The specific meanings of the above terms in the embodiments of the present application can be understood by those of ordinary skill in the art according to specific situations.

The first embodiment is as follows:

as shown in fig. 1 and 2, according to a first embodiment of the present invention, a muffler is provided and is applied to a compressor and a refrigeration apparatus, so that noise is reduced and noise is reduced during a refrigerant flow process when the compressor is in a refrigeration operation. Specifically, the muffler includes a housing 10, a muffler pipe 20 and a first partition plate 30, the housing 10 has an inner cavity 11, a top wall of the housing 10 is opened with an outlet pipe opening connected with an outlet pipe 100, the outlet pipe 100 is connected to a compressor, a side wall of the housing 10 is opened with an inlet pipe opening 13 (see fig. 7 in combination), the inlet pipe opening 13 is connected with an inlet pipe 200, the inlet pipe 200 is connected to an evaporator of a refrigeration apparatus, and a gaseous refrigerant output from the evaporator flows through the muffler from the inlet pipe 200 and is delivered to the compressor from the outlet pipe 100, thereby achieving a noise reduction effect on the flow of the gaseous refrigerant in the muffler.

In this muffler, the muffler pipe 20 includes a first pipe section 21 and a second pipe section 22 arranged in an L-shape, i.e., a bent connection between the first pipe section 21 and the second pipe section 22. The first pipe section 21 communicates with the outlet pipe mouth, and the second pipe section 22 communicates with the inlet pipe mouth 13, and compared with the silencer pipe which is arranged in a serpentine shape in the silencer in the prior art, the silencer pipe 20 of the L shape of the silencer of the embodiment of the utility model has a shorter length of the on-way pipe, so that on-way resistance can be greatly reduced, and the flow efficiency of the gaseous refrigerant can be improved. Further, the first baffle 30 of the muffler is installed to the inner chamber 11 to divide the inner chamber 11 into a first chamber 111 and a second chamber 112 (see fig. 11 and 19 in combination), at least a portion of the first tube segment 21 is located in the first chamber 111, the second tube segment 22 is located in the second chamber 112, and the tube passage of the first tube segment 21 communicates with the first chamber 111 and the tube passage of the second tube segment 22 communicates with the second chamber 112. In this way, the first cavity 111 muffles the flow noise generated when the gaseous refrigerant in the first pipe section 21 flows, and the second cavity 112 muffles the flow noise generated when the gaseous refrigerant in the second pipe section 22 flows, so that the gaseous refrigerant can obtain a good muffling and noise-reducing effect in the whole process of flowing through the muffler, and the muffling performance of the muffler is improved.

By applying the silencer provided by the embodiment of the utility model, the silencing pipe 20 arranged in the inner cavity 11 of the shell is designed to be L-shaped, so that the on-way length is greatly reduced compared with a serpentine pipeline used in the prior art, the on-way length of the gaseous refrigerant flowing in the pipeline is reduced, and the on-way resistance is reduced. Thus, compared with the silencer in the prior art, when the COP is the same, the silencer in the embodiment of the utility model reduces the on-way resistance to the flow of the gaseous refrigerant, so that the energy efficiency of the refrigerant is improved, and the unit energy consumption is lower. In addition, the first partition plate 30 is assembled to form the silencing chambers, namely the first cavity 111 and the second cavity 112, corresponding to the first pipe section 21 and the second pipe section 22 of the silencing pipe 20 respectively, so that the flow of the gaseous refrigerant in the first pipe section 21 and the second pipe section 22 can be silenced in a segmented manner, the silencing and noise reducing effects are obvious, and the silencing performance of the silencer is improved.

