Description

The invention relates to household appliances, in particular to household utensils such as a pot, taganka, cast iron, pot, ladle, frying pan, etc., having, as a rule, a handle or ears for carrying, and also to a heat system, for example, heating devices, for example, water, various products, compositions or materials with an external heater, for example, in the form of a gas burner on a stove in domestic conditions or pilaf in a pan on a fire, etc. As a specific example, we consider the option of accelerated heating of the ladle and pan on a household gas stove, which in essence is suitable for accelerated heating of other objects in size and shape from a different external energy source and in different conditions.

The problem of excessive gas / fuel waste arises due to the fact that the flame tongues of the gas burner (or bonfire) often go beyond the outer surface of the heated container, and therefore, heat / heat is largely simply lost in the ambient air, reducing the heating efficiency and increasing how duration of heating, as well as energy consumption (gas / fuel). Moreover, when the flames do not even reach the outer surface of the heated container, part of the combustion energy is irretrievably lost in the environment, to a greater or lesser extent blowing and cooling the outer surface of the container.

RF patent. A method of manufacturing a pot for cooking hot food (No. 2136202, A47J 33/00, publ. 09/10/1999). The case is made of aluminum folding rectangular shape. There is no accelerated economical heating. SU patent Utensils No. 1567178, A47J 33 - Camping pans without built-in heating devices (traveling pans with one A47J 36/26 burner; other cooking devices heated with gasoline, kerosene, alcohol, etc. F24C burners). The handle of the dishes is made with protection against overheating. A device for heat treatment of food products (patent SU No. 1824181, 06/30/93, bull. N. 24 (71)). The device has a rather complicated design for assembly with tongues and grooves for fixing; energy saving when heating is not provided. Pan - patent No. 2176470 of the Russian Federation, IPC A47J 27/00, publ. 12/10/2001: contains a housing with a flange in the upper part and a cover, characterized in that the flange is a flat horizontal ring with a recess concentrically located in it and made in the last hole. Accelerated heating is not provided. Patent Camp pan - a samovar. RF, No. 141591, IPC: A47J 27/21 contains a housing rigidly connected to a heat-conducting skirt and a smoke pipe, together forming a combustion chamber, inside of which there is a grate-screen. Sufficiently complex design without saving coolant energy. IPC patent A47J 36/36, RU No. 2064285 A method of cooking food in a container with a casing and a device for its implementation provides the supply of hot gas to the bottom of the heated container, shielding the flow of hot gas with its subsequent upward direction between the walls of the container and the walls of the casing, characterized in that the flow of hot gas is pre-twisted. The system is quite bulky and not universal due to the fixed form of the casing. A device for heating water over a gas stove (patent SU 286173) includes a housing connected by a supply pipe through a throttle device with a tee on the pressure line. The design is complex and does not provide significant heat savings for the heater. Patent The device for heating liquid and gas media (RF No. 2231003) contains basically a source of acoustic vibrations, a filter and a closed loop of the circulating mass of the coolant. It is complex and does not minimize energy consumption during heating. Patent A device for heating a liquid (RF No. 2517986) does not solve the problem of maximizing the use of coolant energy and is cumbersome (publ. 06/10/2014). Also known is an electric stove energy-saving, multi-functional, environmentally friendly and safe for humans - RF patent No. 2475679, publ. 02/20/2013, class F24C 7/00 Furnaces or stoves heated by electricity and class F24C 13/00. The system is bulky, expensive and has low heating efficiency. The main element of the stove is an injection gas burner - a device in which air and combustible gas are mixed. Ignition of the mixture occurs at its exit from the burner, consisting of a divider (metal bell), necessary to ensure uniform burning, and a lid covering the divider from above.

The closest in essence to the claimed technical solution is the prototype - Patent MPK A47J 36/36, RU No. 2142099 Device for saving thermal energy during cooking on gas stoves, which contains a heat-insulating tray with a hole for the torch of a gas burner, a cylinder enclosing a container for cooking, and a lid, allowing to limit the space for convection air flows around the tank and heat loss. The design includes a heat-insulating tray with an opening for the torch of the burner, a container for cooking or frying, a guarding cylinder and a lid. A rather complex design, far from universality, only partially saving the energy of the coolant.

The purpose of the proposal is to develop a fairly unified equipment in the form of a heat-resistant outer jacket for household utensils, accelerating the heating of food or the environment (for example, solutions) while saving energy and heat carrier.

Technically, this goal has been achieved due to the design of a heat-resistant fit jacket that covers a heated container with its contents on the outside with a constant gap.

The essence of development is shown in Fig. 1, where indicated

for a): 1 - heater (energy or coolant in the form of gas or other combustible medium / firewood, coal, etc. /) - in this case, it is a gas stove with a burner and supports for dishes heated by the flame of the flame; 2 - capacity (for example, a heated pan); 3 - shirt shaped, outer, heat-resistant with low thermal conductivity; 4 - shaped bent bottom of the shirt (with a conical and vertical part); 5 - handles for carrying shirts, offset in the vertical and horizontal plane with respect to pos. 6; 6 - ears for carrying pans passing through holes / grooves for them made in a shirt 3; 7 - cover (removable, may be absent); 8 - two halves of a shirt 3; 9 - line connector or connection of the two halves of the shirt 3; 10 - a connecting device (for example, in the form of a hook placed on one of the halves 8 of the shirt 3; 11 - a pin fixed on the other half 8 for connection with the hook 10; 12 - heat-resistant stops, located around the circumference (at least three), on the inner surface of the shirt 3; 13 - circular flanging of the upper part of the shirt 3.

