Should outstanding dimension D 2, more exactly, be width dimensions W2 from the revolving door hinge portion 31,32 that deducts each revolving door 11,12 fulcrum to the hinge Outboard Sections of hinge side end face 11b, 12b apart from the size behind the d.This hinge Outboard Sections apart from d, be typically thickness about 1/2 of adiabatic wall, for example be 1.5cm.

Therefore, be the occasion of 30cm at the width dimensions W2 of revolving door, the maximum of revolving door 11,12 is given prominence to dimension D 2, for example becomes 28.5cm.At this moment, if more than depth dimension D 1 57cm of refrigerator, then the outstanding dimension D 2 of the maximum of revolving door 11,12 becomes below 1/2 of depth dimension D 1 of refrigerator.

If, even about revolving door 11,12 between width dimensions be provided with some difference, if depth dimension D 1 compares greatly with the width dimensions W1 of refrigerator, the maximum of revolving door is given prominence to below 1/2 of depth dimension D 1 that dimension D 2 also becomes refrigerator.

Like this, in slender type refrigerator of the present utility model, revolving door is arranged to middle opening type, and the width dimensions of the revolving door about making becomes about equally or gap is little.

Therefore, owing to can reduce forwards outstanding dimension D 2,, can relax the restriction that the space is set significantly to refrigerator so can obtain the interval between cupboard frame and the structure etc. of taking in of the place ahead of refrigerator and other less.In addition, even there is not other the occasion of taking in cupboard frame and structure etc., also can make the current of the people that do not hinder in the zone in refrigerator the place ahead.

Expression is opened about 90 ° with the revolving door about refrigerator 11,12 in the vertical view of Fig. 5～6 and the side view, and will be positioned at the form of drawer type accommodating container when forwards pulling out to greatest extent of its below.

Each drawer type door 22～25, the guide rail mechanism 28 about utilization just can forwards slide with the accommodating container 26 at rear.In addition, in illustrated embodiment, the handle 27,29 of horizontal direction is installed in the upper end of the outside of vegetable compartment usefulness drawer type door 22 and refrigerating chamber usefulness drawer type door 25.

Shown in Fig. 5～6, when drawer type door 22～25 was pulled out to greatest extent, vegetable compartment projected to the forefront with drawer type door 22 in them.And free end 11a, the 12a of revolving door 11,12 also are being positioned at the rear of vegetable compartment with drawer type door 22 when the forefront is outstanding.That is, the outstanding dimension D 2 of the maximum of revolving door 11,12 is littler than the outstanding dimension D 3 of drawer type door 22 maximum forwards.

In addition, as shown in Figure 6, in more detail, ice-making compartment door and temperature are switched the chamber with drawer type door 23～24, are positioned at the position of vegetable compartment with the thickness size of the door at drawer type door 22 rears, and refrigerating chamber is positioned at their centre with drawer type door 25.And free end 11a, the 12a of revolving door 11,12 also are being positioned at the rear of temperature switching chamber with drawer type door 24 when the forefront is outstanding.That is, the maximum of revolving door 11,12 is given prominence to dimension D 2, and is littler than the outstanding dimension D 4 of the drawer type door 24 that is positioned at rear.

Therefore,, drawer type door 22～25 is drawn out to roughly space to greatest extent, just can easily revolving door 11,12 be opened and closed, also can carry out the taking-up of collecting article as long as have in the place ahead of refrigerator 10.

In the concrete example of dimensional structure, the depth size of the refrigerator 10 that internal volume is 415 liters (to the size of the shop front) D1 is that 67cm, height dimension are 173cm; The outstanding dimension D 2 of the maximum of revolving door 11,12 is 25cm; The outstanding dimension D 3 of the maximum of drawer type door 22 is 35cm.

Therefore, when vegetable compartment is pulled out to greatest extent with drawer type door 22, even with the wall in the place ahead or take in roughly butt of cupboard frame, and free end 11a, the 12a of revolving door 11,12 between outstanding position, forefront, the interval of the 10cm that also has an appointment.Therefore, can easily be rotated the taking-up of putting into of door 11,12 opening and closing operations and collecting article.

In Fig. 3, expression opens to revolving door 11,12 does not all have the angle of any obstacle, the i.e. state of maximum open angle extremely with left and right sides angle same to the taking-up of putting into of common large-scale collecting article.

From viewpoint easy to use, door goods basket member 14, capacity is quite big, and the size of depth direction is also quite big.The size of the refrigerator depth direction of door goods basket member 14, for example be refrigerating chamber 51 the depth size 30～40%.

But, about the state of revolving door 11,12 after for example opening to about 135 °, between the front end of 11,12 goods basket members 14 of two revolving doors, be formed with collecting article and put into the sufficient interval of taking out usefulness.In addition, the place ahead of the shelf 4 in refrigerating chamber 51 offers and puts into the sufficient space of taking out operation usefulness.Also just can not between shelf 4, insert as not putting into taking-up under this state, and the taking-up of putting into of common large-scale collecting article is not being produced obstacle fully.

