Above case body 101, be provided with across the end face 118 of case body 101 and the back side 119 and to the recess 120 of refrigerating chamber 107 1 sides depression.In refrigerating chamber 107, be provided with a plurality of be used for taking in food etc. take in lattice 121.Recess 120 in the refrigerating chamber 107 the accommodation space 122a of the superiors one side of dividing by the superiors' lattice 122 and interior case 102 and the second layer accommodation space 123a that divides by second layer lattice 123 and the superiors' lattice 122 one side-prominent be convex.In addition, the lattice of the indoor diapire face 125 of preferred protuberance 124 and the superiors' lattice 122 bottom 122b is roughly on same horizontal plane.

Be provided with in the recess 120 with fixing end face lids 126 such as screws.Take in compressor 150, Machine Room fan 190, condensed device (not shown), drier (not shown) in the recess 120, discharging pipe arrangement 140, sucking the part of pipe arrangement 141 etc.In addition, compressor 150 avoid from about cut apart revolving door 113a, 113b cut-off rule 130 (with reference to Fig. 2, Fig. 3) the place ahead carry out on the projection line 131 (with reference to Fig. 3) of projection, and be positioned at the rear of revolving door 113b.In addition, the top of end face lid 126 and end face 118 cardinal principles at grade, the top 151 of compressor 150 is positioned at the position lower than end face 118.

In addition, for assembly operation and the service that improves freezer, and alleviate the closeness of pipe arrangement, thereby can see tubing connection portion from the rear.Therefore, watch from the freezer back side 119, formed discharge pipe 140a, suction line 141a go up the branch left and right sides and weld discharge pipe arrangement 140, suction pipe arrangement 141 on the side of the compressor 150 of (in front) on hand.

Below, utilize Fig. 4 that the structure of compressor 150 is described.Joint is the following container 172 of the mortar shape that forms of 2～4 millimeters rolled plate and the upper container 173 of the shape of falling the mortar by drawing and forming thickness, thereby welds whole bonding part formation closed container 152.In the inside of closed container 152, filling iso-butane (R600a) as cold-producing medium 153, storing machine oil 154 as mineral oil.And, the Machinery Ministry 174 that configuration is made up of electronic member 158 and compression element 163.Machinery Ministry 174 by spring 170 by elastic bearing at the support 160a that is fixedly installed on closed container 152 bottoms be fixedly installed between the support 160b of electronic member 158 lower ends.

Electronic member 158 is made of the below that is fixed on cylinder body group 159 and the stator that is connected with frequency converter drive circuit (not shown) 160 and the rotor 162 that is built-in with permanent magnet and is fixed on main shaft part 161 belows, thereby forms the motor that frequency converter drives usefulness.A plurality of operating frequencys according to comprising the operating frequency that is lower than the source power supply frequency drive by the frequency converter drive circuit.

Compression element 163 possesses the group 159 that forms cylinder body 164, the free bent axle 168 formed as the piston 165 in the through hole 175 of the cylinder body 164 of discharge chambe, by main shaft part 161 that is supported by the bearing 166 of cylinder body group 159 and core shift axial region 167 and the connecting rod 169 of binding core shift axial region 167 and piston 165 of reciprocally being embedded into.Rotatablely moving of bent axle 168 is converted into the reciprocating motion of piston 165.

Wherein, the vibration-direction of piston 165 (with reference to the arrow P among Fig. 6) is roughly parallel relation with the front 143 of freezer.That is when, making the vibration-direction of piston 165 be positioned at revolving door to close on the direction of the crash direction approximate vertical of bump case body.

In addition, increase and decrease takes place because of the reciprocating motion of piston 165 in the spatial volume of the discharge chambe 176 that forms in piston 165 and through hole 175.Like this, the cold-producing medium 153 in the closed container 152 is inhaled into from the suction inlet 178 of absorbing silencer 177, and is inhaled into and is compressed in the discharge chambe 176 by being arranged on the valve (not shown) that cylinder body covers 179 inside.Afterwards, from the exhaust silencer 180 that cylinder body group 159, forms,, be discharged to the discharge pipe arrangement 140 outside the closed container 152 through discharging tubule 171, being provided in the high press fit pipe discharge pipe of the conduct 140a in the closed container 152.

