Description

  The present invention relates to a replacement structure for a compressor mounted in a refrigeration apparatus such as a refrigerator or an air conditioner.

  Conventionally, in a refrigeration apparatus such as a refrigerator or an air conditioner, a compressor is fixed to a bottom plate (a casing bottom base) of a casing of the refrigeration apparatus by a plurality of bolts arranged in parallel to the axial direction and on the outer periphery. For this reason, it is not easy to remove all of the bolts that are arranged in parallel in the axial direction and around the circumference for fixing the compressor during maintenance of the refrigeration apparatus. Thus, in order to facilitate the removal and attachment of the compressor during maintenance, a configuration has been proposed in which a drawer is provided so that the compressor can be pulled out (see, for example, Patent Document 1).

JP 2000-258039 A

  By the way, since the compressor is heavy and vibrates, it is desirable that the portion to which the compressor is fixed has higher rigidity. In order to increase the rigidity, the peripheral edge portion of the bottom plate of the housing is formed with a bent portion having a rising shape. However, in order to avoid interference with the bent portion when the drawer portion is pulled out, it is necessary to arrange the drawer portion at a position higher than the bent portion. Thereby, another structure provided between the bottom plate of the housing and the drawer portion increases, and the rigidity of the fixing portion of the compressor decreases due to the increase in the number of structures. In order to compensate for the decrease in rigidity, it is necessary to ensure rigidity by separately increasing the thickness of the structure or the structure.

  An object of the present invention is a refrigeration apparatus that can simultaneously improve the rigidity and simplify the structure of a portion to which a compressor is fixed.

  The present invention includes a compressor housed in a housing, a compressor base on which the compressor is supported, and a housing bottom base that constitutes a bottom portion of the housing and on which the compressor base is placed. The compressor base includes a support plate that supports the compressor, and a first upright portion that rises at an edge of the support plate, and the housing bottom base includes a bottom plate that supports the compressor base; A second upright portion that rises at a peripheral edge of the bottom plate; and a cutout portion that slides the compressor base out of the housing by cutting out the second upright portion, and the compressor base is disposed in the housing The first upright portion is detachably fixed to the second upright portion cut out by the cutout portion in the state of being housed in the housing.

  Hereinafter, modes for carrying out the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the drawings as appropriate. Note that the refrigeration apparatus 1A is installed, for example, outdoors and is configured to be connected to an indoor showcase via a refrigerant pipe.

(First embodiment)
FIG. 1 is an exploded perspective view showing the refrigeration apparatus according to the first embodiment. In the following description, the front-rear, up-down, left-right directions are based on the front-back, up-down, left-right directions shown in FIG.
As shown in FIG. 1, the refrigeration apparatus 1 </ b> A includes a compressor 3 accommodated in the housing 2 and a compressor base 4 that supports the compressor 3. In addition to the compressor 3, a known condenser, a pressure reducing valve, and the like (not shown) are accommodated in the housing 2.

  The housing 2 includes a housing bottom base 21 disposed on the bottom side of the compressor 3, a side panel 22 disposed on the side surface of the compressor 3, a top plate 23 disposed on the upper surface side of the compressor 3, It has. The frame bottom base 21, the side panel 22, and the top plate 23 are formed by, for example, bending a sheet metal by press molding.

  The housing 2 includes a pair of metal legs 5 and 5 and is configured to extend in the front-rear direction. In addition, the leg part 5 is not limited to what extends in the front-back direction, It may extend in the left-right direction.

  The frame bottom base 21 has a rectangular bottom plate 21a and bent portions 21b, 21c, 21d, and 21e (bent upwardly in the vertical direction at the front, rear, left, and right edges of the bottom plate 21a). A second upright portion). Note that the housing bottom base 21 can increase the rigidity of the housing bottom base 21 by forming the bent portions 21b, 21c, 21d, and 21e at the edges that are substantially the entire circumference of the bottom plate 21a.

  Further, the housing bottom base 21 is formed with a notch 30 in which a part is notched in the bent portion 21b on the front side. The width S1 of the notch 30 is set to a dimension that allows passage of a compressor base 4 to be described later.

