The present invention provides a reciprocating compressor.
In the embodiment of the present invention, as shown in fig. 1 and 2, the reciprocating compressor 10 includes a lower housing 200, a motor, a cylinder 300, and a motor wiring part 400.
The lower housing 200 has a flange face 202, a first end 204 and a second end 206.
In the present embodiment, the lower housing 200 is a hollow structure with one open end and one closed end, and the lower housing 200 has an accommodating cavity 200a. The closed end of the lower casing 200 is located below the open end of the lower casing 200, that is, the closed end of the lower casing 200 is located at the lower part of the lower casing 200, and the open end of the lower casing 200 is located at the upper part of the lower casing 200.
In the present embodiment, the flange face 202 is located at an upper portion of the lower case 200, that is, at an open end of the lower case 200. The flange face 202 is a closed ring structure. The flange face 202 has a certain width in the radial direction, and the width of the flange face 202 in the radial direction is the same as the thickness of the lower case 200.
In the present embodiment, the flange face 202 has a first axis 202a and a second axis 202b. The first axis 202a and the second axis 202b are orthogonal, i.e., the first axis 202a and the second axis 202b are disposed perpendicularly. The number of the first end portions 204 is two, and the two first end portions 204 are arranged at intervals along the first axis 202 a. The number of the second ends 206 is two, and the two second ends 206 are spaced along the second axis 202b.
The motor, the cylinder 300, and the motor wiring part 400 are all provided on the lower case 200, that is, the lower case 200 is a carrier of the motor, the cylinder 300, and the motor wiring part 400. Specifically, in the present embodiment, the motor is located in the accommodating cavity 200a of the lower housing 200, that is, the motor is accommodated in the accommodating cavity 200a. And at least portions of the cylinder 300 and the motor wiring portion 400 are located above the motor.
The motor can control the operation of the cylinder 300. Specifically, in the present embodiment, during the operation of the motor-controlled cylinder 300, the motor may drive the piston in the cylinder 300 to move. The motor wiring part 400 is electrically connected to the motor. When the reciprocating compressor 10 is operated, the motor wiring part 400 is electrically connected to an external power source so that the external power source can supply power to the motor, and the motor can drive the piston in the cylinder 300 to move.
In the present embodiment, the cylinder 300 is located at one of the first end 204 and the second end 206, and the motor wiring portion 400 is located at the other of the first end 204 and the second end 206. That is, in the present embodiment, when the cylinder 300 is located at one of the two first end portions 204, the motor wiring portion 400 is located at one of the two second end portions 206, and when the cylinder 300 is located at one of the two second end portions 206, the motor wiring portion 400 is located at one of the two first end portions 204.
In the related art, either the cylinder 300 is located at one of the two first end portions 204, and the motor wiring portion 400 is located at the other of the two first end portions 204, which may result in a larger length of the first shaft 202a, i.e., a larger difference between the length of the first shaft 202a and the length of the second shaft 202b, resulting in the flange surface 202 deviating from the circular shape, i.e., adversely affecting the circular shape of the flange surface 202 (as shown in fig. 4); or the cylinder 300 is located at one of the two second end portions 206 and the motor connecting portion 400 is located at the other of the two second end portions 206, which may result in a larger length of the second shaft 202b, i.e., may result in a larger difference between the length of the first shaft 202a and the length of the second shaft 202b, which may result in the flange surface 202 deviating from the circular shape, i.e., may be detrimental to the circular shape of the flange surface 202 (as shown in fig. 4).
In the reciprocating compressor 10, as shown in fig. 1 to 3, the cylinder 300 is located at one of the first end 204 and the second end 206, and the motor wiring portion 400 is located at the other of the first end 204 and the second end 206, so that the difference between the length of the first shaft 202a and the length of the second shaft 202b is smaller, and thus the flange face 202 is controlled to be rounded, the lower shell 200 is made to be spherical, and the lower shell 200 is made to be more approximately spherical, so that the shell of the reciprocating compressor 10 including the lower shell 200 and the upper shell is made to be more approximately spherical, and the shell of the reciprocating compressor 10 which is more approximately spherical is made to be more symmetric in structure, which is beneficial to reducing noise radiation during the operation of the reciprocating compressor 10. And the more spherical shape of the housing of the reciprocating compressor 10 has a smaller space, which is more beneficial to the miniaturization design of the reciprocating compressor 10 and saves space. Therefore, the reciprocating compressor 10 can reduce the volume of the compressor and save space while improving the noise of the compressor.
