Description

导风装置和空调器 技术领域 本发明涉及空调领域, 更具体地, 涉及一种导风装置和空调器。 背景技术 空调器出风口会设置双向导风装置, 通过叶片的方向控制送风范围, 以便实现空 调器扫风。 为了方便操作, 一部分空调器会设置手动导风装置, 人工拨动叶片以控制 空调器的送风范围, 该导风装置的叶片会有定位结构, 以使叶片固定在设定位置不会 自行转动。 现有技术中的定位结构包括设置在出风口处的锯齿形卡口和与叶片连接卡头, 卡 头卡接在卡口中, 这种定位结构体积大、 操作不便, 锯齿形的卡口具有波峰和波谷, 当卡头运动到波峰时, 受力方向会发生突变, 从而坠向波谷并与卡口发生碰撞, 这样 会使拨动叶片时的阻力变大、 噪声变大, 并且容易造成卡头和卡口的损坏, 缩短定位 结构的使用寿命短。 发明内容 本发明旨在提供一种导风装置和空调器, 以解决现有技术的导风装置中的定位结 构不方便操作, 噪声大的问题。 为解决上述技术问题, 根据本发明的一个方面, 提供了一种导风装置, 包括: 安 装板; 多个叶片, 相间隔地设置在安装板上, 多个叶片与安装板可枢转地连接; 连杆, 包括本体和设置在本体上的导向凸块, 本体与多个叶片可枢转地连接; 导向板, 导向 板上开设有弧形的限位开口, 导向凸块的一部分夹紧于限位开口中, 限位开口与导向 凸块相接触的边缘呈平滑变形的曲面。 进一步地, 导向凸块的直径比限位开口的宽度大 0.2mm至 0.4mm。 进一步地, 导向凸块设置在本体的一端。 进一步地, 导向板还包括用于辅助限位开口扩张的第一辅助开口, 第一辅助开口 设置在限位开口的一侧。 进一步地, 导向板还包括用于辅助限位开口扩张的第二辅助开口, 第二辅助开口 设置在限位开口的另一侧。 进一步地, 第一辅助开口和第二辅助开口具有与限位开口相同的曲率, 第一辅助 开口与限位开口的中部相对应地设置, 第二辅助开口与限位开口的两端部相对应地设 置。 进一步地, 第一辅助开口的两端与每个第二辅助开口在限位开口的延伸方向上部 分重叠。 进一步地, 导向凸块包括杆体和位于杆体的端部的凸缘, 凸缘的直径大于杆体的 直径, 凸缘穿过限位开口。 进一步地, 凸缘上沿导向凸块的轴向开设有凹槽。 进一步地, 凹槽延伸至杆体的远离凸缘的一端。 根据本发明的另一个方面, 还提供了一种空调器, 包括机身, 机身上设置有出风 口, 空调器还包括上述的导风装置, 导风装置设置在出风口处, 导风装置的安装板与 机身连接。 本发明的导风装置的多个叶片由连杆连接起来, 叶片随着连杆的移动而转动, 所 以人员可以通过移动连杆而调节风向, 连杆上的导向凸块由限位开口定位, 限位开口 与导向凸块相接触的边缘呈平滑变形的曲面, 使得导向凸块在限位开口中运动时所受 到的力的大小和方向不会发生突变, 导向凸块能够在外力的作用下平稳地在限位开口 中运动, 这使得移动连杆时导向凸块与限位开口之间平滑地摩擦, 相比在锯齿形的定 位结构中移动卡头的阻力更小, 导向凸块更容易滑动, 又因为导向凸块滑动时不会突 然撞向限位开口, 所以滑动的噪声更小。 附图说明 构成本申请的一部分的附图用来提供对本发明的进一步理解, 本发明的示意性实 施例及其说明用于解释本发明, 并不构成对本发明的不当限定。 在附图中: 图 1示意性示出了本发明中的空调器的出风口处的示意图; 图 2示意性示出了本发明中的导风装置的局部示意图; 图 3示意性示出了本发明中的导风装置的凸块部分的示意图。 图中附图标记: 10、 安装板; 20、 叶片; 30、 连杆; 31、 本体; 32、 凸块; 33、 把手; 40、 导向板; 41、 限位开口; 42、 第一辅助开口; 43、 第二辅助开口; 321、 杆 体; 322、 凸缘; 323、 凹槽; 100、 机身。 