Description

Technical Field

[0001] The present disclosure relates to the field of refrigeration equipment, and in particular to a scroll compressor. Background Art

[0002] Scroll compressors are widely used in refrigeration, air conditioning, heat pumps and other fields due to their high efficiency, small size, light weight and smooth operation.

[0003] Specifically, the main structure of the scroll compressor includes a scroll assembly for compressing the refrigerant, and a motor, a shell and a top cover for driving the compression mechanism. The refrigerant gas compressed by the scroll compressor is discharged into the chamber between the shell and the top cover, and then discharged from the exhaust port on the top cover.

[0039] The present disclosure provides a scroll compressor, specifically, the scroll compressor includes a shell, a scroll assembly and a muffler; wherein, a pressure isolation plate is provided in the shell, and the shell is divided into a high-pressure chamber and a low-pressure chamber by the pressure isolation plate; the scroll assembly is provided in the low-pressure chamber, a compression chamber for compressing refrigerant gas is formed in the scroll assembly, and is configured to be controlled by a motor to compress the refrigerant gas and discharge the compressed refrigerant gas to the high-pressure chamber; the muffler is located in the high-pressure chamber and is fixedly provided on the shell to absorb the noise generated during the process of discharging the compressed refrigerant gas into the high-pressure chamber.

[0040] In this way, during the operation of the scroll compressor disclosed herein, the scroll assembly can be controlled by the motor to compress the refrigerant gas and discharge the compressed refrigerant gas into the high-pressure chamber. When the compressed refrigerant gas is discharged into the high-pressure chamber and flows through the muffler located in the high-pressure chamber, the muffler can effectively absorb the noise generated during the process of the compressed refrigerant gas being discharged into the high-pressure chamber, thereby reducing the noise generated during the operation of the scroll compressor disclosed herein, improving the quietness of the operation of the scroll compressor disclosed herein, and thus improving the user experience. In addition, since the muffler is fixedly arranged on the housing, the size of the muffler can be less susceptible to other structural restrictions. While ensuring that the exhaust resistance is small, the muffler effect of the muffler disclosed herein can be effectively improved, and the installation is simple and low-cost.

[0041] For ease of understanding, refer to Figures 1 to 6 , the specific structure and working principle of the scroll compressor disclosed in the present invention are explained in detail with reference to an embodiment.

[0042] like Figures 1 to 4As shown, the present disclosure provides a scroll compressor, specifically, the scroll compressor includes a shell, a scroll assembly (not shown in the figure) and a muffler 3; wherein, a pressure isolation plate 2 is provided in the shell, and the shell is divided into a high-pressure chamber 4 and a low-pressure chamber by the pressure isolation plate 2; the scroll assembly is provided in the low-pressure chamber, and a compression chamber for compressing refrigerant gas is formed in the scroll assembly, and is configured to be controlled by a motor to compress the refrigerant gas and discharge the compressed refrigerant gas to the high-pressure chamber 4; the muffler 3 is located in the high-pressure chamber 4 and is fixedly provided on the shell to absorb the noise generated during the process of discharging the compressed refrigerant gas into the high-pressure chamber 4.

[0043] In this way, during the operation of the scroll compressor disclosed herein, the scroll assembly can be controlled by the motor to compress the refrigerant gas and discharge the compressed refrigerant gas to the high-pressure chamber 4. When the compressed refrigerant gas is discharged to the high-pressure chamber 4 and flows through the muffler 3 located in the high-pressure chamber 4, the muffler 3 can effectively absorb the noise generated during the process of the compressed refrigerant gas being discharged to the high-pressure chamber 4, thereby reducing the noise generated during the operation of the scroll compressor disclosed herein, improving the quietness of the operation of the scroll compressor disclosed herein, and thus improving the user experience. In addition, since the muffler 3 is fixedly arranged on the shell, the size of the muffler 3 can be less susceptible to other structural restrictions. While ensuring that the exhaust resistance is small, the muffler effect of the muffler 3 disclosed herein can be effectively improved, and the installation is simple and low-cost.

