下面结合附图和实施例对本发明做进一步的说明。
传统上,如图 1所示,用户操作燃气灶的一般方法是用户先按下燃气灶灶台面 (3) 上的调节旋钮 (5) ,开始一个电打火的过程,然后旋转调节旋钮 (5),调节旋钮 (5)带动 旋转轴(17)打开燃气, 于是便点燃了燃气灶的火焰; 在烹饪的过程中, 用户也是顺 时针或逆时针旋转调节旋钮 (5)来调节燃气灶火焰的大小; 烹饪结束后, 用户顺时针 调节旋钮 (5)直到火焰熄灭。 调节旋钮 (5)可旋转的范围是 180 ° 。
需要说明的是本发明的灶台面 (3)包括前面板,前面板是灶台面 (3)的一部分,而 不单独列出前面板。 本发明通过模拟人操作燃气灶的过程实现对火力大小的控制和渐进调节、点火和 熄火等的电动控制。 实施例 1:
实施例 1的特点是下按装置 (10)与外罩 (4 )采取一体式。 图 1到图 7是实施 例 1的示意图。
如图 1所示, 灶台面 (3)上装有基座 (12)和嵌套式渐进火力调节器 (6)。 基座 ( 12) 固定并围绕在一个调节旋钮 (5) 的周围; 如图 4到图 7所示, 嵌套式渐进火 力调节器(6 ) 由外罩 (4)、 主动电机模块(8)、 嵌套式旋钮 (9)和下按装置 (10 )组 成; 基座(12 )和嵌套式渐进火力调节器(6)通过锁扣装置(11 )进行拆卸或固定, 锁扣装置(11 ) 由外罩(4)上的插孔(44)、 基座(12 ) 的插孔(121 )和插栓(12?Λ 组成, 如图 3所示; 当用户想把嵌套式渐进火力调节器 (6)装到燃气灶上时, ^ 把外罩 (4) 的下表面置入基座 (12) 中, 让插孔(44)和插孔(121 )对准, 把插栓 ( 122) 从插孔 (44) 插入即可, 即形成图 1和图 2的样子, 这样就把嵌套式渐进火 力调节器(6) 固定在燃气灶上了; 当用户想把嵌套式渐进火力调节器(6)从燃气灶 上拆下时, 只需把插栓(122)从插孔(44)和插孔(121 )抽出即可, 这样就能方便 地实现用户在手动控制和电动控制调节旋钮 (5)之间进行快速切换, 也不需要对原有 的燃气灶和调节旋钮 (5)进行更多的改造。
现在详细说明一下实施例 1中的嵌套式渐进火力调节器(6),如图 4到图 7所示, 嵌套式渐进火力调节器(6) 由外罩(4)、 主动电机模块(8)、 嵌套式旋钮 (9)和下按 装置 (10) 组成。 其中嵌套式旋钮 (9) 位于外罩 (4) 的内腔 1 (41 ) 中, 调节旋钮 (5)的外围轮廓可以嵌入嵌套式旋钮 (9)中, 主动电机模块(8)位于外罩(4)的内腔 2 (42) 中并可在内腔 2 (42) 中运动; 主动电机模块(8)包括电机(81 )和柱状体
(82), 电机 (81 ) 嵌入并固定于柱状体 (82 ) 的内部, 电机 (81 ) 的旋转轴 (83) 上固定着嵌套式旋钮 (9) ; 下按装置 (10)位于外罩 (4) 的内腔 3 (43) 中, 下按装 置(10) 的滑杆(101)固定在柱状体(82)的上表面; 作为一种优选的方式,下按装置 ( 10)采用电磁铁拉动式, 比方说采用框架式电磁铁。 下按装置(10)采用框架式推 出式电磁铁,由导磁体和滑杆组成,当导磁体通电时,导磁体产生的磁力把滑杆(101) 推出, 使得滑杆(101)向外产生一段行程。
作为一种优选的方式, 电机(81 )采用步进电机, 因为步进电机是纯粹的数字控 制电动机, 步进电机的角度转动与输入脉冲严格成正比, 没有累计误差; 步进电机动 态响应快、 输出转矩大, 在步进电机驱动和控制模块 (752) 的控制下易于起停、 正 反转及变速; 步进电机的歩矩角能达到 Γ 左右, 因此能很好的控制步进电机转动的 角度和精度。 步进电机的原理在此不做过多的阐述。
