The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
本发明提供一种空调器的控制方法，图1是根据本发明一实施例的一种空调器的控制方法的流程图。参见图1并参考图2至图6，本发明实施例的空调器包括壳体、第一风机和第二风机24。壳体的前侧开设有用于吹出换热气流的第一出风口11和用于吹出非换热气流的第二出风口21。第一出风口11和第二出风口21均沿竖直方向延伸，第二出风口21设置于第一出风口11的横向一侧，以使第一出风口11的出风和第二出风口21的出风混合。壳体的周壁上还开设有用于吹出非换热气流的第三出风口31，且第三出风口31位于第一出风口11和第二出风口21的下方。第一风机具有两个出风口，分别与第二出风口21和第三出风口31连通。第二风机24设置于第二出风口21和第一风机的对应的出风口之间。第三出风口和第一风机的对应的出风口之间设置有风门。如图1所示，空调器的控制方法包括：The present invention provides a control method for an air conditioner, and FIG. 1 is a flow chart of a control method for an air conditioner according to an embodiment of the present invention. Referring to FIG. 1 and referring to FIG. 2 to FIG. 6, the air conditioner according to the embodiment of the present invention comprises a housing, a first fan and a second fan 24. A first air outlet 11 for blowing out a heat exchange airflow and a second air outlet 21 for blowing out a non-heat exchange airflow are provided on the front side of the housing. The first air outlet 11 and the second air outlet 21 both extend in the vertical direction, and the second air outlet 21 is arranged on a lateral side of the first air outlet 11 so that the airflow from the first air outlet 11 and the airflow from the second air outlet 21 are mixed. A third air outlet 31 for blowing out a non-heat exchange airflow is also provided on the peripheral wall of the housing, and the third air outlet 31 is located below the first air outlet 11 and the second air outlet 21. The first fan has two air outlets, which are respectively connected to the second air outlet 21 and the third air outlet 31. The second fan 24 is arranged between the second air outlet 21 and the corresponding air outlet of the first fan. A damper is provided between the third air outlet and the corresponding air outlet of the first fan. As shown in FIG1 , the control method of the air conditioner includes:
获取第二风机24的转速。The rotation speed of the second fan 24 is obtained.
根据第二风机24的转速和第一风机控制风门的开合角度。The opening and closing angle of the damper is controlled according to the rotation speed of the second fan 24 and the first fan.
这里的“换热气流”指的是空调用于调节室内温度的气流。空调器工作时，第二出风口21吹出的非换热气流和第一出风口11吹出的换热气流混合，混和气流的温度相比换热气流更接近室温，出风柔和，不“硬”，舒适性更高，也使风量和风速增大，送风距离更远。进一步地，第三出风口31位于下方，或者在第一出风口11和第二出风口21都出风的情况下增大非换热气流的进风量。设置于第三出风口和第一风机的对应的出风口之间的风门的开合角度会改变第三出风口的出风量，进而改变第二出风口21的出风量。根据第二风机24的转速和第一风机的具体情况来控制风门的开合角度，从而控制第三出风口的风量，以保证第二出风口的出风量，进而使第一出风口11 和第二出风口21的风混合效果更好。The "heat exchange airflow" here refers to the airflow used by the air conditioner to adjust the indoor temperature. When the air conditioner is working, the non-heat exchange airflow blown out of the second air outlet 21 is mixed with the heat exchange airflow blown out of the first air outlet 11. The temperature of the mixed airflow is closer to the room temperature than the heat exchange airflow. The air outlet is soft and not "hard", which is more comfortable. It also increases the air volume and wind speed, and the air supply distance is farther. Furthermore, the third air outlet 31 is located at the bottom, or the air intake of the non-heat exchange airflow is increased when both the first air outlet 11 and the second air outlet 21 are outlet. The opening and closing angle of the damper set between the third air outlet and the corresponding air outlet of the first fan will change the air outlet volume of the third air outlet, and then change the air outlet volume of the second air outlet 21. The opening and closing angle of the damper is controlled according to the rotation speed of the second fan 24 and the specific situation of the first fan, so as to control the air volume of the third air outlet to ensure the air outlet volume of the second air outlet, and then make the first air outlet 11 The wind mixing effect with the second air outlet 21 is better.
进一步地，在本发明的一些实施例中，如图2所示，根据第二风机24的转速和第一风机控制风门的开合角度包括根据第二风机24的转速和第一风机的转速控制风门的开合角度，第一风机的转速为恒定值。Furthermore, in some embodiments of the present invention, as shown in Figure 2, controlling the opening and closing angle of the damper according to the rotational speed of the second fan 24 and the rotational speed of the first fan includes controlling the opening and closing angle of the damper according to the rotational speed of the second fan 24 and the rotational speed of the first fan, and the rotational speed of the first fan is a constant value.
在本发明的另一些实施例中，如图3所示，根据第二风机24的转速和第一风机控制风门的开合角度包括根据第二风机24的转速和第一风机的出风量控制风门的开合角度，第一风机的出风量为恒定值。例如，第一风机的恒定出风量为500m3/h，第二风机24的转速为T，则风门的开合角度S与第一风机的恒定出风量和第二风机24的转速之间的关系为S＝k*(500-i*T)，这里k和i均为系数。In other embodiments of the present invention, as shown in Fig. 3, controlling the opening and closing angle of the damper according to the rotation speed of the second fan 24 and the first fan includes controlling the opening and closing angle of the damper according to the rotation speed of the second fan 24 and the air volume of the first fan, and the air volume of the first fan is a constant value. For example, the constant air volume of the first fan is 500m3 /h, and the rotation speed of the second fan 24 is T, then the relationship between the opening and closing angle S of the damper, the constant air volume of the first fan, and the rotation speed of the second fan 24 is S=k*(500-i*T), where k and i are coefficients.
