The invention provides an indoor unit of an air conditioner.
In an embodiment of the present invention, as shown in fig. 1 to 3, the indoor unit of an air conditioner includes:
the air conditioner comprises a shell 10, wherein the shell 10 is provided with an air duct 11 and a main air outlet 12 communicated with the air duct 11;
the wind wheel 20 is arranged on the air duct 11;
and the natural wind generator 30 is arranged in the air duct 11 and positioned between the wind wheel 20 and the main air outlet 12, and the cross section of the natural wind generator 30 is in a non-circular shape.
In this embodiment, the indoor unit of the air conditioner may include a volute and an air outlet frame, the air duct 11 is formed by the volute and the air outlet frame together, and the main air outlet 12 is located at an opening of the volute. The wind wheel 20 is arranged in the volute, and wind generated by the wind wheel 20 flows out of the main air outlet 12 through the air duct 11. It can be understood that the main air outlet 12 and the wind wheel 20 both extend along the length direction of the casing 10, and if the indoor unit of the air conditioner is an on-hook unit, the length direction of the casing 10 is the transverse direction, and at this time, the main air outlet 12 and the wind wheel 20 both extend along the transverse direction; if the indoor unit of the air conditioner is a cabinet unit, the length direction of the casing 10 is the longitudinal direction, and at this time, the main air outlet 12 and the wind wheel 20 both extend along the longitudinal direction. The natural wind generator 30 extends along the length direction of the wind tunnel 11, and both ends of the natural wind generator 30 may be connected to the housing 10 by a connection shaft. The cross-sectional shape of the natural wind generator 30 may be an ellipse, an eccentric wheel, or a polygon, and only a non-circular shape is required. The surface of the natural wind generator 30 may be smooth to reduce noise generated by friction between the air flow and the surface of the natural wind generator 30, and the outlet air flow can more smoothly flow through the surface of the natural wind generator 30 to form dispersed air flow. The natural wind generator 30 can change the wind resistance of the outlet air flow to form air flows with different directions and different strengths, thereby realizing the effect of natural wind and improving the comfort of human bodies.
It should be noted that, if the cross section of the natural wind generator 30 is circular, the outlet airflow flowing through the natural wind generator 30 will form similar tangential angles with two corresponding parts on the surface of the natural wind generator 30 after being shunted by contacting the natural wind generator 30, so that the wind speed and wind direction of the dispersed airflow will also tend to be similar, and the dispersed airflow will not be scattered enough and cannot effectively simulate natural wind; and this application further sets up the cross section shape of natural wind generator 30 into non-circular for the tangent angle that dispersion air current and the surperficial each position of natural wind generator 30 formed is all inequality, so that the wind speed and the wind direction of dispersion air current also diverse, has effectively disturbed the air-out air current, thereby makes the air-out effect of air conditioning indoor set simulate natural wind more effectively, has further improved the whole air-out effect of air conditioning indoor set.
Specifically, the cross-sectional shape of the natural wind generator 30 is an ellipse, and the ratio of the major axis dimension to the minor axis dimension of the cross-section of the natural wind generator 30 is greater than 1 and less than or equal to 10. In this embodiment, the natural wind generator 30 with the oval cross section can not only make the wind speed and the wind direction of the dispersed airflow different, but also reduce the obstruction of the natural wind generator 30 to the outlet airflow through the curved surface of the natural wind generator 30, thereby preventing the wind speed of the outlet airflow from being reduced as a whole and ensuring the reliability of the outlet airflow. If the ratio of the major axis to the minor axis of the cross section of the natural wind generator 30 is greater than 10, the axial section of the natural wind generator 30 passing through the major axis is too large, and the axial section of the natural wind generator 30 passing through the minor axis is too small, so that the turbulence effect on the air outlet flow is not uniform enough, and the influence on the air outlet amount is increased due to the too large axial section; therefore, the ratio of the length to the minor axis of the cross section of the natural wind generator 30 is set to be greater than 1 and less than or equal to 10, which not only ensures that the indoor unit of the air conditioner has enough air output, but also improves the air output effect of simulating natural wind.
