The specific embodiment
[embodiment 1]
In Fig. 1~Fig. 3 of the freezing-cooling storeroom that represents embodiment 1 of the present utility model, 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.
Reference numeral 11a, 11b are the opposite opened doors that opens and closes the front openings section of refrigerating chamber 6, but can be also 1 fan shutter door.Reference numeral 12 is the drawer type doors that open and close the front openings section of ice-making compartment 7, and Reference numeral 13 is the drawer type door of switching chamber 8 equally.Reference numeral 14 is the drawer type doors that open and close the front openings section of refrigerating chamber 9, and Reference numeral 15 is the drawer type door of vegetable compartment 10 equally.In addition, Reference numeral 16 is the compressors that consist of the freeze cycle of the rear side bottom be arranged at vegetable compartment 10.
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.
Reference numeral 22 is the 1st wind paths that are made of the large spatial portion between the front face side that is formed at the rear wall 17a of branch and rear wall 17, and Reference numeral 22a is formed between the interior case 4 of rear wall 17 and heat insulating box 2, the 2nd wind path that is communicated with the downstream of the 1st wind path 22.
Reference numeral 23 is to be equipped in the 1st wind path 22, is installed on obliquely the rear wall 17a of branch, and with the pressure fan of cooler chamber 20 sides as suction inlet, in an embodiment, this pressure fan 23 is 15 ° with respect to the tilt angle theta of vertical curve.In addition, cooler 21 is incorporated in the bottom projected area of pressure fan 23 of inclination.
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 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, in the situation that the blade of pressure fan 23 does not have possibility to touch interior case 4, need not to arrange recess 4a.
Reference numeral 24 is in the downstream of pressure fan 23, is located at the volume damper of the 2nd wind path 22a, is incorporated in the top projected area of pressure fan 23.
Reference numeral 25 is rear walls 17 of being located at refrigerating chamber 9, is communicated with the bottom blow-off outlet of the 1st wind path 22 and refrigerating chamber lower house 9a, and Reference numeral 26 is the rear wall 17 of being located at refrigerating chamber 9 equally, is communicated with the top blow-off outlet of the 1st wind path 22 and refrigerating chamber upper shell 9b.
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 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 via volume damper 24 from the 1st wind path 22, 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 depression, the vertical and smooth recess 4a in bottom surface a little, therefore, hardly the loading (thickness) of the heat insulation material 5 between outer container 3 and 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, therefore can can't harm refrigerating chamber 9 the back side heat-proof quality realize energy saving.
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 embodiment 2 of the present utility model.In addition, to part mark with it the identical Reference numeral identical with embodiment 1.
In the present embodiment, will be in the situation that take the radius of the blade face of pressure fan 23 as d, be set as 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 A, tilt angle theta pressure fan 23
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.
