管接收到下发射接收装置 221的 红外线发射二极管发出的红外线光控制信号后， 控制电路上的微处理器经过数 据处理， 给控制电路发出一个接通发热体 11的控制信号， 这吋， 控制发热体 11 的继电器的触点接通， 发热体 11的接通电源， 发热体 11因接通电源幵始加热。 当机体 1 (电热水壶） 的达到开水温度吋， 机体内的上控制电路的微处理器检 测出温度传感器 （这里未画出） 温度达到开水温度吋， 微处理器经过数据处理 ， 给控制电路发出一个控制信号， 控制上控制电路中接通发热体 11的继电器触 点断开， 这样发热体 11因无电源而停止加热， 若电路设置有开水报警， 并且报 警电路设置在基座 2上的话， 这吋微处理器将发出一个水烧幵的报警鸣叫的控制 信号， 该信号通过上控制电路板 131上的上发射接收装置 121的红外线发射二极 管发出红外线光控制信号， 红外线光控制信号发出后， 到达下连接器 28 (凸形 连接器） 外壁外表面设置的凹形反射槽 26上的下光反射结构 241上， 若此吋下发 射接收装置 221的红外线接收二极管与上发射接收装置 121上的红外线发射二极 管位置上不在一条线上， 或偏离太远， 在红外线光控制信号不能不经过反射直 接到达的位置吋， 这样， 红外线光碰到下连接器 28 (凸形连接器） 外壁外表面 设置的凹形反射槽 26上的下光反射结构 241后返回上连接器 18 (凹形连接器） 上 设置的上光反射结构 141上， 红外线光碰到上连接器 18 (凹形连接器） 上设置的 上光反射结构 141后又返回下连接器 28 (凸形连接器） 外壁外表面设置的凹形反 射槽 26上的下光反射结构 241上， 红外线光碰到下连接器 28 (凸形连接器） 外壁 外表面设置的凹形反射槽 26上的下光反射结构 241上又反射回上连接器 18 (凹形 连接器） 上设置的上光反射结构 141上， 就这样， 红外线光控制信号在上连接器 18 (凹形连接器） 上设置的上光反射结构 141与下连接器 28 (凸形连接器） 外壁 外表面设置的凹形反射槽 26上的下光反射结构 241之间不断地反复反射， 直到到 达下控制电路板 231上的下发射接收装置 221的红外线接收二极管， 当下发射接 收装置 221的红外线接收二极管接收到上发射接收装置 121的红外线发射二极管 发出的红外线光控制信号后， 控制电路上的微处理器经过数据处理， 给控制电 路发出一个接通蜂鸣器的控制信号， 这时， 驱动蜂鸣器的三极管导通， 发出鸣 叫声报警。
[52] 在本实施例中， 由于采用的是 360度旋转式电连接器， 设置在机体 1的上连接器 18 (凹形连接器） 和下连接器 28 (凸形连接器） 外壁上的上发射接收装置 121和 下发射接收装置 221的位置是不定的， 使用者使用吋， 机体 1放在基座 2上吋是随 意的， 也就是说， 不管机体 1的上连接器 18 (H形连接器） 上的上发射接收装置 121和下连接器 28 (凸形连接器） 外壁上的下发射接收装置 221的位置相对是任 何位置， 通过采用本发明的结构和方法， 都能使红外线光控制信号顺利到达对 应的红外线接收二极管上， 进行正常的控制。
[53] 本发明的传输方法是：
[54] (1) 在采用 360度旋转式电连接器的机体和底座上设置光反射材料和结构。
[55] (2) 将上发射接收装置和下发射接收装置的发射接收头部设置在光反射结构 中。
[56] (3) 当机体与基座通过上下连接器连接在一起吋， 机体和底座上设置的光反 射材料和结构位置上对应。
[57] (4) 当机体底盖上的上发射接收装置发出光控制信号吋。
[58] (5) 光控制信号通过机体底盖到达基座上壳的光反射部位或材料上， 经过反 射， 光控制信号又返回到机体底盖的光反射部位或材料上。
[59] (6) 光控制信号在机体底盖和基座上壳的光反射部位或材料上， 经过多次反 复反射， 最后到达基座上壳的下发射接收装置上， 完成控制动作， 这样完成了 控制信号的整个传输过程。
[60] (7) 相反， 当基座上壳的下发射接收装置发出光控制信号吋， 光控制信号通 过基座上壳到达机体底盖的光反射部位或材料上， 经过反射， 光控制信号又返 回到基座上壳的光反射部位或材料上。
[61] (8) 光控制信号在机体底盖和基座上壳的光反射部位或材料上， 经过多次反 复反射， 最后到达机体底盖的上发射接收装置上， 完成控制动作， 这样完成了 控制信号的整个传输过程。
