下面参考图 1 -图 1 1描述根据本发明实施例的一种空调室内机, 该空调室内机可为 吊顶式室内机, 例如通过连接件吊装至房间顶部的空调室内机, 可显露在天花板下方、 嵌入天花板中, 或半嵌入天花板中。
如图 1所示, 根据本发明实施例的空调室内机, 包括: 壳体 1、 换热器 2、 风扇 3 和面板 4。 壳体 1 内限定有容纳腔室 10 , 容纳腔室 10的底部形成有间隔开的进风口 1 1 和出风口 12。
换热器 2设在容纳腔室 10内且邻近进风口 1 1设置以将从进风口 1 1进入容纳腔室 10内的回风换热。 风扇 3设在容纳腔室 10内, 风扇 3带动气流从进风口 1 1进入容纳 腔室 10内, 气流 1 1经过换热器 2和风扇 3后从出风口 12送出。
面板 4设在壳体 1 的底部, 面板 4构造成适于在同时关闭进风口 1 1和出风口 12 的关闭位置和同时打开进风口 1 1和出风口 12的打开位置之间可移动, 且在打开位置 时, 面板 4至少部分地将进入进风口 1 1的空气与从出风口 12离开的空气分隔开。
由此, 也就是说, 当空调室内机不工作时, 面板 4位于关闭位置, 此时进风口 1 1 和出风口 12由面板 4关闭, 使得外观美观, 且可防止灰尘进入容纳腔室内。 而当空调 室内机工作时, 面板 4移动到打开位置, 此时进风口 1 1和出风口 12之间至少通过面 板 4隔开, 换言之, 出风口 12送出的风将不会轻易地被进风口 1 1直接吸入而造成送 风短路的情形。
根据本发明实施例的空调室内机,通过采用在关闭位置和打开位置之间可移动的面 板, 使得在不工作时进风口和出风口被遮蔽以美观且防止了灰尘的进入, 另外, 在工 作时, 可防止从出风口送出的冷风或热风回流和短路, 保证制冷或制热量不会损失, 送风 效果更好。
在本发明的以上及以下描述中, 均以壳体内具有一个容纳腔室为例对空调室内机进行 描述。 然而, 本发明并不限于此, 在本发明的一个可选实施例中, 壳体内还可设有两个对 称的容纳腔室、 两个换热器、 两个风扇及至少两个面板, 如图 1 1所示, 其中每个容纳 腔室的底部均形成有间隔开的进风口和出风口, 两个换热器分别设在两个容纳腔室内, 两个风扇也分别设在两个容纳腔室内, 至少两个面板对称地分布在壳体的底部, 且分 别在同时关闭进风口和出风口的关闭位置和同时打开进风口和出风口的打开位置之间 可移动。
在本发明的一些实施例中, 容纳腔室 10的出风口 12为一个, 且面板 4为一个, 且 面板 4从关闭位置向进风口 1 1一侧平移至间隔位置、 并转动至打开位置, 其中面板 4 位于间隔位置时, 面板 4的一端止抵在进风口 1 1和出风口 12之间的间隔部 9下表面 上, 如图 1和图 2、 图 6-图 10中所示。 本领域内技术人员可以理解, 本发明并不限于 此, 例如出风口可为两个或两个以上, 且对应的面板也可为两个或两个以上。 在本发明的 另一些实施例中,容纳腔室 10的出风口为多个且分别分布在壳体 1底部的至少两端上, 面板为多个且——对应地设在相应的出风口与进风口之间的底部 (图未示出) , 且多 个面板 4 均位于关闭位置时同时关闭进风口和多个出风口, 多个面板均位于打开位置 时同时打开进风口和多个出风口。
下面的描述中均以进风口和出风口均为一个、 且对应的面板为一个为例进行说明, 具体地, 面板 4在从关闭位置到打开位置移动的过程, 包括从关闭位置到间隔位置的 平移、 及从间隔位置到打开位置的转动。 其中面板 4从关闭位置 (如图 1所示) 向进 风口 11一侧平移至间隔位置 (图未示出) 、 并转动至打开位置, 其中面板 4位于间隔 位置时, 面板 4的一端位于进风口 11和出风口 12之间的间隔部 9下方。
