Description

  The present invention relates to a refrigerator in which a compressor is mounted in a recess on the top surface of the refrigerator.

  In recent years, refrigerators are required to be more energy-saving from the viewpoint of protecting the global environment, and to be further silenced from the viewpoint of improving usability and storage capacity, as well as improving amenities.

  Hereinafter, the conventional refrigerator will be described with reference to the drawings.

  Conventionally, this type of refrigerator has a method in which a compressor or the like forming a machine room is installed on the top surface of the refrigerator main body, which is inconvenient when viewed from the user side, or on the upper back of the refrigerator main body (for example, , See Patent Document 1).

  FIG. 22 is a structural sectional view of a conventional refrigerator, and FIG. 23 is a longitudinal sectional view of a conventional refrigerator compressor.

  Generally, a refrigerator discharges cold air generated by a refrigeration cycle in which a compressor 50, an evaporator 28, a condenser (not shown), and an expander (not shown) are connected by piping or the like, It is used to reduce the temperature of food and store foods and the like frozen or refrigerated.

  The box body 1 of the refrigerator is composed of a refrigerator room 7, a vegetable room 10, and a freezer room 11 from above.

  The refrigerating chamber 7 has a rotary door 13 that is a rotary type with one end portion rotatably supported via a hinge 12 on the front surface of the box body 1. The vegetable compartment 10 has a drawer door 15d that is slidable forward and backward via rails (not shown), and the freezer compartment 11 is also reciprocated similarly to the vegetable compartment 10. It has the drawer door 15c which is a formula.

  The inner edges of the revolving door 13 and the drawer doors 15c and 15d are in close contact with the sealing surface 17 of the box body 1 so as to block the inside and outside of the refrigerator and absorb the impact when the door is closed. A gasket 16 is attached.

  In addition, a plurality of door pockets 14 for storing food and the like are provided inside the rotary door 13.

  Above the box body 1, a recess 20 is provided that is recessed toward the refrigerator compartment 7 over the top surface 18 and the back surface 19 of the box body 1. The refrigerator compartment 7 is provided with a plurality of storage shelves 21 for storing foods, etc., but the uppermost section partitioned by the uppermost shelf 22 that is generally not easy to use as viewed from the user side. The back side of the storage space 22a and the second-stage storage space 23a protrudes in a convex shape by a recess 20 provided in the upper back of the box body 1.

  The recess 20 is provided with a compressor 50, a machine room fan 90, a condenser (not shown), a dryer (not shown), and the like.

  The compressor 50 houses an electric element 58 composed of a stator 60 and a rotor 62 and a compression element 63 driven by the electric element 58 in an airtight container 52 (see, for example, Patent Document 2).

In the compression element 63, the crankshaft 68 supported by the block 59 rotates as the rotor 62 rotates, and the rotational movement of the eccentric shaft portion 67 of the crankshaft 68 is transferred to the piston 65 via the connecting means 69. Accordingly, the piston 65 reciprocates in the bore hole 73 formed in the block 59 to suck and compress the refrigerant 53, and is generally used in a domestic refrigerator.

  However, in the above-described conventional configuration, when the rotary door 13 is closed in a state where food or the like is stored in the door pocket 14 of the rotary door 13, the gasket 16 and the seal surface 17 of the box body 1 collide with each other. The impact force that cannot be absorbed by the heat is transmitted from the seal surface 17 to the box body 1 and the refrigerator may swing back and forth. At this time, the inner wall of the sealed container 52 of the compressor 50 and the compression element 63 may come into contact with each other, and so-called hook contact noise may be sporadically generated.

  In addition, when the sealed container 52 and the block 59 constituting the compression element 63 come into contact with each other, since both are formed of metal, metal chipping pieces (fine fragments) are generated, and this is the block 59 and the crankshaft 68. If it is caught between shaft slides as represented by, abnormal wear and incompressibility (lock) may occur.

