Fig. 2 is a schematic view of a swing blade mechanism in an embodiment. The invention provides an air conditioner, which comprises an air conditioner body, wherein a cross-flow fan, a heat exchanger and an air channel surrounded by an air conditioner framework are arranged in the air conditioner body, the air channel comprises an air inlet air channel and an air outlet air channel, the cross-flow fan is arranged between the air inlet air channel and the air outlet air channel, indoor air can be extracted from an air inlet to the air conditioner body through the rotating acting force of the cross-flow fan, the indoor air flow sequentially flows through the air inlet air channel, the cross-flow fan and the air outlet air channel and exchanges heat with the heat exchanger, and then the air is blown into the indoor environment again through an air outlet of the air conditioner.
In order to realize the adjustment of the air outlet angle of the air outlet flow of the air conditioner, the air outlet duct of the air conditioner is provided with the air swinging mechanism which is used for adjusting the left and right air outlet directions of the air outlet flow, namely adjusting the transverse air outlet angle of the air outlet flow.
Specifically, the air swinging mechanism mainly comprises a swinging blade group, a rotating shaft, a driving device and the like, wherein the swinging blade group is used for guiding the flow direction of air flow, so that the air flow is forced to turn and flows along the direction parallel to the surface of the swinging blade when flowing through the surface of the swinging blade. The rotating shaft is connected with the swinging blades and used for driving the adjustment of the blade surface angles of the swinging blades so as to form air outlet airflow facing different air supply angles. The driving device is in driving connection with the rotating shaft and is used for driving the rotating shaft to rotate around the self axial direction.
In an embodiment, the swing blade group comprises a plurality of swing blades arranged at a set interval, and a channel for air flow to flow through is formed between every two adjacent swing blades. Meanwhile, the blade surfaces of the adjacent swing blades are arranged in parallel, so that air flow flowing through the channel between every two swing blades can be blown into an indoor environment at the same air outlet angle, the consistency of the air outlet direction is ensured, and the problems of turbulent flow interference and the like caused by the inconsistent air outlet flow direction are avoided.
In the embodiment, the rotating shaft is in a slender straight round rod structure and can rotate around the self axial direction under the driving force of the driving device. In the rotating process of the rotating shaft, the position of the rotating shaft does not change, namely, the rotating shaft does not move transversely or do not move vertically and the like when rotating. Therefore, compared with a connecting rod which transversely moves in the conventional swing blade air guide device, the swing blade air guide device does not need to reserve a moving space in the transverse direction, so that the space occupation of the swing blade mechanism can be reduced, and the space utilization rate of the starting amount of the air conditioner is improved.
In the embodiment, the air outlet of the air conditioner is rectangular, the longitudinal long edge of the air outlet is parallel to the horizontal direction, and the section of the air outlet duct is matched with the shape of the air outlet, so that the longitudinal direction of the air outlet duct is the horizontal direction parallel to the longitudinal long edge of the air outlet. The rotating shaft of the air swinging mechanism is arranged in the air outlet duct and is parallel to the air outlet duct, namely the rotating shaft is arranged in the air outlet duct in a way that the axial direction of the rotating shaft is parallel to the horizontal direction, so that a plurality of swinging blades distributed along the axis of the rotating shaft can cover most of the air outlet path of the air flow, and the air guiding effect of the air swinging mechanism is improved.
In other embodiments, the air outlet of the air conditioner is also rectangular, and the longitudinal long side of the air outlet is parallel to the vertical direction, so that the longitudinal direction of the air outlet duct referred to in the present invention is the vertical direction parallel to the longitudinal long side of the air outlet. In order to facilitate the explanation of the arrangement position of the rotating shaft of the air conditioner in the subsequent embodiments, the invention is mainly explained by using an air outlet type air conditioner with longitudinal long edges parallel to the horizontal direction.
In the embodiment, the plurality of swing blades of the swing blade group are all in the same shape and structure, each swing blade is provided with a pore structure for the rotating shaft to penetrate through, the pore structures on all the swing blades are arranged in the same position, and the pore structures are also the same, so that after the rotating shaft penetrates through all the swing blades, the swing blades of the swing blade group can be uniformly distributed in the longitudinal direction of the air outlet duct, and the consistency of the air outlet angle after adjustment is ensured.
In the embodiment, as shown in fig. 3, the rotating shaft sequentially penetrates through each of the swing blades of the swing blade group, and the axial direction of the rotating shaft and the blade surface of each of the swing blades are fixedly arranged at the same angle. In order to prevent the angle of an included angle formed by the swing blade and the rotating shaft from changing in the rotating process of the rotating shaft, the rotating shaft and the swing blade are relatively fixedly connected through the limiting piece.
