Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioning equipment, and in particular to a compressor assembly and an air conditioner. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for air-conditioning noise. For example, the vibration of the compressor inside the air-conditioning outdoor unit causes the resonance noise generated by the pipes connected to it and the external chassis shell, which affects the user experience.

[0003] In the related art, the compressor is installed in the outer chassis shell through the machine feet. However, considering that a liquid reservoir is provided on one side of the compressor, this causes the feet to bear uneven impact force when the compressor vibrates, which in turn causes the compressor to vibrate more, exacerbating the resonance noise of the pipelines connected to the compressor and the outer chassis shell. Utility Model Content

[0004] To overcome the problems existing in the related art, the present disclosure provides a compressor assembly and an air conditioner.

[0005] According to a first aspect of an embodiment of the present disclosure, there is provided a compressor assembly, comprising:

[0006] A compressor cylinder body, wherein the compressor cylinder body is connected to a plurality of machine feet;

[0007] a liquid accumulator connected to one side of the compressor cylinder;

[0008] Wherein, the extension length of at least one of the machine feet close to the liquid reservoir is configured to be greater than the extension lengths of several of the machine feet away from the liquid reservoir.

[0009] Optionally, the geometric centers of the fixed restraint points of the plurality of machine feet and the center of gravity of the assembly consisting of the compressor cylinder and the liquid reservoir are distributed along the same vertical straight line.

[0010] Optionally, a plurality of the machine feet are arranged at equal angles along the circumferential direction at the bottom of the compressor cylinder.

[0011] Optionally, the number of the machine feet is three, including two first machine feet and one second machine foot, the first machine feet are arranged on the side of the compressor cylinder away from the liquid reservoir, and the second machine feet are arranged on the side of the compressor cylinder close to the liquid reservoir.

[0012] Optionally, the second machine foot is located below the center of gravity of the liquid reservoir.

[0013] Optionally, a horizontal straight-line distance between a fixed restraining point of the second machine foot and the center of gravity of the compressor cylinder is greater than or equal to a horizontal straight-line distance between the center of gravity of the liquid reservoir and the center of gravity of the compressor cylinder.

[0014] Optionally, flange structures are provided on both sides of the machine foot along the extension direction, and the flange structures are bent in a direction away from the compressor cylinder body.

[0015] Optionally, the size of the flange structure at a position close to the compressor cylinder is larger than that at other positions.

[0016] Optionally, the compressor assembly further includes an elastic vibration damper detachably mounted on the bottom of the machine foot.

[0017] According to a second aspect of an embodiment of the present disclosure, there is provided an air conditioner comprising any one of the above-mentioned compressor assemblies.

[0018] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: the extension length of at least one machine foot on the side of the compressor assembly provided by the present disclosure close to the liquid reservoir is configured to be greater than the extension length of several machine feet on the side away from the liquid reservoir. Different from the design scheme of multiple machine feet of equal length in the related art, the compressor assembly provided by the present disclosure adopts an unequal length machine foot design, specifically, the machine foot close to the liquid reservoir is lengthened, which makes the distance from the support point of the machine foot to the center of gravity of the compressor cylinder longer, which is equivalent to lengthening the force arm, reducing the reaction force generated at the machine foot support point, avoiding the impact force generated by the vibration of the compressor from being too concentrated on the machine foot on the side of the liquid reservoir, so that the impact force borne by the multiple machine feet is more uniform, which is conducive to reducing the vibration of the compressor and reducing the resonance noise generated by the pipeline connected to the compressor and the outer chassis shell.

