The B-B line cutaway view of Fig. 3 presentation graphs 1.Refrigerating-chamber door 6a is that the center is supported rotatably freely with back shaft S1.The storage means 6a1 for the translucent resin forming door of bag shape of the beverage of packing into etc. is set on refrigerating-chamber door 6a and to the inside highlightedly.Be provided with the rotation partition member 6a2 that active force and guiding by torsion-coil spring joltily constitute freely in the inside of refrigerating-chamber door 6a.

This rotation partition member 6a2 when refrigerating-chamber door 6a, 6b are inaccessible (with reference to Fig. 1) prevents to spill from the cold air between refrigerating-chamber door 6a, the 6b in the position along the refrigerating-chamber door 6a in left side.On the other hand, constitute, the thickness direction (drawing dotted line with two point represents) at refrigerating-chamber door 6a when refrigerating-chamber door 6a opens wide does not shake and can counteract the user.

In addition, the refrigerating-chamber door 6b on right side is that the center is joltily supported freely with back shaft S2, and the door storage means 6b1 for the translucent ester moulding of bag shape of the beverage of packing into etc. gives prominence to and is arranged on private side.

Structure as the decompression storeroom 13 of gas regulation chamber is described.

Decompression storeroom 13 shown in Figure 3 is to attract inner airs and decompression to be the gas regulation chamber of subatmospheric air pressure as an example 0.8 air pressure (80kPa) etc. by vavuum pump 12.Promptly, decompression storeroom 13 forms special air ambients such as oxidation to food prevents, the freshness of greengrocery is kept.

As shown in Figure 2, on decompression storeroom 13, be provided with rib 14s in the above as projection.Thus, between decompression storeroom 13 and the dividing plate directly over it 18 be the structure that supports with the state that appropriate gap is set.Be provided with the air entry 19 of the cold air of refrigerating chamber 2 at the rear portion of the storeroom 13 that reduces pressure,, thereby cool off the storeroom 13 that reduces pressure indirectly by attraction decompression storeroom 13 ambient airs and the cold air that flows as shown by arrows.

As shown in Figure 3, in the state of closing cold room door 6b, between the cover 16 of the door storage components 6b1 of refrigerating-chamber door 6b and decompression storeroom 13, form the space of regulation, and constitute mutually and do not contact.

Fig. 4 is the stereogram of decompression storeroom 13 structures seen from oblique front upper place.Decompression storage is 13 to have opening 14r (with reference to Fig. 7) in front, by flat and the long roughly rectangular-shaped outline parts 14 of depth direction and forwardly and the rear move and open and close the cover 16 formation periphery walls of opening 14r.In other words, outline parts 14 are integrally formed with the case shape.

Promptly, for the decompression storeroom 13 in the access reserve, be provided with the cover 16 that opens and closes.Have, the outside of profile parts 14 increases the ribs that section coefficient realizes that intensity improves with linearity or upright being provided with of clathrate outside again.Have, the shape of ribs is not limited thereto again, and realizes that intensity improves as long as increase the section coefficient of outline parts 14.

Externally the shape of profile parts 14 describes.

Use Fig. 5～Fig. 7, externally the shape of profile parts 14 describes.Fig. 5 is the concise and to the point stereogram of the outline parts seen from the front upper place.Fig. 6 is that the C direction of Fig. 5 is to view.Fig. 7 is K-K line cutaway view of Fig. 5.Have, Fig. 5～Fig. 7 eliminates the synoptic diagram that ribs only is imaginary outline parts 14 in order to understand outline parts 14 shapes easily again.

Outline parts 14 use ABS (containing acrylonitrile, butadiene, cinnamic resin), AS (containing acrylonitrile, cinnamic resin) etc. to carry out ester moulding, and form and have the face the wall and meditate shape of 14a, 14b, underside wall 14c, back face wall 14d and upper wall 14e and front openings of both sides.

And, as shown in Figure 3, outside the left side of profile parts 14 face the wall and meditate the rear, outside of 14a be provided with as with the pump connecting portion 14i of the patchhole of the connecting portion of vavuum pump 12.

