Description

Vacuum heat-insulating container

Technical field

This utility model relates to a kind of vacuum heat-insulating container.

Background technology

Vacuum heat-insulating container is the product commonly used during people live, as it is shown in figure 1, in it often includes Wall 1, be set in the outer wall 2 outside inwall 1, the inside and outside interlayer 3 being arranged between inwall 1 and outer wall 2, It is arranged on bottom outer wall 2 and reserved vacuum hole 4, is arranged on for taking out air in inside and outside interlayer 3 The vacuum cave 5 being connected on outer wall 2 and with vacuum hole 4 and the envelope material 6 being placed in vacuum cave 5. In vacuum process, melt during high-temperature vacuum by being positioned over the envelope material 6 in vacuum cave 5 in advance Block vacuum hole 4 and vacuum cave 5, thus reach the effect that vacuum layer seals.Aborning, outer wall Pipe shaft and pipe back welding connect after, vacuum heat-insulating container is inverted, and envelope material 6 is placed in vacuum cave 5, then is transported into Vacuum drying oven, during transporting, material rocks, and the envelope material often stifled vacuum hole 4 of mobile pressure, at vacuum drying oven Due to the envelope stifled vacuum hole 4 of material 6 pressure during interior evacuation, make the air in inside and outside interlayer 3 get rid of and have some setbacks, Residual air, the container after vacuum has residual air to conduct heat due to interlayer, causes hot water thermal amount stream in cup Losing very fast, thus vacuum heat-insulating container heat insulation effect is the best, cause often doing over again guarantor in process of self-test The cool-bag that temp effect is the best, causes manpower, the waste of material resources, adds cost, and is incubated not Good cool-bag comes into the market, and can affect and use to client.

Accompanying drawing explanation

Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:

Fig. 1 is the sectional view of prior art；

Fig. 2 is this utility model sectional view before vacuum；

Fig. 3 is this utility model sectional view after vacuum.

Detailed description of the invention

Embodiment: as Figure 2-3, this utility model provides being embodied as of a kind of vacuum heat-insulating container Example, it includes inwall 10, is set in the outer wall 20 outside inwall 10, is arranged on inwall 10 and outer wall Inside and outside interlayer 30 between 20, it is arranged in inside and outside interlayer 30 and is welded to connect inside outer wall 20 Metalwork 40, vacuum cave 42 between outer wall 20 and metalwork 40, it is positioned at outer wall 20 and ring Around metalwork 40 inner supporting circle 50, the envelope material 60 being placed in vacuum cave 42, be coated in outside outer wall 20 Baking vanish layer 70 on side and for protecting the protection set 80 of baking vanish layer 70.

Inwall 10 is placed in outer wall 20, wherein outer wall 20 include outer pipe shaft 22 and with outer pipe shaft 22 At the bottom of the outer tube being welded to connect 24, at the bottom of outer tube, 24 dock weld with outer pipe shaft 22 plane of structure and have inner supporting circle 50 Supporting, in inner supporting circle 50 one end bulging enters at the bottom of outer tube 24, and other end bulging enters in outer pipe shaft 22, 24 are made at the bottom of outer tube to align with outer pipe shaft 22 end face, then end face welding.On inner supporting circle 50 fluted 56, The passage 54 being connected with groove 56, outside inner supporting circle 50 is fixed on by sheet metal 52 spot welding simultaneously At the bottom of pipe on 24.

Metalwork 40 is substantially u-shaped, and is welded to connect with outer wall 20, and its center is provided with and curb pins The vacuum holes 44 that are connected of layer 30, and 24 it is also equipped with through hole 240 at the bottom of the outer tube in the outer wall 20 of correspondence, And vacuum hole 44 overlaps with the centrage of through hole 240, and envelope material 60 also has a centre bore, and centre bore Centrage overlaps with the centrage of vacuum hole 44.Once vacuum, the centre bore heat seal bond of envelope material 60 Together, to block vacuum hole 44, after vacuum, through hole 240 blocks, outward from outside weldings weldering thing 90 See attractive in appearance.

Protection set 80 is plastic protective sleeve, and it fits tightly with baking vanish layer 70, seamless, waterproof, with Time containers anti-skidding, the anti-collision of protection set 80 and the lacquer painting that causes comes off or container deformation, also can prevent Time sometimes hot and sometimes cold, baking vanish is different from the rustless steel coefficient of expansion and cause coming off, and has aerofluxus bottom protection set 80 Hole 82.

During production, in advance by envelope material 60 welding on metalwork 40, the vacuum hole 44 of reprocessing aerofluxus With run through the centre bore of envelope material 60, then seal material 60 and be welded on outer wall 20 together with metalwork 40, then In feeding vacuum drying oven.The air in inside and outside interlayer 30 is extracted out, then by vacuum hole 44 and through hole 240 Heating, seals the center hole part heat seal bond of material 60 together in heating process, block vacuum hole 44, Thus this utility model envelope material when transporting material will not move closure vacuum hole, reduces cool-bag bad Product, reduce cost, improve enterprise competitiveness, and inner supporting circle makes material at butt welding at the bottom of outer pipe shaft and outer tube Material thickeies, and intensity enhancing is unlikely to deform, and improves butt welding yields, it is achieved the butt welding of relatively thin material, Fixing at the bottom of inner supporting circle is welded to outer tube simultaneously, make cool-bag not have abnormal sound, inner supporting circle is fluted aerofluxus Hole, the gas produced during welding is discharged by groove steam vent, solves the relatively thin 0.7mm of cool-bag Following material is difficult to butt-welded technological difficulties, and plastic protective sleeve improves cool-bag heat insulation effect, protects Vernix face is not come off by collision, also increases antiskid function, and during colder environment, hot water cleans cool-bag, Slow down sometimes hot and sometimes cold variations in temperature, prevent lacquer painting different from the rustless steel coefficient of expansion and cause coming off, increase Cool-bag service life, reduce waste.Additionally envelope material is placed in interlayer, and the most anti-oxidation is anti- Only envelope material clashes into broken, is incubated bad, increases cool-bag service life.

Certainly above-described embodiment is only for illustrating technology of the present utility model design and feature, its object is to allow Person skilled in the art will appreciate that content of the present utility model and implements according to this, can not limit with this Protection domain of the present utility model.All done according to the spirit of this utility model main technical schemes Equivalent transformation or modification, all should contain within protection domain of the present utility model.
