[0006] PROBLEMS TO BE SOLVED BY THE INVENTION
[0007] However, in the past fixing mechanism, at the time of assembly of the compressor, if the band is installed in an imperfect state to the holder, the band is detached from the holder due to vibration at the time of carrying or operation of the compressor, and as a result, it can become a cause of noise due to vibration of the reservoir or detachment due to breakage.
[0008] Therefore, a reservoir fixing mechanism capable of suppressing detachment of a band from a holder, and a compressor provided with the reservoir fixing mechanism are provided.

[0010] The reservoir fixing mechanism of the embodiment is for fixing a reservoir to the side of a compressor main body, and includes a band formed in a long strip shape, and a holder fixed to the compressor main body and fixing the reservoir by holding both end portions of the band disposed along the outer periphery of the reservoir. The holder has a fixing portion fixed to the outer peripheral surface of the compressor main body, a folded-back portion provided at the end portion side of at least one of the holder, extending toward the reservoir side, and folded back toward the compressor main body side, and a recess portion formed by slotting the end portion of the folded-back portion. The ratio (L / D1) of the depth dimension (L) of the recess portion with respect to the width dimension (D1) of the recess portion is set to 0.4 or more. Alternatively, the ratio (L / D2) of the depth dimension (L) of the recess portion with respect to the width dimension (D2) of the end portion is set to 0.3 or more.

[0019] Hereinafter, a plurality of embodiments will be described with reference to the drawings. Figure 1 The compressor 1 shown in FIG. 1 can be used as a component of a refrigeration cycle, for example. The compressor 1 is used in connection with an external device such as an evaporator or a condenser, for example. The compressor 1 sucks refrigerant flowing from the external device, compresses the refrigerant in the compressor 1, and supplies the refrigerant to the external device, for example. The compressor 1 can be constituted by a rotary compressor of a single-cylinder type having one compression chamber in a compressor main body 10, or a double-cylinder type having two compression chambers, or a triple-cylinder type having three compression chambers, for example.
[0020] As shown in FIG. 1, the compressor 1 has the compressor main body 10, a reservoir 20, and a reservoir fixing mechanism 30, for example. Figure 1 As shown, the compressor 1 is provided with a discharge pipe 2, an inflow pipe 3, a suction pipe 4, a compressor main body 10, a reservoir 20, and a reservoir fixing mechanism 30. In addition, in the following description, the reservoir fixing mechanism 30 will be sometimes referred to simply as the fixing mechanism 30. Furthermore, Figure 1 The compressor 1 shown is an example of a rotary compressor of a double-cylinder type. The compressor 1 is disposed and used in a posture shown in FIG. 1, and the up-and-down direction of the paper surface shown in FIG. 1 is set as the up-and-down direction of the compressor 1. Figure 1 Figure 1
[0021] The compressor main body 10 is provided with a hermetic container 11. The hermetic container 11 is, for example, made of metal and has a cylindrical shape as a whole. Although details are not shown, a driving mechanism and a compression mechanism are built in the hermetic container 11, and a refrigerant is filled therein. The driving mechanism is configured to have a motor and a cylinder to actuate the compression mechanism. The compression mechanism is actuated by the driving mechanism to compress the refrigerant in the hermetic container 11 and discharge it to the outside of the hermetic container 11. In this case, the discharge pipe 2 is connected to, for example, the upper portion of the hermetic container 11 and extends upward of the hermetic container 11.
[0022] The reservoir 20 has a function of temporarily storing the refrigerant flowing into the compressor main body 10, accumulating the pressure of the refrigerant, and discharging the pressure as needed. The reservoir 20 is made of metal and has a cylindrical shape as a whole, for example, and is configured to be smaller than the compressor main body 10. The reservoir 20 is fixed to the side surface of the compressor main body 10 in a state of floating from the setting surface 90 of the compressor 1. The inflow pipe 3 is connected to, for example, the upper portion of the reservoir 20 and extends upward of the reservoir 20, and is connected to an unshown external device.
[0023] The reservoir 20 is connected to the compressor main body 10 through the suction pipe 4. The suction pipe 4 extends from the bottom of the reservoir 20 and is connected to a position on the lower side of the outer side surface of the hermetic container 11. When the compressor main body 10 is actuated, the refrigerant in the compressor main body 10 is compressed. Then, the compressed refrigerant is discharged from the discharge pipe 2 to the outside of the compressor main body 10 and supplied to an unshown external device.
