The reflector main body 3 includes a plurality of reflectors for reflecting light, and a reflector connecting and fixing member 4 for fixing and supporting the plurality of reflectors in a predetermined form.

First, in the food heater 1 of this invention,
The casing assembly 2 includes an outer casing 5 and an inner casing 6 each made of corrugated cardboard.
and a heat insulating plate 7 inserted between the outer casing 5 and the inner casing 6. The outer casing 5 is assembled by die-cut sheet members 8 made of corrugated cardboard. The outer casing sheet member 8 includes a rectangular bottom wall 9, an outer side wall 11A continuous through valley fold lines 10 forming the four sides of the bottom wall 9, and the outer side wall 1.
It has an inner side wall 11B that is continuous via a valley fold line 12 forming the long side of the outer side wall 1A, and a winding piece 14 that is continuous via a valley fold line 13 that is the short side of the outer side wall 11A. When such a die-cut sheet member 8 is folded along each fold line, an outer casing 5 having a double side wall structure as shown in FIG. 1B is formed. A pull member 15 and a stand member 16 are attached to the outer casing 5. The pull member 15 is
It consists of a band-like member with T-shaped ends 17, and two holes 1 provided in the bottom wall 9 of the outer casing 5.
8, 18, the T-shaped ends 17, 17 are inserted into the middle portion 19 toward the outside of the bottom wall 9.
are being brought out. On the other hand, the stand member 16 is bent in a generally U-shape, and each free end has a pivot shaft 2 facing inwardly from each other.
Opposed side walls 11, 11 of the outer casing 5 are formed of wire members having a diameter of 0,20.

A long and narrow hole 28 is provided along the valley fold line 24 with the valley fold line portion as one side. In the figure, 2
Reference numeral 9 denotes a notch provided at the center of the outer long side of the side wall 25, which forms a gauge point during irradiation with sunlight, which will be described later. The sheet member 22 as shown in FIG. An inner casing 6 as shown is formed. The inner surface of the inner casing 6 is entirely black-treated. The heat retaining plate 7 is composed of a plurality of rectangular panels 30 of a size that can be stored in the casing 5. The heat insulating plate 7 may be configured by alternately stacking panels 30A made of cardboard and panels 30B made of metal foil.

On the other hand, the reflector main body 3 is assembled using cardboard die-cut sheet members 31 as shown in FIG. 3A. The die-cut sheet member 31 is formed by sequentially bending the vertical fold lines 32 in the figure and connecting them via the gluing margins 33 to form four outer side walls 34 having a rectangular cylindrical shape. The inner side wall 37 is continuous through a fold line 35 forming the lower long side and separated from each other by a cut 36, and the outer side wall 34 is continuous via a fold line 38 forming the upper long side. , and a rectangular reflecting plate 40 separated from each other by a notch 39. When the reflective plate 40 is bent and assembled, inner surfaces facing each other are formed as reflective surfaces 40a. The reflective surface 40a may be formed by pasting metal foil or may be coated with a material having metallic luster. In the figure,
41 is formed along each side of the reflective plate,
Each of the holes is a pair of elongated holes, and serves as an insertion hole for a reflecting plate connecting and fixing member, which will be described later. By bending such a sheet member 31 along each folding line and connecting and joining them via the adhesive portions 33, a reflector main body as shown in FIG. 3B is formed. A top surface forming member 42 is attached along the upper edge of the side wall 34 of the assembled reflector main body 3. The top surface forming member 42 is formed of a transparent plastic sheet. The top surface forming member 42 is provided with a line mark 43 and an air vent hole 44 . The line mark 43 is the top surface forming member 42
It is provided at the center of each of the four sides of , and when extended from each other,
They intersect at the center of the top surface forming member 42.

The reflector connecting and fixing member 4 connects the four reflectors 40 of the reflector body 3 to each other, and connects the reflectors 40 to each other at a predetermined angle (facing outward with respect to the vertical line). The angle formed is approximately 45°). The reflecting plate connecting and fixing member 4 is made of a die-cut sheet 45 made of cardboard, and generally has an inverted triangular shape, with each hypotenuse 4
6 and 46 have tabs 47 and 47 that are inserted into elongated holes 41 provided in the reflecting plate 40. The notch 47a of the lug 47 is locked to the lower edge 41a of the elongated hole 41. One surface of the reflecting plate connecting and fixing member 4 is entirely formed by a reflecting surface 45a. In the figure, 48 is a reflection plate fixing reinforcement member,
The vertical part 49 is inserted between the casing assembly 2 and the side wall 34 of the reflector body 3, and the split pin 51 attached to the upper part of the inclined part 50 is made of a bent metal strip member. It is inserted into a small hole 52 provided in the plate 40 and fixed.

A method of using the food heater using solar heat having the above configuration will be explained. First, in the food heater, the reflector connecting fixing member 45 and the reflector fixing reinforcing member 48 are removed, and the reflector 40 is removed.
are stored as a compact unit by folding them overlapping each other to form the top surface of the box. This box-like unit is carried to an appropriate use location, where the reflector 40 is erected and assembled with the reflector connecting and fixing member 45 and the fixing reinforcing member 48. In this state, the casing assembly 2 is pulled out from the bottom side of the reflector body 3, and the casing assembly 2 is further separated into an outer casing and an inner casing. In this state, cooked food stored in a plastic bag, for example, is stored in the inner casing. In this case, the open ends of the plastic bags are passed through the elongated holes 28 provided in the inner casing, and the open ends B and O of the plastic bags V and B are sandwiched between the side wall 25A and the folded piece 27. Insert the inner casing 6 into the outer casing 5. The casing assembly 2 consisting of the outer casing 5 and the inner casing 6 is inserted into the rectangular cylindrical portion of the reflector body 3. This completes the setting of the cooked food. The heater 1 is installed as shown in FIG. 8 with respect to sunlight S and L. At this time, the shadow created by the line mark 43 provided on the top surface forming member due to sunlight is reflected by the mark 29 provided on the inner casing 6.
By aligning the solar rays S and L to the cooked food, it is possible to reliably direct the solar rays S and L toward the cooked food.

As mentioned above, this invention can be said to be economically extremely beneficial as it allows food to be cooked without the need for fuel using an extremely inexpensive device. . In addition, the food heater of this invention has a laminated structure for storing the cooked food, the inner wall surface of the storing portion is completely blackened, and the cooked food inside the casing is placed on the bottom wall. It can be said that this food heater has excellent thermal efficiency and heat retention because it is formed so that it can be held in close contact with the food heater. Furthermore, the solar food heater of this invention usually
It can be stored as a small unit in the folded state, easily carried anywhere, and quickly assembled when in use, making it highly adaptable, especially as a heater for outdoor food preparation. It can be said. moreover,
This food heater that utilizes solar heat is devised by
By adjusting the stand member, the heater device can be set at an appropriate inclination according to the angle of incidence of sunlight, and in this case, the shadow created by the line mark provided on the top surface forming member is reflected by the mark mark provided on the inner casing. By aligning the casing with the casing, sunlight can be easily and reliably irradiated onto the cooked food set inside the inner casing through the reflecting surfaces of the reflecting plate and the connecting and fixing member, which improves handling and operability. It can be said that it is extremely excellent.