根据本发明的一些实施例, 面板 4位于打开位置时, 面板 4的一端止抵位于进风口
11和出风口 12之间的间隔部 9, 且另一端向下倾斜延伸, 其中面板 4所在平面与壳体 1底面所在水平面之间的角度 α的范围为: 15~150度。 面板 4从关闭位置平移到间隔位 置的过程中, 面板 4沿出风口 12到进风口 1 1的方向移动, 在移动到间隔位置后, 即 面板 4的一端止抵间隔部 9下表面后, 远离间隔部 9的一端向远离进风口 11的方向转 动。 如图 1-11所示的示例中, 进风口 11位于壳体 1的底部右侧, 而出风口 12位于壳 体 1 的底部左侧, 此时, 面板 4的移动过程包括从左向右的平移、 以及左端抵在间隔 部 9的底部且右端顺时针旋转。
由此, 当面板 4移动到打开位置时, 进风口 11和出风口 12被面板 4分隔, 气流从 面板 4的展开角度抽入进风口 11 , 吹风时, 面板 4顶靠于进风口 11和出风口 12分隔 处, 挡住了从出风口 12送出的空气直接回流到进风口 1 1的气流, 由于面板 4挡住了 送出空气的扩散, 会沿着面板 4形成流速较高的气流, 有利于在面板 4方向上送更远 的距离。 即使面板 4 另一侧处有送风进入进风口一侧, 由于距离较远, 且与周边空气 的混合, 所以并不会改变进风口 11的空气温度, 不影响吹风效果, 还可以防止新吹出 的冷风或热风被相邻的进风口 11吸回, 防止冷风或热风回流短路, 保证制冷或制热量 不会损失。
为了更清楚地描述, 如图 3中的坐标系所示, X轴为水平方向, Υ轴为竖直方向, 两轴相交于 0 , 则 O A、 OB和 OC分别为三个面板 4展开的方向, 其中, 坐标原点 0 为面板 4与间隔部 9下表面的相交点, 且以 X轴的方向为零度, 顺时针转动为正值, 则三者分别是 α 1 角为 Z XO A =15度; α 2 角为 ZXOB=90度; α 3 角为 ZXOC=140 度。 在面板 4与水平方向的夹角 α的取值范围为 15度 < α < 150度。
另外, 采用不同的 α角除了上面提到的技术效果外, 改变 α角的还会产生一些新的 技术效果。 如需要扩大送风范围, 连带进风口 11侧的空间也需要降温时, 则通过改变 α角, 可把冷空气送到最大的范围, 同时由于面板 4阻隔, 也会加大面板 4侧的送风 速度和送风距离, 提高用户的舒适性。 如需要为特定方向送风时, 例如只有在出风口 12—侧的远处有制冷需求, 则 α角可选地采用 140度, 这样可以集中所有的送风吹向 出风口 12—侧的远处, 使得送风速度和送风距离非常远, 有非常好的降温效果, 同时 不会对其他的地方送风, 提高了空调的利用效果。
可选地, 空调在制热运行时, 面板 4位于打开位置时与壳体 1底面所在水平面之间 的角度 α的范围为: 40~140度。 可选地, 空调在小风量运行时, 面板 4位于打开位置时 与壳体 1底面所在水平面之间的角度 α的范围为: 15~75度。
在本发明的一些实施例中, 面板 4构造成可在角度 α的范围内摆动。 也就是说, 面 板 4位于打开位置时, 面板 4作为导风部件, 其与壳体 1底面所在水平面之间的角度 α是变化的, 且在上述角度 α的范围内不停摆动, 以不断调整送风角度和送风范围。 当然, 本发明并不限于此, 在本发明的另一些实施例中, 当面板 4位于打开位置时, 面板 4停止在 α为预定角度值的位置处。 也就是说, 空调器室内机开启时, 面板 2展 开到一定的角度, 并保持该角度。
