Description

Refrigerating and freezing appliances {REFRIGERATING AND FREEZING APPLIANCE}

The present invention relates to a refrigerator and a freezer unit including a throughgoing inner container, which are flexible and rigid without any joining lines or kinking edges and are integral with each other. And a freezer compartment and a refrigerator compartment connected to each other, and a refrigerator and a freezer unit forming an evaporator located in the freezer compartment.

Refrigerators and freezer units, including through-type inner containers, generally consist of one-door mechanisms and are advantageous in many respects. Without separation of the freezer compartment, no dirt-collection edge is revealed between the freezer compartment and the chilled goods container. For refrigerators and freezer units that include separate inner containers or separate freezers a more improved appearance can be obtained. Moreover, refrigerators and freezers comprising a penetrating internal container eliminate the need for complicated and / or costly sealing measures when installing the evaporator.

As long as the flow-through inner container is made flexible and rigid in the transition region between the freezer compartment and the refrigerating compartment in the apparatus, it is proved that the installation of the evaporator is difficult due to the loose space. There is often only a small gap between the freezer compartment and the refrigerator compartment. Therefore, conventionally, U-shaped plate evaporators have been used in instruments with a penetrating internal container, which is used to fix the freezer compartment from the backside in the manner of a clip. By pushing over, the evaporator contacts the rear wall of the freezer compartment and two opposed side walls. However, the cooling performance of this arrangement is limited.

In order to achieve more efficient cooling of the freezer compartment, some, through-hole structure of the inner compartment has often been lost in terms of more efficient use of the evaporator. In particular, the provision of a separate sheet metal box as an evaporator barrel has already been proposed, in which evaporator pipes covered with aluminum tape are wound around the evaporator barrel. This prefabricated box can be installed in a freezer compartment separate from the conventional refrigerating compartment, but this requires a splash frame for installation, leaving the freezing compartment sealing and the mounting ends visible in the inner container. Therefore, this solution is not satisfactory in light of recent trends.

Therefore, the basic object of the present invention is to provide an improved refrigerator and freezer including the flow-through inner container as mentioned above, so that the freezer compartment can have a more efficient cooling effect, and a cooler including the flow-through inner container and The advantage of the freezer unit is related to the more efficient freezer freezing effect.

This object is solved by a refrigerator and a freezer according to claim 1 of the present invention. Preferred forms of the invention are subject of the dependent claims.

According to the present invention, a wound box evaporator is provided as an evaporator, regardless of the installation state into a through-type inner container having a freezer compartment connected to the refrigerating chamber in a flexible but rigid manner despite the difficulty of securing free space. It is provided as an evaporator that surrounds the freezer compartment with four sides. Compared with the U-shaped plate evaporators used in the prior art, the wound box evaporator extends like the four sides surrounding the freezer compartment, so that the freezer compartment face disposed against the cold compartment is spaced from the refrigerator compartment by only a narrow gap. As a result, high efficiency can be obtained. Even without a very expensive compressor, the freezer's function is greatly improved, resulting in higher climb ratings. Thus, the present invention can only be used in refrigerators and freezer units comprising only a specific type of evaporator, in particular a U-shaped plate evaporator, a through-type inner container connected to the refrigerator compartment by means of bending rigidity integrally molded freezer compartment. It is the first time to eliminate prejudice. With the provision of a wound evaporator box according to the invention, the advantages of a refrigerator and a freezer comprising a flow-through inner container are combined with the high cooling efficiency of the freezer compartment.

Preferably the evaporator is arranged firmly attached to the freezer compartment. The evaporator, so-to-say, can be positioned in a light press-fit to the freezer compartment, so that the winding coil of the evaporator located in a shape adapted to the freezer compartment is in front contact ( By achieving full contact, more desirable heat transfer is achieved.

In still another aspect of the present invention, the evaporator is attached to the freezer compartment. The wound box evaporator may in particular be connected to the freezer compartment by an adhesive tape adhering on both sides or a corresponding adhesive film. The double-sided adhesive tape can, on the one hand, be connected with a heavy-duty and on the other hand eliminates the setting time often found in other adhesives.

