Fig. 7 is the E-E line arrow instruction sectional view of Fig. 4.

As shown in Figure 7, the positioning rib 21a1 abutting with the back side of header board 22 (below) 22a and locate is formed at the internal face of upper plate 21a.This positioning rib 21a1 along header board 22 upper end-face edge portion in the lateral direction between handle portion 23a and handle portion 24a (with reference to Fig. 6).

In addition, the internal face of upper plate 21a be formed abut with the midfeather 23a3 of handle portion 23a and the positioning rib 21a2(that locates with reference to Fig. 6).This positioning rib 21a2 is in the position corresponding with midfeather 23a3, and (direction orthogonal with paper) is formed along the vertical direction.

The positioning rib 21b1 abutting with the back side of header board 22 (below) 22a and locate is formed at the internal face of bottom surface 21b.This positioning rib 21b1 along the lower edge section of header board 22 between side plate 23,24.

In addition, be formed at base plate 21b and forwards give prominence to and support the convex edge 21b2 of the lower end of header board 22.This convex edge 21b2 along the lower edge section of header board 22 between side plate 23,24.

Backboard 21c is configured to, on the whole above-below direction corresponding with refrigerating chamber 5, vegetable compartment 6, roughly the same with the distance of header board 22 or more than predetermined distance.In addition, backboard 21c is positioned at above-below direction between the upper edge and lower edge portion of opening portion 5s, 6s of refrigerating chamber 5, vegetable compartment 6.In addition, backboard 21c is configured to, with refrigerating chamber 5, on the whole left and right directions of vegetable compartment 6 correspondence, roughly the same with the distance of header board 22 (with reference to Fig. 5).

In the door 5a formed like this, in the whole space surrounded by upper plate 21a, base plate 21b, backboard 21c, header board 22 and side plate 23,24, be filled with foamed thermal insulating.Therefore, in the 1st embodiment, in the whole region corresponding with the opening portion 5s of refrigerating chamber 5, form the heat insulation layer R1 that thickness is T3.

In addition, header board 22 is configured to, and the convex edge 21b2 of base plate 21b is touched in end mode with lower edge abuts, and the convex edge 21a3 of upper plate 21a is touched in end mode with upper edge abuts, left side edge is supported by reflex part 23a5, and right side edge is (not shown by reflex part.Structure is identical with reflex part 23a5) support.That is, be configured to upper edge and lower edge and frame member (upper plate 21a, base plate 21b) touch, the front of left side edge and right side edge is covered by frame member (upper plate 21a, base plate 21b).

Thus, the header board 22 of the shape that left and right directions is long is not supported by frame member, so can increase the area from confirming above because of long leg (upper side edge edge and lower side edge) compared with above-below direction.Especially, because be positioned at the position of the middle body comprised before refrigerator 1A, so upper edge and lower edge are compared with left side edge and right side edge, be the position that user more easily confirms.Therefore, all exposed by the front of the upper edge and lower edge that make header board 22, thus can both emphasize smooth sense, the impression that user is jumbo storage space can be given again.

In addition, because the left side edge and right side edge being configured to header board 22 is covered by frame member (side plate 23,24), thus can, when hand is placed on handle portion 23a, 24a by user, prevent from contacting with the left side edge of header board 22 and posterior edges.

In addition, the state that also can be configured to the upper edge of header board 22 or at least one party of lower edge and frame member (upper plate 21a or base plate 21b) are touched makes front expose, and covers the opposing party with frame member.That is, be configured to make at least one party of edge part opposing upper and lower to make front expose under the state of touching with frame member, cover the opposing party with frame member.Thus, both reliably carry out the supporting utilizing frame member of header board 22, the area that tabular surface forwards exposes can be increased again.

In addition, each the size of header board 22 of glass can produce deviation.And, when being configured to cover the complete cycle up and down of header board 22 with the reflex part of frame member, if the size of header board 22 is larger than given size, then reflex part cannot be utilized to cover header board 22.On the other hand, when being configured to make the complete cycle up and down of header board 22 and the convex edge of frame member touch, if the size of header board 22 is less than given size, then header board 22 pairs of convex edges touch inadequate, header board 22 may come off from frame member.