可选地, 根据本发明进一步实施例的空调室内机还包括导风板 5 , 导风板 5可摆动 地设在出风口 12处, 用于导流从出风口 12离开的空气的方向。 当面板 4位于打开位 置时, 导风板 5与面板 4配合以实现更多范围内的导风效果。
具体地, 空调室内机还包括驱动装置, 驱动装置设在面板 4和壳体 1之间, 以驱动 面板 4在关闭位置和打开位置之间移动。
下面参考图 1 -图 1 1通过多个实施例对根据本发明的空调室内机以及面板的驱动装 置进行详细描述。 其中以进风口 1 1位于壳体 1的底部右侧而出风口 12位于壳体 1的 底部左侧为例进行说明。 实施例一
如图 1和图 2所示, 壳体 1 内限定有容纳腔室 10 , 容纳腔室 10的底部形成有间隔 开的进风口 1 1和出风口 12 , 在进风口 1 1和出风口 12之间设有间隔部 9。 换热器 2和 风扇 3设在容纳腔室 10内。 面板 4设在壳体 1的底部且在关闭位置和打开位置之间移 动。
参考图 2 , 当面板 4位于打开位置时, 面板 4停止在 α为预定角度值的位置处。 具 体地, 面板 4的左端抵近出风口 12和进风口 1 1之间的间隔部 9 , 右端向右下方斜伸出 并保持一定角度, 其中水平方向与壳体 1 底面所在水平面之间的夹角 α的范围为 15~150度。 也就是说, 面板 2展开到一定的角度 α , 并保持该角度, 该角度 α的范围 为 15~150度。 在图 2中示出的实施例中, 该角度 α为 60度。
在本实施例中, 驱动装置包括第一驱动组件 6和第二驱动组件 7 , 第一驱动组件 6 设在面板 4和壳体 1之间以驱动面板 4平移至预定位置, 即上述间隔位置。 第二驱动 组件 7设在面板 4和壳体 1之间以驱动面板 4顺时针转动。
在本发明实施例的一个示例中, 如图 4所示, 第一驱动组件包括第一齿条 61和第 一齿轮 62 , 其中第一齿条 61设在面板 4上, 第一齿轮 62设在壳体 1上、 且通过第一 齿条 61与第一齿轮 62的啮合而使面板 4相对于壳体 1平移。 在本发明实施例的另一 个示例中, 第一驱动组件包括主动皮带轮和皮带(图未示出) , 主动皮带轮设在壳体 1 上, 皮带与主动皮带轮配合以带动面板 4相对于壳体 1平移。
在本发明实施例的一个示例中, 第二驱动组件包括弧形齿条 71和第二齿轮 72 , 其 中弧形齿条 71设在面板 4上, 第二齿轮 72设在壳体 1上、 且第二齿轮 72与弧形齿条 71啮合, 以使面板 4相对于壳体 1转动, 如图 5所示。 在本实施例的另一个示例中, 第二驱动组件包括主动齿轮和齿轮组 (图未示出) , 其中主动齿轮设在壳体 1 上, 齿 轮组设在面板 4上且与主动齿轮啮合以带动面板 4相对于壳体 1转动。
其中,值得注意的是, 上述多个示例的第一驱动组件和第二驱动组件可各自组合使 用, 并不拘泥于图中所示的实施例的组合。
根据本发明实施例的空调室内机, 通过采用第一和第二驱动组件, 以有效且快速地 实现面板的平移和展开角度, 结构筒单。
其中, 在本发明实施例的一些示例中, 第一驱动组件 6先驱动面板 4平移至所述间 隔位置时, 第二驱动组件 7再驱动面板 4转动至打开位置并摆动。 当然, 本发明并不 限于此, 在本发明实施例的另一些示例中, 第一驱动组件 6驱动面板 4平移的同时, 第二驱动组件 7驱动面板 4转动。 实施例二
