Description

立式空调室内机 技术领域
本发明涉及空调装置，特别是涉及一种立式空调室内机。
背景技术
现有的一些立式空调室内机的换热器模块设有电辅热结构，用于增强室内机的制热能力，从而快速地调整室内温度。电辅热结构通常设置于换热器的前侧，由于受到室内机内部空间的限制，电辅热结构通常会邻近室内机的贯流风机。
然而，对于现有的另一些设有两个上下排布的贯流风扇的立式空调室内机来说，由于其两个贯流风扇之间会设置轴承座和风道分隔件，因此并不是很适合使用上述电辅热结构。也许正是由于这个原因，现有技术中的具有上下排布的两个贯流风扇的立式空调室内机始终没有应用电辅热结构，因此也不具备较高的快速调整室内温度的制热能力。
发明内容
本发明的一个目的旨在突破现有技术中的局限，提供一种送风范围较大、且能够快速调整室内温度的立式空调室内机。
本发明的一个进一步的目的是有效地避免辅助加热器产生的高温对每两个贯流风扇之间的轴承座组件产生安全性的危害。
本发明的另一个进一步的目的是对辅助加热器的对应于每个轴承座组件的区域所产生的热量进行有效利用。
为了实现上述目的，本发明提供一种立式空调室内机，包括：
机壳，其前侧设有竖向排列的多个出风口，其后侧设有进风口；
换热器，设置在所述机壳内，并用于与流经其的空气进行热交换；
至少两个贯流风扇，沿竖向依次排列在所述机壳内，且所述至少两个贯流风扇的轴线共线，每个所述贯流风扇均配置成促使空气经所述进风口进入所述机壳内、并与所述换热器换热后从对应的所述出风口吹出；以及
辅助加热器，沿竖向延伸地设置在所述至少两个贯流风扇的邻侧，以在所述立式空调室内机制热运行时对所述至少两个贯流风扇驱动的空气进行 辅助加热；其中
每相邻两个所述贯流风扇之间均设有一用于容装风扇轴承的轴承座组件，所述轴承座组件与所述辅助加热器之间设有用于保护所述轴承座组件的第一保护件，所述第一保护件由不可燃材料制成。
可选地，所述辅助加热器的与所述轴承座组件相对应的区段包缚有第二保护件，所述第二保护件与所述第一保护件的材质相同。
可选地，所述第一保护件包括叠加设置的至少一层第一保护板，每个所述第一保护板均为L型板材，所述L型板材覆盖所述轴承座组件的与所述辅助加热器相对的第一侧部以及与所述第一侧部相邻的第二侧部。
可选地，所述第一保护件与所述辅助加热器之间设有散热装置，所述散热装置配置成吸收所述辅助加热器与所述轴承座组件相对应区域所产生的至少部分热量，并传导至所述轴承座组件之外，以使该至少部分热量在所述贯流风扇的驱动作用下送往所述出风口。
可选地，所述散热装置包括贴设于所述第一保护件的传热板、设置于所述传热板外表面的多个散热片以及穿设在多个所述散热片之间的导热管。
可选地，所述轴承座组件的与所述辅助加热器相对的侧部设有附加风道，所述附加风道内设有附加风机，所述附加风机配置成促使空气流入所述附加风道、并吸收所述辅助加热器与所述轴承座组件相对应区域所产生的至少部分热量后流出所述附加风道。
可选地，每个所述轴承座组件均包括用于容装风扇轴承的轴承座和设置在所述轴承座的周向外侧并用于分隔位于其上方和下方的两个贯流风扇所处空间的风道分隔件；且
所述附加风道形成在所述轴承座和所述风道分隔件的侧壁之间。
可选地，所述轴承座与所述风道分隔件一体成型。
可选地，所述轴承座组件的至少与所述辅助加热器相对的侧部设有储水腔，所述储水腔的顶部设有通孔，以利用所述辅助加热器的与所述轴承座组件相对的区域所产生的热量促使所述储水腔内的水从所述通孔蒸发出来，并在所述贯流风扇的驱动作用下送往所述出风口，从而对从所述出风口送出的气流进行加湿。
可选地，所述储水腔包括相连通的第一子腔和第二子腔，所述第一子腔位于所述轴承座组件的与所述辅助加热器相对的第一侧部，所述第二子腔位 于所述轴承座组件的与所述第一侧部相邻的第二侧部；且
所述第二侧部处于所述至少两个贯流风扇的进风区域或出风区域内，所述通孔形成在所述第二子腔的顶部。
