The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
A horizontal compressor 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 3, wherein the horizontal compressor 100 can be used in a refrigeration device (e.g., an air conditioner, an ice chest, etc.).
As shown in fig. 1, the horizontal compressor 100 according to the embodiment of the present invention may include: a housing 1, a compression mechanism section 2, and a motor section 3.
The casing 1 may be provided with an exhaust pipe 7, and the compression mechanism 2 may be provided in the casing 1. The compression mechanism part 2 may be fitted with an inner wall of the casing 1 to partition the casing 1 into a first cavity 1a and a second cavity 1b, the exhaust pipe 7 may be communicated with the first cavity 1a, and the motor part 3 may be provided in the second cavity 1 b. For example, as shown in fig. 1, the first cavity 1a and the second cavity 1b may be disposed at an interval in the left-right direction. The first cavity 1a is located on the right side of the compression mechanism 2, and the second cavity 1b is located on the left side of the compression mechanism 2. When the horizontal compressor 100 works, the compression mechanism 2 can compress the refrigerant, a part of compressed refrigerant gas can be directly discharged through the exhaust pipe 7, another part of compressed refrigerant gas can enter the second cavity 1b to cool the motor component 3, and then the refrigerant can enter the first cavity 1a and is discharged through the exhaust pipe 7.
As shown in fig. 1, the compression mechanism part 2 may include a cylinder 21, a main bearing 22, a sub bearing 23, and a crankshaft 24, the main bearing 22 and the sub bearing 23 may be respectively disposed at opposite sides of the cylinder 21, the main bearing 22, the sub bearing 23, and the cylinder 21 may collectively define a cylinder chamber, and a refrigerant may be compressed in the cylinder chamber. Rotor 32 of motor assembly 3 may cooperate with crankshaft 24 to drive crankshaft 24 in rotation. Specifically, the compression mechanism section 2 may further include a piston, and the piston may be provided in the cylinder 21. One end of the crankshaft 24 may be matched with the rotor 32 to be driven by the rotor 32 to rotate, and the other end of the crankshaft 24 may be matched with the piston to drive the piston to move in the cylinder cavity, so as to compress the refrigerant in the cylinder cavity.
As shown in fig. 2 to 3, an oil passage 2a for communicating the first cavity 1a and the second cavity 1b may be provided in the compression mechanism 2, the oil passage 2a may include an oil passage 221 provided in the main bearing 22, the main bearing 22 may be provided with an air outlet 223 for discharging compressed refrigerant in the cylinder 21 to the second cavity 1b, the main bearing 22 may be provided with an air vent 222 penetrating therethrough in a thickness direction (a left-right direction as shown in fig. 1), and the air vent 222 may be provided above the oil passage 221.
Specifically, an oil sump 1c may be provided in the housing 1, lubricating oil may be stored in the oil sump 1c, and the lubricating oil in the oil sump 1c may flow through the oil passage 2 a. When the horizontal compressor 100 works, part of the refrigerant compressed in the cylinder cavity can be discharged into the second cavity 1b through the air outlet 223, the refrigerant entering the second cavity 1b can cool the motor part 3, then the refrigerant can enter the first cavity 1a through the vent hole 222, and finally the refrigerant can be discharged through the exhaust pipe 7. When the refrigerant enters the second cavity 1b, the pressure in the second cavity 1b is increased, and the lubricating oil in the second cavity 1b can enter the first cavity 1a through the oil hole 221 and the oil passage 2a under the action of the pressure. The lubricating oil in the oil passage 2a can also enter the compression mechanism section 2 to lubricate the compression mechanism section 2, whereby the operation of the horizontal compressor 100 can be made smoother.
Wherein the opening area S of the vent hole 2221Opening area S with the air outlet 2232The relation can be satisfied: 1 < S1/S2Is less than 10. It is understood that when the opening area S of the vent hole 222 is larger1Smaller than the opening area S of the air outlet 2232When the refrigerant enters the first cavity 1a through the vent hole 222 after cooling the motor part 3, the opening area of the vent hole 222 is too small, so that the circulation pressure of the refrigerant is increased, and the flow rate of the refrigerant is increased. According to the energy conversion theorem, the heat energy of the refrigerant is converted into the kinetic energy, so that the heat of the refrigerant is reduced, the heat exchange efficiency of the refrigerant is reduced, and the energy efficiency of the horizontal compressor 100 is further reduced. When the opening area S of the vent hole 2221More than ten times the opening area S of the air outlet 2232In the meantime, the opening area of the vent hole 222 is too large, and the refrigerant entering the second cavity 1b quickly enters the first cavity 1a through the vent hole 222, so that the circulation time of the refrigerant in the first cavity 1a is shortened, and the cooling effect of the motor part 3 is reduced.
