[Embodiment 1]
1 is a perspective explanatory view of a machine room base plate and a compressor of a refrigerator according to Embodiment 1 of the present invention, FIG. 2 is a perspective view of the machine room base plate of FIG. 1, and FIG. 3 shows a main part of the refrigerator body. It is a rear view.
As shown in FIG. 3, a machine room base plate 3 made of a metal plate-like member formed by pressing is installed at the bottom of the machine room 2 at the lower back side of the refrigerator body 1, and this machine A compressor 20 is mounted on the chamber base plate 3. And this machine room base plate 3 is directly in contact with the floor surface by the rear legs 4 of the refrigerator main body 1 formed to project downward on the left and right.

The compressor 20 is provided with a discharge pipe 21 on one side (right side as viewed from the back side) through which the compressed refrigerant is sent to the refrigerant circuit, and on the other side (left side) the refrigerant circulating in the refrigerant circuit is provided. A suction pipe 22 returning to the compressor 20 is provided.
In addition, an electrical component storage unit 24 of the compressor 20 is provided on the suction pipe 22 side of the compressor 20 and is connected to an electrical component storage unit 25 for operation such as an operation board of a refrigerator by wiring. A connection line 26 to the power cord is connected to the electric component storage unit 25 for operation.

  Further, a drain pipe 15 from which drainage drainage after defrosting is discharged from the refrigerator body 1 protrudes above the compressor 20, and the drainage drainage discharged from the drain pipe 15 is provided in an evaporating dish provided in the refrigerator body 1. 16 flows into the inside and is evaporated by the heat of the compressor 20.

As shown in FIG. 1, the machine room base plate 3 is formed with four support portions 8 of the compressor 20 by cutting and raising the compressor 20, and the compressor 20 is fitted with the support portion 8 in the leg rubber 28 for the compressor. Is mounted on the machine room base plate 3 and fixed to the support portion 8 by the compressor fixture 27.
Further, as described above, the compressor 20 is provided with the discharge pipe 21 and the suction pipe 22 and connected to the refrigerant circuit in the refrigerator main body 1, and the suction pipe 22 is bent into a substantially square shape downward. A turn part 23 for bent dewdrop is provided.

  The turn part 23 is generally a U-shaped turn in order to make it easy to specify the location where dew is dropped as described above. However, in the present invention, the electric part storage part 24 of the compressor 20 and the operation part are used. In order to prevent the turn portion from coming into contact with the electrical component storage portion 25, the wiring connecting them, the connection line 26 to the power cord, etc., and to facilitate the assembly work of these electrical components and wiring, the suction pipe 22 The dew-turning portion 23 provided on the side is not U-shaped, but a first bent portion 23a bent in the horizontal direction (compressor 20 side) at approximately 90 °, and the first bent portion The second bent portion 23c is bent upward at approximately 90 ° via a substantially horizontal straight line portion 23b continuous with the portion 23a (hereinafter, the turn portion 23 is formed into a square shape). Called the turn part).

  Further, as shown in FIG. 2, the machine room base plate 3 has a concave and flat bottom surface 7 formed between the front side peripheral wall 5 and the rear side peripheral wall 6, and leg portions 4 at both ends thereof. A recess 4a is formed. Further, four support portions 8 that support the compressor 20 are provided on the bottom surface 7 so as to form a quadrangle, and these support portions 8 and the holes 9 in which the support portions 8 are cut and raised are provided around these support portions 8. For example, a bead 10 (hereinafter referred to as a surrounding bead) having a convex shape and a height of about 1 to 10 mm is provided.

Further, a bead 11 (hereinafter referred to as a horizontal bead) extending in the left-right direction is provided between the peripheral beads 10 before and after the bottom surface 7, and both end portions thereof face the concave portion 4 a forming the leg portion 4. . In addition, although the figure showed the case where the two horizontal beads 11 were provided, one may be sufficient.
When the compressor 20 is mounted on the compressor base plate 3, the square turn portion 23 provided on the suction pipe 22 of the compressor 20 is in the vicinity of one recess 4 a (the left side in the figure) that forms the rear leg 4. And located outside the area surrounded by the four surrounding beads 10.

Next, the operation of the present embodiment configured as described above will be described.
As described above, when a large amount of refrigerant is enclosed in the refrigerant circuit and the temperature becomes lower than the outside air, condensation may occur in the suction pipe 22. The condensed water droplets fall from the rectangular turn portion 23 of the suction pipe 22 and flow on the floor surface 7 along the horizontal beads 11 provided between the front and rear peripheral beads 10 to form the concave portions 4a forming the leg portions 4. It flows in and accumulates, and evaporates due to the outside air or the heat of the compressor 20.

