Referring to fig. 1 to 10, a housing 110 includes a chassis 111 and a face frame 112, the chassis 111 and the face frame 112 cooperate to form an air duct 120, the air duct 120 has an air outlet 124, and hot air or cold air blown by an air conditioner indoor unit 100 can be blown into a room through the air outlet 124. The air guide assembly 130 is arranged at the air outlet 124, and the air outlet 124 can be rotationally sealed or the opening degree of the air outlet 124 is changed through the first air guide plate 140 and the second air guide plate 150, so that the air flow blown out from the air outlet 124 is guided, different air outlet effects can be realized under the refrigerating mode or the heating mode of the air conditioner through the arrangement of the first air guide plate 140 and the second air guide plate 150, the air flow under different working conditions is effectively rectified, and the air outlet volume and the temperature regulating effect of the air conditioner are improved.

Referring to fig. 2, the first air guide plate 140 and the second air guide plate 150 together close the air outlet 124, and compared with a case that one air guide plate is independently used to close the air outlet 124, the appearance of the air conditioner can be improved, and the size of a gap in appearance can be reduced. The single wind deflector has large appearance clearance with the air outlet 124 in the closed state and the starting state due to errors in the limited manufacturing process and the assembly process, so that the problem of appearance can be solved through the arrangement of the first wind deflector 140 and the second wind deflector 150, different air outlet effects can be realized in the refrigerating mode or the heating mode of the air conditioner, and the air outlet quantity and the temperature regulating effect of the air conditioner are improved.

It should be noted that, the rotation means that the first air deflector 140 and the second air deflector 150 cooperate to seal the air outlet 124 in a manner of rotating around the center of a circle; or the opening of the air outlet 124 is changed so as to control the air flow blown out from the air outlet 124.

The opening degree of the air outlet 124 indicates that the air outlet 124 is completely shielded by the first air deflector 140 and the second air deflector 150 until the air outlet 124 is exposed, and the larger the area of the exposed air outlet 124 is, the larger the opening degree of the air outlet 124 is, and vice versa.

Specifically, the length of the first air deflector 140 extending along the circumferential direction thereof is greater than the length of the second air deflector 150 extending along the circumferential direction thereof, and the air guiding assembly 130 further includes a louver air sweeping device mounted on the first air deflector 140.

Further, the outer surfaces of the first air deflector 140 and the second air deflector 150 at the side far away from the louver wind sweeping device are arc-shaped, and the centers of circles of the outer surfaces are coincident with the rotation centers of the first air deflector 140 and the second air deflector 150. The outer arc center of the existing air deflector is not coincident with the rotation center thereof, which results in larger appearance gaps in a closed state and a starting state, and in addition, in the process of blowing out air from the air outlet 124, the problem of air leakage is easy to occur, turbulence is generated at the air deflector to influence the air outlet effect, and the air outlet 124 is generally rectangular in cross section, and the movement tracks of the first air deflector 140 and the second air deflector 150 are circular, so that the circular arrangement is in the rectangle, the first air deflector 140 and the second air deflector 150 can be closer to the cavity wall of the air outlet 124, thereby reducing the problem of air leakage, improving the problem of large appearance gap and influencing the beauty.

Referring to fig. 2 to 6, in order to further solve the problems of air leakage and appearance, one side of the air duct 120 includes a volute tongue section 121 and an air outlet section 122 connected to the volute tongue section 121, the air guide assembly 130 is correspondingly disposed at the air outlet section 122, a portion of the air outlet section 122 near the air outlet 124 is adapted to be bent to form an arc avoidance portion 123, and the first air guide plate 140 and the second air guide plate 150 are rotatably disposed at the arc avoidance portion 123.

The volute tongue section 121 and the air outlet section 122 are the portions of the face frame 112 forming the air duct 120, and the outer surfaces of the first air deflector 140 and the second air deflector 150 are arc-shaped, so that when the first air deflector 140 and the second air deflector 150 are located at the arc-shaped avoiding portion 123, the first air deflector and the second air deflector are equivalent to the portions which can be regarded as being connected with the volute tongue section 121 to form the air duct 120, and thus the problem of air leakage in the heating process or the cooling process can be solved, and the problem of large appearance gaps can be overcome.

