Refrigerating plant with drawing and pulling type drawer

Technical field

The present invention relates to refrigerating plant, household refrigerating device especially, said device has the body and door that surrounds adiabatic storage compartment; And the drawer that can be drawn out from said storage compartment.

Background technology

This drawer perhaps a plurality of individually substantially self be arranged in the underside area of storage compartment; This means in the situation of the refrigerating plant that the user erects especially on the ground and must bend over downwards, thereby grasp the handle on the drawer and drawer pulled out.Substantially, drawer is by the plastics integral injection molding, and from stable reason, advantageously near the position fixing knob edge of drawer is located at this, and the antetheca and the bottom of drawer cross.The handle that is positioned at downside on the drawer that the storage compartment inner underside is settled makes the user when pulling out drawer, must further bend over, and this makes drawer use trouble.

Summary of the invention

The object of the present invention is to provide a kind of refrigerating plant, make the user be easy to touch drawer with push-and-pull drawer.

Refrigerating plant especially is understood that household refrigerating device, in other words is used for refrigerating plant, for example refrigerator or the combined refrigerator-refrigerator-freezer that family uses.About refrigerating plant, it can be frostless refrigerating plant, in this refrigerating plant, is blown into its inside storage compartments from the cold air of vaporization chamber, so that the cooling storage compartment.

At refrigerating plant, especially the household refrigerating device (its position that has the body that surrounds adiabatic storage compartment and door, the drawer that can be drawn out from storage compartment and be pushed into said inside storage compartments covers the shelf of said drawer), the handle bar that the object of the invention is achieved on the antetheca that is said drawer extends to before the leading edge of said shelf at least always.Particularly, the handle bar raise before the leading edge of said shelf.Because this arrangement, so the handle bar can be from touching, the same direction that will touch the inclusion of open-topped drawer subsequently from the user is definitely touched.Because the height of handle bar is settled, so reduced the degree that the user must bend in order to touch drawer.Preferably, in the position that is pushed into inside storage compartments, drawer is only partly covered by shelf, and its handle bar at least of drawer stretches out the leading edge above shelf.

The handle bar is particularly advantageous in a kind of like this situation of drawer, and this drawer is low frictionally to be guided in body on the telescopic rail, and therefore only needs relatively little power just can pull out.

That the handle bar preferably is set to isolate with the antetheca of drawer and fixing element on the edge above that.This means that the handle bar can easily make and have than the remarkable higher flexural strength of antetheca.Because handle bar thereby the required rigidity of the no problem of drawer operation caused remarkable contribution utilizes relatively little wall thickness manufacturing so the wall energy of drawer is enough with the mode of practicing thrift cost.

From the reason of simplifying, the handle bar preferably is clamped on the top edge of antetheca.

The handle bar preferably is made of metal, and this is from the former of high bearing capacity on the one hand thereby is the reason from design on the other hand.

The handle bar of being installed makes and can antetheca is designed on large tracts of land be transparent and also be smooth preferably, thereby the inclusion of drawer can be clearly seen on large tracts of land, and drawer need not to pull out.

The leading edge that in pushing the position, covers the shelf of drawer can be reinforced by means of clipping section bar equally.From the reason of consistent outward appearance, this section bar is preferably at least from the teeth outwards by forming with handle bar identical materials.Because the two in pushing the position near, so they look like an integral body to the user.

The section bar that is clamped on the shelf preferably includes downward-sloping web.On the one hand, this obviously helps the booster action of section bar, and on the other hand as subsequently more clearly, this web can interact with the handle bar, thereby is pushing position sealing drawer.

In order to guarantee to be easy to handle, grasp recess and preferably between the leading edge of handle bar and shelf, reserve.The user can be inserted into finger in this recess from the top, thereby at rear side grasp handle bar and pull it.

Grasping recess can extend in the whole width of drawer; This makes especially can make handle bar and section bar by cost by means of the mode of extrusion molding efficiently.

Alternatively, grasping recess can be in both sides by the protuberance gusset of handle bar.Because the leading edge of said protuberance and shelf forms labyrinth/labyrinth sealing, so they have played the effect of the inside of drawer and the isolation of storage compartment on every side and especially played the effect that limit air exchanges between drawer and storage compartment on every side.

Preferably, the handle bar comprises web, and the web of wherein said handle bar engages below shelf when pushing the position being in.This web can significantly be contributed the rigidity of handle bar and utilize minimized material consumption.In addition, prevent that object from falling in the drawer through the gap between the leading edge of handle bar and shelf.

In a preferred embodiment, drawer can be by means of the lid that carries above that by closely sealing.Like this, can the refrigerated item moisture evaporated of in drawer, storing be remained in the drawer storage life that this has limited the further evaporation of refrigerated item and has improved refrigerated item.

For lid when pulling out drawer still is positioned at inside storage compartments, said lid advantageously suspends from shelf.

Web on the handle bar, especially be in the supporting that the aforementioned web that below shelf, engages when pushing the position can also form lid.

Lid advantageously can be adjusted by height and position, this means that lid can keep separating with drawer if do not expect the deadend of drawer.

The slide block that is used to adjust the height and position of lid advantageously can be with the leading edge assembling along shelf of the mode that can adjust.
