[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Refrigeration equipment is equipment that controls and regulates temperature, such as refrigerators, freezers, etc. Refrigerators preserve, refrigerate, and freeze food and beverages by lowering the temperature to extend their shelf life and maintain their quality. They are widely used. In related technologies, the refrigeration system of a refrigerator is its core component, which is mainly composed of four basic parts: a compressor, a condenser, a throttling assembly, and an evaporator. They are connected by pipes to form a closed circulation system, using refrigerant as the working medium, and the purpose of heat transfer and lowering the temperature is achieved through the circulation of the refrigerant. An exhaust evaporator is provided in the refrigerator, and the exhaust evaporator is connected to the high-pressure exhaust side of the compressor. Since the refrigerant discharged by the compressor is a high-temperature gas, the exhaust evaporator is in a high-temperature state, and the exhaust evaporator contacts the defrost water in the water tray to help evaporate and eliminate the defrost water.

[0037] At present, the exhaust evaporator pipe is directly connected to the compressor, and the vibration of the compressor will be transmitted to the exhaust evaporator pipe. The exhaust evaporator pipe vibrates greatly. In order to reduce the shaking vibration, shock-absorbing rubber blocks will be installed on the exhaust evaporator pipe. However, the shock-absorbing effect of the shock-absorbing rubber blocks is not ideal, and the shock-absorbing rubber blocks are not installed firmly. In addition, the vibration of the pipe may bring more noise, which needs to be improved.

[0038] To this end, an embodiment of the first aspect of the utility model proposes an exhaust evaporator pipe assembly, in which a muffler is arranged on the exhaust evaporator pipe, and the weight of the muffler itself is used to effectively reduce the vibration and noise of the exhaust evaporator pipe.

[0039] Reference Figures 1 to 3The embodiment of the first scheme of the utility model proposes an exhaust evaporator pipe assembly, including an exhaust evaporator pipe 100 and a muffler 110. The muffler 110 is connected to the exhaust evaporator pipe 100. The weight of the muffler 110 itself can provide damping effect to the exhaust evaporator pipe 100, effectively reducing the vibration of the exhaust evaporator pipe 100. The exhaust evaporation pipe 100 is divided into a plurality of pipe sections, and there is at least one muffler 110, and a connecting port 112 is provided at both ends of the muffler 110, and a muffler cavity 111 is provided at the connecting ports 112 at both ends of the muffler 110, and the connecting port 112 is connected to the muffler cavity 111, and a pipe section of the exhaust evaporation pipe 100 is respectively provided at each of the connecting ports 112 at both ends of the muffler 110, so that the plurality of pipe sections and at least one muffler 110 are connected in series as one, and the high-temperature gas in the exhaust evaporation pipe 100 enters the muffler cavity 111 from the connecting port 112 at one end, and flows out of the muffler cavity 111 from the connecting port 112 at the other end, and the muffler cavity 111 absorbs and weakens the sound wave energy of the high-temperature gas, effectively reducing noise. Among them, the pipe section of the exhaust evaporation pipe 100 can be inserted into the connecting port 112, or the connecting port 112 can be a pipe opening and the pipe section can be inserted.

[0040] Reference Figure 2 In some embodiments of the first aspect of the utility model, the exhaust evaporation pipe assembly includes a plurality of silencers 110, and the plurality of silencers 110 greatly increase the weight of the exhaust evaporation pipe 100 and reduce the vibration of the exhaust evaporation pipe 100. The high-temperature gas in the exhaust evaporation pipe 100 gradually absorbs and weakens the sound wave energy through the plurality of silencers 110, which can effectively reduce the noise. The plurality of silencers 110 can be silencers 110 of different specifications. By combining and using silencers 110 of different specifications, the sound silencing band of the plurality of silencers 110 is increased to improve the silencing effect. It can be understood that the silencers 110 of different specifications include but are not limited to: different sizes such as diameter, length, inlet and outlet sizes, different materials such as stainless steel, aluminum alloy, different shapes such as round tubes, rectangular tubes, different types such as impedance silencers, resistance silencers, and the like.

