DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Moreover, repeated reference numerals or designations may be used in various embodiments. These iterations are merely for simplicity and clarity of describing the present invention, and are not intended to represent any correlation between the different embodiments or configurations discussed.
As shown in fig. 1 to 3, the present invention provides a pipe silencer 100, wherein the pipe silencer 100 includes a main body 1, and an inlet pipe 2 and an outlet pipe 3 disposed at two sides of the main body 1, which are far away from each other, and the inlet pipe 2 and the outlet pipe 3 are far away from each other and extend in opposite directions to function as a connection in a pipe. In the present embodiment, the pipe muffler 100 is applied to a refrigeration system of a refrigerator, and thus refrigerant flows in the pipe muffler 100. Also, since the refrigerant performs a heat exchange function, the refrigerant generally has two states, a liquid state and a gaseous state. Of course, the pipeline muffler 100 may also be applied to other scenes, as long as it can perform the function of muffling, and the purpose of the present invention can be achieved. Also, the pipe muffler 100 includes an inlet 101 and an outlet 102 to communicate with other structures, and the inlet 101 is provided on the inlet pipe 2 and the outlet 102 is provided on the outlet pipe 3.
Specifically, in the present invention, the inlet pipe 2 includes a first flow-splitting section 21, a second flow-splitting section 22 and a first communicating section 23, one end of each of the first flow-splitting section 21 and the second flow-splitting section 22 is communicated with the main body 1, the other end is communicated with the first communicating section 23, and the inlet 101 is disposed on the first communicating section 23; the first flow-dividing section 21 is disposed above the second flow-dividing section 22.
The first communicating section 23 is provided with the inlet 101, so that the first communicating section 23 communicates with the upper structure. While the fluid passing through the first communicating section 23 may continue through the first flow-splitting section 21 and the second flow-splitting section 22 and form a flow split over the first flow-splitting section 21 and the second flow-splitting section 22. Further, since the first flow-dividing section 21 is provided above the second flow-dividing section 22, if the fluid is a gas-liquid coexisting fluid, most of the liquid sinks into the second flow-dividing section 22 located below due to the gravity, and most of the gas floats into the first flow-dividing section 21 located above, thereby achieving gas-liquid separation. And the first flow-dividing section 21 and the second flow-dividing section 22 are respectively communicated to the main body part 1, so that the gas and the liquid are also separated from each other in the main body part 1, and the noise generated by the mixing of the gas and the liquid is avoided.
In addition, particularly, if the pipeline muffler 100 is connected to a refrigeration system of a refrigerator, since the refrigerant can be converted between a gas state and a liquid state to change the phase, the pipeline muffler 100 of the present invention can sufficiently separate gas and liquid, thereby further preventing noise generated in the pipeline due to the gas-liquid phase change of the refrigerant. Therefore, the phase change noise generated by gas-liquid mixing phase change is avoided, and the silencing effect is achieved.
In the present embodiment, the cross-sectional area of the main body portion 1 in the flow direction is larger than the sum of the first flow-dividing section 21 and the second flow-dividing section 22. As shown in fig. 1 to 2, the first flow-dividing section 21 and the second flow-dividing section 22 are both small in pipe diameter, and the cross-sectional area in the flow direction of the main body 1 is much larger than the sum of the first flow-dividing section 21 and the second flow-dividing section 22. Therefore, after the fluid passes through the body 1, the volume and the flow rate of the fluid are increased by the body 1, so that the flow velocity of the fluid is decreased, and the fluid can be buffered.
Further, as described above, since the first flow dividing section 21 is located above the second flow dividing section 22, it is apparent that the connection position of the first flow dividing section 21 and the main body 1 is also located above the connection position of the second flow dividing section 22 and the main body 1, and thus when the fluid flows in the main body 1, the gas is located above and the liquid is located below, and the two states of the fluid do not interfere with each other, thereby further reducing noise. In addition, if the main body 1 is applied to a refrigeration system of a refrigerator, the main body can further promote the cooling of the refrigerant in a gas state to be in a liquid state, so that the lower-level structure can conveniently work.
Since the properties of the fluid passing through the pipe muffler 100, such as density and viscosity, are determined, the noise sound wave generated by the phase change of the fluid mixture passing through the pipe muffler 100 is also determined, and the noise sound wave is the target noise reduction sound wave of the pipe muffler 100. Assuming that the wavelength of the target noise reduction sound wave is λ, the length L of the main body portion 1 in the extending direction is (2n +1) λ/4, (n is 0,1,2,3, …) for noise reduction, that is, n is a natural number. Thus, the noise sound wave can be effectively attenuated.
Further, the main body 1 extends in a horizontal direction and includes a lower side surface 11 located at a lower side of the main body 1, and in the present embodiment, the main body 1 is in a shape of a circular tube, so that the lower side surface 11 is a semicircular area at the lower side of the main body 1. The outlet tube 3 extends downwardly from the lower side 11 and is located entirely below the main body 1. According to the above, since the liquid is deposited on the lower side of the main body part 1, the gas floats up on the upper side of the liquid, and the joint of the outlet pipe 3 and the main body part 1 is located on the lower side 11 of the main body part 1, the outlet pipe 3 can make most of the liquid flow out, so that the noise sound wave caused by gas-liquid mixing caused by the simultaneous outflow of the liquid and the gas is further avoided.
