Description

Technical Field

[0001] The invention relates to the technical field of compressors, and in particular to a compressor pump body structure, a compressor and an air conditioner. Background Art

[0002] like Figure 1-2 In the existing pump body assembly with two upper and lower silencers, the silencer chambers of the upper and lower silencers are generally overlapped. On the one hand, the overlapped setting of the silencer chambers causes the upper and lower silencer screw holes to overlap, so that the upper and lower screws simultaneously apply screw force to a certain fixed position of a pump body part, increasing the deformation of the part. On the other hand, the overlapped setting of the silencer chambers causes the upper and lower silencer chambers to radiate noise at a fixed angle and in a fixed direction at the same time. The superposition of the noise radiation of the two can easily cause the compressor to generate excessive noise in a fixed direction.

[0003] Since the upper and lower silencer chambers of the compressor in the prior art are overlapped, the upper and lower silencer chambers simultaneously radiate noise in a fixed angle and direction. The superposition of the noise radiations of the two can easily lead to technical problems such as the compressor generating excessive noise in a fixed direction. Therefore, the present invention studies and designs a compressor pump body structure, a compressor and an air conditioner. Summary of the invention

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0060] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description.

[0063] like Figure 3-14As shown, the present invention provides a compressor pump body structure, which includes:

[0064] A first muffler 1 and a second muffler 2, wherein the first muffler 1 comprises at least one first muffler chamber 3, and the second muffler 2 comprises at least one second muffler chamber 4;

[0065] In the axial projection plane of the pump body structure, the first muffler chamber 3 and the second muffler chamber 4 do not overlap, or the first muffler chamber 3 and the second muffler chamber 4 have partial structural overlap.

[0066] The present invention can effectively avoid the upper and lower silencer chambers from simultaneously radiating noise in a fixed angle and direction by setting the first silencer chamber of the first silencer and the second silencer chamber of the second silencer to be completely non-overlapping or partially overlapping in the axial direction, thereby reducing the superposition effect of the two, and avoiding the situation where the compressor generates excessive noise in a fixed direction, and effectively solves the problem that the upper and lower silencer chambers of the existing compressor are overlapped, so that the upper and lower silencer chambers simultaneously radiate noise in a fixed angle and direction, and the noise radiation of the two is superimposed, resulting in the compressor generating excessive noise in a fixed direction; and the present invention can also effectively realize the offset setting of the upper and lower silencer locking screws through the staggered setting of the upper and lower silencer chambers, thereby avoiding the upper and lower screws from simultaneously applying screw force to a fixed position of a pump body part, reducing part deformation, and solving the problem that the upper and lower silencer screw holes are also overlapped due to the overlapped setting of the silencer chambers, so that the upper and lower screws simultaneously apply screw force to a fixed position of a pump body part, thereby increasing part deformation.

[0067] In some embodiments,

[0068] When there is no overlap or partial overlap between the first soundproofing chamber 3 and the second soundproofing chamber 4, the first soundproofing chamber 3 has a first center line 5, and the first soundproofing chamber 3 is symmetrical relative to the first center line 5, the second soundproofing chamber 4 has a second center line 6, and the second soundproofing chamber 4 is symmetrical relative to the second center line 6, and the first center line 5 and the second center line 6 do not overlap, forming a misalignment.

[0069] This is the preferred structural form of the first and second muffler chambers of the present invention, that is, both are regular structures, that is, symmetrical structures in the axial projection plane, and are symmetrically arranged relative to the first center line and the second center line respectively. The present invention further has a staggered arrangement of the center lines of the first and second muffler chambers of the regular structure, which can further avoid the upper and lower muffler chambers from simultaneously radiating noise in a fixed angle and direction, reduce the superposition effect of the two, and avoid the compressor from generating excessive noise in a fixed direction. It effectively solves the problem that the upper and lower muffler chambers of the existing compressor are overlapped, so that the upper and lower muffler chambers generate noise radiation in a fixed angle and direction at the same time, and the noise radiation of the two is superimposed, resulting in the compressor generating excessive noise in a fixed direction; and the present invention can also effectively realize the staggered arrangement of the upper and lower muffler locking screws through the staggered arrangement of the upper and lower muffler chambers, thereby avoiding the upper and lower screws from simultaneously applying screw force to a fixed position of a pump body part, reducing part deformation, and solving the problem that the muffler chambers are overlapped so that the upper and lower muffler screw holes are also overlapped, so that the upper and lower screws simultaneously apply screw force to a fixed position of a pump body part, thereby increasing part deformation.

