As shown in Figure 11 and Figure 12, carry in wind path 172(Fig. 5 the zone by dotted line), by right Embedded Division 191, left Embedded Division 192, wind path face portion 196 and wind path back part 103, formed.In addition, low temperature is with the zone surrounded by chain-dotted line in wind path 195(Fig. 5), form wind path 195 for low temperature by the part of right Embedded Division 191, side pipe side protuberance 194, the part of wind path face portion 196, a part and the top pipe side protuberance 193 of wind path back part 103.; interior case 11a and conduit component 182; by being that to be embedded into a pair of slot part be right slot part 101 and left slot part 102 for right Embedded Division 191 and left Embedded Division 192 by a pair of Embedded Division; formation is as the conveying wind path 172 of the 3rd wind path; and by making wind path back part 103 and top pipe side protuberance 193 and side pipe side protuberance 194 butts as the pipe side protuberance, at the wind path 195 for low temperature of carrying the interior formation of wind path 172 as the first wind path.
In the freezer 21,121 of present embodiment 3, be embedded into by right Embedded Division 191 and the left Embedded Division 192 that will be formed at conduit component 182 right slot part 101 and the left slot part 102 that is formed at interior case 11a, form and carry wind path 172, therefore at least 2 faces of the side of slot part 101,102 and Embedded Division 191,192 sides (, slot part and Embedded Division are along 2 sides of the direction embedded) be close to, can guarantee thus the sealing between the back side of conduit component 182 and interior case 11a.Therefore, can reduce from carrying the leakage of wind path 172 interior cold air to refrigerating chamber 22, can with blow-off outlet 187, cold air be blown out with blow-off outlet 186 and side refrigeration from the front refrigeration that is arranged at appropriate location reliably.
In addition, low temperature with wind path 195 by top pipe side protuberance 193 and the right slot part 101 of side pipe side protuberance 194 and interior case 11a and wind path back part 103 butts between left slot part 102 are formed.Therefore, low temperature is guaranteed sealing with wind path 195 by a face, because Embedded Division is embedded into the structure of slot part, cooling gas leakage likely occurs.But, because the inboard carrying wind path 172 arranges wind path 195 for low temperature, even therefore hypothesis cold air leaks with wind path 195 from low temperature, cold air also leaks into to be carried in wind path 172, can prevent that cold air from directly leaking into refrigerating chamber 22 from low temperature with wind path 195.
Flow through the cold air of carrying wind path 172, lower than 1 ℃～5 ℃ temperature for refrigerated compartment 22.That is, the cold air in wind path 195 and the temperature difference of carrying the cold air in wind path 172 for low temperature, be less than the temperature difference of low temperature with the cold air in the cold air in wind path 195 and refrigerating chamber 22.
Therefore, the freezer of present embodiment 3, by wind path 172 is interior arranges wind path 195 low temperature for carrying, compare with the freezer 21,121 of embodiment 1 and embodiment 2, can prevent the cooling effectiveness reduction.
And, in the freezer of present embodiment 3, low temperature is easy with the change of the structure of wind path 195.For example, as shown in figure 13, if adopt the structure that from conduit component 182, does not form top pipe side protuberance 193 and side pipe side protuberance 194, can not change becoming structurally of interior case 11a and not form the structure of low temperature with wind path 195.Thus, can be manufactured on by common structure the interior case 11a of the freezer that there is freezer room 63 in refrigerating chamber 22 and not there is the interior case 11a of the freezer of freezer room 63 in refrigerating chamber 22.Thus, do not need to prepare the mould of multiple interior case 11a shaping use for freezer in specie not, can reduce the manufacturing cost of freezer.
In addition, in order to abolish the pipe side protuberances such as top pipe side protuberance 193, side pipe side protuberance 194, as long as the conduit component 182 excision pipe side protuberances from being provided with the pipe side protuberance.In addition, also can again make in addition the conduit component that there is no the pipe side protuberance.In the latter case, conduit component 182 is less than interior case 11a, be used to form the mould of conduit component 182 also than the mold small that is used to form interior case 11a, the mould that the mould of therefore making conduit component 182 shaping use is used than case 11a moulding in making, can cut down the mould expense.Therefore, can reduce the manufacturing cost of the freezer while manufacturing the pipelines parts.
