Embodiment
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 5 and Figure 6, according to indoor apparatus of air conditioner of the present invention, comprising: drain pan 42, front snail tongue 43, through-flow fan blade 41, through-flow fan blade 41 is equipped with on drain pan 42, forms exhaust outlet 12 between front snail tongue 43 and drain pan 42; Front snail tongue 43 comprises snail tongue body 431 and is equipped with snail tongue cover 432, snail tongue body 431 and drain pan 42 integrated injection molding on snail tongue body 431.Indoor apparatus of air conditioner of the present invention, with the snail tongue body 431 of drain pan 42 integrated injection molding depanning and the snail tongue cover 432 on snail tongue body 431 can be equipped with by being divided into by front snail tongue, due to snail tongue body 431 and drain pan 42 integrated injection molding, intensity is higher, can effectively prevent snail tongue from overlapping distortion, thus prevent front snail tongue to be out of shape, make its end even to the distance to through-flow fan blade 41, thus eliminate the uneven phenomenon of air-out.
As shown in Figure 7, snail tongue body 431 comprises the first flanging 431a of the inlet side near through-flow fan blade 41, with the second flanging 431b of the air side near through-flow fan blade 41, first flanging 431a and the second flanging 431b is in the shape of the letter V, and the drift angle of V-shaped is towards through-flow fan blade 41, adjusting accordingly according to depanning angle of vertex angle theta.The shape of certain snail tongue body 431 also can be designed as the shape that other are convenient to depanning and fixing snail tongue cover 432.
Preferably, snail tongue cover 432 is conveniently installed, adopts the mode of clamping to be fixed on snail tongue body 431 by snail tongue cover 432.As shown in Figure 7 and Figure 8, snail tongue cover 432 is provided with the hook-shaped buckle 432a of the first flanging 431a lower end being hooked on snail tongue body 431; Second flanging 431b of snail tongue body 431 is provided with recess a and is positioned at the projection a1 of recess a, snail tongue cover 432 arranges the catching groove 432b coordinated with projection a1.When installation snail tongue overlaps 432, first hook-shaped buckle 432a is hooked on the first flanging 431a lower end, has then used and catching groove 432b is buckled on projection a1, thus snail tongue cover 432 is fixed on snail tongue body 431.
Preferably, recess a is arranged on the middle part of the second flanging 431b, both facilitated, under the prerequisite of the requirement meeting depanning, projection a1 had been set on the second flanging 431b, and made again the projection a1 of setting conveniently coordinate with the catching groove 432b that snail tongue overlaps on 432, and snail tongue cover 432 had been installed more stable.
As shown in Figure 7 and Figure 8, snail tongue cover 432 is in bent plate shape, and comprise and connecting successively and the first plate, the second plate and the 3rd plate each other in kink shape, hook-shaped buckle 432a is arranged on the free end of the first plate, and catching groove 432b is arranged on the 3rd plate.Conveniently water receiving disc 30 is installed, also between the space of the bent plate shape of the first plate, the second plate and the 3rd plate composition, packing material 433 can be set, as foam etc.
As shown in Figure 7, the angle of the drift angle of the V-shaped of snail tongue body 431 is θ, the angle that snail tongue overlaps between 432 outermost both sides (i.e. the first limit and the 3rd limit) is α, wherein, α < θ, make the snail tongue after installation overlap 432 pairs of snail tongue bodies 431 and have certain clamping force, thus make fixing more reliable.Horizontal wind guiding blade is conveniently installed, can the buckle 432d installing horizontal wind guiding blade be set on the 3rd plate.
Preferably, in order to make snail tongue cover 432 fixing more stable, be difficult to be fixed on snail tongue body 431 after preventing snail tongue from overlapping 432 appearance distortion, as shown in Figure 7 and Figure 8, interior button 432c is also provided with inside snail tongue cover 432, interior button 432c is arranged on the second plate, and interior button 432c coordinates with the end of the drift angle of the formation V-shaped of the second flanging 431b of snail tongue body 431.Thus snail tongue cover 432 is fixed by hook-shaped buckle 432a, catching groove 432b, interior button 432c tri-groups of snap-fit engagement with snail tongue body 431, thus increase fastening degree.
Usual moulding all can have a certain amount of distortion after cooling completely, and in order to the drift angle preventing snail tongue body 431 to be out of shape rear V-shaped diminishes, and the first flanging bends.After preventing distortion and machining error, cause snail tongue to overlap and 432 cannot to buckle, as shown in Figure 7, certain prepsetting gap d is set between the fitting surface and the second flanging 431b of interior button 432c, be out of shape and the impact of machining deviation to eliminate snail tongue body 431.In the type of different model, the scope of prepsetting gap d is for being generally 0 to 1.5mm, and preferably scope is 0.3mm to 1mm, effectively can eliminate distortion and machining error, prevent from not installing, be unlikely to Tai Song again simultaneously and do not reach stable clamping level of installing.
As shown in Figure 7, in order to improve the reliability that interior button 432c coordinates with the second flanging, it is highly h that interior button 432c has along the bearing of trend of the second flanging 431b, h is larger, fixing more reliable after installing, but excessive easily the causing when installation of h is difficult to coordinate, and affects to installation, usually, 0.5mm≤h≤4mm.Preferably scope is 1 to 3mm, reliably can fix and is unlikely to again too large and causes installation trouble.
Front snail tongue entirety extracts in prior art by we, be arranged on again after molding and forming on drain pan and with the snail tongue body of drain pan integrated injection molding depanning and the snail tongue cover on snail tongue body can be equipped with of the present invention being divided into by front snail tongue, the product that these two kinds of modes are produced has carried out contrast test, because snail tongue amount of deformation before traditional approach is gone up middle unfixing greatly, before snail tongue very uneven to the distance of through-flow fan blade, cause exhaust outlet wind speed uneven, noise data is also larger.
The test data of the air conditioner indoor machine being 3.5KW with a specified refrigerating capacity under the most high-grade wind speed is as shown in following table one, and main test condition comprises: fan blade diameter 98mm, snail tongue room 6mm, air port length 600mm.Noise test condition is as follows: semi-anechoic room, immediately below 1.4 meters, A weighted.
The laboratory data of table one prior art and contrast test of the present invention
| Front snail tongue type | Noise (decibel) | Exhaust outlet wind speed is poor |
| Prior art | 42.4 | Maximum wind speed difference 2.8m/s |
| The present invention | 41.8 | Maximum wind speed difference 0.7m/s |
As can be seen from the laboratory data of table one, adopt front snail tongue of the present invention to have and effectively reduce noise, particularly the stable of wind speed is significantly improved.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to indoor apparatus of air conditioner of the present invention, with the snail tongue body of drain pan integrated injection molding depanning and the snail tongue cover on snail tongue body can be equipped with by being divided into by front snail tongue, due to snail tongue body and drain pan integrated injection molding, intensity is higher, can effectively prevent snail tongue from overlapping distortion, thus prevent front snail tongue to be out of shape, make its end even to the distance to through-flow fan blade, thus eliminate the uneven phenomenon of air-out.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
