As shown in Figure 3, the casing of refrigerator 1 is to reach the mode that overlaps to separate the space with respect to this outer container by outer container to be disposed at inboard interior box-shaped one-tenth, and constituted by the thermal insulation board (panel) that is filled with foaming carbamate (urethane), but by configuration vacuum insulation panel 30 in described space, can further improve thermal insulation.

By said structure, can make the thickness attenuation of thermal insulation board, guarantee that internal volume is roomy, and realize compactness (compact) change of outer volume.

And, in the thermal insulation board of the side of refrigerator 1, end face, front surface, round radiating tube 31, realizing the heat radiation of cooler, and prevent dewfall by making each several part keep low-temperature condition to contact with extraneous gas.

With reference to Fig. 4～Fig. 7, to the vegetable compartment 3 of refrigerator 1 more the storage space of being separated by heat insulation demarcation strip 41 40 of below describe.

By the profile of Fig. 4, Fig. 5 can be clear and definite be, this storage space 40 be by stride and the refrigerator of storage space 40 in set partition member 42 and be separated into the main refrigerating chamber 6 of refrigerating chamber 5 and its below between the left and right sides wall of front surface portion.

In the front surface inside of partition member 42, insert and to be connected with aforesaid radiating tube 43, by this partition member 42 is heated, make the surface contact extraneous gas of partition member 42 and dewfall is suppressed.

In last refrigerating chamber 5, can take in the last refrigerating chamber box 5A that front surface is equipped with refrigerating chamber door 5B with extracting out.In main refrigerating chamber 6, also be to take in the main refrigerating chamber box 6A that front surface is equipped with main refrigerating chamber door 6C with extracting out.

At the rear portion of this main refrigerating chamber box 6A, utilize otch and be formed with cold air inlet port 6Aa.At the upside of main refrigerating chamber box 6A, be provided with the secondary freeze box 6B that IQF is used slidably.

At the back of storage space 40, forming the air coolant tube 45 that is provided with refrigerated cooler 44, in the bottom of this air coolant tube 45, be formed with to the cold air sucting inlet 45A of main refrigerating chamber 6 openings.

Cold air in the refrigerator is directed into air coolant tube 45 from this cold air sucting inlet 45A, make its from bottom to top by refrigerated cooler 44 to be cooled to cryogenic temperature, and this cold air through cooling is blown out in the supreme refrigerating chamber 5 from the back, simultaneously, from the top of main refrigerating chamber 6 and the cold air blow-off outlet 46 of the upside that forms of pars intermedia position separately and the cold air blow-off outlet 47 of downside also blow out cold air, circulate in this way.

The forced circulation of this cold air is to be undertaken by the cooling fan on the top that is arranged on air coolant tube 45 (fan) (not shown).

The horizontal rear part of separating the partition member 42 of storage space 40 up and down becomes the little space 48 of separately going up refrigerating chamber 5 and main refrigerating chamber 6, cold air is being set in the position in this little space 48 is blowing out with conduit 49.

As the outside drawing write up of Fig. 6, Fig. 7, it is to be made of the 49A of air coolant tube portion and lid member 49B that this cold air blows out with conduit 49, the described air coolant tube 49A of portion is the rear portion wider width and the narrower flat cylindrical shell of anterior width, and described lid member 49B is formed on the side face of this conduit part 49A.

Blow out lower surface with the leading section of the 49A of air coolant tube portion of conduit 49 at this cold air, be formed with cold air blow-off outlet 50 in the mode of downwardly facing opening.And the open rearward end portion 51 of the 49A of air coolant tube portion also forms wideer width up and down when width broadens.This open rearward end portion 51 be embedded in air coolant tube 45 upsides cold air blow-off outlet 46 around and fix.

Shown in the dotted line among Fig. 6, in the inner space of the 49A of air coolant tube portion, be provided with reinforcement (rib) 52 along fore-and-aft direction.

This cold air blows out the 49A of air coolant tube portion with conduit 49 and constitutes the length in centre position that its cold air blow-off outlet 50 is positioned at the fore-and-aft direction in little space 48.

Thus, the Quilt with air conditioning that forwards blows out from the cold air blow-off outlet 46 of air coolant tube 45 blows out to cold air and blows out with in the 49A of air coolant tube portion of conduit 49, and then in the 49A of this air coolant tube portion, forwards advance, and blow out downwards from the cold air blow-off outlet 50 of its front end lower surface, the foodstuff that takes in the secondary freeze box 6B to the upside in the main refrigerating chamber 6 by the cold air that blows out carries out IQF.

