[0053] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0054] The use of terms such as "first," "second," and similar words in the specific description does not indicate any order, quantity, or importance, but is merely used to distinguish different components. Furthermore, in the description of this utility model, terms such as "upper," "lower," etc., indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0055] It should be noted that the features of the embodiments of the present application and different embodiments can be combined with each other without conflict.

[0056] In the related art, as shown in Figure 1 、 Figure 2 and Figure 3 , the existing liquid reservoir support 100 basically adopts a fixing mode of a clamp and a connecting piece 150 in cooperation when fixing a larger diameter liquid reservoir 220, and the connecting piece 150 is usually a bolt. The liquid reservoir support 100 used in this fixing mode has longer support arms 140 on both sides, one of which is used to place a through hole 121 for fixing the connecting piece 150, and correspondingly, the through hole 121 is a bolt hole.

[0057] In some refrigeration equipment, because of the fixing position of the bottom plate of the refrigeration equipment and the limitation of the pipeline of the liquid reservoir 220, the bottom foot 230 of the compressor 200 is located below the support arm 140 on one side of the liquid reservoir support 100, and the bottom foot 230 of the compressor 200 is installed on the bottom plate of the refrigeration equipment by a mechanical hand.

[0058] However, the existing liquid reservoir support 100 has a longer support arm 140, which causes interference between the support arm 140 and the mechanical hand installing the bottom foot 230 when the bottom foot 230 of the compressor 200 is installed, making it inconvenient to install the bottom foot 230.

[0059] Therefore, in one aspect, as shown in Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , the embodiments of the present application provide a liquid reservoir support 100 applied to a compressor 200. The compressor 200 includes a body 210, a liquid reservoir 220, and a bottom foot 230 installed at the bottom of the body 210. The liquid reservoir support 100 includes a first positioning portion 110, a second positioning portion 130, a connecting portion 120, and a support arm 140.

[0060] Specifically, the support arm 140 has only one. The support arm 140 is connected to one end of the second positioning portion 130 away from the connecting portion 120. The end point of the support arm 140 of the liquid reservoir support 100 is A, and the end point of the second positioning portion 130 close to the bottom foot 230 is B. That is, the above-mentioned liquid reservoir support 100 has only one support arm 140 compared with the prior art, and the two end points of the liquid reservoir support 100 are end point A and end point B respectively.

[0061] Specifically, in the top view of the compressor 200, the body 210 has a first center O1, the liquid reservoir 220 has a second center O2, the bottom foot 230 has a circular mounting hole 231, and the mounting hole 231 has a third center O3.

[0062] Wherein, 65°≤∠AO2B≤120°, 25°≤∠O2O1O3≤50°, the distance between the end point B of the arm 140 and the third center O3 is greater than or equal to 9mm and less than or equal to 15mm, so as to form a space for the vertical installation of the mechanical hand.

[0063] It should be noted that the compressor 200 can include three feet 230, each of which is installed at the bottom of the body 210 and includes a mounting hole 231. The mounting hole 231 of the foot 230 closest to the bottom of the reservoir 220 has a third center O3, Figure 7 Only the foot 230 closest to the reservoir 220 is shown. The foot 230 is installed on the bottom plate of the refrigeration equipment through the mounting hole 231, and the fixing of the foot 230 and the bottom plate is achieved by tightening the bolt nut through the mechanical hand. The triangle formed by the centers of the mounting holes 231 of the three feet 230 is an equilateral triangle.

[0064] The above arrangement can form a space for the vertical downward extension of the mechanical hand and the installation of the foot by designing the structure and span parameters of the reservoir support 100 while maintaining the optimal balance of the relative positions of the body 210, the reservoir 220 and the foot 230, thereby avoiding the interference between the arm 140 and the mechanical hand installing the foot 230 when the foot 230 of the compressor 200 is installed. Therefore, the foot 230 of the compressor 200 can be closer to the lower end of the reservoir 220, so as to reuse the space below the reservoir 220, realize the miniaturization of the compressor 200, and avoid the interference between the foot 230 of the compressor 200 and other components of the refrigeration equipment.