When reducing pressure in 12 pairs of decompression storerooms 13 of vavuum pump, externally profile parts 14 is pressed by atmosphere outside and the differential pressure of inner low pressure applies load from atmosphere at it comprehensively equably.Because the inside of decompression storeroom 13 is low pressure, so this load the direction of outside-in extruding be applied to outline parts 14 comprehensively on, if its size is 300mm for for example upper wall 14e of outline parts 14, differential pressure is that 0.2 air pressure then is the load of about 180kgf (about 1800N).

For this reason, face the wall and meditate each outside of 14a, 14b, underside wall 14c, back face wall 14d, upper wall 14e, the both sides of outline parts 14 is necessary to increase section coefficient and realizes that intensity improves.For this reason, each face of outline parts 14 is not that plane but the outside are the crooked dome-type roughly curved surface shape in protruding ground.Have, shown in the schematic dotted line of Fig. 5, the outer of outline parts 14 faced the wall and meditated preferably in all crooked laterally shape of depth direction, left and right directions again.

Outline parts 14 are opening 14r width shapes longer than short transverse.In addition, be to have the roughly circular-arc of height from both sides towards center side.Promptly, outline parts 14 are made long roughly rectangular-shaped of flat and depth.Thus, compare face the wall and meditate 14a, 14b, back face wall 14d area of other both sides with upper wall 14e big for underside wall 14c.When reduced pressure in inside, proportional by the load and the area that produce with atmospheric differential pressure, so especially be necessary to guarantee the intensity of underside wall 14c and upper wall 14e.The load of this moment is the load of 14 compressions of external profile parts and the direction of extrusion from the outside, so make the shape of protruding towards the outside of bearing load, the spherical shell that for example makes the part of spheroid improves intensity.

Fig. 6 is that the C of Fig. 5 is to view.As shown in Figure 6, opening 14r is the shape with its face the wall and meditate along both sides on every side 14a, 14b, underside wall 14c, upper wall 14e.Arbitrary wall of outline parts 14 all constitutes the circular shape that protrudes laterally, has again, and Jiang Gebi makes in bight each other the shape that connects by level and smooth circular arc.

When closing aftermentioned cover 16, the seal 16p being located at as crimping on the seal bearing surface 14k of the protuberance of the edge setting of opening 14r on the cover 16 carries out pressurizing window.Promptly, as the seal that the gas between the opening 14r that suppresses cover 16 and outline parts 14 moves, seal 16p is set.

Fig. 7 is the K-K cutaway view of Fig. 5.Promptly, the longitudinal profile of expression outline parts 14, the height dimension of inner face is described.Outline parts 14 are to use the body component behind the ester mouldings such as ABS, AS.The mould that is used to form is roughly divided into the outside mould of the outer shape that forms outline parts 14 and is formed the interior side mold of inner face, resin in mould injection-molded and the cooling after, interior side mold is carried out withdrawing pattern from opening 14r, outline parts 14 are taken out from mould.Mould is this structure, so for interior side mold is carried out withdrawing pattern smoothly to opening 14r side, be necessary to be provided with as upper wall 14e and underside wall 14c from opening 14r side towards back face wall 14d gradually near and the such so-called withdrawing pattern taper that narrows down of back face wall 14d side the samely.So the interior shape of outline 14 is that opening 14r is the broadest, it highly is 14y1.Near the back face wall 14d inner face height is illustrated in figure 7 as 14y2,14y1＞14y2.

In addition, for the width of the outline parts 14 in the section of as shown in figure 20 horizontal direction too, the width dimensions 14x1 of opening 14r and in the back near the width dimensions the wall 14d be 14x1＞14x2.

In order to carry out the withdrawing pattern from mould well, expectation strengthens the angle of withdrawing pattern taper.If but add wide-angle, then the height 14y2 of inner face further narrows down, and storage volume reduces.

