The invention mainly provides an air guide device which is mainly applied to a cabinet air conditioner, so that an air supply mode of the cabinet air conditioner is increased, a non-wind-sense air supply function is provided for the cabinet air conditioner, and a user can enjoy soft wind under the condition of meeting the requirement of the user on temperature regulation and control, so that the user experience is improved. The cross-flow wind wheel 300 of the cabinet air conditioner is arranged in an air duct between the air inlet 110 and the air outlet 120, and the heat exchanger 400 of the cabinet air conditioner is arranged in the shell around the cross-flow wind wheel 300 and corresponds to the air inlet 110. The outlet 110 extends along the height direction of the housing 100.
The following will mainly describe a specific structure of the air guide device.
Referring to fig. 1 to 4, in an embodiment of the present invention, the air guiding device 200 is used for an air conditioner, and the air guiding device 200 includes:
the air guide grille 210 is provided with an air guide plate for guiding airflow to flow on the air guide grille 210;
the windless guide plate 220 is provided with a guide piece for reducing the wind speed on the windless guide plate 220;
the air guide grilles 210 and the no-wind guide plates 220 are arranged side by side, and gaps are formed between the air guide grilles 210 and the no-wind guide plates 220.
Specifically, in the present embodiment, the air deflector is disposed along the length direction of the air guide grille 210, and when the air flow passes through the air guide grille 210, the air flow flows along the plate surface of the air deflector. The windless deflector 220 takes an arc-shaped deflector as an example, a deflector is arranged on the windless deflector 220, the shape and size of the deflector are not specially limited, and only the wind speed can be reduced. The air guide piece takes the air guide ribs as an example, and a plurality of air guide ribs surround to form a plurality of air passages communicated with the air conditioner and the air passage outside the air conditioner. The airflow passes through the duct to the user-designated area. Wherein the wind tunnel may have a bend, i.e. to guide the airflow channel and reduce the wind speed by changing the flow direction of the wind tunnel. Of course, in some embodiments, a plurality of flow-limiting holes penetrating through the surface of the no-wind guide plate 220 may be formed on the no-wind guide plate, so that the wind speed is reduced when the airflow passes through the flow-limiting holes, and the wind volume is reduced when the airflow passes through the no-wind guide plate 220. The aperture of the air inlet end of the flow limiting hole is smaller than that of the air outlet end of the flow limiting hole, so that the flow limiting hole becomes a speed reducing hole.
The air guide grille 210 is arranged in an arc shape, the airless guide plate 220 is arranged in an arc shape, and after the air guide grille 210 and the airless guide plate 220 are arranged side by side along respective length directions, one sides of the air guide grille 210 and the airless guide plate 220 are connected with each other, and a gap is formed between the other sides. The air guide grids 210 and the windless guide plates 220 enclose a guide cavity 240, the guide cavity 240 is arranged along the length direction of the air guide grids 210 and the windless guide plates 220, and the guide cavity 240 is provided with an air inlet 230 arranged along the length direction of the air guide grids 210. At this time, the first sidewall of the diversion cavity 240 is formed by the air guiding grilles 210, the second sidewall is formed by the no-wind diversion plates 220, and the remaining portion around the diversion cavity 240 except the first sidewall and the second sidewall is the air inlet 230 (which is a gap between the air guiding grilles 210 and the no-wind diversion plates 220).
At this time, the air flow may enter the diversion cavity 240 defined by the air guiding grilles 210 and the no-wind diversion plates 220 through the air inlets 230 (gaps) and flow out of the area from the air guiding grilles 210, and of course, the air flow may also enter the diversion cavity 240 from the air guiding grilles 210 and then flow out of the no-wind diversion plates 220. In the above process, the air flow direction is not changed, and the positions among the air guide grille 210, the no-wind guide plate 220 and the air inlet 230 are changed by rotating the air guide device 200. When the airflow enters the diversion cavity 240 from the air guide grille 210 and flows out of the diversion cavity 240 from the no-wind diversion plate 220, the secondary diversion deceleration of the air guide grille 210 and the no-wind diversion plate 220 is realized, and the no-wind effect is improved.
Of course, in some embodiments, the positions of the air guiding grille 210, the no-wind deflector 220 and the air inlet 230 may be maintained, and the air supply in different modes may be realized by changing the flow direction of the air flow. At this time, the purpose of changing the flow direction of the air flow is achieved by adding a wind shield to switch the flow channel of the air flow. The wind shield has a plurality of positions, each different position corresponds to an air duct, one air duct is communicated with the air inlet 230 and the no-wind guide plate 220, the other air duct is communicated with the air inlet 230 and the wind guide grille 210, and the other air duct is communicated with the wind guide grille 210 and the no-wind guide plate 220. Therefore, different air ducts can be formed by controlling different positions of the wind shield, and different air supply modes can be realized.
Of course, in some embodiments, the air guiding grille 210 and the no-wind guiding plate 220 may not enclose the air guiding cavity 240, and in different modes, only the air supply mechanism in the corresponding mode needs to be moved to the air outlet 120. For example, when the air is supplied in a normal air supply, the air guide grille 210 is disposed corresponding to the air outlet 120, and when the air is supplied without wind sensation, the air guide plate 220 is moved to be disposed corresponding to the air outlet 120.
In this embodiment, the air guide grille 210 and the no-wind guide plate 220 are arranged side by side at intervals, so that the air guide device 200 can perform ordinary air supply and no-wind-sense air supply according to the needs of a user, when the temperature in a room is close to or reaches the preset temperature of the user, the no-wind guide plate 220 is arranged corresponding to the air outlet 120, so that the air flow passing through the air guide device 200 is softer, and when the air flow blows to the user, the user feels more comfortable.
