Detailed Implementation

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0035] The following is for reference. Figures 1-5 A housing assembly 100 of a compressor according to an embodiment of the present invention is described.

[0036] like Figure 1 and Figure 2 As shown, the housing assembly 100 of the compressor according to an embodiment of the present invention includes: a body portion 10.

[0037] like Figure 1 and Figure 2 As shown, the body portion 10 includes an end plate 11 and an annular peripheral wall plate 12. The peripheral wall plate 12 extends from the periphery of the end plate 11 toward a first direction X1. A first portion 111 of the end plate 11 protrudes toward a direction opposite to the first direction X1 to define a mounting platform 111a. The mounting platform 111a is used to mount at least one of a terminal block 20, an exhaust pipe 30, a temperature sensing element 40, and a fastener 50. A second portion 112 of the end plate 11 for connecting the peripheral wall plate 12 and the mounting platform 111a is formed into a curved shape protruding toward a second direction X2.

[0038] This reduces the planar area of ​​the end plate 11, thereby improving the airflow field during the operation of the compressor 1000 by utilizing the curved second part 112, reducing the impact pulsation of gas on the housing assembly 100, and improving the fixed frequency of the housing assembly 100, reducing the resonance between the housing assembly 100 and the compressor 1000, thus improving noise and vibration.

[0039] For example Figure 5 As shown, the compressor 1000 includes an upper housing 200, a main housing 300, and a lower housing 400. In this embodiment, the housing assembly 100 can be the upper housing 200, the main housing 300, or the lower housing 400 of the compressor 1000. In the following embodiment, the housing assembly 100 is illustrated by taking the upper housing 200 as an example.

[0040] The upper housing 200 includes an end plate 11 and an annular peripheral wall plate 12, the annular peripheral wall plate 12 being along a first direction X1 (e.g., Figure 1The end plate 11 extends below the compressor chamber 1000 for connection to the main housing 300. The end plate 11 is located at the upper end of the compression chamber of the compressor 1000 and is used to close the upper end of the compression chamber. The first direction X1 is... Figure 1 , Figures 3-5 The X1 direction in the equation.

[0041] Furthermore, such as Figure 1 As shown, the end plate 11 includes a first part 111 and a second part 112, the first part 111 facing a direction opposite to the first direction X1 (e.g., Figure 1 The upper part of the upper housing 200 protrudes to define the mounting platform 111a. The mounting platform 111a is used to install the terminal block 20, the exhaust pipe 30, the temperature sensing element 40, and the fastener 50. The fastener 50 can be a fixing bolt for fixing the upper housing 200 to the main housing 300. The terminal block 20 is used for external wiring. The temperature sensing element 40 is used to collect the temperature information of the upper housing 200. The exhaust pipe 30 is used to discharge the compressed gas in the compression chamber.

[0042] The second part 112 is used to connect the peripheral wall plate 12 and the mounting platform 111a, and the second part 112 is formed into a curved surface shape protruding towards the second direction X2, wherein the second direction X2 can be a direction intersecting the first direction X1, for example... Figure 1 The X2 direction in the middle.

[0043] Curved surface shapes include, but are not limited to: spherical shapes, arc shapes, or shapes formed by connecting multiple spherical shapes, and are not limited here.

[0044] It should be noted that during the operation of the compressor 1000, the gas in the compression chamber will impact the upper housing 200. In related technologies, most of the upper housing 200 is flat, which will result in a lower natural frequency of the upper housing 200, making it easy to resonate with the relevant frequency when the compressor 1000 is running. Furthermore, the large area of ​​flat surface will affect the airflow field, increase the impact pulsation of gas on the housing assembly 100, and cause problems such as noise and vibration.

