[0031] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] In the description of the present invention, the meaning of "a plurality" is two or more.

[0034] The air conditioner indoor unit 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] As Figures 1 - 8 shown, the air conditioner indoor unit 1 according to an embodiment of the present invention includes a housing 100, a longitudinal air deflector 200, and an angle adjusting member 300.

[0036] The housing 100 is provided with an air outlet 110. The air outlet 110 can be arranged towards the front lower side. The longitudinal air deflector 200 is an integral part. The longitudinal air deflector 200 is installed on the housing 100 and is located at the air outlet 110. The angle adjusting member 300 is provided on the housing 100 and cooperates with the longitudinal air deflector 200. For example, both ends of the angle adjusting member 300 are connected to the opposite side walls of the air outlet 110. The longitudinal air deflector 200 changes the air outlet angle through its own elastic deformation under the action of the angle adjusting member 300.

[0037] Among them, the fact that the longitudinal air deflector 200 is a single-piece refers to that the longitudinal air deflector 200 is directly manufactured as a single integral part during the manufacturing process, rather than assembled as a single integral component during the assembly process. Moreover, the longitudinal air deflector 200 can be made of materials with relatively good toughness, for example, materials such as PP (Polypropylene) or PET (Polyethylene terephthalate).

[0038] For the air conditioner indoor unit 1 according to an embodiment of the present invention, by making the longitudinal air deflector 200 a single-piece and the longitudinal air deflector 200 being located at the air outlet 110, the number of parts of the air conditioner indoor unit 1 is reduced, it is easy to disassemble and assemble, the assembly efficiency of the air conditioner indoor unit 1 is improved, the production efficiency is enhanced, and it is also convenient for cleaning and maintenance of the longitudinal air deflector 200 during use.

[0039] Moreover, the angle adjusting member 300 cooperates with the longitudinal air deflector 200. Under the action of the angle adjusting member 300, the longitudinal air deflector 200 changes the air outlet angle through its own elastic deformation, ensuring the function of the longitudinal air deflector 200 for air outlet guiding, thereby realizing air swing. That is, while the longitudinal air deflector 200 adopts an integral structure, its original functions can be ensured.

[0040] In this way, the air conditioner indoor unit 1 according to an embodiment of the present invention has the advantages of fewer parts, convenient disassembly and assembly, high assembly efficiency, and easy maintenance.

[0041] According to some specific embodiments of the present invention, as Figure 4 shown, the longitudinal air deflector 200 includes a first connecting rod 210, a second connecting rod 220, and a plurality of air deflector blades 230.

[0042] The first connecting rod 210 and the second connecting rod 220 are arranged at intervals. For example, both the first connecting rod 210 and the second connecting rod 220 extend in the left-right direction. The first connecting rod 210 is located in front of and above the second connecting rod 220. The second connecting rod 220 is installed on the housing 100. One end of each air deflector blade 230 is connected to the first connecting rod 210 and the other end is connected to the second connecting rod 220. The plurality of air deflector blades 230 are arranged at intervals along the length directions of the first connecting rod 210 and the second connecting rod 220. Among them, the angle adjusting member 300 cooperates with the first connecting rod 210. Under the action of the angle adjusting member 300, the first connecting rod 210 drives the plurality of air deflector blades 230 to swing. In other words, when the angle adjusting member 300 acts on the first connecting rod 210, the first connecting rod 210 drives the plurality of air deflector blades 230 to undergo corresponding deformation from top to bottom, thereby changing the air outlet angle.

[0043] For example, each air guiding vane 230 is provided with a plurality of through holes penetrating along its thickness direction to facilitate the detection performance during the production of the air conditioner indoor unit 1. The longitudinal air guiding plate 200 can be injection molded, and each air guiding vane 230 can be provided with a bend along its thickness direction to facilitate demolding during manufacturing. The length of the first connecting rod 210 is not greater than 800 mm to facilitate the adjustment of the angles of the plurality of air guiding vanes 230.

