Abstract
The utility model discloses an axial-flow fan for a window type air conditioner. The axial-flow fan for a window type air conditioner comprises a bent leaf type impeller and a water beating ring fixedly connected to a rib plate of an outer edge. Water flinging grooves are evenly distributed on the circular ring plate surface of the water beating ring. The number of the water flinging grooves evenly distributed on the water beating ring is 3-100. The radial cross section of the inner surface of the water flinging groove forms an inverted L shape or a U shape or a parabola shape or a W shape. Most of condensation water can be evenly emitted on a condenser when the fan is operated. The utility model has the advantages that the condensing effect of the condenser can be reinforced; the refrigeration effect of the window type air conditioner can be increased; the efficiency ratio of the air conditioner is enhanced.
Description
The utility model relates to the improvement of window air conditioner, specifically is a kind of aerofoil fan of window air conditioner, and it belongs to the air-conditioner technical field.
The aerofoil fan of window air conditioner plays an important role to the condensation radiating effect of strengthening condenser in the prior art.Aerofoil fan is to be connected with hydrosphere by the gusset on the impeller outer edge.Original hydrosphere is to connect admittedly on impeller outer edge with plate shaped Circular Plate face.This hydrosphere is because its plate shaped Circular Plate face is difficult for taking up equably more water curtain, therefore its efficient of fetching water is low, water smoke is difficult for evenly being diffused into condenser surface, make that the high-temperature medium cooldown rate in the condenser is lower, hinder the raising of condenser cooling effect, thereby had influence on the raising of the operational energy efficiency ratio of whole refrigeration system.
The purpose of this utility model is to excavate the refrigeration of window air conditioner (heat) potentiality, strengthen the radiating effect of condenser, improve the Energy Efficiency Ratio of air-conditioner, improve the aerofoil fan of original window air conditioner, strengthen condensed water distributing to condenser, improve condensation effect, under same power consumption condition, obtain the air-conditioning effect of higher refrigeration (heat).
Task of the present utility model is finished by following technical scheme, has developed a kind of aerofoil fan of window air conditioner, and it comprises: curved blade type impeller and outer rim gusset thereof connect solid hydrosphere, on the Circular Plate face of hydrosphere uniform water splash groove are set.
The described water splash groove of the aerofoil fan of this window air conditioner, its number that is distributed on the Circular Plate face of hydrosphere is 3-100 piece.
The described water splash groove of the aerofoil fan of this window air conditioner, the radial section of its groove cave inner surface is inverted "L" shaped, or is " U " shape, or be parabola shaped, or is " W " shape.
The described curved blade type impeller of the aerofoil fan of this window air conditioner, its bent blades number is the 4-6 sheet.
Good effect of the present utility model is: owing to be provided with uniform water splash groove on original hydrosphere, make and more condensed water is arranged by the homogeneous band pocket, again because the fan centrifugal action, just can get rid of ejaculation equably with rolling water, just in time can get rid of on the radiating fin that is mapped to condenser, the condensed water of a large amount of low temperature just can carry out heat exchange with the high temperature refrigerant in the condenser, and refrigerant is cooled down rapidly, has improved the radiating effect of condenser.Owing to designed the water splash groove of different shape, the great efforts that make condensed water get rid of to penetrate have been strengthened condensed water to the distributing of condenser, and make under same power consumption condition, obtain higher air conditioner refrigerating (heat) effect.
Embodiment of the present utility model is described below in conjunction with the accompanying drawings:
Fig. 1 is impeller and " L " shape hydrosphere structural representation thereof of aerofoil fan;
Fig. 2 is " L " shape water splash groove radial section cutaway view (the A-A cutaway view Amplified image of Fig. 1);
Fig. 3 is impeller and " U " shape hydrosphere structural representation thereof of aerofoil fan;
Fig. 4 is " U " shape water splash groove radial section cutaway view (the A-A cutaway view Amplified image of Fig. 3);
Fig. 5 is " W " shape water splash groove radial section cutaway view;
The aerofoil fan of the window air conditioner of making referring to Fig. 1-5, it comprises: five curved blade type impellers 1 connect intrinsic hydrosphere 3 on this impeller 1 outer rim gusset 2.Be distributed on this and enclose 36 pieces water splash groove 5 on the 3 circumference plate faces being provided with on the Circular Plate face of hydrosphere 3.
The water splash groove 5 that the hydrosphere 3 of this aerofoil fan is designed, the radial section of its groove cave inner surface 4 is inverted "L" shaped as shown in Figure 2.The inner surface 4 of this water splash groove 5 can be designed to the water splash groove 5 that radial section is " U " shape, as shown in Figure 4; Also can be designed to radial section and be the water splash groove 5 of " W " circular arc, as shown in Figure 5.
Claims (4)
1, a kind of aerofoil fan of window air conditioner, it comprises: curved blade type impeller and outer rim gusset thereof connect solid hydrosphere, it is characterized in that: on the Circular Plate face of fetching water round uniform water splash groove is set.
2, according to the aerofoil fan of the described window air conditioner of claim 1, it is characterized in that: described water splash groove, its number that is distributed on the Circular Plate face of hydrosphere is 3-100 piece.
