Abstract
The present invention relates to a blown-air directional control device for blowing out cold air from an indoor unit of a split air conditioner, and distributing the cold air in indoor space uniformly. The blown-air directional control device of the present invention comprises a plurality of transom windows and a rod, wherein the transom windows can rotate round shafts which are mutually parallel to the transom windows and are integrated with a cam; both ends of the rod are provided with holes in which connecting pins are inserted, and the rod is rotationally connected with the cam. According to the present invention, the device can reduce the cost of products by reducing the quantity of components, and can improve assembly efficiency.
Description
The present invention relates to a kind of device of detachable air conditioner indoor unit control air blow-off direction, the cold air that this device guiding blows out from indoor unit, and the cold air that blows out is distributed in the room equably, The present invention be more particularly directed to a kind of by improving the device that structure improves packaging efficiency and reduces the control air blow-off direction of product cost by the quantity that reduces assembly.
Usually, detachable air conditioner comprises an outdoor unit, indoor unit and a tube connector that is connected outdoor unit and indoor unit.Wherein outdoor unit comprises a compressor that is used for gaseous refrigerant is compressed into high-temperature high-pressure state, the heat of a gaseous refrigerant that is used for distributing HTHP also makes this gaseous refrigerant become the condenser of liquid cryogen gradually mutually, and the liquid refrigerant of phase transformation of being used for making in the condenser of a connection condenser reduces pressure into the capillary of low-temp low-pressure state.And indoor unit has one to be used for evaporating the described liquid refrigerant of just discharging so that the room keeps the evaporimeter of lower temperature from capillary by carrying out heat exchange with its surrounding air.The refrigerant of this evaporation turns back to the suction side of compressor through the refrigerant pipeline.
Fig. 1 shows the sectional drawing of detachable air conditioner indoor unit, and this indoor unit has a preceding grid 1 that is installed on housing 15 previous sections.With reference to Fig. 1, before many air intake windows 7 are contained in the grid 1, and air blow out portion 16 and be positioned in the mode that turns forward before the bottom of grid, preceding grid 1 blows out portion 16 with air and is interconnected by ventilating duct 14.
In ventilating duct 14, be provided with the room in air carry out the described evaporimeter 8 of heat exchange and by a room fan 9 that constitutes by the cross-current fan, and an aerovane 10 also is arranged in the ventilating duct 14, so that flatly to outside vent air and the discharge condensed water of deriving of indoor unit.Room fan 9 makes air enter ventilating duct 14 by preceding grid 1 and evaporimeter 8 forcibly, and makes the cold air that carries out heat exchange with evaporimeter 8 and cool off blow out part 16 by aerovane 10 and air to discharge.
With reference to Fig. 1, it is rotatable around its axle 3,3 that air blows out transom window 2,2, and the air that these transom windows are arranged on preceding grid 1 lower openings of indoor unit blows out portion 16 places, and air blows out transom window and imports cold air indoor and make this cold air in indoor even distribution.
In the control device of traditional air blow-off direction, driven wheel 4 be fixedly mounted in two air blow out transom window 2,2 two axles 3,3 one of them the axle on, and driven gear 41 be fixedly mounted in another the axle on.And be provided with an idler gear 6 between described gear 4,41, it is meshed with gear 4,41.Driven wheel is driven forward or backwards by drive motors 5 and rotates this motor and driven wheel 4 couplings.Like this, driving force has been passed to driven gear by idler gear from driven wheel.
So, when driven wheel 4 and when rotating forward or backwards according to the rotation direction of drive motors 5, rotate with the direction identical with the rotation direction of driven wheel with the driven gear 41 of idler gear 6 engagement, therefore to blow out transom window 2,2 clockwise or rotate counterclockwise round the axle of self for the air that links to each other with described gear 4,41.Like this, the gap and according to the angle of described transom window 2,2 change of cold air by 2,2 of described transom windows blows out up or down.
Yet; in traditional air blow-off direction control device; constitute described control device because the add ons of some gears and the described gear of protection must be set, therefore exist owing to the quantity that increases assembly makes the problem that product cost rises and packaging efficiency lowers.
Therefore, the objective of the invention is to provide a kind of novel air blow-off direction control device, in this device, can blow out transom window by coupling bar rather than by using gear that the driving force of drive motors is passed to air.
Another object of the present invention is the cost that will improve assembling efficiency by the quantity that reduces assembly and reduce product.
These purposes are to realize that by an air blow-off direction control device that is arranged in the split-type air conditioner device indoor unit of the present invention this device comprises: some can be around the transom window of the axle rotation that self is parallel to each other; Form and on the one end, have groove with the axle of described transom window is whole so that insert the cam of connecting pin; One porose so that the bar that inserts described connecting pin and be rotationally connected with described cam on its each termination; An axle in described axle with described transom window is connected so that control the drive motors of the angle of rotation of described transom window.
Fig. 1 is a fragmentary cross sectional view with indoor unit of traditional air blow-off direction control device;
Fig. 2 is the fragmentary, perspective view of expression air blow-off direction control device of the present invention;
Fig. 3 a schematic illustrations air blow out the closed condition of transom window;
Fig. 3 b schematic illustrations air blow out the open mode of transom window.
Now with reference to embodiment shown in the drawings the present invention is described carefully.
Fig. 2 be the expression air blow-off direction control device of the present invention fragmentary, perspective view, Fig. 3 schematic illustrations the working order of air blow-off direction control device of the present invention.The invention is characterized in to have improved and be positioned at air and blow out the structure that air in the portion 16 blows out the driving mechanism of transom window.In air blow-off direction control device of the present invention, cam the 11, the 11st, the axle 3,3 that blows out transom window 2,2 with air is integrally formed, and bar 12 is to couple together by connecting pin 13,13 and described cam 11,11 that its two ends are located.Like this, when the transom window that is connected with drive motors 5 in the transom window 2,2 rotated by the driving force of described motor 5, another transom window was also with identical direction and identical angular turn.
Fig. 3 a illustrates the closed condition that air blows out transom window 2,2.In this case, when rotating down with the effect of described axle 3 drive motors that are connected 5 with described axle 3 integrally formed cams 11, the air of bottom blows out transom window 2 and can deasil rotate round its axle 3.Simultaneously,, bar 12 links to each other, so the transom window on top also rotates round its axle 3 together with described cam because passing through connecting pin 13,13.
Then, when bar 12 arrived minimum point shown in Fig. 3 b, air blew out transom window 2,2 and peaks, therefore, by the cold air of evaporator cools by described transom window guiding and blow out portion 16 by air and blow out downwards.Aforesaid inverse operation can make described cold air upwards blow out.Promptly when drive motors 5 rotated with opposite direction, bar 12 peaked, and transom window 2,2 touches the bottom, and therefore, cold air leads downwards and blows out portion 16 by air by described transom window and blows out.
According to the invention described above, because can passing to air in the mode of connecting rod rather than use gear, the driving force of drive motors blows out transom window, so this device can reduce the cost of product by the quantity that reduces assembly, and can improve assembling efficiency.
