Description

壁挂式空调室内机 技术领域
本发明涉及空调器，特别是涉及一种壁挂式空调室内机。
背景技术
越来越多的人们追求精致且有品味的生活，无论是在家庭还是办公室，空调室内机都成为人们生活的必需品。传统的壁挂式空调室内机外观单一，形状变化的局限性从一定程度上限制了空调性能的提高。
同一台普通空调室内机送出的各区域的风速和风温基本是一致的，然而，由于处于同一个屋子的不同人们在性别、年龄、体质等方面存在差异，导致其对温度、风速的敏感性不同，进而导致因为空调的温度、档位等问题产生分歧。
另外，空调室内机通过蒸发器与空气之间的热交换达到制冷或制热的目的，通常来讲，蒸发器的面积越大，热交换的效率就越高。传统的壁挂式空调室内机使用贯流风机驱动空气流动，在贯流风机的外侧半包裹着蒸发器。现有技术中普遍认为，这种使用贯流风机的室内机，其蒸发器面积不够大，换热效率都不高。为此，为了片面地追求较大的蒸发器面积，一些现有技术将贯流风机换成了轴流风机或离心风机。然而，单一的轴流风机或离心风机并不能满足正常的送风量需求，需要设置多个轴流风机或离心风机，而且轴流风机对进风口的位置有严格的要求，离心风机的风道结构较为复杂，且占用空间，导致这类壁挂式空调室内机的结构非常复杂，体积比较大，且运行噪音较大。
发明内容
本发明的一个目的旨在克服现有技术中的至少一个缺陷，提供一种结构简单、能够双区送风且具有强劲送风区和柔和送风区之分的壁挂式空调室内机。
本发明的一个进一步的目的是提高壁挂式空调室内机的换热效率。
本发明的另一个进一步的目的是提升壁挂式空调室内机的外观、提高其送风量。
为了实现上述目的，本发明提供一种壁挂式空调室内机，包括：
机壳，具有进风口和用于向室内送风的条形出风口，所述出风口处设有沿所述出风口的延伸方向并排设置的两个独立的导风板，每个所述导风板均配置成受控地绕其自身的平行于所述出风口延伸方向的转轴枢转，以用于调节所述出风口的与该导风板对应的出风区域的开闭状态和/或出风方向，两个所述导风板的转轴共线或平行；以及
贯流风机，配置成绕沿所述机壳横向延伸的转轴可转动地设置于所述机壳内，且包括半径从所述机壳的横向两端向其中间逐渐增大的变径叶轮。
可选地，所述壁挂式空调室内机还包括：
蒸发器，罩设在所述贯流风机上，且包括由后向前地依次相连的第一换热段、第二换热段和第三换热段，其中
所述第一换热段和所述第三换热段均呈由所述机壳的横向两端向其中间逐渐向背离所述贯流风机的外侧方向倾斜延伸的V形换热段或向该外侧方向凸出弯曲延伸的曲面换热段。
可选地，所述第一换热段处于所述贯流风机的后侧或后上侧，并由所述机壳的横向两端向其中间逐渐向后倾斜延伸；且/或
所述第三换热段处于所述贯流风机的前侧，并由所述机壳的横向两端向其中间逐渐向前倾斜延伸。
可选地，所述第一换热段和所述第三换热段的倾斜角度分别与所述变径叶轮的分别处于所述第一换热段和所述第三换热段所在侧的外轮廓线的倾斜角度相一致。
可选地，所述第二换热段处于所述贯流风机的上方或侧上方；且
所述第二换热段均为平面换热段，或者，所述第二换热段呈所述机壳的横向两端向其中间逐渐朝背离所述贯流风机的外侧方向倾斜的V形换热段。
可选地，所述机壳包括用于形成其前部的前面板，所述前面板的沿水平剖切面截出的横截面呈由所述机壳的横向两端向其中间逐渐向前倾斜的V形。
可选地，所述进风口形成在所述机壳的顶部，所述进风口的前侧边缘与所述前面板的顶部边缘相邻接。
可选地，所述出风口位于所述机壳的前侧底部；且
所述壁挂式空调室内机还包括导流板，其设置于所述机壳的底部且位于所述出风口的下方，并与所述机壳的底部之间形成引流间隙，以允许室内未 经换热的自然风经所述引流间隙由后向前地流动，从而与经所述出风口流出的换热后的气流相混合后送往室内。