In the present embodiment, the axis 300a of the cylinder hole of the cylinder 300 is perpendicular to the center line 400a of the terminal of the motor terminal portion 400. In this way, it is more beneficial to control the rounding of the flange surface 202, i.e. to control the rounding of the lower housing 200. In the present embodiment, the fact that the axis 300a of the cylinder hole of the cylinder 300 is perpendicular to the center line 400a of the terminal of the motor terminal portion 400 means that the axis 300a of the cylinder hole of the cylinder 300 is substantially perpendicular to the center line 400a of the terminal of the motor terminal portion 400, and is not absolutely perpendicular, and there may be an error. Specifically, in the present embodiment, when the axis 300a of the cylinder hole of the cylinder 300 makes an angle of 80 ° to 100 ° with the center line 400a of the terminal of the motor terminal portion 400, it can be considered that the axis 300a of the cylinder hole of the cylinder 300 is perpendicular to the center line 400a of the terminal of the motor terminal portion 400.
It is understood that, in other embodiments, the axis 300a of the cylinder hole of the cylinder 300 and the center line 400a of the terminal of the motor terminal portion 400 may not be perpendicular. That is, in the present embodiment, the first end portion 204 and the second end portion 206 have a certain area range, which is beneficial for controlling the rounding of the flange surface 202 when the cylinder 300 is in the area range of one of the first end portion 204 and the second end portion 206, and the motor wiring portion 400 is in the area range of the other of the first end portion 204 and the second end portion 206. The axis 300a of the cylinder hole of the cylinder 300 is perpendicular to the central line 400a of the wiring terminal of the motor wiring part 400, so that the flange face 202 can be controlled to be circular.
In some embodiments, as shown in fig. 1, the cylinder 300 is located at the first end 204, with the axis 300a of the cylinder bore of the cylinder 300 parallel to the first shaft 202 a. The motor wire connection portion 400 is located at the second end portion 206, and a center line 400a of a wire connection terminal of the motor wire connection portion 400 is parallel to the second shaft 202b. In this way, it is more advantageous to control the rounding of the flange face 202, i.e. to control the sphericization of the lower shell 200. It is understood that in other embodiments, the cylinder 300 may be located at the first end 204 with the axis 300a of the cylinder bore of the cylinder 300 being non-parallel to the first shaft 202a and/or the motor connection portion 400 may be located at the second end 206 with the centerline 400a of the connection terminal of the motor connection portion 400 being non-parallel to the second shaft 202b.
Specifically, in the present embodiment, the cylinder 300 is located at the first end 204, and the axis 300a of the cylinder bore of the cylinder 300 is collinear with the first shaft 202a, i.e., the axis 300a of the cylinder bore of the cylinder 300 is collinear with the first shaft 202 a. The motor connecting portion 400 is located at the second end portion 206, and the center line 400a of the connecting terminal of the motor connecting portion 400 is collinear with the second axis 202b, that is, the motor connecting portion 400 is located at the second end portion 206, and the center line 400a of the connecting terminal of the motor connecting portion 400 is collinear with the second axis 202b. In this way, it is more advantageous to control the rounding of the flange face 202, i.e. to control the sphericization of the lower shell 200. It is understood that in other embodiments, the cylinder 300 may be located at the first end 204 with the axis 300a of the cylinder bore of the cylinder 300 not collinear with the first shaft 202a and/or the motor terminal portion 400 may be located at the second end 206 with the centerline 400a of the terminal of the motor terminal portion 400 not collinear with the second shaft 202b.
In some embodiments, as shown in fig. 2, the cylinder 300 is located at the second end 206, with the axis 300a of the bore of the cylinder 300 parallel to the second axis 202b. The motor wiring portion 400 is located at the first end portion 204, and a center line 400a of a wiring terminal of the motor wiring portion 400 is parallel to the first shaft 202 a. In this way, it is more advantageous to control the rounding of the flange face 202, i.e. to control the sphericization of the lower shell 200. It is understood that in other embodiments, the cylinder 300 may be located at the second end 206 with the axis 300a of the cylinder bore of the cylinder 300 being non-parallel to the second axis 202b and/or the motor connection portion 400 may be located at the first end 204 with the centerline 400a of the connection terminal of the motor connection portion 400 being non-parallel to the first axis 202 a.
Specifically, in the present embodiment, the cylinder 300 is located at the second end 206, and the axis 300a of the cylinder bore of the cylinder 300 is collinear with the second shaft 202b, that is, the cylinder 300 is located at the second end 206, and the axis 300a of the cylinder bore of the cylinder 300 is collinear with the second shaft 202b. The motor wire connection portion 400 is located at the first end portion 204, and a center line 400a of a wire connection terminal of the motor wire connection portion 400 is collinear with the first axis 202a, that is, the motor wire connection portion 400 is located at the first end portion 204, and the center line 400a of the wire connection terminal of the motor wire connection portion 400 is collinear with the first axis 202 a. In this way, it is more advantageous to control the rounding of the flange face 202, i.e. to control the sphericization of the lower shell 200. It is understood that in other embodiments, the cylinder 300 may be located at the second end 206 with the axis 300a of the cylinder bore of the cylinder 300 not collinear with the second shaft 202b and/or the motor connection portion 400 may be located at the first end 204 with the centerline 400a of the terminal of the motor connection portion 400 not collinear with the first shaft 202 a.