And, side pipe side protuberance 194 is arranged on the position of comparing Embedded Division 191 sides of more keeping right with left Embedded Division 192 sides, low temperature consists of side pipe side protuberance 194 with a sidewall of wind path 195, another sidewall is not other side pipeline protuberance to be set be exclusively used in wind path 195 for low temperature, but shares the right Embedded Division 191 as the sidewall of carrying wind path 172.
Like this, 1 side pipe side protuberance 194 only is set and uses the wall section of the side side of wind path 195 special uses as low temperature, form thus wind path 195 for low temperature, therefore can reduce hardly the sectional area of carrying wind path 172 and low temperature to use wind path 195.Thus, can not make to carry wind path 172 and the low temperature wind path resistance increment of wind path 195, can prevent that cooling effectiveness from reducing.
In addition, carry in wind path 172 and be provided with wind path 195 for low temperature, therefore with carrying wind path 172, with the situation that low temperature arranges separately respectively with wind path 195, compare, even reduce the thickness of the wall of wind path, also can make to flow through the uniformity of temperature profile of low temperature with the cold air of wind path 195, can prevent that the Temperature Distribution in freezer room 63 from becoming inhomogeneous.
And, with along with slot part 101,102 and Embedded Division 191,192 roughly the mode of the direction of quadrature arrange above the roughly the same height of pipe side protuberance 193, be formed with for fixedly top jut 105 and the below jut 106 of thermal wall 62.And, be provided with thermal wall 62 between jut 105 and below jut 106 up.Thus, can limit top pipe side protuberances 193 movement (for example, forming the forwards deflection of conduit component 82 of top pipe side protuberance 193) forwards by thermal wall 62.Therefore, can prevent from producing gap between pipe side protuberance 193 and interior case 11a up, can further reduce cooling gas leakage.

Figure 14 is the sectional view of conveying wind path of the freezer of embodiment 4.In present embodiment 4, only the aspect different from embodiment 1～3 described, for same structure, action and effect, description thereof is omitted.
In present embodiment 4, the back side at interior case 11a, with above pipe side protuberance 193 and side pipe side protuberance 194 relative position respectively, as the back side from interior case 11a inwardly side protruding the inner box side protuberance that forms, be respectively arranged with top inner box side protuberance (not shown), side inner box side protuberance 107.That is,, as top inner box side protuberance and the side inner box side protuberance 107 of the inner box side protuberance of above-mentioned wind path back part, be formed on the position relative with side pipe side protuberance 194 with top pipe side protuberance 193 as the pipe side protuberance.
By inner box side protuberance and side inner box side protuberance 107 above arranging at interior case 11a, the impact of the warpage in the time of can reducing the shaping at the back side of interior case 11a, therefore the sealing between interior case 11a and conduit component 182 can be improved, the cooling gas leakage with wind path 195 from low temperature can be further reduced.
In addition, top inner box side protuberance and side inner box side protuberance 107, be arranged to height (length of fore-and-aft direction) lower than top pipe side protuberance 193 and side pipe side protuberance 194.Thus, as shown in figure 15, pipe side protuberance 193, side pipe side protuberance 194 above discarding from conduit component 182, and discarded low temperature is with in the situation of wind path 195, top inner box side protuberance, side inner box side protuberance 107 also can reduce the sectional area of carrying wind path 172 hardly, therefore substantially can not increase the wind path resistance of carrying wind path 172, can do one's utmost to prevent that cooling effectiveness from reducing.
(embodiment 5)
Figure 16 is the front elevation (figure seen from the face side of freezer 21) of structure of rear side of the interior case 11a of the freezer for embodiments of the present invention 5 are described, and Figure 17 is the sectional view of carrying wind path.In the present embodiment, only the aspect different from embodiment 1～4 described, for same structure, action and effect, description thereof is omitted.
