Description

用于空调器的导风板及空调器 技术领域
本发明属于空调器技术领域，具体提供一种用于空调器的导风板及空调器。
背景技术
空调器是能够对室内进行制冷和/或制热的设备。
空调器包括室内机和室外机，室内机包括壳体，壳体上设置有出风口，在出风口处设置有导风板，通过导风板可以改变出风方向，扩大送风范围。然而，在空调器制冷运行时，受冷风的影响，导风板的温度会比较低，然而，室内的空气温度是比较高的，当热空气与低温的导风板接触后，热空气中的水分被冷凝，使得导风板的外表面产生凝露，当导风板上的凝露比较多时，会滴落到地面、桌面或者床上，给用户带来极大地困扰，严重影响用户的使用体验。
公开号为CN209991595U的专利文献公开了一种可避免凝露的空调导风板出风结构以及空调导风板，该空调导风板出风结构包括开设在空调导风板上的出风孔，还包括设置在空调导风板的后侧面并紧邻在出风孔的上方的凸台，出风孔用于通过冷风。也就是说，通过在导风板上开设出风孔，使导风板内侧的冷风分流一部分到导风板的外侧，从而隔绝热空气，避免热空气与导风板接触，从而避免导风板上产生凝露。
因此，本领域需要一种新的用于空调器的导风板及相应的空调器来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有空调器的导风板的外表面易产生凝露的问题，本发明提供了一种用于空调器的导风板，所述空调器包括室内机，所述室内机的壳体上设置有出风口，所述导风板设置在所述出风口处，所述导风板上设置有诱引孔，所述诱引 孔的进风端位于所述导风板的外表面，所述诱引孔的出风端位于所述导风板的内表面，所述诱引孔从所述进风端到所述出风端朝所述导风板的前端倾斜，以便在空调器运行时将所述导风板外侧的空气诱引至所述导风板的内侧并因此与所述出风口内的空气相混合。
在上述导风板的优选技术方案中，所述诱引孔的轴线与所述导风板的厚度方向的夹角为60度至70度。
在上述导风板的优选技术方案中，所述导风板的前端设置有朝向所述导风板的内侧倾斜延伸的引风结构，以便在所述导风板转动至设定工作位置时使所述出风口吹出的风沿水平方向流动。
在上述导风板的优选技术方案中，所述诱引孔与所述引风结构近似平行设置，以便在所述导风板转动至所述设定工作位置时，使得所述诱引孔呈近似水平的状态。
在上述导风板的优选技术方案中，所述壳体上设置有气体增速结构，所述气体增速结构设置为在所述导风板转动至设定工作位置时，能够通过减小所述出风口处的出风通道的横截面积的方式来增加所述出风口处的气体的流速。
在上述导风板的优选技术方案中，所述诱引孔靠近所述导风板与所述气体增速结构相对应的位置设置。
在上述导风板的优选技术方案中，所述进风端和所述出风端沿所述导风板的宽度方向错位布置。
在上述导风板的优选技术方案中，沿所述导风板的宽度方向上设置有两排所述诱引孔，每个所述诱引孔沿所述导风板的长度方向设置成长条状。
在上述导风板的优选技术方案中，所述诱引孔的宽度为2mm至10mm
在另一方面，本发明还提供了一种空调器，所述空调器包括上述的导风板。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过在导风板上设置诱引孔，诱引孔的进风端位于导风板的外表面，诱引孔的出风端位于导风板的内表面，诱引孔从进风端到出风端朝导风板的前端倾斜，以便在空调器运行时将导风板外侧的空气诱引至导风板 的内侧并因此与出风口内的空气相混合。通过这样的设置，当空调器制冷运行时，使得位于导风板外侧的热空气能够通过诱引孔流到导风板的内侧并因此与出风口内的冷空气相混合，具体而言，是因为在空调器运行时，出风口内的气体流速比较快，使得导风板内侧的气压降低，此时，导风板外侧的气压较高，在气压的作用下，位于导风板外侧的热空气被吸入至导风板的内侧，也可以说是位于导风板外侧的热空气被诱引至导风板的内侧，然后与出风口内的冷空气进行混合，从而提升出风口内的空气的温度，使得导风板的温度也就不再那么低，也就相当于提升了导风板的温度，导风板的温度高了，就不会使空气中的水分冷凝，从而能够避免导风板的外表面产生凝露。