[0019] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0027] like Figures 1 to 3 As shown, an exemplary embodiment of the present disclosure provides a compressor assembly, which is suitable for a variety of equipment that has vibration reduction requirements for the compressor, and the present disclosure does not limit this. For example, it can be applied to an air-conditioning outdoor unit. Specifically, the compressor assembly provided by the present disclosure includes a compressor cylinder 1 and a liquid reservoir 2. The compressor is accommodated in the compressor cylinder 1. The compressor cylinder 1 is connected to a plurality of machine feet 3, which are used to support the compressor cylinder 1 and can fix the compressor cylinder 1 in the outer chassis shell. The machine feet 3 can be provided at the bottom or side of the compressor cylinder 1. In some embodiments, the machine feet 3 can be constructed in a plate shape, and the heights of the plurality of machine feet 3 are equal, so that the compressor cylinder 1 does not tilt after installation. In addition, the top of the compressor cylinder 1 can also be provided with an output pipe 7 for transporting refrigerant to the outside and a connection terminal 8 for electrical connection.

[0028] The accumulator 2 is connected to one side of the compressor cylinder 1. The accumulator 2 is connected to the compressor cylinder 1 through the inlet pipe 5. The refrigerant that has not completely evaporated or gasified in the evaporator enters the accumulator 2. The liquid refrigerant is separated due to gravity and inertia and accumulates at the bottom of the accumulator 2. The separated gaseous refrigerant is transported to the compressor cylinder 1 through the inlet pipe 5, while the separated liquid refrigerant returns to the system and continues to participate in the refrigeration cycle.

[0029] Different from the aforementioned compressor cylinder 1 which is supported and fixed by the machine foot 3, the accumulator 2 is usually connected to the compressor cylinder 1, that is, it can be considered that the accumulator 2 is supported and fixed by means of the compressor cylinder 1. Figure 1 and Figure 2In the illustrated embodiment, the accumulator 2 is detachably connected to the compressor cylinder 1 using a fixing member 6, which may be, for example, a clamp. The compressor cylinder 1 and the accumulator 2 are typically cylindrical, with the center of gravity of the compressor cylinder 1 located on an axis passing through the center of the circle. However, the placement of the accumulator 2 on the side of the compressor cylinder 1 will cause the center of gravity of the assembly consisting of the compressor cylinder 1 and the accumulator 2 to be offset, i.e., the center of gravity of the assembly is offset toward the accumulator 2.

[0030] In the prior art, the lengths of multiple machine feet 3 are all the same, and the resulting problem is that when the compressor vibrates, the machine feet 3 on the side of the bottom of the compressor cylinder 1 close to the liquid reservoir 2 are subjected to a greater impact force, while the impact force on several machine feet 3 on the other side, that is, away from the liquid reservoir 2, is relatively small, resulting in uneven impact force on the machine feet 3 on both sides of the compressor cylinder 1, which causes the compressor to vibrate more, and then causes resonance noise in the pipelines connected to the compressor cylinder 1 and the outer chassis shell.

[0031] In order to solve the above technical problems, the present invention configures the extension length of at least one machine foot 3 close to the liquid reservoir 2 to be greater than the extension length of the machine foot 3 away from the liquid reservoir 2. Figure 2 and Figure 3 For example, the side close to the liquid reservoir 2 here refers to the right side of the figure, and the side away from the liquid reservoir 2 refers to the left side of the figure. Different from the scheme of designing multiple machine feet 3 of equal length in the related art, the present disclosure actually provides a design scheme of machine feet 3 of unequal length, specifically, lengthening the machine feet 3 on the side close to the liquid reservoir 2. This makes the distance between the support point of the machine foot 3 and the center of gravity of the compressor cylinder 1 longer, which is equivalent to lengthening the force arm, reducing the reaction force generated at the support point of the machine foot 3, and avoiding the impact force generated by the vibration of the compressor from being too concentrated on the machine foot 3 on the side of the liquid reservoir 2, so that the impact force borne by multiple machine feet 3 is more uniform, which is beneficial to reduce the vibration of the compressor and reduce the resonance noise generated by the pipes and the external chassis shell connected to the compressor.

