Abstract

The utility model relates to a wind direction turning device. The utility model is characterized in that the wind direction turning device is composed of a bidirectional and synchronous motor, a control disc, a wind guiding board, and a micro switch. The end of the bidirectional and synchronous motor whose turning is changed by impedance torsion is provided with the control disc, the upper end of the control disc is fixed with the wind guiding board, the outer end of the control disc is provided with the micro switch, the motor is driven by the micro switch, and the wind guiding board is turned. The turning and rotation of the motor are really and automatically changed by the interaction of the resistance force and the control disc.

Description

The wind direction slewing gear

The utility model relates to a kind of wind direction slewing gear, refers to a kind of device that can adjust the rotation of conversion wind direction automatically especially.

Generally selecting wind apparatus is that air opening end at the air blast parts is provided with a guide duct, so that air-flow connects the position to needs, if, air supply position demand difference, several guide ducts then need be set to required position respectively, respectively at each position installing controlling component, use again with the derivation supply of control air-flow; This public blast device in air port that has more is controlled inconvenience, and manufacture cost is too high.

The purpose of this utility model is that a kind of wind direction slewing gear will be provided, and adopts bi-directional synchronization motor control one control panel automatically.Wind deflector is diverted to needs the position.

The purpose of this utility model is achieved in that the wind direction slewing gear fixedly installs a control panel at the rotating shaft end of a two-way syncmotor, at control panel Zhou Duan recessed drive hole is arranged, establish several sensitive switches in the control panel outer end, pass the control panel upper end at motor shaft and connect an extension bar, and at fixing axle head fit one wind deflector of extension bar front end, be located at two direction ends of air blast knockdown export by wind deflector, make motor control wind deflector cover air blast through the interactive widely different road of sensitive switch and be exported to lower end honeycomb duct or horizontal side honeycomb duct.

Owing to adopt such scheme, the utility model wind direction capable of automatic changing rotates, and by a two-way syncmotor, and cooperates the number sensitive switch can make wind deflector by the different requirements of using, and is adjusted to the appropriate location respectively; Not only save material, simplified structure, and can remove from manually-operated loaded down with trivial details, the efficient height.

Below by accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the utility model example structure exploded view.

Fig. 2 is the utility model embodiment combination section.

Fig. 3 is that the utility model embodiment uses schematic representation.

Fig. 4 is that the utility model embodiment moves schematic representation.

Fig. 5 is that the utility model embodiment moves schematic representation.

Fig. 6 is the utility model embodiment circuit diagram.

Among the figure: 1 bi-directional synchronization motor, 11 rotating shafts, 2 control panels, 21 drive holes, 3,3A, 3B, 3C sensitive switch, 3B ₁, 3C ₁Lever, 3B ₂, 3C ₂Point, 4 extension bars, 41 stationary axle, 5 wind deflectors, 6 air blast, 61 outlets, 62,63 honeycomb ducts, 7 handles, AC power supplies, NO often opens, and NC is normally closed, the COM contact.

Referring to Fig. 1,2; The utility model embodiment is made up of a two-way syncmotor 1, a control panel 2, a wind deflector 5 and number

sensitive switch

3A, 3B, 3C.Rotatingshaft 11 ends at a two-way syncmotor 1 are fixed a control panel 2, the recessed drive hole 21 that is provided with at control panel 2 all ends places, be provided with several sensitive switches 3 in control panel 2 outer ends, pass control panel 2 upper ends in motor 1 rotating shaft 11 and connect an extension bar 4, establish a stationary axle 41 again at extension bar 4 front ends, with socket one wind deflector 5, the contact of sensitive switch 3 is connected respectively to power supply and bi-directional synchronization motor 1 end, promptly constitute an automatic blast device that changes wind direction.

Shown in Fig. 3-6; Wind deflector 5 is located at outlet 61 ends of an air blast 6, and export 61 honeycomb ducts 62 that have more than two, 63, present embodiment is the dual gas-supplying structure of a hand dryer or blower, it promptly can be used for room heater for the baking hand or after installing hot air apparatus additional at outlet 61 lower end honeycomb ducts 62, honeycomb duct 63 in a horizontal side promptly supplies to connect leader 7, for connecting air-flow to the position end that needs, it is when general the use, wind deflector 5 is positioned at the position of capping horizontal side honeycomb duct 63, when the user picks up handle 7, because of the position end system of fixed handle 7 buries a sensitive switch 3A underground, its normality contact COM connects to electric AC end (Fig. 6), the Chang Kaiduan NO of normally closed another sensitive switch of NC end conducting 3B of sensitive switch 3A, make 1 entry into service of bi-directional synchronization motor, clockwise rotate earlier when starting because of it, so be stuck in horizontal side honeycomb duct 63 ends because of wind deflector 5, and make bi-directional synchronization motor 1 produce counter-rotating, make wind deflector 5 be driven by it the face inhour and rotate to lower end honeycomb duct 62 positions (Fig. 5) and stop, and make the drive hole 21 of control panel 2 turn to the lever 3B of sensitive switch 3B simultaneously ₁End, some 3B ₂End makes sensitive switch 3B cut off the electricity supply, and when tool hot blast structure, begins to make air blast 6 to produce mass air flow, and handle 7 ends are exported to the position that needs use.

When hanging up handle 7, the Chang Kaiduan NO conducting of sensitive switch 3A is to another sensitive switch 3C, and turning to when making bi-directional synchronization motor 1 be subjected to last release changes over counter-rotating voluntarily, and makes wind deflector 5 go back to horizontal side honeycomb duct 63 ends, and arrives the lever 3C of back, location with seasonal sensitive switch 3C ₁End, some 3C ₂Hold, also be arranged in the drive hole 21 of control panel 2, and the power supply of cut-out bi-directional synchronization motor 1 stops the action of wind deflector 5, and guarantee that wind deflector 5 positions can not move to end in addition, make air-flow correctly be directed to the position of demand by mistake.

Claims

A kind of wind direction slewing gear, it is characterized in that: the rotating shaft end at a two-way syncmotor fixedly installs a control panel, at control panel Zhou Duan recessed drive hole is arranged, establish several sensitive switches in the control panel outer end, pass the control panel upper end at motor shaft and connect an extension bar, and at fixing axle head fit one wind deflector of extension bar front end, be located at two direction ends of air blast knockdown export by wind deflector, make motor control wind deflector cover air blast through the interactive widely different road of sensitive switch and be exported to lower end honeycomb duct or horizontal side honeycomb duct.
