Description

Technology Field

[0001] The present invention relates to a scroll compressor for compressing a fluid such as a refrigerant. Background Technology

[0002] Generally, a compressor refers to a mechanical device used for generating high pressure or transporting high-pressure fluids. Among these, compressors applied to vapor compression refrigeration cycles, such as those found in refrigerators and air conditioners, perform the function of compressing the refrigerant and transferring it to the condenser. These compressors can be classified into reciprocating, rotary, and scroll types depending on the method of compressing the refrigerant.

[0003] The scroll compressor corresponds to the scroll type. The scroll compressor is a compressor that continuously and repeatedly performs the suction, compression, and discharge of refrigerant using compression chambers continuously created between the non-swivel wrap of the non-swivel scroll and the spin wrap of the spin scroll when the spin scroll rotates while the spin scroll is arranged in an interlocking manner within the internal space of a case. In this case, the refrigerant is compressed as it flows along the compression chambers between the non-swivel wrap and the spin wrap toward the center of the non-swivel scroll and the spin scroll. Therefore, the inner side, which is the center of the non-swivel scroll and the spin scroll, is implemented as a high-pressure section where relatively high-pressure refrigerant is located, and the outer side of the high-pressure section is implemented as a low-pressure section where relatively low-pressure refrigerant is located.

[0004] Here, when the rotating scroll and the non-rotating scroll are arranged to interlock, if the rotating scroll comes to a sudden stop while rotating, the high-pressure refrigerant located in the high-pressure section flows back and is recompressed by reverse rotation, thereby instantaneously generating a high differential pressure. This differential pressure acts on the suction part of the rotating scroll, posing a high risk of damaging or breaking the rotating wrap.

[0005] To prevent this, a method of increasing the thickness of the swivel wrap positioned on the suction side of the swivel scroll has been proposed. However, this method has a problem in that stability is reduced as the slope of the curve implementing the swivel wrap changes rapidly due to the increase in the thickness of the swivel wrap.

[0006] As another approach, a method has been proposed to add a support member protruding along the direction in which the swivel wrap extends to the end of the swivel wrap positioned on the suction side of the swivel scroll. In order for this support member to possess a supporting force to prevent damage or breakage of the swivel wrap, the length of the support member must be formed long; however, if the length of the support member is increased, the support member may interfere with the suction side of the non-swivel scroll located on the direction in which the swivel wrap extends. Therefore, the method of adding a support member protruding along the direction in which the swivel wrap extends has a problem in that the supporting force possessed by the support member is weak, making it difficult to prevent damage or breakage of the swivel wrap caused by reverse rotation. Furthermore, the method of adding a support member protruding along the direction in which the swivel wrap extends has a problem in that the work of forming the support member is difficult and manufacturing costs increase, because the support member must be formed with high machining precision so that the non-swivel scroll and the support member do not interfere with each other. The problem to be solved

[0030] It can be formed to satisfy . Here, Ø is the diameter of the curved surface of the curved member, r s is the turning radius of the turning plate portion, and l may be a value obtained by subtracting the radius of the curved surface of the curved surface member from the length in which the first support portion protrudes from the end of the turning wrap.

Accordingly, the present invention can prevent the second support member from interfering with the suction hole of the non-swivel scroll, while also increasing the rigidity of the end of the swivel wrap by extending the length of the structure for providing support to the end of the swivel wrap. Therefore, the present invention can reduce the risk of damage or breakage to the swivel scroll due to reverse rotation when the swivel scroll suddenly stops while the suction, compression, and discharge of the refrigerant are taking place as the swivel scroll rotates.

Accordingly, the present invention can reduce the risk of damage or breakage of the swivel scroll due to reverse rotation while ensuring the stability of the process of compressing and discharging the refrigerant.

[0043] The present invention is implemented so that the increase in the length of the second support member can reduce the effect of interference with the suction hole. Accordingly, the present invention can relax the machining precision of the second support member. Therefore, the present invention can strengthen the support force for the end of the swivel wrap by using the second support member, while also realizing improved ease of operation for forming the second support member and reduced manufacturing costs.

[0044] The present invention can be implemented such that the second support member protrudes from the first support member along a radial direction based on the center of the pivoting plate member. Accordingly, the present invention can be implemented such that the direction in which the second support member extends and the direction in which interference with respect to the suction hole increases are different from each other. Therefore, the present invention can be implemented such that the gap between the second support member and the suction hole does not increase even if the length of the second support member increases. Accordingly, the present invention can increase the rigidity of the end of the pivoting wrap by increasing the length of the second support member, while simultaneously improving the ease and cost-effectiveness of forming the second support member by reducing the impact of the increased length of the second support member on interference with the suction hole.

Compressed refrigerant may be discharged from the interior of the above case (2) through the discharge port (22). The discharge port (22) may be connected to a pipe that delivers refrigerant to the condenser of the refrigeration cycle.

