Based on above reservoir function demand, the reservoir needs to have certain liquid separating ability and stock solution volume. The liquid separating capacity of the liquid storage device mainly depends on the relative position of the air inlet pipe and the exhaust pipe of the liquid storage device, and the refrigerant flowing out of the air inlet pipe is prevented from directly entering the exhaust pipe, so that a filter screen assembly is arranged in the air inlet pipe and the exhaust pipe, the filter screen assembly conducts the refrigerant flowing out of the air inlet pipe to the two sides of the exhaust pipe, after the refrigerant is subjected to gas-liquid separation under the action of inertia acting force and gravity, the gaseous refrigerant flows into the compressor body through the exhaust pipe. The liquid separating capacity of the liquid storage device is strong and weak, and the distance between the diameter of the exhaust pipe and the upper end of the exhaust pipe is far away from the filter screen component is as follows: the exhaust pipe diameter is the smaller and the distance between the upper end of the exhaust pipe and the filter screen assembly is the smaller, under the condition that the diameter of the central shunting structure of the filter screen assembly is unchanged, the risk that a refrigerant directly enters the exhaust pipe is the smaller, and the liquid separation effect of the liquid storage device is the better.

Detailed Description

Referring collectively to fig. 1-7, according to an embodiment of the present application, a compressor reservoir assembly includes:

the filter screen component 12 is arranged in the cylinder body 1 and is opposite to the outlet end of the air inlet pipe 11; the screen assembly 12 includes a flow guide portion 121 and a filter portion 122, and the flow guide portion 121 guides the gas of the gas inlet pipe 11 to the filter portion 122;

the inlet end of the exhaust pipe is opposite to the flow guide part 121, and a groove 131 in the axial direction of the exhaust pipe is formed in the inlet end.

In the barrel 1 of the compressor liquid storage device, the flow guide part 121 in the filter screen assembly 12 guides the gas sent by the gas inlet pipe 11 to the filter part 122, so that the gas in the gas inlet pipe 11 is prevented from directly entering the gas outlet pipe. As shown in fig. 1 and 2, after the gas is separated into gas and liquid in the filtering portion 122, the liquid drops fall and the gas rises to the inlet of the exhaust pipe blocked by the flow guide portion 121, and finally is led out of the reservoir through the exhaust pipe.

The pressure pulsation loss in the accumulator is related to the refrigerant flow path length, and the longer the flow path length, the larger the pressure pulsation loss. The arrangement of the groove 131 reduces the length of the circulation path of the gaseous refrigerant in the liquid accumulator, can effectively reduce pressure pulsation loss, correspondingly adjusts the distance of the exhaust pipe relative to the filter screen assembly 12, and does not influence the liquid separating capacity of the liquid separator.

The arrangement of the groove 131 can move the upper end space of the exhaust pipe downwards without increasing pressure pulsation loss (ensuring that the length of a flow path of air flow in the liquid storage device is unchanged), reduce the distance between the exhaust pipe and the filter screen assembly 12, and further increase the liquid separating capacity of the liquid separator.

Because this application sets up recess 131 at this entry end for the local and the increase of the space between water conservancy diversion portion 121 of entry end, consequently can reduce blast pipe and the distance of water conservancy diversion portion 121, increased relatively and divided the liquid ability, even under the condition that does not change and divide the liquid ability, reduced gaseous circulation path length, can effectively reduce pressure pulsation loss.

In some embodiments, one vent tube is provided, and the groove 131 is provided along a sidewall of the vent tube.

As shown in fig. 1 and 3, in the reservoir of the compressor, a single exhaust pipe structure is adopted, a groove 131 is arranged on the side wall of the inlet end of the exhaust pipe, and the depth of the groove 131 is along the axial direction of the inlet end; one recess 131 may be provided, or at least two recesses 131 may be provided.

In case a plurality of grooves 131 is provided, all grooves 131 are evenly distributed over the inlet end.

In some embodiments, the distance L1 between the two sides of the groove 131 is less than or equal to the inner diameter of the exhaust pipe.

The width of the groove 131 is too large, which may affect the liquid separating capability of the liquid reservoir, and the refrigerant separated from the filter screen assembly 12 may easily enter the exhaust pipe directly without completing the gas-liquid separation. Preferably, the groove 131 of the single exhaust pipe has a square cross-section.

In some embodiments, there are at least two exhaust pipes, each exhaust pipe has a gap, and all the gaps form the groove 131 in combination.

As shown in fig. 4-7, the liquid storage device of the compressor adopts a double exhaust pipe structure, the groove 131 is formed by combining the openings of the exhaust pipes, for example, the first exhaust pipe 13 is provided with a first opening 132, the second exhaust pipe 14 is provided with a second opening 141, and the first opening 132 and the second opening 141 form the groove 131; while the recess 131 is located at a middle position of all the exhaust pipes, it further prevents the problem of liquid droplets entering the exhaust pipes with respect to the arrangement at the outer periphery.

In some embodiments, a distance L1 between two sides of each notch is smaller than or equal to the inner diameter of the exhaust pipe.

The width of the groove 131 is too large, which may affect the liquid separating capability of the liquid reservoir, and the refrigerant separated from the filter screen assembly 12 may easily enter the exhaust pipe directly without completing the gas-liquid separation.

In some embodiments, the distance between the center of all the exhaust pipes and the center of the cylinder 1 is set to be the same.

Let all blast pipes be for even setting, can guarantee that recess 131 is in the central point of barrel 1 and puts, just in time is located the position that water conservancy diversion portion 121 sheltered from completely, avoids the liquid drop to get into.

Preferably, the shape of the notch along the circumferential direction of the exhaust pipe is arc-shaped or square-shaped.
