Embodiment 1

[0027] Such as figure 1 As shown, in this embodiment, a sound-absorbing structure suitable for the drying air duct of the washing machine is disclosed. The sound-absorbing structure can be arranged on the drying air duct located downstream of the fan. The air outlet is connected, and the air outlet of the drying air duct is connected with the drying barrel, and the noise in the air duct and the noise of the fan can be eliminated by being arranged at this place. Specifically, the noise reduction structure includes: an outwardly protruding cavity formed on the upper wall of the drying air duct, a micro-perforated plate 1 sealed at the mouth of the cavity, and a micro-perforated plate located at the rear side of the micro-perforated plate (cavity One side inside) and the sound insulation layer 2 laid on the inner wall of the cavity at a predetermined distance from the micro-perforated plate.

[0028] In this embodiment, the laying direction of the micro-perforated plates is para...

Embodiment 2

[0039]In this embodiment, a washing machine with noise reduction function is disclosed. The washing machine includes: a drying air duct, a fan and a drying drum, wherein the drying fan and the drying drum are connected through the drying air duct, and the drying air duct adopts The sound-absorbing structure in embodiment 1.

[0040] During the drying process of the washing machine, the fan of the drying system is always running at high speed, and the noise of the fan motor and the air flow noise of the air duct are particularly prominent. The technical solution in the present invention starts to improve the structure of the drying air duct, and adopts new sound-absorbing materials to reduce the noise of the drying system from the transmission path and improve the quiet comfort of the whole machine.

[0041] The present invention will be further described in detail below in combination with specific embodiments.

[0042] Such as figure 1 As shown, the drying air duct in the w...

Abstract

The invention provides a silencing structure suitable for a drying air duct of a washing machine. The silencing structure is arranged on the drying air duct located at the downstream part of a fan; anair inlet of the drying air duct is connected with an air outlet of the fan; an air outlet of the drying air duct is connected with a drying barrel; the silencing structure comprises an outwards protruding cavity formed in the upper wall surface of the drying air duct, a micro-perforated plate sealed at a cavity opening of the cavity and a sound insulation layer located on the rear side of the micro-perforated plate and laid on the inner wall of the cavity in a manner of keeping a preset interval from the micro-perforated plate. The invention further provides the washing machine provided withthe silencing structure.

Description

technical field [0001] The invention relates to a noise reduction technology for an air duct of a washing machine, in particular to a noise reduction structure for a drying air duct of a washing machine and a washing machine. Background technique [0002] With the continuous development of washing machine technology, the washing machine has more and more functions at present. While bringing convenience to users, problems such as noise and vibration also follow. For example, when the washing machine enters the drying stage after completing the dehydration process, the drum is in a low-speed state, and the noise generated by the drying system is the main noise source of the whole machine. [0003] Resonant cavity noise reduction is a commonly used and effective noise reduction measure in engineering. It has been widely used in large-scale air ducts, exhaust pipes and other pipeline installations. The resonant cavity and sound-absorbing materials are combined to form a cavity ...