  On the other hand, a refrigerant pipe (not shown) for conveying the compressed refrigerant 53 to the next stroke, for example, a discharge thin tube, is disposed in the compressor 50. When frequent contact is made with the components constituting the element 63, metal fatigue accumulates intensively at the contact site, eventually leading to brittle fracture of the discharge capillaries and the possibility of the compressor 50 becoming incompressible.

The discharge thin tube 171 is formed to have high rigidity. That is, the discharge thin tube 171 that elastically connects the compression element 163 and the discharge pipe 140 that is a high-pressure pipe provided in the sealed container 152 has a collision direction that collides with the box body 101 when the rotary door 113a is closed. By having the portion 171a formed in a substantially parallel direction, the rigidity in a direction substantially parallel to the collision direction that collides with the box body 101 when the rotary door 113a is closed is increased. Of course, the portion 171a formed in a direction substantially parallel to the collision direction is not limited to a straight line but may have a curved line or a curved portion. In addition, the discharge thin tube 171 and the discharge tube 140a of the sealed container 152 are elastically joined at the connection portion 181.

  A plurality of legs 155 are fixed to the lower side of the sealed container 152, and elastic members are fixed to pins 127 fixed to the recess 120 of the refrigerator via elastic members 156 locked to the legs 155. The position is fixed by loosely fitting the hole 157 of 156. The pitch Wm between the legs 155 in the parallel direction with respect to the front surface 143 of the refrigerator is formed to be longer than the diameter Wc of the sealed container 152 in the parallel direction.

  Next, the impact force at the time of collision with the box body 101 when the rotary doors 113a and 113b are closed and the influence on the compressor 150 will be described.

  The arc 132a is an opening / closing locus of the end of the rotating door 113a opposite to the hinge 112 side, and the arc 132b is an opening / closing locus of the end of the rotating door 113b opposite to the hinge 112 side.

  In general, there is angular momentum as a quantity representing the momentum of the rotating body. Angular momentum is proportional to each of mass, circumferential speed, and rotational radius. That is, when the rotary doors 113a and 113b are closed, the larger the angular momentum given to the rotary doors 113a and 113b, the side that receives the rotary doors 113a and 113b and the rotary doors 113a and 113b, that is, the seal surface of the box body 101. The impact force generated at the time of the collision 117 is increased. Further, the impact force affects the vertical direction with respect to the front surface 143 of the refrigerator.

  The rotary door 113b will be described as an example. The factor that affects the overall angular momentum is the mass immediately before the collision between the rotary door 113b and the food stored in the door pocket 114 and the seal surface 117. The circumferential speed of the revolving door 113b and the lateral width of the revolving door 113b, that is, the radius of the arc 132a of the opening / closing locus of the revolving door 113b. These dominate the overall impact force applied to the refrigerator box body 101 when the gasket 116 and the seal surface 117 collide.

  Further, from the viewpoint of the distribution of the angular momentum given to the rotary door 113b, the circumferential speed increases as the point moves away from the hinge 112, which is the rotation fulcrum of the rotary door 113b, and the angular momentum increases. If food or the like is stored in the door pocket 114 without being biased, normally, the angular momentum is maximized at the extreme end of the revolving door 113b opposite to the hinge 112.

  When the revolving door 113b is closed, a magnetic force acts between the permanent magnet built in the gasket 116 and the seal surface 117 made of a magnetic material, and the gasket 116 comes into close contact with the seal surface 117. At this time, although the air pocket built in the gasket 116 absorbs the impact force to some extent, the impact force that cannot be absorbed is transmitted to the box body 101 of the refrigerator through the seal surface 117.

  Nowadays, the main capacity of the main refrigerator capacity band is 300L or more. Thereby, as the refrigerator size increases, the radius of the arc 32 that is the opening / closing locus of the rotary door 13 increases, and in addition, the storage amount in the door pocket 14 increases, so that the rotary door 13 combined with stored items and the like. It is inferred that the total weight of the inevitably becomes heavy, and the impact force applied to the box body 1 when the rotary door 13 is closed increases synergistically.

  Hereinafter, the mechanism per hook of the compressor will be described with reference to FIG.

