Abstract
The invention discloses a household electric appliance, which comprises a box body. A motor and a cavity are arranged in the box body, the motor is in transmission connection with the cavity and can drive the cavity to move, the box body has a bottom, and a thin plate distributed with through holes is arranged at the inside of the box body or replaces the bottom of the box body, wherein a certain distance is reserved between the thin plate at the inside of the box body and the box body, and a certain distance is reserved between the thin plate replacing the bottom of the box body and the ground. According to the structure, a sound absorbing layer which can absorb noise inside a washing machine is formed by the perforated thin plate and a gap between the thin plate and the box body or the ground together; and compared with the conventional sound absorbing cotton, the perforated thin plate has the advantages of sound absorption capacity, water and humidity resistance, mildew resistance, moth resistance, fire prevention, high temperature resistance, corrosion resistance, cleanness and no pollution, capacity of bearing high-speed airflow impact and the like.
Description
[technical field]
The present invention relates to a kind of household electrical appliance, these household electrical appliance have a casing, and motor and a cavity are housed in the casing, and motor is connected with cavity and can drives cavity motion, and loaded article is carried out relevant treatment in cavity, for example wash, oven dry etc.; The invention particularly relates to and have the household electrical appliance that reduce self noise function.
[background technology]
Household electrical appliance especially have the household electrical appliance that motor is used to drive, and for example often there are bigger noise in washing machine, dryer, clothes washer-dryer and dish-washing machine etc. in running.In washing machine inside, the main source of noise is a motor.If the motor that washing machine uses is to exchange series excited machine, then noise is mainly derived from following components: carbon brush contacts the sound of uttering long and high-pitched sounds that produces with commutator; Rotor is recessed at the air force noise of the formation under the rotation at a high speed; Speed measuring motor produces electromagnetic noise; Bearing noise etc.These noises have a common ground, and their frequency all is associated with rotating speed of motor, and all belong to the medium-high frequency noise.
Most of above-mentioned household electrical appliance, for example washing machine all is to paste acoustical cotton by the inside that comprises bottom half in casing to reach the purpose that absorbs noise.Use acoustical cotton to have certain shortcoming: because the general humidity of working environment of these household electrical appliance is bigger, simultaneously may have water in running spills and drips on the acoustical cotton in cavity or pipeline, so be easy to breed bacteria on the acoustical cotton, and go mouldy easily after absorbing moisture.
[summary of the invention]
The object of the present invention is to provide a kind of have be easy to make, and overcome the household electrical appliance of the sound arrester of the above-mentioned defective that exists in the prior art.
In order to realize above purpose, the household electrical appliance that provided comprise a casing, a motor and a cavity are arranged in the casing, motor and cavity are in transmission connection and can drive the cavity motion, described casing has a bottom, described cavity has an opening, a door assembly is loaded on the described casing, but the opening of closed cavity, the thin plate of the through hole that distributing is loaded on the inboard of described casing or replaces the bottom of casing, wherein being loaded between the thin plate of described box inside and the described casing has a segment distance, replaces the thin plate and the ground of bottom half that one segment distance is arranged.According to above structure, the thin plate of perforation and and casing or ground between the space formed sound absorbing layer jointly, can absorb the noise of washing machine inside, the high frequency noise that causes by motor especially, thereby reach the function that reduces noise.In addition, microperforated panel can use materials such as aluminium sheet, steel plate, galvanized sheet, corrosion resistant plate, plastic plate to make, and is not subjected to the restriction of material basically, and makes such thin plate and only need punch on sheet material, and technology is simple; The most important thing is, than traditional acoustical cotton, the perforation thin plate when guaranteeing acoustical absorptivity, have not water funk again and moisture, not mould, do not eat into, fire prevention, high temperature resistant, corrosion-resistant, cleanliness without any pollution, can bear advantages such as high velocity air impact.
Preferably, described through hole evenly distributes, so can absorb noise more equably.
Preferably, the aperture of described through hole is identical, and less than 1 millimeter.
Preferably, the punching rate of described thin plate is between 1% to 5%.
Preferably, described through hole is round.
Preferably, described gauge of sheet is less than or equal to 1 millimeter.
Preferably, the distance between described thin plate and casing or described thin plate and the ground is 5 to 20 centimetres.
[description of drawings]
Fig. 1 is a kind of schematic perspective view of household electrical appliance;
Fig. 2 is the schematic cross-section of the thin plate of perforation.
[specific embodiment]
As shown in Figure 1, household electrical appliance 1 have a casing 2, and this casing 2 is made up of sidewall 3, top cover 4 and bottom 5.A motor 6 and a cavity 7 are arranged in the casing 2, and motor 6 is in transmission connection with cavity 7 and can drives cavity 7 motions.Cavity 7 has 8, one door assemblies 9 of an opening to be loaded on the described casing 2, but the opening 8 of closed cavity 7.
A thin plate 10 is loaded on the inboard of the bottom 5 of casing 2, and a large amount of through holes 11 are distributing on the thin plate 10.Thin plate 10 shown in Figure 1 is loaded on 5 inboard, bottom and only is a kind of real-time mode wherein.In other embodiments, thin plate 10 can be loaded on one or more surfaces inboard of 2 of casings, perhaps makes thin plate 10 replace the bottom 5 of casings 2, at one or more surfaces of casing 2 inboards thin plate 10 is installed when perhaps also can make thin plate 10 replace bottom half 5.These other embodiments are expression in the accompanying drawings not, but is understood that according to above description.As shown in Figure 2, be loaded on casing 2 inboards thin plate 10 should and casing 2 between leave a segment distance D, replace the thin plate 10 of bottom half 5 a segment distance D to be arranged with ground 12, in this distance D, do not fill out any sound-absorbing material, so promptly constituted microperforated panel soundabsorbing construction, noise in the casing 2 can be absorbed by such sound absorption structure, can not impact surrounding environment.Except the above mode, also can adopt bilayer or multilayer microperforated panel version, can reach acoustically effective in various degree.
" Chinese science ", 1975,18 (3): the principle to microperforated panel soundabsorbing construction in " the theoretical and design of microperforated panel soundabsorbing construction " literary composition of 38-50 has gem-pure elaboration, can be used as supplementary notes of the present invention and reference.
In an embodiment of the present invention, preferably, described through hole 11 is circular, evenly distributes, and punching rate is between 1～5%, and aperture d is identical, all less than 1 millimeter; The thickness t of thin plate 10 is less than or equal to 1 millimeter; Distance D between thin plate 10 and casing 2 or the ground 12 is 5 to 20 centimetres.