进一步地，诱引孔的轴线与导风板的厚度方向的夹角为60度至70度。通过这样的设置，能够提高防凝露的效果。具体而言，发明人研究发现，虽然空调器的导风板可以有多个开启角度，但是，现有的空调器的导风板的常用开启角度一般为20度至30度，如果空调器的导风板的常用开启角度为30度，则可以将诱引孔的轴线与导风板的厚度方向的夹角设置为60度，当导风板开启至30度时，此时，诱引孔呈水平的状态，使得位于导风板外侧的空气更容易被诱引至导风板的内侧，防凝露的效果更好。
进一步地，诱引孔与引风结构近似平行设置，以便在导风板转动至设定工作位置时，使得诱引孔呈近似水平的状态。通过这样的设置，在空调器工作时，导风板会转动到设定工作位置，以使引风结构大致呈水平的状态，从而使得出风口吹出的风能够沿水平方向流动，与此同时，诱引孔也大致呈水平的状态，使得位于导风板外侧的空气更容易被诱引至导风板的内侧，防凝露的效果更好。
进一步地，壳体上设置有气体增速结构，气体增速结构设置为在导风板转动至设定工作位置时，能够通过减小出风口处的出风通道的横截面积的方式来增加出风口处的气体的流速。通过这样的设置，能够提高出风口处的气体的流动速度，气体的流速越快，导风板内侧的气压越低，吸力也就越强，也就能够将更多的位于导风板外侧的热空气诱引至导风板的内侧，从而提高防凝露的效果；此外，气体的流动速度越快，传播速度也就越快，传播距离也就越长，能够尽快降低室内的温度。
进一步地，诱引孔靠近导风板与气体增速结构相对应的位置设置。通过这样的设置，能够进一步提高诱引能力，从而进一步提高防凝露的效果。
进一步地，进风端和出风端沿导风板的宽度方向错位布置。通过这样的设置，能够防止用户通过诱引孔看到空调器的内部结构，提升美观性。
此外，本发明在上述技术方案的基础上进一步提供的空调器由于采用了上述的导风板，因而具备了上述导风板所具备的技术效果，相比于现有的空调器，本发明的空调器在制冷运行时，可以避免导风板上产生凝露，从而避免影响用户的使用体验。

基于背景技术指出的现有空调器的导风板的外表面易产生凝露的问题，本发明提供了一种用于空调器的导风板及空调器，旨在避免导风板上产生凝露。
具体地，本发明的空调器包括室外机和室内机，室外机主要包括压缩机、冷凝器、气液分离器、四通换向阀等元器件，如图1和图2所示，室内机主要包括壳体1以及设置在壳体1内的换热器(图中未示出)和风扇(图中未示出)等，壳体1上设置有出风口11，在出风口11处设置有导风板2，导风板2与壳体1转动连接，通过调整导风板2的转动角度可以改变出风方向。
由背景技术可知，在空调器制冷运行时，受冷风的影响，导风板2的温度会比较低，然而，室内的空气温度是比较高的，当热空气与低温的导风板2接触后，热空气中的水分被冷凝，使得导风板2的外表面产生凝露，为此，如图1和图2所示，本发明在导风板2上设置了诱引孔21，诱引孔21的进风端211位于导风板2的外表面，诱引孔21的出风端212位于导风板2的内表面，诱引孔21从进风端211到出风端212朝导风板2的前端倾斜，以便在空调器运行时，能够将位于导风板2外侧的空气诱引至导风板2的内侧，并因此与出风口11内的空气相混合。
如图1所示，导风板2处于闭合状态，导风板2上露在外面的面即为导风板2的外表面，也就是我们可以看到的这个面，与外表面相对的即为导风板2的内表面，导风板2的前端指的是靠近壳体1的最外沿的一端。
