[0002] Transmission noise often occurs in the indoor unit of an air conditioner. To solve the transmission noise problem, the existing technology installs a baffle on the outlet pipe of the liquid reservoir to improve the transmission noise. However, for the transmission noise in the 400-800Hz frequency band generated during the operation of the refrigeration system, even with the installation of the existing baffle, the transmission loss of the transmission noise in this frequency band in the liquid reservoir is still very small and cannot be weakened, making the transmission noise problem of the liquid reservoir still serious.

[0027] In order to make the purpose, advantages and features of the present invention more clear, the following Figures 1 to 4 The silencer, liquid reservoir, and compressor proposed in the present invention are described in further detail. It should be noted that the accompanying drawings are simplified and not precisely proportioned, and are intended only to facilitate and clearly illustrate the embodiments of the present invention.

In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0029] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] The core idea of ​​the present invention is to provide a silencer, a liquid reservoir and a compressor to increase the transmission loss of the transmitted sound in the liquid reservoir, especially to increase the transmission loss of the transmitted sound in the frequency band of 400Hz-800Hz in the liquid reservoir, thereby effectively improving the transmission sound problem caused by the liquid reservoir.

[0031] To realize the above idea, the present invention provides a silencer device, which is applied to the liquid storage device. Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the planar structure of the muffler provided by the present invention is shown schematically; Figure 2 It is given schematically Figure 1 The cross-sectional view of the silencer along the AA direction. Figure 1 and Figure 2 As shown, the silencer device includes an annular partition 200, a first hollow sleeve 210 provided on the partition 200 and at least one through hole 230 passing through the partition 200; the inner cavity of the first hollow sleeve 210 is coaxially arranged with the partition 200, and the outer wall of the first hollow sleeve 210 is arranged along the inner circumference of the partition 200, and the first hollow sleeve 210 and the partition 200 are both used to be sleeved on the air outlet pipe 120 of the liquid reservoir; the outer circle of the partition 200 is used to be connected to the inner wall of the cylinder 100 of the liquid reservoir. Thus, through the structure of the first hollow sleeve 210 and the partition 200, the silencer can be mounted on the outlet pipe 120 of the liquid reservoir, and the silencer can be connected to the inner wall of the cylinder 100 of the liquid reservoir through the outer circumference of the partition 200. This not only effectively and firmly fixes the silencer between the cylinder 100 of the liquid reservoir and the outlet pipe 120, but also more effectively ensures the airtightness between the silencer, the cylinder 100, and the outlet pipe 120. At the same time, the liquid refrigerant in the liquid reservoir can also flow into the bottom of the cylinder 100 of the liquid reservoir through the through hole 230. The structure of the through hole 230, the partition 200, the first hollow sleeve 210, and the liquid reservoir can increase the transmission loss of transmitted sound of a specific frequency through the silencer, thereby effectively weakening or eliminating the transmitted sound. In addition, the silencer provided by the present invention can significantly improve the transmission loss of the transmitted sound in the frequency band of 400Hz-800Hz, thereby effectively improving the problem of transmitted sound caused by the liquid reservoir.

[0032] It should be noted that the silencer is preferably installed in the liquid reservoir by welding, that is, the partition 200 and the air outlet pipe 120, the first hollow sleeve 210 and the air outlet pipe 120, and the partition 200 and the inner wall of the cylinder 100 of the liquid reservoir are all connected by welding; in some other embodiments, the connection method between the partition 200 and the air outlet pipe 120, the first hollow sleeve 210 and the air outlet pipe 120, and the partition 200 and the inner wall of the cylinder 100 of the liquid reservoir can also be specific bonding, clamping or one-piece molding.

[0033] The following combination Figure 1 and Figure 2 The silencer provided by the present invention is described in detail:

[0034] Preferably, the silencer device further includes a second hollow sleeve 220 disposed along the outer circumference of the partition plate 200. The second hollow sleeve 220 is located on a side of the partition plate 200 facing away from the first hollow sleeve 210. The second hollow sleeve 220 is configured to connect to the inner wall of the liquid reservoir body 100. Because the second hollow sleeve 220 has a larger contact surface, the second hollow sleeve 220 can more effectively connect the silencer device to the body 100, thereby ensuring reliable installation of the silencer device.

