The specific embodiment

Fig. 1 shows the perspective view according to refrigerating plant door of the present invention, and what illustrate is towards the rear side of the refrigerating plant door of the inside of refrigeration unit when being in assembled state.Door comprises by metal sheet and forms inwall 2 with the after-opening in the outer wall 1 of generation flat rectangular shape and the outer enclosed wall 1 that formed by the deep-drawing plastics with known manner.The chamber of being defined by outer wall 1 and inwall 2 is filled with the heat insulation foamed material.

Inwall 2 has the level and smooth neighboring area 3 that is fixed to outer wall 1.The outward flange of inwall 2 is hidden in the below of peripheral magnetic seal spare 4.The central area 5 of inwall 2 is designed to crowned; Edge and lower edge be to perimeter region 3 direct transition thereon, and all be formed with shallow grooves 6 in right hand edge and left hand edge in each case.Central area 5 be adjacent to groove 6 and each other dorsad side shoulder 7 be respectively equipped with the paired interlock locking protuberance 8 that is provided with equal height, thereby, only can see those interlocks locking protuberances in the left-hand side shoulder 7 in the drawings.Supporting plate 9 just in time extends across the whole width of central area 5 in the lower horizontal of every pair of interlock locking protuberance 8.

In the horizontal cross-section, central area 5 has in the center to the broad warp shape of inside turn, make supporting plate 9 in each case in the degree of depth of center greater than the degree of depth of the right hand or left hand border area at them.The curvature of the inwall 2 in the recessed portion of central area is little.The point P1 of the level cross-sectionn of inwall, the tangent line at P2 place represent that with Reference numeral T1, T2 described tangent line intersects with the minimum angles of all paired points in cross section; Their crossing angle

Greater than 150 °.As the result of this small curve, the formation of recess does not need to make the material production of inwall 2 significantly to stretch.Therefore, the stretching of inwall 2 on its whole zone is significantly less than the stretching of traditional inwall of the post with the interlock of carrying locking protuberance.Therefore, for the employed material of inwall, the original depth that reduces is feasible, so that realize identical bearing capacity with the situation of traditional inwall.Because recess, the good utilization in space is simultaneously accomplished.

Door storage unit 10 and they are fixed to the structure of fixed part of inwall 2 more clearly referring to Fig. 2 and 4, Fig. 2 and 4 correspondingly show along the vertical cross-section of the line II-II among Fig. 4 and along the line IV-IV among Fig. 2 by horizontal component cross section according to the inwall 2 and the door storage unit 10 of the first embodiment of the present invention.