  Further, the notch 30 is arranged so as to be positioned right above the one (right side) leg 5. In addition, screw holes 21t into which the screws 6A are screwed are formed in the bent portions 21b corresponding to the left and right ends of the cutout portion 30 (both ends in the extending direction of the bent portion 21b).

  The compressor 3 is of a scroll type, for example, and has a cylindrical case 31. A fixing plate 32 for fixing the compressor 3 to the compressor base 4 is formed at the lower end of the case 31. The fixed plate 32 is formed so as to protrude radially outward from the outer peripheral surface of the case 31 and is fixed to the compressor base 4 at equal intervals in the circumferential direction (every 90 ° in the present embodiment). The compressor 3 is elastically supported by the compressor base 4 through an elastic member 45 such as rubber.

  The compressor base 4 includes a rectangular support plate 41 that supports the compressor 3, a bent portion 42 (first standing portion) that is bent upward in the vertical direction at the front edge portion of the support plate 41, and Is formed by bending a sheet metal by press molding. The width (length in the left-right direction) W1 of the support plate 41 is, for example, formed with a minimum width that can pass through the notch 30 in a state where the support plate 41 is horizontal.

  In this example, the bent portion 42 extends evenly in the left-right direction with respect to the width W1 of the support plate 41, and extended portions 42a and 42a (overlap allowance) are formed to overlap the end portions 21s of the bent portion 21b. Yes. Note that the end portions 21 s are portions located on both sides of the cutout portion 30. Thereby, when the compressor base 4 is accommodated in the housing 2 through the notch 30, the extending portions 42a and 42a come into contact with the outer surfaces of the end portions 21s and 21s of the bent portion 21b.

  Each extension 42a is formed with a screw hole 42b through which the screw 6A is inserted at a position corresponding to the screw hole 21d. The bent portions 42a and 42a are formed at substantially the same height as the bent portions 21b, 21c, 21d and 21e of the housing bottom base 21.

  Bending portions 43, 43 are formed at the right and left edges of the support plate 41 by bending upward at a right angle. Thereby, the rigidity of the part in which the compressor 3 is mounted is improved, and the rigidity at the time of supporting the compressor 3 is improved.

Fig.2 (a) is a perspective view which shows a compressor base, (b) is the sectional view on the AA line of (a).
As shown in FIG. 2A, the support plate 41 of the compressor base 4 is formed with a plurality of circular bulging portions 41a protruding upward. The bulging portion 41 a is formed to have substantially the same diameter as the cylindrical elastic member 45, and is formed at a position corresponding to the fixing position of the fixing plate 32.

  Further, at the position of each bulging portion 41a, the bolt 44 is inserted into the compressor base 4 from the back side, and the screw portion 44a of the bolt 44 is fixed so as to protrude upward in the vertical direction (axial direction). . The number of the bulging portions 41a is not limited to four, and may be three or less or five or more.

  As shown in FIG. 2B, the support plate 41 has a recess 41b on the back side of the bulging portion 41a, and a head 44b of the bolt 44 is accommodated in the recess 41b. The head portion 44b is fixed to the recess portion 41b by welding or the like. Thereby, since it can prevent that the volt | bolt 44 protrudes from the lower surface 41u of the support plate 41, the support plate 41 can be stably slid on the bottom plate 21a (refer FIG. 1).

  A cylindrical elastic member 45 is inserted into the threaded portion 44a of the bolt 44 protruding from the bulging portion 41a, and a fixed plate 32 (see FIG. 1) is attached from above the elastic member 45. A nut 46 is screwed into the threaded portion 44a protruding from the nut. Thus, the compressor 3 (see FIG. 1) is attached to the compressor base 4 while being elastically supported.

