Description

Refrigerating appliance

Background technology

Refrigerating appliance for example refrigerator, refrigerator, freezer machine assembly etc. has shelf, and for example storage trays, gripper shoe, depositing basket etc. cool off article and can leave in the described shelf.Some shelves or all shelves in the shelf particularly can be implemented as the glass shelf, type portion at least forwardly or the rear portion be assembled on the described glass shelf.Before the edge of type portion cover glass, back type portion can project upwards, and is pushed rear wall by refrigerating appliance to prevent to cool off article, touches this wall and is frozen on it.In some cases, the drawer that these shelves or storage shelf can be similar on the sidewall that is attached to refrigerating appliance is pushed into or pulls out, to guarantee more easily near the cooling article.

The existing method that realizes the drawer type Drawing-out rack is to use the telescopic pull-out element with metal rail.The example of this telescopic pull-out element is described among the DE102006018203A1.These telescopic pull-out elements have high quality, but very expensive the manufacturing.In the solution of lower cost, by plastic frame around glass plate or plastics shelf between the grooved accommodation section on the sidewall of refrigerating appliance, slide usually, the guiding piece of plastic frame is served as in the described accommodation section.Yet this solution moves stone.In addition, too heavy in these drawing structure reality, and in refrigerating appliance, take big quantity space.

Summary of the invention

The purpose of this invention is to provide a kind of like this refrigerating appliance, described refrigerating appliance has the drawer type Drawing-out rack, described Drawing-out rack is supported for and makes them to slide on sidewall, especially make the storage trays low cost, reliably, not rude and reposefully the operation.

Above-mentioned purpose realizes by a kind of refrigerating appliance with feature of claim 1.

According to the present invention, keep protuberance to show identical height greatly and be arranged on the sidewall, described maintenance protuberance is when being spaced apart from each other when depth direction is watched, and is bonded on the shelf from the below, and support shelf by this way, and shelf can move on described maintenance protuberance.Shelf also has at least one induction element on the edge, described induction element only extends on a part of length of the total depth of the inner bag of refrigerating plant, and when shelf is inserted into, be bonded on keep in the protuberance, especially the back keeps in the protuberance.Be positioned at the free degree that moves upward of two edge side induction element restriction shelves on the shelf, also limit the free degree that moves downward if desired, thereby prevent that it is at an angle especially with its pull-out direction or push direction slippage vertically, prevent when pull that promptly it is inclined upwardly, prevent to exceed predetermined pull zone at least.Described at least two that are separately positioned on the relative sidewall keep protuberance can especially be implemented as very simple plastic components, and support shelf.The preferred corresponding induction element that can be implemented as simple plastic components equally in the horizontal, especially limit the locomitivity of shelf on the maintenance protuberance with the horizontal support position of shelf with meeting at right angles, thereby when by pull, make shelf guide with horizontal direction.Only be constrained to sub-fraction length by the degree of depth yardstick that will keep protuberance accordingly for the total depth length of corresponding sidewall, make sidewall can be designed on the major part on its surface smooth or smooth.This means that shelf, rather than is held on its lateral edges along its entire depth length along the guiding of the side directed element of its respective edges by correctly, described induction element only extends along the part of the total depth length of shelf.This means that it can be moved reposefully, the danger of tumbling reduces, thereby also can reduce to damage the danger of sidewall.In addition, have short induction element (watching) along depth direction sidewall especially if it has smooth or flat design, then easier cleaning visually also has more attraction.If less from the maintenance protuberance that sidewall comes out, then the whole inside of refrigerating plant also has bigger sensation.Therefore, the interaction of the holding element on the sidewall of induction element on the shelf and refrigerating appliance provides complete function enough concerning Drawing-out rack.

If especially corresponding shelf keeps freedom promptly not have induction element and margin guide element only along rear section length setting along the forward part length of its entire depth yardstick, then, for shelf, produced the profile that does not almost have body side frame when when the front portion is watched.If especially the cover cap bar is saved at the front edge place of the shelf of horizontal expansion, then the exterior contour form of shelf feels not have framework on the whole.If glass plate is as shelf, then this structure is especially favourable.

