The central point of roof puts and has seted up the blast pipe mounting hole, install the blast pipe in the blast pipe mounting hole, the bottom surface of roof is provided with arc baffle, arc baffle is located blast pipe mounting hole one side.
Further, the axis of the exhaust pipe mounting hole coincides with the axis of the side plate.
Further, the outer wall of blast pipe and roof fixed welding, blast pipe one end is located the top cap, and the outside of top cap is stretched out to the other end.
Further, an electric connector mounting hole is further formed in the top plate, and the electric connector mounting hole is located on one side of the exhaust pipe mounting hole.
Further, an electric connector is arranged in the electric connector mounting hole, and the side wall of the electric connector is fixedly connected with the top plate.
Further, the arc baffle is arranged perpendicular to the top plate.
Further, the arc baffle is curved to a side away from the exhaust pipe mounting hole.
Further, the arc baffle is arranged opposite to the electric connector.
In a second aspect, embodiments of the present disclosure also provide a compressor, including a rotary compressor top cover as described above, further including a shell, the shell being sleeved outside the top cover side plate.
Further, the shell is welded and fixed with the top cover side plate.
Compared with the prior art, the utility model has the beneficial effects that:
According to the utility model, the arc-shaped baffle is arranged on the bottom surface of the top cover and is positioned on one side of the exhaust pipe, part of oil can be blocked by the arc-shaped baffle due to the action of the arc-shaped baffle in the process of sucking and exhausting the gas refrigerant and the gas refrigerant can be normally exhausted from the exhaust pipe, so that the oil circulation rate is reduced to a certain extent, the whole height of the compressor is not required to be increased, and the production cost of the compressor is reduced.
