Description

一种吊顶式新风空调室内机 技术领域
本发明涉及家用电器领域，具体地说，涉及一种新风机。
 背景技术
普通中央空调盘管机，宽度一般在500mm左右，高度一般在300mm左右，需要相对较宽较高（宽度一般大于600mm，高度一般大于400mm）的直线吊顶来安装，影响吊顶美观度；在对室内空气进行温湿度调控时，需要相对封闭的室内环境，室内空气无法与室外空气进行循环交换，导致室内氧气含量不断下降，二氧化碳含量不断升高，长期待在这种环境里对身体健康有害。
现有的新风机虽然可以实现室内外空气的循环流通，但是无法对空气的温湿度进行有效调控。
而目前市面上虽然有几款带新风功能的空调，但是产品外形、安装方式与传统壁挂式或落地式空调相同，占用室内空间。由于不是隐蔽安装，导致设备本体、新风管道、铜管等可见，影响室内美观度。另外，这种产品仅设有净化效率低下的过滤网，无法对室内空气进行高效过滤，起不到净化空气的作用。
例如，实用新型专利申请公开号CN208704096U，公开日2019年4月5日，实用新型的名称为一种吊顶式功能转换的空气清洁器，该申请案公开了一种吊顶式功能转换的空气清洁器，一种吊顶式功能转换的空气清洁器，包括上开口的外壳、顶盖、主体、进风风机、排风风机、室外新风初级过滤网、室内过滤网和功能部件，外壳的室内端设置室内回风接口和新风入室接口、室外端设置有室外新风接口和排风接口；主体包括室外进气口、室外新风初级过滤腔、功能腔、室内过滤腔、进风风机腔、室内新风口、室内回收口、导风道、排风风机腔和排风口；主体嵌入外壳内，顶盖与主体的上开口扣合；其特征在于：所述室内新风口、进风风机腔、排风风机腔和排风口位于主体的一侧，室外进气口、室外新风初级过滤腔、功能腔和室内回收口位于主体的另一侧； 所述室外新风初级过滤网、功能部件和室内过滤网分别与室外新风初级过滤腔、功能腔、室内过滤腔可拆卸连接；维修或更换热时，室外新风初级过滤网、室内过滤网和功能部件从主体和外壳的底部或侧部拆卸。其不足之处是虽然更换或清洁方便且功能转换方便，但是设备体积大，对安装空间要求较高，过滤效率不高。
 技术问题
本发明克服了现有技术中普通中央空调盘管机、新风空调对安装空间要求较高和现有的新风机无法调节温湿度的问题，提出了一种可以调节室内的温湿度的同时将室外富氧的新鲜空气经过过滤净化引入室内，并且设备体积小巧，对安装空间要求较低，可以隐蔽安装在吊顶内的一种吊顶式新风空调室内机。
 技术解决方案
为实现以上目的，本发明通过以下技术方案来实现：
一种吊顶式新风空调室内机，包括壳体、离心风机、换热器、接水盘、过滤网组件、电控盒，所述壳体上设有新风口、回风口、送风口，所述壳体一侧并列设有新风口、回风口，与这一侧相对的另一侧设有送风口；所述壳体内送风口后依次设有离心风机、换热器、过滤网组件，过滤网组件与新风口、回风口之间的腔室上方设有电控盒；所述换热器自所述过滤网组件的上端向送风口方向向下倾斜，所述换热器下方设有接水盘。
依次为送风口、离心风机、换热器、新风回风口的排布的设计，可以达到气流与换热器的接触面积最大化的效果，设备的热交换效率更高。所述换热器自所述过滤网组件的上端向送风口方向向下倾斜，使得从新风口进入的室外新风和回风口进入的室内污风与换热器的接触面积变大，提高了转换效率，倾斜设置也使得在高效率下新风空调室内机的整体高度降低，节省了空间。换热器下方设有接水盘，这样可以有效避免冷凝水在设备内部的渗漏问题。
作为优选，所述换热器的上端与过滤网组件的上端平齐。
作为优选，所述换热器的下端设在送风口下方。
换热器的上端与过滤网组件的上端平齐，换热器的下端设在送风口下方，这样设置使得进入的室外新风和室内污风更全面的经过换热器，提高换热器的交换效率，而且使得换热器各个部位产生的冷凝水都可以随着风吹过顺着换热器向下倾斜的方向汇集在接水盘中，有效避免冷凝水在设备内部的渗漏问题。

 本发明的最佳实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
如图1、图2所示一种吊顶式新风空调室内机，包括壳体6、离心风机5、换热器4、接水盘7、过滤网组件13、电控盒10，所述壳体6上设有新风口21、回风口31、送风口1，所述壳体6一侧并列设有新风口21、回风口31，与这一侧相对的另一侧设有送风口1；所述壳体6内送风口1后依次设有离心风机5、换热器4、过滤网组件13，过滤网组件13与新风口21、回风口31之间的腔室上方设有电控盒10；所述换热器4自所述过滤网组件13的上端向送风口1方向向下倾斜，所述换热器4下方设有接水盘7。
