It should be noted that the figures only illustrate some of the alternative blowing modes of the present invention, and that some blowing modes are not explicitly listed.

An air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10, at least one flow divider 50, at least one air guide 60, and at least one cover 15.

Wherein the cabinet 10 defines at least one air duct 20. The cabinet 10 according to the embodiment of the present invention includes a framework for forming a basic frame of the indoor unit, and body components such as a volute and a volute tongue for defining the air duct 20. The conditioned air flow produced by the indoor unit of the air conditioner is blown to the indoor environment through the outlet of the air duct 20, thereby completing the conditioning process of the indoor air. The adjusting air flow can be cold air produced by the indoor unit of the air conditioner in a refrigerating mode and hot air produced by the indoor unit of the air conditioner in a heating mode. The number of the air ducts 20 may be one, or may be plural, and each figure illustrates an embodiment in which the number of the air ducts 20 is two.

Each of the flow dividing members 50 is provided at an outlet of one of the air ducts 20 to divide the outlet of the air duct 20 into the first supply port 11 and the second supply port 12 which are arranged side by side in the width direction thereof. As shown in fig. 1, the two sides of the left air duct 20 in the width direction are a1 and B1, respectively, and the two sides of the right air duct 20 in the width direction are a2 and B2, respectively. When the first outlet 11 and the second outlet 12 are both open, the air flow is divided into two paths by the flow divider 50 and flows to the first outlet 11 and the second outlet 12 when the air flow is blown out from the duct 20. Each of the air deflectors 60 is rotatably installed at one of the first blowing openings 11 for guiding the air-out direction thereof. Of course, the air guiding plate 60 can also be rotated to cover the first air outlet 11, so that the air is not discharged or the air outlet cross section is the smallest, and only a small amount of air can be discharged, as shown in fig. 3. Each cover 15 is movably mounted to the casing 10 for opening and closing one of the second blowing ports 12.

In the embodiment shown in fig. 1 to 7, the casing 10 extends in a vertical column shape, that is, the air conditioning indoor unit is a vertical air conditioning indoor unit. The outlet of the air duct 20 is vertical, and the flow dividing member 50 is in a vertically extending column shape, so that the first air supply outlet 11 and the second air supply outlet 12 are respectively in a vertical bar shape and located on the left and right sides of the flow dividing member 50. The air deflector 60 is vertical and has its axis of rotation parallel to its length. Of course, in the embodiment not illustrated in the drawings, the indoor unit of the air conditioner may also be a wall-mounted type, the casing 10 is a long strip extending horizontally in the length direction, and the outlet of the air duct 20, the flow dividing member 50, the air guide plate 60 and the cover plate 15 are correspondingly long strips extending horizontally and horizontally, which will not be described again in detail.

The air supply adjusting modes of the air conditioner indoor unit provided by the embodiment of the utility model are very rich, so that the air conditioner indoor unit can adjust different air supply modes according to different operation conditions and different user requirements, the corresponding air supply outlet is started, other air supply outlets are stopped, the integral wind direction, the integral air quantity and the like of the air conditioner indoor unit are changed, and a user can obtain better air supply experience. For example, only the first air blowing port 11 may be opened to blow air through the first air blowing port 11, as shown in fig. 2, and the air guide plate 60 may guide the direction of the air blown through the first air blowing port 11. Alternatively, only the second air blowing port 12 is opened, and the air guide plate 60 is rotated to a position where the first air blowing port 11 is closed as much as possible, so that air is blown mainly from the second air blowing port 12, as shown in fig. 3. Alternatively, only the second supply port 12 is opened and the first supply port 11 is closed by the cover 15, as shown in fig. 4. Alternatively, the first and second

air blowing ports

11 and 12 are opened simultaneously to maximize the air volume, as shown in fig. 5.

In addition, in some embodiments, the air conditioning indoor unit is configured to have a converging air delivery mode. Referring to fig. 6, in the converging blowing mode, the cover 15 fully or half opens the second blowing opening 12 to expose at least the area near the splitter 50. The half-open state is a state in which the second blowing port 12 is partially opened, and the opening degree is not strictly limited to 50%, and fig. 6 illustrates the half-open state. The air guide plate 60 opens the first air blowing port 11. In the airflow direction (i.e. the direction from the inner side of the air duct 20 to the outer side of the air duct 20), the distance between the inner wall of the air deflector 60 and the inner wall of the cover plate 15 gradually decreases, so that the airflow in the air duct 20 is distributed to both sides by the flow divider 50, and then is converged into one stream outside the housing 10 under the guidance of the inner walls of the air deflector 60 and the cover plate 15, thereby forming a convergent air supply effect.

