Fig. 3, 4 and 5 respectively show a schematic structural diagram of an air conditioner indoor unit, a sectional view along the direction a-a of the air conditioner indoor unit and an explosion diagram of a counter-rotating fan set according to the present invention. The indoor unit 10 of the air conditioner comprises a shell 11, a heat exchanger 13 and a counter-rotating fan set 12. The shell 11 has a front panel 11a and a back panel 11b, the panel 11a is provided with an air outlet 110, the back panel 11b is provided with an air inlet (not shown in the figure), the air inlet is provided with an air inlet grille, the inner side of the air inlet grille is provided with a filter screen, and the heat exchanger 13 is arranged in the shell 11 and is positioned between the air inlet and the air outlet. The counter-rotating fan set 12 is installed at the air outlet, when the air conditioner runs, the counter-rotating fan set 12 runs, negative pressure is formed behind the counter-rotating fan set 12, and outside air passes through the heat exchanger 13 along the air inlet under the action of the negative pressure and then is blown to the front of the air conditioner by the counter-rotating fan 12.
The counter-rotating fan set 12 comprises a shell cover 12a and a front motor 12c1Front wind wheel 12d1A rear motor 12c2And a rear wind wheel 12d2From a front motor 12c1And a front wind wheel 12d1Form a front-mounted fan and consists of a rear-mounted motor 12c2And a rear wind wheel 12d2The rear fan is formed, and the front fan and the rear fan are arranged in a contrarotation mode. The air supply distance of the air conditioner is adjusted by adjusting the rotating speed and the rotating direction of the front fan and the rear fan. Specifically, the air conditioner is provided with the front fan and the rear fan which are in the same rotation directionThe air supply distance of (2) is increased along with the increase of the rotating speed of the fan, and is reduced along with the decrease of the rotating speed of the fan. When the air supply distance of the air conditioner is controlled to be reduced to within a certain distance, the front fan needs to be rotated reversely (the air outlet direction of the front fan is blown to the heat exchanger from the air outlet of the indoor unit of the air conditioner) so as to offset the air supply distance of the rear fan.
In the process of using the air conditioner by a user (taking refrigeration as an example), if the user is close to the air conditioner, the air outlet of the air conditioner is directly blown to the user, and strong cold air is blown to the face, so that discomfort and even sickness of the user are easily caused. Therefore, the rotating speed of the rear fan of the counter-rotating fan set can be obtained from the control program of the air conditioner in the operation process of the air conditioner. And further combining the obtained user distance, adjusting the rotating speed of the front fan, so that when the user is close to the indoor unit of the air conditioner, the wind wheel of the front fan is controlled to rotate, the wind blown out by the rear fan is cut, and the direction of the air outlet flow is changed. Because the direction of the air outlet flow is changed, the air outlet of the air conditioner is dispersed, the air quantity blown to a user from a straight surface is reduced, and the discomfort of the user caused by strong wind is avoided.
When the rotating speed of the front fan is adjusted according to the user distance and the rotating speed of the rear fan, when the air outlet direction of the front fan is opposite to the air outlet direction of the rear fan, the air outlet quantity of the rear fan is offset while the front fan breaks up the air blown out by the rear fan, so that the higher the rotating speed of the front fan is, the smaller the air outlet quantity of the air conditioner is, and the closer the air outlet distance is. Therefore, when the rotating speed of the front fan is adjusted according to the distance between the user and the rotating speed of the rear fan, and when the air outlet directions of the front fan and the rear fan are opposite, the closer the distance between the user is obtained, the larger the rotating speed of the front fan is, and the higher the rotating speed of the rear fan is, the larger the rotating speed of the front fan is.
In addition, when the air conditioner operates, the rear fan of the rotary fan set blows air indoors, the air outlet directions of the front fan and the rear fan are the same or opposite, and the front wind wheel can cut the air blown out by the rear fan as long as the rotation speed difference between the front fan and the rear fan is ensured. Meanwhile, when the air outlet direction of the front fan is the same as that of the rear fan, the higher the rotating speed of the front fan is, the larger the air outlet quantity of the air conditioner is, and the longer the air outlet distance is; when the air outlet direction of the front fan is opposite to that of the rear fan, the air outlet quantity of the rear fan is offset while the front fan breaks up the air blown out by the rear fan, so that when the rotating speed of the front fan is adjusted according to the distance between a user and the rotating speed of the rear fan, the closer the distance between the user is obtained and the lower the rotating speed of the front fan is obtained when the air outlet directions of the front fan and the rear fan are opposite.
In this embodiment, the air outlet of the indoor unit of the air conditioner according to the present invention is provided with a counter-rotating fan set, and the counter-rotating fan set includes a rear fan and a front fan which are arranged in a counter-rotating manner. In the operation process of the air conditioner, the user distance between a user and the air outlet of the air conditioner and the rotating speed of the rear fan are obtained, and the rotating speed of the front fan is adjusted according to the user distance and the rotating speed of the rear fan, so that when the user is close to the air outlet of the air conditioner, the rotating speed of the front fan is adjusted, the air blown out by the rear fan is cut, the air flow direction is changed, the air quantity and the air strength of the user and the strong wind blowing to the user are reduced, and the health of the user is prevented from being damaged by the strong wind blowing to the user.