Description of the proposed equipment in statics.

Situation a) with heating the pan of a cylindrical shape of a pan (container), which is installed on a lit gas stove burner. Before heating, a shirt 3 must be worn on the pan, the two halves of which are connected by at least one hook lock 10 on the opposite sides of the pan body, using, in addition to the hook, pin 11. At the same time, the fastening points of the handles 5 for carrying the shirt 3 in a vertical plane and horizontally do not coincide with the mounting positions of the ears 6 capacity 2 / pan /. If the pan is high, then the put on shirt may have two locking hooks on each side with a gap between their location of approximately 1/3 of the distance from the total height of the pan to ensure overall rigidity of fixing the connection of the two halves 8 of the shirt 3. The cover 7 - removable can be on heated capacity or absent. So that the worn shirt 3 on the container 2 could not jump down when the ears 6 for carrying the pan are missing, then a circular flanging 13 of the upper part of the heated container is provided, which fixes the position of the container above the heater 1. Heat-resistant limiters 12 located around the circumference (at least three) provide a constant gap between the jacket 3 and the walls of the heated container / pan / 2.

At its core, situation b) for heating the contents of the bucket 2 is similar to the option just described. A removable shirt 3 is worn on a bucket, the carrying handle 6 of which extends into the hole or groove in the shirt 3. The handle 5 for carrying the shirt with respect to the handle of the bucket is offset both vertically and horizontally. Circular flanging 13 insures the shirt 3 from possible falling down on the heater 1. In this embodiment, both halves 8 of the shirt 3 are connected to one another by a loop 10. The second connection of these halves of the shirt from the opposite side of the heated container can be fixed, for example, with a hook as previously described.

Position c) presents examples of some forms of contact between the surfaces of the two halves 8 of the shirt 3 to be connected, which ensure rigid fixation of this equipment.

Situation d) provides for the option of heating the shaped container 2, different from the considered (pan and ladle). It can be a taganka, a cast-iron, a pot or other shaped shaped heated object. In this case, a shirt 3 is also used in the form of a heated object / article. The connector / connection line 9 of the two halves 8 of the shirt 3 can be arranged either horizontally or vertically using, for example, hooks or hooks and loops 10. The lower part of the shirt 3 in all cases has a formally bent lower part (with diverging conical and vertical parts ) In addition, heat-resistant stoppers 12 are rigidly fixed on the inside of the shirt 3 around the circumference or immediately made during manufacture, which provide a constant gap between the jacket and the container and rely on a heated container located inside the jacket, and at the same time prevent the shirt from falling down onto the heater 1.

Description of the principle of operation of the developed equipment in the form of a shaped outer heat-resistant shirt for household utensils, accelerating the heating process while saving energy carrier.

Initially, consider the process of heating the contents in a pan on a gas stove. Put, using the handles 5, on the container / pan 2 a shirt 3, consisting of two halves 8 fastened together, passing the ears of the pan 6 into the holes or grooves of the shirt for carrying it. Secure both put on halves 8 in one piece using the hooks 10 made, located at least one on the opposite sides along the line of connector 9. Fill the container 2, for example with water. Turn on the gas supply and light the heater 1. The flames will to a greater or lesser extent (like heat) not only heat the pan, but also go outside the heated container. An efficient bent form 4 of the lower part of the shirt 3 (with an expanding cone and vertical part) contributes to the efficient capture of the energy lost, in addition, even with the presence of heat-resistant limiters, uniformity and acceleration of the heating of the tank over its entire height from the sides is ensured. The conical part departs from the outer heated surface of the container farther than the cylindrical part of the shirt, capturing a possible wider distribution of energy flows from the heater; while the vertical bottom of the shirt almost completely prevents heat loss during heating. After heating, it is necessary either to turn off the gas, or to transfer it to the side by the ears of the pan, where you can release the fastening of the connected two halves of the shirt by opening the hooks. After that, both halves for the handles 5 to transfer and put or put on a fireproof surface. Note: if the heated container is high, it is advisable to equip it with two pairs of hooks from two opposite sides or two loops and two pairs of hooks from two opposite sides with a vertical distance of approximately 1/3 of the total height of the heated container for greater rigidity of the mounted jacket.

Essentially, the options for heating the contents of the bucket or shaped container are completely similar to the described method. Therefore, one should only pay attention to the following. It is known that pots, ladles, cast-iron and other kitchen utensils are produced by the industry of certain sizes and shapes in bulk quantities. Therefore, for them, the auxiliary equipment presented here should also be produced in bulk in accordance with the applicable standards for cookware. In one embodiment, made by the author using stainless steel shirts as a material, the ladle heating time was reduced by almost 22%, which indicates the possibility of obtaining a large economic effect from reducing energy consumption of energy sources, reducing the heating procedure and reducing the pollution of the kitchen or other space with combustion products, which badly affects, as you know, human health and the environment. In fact, a similar effect will be obtained by heating a container (for example, a bucket or a pot, or a pan) on a fire.
