[0039] Example 1
[0040] like Figures 1-4 As shown, a clothes dryer includes a housing 1, a roller is disposed inside the housing 1, and a rear cover 2 is disposed at the rear end of the roller. The rear cover 2 includes a rear cover plate 21, a sponge sound insulation layer 22 and a PU sound insulation layer 23.
[0041] The rear cover plate 21 is provided with an air duct groove 3. The PU sound insulation layer 23 and the sponge sound insulation layer 22 are arranged sequentially from front to back in the air duct groove 3. The sponge sound insulation layer 22 and the PU sound insulation layer 23 are installed between the rear cover plate 21 and the housing 1 to absorb the noise generated at the air duct groove 3 when the dryer is running.
[0042] The dryer described in this application can effectively absorb the noise generated in the air duct groove during operation by setting a sponge sound insulation layer 22 and a PU sound insulation layer 23 in the rear cover 2, thereby reducing the impact of noise on users and improving user experience.
[0043] As a preferred example of this application, the rear cover plate 21 includes a side plate 211, and a surrounding plate 212 is provided on the edge of the side plate 211. The side plate 211 and the surrounding plate 212 surround and form an air duct groove 3.
[0044] Specifically, this design improves the structural stability of the rear cover plate 21, better supports the weight of the dryer and vibrations during operation, and guides airflow to improve the efficiency of internal gas circulation.
[0045] As a preferred example of this application, the air duct 3 includes a drum duct 31 and an impeller duct 32, which are connected. The impeller duct 32 is used to accommodate the impeller 4 of the circulating fan, and the drum duct 31 is used to guide the air output by the circulating fan into the drum.
[0046] Specifically, this design facilitates the guidance of airflow generated by the circulating fan into the drum, improving gas circulation efficiency, thereby accelerating the drying process and enhancing the drying effect.
[0047] As a preferred example of this application, the sponge sound insulation layer 22 is provided with sound-absorbing holes 221.
[0048] Specifically, the sound holes 221 can cause the sound to scatter and interfere during propagation, reduce the intensity and frequency of the sound, and enhance the soundproofing effect. Meanwhile, the sound holes 221 can also reduce the weight of the sponge soundproofing layer 22 and achieve lightweight of the device.
[0049] As a preferred example of the present application, the sponge soundproofing layer 22 and the PU soundproofing layer 23 have the same shape.
[0050] Specifically, such a configuration can improve the assembly precision between the sponge soundproofing layer 22, the PU soundproofing layer 23, and the air duct slot 3, enhance the soundproofing effect, and facilitate production and processing of the sponge soundproofing layer 22 and the PU soundproofing layer 23.
[0051] As a preferred example of the present application, the thickness of the sponge soundproofing layer 22 is greater than the thickness of the PU soundproofing layer 23.
[0052] Specifically, by reasonably setting the thickness difference between the sponge soundproofing layer and the PU soundproofing layer, the cost can be optimized. The sponge soundproofing layer is mainly responsible for noise absorption, while the PU soundproofing layer is responsible for providing structural support and additional soundproofing effect. Such a design can ensure good soundproofing effect while reducing overall material cost, and achieve a balance between performance and cost.
[0053] As a preferred example of the present application, the edge of the surrounding plate 212 is provided with a folded edge 5, and the folded edge 5 is fixed together with the shell 1 by screws.
[0054] Specifically, such a configuration enhances the connection strength between the surrounding plate 212 and the shell 1, provides better structural stability, avoids loosening and vibration of the surrounding plate 212 during use, and facilitates installation and disassembly of the rear cover 2.
[0055] As a preferred example of the present application, the folded edge 5 is provided with an ear plate 51, and the ear plate 51 is fixed together with the shell 1 by screws.
[0056] Specifically, such a configuration enhances the connection strength between the folded edge 5 and the shell 1, makes the overall structure more stable, improves the carrying capacity of the folded edge 5, and facilitates installation and disassembly of the folded edge 5.
[0057] As a preferred example of the present application, the rear cover cover plate 21 is made of PP material.
[0058] Specifically, the PP material is light in quality, easy to carry and process, can reduce the overall weight of the clothes dryer, facilitate user movement, has a relatively low price, can reduce the manufacturing cost of the clothes dryer, improve market competitiveness, and has strong corrosion resistance, which can prolong the service life of the rear cover cover plate 21.
[0059] As a preferred example of the present application, a gap exists between the impeller 4 and the PU sound insulation layer 23.
[0060] Specifically, the gap ensures that the impeller 4 is not hindered during installation and can rotate freely during operation. The presence of the gap avoids direct contact between the impeller 4 and the sound insulation layer, thereby reducing friction and resistance, which helps to improve the operating efficiency and performance of the impeller and ensures its normal operation.
[0061] In summary, the laundry dryer described in the present application has the following advantages: 1. By providing a sponge sound insulation layer 22 and a PU sound insulation layer 23 in the rear cover 2, the noise generated during the operation of the laundry dryer can be greatly reduced, improving the user experience; 2.