In the present embodiment, the connection terminal of the motor connection part 400 is similar to a plug having three legs, and at this time, the center line 400a of the connection terminal of the motor connection part 400 is the center line 400a of a figure defined by the three legs. In other embodiments, when the connection terminal of the motor connection part 400 is similar to a plug having two legs, the center line 400a of the connection terminal of the motor connection part 400 is the center line of a figure defined by the two legs.
In the present embodiment, the ratio of the length of the first shaft 202a to the length of the second shaft 202b is 1-1.2. Wherein the ratio of the length of the first shaft 202a to the length of the second shaft 202b may be 1.00, 1.01, 1.02, 1.03, 1.04, 1.05, 1.06, 1.07, 1.08, 1.09, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, or 1.20. When the ratio of the length of the first shaft 202a to the length of the second shaft 202b is 1 to 1.2, the flange face 202 is nearly circular, so that the lower shell 200 can be made more approximately spherical, and thus the shell of the reciprocating compressor 10 including the lower shell 200 and the upper shell can be made more approximately spherical.
Specifically, in the present embodiment, the length of the first shaft 202a is greater than the length of the second shaft 202b. When the length of the first shaft 202a is equal to the length of the second shaft 202b, that is, when the ratio of the length of the first shaft 202a to the length of the second shaft 202b is 1.00, the flange surface 202 may be considered as being circular, which is very beneficial to reducing noise radiation during operation of the reciprocating compressor 10, and is also very beneficial to miniaturizing the design of the reciprocating compressor 10, and saving space. But compared with the traditional technology, the change range is larger, and the influence on the arrangement of components such as a motor is larger. In order to reduce the influence on the arrangement of the components such as the motor, the length of the first shaft 202a is set to be greater than that of the second shaft 202b, that is, the length of the first shaft 202a is set to be different from that of the second shaft 202b.
More specifically, in the present embodiment, the ratio of the length of the first shaft 202a to the length of the second shaft 202b is 1.05-1.15. Thus, the influence on the arrangement of components such as a motor can be reduced, and the flange surface 202 can be close to a circular shape.
In the present embodiment, as illustrated in fig. 5, the reciprocating compressor 10 further includes an upper housing 500 and a flange. The upper case 500 is flange-coupled to the flange surface 202 of the lower case 200. It should be noted that in the present embodiment, the upper shell 500 is formed to be matched with the shape of the lower shell 200, so that the shell of the reciprocating compressor 10 including the lower shell 200 and the upper shell 500 is more approximately spherical, and the more approximately spherical shell of the reciprocating compressor 10 has a more symmetrical structure, which is beneficial to reduce noise radiation during the operation of the reciprocating compressor 10.
As shown in fig. 5, the present embodiment further provides a refrigerator, where the refrigerator includes the reciprocating compressor 10, and the specific structure of the reciprocating compressor 10 refers to the above embodiments, and since the refrigerator adopts all technical solutions of all the above embodiments, at least all beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here. It is understood that in other embodiments, the reciprocating compressor 10 is not limited to being applied to a refrigerator, but may be applied to a home appliance such as an air conditioner.
Specifically, in the present embodiment, as shown in fig. 5, the refrigerator 10 further includes a bottom plate 20 and a shock-absorbing foot pad 30. The vibration damping foot pad 30 connects the base plate 20 with the lower case 200 of the reciprocating compressor 10. When the reciprocating compressor 10 is operated, vibration is generated, and the vibration generated from the reciprocating compressor 10 can be effectively prevented from being transferred to the base plate 20 by connecting the base plate 20 and the reciprocating compressor 10 through the vibration-damping foot pads 30, so that the refrigerator 10 having relatively small vibration noise can be obtained.
More specifically, in the present embodiment, the outer wall of the lower case 200 is provided with a bottom corner 210. The vibration damping foot pad 30 connects the base plate 20 with the bottom corner 210 of the reciprocating compressor 10. More specifically, in the present embodiment, the reciprocating compressor 10 has two bottom corners 210, and the two bottom corners 210 are located at opposite ends of the bottom of the lower housing 200, and in this case, the two bottom corners 210 may be considered to be spaced apart in the first direction. Each base corner 210 is connected to the base plate 20 by at least one shock absorbing foot pad 30. Specifically, in the present embodiment, each bottom corner 210 is connected to the bottom plate 20 through a plurality of damping feet 30, and the plurality of damping feet 30 are arranged at intervals along a second direction, which is perpendicular to the first direction. More specifically, in the present embodiment, each base corner 210 is connected to the base plate 20 by two shock absorbing foot pads 30.
In the present embodiment, the first direction is parallel to the first axis 202a, and the second direction is parallel to the second axis 202b. Thus, better vibration damping is achieved.
The above description is only an alternative embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, which are within the spirit of the present invention, are included in the scope of the present invention.