Have, as mentioned above, in order to ensure the intensity of outline parts 14, face the wall and meditate 14a, 14b, underside wall 14c, upper wall 14e of expectation both sides is not straight line but makes the spheroid part curve form that protrudes of central authorities like that again.

Secondly, by Fig. 7 to describing towards the preferable shape of the depth direction of the outline parts 14 of back face wall 14d from opening 14r.

During injection molding forming, in order to be angle θ 1 from the minimum of a value that mould takes out required withdrawing pattern taper reliably with outline parts 14.This θ 1 is different because of the material of outline parts 14 and the condition of ester moulding etc., but is 1 ° as an example.Here, if near the imaginary line that underside wall 14c, upper wall 14e are tilted in order to the angle θ 1 of minimum withdrawing pattern taper was connected to back face wall 14d from opening 14r, then the height 14y2 of back face wall 14d was a full-size, internal volume be a maximum.But underside wall 14c, upper wall 14e are straight line, compare dome-shaped curved surface as intended shape near the plane, can't make desired intensity.

So the scope from opening 14r to specific length D1 is the minimum withdrawing pattern taper of angle θ 1.From then on arrive near second taper of inboard back face wall 14d for having the angle bigger than minimum withdrawing pattern taper.Thus, underside wall 14c and upper wall 14e make the structure that has a plurality of gradients respectively.Promptly, underside wall 14c and upper wall 14e and spheroform surface shape approximation, and can strengthen the height 14y2 of back face wall 14d, can satisfy intensity and internal volume simultaneously.

This second taper can be a curved surface, but is similar to by a plurality of imaginary straight lines, thereby simplifies mold shape.Promptly, the scope of D2 is bigger than angle θ 1.Making for example is the withdrawing pattern taper of 2 ° of angles, and the withdrawing pattern taper that the scope of D3 is for example also made 3 ° angle θ 3 greatly than angle θ 2 is with the approximate scope from opening 14r to back face wall 14d of these three imaginary straight lines.Have again, if with D1, D2, and D3 make roughly the same size respectively, then underside wall 14c, upper wall 14e can be made the curved surface with spherical approximation, can satisfy intensity and internal volume simultaneously.

Have, the face the wall and meditate mutual intersection of 14a, 14b and underside wall 14c and upper wall 14e and back face wall 14d of both sides is that crest line all is connected with curved surface again.Have again, by radius is for example made more than the 20mm, thereby can prevent that intersection from stress partly taking place concentrate.

Secondly, use Fig. 8～Figure 10, externally another difformity of profile parts 14 describes.Fig. 8 is the concise and to the point stereogram of other structures of expression outline parts.Fig. 9 is the front view of the outline parts seen from the place ahead.Figure 10 is the K-K line cutaway view of Fig. 8.

With variform structure be from Fig. 5～Fig. 7, underside wall 14c, upper wall 14e from front openings 14r side to the central portion of back face wall 14d, have than upper wall 14e, underside wall 14c to inside protrude above rib 14f, bottom surface rib 14g.In other words, outside the upper wall 14e of profile parts 14 and underside wall 14c go up the mode that prolongs with the 14d that faces the wall and meditates backward from opening 14r be provided with relatively inside side recessed above rib 14f and bottom surface rib 14g.Thus, can increase section coefficient and realize that intensity improves.

As with Fig. 8, Fig. 9, shown in Figure 10, outside in the inboard of the opening 14r of profile parts 14, will from underside wall 14c and upper wall 14e protrude to the inside above rib 14f, bottom surface rib 14g be provided with to back face wall 14d ground from the opening 14r in the place ahead.Have seal bearing surface 14k at the edge of opening 14r, with top rib 14f be inclined-plane 14m, bottom surface rib 14g is that inclined-plane 14n connects respectively.The crest line that inclined- plane 14m, 14n and top rib 14f, bottom surface rib 14g intersect is top top 14h and following top 14j.The part of top rib 14f, bottom surface rib 14g is made the shallow U i section that protrudes to the inside respectively from upper wall 14e, underside wall 14c.Thus, the flexural rigidity of the bottom surface of outline parts 14 and top direction forwards, backwards is also bigger than the shape of Fig. 5～shown in Figure 7.

