本发明涉及一种燃气灶具, 尤其是一种模拟人操纵燃气灶过程的燃气灶具。 背景技术
用户在用燃气灶进行烹饪的过程中, 需要打开或关闭火力或者调节火力大小。烹 饪开始时, 用户首先按下燃气灶前面板上的调节旋钮,进行一个电打火的过程, 然后 再逆时针旋转调节旋钮, 点燃燃气灶的燃气,在烹饪的过程中根据需要逆时针或顺时 针地旋转调节旋钮来调节燃气灶的火力大小。烹饪结束时,用户再顺时针地旋转调节 旋钮关闭燃气灶的火焰。 调节旋钮的可调范围是 180度,但是火力从最大到最小调节 旋钮的可调范围是 90度。 用户有时自己用手调节燃气灶的火力大小时, 由于手法或 轻或重, 火力大小的调节不易掌握。
已有的关于燃气灶火力大小调节的专利中, 需要加入燃气电磁阀造成成本过高, 要么结构复杂需要做过多改造。还有现在的人们希望能远程控制燃气灶,如人们希望 在下班回家之前就能远程点燃燃气灶开始某一种烹饪过程,能远程控制燃气灶的火力 大小, 能远程控制熄灭燃气灶的火焰。而且这些专利中, 没有考虑进自动进行燃气灶 点火这样一个过程,因为点火也是一种火力控制的过程。

具体实施方式
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前面板 (5) 上的调节旋钮 (6) ,开始一个电打火的过程,然后旋转调节旋钮 (6),调节旋钮 (6)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
5
更正页 (细则第 91条) 时针或逆时针旋转调节旋钮 (6)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 (6)直到火焰熄灭。 调节旋钮 (6)可旋转的范围是 180° 。
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中, 主动旋钮 (8)以履带传动式带动从动旋钮 (9)旋转,并且旋转轴电控 按下装置采用电磁铁带动式, 电磁铁(12)通电时以间接带动式按下旋转轴 (17 )。 图 1到图 15是从各个方向观看实施例 1时的视图和立体分解图。
燃气灶的前面板 (5)上固定有步进电机 (15) , 步进电机 (15)通过螺丝等方式固定 在前面板 (5)上; 步进电机(15)隐藏于前面板 (5)后面的灶体中 (1 ), 可以从图 2、 图 7、 图 8、 图 9、 图 10看到步进电机(15)的样子。
采用步进电机 (15)是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; 步进电机的步矩 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。
如图 2、 图 3、 图 4、 图 5、 图 6所示,步进电机(15)的转轴 (16) 上装有主动旋 钮 (8) , 转轴 (16) 能带动主动旋钮 (8)旋转, 旋转轴(17)上装有一种新型的从动旋 钮 (9) ,从动旋钮 (9 ) 带动旋转轴 (17)旋转; 主动旋钮 (8)的横梁 (82 ) 固定着上履 带(10 ) —端, 从动旋钮 (9)的横梁(92 ) 固定着上履带 (10 ) 的另一端,这样主动旋 钮 (8)通过拉动上履带(10)进而带动从动旋钮(9 )逆时针方向旋转, 从动旋钮(9 ) 再带动旋转轴 (17) 逆时针方向旋转,调节燃气火力的大小, 这样就模拟了人用手逆 时针旋转调节旋钮(6)的过程; 主动旋钮 (8)的横梁(82)固定着下履带(11 )一端, 从动旋钮 (9)的横梁 (92) 固定着下履带 (11 ) 的另一端,这样主动旋钮 (8)通过拉动 下履带(11 )进而带动从动旋钮(9 )顺时针方向旋转, 从动旋钮(9 )再带动旋转轴 ( 17 ) 顺时针方向旋转,调节燃气火力的大小, 这样就模拟了传统上人用手顺时针旋 转调节旋钮(6)的过程; 主动旋钮 (8)开有一个凹形的绕线槽 (81), 从动旋钮 (9) 也
6
更正页 (细则第 91条) 幵有一个凹形的绕线槽 (91),这样是为了使得上履带 (10) 和下履带 (11 ) 都沿着绕 线槽 (81)和绕线槽 (91)内运动而不会滑出。本发明中采用步进电机可以很好地多级调 节调节燃气火力的大小,具有很好的可控性和精度, 解决人手调节火力的不精确性。
