As shown in fig. 1 to 5, an air conditioner according to an embodiment of the present invention may generally include a housing 10 and at least one wind-swinging device 100.

The housing 10 is provided with an air outlet 12. For example, as shown in fig. 1, the air conditioner may be a wall-mounted air conditioner, and the housing 10 may have a long shape with a horizontal longitudinal direction. The case 10 defines an accommodation space for accommodating components of a wall-mounted air conditioner. The housing 10 is provided with an air outlet 12 for discharging air flow therein, and the discharged air flow is acted by a fan in the housing 10 to accelerate the air flow flowing through the air outlet 12 for adjusting the indoor environment, such as cold air in a cooling mode, hot air in a heating mode, and fresh air flow in a fresh air mode.

Each air swinging device 100 is used for being installed at the air outlet 12 of the air conditioner to swing air at the air outlet 12, so that the air direction can be changed in a cyclic and reciprocating manner within a certain range, for example, for a wall-mounted air conditioner, the air swinging device 100 is usually used for swinging air left and right; in the case of the floor air conditioner, the air swinging device 100 generally swings the air upward and downward.

The oscillating wind device 100 includes a plurality of oscillating vanes 80, a connecting rod 93, a motor 91, a rotating member 96, a gear 97, and a sliding rod 98. Each of the swing blades 80 is directly or indirectly installed to the housing 10, and each of the swing blades 80 is rotatable in a fixed axis so that the respective swing blades 80 are synchronously linked to achieve the purpose of swinging the wind. Each of the swinging blades 80 is rotated about its own axis, marked x4 in fig. 3.

In the wall-mounted air conditioner shown in fig. 1, the casing 10 is generally elongated in a horizontal direction (the x-axis in each figure indicates the direction), and the outlet 12 is also elongated. The swing blades 80 of the air swing device 100 can be arranged along the length direction x of the housing 10 to swing air transversely, i.e. swing air left and right, at the air outlet 12.

As shown in fig. 3 to 5, the end portions of the swing vanes 80 are rotatably connected to different positions of the link 93 in the longitudinal direction, and the rotation axis is x3, so that the swing vanes 80 rotate in an interlocking manner (each around a respective x 4). The link 93 is provided with a rack 92. The rack 92 may be a separate component that is secured to the link 93 by fasteners such as screws. The rack 92 may also be part of the link 93. The rotary member 96 is configured to be rotated by the motor 91 with an axis x 1. The rotating member 96 is provided with a spool 961 located offset from the rotation axis x 1. The gear 97 is configured to be fixed in rotation about an axis x2 and is engaged with the rack 92. The gear 97 is mounted directly or indirectly to the housing 10. The sliding rod 98 is fixed to the gear 97 and has a sliding slot 981 formed therein to allow the sliding column 961 to extend therein. When the rotating member 96 rotates, the sliding column 961 moves along the length direction of the sliding groove 981, so that the gear 97 is driven to rotate, and the rack 92 and the connecting rod 93 are driven to reciprocate, so that each swing blade 80 is driven to reciprocate. For example, from the state of fig. 4 to 5, the rotation member 96 rotates counterclockwise by a certain angle so that the link 93 moves leftward by a certain distance.

The embodiment of the utility model provides an in, motor 91, rotation piece 96, slide bar 98, gear 97 and rack 92 have constituted one set of brand-new motion, and this mechanism is accurate ingenious with the syntropy rotation of motor 91 (and switch aperiodically just reversal), turns into the reciprocal translation of rack 92, when making motor 91 rotate towards a direction, just can drive a plurality of swinging blades 80 reciprocating swing, and make motor 91 more laborsaving, and power is littleer.

In some embodiments, as shown in fig. 4 and 5, the rotational member 96 may be made as a dial, i.e., made as a disc. Specifically, the rotary member 96 may be a disk, and its rotation axis x1 may be coincident with its central axis (axis passing through the center of the circle), so that its moment of inertia is greater and its rotation is more stable. In some alternative embodiments, the rotating element may be a crank (rod-shaped structure), one end of which is fixedly connected to the rotating shaft of the motor, and the other end of which is provided with a sliding column 961.

In some embodiments, as shown in fig. 4 and 5, the gear 97 is a sector gear, which is more space-saving and cost-saving than a circular gear, and the swing range of the swing blade 80 is not large, so that the reciprocating displacement of the rack 92 is not large, so that the rotation angle range of the gear 97 is small and the sector gear is sufficiently applied. Furthermore, this also leaves sufficient space for the slide bar 98. One end of the sliding rod 98 in the length direction is fixedly connected to the central shaft of the gear 97 and extends in a direction away from the gear teeth. The slide groove 981 is a linear shape having a length extending in the radial direction of the gear 97. The design makes the structure of the driving mechanism simpler, and simultaneously makes the sliding of the sliding column 961 in the sliding groove 981 smoother, so that the mechanism runs more reliably.

