As a refrigerant in the refrigeration cycle, isobutane, which is a flammable refrigerant with a low global warming potential, is used from the viewpoint of global environmental conservation.

  Moreover, the recessed part of the heat insulation box 401 is provided with the side wall 460 on the right and left, and the recessed part 450 forms the outer plate | board 430a which forms the outer frame of a top | upper surface part, a side part, and a bottom face part, and the outer frame of a back part, for example The outer frame of the heat insulating box 401 is formed by the outer box 430 formed by the outer plate 430b to be formed and the outer plate 430c having high rigidity formed according to the shape of the recess 450.

  Further, since the compressor 420 is disposed on the outer plate 430c that forms the outer frame of the recess, the compressor 420 is designed to have higher rigidity than other outer frame portions of the heat insulating box. The recess 450 is covered with a cover 433 provided over almost the entire width in the left-right direction after the compressor or the like is accommodated. The cover 433 is provided with a ventilation hole 434 that promotes the flow of air in the recess. Further, a reinforcing member 435 is embedded in the side wall 460 of the recess 450 for the purpose of increasing the strength of the side wall and serving as a support portion when the handle 436 that is a reinforcing member extending in the left-right direction is attached to the side wall. Yes. Further, the reinforcing member 435 is made of a metal having a high strength that can secure the strength to which the handle 436 is attached. The reinforcing member 435 is fixed to the outer frame side and is held in close contact with the heat insulating wall by a foam heat insulating material. The reinforcing member 435 also has an object of preventing deformation when the side wall of the recess is filled with the foam heat insulating material.

  The reinforcing member 435 is made of a dog-shaped iron material extending forward and downward from the vicinity of the upper back side corner portion 460a of the side wall 460, and further, a cross section of a portion provided on the side wall side and the back wall side corner and the side wall side The shape is substantially L-shaped.

  The handle 436 for carrying the refrigerator is a handle bar that has both ends fixed to both side walls of the recess 450 and is provided in the left-right direction of the machine room, and has strength in the left-right direction on the back side of the recess 450. A reinforcing structure having a reinforcing function to reinforce is formed.

  Thus, since the heat insulation box 401 is provided with the recessed part 450, the level | step-difference part 451 is formed in the store | warehouse | chamber interior of the refrigerator compartment 410. FIG.

  Further, the heat insulating box 401 is filled with a foam heat insulating material 432 in a space formed by the outer box 430 and the inner box 431 formed so as to surround the top surface, the side surface, the back surface, and the bottom surface of the refrigerator. 401. When filling the heat insulating box 401 with the foam heat insulating material 432, the partition 437 that insulates the refrigerator compartment and the partition 438 that insulates the freezer compartment 413 having the large front opening area after the refrigerator compartment 410 and the insulator box 401. By simultaneously filling the foam heat insulating material 432 with each other, the heat insulating walls forming the refrigerator compartment 410 and the freezer compartment are integrated. Since the refrigerator compartment has a stepped portion 451, it has a complicated shape, but all the heat insulating walls forming the refrigerator compartment including the stepped portion 451 are integrally formed.

  Thus, when filling the foam heat insulating material 432, in the recess 450, the outer plate 430a that forms the outer frame of the top surface portion, the side surface portion, and the bottom surface portion, the outer plate 430b that forms the outer frame of the rear surface portion, and the recess After assembling the outer box 430 formed of the outer plate 430c having high rigidity formed according to the shape of 450, the vacuum heat insulating material 440 is provided on the inner box side between the bottom surface of the recess 450 and the inner box 431. , The reinforcing member 435 is provided on the outer box side of the side wall 460 of the recess, and the foam heat insulating material 432 is filled, so that the periphery of the recess 450 is formed with high strength.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The high-temperature and high-pressure refrigerant discharged by the compression operation of the compressor 420 exchanges heat with a condenser (not shown) to dissipate heat and condensates and reaches a decompressor (not shown). Thereafter, the pressure is reduced by the pressure reducer, reaches an evaporator (not shown), and is again sucked into the compressor.

