Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a compressor and an air conditioner having the same. Background Art

[0002] The scroll compressor continuously and stably supplies lubricating oil to each friction pair of the compressor through a gear oil pump. Adequate oil volume and circulation of lubricating oil inside the shell can prevent wear of parts. At the same time, the flowing oil can take away friction heat, effectively improving the overall reliability of the compressor. With the development of high efficiency and high speed of scroll compressors, a series of reliability problems such as friction and wear have begun to appear in the internal parts of the compressor. The reasons include: 1. Due to the high oil discharge rate of the compressor, the high-speed fluid brings the lubricating oil into the system, and the oil cannot be returned in time, causing the compressor to be empty of oil; 2. Under high-frequency working conditions, the oil pumping amount of the oil pump increases in the same unit time. Due to the existence of the viscosity of the lubricating oil, the return oil speed and the pumping oil speed do not change in equal amounts. If there is a problem with the design of the oil return oil circuit, it is very easy to cause the lubricating oil to concentrate in the upper chamber, causing the bottom oil pool to be empty of oil.

[0033] Combination Figures 1 to 6 As shown, according to a specific embodiment of the present application, a compressor is provided.

[0034] Specifically, Figure 1 and Figure 2 As shown, the compressor includes a housing 3, a pump assembly and an oil-gas guide 10. The pump assembly is arranged in the housing 3, and the pump assembly has a first exhaust passage 9. The oil-gas guide 10 is connected to the housing 3. A second exhaust passage 11 and an oil return passage 6 are formed between the outer surface of the oil-gas guide 10 and the inner wall surface of the housing 3, the inlet end of the second exhaust passage 11 is connected to the first exhaust passage 9, the outlet end of the second exhaust passage 11 is connected to the outlet end of the oil return passage 6, and the inlet end of the oil return passage 6 is connected to the cavity in which the pump assembly is arranged.

[0035] In this embodiment, an oil and gas guide portion is provided so that a second exhaust passage 11 and an oil return passage 6 are formed between the oil and gas guide portion and the shell, and the second exhaust passage 11 is arranged to be connected to the oil return passage 6. This can accelerate the rapid return of the lubricating oil on one side of the pump body assembly to the oil pool through the oil return passage 6, effectively reducing the oil discharge rate of the compressor, stabilizing the oil level in the oil pool inside the compressor, and ensuring that the compressor operates more reliably and stably.

[0036] By providing an oil and gas guide portion, a second exhaust passage 11 and an oil return passage 6 are formed between the oil and gas guide portion and the shell, and the second exhaust passage 11 is arranged to be connected to the oil return passage 6, which can accelerate the lubricating oil on one side of the pump body assembly to quickly return to the oil pool through the oil return passage 6, effectively reducing the oil discharge rate of the compressor, stabilizing the oil level in the oil pool inside the compressor, and ensuring that the compressor operates more reliably and stably.

[0037] The pump body assembly includes a bracket 4, a fixed scroll 7 and a movable scroll 14. The bracket 4 is connected to the housing 3, and the oil and gas guide 10 is located below the bracket 4. The fixed scroll 7 is connected to the housing 3, and the tooth portion of the fixed scroll 7 is arranged toward the side of the bracket 4. The movable scroll 14 is arranged between the bracket 4 and the fixed scroll 7, and the tooth portion of the movable scroll 14 is arranged in meshing with the tooth portion of the fixed scroll 7, and the tooth portion of the fixed scroll 7 cooperates with the tooth portion of the movable scroll 14 to form a working chamber, and a first exhaust channel 9 connected to the working chamber is provided on the bracket 4, and an oil discharge channel is provided on the bracket 4, and the inlet end of the oil return channel 6 is connected to the oil discharge channel. The oil discharge channel is connected to the center hole of the crankshaft inside the housing, so that the crankshaft can conveniently transport the lubricating oil inside the oil pool to the bracket through the crankshaft to lubricate other components, and it is also convenient to timely transport the lubricating oil to the oil pool of the compressor through the oil return channel 6. The oil and gas guide part 10 is a sheet metal part, and the sheet metal part is extended along the circumference of the housing 3. Such an arrangement can improve the reliability of the compressor.

