技术领域technical field

本发明涉及一种空调器，特别涉及一种面板带有装饰光源的壁挂式空调室内机。The invention relates to an air conditioner, in particular to a wall-mounted air conditioner indoor unit with a decorative light source on the panel.

背景技术Background technique

现代生活中，空调器已经成为人们不可或缺的电器之一，在办公室、家居房间里作为空气温度、湿度调节的装置扮演重要角色。通常，空调包括室内机和室外机，室内机又公为立式、壁挂式和吸顶式的，对于壁挂式空调的室内机，在室内机内的主要部件是室内换热器和室内风机，放置在室内机外壳内。传统上，室外机的外壳前面板只具有功能性的设计而不作任何装饰，使得室内机的外观比较简单，前面板只起到单纯的罩壳功能。随着空调技术的发展以及对室内装饰的要求，有些厂家对室内机的前面板进行精心的设计，例如在前机板上设计装饰图案或者是将前面板设计成装饰面板的整体效果；也有的空调室内机上安装有液晶显示屏甚至在面板上设有广告灯箱。但是，室内机前面板上一成不变的图案使用时间长了难免生厌；应用在空调面板上的液晶显示屏则尺寸较小，不具备豪华气流的效果；在室内机上设广告灯箱则限于灯箱的厚度大难于普及，而且广告灯箱能耗大、光线强烈、不柔和，不能满足人们对舒适家居环境的追求以及高贵气派的审美要求。In modern life, air conditioners have become one of the indispensable electrical appliances for people, and play an important role as a device for air temperature and humidity regulation in offices and home rooms. Usually, an air conditioner includes an indoor unit and an outdoor unit. The indoor units are vertical, wall-mounted and ceiling-mounted. For the indoor unit of a wall-mounted air conditioner, the main components in the indoor unit are the indoor heat exchanger and the indoor fan. Place it inside the casing of the indoor unit. Traditionally, the front panel of the shell of the outdoor unit only has a functional design without any decoration, so that the appearance of the indoor unit is relatively simple, and the front panel only functions as a simple cover. With the development of air-conditioning technology and the requirements for interior decoration, some manufacturers carefully design the front panel of the indoor unit, such as designing decorative patterns on the front panel or designing the front panel as a decorative panel; The air-conditioning indoor unit is equipped with a liquid crystal display and even an advertising light box is arranged on the panel. However, the unchanging pattern on the front panel of the indoor unit is unavoidably tiresome after being used for a long time; the LCD screen used on the air conditioner panel is small in size and does not have the effect of luxurious air flow; the advertising light box on the indoor unit is limited to the thickness of the light box It is very difficult to popularize, and the advertising light box has high energy consumption, strong light, and not soft, which cannot meet people's pursuit of a comfortable home environment and the aesthetic requirements of noble style.

具体实施方式Detailed ways

本发明的壁挂式空调室内机包括贯流风机、室内换热器、控制器与外壳罩，如图1、2所示，外壳罩的面板结构由前面板5、装饰条2、导光板1及光源组成，导光板1固定在前面板5上，在导光板1的下方是装饰条2，The wall-mounted air-conditioning indoor unit of the present invention includes a cross-flow fan, an indoor heat exchanger, a controller and an outer casing, as shown in Figures 1 and 2, the panel structure of the outer casing consists of a front panel 5, a decorative strip 2, a light guide plate 1 Composed of light sources, the light guide plate 1 is fixed on the front panel 5, and under the light guide plate 1 is a decorative strip 2,

为了迎合不同消费者的喜好，在本空调室内机的面板边框结构上可作调整，具体是在导光板的四周以一矩形框包边，起到固定和美观的作用。In order to cater to the preferences of different consumers, the frame structure of the panel of the indoor unit of the air conditioner can be adjusted. Specifically, a rectangular frame is used around the light guide plate to play a fixed and beautiful role.

导光板1是一块厚度为3mm的长方形透明亚克力板，导光板的大小覆盖了室内机前面板的大部分区域。紧邻导光板1的下部侧边设有光源，光源是一组LED灯串3。在导光板1的下方是装饰条2，装饰条2上设有控制器窗口4，内置控制单元，用于温度显示、控制和信号感应。装饰条是不透明的，图1的装饰条上用虚线框起的部分是LED灯串的安装位置，从图2的A部放大图中看，装饰条2遮挡了安装在其后的LED光源，能够有效的隐藏LED灯，达到整体美感的效果。LED光源设在导光板1的下侧，LED灯串3发出的光直射向导光板1。通过导光板1使LED灯串3的点线光源转换为面光源。使光线变得柔和。The light guide plate 1 is a rectangular transparent acrylic plate with a thickness of 3 mm, and the size of the light guide plate covers most of the front panel of the indoor unit. A light source is provided adjacent to the lower side of the light guide plate 1 , and the light source is a group of LED light strings 3 . Below the light guide plate 1 is a decorative strip 2, on which there is a controller window 4 with a built-in control unit for temperature display, control and signal sensing. The decorative strip is opaque. The part framed by the dotted line on the decorative strip in Figure 1 is the installation position of the LED light string. From the enlarged view of Part A in Figure 2, the decorative strip 2 blocks the LED light source installed behind it. It can effectively hide the LED lights and achieve the overall aesthetic effect. The LED light source is arranged on the lower side of the light guide plate 1 , and the light emitted by the LED light string 3 is directed to the light guide plate 1 . The point line light source of the LED light string 3 is converted into a surface light source through the light guide plate 1 . Softens the light.

