[0046] In addition, it should be noted that the use of "first", "second" and the like to define parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, and therefore cannot be understood as a limitation on the scope of protection of the present application.

[0047] For reference Figures 1 to 7 As shown, according to the embodiments of the present application, a guide air assembly comprises:

[0048] Forward and reverse rotation motor 5, connecting rod set, air guide plate 1 and air sweeping blade 3;

[0049] The output shaft of the reversible motor 5 is connected with the air deflector 1 through the linkage, and drives the air deflector 1 to swing; a helical groove 91 is arranged on the outer periphery of the output shaft;

[0050] The air sweeping linkage 4 is connected with the air sweeping blade 3; a guide pin 41 is arranged on the air sweeping linkage 4, and the guide pin 41 is partially arranged in the helical groove 91.

[0051] In the application, the helical groove 91 is arranged on the outer periphery wall of the output shaft of the reversible motor 5, and the air sweeping linkage 4 is matched and docked with the helical groove 91, so that the air deflector 1 and the air sweeping blade 3 can swing simultaneously under the driving of the same motor, the cost is saved, and the air deflector is better matched.

[0052] The reversible motor 5 can provide different rotating directions, and when a rotating direction is selected, the output shaft of the reversible motor 5 drives the air deflector 1 to swing through the linkage, wherein the swing of the air deflector 1 is achieved by connecting the air deflector 1 with a pin shaft on the machine body 2; the driving structure and mode are common, and will not be described in detail here. The process of reversing the rotating direction of the motor can also achieve the swing of the air deflector 1.

[0053] In the application, the helical groove 91 is arranged on the outer periphery of the output shaft, the helical groove 91 is arranged in the axial direction of the output shaft, a guide pin 41 is arranged on the air sweeping linkage 4 connected with the air sweeping blade 3, and the guide pin 41 is partially arranged in the helical groove 91, so that when the output shaft rotates, the helical groove 91 drives the guide pin 41 to move at least in the axial direction of the helical groove 91, and the air sweeping linkage 4 and the air sweeping blade 3 also move at the same time, so as to complete the air sweeping action of the air sweeping blade 3. The air sweeping blade 3 is connected with the machine body 2 through a pin shaft, and is hingedly connected with the air sweeping linkage 4 on one side; this structure is a conventional structure, so that the air sweeping linkage 4 can drive the air sweeping blade 3 to swing.

[0054] The guide pin 41 is similar to a pin structure, one end of the guide pin 41 is fixed on the air sweeping linkage 4, and the other end of the guide pin 41 extends into the helical groove 91 and avoids abutting against the helical groove 91; when the output shaft rotates, the position of the helical groove 91 abutting against the guide pin 41 changes along the axial direction of the output shaft, so that the side wall surface of the helical groove 91 extrudes the guide pin 41 to move along the axial direction.

[0055] In some embodiments,

[0056] A straight cylinder 9 is sleeved on the output shaft, and the helical groove 91 is arranged on the outer periphery wall of the straight cylinder 9.

[0057] The helical groove 91 is arranged on the output shaft of the forward and reverse motor 5, which will affect the use of the output shaft. The straight cylinder 9 is sleeved on the output shaft, and the helical groove 91 is arranged on the outer peripheral wall of the straight cylinder 9. In this way, the air sweeping connecting rod 4 can be away from the position of the output shaft, and the guide pin 41 can be conveniently connected with the helical groove 91.

[0058] In some embodiments,

[0059] The guide pin 41 and the inner wall of the helical groove 91 are arranged in sliding or rolling fit.

[0060] Since the guide pin 41 abuts against the inner wall of the helical groove 91, the helical groove 91 has a corresponding force on the guide pin 41 during the rotation of the output shaft, and thus a corresponding friction force also exists.

[0061] When the guide pin 41 and the inner wall of the helical groove 91 are arranged in sliding fit, the inner wall surface of the helical groove 91 is at least coated with lubricating oil to reduce the friction force; or the guide pin 41 and the helical groove 91 can be arranged in rolling fit, and a roller is sleeved on the end of the guide pin 41 inserted into the helical groove 91, and the roller and the side wall of the helical groove 91 are arranged in rolling fit. The above two structures can ensure that the helical groove 91 can well push the guide pin 41 to move when the helical groove 91 rotates with the output shaft.