Preferably, corresponding induction element is along the extremely mostly extension of the entire depth length of the long side edges of shelf.

According to a favourable improvement, keep protuberance to be implemented and to be arranged to: the shelf that side direction is supported by them rests on 2 at least, the degree of depth of described 2 shelves that are spaced apart from each other over half.In addition, the holding point that the back keeps protuberance preferably with the spaced apart setting of rear wall, spaced apart distance is roughly corresponding with the pull degree of depth of shelf.This guarantees shelf, and keep will be supported well all the time on the protuberance as long as it rests, even it is promoted by back forward or mutually.

Thereby in the embodiment of especially can be at low cost especially advantageously realizing, keep protuberance when the sidewall deep-drawing of refrigerating appliance by drawing and moulding to the sidewall of refrigerating appliance.Erect image is used for the retainer of the fixed-site shelf of the overwhelming majority, and these maintenance protuberances according to the present invention are moulded in the manufacture process of sidewall simply; Thereby can avoid other mounting cost.In order to make this become possibility, keep protuberance to be configured to the simple geometric shape, for example semilune or circle section shape.

Preferably, keep protuberance to implement with curved shape; They are outstanding from sidewall as boss.This has satisfied the requirement of manufacture process, and the danger of the weak spot that produces can be in the molded and shaped process of rectangle protuberance.In addition, the warp architecture of protuberance simplifies the setup the importing of the induction element on shelf.At this, the design of the semilune of preferred boss.This especially easily molded and easily the cleaning.

Preferably, in the maintenance protuberance on each sidewall each has spacer portion, and described spacer portion is arranged on the sidewall, and keeping projecting upwards on the protuberance above the guiding surface, shelf rests on the described guiding surface, does not directly contact with sidewall thereby shelf self is held in.This means that when mobile, shelf is not to slide along sidewall, but only slides on spacer portion, therefore, compare easier moving on whole sidewall, can prevent to damage sidewall in addition than the situation that it slides.During spacer portion can play a part shelf decided in addition, and demoulding tapering or other dimensional tolerances of any wall inner bag and/or corresponding shelf of compensation cooling article container.

In an advantageous embodiments, guide rail is arranged on the sidepiece of shelf, and described guide rail is preferably being wrapped the corresponding protuberance that keeps in every side, makes when shelf moves, and keeps protuberance to slide along guide rail.Preferably, corresponding guide rail only is attached on the shelf along the part of the total length of the lateral edges of corresponding shelf and (watches along depth direction).Especially, corresponding guide rail only on depth direction along the part setting of the Background Region that is arranged in refrigerating appliance, the especially inner bag of family expenses refrigerating appliance of the long side of shelf.If guide rail only as along a rear portion side edge section hold part be arranged on the shelf and only the back keep protuberance in this rear portion side edge section, to move promptly being supported for the permission sliding motion, this is especially favourable.Guide rail is preferably respectively along the rear section section setting of the lateral edges of shelf and be arranged in back maintenance protuberance on the sidewall of inner bag and move at horizontal pull and move along guide rail, this means that shelf especially advantageously is fixed on and prevents its rotation up and down or the position of the motion of tumbling.Owing to guide rail keeps moving on the protuberance in the back respectively, therefore avoided widely preferably being worn and torn by shelf itself by the molded maintenance protuberance of identical plastics and then grinding away with the corresponding inwall of inner bag.Preferably, select plastics or metal for corresponding guide rail, particularly described plastics or metal have low coefficient of friction.When using glass plate as shelf, this has been avoided shelf to keep protuberance directly to slide contiguously with the back on edge side and has made these edge side wearing and tearing.If especially guide rail is installed in the rear portion side fringe region of shelf, then these guide rail mean, shelf is directed in the motion of its pull, though make weight be positioned at anterior it can not be in the rear wall disengagement of upwards tumbling, even or weight be positioned at the rear portion and can not tumble downwards at the rear portion.For this reason, guide rail is by touching on the downside that keeps protuberance.

