Description

TECHNICAL FIELD

[0001] The utility model relates to a compressor technical field, specifically, relate to a liquid accumulator and compressor. BACKGROUND

[0002] At present, the compressor liquid accumulator in the prior art, such as Figures 10 to 14 As shown in the figure, the upper cover 2' of the liquid accumulator shell 1' and the suction pipe 3' adopt a gap-welding cooperation mode, and the upper cover 2' only has a straight section 4', however, during the welding operation, the suction pipe often deviates to one side, which makes the welding material on one side unable to be effectively filled, thereby causing insufficient welding strength and low pressure resistance value. During the operation of the compressor, the welding part of the upper cover and the suction pipe is prone to leakage, and it is difficult to meet the use pressure requirement during the operation of the compressor. Especially when using high-pressure refrigerants such as CO2 refrigerant, since the pressure thereof is about 3 to 4 times that of conventional R32 refrigerant, the pressure resistance requirement of the connecting piece is higher. The above-mentioned defects existing in the gap cooperation and welding mode of the inner hole of the upper cover of the rotary compressor liquid accumulator and the suction pipe are more prominent, which seriously restricts the reliable operation of the compressor under high-pressure refrigerant working conditions.

[0003] Therefore, how to design a liquid accumulator capable of ensuring welding strength to improve the pressure resistance value has become a problem to be solved at present. UTILITY MODEL CONTENTS

[0004] The utility model aims at least solve the problems, such as insufficient welding strength between the suction pipe and the content of the liquid accumulator, and low pressure resistance value.

[0005] Therefore, the first aspect of the utility model provides a kind of liquid accumulator.

[0006] The second aspect of the utility model provides a kind of compressor.

[0007] Therefore, the first aspect of the utility model provides a kind of liquid accumulator.

[0008] The utility model provides a liquid accumulator, including shell, convex part and pipe, the convex part sets up on the shell, and the convex part is provided with the installation passageway with the inside communication of shell, so that can set up one end of pipe in the installation passageway, sets up the other end of pipe in the shell, to realize the communication of shell inside and outside through pipe. The mounting gap between the outer circumferential surface of pipe and the inner wall surface of installation passageway, the mounting gap close to one end of pipe is less than the mounting gap close to the other end of pipe, namely, from one end of pipe to the other end, the mounting gap can be gradually increased, or is abruptly increased, etc., so that can set up connecting structure or connecting piece in big mounting gap, for example, when adopting welding mode to connect pipe and convex part, can place the welding strip or solder in big mounting gap, so that even if pipe deviates to one side, can provide sufficient layout space for welding strip or solder, further effectively improve the welding strength, enhance the pressure resistance value of liquid accumulator, ensure the stability and reliability of liquid accumulator in the use process.

[0009] According to the liquid accumulator, the following additional technical features can be further provided.

[0010] In some embodiments, optionally, the convex part is arranged outside the shell, or the convex part is arranged inside the shell.

[0011] In the embodiments, the convex part can be arranged outside or inside the shell, and the arrangement can be determined according to actual conditions.

[0012] In some embodiments, optionally, the convex part comprises a gradually expanding section and a straight section, the straight section is arranged between one end of the pipe and the gradually expanding section, the gradually expanding section or the straight section is connected with the shell, the cross-sectional area of the installation passageway corresponding to the gradually expanding section gradually increases from one end of the pipe to the other end of the pipe, and at least part of the pipe is located in the installation passageway corresponding to the straight section.