In the present application, the "sound-deadening tube 20 is designed to be L-shaped" means that the sound-deadening tube is substantially L-shaped, and the whole sound-deadening tube is substantially formed by bending and connecting two tube segments at an angle, which may be, but is not limited to, 75 ° to 125 °, such as 90 ° or 100 °. Of course, the bending portion of the silencing tube may be an arc or an irregular curve with a certain curvature range, or a vertical connection. The connecting part of the two pipe sections can be connected with another straight pipe section to form a three-section type pipeline structure, and the like, and the structure can also be a four-section type pipeline structure, a five-section type pipeline structure and the like. The above examples can realize the non-circuitous circulation of the air flow, can reduce the on-way resistance, and the embodiment is not strictly limited. The "muffler pipe 20 is designed to have an L-shape", and the first pipe segment 21 and the second pipe segment 22 may be integrally formed.

In the first embodiment, the central axis of the first pipe section 21 is substantially perpendicular to the central axis of the second pipe section 22, and the junction between the pipe passage of the first pipe section 21 and the pipe passage of the second pipe section 22 needs to be smoothly transitioned to smooth the airflow.

In the first embodiment, the first partition 30 is fixedly connected to the first pipe section 21, and the first partition 30 and the muffler pipe 20 are formed as an integral module, so that the first partition 30 and the muffler pipe 20 can be assembled into the inner cavity 11 together during assembly, thereby improving assembly efficiency. Further, the first partition plate 30 and the silencer duct 20 are integrally formed, and are injection molded by using a plastic material or a polymer material (such as a PP material or a PC material).

As shown in fig. 2, in the muffler according to the first embodiment, the pipe orifice of the first pipe section 21 is connected to the pipe outlet, specifically, the pipe orifice of the first pipe section 21 is connected to the pipe outlet in a sealing manner, and may be fixed and sealed by a sealant or sealed by a sealing ring. Further, a first slit (not shown, actually, the first slit has the same function as the third through hole 211 of the first pipe section 21 in the second and third embodiments) is formed in the first pipe section 21, and the first slit is communicated with the first cavity 111, that is, the pipe passage of the first pipe section 21 is communicated with the first cavity 111 through the first slit, and the pipe passage of the first pipe section 21 is not communicated with the second cavity 112, so that the flow noise generated by the flow of the gaseous refrigerant in the pipe passage of the first pipe section 21 can be transmitted into the first cavity 111, the transmission space and the reflection distance of the flow noise are enlarged, and the purpose of noise reduction is achieved for the noise generated by the flow of the gaseous refrigerant in the first pipe section 21. Accordingly, the pipe orifice of the second pipe section 22 is connected to the pipe inlet 13, and the second pipe section 22 is provided with a second slit (not shown, in fact, the second slit has a similar function to the first through hole 221 or the second through hole 222 of the second pipe section 22 in the second and third embodiments), and the second slit is communicated with the second chamber 112, and similarly, the flow noise generated by the flow of the gaseous refrigerant in the pipe passage of the second pipe section 22 can be transmitted into the second chamber 112, and the transmission space and the reflection distance of the flow noise are enlarged, so that the purpose of noise reduction of the noise generated by the flow of the gaseous refrigerant in the second pipe section 22 is achieved.

As shown in fig. 1 and 2, the housing 10 includes a main housing 101 and a housing cover 102, the outlet nozzle is formed on the housing cover 102, the inlet nozzle 13 is formed on the main housing 101, and the main housing 101 and the housing cover 102 are connected to form an inner cavity 11. As shown in fig. 3, the inner wall of the main casing 101 is provided with a first fitting groove 117, and the edge of the first partition 30 is inserted into the first fitting groove 117, thereby dividing the inner chamber 11 into the first chamber 111 and the second chamber 112. Thus, the first assembling groove 117 and the first partition plate 30 are matched with each other, so that the first partition plate 30 can be stably assembled in the inner cavity 11, the first partition plate 30 and the L-shaped silencing pipe 20 cannot be randomly deviated, and when the first partition plate 30 and the silencing pipe 20 are assembled, the rapid positioning and the rapid assembling can be achieved, and the assembling efficiency is improved.