如图 6和图 7所示, 本实施例二与上述的实施例一的结构大致相同, 其中相同的部 件采用相同的附图标记, 不同之处在于: 第一, 在出风口 12处设有可摆动的导风板 5 , 导风板 5与面板 4配合以调整送风方向。 第二, 当面板 4位于打开位置时, 角度 α的 范围内摆动。 具体地, 参考图 6和图 7 , 当面板 4位于打开位置时, 面板 4的左端抵近 出风口 12和进风口 1 1之间的间隔部 9 , 右端向右下方斜伸出并摆动, 其中水平方向与 壳体 1底面所在水平面之间的夹角 α的范围为 15~150度。也就是说, 面板 4在 15~150 度的角度范围内不停摆动, 以不断调整送风角度和送风范围。
在本发明实施例的一个示例中, 如图 7所示, 导风板 6向右侧送风, 且面板 4也向 右侧展开且角度 α为大约 60度。 导风板 6指向送风的方向与水平方向的夹角与面板 4 的夹角 a相同或者近似, 有利于把出风口 12排出的冷空气排向右侧。 而在另一个示例 中, 如图 8所示, 面板 4的 a角为大约 120度, 导风板 6也向左侧送风且和面板 4配 合, 以把出风口 12排出的冷空气排向左侧。
在导风板 6和面板 4配合送风情况下, 面板 4采用的夹角 a的取值范围为 40度 < a < 140度, 在该范围内, 导风板 6和面板 4配合可以实现大的送风范围, 同时可以确保 有面板 4挡住了送出空气的扩散, 会沿着面板 4形成流速较高的气流, 提高了送风和 引流的效果, 有利于在面板 4方向上送出更远的距离。
用于驱动面板 4的驱动装置与与上述实施例一中类似, 在此不再赘述。 实施例三,
如图 8和图 9所示, 本实施例三与上述的实施例二的结构大致相同, 其中相同的部 件采用相同的附图标记, 不同之处在于: 参考图 8和图 9 , 当面板 4位于打开位置时, 面板 4停止在 α为预定角度值的位置处。 在图 8和图 9示出的实施例中, 该角度 α为 90度, 即面板 4引导出风口 12送出的风垂直向下。
出风口 12处设置的导风板 5与面板 4配合以调整送风方向。 如图 8所示, 导风板 5向下侧送风, 面板 4打开到固定角度 90度。 图 9所示, 导风板 5向左侧送风, 面板 4打开到固定角度 90度。
此种设置的实施例多用于制热工况中, 由于需要把热空气送到房间的底处, 提高人 所在的地方的舒适性, 所以, 要更加依靠面板 4 的引流作用, 能够取得较好的向下输 送热空气的作用的面板 4的角度 α取值范围为 75度 < a < 120度, 在该范围内, 配合风 板 5的摆动, 可以实现热空气送到人所在的区域。
用于驱动面板 4的驱动装置与与上述实施例一中类似, 在此不再赘述。 实施例四
如图 10所示, 参考结合图 1 1 , 本实施例四与上述的实施例一的结构大致相同, 其 中相同的部件采用相同的附图标记, 不同之处在于驱动装置的结构。
在本实施例中, 驱动装置包括导板 81和滑块 82 , 其中导板 81连接在面板 4上, 导板 81上具有弧形滑道 81 1 ,滑块 82设在壳体 1上且可在弧形滑道 81 1 内滑动以限定 导板 81的运动轨迹并带动面板 4在关闭位置和打开位置之间移动。
进一步地, 参考图 1 1所示, 在导板 81的外侧边缘上形成有外齿圏 812 , 且驱动装 置进一步包括驱动齿轮 83 , 驱动齿轮 83设在壳体 1上以与外齿圏 812啮合。 其中, 面 板 4通过滑块 82与弧形滑道 81 1的配合、 以及驱动齿轮 83与外齿圏 812的配合在关 闭位置和打开位置之间移动。 当开启空调时, 驱动齿轮 83驱动导向板 81 向下展开, 从而带动面板 4向下展开。 当关闭室内机时, 驱动齿轮 83反向转动, 使导向板 81收 回, 使面板 4遮蔽进风口 1 1和出风口 12。