[0070] In some embodiments,

[0071] In the axial projection plane of the pump body structure, an angle α is formed between the first center line 5 and the second center line 6, and α≥10°.

[0072] The present invention further satisfies α≥10° by setting the included angle α between the center line of the offset upper muffler chamber and the center line of the lower muffler chamber, thereby further reducing the superposition effect of noise radiation generated by the upper and lower muffler chambers simultaneously in a fixed angle and direction, improving the noise reduction effect, and further solving the problem of parts deformation caused by the upper and lower screws facing the same fixed position.

[0073] In some embodiments,

[0074] The compressor pump body structure has a central axis. In the axial projection plane of the pump body structure, the projection of the central axis is the center of the pump body structure. The first center line 5 passes through the center of the pump body structure, and the second center line 6 passes through the center of the pump body structure.

[0075] This is the preferred structural form of the upper and lower silencer chambers of the upper and lower silencers of the present invention, that is, the center lines of the upper and lower silencer chambers preferably pass through the center of the pump body structure in the axial projection plane, which can form a symmetrical uniform structure of the silencer chambers in the circumferential direction, improve the uniformity of the structure, and further improve the effect of silencing and noise reduction.

[0076] In some embodiments,

[0077] The first muffler chamber 3 is communicated with the second muffler chamber 4 via a vent hole 7 .

[0078] The present invention can form a series-connected sound-absorbing chamber structure with the first and second sound-absorbing chambers by setting the vent holes, so that the gas silenced by the first or second sound-absorbing chamber can be further silenced by the second or first sound-absorbing chamber, thereby improving the sound-absorbing effect.

[0079] The function of the vent hole is to allow the gas discharged from the exhaust hole of the lower flange to enter the lower muffler, then enter the upper muffler through the vent hole set in the pump body, and then be discharged from the upper muffler.

[0080] In some embodiments,

[0081] In the projection plane of the axial end face of the first muffler 1, the vent hole 7 has a first vent hole center 8, and the line between the center of the first muffler 1 and the first vent hole center 8 does not coincide with the first center line 5, and there is a misalignment;

[0082] In the projection plane of the axial end face of the second muffler 2, the vent hole 7 has a second vent hole center 9, and the line between the center of the second muffler 2 and the second vent hole center 9 does not coincide with the second center line 6, and there is a misalignment.

[0083] The present invention sets the ventilation center of the vent hole to be offset with the line connecting the center of the muffler and the center line of the muffler chamber, so that the gas flow in the lower muffler chamber and the upper muffler chamber can be more regular and smoother, thereby reducing gas flow losses and reducing compressor power consumption.

[0084] In some embodiments,

[0085] The angle between the line between the center of the first muffler 1 and the center of the first vent hole 8 and the first center line 5 is an offset angle β, and β≥6°; the angle between the line between the center of the second muffler 2 and the center of the second vent hole 9 and the second center line 6 is also an offset angle β, and β≥6°.

[0086] The present invention further sets the offset angle β between the line between the center of the vent hole and the center of the muffler and the center line of the muffler chamber to β≥6°, which can further make the gas flow in the lower muffler chamber and the upper muffler chamber more regular and smoother, thereby reducing gas flow losses and reducing compressor power consumption.

[0087] In some embodiments,

[0088] The vent hole 7 is a straight channel, and its extending direction is parallel to the axis of the pump body structure.

[0089] This is the preferred structural form of the vent hole of the present invention, that is, it is preferably a straight channel structure extending parallel to the axis of the pump body structure, which can be easily processed when the upper and lower muffler chambers are connected.

[0090] In some embodiments,

[0091] The vent hole 7 includes a first channel section 11, a second channel section 12 and an intermediate connecting section 10, one end of the first channel section 11 is connected to the first muffler chamber 3, one end of the second channel section 12 is connected to the second muffler chamber 4, the first channel section 11 and the second channel section 12 are connected through the intermediate connecting section 10, and the axis of the first channel section 11 and the axis of the second channel section 12 are not located on the same straight line, but are misaligned.

