3. repeating step 1 or 2 makes sunshine focus on pot (5) bottom surface exactly, and at this moment, the solar energy that focuses on the bottom of a pan is transformed into heat energy, the interior food of heating kettle (5).
4. with the running of the work earth, the sunlight of former focusing will slightly depart from the bottom of a pan, need repeating step 1 and 2, and appropriateness is adjusted; Make sunlight focus on the bottom of a pan again, carry out up to whole foods.
5. finish using, earlier pot (5) is taken off, remove again and connect overflow dish (14) stay-warm case (6) and pot frame (7), take off subsequently and pay reflective surface (8), remove main reflective surface (9) and amount to into suitcase, will pay reflective surface (8) and be put in the case.Rotary worm (2) makes " V " shape plate (13) and support (10) keep minimum volume then, shrinks fulcrum arm (12), and with whole reflective surface support (10) and pot frame (7), stay-warm case (6) etc. is put in the support case (as Fig. 5).
Characteristics of the present utility model and development:
1. according to paraboloid of revolution theory, get four curved surfaces of associated on this curved surface, form reflective surface of the present utility model, wherein two is main reflective surface (9), pays reflective surface (8) for two.Two pairs of reflective surfaces (8) play a part to strengthen or auxiliary main reflective surface (9) foundation different with the relative position of main reflective surface (as Fig. 1), pay reflective surface (8) or work the intensity of illumination (as Fig. 6) that strengthens main reflective surface (9); Or rise to replenish main reflective surface (9) in the morning or intensity of illumination (as Fig. 3) at dusk; Or replenish the intensity of illumination (shown in chain-dotted line H among Fig. 1) that reflective surface reverberation that high latitude area causes because of sun altitude is less converges the not main simultaneously reflective surface in angle (9).
2. two main reflective surfaces (9) can be folded into a suitcase, and two pairs of reflective surfaces (8) can place in this case, make volume quite little, and it is very convenient to carry, and play the effect of the reflective facial mask of protection simultaneously.
3. main reflective surface (9) and pay reflective surface (8) and support (10) etc. is all used light weight, material manufacturing that intensity is big makes its weight little, and the precision height is effective.
4. a main reflective surface (9) and pair reflective surface (a 8) inner surface carry out vacuum aluminum-coated, and the aluminium film is coated with matcoveredn outward, can strengthen reflecting effect, increases the service life.
5. reflective surface support (10) adopts worm gear (1) worm screw (2) structure, elevation angle that can stepless adjustment reflective surface, and have the function that makes main reflective surface (9) and the self-locking of pot frame (7), the assurance pan is steady; Reflective surface support (10) adopts fluted disc (3) and pin block (4) structure, the azimuth that can adjust main reflective surface (9) and pay reflective surface (8), and it is very convenient to operate.Also can adopt the photoelectricity solar tracking system, adjust the elevation angle and the azimuth of reflective surface automatically, reach self-focusing purpose according to the user's of developed country needs.Its principle such as Fig. 7: photoelectric tube (15) is housed on the main reflective surface (9), and micro machine (16) is equipped with in worm screw (2) end, and micro machine (17) is housed on the reflective surface support (10), and its shaft end gear (20) is meshed with wheel disc (3).Photoelectric tube (15) axis is parallel with the paraboloid of revolution axis of reflective surface (9) and (8), when reflective surface (9) and (8) focus on pot (5) bottom surface with sunlight, reflective surface surface of revolution axis is parallel with sunray, at this moment, sunshine is also injected in the photoelectric tube (15) simultaneously, make it produce photoelectric current, after amplifying, galvanomagnetic-effect takes place, and the circuit of cut-out motor (16) and (17) and battery (18), motor (16), (17) stop operating, main reflective surface (9) and pair reflective surface (8) are also static, have guaranteed that sunlight focuses on pot (a 5) bottom surface.Because the earth rotates, Jiao group of sunshine is offset in pot (5) bottom surface, at this moment, photoelectric tube does not have sunlight in (15) yet, and photoelectric current also disappears, former cut motor (16), (17) circuit is switched on, motor (16) and (17) rotate and drive respectively worm screw (2) and wheel disc (3) rotates, and elevation angle and the azimuth adjusting main reflective surface (9) respectively and pay reflective surface (8) make sunlight focus on pot (5) bottom surface again.Simultaneously, sunlight also is shining in the photoelectric tube (15) once more, and the galvanomagnetic-effect of its photoelectric current is cut off the electric current of motor (16) and (17) once more, makes reflective surface (9) and (8) be stable at this position.Go round and begin again, the position that the photoelectricity sunlight tracking system is adjusted main reflective surface (9) and paid reflective surface (8) automatically keeps sunshine to focus on pot (5) bottom surface all the time.
6. reflective surface support (10) is at 3 and decides face, and three fulcrum arms (12) are scalable, even if lowered in field environment, reflective surface support (10) also can support reflective surface and pan reposefully.Reflective surface support (10) and pot frame (7) etc. can be put into special-purpose support case, are easy to carry.
7. there is stay-warm case (6) pot frame (7) top and connects the dish (14) that overflows, and stay-warm case (6) can make this kitchen range use in windy low-temperature environment, can prevent that pot (5) interior heat scatters and disappears in a large number; Connect the dish (14) that overflows and to prevent that pot interior overflow from polluting reflective surface (9) and causing the reflective surface reflecting effect poor, increases its service life.
8. pot frame (7) is four power bar structures, can make pot (5) baseplane remain level.
