Description

Technical Field

[0001] The invention relates to an air conditioner, in particular to a multi-directional wide-angle air guide device and an air conditioner. Background Art

[0002] The wind direction of the indoor unit of the split air conditioner is mainly determined by the wind guide plate and the sweeping blade. The sweeping plate determines the up and down wind direction, and the sweeping blade determines the left and right wind direction. According to the different structures of the sweeping blades, they can be divided into automatic sweeping blades and manual sweeping blades. The manual sweeping blades need to adjust the angle of the sweeping blades before installation, but manual adjustment is required when user needs change; the automatic sweeping blades are installed with a drive motor and driven by the drive motor; the drive motor drives the connecting rod hinged on the sweeping blade to move left and right, thereby driving the swing of the sweeping blade to achieve left and right air supply.

[0003] However, this automatic air sweeping method is difficult to achieve multi-directional wide-angle air supply, and the cost of this automatic air sweeping structure is relatively high due to the existence of the driving motor. In addition, when there are multiple users in the room and they are in different positions, there will be air supply requirements in different directions, but the existing air conditioner is difficult to meet this air supply demand, so a wide-angle multi-directional air supply device is needed. Summary of the invention

The driving groove is provided on the back side of the cam and is composed of an arc track and an eccentric track. Among them, the center of the arc track is located on the axis of the main shaft of the driving motor; a connecting portion perpendicular to the axis direction of the sliding rod is provided at the lower end of the sliding rod, and the connecting portion extends horizontally into the driving groove; when the incomplete gear meshes with the driven gear, the connecting portion at the lower end of the sliding rod cooperates with the arc track in the driving groove.

[0012] Preferably, the arc track of the driving groove in the cam and the incomplete gear are on the same side, and the radian of the arc track is equal to the radian of the incomplete gear; the positions of the two ends of the incomplete gear are the same as the positions of the two ends of the arc track.

[0020] 2. The multi-directional wide-angle air guiding device of the present invention can not only cause the left air-sweeping blade and the right air-sweeping blade to swing in the same direction, so as to realize unilateral air supply (that is, the left air-sweeping blade and the right air-sweeping blade supply air to the left side at the same time, or supply air to the right side at the same time); it can also cause the left air-sweeping blade and the right air-sweeping blade to swing in the opposite direction, so as to realize air supply to the left and right sides respectively (for example, the left air-sweeping blade supplies air to the left side, and the right air-sweeping blade supplies air to the right side), which can meet different air supply requirements of users.

[0026] The present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0027] Embodiment 1

[0028] Referring to Figures 1 - 9 , the multi-directional wide-angle air guiding device of the present invention includes a left air-sweeping blade 2, a right air-sweeping blade 11 provided on the housing of the air conditioner, and an air supply device for driving the left air-sweeping blade 2 and the right air-sweeping blade 11 to swing in the same direction or in opposite directions.

[0029] Referring to Figures 1 - 9 , the air supply device includes a first connecting rod 1, a second connecting rod 12, and an air supply driving mechanism for driving the first connecting rod 1 and the second connecting rod 12 to move in the same direction or in opposite directions. Among them, the first connecting rod 1 is snap-connected to the left air-sweeping blade 2; the second connecting rod 12 is snap-connected to the right air-sweeping blade 11; the air supply driving mechanism includes a sliding rod 5, a vertical driving mechanism for driving the sliding rod 5 to move vertically, and a swinging driving mechanism for driving the sliding rod 5 to swing left and right. Among them, the upper end of the sliding rod 5 is respectively connected to the first connecting rod 1 and the second connecting rod 12 through a third connecting rod 3 and a fourth connecting rod 4. Among them, one end of the third connecting rod 3 is hinged to the first connecting rod 1, and the other end is hinged to the upper end of the sliding rod 5; one end of the fourth connecting rod 4 is hinged to the second connecting rod 12, and the other end is hinged to the upper end of the sliding rod 5;

[0030] The swinging driving mechanism is used to drive the sliding rod 5 to swing to achieve the same-direction swinging of the left air-sweeping blade 2 and the right air-sweeping blade 11; the vertical driving mechanism is used to drive the sliding rod 5 to move vertically to achieve the opposite-direction swinging of the left air-sweeping blade 2 and the right air-sweeping blade 11.

