Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
In figure, the direction of arrow indicates air-flow direction, and the direction entered with air is front.
See shown in Fig. 1 to Fig. 4, according to embodiments of the invention, centrifugal blower comprises motor 1, centrifugation blade 2 and backward spiral case 3, and centrifugation blade 2 drives with motor 1 and is connected, and rotates under the driving of motor 1; Backward spiral case 3 is located at outside centrifugation blade 2, and forms the air-guiding aisle 4 extended from all side direction rears of centrifugation blade 2.
Centrifugal blower of the present invention, have employed new worm frame, after making the air draught of centrifugal blower front, from all side direction rear air-out of centrifugation blade 2, change the air exhausting structure of traditional centrifugal blower, make the structure of centrifugal blower to realize variation, and the volume of spiral case can be reduced, realize the miniaturization of centrifugal blower.
After air-flow sucks from the front of centrifugation blade 2, throw away from the circumference of centrifugation blade 2, the air-guiding aisle 4 then along backward spiral case 3 flows to the rear of centrifugal blower, makes exhaust outlet form large hydrodynamic air, realizes the powerful air-out of exhaust outlet.Air-guiding aisle 4 is herein annular wind guide chamber, thus forms annular air-out at the outlet air end of centrifugal blower.
Preferably, air-guiding aisle 4 tilts laterally along the direction away from centrifugation blade 2, more can match with the air inlet/outlet feature of centrifugation blade 2, makes centrifugal blower have more excellent air inlet/outlet performance.
Air-guiding aisle 4 has arc wind-guiding face 6, and air-flow is along arc wind-guiding face 6 air-out of air-guiding aisle 4, and make air current flow more smooth and easy, the resistance be subject to is less, and air inlet/outlet efficiency is higher.
Centrifugal blower also comprises guide plate 5, and guide plate 5 is arranged on the air inlet of centrifugation blade 2, can form leading role, improve the air intake efficiency of centrifugal blower to the air-flow entered in centrifugation blade 2.
In conjunction with see shown in Fig. 5 to Fig. 7, according to embodiments of the invention, air conditioner comprises centrifugal blower 11, and this centrifugal blower 11 is above-mentioned centrifugal blower.
In conjunction with see shown in Fig. 5 and Fig. 6, for the first embodiment of air conditioner according to the present invention, in the present embodiment, air conditioner also comprises top cover 7, air inlet/outlet main casing 8, heat exchanger 9 and chassis 10, top cover 7, air inlet/outlet main casing 8 and chassis 10 surround cavity, and centrifugal blower 11 is arranged in cavity, and heat exchanger 9 is arranged between the intake grill of centrifugal blower 11 and air inlet/outlet main casing 8, the exhaust outlet of air inlet/outlet main casing 8 is corresponding with the intake grill of air inlet/outlet main casing 8 to be arranged, thus the air conditioner that formation one is complete.
Traditional spiral case inlet pressure broken through by this air conditioner, makes centrifugal blower 11 be with kinetic pressure to change and forms air pressure difference, carry out heat exchange, blow out afterwards, and enter centrifugal blower 11 from heat exchanger 9 after air enters from the intake grill of air inlet/outlet main casing 8 by heat exchanger 9.Enter the centrifugation blade 2 of centrifugal blower 11 at air after, the oblique rear of past centrifugation blade 2 is to air-out, tiltedly lead to radian at rear along backward spiral case 3, after backward spiral case 3, air-out enters air inlet/outlet main casing 8 wind outlet cavity, and then from the exhaust outlet air-out of air inlet/outlet main casing 8, form air-conditioning overall operation.
In conjunction with shown in Figure 7, for the second embodiment of air conditioner of the present invention, in the present embodiment, structure is substantially identical with the first embodiment with principle, and difference is, in the present embodiment, centrifugal blower 11 is multiple, multiple centrifugal blower 11 is placed side by side, thus can improve the air inlet/outlet ability of centrifugal blower 11, improves the service behaviour of air conditioner.
Preferably, multiple centrifugal blower 11 is communicated with between the intake grill at the rear adjacent boundary place to spiral case 3, is communicated with, thus can strengthens air circulation between exhaust outlet, improves air flow uniformity and the flow efficiency of centrifugal blower 11 entirety further.
In the present embodiment, air inlet/outlet main casing 8 can have upper exhaust outlet, to realize the upper air-out of air conditioner, also can have lower exhaust outlet, to realize the lower air-out of air conditioner, can also have upper and lower exhaust outlet simultaneously, thus realizes the air-out simultaneously up and down of air conditioner.Preferably, the air outlet position of air inlet/outlet main casing 8 can arrange a movable wind outlet panel, till the motion by adjustment panel, thus realizes the upper air-out of air conditioner, lower air-out or air-out simultaneously up and down, realize the diversity of air conditioner air-out, strengthen the travelling comfort of air conditioner.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
