Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit and its air guiding device. Background Technology

[0002] With the development of air conditioning technology, the appearance and functions of wall-mounted air conditioner indoor units are constantly being updated, and various new technologies are emerging one after another.

[0003] However, there are very few innovative airflow design features for wall-mounted air conditioner indoor units. Existing solutions typically involve installing an air guide vane and swivel blades at the air outlet. The air guide vane adjusts the vertical angle of the outlet, while the swivel blades provide horizontal airflow. The widespread use of this airflow design in existing wall-mounted air conditioner indoor units results in a uniform user experience and product appearance, hindering the enhancement of product quality.

[0004] Therefore, how to innovate in air guiding structure has become a technical problem that the air conditioning industry urgently needs to solve. Summary of the Invention

[0005] One object of the present invention is to provide a novel air guiding device and an indoor air conditioning unit having the same, so as to improve product differentiation and user experience.

[0006] A further objective of this invention is to enable the indoor unit of the air conditioner to select different air supply modes as needed.

[0007] On one hand, the present invention provides an air guiding device for installation at the air outlet of an indoor air conditioning unit, characterized in that it includes:

[0008] Two end plates, which can rotate about an axis parallel to their normal direction, are spaced apart along their normal direction;

[0009] Multiple air guide sections, each with its two ends connected to two end plates, are arranged circumferentially along the end plates so that when the end plates are rotated to an angle where a particular air guide section is opposite the air outlet, air is guided by that air guide section; and

[0010] A first motor, connected to one of the end plates, is used to drive its rotation.

[0011] Optionally, when the air guides are arranged sequentially along the circumference of the end plate, the circumferential angle occupied by them on the end plate is less than 360°, so as to form an open side for air intake.

[0012] Optionally, the plurality of air guides include an air guide plate, a first grille plate, and / or a second grille plate; wherein the grille bars of the first grille plate and the second grille plate extend in different directions;

[0013] The air guide plate can rotate around an axis parallel to the normal of the end plate to guide the air outlet direction.

[0014] Optionally, the air guide device further includes a second motor mounted on one of the end plates for driving the air guide plate to rotate.

[0015] Optionally, the plurality of air guides include the first grille and the second grille;

[0016] Each of the end plates has a first groove formed on its inner side to allow both ends of the first grid plate to be slidably disposed therein; and / or

[0017] Each of the end plates has a second groove formed on its inner side to allow the two ends of the second grid plate to be slidably disposed therein.

[0018] Optionally, the air guide device is configured such that the first grille and the second grille overlap or partially overlap at the air outlet.

[0019] Optionally, both the first and second slide grooves are annular grooves whose centers fall on the rotation axis of the end plate; and

[0020] Both the first and second grating plates are curved plates.

[0021] Optionally, each of the end plates is circular.

[0022] On the other hand, the present invention also provides an indoor air conditioning unit, characterized in that it includes:

[0023] The casing has an air outlet; and

[0024] The air guiding device as described in any of the above is disposed at the air outlet, and the first motor is mounted on the housing.

[0025] Optionally, the indoor unit of the air conditioner is a wall-mounted indoor unit, the air outlet is a long strip extending horizontally, and the rotation axes of the two end plates are parallel to the length direction of the air outlet.

[0026] In the air conditioner indoor unit and its air guiding device of the present invention, multiple air guiding sections are arranged between two end plates. These multiple air guiding sections can have different forms, such as air guiding plates, first grilles, and second grilles. The two end plates are rotatable. Thus, when the end plates are rotated to an angle where a certain air guiding section is opposite the air outlet, air is guided by that air guiding section, forming an air guiding mode. When it is necessary to switch the air guiding mode, the end plates can be rotated, and air is guided by other air guiding sections, forming another air guiding mode. This invention adjusts the air guiding mode and changes the air guiding effect by rotating the end plates. Its novel and ingenious structure makes the air conditioner product more distinctive. Furthermore, it revolutionizes the appearance of the air conditioner indoor unit, making the product more upscale and providing a better user experience.

[0027] Furthermore, in the indoor unit of the air conditioner of the present invention, when the air guides are arranged sequentially along the circumference of the end plate, the circumferential angle occupied by them on the end plate is less than 360°, so as to form an open side for air intake. In this way, it is avoided that the air guides form a closed cylindrical space, which would lead to poor airflow.

[0028] Furthermore, in the air conditioner indoor unit and its air guiding device of the present invention, the first grille and the second grille are overlapped or partially overlapped at the air outlet, that is, the first grille and the second grille act on the airflow successively. Since the extension directions of the grille bars of the two grilles are different, a plurality of grid-like spaces are formed between them, thus creating a micro-perforated air outlet effect.