Relation to cover 16 and opening 14r describes.

Secondly, the relation to cover 16 and opening 14r describes.The aftermentioned that Figure 11 represents cover 16 sealing and is located at cover 16 is strengthened support component H (representing with chain-dotted line) and is inserted into the top rib 14f of outline parts 14, the state between the rib 14g of bottom surface.The interval of top rib 14f and bottom surface strengthening part 14g is that the short transverse of opening 14r is bigger slightly than the height dimension of strengthening support portion H.Thus, strengthening support portion H successfully inserts.

Here, decompression is reduced pressure in the storeroom 13, and the outside of profile parts 14 applies by the load that obtains with atmospheric differential pressure outside, then outline parts 14 are compressed, and above-mentioned gap disappears.So, above-mentioned rib 14f and bottom surface rib 14g respectively with the butt up and down of strengthening support portion H.Thus, owing to can on this, not be compressed, can prevent opening 14r distortion.

On the other hand, in abutting part, outline parts 14 are compressed by atmospheric pressure from the outside, contact with reinforcement support portion H in the time of crooked to the inside.Be not to contact equably promptly,, but strengthen support portion H about hold and contacts with outline parts 14, be in and outline parts 14 between the state of generation reaction force F1.Here, with the width of top rib 14f roughly as L2, with the width of upper wall 14e roughly as L1.So, expect to constitute L1 and L2 about equally.By this structure, the load that is obtained by the differential pressure that is applied to top rib 14f scope and upper wall 14e scope becomes equalization respectively about equally.Thus, be not to concentrate imposed load, but the stress that takes place of rib 14f and upper wall 14e become almost equal in the above at specific part, prevent from can realize long lifeization and high reliability because of the breakage that alternate load etc. causes.

About underside wall 14c and bottom surface rib 14g, the identical size shape of relation with top rib 14f and upper wall 14e is made in expectation.

Secondly, by Figure 24 to describing by other effect that top rib 14f and bottom surface rib 14g obtain is set.Near the partial sectional view of the section the seal 16p when Figure 24 is 16 sealings of expression cover.

In Figure 24, the edge part of the opening 14r of outline parts 14 and seal 16p seal bearing surface 14k butt.The outer peripheral face 16p2 of seal is positioned at the outside (diagram upside) of opening 14r than seal bearing surface 14k, and on the other hand, the inner peripheral surface 16p1 of seal is positioned at the inboard (diagram downside) of opening 14r than seal bearing surface 14k.Strengthening support portion H is configured in than the inner peripheral surface 16p1 of seal and also leaves on the position apart from ph of inboard (diagram downside) of opening 14r.By this configuration, thereby even, also can finish butt each other reliably owing to the site error of seal 16p and seal bearing surface 14k is offset.In addition, even the load that reinforcement support portion H and upper wall 14f are obtained by differential pressure is crimped and reaction force F1 takes place, can the sealing that be obtained by seal 16p not impacted yet.In addition, owing to be said structure,, top rib 14f leaves inboard (diagram downside) apart from pf so being configured in apart from the seal bearing surface 14k that is positioned at the edge of opening 14r.Here, will from seal bearing surface 14k to above rib 14f as inclined-plane 14m, then owing to strengthen support portion H and successfully insert, so more convenient.

Outside the bottom surface side of profile parts 13 too, bottom surface rib 14g is configured in seal bearing surface 14k apart from the edge that is positioned at opening 14r apart from the inboard of ph.

As mentioned above, top rib 14f is protruded to the inside from upper wall 14e, bottom surface rib 14g is protruded to the inside from underside wall 14c.Thus, improve the intensity of outline parts 14, improve reliability.Have again, also reliable by the sealing that seal 16p obtains, with strengthening the distortion that support portion H effect can be supported the reaction force that is caused by differential pressure and prevent the opening 14r of outline parts 14.