Further, referring to fig. 6, a second embodiment of the method for controlling an air conditioner according to the present invention is based on the first embodiment, and after the step S30, the method further includes:
and step S40, acquiring the influence coefficient on the cyclone unit.
And step S50, adjusting the rotating speed and the air outlet direction of the front fan according to the user distance, the rotating speed of the rear fan and the influence coefficient.
Because the space of the air duct for installing the counter-rotating fan in the indoor unit of the air conditioner is limited, the interval between the front fan and the rear fan is narrow, and the two fans which are close to each other can send air out of the indoor unit in time, so that the diffusion of the air blown out by the rear fan in a vertical space is reduced. When two fans which are close to each other are rotated, certain influence exists between the fans. When the rotating speed of the front fan is adjusted, the influence coefficient on the cyclone fan set is obtained, and the front fan is determined according to the user distance, the rotating speed of the rear fan and the influence coefficient on the cyclone fan setThe rotational speed of (2). For example, the speed S of the front fan2＝S1*B/d，S1And S2Respectively representing the rotating speeds of the rear fan and the front fan, B representing an influence coefficient, and the numerical value is a positive number less than or equal to 1, and d representing the user distance. After the distance d between the user and the rear fan S is 3m1When the speed is 800rpm and the influence coefficient B is 0.5, the rotating speed of the front fan is adjusted to be S2＝800*0.5/3＝133rpm。
Furthermore, the influence coefficient of the cyclone unit is related to the fan parameters of the cyclone unit, and the influence coefficients of different structures on the cyclone unit are different. Common fan parameters are: the fan distance between the front fan and the rear fan is related to the number of fan blades of the fan. When the rotating speed of the front fan is adjusted, fan parameters of the wind-to-cyclone fan set are obtained, influence coefficients are obtained according to the fan parameters, and then the rotating speed of the front fan is calculated by combining the user distance and the rotating speed of the rear fan. The closer the fan distance between the two fans is, the larger the influence coefficient is, the more the fan blades of the front fan are, and the larger the influence coefficient is.
In this embodiment, when the rotation speed of the front fan is adjusted, the influence coefficient on the fan group is obtained, and the rotation speed of the front fan is determined according to the user distance, the rotation speed of the rear fan, and the influence coefficient on the fan group. When the rotational speed of the leading fan is obtained, the mutual influence when two fans rotate in the cyclone unit is considered, the leading fan after adjustment can better act on the trailing fan, the dispersity and the strength of air outlet of the air conditioner are adjusted, and the comfort requirement of a user is met.
Further, referring to fig. 7, a third embodiment of the method for controlling an air conditioner according to the present invention is based on the first or second embodiment, and further includes, after the step S20:
in step S60, it is determined whether the user distance is less than a preset distance.
And step S70, when the user distance is smaller than a preset distance, judging whether the rotating speed of the rear fan is larger than a preset rotating speed.
And step S80, when the rotating speed of the rear fan is greater than the preset rotating speed, reducing the rotating speed of the rear fan.
After the rotation speed of the rear fan is reduced, the step S30 is executed, that is, the rotation speed of the front fan is adjusted according to the user distance and the rotation speed of the rear fan.
When the obtained user distance is smaller than the preset distance and the rotating speed of the rear fan is larger than the preset rotating speed at the moment, the rotating speed of the rear fan is reduced, and then the step S30 is executed, the rotating speed of the front fan is adjusted according to the reduced rotating speed of the rear fan and the user distance, the air blown out by the rear fan is cut, the direction of the air flow is changed, and the air volume and the intensity of the air blown to the user in a straight face are reduced. The phenomenon that when a user uses the air conditioner to adjust the indoor temperature, if the user is particularly close to the air conditioner and the rotating speed of the rear fan is large, the front fan needs to be adjusted to blow air to the rear fan, the rotating speed of the front fan is relatively close to the rotating speed of the rear fan so as to offset strong wind blown out by the rear fan, and the energy consumption is high is avoided.
The air conditioners have different specifications, and the values of the preset distance and the preset rotating speed are different. Typically, the predetermined distance may be less than 1m, and the predetermined rotational speed is 500-800 rmp.
In this embodiment, when it is obtained that the user distance is smaller than the preset distance and the rotation speed of the rear fan is greater than the preset rotation speed, the rotation speed of the rear fan is reduced, and then step S30 is executed, the rotation speed of the front fan is adjusted according to the reduced rotation speed of the rear fan and the user distance, the air blown by the rear fan is cut, the airflow direction is changed, and the amount of air and the intensity of the air blown to the user in a straight direction are reduced.
