Technical Field

[0001] The present invention relates to the technical field of mufflers, and particularly to an intake muffler, a compressor, and a household appliance. Background Art

[0002] A refrigerator is one of the commonly used household appliances in modern residents' lives. With the improvement of people's living standards, people's requirements for the noise and energy consumption of refrigerators are also getting higher and higher. The compressor is the heart of the refrigerator, and the intake structure is an important intake air flow passage of the compressor. The design of the intake structure in the compressor needs to consider both noise and cooling capacity and coefficient of performance (COP). How to balance noise and energy consumption has become an important research point in the design of the intake structure of the compressor. Summary of the Invention

[0003] The main object of the present invention is to provide an intake muffler, aiming to balance noise and energy consumption.

[0004] To achieve the above object, the intake muffler proposed by the present invention includes:

[0005] A housing having a muffling chamber; and

[0006] A partition assembly disposed in the muffling chamber and dividing the muffling chamber into a first chamber and a second chamber. The partition assembly has a first flow passage and a second flow passage. Both the first flow passage and the second flow passage communicate the first chamber and the second chamber. The second flow passages are multiple, and the multiple second flow passages are arranged at intervals and surround the first flow passage.

[0007] In one embodiment, the partition assembly includes a connecting pipe, and both the first flow passage and the second flow passage are located on the connecting pipe.

[0008] In one embodiment, the partition assembly further includes a partition plate disposed at the boundary between the first chamber and the second chamber. The partition plate is provided with an installation hole, and the connecting pipe is inserted into the installation hole;

[0009] The connecting pipe is inserted into the installation hole with interference;

[0010] Alternatively, a gap flow passage is formed between the outer wall of the connecting pipe and the inner wall of the installation hole.

[0011] In one embodiment, the partition assembly includes a partition plate and a connecting pipe. The partition plate is disposed at the boundary between the first chamber and the second chamber. The connecting pipe passes through the partition plate. The first flow passage is located on the connecting pipe, and the second flow passage is located on the partition plate.

[0012] In one embodiment, the partition plate is provided with mounting holes which are located in the area enclosed by a plurality of the second channels, and the communication pipe is inserted through the mounting holes;

[0013] Alternatively, the partition plate is provided with mounting holes, the communication pipe is inserted through the mounting holes, and the outer wall of the communication pipe is connected to the inner wall of the mounting holes by a plurality of connecting ribs. The plurality of connecting ribs are arranged at intervals and surround the communication pipe, and define a plurality of the second flow channels.

[0014] In one embodiment, the communication pipe is a straight pipe or a bent pipe.

[0015] In one embodiment, the cross-section of the second flow channel is circular, arc-shaped or irregular. The irregular shape includes a first arc segment, a second arc segment, a third arc segment and a fourth arc segment which are connected in sequence end to end. The first arc segment corresponds to the third arc segment and constitutes the arc-shaped part of the irregular shape, and the second arc segment and the fourth arc segment correspond to each other and constitute the two circular parts of the irregular shape.

[0016] In one embodiment, the suction muffler further includes an outlet pipe which has a third flow channel and a fourth flow channel, and both the third flow channel and the fourth flow channel communicate with the second cavity.

[0017] In one embodiment, the first cavity, the partition assembly and the second cavity are arranged in a first direction;

[0019] The present invention also provides a compressor, including the above-mentioned suction muffler.

[0020] The present invention also provides a household appliance, including the above-mentioned compressor.

[0021] When using the above-mentioned suction muffler, the refrigerant enters the first cavity, then enters the second cavity through the partition component, and finally is discharged. Due to the cooperation of the first cavity, the partition component and the second cavity, the suction noise of the compressor is reduced. Moreover, compared with the flow channel including only the first flow channel, the composite flow channel including both the first flow channel and the auxiliary second flow channel has a smaller fluid flow resistance, higher cooling capacity, and lower input, so that the energy efficiency ratio of the compressor can be improved. And compared with the flow channel including only one large inner diameter (the inner diameter of which is approximately the same as the inner diameter of the flow channel formed by enclosing multiple second flow channels), the acoustic impedance of the composite flow channel including both the first flow channel and the second flow channel increases, and the sound absorption effect is better. Therefore, the above-mentioned suction muffler can take into account both noise and energy consumption, and can achieve the effect of having a high energy efficiency ratio while reducing noise. Moreover, compared with the method of only arranging a second flow channel outside the first flow channel, the method of arranging multiple second flow channels at intervals and surrounding the first flow channel can better take into account both noise and energy consumption.

