Description

Multi-functional tuyere device

Technical field

The utility model relates to ventilation unit, in particular for the tuyere device of air-conditioning system.

Background technology

Existing air conditioning air outlet is general simple as cold and hot gas communication mouth, as wants to control air switch, need add the airduct valve in addition.For attractive in appearance, the common decorated material of airduct valve blocks, in case break down, can't overhaul.A kind of air port, valve two-in-one type tuyere device are arranged at present, and it rotates the control air switch by the driver drives valve disc, but the driver complexity of this kind tuyere device, volume big, be not easy to install, price is higher simultaneously.Other has a kind of tuyere device of directly controlling air switch by the air port blade rotation, it drives rocking bar by synchronous motor and rotates, and drive air port blade folding, by blade two ends mechanical limit switch control location, though this kind air port price is lower, but failure rate of machinery is higher, and has the bigger problem of volume equally.

Summary of the invention

The purpose of this utility model provides a kind of wind efficient height, simple in structure, multi-functional tuyere device of being easy to installation and maintenance and maintenance transferred.

Said tuyere device is by blinds, support the frame of blinds and drive the motor drive mechanism composition that blinds rotates, it is characterized in that: many preceding blinds 14 of layout parallel to each other are about the preceding blinds balance staff 13 at its two ends is loaded on or on a pair of up and down blinds frame 12, one end of preceding blinds balance staff is meshed with the one side of first tooth bar 6, the another side of first tooth bar is meshed with main drive gear 9, and the power shaft of main drive gear links to each other with the power output shaft of stepper motor 8; After many of layout parallel to each other blinds 4 through blinds maintenance axle 2 behind its two ends be loaded on another to blinds frame 12 on; The dislocation of forward and backward blinds is vertical installs, and four blinds frames are assembled into one through connecting elements-four connecting plate 15, four right angle connecting plates 1.Blinds and back blinds cross section are curved before said, and hollow is filled with the expanded material that is used to increase its intensity in the cavity.Said blinds frame 12 cross sections are L-shaped, stagger up and down mutually with the position of row's pin-and-hole that preceding blinds balance staff 13 is installed in the position of row's pin-and-hole of installation back blinds maintenance axle 3; Louver end part can drive it and rotate the one side engagement of balance staff end face and tooth bar before one end of preceding blinds balance staff inserted.At said first tooth bar one side of driving gear is housed, the position limited gear 7 that is meshed with it also is housed, position limited gear is meshed with transition gear 5 simultaneously, and transition gear is meshed with second tooth bar 20, and first tooth bar is coaxial with second tooth bar.

Said tuyere device is in diverse location by stepper motor driven wheel rack drives air port blade, not only can make the air port or open or close, also can regulate the air port blade angle to change wind direction, can also make simultaneously blade keep the air-out air-flow of central air conditioner system being evenly distributed toward anti-swing.As this device is used for the top to canyon, alternative air diffuser commonly used at present, because hot gas rising cold air descends, should the blade tuning is vertical in winter, be convenient to hot blast and can blow lowlyer, the room upper and lower temperature difference is diminished.Summer is opposite, should make blade lean, and cold air is not directly blown down, but descends naturally.The arc hollow blade has light weight, the advantage that bending strength is high.This device transfer wind efficient height, simple in structure, be easy to installation and maintenance and maintenance.

Embodiment

Stepper motor is by additional controller control.Controller can be provided with manually and automatic two kinds of modes of operation, and controller is made up of integrated chip, also can be with temperature sensor, the speed governing relay.The automatic transmission course of work is: start, stepper motor 8 rotates counterclockwise drive main drive gear 9 and rotates counterclockwise, first tooth bar 6 moves right, blinds balance staff 13 clockwise rotates before driving, the air port blinds that drives thus on it is opened, as contain the swing instruction, and just stepper motor enters the commutation rotation period after rotating counterclockwise a period of time, blinds swing before driving.Subsidiary action comprises that also the rate of change relay correspondence opens the speed-changing draught fan coil pipe, and relay is opened the hot water pipe magnetic valve.Mouthful to canyon,, can drive 20 motions of second tooth bar through transition gear 5 as against the wind, do the symmetry motion thereby drive second half preceding blinds by position limited gear 7 in order to make the blinds symmetric motion.After operator scheme was set, the Push And Release of blinds also can be controlled by temperature.

Back blinds 4 can be used for regulating wind direction and air quantity size.Back blinds is positioned on the blinds frame 12 through maintenance axle 3 and maintenance rubber ring 2, and covering can be fixing with the various gears on the blinds frame, tooth bar and various axle behind the side cover plate 16.Right angle connecting plate 1, connecting plate 15 are connected into square frame with four blinds frames.Side at the L-shaped blinds frame contact air-flow of said cross section is provided with groove, is filled with the heat-insulation layer 21 that heat preserving and insulating material is made in the groove, and this kind design can be eliminated facial dewfall phenomenon, and the facial temperature in air port is diminished with the difference of environment temperature, is difficult for uncovering.