  At this time, when a compression operation is performed by the compressor 420, a large vibration is generated, and the vibration from the compressor 420 becomes a vibration generation source of the refrigerator, but a recess that is a machine room in which the compressor is disposed. 450 includes a handle 436 that is a reinforcing structure that reinforces the strength in the left-right direction of the outer shell of the machine room. Therefore, the rigidity of the heat insulating wall that forms the recess 450 is high, and vibration generated from the compressor 420 is generated. Propagation of vibration to the refrigerator body can be suppressed. In addition, it is possible to suppress vibrations generated from the compressor from propagating to other parts (for example, the food storage shelf 410c in the refrigerator) and causing chatter and noise due to the vibrations of the parts.

  Further, the handle 436 is fixed with a screw with a cover 433 sandwiched between reinforcing members 435 attached to the side of the outer side of the side wall 460 of the concave portion 450.

  With this configuration, the reinforcing member 435 positioned at the attachment portion of the handle 436 is reinforced so as to have sufficient strength to hold the handle 302, so that the heat insulating box whose strength is weakened by the space portion of the recess 6. In addition to increasing the strength around the concave portion 450 of the body, the attachment strength of the handle 436 can also be increased, and the load on the handle during transportation is large due to the higher center of gravity position of a heavy refrigerator with a large capacity weight Ensure that the refrigerator can be transported safely.

  Further, in the present embodiment, the attachment position of the handle is on the back side, for example, when the refrigerator is transported diagonally backward compared to the type in which the attachment position of the handle is on the top surface side. The load applied to the attachment surface 436a of the handle 436 is different when a force is applied to pull the handle upward. For example, when the handle is attached to the top surface side, the handle is easily removed in the screw insertion direction. When the force in the direction acts, there is a concern that the mounting strength of the handle may be reduced due to deformation of the screw and deformation of the mounting surface, whereas when the mounting surface 436a of the handle 436 is on the back side, insertion of the screw A force in a direction that is difficult to pull out acts on the direction, and the load of the refrigerator is attached to the attachment surface 436a of the handle 436. The entire surface 436a is subjected to a load that receives the load of the refrigerator. The attachment surface 436a of the handle 436 is not deformed due to deformation of the screw, and the attachment strength of the handle 436 is further improved and the refrigerator is transported. Therefore, the safety at the time of carrying a refrigerator can be improved more.

  Further, in the present embodiment, various ideas are made in the refrigerator compartment 410 in order to increase the rigidity around the recess 450 where the vibration of the compressor is directly transmitted.

  First, when the heat insulating wall that forms the refrigerator compartment 410 is integrated, the heat insulating wall that forms the concave portion 450 has high rigidity with the outer plate 430c formed according to the shape of the concave portion 450 as a separate component. These are provided and then integrally molded by filling with a foam heat insulating material 453, and further, a foam heat insulating material 432 is provided in the recess 450 which is a heat insulating wall between the compressor 420 and the refrigerator compartment 410. In addition, a vacuum heat insulating material 440 is provided.

  Since this vacuum heat insulating material 440 has higher rigidity than the foam heat insulating material 432, it has an effect as a reinforcing member for the recess 450. Further, since the heat insulating effect of the vacuum heat insulating material 440 is about 2 to 3 times higher than that of the foam heat insulating material 432, it is possible to prevent the heat amount from entering the refrigerating chamber 410 from the high temperature compressor 420, and the uppermost part from the compressor. Since the amount of heat intrusion into the storage room can be significantly reduced, the power consumption of the refrigerator can be suppressed.

  Furthermore, in addition to the damping effect on the noise transmission of the foam insulation located between the compressor 420 and the inside of the refrigerator compartment 410, a vacuum insulation with different or different structure as a core material is made into a multilayer structure. As a result, the attenuation effect on noise transmission can be further enhanced and the noise in a wider frequency range can be attenuated compared to the case of sound insulation with a single material, thus reducing the leakage of noise transmitted into the cabinet. And the noise of the refrigerator can be reduced.

