Then, deodorizing parts are described.Deodorizing parts 40 are arranged on cold air refluxing opening 33 places of refrigerating chamber back panel 30, and the cold airflow spraying to refrigerating chamber 2 from cooler chamber is to cold air return port 33, by deodorizing parts 40.

At this, the layout of deodorizing parts 40 as shown in Figure 5, that is, is arranged to not block the whole width ranges of cold air path left and right directions.This be because, when produce condensate water on deodorizing parts 40, these condensate water will be frozen, like this, because cold air is not by deodorizing parts 40, cooling capacity just can not reduce.In addition, indicated from the sectional view of the back panel 30 shown in Fig. 6, the structure of deodorizing parts 40 is made whole width of the depth direction that does not stop up cold air path.This is also according to reason same as described above.

Then,, with reference to Fig. 6, Fig. 7, describe the arrangement details of deodorizing parts 40 in detail.Fig. 6 is the sectional view of back panel 30, and its left side is refrigerating chamber side, and its right side is refrigerator rear side.Deodorizing parts 40, have cold air to flow along the direction of the hollow arrow shown in figure around, and the surface that is provided with the cold air path of deodorizing parts 40 is bending with respect to the angle that arranges of deodorizing parts 40.Therefore, can judge from Fig. 6, the inflow face of deodorizing parts 40 and the entrance of cold air path, be not in rectangular position., the inflow face of deodorizing parts 40 is positioned at along the direction of the cold airflow entering from cold air path entrance.

Conventionally, deodorizing parts are arranged to the flow direction facing to cold air, and cold air flows in deodorizing parts with laminar condition.

, in order to increase the internal capacity of refrigerator, cold air path is done thinly as shown in FIG. 6 and be complicated, large deodorizing parts can not be set.In addition, in the cold air path shown in Fig. 6, cold air not with laminar condition by deodorizing parts.

Therefore, present embodiment is made the structure that obtains high odor removal efficient with little deodorizing parts.With Fig. 8, Fig. 9, this structure is described below.

Deodorizing parts 40 are sneaked into blowing agent in polyurethane, after making its foaming, have open-celled structure (removing the hole 40a after adventitia) through specially treated, are the little structure of flowing resistance.There is the structure of hole 40a also referred to as being communicated with bubble structure, it is the structure of having aperture 40a in a kind of bubble one by one of matrix material 40b forming at polyurethane in vain, due to the high voidage that polyurethane foam has ternary structural and obtains by removing film, thereby can obtain good deodoriging properties with the very low pressure loss.

General foamed plastics leaves film between Kong Yukong, but can remove these films completely by special physical treatment.Therefore,, shown in the flow pattern figure of cold air as shown in Figure 9, deodorizing parts are the filtration device structures that are made up of the hole being communicated with.

In honeycomb in the past, the hole that cold air passed through of the cold air path in filter is open along cold air air-flow abreast.On the other hand, as shown in Figure 8, the hole 40a of the deodorizing parts 40 of present embodiment is the network-like opening that is three-dimensional.In addition, deodorizing parts be with the above unlimited state arrangement of three faces on cold air runner.Therefore, the cold air air-flow that flows through deodorizing parts 40 inside be turbulent flow, the inflow direction of cold air is different from Way out, thus cold air can by from cube towards the different face of consistent face.

; if polygonal deodorizing parts are arranged in a part for runner section; these deodorizing parts are made to the structure with one group of ventilation face and other ventilation face; just become turbulent flow by the cold air of deodorizing parts 40 inside; the inflow direction of cold air is different from Way out, thereby has improved the contacting efficiency of cold air.

In addition, if deodorizing parts make cold air flow into have on surface by dull and stereotyped alternately laminated with corrugated plating after the structure of the section of cut-out sideling, the inflow direction of cold air is different from Way out, cold air by deodorizing parts 40 inside has just formed turbulent flow, thereby has improved odor removal efficient.

The performance of deodorizing parts then, is described with reference to Figure 10.Label 100 represents open-celled structure deodorizing parts, and label 101 represents honeycomb deodorizing parts in the past.

Experiment shown in Figure 10 is in the refrigerator of common operating condition (the cooling operating condition of refrigerating chamber), inject that (it is the main component of refrigerator foul smell composition as the methyl mercaptan of calibrating gas, the corrupt compositions of a kind of vegetables), and along with the propelling of time, measure the concentration of methyl mercaptan in refrigerator, thereby determine the degree of concentration decline.

In addition, because the deodorizing parts 100 of open-celled structure are the same with the apparent volume of the deodorizing parts 101 of honeycomb in the past, so the content of the active ingredient of performance deodoriging properties is also identical with formula.

As seen from Figure 10, the deodorizing capability of this open-celled structure deodorizing parts 100 is higher than the deodorizing capability of honeycomb deodorizing parts 101 in the past.Open-celled structure deodorizing parts 100 and honeycomb deodorizing parts 101, its apparent volume is all the same with content and the formula of the active ingredient of performance deodoriging properties, their difference is to allow the mode of offering in the hole that cold air passes through.; linearly with Way in and Way out in the past; compare by the alveolate texture deodorizing parts 101 of deodorizing components interior with laminar condition; the inflow direction of cold air is different from Way out; cold air can by from relative to each other the one group ventilation face that ventilation face is different of three-dimensional shape, can allow cold air can bring into play higher deodorizing capability with turbulent condition by the open-celled structure deodorizing parts 100 of deodorizing components interior.

Therefore, according to present embodiment, cold air is easy to circulation, and can improve the contacting efficiency of odor removal filter surface and foul smell composition, thereby can carry out fully deodorizing to the foul smell in refrigerator.