为了突破现有技术的局限，本申请的发明人在上下排列的至少两个贯流风扇的邻侧设置辅助加热器，从而利用辅助加热器对贯流风扇驱动的气流进行辅助加热，从而提高了整个立式空调室内机的制热能力，能够快速地调整室内的温度。同时由于至少两个贯流风扇上下排列，因此，扩大了立式空调室内机在上下方向上的送风范围，有利于室内温度的均衡性，提高了用户的舒适度体验。
进一步地，本申请的发明人意识到，限于立式空调室内机的内部空间，相邻两个贯流风扇之间的轴承座组件与辅助加热器的距离较近，其受辅助加热器的影响较大。因此，本发明在轴承座组件与辅助加热器之间设置用于对轴承座组件进行保护的第一保护件，能够减小辅助加热器产生的高温对轴承座组件的危害，降低了火灾隐患。进一步地，本发明还将第一保护件的材料特别设计成不可燃材料，可完全杜绝火灾隐患，对轴承座组件进行有效地保护。
进一步地，本发明还在辅助加热器和轴承座组件之间特别设置散热装置，可利用散热装置将辅助加热器与轴承座组件相对应区域所产生的至少部分热量传导至轴承座组件之外，以使该至少部分热量在贯流风扇的驱动作用下随气流送往出风口，从而使出风口送出的气流温度升高。或者，本发明还在轴承座组件的至少与辅助加热器相对的侧部特别设置带有附加风机的附加风道，能通过附加风机驱动空气流入附加风道，附加风道内的空气吸收辅助加热器与轴承座组件相对应区域所产生的至少部分热量形成温度较高的热空气，热空气在附加风机的驱动下流出附加风道，进而在贯流风扇的驱动作用下送往出风口，从而使出风口送出的气流温度升高。或者，本发明还在轴承座组件的至少与辅助加热器相对的侧部特别设置储水腔，辅助加热器的与轴承座组件相对应区域所产生的至少部分热量被储水腔中的水吸收而形成水汽，水汽通过通孔蒸发出来，进而在贯流风扇的驱动作用下送往出风口，从而能够对出风口送出的气流进行加湿，改善了因空调制热导致室内空气干燥的问题。上述三种方式均提高了用户的使用体验，有效地利用了辅助加热器的对应于每个轴承座组件的区域所产生的热量，减少了辅助加热器的热量 损失。

具体实施方式
本发明实施例提供一种立式空调室内机，图1是根据本发明一个实施例的立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立式空调室内机的示意性结构分解图。参见图1和图2，本发明实施例的立式空调室内机1一般性地可包括机壳10、换热器20和至少两个贯流风扇30。其中，机壳10的前侧设有竖向排列的多个出风口111，其后侧设有进风口121。具体地，机壳10内部限定有容纳空间，以容纳贯流风扇和换热器20。机壳10可包括位于前侧的前面板110和位于后侧的进风格栅120，多个出风口111 开设在前面板110上，进风口121开设在进风格栅120上。前面板110后侧还可设有出风框组件90，其上设有用于引导和调节出风口111的出风方向的摆叶。换热器20设置在机壳10内，用于与流经其的空气进行热交换，其与压缩机、冷凝器、节流装置、连接管路以及其他配件共同构成蒸汽压缩制冷循环***，实现空调的制冷/制热，具体原理和结构在此不再赘述。
上述至少两个贯流风扇30沿竖向依次排列在机壳10内，且该至少两个贯流风扇30的轴线共线。即至少两个贯流风扇30在机壳10内沿上下排列依次排列，每个贯流风扇30的轴线均沿竖向延伸，所有贯流风扇30的轴线共线设置。每个贯流风扇30均对应一个或一部分出风口111，且配置成促使空气经进风口121进入机壳10内、并与换热器20换热后从对应的出风口121吹出，实现了室内空气与换热器20的强制对流换热，提升了换热器20的换热效率。同时由于至少两个贯流风扇30上下排列，因此，扩大了立式空调室内机1在上下方向上的送风范围，有利于室内温度的均衡性，提高了用户的舒适度体验。
