[0001] The present disclosure relates to the technical field of clothing processing equipment, and in particular to a silencer, a drying module and clothing processing equipment. Background Art

[0002] With the continuous pursuit of quality of life, clothes processing equipment equipped with drying function has gradually become popular. Specifically, the fan introduces external air into the dryer to heat and dry the clothes. However, the fan will generate a lot of pneumatic noise when working, which is transmitted through the air inlet of the air inlet pipe, affecting the user experience. Utility Model Content

[0003] In order to overcome the problems existing in the related art, the present disclosure provides a silencing device, a drying module and a clothes processing device.

[0004] According to a first aspect of an embodiment of the present disclosure, a silencer is provided, which is suitable for installation at an air inlet of an air inlet duct, the silencer comprising a cover body arranged at the air inlet, and a sound absorbing layer is arranged on an inner wall of the cover body facing the air inlet.

[0005] Optionally, the cover body is constructed in a hollow hemispherical shape.

[0006] Optionally, the sound-absorbing layer is a sound-absorbing foam arranged on the inner wall of the cover body.

[0007] Optionally, the thickness of the sound absorbing layer ranges from 5 mm to 15 mm.

[0008] Optionally, the silencer device further comprises a mounting member disposed between the cover body and an outer wall of the air inlet duct, and the mounting member is detachably connected to the outer wall of the air inlet duct and the cover body, respectively.

[0009] Optionally, the mounting piece is constructed in a sleeve shape, wherein the inner wall of the mounting piece is provided with an internal thread suitable for cooperating with the outer wall of the air inlet duct, the outer wall of the mounting piece is provided with a plurality of bosses, and the cover body is provided with a mounting hole whose position corresponds to the bosses for a fastener to pass through.

[0010] Optionally, a plurality of the bosses are arranged at equal intervals along the circumference of the mounting member.

[0011] According to the second aspect of the embodiment of the present disclosure, a drying module is provided, comprising a drying chamber and an air inlet duct and an air outlet duct respectively connected to the drying chamber, a silencer is provided at the air inlet of the air inlet duct, and the silencer is any one of the silencers described above, wherein an air inlet gap is formed between the inner wall of the cover body and the air inlet.

[0012] Optionally, the silencer is detachably arranged at the air inlet.

[0013] According to a third aspect of an embodiment of the present disclosure, there is provided a clothing processing device comprising the above-mentioned drying module.

[0014] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: the silencer provided by the present disclosure is suitable for installation at the air inlet of the air inlet duct. When the aerodynamic noise generated by the fan is transmitted outward to the air inlet, part of the noise is directly absorbed by the sound-absorbing layer on the inner wall of the cover, and another part of the noise is reflected by the inner wall of the cover and then absorbed by the sound-absorbing layer, thereby minimizing the amount of noise transmitted outward from the air inlet. In addition, since the silencer is arranged at the air inlet position, when the external air enters the air inlet duct under the action of the fan, it is not blown directly in along the axial direction of the air inlet duct, but changes the direction of the air intake, which is beneficial to reduce the direct impact of the external air on the air inlet, thereby reducing aerodynamic noise and improving user experience.

[0022] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0023] Unless otherwise specified, directional words such as "upper, lower, left, right" are defined according to the directions indicated in the corresponding drawings, while "inner" and "outer" refer to the inner and outer contours of the corresponding components themselves. In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another, and do not have order and importance.

[0024] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0025] like Figures 1 to 3 As shown, an exemplary embodiment of the present disclosure provides a muffler 1, which is suitable for being installed at the air inlet 21 of the air inlet duct 2, for example, suitable for being installed at the air inlet 21 of the air inlet duct 2 of the drying module. Usually, a fan 3 is arranged in the air inlet duct 2, and when the fan 3 is working, negative pressure is generated to introduce external air into the air inlet duct 2 through the air inlet 21. The fan 3 is generally an axial flow fan, which is easy to generate noise when working, and the noise is mainly aerodynamic noise, such as Figure 2 As shown by the dashed arrow, the pneumatic noise propagates outward through the air inlet 21 of the air inlet duct 2, affecting the user experience.

