As above-mentioned, in the insulated door 1 in the present embodiment 1, vacuum heat insulation material 5 is arranged in the middle of the summary of outside plate 2 and inner panel 4, is embedded in the foam heat insulating material 7 of hard polyurethane foams system, so vacuum heat insulation material 5 can be not directly and outside plate 2 and inner panel 4 thermo-contacts.Thus, the heat of outer gas and inner heat (cold air) can be avoided being transmitted to the heat bridge phenomenon that the metal evaporation plastic sheeting of vacuum heat insulation material 5 causes by outside plate 2 and inner panel 4 heat, can provide heat-insulating efficiency good insulated door.
In addition, vacuum heat insulation material 5 can directly not contact with inner panel 4 with outside plate 2, so can not provide cheap and the good insulated door of aesthetic appearance owing to vacuum heat insulation material 5 and the cavity (space) of critical generation of outside plate 2 and inner panel 4 or the difference of hard polyurethane foams system foam heat insulating material 7 shrinkage factors cause outside plate 2 and inner panel 4 surfaces to go up generation depression and distortion.
And vacuum heat insulation material 5 is supported and fixed on by support component 6 in the foam heat insulating material 7 of hard polyurethane foams system, thus, can be with operability preferably, the installation site does not have to bury underground with departing from and is fixed in the heat-barrier material.
About the support component 6 that supports vacuum heat insulation material 5 is fixed on, about between the relative the doorframe 3 or medial surface or the edge of adjacent doorframe 3.Thus, mounting groove and the support component 6 that is arranged on the door seal (not shown) on the peripheral part of an inner panel 4 can not interfered.Promptly, do not worry producing on the heat-barrier material side of sealing gasket mounting groove of an inner panel the not filling part of hard polyurethane foams, the sealing gasket mounting groove can be fully bonding by hard polyurethane foams, so sealing gasket is difficult to come off, and can access have sufficient intensity on the structure, the refrigerator of insulated door that reliability is high.
In addition, use the face tilt setting of support component 6, the stoste of injection hard polyurethane foams above vacuum heat insulation material 5 with vacuum heat insulation material 5 relative outside plates 2.The stoste of Zhu Ruing only arrives outside plate 2 from the downside (lower end side of inclination) that vacuum heat insulation material 5 tilts like this, so the stoste that arrives 2 of outside plates flows from one-sided (Fig. 7 from the left side to the right) of insulated door 1, arrives the doorframe the inside post-foaming of opposition side.Therefore, the mobile of hard polyurethane foams stoste is a direction, and 2 of outside plates are gone up the hard polyurethane foams stostes can not prevent that cavity (space) from producing from left-right collision, can provide not have on the outside plate 2 to be out of shape, insulated door that aesthetic appearance is good.