[0024] Furthermore, due to the discharge of the refrigerant, the suction pipe 4 side of the compressor main body 10 becomes a negative pressure. Thus, the refrigerant in the reservoir 20 is sucked into the compressor main body 10 through the suction pipe 4, and the refrigerant flowing out from the unshown external device is sucked into the inside of the reservoir 20 from the inflow pipe 3. Then, the refrigerant flowing into the reservoir 20 is adjusted to a certain pressure and supplied to the compressor main body 10.
[0025] The fixing mechanism 30 has the function of detachably installing the liquid reservoir 20 on the side of the compressor body 10, i.e., fixing it. The fixing mechanism 30 fixes the liquid reservoir 20 to the side of the compressor body 10 in a state where it floats from the mounting surface 90, i.e., in a position where the bottom of the liquid reservoir 20 does not contact the mounting surface 90.
[0026] like Figures 2 to 5 As shown, the fixing mechanism 30 includes a clamp 40 and a bracket 50. The clamp 40 is formed, for example, by bending a long strip-shaped component that is longer in one direction. The clamp 40 is formed to bend into a curved shape, for example, with a radius of curvature larger than the outer diameter of the reservoir 20, when no external force is applied to the clamp 40. Furthermore, the clamp 40 is composed of a component that can deform to a certain extent along the outer peripheral surface of the reservoir 20 when the reservoir 20 is installed on the compressor body 10. The clamp 40 can be made of a spring-deformable component, for example, spring steel, or other materials.
[0027] The clamp 40 has a fulcrum portion 41 and a locking portion 42. The fulcrum portion 41 and the locking portion 42 are respectively provided at both ends of the clamp 40. The fulcrum portion 41 is the part that is fixed to the bracket 50 before the locking portion 42 when the liquid reservoir 20 is fixed to the compressor body 10. In addition, the fulcrum portion 41 is the part that becomes the fulcrum of the clamp 40 when the clamp 40 is arranged along the outer peripheral surface of the liquid reservoir 20.
[0028] The fulcrum portion 41 is, for example, formed by bending the top end of one side of the clamp 40 toward the curved inner side of the clamp 40, i.e., the reservoir 20 side, into a mountain shape. The locking portion 42 is the part that is fixed to the bracket 50 after the fulcrum portion 41 when the reservoir 20 is fixed to the compressor body 10. The locking portion 42 is configured to be easier to install and remove relative to the bracket 50 than the fulcrum portion 41. The locking portion 42 is, for example, formed by bending the top end of the clamp 40 opposite to the fulcrum portion 41 toward the curved inner side of the clamp 40, i.e., the reservoir 20 side, into a mountain shape, and then further bending it concavely away from the reservoir 20. Alternatively, either the fulcrum portion 41 or the locking portion 42 can be fixed to the bracket 50 by screws or the like.
[0029] The bracket 50 is fixed to the compressor body 10. Furthermore, the bracket 50 has the function of fixing the liquid reservoir 20 by holding the two ends of the clamp 40 arranged along the outer periphery of the liquid reservoir 20, namely the fulcrum portion 41 and the locking portion 42.
[0030] The support 50 is made of metal such as stainless steel and is formed by bending a long strip of material. In this case, such as Figure 1As shown, the width dimension of the bracket 50 is larger than the width dimension of the clamp 40. Furthermore, the width dimension of the clamp 40 and bracket 50 refers to the dimension perpendicular to the length direction of the clamp 40 and bracket 50, i.e. Figure 1 The dimensions in the vertical direction.
[0031] The bracket 50 has a fixing part 51, a folded-back part 52, and a recess 53. The fixing part 51 is provided in a region spanning the center of the bracket 50 along its length direction, and is fixed to the outer peripheral surface of the compressor body 10, i.e., the outer peripheral surface of the sealed container 11. The fixing part 51 is fixed to the outer peripheral surface of the compressor body 10, for example, by welding.
[0032] A fold-back portion 52 is provided at at least one end of the bracket 50. The fold-back portion 52 corresponds at least to the locking portion 42 of the clamp 40 and is configured to lock the locking portion 42. The fold-back portion 52 is provided in the region from the boundary portion of the fixing portion 51 to the end of the clamp 40. The fold-back portion 52 is formed to extend from the boundary portion of the fixing portion 51 toward the reservoir 20 side and then fold back toward the compressor body 10 side.