Further, the distance between the central axis of the natural wind generator 30 and the central axis of the wind wheel 20 is 1.05 to 2.1 times of the radius of the wind wheel 20; or, the distance between the central axes of the two natural wind generators 30 and the central axis of the wind wheel 20 is 1.1 to 3.2 times of the radius of the wind wheel 20. In this embodiment, the wind wheel 20 is a cross-flow wind wheel 20, the cross section of the natural wind generator 30 is an ellipse, and the central axis of the natural wind generator 30 passes through the midpoint of the connection line of the two foci of the ellipse. If the indoor unit of the air conditioner is a cabinet unit, the distance between the central axis of the natural wind generator 30 and the central axis of the wind wheel 20 is 1.05 to 2.1 times of the radius of the wind wheel 20; if the indoor unit of the air conditioner is on-hook, the distance between the central axis of the natural wind generator 30 and the central axis of the wind wheel 20 is 1.1 to 3.2 times of the radius of the wind wheel 20. If the distance between the central axis of the natural wind generator 30 and the central axis of the wind wheel 20 is too small, the wind wheel 20 can generate wind which is too fast to contact the natural wind generator 30 to flow back, so that the wind outlet airflow near the wind wheel 20 is disordered, and the normal wind outlet performance of the wind wheel 20 is affected, and if the distance is too large, the whole volume of the indoor unit of the air conditioner can be increased, and the utilization rate of the internal space is reduced; therefore, the air outlet quantity of the indoor unit of the air conditioner can be ensured by reasonably setting the space, and the internal structure of the indoor unit of the air conditioner can be more compact.
In practical application, because the specification of the on-hook wind wheel 20 is smaller than that of the wind wheel 20 of the cabinet, that is, the air volume and the air speed of the wind wheel 20 of the hanger are relatively small, if the indoor unit of the air conditioner is on-hook, the distance between the central axis of the natural wind generator 30 and the central axis of the wind wheel 20 should be properly increased, so as to reduce the influence on the air outlet performance of the wind wheel 20 caused by the turbulence of the air flow near the wind wheel 20 and improve the air outlet stability of the indoor unit of the air conditioner.
Further, the number of the natural wind generators 30 is two, and the two natural wind generators 30 are arranged at intervals along the width direction of the air duct 11. In this embodiment. Two natural wind generators 30 set up along the width direction interval of wind wheel 20, in practical application, in order to avoid the projective plane that two natural wind generators 30 are located and the cross-section coincidence of wind channel 11 on the width direction, the mounted position of two natural wind generators 30 can be preferred one and be close to wind wheel 20, another is close to main air outlet 12 to reducible influence to the air output of air conditioning indoor set, also enable simultaneously to the vortex effect of air-out more even, further improve the air-out effect of simulation natural wind. Set up two natural wind generators 30, can enough increase the vortex area and the vortex effect to the air-out, can prevent again that natural wind generator 30 from leading to the air output reduction to occuping in air-out route, further improved the whole air-out effect of air conditioning indoor set.
Further, the distance between the central axes of the two natural wind generators 30 is 0.05 times to 1.1 times of the radius of the wind wheel 20. In this embodiment, if the distance between the middle shafts of the two natural wind generators 30 is too small, that is, the distance between the two natural wind generators 30 is too small, airflow noise is generated when the outlet airflow flows through the gap between the two natural wind generators 30, which affects user experience; if the distance between the two natural wind generators 30 is too large, the turbulent flow effect on the air outlet flow is small, and the air outlet effect of the indoor unit of the air conditioner is reduced; therefore, the distance between the central shafts of the two natural wind generators 30 is set to be 0.05 times to 1.1 times of the radius of the wind wheel 20, so that the turbulence effect of the natural wind generators 30 on the air outlet flow can be effectively guaranteed, the noise formed by the air outlet flow can be reduced, and the air outlet effect and the user experience are improved.
Further, the natural wind generator 30 may be rotatably installed in the wind tunnel 11. In this embodiment, two ends of the natural wind generator 30 are rotatably connected to the casing 10 or the volute, and the rotating natural wind generator 30 can improve the turbulence effect on the air flow, so that the air volume, the air speed, and the air direction flowing through each part of the main air outlet 12 can be changed in real time in the rotation period of the natural wind generator 30, thereby further improving the air outlet effect of the indoor unit of the air conditioner.