[0044] In this way, the arrangement of the plurality of air guiding vanes 230 facilitates the adjustment of the air outlet direction. The arrangements of the first connecting rod 210 and the second connecting rod 220 not only fix the relative positions between the longitudinal air guiding plate 200 and the housing 100, but also facilitate the cooperation with the angle adjusting member 300 to realize the rotation of the plurality of air guiding vanes 230.

[0045] According to some specific embodiments of the present invention, such as Figure 4 As shown, the first connecting rod 210 is provided with a plurality of adjusting teeth 240, and the plurality of adjusting teeth 240 include a central tooth 241, a plurality of first side teeth 242, and a plurality of second side teeth 243.

[0046] The central tooth 241 extends along the width direction of the first connecting rod 210. The plurality of first side teeth 242 are located on one side (for example, the left side) of the central tooth 241 in the length direction of the first connecting rod 210. Each first side tooth 242 is inclined with respect to the width direction of the first connecting rod 210, and the angles between the plurality of first side teeth 242 and the width direction of the first connecting rod 210 are different. The plurality of second side teeth 243 are located on the other side (for example, the right side) of the central tooth 241 in the length direction of the first connecting rod 210. Each second side tooth 243 is inclined with respect to the width direction of the first connecting rod 210, and the angles between the plurality of second side teeth 243 and the width direction of the first connecting rod 210 are different.

[0047] For example, the angle between each first side tooth 242 and the central tooth 241 is 0° to 40°, and the angle between each second side tooth 243 and the central tooth 241 is 0° to 40°. The outer contour of the cross-section of each adjusting tooth 240 can be arc-shaped to facilitate the movement of the angle adjusting member 300 between the plurality of adjusting teeth 240.

[0048] Among them, the angle adjusting member 300 acts on the first connecting rod 210 by cooperating with different adjusting teeth 240, thereby driving the plurality of air guiding vanes 230 to undergo different degrees of deformation to adjust the air outlet angle.

[0049] Specifically, as Figure 4As shown, the included angles between the multiple first side teeth 242 and the width direction of the first connecting rod 210 gradually increase in the direction away from the central tooth 241, and the included angles between the multiple second side teeth 243 and the width direction of the first connecting rod 210 gradually increase in the direction away from the central tooth 241. The positions of the multiple adjusting teeth 240 provided on the first connecting rod 210 can protrude towards the second connecting rod 220, which ensures that when the longitudinal air deflector 200 is installed, the angle adjusting member 300 contacts the multiple adjusting teeth 240, and also increases the tightness of the contact between the angle adjusting member 300 and the multiple adjusting teeth 240.

[0050] Among them, the multiple adjusting teeth 240 are provided on the surface of the first connecting rod 210 facing the multiple air guiding vanes 230, that is, the multiple adjusting teeth 240 are provided on one side of the first connecting rod 210 facing the second connecting rod 220, and the multiple first side teeth 242 and the multiple second side teeth 243 are symmetrically arranged with respect to the central tooth 241. In this way, not only the left and right swinging angles of the longitudinal air deflector 200 are symmetric, but also it is convenient for processing.

[0051] In this way, when the angle adjusting member 300 cooperates with the first side teeth 242, it will cause the first connecting rod 210 to drive the multiple air guiding vanes 230 to rotate to the right, so as to blow air to the right. The farther the first side teeth 242 cooperating with the angle adjusting member 300 are from the central tooth 241, the larger the inclination angle of the first side teeth 242, and correspondingly, the larger the rotation angle of the air guiding vanes 230 to the right; when the angle adjusting member 300 cooperates with the second side teeth 243, it will cause the first connecting rod 210 to drive the multiple air guiding vanes 230 to rotate to the left, so as to blow air to the left. The farther the second side teeth 243 cooperating with the angle adjusting member 300 are from the central tooth 241, the larger the inclination angle of the second side teeth 243, and correspondingly, the larger the rotation angle of the air guiding vanes 230 to the left.

[0052] According to some specific embodiments of the present invention, as Figure 4 shown, the thickness of each air guiding vane 230 at the end connected to the first connecting rod 210 is greater than the thickness of the end of the air guiding vane 230 connected to the second connecting rod 220, and / or the width of each air guiding vane 230 at the end connected to the first connecting rod 210 is greater than the width of the end of the air guiding vane 230 connected to the second connecting rod 220.

