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, locking device, handle and handle are provided between drawer 23 and cylinder 22 Hand positioner.Locking device includes two fastenings for being arranged at the pivot lock of drawer end cap both sides, being arranged on cylinder 22 Portion, and clamping promote device.Each buckling parts can be projection.Clamping promotes device to can be used for promoting two to pivot lock towards card The direction (i.e. respective first direction) for being connected to respective buckling parts is rotated.Handle horizontal extends, and can be vertically It is slidably mounted on drawer end cap.Moreover, when drawer 23 is closed, the location of handle can be the first of handle Beginning position.And handle is configured in its initial position, its two ends pivots lock with two respectively and contacted against, each to prevent Pivot lock to rotate along the other direction opposite with respective first direction, keep coordinating with buckling parts so as to pivot lock State, so that drawer 23 is locked in into cylinder 22.Further, locking bit is kept when handle is moved up or down to releasing Put, i.e., being moved to releasing from initial position is kept after latched position, and each pivot can be allowed to latch edge and respective first Other direction in opposite direction is rotated, to allow when pulling out drawer 23, is pivoted lock and is rotated the corresponding buckling parts of disengaging, So as to allow to open drawer 23.Handle positioning device is configured to after at the handle motion position predetermined to each, make handle Keep at the position, mainly initial position and releasing keeps latched position.When opening the drawer, user first make handle to Up or down moves to releasing and keeps latched position, and handle positioning device makes handle keep being in the position, and user can outwards pull open Drawer 23.When close drawer when, user first closes drawer 23, then make handle downwards or on return to initial position, handle is fixed Position device makes handle keep being in the position, so that drawer 23 and 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 23 is also including two groups of slideways, the chute that at least three, every group of slideway vertically extends, with Make the both sides of guide rod has a chute respectively, and sliding block is moved on remaining chute, or the both sides of sliding block is had respectively One chute, guide rod is moved on remaining chute.For example, every group of slideway may include four chutes, front and rear the two of guide rod Side has a chute respectively, 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.