Inside the above case (2), the part connected to the intake port (21) and the part connected to the discharge port (22) may be partitioned by a high-low pressure separator (23). In this case, the portion connected to the suction port (21) inside the case (2) can be implemented as a suction space (231). The portion connected to the discharge port (22) inside the case (2) can be implemented as a discharge space (232). The high-low pressure separator (23) can separate the suction space (231), which is relatively low pressure, from the discharge space (232), which is relatively high pressure. The suction space (231) can be positioned below the high-low pressure separator (23), and the discharge space (232) can be positioned above the high-low pressure separator (23). The high-low pressure separator (23) can be coupled to the case (2) so as to be positioned inside the case (2). An oil storage space (24) for storing oil can be positioned inside the case (2).

The oil storage space (24) can be placed at the bottom (lower part) of the case (2).

[0050] An electric motor (25) may be disposed inside the above case (2). The electric motor (25) may operate the compression unit (4). The electric motor (25) may generate rotational force and, by using the rotational force to rotate a rotating member (250), operate the compression unit (4) to compress the refrigerant. The rotating member (250) may be coupled to the compression unit (4). Accordingly, the rotational force generated by the electric motor (25) may be transmitted to the compression unit (4) through the rotating member (250).

When power is applied to the stator coil (252b) from the external power source, the rotor (251) rotates, thereby rotating the rotating member (250). The rotating member (250) can be rotatably coupled to the case (2). In this case, the upper part of the rotating member (250) is coupled to the compression part (4), and the lower part of the rotating member (250) can be rotatably coupled to the bottom of the case (2) through a bearing (250a).

The main frame (3) may support the compression unit (4). In this case, the main frame (3) may support the pivot scroll (5) and the non-pivot scroll (6) of the compression unit (4). By utilizing the relative rotation between the pivot scroll (5) and the non-pivot scroll (6), the compression unit (4) may compress the refrigerant and discharge the compressed refrigerant. In this case, the pivot scroll (5) may pivot relative to the non-pivot scroll (6), thereby enabling relative rotation between the pivot scroll (5) and the non-pivot scroll (6). The main frame (3) may be placed between the compression unit (4) and the rotor (251).

[0062] Referring to FIGS. 1 to 7, the compression unit (4) may be placed inside the case (2). The compression unit (4) may compress refrigerant. Refrigerant introduced into the suction space (231) through the suction port (21) may be supplied to the compression chamber (40, shown in FIG. 2) of the compression unit (4), compressed, and then discharged through the discharge space (232) via the discharge port (22). The compression unit (4) may be placed below the high-low pressure separator (23). That is, the compression unit (4) may be placed in the suction space (231). The compression unit (4) may discharge the compressed refrigerant into the discharge space (232). The compression unit (4) may be supported by the main frame (3).

[0063] The above compression unit (4) may include the above-mentioned pivot scroll (5) and the above-mentioned non-pivot scroll (6). The above-mentioned pivot scroll (5) may be implemented as a pivot scroll according to the present invention.

[0064] The above-mentioned pivot scroll (5) may be placed inside the case (2). The pivot scroll (5) and the above-mentioned non-pivot scroll (6) may be arranged to be stacked vertically. In this case, the pivot scroll (5) may be placed below the above-mentioned non-pivot scroll (6). Although not illustrated, the pivot scroll (5) may also be placed above the above-mentioned non-pivot scroll (6). The pivot scroll (5) may be coupled to the above-mentioned rotating member (250). Accordingly, the pivot scroll (5) may pivot by the rotational force transmitted through the above-mentioned rotating member (250). In this case, the pivot scroll (5) may be coupled to the above-mentioned rotating member (250) at an eccentric position (5a) spaced apart from the rotation axis (250b) of the above-mentioned rotating member (250). Accordingly, when the rotating member (250) rotates around the rotation axis (250b), the pivot scroll (5) can pivot along a circumference where the distance between the rotation axis (250b) and the eccentric position (5a, illustrated in FIG. 2) is the pivot radius (OR, illustrated in FIG. 2). That is, the pivot scroll (5) can revolutionize around the rotation axis (250b). In this case, an eccentric member (250c) may be formed on the upper part of the rotating member (250). The eccentric member (250c) may be formed in a cylindrical shape centered on the eccentric position (5a). Compared to other parts of the rotating member (250) positioned below the eccentric member (250c), the eccentric member (250c) may be formed to have a smaller diameter. The above-mentioned pivot scroll (5) is coupled to the above-mentioned eccentric member (250c), so that it can orbit around the rotation axis (250b) together with the above-mentioned eccentric member (250c) which orbits around the rotation axis (250b).

