The rotor 11c of

fan

11a and 11b is contained in separately in the shell 11d, and above-mentioned shell 11d is for example made by plastic material.

As in the conventional electric motor, this electro-motor 9 comprises load-carrying members 12 and the connected driving shaft 13 of rotor (not shown in FIG.) that is used for support stator element (not shown in FIG.).

For drive described that to fan 11a and 11b, driving shaft 13 stretches out along rotary longitudinal line (X-X) from the two ends of electro-motor 9.

Electro-motor 9 can be installed in and be positioned at 10 li on support, and the effect of this support 10 is support electric motor 9 at work.

Specifically, such described in detail as follows in fan/convector 1, motor bracket 10 is connected to the groove 14 that is used to collect condensed water.

According to preferred embodiment, hot well 14 is made by the plated metal sheet of for example 1mm thickness.This prevents that bacterium, microorganism and mould from growing in the condensate draining borough chief phase.

Must be transferred to the drainage system of building by the exhaust system (not shown in FIG.) at the condensed water of 14 li collections of groove, this just can realize removing stopper 27 backs.

Stopper 27 and relative exhaust system are arranged on the right side or left side of groove 14, and effect is all good equally.

With reference to figure 2, it will be appreciated that specifically groove 14 is a rectangular shape, its pedestal 14a has hypotenuse 14b.

Should be noted that groove 14 also can adopt for example other shapes of square configuration, and also can adopt other locus of vertical position for example and without horizontal level, this shape and position are consistent with the outer shape and the position of fan/convector 1.

According to preferred embodiment, specifically referring to figs. 2 and 3, support 10 is that for example thickness is the form of the U-shaped bending metals plate structure of 2.5mm, and support 10 is provided with substrate 15 and pair of sidewalls 16 and 17.

Sidewall

16 and 17 has groove 18 and 19 separately, and described groove 18 and 19 is suitable for laying the

appropriate section

20 and 21 of motor 9, that is, described groove 18 and 19 can play electronic motor 9 bearings.

According to preferred embodiment, the described part 20 of electro-

motor

Support 10 and

fan

11a and 11b are connected to the outer surface of the pedestal 14a of groove 14,, are connected to not the surface as the condensed water collecting zone that is.

Therefore, groove 14 plays simultaneously and is used to collect the well of water and the effect that is used to support or keep the structure of a plurality of electromechanical assemblies, and in this embodiment, described a plurality of electromechanical assemblies are electro-motor 9 and

fan

11a and 11b.

Specifically, by the jockey 22 of for example screw, support 10 is connected to the pedestal 14a of groove 14.

Should be noted that these screws are the self-tapping screws that have three projectioies on the cross section in a specific embodiment of the present invention.

Advantageously, these self-tapping screws 22 are screwed onto in the smooth hole, promptly do not have in advance in the hole of screw thread, make that in the tapping operating process by plastic deformation, screw has formed the opposite threads with them.Therefore, near the screw thread that forms, the continuity of material fiber makes that the connection that produces is suitable for guaranteeing firm grip and optimally stops breaking away from.

Therefore, this method guarantees not have water to leak into the inside of fan/convector 1 from groove 14.

In fact, a part of 14c of the pedestal 14a of groove 14 becomes spill with the form of cup, and its end is as flange 26.

In case screw 22 is tightened, that is,, promptly in elastic limit, apply active force because screw 22 is applied to the pulling force on the concave portions of groove 14, make this concave portions shrink, cause flange 26 to be connected to the bar portion 29 of screw 22.

Therefore, the top 28 of flange 26 is on the higher horizontal plane than the pedestal 14a of groove 14, thereby prevents that condensed water from overflowing by the bearing of screw 22.

Use another advantage of this type of screw to be, can reduce the step of handling the metallic matrix that engages with self-tapping screw.Specifically, can avoid boring and to the hole tapping, so this can save production time and cost.

In addition, the advantage of this solution also has: it need not be used for the open washer of clamp operation between screw 22 and flange 26.

Advantageously, support 10 and groove 14 have complementary positioner 23, and this complementation positioner 23 can produce the form fit of support 10 with respect to groove 14 predetermined location.

In this embodiment, complementary positioner 23 is taked such form, a plurality of projections is promptly arranged on the pedestal 14a of groove 14 or swell 24, and this projection or protuberance are placed in the recess that forms in the substrate 15 of support 10 or cave in 25.

In other words, as shown in Figure 2, groove 14 has a plurality of projections 24, and these a plurality of projections 24 are adapted to be mounted within the corresponding hole 24 in the support 10.

The existence in these projections 24 and corresponding hole 25 makes it possible to obtain the accurate location of support 10 with respect to groove 14; That is, between groove 14 and support 10, produce form fit.

Because motor bearing 10 is the places that are used to admit electro-motor 9, motor is used for driving force being provided for

fan

11a and 11b by driving shaft 13, so present embodiment has advantageously been eliminated the error that may produce at assembling stage.

With reference to the specific embodiment of figure 2, the assembling that support 10 allows the geometric center C ' of the geometric center C of support 10 and groove 14 to overlap with respect to the location of groove 14.

This has very advantageously guaranteed to carry out not lacking between erecting stage symmetry at support 10 with respect to

fan

11a and 11b.

This solution highly significant because mechanicalness noise has been eliminated or has reduced at least.Have only and located support 10, just can obtain this benefit so that as far as possible accurately meet technical requirement on design.

Nature, in order to satisfy interim and specific requirement, those of ordinary skills can be with many improvement and change application in above-mentioned assembling, however all improvement and changing all are included in the protection scope of the present invention that is limited by appending claims.
