The specific embodiment
As shown in figures 1 and 3, the food boxes among the present invention include inner box 2, that an outer box 1, is used for food container be located at the refrigerating sheet 3 between outer box 1 and the inner box 2 and be located at refrigerating sheet 3 and outer box 1, inner box 2 between fast conducting unit.Wherein:
Outer box 1 includes top cover 10, box body 11 and by the fixing bottom 12 of attaching parts (as: screw bolt and nut) and box body 11, is provided with an adapter plate 15 that is used to be provided with refrigerating sheet 3 and power supply component between bottom 12 and box body 11.Bottom 12 offers a through hole 14 in its bottom, and is fixed with a cover plate 13 at these through hole 14 places, and this cover plate 13 is provided with at its outside face a plurality ofly can accelerate the fin 16 that heat (cold) energy distributes.The box body 11 midway location place of portion within it has an aluminium chassis 17 by bolt, fixed by nut, by this chassis 17 box body 11 inside are divided into two parts up and down, wherein the space, top is used to place inner box 2, and the space, lower part is used to be provided with refrigerating sheet 3, fast conducting unit and power supply component.
As shown in Figure 3 and Figure 4, refrigerating sheet 3 is located on the adapter plate 15 between bottom 12 and the box body 11 by anchor fitting, and lower surface is provided with a fast conducting unit thereon, promptly one is located in refrigerating sheet 3 and the outer box at the end, another then is located between refrigerating sheet 3 and the inner box outer bottom, so that heat (cold) energy that refrigerating sheet 3 produces can conduct to required position respectively.One fast conducting unit includes the heat-conducting oil pipes 40 that is fitted in refrigerating sheet 3 upper surfaces and at least one and is pressed on the red copper guide plate 41 on heat-conducting oil pipes 40 surfaces by anchor fitting, and wherein heat-conducting oil pipes 40 is the high copper pipe of a conductance, and 5 * 10
-5Vacuum under in copper pipe, be injected with some flowing power and enliven material, this activity material is the material mixing material that the molecule activity diffusion is exceedingly fast, the volume of this mixing material accounts for half of copper pipe volume, the two ends of copper pipe after injecting mixing material engage by laser, utilize this copper pipe to pass to the copper pipe other end to the temperature on refrigerating sheet 3 surfaces in 3～4 seconds.Red copper guide plate 41 is the U type, an end of this red copper guide plate 41 and heat-conducting oil pipes 40 leak-tight joints, and chassis 17 closed contacts of the other end and inner box bottom.Food boxes among the present invention is to utilize heat-conducting oil pipes 40 that heat (cold) energy on refrigerating sheet 3 surfaces is passed to red copper guide plate 41 fast, pass through the conduction of red copper guide plate 41 again, further heat (cold) energy that refrigerating sheet 3 is produced is passed to chassis 17 fast, and the foods in the inner box 2 are heated or refrigerate.The structure of another fast conducting unit and the structure of above-mentioned conduction device are identical, just symmetry is arranged between refrigerating sheet 3 and the bottom 12, wherein red copper guide plate 41 is combined closely with cover plate 13 after passing adapter plate 15, and at high speed dissipates heat (cold) energy that refrigerating sheet 3 produces.
Anchor fitting includes about in the of two symmetry and is coated on the coating member 50 and 51 of described refrigerating sheet 3 peripheries, and two pressing plates 52 that are respectively applied for fastening red copper guide plate 41 respectively, this pressing plate 52 is fixed on coating member 50 and 51 by screw 53, and red copper guide plate 41 is fitted in refrigerating sheet 3 surfaces closely.Because refrigerating sheet 3 is as thin as a wafer a semiconductor subassembly, therefore utilize coating member 50 and 51 refrigeration up and down, the pyrogenicity of refrigerating sheet 3 can be distinguished, to increase the effect of refrigeration or pyrogenicity, reduce the consumption of the energy, in each zone that separates, insert silica gel solvent 54 in addition, with the effect of further increase conductor refrigeration sheet.
As depicted in figs. 1 and 2, refrigerating sheet 3 can be supplied with direct current (DC), also can supply with alternating current.In space, box body 11 lower part, be provided with a battery case 6 that is used to place battery, as shown in Figure 1, the both positive and negative polarity at battery case 6 two ends links to each other with the two poles of the earth of refrigerating sheet 3 by a control circuit respectively, wherein the structure of control circuit, battery 7 and battery case 6 all adopts commercially available matured product, no longer describes in detail at this.As shown in Figure 2, in the space, lower part of box body 11, be provided with a voltage transformer 8, the plug 9 that the input end of this voltage transformer 8 and extends outer box is electrically connected, and mouth is connected in series with described refrigerating sheet 3 by a control circuit, this control circuit, voltage transformer and plug all adopt commercially available matured product, no longer describe in detail at this.Emphasize a bit in addition at this, above-mentioned direct current feeding mechanism with exchange feeding mechanism and can exist simultaneously, thereby can when going out, bring bigger convenience.
The other end of huyashi-chuuka (cold chinese-style noodles) is the hot junction after energising owing to the conductor refrigeration sheet with Peltier effect has, and the faster then cold junction temperature of the heat radiation low characteristic that heals, therefore the principle of work of food boxes is as follows among the present invention: at first refrigerating sheet can produce thermal energy at upper surface after energising, and produce cold energy at lower surface, after changing electrode, just in time be in inverse state; Heat (cold) energy that the refrigerating sheet upper surface produces is delivered in the red copper guide plate 41 by conduction oil under near vacuum soon by heat-conducting oil pipes 40 (HEAT TRANSFER COMPOUND), by red copper guide plate 41 energy is passed in the chassis made of aluminum 17 fast again, and further pass in the inner box 2, inner box 2 in-to-in foods are heated or refrigerate, simultaneously, cold (heat) energy of refrigerating sheet lower surface also conducts to red copper guide plate 41 by heat-conducting oil pipes (HEAT TRANSFER COMPOUND) under near vacuum, again by red copper guide plate 41 with cold (heat) energy conduction to the radiating fin 16 of cover plate 13, make in cold (heat) energy, outer conduction balance, after the conduction of quickening heat (cold) energy, can further bring into play the function of refrigerating sheet.
In sum, food boxes among the present invention can be at any time by requirement refrigeration of oneself or the food in the heating inner box 2, need only when promptly needing switch is shifted onto on the cold or hot position, just can in the time of subscribing, reach the effect of refrigeration or heating, refrigeration aspect temperature can be below 4 ℃, keep that food is fresh not to degenerate, and can meet the feed requirement more than 45～50 ℃ in temperature aspect the heating.