Especially, owing to make cold air blow out the wider width of the rear end side of using conduit 49, therefore can import the cold air of air coolant tube 45 in large quantities, thus the cold air blow-off outlet 50 of the front end central authorities that cold air is concentrated on be positioned at air coolant tube 49A and blowing out to secondary freeze box 6B central portion.

And, describe as some chain lines among Fig. 4, by (set) aluminium sheet (aluminum plate) 54 is set in the bottom of secondary freeze box 6B, can make cold air diffuse to whole space in this pair freeze box 6B by aluminium sheet 54, thereby equably to carrying out freezing cooling in the secondary freeze box 6B.

For main freeze box 6A, utilize the cold air that blows out from the cold air blow-off outlet 47 of air coolant tube 45 by the centre position, back of storage space 40 to cool off.

Because the upper surface open portion of secondary freeze box 6B is covered by the lid member 49B that cold air blows out with conduit 49, therefore can mark off refrigerating chamber 5 and main refrigerating chamber 6, and can make secondary freeze box 6B become roughly closed state, thereby can carry out freezing cooling hastily.

And, to compare with main freeze box 6A, the storage capacity of secondary freeze box 6B is configured less, and is provided with aluminium sheet 54, therefore can carry out freezing cooling more hastily.And then owing to be in identical height with the lower surface of partition member 42, therefore can prevent when extracting out: freezing food is separated member 42 and catches on and be not drawn out of.

And the part of main freeze box 6A is also descended to cool off by the side of the cold air that last refrigerating chamber 55 is cooled off by secondary freeze box 6B, therefore can obtain cooling effectively.

So, be arranged in the little space 48 of horizontal rear part of partition member 42 by cold air being blown out with conduit 49, thereby have the following advantages: can blow out with conduit 49 for cold air is set originally being not used in the space of taking in food, can not reduce food storing space and cold air can be guided to the blowing out till the position of regulation, thereby can cool off main refrigerating chamber 6 equably.

And the fore-and-aft direction centre position at the storage space 40 in little space 48 makes cold air blow out from the cold air blow-off outlet 50 of the front end lower surface of the 49A of air coolant tube portion downwards, therefore can come whole and cool off equably from the top center of main refrigerating chamber 6.

And then, owing in secondary freeze box 6B, be provided with aluminium sheet 54, cold air is conducted heat.

And, because cold air can directly not blow to the partition member 42 that is positioned at 48 the place aheads, little space from behind, partition member 42 can not cooled off superfluously, and the dewfall of the partition member 42 that causes because of the extraneous gas with the table side contacts of partition member 42 is suppressed.

And under the situation of this 1st embodiment, radiating tube 43 is by the inside of partition member 42, and the ground that therefore can complement each other with the heat that radiating tube 43 brings positively prevents the dewfall on the partition member 42.

And then, make from the cold air of air coolant tube 45 cold air blow-off outlet 47 these two places by cold air blow-off outlet 50 and downside to blow out to main refrigerating chamber 6, therefore can be simultaneously parallel and effectively the part of the main freeze box 6A of the part of the secondary freeze box 6B in the main refrigerating chamber 6 and its below is cooled off.

Especially, can blow out by the cold air from cold air blow-off outlet 50 and hastily the secondary freeze box 6B of upside is carried out freezing cooling, and also cold air can be sent to the main freeze box 6A that is positioned at its below, thereby visual purpose is separately taken in food, is received in this pair freeze box 6B with the food that will desire IQF.

And owing to the mode that blows out cold air with the lower surface rear from secondary freeze box 6B towards the place ahead disposes cold air blow-off outlet 47, therefore also can cool off by the cold air that blows out from this cold air blow-off outlet 47 bottom surface of secondary freeze box 6B.

Therefore, can further improve the cooling performance that aluminium sheet 54 brings, and the rear of main freeze box 6A cut and be provided with cold air inlet port 6Aa, so that the cold air that blows out from cold air blow-off outlet 47 enters main freeze box 6A.

And, the rear end of cold air inlet port 6Aa is rearward extended, and along be positioned at air coolant tube 45 belows and suck refrigerator cold air cold air sucting inlet 45A the upper end and dispose cold air inlet port 6Aa, therefore can prevent " the Quilt with air conditioning cold air sucting inlet 45A from cold air blow-off outlet 47 directly sucks and ineffectually take a shortcut (shortcut) ", cold air can be effectively utilized the cooling in refrigerating chamber.

And, because cold air is set in the position in little space 48 to be blown out with conduit 49, and secondary freeze box 6B is covered by the lid member 49B that cold air blows out with conduit 49, therefore the cold air that blows out in making progress refrigerating chamber 5 from the back in little space 48 can not enter among the secondary freeze box 6B of main refrigerating chamber 6 upsides, but the both sides by secondary freeze box 6B are until downside and flow in the main freeze box 6A, thus also from around cool off the part of secondary freeze box 6B well.