Secondly, according to Figure 10 the shape of the depth direction from opening 14r to back face wall 14d is described.It is the withdrawing pattern taper of θ 4 towards back face wall 14d angle that top rib 14f and bottom surface rib 14g part also need from opening 14r, and θ 4 〉=θ 1.Here, be that the taper of greatest hope withdrawing pattern is as far as possible little for internal volume.Thus, expectation θ 4=θ 1.Top rib 14f and bottom surface rib 14g have the roughly section of U font as shown in figure 11, so become the strengthening part of flexural rigidity.Meanwhile, be and strengthen the structure that support portion H butt suppresses the opening 14r bending that caused by differential pressure.Thus, as shown in figure 10, even also can guarantee intensity towards the rectilinear form of the direction withdrawing pattern taper θ 1 of back face wall 14d from opening 14r.Here, with top rib 14 and bottom surface rib 14g in the back near the height the wall 14d as 14y2, if underside wall 14c and upper wall 14e near the height of wall 14d in the back equate, the shape of then top rib 14f and bottom surface rib 14g and underside wall 14c and upper wall 14e is guaranteed after minimum the withdrawing pattern taper or the withdrawing pattern taper on this, can further satisfy intensity and internal volume simultaneously, thereby be good.

As mentioned above, the shape of not only above-mentioned outline parts 14 also both sides face the wall and meditate 14a, 14b, underside wall 14c, back face wall 14d, upper wall 14e, above increase the rib that section coefficient realizes that intensity improves with upright establishing such as linearity, clathrate on each outside of rib 14f, bottom surface rib 14g, guarantee to resist the further intensity of the distortion that causes by differential pressure.

Outline parts 14 are made above-mentioned shape, and integrally formed by resin, thereby simplify and lightweight decompression storeroom 13 time, also can realize constituting at an easy rate.

Relation to dividing plate 18 and decompression storeroom 13 describes.

According to Figure 25, the 26S Proteasome Structure and Function of rib 14s is described.Figure 25 is the partial sectional view of the D-D section in Figure 12 of expression decompression storeroom 13 and dividing plate 18.

Outside on the profile parts 14 on top the upright rib 14s that is provided with.Thus, be with at decompression storeroom 13 with between its square dividing plate 18, be provided with the structure that the state of specified gap supports.Promptly, be positioned at decompression storeroom 13 directly over dividing plate 18 on when having placed food, dividing plate 18 bendings, but when bending above the rib 14s below dividing plate 18 butt.Decompression storeroom 13 constitutes, greatly and not can be crooked by outline parts 14 and the reinforcement support portion H rigidity of being located at cover 16, even so on dividing plate 18, placed the occasion of weight thing, also can suppress the bending of dividing plate 18, the rigidity of dividing plate 18 is little also passable, does not need special to strengthen waiting and suitable.

In addition, as shown in Figure 12 and Figure 13, on the central portion 16c2 of cover 16, be provided with and differential pressure extracted out valve V and be inserted into differential pressure extraction hole 16a in the decompression storeroom 13.

And, on cover 16, as shown in figure 13, be provided with rotationally freely around back shaft 35s differential pressure extracted out valve V opens and closes and the valve of the spool 35t that is made of the rubber with elastic property and flexibility etc. opens and closes parts 35.

Here, the back shaft 16s (with reference to Fig. 4, Figure 17) that back shaft 35s that valve switching parts 35 rotate and switching handle 26 rotate constitutes with one heart, and constitutes the opening and closing operations that makes switching handle 26 opens and closes parts 35 and spool 35t by valve on-off action interlock.

The structure that opens and closes handle 26 is described.

Shown in Fig. 4, Figure 13, Figure 16, Figure 17 etc., open and close handle 26 and possess: with the barred body 27 of aluminium bar formation; One square end portion is fixed on the metal support portion 28,29 on the two ends, the left and right sides of this barred body 27 respectively; And insert barred body 27 and be used for the handle operation portion 36 of handle operation at central portion.

