As shown in fig. 1 to 5, the cross-sectional profiles of the upper and lower surfaces of the baffle 330 are two arcs having the same concave direction, the connection between the baffle 330 and the rotating shaft 310 is the upper side, the cross-section of the baffle 330 is an arc structure with a wide upper part and a narrow lower part, and the arc surfaces can reduce the frictional resistance between the wind flow and the baffle.
As shown in fig. 1 to 4, an air conditioner 1000 according to an embodiment of the present invention includes a cabinet 100, an air duct 200, a flow guide device 300, an air guide flap 400, and other components not labeled.
The flow guide device 300 is arranged at the air outlet of the air duct 200; meanwhile, the guide rails 340 are disposed inside the casing 100 on both sides of the air outlet.
The upper wall of the air duct 200 is connected to the casing 100 at the air outlet in an upward inclined streamline shape, that is, the upper corner of the air outlet is an arc-shaped chamfer, so as to guide air upward and reduce the resistance of the air outlet when air is supplied upward.
The air guide swing blade 400 is arranged in such a manner that a plurality of swing blades are transversely arranged in the air duct, and the left and right wind directions are adjusted by controlling the rotation of the plurality of swing blades.
As shown in fig. 1, the air conditioner 1000 is in a shutdown state, and the air guiding device 300 is in a first state, in which the rotating shaft 310 is located at the uppermost end of the guide rail, and the air guiding plate 330 is in a closed shape at the air outlet to shield the air outlet. The length of the guide plate 330 is designed to just cover the air outlet, and meanwhile, no obvious gap is formed at the air outlet when the air conditioner 1000 is in a shutdown state, the surface of the air conditioner is streamline, and the appearance of the air conditioner is attractive.
As shown in fig. 2, when the air conditioner 1000 is turned on and enters into operation, the air guiding device 300 will move from the first state to the second state first, and the movement includes that the rotating shaft 310 starts to rotate under the transmission of the motor to drive the air guiding plate 330 to rotate upwards, and at the same time, the rotating shaft 310 moves downwards along the guide rail 340 under the transmission action until moving downwards to the middle position of the guide rail 340, at this time, the air guiding plate 330 is just opened to be approximately parallel to the axial direction of the air duct, and the air conditioner supplies air outwards at the same time.
As shown in fig. 2, at this time, the guiding device 300 is in the second state, the air flow will flow through the air inlet and the evaporator of the air conditioner from the indoor space under the action of the cross flow fan, and then flow into the air duct to be blown out after heat exchange, the guiding plate 330 in this state is equivalent to a splitter plate, the air flow is blown out from the axial direction of the air duct, the guiding device in this state is similar to a common indoor air conditioner guiding device, and the air supply direction is obliquely downward, which is not the most healthy and comfortable choice.
During the operation time of the air conditioner 1000, the rotation angle of the guide plate 330 and the height of the rotating shaft 310 can be adjusted according to the comfort requirement, and the position of the rotating shaft 310 moves downwards or upwards along with the guide plate 330 rotating upwards or downwards.
As shown in fig. 3, if the user desires to comfortably heat, the adjustable hinge 310 moves up to the upper side of the guide rail 340, and the baffle 330 is rotated downward from the second position, which is suitable for the heating mode.
As shown in fig. 3, in this state, the flow guiding direction of the flow guiding plate 330 is downward, so the wind flows downward, further, the wind channel is extended by the front flow guiding plate 330, the hot wind flow is guided to the inner wall, according to the coanda effect, the jet flow first flows to the wall along the bottom of the air conditioner casing 100, then flows to the floor along the wall, and then flows to the other side of the room along the floor, the hot air gradually floats to the activity area of the person during the movement on the floor, so that the temperature is raised from bottom to top, and the head and feet of the person are prevented from being cold while the room is warmed rapidly. Simultaneously, guide plate 330 surface is the arc design, and the air current resistance is little, and the arc design makes guide plate 330 can be better with the wind current to the inboard wall guide when the water conservancy diversion downwards, remedies the horizontal distance between air conditioner air outlet and wall, can realize blowing down hot-blastly high-efficiently, with hot-blastly attached wall send the floor to, make the room heat up from bottom to top, reduce the perpendicular difference in temperature, let the user possess better warm sufficient experience, healthy and comfortable.
If the user desires to cool comfortably, as shown in fig. 4, the adjustable hinge 310 moves down to the lower end of the guide rail 340, and the baffle 330 is simultaneously rotated upward from the second position, which is suitable for the cooling mode.
As shown in fig. 4, in this state, the guide plate 330 guides the wind upward, so that the wind blows upward, and further, the guide plate 330 extends the wind path to guide the cool wind upward to the ceiling. It is worth noting that the arc design of the surface of the guide plate 330 makes the wind flow streamline smooth and the friction resistance small; simultaneously, the arc design of guide plate 330 upper surface can make the wind current have great level acceleration forward when upwards the water conservancy diversion, the benefit of this kind of design lies in, the problem of air conditioner wind current short circuit has at first been avoided, because the air conditioner leans on the upside air inlet, excessive water conservancy diversion upwards, vertical ascending acceleration is too high can arouse air conditioner air inlet and return air short circuit scheduling problem, secondly make the wind current have great level acceleration forward when upwards the water conservancy diversion, can make the cold wind efflux reach the horizontal efflux of formation behind the ceiling, then attached ceiling flows to the room opposite side rapidly, in this in-process, cold air subsides or flows back to personnel's activity area, let personnel be in healthy comfortable low-temperature area when quick cold room, promote health and travelling comfort.
As shown in fig. 1, when the air conditioner 1000 is powered off in an operating state, the air guiding device 300 returns to the power off state from any position, in the process, the rotating shaft 310 moves up to the top end along the guide rail from any position on the guide rail 340, and meanwhile, the air guiding plate 330 is turned down and closed to cover the air outlet, and the air guiding device 300 returns to the first state.
The particular features, structures, materials, or characteristics described in this specification may be combined in any suitable manner in any one or more embodiments or examples.
The foregoing description and description of the embodiments are provided to facilitate understanding and application of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications can be made to these teachings and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty.