Due to the addition of the splitter 50, in the forward flowing process of the adjusting airflow, the adjusting airflow respectively flows to the two sides of the splitter 50 under the guidance of the rear surface of the splitter 50, and respectively flows out of the gap between the splitter 50 and the inner wall of the cover plate 15 and the gap between the splitter 50 and the inner wall of the air deflector 60, so that the air outlet speed is higher. And because the distance between the inner wall of the air deflector 60 and the inner wall of the cover plate 15 is gradually reduced, the two air flows are gradually converged towards the center direction of the air flow in the outward flowing process and are converged into one air flow, so that the wind power is very strong, the air supply distance is longer, and the requirements of the indoor unit of the air conditioner on long-distance air supply and strong air supply are met.

In addition, the utility model utilizes the inner wall of the air deflector 60 and the inner wall of the cover plate 15 to conduct polymerization and guide of airflow, and because the air deflector 60 can rotate and the cover plate 15 can move, the polymerization angle and the air quantity of polymerization air supply can be changed by changing the positions of the air deflector 60 and the cover plate 15, and the design is very ingenious. For example, the air deflector 60 may be rotated to make the air outlet end closer to (far away from) the splitter 50, so that the tapering strength between the air deflector 60 and the cover plate 15 is greater (smaller), the convergence strength is greater (smaller), and the air outlet speed is greater (smaller). For example, the movable cover 15 makes the opening degree of the second blowing port 12 larger (smaller) and makes the amount of the aggregated air larger (smaller).

In some embodiments, as shown in fig. 1 and 6, the length direction of the air deflector 60 can be perpendicular to the width direction of the outlet of the air duct 20, and the rotation axis y of the air deflector 60 is parallel to the length direction thereof. The air deflector 60 includes an inner plate 62 and an outer plate 61 which are disposed at an interval and fixedly connected to each other, so that they form a double-layer structure. The width (ab) of the inner plate 62 is smaller than the width (cd) of the outer plate 61, when the air deflector 60 is in the closed position, the inner plate 62 is shielded inside the air duct 20 by the outer plate 61, and one side of the outer plate 61 in the width direction has a flange 622 bent toward the inner plate 62. In the aggregate blow-down mode, the inner panel 62 is closer to the splitter 50 and the cuff 622 is facing outward of the air chute 20. In the converging air supply mode, the inner plate 62 is closer to the splitter 50, and the flange 622 faces the outside of the air duct 20, so that the inner plate 62 and the outer plate 61 converge and guide the air flow twice, and the flange 622 promotes the convergence of the air flow in the central direction, thereby improving the convergence.

In some embodiments, the flow splitter 50 may be a column with a length direction perpendicular to the width direction of the outlet of the air duct 20, i.e., the length direction is perpendicular to the paper surface of the figures. The flow dividing member 50 is arranged to be rotatable about an axis parallel to the longitudinal direction thereof so as to adjust the sizes of the first and second

air blowing ports

11 and 12.

Referring to fig. 5 and 7, the cross-section of the shunt 50 can be made generally elliptical or oval. The axis of rotation of the shunt 50 may be through or near the center of the oval or olive shape. It is known that an ellipse or olive shape has a major axis and a minor axis. As shown in fig. 5, when the major axis of the oval or olive-shaped flow divider 50 extends substantially in the outlet width direction of the duct 20, the widths of the first and second blowing

ports

11 and 12 are the smallest; the first and second

air blowing openings

11 and 12 have the largest width when the major axis extends substantially perpendicular to the outlet width direction of the duct 20. In the embodiment of the utility model, the flow dividing piece 50 is set to be oval or olive-shaped, the distance between the flow dividing piece and the inner walls of the two sides of the width direction of the air duct 20 can be changed by rotating the fixed shaft, the air outlet area of the two air supply outlets can be adjusted, the structure is very simple, and a complex driving mechanism is not required to be arranged. Of course, other shapes for the splitter 50 are possible. For example, the flow splitter 50 is made in a non-cylindrical column shape. Alternatively, the splitter 50 can be cylindrical with an axis of rotation offset from the central axis. The above structure can also change the air outlet gap by rotating the flow divider 50 with a fixed axis.

The olive-shaped and the oval-shaped whole bodies are both formed by two convex curved surfaces, and the joint between the two large curved surfaces forms two tips. As shown in fig. 6, when the air conditioning indoor unit operates in the combined blowing mode, it is preferable that a convex curved surface faces the inside of the duct 20, and the convex curved surface smoothly disperses the airflow to the two lateral tips of the flow divider 50, that is, the two blowing ports. The other convex curved surface faces the outdoor environment, and the airflow at the two air supply openings can be guided to flow towards the center direction of the convex curved surface under the action of the coanda effect, so that the convergence of the two airflows is facilitated.

In some embodiments, as shown in fig. 1 to 7, the number of the wind tunnel 20, the flow divider 50, the wind guide plate 60 and the cover plate 15 may be two, and all are arranged side by side along the transverse direction of the cabinet 10. More specifically, the two air paths 20 may be made symmetrical with respect to a vertical plane extending back and forth. The splitter 50, the air deflector 60 and the cover plate 15 on both sides have the same shape, and the arrangement positions are symmetrical relative to the vertical plane. For the vertical air conditioner indoor unit shown in fig. 1 to 7, two air ducts 20 are provided, and the air supply mode of each air duct 20 can be independently controlled, so that the air supply angle range is wider, and the air supply adjusting mode is more.

