Description

 The device relates to the field of energy-saving technologies.

 Widely known methods of heat conservation during heat supply by wrapping network pipes with glass and mineral wool having thermal conductivity are several orders of magnitude less than metal and hot water flowing through the pipes.

 Thermos devices are widely known, which delay the loss of thermal energy after cooking.

 A device for saving thermal energy during cooking on gas stoves according to the patent of the Russian Federation 2064285, cl. A 47 J 36/36, 07.27.96.

 The device includes a cylindrical screen with vertical walls located at some distance around the heated vessel, the lower edge of which is located below the bottom of the heated vessel, inside the cylindrical screen, below the bottom of the heated vessel there is a twisting element, which is a system of curved guide vanes connected in the center.

 The objective of the invention is the creation of a device that allows to reduce convective heat loss, and, accordingly, the gas flow rate during cooking.

 The formulated problem is solved due to the fact that the device for saving thermal energy during cooking on gas stoves, including a cylinder enclosing a container for cooking or frying, contains a heat-insulating tray installed on the gas burner with an opening for the torch of the burner on which the container is installed, and a lid covering the cylinder from above so that the space around the container is limited by a heat-insulating tray, cylinder and lid.

 The drawing shows a device for saving thermal energy during cooking on gas stoves. Positions indicate the following: 1 - heat-insulating pan with a hole for the torch torch 2, 3 - container for cooking or frying, 4 - enclosing cylinder, 5 - cover.

 The device operates as follows.

 A heat-insulating tray 1 with a hole for the torch 2 is installed on the gas burner, onto which a container (pot or frying pan) 3 loaded for cooking or frying is installed, and from the side this container is enclosed by a cylinder 4, which is covered with a lid on top.

 In this case, the heat transfer from the tank 3 to the surrounding space is significantly reduced due to the fact that the thermal conductivity of the air enclosed between the tank 3 and the device consisting of elements 1, 4, 5 is less than the metal of the tank 3 and the liquid contained in it. Energy efficiency during cooking increases.

 The device can be widely used in kitchens for cooking, it will help reduce gas consumption and, accordingly, pay for it in the presence of gas meters.