  Furthermore, since the reinforcing member 435 is provided on the side wall of the concave portion 450, the strength of the side wall of the concave portion, which tends to be weak in rigidity, can be increased. Propagation to parts (for example, refrigerant pipes, control bases, etc.) provided in the recesses and the occurrence of chatter and noise due to vibration of the parts can be suppressed.

  Further, the reinforcing member 435 is arranged in the shape of a dogleg in the depth and depth directions of the recess 450, and is projected over the side wall of the recess 450 and the front wall surface 450a and the bottom surface 450b of the recess 450 when projected onto the side wall. Since it is provided over a distance, the side wall 460 can be supported as a part of a continuous heat insulation box supported by the front wall surface 450a and the bottom surface 450b of the recess 450, which is a heat insulation wall perpendicular to the side wall 460. The strength of the opening of the recess 450 can be increased.

  Further, by attaching the handle 436 to the opening of the concave portion 450 through the reinforcing member 435 so as to cross the left and right of the concave portion 450, the strength around the concave portion of the heat insulating box whose strength is weakened by the space portion of the concave portion 450 Since the side wall of the recess 450 can be configured as a continuous rigid body, the strength of the refrigerator compartment 410 and the recess 450 can be further increased.

  The reinforcing member 435 to which the handle 436 is attached is made of a iron-shaped iron material extending forward and downward from the vicinity of the upper back side corner portion 460a of the side wall 460, and further, the side wall side and the back wall side corner and side wall side. The cross-sectional shape of the portion provided in is substantially L-shaped. Thus, the cross section is L-shaped, and these surfaces are provided over two adjacent wall surfaces, so that the two wall surfaces provided with the L-shaped reinforcing member 435 are configured as a continuous rigid body, and are reinforced. The attachment strength of the member to the refrigerator main body can be greatly improved. Further, in the present embodiment, the reinforcing member 435 has a square shape extending forward and downward from the vicinity of the upper back side corner portion 460a of the side wall 460, so that the side wall, the back wall, and the top side of the refrigerator outer frame are mutually connected. Adjacent three surfaces are connected by a single reinforcing member 435, which has a large strength centering around the upper back side corner portion 460a where the three surfaces contact, so that by attaching a handle 436 to this portion, the reinforcement The handle 436 can be supported by using the structure, the strength of the handle 436 during transportation can be greatly improved, and the center of gravity position has increased so that a load that is heavy on the handle during transportation is safe. To be transportable.

  Further, since the cover 433 covering the concave portion is fixed to the reinforcing member 435 of the side wall 460 of the concave portion 450, the strength of the cover member can be increased, and chatter and noise due to vibration of the cover member due to the vibration of the compressor can be prevented. Generation | occurrence | production can be suppressed.

  Therefore, in this Embodiment, the reinforcement structure of the handle 436 and the cover 433 is provided as a reinforcement structure which reinforces the intensity | strength in the left-right direction of the recessed part which is a machine room. As a result, the rigidity around the machine room, which tends to be weak due to the presence of the recesses, can be greatly improved.

  Further, the handle 436 is formed using the reinforcing structure after improving the rigidity in the left-right direction in this way, so that the strength of the handle 436 during transportation can be ensured, and the center of gravity position is The higher load makes it possible to safely transport a refrigerator with a large load on the handle during transportation.

  Further, since the cover 433 is provided with the ventilation holes 434 for promoting the flow of air in the recess 450, the air in the recess can be circulated effectively. Thereby, the temperature rise of a compressor can be suppressed and suppression of the power consumption of a refrigerator can be aimed at.

  As described above, the refrigerator according to the present embodiment can suppress the vibration generated from the compressor 420 from propagating to the refrigerator main body, and thus the refrigerator in which the compressor 420 is arranged on the top surface of the heat insulating box 401. Can provide a refrigerator realizing low vibration and low noise.