[0045] In this application, by setting the second part 112 as a curved shape convex toward the second direction X2, which intersects with the first direction X1, when the gas impacts the upper housing 200, the side of the second part 112 facing the gas is concave due to its non-planar shape. This guides the gas when it impacts the second part 112, thus improving the airflow field and reducing the impact pulsation of the gas on the housing assembly 100. Furthermore, the curved shape design reduces the planar area of ​​the end plate 11, thereby improving the fixed frequency of the housing assembly 100 and reducing the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0046] According to an embodiment of the present invention, the housing assembly 100 of the compressor reduces the planar area of ​​the end plate 11 by forming the second part 112 connecting the peripheral wall plate 12 and the mounting platform 111a into a curved shape protruding in the second direction X2. In this way, during the use of the compressor 1000, the curved shape of the second part 112 can improve the airflow field, reduce the impact pulsation of gas on the housing assembly 100, and help improve the fixed frequency of the housing assembly 100, reduce the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0047] In some embodiments, such as Figure 1 As shown, the second part 112 is formed into a spherical shape.

[0048] For example, the second part 112 is formed as a spherical shape that protrudes outward in the second direction X2, which makes the shape of the second part 112 simpler, reduces the difficulty of setting the second part 112, and makes the surface of the second part 112 smoother, making it easier to further reduce the planar area of ​​the end plate 11. In this way, during the use of the compressor 1000, the curved shape of the second part 112 can improve the airflow field, reduce the impact pulsation of gas on the housing assembly 100, and help improve the fixed frequency of the housing assembly 100, reduce the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0049] In some embodiments, on the same projection plane perpendicular to the first direction X1, the projected area of ​​the end plate 11 is S, the projected area of ​​the mounting platform 111a is S1, and satisfies: 22.3% ≤ S1 / S ≤ 33.3%.

[0050] Therefore, it can be ensured that the installation platform 111a can simultaneously meet the arrangement of the wiring terminal 20, exhaust pipe 30, temperature sensing element 40 and fixing member 50, as well as... Figure 2As shown, the minimum area that the mounting platform 111a can have when it has at least three support areas 112b is shown.

[0051] This allows the curved surface area of ​​the second part 112 to be maximized, thereby minimizing the planar area of ​​the end plate 11. As a result, during the operation of the compressor 1000, the curved shape of the second part 112 can improve the airflow field, reduce the impact pulsation of gas on the housing assembly 100, and help improve the fixed frequency of the housing assembly 100, reduce the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0052] For example, if the housing assembly 100 is the upper housing 200, then the "support area 112b" refers to the three areas of the upper housing 200 used for support with the tooling after it is flipped over. These three areas cannot interfere with the arrangement of the terminal block 20, the exhaust pipe 30, the temperature sensing element 40, and the fixing element 50. Therefore, the minimum area of ​​the mounting platform 111a must include at least the arrangement area of ​​the terminal block 20, the exhaust pipe 30, the temperature sensing element 40, and the fixing element 50, as well as the area of ​​the three support areas 112b.

[0053] It should be noted that the purpose of setting three support areas 112b is to ensure that the upper shell 200 forms a three-point support with the tooling after flipping, similar to the three vertices of a triangle, thereby utilizing the stability of the triangle to enhance the stability of the upper shell 200 when it is supported by the tooling after flipping.

[0054] For example, on the same projection plane perpendicular to the first direction X1, the ratio of the projected area S of the end plate 11 to the projected area S1 of the mounting platform 111a is S1 / S = 25%, or the ratio of the projected area S of the end plate 11 to the projected area S1 of the mounting platform 111a is S1 / S = 28%, or the ratio of the projected area S of the end plate 11 to the projected area S1 of the mounting platform 111a is S1 / S = 30%.