The wound evaporator pipes of the wound box evaporator may generally be located directly in the freezer compartment. However, preferably, plates, in particular metal plates, are arranged between the freezer compartment and the winding pipe of the evaporator so that the evaporator winding of the evaporator is applied to the plate. Preferably the inner surfaces of the plates are bonded to the freezer compartment of the inner container as described above. Metal plates between the winding shape of the evaporator and the freezer compartment enable heat transfer from the freezer compartment to the entire area.

The refrigerator and freezer units consist in particular of one-door appliances, the doors of which extend beyond both the refrigerator compartment and the freezer compartment. In this connection, the opening cross-section of the freezer compartment may be offset backward relative to the refrigerator compartment, ie towards the rear of the appliance. In this type of mechanism, the gap between the freezer compartment and the refrigerating compartment may extend to less than 4/5 of the depth of the inner container.

The present invention is explained in more detail through the following embodiments and related drawings. In the drawing:

1 is an overall conceptual perspective view of a refrigerator and a freezer according to an embodiment of the present invention.

Figure 2 is a side and rear perspective view of the inner container of the refrigerator and the freezer of Figure 1 showing a wound box evaporator located in the freezer compartment of the inner container.

3 is a front view of the inner container of the refrigerator and the freezer of the preceding figures.

1 shows a one-door refrigerator and freezer unit 1 in which the door 2 of the appliance extends all over the front to cover both the chilled goods container 3 and the freezer compartment 4. ). As shown in FIG. 1, the freezer compartment 4 is substantially smaller than the refrigerating vessel 3 and is arranged on top of the refrigerating compartment, as is known.

As shown in Figs. 2 and 3, the refrigerator and freezer unit 1 has a through-type inner container 5 made of plastic in a suitable manner. The inner container 5 is integrally made into one and comprises both a freezer compartment trough defining the freezer compartment 4 and a refrigerating compartment 7 adjacent to the refrigerating vessel 3. As shown in FIG. 2, the freezer compartment 6 is only separated from the refrigerating compartment 7 into a gap 8 approximately the thickness of the palm, but is integrally connected to the refrigerating compartment 7. As shown in FIG. 2, the open cross section of the freezing compartment 6 is retracted and offset from the open front of the inner container 5 to the rear. The gap 8 between the freezer compartment and the refrigerating compartment 7 extends only approximately 2/3 to 3/4 or more of the depth of the inner container 5. In this shape of the inner container 5, the freezer compartment 6 is connected to the refrigerating compartment 7 in a flexurally rigid manner, ie a gap 8 which is opened for installation of the evaporator. It should not be bent or kinked away. However, the gap 8 has a thickness sufficient to accommodate the winding of the evaporator.

As shown in FIG. 2, a wound box evaporator 9 is positioned in the freezer compartment 6 in a precisely fitted and matched form, which is freely angled by the winding 10 of the evaporator 9. multilaterally) surrounded. In the illustrated embodiment, only the back wall of the evaporator cylinder is not covered by the wound evaporator 9. The evaporator 9 can cool the freezer compartment with high efficiency by enclosing the evaporator cylinder in various ways.

As shown in FIG. 2, the wound evaporator 9 comprises a plurality of winding coils which may comprise a bent aluminum pipe. Preferably, metal plates, not shown, on which the windings 10 of the evaporator 9 are arranged are located between the freezer compartment 6 and the windings 10 of the evaporator 9. The metal plates are attached to the wall surface of the freezer compartment as double-sided adhesive tape. The wound 10 of the evaporator 9 can likewise be attached to the metal plates in a known manner. The metal plate may be arranged on four sides of each of the freezing chambers 6 surrounded by the evaporator 9.

The evaporator 9 may be a so-called four-star evaporator having a wound evaporator box system installed in the freezer compartment 6 of the penetrating inner container 5 of the one-door refrigerator unit having a freezer compartment. Preferably, the arrangement does not require separating the freezer compartment from the inner container. The through-type container has no joint line between the freezing compartment 6 and the refrigerating compartment 7 and there is no bent end, so that no waste collecting end occurs, thus improving appearance. Moreover, this advantage eliminates the complexity and / or expensive sealing involved in carrying out the installation of the evaporator or evaporator box system into the inner container 5. Moreover, the evaporator 9 becomes inconspicuous in the interior space of the apparatus. In summary, a high efficiency evaporator is provided using inexpensive elements without the user's disadvantage.
