According to the present invention's preferred embodiment, when handle 32 is in the second place (the first auxiliary section 34 and the second auxiliary section 44 are in locked position), the front surface of handle 32 is approximately perpendicular to horizontal plane and is in vertical position, and this is particularly conducive to and is retracted in the first resettlement section 30a by handle 32.Preferably, at least overwhelming majority being in the handle 32 of the second place is accommodated in receiving space 30, takies volume with what reduce low pressure storage unit 7.Particularly preferably, the handle 32 being in the second place is contained in a body 26 completely, does not exceed the front surface of door 10.

Door 10 is provided with to limit handle 32 in rotation to the second position limiting structure 47 continuing time perpendicular (second place) to rotate, this can prevent handle 32 from continuing rotate and cause the upper end of handle 32 to protrude from outside receiving space 30, makes the outward appearance of door 10 seem more comparatively smooth.

Second position limiting structure 47 is arranged between handle 32 and door body 26.It can by be fixed on inside handle 32 and/or bulge-structure then on front side of door body 26 is formed, and so arrange: when the front surface of handle 32 is in vertical position, the second position limiting structure 47 be fixed on a body 26 is just connected to the inner side being positioned at the part below the body of rod 33 of handle 32, or the second position limiting structure be fixed on inside handle 32 is just connected to the front side of a body 26.

When handle 32 is in the second place, these bulge-structures preferably near the madial wall of the first resettlement section 30a, to reduce the possibility that it conflicts with the hand of user.Second position limiting structure 47 can be formed on a body 26 and/or handle 32 one-body moldedly.

When door 10 will be opened, the lower end that user can hold handle 32 is upwards outwards lifted, handle 32 rotates around the central shaft X of the body of rod 33, and drive the body of rod 33 to carry out axle rotation, the first auxiliary section 34 being fixed on the body of rod 33 two ends is rotated down, and sticking department 46 leaves the cam curved surface 34a of the first auxiliary section 34 gradually.In this process, charge valve 25 also relieves closing filling channel 19, and extraneous gas enters storeroom 15 by filling channel 19 and balances external and internal pressure.Afterwards, user can hold handle 32 and draw forward, can open door 10.

Door 10 can be provided with to limit the first position limiting structure 48 that handle 32 continues after to inner rotary to primary importance to rotate.In primary importance, the angle between handle 32 and fore-and-aft plane is less than 90 degree, and in a preferred embodiment, handle 32 to when becoming 30 degree-60 with perpendicular and spend (such as 50 degree), is namely limited continuation to inner rotary by rotation.

First position limiting structure 48 can so be arranged: after handle 32 arrives primary importance to inner rotary to maximum angle, and the first position limiting structure 48 is connected to the inner side being positioned at the part above the body of rod 33 of handle 32.Preferably, first position limiting structure 48 arranges near the upper inside walls of the first resettlement section 30a and maintains a certain distance with the latter, when handle 32 rotates to primary importance, the inner side that handle 32 is positioned at the part on the body of rod 33 abuts with the first position limiting structure 48, and further rotating of handle 32 is limited.

First position limiting structure 48 can be formed by the bulge-structure being positioned at the first resettlement section 30a.This bulge-structure can one-body moldedly on the rear side inwall of the first resettlement section 30a.

In the present invention's preferred embodiment, the appliance door of refrigerating appliance 1 be in closed condition and the door 10 of low pressure storage unit 7 is in the closed position but handle 32 is in the second place (extended position) time, the inner side of appliance door and handle 32 maintain a certain distance in order to avoid cause damage to low pressure storage unit 7 when closing appliance door.Therefore, by the angle of handle 32 to inner rotary is limited within the specific limits, the length that handle 32 is given prominence to forward can be limited within the specific limits, thus, distance between inside the appliance door of low pressure storage unit 7 and refrigerating appliance 1 can be reduced, and then can increase the space availability ratio of refrigerating appliance 1.

As shown in Fig. 6,11b, when handle 32 is in the second place, the front end being in the first auxiliary section 34 of the second extreme position is formed overlapping with the sticking department 46 of the second auxiliary section 44 in the longitudinal direction.In order to avoid when the door 1 being in pull-out state is pushed closed position by user the first auxiliary section 34 front end impact sticking department 46 and cause the damage of low pressure storage unit 7, according to the present invention's preferred embodiment, as shown in Fig. 9, Figure 12 a and 12b, door 10 comprises in order to the first auxiliary section 34 is remained on the maintaining body 49 of a home at door 10 after locking state is removed, this home is so selected: in the process that door 10 is closed, and the first auxiliary section 34 of advance the puck is in can not the home of striking lock bonding part 46.

In a preferred embodiment, maintaining body 49 realizes the first auxiliary section 34 to remain on described home by handle 32 being remained on a security standpoint.This security standpoint can equal the angle (the maximum outside anglec of rotation) when handle 32 is in primary importance and between fore-and-aft plane or be slightly less than this maximum outside anglec of rotation, that is, the home of the first auxiliary section 34 can be its first extreme position or close first extreme position.Be appreciated that, when handle 32 is in primary importance/extended position, the front end of the first auxiliary section 34 and sticking department 46 in the longitudinal direction should not be overlapping.

In an embodiment especially easily realized, maintaining body 49 comprises spring.Preferably, maintaining body 49 can be fixed on a body 26 by first end 49a or be immovably fixed on parts (such as fixture 28) on a body 26, torsion spring that the second end 49b is fixed on handle 32 realizes.After handle 32 is in primary importance, torsion spring can apply an outside twisting resistance makes handle 32 have the power continued to inner rotary to handle 32, on the other hand because the restriction of handle 32 by the first position limiting structure 48 cannot continue to rotate, therefore it is securely held in primary importance.