在本发明的一些实施例中，空调器的控制方法还包括：根据第一出风口11的出风确定第二风机24的转速。In some embodiments of the present invention, the method for controlling an air conditioner further includes: determining the rotation speed of the second fan 24 according to the air outlet of the first air outlet 11 .
进一步地，在一些实施例中，根据第一出风口11的出风温度确定第二风机24的转速，例如，第一出风口11出风温度高，则第二风机24的转速就慢，此时，不需要引入太多的非换热气流来和换热气流混合。第一出风口11出风温度低，则第二风机24的转速就快，此时，需要引入多的非换热气流来和换热气流混合，以使吹出的风不冷，人体感觉舒适。Further, in some embodiments, the rotation speed of the second fan 24 is determined according to the outlet temperature of the first air outlet 11. For example, if the outlet temperature of the first air outlet 11 is high, the rotation speed of the second fan 24 is slow. At this time, it is not necessary to introduce too much non-heat exchange airflow to mix with the heat exchange airflow. If the outlet temperature of the first air outlet 11 is low, the rotation speed of the second fan 24 is fast. At this time, it is necessary to introduce more non-heat exchange airflow to mix with the heat exchange airflow so that the blown air is not cold and the human body feels comfortable.
在另一些实施例中，根据第一出风口11的出风温度和出风量确定第二风机24的转速，例如，第一出风口11出风温度低但风量不大，则第二风机24的转速就慢，此时，不能引入太多的非换热气流来和换热气流混合，以免影响空调室内机的制冷效果。再例如，第一出风口11出风温度低且风量也大，则第二风机24的转速就快，此时需要引入多的非换热气流来和换热气流混合，以使吹出的风不冷，人体感觉舒适。在其余的另一些实施例中，壳体内还设置有用于促使第一出风口11吹出换热气流的第三风机15。根据第三风机15的转速确定第二风机24的转速。第三风机15的转速和第二风机24的转速正相关，即，第三风机15的转速越大，第二风机24的转速越大。In other embodiments, the rotation speed of the second fan 24 is determined according to the outlet temperature and the air volume of the first air outlet 11. For example, if the outlet temperature of the first air outlet 11 is low but the air volume is not large, the rotation speed of the second fan 24 is slow. At this time, too much non-heat exchange airflow cannot be introduced to mix with the heat exchange airflow, so as not to affect the cooling effect of the air conditioner indoor unit. For another example, if the outlet temperature of the first air outlet 11 is low and the air volume is large, the rotation speed of the second fan 24 is fast. At this time, more non-heat exchange airflow needs to be introduced to mix with the heat exchange airflow so that the blown air is not cold and the human body feels comfortable. In other embodiments, a third fan 15 is further provided in the housing for causing the first air outlet 11 to blow out the heat exchange airflow. The rotation speed of the second fan 24 is determined according to the rotation speed of the third fan 15. The rotation speed of the third fan 15 is positively correlated with the rotation speed of the second fan 24, that is, the greater the rotation speed of the third fan 15, the greater the rotation speed of the second fan 24.
在本发明的一些实施例中，空调器的控制方法还包括：根据第一出风口11的出风和室外环境确定第二风机24的转速。In some embodiments of the present invention, the method for controlling an air conditioner further includes: determining the rotation speed of the second fan 24 according to the air outlet of the first air outlet 11 and the outdoor environment.
在本发明的一些实施例中，空调器的控制方法还包括：根据室外环境确定第二风机24的转速。室外温度与第二风机24转速一一对应，查表可知，某个室外温度对应某个第二风机24转速，一般来说，室外温度高，第二风 机24转速低。In some embodiments of the present invention, the control method of the air conditioner further includes: determining the speed of the second fan 24 according to the outdoor environment. The outdoor temperature corresponds to the speed of the second fan 24. It can be seen from the table that a certain outdoor temperature corresponds to a certain speed of the second fan 24. Generally speaking, the higher the outdoor temperature, the faster the second fan 24. The speed of the machine 24 is low.
在本发明的一些实施例中，空调器的控制方法还包括：根据目标设定温度确定第二风机24的转速。目标设定温度与第二风机24转速一一对应，查表可知，某个目标设定温度对应某个第二风机24转速。In some embodiments of the present invention, the air conditioner control method further includes: determining the speed of the second fan 24 according to the target setting temperature. The target setting temperature corresponds to the speed of the second fan 24 one by one. It can be seen from the table that a certain target setting temperature corresponds to a certain speed of the second fan 24.
在本发明的一些实施例中，确定第二风机24的转速还包括根据第一出风口11和第二出风口21的混合出风的温度确定第二风机24的转速。In some embodiments of the present invention, determining the rotation speed of the second fan 24 further includes determining the rotation speed of the second fan 24 according to the temperature of the mixed air from the first air outlet 11 and the second air outlet 21 .

The third air outlet and the first air outlet 11 and the second air outlet 21 are not on the same wall of the housing, that is, the airflow blown out of the third air outlet does not mix with the airflow blown out of the first air outlet 11 and the second air outlet 21.