Further, referring to fig. 1, the edge (a1, a2) of the outlet of each air duct 20 near the lateral side wall of the casing 10 may be positioned more rearward than the edge (B1, B2) near the lateral center of the casing 10, which makes the outlet of the air duct 20 open diagonally forward. The two first air supply outlets 11 are adjacent to each other and open forward, and the opening directions of the two second air supply outlets 12 are respectively inclined toward the two lateral sides, that is, the left second air supply outlet 12 is open toward the left front, and the right second air supply outlet 12 is open toward the right front. This makes the air supply angle range of the air conditioning indoor unit as a whole larger.

In some embodiments, the air conditioning indoor unit further includes an intermediate blower 30, and the intermediate blower 30 is located between the two ducts 20 and is configured to output the non-heat-exchange conditioned air flow toward the front. The air flow from the intermediate blower 30 may be a non-heat exchange air flow, such as a fresh air flow introduced from outside the room. Specifically, the middle blowing part 30 has a cylindrical structure, and introduces the outdoor fresh air flow and then outputs the fresh air flow to the outside through an orifice structure of the cylindrical wall. Of course, the intermediate blower 30 may also include a fan to facilitate the flow of fresh air. Alternatively, the air flow output from the intermediate blowing unit 30 may be air flow purified and filtered by the cleaning member inside the casing 10, or humidified air flow, or may be room air at room temperature.

The output airflow of the middle air supply part 30 and the outlet airflow of the two air ducts 20 converge at the outer side of the outlet of the air duct 20, and negative pressure is formed at the outlet of the two air ducts 20, so that the outflow of the airflow in the middle air supply part 30 can be driven, and the fan does not need to be frequently started or even omitted by the middle air supply part 30. Moreover, the air flows are mixed in advance outside the outlet of the air duct 20, and especially when the fresh air flow is blown out from the middle air supply part 30, the fresh air and the heat exchange air flow are mixed in advance, so that the indoor refreshing speed is higher.

In some embodiments, as shown in fig. 1 to 7, each cover plate 15 is slidably mounted to the casing 10 along the outer surface of the casing 10, and is reciprocally slidable between a first limit position and a second limit position to open the first and second blowing

ports

11 and 12 simultaneously or only one of them. In the first extreme position, the cover 15 fully opens the first and

second delivery ports

11, 12, as shown in figure 3. In the second extreme position, the cover 15 closes the first delivery opening 11 and opens the second delivery opening 12, as shown in figure 4. The cover plate 15 may be connected to the housing 10 by a motor and a rack and pinion mechanism to achieve reciprocating sliding thereof.

In the embodiment, the opening and closing of the two air supply outlets can be realized through the movement of the cover plate 15, and the structure is very simple. For example, in fig. 1, the first outlet 11 and the second outlet 12 are closed by a cover 15. As shown in fig. 2, the cover 15 closes the second supply port 12 and opens the first supply port 11. As shown in fig. 3, the cover 15 is opened to open the first and second

air blowing ports

11 and 12. As shown in fig. 4, the cover 15 opens only the second outlet 12 and closes the first outlet 11.

In the first extreme position, the cover 15 rests against the outside of the section of the casing 10 adjacent to the second delivery opening 12, i.e. against the outside of the lateral side walls of the casing 10, as shown in fig. 3. When one cover 15 (left cover) is in the second limit position and the other cover 15 (right cover) is in a position to completely close the first and

second blower ports

11 and 12, the end of the cover 15 (left cover) in the second limit position protrudes inside the other cover 15 (right cover), as shown in fig. 4. Further, when the two cover plates 15 are both in the position for closing the two air supply outlets, the end parts of the two cover plates 15 are connected, so that the appearance of the air-conditioning indoor unit is more attractive, as shown in fig. 1.

As shown in fig. 1, a cross-flow fan 80 is vertically disposed at the inlet of each air duct 20, and a heat exchanger 40 is disposed outside each cross-flow fan 80 and blocks the inlet of the air duct 20. The inlets of the two air ducts 20 may be arranged oppositely and inclined backwards, and the heat exchangers 40 on both sides are arranged obliquely, so as to form a V-shape with the opening facing backwards. The rear side of the housing 10 is provided with an air inlet so that the inlet air flow can be better distributed to the two heat exchangers 40. The indoor unit of the air conditioner may be an indoor unit of an air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. Under the action of the cross flow fan 80, indoor air flow enters the casing 10 through the air inlet, exchanges heat with the heat exchanger 40, is guided by the air duct 20, and is blown to the indoor environment through the air supply outlet to adjust the indoor environment air.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model.
