[0044] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] The present application is further described in detail below in conjunction with the accompanying drawings.

[0046] The embodiments of the present application disclose a silent structure and a mobile air conditioner.

[0047] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a soundproof structure includes a connecting tube 1, a soundproof chamber 2 and a sealing cover 3. A accommodating space is formed inside the connecting tube 1, and one end of the connecting tube 1 is arranged on the mounting chassis 5 of the mobile air conditioner; the soundproof chamber 2 is covered at the other end of the connecting tube 1, and a soundproof space is formed inside the soundproof chamber 2, and the soundproof space is connected to the accommodating space; a pipeline connecting hole 211 is arranged on the soundproof chamber 2; and the sealing cover 3 is arranged on the pipeline connecting hole 211.

[0048] The soundproof chamber 2 and the connecting tube 1 are wrapped around the outer periphery of the compressor 6, so that the compression components are placed in the accommodating space and the silent space. The soundproof chamber 2 completely seals and isolates the compressor 6 from the outside world, so that the noise generated by the compressor 6 cannot be transmitted to the outside world, solving the problem of unsatisfactory noise reduction effect of mobile air conditioners in the prior art.

[0049] Specifically, the soundproof chamber 2 is a silicone soundproof chamber. The soundproof chamber 2 includes an extension portion 21 and an anti-stretching portion 22, wherein the anti-stretching portion 22 is arranged on a side of the extension portion 21 close to the connecting tube 1, and the anti-stretching portion 22 is arranged around the outer periphery of the extension portion 21, and the anti-stretching portion 22 is covered on the connecting tube 1.

[0050] The silent space includes a first accommodating space and a second accommodating space. The first accommodating space is formed inside the extension portion 21 , the second accommodating space is formed inside the anti-stretching portion 22 , and the first accommodating space is communicated with the second accommodating space.

[0051] Specifically, the soundproof chamber 2 is made of high-temperature resistant silicone material. Since silicone has good sound absorption and high-temperature resistance, the use of a silicone soundproof chamber can well isolate the noise generated by the compressor 6 in the silent space and the accommodation space, achieving a good sound insulation effect. If a short circuit or other emergency occurs in the mobile air conditioner and a fire source is generated, the silicone soundproof chamber can isolate the compressor 6 from the outside world, and to a certain extent protect the compressor 6 from the external fire source or the outside world from the fire source generated by the compressor 6 inside the soundproof chamber 2.

[0052] In order to achieve that the soundproof chamber 2 completely seals and isolates the compressor 6 from the outside world and ensures the soundproofing effect of the soundproof chamber 2 to achieve a better soundproofing effect, the extension portion 21 and the anti-stretching portion 22 are integrally formed.

[0053] The shape of the extension part 21 is a cylindrical tube as a whole. One end of the extension part 21 is sealed, and the other end is provided with an opening to connect the first accommodating space with the outside. The anti-stretching part 22 is provided at the end of the extension part 21 provided with an opening. The shape of the anti-stretching part 22 is a ring-shaped shape similar to that of the extension part 21 as a whole. The anti-stretching part 22 is provided at the periphery of the extension part. One end of the anti-stretching part 22 is located at the periphery of the extension part, and the other end extends in a direction away from the extension part. One end of the anti-stretching part 22 located at the periphery of the extension part is connected to the end of the extension part. Since there is a certain distance between the end of the anti-stretching part 22 located at the periphery of the extension part and the end of the extension part, an hourglass-shaped fold inclined toward the extension part is formed between the anti-stretching part 22 and the extension part.

[0054] The pleated design between the anti-stretching part 22 and the extension part allows the sound insulation chamber 2 to undergo a certain deformation when impacted, so that the sound insulation chamber 2 has a buffering and shock-absorbing effect, thereby preventing the compressor 6 of the mobile air conditioner from damaging the sound insulation chamber 2 or other components inside the mobile air conditioner during transportation and use.

[0055] A sealing hoop is provided on the outer periphery of the connection between the soundproof chamber 2 and the connecting tube 1 .

