Fig. 1 and 2 illustrate an indoor unit of a wall-mounted air conditioner.

As shown in fig. 1 and 2, in some embodiments, the air conditioner according to the embodiments of the present utility model is a wall-mounted air conditioner including an indoor unit for wall-mounting to an indoor wall. The indoor unit comprises a shell 10, and the shell 10 is provided with an air outlet 12 for blowing out the regulated air flow. The air outlet 12 may be formed at the bottom of the front side of the housing 10. Depending on the mode of operation of the air conditioner, the conditioning air flow may be specifically a heat exchange air flow (cold air, hot air), fresh air flow, purified air flow, and/or humidified air flow, etc. The interior of the housing 10 may be provided with an indoor heat exchanger and an indoor fan. The indoor heat exchanger and the throttling device are connected with the compressor, the outdoor heat exchanger and other refrigerating elements through pipelines to form a vapor compression refrigeration cycle system. When the air conditioner is in refrigerating/heating operation, under the action of the indoor fan, indoor air enters the interior of the shell 10 through the air inlet of the shell 10, and after forced convection heat exchange with the indoor heat exchanger is completed, heat exchange airflow is formed and enters the air duct, and the air duct is led to the air outlet 12 and blows to the indoor environment.

The air guiding device 50 may be installed at the air outlet 12 of the air conditioner, and is used for guiding the flow direction of the conditioned air blown out by the air outlet 12. For example, as shown in FIG. 1, in some embodiments, the air guiding fins 100 of the air guiding device 50 may be in a coplanar state, so as to guide the conditioned air flow around the length direction (x-axis direction) of the air outlet 12 at the same angle, such as forward and upward, forward and downward, or downward. In addition, as shown in fig. 2, for example, each air guiding plate 100 of the air guiding device 50 may be adjusted to a non-coplanar state, so as to guide the adjusted air flow around the length direction (x-axis direction) of the air outlet 12 towards a plurality of angles, for example, guide part of the air flow towards the front upper side and guide the other air flow towards the front lower side, so as to enhance the dispersion degree of the air flow, and realize the multi-dimensional air supply effect.

As shown in fig. 3, for the indoor unit of the wall-mounted air conditioner, the air guide 50 may be mounted to the frame 15 inside the casing 10. The framework 15 is used for defining an air duct inside the casing 10, and an outlet of the air duct is connected to the air outlet 12.

As shown in fig. 5 to 11, the air guide device 50 for an air conditioner according to an embodiment of the present utility model may generally include a central shaft 400, a crankshaft 500, and a plurality of air guide fins 100.

A fixing portion (in one embodiment, the fixing portion may be the second gear 300) is fixed on the central shaft 400. The center shaft 400 is for rotatably mounting to a body of an air conditioner. Specifically, the fixing portion may be integrally formed with the central shaft 400. Alternatively, the fixing portion may be a separate member fixedly mounted on the center shaft 400. The fixing portion is preferably provided with a disk-like structure fixedly mounted to an end of the center shaft 400.

The crankshaft 500 has a main journal 510, a plurality of connecting rod journals 520, 530 eccentric to the main journal 510, and a plurality of cranks 540, each crank 540 being connected between adjacent connecting rod journals 520, 530. The nomenclature for the parts of the crankshaft herein pertains to the conventional nomenclature in the mechanical field. The main journal 510 is configured to be rotatably mounted to the fixed portion. Generally, the main journal 510 is located at an end of the crankshaft 500, and a central axis of the main journal 510 is a rotational axis of the entire crankshaft 500. The connecting rod journals 520, 530 are eccentric to the main journal 510, i.e. the central axes of the connecting rod journals 520, 530 are parallel to the central axis of the main journal 510 and have a spacing, which is the eccentricity. In this way, when the crankshaft 500 is driven to rotate (spin) about the central axis of the main journal 510, the respective connecting rod journals 520, 530 also rotate (revolve) about the central axis of the main journal 510.

The wind guiding sheet 100 is used for guiding wind direction, and specifically, the wind guiding sheet 100 is in a square flat plate shape as a whole. The air outlet edge of the air guide plate 100 can be tilted so as to realize upward air guide by using the coanda effect, improve the air supply effect of upward cold air and reduce the resistance to air flow when heating and downward blowing.