[0013] In the embodiments, the protrusion includes a straight section and a diverging section, the straight section is arranged between one end of the conduit and the diverging section, and the diverging section or the straight section is connected with the shell. It can be understood that when the protrusion is arranged outside the shell, the straight section can be connected with the shell. When the protrusion is arranged inside the shell, the diverging section can be connected with the shell. The cross-sectional area of the mounting channel corresponding to the diverging section gradually increases from one end of the conduit to the other end of the conduit, that is, the opening of the mounting channel gradually increases from the one end of the conduit to the other end of the conduit. The structure of the opening increasing more and more can include various forms, for example, uniformly increasing at a certain ratio, or suddenly increasing, etc. Due to the arrangement of the diverging section, the gap between the conduit and the mounting channel corresponding to the diverging section gradually increases from one end of the conduit to the other end of the conduit. Therefore, when the conduit is fixedly connected, the connecting structure or connecting piece can be arranged in the gap between the conduit and the mounting channel corresponding to the diverging section. For example, when the conduit and the protrusion are connected by welding, the welding strip or solder can be arranged between the conduit and the diverging section. In this way, even if the conduit deviates to one side, the welding strip or solder can also be provided with sufficient layout space, thereby effectively improving the welding strength, enhancing the pressure resistance value of the liquid accumulator, and ensuring the stability and reliability of the liquid accumulator in use. At the same time, arranging at least part of the conduit in the mounting channel corresponding to the straight section can limit the conduit in the radial direction through the mounting channel of the straight section, so as to prevent the conduit from tilting, thereby facilitating the fixation and connection of the conduit.

[0014] In some embodiments, optionally, the length of the straight section is greater than or equal to 1 / 10 of the length of the conduit and less than or equal to 5 mm in the direction from one end of the conduit to the other end of the conduit.

[0015] In the embodiments, the length of the straight section is greater than or equal to 1 / 10 of the length of the conduit and less than or equal to 5 mm in the direction from one end of the conduit to the other end of the conduit. This arrangement can ensure that the conduit is not prone to unstable conditions such as shaking and deviation during assembly and subsequent use, thereby improving the installation stability and connection reliability of the conduit.

[0016] In some embodiments, optionally, the inner surface of the mounting channel corresponding to the diverging section is a conical surface, and the inner surface of the mounting channel corresponding to the diverging section tilts away from the axis of the conduit from one end of the conduit to the other end of the conduit.

[0017] In the embodiments, the inner surface of the mounting channel corresponding to the diverging section is provided as a tapered surface, which is inclined away from the axis of the conduit from one end of the conduit to the other end. With such an arrangement, the tapered surface can guide the conduit during installation, facilitating smooth insertion of the conduit and reducing installation difficulty and operation complexity, and improving assembly efficiency. In addition, for subsequent connection processes such as welding, the tapered surface allows the solder to flow and distribute naturally according to its inclination angle when filling the gap, making it easier to achieve uniform and full welding effect, enhancing the strength and stability of the welded connection, and effectively preventing weak points in the connection caused by uneven solder filling, thereby improving the overall pressure resistance and sealing performance of the liquid reservoir, ensuring reliable connection between the conduit and the protrusion in high-pressure environments or long-term operation conditions, and ensuring normal operation and service life of the liquid reservoir.

[0018] In some embodiments, the angle between the tapered surface and the axis of the conduit is greater than or equal to 10° and less than or equal to 60°.

[0019] In the embodiments, the angle between the tapered surface and the axis of the conduit can be greater than or equal to 10° and less than or equal to 60°. It can be understood that when the angle is less than 10°, the flaring degree of the diverging section is too gentle, which can cause the solder or connecting material to be difficult to form a connection layer with sufficient thickness and strength between the conduit and the mounting channel during welding or other connection processes, and can easily result in a loose connection, affecting the pressure resistance and overall stability of the liquid reservoir. Conversely, if the angle is greater than 60°, the flaring of the diverging section is too steep. On the one hand, this can increase the difficulty of positioning the conduit when it is inserted into the mounting channel, and can easily result in poor installation such as eccentricity or inclination, thereby affecting the uniformity and reliability of subsequent connection. On the other hand, the large angle can cause uneven stress distribution in the connection structure when it is subjected to pressure, resulting in excessive local stress and increasing the risk of connection failure, reducing the durability and safety of the liquid reservoir. Therefore, controlling the angle to be between 10° and 60° can ensure smooth installation of the conduit and effective filling of the connecting material.

