Above-mentioned evaporation roughly is rectangular shape with heat exchanger 131, can block the major part of the place ahead vertical plane of indoor heat exchange department 130, so it can be between above-mentioned indoor air inlet 113 and exhaust outlet 114.In addition, that above-mentioned indoor fan 132 adopts is a kind of of centrifugal fan---turbine fan (turbo fan), thereby it can be with air from the front by the indoor air inlet 113 on the front vertical plane of cabinet 110, along axial suction, and then with air along circumferencial direction row to indoor exhaust outlet 114.
Evaporation is to be provided with the indoor guiding parts 133 that room air can be guided to the suction side of indoor fan 132 between the indoor fan 132 with heat exchanger 131 and turbine fan.The top of indoor fan 132 is provided with can be with the indoor air baffle 134 of room air to 114 guiding of indoor exhaust outlet.
For indoor side heat exchanger 131 and indoor fan 132 being separated, indoor guiding parts 133 preferably roughly is rectangle, and its centre has formed roughly identical with the suction side of the above-mentioned indoor fan 132 air vent 133a of diameter.And in order to enlarge the interval t1 between it and the indoor side heat exchanger 131, its dual-side is along then having formed passage expanding surface 133b on the part, the past more end of this passage expanding surface 133b recedes towards the direction of indoor fan more, thereby it can enlarge air intake passage.
, consider the shape of the blade end of indoor fan 132 here, above-mentioned passage expanding surface 133b is preferably in not in the scope that the end with indoor fan 132 clashes, and recedes as much as possible.
In addition, be provided with dividing plate 115 between outside heat exchange department 120 and the indoor heat exchange department 130, this dividing plate 115 can be separated into outside and indoor to the inside of cabinet 110.Dividing plate 115 is provided with fan electromotor 140, and the both sides rotating shaft of fan electromotor 140 is connected with indoor fan 132 with above-mentioned outdoor fan 123 respectively, thereby can provide revolving force to them.
The effect of the indoor air inlet structure of aforesaid window air conditioner of the present invention is described below.
If air-conditioning has been connected power supply, compressor 121 will drive so, circulates thereby cold-producing medium is used in the heat exchanger 131 with heat exchanger 122 and evaporation in condensation.Meanwhile, fan electromotor 140 also can drive, thereby outdoor air and room air can be drawn into the outside and the indoor of cabinet 110 respectively.The outdoor air that is inhaled into can be that condensation realizes heat exchange with heat exchanger 122 with outdoor heat exchanger, and the room air that is inhaled into can promptly evaporate with heat exchanger 131 with indoor side heat exchanger realizes heat exchange.By heat exchange the state of the cold-producing medium in each heat exchanger 122,131 is changed, and outdoor air can become hot-air row to outdoor in this process, room air can become cold air row to indoor.
Again said process is illustrated in further detail below.
As shown in Figure 5, because the inside of outside is provided with the axial flow fan as outdoor fan 123, thereby along with the driving of outdoor fan 123, outdoor air can be inhaled into the rear of outdoor fan 123 from the side by the outside air inlet 111 on two sides of cabinet 110, can arrange again to outdoor by outside exhaust outlet 112 again then.The words that wherein above-mentioned outside exhaust outlet 112 is as the criterion with the indoor are to be positioned at the rear, in other words are the place aheads that is positioned at the outside of cabinet.In this process, outdoor air is by being that condensation contacts with heat exchanger 122 with outdoor heat exchanger, can be from condensation with draw heat the gaseous refrigerant of heat exchanger 122, thus make gaseous refrigerant change into the liquid refrigerant of high temperature, and air then becomes hot-air and discharges.
On the other hand, owing to be provided with indoor fan 132 in the indoor, and what this indoor fan adopted is a kind of of centrifugal fan---turbine fan, therefore room air can be crossed indoor air inlet 113 inflows that form by the past square tube on the latter half of cabinet 110 fronts, can arrange again to indoor by the indoor exhaust outlet 114 that forms on the first half of cabinet 110 fronts again then.In this process, room air contacts by promptly evaporating with heat exchanger 132 with indoor side heat exchanger, heat can be discharged to the liquid refrigerant in the above-mentioned evaporation usefulness heat exchanger 132, thereby make liquid refrigerant change into gaseous refrigerant, air then becomes cold air and arranges again to indoor.
Here, as shown in Figure 6, room air not only can flow to indoor fan 132 with the core of heat exchanger 131 by the evaporation relative with the suction side of indoor fan 132, meanwhile, owing to formed passage expanding surface 133b on the indoor guiding parts 133, thereby room air can also be by evaporation with flowing to indoor fan 132 near the edge part of heat exchanger 132.In addition, owing to formed passage expanding surface 133b on the indoor guiding parts 133, make evaporation big more the closer to the part at edge, thereby the air intake zone can increase thereupon with the interval between heat exchanger 131 and the indoor guiding parts 133.The impedance of air intake passage is reduced, thereby the soakage of room air is increased, pneumatic noise then reduces.
In addition, along with the increase of the soakage of room air, the air output of air-conditioning also can correspondingly increase, thereby can promote the performance of air-conditioning.Moreover, evaporation not only comprises the length L of middle body with the heat-exchange surface scope of heat exchanger 131, but also has expanded to the length L 1+L1 of edge part always, thereby the performance of heat exchanger is significantly improved.
Have a look another example of the air inlet structure of window air conditioner of the present invention below again.
In above-mentioned example, the edge part of indoor guiding parts 133 is that past more end recedes towards the direction of indoor fan more, thereby formed passage expanding surface 133b, the space of this minimum coming to a point gradually (taper) can be effectively utilized in the suction side of indoor fan 132 then.This example situation as shown in Figure 7 then is that the centre of indoor guiding parts 233 recedes towards the indoor fan direction, thereby form passage expanding surface 233b, thereby this example not only can reduce the impedance of air intake passage, can also expand to heat exchange area in the scope of whole evaporation with the longitudinal length L2 of heat exchanger 131 simultaneously.233a among the figure is a ventilating opening.
Here, can be placed on indoor fan 132 on the origin-location, then the passage expanding surface 233b of indoor guiding parts 233 be made the structure of slight inclination; Also can move indoor fan 132 a little backward, simultaneously the passage expanding surface 233b of indoor guiding parts 233 be made the structure of the bigger angle of inclination.
The former can reduce the channel impedance for room air, thereby improve noise, air quantity and heat transfer area to a certain extent in the length between the indoor and outdoor that keeps air-conditioning slightly.Though how many latter makes the length between the indoor and outdoor of air-conditioning increase to some extent, it can reduce the channel impedance for room air largely, thereby improves noise, air quantity and heat transfer area significantly.
