Description

The invention relates to the construction of thermoses for household, and more particularly to large-sized thermoses containing two to three pots.

An object of the invention is to provide a thermos in which there are constructive conditions for pre-boiling food on a stove. E,) of this, it is necessary that the decrease in the temperature of food installed in a thermos does not exceed 3-4 ° С by the end of the first hour, which is unattainable in known large-size thermoses.

This goal is achieved in that the thermos is equipped with a thermal shutter located in the narthex between the housing and the lid. The thermal shutter consists of a horizontal gutter of a closed shape and a ridge interacting with it, and g (the forehead is filled with elastic material (for example, porous rubber, foam rubber, water).

When the thermos is closed with a lid, the thin ridge is immersed in the elastic filling of the gutter, which completely prevents hot air from escaping from the inner chamber, which is the main type of heat loss of known large-sized thermoses.

The gutter may be located in the upper part of the housing or in the lower part of the lid, wherein the comb is respectively attached to the lid or housing. Both of these options are completely equivalent, since the purpose of the invention, the structural elements of the thermal shutter and their interaction are retained.

In order to speed up the process of adding food, it is useful to preheat the inner thermos chamber. This is accomplished by installing additional hot water tanks. For example, if the owner intends to cook dinner in the morning, then at night she puts thermo

sa kettle with boiling water. By morning, the walls of the inner chamber and the heat insulation adjacent to them will be warmed up. Also, in the morning, you can drink enough hot tea without heating.

In FIG. 1 shows a general view of a thermos, including a housing 1 and a cover 2, as well as a vertical section of a thermos: 1 — a visible shell of a thermos (steel sheet, plastic, plywood); 3 - qi thermal insulation (polystyrene foam, foam rubber, straw cutting); 12 - inner chamber (white food tin, heat-resistant plastic); 4 - thermal shutter, including a horizontally located groove 14 (Fig. 11), a ridge 16 interacting with the groove, and elastic filling 15 of the volume of the groove (porous rubber, foam rubber, water). In the inner chamber 12 there are two pots with cooked food.

Figures 2-7, 9, 10 and 12 show variants of additionally shaped additional / containers with hot water (5, 7, 8, 9, 10, 11, 17),.

The body of the thermos can be square or round in plan. The inner chamber has a plan in the form of a square, rectangle or oval, along the long axis of which are placed the handles of pots.

The technical and economic effect is as follows:

0

2-3 times reduction in gas (or other coolant) consumption:

save energy, because pre-cooked food is not stored in the refrigerator, but in a thermos;

save the host labor costs for cooking (0.5 hours instead of the usual 2-3 hours);

there is no need to heat food, since it is stored in a thermos sufficiently hot for 10-12 hours, while vitamins are preserved.

FORMULA AND SECTION

Claims (2)

1. A thermos containing a double-walled body, between which a thermally insulating material is placed, a heat-insulated cover, characterized in that it is provided with a shutter, which is a ridge and a gutter located along the perimeter of the mating surfaces of the body and the cover, and interacting with each other; having a closed circuit, while the cavity of the trough is filled with material that impedes the release of thermal energy into the environment. 2. The thermos according to claim 1, with the exception that it is provided with containers filled with hot water for installing them. in the body cavity. figure 1 A - A fЈ / g.2  5 1837836 AT f && 7 p & Ј, ff Bb 10 rig. at g pЈSc.