  The discharge tube 140 a and the suction tube 141 a formed on the side surface of the sealed container 152 are welded to the discharge pipe 140 and the suction pipe 141 formed on the refrigerator side, respectively, and are fixed below the sealed container 152. Since the leg 155 is fixed to the installation surface 120a of the recess 120 via the pin 127, it can be said that the sealed container 152 constituting the outer shell of the compressor 150 is in a state of being restrained by the refrigerator. . Therefore, when the refrigerator swings in the front-rear direction (arrow B1 direction, B2 direction in the figure) due to the impact (arrow A in the figure) from the front surface 143 when the rotary door 113b is closed, the sealed container 152 is pulled to the refrigerator. In the same manner, it will swing back and forth.

  On the other hand, inside the compressor 150 at the moment when an impact is applied, the mechanical force 174, which is a mechanical part composed of the compression element 163 and the electric element 158, has an inertial force apparently in the B2 direction due to elastic support (see FIG. 4). In addition to the action, the support 160a fixed to the bottom of the sealed container 152 is displaced in the direction of the arrow B1 along with the vibration of the sealed container 152 and welded to the discharge tube 140a fixed to the sealed container 152. The force that pulls the mechanism 174 in the direction of the arrow B <b> 1 through the discharged narrow tube 171 acts, and the spring 170 is twisted. Thereafter, due to the restoring force due to the elasticity of the spring 170 and the discharge thin tube 171, the mechanism 174 causes the arcuate arrows C 1 and C 2 in the direction of the arcs centering on the connection portion 181 where the discharge thin tube 171 and the discharge tube 140 a of the sealed container 152 are joined. Will swing around.

  Therefore, in the present embodiment, the end 150b of the compression element on the side facing the side where the discharge thin tube 171 is disposed with respect to the central axis 150a in the left-right direction of the compressor 150, and the rotary door 213b on the left and right. It is arranged avoiding the projection line from the front of the dividing line 130 to be divided.

  As a result, the opening / closing locus radius of the rotary door 213b is reduced to reduce the angular momentum of the rotary door 213b as a whole, and among the angular momentum of the rotary door 213b, from the projection line from the front of the largest dividing line 130, At least the portion of the compressor 150 that is likely to vibrate because it is separated from the connecting portion 181 of the sealed container 152 and the mechanical portion consisting of the compression element 163 and the electric element 158 is separated from the hook of the compressor 150. Therefore, it is possible to provide a highly reliable refrigerator that can be suppressed and quiet.

  It is considered that the swinging of the sealed container 152 and the swinging of the mechanism 174 contacted the mechanism 174 and the inner wall of the sealed container 152 to generate a so-called hook contact.

  However, in the present embodiment, the two rotary doors 113a and 113b are provided so as to open to the left and right sides at the dividing line 130 that divides from the middle of the door 105 of the refrigerator compartment 107 into a ratio of 4: 6. The compressor 150 is disposed so as to avoid the projection line 131 from the front of the dividing line 130.

  Thereby, the arc 132a and the arc 132b radius of the opening / closing locus of the rotating doors 113a and 113b are smaller than the conventional one, and the rotating doors 113a and 113b are used as two pieces to distribute the stored items in the rotating doors. The total weight of the revolving doors combined with the weight of food to be stored is apparently lightened, the overall angular momentum given to the individual revolving doors 113a and 113b is reduced, and the refrigerator box body The impact force applied to the 101 side is effectively reduced.

  In addition, by arranging the compressor 150 so as to avoid the position where the largest angular momentum is given among the angular momentum of the rotary door 113b, it is difficult for the impact when the rotary doors 113a and 113b are closed to be transmitted to the compressor. It is configured.

  Inventor's actual machine test using a 400-liter refrigerator (a weight of about several to 10 kg is put in the door pocket of the revolving door, the opening and closing speed of the revolving door is 6 to 12 times per minute, and the opening and closing frequency is several tens of thousands to 200,000. According to a test for evaluating the frequency with which the compressor 150 hits the hook, as compared with the refrigerator in which the compressor is disposed at the position where the largest angular momentum of the rotary door 113b is given. It has been confirmed that the frequency per hook decreases by about 50%.