[0055] For example, the body 10 of the housing assembly 100 is an upper housing 200, and the upper housing 200 has various types. Among them, the K-series upper housing 200 has a maximum outer diameter of 90.3 mm, and the corresponding projected area S1 of the mounting platform 111a is 6404 mm². 2 The maximum outer diameter of the upper housing 200 in the N series is 101.4 mm, and the corresponding projected area S1 of the mounting platform 111a is 8075 mm². 2 The maximum outer diameter of the upper housing 200 in the M series is 110.3 mm, and the corresponding projected area S1 of the mounting platform 111a is 9555 mm². 2For the upper housing 200 with a maximum outer diameter of 101.4 mm, the preferred proportion of the projected area S1 of the corresponding mounting platform 111a is 26.4%.

[0056] When the projected area S of the end plate 11 and the projected area S1 of the mounting platform 111a satisfy the above-mentioned proportional relationship, the curved surface area of ​​the second part 112 can be maximized, thereby minimizing the planar area of ​​the end plate 11. In this way, during the use of the compressor 1000, the curved shape of the second part 112 can improve the airflow field, reduce the impact pulsation of gas on the housing assembly 100, and help improve the fixed frequency of the housing assembly 100, reduce the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0057] In some embodiments, when the area of ​​the mounting platform 111a and the area of ​​the end plate 11 satisfy the proportional relationship described in the above embodiments, the larger the outer diameter of the end plate 11, the larger the area of ​​the second part 112.

[0058] Therefore, the curved surface area of ​​the second part 112 can be maximized, thereby minimizing the planar area of ​​the end plate 11. In this way, during the use of the compressor 1000, the curved shape of the second part 112 can improve the airflow field, reduce the impact pulsation of gas on the housing assembly 100, and help improve the fixed frequency of the housing assembly 100, reduce the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0059] In some embodiments, such as Figure 1 As shown, the outer diameter of the end plate 11 is D1, and satisfies: 90.3mm≤D1≤110.3mm.

[0060] For example, the outer diameter of the end plate 11 can be D1 = 95mm, or D1 = 100mm, or D1 = 100.5mm, or D1 = 105mm. That is, when the outer diameter of the end plate 11 meets the above value range, when the housing assembly 100 is the upper housing 200, the design of the end plate 11 can meet the size requirements of the K series upper housing 200, N series upper housing 200, and M series upper housing 200 commonly available in the market. Therefore, it is not necessary to open a mold for the housing assembly 100 separately, so as to reduce production costs.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the connection between the second part 112 and the mounting platform 111a is a rounded transition.

[0062] Therefore, by setting the connection between the second part 112 and the mounting platform 111a to be an arc transition, the connection between the second part 112 and the mounting platform 111a is an arc surface. This allows for a further reduction in the planar area of ​​the end plate 11. In this way, during the use of the compressor 1000, the curved shape of the second part 112 can improve the airflow field, reduce the impact pulsation of gas on the housing assembly 100, and help improve the fixed frequency of the housing assembly 100, reduce the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0063] Meanwhile, the connection between the second part 112 and the mounting platform 111a is a rounded transition, which allows the connection to form a reinforcing rib. This enhances the connection strength and increases the overall structural strength of the end plate 11.

[0064] In some embodiments, such as Figure 4 As shown, in the first direction X1, the opposite sidewalls 1111 of the mounting platform 111a are both planes.

[0065] Therefore, by setting the opposite sidewalls 1111 of the mounting platform 111a in the first direction X1 to be flat, the surface of the mounting platform 111a is made more neat, which makes it easier to reduce the processing difficulty of the mounting platform 111a. At the same time, it can meet the requirements of the mounting plane for the terminal 20, exhaust pipe 30, temperature sensing element 40 and fixing member 50, so that at least one of the terminal 20, exhaust pipe 30, temperature sensing element 40 and fixing member 50 can be mounted on the plane, which helps to reduce the installation difficulty.

[0066] In some embodiments, such as Figure 3 and Figure 4 As shown, in the first direction X1, the first surface 1112 of the mounting platform 111a is provided with a mounting groove 13 for mounting the temperature sensing element 40.