Discharging tubule 171 is that internal diameter is the steel pipe of 1.5mm to 3.0mm, by bending to L shaped it or U-shaped, use along the position 171a that extends with freezer front 143 approximate vertical directions morely, thereby the rigidity of the discharge tubule 171 of approximate vertical direction is strengthened.Promptly, elasticity connects compression element 163 and is provided in the discharge tubule 171 of the discharge pipe arrangement 140 of the high press fit pipe of conduct in the closed container 152, has the part 171a that forms on the direction of the crash direction almost parallel of bump case body 101 when closing with revolving door 113a.

The rigidity of the direction of the crash direction almost parallel of bump case body 101 when so just enhancing is closed with revolving door 113a.With the direction of this crash direction almost parallel on the part 171a that forms be not only by the parallel shape of rectilinear(-al), can certainly have curve or bend.In addition, the discharge pipe 140a that discharges tubule 171 and closed container 152 sentences elasticity at connecting portion 181 and is bonded together.

Below closed container 152, be fastened with a plurality of legs 155.By blocking the elastomeric element 156 that ends with each leg 155, make in the hole 157 of pin 127 movable embeddings (trip embedding) elastomeric element 156 on the recess 120 that is fixedly installed on freezer, fix the position with this.Moreover, and the front 143 of freezer is that spacing Wm between the leg 155 of parallel direction is longer than the diameter Wc of the closed container 152 of same parallel direction.

Below, the impulsive force when closing revolving door 113a, 113b and during case body 101 bumps describes the influence of this compressor 150.

In addition, circular arc 132a be with revolving door 113a in the switch track of distal end of hinge 112 opposite sides, circular arc 132b be with revolving door 113b in the switch track of distal end of hinge 112 opposite sides.

Generally speaking, the amount as the trend of representing rotary body has angular momentum.Angular momentum is proportional with quality, circumferencial direction speed, radius of turn respectively.That is to say, when closing revolving door 113a, 113b, the angular momentum that is applied on revolving door 113a, 113b is big more, revolving door 113a, 113b and accept revolving door 113a, 113b one side, and promptly the impulsive force that is produced during sealing surface 117 bumps of case body 101 becomes big.In addition, impulsive force with front 143 vertical direction of freezer on exert an influence.

If with revolving door 113b is that example describes, so, the factor that influences overall angular momentum be revolving door 113b and the gross mass that is accommodated in food in the door pocket 114 etc., with sealing surface 117 bumps before circumferencial direction speed, revolving door 113b horizontal wide of revolving door 113b, being the switch track of revolving door 113b, is the radius of circular arc 132b.These factors when pad 116 and sealing surface 117 bumps dominating role in total impulsive force of the case body 101 of freezer.

In addition, from the viewpoint of the distribution that acts on the angular momentum on the revolving door 113b, far away more from the hinge 112 as the pivot point of revolving door 113b, circumferencial direction speed is big more, and angular momentum increases.If with the not liftoff state that is accommodated in the door pocket 114 partially such as food, so, generally, be with revolving door 113b in the end angular momentum of hinge 112 opposite sides be maximum this distribution.

In case close revolving door 113b, so, magneticaction is located at the permanent magnet in the pad 116 and uses between the sealing surface 117 of magnetic formation, so pad 116 closely contacts with sealing surface 117 in quilt.At this moment, though in be located at airbag in the pad 116 and absorb to a certain degree impulsive force,, the impulsive force that can't absorb fully passes to the case body 101 of freezer by sealing surface 117.

Now, the range of capacity of main flow freezer all is more than the 300L basically.So can infer, increase along with the freezer size, radius as the circular arc 32 of the switch track of revolving door 13 becomes big, and, because the amount of taking in of door pocket 14 increases, the gross weight that adds the revolving door 13 of weight such as the product of taking in must increase, and when revolving door 13 was closed, the impulsive force that acts on the case body 1 will increase exponentially.