Therefore, be configured to make at least one party of the edge part opposing upper and lower of header board 22 with the state of touching with frame member, front to be exposed, and cover the opposing party with frame member.Thus, a side of the edge part of header board 22 utilizes the reflex part of frame member reliably to support, and the convex edge of the opposing party and frame member touches, thus can adjust and allow the dimensional discrepancy of header board 22, and can increase and expose area before header board 22.

In addition, door 6a is also formed identically with door 5a, with vegetable compartment 6(with reference to Fig. 2) opening portion 6s(with reference to Fig. 2) in corresponding whole region, be configured to the heat insulation layer of the thickness of regulation.In addition, to be formed as the thickness T3 of the heat insulation layer R1 of the door 5a than refrigerating chamber 5 thin for the thickness of the heat insulation layer of the door 6a of vegetable compartment 6.

Next, contrast with comparative example and be described with reference to the action effect of accompanying drawing to the refrigerator 1A of the 1st embodiment.The figure of Fig. 8 to be the figure of the action effect of the door of the refrigerator that the 1st embodiment is described, Fig. 9 be other action effects of the door of the refrigerator that the 1st embodiment is described.Figure 13 is the key diagram of the effect corresponding with Fig. 8 of the door of the refrigerator of comparative example, Figure 14 is the F-F line arrow instruction sectional view of Figure 13, Figure 15 be the door of the refrigerator that comparative example is described by the figure of the effect corresponding with Fig. 7 of situation configured up and down, Figure 16 is the key diagram of the effect corresponding with Fig. 9 of the door of the refrigerator of comparative example.First, be described with reference to the drawer door 100 of Figure 13 and Figure 14 to comparative example.

As shown in figure 13, the top of drawer type door 100 above as comparative example is provided with the handle portion 101 pulling out drawer door 100 for putting hand (finger).This handle portion 101 is positioned at the substantially central portion of the left and right directions of door 100.

As shown in figure 14, the handle portion 101 as comparative example has at upper plate 100a the recess 101b that the vertical section of inserting hand (finger) from top is viewed as roughly U-shaped.The bottom surface 101b1 of this recess 101b is positioned at the position more leaning on above-below direction (vertical direction) below than the lower surface 10g2 of distance member 10g.

But, under the state that the door 100 as comparative example is closed, at the some P10(in handle portion 101 with reference to Figure 10) put hand (finger) when opening door 100, as shown in the hollow arrow of Figure 13, P10 will be put as benchmark, such as, be scattered in left direction, each power F11 of right direction, tiltedly lower left, tiltedly lower right and lower direction, F11, F12, F12, F13 as drawing stripping seal 25(with reference to Figure 14) power play a role.

Relative to this, under the state that the door 5a of the 1st embodiment closes, when hand (finger) being placed on the some P1(of handle portion 23a in left side with reference to Fig. 8) when opening 5a, as shown in the hollow arrow of Fig. 8, with a P1 for benchmark, such as, be scattered in each power F1 in right direction, tiltedly lower right and lower direction, F2, F3 be positioned at the seal 25(of the left and right directions (width) on the top of door 100 with reference to Fig. 5 as drawing stripping) power play a role.Herein, common drawer type door 100 is generally the pattern that left and right directions size (width dimensions) is larger compared with above-below direction size (height dimension).If this is because make height dimension excessive, then the food being accommodated in storeroom is become many because of the food received above by situation about burying, and the convenience of use reduces.Therefore, making left and right directions size (width dimensions) larger than above-below direction size (height dimension), thus easily receive arrangement, easily observing all collecting articles when pulling out drawer type door 100.

Like this, as in the door 100 of comparative example, because the substantial middle of the superposed left and right directions in handle portion 101, so for the seal 25, power F11 of left and right directions (width) on top, F11, F12, F12 both sides dispersion to the left and right (with reference to Figure 13) that are positioned at door 100.In addition, be equipped with seal 25 from a P10 towards the left and right sides, and seal 25 is close to by magnetic force generating unit and refrigerator main body, so in order to draw stripping seal 25 to need larger power.

Relative to this, in the door 5a of the 1st embodiment, the superposed bight of 23a, handle portion, so the near intersections of seal 25 relative to the above-below direction (short transverse) of the left and right directions (width) and door 100 left side that are positioned at door 100 top, apply power F1, F2 to the right.Therefore, inhibit the dispersion of the power for seal 25, larger stripping power of drawing plays a role to seal 25.In addition, because handle portion is positioned at the upper end of a 5a, thus when opening 5a, draw stripping power F1, F2, F3 bight to the seal 25 of four frame shapes plays a role, so can make to draw the power of stripping seal 25 to be less than comparative example.