燃气灶的前面板 (5)上固定有电磁铁 (12)、 连接片(13)和固定柱(14) , 如图 2、 图 8、图 9、图 10所示。作为一种优选的方式, 电磁铁(12)采用框架式吸入式电磁铁, 电磁铁(12)由导磁体(121)和滑杆(122)组成, 如图 9所示, 当导磁体(121)通电时, 导磁体 (121)产生的磁力把滑杆(122)吸入, 使得滑杆(122)向里产生一段行程; 导磁 体(121) 隐藏于前面板 (5)后面的灶体中 (1 ) 中, 固定在前面板 (5)上; 滑杆(122) 一端通过嵌在有连接片(13)的中间的孔二 (132 ) , 如图 8、 图 9、 图 10所示; 连接 片(13)的孔一 ( 131 ) 套在旋转轴 ( 17 ) 上,如图 14所示; 连接片(13)的孔三 ( 133 ) 套在固定柱(14)的滑动槽(141),如图 9、图 10所示, 孔三(133)可沿着滑动槽(141) 滑动; 固定柱(14)也固定前面板 (5)上。 这样, 如图 2至图 6所示,导磁体(121)通电 时吸入滑杆(122) , 滑杆(122)带动连接片(13)运动, 连接片(13)再对旋转轴(17)产 生向下的压力, 从而按下旋转轴 (17 )。 传统上,人用手按下调节旋钮 (6) , 调节旋 钮(6)再按下旋转轴(17 )进行电打火的过程。这样通过连接片(13)按下旋转轴(17 ) 就模拟了人操纵电打火的过程。当电磁铁(12)断电或者加一个反向电压时,滑杆(122) 不再被吸入, 而且由于灶体 (1 ) 内部结构对旋转轴 (17) 有一个向外的反弹力, 旋 转轴(17) 因此从按下转为弹起, 这样就模拟了传统上人松幵调节旋钮(6) 的过程。 电磁铁控制模块 (759 ) 对电磁铁(12)进行驱动和控制, 对电磁铁(12)施加不同方向 的电压或断电。
温度传感器 (4)、 电磁铁(12) 、 步进电机(15)和电机(18)通过控制线(74 )连接 到一个控制盒 (7)内的控制电脑板 (75)上,如图 7、 图 8、 图 9和图 36所示。本发明的 电路框图如图 37所示, 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
更正页 (细则第 91条) 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 (4), 如图 1、 图 7、 图 11所示。 温 度传感器 (4) 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 (4)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 (4)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 (4)感知到燃气灶的火焰 异常熄灭, 将控制主动旋钮 (8)带动从动旋钮 (9 ) 旋转关闭掉燃气,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 露造成危险。一旦检测到空气中的可燃气体浓度达到一定浓度,将立即控制控制主动 旋钮 (8)带动从动旋钮 (9 ) 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。
作为主动旋钮带动从动旋钮的示意, 图 1 1是主动旋钮带动从动旋钮旋转 90度。

更正页 (细则第 91条) 图 12是主动旋钮带动从动旋钮旋转 135度。 图 13是主动旋钮带动从动旋钮旋转 180 度。 本发明可以以 Γ 左右的精度实现主动旋钮带动从动旋钮的渐进调节。
如图 14和图 15所示, 主动旋钮 (8)、从动旋钮 (9)、上履带(10)和下履带(11 ) 能一起从转轴 (16) 和旋转轴 (17 ) 随时拿开和装上, 换上普通的调节旋钮 (6 ) , 换上普通的调节旋钮(6), 用户就可以用调节旋钮(6)手工调节, 根据需要在电动 调节和手动调节火力之间随时切换。 实施例 2:
