The valve body 20 includes a valve seat 21, a valve core 22, and a filter net 23, and the valve body 20 is installed in at least one of the two installation cavities 111.

As shown in fig. 1 and 3, an inlet pipe section 11 and an outlet pipe section 12 are connected to both ends of a muffler pipe section 13, respectively, and are integrally formed with the muffler pipe section 13 by an integral molding technique. The diameters of the inlet pipe section 11 and the outlet pipe section 12 are smaller than that of the sound attenuation pipe section 13, the valve body 20 can be installed in the installation cavity 111 of the inlet pipe section 11 and/or the outlet pipe section 12, the valve seat 21 and the valve core 22 of the valve body 20 are sequentially and axially connected in the installation cavity 111, the installation cavity 111 is communicated with the sound attenuation cavity 131, and the valve core 22 is closer to the sound attenuation pipe section 13 than the valve seat 21. A filter screen 23 is further arranged on one side, away from the valve core 22, of the valve seat 21, and the filter screen 23 is sleeved on the valve seat 21.

Therefore, the inlet pipe section 11, the silencing pipe section 13 and the outlet pipe section 12 are integrally connected along the axial direction, the welding of the inlet pipe section 11, the outlet pipe section 12 and the silencing pipe section 13 is avoided, the structural strength of the air-conditioning silencer assembly 100 is increased, the possibility of refrigerant leakage is reduced, and meanwhile, the assembly cost is reduced. The valve body 20 is integrated in the mounting cavity 111, so that the structure of the air-conditioning silencer assembly 100 is optimized, and the air-conditioning silencer assembly 100 has the functions of silencing and throttling.

As shown in fig. 3 and 4, the fixing ring 30 is disposed near the silencing pipe section 13 in the installation cavity 111, refrigerant can flow through the fixing ring 30, the valve core 22 is located between the fixing ring 30 and the valve seat 21 and can move axially along the installation cavity 111, and the filter screen 23 is installed at one end of the valve seat 21 away from the valve core 22. The valve seat 21 is fixed in the installation cavity 111, and the valve seat 21 is further provided with grooves 212 distributed in the circumferential direction, so that the filter screen 23 is convenient to fix and install and is prevented from falling off, and the filtering effect is influenced.

Therefore, the fixing ring 30 is arranged at a position close to the silencing pipe section 13, so that the limit of the valve body 20 is increased, the axial displacement of the valve core 22 in the mounting cavity 111 is controlled, and the working efficiency of the valve body 20 is improved. The valve core 22, the valve seat 21 and the filter screen 23 are axially distributed in sequence, so that the refrigerant flows more smoothly, the resistance in the flowing process is reduced, impurities can be filtered preferentially, and the influence on the work of the valve body 20 is reduced.

The cross-sectional area of the conical section of the filter screen 23 gradually decreases in the direction away from the valve element 22, and the conical section contacts the positioning flange a to limit the position of the filter screen 23 axially moving in the mounting cavity 111, so that the contact area between the filter screen 23 and the refrigerant increases.

In addition, a limit boss b is further arranged inside the mounting cavity 111, and the limit boss b is located between the two positioning flanges a, so that the movement of the valve seat 21 in the radial direction of the mounting cavity 111 is limited, the displacement of the valve seat 21 in the axial direction is limited, the position of the valve seat 21 in the mounting cavity 111 is controlled, and the stroke of the valve core 22 is shortened.

Therefore, the positioning flange a is arranged on the inner wall of the mounting cavity 111, so that the positions of the fixing ring 30 and the filter screen 23 can be limited, and the filter screen can be mounted in the mounting cavity 111 more tightly. One section of the filter screen 23 is arranged to be a tapered section 231, so that the filter screen 23 can be conveniently installed, meanwhile, flowing refrigerant can circumferentially flow into the valve seat 21, the filtering area is increased, and the filtering is more sufficient.

As shown in fig. 2, one end of the valve seat 21 abuts against the filter mesh 23 and the other end has a conical flaring 211, and one end of the valve core 22 facing the valve seat 21 has a conical outer wall 221 matching with the conical flaring 211.