  When the compressor 3 is housed in the housing 2, the support plate 41 is inserted through the notch 30 and the support plate 41 is in contact with the bottom plate 21 a when the compressor 3 is attached to the compressor base 4. Slide. The extended portions 42a and 42a of the bent portion 42 abut against the end portions 21s and 21s of the bent portion 21b, whereby the compressor base 4 is positioned on the housing bottom base 21. Then, the screws 6A and 6A are inserted into the screw holes 42b and 42b of the bent portion 42 and screwed into the screw holes 22b and 22b of the bent portion 21b, whereby the compressor base 4 is fixed to the casing bottom base 21.

  When the compressor 3 is inspected and replaced during maintenance, etc., by removing the screws 6A and 6A and pulling out the compressor base 4 to the front side (forward) in the reverse procedure. The support plate 41 of the compressor base 4 is pulled out while sliding on the upper surface of the bottom plate 21a.

  As described above, in the refrigeration apparatus 1A according to the first embodiment, the compressor base 4 includes the support plate 41 that supports the compressor 3, and the bent portion 42 that rises at the edge of the support plate 41. The casing bottom base 21 cuts out the bottom plate 21a that supports the compressor base 4, the bent portions 21b, 21c, 21d, and 21e rising at the peripheral edge of the bottom plate 21a, and a part of the bent portion 21b. And a notch 30 for sliding the base 4 to the outside of the housing 2, and the bending portion 42 is detachably fixed to both end portions 21 s and 21 s of the bending portion 21 b in a state where the compressor 3 is housed in the housing 2. ing. According to this, since the cutout portion 30 is formed by cutting out a portion of the bent portion 21b at a position corresponding to the compressor base 4, a structure for raising the bottom to make the bent portion 21b higher is provided. Therefore, the compressor base 4 (compressor 3) can be slid without replacement, and the compressor 3 can be easily replaced or inspected. In addition, since the compressor 3 can be replaced and inspected quickly, the refrigeration cycle stop time can be shortened.

  By the way, as a countermeasure against vibration of the compressor 3, in order to increase the rigidity of the housing 2, bent portions 21b, 21c, 21d, and 21e are formed on the peripheral edge of the bottom plate 21a. When such a bent portion 21b, 21c, 21d, 21e is formed, when the compressor 3 is made to be a drawer type, the bent portion 21b, 21c, 21d, 21e becomes an obstacle, and the compressor base 4 is pulled out. I can't. For this reason, it is necessary to attach a structure for raising the bottom (sheet metal or the like) on the bottom plate 21a. When such a structure is attached, the number of parts increases, and the compressor 3 is supported via a plurality of parts, so that the rigidity for supporting the compressor 3 is reduced. In addition, a space is created between the bottom plate 21a and the compressor base 4, and vibration and sound problems are likely to occur.

  Therefore, in order to allow the compressor base 4 to be pulled out without providing any other structure, when a part of the bent portion 21b is cut out as described above, the casing 2 (the casing bottom base 21) is formed at the notched portion. The rigidity of the steel will decrease. However, in the present embodiment, by forming the bent portion 42 in the compressor base 4 so as to complement the shape of the notch portion 30, and fixing the bent portion 42 to the bent portion 21b of the housing bottom base 21, The bent portion 21b can be configured as a continuous bent portion. Thereby, since the compressor base 4 can be directly fixed to the housing bottom base 21, the rigidity at the time of supporting the compressor 3 can be improved. In addition, the strength of the support plate 41 is increased by forming the bulging portion 41a (recessed portion 41b), and the compressor 3 is placed on the bulging portion 41a and tightened to thereby serve as a reinforcing member for the support plate 41. Come to fulfill.

  As described above, according to the first embodiment, it is possible to improve the rigidity of the portion to which the compressor 3 is fixed while simplifying the structure.

  Moreover, in 1st Embodiment, the extension parts 42a and 42a which overlap with the bending part 21b are formed in the bending part 42, and these extension parts 42a and 42a connect the edge parts 21s and 21s and the screws 6A and 6A of the bending part 21b. Is fixed through. Thus, by fixing through the screw 6A, the compressor base 4 can be detachably fixed to the housing bottom base 2, so that the bending portion 42 can be securely fixed to the bending portion 21b, and the compressor The base 4 can be pulled out quickly.