[0065] In this case, the electric motor (25) may include the balance weight (254). The balance weight (254) can cause the rotating member (250) to rotate stably around the rotation axis (250b) by applying a load in a direction different from the direction in which the eccentric member (250c) is eccentric. For example, the balance weight (254) may apply a load by protruding in a direction opposite to the direction in which the eccentric member (250c) is eccentric. The balance weight (254) may be coupled to the rotating member (250). Although not illustrated, the balance weight (254) may be coupled to other structures, such as the rotor (251), if it can improve the stability of the rotation of the rotating member (250) by applying a load in a direction different from the direction in which the eccentric member (250c) is eccentric. The balance weight (254) may be placed in the oil pocket portion (313). Meanwhile, the rotary scroll (5) may rotate while its rotation is blocked by the anti-rotation member (255). The anti-rotation member (255) may block the rotation of the rotary scroll (5) by using a locking mechanism, etc. For example, the rotation of the rotary scroll (5) may be blocked by inserting the key protrusion of the anti-rotation member (255) into the key groove of the rotary scroll (5). The anti-rotation member (255) may be coupled to the main frame (3).

[0066] Referring to FIGS. 1 to 11, the rotating scroll (5) may include a rotating plate section (51) and a rotating wrap (52).

[0067] The above-mentioned pivot plate section (51) may be positioned facing the above-mentioned non-pivoting scroll (6). For example, the above-mentioned pivot plate section (51) may be positioned below the above-mentioned non-pivoting scroll (6). The above-mentioned pivot plate section (51) may be formed in the shape of a disc overall. The above-mentioned pivot wrap (52) may be coupled to the above-mentioned pivot plate section (51). The above-mentioned pivot plate section (51) may also be coupled to the above-mentioned pivot plate section (51). In this case, the above-mentioned pivot plate section (51) may be positioned between the above-mentioned pivot wrap (52) and the above-mentioned pivot coupling section (5b). The above-mentioned pivot coupling section (5b) may be coupled to the above-mentioned rotating member (250). In this case, the rotational member (250) can be coupled to the rotational shaft coupling part (5b) by inserting the eccentric member (250c) into the inner side of the rotational shaft coupling part (5b). Through the rotational shaft coupling part (5b), the rotational scroll (5) can rotate using the rotational force transmitted from the rotational member (250). The rotational scroll (5) can be supported on the main frame (3). The rotational scroll (5) can be supported on the main frame (3) so as to be able to rotate and move up and down. The rotational scroll (5) can also be supported on the main frame (3) so as not to be able to rotate and move up and down.

[0068] The above-mentioned pivot wrap (52) may be coupled to the pivot plate section (51). The above-mentioned pivot wrap (52) may protrude from the pivot plate section (51) toward the non-pivot scroll (6). The above-mentioned pivot wrap (52) may be formed by extending from an inner region (51a) to an outer region (51b). The inner region (51a) may be an area including the center (510) of the pivot plate section (51). The outer region (51b) may be an area positioned outside the inner region (51a). The outer region (51b) may be positioned to surround the inner region (51a). The above-mentioned pivot wrap (52) may be formed by extending from the inner region (51a) to the outer region (51b) in a spiral shape from the center (510) of the pivot plate section (51). A pivot groove (50) may be provided on the inside of the pivot wrap (52). The pivot groove (50) may be used as a space for compressing refrigerant. Refrigerant may be introduced into the pivot groove (50) through the end (521) of the pivot wrap (52) located in the outer region (51b). In this case, a suction part for introducing refrigerant may be provided at the end (521) of the pivot wrap (52). The end (521) of the pivot wrap (52) may refer to a part located at the end along the direction in which the pivot wrap (52) extends from the center (510) of the pivot plate section (51) to the inner region (51a) to the outer region (51b). The center (510) of the pivot plate section (51) and the eccentric position (5a) may be placed on the same line.

[0069] The above non-rotating scroll (6) may be placed inside the case (2). The above non-rotating scroll (6) and the above rotating scroll (5) may interlock to form the compression chamber (40). The above non-rotating scroll (6) may be connected to the suction space (231) and the above discharge space (232), respectively. Accordingly, the refrigerant may be introduced into the compression chamber (40) through the above non-rotating scroll (6), compressed, and then discharged into the discharge space (232) through the above non-rotating scroll (6). In this case, the above non-rotating scroll (6) may have an intake hole (6a) through which the refrigerant present in the suction space (231) is introduced. The above non-rotating scroll (6) may have a discharge hole (6b) through which the compressed refrigerant is discharged into the discharge space (232). The above non-rotating scroll (6) may be supported on the main frame (3). When the above-mentioned rotating scroll (5) rotates, the above-mentioned non-rotating scroll (6) may not rotate. The above-mentioned non-rotating scroll (6) may be fixedly coupled to the main frame (3) so as not to rotate and not to move up or down. The above-mentioned non-rotating scroll (6) may be coupled to the main frame (3) so as to be able to move up and down without rotating. The above-mentioned non-rotating scroll (6) may be coupled to the scroll support part (32).

[0070] The above non-rotating scroll (6) may include a non-rotating plate section (61) and a non-rotating wrap (62).

