The utility model discloses do not restrict the style of machine in the air conditioning, can be wall-hanging, vertical, suspension type etc. and the embodiment of machine in the vertical air conditioning is illustrated in fig. 1 to 5.
Fig. 1 is a schematic structural view of an air conditioner indoor unit according to an embodiment of the present invention; fig. 2 is a schematic view of the indoor unit of the air conditioner shown in fig. 1 after the air guide 50 is moved forward by a certain distance; fig. 3 is a schematic view of the indoor unit of the air conditioner shown in fig. 2 when the air guide 50 is further advanced to close the polymeric duct 30. It should be noted that the drawings only illustrate some alternative air supply modes of the present invention, and some air supply modes are not explicitly listed.
As shown in fig. 1 to 3, an air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and a guide 50.
The casing 10 of 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 limiting an air outlet channel. The cabinet 10 defines at least one main duct 20 and a unified duct 30 adjacent thereto (inner walls of both sides of the unified duct 30 are B1C and B2D, respectively). The main air duct 20 has a main air supply outlet 11, the convergent air duct 30 has a convergent air supply outlet 12(CD), and both the main air supply outlet 11 and the convergent air supply outlet 12 are used for supplying air to the indoor environment, that is, the conditioned air generated by the indoor unit of the air conditioner is blown to the indoor environment through the main air supply outlet 11 and/or the convergent air supply outlet 12, so as to complete 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 main air duct 20 is provided with a bypass opening 21 (two bypass openings 21 are A1B1 and A2B2, respectively) to communicate with the converging air duct 30, so as to introduce the conditioned air flow of the main air duct 20 into the converging air duct 30. That is, the flow of the converging duct 30 originates from the main duct 20. At least the section of the polymerization air duct 30 adjacent to the polymerization air supply outlet 12 is tapered such that the air outlet cross section is gradually reduced along the air flow direction, for example, as shown in fig. 1, the whole section of the polymerization air supply outlet 12 is tapered.
The guiding element 50 is disposed in the converging air duct 30, and is used for guiding the air flow to the inner wall of the converging air duct 30, so that the air flow flows out through the gap between the guiding element 50 and the inner wall of the converging air duct 30, and converges at the outer side of the converging air outlet 12 under the guiding of the inner wall of the converging air duct 30.
Due to the addition of the diversion piece 50, in the process of adjusting the forward flow of the air flow, the rear surface of the diversion piece 50 is guided to respectively flow to the two sides of the diversion piece 50 and respectively flow to the gap formed by the diversion piece 50 and the inner wall of the polymerization air duct 30, so that the air outlet speed is higher. And because the section of the polymerization air supply outlet 12 adjacent to the polymerization air supply outlet 12 is in a tapered shape, each air flow gradually converges towards the air flow center direction in the outward flowing process to form 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
The utility model discloses machine in air conditioning both accessible main supply-air outlet 11 realizes conventional air supply, can realize polymerization air supply through polymerization supply-air outlet 12 again, and the air supply mode is more diversified, possess multiple air supply mode to the different demands of the different conditions of fully provided user, make user's wind sense experience better.
In the embodiment shown in fig. 1 to 5, the casing 10 extends in a vertical column shape, that is, the air-conditioning indoor unit is a vertical air-conditioning indoor unit. The main air duct 20, the main air supply outlet 11, the polymerization air duct 30 and the polymerization air supply outlet 12 are all vertical bars. The deflector 50 has a vertically extending cylindrical shape. 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 is a long strip extending horizontally in the length direction, and the main air duct, the main air supply outlet, the polymerization air duct and the polymerization air supply outlet are correspondingly long strips extending horizontally and transversely, which will not be described in detail.
In some embodiments, as shown in fig. 1-3, the baffle 50 is configured to translate in a direction toward or away from the polymeric blower outlet 12 to adjust its spacing from the inner wall of the polymeric duct 30. For example, the baffle 50 of FIG. 2 is closer to the converging air outlet 12 than in FIG. 1, making it less spaced from the inner wall of the converging air duct 30. In the embodiment, the distance between the diversion piece 50 and the inner wall of the polymerization air duct 30 is adjusted by translating the diversion piece, so that the air quantity of the polymerization air supply can be adjusted. Further, the diversion member 50 can also close the converging air duct 30. For example, as shown in fig. 3, the baffle 50 may be further translated into contact with the inner wall of the converging air duct 30 to close the converging air duct 30, i.e., to adjust the converging air supply volume to zero. The diversion element 50 can be driven to translate by a motor and a rack-and-pinion mechanism, and the detailed structure is not described again.
