Description

Technical Field

[0001] This invention belongs to the field of air conditioner technology, and relates to a compressor and an air conditioner using the same. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas and is the core component of a refrigeration system; while a liquid distributor is the core component of a compressor, which can temporarily store the portion of refrigerant that has not yet completely turned into gas at the end of the evaporator, preventing the liquid from affecting the performance of the compressor.

[0003] In existing compressors, the distributor is usually located on one side of the compressor, causing the compressor's center of gravity to deviate from the center of the compressor. During operation, the compressor's center of gravity is very likely to deviate significantly from the center of the compressor due to the unbalanced force of the compressor, which will aggravate the compressor vibration and cause the compressor noise to exceed the standard. Summary of the Invention

[0004] In view of this, the present invention provides a compressor and an air conditioner using the same, which solves the problem of excessive compressor noise caused by the location of the distributor in the conventional technology.

[0005] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides a compressor, which includes a housing and a pump assembly and a motor assembly installed within the housing. A liquid distribution assembly is provided at the upper part of the housing, and a liquid storage assembly communicating with the liquid distribution assembly is provided at the lower part of the housing.

[0006] In some embodiments, the liquid separation assembly includes a first pipe, a second pipe, a cylinder, and a first connecting pipe. The first pipe is located at one end of the cylinder for receiving refrigerant from the compressor, the second pipe is located at the other end of the cylinder for conveying gas separated from the refrigerant to the motor assembly, and the first connecting pipe is located on the side of the cylinder for conveying liquid separated from the refrigerant to the liquid storage assembly.

[0007] In some embodiments, the second conduit is disposed at the bottom of the cylinder and extends into the upper cavity of the motor assembly.

[0008] In some embodiments, the liquid dispensing assembly further includes a filtration unit disposed within the cylinder.

[0009] In some embodiments, the liquid storage assembly includes an upper cylinder, a lower cylinder, and a second connecting pipe. The upper and lower cylinders are fitted together to form a cavity for storing liquid. One end of the second connecting pipe is inserted into the upper cylinder, and the other end is connected to the first connecting pipe.

[0010] In some embodiments, the liquid reservoir is located below the housing and engages with the bottom of the housing.

[0011] In some embodiments, one side of the housing has an exhaust pipe communicating with the pump body assembly, and the liquid storage assembly is arranged in a ring outside the housing and above the exhaust pipe.

[0012] In some embodiments, the pump body assembly includes an upper flange, a crankshaft, a lower flange, and a cylinder, which are arranged sequentially from top to bottom, with the crankshaft passing through the upper flange, the lower flange, and the cylinder in sequence; the upper flange has a first vent hole, and the cylinder has a second vent hole, which communicate with the second vent hole so that gas can enter the cavity of the lower flange after passing through the first vent hole and the second vent hole.

[0013] In some embodiments, one end of the exhaust pipe communicates with the cavity of the lower flange, and the other end extends to the outside of the housing; and a sealing ring is provided on the portion of the exhaust pipe located inside the housing.

[0014] According to another aspect of this application, an embodiment of the present invention provides an air conditioner including the compressor described above.

[0015] Compared with the prior art, the compressor of the present invention has at least the following beneficial effects:

[0016] The compressor provided by this invention includes a housing and a pump assembly and a motor assembly installed inside the housing. A liquid separator is provided at the upper part of the housing, and a liquid storage assembly communicating with the liquid separator is provided at the lower part of the housing. With this structure, the refrigerant from the system first undergoes gas-liquid separation under the action of the liquid separator. The separated gas enters the pump assembly after passing through the gap between the motor assemblies, is compressed under the action of the pump assembly, and is then discharged from the compressor through the exhaust pipe and enters the system. The separated liquid enters the liquid storage assembly and is either discharged through the liquid storage assembly or enters the evaporator.

[0017] As can be seen from the above structure, the liquid distribution component in this invention is located at the top of the compressor, while the liquid storage component is located at a relatively lower position. Compared to the traditional single-sided liquid distributor, this arrangement prevents excessive changes in the compressor's center of gravity after adding the liquid storage component, resulting in more stable operation and reducing compressor vibration and noise caused by unbalanced forces. Furthermore, since the liquid distribution component is located at the top of the housing, the need for a top cover is eliminated compared to traditional compressors; the liquid distribution component directly functions as the top cover. Moreover, as can be seen from the gas transmission path in this invention, the refrigerant gas generated by the liquid distribution component directly enters the motor assembly, which can cool the motor and improve its efficiency.

