具体实施方式
为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将结合附图对本发明实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
装置实施例
图1是本发明提供的热泵式干衣机的结构示意图。如图1所示，本申请提供的热泵式干衣机包括外侧箱体1、控制系统4以及设置在所述箱体1内的滚筒2，其中，所述滚筒2外侧的箱体1内设置有换气装置3，所述换气装置3可用于干燥所述箱体1与所述滚筒2之间的空气，所述控制系统4与所述换气装置3相连，可用于控制所述换气装置3的开启或关闭。
所述换气装置3可以为换气扇，也可以为风机，其主要通过对箱体1内的空气进行换气来达到驱走箱体1内比较潮湿的空气，使得箱体1内的空气处于干燥的状态。
所以本方案提供的干衣机可给箱体1换气，保持箱体1内部处于干燥状态，防止箱体1内部产生凝露，防止凝露锈蚀箱体1、损坏电器件的情况产生。
于本实施例中，作为优选方案，所述控制系统4位于所述箱体1的内侧，更具体的，所述控制系统4位于所述箱体1门体的上端。当然，所述控制系统4的位置并不局限于此，还可以设置在箱体1内的其它位置。

由于在箱体1内安装的换气装置3也可以起到给压缩机降温的作用，所以该换气装置3可以取代压缩机的散热风扇。该方案在不增加干衣机制造成本，不增加干衣机制造工艺，不增加干衣机制造复杂度的前提下，仅通过改进软件部分即可实现使用一个换气装置3同时达到干燥箱体1内气体及降低压缩机的温度的效果。
于本实施例中，作为优选方案，所述箱体1内设置有用于检测箱体1内温度值的第一温度检测仪，所述第一温度检测仪与所述控制系统4相连，可将所检测到的所述箱体1内温度值传递给所述控制系统4，所述控制系统4将所接收到的温度数据作为参数，进行数据分析，以便所述控制系统4对换气装置3的开启或关闭进行控制。
