Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a horizontal liquid storage device and a compressor. Background Art

[0002] The working principle of the rotary compressor is to use the slider to divide the cylinder into an intake chamber and an exhaust chamber. When the motor is powered on, the stator coil generates an electromagnetic field, and the rotor cuts the magnetic lines to generate power to drive the crankshaft of the pump body to rotate, causing the piston to rotate in the cylinder to compress the refrigerant. Under the action of the crankshaft, the volume of the intake and exhaust chambers is constantly changed, sucking in low-temperature and low-pressure gaseous refrigerant, compressing it into high-temperature and high-pressure gaseous refrigerant and then discharging it from the pump body, and the cycle continues.

[0003] In a horizontal compressor, since the liquid accumulator is placed horizontally, the liquid refrigerant in the accumulator has a small sedimentation space and a short sedimentation distance after suction, resulting in the undesirable phenomenon of liquid return in the exhaust pipe. In addition, the exhaust pipe used to connect the liquid accumulator and the compressor body usually has a flat-end design at its port, and the flat-end exhaust pipe is inserted into a deeper position inside the liquid accumulator to solve the liquid return problem in the exhaust pipe. However, the resistance along the way for the gaseous refrigerant will increase, thereby reducing the suction and exhaust efficiency of the accumulator, resulting in reduced compression efficiency. Utility Model Content

[0004] Based on this, the purpose of the utility model is to overcome the deficiencies of the prior art and provide a horizontal liquid reservoir, which can effectively reduce the liquid return problem of the liquid reservoir in the compressor, while being able to improve the compression efficiency and reduce the fluid noise.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A horizontal liquid reservoir comprises a horizontally placed liquid reservoir shell, an air inlet pipe and an exhaust pipe, a baffle is provided on the inner top of the liquid reservoir shell, and the bottom of the baffle is spaced apart from the bottom of the liquid reservoir shell so that the baffle defines a connected air inlet cavity and an exhaust cavity inside the liquid reservoir shell, the air inlet pipe is connected at one end of the liquid reservoir shell, one end of the exhaust pipe passes through the bottom of the liquid reservoir shell and extends vertically into the exhaust cavity, and an oblique cut is provided at the end of the exhaust pipe extending into the exhaust cavity, the upper end of the oblique cut is spaced apart from the top of the liquid reservoir shell, and the lower end of the oblique cut is located higher than the bottom of the baffle.

These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention.

[0030] In the description of the present invention, it needs to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "left", "right", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] See also Figures 1 to 6 ; The present embodiment provides a horizontal liquid reservoir, comprising a horizontally placed liquid reservoir shell 10, an air inlet pipe 14, and an exhaust pipe 20. A baffle 11 is provided at the inner top of the liquid reservoir shell 10, and the bottom of the baffle 11 is spaced apart from the bottom of the liquid reservoir shell 10, so that the baffle 11 defines a connected air inlet chamber 12 and an exhaust chamber 13 inside the liquid reservoir shell 10. The air inlet pipe 14 is connected to one end of the liquid reservoir shell 10, and one end of the exhaust pipe 20 passes through the bottom of the liquid reservoir shell 10 and vertically extends into the exhaust chamber 13. An oblique cut 21 is provided at the end of the exhaust pipe 20 extending into the exhaust chamber 13, and the upper end of the oblique cut 21 is spaced apart from the top of the liquid reservoir shell 10, and the lower end of the oblique cut 21 is higher than the bottom position of the baffle 11.

[0032] It can be understood that the horizontal liquid reservoir of this embodiment is placed in such a way that its axial direction is parallel to the horizontal plane, and the air intake direction of the air intake pipe 14 is consistent with the axial direction of the horizontal liquid reservoir. In this embodiment, the liquid reservoir housing 10 can be composed of a cylinder, a left cover, and a right cover, wherein the cylinder is a cylindrical structure with openings at both ends, the left cover and the right cover are respectively sealed at the openings at both ends of the cylinder, the air intake pipe 14 is arranged on the right cover, and the air intake pipe 14 is connected to the air intake chamber 12. In addition, a filter member 15 is arranged in the air intake chamber 12, and the filter member 15 is located between the right cover and the baffle 11, and a vent is provided on the filter member 15.

[0033] Therefore, the refrigerant of this embodiment enters the air intake chamber 12 from the air intake pipe 14, first passes through the filter element 15 and the baffle 11, and then a part of the liquid phase refrigerant in the air flow settles from the baffle 11 to the bottom of the liquid storage tank shell 10, and then the air flow passes through the bottom of the baffle 11 and enters the exhaust chamber 13.

[0034] Optionally, the upper end surface of the baffle 11 of this embodiment is an arc-shaped surface structure, and the upper end surface of the baffle 11 is connected to the inner top of the reservoir housing 10, and the bottom of the baffle 11 is a horizontal surface structure. Among them, the height difference formed between the upper end of the oblique cut 21 and the bottom of the baffle 11 is D, and D satisfies the relationship: 27mm≤D≤29mm; in addition, the height difference formed between the upper end of the oblique cut 21 and the top of the reservoir housing 10 is d, and d satisfies the relationship: 1mm≤d≤3mm. In this embodiment, D is one of 27mm, 28mm, and 29mm, and d is one of 1mm, 2mm, and 3mm.