Open and close handle 26 about support portion 28,29 back shaft 16s, the 16s of central portion separately around about cover 16 supported rotationally automatically, support guide roller 28r, 29r rotationally freely on the opposing party end.

As shown in figure 13, it is supported rotationally freely around back shaft 16s, the 16s of the left and right sides of cover 16 sidepiece to open and close handle 26, make barred body 27 be positioned at around about the occasion of foot of rotary motion trace of back shaft 16s, 16s, be by opening and closing the state after handle 26 inaccessible covers 16 lock, on the other hand, as shown in figure 16, make barred body 27 be positioned at around about the occasion of top of rotary motion trace of back shaft 16s, 16s, become the state of release by the locking of the cover 16 that opens and closes handle 26 and carry out.

Open and close handle 26 about guide roller 28r, the 29r of support portion 28,29 cover lock that is embedded into the side walls 14a, the 14b that are located at decompression storeroom 13 both sides respectively accordingly decide in the guide groove component 30,30, carry out the locking of the cover 16 that undertaken by switching handle 26.

Figure 21, Figure 22, Figure 23 are the cover 16 of expression decompression storeroom 13 shown in Figure 16 and the support portion 28 that opens and closes handle 26 and the enlarged drawing that carries out locking process around the switching handle 26 that cover lock is decided guide groove component 30.

Have, Figure 21 is expression by the figure of the locking release conditions that open and close the cover 16 that handle 26 carries out again, and Figure 23 is expression by the figure of the lock-out state that opens and closes the cover 16 that handle 26 carries out, Figure 22 be expression Figure 23 will lock-out state figure.

Have, the cover lock in left side is decided guide groove component 30 owing to be to decide the identical structure of guide groove component 39 with the cover lock on right side, describes so the cover lock on right side is decided guide groove component 30 again, and the cover lock that omits relevant left side is decided the explanation of guide groove component 30.

As Figure 21, Figure 22, shown in Figure 23, cover lock is decided the parts that guide groove component 30 for example is an ester moulding, is that the madial wall guide 30a of guide roller 28r and the curved shape of side-looking guides contiguously.

The madial wall guide 30a side-looking that cover lock is decided guide groove component 30 forms following shape.

Promptly, as shown in figure 21, will connect by size between intersection point 30a1 straight line and madial wall guide 30a in the axle center of back shaft 16s in the locking release conditions that open and close the cover 16 that handle 26 carries out and guide roller 28r and the back shaft 16s as c.In addition, as shown in figure 22, will connect by size between intersection point 30a2 straight line and madial wall guide 30a in the axle center of back shaft 16s that will lock that opens and closes the cover 16 that handle 26 carries out and guide roller 28r and the back shaft 16s as b.In addition, as shown in figure 23, will connect by size between intersection point 30a3 straight line and madial wall guide 30a in the axle center of back shaft 16s in the lock-out state that opens and closes the cover 16 that handle 26 carries out and guide roller 28r and the back shaft 16s as a.

The curve of setting up with the relation of b (will lock-out state (Figure 22))＞a (lock-out state (Figure 23))＞c (locking release conditions (Figure 21)) between this a, b, the c connects, and forms the shape with side-looking such as Figure 21, Figure 22, madial wall guide 30a shown in Figure 23.

Decide the madial wall guide 30a shape of guide groove component 30 by this cover lock, cover 16 that switching handle shown in Figure 22 26 carries out will lock-out state in, connect between intersection point 30a2 straight line and madial wall guide 30a in axle center of back shaft 16s and guide roller 28r and the back shaft 16s and be of a size of the b maximum.Thus, as shown in figure 22, the madial wall guide 30a that the guide roller 28r of support portion 28 and cover lock are decided guide groove component 30 butt or generation strongly turns round sled.Thus, the user that the switching handle 26 that supports with support portion 28 is carried out opening and closing operations gives cover 16 blocked senses of touch.Promptly, form madial wall guide 30a in the mode that gives to lock again after the pause and transition in rhythm or melody sense.