[0053] Since the force that causes the air guiding vane 230 to rotate is transmitted by the first connecting rod 210, the acting force received by the air guiding vane 230 gradually decreases from top to bottom. By setting the thickness and / or width at both ends of the air guiding vane 230, the end of the air guiding vane 230 connected to the second connecting rod 220 is relatively easy to deform, and the end of the air guiding vane 230 connected to the first connecting rod 210 is relatively difficult to deform. In this way, combined with the force distribution of the air guiding vane 230, that is, the relatively easy-to-deform part receives a small acting force, and the relatively difficult-to-deform part receives a large acting force, so that the air guiding vane 230 rotates as a whole, avoiding the air guiding vane 230 from being twisted.

[0054] According to some specific embodiments of the present invention, as Figure 4 shown, the second connecting rod 220 is provided with a notch 250, and the angle adjusting member 300 is arranged at the notch 250 and supports the first connecting rod 210.

[0055] Wherein, one end of the angle adjusting member 300 close to the first connecting rod 210 is provided with an opening 310, the direction of the opening 310 faces the outside of the air inlet 110, the first connecting rod 210 is embedded in the opening 310 and can slide in the left-right direction, and the bottom wall of the opening 310 is matched with the adjusting tooth 240, which increases the stability of the contact between the angle adjusting member 300 and the adjusting tooth 240, and prevents the relative movement between the angle adjusting member 300 and the adjusting tooth 240 not according to the user's requirements.

[0056] In this way, the angle adjusting member 300 is arranged at the notch 250, providing an accommodation space for the angle adjusting member 300, and the angle adjusting member 300 is not arranged at both ends of the longitudinal air guiding plate 200 in the length direction, that is, the adjusting tooth 240 is not arranged at both ends of the first connecting rod 210 in the length direction. Therefore, the torsional force of the first connecting rod 210 on the air guiding vanes 230 on both sides is more easily transmitted. And, the installation space is saved and the space utilization rate is improved.

[0057] Furthermore, as Figure 4 、 Figure 6 and Figure 8 shown, a plurality of front card slots 221 are arranged at intervals along the length direction of the second connecting rod 220 on the side (front side) of the second connecting rod 220 facing the outside of the air outlet 110, and a plurality of rear buckles 222 are arranged at intervals along the length direction of the second connecting rod 220 on the side (rear side) of the second connecting rod 220 facing the inside of the air outlet 110. The housing 100 is provided with a plurality of front buckles 120 and a plurality of rear card slots 130. The plurality of front buckles 120 are respectively engaged with the plurality of front card slots 221, and the plurality of rear buckles 222 are respectively engaged with the plurality of rear card slots 130.

[0058] For example, the housing 100 is provided with an installation groove 140, the second connecting rod 220 is installed in the installation groove 140, the surface of the second connecting rod 220 facing the first connecting rod 210 is flush with the surface of the housing 100, and the side surface of the second connecting rod 220 is in contact with the side surface of the installation groove 140. Moreover, a plurality of front buckles 120 and a plurality of rear clamping grooves 130 are respectively arranged on the front and rear side walls of the installation groove 140.

[0059] In this way, through the setting of the installation groove 140, the contact area between the housing 100 and the second connecting rod 220 is increased, the installation stability of the longitudinal air deflector 200 is increased, and the neatness at the air outlet 110 is also increased. Moreover, a plurality of front buckles 12 cooperate with a plurality of front clamping grooves 221, and a plurality of rear buckles 222 cooperate with a plurality of rear clamping grooves 130, further preventing relative displacement between the housing 100 and the second connecting rod 220. In addition, when installing the longitudinal air deflector 200, a plurality of rear buckles 222 at the rear side of the second connecting rod 220 can be first snapped into a plurality of rear clamping grooves 130, and then the front side of the second connecting rod 220 is pressed to make a plurality of front buckles 12 cooperate with a plurality of front clamping grooves 221. Thus, combined with the structure of the air conditioner outdoor unit 100, the operation during the disassembly and assembly of the longitudinal air deflector 200 can be facilitated.