特别地，立式空调室内机1还包括辅助加热器40，辅助加热器40沿竖向延伸地设置在上述至少两个贯流风扇30的邻侧(需要说明的是，这里所说的“邻侧”意指邻近的侧部，也即是周围)，以在立式空调室内机1制热运行时对上述至少两个贯流风扇30驱动的空气进行辅助加热。也就是说，在立式空调室内机1制热运行时，辅助加热器40能够额外地为由进风口121进入的空气提供热量，从而提高了整个立式空调室内机1的制热能力，能够快速地调整室内的温度。
具体地，辅助加热器40可大致呈沿竖向延伸的长条形加热器，其高度可大致与上述至少两个贯流风扇30的高度之和相当，以使送风温度更加均衡。辅助加热器40优选为结构较为简单的电加热器，其具体可以翅片式加热器、电加热管、陶瓷加热元件等等。
图3是根据本发明一个实施例的立式空调室内机的示意性部分结构图，图4是根据本发明一个实施例的立式空调室内机的示意性部分结构分解图。参见图2至图4，进一步地，每相邻两个贯流风扇30之间均设有一用于容装风扇轴承的轴承座组件50。本申请的发明人意识到，限于立式空调室内机1的内部空间，相邻两个贯流风扇30之间的轴承座组件50与辅助加热器40的距离较近，其受辅助加热器40的影响较大。为此，本发明在轴承座组件 50与辅助加热器40之间设有用于保护轴承座组件50的第一保护件60，能够减小辅助加热器40产生的高温对轴承座组件50的危害，降低了火灾隐患。优选地，第一保护件60由不可燃材料制成，相比于阻燃材料来说，本发明采用不可燃材料可完全杜绝火灾隐患，对轴承座组件50进行全面地、有效地保护。第一保护件60的不可燃材料例如可以为钢材。
在图1至图2所示实施例中，贯流风扇30的数量为两个。相应地，轴承座组件50的数量为一个。具体地，处于上方的贯流风扇30的额定风量大于处于下方的贯流风扇30的额定风量，处于上方的贯流风扇30的对应的全部出风口的总过流面积大于处于下方的贯流风扇30对应的全部出风口的总过流面积。具体地，出风口111的数量可以为三个，三个出风口111的形状大小均相同，处于上方的贯流风扇30可对应两个出风口111，处于下方的贯流风扇30可对应一个出风口111。由此，仅通过控制两个贯流风扇30的开闭即可实现三个风量档的送风模式的切换，风量从小到依次为：仅开启处于下方的贯流风扇30的模式、仅开启处于上方的贯流风扇30的模式以及同时开启两个贯流风扇30的模式。并且，在这三种风量档送风模式下，再通过改变贯流风扇的风速，能够获取更加多样的送风模式，以满足用户的不同的需求，提升用户体验。
在本发明的一些实施例中，辅助加热器40的与轴承座组件50相对应的区段包缚有第二保护件41，第二保护件41与第一保护件60的材质相同，以进一步有效地保护轴承座组件。即第二保护件41也由不可燃材料制成。第二保护件41可以呈缠绕在辅助加热器40的与轴承座组件50相对应区段上的方环形构件。
在本发明的一些实施例中，第一保护件60包括叠加设置的至少一层第一保护板，每个第一保护板均为L型板材。轴承座组件50的与辅助加热器40相对的第一侧部和与第一侧部相邻的第二侧部可均镂空设置，此时，该L型板材以遮挡的形式覆盖轴承座组件50的第一侧部以及第二侧部。在一些替代性实施例中，轴承座组件50的第一侧部以及第二侧部也可以为封闭的，此时，该L型板材以贴附的形式覆盖在轴承座组件50的第一侧部以及第二侧部，例如该L型板材可贴附在轴承座组件50的与辅助加热器40相对的第一侧壁的外表面以及与第一侧壁相邻的第二侧壁的外表面。第一保护板的数量可以为一层，也可以为两层以上的多层。第一保护板60可通过胶黏、卡 接或其他合适的方式固定在轴承座组件50的侧壁。
在本发明的一些替代性实施例中，第一保护板也可以为平板型板材，其仅设置于轴承座组件50的与辅助加热器40相对的侧部。