When 1 < S1/S2When the temperature is less than 10 ℃, the refrigerant can circulate in the second cavity 1b, and the cooling time of the refrigerant entering the second cavity 1b to the motor part 3 can be prolonged, so that the motor part 3 can be sufficiently cooled, and the normal operation of the motor part 3 is ensured. When the refrigerant flows through the second cavity 1b, the lubricant in the refrigerant may adhere to the motor part 3 and the inner peripheral wall of the second cavity 1b, thereby reducing the oil discharge amount of the horizontal compressor 100. Moreover, since the opening area of the vent hole 222 is reasonably set, the heat of the refrigerant is not sacrificed when the refrigerant passes through the vent hole 222, so that the energy efficiency of the horizontal compressor 100 can be ensured.
Therefore, through the arrangement, the oil through hole 221 and the air through hole 222 are formed in the main bearing 22, the circulation requirement of lubricating oil and the cooling requirement of the motor part 3 can be met simultaneously, an oil guide cavity in the related technology is not required to be formed, the structure of the horizontal compressor 100 can be more compact, the height of a hot jacket of the rotor 32 can be reduced, and the running stability of the horizontal compressor 100 can be improved.
Optionally, main bearing 22 can be fixed on the internal perisporium of shell 1 through welded connection's mode, and cylinder 21 also can be fixed on the internal perisporium of shell 1 through welded connection's mode, can select the setting according to the assembly demand of reality, the utility model discloses do not do specific restriction to this.
According to the embodiment of the present invention, the horizontal compressor 100 has the oil hole 221 and the air hole 222 on the main bearing 22, and the opening area S of the air hole 2221Opening area S with the air outlet 2232Satisfy the relation: 1 < S1/S2< 10, therefore, not only the cooling effect of the motor part 3 can be improved, but also the structure of the horizontal compressor 100 can be more compact, the height of the thermal jacket of the rotor 32 can be reduced, and the operation stability of the horizontal compressor 100 can be improved.
According to the utility model discloses a some embodiments, the open area of logical oilhole 221 can be greater than the open area of air vent 222, can make the fuel feeding in horizontal compressor 100 more smooth and easy from this, can promote horizontal compressor 100's lubricated effect. It can be understood that when the opening area of the vent hole 222 is smaller than that of the oil hole 221, the air pressure in the second chamber 1b is increased when the refrigerant is discharged into the second chamber 1b through the air outlet 223. Under the action of the air pressure, the lubricating oil in the second cavity 1b can enter the oil passage 2a through the oil through hole 221. However, since the opening area of the oil through hole 221 is too small, the flow resistance of the lubricating oil is increased, and the oil through hole 221 is easily blocked, thereby affecting the normal flow of the lubricating oil and further affecting the lubricating effect of the horizontal compressor 100. When the opening area of the oil hole 221 is larger than the opening area of the air vent 222, the circulation space of the oil hole 221 can be increased, the lubricating oil in the second cavity 1b can smoothly enter the first cavity 1a, and the lubricating oil can smoothly circulate, so that the lubricating effect of the horizontal compressor 100 can be improved.
As shown in fig. 1, according to some embodiments of the present invention, the rotor 32 may be provided with a diversion hole 321 running through the rotor in the axial direction (the left and right directions shown in fig. 1), from which the heat generated by the rotor 32 during operation can be dissipated through the diversion hole 321, and the refrigerant entering the second cavity 1b simultaneously circulates in the gap between the stator 31 and the rotor 32 and the diversion hole 321, so as to improve the cooling efficiency of the motor component 3, greatly reduce the working temperature of the motor component 3, and further ensure the normal operation of the motor component 3.
As shown in fig. 1, in some embodiments of the present invention, the flow guide holes 321 may be multiple, and the plurality of flow guide holes 321 may be distributed at intervals in the circumferential direction of the rotor 32, so that the refrigerant entering the second cavity 1b may flow through the plurality of flow guide holes 321 at the same time, and the contact area between the refrigerant and the rotor 32 may be increased, thereby further improving the cooling efficiency of the motor component 3.
As shown in fig. 1, according to some embodiments of the present invention, a lubricating oil path 241 running through the crankshaft 24 along its axial direction (left and right directions as shown in fig. 1) may be provided in the crankshaft 24, the horizontal compressor 100 may further include an oiling component 4 and a rotor fan 5, the oiling component 4 may be provided in the first cavity 1a, an oil guiding flow path 4a may be defined in the oiling component 4, one end of the oil guiding flow path 4a may be communicated with the lubricating oil path 241, the other end of the oil guiding flow path 4a may extend into the lubricating oil in the first cavity 1a, and the rotor fan 5 may be provided on the end surface (left end as shown in fig. 1) of the rotor 32 far away from the compression mechanism portion 2.