Further, after the first partition plate 30 and the sound-deadening tube 20 are assembled into the inner cavity 11, in order to quickly and accurately cover the housing cover 102 on the main housing 101, the edge of the housing cover 102 is provided with the limiting opening 103, and the first partition plate 30 is inserted into the limiting opening 103 toward the edge of the outlet, so as to position and limit the position between the housing cover 102 and the first partition plate 30, so that the assembly relationship among the main housing 101, the housing cover 102, the first partition plate 30 and the sound-deadening tube 20 is more stable.

Example two:

the muffler of the second embodiment has the following differences compared with the muffler of the first embodiment.

During the flowing and conveying process of the gaseous refrigerant flowing from the inlet pipe orifice 13 into the pipe passage of the silencing pipe 20, the gaseous refrigerant is influenced by the on-way resistance along the on-way increasing of the flow of the gaseous refrigerant, so that the flow noise generated by the flow of the gaseous refrigerant in the pipe passage of the second pipe section 22 is smaller than the flow noise generated by the flow of the gaseous refrigerant in the pipe passage of the first pipe section 21. Therefore, in response to the tendency of the flow noise generated by the gaseous refrigerant at different on-way positions of the tube passage of the muffler pipe 20 to be increased, the muffler of the second embodiment of the present invention further includes a second partition plate 40, as shown in fig. 4, and the second partition plate 40 is installed in the second chamber 112 to divide the second chamber 112 into an upper chamber 113 and a lower chamber 114 (see fig. 11 and 19 in combination), the upper chamber 113 being in communication with the first chamber 111. Specifically, the upper chamber 113 and the first chamber 111 can be communicated with each other by forming a hole at a corresponding position of the first partition 30 so that the first chamber 111 is communicated with the upper chamber 113, and the pipe passage of the first pipe section 21 is connected with the first chamber 111 through the first slit, so that the pipe passage of the first pipe section 21 is communicated with both the first chamber 111 and the upper chamber 113, and the pipe orifice of the first pipe section 21 and the pipe outlet are in sealed connection in the second embodiment; as shown in fig. 5 and 6, the first pipe section 21 may be provided with a third through hole 211 and a fourth through hole 212, the third through hole 211 being communicated with the first chamber 111, and the fourth through hole 212 being communicated with the upper chamber 113. In this way, the flow noise generated during the flow of the gaseous refrigerant in the tube passage of the first tube section 21 can be propagated and diffused both to the first cavity 111 and to the upper cavity 113, thereby further reducing the noise. And, the tube passage of the second tube section 22 is communicated with the lower cavity 114, and the tube passage of the second tube section 22 is gas-isolated from the upper cavity 113, the flow noise generated by the flow of the gaseous refrigerant in the tube passage of the second tube section 22 can be propagated into the lower cavity 114, thereby achieving the purpose of noise elimination and noise reduction for the noise generated by the flow of the gaseous refrigerant in the second tube section 22.

Further, the silencer duct 20, the first partition plate 30, and the second partition plate 40 are integrally molded members. Further, the first partition plate 30, the second partition plate 40 and the silencer duct 20 are injection molded by using a plastic material or a polymer material (such as a PP material, a PC material, etc.).

As shown in fig. 7, when the second partition plate 40 is assembled into the inner cavity 11, the inner wall of the main casing 101 is further provided with a supporting step 119, an edge area of a surface of the second partition plate 40 facing away from the nozzle abuts against the supporting step 119, and the second partition plate 40 and the supporting step 119 are arranged in a sealing manner (sealing may be achieved by applying a sealant between the second partition plate 40 and the supporting step 119, or sealing may be achieved by arranging a sealing ring between the second partition plate 40 and the supporting step 119).