[0033] In this embodiment, the fold-back portions 52 are respectively provided at the ends of both sides of the bracket 50. Furthermore, the fold-back portions 52 are configured to accommodate both the fulcrum portion 41 and the locking portion 42 of the clamp 40. In this case, as... Figure 4 and Figure 5 As shown, the support 50 can be formed, for example, into a shape that is centrally symmetrical with respect to the length direction of the support 50.
[0034] The recess 53 is formed by slotting the end of the folded-back portion 52. That is, as shown... Figure 4 As shown, the recess 53 is formed into a notch shape by slotting the two sides of the bracket 50 in the width direction toward the length direction of the bracket 50. Here, if the bottom of the recess 53 is set as the bottom 54, then, relative to the recess 53, the two sides of the clamp 40 in the width direction have protrusions 55 that protrude outward from the bottom 54, which is the bottom of the recess 53, toward the outside of the length direction of the bracket 50.
[0035] In this configuration, the operator can secure the liquid receiver 20 to the compressor body 10 as follows: That is, when the operator secures the liquid receiver 20 to the compressor body 10, as... Figure 3 As shown, firstly, the fulcrum 41 of the clamp 40 is hooked onto one of the folded-back portions 52 of the bracket 50. The operator bends the clamp 40 by using the fulcrum 41 as a fulcrum, and simultaneously winds the clamp 40 around the outer circumference of the reservoir 20.
[0036] Then, as Figure 2As shown, the operator hooks the locking part 42 of the clamp 40 onto the folded-back part 52 of one side of the bracket 50. At this time, the operator positions the locking part 42 inside the recess 53, i.e., inside the protrusion 55. As a result, the locking part 42 is embedded inside the recess 53, thereby restricting the horizontal and vertical movement of the locking part 42. Consequently, the liquid reservoir 20 is fixed to the compressor body 10.
[0037] Furthermore, the operator can remove the liquid receiver 20 from the compressor body 10 by performing the reverse steps described above. That is, when removing the liquid receiver 20 from the compressor body 10, the operator... Figure 2 In this state, holding the periphery of the locking part 42, move the locking part 42 away from the bracket 50 to open the clamp 40. Thus, as... Figure 3 As shown, the locking part 42 disengages from the recess 53. Thus, the locking of the locking part 42 is released, and the reservoir 20 becomes detachable from the compressor body 10.
[0038] Here, the hooking or unhooking operation of the clamp 40's locking portion 42 relative to the folded-back portion 52 of the bracket 50 requires the clamp 40 as a whole to elastically deform around the fulcrum portion 41, thus requiring a relatively large force. Therefore, in this embodiment, the bracket 50 is formed in a symmetrical shape with respect to its center in the longitudinal direction. Accordingly, the operator can hook the fulcrum portion 41 and the locking portion 42 of the clamp 40 onto either of the two folded-back portions 52 of the bracket 50. Therefore, the operator can change the installation orientation of the clamp 40 using their dominant hand.
[0039] That is, in the operation of installing the clamp 40 onto the bracket 50 to fix the liquid reservoir 20 to the compressor body 10, the operator typically approaches from, for example, the side opposite to the compressor body 10 relative to the liquid reservoir 20. Figures 1 to 3 Perform the work on the right side of the paper. In this case, for example if the worker is right-handed, then... Figure 3 As shown, the operator hooks the fulcrum 41 of the clamp 40 onto the left side facing the bracket 50. Figure 3 After folding back the paper at the lower side 52, hook the locking part 42 of the clamp 40 onto the right side facing the bracket 50. Figure 3 The folded-back portion 52 is located on the upper side of the paper surface. In this case, the operator can easily operate the locking portion 42 using their dominant right hand.
[0040] Conversely, for example, if the worker is left-handed, then... Figure 3 Conversely, the operator hooks the fulcrum 41 of the clamp 40 onto the right side facing the bracket 50. Figure 3 After folding back the paper surface at the upper side 52, hook the locking part 42 of the clamp 40 onto the left side facing the bracket 50. Figure 3the paper surface lower side of the return portion 52. In this case, the operator easily operates the locking portion 42 with the left hand as the dominant hand.