[0035] Preferably, the partition 200 is further provided with a through-hole column 240 corresponding to the through-hole 230, and the through-hole 230 is provided along the axial direction of the through-hole column 240. Since a cavity can be formed between the muffler, the cylinder 100, and the air outlet pipe 120 when the muffler is installed in the liquid reservoir, the provision of the through-hole column 240 can effectively improve the structure within the cavity, and the through-hole 230 passing through the through-hole column 240 is equivalent to a constricted structure, thereby allowing the transmitted sound to be reflected multiple times in the cavity, making it difficult to transmit out. In particular, the transmission loss of the transmitted sound in the frequency band of 400Hz-800Hz can be increased, thereby achieving the purpose of improving the transmitted sound in the liquid reservoir.

[0036] It should be noted that, since a accommodating space is formed between the second hollow sleeve 220 and the partition 200, and the through-hole column 240 is located in the accommodating space, in some other embodiments, at least one partition 200 can also be arranged in the accommodating space, and the outer circle of the at least one partition 200 can be connected to the second hollow sleeve 220, and the at least one partition 200 is connected in sequence to the partition 200 with the first hollow sleeve 210 through the through-hole column 240, and the inner circle of the at least one partition 200 is also used to be connected to the air outlet pipe 120 of the liquid reservoir. When such a silencer is installed in the cylinder 100 of the liquid reservoir, a cavity can be formed between the two adjacent partitions 200, the air outlet pipe 120 of the liquid reservoir and the second hollow sleeve 220.

[0037] Preferably, the through holes 230 are multiple and symmetrically arranged along the circumference of the partition 200. Specifically, four through holes 230 are symmetrically arranged along the circumference of two layers of the partition 200 to implement the silencer provided by the present invention. This effectively ensures that the silencer significantly improves the transmission loss of transmitted sound and weakens the transmitted sound within the reservoir, while also effectively simplifying the manufacturing process and saving costs.

[0038] Preferably, the diameter d of the through hole 230 is 0.5 mm to 20 mm. This configuration allows the through hole 230 to effectively pass liquid refrigerant while also cooperating with the partition 200 and the through-hole column 240 to effectively attenuate transmitted sound of specific frequencies. It should be noted that the through hole is preferably a circular hole. In other embodiments, the through hole may also have a polygonal or irregular shape.

[0039] Preferably, an axial height h1 of the first hollow sleeve 210 relative to the partition 200 is greater than 3 mm, and an axial height h2 of the first hollow sleeve 210 relative to the partition 200 is the height by which the first hollow sleeve 210 protrudes from the partition 200. This facilitates a more stable and reliable connection between the silencer device and the air outlet pipe 120 of the liquid reservoir.

[0040] Preferably, an axial height h2 of the through-hole column 240 relative to the partition 200 is 2 mm to 20 mm, where the axial height h2 of the through-hole column 240 relative to the partition 200 is the height by which the through-hole column 240 protrudes from the partition 200. Since further lengthening of the through-hole column exceeding 20 mm has little effect on increasing the transmission loss of transmitted sound, controlling the length of the through-hole column 240 can both structurally eliminate transmitted sound of specific frequencies and effectively control costs.

[0041] More preferably, the axial height h2 of the through-hole column 240 relative to the partition 200 is 5 mm to 20 mm. Therefore, the through-hole column 240 with a height of 5 mm to 20 mm can better ensure the elimination of the transmitted sound of a specific frequency in terms of structure, and can more effectively cooperate with the structure of the partition 200.

[0042] Preferably, the first hollow sleeve 210 is disposed at an end of the partition 200 that is close to the intake pipe 110 of the liquid reservoir, and the through-hole column 240 is disposed at an end of the partition 200 that is away from the intake pipe 110 of the liquid reservoir. This arrangement facilitates the formation of a cavity structure within the liquid reservoir, allowing the through-hole column 240 to be located in the lower cavity formed after the liquid reservoir is divided by the partition 200, thereby further facilitating reduced transmission loss of transmitted sound.