Specifically, the locating part is integrated structure, including section of thick bamboo portion and trip portion. The cylindrical part is of a cylindrical structure with a certain wall thickness, the cylindrical part is internally provided with a through groove with a smooth inner wall surface along the axial direction, and the through groove is a circular groove, the diameter of the through groove is slightly larger than that of the rotating shaft, so that the rotating shaft can conveniently penetrate through the through groove, and the friction resistance is reduced.
The outer wall of the barrel part is provided with an annular groove, the diameter direction of a circle where the annular groove is located and the axial direction of the barrel part form a certain included angle, and the included angle is the same as or close to the included angle formed by the leaf surface of the swing leaf and the axial direction of the rotating shaft. The swing blade is sleeved outside the barrel part, the diameter of the pore structure formed in the swing blade is slightly smaller than the diameter of the circle where the annular groove is located, so that the swing blade can be clamped in the synchronous annular groove through the pore structure of the swing blade and is arranged at an included angle with the axis of the barrel part, the swing blade and the rotating shaft can be arranged at the same included angle, and the included angle between the swing blade and the rotating shaft can be always kept at a fixed angle due to the limiting effect of the annular groove.
The clamping hook part is arranged at one synchronous end, the hook end faces to the axis of the cylinder part, and the distance between the hook end and the synchronous axis is smaller than the radius length of the through groove. The rotating shaft is provided with a groove matched with the clamping hook part, so that after the rotating shaft penetrates through the barrel part, the hook end of the clamping hook part can be embedded into and clamped in the groove of the rotating shaft and forms a stop together with the groove in the axial direction of the rotating shaft, and the limiting part is prevented from moving in a staggered manner in the axial direction of the rotating shaft.
The rotating shaft is provided with a plurality of grooves at set intervals along the axial direction of the rotating shaft, and each swing blade of the swing blade group is fixed at the position of the corresponding groove through an independent limiting piece, so that the plurality of swing blades can keep the same or similar interval on the rotating shaft.
In another embodiment of the present invention, the swing blade and the corresponding limiting member are an integrated structure, and the structure of the limiting member matching with the rotating shaft is similar to that of the previous embodiment, so that there is no need to provide an annular groove on the outer wall of the cylinder portion of the limiting member, the swing blade and the limiting member can be integrally molded, and the complexity of the structure of the limiting member matching with the swing blade is reduced.
In the embodiment, the driving device is a component such as a motor arranged in the air conditioner, and a shaft of the motor can drive the rotating shaft to synchronously rotate through a transmission part such as a gear. Optionally, the motor is a motor capable of rotating in two directions, so as to drive the rotating shaft to rotate in a clockwise direction or a counterclockwise direction respectively.
Fig. 4 is a schematic view of a swing angle of the swing blade mechanism of the present invention when the swing blade is located at different positions, wherein, for convenience of describing an outlet wind direction, a direction in fig. 4 is taken as an orientation of an outlet wind channel, that is, an original outlet direction of the outlet wind flow without installing the swing blade mechanism, and at this time, the outlet direction of the outlet wind flow is perpendicular to an axial direction of the rotating shaft. Fig. 4 a is a first reference yaw direction corresponding to a first reference yaw angle of the yaw blade when the rotating shaft is at the first reference radian position; b is a first swing direction corresponding to a first swing angle of the swing blade when the rotating shaft is at the first radian position; c is a second reference swing direction corresponding to a second reference swing angle of the swing blade when the rotating shaft is at a second reference radian position; and D is a second swing direction corresponding to the second swing angle of the swing blade when the rotating shaft is positioned at the second radian position.
As can be seen from fig. 4, when the rotating shaft is located at the first reference radian position of a or the second reference radian position of C, the blade surface of the flap is parallel to the a direction of the air outlet duct, at this time, the first reference flap angle and the second reference flap angle are both 0, and the air outlet flow blows into the indoor environment along the a direction.
When the rotating shaft is located at the first arc position of B, the radial direction of the swing blade faces to the left, a first swing angle α 1 is formed between the radial direction of the swing blade and the direction a, and at this time, the air outlet airflow of the air conditioner is exhausted in a direction biased to the left by the angle α 1 relative to the direction a.
When the rotating shaft is located at the second arc position of D, the radial direction of the swing blade faces to the right, a second swing angle α 2 is formed between the radial direction of the swing blade and the direction a, and at this time, the air outlet airflow of the air conditioner is exhausted in a direction of an angle α 2 which is approximately right relative to the direction a.
In an embodiment of the invention, when the rotating shaft is located at the first arc position and the second arc position, the maximum swing angle is reached, the first swing angle a 1 and the second swing angle a 2 are the same, and the two swing angles are equal to an included angle a formed by each swing blade and the axial direction of the rotating shaft.
The following describes the variation of the wind-swinging angle of the swinging blade during the rotation of the rotating shaft according to the first embodiment of the present invention.