Below, the system of the unusual collision of compressor is described according to Fig. 6.Formed discharge pipe 140a and suction line 141a weld with the discharge pipe arrangement 140 that forms in the freezer side, suction pipe arrangement 141 respectively in the side of closed container 152.In addition, the leg 155 that is fixed on closed container 152 belows is fixed on the face that the is provided with 120a of recess 120 by pin 127.This mode can be described as the closed container 152 that constitutes compressor 150 shells and is in the state that is limited by freezer.Therefore, if owing to closing revolving door 113b from the impact (arrow A among the figure) of front 143 make freezer forwards, backwards direction shake (arrow B 1 direction, B2 direction among the figure), so, closed container 152 with by the mode of freezer tractive equally forwards, backwards direction shake.

On the other hand, in the inside of the compressor 150 of the moment that is applied in impact, because of elastic bearing (with reference to Fig. 4), on the inertia force surface along the B2 directive effect on the Machine Room of being formed at compression element 163 and electronic member 158 174.And along with the vibration of closed container 152, the support 160a that is fixedly installed on closed container 152 bottoms is along arrow B 1 direction displacement.In addition, by with the discharge tubule 171 that is fixedly installed on the discharge pipe 140a welding on the closed container 152, traction force along arrow B 1 directive effect in Machinery Ministry 174, so, in spring 170, produce distortion.Afterwards, utilize the elastic recovering force of spring 170 and discharge tubule 171, Machinery Ministry 174 is the centrifugal rotation of circular-arc arrow C 1, C2 at center along the connecting portion 181 of discharging the discharge pipe 140a of tubule 171 and closed container 152 with joint.

In embodiment 1, central shaft 150a with the left and right directions of compressor 150 is the boundary, make and be provided with discharge tubule 171 a side in opposite directions the position of the end 150b of the compression element of a side avoid from about cut apart on the projection line of front projection of cut-off rule 130 of revolving door 213b, promptly be configured in the position of not blocking on the projection line.

Moreover, cut-off rule 130 be with comprise with revolving door 113b in the in the past direction rear projection line that carries out projection of side walls of revolving door 113b of above-below direction of end of hinge 112 opposite sides.

Like this, dwindle the switch orbital radius of revolving door 213b, and totally dwindle the angular momentum of revolving door 213b.Simultaneously, avoid on the projection line from the place ahead of the cut-off rule 130 of maximum within the angular momentum of revolving door 213b, the connecting portion 181 away from Machinery Ministry of being made up of compression element 163 and electronic member 158 and closed container 152 disposes in compressor 150 at least.Like this, because away from the easy part of vibration significantly, therefore, a kind of unusual collision that can control compressor 150 can be provided, realize quietization and the high freezer of reliability.

Since this closed container 152 shake centrifugal rotation with Machinery Ministry 174, Machinery Ministry 174 contacts with the inwall of closed container 152, thereby so-called unusual collision (metal bump) takes place.

But, in embodiment 1, from refrigerating chamber 107 the door 105 roughly in the middle of, on the cut-off rule of cutting apart according to 4: 6 ratio 130, the mode of opening with both sides to the left and right is provided with two fan revolving door 113a, 113b, simultaneously, avoid being provided with compressor 150 from the projection line 131 in cut-off rule 130 the place aheads.

Like this, the radius of the circular arc 132a of the switch track of revolving door 113a, 113b and circular arc 132b diminishes with comparing originally.And, two fan revolving door 113a, 113b are set, to disperse to be accommodated in the article of taking in the revolving door, therefore, gross weight from the weight of the weight that alleviates every fan revolving door in appearance and the food that is contained etc., dwindle the total angular momentum that acts on each revolving door 113a, the 113b, thereby reduce impulsive force effectively case body 101 1 sides of freezer.

And, dispose compressor 150 owing to avoid the position of the maximum angular momentum within the angular momentum of revolving door 113b, therefore, the impact when closing revolving door 113a, 113b is difficult to be communicated to compressor.

The inventor uses capacity to test as the freezer of 400L.As experimental condition, for example under putting into the state of the hammer about number～10kg in the door pocket, rotation closes revolving door.The switching speed of revolving door is 1 minute 6～12 times, and the switch number of times is tens thousand of～200,000 time.At this moment, assessment compressor 150 collides the number of times frequency of (metal bump) unusually.Obtain confirming that according to this result of the test set up the freezer of compressor with the position that maximum angular momentum within the angular momentum of revolving door 113b is acted on and compare, the number of times frequency of unusual collision reduces about 50%.