Specifically, the louver wind sweeping device includes a louver wind sweeping structure 160, a plurality of wind sweeping blades of the louver wind sweeping structure 160 are arranged at intervals along a rotation axis of the first air deflector 140 and can swing along the rotation axis of the first air deflector 140, and the louver wind sweeping structure 160 is in clamping fit with the first air deflector 140. The wind sweeping blade comprises a blade vertical to the wind direction and a blade horizontal to the wind direction, and the wind sweeping blade and the blade horizontal to the wind direction are connected in series through a pull rod, and when the wind sweeping blade works, the motor drives the wind sweeping blade to swing in the vertical direction or swing in the horizontal direction.

Referring to fig. 2, the wind sweeping blade is installed on the first wind deflector 140, in order to control the weight of the first wind deflector 140 and facilitate the installation of the first wind deflector 140, in an embodiment, the first wind deflector 140 is hollow, a clamping groove 141 is provided in the middle of the first wind deflector 140, and the shutter wind sweeping structure 160 is provided with a buckle 161 corresponding to the clamping groove 141, and the buckle 161 is clamped with the clamping groove 141. Compared with the structure 160 with the louver, the first air deflector 140 is hollow, the arrangement of the clamping grooves 141 is more convenient, and the first air deflector 140 with the hollow has a deformed space, so that the clamping grooves 141 are more convenient to clamp on the first air deflector 140.

The hollow air guide plates improve the structural strength of the first air guide plates 140 and reduce the weight of the first air guide plates 140; the first wind deflector 140 and the louver wind sweeping structure 160 adopt a clamping mode, so that the number of screws is reduced, stability is ensured, and meanwhile, the efficiency of the installation process is improved.

In another embodiment, the first air deflection 140 is an arcuately curved plate.

Referring to fig. 2, further, in order to improve structural strength and also to facilitate installation, the first air deflector 140 is formed with a reinforcing rib 142 extending inward from the edge of the slot 141, and the reinforcing rib 142 may abut against the hollow cavity wall of the first air deflector 140 under the action of an external force. Be equipped with a plurality of draw-in grooves 141 on the length direction of first aviation baffle 140, for example all be provided with in tip and/or intermediate position, during the installation, because first aviation baffle 140 is the cavity setting, with buckle 161 corresponding draw-in groove 141 press down the in-process, the deformation can be found to the one side that draw-in groove 141 of first aviation baffle 140 is located, inwards sunken, in this process, because the relation of first aviation baffle 140 length, probably deformation in intermediate position leads to the installation application point weaker more easily, consequently set up the strengthening rib 142 at draw-in groove 141, butt hollow chamber wall provides reverse holding power when the deformation, thereby reach the effect of being convenient for the installation, also improve joint position structural strength, in this process of follow-up dismantlement also can not influence the stability of follow-up installation because of the notch deformation of draw-in groove 141.

In order to better improve the air output and temperature regulation effect of the air conditioner, one side of the first air deflector 140 facing the louver air sweeping device is a concave cambered surface, and one side of the second air deflector 150 facing the louver air sweeping device is a convex cambered surface or plane. The concave cambered surface of the first air deflector 140 and the convex cambered surface or plane of the second air deflector 150 can play a role in guiding air flow, so that the positions of the first air deflector 140 and the second air deflector 150 are matched, different air outlet effects can be realized in a refrigerating mode or a heating mode of the air conditioner, and the air outlet quantity and the temperature regulating effect of the air conditioner are improved.

The first air deflector 140 is longer than the second air deflector 150, the concave cambered surface of the first air deflector 140 plays a role in guiding the air flow, the convex cambered surface or plane of the second air deflector 150 also plays a role in guiding the air flow, the air flow passing through the first air deflector 140 is the same as the concave cambered surface, and the convex cambered surface or plane of the second air deflector 150 can play an adsorption role on the air flow, so that when the first air deflector 140 is positioned at the arc avoiding part 123, the air flow can deflect downwards.

Conversely, when the first air deflector 140 is below and the second air deflector 150 is above, that is, the arc-shaped avoiding portion 123, the first air deflector 140 is longer than the second air deflector 150, so that the air flow can be conveyed farther, the air guiding range is improved, and the air supply comfort is improved.

The sizes of the first opening 131 and the second opening 132 are similar to each other, and the sizes of the openings at both ends of the channel between the first air deflector 140 and the second air deflector 150 are not much different in the flowing direction of the air flow, for example, the difference between the area of the first opening 131 and the area of the second opening 132 is not more than 0.1mm2.

