DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0024] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0025] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0026] An air conditioner outdoor unit refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. An air conditioner indoor unit includes the indoor heat exchanger, and an expansion valve can be provided in either the outdoor or indoor unit.

[0027] The indoor heat exchanger and the outdoor heat exchanger are used as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

[0030] In order to ensure that the deflector 31 and the movable plate 41 do not dislocate during rotation, the rotation axis of the deflector 31 and the rotation axis of the movable plate 41 are coaxially arranged. In addition, the rotation axis of the deflector 31 and the rotation axis of the movable plate 41 are coaxially arranged, that is, the movable plate 41 and the deflector 31 rotate around the same rotation axis. As long as the movable plate driving device and the deflector driving device rotate by the same angle, it can be ensured that the upper edge of the deflector 31 and the lower edge of the movable plate 41 are completely fitted, and the control process of the movable plate driving device and the deflector driving device is more simple and convenient.

The bifurcated structure can make the connection between the transmission assembly and the movable plate 41 more stable, ensure that the movable plate 41 is balanced in the movement process and is not easy to jam, and also avoid the upper edge or / and the lower edge of the movable plate 41 from tilting, which causes the movable plate 41 and the front panel 100 to be unable to fit.

[0038] The above-mentioned movable plate 41 driving device in the embodiments of the present application has two groups and is connected with the two ends of the length direction of the movable plate 41 respectively, so that when the movable plate 41 rotates between the stowed position and the open position, the force on the two ends of the length direction of the movable plate 41 is balanced, avoiding the problem that the movable plate 41 may be deformed in the rotating process due to the force on one end and no force on the other end.

[0039] In some embodiments of the present application, the above-mentioned air conditioner indoor unit further comprises a first guide structure, the first guide structure comprises a first arc-shaped sliding groove arranged on the left side plate of the shell 1 and a first arc-shaped protrusion arranged on the first circular arc rack 43, the first arc-shaped protrusion and the first arc-shaped sliding groove are in sliding fit, and the arc of the first arc-shaped protrusion, the first arc-shaped sliding groove and the first circular arc rack 43 are all equal, so as to guide the first circular arc rack 43 to rotate between the stowed position and the open position.

[0040] Similarly, the above-mentioned air conditioner indoor unit further comprises a second guide structure, the second guide structure comprises a second arc-shaped sliding groove arranged on the left side plate of the shell 1 and a second arc-shaped protrusion arranged on the second circular arc rack 45, the second arc-shaped protrusion and the second arc-shaped sliding groove are in sliding fit, and the arc of the second arc-shaped protrusion, the second arc-shaped sliding groove and the second circular arc rack 45 are all equal, so as to guide the second circular arc rack 45 to rotate between the stowed position and the open position.

[0041] Referring to Figure 2 , Figure 3 and Figure 4 , the above-mentioned air deflector driving device comprises a driving motor 33, the driving motor 33 is installed in the shell 1, and the axis direction of the output shaft of the driving motor 33 is consistent with the length direction of the air deflector 31; a rotating arm 32, one end of the rotating arm 32 is fixed on the output shaft of the driving motor 33, and the other end is fixed with the windward side of the air deflector 31; a recess 322 is formed on the rotating arm 32, which can avoid the bottom wall of the shell 1 when the air deflector 31 is gradually opened from the first position. In the specific use process, when the above-mentioned air conditioner indoor unit is in the cooling mode or the heating mode, the air deflector driving device drives the air deflector 31 to rotate to the third position at this time, wherein the distance between the air deflector 31 in the second position and the air outlet 120 is less than the distance between the air deflector 31 in the third position and the air outlet 120, that is, the air deflector 31 is farther away from the air outlet 120 when it is in the third position, at this time, since the above-mentioned recess 322 can avoid the bottom wall of the shell 1, it can ensure that the air deflector 31 completely opens the air outlet 120, that is, the air deflector 31 will not hinder the air outlet, and ensure that the air volume of the air outlet 120 is not affected.

[0042] Since the length of the first circular arc rack 43 and the second circular arc rack 45 is limited, i.e. the distance between the front panel 100 of the casing 1 and the rear side wall of the casing 1 is limited, the maximum rotation angle of the movable plate is 45°-120°.

[0043] In specific embodiments, when the air deflector driving device drives the air deflector 31 to rotate by a first angle α so that the air deflector is located at the second position, and then the movable plate driving device drives the movable plate 41 to rotate by a second angle β, where α=β, it can be ensured that the lower edge of the movable plate 41 and the upper edge of the air deflector 31 are fitted, and the cold air blown out of the air outlet 120 is entirely blown to the roof. At this time, the first angle α and the second angle β are both less than or equal to the maximum rotation angle of the movable plate.

[0044] Wherein, the first angle α and the second angle β are both greater than or equal to 10°, the second angle β is equal to the first angle α, and less than the maximum rotation angle of the movable plate. Only when the first angle α and the second angle β are in this range, the air deflector 31 and the movable plate 41 can be docked together to guide the air out. When the first angle α and the second angle β are both less than 10°, the air resistance of the air outlet 120 is too large, which makes the noise of the air conditioner indoor unit relatively low, and the air volume is too small to achieve good cooling effect.

