Description

一种食物处理器的循环换风装置 技术领域
本发明涉及家用电器的电机及其散热装置，具体涉及一种食物处理器的循环换风装置。
背景技术
具有搅拌、粉碎等多功能的食物处理器，由于简便快捷的操作使得其受到越来越多的人喜爱，而随着人们生活质量的提高，消费者对此类产品的工作可靠性和噪音等性能要求也越来越高。
现有的食物处理器，为了提高食物的粉碎效果，通常会采用高功率或者高转速的电机，由此，食物处理器工作时，其工作温度也较高，影响工作效率且会降低使用寿命。中国发明专利申请CN 101172023 B公开了一种“用于混合食品的搅拌机”，电机支架14包围在电机16外，电机支架14上还设有风扇26，搅拌机10和风扇26均由电机16驱动。风扇26运转后能将电机16周围的空气与外界冷风进行置换，使电机16保持正常工作温度，但是仍存在以下问题：
1.电机16的负载增大，运行的高效性降低；
2.由于电机16的转速较高，带动风扇16后，食物处理器的振动频率更高，并产生更大的噪音；
3.风扇26与电机16保持相同转速，无法自行调节转速：风扇26的自身转速能达到换风效果即可，转速过高会造成资源浪费；若搅拌机内的食材较硬，会使得搅拌机10无法转动，导致电机无法正常运行，风扇也就无法运行，此时食物处理器极易损坏。
由此可见，目前的食物处理器具有振动和噪音较大、风扇无法独立调 节转速的问题。
发明内容
本发明所要解决的技术问题是目前的食物处理器具有振动和噪音较大、风扇无法独立调节转速的问题。
为了解决上述技术问题，本发明所采用的技术方案是提供了一种食物处理器的循环换风装置,包括：

本发明，将驱动食物处理器的搅拌或粉碎组件运转的电机和用于排风的风扇分别独立设置，降低了电机的负载，可减少食物处理器的振动，同时降低噪音；风扇驱动自身运转，可根据换风需要独立调节其转速，使转速维持在保证换风效果的合理范围，避免资源浪费，不受电机运行状态的影响，在电机运转出问题时也能有效为其降温，保持良好的散热效率，从而延长食物处理器的使用寿命。
在上述一种食物处理器的循环换风装置中，所述机座的中部设有上下敞口的电机罩壳，所述电机通过电机支架固定在所述电机罩壳内。这种结构设置，可减少由于电机振动而引起机座或机身的振动。
