Below operational circumstances in the closed compressor with above-mentioned formation and effect thereof are described.
When having power supply to supply with in the stator 107, rotor 108 and bent axle 111 will produce rotation, and eccentric motion takes place eccentric part 114, and makes piston 115 reciprocating in cylinder 109 through connecting rod means 116.When piston 115 is reciprocating, in suction stroke, the refrigerant 106 that turn back to from the cooling system (not shown) in the can 101 will flow through inhaling silencer 132 and back down suction reed 121, be inhaled into cylinder 109 by suction port 122 again.In compression stroke, the refrigerant 106 of suction is backed down exhaust reed 142 by compression in cylinder 109, is discharged in the hyperbaric chamber 125 that forms cylinder head 126 from exhaust port 128, is discharged in the cooling system (not shown) afterwards again.
In addition, along with the rotation of bent axle 111, fuel supply line 117 also will rotate, and rely on centrifugal force that lubricant oil 104 is upwards smoked, and supply to places such as each slide member of compressing mechanism 102 and discharge valve apparatus 123.
The switching part 148 of exhaust reed 142 is closed in suction stroke, with valve seat part 134 sealings; In compression stroke, when the pressure in the cylinder 109 rises, will open again, refrigerant 106 is discharged in the hyperbaric chamber 125.Because switching part 148 sides of exhaust reed 142 being provided with like that as shown in Figure 2 towards the exhaust reed dogleg section 152 of valve seat part 134 1 side bendings, therefore have and push the strength of valve seat part 134 to and having an effect, float from valve seat part 134 in the down periods so can prevent exhaust reed 142 with opening and closing part 148.Like this, in suction stroke, can reduce from hyperbaric chamber 125 adverse currents of cylinder head 126 to cylinder the amount of the high-pressure refrigerant 106 in 109, thereby can obtain very high volumetric efficiency.
In addition, because switching part 148 1 sides in the exhaust reed 142 are provided with towards the exhaust reed dogleg section 152 of valve seat part 134 1 side bendings, therefore, during the switching part 148 of exhaust reed 142 being opened like that as shown in Figure 4, exhaust reed dogleg section 152 bends with fulcrum, increases gradually from exhaust reed dogleg section 152 to the front end curvature that opens and closes part 148.Like this, when exhaust reed 142 was run into spring reed perk part 156, the angle that is made of exhaust reed 142 and spring reed perk part 156 will increase.Like this, between the front end of the switching part 148 of exhaust reed 142 and the spring reed perk part 156 with origination point contact, can reduce to occur when the approaching face contact conditions take place for exhaust reed 142 and spring reed perk part 156, because of the phenomenon of clinging that existence such as lubricant oil 104 occur is arranged in the middle of it.The responsiveness of exhaust reed 142 can improve, close work slowly phenomenon can alleviate, volumetric efficiency can further improve.
In addition, be arranged in yielding space 140 by the exhaust reed dogleg section 152 that makes exhaust reed 142, can prevent that when fixing exhaust reed 142 exhaust reed dogleg section 152 from being taken place by the phenomenon that base part 138, spring reed fastening part 158 and catch fastening part 162 are compressed, therefore can make the inclination amount of exhaust reed 142 keep stable.Like this, can make the impacting force that acts on the valve seat part 134 reach setting value, thereby make the sealability between exhaust reed 142 and the valve seat part 134 become more reliable.
Form predetermined gap between the switching part 148 of spring reed perk part 156 and exhaust reed 142 and the catch 146, be skewed with respect to the plane at valve seat part 134 and base part 138 places.Therefore, exhaust reed 142 has before running into spring reed perk part 156 rigidity characteristic lower, higher again 2 stages of rigidity after running into, therefore both can not lose responsiveness, exhaust reed 142 is opened again easily under the few condition of refrigerant circulation quantity, thereby can reach very high compression efficiency.
Here, by making spring reed dogleg section 154 be positioned at the top of base part 138, can make between exhaust reed 142 and the spring reed 144 at yielding 140 places, space and keep certain clearance reliably, therefore, can make the elastic characteristic of exhaust reed 142 keep stable, thereby can keep very high, very stable efficient.
In addition, because exhaust port 128 is located on the valve plate 120 in the recess 124 with cylinder 109 opposite sides, therefore, the length of exhaust port 128 has been shortened, refrigerant 106 amounts that remain in after the compression in exhaust port 128 parts also can reduce, and are suppressed at that these refrigerant 106 when air-breathing once more exapnsion take place and effect that the volumetric efficiency that causes descends thereby can produce.
Also have, since in the stop portion 160 with exhaust reed 142 facing to the side be arranged to plane almost parallel with valve seat part 134 and base part 138 places, therefore, spatial altitude with respect to the switching part 148 of spring reed perk part 156 and exhaust reed 142 is controlled easily, and energy efficiency inequality and noise inequality can be reduced.
Adopt the above embodiment of the present invention, can realize a kind of closed compressor with very high energy efficiency.
Application of the present invention is as follows.Closed compressor among the present invention can also be applicable in the equipment such as freezing display case unit and dehumidifier because therefore decline that can the freezing-inhibiting ability and realize high efficiency, not only can be used in refrigerator.