[0071] The above non-rotating plate section (61) may be positioned facing the above-mentioned rotating plate section (51). For example, the above-mentioned non-rotating plate section (61) may be positioned above the above-mentioned rotating plate section (51). The above-mentioned non-rotating plate section (61) may be formed in the shape of a disc overall. The above-mentioned non-rotating plate section (61) may be positioned between the high-low pressure separator (23) and the above-mentioned non-rotating wrap (62). The above-mentioned non-rotating plate section (61) may be coupled to the above-mentioned main frame (3). The above-mentioned non-rotating plate section (61) may be fixedly coupled to the above-mentioned main frame (3), or may be coupled to the above-mentioned main frame (3) so as to be able to move up and down. In this case, the above-mentioned non-rotating plate section (61) may be coupled to the above-mentioned main frame (3) so as not to rotate. The suction hole (6a) and the discharge hole (6b) may be formed in the above non-rotating plate portion (61). The suction hole (6a) and the discharge hole (6b) may each be formed by penetrating the above non-rotating plate portion (61). The suction hole (6a) and the discharge hole (6b) may be positioned at a spaced-apart location from each other.

[0072] The non-rotating wrap (62) may protrude from the non-rotating plate section (61) toward the rotating plate section (51). For example, the non-rotating wrap (62) may protrude from the non-rotating plate section (61) in a spiral shape. The non-rotating wrap (62) may be positioned to interlock with the rotating wrap (52). In this case, the non-rotating wrap (62) may be inserted into the rotating groove (50).

[0073] The above non-rotating scroll (6) may include a non-rotating groove (60). The rotating wrap (52) may be inserted into the non-rotating groove (60). As the non-rotating wrap (62) is inserted into the rotating groove (50) and the rotating wrap (52) is inserted into the non-rotating groove (60), the non-rotating groove (60) and the rotating groove (50) may be implemented as the compression chamber (40). In this case, the space between the inside of the rotating wrap (52) and the outside of the non-rotating wrap (62) may be implemented as the first compression chamber, and the space between the inside of the non-rotating wrap (62) and the outside of the rotating wrap (52) may be implemented as the second compression chamber. As the above-mentioned pivot scroll (5) moves in a pivoting motion, the volumes of the first compression chamber and the second compression chamber change, thereby enabling the suction of the refrigerant, the compression of the refrigerant, and the discharge of the refrigerant. This process can be carried out with the lower end of the non-pivoting wrap (62) in contact with the upper surface of the pivoting plate section (51), and the upper end of the pivoting wrap (52) in contact with the lower surface of the non-pivoting plate section (61). Contact between the non-pivoting wrap (62) and the pivoting plate section (51), and contact between the pivoting wrap (52) and the non-pivoting plate section (61), can be achieved by the upward movement of the pivot scroll (5). Contact between the non-rotating wrap (62) and the rotating plate section (51) and contact between the rotating wrap (52) and the non-rotating plate section (61) may be achieved by the lowering of the non-rotating scroll (6) and the raising of the rotating scroll (5).

[0074] Here, if the rotary scroll (5) suddenly stops while the suction, compression, and discharge of refrigerant are being performed as the rotary scroll (5) rotates, the high-pressure refrigerant located in the inner region (51a) flows back and is re-compressed by reverse rotation, thereby instantaneously generating a high differential pressure, and this differential pressure may damage or break the rotary scroll (5). In order to reduce the risk of damage or breakage of the rotary scroll (5) due to reverse rotation in this way, the rotary scroll (5) in the scroll compressor (1) according to the present invention may include a first support member (53) and a second support member (54).

[0075] Referring to FIGS. 1 to 11, the first support member (53) may protrude along the direction in which the pivoting wrap (52) extends from the end (521) of the pivoting wrap (52) disposed in the outer region (51b). Accordingly, the first support member (53) can increase the rigidity of the end of the pivoting wrap (52) by providing support for the end of the pivoting wrap (52). The first support member (53) and the pivoting wrap (52) may be formed to form a curved surface in which an inner surface facing the pivoting groove (50) and an outer surface opposite to the inner surface are each continuously connected. Accordingly, the first support member (53) can be implemented so as not to come into contact with the non-pivoting wrap (62) while pivoting together with the pivoting scroll (5). The first support member (53) may protrude from the end (521) of the pivoting wrap (52) toward the suction hole (6a) of the non-pivoting scroll (6). In this case, the length (53a, illustrated in FIG. 11) of the first support member (53) protruding from the end (521) of the pivoting wrap (52) may be set to a maximum value up to the position where the first support member (53) contacts the suction hole (6a) without obstructing the suction hole (6a) during the pivoting motion of the first support member (53) as the pivoting scroll (5) moves. That is, the first support member (53) may be formed with a length (53a) that does not interfere with the suction hole (6a) during the pivoting motion. The first support member (53) and the pivoting wrap (52) may be formed integrally. The first support member (53) may be coupled to the rotating plate member (51) so as to protrude toward the non-rotating plate member (61). The first support member (53) and the rotating plate member (51) may be formed integrally. Meanwhile, the first support member (53) may be formed to have a thickness that roughly matches the end (521) of the rotating wrap (52).In this case, the thickness may be a length based on an axial direction perpendicular to the direction in which the first support member (53) protrudes and extends from the end (521) of the pivot wrap (52).

