Abstract
The present invention discloses an indoor unit of an air conditioner. An air blower, a heat exchanger and a water discharging chassis are arranged in a body, the front lower part of the body is provided with an air suction inlet, and the front upper part of the body is provided with an air exhaust opening. The upper part of the air exhaust opening is provided with an exhaust opening unit which can lift and descend. A plurality of leading screws are arranged on the exhaust opening unit at intervals to lift and descend the exhaust opening unit. Therefore, the gravity center of the exhaust opening unit is stable, the swing degree of the exhaust opening unit is reduced, and the exhaust opening unit can stably lift and descend.
Description
Technical field
The present invention relates to a kind of exhaust unit lifting control device of air conditioner room unit, specifically be that the exhaust unit on a kind of indoor machine of air-conditioner main frame top has a plurality of leading screws control liftings, thus the indoor machine of air-conditioner of stability when improving the exhaust unit lifting.
Background technology
In general, for more comfortable environment is provided to the user, the freeze cycle that the air-conditioner utilization is made of compressor, condenser, expansion gear, evaporimeter is carried out the cooling-heating room operation or is purified air indoor.Roughly can be divided into detachable air conditioner and integral air conditioner
Detachable air conditioner is identical on function with integral air conditioner.But detachable air conditioner at the outdoor off-premises station that is provided with heat release/cooling and compression function, connects two devices that separate at the indoor indoor set that is provided with cooling/heat release function with the refrigerant comb.Integral air conditioner is that cooling, heat release, compression function are integrated, and the wall in the house burrows or after hanging up device on the window, directly is provided with.
As shown in Figure 9, the front lower of the indoor machine of air-conditioner of prior art has formed air suction inlet 101a; Front upper has formed air outlet 102a; Heat exchanger 120 and pressure fan 130 have been installed in inside.
A plurality of decoration grids 105 are installed on the indoor set, decorate grid 105 protection air outlet 102a inside.
In the aforesaid indoor machine of air-conditioner, when pressure fan 130 drives,, after heat exchanger 120 cooling, discharge to the place ahead, top of indoor set by air outlet 102a by air suction inlet 101a inhaled air.
On the other hand, in the indoor machine of air-conditioner, during the height of up-down adjustment air outlet 102a,, can effectively carry out convection current to cold air or hot gas according to the structure that is provided with of personnel, furniture or equipment in the size of the interior space of cold/greenhouse, its space.
As an example of the air outlet 102a position of as above up-down adjustment indoor machine of air-conditioner, the indoor machine of air-conditioner of the decoration grid that has elevating function of the Korean registered patent No. 0249375 is arranged.
The air-conditioner that has elevating function, as shown in figure 10, by constituting as the lower part: the front lower of indoor set is formed with air suction inlet, and inside is equipped with the body 101 of air treatment system; Discharge is treated air in body, i.e. the upper decoration grid portion 102 of the air outlet of cold air or wet; Between body 101 and decoration grid portion 102, the connecting portion 103 that prolongs to body 101 from the bottom of decorating grid portion 102.
The back of body 101 is provided with the leading screw 108 of side's prolongation vertically upward; Leading screw 108 is connected to the motor shaft of lower end drive motors by dicyclo 114; Decorate and be provided with the screw set 109 that coincide with leading screw 108 in the grid portion 102.
Have in the air-conditioner of elevating function, when drive motors rotated, leading screw 108 began rotation; Decorate grid portion 102 and rise to the upside of body 101 along the direction of rotation of leading screw 108, at this moment, the height of air outlet will change.
But, in the prior art indoor machine of air-conditioner, lean on a pair of leading screw 108 and screw set 109 liftings because of decorating 102 in grid portion, what decoration grid portion 102 can not be stable is supported, rocks easily during lifting; Owing to, have the long not enough point of lifting time only by a pair of leading screw 108 and screw set 109 liftings.
Also have, for rocking of preventing, and other and screw set 109 is other when other guide post is set at leading screw 108, makes its structure become complicated, and has the not enough point of expense increase.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of exhaust unit stable elevation, rising or falling speed indoor machine of air-conditioner faster more of discharging heat exchange air that makes is provided.
Include in order to solve the problems of the technologies described above indoor machine of air-conditioner of the present invention: its body is built-in with pressure fan, heat exchanger, drain underpan; Its front lower is formed with air suction inlet; Front upper is formed with air outlet; On the top of outlet liftable exhaust unit is set; Be characterized in exhaust unit keep at a certain distance away be provided with can lifting two or more leading screws of exhaust unit.
Described indoor machine of air-conditioner also includes the whirligig that can rotate two or more leading screws simultaneously.
Described whirligig is arranged between two or more leading screws, with the central gear of these leading screw engagements; Axle is provided with the motor of central gear.
The number of teeth of the gear ratio leading screw of described central gear is many.
The radius of described central gear is 2 times of leading screw radius.
Feed screw nut with the leading screw engagement is installed on the leading screw of described exhaust unit.
The leading screw base that also includes the feed screw nut of rotatable lifting in the exhaust unit.
Advantage and good effect that the present invention has are
As above in the indoor machine of air-conditioner of the present invention of Gou Chenging, a plurality of leading screw lifting exhaust units is set respectively, therefore, the steadily of centre of gravity of exhaust unit reduces it and rocks degree, makes the lifting that exhaust unit can be stable.