[0020] In some embodiments, the length of the diverging section in the direction from one end of the conduit to the other end of the conduit is greater than or equal to 1 mm and less than or equal to 5 mm.

[0021] In some embodiments, the length of the gradually expanding section is greater than or equal to 1 mm and less than or equal to 5 mm in the direction from one end of the conduit to the other end of the conduit. It can be understood that when the length of the gradually expanding section is less than 1 mm, the flaring effect is not obvious, and it is difficult to effectively increase the gap space between the conduit and the mounting channel. This can result in insufficient filling space of the solder or connecting material when performing the connection operation (such as welding), which cannot fully wrap the conduit, thereby affecting the firmness and stability of the connection, reducing the overall pressure resistance of the liquid reservoir, and easily causing connection failure or leakage in a high-pressure environment. If the length of the gradually expanding section exceeds 5 mm, the overall structure of the protruding portion will be too long, which can cause installation difficulties in some application scenarios with compact space layout requirements.

[0022] In some embodiments, the conduit is a tapered pipe, and the cross-sectional area of the conduit gradually decreases in the direction from one end of the conduit to the other end of the conduit.

[0023] In some embodiments, the conduit can also be set as a tapered pipe, so that the thicker end of the tapered pipe is arranged in the mounting channel. In this way, the mounting gap between the conduit and the mounting channel gradually increases in the direction from one end of the conduit to the other end of the conduit, so that the connecting structure or connecting member can be arranged in the large mounting gap. Even if the conduit deviates to one side, sufficient layout space can be provided for the solder strip or solder, thereby effectively improving the welding strength, enhancing the pressure resistance value of the liquid reservoir, and ensuring the stability and reliability of the liquid reservoir during use.

[0024] In some embodiments, the conduit includes a first pipe section and a second pipe section, the outer diameter of the first pipe section is greater than the outer diameter of the second pipe section, the first pipe section is arranged close to one end of the conduit, and the second pipe section is arranged away from the other end of the conduit. The first pipe section is arranged in the mounting channel, and at least part of the second pipe section is arranged in the mounting channel.

[0025] In some embodiments, the conduit can be arranged in the form of a first pipe section and a second pipe section. The outer diameter of the first pipe section is greater than the outer diameter of the second pipe section, the first pipe section is arranged close to one end of the conduit, and the second pipe section is arranged away from the other end of the conduit. The first pipe section is arranged in the mounting channel, and at least part of the second pipe section is arranged in the mounting channel. In this way, because the outer diameter of the first pipe section is larger and the outer diameter of the second pipe section is smaller, a relatively large mounting gap is formed between the second pipe section and the inner wall of the mounting channel, so that the connecting structure or connecting member can be arranged in the large mounting gap. Even if the conduit deviates to one side, the gap can provide sufficient layout space for the solder strip or solder. In turn, the welding strength can be effectively improved, the pressure resistance value of the liquid reservoir can be enhanced, and the stability and reliability of the liquid reservoir during use can be effectively ensured.

[0026] In some embodiments, optionally, the outer side wall of the conduit is provided with a groove recessed to the inside of the conduit, part of the groove is located in the mounting channel, and part of the groove is located outside the shell.

[0027] In some embodiments, optionally, the outer side wall of the conduit is provided with a groove recessed to the inside of the conduit, part of the groove is located in the mounting channel, and part of the groove is located outside the shell.

[0028] In some embodiments, optionally, the conduit and the protruding part are welded.

[0029] In some embodiments, optionally, the conduit and the protruding part are welded.

[0030] In some embodiments, optionally, the protruding part is integrally formed with the shell.

[0031] In some embodiments, optionally, the protruding part is integrally formed with the shell.

[0032] The second aspect of the utility model provides a kind of compressor, comprising: the liquid accumulator in any one of the technical solutions of the first aspect.