可选地，所述导流板的沿垂直于前后方向的竖直剖切面截出的纵截面呈由所述机壳的横向两端向所述机壳的中间逐渐向下倾斜的V形。
可选地，所述壁挂式空调室内机还包括：
设置于所述机壳内的两个独立的导板电机，每个所述导板电机的转动输出轴均与相应的一个所述导风板的转轴相连，以受控地带动该导风板枢转；且
两个所述导板电机配置成以三种转动方式之一受控地转动，所述三种转动方式包括两个所述导板电机同步转动、两个所述导板电机异步转动、以及其中任一个所述导板电机转动，剩余一个所述导板电机停止。
本发明的壁挂式空调室内机采用贯流风机作为气流驱动部件，并且，贯流风机具有半径从机壳的横向两端向其中间逐渐增大的变径叶轮，在同转速下，叶轮的半径越大，吹出的风量和风速越大，因此，贯流风机的送风量可由其两个横向端部向其中部逐渐增大，在中间处达到最大，提高了中部区域的送风能力。本发明通过仅设置一个具有变径叶轮的贯流风机这一简单的设计即可在出风口的中部区域实现强劲送风、在其两个端部区域实现柔和送风，并由中间向两端柔和地过渡，同时满足了速冷速热用户、柔和舒适用户的不同需求。
进一步地，出风口处设有沿出风口的延伸方向并排设置的两个独立的导风板，每个导风板的状态、以及枢转的角度、速度等参数均可由用户自由设置，实现了多种模式的双区送风，满足了用户在不同区域的不同制冷制热需求，提高了用户的使用体验。
进一步地，本申请突破了传统的必须将贯流风机更换为其他风机类型才能够增大蒸发器面积的设计思想，在以贯流风机作为驱动送风装置的基础上对蒸发器结构进行改进，将三段式蒸发器的其中第一换热段和第三换热段特别设计成由机壳的横向两端向机壳的中间逐渐向背离贯流风机的外侧方向倾斜延伸的V形换热段或逐渐向该方向方向凸出弯曲延伸的曲面换热段，由此，在保证结构简单的基础上，同时增加了第一换热段和第三换热段的长度，从而增大了蒸发器整体的有效换热面积，进而提高了换热效率、提升了室内机的能耗等级。
进一步地，本申请将其机壳的前面板特别设计成使得前面板的沿水平剖切面截出的横截面呈由所述机壳的横向两端向所述机壳的中间逐渐向前倾斜的V形，可使得前面板与贯流风机的结构形式、以及蒸发器的第三换热段形状相匹配。由此，不但尽可能地缩小了壁挂式空调室内机的体积，使其符合小型化的发展趋势，而且还进一步增加了补风量，从而在很大程度上增大了壁挂式空调室内机的送风量。同时，V形的前面板在外形上给人耳目一新的科技感和高级感。可见，本发明仅通过将前面板设计成V形这一简单的结构设计，即可同时达到美观、提高送风量的多重效果。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
本发明提供一种壁挂式空调室内机，图1是根据本发明一个实施例的壁挂式空调室内机的示意性结构图，图2是根据本发明一个实施例的壁挂式空调室内机的示意性正视图，图3是根据本发明一个实施例的壁挂式空调室内机的示意性结构分解图，图4是根据本发明一个实施例的壁挂式空调室内机 沿水平面截取的示意性剖视图。
参见图1至图4，本发明的壁挂式空调室内机1包括机壳10，机壳10用于构成壁挂式空调室内机1的外壳。机壳10具有用于引入室内空气的进风口11和用于向室内送风的条形出风口12，出风口12处设有沿出风口12的延伸方向并排设置的两个独立的导风板131、132。每个导风板均配置成受控地绕其自身的平行于出风口12延伸方向的转轴枢转，以用于调节出风口12的与该导风板相对应的出风区域的开闭状态和/或出风方向，两个导风板131、132的转轴共线或平行。具体地，其中一个导风板131可位于出风口12的左侧区域，用于调节出风口12左侧区域的开闭状态和/或出风方向；另一个导风板132可位于出风口12的右侧区域，用于调节出风口12右侧区域的开闭状态和/或出风方向。