[0076] Referring to FIGS. 1 to 14, the second support member (54) may protrude from the first support member (53) in a direction different from the direction in which the first support member (53) protrudes from the end (521) of the pivot wrap (52). Accordingly, the scroll compressor (1) according to the present invention can prevent the second support member (54) from interfering with the suction hole (6a), while increasing the rigidity of the end (521) of the pivot wrap (52) by extending the length of the structure to provide support for the end (521) of the pivot wrap (52). Therefore, the scroll compressor (1) according to the present invention can reduce the risk of damage or breakage of the pivot scroll (5) due to reverse rotation when the pivot scroll (5) suddenly stops while the suction, compression, and discharge of the refrigerant are performed as the pivot scroll (5) moves. In addition, the scroll compressor (1) according to the present invention can increase the rigidity of the end (521) of the swivel wrap (52) without increasing the thickness of the end (521) of the swivel wrap (52), thereby ensuring the stability of the process of compressing and discharging the refrigerant while reducing the risk of damage or breakage of the swivel scroll (5) due to reverse rotation. Furthermore, the scroll compressor (1) according to the present invention can reduce the effect of the increase in the length of the second support member (54) on interference with the suction hole (6a), thereby relaxing the machining precision of the second support member (54). Accordingly, the scroll compressor (1) according to the present invention can strengthen the support force of the end (521) of the swivel wrap (52) using the second support member (54), while also realizing improved ease of operation for forming the second support member (54) and reduced manufacturing costs. The second support member (54) and the first support member (53) may be formed integrally. The second support member (54) may be coupled to the rotating mirror plate member (51) so as to protrude toward the non-rotating mirror plate member (61).The second support member (54) and the pivot plate member (51) may be formed integrally. Meanwhile, the second support member (54) may be formed to have a thickness (54b) that is approximately the same as that of the first support member (53). In this case, the thickness (54b) of the second support member (54) may be a length based on an axis direction perpendicular to the direction in which the second support member (54) protrudes and extends from the first support member (53). The second support member (54) may be coupled to the end of the first support member (53).

[0077] As illustrated in FIG. 11, the second support member (54) may protrude from the first support member (53) along a radial direction (511) based on the center (510) of the pivot plate member (51). Accordingly, the direction in which the second support member (54) extends and the direction in which interference with respect to the suction hole (6a) increases may be implemented differently. Thus, even if the length (54a) of the second support member (54) increases, the gap between the second support member (54) and the suction hole (6a) may not increase. Accordingly, the scroll compressor (1) according to the present invention can increase the rigidity of the end (521) of the swivel wrap (52) by increasing the length of the second support member (54), while also improving the ease and cost-effectiveness of forming the second support member (54) by reducing the effect of the increased length of the second support member (54) on interference with the suction hole (6a). In this case, the direction in which interference with the suction hole (6a) increases may refer to the direction in which the first support member (53) protrudes and extends from the end (521) of the swivel wrap (52). Meanwhile, the radial direction (511) may be any one of a plurality of radial directions extending radially with respect to the center (510) of the swivel plate member (51).

[0078] As illustrated in FIGS. 12 and 13, the second support member (54) may protrude from the first support member (53) at an angle with respect to the radial direction (511) with respect to the center (510) of the pivot plate member (51). For example, as illustrated in FIG. 12, the second support member (54) may protrude from the first support member (53) such that the included angle (540) positioned between it and the first support member (53) forms an acute angle. In this case, the second support member (54) may be implemented such that its length (54a, illustrated in FIG. 11) increases in the direction in which the distance from the suction hole (6a) increases. Accordingly, even if the length (54a) of the second support member (54) increases, the distance between the second support member (54) and the suction hole (6a) may not increase. For example, as illustrated in FIG. 13, the second support member (54) may protrude from the first support member (53) such that the interlocking angle (540) positioned between it and the first support member (53) forms an obtuse angle. In this case, the second support member (54) is implemented such that its length (54a) increases in the direction in which the distance from the suction hole (6a) decreases, but the rate of decrease in the distance from the suction hole (6a) can be lowered relative to the rate of increase in length of the second support member (54) when compared to the rate of increase in length of the first support member (53). Thus, the scroll compressor (1) according to the present invention is implemented so that even if the length (54a) of the second support member (54) increases, the effect on interference with the suction hole (6a) can be reduced. Accordingly, the scroll compressor (1) according to the present invention can increase the rigidity of the end (521) of the swivel wrap (52) by using the second support member (54), while also improving the ease and cost-effectiveness of the work of forming the second support member (54).