[0038] Furthermore, the oil drain channel is arranged in the radial direction, and the end of the oil drain channel is formed between the inner wall surface of the part of the housing 3 and the bracket 4, and the inlet end of the oil return channel 6 is connected to the end of the oil drain channel. This arrangement enables the oil return channel 6 to be connected to the oil drain channel at the inner wall of the housing, and this arrangement can reduce the processing difficulty of the oil drain channel and improve the oil return efficiency of the oil return channel 6.

[0039] like Figure 1 As shown, the compressor includes an oil guide plate 5. The oil guide plate 5 is arranged in the housing 3, one end of the oil guide plate 5 extends into the bracket 4, and the other end of the oil guide plate 5 extends into the oil return channel 6. This arrangement can further improve the oil return efficiency of the oil return channel 6.

[0040] like Figure 2 As shown, an exhaust port is provided on the side wall of the housing 3, the exhaust port is communicated with the second exhaust channel 11, and an exhaust pipe 13 is provided at the exhaust port. This arrangement can discharge the gas compressed by the pump assembly to the outside of the compressor housing.

[0041] The oil and gas guide portion 10 and the inner wall of the housing 3 form a communication channel 18. The first end of the communication channel 18 is connected to the outlet end of the second exhaust channel 11, and the second end of the communication channel 18 is connected to the outlet end of the oil return channel 6. The communication channel 18 extends along the circumference of the housing 3. This arrangement allows the compressor to be operated in the second exhaust channel 11, and the exhaust effect of the exhaust pipe 13 causes the pressure on one side of the second exhaust channel 11 to be lower than the pressure on the side of the oil return channel 6, so that a pressure difference is formed between the second exhaust channel 11 and the oil return channel 6, thereby increasing the amount of lubricating oil when the compressor is operated at high frequency, and the refrigerant flow rate of the second exhaust channel 11 also increases. According to Bernoulli's principle, the flow rate on the exhaust side is fast and the pressure is low. At this time, a high and low pressure difference is established between the second exhaust channel 11 and the oil return channel 6. The higher the frequency, the greater the pressure difference, which causes the lubricating oil to be diverted, forcing the lubricating oil to flow from the oil return channel 6 to the second exhaust channel 11. As the high-speed refrigerant flows to the lower chamber of the shell, the lubricating oil refluxes. The pressure difference on both sides avoids the phenomenon of high-frequency lubricating oil being blocked in the oil return sheet metal, and it will not overflow from the sheet metal and be carried out of the compressor by the high-speed fluid, thereby solving the problem of high-frequency oil return in the scroll compressor.

[0042] like Figure 1 As shown, there are multiple first exhaust channels 9, and the outlet ends of the multiple first exhaust channels 9 are all connected to the inlet end of the second exhaust channel 11. This arrangement can improve the exhaust efficiency of the pump body assembly.

[0043] Furthermore, the compressor further includes a motor stator 16. The motor stator 16 is disposed in the housing 3 and below the oil and gas guide portion 10. The outer edge of the motor stator 16 is provided with a plurality of trimming structures, each trimming structure and the inner wall of the housing 3 are surrounded to form a cooling channel, at least one of the plurality of cooling channels is connected to the second exhaust channel 11, and at least one of the plurality of cooling channels is connected to the oil return channel 6. Such a configuration can improve the efficiency of cooling the motor.

[0044] like Figure 4 and Figure 5As shown, the sheet metal part has a first recess 101, a second recess 102, a third recess 103 and a fourth recess 104. The first recess 101 and the shell 3 are arranged to form the inlet end of the second exhaust channel 11, the second recess 102 and the shell 3 are arranged to form the outlet end of the second exhaust channel 11, the third recess 103 and the shell 3 are arranged to form the return oil channel 6, and the fourth recess 104 and the shell 3 are arranged to form the connecting channel 18. This arrangement makes the structure of the sheet metal part simple and reliable. Among them, the area of ​​the first recess 101 is larger than the area of ​​the second recess 102. The second recess 102 and the third recess 103 are arranged in the vertical direction.