[0062] In some embodiments,

[0063] The connecting rod set includes a first crankshaft 6, an air guide connecting rod 7 and a second crankshaft 8. One end of the first crankshaft 6 is connected with the output shaft, and the other end is hingedly connected with one end of the air guide connecting rod 7. The other end of the air guide connecting rod 7 is hingedly connected with one end of the second crankshaft 8, and the other end of the second crankshaft 8 is connected with the air guide plate 1.

[0064] For the structure in which the air guide plate is driven to swing by the connecting rod set of the forward and reverse motor 5, the connecting rod set can be formed in a manner that the first crankshaft 6, the air guide connecting rod 7 and the second crankshaft 8 are sequentially hingedly connected. One end of the connecting rod set is connected with the output shaft, and the other end is connected with the air guide plate, especially the pin shaft of the air guide plate 1 connected with the machine body 2. In this way, when the output shaft rotates in one direction, the first crankshaft 6 and the second crankshaft 8 both follow corresponding rotation to drive the air guide plate to rotate, thereby realizing the air guide function.

[0065] The air guide plate 1 can also be connected with the machine body 2 through a pin shaft, and one side is hingedly connected with the other end of the connecting rod set. The connecting rod set can adopt a structure in which the first crankshaft 6 and the air guide connecting rod 7 are combined. In this way, the air guide connecting rod 7 pushes and pulls one side of the air guide plate 1 to move under the action of the first crankshaft 6, thereby realizing the swing of the air guide plate 1.

[0066] In some embodiments,

[0067] The air sweeping connecting rod 4 is arranged in parallel with the output shaft.

[0068] The sweep wind link 4 and the output shaft are provided with a guide pin 41 and a helical groove 91, and the sweep wind link 4 and the output shaft do not require a positional relationship without affecting the interaction between the guide pin 41 and the helical groove 91. In this application, the two are arranged in parallel, which occupies less space, is easy to assemble, and has good driving effect.

[0069] In some embodiments,

[0070] The plurality of air deflectors 1 are sequentially hinged to the same transmission rod 11, and the linkage group is connected to one of the air deflectors 1.

[0071] The air deflector 1 is usually provided with multiple air deflectors 1. In order to make the air deflection directions of all air deflectors 1 consistent, the same transmission rod 11 is used to drive all air deflectors 1. At this time, even if one air deflector 1 is driven to rotate, the remaining air deflectors 1 will also rotate together through the transmission rod 11.

[0072] In some embodiments,

[0073] The plurality of sweep wind blades 3 are sequentially hinged to the sweep wind link 4.

[0074] Similarly, the plurality of sweep wind blades 3 are sequentially hinged to the sweep wind link 4 to achieve synchronous sweeping and consistent sweeping direction, thereby increasing the sweeping efficiency.

[0075] According to another aspect of the application, a cabinet type air conditioner is provided, which comprises the air deflection assembly as described above.

[0076] In some embodiments,

[0077] The cabinet type air conditioner further comprises a machine body 2, and the forward-reverse motor 5 is fixed on the machine body 2. The output shaft is vertically arranged and located in the upper part of the machine body 2.

[0078] For the cabinet type air conditioner, the air outlet 21 and the air outlet frame 22 of the machine body 2 are usually arranged in a long strip shape. The corresponding output shaft is also arranged in a vertical direction. The remaining components associated with the output shaft, including the guide pin 41 and the linkage group, are arranged in the upper part of the machine body 2, thereby achieving synchronous driving of the air deflector 1 and the sweep wind blade 3.

[0079] In some embodiments,

[0080] The air deflector 1 is arranged in a vertical direction to form left-right direction sweeping. The sweep wind blade 3 is arranged in a horizontal direction to form up-down direction sweeping.

[0081] The wind guide plate 1 is extended in the vertical direction to sweep the wind in the left and right directions, while the wind sweeping blades 3 are extended in the horizontal direction to sweep the wind in the up and down directions.

[0082] In actual operation, since the axial length of the spiral groove 91 in the output shaft is set, when moving to one end of the spiral groove 91, it is necessary to change the running direction of the forward and reverse motor 5 to move the air guide plate 1 and the wind sweeping blade 3 in the opposite direction; the movement frequency of the air guide plate 1 and the wind sweeping blade 3 can also be adjusted by changing the pitch.