Specifically, when the horizontal compressor 100 operates, the rotor 32 may rotate to rotate the rotor fan 5, so that a negative pressure may be formed in the second chamber 1b, and the pressure at the left end of the lubricating oil path 241 is lower than the pressure at the right end of the lubricating oil path 241. Under the action of the negative pressure, the lubricating oil in the first cavity 1a may enter the lubricating oil path 241 through the oil guide path 4a to circulate, the lubricating oil in the lubricating oil path 241 may sufficiently lubricate the compression mechanism portion 2 when circulating, and then the lubricating oil may enter the oil sump 1c in the second cavity 1b through the leftmost end of the lubricating oil path 241. Since the refrigerant compressed in the cylinder chamber can be discharged into the second chamber 1b through the outlet 223, the pressure in the second chamber 1b is increased, and the lubricating oil in the second chamber 1b can enter the first chamber 1a through the oil hole 221 and the oil passage 2a under the action of the pressure.
Therefore, through the above arrangement, by providing the lubricating oil path 241 in the crankshaft 24 and defining the oil guide flow path 4a in the oil feeding part 4, the rotor fan 5 can cooperate with the oil feeding part 4 to realize the circulation of the lubricating oil in the horizontal compressor 100, so that the lubricating effect of the horizontal compressor 100 can be improved, and the operation of the horizontal compressor 100 can be smoother.
As shown in fig. 1, in some embodiments of the present invention, the upper oil component 4 may include an outer cover 41 and an oil inlet pipe 42, the outer cover 41 may be sleeved on the auxiliary bearing 23, the outer cover 41 may define a cavity 41a communicating with the lubricating oil path 241 with the auxiliary bearing 23, and the oil inlet pipe 42 may be disposed on the outer cover 41 to guide the lubricating oil in the first cavity 1a to the cavity 41 a. Specifically, an oil inlet space 42a may be provided in the oil inlet pipe 42, and the oil inlet space 42a communicates with the cavity 41a to define the oil guide flow path 4a together. When the horizontal compressor 100 is operated, the lubricating oil in the oil sump 1c of the first cavity 1a may be pressed into the oil inlet pipe 42 by pressure, and then the lubricating oil may sequentially flow to the cavity 41a and the lubricating oil path 241, whereby the lubricating oil in the first cavity 1a may be guided into the lubricating oil path 241. Through the above arrangement, the structural design of the oiling member 4 can be made simpler. Moreover, since the oil inlet pipe 42 may extend downward, when the level of the lubricating oil in the first cavity 1a is lower than the inlet height of the oil guide flow path 4a, the lubricating oil in the first cavity 1a may still smoothly enter the lubricating oil path 241 through the upper oil member 4, so that the lubricating effect of the horizontal compressor 100 may be ensured.
As shown in fig. 1, according to some embodiments of the present invention, the horizontal compressor 100 may further include a muffler 6, the muffler 6 may be disposed on one side (left side as shown in fig. 1) of the main bearing 22 close to the motor component 3, the muffler 6 may be matched with the main bearing 22 to define a muffling chamber, the gas outlet 223 may be communicated with the muffling chamber, and the muffler 6 may be provided with a muffling hole communicating the muffling chamber and the second chamber 1 b. Specifically, when the horizontal compressor 100 is in operation, the refrigerant discharged from the gas outlet 223 can enter the silencing cavity, and the volume of the refrigerant from the gas outlet 223 to the silencing cavity is rapidly expanded, so that the buffering and noise reduction effects can be achieved, and finally the refrigerant can enter the second cavity 1b through the silencing hole. Thus, the operation noise of the horizontal compressor 100 can be greatly reduced by the above arrangement.
The utility model discloses an in some embodiments, the bloop can be a plurality of and the open area of every bloop all is less than the open area of gas outlet 223, from this, when the refrigerant enters into second cavity 1b through the bloop, the bloop can increase the circulation pressure of refrigerant, can accelerate the circulation speed of refrigerant from this, can ensure that the refrigerant can circulate to motor element 3 about both ends, and then can promote motor element 3's cooling effect. Of course, it is understood that there may be one muffling hole, and the opening area of the muffling hole may be the same as the opening area of the air outlet 223. Wherein the opening area of the silencing hole can be S3Whereby, when 1 < S1/S3When the temperature is less than 10 ℃, the refrigerant can be ensured to smoothly circulate in the second cavity 1b, the motor part 3 can be sufficiently cooled, and the normal operation of the motor part 3 can be ensured.