导风板131和导风板132的转轴均平行于出风口12的延伸方向。例如，当出风口12沿机壳10的横向延伸时，导风板131和导风板132的转轴均沿横向延伸。由于两个导风板是独立的，因此，每个导风板的状态、以及枢转的角度、速度等参数均可由用户自由设置，实现了多种模式的双区送风，满足了用户在不同区域的不同制冷制热需求，提高了用户的使用体验。具体地，每个导风板均为沿其转轴方向延伸的细长型的板材。每个导风板均为平面板，以减小气流流经其的阻力，提高送风速度。或者，每个导风板均为中部朝机壳10的外侧凸出弯曲的曲面板，以引导气流流向机壳10的前侧下方，避免气流直向下吹。
特别地，壁挂式空调室内机1还包括贯流风机20，贯流风机20配置成绕沿机壳10横向延伸的转轴可转动地设置于机壳10内，且包括半径从机壳10的横向两端向其中间逐渐增大的变径叶轮21。也就是说，贯流风机20的叶轮半径从机壳10的横向两端向其中间逐渐增大。可以理解的是，在同转速下，叶轮的半径越大，吹出的风量和风速越大。因此，贯流风机20的送风量可由其两个横向端部向其中部逐渐增大，在中间处达到最大，提高了贯流风机20中部区域的送风能力。也即是，贯流风机20的送风量自其两个横向端部向其中部具有增大的趋势，贯流风机20的送风量在其中间处达到最大。本发明通过仅设置一个具有变径叶轮21的贯流风机20这一简单的设计即可在出风口12的中部区域实现强劲送风、在其两个端部区域实现柔和送风，并由中间向两端柔和地过渡，同时满足了速冷速热用户、柔和舒适用户的不同需求。
在本发明的一些实施例中，壁挂式空调室内机1还包括设置于机壳10内的两个独立的导板电机81、82，每个导板电机的转动输出轴均与相应的一个导风板的转轴相连，以受控地带动该导风板枢转。具体地，其中一个导风板131的转轴可与其中一个导板电机81的转动输出轴相连，以受控地带动该导板电机81枢转；另一个导风板132的转轴可与其中一个导板电机82的转动输出轴相连，以受控地带动该导板电机82枢转。
进一步地，两个导板电机81、82配置成以三种转动方式之一受控地转动，该三种转动方式包括两个导板电机81、82同步转动、两个导板电机81、82异步转动、以及其中任一个导板电机转动，剩余一个导板电机停止。由此，可实现多种模式的分区送风的目的，满足了不同区域用户的不同制热制冷需求。
在本发明的一些实施例中，壁挂式空调室内机1还包括蒸发器30，蒸发器30用于与流经其的气流进行热交换，从而产生温度较高(制热时)或温度较低(制冷时)的换热气流。图5是根据本发明一个实施例的蒸发器的示意性结构图。蒸发器30罩设在贯流风机20上，且包括由后向前地依次相连的第一换热段31、第二换热段32和第三换热段33。第一换热段31和第三换热段33均呈由机壳10的横向两端向其中间逐渐向背离贯流风机20的外侧方向倾斜延伸的V形换热段或向该外侧方向凸出弯曲延伸的曲面换热段。在本发明中，一个结构自一端朝向另一端逐渐向一个方向倾斜或凸出弯曲是指该结构自一端朝向另一端具有向该方向倾斜或凸出弯曲的趋势。需要注意的是，这里所说的外侧方向意指背离贯流风机20所在侧的方向，也是贯流风机20的径向外侧方向，相应地，朝向贯流风机20所在侧的方向为与该外侧方向相反的内侧方向，也是贯流风机20的径向内侧方向。
本申请突破了传统的必须将贯流风机更换为其他风机类型才能够增大蒸发器面积的设计思想，在以贯流风机20作为驱动送风装置的基础上对蒸发器结构进行改进，将三段式蒸发器的其中第一换热段31和第三换热段33特别设计成由机壳10的横向两端向机壳10的中间逐渐向背离贯流风机20的外侧方向倾斜延伸的V形换热段或逐渐向该外侧方向凸出弯曲延伸的曲面换热段，由此，在保证结构简单的基础上，同时增加了第一换热段31和第三换热段33的长度，从而在很大程度上增大了蒸发器30整体的有效换热面积，进而提高了换热效率、提升了室内机的能耗等级。