[0045] One embodiment of the present invention provides an air guiding device 50, which is installed at the air outlet 12 of the indoor unit of an air conditioner to guide the airflow direction at the air outlet 12. The indoor unit of the air conditioner described in this embodiment is the indoor part of an air conditioner, used to regulate indoor air, such as cooling / heating, dehumidifying, purifying, and introducing fresh air. The present invention does not limit the style of the indoor unit; it can be wall-mounted, floor-standing, ceiling-mounted, etc. Figures 1 to 11 The illustration shows an example of a wall-mounted air conditioner indoor unit; examples of other types of air conditioner indoor units will not be described in detail.

[0046] Figure 1 This is a schematic diagram of the structure of an air conditioner indoor unit according to an embodiment of the present invention; Figure 2 yes Figure 1 The enlarged cross-sectional view of the indoor unit of the air conditioner shown is when the first grille plate 52 is used to guide the airflow.

Figure 7 yes Figure 6 Another angle view of the air guide device 50; Figure 8 yes Figure 2 The diagram shows the indoor unit of the air conditioner using the air guide plate 51 for forward airflow. Figure 9 yes Figure 8 Another angle view of the air guide device 50; Figure 10 yes Figure 2 The diagram shows the indoor unit of the air conditioner using the air guide plate 51 for downward airflow. Figure 11 yes Figure 2 The diagram shows the indoor unit of the air conditioner when the air outlet 12 is closed using the air guide plate 51. The arrows in the diagram indicate the direction of airflow.

[0047] like Figures 1 to 11As shown, the air guiding device 50 of this embodiment of the invention is used to install at the air outlet 12 of the indoor unit of an air conditioner. It generally includes two end plates 57 and 58 and multiple air guiding sections 51, 52, and 53. The two end plates 57 and 58 are rotatable about an axis x1 parallel to their normal direction (x-direction), and are spaced apart along their normal direction. The normal direction of the end plate refers to the direction perpendicular to the large plane of the plate. The two end plates 57 and 58 can be arranged in parallel.

[0048] Each air guide section 51, 52, 53 is connected to two end plates 57, 58 at both ends, and multiple air guide sections 51, 52, 53 are arranged circumferentially along the end plates 57, 58 so that when the end plates 57, 58 are rotated to an angle that makes a certain air guide section 51, 52, 53 opposite to the air outlet 12, the air guide section 51, 52, 53 will guide the air.

[0049] First motor 55 (reference) Figure 4 (Position schematic) is connected to an end plate 58 for driving its rotation, that is, driving it to rotate around x1. The first motor 55 can be a stepper motor. The first motor 55 can be electrically connected to the controller of the indoor unit of the air conditioner so that it can be controlled by the controller.

[0050] In the air conditioner indoor unit and its air guiding device 50 of this embodiment, a plurality of air guiding sections 51, 52, and 53 are provided between two end plates 57 and 58. The forms of the plurality of air guiding sections 51, 52, and 53 can be different; for example, the plurality of air guiding sections 51, 52, and 53 can be air guide plates 51, first grille plates 52, and second grille plates 53. The two end plates 57 and 58 are rotatable. Thus, when the end plates 57 and 58 rotate to an angle where a certain air guiding section 51, 52, or 53 is opposite to the air outlet 12, air is guided by that air guiding section 51, 52, or 53, forming an air guiding mode. When it is necessary to switch the air guiding mode, the end plates 57 and 58 can be rotated, and air is guided by other air guiding sections 51, 52, and 53, forming another air guiding mode. For example… Figures 2 to 5 As shown, the first grille plate 52 guides the airflow, allowing it to be directed to the left or right. Figures 6 to 7 As shown, the first grille plate 52 and the second grille plate 53 work together to guide the airflow, making the airflow finer and achieving a gentle breeze effect. Figure 8 and Figure 9 As shown, the air guide plate 51 guides the airflow forward, changing the vertical direction of the airflow so that it blows forward or upward to meet the needs of the cooling mode. Figure 10 As shown, the airflow is guided downwards by the air guide plate 51, allowing the airflow to better reach the ground and meet the needs of the heating mode. Figure 11 As shown, the air outlet 12 is closed by the air guide plate 51. When the indoor unit of the air conditioner is stopped and running, the air outlet 12 can be closed by the air guide plate to prevent dust and other impurities from entering the housing 10 through the air outlet 12.

[0051] This invention adjusts the airflow pattern and changes the airflow effect by rotating end plates 57 and 58. Its novel and ingenious structure makes the air conditioner more distinctive. Moreover, it revolutionizes the appearance of the air conditioner indoor unit, making the product more upscale and providing a better user experience.

[0052] In some embodiments, please refer to Figure 3 and Figure 7 When the air guides 51, 52, and 53 are arranged sequentially along the circumference of the end plates 57 and 58, the circumferential angle occupied by them on the end plates 57 and 58 is less than 360°, so as to form an open side for air intake. In other words, it avoids the air guides 51, 52, and 53 forming a closed cylindrical space, which would cause poor airflow.

[0053] Specifically, such as Figures 2 to 11 As shown, each end plate 57 and 58 is circular. Each air guide section 51, 52, and 53 can be an arc-shaped plate to accommodate the circular end plates 57 and 58.

