The inlet end 151 of exhaustor 150 is arranged on lower flange deafener 140, lower flange deafener 140
On be provided with passage, when cylinder 120 works produce gas by this passage from the entrance point of exhaustor 150
Flowing into, this gas body 152 through exhaustor 150 port of export by exhaustor 150 are discharged, cylinder
The gas produced during 120 work has certain temperature, and body 152 is arranged in oil sump 111, and gas flows into
By the form of heat exchange, the heat of gas itself is passed to the refrigeration oil in oil sump 111 during Shi Guanti 152,
The temperature of the refrigeration oil in raising oil sump 111, and then ensure the temperature condensation temperature higher than refrigeration oil of refrigeration oil
Degree, makes rotary compressor 100 refrigeration oil when shutting down to reflux, it is ensured that rotary compressor 100 reliable
Property.
It is by upper flange plate 160 that gas in cylinder 120 is discharged by current rotary compressor 100
Offering what the mode of exhaust passage was carried out, gas is discharged along the direction of arrow shown in Fig. 1, and gas is by upper
Exhaust passage on ring flange 160 is discharged in the internal cavities of housing 110, and rotary compressor 100 is entering
During row low-temperature heating, can there is the condensation temperature being near or below freezing liquid in the temperature of the freezing liquid in oil sump 111
Degree, affects the reliability of rotary compressor 100.And the rotary compressor 100 of the present invention is by improving cylinder
The exhaust mode of gas in 120, gas is along the direction of arrow discharge shown in Fig. 2, Appropriate application expellant gas
Heat improve the temperature of the freezing liquid in oil sump 111, it is ensured that rotary compressor 100 is when low-temperature heating
Can normally work.Lower flange deafener 140 increases and has exhaustor 150, by exhaustor 150 by gas
The gas that cylinder 120 produces transfers heat to the freezing liquid in oil sump 111 in the way of heat exchange, improves pond
The temperature of interior freezing liquid, can also discharge gas simultaneously.
Further, the position at the air vent place of outlet side 153 is higher than the liquid level of refrigeration oil in oil sump 111
Highly.Require the position at air vent place of outlet side 153 higher than the liquid level of refrigeration oil in oil sump 111,
If the position at the air vent place of outlet side 153 is less than or equal to the liquid level of refrigeration oil in oil sump 111
Time, exhaustor 150 is installed on lower flange deafener 140, and body 152 is positioned at oil sump 111, now
The air vent of outlet side 153 also be located in oil sump 111, after injecting refrigeration oil in oil sump 111, body 152
Can immerse in refrigeration oil with outlet side 153, when the gas in cylinder 120 is discharged by exhaustor 150,
The refrigeration oil in oil sump 111 can be caused to roll, and the oil drain quantity causing rotary compressor 100 is high, and impact rotates
The performance of compressor 100 and the heat transfer effect of the heating of application rotary compressor 100 of the present invention.
As a kind of embodiment, body 152 is spiral coil pipe.So, gas is being discharged gas
Time in cylinder 120, exhaustor 150 by spiral body 152 transfer heat in oil sump 111 cold
Freeze oil.Spiral coil pipe is capable of heat transmission from bottom to top, is communicated up owing to warm-up movement has
Trend, it is ensured that in a vertical direction heating oil sump 111 in freezing liquid.Further, body 152
The number of turns of spiral be more than a circle or a circle.Body 152, for heating the freezing liquid in oil sump 111, is managed
The number of turns of the spiral of body 152 is The more the better, it is contemplated that the degree of depth of oil sump 111 and lower flange 130 arrive
Distance between at the bottom of oil sump 111 pond, the number of turns of the spiral of body 152 too much, oil sump 111 will be not placed into
In, therefore, in the present invention, the number of turns of the spiral of body 152 is a circle to three circles, by spiral
Body 152 heats the freezing liquid in oil sump 111, the temperature of freezing liquid in raising oil sump 111.At the present embodiment
