It is positioned at the location directly below relation of foamed heat-insulating material inlet 33.It is to say, with send out
The entrance (one end) in the configured slot portion, position 36 that bubble heat-barrier material inlet 33 is opposed.Such as Figure 11
Shown in, expanded material injection head 34 is disposed of the vertical being positioned at foamed heat-insulating material inlet 33
The lower section in direction.And, foamed heat-insulating material 19 flows downward out along vertical, by gravity
Flowing.That is, the underface of foamed heat-insulating material inlet 33 is meant to be by gravity flowing
Position opposed with foamed heat-insulating material inlet 33 in the flow direction of foamed heat-insulating material 19.
It addition, as shown in Figure 14 and Figure 15, (decrement is to instigate to make the conquassation amount in groove portion 36
The distance of the Partial shrinkage in the groove portion 36 formed by compression) 39 area be expanded material note
Enter the sectional area more than 38 of the foamed heat-insulating material inlet 33 of 34, and, such as Figure 13 institute
Show, make the projected area that flow path cross sectional area 42 is foamed heat-insulating material inlet 33 in groove portion 36
On more than 50%.Thereby, it is possible to guarantee the area of the stream for foamed heat-insulating material 19 flowing,
It is thus possible to make the foamed heat-insulating material 19 being injected into from foamed heat-insulating material inlet 33 easily flow
Dynamic.
It follows that the formation pattern in groove portion 36 is illustrated based on Figure 16 and Figure 17.Figure
16 is the sketch of the example forming pattern representing groove portion 36.Figure 17 is to represent groove portion 36
The sketch of other example forming pattern.Arrow 40 is utilized at Figure 16 and Figure 17
Represent the flowing of polyurethane foam stock solution.
As it has been described above, polyurethane foam stock solution is from the multiple foaming heat insulation materials being arranged at backplate 20
Material inlet 33 (33a, 33b) injects.Polyurethane foam stock solution is noted when liquid
Enter, foam in the period in the space flowing through the refrigerator main body 30 comprising groove portion 36.Cause
This, also can exist in the overall space of refrigerator main body 30 and be difficult to filling-foam heat-barrier material
Part.Such as, for the formation pattern in the groove portion 36 shown in Figure 11, in groove portion 36 and groove portion
The mid portion of 36 is difficult to filling-foam heat-barrier material.
Therefore, it is possible not only on the extended line of expanded material injection head 34 be formed groove portion 36, also
Can be in the centre position of expanded material injection head 34 with expanded material injection head 34, and vertically
Direction forms groove portion 36 farthest away from the part of foamed heat-insulating material inlet 33.Such as, such as Figure 16
Shown in, it is also possible to the interposition towards expanded material injection head 34 with expanded material injection head 34
Put formation groove portion 36 inclined downward.Thus, even if in the position being difficult to filling-foam heat-barrier material
It also is able to filling-foam heat-barrier material such that it is able to eliminate the part being not filled by foamed heat-insulating material.
In addition it is also possible to by the formation pattern in the groove portion 36 shown in Figure 11 and the groove portion shown in Figure 16
The formation combinations of patterns of 36 is got up.It addition, the formation pattern in groove portion 36 and formation number are not
Be particularly limited, it is possible to according to the size of refrigerator 1 and expanded material injection head 34
Count and suitably determine.For example, it is possible to form groove portion 36 in the way of paper horizontal expansion, also
Can be with serrated topography grooving portion 36.But, in arbitrary pattern, all make foamed heat-insulating material
Inlet 33 is positioned on the projection section 37 of expanded material injection head 34.
It addition, groove portion 36 is not limited to be formed at the Vacuumed insulation panel 23 of side, it is also possible to cover
In lid, the Vacuumed insulation panel 23 of case 31 correspondingly forms.Such as, as shown in figure 17, end face,
The Vacuumed insulation panel 23 at ground and the back side is also formed with groove portion 36 such that it is able to dimensionally make
Foamed heat-insulating material is wittingly to the portion being difficult to be filled away from foamed heat-insulating material inlet 33
Shunting is dynamic.In addition it is also possible to the groove portion 36 transversely formed shown in Figure 17 is formed at than figure
Unfilled part more on the lower, is tackled in the paper position shown.