实施例 1中的嵌套式渐进火力调节器 (6) 工作过程是这样的:
当用户希望电动控制燃气灶的点火时, 首先用户需要把嵌套式渐进火力调节器 (6)装到燃气灶上, 把外罩(4) 的下表面置入基座(12) 中, 让插孔(44)和插孔 ( 121 ) 对准, 把插栓 (122) 从插孔 (44)插入, 这样嵌套式渐进火力调节器 (Γ 就固定了。 此时调节旋钮 (5)的外围轮廓嵌入在嵌入嵌套式旋钮 (9), 嵌套式旋钮 I 能够带动调节旋钮 (5)的旋转; 接着, 下按装置(10 )通电, 把滑杆(101)推出, 使得 滑杆(101)向外产生一段行程, 滑杆(101)产生的压力作用于主动电机模块(8), 主动 电机模块 (8 )在内腔 2 ( 42) 中向下运动, 电机 (81 ) 的旋转轴 (83 ) 又对嵌套式 旋钮 (9)产生向下的压力, 嵌套式旋钮 (9)又对调节旋钮 (5)产生向下的压力, 燃气灶 的打火石开始打火,如此便模拟了人手动调节时对调节旋钮 (5)下按产生打火的动作; 又接着,此时下按装置(10 )依旧保持通电,调节旋钮 (5)处于下按的状态, 电机(81 ) 在主控电路的控制下逆时针旋转, 电机(81 )的旋转轴(83)上带动嵌套式旋钮 (9) 逆 时针旋转, 嵌套式旋钮 (9)又带动调节旋钮 (5) 逆时针旋转, 保持一段时间, 当燃气 灶火焰起来后, 下按装置(10 )断电,滑杆(101)产生的压力消失,调节旋钮 (5)弹起, 燃气灶的打火石便不再打火, 如此便模拟了人手动调节时对调节旋钮 (5)按下去以后 再旋转调节旋钮 (5)到一定角度打火的动作。
当用户希望在燃气灶火焰燃烧的过程中电动控制火焰的大小时, 下按装置 (10) 断电。当用户希望调小火力时,电机(81 )在主控电路的控制下逆时针旋转,电机(81 ) 的旋转轴 (83) 上带动嵌套式旋钮 (9) 逆时针旋转, 嵌套式旋钮 (9)又带动调节旋钮 (5) 逆时针旋转; 当用户希望调大火力时, 电机(81 )在主控电路的控制下顺时针旋 转, 电机 (81 ) 的旋转轴 (83 ) 上带动嵌套式旋钮 (9) 顺时针旋转, 嵌套式旋钮 (9) 又带动调节旋钮 (5) 顺时针旋转。这样分别模拟人手动调节时逆时针或顺时针旋转调 节旋钮 (5)来调小或调大火力的动作。
当用户希望在燃气灶火焰燃烧的过程中关闭燃气灶时, 下按装置(10)依然处于 断电状态, 电机(81 )在主控电路的控制下顺时针旋转直至到熄火点的位置。这样分 别模拟人手动调节时或顺时针旋转调节旋钮 (5) 直至到熄火点的位置。
当然下按装置 (10 )还可以采用电机拉动式, 滑杆(101)为一带锯齿的杆, 电机 的旋转轴上装有齿轮, 齿轮与滑杆(101)的锯齿咬合, 当电机的旋转轴旋转时, 依靠 齿轮与滑杆(101)的锯齿的咬合力, 向下或向上推动滑杆(101)。这也是比较成熟的技 术, 不再详述, 也不再用附图描述。
出于成本的考虑, 电机(81 )还可采用慢速电机, 比方说 1分钟 1转的慢速电^ 只要控制好电机的旋转的准确时间,也可以很好的控制慢速电机旋转的角度。这里 再详述。
下面详述一下本发明的电路框图, 如图 13所示。