[0018] The air conditioner provided by this invention is designed based on the above-mentioned compressor, and its beneficial effects are the same as those of the above-mentioned compressor, which will not be repeated here.

[0019] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] This embodiment provides a compressor, such as Figure 1-8 As shown, the compressor includes a housing 5 and a pump assembly 3 and a motor assembly 4 disposed within the housing 5. A liquid distribution assembly 1 is disposed on the upper part of the housing 5, and a liquid storage assembly 2 connected to the liquid distribution assembly 1 is disposed on the lower part of the housing 5.

[0036] Specifically, in this embodiment, the liquid distribution component 1 and the liquid storage component 2 form a traditional liquid distributor, which is used to temporarily store the portion of refrigerant that has not yet completely turned into gas at the end of the evaporator, so as to avoid the liquid affecting the performance of the compressor. In this embodiment, the pump body component 3 and the motor component 4 are arranged vertically, with the motor component 4 located above the pump body component 3. The housing 5 is the housing body 53 arranged on both sides of the pump body component 3 and the motor component 4, as well as the lower cover 54 arranged at the bottom of the compressor. The liquid distribution component 1 is located above the housing body 53, and the liquid storage component 2 is located at a relatively lower position on the housing body 53.

[0037] With this structure, the refrigerant from the system first undergoes gas-liquid separation under the action of the liquid separator 1. The separated gas first enters the upper cavity of the motor assembly 4, and then enters the pump body assembly 3 through the flow hole on the rotor of the motor assembly 4, the gap between the stator and rotor, the gap of the enameled wire, the stator tangent, etc. Under the action of the pump body assembly 3, it is compressed, and then discharged from the compressor through the exhaust pipe 51 and enters the system; while the separated liquid enters the liquid storage assembly 2, and is discharged through the liquid storage assembly 2 or enters the evaporator.

[0038] As can be seen from the above structure, in this embodiment, the liquid distribution component 1 is located at the top of the compressor, and the liquid storage component 2 is located at a relatively lower position on the compressor. Compared with the traditional single-sided liquid distributor, this arrangement ensures that the center of gravity of the compressor does not change too much after adding the liquid storage component, making the operation more stable and reducing compressor vibration and noise caused by unbalanced forces. In addition, since the liquid distribution component 1 is located at the top of the housing 5 in this embodiment, the use of a top cover is avoided compared with the traditional compressor, and the liquid distribution component 1 directly serves as the top cover. Furthermore, as can be seen from the gas transmission path in this embodiment, the gaseous refrigerant generated by the liquid distribution component 1 directly enters the motor assembly 4, which can cool the motor and improve the motor's efficiency.

[0039] In a specific embodiment, such as Figure 2 As shown, the liquid separation assembly 1 includes a first pipe 11, a second pipe 12, a cylinder 13, and a first connecting pipe 14. The first pipe 11 is opened at one end of the cylinder 13 to receive the refrigerant from the compressor. The second pipe 12 is opened at the other end of the cylinder 13 to transport the gas separated from the refrigerant to the motor assembly 4. The first connecting pipe 14 is opened on the side of the cylinder 13 to transport the liquid separated from the refrigerant to the liquid storage assembly 2.

[0040] More specifically, the cylinder 13 includes a first cylinder 131 located above and a second cylinder 132 located below. The inner diameter of the lower end of the first cylinder 131 is larger than the inner diameter of the upper end of the second cylinder 132, so that the lower end of the first cylinder 131 can cover the upper end of the second cylinder 132. Of course, the first cylinder 131 and the second cylinder 132 can also be fixed together in other ways, such as by direct welding. In order to ensure the firmness of the connection between the two, an additional fixing plate can be added to the outer ring of the connection.

