Based on this, the utility model provides a compressor aims at simplifying the structure of compressor to reduce the manufacturing cost of compressor.

With continuing reference to fig. 1 to 18, in order to achieve the above object, the present invention provides a compressor 10 including a compression main body 100 and a reservoir 200, wherein the compression main body 100 has a lower port 101; the reservoir 200 has an upper face 201, and the upper face 201 closes the lower port 101.

The compressor 10 is classified into a piston compressor 10, a screw compressor 10, a centrifugal compressor 10, a linear compressor 10, and the like. The piston compressor 10 generally consists of a housing, a motor, a cylinder, a piston, control equipment (starter and thermal protector) and a cooling system. The cooling modes include oil cooling, air cooling and natural cooling. The present invention relates to a compressor 10 that uses oil cooling.

Generally, the compression body 100 includes a compression assembly 120 and a main casing 110, the main casing 110 forms an installation cavity, the compression assembly 120 is disposed in the installation cavity, and the compression assembly 120 is generally disposed at a lower portion of the main casing 110 because the compression assembly 120 has a certain weight, which can reduce the center of gravity of the high pressure casing and also reduce the noise of the compressor 10. Generally, the compressing assembly 120 includes a compressor 121 and a motor 122, the compressor 121 has a rotating shaft connected to a rotor of the motor 122, and the motor 122 drives the rotating shaft to rotate so that the compressor 121 compresses gas, that is, the gas is compressed by the compressor 121. In other embodiments, the compression pump 121 may compress the gas in other manners, which are not described herein. In addition, the compression pump 121 generally has a low pressure gas inlet generally called a suction port 102, the suction port 102 communicates with the tank, a high pressure gas outlet communicates with the installation cavity, and the main casing 110 is also provided with a discharge port communicating with the installation cavity, the discharge port also communicating with a discharge pipe, thereby discharging the high pressure gas in the main casing 110.

In this embodiment, the accumulator 200 is used to store liquid, typically liquid refrigerant and lubricant oil, to reduce the temperature of the gas passing through the accumulator 200 and reduce the oil content of the gas. Specifically, the liquid storage device 200 has a liquid storage cavity 202, and an air inlet and an air outlet which are communicated with the liquid storage cavity 202, the air inlet is connected with an air inlet pipe 400, the air inlet pipe 400 is connected with an air source, and the air source is generally an air flow after the air discharged from an air outlet passes through other areas; the gas outlet is communicated with the suction port 102 of the compression pump 121 through the connection pipe 300, so that the gas cooled by the reservoir 200 is sent into the compression pump 121, and then the rotation shaft is driven to rotate by the starting motor 122 to compress the gas in the compression pump 121.

Further, in order to simplify the structure of the compressor 10, the cost is reduced. In this embodiment, the compression body 100 has a lower port 101, the compression body 100 includes a compression assembly 120 and a main housing 110, the lower port 101 is located on a bottom surface of the main housing 110, the reservoir 200 has an upper end surface 201, and the upper end surface 201 closes the lower port 101. That is, the compressing body 100 is mounted on the accumulator 200, and in this case, the accumulator 200 is equivalent to a mounting seat in addition to a container for storing the liquid, thereby reducing the mounting seat originally used for fixing and mounting the compressing body 100, simplifying the structure of the compressor 10, and reducing the material cost of the compressor 10. Meanwhile, since the liquid reservoir 200 is filled with liquid during normal operation, the center of gravity of the compressor 10 can be lowered, thereby improving the stability of the compressor 10 and reducing the noise of the compressor 10.

In addition, in this embodiment, the lower port 101 is located on the bottom surface of the main housing 110, and the reservoir 200 has an upper end surface 201, and the upper end surface 201 closes the lower port 101. In this way, by closing the lower port 101 of the main casing 110 with the casing of the accumulator 200, the number of components originally used to seal the lower port 101 of the main casing 110 is reduced, thereby simplifying the structure of the compressor 10 and further reducing the material cost of the compressor 10.

It is understood that the lower port 101 has many forms, and may be an opening or an opening, where the bottom surface of the main housing 110 is open, and the opening is opposite to the opening, that is, the opening is not completely open. Preferably, the lower port 101 is in an open form, which saves most material cost and simplifies the manufacturing process.

The technical scheme of the utility model through arranging the reservoir 200 in the below of compression main part 100 to the lower port 101 that the reservoir 200 will compress main part 100 is sealed. In this way, the accumulator 200 serves as a container for storing liquid and also serves as a mounting seat, thereby reducing the mounting seat originally used for fixing and mounting the compression body 100, simplifying the structure of the compressor 10, and reducing the material cost of the compressor 10. In addition, the lower port 101 of the main housing 110 is closed by the housing of the accumulator 200, so that the number of components originally used for sealing the lower port 101 of the main housing 110 is reduced, the structure of the compressor 10 is simplified, and the material cost of the compressor 10 is further reduced. Finally, placing the accumulator 200 below the compression body 100 also allows to reduce the radial dimensions of the compressor 10.

Referring to fig. 3, 12 and 14, in order to improve the stability of the compressor 10 and to ensure the amount of liquid stored in the liquid storage tank. In an embodiment, the outer diameter of the radial cross-section of the reservoir 200 is greater than the outer diameter of the radial cross-section of the compression body 100. In which the outer contour of the radial cross section of the reservoir 200 is generally circular, the outer contour of the radial cross section of the compression body 100 is circular, and the volume of the reservoir 200 is the product of the area of its radial cross section and its height. It can be understood that the accumulator 200 needs to ensure a certain volume to ensure a sufficient amount of stored liquid, and if only the height of the accumulator 200 is reduced, the volume of the accumulator 200 is reduced, which easily causes the liquid return phenomenon, and further causes the reliability of the compressor 10 to be reduced. Increasing the volume of the reservoir may further lower the center of gravity of the compressor 10, thereby improving the stability of the compressor 10.

Referring to fig. 10 to 12, in order to improve the sealing effect between the reservoir 200 and the compression body 100 in consideration of the high pressure environment inside the compression body 100, in a preferred embodiment, the upper end surface 201 of the reservoir 200 is provided with a fixing ring 230, and the inner side wall of the fixing ring 230 is matched with the outer side wall of the compression body 100. Typically, the retainer ring 230 is integrally formed with the reservoir 200. Therefore, through the arrangement of the fixing ring 230, two connection surfaces are formed between the compression main body 100 and the reservoir 200, so that the sealing effect between the reservoir 200 and the compression main body 100 is improved. Preferably, the outer sidewall of the compression body 100 abuts the inner sidewall of the fixing ring 230.

That is, the compression body 100 protrudes into the sink groove 203. Thus, by the arrangement of the sinking groove 203, two connection surfaces are formed between the compression main body 100 and the reservoir 200, thereby improving the sealing effect between the reservoir 200 and the compression main body 100. Preferably, the outer side wall of the compression body 100 abuts the inner side wall of the sink groove 203.