[0031] Referring to Figures 1 - 9 , the swinging driving mechanism includes a sleeve rod 6, a cam 8, and a driving motor 10 for driving the cam 8 to rotate. Among them, the sleeve rod 6 is sleeved on the sliding rod 5, and a driven gear 7 is provided at the lower end of the sleeve rod 6, and the driven gear 7 is fixedly connected to the lower end of the sleeve rod 6; the cam 8 is installed on the main shaft of the driving motor 10, and an incomplete gear 9 that cooperates with the driven gear 7 is provided on the cam 8, and the incomplete gear 9 intermittently meshes with the driven gear 7 during the rotation of the cam 8.

[0032] With the above settings, when it is necessary to drive the left air-sweeping blade 2 and the right air-sweeping blade 11 to swing left or right synchronously, the driving motor 10 drives the cam 8 to rotate, thereby driving the incomplete gear 9 on the cam 8 to rotate. When the incomplete gear 9 meshes with the driven gear 7 at the lower end of the sleeve rod 6, the incomplete gear 9 drives the driven gear 7 to rotate, thereby driving the sleeve rod 6 and the slide rod 5 to swing left and right. When the slide rod 5 swings left and right, it drives the first connecting rod 1 and the second connecting rod 12 to move left and right through the third connecting rod 3 and the fourth connecting rod 4, thereby driving the left air-sweeping blade 2 and the right air-sweeping blade 11 to swing left and right; during this process, the swinging direction of the slide rod 5 is determined by the rotation direction of the main shaft of the driving motor 10, that is: (1). When the driving motor 10 rotates clockwise, the sleeve rod 6 and the slide rod 5 swing to the right, thereby driving the first connecting rod 1 and the second connecting rod 12 to move to the right, so as to drive the left air-sweeping blade 2 and the right air-sweeping blade 11 to swing to the left, realizing left-side air supply; (2). When the driving motor 10 rotates counterclockwise, the sleeve rod 6 and the slide rod 5 swing to the left, thereby driving the first connecting rod 1 and the second connecting rod 12 to move to the left, so as to drive the left air-sweeping blade 2 and the right air-sweeping blade 11 to swing to the right, realizing right-side air supply.

[0033] Among them, the cam 8 in this embodiment is an eccentric cam, the cam 8 and the incomplete gear 9 are of an integral structure, and the sleeve rod 6 and the driven gear 7 at its lower end are also of an integral structure. Among them, the outer circle radius of the incomplete gear 9 is larger than the radius of the driven gear 7 at the lower end of the sleeve rod 6, and the purpose is to reserve enough space for the withdrawal of the gear engagement; the part with gears in the cam 8 controls the left and right air-sweeping blades to deflect in the same direction, and the part without gears controls the left and right air-sweeping blades to deflect in opposite directions, realizing multi-directional wide-angle air supply.

[0034] In addition, the rotating shaft 15 of the driven gear 7 is matched with the bottom shell shaft, and a return spring can be added according to actual needs to ensure that when the incomplete gear 9 disengages from the driven gear 7, the left and right air-sweeping blades can be reset. After the left and right air-sweeping blades are reset, the driving motor 10 continues to rotate in the same direction, and the slide rod 5 starts to move in the vertical direction (mainly relying on the vertical downward movement of the slide rod 5), thereby pushing the left air-sweeping blade 2 to deflect to the left and the right air-sweeping blade to deflect to the right.

[0035] See Figures 1 - 9, the vertical driving mechanism includes a driving groove provided on the cam 8, the driving groove is provided on the back side of the cam 8, and the driving groove is composed of an arc track 8-1 and an eccentric track 8-2. Among them, the center of the arc track 8-1 is located on the axis of the main shaft of the driving motor 10; a connecting portion perpendicular to the axis direction is provided at the lower end of the sliding rod 5, the connecting portion extends horizontally into the driving groove, and is located at the upper end of the driving groove in the cam 8; when the incomplete gear 9 meshes with the driven gear 7, the connecting portion at the lower end of the sliding rod 5 cooperates with the arc track 8-1 in the driving groove; among them, the arc track 8-1 of the driving groove in the cam 8 and the incomplete gear 9 are on the same side, and the radian of the arc track 8-1 is equal to the radian of the incomplete gear 9; the positions of both ends of the incomplete gear 9 are the same as those of both ends of the arc track 8-1.

