Abstract

An ice reservoir container for a refrigerator comprises a reservoir chamber (6) which has a base (27) which slopes along a first vertical section plane towards an outlet opening (28). The gradient of the base (27) decreases along the section plane as the distance from the outlet opening (28) increases.

Description

Refrigerator and the ice storage container that is used for refrigerator

Technical field

The present invention relates to refrigerator, especially have the domestic refrigerator or the combination of refrigerator freezing equipment of ice dispenser, and the ice storage container that is used for this ice dispenser.

Background technology

The ice dispenser that is used for refrigerator is known from US 5 273 219, it is divided into storage box and disintegrating machine, have lifting and hopper between storage box of being arranged in and the disintegrating machine, described tube transfers out storage box by its rotation in a controlled manner with ice cube and enters disintegrating machine.Storage box has towards promoting and the downward-sloping base plate of hopper, so that ice cube tends to be collected in the place, end of contiguous lifting of storage box and hopper.When the quantity of storage box medium floe is very little, this tendency be expectation to guarantee that ice cube can be caught and be transported away by cylinder always.If yet the fill level of storage box is very high, the inclination of base plate increases ice cube with respect to promoting and the pressure of hopper, this cause promoting and hopper near ice cube have wedging relative to each other and freezing increase is inclined to.Although ice cube can be loose by the agitator fragmentation that is installed in the storage box once more, this causes ice cube in the storage box frangible and may be chilled in and become erose bulk together after long-time.

Summary of the invention

Target of the present invention is to create a kind of storage container, and its medium floe can intactly be stored for a long time and can be transported away without difficulty at any time.

This target realizes that by a kind of ice storage container with storage chamber the characteristics in storage chamber are the base plates that slopes down to outlet along the first vertical cross sectional plane, and base plate increases along with the distance apart from outlet and reduces along the gradient of transversal plane.Thereby the weight away from the ice cube that exports in the ice storage container does not have influence or influences very little the suffered pressure of ice cube under the high fill level in exit.This reduced ice cube freezing together tendency and correspondingly when need be with ice cube broken they to become the possibility of fragment also very little.

Gradient can reduce continuously along first transversal plane; Yet also can consider the cross-sectional form that gradient reduces by stages.

In order to make that ice cube can be broken when needed, agitator is set in storage container.This agitator preferably can be around the axis rotation of extending in transversal plane.

The preferred characteristics of agitator are the pushers that stretch out from radial axis ground, and pusher increases along with the distance apart from outlet and reduces in the radial direction length, therefore keeps gap width about equally between the base plate of longitudinal end that can realize pusher on the whole length of agitator and storage container.

Agitator can be the bar of its shape bending in a plane.

This target realizes by a kind of refrigerator that also it has ices storage container as defined above.

The specific embodiment

Have adiabatic framework 1 and door 2 with the refrigerator shown in the schematic cross-section among Fig. 1, they limit inner 3.Inner 3 remain below 0 ℃ temperature by evaporimeter, and evaporimeter is contained in the upper area of framework 1 in the separated evaporator chamber.Automatic ice-making device 5 is arranged as the evaporator chamber 4 among the next-door neighbour inner 3, so that it preferably can make the cold air from evaporator chamber 4 be applied to ice maker.In the known way that is not shown specifically in the drawings, ice maker comprises a plurality of moulds, is used for automatically water being metered to the device of mould and also is useful on the device of automatically ice cube of finishing being discharged from mould.Be the open-topped storage chamber 6 towards ice distribution module 7 below ice maker 5, storage chamber 6 receives the ice cube of discharging.Most of degree of depth of ice distribution module 7 extend through inside 3 and for example can be injection-molded en bloc or by a plurality of injection mould plastics assemblings by plastics.Be contained in ice distribution module 7 rear recess 8 in be the motor that is used to drive agitator 9.Motor can for good and all be installed on maybe can be integrated in the refrigerator ice distribution module in and can be removed together with the latter.Agitator 9 on inner 3 the vertical direction or storage chamber 6 vertically on extend through the latter and by the crusher chamber 10 adjacent with the storage chamber 6 of adjacent doors 2.

Agitator 9 is metallic rod, and it is crooked in the plane parallel with its rotating shaft with sawtooth form in the part that extends through the storage chamber.Penetrating attached in the part of crusher chamber 10 at agitator 9 is the knife of fragmentation cell, so that they rotate along with the rotation of agitator 9.Be contained in other knife 12 in the crusher chamber 10 can be therein they rotate together with knife 11 and equally with them when penetrating crusher chamber, only be broken (for example under the help at excellent (not shown) between they and the knife 11 as the state of the pusher of ice cube and its medium floe, rod can be urged wall by crusher chamber 10, maybe can make knife 12 rotations to hinder when needed) stationary state between change.