[0079] Referring to FIGS. 1 to 14, the second support member (54) may include a curved member (541). The curved member (541) may correspond to the end portion of the second support member (54) facing the direction of protrusion from the first support member (53). The curved member (541) may be formed such that the end portion (541a) facing the direction of protrusion from the first support member (53) forms a curved surface. Accordingly, when compared to a comparative example in which the end portion of the second support member (54) is formed in a rectangular shape, the scroll compressor (1) according to the present invention is implemented so as to reduce the size of the avoidance space that must be secured in the non-rotating scroll (6) to prevent the second support member (54) from coming into contact with the non-rotating scroll (6) while rotating, by utilizing the curved member (541). In addition, the scroll compressor (1) according to the present invention can reduce the degree of damage or breakage to the non-rotating scroll (6) by using the curved surface member (541) even if the end portion of the second support member (54) comes into contact with or collides with the non-rotating scroll (6) due to reverse rotation. The curved surface member (541) may be formed to have a semicircular cross-section and protrude from the rotating plate portion (51) toward the non-rotating plate portion (61).

[0080] The above curved member (541) can be formed to satisfy the following mathematical formula 1.

[0081]

[0082] In the above mathematical formula 1, Ø may be the diameter of the curved surface of the curved member (541). In this case, the diameter of the curved surface of the curved member (541) may be implemented to be the same as the thickness (54b) of the second support member (54). r sl may be the turning radius (OR). l may be the value obtained by subtracting the radius of the curve of the curved surface member (541) from the length (53a) protruding from the end (521) of the turning wrap (52) of the first support member (53). In the above Equation 1, the left side relates to the size of the avoidance space that must be secured in the non-turning scroll (6) to prevent the second support member (54) from coming into contact with the non-turning scroll (6) while turning. If the left side of the above Equation 1 is larger than the right side, the size of the avoidance space that must be secured in the non-turning scroll (6) increases excessively, and the stroke volume required to compress the refrigerant in the non-turning scroll (6) may decrease. As a result, the compression efficiency of the refrigerant may decrease. To prevent this, the scroll compressor (1) according to the present invention is formed such that the curved member (541) satisfies Equation 1, thereby preventing damage or breakage of the swivel wrap (52) using the second support member (54), while ensuring the stroke volume required to compress the refrigerant in the non-swivel scroll (6), thereby improving the compression efficiency of the refrigerant. Equation 1 can be appropriately applied to an embodiment in which the second support member (54) is implemented solely by the curved member (541), as shown in FIG. 14.

[0083] The length (54a) of the second support member (54) protruding from the first support member (53) may be formed to be equal to or smaller than the calculated value obtained by subtracting half the thickness (54b) of the second support member (54) and the turning radius (OR) from the length (53a) of the first support member (53) protruding from the end (521) of the turning wrap (52). If the length (54a) of the second support member (54) protruding from the first support member (53) is greater than the calculated value, the size of the avoidance space required to be secured in the non-turning scroll (6) increases excessively, and consequently, the stroke volume required to compress the refrigerant in the non-turning scroll (6) may decrease. As a result, the compression efficiency of the refrigerant may be reduced. To prevent this, the scroll compressor (1) according to the present invention is formed such that the length (54a) of the second support member (54) protruding from the first support member (53) is equal to or smaller than the calculated value, thereby preventing damage or breakage of the swivel wrap (52) by using the second support member (54), while ensuring the stroke volume required to compress the refrigerant in the non-swivel scroll (6), thereby improving the compression efficiency of the refrigerant.

[0084] In this case, the second support member (54) may include a connecting member (542). When the second support member (54) includes the curved member (541), the connecting member (542) may be positioned between the curved member (541) and the first support member (53). The second support member (54) may be implemented by the connecting member (542) protruding from the first support member (53) and the curved member (541) protruding from the connecting member (542). That is, the sum of the length (542a) of the connecting member (542) and the radius of the curved member (541) may correspond to the length (54a) of the second support member (54) protruding from the first support member (53). In this case, the thickness (54b) of the second support member (54) can be formed to be the same as the diameter of the curved member (541).

[0085] Referring to FIGS. 1 to 15, the second support member (54) and the first support member (53) may protrude from the pivoting plate member (51) at a height lower than that of the pivoting wrap (52). Accordingly, the scroll compressor (1) according to the present invention can reduce the risk of damage or breakage of the second support member (54) and the first support member (53) due to reverse rotation, and can perform a process of compressing and discharging refrigerant according to preset specifications. This is explained in detail as follows.

[0086] First, in the case of a comparative example where the second support member (54) and the first support member (53) are formed at the same height as the swivel wrap (52), the rigidity of the end (521) of the swivel wrap (52) can be increased, but the rigidity of the upper part of the second support member (54) and the upper part of the first support member (53) may be weakened. Accordingly, there is a risk that the upper part of the second support member (54) and the upper part of the first support member (53) may be damaged or broken due to reverse rotation. In addition, as the space between the first support member (53) and the swivel wrap (52) functions as the compression chamber (40), the refrigerant may be compressed differently from the preset specifications.

