Abstract
The utility model provides a fan snail shell, in particular to a foam type air-conditioner centrifugal fan snail shell, which has a large cavity volume and satisfactory strength and may give the fan high efficiency. The snail shell comprises an air outlet, a cavity and a snail shell, wherein in the thinner part of the snail shell is provided additionally with a strengthening element for increasing the strength of the snail shell. The utility model, without changing the general length or width of the snail shell, increases the fan efficiency and improves the snail strength by enlarging the internal cavity and adding a strengthening element at the thinner part.
Description
[technical field]
The utility model relates to the volute of blower in the air conditioner, especially a kind of foam type spiral case of air conditioner centrifugal blower.
[background technique]
At present, the volute of blower of most of cabinet air conditioners is according to air conditioner Inner Dimension space requirement, and to the requirement of spiral case intensity, generally adopt the little foam type spiral case of whole big, the inner die cavity of wall thickness of spiral case, this just causes the whole air-out efficient of blower fan not high, the shortcoming of deficiency in draught.If overcome the shortcoming of deficiency in draught, and the one, adopt powerful blower fan, this just not only will increase energy consumption, has also improved the complete machine noise; Or the overall dimensions of increase volute of blower, this will need the overall dimensions of corresponding adjustment air conditioner, and manufacturing process is brought inconvenience.Therefore, press for a kind of the change under the overall dimensions prerequisite of air conditioner, can strengthen the spiral case die cavity volume of blower fan, improve the efficient of blower fan, can satisfy the volute of blower of the requirement of strength of spiral case again.
[model utility content]
The utility model overcomes the deficiencies in the prior art, provides the inner die cavity volume of a kind of volute of blower big, and the fan efficiency height satisfies the foam type spiral case of the air conditioner centrifugal blower of spiral case requirement of strength.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of foam type spiral case of air conditioner centrifugal blower comprises exhaust outlet, die cavity and spiral case, it is characterized in that the wall thickness thin location of spiral case is provided with the reinforcer that strengthens spiral case intensity.
The foam type spiral case of aforesaid air conditioner centrifugal blower is characterized in that described reinforcer under spiral case length overall and beam overall constant dimension situation, is arranged on to increase the shell wall outside that inner cavity dimension makes the attenuation of spiral case wall thickness.
The foam type spiral case of aforesaid air conditioner centrifugal blower is characterized in that described reinforcer is the sheet metal part that is embedded in spiral case left and right side wall thickness thinnest part.
The foam type spiral case of aforesaid air conditioner centrifugal blower is characterized in that at least being provided with the portion of inlaying in the and arranged on left and right sides of described reinforcer.
The foam type spiral case of aforesaid air conditioner centrifugal blower is characterized in that the described portion of inlaying is a flange that is connected with sheet metal part.
The foam type spiral case of aforesaid air conditioner centrifugal blower is characterized in that the thickness of described sheet metal part is at least 0.6mm.
The foam type spiral case of aforesaid air conditioner centrifugal blower, the thinnest part that it is characterized in that described spiral case is not more than and is 5mm.
Compared with prior art, the utility model has the advantages that:
The utility model is in manufacturing and designing process, do not changing under the overall dimensions situation of air conditioner inside, by strengthening the size of foam type spiral case inside, increase the die cavity volume, after making the wall thickness attenuation of the left and right sides of spiral case, the sheet metal part that wall thickness is 0.6mm is inlayed in employing in the foam type spiral case of its both sides, to increase the intensity of spiral case; After adopting this structure, do not changing under spiral case length overall and the beam overall size, increasing spiral case die cavity volume, improving the efficient of blower fan, satisfying the requirement of strength of spiral case simultaneously.

Fig. 2 is a three-dimensional explosive view of the present utility model;
Fig. 3 is the schematic representation after the utility model is cut spiral case top open;
Fig. 4 is the partial enlarged drawing that the utility model is inlayed the sheet metal part place.
[concrete real-time mode]
A kind of foam type spiral case of air conditioner centrifugal blower as depicted in figs. 1 and 2, comprises exhaust outlet 1, die cavity 2 and spiral case 3, is provided with the reinforcer 4 of enhancing spiral case 3 intensity at the wall thickness thin location of spiral case; By under the situation of spiral case 3 length overalls and beam overall size constancy, increase the size of the inner die cavity 2 of foam type spiral case, set up reinforcer 4 in spiral case 3 wall thickness attenuation place, reach the efficient that has both improved blower fan, satisfy the requirement of strength of spiral case 3 simultaneously.
As shown in Figure 3 and Figure 4, described reinforcer 4 is for being embedded in the sheet metal part 40 of spiral case left and right side wall thickness thinnest part, while is provided with the portion of inlaying 41 in the and arranged on left and right sides of reinforcer 4 at least, the described portion 41 of inlaying is a flange that is connected with sheet metal part 40, make thickness be the sheet metal part 40 of 0.6mm can to inlay advance thinnest part securely be in the foam type spiral case 3 of 1mm, thereby guarantee the intensity of spiral case 3.
The utility model during fabrication, at first two sheet metal parts 40 are placed in the mold slots of processing spiral case 3, after 3 moulding of foam type spiral case, two sheet metal part 40 smooth being embedded on the spiral case 3, two sheet metal parts of inlaying 40 are in company with 3 one depanning of foam type spiral case then, it is firmly reliable both can to have guaranteed that sheet metal part and foam type spiral case were inlayed, and can make the outer molded lines slyness of spiral case smooth again, makes things convenient for the assembling and the installation of spiral case.