According to some embodiments of the present invention, the oil hole 221 may include a plurality of oil through micro holes, and the plurality of oil through micro holes may be spaced apart from each other in the radial direction of the main bearing 22, that is, the plurality of oil through micro holes may be spaced apart from each other in the horizontal direction. From this, through above-mentioned setting, the lubricating oil in the oil bath 1c can circulate through a plurality of logical oil micropores simultaneously, can promote the circulation efficiency of lubricating oil.
According to some embodiments of the present invention, the vent hole 222 may include a plurality of spaced apart vent pores. It can be understood that, because the opening area of the ventilation micro-hole is smaller, the time of the refrigerant passing through the ventilation hole 222 can be prolonged, the circulation time of the refrigerant in the second cavity 1b can be prolonged, and the cooling effect of the motor component 3 can be further improved.

The first cavity 1a is located on the right side of the compression mechanism 2, and the second cavity 1b is located on the left side of the compression mechanism 2.
The compression mechanism part 2 includes a cylinder 21, a main bearing 22, a sub bearing 23, and a crankshaft 24, the main bearing 22 and the sub bearing 23 may be respectively disposed at two opposite sides of the cylinder 21, the main bearing 22, the sub bearing 23, and the cylinder 21 may collectively define a cylinder chamber, and a rotor 32 of the motor part 3 may cooperate with the crankshaft 24 to drive the crankshaft 24 to rotate. The rotor 32 may be provided with a guide hole 321 penetrating therethrough in an axial direction thereof, and the plurality of guide holes 321 may be spaced apart in a circumferential direction of the rotor 32.
A lubricating oil passage 241 is provided in the crankshaft 24 so as to penetrate therethrough in the axial direction (the left-right direction as viewed in fig. 1). The upper oil applying part 4 may be disposed in the first cavity 1a and the upper oil applying part 4 includes an outer cover 41 and an oil inlet pipe 42, the outer cover 41 may be sleeved on the secondary bearing 23, the outer cover 41 may define a cavity 41a communicating with the lubricating oil path 241 with the secondary bearing 23, the oil inlet pipe 42 may be disposed on the outer cover 41 to guide the lubricating oil in the first cavity 1a to the cavity 41a, and the rotor fan 5 may be disposed on an end surface (a left end as shown in fig. 1) of the rotor 32 away from the compression mechanism portion 2.

Opening area S of the vent hole 2221Opening area S with the air outlet 2232The relation can be satisfied: 1 < S1/S2＜10。
The muffler 6 may be provided on a side (left side as viewed in fig. 1) of the main bearing 22 close to the motor part 3, the muffler 6 may cooperate with the main bearing 22 to define a muffling chamber, the air outlet 223 communicates with the muffling chamber, and the muffler 6 may be provided with a muffling hole communicating the muffling chamber with the second cavity 1 b.
Specifically, when the horizontal compressor 100 works, the rotor 32 may drive the crankshaft 24 to rotate, and the right end of the crankshaft 24 cooperates with the piston to drive the piston to move in the cylinder cavity, so as to compress the refrigerant in the cylinder cavity. The refrigerant that the compression of cylinder chamber was accomplished can enter into the amortization intracavity through gas outlet 223, because the volume from gas outlet 223 to the amortization chamber refrigerant expands rapidly, can play the effect of making an uproar from this, then the refrigerant can enter into in the second cavity 1b through the amortization hole. The refrigerant entering the second cavity 1b can flow through the gap between the stator 31 and the rotor 32 and the plurality of flow guide holes 321 simultaneously, so that the cooling efficiency of the motor part 3 can be improved, the working temperature of the motor part 3 can be greatly reduced, and the normal operation of the motor part 3 can be ensured. Finally, the refrigerant may enter the first chamber 1a through the vent hole 222 and be discharged through the discharge pipe 7.

When the refrigerant is in the second cavity 1bDuring circulation, the lubricant in the refrigerant may adhere to the motor part 3 and the inner peripheral wall of the second cavity 1b, and thus the oil discharge amount of the horizontal compressor 100 may be reduced. Moreover, since the opening area of the vent hole 222 is reasonably set, the heat of the refrigerant is not sacrificed when the refrigerant passes through the vent hole 222, so that the energy efficiency of the horizontal compressor 100 can be ensured.
When the horizontal compressor 100 operates, the rotor 32 may rotate to drive the rotor fan 5 to rotate, so that a negative pressure may be formed in the second cavity 1b, and the pressure at the left end of the lubricating oil path 241 is smaller than the pressure at the right end of the lubricating oil path 241.