[0087] In contrast, the scroll compressor (1) according to the present invention is implemented such that the second support member (54) and the first support member (53) are formed at a lower height than the swivel wrap (52), thereby increasing the rigidity of the end (521) of the swivel wrap (52) while simultaneously preventing the rigidity of the upper part of the second support member (54) and the upper part of the first support member (53) from being weakened. Accordingly, the scroll compressor (1) according to the present invention can reduce the risk of damage or breakage of the swivel wrap (52), the second support member (54), and the first support member (53) due to reverse rotation. Furthermore, since the space between the first support member (53) and the swivel wrap (52) does not function as the compression chamber (40), the scroll compressor (1) according to the present invention can be implemented so that the refrigerant is compressed according to preset specifications. Therefore, the scroll compressor (1) according to the present invention can improve the reliability of the product's performance. For example, when the height of the swivel wrap (52) is defined as 1, the height of the second support member (54) and the first support member (53) may be formed to be 0.5 or more and less than 1. If the height of the second support member (54) and the first support member (53) is formed to be less than 0.5, the supporting force of the second support member (54) and the first support member (53) supporting the end (521) of the swivel wrap (52) is weak, making it difficult to prevent damage or breakage of the swivel wrap (52) due to reverse rotation. Taking this into consideration, the second support member (54) and the first support member (53) may be formed to have a height of 0.5 or more.

[0088] Referring to FIGS. 1 to 16, the rotating scroll (5) may include a third support member (55).

[0089] The third support member (55) may protrude from the pivot wrap (52) at a position spaced apart from the first support member (53). Accordingly, the third support member (55) and the first support member (53) can increase the rigidity of different parts of the pivot wrap (52). The third support member (55) may be coupled to the pivot plate member (51). The third support member (55), the pivot plate member (51), and the pivot wrap (52) may be formed integrally.

[0090] The third support member (55) may protrude from the swivel wrap (52) on a virtual reference line (SL, shown in FIG. 16) connecting the end (521) of the swivel wrap (52) to which the first support member (53) is attached and the center (510) of the swivel plate member (51). That is, with respect to the center (510) of the swivel plate member (51), the end (521) of the swivel wrap (52) and the third support member (55) may be arranged to form an angle of 180 degrees. This takes into account that the differential pressure generated as the high-pressure refrigerant is recompressed due to reverse rotation following a sudden stop acts relatively significantly at the end (521) of the swivel wrap (52) and at the part of the swivel wrap (52) on the opposite side that forms an angle of 180 degrees with the end (521) of the swivel wrap (52). Thus, the scroll compressor (1) according to the present invention is implemented using the third support member (55), the first support member (53), and the second support member (54) to further reduce the risk of damage or breakage of the swivel wrap (52) due to reverse rotation. The thickness of the third support member (55) may be formed to be approximately equal to the thickness of the first support member (53). The length of the third support member (55) protruding from the swivel wrap (52) may be formed to be approximately equal to the length of the second support member (54) protruding from the first support member (53).

[0091] The third support member (55) may protrude from the outermost surface (522) of the pivoting wrap (52) toward the peripheral portion (513) of the pivoting plate portion (51). The peripheral portion (513) may be positioned outside the wrap portion (512) of the pivoting plate portion (51). The wrap portion (512) may be a part of the pivoting plate portion (51) where the pivoting wrap (52) is positioned. The pivoting wrap (52) is not positioned in the peripheral portion (513). The outermost surface (522) of the pivoting wrap (52) may be the outer surface of the pivoting wrap (52) positioned toward the peripheral portion (513). The outermost surface (522) of the pivoting wrap (52) may be positioned on the boundary (514) between the wrap portion (512) and the peripheral portion (513). In this way, since the third support member (55) is positioned in the peripheral portion (513), the rigidity of the swivel wrap (52) can be increased without affecting the stroke volume required to compress the refrigerant in the swivel scroll (5).

[0092] The third support member (55) may protrude from the pivoting wrap (52) along the reference line (SL). In this case, the reference line (SL) may be one of the radial directions based on the center (510) of the pivoting plate member (51). The third support member (55) may also protrude from the pivoting wrap (52) at an angle with respect to the reference line (SL).

[0093] The third support member (55) can be formed at the same height as the swivel wrap (52). Accordingly, the third support member (55) can increase the rigidity of the swivel wrap (52) and simultaneously prevent refrigerant from leaking through the space between the swivel wrap (52) and the non-swivel end plate (61). In this case, unlike when increasing the height of the first support member (53) affects the volume of the compression chamber (40), the third support member (55) is placed in the surrounding area (513), so even if the height is increased, it does not affect the volume of the compression chamber (40). Therefore, the scroll compressor (1) according to the present invention can not only realize the reinforcement of rigidity of the swivel wrap (52) and the prevention of refrigerant leakage by forming the third support member (55) at the same height as the swivel wrap (52), but also improve ease of manufacturing.

[0094] Referring to FIGS. 1 to 18, when the rotating scroll (5) includes the second support member (54), the non-rotating scroll (6) can be implemented in a structure capable of accommodating the second support member (54). To this end, the non-rotating scroll (6) may include a first receiving groove (64) formed in the non-rotating side wall (63). Before describing the first receiving groove (64), the non-rotating side wall (63) is described as follows.