  From the above, it is possible to suppress the hook contact of the compressor 150 due to an impact when the rotary doors 113a and 113b are closed, and abnormal wear or discharge caused by biting the generated chipping pieces by the hook contact. Fatigue fracture of the thin tube 171 can be avoided. Therefore, noise reduction can be achieved and a highly reliable refrigerator can be provided.

  In the present embodiment, when the refrigerator is viewed from the front, the ratio of the width of the left rotating door 113a to the width of the right rotating door 113b is about 4: 6. If the arrangement of the compressor 150 is avoided on the line 131, the same effect can be obtained even if the width ratio of the left and right revolving doors is changed.

  In this embodiment, drawer doors 115 a to 115 d for opening and closing the drawer chamber 108 are installed below the refrigerator compartment 107.

  Even when the drawer chamber 108 is pushed in, the impact is naturally transmitted to the box body 101 of the refrigerator. However, the compressor 150 is arranged away from the drawer chamber 108 so that the impact force when the drawer chamber 108 is pushed in is reduced. The configuration is difficult to be transmitted to the compressor 150, and the hook contact of the compressor 150 can be avoided.

  Furthermore, according to the present embodiment, the compressor 150 is installed in the recess 120 so that the reciprocating direction of the piston 165 is substantially parallel to the front surface 143 of the refrigerator.

  Here, the compressor 150 itself becomes a vibration generation source during operation. In general, vibrations generated from the reciprocating mechanism 174 include those caused by the rotational movement of the crankshaft 168 and frictional sliding during the reciprocating movement of the piston 165. Therefore, the vibration of the compressor 150 in the direction parallel to the reciprocating motion of the piston 165 (arrow P in FIG. 6) is relatively high.

  Based on this, in the present embodiment, the direction in which the impact force is transmitted when the rotary door is closed (the direction of arrow A in FIG. 6) and the reciprocating direction of the piston 165 (the direction of arrow P in FIG. 6). With the substantially vertical relationship, the direction in which the compressor 150 vibrates from the outside does not coincide with the direction in which the compressor 150 vibrates from the inside, so that it is possible to avoid the occurrence of frequent hitting of the shuttle due to the doubled amplitude of the compressor 150.

  Further, according to the present embodiment, the discharge thin tube 171 is formed so as to increase the rigidity in the substantially vertical direction by using the portion 171a extending in the direction perpendicular to the front surface 143 of the refrigerator. Yes.

  As a result, the portion 171a of the discharge thin tube 171 having high rigidity has a substantially parallel relationship with the direction (arrow A direction) in which the impact force is transmitted when the rotary doors 113a and 113b are closed. By making it difficult to deform, the swinging of the mechanism 174 (in the directions of arrows C1 and C2) when an impact is applied can be suppressed. Further, in order to secure a highly rigid portion 171a, if the space volume for meandering the discharge tubule 171 is insufficient, the same effect can be obtained even if the rigidity is increased by relatively increasing the thickness of the thin tube of the portion 171a. .

  On the other hand, the vibration of the mechanism 174 is transmitted to the refrigerator due to the relatively low rigidity of the portion of the discharge capillary 171 parallel to the reciprocating direction of the piston 165 (arrow P direction) and the height direction of the compressor 150. Can also be suppressed.

  According to the present embodiment, as shown in FIG. 6, the pitch between the legs 155a and 155b adjacent to each other in a direction substantially parallel to the collision direction A that collides with the box body 101 when the rotary door 113a is closed. Wm is formed to be longer than the pitch Wc between the support portions 152a and 152b adjacent to each other in a direction substantially parallel to the collision direction A.

  As a result, the pitch Wm between the legs 155a and 155b is increased, and the amplitude of vibration received from the outside in a direction substantially parallel to the collision direction A that collides with the box body 101 when the rotary door 113a is closed. Since the support portions 152a and 152b in the sealed container 152 are smaller than the leg portions 155a and 155b of the sealed container, the contact of the compressor 150 with the hook is suppressed. In addition, noise reduction can be achieved and a highly reliable refrigerator can be provided.

