As shown in fig. 1 to 7, an air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10, at least one slide rail 15, an air deflector 50, and at least one swing arm 61.

The casing 10 defines an accommodation space in which other components of the air conditioning indoor unit are disposed and a conditioned air flow, such as cool air or warm air, is produced. The housing 10 is provided with an air outlet 12 for delivering the conditioned air flow to the indoor environment. Please refer to fig. 1. Fig. 1 shows an embodiment of a wall-mounted air conditioning indoor unit, in which the casing 10 and the outlet 12 are each an elongated shape extending in the horizontal transverse direction, and the length direction thereof is marked as the x direction in fig. 1.

The slide rail 15 is formed on the housing 10 or mounted on the housing 10. That is, the slide rail 15 may be a part of the housing 10, for example, a groove opened on the inner side surface of the housing 10. Alternatively, the slide rail 15 may be a separate member and fixed to the housing 10 by a fastener. The number of the slide rails 15 may be one or more. It is understood that when the number of the slide rails 15 is plural, the shapes of the respective slide rails 15 are completely uniform.

The air deflector 50 is disposed at the air outlet 12, and functions to guide the direction of the air flow. For example, in the embodiment shown in fig. 1 to 7, the air guiding plate 50 is an elongated strip extending along the horizontal direction, and the air guiding plate 50 guides the pitch angle of the outlet airflow of the outlet 12, that is, adjusts the included angle between the outlet direction and the horizontal plane. The air deflector 50 has at least one sliding portion 51, and each sliding portion 51 is disposed in one of the sliding rails 15, i.e., the number of the sliding portions 51 is the same as the number of the sliding rails 15. The sliding portion 51 may be a column shape, which is provided inside the groove-shaped slide rail 15. The sliding part 51 may be formed on the air guide plate 50; alternatively, the sliding portion 51 may be a separate member and attached to the air guide plate 50 by a fastener.

Each swing arm 61 is pivotable about its first end c, and the second end d of the swing arm 61 is rotatably connected to the air deflector 50, see fig. 3 and 4. For example, the second end d of the swing arm 61 may be provided with a rotating shaft, and the rotating shaft may be rotatably installed in the hole of the wind deflector 50, so as to realize the rotating connection. The rotation axes of the first end c and the second end d of the swing arm 61 are perpendicular to the plane of the slide rail 15.

The air-conditioning indoor unit is configured as follows: by rotating the swing arm 61 around the first end c thereof, the sliding portion 51 slides along the slide rail 15, thereby changing the position of the air deflector 50, for example, driving the air deflector 50 to several positions shown in fig. 2 to 7.

The utility model discloses machine in air conditioning is through setting up slide rail 15 and swing arm 61 for the motion of aviation baffle 50 is for the slip along slide rail 15 and around its sliding part 51 pivoted combined motion, makes aviation baffle 50 change the position of locating through this kind of combined motion, in order to open or close air outlet 12, and adjust its wind-guiding angle. The utility model discloses well aviation baffle 50's motion mode is novel ingenious, has promoted the discrimination of product and user's use experience

In some embodiments of the present invention, as shown in fig. 2 to 7, the indoor unit of the air conditioner further includes a motor 63. The motor 63 is used for driving the swing arm 61 to rotate around the first end c thereof. The motor 63 may be directly connected to the first end of the swing arm 61 to directly drive the swing arm to rotate, or may be indirectly connected to the first end of the swing arm 61 through a transmission mechanism such as a gear. The motor 63 may be a stepper motor.

Further, in some embodiments, the air conditioning indoor unit is configured to: allowing the air deflection plate 50 to reciprocate between a first closed position, an open position, and a second closed position. That is, the air deflection plate 50 can move to the above three states, but not only to have three operation states, but the air deflection plate 50 can move to a state between the three states.

In the first closed state, as shown in fig. 2 and 3, the air deflector 50 blocks the air outlet 12, and the second end d of the swing arm 61 is located between the sliding portion 51 and the first end c of the swing arm 61. As shown in fig. 3, the first end a and the second end b of the air deflector 50 are located at the upper end and the lower end adjacent to the air outlet 12, respectively. When the indoor unit of the air conditioner is in a stop state, the air deflector 50 can be in a first closed state.

In the first closed state shown in fig. 2, the motor 63 is allowed to rotate forward (the motor 63 rotates clockwise and the motor 63 rotates counterclockwise in the viewing angle shown in fig. 2 to 7), so that the air deflector 50 is turned to an open state in which the air deflector 50 is parallel to the swing arm 61, that is, the air deflector 50 moves from the state shown in fig. 2 to the state shown in fig. 4 to finally move to the open state shown in fig. 5. When the air guide plate 50 is in the state shown in fig. 4, air can be guided downward. When the air deflector 50 is in the open state shown in fig. 5, the outlet 12 is fully opened.