As seen from the above description, can control the unusual collision of the compressor 150 that the impact when closing revolving door 113a, 113b causes.Simultaneously, can avoid nipping because of colliding the fatigue fracture that the bits sheet that is generated produces inordinate wear, discharges tubule 171 unusually.Therefore, can realize quietization, provide a kind of reliability high freezer.

In addition, in embodiment 1, watch freezer from the front, the horizontal wide ratio of the revolving door 113b on the horizontal wide and right side of the revolving door 113a in left side approximately is 4: 6.But, if avoid disposing compressor 150 on the projection line 131 from cut-off rule 130 the place aheads, so, even the width ratio of the revolving door about change also can obtain same effect.

Wherein, in embodiment 1, below refrigerating chamber 107, be provided with and be used for the sliding door 115a to 115d of switch pull chamber 108.

When promoting pull chamber 108, impact the case body 101 that also can pass to freezer certainly, still, compressor 150 is set at the position away from pull chamber 108.Like this, adopt the impulsive force when promoting pull chamber 108 to be difficult to pass to the structure of compressor 150, and can avoid the unusual collision of compressor 150.

And according to embodiment 1, the mode with front 143 almost parallels of the vibration-direction of piston 165 and freezer is provided with compressor 150 in recess 120.

Herein, the compressor 150 own on-stream vibration generation source that become.Generally speaking, as the vibration that produces from shuttle Machinery Ministry 174, can enumerate rotatablely moving or the caused vibration of friction slip the during reciprocating motion of piston 165 of bent axle 168, but wherein the reciprocating influence with piston 165 is bigger especially, therefore, higher with the vibration of the compressor 150 of reciprocating motion (among Fig. 6, the arrow P) parallel direction of piston 165.

Based on this point, in the present embodiment, the direction that impulsive force when closing revolving door is communicated is (among Fig. 6, the arrow A direction) and the vibration-direction of piston 165 (among Fig. 6, the arrow P direction) be roughly vertical relation, like this, owing to make the direction of the direction of compressor 150 vibrations and vibration internally inconsistent from the outside, so, can avoid the doubled in amplitude of compressor 150 and cause again and again taking place unusual collision.

In addition, according to embodiment 1, discharge tubule 171 and utilize more at the side upwardly extending position 171a vertical with the front 143 of freezer, therefore, the rigidity of approximate vertical direction strengthens.

Like this, because the direction (arrow A direction) that the impulsive force of the position 171a of the high discharge tubule 171 of rigidity when closing revolving door 113a, 113b is communicated is roughly parallel relation, therefore, the strain that suppresses the arrow A direction, control is applied in the centrifugal rotation (arrow C 1, C2 direction) of the Machinery Ministry 174 when impacting.Be the position 171a that guarantees that rigidity is high, discharge tubule 171 and crawl under the situation of spatial volume deficiency of (complications) configuration making,, therefore, also can obtain same effect even improve rigidity owing to make the tubule wall thickness of position 171a thicker.

The rigidity at the position by making the discharge tubule 171 parallel with the short transverse of the vibration-direction (arrow P direction) of piston 165 or compressor 150 is lower, and the vibration that so also can suppress Machinery Ministry 174 is communicated to freezer.

In addition, a feature of embodiment 1 is, as shown in Figure 6, the crash direction A of bump case body 101 is roughly the spacing Wm between leg 155a, the 155b adjacent on the parallel direction when closing with revolving door 113a, than long at the spacing Wc that is roughly between support 152a, the 152b adjacent on the parallel direction with crash direction A.

So just can enlarge the spacing Wm between leg 155a, the 155b.The crash direction A of bump case body 101 roughly becomes the suffered vibration amplitude from the outside on the parallel direction when closing with revolving door 113a, compare with foot section 155a, the 155b of closed container, support 152a, 152b in the closed container 152 are littler.So,, therefore, by the centrifugal rotation of inhibition Machinery Ministry, thereby can realize quietization, and can provide a kind of reliability high freezer owing to suppress the unusual collision of compressor 150.