The plurality of wind scoopers 100 are aligned along the axial direction of the center shaft 400. Each wind-guiding fin 100 is rotatably mounted to the central shaft 400 and has at least one guide groove 120 perpendicular to the axial direction of the central shaft 400 to allow one connecting rod journal 520 or 530 to be inserted. It is preferable that each of the rod journals 520, 530 is inserted into only one guide groove 120 of the wind guiding fin 100, as shown in fig. 5 to 11. Of course, each of the rod journals 520, 530 may be inserted into the guide grooves 120 of a plurality of wind scoopers 100. In this way, when the crankshaft 500 rotates, each connecting rod journal 520, 530 slides in the corresponding guide slot 120, so as to drive the plurality of wind guiding fins 100 to rotate around the central shaft 400 in a plurality of directions, thereby adjusting the included angle relationship between the plurality of wind guiding fins 100. For example, from fig. 6 to fig. 9, the included angle between each wind guiding fin 100 is adjusted from 0 ° to an acute angle between every two adjacent wind guiding fins 100. This posture of wind scooper 100 in fig. 9 is referred to as a non-coplanar state. In this state, the air guide device 50 guides air in two directions at the same time, so that the air flow is not in a laminar state any more, but is blown out in two directions after being scattered, the air quantity blown onto a human body once is reduced, the effect similar to natural wind is achieved, and the comfort of the human body is improved.

According to the wind guiding device 50 provided by the embodiment of the utility model, the guide groove 120 is only arranged on the wind guiding sheet 100, and the connecting rod journals 520 and 530 of the crankshaft 500 penetrate through the guide groove 120, so that the connection between the crankshaft 500 and the wind guiding sheet 100 is realized, the wind guiding posture of the wind guiding sheet 100 is adjusted, and the design of a movement mechanism is very simple, reasonable and ingenious.

In some embodiments, as shown in fig. 5-11, the phase difference between each adjacent two connecting rod journals 520, 530 of the crankshaft 500 may be 180 °. In other words, the number of phases of each of the rod journals 520, 530 is two, and as noted in fig. 5, three rod journals 520 are in the same phase and three rod journals 530 are in the same phase. And three connecting rod journals 520 and three connecting rod journals 530 are sequentially staggered, and a phase difference between each connecting rod journal 520 and an adjacent connecting rod journal 530 is 180 °. So designed, the crankshaft 500 can drive each wind guiding fin 100 to rotate to a coplanar state, as shown in fig. 1 and 6. The respective air guide vanes 100 can be positioned in the same plane by simply rotating the crankshaft 500 such that the plane of the connecting rod journals 520, 530 is substantially parallel to the plane of the air guide vanes 100. In the coplanar state, the air guide plates 100 together form a long air guide plate, so that the air flow is blown out in a laminar state. When the crankshaft 500 rotates, each adjacent wind scooper 100 is rotated in two directions so as to be staggered with each other, and a non-coplanar state is formed, as shown in fig. 2 and 9. In the non-coplanar state shown in fig. 9, each of the wind guiding fins 100 has two wind guiding directions in common, and the wind guiding directions of the adjacent wind guiding fins 100 are different. When the user desires the wind guide 50 to guide wind in a conventional posture, it may be in a coplanar state. When a user wishes to reduce airflow blow-through, the air guide 50 may be adjusted to a non-coplanar condition.

In other embodiments, the number of phases of each connecting rod journal 520, 530 may be more than three, so each air guiding plate 100 cannot rotate to the coplanar state, but in the non-coplanar state, each air guiding plate 100 has more than three air guiding directions, so that the air flow is more dispersed.

In some embodiments, as shown in FIG. 5, the number of main journals 510 may be two, with two main journals 510 forming respective ends of the crankshaft 500, such that each connecting rod journal 520, 530 and each crank 540 are rod-shaped and coplanar. In this way, the structure of the crankshaft 500 is very simple. Furthermore, since each crank 540 is located between two wind scoops 100, each crank 540 can be made perpendicular to the two connecting rod journals 520, 530 to which it is connected, so that the spacing between the two wind scoops 100 can be designed to be smaller. The too large gap is avoided, so that the wind guiding blind area between the two wind guiding blades 100 is too large to influence the wind guiding effect.