Promptly, the user controls the handle operation portion 36 that opens and closes handle 26, the handle operation portion 36 that opens and closes handle 26 of will lock-out state pushing downwards from Figure 22, occasion to lock-out state arrival shown in Figure 23, according to the relation of b (will lock-out state (Figure 22))＞a (lock-out state (Figure 23)), the guide roller 28r of the support portion 28 of neutral condition turn round sled promptly, stronger butt degree relaxed.Thus, user's switching handle 26 in the transfer operation of locking, constitute, open and close the sense of touch of handle 26 from will lock-out state entering lock-out state.

And, when opening cover 16, the user control open and close handle 26 control operating portion 36 via Figure 22 will lock-out state, the barred body 27 that opens and closes handle 26 is upwards lifted, arrive to locking release conditions shown in Figure 21.This occasion connects between intersection point straight line and madial wall guide 30a of back shaft 16s and guide roller 28r and the back shaft 16s and is of a size of c, and comparing will lock-out state (with reference to Figure 22), lock-out state (with reference to Figure 23) minimum.Thus, form madial wall guide 30a as follows: though the i.e. temporary transient part by the heavier sense of touch that will lock, the guide roller 28r of support portion 28 can not contact the operation that just can open and close handle 26 with the sense of touch of mitigation with the madial wall guide 39a that cover lock decide guide groove component 30 during from the state of Figure 22 to the opening-wide state of Figure 21.

The function of the grip part when the handle operation portion 36 (with reference to Figure 13, Figure 16) in the handle 26 of opening and closing has user's controlled opening/closing handle 26 and differential pressure is extracted out the function of the switching channeling conduct of valve.Promptly, make the opening and closing operations of being undertaken open and close the open and close valve action interlock of parts 35 and spool 35t by valve by the rotation that opens and closes handle 26.As shown in figure 13, when closing when opening and closing handle 26, then spool 35t closes valve, as shown in figure 16 when rotary opening closing handle 26 releases upwards then spool 35t drive valve.

Open the state behind the valve, shown in the arrow of Figure 16, invade in the decompression storeroom 13 after being depressurized by the pressure differential atmosphere outside and to eliminate differential pressures, be applied to the load that the differential pressure on the cover 16 when opening cover 16 causes and disappear, can successfully open cover 16.

After this cover 16 is closed, to push after for example not shown console switch or closing cold room door 6b connect not shown door switch etc. the user, the running of vavuum pump 12 begins, and attracts the air in the decompression storeroom 13 to begin decompression.

When beginning to reduce pressure, then cover 16 pushes from the outside by the differential pressure of atmospheric pressure and inner low pressure, and seal 16p pushes with the external profile parts 14 of the pushing more than the power that is locked by handle.The recess 16p1 of seal 16p fits tightly becomes state shown in Figure 13, the bigger load seal 16p that obtains owing to the differential pressure by atmospheric pressure and inner low pressure is squeezed the bigger surface pressing of generation, so sealing further becomes well, can keep inner negative pressure.

According to above structure, reduce pressure by driving vavuum pump 12, be negative pressure thereby make the inside of decompression storeroom 13, and can keep negative pressure.Here, the usefulness plastics are integrally formed forms for the outline parts 14 by the storeroom 13 that will reduce pressure, and then can constitute at an easy rate.In addition since except the opening 14r of front for sealed integratedly, so by with seal 16p only to sealing between cover 16 and the opening 14r, thereby can guarantee the sealing of integral body well.

Secondly, be configured in the transparent ester moulding products that food discs 17 in the above-mentioned outline parts 14 are AS etc.To shown in Figure 20, have two side 17a, 17b, underside wall 17c, back face wall 17d and front side wall 17e as Figure 13.

On the front side wall 17e of food disc 17, be formed for disposing the recess 17f of reinforcement described later support portion H.In addition, as shown in figure 19, on the bottom, two sides of the front side wall 17e that forms recess 17f, be formed for food disc 17 is installed on the cover 16 and with a pair of mounting jaw 17t, the 17t of the on-off action interlock of cover 16, form a pair of projection 17g, 17g near the back face wall 17d below underside wall 17c.

