CN203802320U - Vacuum and thermal-insulation heat-preservation cage for dish - Google Patents

Abstract

The utility model is a vacuum and thermal-insulation heat-preservation cage for dish, which is based on an existing heat-preservation cage for dish. The vacuum and thermal-insulation heat-preservation cage is characterized in that an upper cylinder of each layer of heat-preservation cage is made of a nonmetallic material with low thermal conductivity; the lower opening of each heat-preservation cage is sealed; the lower part of each cylinder is formed by sleeving two metal cylinders with sealed tops so as to form a vacuum thermal-insulation cylinder with a double-layer structure, and a vacuum gap is reserved between two layers; the lower bottom opening sealing plate of the upper cylinder is concentrically and tightly fixed onto the top surface of the top end sealing plate of the lower cylinder; or, each layer of heat-preservation cage is formed by sleeveing two cylinders with metal top ends to form a vacuum thermal-insulation cylinder with a double-layer structure and a vacuum gap is reserved between two layers; a vacuum and heat-insulation upper cylinder is formed by pressing a concentric convex circle on the top end sealing plate of the lower part cylinder outer cylinder from the inner side to the outer side; each layer of vacuum thermal-insulation heat-preservation cage for the dish can be mutually inserted, so that multiple layers can be combined. The vacuum and thermal-insulation heat-preservation cage is good in appearance, durable, good in quality, and good in the heat-preservation effect.

Description

Vacuum heat-insulation dish heat insulation cage

Technical field

The utility model relates to a kind of dish heat insulation cage with vacuum mode heat-insulation and heat-preservation.

Background technology

According to authorizing and the disclosed patent No. is: described in two parts of utility model patents of ZL201020565329X and ZL2011204672673 can the overlapping combination of multilayer inserting dish heat insulation cage, the basic structure of its every one deck Thermal insulation cage is: top cylinder external diameter is less than bottom barrel bore and at upper and lower cylinder delivery position, has been provided with the cylindrical plastic housing of hermetic rigidity diaphragm plate, in the inner chamber of lower housing portion cylinder, be close to the cylindrical shape foam layer that cylindrical wall surrounding and diaphragm plate are lined with the flat envelope in top of heat insulation function, lower housing portion mouth cylinder opening's edge and foam layer mouth cylinder opening's edge one are reinstated the smooth sealing of plastics circle seal that a cross section is dihedral.Such structure and material, though also have good heat insulation effect, but still not fully up to expectations: be 1. that material is plastic materials, and plastic materials easily aging, appearance tactile impression is poor; 2. being that heat preserving mode mainly adopts foamed plastics, is the heat insulation effect of obtaining, and foam heat-insulation layer is thicker, makes the bottom cylindrical wall of every layer of modified dish heat insulation cage thicker, dexterous not.

Summary of the invention

The technical problems to be solved in the utility model is: the material of main part of every one deck dish heat insulation cage adopts texture excellence and long-lived metal material, Thermal insulation cage more wall is thin compact dexterous, to overcome the problem that metal material thermal conductivity is strong simultaneously, make the heat insulation effect of Thermal insulation cage still keep good.

The technical scheme that the utility model adopts is: having on the basic structure basis of diaphragm plate in the middle of cylinder up and down of existing dish heat insulation cage, the low nonmetallic materials manufacture of thermal conductivity and the flat envelope of nonmetallic materials for mouth of going to the bottom for the top cylinder of every one deck Thermal insulation cage, bottom cylinder stacks formation vacuum heat-insulation cylinder double-deck, that interlayer is vacuum voids by the cylindrical sleeve of the flat envelope in two metallic tops, mouthful flat shrouding bottom surface of going to the bottom of top cylinder is close to one heart and is fixed on the flat shrouding end face in cylinder urceolus top, bottom, and making main body is that metallic is equipped with part nonmetallic materials type vacuum heat-insulation dish heat insulation cage, or: every one deck Thermal insulation cage, with the cylindrical sleeve of the flat envelope in two metallic tops stack form double-deck, interlayer is the bottom cylinder of the vacuum heat-insulation of vacuum voids, the flat shrouding in top of inside and outside cylinder is configured to the diaphragm plate of vacuum heat-insulation, on the flat shrouding face in the urceolus top of this vacuum heat-insulation bottom cylinder, mold pressing goes out a concentric raised circle as the top cylinder of vacuum heat-insulation from inside to outside, the coated heat insulation rete of rubber and plastic or the not coated heat insulation rete of rubber and plastic on this dome circle, top cylinder, the triangular vacuum voids of bottom cylinder and diaphragm plate forms overall vacuum thermal insulation layer, this just becomes all-metal matter type vacuum heat-insulation dish heat insulation cage, the lower end nozzle of every one deck vacuum heat-insulation dish heat insulation cage bottom cylinder is reducing or straight mouth, and the lower end nozzle internal diameter that the lower end nozzle external diameter of bottom cylinder is less than top cylinder internal diameter or bottom cylinder is greater than top cylinder external diameter, every one deck vacuum heat-insulation dish heat insulation cage is symmetrical arranged two handle ears or does not establish handle ear in bottom cylinder outside, the top cylinder that every one deck vacuum heat-insulation dish heat insulation cage can overlap another layer of vacuum heat-insulation dish heat insulation cage of insertion by its underpart mouth cylinder is carried out in layer freely up superimposed assembling.

The beneficial effects of the utility model are: main body is that metallic is equipped with part nonmetallic materials type vacuum heat-insulation dish heat insulation cage, the appearance tactile impression of every layer of Thermal insulation cage is mainly beautiful metallic, bottom wall thickness of cylinder is also very little, also dexterousr, top cylinder adopts the low nonmetallic materials of thermal conductivity simultaneously, during superimposed insulation, heat is difficult for scattering and disappearing from the conduction of bottom mouth cylinder, this makes the overall radiating rate of whole Thermal insulation cage less, thereby makes Thermal insulation cage have good heat insulation effect when having beautiful metallic outward appearance.All-metal matter type vacuum heat-insulation dish heat insulation cage, because every layer of Thermal insulation cage all material adopts vacuum heat-insulation metal material, makes the texture of whole Thermal insulation cage and associative perception very good, material is durable in use, the wall thickness of Thermal insulation cage is also minimum, and the dexterousst, heat insulation effect is also good.
