The cabinet machine comprises an upper longitudinal guide vane, a lower longitudinal guide vane and a transverse guide vane, wherein the upper longitudinal guide vane and the lower longitudinal guide vane can swing left and right, and the transverse guide vane can swing up and down. Specifically, the upper and lower longitudinal guide vanes may be controlled by different stepper motors to move the upper and lower longitudinal guide vanes in different positions.

TABLE 1
TABLE 2
Referring to fig. 3 and 4, when the cabinet is in the first stage, the airflow guided out by the upper longitudinal guide vane and the lower longitudinal guide vane is blown to the left side and the middle of the cabinet, and due to the effect of the through-flow air duct, the airflow on the left side of the cabinet is large, and at the moment, the airflow needs to be guided upwards by the transverse guide vane, so that the direct blowing of the airflow to users can be avoided. When the cabinet machine is in the second stage, the air flow guided out by the upper longitudinal guide vane and the lower longitudinal guide vane is blown to the right side of the cabinet machine, the air flow is lower at the moment, the air flow guided out by the transverse guide vane is blown to the middle of the cabinet machine, the air outlet quantity can be increased, and therefore the indoor temperature can be effectively adjusted.
With reference to fig. 5, when the upper longitudinal guide vane, the lower longitudinal guide vane and the transverse guide vane in the cabinet operate in the above two stages in sequence, the power spectral density index β value of the cabinet is greater than 1.1, and as the power spectral density index β value is greater than 1.1 according to the research, the airflow blown out of the air outlet of the cabinet can achieve the effect of natural wind, so that the comfort of the user can be improved. With reference to fig. 6, when the upper longitudinal guide vane, the lower longitudinal guide vane and the transverse guide vane in the cabinet operate sequentially in the above two stages, the flow velocity of the airflow blown out from the air outlet is less than or equal to 1.5m/s most of the time during the operation time of the cabinet, and the flow velocity of the airflow is low at this time, so that the airflow at the air outlet is closer to the natural wind. Therefore, compared with the traditional air conditioner, the air conditioner can improve the comfort of a user, and therefore the user experience can be improved.
According to the control method provided by the embodiment of the invention, the upper longitudinal guide vane, the lower longitudinal guide vane and the transverse guide vane sequentially run in the two stages under the natural wind mode of the cabinet air conditioner, so that the airflow blown out from the air outlet can be ensured to have the effect of natural wind, the comfort level of a user can be improved, and the user experience can be further improved.
In some embodiments of the present invention, as shown in table 1 and fig. 3, the indoor fan of the cabinet is operated at low or medium wind speed when the cabinet is in the first stage. The swing angle of the upper longitudinal guide vane and the lower longitudinal guide vane is large, the air quantity and the coverage area of the air flow are guaranteed, the flow velocity of the air flow blowing to a user can be reduced by enabling the indoor fan of the cabinet air conditioner to operate at a low air speed or a medium air speed, and the comfort of the user is guaranteed.
When the cabinet machine is in the second stage, the indoor fan runs at medium or high wind speed. At the moment, the swing angle of the upper longitudinal guide vane and the lower longitudinal guide vane is small, the air quantity and the coverage area of the airflow are small, and the air quantity and the flow velocity of the airflow can be increased by enabling the indoor fan to operate at medium or high air speed, so that the indoor temperature can be effectively adjusted.
In some embodiments of the present invention, as shown in table 2 and fig. 4, when the cabinet is in the first stage, the indoor fan of the cabinet is operated with a sine wave with low or medium wind speed as the average rotation speed. When the cabinet machine is in the second stage, the indoor fan runs in a sine wave with medium or high wind speed as the average rotating speed. From this, the velocity of flow of the air current of air outlet department is more disorderly to make the air current more close with the wind speed of natural wind, guaranteed user's travelling comfort.
In some embodiments of the invention, when the cabinet is in the first stage, the upper and lower longitudinal vanes are swept twice between the first and second positions, respectively, and the transverse vane is swept four times between the fifth and sixth positions;
when the cabinet is in the second stage, the upper longitudinal vane is swept six times between the second position and the third position and the transverse vane is swept two times between the fourth position and the fifth position.
Therefore, the sweeping times of the upper longitudinal guide vane, the lower longitudinal guide vane and the transverse guide vane in different stages are set to be different, so that the air flow blown out from the air outlet is more disordered and irregular, and the blowing effect of the air flow is closer to that of actual natural wind.
In some embodiments of the present invention, after the cabinet enters the natural wind operation mode, the method further includes: the upper longitudinal vane swings to a second position. The lower longitudinal vane swings to a second position. Therefore, the upper longitudinal guide vane or the lower longitudinal guide vane at any swing angle is adjusted to the second position after the cabinet air conditioner enters the natural wind mode, so that when the cabinet air conditioner just enters the first stage of the natural wind mode, the upper longitudinal guide vane or the lower longitudinal guide vane can swing by a complete angle (namely the angle of an included angle between the second position and the first position), and the air volume during the initial operation of the natural wind mode is ensured.
In some embodiments of the present invention, after the cabinet enters the natural wind operation mode, the method further includes:
the cross vane swings to a fifth position. Therefore, after the cabinet air conditioner enters the natural wind mode, the transverse guide vane at any swing angle is adjusted to the fifth position, so that when the cabinet air conditioner just enters the first stage of the natural wind mode, the transverse guide vane can swing at a complete angle (namely, the angle of the included angle between the fifth position and the fourth position) to ensure the air volume during the initial operation of the natural wind mode.
In some embodiments of the invention, when the cabinet is operating in natural wind mode, the cabinet cycles in order of the first phase and the second phase. From this, the air outlet of cabinet-type air conditioner can blow off the air current similar to natural wind in succession, has guaranteed user's travelling comfort.
In some embodiments of the invention, the upper and lower longitudinal guide vanes are straight guide vanes or wavy guide vanes, respectively. The upper longitudinal guide vane and the lower longitudinal guide vane are wavy guide vanes, and the surfaces of the upper longitudinal guide vane and the lower longitudinal guide vane are irregular, so that the wind guided out by the upper longitudinal guide vane and the lower longitudinal guide vane is more disordered and more irregularly blown out, and the effect of natural wind is favorably realized.
According to a cabinet (not shown) of the second aspect of the present invention, the control method of the cabinet according to the first aspect of the present invention is adopted.
According to the cabinet air-conditioner of the embodiment of the present invention, by using the control method, the airflow blown out by the air-conditioner 100100 has the effect of natural wind, and the comfort of the user is improved.