[0045] like Figure 6 As shown, there are two fourth recesses 104, and the two fourth recesses 104 cooperate with the housing to form two communicating channels 18. This arrangement can further improve the oil return efficiency of the oil return channel 6.

[0046] The compressor in the above embodiment may also be used in the technical field of air-conditioning equipment. That is, according to another aspect of the present invention, an air conditioner is provided, comprising a compressor, and the compressor is the compressor in the above embodiment.

[0047] Specifically, the second exhaust channel on the sheet metal has two outlets, one for discharging the refrigerant out of the shell, and the other for passing the refrigerant to the stator side of the motor to reduce the temperature of the motor. The outlet end of the oil return channel leads to the stator cut edge for oil return.

[0048] like Figure 1 and Figure 2 As shown, the scroll compressor is mainly composed of an air intake pipe 1, a compressor upper cover 2, a motor stator 16, a fixed scroll 7, a movable scroll 14, a crankshaft 8, sheet metal parts, a foot pad 12, a gear oil pump 15, a muffler 17, etc. The motor stator 16 and the bracket 4 are fixed on the housing 3. The movable scroll 14 and the fixed scroll 7 are installed on the upper bracket support plate with a phase angle difference of 180 degrees. The movable scroll 14 moves under the drive of the crankshaft 8 and meshes with the fixed scroll 7 to form a series of crescent-shaped closed working chambers that are isolated from each other and have continuously changing volumes. When the compressor is running, the rotor drives the crankshaft 8 to rotate, and the crank section of the crankshaft 8 is installed with an eccentric sleeve with radial flexibility. The eccentric sleeve drives the movable scroll 14 to move. Under the anti-rotation restriction of the cross slip ring, the movable scroll 14 moves in a fixed radius around the center of the crankshaft. The refrigerant entering from outside the compressor is sucked into the crescent-shaped working chamber formed by the orbiting scroll 14 and the fixed scroll 7 , and is discharged from the exhaust hole of the fixed scroll 7 after being compressed.

[0049] Among them, the gas circuit structure includes the refrigerant discharged from the exhaust port of the fixed scroll plate 7 flowing through the muffler 17, the first exhaust channel 9 on the bracket, and flowing through the sheet metal, which is fixed on the shell 3. After passing through the sheet metal, a small part of the refrigerant is used to cool the motor stator 16, and a large part of the gas is discharged to the compressor along the left branch. The oil circuit structure is to pump oil to the crankshaft 8 through the gear oil pump 15, and the crankshaft 8 lubricates each sliding bearing through each crankshaft oil hole. After the pump is stored in the oil measuring cavity under the movable scroll plate 14, it flows through the left oil discharge hole, flows through the sheet metal under the guidance of the oil guide plate 5, and flows back to the oil pool at the bottom of the compressor along the cut edge of the motor stator 16.

[0050] like Figure 4 As shown in the figure, when the compressor is running at low frequency, the refrigerant and lubricating oil in the sheet metal parts go through their own paths and do not interfere with each other. Figure 5 As shown, when the compressor is running at medium and high frequencies, the amount of lubricating oil input by the gear oil pump 15 increases, resulting in a large amount of lubricating oil being stored in the oil return oil circuit. At this time, the refrigerant flow rate flowing through the second exhaust channel also increases due to the high-frequency operation. According to the Bernoulli principle, the pressure is low where the flow rate is fast, and the gas path flowing through the stator cut edge produces a low-pressure area, forming a pressure difference with the high-pressure side of the oil return channel. This pressure difference increases step by step with the increase of the compressor operating frequency, and plays a role of "oil absorption" for the lubricating oil stored in the oil return channel. The lubricating oil in the connecting channel is brought to the cut edge of the motor stator 16 by the high-speed downward lubricating oil until it flows back to the oil pool, reducing the oil discharge rate of the scroll compressor. This oil absorption capacity is gradually enhanced as the frequency increases and the amount of pump oil increases, solving the problem of high-frequency oil return difficulty of the scroll compressor.

[0051] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
