Description

Waterproof flame-stabilizing furnace end

Technical Field

The utility model relates to a combustor especially is relevant with waterproof steady flame furnace end.

Background

With the healthy development of the kitchen electricity industry in China, the requirements of users on household cookers are not limited to the rigid requirements of cooking, and the requirements on appearance, stability, usability and the like are gradually improved. In order to pursue high energy efficiency, most furnace ends increase the fire hole angle with the horizontal direction at present, but cause the condition from the flame easily, and the effective waterproof function of fire hole is difficult to accomplish to cook in-process to most of furnace ends in the market simultaneously, and the user is in the use, and the fire hole is very easily blockked up after the pot overflow, causes hidden danger such as the furnace end can not normally work and the gas burning is insufficient. This project furnace end increases the waterproof groove design in through the fire lid, has solved furnace end use in-process fire hole jam problem, shifts up the design through steady flame hole simultaneously and makes the fire lid have more stable steady flame function, promotes the furnace end comprehensive properties greatly.

Disclosure of Invention

The utility model aims at providing a waterproof flame stabilization furnace end that rational in infrastructure, prevent that the furnace end fire hole from blockking up, flame stabilization function are strong, the furnace end comprehensive properties is high.

To achieve the above object, the present invention is achieved by the following technical solutions. Waterproof steady flame furnace end, under the fire lid seat, on the fire lid seat, big fire lid and little fire lid, the fire lid seat is located the furnace end lower part down, locates on the fire lid seat under the fire lid seat on, big fire lid locates outer lane on the fire lid seat, and little fire lid locates fire lid seat upper center, is equipped with the big fire hole along the circumference distribution in big fire lid outer lane, and big fire hole outer opening is equipped with big fire U-shaped waterproof slot, is equipped with the big fire steady flame fire hole along the circumference distribution above big fire hole, is equipped with big fire steady flame groove in big fire steady flame fire hole outer lane.

The waterproof flame stabilizing furnace end is characterized in that small fire holes distributed along the circumference are formed in the outer ring of the small fire cover, small fire U-shaped waterproof grooves are formed in the outer openings of the small fire holes, small flame stabilizing holes distributed along the circumference are formed in the upper portion of the small fire holes, and small fire stabilizing grooves are formed in the outer ring of the small flame stabilizing holes.

The waterproof flame stabilizing furnace end is characterized in that the fire cover seat of the furnace end is connected with the fire cover seat through a screw in a matched mode, an air inlet is formed in an inner cavity formed between the lower portion of the fire cover seat and the upper portion of the fire cover seat, and the outer side of the air inlet is in reverse large chamfer arrangement.

The included angle A between the reverse large chamfer angle, namely the reverse chamfer angle line, and the horizontal plane of the waterproof flame-stabilizing furnace end is 90-175 degrees.

The utility model discloses owing to adopted above-mentioned technical solution, therefore following beneficial effect has. The first is that the utility model innovatively designs the flame stabilizing fire holes with the big and small fire holes to move upwards and hide, because the angle of the big and small main fire holes is continuously increased to improve the thermal efficiency, the flame stabilizing fire holes which are originally arranged at the lower parts of the fire holes can not effectively stabilize the flame, after the flame stabilizing fire holes are moved upwards, the flame combustion has good stability, the flame is not easy to be released, and the combustion thermal efficiency is improved; (II) be the utility model discloses the innovation has designed down-pressure formula steady flame groove, steady flame hole if not through down-pressure formula steady flame groove then flame still easily from the flame, the design in down-pressure formula steady flame groove makes from steady flame hole spun gas have a suppression of downward direction and join simultaneously with big fire and reach the effect of a steady flame. Thirdly, the utility model innovatively designs the U-shaped water-proof groove with the big and small fire holes, and because of the common conventional fire holes, water or soup can flow into the fire holes when a user uses the water-proof groove, and after the U-shaped water-proof groove is designed, water drops or soup can flow down from the outside of the U shape and can not flow into the fire holes, thereby achieving the effect of preventing blockage; (IV) the utility model discloses the innovation has designed the reverse big chamfer design of air inlet under the fire lid seat, makes the secondary air get into big fire inner circle more easily, makes the burning more abundant to the increasing of heat efficiency.