实施例 2中, 主动旋钮 (8)以齿轮传动式带动从动旋钮 (9)旋转,并且旋转轴电控 按下装置采用电磁铁带动式, 电磁铁(12)通电时以间接带动式按下旋转轴 (17 )。 图 16到图 22是从各个方向观看实施例 2时的视图和立体分解图。
实施例 2的燃气灶的内部结构, 如步进电机(15)、 电磁铁(12)、 固定柱(14)都与 实施例 1一样, 如图 2所示透视图的燃气灶的内部结构,这几个部件的描述请参照实 施例 1的描述。
旋转轴电控按下装置采用电磁铁带动式,电磁铁(12)通电时以间接带动式按下旋 转轴 (17 ) 的方式和结构也与实施例 1一样。 电磁铁(12)采用框架式吸入式电磁铁, 电磁铁(12)由导磁体(121)和滑杆(122)组成, 如图 18所示, 当导磁体(121)通电时, 导磁体(121)产生的磁力把滑杆(122)吸入,使得滑杆(122)向里产生一段行程,再带动 连接片(13)按下旋转轴 (17)。
与实施例 1不一样的是: 主动旋钮 (8)的外围是齿轮(83), 从动旋钮 (9) 的外围 是齿轮 (93 ), 主动旋钮 (8)以齿轮传动式带动从动旋钮 (9)旋转,主动旋钮 (8)的齿轮 (83) 与从动旋钮 (9) 的齿轮 (93 ) 咬合。 如图 18、 图 19所示, 步进电机(15)的转 轴(16 )旋转时带动主动旋钮 (8)旋转,主动旋钮 (8)的齿轮(83)通过从动旋钮 (9) 的 齿轮(93)带动从动旋钮 (9)同一方向旋转, 从动旋钮(9)再带动旋转轴(17 )旋转, 从而调节燃气火力的大小。
从动旋钮 (9)能随时从旋转轴 (17 ) 上拿开和装上, 换上普通的调节旋钮 (6 ) , 如图 20、 图 21、 图 22所示。 这样主动旋钮 (8)的齿轮 (83) 没有任何的接触, 用户
9
更正页 (细则第 91条) 就可以用调节旋钮 (6) 手工调节, 根据需要在电动调节和手动调节火力之间随时切 换。 如图 21所示, 从动旋钮 (9)的固定孔 (94) 与调节旋钮 (6) 的固定孔 (61 ) 有 相同的形状, 能嵌套和固定在旋转轴 (17) 上, 从动旋钮 (9)也能从旋转轴 (17) 上 拿开。

实施例 3与实施例 2几乎一样,与实施例 2不同的点是:实施例 3的从动旋钮 (9) 的齿轮 (93 ) 具有更多的齿数, 从而主动旋钮 (8)旋转时能以更小的角度分辨率带动 从动旋钮 (9)旋转; 另外, 主动旋钮 (8)能随时从旋转轴 (17 ) 上拿开和装上, 如图 26 所示, 当主动旋钮 (8)拿幵后, 用户就可以用从动旋钮 (9)手工调节, 根据需要在 电动调节和手动调节火力之间随时切换。

实施例 5中, 主动旋钮 (8)以履带传动式带动从动旋钮 (9)旋转,并且旋转轴电控 按下装置采用电机带动式,图 30到图 35是从各个方向观看实施例 5时的视图和立体 分解图。
实施例 5的燃气灶的步进电机 (15)、连接片(13) 、 固定柱(14) 、 主动旋钮 (8)、 从动旋钮 (9)、 上履带 (10)、 下履带 (11 ) 都与实施例 1一样有同样的结构和方式。 这几个部分描述请参照实施例 1和图 30、 图 31、 图 32所示。
实施例 5与实施例 1不一样的是: 实施例 5旋转轴电控按下装置不采用电磁铁带 动, 而采用电机带动式, 在灶体(1)内部固定有电机(18),电机(18)的旋转轴(19 ) 固 定着钢索 (20) 的一端, 钢索 (20) 的另一端通过导向轮 (21 ) 连接到滑杆(122)的 另一端底部, 如图 32至图 35所示。此处电机(18)可以采用步进电机, 但由于步进电 机的成本相对普通电机较高, 也可以采用转速很慢的普通电机, 比如 2转 /每分钟的 的慢速电机。电机 (18)的旋转轴(19 )旋转时,使得钢索(20)—端缠绕在旋转轴(19 ) 上, 钢索 (20 ) 的另一端通过导向轮 (21 ) 对滑杆(122)产生一种拉力, 滑杆(122) 带动连接片(13)运动, 连接片(13)再对旋转轴(17 )产生向下的压力, 从而按下旋转 轴 (17), 产生一个打火的动作; 电机(18)的旋转轴 (19 ) 反方向旋转时, 钢索 (20) 不再缠绕在旋转轴 (19 ) 上, 钢索 (20) 的另一端通过导向轮 (21 ) 对滑杆(122)产 生的拉力消失, 旋转轴 (17 ) 自然弹起, 结束打火的动作。