[0041] The upper end of the first cylinder 131 has a first notch, into which a first pipe 11 is inserted. One end of the first pipe 11 can receive refrigerant from the air conditioning system, and the other end of the first pipe 11 guides the refrigerant into the cylinder 13. The lower end of the second cylinder 132 has a second notch, into which a second pipe 12 is inserted. One end of the second pipe 12 can receive the gas generated after gas-liquid separation by the liquid separator 1, and the other end of the second pipe 12 can transmit the gas to the upper cavity of the motor assembly 4. The second pipe 12 is a steel pipe. In addition, a third notch is provided on one side of the second cylinder 132, into which a first connecting pipe 14 is disposed. One end of the first connecting pipe 14 can receive the liquid generated after gas-liquid separation by the liquid separator 1, and the other end of the first connecting pipe 14 can transmit the liquid to the liquid storage assembly 2.

[0042] In a specific embodiment, the second pipe 12 is located at the bottom of the cylinder 13 and extends into the upper cavity of the motor assembly 4. More specifically, the second pipe 12 is located at the bottom of the second cylinder 132; thus, the compressor's suction pipe (i.e., the second pipe 12) is located at the lower part of the second cylinder 132, allowing the intake air to directly reach the upper cavity of the motor assembly 4, which can cool the motor assembly 4 and improve the motor's efficiency; the gas then flows through the flow hole on the motor rotor, the gap between the stator and rotor, the enameled wire gap, and the stator tangent to the lower cavity of the motor assembly 4, and then enters the pump body assembly 3 for compression.

[0043] In a specific embodiment, such as Figure 2 , Figure 5 as well as Figure 6 As shown, the liquid distribution assembly 1 also includes a filter unit 15, which is disposed inside the cylinder 13. More specifically, the filter unit 15 includes a filter screen and a support, with the filter screen fixed on the support. In this embodiment, the filter unit 15 is disposed inside the cylinder 13 of the liquid distribution assembly 1, separating the filter unit 15 from the liquid storage assembly 2. The liquid storage assembly 2 is disposed near the exhaust pipe 51 or at the bottom of the compressor, thereby lowering the center of gravity of the liquid distributor and consequently lowering the overall center of gravity of the compressor. This avoids excessive noise and vibration from the compressor due to a high center of gravity, which could affect the compressor's service life and customer satisfaction.

[0044] In a specific embodiment, such as Figure 3 and Figure 8 As shown, the liquid storage assembly 2 includes an upper cylinder 21, a lower cylinder 22, and a second connecting pipe 23. The upper cylinder 21 and the lower cylinder 22 fit together to form a cavity for storing liquid. One end of the second connecting pipe 23 is inserted into the upper cylinder 21, and the other end is connected to the first connecting pipe 14; more specifically, one end of the second connecting pipe 23 is fixed to the first connecting pipe 14 by welding. Figure 3 As shown, the inner diameter of the lower section of the upper cylinder 21 is smaller than the inner diameter of the lower cylinder 22, allowing the upper cylinder 21 to be fitted inside the lower cylinder 22 for a tight fit; of course, as Figure 8 As shown, the inner diameter of the lower section of the upper cylinder 21 can also be larger than the inner diameter of the lower cylinder 22, so that the upper cylinder 21 can enclose the lower cylinder 22.

[0045] In a specific embodiment, such as Figure 7 As shown, the liquid storage assembly 2 is located below the housing 5 and cooperates with the bottom of the housing 5. That is to say, in this embodiment, the housing 5 only includes the side plates on both sides, the liquid storage assembly 2 not only realizes the function of liquid storage, but also provides the bottom shell for the entire compressor, and the liquid distribution assembly 1 not only realizes the function of liquid distribution, but also provides the top shell for the entire compressor.

[0046] In a specific embodiment, such as Figure 1 As shown, one side of the housing 5 has an exhaust pipe 51 that communicates with the pump body assembly 3, and the liquid storage assembly 2 is arranged in a ring outside the housing 5 and above the exhaust pipe 51; that is, in this embodiment, the upper cylinder 21 and the lower cylinder 22 are both sleeved on the housing 5, and the entire liquid storage assembly 2 is located above the exhaust pipe 51 and close to the exhaust pipe 51.