进一步地，每个轴承座组件50均包括用于容装风扇轴承的轴承座51，相邻地设置在该轴承座组件50上方和下方的两个贯流风扇30的轴承安装于轴承座51中。轴承座51可以大致呈中空的圆柱体。每个轴承座组件50还包括设置在轴承座51的周向外侧并用于分隔位于其上方和下方的两个贯流风扇30所处空间的风道分隔件52，以避免两个贯流风扇30的送风相互干扰。第一保护件60设置于风道分隔件52的侧部。立式空调室内机1还包括风道组件70，其竖立在上述至少两个贯流风扇30的周向外侧，以用于将空气从换热器20处向前引流至多个出风口111处，风道分隔件52可将位于其上方和下方的两个贯流风扇30所处的风道组件70内的空间分隔开，从而避免两个贯流风扇30的送风相互干扰。风道分隔件52的形状可以为不规则的异形，只要与风道组件70相匹配即可。
更进一步地，轴承座51可与风道分隔件52一体成型。或者，轴承座51可通过卡接、焊接或其他合适的方式与风道分隔件52固定连接。
具体地，风道组件70包括竖向间隔设置的两个端板部730、740、蜗壳710以及蜗舌720。两个贯流风扇的驱动电机分别安装于端板部730和端板部740。蜗壳710竖立设置且连接在两个端板部730、740之间，蜗舌720同样竖立设置且连接在两个端板部730、740之间，并与蜗壳710共同引导空气流向。风道分隔件52连接在蜗壳710和蜗舌720之间。轴承座51内安装有分别与两个贯流风扇30的转轴相匹配的两个轴承，以便于安装两个贯流风扇。
图5是根据本发明另一个实施例的立式空调室内机的示意性部分结构分解图。在本发明的另一些实施例中，轴承座组件50与辅助加热器40之间还设有散热装置80，散热装置80配置成吸收辅助加热器40与轴承座组件50相对应区域所产生的至少部分热量，并传导至轴承座组件50之外，以使该至少部分热量在贯流风扇30的驱动作用下随气流送往出风口111。也就是说，本发明能通过散热装置80将辅助加热器40的与轴承座组件50相对应区域所产生的至少部分热量传导至轴承座组件50之外，以使该至少部分热量在贯流风扇30的驱动作用下随气流送往出风口111，从而使出风口111 送出的气流温度升高，提高了用户的使用体验，有效地利用了辅助加热器40的对应于每个轴承座组件50的区域所产生的热量，减少了辅助加热器40的热量损失。
图6是图5所示实施例中的散热装置的示意性结构图。进一步地，散热装置80包括贴设于第一保护件60的传热板81、设置于传热板81外表面的多个散热片82以及穿设在多个散热片82之间的导热管83，以更加高效地将辅助加热器40对应于所述轴承座组件50的区域所产生的热量传递出去。具体地，多个散热片82可沿横向均匀地间隔排列，每相邻两个散热片82之间均设有一个导热管83。
更进一步地，传热板81在上下方向上的尺寸与第一保护件60在该方向上的尺寸相当，散热片82和导热管83均沿竖向延伸，且导热管83向上延伸出传热板81的上端第一预设距离和/或导热管83向下延伸出传热板81的下端第二预设距离。由此，可有效地将将辅助加热器40对应于所述轴承座组件50的区域所产生的热量传递至轴承座组件50的外部，便于在贯流风扇30的驱动下送往出风口111。
图7是根据本发明又一个实施例的立式空调室内机的示意性部分结构分解图。在本发明的又一些实施例中，轴承座组件50的至少与辅助加热器40相对的侧部设有附加风道53，附加风道53内设有附加风机54，附加风机54配置成促使空气流入附加风道53、并吸收辅助加热器40与轴承座组件50相对应区域所产生的至少部分热量后流出附加风道53。也就是说，本发明能通过附加风机54驱动空气流入附加风道53，附加风道53内的空气吸收辅助加热器40与轴承座组件50相对应区域所产生的至少部分热量形成温度较高的热空气，热空气在附加风机54的驱动下流出附加风道53，进而在贯流风扇30的驱动作用下送往出风口111，从而使出风口111送出的气流温度升高，提高了用户的使用体验，有效地利用了辅助加热器40的对应于每个轴承座组件50的区域所产生的热量，减少了辅助加热器40的热量损失。
图8是图7所示实施例中的轴承座组件的示意性结构图。进一步地，附加风道53的两端分别设有空气入口531和空气出口532，空气出口532处于上述至少两个贯流风扇30的进风区域或出风区域内，以便于从附加风道53送出的热空气能够在贯流风扇30的驱动作用下送往出风口111。
