[0041] 下面结合附图详细描述本发明。
[0042] 如图 1 所示, 所述的电热膜石英管递进式速沸加热器的部件, 按其功能, 可分为三 个部分, 描述如下。 [0043] 其一, 加热部分。
[0044] 如图 1所示, 加热部分的器件由沸水三通(1 ) 、 沸水管(2) 、 连通管(5) 、 冷水 三通(6) 、 电热膜石英发热管 (7) 、 止回阀 (8) 、 迸水口 (13)进水管(14)联合组成。 所述的冷水三通 (6)接通供水总管(图上未予标出) , 冷水三通 (6)接受供水管供水, 饮 水经由止回阖(8)进入进水管(14), 进入进水管 (14)上揍相接止回阀(8)的下端口, 下 连由连通管(5)串接成 S型布局的电热膜石英发热管(7)的下端口, 饮水流入电热膜石英发 热管(7)后, 接受电热膜石英发热管(7) "以火包水"的加热模式, 经过电热膜石英发热管 (7)三级加热, 当饮水经过三级加热流至呈 S型布局的电热膜石英发热管(7)的上端口时, 饮水已处予沸腾的状态, 瞬间沸腾的饮水经沸水管(2)、沸水三通(1)从热水龙头(图上未 予标出.)泻出。
[0045] 其二, 麵部分。
[0046] 如图 1所示, 控制部分的器件由疏流减压阀(3)、 温控器(4) 、 止回阀(8) 、 延 时电路板 ( 11 ) 、 延时开关 ( 15)联合组成。
[0047] 所述的疏流减压樹 (3)的功能在于, 当饮水沸腾而延时电路仍处工作状态的情况下, 电热膜石英发热管(7)递进式加热器所产生的压力可通过疏流减压阀(3)得以释放, 实现 全加热的目的。
[0048] 换言之, 如机器仍处于加热的工况, 而用户取水量又是少于 350ML这样的情况下, 允 许用户关闭开水龙头停止出水。 这是因为开水龙头关闭后, 疏流减压阀(3)即开始动作, 加 热所产生的压力会顶开疏流减压阀(3)中的阀球(203)把高压气、水排回供水管中。疏流减 压阀(3)的存在, 使用户能随心所欲地获取所需的开水量, 大为提高 Γ操作机器的自由度。
[0049] 反之若用户需大量获取开水量之时, 在这一情况下, 用户只需作重复启动延时开关 ( 15)的轻松劳动就 0K了。
[0050] 如图 2所示, 所述的疏流减压阀 (3) 由三通式上阀体(201) 、 阀球座 (2Θ2) 、 阀 球(203) 、 锕弹簧 (204) 、 下阀体(205)组成, 上阀体(201 )与下阀体(205)采用嫘合, 形成阀体腔,上阀体(201 )充当阀球(203)的阏球座 (202), 阀弹簧(204)顶压阀球(203) 在阀球座 (202)上。
[Θ051]所述的疏流减压阀(3) , 并联安装于沸水管(2)与供水管道之间的位置上, 以便把 高压的水气, 引回到供水通道中。 疏流减压阀(3)三通式的上阀体(201 )即沸水三通 (1 ) 的一个端口与沸水管(2)相揍, 三通中的另一端口则与开水龙头相接通; 疏流减压阀(3)的 下端与止回阀(8) 中的三通式的上阀体(301) 即冷水三通(6)相接通, 当饮水沸腾而延时 电路仍处工作状态而要关闭开水龙头的情况下, 经电热膜石英发热管(7)递进式加热器所产 生的高压水气会顶开疏流减压阀(3) 中的阀球 (203)得以释放, 实现安全加热的目的。
[0052] 如图 3所示,所述的止回阀(8)由三通状上阀体 )、阀孔(102)、阀瓣根(103)、 阀瓣膜(104)、下阀体 ( 105)组成; 所述的上阀体 (101)与下阀体(105)嫘合, 形成止回 阀(8〉的阀腔体;所述的阀腔内设置有软性的阀瓣膜 (1Ό4> , 阀瓣膜 ( 104)和阀瓣根(103〉 呈 L状结构,阀瓣膜(104)和阀瓣根(103)系一体制成,阀瓣根(103)埋植于上阀体(101 ) 与下阀体(105)结合部位的预设槽中; 所-述的止回阀(8)串接于进水管(14)中, 具有控制 饮水只进不出的功能; 使饮水在闭路环境下实现加热。
