Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and specifically provides an indoor air conditioning unit. Background Technology

[0002] In the existing technology, air conditioning indoor units, as important devices for regulating indoor temperature, humidity and air circulation, have been widely used in various places.

[0003] Traditional air conditioner indoor units typically use straight or simple curved air deflectors. While straight deflectors are simple in structure, they have limitations in guiding airflow direction and range, failing to adequately meet the diverse needs of different spatial layouts and users regarding airflow direction. For example, in larger indoor spaces, straight deflectors struggle to evenly distribute airflow to all corners, easily leading to uneven indoor temperature distribution.

[0004] While simple curved air guides improve airflow diffusion to some extent, their adjustment capabilities are still insufficient for some special air supply needs, such as when airflow needs to be precisely directed to a specific area or to achieve a specific airflow distribution pattern. Utility Model Content

[0005] One objective of this invention is to solve the problem of poor airflow guiding effect of the air guide plate in existing air conditioning indoor units.

[0006] To achieve the above objectives, this utility model provides an indoor air conditioning unit, comprising:

[0007] A housing configured to be mounted on a wall, the housing defining an air outlet duct with the air outlet of the air outlet duct located at the lower front part of the housing;

[0008] A V-shaped air guide plate is rotatably mounted on the housing and includes a first air guide plate segment and a second air guide plate segment. The rotation axis of the V-shaped air guide plate is located at the junction of the first air guide plate segment and the second air guide plate segment. The included angle between the first air guide plate segment and the second air guide plate segment is β, where 90°≤β<180°.

[0009] The first motor is used to drive the V-shaped air guide plate to rotate around the rotation axis, so as to change the posture of the V-shaped air guide plate and thus realize different air supply modes of the indoor unit of the air conditioner.

[0010] Optionally, the rotation axis is located in front of and below the air outlet, and at least one of the first and second air guide plate segments can be rotated to a position aligned with the lower end of the air outlet to extend the air outlet duct through the V-shaped air guide plate; 130°≤β≤160°, so as to reduce the wind resistance of the V-shaped air guide plate while the V-shaped air guide plate can change the airflow direction.

[0011] Optionally, 140°≤β≤150°.

[0012] Optionally, when the first guide plate segment is rotated to a position aligned with the lower end of the air outlet, it engages with or abuts against the bottom wall of the air outlet; and / or, when the second guide plate segment is rotated to a position aligned with the lower end of the air outlet, it engages with or abuts against the bottom wall of the air outlet.

[0013] Optionally, the first diversion plate segment and the second diversion plate segment have a smooth transition to reduce the obstruction of airflow at the junction of the first diversion plate segment and the second diversion plate segment.

[0014] Optionally, at least one of the first drainage plate segment and the second drainage plate segment is configured as an arc-shaped plate.

[0015] Optionally, the concave side of the arc-shaped plate is located inside the V-shaped air guide plate.

[0016] Optionally, the first motor is a self-locking motor to prevent the V-shaped air guide plate from rotating under the action of airflow.

[0017] Optionally, the indoor unit of the air conditioner further includes an arc-shaped air guide plate located above the V-shaped air guide plate and a second motor for driving the arc-shaped air guide plate to rotate.

[0018] Optionally, the arc-shaped air guide plate and the V-shaped air guide plate can be rotated to a position where they are both tilted downwards and interfere with each other in the extension direction of the air outlet duct, so that the airflow blown from the air outlet blows downwards towards the air conditioner indoor unit.

[0019] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by configuring a V-shaped air guide plate for the indoor unit of the air conditioner, and positioning the rotation axis of the V-shaped air guide plate at the junction of the first and second air intake plate sections, the V-shaped air guide plate can rotate around this rotation axis when driven by the first motor, thereby changing the posture of the V-shaped air guide plate and realizing different air supply modes of the indoor unit of the air conditioner. The V-shaped structure of the V-shaped air guide plate can concentrate the airflow flowing through its inner side and blow it further, while making the airflow flowing through its outer side more dispersed and blow it more evenly. Therefore, the V-shaped air guide plate of this utility model has a better air guiding effect than existing straight and arc-shaped air guide plates.