[0067] It should be noted that, in the first direction X1, the first surface 1112 of the mounting platform 111a includes, as follows: Figure 4 The upper surface and / or such Figure 4 The lower surface of the middle.

[0068] Therefore, by setting the mounting groove 13, the temperature sensing element 40 can be installed into the mounting groove 13, thereby reducing the assembly difficulty of the enhanced temperature sensing element 40. The mounting groove 13 can also fix and limit the temperature sensing element 40, thereby reducing the shaking of the temperature sensing element 40 and enhancing the assembly stability of the temperature sensing element 40 and the mounting platform 111a.

[0069] For example, the temperature sensing element 40 can be snapped into the mounting groove 13, or the temperature sensing element 40 can be bonded to the mounting groove 13. Alternatively, the temperature sensing element 40 can be placed in the mounting groove 13 and the upper side of the temperature sensing element can be limited by a cover plate. Of course, the method of fixing the temperature sensing element 40 in the mounting groove 13 can also be other methods, which are not limited here.

[0070] In some embodiments, such as Figure 3 and Figure 4 As shown, the inner wall of the mounting groove 13 is formed as an arc-shaped surface 131.

[0071] It should be noted that the temperature sensing element 40 is usually a cylindrical structure, that is, the outer wall of the temperature sensing element 40 is usually an arc surface.

[0072] Therefore, by setting the inner wall of the mounting groove 13 to an arc-shaped surface 131, the mounting groove 13 can better fit the shape of the temperature sensing element 40, thereby enhancing the structural stability of the temperature sensing element 40 in the mounting groove 13. At the same time, it is easy to increase the contact area between the temperature sensing element and the inner wall of the mounting groove 13. It is worth noting that the temperature sensing element 40 usually collects temperature and other data by collecting the part of the temperature sensing element 40 in contact with the end plate 11.

[0073] Therefore, by setting the inner wall of the mounting groove 13 to be an arc-shaped surface 131, it is easier to increase the area of ​​the temperature sensing element 40 that collects data, thereby improving the accuracy and efficiency of data acquisition.

[0074] In some embodiments, the compressor housing assembly 100 further includes a temperature sensing element 40, which contacts the mounting groove 13.

[0075] Specifically, the temperature sensing element 40 and the inner wall of the mounting groove 13 are in surface-to-surface contact. Compared with "line-to-surface contact" or "point-to-surface contact", surface-to-surface contact can have a larger contact area and better contact stability. This makes it easier to increase the contact area between the temperature sensing element 40 and the inner wall of the mounting groove 13, thereby increasing the area of ​​the temperature sensing element 40 that collects data, and thus improving the accuracy and stability of data acquisition.

[0076] In some embodiments, in the first direction X1, the diameter of the temperature sensing element 40 is D, the contact area between the inner wall of the mounting groove 13 and the temperature sensing element 40 is S2, and satisfies: S2=1 / 8πD 2 .

[0077] This ensures that the temperature sensing element 40 has sufficient contact area with the inner wall of the mounting groove 13, thereby facilitating improved data acquisition accuracy and stability.

[0078] For example, the temperature sensing element 40 has a cylindrical structure, and its diameter is D in the first direction X1. In this case, if a cross-section is taken in the first direction X1, the area of ​​the circle at the cross-section is 1 / 4πD. 2 The contact area between the inner wall of the mounting groove 13 and the temperature sensing element 40 is S2 = 1 / 8πD 2 In other words, the contact area between the inner wall of the mounting groove 13 and the temperature sensing element 40 is half the area of ​​the circle at the aforementioned cross-section.

[0079] Therefore, by limiting the dimensions as described above, it can be ensured that the temperature sensing element 40 and the inner wall of the mounting groove 13 have sufficient contact area, thereby facilitating the improvement of data acquisition accuracy and acquisition stability.