当第一换热段31和第三换热段33处于贯流风机20的不同侧时，二者背离贯流风机20的外侧方向也不相同。在本发明的一些实施例中，第一换热段31可处于贯流风机20的后侧或后上侧，此时，第一换热段31背离贯流风机20的外侧方向可以为向后的方向，第一换热段31由机壳10的横向两端向其中间逐渐向后倾斜延伸。第三换热段33处于贯流风机20的前侧，此时，第三换热段33背离贯流风机20的外侧方向可以为向前的方向，第三换热段33由机壳10的横向两端向其中间逐渐向前倾斜延伸。
在本发明的一些实施例中，第一换热段31和第三换热段33的倾斜角度可分别与变径叶轮21的分别处于第一换热段31和第三换热段33所在侧的外轮廓线的倾斜角度相一致。例如，在一个实施例中，第一换热段31处于贯流风机20的后侧，第一换热段31的倾斜角度与变径叶轮21后侧的外轮廓线的倾斜角度相一致。在一个实施例中，第三换热段33处于贯流风机20的前侧，第三换热段33的倾斜角度与变径叶轮21前侧的外轮廓线的倾斜角度相一致。由此，可使得第一换热段31与贯流风机20之间、以及第三换热段33与贯流风机20之间形成均匀的间隙，以确保稳定的送风，并尽可能地缩小蒸发器30和贯流风机20占用的空间，以减小壁挂式空调室内机1的体积，使其更加符合小型化的发展趋势。
在本发明的一些实施例中，第二换热段32处于贯流风机20的上方或侧上方。第二换热段32为平面换热段，或者，第二换热段32呈机壳10的横向两端向其中间逐渐朝背离贯流风机20的外侧方向倾斜的V形换热段，即第二换热段32可由机壳10的横向两端向其中间逐渐朝上倾斜延伸。第一换热段31与第二换热段32之间的朝向贯流风机20的内侧夹角、以及第二换热段32和第三换热段33之间的朝向贯流风机20的内侧夹角均小于平角，从而形成半包裹贯流风机20的状态，以获得较好的换热效果。
进一步地，第一换热段31的顶部边缘与第二换热段32的后侧边缘相邻接，且形状相一致。第二换热段32的前侧边缘与第三换热段33的顶部边缘相邻接，且形状相一致。
在本发明的一些实施例中，机壳10还包括用于形成其前部的前面板14。进一步地，机壳10还包括骨架16和罩壳17。特别地，前面板14的沿水平剖切面截出的横截面呈由机壳10的横向两端向机壳10的中间逐渐向前倾斜的V形。也就是说，前面板14大致呈由机壳10的横向两端向机壳10的中 间逐渐向前倾斜的V形板材。由此，可使得前面板14与贯流风机20的结构形式以及第三换热段33的形状相匹配。一方面尽可能地缩小了壁挂式空调室内机1的体积，使其符合小型化的发展趋势；另一方面，还进一步增加了补风量，从而在很大程度上增大了壁挂式空调室内机1的送风量。同时，V形的前面板14在外形上给人耳目一新的科技感和高级感。可见，本发明仅通过将前面板14设计成V形这一简单的结构设计，即可同时达到美观、提高送风量的多重效果。
在本发明的一些实施例中，前面板14可包括竖直放置且对称设置的两个板体141，每个板体141均由其自身的位于机壳10横向端部的第一端141a向前倾斜地延伸至其自身的位于机壳10中部的第二端141b。也就是说，前面板14可以为竖直放置的V形板体，其V形的尖端朝向机壳10的前方。
进一步地，两个板体141的第二端141b以胶黏或其他合适的方式固定连接或者两个板体141一体成型。两个板体141的第二端141b的邻接处位于壁挂式空调室内机1的沿前后方向延伸的竖直平分面内。具体地，两个板体141的第二端141b的邻接处可以为一竖直延伸的线或面。
在一些替代性实施例中，前面板14也可以为竖向倾斜放置的V形板体，例如，前面板14的上端可向前倾斜。此时，两个板体141的第二端141b的邻接处可以为一竖向延伸且上端向前倾斜的线或面。
