TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure of a machine room base fixed to a bottom surface of a refrigerator body for installing a compressor and the like in a machine room at a bottom of the refrigerator.
[0002]
[Prior art]
The machine room table is a table in which a compressor and a fan for radiating the machine room are installed in a machine room located at the bottom of the refrigerator, and is fixed to the bottom surface of the refrigerator body.
[0003]
Conventionally, as shown in FIG. 6, a compressor 101 is installed at a center portion of a machine room base 100 via a support 102, and casters 103 for moving a refrigerator are attached to both ends. ing. A duct 105 in which a bottom condenser 104 is installed is disposed in front of the machine room base 100. The duct 105 is mounted on the front end 100a of the machine room base 100 with the rear end 105a of the duct fixed by a clip 106 or the like. By doing so, it is attached to the machine room base 100.
[0004]
[Problems to be solved by the invention]
The machine room table 100 has a portion that is easily deformed by a load. For example, since the weight of the refrigerator is concentrated on the mounting portion of the caster 103, the periphery thereof is very easily deformed.
[0005]
Further, since the compressor 101 is usually installed on the machine room base 100 with the four-legged support 102, the load applied to the grounding portion of the support 102 is large, and the portion is easily deformed.
[0006]
Further, the front end 100a of the machine room table 100 on which the rear end portion 105a of the duct 105 is placed is easily deformed around the center in the width direction by the load of the compressor 101 arranged at the center of the machine room table 100. Has become.
[0007]
Conventionally, in order to increase the strength of such a machine room base, for example, there is a case where a measure is taken to increase the sheet thickness from a normal 1 mm to 1.6 mm, but in this case, a press forming machine is enlarged by increasing the sheet thickness. This involves problems such as equipment changes and material cost increases.
[0008]
Further, there is a case where a reinforcing member as a separate member is mounted on the machine room base to increase the strength, but this involves problems such as an increase in the number of mounting steps, securing of a mounting space, deterioration of workability, and an increase in cost.
[0009]
In particular, in the mounting portion of the caster 103, it is conceivable to increase the strength by forming the surrounding flat portion as small as possible. However, space is required due to the mounting property of the machine room base component such as the caster 103. Therefore, there is a problem that it is not possible to sufficiently increase the strength for the reason that it is necessary to secure the strength.
[0010]
Therefore, an object of the present invention is to provide a machine room base that can reinforce a portion of the machine room base to which a load is applied with a low-cost and easily assemblable configuration and suppress deformation thereof.
[0011]
[Means for Solving the Problems]
The machine room base of the refrigerator according to claim 1 of the present invention is a machine room base which is disposed on the bottom surface of the refrigerator main body and is made of a plate-like member on which a compressor is mounted, and is provided in front of the machine room base for a bottom surface condenser. In the one to which the duct is attached, the front end of the machine room base on which the rear flange of the duct is placed is bead-formed in a convex shape so that the rear flange and the bottom surface of the refrigerator main body block the duct and the machine room. Casters for moving the refrigerator are attached to both ends in the width direction of the machine room base, and in order to secure a gas path between the machine room and the duct at one end in the width direction at the front end of the machine room base. The bead is formed so that the front end of the machine room stand is formed with the exception of the one end, and the end of the bead of the front end on the one end side is connected to the caster mounting portion on the one end side. Specially molded To.
[0012]
According to the machine room stand of the first aspect, since the caster surrounding portion of the machine room stand where the weight of the refrigerator is concentrated is reinforced by bead molding, deformation of the caster surrounding portion due to the load is suppressed.
[0013]
According to a second aspect of the present invention, there is provided a machine room base of a refrigerator according to the first aspect, wherein the casters are supported by the machine room bases at both ends of a rotation shaft thereof, and the beads are disposed in parallel with the axial direction of the casters. It is characterized by the following.
[0014]
When the casters are mounted on the machine room base at both ends of the rotation shaft, the caster peripheral portion of the machine room base is susceptible to bending deformation in the caster axial direction. By arranging them in parallel with each other, such bending deformation can be effectively suppressed.
[0018]
According to the machine room stand of claim 3 , since the front end of the machine room stand is formed into a convex shape so that the rear flange of the duct has a sealing structure with the bottom surface of the refrigerator body, sufficient strength can be increased. As a result, the front end of the machine room stand is less likely to be deformed, and the space between the machine room and the duct in front of the machine room can be closed in this bead-formed portion without using another member such as a wind shield. it can. Also, when a gas path is secured between the one end in the width direction of the machine room base and the front duct, the bead at the front end cannot be provided with the entire width of the machine room base. The effect of reinforcement cannot be obtained. Therefore, as described above, by providing a bead that connects the bead at the front end and the mounting portion of the caster in the portion where the gas path is secured, it is possible to reinforce the entire width of the machine room base.
[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 5, a machine room base 10 in which a compressor 12 and the like are installed is arranged in a machine room 8 at the bottom of the refrigerator. The machine room base 10 is fixed to the rear side of the bottom surface of the refrigerator body 6. ing.
[0024]
The machine room base 10 is a metal plate-shaped member formed by a press forming machine, and has a substantially rectangular shape elongated in the width direction of the refrigerator as shown in FIG. And is reinforced by a convex bead 11 extending to the front.