[0043] Preferably, the first hollow sleeve 210, the partition plate 200, and the through-hole column 240 are formed into an integrally molded structure. Thus, the integrally molded structure is more conducive to the manufacture and installation of the silencer. In addition, more specifically, the second hollow sleeve 220, the first hollow sleeve 210, the partition plate 200, and the through-hole column 240 are formed into an integrally molded structure.

[0044] In order to realize the above idea, the present invention also provides a liquid storage device, please refer to Figure 3 and Figure 4 ,in, Figure 3 The structural diagram of the liquid reservoir provided by the present invention is schematically given; Figure 4 The waveform diagram of the transmission loss of the liquid reservoir provided by the present invention and the existing liquid reservoir as a function of frequency is schematically shown. Figure 3 As shown, the liquid reservoir includes at least one silencer as described above, a cylinder 100, an air intake pipe 110 and an air outlet pipe 120; one end of the air intake pipe 110 protrudes from the cylinder 100, and the other end of the air intake pipe 110 is fixed to the cylinder 100; the air outlet pipe 120 is arranged in the cylinder 100 along the axial direction of the cylinder 100, and the end of the air outlet pipe 120 away from the air intake pipe 110 is fixed to the cylinder 100; the silencer is sleeved on the air outlet pipe 120 and is connected to the inner wall of the cylinder 100. Therefore, the liquid reservoir provided by the present invention not only includes all the advantages of the silencer as described above, but also can achieve functional superposition by arranging multiple silencers, so as to more effectively weaken the transmitted sound. And from Figure 4It can be seen that when the frequency band is between 440Hz-720Hz, the transmission loss of the transmitted sound by the silencer device inside the liquid reservoir provided by the present invention is significantly greater than the transmission loss of the transmitted sound by the structure inside the existing liquid reservoir. Therefore, the liquid reservoir provided by the present invention can significantly increase the transmission loss of the transmitted sound and effectively weaken the transmitted sound in the frequency band of 400Hz-800Hz, especially the transmitted sound in the frequency band of 440Hz-720Hz.

[0045] It should be noted that, in some other embodiments, when the liquid reservoir includes at least two silencer devices, the connection between the at least two silencer devices can be an integrated structure, that is, the through hole 230, the first hollow sleeve 210, the second hollow sleeve 220 and the through hole column 240 of each silencer device are connected to the corresponding structures of the adjacent silencer device.

[0046] Preferably, the liquid reservoir further includes a filter holder 130 disposed within the barrel 100. The outer periphery of the filter holder 130 is connected to the inner wall of the barrel 100, and the filter holder 130 is provided with a plurality of guide holes. Thus, the filter holder 130 can support the filter to facilitate filtering the refrigerant drawn in from the intake pipe 110.

[0047] Specifically, the filter bracket 130 includes a connected support plate and a protrusion 131. The protrusion 131 is arranged on the side of the filter bracket 130 close to the intake pipe 110, and the protrusion 131 is used to guide the refrigerant sucked from the intake pipe 110; the multiple guide holes are arranged on the support plate, and the multiple guide holes are centrally symmetrically distributed along the circumference of the filter bracket 130, and each of the guide holes is provided with a guide plate 132 matching it, and the guide plate 132 is arranged away from the side of the filter bracket 130 close to the intake pipe 110.

[0048] To realize the above idea, the present invention further provides a compressor including the liquid reservoir as described above. Therefore, the liquid reservoir provided by the present invention includes all the advantages of the liquid reservoir as described above, which will not be described in detail here.

At the same time, the liquid refrigerant in the liquid reservoir can also flow into the bottom of the cylinder of the liquid reservoir through the through hole; and the structure of the through hole, the partition, the first hollow sleeve and the liquid reservoir can increase the transmission loss of the transmission sound of a specific frequency in the liquid reservoir, thereby effectively weakening or eliminating the transmission sound. In addition, the silencer provided by the present invention can significantly improve the transmission loss of the transmission sound in the frequency band of 400Hz-800Hz, thereby effectively improving the transmission sound problem caused by the liquid reservoir.
