This drawer substantially individually or multiple self be arranged in the underside area of storage compartment, this means must bend over downwards in the situation of the refrigerating plant that user erects especially on the ground, thus the handle grasped on drawer drawer is pulled out.Substantially, drawer is by plastics integral injection molding, and for the reason of stability, advantageously at the adjacent edges position fixing knob of drawer, at this place, antetheca and the bottom of drawer cross.The handle being positioned at downside on the drawer that storage compartment inner underside is settled makes user must bend over further when pulling out drawer, and this makes drawer use trouble.

Summary of the invention

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

Refrigerating plant is especially understood to household refrigerating device, the refrigerating plant in other words used for family, such as refrigerator or combined refrigerator-refrigerator-freezer.About refrigerating plant, it can be frostless refrigerating plant, and in this refrigerating plant, the cold air from vaporization chamber is blown into its inside storage compartments, to cool storage compartment.

Refrigerating plant, especially household refrigerating device (it has the body and door, the drawer that can be drawn out from storage compartment and the shelf covering described drawer in the position being pushed into described inside storage compartments that surround adiabatic storage compartment), before the object of the present invention handle bar be achieved on the antetheca being described drawer at least extends to the leading edge of described shelf.Particularly, handle bar raise until described shelf leading edge before.Due to this arrangement, so handle bar can touch from above, from user, the same direction touching the inclusion of open-topped drawer is subsequently touched definitely.Because the height of handle bar is settled, so reduce the degree that user must bend over to touch drawer.Preferably, in the position being pushed into inside storage compartments, drawer is only covered by shelf portion, and at least its handle bar of drawer extends over the leading edge of shelf.

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

That handle bar is preferably set to isolate with the antetheca of drawer and fixing on edge thereon element.This means that handle bar easily can manufacture and has higher flexural strength more remarkable in antetheca.Rigidity needed for thus handle bar operates the no problem of drawer causes remarkable contribution, so the wall energy of drawer is enough utilize relatively little wall thickness manufacture in cost-saving mode.

For the reason simplified, handle bar is preferably clamped on the top edge of antetheca.

Handle bar is preferably made of metal, and this is that another aspect is the reason for design for the reason of high bearing capacity on the one hand.

The handle bar installed makes it possible to front wall design to become to be transparent over a large area and to be also preferably smooth, thus the inclusion of drawer can be clearly seen over a large area, and drawer is without the need to pull-out.

Can be reinforced by means of clipping section bar equally at the leading edge pushing in position the shelf covering drawer.For the reason of consistent outward appearance, this section bar is preferably made up of the material identical with handle bar at least from the teeth outwards.Because the two push in position near, so they look like an entirety to user.

The section bar be clamped on shelf preferably includes downward-sloping web.On the one hand, this obviously contributes to the booster action of section bar, and on the other hand as subsequently more clearly, this web can interact with handle bar, thus closes drawer pushing position.

In order to guarantee to be easy to handle, grasp recess and preferably reserve between handle bar and the leading edge of shelf.Finger can be inserted in this recess from top by user, thus pulls it at rear side grasp handle bar.

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

Alternatively, grasping recess can in both sides by the protuberance gusset of handle bar.Because the leading edge of described protuberance and shelf forms labyrinth/labyrinth sealing, thus they serve the effect isolated in the inside of drawer and storage compartment around and especially serve limit air drawer and around storage compartment between the effect that exchanges.

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

In a preferred embodiment, drawer can be tightly closed by means of the lid carried thereon.Like this, by the water tariff collection of refrigerated item evaporation that stores in drawer in drawer, the further evaporation of refrigerated item can be which has limited and improves the storage life of refrigerated item.

In order to when pulling out drawer, lid is still positioned at inside storage compartments, described lid advantageously suspends from shelf.

Web on handle bar, the aforementioned web especially engaged below shelf when being in and pushing position can also form the supporting of lid.

Lid advantageously can height and position adjustment, this means that lid can keep separating with drawer if the deadend of undesirably drawer.

Slide block for adjusting the height and position of lid advantageously can assemble with the leading edge of the mode that can adjust along shelf.

Evaporimeter 8 and fan 9 is held in known manner in vaporization chamber 4.When fan 9 operates, air is drawn in vaporization chamber 4 from storage compartment 5 via the opening 10 in the leading edge of supporting plate 3 by this fan, there, air contacts with evaporimeter 8 and cools, and fan impels the air of cooling to enter in distribution pipeline 11, wherein said distribution pipeline in the rear wall of body 1 to downward-extension.Multiple outlet openings 12 in distribution pipeline 11 at various height place are passed in storage compartment 5; The outlet opening 13 of lower side is passed in holder 7 in the below of shelf 6.The inclusion of drawer 14 is cooled by the air-flow from outlet opening 13 substantially, the passage 16 of wherein said air-flow through extending between shelf 6 and the lid 15 of closing drawers 14.