In some embodiments, as shown in fig. 3 to 5, the fixing portion may be a second gear 300 mounted on an end portion of the central shaft 400. In addition, the wind guiding apparatus 50 further includes a first motor 200 and a first gear 210 driven thereby, and the first gear 210 is engaged with the second gear 300 to drive the central shaft 400 to rotate. When the central shaft 400 rotates, each wind guiding fin 100 is driven to rotate, so as to adjust the wind guiding angle of the wind guiding device 50 as a whole. Taking a wall-mounted air conditioner as an example, the pitching angle of the air flow can be adjusted by rotating the central shaft 400, so that the states of upward blowing, downward blowing, forward blowing and the like similar to the states of a conventional air deflector are realized.

The wind guiding apparatus 50 further includes a second motor 600. The second motor 600 is fixedly mounted to the second gear 300 and is connected to the main journal 510 for driving the crankshaft 500 to rotate. The second gear 300 is designed to be capable of well mounting the second motor 600 and the crankshaft 500 on the one hand, and also to constitute a speed reducer (it is necessary to make the number of teeth of the second gear 300 larger than that of the first gear 210 to achieve a speed reducing effect) so that the rotation speed of the central shaft 400 is smaller than that of the first motor 200 on the other hand.

Referring to fig. 3 to 5, an example of an indoor unit of a wall-mounted air conditioner is described as an alternative connection manner for each component of the air guiding device 50. The frame 15 has two transverse end plates 150.

At one transverse end plate 150, a first motor 200 is fixedly mounted to the outside of the transverse end plate 150 and a first gear 210 is rotatably mounted to the aperture 158 of the transverse end plate 150. The central bore of the second gear 300 is sleeved over the shaft 152 of the transverse end plate 150. The shaft 152 is a hollow shaft. The central shaft 400 passes through the inner bore 153 of the shaft 152 and is secured at its ends to the second gear 300 by means of an end cap or the like. The two mounting ears 650 of the second motor 600 are fixed to the two mounting holes 340 of the second gear 300 by screws. The shaft of the second motor 600 passes through the relief hole 330 of the second gear 300 to be connected to a connecting member 220, and the connecting member 220 is connected to a main journal 510 of the crankshaft 500. The transverse end plate 150 has an arcuate relief groove 151 centered about the shaft 152 to accommodate the connector 220. When the second gear 300 rotates, the link 220 will move in the relief groove 151.

At the other transverse end plate 150, the transverse end plate 150 has two holes to accommodate the other end of the central shaft 400 and the other main journal 510, which will not be described here.

In some embodiments, as shown in fig. 8, the surface of each wind guiding plate 100 is convexly formed with a convex strip 126 along the axial direction perpendicular to the central axis 400, and the aforementioned guiding slot 120 is opened on the convex strip 126. The ribs 126 are preferably integrally formed with the main body of the air guide plate 100, and may be integrally injection molded.

The number of the protruding strips 126 is plural, and they are arranged in the axial direction of the central shaft 400. For example, as shown in fig. 8, the number of the ribs 126 may be two, and both the ribs 126 may extend along the edge of the air guide sheet 100. A plurality of ribs 126 are provided so as to have a plurality of guide grooves 120. As the crankshaft 500 rotates, drive forces are distributed to the plurality of guide slots 120, causing each guide slot 120 to exert less force on the connecting rod journals 520, 530, making their movement smoother.

In some embodiments, as shown in fig. 7 and 8, at least one hinge seat 106 is formed to protrude from a surface of each wind guide blade 100, and the hinge seat 106 is provided with a hinge hole 110 having a radial gap 111 such that the central shaft 400 is inserted into the hinge hole 110 through the radial gap 111. In this way, when the wind guiding fin 100 is mounted, the hinge hole 110 of the wind guiding fin 100 is aligned with the central shaft 400, and the central shaft 400 is inserted into the hinge hole 110 through the radial notch 111, so that the operation is very simple. It will be appreciated that this requires that the width of the radial gap 111 be less than the diameter of the central shaft 400. The hinge base 106 is preferably integrally formed with the main body of the air guide plate 100, and may be integrally injection molded.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