In an embodiment of the invention, maintaining body 49 is also configured to inside twisting resistance to be provided can not to stick up to make the lower end of handle 32 to the handle 32 being in the second place, and then handle 32 is reliably remained on vertical position.

Therefore, for the holding device 49 that can provide rightabout twisting resistance respectively to the handle 32 being in primary importance and the second place, when handle 32 is in an equilbrium position between primary importance and the second place, handle 32 can be in balance.When handle 32 from this equilbrium position slightly toward inner rotary, then it can be made to inner rotary for the twisting resistance that holding device 49 provides to handle 32 until handle 32 arrives primary importance and is limited to continue to rotate; When handle 32 from balance angle slightly toward interior rotation after, inwardly rotate under the effect of the inside twisting resistance that handle 32 can apply at holding device 49 until handle 32 arrives the second place and is limited to continue to rotate.

Although in the embodiment above, by same torsion spring, handle 32 is remained on primary importance and the second place respectively, the present invention should not be confined to this.Such as, in other examples, the holding device in order to handle 32 to be remained on respectively primary importance and the second place also can be provided separately.

Owing to there is gap between container 12 and main body 8, even if container 12 or door 10 are supported in main body 8 by telescopic guideway unit 14, being pulled out in main body 8 or push the process of main body 8 by the drawer unit comprising door 10, drawer unit can rock in scope at one and rock.This rocks scope and be correlated with in the gap between drawer unit and main body 8, and is subject to the impact of the intensity of telescopic guideway unit 14 (if any).Thus, when door 10 is in closed condition, possibly cannot aim at exactly between door 10 and main body 8, and potted component 16 cannot be positioned on interface 18 well, the first auxiliary section 34 and the second auxiliary section 44 also likely cannot be in suitable pre-engaged location.In order to improve this point, according to the present invention's preferred embodiment, low pressure storage unit 7 comprises detent mechanism, it is less than above-mentioned rocking in the fixed range of scope in order to door 10 be positioned when door 10 is closed a fixed position or be positioned one, thus is located accurately between door 10 and main body 8 when making door 10 in the closed position.

Detent mechanism comprises the first location division 51 of being positioned on door 10 and is positioned at the second location division 52 coordinated in main body 8, with the first location division 51.As shown in Figure 8, the first location division 51 is not arranged in a body 26 with not exceeding end face 26b, 26c, 26d, 26e of a body 26.In the present embodiment, the first location division 51 be positioned at potted component 16 outside, with wear groove 42 and be disposed adjacent.As Fig. 3,4, shown in 5a, 5b, the second location division 52 is positioned at the front of interface 18, and to extend from interface 18 to front protrusion, but not arrange with not exceeding the outer knuckle of front connection box 17.

Therefore, when door 10 close, the first location division 51 and the second location division 52 coordinate time, the second location division 52 is housed in door 10, and in annular region between potted component 16 and the surrounding end surfaces 26b ~ 26e of door 10.First location division 51 and the second location division 52 are arranged in the mode of the outer surface not being exposed to low pressure storage unit 7 when door 10 is closed, not only be beneficial to attractive in appearance, and when low pressure storage unit 7 be arranged on fresh-keeping between in room 4 time the distance that additionally need not increase between low pressure storage unit 7 and inner bag 2b for detent mechanism.

First location division 51 and the second location division 52 preferably with form fit the mode that is connected arrange.In the present embodiment, the first location division 51 is made up of the slot be positioned on door 10.Slot in the side opening of agent-oriention 8 to allow the insertion of the second location division 52.When door 10 is in the closed position, the second location division 52 is inserted in the first location division 51, and the outer surface of the second location division 52 is close to the respective inner surfaces of the first location division 51 and the transverse shifting of limiting door 10 and vertically moves, thus door 10 is accurately positioned.

Protrude from forward interface 18 due to the second location division 52 and insert in the first location division 51 when door 10 not yet arrives closed position, therefore detent mechanism 50 also the motion of opposite house 10 can play guiding function, and this can reduce door 10 and pellet type container 12 rocking in closing process to a certain extent.The slot of the first location division 51 can be set to have the wedge-shaped slot that opening portion is maximum, shrink gradually from back to front, correspondingly the insertion section of the second location division 52 also have shrink gradually from back to front, the shape of the minimum wedge shape in leading section.Therefore, when just inserting, the second location division 52 can extremely be easily inserted in the first location division 52, along with door 10 is gradually near closed position, gap between first location division 51 inner surface and the second location division 52 outer peripheral face on horizontal and vertical reduces gradually, and makes can shaking degree reducing gradually of the drawer unit comprising door 10.When door 10 arrives closed position, therebetween gap reaches minimum (such as 1-2 millimeter), thus door 10 is positioned in one is significantly less than in the fixed range that maximum in closing process of drawer unit rocks scope (occur in the first and second location divisions 51,52 coordinate before).Certainly, In an alternative embodiment, when door 10 arrives closed position, the first location division 51 and the second location division 52 can fit tightly, thus door 10 is positioned on a fixed position when closing.

Particularly preferably, the second location division 52 is directly formed by the base portion 45 of the second auxiliary section 44.Should be appreciated that in other examples, the second location division 52 is made up of the insertion section independent of the second auxiliary section 44 and is also fine.

In addition, in other examples, the second location division 52 is made up of slot, the first location division 51 is made up of the insertion section in insertion second location division 52 is also possible.
