[0002] Air conditioner indoor unit as the important equipment of adjusting indoor temperature, humidity and air circulation, has been widely applied in various places.

[0003] The existing air conditioner indoor unit, in order to realize the uniform distribution of indoor temperature and adjust air supply direction, air deflector is generally arranged at the air outlet of air conditioner indoor unit. These air deflectors are generally provided as flat plate shape, and are driven by motor to rotate around a fixed axis, so as to change the direction and angle of air supply. However, the air deflector of traditional flat plate shape often has problems such as uneven air supply, limited air supply distance and poor air supply effect at certain angles when adjusting air supply direction.

[0004] Especially in some special use scenarios, such as air supply to the top or bottom of the room, the air deflector of traditional flat plate shape is difficult to meet the demand. In addition, the air deflector of flat plate shape is easily limited by its own shape, which may generate a lot of noise during rotation, and the adjustment of air supply angle is not flexible enough. SUMMARY

[0006] To achieve the above purpose, the utility model provides an air conditioner indoor unit, comprising:

[0007] A cabinet is configured to be installed on a wall, and a front lower part of the cabinet is provided with an air outlet;

[0008] A top side horizontal air deflector is rotationally connected with the cabinet, the rotation axis of the top side horizontal air deflector is φ1, and the maximum rotation radius of the top side horizontal air deflector is R1;

[0009] A bottom side horizontal air deflector is rotationally connected with the cabinet, the rotation axis of the bottom side horizontal air deflector is φ2, the maximum rotation radius of the bottom side horizontal air deflector is R2, the bottom side horizontal air deflector is provided in V shape, and φ2 is located at the bending position of the bottom side horizontal air deflector;

[0010] Wherein, the distance between φ1 and φ2 is L, and R2 < L ≤ R1 + R2.

[0011] Optionally, the rotation axis φ2 of the bottom side horizontal air deflector is located at the bottom side of the air outlet.

[0012] Optionally, the vertical distance between the rotation axis φ2 and the bottom surface of the housing is H, where H≤R2.

[0013] Optionally, the minimum gap between the bottom side transverse air guide plate and the bottom end of the air outlet is d, where 0 < d ≤ 10 mm.

[0014] Optionally, 3mm ≤ d ≤ 4mm.

[0015] Optionally, the bottom side transverse air guide plate includes a first air guide plate segment and a second air guide plate segment, wherein the included angle between the first air guide plate segment and the second air guide plate segment is β, and 90°≤β<180°.

[0016] Optionally, 130°≤β≤160°, so as to reduce the wind resistance of the bottom side transverse air guide plate while changing the airflow direction.

[0017] Optionally, 140°≤β≤150°.

[0018] Optionally, the rotation axis φ1 of the top side transverse air guide plate is located below the top of the air outlet and above the bottom of the air outlet.

[0019] Optionally, the top side transverse air guide plate is configured as an arc-shaped plate or a straight plate.

By ensuring R2 < L ≤ R1 + R2, the top and bottom horizontal air guide plates can rotate to an overlapping position during rotation, thereby jointly changing the direction of the airflow blown from the air outlet, and thus reducing or eliminating the leakage of airflow from the gap between the top and bottom horizontal air guide plates, resulting in better airflow guidance.

[0021] Furthermore, by positioning the rotation axis φ2 of the bottom horizontal air guide plate at the bottom of the air outlet, and ensuring that the vertical distance H between the bottom horizontal air guide plate and the bottom surface of the casing is less than or equal to R2, the bottom horizontal air guide plate can both guide airflow and reduce the area of ​​the bottom horizontal air guide plate obstructing the air outlet, thereby reducing wind resistance.

[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.

"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 Figures 1 to 4 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 top side horizontal air guide plate 200, and a bottom side horizontal air guide plate 300.

[0046] like Figure 1 and Figure 4 As shown, the housing 110 is configured to be mounted on a wall, meaning that the indoor air conditioner unit 001 of this utility model can be a wall-mounted indoor air conditioner unit 001. The housing 110 is provided with an air inlet 111 and an air outlet 112. The air inlet 111 can be located on the top side of the housing 110, and the air outlet 112 is located on 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 1 and Figure 4 In 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 112 to heat or cool the air flowing from the air inlet 111 to the air outlet 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 112.

[0052] like Figures 1 to 4 As shown, the top side transverse air guide plate 200 is rotatably connected to the housing 110, the rotation axis of the top side transverse air guide plate 200 is φ1, and the maximum rotation radius of the top side transverse air guide plate 200 is R1.

[0053] Furthermore, although not shown in the figure, in some embodiments of the present invention, the indoor unit 001 of the air conditioner also includes a motor mounted on the housing 110 and used to drive the top side transverse air guide plate 200 to rotate.

[0054] like Figures 1 to 4 As shown, the bottom horizontal air guide plate 300 is rotatably connected to the housing 110. The rotation axis of the bottom horizontal air guide plate 300 is φ2, the maximum rotation radius of the bottom horizontal air guide plate 300 is R2, the bottom horizontal air guide plate 300 is set to a V shape, and φ2 is located at the bend of the bottom horizontal air guide plate 300.

[0055] Furthermore, although not shown in the figure, in some embodiments of the present invention, the indoor unit 001 of the air conditioner also includes a motor mounted on the housing 110 and used to drive the bottom horizontal air guide plate 300 to rotate.

[0056] like Figure 4 As shown, the distance between φ1 and φ2 is L, and R2<L≤R1+R2.