图6是根据本发明一个实施例的壁挂式空调室内机的示意性俯视图。在本发明的一些实施例中，进风口11可形成在机壳10的顶部，进风口11的前侧边缘111与前面板14的顶部边缘142相邻接，以使得进风口11的前侧边缘111与前面板14的顶部边缘142形状相一致。具体地，由于前面板14大致呈由横向两端向中间逐渐朝前凸出的V形板材，因此，前面板14的顶部边缘142以及进风口11的前侧边缘均大致呈由机壳10的横向两端向其中间逐渐朝前凸出的V形，从而使得进风口11的前侧中部朝前凸出，增大了进风口11的面积，从而增大了壁挂式空调室内机1的进风量，进一步增大了其送风量。
由于顶部进风口很容易落灰，为此，本申请进一步在进风口11的上方设置防尘机构112。图7是根据本发明一个实施例的防尘机构的示意性剖视图，图7中的直线箭头为气流流动方向。防尘机构112的内部形成有多条弯曲或弯折的导风通道1121，每条导风通道1121的第一端端口1121a均与室 内环境连通，第二端端口1121b均与进风口11连通，每条导风通道1221的第一端端口1121a均朝向斜下方，避免了灰尘落入导风通道1121中，进而避免了进风口11处落灰、积灰等问题，减轻了进风口11处过滤装置的负担。
在一些替代实施例中，进风口11也可以形成在机壳10的后部，为了保证正常的进风量，机壳10的后侧可设有一支架，以在壁挂式空调室内机1安装至墙面时保证机壳10与墙面之间间隔一定的距离，从而保证正常进风。
在本发明的一些实施例中，出风口12可位于机壳10的前侧底部。为了减少开模成本，降低开模难度，出风口12可仍然保持为沿横向延伸的均匀条形出风口。机壳10还包括设置在前面板14下端后侧的V形堵板15。堵板15的前侧底部边缘与前面板14的底部边缘相邻接，且形状相一致；堵板15的后侧底部边缘与出风口12的顶部边缘相邻接，且形状相一致，避免了进风气流与出风气流产生混流。
进一步地，在贯流风机20的驱动作用下，换热后的气流经出风口12流向室内。由于气流在出风口12处向前下方吹出，因此在出风口12的附近会形成一定的负压。壁挂式空调室内机1还包括导流板41，导流板41设置于机壳10的底部且位于出风口12的下方，并与机壳10的底部之间形成引流间隙43，以允许室内未经换热的自然风在负压作用下经引流间隙43由后向前地流动，从而与经出风口12流出的换热后的气流相混合后送往室内。由此，不但增大了壁挂式空调室内机1的送风量，而且送出的混合风较为柔和，更加趋向于人体正常的体感指数，提高了用户的舒适性体验。
无论壁挂式空调室内机1处于运行状态还是停机状态，导流板41始终处于机壳10的外部，导流板41会影响到整个壁挂式空调室内机1的外观效果，因此，导流板41的外形设计至关重要。为此，在本发明的一些实施例中，将导流板41特别设计成使其沿垂直于前后方向的竖直剖切面截出的纵截面呈由机壳10的横向两端向机壳10的中间逐渐向下倾斜的V形。由此，整个导流板41可以呈现出类似于跑车尾翼的V型设计，提高了导流板41的质感和高级感，从而提升了壁挂式空调室内机1的美观效果。
具体地，在一些实施例中，导流板41可以为一体成型的整块V型板体。在另一些实施例中，导流板41也可以由两块倾斜设置的平面板体固定连接组合而成，该两块平面板体的朝向机壳的内侧夹角为钝角。
壁挂式空调室内机1还可包括支撑架42，其固定连接于机壳10底部的 外侧，并用于支撑导流板41。
在一些实施例中，导流板41可以固定设置在机壳10的底部，此时，导流板41与机壳10底部之间形成的引流间隙43是固定不变的。
