Abstract

The invention provides a water purifier. The water purifier comprises a casing, a water pump and a sound-absorbing device, wherein the water pump is arranged in the casing; the sound-absorbing deviceis arranged in the casing and near the water pump; the sound-absorbing device comprises a sound-absorbing shell and a microperforated panel; the sound-absorbing shell is provided with an opening, andthe opening faces the water pump; the microperforated panel covers the opening of the sound-absorbing shell; a through hole in the microperforated panel is communicated with a cavity of the sound-absorbing shell. The water purifier of the invention is characterized in that when an air unit in the through hole in the microperforated panel vibrates, energy of a sound field is dispersed, so that noise produced when the water pump vibrates is reduced and the purpose of reducing noise is achieved. Compared with sound-absorbing cotton, the microperforated panel is much more environmentally friendly;when the microperforated panel is installed on the water purifier, no harm is caused to human health; at the same time, the microperforated panel does not need to be connected through glue, and thus,reliability is high and stability is great; in addition, when the microperforated panel absorbs sounds, heat dissipation of the water pump is not affected, thereby avoiding the problem that the waterpump can not work normally because of over high temperature increase.

Description

technical field [0001] The invention relates to the technical field of purification equipment, 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 diaphragm pumps have begun to be applied to water purifiers, but they bring huge noise and vibration, which seriously affect the user experience. In the prior art, for broadband noise reduction of water purifiers, sound-absorbing cotton is usually used. [0003] Although sound-absorbing cotton has a certain noise reduction function, its application in water purifiers has the following disadvantages: the existing sound-absorbing cotton is not environmentally friendly, and its application in water purifiers is likely to cause certain harm to human health; The glue is connected to the shell of the water purifier pump or near it. On the one hand, the glue itself is not environmentally friendly, and on the other hand, the reli...