[0057] Those skilled in the art will understand that by setting the bottom horizontal air guide plate 300 in a V-shape and placing the rotation axis φ2 of the bottom horizontal air guide plate 300 at the bend of the bottom horizontal air guide plate 300, a greater air delivery angle can be provided to the indoor unit 001 of the air conditioner compared to the flat air guide plate in the prior art. Furthermore, when the airflow passes over the V-shaped bottom horizontal air guide plate 300, the bottom horizontal air guide plate 300 can also diffuse or converge the airflow, thereby making the airflow more dispersed or farther. By ensuring that R2 < L ≤ R1 + R2, the top horizontal air guide plate 200 and the bottom horizontal air guide plate 300 can rotate to an overlapping position during rotation, thereby jointly changing the direction of the airflow blown from the air outlet 112, and thus reducing or eliminating the leakage of airflow from the gap between the top horizontal air guide plate 200 and the bottom horizontal air guide plate 300, resulting in better airflow guidance.

[0058] from Figure 1 , Figure 2 and Figure 4As can be seen from the above, in some embodiments of this utility model, the top side transverse air guide plate 200 is an arc-shaped plate.

[0059] Of course, in other embodiments of this utility model, those skilled in the art can also set the top side transverse air guide plate 200 as any feasible structure such as a straight plate, a corrugated plate, or a V-shaped plate, as needed.

[0060] from Figure 1 and Figure 4 As can be seen from this, in some embodiments of this utility model, the rotation axis φ2 of the bottom horizontal air guide plate 300 is located on the bottom side of the air outlet 112.

[0061] Furthermore, the vertical distance between the rotation axis φ2 and the bottom surface of the housing 110 is H, where H≤R2, so that the bottom side transverse air guide plate 300 can both guide the airflow and reduce the area of ​​the bottom side transverse air guide plate 300 blocking the air outlet 112.

[0062] like Figure 1 As shown, in some embodiments of this utility model, the minimum gap between the bottom horizontal air guide plate 300 and the bottom end of the air outlet 112 is d, 0 < d ≤ 10 mm, so as to ensure that the bottom horizontal air guide plate 300 does not interfere with the housing 110 during rotation, while avoiding excessive gap between the bottom horizontal air guide plate 300 and the housing 110, resulting in a loss of a large amount of air volume.

[0063] Furthermore, 3mm≤d≤4mm.

[0064] For example, d can be any feasible value such as 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 7.5mm, 10mm, etc.

[0065] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the bottom transverse air guide plate 300 includes a first guide plate segment 310 and a second guide plate segment 320. Furthermore, the rotation axis φ2 of the bottom transverse air guide plate 300 is located at the junction of the first guide plate segment 310 and the second guide plate segment 320. That is, the rotation axis φ2 of the bottom transverse air guide plate 300 is located at the bend of the bottom transverse air guide plate 300.

[0066] For example, the bottom transverse air guide plate 300 has two rotating shafts at both ends along the rotation axis φ2. The housing 110 has insertion holes adapted to these rotating shafts. The rotating shafts are inserted into these insertion holes, thereby mounting the bottom transverse air guide plate 300 onto the housing 110. The connection method between the top transverse air guide plate 200 and the housing 110 can be the same as that of the bottom transverse air guide plate 300.

[0067] like Figure 3 As shown, the included angle between the first guide plate section 310 and the second guide plate section 320 is β, 90°≤β<180°, to ensure that the bottom side transverse air guide plate 300 has a V-shaped structure and to avoid the first guide plate section 310 and the second guide plate section 320 increasing the airflow resistance due to the small included angle.

[0068] Furthermore, 130°≤β≤160°, so that the bottom side transverse air guide plate 300 can change the airflow direction while reducing the wind resistance of the bottom side transverse air guide plate 300.

[0069] Preferably, 140°≤β≤150°.

[0070] 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.

[0071] like Figures 5 to 10 As shown, in some embodiments of this utility model, the combination of the top side horizontal air guide plate 200 and the bottom side horizontal air guide plate 300 can enable the air conditioner indoor unit 001 to have six air supply modes.

[0072] like Figure 5 As shown, in the first air supply mode, the bottom horizontal air guide plate 300 and the top horizontal air guide plate 200 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.

[0073] like Figure 6 As shown, in the second air supply mode, the bottom horizontal air guide plate 300 and the top horizontal air guide plate 200 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.

[0074] like Figure 7 As shown, in the third air supply mode, the bottom horizontal air guide plate 300 and the top horizontal air guide plate 200 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 the 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.

[0075] like Figure 8As shown, in the fourth air supply mode, the bottom horizontal air guide plate 300 and the top horizontal air guide plate 200 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.

[0076] like Figure 9 As shown, in the fifth air supply mode, the bottom horizontal air guide plate 300 and the top horizontal air guide plate 200 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.

[0077] like Figure 10 As shown, in the sixth air supply mode, the bottom horizontal air guide plate 300 and the top horizontal air guide plate 200 can cause the airflow to blow downwards along their surfaces, and also allow 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.

[0078] In addition, in other embodiments of this utility model, those skilled in the art can, as needed, set at least one of the first diversion plate segment 310 and the second diversion plate segment 320 as an arc-shaped plate, and make the concave side of the arc-shaped plate located inside the bottom transverse air guide plate 300, so as to increase the guiding angle of the bottom transverse air guide plate 300 for the airflow.

[0079] Based on the foregoing description, those skilled in the art will understand that the air conditioning indoor unit 001 of this utility model, which has a top side horizontal air guide plate 200 and a bottom side horizontal air guide plate 300, can achieve more air supply modes and improve the user experience.

[0080] 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.

[0081] 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.