  In addition, the compressor 420 is disposed in the concave portion 450 at the back of the top surface of the heat insulating box 401, and the compressor is surrounded by a heat insulating wall on both the front side and the side wall, thereby generating noise generated from the compressor. Can be prevented from leaking to the front side of the refrigerator.

  In addition, since the compressor uses an internal low-pressure compressor, the mechanical part that compresses the refrigerant is supported via an elastic member such as a spring with respect to the sealed container that is the outer shell of the compressor. The vibration accompanying the compression operation does not directly propagate to the sealed container, and the sealed container is disposed in the heat insulating box 401 via the grommet 420a which is an elastic member, so that the vibration of the compressor 420 propagates to the heat insulating box. To prevent it.

  As described above, the refrigerator according to the present embodiment can suppress the vibration generated from the compressor 420 from propagating to the refrigerator main body, and thus the refrigerator in which the compressor 420 is arranged on the top surface of the heat insulating box 401. Can provide a refrigerator realizing low vibration and low noise.

  In the present invention, the vacuum heat insulating material 440 is provided on the front wall surface 450a and the bottom surface 450b of the recess 450 at a position corresponding to the front side and the bottom side of the compressor, but due to the design and cost of the refrigerator, There may be provided at least one of them.

  In the present invention, the reinforcing member 435 of the side wall 460 has a U-shape, but is provided from the space of the recess 450 to the front wall surface 450a and the bottom surface 450b on the projection surface on the side surface. If it is such a shape, even if it is other shapes, it is supported by the front wall surface 450a and the bottom surface 450b of the recess 450 that is a heat insulation wall perpendicular to the side wall 460, and the side wall 460 is supported as a part of a continuous heat insulation box. And the strength of the opening of the recess 450 can be increased.

  In this embodiment, the shape of the reinforcing member 435 to which the handle 436 is attached has a substantially L-shaped cross section, and is further bent into a dogleg shape. However, the load applied to the reinforcing member 435 is relatively small. In the case of application to a small product, it is possible to use a simplified reinforcing member 435 with a part of the shape having a relatively small influence.

  For example, the L-shaped cross-section is not a L-shaped cross section only on the opposite side of the handle 436 and the L-shaped cross-section with a single plate and only the side directly fixing the handle 436. By doing so, it is possible to save resources.

  In the present embodiment, the reinforcing member 435 is arranged in a U-shape in the depth and depth directions of the recess 450, and when projected onto the side wall, the inner space of the recess 450 and the front wall surface 450a of the recess 450 and Although it has been provided over a long distance over the bottom surface 450b, when applied to a product in which the load applied to the reinforcing member 435 is relatively small, the strength in the vicinity of the upper back side corner portion 460a is secured. Focusing and shortening the forward and downward extension of the character, for example, in the projection on the front or lower side walls, even if one of them is designed to be shorter to the inner space of the recess 450, the recess It is also possible to sufficiently secure the strength around the upper back side corner portion 460a.

  In the case where the focus is focused only on securing the strength for holding the handle and there is no need to fix the cover from the top surface, the reinforcing member 435 does not have to be a dogleg shape. In order to hold the handle even if there is no reinforcing member on the top surface side, for example, in the case where the cross section only on the side to which 436 is attached has an L-shaped cross section, for example, when the mounting portion of the handle is on the back side It is possible to ensure the strength.

  In addition, depending on the shape and material of the handle 436, if there is a concern that the outer shape and surface state of the grip part will be difficult to grip when gripped by the hand, or that the hand will be painful, These problems can be solved by adding an outer structure that improves transportability to the grip portion. Specifically, another part made of resin is put around the grip part of the handle part 210, or the other part is devised in a shape that makes it easy to grip, or it is made of a rubber-based material that is not slippery and has a high grip property. It is possible to respond by covering with.

  The refrigerator handle structure of the present invention is capable of transporting a refrigerator with a raised center of gravity without reducing the internal volume, using the compressor-mounted recess at the top of the refrigerator. It can also be applied to refrigeration equipment such as large commercial refrigerators and freezers and showcases.