[0020] Furthermore, by positioning the rotation axis of the V-shaped air guide plate below and in front of the air outlet, and by allowing at least one of the first and second air guide plate sections to rotate to a position aligned with the lower end of the air outlet, the V-shaped air guide plate extends the air outlet duct, reduces wind resistance, and increases the air volume delivered by the indoor unit of the air conditioner.

[0021] Furthermore, by making the transition between the first and second airflow deflector sections smooth, the obstruction of airflow at the junction of the first and second airflow deflector sections is reduced, thereby reducing the wind noise when the indoor unit of the air conditioner is working.

[0022] Other beneficial effects of this utility model will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand the improvement purpose, features and advantages of this utility model. Attached Figure Description

[0041] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0042] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the corresponding device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0044] Furthermore, it should be noted that in the description of this utility model, the terms "coldness" and "heat" are two descriptions of the same physical state. That is, the higher the "coldness" of a target object (e.g., evaporator, air, condenser, etc.), the lower its "heat," and vice versa. A target object absorbs "coldness" while releasing "heat," and releases "coldness" while absorbing "heat." A target object retains "coldness" or "heat" to maintain its current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon; that is, a target object (e.g., evaporator) absorbs heat while refrigerating.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the indoor unit 001 of the air conditioner includes a housing 110, a heat exchanger 120, a fan 130, a V-shaped air guide plate 210, a first motor 220, an optional arc-shaped air guide plate 310, and an optional second motor 320.

[0046] like Figure 1 As shown, in some embodiments of this utility model, the housing 110 is configured to be mounted on a wall, that is, the indoor air conditioner 001 of this utility model can be a wall-mounted indoor air conditioner 001. The housing 110 is provided with an air inlet 111 and an air outlet duct 112 communicating with the air inlet 111. The air inlet 111 can be located on the top side of the housing 110, the air outlet duct 112 is formed inside the housing 110, and the air outlet 1121 of the air outlet duct 112 is located at the lower front part of the housing 110.

[0047] In addition, in other embodiments of this utility model, those skilled in the art can also, as needed, set the air inlet 111 at other locations on the housing 110, for example, set at least a portion of the air inlet 111 at the top of the front side of the housing 110.

[0048] Continue reading Figure 1In some embodiments of this utility model, the heat exchanger 120 is installed inside the housing 110 and located between the air inlet 111 and the air outlet duct 112 to heat or cool the air flowing from the air inlet 111 to the air outlet duct 112.

[0049] Those skilled in the art will understand that the indoor unit 001 of an air conditioner is generally used in conjunction with the outdoor unit (not shown in the figure) to form a complete refrigerant circulation system. A complete refrigerant circulation system generally includes a compressor, condenser, electronic expansion valve and / or capillary tube, evaporator, etc.

[0050] Those skilled in the art will understand that when the indoor unit 001 of the air conditioner is cooling, the heat exchanger 120 is used as an evaporator to cool the air inside the casing 110. When the indoor unit 001 of the air conditioner is heating, the heat exchanger 120 is used as a condenser to heat the air inside the casing 110.

[0051] Continue reading Figure 1 In some embodiments of this utility model, the fan 130 can be a cross-flow fan 130 and is installed inside the housing 110 to drive air from the air inlet 111 to the air outlet duct 112.

[0052] like Figure 1 and Figure 2 As shown, the V-shaped air guide plate 210 is rotatably mounted on the housing 110 and includes a first air guide plate section 211 and a second air guide plate section 212. The rotation axis 213 of the V-shaped air guide plate 210 is located at the junction of the first air guide plate section 211 and the second air guide plate section 212.

[0053] For example, the V-shaped air guide plate 210 has two rotating shafts at both ends along the axial direction of the rotation axis 213. The housing 110 is provided with insertion holes adapted to these rotating shafts. The rotating shafts are inserted into these insertion holes, thereby mounting the V-shaped air guide plate 210 onto the housing 110.