Under the state of Fig. 3, the relative size Wmax of the left and right directions of revolving door 11,12 comprises handle 13 outstanding size, is 1.6～1.8 times of width dimensions W1 when closing.In addition, at this moment, revolving door 11,12 is the outstanding size W3 in the direction outside to the left and right, is 0.3～0.4 times of width dimensions W1 when closing.

Make 60cm as the width dimensions W1 with refrigerator, then putting into the relative size Wmax that takes out the easy revolving door of opening to greatest extent 11,12 is 96～108cm, and the size W3 that direction is outstanding is 18～24cm to the left and right.That is, relative size Wmax is below 1.8 times of width dimensions W1 of refrigerator.Therefore, from refrigerator 10 front space direction to the left and right,, just can carry out the taking-up of putting into easily to receiving room as long as the width dimensions of this degree is arranged.

In contrast to this, if the revolving door of refrigerating chamber is made the single open-type that a fan is only arranged, when opening about 135 °, a certain to the left and right side is outstanding to be of a size of above-mentioned about 2 times.

In the hinge portion 31,32 of revolving door 11,12,, revolving door 11,12 is opened to more than the state shown in Figure 3 by being provided with the stopper mechanism of restriction open angle.Thus, can prevent that revolving door 11,12 from too opening and hinder current situation.In addition, the occasion that for example has the meat safe frame etc. of glass door to place on the next door of refrigerator can prevent that revolving door 11,12 from colliding consumingly to it.

In addition, be arranged on the occasion of the corner in kitchen, can only open to about 90 ° occasion, can make right-hand revolving door 12 is opened to 180 ° or state more than it at the revolving door 11 of for example left at refrigerator 10.

Open 180 ° or its outstanding to greatest extent size to right-hand outside when above at right-hand revolving door 12, be generally revolving door 12 the left and right directions size, be refrigerator width dimensions W1 about 1/2.More exactly, be the size of having considered from the fulcrum of hinge portion 32 to the distance of hinge side end face 12b, roughly the same with the above-mentioned outstanding dimension D 2 of maximum forwards.

If the slender type refrigerator in the past of opening type when revolving door is opened 180 °, to right-hand outstanding size, does not roughly become identical with the width dimensions of refrigerator in the middle of revolving door not being made.Width dimensions at refrigerator is the occasion that 60cm, the hinge outside are of a size of 2cm, becomes 58cm to right-hand outstanding size.In addition, the width that the space of usefulness is taken out in required putting into for the front side of refrigerator be 118cm (=60cm+58cm).

In the hinge portion 31,32 of revolving door 11,12,, revolving door 11,12 is not opened to more than the state shown in Figure 2 by being provided with the stopper mechanism of restriction open angle.For example, the occasion that has the meat safe frame etc. of glass door to place on the next door of refrigerator can prevent that revolving door 11,12 from colliding and situation that glass door or feeder are smashed.

For in hinge portion 31,32, stopper mechanism being set, according to the situation that the place is set of refrigerator 10, can about revolving door 11,12 between the angle that can open is provided with difference.For example, also the desirable maximum open angle of the revolving door 11 of left can be made 90 °, and the desirable maximum open angle of right-hand revolving door 12 is made 180 °.

In the embodiment of above explanation, to below the revolving door of middle opening type, the structure that is provided with drawer type door 22 is described, but also can be the structure that only is provided with 1 pair of revolving door.This occasion is because of reducing the door number, so can reduce the manufacturing cost of door.

In addition, in above-mentioned example, to about the size of revolving door 11,12 structure that makes left and right sides approximate same size be described, different situations describes about below the width dimensions with revolving door 11,12 being made.

In this occasion, since the width dimensions (W2max) of the revolving door of a side that width dimensions is big make refrigerator depth size (D1) 1/2 below or the outstanding size that makes when any described drawer type door is forwards pulled out to greatest extent of revolving door forwards outstanding size to greatest extent when opening of the big side (W2max) of width dimensions little, so can obtain and the same effect of aforementioned example.

a＝G·b/F ……(1)

Wherein, a, b represent the size of the part shown in Figure 10,11.

Here, the weight of refrigerator and position of centre of gravity, taking specified internal volume is the mean value of the leptosomatic refrigerator of 450 liters of specifications.In addition, for each child's weight,, adopt the average weight (putting down into the health care survey of 13 annual schools) of primary school's 6 classmans according to Japan as big child's body weight.So,

G：87kg～90kg

B:278mm (horizontal range) from refrigerator framework front

F:40.1kg * 2 people=80.2kg

The width dimensions a (W2 of Fig. 7) of the revolving door 11,12 under this condition becomes,

a＝G·b/F＝87×278/80.2～90×278/80.2＝301.6～312.0(mm)

Therefore, as long as in advance the width dimensions a of revolving door 11,12 is made below the 312.0mm, prevent overturning surely with regard to one.