[0095] The non-rotating side wall (63) may protrude from the non-rotating plate portion (61) to surround the outer side of the non-rotating groove (60). The non-rotating wrap (62) may be disposed on the inner side of the non-rotating side wall (63). The non-rotating wrap (62) may be formed on the inner side of the non-rotating side wall (63) by extending toward the non-rotating side wall (63) in a spiral shape from the center (610) of the non-rotating plate portion (61). A flange (630) may be attached to the non-rotating side wall (63). The flange (630) may protrude outward from the outer surface of the non-rotating side wall (63). The flange (630) may be attached to the scroll support portion (32) of the main frame (3).

[0096] The first receiving groove (64) may be formed in the non-rotating side wall (63) so as to be in communication with the non-rotating groove (60). The first receiving groove (64) may be implemented as a groove formed to a certain depth from the inner surface of the non-rotating side wall (63) positioned toward the non-rotating groove (60). As the rotating scroll (5) rotates, a second support member (54) that rotates may be selectively inserted into the first receiving groove (64). Accordingly, the scroll compressor (1) according to the present invention can prevent the second support member (54) from contacting or colliding with the non-rotating side wall (63) during the rotational movement process using the first receiving groove (64), thereby making it possible to further increase the rigidity of the rotating wrap (52) by increasing the length of the second support member (54). That is, the first receiving groove (64) can function as an avoidance space to prevent the second support member (54) from coming into contact with the non-rotating scroll (6) while rotating.

[0097] When the first receiving groove (64) is provided, the non-rotating side wall (63) may include a first receiving surface (631) positioned toward the first receiving groove (64). The first receiving surface (631) may be formed to form a curved surface corresponding to the path of rotational movement of the second support member (54). Accordingly, the scroll compressor (1) according to the present invention can reduce the loss of stroke volume for compressing the refrigerant due to the first receiving groove (64) while preventing the second support member (54) from coming into contact with or colliding with the first receiving surface (631) during rotational movement. The first receiving groove (64) may be formed as a convex curved surface in the direction in which the second support member (54) is inserted. In this case, the second support member (54) may include the curved surface member (541). The above curved member (541) may be formed such that the end (541a) positioned toward the first receiving surface (631) forms a curved surface. Accordingly, even if the end of the second support member (54) comes into contact with or collides with the first receiving surface (631) due to deformation caused by reverse rotation, the scroll compressor (1) according to the present invention can reduce the degree of damage or breakage to the rotating scroll (5) and the non-rotating scroll (6) by utilizing the curved surface of the curved member (541) and the curved surface of the first receiving surface (631).

[0098] Referring to FIGS. 1 to 19, when the rotating scroll (5) includes the third support member (55), the non-rotating scroll (6) can be implemented in a structure capable of receiving the third support member (55). To this end, the non-rotating scroll (6) may include a second receiving groove (65).

[0099] The second receiving groove (65) may be formed in the non-rotating side wall (63) so as to be in communication with the non-rotating groove (60). The second receiving groove (65) may be implemented as a groove formed to a certain depth from the inner surface of the non-rotating side wall (63) positioned toward the non-rotating groove (60). As the rotating scroll (5) rotates, a third support member (55) that rotates can be selectively inserted into the second receiving groove (65). Accordingly, the scroll compressor (1) according to the present invention can prevent the third support member (55) from contacting or colliding with the non-rotating side wall (63) during the rotational movement process using the second receiving groove (65), thereby making it possible to further increase the rigidity of the rotating wrap (52) by increasing the length of the third support member (55). That is, the second receiving groove (65) can function as an avoidance space to prevent the third support member (55) from coming into contact with the non-rotating scroll (6) while rotating. The second receiving groove (65) can be placed on the reference line (SL).

[0100] When the second receiving groove (65) is provided, the non-rotating side wall (63) may include a second receiving surface (632) positioned toward the second receiving groove (65). The second receiving surface (632) may be formed to have a curved surface corresponding to the path of rotational movement of the third support member (55). Accordingly, the scroll compressor (1) according to the present invention can reduce the loss of stroke volume for compressing the refrigerant due to the second receiving groove (65) while preventing the third support member (55) from coming into contact with or colliding with the second receiving surface (632) during rotational movement. The second receiving groove (65) may be formed as a convex curved surface in the direction in which the third support member (55) is inserted. In this case, the third support member (55) may be formed such that the end positioned toward the second receiving surface (632) forms a curved surface. Accordingly, even if the end portion of the third support member (55) comes into contact with or collides with the second receiving surface (632) due to deformation caused by reverse rotation, the scroll compressor (1) according to the present invention can reduce the degree of damage or breakage to the rotating scroll (5) and the non-rotating scroll (6) by utilizing the curved surface of the third support member (55) and the curved surface of the second receiving surface (632).
