The present disclosure is further described in detail below with reference to the accompanying drawings.
A silent structure and a mobile air conditioner are provided in one embodiment of the present disclosure.
As shown in
The soundproof chamber 2 and the connecting cylinder 1 wrap around the periphery of a compressor 6 to make the compressor 6 placed in the accommodation space and the soundproof space, and the soundproof chamber 2 completely seals and isolates the compressor 6 from the outside to make noise generated by the compressor 6 cannot be transmitted to the outside, thus solving the problem that the noise reduction effect of the mobile air conditioner in the prior art is not ideal.
Specifically, the soundproof chamber 2 is silicone material. The soundproof chamber 2 includes an extension portion 21 and a stretch-resistant portion 22. The stretch-resistant portion 22 is arranged at one side of the extension portion 21 near the connecting cylinder 1, and is arranged around the periphery of extension portion 21. The connecting cylinder 1 is wrapped by the stretch-resistant portion 22.
The soundproof space includes a first capacity space and a second capacity space. The first capacity space is formed inside the extension portion 21 and the second capacity space is formed inside the stretch-resistant portion 22. The first capacity space is connected with the second capacity space.
Specifically, the soundproof chamber 2 is made of good heat-resistant silicone material. Because silicone has good sound absorption performance and high temperature resistance, so the silicone soundproof chamber can have good performance to isolate the noise generated by the compressor 6 inside the soundproof space and the accommodation space to play a good sound insulation effect. Moreover, if the mobile air conditioner has a short circuit or other sudden situations to produce a fire source, the silicone soundproof chamber can isolate the compressor 6 from the outside environment, and to a certain extent protect the compressor 6 from the external fire source or protect the outside environment from the fire source produced by the compressor 6 inside the soundproof chamber 2.
In order to realize the soundproof chamber 2 completely seals and isolates the compressor 6 from the outside environment to ensure the noise reduction effect of the soundproof chamber 2, to achieve a better soundproof effect, the extension portion 21 and the stretch-resistant portion 22 are integrally formed.
The extension portion 21 is generally cylindrical. One end of the extension portion 21 is sealed, and the other end is arranged with an opening to connect the first capacity space with the outside environment. The stretch-resistant portion 22 is arranged at the one end of the extension portion 21 arranged with the opening. The shape of the stretch-resistant portion 22 is an overall ring similar to the shape of the extension portion 21. The stretch-resistant portion 22 is arranged at the periphery of the extension portion 21, and one end of the stretch-resistant portion 22 is arranged at the periphery of the extension portion 21 and the other end extends in the direction away from the extension portion 21. One end of the stretch-resistant portion 22 arranged at the periphery of the extension portion 21 is connected to the end part of the extension portion 21. Because there is a distance between the one end of the stretch-resistant portion 22 arranged at the periphery of the extension portion 21 and the end part of the extension portion 21, an hourglass-shaped fold structure tends toward the extension portion 21 is formed between the stretch-resistant portion 22 and the extension portion 21.
When the soundproof chamber 2 is impacted, the fold structure between the stretch-resistant portion 22 and the extension portion 21 can be partially deformed to make the soundproof chamber 2 a function of buffer and shock absorption, thereby preventing the compressor 6 from damaging the soundproof chamber 2 or other parts inside the soundproof chamber 2 during the process of transportation and use of mobile air conditioners.
A sealing hoop is arranged at the periphery of a connection position of the soundproof chamber 2 and the connecting cylinder 1.
Specifically, the overall shape of the connecting cylinder 1 is cylindrical, and two ends of the connecting cylinder 1 are connected with the outside environment. The connecting cylinder 1 includes a covering portion 11 and a connecting base 12. The covering portion 11 is arranged on the connecting base 12.
The accommodation space includes a first accommodation space and a second accommodation space. The first accommodation space is formed inside the covering portion 11 and the second accommodation space is formed inside the connecting base 12. The first accommodation space is connected with the second accommodation space and the first accommodation space is connected with the second capacity space.
Since the soundproof chamber 2 is silicone material, the soundproof chamber 2 is elastic to some extent. Relying on its own elasticity, the stretch-resistant portion 22 can wrap around the periphery of the covering portion 11 to realize an interference fit of the covering portion 11 and the tensile portion 22, thereby the soundproof chamber 2 covers the connecting cylinder 1.
The stretch-resistant portion 22 wrap around the periphery of the covering portion 11. Relying on its own elasticity, the stretch-resistant portion 22 tightly connects with the covering portion 11, enhances the airtightness of the space inside the soundproof chamber 2, and improves the overall soundproof effect.