[0054] like Figure 2 As shown, the included angle between the first guide plate segment 211 and the second guide plate segment 212 is β, 90°≤β<180°, to ensure that the V-shaped air guide plate 210 has a V-shaped structure and to avoid increasing the airflow resistance due to the small included angle between the first guide plate segment 211 and the second guide plate segment 212.

[0055] from Figure 1 As can be seen from this, in some embodiments of the present invention, the rotation axis 213 is located in front of and below the air outlet 1121, and at least one of the first guide plate segment 211 and the second guide plate segment 212 can be rotated to a position aligned with the lower end of the air outlet 1121, so as to extend the air outlet duct 112 through the V-shaped air guide plate 210.

[0056] Furthermore, 130°≤β≤160°, so that while the V-shaped air guide 210 can change the airflow direction, the wind resistance of the V-shaped air guide 210 is reduced.

[0057] Preferably, 140°≤β≤150°.

[0058] Based on the foregoing description, in some embodiments of this utility model, β can specifically be 90°, 130°, 135°, 140°, 145°, 150°, 158°, 160°, 172°, etc.

[0059] like Figure 2 As shown, the first motor 220 is used to drive the V-shaped air guide plate 210 to rotate around the rotation axis 213, so as to change the posture of the V-shaped air guide plate 210, thereby realizing different air supply modes of the indoor unit 001 of the air conditioner (such as... Figure 1 , Figures 3 to 12 (As shown).

[0060] In some embodiments of this utility model, the first motor 220 and the V-shaped air guide plate 210 can be directly driven and connected, or they can be connected through other transmission mechanisms.

[0061] As an example, the housing of the first motor 220 is fixedly mounted on the housing 110, the shaft of the first motor 220 is circumferentially fixedly connected to the V-shaped air guide plate 210, and the shaft of the first motor 220 is coaxial with the rotation axis 213 of the V-shaped air guide plate 210.

[0062] As an example two, the housing of the first motor 220 is fixedly mounted on the housing 110, and the shaft of the first motor 220 is connected to the V-shaped air guide plate 210 by a reducer.

[0063] Furthermore, the first motor 220 can be a self-locking motor to prevent the V-shaped air guide plate 210 from rotating under the action of airflow, thereby ensuring that the position of the V-shaped air guide plate 210 remains basically unchanged under different air supply modes, thus ensuring the reliability of the air supply mode of the indoor unit 001 of the air conditioner.

[0064] Furthermore, the first motor 220 can also be a stepper motor to ensure that the V-shaped air guide plate 210 can rotate accurately. Figure 1 , Figures 3 to 12 The location shown.

[0065] like Figure 1 As shown, in some embodiments of this utility model, when the first guide plate segment 211 is rotated to a position aligned with the lower end of the air outlet 1121, it can be fitted or abutted against the bottom wall of the air outlet 1121 to extend the air supply duct.

[0066] Correspondingly, when the second diversion plate section 212 is rotated to a position aligned with the lower end of the air outlet 1121, it can also be fitted or abutted against the bottom wall of the air outlet 1121.

[0067] Furthermore, those skilled in the art can also make the transition between the first diversion plate segment 211 and the second diversion plate segment 212 smooth as needed, so as to reduce the obstruction effect of the connection between the first diversion plate segment 211 and the second diversion plate segment 212 on the airflow.

[0068] For example, a rounded chamfer is provided between the first drainage plate segment 211 and the second drainage plate segment 212.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the arc-shaped air guide plate 310 is located above the V-shaped air guide plate 210, and the second motor 320 is used to drive the arc-shaped air guide plate 310 to rotate.

[0070] For example, the arc-shaped air guide plate 310 has a plate-like structure or a rod-like structure at both ends along its length. A rotating shaft is provided on the plate-like structure or rod-like structure, and a shaft hole adapted to the rotating shaft is provided on the housing 110. The rotating shaft of the arc-shaped air guide plate 310 is rotatably inserted into the shaft hole, thereby optionally mounting the arc-shaped air guide plate 310 onto the housing 110.

[0071] The connection method between the second motor 320 and the arc-shaped air guide plate 310 can be referred to the previous description of the first motor 220 and the V-shaped air guide plate 210.