In present embodiment 5, with the inscape of a pair of slot part 101, the 102 performance same purposes of embodiment 3,4, by a plurality of protuberances, be that right outside side protuberance 201, Right Inboard protuberance 202, left-external side protuberance 203 and left inside side protuberance 204 form.
Thus, with the situation that is provided with the slot part of concavity at interior case 11a, compare, the seal length in the cross section of the part of sealing is elongated, therefore can reduce cooling gas leakage.In addition, due to the part that the thickness that does not make insulator 11c reduces, therefore can improve the thermal insulation of refrigerating chamber 22, can prevent that cooling effectiveness from reducing.
In addition, the height of right outside side protuberance 201, Right Inboard protuberance 202, left-external side protuberance 203 and left inside side protuberance 204, the height that is compared to the top inner box side protuberance of inner box side protuberance and side inner box side protuberance 107 is low.
Like this, the impact of the warpage in the time of can reducing the back-welding shape of interior case 11a, therefore can improve the sealing between interior case 11a and conduit component 182, can further reduce the cooling gas leakage from low temperature use wind path 195.In addition, simultaneously, as shown in figure 18, pipe side protuberance 193 and side pipe side protuberance 194 above discarding from conduit component 182, and discarded low temperature is with in the situation of wind path 195, top inner box side protuberance and side inner box side protuberance 107 also can reduce the sectional area of carrying wind path 172 hardly, therefore substantially can not increase the wind path resistance of carrying wind path 172.Therefore, can do one's utmost to prevent that cooling effectiveness from reducing.
In addition, as shown in figure 16, the length of low temperature by the short transverse of the freezer 21 of the Right Inboard protuberance 202 of a side of wind path 195 is set, is arranged to shorter than the length of right outside side protuberance 201.In addition, the lower end of Right Inboard protuberance 202, be arranged to and top pipe side protuberance 193 butts (the B zone surrounded by short dash line in Figure 10).
Thus, low temperature consists of side pipe side protuberance 194 with a sidewall of wind path 195, and another sidewall can not arrange other side pipeline protuberance, and consists of the right outside side protuberance 201 of the sidewall as carrying wind path 172.
Like this, by only being set, 1 side pipe side protuberance 194 uses the wall section of the side of wind path 195 special uses as low temperature, and not with Right Inboard protuberance 202 but with right outside side protuberance 201 formation wind path 195 for low temperature, can reduce hardly the sectional area of low temperature with wind path 195, therefore can basically not increase the wind path resistance of low temperature with wind path 195.Therefore, can do one's utmost to prevent that cooling effectiveness from reducing.
In addition, the height of the depth direction of the freezer 21,121 of Right Inboard protuberance 202 and left inside side protuberance 204 (height apart from wind path face portion 196 of conduit component 182), be arranged to higher than the height of right outside side protuberance 201 and left-external side protuberance 203.
Like this, the height of the protuberance by making a side more approaching with wind path 195 with carrying wind path 172, low temperature uprises, can further reduce from carry wind path 172, low temperature with wind path 195 cooling gas leakage.In addition, the lower end of Right Inboard protuberance 202 with above the butt position of pipe side protuberance 193 (in Figure 10, the B zone surrounded by short dash line), can make the seal length of depth direction of freezer 21,121 elongated, the cooling gas leakage between the conveying wind path 172 that therefore can further reduce this position and low temperature use wind path 195.
In addition, in the above embodiment, example as change low temperature by the structure of wind path 195, the situation of removing the pipe side protuberance is illustrated, but position, the size that is arranged on the low temperature use wind path 195 of carrying in wind path 172 changed in the position, size etc. that also can the pipe side protuberance be set by change.Now, also can coordinate the position that blows out hole 185 and front low temperature use blow-off outlet 88, size etc. for the low temperature of change front.
Above, the freezer of embodiments of the present invention 1～5 is illustrated, but the present invention is not limited to this embodiment 1～5.
