Abstract

The utility model relates to a cooking stove heated by the solar energy. The cooking stove comprises a plurality of reflectors which reflect and focus the sun light and a stove box positioned on the focusing surface of the sun light. The outer surface of the stove box is coated with a heat absorption layer, and the reflecting surfaces of the reflectors are composed of central circle parts and a series of circular cones or paraboloids. When adjacent reflection mirror faces are folded oppositely, the cones or the paraboloids are in the staggered contact. The whole cooking stove except the stove box can be folded conveniently and compactly.

Description

Portable solar cooking stove

The utility model relates to a kind of kitchen range that utilize solar energy heating.

Under many occasions, as working in the open air or the out on tours exploration, it is difficult obtaining or use common kitchen range (as gas range, electromagnetic stove etc.).In this case, the energy that makes full use of sunshine is best selection, and people thirsted for especially for particularly a kind of compact conformation, solar range easy to carry.

The purpose of this utility model be to provide that a kind of energy is folding, compact conformation and solar range easy to carry.

The purpose of this utility model is achieved in that at least two solar light reflecting mirrors of employing are sunshine reflection and focus on the focusing surface, be provided with a kitchen range case at this focusing surface correspondence position, sunshine is just given the heating of kitchen range case like this, makes the food in the kitchen range case be done ripe.Each solar light reflecting mirror surface is made of a series of circular conical surface parts or parabolic part, and the adjacent mirror face can be folded up face-to-face.All support components adopt collapsible or telescopic structure.For improving solar energy utilization ratio, on the outer surface of kitchen range case, scribble the heat absorption material layer.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.

Fig. 1 is the side view according to the portable type solar energy kitchen range that the utility model proposes.

Fig. 2 is for overlooking the schematic diagram that shows speculum arrangement state along direction shown in the arrow 2 among Fig. 1.

Fig. 3 is the expansion plane of speculum.

Fig. 4 is the folded state diagram of speculum and support component thereof.

Fig. 5 is the schematic diagram of closed state between the reflection speculum.

Portable type solar energy kitchen range 10 provided by the utility model as depicted in figs. 1 and 2, it comprises four speculums 12,14,16 and 18, these speculums are sunshine reflection and focus on the kitchen range case 100 that is placed on the support arm 66.

For making these speculums hinged easily, speculum 12,14,16 and 18 is rectangle, and as shown in Figures 2 and 3, hinge member 22,20 and 24 is hinged together speculum 12,14,16 and 18 successively, and each speculum can be rotated around hinge member.As shown in Figure 2, speculum 12 and 14 and speculum 16 and 18 between angle be (90 °＜＜180 °), speculum 14 and 16 angle are (90 °＜＜180 °).When need were folding, each speculum was pressed direction of arrow rotation among Fig. 2, just obtained the folded state of compactness shown in Figure 4.

Support component makes speculum be supported on the ground at a certain angle, two support components 26 link to each other with 18 with speculum 12 with 36 by pin joint 34 respectively with 28, angle for accommodation reflex mirror and ground, support component 26 and 28 has a Retractive leg respectively, as support component 26 Retractive leg 32 is arranged, it is by 30 lockings of spiral shell select.

By optical principle, the reflecting surface of speculum is the best with the parabolic linear surface, but consider in this device focusing surface be not a point but with the corresponding face of kitchen range case, and the parabolic linear surface takes up space bigger, so mirror surface adopts Fig. 5 and shape shown in Figure 3, at the reflecting surface center of speculum 16 is a circular portion 54, and it is outer to be a series of conical surfaces 58 and 62 etc., and the edge 60 of each conical surface and 64 etc. all is circular.Speculum 18 also has analog structure, and the center is a circular portion 38, and it is outer to be a series of conical surfaces 42,46,50 and 52 etc., and the edge 44 of these conical surfaces and 48 etc. also is circular.But, can fold up face-to-face for making speculum 16 and 18, the central circular part 54 of the central circular part 38 to 16 of speculum 18 is big, the edge of each conical surface that makes speculum 16 and 18 is just in time corresponding to the conical surface central authorities of another speculum, shown in the figure of Fig. 5 middle and lower part, so not only saved the space but also increased stable contact between two speculums.Speculum 12 and 14 has same structure with speculum 18 and 16 respectively.The central circular part of mirror surface can be that the plane also can be paraboloidal core.Above-mentioned each conical surface also can replace with parabolic linear surface or similar curved.The reflecting surface of speculum can be polishing or electroplated metal surface, if with plastic material as basal body of reflector, its reflecting surface should be done calorize and handle.

Kitchen range case 100 is supported by support arm 66, and 66 lower end is positioned at hinge member 20 belows, and its central authorities are supported and traction by supporting leg 70 and link rod 68 respectively, link rod 68 is to bend, as shown in phantom in Figure 1, supporting leg 70 has a Retractive leg 72, and it is by 74 lockings of spiral shell select.Kitchen range case 100 is to be placed in the U-shaped tank tower 76, is even heating, and kitchen range case 100 can rotate by the axle 80 on tank tower.The kitchen range case is made with metal, glass or other heat proof material, and its outer surface scribbles one deck heat absorption material, and as handling the various oxide coatings that obtain with the anode process melanism, purpose is the thermal efficiency that increases the kitchen range case.

Claims (2)

1, a kind of solar range, the speculum and one that comprises at least two reflections and focusing sunlight is positioned at the kitchen range case on the solar light focusing face, it is characterized in that in the described speculum any adjacent two hinged, the reflecting surface of each speculum comprises central circular part and a series of conical surfaces on every side, the edge of these conical surfaces is circular, the diameter of the central circular of two adjacent superimposed speculums part is different, and the difference of these two diameters equals interior external diameter poor of the inner most ring-type conical surface.

2, solar range according to claim 1 is characterized in that the described conical surface can change the parabolic linear surface into.