Be placed. The top of the top cover 226 is substantially flush with the top surface 218.

  According to the present embodiment, the radius of the arc 232a and the arc 232b of the opening / closing locus of the rotary doors 213a and 213b is smaller than that of the conventional single door type. Furthermore, by disposing the revolving doors 213a and 213b in two pieces and distributing the items stored in the revolving doors, the total weight including the weight of food stored in the weight per revolving door is apparently reduced.

The remaining switching room door 433, vegetable room door 434, and freezer room door 435 can be opened and closed forward and backward with the heat insulating box 421 by rail members 421b fixed to both sides of the heat insulating box 421 in each storage room. Connected.

  The lower hinge 437 below the refrigerator compartment door 432 is provided with a self-closing function part 437a and a deceleration function part 437b.

  The first position A at which the speed reduction function of the refrigerator compartment door 432 starts operating is the front opening 421a of the heat insulating box 421 and the bank on the opposite side of the rotation axis of the refrigerator compartment door 432 when the refrigerator compartment door 432 is closed. Between 432d, there is a space of about 100 mm to 150 mm.

  Similarly, the second position B where the deceleration function of the refrigerator compartment door 432 is released is the bank opening on the opposite side of the front opening 421a of the heat insulating box 421 and the rotational axis of the refrigerator compartment door 432 when the refrigerator compartment door 432 is closed. It is set to have a space of about 1 mm to 5 mm between 432d.

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

  First, the refrigerator compartment door 432 is fully opened and manually closed, and the refrigerator compartment door 432 is about 150 mm to 250 mm between the front opening 421a and the bank portion 432d on the opposite side of the rotation axis of the refrigerator compartment door 432. When it reaches a position having a space, the refrigerator compartment door 432 starts to close itself, and further closes between the front opening 421a and the bank portion 432d on the opposite side of the rotating shaft of the refrigerator compartment door 432 to about 100 mm to 150 mm. When the refrigerator compartment door 432 arrives at the first position A having a space, the speed reducing function portion 437b is activated, and the closing speed of the refrigerator compartment door 432 starts to be reduced.

  Furthermore, as the refrigerator compartment door is closed, the closing speed of the refrigerator compartment door 432 is gradually reduced, and approximately 1 mm to 5 mm between the front opening 421a and the bank portion 432d on the opposite side of the rotation axis of the refrigerator compartment door 432. When the second position B having the space is reached, the refrigerator door 432 is released from the deceleration function and is reliably closed.

  Further, the first position at which the deceleration function of the refrigerator compartment door 432 starts operating is the bank opening on the opposite side of the front opening 421a of the heat insulation box 421 and the rotation axis of the refrigerator compartment door 432 when the refrigerator compartment door 432 is closed. Although it is assumed that there is a space of about 100 mm to 150 mm between the refrigeration chamber 432d, it takes time to close the refrigeration chamber door 432 if the range in which the speed reduction function operates is wide, and as a result, the refrigeration chamber 428 that has been cooled with great effort Since the inside cold air escapes, the amount of power consumption increases or the stored item in the refrigerator compartment 428 deteriorates. Therefore, the range in which the deceleration function operates is limited to the heat insulating box 421 of the refrigerator door 432. It is better to be narrow in the range where the collision speed is sufficiently decelerated.

  However, when the refrigerator compartment door 432 is closed, the space between the front opening 421a of the heat insulating box 421 and the bank portion 432d on the opposite side to the rotation axis of the refrigerator compartment door 432 is narrowed, or the bank portion on the opposite side to the rotation axis. When the speed reduction function starts operation from the position where 432d enters the refrigerator compartment 428 further than the front opening 421a, the user's fingers and arms are sandwiched between the front opening 421a and the bank 432d opposite to the rotation axis. There is a risk that

  Therefore, in this embodiment, the user's fingers and arms are not caught in the space between the front opening 421a of the heat insulation box 421 and the bank portion 432d on the opposite side to the rotation axis of the refrigerator compartment door 432, The space is about 100 mm to 150 mm.