In the open state shown in fig. 5, the motor 63 is allowed to rotate forward to rotate the sliding part 51 in the sliding rail 15 (at this time, the sliding part 51 does not slide in the sliding rail 15), so that the air deflector 50 is opened continuously to make the opening angle larger. Alternatively, the motor 63 may be rotated reversely to rotate the sliding portion 51 in the sliding rail 15 (at this time, the sliding portion 51 does not slide in the sliding rail 15), so that the air deflector 50 is rotated to a second closed state for shielding the air outlet 12, that is, from fig. 5 to fig. 6, and finally reaches the state shown in fig. 7, where the first end a and the second end b of the air deflector 50 are located at the lower end and the upper end adjacent to the air outlet 12, respectively. The air guiding plate 50 is kept between the open state and the second closed state to change the air guiding angle of the air guiding plate 50.

It will be appreciated, of course, that the deflector 50 can reciprocate, i.e., the deflector 50 can also return to the open state from the second closed state and then return to the first closed state from the open state.

The air conditioner indoor unit provided by the embodiment of the utility model can not only utilize the motor 63 to rotate positively to make the air deflector 50 reciprocate between the first closed state and the open state; the motor 63 can also be used for reversing to enable the air deflector 50 to rotate from the opening state to the second closing state, so that the air guiding position of the air deflector 50 is richer, and the air supply mode of the indoor unit of the air conditioner is more diversified.

In some embodiments of the present invention, as shown in fig. 2 to 7, the air-conditioning indoor unit is a wall-mounted air-conditioning indoor unit, and the casing 10, the air outlet 12 and the air deflector 50 are all long strips extending horizontally. And, each slide rail 15 extends in the width direction of the air outlet 12.

More specifically, as shown in fig. 2 to 7, the air outlet 12 may be opened in a front lower region of the housing 10, and may be further directed to a front lower direction, so as to enlarge an air blowing angle. A first end of each swing arm 61 is adjacent a lower end of the outlet 12. Thus, when the air deflector 50 moves to the state shown in fig. 4, air can be guided downwards, and when the indoor unit of the air conditioner is in a heating state, air can be guided downwards by the air deflector 50, so that a sinking air supply effect can be achieved, a foot warming experience is achieved, and the situation that hot air cannot reach the ground is avoided. When the air deflector 50 moves to the state shown in fig. 6, the air can be deflected forward or forward and upward, so that the effect of upward air delivery is achieved. When the indoor unit of the air conditioner is used for refrigerating, the air supply distance and the air supply height can be increased by operating the upward air supply mode, so that cold air is scattered downwards at a high point at a far position, and the diffusivity is better.

In some embodiments, as shown in fig. 2 to 7, the rotation axis of the first end c of the swing arm 61 can be located in the slide rail 15, so as to make the structure of the motion mechanism more compact. The second end d of the swing arm 61 is rotatably connected to a central portion of the air guiding plate 50 in the width direction, for example, a section of the middle 1/5 in the width direction. Each of the sliding portions 51 may be disposed at an end, for example, an end a, in the width direction of the air deflector 50, and no matter where the air deflector 50 moves, one end of each of the sliding portions is located on the air outlet section of the air outlet 12, so that the sliding portion can better guide the air. When the air guiding plate 50 moves to the first closed state, the length direction of the swing arm 61 can be parallel to the width direction of the air guiding plate 50, that is, the two ends of the sliding portion 51 and the swing arm 61 are collinear.

In some embodiments, as shown in fig. 2 to 7, at least a section of each sliding rail 15 engaged with the sliding portion 51 may extend along a straight line, so that the air deflector 50 moves smoothly and laborsaving during the forward rotation and the reverse rotation of the motor 63.

In some embodiments, the number of the sliding rails 15 and the sliding portions 51 is two, the two sliding rails 15 are respectively formed on two lateral side walls of the casing 10, and the two sliding portions 51 are respectively located at two ends of the air deflector 50 in the length direction.

The number of the motor 63 and the swing arm 61 may be one, and it may be disposed adjacent to one end of the air guide plate 50 in the length direction, so as to facilitate the control of the motor 63.

In some embodiments, as shown in fig. 2, a heat exchanger 30 and a fan 40 may be disposed in the housing 10. The top of the casing 10 may be provided with an air inlet, and the heat exchanger 30, the throttling device, a compressor, a condenser and other refrigeration components arranged in the air conditioner outdoor unit are connected through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 40, the indoor air enters the inside of the casing 10 through the air inlet, after the forced convection heat exchange with the heat exchanger is completed, heat exchange air is formed and enters the air duct 20, and then the air is blown to the indoor through the air outlet 12 of the casing 10, so that the indoor air is adjusted. The fan 40 is preferably a cross flow fan having an axis parallel to the length of the housing 10, and is disposed at the inlet of the air duct 20. The heat exchanger 30 may be a three-stage heat exchanger.

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.