[0044] like Figures 3 to 6 As shown, in one embodiment of the present disclosure, the muffler 3 is provided with a muffler hole 33. The compressed refrigerant gas is configured to reduce the noise generated when flowing through the muffler hole 33. During the operation of the scroll compressor of the present disclosure, the compressed refrigerant gas flows through the muffler 3 located in the high-pressure chamber 4, and the noise generated when passing through the muffler hole 33 can be effectively reduced.

[0045] Specifically, in one embodiment of the present disclosure, the muffler 3 is configured to be fixed to the top cover 1 by at least one of resistance welding, welding, or threaded connection. Resistance welding, welding, or threaded connection effectively secures the muffler 3 to the top cover 1, effectively ensuring a fixed connection between the muffler 3 and the top cover 1 while also reducing processing costs, facilitating installation, and simplifying assembly.

[0046] like Figure 3 As shown, in one embodiment of the present disclosure, the housing includes a top cover 1, a high-pressure chamber 4 is defined between the top cover 1 and a pressure isolation plate 2, and a muffler 3 is fixedly mounted on the top cover 1. Since the muffler 3 is fixedly mounted on the top cover 1, the size of the muffler 3 is less susceptible to structural limitations. This ensures low exhaust resistance while effectively improving the muffler effect of the muffler 3 of the present disclosure, and the installation is simple and cost-effective.

[0047] like Figure 3 As shown, in one embodiment of the present disclosure, an exhaust port 11 is provided on the main top cover 1; the compressed refrigerant gas discharged into the high-pressure chamber 4 is configured to at least partially pass through the muffler hole 33 before being completely discharged from the exhaust port 11. That is, during the operation of the scroll compressor of the present disclosure, the scroll compressor below the pressure isolation plate 2 will discharge the compressed refrigerant gas into the high-pressure chamber 4 above the pressure isolation plate 2, and the compressed refrigerant gas discharged into the high-pressure chamber 4 will partially or completely pass through the muffler hole 33. After the muffler hole 33 absorbs part of the noise generated during the process of the compressed refrigerant gas being discharged into the high-pressure chamber 4, the refrigerant gas will be completely discharged from the exhaust port 11.

[0048] like Figure 3 As shown, in one embodiment of the present disclosure, the bottom edge of the silencer 3 is constructed so that the gap between it and the pressure isolation plate 2 in the vertical direction is smaller than the preset size. Since the gap between the bottom edge of the silencer 3 and the pressure isolation plate 2 in the vertical direction is smaller than the preset size, more refrigerant gas can enter the silencer 3 and be discharged from the exhaust port 11 after passing through the silencer hole 33, thereby reducing the proportion of refrigerant gas that does not flow through the silencer 3 and is directly discharged from the exhaust port 11, thereby effectively improving the silencing effect of the silencer 3 of the present disclosure.

[0049] Similar, such as Figure 3 As shown, in one embodiment of the present disclosure, the bottom edge of the muffler 3 is constructed to be in contact with the pressure isolation plate 2 in the vertical direction. Since the bottom edge of the muffler 3 is in contact with the pressure isolation plate 2 in the vertical direction, more refrigerant gas can enter the muffler 3 and be discharged from the exhaust port 11 after passing through the muffler hole 33, thereby minimizing the proportion of refrigerant gas that does not flow through the muffler 3 and is discharged directly from the exhaust port 11, thereby further improving the silencing effect of the muffler 3 of the present disclosure.

[0050] Specifically, in one embodiment of the present disclosure, the bottom edge of the muffler 3 is constructed so that the gap between it and the pressure isolation plate 2 in the vertical direction is less than 10 mm. Since the gap between the bottom edge of the muffler 3 and the pressure isolation plate 2 in the vertical direction is less than 10 mm, it can effectively ensure that more refrigerant gas enters the muffler 3 and is discharged from the exhaust port 11 after passing through the muffler hole 33, reducing the proportion of refrigerant gas that does not flow through the muffler 3 and is discharged directly from the exhaust port 11, thereby effectively improving the silencing effect of the muffler 3 of the present disclosure.