  In the present embodiment, the bank portion 432d is provided on the refrigerator compartment door 432. However, when there is no bank portion 432d, the space between the surface of the refrigerator compartment door 432 on the heat insulating box 421 side and the front opening 421a is set in each space. What is necessary is just to set it as a predetermined value range.

  The surface of the shelf 443 on the side of the heat insulation box 421 is substantially flush with the tip of the bank portion 432d, but the surface of the shelf 443 on the side of the heat insulation box 421 protrudes from the tip of the bank portion 432d toward the heat insulation box 421. In the case where the distance between the front opening 421a and the space between the front end of the shelf 432d and the surface of the shelf 443 on the heat insulating box 421 side is narrower, each predetermined value is set. The range may be used.

  When the refrigerator door 420 of the refrigerator 420 is a double door that is divided into left and right, the tip of the bank portion 432d opposite to the rotating shaft of the refrigerator door 432 on the open side and the heat insulating box 421 of the shelf 443 are provided. Each of the predetermined value ranges may be a space in which the distance between the heat insulation box 421 of the refrigerator compartment door 432 on the side in the closed position and the external surface on the opposite side is narrower.

  As described above, in the present embodiment, the refrigerator 420 has a speed reducing function that operates on the refrigerator compartment door 432, thereby reducing the impact force transmitted to the compressor 450 through the heat insulating box 421 when the refrigerator compartment door 420 is closed. By doing so, the hook contact of the compressor 450 can be suppressed, noise reduction can be achieved, and a highly reliable refrigerator can be provided.

FIG. 18 is a plan sectional view of the main part of the refrigerator in the fifth embodiment of the present invention, and FIG. 19 is a longitudinal sectional view of a compressor mounted on the refrigerator in the same embodiment.

  The refrigerator includes a machine room 510 provided at the rear of the top surface of the box body 501, a compressor 550 and a machine room fan 520 provided in the machine room 510, a high-pressure pipe 540 connected to the compressor 550, and a compressor. 550, a condenser (not shown), a decompressor (not shown), and an evaporator (not shown) are provided in this order, and a box body 501 is provided with a refrigeration cycle.

  Further, the uppermost storage chamber 507 is provided with a revolving door 513 so as to be rotatable through a hinge portion 512. The revolving door 513 is a single revolving door over almost the entire width of the box body 501 in the left-right direction. 513.

  The revolving door 513 opens and closes with the hinge portion 512 as a fulcrum, and the locus 532b of the end portion 513a opposite to the side on which the hinge portion 512 is provided has the largest opening and closing radius of the revolving door 513.

  Further, the compressor 550 is provided closer to the hinge portion 512 than the portion H corresponding to 1/2 of the full width G in the left-right direction of the box body 501.

  The compressor 550 is a reciprocating compressor that compresses refrigerant by reciprocating a piston (not shown) in the compression chamber 552 and the compression chamber 552 inside the sealed container 551. A discharge capillary 554 is provided to connect the compression element 553 provided to the high-pressure pipe 540 provided in the sealed container 551. The high-pressure pipe 540 and the discharge thin tube 554 are connected via a connection portion 555.

  As described above, the compressor 550 is disposed so that the compression chamber 552 is positioned on the side closer to the projection line on the hinge portion 512 side of the rotary door 513, and the left and right central axis I of the compressor is arranged. The end portion 553a of the compression element 553 located on the side facing the connecting portion 555 that connects the high-pressure pipe 540 and the discharge thin tube 554 is also located on the side closer to the projection line on the hinge portion 512 side of the rotary door 513. The compressor 550 is disposed in the front.

  In the refrigerator having the above-described configuration, the operation and action when the rotary door 513 is opened and closed will be described below.

