Abstract
A valve unit for enclosed rotary compressor is disclosed, In order to control the open and close of the exhaust hole on upper bearing, a switch plate is installed to the pointed position on mainshaft in compressing chamber. When main shaft is rotating, the exhaust hole is periodically opened and closed by said switch plate to exhaust the high-pressure gas from compressing chamber. Its advantages are no noise and not possessing space.
Description
Technical field
The invention belongs to closed rotary compressor valving class, relate in particular to the device of the closed rotary compressor valve that sends impact noise when preventing valve motion.
Background technique
Seal container (1) inside of the closed rotary compressor at present, (referring to Fig. 1, Fig. 2) is provided with:
By the drive motor that stator (3) and rotor (2) constitute, main shaft (5) is connected with rotor (2) by the axle sleeve (2a) perpendicular to rotor (2).
Main shaft (5) lower end is provided with eccentric shaft (6), and the outside of this eccentric shaft (6) is with rolling piston (7).In order to form pressing chamber (8), be provided with the compressor body (12) that constitutes by cylinder (9) and metal (upper (10), (11) with the rotation compressed refrigerant of rolling piston (7).
The outlet port of the exhaust port (10a) on above-mentioned upper bearing (metal) (10) is provided with the valve sets (15) that is made of valve (13) and pad (14), and baffler (16) is arranged above this valve sets (15).
Being provided with outside the suction port (9a) of cylinder (9) ins succession prevents the liquid storage tank that coolant flows into.Be provided with the outlet pipe (18) that compressed high pressure refrigeration gas is discharged outward in the compressor body (12) above the seal container (1).
Aforesaid mechanism, after closed rotary compressor was connected power supply, the rotor (2) of drive motor (4) began rotation, was connected the also rotation thereupon of main shaft (5) on the rotor (2).
Rotation with main shaft (5), the eccentric shaft (5a) of main shaft (5) lower end drives cover rolling piston (7) in the above and rotates together, refrigeration gas, be compressed into the refrigeration gas of High Temperature High Pressure by the low-temp low-pressure in suction port (9a) the inspiration pressing chamber (8) of cylinder (9).When the refrigeration gas of compressed High Temperature High Pressure by valve sets (15), by the through hole (16a) of baffler (6), flow in the seal container (1), discharge outward from outlet pipe (18) by the slit between rotor (2) and the stator (3) again.
But, the closed rotary compressor of above-mentioned formation has a shortcoming, when discharging refrigeration gas, because of producing impact noise between the opening and closing pad (14) of valve (13) and the upper bearing (metal) (10), and the volume of exhaust gear also has influence on the raising of the compression efficiency of compressor.
Summary of the invention
The purpose of this invention is to provide a kind of valve unit of sealed rotary compressor, the discharge noise that it produces in the time of reducing to discharge refrigeration gas, the volume of elimination exhaust gear, and the rising that can also improve compressor operating efficient.
The object of the present invention is achieved like this, a kind of valve unit of sealed rotary compressor, it is provided with outlet pipe above seal container, and its internal upper part is fixed with drive motor, bottom is fixed with cylinder in it, and the cylinder place is provided with a suction port and is communicated to liquid storage tank by pipeline.The main shaft lower end of drive motor is provided with eccentric shaft, and eccentric shaft is outside equipped with rolling piston.Place, upper and lower part at cylinder and main shaft rolling piston is provided with upper bearing (metal) and lower bearing respectively, and upper bearing (metal) is provided with an exhaust port and is equipped with baffler.The present invention is provided with a switch plate at its position in appointment of described main shaft.
Switch plate of the present invention is that disk is provided with a discharge zone.
Because the present invention has adopted above technological scheme, on the appointed part of the main shaft (105) of pressing chamber inside, be provided with the switch plate that can rotate with main shaft, switch plate is discharged the pressurized gas of pressing chamber (108) lining with main axis rotation opening and closing exhaust port periodically.Because of valve impacts the noise that sends, also eliminated the volume that valve accounts for, thereby improved the efficient of compressor when so not only having prevented exhaust in the past.

Mode of execution
Tell about closed rotary compressor valving of the present invention in more detail below in conjunction with accompanying drawing.
Explanation among Fig. 1, Fig. 2 is described in detail in " background technique ", in this omission.
In Fig. 3, Fig. 4, seal container (101) inside is provided with the drive motor (104) that is made of rotor (102) and stator (103).Be connected with main shaft (105) by key (102a) perpendicular to rotor (102).The lower end of above-mentioned main shaft (105) is provided with eccentric shaft (106), and rolling piston (107) is being overlapped in eccentric shaft (106) outside.
And the compressor body by cylinder (109) and upper and lower bearing (110), (111) are formed has constituted the pressing chamber (108) along with the rotation compression refrigeration gas of rolling piston (107).The exhaust port (110a) that pressurized gas in the discharge pressing chamber (108) are arranged on the above-mentioned upper bearing (metal) (110), and exhaust port (110a) is provided with the baffler (113) that reduces exhaust noise.
