Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Preferred embodiment one:
This preferred embodiment provides a kind of air-cooled ducted air conditioner tuyere device.As shown in Figure 1, this tuyere device comprise installing frame assembly 1, the return air frame 2 be connected in installing frame assembly 1; Be arranged on the driving box 3 on return air frame 2, the outer panels 5 of wainscot 4 that cross section is arch and tabular.
Wherein, installing frame assembly 1 comprises the installing frame of hollow and the bracing frame be connected on installing frame two sides; Installing frame is connected to the discharge pipe port of air-cooled ducted air conditioner and can be embedded in the installed surface such as body of wall or ceiling, for fixing tuyere device; Bracing frame is used for the side of firm installing frame; Return air frame 2 is for fixed drive box 3; Drive box 3 to comprise the connecting rod that can bend and stretch, the termination of connecting rod to be connected on wainscot 4 and wainscot 4 and outer panels 5 can be driven to move, and controls the folding in air port; Be connected in outer panels 5 edge movable of wainscot 4.
The pre-buried mounting means of installing frame assembly 1 to ensure after tuyere device integral installation with metope or ceiling, without difference in height, not affect indoor finishing effect, easy accessibility; Towards periphery whether wainscot 4 and outer panels 5 be closure or openness under the drive driving box 3, control to blow in environment, avoid panel be in normally open and cause dust accretions or foreign matter to enter; Wainscot 4 is flexibly connected with outer panels 5, easy accessibility, can change the color, pattern, material, shape etc. of outer panels 5 according to the hobby of interior decoration style or user.
As shown in Figures 2 and 3, a lateral edges of wainscot 4 stretches out and forms clamping limit 41, and relative opposite side edge forms resilient clamp member 42; On panel 5, the position on corresponding clamping limit 41 is provided with grab 51 outside, and the position of corresponding resilient clamp member 42 is provided with arrow shaped Elastic buckle 52.Multiple clamping, fastening structure ensure that panel is indeformable.
During installation, first clamping limit 41 is snapped in grab 51, then resilient clamp member 42 is aimed at Elastic buckle 52, pressed, together with being connected to wainscot 4 and outer panels 5 i.e. firm stable.First Elastic buckle 52 extracted from resilient clamp member 42 during dismounting, again grab 51 taken down from clamping limit 41.
In order to can installation panel more quickly, wainscot 4 be provided with stopper slot 43, panel 5 be provided with the spacing block set 53 suitable with stopper slot 43 outside.First stopper slot 43 and spacing block set 53 are alignd, resilient clamp member 42 and Elastic buckle 52 are more easily aimed at.
In order to improve intensity, wainscot 4 is provided with the reinforcement 44 that many transverse and longitudinals intersect.This structure also has anti-condensation effect simultaneously.
Panel adopts inside and outside two-layer structure and the cross section of wainscot 4 is domes, then form a cavity between wainscot 4 and outer panels 5, this structure is conducive to the generation preventing condensation, and integrally-built intensity is larger, is not easily damaged.
As shown in Figure 4, drive box 3 to be arranged on return air frame 2, stepper motor 32 protrudes from outside the side of return air frame 2.Annexation between driving box 3 and wainscot 4 as shown in Figure 5.
As shown in Figures 5 to 7, drive box 3 comprise hollow open mounting box 31, be arranged on stepper motor 32 outside mounting box 31, be arranged on gear train inside mounting box 31, be connected to shrinking connecting-rod group on gear train and swivel link group and be fastened on the lid 33 of opening part of mounting box 31.Gear train is connected on the axle of stepper motor 32, can rotate under the driving of stepper motor 32, and then drives shrinking connecting-rod group and the motion of swivel link group.
Shrinking connecting-rod group comprises the first connecting rod 34 and second connecting rod 35 that are hinged, and the free end of first connecting rod 34 forms the first gear end 341 be meshed with gear train, and the free end 351 of second connecting rod 35 is connected to panel; First connecting rod 34 can drive second connecting rod 35 to move under the drive of gear train, second connecting rod 35 and then folding panel.
Swivel link group comprises the third connecting rod 36 and double leval jib 37 that are hinged.The free end of third connecting rod 36 forms panel jointed shaft 361, and it is outer and be connected on panel by articulated section 49 that panel hinged axle 361 is exposed to lid 33 from lid opening 331.The free end of double leval jib 37 forms the 4th gear end 371 be meshed with gear train; Double leval jib 37 can drive third connecting rod 36 protruding under the drive of gear train, and now panel hinged axle 361 rotates in articulated section 49.In order to ensure that panel in the on state can be more stable, mounting box 31 inside is provided with the position limiting structure of third connecting rod 36.When third connecting rod 36 be in stretch out state time, this position limiting structure ensures that third connecting rod 36 can not swing on the direction being parallel to installed surface, and then ensure that panel assembly can not swing on the direction being parallel to installed surface.
In order to reduce the power that the first gear end 341 is born, spring 342 being set on the body of rod of first connecting rod 34 and between the outer wall of mounting box 31, sharing the power in the first gear end 341.
When first connecting rod 34 and second connecting rod 35 are in deployed condition, in Fig. 5, the right side of wainscot 4 is opened outward; Now double leval jib 37 also drives third connecting rod 36 to the limit, left side of extrapolated side board component, and panel is opened, blown in environment; When first connecting rod 34 and second connecting rod 35 are in rounding state, double leval jib 37 also drives third connecting rod 36 to be recovered in mounting box 31, and wainscot 4 is closed to return air frame 2 place, and panel is closed, without air-supply.Because the length of the connecting rod of both sides is different, be skewed relative to installed surface when panel assembly is opened.
Gear train comprises master gear 38, first driven gear 391 and the second driven gear 392.Wherein, master gear 38 is arranged on the axle of stepper motor 32, and the first driven gear 391 is meshed with master gear 38 and the first gear end 341 respectively, and the second driven gear 392 and the first gear end 341 are coaxially fixed and be meshed with the 4th gear end 371.
During work, stepper motor 32 drives master gear 38 to rotate, and master gear 38 drives the first driven gear 391 to rotate, and the first driven gear 391 and then drive the first gear end 341 are rotated, and first connecting rod 34 launches or draws in; Second driven gear 392 rotates with the first gear end 341 and then drives the 4th gear end 371 to rotate, and double leval jib 37 drives third connecting rod 36 to move.
This tuyere device installation process: outer panels 5 snapped fit onto on wainscot 4, is connected on wainscot 4 by the free end 351 and panel hinged axle 361 that drive box 3, is arranged on return air frame 2 by driving box 3, then is snapped in installing frame assembly 1 by return air frame 2.
During maintenance, return air frame 2 and driving box 3, wainscot 4, outer panels 5 entirety are extracted; When outer panels 5 changed by needs, other assembly of this tuyere device need not be moved, directly outer panels 5 is pulled down from wainscot 4.
