Summary of the invention
Namely main purpose of the present invention is providing a kind of compressor reducing noise and oil recycle ratio.
Electric element in the present invention in compressor is provided with stator and rotor, and this stator has circular iron core, and plural number is with the stator coil of concentrated winding method, is formed and runs through upper and lower gap between adjacent stators coil; Wherein, a lid is provided with above this stator, this lid is provided with covering, this covering is formed with top along each stator coil and is positioned at the arc portion of both sides, top, and this top is positioned at above this stator coil relatively, and this top is provided with at least one perforation, each arc portion is extended towards this gap by this top, and being connected to form capping portion between the arc portion on each top, this capping portion is then corresponding will be closed above each gap, can reduce compressor noise and oil recycle ratio.

Embodiment
The present invention is improved mainly for the stator in Normal squeezing machine, as shown in Figure 1, this compressor is provided with a seal container 11 equally, the electric element 12 in order to drive is provided with in this seal container 11, this electric element 12 is provided with the stator 121 being mounted to ring-type by the inner face along seal container 11, and insert the rotor 122 be arranged at inside this stator 121, this rotor 122 is fixed wtih the rotating shaft 123 extended toward Vertical direction, this seal container 11 lower inside is provided with the rotary compression element 14 driven by the rotating shaft 123 of this electric element 12.
As shown in Figures 3 to 5, this stator 121 has circular iron core 126, and plural stator coil 124, this stator coil 124 is installed in most teeth portion 127 of these 126 inner circumferentials unshakable in one's determination with concentrated winding method, this stator 121 inside is formed with the gap 125 running through upper and lower between adjacent stators coil 124, and this iron core 126 is upper and lower is respectively equipped with upper and lower framework 15,16.
Focusing on of this case: be provided with a lid 20 above this stator 121, shown in Fig. 6, this lid 20 is provided with a ring limit 21 and can be fixed on this stator 121, this ring limit 21 is also formed with covering 22 towards this stator coil 124, this covering 22 is formed with top 221 along each stator coil 124 and is positioned at the arc portion 222 of both sides, top 221, and this top 221 is provided with at least one perforation 223, each arc portion 222 extends towards this gap 125 by this top 221, and has been connected to form capping portion 224 between the arc portion 222 on each top 221.
