In the refrigerator in Figure 10～Figure 13, the outer container 2 of steel plate system and form synthetic resin and the interior case 3 that constitutes and be filled in the heat insulating box 4 that unshowned foamed heat-insulating material between two casees 2,3 is formed in front openings.Two opposite opened

doors

7,8 in the left and right edges portion of the peristome 5 that is supported in this heat insulating box 4 by reversing by hinge up and down constitute peristome 5.

At the edge of the opening 5 of the heat insulating box 4 that is positioned at the part on

door

7,8 the non-pivotal support side separately guide member 9 is set opposed to each other respectively up and down.On guide member 9, form guiding groove 10.

Door

7,8 is made of pivot member 11,12,

outer frame member

15,16,

inner panel

21,22 and heat-barrier material 23.The

inward flange

17,18 of door

24,25 of non-pivotal support side.Liner 28 seals in the refrigerator 30 by adherence on the leading edge of the outer container 2 of the opening 5 of heat insulating box 4 when

door

7,8 is closed.

In the outside of the longitudinal wall 24 of the inboard of the liner 29 of the non-pivotal support side that is positioned at door 7 the insides the slightly spacer body 31 of brachmorphy shape of section is installed in addition.Flap 32 is fixed on the stiffener 33 of heat-barrier material 23 sides by screw 34 in two positions up and down of the lateral surface of longitudinal wall 24.Spacer body 31 reverses on the reverse shaft 35 that freely is supported in this flap 32.Spacer body 31 is that opening 5 edge framves are being extended up and down up and down and than the guiding groove 10 of guide member 9 up and down, guide member 9, the short slightly size in interval of guiding groove 10 with length.Frontal plane is installed steel plate 36 as shown in Figure 3 as the plane.

The lower end is outstanding along the vertical direction respectively thereon in addition forms projection 37 as fitting portion.Flap 32 is by forming two notch 38 up and down and be inserted in the spacer body 31 and making above gyroaxis 35 is positioned at from the hinder marginal part in door 7 sides of spacer body 31.Insert the spring members of being made up of helical spring 39 in this reverse shaft 35, make an end and flap 32 chimeric, the other end is chimeric with the pawl 40 in the spacer body 31 that leaves from reverse shaft 35.So, by helical spring recuperability spacer body 31 often can turned round like that along clockwise direction shown in the arrow 410 of Figure 12.

The following describes action by the door gear of above-mentioned such prior art that constitutes.

Spacer body 31 remains on shown in the dotted line among Figure 12 like that in door 7 opened state by the recuperability of spring members 39, and longitudinal wall 24 lateral surfaces along door inner panel 21 are connected under the state of screw 34.Under this original state, user's hand bumps because of carelessness behind spacer body 31, even make its counter clockwise rotation in Figure 12, still can return to original state by spring members.The angle of reversing of this action and spacer body 31 is irrespectively carried out.So the back door 7 that spacer body 31 reverses is closed in the same old way, can prevent to collide the breakage that causes on the teat of guide member 9 because of the projection 37 of spacer body.

When then door 7 was closed, the curved surfaces that almost enter in the guiding groove 10 in the guiding groove 10 of spacer body 31 slided, and spacer body 31 is along be that the center is revolted spring members 39 and reversed with reverse shaft 35 counter-clockwisely.Projection 37 enters into the deep of guiding groove 10.Otherwise when door 7 was opened, projection 37 was slided along the curved surface in the guiding groove 10.At this moment spacer body 31 reverses clockwise by the recuperability of spring members 39, almost turns back to original state.

Yet in the formation of above-mentioned prior art, spacer body 31 is installed on the outside of door 7 longitudinal wall 24.Therefore at two 7,8 when closed, 30 tightness is kept finely by liner 29 in the refrigerator.When opening, spacer body 31 reverses the outside of longitudinal wall 24.Therefore spacer body 31 space that must in

door

7,8, be provided for reversing.That is to say and to make

longitudinal wall

24,25 move to the pivotal support side of door.Therefore reduced the food storing space in the

door

7,8, when taking in food, the user has been felt inconvenient.

In addition, when door 7 opened and closed, the jut 37 of spacer body 31 slided along guiding groove 1090 degree of guide member 9 with reversing.Therefore projection 31 increases with the friction factor of guiding groove 10.Make the power of opening the door of door 7 become big, when door is closed, the user is felt inconvenient.

In addition,, but become the occasion of incomplete closure, the possibility that rises the food freshness is descended because of temperature in the refrigerator is arranged at reaction force because of frictional force and spring members 39 even the user thinks that door is closed.

In addition, spacer body 31 is because of 30 positions in refrigerator fully, and becomes when door is closed by the state of the cooling of the cold air in the refrigerator, and therefore the steel plate 36 that constitutes in spacer body also is cooled.Steel plate 36 is because of contacting often dewfall with the refrigerator outside.Therefore must in spacer body, connect member (for example heater) as the measure of correspondence as pyrotoxin.Thereby the caloric receptivity of refrigerator is increased, its power consumption is increased.