(the 2nd embodiment)

Secondly, with reference to Fig. 8 to Figure 11 the 2nd embodiment is described.The difference of the 2nd embodiment and the 1st embodiment is, the extraction of ice making box, push operation are carried out smoothly, and the part different with the 1st embodiment described.

In ice-making compartment 4, side is provided with ice-making disc 401 thereon, is provided with the ice making box 4A that the ice of being made by ice-making disc 401 is stored at its downside.At this ice making box 4A ice-making compartment door 4B is installed.Below ice making box 4A, be provided with stiffener 402, can slide front and back to support ice making box 4A.The length of this stiffener 402 until the depth of ice-making compartment 4 midway till, be formed with opening 403 in its darker side.

And then, on lid member 49B, be formed with interconnecting part 49C at the position of the lower rear that is arranged in ice making box 4A (part of the left back of Figure 10), and, in the edge portion of the lid member 49B that is positioned at interconnecting part 49C front side, be formed with a plurality of more near interconnecting part 49C then more low tilted ribs 49D be used as guide portion.

And then, in the 49A of air coolant tube portion, in the part corresponding with the edge portion of aforesaid interconnecting part 49C side, be formed with more the more low rake 49E then near interconnecting part 49C, with as the protuberance more outstanding than other parts of conduit part 49A.

In addition, for interconnecting part 49C, under the situation of this 2nd embodiment, be to form by cold air being blown out cut with the part of the lid member 49B of conduit 49, but also can be in the appropriate section perforate of covering member 49B, with this hole as interconnecting part 49C.

And then, blow out with on the lid member 49B of conduit 49 at cold air, in the position of the lower rear of ice making box 4A interconnecting part 49C is set, and, be formed with more more low tilted ribs 49D and the rake 49E then near this interconnecting part 49C in the edge portion of interconnecting part 49C, play following effect thus.

To be stored in ice making box 4A automatically by the ice that ice-making disc 401 is made.When not forming interconnecting part 49C, tilted ribs 49D or rake 49E, in case the ice that is stored among this ice making box 4A is filled, then further make ice and the ice that drops from ice-making disc 401 overflows and is stuck in the gap between ice making box 4A and the ice-making compartment 4 from ice making box 4A sometimes.

And, roughly fill the following time of state of ice making box 4A being in ice, if the user extracts ice making box 4A out and takes out ice, subsequently ice making box 4A is pushed the operation in the ice-making compartment 4, then under this posture, the ice in the ice making box 4A also can overflow and be stuck in the gap between ice making box 4A and the ice-making compartment 4.

In such cases, can't extract, push the operation of ice making box 4A sometimes smoothly out.

Relative therewith, under the situation of this 2nd embodiment, owing to be formed with interconnecting part 49C, therefore in a single day the ice that is stored in this ice making box 4A is filled, even then further make ice and overflow from ice making box 4A from the ice that ice-making disc 401 drops, also can fall to the part of interconnecting part 49C by the opening 403 at stiffener 43 rears, and further arrive the following storeroom of its below by interconnecting part 49C, and can not be stuck in midway.

And, owing to tilted ribs 49D and rake 49E are that the edge portion that is adjacent to interconnecting part 49C forms, therefore drop to the sliding guidance that interconnecting part 49C ice on every side also can be subjected to these tilted ribs 49D and rake 49E, be directed to and fall into interconnecting part 49C, and by the following storeroom that interconnecting part 49C arrives its below, and can not be stuck in midway.

And, owing to will divide up and down as the main refrigerating chamber 6 of storeroom, at upside secondary freeze box 6B is set, at downside main freeze box 6A is set, and be formed with interconnecting part 49C in the mode that is communicated with the secondary freeze box 6B of upside, the ice that drops by interconnecting part 49C from ice-making compartment 40 is stayed in the secondary freeze box 6B of upside, had the advantage of easily removing the ice that drops.

Therefore, according to this 2nd embodiment, the ice of making ice and storage by ice-making compartment 4 can not be stuck in the gap between ice making box 4A and the ice-making compartment 4, can carry out extraction, the push operation of ice making box 4A all the time smoothly.

Therefore, the ice that can not cause ice making box 4A to be overflowed hinders and is stuck in ice-making compartment 4 midway, thereby causes ice-making compartment door 4B closing state fully.Therefore, ice can not melt under the situation that the user does not know yet, and helps energy-conservation yet.
