Description

一种电机冷却机构及洗地机 技术领域
本发明属于清洁设备技术领域，具体涉及一种电机冷却机构及洗地机。
背景技术
洗地机是一种适用于硬质地面清洗同时吸干污水，并将污水带离现场的清洁机械，洗地机集吸尘吸水功能于一体，具有环保、节能、高效等优点，洗地机的工作原理是在清扫过程中，滚刷驱动电机带动滚刷旋转，滚刷转动清扫，同时通过吸力电机将污水、灰尘、杂物等吸入污水箱内，使用过程中，由于滚刷驱动电机的持续高负载工作，常会出现发热现象，为了提高滚刷驱动电机的使用寿命，需要采取必要的措施对滚刷驱动电机冷却、散热。
现有技术中，滚刷驱动电机的散热冷却方式常见的有两种：1.将滚刷驱动电机置于一个较大的空间内，依靠空气自然对流进行散热，这样的冷却方式不能将滚刷驱动电机产生的热量及时排走，还会对洗地机的其他零部件产生影响，会减小整个产品的质量及使用寿命；2.从吸力电机处直接引入一条吸气管，通过吸气管将滚刷驱动电机产生的热量抽走，由于吸力电机与滚刷驱动电机的距离较远，这种冷却方式要求连接管道很长，装配麻烦，费时费力且增加了产品的成本。
发明内容
本发明的目的在于提供一种电机冷却机构及洗地机，以解决现有技术中滚刷驱动电机冷却管道过长、散热效率不高的技术问题。本发明解决其技术问题所使用的技术方案是：
一种电机冷却机构，应用于滚刷驱动电机的散热，包括：
吸气管，所述吸气管的一端与待散热空间连通，用于将待散热空间的热量排出；
吸收通道，所述吸收通道具有吸风口，所述吸风口与所述吸气管的另一端连接；
所述吸收通道在外部吸力的作用下，将待散热空间内的空气抽出，通过所述吸风口输送至吸收通道后排出。
本发明进一步的技术方案还包括：所述待散热空间由固定槽和电机盖围合而成，所述待散热空间呈相对密封状态，用于容纳滚刷驱动电机。
进一步地，所述固定槽固定在底座的上表面，所述底座上安装有滚刷。
进一步地，所述滚刷驱动电机通过电机盖封装，所述电机盖具有出气口，所述出气口与吸气管连通。
进一步地，所述电机盖是可拆卸的。
本发明还提供一种洗地机，包括主机组件、手柄组件以及滚刷，关键是还包括前述任一项所述的电机冷却机构。
进一步地，所述主机组件包括清水箱、污水箱、吸力电机、电源组件和控制系统，所述手柄组件上设置有自清洗按键，所述自清洗按键与控制系统电连接。
进一步地，所述滚刷具有保护壳，所述保护壳通过卡扣固定在底座上。
与现有技术相比，本发明的有益技术效果为：本发明通过在吸收通道上开设吸风口，吸风口通过吸气管与待散热空间连通，由于滚刷驱动电机所处的待散热空间位于底座上方，吸收通道的底部也位于底座上，因此吸气管的长度可以做到很短，装配十分简单，大大节约了管道的成本；在吸力电机的吸力作用下，待散热空间的热量可以快速排出，散热效率更高。

待散热空间3由固定槽6和电机盖7围合而成，所述待散热空间3呈相对密封状态，用于容纳滚刷驱动电机1，具体地，固定槽6呈两侧平行、中间下凹的弧面，以便于滚刷驱动电机1的固定、安装；待散热空间3具有一定的透气度，目的是为了增加待散热空间3内外空气的对流速度，提高散热效率。

使用时，用户按下自清洗按键14开机，控制系统控制滚刷9旋转，同时清水箱喷出清水，滚刷9开始清洁地面，吸力电机12启动后产生吸力，在吸收污水、灰尘、杂物等的同时，也通过吸收通道4将滚刷驱动电机1所产生的热量吸走，从而达到对滚刷驱动电机1散热的目的。
电源组件13用于给滚刷驱动电机1提供电源，电源组件13可以是蓄电池组，也可以是可充电电池，例如可充电锂离子电池，这里不作限制。
滚刷9优选具有保护壳15，保护壳15通过卡扣16固定在底座8上，保护壳15在起到保护滚刷9作用的同时，也更加方便污水、灰尘、杂物等的收集，有效的提高了清洁效率。
本发明通过在吸收通道上开设吸风口，吸风口通过吸气管与待散热空间连通，由于滚刷驱动电机所处的待散热空间位于底座上方，吸收通道的底部也位于底座 上，因此吸气管的长度可以做到很短，装配十分简单，大大节约了管道的成本；在吸力电机的吸力作用下，待散热空间的热量可以快速排出，散热效率更高。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不可以理解为对发明保护范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明的保护范围应以所附权利要求为准。
