Description
Technical field
The utility model relates to the Compressor Technology field, and the rotary compressor of oil mass is told in specifically a kind of reduction.
Background technique
Rotary compressor is when carrying out exhaust, and vaporific refrigeration oil can part enter in the air-conditioning system with gaseous coolant, and forms oil film in the inwall of the connecting tube of air-conditioning system, makes the heat transfer effect variation of air conditioner two-unit (vaporizer and condenser); Therefore, compressor is told the direct performance that affect compressor of size meeting of oil mass.In addition, oil extraction also can affect the reliability of compressor, the air-conditioning of the high drop of two devices, also can because of the oil return difficulty makes compressor can't long-play.
In conventional art, be to solve above-mentioned technical problem by oil separator is set outside compressor.Seeing also application number is No. 200910038552.0 Chinese patent application, discloses a kind of shell low-pressure rotary compressor.This technological scheme is exactly to separate refrigeration oil in the refrigerant by external oil separator.But, adopting this technological scheme more complicated, external oil separator has not only increased the volume of compressor, and extra oil separator has increased the manufacture cost of compressor.
The model utility content
For above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of and utilizes spiral helicine breathing pipe reduction to tell the rotary compressor of oil mass.
The purpose of this utility model is achieved by the following technical solution:
The rotary compressor of oil mass is told in a kind of reduction, comprise compressor, the compression assembly that is provided with upper chamber, motor in the housing of this compressor, joins with this motor and the oil-in chamber of being located at this compression assembly lower end, be provided with oil separating device in the described upper chamber, this oil separating device is communicated with this oil-in chamber.
As optimal technical scheme of the present utility model, described oil separating device comprises oil return tank and breathing pipe; This oil return tank is provided with relief opening and suction port, and this relief opening is communicated with outlet pipe in extending to upper chamber; This breathing pipe, its in the shape of a spiral, this breathing pipe is located in this oil return tank, an end of this breathing pipe is connected with suction port on the oil return tank, the other end is positioned at the bottom of this oil return tank; And this oil return tank links to each other with this oil-in chamber by return tube.
As optimal technical scheme of the present utility model, described relief opening is located at the top of oil return tank.
As optimal technical scheme of the present utility model, described suction port is located at the sidewall of oil return tank, and the center of the position deviation compressor of this suction port, and with upper chamber in the air-flow that rotates tangent.
As optimal technical scheme of the present utility model, when the sense of rotation of described breathing pipe spiral and compressor operating, the direction of its motor rotation is consistent.
As optimal technical scheme of the present utility model, the diameter of described breathing pipe is greater than the diameter of this outlet pipe.
Compared with prior art, the utility model is simple in structure, effectively reduces the oil mass of telling of compressor; Simultaneously, the gaseous coolant of high pressure is discharged the exhaust noise that has also reduced compressor through spiral helicine breathing pipe, has improved the performance of compression.
Description of drawings
Fig. 1 is the generalized section of compressor in the utility model.
Fig. 2 is the generalized section of oil return tank and breathing pipe in the utility model.
Fig. 3 is the plan view of oil return tank and breathing pipe in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
See also Fig. 1 to Fig. 3, comprise compressor, be provided with upper chamber 102, motor 103 in the housing 101 of this compressor, the compression assembly 105 that joins with this motor 103 and the oil-in chamber 104 of being located at these compression assembly 105 lower ends.
Be provided with oil separating device in the described upper chamber 102, this oil separating device comprises oil return tank 106, and this oil return tank 106 is metal can, for reducing production costs these oil return tank 106 general iron flasks that adopt.Be provided with relief opening 107 on the top of this oil return tank 106, this relief opening 107 is communicated with outlet pipe 110 in extending to upper chamber 102.Suction port 108 is located at the sidewall of this oil return tank 106, and the center of the position deviation compressor of this suction port 108 (take the center line 109 of compressor as benchmark), and tangent (during compressor operating with the air-flow of upper chamber 102 interior rotations, upper chamber 102 is interior can to produce swirling eddies), be beneficial to and reduced exhaust resistance.
Breathing pipe 111 in the shape of a spiral, when the sense of rotation of its spiral and compressor operating, the direction of its motor 103 rotations is consistent; Simultaneously, the diameter of this breathing pipe 111 is greater than the diameter of this outlet pipe 110.This breathing pipe 111 is located in this oil return tank 106, and an end of this breathing pipe 111 is connected with suction port 108 on the oil return tank 106, and the other end is positioned at the bottom of this oil return tank 106; And this oil return tank 106 links to each other with this oil-in chamber 104 by return tube 112.
During compressor air-discharging, be full of gaseous coolant and vaporific refrigeration oil in the upper chamber 102; At this moment, gaseous coolant and vaporific refrigeration oil are in suction port 108 enters into spiral helicine breathing pipe 111, in flow process through sedimentation, bump, adhesive attraction, the inwall that vaporific refrigeration oil sticks to breathing pipe 111 forms oil droplet, and flow to the bottom of oil return tank 106, be introduced into by return tube 112 in the oil-in chamber 104 of compressor lower end; And gaseous coolant is discharged through outlet pipe 110.This kind structural design can not brought to outlet pipe 110 with the gaseous coolant secondary vaporific refrigeration oil into, and gaseous coolant and vaporific refrigeration oil are separated fully, effectively reduces the oil mass of telling of compressor; Simultaneously, the gaseous coolant of high pressure is discharged the exhaust noise that has also reduced compressor through spiral helicine breathing pipe 111.
The above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