[0041] Thus, according to the reservoir fixing mechanism 30 of the present embodiment, the operator easily operates the locking portion 42 with the dominant hand, regardless of being right- or left-handed. As a result, the work using the dominant hand becomes easy, and the work error can be reduced.
[0042] According to the above-described embodiment, the fixing mechanism 30 is used to fix the reservoir 20 to the side of the compressor main body 10. The fixing mechanism 30 is provided with the clamp 40 and the bracket 50. The clamp 40 is formed in a long strip shape. The bracket 50 is fixed to the compressor main body 10. The bracket 50 fixes the reservoir 20 to the compressor main body 10 by holding both end portions of the clamp 40, i.e., the fulcrum portion 41 and the locking portion 42, which are arranged along the outer periphery of the reservoir 20.
[0043] The bracket 50 has a fixed portion 51, a return portion 52, and a recessed portion 53. The fixed portion 51 is a portion fixed to the outer peripheral surface of the compressor main body 10. The return portion 52 is provided on at least one end portion side of the bracket 50 and is formed in a shape extending toward the reservoir 20 side and returning toward the compressor main body 10 side. The recessed portion 53 is formed by slotting the end portion of the return portion 52.
[0044] Here, the principle that the locking portion 42 is disengaged from the recessed portion 53 due to vibration is also described with reference to Figure 6 , in addition, the principle that the locking portion 42 is disengaged from the recessed portion 53 due to vibration is also described with reference to Figure 6 , in addition, the principle that the locking portion 42 is disengaged from the recessed portion 53 due to vibration is also described with reference to Figure 6 , in addition, the principle that the locking portion 42 is disengaged from the recessed portion 53 due to vibration is also described with reference to
[0045] In addition, as shown in Figure 6 , the width direction dimension W of the clamp 40, i.e., the width direction dimension W of the locking portion 42, is set to a dimension slightly smaller than the recessed portion width dimension D1 so that the locking portion 42 easily enters the recessed portion 53, and a dimension at which the locking portion 42 does not greatly shake with respect to the recessed portion 53.
[0046] Here, for example, if the locking portion 42 is shallowly inserted with respect to the recessed portion 53, or the fixing of the clamp 40 with respect to the bracket 50 is imperfect, or the vibration during the transport or operation of the compressor 1 is large, the locking portion 42 is disengaged from the recessed portion 53 due to the vibration, for example, as shown in Figure 6vibration of the locking portion 42. In this case, if the depth dimension L of the recessed portion 53 is small relative to the swing range of the locking portion 42, the locking portion 42 jumps over the protruding portion 55 as shown by the two-dot chain line C. Figure 6
[0047] If the vibration is continued in the state where the locking portion 42 jumps over the protruding portion 55, the locking portion 42 moves downward due to the vibration and the weight of the clamp 40. Further, eventually the locking portion 42 passes over the protruding portion 55 and is released from the recessed portion 53, as a result of which the reservoir 20 can be detached from the compressor main body 10. In this case, if the depth dimension L of the recessed portion 53 is increased, the locking portion 42 is less likely to be released from the recessed portion 53. However, if the depth dimension L of the recessed portion 53 is made excessively large, the clamp 40 needs to be deformed greatly at the time of releasing the locking of the locking portion 42, and the workability is poor.
[0048] Therefore, the present inventors have found, through experiments, an appropriate dimensional relationship of the clamp 40 and the bracket 50. That is, the present inventors have found that, by setting the ratio L / D1 of the recessed portion depth dimension L to the recessed portion width dimension D1 to be 0.4 or more, even if the locking portion 42 vibrates, the locking portion 42 is less likely to jump over the protruding portion 55. Similarly, the present inventors have found that, by setting the ratio L / D2 of the recessed portion depth dimension L to the end portion width dimension D2 to be 0.3 or more, even if the locking portion 42 vibrates, the locking portion 42 is less likely to jump over the protruding portion 55.
[0049] Further, the present inventors have found that, by setting either or both of the ratio L / D1 of the recessed portion depth dimension L to the recessed portion width dimension D1 and the ratio L / D2 of the recessed portion depth dimension L to the end portion width dimension D2 to be 1.0 or less, the locking portion 42 can be released from the recessed portion 53 without deforming the clamp 40 excessively.