Figure 18 is the section plan of the related freezer major part of embodiments of the present invention 5, and Figure 19 carries the profilograph of the compressor in the related freezer of same embodiment.

Freezer comprises: be provided in the end face rear of case body 501 Machine Room 510, be provided in compressor 550 and Machine Room fan 520 in the Machine Room 510.In addition, in case body 501, have high press fit pipe 540 that outfit in turn is connected with compressor 550, compressor 550, condensed device (not shown), pressure reducer (not shown), evaporimeter (not shown) and the freeze cycle that forms.

In addition, in the storeroom 507 of the superiors, be equipped with the revolving door 513 that rotates freely by hinge portion 512.Revolving door 513 is to form 1 fan revolving door 513 across the roughly whole width of the left and right directions of case body 501.Revolving door 513 is that fulcrum carries out switch with hinge portion 512, with the track 532b of the end 513a of the opposite side of a side that hinge portion 512 is housed in, the switch orbit radius of revolving door 513 is maximum.

In addition, compressor 550 is provided in 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 near a side of hinge portion 512.Compressor 550 is in the inside of closed container 551, thereby the piston (not shown) moves back and forth the reciprocating motion type compressor of the compression of carrying out cold-producing medium in discharge chambe 552 and discharge chambe 552.It also possesses: connect compression element 553 that possesses discharge chambe 552 and the discharge tubule 554 that is provided in the high press fit pipe 540 in the closed container 551.High press fit pipe 540 and discharge tubule 554 link together by connecting portion 555.

Like this, be positioned near the position of the projection line of hinge portion 512 1 sides of revolving door 513 with discharge chambe 552 and set up compressor 550.Central shaft I with the left and right directions of compressor is the boundary, be positioned at the connecting portion 555 that is connected high press fit pipe 540 and discharges tubule 554 in opposite directions the end 553a of the compression element 553 of a side be positioned at too near the position of the projection line of hinge portion 512 1 sides of revolving door 513 and set up compressor 550.

Below, the operational circumstances during revolving door 513 switches is described in the freezer of above-mentioned structure.In revolving door 513, the factor that influences total angular momentum be revolving door 513 and the gross mass that is incorporated in food in the door pocket (not shown) etc., with the bump of sealing surface 517 before, the horizontal wide of the circumferencial direction speed of revolving door 513, revolving door 513 is the radius 532b of the switch track of revolving door 513.These factors are the total impulsive force on the case body 501 of dominating role at freezer when pad 516 and sealing surface 517 bumps.

In addition, from being applied to the viewpoint of the distribution of angular momentum on the revolving door 513, leave the hinge 512 as the pivot point of revolving door 513 more, circumferencial direction speed is big more, and angular momentum increases.If, so, generally, be following this distribution the not liftoff state that is accommodated in the door pocket partially such as food, in revolving door 513 and distal end hinge 512 opposite sides, angular momentum maximum.

If close revolving door 513, so, magneticaction is located at the permanent magnet in the pad 516 and uses between the sealing surface 517 of magnetic formation in quilt, so pad 516 is close together with sealing surface 517.

At this moment, though in be located at airbag in the pad 516 and absorb to a certain degree impulsive force,, the impulsive force that can't absorb fully passes to the case body 501 of freezer by sealing surface 517.

Now, the normal capacity scope of main flow freezer all is more than the 300L basically.So just can infer, increase along with the freezer size, radius as the circular arc 532b of the switch track of revolving door 513 becomes big, and, because the amount of taking in of door pocket increases, the gross weight that adds the revolving door 513 of the product of taking in etc. must increase, and when revolving door 513 was closed, the impulsive force that is applied on the case body 501 increased exponentially.

In embodiment 5, compressor 550 is provided in than 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 and near hinge portion 512 1 sides.Like this can be greatly away from projection line when closing revolving door 513 to the front of the end 513a of the opposite side of the hinge portion of being equipped with 512 1 sides of the revolving door 513 of the impulsive force maximum of the case body 501 of freezer on.Like this owing to laterally have long size, therefore, though at fulcrum to the big revolving door of the distance of the end of anti-fulcrum one side, the projection line of compressor 550 maximum cut-off rule front within the angular momentum is left.When closing revolving door 513, not only can reduce the impulsive force that passes to compressor by the case body of freezer, and can control the unusual collision of compressor 550, realize quietization, thereby can provide a kind of reliability high freezer.

