Description
Technical field
The present invention relates to the hermetic compressor comprising the insulation component be arranged on stator winding.
Background technology
For the stator of the motor of the hermetic compressor in refrigerating plant such as refrigerator by being placed into by the winding be made up of wire in the slit on the stator heap that is made up of magnetic sheet, and winding forms by extending through the opposite face of stator heap laterally the parts being called as winding head.And compression of metals machine body to be placed on stator and compressor block carries basic mechanical organ, such as cylinder, piston, crank and piston rod in hermetic compressor.Compressor block is arranged on stator heap to be positioned at the top of winding head.For security reasons, the space of minimum 2mm will be stayed between compressor block and winding head, to make not have current jump (electric leakage) when electric current is applied to stator winding between winding wire and body.In order to form described space, stator winding is pressed with the specified pressure that will be formed.In most of the cases, the number needs of stator winding will be increased for playing positive influences to the efficiency of air compressor motor; But need the safe space stayed between compressor block and winding to inhibit the quantity of winding to increase.In order to address this problem, in the prior art, be that the leptophragmata of 0.15-0.20mm is arranged between stator winding head and compressor block from the insulation component that plastic film is made by having thickness, but these insulation components being put into air compressor motor create problem in the labour that particularly produces in the shape due to winding head and compressor block.
In international patent application WO2008145760, describe the insulation component be rotated between coil core and winding head.This insulation component comprises the additional insulation extension of the peripheral edge regions be placed on coil core and the insulation provided between the flange extension of cylinder casing and winding head.
In US Patent No. 5957671, describe the film in the stator of the motor being used to compressor, which provide the insulation between winding head and compressor block, utilize the opening be arranged in the middle part of it to be attached it on the intracardiac strutting piece of compressor block by pressing.
Summary of the invention
The object of the invention is to realize a kind of hermetic compressor, it comprises the insulation component that can be placed to easily installing on stator winding.
Be implemented for reaching the object of the invention and comprising at the hermetic compressor that Section 1 claim and corresponding claim thereof illustrate: the stator with stator heap, the winding be made up of wire is placed on stator heap, form the winding head of the part that winding extends laterally from the upper surface that stator is piled, and the compressor block be placed on the upper surface of stator heap, and be made of plastics and be arranged on annular (ring-type) insulation component on winding head.
The vertical section with the insulation component of annular body is C shape downwardly, and insulation component has the groove be arranged on wherein, and winding head is arranged in groove.
In an embodiment of the present invention, insulation component is made up of heat-shrinkage material.In this embodiment, insulation component owing to being shunk by heating, to be bonded on winding head and to obtain permanent connection by adopting the shape of winding head after being mounted on winding head.
In another embodiment of the present invention, the opening that insulation component has the part by cutting away circumferential body and formed, and the electrical connection of the winding head extended laterally from winding head can be realized.Because opening is oriented to aim at the recess on compressor block, so there is no the risk of winding head at the region place contact compressor block that opening is arranged.
Insulation component is assembled to winding head, also provides insulation by covering winding head because its annular of surrounding winding as sleeve is easily mounted on winding head.At insulation component lash rope winding head thereon not needing winding is kept together.

Embodiment
The hermetic compressor 1 being suitable for using in refrigerating plant such as refrigerator comprises shell 2, be positioned at the stator 5 of shell 2, there is the stator heap 3 and the winding 4 of one or more than one that are made up of lamination, winding 4 is made up of the wire on the slit be wrapped on stator heap 3, form the more than one winding head 6 of winding 4 from the part oppositely facing outside extension of stator heap 3, and carry and/or support basic mechanical organ such as cylinder, piston, the compressor block 7 of crank and piston rod, be installed in stator heap 3 upside on the upside making its lower surface not contact winding head 6.
Hermetic compressor 1 of the present invention comprises annular (ring-type) insulation component 10, is made up of plastic material, to be arranged on winding head 6 and as sleeve, to surround winding head 6.
Insulation component 10 has main body 8, and its vertical section is C shape downwardly, and groove 9, is positioned at main body 8 and winding head 6 is set to groove.
Groove 9 moves away extended insulation component 10 to be mounted to winding head 6 each other by the arm and making stretching the main body 8 forming C shape, and insulation component 10 is easy to hand labour and in axial direction pushes by utilizing and be installed on winding head 6.
In one embodiment of the invention, insulation component 10 is made up of heat-shrinkage material.
In this embodiment, after insulation component 10 is mounted to winding head 6, stator 5 is placed in heating furnace, and its temperature is conditioned for this operation and insulation component 10 is heated.Be bonded to winding 4 and the shape adopting winding head 6 owing to adding thermal insulation element 10 by shrinking, and obtain permanent connection.
In one embodiment of the invention, the opening 11 that insulation component 10 comprises the part by excising main body 8 and formed, and when insulation component 10 is mounted to winding head 6, it aims at the electrical connection of the end of the winding 4 realizing extending laterally from winding head 6 by the part of the electrical connection of the end with formation winding 4.
In this embodiment, the region place of insulation component 10 not residing for opening 11 covers winding head 6.The end being extended winding 4 by the winding head 6 from the region residing for opening 11 laterally forms electrical connection.And the recess G of one or more than one is arranged on compressor block 7 to reduce the weight of material, as as shown in embodiment before, because opening 11 is aimed at the recess G on compressor block 7, therefore there is not the risk of the winding head 6 at the region place residing for compressor block 7 contact openings 11.
Insulation component 10 utilizes its annular with almost identical with winding head 6 size to be easily mounted on winding head 6, and the insulation provided between compressor block 7 and winding head 6 by covering winding head 6 as sleeve.In hermetic compressor 1 of the present invention, do not need to be positioned at by the lash rope that winding 4 keeps together on winding head 6, thus provide lash rope material and engage the saving of labour.
Be appreciated that the present invention is limited by disclosed embodiment above and those skilled in the art can introduce different embodiments easily.These embodiments should be taken into account in by the claimed scope of claim of the present invention.