As shown in fig. 4 and 5, the gear 97 and the sliding rod 98 may be an integral piece.

In some embodiments, as shown in fig. 2 and 4, the air conditioner further includes a support ring 95, the support ring 95 is ring-shaped and is fixed to the housing 10, and the link 93 passes through the support ring 95 to receive the support of the support ring 95, so as to avoid that the link 93 is supported only by the gear 97, which ultimately results in an increase in power of the motor 91. The support rings 95 may be two in number and connected to each other by a connection portion 951.

In some embodiments, as shown in fig. 3 and 4, the air conditioner further includes a fixing plate 90. The fixing plate 90 is fixed to the housing 10. The motor 91 and the rotation member 96 are respectively installed at both sides of the fixed plate 90, and a rotation shaft of the motor 91 passes through a through hole (not shown) of the fixed plate 90 to connect the rotation member 96.

In some embodiments, as shown in fig. 2 and 3, each of the flaps 80 includes a plurality of layers of spaced vanes 81, 82, 83, each of the vanes 81, 82, 83 is capable of directing the direction of the airflow, which enhances the ability of each flap 80 to direct the airflow. Moreover, when the airflow passes through the space between two adjacent blades 81, 82 and 83, the airflow can also have an acceleration effect, which further enhances the guiding strength of the swing blade 80 to the airflow, so that the airflow can reach the preset swing direction more powerfully. Moreover, the multi-layer blades 81, 82 and 83 increase the layering sense of the air flow, so that the human body feels more comfortable. In addition, each swing blade 80 is provided with multiple layers of blades 81, 82 and 83, so that the number of the swing blades 80 in the whole wind swing device 100 is reduced, the linkage movement mechanism of the wind swing device 100 is relatively simple, the number of rotary friction pairs is reduced, and the probability of failure is reduced.

In some embodiments, as shown in fig. 2 and 3, the spacing distance between at least two adjacent layers of blades 81, 82, 83 is adjustable, i.e. the pitch is adjustable. For example, if there are only two layers of blades, the spacing between the two layers of blades can be adjusted. If three layers of blades are provided, the distance between the first layer and the second layer can be adjusted, the distance between the second layer and the third layer can be adjusted, and the distance between the second layer and the third layer can be adjusted. For example, as shown in fig. 3, each swing blade 80 includes three layers of blades 81, 82, 83, and two distances formed by the three blades 81, 82, 83, namely, a distance a between the blades 81 and 82, and a distance b between the blades 81 and 83 are adjustable. As shown in fig. 3, the relative pitch of the blades 81, 82, 83 of the leftmost swing blade 80 is the default pitch, the pitch of the blades 81, 82, 83 of the middle swing blade 80 is increased, and the pitch of the blades 81, 82, 83 of the rightmost swing blade 80 is decreased. By changing the distance between the blades 81, 82, 83, the airflow speed between the two blades 81, 82, 83 can be changed, thereby changing the overall flow speed of the whirling airflow. Therefore, the embodiment of the utility model provides an air-out speed is adjusted at accessible adjusting blade 81, 82, 83 interval, and the structure is very ingenious.

In some embodiments of the present invention, as shown in fig. 3, one blade 81 of each swing blade 80 is mounted to the casing 10 of the air conditioner to be rotatable about a fixed axis (rotation axis x4), and the blade 81 has a connecting arm 84. The end of the connecting arm 84 of each swing leaf 80 is rotatably connected to different portions of the link 93 in the longitudinal direction.

Fig. 6 is an exploded view of a partial structure of the wind turbine 100 according to the present invention.

As shown in fig. 6, a plurality of first mounting holes 931 are provided at different positions in the length direction on the link 93 to allow the shaft of the end of the connecting arm 84 to be inserted thereinto. Further, the air swing device 100 may further include a mounting plate 94, the mounting plate 94 being mounted to the casing 10 of the air conditioner, the mounting plate 94 being provided with a plurality of mounting shafts 941 so as to be rotatably disposed in second mounting holes 841 formed in the connecting arm 84, the second mounting holes 841 having a central axis x 4.

Fig. 7 is a schematic structural diagram of a swing blade 80 of the wind swing device 100 of the present invention; fig. 8 is an exploded view of the wind swing device 100 of the present invention; fig. 9 is an enlarged view at C of fig. 8.