[0041] Reference Figure 2In some embodiments of the first aspect of the present utility model, it can be understood that the exhaust evaporation pipe 100 is connected to a plurality of silencers 110, the plurality of silencers 110 and the plurality of pipe sections are connected in series, the volumes of the silencer chambers 111 of the plurality of silencers 110 are different, and the silencer chambers 111 of different volumes absorb and weaken noises of different frequencies. The larger the volume of the silencer chamber 111 of the silencer 110, the more space the silencer chamber 111 can have to reflect and absorb sound waves, thereby reducing the transmission of sound waves. Since low-frequency noise usually has a longer Wavelength, need a larger space to accommodate and interact with it, so the silencer 110 with a larger volume of the silencer cavity 111 is better at absorbing low-frequency noise; the smaller the volume of the silencer cavity 111 of the silencer 110, because high-frequency noise has a shorter wavelength, it is easier to be absorbed and attenuated in a smaller space, so the silencer 110 with a smaller volume of the silencer cavity is better at absorbing higher-frequency noise, and through multiple silencer cavities 111 with different volumes, it is possible to absorb noise of different frequencies, improve the silencing effect, and effectively reduce noise. It is understandable that the volumes of the silencer cavities 111 of multiple silencers 110 are different, and they can be silencer cavities 111 of different lengths, silencer cavities 111 of different cross-sectional areas, etc., and silencers 110 of different specifications are selected according to actual application conditions.

[0042] It is understandable that, referring to Figure 5 In some embodiments of the first aspect of the present utility model, the muffler 110 includes a round tube 113, a first connecting tube 114 and a second connecting tube 115, the communication port 112 is located at the ends of the first connecting tube 114 and the second connecting tube 115, conical sleeves 116 are provided at both ends of the round tube 113, and a muffler chamber 111 is formed inside the round tube 113. The first connecting tube 114 and the second connecting tube 115 are connected to the conical sleeve 116, and the first connecting tube 114 and the second connecting tube 115 are respectively connected to the exhaust evaporation pipe 100, and the high-temperature gas of the exhaust evaporation pipe 100 enters from the first connecting tube 114 through the conical sleeve 116. The high-temperature gas enters the silencer chamber 111, and the conical sleeve 116 gradually expands the area of ​​the air flow channel for the high-temperature gas to enter the silencer 110, thereby reducing the violent disturbance and reflection of the high-temperature gas at the first connecting pipe 114 and the circular pipe 113 due to the sudden change in cross section, helping to guide the high-temperature gas into the silencer chamber 111, reducing the formation of eddies and turbulence, and reducing noise. The high-temperature gas flows out of the silencer 110 from the conical sleeve 116 through the second connecting pipe 115 in the silencer chamber 111, guiding the high-temperature gas to flow out of the silencer 110, increasing the flow rate of the high-temperature gas flowing out of the silencer 110, reducing the transmission range of the noise, and improving the silencer effect.

[0043] It is understandable that, referring to Figure 3 and Figure 7In some embodiments of the first aspect of the present invention, the muffler 110 includes a round tube 113, a first connecting tube 114, and a second connecting tube 115. The round tube 113 is provided with connecting portions 118 at both ends. The first connecting tube 114 and the second connecting tube 115 are connected to the connecting portions 118. One end of the first connecting tube 114 and the second connecting tube 115 is arranged in the muffler cavity 111. The other ends of the first connecting tube 114 and the second connecting tube 115 form a connecting port 112. The interior of the round tube 113 forms the muffler cavity 111. The high-temperature gas of the exhaust evaporation pipe 100 is discharged from the first connecting tube 114 to the muffler cavity 111. The high-temperature gas enters the silencer chamber 111 in the circular tube 113 and flows out of the silencer 110 from the second connecting pipe 115. Since one end of the first connecting pipe 114 and the second connecting pipe 115 are arranged in the silencer chamber 111, the high-temperature gas needs to pass through a more complicated path inside the silencer chamber 111 before being discharged from the second connecting pipe 115, which increases the contact time and area of ​​the high-temperature gas in the internal structure of the silencer 110 to enhance the absorption and attenuation of the high-temperature gas sound waves, and helps the high-temperature gas to form a uniformly distributed airflow in the silencer chamber 111, reduce the noise generated by unstable airflow, and improve the silencing effect.