As shown in fig. 7, the supporting step 119 is provided with a fastening groove 120, and the edge of the second partition 40 facing the lower chamber 114 is provided with a rib 41, and the rib 41 is inserted into the fastening groove 120. Therefore, the second partition plate 40 can be matched with the supporting step 119 more tightly and stably, the sealing ring is placed in the buckling groove 120, the convex rib 41 is inserted into the buckling groove 120 and then presses the sealing ring, so that the upper cavity 113 and the lower cavity 114 are completely sealed and isolated, and the noise elimination and noise reduction effects of the upper cavity 113 on the gaseous refrigerant flowing in the first pipe section 21 and the noise elimination and noise reduction effects of the lower cavity 114 on the gaseous refrigerant flowing in the second pipe section 22 are independent from each other.

Compared with the muffler of the first embodiment, the muffler of the second embodiment has the same structure except for the above structure, and thus, the description thereof is omitted.

Example three:

compared with the muffler of the second embodiment, the muffler of the third embodiment has the following differences:

as shown in fig. 8 to 14, the muffler further includes a third partition plate 50, the third partition plate 50 is installed in the lower chamber 114 to divide the lower chamber 114 into a first lower chamber 115 and a second lower chamber 116, the pipe wall of the second pipe segment 22 is provided with a first through hole 221 and a second through hole 222, the first through hole 221 is communicated with the first lower chamber 115, and the second through hole 222 is communicated with the second lower chamber 116. In this way, flow noise generated by the flow of the gaseous refrigerant in the tube passage of the second tube section 22 can be propagated into the first lower chamber 115 and the second lower chamber 116, respectively, thereby achieving the purpose of noise reduction for the noise generated by the flow of the gaseous refrigerant in the second tube section 22.

As shown in fig. 10 and 11, the nozzle of the first pipe section 21 is connected to the outlet nozzle, and the nozzle of the first pipe section 21 is sealed with the outlet nozzle, specifically, the nozzle may be fixed and sealed by a sealant, or sealed by a sealing ring. As shown in fig. 12 to 14, the first pipe section 21 is provided with a third through hole 211 and a fourth through hole 212, the third through hole 211 communicates with the first chamber 111, and the fourth through hole 212 communicates with the upper chamber 113.

In the third embodiment, the silencer duct 20, the first partition plate 30, the second partition plate 40, and the third partition plate 50 are integrally formed members. Further, the silencing tube 20, the first partition plate 30, the second partition plate 40 and the third partition plate 50 are injection molded by using a plastic material or a polymer material (such as a PP material, a PC material, etc.).

As shown in fig. 15, the inner wall of the main casing 101 is further provided with a second assembling groove 118, and the edge of the third partition 50 is inserted into the second assembling groove 118, so that the third partition 50 can be assembled quickly during the assembling process, and the third partition 50 is positioned and limited by the second assembling groove 118, so that the third partition 50 does not move in position in the inner cavity 11.

Compared with the muffler of the second embodiment, the muffler of the third embodiment has the same structure except for the above structure, and thus the description thereof is omitted.

Example four:

the muffler of example four has the following differences compared with the muffler of example three.

As shown in fig. 16 to 21, the nozzle of the first pipe section 21 is opposite to the outlet nozzle, and the nozzle of the first pipe section 21 faces the outlet nozzle without contacting, that is, there is a gap between the nozzle of the first pipe section 21 and the outlet nozzle, and the gap between the nozzle of the first pipe section 21 and the outlet nozzle is small, and the gap is communicated with the first cavity 111 and the upper cavity 113. Thus, during operation, the compressor generates negative pressure to suck air, so that the gaseous refrigerant flowing in the muffler pipe 20 directly enters the outlet pipe from the pipe orifice of the first pipe section 21 and does not flow into the first cavity 111 and the upper cavity 113 from the gap between the pipe orifice and the outlet pipe orifice of the first pipe section 21, but the flow noise generated by the flow of the gaseous refrigerant in the first pipe section 21 is transmitted into the first cavity 111 and the upper cavity 113 through the gap, so that the noise generated by the flow of the gaseous refrigerant in the first pipe section 21 is muffled and reduced.

Compared with the silencer of the third embodiment, the silencer of the fourth embodiment has the same structure except for the above structure, and thus the description thereof is omitted.