[0083] The cabinet air conditioner of the present application relies on only one motor as a power source to simultaneously drive the upper and lower air sweeping blades 3 and the left and right air guide plates 1 to swing and sweep the air, which saves costs and can better cooperate with the air guide.

[0084] The wind sweeping blade 3 is driven by the straight tube 9 structure, and the wind guide plate 1 is driven by the connecting rod group. This can avoid limiting the wind sweeping angle by the dead point position, realize wide-area wind sweeping, and improve the stability of the mechanism.

[0085] like Figure 1-3 The cabinet air conditioner structure shown has an air outlet 21 on the front, an air outlet frame 22 is provided in the position of the air outlet 21, and the air outlet frame 22 is provided with four vertically placed air guide plates 1 and multiple horizontally placed air sweeping blades 3 to achieve multi-angle air sweeping; the traditional air sweeping components mainly composed of left and right air guide plates 1 and upper and lower air sweeping blades 3 are driven by two motors to sweep the air left and right and up and down respectively, which increases the cost and cannot better cooperate to achieve all-round air guidance.

[0086] The present application can also realize the omnidirectional wind sweeping function up, down, left and right. The wind sweeping mechanism is mainly composed of a wind guide plate 1, a wind sweeping blade 3, a wind guide connecting rod 7, a wind sweeping connecting rod 4, a straight cylinder 9, a guide pin 41, a forward and reverse motor 5, etc., wherein the wind sweeping connecting rod 4 is limited by the wind sweeping blade 3 fixed on the air duct, resulting in that it can only move up and down, and in turn acts on the wind sweeping blade 3 to drive the wind sweeping blade 3 to sweep the air up and down, the forward and reverse motor 5 and the straight cylinder 9 are relatively fixed (the straight cylinder 9 can only rotate around the central axis), the first crankshaft 6 is fixedly assembled with the straight cylinder 9 and cannot rotate relative to each other, and the second crankshaft 6 is fixedly assembled with the straight cylinder 9 and cannot rotate relative to each other. The crankshaft 8 is fixedly assembled with the air guide plate 1, and the transmission rod 11 is assembled with all the air guide plates 1. In this way, when one of the air guide plates 1 rotates, the other air guide plates 1 will rotate together. The upper and lower air sweeping connecting rods 4 and the straight cylinder 9 are connected and transmitted by the guide pin 41. The guide pin 41 fixed on the air sweeping connecting rod 4 is inserted into the spiral groove 91 and can move in the spiral groove 91 of the straight cylinder 9. However, since the guide pin 41 on the air sweeping connecting rod 4 is constrained to move only up and down, when the straight cylinder 9 rotates, it will drive the guide pin 41 to move upward and downward synchronously. The specific implementation method is as follows:

[0087] 1. The forward and reverse motor 5 fixed to the lower end of the straight cylinder 9 drives the straight cylinder 9 to rotate;

[0088] 2. When the straight cylinder 9 rotates, it will also synchronously drive the guide pin 41 to run around the spiral groove 91. Since the wind sweeping link 4 is restricted to only up and down movement, the guide pin 41 will drive the wind sweeping link 4 to move up and down, and the wind sweeping link 4 will drive the wind sweeping blade 3 to sweep the air up and down;

[0089] 3. When the straight cylinder 9 rotates, the first crankshaft 6 at the upper end will also rotate synchronously, driving the air guide connecting rod 7 to operate; the air guide connecting rod 7 will also drive the second crankshaft 8 to rotate. After the second crankshaft 8 rotates, an air guide plate 1 fixed to the second crankshaft 8 will begin to swing. Since all the air guide plates 1 are connected in series through the transmission rod 11, all the air guide plates 1 will swing together to achieve left and right air sweeping;

[0090] The air sweeping device proposed in this application only uses one motor to achieve the up, down, left, and right air sweeping functions, reducing costs and simultaneously achieving left and right air guidance and up and down air sweeping functions, better coordination and achieving all-round air guidance. In addition, it can avoid the air sweeping angle being limited by the dead point position, can achieve wide-area air sweeping, and has better mechanical stability.

[0091] It is easy for those skilled in the art to understand that the above embodiments can be freely combined and superimposed on the premise that there is no conflict.

[0092] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application. The above description is merely a preferred embodiment of the present application. It should be noted that those skilled in the art can make various improvements and variations without departing from the technical principles of the present application, and such improvements and variations shall also be considered within the scope of protection of the present application.