进一步地，附加风道53形成在轴承座51和风道分隔件52的侧壁之间。 也就是说，在这些实施例中，轴承座51和风道分隔件52形成了相对封闭的空间。具体地，风道分隔件52的侧壁包括与辅助加热器40相对的第一侧壁521和与第一侧壁521相邻的第二侧壁522。空气出口532开设在第二侧壁522上，附加风机54设置于空气出口532的内侧。附加风道53可包括形成在轴承座51和风道分隔件52的第一侧壁521之间的第一子风道和形成在轴承座51和风道分隔件52的第二侧壁522之间的第二子风道，空气入口531位于第一子风道的远离第二子风道的端部，空气出口532位于第二子风道。附加风机54可与空气出口532正对设置。
图9是根据本发明再一个实施例的立式空调室内机的示意性部分结构分解图。在本发明的再一些实施例中，轴承座组件50的至少与辅助加热器40相对的侧部设有储水腔，储水腔的顶部设有通孔55，以利用辅助加热器40的与轴承座组件50相对的区域所产生的热量促使储水腔内的水从通孔55蒸发出来，并在贯流风扇30的驱动作用下送往出风口111，从而对从出风口111送出的气流进行加湿。也就是说，辅助加热器40的与轴承座组件50相对应区域所产生的至少部分热量被储水腔中的水吸收而形成水汽，水汽通过通孔蒸发出来，进而在贯流风扇的驱动作用下送往出风口111，从而能够对出风口111送出的气流进行加湿，改善了因空调制热导致室内空气干燥的问题，提高了用户的使用体验，有效地利用了辅助加热器40的对应于每个轴承座组件50的区域所产生的热量，减少了辅助加热器40的热量损失。
图10是图9所示实施例中的轴承座组件的示意性结构图，图11是图10的示意性剖视图。参见图10和图11，储水腔包括相连通的第一子腔56和第二子腔57，第一子腔56位于轴承座组件50的与辅助加热器40相对的第一侧部，第二子腔57位于轴承座组件50的与第一侧部相邻的第二侧部。也即是第一子腔56与辅助加热器40相对，由于辅助加热器40的遮挡，第一子腔56上方的区域风速较小，不利于水汽的流动和扩散。相应地，第二子腔57与第一子腔56相邻，其上方区域不会受到任何遮挡，因此，在一些优选的实施例中，通孔55形成在第二子腔57的顶部。并且，第二侧部处于上述至少两个贯流风扇30的进风区域或出风区域内，以便于从通孔55散发出的水汽在贯流风扇30的作用下送往出风口111。
在这些实施例中，轴承座51和风道分隔件52形成了相对封闭的空间。储水腔形成在轴承座51和风道分隔件52的侧壁之间。具体地，风道分隔件 52的侧壁包括与辅助加热器40相对的第一侧壁521和与第一侧壁521相邻的第二侧壁522。第一子腔56形成在轴承座51与风道分隔件52的第一侧壁521之间，第二子腔57形成在轴承座51与风道分隔件52的第二侧壁522之间。
在本发明的一些实施例中，上述至少两个贯流风扇30处于换热器20的前侧，辅助加热器40位于换热器20和上述至少两个贯流风扇30之间，以对经换热器20换热后的空气进行辅助加热，加热效果更佳。具体地，换热器20优选为竖向延伸且开口朝前的“U”型换热器，贯流风扇30位于换热器20的前方内侧，或者说两个贯流风扇被“U”型换热器三面包围，以在贯流风扇的运行时，使其三面吸风均经过换热器20，提升了换热器20的空气流通量，进而提升了其换热效率。
在一些替代性的实施例中，换热器20也可为平板状的换热器。
本领域技术人员应理解，本发明实施例中所称的“上”、“下”、“内”、“外”、“横”、“前”、“后”等用于表示方位或位置关系的用语是以立式空调室内机1的实际使用状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或部件必须具有特定的方位，因此不能理解为对本发明的限制。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