That is, the valve seat 21 is installed between the strainer 23 and the valve body 22, and the strainer 23 is installed at one end of the valve seat 21 and the tapered flare 211 is formed at the other end. The conical flare 211 gradually shrinks from the spool 22 to the strainer 23 along the axial direction of the mounting cavity 111, and the spool 22 is closer to the muffler pipe section 13 than the strainer 23. The conical flaring 211 is engaged with a conical outer wall 221 of the valve core 22 at an end close to the fixing ring 30, and the conical outer wall 221 of the valve core 22 is a step surface with a certain chamfer.

Therefore, the conical outer wall 221 of the valve core 22 is convenient to match with the conical flaring 211, the adaptability of the valve core 22 and the valve seat 21 is improved, and the movable valve core 22 can be quickly and accurately connected to the valve seat 21 in the moving process.

In one embodiment, valve bodies 20 are disposed in the mounting cavity 111 of the inlet pipe section 11 and the mounting cavity 111 of the outlet pipe section 12, and the two valve bodies 20 are symmetrically distributed relative to the sound attenuation pipe section 13. As shown in fig. 1, the inlet pipe section 11 and the outlet pipe section 12 are long enough to be connected to both ends of the muffler pipe section 13, respectively, and the valve bodies 20 are installed in the installation cavities 111, respectively, so that the air conditioner muffler assembly 100 is completely symmetrical, and the lengths of the inlet pipe section 11 and the outlet pipe section 12 can be designed according to the use environment.

Therefore, the inlet pipe section 11 and the outlet pipe section 12 which are symmetrically distributed do not need to consider the positive and negative directions, the convenience of the air conditioner silencer assembly 100 during installation is improved, two times of filtering and throttling are achieved, the filtering times are increased, the filtering is more thorough, and the flowing of the refrigerant in the air conditioner silencer assembly 100 is further controlled.

In another embodiment, the valve body 20 is disposed in the mounting cavity 111 of the outlet pipe section 12, and the filter screen 23 is disposed in the mounting cavity 111 of the inlet pipe section 11. As shown in fig. 3, the valve body 20 is disposed at one end of the sound attenuation pipe section 13, which may be the inlet pipe section 11 or the outlet pipe section 12, and if the valve body 20 is disposed in the mounting cavity 111 of the outlet pipe section 12, the other end of the sound attenuation pipe section 13 is the inlet pipe section 11, and the filter screen 23 is disposed in the inlet pipe section 11. The refrigerant does not have throttling function when flowing into the inlet pipe section 11 of the air-conditioning silencer assembly 100, can be simply filtered and then flows through the silencing pipe section 13, and because the diameter of the silencing pipe section 13 is larger than that of the inlet pipe section 11, the flow speed of the refrigerant can be reduced, the refrigerant can flow more stably, finally flows into the channel of the valve body 20 and flows out of the air-conditioning silencer assembly 100 after being throttled and filtered. The lengths of the inlet pipe section 11 and the outlet pipe section 12 can be adjusted according to installation conditions. On the contrary, the valve body 20 is installed in the inlet pipe section 11, and the filter screen 23 is installed in the corresponding outlet pipe section 12, which is not described in detail.

Thus, by installing the valve body 20 in the inlet pipe section 11 or the outlet pipe section 12, the axial length of the air conditioner muffler assembly 100 can be adjusted to accommodate more installation environments, and the structure is more compact.

Specifically, the sound attenuation pipe section 13 includes a cylindrical pipe section 132 and tapered pipe sections 133 connected to both ends of the cylindrical pipe section 132, wherein one tapered pipe section 133 is connected between the inlet pipe section 11 and the cylindrical pipe section 132, and the other tapered pipe section 133 is connected between the outlet pipe section 12 and the cylindrical pipe section 132.

