Description

The current direction contraller for air of air-conditioner

The present invention relates to the current direction contraller for air of air-conditioner, particularly can convenient, accurately control the air-conditioner current direction contraller for air of discharging air-flow.

The exhaust portion of existing air-conditioner comprises that the horizontal screen 10, on the inboard of some upper and lower air discharge grilles 1 that laterally are installed in air conditioner main body 11 anterior steam vents 7 is installed in the vertical screen 9 in horizontal screen 10 the place aheads, handles vertical screen 9 and the laterally 4 contact pin 5-1 of company and the 5-2 of the stepping motor 6 of screen 10 and motor 2, vertical support stepping motor 6 and motor 2 and the drive division 3 and 4 that is connected, helps horizontal screen 10 to work with motor 2 as depicted in figs. 1 and 2.

Stepping motor 6 is connected to the end of the central shaft 9-1 of vertical screen 9.Motor 2 be connected to air discharge grille 1 inboard on the lower shaft 10-2 of the horizontal screen 10 that is connected with 10-2 of upper and lower axle 10-1 on.Mark 12 expression fans.

In this state, when the fan 12 that is positioned at air conditioner main body 11 inboards rotated, the cooling air was just from discharging between the air discharge grille 1 of steam vent 7.More than, lower shaft 10-1 and 10-2 be the center, about handle horizontal screen and be the center, go up the vertical screen 9 of lower-pilot with central shaft 9-1, just can control the direction of cold air.

At this moment, on steam vent 7 tops, vertical screen 9 is the discharge directions with the control cold air.But at steam vent bottom b, the control of the direction of cold air is not good, and this is because at steam vent bottom b, and the direction of discharging air-flow is the influence that is subjected to the design corner of main body 11 rear portion guide members more, rather than is subjected to the influence of the pilot angle of vertical screen 9.

In addition, steadily handle the air discharge grille of horizontal screen and must make in single mode, this brings difficulty with regard to the manufacturing of giving its mould.

Air-conditioning stops and when shutting vertical screen, in order to control the vertical radius of clean-up of vertical screen, and can formation one gap 8 between the top of vertical screen and the air discharge grille on the exhaust portion top.This has damaged its outward appearance, if on move the center of rotation of vertical screen so that eliminate this gap, will restive air-flow.

And in existing current direction contraller for air, vertical screen is installed separately, separates manipulation with horizontal screen, therefore is difficult to accurately control air-flow.Particularly, because vertical screen has only a wing, so air-flow can scatter and not reach at a distance.And this makes room temperature can't reach predetermined chilling temperature rapidly.

Therefore, the purpose of this invention is to provide a kind of like this air-conditioner current direction contraller for air, it can make things convenient for controls air-flow exactly, eliminate to discharge gap between air-flow control screen and the air discharge grille, and unifiedly handles horizontal screen and vertical screen, thus make cold air accurately, circulation reposefully.

For realizing purpose of the present invention, a kind of air-conditioner current direction contraller for air is provided, comprise: main body, be contained in the air discharge grille of the preceding bottom of main body and be contained on the air discharge grille inboard, be used for controlling up and down the vertical screen of airflow direction, this vertical screen has upper limb and the bottom wing that is connected with upper limb.

Preferred embodiment below in conjunction with description of drawings split-type air conditioner current direction contraller for air of the present invention.

Referring to Fig. 3,4 and 5, current direction contraller for air structure of the present invention makes and comprises a vertical screen 40 that is contained in air discharge grille 20 inboards in air conditioner main body 30 front and rear parts and laterally be installed in some horizontal screen 50 on the vertical screen 40.

In order to reduce to discharge scattering of cold air, vertical screen 40 has two kinds of wings, i.e. upper limb 41 and greater than half bottom wing 42 of upper limb.Last bottom wing 41 is preferably identical with 42 shape.The center of rotation 43 of vertical screen 40 is positioned at a side of upper limb 41.With on support chip 44 and the bottom wing 42 that center of rotation 43 is connected, laterally be formed with some perforation 42a at certain intervals, so that be connected with horizontal screen 50.In end one support portion 45 is arranged, a pair of projections 47 and a hole 46 are arranged on this support portion 45 with down sincere 42 support chips that are connected 44.

Central authorities at the horizontal screen 50 that is connected with vertical screen 40 are formed with slit 53.One locating shaft 52 is arranged on slit 53 inboards, and it inserts among the hole 42a on vertical screen 40 bottom wings and supported by it.One axial hole 51 is arranged on the offside of the peristome of slit 53, and the driving shaft 54 that is started by micromotor 80 inserts in this hole.

Except vertical and

horizontal screen

40 and 50 be connected, vertically on the side of screen 40 gripper shoe 60 is housed also.One jack 61 is arranged on the gripper shoe, be connected with the center of rotation of vertical screen 40 upper limbs 41, be used for handling in a stepping motor 70 these jacks 61 of insertion of this vertical screen 40.The both sides of jack 61 respectively have a boss 70 to insert in this jack 61.Respectively there is a boss 62 on the both sides of jack 61, thereby support stepping motor 70 with screw 72.Also has a deep-slotted chip breaker 63 on the gripper shoe 60, it is connected on the boss 47 with screw 82, thereby rotate an angle along with the rotation of vertical screen 40, under this state, micromotor 80 is connected with the driving shaft 54 that horizontal screen 50 is handled in the hole 46 and being used for of support portion 45 on passing vertical screen 40 bottom wings 42 1 sides.Mark 71 and 81 expression circular support sheets.Mark 83 is for being connected to the lead of micromotor 80.

In said structure, in order steadily to control air-flow under vertical screen 40 raised states, the bottom wing 42 of vertical screen 40 can't scatter the air-flow of discharge.In other words, owing to moved up and down along the deep-slotted chip breaker on the gripper shoe 60 by the vertical screen 40 of lower-pilot on the stepping motor 70, therefore the air-flow of discharging is controlled, and bottom wing 42 can't scatter the air-flow of discharge.

Simultaneously, be inserted in driving shaft 54 in the axis hole 51, that handle by micromotor 80 and make the horizontal screen move left and right that is contained on the bottom wing 42.

The direction of the inner air-flow that also passes through steam vent 90 discharges that produces of air-conditioner is by the upper limb 41 on steam vent 90 tops and bottom wing 42 controls of steam vent 90 bottoms.The upper and

lower wing

41 and 42 is made identical shaped, and air-flow just can be controlled on the same direction.

Vertical and

horizontal screen

40 and 50 about on the same position, about control, thereby air-flow can be more concentrated, controlled more accurately.

Gap between air discharge grille 20 and the vertical screen 40 is eliminated, thereby has solved the defective of outward appearance aspect.The shape of the air discharge grille of air-conditioner obtains simplifying, thereby has reduced the production cost of making its mould, and is easy to make.

As mentioned above, the invention provides a kind of air-conditioner current direction contraller for air, it can control air-flow easily and accurately, eliminate to discharge the gap between air-flow control screen and the air discharge grille and unifiedly handle vertical and horizontal screen, thus make cold air accurately, circulation reposefully.Therefore, the present invention has overcome following defective very effectively, has been difficult to make the mould of air discharge grille, has stopped and form a gap for the vertical radius of clean-up of controlling vertical screen between vertical screen and air discharge grille when closing vertical screen when air-conditioner.And the outward appearance of bringing is not good, when moving the Mobility Center of vertical screen in order to eliminate this gap restive air-flow and since vertical and horizontal screen be installed separately and manipulation thereby restive air-flow.
