When starting the defrosting of air-conditioningWhen function, although blower fan quits work, wind still can blow to commutator face, takes away amount of heat, simultaneously owing to enteringAir port is relative with heat exchanger, and therefore wind also can blow to heat exchanger from air inlet, thereby has a strong impact on defrosting effect. Also do not have at presentThere is good mode to solve the problem of traditional air-conditioning frosting.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide one to be applicable to clammyAir-conditioning heating under environment and the good air-conditioner outdoor unit of windproof defrosting effect.
Air-conditioner outdoor unit described in the utility model, comprises casing, blower fan and the heat exchanger that carries out heat exchange with outdoor air,The top of the front panel of casing arranges suction opeing, and the bottom of its rear board or the bottom of side panel or while are in the backThe bottom of plate and side panel arranges passive air inlet; Blower fan and heat exchanger are positioned at the top of chassis cavity, the position of blower fan with take outAir port is corresponding, and the position of heat exchanger is higher than passive air inlet; Blower fan and suction opeing are positioned at a side of heat exchanger, passive air intakeMouth is positioned at the opposite side of heat exchanger.
In the utility model, the air inlet of off-premises station is passive air inlet (shutter can be installed at passive air inlet place),Therefore only under the prerequisite of blower fan work, wind could, from passive air inlet inlet flow to heat exchanger, be equivalent to heat exchanger by hiddenCover in casing, effectively protect by casing heat exchanger, thereby can play protection effect; Stop work at blower fanAfter work, extraneous wind can not enter into casing inside or blow to the surface of heat exchanger, is conducive to the defrosting of outdoor unit heat exchanger.
In the utility model, heat exchanger comprises the fin that some parallel longitudinals are arranged and is applied in the heat exchanger tube in fin. Preferably, on the windward side of heat exchanger, the outward flange of fin is 0～5mm with the distance that is positioned at outermost heat exchanger tube. Tradition is emptyFin outward flange in the heat exchanger of tune off-premises station is 6～9mm with the distance that is positioned at outermost heat exchanger tube, at clammy environmentUnder, because outside air temperature is low, therefore, the outward flange of fin is far away apart from heat exchanger tube, and the more difficult thawing of frost, does not more allowEasily defrosting. Therefore in the utility model, adopt the method raising that reduces distance between fin outward flange and outermost heat exchanger tubeFrost effect.
In tradition air-conditioner outdoor unit, the spacing of fin of heat exchanger be equidistant, is generally 2.2mm, under clammy environment (as meThe winter in the state north) while heating with air-conditioning, easily frosting on fin, and the easy frosting in the outside of fin, inner sideBe difficult for frosting, because spacing of fin is less, air-conditioning continue to heat in process, often there will be fin large area by frost layerThe phenomenon of shutoff and be difficult for defrost, also can freeze sometimes, affects heat exchanger heat exchange, finally reduces the heating efficiency of air-conditioning. ForAddress this problem, the utility model adopts following preferred version: in described heat exchanger, fin ecto-entad is at least establishedPut two groups; Ecto-entad (from the windward side of heat exchanger to its lee face), the spacing of fin of respectively organizing fin reduces gradually; PositionSpacing of fin in outermost one group of fin is 2.4mm～4.0mm, considers other factors such as production cost, is positioned atThe spacing of fin of one group of fin of side can not be too small, the preferred 1.4mm～2.2mm of the utility model. Like this, on the one hand, outermostThe spacing of fin of side fin is relatively large, though frosting, can be easily by the large gap shutoff between fin yet, on the other hand,Part outside air frosting in the time flowing through the fin of intermediate layer or internal layer, has effectively avoided completely in fin outer frostingProblem, makes frosting even, is conducive to evenly defrost in time simultaneously.
When tradition air-conditioning heats in clammy environment, because the water after defrost can not be discharged in time, therefore often can cause water knotBecome ice and accumulate in the situation of heat exchanger the latter half, equally also can affect heat exchanger heat exchange, finally reduce the effect that heats of air-conditioningRate. The utility model has adopted heat exchanger has been divided into the technical scheme that upper and lower many group heat exchange units carry out separately draining for this reason,Concrete preferably following two schemes:

Described heat exchanger at least comprises two groups of heat exchange units, from top to bottom longitudinally or inwardly oblique arranging of each heat exchange unit;Between upper and lower two groups of adjacent heat exchange units, separate by space bar, space bar is oblique having a down dip from inside to outside. At this programmeIn, each heat exchange unit can not stagger, and also can partly stagger, and also can stagger completely. Stagnant in order to prevent the water after defrostStay, in the inner side of space bar, water fender is set. For the ease of the water after defrost is drawn fast in time, make draining more thoroughThe end,, at the arranged outside Diversion Plate of space bar, the angle of inclination of Diversion Plate is not less than the angle of inclination of space bar. Consider peaceTotal factor, forms safety guard by the end downward bending of Diversion Plate. Between above-mentioned upper water fender and space bar, intervalBetween plate and Diversion Plate and between Diversion Plate and safety guard, can adopt arc transition, to reduce the resistance to water, favourableDischarge in time in water.
Scheme two:
Described heat exchanger at least comprises two groups of heat exchange units, longitudinally or inwardly oblique arranging of each heat exchange unit from top to bottom,Between each group heat exchange unit, stagger completely. For the water being changed into by frost in defrost process being discharged in time, belowThe bottom of heat exchange unit arranges water collection sheet, and water collection sheet is oblique having a down dip from inside to outside, makes the water of each heat exchange unit drop at any time collectionOn water plate, and from off-premises station, discharge in time by drainpipe or other drainage arrangements.
Except above-mentioned points, due to the limitation of conventional outdoor unit height, the air inlet of air-conditioner outdoor unit and the distance of air outlet conventionallyVery near, easily like this cause air short circuit, the very large wind of air of discharging from air outlet can enter chamber by air inlet againIn outer machine, make operation of air conditioner unstable, therefore the utility model can also adopt following preferred version, makes outdoor set cabinetHighly be greater than its length, thereby greatly increase the distance between passive air inlet and suction opeing, guarantee that operation of air conditioner is stable, andThere is energy-saving effect.