[0026] Based on the above technical problems, the silencer 1 provided by the present disclosure includes a cover body 11 arranged at the air inlet 21, and a sound absorbing layer 12 is arranged on the inner wall of the cover body 11 facing the air inlet 21. In this way, when the aerodynamic noise generated by the fan 3 when working is transmitted outward to the air inlet 21, part of the noise is directly absorbed by the sound absorbing layer 12 on the inner wall of the cover body 11, and the other part of the noise passes through the sound absorbing layer 12 and is absorbed by the sound absorbing layer 12 after being reflected by the inner wall of the cover body 11, that is, after the double sound absorption process of being directly absorbed by the sound absorbing layer 12 and being absorbed by the sound absorbing layer 12 after being reflected by the inner wall of the cover body 11, the amount of noise transmitted outward from the air inlet can be minimized or even completely reduced.

[0027] In addition, since the silencer 1 provided by the present disclosure is arranged at the air inlet 21, as Figure 2The solid arrow in the middle shows the path of the external air. The external air enters the air inlet duct 2 through the air inlet gap between the inner wall of the cover body 11 and the air inlet port 21. More specifically, the external air enters from the outer periphery of the cover body 11 and is collected inside the cover body 11 and then enters the air inlet duct 2, thereby changing the air inlet direction of the external air. This change in direction is mainly to distinguish it from the method in the related art where the external air directly enters the air inlet duct 2 along the axial direction.

[0028] External air enters the air inlet 2 through the air inlet 21, and the aerodynamic noise propagating outward is propagated from the air inlet 2 to the air inlet 21. Considering that the direct impact of external air on the air inlet 21 during the process of being introduced into the air inlet 2 is also one of the sources of noise, the present disclosure sets the silencer 1 at the position of the air inlet 21, forcing the wind direction to change and reducing the acceleration of the external air, which is conducive to slowing down the direct impact on the air inlet 21, so as to achieve the purpose of reducing noise.

[0029] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: the silencer 1 provided by the present disclosure is suitable for being installed at the air inlet 21 of the air inlet duct 2. When the aerodynamic noise generated by the fan 3 is transmitted outward to the air inlet, part of the noise is directly absorbed by the sound-absorbing layer 12 on the inner wall of the cover body 11, and another part of the noise is reflected by the inner wall of the cover body 11 and absorbed by the sound-absorbing layer 12, thereby minimizing the amount of noise transmitted outward from the air inlet. In addition, since the silencer is arranged at the air inlet 21, when the external air enters the air inlet duct 2 under the action of the fan 3, it is not blown directly in along the axial direction of the air inlet duct 2, but the direction of the air intake is changed, which is beneficial to reduce the direct impact of the external air on the air inlet 21, thereby reducing the aerodynamic noise and improving the user experience.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the cover body 11 is constructed as an air hemisphere. This hollow hemispherical cover body 11, on the one hand, can provide a larger cover range and minimize the possibility of noise escape; on the other hand, the inner wall of the cover body 11 is in an arc shape, which is more conducive to multiple reflections of the incident noise, thereby absorbing the noise to the greatest extent. Of course, in some other embodiments, the cover body 11 constructed in other shapes can also be applied to the silencer 1 of the present disclosure to solve the problem of silencer, or the inner wall of the cover body 11 is constructed into a non-smooth plane such as a corrugated shape to further improve the sound absorption effect.

[0031] The sound-absorbing layer 12 may be a sound-absorbing foam disposed on the inner wall of the cover body 11. This sound-absorbing material is light in weight and can provide a good sound-absorbing effect, and is an ideal sound-absorbing material. The sound-absorbing foam may be disposed on the inner wall of the cover body 11 by, for example, bonding. In addition, the sound-absorbing layer 12 may also be, for example, a sound-absorbing coating coated on the inner wall of the cover body 11, which can also achieve the effect of absorbing noise, and the disclosure will not go into details. The entire inner wall of the cover body 11 may be provided with a sound-absorbing layer 12, or on the basis of leaving an installation space, for example, leaving an installation space for the convex column 131 to be introduced later, a sound-absorbing layer 12 may be disposed at other positions. The sound-absorbing layer 12 may be a single layer or multiple layers of sound-absorbing layers 12 stacked. Optionally, the thickness range of the sound-absorbing layer 12 may be 5 mm to 15 mm. The sound-absorbing layer 12 within this thickness range may not only meet the sound-absorbing effect well, but also will not excessively occupy the internal space formed by the cover body 11 and affect the introduction of external air.

