RU2417729C2 - Sun-ray collector - vacuum flask accumulator - Google Patents

Abstract

FIELD: personal use articles.

SUBSTANCE: sun-ray collector - vacuum flask accumulator relates to devices that apply sun thermal energy to heat water, boil food, bake bread, etc. The sun-ray collector includes a vacuum flask accumulator, which comprises a body with double walls and an internal heat insulation, a cover, a bottom with the possibility of disconnection. The body is made with the possibility to place a boiling reservoir in it, the cover of which is equipped with a gate and a valve. In the upper part of the body there is a power plant, which consists of converging lenses with rims fixed on the screen panel made of a copper sheet, as a result of which the sun-ray energy is converted into high-degree thermal energy. Branches in the form of copper tapes coated with incombustible heat insulation are welded to the copper sheet of the vacuum flask accumulator, as a result of which heat losses of the boiling reservoir during cooking are reduced.

EFFECT: provision of possibility to keep food in hot condition.

Description

The invention relates to devices that use the thermal energy of the sun to heat water, cook food, bake bread, etc. and maintain food in a hot state, and can be used in catering, in the private sector, in the field at the dachas.

A known solar collector used on satellites, which converts the sun's rays into electric current. Of course, electric current can also be converted into thermal energy, but it is still very expensive.

There are developments and the direct conversion of sunlight into thermal energy (see the Readers Digest, illustrated Atlas of the World 2002 London - New York - Montreal - Moscow, p. 51). The Solar Bakery is a wide plate of polished metal sheets that focuses the sun's rays onto the oven. On a clear day, this energy is enough to maintain the necessary temperature for baking bread. Judging by the photographs in the book, the diameter of such a plate is at least four to five meters. Hence the conclusion that this principle of using sunlight is ineffective, since it is not able to increase the temperature of the beam by several tens of times, while reducing the dimensions of the device, it simply collects and concentrates the rays (analog).

There is a patent for an invention called "Universal thermos-accumulator, RU 2329755 C2", where food is prepared using various external warm energy. This device is taken as a prototype.

The technical result is the conversion of the solar radiation energy of the sun into high-degree thermal energy, while reducing the heat loss of the cooking capacity when cooking food, increasing the efficiency.

The specified technical result is achieved by the implementation of the solar beam collector.

Figure 2 shows the solar beam collector, including a thermos battery in cross section without a thermos cover and a pallet in working condition.

Figure 3 shows the heat conductor emitter in the form of a pallet.

Figure 4 shows the cover of a thermos.

The solar radiation collector, including a thermos battery, contains a housing with double walls 1 and 2 (Fig. 1, 2) with thermal insulation. Outside in the upper and lower parts of the body fasteners 4 are attached for fastening the cover 10 and the bottom 9 (figure 2). 5 radial protrusions are stamped inside the casing, which serve to arrange pans, gratings on them.

In the lower part of the thermos to transfer heat from an external source of thermal energy to the cooking vessel 15 (Fig. 1, 2) there is a copper sheet heat transfer unit, which is a tray 7 (Fig. 3) with layers in the form of tapes 6, which serve for additional thermal contacts a heat source with a tank, for better contact, they are spring-loaded with a spring 8 (Figs. 1, 2, 3). The removable bottom 9 (figure 2) is double with thermal insulation and three hooks 11, fastened with fasteners on the sides 4. The cover 10 (figure 4) is double with intermediate thermal insulation, has three hooks 11 on top for fastening with fasteners 4. For adjustment temperature and steam release during cooking there is an insulated flap 13 (figure 4) with a safety valve 14. Inside the thermos there is a container 15 (figure 1, 2). To the thermos can be given a device in the form of a tagan.

A sun-beam collector, consisting of a battery 33 (FIGS. 1, 2) of collective lenses 16 with their frames 17 mounted on the grating panel 18 with holes slightly smaller than the diameter of the lenses, a screen 19 made of a copper sheet blackened on top is located parallel to the lens panel below non-combustible substance.

A non-combustible thermal insulation with holes against the lenses is applied on top of the sheet. Bottom of the sheet are welded branches in the form of copper strips 20 (figure 1, 2) and wrapped in non-combustible thermal insulation. Between the panel with lenses and the screen, a copper sheet, in the middle at the base of the screen, a screw 21 with a nut 22, which serves to adjust the lenses relative to the screen, and four guide racks 23 with springs 24, located at the edges of the screen, and panels serving for uniform parallel the position of the panel relative to the screen is a copper sheet. On top of the copper sheet is a heater 25 made of non-combustible material with corresponding holes against the lenses for the rays to pass to the screen - a copper sheet. To mount the power installation on a thermos there are two mounting posts 26 included in the bracket of the thermos 27, and a sliding strut 28 with a stop 29, which serves to adjust when aiming the power plant in the sun. On the sides of the solar beam collector there is an insulated canopy 31 with a transparent apron 32. A tube 34 is drawn from the container lid.

The solar radiation collector, including a thermos battery, is used as follows: when using a thermos during cooking, for example, when using a source of energy from the sun, the lid of the thermos 10 (figure 4) is removed, the required capacity 15 is put into the thermos (figure 2 ) with the corresponding product, a solitice-collector is placed above the thermos, while the fastening posts 26 and the spacer stop 30 are inserted into the corresponding brackets 27 and 28, and the copper strips 20 are attached to the container 15 and encircled by a spring 8, direct the collector to the sun, installing while I am panel 33 perpendicular to the sun. Then adjust the lens panel with a nut 22, choosing the appropriate distance between the lens panel and the screen 19, achieving the corresponding luminous points on the screen. Moreover, the smaller the luminous print on the screen, the higher its temperature, and vice versa. With a combination of hot spots, the sheet heats up and heat is transmitted through copper strips to the container.

When cooking the product, periodically folding the apron of the canopy 32, you can stir the contents of the pan. After cooking, removing the collector, you can close the thermos with a thermos lid so that the food is hot for a while.

In order for all the luminous points on the screen to be of the same diameter, and hence temperature, the lenses on the panel must be selected with the same diameter d, for example d = 80 mm, and with the same magnifying force, for example 10 diopters (diopter). The optical power of a system of several closely assembled collective lenses is equal to the algebraic sum of the optical powers of each of the lenses individually

D = D ₁ + D ₂ + ...
