The machine room 19 includes a compressor 24 that compresses and discharges a refrigerant, a condenser 61 that exchanges heat between the refrigerant and air, and an external blower 26 that promotes heat exchange between the refrigerant and the air in the condenser 61; The pressure reducing means 63, which is a thin tube, and the refrigerant channel switching valve 70 are disposed.

  The compressor 24, the condenser 61, the pressure reducing means 67, and the refrigerant flow path switching valve 70 are connected to the cooler 7 and the condensation prevention pipe 62 by piping, and a refrigerant path (refrigerant circuit) through which the refrigerant flows is formed. It is supposed to be

  The refrigerant flow path switching valve 70 may be disposed downstream of the flow of the wind from the external fan 26. By disposing on the downstream side, the refrigerant flow switching valve 70 does not obstruct the flow of wind and the heat radiation of the condenser 61 and the compressor 24 is not deteriorated.

<Refrigerant route (refrigerant circuit)>
Next, the refrigerant path (refrigerant circuit) in the refrigerator 1 of the present embodiment will be described with reference to FIG.

The tube 67 and the evaporator 7 which is a cooling unit that cools the air by evaporating the refrigerant sent from the capillary tube 67 are sequentially connected by a tube through which the refrigerant flows.

  In the present embodiment, as the heat dissipating means, a condenser 61 (for example, a finned tube heat exchanger) disposed in the machine room 19 and heat dissipating pipes 62, 63, 64 are provided. An external blower 26 is disposed in the machine room 19, and by operating the external blower 26, heat radiation of the condenser 61 can be promoted.

  The heat radiation pipe 62 is disposed between the outer case 1a and the inner case 1b on both side surfaces and the ceiling surface of the heat insulation box 10 so as to be in contact with the outer case 1a surface. The outer case 1a is made of steel plate, and the heat is dissipated from the outer surface of the outer case 1a to the air outside the case.

  The heat radiation pipe 63 is disposed in the inner front of the upper heat insulation partition 51, the lower heat insulation partition 52, the horizontal partition 53, and the vertical partition 54 of the heat insulation box 10. Although these partition walls (partition parts) are in low temperature because they are in contact with the storage room, the front part is an opening edge of each storage room, so it is easy to be in contact with the outside air.

<A member for fixing the refrigerant flow path switching valve 70>
Next, the fixing member 80 for attaching the refrigerant flow switching valve 70 to the machine chamber 19 will be described with reference to FIG. FIG. 5A is a perspective view of the fixing member 80, and FIG. 5B is a top view of the fixing member 80.

  The fixing member 80 includes a valve support 81 for supporting the refrigerant flow path switching valve 70, an attachment 82 for attaching the fixing member 80 to the machine chamber 19, and a gap between the valve support 81 and the attachment 82. It is comprised by the damping part 83 to connect.

  The valve supporting portion 81 has a floor portion 81a which is hollow and ring-shaped and whose outer edge is erected upward, and a gap 88 which connects the central region of the floor portion 81a which is a space and the outer space of the valve supporting portion 81 A hook 85 disposed on the upper surface of the floor 81a and a locking hook 86 whose one end is connected to the outer peripheral side of the standing portion of the floor 81a and which extends upward.

  The refrigerant channel switching valve 70 can be placed on the upper surface side of the floor 81 a, and the refrigerant channel switching valve 70 can be supported and fixed to the fixing member 80 by the claws 85. A plurality of claws 85 are disposed on the floor 81 a at substantially equal angular intervals.

  The locking claws 86 extend perpendicularly to the floor and are located outside the annular area of the floor. The locking claw 86 is also used as a rotation stopper in the circumferential direction by coming into contact with a rib 73 provided to project on the outer peripheral side surface of the stator 72 of the refrigerant flow switching valve 70 described later. The member provided on the outer peripheral side surface of the stator 72 may not necessarily be the rib 73, and may be a member that can be locked by the locking claw 86.

  The valve support portion 81 is formed as a shape having a space 88 connecting the space inside the floor portion 81 a and the outer region of the floor portion 81 a. By utilizing the air gap 88, the stator 72 side of the refrigerant flow switching valve 70 is positioned above the floor 81a, and the pipe provided on the lower surface of the refrigerant flow switching valve 70 is positioned below the floor 81a. It will be easier to locate. That is, the mounting of the refrigerant flow switching valve 70 on the fixing member 80 is facilitated, and the workability can be improved.

  The mounting portion 82 has a substantially L-shaped shape, is located on the outer peripheral side of the valve support portion 81, and extends in a direction parallel to the floor portion 81a, and a floor portion A second extending portion 82b extends in a direction perpendicular to 81a and has one end connected to one end of the first extending portion 82a. In the vicinity of the tip on the other end side of the second extending portion 82b, a device mounting member installation portion capable of fixing a device mounting member for fixing the fixing member 80 to the machine chamber 19 is opened. In the present embodiment, the device mounting member and the device mounting member mounting portion will be described as the screw and the screw hole 87. The hooks 86 and the second extension 82b extend on the same side (upward in this embodiment) with respect to the floor 81a.