[0033] The compressor provided in the present application includes the liquid accumulator in any one of the technical solutions of the first aspect. Therefore, the compressor provided in the present application also has all the beneficial effects of the liquid accumulator in any one of the technical solutions of the first aspect, which will not be repeated here.

[0034] In some embodiments, optionally, the compressor is a rotary compressor.

[0055] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be described in further detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0056] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced without other different ways from those described herein, therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0057] Reference will now be made to the following Figures 1 to 9 A reservoir and a compressor according to some embodiments of the present application are described.

[0058] According to one embodiment of the first aspect of the present application, as Figures 1 to 9 The first aspect of the present application proposes a reservoir 1, comprising a housing 10, a protrusion 11 and a conduit 12. The protrusion 11 is arranged on the housing 10, and the protrusion 11 has a mounting channel 116 which is in communication with the inside of the housing 10. One end of the conduit 12 is arranged in the mounting channel 116, and the other end of the conduit 12 is located outside the housing 10, and there is a mounting gap between the outer peripheral surface of the conduit and the inner wall surface of the mounting channel. The mounting gap near the one end of the conduit is smaller than the mounting gap near the other end of the conduit.

[0059] The utility model provides a liquid accumulator 1, including casing 10, convex part 11 and pipe 12. Convex part 11 sets up on casing 10, and the mounting channel 116 that is communicated with the inside of casing 10 is set up on convex part 11, so that the one end of pipe 12 can be set in mounting channel 116, and the other end of pipe 12 is set in casing 10, to realize the communication of casing 10 inside and outside through pipe 12. The mounting gap 13 between the outer circumferential surface of pipe 12 and the inner wall surface of mounting channel 116, the mounting gap 13 close to one end of pipe 12 is less than the mounting gap 13 close to the other end of pipe 12, that is, from one end of pipe 12 to the other end, the mounting gap 13 can be gradually increased, or be increased suddenly, etc., so that the connecting structure or connecting piece can be set in the big mounting gap 13, for example, when pipe 12 and convex part 11 are connected by welding, the welding strip or solder can be placed in the big mounting gap 13, so that even if pipe 12 deviates to one side, the welding strip or solder can also provide sufficient layout space, to effectively improve the welding strength, enhance the pressure resistance value of liquid accumulator, and ensure the stability and reliability of liquid accumulator in use.

[0060] In some embodiments, optionally, as shown in Figure 1 and Figure 4 The convex part 11 is arranged outside the casing 10, or the convex part 11 is arranged inside the casing 10.

[0061] In these embodiments, the convex part 11 can be arranged outside or inside the casing 10, and can be arranged according to actual conditions.

[0062] In some embodiments, optionally, as shown in Figure 2 and Figure 3 The convex part 11 includes a gradually expanding section 112 and a straight section 114, the straight section 114 is arranged between one end of the pipe 12 and the gradually expanding section 112, the gradually expanding section 112 or the straight section 114 is connected with the casing 10, the cross-sectional area of the mounting channel 116 corresponding to the gradually expanding section 112 gradually increases from one end of the pipe 12 to the other end of the pipe 12, and at least part of the pipe 12 is located in the mounting channel 116 corresponding to the straight section 114.