In addition, when utilizing handle portion 23a to open 5a, as shown in Figure 5, using seal 25 by magnetic force generating unit 25b(with reference to Fig. 6) and the some P2(on right side (the contrary side of the left and right directions of handle portion 23a) that is close to reference to Fig. 5) as fulcrum, turning moment M1 acts on handle portion 23a, so easily can draw stripping seal 25.And, when utilizing handle portion 23a to open 5a, as shown in Figure 7, the point P3(of the downside (the contrary side of the above-below direction of handle portion 23a) be close to by magnetic force generating unit (with reference to Fig. 6) by seal 25 is with reference to Fig. 7) as fulcrum, turning moment M2 acts on handle portion 23a, so easily can draw stripping seal 25.And, producing moment M1, M2 for door 5a is because at the drawer frame 5b(of door 5a with reference to Fig. 2) be arranged at the side panel 10b(of refrigerator main body 10 with reference to Fig. 2) track 10h(reference Fig. 2) groove between, formed with the state arranging the space for successfully carrying out pull-out action.

Like this, by handle portion 23a being configured in the top of the left end of a 5a, and stripping seal 25 can be drawn by the power (pullout forces) less than the door 100 as comparative example (in the past), a 5a more easily being opened than ever, namely can open with less power.

In addition, in as 100 of comparative example, as shown in figure 14, by the recess 101b in handle portion 101, the heat insulation layer R100 of thickness T100 is produced on the top of door 100.Therefore, in the region of the thin heat insulation layer R100 of thickness T100, because the recess 101b in handle portion 101 easily turns cold, so produce dew (condensation) in handle portion 101, in addition, even if do not produce dew (condensation), the heat (cold air) in refrigerating chamber 5 also can be escaped, and becomes and is unfavorable for energy-conservation parts.In other words, if heat (cold air) is escaped, then the temperature in case rises, so have to cool in case, owing to exceedingly repeating such circulation, and impairs energy-saving.

In addition, as shown in figure 15, such as, be configured with refrigerating chamber 5 and vegetable compartment 6 up and down, a 100A(100 is configured with) at refrigerating chamber 5, vegetable compartment 6 is configured with a 100B(100) when, on above-below direction (short transverse), the seal 25A(25 of door 100A) and the seal 25B(25 of door 100B) share interval adiabatic wall 10f.In this case, because door 100A and door 100B is close at above-below direction, so the recess in handle portion 101 (bottom surface of recess) moves downwards, the part that the heat insulation layer R100 of thickness T100 is thin increases.Two chain-dotted lines of the part of heat insulation layer R100 thin for this thickness T100 with Figure 15 are represented, if make the thickness of thin heat insulation layer R100 increase, then produces the problem of the volume reducing in case.

Therefore, in the 1st embodiment, by handle portion 23a being arranged on the side of a 5a, thus do not produce the thin part of heat insulation layer R100, as shown in Figure 7, the whole region of the opening portion 5s of refrigerating chamber 5 can be closed, i.e. compartment size (size between distance member 10g and interval adiabatic wall 10f) between the upper and lower by the door 5a of the heat insulation layer R100 with thickness T3.

In addition, as shown in figure 16, such as, when front configuration refrigerator 300 of tank 200, the front of usual user stands in (crouching) refrigerator 300 is opened and is closed door 100A, 100B., in recent years, with the maximization of refrigerator, namely the degree of depth that there is refrigerator pulled out the also elongated trend of distance L100, so user self becomes an obstruction for 5a switch, cannot obtain the pull-out distance L100 of 100A, 100B.Therefore, be difficult to take out the food etc. of the inboard being positioned at the container (not shown) being placed in 100A, 100B.

Therefore, in the 1st embodiment, as shown in Figure 9, the side (left side or right side) standing in (crouching) refrigerator 1A by user, is placed on handle portion 23a(or handle portion 24a by hand) forwards pull out 5a, 6a, thus 5a, 6a can be opened.When opening 5a, 6a in such a case, as above-mentioned, be configured in the upper corner of 5a, 6a by handle portion 23a, 24a, and turning moment M1(is with reference to Fig. 5) and turning moment M2(with reference to Fig. 7) generation, 5a, 6a can be opened with power little than ever.