[0051] like Figure 3 and Figure 5As shown, in one embodiment of the present disclosure, an exhaust through hole 21 is provided at the center position of the pressure isolation plate 2, and the vortex assembly is constructed to discharge the compressed refrigerant gas from the exhaust through hole 21 to the high-pressure chamber 4; the muffler 3 is constructed to be arranged at a position above the exhaust through hole 21.

[0052] In this way, during the operation of the scroll compressor disclosed in the present invention, the scroll compressor will discharge the compressed refrigerant gas from the exhaust through hole 21 set at the center position of the pressure isolation plate 2 to the high-pressure chamber 4 above the pressure isolation plate 2; since the muffler 3 is set at a position above the exhaust through hole 21, when the refrigerant gas is discharged from the exhaust through hole 21 to the high-pressure chamber 4 above the pressure isolation plate 2, it can enter the muffler 3 and flow through the muffler hole 33 on the muffler 3. In the process of the refrigerant gas flowing through the muffler 3, the muffler 3 can effectively absorb the noise generated during the flow of the compressed refrigerant gas.

[0053] Further, such as Figure 3 and Figure 5 As shown, in one embodiment of the present disclosure, the muffler 3 is constructed so that its projection on the horizontal plane completely covers the projection of the exhaust through-hole 21 on the horizontal plane. Since the projection of the muffler 3 on the horizontal plane completely covers the projection of the exhaust through-hole 21 on the horizontal plane, the coverage area of the muffler 3 can be effectively increased. As a result, after the refrigerant gas is discharged from the exhaust through-hole 21 into the high-pressure chamber 4 above the pressure isolation plate 2, almost all of the refrigerant gas can enter the muffler 3, flow through the muffler holes 33 on the muffler 3, and be discharged from the exhaust port 11, effectively improving the noise reduction performance of the muffler 3 of the present disclosure.

[0054] Further, such as Figure 3 and Figure 5 As shown, in one embodiment of the present disclosure, the projected area of the muffler 3 on the horizontal plane is 1 to 6 times the projected area of the exhaust through-hole 21 on the horizontal plane. When the projected area of the muffler 3 on the horizontal plane is within the range of 1 to 6 times the projected area of the exhaust through-hole 21 on the horizontal plane, it is possible for the projection of the muffler 3 on the horizontal plane to completely cover the projection of the exhaust through-hole 21 on the horizontal plane, so that almost all refrigerant gas can enter the muffler 3 and flow through the muffler hole 33 on the muffler 3 and then be discharged from the exhaust port 11, effectively improving the noise reduction performance of the muffler 3 of the present disclosure, and under the premise of ensuring the noise reduction performance, the overall size of the muffler 3 will not be expanded, thereby reducing the overall size of the scroll compressor of the present disclosure.

[0055] In one embodiment of the present disclosure, a one-way valve (not shown in the figure) is provided on the exhaust through hole 21; the one-way valve is constructed to open when the compressed refrigerant fluid flows out of the exhaust through hole 21 when the scroll assembly is working; and close after the scroll assembly is shut down; the muffler 3 is configured to cover the exhaust through hole 21 to absorb the working noise of the one-way valve.

[0056] Thus, during the operation of the scroll compressor disclosed herein, when the scroll assembly is operating, the compressed refrigerant fluid can open the one-way valve when it flows out of the exhaust through-hole 21, thereby allowing the refrigerant gas to flow from the opened one-way valve to the high-pressure chamber 4 and then be discharged from the exhaust port 11; after the scroll assembly is shut down, the one-way valve can be closed in time, thereby effectively preventing the refrigerant fluid from flowing back from the exhaust through-hole 21 and causing damage to the scroll assembly. Furthermore, since the muffler 3 covers the exhaust through-hole 21, it can absorb the operating noise of the one-way valve, further reducing the various noises generated by the scroll compressor disclosed herein during operation, improving the operating quietness of the scroll compressor disclosed herein, and thereby improving the user experience.

[0057] In another embodiment of the present disclosure, the one-way valve may also be directly provided on the fixed scroll member, with similar effects, which will not be described in detail here.