[0053] 所述的温控器(4) 串联于主电路的零线上, 设置在呈 S型串接的电热膜石英发热管 (7〉的沸水出端口处; 所述的温控器(4), 设定其断路温度为] 当电热膜石英发热管 (7)的表面温度超过 1Ό5Ό或发生机器干烧时, 温控器(4)中的双金属片因热膨胀系数不同 而产生分离原理, 会自动切断电路, 保护机器的安全工作。
[0054 如图 4所示, 所述的延时开关(15)和延时电路板(11 ) 的功能及原理是: 机器在待 机状态时饮机是连接着电源的, 220V市电经 Dl- D4整流, R2限压限流, C 3滤波, 得到直流 工作电压。然后经 R4限流, 使 VT1得到基极偏置电流而导通, 单向可控硅 SCR的触发电流被 VT1对地短路 SCR因无皿电流, 主回路处于断开状态, 机器不工作。 当饮机加热时, 按下延 时开关 ( 15)的同时, 电解电容 C 2充电, 同时 VT2得到基极偏置电流而导通, 此时 VT1的基 极偏置电流被 VT2对地短路, VT1因失去基极偏置电流而截止, SCR触发端得到触发电流而导 通,饮机开始工作; 当松开延时开关(15)后, VT2的基极偏置电流又被断开,但此时因有 C 2 上充电电压的存在, 因此仍能通过 R5维持 VT2的基极偏置电流, VT2导通, VT1截止, SCR继 续导通,维持饮机经常工作,当 C 2上充电电压释放完毕, VT2无基极偏置电流而截止时, T21 导通, SCR截止主回路断开停机。
[0055] 所述的延时开关电路的延时电路板 (11 )安装于保护盒(9) 的下方专设的安装凹槽 中, 以尽量避免高温对电路的影响。
[0056] 进一步, 所述的延时开关电路的延时工作时间为 60秒, 这一时段, 饮机能输出的开 水不少于: 350ML。但用户用水时的用量不可能刚好是 350ML的, 当用量小于 350ML时, 用户关 闭开水龙头即可, 因机内设置的疏流减压阀 (3)在关闭开水龙头后会自行启动, 把开水引流 到饮机的供水管中。这样,机器虽是多工作了几秒钟的时间,但却换来饮机的安全运行和用户 的方便使甩。
[0057] 另一种情况, 如来了一批客人或雷用量会大于 350ML之时, 饮机工作 60秒钟后, 会 自动停止, 在这一情况下, 甩户只需再做一次启动延时开关(15)的轻松劳动就 0 了。
[0058] 其三, 保护及安装部分。
[0059] 如图 1 所示, 保护及安装部分的器件包括: 保护盒 (9)、 安装支架 (12)、 排水管 (16) 、 整合螺孔(17) 、 固定螺孔(18) 。
[0060] 如图 1所示, 所述的保护盒(9)的上部设有止回阀(8)及疏流减压阀 (3)的穿出 孔, 以便冷水及热水的输入和输出。
[0061] 如图 1所示, 所述的保护盒(&〉底部外面, 设有线路板 (12〉的安装槽, 延时开关 电路的线路板(12)可容置其中。
[0062] 如图:(所示, 所述的保护盒(9)两侧的上下方还设有保护盒(9)的整合螺孔(17) 及排水管 ( 16) 穿过及电源线接入的预置孔。
[0063] 如图 1所示, 所述的保护盒(9〉的下方, 设有保护盒(9>的固定蟝孔(18〉 以便实 现固定和安装。
[0064] 如图 1所示, 所述的保护盒(9)的内部, 设有电热膜石英管的安装支架〈12) 。
[0065] 如图 1所示, 所述的二条安装支架 ( 12)分设在保护盒(9)中的两侧, 支架上设有 与电热膜石英发热管(7〉对应的半圆形安装槽,当上下二个保护盒(9)组合时,安装支架(12〉 上 二个半圆形 安装槽就形成一个厘, 把电热膜石英发热管(7)箍合于安装支架(12)上。
ΕΘΘ66] 瞬间沸腾、 宽泛控制、应用广谱的电热膜石英管递进式速沸加热器, 还可根据配伍要 求, 设计成可应用于其它水家电的加热部件。