[0063] In these embodiments, the protrusion 11 includes a gradually expanding section 112 and a straight section 114. The straight section 114 is disposed between one end of the conduit 12 and the gradually expanding section 112. The gradually expanding section 112 or the straight section 114 is connected to the housing 10. It is understood that when the protrusion 11 is disposed outside the housing 10, the straight section 114 can be connected to the housing 10. When the protrusion 11 is disposed inside the housing 10, the gradually expanding section 112 can be connected to the housing 10. The cross-sectional area of ​​the mounting channel 116 corresponding to the gradually expanding section 112 gradually increases from one end of the conduit 12 to the other end of the conduit 12. That is, from one end of the conduit 12 to the other end of the conduit 12, the opening of the mounting channel 116 gradually becomes larger. This structure of increasingly larger openings can include various forms, such as uniformly increasing at a certain ratio or increasing abruptly. Because this application includes a gradually expanding section 112, the gap between the conduit 12 and the corresponding mounting channel 116 gradually increases from one end of the conduit 12 to the other. Therefore, when fixing the conduit 12, a connecting structure or connector can be provided in the gap between the conduit 12 and the corresponding mounting channel 116. For example, when the conduit 12 and the protrusion 11 are connected by welding, welding strips or solder can be placed between the conduit 12 and the gradually expanding section 112. This provides sufficient space for the welding strips or solder even if the conduit 12 deviates to one side, thereby effectively improving the welding strength, enhancing the pressure resistance of the reservoir, and ensuring the stability and reliability of the reservoir during use. Simultaneously, by placing at least a portion of the conduit 12 within the mounting channel 116 corresponding to the straight section 114, the mounting channel 116 of the straight section 114 can radially limit the conduit 12, preventing it from tilting, thus facilitating the fixing and connection of the conduit 12.

[0064] In some embodiments, optionally, such as Figure 1 and Figure 3 As shown, the length of the straight section 114 along the direction from one end of the catheter 12 to the other end of the catheter 12 is ( Figure 3 As shown in L1, the length of catheter 12 is greater than or equal to that of catheter 12. Figure 1 (as shown in L3) 1 / 10, and less than or equal to 5mm.

[0065] In these embodiments, the length of the straight section 114 along the direction from one end of the conduit 12 to the other end of the conduit 12 is greater than or equal to 1 / 10 of the length of the conduit 12 and less than or equal to 5 mm. This arrangement ensures that the conduit 12 is less prone to shaking, displacement, or other unstable conditions during assembly and subsequent use, thereby improving the installation stability and connection reliability of the conduit 12.

[0066] In some embodiments, the length of the straight section 114 is optionally 5 mm along the direction from one end of the catheter 12 to the other end of the catheter 12.

[0067] In some embodiments, the length of the straight section 114 is optionally 4 mm along the direction from one end of the catheter 12 to the other end of the catheter 12.

[0068] In some embodiments, the length of the straight section 114 is optionally 3 mm along the direction from one end of the catheter 12 to the other end of the catheter 12.

[0069] In some embodiments, optionally, the inner surface of the mounting channel 116 corresponding to the expanding section 112 is a tapered surface 1122, extending from one end of the conduit 12 to the other end of the conduit 12, with the inner surface of the mounting channel 116 corresponding to the expanding section 112 along a direction away from the axis of the conduit 12. Figure 3 The direction indicated by X in the middle is tilted.

[0070] In these embodiments, the inner surface of the installation channel 116 corresponding to the expanding section 112 is set as a tapered surface 1122. From one end of the conduit 12 to the other end, the tapered surface 1122 is inclined in a direction away from the axis of the conduit 12. This setting allows the conduit 12 to be guided during installation, facilitating smooth insertion, reducing installation difficulty and operational complexity, and improving assembly efficiency. Secondly, for subsequent connection processes, such as welding, the tapered surface 1122 allows the solder to flow and distribute naturally according to its tilt angle when filling the gap, making it easier to achieve a uniform and full welding effect, enhancing the strength and stability of the welded connection, and effectively preventing weak points in the connection caused by uneven solder filling. This improves the overall pressure resistance and sealing performance of the reservoir 1, ensuring that the connection between the conduit 12 and the protrusion 11 remains reliable under high-pressure environments or long-term operating conditions, ensuring the normal operation and service life of the reservoir 1.

[0071] In some embodiments, the angle between the tapered surface 1122 and the axis of the conduit 12 is greater than or equal to 10° and less than or equal to 60°.

[0072] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of greater than or equal to 10° and less than or equal to 60°.