控制盒 (7 ) 内有控制电脑板 (75)。 控制盒 (7 ) 的示意图如图 12所示。 温度传 感器 (2)、 下按装置(10)、 电机 (81)通过控制线 ( 74 )连接到一个控制盒 (7)内的上控 制电脑板 (75)。控制电脑板 (75)由中央控制处理器(751 )、步进电机驱动和控制模块 ( 752)、温度信号处理模块(753)、键盘处理单元(754)、 LCD显示控制单元(755)、 手机 Modem通信模块(756)、时钟模块(757)、电源模块(758)、电磁铁控制模块(759)、 可燃气体传感器(7510)、 可燃气体浓度处理单元(7511 )、 无线收发单元(7512 )和 嵌入式电话调制解调器 ( 7513 )组成;控制盒 (7)的外壳 (71)上的电源插座(70)、LCD (72) 和键盘 (73 ) 也连接到控制电脑板(75)。
手机 Modem通信模块 (756 )可以远程无线接收来自用户手机上发来的指令, 使 得用户远程无线控制燃气灶的点火、火力大小控制、熄火等过程; 嵌入式电话调制解 调器单元 (7513 ) 可以接到家里的电话线上, 可以通过 PSTN固话网络远程接收用户 通过发来的指令, 使得用户远程通过固话网络控制燃气灶的点火、火力大小控制、熄 火等过程。 燃气灶也可以通过手机 Modem通信模块 (756 ) 或嵌入式电话调制解调器 ( 7513 )发送报警等信息给远方的用户手机上。无线收发单元(7512 )采用红外等接 收器件, 使得用户在家里可以用遥控器控制燃气灶。
本发明采用时钟模块 (757 )给整个电路提供时间信息, 比方说年月日时分秒等 信息,用户可以定时在某一个时间点开始一个燃气灶的蒸煮过程或让燃气灶蒸煮一段 确定长度的时间。
本发明在燃气灶火焰的附近装有温度传感器 (2), 温度传感器 (2) 和温度信号处 理模块 (753 ) 是为了测量燃气灶火焰的温度, 一旦燃气灶的火焰由于某种原因异常 熄灭,比方说蒸煮过程中汤的溢出熄灭了燃气灶火焰, 就有必要进行熄火保护。 因为 火焰的温度比较高,达几百度以上,温度传感器 (2)采用高温传感器,比方说采用铂电 阻温度传感器等, 温度传感器 (2)通过测量火焰的温度知道火焰是否是熄灭了还是正 常燃烧状态。一旦温度传感器 (2)感知到燃气灶的火焰异常熄灭,将控制关闭掉燃 ^ 或者再进行一个电打火重新点燃的过程。 可燃气体传感器(7510 )和可燃气体浓度处理单元(7511 )是用于探测家中厨房 空气中一氧化碳和煤气等可燃气体探测, 防止人不在燃气灶旁边蒸煮东西时,燃气泄 漏造成危险。一旦检测到空气中的可燃气体浓度达到一定浓度,将立即控制控制旋转 关闭掉燃气,防止危险。
LCD (72) 、 键盘 (73)、 键盘处理单元(754) 和 LCD显示控制单元 (755) 形成 人机交互单元, 用户可以设定日期, 设定蒸煮开始的时间和结束的时间, 设定火力的 大小。 实施例 2:
实施例 2的特点是下按装置 (10) 与外罩 (4)釆取分离式, 下按装置 (10 ) 处 于灶体(1)的内部或灶台面 (3)上。 图 8到图 11是实施例 2的示意图。
与实施例 1不同的是, 实施例 2中下按装置 (10 ) 不是处于外罩 (4) 的内部, 而是处于灶体(1)的内部, 如图 8所示, 旋转轴 (17 ) 的一端与下按装置 (10) 的滑 杆(101)连在一起。 作为一种优选的方式,下按装置(10 )采用电磁铁拉动式, 比方说 采用框架式电磁铁。下按装置(10 )采用框架式吸入式电磁铁, 由导磁体和滑杆组成, 当导磁体通电时,导磁体产生的磁力把滑杆(101)拉进,使得滑杆(101)向里产生一段 行程, 从而对旋转轴 (17 ) 产生下拉的动作, 起到一个燃气灶打火的动作。