依次为送风口1、离心风机5、换热器4、新风回风口31的排布的设计，可以达到气流与换热器4的接触面积最大化的效果，设备的热交换效率更高。所述换热器4自所述过滤网组件13的上端向送风口1方向向下倾斜，使得从新风口21进入的室外新风和回风口31进入的室内污风与换热器4的接触面积变大，提高了转换效率，倾斜设置也使得在高效率下新风空调室内机的整体高度降低，节省了空间。换热器4下方设有接水盘7，这样可以有效避免冷凝水在设备内部的渗漏问题。
换热器4的上端与过滤网组件13的上端平齐，换热器4的下端设在送风口1下方，这样设置使得进入的室外新风和室内污风更全面的经过换热器4，提高换热器4的交换效率，而且使得换热器4各个部位产生的冷凝水都可以随着风吹过顺着换热器4向下倾斜的方向汇集在接水盘7中。同时换热器4的高压管和低压管从送风口1端面伸出，确保换热器4各个部件产生的冷凝水都能汇集在接水盘7中。而接水盘7连接排水管从送风口1端面伸出，使得接水盘7中的水可以通过排水管排出，有效避免冷凝水在设备内部的渗漏问题。同时换热器4的高压管上设有的电子膨胀阀9实现了新风空调室内机的变频多联功能。
换热器4和所述离心风机5之间设有电加热模块8，所述电加热模块8固定在接水盘7内部。电加热模块8采用PTC电加热技术，PTC是一种半导体发热陶瓷，当外界温度降低，PTC的电阻值随之减小，发热量反而会相应增加。电加热模块8可以在冬季制热工况下实现更高效率的提升室内空气温度。
接水盘7与壳体6之间设有保温消音棉12，保温消音棉12通过送风口1端面和过滤网组件13卡紧固定。接水盘7呈刀型，有矩形主体和一侧长型导水管构成，导水管连接从送风口1端面伸出的排水管。由图4可以看出，宽度方向上被铺设了保温消音棉12的壳体6卡紧；在高度方向上利用铺设了保温消音棉12的壳体6底部和上部的折弯固定；在长度方向上，由图5可以看到，利用铺设了保温消音棉12的壳体6的送风口1端面和过滤网组件13卡紧固定。在过滤网组件13和送风口1之间的壳体6都设有保温消音棉12，在固定方式上没有用到一个金属紧固件与壳体6相连接，这样可以有效降低在制冷制热工况下能量的损耗，避免在制冷或除湿工况下壳体6外表面的结露问题的出现，同时可以有效隔绝噪音源离心风机5产生的噪音，提高产品节能效率，提升产品的舒适性。
所述新风口21、回风口31在壳体6外侧设有电动风阀，新风口21外设新风电动风阀22，回风口31外设回风电动风阀32。电动风阀用来控制新风口21和回风口31的开闭，使得新风空调室内机可以切换不同模式。壳体6外下方设有维护盖板11，有利于新风空调室内机的维修。
新风空调室内机的模式有温湿度调节模式、内循环模式、外循环模式、混风模式。
温湿度调节模式：室内外空气流经换热器4，实现热交换过程，再将处理过温湿度的空气送入室内，实现室内的制冷制热及除湿。在制冷及除湿工况下，换热器4翅片上产生的冷凝水滴落到接水盘7中，通过排水管排至室外。在冬季制热工况下，室内外空气还流经电加热模块8，实现更高效率的提升室内空气温度。
内循环模式：新风电动风阀22闭合，回风电动风阀32开启，室内空气通过回风管道、回风电动风阀32、过滤网组件13、换热器4、离心风机5、送风口1后经由室内送风管道送入室内，此模式下对室内空气进行净化过滤。若在内循环模式下启动温湿度调节模式，则控温、除湿的效率达到最高，可以快速达到用户设定的温湿度。
外循环模式：新风电动风阀22开启，回风电动风阀32闭合，室外空气通过新风管道、新风电动风阀22、过滤网组件13、换热器4、离心风机5、送风口1后经由室内送风管道送入室内。室外富氧的空气经过净化后送到室内，利用微正压原理实现室内外空气的循环流动。
混风模式：新风电动风阀22、回风电动风阀32均开启，室外空气通过新风管道和新风电动风阀22进入电控盒10放置段，室内空气通过回风管道和回风电动风阀32进入电控盒10放置段，之后两种空气混合通过过滤网组件13、换热器4、离心风机5、送风口1再由室内送风管道送入室内。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
