一种触摸电壁炉 技术领域
本发明涉及电壁炉领域技术，尤其是指一种触摸电壁炉。

壁炉是一种文化象征，它意味着人拥有一个温馨的家，它敞开温暖，可以让人放松和避难，可以让人享受浪漫的爱。在壁炉前，人们像一位漫步的绅士，或思想活跃、或思绪万千，它能开启人们的思想宝库。在西方，壁炉常是外交或私下谈判的地方，也是人们友好交往、情感交流的场合，有时也是家庭的核心区域。总之，壁炉是一种感情的象征，关系着爱、温暖、友谊，它已超越了简单的实用功能而呈现出特有的文化功能。
由于空间的限制，目前壁炉大多出现在别墅、复式等有足够空间容纳它的地方。在风格上，壁炉也需要一定的搭配和协调，因为壁炉在欧式风格的装修中很普遍，从某种意义上说，壁炉已经成为了欧式古典设计的一个标志。壁炉的原有作用是取暖，但在中国现代家居设计中，壁炉更多的作用是装饰。现在流行的新式壁炉构思巧妙、造型时尚、创意丰富、工艺简约，与新古典风格的搭配非常统一。
随着时代的发展，电壁炉基本上取代了传统的壁炉，然而，现有技术的电壁炉的操作模式大多是用机械开关或轻触按键进行控制，产品寿命短，观赏性差，不能与整块平面玻璃或弧形玻璃完美结合，以使市场上现有的电壁炉都不能在玻璃或绝缘板这一类材料的表面进行触摸控制操作，而且传统电壁炉的轻触按键或机械开关都需在前机壳开孔后才能安装，增加生产加工的难度，给产品全新设计和创新带来不便，导致电壁炉行业难以获得突破发展，无法满足人们追求高质量生活的需求。除此之外，传统电壁炉受制于其轻触按键或机械开关都需在前机壳开孔位置，无法把前透明绝缘板做成整块平面或整块弧形效果，使电壁炉透光窗口上的前盖板大同小异，千篇一律，没有任何新意，难以吸引消费者的眼球和引起消费者的购买兴趣。

首先，请参照图1至图4所示，其显示出了本发明之较佳实施例的具体结构，其包括壳体7、成像屏3、木炭光源12、成像光源9、火焰处理装置13、反光处理装置2、透明绝缘板8、触控单元6及主控板5。
参照图1，所述壳体7为可以依据实际需要制成各种古典式或时尚的结构，在本实施例中，该壳体为一大概呈长方体状的箱子，该触摸电壁炉的各个结成部件均安装在壳体7内。具体而言，所述壳体前壁开设有一透光窗口，所述透明绝缘板8可以制作为整块平面形状或具有拱起的弧形效果，其完全遮盖住壳体7边沿，为了增加美感，于该透明绝缘板8的四周印刷有不同颜色花纹的图案层。所述透明绝缘板8安装在壳体7的前壁面的透光窗口上，其与壳体7的边沿吻合紧贴，该透明绝缘板8背面的壳体7底面上设有一支承架，该支承架上放置有使电壁炉显得非常真实的仿真木炭1，前述成像屏3板面竖直地安装在支承架上，其位于仿真木炭1的后方；所述火焰处理装置13安装在成像屏3的后方，火焰处理装置2的底部与成像屏3的底部相贴，顶部与成像屏3保持有间距。所述反光处理装置2是一电机带动可转动的反光组件，其安装在火焰处理装置13的背面的底部，而木炭光源12安装在支承架下方的壳体7底面上，其光线射入到仿真木炭1中，使仿真木炭1具有燃烧的感觉。于反光处理装置2下方设有成像光源9，其光线射到成像屏3上。所述主控板5嵌入在壳体7中固定在成像屏3的上方。
如图2和图3所示，该透明绝缘板8的表面复合有触摸感应面板4，该触摸感应面板4与主控板5电性连接，且触摸感应面板4与透明绝缘板8之间复合有印刷层11，该触摸感应面板4通过印刷层11可以任意印刷在透明绝缘板8的四周。除此之外，该触摸感应面板4还包括文字标志层10和LED灯透光窗口；所述LED灯透光窗口为一无开孔、无被印刷层覆盖的透明窗口，该文字标志层10印刷在LED灯透光窗口的边缘，所述文字标志层10具体是指ON/OFF、DIMMER、LOW、HIGH等指示文字。
所述触摸感应面板4背面设有触控单元6，该触控单元6包括分别与主控板5连接的感应导电电极、触摸控制芯片、LED指示灯和红外接收器，感应导电电极安装在LED透光窗的背面，LED指示灯位于感应导电电极的中心位置。在本实施例中，所述LED指示灯有四个，感应导电电极也有四个。
工作过程中，当人对触摸感应面板4进行触摸控制时，触控单元6输出信号传送到主控板5，控制成像光源9发出暖白色光线，光线通过反光处理装置2反射到火焰处理装置13进行火焰整形，再反射到成像屏3，形成火焰图样，这样，在透明绝缘板8前面就可以看到非常逼真的火焰。