So, make the utility model discloses air supply regulation mode of machine in air conditioning is very abundant, and the machine in the air conditioning of being convenient for adjusts different air supply modes according to the difference of operating condition and the difference of user's demand. For example, as shown in fig. 1, the polymerization air blowing port 12 and the main air blowing port 11 may be both opened to perform normal air blowing and polymerization air blowing at the same time. Alternatively, as shown in FIG. 2, the deflector 50 is translated to turn down the collective air supply. Alternatively, as shown in fig. 3, the polymerization air supply port 12 is closed and air is supplied completely from the main air supply port 11.
An air guide device 60 may be provided at the main air blowing port 11 to guide the air blowing direction of the main air blowing port 11. For example, as shown in fig. 1 to 3, the air guiding device 60 may be a guide vane.
In some embodiments, the flow guiding member 50 may be a column having a length direction perpendicular to the width direction of the polymerization air blowing port 12, that is, a length direction perpendicular to the paper surface direction of the drawings. The cross-section of the baffle member 50 is generally oval or olive-shaped. It will be appreciated that the ellipse or olive shape has two points (a, b) and two convex curved surfaces 51, 52. The two tips (a, B) face the inner walls (B1C, B2C) of the converging air duct 30, and an outer convex curved surface 51 faces the converging air outlet 12. When the flow guide 50 moves to make the two tips (a, b) thereof respectively abut against the two side inner walls of the polymerization air duct 30, the flow guide 50 closes the polymerization air duct 30, as shown in fig. 3. Since the convex curved surface 52 faces the inside of the converging air duct 30, the air flow can be smoothly dispersed to two lateral tips of the flow guide 50, that is, two gaps formed between the flow guide 50 and the converging air duct 30. The other convex curved surface 51 faces the outdoor environment, and the airflow on the inner walls of the two sides of the converging air duct 30 can be guided to flow along the surface of the convex curved surface 51 towards the center direction under the action of the coanda effect, so that the convergence of the two airflows is facilitated.
Fig. 4 is a schematic view of an indoor unit of an air conditioner according to another embodiment of the present invention; fig. 5 is a schematic view of the air conditioning indoor unit shown in fig. 4 after the damper 70 is opened.
As shown in fig. 4 and 5, in some embodiments, a damper 70 is disposed at each bypass opening 21, and the damper 70 is configured to controllably open and close the bypass opening 21. When the damper 70 opens the bypass opening 21, the airflow in the main duct 20 is allowed to enter the converging duct 30, and the converging air supply is performed. On the contrary, when the damper 70 closes the bypass opening 21, the airflow in the main duct 20 cannot enter the collective air duct 30, and the collective air supply is not performed.
In an alternative, as shown in fig. 4 and 5, the damper 70 is pivotably mounted to one side of the bypass opening 21 to rotatably open and close the bypass opening 21. The damper 70 may be driven to rotate by a motor. Further, the damper 70 may be configured to be rotatable to a position for shielding the main duct 20 after opening the bypass opening 21. Specifically, the pivot end of the damper 70 is connected to the side of the bypass opening 21 near the downstream. Thus, after the air door 70 opens the bypass opening 21, the main air duct 20 is closed, so that the air flow completely enters the converging air duct 30, and the converging air outlet volume is larger.
In some alternative embodiments, the damper 70 may also be made to translatably open and close the bypass opening 21, and the detailed structure will not be described.
In some embodiments, the number of the main air ducts 20 is two, and the polymeric air duct 30 is disposed between the two main air ducts 20. For example, as shown in fig. 1 to 5, in the case of an indoor unit of an upright air conditioner, the casing 10 is in a vertically extending column shape, and preferably, two main ducts 20 are arranged in a lateral direction of the casing 10 (the lateral direction is indicated in the figure), and both the main air blowing ports 11 and the collective air blowing port 12 are open forward. In the present embodiment, two main air ducts 20 are provided, and the air supply mode of each main air duct 20 can be independently controlled, which makes the air supply angle range larger and the air supply adjustment mode more.
As shown in fig. 1, a cross-flow fan 80 may be disposed at an inlet of each main air duct 20, the indoor unit of an air conditioner further includes a heat exchanger 40, the heat exchanger 40 is located behind the two cross-flow fans 80, and two lateral sides of the heat exchanger 40 are bent forward, so that two edges of the heat exchanger respectively abut against inner walls of the two main air ducts 20. An air inlet (not shown) of the casing 10 is opened on the rear wall of the casing 10, and under the action of the cross flow fan 80, the indoor air flow enters the casing 10 from the air inlet, exchanges heat with the heat exchanger 40, and then enters the two main air ducts 20. Because the heat exchanger 40 has completely blocked the inlets of the two main air ducts 20, the heat exchange air flow completely enters the two main air ducts 20, and the air quantity waste is avoided.
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.