如图2所示，当空调器制冷运行时，位于导风板2外侧的热空气能够通过诱引孔21流到导风板2的内侧，然后与出风口11内的冷空气相混合，具体而言，是因为在空调器运行时，出风口11内的气体流速比较快，使得导风板2内侧的气压降低，此时，导风板2外侧的气压高于导风板2内侧的气压，在大气压的作用下，位于导风板2外侧的热空气被吸入至导风板2的内侧，也可以说是位于导风板2外侧的热空气被诱引至导风板2的内侧，然后与出风口11内的冷空气相混合，形成混合空气，从而提升出风口11内的空气的温度，使得导风板2的温度也就不再那么低，也就相当于提升了导风板2的温度，导风板2的温度高了，就不会使空气中的水分冷凝，从而能够避免导风板2的外表面产生凝露。
其中，可以将诱引孔21设置为圆形孔、方形孔或者长条形孔等，此外，在导风板2的宽度方向上，可以设置一排诱引孔21，也可以设置多排诱引孔21，等等，这种对诱引孔21的具体形状以及具体布置方式的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
需要说明的是，与公开号为CN209991595U的专利文献公开的空调导风板相比，本发明采用了完全不同的技术手段来解决导风板2的外表面易产生凝露的问题，发明构思是完全不同，具体而言，公开号为CN209991595U的专利是通过将导风板内侧的冷空气分流至导风板的外侧，以阻隔热空气与导风板接触，从而能够避免热空气中的水分被冷凝，进而避免导风板的外表面上产生凝露；而本发明是通过将导风板2外侧的热空气诱引至导风板2的内侧，与出风孔11内的冷空气进行混合，形成混合空气，提升出风口11处的气体的温度，从而避免导风板2的温度过低，使得导风板2无法将热空气中的水分冷凝，进而避免导风板2的外表面上产生凝露，换言之，可以将导风板2看作冷凝器，公开号为CN209991595U的专利是通过切断热空气与导风板2(冷凝器)之间的接触来避免热空气中的水分被冷凝，而本发明直接使得导风板2无法成为 冷凝器，相当于“直接消灭了冷凝的源头”，没有冷凝器了，自然就无法使热空气中的水分冷凝了。
此外，还需要说明的是，与公开号为CN209991595U的专利文献公开的空调导风板相比，本发明的导风板2能够获得更优的技术效果，首先，本发明的导风板2能够更有效地避免产生凝露，具体而言，从上面的发明构思的对比可知，本发明是“直接消灭了冷凝的源头”，而公开号为CN209991595U的专利是避免与导风板(冷凝的源头)接触，换言之，一个是直接消灭“冷凝源”，一个是避免与“冷凝源”接触，两者相比，当然是直接消灭“冷凝源”的方式更加有效，效果更好；其次，本发明能够避免出风口11直接吹冷风，具体而言，本发明通过使导风板2外侧的热空气与导风板2内侧的冷空气进行混合，提高了出风口11处气体的温度，使得该出风温度更加适合，吹在用户的身上更加舒适，用户体验更加；然而，公开号为CN209991595U的专利与本发明恰恰相反，该专利直接将导风板内侧的冷空气分流至导风板的外侧，使得冷空气更容易直接吹到用户身上，使用户感到不适。
综上所述，与公开号为CN209991595U的专利相比，本发明能够通过更为有效的技术手段来解决该专利中的技术问题，并且能够获得相比于该专利更为显著的技术效果。
优选地，如图3所示，诱引孔21的轴线与导风板2的厚度方向的夹角a为60度至70度。发明人研究发现，虽然空调器的导风板2可以有多个开启角度，但是，现有的空调器的导风板2的常用开启角度一般为20度至30度，即导风板2与水平面的夹角b一般为20度至30度，如果空调器的导风板2的常用开启角度为30度，即夹角b为30度，则将诱引孔21的轴线与导风板2的厚度方向的夹角a设置为60度，当导风板2开启至30度时，因为夹角a和夹角b之和正好是90度，此时，诱引孔21呈水平的状态，使得位于导风板2外侧的空气更容易被诱引至导风板2的内侧，防凝露的效果更好。也就是说，在实际应用中，可以根据空调器的导风板2的常用开启角度b的具体值，来设定诱引孔21的轴线与导风板2的厚度方向的夹角a的具体值，使夹角a与夹角b的和等于90度，这样的话，在空调器运行时，可以使诱引孔21呈水平的状态，在 这种情形下，位于导风板2外侧的空气更容易被诱引至导风板2的内侧，防凝露的效果更好。
