本申请提出一种暖风机控制方法，易于理解的是，该方法用于暖风机的取暖控制。
在本申请实施例中，如图1所示，该暖风机控制方法，包括
S100、按照预设周期对环境温度进行采样；
S200、将采样得到的温度值与预设温度值进行比较得到温度控制信号；
S300、根据温度控制信号调整发热体功率及风机转速。
需要说明的是，在暖风机中安装有风机和发热体。本实施例中该发热体采用正温度系数加热片。采样温度通过热敏电阻实现，该热敏电阻设置于暖风机的进风口。其中，发热体用于加热空气，风机则用于加快热体产生的热空气的对流，使得室内温度分布均匀，加快温升。
在步骤S200中，通过将温度值与预设温度值进行比较，可判断环境温度的高低。在本实施中，发热体具有两个功率档位，风机也具有两个转速档位。易于理解的是，为进一步提高控制精度，可增加发热体的工作档位的数量以及风机工作档位的数量。
在环境温度较低时，控制发热体工作在大功率档位，并控制风机运行于高转速档位，随着环境温度的逐渐上升，可调整发热体和风机的工作档位，通过两者配合，快速制暖，并实现恒温控制。
本申请技术方案通过检测环境的温度值，与预设的温度值进行比较，得温度控制信号，根据该温度控制信号同时调节的风机转速及发热体功率，加快温升速率，能够更精准的实现恒温控制，从而降低取暖操控频率，提升控制性能。
具体地，所述“将采样得到的温度值与预设温度值进行比较得到温度控制信号”包括：
将采样得到的温度值与预设温度值进行作差，将作差得到的差值转换形成温度控制信号。
本实施例中，是采用作差的方法进行比较，以判断环境温度的高低。除此之外，还可采用其他比较的方法进行判断，例如将采样的温度值与预设温度值相除，通过相除后得到的商来判断。
具体地，所述“根据温度控制信号调整发热体功率及风机转速”包括：
当预设温度值减去采样得到的温度值的差值大于第一预设差值时，控制风机按照高档转速进行转动和控制发热体按照高档功率进行加热。
本实施例中，所述第一预设差值为5摄氏度，所述高档转速的范围为1800~2300转/分钟，所述高档功率的范围为1800~2200瓦。需要说明的是，当预设温度值减去采样到的温度值的差值大于5摄氏度时，表明环境温度较低，急需制热，此时暖风机的风机工作于高功率档位，发热体也工作于高功率档位。
具体地，所述“根据温度控制信号调整发热体功率及风机转速”包括：
当预设温度值减去采样得到的温度值的差值处于第一预设差值和第二预设差值之间时，控制风机按照高档转速进行转动和控制发热体按照低档功率进行加热。
本实施例中，所述第一预设差值为5摄氏度，第二预设差值为3摄氏度，所述低档转速的范围为900~1600转/分钟，所述高档功率的范围为1800~2200瓦。当比较的差值处于3摄氏度~5摄氏度之间时，表明环境温度升高，环境舒适度得到提升，此时适当降低风机转速，使风机转速工作于低档转速，降低风机噪音，减小对人的不良干扰。
具体地，所述“根据温度控制信号调整发热体功率及风机转速”包括：
当预设温度值减去采样得到的温度值的差值小于第二预设差值且大于零时，控制风机按照低档转速进行转动和控制发热体按照低档功率进行加热。
本实施例中，第二预设差值为3摄氏度，所述低档转速的范围为900~1600转/分钟，所述低档功率的范围为900瓦~1600瓦。当比较的差值处于3摄氏度以内时，表明环境温度已经接近预设温度值，无需进行快速制热，需要进行微调温度，此时降低发热体的加热功率，使发热体工作于低档功率使风机转速工作于低档转速，降低能耗，并提高了恒温控制能力。
具体地，所述“根据温度控制信号调整发热体功率及风机转速”包括：
在采样的温度值达到预设温度值时，控制风机停止工作，延时预设时间后再控制发热体停止工作。
需要说明的是，风机转动时，会产生振动的噪音，在采样的温度值达到预设温度值后，先关断风机电源，使风机停止工作，以降低噪音。