  In the revolving door 513, the factor that affects the overall angular momentum is that the revolving door immediately before the collision between the revolving door 513 and the food stored in the door pocket (not shown) and the seal surface 517. The circumferential speed of 513 and the lateral width of the revolving door 513, that is, the radius 532b of the opening / closing locus of the revolving door 513. These govern the overall impact force applied to the box body 501 of the refrigerator when the gasket 516 and the seal surface 517 collide.

  Further, from the viewpoint of the distribution of angular momentum given to the rotary door 513, the circumferential speed increases as the point moves away from the hinge 512, which is the rotation fulcrum of the rotary door 513, and the angular momentum increases. In a state where food or the like is stored in the door pocket without being biased, normally, a distribution in which the angular momentum is maximized is exhibited at the end of the revolving door 513 opposite to the hinge 512.

  When the revolving door 513 is closed, a magnetic force acts between the permanent magnet built in the gasket 516 and the seal surface 517 formed of a magnetic material, and the gasket 516 comes into close contact with the seal surface 517.

  At this time, although the air pocket built in the gasket 516 absorbs the impact force to some extent, the impact force that cannot be absorbed is transmitted to the box body 501 of the refrigerator through the seal surface 517.

  Nowadays, the main capacity of the main refrigerator capacity band is 300L or more. As a result, as the refrigerator size increases, the radius arc 532b of the opening / closing locus of the revolving door 513 increases, and in addition, the amount of storage in the door pocket increases, The total weight is inevitably increased, and it is assumed that the impact force applied to the box body 501 when the rotary door 513 is closed increases synergistically.

  However, in the present embodiment, the compressor 550 is provided closer to the hinge portion 512 than the portion H corresponding to 1/2 of the full width G in the left-right direction of the box body 501, thereby closing the rotary door 513. At the time, by being largely separated from the projection line from the front side of the end portion 513a opposite to the side where the hinge portion 512 of the revolving door 513 having the largest impact force applied to the box body 501 of the refrigerator is provided. Because of the long dimension in the width direction, even in a type of revolving door where the distance from the fulcrum to the end on the side opposite to the fulcrum is large, the compressor is more on the projection line from the front of the largest dividing line in the angular momentum. By releasing 550, the impact force transmitted to the compressor through the refrigerator box body when the revolving door 513 is closed can be reduced, and the hitting of the compressor 550 can be suppressed and the noise can be reduced. It is possible to provide a high refrigerator.

  Note that the change in the width direction of the impact force when the rotary door 513 is closed is the opposite side of the hinge portion 512 in the case of a single door as in the present embodiment, and is generally at the end on the handle side. The portion is the largest because of the large turning radius, and the portion becomes smaller as it approaches the hinge portion 512. However, for convenience of taking in and out, the handle of the door pocket of the rotating door 513 is to store a heavy object such as a PET bottle beverage. In many cases, the impact force distribution in the actual use state becomes remarkable as the impact force decreases toward the hinge part 512 side.

  For this reason, in the space in the width direction of the machine room 510, the distances a and b in the width direction between the anti-hinge side space 510a and the hinge side space 510b, which are the left and right space spaces in which the compressor 550 is disposed, will be described. By setting the distance a of the space 510a to the distance b of the hinge-side space 510b, the central axis I in the width direction of the compressor 550 (container) corresponds to at least half of the full width G in the left-right direction of the box body 501. The portion closer to the hinge portion 512 side than the portion H can be set so that the impact force when the rotary door 513 is closed does not substantially affect the compressor 550.

  Further, if a portion H corresponding to 1/2 of the full width G in the left-right direction of the box body 501 is defined as a boundary line, if the entire compressor 550 is closer to the hinge portion 512 side than the boundary line, the impact at that point The force can be further reduced and the impact on the compressor 550 can be avoided.

