Description

Technical Field

[0001] The invention belongs to the technical field of mufflers, and more specifically, relates to a flow guide muffler and a compressor and an air conditioner using the muffler. Background Art

[0002] A muffler is a device that blocks sound transmission but allows airflow to pass through. It is an important measure to eliminate aerodynamic noise. A muffler is a noise-reducing device installed in the airflow channel or in the intake and exhaust system of aerodynamic equipment (such as blowers, air compressors, boiler exhaust ports, generators, water pumps and other equipment with high exhaust noise).

[0003] Most existing mufflers adopt a petal-shaped structure, relying on the concave-convex structure of the inner cavity of the muffler to diffusely reflect the sound and finally discharge it out of the muffler, avoiding the airflow noise caused by direct exhaust from the flange exhaust port and achieving the purpose of noise reduction.

[0004] However, traditional mufflers are limited by the size of the petal volume, so that the gas discharged from the flange accumulates in the muffler and is exhausted only by the gap in the shaft diameter or by opening exhaust holes on the petal surface. This not only has a poor noise reduction effect and increases the power of the compressor, but also because the muffler exhaust is directly discharged, the lubricating oil is discharged from the pump body together with the refrigerant, which increases the oil content of the compressor and further reduces the energy efficiency of the compressor. Summary of the invention

[0005] The object of the present invention is to provide a flow guide silencer to solve the problems of poor noise reduction effect and high oil content in the compressor in the prior art.

[0006] To achieve the above object, the technical solution adopted by the present invention is: to provide a guide silencer, including a shell with multiple exhaust holes, at least one guide plate is arranged in the shell, and multiple expansion silencers are arranged on the guide plate.

[0007] Preferably, a first guide plate and a second guide plate arranged in sequence are provided in the shell, and a plurality of evenly arranged expansion silencers are provided on the first guide plate and the second guide plate.

[0008] Preferably, the expansion muffler on the first guide plate and the expansion muffler on the second guide plate are staggered.

[0009] Furthermore, the expansion muffler includes a vent hole and an expansion chamber vertically connected to the vent hole.

[0010] Furthermore, the first guide plate and the second guide plate divide the interior of the shell into a first chamber, a second chamber and a third chamber from bottom to top, and the exhaust hole is opened on the side wall of the shell and connected to the third chamber.

[0011] Preferably, the size of the shell gradually decreases from bottom to top, so that the space of the first chamber is larger than the space of the second chamber, and the space of the second chamber is larger than the space of the third chamber.

[0012] Furthermore, a mounting portion bent outward is provided at the bottom of the shell.

[0013] Furthermore, the mounting portion is provided with a plurality of mounting holes.

[0014] Another object of the present invention is to provide a compressor, comprising the above-mentioned flow guide muffler.

[0015] Another object of the present invention is to provide an air conditioner, wherein the compressor of the air conditioner includes the above-mentioned flow guide silencer.

[0016] The beneficial effect of the guide silencer provided by the present invention is that, compared with the prior art, multiple guide plates are arranged in the shell, and multiple expansion silencers are arranged on the guide plates, so that the refrigerant is subjected to multiple noise reduction and gas-liquid separation, which greatly reduces the noise and oil content, improves the efficiency of noise reduction and oil content reduction, and conforms to humanized and industrialized design.

[0028] See also Figure 1, the flow guide silencer provided by the embodiment of the present invention is now described. The flow guide silencer comprises a shell 1, the shell 1 is provided with a plurality of exhaust holes 2, at least one flow guide plate is arranged in the shell 1, and a plurality of expansion silencers 5 are arranged on the flow guide plate. During the exhaust process, the refrigerant first enters the cavity formed by the first flow guide plate and the shell 1 for noise reduction and gas-liquid separation, and then passes through the expansion silencer 5 on the first flow guide plate for the second noise reduction, and so on. After multiple noise reductions and gas-liquid separations, the noise and oil content are greatly reduced.

[0029] Compared with the prior art, the guide silencer provided by the present invention has multiple guide plates arranged in the shell 1, and multiple expansion silencers 5 are arranged on the guide plates, so as to perform multiple noise reduction and gas-liquid separation on the refrigerant, greatly reduce the noise and oil content, improve the efficiency of noise reduction and oil content reduction, and conform to humanized and industrialized design.

