Description

  The present invention relates to a compressor fixing structure for fixing a compressor to a bottom plate of an outdoor unit of an air conditioner.

  2. Description of the Related Art Conventionally, as a compressor mounted on an outdoor unit of an air conditioner, a hermetic compressor in which an electric element and a rotary compression element that is driven by the electric element and compresses a refrigerant is contained in a hermetic container. . This type of compressor has a plurality of leg pieces at the lower end of the hermetic container, and each leg piece is fixed to the bottom plate of the outdoor unit with a fastener such as a bolt between the leg piece and the bottom plate. An anti-vibration member is interposed. Since this vibration isolating member is formed of an elastic material such as rubber, vibration transmission to the bottom plate is suppressed by absorbing vibration generated in the sealed container during operation of the compressor by the vibration isolating member ( For example, see Patent Document 1).

JP 2009-162120 A

However, when the compressor is started, a large torque is generated in the hermetic container in order to follow this rotation when the rotary compression element starts rotating in the hermetic container. The large torque generated at the time of starting has a problem that a great amount of stress is applied to the fastener by largely deforming the vibration isolating member via the leg piece.
The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a fixing structure for a compressor in which stress generated in a fastener is relieved when the compressor is started.

In order to achieve the above object, the present invention provides a compressor that fixes an electric element in a hermetic container and a rotary compression element that is driven by the electric element and compresses a refrigerant to a bottom plate of an outdoor unit. In the fixing structure, the anti-vibration member is interposed between the leg piece provided in the sealed container and the bottom plate, and the anti-vibration member is a fastener for fastening the leg piece and the bottom plate. A collar member that is harder than the vibration isolator member is disposed in the through hole so as to surround the fastener, and a thread portion of the fastener is loosely fitted in the collar member. A first collar member; and a second collar member having a support portion for inserting the lower end portion of the first collar member and supporting the first collar member, and a female thread portion concentrically engaged with the fastener. The second collar member is fixed to the bottom plate, and the front It said first portion collar member is loosely fitted in the second collar member is characterized by being formed thicker than the base end portion of the second collar member.

Oite to this configuration, the second collar member, and said female thread portion and the support portion may be integrally formed.

Further, in this configuration, when the collar member is placed on the bottom plate, the height from the placement surface of the bottom plate to the top surface of the tip of the collar member is the same as the through hole of the vibration isolation member. They may be formed at substantially the same height. Further, the compressor may be a constant speed compressor in which the electric element rotates at a rotation speed depending on a power supply frequency.

According to the present invention, the anti-vibration member interposed between the leg piece portion and the bottom plate provided in the sealed container is provided, and the anti-vibration member is penetrated by the fastener that fastens the leg piece portion and the bottom plate. A through-hole, a collar member that is harder than the vibration-proof member is disposed in the through-hole so as to surround the fastener, and the collar member is fixed to the bottom plate and screwed into the collar member with the fastener. Since the portion is provided, the fastener and the collar member screwed into the female screw portion are restricted from moving on the bottom plate. For this reason, when a collar member suppresses a deformation | transformation of a vibration proof member, the stress which arises in a fastener at the time of starting of a compressor can be relieved. Further, by dividing the first collar member and the second collar member, the second collar member can be made into a simple shape, and the second collar member can be manufactured inexpensively and easily. Furthermore, the strength of the support portion of the second color member can be improved by forming the support portion of the second collar member thicker than the first color member, and the color member is caused by the shear stress received from the leg piece portion. Since the distortion of the collar member due to the bending moment acting on the whole can be suppressed to a low level, and therefore deformation of the mount rubber can be further suppressed, the stress generated on the bolt when the compressor is started can be reduced.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, the code | symbol 2 shows the outdoor unit of an air conditioning apparatus. The outdoor unit 2 includes a fixed capacity (constant speed) compressor 11 and a four-way valve 15 on a bottom plate 10, and further, an accumulator, an oil separator, an outdoor heat exchanger, an outdoor unit, not shown. An expansion valve, a receiver tank, and the like are provided, and these components are roughly configured by pipe connection. The outdoor unit 2 is connected to the indoor unit by a gas pipe and a liquid pipe (not shown).
The compressor 11 is a hermetic scroll compressor, and includes a hermetic container 61, an electric element (not shown) that is housed in the hermetic container 61 and driven at a substantially constant rotational speed depending on the power frequency, A rotary compression element (not shown) that is driven by the electric element to compress the refrigerant. The sealed container 61 is a cylindrical container that is long in the height direction, and a plurality of leg pieces 62 extending radially are provided at the lower portion of the sealed container 61.
In addition, a refrigerant discharge pipe 32 that discharges the refrigerant compressed by the rotary compression element is connected to the upper part of the sealed container 61, and a refrigerant suction pipe that guides the refrigerant into the sealed container 61 is connected to the lower part of the sealed container 61 ( (Not shown) and an oil pipe 37 for adjusting the amount of oil in the sealed container 61 are connected.

