Embodiment Construction

[0028] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] As mentioned above, due to the high-speed and high-power water pump applied to the large-flux water purifier, the water purifier produces huge noise, while the traditional sound-absorbing and noise-reducing sponge has poor durability, is prone to aging and damage, and the sound-absorbing effect is reduced. In view of this problem, the present invention proposes a water purifier with good durability, not easy to aging and damage, and good sound-absorbing effect.

[0030] The water purifier of the present invention includes a shell, a filter assembly and a porous sound-absorbing structure. The filter assembly is located in the casing, and the filter assembly includes a water pump and a filter element. The porous sound-absorbing structure is formed on the in...

Abstract

The invention discloses a water purifier. The water purifier includes a shell, a filter assembly and a porous sound-absorbing structure. The filter assembly is located in the casing, and the filter assembly includes a water pump and a filter element. The porous sound-absorbing structure is formed on the inner surface of the shell, and the hole openings of the porous sound-absorbing structure face the inside of the shell. The porous sound-absorbing structure of the water purifier has the characteristics of good durability, not easy to age and damage, and good sound-absorbing effect.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a water purifier. Background technique [0002] With the improvement of the performance of large-flux water purifiers, high-speed and high-power water pumps have begun to be applied to water purifiers, but they bring huge noise and seriously affect user experience. During the operation of the water pump, it is easy to inhale part of the air when the water pressure of the tap water pipe network is insufficient. Generate and burst, evoked noise. This kind of noise often has a high frequency, no obvious rules, and belongs to broadband noise (that is, the noise includes a wide frequency range, generally in the frequency band range of 1000-3000Hz). [0003] For the broadband noise of the water purifier, sound-absorbing cotton is traditionally used, and the sound-absorbing cotton is directly applied to the surface of the inner cavity of the water purifier, which can reduce the bro...