[0030] Preferably, see Figure 1 As a specific embodiment of the guide silencer provided by the present invention, a first guide plate 3 and a second guide plate 4 are arranged in the shell 1, the first guide plate 3 is located below the second guide plate 4, and a plurality of expansion silencers 5 are arranged on the first guide plate 3 and the second guide plate 4. After the refrigerant passes through the first guide plate 3, the expansion silencer 5 on the first guide plate 3, the second guide plate 4, and the expansion silencer 5 on the second guide plate 4, multiple noise reduction and gas-liquid separation occur, which greatly improves the noise reduction effect and reduces the oil content.

[0031] Preferably, see Figure 1 The expansion muffler 5 on the first guide plate 3 and the expansion muffler 5 on the second guide plate 4 are staggered, making it more difficult for the refrigerant to enter the expansion muffler 5 on the second guide plate 4 from the expansion muffler 5 on the first guide plate 3, thereby extending the flow path of the refrigerant, making the refrigerant diffusely reflected for a longer time, making the noise reduction and gas-liquid separation process more complete, and enhancing the noise reduction effect of the refrigerant.

[0032] For further information, see Figure 1 The expansion muffler 5 includes a vent hole 51 and an expansion chamber 52, wherein the vent hole 51 and the expansion chamber 52 are vertically connected. When the refrigerant enters the expansion muffler 5, it first enters the vent hole 51, then enters the expansion chamber 52 for diffuse reflection to silence the sound, and finally exits the expansion chamber 52 and is discharged through the vent hole 51. This makes it more difficult for the refrigerant to enter the second vent hole 51 from the first vent hole 51, which is convenient for extending the flow path of the refrigerant, making the refrigerant diffuse reflection longer, making the noise reduction and gas-liquid separation process more complete, and enhancing the noise reduction effect of the refrigerant.

[0033] For further information, see Figure 1, the first guide plate 3 and the second guide plate 4 divide the interior of the shell 1 into a first chamber 6, a second chamber 7 and a third chamber 8, and the exhaust hole 2 is opened on the side wall of the shell 1, and the exhaust hole 2 is connected to the third chamber 8. First, the refrigerant enters the first chamber 6, and undergoes the first noise reduction and gas-liquid separation; then, the refrigerant passes through the expansion silencer 5 on the first guide plate 3 for the second noise reduction; then, it enters the second chamber 7 through the first vent 51, and undergoes the third noise reduction and the second gas-liquid separation; then, it passes through the expansion silencer 5 on the second guide plate 4 for the fourth noise reduction; then, it enters the third chamber 8 through the second vent 51, and undergoes the fifth noise reduction and the third gas-liquid separation, and finally is discharged from the exhaust hole 2. The whole process undergoes five noise reductions and three gas-liquid separations, which greatly reduces the noise and oil content. Of course, in other embodiments, the number of guide plates can also be selected according to actual conditions.

[0034] Preferably, as another specific embodiment of the guide silencer provided by the present invention, a first guide plate 3, a second guide plate 4 and a third guide plate are arranged in the shell 1, and the first guide plate 3, the second guide plate 4 and the third guide plate are arranged in sequence from bottom to top. The first guide plate 3, the second guide plate 4 and the third guide plate are all provided with a plurality of evenly arranged expansion silencers 5. According to the above noise reduction and gas-liquid separation process, the three guide plates can make the refrigerant undergo seven noise reductions and four gas-liquid separations. The more the number of guide plates and expansion silencers 5, the better the noise reduction effect. Of course, in other embodiments, the number of guide plates and the number of expansion silencers 5 can be selected according to actual conditions and needs, and will not be repeated here.

[0035] Preferably, see Figure 1 The radial dimension of the shell 1 decreases gradually from bottom to top, and the spaces of the first chamber 6, the second chamber 7, and the third chamber 8 decrease successively. In the process of the refrigerant moving from the first chamber 6 to the second chamber 7 and then to the third chamber 8, the diffuse reflection process becomes more intense due to the gradual reduction of the space, which makes the noise reduction and gas-liquid separation effects better.

[0036] For further information, see Figure 1 The bottom of the shell 1 is provided with a mounting portion 9 bent outward, and the shell 1 can be fixed on a flange plate through the mounting portion 9 during installation.

[0037] For further information, see Figure 1 A plurality of mounting holes 10 are provided on the mounting portion 9, so that the connecting parts can pass through the mounting holes 10 to fix the connecting plate.

[0038] The present invention also provides a compressor, comprising the above-mentioned flow guide silencer.

[0039] The present invention further provides an air conditioner, wherein the compressor of the air conditioner comprises the above-mentioned flow guide silencer.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
