The specific embodiment

The housing of refrigerating plant is assembled by internal container and crust in the manner known to persons skilled in the art, wherein said internal container is by plastic sheet, for example pulled out by the whole deep-draw of polystyrene and form, shown in Fig. 1 perspective view, described crust is assembled by not shown sheet material.Each sheet material of not shown crust is connected to internal container 1 by bar elements 2 to 5, and wherein said bar elements 2 to 5 is joined together to form the framework of the front side of a closed interior container 1.

The sidewall 6 of internal container 1 is respectively equipped with a plurality of breakthrough portions 7, and described breakthrough portion is configured to receive backing spare (backing piece) 8.These backing spares act as flexible drawer type shelf that is used for internal container 1 or the suspension point of cooling off the article carrier substantially.

The breakthrough portion 9 of the big specification on the last back edge of internal container 1 and the backing spare 10 that will lay thereon for example are used for the sub-assembly of not shown inside light fixture or fan and light fixture is anchored at internal container 1.In the drawings, breakthrough portion 9 is around the continuous grain pearl 11 that the hot melt adhesive agent material is arranged.Near the same continuous extension 12 of this pearl extends to the front side of internal container along the upside of internal container 1.When the grain pearls 11 of extending around 9 in the breakthrough portion will be driven plain and form in this case potted line between the two between backing spare and internal container 1 when backing spare 10 emplaces, extension 12 was used to the fixing control cable or the cable 13 of powering.Cable 13 is connected to electronic control module with backing spare 10 in the device of assembling, be set up after the unshowned control panel that wherein said electronic control module is installed on top side bar elements 2.

With grain pearl 11 similarly but the ring of not shown hot melt adhesive agent material 7 is provided with around the breakthrough portion respectively, thereby form the sealing between backing spare 8 and the internal container 1.

Fig. 2 A to 2E shows each step of assembling backing spare 8.Fig. 2 A shows injection nozzle 4, draws the grain pearl of hot melt adhesive agent material under the control of described injection nozzle under manually controlling or at numerical control device around a described breakthrough portion 7.The hot melt adhesive agent material can be provided with the gas such as the pressurization of nitrogen, thereby when picking up nozzle 14, described hot melt adhesive agent material expand into the foam (closed-pore foam) of closed pore.Thereby the grain pearl 11 of the big volume of the few materials that obtained to use up.

With after forming a ring, shown in Fig. 2 B, backing spare 8 can be mounted in the sealing of grain integument.Backing spare 8 is illustrated as tube jar 15 for the purpose of simplifying in Fig. 2 B, described tube jar 15 is included in the annular lip 16 of extending around it, the open side of described tube jars 15 is towards the breakthrough portion 7, and in the ring around the open side, extend radially out breech lock hook portion 17, left a blank in the inboard of tube jar, in this case, be apparent that in the inboard of tube jar 15, can be provided with any given profile of the desired purpose that is suitable in refrigerating plant.

If the applying afterwards of a pearl 11 that be placed in of backing spare 8 just occurs soon, although then described grain pearl 11 still be heat with plasticity, but be enough to pushing backing spare 8 is passed breakthrough portion 7 and engages receptacle hook portion 17 on the edge of breakthrough portion 7, thereby grain pearl 11 is driven plain between sidewall 6 and flange 16, and has formed sealing.From the viewpoint of making, thereby more reasonably be on a plurality of breakthrough portions, at first to form grain pearl 11 conversely and consider that making hot-melt adhesive like this will cool off.For backing spare 8 is installed on breakthrough portion 7 then, a grain pearl 11 for example utilizes radiant heat or is heated once more by hot-air is directly blown on the pearl 11, and this is to finish before the laying of backing spare; Perhaps shown in Fig. 2 C, flange 16 is pressed to the heating once more of realization grain pearl on the pearl 11 by means of the hollow barrel-type instrument 18 of heat.If grain pearl 11 is foamed, then utilizing instrument 18 each plate of pushing of heat is to be worth especially; Because the hot melt adhesive agent material of foaming is the difference heat carrier, so the hot melt adhesive agent material of this foaming is reliably accurately fusing and become soft there in the place of its contact flange, thereby any uneven thickness in the periphery of grain pearl 11 is homogenized and obtain to contact between flange 16 and a pearl 11---and thereby obtain desired sealing effectiveness---in the whole periphery at flange 16.

As the precaution measure, shown in Fig. 2 D, the hot melt adhesive agent material can be injected on the sidepiece that deviates from sidewall 6 of flange 16 and is injected on the zone of adjacent flanges 16 of sidewall 6 then by means of nozzle 19, thereby forms second sealant 20 shown in Fig. 2 E by this way.As applying of the grain pearl shown in Fig. 2 A, this operating process also is easy to automation and realizes.Thereby, even flange 16 and the hot-melt adhesive that at first is applied to its grain pearl 11 are not realized the sealing in the whole periphery of flange 16, also guaranteed the sealing of breakthrough portion 7.

The embodiment of the simplification of the method according to this invention is also contemplated that not apply a pearl 11 in advance and to be ejected into other direct breech lock of mode or connection backing spare on the sealant 20 subsequently.

Undoubtedly, the installation of backing spare 10 can be finished at backing spare 8 identical modes with above-mentioned.

Fig. 2 show internal container 1 and by partial sectional view continuous, that seal hot melting adhesive grain pearl 11 is attached to the backing spare 10 of described internal container.The cable 13 that extends to controller module 13 from backing spare 10 is not fixed by continuous grain integument, but hot-melt adhesive distributes on internal container 1 with the form of independent drop 21 desirable path along cable 13, and cable 13 is attached, wherein this cable is pressed into step by step owing to applying and is still in each drop 21 heat or that reheat and therefore plastify, as mentioned above.Cable 13 by this way on internal container 1 by enough anchorings securely, thereby still firmly in place when in installation steps subsequently, utilizing heat-insulating material to foam by the cavity volume that each plate limited of internal container 1 and crust.

Install on internal container 1 by means of hot-melt adhesive equally with the evaporimeter 26 that internal container among Fig. 1 illustrates separately.Fig. 4 A to 4D shows this point in the mode of one group of cutaway view of the rear wall 27 of process internal container.It is own that Fig. 4 A shows rear wall 27.In Fig. 4 B, one deck hot-melt adhesive is applied on the rear wall 27, this by with described hot-melt adhesive brush or be sprayed on the rear wall and realize.In Fig. 4 C, evaporimeter 26 illustrates with hot-melt adhesive layer 28 on the rear wall and contacts.Evaporimeter with can be preheated before layer 28 contacts, thereby layer is melted.Because the curvature of rear wall 27---exaggeration illustrates in the drawings, is pressed onto side so the middle section of evaporimeter 26 at first contacts with hot-melt adhesive layer 28 and begins then with described hot-melt adhesive layer fusing and with it.This means that the contact area between evaporimeter 26 and the layer 28 is extended in the process of handling is installed, and rear wall 27 is according to the cross section of evaporimeter and bending simultaneously flattens, and the air between rear wall 27 and the evaporimeter 26 is forced to be transported to the edge of evaporimeter 26.Guaranteed by this way between evaporimeter 26 and the adhesive phase good, the surface contact and thereby has guaranteed hot efficiently transmission between the inboard of evaporimeter and internal container completely.

A part of length of the refrigerant lines of not shown evaporimeter 26 can be by being attached to rear wall 27 such as the continuous grain pearl of the hot-melt adhesive of the extension 12 of Fig. 1 or by the independent spot such as the spot 21 of Fig. 3.