[0056] Specifically, the overall shape of the connecting tube 1 is a cylindrical tube, and both ends of the connecting tube 1 are connected to the outside. The connecting tube 1 includes a covering portion 11 and a connecting base 12, and the covering portion 11 is arranged on the connecting base 12.

[0057] The accommodating space includes a first accommodating space and a second accommodating space. The first accommodating space is formed in the covering portion 11 , and the second accommodating space is formed in the connecting base 12 . The first accommodating space and the second accommodating space are connected.

[0058] Since the soundproofing chamber 2 is a silicone soundproofing chamber, it has a certain elasticity. The anti-stretching part 22 can rely on its own elasticity to wrap around the outer periphery of the covering part 11, so as to achieve an interference fit between the covering part 11 and the anti-stretching part 22, thereby covering the soundproofing chamber 2 on the connecting tube 1.

[0059] The anti-stretching part 22 is wrapped around the outer periphery of the covering part 11. Relying on the elasticity of the anti-stretching part 22 itself, the anti-stretching part 22 is tightly connected to the covering part 11, thereby enhancing the airtightness of the space inside the soundproof chamber 2 and improving the overall soundproofing effect.

[0060] The anti-stretching portion 22 is provided with a sealing groove 221 . The sealing groove 221 is an annular groove connected end to end. The sealing groove 221 is located at the connection position between the anti-stretching portion 22 and the covering portion 11 .

[0061] The sealing hoop is arranged in the sealing groove 221, and the sealing hoop is detachably connected at both ends, and is used to tighten the overlapping part of the anti-stretching part 22 and the covering part 11 to prevent the anti-stretching part 22 from loosening from the covering part 11. Under the tightening action of the sealing hoop, the airtightness of the connection between the anti-stretching part 22 and the covering part 11 is further improved.

[0062] The sealing cover 3 is a silicone sealing cover, and includes a cover body 31 , a first abutting portion 32 and a second abutting portion 33 . The first abutting portion 32 and the second abutting portion 33 are arranged on the outer periphery of the cover body 31 .

[0063] Among them, the outer diameter of the cover body 31 is less than or equal to the aperture of the pipeline connecting hole 211, the outer diameters of the first abutment portion 32 and the second abutment portion 33 are larger than the aperture of the pipeline connecting hole 211, and the distance between the first abutment portion 32 and the second abutment portion 33 is equal to the hole depth value of the pipeline connecting hole 211.

[0064] Specifically, the pipeline connection hole 211 is disposed at the top of the extension portion 21 , wherein the top of the extension portion 21 is an end of the extension portion 21 away from the anti-stretching portion 22 .

[0065] The overall shape of the cover body 31 is cylindrical, and the shape of the first abutting portion 32 and the second abutting portion 33 are both annular, and the first abutting portion 32 and the second abutting portion 33 are respectively arranged on the outer periphery of the cover body 31, and the first abutting portion 32, the second abutting portion 33 and the cover body 31 are coaxially arranged. In this embodiment, in order to make the soundproof chamber 2 have good airtightness, the aperture size of the cover body 31 is slightly smaller than the aperture size of the pipeline connection hole 211, and the outer diameter of the first abutting portion 32 and the outer diameter of the second abutting portion 33 are both larger than the aperture size of the pipeline connection portion. Since the sealing cover 3 is a silicone sealing cover, it has a certain degree of ductility. The second abutting portion 33 can be folded, etc., so that the second abutting portion 33 passes through the pipeline connection hole 211 and enters the interior of the soundproof chamber 2. After entering the interior of the soundproof chamber 2, the second abutting portion 33 returns to its original state under the action of the elastic restoring force. Since the outer diameter of the second abutting portion 33 is larger than the aperture size of the pipeline connection portion, and the distance between the first abutting portion 32 and the second abutting portion 33 is equal to the hole depth value of the pipeline connection hole 211, the second abutting portion 33 will abut against the top inner wall of the extension portion 21 after extending into the interior of the soundproof chamber 2, thereby preventing the sound in the soundproof chamber 2 from passing through the gap between the sealing cover 3 and the pipeline connection hole 211 to the outside. The first abutting portion 32 on the other side of the cover body 31 will also abut against the top outer surface of the extension portion 21, thereby improving the overall airtightness of the soundproof chamber 2.