  The first extending portion 82a has a lattice shape in top view. As a result, the material used for the fixing member 80 can be reduced while securing the strength.

  The second extension 82 b has a projection such as a rib on the surface opposite to the side where the valve support 81 is located. Thereby, when the fixing member 80 is attached to the wall surface or the like of the machine chamber 19, it is possible to suppress the whole surface of the second extending portion 82b from being in contact with the wall surface, and to suppress the propagation of vibration.

  By providing the first extending portion 82a, the second extending portion 82b can be set at a position shifted in the left-right direction from the projection of the valve. This makes it possible to secure a space for providing a damping unit 83 described later, and a pipe provided at the lower part of the refrigerant flow switching valve 70 is used as a space on the projection of the valve. It becomes possible to arrange at the shortest distance.

  The damping portion 83 is provided between the valve support portion 81 and the mounting portion 82. The damping portion 83 is integrally formed with the valve support portion 81 and the mounting portion 82, and has a wave shape. The wave-like shape of the damping portion 83 can be, for example, a U-shape, an S-shape, a V-shape, a W-shape, or a shape combining a plurality of these. By adopting such a wave shape, it is possible to deform the shape according to the vibration when the refrigerant flow path switching valve 70 is driven, and to suppress the vibration propagation from the valve support portion 81 to the attachment portion 82. The vibration propagating to the refrigerator 1 can be reduced.

  The valve support portion 81 and the attachment portion 82 are connected by a plurality of damping portions 83, and a part or all of one damping portion 83 is provided in a part of the grid-like region of the first extension portion 82a. be able to. Accordingly, the fixing member 80 can be miniaturized while securing the installation space of the damping portion 83. The damping part 83 provided in the first extending part 82a is located not inside the end of the first extending part 82a but inside. Further, different damping portions 83 are provided on both sides of the damping portion 83 in the horizontal direction. The additional damping portions 83 are respectively connected to the grid-shaped outer edge of the first extending portion 82a.

  The wave shape of the damping part 83 of this embodiment is a structure that can be easily moved in the horizontal direction. Specifically, the wave shape can be observed in top view. When the vibration caused by the rotation of the stepping motor mounted on the refrigerant flow channel switching valve 70 is stronger in the horizontal direction than the vertical direction, vibration propagation to the refrigerator 1 is achieved by adopting such a structure. Can be easily suppressed. For example, in the case where there is a member that rotates in a direction substantially parallel to the floor surface by the stepping motor, such a configuration is preferable.

  Moreover, as a material of the fixing member 80, it is desirable to form with a synthetic resin material. For example, polypropylene, ABS resin, acrylonitrile can be used. By adopting such a synthetic resin material, it becomes easy to form the valve support portion 81, the damping portion 83 and the mounting portion 82 as an integral part, and a lightweight and inexpensive structure without increasing the number of parts. can do.

<Attachment of Refrigerant Channel Switching Valve 70 to Refrigerator 1>
FIG. 6 is a perspective view showing the fixed member 80 with the refrigerant flow switching valve 70 installed. The refrigerant channel switching valve 70 has a stepping motor on the upper surface side and is covered with the stator 72, and a plurality of pipes 76 and 77 extend downward from the lower surface. The pipes 76 and 77 can easily attach the refrigerant flow switching valve 70 by passing the air gap 88 described above.

  The stator 72 has a hook 85 at the bottom and a recess or a projection capable of locking the hook 86 at the side. After the refrigerant flow switching valve 70 is placed on the floor portion 81a and fixed using the claws 85 and the locking claws 86, the screws 75 and the like are inserted into the wall of the machine room 19 and the screw holes 87, It fixes to the predetermined position of the chamber 19 wall surface. By fixing the refrigerant flow switching valve 70 to the refrigerator 1 by the fixing member 80, the posture of the refrigerant flow switching valve 70 in each of the manufacturing, transport and use states of the refrigerator can be made the refrigerant flow switching valve 70 main body.

Connect with and weld. Next, wiring (not shown) for the stepping motor is connected, and the attachment of the refrigerant flow switching valve 70 is completed.

  In the mounting structure of the refrigerant flow switching valve 70 in the refrigerator 1 having the above configuration, since the refrigerant flow switching valve 70 is mounted by the fixing member 80 having an elastic shape, the vibration of the stepping motor causes the fixing member 80 to be fixed. Can be suppressed from being transmitted to the heat insulation box 10 through the above, and noise can be reduced. In particular, when the fixing member 80 is formed of a synthetic resin, the rigidity of the material is smaller than that of metal, so that the fixing member 80 can be deformed according to the vibration, and the vibration transmission of the motor can be suppressed.

  Further, by using a synthetic resin material as the material of the fixing member 80, it becomes possible to integrally form the valve support portion 81, the damping portion 83, and the mounting portion 82, thereby reducing the number of parts for fixing. Can. For this reason, material cost and assembly workability can be improved, and an inexpensive structure can be provided.