(1) When the rotating shaft of the wind swinging mechanism rotates in the same direction (clockwise direction), the starting position of the rotation of the rotating shaft is assumed to be the first reference arc position shown in a of fig. 4, at this time, the first reference wind swinging angle is 0, and the wind outlet air flow blows into the indoor environment in the direction a.
(2) When the rotating shaft rotates from the first reference radian position to the first radian position shown in B of figure 4, the radian of the rotation of the rotating shaft is pi/2, namely the rotation angle of the rotating shaft is 90 degrees. At this time, the radial direction of the swing blade faces to the left (the left side is set to be the first side), the radial direction of the swing blade and the direction a form a first swing angle α 1, and the outlet air flow of the air conditioner is discharged in the direction of the angle α 1 deviated from the direction a;
when the rotating shaft rotates to the first radian position from the first reference radian position, the swinging wind angle formed by the radial direction of the swinging blade and the direction a is gradually increased from 0 degree to alpha 1, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the first reference radian position and the first radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the first reference radian position to the first radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging vane still faces to the left side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 1)/2, so that the outlet airflow of the air conditioner can be discharged at an angle (a 1)/2 which is left relative to the a direction.
(3) When the rotating shaft rotates from the first radian position to the second reference radian position shown in C of figure 4, the radian of the rotation of the rotating shaft is pi/2, namely the rotation angle of the rotating shaft is 90 degrees. At the moment, the radial direction (namely the blade surface direction) of the swinging blade is parallel to the direction a, at the moment, the second reference swinging angle is 0, and the outlet airflow blows into the indoor environment along the direction a;
when the rotating shaft rotates from the first radian position to the second reference radian position, the swing wind angle formed by the radial direction of the swing blade and the direction a is gradually reduced from alpha 1 to 0 DEG, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the first radian position and the second reference radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the first radian position to the second reference radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging vane still faces to the left side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 1)/2, so that the outlet airflow of the air conditioner can be discharged at an angle (a 1)/2 which is left relative to the a direction.
(4) When the rotating shaft rotates from the second reference radian position to the second radian position shown in D of figure 4, the radian of the rotation of the rotating shaft is pi/2, namely the rotation angle of the rotating shaft is 90 degrees. At this time, the radial direction of the swing blade faces to the right side (the right side is set to be the second side), a second swing angle α 2 is formed between the radial direction of the swing blade and the direction a, and the outlet air flow of the air conditioner is exhausted in a direction at an angle α 2 which is approximately right relative to the direction a;
when the rotating shaft rotates from the second reference arc position to the second arc position, a swing wind angle formed by the radial direction of the swing blade and the direction a is gradually increased from 0 degree to alpha 2, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the second reference radian position and the second radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the second reference radian position to the second radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging vane still faces to the right side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 2)/2, so that the outlet airflow of the air conditioner can be discharged in the direction of (a 2)/2 angle which is offset to the right of the a direction.
(5) When the rotating shaft rotates from the second radian position to the first reference radian position shown in A of figure 4, the radian of the rotation of the rotating shaft is pi/2, namely the rotation angle of the rotating shaft is 90 degrees. At the moment, the radial direction (namely the blade surface direction) of the swinging blade is parallel to the direction a, at the moment, the first reference swinging angle is 0, and the outlet airflow blows into the indoor environment along the direction a;
when the rotating shaft rotates to the first reference radian position from the second radian position, the swing wind angle formed by the radial direction of the swing blade and the direction a is gradually reduced from alpha 2 to 0 DEG, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the second radian position and the first reference radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the second radian position to the first reference radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging blade still faces to the right side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 2)/2, so that the outlet airflow of the air conditioner can be discharged in the direction of (a 2)/2 angle which is offset to the right of the a direction.
It can be seen from the above process that after the rotating shaft completes one rotation operation from A-B-C-D-A, the whole rotation radian of the rotating shaft is 2 pi, namely the rotating shaft returns to the first reference radian position again after 360 degrees, thus, the air conditioner can generate the air supply effect of left and right air sweeping by controlling the continuous and cyclic rotation of the rotating shaft, thereby improving the use comfort of users.
The above embodiment is described in the process of driving the rotating shaft to rotate in the same direction by the driving device, and since the driving motor used in the present invention can also rotate in two directions, the change of the wind swinging angle of the swinging blade during the two-way rotation of the rotating shaft of the present invention is further described in the following embodiment (two).
(1) Assuming that the initial position of the rotation of the rotating shaft is the first reference arc position shown in a of fig. 4, at this time, the first reference swing angle is 0, and the outlet airflow blows into the indoor environment along the direction a.