[0065] It can be understood that the specific value of ∠AO2B can be any one of 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115° or 120°, and the present application does not limit it. The specific value of ∠O2O1O3 can be any one of 25°, 30°, 35°, 40°, 45° or 50°, and the present application does not limit it. The distance between the end point B of the arm 140 and the third center O3 can be any one of 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm, and the present application does not limit it.

[0066] Continuing to refer to Figure 6In some embodiments, the first positioning portion 110 abuts against the body 210, and a gap 111 is formed between the first positioning portion 110 and the outer wall of the body 210. The connecting portion 120 is provided with two connecting portions, which are connected to the two sides of the first positioning portion 110, respectively. At least one connecting portion 120 has a through hole 121 penetrating through the connecting portion 120. The second positioning portion 130 is provided with two second positioning portions, which are connected to the side of one connecting portion 120 away from the first positioning portion 110, respectively. The second positioning portion 130 abuts against the outer wall of the liquid accumulator 220. Specifically, the liquid accumulator support 100 is connected to the body 210 of the compressor 200 through the first positioning portion 110, and the side of the first positioning portion 110 close to the body 210 of the compressor 200 is arc-shaped to contact the outer wall of the body 210, thereby improving the connection strength. The gap 111 between the first positioning portion 110 and the outer wall of the body 210 can avoid the direct contact between the body 210 of the compressor 200 and the liquid accumulator 220, thereby avoiding the damage caused by the vibration and collision between the two.

[0067] In some embodiments, the first positioning portion 110 is welded to the outer wall of the body 210. The welding of the two can improve the connection strength of the first positioning portion 110 and the body 210, reduce the use of materials for connecting the two, and reduce the manufacturing cost. In addition, the first positioning portion 110 and the outer wall of the body 210 can also be connected by screwing, riveting, inserting or clamping, and the like, which are not limited in the present application.

[0068] In some embodiments, the second positioning portion 130 is welded to the outer wall of the liquid accumulator 220. In the case where the clamp and the connecting piece 150 cooperate to fix the liquid accumulator support 100 and the liquid accumulator 220, the above-mentioned arrangement can further improve the connection strength of the liquid accumulator support 100 and the liquid accumulator 220. In addition, the second positioning portion 130 and the liquid accumulator 220 can also be connected by screwing, riveting, inserting or clamping, and the like, which are not limited in the present application.

[0069] Continuing to refer to Figure 5 In some embodiments, the length of the connecting portion 120 from the first positioning portion 110 to the second positioning portion 130 is L, and the diameter of the through hole 121 is d, which satisfies: 1.3d < L. The above-mentioned arrangement can avoid that the diameter of the through hole 121 is too large to affect the strength of the connecting portion 120 of the liquid accumulator support 100, and at the same time avoid that the size of the component connected with the through hole 121 is too large to cause vibration and collision with the first positioning portion 110 or the liquid accumulator 220 after being inserted into the gap 111 between the first positioning portion 110 and the liquid accumulator 220.

[0070] In some embodiments, the liquid accumulator holder 100 further comprises a clamp (not shown in the figures). The clamp has two ends connected to the connecting portion 120 with the through hole 121 and the support arm 140, respectively. The first positioning portion 110, the connecting portion 120, the second positioning portion 130, the support arm 140 and the clamp collectively clamp the liquid accumulator 220. Specifically, the clamp tightly clamps the liquid accumulator 220 based on the cooperation of the connecting portion 120 and the through hole 121, so as to fix the body 210 of the compressor 200 and the liquid accumulator 220, and avoid the liquid accumulator 220 and the body 210 of the compressor 200 from shaking and moving.

[0071] With continued reference to Figure 4 、 Figure 5 and Figure 6 , in some embodiments, the liquid accumulator holder 100 further comprises a connecting piece 150. One end of the connecting piece 150 penetrates through the through hole 121 and is located in the gap 111, and the other end of the clamp is connected to the connecting portion 120 through the connecting piece 150 via the through hole 121. That is, the liquid accumulator holder 100 of the present application adopts a fixing mode in which the clamp and the connecting piece 150 cooperate, for fixing the body 210 of the compressor 200 and the liquid accumulator 220. The above arrangement can avoid the interference between the connecting piece 150 and the liquid accumulator 220 or the first connecting portion 120, by providing the through hole 121 in the connecting portion 120, and the new position of the through hole 121 enables the connecting piece 150 to be just located in the gap 111 between the liquid accumulator holder 100 and the liquid accumulator 220 after the connecting piece 150 is assembled. In addition, the connecting piece 150 is based on the projection of the bottom plate of the refrigeration equipment, and the mounting hole 231 of the bottom foot 230 is based on the projection of the bottom plate, so as to further avoid the interference between the connecting piece 150 and the mechanical hand for mounting the bottom foot 230 of the compressor 200 when the bottom foot 230 of the compressor 200 is mounted.