如图4所示，所述的触控单元6的电路模块包括触摸感应芯片20、触摸感应输入电路16、LED灯指示电路17、电源滤波电路22、第一连接器26、第二连接器27、主控MCU21和信号接收电路15。该触摸感应芯片20和主控MCU21的电源端分别与电源滤波电路22连接，该第一连接器26、第二连接器27分别与触摸感应芯片20及主控MCU21的信号传输端口连接，触摸感应芯片20的输出信号端连接到主控MCU21上, 输入控制端与触摸感应输入电路16连接,信号接收电路15和LED指示电路17分别连接到第一连接器26上。
各个电路模块的具体结成元件及各元件之间的电路连接结构详述如下：
所述触摸感应输入电路16包括四个感应导电电极K、输入电阻R5、R6、R7、R8，各感应导电电极K的一端分别与输入电阻R5、R6、R7、R8一端连接，输入电阻R5、R6、R7、R8的另一端与触摸感应芯片20的输入端连接，由触摸感应芯片20把输入信号进行内部采样及处理，再把输出信号通过第一连接器26和第二连接器27传输到主控MCU21。本实施例中，感应导电电极K采用导电弹簧。
所述LED灯指示电路17包括LED灯L1、L2、L3、L4和限流电阻R1、R2、R3、R4；该LED灯L1、L2、L3、L4的一端与限流电阻R1、R2、R3、R4的一端连接，限流电阻R1、R2、R3、R4的另一端与第一连接器26对应的输出信号连接，从主控MCU21输出驱动信号到第二连接器27，再由第二连接器27与第一连接器26对应连接，该LED灯L1、L2、L3、L4的另一端与电源接地端连接，形成接地回路。所述LED灯L1、L2、L3、L4的发光颜色可以是红色、黄色、绿色、蓝色等，本实施例中，LED指示灯发光颜色采用红色。所述LED灯L1、L2、L3、L4的封装方式可以为插件方式或贴片式封装，这些LED灯对应放置于触摸感应面板4之感应键的中心位置。
所述电源滤波电路22包括电解电容C1和瓷片电容C2，电解电容C1和瓷片电容C2的一端连接于电源正极VDD，电解电容C1和瓷片电容C2的另一端连接于电源接地端，该电源滤波电路22可以增强触摸感应芯片20和主控MCU21的电源纹波抗干扰能力，而且触摸感应芯片20和主控MCU21共用一个电源，共用一个接地端。
所述信号接收电路15包括红外接收器REC，限流电阻R9，电解电容C3和瓷片电容C4；该电解电容C3与限流电阻R9的一端与红外接收器REC的电源端连接，该限流电阻R9的另一端与电源正极VDD相连接，瓷片电容C4、电解电容C3的另一端相连接后与红外接收器REC的接地端连接在一起，形成共用接地。红外接收器REC的信号端与瓷片电容C4一端连接，接收信号传输到连接器26的对应端口上，再与连接器27对接后，传送到主控MCU21的信号输入端口上，进行信号解码与指令实施。该红外接收器REC可以装装在触摸感应面板4上，也可以引线外拉到壳体7的中间位置或成像屏3的背后位置进行安装，本实施例中，红外接收器REC采用外拉引线方式，方便安装。
该触摸电壁炉的电路原理为：当手指接触到触摸感应电路16的感应导电电极K时，感应导电电极K与手指间形成电容脉冲信号，输入到触摸感应芯片20内部，经触摸感应芯片20内部处理后，输出相应的电压变化到主控MCU21进行控制指令实施，同时输出信号控制LED灯指示电路17，实现将手指触摸信号感应识别为按键信息，而对电壁炉操作控制。触摸感应芯片20和主控MCU21的电源经电源滤波电路22处理后提供，用第一连接器26、第二连接器27把触摸感应芯片20和主控MCU21的信号传输连接在一起。触摸感应芯片20控制多路信号切换到主控MCU21进行信号处理，触摸感应信号切换是受触摸感应芯片20控制，指令信号实施是受主控MCU21控制。
综上所述，本发明的设计重点在于：
一、通过在电壁炉上设置触摸感应面板、触控单元和主控板，从而只需要在触摸感应面板上轻轻点按，即可实现对电壁炉的控制功能，产品不但美观时尚，而且耐用性好、使用操作更为方便。
二、通过将壳体前端的透明绝缘板制作成整块平面或整块弧形凸起，其完全覆盖住显示窗口及其边沿，配合触摸技术，使整块透明绝缘板与壳体完美结合，有效增加产品的美感和新意，更容易吸引消费者的眼球和引起消费者的购买兴趣。
三、通过在透明绝缘板的按键区域复合触摸感应面板、触控单元和主控板，无需在壳体边沿及透明绝缘板边沿开孔安装机械开关或轻触按键，简化按键区的制作工艺，避免传统电壁炉开孔安装带来的麻烦，增加透明绝缘板安装的方便性。
四、通过将触摸感应面板及触控单元设计在透明绝缘板的两面，使手指的触摸区与电路连接区完全隔离开，从而产品具有防水性能，手指触摸沾水也不会出现触电或短路现象，操作安全可靠、使用寿命长。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
