Embodiment
Now, with reference to accompanying drawing the preferred embodiments of the present invention are described.
Fig. 3 is the face upwarding stereogram of fixed scroll of the present invention.Fig. 4 is the stereogram of fixed scroll among Fig. 3, and this fixed scroll is connected with mainframe.
As shown in Figure 3 and Figure 4, the fixed scroll 1 of scroll compressor comprises: scrollwork body 10, and it is arranged on the upper surface of mainframe 2 and is limited with compression chamber 11 therein; And the suction portion 20 of damming, this suction portion 20 of damming is formed on the scrollwork body 10 gaseous refrigerant is imported compression chamber 11.
The suction gaseous refrigerant that this suction portion 20 of damming is used for only will upwards guiding from the suction baffle plate 2a that is formed at mainframe 2 one sides guides to compression chamber 11, prevents from simultaneously to import in the compression chamber 11 around scrollwork body circuit residue gaseous refrigerant.Here, sucking baffle plate 2a has recessed shape and is configured to extend to the suction portion 20 of damming.The suction portion 20 of damming comprises the remaining dividing plate (barrier) of excision after the part of these scrollwork body 10 formed mounting flanges 13 bottoms, to form suction passage 21 corresponding to the position that sucks baffle plate 2a upper end.This suction passage 21 is configured to be communicated with compression chamber 11.
Employing is by the suction portion 20 of damming of above-mentioned structure, and the gaseous refrigerant that upwards guides along the suction baffle plate 2a that is formed at mainframe 2 one sides impacts dividing plate 22 so that it directly guides in the compression chamber 11 by suction passage 21.And this dividing plate 22 prevents to import suction passage 21 around scrollwork body 10 circuit heated gaseous refrigeration agents.
One side of suction passage 21 is formed with predetermined inclination from scroll 12 terminal plane of inclination 23 of extending continuously.The opposite side of suction passage 21 also is formed with a plane of inclination 24 that tilts with predetermined inclination with respect to plane of inclination 23.
Plane of inclination 23 and 24 is used to make gaseous refrigerant more successfully to import by suction passage 21 in the compression chamber 11 defined in the scrollwork bodies 10 from the suction baffle plate 2a of mainframe 2.
Fig. 5 is the longitudinal section of the importing of gaseous refrigerant of the present invention.
As shown in Figure 5, import to suction gaseous refrigerant in the housing 3 by being arranged to and upwards guided via being located at suction pipe 3a on the housing 3 towards the suction baffle plate 2a of the mainframe 2 of suction pipe 3a.Upwards the gaseous refrigerant of guiding impacts dividing plate 22, is imported in the compression chamber 11 of the scroll 12 that is formed on the scrollwork body 10 by suction passage 21 thus.
On the other hand, the residue gaseous refrigerant that guides downwards along suction baffle plate 2a is heated and circulates in compressor simultaneously.Then, the gaseous refrigerant of heating is upwards guided, and around 10 circulations of scrollwork body.In such cases, because dividing plate 22 has blocked the passage that leads to suction passage 21, the gaseous refrigerant of heating can not guide in the compression chamber 11.As a result, the suction portion 20 of damming of the present invention makes and is drawn in the housing 3 and impacts the gaseous refrigerant that sucks baffle plate 2a and can directly import in the compression chamber 11 by dividing plate 22 and suction passage 21, prevents the importing of the gaseous refrigerant of heating in housing 3 simultaneously fully.
From the above description obviously as can be seen, the invention provides a kind of fixed scroll of scroll compressor, this fixed scroll can make the gaseous refrigerant of suction successfully import in the compression chamber, simultaneously prevent to import the residue gaseous refrigerant that in compressor, heats fully, therefore, reach the more stable importing of gaseous refrigerant and improved the volumetric efficiency of compressor, thus the compressor performance that is improved.
In addition, according to the present invention, the simple change by the fixed scroll shape need not to install additional element, and this fixed scroll is just realized easily that the gaseous refrigerant that will suck is directed into effectively and prevented simultaneously the importing of heated gaseous refrigeration agent in the compression chamber fully.This just has the effect of simplifying manufacture process and reducing manufacture cost.
Although the description-based purpose of the preferred embodiments of the present invention discloses, but those skilled in the art should be realized that, only otherwise break away from, can carry out various modifications, increase and replacement to the present invention as the disclosed scope and spirit of the present invention of appended claims.