[0042] The present invention provides an intake silencer.

[0043] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the intake silencer 10 includes a housing 200 and a partition assembly 300.

[0044] The housing 200 has a silencing chamber 202, an air inlet 204 and an air outlet 206 that communicate with the silencing chamber 202.

[0045] The partition assembly 300 is disposed in the silencing chamber 202 and divides the silencing chamber 202 into a first chamber 202a that communicates with the air inlet 204 and a second chamber 202b that communicates with the air outlet 206. The partition assembly 300 has a first flow channel 302 and a second flow channel 304 located outside the first flow channel 302. Both the first flow channel 302 and the second flow channel 304 communicate the first chamber 202a and the second chamber 202b.

[0046] When using the above-mentioned intake silencer 10, the refrigerant enters the first cavity 202a through the intake port 204, then enters the second cavity 202b through the partition component 300, and finally is discharged through the outlet port 206. Due to the cooperation of the intake port 204, the first cavity 202a, the partition component 300, the second cavity 202b and the outlet port 206, the intake noise of the compressor is reduced. Moreover, compared with the flow channel that only includes the first flow channel 302, the composite flow channel that includes both the first flow channel 302 and the auxiliary second flow channel 304 has a smaller fluid flow resistance, higher cooling capacity, and lower input, so that the energy efficiency ratio of the compressor can be improved. And compared with the flow channel that only includes a large inner diameter flow channel (whose flow area is approximately the same as the sum of the flow areas of the first flow channel 302 and the second flow channel 304), the acoustic impedance of the composite flow channel that includes both the first flow channel 302 and the second flow channel 304 increases, and the sound absorption effect is better. Therefore, the above-mentioned intake silencer 10 can balance noise and energy consumption, and can achieve the effect of having a high energy efficiency ratio while reducing noise.

[0047] In this embodiment, there are multiple second flow channels 304, and the multiple second flow channels 304 are arranged at intervals and surround the first flow channel 302. Compared with the method of only arranging one second flow channel 304 outside the first flow channel 302, the method of arranging the multiple second flow channels 304 at intervals and surrounding the first flow channel 302 can better balance noise and energy consumption.

[0048] In this embodiment, the multiple second flow channels 304 are arranged at intervals and surround the first flow channel 302 for one week. Specifically, in this embodiment, the multiple second flow channels 304 are arranged at equal intervals. In this way, the refrigerant can flow more uniformly on the outer periphery of the first flow channel 302. It can be understood that in other embodiments, the multiple second flow channels 304 can also surround the first flow channel 302 for multiple weeks, and it is not limited to the multiple second flow channels 304 surrounding the first flow channel 302 for one week.

[0049] In this embodiment, the partition component 300 includes a communication pipe 310. Both the first flow channel 302 and the second flow channel 304 are located on the communication pipe 310. That is, in this embodiment, the first flow channel 302 and the second flow channel 304 are integrated on the same communication pipe 310. Compared with the method of setting two communication pipes, one communication pipe has the first flow channel 302 and the other communication pipe has the second flow channel 304, the method of integrating the first flow channel 302 and the second flow channel 304 on the same communication pipe 310 can simplify the structure of the partition component 300, and is more conducive to designing the first flow channel 302 as the main flow channel and the second flow channel 304 as the auxiliary flow channel, and through the cooperation of the large flow area of the main flow channel and the small and many small flow areas of the auxiliary flow channel, the noise and energy consumption can be better balanced.