In the first mode, hot air passes through the first air guide plate 140 and the second air guide plate 150 from the air duct 120, and because the length of the first air guide plate 140 is larger than that of the second air guide plate 150, a downward gap is formed between the first air guide plate 140 and the second air guide plate 150, the outer surface of the first air guide plate 140 is suitable for being arranged at the arc avoidance part 123, the problem of air leakage cannot occur, the inner surface of the first air guide plate 140 is a concave cambered surface, the outer surface of the second air guide plate 150 is a convex curved surface or a plane, the air flow generates an adsorption effect through the second air guide plate 150, the air flow is guided to the gap through the first air guide plate 140 to be reserved, the hot air can be better sunk along the wall surface, the air quantity for heating can be improved, the air supply angle is larger, and the air supply effect is better.

Because the length of the first air deflector 140 is greater than that of the second air deflector 150, a downward gap is formed between the first air deflector 140 and the second air deflector 150, the outer surface of the first air deflector 140 is suitable for being arranged at the arc avoidance part 123, the problem of air leakage is avoided, the inner surface of the first air deflector 140 is a concave cambered surface, the outer surface of the second air deflector 150 is a convex cambered surface or plane, the air flow passes through the second air deflector 150 to generate adsorption, the first opening 131 and the second opening 132 form a horn mouth with large inner side and small outer side, and hot air is intensively blown out from the second opening 132 to form fixed-point concentrated heat supply, so that heating can be performed rapidly. For example, the indoor unit 100 of the air conditioner is provided with an infrared sensor to monitor the moving position of a person, the first air deflector 140 rotates to a specific position or a specific angle towards the arc avoidance portion 123, the second air deflector 150 reversely rotates to the specific position or the specific angle, and meanwhile, the wind sweeping blades of the louver wind sweeping device swing according to the moving position of the person, so that fixed-point rapid heating is realized, and the user experience is improved.

Because the length of first aviation baffle 140 is greater than the length of second aviation baffle 150, the length of arc dodges the portion 123 and is slightly greater than or equal to the length of first aviation baffle 140, the surface of second aviation baffle 150 is suitable for placing arc dodges the portion 123 department, can not produce the problem of gas leakage, first aviation baffle 140 is equivalent to the arc and dodges the portion 123 cooperation and form air-out section 122 like this, and the internal surface of first aviation baffle 140 is the cambered surface of indent, the surface of second aviation baffle 150 is the curved surface or the plane of evagination, the air current produces the adsorption through second aviation baffle 150 department like this, the size of first opening 131 and second opening 132 is similar, like this under the refrigeration mode, the cooperation of first aviation baffle 140 and second aviation baffle 150 makes the air-out smooth and smooth, the amount of wind decline reduces, the scope of air supply is wider, user experience is better.

Referring to fig. 6, in the cooling mode, the indoor unit 100 includes a fourth air outlet mode, in which the second air guide plate 150 is located at the arc avoidance portion 123, the first air guide plate 140 is located at the other side of the air duct 120, the first air guide plate 140 and the second air guide plate 150 form a first opening 131 and a second opening 132 closer to the air outlet 124 in the outflow direction of the air flow, and the first opening 131 is larger than the second opening 132. The first opening 131 and the second opening 132 form a horn mouth with a large inner side and a small outer side, so that cold air is intensively blown out from the second opening 132 to form fixed-point concentrated refrigeration, and the cold air can be rapidly conveyed.

In a specific selection, a user can select a required mode, namely a first mode, a second mode, a third mode or a fourth mode, through a remote controller or an APP, in other words, a cooling mode and a heating mode both have two different air-out modes, namely a rapid mode and a common mode.

In the cooling mode (heating is the same principle), the air conditioner firstly sucks a large amount of air from the room, passes through the filter screen, enters the evaporator, and simultaneously the compressor works to change the refrigerant into high-pressure gas. The high-pressure gaseous refrigerant is changed into high-pressure liquid through the condenser of the outdoor unit, and simultaneously releases a large amount of heat, then the high-pressure liquid refrigerant is changed into low-temperature low-pressure liquid through the throttling device, and finally the low-temperature low-pressure liquid enters the evaporator of the indoor unit. At this time, the refrigerant with low temperature and low pressure evaporates to absorb heat, the temperature of the air entering the evaporator is reduced, and the air is blown out through the fan blades, so that the temperature of the room is reduced.
