Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
See Fig. 1, the invention provides a kind of indoor apparatus of air conditioner 10, comprise volute of blower 20, median septum 30 and evaporimeter 50, described volute of blower 20 is arranged on the side of described median septum 30, spiral case air outlet 21 is arranged on described median septum 30, and described evaporimeter 50 is arranged on described median septum 30 opposite side, relative with described spiral case air outlet 21, described air outlet 21 is also provided with air ducting, guides uniform stream to blow to described evaporimeter 50.The present invention, by arranging air ducting on spiral case air outlet, guides uniform stream to blow to described evaporimeter, makes air-supply more even, improves evaporator heat exchange effect, avoids the unit condensation because heat exchange inequality causes and wind pushing temperature non-uniform phenomenon.
Wherein, described air ducting is multiple horizontally disposed wind deflectors 40, and multiple wind deflector 40 is horizontally set between spiral case air outlet 21 top edge and lower limb.Form gas channel between wind deflector 40, guide air flow direction evaporimeter.
Continue see Fig. 1, air outlet 21 top edge is horizontally disposed with, the lower limb of air outlet 21 and wind deflector 40 are away from all downward-sloping setting in side of spiral case 20, such setting, the flow level blowout on air outlet 21 top, the downward-sloping blowout of air-flow of middle and lower part, spreads under using wind direction, add the front face area of evaporimeter 50 bottom, make evaporimeter 50 heat exchange more even.
Find through research, the angle of inclination of the lower limb of wind deflector and air outlet 21 is the uniform key factors of impact air-supply, in order to more even to the air-supply of evaporimeter 50, from described air outlet top edge to described air outlet lower limb direction, each described wind deflector 40 increases gradually with the angle of horizontal direction.Namely the angle near the 1st wind deflector of air outlet top edge and horizontal direction is minimum, and straight down the 2nd, the angle of the 3 to the n-th wind deflector and horizontal direction increases successively, and the angle of air port lower limb and horizontal direction is maximum.
See Fig. 2, as another kind of embodiment, the median septum 30 of indoor apparatus of air conditioner 10 is provided with pressure compensation opening 31.Described spiral case air outlet 21 can be multiple, and the median septum 30 described in each between spiral case air outlet 21 is provided with pressure compensation opening.By arranging pressure compensation opening, the equilibrium pressure field of force, reduces the air-flow flow-disturbing caused owing to there is dead corner between median septum pressure at both sides imbalance and air port, thus reduces pneumatic noise.
For reducing air-flow flow-disturbing further, the median septum 30 between air outlet 21 and unit sidewall is also provided with pressure compensation opening 31, that is, the both sides of each air outlet 21 are provided with pressure compensation opening 31.Wherein, the pressure compensation opening 31 of each air outlet 21 both sides is with the formal distribution of pressure compensation opening group, and described pressure compensation opening group is vertically arranged by described multiple pressure compensation opening 31 and formed.Can arrange row between each air outlet 21 and also can arrange multiple row pressure compensation opening group, pressure compensation opening group is preferably arranged in the middle part of the region between air outlet 21.When being provided with multiple row pressure compensation opening group, that is, by multiple pressure balance hole horizontal, vertical evenly distributed formed time, the spacing of pressure compensation opening vertical direction is less than the spacing of horizontal direction.
While ensureing air quantity, reduce air-flow flow-disturbing, the diameter of pressure compensation opening is not more than 7mm.In this size range, air quantity is not affected, and noise reduction is better.
Be existing indoor apparatus of air conditioner air flow method cross sectional representation see Fig. 4 and Fig. 6, Fig. 4; Fig. 6 is existing indoor apparatus of air conditioner air flow method top view.As can be seen from Figure 4, in existing air-conditioning there is backflow phenomenon in evaporimeter lower stream of airflow, obviously less through evaporimeter bottom air quantity, and evaporimeter bottom heat transfer effect is affected, and causes the upper and lower heat exchange of evaporimeter uneven.As can be seen from Figure 6, between air port near the position of median septum and between air port and side plate near the position of median septum, because the reason of pressure field and air quantity difference causes flow-disturbing phenomenon, gas-flow resistance increases, and causes pneumatic noise.
Be the air flow method of indoor apparatus of air conditioner shown in Fig. 1 cross sectional representation see Fig. 3 and Fig. 5, Fig. 3; Fig. 5 is the air flow method of indoor apparatus of air conditioner shown in Fig. 1 top view.As can be seen from Figure 3, the upper and lower air quantity of evaporimeter of air-conditioner of the present invention is all relatively more even, and as can be seen from Figure 5, the flow-disturbing phenomenon near air-conditioner median septum of the present invention disappears substantially, airflow smooth, and pneumatic noise reduces.
The present invention by arranging air ducting on spiral case air outlet, uniform stream is guided to blow to described evaporimeter, by arranging pressure compensation opening on median septum, decrease air-flow flow-disturbing, make air-supply more even, improve evaporator heat exchange effect, reduce noise, avoid the unit condensation because heat exchange inequality causes and wind pushing temperature non-uniform phenomenon.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
