Abstract

The utility model relates to a high-efficiency and energy-saving fuel gas stove. Because the existing stove has too much space in the hearth, the furnace wall has no heat insulation layer, and the flue is directly opened on the furnace wall and is close to the burner, the overall thermal efficiency of the stove is low and the consumption is low. The fuel is large, and the utility model is provided with a thermal insulation layer in the hearth of the stove body, and a refractory layer connecting a control ring, a buffer ring, and a furnace body ring on the thermal insulation layer. The distance between the control ring and the bottom of the pot is 2 -4mm, height 20-40mm, control the heat flow around the bottom of the pot, reduce heat consumption, improve thermal efficiency utilization, and move the flue opening to the contact point between the pot and the stove to maximize the use of waste heat, so that the stove can fully Maximize the use of waste heat, improve the efficiency of waste heat utilization, and save fuel and gas.

Description

High-efficiency energy-saving fuel gas stove

Technical field:

The utility model belongs to the technical field of kitchen utensils, in particular to a high-efficiency and energy-saving fuel gas stove.

Background technique:

Because gas and oil stoves are clean, hygienic, fast, and convenient, they are widely used in government agencies, schools, troops, enterprises, institutions, and major hotels. However, due to the large space of the hearth and no heat insulation layer on the furnace wall, and the flue is directly opened on the furnace wall and close to the burner, the overall thermal efficiency of the cooker is low and the fuel consumption is too large. It is not conducive to reducing the cost of use, saving energy and improving the stove is the best way for us to save energy.

Invention content:

The purpose of this utility model is to provide a fuel-saving (gas-saving), high-efficiency and energy-saving fuel gas stove according to the above-mentioned existing defects, which has reasonable design, simple structure, and good fuel-saving and gas-saving effects.

The utility model is achieved in that it comprises a kitchen range body and a hearth therein, and is arranged on the design of a burner and a flue in the hearth. It is characterized in that there is an insulating layer in the furnace, and on the insulating layer is a refractory layer connected by a control ring, a buffer ring, and a bottom ring, and the middle part of the refractory layer and the bottom ring communicates with the burner while the smoke The crossing is moved to the uppermost edge of the contact point between the pot and the stove to maximize the use of waste heat.

The refractory layer control circle described in the utility model is composed of an upper control circle and a lower control circle. The distance between the control circle and the bottom of the pot is 2-4mm, and the height is 20--40mm, so as to control the heat flow around the bottom of the pot and reduce the heat flow. heat loss. The buffer ring is arranged between the upper and lower control rings, and the bottom of the ring is concave, which is used to buffer the heat flow, so that the firepower is uniform and the heating is performed in a circle. The bore bottom ring is located at the lower part of the lower control ring and communicates with the burner to effectively improve combustion efficiency and reduce fuel consumption. The upper part of the upper control ring is a smoke exhaust ring, which is connected with the flue so as to make full use of the heat energy of the smoke from the smoke exhaust ring.

Compared with the prior art, this new type of use has the following advantages and effects: because the heat insulation layer and refractory layer are set in the furnace, the space of the furnace is compressed and moved up, and the distance between the refractory layer control circle and the bottom of the pot is extremely small, which is different from the existing one. Compared with the stove, the space is greatly compressed. The heat generated by the combustion is close to the bottom of the pot, which effectively improves the utilization rate of heat efficiency and avoids unnecessary heat loss. In addition, because the upper and lower control rings, buffer rings and the second combustion chamber are set on the refractory layer, the control The overflow of heat energy is avoided, and at the same time, the incomplete combustion components of the burner can be further fully burned in the second ignition chamber, which effectively improves the combustion efficiency and reduces fuel loss. The edge design of the flue opening can maximize the use of waste heat.
