Abstract
The utility model relates to a structure improvement of a case body or a door body of a refrigerator. The case body or the door body of the existing refrigerator is composed of an outer shell plate, a heat insulating layer, and a liner, wherein, the heat insulating layer is rigid polyurethane foam formed by expanding foam and filling, the environmental pollution and energy consumption are big, and the heat insulating property is poor. The utility model has the key technology that the heat insulating layer is added with a polyurethane vacuum heat insulating plate and is sealed by foam expanding hard polyurethane, the use amount of the foam expanding material is reduced, and the heat insulating property is improved.
Description
The utility model relates to the refrigerator production technical field, particularly about the improvement of the casing or the door body structure of refrigerator.
The casing of existing refrigerator or door body all have outer field Shell Plate, intermediate thermal insulating layer and nexine inner bag, middle heat-barrier material is all selected polyurethane rigid foam plastic (PURF) for use, because its good solid heat-barrier material that is present heat-proof quality, it is widely used in petrochemical industry, building trade and household electric appliances.Because the freon (CFC-11) of one of PURF primary raw material has strong destruction to ozone layer and is forbidden by time limit.For this reason, various substitutes and substitute technology develop.Up to the present, the environment-friendly type PURF of all substitutes and substitute technology, heat-proof quality all causes energy consumption to increase, thus the problem of not protecting of having brought out rings such as greenhouse effects.For VACUUM INSULATION PANEL, the content of two aspects of research of the development of open celled foam core and perforate rigid foam thermal insulation board vacuum sealing technique has been experienced in its generation.Existing vacuum insulation panel can reach following index: do not contain all banned substances in the foaming system fully and (comprise CFCS, HCFCs; ); Effective thermal conductivity≤0.010W/m, k, its compression strength 〉=120kp
aIts dimensional stability≤1.0%, its density≤40kg/m
3, the vacuum of thermal insulation board is better than 70P
a(～0.5 holder), and be applicable to production.Owing to generally adopt the stuffed heat insulated layer of polyurathamc in the refrigerator production at present, therefore do not see the material of pulling that to meet above-mentioned technical indicator and be applied in the refrigerator production.
The utility model purpose is to improve the heat-proof quality of refrigerator foaming layer, to reach energy-conservation, economize on electricity, lower consumption, be incubated, insulate.
Realize the technical scheme of above-mentioned purpose, key is to have used the VACUUM INSULATION PANEL that meets the relevant art index in the refrigerator foaming layer.Specifically, a kind of casing of refrigerator or door body, comprise the heat-barrier material RPUF in outermost Shell Plate, intermediate layer and the inner bag of innermost layer, in the RPUF in intermediate layer, be sealed with the more good VACUUM INSULATION PANEL of heat-proof quality.On thermal insulation board, also be connected with and make its reference column, and on the reference column both ends of the surface tack coat is arranged with respect to Shell Plate and inner bag location.
The vacuum insulation panel of being mentioned among the application, it does not contain any fluorine Lyons (comprising transitionality, as 141b etc.) material.The vacuum heat-insulation board core material adopts the open-cell rigid foam, and this open-cell rigid foam is different with common closed pore rigid foam.At first, the rate of closed hole that perforate is hard bubbled very low (～0%) percent opening then requires to reach 100%, and closed pore hard bubbles then opposite, rate of closed hole reaches more than 95%, adopts perforate to hard bubble just because of core, when it is found time to be packaged into product, gas is almost extracted totally in the foam, and its reciprocal of duty cycle is better than 70P
a(～0.5 holder), the heat transfer effect of gas disappears substantially, adds that encapsulation keeps vacuum, makes vacuum insulation panel show very good heat-proof quality.
The utility model greatly reduces the expanded material use amount owing to adopt the stuffed heat insulated layer of the better sheet material of heat-proof quality, thereby, not only effect of heat insulation doubles, and product cost is reduced significantly, and help improving the refrigerator quality, reach the environmental protection and energy saving double effects.
Description of drawings:
Fig. 1 is the utility model casing schematic diagram.
Fig. 2 is the utility model door body schematic diagram.
Embodiment: the casing of refrigerator or door body, its outermost shell body is generally selected the sheet metal punch forming, the innermost layer is the plastics inner bag, the centre is a thermal insulation layer, thermal insulation layer is divided into RPUF and VACUUM INSULATION PANEL, reference column bonds on vacuum insulation panel, reference column should be selected certain intensity for use but not too hard material such as polystyrene foam plastics, there is binding agent at the reference column two ends, one end is beneficial to thermal insulation board and is connected, other end and Shell Plate or inner bag bonding location is in case thermal insulation board displacement during foaming.Vacuum insulation panel can be located 2-4 on each face, and utilizes the existing foaming technique that generally adopts that RPUF is sealed in thermal insulation board six faces wherein.Like this, the thermal insulation layer performance doubles, and has reduced gas release again, helps reducing cost.
Claims (3)
1, a kind of casing of refrigerator or door body, comprise the heat-barrier material rigid polyurethane foam plastics (5) in outermost Shell Plate (1), intermediate layer and the inner bag (4) of innermost layer, it is characterized in that being sealed with the more good VACUUM INSULATION PANEL of heat-proof quality (2) in the RPUF in intermediate layer.
2, the casing of refrigerator according to claim 1 or door body is characterized in that also being connected with on the VACUUM INSULATION PANEL and make its reference column (3) with respect to Shell Plate and inner bag location.