Identical arrangement also can adopt in cold wall refrigerating plant, the directed lid through push-and-pull drawer 14 of the air-flow wherein cooled by the evaporimeter be embedded in the rear wall of body and the passage between the shelf of the described side of covering.

The drawer 14 that flexible slide rail 19 guides is shown in Figure 1 is in two positions, i.e. the one side stop position be pushed in holder 7 shown in dotted line; And on the other hand as shown by the solid line whole drawer 14 be positioned at the pull-out location before the leading edge of shelf 6.

The single-piece of the drawer 14 of substantial rectangular box shape or the primary element of multi-piece type primary element, especially injection-moulding plastic are horizontal bottom sections 20; Antetheca 21; (slightly lower than antetheca 21) rear wall 22; And the sidewall 23 of connecting wall 21,22, wherein each sidewall has towards the evenly downward-sloping top edge 24 of rear wall 22, and each sidewall has the step 25 of the corresponding flexible slide rail 19 of accommodation one.

Reinforcing element 26 is clamped on the top edge of antetheca 21.Reinforcing element 26 can be set to the section bar of extrusion molding, and this section bar has U-shaped section, and the groove under shed of wherein said section is assembled by CONTACT WITH FRICTION, snap lock or the mode of bonding is clamped on antetheca 21; This section bar also has substantially horizontal web 27, and it evenly extends with top edge 24 above bottom section 20, and termination part, and described termination part is in the end of the closed at both ends groove of section bar; Be also contemplated that by means of the integrally manufactured whole reinforcing element 26 with termination part of injection molding mode.

Drawer 14 be in push stop position time, reinforcing element 26 together defines the groove 28 of upward opening with the leading edge of shelf 6, and wherein user can grasp this groove from top, to be pulled out by drawer 14.The web 27 that the direction contrary with the pull-out direction just worked is stretched out is that reinforcing element 26 gives very large flexural strength, this means that pulling force is incorporated in the main body of drawer 14 in the whole width of antetheca 21 with being distributed.

Lid 15 is suspended from shelf 6 by means of the hook portion 33,34 interlocked and eyelet (eye) 29,30, and wherein said hook portion and described eyelet are arranged at four adjacent corner of described shelf 6 and described lid 15 respectively.Each eyelet 29,30 comprises vertical channel 31, and hook portion 33,34 joins in described vertical channel with having down suction, thus lid 15 can vertically and non-horizontally moves.Cover 15 and be shown in Figure 1ly in rest position, at this rest position, described lid is not supported by drawer 14 but is only kept by shelf 6.Hook portion 33,34 lays respectively at the lower end of groove 31.As shown in the figure, this rest position is lower than the extension of top edge 24 of sidewall 23 being in the drawer 14 pushing stop position, and the gradient being in the lid 15 of this rest position is greater than the gradient at edge 24.Because leading edge 17 position of lid 15 is higher than the top edge of rear wall 22, so drawer 14 slides in holder 7 below lid 15 smoothly when being pushed into, and only lucky before reaching and pushing stop position, and drawer contacts and raises lid 15.Because the gradient of lid 15 is greater than the gradient at edge 24, so the top edge contact lid 15 of initial only rear wall 22, and proceed to move inward along with drawer 14, first lid 15 is tilted.Only when covering the gradient of the top edge 24 being lifted to the gradient coupling sidewall 23 being enough to make to cover in rear region, between edge 24 and lid 15, just there is achieving full-area contact.Reached it in drawer cabin when pushing stop position, the top edge of the wall 22,23 of drawer 14 contacts lid 15 with the rear region of web 27, to make the inside of drawer with air-tightness substantially and the mode of resistance to movement is closed.

Thus, due to the evaporation of refrigerated item comprised in drawer 14, can position is higher than the storage compartment 5 of surrounding in drawer humidity, the air of wherein said inside storage compartments around dries out owing to contacting with evaporimeter 8.Thus the dehydration this reducing refrigerated item also improves the storage life of refrigerated item.

Fig. 3 shows these situations, and this is by means of the amplification view of the front upper edge of drawer 14, lid 15 and shelf 6.Can find out, the leading edge of shelf 6 is reinforced by clamping section 35 thereon, and this section bar 35 is made of aluminum and/or have the surface finish identical with reinforcing element 26 as reinforcing element 26.Front eyelet 29 is clamped to the end of section bar 35.In Fig. 3, unshowned rear eyelet 30 is the parts of the section bar 18 be clamped in the back edge of shelf 6.From the critical piece of the leading edge of the support shelf 6 of section bar 35, rib 36 stretches out downwards obliquely, and just in time stops above web 27.Smooth border (marginal) district 37 of lid 15 is in rib 36 rear support on web 27, thus possible the moving both vertically of lid 15 is not subject to rib 36 and hinders.