[0072] like Figures 7 to 12 As shown, in some embodiments of this utility model, the arc-shaped air guide plate 310 and the V-shaped air guide plate 210 can be rotated to a position where they are both tilted downwards and interfere with each other in the extension direction of the air outlet duct 112, so that the airflow blown out from the air outlet 1121 blows towards the lower part of the air conditioner indoor unit 001.

[0073] like Figure 1 , Figures 3 to 12 As shown, in some embodiments of this utility model, the combination of the V-shaped air guide plate 210 and the arc-shaped air guide plate 310 can enable the air conditioner indoor unit 001 to have six air supply modes.

[0074] like Figure 1 and Figure 3 As shown, in the first air supply mode, the V-shaped air guide plate 210 and the arc-shaped air guide plate 310 provide minimal obstruction to the airflow, resulting in the maximum air volume in this mode. This air supply mode can be applied to both cooling and heating of the indoor unit 001 of the air conditioner.

[0075] like Figure 4 and Figure 5As shown, in the second air supply mode, the V-shaped air guide plate 210 and the arc-shaped air guide plate 310 can guide the airflow to the front and upper part of the air conditioner indoor unit 001 and siphon in a portion of the ambient air. This air supply mode can be applied to the cooling of the air conditioner indoor unit 001.

[0076] like Figure 6 As shown, in the third air supply mode, the V-shaped air guide plate 210 and the arc-shaped air guide plate 310 can guide the airflow to the front and lower part of the air conditioner indoor unit 001 and siphon in some ambient air. This air supply mode can be used for cooling of the air conditioner indoor unit 001. It is especially suitable for air conditioner indoor units 001 installed at the head of beds, as it can prevent cold air from blowing directly on the user's head.

[0077] like Figure 7 and Figure 8 As shown, in the fourth air supply mode, the V-shaped air guide plate 210 and the arc-shaped air guide plate 310 can guide the airflow to the area below the indoor unit 001. This air supply mode can be used for cooling of the indoor unit 001. It is especially suitable for indoor units 001 installed at the foot of the bed, as it can prevent cold air from blowing directly on the user's head.

[0078] like Figure 9 and Figure 10 As shown, in the fifth air supply mode, the V-shaped air guide plate 210 and the arc-shaped air guide plate 310 allow the airflow to be blown downwards along their surfaces, preventing the air from blowing directly onto the user. This air supply mode can be applied to the heating or cooling of the indoor unit 001 of the air conditioner.

[0079] like Figure 11 and Figure 12 As shown, in the sixth air supply mode, the V-shaped air guide plate 210 and the arc-shaped air guide plate 310 can cause the airflow to blow downwards along their surfaces, and can also cause the airflow to blow downwards along the wall, avoiding direct airflow to the user. This air supply mode can be applied to the heating or cooling of the indoor unit 001 of the air conditioner.

[0080] It should be noted that, in Figure 3 , Figure 5 , Figure 8 , Figure 10 and Figure 12 In the simulated air supply diagram shown, the lighter the color, the faster the airflow velocity.

[0081] Furthermore, in other embodiments of this utility model, those skilled in the art can, as needed, configure at least one of the first guide plate segment 211 and the second guide plate segment 212 as an arc-shaped plate, and the concave side of the arc-shaped plate is located inside the V-shaped air guide plate 210 (e.g., Figure 2 (as shown), to increase the guiding angle of the V-shaped air guide plate 210 for the airflow.

[0082] In addition, in other embodiments of this utility model, those skilled in the art may omit the arc-shaped air guide plate 310 and the second motor 320 as needed.

[0083] Based on the foregoing description, those skilled in the art will understand that the V-shaped air guide plate 210 of this utility model has a good air guiding effect, enabling the indoor unit 001 of the air conditioner to have more air supply modes and improving the user experience.

[0084] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.

[0085] Finally, it should be noted that in this invention, the term "connection" refers to fluid communication, allowing fluid (e.g., air, liquid) to flow between two interconnected entities. Furthermore, this "connection" can be either a leak-free flow of fluid between two interconnected entities, or a flow with slight leakage between two interconnected entities.