[0092] like Figure 12-13 As shown, this is the preferred structural form of the vent holes of the present invention. The vent holes are divided into an upper, middle and lower three-section structure to form a multi-section vent section structure. The upper and lower vent holes can be staggered when the upper and lower silencer chambers are connected. The upper vent holes are connected to the upper silencer chamber, and the lower vent holes are connected to the lower silencer chamber. The cross-sectional area of ​​the middle vent holes is larger than that of the upper vent holes and the lower vent holes, and the upper vent holes and the lower vent holes are connected to ensure good connectivity between the staggered upper and lower silencer chambers.

[0093] The segmented vent holes can be staggered between the vent holes in the upper muffler chamber and the vent holes in the lower muffler chamber, so that the vent holes in the upper muffler chamber and the vent holes in the lower muffler chamber are well connected with the upper muffler chamber and the lower muffler chamber respectively, making the airflow smoother.

[0094] The pump body assembly of the present invention has a vent hole 7 connecting the upper muffler chamber of the upper muffler and the lower muffler chamber of the lower muffler, and is characterized in that the vent hole in the upper muffler chamber is staggered with the vent hole in the lower muffler chamber. The staggered vent holes can make the vent hole in the upper muffler chamber and the vent hole in the lower muffler chamber well connected with the upper muffler chamber and the lower muffler chamber respectively, so that the airflow is smoother. In particular, when the muffler chamber is small and the flow hole is large, the vent hole can be completely located in the muffler chamber to avoid the flow hole being covered. Figure 12-14 shown.

[0095] In some embodiments,

[0096] The first channel section 11 extends along the axial direction of the pump body structure, and the second channel section 12 extends along the axial direction of the pump body structure.

[0097] This is the preferred structural form of the upper and lower three-stage multi-stage vent structure of the present invention, which can ensure convenient processing and air guiding function of the first and second channel sections, and complete the communication between the upper and lower offset muffler chambers.

[0098] In some embodiments,

[0099] The vent hole 7 includes an inclined channel section 13, one end of which is connected to the first muffler chamber 3, and the other end is connected to the second muffler chamber 4. The axis of the inclined channel section 13 is not parallel to the axis of the pump body structure, and there is an inclined angle.

[0100] like Fig.14 This is the third structural form of the vent hole of the present invention, that is, the structure of the inclined channel section is adopted, which can effectively complete the communication between the upper and lower offset muffler chambers.

[0101] The pump body structure of the present invention has a vent hole, which connects the upper muffler chamber of the upper muffler and the lower muffler chamber of the lower muffler, and is characterized in that the vent hole is an inclined hole. The inclined hole can realize the staggered arrangement of the vent hole in the upper muffler chamber and the vent hole in the lower muffler chamber, so that the vent hole in the upper muffler chamber and the vent hole in the lower muffler chamber can be well connected with the upper muffler chamber and the lower muffler chamber respectively, and compared with the segmented vent hole, the inclined vent hole can make the gas pass through the vent hole better, so as to realize the connection between the lower muffler chamber and the upper muffler chamber.

[0102] In some embodiments,

[0103] A plurality of first silencer chambers 3 are also provided on the first silencer 1, and the plurality of first silencer chambers 3 are arranged at intervals along the circumferential direction. A plurality of second silencer chambers 4 are also provided on the second silencer 2, and the plurality of second silencer chambers 4 are arranged at intervals along the circumferential direction, and the first silencer chambers 3 are connected to the second silencer chambers 4 in a one-to-one correspondence.

[0104] The present invention can increase the silencing volume and improve the silencing effect through the multiple first silencing chambers on the first silencer, and the multiple second silencing chambers on the second silencer can increase the silencing volume and improve the silencing effect. The multiple first silencing chambers and the multiple second silencing chambers are connected one by one, which can further improve the silencing effect on the gas.