[0054] In some embodiments, the aforementioned plurality of air guide components include an air guide plate 51, a first grille plate 52, and / or a second grille plate 53. That is, it may include at least one of them, any two, or all three. For example... Figures 1 to 11 In the illustrated embodiment, each air guide includes an air guide plate 51, a first grille plate 52, and a second grille plate 53.

[0055] The first grille 52 and the second grille 53 have different extending directions of their grille bars to guide airflow in different directions, creating differentiation. For example, the length direction of the grille bars of the first grille 52 can be perpendicular to the axial direction x of the end plates 57 and 58, and the length direction of the grille bars of the second grille 53 can be parallel to the axial direction x of the end plates 57 and 58. The air guide plate 51 can rotate about an axis x2 parallel to the normal direction of the end plates 57 and 58 to guide the airflow direction of the air outlet 12. The air guide device 50 also includes a second motor 512 (see...). Figure 4 (Illustration shown) The second motor 512 is mounted on an end plate 57, 58 to drive the air guide plate 51 to rotate.

[0056] When the indoor unit of the air conditioner is a wall-mounted air conditioner, the first grille 52 can be used to guide the air to the left or right, the second grille 53 can be used to guide the air to the top, front or bottom, and the air guide plate 51 can be used to change the vertical air guiding angle, that is, the pitch angle of the air outlet.

[0057] In addition, the air guiding device 50 may also include other forms of air guiding parts 51, 52, 53, such as micro-perforated plates, etc. In addition, the air guiding plate 51 may also be provided with a set of sway vanes to guide the lateral air outlet direction; these derivative structures will not be described in detail here.

[0058] In some embodiments of the present invention, such as Figures 1 to 11 As shown, multiple air guide components include a first grille plate 52 and a second grille plate 53. A first groove 581 is formed on the inner surface of each end plate 57, 58 to allow the two ends of the first grille plate 52 to be slidably disposed therein. A second groove 582 is formed on the inner surface of each end plate 57, 58 to allow the two ends of the second grille plate 53 to be slidably disposed therein. Thus, the positions of the first grille plate 52 and the second grille plate 53 can not only change with the rotation of the end plates 57, 58, but can also be changed by sliding within the first groove 581 or the second groove 582, resulting in a very ingenious structure and greater positional adjustability. Both the first groove 581 and the second groove 582 are annular grooves whose centers fall on the rotation axis of the end plates 57, 58, and both the first grille plate 52 and the second grille plate 53 are arc-shaped plates to facilitate smoother sliding within them.

[0059] like Figure 6 and Figure 7 As shown, the air guiding device 50 is configured such that the first grille plate 52 and the second grille plate 53 overlap or partially overlap at the air outlet 12, that is, the first grille plate 52 and the second grille plate 53 act on the airflow sequentially. Because the grille bars of the two grille plates extend in different directions, a plurality of grid-like spaces are formed between them, thus creating a micro-perforated air outlet effect.

[0060] Another embodiment of the present invention provides an indoor unit for an air conditioner. For example... Figure 1 As shown, an indoor air conditioning unit may generally include a housing 10 and an air guide device 50 as described above.

[0061] The housing 10 defines a space for accommodating the various components of the wall-mounted air conditioner indoor unit, and an airflow for regulating the indoor environment is formed inside the housing 10. Examples include cold air in cooling mode, hot air in heating mode, and fresh air in fresh air mode. The housing 10 has an air outlet 12 for drawing out the airflow from within the housing 10. A motor is mounted on the housing.

[0062] Air conditioner indoor units can take various forms, such as Figures 1 to 11 As shown, the indoor unit of the air conditioner is a wall-mounted air conditioner. The air outlet 12 is a long strip that extends horizontally. The rotation axes of the two end plates 57 and 58 are parallel to the length direction of the air outlet 12.

[0063] like Figure 2As shown, in this embodiment of the invention, the wall-mounted air conditioner indoor unit can be the indoor part of a split wall-mounted room air conditioner that uses a vapor compression refrigeration cycle system for cooling / heating. The housing 10 contains a heat exchanger 30 and a fan 40. The heat exchanger 30, the throttling device, and the compressor, condenser, and other refrigeration components located in the outdoor unit of the air conditioner are connected via pipes to form a vapor compression refrigeration cycle system. Under the action of the fan 40, indoor air enters the interior of the housing 10 through the air inlet at the top of the housing 10, undergoes forced convection heat exchange with the heat exchanger 30, forming heat exchange air, which is then blown towards the outlet of the air duct under the guidance of the air duct, and then blown into the indoor environment through the air outlet 12, thus regulating the indoor air environment. The fan 40 is preferably a cross-flow fan, which is located at the inlet of the air duct. The heat exchanger 30 is preferably a three-stage heat exchanger.

[0064] In the description of this embodiment, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0065] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
