Specific embodiment
Hereinafter, the present invention will be described in detail with reference to various embodiments shown in the accompanying drawings.But these embodiments are not The limitation present invention, structure that those skilled in the art are made according to these embodiments, method or change functionally It changes and is included within the scope of protection of the present invention.
The term of the representation space relative position used herein such as "upper", " top ", "lower", " lower section " is for just A unit as shown in the drawings or feature are described relative to another unit or the relationship of feature in the purpose of explanation.It is empty Between the term of relative position can be intended to include different direction of the equipment in use or work other than orientation as shown in the figure. For example, the unit for being described as being located at other units or feature " below " or " under " will if the equipment in figure overturn Positioned at other units or feature " top ".Therefore, exemplary term " lower section " can include above and below both orientation.If It is standby to be otherwise directed (be rotated by 90 ° or other directions), and be interpreted accordingly used herein with space correlation Language is described.
Also, it should be understood that although term first, second etc. can be used to describe herein various elements or Structure, but these are described object and should not be limited by these terms.These terms are only used to by these description objects that This is distinguished.For example, the first bottom surface can be referred to as the second bottom surface, and similarly the second bottom surface can also be referred to as the first bottom Face, this protection scope without departing from the application.
The embodiment of the invention provides a kind of silencing means, as shown in Figure 1, comprising:
Bottom plate 11, at least two cylinders 12 being set on bottom plate 11, and any two cylinder is mutually isolated;The column Body 12 is internally provided with cavity, and the first bottom surface of cylinder 12 is connected to the bottom plate 11, and the bottom plate 11 seals the cavity; The second bottom surface far from the bottom plate 11 in the cylinder 12 is the opening being connected with the cavity.Here, any two Cylinder 12 is mutually isolated, i.e., does not contact between these cylinders 12, and there is each cylinder 12 one to be open far from bottom plate 11 Cavity, i.e. sound enter in cavity by the opening, go out again from opening later;It is understood that the silencing means is One standing wave tube structure, which can be changed to standing wave by traveling wave for noise, so as to reduce energy transmission, and Reduce noise, achievees the effect that noise reduction.And it since cylinder 12 is internally provided with cavity, and is not contacted between cylinder 12, this disappears Mixer does not influence the heat dissipation of refrigerator.
Optionally, cylinder 12 can be in cylindrical shape, i.e. cavity in cylinder 12 is in cylindrical shape, and opening is also in circle Shape, and the axial direction of the cylindrical body can be perpendicular to bottom plate 11;The area of the opening of cylinder 12 can be 0.1cm2-25cm2, cylinder 12 height can be 1cm-20cm.
Preferably, the volume of the cavity at least two cylinder 12 is not all equal.Here, at least there are two cavitys 12 Volume be unequal;It is understood that the volume of the cavity in cylinder 12 can determine what the cylinder 12 can be eliminated Therefore the frequency band of sound can allow the silencing means to have wider noise reduction frequency by adjusting the volume of different cavitys 12 Section.
Optionally, the volume of the cavity at least two cylinder 12 is unequal.Here, any two cavity 12 Volume is all unequal.Here it is possible to understand, the volume of the cavity in cylinder 12 can determine what the cylinder 12 can be eliminated The frequency band of sound, i.e., different cylinders 12 have different noise reduction frequency bands therefore can be by adjusting different cavitys 12 Volume allows the silencing means to have wider noise reduction frequency.