[0072] In some embodiments, the through hole 121 can be a bolt hole, and the connecting piece 150 can be a bolt and a nut. One end of the support arm 140 is screwed to the connecting portion 120 through the bolt, the nut and the bolt hole. The through hole 121 and the connecting piece 150 of the present application can also be other cooperation modes such as riveting, insertion, welding or clamping, and the present application does not limit this.

[0073] The liquid accumulator support 100 can form a space for the mechanical arm to vertically extend downwards and install the bottom foot 230 by designing the structure and span parameters of the liquid accumulator support 100 under the condition that the body 210, the liquid accumulator 220 and the bottom foot 230 are in the optimal balanced relative position, thereby avoiding the interference between the support arm 140 and the mechanical arm for installing the bottom foot 230 when the bottom foot 230 of the compressor 200 is installed.

[0074] In another aspect, with reference to Figure 6 The embodiment of the utility model provides a compressor 200, including: body 210;Liquid accumulator 220;Above-mentioned liquid accumulator support 100, wherein, liquid accumulator 220 is connected to body 210 through liquid accumulator support 100.

[0075] The compressor 200 of the utility model can form a mechanical arm space above the bottom foot 230 on the side of the liquid accumulator support 100 without the support arm 140, thereby avoiding the interference between the support arm 140 and the mechanical arm for installing the bottom foot 230 when the bottom foot 230 of the compressor 200 is installed.

[0076] In another aspect, with reference to

[0077] In another aspect, with reference to Figure 8 The embodiment of the utility model provides a compressor 200's installation method for installing the compressor 200, including:

[0078] S110, first positioning part 110 is fixedly connected with body 210;

[0079] S120, second positioning part 130 is fixedly connected with liquid accumulator 220;

[0080] S130, after bottom foot 230 is vertically extended downwards by mechanical arm and passes through the space, the fixed connection of the bottom plate of refrigeration equipment is realized by the screwing of bolt and nut.

[0081] The compressor further comprises a clamp, a connecting piece 150, and a through hole 121 of the penetrating connecting part 120, and the installation method for installing the compressor 200 can further comprise the following steps after step S120 and before step S130:

Specifically, the clamp tightly holds the liquid accumulator 220 based on the cooperation of the connecting part 120 and the through hole 121, so as to fix the body 210 of the compressor 200 and the liquid accumulator 220, avoid vibration and shaking of the liquid accumulator 220 and the body 210 of the compressor 200, and further improve the connection strength between the liquid accumulator support 100 and the liquid accumulator 220 on the basis of welding of the second positioning part 130 and the liquid accumulator 220.

[0083] It can be understood that the specific setting mode of the accommodation area of the mechanical hand of the compressor 200 can refer to the foregoing embodiment of the liquid accumulator support 100, and details are not described herein.

[0084] The installation method of the compressor 200 can form a mechanical hand accommodation area above the foot 230 by canceling the supporting arm 140 on one side of the existing liquid accumulator support 100 and the span parameter design of the liquid accumulator support 100, so as to avoid interference between the supporting arm 140 and the mechanical hand for installing the foot 230 of the compressor 200 when the foot 230 of the compressor 200 is installed.

In other embodiments, the above steps of the method can also exchange the order of writing and implementation, and are not limited thereto.

[0086] In summary, the liquid accumulator support, the compressor and the refrigeration equipment can cancel the supporting arm on one side of the existing liquid accumulator support and the span parameter design of the liquid accumulator support, so as to avoid interference between the compressor support and the mechanical hand for installing the foot of the compressor when the foot of the compressor is installed.