  The bottom plate 10 is formed by bending a sheet metal by pressing or the like, and a reinforcing plate that reinforces the bottom plate 10 on the bottom plate 10 at a place where each leg piece 62 of the compressor 11 is fixed. A bottom plate 72 is attached. In this specification, the “bottom plate” includes a state in which the reinforcing plate 72 is attached on the bottom plate 10 in addition to the above-described bottom plate 10. The reinforcing plate 72 is a plate material formed thicker than the thickness of the bottom plate 10. The rigidity of the bottom plate 10 is increased to suppress vibration during operation of the compressor 11, and the bottom plate 10 when the compressor 11 is fixed. The fastening strength is increased.

The compressor 11 is fixed to a reinforcing plate 72 attached on the bottom plate 10. Specifically, as shown in FIG. 2, a mount rubber (vibration isolation member) 63 is interposed between each leg piece 62 of the compressor 11 and the reinforcing plate 72. The mount rubber 63 is penetrated from above with a bolt 65 with a flat washer 64, and the bolt 65 is fastened to the reinforcing plate 72.
The mount rubber 63 has a function of absorbing vibration generated during operation of the compressor 11 and suppressing transmission to the bottom plate 10 and the reinforcing plate 72.
However, when the constant speed compressor 11 is started, the rotary compression element suddenly starts rotating in the sealed container 61, so that a large torque is generated in the sealed container 61 in order to follow this sudden rotation. To do. The large torque generated at the time of starting has a problem that a great stress is applied to the bolt 65 that fastens the leg piece 62 and the reinforcing plate 72 by greatly deforming the mount rubber 63 via the leg piece 62. When the hardness of the mount rubber 63 is increased, it is possible to reduce the stress applied to the bolt 65, but the function of suppressing the vibration generated during the operation of the compressor 11 is reduced, and the bottom plate 10 and the reinforcing plate 72 vibrate. It becomes. For this reason, this configuration is characterized by a fixing structure that relaxes stress concentration on the bolt 65 without increasing the hardness of the mount rubber 63.

FIG. 3 is a side cross-sectional view showing a compressor fixing structure according to the present embodiment.
In the compressor fixing structure of this configuration, the collar member 70 is disposed inside the mount rubber 63 so as to surround the bolt 65, and the collar member 70 is fixed to the reinforcing plate 72, so that the compressor 11 is started up. While suppressing the deformation | transformation of the said mounting rubber 63 accompanying the rotational torque which acts on the airtight container 61, the stress concentration to the said volt | bolt 65 is eased.

  As shown in FIG. 3, the leg piece portion 62 includes an upper surface portion 62A and a side surface portion 62B extending downward from the edge portion of the upper surface portion 62A. The side surface portion 62B and the upper end portion of the mount rubber 63 are side surfaces. It overlaps visually. As a result, the mount rubber 63 moves following the operation of the sealed container 61 and the leg piece 62, absorbs the vibration of the sealed container 61, and suppresses the vibration from being transmitted to the reinforcing plate 72 and the bottom plate 10. To do.

The mount rubber 63 includes a through hole 63 </ b> A that accommodates the collar member 70 in the mount rubber 63. The through hole 63A penetrates substantially the center of the mount rubber 63 in the vertical direction, and has a shape similar to that of the collar member 70 described later, that is, a shape in which the lower part of the through hole 63A has a diameter larger than the upper part in a stepped manner. ing.
On the upper surface 63C of the mount rubber 63, a neck portion 63B protruding upward from the upper surface 63C is formed around the through hole 63A. As shown in FIG. 3, when the leg piece 62 is placed on the upper surface 63C of the mount rubber 63, the neck 63B penetrates the opening 62C formed in the upper face portion 62A of the leg piece 62, and the leg 63B It protrudes above the piece 62. As a result, the neck portion 63B of the mount rubber 63 extends between the bolt 65 and the collar member 70 arranged in the through hole 63A and the edge portion of the opening 62C of the leg piece portion 62. Even when the leg piece 62 swings, contact between the leg piece 62 and the bolt 65 (collar member 70) is prevented, and an excessive shearing force is prevented from acting on the bolt 65.
Further, an O-ring 71 is disposed around the neck portion 63B of the neck portion 63B of the portion protruding from the opening 62C of the leg piece portion 62. The O-ring 71 is provided between the flat washer 64 and the upper surface portion 62A of the leg piece portion 62. Even if an upward force is applied to the leg piece portion 62 during transportation, the O-ring 71 is made of a metal leg piece portion. 62 and the flat washer 64 are prevented from coming into direct contact. By disposing the O-ring 71, it is possible to prevent a large impact load from being applied to the leg piece portion 62 and to relieve stress applied to the leg piece portion 62 or the bolt 65.