In order to control the flow rate of the fluid in the main body 1, the main body 1 is arranged to extend in a horizontal direction so as to make the flow rate of the fluid more stable without increasing faster. Of course, if the main body 1 is slightly inclined to control the fluid flow rate faster or slower, the object of the present invention can be achieved.
In addition, regarding the arrangement of the outlet pipe 3, as shown in fig. 1, which is the first embodiment of the present invention, the outlet pipe 3 is provided in one piece and has a cross-sectional area in the flow direction larger than the first and second flow-dividing sections 21 and 22, so that the flow rate of the fluid flowing out can be ensured. In particular, in the refrigerator, since there is a possibility that the refrigerating capacity of the refrigerator is insufficient due to insufficient refrigerant, the flow rate of the outlet pipe 3 must be secured. The outlet pipe 3 comprises a bent section 31 and a horizontal section 32, the bent section 31 extends from the lower side 11 of the main body 1 in a bent manner, and the horizontal section 32 is parallel to the extending direction of the main body 1.
Alternatively, as shown in fig. 2, the second embodiment of the present invention is described. In the second embodiment, the arrangement of the water outlet pipe 3 is similar to that of the water inlet pipe 2, specifically, the water outlet pipe 3 includes a third diversion section 31, a fourth diversion section 32 and a second communication section 33, one end of each of the third diversion section 31 and the fourth diversion section 32 is communicated with the main body portion 1, the other end of each of the third diversion section 31 and the fourth diversion section 32 is communicated with the second communication section 33, and the outlet 102 is arranged on the second communication section 33. That is, in the present embodiment, the water outlet pipe 3 is also provided with a shunt to divide the fluid into two paths to pass through the water outlet pipe 3, so that the flow velocity of the fluid can be further slowed down, and the noise reduction effect is further improved.
Further, as described above, since the outlet pipe 3 extends from the lower surface of the main body 1, the connection positions of the third flow dividing section 31 and the fourth flow dividing section 32 with the main body 1 are also located on the lower surface of the main body 1 and are distributed in the extending direction of the main body 1. Furthermore, the third flow-splitting section 31 and the fourth flow-splitting section 32 have a length difference L2 ═ λ (2n +1)/2, where n is 0,1,2,3 … …. Therefore, even if noise is generated after the fluid passes through the third branch flow section 31 and the fourth branch flow section 32, the noise sound wave generated by the fluid finally entering the second communicating section 33 can be cancelled. In the present embodiment, for better arrangement of the third flow-splitting section 31 and the fourth flow-splitting section 32, the third flow-splitting section 31 is located above the fourth flow-splitting section 32, and the length of the fourth flow-splitting section 32 is longer. The second communicating portion 33 is still parallel to the extending direction of the main body portion 1.
Therefore, the present invention also provides a refrigerator applying the above pipeline muffler 100. Specifically, the refrigeration system of the refrigerator includes a compressor 10, a condenser 20, a capillary tube 30, a heat regenerator 40 and an evaporator which are communicated with each other, and the pipeline muffler 100 is disposed between the capillary tube 30 and the evaporator. Refrigerant in the refrigerating system is high temperature gaseous state at first, then becomes high temperature liquid through compressor 10, dispels the heat through condenser 20 and becomes microthermal gaseous state again, carries out further cooling through regenerator 40 and capillary 30 and forms microthermal gas-liquid mixture, at last absorbs the heat through the evaporimeter and cools down to the refrigerator, and the refrigerant then becomes high temperature gaseous state. Therefore, the refrigerant passing through the capillary tube 30 is in a gas-liquid mixed state, and the refrigerant in a gas state is further in a gas-liquid mixed phase, which causes a large noise, and therefore, the noise of the refrigerator can be further reduced by disposing the pipe muffler 100 between the capillary tube 30 and the evaporator in the present invention. Of course, the inlet 101 of the line muffler 100 communicates with the capillary tube 30, and the outlet 102 communicates with the evaporator.
Specifically, in order to improve the fresh-keeping and freezing effects in the conventional refrigerator, the evaporator includes a refrigerating evaporator 51 and a freezing evaporator 52, and the two pipe mufflers 100 are respectively connected between the capillary tube 30 and the refrigerating evaporator 51 and between the capillary tube 30 and the freezing evaporator 52. Of course, if there are multiple evaporators, multiple line mufflers 100 may be provided to cooperate with the evaporators.
Therefore, in summary, the present invention provides a pipeline muffler 100 and a refrigerator comprising the same, in the present invention, an inlet pipe 2 of the pipeline muffler 100 has a first branch section 21 located above and a second branch section 22 located below, so that a fluid entering the inlet pipe 2 can be automatically divided into a gas and a liquid, and correspondingly delivered into a main body portion 1, and noise caused by phase change of mixture of the gas and the liquid is avoided. And, further, the outlet pipe 3 provides two embodiments, and also the generation of noise can be further prevented. Therefore, the pipe muffler 100 is disposed between the capillary tube 30 and the evaporator of the refrigeration system of the refrigerator, so that the refrigerant in a gas-liquid mixture state passes through the pipe muffler 100 and mostly flows out as a liquid refrigerant, thereby preventing the refrigerant in the gas-liquid mixture from being mixed and changed in phase to generate noise when flowing further. Therefore, the noise reduction effect is better without additionally arranging external wrapping daub and the like, the cost is reduced, and the noise reduction effect is also better.