A sealing groove 221 is arranged on the stretch-resistant portion 22. The sealing groove 221 is an annular groove with the head and tail connection and is arranged at the connecting position between the stretch-resistant portion 22 and the covering portion 11.
The sealing hoop is arranged inside the sealing groove 221. A head and a tail of the sealing hoop are detachable connected for tightening an overlap part between the stretch-resistant portion 22 and the covering portion 11, preventing the stretch-resistant portion 22 from loosening from the covering portion 11. Under the tightening function of the sealing hoop, the airtightness of the connection position between the stretch-resistant portion 22 and the covering portion 11 is further increased.
The sealing cover 3 is silicone material 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 at the periphery of the cover body 31.
Specifically, an outer diameter of the cover body 31 is less than or equal to an aperture of a pipeline connecting hole 211; outer diameters of the first abutting portion 32 and the second abutting portion 33 are greater than the aperture of the pipeline connecting hole 211; and a distance between the first abutting portion 32 and the second abutting portion 33 is equal to a hole depth value of the pipeline connecting hole 211.
Specifically, the pipeline connecting hole 211 is arranged at the top of the extension portion 21, and the top of the extension portion 21 is one end of the extension portion 21 deviating from the stretch-resistant portion 22.
The overall shape of the cover body 31 is cylindrical, and the shapes of the first abutting portion 32 and the second abutting portion 33 are circular. Respectively, the first abutting portion 32 and the second abutting portion 33 are arranged at the periphery of the cover body 31. The first abutting portion 32, the second abutting portion 33, and the cover body 31 are coaxial arranged. In one embodiment, in order to provide the soundproof chamber 2 with good airtightness, the aperture of the cover body 31 is slightly smaller than that of the pipeline connecting hole 211, and the outer diameters of the first abutting portion 32 and the second abutting portion 33 are larger than the aperture of the pipeline connecting hole 211. Since the sealing cover 3 is a silicone sealing cover and has ductibility to some extent, the second abutting portion 33 can be folded to bring the second abutting portion 33 into the soundproof chamber 2 through the pipeline connecting hole 211, and after entering the soundproof chamber 2, the second abutting portion 33 can become back to the 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 of the pipeline connecting hole 211 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 connecting hole 211, the second abutting portion 33 abuts against the inner wall of the top of the extension portion 21 after extending into the interior of the soundproof chamber 2 to prevent the noise inside the soundproof chamber 2 from penetrating to the outside environment through the gap between the sealing cover 3 and the pipeline connecting hole 211. Meanwhile, the first abutting portion 32 at the other side of the cover body 31 is connected with the outer surface of the top of the extension portion 21 to improve the overall airtightness of the soundproof chamber 2.
In a better embodiment, a fastener 212 is arranged protruding from the extension portion 21 around the surrounding position of the pipeline connecting hole 211. The fastener 212 is hollow and cylindrical and its inner hole is formed by the pipeline connecting hole 211 extending upward, since the first abutting portion 32 abuts against the end part of the fastener 212.
A sealing hoop is arranged at the periphery of the fastener 212, which is used to tighten the fastener 212 so that the cover body 31 inside the pipeline connecting hole 211 closely contacts the hole wall of the pipeline connecting hole 211, improving the airtightness of the soundproof chamber 2.
A mobile air conditioner is provided in one embodiment of the present disclosure, and the mobile air conditioner includes the silent structure as described above.

A plurality of second connection protrusion 511, with same quantity as first connection protrusions 121, are arranged on the mounting fence 51, and the threaded through holes are arranged on the plurality of second connection protrusion 511. After the connecting base 12 is mounting to the mounting fence 51, the plurality of first connection protrusions 121 cooperates with the plurality of second connection protrusions 511, one by one, and a threaded bolt is screwed in between each first connection protrusion 121 and the corresponding second connection protrusion 511 to achieve the connection between the connecting cylinder 1 and the mounting chassis 5. Moreover, the tight connection between the connecting cylinder 1 and the mounting chassis 5 through the plurality of first connection protrusions 121 and the second connecting protrusions 511 improves the overall airtightness. Meanwhile, the connecting cylinder 1 and the mounting chassis 5 can be detachable connected, so that the connecting cylinder 1 can be removed at any time for maintenance or replacement.
The mobile air conditioner further includes a connecting pipe 7.
An insert hole 36 is arranged on the sealing cover 3 and communicates the third capacity space and the soundproof space.
An insert pipe 61 is arranged on the compressor 6. The insert pipe 61 extends through the insert hole 36 into the third capacity space, and the connecting pipe 7 is connected to the insert pipe 61.
Specifically, the soundproof chamber 2 is arranged with two pipeline connecting holes 211, and two corresponding sealing covers 3.