[0025]
A compressor 12 is installed at the center in the width direction of the machine room base 10, and casters 14 for moving the refrigerator are attached to both ends in the width direction. In addition, a duct 18 for the bottom condenser 16 is arranged in front of the machine room base 10, and further, as shown in FIG. 2, at the left end of the machine room base 10 (left side when viewed from the front of the refrigerator; the same applies hereinafter). Is equipped with a fan 20 for radiating heat in the machine room.
[0026]
Hereinafter, the reinforcing structure of the machine room base 10 will be described in detail.
[0027]
First, the reinforcing structure around the caster will be described.
[0028]
As shown in FIG. 1, the mounting portions 22 of the casters 14 are provided at both ends in the width direction at the rear of the machine room base 10, and are formed in a shape protruding from the flat portions 23 of the machine room base 10. ing. As shown in FIGS. 3 and 4, the mounting portion 22 is provided with a rectangular opening 24, and mounting flanges 25, 25 extend downward from the left and right opening edges. The left and right mounting flanges 25, 25 support both ends of the rotating shaft 14a of the caster 14, so that the caster 14 is disposed in the opening 24 with its axial direction directed in the width direction of the refrigerator. I have.
[0029]
A groove-shaped bead 26 which is slightly depressed downward is formed on the mounting portion 22 of the caster 14 so as to surround the caster 14. More specifically, as shown in FIG. 3, beads 26a, 26a extending parallel to the axial direction of the caster 14 are provided at the mounting portion 22 at the left end of the machine room base 10 so as to sandwich the caster 14 in the front-rear direction.

On the other hand, in the mounting portion 22 at the right end of the machine room base 10, as shown in FIG.
[0030]
As described above, since the bead 26 is formed around the caster around the machine room base 10 where the weight of the refrigerator is concentrated and reinforced, the cost can be reduced without using a separate member or deteriorating the mountability of the caster 14. In addition, with a configuration that can be easily assembled, deformation of the caster peripheral portion can be suppressed.
[0031]
Further, since the bead 26a is arranged in parallel with the axial direction so as to sandwich the caster 14, such a bending deformation can be effectively suppressed in the periphery of the caster which is easily subjected to the bending deformation in the axial direction of the caster 14.
[0032]
The bead 26 may be formed in a convex shape instead of being formed in a concave shape as in the present embodiment. However, forming into a concave shape is more effective against deformation of the caster peripheral portion.
[0033]
Next, the reinforcing structure of the installation portion of the compressor 12 will be described.
[0034]
As shown in FIG. 1, the compressor 12 is mounted on the machine room base 10 via four support members 28. Specifically, a mounting plate 30 having a small hole into which the head of the cylindrical support 28 is inserted is fixedly provided at the bottom of the compressor 12. The projection 30 is provided upright on the bottom of the support 28. The compressor 12 is mounted on the machine room base 10 by arranging the support 28 on the projection 30 and inserting and fixing the head of the support 28 into the small hole of the mounting plate 30. You.
[0035]
In the present embodiment, a portion of the flat portion 23 of the machine room base 10 where the support 28 is grounded is formed to be slightly wider than the support 28 and is reinforced to be concave. More specifically, the concave shaped portion 32 of the support 28 that is grounded has a concave shape slightly depressed downward, and is formed to be elongated in the width direction so that the left and right support legs 28 are grounded. Are formed one before and after the other.
[0036]
As described above, by forming the support grounding portion of the machine room base 10 where the support 28 of the compressor 12 is grounded into a concave shape slightly wider than the support 28, the planar shape of the portion of the compressor 12 to which the load is applied is formed. Becomes smaller, the strength is increased, and deformation becomes difficult. Further, with the concave shaped portion 32, it is possible to suppress deformation of the compressor 12 due to a load with a configuration that can be easily assembled at a low cost without impairing the mountability of the compressor 12.
[0037]
Next, a reinforcing structure of the front end of the machine room base 10 will be described.

As shown in FIG. 5, the projecting height of the bead 34 at the front end portion is such that the rear flange 18a of the duct 18 placed on the upper surface abuts on the bottom surface of the refrigerator body 6 via the sealing material 38, The portion where the bead 34 is formed is set so that the space between the duct 18 and the machine room 8 is shut off.
[0040]
As described above, the bead 34 at the front end of the machine room base 10 is formed large until the rear flange 18a of the duct 18 forms a seal structure with the bottom surface of the refrigerator main body 6, so that the front end of the machine room base 10 is sufficiently formed. Thus, the strength of the machine room table 10 due to the load of the compressor 12 can be suppressed. Further, a part of the front side of the machine room 8 in the width direction can be closed by bead forming of the front end of the machine room base 10 without using a separate member such as a wind shield plate. Excellent.
[0041]
The bead 34 at the front end of the machine room base 10 is not provided at the entire width of the front end in order to secure the gas path 40 at one end in the width direction of the machine room base 10, and the front end bead is formed at the one end. Is formed flat. That is, as shown in FIG. 1, the rear flange 18a of the duct 18 is notched at the left end, and no bead 34 is formed at the left end of the front end of the machine room base 10 so as to correspond to the notch 18b. . As a result, as shown in FIG. 2, the air G that has entered from the front of the duct 18 enters the machine room 8 through the gas path 40 through the duct 18, and the fan 20 disposed at the left end of the machine room base 10.