在另一些实施例中，导流板41也可以可动地设置于机壳10的底部，此时，导流板41与机壳10底部之间形成的引流间隙43的大小是可以调节的。图8是根据本发明另一个实施例的壁挂式空调室内机的示意结构图。在这些实施例中，壁挂式空调室内机1还可包括摆臂44，其第一端通过驱动装置45可枢转地连接于支撑架42，第二端与导流板41相连，以通过调节摆臂44相对于支撑架42的位置来调节导流板41相对于机壳10的位置，从而调节引流间隙43的大小和出风口12的出风方向，以调节室内机吹出的混合风中自然风的风量，从而调节壁挂式空调室内机1的送风温度和送风柔和度。
具体地，摆臂44的转动可以通过遥控器智能控制。驱动装置45可以为具有一个电机、多个减速齿轮组和若干辅助齿轮的驱动机构，也可以为具有两个电机、中心轴和若干辅助齿轮的驱动机构，还可以为具有电机和其他合适的传动部件的驱动机构。
进一步地，导流板41可包括朝向机壳10的上层板411和背离机壳10的下层板412，上层板411与下层板412相连，且上层板411为塑料件，下层板412为金属件，在保证导流板41的整体强度的同时减轻了导流板41的重量，从而减轻了驱动装置45的负荷，保证了导流板41能够可靠稳定地顺畅转动。
具体地，上层板411与下层板412之间可通过卡接的方式相连。上层板411的下表面与下层板412的上表面相贴合，上层板411的下表面与下层板412的上表面之间还可通过胶黏的方式加强连接。
在本发明的一些实施例中，壁挂式空调室内机1还包括气体传感器51、新风装置52、显示灯带53和灯带控制板54。
气体传感器51设置于机壳10上，用于检测室内环境中的二氧化碳的浓度。
新风装置52设置于机壳10内，且具有连通室外环境和机壳10内部空间的新风管，用于在室内环境中的二氧化碳浓度达到预设值后受控地启动运行，以向室内引入室外新风。具体地，该预设值可以为空气健康的临界值，当二氧化碳浓度高于该预设值时，通常认为空气环境是不健康的；当二氧化 碳浓度低于该预设值时，通常认为空气环境是健康的。当室内的二氧化碳浓度高于用于表征空间健康的该预设值时，新风装置52可受控地自动启动运行，向室内引入新风；当室内的二氧化碳浓度低于用于表征空间健康的该预设值时，新风装置52可受控地自动停止运行。
显示灯带53和灯带控制板54相连，灯带控制板54与气体传感器51相连，以根据气体传感器51检测到的二氧化碳浓度控制显示灯带53显示相应的颜色。也就是说，当室内的二氧化碳浓度不同时，显示灯带53显示的颜色也不同，由此，可通过颜色直观地表明目前室内的空气质量状况。
进一步地，壁挂式空调室内机1还包括支撑安装板55，其设置于机壳10内且相邻地位于前面板14的后侧。气体传感器51、显示灯带53和灯带控制板54均安装在支撑安装板55上。前面板14上可开设有感应通孔，气体传感器51与感应通孔相对，以通过感应通孔检测室内环境中的二氧化碳浓度。前面板14的与显示灯带53前后相对应的区域可设置成透明的。
在本发明的一些实施例中，壁挂式空调室内机1还包括语音交互系统60，图9是根据本发明一个实施例的语音交互系统的示意性结构框图。语音交互系统60可包括语音接收模块61、语音识别模块62、语音中心控制板63和语音播放模块64。语音接收模块61用于接收从周围环境输入的语音信号。语音识别模块62用于在唤醒状态下识别上述语音信号，并生成相应的语音指令。语音中心控制板63用于在上述语音信号为唤醒信号时唤醒语音识别模块62，并根据语音识别模块62识别生成的语音指令生成相应的控制指令和反馈信息。语音播放模块64用于根据上述控制指令和上述反馈信息播放相应的语音信息。上述语音信号不仅可包括简单的开启、关闭、制冷模式、制热模式、运行温度等简单的语音调节信号，还可以包括预报天气、点歌等其他合适的复杂的语音信号。
具体地，语音接收模块61可为设置在前面板14后侧的麦克风，语音播放模块64为设置在前面板14后侧的音响，麦克风和音响可均安装在支撑安装板55上。
