The specific embodiment

To details of the present invention be described by accompanying drawing below.

Refrigeration appliance 1 is made of shell 11 usually, and this shell has rear wall 3.In shell 11, be provided with the single interlayer that is divided into by rack base plate 4.The cooler assembly 5 that has air interchanger 6 has been arranged in the bottom of refrigeration appliance.The interlayer that has rack base plate 4 is limited by dividing wall 2 in its back.Between the rear wall 3 of this dividing wall 2 and refrigeration appliance 1, constituted air duct 12.At the horizontal component of air duct 12, air duct is kept apart by a horizontally disposed dividing wall 21 and top interlayer.

Produce an air stream by air interchanger 6, air is sucked out and press subcooler assembly 5 from refrigerating chamber, air is cooled in this cooling unit, and above in the vertical part of air duct 12, pressing to.Air reaches the front side of refrigeration appliance at the top of refrigeration appliance through the horizontal component of passage 12, and falls there, and then air is sucked out and is transported to cooler assembly 5 in the refrigeration appliance bottom again by air interchanger 6.

Dividing wall 2 can be made by iron plate so far usually with carrying, and is furnished with perforation.At the top, dividing wall 21 also is to be made by the strong and firm iron plate of bearing capacity.The weight of refrigeration appliance has been enlarged markedly thus, makes the transportation of refrigeration appliance and adjust the position difficulty that becomes in ware room.Owing to assembled condensed water, dividing

wall

2,21 can be corroded, thus must apply corrosion-inhibiting coating, such as powder coating, be coated with baking finish and so on.Need more operation, this makes the manufacturing cost of this class dividing wall increase significantly for this reason.

Fig. 2 has shown a structure according to dividing wall of the present invention, and it is made of framework 7, and this framework has girth member 71 around the corner and cover 22 has been installed.Such framework 7 is very suitable to create with moulding material, aluminium moulding material particularly, and it is very light and can bear corrosion.Cover 22 is fixed on the framework 7 by upset and clip.Also can then adopt gluing in addition.Do not adopt gluing, cover just is easy to take off cleaning, just as normally used cloth cleans in the washing machine the inside.

Fig. 3 has shown a cover 23, and it is come out by a PVC thin film fabrication.Because this film is air-locked,, make it possible to achieve ventilation to cooling chamber so arranged perforation 24.Arrange the size of boring a hole and determining them according to the shaping situation of cooling chamber.For desired cold airflow, only superincumbent part arranges that perforation may suit.In the grid that the bottom of cooling chamber is separated by rack base plate 4, for each cooling interlayer is determined the size of perforation and arrange to suit, in this gas permeability that also can only perforation is set or determine on the top of cooling interlayer.

By using the cover of a textile, this class perforation can be in cloth by the processing of cloth manufactured come out, like this, subsequent handling has not just needed such as making perforation.Cloth should adopt the rayon thread manufacturing, just can produce satisfactory gas permeability by suitable syndeton.Certainly, also can syndeton be arranged to such as making the gas permeability at cover top be higher than the bottom here corresponding to the distribution or the mobile performance of cooling chamber.For cover, can not only adopt net, and can adopt knitted or woven fabrics.By the variation of Connection Density, also can not adopt special perforation structure, just can influence the gas permeability of cloth, to such an extent as to can satisfy ventilation requirement to the cooling interlayer.This can realize by selecting the silk thread material, also can realize by the silk thread mesh-density.Demonstrate special advantage at this weaving cover, because the manufacturing of textile cloth is very flexibly, cost is not high, and mobility status but also outward appearance in the not only desirable refrigeration appliance all are well suited for.

For fixing cover 22, can the reinforcing section that be used for fixing accordingly be set in its edge.But as shown in Figure 4, framework 7 is made of the section bar that longitudinally separates, and cover is sandwiched between two section bars branches compacted, has just realized in this way especially evenly still dismountable fixing.According to Fig. 4, framework 7 comprises a section bar 70, and it and framework divide and adopt bolting between the section bar 70 '.Between them,

cover

22 or 23 is firmly grasped by clamping.Another kind of form as shown in Figure 5, clamping plate 72 with

cover

22,23 by advancing section bar 7 and promptly.Adopt this form of implementation,

cover

22,23 easier being tensioned.If damage, cover also is easy to replace.

Describe the framework that has adopted an additional formation for dividing wall on the dividing wall at present, load onto a cover in the above.The dividing wall of Xing Chenging is insertable on refrigeration appliance like this, also takes out once more easily.Dividing wall 22 shown in Fig. 6 has frame section bar 70, and each dividing wall 22 herein all is installed between the support section bar 74 of refrigeration appliance and is fixed.One heat-insulating shield 31 is as the rear wall of this refrigeration appliance, be fixed on and support on the section bar 74, like this, in the width that supports section bar 74, formed an air duct 12, cold air rises in each air duct 12, just as described above, make progress by means of draught effect, enter the refrigeration appliance top.

Layout shown in Figure 7 has the following advantages, and has constituted a rear wall that runs through by means of cover in interlayer, and support section bar 74 is coordinated mutually with cover on color.The framework 7 of dividing wall 22 all is to border on mutually and be fixed on to support on the section bar 74.In addition, this arrangement form has such advantage, and promptly owing to bigger distance between rear wall 22 and the heat-insulating shield 31, air duct 12 has bigger cross-sectional area.

Dividing wall has been abandoned independent framework fully among Fig. 8.Each supports section bar 75 and has a groove 76, and cover is installed in wherein by clamping plate 73.So just saved vertical frame section bar.This dividing wall is very firm.

Dividing

wall

22,21 has been described as the wind deflector that comes out to enter the cold air at refrigeration appliance top from the cooler assembly in the front.Yet all dividing walls that can not carry can this mode create in the refrigeration appliance in principle, make that thus refrigeration appliance is very light and manufacture very cheap.These dividing walls can be shaped with the visibility region of simple mode at interlayer in addition, and as the propaganda purposes.Materials of different colors or film can be used as cover.