In order to improve the wind-guiding and speed-reducing capacity of the wind-guiding grille 210, the grid wind-guiding grille further comprises a wind-guiding frame, the wind-guiding plate is arranged in the wind-guiding frame, and two ends of the wind-guiding plate are rotatably connected with the wind-guiding frame.
Specifically, in this embodiment, the air guide frame is a rectangular frame formed by splicing a plurality of horizontal frame strips and vertical frame strips. The quantity of aviation baffle is many, and many aviation baffles are arranged along the length direction of horizontal frame strip, and each aviation baffle sets up along the length direction of vertical frame strip, has seted up the commentaries on classics hole on the horizontal frame strip, and the both ends of aviation baffle insert in the commentaries on classics hole for aviation baffle and horizontal frame strip rotate to be connected. The air deflector is driven by a motor, and the motor is electrically connected with a control device of the air conditioner.
In order to improve the non-wind effect of the non-wind deflector 220, the wind guide member includes a plurality of flow guide holes penetrating through the non-wind deflector 220, and the plurality of flow guide holes are arranged on the non-wind deflector 220. The aperture of the air inlet section of the diversion hole is smaller than that of the air outlet section of the diversion hole, and the diversion hole is arranged from the air inlet end to the air outlet end in a gradually expanding manner. So set up for the air current can be steady, the deceleration passes the water conservancy diversion hole. When the airflow passes through the flow-limiting hole, the wind speed is reduced, and due to the blocking effect of the plate surface, the wind quantity on the windward side of the windless guide plate 220 is larger than that on the leeward side, namely when the airflow passes through the windless guide plate 220, the wind quantity is reduced. That is, the windless deflector 220 slows down the wind speed and reduces the wind volume, so that the wind blowing to the user is softer and more comfortable.
In order to improve the non-wind effect, the wind guide device 200 is annularly arranged; the windless guide plate 220 is a long strip-shaped plate arranged in an arc shape in the width direction;
the air guide grille 210 is a strip-shaped grille which is arranged in an arc shape in the width direction;
one side of the no-wind guide plate 220 is fixedly connected with one side of the wind guide grille 210.
Specifically, in this embodiment, the air guiding frame of the air guiding grille 210 is disposed in an arc shape, and specifically, the transverse frame strip is disposed in an arc shape. The radian of the width direction of the windless deflector 220 is equivalent to the radian of the length direction of the transverse frame strip. One side of the windless deflector 220 is fixedly connected to a longitudinal frame strip, and the connection manner may be various, such as a buckle, a screw, and an adhesive. Of course, in some embodiments, the airless deflector 220 and the air guide frame are integrally formed. When the air deflector does not rotate relative to the air guide frame, the no-wind deflector 220 and the air guide grid 210 can be integrally formed.
In some embodiments, in order to generate a better non-wind effect, the extending direction of the width of the wind guide grille 210 and the extending direction of the width of the non-wind guide plate 220 are located on the same ellipse or circle.
Wherein, the circumferential angle corresponding to the width direction of the windless deflector 220 is 90-150 degrees;
the circumferential angle corresponding to the width direction of the air guide grille 210 is 90-150 degrees.
The width of the no-wind guide plate 220 and the width of the air guide grille 210 are extended in the same circumferential direction. At this time, the radian of the width direction of the calm guide plate 220 is the same as the radian of the width direction of the air guide grille 210, a fan shape is formed by connecting the two ends of the width direction of the calm guide plate 220 with the center of a circle, the central angle of the fan shape is 90-150 degrees, taking 120 degrees as an example. Similarly, the two ends of the air guide grid 210 in the width direction and the connection line of the circle center form a fan shape, the central angle of the fan shape is 90-150 degrees, and 120 degrees is taken as an example. At this time, the central angle corresponding to the gap between the air guide grille 210 and the no-wind guide plate 220 is also 120 °. Of course, the angle can be adjusted and set according to actual needs.
Referring to fig. 5 and 6, in order to improve the connection strength between the airless deflector 220 and the air guide grill 210, the air guide device 200 further includes an annular reinforcing rib 250. The radian of the joint of the annular reinforcing rib 250 and the air guide grille 210 is equivalent to the radian of the air guide grille 210 in the width direction. The radian of the joint of the annular reinforcing rib 250 and the airless deflector 220 is equivalent to the radian of the width direction of the airless deflector 220.
Specifically, in the present embodiment, the annular reinforcing rib 250 is provided on the inner wall surface of the guide chamber 240 along the calm guide plate 220 and the guide grill 210. The outer wall surface of the annular reinforcing rib 250 is attached to the surface of the airless deflector 220 and is fixedly connected with one side of the air guide grid 210 facing the deflector cavity 240. Of course, the annular reinforcing rib 250 can be fixed to the airless deflector 220 and the air guide grille 210 in many ways, such as by a snap connection, a screw connection, etc. Taking the case that the no-wind guide plate 220 and the wind guide grille 210 are provided with the slots, the annular reinforcing ribs 250 are clamped in the slots.
When the wind guide device 200 is subjected to an external load (a rotation load or an extrusion load of the wind guide device, etc.), the load borne by the airless guide plate 220 and/or the wind guide grid 210 is transmitted to the annular reinforcing ribs 250, the reinforcing ribs 250 elastically deform to bear the load, and when the load of the airless guide plate 220 and/or the wind guide grid 210 is withdrawn, the reinforcing ribs 250 recover the elastic deformation to transmit the force of the internal deformation to prepare for bearing next time. Through the arrangement of the annular reinforcing ribs 250, the bearing capacity of the air guide assembly 200 is greatly improved.