The length of corresponding guide rail is preferred to be similar to corresponding with the length that each shelf can move forward on pull-out direction at the most.This guarantees that shelf is directed, thereby prevents to tumble in whole pull motion process.In order to remove shelf, shelf keeps protuberance before making guide rail be lifted to cross advantageously forward and upwards lifting, especially keeps boss, and can be kept protuberance, especially keep boss to pull out from the back.Having only at this moment, shelf just can be removed.

In another preferred embodiment, have two guide rail each intervals to turn up the soil on the both sides respectively to be arranged on the lateral side edges of extending along depth direction of shelf, described guide rail is bonded on respectively in one that keeps in the protuberance.By a guide rail of on forward and backward maintenance protuberance, moving respectively, can avoid widely keeping producing wearing and tearing on the protuberance, these wearing and tearing are owing to for example glass plate keeps the friction on the protuberance to produce at plastics.In case the space between the guide rail guarantees that shelf just is drawn out and can remove shelf simply, this be because preceding maintenance protuberance remove the position can be by the space between the guide rail that is spaced apart from each other on the depth direction.In this way, can wholely spur shelf forward and remove it.

In addition, in a preferred embodiment, preferred laterally disposed protuberance is attached to shelf, and when shelf was drawn out, the protuberance touching was arranged on the stop element on the refrigerating appliance, and described stop element preferably is implemented in and keeps protuberance in them.These very simple and cheaply combination of elements can realize the complete function of high-quality pull with low manufacturing cost.The protuberance that serves as backstop on the shelf is configured to: when shelf was drawn out, its touching was located at backstop on the refrigerating appliance, especially keeps protuberance they oneself.These three the very simple elements of implementing, keep protuberance, induction element and backstop protuberance, interaction can in refrigerating appliance, realize cheaply, Drawing-out rack, this had both prevented when pulling out that shelf from upwards tumbling and had prevented also that shelf from dropping downwards, and easy operating.

In a preferred embodiment, backstop is positioned at the rear portion of shelf.When shelf was pulled out fully, corresponding protuberance, the especially back of keeping of its touching kept protuberance.Thereby preventing that shelf is drawn out to surpass, this makes it be positioned at the point that keeps on the protuberance reliably to prevent to tumble forward.Preferably, rear side backstop is identical with spacer bar, and described spacer bar is arranged on the rear portion of shelf, to prevent to leave in cooling article on the shelf by the rear side that contacts refrigerating appliance and be frozen in the there.Back spacer bar is designed to make it to can be used as backstop, and this makes it possible to save the assembling of another additional backstop.Therefore, back spacer bar has dual-use function.

In another favourable embodiment, itself serves as backstop guide rail.For this reason, guide rail is bonded on the maintenance protuberance that is arranged in the rear portion in the pull motion process, and has only when the pull motion finishes fully, keeps protuberance before it just reaches.Thereby, can not discharge the back guide rail keeps protuberance before its touching before and keep protuberance.Before keep protuberance, promptly preferably differently be shaped with the back protuberance with the immediate protuberance of door, make it in guide rail, not slide by similar back protuberance.Keep protuberance before guide rail touches, thereby preventing that shelf is drawn forward out too tumbles far and downwards.Therefore, keep corresponding shelf, for example glass plate that its spacer portion away from sidewall preferably is arranged on the preceding maintenance protuberance, then keep protuberance not have this spacer portion.In this case, the guide rail touching is provided with fore holding member, and in this case, these holding members have also makes whole solution have the dual-use function of lower cost.If shelf will be removed fully, it must lift forward a little, move and make it further pull out forward so that guide rail is crossed backstop, thereby it discharges corresponding back at this moment and keeps protuberance.

At last, should also be pointed out that, following technical scheme does not exceed scope of the present invention: all induction elements of Drawing-out rack and holding element are not arranged on the sidewall of refrigerating appliance itself, and be arranged on the midfeather that serves as sidewall in the refrigerating appliance, for example, described midfeather also can be the wall that is molded on the shelf.