[0036] Through the above settings, when the driving motor 10 drives the incomplete gear 9 to mesh with the driven gear 7, since the connecting portion at the lower end of the sliding rod 5 is located in the arc track 8-1 of the driving groove at this time, and the center of the arc track 8-1 is located on the axis of the main shaft of the driving motor 10, therefore, the cam 8 will not drive the sliding rod 5 to move vertically, that is, when the connecting portion at the lower end of the sliding rod 5 is in the arc track 8-1 of the driving groove, the sliding rod 5 will not move vertically and will only swing left and right under the drive of the sleeve rod 6; when the incomplete gear 9 is separated from the driven gear 7, the connecting portion at the lower end of the sliding rod 5 enters the eccentric track 8-2 during the rotation of the cam 8. At this time, since the incomplete gear 9 is separated from the driven gear 7, the sliding rod 5 no longer swings left and right. During the continuous rotation of the cam 8, the eccentric track gradually approaches the axis of the main shaft of the driving motor 10, causing the sliding rod 5 to continuously move towards the axis of the driving motor 10, thereby driving the sliding rod 5 to move vertically, and further driving the first connecting rod 1 and the second connecting rod 12 to move towards or away from each other, so that the left air-sweeping blade 2 and the right air-sweeping blade 11 can move in the opposite direction, that is, the left air-sweeping blade 2 can send air to the left side and the right air-sweeping blade 11 can send air to the right side. Specifically:

[0037] When the incomplete gear 9 disengages from the driven gear 7, the connecting portion at the lower end of the sliding rod 5 enters the eccentric track 8-2, causing the sliding rod 5 to move downward and gradually approach the axis of the driving motor 10. As a result, the sliding rod 5 drives the first connecting rod 1 and the second connecting rod 12 to move in opposite directions, that is, the first connecting rod 1 moves to the right and the second connecting rod 12 moves to the left. Furthermore, the left air-sweeping blade 2 swings to the left to achieve left-side air supply, while the right air-sweeping blade 11 swings to the right to achieve right-side air supply. During the continuous rotation of the cam 8, the connecting portion at the lower end of the sliding rod 5 gradually moves upward, driving the sliding rod 5 to move upward, causing the first connecting rod 1 and the second connecting rod 12 to move towards each other, so that the left air-sweeping blade 2 swings to the right and the right air-sweeping blade 11 swings to the left, thus achieving reset. After the left air-sweeping blade 2 and the right air-sweeping blade 11 are reset, the connecting portion at the lower end of the sliding rod 5 enters the arc track 8-1, realizing the same-direction swing of the left air-sweeping blade 2 and the right air-sweeping blade 11.

[0038] In addition, the arc track 8-1 of the driving groove in the cam 8 and the incomplete gear 9 are arranged on the same side, and the radian of the arc track 8-1 is equal to the radian of the incomplete gear 9; the positions of both ends of the incomplete gear 9 are the same as those of both ends of the arc track 8-1, so that when the incomplete gear 9 starts to engage with the driven gear 7, the connecting portion at the lower end of the sliding rod 5 enters the arc track 8-1. This can ensure the separation of the left-right swing and the vertical movement of the sliding rod 5, preventing interference, and ensuring that the left air-sweeping blade 2 and the right air-sweeping blade 11 can swing in the same direction or in opposite directions, and the two swinging modes are selected alternately without interference.

[0039] In this embodiment, the trajectory size of the driving groove in the cam 8 is adjusted according to actual needs, and the included angle between the third connecting rod 3 and the fourth connecting rod 4 is adjusted to control the amplitude of the up-and-down movement of the sliding rod 5. In this way, it is ensured that during the process of the up-and-down movement of the sliding rod 5 to drive the third connecting rod 3 and the fourth connecting rod 4 to move, the included angle between the third connecting rod 3 and the fourth connecting rod 4 does not exceed 180° during the process of changing from small to large. The driving groove in the cam 8 is divided into an arc track 8-1 and an eccentric track 8-2, and the angle of the arc track 8-1 with the axis of the main shaft of the driving motor 10 as the center is the same as the angle of the incomplete gear 9, that is, when the incomplete gear 9 disengages from the driven gear 7, the sliding rod 5 can start to gradually approach the axis of the driving motor 10 under the drive of the eccentric track 8-2, and after reaching the nearest point, gradually move away from the axis of the driving motor 10 and enter the arc track 8-1 again.

[0040] See Figures 1 - 9, a first limiting block 14 is provided at the position where the first connecting rod 1 is hinged to the third connecting rod 3, and the first limiting block 14 is used to limit the swinging angle of the third connecting rod 3; a second limiting block 13 is provided at the position where the second connecting rod 12 is hinged to the fourth connecting rod 4, and the second limiting block 13 is used to limit the swinging angle of the fourth connecting rod 4; the first limiting block 14 and the first connecting rod 1, and the second limiting block 13 and the second connecting rod 12 are all of an integral structure, and the inclination angles of the first limiting block 14 and the second limiting block 13 are determined according to the distance between the left air-sweeping blade 2 and the right air-sweeping blade 11 and the maximum deflection angle of the blades. The lengths of the first limiting block 14 and the second limiting block 13 need to ensure that the third connecting rod 3 and the fourth connecting rod 4 do not deflect when the sliding rod 5 swings left and right.