[0032] In addition, by configuring the extension length of at least one machine foot 3 on the side close to the liquid reservoir 2 to be greater than the extension length of the machine foot 3 on the side away from the liquid reservoir 2, it is also possible to avoid, for example, the tilting of the compressor due to uneven weight distribution of the compressor when the air-conditioning outdoor unit falls during transportation, thereby avoiding collision between the compressor and structural parts, thereby reducing pipeline deformation.

[0033] The geometric centers of the fixed restraint points of the multiple machine feet 3 can be distributed along the same vertical straight line as the center of gravity of the combination consisting of the compressor cylinder 1 and the liquid reservoir 2. As mentioned above, after the liquid reservoir 2 is installed on the compressor cylinder 1 through the fixing member 6, the two can be regarded as a new combination, and the center of gravity of the combination is offset toward the direction of the liquid reservoir 2 relative to the center of gravity W1 of the compressor cylinder 1. The compressor assembly provided by the present invention lengthens the machine foot 3 on the side close to the liquid reservoir 2, which makes the geometric centers of the fixed restraint points of the multiple machine feet 3 also offset toward the direction of the liquid reservoir 2, as shown in FIG. Figure 3 As shown, when the geometric center W2 of the fixed constraint points of multiple machine feet 3 and the center of gravity of the combination composed of the compressor cylinder 1 and the liquid reservoir 2 are distributed along the same vertical straight line, it can provide more stable support, further reduce the vibration of the compressor and reduce the resonance noise generated by the pipes connected to the compressor and the external chassis shell.

[0034] It should be noted that the fixed constraint point of the machine foot 3 is the point where the machine foot 3 is fixed to the external chassis shell. For example, the machine foot 3 is provided with a mounting hole, which can be directly connected to the external chassis shell, or connected to the external chassis shell through the elastic vibration damping member 4 to be introduced below, wherein the center of the mounting hole is the fixed constraint point.

[0035] In some embodiments, reference may be made to Figure 2 and Figure 3 The machine foot 3 includes a first machine foot 31 provided on the side of the compressor cylinder 1 away from the liquid reservoir 2, and a second machine foot 32 provided on the side of the compressor cylinder 1 close to the liquid reservoir 2. The machine feet 3 are both connected to the compressor cylinder 1, and the first machine foot 31 and the second machine foot 32 extend in the directions close to and away from the sides of the liquid reservoir 2, respectively, which helps to further improve the support stability of the machine foot 3.

[0036] The present disclosure does not limit the number of the first machine feet 31 and the second machine feet 32. For example, one first machine foot 31 and one second machine foot 32 may be provided on the side of the compressor cylinder 1 close to the liquid reservoir 2 and on the side away from the liquid reservoir 2; or two first machine feet 31 and two second machine feet 32 may be provided on the side of the compressor cylinder 1 close to the liquid reservoir 2 and on the side away from the liquid reservoir 2; or Figure 2 and Figure 3 As shown, one second machine foot 32 is provided on the side close to the liquid reservoir 2 and two first machine feet 31 are provided on the side away from the liquid reservoir 2 .

[0037] Multiple machine feet 3 can be configured to be arranged at equal angles along the circumference at the bottom of the compressor cylinder 1. This equidistant arrangement of machine feet 3 is conducive to further improving the stability of the support of the machine feet 3. For example, Figure 2 and Figure 3The illustrated embodiment has three machine feet 3, including two first machine feet 31 and one second machine foot 32. These three machine feet 3 are arranged at equal angles around the circumference, that is, one machine foot 3 is provided every 120 degrees. This arrangement enables the three machine feet 3 to form a triangular support for the compressor cylinder body 1. This triangular support provides the most stable support while utilizing a smaller number of machine feet 3, thereby reducing the weight of the entire machine.

