Description

Refrigerating device

Technical field

The utility model is related to refrigerator storing technical field, more particularly to a kind of refrigerating device.

Background technology

Refrigerator is to maintain a kind of refrigeration plant of constant low temperature, is also that one kind makes food or other articles keep constant low temperature The product for civilian use of cold conditions.With the raising of quality of the life, consumer is to storing the fresh-keeping requirement of food also more and more higher, especially It is requirement to color and luster, the mouthfeel of food etc. also more and more higher.Therefore, the food of storage should also be as ensureing during storing, food Color and luster, mouthfeel, freshness of thing etc. keep constant as far as possible.It is only true in the market in order to preferably store food Empty fresh-keeping one kind.Through frequently with vacuum freshness retaining mode for vacuum bag is fresh-keeping and vacuum storing compartment is fresh-keeping.

Fresh-keeping using vacuum bag, consumer stores food and is required for progress to vacuumize action every time, and troublesome poeration cannot Consumer's likes.

It is fresh-keeping using vacuum storing compartment, because casing etc. is rigid structure, vacuum state is kept, to pumped vacuum systems Requirement it is very high, very high is required to the sealing property of refrigerator, an article is often picked and placeed, the new air poured into is more, and energy is disappeared Consumption is larger.Moreover, under vacuum environment, food reception cold is relatively difficult, is particularly disadvantageous for the storage of food.Further, since being Vacuum environment, user opens refrigerator doors etc. every time to be needed to take very big strength, causes user inconvenient for use.Although some refrigerators can By pumped vacuum systems to indoor ventilation between vacuum storing, but user can be so caused to wait long period, poor in timeliness.Very It is longer between space-time, it will also result in the deformation such as refrigerator body seriously, i.e., the existing refrigerator with Vacuuming structure can not be well Vacuum freshness retaining is completed, it is necessary to which the intensity of casing etc. is very big, realization requires very high, and cost is very high.

In addition, inventor has found：Because the equipment of making nitrogen for being conventionally used to controlled atmosphere is bulky, with high costs, lead Cause the technology be substantially also limited to use on various large-scale professional storages (typically at least 30 tons of storage capacity with On).It can be said that be only possible to economically to minimize Air-conditioning system using which kind of appropriate gas regulation technology and related device, Mute, makes it be applied to family or personal user, is that controlled atmosphere art personnel thirst for solving but all the time failing always The technical barrier that success is solved.

In some embodiments of the present utility model, be provided between drawer body 23 and drawer cylinder 22 locking device, Handle and handle positioning device.Locking device includes being arranged at the pivot lock of drawer end cap both sides, is arranged at drawer cylinder 22 On two buckling parts, and clamping promotes device.Each buckling parts can be projection.Clamping promotes device to can be used for promoting two Lock is pivoted to rotate towards the direction (i.e. respective first direction) for being connected in respective buckling parts.Handle horizontal extends, and Drawer end cap can be vertically slidably mounted on.Moreover, when drawer body 23 is closed, residing for handle Position can be the initial position of handle.And handle is configured in its initial position, its two ends pivots lock with two respectively and connect Touch against to prevent each pivot lock from being rotated along the other direction opposite with respective first direction, so as to pivot lock Button keeps mated condition with buckling parts, so that drawer body 23 is locked in into drawer cylinder 22.Further, when handle upwards or It is moved downward to releasing and keeps latched position, i.e., being moved to releasing from initial position keeps after latched position, can allow each pivot Twist lock button is rotated along the other direction opposite with respective first direction, to allow when pulling out drawer body 23, Pivot lock and rotate and depart from corresponding buckling parts, so as to allow to open drawer body 23.Handle positioning device be configured to when Hands movement makes handle keep at the position to after at each predetermined position, mainly initial position and releases and keeps lock Positioning is put.When opening drawer body, user first makes handle move to releasing holding latched position, handle positioning dress up or down Putting makes handle keep being in the position, and user can outwards pull open drawer body 23.When closing drawer body, user first makes drawer Body 23 is closed, then make handle downwards or on return to initial position, handle positioning device makes handle keep being in the position, from And make drawer body 23 and drawer cylinder 22 keep being in the lock state.

In order to further make the stable movement of handle, the two ends of handle are also respectively provided with guide rod and sliding block, guide rod Vertically extend.Drawer body 23 also includes two groups of slideways, the cunning that at least three, every group of slideway vertically extends Groove, so that the both sides of guide rod have a chute respectively, sliding block is moved on remaining chute, or distinguishes the both sides of sliding block With a chute, guide rod is moved on remaining chute.For example, every group of slideway may include before four chutes, guide rod Both sides have a chute respectively afterwards, and the both lateral sides (i.e. the left and right sides) of sliding block have a chute respectively.

So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model many Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the utility model spirit and scope The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new The scope of type is understood that and regarded as to cover other all these variations or modifications.