[0080] In some other embodiments, the contact area S2 between the inner wall of the mounting groove 13 and the temperature sensing element 40 and the diameter D of the temperature sensing element 40 can also satisfy: S2 > 1 / 8πD 2 Or S2 < 1 / 8πD 2 No restrictions are imposed here.

[0081] In some embodiments, in the first direction X1, the diameter of the temperature sensing element 40 is D, and as shown... Figure 4 As shown, the depth of the mounting groove 13 is H, and it satisfies: D / 3≤H≤D.

[0082] For example, H = 1 / 3D, H = 1 / 2D, or H = 3 / 5D, or H = 7 / 10D, H = D, that is, when the depth of the mounting groove 13 and the diameter D of the temperature sensing element 40 meet the above value range, it can ensure that the temperature sensing element 40 and the inner wall of the mounting groove 13 have sufficient contact area, thereby facilitating the improvement of data acquisition accuracy and acquisition stability. At the same time, it makes the height of the temperature sensing element 40 protruding from the mounting platform 111a smaller, which is easier for the subsequent arrangement of the bracket for fixing the temperature sensing element 40.

[0083] In some other embodiments, the depth of the mounting groove 13 and the diameter D of the temperature sensing element 40 may also satisfy: H > D, which is not limited here.

[0084] In some embodiments, such as Figure 2 As shown, in the axial direction of the mounting groove 13 (e.g.) Figure 2 In the Y direction, at least one end of the mounting slot 13 is open.

[0085] "At least one end of the mounting groove 13 is open" includes one axial end of the mounting groove 13 being open, or the other axial end of the mounting groove 13 being open, or both axial ends of the mounting groove 13 being open, and is not limited here.

[0086] This makes it easier to install the temperature sensing element 40 into the mounting groove 13 from the axially open end of the mounting groove 13, thereby reducing the assembly difficulty of the temperature sensing element 40.

[0087] Meanwhile, since at least one end of the mounting groove 13 is open in the axial direction, when the axial length of the temperature sensing element 40 is long, the axial end of the temperature sensing element 40 can extend out from the open end of the mounting groove 13, thereby avoiding the end of the temperature sensing element 40. This makes it easier to reduce the restriction of the mounting groove 13 on the axial length of the temperature sensing element 40, so that the temperature sensing element 40 with a larger axial length can also be installed in the mounting groove 13.

[0088] The present invention also proposes a compressor 1000.

[0089] The compressor 1000 according to an embodiment of the present invention includes: the housing assembly 100 of the compressor according to any of the above embodiments.

[0090] For example, compressor 1000 can be applied to equipment such as air conditioners, and compressor 1000 includes: upper housing 200, main housing 300, lower housing 400 and liquid receiver 500, wherein the upper housing 200 is constructed as housing assembly 100, and a liquid receiver 500 is mounted on the mounting platform 111a of end plate 11.

[0091] The main housing 300 contains a motor and pump assembly, a terminal block 20, an exhaust pipe 30, a temperature sensing element 40, and a fastener 50. The fastener 50 can be a fixing bolt for fixing the upper housing 200 to the main housing 300. The terminal block 20 is used for external wiring. The temperature sensing element 40 is used to collect temperature information of the upper housing 200. The exhaust pipe 30 is used to discharge compressed gas from the compression chamber.

[0092] According to an embodiment of the compressor 1000 of the present invention, the housing assembly 100 reduces the planar area of ​​the end plate 11 by forming the second part 112 of the connecting peripheral wall plate 12 and the mounting platform 111a into a curved shape protruding in the second direction X2. In this way, during the use of the compressor 1000, the curved second part 112 can improve the airflow field, reduce the impact pulsation of gas on the housing assembly 100, and help improve the fixed frequency of the housing assembly 100, reduce the resonance between the housing assembly 100 and the compressor 1000, thereby improving noise and vibration.

[0093] The present invention also proposes an air conditioner.

[0094] An air conditioner according to an embodiment of the present invention includes: a compressor 1000 according to any of the above embodiments.
