The specific embodiment
[embodiment 1]
In Fig. 1～Fig. 3 of the freezing-cooling storeroom that represents embodiments of the present invention 1, Reference numeral 1 is the freezer main body, Reference numeral 2 is the heat insulating boxes that consist of the freezer main body 1 of front openings, by outer container 3, interior case 4 and be filled in outer container 3 and interior case 4 between heat insulation material 5 consist of.
Epimere in freezer main body 1 arranges refrigerating chamber 6, under refrigerating chamber 6, across partition member 6a, is set up in parallel ice-making compartment 7 and can temperature controls to switching chamber 8 below 0 ℃.Reference numeral 7a is the partition member of separating ice-making compartment 7 and switching chamber 8 and refrigerating chamber 9 described later.In addition, be provided with vegetable compartment 10 at hypomere, on vegetable compartment 10, be provided with refrigerating chamber 9 across partition member 10a.In addition, Reference numeral 9a is the refrigerating chamber lower house that is arranged at the bottom of refrigerating chamber 9, and Reference numeral 9b is the refrigerating chamber upper shell that is arranged at the top of refrigerating chamber 9.
Rear side in above-mentioned each chamber is provided with rear wall 17, from the rear side of partition member 7a until the rear side of refrigerating chamber 9, form cooler chamber 20 between the interior case 4 of rear wall 17 and heat insulating box 2, in cooler chamber 20, the cooler 21 that consists of freeze cycle roughly arranges vertically.In addition, rear wall 17 is in the rear side of refrigerating chamber upper shell 9b, towards rear side along oblique upper branch, the top of inaccessible cooler chamber 20, side is formed with large spatial portion (below, the rear wall of this branch is called the rear wall 17a of branch) in front.
In addition, by pressure fan 23 is set obliquely, between the interior case 4 of the blade of pressure fan 23 and heat insulating box 2 stenosis little, blade might touch interior case.Therefore, only make interior case 4 depressions with the discontiguous degree of blade, be provided with the vertical and smooth recess 4a in bottom surface.
Even recess 4a is set in this wise, because the amount of recess of recess 4a is minimum, so the loading (thickness) that is filled in the heat insulation material 5 between outer container 3 and the interior case 4 does not almost change, in addition, can not impact the shape of the vacuum insulation material of landfill in heat insulation material 5, thickness etc. yet.In addition, do not have possibility to touch in the situation of interior case 4 at the blade of pressure fan 23, need not to arrange recess 4a.
In the freezer that consists of as described above, be condensed device (not shown) condensation of the cold-producing medium that has been compressed by the compressor 16 that consists of freeze cycle, the cold-producing medium that has been condensed is by throttling arrangement (not shown) decompression, and delivers to cooler 21, evaporation in cooler 21.Heat-absorbing action when utilizing this evaporation, the periphery of cooler 21 (cooler chamber 21) is cooled.
The cold air that is generated by cooler 21 imports the 1st wind path 22 by pressure fan 23, from the 1st wind path 22 via bottom blow-off outlet 25 and top blow-off outlet 26, supply with to refrigerating chamber 9, to be incorporated in food in refrigerating chamber lower house 9a and the refrigerating chamber upper shell 9b be controlled to be can long preservation temperature (for example ,-18 ℃).
On the other hand, be sent to the cold air of the 2nd wind path 22a from the 1st wind path 22 via volume damper 24, carried to refrigerating chamber 6, ice-making compartment 7, switching chamber 8 and vegetable compartment 10, utilize volume damper 24 to regulate air quantity, above-mentioned each chamber is controlled to be suitable temperature.
According to the present embodiment that consists of as described above, as required, position at the interior case 4 corresponding with the blade of the pressure fan 23 that arranges obliquely, be provided with a little depression, the vertical and smooth recess 4a in bottom surface, therefore, hardly the loading (thickness) of the heat insulation material 5 between outer container 3 and the interior case 4 impacted, in addition, the shape of the vacuum insulation material of landfill in heat insulation material 5, thickness do not change yet, and energy saving is realized on the heat-proof quality ground that therefore can can't harm the back side of refrigerating chamber 9.
In addition, in order to guarantee sufficient space blowing out side, pressure fan 23 is set obliquely, fully guaranteed the highest space that blows out side of the pressure loss (the 1st wind path), so can be via the 1st wind path 22 and the 2nd wind path 22a, to the cool-air feed reliably such as refrigerating chamber 9, refrigerating chamber 6, thus, can wind path efficient not improved cooling performance with impacting.
[embodiment 2]
Fig. 4 is the key diagram of major part of the freezing-cooling storeroom of embodiments of the present invention 2.In addition, to part mark with it the identical Reference numeral identical with embodiment 1.
In the present embodiment, tilt angle theta under take the radius of the blade face of pressure fan 23 as d, take the aperture area of the top blow-off outlet 26 of the refrigerating chamber upper shell 9b transporting cold-air from the 1st wind path 22 to refrigerating chamber 9 as the situation of A, pressure fan 23 is set as
1.1×A＜dsinθ＜0.9×A。
By setting as described above the tilt angle theta of pressure fan 23, can prevent that the cooling effectiveness that causes from the heat leak of the switching chamber 8 on the top of being located at refrigerating chamber 9 from reducing, and can improve the cooling effectiveness of refrigerating chamber upper shell 9b.