Further, as shown in fig. 1, the indoor unit of an air conditioner further includes a driving device 40, and an output shaft of the driving device 40 is connected to the natural wind generator 30 to drive the natural wind generator 30 to rotate. In this embodiment, the number of the driving devices 40 is two corresponding to the number of the natural wind generators 30, and the output shaft of the driving device 40 is in transmission connection with one end of the natural wind generator 30, so that the automatic rotation of the natural wind generator 30 can be realized. In practical application, the operating state of the natural wind generator 30 can be indirectly controlled by controlling the operating state of the driving device 40, for example, a user can control the rotating speed of the natural wind generator 30 by changing the rotating speed of the driving device 40, so that different air outlet effects can be realized, and different requirements can be met.
In this embodiment, 10 air outlet measurement points are set at intervals along the width direction at the air outlet of the indoor air conditioner, and the air outlet effect of the indoor air conditioner is verified by obtaining the mapping relationship between the wind speed and the wind direction of each air outlet measurement point and the change of the wind direction along with the rotation angle of the two natural wind generators 30 during the air outlet process. Wherein, the wind direction refers to the air current direction through the air-out measuring point and the horizontal reverse contained angle. The measurement results are shown in tables 1 and 2,
TABLE 1, mapping relationship table of wind direction of each wind outlet measuring point and rotation angle of two natural wind generators 30
Table 2, mapping relationship table of wind speed of each wind outlet measuring point and rotation angle of two natural wind generators 30
As can be seen from tables 1 and 2, the wind speed and wind direction at each wind outlet measurement point change correspondingly with the rotation angle of the two natural wind generators 30, which means that the two natural wind generators 30 can make the wind outlet effect of the indoor unit of the air conditioner closer to the natural wind effect, and the practicability of the indoor unit of the air conditioner is improved.
Further, the natural wind generator 30 has a rest position and a wind guiding position in the air duct 11, and at the wind guiding position, the natural wind generator 30 and the wall of the air duct 11 are arranged at intervals; in the idle position, the natural wind generator 30 is embedded in the cavity wall of the air duct 11. In this embodiment, the natural wind generator 30 is movably installed in the air duct 11, and the natural wind generator 30 can be switched between the idle position and the wind guiding position by means of translation. If the indoor unit of the air conditioner enters a natural wind mode, the natural wind generator 30 moves to a wind guide position to form a turbulent flow effect on the wind flowing through the main air outlet 12; if the indoor unit of the air conditioner exits the natural wind mode, the natural wind generator 30 moves to the idle position to avoid blocking the air flow and affecting the air output. By switching and moving the natural wind generator 30 between the idle position and the wind guide position, the indoor unit of the air conditioner can form different wind outlet effects according to the requirements of users, and the convenience of the indoor unit of the air conditioner is improved.
Further, the casing 10 further has a spare air outlet located on at least one side of the length direction of the main air outlet 12, and the indoor unit of the air conditioner further includes a damper for opening or closing the spare air outlet. In this embodiment, the quantity of reserve air outlet is two, and two reserve air outlets are located the ascending both sides of main air outlet 12 length direction respectively, and when the machine got into the natural wind mode in the air conditioning, the reserve air outlet was opened to the air door to the air-out air current in wind channel 11 can follow the outflow of reserve air outlet, in order to compensate the air output that shelters from and reduce because of natural wind generator 30, from this, can make the air-out air current of machine in the air conditioning produce the natural wind effect, can guarantee sufficient air output again, improved the practicality of machine in the air conditioning.
Further, as shown in fig. 1, the sidewall of the natural wind generator 30 is provided with a spoiler rib 31, and the spoiler rib 31 extends spirally in the circumferential direction and the axial direction of the natural wind generator 30. In this embodiment, the vortex rib 31 that the spiral extends can make each position in the natural wind generator 30 axial all be all inequality to the vortex effect of air-out air current to the air-out effect of the air-out air current of each position of air outlet length direction of flowing through respectively inequality, from this, makes the air-out air current be close the natural wind more, further improves the air-out effect of air conditioning indoor set.