Therefore, the connecting part of the silencing pipe section 13, the inlet pipe section 11 and the outlet pipe section 12 is set to be conical, so that the refrigerant flowing into the silencing pipe section 13 from the inlet pipe section 11 can flow in along the conical pipe section 133, the phenomenon that the height difference between the inlet pipe section 11 and the silencing pipe section 13 is too large to generate larger noise is avoided, the conical pipe section 133 can further reduce the noise of the flowing refrigerant, and the silencing effect of the air conditioner silencer assembly 100 is more remarkable.

Alternatively, as shown in FIG. 5, the inner diameters of inlet tube segment 11 and outlet tube segment 12 are the same, and the inner diameter D2 of cylindrical tube segment 132 is 1.5-3 times the inner diameter D1 of outlet tube segment 12. The axial length of the sound attenuation pipe section 13 is L, the length of the inlet pipe section 11 or the outlet pipe section 12 provided with the valve body 20 is L1, L is 1.5-3 times of L1, and the axial length of the cylindrical pipe section 132 is L2.

According to the formula:

m＝(D₂/D₁)²、k＝2πf/c、

may be used to calculate the expansion ratio, frequency, etc. For example, the required sound deadening amount can be determined according to the practical environment of the product, the required expansion ratio can be inversely deduced, the sectional area of the other pipe section matched with the sound deadening pipe section 13 or the outlet pipe section 12 is conveniently manufactured under the condition that the sectional area of the other pipe section is determined, and finally the outlet pipe section 12, the inlet pipe section 11 and the sound deadening pipe section 13 are integrated into a whole according to the designed value.

In the formula: m is the expansion ratio, L2 is the length (unit: m) of cylindrical pipe section 132, k is the wave number, f is the effective muffling frequency of muffling pipe section 13, c is the sound velocity (unit: m/s), D₁Is the diameter (unit: m) of the inlet pipe section 11, D₂Is the diameter (unit: m) of the cylindrical tube segment 132.

Therefore, by controlling the ratio of the diameters of the cylindrical pipe section 132 and the outlet pipe section 12 and the ratio of the lengths of the cylindrical pipe section 132 and the outlet pipe section 12, the silencing effect of the silencing pipe section 13 can be improved to a greater extent, the use feeling of a user is improved, and a more comfortable use environment is created; through reasonable data calculation, the production cost is reduced, and the production efficiency is improved.

According to the second aspect of the present invention, the air conditioner silencer assembly 100 includes any one of the above embodiments. It is understood that the air conditioner muffler assembly 100 installed in the air conditioner may be installed with the valve body 20 in both the inlet pipe section 11 and the outlet pipe section 12, or may be installed with the valve body 20 in one of them.

As shown in fig. 1 and 3, if the valve body 20 is installed at both ends of the muffler pipe section 13, the flowing refrigerant is filtered twice, and the flow rate is also adjusted twice, that is, the refrigerant flows into the muffler pipe section 13 from the inlet pipe section 11 of the air conditioner muffler assembly 100 through the filter screen 23, the valve seat 21, the valve core 22 and the fixing ring 30 of the inlet pipe section 11, and then flows out through the fixing ring 30, the valve core 22, the valve seat 21 and the filter screen 23 of the outlet pipe section 12 in sequence, so that the noise generated by the flow of the refrigerant can be further reduced, and the pressure difference between the front and the rear of the valve body 20 is adjusted, thereby realizing cooling and heating. If the valve body 20 is installed in only one of the inlet pipe section 11 or the outlet pipe section 12, the refrigerant flowing into the air conditioner muffler assembly 100 may first flow into the muffler pipe section 13 through the inlet pipe section 11, and then flow out through the valve body 20 to generate a pressure difference, so as to absorb or release heat at the moment of flowing out, thereby reasonably controlling the refrigerant flow.

Therefore, the air conditioner silencer assembly 100 with the valve body 20 at one end or the valve bodies 20 at two ends can be selected according to actual installation requirements, and the inlet pipe section 11, the outlet pipe section 12 and the silencing pipe section 13 are integrally connected, so that the problems of welding points and leakage of refrigerant are reduced; on the other hand, the assembly cost and the material cost are reduced, and the production efficiency and the product quality are improved.
