Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Terms such as "upper," "above," "lower," "below," and the like, used herein to denote relative spatial positions, are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Also, it should be understood that, although the terms first, second, etc. may be used herein to describe various elements or structures, these described elements should not be limited by these terms. These terms are only used to distinguish these descriptive objects from one another. For example, the first sliding stop may be referred to as the second sliding stop, and similarly the second sliding stop may also be referred to as the first sliding stop, without departing from the scope of protection of the present application.
The embodiment of the invention provides a compressor bin 1 for a refrigerator, as shown in fig. 2, a plurality of sharp corners 13 facing the inside of the compressor bin 1 are arranged on a wall plate 12 of the compressor bin 1, the sharp corners 13 are hollow, the inside space of the sharp corners is filled with a foaming material, and a plurality of holes 131 communicated with the inside space are arranged on the sharp corners 13.
In a conventional refrigerator having a refrigerating compartment at the upper side and a freezing compartment at the lower side, the compressor housing 1 is usually located at the rear of the freezing compartment, the compressor 11, the water pan, the pipes for flowing the refrigerant, and the like are usually installed in the compressor housing 1, and the compressor housing 1 is usually wrapped with a metal plate, i.e., a wall plate 12. Fig. 2 shows only one tip 12 provided on the wall plate 12, and in practical use, the number of the tips 12 can be flexibly adjusted according to needs, and the positional relationship of the respective tips 12 can be adjusted, for example: at the location on the wall close to the compressor 11, it is possible to dispense with the tip or to reduce the size 6 of the tip due to space restrictions; the wall plate 12 at the back of the refrigerator is generally provided with a vent hole, so that it is inconvenient to provide a tip, and thus, no or only a small amount of the tip may be provided. The tip 12 may be tapered, wedge-shaped, or the like
It can be seen that the foaming material in the inner space of the plurality of tips 13 forms a plurality of splits after foaming is completed, and the foaming material has certain noise elimination capability, so that a special sound absorber is formed and can almost completely absorb sound waves incident to the surface of the sound absorber; the section of the pointed foaming material is gradually enlarged from the pointed end to enable the section to be matched with the characteristic impedance of air, and therefore the incident sound waves are almost absorbed without reflection. In the compressor housing 1 of the present embodiment, the pointed foam material is wrapped in the tip portion, and the tip portion 13 is provided with a plurality of holes communicating with the internal space, so that a part of the noise can enter the pointed foam material along the holes and be absorbed by the foam material, while another part of the noise can be reflected by the tip portion 13 to other tip portions 13, and a part of the noise enters the foam material through the holes, so as to reciprocate until the noise is eliminated. The multi-split microphone can effectively remove high-frequency components in noise, and for most people, the sound quality of high-frequency (such as the frequency of 2000 Hz-5000 Hz) sound is quite harsh, namely the sound quality is not high, so that the multi-split microphone can effectively remove the high-frequency noise, and the sound quality of the noise is improved.
Preferably, the tip 13 is tapered.
Preferably, the tip 13 is a wedge-shaped wedge; here in fig. 2, the tip 13 is a wedge-shaped wedge.
Preferably, said tip 13 is in the form of a flat-head wedge or a pointed wedge.
Preferably, the tip 13 is made of the same material as the wall plate 12. In the compressor chamber 1 of the refrigerator, there are a compressor, a water receiving tray, various pipes for flowing a refrigerant, etc., which are easily generating moisture, so that, when a material for manufacturing the wall plate 12 is selected, a material for preventing corrosion is generally used, the tip portion 13 is also required to have a capability of preventing corrosion, and further, the tip portion 13 is made of the same material as the wall plate 12, which facilitates manufacturing and reduces production cost.
Preferably, the holes are circular and 1mm in diameter. In the process of foaming treatment, the foaming material is likely to seep out of the holes, and in the long-term practice of the inventor, the inventor finds that when the holes are circular and have the diameter of 1mm, the seepage of the foaming material can be effectively prevented without influencing the noise elimination; it can be understood that when the hole is intensive more, the noise enters into the foaming material in the point portion more easily, also can eliminate the noise more easily, but there is steam in the compressor storehouse 1, steam can enter into the foaming material along the hole, this can cause the injury to the refrigerator, consequently, the intensity in hole also needs a degree, through the long-term experiment of inventor, discover when the centre of a circle interval of two adjacent holes is 2mm, both can effectual noise elimination, can effectually prevent again that steam from entering into the foaming material in the point portion.
Preferably, the portion of the wall plate 12 connected to the tip portion 13 is of an open structure, and the portion of the tip portion 13 connected to the wall plate 12 is of an open structure. After the compressor housing 1 is installed in the refrigerator body, a space for containing a foaming material is left outside the compressor housing 1, and since the internal space of the tip portion 13 is communicated with the space for containing the foaming material, the foaming material outside the compressor housing 1 automatically flows into the internal space of the tip portion 13 during foaming processing, and the internal space is filled. The cost is low because no additional operation is needed.
Preferably, the foaming material is polyurethane. The polyurethane is not only a heat-insulating material with good performance, but also has certain noise elimination performance.
Preferably, the tip part is in the shape of an isosceles cone, the base width is 24mm, and the height from the base to the cone top is 43 mm. The cutoff frequency of the wedge is the minimum frequency it can absorb, and the formula is: base width = sound speed ÷ (base-to-cone top height × 4), the sound quality of high-frequency sounds with a typical frequency of 2000Hz to 5000Hz tends to be harsh, and therefore, the cutoff frequency of the wedge is 2000Hz, then base width =340/2000/4=42.5mm ≈ 43 mm. So that high frequency sounds having a frequency higher than 2000Hz can be effectively eliminated.
The steps in producing a refrigerator using the compressor compartment 1 of the present embodiment generally include the steps of:
step 1: providing the above-mentioned compressor bin 1;
step 2: the compressor bin 2 is arranged in a refrigerator body;
and step 3: and filling the foaming material into the relevant part of the refrigerator body and the inner space of the wedge-shaped wedge 13 for foaming operation.
From step 1 to step 3, the step of producing a refrigerator based on the compressor housing 1 is identical to the step of producing a refrigerator based on the existing compressor housing 1, and when the foaming material is filled in step 3, the foaming material automatically enters into the inner space of the wedge-shaped wedge 13,
the second embodiment of the invention provides a refrigerator which is provided with the compressor bin for the refrigerator provided by the first embodiment.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
