Abstract
The utility model relates to a refrigerator mounted with a local vacuum heat insulation plate which is characterized in that the inner part of a refrigerator cabinet is provided with the local vacuum heat insulation plate; the local vacuum heat insulation plate is positioned at the position of an evaporator, wherein, the evaporator is positioned on the inner surface layer of the refrigerator cabinet, and the local vacuum heat insulation plate is positioned on a relevant position on the outer surface layer of the refrigerator cabinet. A hard polyurethane foaming layer is adhered between the inner surface layer and the outer surface layer of the refrigerator cabinet. The utility model can effectively reduce the heat conductivity factor of the refrigerator cabinet, decrease the heat duty of the refrigerator, and decrease the energy dissipation.
Description
Technical field:
The utility model relates to refrigerator, a kind of refrigerator that the parital vacuum heat-insulating shield is housed of more specifically saying so.
Background technology:
The refrigeration system of refrigerator comprises parts such as compressor, condenser, evaporimeter, and for the coldest, evaporimeter is the low-temperature receiver of refrigerator with wherein evaporimeter, and its temperature not only is lower than the refrigerator body external temperature, also is lower than the internal temperature of refrigerator body, forms the bigger temperature difference.Existing refrigerator generally adopts the hard polyurethane foam material as the heat insulation layer material.In process of production, with high pressure foaming machine PPG, isocyanates and blowing agent are injected after the high pressure mixing in casing and the door body by a certain percentage and to carry out chemical reaction, the hard polyaminoester that reaction forms has certain rigidity and intensity, can supporting box and a door body, have more good heat-insulating property, to satisfy the needs of refrigerator functions and performance.
But for evaporimeter, because the temperature difference is bigger, existing hard polyurethane foam layer can not reach desirable effect of heat insulation, causes the loss of cold.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of refrigerator that the parital vacuum heat-insulating shield is installed being provided, to reduce cold consumption, reduce refrigerator power consumption, to improve refrigeration.
The technical scheme in the invention for solving the above technical problem is:
Design feature of the present utility model is that the parital vacuum heat-insulating shield is set in refrigerator body, described parital vacuum heat-insulating shield is positioned at place, evaporimeter position, wherein, evaporimeter is positioned at the endosexine of refrigerator body, the parital vacuum heat-insulating shield is positioned at the extexine of relevant position refrigerator body, and the hard polyurethane foam layer is bonded in therebetween.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model has reduced the thermal conductivity factor of refrigerator body effectively by improving insulating layer structure, reduces the thermic load of refrigerator, reduces energy loss.
2, partial structurtes setting of the present utility model when improving effect of heat insulation, has effectively limited the increase of complete machine cost, obtains cost performance preferably.
3, the utility model is simple in structure, and is easy to implement.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Number in the figure: 1 evaporimeter, 2 refrigerator bodies, 3 vacuum heat-insulating plates, 4 hard polyurethane foam layers
The specific embodiment:
Present embodiment is provided with at evaporimeter.
Referring to accompanying drawing, present embodiment is in the refrigerator body 2 at place, evaporimeter 1 position vacuum heat-insulating plate 3 to be set, and the hard polyurethane foam layer 4 in vacuum heat-insulating plate 3 and the refrigerator body 2 bonds mutually.
Shown in the figure, evaporimeter 1 is positioned at the endosexine of refrigerator body 2, and parital vacuum heat-insulating shield 3 is positioned at the extexine of relevant position refrigerator body 2, and hard polyurethane foam layer 4 is bonded in therebetween.
In concrete the enforcement, vacuum heat-insulating plate 3 constitutes vacuum cavity by facial mask, and this vacuum cavity is to form vacuum in the annular seal space that is formed by facial mask, is filled with mineral wool or polyurethane foam in the vacuum cavity, and facial mask can be aluminium sheet or the polyester sheet that approaches.Vacuum heat-insulating plate 3 is embedded in before foaming on the relevant position in the refrigerator body 2, foaming final vacuum heat-insulating shield 3 and the hard polyurethane foam layer formation refrigerator lining that combines.
Because the vacuum state of vacuum heat-insulating plate, its thermal conductivity factor is far smaller than the hard polyurethane foam layer.By at the local vacuum heat-insulating plate of installing of refrigerator body, can reduce the thermic load of refrigerator efficiently, thereby reduce the power consumption of refrigerator, improve refrigeration performance.
Same version, this vacuum heat-insulating plate also can be arranged in the refrigerator body on other position with big temperature difference, as corresponding positions such as condenser, compressors etc.