具体实施方式 以下结合附图对本发明的实施例进行详细说明, 但是本发明可以由权利要求限定 和覆盖的多种不同方式实施。 根据本发明的一个方面, 提供了一种导风装置, 如图 1至 3所示, 该导风装置包 括: 安装板 10; 多个叶片 20, 设置在安装板 10上; 连杆 30, 包括本体 31和设置在 本体 31上的导向凸块 32, 本体 31与多个叶片 20连接; 导向板 40, 导向板 40上开设 有限位开口 41, 导向凸块 32的一部分设置在限位开口 41中并由限位开口 41定位, 导向凸块 32在外力作用下能够沿限位开口 41的延伸方向在限位开口 41中滑动,限位 开口 41与导向凸块 32相接触的边缘呈平滑变形的曲面。 本发明的导风装置的多个叶片 20由连杆 30连接起来, 叶片 20随着连杆 30的移 动而转动,所以人员可以通过移动连杆 30而调节风向,连杆 30上的导向凸块 32由限 位开口 41定位, 限位开口 41与导向凸块 32相接触的边缘呈平滑变形的曲面,使得导 向凸块 32在限位开口 41中运动时所受到的力的大小和方向不会发生突变, 导向凸块 32能够在外力的作用下平稳地在限位开口 41中运动, 这使得移动连杆 30时导向凸块 32与限位开口 41之间平滑地摩擦, 相比在锯齿形的定位结构中移动卡头的阻力更小, 导向凸块 32更容易滑动, 又因为导向凸块 32滑动时不会突然撞向限位开口 41, 所以 滑动的噪声更小。 优选地, 限位开口 41的形状呈弧形。导向凸块 32能够在弧形的限位开口 41中平 滑的滑动, 导向凸块 32在弧形的限位开口 41中依靠摩擦力实现自锁。 可替换地, 限位开口 41呈波浪形。 这种波浪形的限位开口 41并非现有技术中的 锯齿形, 导向凸块 32在这种波浪形的限位开口中运动时的受力方向均匀地改变,不会 发生如在锯齿形的卡口中运动导致的受力方向突变,这样, 导向凸块 32就能够在外力 的作用下平稳地在限位开口 41中运动, 并且可以更稳定的固定在限位开口 41的波谷 的位置, 相比锯齿形的卡口, 导向凸块 32在波浪形的限位开口 41中能够更平稳的滑 动, 摩擦力较小, 产生的噪声也较弱。 优选地, 导向凸块 32能够自锁在限位开口 41中的任意位置。 现有技术中卡头只 能固定在锯齿形的卡口中的波谷的部分,而本发明的导向凸块 32能够自锁在限位开口 41中的任意位置, 提供了更多样的可选择的送风方向。 优选地, 导向凸块 32的最大外径比限位开口 41的宽度大 0.2mm至 0.8mm。这样 使导向凸块 32平时可以卡紧在限位开口 41中, 实现自锁, 不会随意移动, 保证叶片 20的方向稳定。导向凸块 32的最大外径与限位开口 41的宽度之间的差值是根据导向 板 40的材料决定的,若导向板 40由较容易变形的材料制成,则导向凸块 32的最大外 径与限位开口 41的宽度之间的差值可以较大, 若导向板 40由不易变形的材料制成, 则差值较小。 优选地,导向凸块 32在实际运动过程中与限位开口 41之间具有约 0.3mm的干涉, 以实现自锁, 同时该干涉量不能过大, 否则阻力过大, 不便于导向凸块 32的滑动。 优选地, 如图 1和 2所示, 导向凸块 32设置在本体 31的一端。 导向凸块 32和导 向板 40可以设置在出风口的外侧, 这样可以使出风口更加简洁。 优选地, 连杆 30还包括把手 33, 把手 33设置在本体 31上, 并朝远离叶片 20的 方向延伸。 优选地,导向板 40还包括用于辅助限位开口 41扩张的第一辅助开口 42。优选地, 导向板 40还包括用于辅助限位开口 41扩张的第二辅助开口 43, 第一辅助开口 42设 置在限位开口 41的一侧,第二辅助开口 43设置在限位开口 41的另一侧。 