[0047] In a specific embodiment, such as Figure 4 As shown, the pump body assembly 3 includes an upper flange 31, a crankshaft 32, a lower flange 33, and a cylinder 34. The upper flange 31, lower flange 33, and cylinder 34 are arranged sequentially from top to bottom, and the crankshaft 32 passes through the upper flange 31, lower flange 33, and cylinder 34 in sequence. The upper flange 31 has a first vent hole 35, and the cylinder 34 has a second vent hole 36. The first vent hole 35 and the second vent hole 36 are connected, so that gas can enter the cavity of the lower flange 33 after passing through the first vent hole 35 and the second vent hole 36. More specifically, the upper flange 31 and the cylinder 34, as well as the lower flange 33 and the cylinder 34, are fixedly assembled by screws 37. In addition, the lower flange 33 has an exhaust valve plate. When the pressure of the refrigerant is higher than the back pressure of the exhaust valve plate, the exhaust valve plate will be opened.

[0048] In a specific embodiment, such as Figure 1As shown, one end of the exhaust pipe 51 is connected to the cavity of the lower flange 33, and the other end extends to the outside of the housing 5; and the part of the exhaust pipe 51 located inside the housing 5 is provided with a sealing ring 52.

[0049] The working principle of the compressor provided in this embodiment is as follows:

[0050] The refrigerant from the air conditioning system first undergoes gas-liquid separation through the liquid separator 1. The gas from the separation point enters the upper cavity of the motor assembly 4 through the second pipe 12 at the bottom of the cylinder 13, and then flows through the flow hole on the motor rotor, the gap between the stator and rotor, the gap of the enameled wire, and the stator tangent to the lower cavity of the motor assembly 4. After that, it enters the suction port (i.e., the second vent 36) of the cylinder 34 through the first vent 35 of the upper flange 31. Then, it is compressed under the combined action of the cylinder 34 and other pump body parts. When the pressure of the compressed refrigerant is higher than the back pressure of the exhaust valve plate on the lower flange 33, the exhaust valve plate is opened, and then the refrigerant enters the cavity of the lower flange 33. Then, it is discharged from the compressor and enters the air conditioning system through the exhaust pipe 51 on the cavity of the lower flange 33. The separated liquid enters the cavity formed by the upper cylinder 21 and the lower cylinder 22 through the first connecting pipe 14 and the second connecting pipe 23, and then is discharged or enters the evaporator of the air conditioner.

[0051] The compressor provided in this embodiment eliminates the compressor top cover, with the cylinder 13 directly serving as the top cover. It is welded to the upper part of the compressor, making the compressor's center of gravity closer to the compressor center, resulting in more stable operation and reducing compressor vibration and noise caused by unbalanced forces. At the same time, since the liquid distribution assembly 1 is located on top, the liquid distributor bracket, liquid distributor pressure plate, rubber pad, etc. are eliminated, which has the advantage of cost saving. Furthermore, by eliminating the liquid distributor bracket and not directly connecting the liquid distributor to the suction pipe, the vibration generated inside the compressor is less likely to be directly transmitted to the liquid distributor, avoiding the problem of excessive liquid distributor vibration.

[0052] Furthermore, the compressor's suction pipe (i.e., the second pipe 12) provided in this embodiment is located at the lower part of the cylinder 13, allowing the intake air to directly reach the upper cavity of the motor assembly 4 to cool the motor and improve its efficiency. The air then enters the cylinder 34 through the first vent hole 35 of the upper flange 31 and is compressed. The compressed refrigerant is then discharged through the lower flange 33 into the cavity of the lower flange 33, and then discharged into the system through the exhaust pipe 51 provided on the lower flange 33 for circulation. In addition, in the compressor provided in this embodiment, the pump assembly 3 is always in the low-pressure chamber, reducing the pressure difference between the inner wall of the compressor housing and the external atmospheric pressure, thereby allowing for the design of a thinner compressor housing and saving development costs.

[0053] In other words, the compressor provided in this embodiment eliminates the distributor bracket and the suction pipe is not directly connected to the pump body assembly. The vibration generated inside the compressor is not easily transmitted directly to the distributor, resulting in excessive vibration of the distributor. At the same time, it can make the center of gravity of the compressor closer to the compressor center and lower the compressor center, making the compressor run more smoothly, thereby avoiding excessive vibration of the compressor due to an unstable center of gravity.

[0057] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.