  In the present embodiment, the compressor 550 is provided closer to the hinge portion 512 than the portion H corresponding to 1/2 of the full width G in the left-right direction of the box body 501, but the configuration inside the machine room 510 of the refrigerator Even when the compressor 550 extends to the opposite side of the hinge portion 512 from the portion H corresponding to ½ of the full width G of the box body 501 in the left-right direction, the compression chamber 552 is left and right of the box body 501. By providing closer to the hinge portion 512 than the portion H corresponding to ½ of the total width G in the direction, the reciprocating motion is performed in at least the compressor 550, so that the compression chamber 552 serving as a vibration generation source has an impact force. When the revolving door 513 is closed, it is compressed through the box body 501 of the refrigerator by separating it from the projection line from the front side of the end 513a opposite to the side where the hinge portion 512 of the revolving door 513 having the largest is provided. On machine 550 It is possible to reduce the Waru impact force, the kettle per the compressor 550 is suppressed, Hakare is quieter, it is possible to provide a highly reliable refrigerator.

  Similarly, even when the compressor 550 extends to the opposite side of the hinge portion 512 from the portion H corresponding to 1/2 of the full width G of the box body 501 in the left-right direction, the high-pressure pipe 540 and the discharge capillary tube The end portion 553a of the compression element 553 located on the side facing the connecting portion 555 that connects the 554 is provided closer to the hinge portion 512 than the portion H corresponding to 1/2 of the full width G in the left-right direction of the box body 501. In the compressor 550, the portion that is most likely to vibrate because it is farthest from the connecting portion 555 between the compression element 552 and the hermetic container 551 is further separated, so that the hook contact of the compressor 550 is suppressed and noise reduction is achieved. Therefore, a highly reliable refrigerator can be provided.

  Further, since the contact surface L between the leg 560 and the elastic member 561 of the compressor 550 of the present embodiment is located above the lower end surface 551a of the sealed container 551, the vertical center of gravity K of the compressor 550 is provided. The distance M between the leg 560 of the compressor 550 and the contact surface L of the elastic member 561 that elastically supports the leg 560 is the distance between the vertical center of gravity K of the compressor 550 and the lower end surface 551a of the sealed container 551. N is shorter than N.

  As a result, the amplitude of vibration when an external force is applied to the compressor 550 is such that the entire compressor 550 vibrates around the center of gravity where the vicinity of the center of gravity is the smallest and the vibration increases as the distance from the center of gravity increases. By positioning the contact surface L between the leg 560 and the elastic member 561 closer to the center of gravity, when an external force is applied to the compressor 550 from the refrigerator side, vibration of the compressor 550 as a whole can be reduced. As a result, vibration transmission to the refrigerator can be reduced, and a high-quality refrigerator free from unpleasant vibrations and noise generation due to vibrations can be provided.

  Further, the compressor 650 is disposed so as to avoid a projection line from the front to the rear of the dividing line 630 that is an end portion on the side facing the hinge portion 612 in the left-right direction of the rotary door 613. The dividing line 630 is the portion having the largest opening / closing track radius of the rotary door 613, and the compressor 650 is disposed avoiding the projection line from the front of the dividing line 630.

  Further, a heat insulating wall and a rotary door 613 that form the uppermost storage chamber 607 are located on the front side of the compressor 650.

  At this time, the impact force at the time of collision with the box body 601 when the rotary door 613 is closed and the influence on the compressor 650 are as described in the first embodiment.

  However, in the present embodiment, the uppermost storage chamber 607 provided in the box main body 601 is divided by a dividing line 630 in the width direction of the box main body 601, and the revolving door 613 rotates via the hinge portion 612. And a drawer-type drawer door 671, two doors are provided in the uppermost storage chamber 607, and the compressor 650 is disposed avoiding the projection line from the front of the dividing line 630. Therefore, the opening / closing locus of the revolving door 613 is smaller than that of a single door formed in the width direction, and two doors are used to distribute the items stored in the revolving door 613, so that each revolving door is per door. The total weight, which is the sum of the weight of the food and the stored food, is apparently lightened, the overall angular momentum applied to the rotary door 613 is reduced, and the impact force applied to the refrigerator box body 601 side is effective. Reduced To have.

  In addition, by arranging the compressor 650 so as to avoid the position where the largest angular momentum is given among the angular momentum of the rotary door 613, the impact when the rotary door 613 is closed is not easily transmitted to the compressor 650. It is said.
