Embodiment 1

The summary structure of the refrigerator that first embodiment relates at first, is described with reference to Fig. 1.Here, Fig. 1 is the summary structure chart of the refrigerator that relates to of first embodiment.

In Fig. 1, by the overall expression of mark 1 be by means of thermal baffle 11 with cutting apart up and down in the case, making the upper strata is refrigerating chamber 100, making lower floor is the refrigerator of being called as of refrigerating chamber 200 putting top formula refrigerator.Refrigerating chamber 100 and refrigerating chamber 200 its open front can be installed shutter door 101, shutter door 201 respectively at this open section with opening and closing.

Refrigerating chamber 100 is storerooms of setting with the temperature band of-18 ℃ of front and back Celsius, is cut apart up and down by means of interval shelf (bodyguard is cut canopy) 110.And, in this refrigerating chamber 100, can preserve frozen food and utilize ice making tray 111 to come ice making, preserve the Xingqi of going forward side by side.On the other hand; Refrigerating chamber 200 is with from-2 ℃ of storerooms of setting to temperature band Celsius 6 ℃ Celsius; A plurality of by means of two receivers (first receiver 270 and second receiver 280) and interval shelf 290 with being divided in the case, can divide the classification of careful (the thin か of wooden order) and take in.

And one of the refrigerator 1 that this embodiment relates to is characterised in that greatly, can replace a receiver (second receiver 280) in the upper and lower.

That is, this two-door refrigerator is simple in structure and ability is cheap makes, therefore a lot of regional popularizing in the world.And its refrigerating chamber is typically provided with first receiver (vegetables receiver) of mainly taking in greengrocery and mainly takes in second receiver (ice-cold box) of ice-cold food (チ Le De food) and meat.Under the situation of putting top formula refrigerator, refrigerating chamber is arranged on top, so the storage temperature band can be arranged on the top of refrigerating chamber with coming in and going out for-2 ℃ to 3 ℃ second receiver.On the other hand, storage temperature be 4 ℃ to 6 ℃ first receiver be arranged on from refrigerating chamber away from the foot of refrigerating chamber.And existing refrigerating chamber is cut apart up and down between its two by a plurality of intervals shelf, can take in numerous food.

But; The specification of this refrigerator serviceability for having the user that the chilled food that comprises ice-cold food and greengrocery is various cooking culture is good; But; For eating the user that ice-cold food is perhaps eaten the area of greengrocery hardly or had the mixed area that occupies of user of these cooking cultures hardly, there is the bad problem of serviceability.Especially; If icing then very awkward vegetables and chilled food etc. can't be accommodated in the second low receiving room of temperature band; Therefore for the user of the ice-cold food of eating meat and cheese etc. hardly, the accommodation space of this second receiver becomes the poor especially space of serviceability.

, if the refrigerator of multiple other specifications is provided with can satisfying these demands, then effective to the user.But, aspect simple in structure and low price, having in this refrigerator of big advantage, the refrigerator structure that satisfies this type of demand complicates, and cost up, so its present situation is to satisfy these demands.

So invention of the present invention artificially reduces the storage temperature band, conceive as follows: be conceived to second receiver 280, this second receiver 280 is moved in refrigerating chamber 200 near refrigerating chamber 100 configurations.

Promptly; Inventor of the present invention has conceived following refrigerator: when being installed in the upper strata of refrigerating chamber 200; Can become-2 ℃ to 3 ℃ the storage temperature band that mainly is suitable for most taking in ice-cold food; And, when being adjacent to beautiful installation on top with first receiver 270 of the lower floor of refrigerating chamber 200, can be as the refrigerator of two-layer vegetable compartment.And in this design, the simple structure that the enough guide rail mechanisms 300 of pulling out second receiver 280 of ability are located at the last lower wall surface of refrigerating chamber 200 realizes.

In addition, another of the refrigerator 1 that relates to of this embodiment is characterised in that greatly: the track of pulling out that changes second receiver 280 in the upper and lower.Promptly; In this refrigerator 1; On the upper strata rail 310 of being located at refrigerating chamber 200 the superiors, be provided with the leaning device of pulling out second receiver, 280 front portions downwards obliquely, on the lower layer track 350 of being located at refrigerating chamber 200 lower floors, be provided with the horizontal mechanism that level is pulled out second receiver 280.

Usually, during the receiver that above higher position is provided with, opens wide, exist the place ahead wall of receiver to become obstacle, be difficult to see inside, and be difficult to the problem taking out and put into.In addition, under the situation of pulling out box that supports by the guide rail mechanism of being located at the internal face of both sides in the case, come off the problem that existence can not forwards be pulled out significantly in order to prevent to pull out.Especially, in the refrigerator 1 of putting top formula refrigerator that this embodiment relates to, the upper end of second receiver is covered by thermal baffle 11, and in addition, because the existence of door pocket 220, second receiver 200 is in the configuration of the inboard of refrigerating chamber 200.

Therefore, existing second receiver, the place ahead of second receiver that opens wide with the top forwardly is provided with the open-close lid that interlock ground opens and closes of pulling out with second receiver, solves the problems referred to above.

But if in " structure that second receiver 280 is moved " than big characteristic as this embodiment, adopt the existing structure of above-mentioned open-close lid in refrigerating chamber 200, then structure becomes complicated, and becomes the major reason that cost significantly rises.

So inventor of the present invention is being configured in second receiver 280 under the situation of high position, be provided with and make anterior leaning device of pulling out obliquely downwards, second receiver 280 is being configured under the situation of lower position the horizontal mechanism that the level of setting is pulled out.

In addition; Another big characteristic of the refrigerator 1 that this embodiment relates to is; The inside plates 230 in the refrigerating chamber 200 are formed flatly substantially, and the formed refrigerating chamber of the inside side that is formed on this inside plate 230 is with cold air path 20, disposes cold air switching air door 30 at this refrigerating chamber in cold air path 20.