由于导向凸 块 32的直径比限位开口 41的宽度大, 所以导向凸块 32在限位开口 41中运动时导向 凸块 32或限位开口 41会发生形变, 为了使导向凸块 32更方便的在限位开口 41中运 动, 本发明在导向板 40上开设辅助开口, 以辅助限位开口 41形变扩张。 优选地, 如图 2所示, 限位开口 41呈弧形, 第一辅助开口 42和第二辅助开口 43 具有与限位开口 41相同的曲率。若限位开口 41呈波浪形,则第一辅助开口 42与第二 辅助开口 43可以呈弧形, 也可以呈与限位开口 41相对应的波浪形。 优选地, 第一辅助开口 42与限位开口 41的中部相对应地设置, 第二辅助开口 43 与限位开口 41的两端部相对应地设置。由于导向凸块 32在限位开口 41中运动时受力 方向不同, 当导向凸块 32运动到限位开口 41的中部时, 限位开口 41向弧形的圆心方 向形变, 所以第一辅助开口 42开设在限位开口 41的靠近圆心的一侧; 当导向凸块 32 运动到限位开口 41的两端时, 限位开口 41需要向远离圆心的一侧形变, 所以第二辅 助开口 43开设在限位开口 41的远离圆心的一侧。 如果仅在一侧开设辅助开口, 则导 向凸块 32在限位开口 41的中部或者端部运动的阻力很大, 不易拨动; 如果同时在两 侧开设与限位开口 41完整对应的辅助开口,则在导向凸块 32在限位开口 41的中部或 者端部运动时的阻力过小, 难以形成自锁。但是, 仅在限位开口 41的一侧开设辅助开 口或在限位开口的两侧开设完整的辅助开口均可以实现辅助限位开口 41变形的效果, 只是如图 2所示的辅助开口是更优的设计。 优选地,第一辅助开口 42的两端与每个第二辅助开口 43在限位开口 41的延伸方 向上部分重叠,第一辅助开口 42与第二辅助开口 43相互重叠 8度到 15度。重合区域 是为了使导向凸块 32在运行到相应位置时限位开口 41的形变更加方便。 优选地, 限位开口 41的圆心半径为 23mm至 27mm。 优选地, 如图 3所示, 导向凸块 32包括杆体 321和位于杆体 321的端部的凸缘
322, 凸缘 322的最大外径大于杆体 321的直径, 凸缘 322穿过限位开口 41。 凸缘 322 可以防止导向凸块 32从限位开口 41中脱落, 从而保证叶片 20不会失控。 优选地, 凸缘 322的远离杆体 321 的一端的直径小于限位开口 41 的宽度。 凸缘 322的一端呈锥形, 这样可以更方便地挤开限位开口 41, 从而将凸缘 322套入限位开 口 41中。 优选地, 凸缘 322上沿导向凸块 32的轴向开设有凹槽 323。 优选地, 凹槽 323延 伸至杆体 321的中部。 在向限位开口 41内安装导向凸块 32时, 要想内挤压凸缘 322, 使凸缘挤过限位开口 41, 所以开设凹槽 323可以帮助凸缘变形, 在穿过限位开口 41 后凸缘 322回弹, 拆卸时也要先向内挤压凸缘 322, 再将凸缘 322从限位开口 41中退 出。 此外, 凹槽 323还可以辅助杆体 321变形, 以便在限位开口 41中运动。 根据本发明的另一个方面, 还提供了一种空调器, 如图 1所示, 该空调器包括机 身 100, 机身 100上设置有出风口, 空调器还包括权利要求上述的导风装置, 导风装 置设置在出风口处, 导风装置的安装板 10与机身 100连接。 采用本申请的导风装置的空调器, 导风装置容易调节, 阻力小、 噪声小, 并且使 用寿命相比现有技术中的锯齿形卡口延长。此外, 如图 1所示, 向凸块 32与 向板 40设置在空调器的出风口的外侧, 不会影响出风口出风, 而且还能够达到出风口整洁 美观的效果。 优选地, 导风装置的安装板 10与机身一体成型。 优选地, 导向板 40与机身一体成型。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