The collar member 70 is formed of a metal such as an iron material harder than the mount rubber 63. As shown in FIG. 3, the collar member 70 has a first collar member (tip portion) 73 formed in a cylindrical shape, and the first collar member 73. And a second collar member 74 that is inserted into the lower end 73B and supports the first collar member 73. The first collar member 73 is a pipe member having a hole portion 73A formed to have a diameter slightly larger than the diameter of the screw portion 65A of the bolt 65, and the screw portion 65A of the bolt 65 is loosely fitted in the hole portion 73A. The
The second collar member 74 is screwed into a support portion (base end portion) 75 that supports the first collar member 73 and a screw portion 65A of the bolt 65 that passes through the hole 73A of the first collar member 73. The female screw portion 76 is integrally provided, and the female screw portion 76 extends to the lower surface side of the reinforcing plate 72 through the opening 72 </ b> A formed in the reinforcing plate 72 and is welded to the reinforcing plate 72.

As shown in FIG. 4, the second collar member 74 has a shape in which large and small diameter pipes are concentrically joined up and down, and the inner peripheral surface 75A of the support portion 75 formed to have a large diameter includes: The lower end 73B (FIG. 3) of the first collar member 73 is inserted and fitted. In addition, a screw 76B that is screwed with the screw portion 65A of the bolt 65 (FIG. 3) is formed on the inner peripheral surface 76A of the female screw portion 76 that has a small diameter.
In this configuration, since the inner diameter of the inner peripheral surface 76A of the female thread portion 76 is formed substantially the same as the inner diameter of the hole portion 73A of the first collar member 73, the bolt 65 inserted into the hole portion 73A can be easily attached. The internal thread portion 76 can be screwed together.

Between the inner peripheral surface 75A of the support portion 75 and the inner peripheral surface 76A of the female screw portion 76, a contact surface 76C that decreases in a step shape and contacts the lower end surface 73B1 (FIG. 3) of the first collar member 73. Is formed. The contact surface 76 </ b> C contacts the lower end surface 73 </ b> B <b> 1 of the first collar member 73, thereby restricting the downward movement of the first collar member 73.
The outer diameter of the female screw portion 76 is formed to fit into an opening 72A formed in the reinforcing plate 72, and a stepped shape is formed between the outer peripheral surface 76D of the female screw portion 76 and the outer peripheral surface 75B of the support portion 75. A contact surface 75C that expands in diameter and contacts the upper surface of the reinforcing plate 72 is formed. In this embodiment, by fitting the female thread portion 76 of the second collar member 74 into the opening 72A of the reinforcement plate 72 from above, the contact surface 75C of the second collar member 74 contacts the reinforcement plate 72, and the female thread portion 76 is held in a state of being positioned on the lower surface side of the reinforcing plate 72. For this reason, the second collar member 74 is fixed to the reinforcing plate 72 by welding the outer peripheral surface 76D of the female screw portion 76 and the reinforcing plate 72 in this state.
In this case, as shown in FIG. 3, the bottom plate 10 has an opening 10 </ b> A that is sufficiently larger than the outer diameter of the female threaded portion 76 of the second collar member 74, and is reinforced by welding the second collar member 74. The plate 72 can be easily attached to the bottom plate 10 from above the bottom plate 10.

  In this configuration, the collar member 70 (the first collar member 73 and the second collar member 74) is disposed in the through hole 63A in the mount rubber 63, so that the collar member 70 serves as a shaft member of the mount rubber 63. Therefore, deformation of the mount rubber 63 in the horizontal direction (shear direction) is suppressed. This prevents horizontal stress from concentrating on the bolts 65 that are loosely fitted into the holes 73 </ b> A of the collar member 70. Furthermore, since the second collar member 74 constituting the collar member 70 is welded to the reinforcing plate 72, the mounting rubber 63 that accommodates the collar member 70 is restricted from sliding on the reinforcing plate 72. For this reason, when the collar member 70 suppresses the deformation of the mount rubber 63, the stress generated in the bolt 65 when the compressor 11 is started can be relaxed.