[0041] When the incomplete gear 9 cooperates with the driven gear 7, the rotation of the main shaft of the driving motor 10 will drive the left and right swinging of the sliding rod 5. Since a first limiting block 14 is provided at the hinged position of the first connecting rod 1 and the third connecting rod 3, and a second limiting block 13 is provided at the hinged position of the second connecting rod 12 and the fourth connecting rod 4. When the sliding rod 5 swings to the left, the first limiting block 14 at the first connecting rod 1 is subjected to a thrust force, pushing the first connecting rod 1 to move to the left, and the fourth connecting rod 4 drags the second connecting rod 12 to move to the left; when the sliding rod 5 swings to the right, the second limiting block 13 at the second connecting rod 12 is subjected to a thrust force, pushing the second connecting rod 12 to move to the right; the movements of the first connecting rod 1 and the second connecting rod 12 respectively drive the left air-sweeping blade 2 and the right air-sweeping blade 11 to deflect, so as to realize the adjustment of the left and right wind directions. When the incomplete gear 9 disengages from the driven gear 7, the first connecting rod 1 and the second connecting rod 12 are automatically restored to the initial position under the deflection force of the left air-sweeping blade 2 and the right air-sweeping blade 11 (here, it can be realized by setting a return spring. When the incomplete gear 9 is separated from the driven gear 7, the return spring pulls the sleeve rod 6 and the sliding rod 5 back to the initial position, that is, the forward position). Subsequently, the driving motor 10 drives the cam 8 to continue to rotate. At this time, the sleeve rod 6 will not swing left and right, and the cam 8 will start to drive the sliding rod 5 to move up and down. Among them, when the sliding rod 5 moves down, the third connecting rod 3 and the fourth connecting rod 4 will push the first connecting rod 1 and the second connecting rod 12 to move to the left and right respectively, so that the left air-sweeping blade 2 and the right air-sweeping blade 11 deflect, realizing that the left air-sweeping blade 2 sweeps the wind to the left and the right air-sweeping blade sweeps the wind to the right, so as to realize wide-angle air supply.

[0042] See Figures 1 - 9 , the multi-directional wide-angle air guiding device of the present invention has the following two working modes:

[0043] (1), left and right air supply mode

[0044] When the multi-directional wide-angle air guiding device of the present invention is in its initial position, the incomplete gear 9 meshes with the driven gear 7. When it is necessary to blow air in a fixed direction to the left or right, the driving motor 10 rotates, driving the sleeve rod 6 to swing, and further driving the deflection of the left and right air-sweeping blades, so as to realize the air supply mode to the left or right. When it is necessary to switch from blowing air to the left to blowing air to the right or from blowing air to the right to blowing air to the left, the driving motor 10 first rotates a certain angle in the original direction to disengage the gears. At this time, the left and right air-sweeping blades automatically return to their original positions due to the force of elastic deformation, and then the driving motor 10 rotates in the reverse direction to perform the switching.

[0045] (2) Wide-angle air supply mode: When the multi-directional wide-angle air guiding device of the present invention is in its initial position, the driving motor 10 first rotates in a certain direction, and the left and right air-sweeping blades also deflect accordingly. When the incomplete gear 9 disengages, the left and right air-sweeping blades automatically return to their original positions. At this time, the cam 8 drags the slide rod 5 to move downward, and further causes the first connecting rod 1 and the second connecting rod 12 to move in opposite directions, and the left and right air-sweeping blades deflect in opposite directions, thereby realizing wide-angle air sweeping; when the multi-directional wide-angle air guiding device of the present invention switches from the state of blowing air to the left or right to wide-angle air supply, the driving motor 10 continues to rotate in the same direction. After the incomplete gear 9 disengages, the cam 8 drags the slide rod 5 to move, thereby realizing wide-angle air sweeping.

[0046] Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is that the left air-sweeping blade 2 and the right air-sweeping blade 11 can also be driven by two groups of motors respectively, so as to realize the separate control of the left air-sweeping blade 2 and the right air-sweeping blade 11, and wide-angle air supply can also be realized.