In some embodiments of the present invention, as shown in fig. 7-9, each swing leaf 80 further includes a connecting plate 88. The connecting plate 88 may be elongated. Each of the blades 81, 82, 83 is attached to the connecting plate 88 at a different position in the longitudinal direction. Also, at least one of the blades 81, 82, 83 is movable in the length direction of the connecting plate 88 (parallel to the x-direction) to adjust the spacing distance thereof from the adjacent blades 81, 82, 83. That is, it is not necessary to make each of the blades 81, 82, 83 movable, and adjustment of the spacing distance can be achieved as long as part of the blades 81, 82, 83 are movable, and the remaining blades 81, 82, 83 may be fixed to the connecting plate 88 or integrally formed with the connecting plate 88.

In some embodiments of the present invention, each blade 81, 82, 83 of the swinging blade 80 can be moved along the length direction of the connecting plate 88 for easier processing of the connecting plate 88 and for richer adjustment modes.

In some embodiments of the present invention, as shown in fig. 8 and 9, each movable blade 81, 82, 83 may be provided with a penetration hole 802 to allow the connecting plate 88 to be inserted therein, so as to connect the blades 81, 82, 83 and the connecting plate 88.

In some embodiments, as shown in fig. 8 and 9, in order to position the blades 81, 82, and 83, the connecting plate 88 may be provided with a plurality of positioning through holes 882 arranged along the length direction thereof, and at least one hole wall of each insertion through hole 802 protrudes to form a positioning protrusion 8021. Fig. 9 shows a positioning boss 8021 with a dashed oval. Specifically, two opposite hole walls of the insertion through hole 802 may be respectively provided with the positioning protrusions 8021, that is, two positioning protrusions 8021 are formed. Thus, after the blades 81, 82, 83 move to the selected position, the positioning protrusion 8021 is inserted into the positioning through hole 882 at the selected position to be properly clamped therein, so as to position the blades 81, 82, 83, and allow the blades 81, 82, 83 to cause the positioning protrusion 8021 to elastically deform due to the external force to disengage from the positioning through hole 882. In this manner, the user can effectuate movement of the vanes 81, 82, 83 with a strong force, otherwise the vanes 81, 82, 83 will remain securely in the user-selected position.

The embodiment of the utility model provides a through above-mentioned structure, can fix a position blade 81, 82, 83, and can conveniently adjust the position of blade 81, 82, 83, structural design is very simple reasonable, and the cost is lower.

In some embodiments of the present invention, please refer to fig. 8, at least one ventilation through hole 801 may be disposed on at least one of the blades 81, 82, 83 of each of the swinging blades 80, so that the blades 81, 82, 83 can increase the communication between the airflows at two sides of the blades 81, 82, 83 while swinging the wind strongly, and the airflows are relatively soft. Specifically, in the blades 81, 82, and 83 having the ventilation holes 801 formed therein, the ventilation holes 801 are formed in a plurality of elongated shapes and are arranged at intervals in the width direction of the ventilation holes 801, as shown in fig. 8.

In some embodiments, as shown in fig. 1, the air conditioner further includes a wind deflector 50. The air deflector 50 is rotatably mounted at the outlet 12 of the wall-mounted air conditioner about a rotation axis parallel to the length direction thereof, and is configured to guide the air outlet direction of the outlet 12. The air deflector 50 may be a long strip whose length direction is parallel to the length direction of the air outlet 12, and the rotation axis of the air deflector 50 is parallel to the length direction.

Fig. 10 is a schematic structural view of an air deflector in the air conditioner shown in fig. 1, and fig. 11 is an enlarged view of fig. 10 at D.

As shown in fig. 10 and 11, the air guiding plate 50 includes one air guiding segment 501 or a plurality of air guiding segments 501 arranged along the length direction of the air guiding plate 50 and fixedly connected to each other. The provision of the plurality of air guide sections 501 improves the structural stability of the entire air guide plate 50. For example, as shown in fig. 10, the air guiding plate 50 includes two air guiding sections 501. Each air guiding section 501 comprises an outer plate body 51, a plurality of inner plate bodies and two end plates 54, 55. For example, as shown in fig. 2 and 3, the number of the inner plate bodies is two, and the inner plate bodies 52 and 53 are respectively formed as a three-layer air guiding plate. Of course, the number of the inner plate bodies may be three, four or more. The structure of the air guiding plate 50 will be further described with reference to fig. 10 to 11, taking a three-layer air guiding plate as an example.