[0105] In some embodiments,

[0106] It also includes a connecting hole 14, one end of which is connected to the second muffler chamber 4, and the other end is connected to the outside of the second muffler chamber 4 (preferably, the other end of the connecting hole is connected to the first muffler and is located outside the first muffler chamber to discharge the gas in the second muffler chamber); and / or,

[0107] The first muffler 1 and the second muffler 2 are arranged up and down, and the first muffler 1 is located above the second muffler 2 .

[0108] The pump body structure of the present invention also has a connecting hole 14, which can directly lead part of the gas in the muffler chamber of the lower muffler to the outside of the pump body.

[0109] like Figure 8-11 As shown, the function of the connecting hole 14 is that part of the gas in the lower muffler is directly discharged to the outside of the upper muffler through the connecting hole, and the gas passing through the connecting hole no longer passes through the upper muffler.

[0110] The first muffler of the present invention is preferably an upper muffler located above the cylinder, and the second muffler is preferably a lower muffler located below the cylinder.

[0111] In some embodiments,

[0112] It comprises a single cylinder, the first muffler 1 is located on one axial side of the single cylinder, and the second muffler 2 is located on the other axial side of the single cylinder; or,

[0113] It comprises more than two cylinders, which constitute a compression unit. The first muffler 1 is located on one axial side of the compression unit, and the second muffler 2 is located on the other axial side of the compression unit.

[0114] The first preferred structural form of the present invention is a single-cylinder compressor. The pump body assembly adopts the above structure. The single-cylinder compressor is a double exhaust structure. The upper flange and the flange are both provided with exhaust holes. The gas discharged from the exhaust hole of the upper flange enters the upper muffler and is then discharged from the upper muffler. The gas discharged from the exhaust hole of the lower flange enters the lower muffler. It is characterized in that the silencer chamber of the upper muffler and the silencer chamber of the lower muffler are staggered, which effectively avoids the situation where the compressor generates excessive noise in a fixed direction, and solves the problem that the upper and lower silencer chambers of the existing compressor simultaneously generate noise radiation in a fixed angle and fixed direction, and the noise radiation of the two is superimposed, resulting in the problem of the compressor generating excessive noise in a fixed direction.

[0115] The second preferred structural form of the present invention is a twin-cylinder compressor, in which the upper cylinder discharges gas through the exhaust hole set on the upper flange, enters the upper muffler, and then discharges from the upper muffler, and the lower cylinder discharges gas through the exhaust hole set on the lower flange, enters the lower muffler, and then enters the upper muffler from the lower muffler through the vent hole set on the pump body, and then discharges from the upper muffler. Its characteristic is that the muffler chamber of the upper muffler and the muffler chamber of the lower muffler are staggered, which effectively avoids the situation where the compressor generates excessive noise in a certain fixed direction, and solves the problem that the upper and lower muffler chambers of the existing compressor simultaneously generate noise radiation in a certain fixed angle and fixed direction, and the noise radiation of the two is superimposed, resulting in the compressor generating excessive noise in a certain fixed direction.

[0116] The present invention also provides a compressor, which comprises the above compressor pump body structure.

[0117] The present invention can achieve the staggered setting of the upper and lower muffler locking screws by staggering the muffler chamber of the compressor pump body, thereby preventing the upper and lower screws from simultaneously applying screw force to a certain fixed position of a pump body part, thereby reducing the deformation of the part. On the other hand, the staggered setting of the muffler chamber can prevent the upper and lower muffler chambers from simultaneously generating noise radiation in a certain fixed angle and direction, thereby reducing the superposition effect of the two and preventing the compressor from generating excessive noise in a certain fixed direction.

[0118] The present invention can solve the following technical problems:

[0119] 1. The anechoic chambers of the upper and lower mufflers radiate noise at a fixed angle and direction at the same time. The superposition of the noise radiation of the two can easily cause the compressor to produce excessive noise in a fixed direction.

[0120] 2. The overlapping setting of the anechoic chamber causes the upper and lower muffler screw holes to also overlap, so that the upper and lower screws simultaneously apply screw force to a certain fixed position of a certain pump body part, increasing the problem of part deformation.

[0121] Beneficial effects:

[0122] 1. Reduce compressor noise.

[0123] 2. Reduce parts deformation.

[0124] The present invention also provides an air conditioner, which comprises the aforementioned compressor.

The above description is only a preferred embodiment of the present invention.