[0073] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of greater than or equal to 10° and less than or equal to 45°. Figure 3 Figure 3 In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of 10°.

[0074] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of 20°.

[0075] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of 30°.

[0076] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of 40°.

[0077] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of 50°.

[0078] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of 60°.

[0079] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of 60°.

[0080] In some embodiments, the taper surface 1122 and the axis of the conduit 12 can form an angle (indicated by a in the figure) of greater than or equal to 10° and less than or equal to 60°. Figure 3 Figure 3 In some embodiments, the length (indicated by L2 in the figure) of the taper surface 1122 along the conduit 12 from one end to the other end can be greater than or equal to 1 mm and less than or equal to 5 mm. ​​

[0081] In these embodiments, the length of the expanding section 112 along the direction from one end of the conduit 12 to the other end is greater than or equal to 1 mm and less than or equal to 5 mm. It is understood that when the length of the expanding section 112 is less than 1 mm, its flaring effect is not significant, making it difficult to effectively increase the gap between the conduit 12 and the installation channel 116. This can lead to insufficient filling space for the solder or connecting material during connection operations (such as welding), failing to fully enclose the conduit 12, thus affecting the strength and stability of the connection, reducing the overall pressure resistance of the reservoir 1, and making it prone to connection failure or even leakage under high pressure. Conversely, if the length of the expanding section 112 exceeds 5 mm, the overall structure of the protrusion 11 will be too long, potentially causing installation difficulties in applications with tight space requirements.

[0082] In some embodiments, optionally, the length of the expanding section 112 along the direction from one end of the catheter 12 to the other end of the catheter 12 is 1 mm.

[0083] In some embodiments, optionally, the length of the expanding section 112 along the direction from one end of the catheter 12 to the other end of the catheter 12 is 2 mm.

[0084] In some embodiments, optionally, the length of the expanding section 112 along the direction from one end of the catheter 12 to the other end of the catheter 12 is 3 mm.

[0085] In some embodiments, the length of the expanding section 112 is optionally 4 mm along the direction from one end of the catheter 12 to the other end of the catheter 12.

[0086] In some embodiments, the length of the expanding section 112 is optionally 5 mm along the direction from one end of the catheter 12 to the other end of the catheter 12.

[0087] In some embodiments, optionally, such as Figure 5 As shown, the conduit 12 is a tapered tube 128, and the cross-sectional area of ​​the conduit 12 gradually decreases from one end to the other.

[0088] In these embodiments, the conduit 12 can also be configured as a tapered tube 128, with the thicker end of the tapered tube 128 positioned within the installation channel 116. This causes the installation gap 13 between the conduit 12 and the installation channel 116 to gradually increase along the direction from one end of the conduit 12 to the other. This allows for the installation of connecting structures or connectors within the larger installation gap 13. Even if the conduit 12 deviates to one side, it provides sufficient space for the placement of the welding strip or solder, thereby effectively improving the welding strength, enhancing the pressure resistance of the reservoir, and ensuring the stability and reliability of the reservoir during use.

[0089] In some embodiments, optionally, such asFigure 6 As shown, the conduit 12 includes a first tube segment 122 and a second tube segment 124, the first tube segment 122 has a larger outer diameter than the second tube segment 124, the first tube segment 122 is arranged near one end of the conduit 12, and the second tube segment 124 is arranged away from the other end of the conduit 12. The first tube segment 122 is arranged in the installation channel 116, and at least part of the second tube segment 124 is arranged in the installation channel 116.

[0090] In some embodiments, the conduit 12 can be arranged in the form of a first tube segment 122 and a second tube segment 124. The first tube segment 122 has a larger outer diameter than the second tube segment 124, the first tube segment 122 is arranged near one end of the conduit 12, and the second tube segment 124 is arranged away from the other end of the conduit 12. The first tube segment 122 is arranged in the installation channel 116, and at least part of the second tube segment 124 is arranged in the installation channel 116.
