Abstract
The invention discloses an enclosed type rotating compressor comprising a casing, wherein, the casing is composed of a cylinder body, an upper cap and a lower cap, a motor assembly and a compressor assembly are mounted in the casing, the motor assembly is composed of a stator, a rotor and a crankshaft; the compressor assembly is composed of a cylinder, an upper bearing and a lower bearing, a discharge pipe is arranged on the upper cap, a lower end of the air discharge pipe is leveling with an inner wall of the upper cap, an inner baffle plate is arranged inside the compressor casing and belowthe lower end of the discharge pipe. Because of arranging the inner baffle plate below the lower end of the discharge pipe, the invention can block the injection of the lubricating oil and improve therefrigeration capability of the compressor, meanwhile, because of the shortening of the discharge pipe, the consumption of the copper can be saved, and the product cost is reduced.
Description
Technical field
The invention belongs to a kind of compressor, be specifically related to a kind of bottom and be provided with internal baffle, stop the ejection of Run lubricating oil, so that improve the closed rotary compressor of electric efficiency in the discharge tube lower end.
Background technique
As shown in Figure 1, the compressor of prior art, the upper inside that is included in housing 1 is equipped with electric machine assembly 20, at the downside of electric machine assembly 20 compressor assembly 30 that is equipped with separated by a distance.Housing 1 is made up of cylindrical drum 11, loam cake 12 and the lower cover 13 etc. of hollow.Electric machine assembly 20 is pressed on the inner peripheral surface that is fixed on cylindrical shell 11, and it is made up of stator 21, rotor 22 and rotary crankshaft 23 of being pressed into the center that is fixed on rotor 22 and transmitting rotating force etc.
In addition, be provided with exhaust port (not shown) in the upper bearing 32, its upside binding is fixed with baffler 34, is used to reduce the noise that is produced by pressure difference from the compressed media gas of exhaust port discharge.For making dielectric gas be discharged to seal casinghousing 1 outside by baffler 34, on loam cake 12, be provided with discharge tube 50, on loam cake 12, also be provided with the wiring terminal 51 that connects power line, be provided with suction pipe 40 in the bottom of seal casinghousing 1.
But, in the closed rotary compressor of prior art, discharge tube 50 directly is inserted into the inside of housing 1 by loam cake 12, this structure not only makes discharge tube 50 longer, the use amount of copper increases, and the discharge capacity that is mixed in the lubricant oil in the compressed media is increased, and lubrication oil consumption is accelerated, be unfavorable for the operation of compressor, reduce the refrigerating capacity of compressor.
Summary of the invention
The present invention is for the shortcoming that overcomes prior art proposes, and its objective is provides a kind of bottom in the discharge tube lower end to be provided with internal baffle, stops the ejection of Run lubricating oil, so that improve the closed rotary compressor of electric efficiency
Technological scheme of the present invention is: a kind of closed rotary compressor, comprise housing, housing is made up of cylindrical shell, loam cake and lower cover etc., motor and compressor assembly are installed in housing, motor is made up of stator, rotor and bent axle etc., and compressor assembly is made up of cylinder, upper bearing and lower bearing etc., and loam cake is provided with outlet pipe, the lower end of described discharge tube is concordant with the inwall of loam cake, below the discharge tube lower end, the inside of compressor housing is provided with internal baffle.The flange connector that internal baffle is formed with by arch portion with in the underpart of arch portion to the plane shape of extension Shen forms.
Arch portion is the shape that raises up of approximate half-circular.
Arch portion is the approximate half elliptic shape that raises up.
Internal baffle forms with metallic plate punching is whole.
Internal baffle is with forming with the engineering plastics integral molded plastic.
The present invention has stopped the ejection of lubricant oil owing to be provided with internal baffle below the discharge tube lower end, has improved the refrigerating capacity of compressor; Because discharge tube shortens, save the consumption of copper simultaneously, reduced product cost.

Embodiment
Below, with reference to drawings and Examples closed rotary compressor of the present invention is elaborated:
Shown in Fig. 2～7, closed rotary compressor of the present invention comprises housing 1, in the upper inside of housing 1 electric machine assembly 20 is installed, at the downside of electric machine assembly 20 compressor assembly 30 that is equipped with separated by a distance.Housing 1 is made up of cylindrical drum 11, loam cake 12 and the lower cover 13 etc. of hollow.Electric machine assembly 20 is pressed on the inner peripheral surface that is fixed on cylindrical shell 11, and it is made up of stator 21, rotor 22 and rotary crankshaft 23 of being pressed into the center that is fixed on rotor 22 and transmitting rotating force etc.
In addition, be provided with exhaust port (not shown) in the upper bearing 32, its upside binding is fixed with baffler 34, is used to reduce the noise that is produced by pressure difference from the compressed media gas of exhaust port discharge.For making dielectric gas be discharged to seal casinghousing 1 outside by baffler 34, on loam cake 12, be provided with discharge tube 50, on loam cake 12, also be provided with the power-line terminal 51 that connects power line, be provided with suction pipe 40 in the bottom of seal casinghousing 1.
The present invention has stopped the ejection of lubricant oil owing to be provided with internal baffle below the discharge tube lower end, has improved the refrigerating capacity of compressor; Because discharge tube shortens, save the consumption of copper simultaneously, reduced product cost.