[0050] In this embodiment, the partition component 300 further includes a partition plate 320. The partition plate 320 is disposed in the sound absorption cavity 202 and divides the sound absorption cavity 202 into a first cavity 202a and a second cavity 202b, that is, the partition plate 320 is disposed at the boundary between the first cavity 202a and the second cavity 202b. The communication pipe 310 penetrates through the partition plate 320. By providing the partition plate 320, it is very convenient to implement that the partition component 300 divides the sound absorption cavity 202 into the first cavity 202a and the second cavity 202b. It can be understood that in other embodiments, when the cross-sectional area of the communication pipe 310 is large enough to satisfy that the communication pipe 310 divides the sound absorption cavity 202 into the first cavity 202a and the second cavity 202b, that is, when the communication pipe 310 integrates the two functions of conducting and partitioning the first cavity 202a and the second cavity 202b, the above-mentioned partition plate 320 can be omitted to achieve the effect of simplifying the structure of the partition component 300.

[0051] In this embodiment, the partition plate 320 is provided with an installation hole 322, and the communication pipe 310 penetrates through the installation hole 322. Among them, the outer wall of the communication pipe 310 and the inner wall of the installation hole 322 may be hermetically connected or may not be hermetically connected.

[0052] In this embodiment, the outer wall of the communication pipe 310 is hermetically connected to the inner wall of the installation hole 322. For example, in some embodiments, the communication pipe 310 and the partition plate 320 are integrally formed. At this time, it can be considered that the outer wall of the communication pipe 310 is hermetically connected to the inner wall of the installation hole 322; again, for example, in some embodiments, the communication pipe 310 and the installation hole 322 are in interference fit. At this time, it can also be considered that the outer wall of the communication pipe 310 is hermetically connected to the inner wall of the installation hole 322. The hermetic connection between the outer wall of the communication pipe 310 and the inner wall of the installation hole 322 is very convenient for the firm connection between the communication pipe 310 and the partition plate 320.

[0053] In other embodiments, as Figure 3 shown, the outer wall of the communication pipe 310 and the inner wall of the installation hole 322 may also not be hermetically connected, that is, there may be a gap between the outer wall of the communication pipe 310 and the inner wall of the installation hole 322. At this time, it can be considered that a gap flow channel 306 is formed between the outer wall of the communication pipe 310 and the inner wall of the installation hole 322. In this way, it is more conducive to the above-mentioned suction muffler 10 to take into account both noise and energy consumption, and achieve the effect of having a high energy efficiency ratio while reducing noise.

[0054] In some embodiments, as Figure 3 shown, when the communication pipe 310 and the installation hole 322 are in clearance fit, at this time, it can be considered that there is an annular gap flow channel 306 outside the communication pipe 310, and the annular gap flow channel 306 surrounds the communication pipe 310. In some embodiments, as Figure 4As shown, the outer wall of the connecting pipe 310 is connected to the inner wall of the mounting hole 322 by a plurality of connecting ribs 330. The plurality of connecting ribs 330 are arranged at intervals and surround the connecting pipe 310, thereby defining a plurality of gap channels 306.

[0055] In other embodiments, as Figure 5 As shown, the partition assembly 300 includes a connecting pipe 310 and a partition plate 320. The partition plate 320 is disposed in the sound absorption cavity 202 and divides the sound absorption cavity 202 into a first cavity 202a and a second cavity 202a. The connecting pipe 310 passes through the partition plate 320. Among them, the first flow channel 302 is located on the connecting pipe 310, and the second flow channel 304 is located on the partition plate 320. It is relatively easy to form the second flow channel 304 on the partition plate 320. By arranging the second flow channel 304 on the partition plate 320, an existing pipe can be used as the connecting pipe 310, so that there is no need to additionally design and / or manufacture the connecting pipe 310, thereby reducing the design and / or manufacturing difficulty of the partition assembly 300 and achieving the effect of reducing the cost of the partition assembly 300.

[0056] In some embodiments, as Figure 5 As shown, a plurality of second flow channels 304 are formed on the partition plate 320. The plurality of second flow channels 304 are arranged at intervals and surround the connecting pipe 310. The partition plate 320 is formed with a mounting hole 322. The mounting hole 322 is located in the area surrounded by the plurality of second channels 304. The connecting pipe 310 having the first flow channel 302 passes through the mounting hole 322. It should be noted that at this time, the outer wall of the connecting pipe 310 can be hermetically connected to the inner wall of the mounting hole 322, or can be non-hermetically connected to the inner wall of the mounting hole 322. When the outer wall of the connecting pipe 310 is non-hermetically connected to the inner wall of the mounting hole 322, a Figure 3 or Figure 4 The gap channel 306 shown is formed between the first flow channel 302 and the second flow channel 304.