[0050] In addition, the recessed portion depth dimension L of the bracket 50 can be set to be, for example, 5 mm or more and 10 mm or less. In this case, if the recessed portion depth dimension L is 5 mm, the recessed portion width dimension D1 is set to be 5 mm or more and 12.5 mm or less, and the end portion width dimension D2 is set to be 5 mm or more and 50 / 3 mm or less. Further, if the recessed portion depth dimension L is 10 mm, the recessed portion width dimension D1 is set to be 10 mm or more and 25 mm or less, and the end portion width dimension D2 is set to be 10 mm or more and 100 / 3 mm or less.
[0051] Further, in the present embodiment, as shown in Figure 3 As shown, the depth dimension Ml of the bend of the fulcrum portion 41 of the clamp 40 and the depth dimension M2 of the bend of the locking portion 42 are set within a range of 0.8 to 1.3 times the recess depth dimension L of the recess 53. Thereby, the holding force in the state where the clamp 40 is installed to the bracket 50 can be sufficiently ensured, and in the case where an insufficient installation state due to an operation error is made, the operator can easily recognize, thereby reducing the operation error at the time of installation operation.
[0052] According to the above-described embodiment, the fixing mechanism 30 is used to fix the liquid reservoir 20 to the side of the compressor main body 10. The fixing mechanism 30 is provided with the clamp 40 formed in a long strip shape and the bracket 50. The bracket 50 is fixed to the compressor main body 10. The bracket 50 fixes the liquid reservoir 20 by holding the both end portions, i.e., the fulcrum portion 41 and the locking portion 42, of the clamp 40 arranged along the outer periphery of the liquid reservoir 20.
[0053] The bracket 50 has a fixing portion 51, a folded-back portion 52, and a recess 53. The fixing portion 51 is fixed to the outer peripheral surface of the compressor main body 10. The folded-back portion 52 is provided at the at least one end portion side of the bracket 50 and is formed in a shape extending to the liquid reservoir 20 side and folded back to the compressor main body 10 side. The recess 53 is formed by slotting the end portion of the folded-back portion 52.
[0054] Also, in the fixing mechanism 30, the ratio L / Dl of the depth dimension L of the recess 53 to the width dimension Dl of the recess 53 is set to 0.4 or more.
[0055] Accordingly, it is possible to suppress the locking portion 42 from jumping over the protrusion 55 in the case where the compressor 1 vibrates due to transportation or operation, and as a result, it is possible to suppress the clamp 40 from coming off the bracket 50. Further, according to this, it is possible to prevent an imperfect assembly state such as a positional deviation at the time of installation operation.
[0056] Further, in the fixing mechanism 30, the ratio L / D2 of the depth dimension L of the recess 53 to the width dimension D2 of the end portion is set to 0.3 or more.
[0057] Thereby, it is also possible to suppress the locking portion 42 from jumping over the protrusion 55 in the case where the compressor 1 vibrates due to transportation or operation, and as a result, it is possible to suppress the clamp 40 from coming off the bracket 50.
[0058] The bracket 50 of the fixing mechanism 30 can also be provided as, for example, a variation as shown in the drawing. Figure 7 Figure 7 The bracket 50A shown in the example of Fig. 1 has a recess 53A. The recess 53A is formed in a trapezoidal shape in which the width dimension thereof becomes smaller toward the central side in the length direction from both ends of the bracket 50A. In this case, if the width dimension Dl of the recess 53A is set as the distance between the two protrusions 55, the width dimension D3 of the bottom portion 54 is set as a dimension smaller than the width dimension Dl of the recess 53A when the bottom of the recess 53A is set as the bottom portion 54.
[0059] According to this configuration, the same advantageous effects as those of the above-described Figures 1 to 6 are obtained. Also, since the edge portions 56 on both sides of the recess 53A are tapered, the worker easily moves the locking portion 42 along the tapered edge portions 56 when the locking portion 42 is inserted into the recess 53A and when the locking portion 42 is removed from the recess 53A. Thus, the workability when the locking portion 42 is inserted into the recess 53A and when the locking portion 42 is removed from the recess 53A is improved.
[0060] The present disclosure is described based on an embodiment, but it should be understood that the present disclosure is not limited to this embodiment or configuration. The present disclosure also includes various modifications or variations within the equivalent scope. In addition, various combinations or schemes, and other combinations or schemes including only one element thereof, more than or less than thereof, also fall within the scope or the range of ideas of the present disclosure.