与实施例 1一样, 当然下按装置 (10)还可以采用电机拉动式, 下按装置 (10) 还有不同的实现方式和变形, 可以以直接或间接的方式拉动旋转轴 (17), 这些不再 列举。
与实施例 1还有不同的是, 还有实施例 2中的嵌套式渐进火力调节器(6), 如图 9到图 11所示, 嵌套式渐进火力调节器(6 ) 只由外罩 (4)、 主动电机模块 (8)、 嵌 套式旋钮 (9)组成。 其中嵌套式旋钮 (9) 位于外罩 (4) 的内腔 1 (41 ) 中, 调节旋钮 (5)的外围轮廓可以嵌入嵌套式旋钮 (9)中, 主动电机模块(8 )位于外罩(4)的内腔 2 (42) 中并不能在内腔 2 (42) 中运动; 主动电机模块 (8)包括电机 (81 )和柱状 体(82), 电机(81 )嵌入并固定于柱状体(82 ) 的内部, 电机(81 ) 的旋转轴 (83) 上固定着嵌套式旋钮 (9)。
其他的结构特点与实施例 1都有相同的结构, 不再重述。 实施例 2中的嵌套式渐进火力调节器 (6 ) 工作过程是这样的: 当用户希望电动控制燃气灶的点火时, 首先用户需要把嵌套式渐进火力调节器 (6 )装到燃气灶上, 把外罩(4) 的下表面置入基座(12) 中, 让插孔(44)和插孔 ( 121 ) 对准, 把插栓 (122) 从插孔 (44)插入, 这样嵌套式渐进火力调节器 (6) 就固定了。 此时调节旋钮 (5)的外围轮廓嵌入在嵌入嵌套式旋钮 (9), 嵌套式旋钮 (9) 能够带动调节旋钮 (5)的旋转; 接着, 下按装置(10 )通电, 把滑杆(101)拉进, 使得 滑杆(101)向里产生一段行程, 滑杆(101)产生的压力作用于旋转轴 (17), 燃气灶的 打火石开始打火, 如此便模拟了人手动调节时对调节旋钮 (5)下按产生打火的动作; 又接着,此时下按装置(10 )依旧保持通电,旋转轴(17 )处于下按的状态, 电机(81 ) 在主控电路的控制下逆时针旋转, 电机(81 )的旋转轴(83)上带动嵌套式旋钮 (9) 逆 时针旋转, 嵌套式旋钮 (9)又带动调节旋钮 (5) 逆时针旋转, 保持一段时间, 当燃气 灶火焰起来后,下按装置(10)断电,滑杆 (101)产生的的向里拉力消失,旋转轴(17) 弹起, 燃气灶的打火石便不再打火, 如此便模拟了人手动调节时对调节旋钮 (5)按下 去以后再旋转调节旋钮 (5)到一定角度打火的动作。
当用户希望在燃气灶火焰燃烧的过程中电动控制火焰的大小时, 下按装置 (10) 断电。当用户希望调小火力时,电机(81 )在主控电路的控制下逆时针旋转,电机(81 ) 的旋转轴 (83) 上带动嵌套式旋钮 (9) 逆时针旋转, 嵌套式旋钮 (9)又带动调节旋钮 (5) 逆时针旋转; 当用户希望调大火力时, 电机(81 )在主控电路的控制下顺时针旋 转, 电机 (81 ) 的旋转轴 (83 ) 上带动嵌套式旋钮 (9) 顺时针旋转, 嵌套式旋钮 (9) 又带动调节旋钮 (5) 顺时针旋转。这样分别模拟人手动调节时逆时针或顺时针旋转调 节旋钮 (5)来调小或调大火力的动作。
当用户希望在燃气灶火焰燃烧的过程中关闭燃气灶时, 下按装置(10)依然处于 断电状态, 电机(81 )在主控电路的控制下顺时针旋转直至到熄火点的位置。这样分 别模拟人手动调节时或顺时针旋转调节旋钮 (5) 直至到熄火点的位置。
在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化 和改进都落入要求保护的本发明范围内。本发明要求保护的范围由所付的权利要求 及其等效物界定。