Further, in this configuration, since the second collar member 74 includes the female thread portion 76 that is screwed into the bolt 65, when the second collar member 74 is welded to the reinforcing plate 72, the second collar member 74 causes the female thread portion 76 to be welded. The position when the mount rubber 63, the first collar member 73, and the bolt are arranged on the second collar member 74 can be easily aligned, and the compressor 11 can be attached to the reinforcing plate 72. The fixing work can be facilitated.
Further, in this configuration, the collar member 70 is configured by dividing the first collar member 73 into the second collar member 74 so as to be freely inserted, and therefore when the second collar member 74 is welded to the reinforcing plate 72. The unevenness of the reinforcing plate 72 can be suppressed, and the handling of the reinforcing plate 72 becomes easy. In addition, since an existing pipe can be used as the first collar member 73, the second collar member 74 can have a simple shape, and the second collar member 74 can be manufactured inexpensively and easily. Can do.

  In addition, the collar member 70 includes a first collar member (tip portion) 73 in which a support portion (base end portion) 75 of the second collar member 74 located on the reinforcing plate 72 side is located on the leg piece portion 62 side of the sealed container 61. It is formed in a convex shape having a larger diameter than that. In this configuration, since the leg piece portion 62 is placed on the upper surface 63C of the mount rubber 63, when the leg piece portion 62 swings in the horizontal direction when the compressor 11 is started, the collar member 70 is A large bending moment acts on the support portion 75 of the second collar member 74 away from the leg piece portion 62. For this reason, the collar member 70 is received from the leg piece portion 62 because the strength of the support portion 75 is increased by forming the support portion 75 on the reinforcing plate 72 side thicker than the first collar member 73 as described above. The distortion of the collar member 70 due to the bending moment acting on the entire collar member 70 can be suppressed by the shear stress. As a result, the deformation of the mount rubber 63 can be further suppressed, so that the stress generated in the bolt 65 when the compressor 11 is started can be relaxed.

  Further, in this configuration, the collar member 70 has an upper end portion of the first collar member 73 from the contact surface 75C of the second collar member 74 that contacts the placement surface of the reinforcement plate 72 when placed on the reinforcement plate 72. The height of the upper surface 73C1 of 73C is formed substantially the same as the height of the mount rubber 63, and the height position from the lower neck of the bolt 65 to the reinforcing plate 72 is determined by the collar member 70. As a result, when the mount rubber 63 is fastened to the reinforcing plate 72 (bottom plate 10) with the bolt 65 with the flat washer 64, the collar member 70 regulates the tightening position of the bolt 65. No excessive vertical axial force is applied by tightening 65. Therefore, the flexibility of the mount rubber 63 can be maintained, the vibration generated during the operation of the compressor 11 can be absorbed by the mount rubber 63, and the transmission of vibration to the bottom plate 10 and the reinforcing plate 72 is suppressed. it can.

The ring 71 is disposed, and the bolt 65 with the flat washer 64 is inserted into the hole 73 </ b> A of the first collar member 73 from above the leg piece 62. In this case, the hole portion 73A of the first collar member 73 and the female screw portion 76 of the second collar member 74 are arranged concentrically, so that the bolt 65 can be easily screwed into the female screw portion 76, The fixing work of the compressor 11 can be easily performed. Further, since the tightening amount of the bolt 65 is regulated by the height of the first collar member 73 and the second collar member 74 disposed on the reinforcing plate 72, the compressor 11 can be placed on the floor plate even if not skilled. Can be fixed.

As mentioned above, according to this embodiment, the compressor 11 which fixes the compressor 11 which accommodated the electric element in the airtight container 61, and the rotary compression element which is driven by this electric element and compresses a refrigerant | coolant to the baseplate 10 of the outdoor unit 2 is fixed. 11 includes a mounting rubber 63 interposed between a leg piece portion 62 provided on the sealed container 61 and a reinforcing plate 72 disposed on the bottom plate 10, and the mounting rubber 63 includes a leg piece.

Therefore, the bolt 65 and the collar member 70 screwed into the female screw portion 76 are reinforced. It is restricted to move on 72. For this reason, when the collar member 70 suppresses the deformation of the mount rubber 63, the stress generated in the bolt 65 when the compressor 11 is started can be relaxed.
Furthermore, since the female screw portion 76 is provided in the collar member 70, the bolt 65 inserted into the collar member 70 can be easily stopped by the female screw portion 76, and the compressor 11 can be fixed easily.

  Further, according to the present embodiment, the collar member 70 includes the first collar member 73 into which the threaded portion 65A of the bolt 65 is loosely fitted, and the lower end portion 73B of the first collar member 73 inserted therein. And a second collar member 74 having a support portion 75 for supporting the collar member 73 and a female screw portion 76 concentrically, and the second collar member 74 is fixed to the reinforcing plate 72.