As shown in fig. 10 and 11, the outer plate body 51 and each of the inner plate bodies 52 and 53 may be plate-shaped for guiding wind. The plurality of inner plates 52 and 53 are sequentially spaced apart from each other in a direction away from the first side 511 of the outer plate 51. The two large surfaces of the outer plate body 51 for guiding wind are a first side surface 511 and a second side surface 512, respectively. An air outlet interval 515 is formed between the outer plate 51 and the adjacent inner plate 52, and an air outlet interval 525 is also formed between the adjacent inner plates 52 and 53 for allowing the air flow to be blown out. The two end plates 54 are respectively located at two ends of each air guiding section 501 in the length direction, one end of the outer plate 51 and one end of the plurality of inner plates 52 and 53 in the length direction are both fixed to one end plate 54, and the other end of the outer plate and the other end plate are both fixed to the other end plate 55, so that all parts of the air guiding section 501 form a stable whole. In addition, each air guiding section 501 may further include at least one connecting section 56, where the connecting section 56 is located between the two end plates 54 and 55 and is also used for being fixedly connected with the outer plate 51 and the plurality of inner plates 52 and 53, so that the structure of the air guiding section 501 is more stable. The outer panel 51, the inner panels 52, 53 of each layer, the two end panels 54, 55 and the connecting section 56 may be integrally formed as a single piece, such as an injection molded piece. The end plate 54 may be provided with a mounting shaft 57 to be rotatably mounted to the case 10 of the wall-mounted air conditioner.

The air deflector 50 of the embodiment of the present invention includes an outer plate 51 and a plurality of inner plates 52 and 53, which make the air deflector 50 have a multi-layer structure. When the air deflector 50 conducts air guiding, a part of air outlet flow is guided by the outer plate body 51, another part of air outlet flow can enter the air outlet interval between the outer plate body 51 and the inner plate body adjacent to the outer plate body and the air outlet interval between the two adjacent inner plate bodies 52 and 53, the outer plate body 51 and the inner plate bodies 52 and 53 guide the air outlet direction of the air outlet flow together, multi-level guiding effect is achieved, the air supply flow direction discharged from the air outlet 12 is uniform, the air flow is combed more smoothly, and the comfort level of a user is better.

In some embodiments, as shown in fig. 10 and 11, the orthographic projection of the inner panel 52 to the outer panel 51 may be made to fall on the outer panel 51, rather than on an extension thereof. The orthographic projection of the inner panel 53 onto the inner panel 52 falls on the inner panel 52 rather than on its extension. That is, the width of the inner panel 52 is made smaller than that of the outer panel 51, and the width of the inner panel 53 is made smaller than that of the inner panel 52. The width direction of the outer plate 51 is the direction of the airflow along the first side 511 of the air guide plate 50. The width direction of each layer of the inner plate bodies 52, 53 is the direction in which the air flows along the inner plate bodies 52, 53. More preferably, the width of the inner panel 53 is less than 1/2 the width of the inner panel 52, and the width of the inner panel 52 is less than 1/3 the width of the outer panel 51.

Thus, the outer side of the inner plate body 53 forms a low wind speed area, an acceleration area is formed between the inner plate body 53 and the inner plate body 52, and the pressure is obviously increased when the airflow flows through the acceleration area, which is beneficial to improving the air supply distance. A flow guiding area is formed between the inner plate 52 and the outer plate 51, and is mainly used for guiding the airflow direction of the airflow main body part. In addition, in the present embodiment, the width of each layer of inner plate 52, 53 is designed to be smaller than that of outer plate 51, so as to avoid that the air guiding distance of the air outlet interval is too long, which causes too large resistance of the air flow, and the air volume and the air speed of the air outlet 12 are excessively affected. Further, the smaller the width of the inner panel body away from the outer panel body 51, the more smoothly the air flow enters the respective outlet intervals, and is guided by the inner panel bodies 52, 53. The air flow can better enter each air outlet interval whether flowing to the first side surface 511 at an angle parallel to the outer plate 51 or rushing to the first side surface 511 at an oblique angle.

In some embodiments, as shown in fig. 1, the air deflector 50 may be used to guide the blowing direction of the outlet 12, so that the wall-mounted air conditioner further includes an outer guide plate 60, and the outer guide plate 60 is rotatably disposed at the outlet 12 to open and close the outlet 12.

The air conditioner may be an indoor part of a split wall-mounted type room air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. As shown in fig. 1, a heat exchanger and a fan are provided inside the casing 10. The heat exchanger, the throttling device are connected with a compressor, a condenser and other refrigeration elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan, indoor air enters the inside of the shell 10 through the air inlet 11 at the top of the shell 10, and forms heat exchange air and enters the air duct after completing forced convection heat exchange with the heat exchanger. The fan is preferably a cross flow fan with its axis parallel to the length of the housing 10 and is located at the entrance to the air duct.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
