Preferably, the path in point next door makes evaporator room be connected with the 2nd storage chamber, can be drawn in evaporator room from the 2nd storage chamber by air.

One passage being connected on described path on the side of the 2nd storage chamber preferably has an inlet mouth in the region deviating from point next door of the 2nd storage chamber, to guarantee the air flow driven by ventilator also completely through the 2nd storage chamber.

Preferably, the storage chamber separated by spaced walls and evaporator room is configured to freezing compartment, is furnished with the 2nd storage chamber being configured to refrigerate lattice above this freezing compartment. Arrange (wherein, vaporizer is arranged adjacent with freezing compartment) by this kind, be stored in vaporizer cold can in compressor rest time and/or ventilator rest time heat power ground and then be particularly advantageously used to freezing compartment in energy.

Other features and advantages of the present invention are drawn by the description of following examples with reference to accompanying drawing. Accompanying drawing illustrates:

Fig. 1 illustrates the sectional view of the refrigerating appliance of the first configuration according to the present invention,

Fig. 2 illustrates the sectional view according to the 2nd configuration; With

Fig. 3 illustrates the sectional view of the 3rd configuration according to the present invention.

Fig. 1 illustrates the combination refrigerating appliance with two storage chambers, i.e. common refrigeration lattice 1 and a freezing compartment 2, embeds heat insulation point next door 3 between described storage chamber. The wall 5 parallel by the back wall 4 of a vertical body with refrigerating appliance divides out an evaporator room 6 from freezing compartment 2, is provided with a vaporizer in this evaporator room, is plate evaporator 7 here. Wall 5 has a circular open 8 in lower region thereof, in the lower section of plate evaporator 7. Being provided with a ventilator motor 9 in back wall 4 at this opening rear, this ventilator motor drives one to be arranged in the impeller 11 before wall 5 by the axle 10 intersected with opening 8.

Impeller 11 has the substrate 12 of plane substantially, and multiple blade 13 is outstanding to the direction of back wall 4 from the edge of this substrate. Described blade is substantially relative to the rotation 28 radially orientation of impeller 11, thus the air caught by blade 13 that rotates of impeller 11 is driven away from described blade transverse to rotation 28 ground and is produced the flowing parallel with wall 5 like this distributing chamber 15, this distributing chamber in side by wall 5 gauge and in another side by the dorsal part gauge opposite with wall 5 pulling out box 14. Therefore, be gathered in even air in whole distributing chamber 15 and flow out time be distributed in draw from distributing chamber 15 from all flowing-paths, that is, two all spaces 16 pulled out between pull-out box 14 that is between pull-out box 14 between boxes 14, above and point next door 3 or bottom and the bottom of freezing compartment 2 are all supplied with the freezing air from evaporator room 6. Freezing compartment 2 does not exist and the region of the de-coupling of the circulation of air, and the temperature of different pull-out boxes 14 is under any circumstance mutually not different significantly.

, after described space 16, the path 17 of described air through the common door 18 and the front rib limit in point next door 3 of described two lattice 1,2 arrives in common refrigeration lattice 1.

The passage 19 out led back to evaporator room 6 from common refrigeration lattice 1 by extending to wall 20 gauge near the top of common refrigeration lattice 1 along back wall 4 from point next door 3. Therefore, in order to arrive the inlet mouth 21 of passage 20, described air must rise on the whole height of common refrigeration lattice 1, thus also realize uniform temperature distribution here.

Identical with the configuration situation of Fig. 1, refrigerating appliance is divided into common refrigeration lattice 1, freezing compartment 2 and evaporator room 6 by wall 3,5 in inside; In addition having the spaced walls 22 substantially parallel, vertical with wall 5, distributing chamber 15 and freezing compartment 2 are separated by this spaced walls. Path 23 in spaced walls 22 points to space 16, to ensure that air is unhinderedly transitioned in space 16.

As when Fig. 1, the radial ventilation device with motor 9 and impeller 11 is arranged in opening 8 place of wall 5, so that air is extracted out from evaporator room 6 and be discharged in distributing chamber 15 transverse to rotation 28 ground of this ventilator. But, in the configuration situation of Fig. 2, ventilator is arranged in distributing chamber 15 completely, and the motor 9 of ventilator is fixed in spaced walls 22. Ventilator, spaced walls 22 and connected wall 5 form a structural unit, this structural unit can be arranged in refrigerating appliance as a whole and also can be disassembled as a whole again, with box lunch for cleaning and safeguard the needs of object, such as make the water of condensation Receiving bin on the footing of vaporizer 7 and back wall expose to remove from during settling in the exhaust channel that water of condensation receiver 24 leads to environment. Spaced walls 22 covers the back wall 4 below point next door 3 completely and forms face easy to clean, smooth, and this face extends to another sidewall from a sidewall of refrigerating appliance body in the two directions and in the vertical direction extends from point next door 3 until the top 25 of machine chamber alcove 26.

In the configuration situation of Fig. 2, wall 5 has the recess 27 around opening 8, and to install impeller 11, and in the configuration situation of Fig. 3, wall 5 is smooth, and the substrate 12 of impeller 11 has the shape of bowl, and receiving in this bowl has the ventilator motor 9 being fixed on wall 20. Blade 13 deviates from the protruding outside of motor 9 from this bowl, and wherein, described blade is overlapping with motor 9 in the axial direction.

If the degree of depth of evaporator room 6 is little and there is not the space of the recess for wall 5, then this kind of structure formation of ventilator and wall 5 especially meets object. If as shown in Figure 3, plate evaporator 6 is replaced by the plate-type evaporator of a free suspension, especially a pressure welding formula vaporizer 27, then the degree of depth of evaporator room 6 especially can keep little. In order to produce the surface of the abundance of vaporizer 27, this vaporizer does not extend to the height of freezing compartment 2, and substantially extends on the whole height of common refrigeration lattice 2, and in there, vaporizer only needs to occupy slightly many spaces than the passage 19 of Fig. 2.