[0057] In some embodiments, as Figure 6 As shown, the partition plate 320 is provided with a mounting hole 322. The connecting pipe 310 having the first flow channel 302 passes through the mounting hole 322, and the outer wall of the connecting pipe 310 is connected to the inner wall of the mounting hole 322 by a plurality of connecting ribs 330. The plurality of connecting ribs 330 are arranged at intervals and surround the connecting pipe 310, and define a plurality of second flow channels 304. At this time, Figure 6 The second flow channel 304 shown in Figure 4 is substantially the same as the gap channel 306 shown in

[0058] In this embodiment, as Figure 1 and Figure 2As shown, the connecting pipe 310 passes through the mounting hole 322, and one end of the connecting pipe 310 extends into the first cavity 202a, and the other end of the connecting pipe 310 extends into the second cavity 202b. In this way, without changing the thickness of the partition 320, the connecting pipe 310 can have a longer length, which is more conducive to noise reduction. It can be understood that in other embodiments, one end of the connecting pipe 310 may also extend into the first cavity 202a or the second cavity 202b, while the other end of the connecting pipe 310 is received in the mounting hole 322 of the partition 320. It can be understood that in other embodiments, when the thickness of the partition 320 is relatively large and the length of the connecting pipe 310 is relatively short, both ends of the connecting pipe 310 may also be substantially flush with both sides of the partition 320, that is, neither end of the connecting pipe 310 extends into the first cavity 202a and the second cavity 202b, but is received in the mounting hole 322.

[0059] In some embodiments, as Figure 1 and Figure 2 shown, the connecting pipe 310 is a straight pipe. In some embodiments, as Figure 7 shown, the connecting pipe 310 is a bent pipe. In the arrangement direction of the first cavity 202a and the second cavity 202b, a bent pipe with the same projected length has a longer flow path length than a straight pipe, which is more conducive to taking into account both noise and energy consumption.

[0060] In some embodiments, as Figure 1 and Figure 2 shown, the number of the first flow channels 302 is one, the cross-sectional shape of the first flow channel 302 is circular, the number of the second flow channels 304 is ten, and the cross-sectional shape of the second flow channels 304 is circular (ring-shaped). At this time, it can be considered that the cross-section of the connecting pipe 310 has a lotus root-like pattern.

[0061] In some embodiments, as Figure 8 and Figure 9 shown, the number of the first flow channels 302 is one, the cross-sectional shape of the first flow channel 302 is circular, the number of the second flow channels 304 is three, and the cross-sectional shape of the second flow channels 304 is arc-shaped (arc-shaped ring).

[0062] In some embodiments, as Figures 10 - 12As shown in the figure, the cross-sectional shape of the second flow channel 304 is irregular (irregular ring). Among them, the irregular shape includes a first arc segment 304a, a second arc segment 304b, a third arc segment 304c, and a fourth arc segment 304d that are connected in sequence from head to tail. The first arc segment 304a corresponds to the third arc segment 304c and constitutes the arc portion of the irregular shape. The second arc segment 304b and the fourth arc segment correspond to each other and constitute the two circular portions 304d of the irregular shape. At this time, it can be considered that the middle part of the irregular shape is arc-shaped, and the two ends of the irregular shape are circular. Specifically, in this embodiment, the number of the first flow channels 302 is one, the cross-sectional shape of the first flow channel 302 is circular, the number of the second flow channels 304 is five, and the cross-sectional shape of the second flow channel 304 is irregular.

[0063] In the above embodiment, the cross-sectional shape of the second flow channel 304 is circular, arc-shaped or irregular. It can be understood that the cross-sectional shape of the second flow channel 304 is not limited to the above several forms, and can also be any other regular or irregular shape. In the above embodiment, the number of the first flow channels 302 is one, and the cross-sectional shape of the first flow channel 302 is circular. It can be understood that the number of the first flow channels 302 is not limited to one, and the number of the first flow channels 302 can also be multiple (greater than or equal to two). When the number of the first flow channels 302 is multiple, the multiple first flow channels 302 are arranged at intervals. It can be understood that the cross-sectional shape of the first flow channel 302 is not limited to circular, and can also be any other regular or irregular shape, such as the above-mentioned arc shape, the above-mentioned irregular shape.