多个LED灯连接成LED灯串设在导光板的下方。LED灯的组合设计方案有三种：A plurality of LED lamps are connected to form LED lamp strings and arranged under the light guide plate. There are three combinations of LED lights:

第一种方案，使用一排白色LED灯，通过导光材料使整个面板发光，可控制LED灯的电流来调节亮度。面板也可以印刷或贴图案，通过面板发光来照亮图案。The first solution uses a row of white LED lights to make the entire panel glow through light-guiding materials, and the current of the LED lights can be controlled to adjust the brightness. The panels can also be printed or affixed with a pattern that is illuminated by emitting light from the panel.

第二种方案，采用红、绿、蓝三基色LED灯的其中一种，光的亮度和颜色通过控制LED灯管脚的电流值来实现。The second solution is to use one of the three primary colors of red, green and blue LED lights, and the brightness and color of the light are realized by controlling the current value of the pins of the LED lights.

第三种方案，由不同红、绿、蓝三基色LED灯的组合及电流值的控制实现丰富多彩的显示颜色。The third solution is to achieve rich and colorful display colors by combining different red, green and blue primary color LED lights and controlling the current value.

在空调器的控制器内包括有LED灯串控制单元，储存有多种LED灯串的发光程序方式，可控制LED灯串发出白光、单色、多色光，并可根据压缩机运行状态或者是回风温度的高低变换发光模式，使空调室内机炫丽夺目、富有动感。举例说明如下：The controller of the air conditioner includes an LED light string control unit, which stores a variety of LED light string lighting programs, which can control the LED light string to emit white light, single-color, and multi-color light, and can be controlled according to the operating status of the compressor or The high and low temperature of the return air changes the light mode, making the indoor unit of the air conditioner dazzling and dynamic. Examples are as follows:

显示空调器工作状态：Display the working status of the air conditioner:

在制冷模式下，控制器控制LED灯串电流值I1，面板显示蓝色或其他冷色(由LED灯串的组合设计决定)，在制热模式下，控制器控制LED灯串电流值I2，面板显示橙色或其他暖色，在通风模式下，控制器控制LED灯串电流值I2，面板显示淡黄色。In the cooling mode, the controller controls the current value I1 of the LED light string, and the panel displays blue or other cool colors (determined by the combination design of the LED light string). In the heating mode, the controller controls the current value I2 of the LED light string, and the panel displays It displays orange or other warm colors. In the ventilation mode, the controller controls the LED light string current value I2, and the panel displays light yellow.

显示室内温度的情况：To display the room temperature:

LED灯串控制单元连接空调回风感温头并处理空调回风感温头信号，输出LED灯串的电流值控制信号。当检测到空调的回风温度＞31℃时，控制器控制LED灯串电流值I11，制冷模式面板显示浅蓝(制热模式显示深橙)，当回风温度＜18℃时，控制器控制LED灯串电流值I12，制冷模式面板显示深蓝(制热模式显示浅橙)，回风温度T在18℃＜T＜31℃时，控制器控制LED灯串不同的电流值，使面板颜色由浅渐深(或由深渐浅)，可以选择每改变2℃就转换一种颜色，从视觉上给用户一种冷暖感受。The LED light string control unit is connected to the return air temperature sensor of the air conditioner, processes the signal of the air conditioner return air temperature sensor, and outputs the current value control signal of the LED light string. When it is detected that the return air temperature of the air conditioner is greater than 31°C, the controller controls the current value of the LED light string I11, and the cooling mode panel displays light blue (the heating mode displays dark orange), and when the return air temperature is less than 18°C, the controller controls The current value of the LED light string is I12, the panel displays dark blue in the cooling mode (light orange in the heating mode), and when the return air temperature T is 18°C<T<31°C, the controller controls the different current values of the LED light string to make the panel color change from light to light Gradually darken (or gradually lighten from dark to dark), you can choose to change a color every time the temperature changes by 2°C, visually giving users a warm and cold feeling.