优选地，如图2和图3所示，导风板2的前端设置有朝向导风板2的内侧倾斜延伸的引风结构22，以便在导风板2转动至设定工作位置时，能够使出风口11吹出的风沿水平方向流动。通过设置引风结构22，能够防止出风口11吹出的风直接向下吹到用户的身上，也就是说，在导风板2转动至设定工作位置时，引风结构22大致呈水平的状态，使得从出风口11吹出的风可以沿水平方向流动，防止风直接向下吹到用户的身上，提升用户使用体验。进一步优选地，诱引孔21与引风结构22近似平行设置，以便在导风板2转动至设定工作位置时，使得诱引孔21呈近似水平的状态。也就是说，在空调器工作时，导风板2会转动到设定工作位置，以使引风结构22大致呈水平的状态，从而使得出风口11吹出的风能够沿水平方向流动，与此同时，诱引孔21也大致呈水平的状态，使得位于导风板2外侧的空气更容易被诱引至导风板2的内侧，防凝露的效果更好。
优选地，如图2所示，壳体1上设置有气体增速结构12，气体增速结构12设置为在导风板2转动至设定工作位置时，能够通过减小出风口11处的出风通道的横截面积的方式来增加出风口11处的气体的流速。当导风板2转动到设定工作位置时，气体增速结构12与导风板2之间的垂直距离明显小于壳体1其它位置与导风板2之间的垂直距离，此处的出风通道的横截面积最小，当气体流经此处时，能够使气体加速，气体的流速越快，导风板2内侧的气压越低，吸力也就越强，能够将更多的位于导风板2外侧的热空气诱引至导风板2的内侧，提高防凝露的效果，此外，气体的流动速度越快，传播速度也就越快，传播距离也就越长，能够尽快降低室内的温度。进一步优选地，诱引孔21靠近导风板2与气体增速结构12相对应的位置设置。需要指出的是，导风板2与气体增速结构12相对应的位置指的是导风板2上与气体增速结构12之间的距离最短的位置，该位置对应的出风通道内的气体的流动速度最快，将诱引孔21靠近该位置设置，能够将更多的位于导风板2外侧的热空气诱引至导风板2的内侧，提高防凝露的效果。
优选地，如图4和图5所示，诱引孔21的进风端211和出风端212沿导风板2的宽度方向错位布置。具体而言，如图5所示，图中的点画线表示的是导风板2的厚度方向，进风端211的右侧边线与左侧的点画线重合，出风端212的左侧边线与右侧的点画线重合，在沿导风板2的宽度方向上，进风端211位于左侧，出风端212位于右侧，并且两者之间没有重叠的部分，通过这样的设置，能够防止用户通过诱引孔21看到空调器的内部结构，能够提升美观性。
需要说明的是，为了便于理解，图5中所示的进风端211的右边线与出风端212的左边线之间在沿导风板2的宽度方向上具有一定的距离，即图中所示的间距L大于0，实际上，当间距L等于0时，即进风端211的右侧边线与出风端212的左侧边线重合时，也能够防止用户通过诱引孔21看到空调器的内部结构，也就是说，只要使间距L大于或者等于0即可。
优选地，如图6所示，沿导风板2的宽度方向上设置有两排诱引孔21，每个诱引孔21沿导风板2的长度方向设置成长条状。其中，每排上设置有多个长条状的诱引孔21，当然，也可以将位于同一排上的多个长条状的诱引孔21直接拉通，变成一个整的长条状的诱引孔21。通过发明人反复试验验证，当诱引孔21的宽度为2mm至10mm时，防凝露的效果非常显著。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