[0035] The bevel cut can be arranged directly opposite to the baffle, or the bevel cut can also be arranged opposite to the baffle. In the present embodiment, the bevel cut is arranged opposite to the baffle. That is to say, the bevel cut 21 of the present embodiment is arranged opposite to the baffle 11, and its lower end is located higher than the bottom position of the baffle 11, and its upper end is located slightly lower than the top position of the reservoir housing 10, so that the insertion depth of one end of the exhaust pipe 20 extending into the interior of the reservoir housing 10 is deep enough, and at the same time, the bevel cut 21 is spaced from the top of the reservoir housing 10 to prevent the two from contacting and causing vibration noise. In this way, the oblique cut 21 of the present embodiment is facing away from the airflow direction, and the insertion depth of the end of the exhaust pipe 20 provided with the oblique cut 21 is higher, so that the refrigerant flowing from the air inlet chamber 12 into the exhaust chamber 13 first contacts the tube wall of the exhaust pipe 20, thereby blocking most of the liquid refrigerant and causing it to settle inside the liquid reservoir shell 10. At the same time, the pipe mouth of the exhaust pipe 20 adopts the design of the oblique cut 21, which can effectively ensure the exhaust efficiency of the liquid reservoir and effectively reduce the liquid refrigerant entering the exhaust pipe 20, thereby solving the liquid return problem of the liquid reservoir in the prior art.

[0036] On the other hand, the angle of inclination formed by the oblique cut 21 of the present embodiment and the horizontal plane is A, and A satisfies the relationship: 20°≤A≤50°. In the present embodiment, A can be one of 20°, 30°, 35°, 40°, and 50°; for example, when A is 50°, the area of ​​the oblique cut 21 is more appropriate, which can ensure the sedimentation effect of the liquid refrigerant to reduce the return liquid, and also ensure the circulation of the gas refrigerant to reduce the resistance along the way in the liquid storage tank, ensure the gas refrigerant flux, and thus improve the efficiency of the compressor.

[0037] Compared with the prior art, the present embodiment provides a baffle 11 at the inner top of the reservoir housing 10, and makes the baffle 11 perpendicular to the axis of the reservoir housing 10, so that the baffle 11 defines an air inlet chamber 12 and an air exhaust chamber 13 inside the reservoir housing 10, and the air flow direction inside the reservoir housing 10 flows from the air inlet chamber 12 into the air exhaust chamber 13 along the axial direction of the reservoir housing 10; further, the present invention increases the insertion depth of one end of the exhaust pipe 20 extending into the reservoir housing 10, and provides an oblique cut 21 at the end of the pipe extending into the interior of the reservoir housing 10, and at the same time, the oblique cut 21 is arranged opposite to the baffle 11, that is, the oblique cut 21 is opposite to the baffle 11. The direction of air flow, and the insertion depth of one end of the exhaust pipe 20 with the oblique cut 21 is higher, so that the refrigerant flowing from the air inlet chamber 12 into the exhaust chamber 13 first contacts the pipe wall of the exhaust pipe 20, and thereby blocks most of the liquid refrigerant, causing it to settle inside the liquid reservoir shell 10. At the same time, the pipe mouth of the exhaust pipe 20 adopts the design of the oblique cut 21, which can effectively ensure the exhaust efficiency of the liquid reservoir, and at the same time can effectively reduce the liquid refrigerant from entering the exhaust pipe 20, so as to solve the liquid return problem of the liquid reservoir in the prior art; in addition, the upper end of the oblique cut 21 of the exhaust pipe 20 is spaced from the top of the liquid reservoir shell 10, so as to avoid the exhaust pipe 20 from contacting the wall of the liquid reservoir shell 10 and generating vibration noise.

[0038] In addition, the present embodiment further provides a compressor, which includes any of the above-mentioned horizontal liquid accumulators, and also includes a compressor body, and one end of the exhaust pipe 20 extending outside the liquid accumulator housing 10 is connected to the compressor body. The compressor of the present embodiment can effectively reduce the liquid return problem of the liquid accumulator in the compressor by improving the structure of the exhaust pipe 20, and can also improve the compression efficiency and reduce the fluid noise.

[0039] In some other embodiments, the number of the exhaust pipes 20 can also be set to two, and the two exhaust pipes 20 are arranged side by side and spaced along the axial direction of the liquid reservoir housing 10 at one end respectively extending into the exhaust cavity 13, and the oblique cuts 21 on the two exhaust pipes 20 are arranged opposite to each other or in the same direction. It can be understood that by adding an exhaust pipe 20, the circulation of the gas refrigerant can be further improved, thereby improving the efficiency of the compressor.

[0040] like Figure 4 As shown, in this embodiment, the oblique cuts 21 on the two exhaust pipes 20 are arranged in the same direction, and the oblique cuts 21 on the two exhaust pipes 20 are arranged with their backs facing the baffle 11 .

[0041] like Figure 7 As shown, in this embodiment, the oblique cuts 21 on the two exhaust pipes 20 are arranged in the same direction, and the oblique cuts 21 on the two exhaust pipes 20 are arranged directly opposite to the baffle 11.

[0042] like Figure 8 As shown, in this embodiment, the oblique cuts 21 on the two exhaust pipes 20 are arranged opposite to each other, and the oblique cut 21 on the exhaust pipe 20 close to the baffle 11 is arranged with its back facing the baffle 11.

[0043] like Fig. 9 As shown, in this embodiment, the oblique cuts 21 on the two exhaust pipes 20 are arranged back to back, and the oblique cut 21 on the exhaust pipe 20 close to the baffle 11 is arranged directly opposite to the baffle 11.

[0044] It can be understood that, through the arrangement of the two exhaust pipes 20 described in the above embodiment, those skilled in the art can also make several modifications and improvements to the arrangement of the two exhaust pipes 20, and are not limited to the above-mentioned arrangements.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model horizontal liquid storage device and compressor. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