(2) In the case where the rotary shaft of the yaw mechanism rotates in the first rotation direction (assuming that the first rotation direction is the clockwise direction), when the rotary shaft rotates from the first reference arc position to the first arc position shown in B of fig. 4, the arc of rotation of the rotary shaft is pi/2, that is, the rotation angle of the rotary shaft is 90 °. At this time, the radial direction of the swing blade faces to the left, a first swing angle α 1 is formed between the radial direction of the swing blade and the direction a, and the air outlet flow of the air conditioner is exhausted in a direction biased to the left by the angle α 1 relative to the direction a;
when the rotating shaft rotates to the first radian position from the first reference radian position, the swinging wind angle formed by the radial direction of the swinging blade and the direction a is gradually increased from 0 degree to alpha 1, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the first reference radian position and the first radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the first reference radian position to the first radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging vane still faces to the left side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 1)/2, so that the outlet airflow of the air conditioner can be discharged at an angle (a 1)/2 which is left relative to the a direction.
(3) After the rotating shaft of the wind swing mechanism rotates to the first radian position in the first direction, the driving motor rotates reversely and drives the rotating shaft of the wind swing mechanism to rotate to the first reference radian position again in the second direction (assuming that the second direction is the anticlockwise direction), and the rotating radian of the rotating shaft is pi/2, namely the rotating angle of the rotating shaft is 90 degrees. At the moment, the radial direction (namely the blade surface direction) of the swinging blade is parallel to the direction a, at the moment, the first reference swinging angle is 0, and the outlet airflow blows into the indoor environment along the direction a;
when the rotating shaft rotates from the first radian position to the first reference radian position, the swing wind angle formed by the radial direction of the swing blade and the direction a is gradually reduced from alpha 1 to 0 DEG, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the first radian position and the first reference radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the first radian position to the first reference radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging vane still faces to the left side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 1)/2, so that the outlet airflow of the air conditioner can be discharged at an angle (a 1)/2 which is left relative to the a direction.
(4) After the rotating shaft of the wind swinging mechanism rotates to the first reference radian position in the second rotation direction, the driving device continues to drive the rotating shaft to rotate to the second radian position shown in D of figure 4 from the first reference radian position in the second rotation direction, and the rotation radian of the rotating shaft is pi/2, namely the rotation angle of the rotating shaft is 90 degrees. At this time, the radial direction of the swing blade faces to the right side, a second swing angle α 2 is formed between the radial direction of the swing blade and the direction a, and the air outlet flow of the air conditioner is exhausted in a direction of an angle α 2 which is approximately right relative to the direction a;
when the rotating shaft rotates from the first reference arc position to the second arc position, a swing wind angle formed by the radial direction of the swing blade and the direction a is gradually increased from 0 degree to alpha 2, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the first reference radian position and the second radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the first reference radian position to the second radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging vane still faces to the right side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 2)/2, so that the outlet airflow of the air conditioner can be discharged in the direction of (a 2)/2 angle which is offset to the right of the a direction.
(5) After the rotating shaft of the wind swing mechanism rotates to the second radian position in the second direction, the driving motor rotates reversely and drives the rotating shaft of the wind swing mechanism to rotate to the first reference radian position again in the first direction, and the rotating radian of the rotating shaft is pi/2, namely the rotating angle of the rotating shaft is 90 degrees. At the moment, the radial direction (namely the blade surface direction) of the swinging blade is parallel to the direction a, at the moment, the first reference swinging angle is 0, and the outlet airflow blows into the indoor environment along the direction a;
when the rotating shaft rotates to the first reference radian position from the second radian position, the swing wind angle formed by the radial direction of the swing blade and the direction a is gradually reduced from alpha 2 to 0 DEG, therefore, in the air swinging control process of the air conditioner, the rotating shaft can be controlled to rotate to other radian positions between the second radian position and the first reference radian position, so that the radial direction and the a direction of the swinging blade form a swinging wind angle corresponding to the radian position, for example, when the rotating shaft rotates by pi/4 radian from the second radian position to the first reference radian position, the actual rotating angle of the rotating shaft is 45 degrees, at the moment, the radial direction of the swinging blade still faces to the right side, however, the swing angle formed by the radial direction of the swing blade and the a direction is (a 2)/2, so that the outlet airflow of the air conditioner can be discharged in the direction of (a 2)/2 angle which is offset to the right of the a direction.
It can be seen from the above process that after the rotating shaft completes one rotation operation of a-B-a-D-a, the rotating shaft returns to the first reference radian position again, so that the air conditioner can generate air supply effect of left and right air sweeping by controlling the continuous and cyclic bidirectional rotation of the rotating shaft, thereby improving the use comfort of users.
In both embodiments, the first reference arc position is used as the initial rotation position of the rotating shaft, the initial rotation position of the rotating shaft may be other arc positions than the first reference arc position when the air conditioner is in operation, and the actual rotation process of the rotating shaft may refer to the rotation process of the above embodiments.