[0038] In some embodiments, as Figure 2 and Figure 3 As shown, the second machine foot 32 is located below the center of gravity of the liquid reservoir 2. At this time, the extended force arm formed by the second machine foot 32 corresponds to the position of the liquid reservoir 2, further enhancing the effect of the second machine foot 32 in reducing the reaction force of the support point. Figure 1 , the horizontal straight-line distance L2 between the fixed restraint point of the second machine foot 32 and the center of gravity of the compressor cylinder body 1 is greater than or equal to the horizontal straight-line distance L1 between the center of gravity of the liquid accumulator 2 and the center of gravity of the compressor cylinder body 1. In other words, the horizontal straight-line distance L that the fixed restraint point of the second machine foot 32 extends laterally outward beyond the center of gravity of the liquid accumulator 2, where L ≥ 0. The specific value of L can be determined based on actual needs. For example, the value of L can be configured so that the geometric center of the fixed restraint points of the multiple machine feet 3 coincides with the center of gravity of the assembly consisting of the compressor cylinder body 1 and the liquid accumulator 2 in the vertical direction.

[0039] Considering that the machine foot 3 is a supporting member, it is necessary to ensure the structural strength of the machine foot 3. Figure 1 As shown, in some embodiments, flange structures 33 are provided on both sides of the machine foot 3 along the extension direction, and the flange structures 33 are bent in the direction away from the compressor cylinder body 1, that is, bent in the direction of the lower plate surface of the machine foot 3. The flange structure 33 is similar to the ribs with structural reinforcement formed on both sides of the extension direction of the machine foot 3, which is beneficial to improving the bending strength of the machine foot 3. By bending the flange structure 33 in the direction away from the compressor cylinder body 1, it is possible to avoid the compressor cylinder body 1 installed on the upper plate surface of the machine foot 3. Taking into account that the machine foot 3 is subjected to a greater bending moment at a position close to the compressor cylinder body 1, the flange structure 33 can further have a wider size at a position close to the compressor cylinder body 1 than at other positions, so that it has greater bending strength at a position with a larger bending moment.

[0040] In addition, if Figure 1As shown, the compressor assembly of the present disclosure may further include an elastic damper 4 mounted on the bottom of the machine foot 3. The elastic damper 4 may be fixed to the machine foot 3 or configured to be detachably connected to the machine foot 3. The elastic damper 4 may be, for example, a vibration-damping pad made of a rubber material, which is disposed between the machine foot 3 and the inner bottom wall of the outer chassis shell to isolate vibrations. The elastic damper 4 is provided with a hole for threaded fasteners to pass through. During installation, the threaded fasteners pass through the mounting holes on the machine foot 3 and the elastic damper 4 in sequence.

[0041] According to a second aspect of an embodiment of the present disclosure, an air conditioner is also provided, comprising any one of the compressor assemblies described above and having all of its beneficial effects, which will not be described in detail here.

[0042] In the foregoing detailed description, reference is made to the accompanying drawings, which illustrate, by way of illustration, specific aspects of the present disclosure in which it may be practiced.

Since the components of the described devices may be positioned in a plurality of different orientations, the directional terms may be used for illustrative purposes rather than restrictive. It should be understood that other aspects may be utilized and structural or logical changes may be made without departing from the concepts of the present disclosure. Therefore, the following detailed description should not be taken in a limiting sense.

However, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may alternatively have a specific meaning: the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, e.g., in direct contact with the surface.

[0046] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or sections, these components, parts, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one component, part, region, layer or section from another component, part, region, layer or section. Therefore, without departing from the teachings of each example, the first component, part, region, layer or section mentioned in the examples described herein may also be referred to as the second component, part, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

Such spatially relative terms are 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, an element described as being "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" encompasses both above and below orientations, depending on the spatial orientation of the device. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0048] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies to A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies to A; X applies to B; or X applies to both A and B, then "X applies to A or B" satisfies any of the aforementioned instances. Furthermore, the articles "a" and "an," as used in this application and the appended claims, are generally understood to mean "one or more," unless otherwise specified or clear from the context to refer to the singular form.