In addition, as described in enforcement mode 5, under the situation that a door is set, generally speaking, because it is big to be configured in the radius of turn of end of handle one side of hinge portion 512 opposite sides, therefore, the horizontal variation of the impulsive force when closing revolving door 513 is also maximum.On the contrary, along with diminishing near hinge portion 512 impulsive forces.For conveniently picking and placeing food, adopt in handle one side of the door pocket of revolving door 513 taken in design as weight things such as PET bottled drinks more.For the distribution of implementing the impulsive force under the user mode, the closer to hinge portion 512 1 sides, the minimizing degree of impulsive force is obvious more.

Therefore, in horizontal space, Machine Room 510, the relation of horizontal horizontal distance b apart from a and hinge side space 510b of anti-hinge side space 510a that has disposed the space, the left and right sides of compressor 550 is set as a＜b, like this, the horizontal central shaft I of compressor 550 (container) is at least than 1/2 the more close hinge of section H portion 512 1 sides of the whole width G of the left and right directions that is equivalent to case body 501.Like this, just can make the impulsive force when closing revolving door 513 be controlled at the degree that in fact can not influence compressor 550.

And, with 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 as the line of demarcation, close hinge portion 512 1 sides by whole compressor 550 is compared with this line of demarcation, like this, the impulsive force of this point can be further be reduced in, and influence can be avoided compressor 550.

Moreover a feature of embodiment 5 is: compressor 550 is provided in compares with 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 and near hinge portion 512 1 sides.Structure from 510 inside, Machine Room of freezer,, under the situation that an opposite side of the hinge portion 512 that compares with 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 is extended, also discharge chambe 552 is provided in 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 near a side of hinge portion 512 at compressor 550.Owing in compressor 550, move back and forth at least, therefore, make the discharge chambe 552 that becomes vibration generation source away from the projection line of the front of the end 513a of the opposite side of a side of the hinge portion 512 of being equipped with of the revolving door 513 of impulsive force maximum on, like this, when closing revolving door 513, not only can reduce the impulsive force that is communicated to compressor 550 by the case body 501 of freezer, and, can control the unusual collision of compressor 550, realize quietization, thereby provide a kind of reliability high freezer.

Compressor 550 might be compared with 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 and extend to an opposite side of hinge portion 512.But, since will be positioned at the connecting portion 555 that is connected high press fit pipe 540 and discharge tubule 554 in opposite directions the end 553a of the compression element 553 of a side be provided in 1/2 section H of the whole width G of the left and right directions that is equivalent to case body 501 and compare and close hinge portion 512 1 sides, therefore, in compressor 550, with the connecting portion 555 of compression element 552 and closed container 551 from farthest, therefore, the easy further away from each other significantly part of vibration, so just can suppress the unusual collision of compressor 550, realize quietization, thereby can provide a kind of reliability high freezer.

In addition, the contact-making surface L of the leg 560 of the compressor 550 of embodiment 5 and elastomeric element 561 compare with the lower surface 551a of closed container 551 and be positioned at the top.Short apart between the lower surface 551a of the center of gravity K of the above-below direction of M ratio piston compressor 550 and closed container 551 between the contact-making surface L of the leg 560 of the center of gravity K of the above-below direction of compressor 550 and elastic bearing compressor 550 and the elastomeric element 561 of leg 560 apart from N.

Like this, the amplitude of the vibration when external force acts on compressor 550 is minimum near center of gravity, and along with becoming big away from the center of gravity vibration, whole compressor 550 is vibrated around center of gravity.Like this, be positioned at center of gravity, just can in external force when freezer one side acts on the compressor 550, reduce the vibration of whole compressor 550 near compressor 550 by the contact-making surface L that makes leg 560 and elastomeric element 561.And, can also reduce the vibration that is conveyed to freezer, thereby a kind of high-quality freezer that does not have the noise that uncomfortable vibration and vibration cause can be provided.