[0064] In this embodiment, as Figure 1 shown, the suction muffler 10 further includes an inlet pipe 400. The inlet pipe 400 is communicated with the first cavity 202a through the air inlet 204. The setting of the inlet pipe 400 is very convenient for discharging the refrigerant into the suction muffler 10.

[0065] In this embodiment, the inlet pipe 400 is penetrated through the air inlet 204, and one end of the inlet pipe 400 close to the partition assembly 300 extends into the first cavity 202a. In this way, it is very convenient for the inlet pipe 400 to be communicated with the first cavity 202a through the air inlet 204. It can be understood that in other embodiments, one end of the inlet pipe 400 close to the partition assembly 300 may not extend into the first cavity 202a, but be received in the air inlet 204. It should be noted that in this embodiment, the outer wall of the inlet pipe 400 is hermetically connected to the inner wall of the air inlet 204. For example, the inlet pipe 400 and the air inlet 204 are in interference fit.

[0066] In this embodiment, as Figure 1As shown, the intake muffler 10 further includes an outlet pipe 500. The outlet pipe 500 has a third flow channel and a fourth flow channel located outside the third flow channel. Both the third flow channel and the fourth flow channel communicate with the second cavity 202b through the air outlet 206. The setting of the outlet pipe 500 is very convenient for discharging the refrigerant from the intake muffler 10. At the same time, the outlet pipe 500 including the third flow channel and the fourth flow channel is more conducive to taking into account both noise and energy consumption, and can achieve the effect of having a high energy efficiency ratio while reducing noise.

[0067] In this embodiment, the outlet pipe 500 is inserted through the air outlet 206, and one end of the outlet pipe 500 close to the partition assembly 300 extends into the second cavity 202b. In this way, it is very convenient for the outlet pipe 500 to communicate with the second cavity 202b through the air outlet 206. It can be understood that in other embodiments, one end of the outlet pipe 500 close to the partition assembly 300 may not extend into the second cavity 202b, but be received in the air outlet 206. It should be noted that in this embodiment, the outer wall of the outlet pipe 500 is sealingly connected to the inner wall of the air outlet 206. For example, the outlet pipe 500 and the air outlet 206 are in interference fit.

[0068] In this embodiment, the design of the third flow channel is substantially the same as that of the above-mentioned first flow channel 302, and the design of the fourth flow channel is substantially the same as that of the above-mentioned second flow channel 304, which will not be elaborated here. For example, the number of the third flow channels is one, and the cross-section of the third flow channel is circular; the number of the fourth flow channels is multiple, and the multiple fourth flow channels are arranged at intervals and surround the third flow channel; the multiple fourth flow channels are arranged at equal intervals; the cross-section of the fourth flow channel can be circular, arc-shaped or irregular.

[0069] In this embodiment, the inlet pipe 400 is a straight pipe, and the outlet pipe 500 is also a straight pipe. It can be understood that in other embodiments, at least one of the inlet pipe 400 and the outlet pipe 500 may be a bent pipe.

[0070] In this embodiment, as Figure 1 and Figure 2As shown, the first cavity 202a, the partition component 300, and the second cavity 202b are arranged along the first direction. The housing 200 includes a first housing portion 210 and a second housing portion 220. The first housing portion 210 is docked with the second housing portion 220 in the second direction and encloses a sound-absorbing cavity 202. The second direction intersects the first direction. Specifically, in this embodiment, the second direction is perpendicular to the first direction. More specifically, in this embodiment, the first direction is the up-down direction, and the second direction is the left-right direction. The housing 200 includes the left-right arranged first housing portion 210 and the second housing portion 220, that is, the above-mentioned intake muffler 10 is a left-right split intake muffler. The housing 200 includes the left-right arranged first housing portion 210 and the second housing portion 220, which is not only very convenient for manufacturing the housing 200, but also very convenient for arranging the partition component 300 in the housing 200. For example, the partition component 300 can be integrally formed with the first housing portion 210 or the second housing portion 220.

[0071] In this embodiment, both the air inlet 204 and the air outlet 206 are located on the second housing portion 220.