The two sealing covers 3 include a drainage sealing cover 34 for drainage and a water-inlet sealing cover 35 for water intake, respectively. The size of the water-inlet sealing cover 35 is greater than the size of the drainage sealing cover 34.
The water-inlet sealing cover 35 is arranged with a first disassembly protrusion 351, and the first disassembly protrusion 351 is arranged at one end of the first abutting portion 32 deviating from the cover body 31. The water-inlet sealing cover 35 may be removed from the pipeline connecting hole 211 by holding the first disassembly protrusion 351 tightly.
The drainage sealing cover 34 is arranged with a second disassembly protrusion 341, and the second disassembly protrusion 341 is arranged at one end of the first abutting portion 32 deviating from the cover body 31. The shape of second disassembly protrusion 341 is a cylinder. The second disassembly protrusion 341 and the first abutting portion 32 are coaxial arranged. The second disassembly protrusion 341 includes a holding portion 3411 and a supporting portion 3412. One end of the holding portion 3411 is connected to the supporting portion 3412, and another end of the holding portion 3411 is connected to the first abutting portion 32. The outer diameter of the supporting portion 3412 is greater than the outer diameter of the holding portion 3411. The drainage sealing cover 34 may be removed from the pipeline connecting hole 211 by holding the holding portion 3411 tightly and under the support of the support portion 3412. Each sealing cover 3 is arranged with an insert hole 36, and two insert holes 36 are arranged facing the inlet and drain of the compressor 6 inside the soundproof chamber 2. Among them, the insert hole 36 on the water-inlet sealing cover 35 is arranged close to the first disassembly protrusion 351, and the insert hole 36 on the drainage sealing cover 34 passes through the second disassembly protrusion 341.
Two insert pipes 61 are arranged and each of which is configured at the drain outlet and water inlet of the compressor 6, respectively. Each of the two insert pipes 61 passes through the corresponding insert hole 36 and penetrates into the third capacity space.
The connecting pipe 7 includes a drain pipe and a water-inlet pipe. The drain pipe is connected to the one insert pipe 61 with the drain and the water-inlet pipe is connected to the another insert pipe 61 with the inlet.
The connecting pipe 7 and the two insert pipes 61 are both metal pipes. In order to improve the airtightness of the connecting pipe 7 connecting to the two insert pipes 61 and improve the sound insulation efficiency of the whole mobile air conditioner, the connecting pipe 7 and the two insert pipes 61 are welded for connection.
In a better embodiment, the insert pipes 61 and the insert holes 36 are in an interference fit to ensure the overall tightness of the soundproof chamber 2 and prevent the noise produced by the compressor 6 passing through the gap between the insert pipes 61 and the insert holes 36 from being transmitted outside.
A gap is formed between the compressor 6 and the soundproof space; a gap is formed between the compressor 6 and the accommodation space.
The compressor 6 arranged inside the soundproof chamber 2 and the connecting cylinder 1 does not directly contact with the soundproof chamber 2 and the connecting cylinder 1, causing a gap between the compressor 6 and the soundproof chamber 2 and a gap between the compressor 6 and the connecting cylinder 1, thus avoiding the direct contact between the compressor 6 and soundproof chamber 2 and the direct contact between the compressor 6 the connecting cylinder 1, thus avoiding the noise generated by that the vibration generated by compressor 6 during operation is transmitted to the outside through solid transmission. Moreover, the indirect contact between the compressor 6 and the soundproof chamber 2 and the indirect contact between the compressor 6 and the connecting cylinder 1 can avoid the connection between the soundproof chamber 2 and the connection cylinder 1 loose due to the long time of vibration when the vibration generated during the operation of the compressor 6 transmitting to the soundproof chamber 2 and the connecting cylinder 1.
In summary, a silent structure includes a connecting cylinder 1, a soundproof chamber 2, and a sealing cover 3; an accommodation space is formed inside the connecting cylinder 1, and one end of the connecting cylinder 1 is arranged on a mounting chassis 5 of the mobile air conditioner; another end of the connecting cylinder 1 is covered by the soundproof chamber 2; a soundproof space is formed inside the soundproof chamber 2 and is connected with the accommodation space; a pipeline connecting hole 211 is arranged on the soundproof chamber 2; the sealing cover 3 is arranged on the pipeline connecting hole 211.
The soundproof chamber 2 and the connecting cylinder 1 wrap around the periphery of the compressor 6 to make the compressor 6 placed inside the accommodation space and the soundproof space, and the soundproof chamber 2 completely seals and isolates the compressor 6 from the outside to make noise generated by the compressor 6 cannot be transmitted to the outside, thus solving the problem that the noise reduction effect of the mobile air conditioner in the prior art is not ideal.