[0066] In a preferred embodiment, fasteners 212 protrude from the extension portion 21 around the pipe connection hole 211. The fastener 212 is hollow cylindrical as a whole. The internal hole of the fastener 212 is formed by the upward extension of the pipe connection hole 211. The first abutment portion 32 abuts against the end of the fastener 212.

[0067] A sealing hoop is provided on the periphery of the fastener 212, and the sealing hoop on the periphery of the fastener 212 is used to tighten and fasten the fastener 212, so that the cover body 31 located in the pipeline connecting hole 211 will be tightly attached to the hole wall of the pipeline connecting hole 211, thereby improving the airtightness of the soundproof chamber 2.

[0068] This embodiment also includes a mobile air conditioner, including the above-mentioned silent structure.

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9As shown, the mobile air conditioner also includes: an air-conditioning casing 4, a mounting chassis 5 and a compressor 6, the air-conditioning casing 4 is arranged on the mounting chassis 5, and the air-conditioning casing 4 and the mounting chassis 5 form a third accommodating space; the compressor 6 is arranged on the mounting chassis 5; wherein, the connecting tube 1 and the soundproof chamber 2 are arranged on the periphery of the compressor 6, the compressor 6 is located in the accommodating space and the silent space, the connecting tube 1 is arranged on the mounting chassis 5, and the connecting tube 1 and the mounting chassis 5 are detachably connected.

[0070] Specifically, an installation area for installing the compressor 6 is provided on the installation chassis 5 , an installation fence 51 is provided at the edge of the installation area, and the compressor 6 is fixedly installed in the installation fence 51 .

[0071] After the compressor 6 is installed on the mounting chassis 5, the connecting cylinder 1 is sleeved on the outer periphery of the compressor 6, and the connecting base 12 cooperates with the mounting fence 51. A plurality of first connecting protrusions 121 arranged at intervals are arranged around the outer periphery of the connecting base 12, and a threaded through hole is arranged on the first connecting protrusion 121. The mounting fence 51 is provided with the same number of second connecting protrusions 511 as the first connecting protrusions 121, and the second connecting protrusions 511 are also provided with a threaded through hole. After the connecting base 12 is set on the mounting fence 51, the first connecting protrusions 121 and the second connecting protrusions 511 are matched one by one, and then a bolt is screwed in between each first connecting protrusion 121 and its corresponding second connecting protrusion 511 to realize the connection between the connecting cylinder 1 and the mounting chassis 5, and the tight connection between the connecting cylinder 1 and the mounting chassis 5 is improved by the plurality of first connecting protrusions 121 and the second connecting protrusions 511. The connection between the connecting cylinder 1 and the mounting chassis 5 is detachable, which is convenient for the removal of the connecting cylinder 1 at any time for maintenance or replacement.

[0072] The mobile air conditioner also includes a connecting pipe 7;

[0073] The sealing cover 3 is provided with an insertion hole 36, and the insertion hole 36 communicates with the silent space and the third accommodating space;

[0074] The compressor 6 is provided with an insertion tube 61 . The insertion tube 61 passes through the insertion hole 36 and extends into the third accommodating space. The connecting tube 7 is connected to the insertion tube 61 .

[0075] Specifically, two pipeline connection holes 211 are provided on the sound insulation cover, and two corresponding sealing covers 3 are also provided.

[0076] The two sealing covers 3 are respectively a drainage sealing cover 34 for drainage and a water inlet sealing cover 35 for water inlet. The size of the water inlet sealing cover 35 is larger than that of the drainage sealing cover 34.

[0077] The water inlet sealing cover 35 has a first disassembly protrusion 351 disposed on one end of the first abutting portion 32 away from the cover body 31. The water inlet sealing cover 35 can be removed from the pipeline connection hole 211 by gripping the disassembly protrusion 351.