Frontier district 37 extends on all four sides of lid 15 around center 38.Although frontier district 37 be smooth thus be closely bearing on web 27 or sidewall 23 with on the top edge 24 of rear wall 22, center 38 can be bending, thus adds the flexible rigidity of lid 15.

Fig. 4 shows the shelf 6 of the second embodiment, covers the perspective view similar with Fig. 2 of 15 and drawer 14.Be slide block 39 with the most obvious difference shown in Fig. 2, wherein said slide block fastens on the section bar 35 of reinforcement shelf 6.Fig. 5 shows the perspective view tiltedly looked over from below, i.e. a part for the battery limit (BL), front 37 of this slide block 39 and lid 15, but is omitted shelf 6 and section bar 35.Slide block 39 comprises three wall elements 40,41,42, and they, integratedly each other in being connected squarely, are similar to asymmetric U-section, in assembled state as shown in Figure 4, before described wall elements is bearing in section bar 35, on upper and rear side.The web 43 stretched out forward from wall elements 40 can be used as the holding part adjusting slide block 39; But this web can also form a pointer, such as, the scale in the top edge being impressed into reinforcing element 26 in conjunction with time, this pointer realizes the qualitative evaluation of slide position.The sidepiece contrary with web 43 of wall elements 40 forms finger 44, and wherein in complete assembled state as shown in Figure 4, described finger and wall elements 41 extend through the gap in rib 30 abreast below shelf 6.The end section 45 that the oblique angle of finger 44 is downward engages in the groove 46 of lid 15, and wherein said groove 46 points to obliquely relative to the leading edge of described lid.Because end section 45 engages in groove 46, so slide block 39 impels lid 15 moving along body 1 in downward direction along the adjustment of the longitudinal direction of section bar 35.

Be not both opening 47 with the second point of embodiment as shown in Figure 2 and replace perpendicular elongate groove 31 in eyelet 29,30, wherein said opening 47 simultaneously along the vertical of body 1 with in downward direction extend, and there is the feather edge of surface thereof forward, the hook portion 33 of lid 15 is sat idly on each feather edge.The inclination extension of feather edge result in lid 15 and is associated with movement vertically along the movement controlled by slide block 39 in downward direction.In other words, by being positioned properly slide block 39, user can cancel the close contact of lid 15 and drawer 14 and set gap between, and the width in described gap depends on the position of slide block 39.Therefore the cold air of discharging from opening 13 no longer only flows through passage 16, but greater or lesser extent also flows through the inside of drawer 14.Therefore, if necessary, too much moisture can be discharged from drawer 14, and water condensation and make the danger that the inclusion of drawer 14 is soaked on the inner surface of drawer 14 when the refrigerated item can eliminated in drawer 14 is too much evaporated.

About this embodiment, identical with as shown in Figure 2 except the scale contrary with web 43 of reinforcing element 26.

Fig. 6 shows the perspective view of shelf 6, lid 15 and drawer 14 according to the 3rd embodiment.In this embodiment, the height and position covering 15 is arranged to non-adjustable; But the opening 47 of the eyelet 29 of the end of section bar 35 has form as shown in Figure 4, this is because this form is easily compatible with the operator scheme with reference to the lid 15 described in Fig. 2.For the reason simplified, therefore it is possible that different device model is manufactured with and does not have adjustable for height lid 15, think that all models adopt identical eyelet 29.

Reinforcing element 26 is manufactured to injection-molded parts integratedly at this.This makes it possible to the length of the groove 28 reducing the width traversing body 1.On the both sides of groove 28, protuberance 48 is formed on reinforcing element 26, and wherein said protuberance stretches out and abuts against section bar 29.Fig. 7 shows the sectional view of the front upper edge of drawer 14, lid 15 and shelf 6 in the plane extended through one of them protuberance 48.The rear wall 49 of the protuberance 48 of hollow has the slope tilted a little, and it is parallel to the front side of section bar 35, and in an acute angle with web 27 shape, and the rib 36 stretched out of section bar 35 engages in this acute angle.Reinforcing element 26 and section bar 35 are thus complimentary to one another at the At The Height of protuberance 48, thus form one labyrinth/labyrinth sealing, then it prevent air-flow through the inside of drawer 14, though lid 15 or drawer 14 such as owing to transshipping the close contact at the deform ation prevention that the causes part place therebetween in their places.