根据本发明实施例的驱动装置, 筒单实用, 动作可靠, 可以实现面板打开到一定的 角度。
在本实施例中, 空调器室内机运行模式为小风量运行, 在小风量运行模式下, 由于 进风口和出风口的风速均较低, 所以为了进一步降低送风噪音, 同时满足较大的送风 区域, 所以在该模式情况下, 面板角度 a取值范围为 75度 <a < 15度。 这样可以满足小 风量, 低噪音的用户需求。 实施例五 如图 1 1所示, 本实施例五与上述的实施例四中相同的部件采用相同的附图标记, 不同之处仅在于, 实施例五为实施例五为实施例四在出风口一侧镜像对称组合后的空 调器室内机, 即左右两侧分别是轴对称的两个如实施例四中所示的空调室内机。
也就是说, 在壳体内设有两个对称的容纳腔室 10、 两个换热器 2、 两个风扇 3及两 个面板 4 , 如图 1 1所示, 其中每个容纳腔室 10的底部均形成有间隔开的进风口 1 1和 出风口 12 , 两个换热器 2分别设在两个容纳腔室 10内, 两个风扇 3也分别设在两个容 纳腔室 10 内, 两个面板 4对称地分布在壳体 1 的底部, 且分别在同时关闭进风口 1 1 和出风口 12的关闭位置和同时打开进风口 1 1和出风口 12的打开位置之间可移动。 其 中, 两个面板 4分别通过两组实施例四中描述的驱动装置移动。
如图 1 1所示, 当开启空调时, 两边的驱动齿轮 83分别驱动相应的导向板 81向下 展开, 同时滑块 82在相应的弧形滑道 81 1 内滑动以使得对应的面板 4转动, 以使两个 面板 4分别开启到一定的角度 α , 且两个面板 4的相对一端分别止抵到进风口 1 1和出 风口之间的间隔部 9上。
与实施例四类似, 在本实施例五中, 空调器室内机运行模式为小风量运行, 在小风 量运行模式下, 由于进风口和出风口的风速均较低, 所以为了进一步降低送风噪音, 同时满足较大的送风区域, 所以在该模式情况下, 面板角度 a取值范围为 75度 <a < 15 度。 这样可以满足小风量, 低噪音的用户需求。
根据本发明的空调室内机, 通过采用驱动装置驱动面板 4 , 使得面板 4可以在出风 口 12和进风口 1 1之间的间隔部 9处以一定角度展开。 本发明具有以下优点: 第一, 通过面板遮蔽进风口和出风口, 使其在不使用时达到美观, 减少灰尘进入室内机内部; 第二, 可防止冷风或热风回流和短路, 保证制冷或制热量不会损失; 第三, 可配合导 风板实现更有效的送风; 第四, 还可提高制热工况向下送风的速度和静压。
空调室内机各种运行模式, 例如制冷模式、 制热模式以及小风量运行模式, 对本领 域内普通技术人员已熟知, 在此不再详细描述。 另外, 根据本发明实施例的空调室内机 的其他构成例如换热器和风扇等以及操作对于本领域普通技术人员而言都是已知的, 这里 也不再详细描述。
在本说明书的描述中, 参考术语 "一个实施例"、 "一些实施例"、 "示意性实施例"、 "示 例"、 "具体示例"、 或 "一些示例" 等的描述意指结合该实施例或示例描述的具体特征、 结 构、 材料或者特点包含于本发明的至少一个实施例或示例中。 在本说明书中, 对上述术语 的示意性表述不一定指的是相同的实施例或示例。 而且, 描述的具体特征、 结构、 材料或 者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例, 本领域的普通技术人员可以理解: 在不脱 离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、 修改、 替换和变型, 本发明的范围由权利要求及其等同物限定。