[0078] On the drainage sealing cover 34, a second disassembly protrusion 341 is provided at one end of the first abutting portion 32 away from the cover body 31. The overall shape of the second disassembly protrusion 341 is a column, and the second disassembly protrusion 341 is coaxially arranged with the first abutting portion 32. The second disassembly protrusion 341 includes a gripping portion 3411 and a supporting portion 3412. One end of the gripping portion 3411 is connected to the supporting portion 3412, and the other end is connected to the first abutting portion 32. The outer diameter of the supporting portion 3412 is larger than the outer diameter of the gripping portion 3411. The drainage sealing cover can be removed from the pipeline connection hole 211 by gripping the gripping portion 3411 and supported by the supporting portion 3412. An insertion hole 36 is provided on each sealing cover 3, and the two insertion holes 36 are respectively opposite to the water inlet and the drain outlet of the compressor 6 inside the soundproof chamber 2. The insertion hole 36 on the water inlet sealing cover 35 is arranged close to the first disassembly protrusion 351 , and the insertion hole 36 on the water discharge sealing cover 34 passes through the second disassembly protrusion 341 .

[0079] Two insertion tubes 61 are provided, and the two insertion tubes 61 are respectively provided at the water outlet and the water inlet of the compressor 6.

[0080] The connecting pipe 7 includes a drain pipe and a water inlet pipe. The drain pipe is connected to the insertion pipe 61 connected to the drain port, and the water inlet pipe is connected to the insertion pipe 61 connected to the water inlet.

[0081] The connecting pipe 7 and the inserting pipe 61 are both metal pipes. In order to improve the airtightness of the connection between the connecting pipe 7 and the inserting pipe 61 and improve the overall sound insulation performance of the mobile air conditioner, the connecting pipe 7 and the inserting pipe 61 are connected by welding.

[0082] In a preferred embodiment, the insertion tube 61 and the insertion hole 36 are interference fit, thereby ensuring the overall airtightness of the soundproof chamber 2 and preventing the noise generated by the compressor 6 from being discharged to the outside through the gap between the insertion tube 61 and the insertion hole 36.

[0083] There are gaps between the compressor 6 and the silent space and between the compressor 6 and the accommodating space.

[0084] The compressor 6 disposed in the soundproof chamber 2 and the connecting tube 1 is not in direct contact with the soundproof chamber 2 and the connecting tube 1, so that there is a gap between the compressor 6 and the soundproof chamber 2 and the connecting tube 1, thereby avoiding the vibration generated by the compressor 6 during operation from being transmitted to the outside through the solid-solid transmission due to the direct contact between the compressor 6 and the soundproof chamber 2 and the connecting tube 1, thereby generating noise. In addition, avoiding direct contact between the compressor 6 and the soundproof chamber 2 and the connecting tube 1 can avoid the vibration generated during the operation of the compressor 6 from being transmitted to the soundproof chamber 2 and the connecting tube 1, resulting in the soundproof chamber 2 and the connecting tube 1 being loosened due to long-term vibration.

[0085] In summary, a soundproofing structure includes a connecting tube 1, a soundproofing chamber 2 and a sealing cover 3. A accommodating space is formed inside the connecting tube 1, and one end of the connecting tube 1 is arranged on the chassis of the mobile air conditioner; the soundproofing chamber 2 is covered at the other end of the connecting tube 1, and a soundproofing space is formed inside the soundproofing chamber 2, and the soundproofing space is connected to the accommodating space; a pipeline connecting hole 211 is arranged on the soundproofing chamber 2; and the sealing cover 3 is arranged on the pipeline connecting hole 211.

[0086] The soundproof chamber 2 and the connecting tube 1 are wrapped around the outer periphery of the compressor 6, so that the compression components are placed in the accommodating space and the silent space. The soundproof chamber 2 completely seals and isolates the compressor 6 from the outside world, so that the noise generated by the compressor 6 cannot be transmitted to the outside world, solving the problem of unsatisfactory noise reduction effect of mobile air conditioners in the prior art.