[0044] It can be understood that in some embodiments of the first aspect of the present invention described above, reference is made to Figure 3 and Figure 7 The muffler includes a round tube 113, a first connecting tube 114 and a second connecting tube 115, one end of the first connecting tube 114 and the second connecting tube 115 are arranged in the muffler chamber 111, and two ends of the round tube 113 are provided with connecting parts 118 for connecting the first connecting tube 114 and the second connecting tube 115. In the production process of the muffler 110, the round tube 113, the first connecting tube 114, the second connecting tube 115 and the connecting part 118 need to be produced separately, and then the round tube 113, the first connecting tube 114, the second connecting tube 115 and the connecting part 118 are connected as a whole by welding or the like; it can be understood that, referring to Figure 5The silencer 110 includes a round tube 113, a first connecting tube 114 and a second connecting tube 115. Conical sleeves 116 are provided at both ends of the round tube 113. During the production process of the silencer 110, the conical sleeves 116 are formed by a shrinking process. The conical sleeves 116 can be formed by a shrinking process at both ends of the round tube 113 so that the round tube 113 and the conical sleeves 116 at both ends are integrated, and then the conical sleeves 116 and the first connecting tube 114 and the second connecting tube 115 are fixedly connected by welding or the like. Alternatively, the first connecting tube 114 can be formed by a shrinking process. One end is formed into a conical sleeve 116 by a flaring process, so that the first connecting pipe 114 and the conical sleeve 116 are integrated. At the same time, one end of the second connecting pipe 115 is produced into a conical sleeve 116 by a flaring process, so that the second connecting pipe 115 and the conical sleeve 116 are integrated. Then, the two ends of the round tube 113 are respectively connected to the conical sleeve 116 by welding or the like. Alternatively, the two ends of the round tube 113 are respectively formed into a conical sleeve 116 and the first connecting pipe 114, the conical sleeve 116 and the second connecting pipe 115 by a shrinking process to form an integrated structure. The shrinking process or the flaring process is used to first produce several components of the muffler 110 as one, and then the overall assembly and welding are performed, which reduces the processing difficulty, is conducive to the production of the muffler 110, and can reduce the welding area of ​​the structure of the muffler 110, thereby improving the structural strength of the muffler 110, which is conducive to improving the sealing of the muffler 110.

[0045] It can be understood that in some embodiments of the first aspect of the utility model mentioned above, the specific production steps of the muffler 110 can be considered according to the different specifications of the muffler 110, production costs and other aspects, and the present application does not make the sole limitation.