In addition, in aforementioned calculation, be that the refrigerator of other embodiment of 450 shown in Fig. 7～9 upgradings is calculated, but the refrigerators of other refrigerator of level below it, for example 400 liters or 350 upgradings are not had big difference yet.

Then, use the ideograph with the similar Figure 11 of Figure 10, the front end 61a with support foot 61 is arranged on front 5a with refrigerator framework 5 is positioned at same plane or is positioned at more the size design condition of the situation at rear and carry out tentative calculation.

According to Figure 11, with above-mentioned same, if the condition of FM=GM is represented with numerical expression, then,

L·Fsinα＝e·Gsin β

Wherein, sin α=(a-X)/and L, sin β=(b+X)/e

∴ FL (a-X)/L=Ge (b+X)/e (establishing G/F=c)

Here, G, b, F are same with the occasion of above-mentioned (1) formula, with the numerical value substitution shown in above.

In addition, X is the outstanding size from the front end 61a of the front 5a support foot 61 forwards of refrigerator framework 5.That is to say that X is so long as negative value, even the front end 61a of support foot 61 is configured in the front 5a same level with refrigerator framework 5 or, also can makes enough stable for overturning than its rear more.

∴X＝(a-278c)/1+c ……(2)

Then, the width a (W2) that X is made the revolving door of using below the 0mm 11,12 is calculated.

Because c=G/F,

In the occasion of 87/80～90/80=1.08～1.12 a=300mm,

X＝{(300-278×1.08)/1+1.08}

～{(300-278×1.12)/1+1.12}

＝-0.12～-5.36(mm)

Equally, change a value and when calculating, as shown in the table.The weight of refrigerator is the occasion of 87kg and calculates for the occasion of 90kg.

The reckoning of the assigned position X of [table 1] support foot

The a value	300mm	305mm	312mm	325mm
					87kg	-0.12	+2.29	+5.56	+11.90
90kg	-5.36	-3.00	+0.30	+6.43

As above shown in the table, as long as the width of clamshell doors is 300mm, because that the X value becomes is negative, so can make the support foot (forward foot in a step) 61 in the place ahead be positioned at the inboard of the front 5a of refrigerator framework 5 (cabinet), if during 305mm, just support foot 61 must be configured in the place ahead of the front 5a of refrigerator framework 5 (cabinet).Therefore, also can make steadily of centre of gravity in order to make under impossible mal-condition as described above, the support foot in the place ahead (forward foot in a step) 61, just outstanding from the front 5a of refrigerator framework 5, might produce harmful effect to outward appearance, and can not save the cost that is used for installation component.

For above-mentioned tentative calculation, can attempt carrying out following vague generalization.

Position of centre of gravity b (278mm) in above-mentioned concrete example is that fore-and-aft direction dimension D 0 (615mm) in the refrigerator framework is multiplied by the numerical value after 0.45.It is also roughly the same for other the longitudinal type refrigerator of specified internal volume more than 300 liters that this numerical value is considered to.

In addition, for the weight G of refrigerator, can think imaginary peak load F usually 1.1 times.As long as specified internal volume is more than 300 liters, the weight G of refrigerator is at least 66kg, though this occasion with 60kg as imaginary peak load F, should be also without any problem.

So, about the size W2 (a) of revolving door 11,12, so long as general 0.45 * 1.1 times of the fore-and-aft direction dimension D 0 of refrigerator framework, promptly about 1/2 or below it, just can get rid of the possibility of overturning.

If be described with numerical expression, just as below.

If it is just enough to satisfy a≤Gb/F that makes after Fa≤Gb is out of shape,

Because be Gb/F=1.1 * 0.45 * D0=D0/2,

As long as so it is just passable to satisfy a≤D0/2.

But the weight of refrigerator preferably is more than the 80kg to be good more than the 70kg.This occasion, as with the explanation of Figure 10～11, by with about the width dimensions W2 (a) of revolving door 11,12 make below the 30cm, can give the very high overturning performance that prevents.

The left and right sides width dimensions W1 that apartment building is used etc. is so long as the leptosomatic refrigerator about 60cm, can make door-opening type about the width dimensions W2 (a) of revolving door make equally, can make below the 30cm easily.

Then, use the part amplification view of Figure 12 that variation of the present utility model is described.In variation, the castor 62 at the support foot in the place ahead 61 and its rear is installed in the bight of refrigerator framework 5 by simple installation component 65.In addition, be provided with the front cover consistent 66 in its place ahead with the outside of drawer type door 25.

Even in this variation, and to compare from the outstanding situation of the front 5a of refrigerator framework, it is simple that the structure of installation component becomes.In addition, cover 66 even without also can, and see also and can freely be provided with from the viewpoint of design aspect.Therefore, can improve the effect of design concept.In illustrated embodiment, that the former configuration one-tenth of cover 66 is consistent with the front of drawer type door 25.