  In such an embodiment, even if a water droplet condensed on the suction pipe 22 falls from the square turn part 23, the square turn part 23 is outside the region surrounded by the four peripheral beads 10, A water droplet does not fall on the floor from the hole 8 after the support portion 8 is cut and raised.

  Further, even when the straight portion 23b of the rectangular turn portion 23 of the suction pipe 22 is inclined rather than horizontal, and the bent portion 23a or 23c of the rectangular turn portion 23 is not near the recess 4a, the rectangular turn portion Since 23 is outside the area surrounded by the surrounding beads 10, the water drops that have fallen from now flow on the floor surface 7 along the horizontal beads 11 and flow into the recesses 4 a, so that the water drops cut the support part 8. It does not fall on the floor from the other hole 9.

  Furthermore, when the natural frequency of the suction pipe 22 is close to the frequency of the power source, the pipe may be damaged due to secular change due to resonance or chatter. In order to prevent the occurrence of such a problem, the suction pipe 22 is usually used. The natural frequency of the suction pipe 22 is changed by changing the shape of 22 or adding leg rubber to be inserted between the compressor 20 and the like.

  In this embodiment, even in such a case, the suction pipe 22 is provided with a square turn portion 23 instead of a U-shape, but the square turn portion 23 is outside the region surrounded by the four peripheral beads 10. In this case, the water drops that have fallen from the square turn part 23 do not fall on the floor from the holes 9 after the support part 8 is cut and raised.

  Further, as described above, drain drainage after defrosting is accumulated in the evaporating dish 16 and evaporates due to the heat of the compressor 20. For example, a large amount of drainage is left in the cooler due to forgetting to close the refrigerator door. When the frost is attached and the drainage becomes larger than usual, it may overflow from the evaporating dish 16 and fall onto the machine room base plate 3. In such a case, drainage drainage collects in the recesses 4a and the bottom surface 7 that form the legs 4, but the periphery of the hole 9 that cuts and raises the support portion 8 of the compressor 20 provided at four locations on the bottom surface 7 is a peripheral bead. Since it is surrounded by 10, the drainage does not flow out of the hole 9 until the door that was forgotten to close is closed.

  In this case, even if the drainage drainage in the evaporating dish 16 is evaporated by the fan wind, the heat of the discharge pipe 21, etc., the drainage draining from the evaporating dish 16 will cause the rear leg 4 of the machine room base plate 3 to flow. The same effect can be obtained as long as it is a structure that accumulates in the recessed portion 4a or the bottom surface 7 to be formed.

  Further, when the evaporating dish 16 is removed for moving or the like and the installation of the evaporating dish 16 is forgotten at the time of installation, the drainage water after defrosting falls on the high-temperature compressor 20 and a juicy sound is generated. You may notice that the pan 16 is not installed, and install it. In addition, because the drain drainage varies depending on how the frost is formed, the drainage drain may fall due to the absence of the user because the evaporating dish 16 is not attached due to the several drain drain drops. In the case where the user does not notice that the evaporating dish 16 is attached, a part of the drainage drains on the machine room base plate 3.

  In such a case, the drain drainage that has fallen collects in the recess 4 a that forms the legs 4 of the machine room base plate 3 and on the concave bottom surface 7, but the hole 9 that cuts and raises the support 8 is a peripheral bead 10. Since it is surrounded, the drainage does not fall from the hole 9 onto the floor.

FIG. 4 is a perspective view of the machine room base plate of the refrigerator according to Embodiment 2 of the present invention.
In Embodiment 1, although the case where the support part 8 of the compressor 20 was provided by cutting up and raising in four places of the machine room base plate 3 was shown, this Embodiment has holes in four places of the machine room base plate 3. the provided 9a, insert the bottom of the stud-like member for mounting the compressor 20 into the hole 9a, for example, it is obtained by constituting the support portions 8a and fixed by spot welding. A peripheral bead 10 is provided around the hole 9a (support portion 8a) as in the case of the first embodiment.

  Also in the present embodiment, when water droplets of dew condensation generated in the suction pipe 22 or drainage drainage generated by defrosting accumulates on the concave portion 4a and the concave bottom surface 7 constituting the leg portion 4 of the machine room base plate 3. Since a peripheral bead 10 is provided around the hole 9a that is welded by inserting the lower portion of the support portion 8a, water droplets or drainage can enter even if there is a gap between the support portion 8a and the hole 9a. And never fall to the floor.