[0045] Based on the above embodiments, the air conditioner indoor unit further comprises an inner air deflector 5, which is installed between the fan 2 and the air outlet 120 and is rotationally connected with the casing 1, for adjusting the air outlet direction of the air outlet 120, as shown in Figure 5 When the air conditioner indoor unit is in the heating mode or the cooling mode, i.e. the air deflector driving device drives the air deflector 31 to rotate to the third position, at this time the air volume is large, and then the rotation of the inner air deflector 5 can control the air direction, adjust different air directions, achieve good cooling or heating comfort, and improve user experience.

[0046] In order to realize the rotation of the inner air deflector 5, the air conditioner indoor unit further comprises an inner air deflector driving device, which can drive the inner air deflector 5 to rotate relative to the casing 1 to adjust the air outlet direction.

[0047] In some embodiments of the present application, the end of the rotating arm 32 close to the driving motor 33 is provided with a special-shaped hole 321, the special-shaped hole 321 is arranged in the same direction as the length direction of the air deflector 31 and penetrates through the rotating arm 32, the cross-sectional shape of the output shaft of the driving motor 33 is the same as the cross-sectional shape of the special-shaped hole 321, the output shaft of the driving motor 33 is inserted into the special-shaped hole 321. Compared with the welding connection mode, the above connection mode makes the connection between the driving motor 33 and the rotating arm 32 more convenient, and facilitates the disassembly between the driving motor 33 and the rotating arm 32.

[0048] Alternatively, the connection between the rotating arm 32 and the output shaft of the driving motor 33 can also be screw-fixed or clamped.

[0049] The special-shaped hole 321 can be a triangular hole, a square hole, a hexagonal hole or an oval hole, and the specific shape of the special-shaped hole 321 is not limited in the embodiments of the present application, as long as the output shaft of the driving motor 33 and the special-shaped hole 321 are matched and relative rotation therebetween does not occur.

[0050] Referring to Figure 1 , Figure 7 and Figure 8 , the air conditioner indoor unit further comprises a display panel 6, which is arranged on the front panel 100 of the shell 1 and can be used to display the working mode, air speed, indoor temperature and other parameters of the air conditioner indoor unit.

[0051] The display panel 6 is fixedly arranged on the front panel 100 of the shell 1 and integrally formed with the front panel 100, or the display panel 6 can be connected to the front panel 100 in a detachable manner.

[0052] Referring to Figure 8 , the front panel 100 is provided with a corresponding avoiding groove 200, so that the first and second circular arc racks 43 and 45 extend out of the front panel 100 from the avoiding groove 200 and are connected to the movable plate 41, and the first circular arc rack 43 can be driven by the first gear 42 to rotate away from the rear side wall of the shell, and the second circular arc rack 45 can be driven by the second gear 44 to rotate away from the rear side wall of the shell.

[0053] For the embodiment with two sets of movable plate driving devices, the avoiding groove 200 corresponds to two.

[0054] In some embodiments, the rotating arm 32 has two and is respectively connected to the two ends of the length direction of the air deflector 31, and the driving motor 33 has two and is respectively used to drive the two rotating arms 32, so that the air deflector 31 is more stable and reliable during rotation and is not easy to be stuck, as shown in Figure 6 and Figure 8 .

[0055] In order to further ensure that the air deflector 31 is more stable and reliable during rotation and is not easy to be stuck, the rotating arm 32 can have multiple, and the corresponding driving motor 33 has multiple, the multiple rotating arms 32 are arranged at intervals, and the spacing between every two adjacent rotating arms 32 is equal.

[0056] In the above embodiment, in order to make the movement of the air deflector 31 more stable, guide grooves can be arranged on the two opposite side walls of the shell 1, and the air deflector 31 is in sliding fit with the guide grooves to guide the rotation of the air deflector 31.

[0057] In some embodiments of the present application, the first circular arc rack 43 and the second circular arc rack 45 are connected to the movable plate 41 through clamping connection. Compared with the connection mode of screw fastening connection, the connection mode of clamping connection is more simple and convenient.

[0059] It should be pointed out that the first clamping hook, the second clamping hook and the movable plate 41 are integrally formed by a one-piece forming process, which avoids installation errors caused by secondary installation, and is beneficial to shorten the installation time of the air conditioner indoor unit and improve the installation efficiency of the air conditioner indoor unit.

[0060] In order to reduce the air outlet noise, the air deflector 31 and the movable plate 41 are both arranged as circular arc plates, and the concave surface of the circular arc plate faces the inside of the shell 1. Thus, the direction of the cold air blown by the fan 2 in the shell 1 changes more smoothly when it contacts the concave surface, and the noise generated when the air outlet collides with the air deflector 31 and the movable plate 41 is relatively small, thereby reducing the operation noise of the indoor unit.

[0061] In addition, the curvature of the movable plate 41 is the same as the curvature of the front panel 100 of the shell 1, which ensures that the movable plate 41 can be completely attached to the front panel 100 when it is in the stowed position, so that the appearance of the air conditioner indoor unit is more beautiful.

[0062] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0063] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