This mounting jaw 17t, 17t form the semicircle tubular of lower openings, and the underside wall 13c that projection 17g, the 17g of food disc 17 is placed on outline parts 14 goes up and cooperates (with reference to Figure 19) with jut 16g, the 16g of the inboard of cover 16.Thus, food disc 17 is installed on the cover 16 and with the on-off action interlock of cover 16.

Thus, the user can visually be accompanied by in the food disc 17 that the on-off action of cover 16 extracts out, can easily take out the food in the food disc 17.

Secondly, use Figure 20, Figure 13, Figure 15 that the support of food disc 17 is described.Food disc 17 is installed on the cover 16, is formed for a pair of mounting jaw 17t, 17t with the on-off action interlock of cover 16.Near the back face wall 17d below underside wall 17c and two side 17a, 17b near a pair of projection 17g of formation, 17g.And, as shown in figure 15, under underside wall 14c that is placed on outline parts 14 and cover 16 closing state, form specified gap gap as shown in figure 13 below underside wall 17c and between the rib 14g of bottom surface.

Here, the inside of reducing pressure storerooms 13 when starting vavuum pump 12 becomes negative pressure, and then outline parts 14 deform because of atmospheric pressure is attracted to the inside.Especially the upper wall 14e that area is big, underside wall 14c are crooked to the inside with top rib 14f, bottom surface rib 14g.This amount of bow substantial middle of rib 14f, bottom surface rib 14g in the above partly is maximum, but because store food in the food disc 17, so when the bending of outline parts 14 greatly time the, then upper wall 14e and Food Contact, perhaps food disc 17 rises, and food is arranged again from being compressed up and down.

Promptly, below the underside wall 17c of and food disc 17 crooked during butt at bottom surface rib 14g, then the central portion of food disc 17 can rise.Thus, food disc 17 whole rises are and unstable, and all rise significantly in which bight of rocking food disc 17.

Here, cover 16 sides as the front side of food disc 17 are installed on the cover 16 by a pair of mounting jaw 17t, 17t.Thus, even outline parts 14 are crooked to the inside because of differential pressure, cover 16 can be not crooked yet, so the position of mounting jaw 17t, 17t can not change.In addition, be located at two side 17a, 17b neighbouring a pair of projection 17g, the 17g of the inboard of food disc 17 are placed on the underside wall 14c of outline parts 14.Promptly, projection 17g, 17g are arranged on the rear, bottom surface of food disc 17 as leg section.Thus, the opening 14r of profile parts 14 occasion of closing with cover 16 has the gap between the underside wall 14c of profile parts 14 and the food disc 17 outside outside.In addition, projection 17g, 17g are located near the sidewall, so even the underside wall 14c of outline parts 14 is because of the crooked upward occasion of differential pressure, amount of bow is in the middle body maximum, crooked hardly near the two side, so a pair of projection 17g, the 17g of food disc 17 also move hardly in this position, so food disc 17 can not rise.

Here, the gap gap that is located between the following and bottom surface rib 14g of underside wall 17c of food disc 17 is set at bigger than the amount of bow of the bottom surface rib 14g that is caused by negative pressure.Thus, though bottom surface rib 14g bending, also not can with the following butt of the underside wall 17c of food disc 17, so food disc 17 integral body can not rise and be good.

In addition, as the material of outline parts 14, in the intensity of the load that the differential pressure when reducing pressure in inside for obtaining bearing causes also the amount of bow when lowering decompression make and leave inner food in and can not compress the high material of expectation rigidity.As an example,, enumerate and sneak into glass fibre and carbon fiber carries out reinforced ABS material etc. as fibrous reinforcement packing material.Thus, bending is emphasized to become big and Young's modulus (coefficient of elasticity) also becomes greatly, can be fit to use as outline parts 14.

So, integrally formed by outline parts 14 are done resin, thus decompression storeroom 13 can be oversimplified lightweight, and can constitute at an easy rate.