[0058] Specifically, such as Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the muffler 3 includes a main body portion 31, the top of the main body portion 31 is fixedly arranged on the top cover 1, the bottom of the main body portion 31 is provided with an opening 32, and the opening 32 is constructed to correspond to the exhaust through hole 21, and at least one muffler hole 33 is provided on the side wall of the main body portion 31.

[0059] Since the bottom of the main body 31 of the muffler 3 is provided with an opening 32, which corresponds to the exhaust through-hole 21, and at least one silencer hole 33 is provided on the side wall of the main body 31, after the compressed refrigerant gas is discharged from the exhaust through-hole 21 provided at the center of the pressure isolation plate 2 into the high-pressure chamber 4 above the pressure isolation plate 2, it will enter the inner cavity surrounded by the main body 31 of the muffler 3 from the bottom opening 32 of the muffler 3, and then flow out from the silencer hole 33 on the side wall of the main body 31; in this process, the muffler 3 can effectively absorb the noise generated during the flow of the compressed refrigerant gas, thereby reducing the operating noise of the scroll compressor disclosed herein and improving the operating quietness of the scroll compressor disclosed herein.

[0060] Further, such as Figure 3As shown, in one embodiment of the present disclosure, the main body portion 31 includes a frustum portion 311 and a bottom edge portion 312 connected from top to bottom, the frustum portion 311 is constructed so that the inner diameter continuously increases in the extension direction from the top to the bottom, and the bottom edge portion 312 is constructed so that the inner diameter remains unchanged in the extension direction from the top to the bottom.

[0061] In this way, the bottom edge portion 312 can effectively ensure that the compressed refrigerant gas enters the inner cavity surrounded by the main body portion 31 of the muffler 3 from the bottom opening 32 of the muffler 3. Then, during the flow of the refrigerant gas in the inner cavity of the main body portion 31, it can be continuously gathered under the action of the frustum portion 311 until it flows out from the muffler hole 33 on the side wall of the main body portion 31. Because the frustum portion 311 can continuously gather the refrigerant gas during the flow process, the noise generated during the flow of the refrigerant gas can be effectively reduced, thereby improving the muffler effect of the muffler 3 of the present disclosure.

[0062] like Figure 6 As shown, in one embodiment of the present disclosure, at least two silencer chambers 34 are provided in the muffler 3, and the silencer chambers 34 are interconnected through silencer holes 33. The refrigerant gas discharged from the exhaust through-hole 21 is configured to pass through each silencer chamber 34 before being discharged into the high-pressure chamber 4. In this way, after the refrigerant gas enters the muffler 3 through the exhaust through-hole 21, it can pass through each of the interconnected silencer chambers 34 before being discharged into the high-pressure chamber 4. After passing through the silencer holes on each silencer chamber 34, the noise generated during the flow of the refrigerant gas can be reduced, thereby improving the silencer effect of the muffler 3 of the present disclosure.

[0063] Further, such as Figure 6 As shown, in one embodiment of the present disclosure, the silencer chamber 34 includes an inner chamber connected to the exhaust through-hole 21 and an outer chamber located radially outside the inner chamber; partitions are provided between each silencer chamber 34; silencer holes 33 are provided on the partitions; each silencer chamber 34 is connected to each other through the silencer holes 33, and the refrigerant gas discharged from the exhaust through-hole 21 is constructed to pass through the inner chamber, and then be divided into at least one path through the outer chamber and discharged into the high-pressure chamber 4.

[0064] In this way, after the refrigerant gas is discharged from the exhaust hole 21, it first enters the inner chamber, and then is divided into at least one path through the partition to enter the outer chamber, and then discharged into the high-pressure chamber 4. In each silencer chamber 34, the noise generated during the flow of the refrigerant gas can be reduced to improve the silencer effect of the silencer 3 of the present disclosure. It can be understood that if Figure 6 As shown, the flow path of the refrigerant gas can be only one path, or can be two or more paths, which is not limited here.

[0065] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terms used herein are selected to best explain the principles of the embodiments, their practical applications, or technical improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