By the opening on the downside of crusher chamber 10, ice (be broken or become piece according to the state of knife 12) arrival passage 13, passage 13 extend through the insulation material layer of door 2 and outwards open and enter in the depression 14 of the outer openings of door 2.Baffle plate 15 keeps passage 13 closures to infiltrate inner 3 to prevent warm air usually.Baffle plate 15 is only opened when ice being dispensed into the container that is positioned in the depression 14 by passage 13 in agitator 9 rotation.

Water pot 16 is embedded in the insulating materials of door 2 on the rear wall of depression 14.Water pot 16 is being connected to the drinking water network as ice maker 5 via supply line 17 and stop valve 18 on the side and is being connected to dispensing nozzle 19 in the depression 14 on opposite side.

Fig. 2 illustrates the perspective view of the shell 20 of ice dispenser module 7, and it limits storage chamber 6 together with the relative part (not shown) with the mode substantial symmetry of mirror image.On the rear side of shell 20, can see the depression that is used to be contained in not shown motor.The otch part relative with it that faces depression 8 on the rear wall 25 of shell 20 forms ox-eye 21 together, and ox-eye 21 will hold columniform basically connector 22 so that it can rotate.Connector 22 faces in Fig. 2 on observer's the front side has slit 23, and the corner ends of agitator 9 (not shown in Fig. 2) can be inserted in the slit.Unshowned otch makes the interlocking that can realize motor engage on the rear side of connector 22.

Storage chamber 6 has base portion 27, it tilts to the antetheca 26 of contiguous crusher chamber 10 in the vertical from rear wall 25, this causes that the ice cube that is carried by agitator moves towards crusher chamber 10 and finally arrive crusher chamber 10 (not shown in Fig. 2) by the opening in the antetheca 26 28 when agitator 9 rotations.The gradient of base portion 27 26 increases so that the tendency that ice cube moves towards crusher chamber 10 is then big more the closer to described chamber always continuously from rear wall 25 to antetheca.Orientate as near the ice cube of rear wall 25 thereby seldom influence near the ice cube that is positioned at the antetheca 26 and on the direction of crusher chamber 10, be applied to the pressure of these ice cubes.This means that the tendency that these ice cubes are chilled in together or stop up is very little, even the ice in storage chamber 6 has high fill level.

Fig. 3 illustrates the cross section of running through ice dispenser module 7 with the rotation of agitator with meeting at right angles.Base portion 27 has the semi-circular cross-section shape, and the rotation of agitator 9 extends through the central point of the circle of base portion 27.This means in storage chamber 6 do not have the bight, ice cube can be wedged described bight and can hinder the rotation of agitator 9.

In order to prevent effectively that the ice cube of storing in the chamber 6 is chilled in together, expectation is rotating spoon 9 usually, even is not having ice will divide timing.Considered that multiple scheme avoids the not desired output of icing during the rotation of agitator 9.Scheme is based on the fact of having mentioned: the knife 12 in the crusher chamber can be with knife 11 rotations.Thereby closeable baffle plate is provided and is enough with knife 12 with agitator 9 rotations in output place of crusher chamber 10, baffle plate is closure when not wishing ice output is arranged.In this case, ice cube will move in storage chamber 6 and in crusher chamber 10, rather than be broken.

But alternative plan is to provide closed baffle plate between storage chamber 6 and crusher chamber 10.When it was closed, agitator 9 and knife 11 can rotations under the state that does not rely on knife 12 (fixing or rotatable).

Third party's case is to provide colligator between knife 11 and agitator 9, and this allows 9 rotation while of agitator knife 11 to keep static, and thereby prevention ice enters crusher chamber 10 or ice is exported from described chamber.

Fig. 4 illustrates the longitudinal cross-section of running through second embodiment that stores chamber 6.This curved shape in the longitudinal cross-section of base portion 27 in the figure shown in Fig. 2 is depicted as has the gradient that increases continuously towards antetheca 26, in the embodiment shown in Fig. 4, storage container is divided into a plurality of

sections

29,30,31 in the vertical, and the gradient of base portion 27 is constant in each section in each case, and 26 increases by stages from rear wall 25 to antetheca at the boundary of

section

29,30,31.The design of agitator 9 is fit to the shape of base portion 27; Be formed at amplitude 26 increases of each the wavy thing 32 in the agitator 9, cross base portion 27 so that move with the distance that equates basically at the peak of all wavy things 32 towards the front side.

Cross section shown in Fig. 4 also illustrates the end part of the agitator of mentioning with reference to Fig. 1, use digital 24 marks in this drawing, the slit 23 that it inserts connector 22 also illustrates two otch 33 on the rear side of connector, and this allows the forward of motor and negative sense to engage.