[0060] According to some specific embodiments of the present invention, as Figure 4 , Figure 6 and Figure 8 shown, the air conditioner indoor unit 1 further includes a deflector 400, and the deflector 400 is installed on the housing and is fixed in relative position with the housing 100. The deflector 400 is provided with a hook 410, and the first connecting rod 210 is provided with a hanging groove 260 extending along its length direction. The hook 410 is hooked on the hanging groove 260 and can move along the length direction of the hanging groove 260.

[0061] Among them, the length direction of the hanging groove 260 is the same as the width direction of the hook 410, and the length of the hanging groove 260 is greater than the width of the hook 410. The hooks 410 are a plurality arranged at intervals along the length direction of the deflector 400, and the hanging grooves 260 are a plurality arranged at intervals along the length direction of the first connecting rod 210. A plurality of hooks 410 and a plurality of hanging grooves 260 are in one-to-one correspondence and cooperation. Each hook 410 is provided with a bend facing the outside of the air outlet 110, increasing the connection stability between the deflector 400 and the first connecting rod 210.

[0062] For example, a clamping notch 420 is provided on the surface of the deflector 400 facing the angle adjuster 300, and the angle adjuster 300 is embedded in the clamping notch 420, reducing the distance between the deflector 400 and the first connecting rod 210, increasing the connection stability between the deflector 400 and the angle adjuster 300, saving the installation space of the air conditioner indoor unit 1, and improving the space utilization rate.

[0063] In this way, through the cooperation of the hook 410 and the hanging groove 260, not only is the first connecting rod 210 prevented from detaching from the deflector 400, that is, the first connecting rod 210 is prevented from detaching from the housing 100, but also the first connecting rod 210 can move along the length direction of the first connecting rod 210, enabling the angle adjusting member 300 to cooperate with different adjusting teeth 240, that is, changing the air guiding directions of the plurality of air guiding vanes 230.

[0064] According to some specific embodiments of the present invention, as Figure 4 shown, the first connecting rod 210 is provided with a manual driving portion 270 for controlling the movement of the first connecting rod 210 relative to the angle adjusting member 300, and / or the air conditioner indoor unit 1 further includes an angle adjusting motor (not shown in the figure), and the angle adjusting motor is connected to the first connecting rod 210 to drive the first connecting rod 210 to move relative to the angle adjusting member 300.

[0065] In some embodiments of the present invention, as Figure 4 shown, there may be a plurality of manual driving portions 270, and the plurality of manual driving portions 270 are arranged at intervals along the length direction of the first connecting rod 210 on both sides of the plurality of adjusting teeth 240. The manual driving portion 270 protrudes from the surface of the first connecting rod 210 facing the second connecting rod 220, and the user can hold the manual driving portion 270 to drive the first connecting rod 210 to move along the length direction of the first connecting rod 210. In this way, energy is saved and the usage cost is reduced.

[0066] In some other embodiments of the present invention, the air conditioner indoor unit 1 is provided with an angle adjusting motor, and the angle adjusting motor is connected to one end of the first connecting rod 210 and the position where the plurality of adjusting teeth 240 are provided, and the angle adjusting motor drives the first connecting rod 210 to move along the length direction of the first connecting rod 210. In this way, the automation of the air conditioner indoor unit 1 can be improved.

[0067] In this way, it is convenient to realize the cooperation between the angle adjusting member 300 and different adjusting teeth 240, and it is convenient for the air guiding directions of the plurality of air guiding vanes 230 to meet the user's needs.

[0068] Those skilled in the art can understand that the manual driving portion 270 and the angle adjusting motor can be provided simultaneously, increasing the diversity of driving the first connecting rod 210 to move.

[0069] Other components of the air conditioner indoor unit 100 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.

[0070] For example, an air conditioner having the above-described outdoor unit 100 of the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0071] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state 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 heat is released to the surrounding environment through the condensation process.

[0072] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state that has been condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant that has expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by performing a heat exchange with the material to be cooled by using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0073] The outdoor unit 100 of the air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit of the air conditioner.

[0074] The indoor heat exchanger and the outdoor heat exchanger serve as condensers or evaporators. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in the cooling mode.