[0032] like Figure 1 and Figure 2 As shown, the silencer 1 provided by the present disclosure also includes a mounting member 13 disposed between the cover body 11 and the outer wall of the air inlet duct 2, and the mounting member 13 is detachably connected to the outer wall of the air inlet duct 2 and the cover body 11, respectively. That is, the cover body 11 is detachably mounted on the air inlet duct 2 through the mounting member 13, so that when the silencer 1 is maintained or replaced, it is only necessary to replace the cover body 11 or replace the cover body 11 and the mounting member 13 at the same time, without having to replace the entire air inlet duct 2, which is beneficial to saving costs and improving work efficiency. In addition, the silencer 1 is detachable, so that the silencer 1 can be added on the basis of the existing air inlet duct 2 without having to redesign the air inlet duct 2 separately, and has high versatility.

[0033] In some embodiments, the mounting member 13 is configured as a sleeve, wherein the inner wall of the mounting member 13 is provided with an internal thread 132 suitable for matching with the outer wall of the air inlet duct 2, the outer wall of the mounting member 13 is provided with a plurality of bosses 131, and the cover body 11 is provided with a mounting hole 111 corresponding to the bosses 131 for the fastener to pass through. Specifically, the outer wall of the air inlet duct 2 is provided with an external thread 22, and the sleeve-shaped mounting member 13 is provided with an internal thread 132. When assembling, it is only necessary to tighten the mounting member 13 axially onto the air inlet duct 2. The boss 131 outside the mounting member 13, that is, the boss 131 is supported between the mounting member 13 and the cover body 11, wherein a threaded hole is provided at the end of the boss 131 facing the inner wall of the cover body 11, and the cover body 11 is provided with a mounting hole 111 corresponding to the boss 131 for the fastener to pass through. When assembling, it is only necessary to pass the fastener through the mounting hole 111 and the threaded hole in sequence.

[0034] Optionally, a plurality of bosses 131 are arranged at equal intervals along the circumference of the mounting member 13. The plurality of bosses 131 are conducive to improving the connection strength between the cover body 11 and the mounting member 13, and the equidistant arrangement of the bosses 131 is also conducive to providing uniform connection points to avoid stress concentration. In addition, in addition to the aforementioned threaded connection between the mounting member 13 and the air inlet duct 2, the sleeve-shaped mounting member 13 and the air inlet duct 2 are connected by interference fit or the mounting member 13 is integrally arranged on the air inlet duct 2 by welding, etc., so that only the cover body 11 needs to be replaced during maintenance.

[0035] According to a second aspect of the embodiment of the present disclosure, Figure 3 As shown, a drying module is also provided, which can be configured in an independent clothes dryer or in a clothes processing device with clothes drying function, such as a drum washing machine integrating washing and drying.

[0036] Specifically, the drying module includes a drying chamber 4 and an air inlet duct 2 and an air outlet duct 5 respectively connected to the drying chamber 4. The fan 3 can be arranged in the air inlet duct 2. A silencer 1 is arranged at the air inlet 21 of the air inlet duct 2. The silencer 1 is any of the above-mentioned silencers and has all its beneficial effects, which will not be repeated here. Among them, an air inlet gap is formed between the inner wall of the cover body 11 and the air inlet 21. The drying chamber 4 can be, for example, the drum of a drum washing machine. Specifically, under the action of the fan 3, the external air enters the air inlet duct 2 through the air inlet 21, and then enters the drying chamber 4 to heat and dry the clothes, and finally is discharged from the air outlet 51 of the air outlet duct 5.

[0037] Optionally, the silencer 1 is detachably arranged at the air inlet 21. In this way, when the silencer 1 is maintained or replaced, only the silencer 1 needs to be replaced without replacing the entire air inlet pipeline 2, which is conducive to saving costs and improving work efficiency. In addition, the silencer 1 is detachable, so that the silencer 1 can be added on the basis of the existing air inlet pipeline 2 without having to redesign the air inlet pipeline 2 separately, and the versatility is high.

[0038] According to a third aspect of the embodiments of the present disclosure, there is also provided a clothing processing device, comprising the above-mentioned drying module. The clothing processing device may be, for example, a drum-type washing machine integrating washing and drying.