[0046] Reference Figure 6It can be understood that in some embodiments of the first aspect of the present utility model, the muffler includes a round tube 113, a first connecting tube 114, a second connecting tube 115, a tapered sleeve 116 and a connecting portion 118, the tapered sleeve 116 is used to connect the first connecting tube 114 and the round tube 113, the inner diameter of the tapered sleeve 116 gradually increases from one end connected to the first connecting tube 114 to one end of the round tube 113, the connecting portion 118 is used to connect the second connecting tube 115 and the round tube 113, and the shape of the connecting portion 118 is similar to that of the round tube 113. The cross-sectional shape of the round tube 113 corresponds to that of the round tube 113, and the muffler chamber 111 is formed in the round tube 113. The communication port 112 is located in the first connecting tube 114 and the second connecting tube 115. A sound absorbing component 117 made of a sound absorbing material is arranged in the muffler chamber 111. The first connecting tube 114 and the second connecting tube 115 are connected to the exhaust evaporation pipe 100 at both ends. The sound absorbing component 117 is located in the muffler chamber 111 and one end of the second connecting tube 115 is provided. The high-temperature gas in the exhaust evaporation pipe 100 enters from the first connecting tube 114 through the conical sleeve 116. The conical sleeve 116 can make the high-temperature gas enter the silencer chamber 111 in a process of gradually expanding the cross-sectional area, so as to reduce the unstable flow of the high-temperature gas caused by the sudden change of the cross section when the first connecting pipe 114 enters the silencer chamber 111, which is conducive to guiding the high-temperature gas into the silencer chamber 111, and is conducive to the smooth flow of the high-temperature gas in the silencer chamber 111, further reducing the noise and improving the silencer effect. A sound absorbing component 117 is provided at one end of the silencer chamber 111 close to the second connecting pipe 115. The sound-absorbing material of the component 117 can absorb and reduce the sound wave energy of the high-temperature gas, reduce the transmission and diffusion of the sound, and the high-temperature gas in the silencing chamber 111 further absorbs and weakens the sound wave energy through the sound-absorbing component 117, and then flows out of the muffler 110 from the second connecting pipe 115. The conical sleeve 116 and the silencing chamber 111 are connected through the first connecting pipe 114. The sound-absorbing component 117 is arranged at one end of the second connecting pipe 115, which can enable the muffler 110 to absorb and weaken noise in a wider frequency range, thereby effectively reducing noise.

[0047] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 5Conical sleeves 116 are provided at both ends of the muffler 110, the first connecting pipe 114 and the second connecting pipe 115 are connected to the conical sleeves 116, a muffler chamber 111 is formed inside the circular tube 113, the communication port 112 is located in the first connecting pipe 114 and the second connecting pipe 115, the first connecting pipe 114 and the second connecting pipe 115 are connected to the exhaust evaporation pipe 100, a sound absorbing component 117 made of a sound absorbing material is arranged in the muffler chamber 111, the sound absorbing component 117 is located in the muffler chamber 111 near one end of the second connecting pipe 115, the shape of the sound absorbing component 117 corresponds to the shape of the conical sleeve 116, and the high-temperature gas in the exhaust evaporation pipe 100 enters the muffler chamber 111 from the first connecting pipe 114 through the conical sleeve 116, The setting of the conical sleeve 116 plays a role in guiding and slowing down the sudden change of the cross-section of the first connecting pipe 114 and the silencer chamber 111, so that when the high-temperature gas enters the silencer chamber 111 and flows out of the silencer chamber 111, the noise can be further reduced and the silencer effect can be improved. At the same time, a sound absorbing component 117 is arranged at one end of the second connecting pipe 115 provided in the silencer chamber 111. The high-temperature gas first passes through the sound absorbing component 117 in the silencer chamber 111 and then enters the second connecting pipe 115. The sound absorbing material of the sound absorbing component 117 can absorb and weaken the energy of sound waves. The shape of the sound absorbing component 117 corresponds to the shape of the conical sleeve 116, so that the high-temperature gas in the muffler 110 can fully contact the sound absorbing component 117, thereby further enhancing the silencer effect.

Since one end of the first connecting pipe 114 and the second connecting pipe 115 are located in the silencer chamber 111, the contact time and area of ​​the high-temperature gas with the internal structure of the silencer 110 are increased, which is beneficial to the absorption and attenuation of the sound wave energy of the high-temperature gas. Combined with the arrangement of the sound-absorbing component 117 in the silencer chamber 111, it is beneficial to increase the contact time and area between the high-temperature gas and the sound-absorbing component 117, further absorb and attenuate the sound wave energy of the high-temperature gas, improve the noise reduction effect, and thus effectively reduce the noise.
