Embodiment 1

[0037]

[0038] Such as Figure 1a and Figure 1bAs shown, this embodiment provides a washing machine air duct noise reduction device, wherein the washing machine has a fan and an air duct 2; the noise reduction device 1 is arranged on the air duct 2 downstream of the fan, and includes an inlet 12, a flow guide cavity, and a sound absorption cavity 16 and the outlet 15; the inlet 12 communicates with the upper air outlet of the air duct 2, the first micro-perforated plate 121 is arranged at the inlet 12, and the first micro-perforated plate 121 has perforations with different apertures; the air flow in the air duct 2 is controlled by the first micro-perforated plate 121; The perforations of the micro-perforated plate 121 enter the noise reduction device 1. Due to the different apertures, on the one hand, the dander produced in the drying process of the washing machine can be filtered out, and on the other hand, the airflow noise can be reduced to varying degrees; As a result...

Embodiment 2

[0060] This embodiment provides a noise reduction device for an air duct of a washing machine, wherein the aperture diameter of the first micro-perforated plate and the second micro-perforated plate is ≤1mm, the plate thickness is ≤1mm, and the perforation rate ranges from 4% to 6%; the depth of the sound-absorbing chamber is 20mm-40mm.

Abstract

The invention provides a washing machine air duct noise reduction device and a washing machine with the same. The noise reduction device comprises an inlet, a flow guide cavity, a sound absorption cavity and an outlet, wherein a first micro-perforated plate is arranged at the inlet; the flow guide cavity is defined by a partition plate and is divided into an air inlet cavity and an air outlet cavity by a flow guide plate; the sound absorption cavity is defined by a partition plate and a second micro-perforated plate; sound absorption materials are arranged on the partition plates and can dissipate energy when being in contact with airflow, so that the purpose of noise reduction is achieved; the first micro-perforated plate and the second micro-perforated plate have perforations; the inlet communicates with the air inlet cavity, and the outlet communicates with the air outlet cavity; the airflow enters the air inlet cavity from the first micro-perforated plate, and flocks in the air inlet cavity are filtered; and the airflow in the air inlet cavity, the airflow in the sound absorption cavity and the airflow entering the air outlet cavity are in contact with sound absorption materials to complete three-stage noise reduction. According to the washing machine air duct noise reduction device, a labyrinth structure and different noise reduction materials are adopted, multi-stage noise reduction is completed, and the noise reduction effect is good; and the installation is convenient, and the user experience is high.

Description

technical field [0001] The invention relates to the field of laundry equipment, in particular to a washing machine air duct noise reduction device and a washing machine having the same. Background technique [0002] With the continuous development of washing machine technology, washing machines have more and more functions. For example, the popular drying function, while bringing convenience to users, the drying system itself will also bring various noise problems, which will directly affect the user experience. [0003] At present, the drying methods of washing machines are mainly electric heating type and heat pump type. The conventional electric heating drying system mainly includes a cylinder body and a drying component, wherein the drying component includes a heating air duct, a condensation air duct, a fan and a heating device. After being heated by the heating device, the air flow conveyed by the fan enters the cylinder body through the heating air duct, and exchange...
